Abstract
The utility model discloses a telescopic type automobile bumper. The telescopic type automobile bumper comprises a left bumper body, a right bumper body, a bracket, a supporting bar, a left telescopic hydraulic cylinder, a right telescopic hydraulic cylinder, a rail trough, a crashproof hydraulic cylinder, a spring, and a fixing rack. The telescopic type automobile bumper is characterized in that both the left telescopic hydraulic cylinder and the right telescopic hydraulic cylinder are controlled by an electric oil pump and a control valve. When the oil pump is positively rotated, the left telescopic hydraulic cylinder retracts at first and pushes out the left bumper body to the target position. Because an oil path of the valve linked to the left telescopic hydraulic cylinder is changed, the right telescopic hydraulic cylinder retracts and pushes out the right bumper body to the target position. Then a travel switch on the right telescopic hydraulic cylinder is switched off, and a motor of the oil pump positively rotates to control a circuit. When an automobile runs, the left bumper body, the right bumper body and the bracket form an approximate equilateral triangle. Once problems occur, the triangle structure can remove a barrier from the knocked position or stagger the car position from the barrier. At the same time, the triangle structure can absorb the energy generated in the knock so that collapsing force and damage caused by the accident can be decreased. The left bumper body and the right bumper body retract to the resetting positions at the time of parking.
Description
Technical field
The utility model relates to a kind of device that guarantees running safety, a kind of specifically retractable vehicle bumper/spoiler.
Background technology
At present Federal bumper all is fixed, and itself lacks flexibility bumper/spoiler, if when automobile runs into collision case, can cause very big loss.
Summary of the invention
The purpose of this utility model provides a kind ofly to be had elasticity, can alleviate the damnous retractable vehicle bumper/spoiler of collision case.
The technical solution of the utility model is achieved in that it is by left thick stick body, right thick stick body, support, strut bar, left side telescopic hydraulic cylinder, right telescopic hydraulic cylinder, the rail groove, crashproof hydraulic actuating cylinder, spring, fixed mount is formed, be characterized in left thick stick body bending two ends, the one end bending of right thick stick body, the two is connected as hinge with support, a strut bar is respectively arranged for flexibly connecting at left thick stick body and right thick stick body middle part, the other end of two strut bars is connected with right telescopic hydraulic cylinder piston with left telescopic hydraulic cylinder respectively, left side telescopic hydraulic cylinder is connected as hinge with the two ends of support respectively with right telescopic hydraulic cylinder one end, on mid-stent, there are a rail groove and support to be bolted to connection, 2-5 crashproof hydraulic actuating cylinder and 4-16 spring are arranged between support and the fixed mount, and be bolted to connection and be one.
Fixed mount is fixed by bolts to the place ahead and the rear of automobile.Switch on when work.Left side telescopic hydraulic cylinder and right telescopic hydraulic cylinder are controlled by electric oil pump and by-pass valve control, when oil pump just changes, the retraction of left side telescopic hydraulic cylinder elder generation, left thick stick body is released, the back put in place owing to the valve with its interlock has changed oil circuit, and right thick stick body is released in the retraction again of right telescopic hydraulic cylinder, after right thick stick body put in place, the travel switch that is loaded on the right telescopic hydraulic cylinder place of putting in place disconnects oil pump motor was just being changeed control circuit.Left side thick stick body and right thick stick body and support form an approximate equilateral triangle during work.
When oil pump reversed, right telescopic hydraulic cylinder stretched out earlier, after right telescopic hydraulic cylinder puts in place, by pull bar by-pass valve control is turned back with its interlock, pressure oil enters left telescopic hydraulic cylinder, and after left telescopic hydraulic cylinder put in place, the travel switch of its interlock disconnected the oil pump reverse turn control circuit.Left side thick stick body and the retraction of right thick stick body reset.
The beneficial effects of the utility model are: when galloping, but its device of chaufeur direct control, because left thick stick body, right thick stick body and support are triangular in shape, crashproof hydraulic actuating cylinder and spring are arranged between support and the fixed mount, the one, obstacle can be pushed aside and be hit the position, or with the position of this car obstacle that staggers; The 2nd, can absorb the energy of collision, thereby reduce the loss that destructive force and accident cause.Operation is simple and feasible for its device, social benefit and remarkable in economical benefits.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a work scheme drawing of the present utility model.
Among the figure 1, left thick stick body, 2, right thick stick body, 3, support, 4, strut bar, 5, left telescopic hydraulic cylinder, 6, right telescopic hydraulic cylinder, 7, the rail groove, 8, crashproof hydraulic actuating cylinder, 9, spring, 10, fixed mount.
The specific embodiment
Shown in the figure, a kind of retractable vehicle bumper/spoiler of the utility model mainly adopts steel plate or light metal to process.At first 5 crashproof hydraulic actuating cylinders 8 and 8 spring 9 one ends and fixed mount 10 are used bolt, then, again that the other end and the support 3 of crashproof hydraulic actuating cylinder 8 pistons, one end and spring 9 is fixing; Left thick stick body 1, left telescopic hydraulic cylinder 5 and right thick stick body 2, right telescopic hydraulic cylinder 6 are installed respectively at the two ends of support 3 to be connected as hinge, a left side thick stick body 1 and right thick stick body 2 middle parts flexibly connect with a strut bar 4 respectively, and the other end of two strut bars 4 and left telescopic hydraulic cylinder 5 and right telescopic hydraulic cylinder 6 are connected as hinge.A rail groove 7 is installed above in the middle of support 3, and fixing by bolt and support 3, left telescopic hydraulic cylinder 5 and right telescopic hydraulic cylinder 6 move in rail groove 7.Fixed mount 10 is fixed by bolts to the place ahead and the rear of automobile.
Switch on when work.Left side telescopic hydraulic cylinder 5 and right telescopic hydraulic cylinder 6 are controlled by electric oil pump and by-pass valve control, when oil pump just changes, left side telescopic hydraulic cylinder 5 first retractions, left thick stick body 1 is released, valve with its interlock after putting in place has changed oil circuit, and the retraction again of right telescopic hydraulic cylinder 6 is released right thick stick body 2 again, after right thick stick body 2 put in place, the travel switch that is loaded on right telescopic hydraulic cylinder 6 places of putting in place disconnects oil pump motor was just being changeed control circuit.Left side thick stick body 1 and right thick stick body 2 form an approximate equilateral triangle with support 3 when work.
When oil pump reversed, right telescopic hydraulic cylinder 6 stretched out earlier, after right telescopic hydraulic cylinder 6 puts in place, by pull bar by-pass valve control is turned back with its interlock, pressure oil enters left telescopic hydraulic cylinder 5, and after left telescopic hydraulic cylinder 5 put in place, the travel switch of its interlock disconnected the oil pump reverse turn control circuit.Left side thick stick body 1 and right thick stick body 2 retractions reset.
The purpose that the utility model is designed to movable and foldable is the size of car load when reducing parking or low speed driving, blocks up to save parking place or minimizing, can reduce the loss of collision during high speed again.
