Abstract
The utility model discloses a front collision buffering and protecting device for cars. A bumper is fixed on a drive shaft which is installed on a main oil cylinder. A driven shaft is arranged in an auxiliary oil cylinder. The front end of the driven shaft is fixed with an auxiliary bumper. A first operating spring, a second operating spring and a main piston are also arranged in the main oil cylinder. A return spring is installed in the auxiliary oil cylinder and is sheathed on the driven shaft. A driven operating spring and an auxiliary piston are also arranged in the auxiliary oil cylinder; the driven operating spring is positioned between the driven shaft and the auxiliary piston. Hydraulic oil is filled in a communicated oil cavity between the main piston and the auxiliary piston. The utility model can effectively relieve impact force generated when collisions occur and better protect cars from being damaged by collision.
Description
The utility model relates to a kind of buffer protection device that prevents auto against, belongs to vehicle anticollision device field.
At present; prevent the device of auto against in the prior art; just simply that a bulk strength is higher bumper clamp is on the crossbeam of automotive front end; though this mono-bumper system is simple in structure; but when automobile bumps; it can only collide with the collision thing with confronting the tough with toughnees, can not cushion or lower impulsive force effectively, so it prevents that the protection effect of colliding is poor.
The purpose of this utility model is: provide a kind of frontal crash of vehicles buffer protection device with certain pooling feature, to overcome above-mentioned the deficiencies in the prior art.
The utility model is to constitute like this: it comprises bumper/spoiler (1), bumper/spoiler (1) is fixed on the imput shaft (2), imput shaft (2) is contained on the master cylinder (3), master cylinder (3) is parallel to each other with the axis of auxiliary oil cylinder (4) and its oil pocket communicates, driven axle (5) is housed in auxiliary oil cylinder (4), front end at driven axle (5) is fixed with secondary bumper/spoiler (13), first working spring (6) also is housed in master cylinder (3), second working spring (7) and main piston (8), main piston (8) places between first working spring (6) and second working spring (7), the bottom of imput shaft (2) contacts with first working spring (6), pull back spring (9) is contained in the auxiliary oil cylinder (4) and is enclosed within on the driven axle (5), passive working spring (10) and auxiliary piston (11) also are housed in auxiliary oil cylinder (4), passive working spring (10) places between driven axle (5) and the auxiliary piston (11), is filled with hydraulic oil (12) in main piston (8) and pair are drawn together the oil pocket that communicates between the plug (11).
Owing to adopted technique scheme, the utility model compared with prior art has the advantage of the impulsive force that is produced can damp impacts the time, therefore can protect automobile suffered injury when collision preferably.During use, major-minor oil cylinder of the present utility model can be fixed on together the chassis front end of automobile, bumper/spoiler (1) is stretched out about the about 25cm of headstock, when automobile suffers head-on crash, bumper/spoiler (1) at first contacts by the collision thing, impulsive force during its collision passes to first working spring (6) respectively by imput shaft (2), main piston (8) and second working spring (7), so just carried out level 2 buffering, main piston (8) passes to auxiliary piston (11) by hydraulic oil (12) with impulsive force and driven axle (5) is stretched out after secondary bumper/spoiler (13) touches by the collision thing simultaneously, passive working spring (10) is compressed, thereby carries out third stage buffering.Therefore, the utility model can cushion and the impulsive force when reducing auto against widely, thereby protects automobile effectively.After collision disappeared, pull back spring (9) made each parts automatically restore to original state again.
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment of the present utility model: bumper/spoiler (1) and secondary bumper/spoiler (13) all can adopt bumper material of the prior art to make, bumper/spoiler (1) is fixed on the imput shaft (2), imput shaft (2) is contained on the master cylinder (3), master cylinder (3) and auxiliary oil cylinder (4) preferably are made as one, when making, its axis is parallel to each other and its oil pocket is communicated mutually, in auxiliary oil cylinder (4), load onto driven axle (5), at the fixing secondary bumper/spoiler (13) of of the front end of driven axle (5), in master cylinder (3), load onto first working spring (6), second working spring (7) and main piston (8), main piston (8) is placed between first working spring (6) and second working spring (7), and the bottom of imput shaft (2) is contacted with first working spring (6), be contained in pull back spring (9) in the auxiliary oil cylinder (4) and be enclosed within on the driven axle (5), in auxiliary oil cylinder (4), refill passive working spring (10) and auxiliary piston (11), passive working spring (10) is placed between driven axle (5) and the auxiliary piston (11), in the oil pocket that communicates between main piston (8) and the auxiliary piston (11), be full of hydraulic oil and (12).
Claims (1)
