The combined type automobile mechanical impact buffering device is structurally characterized in that symmetrical transmitting devices are mounted at the front end and the rear end of the bottom of an automobile body, each transmitting device consists of a metal plate, a first spring, a transmitting shaft and a first track, the metal plate and one end of the transmitting shaft are perpendicularly fixed together via the first spring, the other end of the transmitting shaft extends to the outside of the first track and is connected with the front end of a piston rod, the rear end of the piston rod penetrates through a second track to be placed in the front of a cylinder, a piston fixed at the rear end of the piston rod is fixed in the cylinder, a second spring is sleeved on the piston rod at the front end of the second track, a third spring is arranged in the bottom of the cylinder, and a safety valve is disposed outside the bottom of the cylinder. The combined type automobile mechanical impact buffering device is simple in structure, is novel and unique, has better buffering property and fine service effect, effectively prevents damages to automobile bodies and injury to human bodies, and has high economic benefit and social benefit.

Description

Composite automobile mechanical impact shock absorber

One, technical field

The utility model relates to a kind of composite automobile mechanical impact shock absorber.

Two, background technology

The development history of world car technology, changing an angle also is a traffic accident history, the traffic accident that the annual whole world takes place is ten hundreds of, has brought very grave disaster and misfortune for numerous families.From the automobile invention so far, the driving engine of automobile, car body is anticorrosion and traveling comfort has all had revolutionary variation more at first, on the automotive safety fail-safe structure, also rest on only and add the level that dress safety strap in bumper/spoiler, the car adds air bag before and after the car body, because the problem of structural existence, result of use is poor, can not effectively prevent injury, and the development of society makes that the mankind are more and more stronger to the dependence of automobile to car body and human body.Therefore, how to develop and have better resiliency, alleviate car body damage that collision causes and, be the problem that urgently will solve the automobile buffering device of the injury of human body, thus improve imperative.

Three, utility model content

At above-mentioned situation, for solving the defective of prior art, the purpose of this utility model is to provide a kind of composite automobile mechanical impact shock absorber, and it is poor effectively to solve existing automobile protective device result of use, can not effectively prevent the problem to the injury of car body and human body.

The technical scheme that the utility model solves is, before the car body bottom, the transfer device of symmetry is equipped with at back two ends, transfer device is by metal sheet, first spring, the transmitter shaft and first track constitute, metal sheet is vertical configuration through an end of first spring and transmitter shaft and is fixed together, the other end of transmitter shaft stretches out the outside of first track, and be connected with the front end of piston rod, the rear end of piston rod is passed second track and is placed in the cylinder front portion, the piston that is fixed on the piston rod rear end is arranged in the cylinder, the upper cover of piston rod of the second track front end is equipped with second spring, the 3rd spring is arranged in the cylinder bottom, there are safety valve, second spring in the cylinder bottom outside, second track, piston rod, piston, cylinder, the 3rd spring and safety valve constitute shock absorber.

The utility model is simple in structure, and is novel unique, and better cushion characteristic can be provided, and result of use is good, effectively prevents the injury to car body and human body, has great economic and social benefit.

Four, description of drawings

Fig. 1 is a structural front view of the present utility model.

Fig. 2 is an air cylinder structure front view of the present utility model.

Fig. 3 is a pulley block structure front view of the present utility model.

Five, the specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.

As Fig. 1-shown in Figure 2, structure of the present utility model is, before car body 13 bottoms, the transfer device of symmetry is equipped with at back two ends, transfer device is by metal sheet, first spring, the transmitter shaft and first track constitute, metal sheet 1 is vertical configuration through an end of first spring 5 and transmitter shaft 6 and is fixed together, the other end of transmitter shaft 6 stretches out the outside of first track 2, and be connected with the front end of piston rod 9, the rear end of piston rod is passed second track 8 and is placed in cylinder 3 front portions, the piston 10 that is fixed on the piston rod rear end is arranged in the cylinder, the upper cover of piston rod of the second track front end is equipped with second spring 7, the 3rd spring 11 is arranged in the cylinder bottom, there are safety valve 12, the second springs the cylinder bottom outside, second track, piston rod, piston, cylinder, the 3rd spring and safety valve constitute shock absorber.

In order to guarantee result of use, said transmitter shaft 6 is connected with piston rod through brake cable 4 or assembly pulley; Said assembly pulley (as shown in Figure 3) is made up of two pulleys 14 and wirerope 15, and two pulleys are connected with wirerope, and the two ends of wirerope are connected with transmitter shaft, piston rod respectively.

The utility model is that a kind of dependence piston compresses confining gas successively and spring makes its order deformation, absorbs the Impact energy that is transported by transfer device and then reduces mechanical impact to the protective device of vehicle and personnel's damage, is characterized in:

1, can provide secondary buffer:

When impulsive force is delivered to piston rod, promote its compressed gas gas in the jar to the withstand voltage limit of safety valve, safety valve is opened pressure release, and this is to cushion for the first time; If for the first time buffering fails to absorb fully the external impact energy, car body continued under external force distortion and caved in this moment, and deformation is conducted and continued advance compression the 3rd spring and gas in the jar of pushing piston to transfer device secondary buffer is provided. Piston compression stroke was corresponding when the free state length of the 3rd spring should be with the safety valve pressure release.

2, the installation site is flexible:

Transfer device of the present utility model generally is installed in the front and back bumper/spoiler left and right sides of position inwards, also can be installed in the inboard, any car body position that easily collides when having an accident, only need reinforce, and reserve transmitter shaft moving track installation site and get final product the transfer device front end sheet metal.

When 3, the utility model and flexible bumper/spoiler or automobile shirt rim were used, effect was better:

When bumping, flexible bumper/spoiler plays a role earlier, being compressed to the limit still continues deformation fully during the buffering collision of closed energy and promotes the Piston Compression cylinder, and then safety valve is opened pressure release, and then compress the 3rd spring, and being equivalent in collision process, have No. three buffer meetings, each parts is arranged in pairs or groups under the rational prerequisite, the buffering collision of closed energy effectively prevents the injury to car body and human body fully.

The utility model is simple in structure, and is novel unique, and secondary buffer can be provided, has better cushion characteristic, can alleviate car body damage that collision causes to greatest extent and, reduce collision back automotive servicing input, have great economic and social benefit the injury of human body.
