What is the design principle of car surrounding, car body surrounding?

In fact, it is the external spoiler of the body, and the car surround is a popular name.

The main function is to reduce the reverse airflow generated when the car is driving, and at the same time increase the downforce of the car. To make the car run more smoothly, so as to reduce fuel consumption, this is the category of aerodynamics, we consumers or ordinary students do not go to the depth, do not understand...

If you buy a big surrounding**, you can have it, and you can also have 4S stores.

Here's what I searched from the internet:

1.The large envelope is basically divided into two categories: pump handle and lip style, of which the encirclement of the pump handle is to remove the original front and rear bars as a whole, and then install another pump handle. The lip type is surrounded by a half-cut lower lip on the original bumper, and the quality and installation technology of this type of bracket are extremely high.

2. How to choose the right large surround for your car: (1) Engine cover: light weight, good strength, and can withstand high temperatures.

It's best to take the heat away from the engine. (2) Lip: The lip is the most prominent AERO PARTS with personality, and the owner of the installation is also the most!

3) Front Pump Spoiler: The popular Canard is arguably the most effective aero parts for a little more down force at the front of the car, and the number of installers is growing day by day. (4) GT-WING, the gap between the main wing and the body is less than 2cm, if it exceeds this number, the length of the two ends of the main wing and the door sand plate should be reserved on each side).

5) Skirt: The distance between the height of the car and the ground after the envelope is installed shall not be less than 9cm (about the height of a pack of cigarettes). The distance between the catalytic shield and the ground should not be less than 5cm.

So you should pay attention!

In China, the main materials of the large encirclement kit are: (1) (ABS plastic) This kind of product is formed by vacuum blister, so the thickness is thin and the toughness is average. (2) (PU plastic) Because this type of product is injection molded at low temperature, it has extremely high flexibility and strength, and at the same time, the fit with the body is also the best, and the command period is also long.

It is the best of the three materials. (3) (resin fiber material), such products are cheaper and have more styles, so they have become the first choice of many car owners. If you want to buy this product, you should pay attention to the following points:

Good toughness and torsional resistance; Heat-resistant and non-deforming; The surface should be smooth and lightweight; The degree of tightness with the body should be high; This way you'll be able to choose the one you want!

The car surround is composed of the front surround, the rear pure envelope and the side surround. There are two forms of front and rear surrounding: fully enclosed and semi-encircled. The full envelope type is to remove the original bumper, and then install a large surrounding, or partially add decorative parts, which is not possible.

Design and production of car enclosures.

Design principles (1) the principle of integrity to the car front, rear, left and right envelopes as a whole to imitate the design of this line. (2) The principle of coordination: the shape and color of each envelope.

There are two main materials for making large surrounding: plastic and fiberglass. (1) Plastic: This material has good forming properties and makes a big finger.

3. The design principles of the large surrounding: (1) Integral (front, rear, left, right) (2) Coordination (coordination of shape and color and body) (3) Safety (can not affect the performance of the vehicle and driving safety) (4) Standardization (in line with the national regulations on disturbance and shouting) (5) Ornamental (beautiful and generous, in line with the aesthetic needs of consumers) Fourth, the installation steps of the large surround (1) the selection of large surround decoration parts 1, the model selection of the current decorative parts manufacturers produce large envelope assembly, Basically, they are designed and made based on the models of Teqinedin.

Security principles. After the car is installed in a large surrounding, it must not disturb the vertical pants to affect the performance of the whole fiber key car and driving safety, and the road surface should be considered in the design, and all trims should be kept at a certain distance (at least 20cm) from the ground and the simple surface

Design principles (1) The principle of integrity should be designed as a whole for the front, rear, left and right envelopes of the car.

Beautiful and generous, in line with the needs of consumers to respect the United States) Fourth, the installation steps of the large surround (1) the selection of large envelope decoration parts 1, the model selection macro draft is selected At present, the large envelope assembly produced by the decoration manufacturers is basically designed and made based on the specific model.

Side brackets are also known as side bumper surrounds or side bumper skirts. Second, the design and production of the car envelope 1Design Principles (1) The principle of integrity should be designed as a whole for the front, rear and left and right envelopes of the car.

2) The principle of coordination The shape and color of each envelope should be coordinated with the body. (3) The principle of safety section cracking After the car is installed, the whole vehicle must not be affected.

I'm sorry, we can't do this question, you can ask the people around you or go to the relevant unit, I wish you a happy life.

Design and production of car enclosures. 1.Design principles.

1) The principle of wholeness. It is necessary to design the front, rear, left and right envelopes of the car as a whole2) The principle of coordination.

The type and color of each envelope should be coordinated with the body.

For example, it is installed on the bumper, similar to a duck lip, or made in the style of a wind shovel, because the past surround is attached to the original bumper foundation, which plays a role in aesthetics, increases downforce and reduces the drag coefficient.

For example, side skirts mounted on the side of the body, side trims:

For example, the side trim mounted on the spoiler above the rear of the car;

and so on, all of which are small enveloping parts, which are characterized by adding to the existing basis, rather than dismantling the original parts and replacing them with new ones.

Large surround (exterior spoiler of the body of the car with a hidden wilderness). The main functions are: 1. Reduce the reverse airflow generated when the car is driving, and increase the downforce of the car at the same time. Makes the car ride smoother, which reduces fuel consumption;

2. High-quality products should be selected. If the envelope material is fragile and the rigidity is too large, it is easy to break, which not only increases the replacement cost, but also adds a lot of trouble;

3. It is best not to choose a large envelope that needs to remove the bumper of the original car to be installed, because the material used in the envelope has poor impact resistance, so the choice of a large envelope that wraps the original bar will not affect the firmness of the vehicle, but if you must choose to dismantle the bumper, the buffer zone in the original bar can be transplanted into the FRP surround to play a protective role;

4. The installation of large surrounds should go to experienced refitting shops, because these refitting shops have the ability to make various surroundings, and most of them will repair the broken stove and surround for the owner for free, so that the owner does not have to spend money to replace a new one for a small damage to the surrounding.

Millions of car purchase subsidies.

Modified cars are surrounded by cars, which is undoubtedly the preference of car enthusiasts. But for some beginners and rookies, it is very likely that they don't know what the car surround is, so let's give you a science score today.

The car is surrounded by a large surrounding, which is actually a spoiler on the outside of the car body, which is divided into two types: pump handle and lip. The encirclement of the pump handle is to remove all the original front and rear left and right bars, and then install another pump handle. The lip bracket is to add half of the lips to the original bumper, but the product quality and assembly and processing technology of this type of bumper are all particularly high regulations, so try to go to a professional modification shop to carry out modification.

For the effect of large encirclement of automobiles, not only can reduce the reverse cyclone formed in automobile driving, but also can improve the downward working pressure of automobiles, so that the stable and safe driving of automobiles has a greater effect, and then enhance the fuel rationality of automobiles.

Is it legal to change the car to a larger encirclement.

For the original modified modified car, it must be legal, because before the first company released the modified module, the modified car materials have already been sent to the vehicle management office, and this kind of modified car is all according to the manufacturer's strict testing. For non-original modifications, under the condition that there is no danger to safe driving and the size of the car body is not changed, the car encirclement is attributed to legitimate personal behavior. Anyone who is cautious and laughs secondly, and any person who has a motor vehicle should apply to the vehicle management office for industrial and commercial change within 10 days after the change, otherwise it will be classified as a disciplinary violation.

What is a cart encirclement? What is a cart encirclement? A lot of people don't know yet. Now let's take a look!

1.The meaning of the car encirclement: in fact, it is the spoiler of the muffled hand outside the body. The encirclement of the cart is a popular name for the collapse of the ant.

2.The main function is to reduce the reverse airflow generated when the car is driving, and increase the downward pressure of the car.

3.Makes the car run more smoothly and thus reduces fuel consumption, which is the domain of aerodynamics.

The so-called enveloping is: front and rear large surround and small surrounding, side skirts, rear wings, etc., and the large envelope is the overall bumper assembly.

It must be registered, but now there are no major accidents in the new car, and there is no need to test the vehicle in the annual review, so the annual review will be considered after 6 years.

The small bumpers are installed on the bumper, similar to the duck lip, or made into the style of the shovel plate, because the past bracket is attached to the original bumper foundation, which plays a beautiful role, adds the effect of large downforce and reduces the drag coefficient.

There are four main materials for the large envelope kit that are more popular in China:

Glass fiber material is poor, such products are the most common, there are many styles to choose from, ** cheaper, but the weight is large and the toughness is not good, and it is easy to break if it is rubbed.

Because ABS plastic products are formed by vacuum blister molding, the thickness is thinner, so this kind of material can not be used as a bumper surrounding, but can only be made into a large encirclement of the lip.

Synthetic resin materials have less shrinkage, good toughness, heat resistance and no deformation, so the surface of the product is smooth and relatively high.

Polyester plastic products are high-pressure injection molding, with high flexibility and strength, high quality, because most of the original bumpers of cars are also made of polyester plastic, the same material, so the fit with the body is also the best, and the life is also longer.

It is recommended that the primary change of the car is: a large 5-piece suit, plus a carbon fiber cover, the rear wing is preferably carbon fiber, I personally prefer fiberglass, aluminum alloy is OK, and you can also add an imitation carbon fiber front cover, which is very cool.

The envelope can be divided into front and rear large surrounds and small envelopes side skirt tail wings, etc., the large envelope is the overall bumper assembly, and the small envelope is installed on the bumper or made into a shovel style, because the past envelope is attached to the original bumper on the basis of increasing downforce and reducing the drag coefficient.

Most cars still consider the installation of large surrounds from the point of view of aesthetics, and to make a real change in aerodynamics, the tail wing (fixed wind wing) plays a great role, and the rear wing is part of the large surrounding.

In fact, the scientific name of the large surround is the body "air spoiler component", which originated in motorsports, and is used to improve the impact of the airflow around the body on the stability of the body in motion, mostly made of carbon fiber, and most of the "large surrounding" in the domestic market does not have this function, but is more designed for aesthetics. The main function of the car surround is to reduce the reverse airflow generated by the car during driving, and can increase the downforce of the car, so that the car can drive more smoothly, so as to reduce fuel consumption. The rear bumper of a car is the enclosure of the rear wing of a car.
