Description
Technical field
The utility model automobile buffer beam, belongs to automotive body structure technical field, particularly a kind of collision prevention girders structure of automobile.
Background technology
Along with the raising day by day of people's living standard, the owning amount of automobile gets more and more, automobile popularize to people's life bring many simultaneously easily, also make traffic accident constantly increase, traffic accident has brought shade.In order to improve the safety of automobile, alleviate the harm that traffic accident brings, automobile generally can install anticollision device, however existing anticollision device complex structure, inconvenience install, add the use cost of automobile.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical matters to be solved is to provide a kind of automobile buffer beam, and structure is simple, and good buffer effect, improve safety guard-safeguard performance, and self-reparability is strong.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: automobile buffer beam, comprise cross member of frame, buffer beam and recovery beam, the both sides, front end of cross member of frame are respectively equipped with a guide frame, the buffer beam of arc is arranged on the front of cross member of frame and its two ends are each passed through two guide frames to the protection of car body formation arc, recovering the structure of beam is that two beam slabs have one end to be fixed on cross member of frame front end to form arch and the other end of two beam slabs is connected and fixed by recovery spring respectively, recover beam to contact with buffer beam between cross member of frame with buffer beam.
Described buffer beam with recover beam two beam slab contact surfaces on be equipped with guide and limit groove, two beam slabs are equipped with an orienting lug and orienting lug coordinate be arranged in corresponding guide and limit groove, the cross-sectional plane of described guide and limit groove and orienting lug is T-shaped.
Described guide frame is coated with rubber pad.
Described buffer beam and recovery beam are alloy material and make.
The utility model compared with the existing technology has following beneficial effect.
1, the utility model is using buffer beam as energy-absorbing beam, rely on the distortion of buffer beam, recover the kinetic energy absorption of spring and the Relative friction consumption between buffer beam and recovery beam, impulsive contact force is carried out dispersion release, structure is simple, easy to use, safety performance is high, after impulsive contact force consumes completely, is recovering to make recovery beam and buffer beam all return to initial condition under the recovery action of the spring on beam.
2, the utility model arranges ways between buffer beam and beam slab, the mutual motion that can ensure buffer beam on the one hand and recover between beam, and another conveniently can also pray position-limiting action makes buffer beam not depart from or depart from guide frame.
3, guide frame of the present utility model installs rubber pad, can the collision bumping against guide frame position be protected equally.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the mounting structure schematic diagram of guide and limit groove and orienting lug in the utility model.
Fig. 3 is the distortion schematic diagram after the utility model is clashed into.
In figure: 1 is cross member of frame, 2 is buffer beam, and 3 is guide frame, and 4 is beam slab, and 5 for recovering spring, and 6 is guide and limit groove, and 7 is orienting lug.
Detailed description of the invention
As shown in Figure 1-2, the utility model automobile buffer beam, comprise cross member of frame 1, buffer beam 2 and recover beam, the both sides, front end of cross member of frame 1 are respectively equipped with a guide frame 3, the buffer beam 2 of arc is arranged on the front of cross member of frame 1 and its two ends are each passed through the protection of two guide frames, 3 pairs of car bodies formation arcs, to recover the structure of beam be that two beam slabs 4 have one end to be fixed on cross member of frame 1 front end to form arch and the other end of two beam slabs 4 is connected and fixed by recovering spring 5 respectively, recovers beam and contact with buffer beam 2 with between buffer beam at cross member of frame 1.
Described buffer beam 2 and two beam slab 4 contact surfaces of recovery beam are equipped with guide and limit groove 6, two beam slabs 4 are equipped with an orienting lug 7 and orienting lug 7 coordinate be arranged in corresponding guide and limit groove 6, the cross-sectional plane of described guide and limit groove 6 and orienting lug 7 is T-shaped.
Described guide frame 3 is coated with rubber pad.
Described buffer beam 2 and recovery beam are alloy material and make.
Working process
As shown in Figure 3, when having vehicle or other objects to hit car body front end, buffer beam 2 bends because receiving the pressure from front, and two ends move hold-off pressure by guide frame 3 to car body rear, beam slab 4 is compressed in simultaneous buffering beam 2 deformation process, two beam slabs 4 are out of shape equally and compress middle recovery spring 5 energy-absorbing, counter motion friction force between buffer beam 2 and beam slab 4 also counteracts a part of impulsive contact force, impulsive contact force dissipates in many ways, protecting car body better makes it not damaged by directly clashing into, and safety performance is high and structure is simple;
After leaving collision object, under the effect recovering spring 5, two beam slabs 4 are softened, make the buffer beam 2 pages be in contact with it restPose simultaneously;
Buffer beam 2 and two beam slab 4 contact surfaces of recovery beam are equipped with a bit of guide and limit groove 6, and coordinate with the orienting lug 7 on beam slab 4 and install, make it in collision or rejuvenation, not depart from original position or directly depart from guide frame 3 and drop from cross member of frame 1.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from the utility model aim.
