[0002] Two-wheeled vehicles are a widely used mode of transportation with advantages such as strong applicability and maneuverability. In order to maintain the balance of two-wheeled vehicles when parked, the bottom of the vehicle body is usually connected to a single or double stand. When the single or double stand is folded up, the support tube will directly make hard contact with and impact the plastic guard plate at the bottom of the vehicle body, causing scratches or even cracks on the surface of the guard plate, resulting in damage to the two-wheeled vehicle body. The impact will also produce abnormal noise, affecting the user's driving experience. Utility Model Content

The anti-collision block is disposed on the side of the support pipe near the bottom of the vehicle body. When the support pipe is retracted, the anti-collision block abuts against the bottom of the vehicle body and generates elastic deformation to absorb collision energy, thereby avoiding hard contact collision between the support pipe and the bottom of the vehicle body.
[0006] In some embodiments, the anti-collision block is fixedly connected to the branch pipe by bolts or adhesive.
[0007] In some embodiments, the anti-collision block is connected to the branch pipe by means of a clamp.

[0024] The purpose of this utility model is to provide a vehicle body support anti-collision device, a vehicle body support, and a two-wheeled vehicle, which can reduce damage to the two-wheeled vehicle body and improve the user's vehicle experience.
[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0026] Example 1
[0027] This embodiment provides a vehicle body support anti-collision device, such as Figures 1-4 As shown, it includes an elastic anti-collision block 1, which is set on the side of the branch pipe 2 near the bottom of the vehicle body. When the branch pipe 2 is retracted, the anti-collision block 1 abuts against the bottom of the vehicle body and generates elastic deformation to absorb collision energy, thereby avoiding hard contact between the branch pipe 2 and the bottom of the vehicle body, avoiding scratches on the surface of the guard plate or even cracking of the guard plate, thereby reducing damage to the two-wheeled vehicle body, reducing abnormal noise caused by impact, and improving the user's driving experience.
[0028] In some embodiments of this example, the anti-collision block 1 is fixedly connected to the branch pipe 2 by bolts or adhesive. When using a bolt connection, the bolt is passed through the mounting hole 11 on the anti-collision block 1 and tightened onto the side wall of the branch pipe 2 to fix the anti-collision block 1. The anti-collision block 1 has at least two mounting holes 11, and the vehicle support has threaded holes 21 that are compatible with the bolts. The provision of at least two mounting holes 11 can prevent the elastic body from rotating or shifting during use. The bolt connection method is simple, reliable, and easy to install and disassemble. When using an adhesive connection, a strong adhesive is applied to the side of the anti-collision block 1 near the branch pipe 2, and the anti-collision block 1 is adhered to the side wall of the branch pipe 2.
[0029] In some implementations of this embodiment, such as Figure 4 As shown, the anti-collision block 1 is connected to the branch pipe 2 by the clamp 3. The connection method of the anti-collision block 1 being fitted onto the branch pipe 2 can avoid the weakening of the side wall of the branch pipe 2 by the bolt hole and ensure the strength of the branch pipe 2.
[0030] In some implementations of this embodiment, such as Figure 4 As shown, the clamp 3 includes a retaining ring 31 and a retaining ear 32. The middle part of the retaining ring 31 is fixedly connected to the anti-collision block 1. The two ends of the retaining ring 31 are respectively fixedly connected to the retaining ear 32. The retaining ear 32 has a bolt hole for the bolt to pass through. The bolt can connect the two retaining ears 32 to fit the retaining ring 31 onto the branch pipe 2, so as to fix the anti-collision block 1 onto the branch pipe 2.
[0031] In some implementations of this embodiment, such as Figure 1 As shown, the side of the anti-collision block 1 closest to the branch pipe 2 is curved to fit the side wall of the branch pipe 2. When using adhesive fixing, the fit of the anti-collision block 1 to the side wall of the branch pipe 2 can improve the stability of the connection between the anti-collision block 1 and the branch pipe 2.
[0032] In some implementations of this embodiment, such as Figure 2 As shown, the anti-collision block 1 includes an anti-collision block base 12 and an anti-collision pad 13. The anti-collision block base 12 is fixedly connected to the branch pipe 2, and the anti-collision pad 13 is fixedly installed on the side of the anti-collision block base 12 near the bottom of the vehicle body.
[0033] In some implementations of this embodiment, such as Figure 2 As shown, the base 12 of the anti-collision block is made of rubber or silicone. Rubber or silicone materials have good elasticity and toughness, and can produce large deformation when subjected to collision, thereby effectively absorbing collision energy. The anti-collision pad 13 is made of porous sponge. Porous sponge is a flexible material. When it collides with the bottom of the vehicle body, the pores inside the sponge will be compressed or deformed. The flow of gas in the pores will generate frictional resistance. The molecules of the material itself will also generate internal friction due to deformation. All of this energy is consumed in the form of heat energy, thereby further reducing the impact force when the anti-collision block 1 collides with the bottom of the vehicle body.
[0034] In some implementations of this embodiment, such as Figure 3 As shown, the anti-collision block base 12 is fixedly connected to the branch pipe 2 by bolts. The bolts are passed through the mounting holes 11 on the anti-collision block base 12 and tightened into the threaded holes 21 on the side wall of the branch pipe 2 to fix the anti-collision block 1. Then, the anti-collision pad 13 is pasted onto the anti-collision block base 12 with strong glue to cover the bolt mounting holes 11 on the anti-collision block base 12.
[0035] In some embodiments of this example, the anti-collision block base 12 is provided with reinforcing ribs inside. The reinforcing ribs are distributed in a grid pattern and are made of nylon material. The reinforcing ribs can enhance the structural strength of the anti-collision block base 12 and prevent the anti-collision block base 12 from tearing or breaking during long-term use, while not affecting its elastic properties. Nylon material has high strength and toughness and is suitable as a material for reinforcing ribs.
[0036] In some embodiments of this example, the edge of the anti-collision block 1 is provided with rounded corners with a radius of 2-5mm. The rounded corner structure can reduce scratches to the human body or other parts during the installation and use of the anti-collision block 1. At the same time, the elastic anti-collision block 1 will be repeatedly subjected to force and deformation during use, which is a cyclic load and is prone to fatigue. When the edge of the anti-collision block 1 is a sharp corner, it is easy to cause uneven stress distribution, excessive local stress, exceeding the material fatigue limit, resulting in crack generation and propagation. Therefore, by setting rounded corners on the edge of the anti-collision block 1, stress can be dispersed, stress concentration can be reduced, and the fatigue resistance of the elastic body can be improved.
[0037] In some embodiments of this example, the anti-collision pad 13 is provided with a plurality of grooves, which are evenly distributed. The grooves can provide a larger deformation space when the anti-collision pad 13 deforms, thereby improving the buffering effect and reducing the weight of the anti-collision block 1. The grooves can also store a certain amount of dust and moisture, reducing the direct friction between the surface of the anti-collision pad and the bottom of the vehicle body, thereby reducing the wear of the bottom of the vehicle body by dust and reducing the corrosive effect of moisture on the bottom of the vehicle body.
[0038] Example 2
[0039] This embodiment provides a vehicle body support, such as Figure 1 As shown, it includes a branch pipe 2 and a crash block 1 as in Embodiment 1. The crash block 1 is located on the side of the branch pipe 2 near the bottom of the vehicle body. The end of the branch pipe 2 is rotatably connected to the bottom of the vehicle body. When the branch pipe 2 is retracted, the crash block 1 abuts against the bottom of the vehicle body and generates elastic deformation to absorb collision energy, thereby avoiding hard contact between the branch pipe 2 and the bottom of the vehicle body, avoiding scratches on the surface of the guard plate or even cracking of the guard plate, thereby reducing damage to the two-wheeled vehicle body, reducing abnormal noise caused by impact, and improving the user's driving experience.
[0040] In some embodiments of this example, the vehicle body support includes a single support tube, which is lighter and occupies less space. The number of anti-collision blocks is one, which is set on the side of the single support tube near the bottom of the vehicle body.
[0041] In some implementations of this embodiment, such as Figure 1 As shown, the vehicle body support includes a double-bracing pipe, with the two pipes forming a triangular or symmetrical support structure, which can effectively disperse lateral forces and has a significantly better anti-roll capability than a single-bracing pipe, greatly improving overall stability. There are two anti-collision blocks 1, which are symmetrically arranged on the side of the double-bracing pipe near the bottom of the vehicle body.
[0042] In some embodiments of this example, an elastic reset member is also included. One end of the elastic reset member is hinged to the branch pipe 2, and the other end is hinged to the bottom of the vehicle body. When the branch pipe 2 is supported on the ground, the elastic reset member is stretched. When the branch pipe 2 is retracted, the elastic reset member can provide a restoring force to the branch pipe 2 and keep the branch pipe 2 in the retracted state. Specifically, the elastic reset member is a tension spring.
[0043] In some embodiments of this example, the vehicle body support also includes a limiting structure. The limiting structure is fixedly installed at the bottom of the vehicle body and is coplanar with the virtual plane of the area swept by the branch pipe 2 when it is retracted. When the branch pipe 2 is in the retracted state, the limiting structure abuts against the branch pipe 2 to limit the rotation angle of the branch pipe 2 when it is retracted.
[0044] In some embodiments of this example, the vehicle support provided in this example is applicable to various vehicle types such as bicycles, electric bicycles, and motorcycles.
[0045] Example 3
[0046] This embodiment provides a two-wheeled vehicle, including a frame, a handlebar set at the front end of the frame, a seat, and a body support as in Embodiment 2. When the branch tube 2 is retracted, the anti-collision block 1 abuts against the bottom of the vehicle body and generates elastic deformation to absorb collision energy, thereby avoiding hard contact collision between the branch tube 2 and the bottom of the vehicle body, avoiding scratches or even cracks on the surface of the protective plate, reducing damage to the two-wheeled vehicle body, reducing abnormal noise caused by impact, and improving the user's driving experience.
[0047] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
