[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods:

[0023] like Figure 1-5 As shown, the utility model provides a driving shock absorption and anti-collision device, including a fixed beam 1 and a front anti-collision beam 2, one end of the fixed beam 1 is fixedly installed with a sleeve 101, one end of the fixed beam 1 is fixedly connected to the support beam 3 through a plurality of connecting seats 4 and a welding plate 401, one end of the front anti-collision beam 2 is fixedly connected to the reinforcement beam 11 through a plurality of fixing bolts 12, one end of the front anti-collision beam 2 is fixedly installed with a steel plate 5, one end of the steel plate 5 is fixedly installed with a fixed shaft 6, and two inflatable components 8 are arranged between the steel plate 5 and the support beam 3, one end of the support beam 3 is provided with two cushioning airbags 9, the inflatable component 8 includes an air cylinder 802 and a piston core rod 804, one end of the fixed shaft 6 is fixedly connected with a connecting rod 803, and a connecting rod 804 is fixedly installed with a connecting rod 805. The outer walls of the connecting shaft 7 and the fixed shaft 6 are sleeved with a compression spring 1 600, and a compression spring 2 700 is arranged between the connecting shaft 7 and the sleeve 101. One end of the compression spring 1 600 is connected to one end of the support beam 3, and the other end is connected to one end of the steel plate 5. One end of the compression spring 2 700 is connected to the fixed beam 1, and the other end is connected to the connecting shaft 7. The connecting shaft 7 is slidably fitted with the sleeve 101, and the fixed shaft 6 and the connecting shaft 7 are both slidably fitted with the support beam 3. Several positioning holes 100 are provided at one end of the fixed beam 1 and the support beam 3. A fastening bolt 400 is threadedly connected between the connecting seat 4 and the positioning hole 100, and the welding plate 401 is fixedly connected to the two positioning holes 100.

[0024] When the front of the vehicle is hit, the impact force it receives can be applied to the surface of the reinforcing beam 11, which then causes the reinforcing beam 11 to push the front anti-collision beam 2 to move. When the front anti-collision beam 2 moves, it drives the steel plate 5 and the fixed shaft 6 to move. When the fixed shaft 6 moves, it drives the connecting shaft 7 to move. When the fixed shaft 6 moves, it squeezes the compression spring 1 600 through the steel plate 5 and the support beam 3. When the connecting shaft 7 moves, it cooperates with the fixed beam 1 and squeezes the compression spring 2 700, thereby exerting a buffering effect on the front anti-collision beam 2. When the impact force received by the equipment is large, when the front anti-collision beam 2 continues to be pushed by the impact force, the steel plate 5 can squeeze the buffer airbag 9. Through various buffering functions, the anti-collision effect of the equipment can be effectively improved, and the safety performance of the vehicle can be improved.

[0025] The cushioning airbag 9 and the piston core rod 804 are prior art and will not be explained here.

[0026] like Figure 3-4 As shown, in one embodiment, the inflation component 8 also includes a push rod 801, which is fixedly connected to one end of the steel plate 5 and slidingly cooperates with the air cylinder 802. The air cylinder 802 is fixedly connected to one end of the support beam 3. The piston core rod 804 is arranged on the inner wall of the air cylinder 802, and the ventilation end is connected to the buffer airbag 9. The inflation component 8 also includes a plurality of sealing sleeves 803, and the plurality of sealing sleeves 803 are fixedly sleeved on the air cylinder 802 and fixedly connected to the support beam 3.

[0027] First, install the device at the front end of the vehicle, and then fix the fixed beam 1 in front of the vehicle. When the front of the vehicle is slightly collided, the impact force it receives can be applied to the surface of the reinforcing beam 11, and then the reinforcing beam 11 pushes the front anti-collision beam 2 to move. When the front anti-collision beam 2 moves, it drives the steel plate 5 and the fixed shaft 6 to move. When the steel plate 5 moves, it drives the two push rods 801 to move, and then the push rod 801 slides in the air cylinder 802 and squeezes the gas in the air cylinder 802, so that the gas passes through the air cylinder 802 and the piston core rod 804 into the buffer airbag 9, so that the device can recover kinetic energy when it is slightly collided, and there is no need to manually replenish the airbag, thereby improving applicability.

[0028] The following is a detailed description of the working principle of the driving shock absorption and anti-collision device:

[0029] First, the device is installed at the front end of the vehicle, and then the fixed beam 1 is fixed to the front of the vehicle. When the front of the vehicle is slightly hit, the impact force it receives can be applied to the surface of the reinforcing beam 11, and then the reinforcing beam 11 pushes the front anti-collision beam 2 to move. When the front anti-collision beam 2 moves, it drives the steel plate 5 and the fixed shaft 6 to move. When the steel plate 5 moves, it drives the two push rods 801 to move, and then the push rods 801 slide in the air cylinder 802 and squeeze the gas in the air cylinder 802, so that the gas passes through the air cylinder 802 and the piston core rod 804 into the buffer airbag 9. In this way, the device can recover kinetic energy when it is slightly hit, and there is no need to manually inflate the airbag, which improves applicability.

[0030] When the fixed shaft 6 moves, it drives the connecting shaft 7 to move. When the fixed shaft 6 moves, it squeezes the compression spring 1 600 through the steel plate 5 and the support beam 3. When the connecting shaft 7 moves, it cooperates with the fixed beam 1 and squeezes the compression spring 2 700, thereby exerting a buffering effect on the front anti-collision beam 2. When the impact force applied to the equipment is large, when the front anti-collision beam 2 continues to be pushed by the impact force, the steel plate 5 can squeeze the buffer airbag 9. Through various buffering functions, the anti-collision effect of the equipment can be effectively improved, and the safety performance of the vehicle can be improved.

[0031] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
