Anti-collision device and method for making rubber block of anti-collision device

Abstract

The present invention provides an anti-collision device. The anti-collision device comprises a casing body and one or more than one rubber block(s); wherein, the casing body comprises a bearing cap and one or more than one nested cylinder(s), the inside of which forms a hollow space; the rubber block(s) is / are hollow rubber block(s) and is / are filled in the hollow space. The present invention simultaneously discloses a manufacturing method of the rubber block used in the anti-collision device. Because the present invention adopts a damping structure with one or more than one nested cylinder(s) and the rubber ball(s) is / are filled in the structure, the anti-collision device has excellent anti-collision performance, and the rubber ball(s) filled in the anti-collision device can be replaced, which ensures the performance of the anti-collision device and simultaneously saves the costs.

Description

technical field [0001] The invention relates to an anti-collision device. Background technique [0002] With the increase of the amount of cars, car collision accidents often occur. Although there are bumpers, because the bumpers are rigid, when the collision force is large, not only the bumper and the shape of the car are easily damaged, but also the personnel on the car will be damaged. easy to get injured. In view of the shortcomings of this rigid bumper, there is also a spring steel plate anti-collision device in the prior art. The anti-collision device is composed of multi-layer symmetrical spring steel plates arranged step by step. The other end is a curved shock-absorbing contact, the outermost shock-absorbing contact is fixed on the liner, and a spring is installed in the cavity formed by the liner and the spring steel plate, which can cushion the collision when the car collides. However, the buffer force of this anti-collision device is too small, and the possibil...

[0002] With the increase of the amount of cars, car collision accidents often occur. Although there are bumpers, because the bumpers are rigid, when the collision force is large, not only the bumper and the shape of the car are easily damaged, but also the personnel on the car will be damaged. easy to get injured

In view of the shortcomings of this rigid bumper, there is also a spring steel plate anti-collision device in the prior art. The anti-collision device is composed of multi-layer symmetrical spring steel plates arranged step by step. The other end is a curved shock-absorbing contact, the outermost shock-absorbing contact is fixed on the liner, and a spring is installed in the cavity formed by the liner and the spring steel plate, which can cushion the collision when the car collides. However, the buffer force of this anti-collision device is too small, and the possibility of driver injury after the collision of the car body is still very high, and this anti-collision device is not easy to repair after damage, and can only be replaced with a new anti-collision device. device
