Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0016] Such as figure 1 , figure 2 and image 3 As shown, the present invention is made of parts such as car door outer panel 1, reinforcing plate 2, car door inner panel 3, buffer block 4, cover plate 5 and positioning column 6. The reinforcing plate 2 is located between the outer door panel 1 and the inner door panel 3, and the structure and connection relationship of the three are the same as those in the prior art, and will not be repeated here. A buffer block 4 is fixed on the surface of the door inner panel 3 facing the door outer panel 2 , and the buffer block 4 is located in the cavity of the reinforcing plate 2 . The buffer block 4 is composed of a mounting seat 4a and a boss 4b. The inner end of the boss 4b is integrated with the mounting seat 4a, and a step is formed between the boss 4b and the mounting seat 4a. The step is connected to the doo...

Abstract

The invention discloses a car side-collision prevention device. A reinforcing plate (2) is arranged between a door outer plate (1) and a door inner plate (3); and a buffer block (4) is fixedly arranged on the door inner plate (3) and is located in a cavity of the reinforcing plate (2). The end surface (facing the door outer plate (1)) of the buffer block (4) is covered with a cover plate (5), and the cover plate (5) is fixed with the buffer block (5). According to the car side-collision prevention device, by additionally arranged a cover plate to the end surface (facing the door outer plate) of the buffer block, the buffer block can be uniformly stressed through the cover plate when being impacted, and thus the breakage of the buffer block is avoided, the protection capacity of the buffer block is improved, and the waist of a passenger directly opposite to the buffer block is effectively protected; and moreover, the device disclosed by the invention has the characteristics of skillful design, simple structure, obvious protection effect and the like, and is easy to transform and low in cost.

Description

technical field [0001] The invention belongs to the technical field of cars, and in particular relates to a device for preventing side collisions of cars. Background technique [0002] At present, the car door of a car is usually composed of a door outer panel, a car door inner panel and a reinforcing plate, and the reinforcing plate is located between the car door outer panel and the car door inner panel. The position where the reinforcement plate faces the occupant's waist is generally hollowed out to facilitate the installation of the window regulator. However, when this position is hit, the outer panel of the door will deform inward, which is likely to cause injury to the occupants. For this reason, some cars are provided with a buffer block of plastic material at the hollowed-out position of the door reinforcement plate to buffer the side impact, thereby protecting the waist of the occupant in the car. However, when the force on the buffer block is uneven, the buffer b...
