Description

Technical Field

[0001] This application relates to the field of hoverboard technology, and in particular to a drive wheel assembly for a hoverboard. Background Technology

[0002] A scooter is a children's toy car that moves by turning a steering wheel left and right. Currently available on the market are electric scooters with a motor installed on the front wheel for additional power, and a battery installed inside the vehicle to drive the motor. The front wheel of this type of scooter serves as both the drive wheel and the steering wheel. Therefore, when children use it, the excessive number of rotations of the front wheel caused by the steering wheel can lead to the wires connecting the drive motor and the battery becoming tangled and twisted, potentially resulting in a power outage or short circuit. Utility Model Content

[0003] This application provides a drive wheel assembly for a scooter, which at least solves the technical problem in the related art that the front wheel of an electric scooter cannot rotate freely due to the restriction of the wire.

[0004] To achieve the above objectives, this application provides a drive wheel assembly for a scooter, including a base, a drive wheel disposed outside the base, a drive motor disposed inside the base and pulsatorically connected to the drive wheel, a connecting part disposed on the upper part of the base, the connecting part being provided with a slip ring and a rotatable sleeve, the drive motor being electrically connected to the slip ring via a wire, and the sleeve being provided with a brush rotatable around the slip ring, one end of the brush abutting against the slip ring and the other end being electrically connected to a power source.

[0005] In some embodiments, the connecting portion protrudes relative to the base, and the sleeve is rotatably fitted over the connecting portion.

[0006] In some embodiments, the slip ring is fitted onto the connecting portion.

[0007] In some embodiments, the wires, slip rings, and brushes are provided in two sets and are respectively connected to the positive and negative terminals of the drive motor.

[0008] In some embodiments, the slip rings are axially spaced and fitted onto the connecting portion.

[0009] In some embodiments, the brush is disposed between the slip ring and the sleeve.

[0010] In some embodiments, the brush is fixedly connected to the sleeve and can rotate with the sleeve.

[0011] In some embodiments, the brush includes a brush head that abuts against the slip ring and a brush rod that extends along the axial direction of the sleeve.

[0012] In some embodiments, the brush head has an arc-shaped structure that protrudes toward the slip ring and abuts against the slip ring.

[0013] In some embodiments, two drive wheels and one driven wheel are disposed outside the base.

[0014] Based on the above, the beneficial effects of the technical solution of this application are: a slip ring connected to the positive and negative poles of the motor is provided on the base, and an electric brush that abuts and is energized is provided outside the slip ring. The electric brush can rotate freely around the slip ring and is not bound by the wire. Attached Figure Description

[0024] This application provides a drive wheel assembly for a scooter, including a base, a drive wheel disposed outside the base, a drive motor disposed inside the base and connected to the drive wheel, a connecting part disposed on the upper part of the base, the connecting part being provided with a slip ring and a rotatable sleeve, the drive motor being electrically connected to the slip ring via a wire, and the sleeve being provided with a brush that can rotate around the slip ring, one end of the brush abutting against the slip ring and the other end being electrically connected to a power source.

[0025] Implementation, for example Figures 1-4As shown, a drive wheel assembly for a scooter includes a base 1, a drive motor 2 housed within the base 1, and two drive wheels 3, which are driven and connected to the drive motor 2, and a driven wheel 4, which moves only with the drive wheels 3 and is not driven and connected to the drive motor 2, located outside the base 1. A protruding connecting portion 1.1 is provided on the upper part of the base 1. Two slip rings 1.2, spaced apart along the axial direction, are fitted onto the connecting portion 1.1. The positive and negative terminals of the drive motor 2 are electrically connected to a slip ring 1.2 via wires 5, and the two slip rings 1.2 do not contact each other. A rotatable sleeve 6 is fitted over the connecting portion 1.1. Inside the sleeve 6 are two brushes 7, which are respectively connected to the positive and negative terminals of the scooter's power supply. The two brushes 7 respectively engage with a slip ring 1.2 and can rotate around the slip ring 1.2 while abutting against it.

[0026] Specifically, the wire 5, slip ring 1.2, and brush 7 are each provided in two sets. In one set, one end of the wire 5 is connected to the positive terminal of the drive motor 2, and the other end passes through the connecting part 1.1 to connect to a slip ring 1.2. One end of the brush 7 abuts against the slip ring 1.2, and the other end is electrically connected to the positive terminal of the power supply. In the other set, one end of the wire 5 is connected to the negative terminal of the drive motor 2, and the other end passes through the connecting part 1.1 to connect to a slip ring 1.2. One end of the brush 7 abuts against the slip ring 1.2, and the other end is electrically connected to the negative terminal of the power supply. After the power is turned on, the drive motor 2 can remain energized regardless of the rotation between the sleeve 6 and the base 1, and the rotation range is not restricted by the wire 5.

[0027] Furthermore, the brush 7 is fixedly connected to the sleeve 6 and can rotate around the slip ring 1.2 following the sleeve 6. The brush 7 includes a brush head 7.1 that abuts against the slip ring 1.2 and a brush rod 7.2 that extends along the axial direction of the sleeve 6. The brush head 7.1 is disposed between the slip ring 1.2 and the sleeve 6.

[0028] Specifically, the brush head 7.1 has an arc-shaped structure that protrudes towards the slip ring 1.2 and abuts against the slip ring 1.2. The arc-shaped structure reduces friction when the brush head 7.1 abuts against the slip ring 1.2 and rotates around the slip ring 1.2.

[0029] In another embodiment (not shown in the figure), the connecting part 1.1 may also be recessed towards the inside of the base 1, the sleeve 6 is rotatably inserted into the connecting part 1.1, the slip ring 1.2 is disposed on the inner wall of the connecting part 1.1, and the brush 7 is disposed on the outside of the sleeve 6, so that the brush 7 can abut against the slip ring 1.2 and move around the slip ring 1.2.

[0030] Those skilled in the art should understand that the technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
