Abstract
The invention relates to an anti-collision energy-absorbing collapse box for a car, which comprises a bigger collapse case having an annular structure and a smaller collapse case arranged in the bigger collapse case, wherein the smaller collapse case comprises a solid structural case with an end face in an annular, round, rectangular or irregular shape; at least one layer of the annular collapse case is arranged between the bigger collapse case and the smaller collapse case; and the heights of collapse cases are different. Compared with the prior art, the anti-collision energy-absorbing collapse box for a car has better buffering and energy-absorbing functions, can be singly arranged in the car door or other parts of the car body, also can be combined with front and back fender-guards of the car, and can obviously enhance the buffering and energy-absorbing effects. An annular collapse box which is made of metal materials and has flexibility and a columnar or spherical collapse box made of fragile materials have better buffering and energy-absorbing functions in the collision process. The combined collapse box can further increase the energy-absorbing effect in a limited space, so as to more efficiently protect the passengers in the car.
Description
Technical field
The present invention relates to the anti-collision energy absorption device, especially a kind of anti-collision energy absorption crumple box that is mainly used in as automobile safety protector.
Background technology
On March 5th, 2008, Chinese patent CN101134451A discloses " bumper of vehicles " of Japanese Mazda Representative Office application, wherein relate to a pair of crumple box that is installed on the center beam of bumper, its complex structure produces crumple in collision to a certain degree, the volume of crumple box is bigger, its installation site also is subjected to certain restriction, length direction at automobile has taken available space, and the crumple process certainly will cause damage to other member of automobile, and maintenance and replacement cost are bigger.Studies show that the crumple box that adopts metallic material with certain flexibility to make has buffer action preferably in collision process, the crumple box that adopts hard brittle material to make has cracked preferably energy-absorbing function in collision process.
Summary of the invention
At the deficiency of above existing crumple box, the purpose of this invention is to provide a kind of anti-collision energy absorption crumple box with better buffering and energy-absorbing function, can in finite space, further improve buffering and energy-absorbing effect.
The objective of the invention is by realizing by the following technical solutions:
Automobile collision preventing energy-absorbing crumple box, it comprises the big crumple box that is made as loop configuration and is located at than the less crumple box among the big crumple box;
Described less crumple box comprises that end face is annular, circle, rectangle or erose spatial structure box body.
As the preferred technical solution of the present invention, also be provided with one deck annular crumple box at least between described bigger annular crumple box and the described less crumple box.
As the preferred technical solution of the present invention, each is unequal for the height of described every layer of annular crumple box, and every layer of annular crumple box interconnects with being located at middle minimum crumple box, thereby constitutes integral structure.
As the preferred technical solution of the present invention, the height of described big crumple box is greater than the height of adjacent less crumple box.
As the preferred technical solution of the present invention, the different component parts of described crumple box adopt different materials to make, be arranged on outer field annular crumple box and made by the metallic material with certain flexibility, the crumple box that is arranged on internal layer is made by easily cracked non-metallic material or metallic material.
As the preferred technical solution of the present invention, described crumple box is made enclosed construction by metallic material, and crumple box inside is filled with the gas of certain pressure.
The invention has the beneficial effects as follows: with respect to prior art, the present invention has buffering and energy-absorbing function preferably, can be arranged in the arrangements for automotive doors separately and other position of vehicle body, also can be used in combination, can significantly strengthen buffering and energy-absorbing effect with the front and back bumper/spoiler of vehicle.
The compound type crumple box of making by different materials, the metallic material that employing has a certain flexibility is made and is arranged on outer field annular crumple box, adopt hard brittle material to make and be arranged on middle cylindricality or spherical crumple box, can in collision process, bring into play better buffering and energy-absorbing function.Compound type crumple box can further improve buffering and energy-absorbing effect in finite space, be specially adapted to dilly, thereby can protect the occupant in the vehicle more effectively in collision case.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the center sectional structure scheme drawing of Fig. 1.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing and specific embodiment:
The present invention relates to automobile collision preventing energy-absorbing crumple box, it comprises the big crumple box that is made as loop configuration and is located at than the less crumple box among the big crumple box; Described less crumple box comprises that end face is annular, circle, rectangle or erose spatial structure box body.
As depicted in figs. 1 and 2, in the present embodiment, also be provided with one deck intermediate annular crumple box 62 between described bigger annular crumple box 61 and the less crumple box 63.And each is unequal for the height of every layer of annular crumple box, the height of annular crumple box 61 is greater than the height of annular crumple box 62, the height of annular crumple box 62 is greater than the height of cylindricality crumple box 63, annular crumple box 61,62 interconnects with the bottom of crumple box 63 in the middle of being located at, thus the formation integral structure.
Present embodiment annular crumple box 61 and annular crumple box 62 are to be made by metallic material, and intermediate cylindrical crumple box 63 is to be made by easily cracked metal or non-metallic material, thereby constitute compound type anti-collision energy absorption crumple box.
In order further to improve energy-absorbing effect in the limited installing space of automobile, the crumple box adopts enclosed construction.Described annular crumple box 61,62 and cylindricality crumple box 63 are all made enclosed construction, and crumple box inside is filled with the gas greater than bar pressure, to bring into play the crumple energy-absorbing function to greatest extent in collision process.
Crumple box of the present invention can be installed in the position, front and back of auto body, is arranged in the car door and the side of vehicle body, can also carry out aggregate erection with the front and back bumper/spoiler of vehicle.Particularly, can in collision case, significantly strengthen buffering and energy-absorbing effect, thereby protect the occupant in the vehicle more effectively for dilly.
