This casing usually comprises a fixed portion connected to the motor stator and a rotating portion connected to the motor rotor. In the prior art, bearings are used between the two portions of the casing to ensure smooth relative rotation when the motor is rotating. However, the use of bearings increases the structural complexity of the rotating assembly and is also costly. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

For example, they can be fixed connections, integral connections, or detachable connections; they can be mechanical connections or electrical connections, or internal connections between two components; they can be direct connections or indirect connections through an intermediate medium.

[0026] This application provides a rotating component, for example, please refer to [link to example]. Figures 1-3 , Figure 1 This is a schematic diagram of the structure of the rotating assembly provided in the embodiments of this application. Figure 2 for Figure 1 The exploded view of the rotating assembly shown. Figure 3 for Figure 1 The rotating assembly 100 is shown in cross-sectional view. The rotating assembly 100 includes an upper cover 110, a lower cover 120, and a bracket 130.

[0027] The upper cover 110 and the lower cover 120 form a receiving space 140 for accommodating the motor and are used for rotational connection via the motor. A bracket 130 is disposed in the receiving space 140 to support the motor. The bracket 130 is fixedly connected to the upper cover 110 and includes an elastic damping part 131, which is used to deform to absorb energy from motor vibration.

[0028] The upper cover 110 and the lower cover 120 are arranged opposite each other at a distance. Preferably, the circumferential sidewall of the upper cover 110 is sleeved outside the circumferential sidewall of the lower cover 120. This structure helps to improve the stability of the rotational connection between the upper cover 110 and the lower cover 120.

[0029] In practical applications, the motor generates vibrations during operation. When these vibrations are transmitted to the bracket 130, the elastic damping part 131 deforms to absorb the energy from the vibrations, thereby reducing the vibrations transmitted to the upper cover 110 and the lower cover 120 and improving the stability of the upper cover 110 and the lower cover 120 when they rotate relative to each other. Preferably, multiple elastic damping parts 131 are arranged sequentially at intervals along the circumference of the motor.

[0030] The rotating assembly 100 provided in this application embodiment reduces the vibration transmitted to the upper cover 110 and lower cover 120 by adding a bracket 130 for supporting the motor and by setting a deformation-absorbing device on the bracket 130 to absorb the energy from the vibration during motor operation, thereby improving the stability of the upper cover 110 and lower cover 120 when they rotate relative to each other. The rotating assembly 100 of this application does not require the installation of bearings to improve rotational stability, which can reduce product costs.

[0031] For example, please refer to Figure 4 , Figure 4 This is a schematic diagram of the support structure provided in an embodiment of this application. The elastic damping part 131 includes an elastic cantilever 1311, which is used to deform to absorb energy from motor vibration. In practical applications, when the vibration generated by the motor during operation is transmitted to the support 130, the elastic cantilever 1311 will continuously swing. During this process, the elastic cantilever 1311 absorbs the energy from the vibration through deformation, converting kinetic energy into elastic potential energy, and then releases the energy during the process of returning to its original state, thereby reducing the vibration ultimately transmitted to the upper cover 110 and the lower cover 120, and improving the stability of the upper cover 110 and the lower cover 120 when they rotate relative to each other.

[0032] In some embodiments, the elastic cantilever 1311 includes a free end disposed opposite to the lower cover 120, and a buffer protrusion 1312 is provided on the side of the free end facing the lower cover 120. Thus, during the swinging process of the elastic cantilever 1311, the buffer protrusion 1312 disposed between the free end and the lower cover 120 provides cushioning, preventing the free end from colliding with the lower cover 120 and generating significant noise. Furthermore, the buffer protrusion 1312, in fulfilling its cushioning function, can also absorb some of the energy from vibrations, thereby further improving the shock absorption effect. Optionally, the buffer protrusion 1312 is made of a flexible material such as rubber. Optionally, a buffer gap is provided between the buffer protrusion 1312 and the lower cover 120, thereby further preventing the free end from colliding with the lower cover 120 and generating significant noise.

[0033] Optionally, the elastic cantilever 1311 extends radially along the motor, and multiple elastic cantilever 1311 are arranged sequentially at intervals along the circumference of the motor. For example, there are 6 elastic cantilever 1311, so as to absorb the kinetic energy at different positions on the support 130 respectively.

[0034] In some embodiments, such as Figure 5 As shown, Figure 5 This is a schematic diagram of the bracket provided in an embodiment of this application from another perspective. The bracket 130 includes a bottom wall 132, a first through hole 133 formed in the bottom wall 132, and a first side wall 134 disposed on the bottom wall 132. The first side wall 134 is disposed around the first through hole 133. The first side wall 134 and the bottom wall 132 form a first limiting groove 135, which is used for limiting the installation of the motor, and the first through hole 133 is used for the motor's rotating shaft to pass through. This helps to improve the stability of the motor installed on the bracket 130.

[0035] Preferably, such as Figure 4 As shown, a notch is provided at the edge of the bottom wall 132, and an elastic cantilever 1311 is disposed in the notch. The elastic cantilever 1311 includes a connecting part, a deformable part, and a free end connected in sequence. The connecting part is connected to the inner wall of one side of the notch, and the deformable part and the free end are spaced apart from the inner wall of the notch.

[0036] Optionally, the upper cover 110 is also provided with a second limiting groove 111, which is opposite to the first limiting groove 135 and forms a limiting space for the fixed installation of the motor body. A connecting post is provided in the lower shell for fixed connection with the motor shaft. Understandably, when the motor is running, the motor shaft rotates relative to the main body, thereby causing relative rotation between the upper cover 110 and the lower cover 120.

[0037] In some embodiments, a second through hole 136 is also provided on the bottom wall 132. The second through hole 136 is located on the outer side of the first side wall 134 and is used for threading the wire harness. This avoids the presence of the bracket 130 from affecting the wiring of the product. Preferably, the shape of the second through hole 136 matches the movement trajectory of the wire harness relative to the bracket 130. In this way, even when the wire harness moves relative to the bracket 130, the two will not interfere with each other, thus avoiding frequent bending of the wire harness and shortening its service life.

[0038] Optionally, the top cover 110 includes a first connecting portion 112, and the bracket 130 includes a second connecting portion 137 connected to the first connecting portion 112. A buffer is provided between the first connecting portion 112 and the second connecting portion 137. The buffer can be made of a flexible material. In this way, by utilizing the buffer function, the vibration transmitted from the bracket 130 to the top cover 110 can be reduced, thereby further improving the stability of the rotating assembly 100 during rotation. The first connecting portion 112 is, for example, a stud, and the second connecting portion 137 includes a threaded hole. Screws are sequentially passed through the threaded hole and screwed onto the stud to achieve the connection between the first connecting portion 112 and the second connecting portion 137.

[0039] The rotating assembly 100 provided in this application embodiment reduces the vibration transmitted to the upper cover 110 and lower cover 120 by adding a bracket 130 for supporting the motor and by setting a deformation-absorbing device on the bracket 130 to absorb the energy from the vibration during motor operation, thereby improving the stability of the upper cover 110 and lower cover 120 when they rotate relative to each other. The rotating assembly 100 of this application does not require the installation of bearings to improve rotational stability, which can reduce product costs.

[0040] This application also provides a camera, which includes the rotating component 100 in any of the above embodiments.

[0041] The camera provided in this application embodiment has a rotating assembly 100 that adds a bracket 130 to support the motor. The bracket 130 is configured to absorb energy from vibrations during motor operation through deformation, thereby reducing the vibration transmitted to the upper cover 110 and lower cover 120, improving the stability of the upper cover 110 and lower cover 120 during relative rotation, and thus ensuring the stability of the camera lens during rotation. The rotating assembly 100 in this application's camera does not require bearings to improve rotational stability, thus reducing product costs.

[0042] The rotating component and camera provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
