Description

Technical Field

[0001] This utility model relates to the field of two-wheeled vehicle technology, and in particular to a center stand assembly and a two-wheeled vehicle. Background Technology

[0002] The center stand is a key component in a two-wheeled vehicle used to complete the parking process. When parking is required, the rider steps on the center stand with their foot, pushes against the center stand from the back, and pulls the vehicle body backward, so that the vehicle body can be supported by the center stand as a fulcrum.

[0003] In related technologies, anti-collision balls are installed on the center stand to prevent it from colliding with the vehicle body (such as the rear swingarm) when it is retracted. However, the anti-collision balls in these technologies are inconvenient to install and remove, which is not conducive to later maintenance. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, one embodiment of this utility model proposes a center support assembly, which can effectively prevent the center support frame from bumping and rubbing against the vehicle body after it is retracted, and is easy to disassemble and assemble, which is beneficial for later maintenance.

[0006] Another embodiment of this utility model proposes a two-wheeled vehicle.

[0007] A central support assembly according to an embodiment of the present invention includes a central support frame and a limiting wheel. The central support frame is adapted to support a vehicle body. The limiting wheel is disposed at the top of the central support frame and is located outside the central support frame. The limiting wheel is rotatable relative to the central support frame, and at least its outer periphery is elastic.

[0008] According to the embodiment of the present invention, the center support assembly has a limiting wheel at the top of the center support frame. When the center support frame is retracted relative to the vehicle body, the rotatable limiting wheel and its elastic outer periphery buffer the impact force on the vehicle body when the limiting wheel contacts the vehicle body, thus separating the vehicle body from the center support frame. Since the limiting wheel is located at the top of the center support frame and on the outside of the center support frame, it can be easily disassembled and assembled, improving the efficiency of later maintenance. Therefore, compared with related technologies, the present invention can effectively avoid the collision and abrasion of the vehicle body after the center support frame is retracted, and is convenient to disassemble and assemble, which is beneficial to later maintenance.

[0009] In some embodiments, the central support assembly further includes a support and a rotating shaft. The support is disposed at the top of the central support frame and located outside the central support frame. The rotating shaft is connected to the support, and the limiting wheel is sleeved on the rotating shaft and is rotatable relative to the rotating shaft.

[0010] In some embodiments, the center support assembly further includes a connector disposed at the top of the center support frame and spaced apart from the limiting wheel, wherein the end of the connector away from the center support frame is adapted to be rotatably connected to the vehicle body.

[0011] In some embodiments, the connector and the limiting wheel are spaced apart in the axial direction of the rotating shaft, and the connector and the rotating shaft are spaced apart in a first direction, which is orthogonal to the axial and vertical directions of the rotating shaft.

[0012] In some embodiments, the limiting wheel is movable relative to the rotating shaft along the axial direction of the rotating shaft; the central support assembly further includes a limiting member, which is detachably connected to the rotating shaft and is used to limit the limiting wheel in the axial direction of the rotating shaft.

[0013] In some embodiments, the portion of the rotating shaft facing away from the support is provided with a limiting hole, the limiting hole extending radially through the rotating shaft, the limiting member fitting within the limiting hole and at least partially located outside the rotating shaft, the limiting member being a cotter pin.

[0014] In some embodiments, the central support frame includes a crossbeam and legs connected to each other, the connector and the limiting wheel are both located on the side of the crossbeam away from the legs, the legs are at least two and spaced apart along the extension direction of the crossbeam, and the extension direction of the crossbeam is consistent with the axial direction of the rotating shaft.

[0015] In some embodiments, the center support assembly further includes a pad having a first surface and a second surface arranged opposite each other in its thickness direction, the first surface of the pad being connected to the end of the leg away from the crossbeam, and the second surface of the pad being an arcuate surface that protrudes toward the side away from the leg.

[0016] In some embodiments, there are at least two connectors arranged at intervals along the extension direction of the crossbeam, and the limiting wheel is located between at least two of the connectors.

[0017] A two-wheeled vehicle according to an embodiment of the present invention includes a vehicle body and a center support assembly, wherein the center support assembly is the center support assembly described in any of the above embodiments, and the top end of the center support frame is rotatably connected to the vehicle body.

[0018] According to the embodiments of the present invention, the two-wheeled vehicle has a center support assembly designed as a center support structure with a limit wheel rotatably mounted on the top. This allows for easy installation and removal of the limit wheel from the center support frame. Under the buffering effect of the elastic outer periphery of the limit wheel, the collision between the center support structure and the vehicle body is effectively reduced. Therefore, compared with related technologies, the two-wheeled vehicle using this center support assembly can ensure the service life of the entire vehicle and reduce maintenance costs.

[0019] In some embodiments, the vehicle body includes a frame and a rear swingarm, the rear swingarm being rotatably connected to the frame, a center stand located below the rear swingarm, the center stand being rotatably connected to the frame to have a first position and a second position, in the first position, the center stand is adjacent to the rear swingarm, and a limiting wheel of the center stand assembly is in rolling contact with the bottom of the rear swingarm, in the second position, the center stand is away from the rear swingarm to support the frame.

[0020] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0038] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] like Figures 1 to 3 As shown, a central support assembly 100 according to an embodiment of this utility model includes a central support frame 1 and a limiting wheel 2. The central support frame 1 is adapted to support a vehicle body 200. The limiting wheel 2 is located at the top of the central support frame 1, on the outside of the central support frame 1. In other words, the limiting wheel 2 is arranged on the top outer side of the central support frame 1, reducing the impact of the central support frame 1 and other components on the vehicle body 200 on the disassembly and assembly of the limiting wheel 2. This allows the limiting wheel 2 to be manually replaced directly from the central support frame 1 without additional disassembly of other components or inverting the vehicle body 200 when wear occurs after prolonged use, thus reducing maintenance costs. The limiting wheel 2 is rotatable relative to the central support frame 1, allowing it to roll in contact with the vehicle body 200, ensuring uniform force distribution on the outer circumferential surface of the limiting wheel 2. At least the outer circumference of the limiting wheel 2 is elastic.

[0040] According to the embodiment of the present invention, the center support assembly 100 has a limiting wheel 2 arranged at the top of the center support frame 1. When the center support frame 1 is retracted relative to the vehicle body 200, the rotatable limiting wheel 2 and its elastic outer periphery buffer the impact force on the vehicle body 200 when the limiting wheel 2 comes into contact with the vehicle body 200. The limiting wheel 2 separates the vehicle body 200 from the center support frame 1. Since the limiting wheel 2 is located at the top of the center support frame 1 and on the outside of the center support frame 1, it can be easily disassembled and assembled, improving the efficiency of later maintenance. Therefore, compared with related technologies, the present invention can effectively avoid the collision and abrasion of the vehicle body 200 after the center support frame 1 is retracted, and is easy to disassemble and assemble, which is beneficial to later maintenance.

[0041] Specifically, the portion of the outer circumferential surface of the limiting wheel 2 that rolls into contact with the vehicle body 200 may be made of an elastic material; or the entire outer circumferential surface of the limiting wheel 2 may be made of an elastic material; or the limiting wheel 2 may be a rubber wheel.

[0042] like Figure 3 As shown, in some embodiments, the central support assembly 100 further includes a support 3 and a rotating shaft 4. The support 3 is located at the top of the central support frame 1 and outside the central support frame 1. The rotating shaft 4 is connected to the support 3. The limiting wheel 2 is sleeved on the rotating shaft 4 and can rotate relative to the rotating shaft 4, so that the limiting wheel 2 can rotate relative to the central support frame 1.

[0043] Understandably, the support 3 and the rotating shaft 4 work together to form a support structure for mounting the limiting wheel 2 on the central support frame 1. The way the limiting wheel 2 is mounted on the rotating shaft 4 further facilitates the installation and removal of the limiting wheel 2 on the support 3. At the same time, during later maintenance, only the damaged limiting wheel 2 needs to be replaced, which ensures the service life of the rotating shaft 4 and the support 3 and saves costs.

[0044] Specifically, the support 3 can be an L-shaped sheet metal part to ensure the support strength of the support 3 for the limiting wheel 2. The rotating shaft 4 can be a pin.

[0045] Furthermore, the pivot 4 can be detachably connected to the support 3 so that if either of the connected components fails, only the damaged part needs to be replaced to ensure the normal operation of the central support assembly 100, without having to scrap the entire central support assembly 100, thus effectively reducing the maintenance cost of the central support assembly 100.

[0046] like Figures 1 to 3 As shown, in some embodiments, the center support assembly 100 further includes a connector 5, which is disposed at the top of the center support frame 1 and spaced apart from the limiting wheel 2. The end of the connector 5 away from the center support frame 1 is adapted to be rotatably connected to the vehicle body 200 so that the center support frame 1 can be installed on the vehicle body 200 by the connector 5. The connector 5 may be a connecting lug that is welded or integrally formed on the center support frame 1.

[0047] It is understandable that arranging the connecting piece 5 and the limiting wheel 2 at intervals on the middle support frame 1 can prevent the connecting piece 5 and the limiting wheel 2 from interfering with each other, so as to realize the pivotal movement of the middle support frame 1 relative to the vehicle body 200, while ensuring that the limiting wheel 2 can play a limiting role after the middle support frame 1 is retracted relative to the vehicle body 200.

[0048] like Figures 1 to 3 As shown, in some embodiments, the connector 5 and the limiting wheel 2 are arranged at intervals along the axial direction of the rotating shaft 4. The connector 5 and the rotating shaft 4 are arranged at intervals in the first direction. Since the limiting wheel 2 is sleeved on the rotating shaft 4, the connector 5 and the limiting wheel 2 are also spaced apart from each other in the first direction. The first direction is orthogonal to the axial direction and the vertical direction of the rotating shaft 4, so as to further make the connector 5 and the limiting wheel 2 spatially staggered, ensuring convenient disassembly and maintenance in the later stage.

[0049] like Figures 1 to 3 As shown, in some embodiments, the limiting wheel 2 can move axially relative to the rotating shaft 4, so that the limiting wheel 2 can slide off the rotating shaft 4 axially to achieve the disassembly of the limiting wheel 2, or the limiting wheel 2 can be sleeved on the rotating shaft 4 axially to achieve the installation of the limiting wheel 2. The limiting wheel 2 can be coaxially sleeved on the rotating shaft 4.

[0050] The central support assembly 100 also includes a limiting member 6, which is detachably connected to the rotating shaft 4. The limiting member 6 is used to limit the limiting wheel 2 in the axial direction of the rotating shaft 4.

[0051] Understandably, since the limiting component 6 can be disassembled from the rotating shaft 4, it further facilitates the disassembly and maintenance of the limiting wheel 2 in the later stage. When one of the two connected components fails, only the corresponding damaged component needs to be replaced to achieve normal operation of the central support assembly 100, without scrapping the entire central support assembly 100, thus effectively reducing the maintenance cost of the central support assembly 100.

[0052] For example, the limiting member 6 can be inserted into the peripheral wall surface of the rotating shaft 4 or the end of the rotating shaft 4. To ensure a reliable connection between the two, the limiting member 6 can be threaded into the rotating shaft 4, or the limiting member 6 can be an elastic member, so as to use elastic force to lock the limiting member 6 into the rotating shaft 4. At least a part of the limiting member 6 needs to be located on the outside of the rotating shaft 4 to constrain the limiting wheel 2 along the axial direction of the rotating shaft 4 and prevent the limiting wheel 2 from falling off the rotating shaft 4 axially.

[0053] like Figure 3 As shown, in some embodiments, the portion of the rotating shaft 4 away from the support 3 is provided with a limiting hole 41. The limiting hole 41 penetrates the rotating shaft 4 radially. The limiting member 6 is fitted inside the limiting hole 41 and is at least partially located outside the rotating shaft 4. The limiting member 6 is a cotter pin.

[0054] Understandably, using cotter pins allows for quick assembly and disassembly of the limit wheel 2 on the rotating shaft 4, further improving the maintenance efficiency of the limit wheel 2 and reducing costs.

[0055] like Figures 1 to 3 As shown, in some embodiments, the central support frame 1 includes a crossbeam 11 and legs 12 connected to each other. The connector 5 and the limiting wheel 2 are both located on the side of the crossbeam 11 away from the legs 12. There are at least two legs 12, which are spaced apart along the extension direction of the crossbeam 11. The extension direction of the crossbeam 11 is consistent with the axial direction of the rotating shaft 4.

[0056] It is understandable that the crossbeam 11 and the support leg 12 cooperate to form the middle support frame 1 structure. The overall structure is simple. The arrangement of the connecting part 5 and the limiting wheel 2 on both sides of the crossbeam 11 can effectively avoid the interference of the support leg 12 on the disassembly and maintenance of the middle support frame 1 and the limiting wheel 2.

[0057] Specifically, the bottom ends of both the connector 5 and the support 3 can be connected to the top end of the crossbeam 11. For example, there may be two support legs 12, one connected to the first end of the crossbeam 11 and the other connected to the second end. In this case, the crossbeam 11 and the two support legs 12 can be integrally formed and arranged in a U-shape, ensuring the supporting performance of the central support frame 1 while further simplifying its overall structure. The outer contour of the cross section of each of the crossbeam 11 and the support leg 12 can be a circle, a square, or any closed curve, preferably a circle, to reduce manufacturing difficulty.

[0058] Additionally, the center stand assembly 100 may also include a connecting rod 13 and a foot pedal 14. One of the support legs 12, the portion facing away from the crossbeam 11, is connected at an angle to the connecting rod 13. The connecting rod 13 is located on the outside of the support leg 12, and its end facing away from the support leg 12 is connected to the foot pedal 14, allowing the rider to use the foot pedal 14 to raise or lower the center stand 1 relative to the vehicle body 200. A connecting rib 15 may also be provided between the connecting rod 13 and the support leg 12 to enhance the structural strength between them. The connecting rib 15 may have openings to allow for venting during welding.

[0059] like Figures 1 to 3 As shown, in some embodiments, the central support assembly 100 further includes a pad 7 having a first surface and a second surface arranged opposite each other in its thickness direction. The first surface 71 of the pad is connected to the end of the support leg 12 away from the crossbeam 11, and the second surface 72 of the pad is an arcuate surface that protrudes toward the side away from the support leg 12.

[0060] Understandably, designing the second surface 72 of the pad as an arc surface allows the middle support 1 to smoothly transition from being erected to being retracted, making the transition from the erected support state to the retracted state smoother and less strenuous.

[0061] Specifically, the pad 7 may be a sheet metal part, with a hole at its bottom to allow for venting during welding.

[0062] Furthermore, the first surface 71 of the pad is concave to the second surface 72 of the pad and the two are parallel to each other, so as to simplify the structure of the pad 7 and reduce the difficulty of production.

[0063] Furthermore, the area of ​​the second surface 72 of the pad is larger than the cross-sectional area of ​​the support leg 12, so as to further increase the contact area between the pad 7 and the ground and ensure the reliable support of the central support frame 1 for the vehicle body 200.

[0064] Furthermore, the pad 7 can be detachably connected to the outrigger 12 so that if one of the connected parts fails, only the damaged part needs to be replaced to ensure the normal operation of the center support assembly 100, without scrapping the entire center support assembly 100, thus further reducing the maintenance cost of the center support assembly 100.

[0065] like Figures 1 to 3 As shown, in some embodiments, there are at least two connectors 5 and they are spaced apart along the extension direction of the crossbeam 11 to ensure that the central support frame 1 can be stably pivotally connected to the vehicle body 200, and the limiting wheel 2 is located between at least two connectors 5.

[0066] like Figure 4 As shown, a two-wheeled vehicle 10 according to an embodiment of the present invention includes a vehicle body 200 and a center support assembly 100. The center support assembly 100 is the center support assembly 100 of any of the above embodiments. The top end of the center support frame 1 is rotatably connected to the vehicle body 200. Specifically, the connecting member 5 is rotatably connected to the vehicle body 200.

[0067] According to the embodiment of the present invention, the two-wheeled vehicle 10 has a center support assembly 100 designed as a center support structure with a limiting wheel 2 rotatably mounted on the top. This allows for easy assembly and disassembly of the limiting wheel 2 on the center support frame 1. Under the buffering effect of the elastic outer periphery of the limiting wheel 2, the collision between the center support structure and the vehicle body 200 is effectively reduced. Therefore, compared with related technologies, the two-wheeled vehicle 10 using this center support assembly 100 can ensure the service life of the entire vehicle and reduce maintenance costs.

[0068] like Figure 3 and Figure 4 As shown, in some embodiments, the vehicle body 200 includes a frame 8 and a rear swingarm 9, the rear swingarm 9 being rotatably connected to the frame 8, and a center support 1 located below the rear swingarm 9. The center support 1 is rotatably connected to the frame 8 to have a first position and a second position. In the first position, the center support 1 is adjacent to the rear swingarm 9, and the limiting wheel 2 of the center support assembly 100 is in rolling contact with the bottom of the rear swingarm 9. In the second position, the center support 1 is away from the rear swingarm 9 to support the frame 8.

[0069] It is understandable that when the center support 1 is in the first position, it can be retracted relative to the frame 8. When the body 200 is shock-absorbing and extending, and the rear swingarm 9 pivots around its mounting point (generally 2.5°-14°), compared to the rear swingarm 9 in related technologies, which is prone to colliding with the center support 1 below it during pivoting, the center support 1 of this utility model is equipped with a limiting wheel 2. The limiting wheel 2 makes rolling contact with the bottom of the rear swingarm 9, so it can form a relative displacement with the rear swingarm 9, thereby effectively protecting the surface coating of the rear swingarm 9.

[0070] Specifically, the pivot point of the center stand 1 on the frame 8 is separated from the pivot point of the rear swingarm 9 on the frame 8. That is, the rotation axis 4 of the center stand 1 and the rotation axis 4 of the rear swingarm 9 are not concentric. Therefore, when the body 200 is shock-absorbing and extending (that is, when the rear wheel is shock-absorbing relative to the frame 8), the limiting wheel 2 will have relative movement relative to the rear swingarm 9. The rotational angular velocities are different, so a relative displacement will be formed between the limiting wheel 2 and the rear swingarm 9.

[0071] Furthermore, the connector 5 is provided with a hook pin 51, and the two-wheeled vehicle 10 also includes an elastic element (not shown in the figure). The first end of the elastic element is connected to the hook pin 51, and the second end of the elastic element is connected to the frame 8. The elastic element presses the central support frame 1 from the second position toward the first position.

[0072] It is understandable that the limiting wheel 2 makes rolling contact with the bottom of the rear swingarm 9, that is, the limiting wheel 2 hits the bottom of the rear swingarm 9, which can prevent the center support 1 from retracting at too large an angle. The center support 1 hits other peripheral parts of the vehicle body 200, which can also keep the elastic element under tension, so that the center support 1 will not easily sway up and down.

[0073] Specifically, the pin 51 can be located below the pivot point of the center support 1 on the frame 8. The elastic element can be a spring.
