[0002] At present, there is a general lack of dedicated anti-collision devices for the rear of large vehicles. The reason is that the rear of large vehicles is usually higher and the body structure is complex, so the existing anti-collision devices for large vehicles installed with anti-collision beams will increase the weight and complexity of the body. In addition, the manufacturing process of large vehicles has taken safety factors into consideration and improved the overall safety performance by changing the body structure. Therefore, general anti-collision devices for large vehicles can no longer meet the anti-collision requirements. Large vehicles need devices with better anti-collision performance at the rear.
[0003] With the frequent occurrence of traffic accidents and the improvement of safety awareness, the demand for anti-collision devices is gradually increasing. Ensuring the safety of drivers and passengers has become the responsibility of automobile manufacturers. Therefore, some large automobile manufacturers have begun to explore installing additional anti-collision devices at the rear to further protect the safety of drivers and passengers.

DETAILED DESCRIPTION
[0022] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0023] like Figure 1 The vehicle safety anti-collision device shown in the figure comprises a front anti-collision body 100, a rear anti-collision body 200 and a deformation beam group 300 connected between the front anti-collision body 100 and the rear anti-collision body 200; the front anti-collision body 100 is an anti-collision component at the front of the vehicle, such as Figure 2 As shown, it includes a U-shaped front anti-collision hollow block 110 and a front-stage connecting plate 120, and a plurality of energy absorbing springs 130 are arranged between the U-shaped front anti-collision hollow block 110 and the front-stage connecting plate 120 along the longitudinal beam direction of the vehicle; the U-shaped front anti-collision hollow block 110 includes an impact portion 111 located in the middle and energy absorbing portions 112 located at both ends, the energy absorbing portion 112 and the impact portion 111 are interconnected, and the energy absorbing portion 112 and the impact portion 111 are integrally formed with a steel structure to form a U-shaped channel inside, wherein the impact portion 111 1 is arranged in the horizontal direction as the crossbeam frame of the U-shaped front anti-collision hollow block 110, the front end face and the rear end face of the impact part 111 are both planes, providing a stable support surface, and the energy absorbing part 112 is arranged in the longitudinal direction as the longitudinal beam frame of the U-shaped front anti-collision hollow block 110, and then the energy absorbing spring 130 is used to absorb the collision energy and reduce the impact of the collision on the vehicle and the occupants. It should be noted that in order not to occupy more space, multiple energy absorbing springs 130 are arranged in parallel in the space surrounded by the U-shaped front anti-collision hollow block 110 and the front-stage connecting plate 120. Among them, the U-shaped front anti-collision hollow block 110 is a key component of the front-stage anti-collision body 100, and its function is to absorb and disperse the impact energy during the collision and reduce the damage caused by the collision to the vehicle and the occupants. The impact part is located in the middle, and as a crossbeam frame, it can withstand the impact force of the collision. The energy absorbing part is located at both ends, and as a longitudinal beam frame, it improves the collision energy absorption performance through the design of longitudinal energy absorption. When a collision occurs, the impact force will be transmitted to the impact part of the U-shaped front anti-collision hollow block. Due to the longitudinal design of the impact part, it can absorb and disperse the collision energy, reducing the impact of the collision on the vehicle structure and occupants. Due to the hollow structure, the U-shaped front anti-collision hollow block can provide strong energy absorption capacity while reducing the weight of the device.
[0024] The rear stage anti-collision body 200 includes: Figure 2-4 The anti-collision block 201 and the rear-stage connecting plate 202, the rear-stage connecting plate 202 and the front-stage connecting plate 120 are arranged in parallel front and back, which can enhance the structural stability of the entire anti-collision body. The lower bottom surface of the anti-collision block 201 is connected to the rear-stage connecting plate 202; a plurality of connecting rods 203 are connected to the rear-stage anti-collision body 200 along the longitudinal beam direction of the vehicle toward the front of the vehicle, and the rear-stage anti-collision body is installed at the rear of the vehicle through the connecting rods 203. The connecting rods 203 can be fixedly connected to the chassis crossbeam of the automobile, either by bolts or by welding, and bolt holes can be reserved on the connecting rods 203.
[0025] The anti-collision block 201 is trapezoidal in shape. As the main energy-absorbing part, it can absorb and disperse the collision energy and reduce the impact of the collision on the rear structure of the vehicle and the passengers in the vehicle. In this embodiment, the anti-collision block 201 is relatively flat as a whole. The upper bottom of the anti-collision block 201 faces the front connecting plate 120 of the vehicle. The cross-sectional area of the anti-collision block 201 gradually increases from the upper bottom to the lower bottom. The upper bottom is parallel to the front connecting plate 120 and there is a gap between the upper bottom and the front connecting plate 120. Therefore, when a collision occurs, the impact force of the initial contact point is first transmitted to the upper bottom surface of the anti-collision block, and then as the collision continues to advance, the impact force gradually diffuses to the lower bottom surface. The design of the trapezoidal hollow body provides energy absorption areas in different areas, so that the collision energy is gradually dispersed and absorbed, reducing the impact on the rear structure of the vehicle and the passengers. At the same time, the trapezoidal design of the anti-collision block also helps to prevent excessive compression. During the collision, the anti-collision block will be subjected to pressure and deformation, but the upper bottom surface of the trapezoidal design can provide a certain resistance to avoid excessive compression. This helps maintain the crash bar's energy-absorbing properties and shape stability, ensuring it continues to work effectively after multiple collisions or repeated use.
[0026] The deformable beam group 300 includes an arc beam 301 and a straight beam 302, and the arc beam 301 and the straight beam 302 are connected between the front-stage connecting plate 120 and the rear-stage connecting plate 202. There are two arc beams 301 on the upper side and the lower side of the anti-collision block 201, and the two arc beams 301 on the same side of the anti-collision block 201 are bent in opposite directions along the horizontal plane, and the straight beam 302 is located on the midline of the two arc beams 301 on the same side. The deformable beam group 300 includes an arc beam 301 and a straight beam 302, and the arc beam and the straight beam are connected between the front-stage connecting plate 120 and the rear-stage connecting plate 202. There are two curved beams on the upper and lower sides of the anti-collision block 201. In addition to connecting the front-stage anti-collision body 100 and the rear-stage anti-collision body 200, the arrangement of the curved beam and the straight beam can also provide a larger energy absorption area. When a collision occurs, the curved beam and the straight beam bear the impact force, and absorb and disperse the impact energy through deformation, thereby reducing the impact of the collision on the vehicle structure and occupants. At the same time, the existence of the curved beam and the straight beam enhances the structural rigidity and stability of the entire anti-collision device. They can better resist force and vibration during a collision, ensuring that the device maintains a correct working state. Among them, it should be noted that the design of the curved beam enables it to better adapt to the deformation requirements during the collision process, and its curved shape enables the curved beam to have a higher deformation capacity, thereby providing greater impact absorption and collision energy dispersion capabilities.
[0027] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
