Specific embodiment
In order that those skilled in the art more fully understands technical scheme, below in conjunction with accompanying drawing to this
Bright it is further detailed.
Referring to shown in Fig. 3 and Fig. 4, being a kind of vehicle rear protecting provided in an embodiment of the present invention, it is arranged on chassis runner
Afterbody, including rear bumper 1, it plays the effect of protection vehicle tail.
Rear-swing arm 2, one end of rear-swing arm 2 is rotatedly connected with chassis runner 3, and the other end is rotated with rear bumper 1 and is connected；?
The stopping means limiting rear-swing arm 2 rotational angle are additionally provided with chassis runner 3.
And secondary swing arm 2, one end of secondary swing arm 2 rotated with chassis runner 3 and is connected, and the other end is connected with rear bumper 1 rotation
Connect.
In the present embodiment, rear-swing arm 2, secondary swing arm 4 and chassis runner 3 surround a triangle, the base angle of triangle be with after
, that is to say, that the two ends of triangle are connected with chassis runner 3, its other end can be with regard to for the movable end that bumper 1 is connected
Chassis runner 3 moves up and down, thus driving rear bumper 1 to move up and down.Achieve the adjustable for height function of rear bumper 1, when
Need by property stronger when, raise rear bumper upwards, improve its departure angle, then pass through the locked fixation of stopping means.And
During its normally travel, reduce rear bumper height, thus reducing its crumple zones, it is to avoid dolly tailing edge crumple zones of knocking into the back pierce vehicle
Bottom.
Wherein, stopping means can be threaded rod and nut screw connection form, namely threaded rod is fixed on longeron, its one end with
Rear-swing arm is rotatedly connected, its angle adjustment pass through rotate rear-swing arm realize, its spacing by tighten nut realize.But this mode,
Not easy to operate, need to artificially adjust realization.In the present embodiment, as shown in Fig. 3 to Fig. 4, stopping means include torsion-bar spring 5 and pedestal
6；Wherein, pedestal 6 is fixed on body bottom, and pedestal 6 specifically includes, the installing plate 61 at top and the fixed cover 62 at middle part；Install
Plate 61 is welded on longeron, and the middle part of torsion-bar spring 5 is fixedly connected with pedestal 6, and the present embodiment is, fixed cover 62 and torsion-bar spring
5 middle part interference connects.The two ends of torsion-bar spring 5 are rotated with rear-swing arm 2 after stretching out chassis runner 3 respectively and are connected.It is, turning round
It is actually the adjustment area of torsion-bar spring, torsion-bar spring adjusts area by this section, can carry out between the middle part of bar spring 5 and end
Certain torsional deformation, thus when rear bumper is with bar contact, rear bumper can automatically carry out small upper shifting or decline,
Rear bumper 1 can pass through the swing of torsion-bar spring 5, thus ensureing by property it is ensured that passing through can avoid when obstacle, with
When, torsion-bar spring 5 plays buffering impact stresses effect.
In conjunction with shown in Fig. 4 and Fig. 6, in order to realize the departure angle adjust automatically of rear bumper further, thus realizing vehicle
During with bar contact, it realizes the automatic lifting of departure angle by self structure.In the present embodiment, vertical in rear bumper direction
One side bottom of beam is fixed with a roller 7 along rear bumper length direction, secondary swing arm 4 and rear-swing arm 2 pass through respectively roller 7 with after
Bumper 1 is rotatedly connected, and the bottom acting surface of roller 7 extends downwardly from rear bumper 1, so that it is guaranteed that it can be connect with barrier at first
Touch, roller realizes the contact guiding with barrier.
As shown in Figure 1 and Figure 5, the device of this programme not only can adjust up and down to improve departure angle, also can adjust in front and back meanwhile
Whole, it is specially and opens up a gathering sill 8 in the bottom surface of chassis runner 3 along chassis runner length direction；The bottom setting of gathering sill 8
One slide block 9；The top of gathering sill 8 arranges a cover plate 11；Cover plate 11 is connected by attachment screw with slide block 10, attachment screw 11 according to
Secondary be connected with slide block 9 through after cover plate 10, gathering sill 8, thus realizing the connection of slide block and cover plate, and slide block is fixed on guiding
At groove 8；Slide block 9 is rotated with secondary swing arm and is connected.During use, slide block 9 can move forward and backward along gathering sill 8, and then dolly is knocked into the back
When, secondary swing arm 4 can have certain decrement in x direction, thus, secondary swing arm 4 acts on rear-swing arm 2, and then acts on torsion-bar spring 5,
And by the deformation of torsion-bar spring 5, reduce the energy impact in knockout process.
When rear body stroke speed is larger, when torsion-bar spring deformation is not enough to offset Vehicular impact energy, the present embodiment
Further with improvement, it also can be offset by secondary swing arm 4 deformation, and middle part in this programme for the secondary swing arm 4 is towards longeron side
The buffer part 41 of bending；When vehicle is bumped against with rear bumper, buffer part 41 gradually straightens, and plays the effect of buffering impact force,
Can be found in the process of Fig. 7 to Fig. 8.It is further preferred that buffer part 41 is provided with breach 42 towards the side of longeron.Due to breach 42
Place is more weak, vehicle forward when, torsion-bar spring 5 is rotated down, and secondary swing arm 4 is gradually straightened, and to offset part by deformation
Rear body clashes into.It is additionally provided with a supporting part 43 in secondary swing arm 4 towards the side of rear bumper, supporting part 43 is located at kink
Bottom side, the end of supporting part 43 is contacted with the middle part of rear bumper 1.The design of supporting part 43 is equivalent to and gives secondary swing arm bottom side
One fulcrum, so that secondary swing arm is when being impacted power deformation, does not produce excessive interference with rear bumper arm, to affect rear bumper
Use.Wherein, secondary swing arm 4 is made preferably by casting integrated molding in processing.
In sum, this device using secondary swing arm, swing arm special construction it is ensured that the vehicle rear bumper road clearance less
While it is ensured that departure angle sufficiently large it is ensured that trafficability；Meanwhile, using torsion-bar spring spring, and part distortion is come
Offset Vehicular impact energy, protect rear car.
The above some one exemplary embodiment only describing the present invention by way of explanation, undoubtedly, for ability
The those of ordinary skill in domain, in the case of without departing from the spirit and scope of the present invention, can by with various different in the way of to institute
The embodiment of description is modified.Therefore, above-mentioned accompanying drawing and description are inherently illustrative, should not be construed as to the present invention
The restriction of claims.
