Description

Automobile buffer collision protection device

technical field

The invention relates to an automobile anti-collision protection device, in particular to a buffer protection device for a frontal collision of an automobile.

Background technique

The anti-collision devices on the front of various automobiles on the market are all bumpers. When a frontal collision occurs, the bumper has no cushioning effect basically. In order to realize the buffering when the car has a frontal collision, the basic structure of an existing car collision buffer protection device is as follows: a group of active oil cylinders and a buffer are arranged at the front of the chassis of the car, and the piston of the active oil cylinder and the buffer The rod is connected with the bumper, the rear part of the seat located in the cab is hinged with the compartment floor, and a slave oil cylinder is arranged under the seat, the slave oil cylinder is connected with the active oil cylinder, and the piston rod of the slave oil cylinder is connected with the bottom of the seat . When the above-mentioned protection device collides with the front of the car, the active oil cylinder and the buffer can buffer the bumper, and at the same time, the seat is turned backward under the action of the driven oil cylinder, thereby playing a buffering and protective effect. However, the disadvantage is that when a collision occurs, the seat will be reclined immediately, which may cause a large impact on the neck of the person on the seat and cause damage; only relying on hydraulic pressure to buffer the bumper, the buffering process is not enough Fully, the vehicle will rebound, and the driver and passengers are vulnerable to secondary impact.

Contents of the invention

The object of the present invention is to provide an automobile buffering and collision protection device, which can realize multi-stage buffering and ideally reduce the impact degree of drivers and passengers when a collision occurs.

In order to achieve the above object, the present invention adopts the following scheme: the automobile buffer collision protection device has a bumper, a group of primary buffer oil cylinders arranged on the automobile chassis and seats arranged in the front row of the cab, and the bottom of each seat The rear end is hinged with the compartment floor, and a slave oil cylinder is arranged under each seat, the piston rod of the slave oil cylinder is hinged with the bottom of the seat, and the bumper is connected with the piston rod of each first-level buffer oil cylinder. It is characterized in that: There are two capsules between the bar and the first-level buffer oil cylinder. In a group of first-level buffer oil cylinders, the oil outlet of one first-level buffer oil cylinder is connected with an auxiliary brake device, and the oil outlets of the other first-level buffer oil cylinders are connected according to the average pressure. The way of distribution is respectively connected with the inner cavity of the two capsules. There are also secondary buffer oil cylinders corresponding to the number of driven oil cylinders on the chassis of the car. The front ends of the piston rods of each secondary buffer oil cylinders are connected with baffles, and the baffles are located in the safety At the rear of the bar, the oil outlets of each secondary buffer oil cylinder are connected with the oil inlets of each driven oil cylinder in one-to-one correspondence.

It can be seen from the above scheme that when the automobile equipped with the collision protection device provided by the present invention collides head-on and the bumper receives an impact, first, the first-level buffer oil cylinder buffers the bumper, and the auxiliary brake device performs auxiliary braking, and at the same time, the first-level buffer The liquid medium in the oil cylinder will be sprayed into the bladder, which is equivalent to installing an airbag on the vehicle; then, the secondary buffer cylinder will buffer the bumper again, and the secondary buffer cylinder will drive the driven cylinder to drive the seat and its upper The seat is reclined by a secondary buffer oil cylinder, the purpose is to recline after the impact is reduced, moderately slow down the violent degree of the recline, and avoid direct impact on the neck of the driver and passengers , It also increases the safety of the drivers and passengers.

The invention has reasonable structure and reliable performance. It adopts two buffers and reclines the seat, which can greatly reduce the collision degree of the driver and passengers, so that the vehicle and the drivers and passengers can be protected to the greatest extent.

Detailed ways

The present invention is further described below in conjunction with embodiment and accompanying drawing.

See Figure 1, Figure 2

The automobile buffer collision protection device provided by the present invention has a bumper 3, a group of primary buffer oil cylinders 13 arranged on the automobile chassis 1 and seats 9 arranged in the front row in the cab, and the rear end of each seat 9 bottom Hinged with the compartment floor 10, a slave oil cylinder 8 is arranged below each seat 9, and the piston rod 8a of the slave oil cylinder 8 is hinged with the bottom of the seat 9. The bumper 3 is connected with the piston rod 13a of each first-level buffer cylinder 13, and two bladders 2 are arranged between the bumper 3 and the first-level buffer cylinder 13. There is one first-level buffer cylinder in a group of first-level buffer cylinders The oil outlet of 13 is connected with auxiliary braking device, and the oil outlet of all the other first-level buffer oil cylinders 13 is connected with the inner cavity of two capsule bodies 2 respectively by the mode of even distribution. The automobile chassis 10 is also provided with secondary buffer oil cylinders 5 corresponding to the number of driven oil cylinders 8, and the front end of each secondary buffer oil cylinder 5 piston rod 5a is connected with a baffle plate 4, and the baffle plate 4 is positioned at the rear of the bumper 3, each two The oil outlet of the stage buffer oil cylinder 5 is connected with the oil inlet of each driven oil cylinder 8 in one-to-one correspondence. In this embodiment, the two capsules 2 are fixed to the front ends of the primary buffer cylinder 13 and the secondary buffer cylinder 5 , and the piston rod 13 a of the primary buffer cylinder 13 and the piston rod 5 a of the secondary buffer cylinder 5 pass through the capsule 2 .

In this embodiment, the auxiliary braking device is the same as the prior art. Its main body is an actuator cylinder 6 , and the front end of the piston rod of the actuator cylinder 6 is connected with a spring 12 and a stopper 11 . When the auxiliary braking device is set, the block 11 abuts against the brake lever 7 of the automobile.

In this embodiment, there are three primary buffer oil cylinders in a group, and the oil outlet of the primary buffer oil cylinder 13 in the middle is connected with the oil inlet of the executive cylinder 6, and the other two Only the oil outlet of the primary buffer oil cylinder 13 is connected with the inner chamber of a capsule body 2 respectively.

In this embodiment, the oil outlet of the primary buffer oil cylinder 13 is connected with the inner cavity of the capsule body 2 through the oil discharge pipe 15, and one end of the oil discharge pipe 15 extending into the capsule body 2 is connected with a nozzle 14, and the nozzle 14 is evenly distributed with orifice. When the spray head 14 sprays the liquid medium, the spray hole on it is equivalent to the damping hole again.

It can be seen from Fig. 1 and Fig. 2 that when the bumper 3 is impacted, firstly, two primary buffer cylinders 13 buffer the bumper 3, and the other primary buffer cylinder 13 drives the actuator cylinder 6 and the stopper 11 pushes the brake The rod 7 realizes braking, and at the same time, the liquid medium in the two first-stage buffer cylinders 13 will be sprayed into the two capsules 2, and the spraying process is the process of energy release, which can prevent the vehicle from rebounding and prevent the driver and passengers from being hit twice. The capsule body 2 bulges under the action of the injected liquid medium, which is equivalent to installing an airbag on the vehicle; then, the secondary buffer cylinder 5 buffers the bumper 3 again, and the secondary buffer cylinder 5 will make the driven cylinder 8 The driving seat 9 and the people on it recline, and the receding increases the buffer space, and further increases the safety of the drivers and passengers.
