[0025] Firstly, this utility model proposes a two-wheeled vehicle.

[0026] Please see Figures 1 to 5 In one embodiment of the present invention, the two-wheeled vehicle includes a frame 1 and a foot support mechanism 2 and a locking mechanism 3 disposed on the frame 1. The frame 1 has a front wheel and a rear wheel spaced apart. The foot support mechanism 2 is located between the front wheel and the rear wheel and includes a support member 21 and a linkage assembly 22. The support member 21 has a rotating part 211 and a supporting part 212. The rotating part 211 is rotatably connected to the frame 1 so that the support member 21 has a supported state and a retracted state relative to the frame 1. One end of the linkage assembly 22 is rotatably connected to the frame 1, and the other end is rotatably connected to the support member 21 to constrain the rotation angle of the support member 21. The locking mechanism 3 is used to lock the support member 21 and restrict its rotation. In the supported state, the supporting part 212 is away from the frame 1 to support the two-wheeled vehicle. In the retracted state, the supporting part 212 is located on the side of the rotating part 211 near the front wheel.

[0027] With this configuration, in the retracted state, the rear wheel, rotating part 211, support part 212, and front wheel are arranged sequentially along the length of the frame 1. When parking, the support part 212 can be rotated to move from the position near the front wheel to the position near the rear wheel, allowing the support part 21 to enter a supporting state for parking the two-wheeled vehicle. It can be understood that the entire support part 21 is stored under the frame 1, eliminating the need for it to be located on the outside of the frame 1, thus saving space and reducing the size of the two-wheeled vehicle. Furthermore, with the support part 212 located near the pedals in the retracted state, it facilitates the rider's unfolding and retraction in scenarios requiring manual rotation, making parking operations more convenient.

[0028] It should be noted that the rotating part 211 of the support member 21 and the frame 1 can be connected by a connecting shaft, bearing, universal joint, or other structural connection to allow the support member 21 to swing in a specific direction; no specific limitation is made here. Furthermore, the linkage assembly 22 can be configured as multiple linkages connected movably, with both ends connected to the frame 1 and the support member 21 respectively. The linkage assembly 22 is used to constrain the swing angle of the support member 21, preventing the support member 21 from having an excessively large unfolding angle or colliding with the frame 1. This helps improve the safety and support stability of the support member 21 and reduces wear between components.

[0029] Furthermore, a connecting shaft, bearing, universal joint, or other structural connection can be provided between the linkage assembly 22 and the frame 1 to allow the support member 21 to rotate within a specific angle range. The number of links in the linkage assembly 22 can be two, three, or more; there is no specific limitation, and it can be adapted according to actual needs. The locking mechanism 3 can be a spring locking mechanism 3, a mechanical lock 32, a button locking mechanism 3, a pin locking mechanism 3, etc., to restrict the rotation or unlocking of the support member 21. The support member 21 can be directly rotatably connected to the frame 1, or indirectly connected to the frame 1 through the locking mechanism 3; no specific limitation is made here. Furthermore, in this solution, if... Figure 6 As shown, the width direction is assumed to be the X-axis extension direction and the length direction is assumed to be the Y-axis extension direction.

[0030] like Figures 1 to 5 As shown, in one embodiment, the linkage assembly 22 includes a first linkage 221 and a second linkage 222. One end of the first linkage 221 is rotatably connected to the frame 1, and the other end of the first linkage 221 is rotatably connected to one end of the second linkage 222. The end of the second linkage 222 away from the first linkage 221 is rotatably connected to the support member 21. It should be noted that the frame 1 can be equipped with a fixed shaft, motor, or other structures to allow the first linkage 221 to rotate. In the retracted state, the end of the first linkage 221 away from the frame 1 extends towards the front wheel. When the support member 21 is extended to the supported state, the end of the first linkage 221 away from the frame 1 swings towards the rear wheel. The lengths of the first linkage 221 and the second linkage 222 constrain the swing amplitude of the support member 21 and can improve the structural strength of the foot support mechanism 2.

[0031] In this embodiment, the length of the first link 221 is less than the length of the second link 222, which avoids excessive swing amplitude of the second link 222, making it easier for the support member 21 to be retracted or extended. When the support member 21 is retracted, the first link 221 allows the support member 21 to be closer to the frame 1, reducing the space occupied; while when the support member 21 is extended, the second link 222 can more easily support the entire structure, keeping it stable. In addition, the connection position of the first link 221 to the frame 1 is located on the side of the rotating part 211 near the front wheel. In some other embodiments of this utility model, the connection position of the first link 221 to the frame 1 can also be located on the side of the rotating part 211 near the rear wheel, which is not specifically limited here.

[0032] from Figure 4 and Figure 5As shown, in one embodiment, the support member 21 is provided with a first fixed shaft 215, which is located between the rotating part 211 and the support part 212. The end of the second connecting rod 222 away from the first connecting rod 221 is rotatably connected to the first fixed shaft 215. It should be noted that the first fixed shaft 215 is located on the outward side of the support member 21, and the second connecting rod 222 is bent so that at least part of it is located on the outside of the support member 21. The second connecting rod 222 is rotatably connected to the first fixed shaft 215, which facilitates the unfolding and retraction of the support member 21. Furthermore, the support part 212 of the support member 21 is bent outward so that the second connecting rod 222 limits the support member 21 in the retracted state, preventing the support member 21 from colliding with the frame 1.

[0033] Furthermore, the first fixed shaft 215 is located between the rotating part 211 and the support part 212, so that the frame 1, the support member 21, the second connecting rod 222, the first connecting rod 221 and each rotating point are enclosed to form a polygonal structure, which helps to reduce the force required for the support member 21 to rotate and improve the smoothness of its unfolding or retraction.

[0034] like Figure 4 and Figure 5 As shown, in one embodiment, the foot support mechanism 2 further includes a first elastic element 23. One end of the first elastic element 23 is connected to the frame 1, and the other end is connected to the first fixed shaft 215. The elastic element is used to apply a force to the support member 21 so that the support member 21 is in a supported state or a retracted state. In this embodiment, the first elastic element 23 is set as a tension spring. One end of the first elastic element 23 is connected to the first rotating shaft, and the other end is connected to the frame 1. The first elastic element 23 is always in a stretched state and continuously applies a force to the support member 21 so that the support member 21 is kept in a supported state or a retracted state, preventing it from swinging arbitrarily.

[0035] During the switching between the supported and retracted states, the rotation of the support member 21 needs to overcome the resistance generated by the deformation of the first elastic member 23. It should be noted that, in addition to a tension spring, the first elastic member 23 can also be a gas spring, an elastic metal sheet, or other components, as long as it can generate an upward force on the support member 21 in both the supported and retracted states. No specific limitation is made here.

[0036] like Figure 4 and Figure 6As shown, in one embodiment, the support member 21 includes a connecting section 213 and two support sections 214 disposed at both ends of the connecting section 213. Rotating portions 211 and supporting portions 212 are respectively disposed at both ends of each support section 214. The two rotating portions 211 are arranged along the width direction of the frame 1. The foot support mechanism 2 includes two linkage assemblies 22 and two first elastic elements 23. Each support section 214 is connected to one linkage assembly 22 and one first elastic element 23. It is understood that the connecting section 213 and the two support sections 214 are an integral structure with higher structural strength. The two supporting portions 212, arranged along the width direction of the frame 1, provide stable support. The rotatable connection between the frame 1 and the rotating portions 211 of the two support sections 214 further enhances the stability of the rotating structure. The two linkage assemblies 22 and the two elastic elements can be respectively connected to the first fixed shaft 215 on the outer side of the two support sections 214 to prevent deformation or displacement of the support member 21 during use.

[0037] like Figure 1 As shown, in one embodiment, the frame 1 includes a rear fork 13 and a front fork (not shown). The front wheel is mounted on the front fork, and the rear wheel and kickstand mechanism 2 are mounted on the rear fork 13. In the retracted state, the rotating part 211 and the support part 212 are located between the rotation axis of the rear wheel and the rotation axis of the front wheel. The rear fork 13 is provided with a mounting hole 131 for mounting the rear wheel axle. (Referring to a reference...) Figure 3 In the retracted state, the entire support 21 is located between the rotation axis of the rear wheel and the rotation axis of the front wheel, which can save space occupied by the frame 1 on both sides in the width direction, thereby reducing the overall volume of the two-wheeled vehicle.

[0038] Furthermore, in this embodiment, the rotating part 211 of the support member 21 is located close to the rotation axis of the rear wheel, which makes the center of gravity of the two-wheeled vehicle more stable when parked. In addition, this structure can also prevent the front wheel of the two-wheeled vehicle from lifting up, especially when there are goods or people on the back seat of the two-wheeled vehicle, further improving the stability of the two-wheeled vehicle when parked.

[0039] like Figure 7 and Figure 8 As shown, in one embodiment, the locking mechanism 3 includes a mounting base 31 and a latch 32. The mounting base 31 is disposed on the frame 1, and the rotating part 211 is rotatably connected to the mounting base 31. The latch 32 is rotatably disposed on the mounting base 31 and has a locked position and an unlocked position. In the locked position, the latch 32 is used to limit the rotation of the support member 21 by abutting against it; in the unlocked position, the latch 32 is away from the support member 21. It should be noted that the mounting base 31 is disposed on the frame 1, and the rotating part 211 of the support member 21 is configured as a shaft structure and rotatably connected to the mounting base 31. The rotating part 211 is also provided with a protrusion 216. The latch 32 is used to limit the rotation of the support member 21 from the supported state to the retracted state by abutting against the protrusion 216 in the locked position.

[0040] When the support member 21 is in the supported state, the restriction on the support member 21 can be released by rotating the latch 32 from the locked position to the unlocked position, allowing the support member 21 to rotate from the supported state to the retracted state. It is understood that by setting the latch 32, the support member 21 can be locked in the supported state, preventing the support member 21 from rotating under external force and causing the two-wheeled vehicle to tip over, thus improving the protection of the two-wheeled vehicle. A connecting shaft is provided inside the mounting base 31; one end of the latch 32 is rotatably connected to this connecting shaft, enabling switching between the locked and unlocked positions.

[0041] In addition, such as Figure 7 As shown, in this embodiment, the latch 32 has a latch 321. The protrusion 216 of the support member 21 matches the shape of the latch 321. The latch 321 is used to hook the protrusion 216 to prevent the support member 21 from rotating counterclockwise, thus stabilizing it in the support state. The front end of the latch 321 is also provided with a guide slope. When the support member 21 switches from the retracted state to the support state, the protrusion 216 abuts against the guide slope, causing the latch 32 to rotate as a whole. After the support member 21 rotates to its position, the latch 321 hooks the protrusion 216. It should be noted that the latch 32 can be reset by using elastic springs, spring sheets, or other components connected to the mounting base 31, so that the latch 32 is in the locked position in both the support and retracted states. When the latch 32 is subjected to external force and rotates clockwise, it can enter the unlocked position. At this time, the protrusion 216 is not restricted. The reset structure of the latch 32 is not specifically limited here.

[0042] like Figure 8 As shown, in one embodiment, the mounting base 31 is provided with an abutment member 311, which abuts against the support member 21 in the supported state to limit the opening and closing angle of the support member 21. It should be noted that, in order to limit the support member 21 from over-extension, the abutment member 311 in the mounting base 31 can directly abut against the support member 21, cooperating with the first elastic member 23 to limit the support member 21 to a specific position, so that the support member 21 remains in the supported state. Furthermore, the abutment member 311 can also prevent the support member 21 from colliding with the mounting base 31, avoiding wear on components. In this embodiment, the abutment member 311 is made of rubber; of course, materials such as thermoplastic elastomers and foam can also be used, and no specific limitation is made here.

[0043] like Figure 8As shown, in one embodiment, the mounting base 31 is provided with a limiting post 33, and a buffer member 331 is sleeved on the limiting post 33. The buffer member 331 is used to abut against the support member 21 in the retracted state to prevent the support member 21 from moving towards the vehicle frame 1. It can be understood that when the support member 21 switches from the supported state to the retracted state, the first elastic member 23 continuously provides a force to drive the support member 21 to rotate. The limiting post 33 is used to abut against the support member 21 to prevent the support member 21 from hitting the vehicle frame 1 and damaging the paint. In addition, the buffer member 331 is elastic and can reduce the sound of the support member 21 hitting the limiting post 33 when retracted. The limiting post 33 and the abutment member 311 cooperate to limit the rotation angle of the support member 21.

[0044] like Figure 4 and Figure 8 As shown, in one embodiment, the two-wheeled vehicle further includes a pull cable 34 and a second elastic element 35. One end of the pull cable 34 is connected to the mounting base 31 via the second elastic element 35, and the other end of the pull cable 34 is located outside the mounting base 31. A latch 32 is connected to the pull cable 34. The pull cable 34 is used to drive the latch 32 to rotate and move from the locked position to the unlocked position under the action of external force. The second elastic element 35 is used to drive the latch 32 to reset. It should be noted that in this embodiment, the second elastic element 35 is set as a tension spring. The end of the pull cable 34 away from the second elastic element 35 is located along the frame 1 at the handlebars. A traction mechanism is provided on the handlebars to drive the pull cable 34 to move. At this time, the second elastic element 35 is stretched, and the latch 32 rotates from the locked position to the unlocked position. When the traction mechanism releases the pull cable 34, the second elastic element 35 rebounds and can drive the pull cable 34 and the latch 32 to reset.

[0045] In another embodiment, a controller and an electromagnet and a button electrically connected to the controller can be installed on the two-wheeled vehicle. The button is located on the handlebars. The end of the pull cable 34 away from the second elastic member 35 is connected to the electromagnet. The button can be triggered to send a signal to the controller. The controller controls the electromagnet to move the pull cable 34 according to the signal, so that the latch 32 rotates from the locked position to the unlocked position. This solution further simplifies the unlocking method of the support member 21. Therefore, the structure for pulling the pull cable 34 can be set according to requirements, and no specific limitation is made here.

[0046] It is understood that by setting the pull wire 34 and the second elastic element 35, the position of the buckle 32 can be quickly adjusted to lock or unlock the support member 21. Of course, in some other embodiments of this utility model, the traction mechanism can also be set on the frame 1. The specific structure and installation position are not limited, and selective installation can be carried out according to the unlocking requirements.

[0047] like Figure 4 and Figure 5As shown, in one embodiment, the frame 1 is provided with a second fixed shaft 11, and the end of the connecting rod assembly 22 away from the support member 21 is rotatably connected to the second fixed shaft 11. It should be noted that the support member 21 in this embodiment needs to be manually extended or retracted. By setting the second fixed shaft 11, the first connecting rod 221 in the connecting rod assembly 22 is rotatably connected to the second fixed shaft 11 to realize the swinging requirement of the connecting rod assembly 22. Its structure is simple, easy to manufacture and assemble, and can save costs.

[0048] like Figures 1 to 3 As shown, in one embodiment, the frame 1 is provided with a drive member 12, which is driven to connect to the support member 21 via a linkage assembly 22. The drive member 12 is used to drive the support member 21 to rotate and switch between a supported state and a retracted state. It should be noted that the drive member 12 can drive the first linkage 221 to rotate, and the first linkage 221 drives the support member 21 to switch between a supported state and a retracted state via a second linkage 222, eliminating the need for manual control and improving the convenience of parking the two-wheeled vehicle. The drive member 12 can be configured as a motor, hydraulic device, pneumatic device, etc., as long as it can drive the support member 21 to unfold or retract; the specific structure is not limited here.

[0049] like Figures 1 to 3 As shown, in one embodiment, the drive unit 12 includes a drive motor, and the two-wheeled vehicle also includes a position sensor 24 disposed on the drive motor. The position sensor 24 is used to detect the position of the support member 21 and send the detection signal to the drive motor. The drive motor drives the support member 21 to rotate clockwise or counterclockwise according to the detection signal. It can be understood that the drive motor drives the first link 221 to rotate, and the position sensor 24 on it can detect the angle of the first link 221 and thus determine the state of the support member 21. The drive motor executes the corresponding unfolding or retracting operation according to this information and in combination with the buttons on the handlebars, the mobile APP, or voice commands, thereby achieving precise control of the support member 21, enhancing the technological and high-end feel of the two-wheeled vehicle, and conforming to the development trend of intelligence.

[0050] Furthermore, the position sensor 24 can be a micro switch, Hall sensor, reed switch, rotary encoder, etc., and can be selected according to actual needs. In addition to being set on the drive component 12 to detect the first link 221, the position sensor 24 can also be set on the frame 1 or the locking mechanism 3 to directly detect the support component 21. No specific limitation is made here.

[0051] Secondly, this utility model proposes a foot support device 100, which is applied to a two-wheeled vehicle, such as... Figures 1 to 5The kickstand device 100 includes a frame 1, a kickstand mechanism 2, and a locking mechanism 3. The kickstand mechanism 2 includes a support member 21 and a linkage assembly 22. The support member 21 has a rotating part 211 and a supporting part 212. The rotating part 211 is rotatably connected to the frame 1. One end of the linkage assembly 22 is rotatably connected to the frame 1, and the other end is rotatably connected to the support member 21. The linkage assembly 22 is used to constrain the rotation angle of the support member 21 so that the support member 21 rotates to a specific support angle to support the two-wheeled vehicle. The locking mechanism 3 includes a mounting base 31 and a latch 32. The mounting base 31 is disposed on the frame 1. The rotating part 211 of the support member 21 is rotatably connected to the mounting base 31, and the latch 32 is rotatably connected to the mounting base 31. After the support member 21 is extended to the support angle, the latch 32 is used to lock the support member 21 to restrict the rotation of the support member 21. When it is necessary to retract the support member 21, the latch 32 rotates to unlock so that the support member 21 can rotate and be retracted.

[0052] Furthermore, the frame 1 has a first mounting portion for mounting the front wheel and a second mounting portion for mounting the rear wheel. The first mounting portion and the second mounting portion are respectively mounted holes 131 on the front fork and the rear fork 13 for mounting the wheel axle. The rotating portion 211 is rotatably connected to the frame 1 so that the support member 21 has a supported state and a retracted state relative to the frame 1. In order to make the kickstand device 100 more ergonomic, the rotating portion 211 of the support member 21 is located between the first mounting portion and the second mounting portion. In the retracted state, the support portion 212 of the support member 21 is located on the side of the rotating portion 211 facing the front wheel, making it easier for the user to control the extension and retraction of the support member 21. This structure also helps to optimize the size of the two-wheeled vehicle.

[0053] like Figures 1 to 5 As shown, in one embodiment, the linkage assembly 22 includes a first link 221 and a second link 222. The support member 21 is provided with a first fixed shaft 215. One end of the first link 221 is rotatably connected to the frame 1, and the other end of the first link 221 is rotatably connected to one end of the second link 222. The end of the second link 222 away from the first link 221 is rotatably connected to the first fixed shaft 215. It should be noted that the lengths of the first link 221 and the second link 222 constrain the swing amplitude of the support member 21 and can improve the structural strength of the foot support mechanism 2. The first fixed shaft 215 is located between the rotating part 211 and the support part 212 so that the frame 1, the support member 21, the second link 222, the first link 221, and each rotation point form a polygonal structure, which helps to reduce the force required for the support member 21 to rotate and improve the smoothness of its expansion or contraction.

[0054] from Figure 4 and Figure 5As shown, in one embodiment, the frame 1 is provided with a second fixed shaft 11, and the end of the second connecting rod 222 away from the first connecting rod 221 is rotatably connected to the second fixed shaft 11. In this embodiment, the support member 21 needs to be manually extended or retracted. By setting the second fixed shaft 11, the first connecting rod 221 in the connecting rod assembly 22 is rotatably connected to the second fixed shaft 11 to realize the swinging requirement of the connecting rod assembly 22. Its structure is simple, easy to manufacture and assemble, and can save costs.

[0055] like Figures 1 to 3 As shown, in one embodiment, the frame 1 is provided with a drive member 12. The drive member 12 is driven to the support member 21 via a linkage assembly 22. The drive member 12 is used to drive the linkage assembly 22 to move and cause the support member 21 to unfold or retract. The drive member 12 can drive the first linkage 221 to rotate, and the first linkage 221 drives the support member 21 to switch between unfolding and retraction via the second linkage 222. This eliminates the need for manual control and improves the convenience of parking the two-wheeled vehicle. The drive member 12 can be configured as a motor, hydraulic device, pneumatic device, etc.

[0056] like Figure 4 ,and Figure 8 As shown, in one embodiment, the foot support device 100 further includes a pull cable 34 and a second elastic element 35. One end of the pull cable 34 is connected to the mounting base 31 via the second elastic element 35, and the other end of the pull cable 34 is located outside the mounting base 31. A latch 32 is connected to the pull cable 34. The pull cable 34 is used to rotate the latch 32 under external force to unlock the support member 21, and the second elastic element 35 is used to reset the latch 32. By providing the pull cable 34 and the second elastic element 35, the position of the latch 32 can be quickly adjusted to lock or unlock the support member 21.

[0057] It should be noted that the foot support device 100 in the second aspect can be applied to a two-wheeled vehicle in any embodiment of the first aspect. Therefore, the two-wheeled vehicle has all the technical effects of the foot support device 100. Furthermore, more specific details about the structure of the foot support device 100 have been described in detail in the first aspect, and will not be repeated here.

[0058] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
