When household appliances have been fully popularized, the focus of residents' consumption will shift to large-value housing and cars. It is under this consumption trend that the automobile industry has maintained a relatively high growth rate in recent years. The increase in per capita car ownership has led to an increase in the incidence of traffic accidents year by year. China has 500,000 traffic accidents every year, and the number of deaths due to traffic accidents exceeds 100,000, which is equivalent to a small county and ranks first in the world. According to statistics, one person dies every 5 minutes due to wheels, and one person is disabled every 1 minute due to traffic accidents. The economic losses caused by traffic accidents each year amount to hundreds of billions of yuan.

When a traffic accident occurs, especially when a collision occurs, the quality of the vehicle's anti-collision beam is particularly important to the protection effect of the vehicle. The two ends of the existing automobile anti-collision beam are connected to low-speed energy absorption boxes with very low yield strength, and then connected to the longitudinal beam of the vehicle body by bolts. The low-speed energy absorption box can effectively absorb the collision energy when the vehicle collides at a low speed, and minimize the damage to the longitudinal beam of the vehicle body caused by the impact force.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

As shown in Figures 1 to 4, a double-beam high-collision resistance automobile comprises an automobile main beam 1, a driving device 7 is installed in the middle of the automobile main beam 1, and the driving device 7 is used to drive the automobile to move forward. A sub-beam 3 is fixed above the automobile main beam 1 by riding bolts, and a rubber pad 2 is arranged between the sub-beam 3 and the automobile main beam 1. When a collision occurs, the sub-beam 3 can slide relative to the automobile main beam 1 to buffer the impact force and reduce damage to the automobile frame. A mounting bracket 4 is welded on the side wall of the front end of the sub-beam 3, and an anti-collision protection device 5 is fixed on the mounting bracket 4 by bolts. The anti-collision protection device 5 is used to To protect the car and the driver, the cab 6 is fixed to the anti-collision protection device 5 by screws. The anti-collision protection device 5 includes a rear limit frame 51 and a front impact beam 55. A friction sleeve 52 is nested at the front end of the rear limit frame 51, and a front buffer column 53 is nested at the other end of the friction sleeve 52. An elastic buffer member 57 is arranged between the rear limit frame 51 and the front buffer column 53. The front impact beam 55 is nested at the front end of the rear limit frame 51. Two movable collision blocks 54 are symmetrically arranged inside the front impact beam 55 corresponding to the position of the front buffer column 53, and an elastic limit member 56 is arranged on the outward side of the two movable collision blocks 54.

In this embodiment, the rear limit frame 51, the friction sleeve 52 and the front impact beam 55 are made of steel. There are two rear limit frames 51 and two friction sleeves 52 respectively and they are symmetrically welded to the front end of the automobile frame. The rear limit frame 51 is used for positioning and limiting the buffer position.

In this embodiment, the front buffer column 53 is slidably installed inside the friction sleeve 52. The front buffer column 53 includes a wooden inner core 531 and a steel outer sleeve 532 wrapped on the outside. A hose sleeve that increases friction is installed between the front buffer column 53 and the friction sleeve 52. The design of wood wrapped with steel plate can reduce the weight of the front buffer column 53 while ensuring strength, thereby avoiding affecting the weight of the vehicle.

In this embodiment, the elastic buffer 57 includes but is not limited to a spring pad or an elastic shock-absorbing rubber pad. There is at least one elastic buffer 57, and the elastic buffer 57 is used to alleviate impact force. When an impact occurs, the elastic buffer 57 contracts to reduce the impact force.

In this embodiment, at least one buffer block 58 is arranged between the rear limit frame 51 and the front buffer column 53. The buffer block 58 is made of wood. Elastic buffer members 57 are arranged between the multiple buffer blocks 58, between the buffer block 58 and the rear limit frame 51, and between the buffer block 58 and the front buffer column 53. The wooden buffer blocks 58 can also play a role in buffering impact force. The buffer blocks 58 and the elastic buffer members 57 work together to resist larger impacts and improve performance.

In this embodiment, the front end of the front buffer column 53 is a conical structure, and the two movable collision blocks 54 corresponding to the front buffer column 53 have an oblique opening on the opposite side thereof that matches the cone of the front buffer column 53. When a collision occurs, when the front buffer column 53 is inserted between the two movable collision blocks 54, the movable collision blocks 54 will generate resistance to the front buffer column 53, thereby transmitting the impact force step by step, and finally weakening and eliminating the impact force.

In this embodiment, the elastic limiter 56 is a compression spring, and the elastic limiter 56 is in a compressed state, ensuring that a greater force is required for the two movable collision blocks 54 to move to both sides, and the movable collision blocks 54 can be restored to their original positions after the collision to avoid affecting the next use.

In this embodiment, two sliding sleeves are welded at both ends of the front impact beam 55 and are slidably mounted on the front buffer column 53. The front impact beam 55 and the friction sleeve 52 are connected and fixed by a soft connection. One end of the soft connection is directly fixed on the front impact beam 55 or on the side wall of the sliding sleeve, and the other end of the soft connection is fixed on the automobile chassis or the friction sleeve 52. The front impact beam 55 can be connected to the automobile chassis or the friction sleeve 52 as a whole to prevent the front impact beam 55 from falling off the front buffer column 53 when the automobile is driving or in an impact.

The working principle of the present invention is as follows: when in use, the device is installed on the chassis of the automobile. When the vehicle collides during driving, the front impact beam 55 moves along the axis of the front buffer column 53. At this time, the conical structure at the front end of the front buffer column 53 is inserted into the oblique opening between the two movable collision blocks 54, pushing the two movable collision blocks 54 to move to both sides. The movable collision blocks 54 give the front buffer column 53 a resistance under the reaction of the elastic limiter 56, preventing the front buffer column 53 from continuing to move forward. After the front buffer column 53 is subjected to the resistance, it shrinks into the friction sleeve 52, and the friction sleeve 52 and the front buffer column 53 are When relative sliding occurs, friction is generated to cushion the impact on the front buffer column 53. At the same time, the elastic buffer member 57 between the rear limit frame 51 and the friction sleeve 52 is compressed and collides with the buffer block 58, which also performs buffering, and finally completes the anti-collision work of the car. When the collision is over, the pressure on the elastic buffer member 57 disappears and it begins to rebound, pushing the front buffer column 53 back to its original position. At the same time, the movable collision block 54 is closed again under the action of the elastic limit member 56, so that the front buffer column 53 withdraws from between the two movable collision blocks 54, so that the front impact beam 55 returns to its original position and waits to be used again.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
