The term appearing in various places in the specification are not necessarily as shown in the same embodiment, and are not exclusive or alternative embodiments that are mutually exclusive with other embodiments. Those skilled in the art will understand explicitly and implicitly that the embodiments described herein may be combined with other embodiments.

FIG. 1 is a stereogram of a rotating wheel according to some embodiments of the present disclosure, and FIG. 2 is an exploded view of the rotating wheel shown in FIG. I. As shown in FIGS. 1-2, in some embodiments, a rotating wheel 100 may be provided. The rotating wheel 100 may include a motor 10 and an audio unit 20. The motor 10 may include a stator 12, a rotor 14, and a motor shaft 40. In some embodiments, the motor shaft 40 may pass through the stator 12. In some embodiments, a through hole may be defined at a center of the stator 12, and the motor shaft 40 may pass through the through hole and be further inserted into the rotor 14. With reference to FIG. 4, a motor hole 42 passing through the motor shaft 40 may be defined in the motor shaft 40. The motor hole 42 may be configured to receive or accommodate a power wire 91 and an audio wire 92. The rotor 14 may be sleeved on a periphery of the stator 12, and may be rotatable relative to the stator 12. The audio unit 20 may be arranged on or even fixed on the motor shaft 40, and may be electrically connected to the power wire 91 and the audio wire 92. In this way, the audio unit 20 may be able to play music.

In some embodiments, the acoustic unit 20 may be disposed at one end of the motor shaft 40 and outside the motor shaft 40. The power wire 91 and the audio wire 92 may pass through the motor hole and may be further electrically connected to the acoustic unit 20.

More specifically, in some embodiments of the present disclosure, a power source and an audio source may be arranged outside the rotating wheel 100. One end of the power wire 91 may be electrically connected to the power source, and one end of the audio wire 92 may be electrically connected to the audio source. The other end of the power wire 91 and the other end of the audio wire 92 may each pass through the motor hole 42, extend out of the motor hole 42, and be further electrically connected to the audio unit 20. In this way, it is possible to supply power to the audio unit 20, and the audio unit 20 may produce a sound. By arranging the power wire 91 and the audio wire 92 in the motor hole 42, on one hand, the motor shaft 40 may provide a shielding to the power wire 91 and the audio wire 92 to reduce the possibility of damage to the power wire 91 and the audio wire 92 due to the exposure of the power wire 91 and the audio wire 92, and further reduce the possibility of affecting an appearance of the product. On the other hand, it may also possible to fully utilize the space inside the motor shaft 40 to make the structure of the rotating wheel 100 more compact. Furthermore, by arranging the power source and the audio source outside the rotating wheel, a volume of the rotating wheel 100 may be reduced.

In some embodiments, a mounting hole may be further defined in the center of the audio unit 20. The motor shaft 40 may be inserted in the mounting hole by an interference fit, such that the audio unit 20 may be fixed on the motor shaft 40. In this way, the mounting of the audio unit 20 may be simplified.

FIG. 3 is an exploded view of the acoustic unit 20 shown in FIG. 2, and FIG. 4 is a stereogram of the motor shaft 40 shown in FIG. 2, In some embodiments, as shown in FIG, 2 to FIG. 4, a first assembly hole 21 may be defined in the audio unit 20, and a second assembly hole 41 may be defined in the motor shall 40. A fastener such as a screw or the like may pass through the second assembly hole 21 and be further connected to (for example, inserted into) the second assembly hole 41. In this way, the audio unit 20 may be fixedly mounted at an end portion of the motor shaft 40. Or, in some embodiments, the motor shaft 40 and the audio unit 20 may also be fixedly connected to each other by, for example, bonding, which may be not specifically limited in the present disclosure.

Furthermore, as shown in FIG. 3, the audio unit 20 may include a rear shell 22, a front shell 23, a speaker 24, and a resonance unit 25. The rear shell 22 may be buckled with or engaged with the front shell 23 to form a receiving cavity 20a. The speaker 24 and the resonance unit 25 may be arranged or received in the receiving cavity 20a, and may be spaced apart from each other.

More specifically, one side of the rear shell 22 that is adjacent to the front shell 23 defines a first recess, and one side of the front shell 23 that is adjacent to the rear shell 22 defines a second recess, When the rear shell 22 is engaged with the front shell 23, the first recess and the second recess will cooperatively form or enclose or define the receiving cavity 20a configured to receive the speaker 24 and the resonance unit 25.

In some embodiments, it is possible to arrange a hook on one of the rear shell 22 and the front shell 23, and arrange a buckle on the other of the rear shell 22 and the front shell 23, and the rear shell 22 may be engaged with or buckled with the front shell 23 via the hook and the buckle. In some embodiments, each of the rear shell 22 and the front shell 23 may define an assembly hole, and the rear shell 22 and the front shell 23 may be fixedly connected to each other through the assembly holes defined in the rear shell 22 and the front shell 23 by using fasteners such as screws. In some embodiments, the rear shell 22 and the front shell 23 may also be connected to each other via threaded structures cooperating with each other, By connecting the rear shell 22 to the front shell 23 in a detachable manner, the mounting and maintenance of the audio unit 20 may be facilitated. By disposing the speaker 24 and the resonance unit 25 in the receiving cavity 20a, the structure of the audio unit 20 may be more compact. In this way, on one hand, the mounting of the audio unit 20 may be facilitated; on the other hand, the structure of the audio unit 20 may be compact, thereby reducing space occupied by the audio unit 20 in the rotating wheel 100. Thus, it is possible to realize the miniaturized design of the rotating wheel 100.

In addition, as shown in FIG. 3, the front shell 23 may define a first opening 232a at a position corresponding to the speaker 24, and further define a second opening 232b at a position corresponding to the resonance unit 25. The speaker 24 and the resonance unit 25 may be sandwiched between the front shell 23 and the rear shell 22. Furthermore, a sound output surface 24a of the speaker 24 may be arranged corresponding to the first opening 232a, and a sound output surface 25a of the resonance unit 25 may be arranged corresponding to the second opening 232b. Thus, by defining the first opening 232a in the front shell 23 at a position corresponding to the speaker 24 and the second opening 232b in the front shell 23 at a position corresponding to the resonance unit 25, it is possible to provide a clearance to the speaker 24 and the resonance unit 25. In this way, it is possible to reduce the possibility of reducing a volume due to the blocking of the sound from the speaker and the resonance unit 25 by the front shell 23.

In some embodiments of the present disclosure, the speaker 24 and the resonance unit 25 may be separately disposed at two sides of the front shell 23, and the speaker 24 and the resonance unit 25 may be spaced apart from each other. In this way, it is possible to reduce the possibility of reducing the structural strength of the front shell 23 due to the defining of the first opening 232a and the second opening 232b, the speaker 24 and the resonance unit 25 may produce sounds evenly, and the sound effect may be improved.

In some embodiments, as shown in FIGS. 3-4, the rear shell 22 is disposed at one side of the audio unit 20 that is adjacent to the motor shaft 40, that is, the rear shell 22 is disposed closer to the motor shaft 40 than the front shell 23. The connection between the motor shaft 40 and the audio unit 20 may be actually achieved by the connection between the motor shaft 40 and the rear shell 22 of the audio unit 20. The rear shell 22 may define a wire hole 222 corresponding to the motor hole 42. When the motor shaft 40 is connected to the rear shell 22, the motor hole 42 will be aligned with the wire hole 222. The power wire 91 and the audio wire 92 may pass through the motor hole 42 and the wire hole 222 and may be electrically connected to the speaker 24 and the resonance unit 25.

In some embodiments, as shown in FIG. 2, the rotating wheel 100 may further include a lighting unit 30. The lighting unit 30 may be arranged on the rotor 14 and electrically connected to the power source to emit light. The lighting unit 30 may be rotatable when driven by the rotor 14. On one hand, the lighting unit 30 may be configured for illumination. On the other hand, the lighting unit 30 may be further configured to form a cooling lighting effect to improve the visual appearance of the rotating wheel 100. In this way, the rotating wheel 100 in some embodiments of the present disclosure may integrate multiple functions, such that the functions of the rotating wheel 100 may be more diverse, and the user experience may be improved.

FIG. 5 is a stereogram of the rotor 14 shown in FIG. 2, and FIG. 6 is a cross-sectional view of the rotor 14 shown in FIG. 5. As further shown in FIGS. 5 and 6, the rotor 14 may include a rotating member 142 and a positioning plate 144 disposed in the rotating member 142. The rotating member 142 may be in shape of a barrel and implemented as a roller. The positioning plate 144 may be connected to an inner side wall of the rotating member 142 and divide an inner cavity 142a of the rotating member 142 into a stator cavity 146 and a light cavity 148. The stator 12 may be disposed in the stator cavity 146. The lighting unit 30 and the audio unit 20 may be disposed in the light cavity 148.

More specifically, a length of the rotating member 142 along an axial direction of the motor shaft 40 may be greater than a length of the stator 12 along the axial direction of the motor shaft 40. The positioning plate 144 may be disposed in the inner cavity 142a of the rotating member 142 and further connected to the inner side wall of the rotating member 142, such that the inner cavity 142a of the rotating member 142 may be divided into the stator cavity 146 and the light cavity 148 distributed along the axial direction of the motor shaft 40. A clearance hole 145 may be defined in the positioning plate 144. The stator 12 may be disposed in the stator cavity 146 and abut against the positioning plate 144, such that the stator 12 may be positioned by the positioning plate 144. The motor shaft 40 may pass through the center of the stator 12, protrude out of the clearance hole 145 defined in the positioning plate 144, and further extend to the light cavity 148. The audio unit 20 may be provided on a portion of the motor shaft 40 protruding out of the clearance hole 145. That is to say, the audio unit 20 and the lighting unit 30 may be disposed at a side of the positioning plate 144 opposite to the stator 12.

By arranging the positioning plate 144 in the rotating member 142 to separate the stator 12 from the acoustic unit 20 and the lighting unit 30, the sealing of the stator cavity 146 may be improved, and the possibility of damage to the stator 12 caused by external impurities entering the stator cavity 146 through the light cavity 148 may be reduced.

Furthermore, as shown in FIG. 2, the lighting unit 30 may be arranged between the audio unit 20 and the positioning plate 144. The rotating wheel 100 may include a power supply member 50 disposed between the audio unit 20 and the lighting unit 30. The power supply member 50 may be in shape of a ring, may be slidable, and may be configured to electrically connect the audio unit 20 to the lighting unit 30.

More specifically, the acoustic unit 20 may be electrically connected to the power source via the power line, and further electrically connected to the audio source via the audio wire 92. Since the power wire 91 and the audio wire 92 are arranged inside the motor shall 40, it may be inconvenient to electrically connect the power wire 91 and the audio wire 92 to the lighting unit 30. In addition, since the lighting unit 30 is arranged on the rotor 14 or even fixed on the rotor 14, during the rotation of the rotor 14, the power wire 91 and the audio wire 92 electrically connected to the lighting unit 30 will also he twined with each other, which may affect the rotation of the lighting unit 30.

Therefore, in some embodiments of the present disclosure, the power supply member 50 may be disposed between the audio unit 20 and the lighting unit 300, and the power supply member 50 may be electrically connected to the power line and the audio wire 92. In this way, when the lighting unit 30 is rotating along with the rotor 14, the lighting unit 30 may keep abutting against the power supply member 50. Thus, the lighting unit 30 may be electrically connected to the power wire 91 and audio wire 92 via the power supply member 50. Therefore, it is possible not only omit the power wire and the audio wire which are connected to the lighting unit 30 and reduce the twining of the power wire 91 and the audio wire 92 which affects the rotation of the lighting unit 30, but also simplify the electrical connection structure between the lighting unit 30 and the power wire 91 and between the lighting unit 30 and the audio wire 92. Furthermore, the mounting process of the lighting unit 30 may also he simplified to improve the production and assembly efficiency.

FIG. 7 is an exploded view of the lighting unit 30 shown in FIG. 2. As further shown in FIG. 7, the lighting unit 30 may include a lighting circuit board 32, a lighting projection member 34, and a lighting strip 36.

The face cover 70 may be further configured to shield the audio unit 20 and the lighting unit 30, such that the appearance of the rotating wheel 100 may be more beautiful.

In some embodiments, as shown in FIGS. 1 and 2, the face cover 70 may be provided with a hollow portion, that is to say, a plurality- of through holes in same or different shapes may be defined in the face cover 70. The face cover 70 may be a light-transmitting component. More specifically, the hollow portion provided on the face cover 70 may facilitate the transmission of the sound of the audio unit 20 to obtain a larger volume. The -over 70 may be implemented as, for example, a light-transmitting component made of transparent plastic, such that the light emitted. from the lighting strip 36 may pass through the face cover 70 and further exit out of the face cover 70. In this way, it is possible to reduce the possibility of blocking the light emitted from the lighting strip 36.
