one,Electric car canopy product materials

1. Use high -tech composite materials (FRP) to production and production.

2. Use imported stainless steel pipes to production.

3. Use PC endurance board to produce panels and side panels.

4. Use a special electric wiper to automatically scrape the rain.

2. Introduction to electric cars rain canopy materials

1. The characteristics of FRP: light quality, high strength, anti -corrosion, insulation.Its intensity is several times that of ordinary plastic boards,The intensity is greater than steel and aluminum.FRP board has the characteristics of high temperature resistance, aging resistance, friction resistance.

2. Features of stainless steel: good ductility, corrosion resistance, good thermal resistance, high clean and smoothness.Because it is not necessarySurface treatment, so it is simple and simple, and the welding performance is good.

3. Features of PC endurance board: good light transmission, difficulty, weather resistance, temperature resistance, good processing, light weight.

Third, the electric car raindrops are good or the raincoat is good

1. Convenience

First of all, in terms of convenience, the convenience of the puff may be higher. After all, it is sufficient to install it directly. You dont need to wear it frequently like a raincoat.There is no problem of folding and cleaning after arriving at home. Although because of the larger rhizon, it will affect the convenience of some electric vehicles on parking, but it is relatively high.Come to block the sun.

2. Show rain

From the perspective of rain -covering, the two should be similar. Although the area of the rain shed looks large, the actual rain covering effect is not so ideal. When the car is stopped, the car will still be wet by the rain and not wet.There is less, and it is easy to let rainfish in during the driving process, especially under the influence of some winds in winter, the angle of rainwater falling will not be straight up and down.It will also appear on the raincoat. Basically, the rain that can be covered by the canopy can be covered. Rainwear is generally no problem, and the rainfall of the raincoat is not too good!

3. security

As for safety, it is definitely a lot better. At present, many cities are already forced to remove the rails, because the safety of the canopy is not enough.After installing the rain shed, the resistance of the electric vehicle is obviously much larger than the non -installed. This will not only cause a greater burden on the battery of the electric vehicle, but also affect its flexibility in the operation and other operations. In addition,, in addition,, in addition,The canopy also significantly increases the height and width of the electric vehicle, which will affect the pedestrian on the roadside to a certain extent, and increase the chance of the pedestrian of electric vehicles.If you stop on the side of the road, it is easy to be blown down by the wind. If the pedestrian does not pay attention, it will be easily crushed by the car, and the raincoat will not have these concerns at all.

Overall, although the rhizon is more convenient than a raincoat, considering it from safety, Xiaobian suggested that everyone is better to choose Raincoats when choosing electric vehicles.Wear some, and you ca nt put the rain directly in the car, but it is really much better in safety. It is obviously not worth it!

[Dome Tent] The roof Tent is practical? The roof Tent gives you a home on the roof

The roof Tent is still a fresh thing for many friends. Some people have heard of it but have never seen it. Some people may have never heard of it. What is the roof Tent?Xiaobian will explain to you the top Tent.

As the name suggests, the roof Tent is a Tent installed on the roof, what?Can I still have a Tent on the roof?Yes, you did not hear it wrong.

Can the roof to bear such a weight?Will it be crushed?

In principle, the roof is 4-5 times that of the car itself, which is the tonnage level. Generally, the roof Tent is about 50kg. In addition, the weight of a family of three is calculated according to 250 kg.In the case, the roof bearing is about 300 kilograms, and everyone does not need to worry about sleeping on the roof at all.

Will you fall when you sleep at night?

Generally, there are railings on both sides of the roof Tent. People who sleep too honestly will not happen from the roof. Of course, the sleepwalking is not counted!

Can only off -road vehicles be installed?Can other cars be installed?

Generally, as long as the area of the roof is larger than the area of the Tent base, it can be installed, such as off -road vehicles, SUVs, sedan cars, etc. The vehicles that cannot be installed are: small vehicles, soft roofs and unfoot vehicles.

Can I drive on a high road?

Here I want to remind everyone: Can't build it on the road, obviously super high, and will be stopped by the police uncle.When driving on the road, you can put away the Tent. Generally, the Tent that is put away will not be super high. If you can't put it directly, you need to remove it.

Regarding the performance of different tents and structures, the performance of the wind and rain, rain, and insulation is different.In addition, different roof tents have different installation methods, which need to be installed according to different products installation methods.

As self -driving tour continues to heat up, the roof Tent has become one of the optional equipment for tourists, and is gradually favored by people. So what are the specific advantages of the roof Tent?

1. The roof Tent replaces the expensive RV and avoids the troubles of not being able to order in the hotel.

2. Compared with the ground Tent, the roof Tent is placed on the roof. As long as the vehicle can reach, the Outdoor Tent can be camped, which is convenient and fast.

3. Compared with the humid environment of the ground Tent, place Outdoor tents on the roof, and with a soft sleeping pad, the comfort is better.

4. Avoid the snake bite that the ground Tent will encounter in the wild, the danger of beast attack.

5. The field of view on the roof is more open, watch the scenery, and take pictures, which is more comfortable.

[navigation System] What are the working principles of the GBS navigation system?

Common GPS navigation systems are generally divided into five forms: mobile phone, PDA, multimedia, vehicle -mounted, notebook types.With the popularity of smartphones and mobile phones of PDA functions, the first three forms have begun to cross.In addition to the products that are integrated with the CD machine mentioned earlier, the GPS that comes with the original car of many models also belongs to this type.The convenience of notebook products has been limited in terms of use. In addition to some enthusiasts, few people use it for car navigation.

Types of GPS navigation System

1. mobile phone GPS

The Nokia series mobile phone using the S60 intelligent system is a typical representative of the mobile phone GPS navigation system.A GPS signal receiving module LD-3W is connected through the Bluetooth system (other models include LD-1W, LD-4W), and navigation operations can be performed through the navigation software in the mobile phone.

In general, the mobile navigation system is easy to carry. A small module will not become a burden at all. The price is relatively low in price than many GPS products, especially when you have a S60 phone, you only need to pay more 700 yuan more.You can get detailed navigation functions on the left and right.Of course, you can also buy a 1,500 yuan S60 mobile phone after getting a module.

2. PDA -type GPS

There are many PDA mobile phones in the market now. Dopod is a major brand. It has the functions of mobile phones and the practicality of PDA, which makes many business people feel a lot of affection for such products.After all, compared with the S60 system, whether it is the PALM system and the WindowsMobile system, the various types of software supporting are richer and the product is more functional.Of course, the navigation function of such products sometimes requires the Bluetooth GPS receiving module.

Because the PDA -type GPS is placed in the fuselage in the end of the navigation system, it is best to pay attention to the position of the body at all times. It is best to always place it under the front windshield.

3. Multimedia GPS

There are also some people who call this type of product as a car GPS. It can be understood so that they have almost no other functions except for use in the car.It is also because of the single nature of this function that can make them easier and practical.

This type of GPS also has a variety of prices according to different functions. In addition to individual low-priced or high-priced models, the main product price is concentrated in the range of 3,000-5000 yuan. The GPS navigation system in this range is also the most in the market at present the market.Mainstream.

Most car owners prefer the main reason for multimedia GPSs to be simple and easy to use.

4. Vehicle GPS, Notebook GPS

There is nothing to talk about these two products. The price of GPS integrating with the head of the machine has always been high. If it is not for higher requirements for the audio and video entertainment system itself, then choosing this system is entirely chargingBig.In addition to paying a higher price when buying a car when buying a car, the later map upgrade is also very high. Generally, a DVD map disc is nearly 1,000 yuan.

And the notebook GPS is more in a state of fever and play. Although the notebook is already small, it still cannot be fixed by a suction cup just as other products. Holding a 10 -inch guy on the car for navigation as a navigation on the car for navigation.It is not easy. It is more suitable for GPS enthusiasts to test, modify or software trials of homemade maps.

navigation system work principle

1. Orientation correction

1. Positioning

Find the location and rely on the synthetic positioning method.The method is to turn the route unit continuously with the quantity and angle.This process includes the accumulation of errors, but these errors are constantly compensated with the position of the digital map (map matching).Due to the GPS satellite positioning system, the vehicle is beyond the short -distance travel of the digital road network or after the shipping or railway transportation, the navigation system can still navigate navigable navigation without any problems.

2. Sensor

In order to find positions, two wheel sensors are often used to determine the changes in the journey and direction, and the absolute direction of traveling travel is determined by the ground magnetic sensor.

In essence, when traveling outside the range of digital maps, the GPS positioning system correction large sensor interference, or determines the revision point of the storage road network.A more modern system requires only a simple travel signal. For example, it often uses speed to determine the volume control of automobile radio.The changes in the direction are determined by a partiality sensor (gyroscope).The geomagnetic sensor is superfluous, and now it can determine the absolute direction of travel through the Doppler effect from the CP signal.

2. Receive destination

1. Name address record

Digital CD map contains name address records.Therefore, the destination can be logged in as an address. All regional catalogs (towns, villages) of all CDs can be used to find the required targets, and list the names of the storage road/street in turn.In order to further find out the destination, it is possible to find the road/street crossroads or street numbers.However, the displayed house number is still very limited, because it is necessary to clarify that the data costs too much.Some drivers rarely know the address of the destination, such as airports, railway stations, service platforms, car parking lots and more places.For this reason, the classification address records the address (POIS) that these people often care about.Use these addresses to log in or even find gas stations near the vehicle.The place where the destination is marked or calls the previously stored address on the map display is further choice.

2. Travel guide

As a reasonable development of POIS, CDS is now available as a travel guide. It is the result of joint cooperation between publishing companies and digital map manufacturers.For example: These CDSs can be used to find hotels near destinations.CDS information also includes the size, price and facilities of POIS.

Third, path calculation

1. Destination selection

It must be able to adapt to the path of the driver's hope.In many systems, optimize configuration with driving time or mileage.Path computing should be noticed at certain homework, such as avoiding highways/car highways, ferry connections and toll sections.Once the destination is determined, the initial calculation of the destination must be completed in half a minute.If the driver breaks away from the recommended path, this requires the system to re -calculate the path, and it is still fast.To select the alternative path, the driver presses the button to bypass the congestion section forward.

2. Dynamic path selection

Driving automatically through the traffic blocking area automatically, you can use RDS-TMC to encode the estimation of traffic information to achieve.This information can be received by RDS or GSM.

Fourth, path guidance

1. Decision of the path

Path guidance is achieved by comparing the current position of the vehicle to the path calculated by the computer.After a comprehensive analysis of the existing sections and the path that will continue to drive, the system can determine whether the driver must change the direction, or continue to follow the current road.

2. Recommend path and direction

Proposal and guidance in paths and directions are the first and first prompts.This allows the driver to run according to the prompt without affecting its operation.If it is possible in the scope (instrument panel) of the Lord, a simple graphic display is installed, and the driver can better grasp the direction.The conciseness of the sound and graphical indicator direction is the decisive factor of the quality of the path guidance.It is not the first choice to determine the driving direction from the display map, because it will disperse the driver's attention.

3. Dynamic path

Transportation blocking is automatically detoured by the traffic information code.This information code is silent in the traffic information channel (RDS-TMC) of the radio data system and is published parallel to the radio program.They have been included in the GSM service.

Five, map display

According to the design of the system, the map can be displayed with color monitors, and the map ratio is between 1: 8000 and 1: 16X10.Observe adjacent or farther routes according to the graphic ratio.The driver's orientation is based on the support of the background information of topography. They show that such as lakes, rivers, ditches, high -rise areas, railways and forests.

Six, road map storage

CD-ROM has become the main media of the storage road map.The storage structure of the data is the proprietary technology (confidential) of the manufacturer and significantly affect the performance of the system.For this reason, the current CDS on the market is a system of different manufacturers and is not compatible with each other.We are trying to standardize navigation CDS.

Due to the development of the digital region, the integrity of the road network and the increasing increase of additional information resources, the capacity of the CD-ROM (seemingly so huge) in the foreseeable future will be consumed.Digital universal CD (DVD), its capacity is much more than CD-ROM, and will definitely become its successor.& gt; & gt; GPS navigator ten brands

1. Is it useful for the windshield of the car?

Vehicle windshield Shading cloth is commonly known as car shade gear. It can reduce the temperature in the car to a certain extent and protect the instrumental seat equipment in the car, which has a certain effect.The material of the Shading is basically made of aluminum foil and multi -layer air bubble film. The bubble film has good strength, toughness, and anti -impact performance.Aluminum foil has reflected light, which reduces heat radiation and has low thermal radiation conduction capabilities.The sun is shot on the obstruction, and some of the heat will be blocked, and the ultraviolet rays will be reflected by aluminum foil.

The car shade gear can avoid the damage of the leather seats and the instrument board. The direct sun exposure of the sun will make the temperature in the car up to 70 degrees. Not only is the center console shell easily deform, but the instrument and other equipment on the dashboard are also due to the reason.High temperature damage, such as aging components, pins, welding, etc., can effectively avoid direct sunlight.

Second, what are the types of car Shading?

1. Follow -ups

There are not many varieties of the front oblong. There are generally two types of aluminum foil and non -woven fabrics.The general "light board" type and pattern type of aluminum foil are generally 60*130cm in size, suitable for most small cars.The aluminum foil and thermal insulation with suction cups are easy to use. After expanding, use a suction cup to suck it in the front windshield or in the rear window glass.

2. Rear Shading

The rear sunrise is generally prepared for the guests. Some high -end vehicles are the original configuration.The rear Shading gear.

3. Side Shading

When driving in summer, the sunlight from the side window is still very powerful.The effective film effect is not very ideal. It will still be hot and hot, and the sideways have a good effect.The side Shading gear is divided into two types: ordinary gauze net and electrostatic stickers. The ordinary gauze -net sideways generally have two suction cups. The advantage is that it is more convenient to remove it. The disadvantage is that it is easy to fall.The static sticker side shade gear has a good effect, which can be pasted directly on the glass and can be reused.

Third, which car shade gear is better

1. The choice of car Shading board material

At present, the most on the market is the material of the aluminum film PVC. The effective reflection light of the aluminum film and the internal PVC bubbles effectively isolate the heat of thermal energy can the heat insulation and cooling effect.Therefore, the size of the aluminum film and the thickness of the PVC material determine the effect of use.When buying this kind of Shading, it is best to choose a model with suction cups. Although it will work more when it is placed, it is easier to fall from the inside of the glass.EssenceIt is recommended that you choose as much as possible when buying as much as possible. The effect is definitely better than ordinary ones.

2. Selection of the color of the car shadeboard

Different colors have different reflections and reflections on light, whether it is front or side gear.Black, red, and some warm colors are not recommended. Black is the most hot.The coolness of warm colors in visual and sensory is also greatly reduced.It is recommended to use the color of blue, green and white.Different Shading effects of car sunboard are also different.

3. Use the car shade board before and after

Many times the riders will cover the side when they look at the sun, so the effect of Shading is also reduced by 40%.It is not just the side of light to increase the temperature. The reflection of light is everywhere. If it is used with a side gear, the effect will be better.The choice of car aphrodisiac material has the most direct relationship with the sunshade effect.
