Description
Technical field
The utility model relates to crusherbull zone fender guard field, is specially the multistage collision bumper of a kind of automobile for reducing auto against impulsive force.
Background technology
In technical field of vehicle safety, when colliding for avoiding automobile there is larger damage in headstock and frame section, and all kinds of automobile is all provided with bumper/spoiler or similar bumper system in front portion.This kind of bumper/spoiler provides certain buffering and protection when impact force is less by the plastic deformation of bump rubber and associated components; But be usually that height is rigidly connected with car chassis or Vehicle Frame Design due to bumper part, when making collision generation, impulsive force still acts on automobile, when impulsive force is larger, still can threaten navigating mate safety.
For these reasons; some vehicles are also provided with supporting energy disperser to protect; in the collision process of automobile; because collision velocity when collision occurs is larger; require that energy disperser has larger deflection to carry out damp impacts momentum; and common hydraulic draft gear when collision velocity is larger, often rigidity is comparatively large, impact comparatively large, implement the effect that cannot reach anticipation.
Utility model content
The technical matters that the utility model solves is to provide a kind of automobile multistage collision bumper, for connecting Federal bumper and chassis, reduces impulsive force during auto against, and then solves the shortcoming in above-mentioned background technology.
The technical matters that the utility model solves realizes by the following technical solutions:
The multistage collision bumper of a kind of automobile, the piston comprising cushion cylinder and can move in cushion cylinder, a shoe cream room is left between described cushion cylinder and piston, hydraulic oil is filled in this shoe cream room, and be connected with petrol storage tank by one-way throttle valve on side, side, simultaneously, outside cushion cylinder, by piston rod side, be also provided with one be sleeved on cushion cylinder surface and the first-level buffer seat that can carry out axial slip along cushion cylinder, be connected with bottom piston rod by a Compress Spring bottom this first-level buffer seat; A mount pad is then respectively arranged with for connecting car chassis and insurance bar body in the outside of described first-level buffer seat and cushion cylinder.
In the utility model, the inner side of described first-level buffer seat is provided with spline, and the outside face of described cushion cylinder is provided with corresponding spline, when first-level buffer seat plays buffer action, whole cushion cylinder and its relative motion are realized by spline slide, in order to prevent from reversing.
In the utility model, the piston in described shoe cream room and be also provided with a Compress Spring between cushion cylinder as pull back spring, carries out buffering in order to auxiliary shoe cream room and lets out power.
In the utility model, between described piston and cushion cylinder and between cushion cylinder and piston rod, be provided with sliding seal.
Beneficial effect: the utility model structure is simple, reliable operation, the effect of effectively buffering can be played while connecting bumper/spoiler and chassis, simultaneously, the constructional feature special due to it and have two-stage buffering, the needs of various collision can be met, when collide less time, buffering is produced by first-level buffer, when collision strengthens, acted on by level 2 buffering generation, ensure that safety during auto against to greatest extent; Simultaneously; because the first-level buffer device seat in its two-stage buffer structure is movable type buffering device seat; the piston rod of movement and oil cylinder can be isolated from the outside open, good protective effect is served to cushion cylinder, effectively can meet the job requirement of automobile under severe rural atmosphere.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
Wherein: 1, car chassis Connection Block; 2, pull back spring; 3, shoe cream room; 4, piston; 5, piston rod packing; 6, piston rod; 7, recoil spring; 8, first-level buffer seat; 9, bumper/spoiler Connection Block; 10, cushion cylinder; 11, one-way throttle valve; 12, spline; 13, petrol storage tank.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See the preferred embodiment of the multistage collision bumper of a kind of automobile of Fig. 1, in the present embodiment, comprise piston 4, cushion cylinder 10 and first-level buffer seat 8, piston 4 and cushion cylinder 10 and all Relative sliding can be realized between cushion cylinder 10 and first-level buffer seat 8; The outside of cushion cylinder 10 and first-level buffer seat 8 is respectively arranged with car chassis Connection Block 1 and bumper/spoiler Connection Block 9 is respectively used to connect car chassis and Federal bumper.
Shoe cream room 3 between cushion cylinder 10 and piston 4, as epitrochoidal chamber, is filled with hydraulic oil in it, and the other perforate in its side, and connect petrol storage tank 13 at tapping by one-way throttle valve 11.And a pull back spring 2 is also installed between cushion cylinder 10 and piston 4 as auxiliary pressure relief element; And piston rod 6 is connected with at piston 4 rear portion, piston rod 6 realizes sealing by piston rod packing 5 and cushion cylinder 10, and between piston rod 6 and first-level buffer seat 8, be provided with a recoil spring 7.
In the present embodiment, recoil spring 7 and pull back spring 2 are Compress Spring, and are provided with sliding seal between piston 4 and cushion cylinder 10 and between piston rod packing 5 and piston rod 6 to realize piston 4, sealing between piston rod 6 and cushion cylinder 10.
When the present embodiment uses, car chassis Connection Block 1 is connected with car chassis and bumper/spoiler respectively with bumper/spoiler Connection Block 9, hydraulic oil is full of in shoe cream room 3, when Federal bumper is collided, impact and be delivered to energy disperser by car chassis Connection Block 1 and bumper/spoiler Connection Block 9, start impact moment speed larger, recoil spring 7 is subject to impact compress, absorb striking momentum, the formation first order cushions, along with the increasing of collision impact and recoil spring 7 displacement, first-level buffer seat 8 and recoil spring 7 can promote piston rod 6 and move, and then drive piston 4 to compress shoe cream room 3, the oil pressure of shoe cream room 3 is increased, hydraulic oil enters petrol storage tank 13 by one-way throttle valve 11, and when the pressure oil of shoe cream room 3 li is by forming damping during one-way throttle valve 11, reach buffering object, the formation second stage is cushioned, second stage buffer capacity bears higher impact force, and in compression process, because the outer wall of cushion cylinder 10 and the inwall of first-level buffer seat 8 are respectively arranged with the spline 12 and spline cooperatively interacted, when cushion cylinder 10 is when playing buffer action, first-level buffer seat 8 slides along spline 12, can effectively prevent energy disperser to twist phenomenon.
More than show and describe groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
