Abstract
The utility model relates to a safety reverse thrust buffering anticollision device of a vehicle, which is an attachment for absorbing energy for vehicle collision. A hardness energy absorption mode with the expense of deformation of components of an engine barn is altered when the vehicle collision happens. The configuration of the device is similar to a vibration damping device of the vehicle, and the utility model is composed of a compression spring energy absorption segment part and a reverse thrust plunger buffering segment part. Under the action of getting impact force of a spring pressure plate, a spiral spring is compressed until the impact energy is absorbed by a spring contact plate. Simultaneously, a first plunger piston is pushed by a push rod of the plunger piston for compressing the air in a cavity of the first plunger piston. In the state of high pressure, diversion is conducted to the air in the cavity of the first plunger piston by a baffle and the air is filled in a plenum chamber. A reverse thrust plunger is pushed forwards by expanded air, and the spring contact plate is pushed for counter compressing the spiral spring. The reverse thrust is formed for counteracting the impact force and prolonging the buffer space. The harm of people in the vehicle and the vehicle property loss can be reduced or avoided by the utility model in a flexible energy absorption mode.
Description
Affiliated technical field: the utility model is applied to a kind of accessory device of automobile impacting energy-absorbing, especially a kind of buffering percussive force to greatest extent, be installed on automotive front and afterbody, can be when being used for automobile and bumping with the automobile accessory device of occupant's injury and the reduction of vehicle degree of injury.
Background technology: at present, we know when our vehicle in use crashes can cause the badly damaged of driver and crew's injures and deaths and vehicle because the action of inertia of vehicle can produce strong wallop.What we knew that present most of vehicle in use can effectively absorb collision energy when crashing is exactly engine bin and back freight house and front and back support longeron; be to rely on the shrinkage distortion in vehicle assembly and space to reach the effect that absorbs Impact energy alleviation impact; to realize protecting to greatest extent driver and crew's purpose of safety in the car; but this rigid contraction can not be finished with the softest effect all the time; and be cost to sacrifice vehicle assembly; final energy-absorbing effect is not obvious, also causes very big direct economic loss.
Summary of the invention: alleviate Impact energy in soft mode and reach the purpose that reduces personal casualty probability and direct economic loss in order effectively to overcome adverse consequences that rigid energy-absorbing causes, the utility model provides a kind of automobile accessory device, this device can turn over flexible way absorption Impact energy and before producing the certain reaction thrust inhibition impact continuity and the tailstock by actv., effectively reduction personnel injury and vehicle economic loss.
The technical scheme that its technical matters that solves the utility model adopts is: the design and installation of this device is at automobile head and afterbody, when automobile generation head-on crash or rear-end impact, compression spring energy-absorbing section and two sections designs of reaction thrust plunger breeze way by this device reach; Buffering, absorb, offset, impulsive force that produces during collision and inertia, when auto against, spring platen 1 revolves spring at the effect lower compression Luo of impulsive force and supports dish (notes: according to the difference of the dynamics of impact until spring, the length of spring compressed degree is also different) meanwhile the plunger push rod promote first plunger and compress air in first plunger cavity, diversed water conservancy diversion of air under suppressing state in first plunger cavity also charges into plenum chamber, the air push reaction thrust plunger that expands moves ahead, the reaction thrust plunger prolongs forward and promotes spring and supports the dish back-pressure Luo that contracts and revolve spring, formed a kind of reaction thrust offsetting impulsive force and to prolong cushion space thereby produce, the air in the reaction thrust plunger is advanced or shunk in the reaction thrust plunger cavity is discharged from from port or inspiration produces vapour lock and removes pressure preventing.
When buffering course finishes, Luo revolves the spring self-return and drives the first plunger return, and compressed air finishes compression in first plunger cavity, and the tension force return effect that the reaction thrust plunger revolves spring at Luo presses down gets back to the home position, and buffering course finishes.
The beneficial effects of the utility model are, during the collision happens accident, impact this device Luo revolve Luo in the spring energy-absorbing section revolve spring be compressed that buffering absorbs and reaction thrust plunger breeze way in the reaction thrust that produces offset the two unification, mutual action, thereby reach crashproof effect, its manufacture is simple, can repeated usage or maintenance use.
Description of drawings: the utility model is described further below in conjunction with accompanying drawing.Accompanying drawing is the utility model section-drawing, and component part is among the figure: spring platen (1), plunger push rod (2), Luo revolve spring (3), spring support dish (4), first plunger (5), first plunger cavity (6), plenum chamber (7), reaction thrust plunger (8), reaction thrust plunger cavity (9), port (10), reaction thrust plunger housing (11), baffle (12), etc. 12 parts form.
The specific embodiment: among the figure, spring platen (1) revolves spring (3) with Luo and is pressed in spring in advance above dish (4), is connected on first plunger (5) by plunger push rod (2), forms the flexible energy-absorbing buffering of spring space.First plunger (5) is in first plunger cavity (6), generally first plunger (5) is installed on the plunger push rod (2), since the predetermincd tension when first plunger (5) is installed by plunger push rod (2) pull down move spring platen (1) thus pushed down that Luo revolves spring (3) and spring supports dish (4) so that each assembly of cushion space does not become flexible and be maintained at the top of first plunger cavity (6), make and reserve maximum compression stroke space and maximum suction pressure in the plunger cavity of winning (6), reaction thrust plunger (8) revolves at Luo under the tension force of spring (3) and is pressed in reaction thrust plunger housing (11) bottom in advance in the ordinary course of things.
Among the figure, reaction thrust plunger (8) has formed first plunger cavity (6) so the center is a hollow form, generally reaction thrust plunger (8) is packed into by reaction thrust plunger housing (11) bottom, its reaction thrust plunger (8) becomes a kind of interactional two-way interaction mode of motion that seesaws with first plunger (5) type, there is a plenum chamber that is semicircle shape (7) that makes progress to promote reaction thrust plunger (8) and move ahead and form one reaction thrust buffering strength in reaction thrust plunger base design, to suppress the continuity of impact to induce air pressure upwards to produce thrust from the bottom.
Among the figure, go between the outer rim of reaction thrust plunger (8) and the reaction thrust plunger housing inner edge into a reaction thrust plunger cavity (9) be to play reaction thrust plunger (8) acting and the effect of compensating air when shrinking, a port (10) is arranged with inspiration and deaeration in the top of reaction thrust plunger housing (11), discharge air in the reaction thrust plunger cavity when moving ahead to prevent vapour lock at reaction thrust plunger (8), suck air is with pressure relief when the reaction thrust plunger retraction
Among the figure, it is that baffle (12) plays the effect that the guiding air pressure stream enters plenum chamber (7) in device that individual bossing is arranged in the bottom of reaction thrust plunger housing (11).
