Two sliding seats 6 are provided on the movable chassis 1 near the front of the vehicle. A fixed shaft 7 is installed between the two sliding seats 6. A slider 9 is slidably installed on the fixed shaft 7. A first spring 10 coaxial with the fixed shaft 7 is provided between the slider 9 and the sliding seat 6. A first connecting rod 8 is provided between the two sliders 9 and the anti-collision plate 5. The first end of the first connecting rod 8 is rotatably connected to the slider 9, and the second end of the first connecting rod 8 is rotatably connected to the anti-collision plate 5. The sliding seat 6 is slidably installed on the movable chassis 1.
[0021] The force unloading device also includes a movable beam 14, which is slidably mounted on the bottom surface of the movable chassis 1. A slide 22 is provided on the movable chassis 1 near the front of the vehicle. The slide 22 is used to accommodate the movable beam 14. The fixed shaft 7 passes through the first end of the movable beam 14. The second end of the movable beam 14 is fixedly connected to one end of the second spring 17. The other end of the second spring 17 is fixedly connected to the baffle 18. The baffle 18 is fixedly mounted on the lower surface of the movable chassis 1.
[0022] A plurality of slide rails 20 are provided on the bottom surface of the movable chassis 1, and a wedge block 16 is slidably installed on the slide rail 20.

[0023] The working principle of a vehicle collision protection device disclosed by the present invention is as follows: the present invention sets a traditional automobile chassis into two parts, a movable chassis 1 and a mounting frame, the mounting frame is provided with an automobile suspension system, and a frame structure (not shown in the figure) is installed on the movable chassis 1. When the vehicle collides head-on, the anti-collision plate 5 is acted upon by a force, and the anti-collision plate 5 drives the slider 9 to slide on the fixed shaft 7 through the first connecting rod 8. At this time, a buffering effect is achieved by the sliding of the anti-collision plate 5. If the slider 9 slides to the extreme position on the fixed shaft 7 and the vehicle is still subjected to a continuous impact force, the anti-collision plate 5, the sliding seat 6, and the fixed shaft 7 move simultaneously in a direction away from the front of the vehicle, driving the movable beam 14 to slide at the same time. During the sliding process of the movable beam 14, the wedge-shaped The block 16 slides on the slide rail 20, that is, the wedge block 16 slides in the width direction of the vehicle. Since the weight of the structure above the automobile movable chassis 1 is heavier, the wedge block 16 realizes a force unloading process in the process of lifting the movable chassis 1 upward, thereby increasing the rigidity of the automobile. The second spring 17 plays a buffering role. At the same time, when the sensor on the vehicle detects that there is a collision risk in a certain direction, such as when a side collision risk is detected, the piston rod on the telescopic rod 3 arranged inside the longitudinal guide block 4 retracts, and the limit in the width direction of the vehicle is released. Relative sliding occurs between the movable chassis 1 and the mounting frame, which increases the lateral space and weakens the damage to passengers caused by the collision to a certain extent. The limit rod 19 realizes the limit in the length, width and vertical direction of the vehicle.
