Summary of the invention
In view of the defect that above-mentioned prior art exists, the purpose of this utility model proposes to be a kind of energy-absorbing assembly of automobile collision preventing crossbeam, and when automobile collides, energy-absorbing effect is good, ensures the safety of passenger.。
The purpose of this utility model, will be achieved by the following technical programs:
For an energy-absorbing assembly for automobile collision preventing crossbeam, it is characterized in that: described energy-absorbing assembly comprises peace
Dress plate and cavity body structure, described adapter plate and the described cavity body structure formula that is formed in one constructs, described cavity body structure is the bevelled cavity body structure of band, the width on described inclined-plane is less than the width of described adapter plate, be provided with one group of energy-absorbing muscle in described cavity body structure, the outside face on described inclined-plane is that face is mated in the welding be connected with collision prevention girders, and the both sides of described adapter plate are respectively equipped with 2 mounting holes, be provided with a hole in the middle of the side of described adapter plate, this hole is used for locating with body structure module pre-installation.
Preferably, described one group of energy-absorbing muscle comprises the first energy-absorbing muscle, the second energy-absorbing muscle and the 3rd energy-absorbing muscle, described energy-absorbing muscle becomes fenestral fabric described cavity body structure parallel divisional, described energy-absorbing muscle is positioned in cavity body structure perpendicular to adapter plate, and described first energy-absorbing muscle is near ramp structure and the thickness of the first energy-absorbing muscle is greater than the second energy-absorbing muscle.
Preferably, the front and back of described cavity body structure are two planes, and described two planes and described adapter plate form a closed cavity body structure.
Preferably, both sides, described inclined-plane respectively have a width is the welding groove of 5mm.
Preferably, the both ends of the surface of described inclined-plane chamber outer surface are the L-type otch of sawing.
The outstanding effect that the utility model has is:
(1) integral structure of energy-absorbing assembly can save an urgent demand that frock expense is also adapted to Modern Automobile Body light-weight design simultaneously, and when automobile collides, energy-absorbing assembly absorbs energy, reduces the injury to occupant;
(2) traditional energy-absorbing assembly due to the too short energy-absorbing effect that causes undesirable; protection to pedestrian when the utility model energy-absorbing assembly had both met automobile low speed collision; and protect vehicle body miscellaneous part; reduce maintenance cost, play the absorption of high-speed crash energy, the power transmission of power protect the effect of occupant simultaneously.
Accompanying drawing explanation
Fig. 1 is the three-dimensional structure diagram of energy-absorbing assembly of the present utility model;
Fig. 2 is the right elevation of the utility model energy-absorbing assembly;
Fig. 3 is the top view of the utility model energy-absorbing assembly;
Fig. 4 is the front elevation of the utility model energy-absorbing assembly.
Detailed description of the invention
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described specifically, is easier to make technical solutions of the utility model understand, grasp:
For an energy-absorbing assembly for automobile collision preventing crossbeam, described energy-absorbing assembly comprises adapter plate 1 and cavity
Structure 2, adapter plate 1 and cavity body structure 2 formula that is formed in one construct, cavity body structure 2 is the bevelled cavity body structure of band, the width on inclined-plane is less than the width of adapter plate, one group of energy-absorbing muscle is provided with in cavity body structure, one group of energy-absorbing muscle comprises the first energy-absorbing muscle 6, second energy-absorbing muscle 7 and the 3rd energy-absorbing muscle 8, energy-absorbing muscle becomes fenestral fabric cavity body structure 2 parallel divisional, energy-absorbing muscle is positioned in cavity body structure 2 perpendicular to adapter plate 1, first energy-absorbing muscle 6 is near ramp structure and the thickness of the first energy-absorbing muscle 6 is greater than the second energy-absorbing muscle 7, the outside face 3 on inclined-plane is that face is mated in the welding be connected with collision prevention girders, this integral type connection mode can make structure compacter, pts wt is lighter, also fusion length can be reduced, it is more reasonable that weld seam is arranged, welding more easily realizes.The both sides of adapter plate are respectively equipped with 2 mounting holes 4, are provided with a hole 5 in the middle of the side of adapter plate, and this hole is used for locating with body structure module pre-installation.The front and back of cavity body structure 2 are two planes, two planes and adapter plate 1 form a closed cavity body structure, the energy-absorbing effect of whole energy-absorbing assembly is made to reach a best state, in order to reduce difficulty of processing and reduce manufacturing cost, weld adopts notching construction design, respectively having a width in both sides, inclined-plane is the welding groove of 5mm, both weldability requirement had been met, the requirement of collision to weld strength can be met simultaneously, the L-type otch 10 of sawing is set in the both ends of the surface of inclined-plane chamber outer surface 3, material and expendable weight can be saved, improve energy-absorbing effect.
