[0039] To make the technical solution and beneficial effects of this application more apparent and understandable, a detailed description is provided below by listing specific embodiments. The accompanying drawings are not necessarily drawn to scale, and local features may be enlarged or reduced to more clearly show the details of the local features; unless otherwise defined, the technical and scientific terms used herein have the same meanings as those in the technical field to which this application pertains.

[0040] Researchers have discovered that some traditional scooter steering assist return mechanisms include a first connection structure fixedly connected to the rotating components of the frame, and a second connection structure fixedly connected to the main body of the frame. The first connection structure has a return annular groove. A fixing component and a slider are located within the return annular groove. Elastic components are located on both sides of the slider. One end of each elastic component presses against the slider, and the other end presses against the fixing component. The elastic components on both sides of the slider are spaced apart along the circumference of the return annular groove. To ensure consistent return-to-center performance on both sides, the two elastic components are generally the same size. Therefore, the central angle of each elastic component is less than 180°. When the slider moves circumferentially along the return annular groove, the compression ratio of the elastic components is often large, resulting in significant deformation. Repeated deformation with large compression ratios can easily lead to elastic failure of the elastic components, reducing their service life.

[0041] Based on this, researchers proposed a steering assist return-to-center mechanism. When the slider is in the return-to-center state, the two ends of the elastic element abut against the two ends of the fixed element along the circumferential direction of the return-to-center groove, and the central angle corresponding to the elastic element is relatively large. When the slider moves along the circumferential direction of the return-to-center groove, the compression ratio of the elastic element is reduced, the degree of deformation of the elastic element is reduced, the risk of elastic failure of the elastic element is reduced, and the service life of the elastic element is increased.

[0042] In this application, when the slider is in the return-to-center state, a fixed member and an elastic member are sequentially abutted along the circumference of the return-to-center groove. The fixed member and the elastic member do not overlap in the circumference of the return-to-center groove. Therefore, the sum of the central angles corresponding to the fixed member and the elastic member is 360°. If the central angle corresponding to the fixed member in this application remains unchanged compared to the fixed member in a conventional steering assist return-to-center mechanism, then the central angle corresponding to the elastic member in this application is equal to the sum of the central angles corresponding to the two elastic members and the slider in a conventional steering assist return-to-center mechanism. The central angle corresponding to the elastic member in this application is greater than the sum of the central angles corresponding to the two elastic members in a conventional steering assist return-to-center mechanism.

[0043] To facilitate understanding, specific examples are provided below.

[0044] In a traditional scooter, when the slider is in the centered position, it is assumed that the central angles of the elastic elements on both sides of the slider are 150°. When the slider moves 30° to one side around the centered groove, the central angle of the elastic element on that side decreases to 120°, and the compression ratio of the elastic element is 0.2.

[0045] In the steering assist return mechanism provided in this application, when the slider is in the return state, the central angle of the elastic element is at least equal to the sum of the central angles of the two elastic elements in the steering assist return mechanism of a conventional scooter. Assuming the central angle of the elastic element is 330° when the slider is in the return state, when the slider moves 30° to one side around the return groove, the corresponding central angle of the elastic element decreases to 300°, and the compression ratio of the elastic element is less than 0.1. Clearly, in this application, when the slider moves the same angle to one side around the return groove, the compression ratio of the elastic element is significantly reduced.

[0046] See Figures 1 to 7This application provides a steering assist return mechanism 100 for a vehicle frame. The vehicle frame includes a main body and a rotating assembly rotatably connected to the main body. The steering assist return mechanism 100 includes a first connecting structure 110 and a return drive assembly 130. The first connecting structure 110 is fixedly connected to the rotating assembly. The first connecting structure 110 has a return annular groove 111. A fixing member 112 is fixedly provided on the inner wall 1111 of the return annular groove 111. Along the circumference of the return annular groove 111, the two ends of the fixing member 112 have a first stop 1121 and a second stop 1122, respectively. The return drive assembly 130 includes an elastic member 131 and a slider 132. The elastic member 131 is disposed in the return annular groove 111. Along the circumference of the return annular groove 111, the elastic member 131 has a first end 1311 and a second end 1312 facing away from each other. The slider 132 is disposed within the return annular groove 111 and located between the first end 1311 and the second end 1312 of the elastic member 131. The slider 132 is used for fixed connection with the main body. The slider 132 can slide along the return annular groove 111 to switch between a return state and a deviated state. When the slider 132 is in the return state, the first end 1311 and the second end 1312 of the elastic member 131 abut against the first stop 1121 and the second stop 1122, respectively. When the slider 132 is in the return state, it can move circumferentially along the return annular groove 111 and push the first end 1311 of the elastic member 131 to move, thereby switching to the deviated state. When the slider 132 is in the return state, it can also move circumferentially along the return annular groove 111 and push the second end 1312 of the elastic member 131 to move, thereby switching to the deviated state.

[0047] Understandably, when the steering assist return mechanism 100 is applied to the scooter frame, the scooter is also in the return state when the slider 132 is in the return state. When the slider 132 is in the deviated state, the rotating component in the scooter frame also rotates relative to the main body to the deviated state.

[0048] Understandably, during the riding of a scooter, there are operations such as turning left from the centered position and turning right from the centered position. Similarly, when the slider 132 is in the centered position, it can move to one side along the centered ring groove 111, and it can also move to the other side along the centered ring groove 111.

[0049] Furthermore, it is understandable that once slider 132 deviates from the alignment state, it is in the deviated state. In other words, the deviated state of slider 132 is not limited to one or a few specific positions.

[0050] Furthermore, it is understandable that when one end 1311 and the other end 1312 of the elastic member 131 are moved by the slider 132, the other end still abuts against the stop of the corresponding end of the fixing member 112.

[0051] It should be noted that, in this application, the inner wall 1111 of the return ring groove 111 refers to the inner surface of the groove wall of the return ring groove 111 that is exposed inside the return ring groove 111.

[0052] In the aforementioned steering assist return mechanism 100, when the slider 132 is in the return state, both ends of the elastic element 131 abut against both ends of the fixed element 112, and the central angle corresponding to the elastic element 131 is relatively large. As the slider 132 moves circumferentially along the return annular groove 111, the compression ratio of the elastic element 131 when compressed is reduced, the degree of deformation of the elastic element 131 is reduced, the risk of elastic failure of the elastic element 131 is reduced, and the service life of the elastic element 131 is increased.

[0053] Furthermore, increasing the service life of the elastic element 131 can also reduce the frequency of maintenance and replacement of the elastic element 131, thereby reducing maintenance costs.

[0054] In addition, the number of elastic elements 131 is reduced, which reduces the assembly steps of the steering assist return mechanism 100 and improves the assembly efficiency of the steering assist return mechanism 100.

[0055] Furthermore, it is understandable that when the slider 132 is in the return state, along the circumferential direction of the return annular groove 111, the slider 132 partially overlaps with the first stop 1121 and the second stop 1122 of the fixing member 112; along the radial direction of the return annular groove 111, the slider 132 is offset from the fixing member 112.

[0056] In this embodiment, the return-to-center drive assembly 130 further includes a first adapter 133. The first stop 1121 and the first end 1311 of the elastic member 131 abut against each other via the first adapter 133. The slider 132 pushes the first end 1311 of the elastic member 131 to move via the first adapter 133. It can be understood that regardless of whether the slider 132 is in the return-to-center state or the deviated state, the first end 1311 of the elastic member 131 remains in contact with the first adapter 133. This ensures that the element directly contacting the first end 1311 of the elastic member 131 remains unchanged, making the pressure on different positions of the elastic member 131 more balanced, and making the compression and elongation of the elastic member 131 more stable.

[0057] In this embodiment, the return-to-center drive assembly 130 further includes a second adapter 134. The second stop 1122 and the second end 1312 of the elastic member 131 abut against each other via the second adapter 134. The slider 132 pushes the second end 1312 of the elastic member 131 to move via the second adapter 134. It can be understood that regardless of whether the slider 132 is in the return-to-center state or the deviated state, the second end 1312 of the elastic member 131 remains in contact with the second adapter 134. This ensures that the element directly contacting the second end 1312 of the elastic member 131 remains unchanged, making the pressure on different positions of the elastic member 131 more balanced, and making the compression and elongation of the elastic member 131 more stable.

[0058] In this embodiment, the first end 1311 of the elastic member 131 is elastically interference-fitted with the first adapter 133. Through the elasticity of the elastic member 131, the first end 1311 of the elastic member 131 and the first adapter 133 are abutted together. The connection method is simple and easy to assemble.

[0059] In this embodiment, the second end 1312 of the elastic member 131 is elastically interference-fitted with the second adapter 134. Through the elasticity of the elastic member 131, the second end 1312 of the elastic member 131 and the second adapter 134 are abutted together. The connection method is simple and easy to assemble.

[0060] Furthermore, the first end 1311 of the elastic element 131 is elastically interference-fitted with the first adapter 133. The second end 1312 of the elastic element 131 is elastically interference-fitted with the second adapter 134. Therefore, when the slider 132 is in the centered state, the elastic element 131 is in a compressed state. After the slider 132 switches from the centered state to the deflected state, the elastic element 131 is further compressed. Thus, the elastic element 131 is always in a compressed state.

[0061] In this embodiment, the first adapter 133 is clearance-fitted with both the inner sidewall 1112 and the outer sidewall 1113 of the return annular groove 111, so that when the first adapter 133 moves circumferentially along the return annular groove 111, the first adapter 133 is prevented from tilting radially relative to the return annular groove 111, making the elastic compression and elongation more stable.

[0062] It should be noted that, in this application, both the inner wall 1112 and the outer wall 1113 of the return annular groove 111 are part of the interior of the return annular groove 111. Specifically, the inner wall 1112 of the return annular groove 111 refers to the inner surface of the side wall of the return annular groove 111 closest to the axis along the radial direction of the return annular groove 111. The outer wall 1113 of the return annular groove 111 refers to the inner surface of the side wall of the return annular groove 111 furthest from the axis along the radial direction of the return annular groove 111.

[0063] It is understandable that the inner wall 1112 and the outer wall 1113 of the return annular groove 111 are both annular.

[0064] Specifically, in this embodiment, the first adapter 133 is plate-shaped, with a simple structure that is easy to process.

[0065] In this embodiment, the second adapter 134 is clearance-fitted with both the inner sidewall 1112 and the outer sidewall 1113 of the return annular groove 111, so that when the second adapter 134 moves circumferentially along the return annular groove 111, the second adapter 134 is prevented from tilting radially relative to the return annular groove 111, making the elastic compression and elongation more stable.

[0066] Specifically, in this embodiment, the second adapter 134 is plate-shaped, with a simple structure that is easy to process.

[0067] In this embodiment, there are two fixing members 112, namely a first fixing member 112a and a second fixing member 112b. The first fixing member 112a and the second fixing member 112b are arranged radially at intervals along the return annular groove 111. The first fixing member 112a is provided on the inner sidewall 1112 of the return annular groove 111. The second fixing member 112b is provided on the outer sidewall 1113 of the return annular groove 111. The first stop portion 1121 of the first fixing member 112a is coplanar with the first stop portion 1121 of the second fixing member 112b.

[0068] The first stop portion 1121 of the first fixing member 112a and the first stop portion 1121 of the second fixing member 112b are coplanar, such that both radially opposite sides of the first end 1311 of the elastic member 131 abut against the fixing member 112, resulting in a more uniform radial distribution of the force on the first end 1311 of the elastic member 131 and reducing the risk of local stress concentration. Similarly, the first stop portion 1121 of the first fixing member 112a and the first stop portion 1121 of the second fixing member 112b are coplanar, such that both radially opposite sides of the second end 1312 of the elastic member 131 are abut against the fixing member 112, resulting in a more uniform radial distribution of the force on the second end 1312 of the elastic member 131 and reducing the risk of local stress concentration.

[0069] In this embodiment, the first stop 1121 is planar. It is understood that in other embodiments, the first stop 1121 is not limited to this, and may also be a curved surface, a folded surface, or other regular or irregular surface, or may be linear or multi-point.

[0070] In this embodiment, the second stop 1122 is planar. It is understood that in other embodiments, the second stop 1122 is not limited to this, and may also be a curved surface, a folded surface, or other regular or irregular surface, or may be pre-installed or multi-point.

[0071] Understandably, in this embodiment, when the slider 132 is in the centered state, it is located between the first fixing member 112a and the second fixing member 112b along the radial direction of the centered annular groove 111. When the slider 132 moves to the deviated state along the circumferential direction of the centered annular groove 111, the slider 132 does not contact the inner wall 1112 and the outer wall 1113 of the centered annular groove 111, reducing the friction between the slider 132 and the inner wall 111 of the centered annular groove 111 during the movement.

[0072] It is understood that in some embodiments, the number of fasteners is not limited to two, but may be one or more. For example, in some embodiments, the number of fasteners is one, which is fixed to the inner or outer sidewall of the return annular groove. Furthermore, in some embodiments, the number of fasteners is more than two, and the multiple fasteners include a first fastener and a second fastener. In this case, at least one of the first fastener and the second fastener is two.

[0073] In this embodiment, the fastener 112 and the first connecting structure 110 are integrally formed, reducing assembly steps and improving assembly efficiency. It is understood that in other embodiments, the fastener and the first connecting structure can be manufactured separately and then fixedly connected by welding, bonding, or threaded connections.

[0074] In this embodiment, the bottom wall 1114 of the return annular groove 111 is provided with a limiting groove 1115, which extends circumferentially along the return annular groove 111. The bottom side of the slider 132 is provided with a limiting insert 1321 that matches the limiting groove 1115. The limiting groove 1115 and the limiting insert 1321 cooperate to limit the radial movement of the limiting insert 1321 within the return annular groove 111, thereby limiting the radial movement of the slider 132 within the return annular groove 111, allowing the slider 132 to move more stably along the circumferential direction of the return annular groove.

[0075] It should be noted that, in this embodiment, the bottom wall 1114 of the return annular groove 111 is a part of the inner wall 1111 of the return annular groove 111. Specifically, the bottom wall 1114 of the return annular groove 111 refers to the inner surface of the bottom side wall of the return annular groove 111.

[0076] In this embodiment, the elastic element 131 is a spring. It is understood that in other embodiments, the elastic element may be other elastic structures.

[0077] join Figure 8In another embodiment of the steering assist return mechanism provided in this application, the fixing member 112 includes a first sub-fixing member 1123 and a second sub-fixing member 1124. A first stop 1121 is provided on the first sub-fixing member 1123. A second stop 1122 is provided on the second sub-fixing member 1124.

[0078] Specifically, in this embodiment, the first sub-fixing member 1123 is disposed on the inner sidewall 1112 of the return annular groove 111, and the second sub-fixing member 1124 is disposed on the outer sidewall 1113 of the return annular groove 111. It is understood that in some other embodiments, the first sub-fixing member may also be disposed on the outer sidewall of the return annular groove. Furthermore, in some other embodiments, the second sub-fixing member may also be disposed on the inner sidewall of the return annular groove. Moreover, in some other embodiments, both the first and second sub-fixing members may be disposed on the inner sidewall of the return annular groove, or both may be disposed on the outer sidewall of the return annular groove.

[0079] See Figures 9 to 11 The vehicle frame 200 provided in one embodiment of this application includes a main body 210, a rotating assembly 220 rotatably connected to the main body 210, and a steering assist return mechanism 100.

[0080] In the aforementioned frame 200, when the slider is in the return-to-center state, both ends of the elastic element abut against both ends of the fixed element, resulting in a larger central angle for the elastic element. As the slider moves circumferentially along the return-to-center groove, the compression ratio of the elastic element is reduced, thus decreasing the degree of deformation, lowering the risk of elastic failure, and increasing the service life of the elastic element.

[0081] See Figure 10 and Figure 11 In this embodiment, the main body 210 and the rotating component 220 are fixedly connected via a bowl assembly 230, and the bowl assembly 230 is fixedly connected to the main body 210. A plug-in 231 is provided on the bowl assembly 230. A slot 1322 matching the plug-in 231 is provided on the slider 132. The plug-in 231 is inserted into the slot 1322. It is understood that in other embodiments, the main body and the slider can be fixedly connected by other connection methods, or the main body and the slider can be directly connected; this is not limited here.

[0082] See Figure 10 and Figure 11 In this embodiment, the first connecting structure 110 is sleeved on the rotating component 220 and is interference-fitted with the rotating component 220. It is understood that in other embodiments, the first connecting structure and the rotating component can also be fixedly connected by other connection methods. The first connecting structure and the rotating component can also be indirectly fixedly connected by other structures, which is not limited here.

[0083] Another embodiment of this application also provides a scooter, which includes the frame provided in this application.

[0084] In the aforementioned scooter, when the slider is in the centered position, both ends of the elastic element abut against both ends of the fixed element, resulting in a larger central angle for the elastic element. As the slider moves circumferentially along the centered groove, the compression ratio of the elastic element is reduced, decreasing its deformation and the risk of elastic failure, thus increasing its service life.
