[0002] With the development of the national economy and the continuous improvement of living standards, vehicles are becoming increasingly important in daily life and travel. To meet the needs of convenience and entertainment, motorcycles have also become a popular choice for transportation. Motorcycles are equipped with gearboxes to adapt to different driving conditions, and these gearboxes contain shifting mechanisms. Users can switch between different gears by pressing or hooking the pedal, thereby controlling the gearbox's output. Existing shifting mechanisms mainly include continuous drive and discontinuous drive types. However, the shifting hub of existing continuous drive types is prone to over-displacement, resulting in poor reliability. Discontinuous drive types, on the other hand, occupy more space, hindering lightweight design and affecting the vehicle's range, thus leaving room for improvement. Utility Model Content

[0010] According to some embodiments of the present invention, the shifting mechanism includes a limiting part having a shifting post and two limiting protrusions. The two limiting protrusions protrude radially outward from the outer peripheral wall of the shifting limiting member and are spaced apart circumferentially. The first limiting member is located between the two limiting protrusions, and the elastic reset member elastically abuts against the shifting post and the first limiting member.

[0011] According to some embodiments of the present utility model, the shifting mechanism of the elastic reset member includes a main body and two reset parts, the two reset parts are connected to the main body, the main body is sleeved on the mounting shaft, and the shifting column and the first limiting member are located circumferentially between the two reset parts.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The following is for reference. Figures 1-4 The shifting mechanism 100 according to an embodiment of the present utility model has a simple structure, can reduce the space occupied, thereby improving weight reduction, extending the vehicle's range, and improving the user experience.

[0024] like Figures 1-4 As shown, a shift mechanism 100 according to an embodiment of the present invention includes: a shift drive structure 6, a shift limiter 1, a shift hub 3, a mounting shaft 4, and a reset assembly 5.

[0025] Both the shift limiter 1 and the shift hub 3 are sleeved on the outside of the mounting shaft 4 and distributed along the axial direction of the mounting shaft 4. The shift drive structure 6 is poweredly connected to the shift limiter 1 so as to drive the shift hub 3 to rotate through the shift limiter 1 to perform gear switching. The reset assembly 5 includes an elastic reset member 51 and a first limiter 52. The elastic reset member 51 is elastically pressed between the first limiter 52 and the shift limiter 1. The elastic reset member 51 is adapted to drive the shift limiter 1 to reset after the shift drive structure 6 pushes the shift limiter 1 to complete the gear switching.

[0026] The motorcycle is equipped with a gearbox to adapt to different driving conditions. The gearbox has a shift mechanism 100, which allows users to switch between different gears by stepping on or hooking the pedal, thereby controlling the output of the gearbox. The operation is simple and can meet different usage needs.

[0027] Specifically, the shift mechanism 100 is provided with a shift limiter 1, a shift hub 3, and a mounting shaft 4. The shift hub 3 is sleeved on the mounting shaft 4, and the shift limiter 1 is also sleeved on the mounting shaft 4, so that the shift limiter 1 and the shift hub 3 are coaxially arranged, and the shift limiter 1 can rotate relative to the mounting shaft 4. The shift mechanism 100 is also provided with a shift drive structure 6, which is poweredly connected to the shift limiter 1. That is, the shift drive structure 6 can drive the shift limiter 1 to rotate relative to the mounting shaft 4, and when the shift limiter 1 rotates, it can drive the shift hub 3 to rotate synchronously, thereby enabling gear switching through the shift hub 3.

[0028] Thus, the coaxial arrangement of the shift limiter 1 and the shift hub 3 reduces the space occupied by the shift mechanism 100 radially along the mounting shaft 4, facilitating its layout and improving its lightweight nature, thereby extending the vehicle's range. Furthermore, by fitting both the shift limiter 1 and the shift hub 3 onto the mounting shaft 4, the shift limiter 1 can directly drive the shift hub 3 to rotate, eliminating the need for additional linkage structures between them. This simplifies the structure of the shift mechanism 100, reduces product costs, minimizes the risk of power transmission failure, and ensures the reliability of the shift mechanism 100.

[0029] Furthermore, the shift mechanism 100 is also provided with a reset component 5. The reset component 5 can reset the shift limiter 1 after the shift limiter 1 completes the gear shift to ensure the reliability of the shift limiter 1. The reset component 5 is provided with an elastic reset component 51 and a first limiter 52. The elastic reset component 51 can be a torsion spring or the like. The elastic reset component 51 can also be sleeved on the mounting shaft 4. The elastic reset component 51 elastically presses against the first limiter 52 and the shift limiter 1, so that when the shift limiter 1 rotates relative to the mounting shaft 4, the shift limiter 1 can cause the elastic reset component 51 to undergo elastic deformation.

[0030] Thus, when the shift limiter 1 completes the gear shift, the shift drive structure 6 can stop the power transmission, so that the elastic reset member 51 can apply an elastic force to the shift limiter 1 to reset in order to restore its deformation. This allows the shift limiter 1 to be reset after the gear shift is completed, ensuring the reliability of the shift limiter 1 and improving the reliability of the shift process of the shift mechanism 100.

[0031] According to the embodiment of the present utility model, the shift mechanism 100 is designed so that the shift limiter 1 and the shift hub 3 are both sleeved on the outside of the mounting shaft 4 and distributed along the axial direction of the mounting shaft 4. This allows the shift limiter 1 to drive the shift hub 3 to rotate along the axial direction for gear switching. This avoids the need to set a separate linkage structure between the shift limiter 1 and the shift hub 3, thereby simplifying the structure, reducing product costs, reducing the space occupied by the shift mechanism 100, improving weight reduction, and thus improving the vehicle's range performance and user experience. Furthermore, the reset component 5 ensures the reliability of the shift mechanism 100, resulting in better performance and a wider range of applications.

[0032] In some embodiments, a lever 2 is provided between the shift limiter 1 and the shift hub 3, and the shift limiter 1 is adapted to drive the shift hub 3 to rotate unidirectionally through the lever 2 when rotating.

[0033] Specifically, the shift limiter 1 can drive the shift hub 3 to rotate synchronously to switch gears, and as... Figures 1-3 As shown, a lever 2 is provided between the shift limiter 1 and the shift hub 3. That is, the shift limiter 1, lever 2 and shift hub 3 are distributed along the axial direction of the mounting shaft 4. One end of the lever 2 can be connected to the shift limiter 1 by plugging or snapping, so that when the shift limiter 1 rotates, it can drive the lever 2 to rotate synchronously. The lever 2 is located between the shift limiter 1 and the shift hub 3. When the shift limiter 1 drives the lever 2 to rotate, the lever 2 can drive the shift hub 3 to rotate in one direction. The shift limiter 1 directly drives the shift hub 3 to switch gears through the lever 2, which can simplify the structure and reduce product costs.

[0034] Furthermore, when the shift limiter 1 rotates clockwise, the shift block 2 can drive the shift hub 3 to rotate clockwise to perform either upshifting or downshifting. When the shift limiter 1 resets counterclockwise, the shift block 2 can reset along with the shift limiter 1, while the shift hub 3 can maintain the switched gear. When the shift limiter 1 rotates counterclockwise, the shift block 2 can drive the shift hub 3 to rotate counterclockwise to perform either upshifting or downshifting. When the shift limiter 1 resets clockwise, the shift block 2 can reset along with the shift limiter 1, while the shift hub 3 can still maintain the switched gear, thus ensuring the reliability of the shift mechanism 100.

[0035] In some embodiments, the shift hub 3 has a receiving cavity 311 that opens toward the shift limiting member 1. The mounting shaft 4 passes through the receiving cavity 311. One end of the shift block 2 is engaged and limited with the shift limiting member 1, and the other end of the shift block 2 is located inside the receiving cavity 311. The inner wall of the receiving cavity 311 has a shift groove 312. The shift limiting member 1 is adapted to drive the shift block 2 to rotate around the mounting shaft 4 when rotating, so that at least a portion of the shift block 2 is placed in the shift groove 312 and drives the shift hub 3 to rotate unidirectionally.

[0036] Specifically, the shift hub 3 is provided with a receiving cavity 311, and as... Figure 1 As shown, the receiving cavity 311 is open to the shift limiter 1, and the mounting shaft 4 passes through the receiving cavity 311, so that the receiving cavity 311 can rotate around the mounting shaft 4. The shift block 2 is disposed between the shift limiter 1 and the shift hub 3, so that at least a portion of one end of the shift block 2 along the axial direction can extend into the receiving cavity 311. The shift limiter 1 has a locking groove on the side near the shift hub 3, and the other end of the shift block 2 along the axial direction can be locked in the locking groove, so that when the shift limiter 1 rotates, it can drive the shift block 2 to move circumferentially in the receiving cavity 311 through the locking groove.

[0037] Furthermore, such as Figure 1 and Figure 3 As shown, the inner wall of the receiving cavity 311 is formed with a shift groove 312. When the shift limiting member 1 rotates, it can drive the shift block 2 to move circumferentially, so that at least a part of the shift block 2 can be placed in the shift groove 312 to be circumferentially limited with the shift groove 312. This allows the shift block 2 to drive the shift hub 3 to switch gears through the shift groove 312. When the shift limiting member 1 is reset, it can drive the shift block 2 to rotate synchronously. At this time, the shift block 2 can be withdrawn from the shift groove 312, so that the shift block 2 can drive the shift hub 3 in one direction to ensure the reliability of gear switching of the shift hub 3.

[0038] And such as Figure 1 As shown, there are multiple shift grooves 312, which are distributed sequentially along the circumference. This allows the shift limiter 1 to rotate so that the shift block 2 can be placed in different shift grooves 312 each time it rotates, thereby enabling the shift block 2 to drive the shift hub 3 to switch between multiple gears and meet different usage requirements.

[0039] In some embodiments, there are two shift blocks 2, which are distributed circumferentially around the mounting shaft 4. The shift limiter 1 is adapted to switch the shift hub 3 clockwise by one of the two shift blocks 2 when rotating clockwise, and to switch the shift hub 3 counterclockwise by the other of the two shift blocks 2 when rotating counterclockwise.

[0040] Specifically, a lever 2 is provided between the shift limiter 1 and the shift hub 3, and as follows: Figure 1 and Figure 3 As shown, there are two shift blocks 2, both located within the receiving cavity 311 and circumferentially spaced around the mounting shaft 4. The two shift blocks 2 extend in different radial directions, allowing the shift limiting member 1 to drive the shift hub 3 in different directions via the two shift blocks 2. That is, when the shift limiting member 1 rotates clockwise, it can shift the shift hub 3 clockwise via one of the two shift blocks 2, and when the shift limiting member 1 rotates counterclockwise, it can shift the shift hub 3 counterclockwise via the other of the two shift blocks 2.

[0041] Furthermore, when the shift limiter 1 rotates clockwise, one of the two levers 2 can drive the shift hub 3 to rotate clockwise, thereby enabling the shift hub 3 to either upshift or downshift. When the shift limiter 1 resets, the lever 2 can be removed from the shift groove 312, allowing the shift hub 3 to maintain the current gear position. When the shift limiter 1 rotates counterclockwise, the other of the two levers 2 can drive the shift hub 3 to rotate counterclockwise, thereby enabling the shift hub 3 to either upshift or downshift. When the shift limiter 1 resets, the lever 2 can be removed from the shift groove 312, allowing the shift hub 3 to maintain the current gear position. The structure is simple and ensures the reliability of gear switching.

[0042] In some embodiments, the shift limiter 1 includes a power connection portion 11 and a limiter portion 12, which are radially distributed on both sides of the mounting shaft 4. The shift drive structure 6 is poweredly connected to the power connection portion 11, and the elastic reset member 51 is elastically pressed between the first limiter 52 and the limiter portion 12.

[0043] Specifically, such as Figures 1-2 As shown, the shift limiter 1 is provided with a power connection part 11 and a limit part 12. The power connection part 11 and the limit part 12 can be connected by welding or other means, or the power connection part 11 and the limit part 12 can be integrally formed, which can improve production efficiency and ensure the structural strength of the shift limiter 1. The shift drive structure 6 is poweredly connected to the power connection part 11, that is, the shift drive structure 6 can drive the power connection part 11, thereby causing the shift limiter 1 to rotate relative to the mounting shaft 4. The elastic reset member 51 can elastically press against the first limit member 52 and the limit part 12, so that the reset assembly 5 can reset and cooperate with the limit part 12.

[0044] Furthermore, the power connection part 11 and the limiting part 12 are radially distributed on both sides of the mounting shaft 4, that is, the shift drive structure 6 and the reset assembly 5 are respectively located on both sides of the mounting shaft 4, so as to avoid mutual interference between the shift drive structure 6 and the reset assembly 5 and ensure the operational reliability of the shift drive structure 6 and the reset assembly 5.

[0045] In some embodiments, the limiting portion 12 is formed with a toggle post 121 and two limiting protrusions 122. The two limiting protrusions 122 protrude radially outward from the outer peripheral wall of the shift limiting member 1 and are spaced apart circumferentially. The first limiting member 52 is located between the two limiting protrusions 122, and the elastic reset member 51 elastically abuts against the toggle post 121 and the first limiting member 52.

[0046] Specifically, the elastic reset member 51 elastically presses against the limiting part 12 and the first limiting member 52, and as follows: Figures 1-3 As shown, the limiting part 12 forms a limiting protrusion 122. The limiting protrusion 122 is formed on the outer peripheral wall of the limiting part 12 and protrudes outward in the radial direction. There are two limiting protrusions 122, which are distributed circumferentially. The first limiting member 52 is located between the two limiting protrusions 122, so that when the shift limiting member 1 rotates clockwise, one of the two limiting protrusions 122 can press against the first limiting member 52. When the shift limiting member 1 rotates counterclockwise, the other of the two limiting protrusions 122 can press against the first limiting member 52. When the limiting protrusion 122 presses against the first limiting member 52, the shift hub 3 can perform a gear shift, thereby avoiding the shift hub 3 from over-shifting and ensuring the reliability of gear shifting.

[0047] Furthermore, the limiting part 12 also has a toggle post 121, which is located circumferentially between two limiting protrusions 122. The first limiting member 52 can also be constructed as a limiting post. When the shift limiting member 1 is in the initial position, the limiting post and the toggle post 121 are radially opposite each other, and the elastic reset member 51 is elastically pressed between the first limiting member 52 and the toggle post 121, so that when the shift limiting member 1 rotates, it can drive the toggle post 121 to rotate, thereby causing the elastic reset member 51 to undergo elastic deformation, so as to ensure the reliability of the elastic reset member 51.

[0048] In some embodiments, the elastic reset member 51 includes a main body 511 and two reset parts 512. The two reset parts 512 are connected to the main body 511. The main body 511 is sleeved on the mounting shaft 4. The shift post 121 and the first limiting member 52 are located circumferentially between the two reset parts 512. One of the two reset parts 512 is adapted to elastically press against the shift post 121 when the shift limiting member 1 rotates, and the other of the two reset parts 512 is adapted to elastically press against the first limiting member 52 when the shift limiting member 1 rotates.

[0049] Specifically, such as Figure 1As shown, the elastic reset member 51 is provided with a main body 511 and a reset part 512. The main body 511 is sleeved on the mounting shaft 4, and a spacer 513 is provided between the main body 511 and the mounting shaft 4 to ensure the installation stability of the main body 511 and to avoid wear on the mounting shaft 4. There are two reset parts 512, both of which are connected to the main body 511. When the shift limit member 1 is in the initial position, the shifting post 121 and the first limit member 52 are located circumferentially between the two reset parts 512. When the shift limit member 1 rotates, one of the two reset parts 512 is adapted to elastically press against the shifting post 121 when the shift limit member 1 rotates, and the other of the two reset parts 512 is adapted to elastically press against the first limit member 52 when the shift limit member 1 rotates. This allows the shift limit member 1 to be elastically limited while the shifting post 121 can also be used to apply a reset elastic force to the shift limit member 1, ensuring the reliability of the shift limit member 1.

[0050] In some embodiments, the shift drive structure 6 includes a drive member 61 and a transmission gear set 62. At least a portion of the outer peripheral wall of the shift limit member 1 is configured as an input gear. The input gear meshes with the transmission gear set 62 for transmission. The drive member 61 is poweredly connected to the transmission gear set 62 to drive the input gear through the transmission gear set 62.

[0051] Specifically, the shift drive structure 6 can drive the shift limit member 1, and as... Figure 1 As shown, the shift drive structure 6 is provided with a drive component 61 and a transmission gear set 62. The drive component 61 can be configured as a drive motor, etc. The transmission gear set 62 is provided with multiple gears. The motor shaft of the drive component 61 is connected to the transmission gear set 62, so that the drive component 61 can drive the transmission gear set 62 to rotate, thereby adjusting the speed of the power output by the drive component 61 to meet different usage requirements.

[0052] Furthermore, at least a portion of the outer peripheral wall of the shift limiter 1 is constructed as an input gear, which can be used as... Figures 1-3 As shown, the outer peripheral wall of the power connection part 11 of the shift drive member 61 can be constructed as an input gear. The input gear meshes with the transmission gear set 62, so that the drive member 61 can drive the transmission gear set 62, which in turn can drive the input gear. Furthermore, by adjusting the direction of the drive member 61, the power output direction of the transmission gear set 62 can be adjusted, which in turn can adjust the rotation direction of the shift limit member 1. This allows the shift limit member 1 to drive the shift hub 3 to adjust upshifting or downshifting, ensuring reliable operation.

[0053] In some embodiments, the shift mechanism 100 further includes a pressing component 7, which is adapted to press against the outer peripheral wall of the shift hub 3 when the shift limit member 1 is reset by the elastic reset member 51.

[0054] Specifically, such as Figure 1 As shown, the shift mechanism 100 is also provided with a pressing assembly 7. The pressing assembly 7 is provided with a pressing elastic member 71, a connecting rod 72 and a limiting pressure plate 73. The pressing elastic member 71 elastically presses against one end of the connecting rod 72, and the limiting pressure plate 73 is rotatably installed on the other end of the connecting rod 72. The outer peripheral wall of the shift hub 3 is formed with a stop groove 313. The pressing elastic member 71 can elastically press against the connecting rod 72, so that the limiting pressure plate 73 is limited and pressed in the stop groove 313. Thus, when the elastic reset member 51 drives the shift limiting member 1 to reset, the shift hub 3 can still maintain the state after the gear shift, so as to ensure the reliability of the shift.

[0055] The shift hub 3 is equipped with a ratchet 31 and a hub body 32. Both the ratchet 31 and the hub body 32 are sleeved on the mounting shaft 4 and distributed along the axial direction. The ratchet 31 is located close to the shift limit member 1. The ratchet 31 and the hub body 32 can be connected by welding or other means. Figure 4 As shown, a limiting pin 33 extending axially is provided between the ratchet 31 and the hub body 32 so that the ratchet 31 and the hub body 32 rotate synchronously in the circumferential direction. The receiving cavity 311 is formed in the ratchet 31, and the shift groove 312 is formed on the outer peripheral wall of the ratchet 31. Multiple shift grooves 312 are formed and distributed circumferentially on the outer peripheral wall of the ratchet 31. This ensures that when the shift hub 3 rotates to multiple gears, the limiting pressure plate 73 can be limited and pressed against the corresponding shift groove 312 to ensure the reliability of the pressing assembly 7.

[0056] This utility model also proposes a vehicle.

[0057] The vehicle according to the embodiments of the present invention includes the gear shifting mechanism 100 described above. The vehicle may include a motorcycle, etc.

[0058] According to the vehicle of this utility model embodiment, a gear shifting mechanism 100 is provided. The gear shifting mechanism 100 is configured by sleeved gear shifting limiter 1 and gear shifting hub 3 on the outside of mounting shaft 4 and distributed along the axial direction of mounting shaft 4. This allows gear shifting limiter 1 to drive gear shifting hub 3 to rotate along the axial direction for gear shifting. This avoids the need to set a separate linkage structure between gear shifting limiter 1 and gear shifting hub 3, thereby simplifying the structure, reducing product cost, reducing the space occupied by gear shifting mechanism 100, improving weight reduction, and improving vehicle range performance and user experience. Furthermore, a reset component 5 is provided to ensure the reliability of gear shifting of gear shifting mechanism 100, resulting in better performance and wider applicability.
