Description

Technical Field

[0001] This utility model relates to the field of noise reduction technology for electronic devices, and specifically to a noise reduction structure for a camera. Background Technology

[0002] Currently, most pop-up cameras on the market use motors to drive the camera module for lifting and lowering. Because motors themselves are noisy, and this noise is further amplified when the motor is assembled with multiple parts, and then integrated into the screen, the noise is amplified many times over due to resonance, acoustic cavities, and other factors, severely impacting the user experience. Therefore, reducing the noise level of the motors within pop-up cameras is a pressing issue that needs to be addressed. Utility Model Content

[0003] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a camera noise reduction structure that can reduce the noise level of the motor inside the lifting camera.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a camera noise reduction structure, comprising a bracket, a motor assembly, and a locking assembly. The motor assembly includes a housing and a motor. The locking assembly is used to lock the housing onto the bracket and includes a limiting sleeve. The limiting sleeve is fixedly disposed on the housing. A limiting groove is formed inside the limiting sleeve. The motor is located within the limiting groove and is bonded to the inner wall of the limiting groove.

[0005] Furthermore, at least one slot is formed on the outer peripheral surface of the limiting sleeve, and the slot communicates with the limiting groove.

[0006] Furthermore, there are two slots, which are located on opposite sides of the motor.

[0007] Furthermore, the inner wall of the limiting groove is provided with at least one adhesive portion.

[0008] Furthermore, foam is provided on the adhesive part, and the motor is adhered to the foam.

[0009] Furthermore, the locking assembly includes a locking bolt and a silicone washer. The locking bolt is disposed on the housing, and the threaded end of the locking bolt passes through the housing and connects to the threaded hole of the bracket. The silicone washer is sleeved on the locking bolt and is located between the head of the locking bolt and the housing.

[0010] Furthermore, the housing is provided with an annular groove, and the silicone gasket is disposed on the annular groove.

[0011] Furthermore, the silicone gasket is annular.

[0012] Furthermore, the silicone gasket is higher than the annular groove.

[0013] Furthermore, the number of locking components is three, and the three locking components are respectively located on both sides and one end of the housing.

[0014] The beneficial effects of this utility model are as follows: The noise reduction structure for a camera provided by this utility model adopts a semi-enclosed design for the motor. On the one hand, the motor is prevented from being suspended in the air by the limiting sleeve, and on the other hand, the motor and the limiting sleeve are fixed by adhesive bonding to avoid fixing stress, so that the amplitude of the motor is smaller when it is working. Therefore, the noise level of the motor in the lifting camera can be reduced. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] In this application, unless otherwise expressly specified and limited, the terms "connection" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] In the description of this application, it should be understood that the terms "longitudinal", "horizontal", "level", "top", "bottom", "upper", "lower", "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly defined.

[0023] like Figures 1-3 As shown, this utility model provides a camera noise reduction structure, including a bracket 10, a motor assembly 20, and a locking assembly 30. The motor assembly 20 includes a housing 21 and a motor 22. The locking assembly 30 is used to lock the housing 21 onto the bracket 10. The above are all prior art, and the specific structure will not be described in detail here.

[0024] This utility model also includes a limiting sleeve 40, which is fixedly mounted on the housing 21. A limiting groove 41 is formed inside the limiting sleeve 40. The motor 22 is located inside the limiting groove 41, and a gap is reserved between the motor 22 and the inner wall of the limiting groove 41 to facilitate bonding the two together by adhesive.

[0025] In this utility model, the motor 22 adopts a semi-enclosed design. On the one hand, the limiting sleeve 40 prevents the motor 22 from being suspended, thereby reducing its vibration and amplitude. On the other hand, the motor 22 and the limiting sleeve 40 are bonded together to avoid fixing stress, so that the amplitude of the motor 22 is smaller when it works. Therefore, the noise level of the motor 22 inside the lifting camera can be reduced.

[0026] In one embodiment, at least one slot 42 is formed on the outer peripheral surface of the limiting sleeve 40, and the slot 42 communicates with the limiting groove 41. The design of the slot 42 can increase the number of bonding points between the motor 22 and the inner wall of the limiting groove 41, and also facilitate the dispensing operation by the operator.

[0027] In one embodiment, there are two slots 42, which are located on opposite sides of the motor 22. Adhesive bonding between the motor 22 and the inner wall of the limiting slot 41 at both the top and bottom positions further improves the stability of the motor 22.

[0028] In one embodiment, the inner wall of the limiting groove 41 is provided with at least one adhesive portion.

[0029] In this embodiment, foam is provided on the adhesive part, and the motor 22 is adhered to the foam.

[0030] The design of the adhesive part and foam can further bond the motor 22 to the inner wall of the limiting groove 41; on the other hand, it can further avoid hard contact between the motor 22 and the inner wall of the limiting groove 41, and further reduce the noise level of the motor 22 in the lifting camera.

[0031] In one embodiment, the locking assembly 30 includes a locking bolt 31 and a silicone washer 32. The locking bolt 31 is disposed on the housing 21, and the threaded end of the locking bolt 31 passes through the housing 21 and connects to the threaded hole of the bracket 10. The silicone washer 32 is sleeved on the locking bolt 31, and the silicone washer 32 is located between the head of the locking bolt 31 and the housing 21.

[0032] This embodiment is based on the principle that the noise is amplified due to resonance after the motor assembly 20 is installed. When installing the motor assembly 20, a silicone gasket 32 ​​is added to make soft contact. By controlling the tightening length of the locking bolt 31, the preload of the silicone gasket 32 ​​is controlled, thereby changing the vibration frequency of the motor assembly 20, reducing the risk of resonance between the motor assembly 20 and components such as the bracket 10, and achieving noise reduction design.

[0033] In one embodiment, the housing 21 is provided with an annular groove 23, and the silicone gasket 32 ​​is disposed on the annular groove 23.

[0034] In this embodiment, the silicone gasket 32 ​​is annular to better fit the shape of the locking bolt 31.

[0035] In this embodiment, the silicone gasket 32 ​​is higher than the annular groove 23.

[0036] The annular groove 23 can be made of silicone. Its design can limit the silicone gasket 32 ​​and further limit the locking bolt 31, thereby improving the stability of the structure and reducing the resonance effect caused by vibration, thus reducing noise.

[0037] In one embodiment, the number of locking components 30 is three, and the three locking components 30 are respectively located on both sides and one end of the housing 21. The three locking components 30 are arranged in a triangular shape to fix the housing 21, which provides a better fixing effect.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
