Abstract
The utility model belongs to an automobile bumper, and particularly relates to a cushioning bumper which comprises a bumper body and a base plate, wherein the bumper body is provided with a cushioning device. When an automobile is collided, the cushioning device can disperse and bear collision force, increase of deformation of an automobile body due to too concentrated collision force, and personal safety of passengers and a driver in the automobile is not endangered. Besides, the cushioning device comprises a hydraulic cushioning device and a spring cushioning device, so that the automobile bumper can be produced to achieve diversity according to actual requirements. In addition, the outer surface of the cushioning device is wrapped with a soft cushioning layer, so that the uppermost cushioning device is protected, and part of cushioning force is shared by the cushioning device.
Description
Technical field
The utility model belongs to a kind of Federal bumper, is specifically related to a kind of energy management bumper.
Background technology
Bumper/spoiler is one of important exterior trimming parts of automobile, as one independently assembly be installed in automotive front, not only have intensity, rigidity, see from safety, can play buffer action when automobile crashes, the protection before and after car body; And from seeing in appearance, can be very natural be combined in one with car body, completely be integral, have excellent decoration property, become the vitals of decorating the automobile external form.
The front and rear that is fixed on car body of the present direct rigidity of Federal bumper has no buffering between bumper/spoiler and the car body.When automobile bumps, though bumper/spoiler can produce the certain protection effect to car body since between bumper/spoiler and the car body for being rigidly connected, the power that collision produces has and acts on greatly on car stops, and car body is produced broken the ring, and the driver and conductor is produced danger.
The utility model content
The utility model provide a kind of simple in structure, cost is low, the tangible energy management bumper of buffering effect, this utility model also has the advantage of secondary buffer.
In order to solve the problems of the technologies described above; The utility model provides following technical scheme: energy management bumper comprises bumper body, substrate; Described bumper body is provided with shock absorber; Shock absorber is hydraulic damping device or spring bumper, and shock absorber is located at the middle part and the both ends of bumper body, and the outside face of shock absorber coats soft cushion layer.
Adopt technique scheme; In the utility model, simple in structure, cost is low, the middle part of bumper body and two ends all are provided with shock absorber; When automobile when bumping; Shock absorber can disperse impact force to bear, and crash-avoidance power too concentrates the distortion that makes vehicle body to strengthen, and jeopardizes interior passenger of car and driver's life safety; Shock absorber is hydraulic damping device and spring bumper simultaneously, and we can produce through the conditions of demand of reality like this, reach product diversity; The outside face of shock absorber coats soft cushion layer in addition, has so not only protected topmost shock absorber, and has shared a part of cushion effect for shock absorber.
Further, an end of described spring bumper connects bumper body, and the other end connects substrate; Avoid spring bumper directly to contact with vehicle body; Destroy body structure, the protection that connects in collision time the contour structures of vehicle body, be convenient to substrate and vehicle body is better fitted.
Further, an end of described hydraulic damping device connects bumper body, and the other end connects substrate; Avoid hydraulic damping device directly to contact with vehicle body; Destroy body structure, the protection that connects in collision time the contour structures of vehicle body, be convenient to substrate and vehicle body is better fitted.
Further, described substrate edge is provided with draw-in groove, is provided with corresponding airbag in the draw-in groove; When the shock absorber pressed towards substrate; Force airbag distortion simultaneously, further played the effect (being equivalent to secondary buffer) of buffering, better protection the contour structures of vehicle body.
Further, consider effect and the durability and the cost of distortion, airbag adopts the inflatable structure of rubber, and the draw-in groove that matches with airbag also adopts elastomeric material.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the structural representation of the utility model embodiment 1 energy management bumper;
Fig. 2 is the structural representation of the utility model embodiment 2 energy management bumpers;
Fig. 3 is the structural representation of draw-in groove and airbag in the utility model.
The specific embodiment
As shown in Figure 1: energy management bumper comprises bumper body 1, substrate 2; Described bumper body 1 is provided with spring bumper 3, and an end of spring bumper 3 connects bumper body 1, and the other end connects substrate 2; Spring bumper 3 is located at the middle part and the both ends of bumper body 1; The outside face of spring bumper 3 coats soft cushion layer 6, and as shown in Figure 3: described substrate 2 edges are provided with draw-in groove 4, are provided with corresponding airbag 5 in the draw-in groove 4; Airbag 5 is the inflatable structure of rubber, and the draw-in groove 4 that matches with airbag 5 also is elastomeric material.
When automobile bumps; The effect of buffering is played in spring bumper 3 compressions on the bumper body 1; Protected the contour structures of automobile; The outside face of spring bumper 3 coats soft cushion layer 6 in addition, has so not only protected topmost shock absorber, and has shared a part of cushion effect for spring; Simultaneously during bumper body 1 pressed towards substrate 2, the draw-in groove 4 and airbag 5 structures of the rubber on the substrate 2 can cushion again, have further protected the car conour structure.
As shown in Figure 2: energy management bumper comprises bumper body 1, substrate 2; Described bumper body 1 is provided with hydraulic damping device 7, and an end of hydraulic damping device 7 connects bumper body 1, and the other end connects substrate 2; Hydraulic damping device 7 is located at the middle part and the both ends of bumper body 1; The outside face of hydraulic damping device 7 coats soft cushion layer 6, and as shown in Figure 3: described substrate 2 edges are provided with draw-in groove 4, are provided with corresponding airbag 5 in the draw-in groove 4; Airbag 5 is the inflatable structure of rubber, and the draw-in groove 4 that matches with airbag 5 also is elastomeric material.
When automobile bumps; The effect of buffering is played in hydraulic damping device 7 compressions on the bumper body 1; Protected the contour structures of automobile; The outside face of hydraulic damping device 7 coats soft cushion layer 6 in addition, has so not only protected topmost shock absorber, and has shared a part of cushion effect for spring; Simultaneously during bumper body 1 pressed towards substrate 2, the draw-in groove 4 and airbag 5 structures of the rubber on the substrate 2 can cushion again, have further protected the car conour structure.
Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection domain of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
