[0071] As described in the background, most of the present stage of the scooter does not have a damping structure, and the riding experience is poor when the scooter encounters a bumpy road. In addition, some models with damping structure are mainly achieved by spring damping, which generally has two obvious problems: one is that the spring damping is usually arranged on both sides of the front fork, which makes the overall appearance of the scooter insufficient; the second is that the spring damping has a large abnormal sound when passing through the bumpy road due to the characteristics of the spring itself, which affects the riding experience.

[0072] In view of the above technical problems, the front fork structure with damping characteristics and the vehicle provided by the embodiments of the present application are provided. The front fork structure includes a main body part, a bending part and two damping devices. The bending part is connected with the main body part. The bending part has an opening, the opening direction is away from the main body part, and the bending part has a U-shaped structure and a double-layer structure. The two damping devices are respectively connected with the two ends of the bending part away from the main body part. The vehicle includes a wheel body and the above-mentioned front fork structure. One end of the damping device of the front fork structure is connected with the bending part of the front fork structure, and the other end of the damping device of the front fork structure is connected with the wheel body. In this way, the present application can achieve damping by setting the elastic element, so that the vehicle does not produce noise when it is in the working state, and the characteristics of the elastic element make the damping device work more linearly, and the damping rebound is also more soft, and the experience is good. In addition, on the basis of connecting the damping device with the front fork structure, the vehicle has a large drag distance, and the riding stability is improved.

[0073] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0074] The embodiments of the present application provide a front fork structure with damping characteristics and a vehicle, which achieves damping by setting an elastic element, so that the vehicle does not produce noise when it is in the working state, and the characteristics of the elastic element make the damping device work more linearly, and the damping rebound is also more soft, and the experience is good. In addition, on the basis of connecting the damping device with the front fork structure, the vehicle has a large drag distance, and the riding stability is improved. The specific structure of the front fork structure with damping characteristics and the vehicle provided by the embodiments of the present application will be introduced below with reference to the drawings.

[0075] Reference Figure 1In a first aspect, the embodiment of the present application provides a front fork structure 200 with shock absorption characteristics, which can include a main body part 210, a bending part 220 and a shock absorption device 100. In combination Figure 6 In a possible implementation, the number of shock absorption devices 100 can be at least two, and the present application does not limit the number of shock absorption devices 100. In the embodiment of the present application, the number of shock absorption devices 100 is taken as an example of two. In a possible implementation, the shape of the main body part 210 can be a cylindrical structure, and the present application does not limit the shape of the main body part 210. In the embodiment of the present application, the bending part 220 can have an opening 221, and the opening 221 of the bending part 220 can be arranged to face away from the main body part 210. It can be understood that the main body part 210 can be connected to the bending part 220 to form the front fork structure 200. In this way, two shock absorption devices 100 can be connected to the two ends of the bending part 220 away from the main body part 210, thereby achieving good shock absorption function of the front fork structure 200.

[0076] With reference to the above embodiment, Figure 1 On the basis of the above embodiment, the bending part 220 can have a U shape, and the bending part 220 can also have a double-layer structure. In a possible implementation, the bending part 220 can be a square tube structure, which is flattened in the embodiment of the present application to form a flat structure, and then is bent to form a U shape, and finally is welded or connected in other ways to form the bending part 220. In this way, after the square tube structure is flattened, the square tube structure with a hollow cavity is flattened to form a flat bending part 220 with a double-layer structure. Compared with the front fork structure 200 in the related art, the front fork structure 200 provided by the embodiment of the present application enhances the stiffness performance of the structure itself.

[0077] With reference to the above embodiment, Figure 2On the basis of the above-mentioned embodiments, each damping device 100 can include a shell 110, an elastic member 120, and a rotating shaft 130. In one possible implementation, the shape of the elastic member 120 can be a cylindrical structure, which is not limited in the present application. In the present embodiment, the shell 110 can have a hollow first cavity 111 in a cylindrical shape inside, so that the elastic member 120 can be located in the first cavity 111 of the shell 110. In one possible implementation, the elastic member 120 can be inserted into the first cavity 111 of the shell 110, and because the elastic member 120 has a certain torsional characteristic, the elastic member 120 can be used to reduce the vibration of the first external connecting member. In addition, one end of the rotating shaft 130 can be connected to the elastic member 120, and the other end of the rotating shaft 130 can be connected to the bending portion 220. In one possible implementation, the end of the rotating shaft 130 towards the elastic member 120 can be provided with a stepped structure, so that the rotating shaft 130 can be connected to the elastic member 120 through the stepped structure.

[0078] It should be noted that in one possible implementation, the first external connecting member can be a wheel body 310.

[0079] On the basis of the above-mentioned embodiments, the elastic member 120 can be made of rubber material. It can be understood that rubber has high elasticity, small elastic modulus, and still has a recoverable characteristic after being subjected to external force. In addition, rubber also has the effect of buffering and damping, and has a certain moderating effect on the propagation of sound and vibration.

[0080] Continuing to refer to Figure 2 On the basis of the above-mentioned embodiments, further, the damping device 100 can also include a first fixing member 140. In one possible implementation, the first fixing member 140 can be a bushing, and the shape of the first fixing member 140 can also be a cylindrical structure, which is not limited in the present application. In the present embodiment, the first fixing member 140 can have a hollow second cavity 141 inside, so that the first fixing member 140 can be sleeved on the elastic member 120, that is, the elastic member 120 is first inserted into the second cavity 141 of the first fixing member 140, and then the elastic member 120 and the first fixing member 140 are integrally inserted into the first cavity 111 of the shell 110. In one possible implementation, the first fixing member 140, the elastic member 120, and the rotating shaft 130 can be formed into an integral whole through a vulcanization process, and then be press-fitted into the inside of the shell 110. It can be understood that through the vulcanization process, the elastic member 120 made of rubber material can be cross-linked into a spatial network structure, having good use performance.

[0081] Referring to Figure 2and Figure 3 On the basis of the above-mentioned embodiments, in one possible implementation, after the first fixing member 140, the elastic member 120 and the rotating shaft 130 are pressed into the inside of the shell 110, the first fixing member 140 and the elastic member 120 can be arranged flush with the inner side wall of the shell 110, that is, the first fixing member 140 and the elastic member 120 are both completely located in the first cavity 111 of the shell 110, at least part of the rotating shaft 130 is located in the first cavity 111 of the shell 110, and another part of the rotating shaft 130 protrudes out of the shell 110, so that the rotating shaft 130 is connected with the second external connecting member.

[0082] With reference to the above-mentioned embodiments, Figure 2 and Figure 3 On the basis of the above-mentioned embodiments, one end of the shell 110 can have an extension 112. The first recess 113 can be formed on the extension 112. In this way, the first external connecting member can be arranged in the first recess 113, so that the shell 110 can be connected with the first external connecting member through the first recess 113.

[0083] With reference to the above-mentioned embodiments, Figure 1 On the basis of the above-mentioned embodiments, further, the front fork structure 200 can further include a second fixing member 230. The second fixing member 230 can be located between the main body part 210 and the bent part 220. In one possible implementation, the second fixing member 230 can also be a bushing, and the shape of the second fixing member 230 can also be a cylindrical structure, and the shape of the second fixing member 230 is not limited herein. In the embodiments of the present application, the inside of the second fixing member 230 can have a hollow third cavity 231, so that one end of the second fixing member 230 can be sleeved on the main body part 210, that is, the main body part 210 can be inserted into the third cavity 231 of the second fixing member 230. Correspondingly, the other end of the second fixing member 230 can be connected with the bent part 220, so that the main body part 210 and the bent part 220 are fixedly connected through the second fixing member 230.

[0084] With reference to the above-mentioned embodiments, Figure 4 On the basis of the above-mentioned embodiments, the front fork structure 200 further includes a front fork hook claw 240. In one possible implementation, the number of the front fork hook claws 240 can be at least two, and the number of the front fork hook claws 240 is not limited herein. In the embodiments of the present application, the number of the front fork hook claws 240 is taken as two for example. The two front fork hook claws 240 can be respectively located at two ends of the bent part 220, and each front fork hook claw 240 can be fixedly connected with the bent part 220.

[0085] With reference to the above-mentioned embodiments, Figure 4On the basis of the above-mentioned embodiments, a second groove 241 can be formed on each front fork hook claw 240. Among them, two second grooves 241 can be oppositely arranged. In this way, the shock-absorbing device 100 can be arranged in the second groove 241, so that the front fork hook claw 240 can be connected with the shock-absorbing device 100 through the second groove 241. Further, the rotating shaft 130 in the shock-absorbing device 100 can be arranged in the second groove 241, so that the rotating shaft 130 in the shock-absorbing device 100 is connected with the front fork hook claw 240 in the front fork structure 200, and then the shock-absorbing device 100 is connected with the front fork structure 200.

[0086] In a possible implementation, refer to the accompanying drawings Figure 7 to the accompanying drawings Figure 12 The bending part 220 is arranged obliquely relative to the running direction of the vehicle, and the end of the bending part 220 connected with the shock-absorbing device 100 is located at the rear side of the end of the main body part 210. Figure 7 The running direction of the vehicle is the M direction in the accompanying drawings.

[0087] It should be noted that the extension direction of the main body part 210 in the embodiment can be perpendicular to the running direction of the vehicle, or can be arranged obliquely relative to the running direction of the vehicle, and the oblique direction is the same as the oblique direction of the bending part 220.

[0088] When the wheel body 310 of the vehicle encounters an obstacle, the impact force can be transmitted along the bending part 220, which helps to more effectively absorb and disperse the impact force, reduce the impact directly acting on the main body structure of the vehicle, and thus enhance the stability and safety of the vehicle. In addition, the end of the bending part 220 connected with the shock-absorbing device 100 is located at the rear side of the end of the main body part 210, and when the impact occurs, the energy is absorbed and relieved by the deformation of the bending part 220, further cooperating with the working of the shock-absorbing device 100, improving the overall shock-absorbing effect, and thus helping to protect the vehicle and its passengers from the influence of violent vibration, and improving the riding comfort.

[0089] In the embodiment, the bending part 220 can be made of a flat round pipe, and the number of the bending part 220 is two. The two bending parts 220 are connected with the main body part 210 through the second fixing part 230, and the two bending parts 220 enclose the opening 221 accommodating the wheel body 310. Among them, the two bending parts 220 are symmetrically arranged relative to the main body part 210. The design of the flat round pipe makes the bending part 220 controllably deform when subjected to the impact force, thereby absorbing and dispersing the energy. In addition, the two bending parts are symmetrically arranged, and they can jointly bear the impact force, further improving the energy absorption efficiency.

[0090] Refer to the accompanying drawings Figure 10 and the accompanying drawings Figure 11In a possible implementation, the bending part 220 includes a first bending part 222 and a second bending part 223; the first bending part 222 is connected with the main body part 210; in other words, the first bending part 222 is connected with the second fixing part 230.

[0091] The second bending part 223 is connected with the first bending part 222, and an end of the second bending part 223, which is away from the first bending part 222, extends in a direction away from the wheel shaft of the vehicle; in other words, the second bending part 223 extends in a direction away from the wheel shaft of the wheel body 310. In this way, the spatial layout of the components is optimized. By reasonably adjusting the length and angle of the first bending part 222 and the second bending part 223, the limited space resource can be effectively utilized, and interference or conflict with other components can be avoided, thereby improving the compactness and integration of the entire vehicle.

[0092] In order to facilitate the connection between the bending part 220 and the rotating shaft 130, the second bending part 223 is provided with a fixing hole 224, the rotating shaft 130 is arranged in the fixing hole 224, and the rotating shaft 130 and the second bending part 223 are connected together through a nut.

[0093] In the embodiment, the bending part 220 further includes a flat part 225, and the thickness of the flat part 225 is smaller than the thickness of the rest of the second bending part 223. In other words, the part of the second bending part 223, which is away from the first bending part 222, can be molded to form the flat part 225.

[0094] The fixing hole 224 is arranged in the flat part 225. When the rotating shaft 130 is installed in the fixing hole 224, the contact area of the flat part 225 with the shell 110 or the elastic part 120 is increased, thereby improving the connection strength between the damping device 100 and the bending part 220.

[0095] It should be noted that the connection between the front fork structure 200 and the wheel body 310 is mainly based on the connection of the shell 110 of the damping device 100. In order to further improve the connection stability of the front fork structure 200 and the wheel body 310.

[0096] Please refer to the accompanying drawings Figure 9 The vehicle provided in the embodiment further includes a connecting part 400, one end of the connecting part 400 is sleeved on the rotating shaft 130, and the other end of the connecting part 400 is sleeved on the wheel shaft 320. In this way, the torsion of the wheel body 310 during rotation can be reduced through the connecting part 400, thereby improving the overall rigidity of the vehicle, so that the wheel body 310 can maintain a more stable posture during driving, the vibration and noise caused by the torsion are reduced, and the driving comfort and stability are improved.

[0097] Please refer to the accompanying drawings Figure 12In a possible implementation, the shell 110 is further provided with a connecting protrusion 114, which is rotationally connected to the connecting member 400 through a connecting shaft. Alternatively, the connecting protrusion 114 has a connecting hole, and the connecting shaft provided on the connecting member 400 is arranged in the connecting hole, so that the shell 110 can be rotationally connected to the connecting member 400. In this way, during the driving of the vehicle, especially on uneven road surfaces, the wheel body 310 may encounter various obstacles and bumps, which may cause the wheel shaft 320 to be subjected to forces and torques in different directions. By allowing the shell 110 to be twisted relative to the wheel shaft 320, this design can better absorb and disperse these forces and torques, thereby reducing the bumping of the vehicle.

[0098] Please refer to the accompanying drawings Figure 9 Further, the vehicle further includes an annular guide member 500 connected to the connecting member 400 and sleeved on the connecting protrusion 114, wherein the annular guide member 500 is provided with a guide groove 510; and the shell 110 further includes a guide protrusion 115 slidingly arranged in the guide groove 510. In this way, the guide groove 510 not only guides the shock-absorbing device 100, but also limits the shock-absorbing device 100.

[0099] Please refer to the accompanying drawings Figure 8 In a possible implementation, the vehicle further includes a wire harness fixing member 600; and the wire harness fixing member 600 is arranged on the front fork structure 200. The wire harness fixing member 600 provides a fixing point for the wire harness such as electric wires and cables in the vehicle. By fixing these wire harnesses neatly on the wire harness fixing member, the wire harnesses can be prevented from swinging or entangling with each other in the vehicle, thereby improving the efficiency and neatness of wire harness management.

[0100] The wire harness fixing member 600 surrounds at least part of the outer circumferential surface of the bent portion 220; and the wire harness fixing member 600 is provided with a U-shaped fixing groove 610. The U-shaped fixing groove 610 facilitates the fixing of the wire harness, thereby improving the stability of the wire harness.

[0101] Reference Figure 5 The second aspect of the embodiments of the present application provides a vehicle 300. In the embodiments of the present application, the vehicle 300 can be a scooter, a bicycle, an electric vehicle or the like. The vehicle 300 can include a wheel body 310 and the above-mentioned front fork structure 200. In the front fork structure 200, one end of each shock-absorbing device 100 can be connected to the bent portion 220 of the front fork structure 200, and the other end of each shock-absorbing device 100 can be connected to the wheel body 310. In this way, the wheel body 310 does not directly contact the front fork structure 200, and when the wheel body 310 is subjected to an impact, the shock-absorbing device 100 can absorb the impact force of the wheel body 310, thereby achieving a shock-absorbing effect.

[0102] Reference Figure 5 And Figure 6 On the basis of the above embodiment, the vehicle 300 can further comprise: an axle 320. It can be understood that the axle 320 can be disposed through the wheel body 310. In a possible implementation, the axle 320 can be located at the center of the wheel body 310, and the axle 320 can be protrudingly disposed on both sides of the wheel body 310, so that both ends of the axle 320 are protrudingly disposed on the wheel body 310. In this way, both ends of the axle 320 can be disposed through the first groove 113 of each shell 110, so that the shell 110 is connected with the wheel body 310. In a possible implementation, the axle 320 is disposed through the first groove 113, and then fixedly connected by a bolt, so that the shell 110 is fixedly connected with the wheel body 310.

[0103] With reference to the above Figure 5 On the basis of the above embodiment, the axle 320 can be matched with the first groove 113, so that the axle 320 and the shell 110 cannot rotate relative to each other. In a possible implementation, the axle 320 protrudingly disposed on both ends of the wheel body 310 can be a rectangular structure, and correspondingly, the first groove 113 formed on the shell 110 can also be a rectangular structure, so that the axle 320 is matched with the first groove 113, and the axle 320 and the shell 110 can be hard connected and cannot rotate relative to each other. In this way, since the position of the axle 320 and the shell 110 is fixed, when the wheel body 310 is impacted, the elastic member 120 in the shell 110 can be twisted, so as to absorb the impact force of the wheel body 310 and achieve the damping effect.

[0104] With reference to the above Figure 5 On the basis of the above embodiment, in combination with Figure 4 It can be seen that the shaft 130 can be matched with the second groove 241, so that the shaft 130 and the fork structure 200 cannot rotate relative to each other. In a possible implementation, the shaft 130 protrudingly disposed on one end of the shell 110 can be a rectangular structure, and correspondingly, the second groove 241 formed on the fork hook 240 can also be a rectangular structure, so that the shaft 130 is matched with the second groove 241, and the shaft 130 and the fork structure 200 can be hard connected and cannot rotate relative to each other. In this way, when the wheel body 310 is impacted, the wheel body 310 can rotate around the shaft 130, and since the position of the shaft 130 and the fork structure 200 is fixed, and the position of the shell 110 and the axle 320 is also fixed. At this time, the elastic member 120 in the shell 110 can be twisted, so as to further absorb the impact force of the wheel body 310 and achieve the damping effect.

[0105] With reference to the above Figure 5On the basis of the above-mentioned embodiments, in a possible implementation, it can be understood that L1 can be a bottom surface horizontal line, L2 can be a center line of the front fork structure 200, and L3 can be a center line of the wheel body 310 perpendicular to the bottom surface. In addition, M can be the intersection of L1 and L2, and N can be the intersection of L1 and L3. The distance between M and N points can be the trail of the vehicle 300 provided in the present application. It can be understood that when the trail of the vehicle 300 is larger, the pointing performance of the vehicle 300 is also better. The vehicle 300 can more easily maintain straight driving, and will not easily change direction because of small obstacles on the road. Therefore, the trail of the vehicle 300 provided in the present application can improve the stability of the vehicle 300 riding.

[0106] In the embodiments of the present application, the elastic member 120 is arranged to achieve shock absorption, so that the vehicle 300 does not produce noise when in the working state, and the characteristics of the elastic member 120 make the shock absorption device 100 more linear when working, and the shock absorption rebound is also more soft, and the experience is good. In addition, on the basis that the shock absorption device 100 is connected with the front fork structure 200, the vehicle 300 has a larger trail, and the riding stability is improved.
