Description
Technical field
The utility model relates to technical field of automobile, particularly a kind of vehicle energy absorption box.
Background technology
Automobile has become the walking-replacing tool of mankind's trip, and substantially increase work and the life efficiency of the mankind, meanwhile, automotive crash safety also more and more comes into one's own.The protective effect of energy absorption ability to passenger inside the vehicle of auto body is also more and more important.The collision performance of automobile is an aspect very important in Integral automobile safety Design.In current automobile design, normally adopt the bumper assembly being arranged on automotive front and afterbody to ensure carriage body construction framework not by havoc under low speed collision, thus ensure the safety of member and car body structure itself in car.In order to absorb the kinetic energy of shock as much as possible, in the design of present bumper assembly, often add a deformation element, i.e. so-called collision energy absorbing box.But the energy-absorption box used now, structure is simple, and energy-absorbing effect is not obvious.
Utility model content
The purpose of this utility model is defect for prior art and deficiency, provides a kind of structure simple, vehicle energy absorption box reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is:
Described in the utility modelly comprise upper shell (1) and lower house (2), lower house (2) one end is closely embedded in the inner chamber of upper shell (1), and described upper shell (1) inner chamber underrun spring (3) is fixedly connected with the inner chamber bottom surface of lower house (2); Described lower house (2) is also closely embedded with EVA lasso (4), and described EVA lasso (4) is arranged between spring (3) and lower house (2) inwall; The lateral wall of described lower house (2) is provided with and connects energy-absorbing bar (5), the top of described connection energy-absorbing bar (5) and the lower edge of upper shell (1) frame are fixedly connected, arrange in gap between described EVA lasso (4) and spring (3), the rectangular shape of cross-sectional plane of EVA lasso (4) lateral wall, the circular in cross-section shape of EVA lasso (4) lateral wall.
Further, described connection energy-absorbing bar (5) is in wave shape.
Further, the cross-sectional plane of described upper shell (1) and lower house (2) all has a rectangular shape
After adopting said structure, the utility model beneficial effect is: a kind of vehicle energy absorption box described in the utility model, comprise upper shell and lower house, lower house one end is closely embedded in the inner chamber of upper shell, and the inner chamber bottom surface of described upper shell inner chamber underrun spring and lower house is fixedly connected; Described lower house is also closely embedded with EVA lasso, and described EVA lasso is arranged between spring and lower house inwall; The lateral wall of described lower house is provided with and connects energy-absorbing bar, and the described top of connection energy-absorbing bar and the lower edge of upper shell frame are fixedly connected.When using the utility model, when upper shell is subject to external impacts, the lower edge of upper shell frame can compress and connect energy-absorbing bar, connects energy-absorbing bar stressed rear by compressive deformation, has now also broken the rigid connection between upper shell and lower house; Energy-absorbing is carried out in upper shell Compress Spring generation elastic deformation, realizes second time energy-absorbing; Meanwhile, the rearward end connecting energy-absorbing bar continues stressed rear by compressive deformation, realizes third time energy-absorbing; Stressed in radial direction of spring can be absorbed by EVA lasso, improve the energy-absorbing effect of spring further; Thus greatly improve the energy absorbing efficiency of energy-absorption box, ensure the safety of occupant.It is simple that the utility model has structure, arranges rationally, the advantages such as cost of manufacture is low.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As Figure 1-3, a kind of vehicle energy absorption box described in the utility model, comprise upper shell 1 and lower house 2, lower house 2 one end is closely embedded in the inner chamber of upper shell 1, and described upper shell 1 inner chamber underrun spring 3 is fixedly connected with the inner chamber bottom surface of lower house 2; Described lower house 2 is also closely embedded with EVA lasso 4, and described EVA lasso 4 is arranged between spring 3 and lower house 2 inwall; The lateral wall of described lower house 2 is provided with and connects energy-absorbing bar 5, and the top of described connection energy-absorbing bar 5 and the lower edge of upper shell 1 frame are fixedly connected; Connecting the lower edge of energy-absorbing bar 5 and upper shell 1 frame through being made of one piece, connecting energy-absorbing bar 5 and being fixedly connected by the lateral wall of glue and lower house 2.
Further, described connection energy-absorbing bar 5 is in wave shape, and this wave shape can play guiding energy-absorbing function, improves energy absorbing efficiency.
Further, the cross-sectional plane of described upper shell 1 and lower house 2 all has a rectangular shape, and improves energy absorbing efficiency.
Further, arrange in gap between described EVA lasso 4 and spring 3, the rectangular shape of cross-sectional plane of EVA lasso 4 lateral wall, the circular in cross-section shape of EVA lasso 4 lateral wall, improve energy absorbing efficiency.
When using the utility model, when upper shell is subject to external impacts, the lower edge of upper shell frame can compress and connect energy-absorbing bar, connects energy-absorbing bar stressed rear by compressive deformation, has now also broken the rigid connection between upper shell and lower house; Energy-absorbing is carried out in upper shell Compress Spring generation elastic deformation, realizes second time energy-absorbing; Meanwhile, the rearward end connecting energy-absorbing bar continues stressed rear by compressive deformation, realizes third time energy-absorbing; Stressed in radial direction of spring can be absorbed by EVA lasso, improve the energy-absorbing effect of spring further; Thus greatly improve the energy absorbing efficiency of energy-absorption box, ensure the safety of occupant.In addition, this structure is simple, reasonable in design, low cost of manufacture.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
