Where are car bumpers and what are the bumpers of a car?

CarsBumpersMost of the materials arePolypropylene plasticIt is mainly located at the front (front bumper) and rear (rear bumper). In addition to maintaining the original protection function, the front and rear bumpers of the car should also pursue harmony and unity with the body shape and the lightweight of themselves. The front bumper of the car is shown in the picture below.

In fact, the early car bumpers were made of steel, and some heavy vehicles and special vehicles have developed today.

Military vehicles still have steel bumpers, while as ordinary passenger cars, the current bumpers are all plastic. As for why the bumper is not made of steel and replaced with plastic, there are mainly the following reasons.

1. In terms of styling, the plastic bumper is very easy to manufacture and the best match with the body, which makes the shape of the car very beautiful. And polypropylene is a very light plastic, which can reduce the weight of the vehicle and thus reduce fuel consumption.

2. Manufacturing cost.

It is relatively low and can reduce the cost of the whole vehicle. On a car body, the front and rear bumpers are the most vulnerable parts of the car. And if the bumper is iron, then it is troublesome to repair, and the correction of sheet metal parts is more complicated than plastic parts.

The bumper of the car is at the head of the car, which is called the front bumper of the car (the piece below the front headlights), and the bumper at the rear of the car is called the rear bumper (the piece under the rear lights).

The car is composed of a lot of precision parts, if the car fails, it is difficult for ordinary car owners to judge whether it is the best problem with the car. Car Keeper hopes to improve the ability of car owners to understand cars and identify car faults through the popularization of car professional knowledge, driving skills and car life knowledge, so as to help car owners better understand their cars and become an excellent car expert.

In this issue, we are the first to know some little knowledge about the bumper.

The car bumper is a safety device that absorbs and slows down the external impact force and protects the front and rear parts of the body. In the past, the front and rear bumpers of automobiles were stamped into channel steel with steel plates, which were riveted or welded together with the frame longitudinal beams. Nowadays, the front and rear bumpers of cars are made of plastic, and the plastic bumpers of general cars are composed of three parts: outer panels, cushioning materials and beams.

Among them, the outer plate and cushioning material are made of plastic, and the beam is stamped into a U-shaped groove with cold-rolled sheet, and the outer plate and cushioning material are attached to the beam, which makes the shape more harmonious and unified with the car body and lighter.

In recent years, a number of news about car bumpers have caused widespread heated discussions, and the masses who do not know the truth have "verbally criticized" the manufacturers, believing that plastic bumpers are not bumped and shoddy. Actually, this is a misunderstanding.

The promotion of plastic bumpers comes from a foreign regulation on automobile safety: the car should be given priority protection to pedestrians in low-speed driving collisions. When traffic accidents occur, pedestrians tend to be vulnerable.

Plastic bumpers can alleviate the impact on pedestrians' legs, especially their lower legs. Over the years, the bumper has formed its current structure, which reduces the level of pedestrian injury in the event of an accident.

Metal becomes plastic, but it is safer! When a plastic bumper encounters an impact, the resulting deformation can absorb a certain amount of collision energy. At the same time, the bumper can distribute the power to the energy absorbing boxes on both sides, then to the left and right front side members, and then to the other structures of the body, and finally to resist by the structural strength of the body.

In addition to the plastic bumper itself, there is also foam padded between the anti-collision steel beam and the bumper. This is not really a "cutting corner", but a cushioning material between the outer panel and the beam. After the addition of foam, the bumper is not easy to break in low-speed collisions, which plays a cushioning role, which not only protects pedestrians, but also reduces the loss of car owners.

Because the foam is not very good for the senses of the Chinese people, some domestic car companies have canceled the foam and replaced it with an energy-absorbing box welded on the anti-collision steel beam. Since the paint color is the same as the steel beams, it looks much "stronger".

In addition to ensuring pedestrian safety, compared with metal bumpers, plastic bumpers also have the advantages of reducing production costs, easy maintenance, and anti-corrosion.

Hello, car bumpers don't include much, so I'll give you a detailed introduction below.

The bumper of the car is mainly the outer part of the outer bar made of plastic, and behind the outer bar is the bumper bracket, which is generally made of iron material that is easy to deform.

At both ends of the bumper are two bumper hangers, in addition to which are some covering parts of the bumper, such as ventilation grilles and traction covers.

The overall structure of the bumper is like this, but when purchasing, there is generally only one outer rod, and the bumper hanger and some covering parts are generally sold separately.

The function of the car bumper is that when the car collides with an obstacle, it can play a cushioning role, which can make a part of the collision force disappear here, which can effectively reduce the loss of the vehicle and ensure the safety of the driver in the cockpit to a certain extent.

Therefore, when choosing a bumper, we must pay attention to ensure the quality of the certificate, otherwise it will bring hidden dangers to life safety and the car.

Many years ago, the front and rear bumpers of automobiles were mainly made of metal materials, and the thickness of steel plates of more than 3 mm was stamped into U-shaped channel steel.

There are only two bumpers in a car, one is the front bumper and the other is the rear bumper. The bumper acts as a collision avoidance. In the event of an accident, it can keep you safe.

Car bumpers include a front bumper and a rear bumper. The car bumper is a safety device that absorbs and slows down the external impact force to prevent the collision of the front and rear of the body, and the front and rear bumpers of the car were once stamped into a channel steel with steel plates and the frame together, and now the bumpers are plastic.

The bumper of the car is surrounded by a plastic shell, and there is a steel beam, which is called the anti-collision steel beam, which is the bumper and the bumper, and there is also an anti-collision steel beam inside the plastic shell.

Aluminum alloy bumper is a tubular bumper made of aluminum alloy, which has the characteristics of many shapes, beautiful appearance, air source, etc., and is mainly stronger than off-road vehicles and small vans.

The bumper of the car is its front bumper, including its impact beam and shell. , are the bumper of the car.

Automobile bumpers are generally divided into front bumper and rear bumper, which can reduce damage to other structures of the body and reduce maintenance costs in the event of a collision.

For example, if the scope of paint scratching is small, there is still no need to paint to solve it, but only need to carry out the corresponding paint repair operation to solve the problem. Let's take a look at how to do it in order to spend the least amount of money to solve the problem of paint scratching.

Method 1: If the degree of scratching is not too serious, and the scratching range is small, there is no need to go to the auto repair shop to repaint, after all, repainting will damage the original paint of the vehicle, which has a great impact on the depreciation of the car. In this case, the owner can buy some small stickers to paste on, after all, the front bumper of the car is mostly made of plastic, even if there is a phenomenon of scratching off the paint, it will not cause rust, etc., so you only need to use a small sticker to cover up the paint scratches.

Method 2: The car bumper is scratched to reveal the black primer, and the scratching will affect the appearance of the car, at this time, a relatively simple method can be taken to solve it. For example, first buy a touch-up paint pen online, then clean the scratched part of the car paint, and after there are no remaining stains and water traces on the surface of the scratching position, finally use the touch-up pen to gently apply the scratched part of the paint, so that the black primer exposed on the scratched part can be covered.

In fact, many of the scratching problems of the body are basically dealt with a touch-up pen, after all, it is economical, and a touch-up paint pen is only a few dollars in cost.

Method 3: When the car bumper is scratched to reveal the black primer, and the car paint scratches a large area and has a certain depth, the owner needs to do a simple paint repair job. For example, you can go online to buy a set of touch-up paint sets, which contain clay, sandpaper, self-spraying paint, etc., and follow the tutorial to operate the touch-up paint **, which can also deal with the exposed parts of the scratch.

Usually a set of paint kits cost about 50 yuan, which is definitely a more economical operation compared with going to the 4S shop to spray paint, you must know that the cost of painting on a side of the 4S shop starts at 150 yuan!

Method 4: When the car bumper is scratched to reveal the black primer, and the scratch is very serious, the vehicle must go to the 4S shop for painting, in fact, the owner can also enjoy the benefits of free painting. For example, when buying insurance for a car, many insurance companies will basically give away 1-2 sides of spray paint, and this paint service is completely free, and more importantly, even if the car owner uses the paint service, it will not be counted into the insurance claim.

Therefore, when there is a scratch on the vehicle and needs to be painted, the owner can take advantage of this opportunity and enjoy the free painting service of the insurance company.
