Description

Automobile rubber bumper

Technical field

The utility model relates to bumper technical field, especially a kind of automobile rubber bumper.

Background technique

Automotive front end is equipped with bumper, not only has decoration functions, it is often more important that can play absorption and buffering is extraneous Impact force protects vehicle body and protects the effect of passenger safety, and it is passenger that the quality of bumper, which directly influences the safety of automobile, The one of personal safety is umbrella, therefore, weight of the research and development of new automobile rubber front bumper by more and more researchers Depending on plastic material or aluminum alloy materials are usually used in the outside of existing automobile front beam, and lack phase in bumper The buffer unit answered, bumper and when car body collision, since plastics and aluminum alloy materials are rigidly stronger, and lack buffer unit into Row buffering, so that car body and bumper are easy to be damaged.

Summary of the invention

The purpose of this utility model is: overcoming deficiency in the prior art, providing a kind of inside has buffer unit, uses The automobile rubber bumper of service life length.

In order to solve the above technical problems, the technical solution adopted in the utility model is as follows:

A kind of automobile rubber bumper, including anti-collision beam have buffer unit, the buffering on the inside of the anti-collision beam Component includes preceding buffer bar and rear buffer bar, is connected between preceding buffer bar and rear buffer bar by bumper post, is opened on preceding buffer bar There is the hole to match with bumper post, be connected through a screw thread between bumper post and rear buffer bar, has a circle compressed spring outside bumper post, The inside edge of the anti-collision beam has mounting plate for one week, and mounting hole is provided on the mounting plate, and the surface of the mounting plate has One layer of cushion.

Preferably, there is energy-absorption box on the inside of the anti-collision beam.

Preferably, several energy-absorbing balls are filled in the energy-absorption box, the diameter of the energy-absorbing ball is different, the energy-absorbing There is one layer of magnet in the outer surface of box.

Preferably, it is bolted between the anti-collision beam and preceding buffer bar, has on the inner wall of the anti-collision beam The bolt hole being connected with preceding buffer bar.

Preferably, the compressed spring is damping compressed spring.

Preferably, the bumper post is the solid bumper post of rubber bodies.

Preferably, there is a circle rubber protective layer on the outside of the compressed spring.

Preferably, there is reinforcing rib on the outside of the rubber protective layer, the reinforcing rib is S-type to be wrapped in rubber protective layer On outer surface.

It is using the beneficial effect of the technical solution of the utility model:

1, the automobile rubber bumper of the utility model passes through energy-absorption box and dual buffer structure in slight impact Bumper and absorbing shock protective effect can be achieved, can avoid bumper housing deformed damaged；

2, there is energy-absorption box in the utility model on the inside of anti-collision beam, the structure design of energy-absorption box improves rubber insurance Thick stick is to the absorbability of noise and other impact forces, when automobile collides, since integrally absorbable energy significantly increases bumper Add, lesser deformation occurs for the other component of automobile, the hologenetic deformation of automobile is small can guarantee passenger compartment do not occur compared with Large deformation and jeopardize passenger safety.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.

Fig. 1 is the structural schematic diagram of the utility model.

In figure: 1 anti-collision beam, buffer bar before 2-1, buffer bar after 2-2,3 bumper posts, 4 compressed springs, 5 mounting plates, 6 is slow Punching pad, 7 energy-absorption boxes.

Specific embodiment

The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram, Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.

As shown in Figure 1, there are buffer unit in a kind of automobile rubber bumper, including anti-collision beam 1, the inside of anti-collision beam 1, Buffer unit improves the cushion performance of bumper, to improve the safety in utilization of bumper, buffer unit includes preceding slow Jumper bar 2-1 and rear buffer bar 2-2, using this structure so that buffer unit has a dual buffer function, preceding buffer bar 2-1 and Connected between buffer bar 2-2 by bumper post afterwards, be provided with the hole to match with bumper post 3 on preceding buffer bar 2-1, bumper post 3 with It is connected through a screw thread between buffer bar 2-2 afterwards, has a circle compressed spring 4 outside bumper post 3, compressed spring 4 further improves rubber The inside edge of the cushion performance of glue bumper, anti-collision beam 1 has mounting plate 6 for one week, and mounting hole is provided on mounting plate 6, uses This structure, installing and dismounting is more convenient, and there is one layer of cushion 6 on the surface of mounting plate 6, and the structure design of cushion 6 further increases The cushion performance of rubber bumper, improves the safety in utilization of bumper.

There is energy-absorption box 7 in the inside of anti-collision beam 1 in the present embodiment, and the structure design of energy-absorption box 7 improves rubber bumper To the absorbability of noise and other impact forces, when automobile collides, since integrally absorbable energy dramatically increases bumper, Lesser deformation occurs for the other component of automobile, the hologenetic deformation of automobile is small can guarantee passenger compartment larger change does not occur Shape and jeopardize passenger safety.

Several energy-absorbing balls are filled in the present embodiment in energy-absorption box 7, the diameter of energy-absorbing ball is different, outside energy-absorption box 7 There is one layer of magnet on surface, and using this structure, the absorbable energy of energy-absorption box 7 is dramatically increased, when automobile collides, due to insurance Integrally absorbable energy dramatically increases thick stick, and lesser deformation occurs for the other component of automobile, and the hologenetic deformation of automobile is small It can guarantee moderate finite deformation not occurring and jeopardizing passenger safety for passenger compartment.
