Description

A plastic car bumper with an airbag

technical field

The utility model relates to an automobile bumper, in particular to a plastic automobile bumper with a safety air bag, which belongs to the technical field of automobile equipment.

Background technique

With the rapid development of the economy, the popularity of automobiles is getting higher and higher, and the traffic accidents that follow are also increasing day by day, causing considerable economic losses and casualties. Generally speaking, in order to reduce the damage to the vehicle due to car collision or the occurrence of safety accidents, and reduce the damage to cars and people, bumpers are provided at the front and rear ends of the car. However, for most trucks, because of their structure Therefore, there is no bumper at the back of the large truck. Although some bumpers are also installed at the rear of the car, the installation position is too high to protect it in practical applications. At present, many traffic accidents are caused by rear-end collisions between small cars and big cars, and the small car hits the big car. Because the big car is not equipped with a rear bumper, it is very easy to cause casualties, because the tail of the truck is high and far from the rear wheels. Long distance, therefore, dolly just gets into the afterbody of truck once rear-end collision, and its rear cross bar just directly extrudes the personnel who sits in the front row of dolly, causing casualties. In summary, the utility model adopts that a rear bumper is arranged at the rear end of the car body of a large truck, and a buffer device is arranged in the rear bumper, and the height of the rear bumper corresponds to the height of a small car. Therefore, when When a small car collides with a large truck, the rear bumper of the large truck can play a buffer role. At the same time, when the impact force is large, the airbag pops up, which can greatly reduce the damage of the small car, thereby reducing casualties , to reduce the losses caused by traffic accidents, for this reason, we propose a plastic car bumper with airbags.

Utility model content

The technical problem to be solved by the utility model overcomes the existing defects, and provides a plastic automobile bumper with an airbag. A rear bumper is arranged at the rear end of the car body of a large truck, and a buffer is arranged in the rear bumper. device, and the height of the rear bumper corresponds to the height of the small car. Therefore, when the small car collides with the large truck, the rear bumper of the large truck can play a buffer role. At the same time, when the impact force is large, The ejection of the safety airbag can greatly reduce the damage of the car, thereby reducing casualties, reducing losses caused by traffic accidents, and can effectively solve the problems in the background technology.

In order to solve the above technical problems, the utility model provides the following technical solutions:

The utility model provides a plastic automobile bumper with a safety airbag, which comprises a bumper body. The bumper body includes a plastic shell, a buffer device, a mounting frame and an airbag. The ribs and the plastic shell are integrally formed, and both ends of the plastic shell are fixedly connected with the installation frame. The installation frame is provided with an inflatable device, and one side of the inflatable device is provided with an airbag groove, and the airbag groove is provided with an airbag inside. The plastic shell is connected with the installation frame through a buffer device.

As a preferred technical solution of the utility model, the number of the inflatable device, the airbag groove and the airbag is at least two.

As a preferred technical solution of the present utility model, the buffer device is a spring or a shrapnel, and there are at least five buffer devices.

As a preferred technical solution of the present invention, the reinforcing ribs are arranged on one side of the plastic shell in an irregular shape and are made of plastic material.

As a preferred technical solution of the present invention, a fixing piece is provided on one side of the installation frame, and the height of the lower surface of the installation frame from the ground is 0.2m-0.7m.

The beneficial effects achieved by the utility model are as follows: a plastic automobile bumper with an airbag adopts a rear bumper arranged at the rear end of the car body of a large truck, a buffer device is arranged in the rear bumper, and the rear bumper The height of the bar corresponds to the height of the small car, so when the small car collides with the large truck, the rear bumper of the large truck can play a buffer role, and at the same time, when the impact force is large, the airbag pops up, which can Reduce the damage of the car to a large extent, thereby reducing casualties and reducing losses caused by traffic accidents.
