[0002] Motorcycles are common means of transportation in daily life, widely used for patrolling, passenger and cargo transportation, etc., and also used as sports equipment. Generally speaking, motorcycles are divided into street motorcycles, road racing motorcycles, off-road motorcycles, cruisers, touring motorcycles, etc. Conventional motorcycle parking brackets are divided into side brackets and large brackets. Motorcycles can only be parked by tilting to one side through the side bracket. The side bracket is subject to great force. When parking with a large bracket, it takes a lot of effort to support the motorcycle. People with less strength cannot easily park a motorcycle with a large bracket.

[0003] When parking a conventional motorcycle, the driver of the motorcycle actively uses his feet to retract or extend the side stand to ensure that the motorcycle is parked stably. A common side stand retracting and extending mechanism of a motorcycle utilizes a tension spring to manipulate the side support rod, and cooperates with the upper and lower stop points for limiting the position. During the process of retracting or extending the side stand, the movements are cumbersome, and the legs are easily interfered with components such as pedals.

[0004] Therefore, there is an urgent need to develop a motorcycle side stand that can save the driver from the cumbersome task of retracting and extending the side stand with his feet, reduce the driver's left foot movements when parking, and improve the convenience and comfort of the driving experience.

[0023] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0024] Figure 1 It is a structural schematic diagram of the utility model. Figure 2 This is a schematic diagram of the side bracket of the utility model in a folded state. Figure 3 This is a schematic diagram of the side bracket of the utility model in an open state, as shown in FIG. Figure 1 As shown, the electric drive side bracket assembly for a motorcycle of the utility model comprises:

[0025] A side stand 4, which can be driven to open to support the motorcycle or can be driven to be folded;

[0026] The driving assembly is mounted on the motorcycle frame and has a power output end, and the power output end is used to drive the side bracket 4 to open or retract.

[0027] In this embodiment, it also includes a shell, which is fixed to the frame; the driving assembly includes a power source and a transmission assembly, the transmission assembly is accommodated in the shell and includes the power output end, and the power source is installed on the frame through the shell; after the driving assembly drives the transmission assembly to rotate, the side bracket 4 can rotate relative to the frame to achieve support for the frame.

[0028] In this embodiment, the shell is provided with a clearance groove, and the clearance groove provides a swing space for the side bracket to be opened or retracted; Figure 1As shown, the shell can be manufactured by snap-fitting or by integrally molding with a mold, which will not be elaborated here. However, considering the replacement of the side bracket 4 and the adaptability of different models of side brackets 4, the shell is manufactured by snap-fitting so that the side bracket 4 can be replaced more easily, making the present solution more adaptable to different models of side brackets 4 required for different models of motorcycles.

[0029] In this embodiment, the transmission assembly includes a worm wheel 6 and a worm 10 that cooperates with the worm wheel 6. The power source is used to drive the worm 10 to rotate, and the worm wheel 6 serves as the power output end to drive the side bracket 4 to open or retract. Because the worm 10 and the worm wheel 6 have a self-locking function, that is, the worm 10 can drive the worm wheel to rotate, but the worm wheel 6 cannot drive the worm 10 to rotate, it is only necessary to stop the driving assembly from outputting power to the worm 10, and the side bracket position will be locked.

[0030] In this embodiment, the shell is formed by snapping together a half shell I3 and a half shell II7, and one end of the side bracket 4 extends into the shell through a clearance groove 14 to cooperate with the worm gear 6, so that the side bracket 4 can be driven to swing along the front and rear directions; a plurality of bolt holes 16 matching the shell bolts 1 are provided on the half shell I3 and the half shell II7. When the half shell I3 and the half shell II7 are snapped together, the shell bolts 1 are screwed into the bolt holes 16 of the half shell I3 and the half shell II7 for fixing. When the side bracket 4, the worm gear 6 and the worm 10 need to be repaired and replaced, the half shell I3 and the half shell II7 can be disassembled after the shell bolts 1 are screwed out of the bolt holes 16, which is convenient for repair and replacement.

[0031] The clearance groove 14 is a strip groove arranged along the length direction of the frame. The half shell I3 and the half shell II7 respectively open half of the groove at the position corresponding to the clearance groove 14, so that after the half shell I3 and the half shell II7 are buckled together, the half of the groove on the half shell I3 and the half shell II7 are buckled together to form the clearance groove 14. Figure 4 As shown, after the half shell I3 and the half shell II7 are buckled together, two limiting surfaces are formed, namely, limiting surface I for limiting when the side bracket 4 is opened and limiting surface II for limiting when the side bracket 4 is folded.

[0032] The side bracket 4 can be driven to swing in the front-to-back direction, and the front-to-back direction refers to the side bracket 4 extending into the give way slot 14 and swinging back and forth along the length direction of the frame. During the process of opening or retracting the side bracket 4, the area through which the side bracket 4 swings is the swing range of the side bracket 4, and the swing range has two directional limits, one of which corresponds to the retracted state of the side bracket 4, and the other corresponds to the opened state of the side bracket 4; when the side bracket 4 is in the retracted state, the corresponding directional limit is horizontal, horizontally upward or downward, which can ensure that the side bracket 4 is detached from the ground and ends support when retracted.

[0033] In this embodiment, the power source is a drive motor 9, which is installed outside the shell, and its rotor shaft extends into the shell and is coaxially matched with the worm 10; the drive motor 8 is installed on the frame through the shell. Since the rotor shaft of the drive motor 10 extends into the shell and is coaxially matched with the worm 10, and the worm 10 and the worm wheel 6 are matched to drive the side bracket 4 to open or retract, the transmission assembly can be installed on the frame through the drive motor 9 and the shell.

[0034] In this embodiment, one end of the side bracket 4 is a driving part 13, and the other end is a supporting part 12. The driving part 13 is provided with an axial hole 17, and the axial hole 17 and the worm wheel 6 are inserted into a rotating shaft 2, which is used for the coaxial transmission of the side bracket 4 and the worm wheel 6. A locking pin 5 for locking the driving part 13 and the worm wheel 6 is inserted between the driving part 13 and the worm wheel 6, and the locking pin 5 deviates from the axis of the rotating shaft 2; the half shell Ⅰ3 and the half shell Ⅱ7 are both provided with circular holes corresponding to the rotating shaft 2, and the rotating shaft 2 is provided with a terminal at one end. The diameter of the end is larger than the circular hole, and a thread is provided at the other end. After the half-shell I3 and the half-shell II7 are buckled together to form a shell, the circular hole is coaxial with the axial hole 17 of the drive part 13 and the worm gear 6. The threaded end of the rotating shaft 2 is inserted into the circular hole on the half-shell I3 and passes through the axial hole 17 of the drive part 13 and the worm gear in turn, and then passes out of the circular hole on the half-shell II7. After the end of the rotating shaft 2 abuts against the half-shell I3, the protruding threaded section is installed by screwing the nut 8 until the nut 8 abuts against the half-shell II7.

[0035] In this embodiment, the driving part 13 is provided with a bayonet, and the bayonet forms a load-bearing platform 11. The load-bearing platform 11 is in contact with the edge of the worm gear 15, and is used to cooperate with the support part 12 to bear the load when the side bracket 4 is opened; since the side bracket 4 is subjected to large force during the supporting process, relying solely on the support part 12 of the side bracket 4 to support the vehicle body can easily damage the side bracket 4 and shorten its service life. When the side bracket 4 is opened for support, the load-bearing platform 11 arranged on the driving part 13 and in contact with the edge of the worm gear 6 can assist the support part 12 of the side bracket 4 in supporting the weight of the vehicle body.

[0036] In this embodiment, the contour of the worm wheel 6 is fan-shaped, and the center angle of the fan is the same as the center angle of the side bracket 4 rotating around the rotating shaft 2 in the make way groove 14; by setting the same center angle, it can be ensured that the rotation of the worm wheel 6 and the rotation of the side bracket 4 in the make way groove 14 are in the same amplitude.

[0037] In this embodiment, a motorcycle is further provided, characterized in that: the motorcycle is equipped with the above-mentioned electric drive side bracket assembly for a motorcycle, and the usage of this embodiment is as follows:

[0038] The housing is fixed to the vehicle frame, and the worm wheel 6 and the worm 10 are accommodated inside the housing. The rotor shaft of the drive motor 9 extends into the housing and is coaxially matched with the worm 10, so that the drive motor 9 can be installed on the vehicle frame through the housing.

[0039] The worm wheel 6 is connected to the driving part 13 of the side bracket 4 through the rotating shaft 2. A locking pin 5 for locking the driving part and the worm wheel 6 is provided between the driving part 13 and the worm wheel 6 and deviates from the axis of the rotating shaft 2 to prevent the worm wheel 6 and the side bracket 4 from rotating relative to each other.

[0040] like Figure 2 As shown, the side bracket 4 is in the retracted state. When the side bracket 4 needs to be opened to support the vehicle body, the drive motor 9 is energized, the rotor shaft of the drive motor 9 rotates to drive the worm 10 to rotate, the worm 10 drives the worm wheel 6 to rotate, and the worm wheel 6 drives the side bracket 4 to rotate in the clearance groove 14 through the rotating shaft 2 coaxially, as shown in FIG. Figure 4 As shown, when the side bracket 4 is rotated to a position where it can be supported and used, the driving part 13 of the side bracket 4 is blocked by the limit surface I, and the side bracket 4 no longer rotates, and the drive motor 9 is blocked, triggering a power-off stop. At this time, the drive motor 9 stops outputting power to the worm 10, and the worm wheel 6 and the worm 10 are self-locking to lock the position of the side bracket 4; similarly, when the side bracket 4 needs to be folded up, the drive motor 9 is energized in the reverse direction, which produces the same effect as the forward energization, and the side bracket 4 returns to the folded state. The worm wheel 6 is blocked by the limit surface II, and the side bracket 4 no longer rotates and is locked.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
