[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 technical field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 5 The energy-absorbing buffer anti-collision pad of this embodiment includes a honeycomb aluminum box 1, a bracket 2 installed on both sides of the honeycomb aluminum box 1 and a buffer aluminum plate 3 installed at the outer end of the bracket 2. A mounting bracket 4 is installed at one end of the honeycomb aluminum box 1, and a plurality of through-holes 7 are opened on the side wall of the mounting bracket 4. A buffer unit 5 is installed between the mounting bracket 4 and the honeycomb aluminum box 1. The buffer unit 5 includes a plurality of sliding rods 51 fixedly installed on the inner wall of the mounting bracket 4. The outer wall of the sliding rod 51 is slidably connected to two sliding blocks 52. The end plate of the honeycomb aluminum box 1 away from the buffer aluminum plate 3 is fixed to the sliding block 52. The outer wall of the sliding rod 51 is sleeved with two springs 53. One end of the two springs 53 is fixedly abutted against the inner top wall and the inner bottom surface of the mounting bracket 4 respectively, and the other end of the two springs 53 is abutted against the side wall of one of the adjacent sliding blocks 52. A tensioning unit 6 for tightening the honeycomb aluminum box 1 is installed between the honeycomb aluminum box 1 and the mounting bracket 4.

[0024] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown, the energy-absorbing and buffering anti-collision pad structure in the present invention is similar to the existing energy-absorbing and buffering anti-collision pad structure. The main improvement of the present invention is that the anti-collision pad is stably installed on the car, the bumps caused by the car are buffered, the strength of the anti-collision pad installation is improved, and it is suitable for long-term use; the honeycomb aluminum box 1, bracket 2 and buffer aluminum plate 3 required in the present invention are all existing technologies. When the anti-collision pad is installed, bolts are passed through the through holes 7 on the mounting frame 4 and connected to the car. When the car is driving, if bumps occur, the honeycomb aluminum box 1 drives the slider 52 to slide on the slide rod 51, and the slide rod 51 is supported by the mounting frame 4. When the two sliders 52 on the slide rod 51 move, they are buffered by the elastic force of the springs 53 on their side walls. The two springs 53 on the slide rod 51 buffer each other, thereby unloading the bumps, avoiding the honeycomb aluminum box 1 from being damaged by hard swinging due to bumps, and improving the stability and strength of the anti-collision pad installation.

[0025] like Figure 5 As shown, the buffer unit 5 also includes a plurality of limit plates 54 fixedly connected to the inner wall of the mounting frame 4, and the slider 52 is slidably connected between two adjacent limit plates 54; when the honeycomb aluminum box 1 drives the two sliders 52 to slide on the outer wall of the slide rod 51, the slider 52 slides between the two limit plates 54, and the two limit plates 54 restrict the slider 52 so that the slider 52 does not rotate, thereby maintaining the stability of the honeycomb aluminum box 1.

[0026] like Figure 4 and Figure 5 As shown, one end plate of the honeycomb aluminum box 1 is threadedly connected to multiple sliders 52 through multiple bolts, and the bolts used to connect the honeycomb aluminum box 1 and the sliders 52 are staggered with the slide rods 51; the honeycomb aluminum box 1 is fixed to the sliders 52 by bolts, which facilitates the disassembly and assembly of the honeycomb aluminum box 1. After the honeycomb aluminum box 1, the bracket 2 and the buffer aluminum plate 3 are damaged, they can be easily replaced.

[0027] like Figure 1 、 Figure 2 and Figure 5 As shown, the tensioning unit 6 includes two connecting rings 62 installed on the upper surface of the honeycomb aluminum box 1 close to the buffer aluminum plate 3 and two vertical rods 61 fixed to the upper end surface of the mounting frame 4 by bolts. A tensioning rope 63 is installed on the vertical rod 61, and the other end of the tensioning rope 63 is connected to one of the adjacent connecting rings 62; the vertical rod 61 fixes one end of the tensioning rope 63, and the other end of the tensioning rope 63 applies tension to the end of the honeycomb aluminum box 1 away from the mounting frame 4 through the connecting ring 62, so that the outer end of the honeycomb aluminum box 1 is supported by tension, reducing the phenomenon of overall bending of the anti-collision pad due to swinging of the outer end, and further improving stability and strength.

[0028] like Figure 2 and Figure 3As shown, the tensioning unit 6 also includes a clamping block 64 installed on the upper end of the vertical rod 61 by bolts and nuts, and arc grooves 65 are provided on the bottom surface of the clamping block 64 and the upper end surface of the vertical rod 61. The clamping block 64 cooperates with the vertical rod 61 and the two arc grooves 65 to clamp and fix the tensioning rope 63; the tensioning rope 63 is clamped and fixed by the clamping block 64 in cooperation with the arc grooves 65 on its bottom surface and the arc grooves 65 on the vertical rod 61, and the clamping block 64 is locked with the vertical rod 61 by bolts and nuts, which is convenient for fixing the tensioning rope 63, facilitating the adjustment of the tensioning rope 63, and improving adaptability.

[0029] like Figure 3 As shown, the tensioning unit 6 also includes a tooth opening 67 opened on the inner wall of the arc groove 65. There are multiple tooth openings 67, and multiple tooth openings 67 are evenly opened on the inner wall of the arc groove 65. The tensioning rope 63 is firmly clamped and fixed by the tooth openings 67 on the inner wall of the arc groove 65, thereby improving the firmness of the clamping of the tensioning rope 63.

[0030] like Figure 4 As shown, the tensioning unit 6 also includes triangular support blocks 66 fixedly installed on both sides of the lower end of the vertical rod 61, and the bottom surface of the triangular support block 66 is against the upper end surface of the mounting frame 4; the triangular support block 66 can be used to support the vertical rod 61 to improve the strength of the vertical rod 61.

[0031] The implementation steps in this embodiment are as follows: when installing the anti-collision pad, the bolts are passed through the through holes 7 on the mounting frame 4 and connected to the car. When the car is driving, if bumps occur, the honeycomb aluminum box 1 drives the slider 52 to slide on the slide bar 51, and the slide bar 51 is supported by the mounting frame 4. When the two sliders 52 on the slide bar 51 move, the elastic force of the springs 53 on their side walls is used for buffering. The two springs 53 on the slide bar 51 buffer each other, thereby unloading the force of the bumps, avoiding the honeycomb aluminum box 1 from being damaged by the hard swing caused by the bumps, thereby improving the stability and strength of the anti-collision pad installation; at the same time, the mounting frame 4 supports the vertical rod 61, and the clamping block 64 at the upper end of the vertical rod 61 clamps one end of the tensioning rope 63, and the other end of the tensioning rope 63 applies tension to the end of the honeycomb aluminum box 1 away from the mounting frame 4 through the connecting ring 62, thereby making the outer end of the honeycomb aluminum box 1 supported by tension, reducing the phenomenon of overall bending of the anti-collision pad caused by the swing of the outer end, and further improving the stability and strength.

[0032] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
