Description

Technical Field

[0001] This utility model relates to the field of buffer components, and in particular to a buffer component. Background Technology

[0002] Scooters, electric bikes, or bicycles are vehicles or toys with motor functions, typically consisting of two or three wheels and designed for personal transportation or recreation. A shock-absorbing fork is usually incorporated within the shock-absorbing fork to achieve cushioning. Typically, a buffer component is installed within the shock-absorbing fork. During the up-and-down movement of the elastic component, when an object is impacted or vibrated, it possesses a certain amount of kinetic energy. The shock-absorbing fork converts this kinetic energy into elastic potential energy required for elastic deformation. When the kinetic energy of the moving object decreases to a certain level, the component begins to release its stored elastic potential energy and convert it into deformation energy, thus completely dissipating the object's kinetic energy and achieving the purpose of shock absorption and energy dissipation.

[0003] However, traditional buffer components have small elastic deformation and cannot absorb the energy from impacts. Furthermore, they cannot limit movement when connected to other parts, and will produce abnormal noises when subjected to impacts or vibrations. Therefore, a newer structural design is needed that is novel, has better shock absorption and buffering effects, and has a limiting function, in order to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a buffer component to solve the problems of poor shock absorption and buffering effect and inability to limit movement during use in the above-mentioned background technology.

[0006] Preferably, the limiting part is a hemispherical structure, a cap-shaped structure that is narrow at the top and wide at the bottom, or a cylindrical structure, and the limiting part is provided with a groove for tightening the screw.

[0007] Preferably, the elastic buffer is a trapezoidal frustum shape or a cylindrical shape that is wider at the top and narrower at the bottom.

[0010] Preferably, the buffer protrusion is a hemispherical protrusion or a cylindrical protrusion.

[0011] Preferably, the elastic buffer has a through hole, and the elastic buffer is fixedly connected to the screw through the through hole.

[0012] Preferably, the through hole is provided with a reinforcing part for fastening connection, the reinforcing part and the elastic buffer are fixedly connected or integrally formed, and at least one reinforcing part is provided.

[0013] Preferably, the elastic buffer is made of silicone or rubber.

[0014] Preferably, a buffer pad for cushioning is fitted at the bottom end of the screw.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The buffer assembly of this utility model includes a screw and an elastic buffer element, with one end of the screw fixedly connected to the elastic buffer element. By setting the elastic buffer element, when an object is subjected to impact or vibration during movement, it has a certain kinetic energy. At this time, the elastic buffer element will convert this part of the kinetic energy into the elastic potential energy required for its elastic deformation, thereby reducing vibration and impact.

[0017] 2. The buffer assembly of this utility model has a limiting part at the top of the screw, which is fixedly connected to or integrally formed with the screw. By setting the limiting part, the elastic buffer can be limited while other parts are connected to the screw.

[0018] 3. The buffer assembly of this utility model has a hemispherical or cap-shaped structure that is narrower at the top and wider at the bottom as its limiting part. With this structural design, when other parts and screws are connected, their central axes and the limiting central axis can be aligned on the same central axis, effectively limiting their movement and preventing abnormal noise.

[0019] 4. The buffer assembly of this utility model has an elastic buffer element in the shape of a trapezoidal frustum, which is wider at the top and narrower at the bottom. This structural design improves the elastic deformation of the elastic buffer element, enabling it to more effectively disperse and absorb energy when subjected to impact.

[0020] 5. The buffer assembly of this utility model has buffer ribs on the elastic buffer member, with at least one buffer rib. By setting buffer ribs, the compression stroke of the elastic buffer member is effectively increased, thereby effectively improving the shock absorption and buffering effect of the elastic buffer member.

[0021] 6. The buffer assembly of this utility model has buffer protrusions on the elastic buffer member to prevent abnormal noise. The buffer protrusions and the elastic buffer member are fixedly connected or integrally formed, and at least two buffer protrusions are provided. By providing buffer protrusions, the bottom surface of the elastic buffer member and the surface of its fixing point are prevented from rubbing against each other when the screw is loose, thus avoiding abnormal noise. This improves the friction between the bottom surface of the elastic buffer member and the surface of its fixing point.

[0022] 7. The buffer assembly of this utility model has a through hole on the elastic buffer member for connecting with the screw, and a reinforcing part on the through hole for fastening the connection. The reinforcing part and the elastic buffer member are fixedly connected or integrally formed. By setting the reinforcing part, the connection between the elastic buffer member and the rod-like part is more stable, preventing the elastic buffer member from falling off.

[0023] 8. The buffer assembly of this utility model has an elastic buffer made of silicone or rubber. By selecting silicone or rubber, the elastic buffer can effectively reduce its abnormal noise while improving its absorption of shock absorption energy.

[0024] 9. The buffer assembly of this utility model has a buffer pad fitted at the bottom end of the screw for buffering. When a part moves downward on the screw, it can effectively provide shock absorption and buffering. Attached Figure Description

[0038] To further understand the utility model content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0039] like Figure 1-4 As shown, the buffer assembly includes a screw 1 and an elastic buffer 2. One end of the screw 1 is fixedly connected to the elastic buffer 2, and the top end of the screw 1 is provided with a limiting part 11 that serves a limiting function. The limiting part 11 is fixedly connected to the screw 1 or integrally formed. In this embodiment, by setting the limiting part, the elastic buffer can be limited while other parts are connected to the screw. Of course, the above structural design is not limited to this and can be other structures that serve the same function.

[0040] Specifically, the limiting part 11 is a hemispherical structure, a cap-shaped structure that is narrower at the top and wider at the bottom, or a cylindrical structure, and the limiting part 11 is provided with a groove 12 for tightening the screw 1. In this embodiment, the limiting part is a hemispherical structure or a cap-shaped structure that is narrower at the top and wider at the bottom. With the above structural setting, when other parts are connected to the screw, their central axis and the central axis of the limiting part can be aligned on the same central axis, effectively limiting the part. Of course, the above structural design is not limited to this and can be other structures or shapes that serve a limiting function.

[0041] Specifically, such as Figure 3-4 As shown, the elastic buffer 2 is a trapezoidal frustum or cylinder shape that is wider at the top and narrower at the bottom. In this embodiment, the elastic buffer is a trapezoidal frustum shape, which facilitates installation and improves the elastic deformation of the buffer, allowing it to more effectively disperse and absorb energy when subjected to impact. Of course, the above structural design is not limited to this and can be other structures or shapes that serve the same function.

[0042] Specifically, the elastic buffer 2 is provided with buffer ribs 21, and at least one buffer rib 21 is provided. In this embodiment, only one buffer rib is provided. By providing buffer ribs, the extension length can be increased, making it easier for the elastic buffer to absorb energy when subjected to impact or vibration. Of course, the above structure is not limited to this and can be other structures that perform the same function.

[0043] Specifically, such as Figure 4As shown, the elastic buffer 2 is provided with buffer protrusions 22 to prevent abnormal noise. The buffer protrusions 22 and the elastic buffer 2 are fixedly connected or integrally formed, and at least two buffer protrusions 22 are provided. In this embodiment, four buffer protrusions are provided. By providing buffer protrusions, the friction between the bottom surface of the elastic buffer and the surface of its fixing point when the screw is loose is avoided, which would cause abnormal noise, and the friction between the bottom surface of the elastic buffer and the surface of its fixing point can be improved. Of course, the number of buffer protrusions is not limited to this, and can be other numbers that serve the same purpose.

[0044] Specifically, the buffer protrusion 22 is a hemispherical or cylindrical protrusion. In this embodiment, the buffer protrusion is hemispherical, which effectively prevents abnormal noise. Of course, the shape of the buffer protrusion is not limited to this; it can be other structures or shapes that prevent abnormal noise.

[0045] Specifically, the elastic buffer 2 has a through hole 23, through which it is fixedly connected to the screw. The through hole 23 has a reinforcing part 24 for fastening the connection. The reinforcing part 24 is fixedly connected to or integrally formed with the elastic buffer 2, and at least one reinforcing part 24 is provided. In this embodiment, three reinforcing parts are provided. By providing reinforcing parts, the connection between the elastic buffer and the screw is more stable, preventing the elastic buffer from falling off. Of course, the above structural design is not limited to this; other structures that prevent falling off can also be used.

[0046] Specifically, the elastic buffer 2 is made of silicone or rubber. In this embodiment, by selecting the material, the energy absorbed by the elastic buffer is improved while effectively reducing its abnormal noise. Of course, the material of the elastic buffer is not limited to this; it can also be other materials that perform shock absorption and cushioning.

[0047] Specifically, a buffer pad 3 is fitted at the bottom end of the screw 1 to provide cushioning. In this embodiment, by providing the buffer pad, when a part moves downward on the screw, it can effectively provide shock absorption and cushioning. Of course, the above structural design is not limited to this; it can be other structures or shapes that provide shock absorption and cushioning.

[0048] Example 2

[0049] The basic structural settings of Embodiment 1 and Embodiment 2 are the same, the main difference is:

[0050] Specifically, the limiting part 11 is a hemispherical structure, a cap-shaped structure that is narrower at the top and wider at the bottom, or a cylindrical structure, and the limiting part 11 is provided with a groove for tightening the screw 1. In this embodiment, the limiting part is a cylindrical structure. With the above-mentioned structural setting, when other parts are connected to the screw, their central axis and the central axis of the limiting part can be aligned on the same central axis, effectively limiting the connection. Of course, the above structural design is not limited to this and can be other structures or shapes that serve a limiting function.

[0051] Specifically, the elastic buffer 2 is a trapezoidal frustum or cylinder shape that is wider at the top and narrower at the bottom. In this embodiment, the elastic buffer is cylindrical. This structural design facilitates installation while improving the elastic deformation of the buffer, allowing it to more effectively disperse and absorb energy when subjected to impact. Of course, the above structural design is not limited to this; it can be other structures or shapes that serve the same function.

[0052] Specifically, the elastic buffer 2 is provided with buffer ribs 21, and at least one buffer rib 21 is provided. In this embodiment, one to eight buffer ribs are provided, evenly distributed on the elastic buffer. By providing buffer ribs, the elongation can be increased, making it easier for the elastic buffer to absorb energy when subjected to impact or vibration. Of course, the number of buffer ribs is not limited to this, and can be any number that serves to increase the elongation.

[0053] Specifically, the elastic buffer 2 is provided with buffer protrusions 22 for preventing abnormal noise. The buffer protrusions 22 are fixedly connected to or integrally formed with the elastic buffer 2, and at least two buffer protrusions 22 are provided. In this embodiment, two to eight buffer protrusions are provided, evenly arranged in a circumferential array around the elastic buffer. This can prevent abnormal noise caused by the bottom surface of the elastic buffer and its fixing surface rubbing against each other when the screw is loose, and can improve the friction between the bottom surface of the elastic buffer and its fixing surface. Of course, the number of buffer protrusions is not limited to this, and can be other numbers that serve to prevent abnormal noise.

[0054] Specifically, the through hole 23 is provided with a reinforcing part 24 for fastening connection. The reinforcing part 24 and the elastic buffer 2 are fixedly connected or integrally formed, and at least one reinforcing part 24 is provided. In this embodiment, two to eight reinforcing parts are provided, evenly arranged in a circumferential array around the through hole. By providing reinforcing parts, the connection between the elastic buffer and the screw is made more stable, preventing the elastic buffer from falling off. Of course, the number of reinforcing parts is not limited to this, and can be other numbers that serve a fastening connection function.

[0055] Working principle: It includes a screw and an elastic buffer, with one end of the screw fixedly connected to the elastic buffer. When a component moves on the screw, the stiffness and shape of the elastic buffer affect the torque attenuation effect when subjected to impact or vibration. Torque attenuation refers to the spring buffer absorbing part of the torque and converting it into elastic deformation energy, thereby reducing vibration and impact. The structure of the limiting part, wider at the top and narrower at the bottom, ensures that when other parts are connected to the screw, their central axis and the limiting part's central axis are aligned, effectively limiting their movement. The elastic buffer is a trapezoidal frustum shape, wider at the top and narrower at the bottom. This structural design improves the elastic deformation of the buffer, allowing it to more effectively disperse and absorb energy when impacted. The buffer is further enhanced by the inclusion of buffer ribs. This design effectively increases the compression stroke of the elastic buffer, thereby improving its shock absorption and cushioning effect. By incorporating buffer protrusions, it prevents the bottom surface of the elastic buffer from rubbing against its fixing surface when the screw loosens, thus reducing noise and increasing friction between the bottom surface of the elastic buffer and its fixing surface. The elastic buffer has through holes for connection with the screw, and reinforcing parts for fastening the connection are fixedly connected to or integrally formed with the elastic buffer. The reinforcing parts ensure a more stable connection with rod-like parts, preventing the elastic buffer from falling off. The inclusion of buffer pads effectively provides shock absorption and cushioning when parts move downwards on the screw.

[0056] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
