The specific embodiment
Consult Fig. 1, Fig. 2 and in conjunction with Fig. 4, Fig. 5, the rear bumper 1 of vehicle comprises that two longerons 11, are connected tail lamp bracket 12 on two longerons 11 is connected two longerons 11 with one crossbeam 13.One end of two longerons 11 is respectively hinged with chassis of vehicle 2 by a jointed shaft 111, and the other end of two longerons 11 is connected with crossbeam 13, and tail lamp bracket 12 is welded on the middle part of two longerons 11.Two longerons 11 can rotate with respect to jointed shaft 111 together with its entablatrance 13 and tail lamp bracket 12, underframe 2 is provided with a limes superiors hole and limiting orifice once, and longeron 11 is provided with one away from an end of crossbeam 13 and inserts the spring tongue 112 in underframe 2 limes superiors holes and smallest limit hole.In order to prevent jointed shaft 11 play and coming off on longeron 11, each jointed shaft 11 also is provided with a spring cotter 110 at the end away from anti-rotation block 113.
As shown in Figure 1, when bumper/spoiler 1 is in the normal vehicle operation state, make bumper/spoiler 1 be in lockup state in the smallest limit hole of spring tongue 112 insertion vehicle frames 2, at this moment, the departure angle of vehicle is (that is: when vehicle is placed on the ground 4, the angle that the line of rear bumper 1 nadir and rear wheel 3 nadirs and ground 4 form) be the α angle, to play the buffering accidental impact and to prevent that people and animals from piercing the effect of vehicle bottom.As shown in Figure 3, when vehicle before by special road conditions, extract spring tongue 112 after can stopping, bumper/spoiler 1 is upwards turned to a limes superiors position of setting, spring tongue 112 is aimed in the insertion underframe 2 limes superiors holes, this moment, the departure angle of vehicle was the r angle, obviously the r angle is greater than the α angle, so, vehicle can pass through non-standard highway, open-air, the ferry bigger than the railway of elevated formation level or diff-H etc. needs the road conditions of big departure angle, treat by after these special road conditions, spring tongue 112 is extracted in parking, bumper/spoiler 1 is pivotally lowered into the smallest limit position again from the limes superiors position, again spring tongue 112 is inserted the smallest limit hole and makes bumper/spoiler be in lockup state, and vehicle has returned to the cruising state again like this.
Consider that rear bumper 1 needs artificial upset when changing the departure angle state, in order to reach the labour-saving purpose, the utility model respectively is provided with the assisting device of its upset of help on two longerons 11 of rear bumper 1.Consider the purpose that does not affect the appearance and protect assisting device, assisting device preferably is arranged on the inboard of longeron 11 in the present embodiment.Consult Fig. 4, Fig. 5, this assisting device comprises: the anti-rotation block 113 in order to stop jointed shaft 11 to rotate relative to vehicle frame 2 that is arranged on vehicle frame 2 corresponding jointed shaft 11 1 ends, be set in three axle sleeves 114 on the jointed shaft 11,115,116, gas spring 117, upper bracket 118 that links to each other with gas spring 117 upper ends and the lower bracket 119 that links to each other with gas spring 117 lower ends, be set in two axle sleeves 114 of jointed shaft 111 both sides, 116 captive joint with longeron 11 and are rotatably connected with jointed shaft 111, are set in axle sleeves 115 in the middle of the jointed shaft 111 and fix with jointed shaft 111 chuckings and captive joint with upper bracket 118.Upper bracket 118 is captiveed joint with the axle sleeve 115 at jointed shaft 11 middle parts by screw, and axle sleeve 115 is that chucking is fixing with jointed shaft 11, and jointed shaft 11 is that relative underframe 2 is fixed, so upper bracket 118 does not rotate relative to underframe 2.When the longeron 11 of rear bumper was pivotally lowered into the smallest limit position together with axle sleeve 114,115 with respect to underframe 2, gas spring 117 was compressed and has anti-elastic force, thus labour-saving purpose when reaching rear bumper 1 and upwards lifting.When rear bumper upwards turned to the limes superiors position together with axle sleeve 114,115 with respect to underframe 2, gas spring 117 was stretched and has anti-elastic force, thus labour-saving purpose when reaching rear bumper 1 upset downwards.
In order to strengthen the intensity of upper bracket 118, in the present embodiment, upper bracket 118 comprises two orthogonal triangular plates 1181,1182, and wherein triangular plate 1181 vertically is connected on the outer peripheral face of axle sleeve 115, and set square 1182 laterally is connected on the outer peripheral face of axle sleeve 115.
In other embodiments, the also replacements such as coil spring, rubber spring or high resiliency chemical fiber spring of available equal effect of gas spring 117.Obviously, also replacement such as the pneumatic latch of available equal effect or gas-liquid latch of spring tongue 111.
In addition, above-mentioned turnable bumper can be applied on the side rail of vehicle equally, prevent when making side rail can be implemented in normal vehicle operation that function that people and animals pierce from can stop maintenance or upwards dig side rail, easy access and operation when changing spare tyre again.Concrete structure as for side rail belongs to prior art, repeats no more herein.
The above only is a preferable possible embodiments of the present utility model, and unrestricted protection domain of the present utility model, and the equivalent structure that all utilization the utility model specification sheetss and accompanying drawing content have been done changes, and all is included in the protection domain of the present utility model.
