Abstract
The utility model discloses an automotive anti-collision shock damping device, which is composed of a bumper arranged on an automobile chassis, etc. A rubber shock damping gas bag is arranged on an automobile head bumper (1) and an automobile end bumper (9), and the bumper (1) is connected with the girder (11) of the automobile chassis by a pair of hydraulic dampers and a movable push bar which are arranged symmetrically; the piston part (3a) of the hydraulic damper is fixedly connected with the bumper (1), and the hydraulic cylinder part (3b) is connected with the front end of the girder; the front end of the movable push bar is fixedly connected with the bumper and can relatively slip on each bridging beam; the bar body passes through each bridging beam of the girder horizontally, and the contact part of the push bar and the bridging beam is provided with a damping spring. The utility model improves the automotive anti-collision performance.
Description
The utility model belongs to automobile, and especially the automobile collision preventing safety device is made the field.
At present; both at home and abroad the mode on metal bumper and metal protection hurdle is all adopted in the protection when the bump basically to auto body; when car collision, play a protective role; but metallo-contacts firmly during owing to bump; make tool moment generation huge impact power; automobile suffers very big loss in bump as a result, drives that the personnel of adopting also more injures and deaths.
The purpose of this utility model is to be the crashproof safety structure of a kind of more failure-free of automobile design, make it prolong the effect of impact time as much as possible, impact is cut down step by step, and to reduce to clash into the impulsive force that is produced, actv. alleviates vehicle loss and driver and crew's injures and deaths.
The purpose of this utility model is to reach by following design.
Hitting on the shock-damping structure by being arranged on the automobile collision preventing that bumper/spoiler on the car chassis etc. forms, on headstock bumper/spoiler and tailstock bumper/spoiler, be provided with the rubber shock-absorbing air bag, bumper/spoiler is connected with the car chassis crossbeam with movable push bar by a pair of symmetrically arranged liquid damper, the piston portion and the bumper/spoiler of liquid damper are connected, and the hydraulic actuating cylinder part links to each other with the crossbeam front end; The front end and the bumper/spoiler of movable push bar are connected, and can do relative slippage on each crossbeam, and body of rod on even keel passes each crossbeam of crossbeam, is provided with damping spring with the crossbeam contact part on the push rod.
After having adopted structure as above, when automobile impacting, the air bag of bumper/spoiler stands in the breach and is compressed, the front bumper opposite sense that automobile advances below impact effect motion simultaneously, promote the motion of liquid damper the axis of the piston, the liquid in the liquid damper is compressed.The motion of bumper/spoiler promotes the bump push rod and moves to the tailstock, is connected the spring on the push rod, just impact has been distributed on a plurality of positions of crossbeam, makes impact obtain buffering and dispersion.Huge impact when three grades of damping devices have been cut down bump step by step can alleviate vehicle loss and driver and crew's injures and deaths effectively.
Description of drawings is as follows:
Fig. 1 adopts car chassis structure birds-eye view of the present utility model.
Can see in Fig. 1, on headstock bumper/spoiler and the tailstock bumper/spoiler 9 rubber shock-absorbing air bag 2 and 10 are set, this air bag can be made the many air chamber structures of hollow with heavily loaded rubber manufacturing.Bumper/spoiler 1 dyes 11 by a pair of symmetrically arranged liquid damper greatly with push rod 4 and car chassis and is connected, the piston portion 3a and the bumper/spoiler of liquid damper are connected, hydraulic actuating cylinder part 3b links to each other with the crossbeam front end, the front end and the bumper/spoiler of movable push bar are connected, body of rod on even keel passes each crossbeam of crossbeam, and can do relative slippage mutually at each crossbeam, and being provided with damping spring (shown among the figure 5,6,7) with the crossbeam contact part on the push rod, tailstock crossbeam portion is provided with rubber pad 8.
Claims (1)
