[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] like Figures 1-6 As shown, this solution provides a reversing auxiliary wheel device for motorcycles, including auxiliary wheel arms 1 symmetrically arranged on both sides of the rear wheel. The auxiliary wheel arms 1 are provided with an arm rotating part 101 and an auxiliary wheel mounting part 102. The auxiliary wheel mounting part 102 is provided with a hub motor wheel 2.

[0034] The outrigger rotating part 101 is movably mounted on the flat fork mounting part 3 and is driven by the drive assembly 5 to rotate clockwise or counterclockwise with the outrigger rotating part 101 as the center, thereby driving the hub motor wheel 2 to contact or detach from the ground.

[0035] The drive assembly 5 and the hub motor wheel 2 are connected to the electronic control module.

[0036] In this embodiment, the flat fork mounting component 3 is used to facilitate fixing with the left and right connecting arms of the motorcycle's rear flat fork, thereby enabling easy connection of this reversing auxiliary wheel device to the motorcycle. This provides safety assistance during low-speed motorcycle driving, and when the motorcycle needs to reverse, the drive components 5 on both sides drive the auxiliary wheel support arm 1 to rotate clockwise, bringing the hub motor wheel 2 into contact with the ground. Then, the electronic control module controls the hub motor wheel 2 to rotate clockwise, thereby driving the motorcycle to reverse.

[0037] It should be noted that the electronic control module described in this embodiment can be a control circuit independent of the motorcycle, or it can be a circuit integrated with the motorcycle circuit. Since these two circuit configuration methods are well known in the art, this embodiment will not further describe the specific structure of the circuit.

[0038] The hub motor wheel 2 used in this embodiment is an integrated wheel that installs the motor in the hub of the wheel and directly drives the wheel to rotate. Its working principle is based on electromagnetic induction. The motor has a stator and a rotor inside. The stator generates a magnetic field after being powered, which interacts with the rotor magnetic field to generate an electromagnetic torque, thereby driving the wheel to rotate. This design eliminates the complex transmission components such as clutches, transmissions, and drive shafts in traditional vehicles, making the vehicle structure simpler and reducing the weight and cost of the vehicle.

[0039] The auxiliary wheel mounting portion 102 is provided at the lower end of the auxiliary wheel arm 1 and connects the hub motor wheel 2 through a pin shaft 7.

[0040] As shown in Figures 1-3 , the flat fork mounting member 3 is provided with a driving assembly mounting position 301 and a rotating shaft mounting position 302. The driving assembly 5 is installed on the driving assembly mounting position 301. The auxiliary wheel arm 1 is hinged to the rotating shaft mounting position 302 through the arm rotating portion 101 and the arm rotating shaft 4.

[0041] This structure can compactly mount the driving assembly 5 and the auxiliary wheel arm 1 on the flat fork mounting member 3, and can better facilitate the installation and connection of the reverse auxiliary wheel device with the motorcycle.

[0042] The auxiliary wheel arm in this embodiment includes two forms, as follows:

[0043] As shown in Figure 1 , Figure 5 and Figure 6 , the first type is that the auxiliary wheel arm 1 is a straight arm.

[0044] As shown in Figures 2-4 , the second type is that the auxiliary wheel arm 1 is a foldable arm, which includes a first arm 103 and a second arm 104 that can be hinged to each other. The first arm 103 is provided with the arm rotating portion 101. The second arm 104 is provided with the auxiliary wheel mounting portion 102.

[0045] It also includes a pull rod 105. One end of the pull rod 105 is movably connected to the flat fork mounting member 3, and the other end is movably connected to the hinge between the first arm 103 and the second arm 104.

[0046] Under the action of the pull rod, the folding direction and folding angle of the first arm 103 and the second arm 104 can be better limited, thereby ensuring the precise folding between the first arm 103 and the second arm 104. This folding structure can better support the hub motor wheel 2, so that it can better withstand the force applied by the motorcycle.

[0047] As Figure 7 shown in the embodiment, the driving assembly 5 comprises a motor 501 and a worm gear reduction module 502 connected with each other, the worm gear reduction module 502 comprises a worm gear housing 503, a worm gear shaft 504 movably arranged in the worm gear housing 503, and a toothed rod gear 505 sleeved on the worm gear shaft 504;

[0048] A pair of windows 506 are formed on the worm gear housing 503, and a transmission toothed rod 508 can pass through the windows 506, and the transmission toothed rod 508 is engaged with the toothed rod gear 505.

[0049] A worm 507 is connected to the rotating shaft end of the motor 501, and the worm 507 is engaged with the worm gear shaft 504.

[0050] Through the above driving assembly, not only the occupied space is small, but also the accurate driving of the auxiliary wheel support arm can be realized.

[0051] The transmission toothed rod 508 is L-shaped, comprising a toothed rod support arm 510 having a toothed rod rotating part 509, and an arc-shaped toothed rod 512 having a tooth path 511 arranged on the inner side thereof.

[0052] The toothed rod rotating part 509 is connected with the support arm rotating part 101 through a connecting screw 6, and the tooth path 511 of the arc-shaped toothed rod 512 is engaged with the toothed rod gear 505.

[0053] After receiving the instruction of the electric control module, the motor 501 drives the toothed rod gear 505 to rotate, and then drives the transmission toothed rod 508 to rotate counterclockwise or clockwise with the toothed rod rotating part 509 as the rotating center, since the transmission toothed rod 508 is fixedly connected with the auxiliary wheel support arm 1, the auxiliary wheel support arm 1 can be driven to rotate clockwise or counterclockwise with the support arm rotating part 101 as the center, so that the hub motor wheel 2 is brought into contact with or separated from the ground.

[0054] The above only describes the embodiments of the utility model, and is not used for limiting the utility model, for the person skilled in the art, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
