Description

Technical Field

[0001] This invention belongs to the field of motorcycle auxiliary device technology, and relates to a motorcycle auxiliary support device. Background Technology

[0002] Motorcycles are typically large and heavy, requiring one foot to be on the ground to maintain balance when slowing down or coming to a stop, which can be strenuous for women with less strength. Unloading heavy loads can also be difficult due to the inability to raise the motorcycle's kickstand.

[0003] To address the aforementioned issues, various motorcycle support devices have emerged in the existing technology. However, these devices are generally installed in fixed positions on the motorcycle. Due to significant differences in chassis height, ground clearance, and frame structure among different brands and models of motorcycles, it is difficult to standardize the design of these support devices. Currently, most motorcycle support devices on the market require customized installation for specific models, which not only increases manufacturing and adaptation costs but also limits their widespread application across multiple models. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a motorcycle auxiliary support device that can be adapted to different motorcycles.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A motorcycle auxiliary support device includes a mounting plate, a drive motor located on one side of the mounting plate, a transmission box located on the other side of the mounting plate, a mounting shaft rotatably located in the transmission box and driven by the drive motor, and a mounting structure for mounting the mounting plate onto the motorcycle rear swingarm. The mounting shaft extends in the left-right direction, and the portion of the mounting shaft extending out of the transmission box is connected to a swing arm. The swing arm is equipped with rollers. The mounting plate has multiple mounting points arranged sequentially in the vertical direction. The mounting structure can select the appropriate mounting points according to the ground clearance of the motorcycle model to mount the mounting plate onto the motorcycle rear swingarm.

[0007] When the drive motor is working, it rotates the mounting shaft, which in turn causes the swing arm to swing, causing the rollers to fall to the ground or rise off the ground. The roller axis is parallel to the mounting shaft axis and also parallel to the motorcycle wheel axis. When the rollers contact the ground, they provide effective support for the motorcycle. Because the mounting point can be selected according to the motorcycle's ground clearance, the mounting plate can be installed on the motorcycle's rear swingarm, making it compatible with different motorcycle models.

[0008] In the above-mentioned motorcycle auxiliary support device, each of the mounting points includes a first through hole and a second through hole spaced apart in the vertical direction; the mounting structure includes a U-bolt and two locking nuts, the two free ends of the U-bolt passing through the first through hole and the second through hole in the corresponding mounting point respectively, and being locked and fixed by the locking nuts respectively, so as to clamp the rear swingarm of the motorcycle in the opening of the U-bolt.

[0009] The mounting plate can be detachably fixed to the rear rocker arm using U-bolts, lock nuts, and corresponding first and second through holes, making installation convenient and providing a good fixing effect.

[0010] In the aforementioned motorcycle auxiliary support device, the mounting plate has at least two mounting points at the same height, and all mounting points at the same height are arranged sequentially along the width direction of the mounting plate. The mounting plate can be fixed to the motorcycle's rear swingarm using two or more U-bolts, further improving the stability of the mounting plate.

[0011] In the above-mentioned motorcycle auxiliary support device, each of the mounting points includes a third through hole on the mounting plate, and the mounting structure includes a clamping plate on the other side of the motorcycle rear swingarm. The clamping plate has a fourth through hole corresponding to the third through hole. The clamping plate and the mounting plate are connected by bolts passing through the third through hole and the fourth through hole to clamp the motorcycle rear swingarm.

[0012] Four bolts are typically used to connect the clamping plate and the mounting plate to firmly clamp the motorcycle's rear swingarm, thereby achieving the purpose of stabilizing the mounting plate. This allows for non-destructive installation and is simple and convenient.

[0013] In the above-mentioned motorcycle auxiliary support device, a reducer is also provided on one side of the mounting plate. The shaft of the drive motor is connected to the input shaft of the reducer, and the output shaft of the reducer is connected to the mounting shaft through a transmission structure.

[0014] In the aforementioned motorcycle auxiliary support device, a worm gear and a worm are rotatably mounted inside the transmission box. The mounting shaft is coaxially and fixedly connected to the worm gear, and the worm is parallel to the output shaft of the reducer. The transmission structure is located between the worm and the output shaft of the reducer. Utilizing the self-locking characteristic of the worm gear, the swing frame can be held in its current position when the drive motor stops.

[0015] In the above-mentioned motorcycle auxiliary support device, the transmission structure includes a first gear coaxially fixed on the output shaft of the reducer, a second gear coaxially fixed on the worm gear, and a plurality of transmission gears disposed between the first gear and the second gear, wherein the first gear, the plurality of transmission gears and the second gear mesh in sequence.

[0016] When the drive motor is working, it drives the output shaft of the reducer to rotate, which in turn drives the first gear to rotate. The first gear drives the second gear to rotate through multiple transmission gears. The second gear drives the worm to rotate, and the worm drives the worm wheel to rotate, which in turn drives the mounting shaft to rotate.

[0017] To facilitate the installation of the transmission gears, an L-shaped support plate is installed on one side of the mounting plate. The drive motor and reducer are mounted on the L-shaped support plate, and some of the transmission gears are rotatably positioned on the side of the L-shaped support plate. A clearance opening is provided on the mounting plate for meshing transmission between gears.

[0018] In the above-mentioned motorcycle auxiliary support device, the free end of the swing frame is hinged to a first connecting rod, and a second connecting rod is rotatably provided on the mounting plate. The free end of the second connecting rod is hinged to the middle of the first connecting rod, and the roller is located at the free end of the first connecting rod.

[0019] The mounting plate, the swing frame, the first link, and the second link together form a four-bar linkage. When the mounting shaft drives the swing frame to swing, the four-bar linkage works in concert to make the rollers fall smoothly to contact the ground or lift up to leave the ground, thus achieving folding and retraction.

[0020] Compared with existing technologies, this motorcycle auxiliary support device has the following advantages:

[0021] By setting multiple sets of vertically arranged mounting points on the mounting plate and using a U-bolt structure, it can flexibly adapt to the rear swingarm height of different models without customization, significantly reducing manufacturing and adaptation costs. The clamping method using U-bolts and double through holes with locking nuts makes disassembly and assembly convenient, secure fixation reliable, and supports multi-point parallel installation, enhancing overall stability. The integrated layout of the drive, reduction, transmission and support mechanisms does not occupy extra space and does not affect the original appearance and passability of the motorcycle.

[0030] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0031] Example 1

[0032] like Figure 1 As shown and Figure 2 The motorcycle auxiliary support device shown includes a vertically arranged mounting plate 1, a drive motor 2 located on the side of the mounting plate 1 near the motorcycle, a transmission box 3 located on the side of the mounting plate 1 away from the motorcycle, a mounting shaft 4 rotatably located in the transmission box 3 and driven by the drive motor 2, and a mounting structure for mounting the mounting plate 1 onto the motorcycle's rear swingarm. The mounting shaft 4 extends along the left-right direction of the motorcycle. The shaft of the drive motor 2 is perpendicular to the axis of the mounting shaft 4. A swing arm 5 is fixed to the part of the mounting shaft 4 extending out of the transmission box 3. A rollable roller 6 is provided at the free end of the swing arm 5. The axis of the roller 6 is parallel to the axis of the mounting shaft 4.

[0033] like Figure 1 As shown, an L-shaped support plate is also installed on the side of the mounting plate 1 closest to the motorcycle. The drive motor 2 is mounted on the L-shaped support plate, and a reducer 9 is mounted on the L-shaped support plate. The shaft of the drive motor 2 is connected to the input shaft of the reducer 9, and the output shaft of the reducer 9 is connected to the mounting shaft 4 through a transmission structure.

[0034] In this embodiment, a worm gear and a worm are rotatably mounted inside the transmission box 3. The mounting shaft 4 is coaxially and fixedly connected to the worm gear. The worm is parallel to the output shaft of the reducer 9, and the transmission structure is located between the worm and the output shaft of the reducer 9. Utilizing the self-locking characteristic of the worm gear, the swing frame 5 can be held in its current state after the drive motor 2 stops.

[0035] Specifically, such as Figure 1As shown, the transmission structure includes a first gear 10 coaxially fixed on the output shaft of the reducer 9, a second gear 11 coaxially fixed on the worm, and a plurality of transmission gears 12 disposed between the first gear 10 and the second gear 11. The first gear 10, the plurality of transmission gears 12 and the second gear 11 mesh in sequence. Some of the transmission gears 12 are rotatably disposed on the side of the L-shaped support plate and have clearance openings on the mounting plate 1 for meshing transmission between gears.

[0036] When the drive motor 2 is working, it drives the output shaft of the reducer 9 to rotate, which in turn drives the first gear 10 to rotate. The first gear 10 drives the second gear 11 to rotate through multiple transmission gears 12. The second gear 11 then drives the worm to rotate, which in turn drives the worm wheel to rotate, thereby driving the mounting shaft 4 to rotate.

[0037] like Figure 1-3 As shown, the mounting plate 1 has multiple mounting points arranged in a vertical direction. The mounting structure can select the appropriate mounting point according to the vehicle model's ground clearance to install the mounting plate 1 onto the motorcycle's rear swingarm.

[0038] Each mounting point includes a first through hole 7 and a second through hole 8 spaced vertically. The mounting structure includes a U-bolt and two locking nuts. The two free ends of the U-bolt pass through the first through hole 7 and the second through hole 8 at the corresponding mounting point, and are locked in place by the locking nuts to clamp the motorcycle's rear swingarm within the opening of the U-bolt. This design facilitates installation and provides a good fixation effect.

[0039] like Figure 1-3 As shown, there are two mounting points at the same height on the mounting plate 1, and the two mounting points at the same height are arranged sequentially along the width direction of the mounting plate 1.

[0040] When the drive motor 2 is working, it drives the mounting shaft 4 to rotate. The mounting shaft 4 drives the swing arm 5 to swing, causing the roller 6 to fall to the ground or rise to leave the ground. Since the mounting plate 1 can be installed on the motorcycle's rear swing arm at the appropriate mounting point according to the motorcycle's ground clearance, it can be adapted to different models of motorcycles.

[0041] like Figure 4 As shown, in order to protect the drive motor 2, reducer 9, first gear 10, second gear 11, and transmission gear 12, two protective covers are provided on the outside. One protective cover is located on one side of the mounting plate 1 and is used to cover the drive motor 2, reducer 9, first gear 10, and part of the transmission gear 12 at the same time. The other cover is located on the other side of the mounting plate and is used to cover the other part of the transmission gear 12 and the second gear 11.

[0042] In use, this auxiliary support device is usually installed on both sides of the motorcycle. The auxiliary support devices on both sides are symmetrically arranged and installed on different rear swingarms of the motorcycle.

[0043] Example 2

[0044] The structural principle of this embodiment is basically the same as that of Embodiment 1, except that, as Figure 5 As shown, the roller 6 is not directly mounted on the swing frame 5, but is hinged to the free end of the swing frame 5 with a first connecting rod 13. A second connecting rod 14 is rotatably mounted on the mounting plate 1, and the free end of the second connecting rod 14 is hinged to the middle of the first connecting rod 13. The roller 6 is located at the free end of the first connecting rod 13. The mounting plate 1, the swing frame 5, the first connecting rod 13, and the second connecting rod 14 together constitute a four-bar linkage. When the mounting shaft 4 drives the swing frame 5 to swing, this four-bar linkage works in concert to make the roller 6 fall smoothly to contact the ground or lift up to detach from the ground. Figure 6 As shown, this enables folding and shrinking.

[0045] Example 3

[0046] The structural principle of this embodiment is basically the same as that of Embodiment 1, except that, as Figure 7 As shown, each mounting point includes four third through holes on the mounting plate 1. The mounting structure includes a clamping plate 15 on the other side of the motorcycle rear swingarm 16. The clamping plate 15 has four fourth through holes corresponding to the third through holes. The clamping plate 15 and the mounting plate 1 are connected by bolts passing through the third and fourth through holes to clamp the motorcycle rear swingarm 16. Four bolts are used to connect the clamping plate 15 and the mounting plate 1 to firmly clamp the motorcycle rear swingarm 16, thereby achieving the purpose of stably fixing the mounting plate 1. This is a non-destructive, simple, and convenient installation.

[0047] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
