[0051] The two buffer components 2 are in contact, that is, Figure 2 As shown, the second serpentine rods 22 included in the two buffer assemblies 2 are in contact with each other, that is, the two second serpentine rods 22 between the two elastic support members 24 are in contact with each other.

[0052] The bent rod 23 includes a plurality of U-shaped portions 231, which are arranged in parallel and at intervals, and the U-shaped portions 231 located on the two sides are respectively connected to the ends 233, and the two ends 233 are respectively arranged on the two support seats 1; a connecting portion 232 is connected between each two adjacent U-shaped portions 231, and all the U-shaped portions 231, all the connecting portions 232 and the two ends 233 are an integrally formed structure; Figure 4 As shown, the first serpentine rod 21 contacts each connecting portion 232 , and a triangle structure is formed between each connecting portion 232 and the first serpentine rod 21 ; meanwhile, the second serpentine rod 22 contacts each U-shaped portion 231 , and a triangle structure is formed between each U-shaped portion 231 and the second serpentine rod 22 .

[0053] The first serpentine rod 21 , the second serpentine rod 22 and the bent rod 23 are all made of metal, such as steel or copper.

[0054] See also Figure 5-Figure 6The elastic support member 24 includes a base plate 241, and the two ends of the base plate 241 are respectively arranged on the two support seats 1; two support wing plates 242 are arranged on the base plate 241, and the two support wing plates 242 are symmetrically arranged. The two support wing plates 242 and the base plate 241 adopt an integrally formed structure, and the support wing plates 242 and the base plate 241 are made of metal, such as steel or copper; the support wing plate 242 is composed of an arc portion 2421 and an inclined portion 2422, the arc portion 2421 is connected to the base plate 241, and the inclined portion 2422 is connected to one end of the arc portion 2421 away from the base plate 241; in addition, the two first serpentine rods 21 are respectively in contact with the two inclined portions 2422, and the inclination angle of the inclined portion 2422 is consistent with the inclination angle of the first serpentine rod 21.

[0055] See also Figure 1-Figure 7 In this embodiment, the two support seats 1 are used to be installed and fixed on the housing of the electric tricycle, and the first serpentine rod 21 is close to or in contact with the U-shaped bend of the front bumper of the electric tricycle. The first serpentine rod 21 is located on the outside of the front bumper of the electric tricycle (that is, the side of the front bumper of the electric tricycle away from the housing of the electric tricycle), that is, Figure 7 As shown; when the front bumper of the electric tricycle is hit, the front bumper of the electric tricycle will squeeze the first serpentine rod 21, the first serpentine rod 21 will be deformed, and the first serpentine rod 21 will squeeze the bent rod 23 and the second serpentine rod 22, thereby causing the second serpentine rod 22 and the bent rod 23 to deform. Since the first serpentine rod 21 and the second serpentine rod 22 both adopt a serpentine structure, and the bent rod 23 is composed of a plurality of U-shaped portions 231 and a plurality of connecting portions 232, it is convenient for the first serpentine rod 21, the second serpentine rod 22 and the bent rod 23 to elastically deform as a whole, rather than only the impacted portion being deformed, thereby effectively mitigating and absorbing the impact energy; since a triangular structure is formed between each connecting portion 232 and the first serpentine rod 21, each U-shaped portion 231 and A triangular structure is also formed between the second serpentine rods 22. Therefore, while mitigating and absorbing the impact energy, the first serpentine rod 21, the second serpentine rod 22 and the bent rod 23 are spliced ​​to form a stable structure, thereby improving the anti-destruction capabilities of the first serpentine rod 21, the second serpentine rod 22 and the bent rod 23, thereby improving the protection of the tricycle shell and the people inside the vehicle; in addition, since the first serpentine rod 21 is arranged obliquely, the triangular structure formed by the splicing of the first serpentine rod 21 and the connecting portion 232 and the triangular structure formed by the splicing of the U-shaped portion 231 and the second serpentine rod 22 are not on the same plane, which helps to further improve the anti-destruction capabilities of the first serpentine rod 21, the second serpentine rod 22 and the bent rod 23, that is, further improve the protection of the electric tricycle shell and the people inside the vehicle.

[0056] When the front bumper of the electric tricycle squeezes the first serpentine rod 21 and causes the first serpentine rod 21 to deform, the first serpentine rod 21 will also squeeze the supporting wing plate 242, and the deformation of the supporting wing plate 242 is used to further mitigate and absorb the impact energy; in addition, since the two buffer components 2 are in contact, that is, the two adjacent second serpentine rods 22 in the two buffer components 2 are in contact, the correlation between the two buffer components 2 can be improved, that is, when the front bumper of the electric tricycle is hit, all the buffer components 2 perform buffering and energy absorption, effectively improving the overall buffering energy absorption effect, and also improving the overall anti-destruction ability.

[0057] Embodiment 2

[0058] See also Figure 2-Figure 5 , Figure 8-Figure 10 , this embodiment is based on the first embodiment, and the buffer assembly 2 also includes a U-shaped rod 25, and each base plate 241 is provided with a plurality of U-shaped rods 25, and the plurality of U-shaped rods 25 are arranged in parallel and at intervals along the length direction of the base plate 241, and both ends of the U-shaped rod 25 are arranged on the base plate 241, and the U-shaped rod 25 is entirely covered on the outside of the two supporting wing plates 242; at the same time, the U-shaped rod 25 is arranged at an angle, that is, the U-shaped rod 25 forms a certain angle with the width direction of the base plate 241, and each U-shaped rod 25 close to the two ends is in contact with the first serpentine rod 21 and the second serpentine rod 22 respectively. Specifically, the U-shaped rod 25 close to the two ends is respectively pressed against the V-shaped openings on the first serpentine rod 21 and the second serpentine rod 22. In addition, the U-shaped rod 25 is made of steel or copper.

[0059] The U-shaped rod 25 is close to or in contact with the U-shaped bent pipe of the front bumper of the electric tricycle. The U-shaped rod 25 is located on the outside of the front bumper of the electric tricycle. When the front bumper of the electric tricycle is hit, the front bumper of the electric tricycle can squeeze the U-shaped rod 25, which is convenient for causing the U-shaped rod 25 to deform. The U-shaped rod 25 can cause the supporting wing plate 242 and the first serpentine rod 21 and the second serpentine rod 22 to deform, thereby further improving the linkage between the first serpentine rod 21, the second serpentine rod 22 and the supporting wing plate 242, thereby enhancing the buffering energy absorption effect and anti-destruction ability of the entire shock absorbing device.

[0060] To facilitate the installation and fixation of the U-shaped rod 25 , a plurality of fixing holes 243 are provided on the bottom plate 241 . The fixing holes 243 are matched with the two ends of the U-shaped rod 25 . The two ends of each U-shaped rod 25 are respectively arranged in the corresponding fixing holes 243 .
