Description

Technical Field

[0001] This utility model belongs to the technical field of motorcycle auxiliary devices, 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 this end, a Chinese patent discloses an auxiliary wheel device for two-wheeled motorcycles [authorization announcement number CN213057296U]. The output shaft of the worm gear motor forms a kinematic pair with the worm and the movable rod assembly through the worm and the movable rod assembly. When the movable rod assembly moves, it drives the torsion spring mounting arm to rotate in a circular linkage motion around the horizontal main shaft. Since the torsion spring mounting arm is fixed to the end of the first driven arm and the second driven arm is symmetrically arranged on the other end of the horizontal main shaft, when the torsion spring mounting arm rotates, it will drive the first driven arm and the second driven arm connected to the horizontal main shaft to rise or fall simultaneously.

[0004] Because both training wheels need to leave or touch the ground at the same time, when used on some sloping roads or roads with different heights on the left and right, the support feet on both sides cannot touch the ground at the same time, and cannot effectively support the motorcycle. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a motorcycle auxiliary support device that provides good support for motorcycles.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A motorcycle auxiliary support device includes a housing, a first rotating shaft rotatably disposed within the housing, and a second rotating shaft coaxially disposed with the first rotating shaft. A first bracket is provided at one end of the first rotating shaft extending out of the housing, and a second bracket is provided at one end of the second rotating shaft extending out of the housing. The first rotating shaft and the second rotating shaft are connected by a differential structure disposed within the housing. The housing is provided with a drive structure for driving the differential structure.

[0008] In use, the drive structure drives the differential structure, which in turn rotates the first and second shafts. This causes the first and second supports to swing downwards until their lower ends touch the ground, thus supporting the motorcycle. When used on sloping surfaces or surfaces with varying heights on either side, one support will contact the ground first. Due to the differential structure, the other support will also contact the ground, ensuring that both supports are on the ground and providing support to the motorcycle from two directions.

[0009] In the aforementioned motorcycle auxiliary support device, the differential structure includes a frame, two planetary gears rotatably mounted on the frame, and two sun gears respectively meshing with the planetary gears. The two planetary gears are coaxially arranged, and the two sun gears are coaxially arranged. The centerline of the planetary gears is perpendicular to the centerline of the sun gears. An output shaft coaxially fixed to the sun gear and rotatably engages with the housing. The frame is rotatably mounted on one of the output shafts. The drive structure drives the frame to rotate around the output shaft. The first rotating shaft is drive-connected to one of the output shafts, and the second rotating shaft is drive-connected to the other output shaft.

[0010] When the drive structure is working, it drives the frame to rotate around the output shaft. Through the action of planetary gears and sun gears, it drives the two output shafts to rotate. The two output shafts then drive the first and second rotating shafts to rotate, thereby realizing the swinging of the first and second supports. When encountering uneven road surfaces, one support will contact the ground first, and the other support will continue to swing downwards under the action of the drive structure and differential structure, and will also contact the ground.

[0011] In the above-mentioned motorcycle auxiliary support device, each output shaft is coaxially provided with a worm gear, and two worm wheels are rotatably fitted inside the housing, each meshing with a different worm gear. Each worm wheel is coaxially provided with a first bevel gear. A second bevel gear meshing with one of the first bevel gears is coaxially fixed to the first rotating shaft, and a third bevel gear meshing with the other first bevel gear is coaxially fixed to the second rotating shaft.

[0012] When the drive structure is working, it drives the two worm gears to rotate in the same direction, which in turn drives the two worm wheels to rotate in the same direction, ultimately achieving the same-direction rotation of the first and second shafts. Because the worm gears drive the worm wheels, a self-locking function is achieved when the drive structure stops, preventing the first and second supports from rotating automatically and effectively improving the support effect.

[0013] In the above-mentioned motorcycle auxiliary support device, the drive structure includes a motor housed in the housing, a drive gear on the motor shaft, and a driven gear on the frame. The driven gear is coaxially arranged with the output shaft, and the drive gear meshes with the driven gear.

[0014] A switch for controlling the forward and reverse rotation of the motor is installed on the motorcycle's handlebars. This switch is a time-delay switch; after being pressed, the motor operates for a period of time and then automatically stops. During this period of motor operation, the horizontally extending first / second bracket can be lowered to contact the ground. This switch has two positions: a forward switch and a reverse switch. When it is necessary to raise the first and second brackets, the motor is reversed using the two-position switch.

[0015] In the aforementioned motorcycle auxiliary support device, the differential structure includes a frame, two planetary gears rotatably mounted on the frame, and two sun gears respectively meshing with the planetary gears. The two planetary gears are coaxially arranged, and the two sun gears are coaxially arranged. The center line of the planetary gears is perpendicular to the center line of the sun gears. An output shaft that rotatably engages with the housing is coaxially fixed to the sun gear. The frame is rotatably mounted on one of the output shafts. The drive structure drives the frame to rotate around the output shaft. The first rotating shaft is coaxially fixed to one of the output shafts, and the second rotating shaft is coaxially fixed to the other output shaft.

[0016] When the drive structure is working, it drives the frame to rotate around the output shaft. Through the action of planetary gears and sun gears, it drives the two output shafts to rotate. The two output shafts then drive the first and second rotating shafts to rotate, thereby realizing the swinging of the first and second supports. When encountering uneven road surfaces, one support will contact the ground first, and the other support will continue to swing downwards under the action of the drive structure and differential structure, and will also contact the ground.

[0017] In the above-mentioned motorcycle auxiliary support device, ratchet wheels are coaxially provided on both output shafts, and two pawls are provided in the housing, each corresponding to one of the ratchet wheels. The pawls mesh with the ratchet wheels opposite them, and the housing is provided with a ratchet unlocking device for unlocking.

[0018] The pawl, under the action of a spring, engages with the ratchet, restricting the ratchet's unidirectional rotation and causing the first and second supports to swing downwards only. A pull cable is connected to the ratchet unlocking mechanism, with its outer end extending to the motorcycle's handlebars. To unlock, pulling the cable rotates the ratchet unlocking mechanism, causing the pawl to disengage from the ratchet and the output shaft to release its restraint. This allows the first and second supports to reset. Alternatively, the ratchet unlocking mechanism can be connected to the motorcycle's foot pedals; pressing the foot pedals unlocks the mechanism.

[0019] In the aforementioned motorcycle auxiliary support device, the drive structure includes a rotating sleeve rotatably disposed within a housing and rotatably sleeved on one of the output shafts, an intermediate shaft rotatably disposed within the housing and parallel to the output shaft, a first gear coaxially disposed on the rotating sleeve, a second gear coaxially disposed on the intermediate shaft, a third gear coaxially disposed on the intermediate shaft, and a fourth gear disposed on the frame. The third gear meshes with the fourth gear. The rotating sleeve is also provided with a foot pedal located outside the housing. A torsion spring for resetting the rotating sleeve is provided between the rotating sleeve and the housing. A transmission structure is provided between the first gear and the second gear. When the foot pedal swings downward, the transmission structure connects the first gear and the second gear.

[0020] When the first and second supports need to be supported, step down on the foot pedal to make it swing downwards, thereby driving the rotating sleeve to rotate in the same direction. At this time, the torsion spring is pre-tensioned and under the action of the transmission structure, the first gear and the second gear are connected, thereby driving the intermediate shaft to rotate. Through the third and fourth gears, the frame is driven to rotate, thus realizing the rotation of the two output shafts, thereby causing the first and second supports to swing downwards.

[0021] When the foot pedal is released, the rotating sleeve rotates in the opposite direction under the action of the torsion spring, thereby driving the first gear to rotate in the opposite direction. Under the action of the first gear, the transmission structure is disengaged, and the first gear will not drive the second gear to rotate, thus avoiding the output shaft from reversing. Together with the ratchet and pawl, the first and second supports are kept in the current support state.

[0022] In the aforementioned motorcycle auxiliary support device, the housing is provided with two oppositely arranged guide grooves. The transmission structure includes a drive shaft and a transmission gear coaxially mounted on the drive shaft. The drive shaft is parallel to the intermediate shaft. One end of the drive shaft is slidably engaged in one of the guide grooves, and the other end of the drive shaft is slidably engaged in the other guide groove. When the drive shaft is located at the lower end of the guide groove, the transmission gear only meshes with the first gear. When the pedal is pressed down, the first gear pushes the transmission gear, thereby moving the drive shaft to the upper end of the guide groove. When the drive shaft is located at the upper end of the guide groove, the transmission gear meshes with the first gear and the second gear respectively.

[0023] Two guide grooves are respectively set on different sides of the housing. The width of the guide grooves is equal to the outer diameter of the drive shaft, allowing the drive shaft to slide only within the guide grooves. To prevent axial movement of the drive shaft, an axial limit can be set between the drive shaft and the housing. When the drive shaft is at the lower end of the guide groove, the drive gear only meshes with the first gear. At this time, the drive gear and the first gear are deeply engaged. When the first gear rotates under the action of the foot pedal, it can push the drive shaft to slide within the guide groove, thereby moving the drive shaft to the upper end of the guide groove. During this process, the drive gear gradually meshes with the second gear without disengaging from the first gear. When the first gear rotates, it will drive the second gear to rotate through the drive gear, thereby realizing the swinging of the first and second supports.

[0024] When the first gear swings in the opposite direction, the drive shaft slides from the upper end of the guide groove to the lower end of the guide groove under its own weight, and the drive gear disengages from the second gear.

[0025] In the above-mentioned motorcycle auxiliary support device, the number of teeth of the first gear is greater than the number of teeth of the transmission gear, and the number of teeth of the transmission gear is greater than the number of teeth of the second gear.

[0026] The third and fourth gears have similar numbers of teeth. Due to the large gear ratio, the output shaft can rotate a large angle when the foot pedal rotates a small angle.

[0027] In the above-mentioned motorcycle auxiliary support device, a return spring is provided between the first bracket and the housing, and a return spring is also provided between the second bracket and the housing.

[0028] When the first and second supports swing downwards, the return spring is under tension. To reset, the ratchet pawl is unlocked, and the return spring allows the first and second supports to reset. During the unlocking process, the transmission structure is disengaged, meaning the first and second gears are disengaged, and the rotating sleeve will not rotate.

[0029] Compared with existing technologies, this motorcycle auxiliary support device has the following advantages:

[0030] During installation, the motorcycle's kickstand is removed, and the housing is then installed in the kickstand mounting position without damaging the motorcycle's structure, making installation convenient. It has a wide range of applications and can be used in various working conditions, such as providing effective support for motorcycles on uneven roads, during loading and unloading of heavy goods, while waiting at traffic lights, or while riding on snow. The first and second supports can be quickly swung downwards, providing excellent support for the motorcycle. With its reasonable structural design and low manufacturing cost, it can be widely adopted. Attached Figure Description

[0038] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0039] Example 1

[0040] like Figure 1 The motorcycle auxiliary support device shown includes a housing 1, a first rotating shaft 2 rotatably disposed within the housing 1, and a second rotating shaft 3 coaxially disposed with the first rotating shaft 2. The first rotating shaft 2 and the second rotating shaft 3 extend horizontally in the left-right direction. To facilitate better rotation, the first rotating shaft 2 and the second rotating shaft 3 can be rotatably mounted on the housing 1 via bearings.

[0041] like Figure 1As shown, a first rotating shaft 2 extends from the left side of the housing 1. A first bracket 4 is provided at the left end of the first rotating shaft 2 extending from the housing 1. A first support wheel is provided on the first bracket 4. The axis of the first support wheel in the supported state is parallel to the axis of the motorcycle wheel. A second rotating shaft 3 extends from the right side of the housing 1. A second bracket 5 is provided at the right end of the second rotating shaft 3 extending from the housing 1. A second support wheel is provided on the second bracket 5. The axis of the second support wheel in the supported state is parallel to the axis of the motorcycle wheel. The rotation of the first rotating shaft 2 can cause the first bracket 4 to swing, thereby supporting the first support wheel on the ground; the rotation of the second rotating shaft 3 can cause the second bracket 5 to swing, thereby supporting the second support wheel on the ground.

[0042] To provide support for motorcycles on surfaces with slopes or unevenness on both sides, such as... Figure 1 As shown, the first rotating shaft 2 and the second rotating shaft 3 are connected by a differential transmission structure located inside the housing 1. In order to enable the movement of the first support 4 and the second support 5, a drive structure for driving the differential structure is provided on the housing 1.

[0043] In use, the drive structure drives the differential structure to rotate, which in turn drives the first shaft 2 and the second shaft 3 to rotate. This causes the first bracket 4 and the second bracket 5 to swing downwards until their lower ends touch the ground, thus supporting the motorcycle.

[0044] When used on sloping roads or roads with different heights on the left and right, one of the brackets will contact the ground first. Due to the differential structure, the other bracket will also contact the ground under the action of the drive mechanism, so that both the first bracket 4 and the second bracket 5 are supported on the ground, thus supporting the motorcycle from two directions.

[0045] like Figure 1 As shown, the differential structure includes a frame 6, two planetary gears 7 rotatably mounted on the frame 6, and two sun gears 8 meshing with the planetary gears 7 respectively. The two planetary gears 7 are coaxially arranged, and the two sun gears 8 are coaxially arranged with their axes extending horizontally in the left-right direction. The centerline of the planetary gears 7 is perpendicular to the centerline of the sun gears 8. An output shaft 9 coaxially fixed to the sun gear 8 and rotatably engages with the housing 1. The two output shafts 9 extend horizontally in the left-right direction and are rotatably mounted on the housing 1 via bearings. The frame 6 is rotatably sleeved on the output shaft 9 located on the right side. When the drive structure is working, it can drive the frame 6 to rotate around the output shaft 9. The first rotating shaft 2 is drive-connected to the output shaft 9 located on the left side, and the second rotating shaft 3 is drive-connected to the output shaft 9 located on the right side.

[0046] When the drive structure is working, it drives the frame 6 to rotate around the output shaft 9. Through the action of the planetary gear 7 and the sun gear 8, it drives the two output shafts 9 to rotate. The two output shafts 9 then drive the first rotating shaft 2 and the second rotating shaft 3 to rotate, thereby realizing the swing of the first bracket 4 and the second bracket 5. When encountering uneven road surfaces, one bracket will contact the ground first, and the other bracket will continue to swing downward under the action of the drive structure and the differential structure, and will also contact the ground.

[0047] like Figure 1 As shown, each output shaft 9 is coaxially equipped with a worm gear 10. Inside the housing 1, two worm wheels 11 are rotatably fitted, each meshing with a different worm gear 10. To install the worm wheels 11, they are coaxially fixed to a support shaft (not shown in the figure). The support shaft is rotatably mounted inside the housing 1 via bearings. For transmission, as... Figure 1 As shown, each worm gear 11 is coaxially equipped with a first bevel gear 12. A second bevel gear 13, which meshes with the first bevel gear 12 located on the left side, is coaxially fixed to the first rotating shaft 2. A third bevel gear 14, which meshes with the first bevel gear 12 located on the right side, is coaxially fixed to the second rotating shaft 3. The second bevel gear 13 and the third bevel gear 14 face the same direction and rotate in the same direction, thus achieving the same-direction rotation of the first support 4 and the second support 5. When the drive structure is working, it drives the two worm gears 10 to rotate in the same direction, thereby driving the two worm gears 11 to rotate in the same direction, ultimately achieving the same-direction rotation of the first rotating shaft 2 and the second rotating shaft 3. Since the worm gears 10 drive the worm gears 11 to rotate, a self-locking function can be achieved when the drive structure stops, preventing the first support 4 and the second support 5 from automatically rotating back, effectively improving the support effect.

[0048] In this embodiment, as Figure 1 As shown, the drive structure includes a motor 15 housed in the housing 1, a drive gear 16 mounted on the motor shaft, and a driven gear 17 mounted on the frame 6. The driven gear 17 is coaxially mounted with the output shaft 9, and the drive gear 16 meshes with the driven gear 17.

[0049] A switch for controlling the forward and reverse rotation of motor 15 is installed on the handlebars of the motorcycle. This switch is a time-delay switch. After the switch is pressed, motor 15 works for a period of time (e.g., 5 seconds) and then automatically stops. During the time that motor 15 works, the horizontally extended first bracket 4 / second bracket 5 can be swung down to contact the ground.

[0050] In order to achieve the purpose of retracting the first bracket 4 and the second bracket 5, the switch on the handle is a two-position switch, a forward switch and a reverse switch. When it is necessary to prop up the first bracket 4 and the second bracket 5, the motor 15 is reversed by controlling the two-position switch. Since the switch is a time delay switch, the motor 15 will automatically stop after a period of time, and the first bracket 4 and the second bracket 5 will be in the retracted state.

[0051] Example 2

[0052] like Figure 2 The motorcycle auxiliary support device shown includes a housing 1, a first rotating shaft 2 rotatably disposed within the housing 1, and a second rotating shaft 3 coaxially disposed with the first rotating shaft 2. The first rotating shaft 2 and the second rotating shaft 3 extend horizontally in the left-right direction. To facilitate better rotation, the first rotating shaft 2 and the second rotating shaft 3 can be rotatably mounted on the housing 1 via bearings.

[0053] like Figure 2 As shown, the first rotating shaft 2 is located on the left side of the housing 1. A first bracket 4 is located at the left end of the first rotating shaft 2, and a first support wheel is mounted on the first bracket 4. The axis of the first support wheel in its supported state is parallel to the axis of the motorcycle wheel. The second rotating shaft 3 is located on the right side of the housing 1, and a second bracket 5 is located at the right end of the second rotating shaft 3. A second support wheel is mounted on the second bracket 5, and its axis is parallel to the axis of the motorcycle wheel in its supported state. Rotation of the first rotating shaft 2 causes the first bracket 4 to swing, thereby supporting the first support wheel on the ground; rotation of the second rotating shaft 3 causes the second bracket 5 to swing, thereby supporting the second support wheel on the ground.

[0054] To provide support for motorcycles on surfaces with slopes or unevenness on both sides, such as... Figure 2 As shown, the first rotating shaft 2 and the second rotating shaft 3 are connected by a differential transmission structure located inside the housing 1. In order to enable the movement of the first support 4 and the second support 5, a drive structure for driving the differential structure is provided on the housing 1.

[0055] In use, the drive structure drives the differential structure to rotate, which in turn drives the first shaft 2 and the second shaft 3 to rotate. This causes the first bracket 4 and the second bracket 5 to swing downwards until their lower ends touch the ground, thus supporting the motorcycle.

[0056] When used on sloping roads or roads with different heights on the left and right, one of the brackets will contact the ground first. Due to the differential structure, the other bracket will also contact the ground under the action of the drive mechanism, so that both the first bracket 4 and the second bracket 5 are supported on the ground, thus supporting the motorcycle from two directions.

[0057] like Figure 2As shown, the differential structure includes a frame 6, two planetary gears 7 rotatably mounted on the frame 6, and two sun gears 8 meshing with the planetary gears 7 respectively. The two planetary gears 7 are coaxially arranged, and the two sun gears 8 are coaxially arranged and extend horizontally in the left-right direction. The center line of the planetary gears 7 is perpendicular to the center line of the sun gears 8. An output shaft 9 that rotatably engages with the housing 1 is coaxially fixed to the sun gear 8. The two output shafts 9 extend horizontally in the left-right direction. The frame 6 is rotatably mounted on the output shaft 9 located on the left side. The drive structure can drive the frame 6 to rotate around the output shaft 9. The first rotating shaft 2 is coaxially fixed to the output shaft 9 located on the left side, and the second rotating shaft 3 is coaxially fixed to the output shaft 9 located on the right side.

[0058] When the drive structure is working, it drives the frame 6 to rotate around the output shaft 9. Through the action of the planetary gear 7 and the sun gear 8, it drives the two output shafts 9 to rotate. The two output shafts 9 then drive the first rotating shaft 2 and the second rotating shaft 3 to rotate, thereby realizing the swing of the first bracket 4 and the second bracket 5. When encountering uneven road surfaces, one bracket will contact the ground first, and the other bracket will continue to swing downward under the action of the drive structure and the differential structure, and will also contact the ground.

[0059] like Figure 2 and Figure 4 As shown, both output shafts 9 are coaxially equipped with ratchet wheels 18. The housing 1 contains two pawls 19, each corresponding to one of the ratchet wheels 18. The pawls 19 engage with their respective ratchet wheels 18. The housing 1 is equipped with a ratchet unlocking mechanism 31 for unlocking. Under the action of a spring, the pawls 19 engage with the ratchet wheels 18, restricting their unidirectional rotation and allowing the output shafts 9 to rotate only in the direction that drives the first support 4 and the second support 5 to swing downwards. A pull cable is connected to the ratchet unlocking mechanism 31, with the outer end of the cable extending to the motorcycle's handlebars. When unlocking is required, pulling the cable disengages the pawls 19 from the ratchet wheels 18, releasing the output shafts 9 from their restraint.

[0060] In order to enable the first bracket 4 and the second bracket 5 to automatically reset, such as Figure 2 As shown, a return spring 30 is provided between the first bracket 4 and the housing 1, and a return spring 30 is also provided between the second bracket 5 and the housing 1. When the first bracket 4 and the second bracket 5 swing downwards, the return spring 30 is under tension. When reset is required, the ratchet 18 and pawl 19 are unlocked, and the first bracket 4 and the second bracket 5 can be reset under the action of the return spring 30. During the unlocking process, since the transmission structure is in a disconnected state, that is, the first gear 22 and the second gear 23 are disengaged from the transmission, the rotating sleeve 20 will not be driven to rotate.

[0061] like Figure 2As shown, the drive structure includes a rotating sleeve 20 rotatably disposed inside the housing 1 and rotatably sleeved on the output shaft 9 located on the left side, an intermediate shaft 21 rotatably disposed inside the housing 1 and parallel to the output shaft 9, a first gear 22 coaxially disposed on the rotating sleeve 20, a second gear 23 coaxially disposed on the intermediate shaft 21, a third gear 24 coaxially disposed on the intermediate shaft 21, and a fourth gear 25 disposed on the frame 6. The third gear 24 and the fourth gear 25 mesh. The rotating sleeve 20 is also provided with a foot pedal 26 located outside the housing 1. A torsion spring 27 is provided between the rotating sleeve 20 and the housing 1 for resetting the rotating sleeve 20. A transmission structure is provided between the first gear 22 and the second gear 23. When the foot pedal 26 swings downward, the transmission structure makes the first gear 22 and the second gear 23 drively connected.

[0062] When the first support 4 and the second support 5 need to be supported, step down on the foot pedal 26 to make the foot pedal 26 swing downward, thereby driving the rotating sleeve 20 to rotate in the same direction. At this time, the torsion spring 27 is pre-tightened and under the action of the transmission structure, the first gear 22 and the second gear 23 are connected to drive the intermediate shaft 21 to rotate. Through the third gear 24 and the fourth gear 25, the frame 6 is driven to rotate, thereby realizing the rotation of the two output shafts 9, which causes the first support 4 and the second support 5 to swing downward.

[0063] When the foot pedal 26 is released, the rotating sleeve 20 rotates in the opposite direction under the action of the torsion spring 27, thereby driving the first gear 22 to rotate in the opposite direction. Under the action of the first gear 22, the transmission structure is disengaged from the transmission, and the first gear 22 will not drive the second gear 23 to rotate, thus preventing the output shaft 9 from reversing. Together with the ratchet 18 and pawl 19, the first bracket 4 and the second bracket 5 are kept in the current support state.

[0064] like Figure 3 As shown, the housing 1 has two guide grooves 28 arranged opposite to each other. The transmission structure includes a transmission shaft and a transmission gear 29 coaxially mounted on the transmission shaft. The transmission shaft is parallel to the intermediate shaft 21. One end of the transmission shaft is slidably fitted in one of the guide grooves 28, and the other end of the transmission shaft is slidably fitted in the other guide groove 28. When the transmission shaft is located at the lower end of the guide groove 28, the transmission gear 29 only meshes with the first gear 22. When the foot pedal 26 is pressed down, the first gear 22 pushes the transmission gear 29, thereby moving the transmission shaft to the upper end of the guide groove 28. When the transmission shaft is located at the upper end of the guide groove 28, the transmission gear 29 meshes with the first gear 22 and the second gear 23 respectively.

[0065] Two guide grooves 28 are respectively provided on different sides of the housing 1. The width of the guide groove 28 is equal to the outer diameter of the drive shaft, so that the drive shaft can only slide up and down within the guide groove 28. To prevent axial movement of the drive shaft, an axial limit can be provided between the drive shaft and the housing 1.

[0066] When the drive shaft is located at the lower end of the guide groove 28, the drive gear 29 only meshes with the first gear 22. At this time, the drive gear 29 and the first gear 22 are deeply engaged. When the first gear 22 rotates under the action of the foot pedal 26, it can push the drive shaft to slide in the guide groove 28, thereby moving the drive shaft to the upper end of the guide groove 28. During this process, the drive gear 29 gradually meshes with the second gear 23, while not disengaging from the first gear 22. When the first gear 22 rotates, it will drive the second gear 23 to rotate through the drive gear 29, thereby realizing the swing of the first bracket 4 and the second bracket 5.

[0067] When the first gear 22 swings in the opposite direction, the transmission shaft slides from the upper end of the guide groove 28 to the lower end of the guide groove 28 under its own weight, and the transmission gear 29 disengages from the second gear 23.

[0068] like Figure 3 As shown, the first gear 22 has more teeth than the transmission gear 29, the transmission gear 29 has more teeth than the second gear 23, and the third gear 24 and the fourth gear 25 have similar numbers of teeth. Due to the large gear ratio, the output shaft 9 can rotate a large angle when the foot pedal rotates a small angle.

[0069] Example 3

[0070] like Figure 5 The motorcycle auxiliary support device shown includes a housing (not shown in the figure), a first rotating shaft 2 rotatably disposed in the housing, and a second rotating shaft 3 coaxially disposed with the first rotating shaft 2. The first rotating shaft 2 and the second rotating shaft 3 extend horizontally in the left-right direction. A first bracket 4 is provided at the right end of the first rotating shaft 2 extending out of the housing, and a second bracket 5 is provided at the left end of the second rotating shaft 3 extending out of the housing. Support wheels are respectively provided on the first bracket 4 and the second bracket 5. The first rotating shaft 2 and the second rotating shaft 3 are connected by a differential structure disposed in the housing. The housing is provided with a drive structure for driving the differential structure.

[0071] The driving structure in this embodiment is the same as the driving structure in Embodiment 1.

[0072] like Figure 5 As shown, the differential structure includes a frame 6, two planetary gears 7 rotatably mounted on the frame 6, and two sun gears 8 meshing with the planetary gears 7 respectively. The two planetary gears 7 are coaxially arranged, and the two sun gears 8 are coaxially arranged. The center line of the planetary gears 7 is perpendicular to the center line of the sun gears 8. An output shaft 9 that rotates and engages with the housing is coaxially fixed to the sun gear 8. The output shaft 9 extends horizontally in the left-right direction. The frame 6 is rotatably mounted on one of the output shafts 9. The drive structure drives the frame 6 to rotate around the output shaft 9. The first rotating shaft 2 is connected to the output shaft 9 located on the right side, and the second rotating shaft 3 is connected to the output shaft 9 located on the left side.

[0073] like Figure 5 As shown, each output shaft 9 is coaxially equipped with a first bevel gear 12. The housing is also rotatably equipped with a horizontally extending intermediate shaft 21. There are two intermediate shafts 21. A second bevel gear 13 is coaxially equipped at one end of the intermediate shaft 21. The first bevel gear 12 and the opposite second bevel gear 13 mesh. A worm gear 10 is coaxially equipped on the intermediate shaft 21. A worm wheel 11 is coaxially equipped on both the first rotating shaft 2 and the second rotating shaft 3. The worm wheel 11 on the right side meshes with the worm gear 10 on the right intermediate shaft 21, and the worm wheel 11 on the left side meshes with the worm gear 10 on the left intermediate shaft 21.

[0074] When the drive structure is working, it drives the two first bevel gears 12 to rotate in the same direction, thereby driving the two second bevel gears 13 to rotate in the same direction, which in turn drives the two worm gears 10, which are respectively mounted on different intermediate shafts 21, to rotate. The two worm gears 10 drive the two different worm wheels 11 to rotate, thereby realizing the rotation of the first rotating shaft 2 and the second rotating shaft 3 in the same direction, and finally achieving the purpose of making the first support 4 and the second support 5 swing in the same direction.

[0075] Since the worm gear 10 drives the worm wheel 11 to rotate, a self-locking function can be achieved when the drive structure stops, preventing the first support 4 and the second support 5 from rotating automatically, thus effectively improving the support effect.

[0076] A switch for controlling the forward and reverse rotation of motor 15 is installed on the handlebars of the motorcycle. This switch is a time-delay switch. After the switch is pressed, motor 15 works for a period of time (e.g., 5 seconds) and then automatically stops. During the time that motor 15 works, the horizontally extended first bracket 4 / second bracket 5 can be swung down to contact the ground.

[0077] In order to achieve the purpose of retracting the first bracket 4 and the second bracket 5, the switch on the handle is a two-position switch, a forward switch and a reverse switch. When it is necessary to prop up the first bracket 4 and the second bracket 5, the motor 15 is reversed by controlling the two-position switch. Since the switch is a time delay switch, the motor 15 will automatically stop after a period of time, and the first bracket 4 and the second bracket 5 will be in the retracted state.

[0078] Example 4

[0079] like Figure 6 The motorcycle auxiliary support device shown includes a housing (not shown in the figure), a first rotating shaft 2 rotatably disposed in the housing, and a second rotating shaft 3 coaxially disposed with the first rotating shaft 2. The first rotating shaft 2 and the second rotating shaft 3 extend horizontally in the left-right direction. A first bracket 4 is provided at the right end of the first rotating shaft 2 extending out of the housing, and a second bracket 5 is provided at the left end of the second rotating shaft 3 extending out of the housing. Support wheels are respectively provided on the first bracket 4 and the second bracket 5. The first rotating shaft 2 and the second rotating shaft 3 are connected by a differential structure disposed in the housing. The housing is provided with a drive structure for driving the differential structure.

[0080] The driving structure in this embodiment is the same as the driving structure in Embodiment 1.

[0081] like Figure 6 As shown, the differential structure includes a frame 6, two planetary gears 7 rotatably mounted on the frame 6, and two sun gears 8 meshing with the planetary gears 7 respectively. The two planetary gears 7 are coaxially arranged, and the two sun gears 8 are coaxially arranged. The center line of the planetary gears 7 is perpendicular to the center line of the sun gears 8. An output shaft 9 that rotates and engages with the housing is coaxially fixed to the sun gear 8. The output shaft 9 extends horizontally in the left-right direction. The frame 6 is rotatably mounted on one of the output shafts 9. The drive structure drives the frame 6 to rotate around the output shaft 9. The first rotating shaft 2 is connected to the output shaft 9 located on the right side, and the second rotating shaft 3 is connected to the output shaft 9 located on the left side.

[0082] like Figure 6 As shown, each output shaft 9 is coaxially provided with a first worm gear 101. The housing is also rotatably provided with a horizontally extending intermediate shaft 21. There are two intermediate shafts 21. A first worm wheel 111 is coaxially provided on the intermediate shaft 21. The first worm gear 101 and the corresponding first worm wheel 111 mesh. A second worm gear 102 is coaxially provided on the intermediate shaft 21. A second worm wheel 112 is coaxially provided on both the first rotating shaft 2 and the second rotating shaft 3. The second worm wheel 112 on the right side meshes with the second worm gear 102 on the right intermediate shaft 21, and the second worm wheel 112 on the left side meshes with the second worm gear 102 on the left intermediate shaft 21.

[0083] When the drive structure is working, it drives the two output shafts 9 to rotate in the same direction, thereby driving the two first worm gears 101 to rotate in the same direction, and then driving the two first worm wheels 111, which are respectively set on different intermediate shafts 21, to rotate, so that the two intermediate shafts 21 rotate in the same direction, thereby driving the two second worm gears 102 to rotate in the same direction. Through the action of the second worm wheels 112, the first rotating shaft 2 and the second rotating shaft 3 will be driven to rotate in the same direction, ultimately achieving the purpose of making the first support 4 and the second support 5 swing in the same direction.

[0084] By using a worm gear to drive a worm wheel, a self-locking function can be achieved when the drive structure stops, preventing the first bracket 4 and the second bracket 5 from rotating automatically, thus effectively improving the support effect.

[0085] A switch for controlling the forward and reverse rotation of motor 15 is installed on the handlebars of the motorcycle. This switch is a time-delay switch. After the switch is pressed, motor 15 works for a period of time (e.g., 5 seconds) and then automatically stops. During the time that motor 15 works, the horizontally extended first bracket 4 / second bracket 5 can be swung down to contact the ground.

[0086] In order to achieve the purpose of retracting the first bracket 4 and the second bracket 5, the switch on the handle is a two-position switch, a forward switch and a reverse switch. When it is necessary to prop up the first bracket 4 and the second bracket 5, the motor 15 is reversed by controlling the two-position switch. Since the switch is a time delay switch, the motor 15 will automatically stop after a period of time, and the first bracket 4 and the second bracket 5 will be in the retracted state.
