Description

Automobile buffer block structure

Technical Field

The utility model belongs to the technical field of automobile parts, a car buffer block structure is related to.

Background

At present, the number of automobiles is increasing in China, and competition of various manufacturers is also intensified. According to market requirements, various manufacturers continuously improve their own technologies, enhance their own core competitiveness, and ensure that they are in a safe position in intense competition and are not eliminated by the market.

For example, the conventional bumper block installed behind the bumper of the automobile is mostly made of EPP materials, the bumper block is hard and solid inside, as shown in FIG. 1, the bumper block has small deformation, and once the automobile collides, the bumper block is easily damaged.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an automobile buffer block structure for overcoming the defects of the prior art.

The purpose of the utility model can be realized through the following technical scheme:

the utility model provides an automobile buffer block structure, is in including demountable installation buffer support on crashproof roof beam before the car and with parallel arrangement a plurality of bow-shaped buffering elastic rods that are of buffer support front end surface.

Furthermore, the buffering support and the buffering elastic rod are integrally formed in an injection molding mode.

Furthermore, the buffering elastic rod comprises a first buffering rod and a second buffering rod which are transversely and sequentially arranged along the buffering support, wherein the vertical height of the second buffering rod on the buffering support is lower than that of the first buffering rod.

Furthermore, the height difference and the deformation capacity of the first buffer rod and the second buffer rod meet the following requirements: the height of the second buffer rod when the second buffer rod is not stressed is higher than that of the first buffer rod when the first buffer rod is compressed and deformed to the maximum value by the vertical force along the buffer bracket.

Furthermore, the buffering elastic rod positioned at the outermost ends of the two sides of the buffering support is a first buffering rod.

Furthermore, the rear end surface of the buffer support is provided with a plurality of clamping blocks which are clamped with the front anti-collision beam of the automobile.

Furthermore, a screw column which can be fixed with the front anti-collision beam of the automobile through a screw structure is further arranged on the buffer support.

Furthermore, the buffer support is of a square frame structure with grids.

Compared with the prior art, the utility model has the advantages of it is following:

(1) compare in traditional solid EPP buffer block, the utility model discloses a buffering main part is bow-shaped buffering elastic rod for being, and it can adopt material injection moulding such as PP. When the automobile collides and the bumper deforms towards the rear of the automobile to extrude the buffer block, the collision impact force can be well buffered and released, and the impact on passengers and pedestrians is relieved.

(2) The buffering main part divide into the two-stage, and as the first buffer beam of first level to and as the first buffer beam + second buffer beam of second level, can effectively be suitable for different collision circumstances through the two-stage buffering, improve buffering effect, simultaneously, also reduced the fragile risk of single-stage form's buffer structure.

(3) The whole buffer block structure is light in weight and convenient to disassemble and assemble.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Example 1:

the structure of the automobile buffer block is shown in figure 2, and the automobile buffer block structure comprises a buffer support 3 which is detachably mounted on a front anti-collision beam of an automobile, and a plurality of arched buffer elastic rods 4 which are arranged on the front end surface of the buffer support 3 in parallel. The buffer bracket 3 and the buffer elastic rod 4 are formed into a whole by injection molding.

Referring to fig. 2 again, the rear end surface of the buffer bracket 3 is provided with a plurality of clamping blocks 2 which are clamped with the front anti-collision beam of the automobile. And the buffer bracket 3 is also provided with a screw column 1 which can be fixed with the front anti-collision beam of the automobile through a screw structure. The buffer support 3 is in a square frame structure with grids.

Example 2

On the basis of embodiment 1, the present embodiment further adopts the following design:

referring to fig. 3, the buffering elastic rod 4 includes a first buffering rod 5 and a second buffering rod 6 arranged in sequence along the horizontal direction of the buffering bracket 3, wherein the vertical height of the second buffering rod 6 on the buffering bracket 3 is lower than that of the first buffering rod 5. The difference in height and the deformability of first buffer beam 5 and second buffer beam 6 satisfy: the height of the second buffer rod 6 when not stressed is higher than that of the first buffer rod 5 when the first buffer rod is compressed and deformed by the vertical force along the buffer bracket 3 to the maximum value. The buffer elastic rod 4 positioned at the outermost end of the two sides of the buffer bracket 3 is a first buffer rod 5.

In the above embodiments, unless otherwise specified, all the component structures used are conventional structures in the art for achieving the functions thereof.

The embodiments described above are intended to facilitate the understanding and use of the invention by those skilled in the art. It will be readily apparent to those skilled in the art that various modifications to these embodiments may be made, and the generic principles described herein may be applied to other embodiments without the use of the inventive faculty. Therefore, the present invention is not limited to the above embodiments, and those skilled in the art should make improvements and modifications within the scope of the present invention according to the disclosure of the present invention.
