Description

Technical Field

[0001] The present invention relates to the field of camera technology, in particular to a camera module. Background Art

[0002] A camera module is an electronic module that integrates camera functions, usually including camera chips, lenses, image sensors, digital signal processors and other components. These modules can be widely used in various electronic devices, such as mobile phones, computers, smart homes, security monitoring and other fields;

[0003] Patent No. CN117724285A in the prior art is named as a camera module and its camera lens assembly. In the process of replacing the module, it is not necessary to remove the entire module from the circuit board. When the connector is horizontally plugged in, the connecting shell is pulled up. When the connecting shell moves up relative to the mounting seat, the connecting plate and the slide bar are driven to move up synchronously. The arc rail drives the sliding plate to move up. Since the insertion groove and the guide bar push each other, the guide seat moves backward, which separates the connector from the interface on the circuit board, and the separation force is in the horizontal direction, which can reduce the damage to the interface. When the connecting shell continues to move up, the connecting plate and the slide bar are driven to move up synchronously. When connecting the shell, the upward movement of the sliding rod will be blocked by the blocking bar. At this time, when the connecting plate continues to move upward, it will push the clamping plate, so that the limit bar can be separated from the inner side of the clamping plate, thereby achieving the purpose of separation, and completing the separation of the mounting base and the connecting shell, thereby solving the problem of disassembly and assembly in the later maintenance. The whole camera module needs to be disassembled, and the connector on the transmission belt needs to be separated from the interface separately during the disassembly process. Due to the small size of the interface and the connector, in most cases, the force applied during plugging and unplugging will cause the connector and the interface to be skewed, which can easily cause the pins at the interface to break and be damaged, causing inconvenience.

[0004] However, as the modern tourism industry is becoming more and more developed, more and more people like to travel around and take pictures. Nowadays, there are two main ways to take pictures: one is to use a mobile phone and the other is to use a camera. The mobile phone has the characteristics of small size and easy use, so it is chosen by most tourists as a photographic device. However, in some special cases, such as taking pictures of the sunrise at Taihu Lake or Lingshan Mountain and taking pictures when the outside sunlight is relatively strong, the high-brightness environment of the outside will directly affect the camera module installed in the mobile phone, causing glare and overexposure of the photos, thereby affecting the shooting effect. However, if a shading lens is directly installed in front of the camera module, although the shooting effect of the camera module under high light can be guaranteed, since the shading lens has the effect of blocking light, it will affect the shooting effect in low light environment. This camera module has low flexibility and is difficult to adapt to a variety of different environmental conditions. As the external environment changes, the camera head and its lens in the camera module may fog up, thereby affecting the shooting effect; therefore, it does not meet the existing needs, and we propose a camera module for this.

[0037] A shooting port 22 penetrating the synchronous circular plate 7 and the externally threaded circular plate 10 is provided in the middle of the upper end surface of the synchronous circular plate 7 , and the position of the shooting port 22 corresponds to the position of the shooting head 3 . The shooting head 3 can shoot the outside through the shooting port 22 .

[0038] A strip groove A12 is provided on both sides of the lower end surface of the externally threaded circular plate 10, and the top end of the arc plate 14 is inserted into the interior of the strip groove A12. An inclined push plate 13 fixed to the interior of the strip groove A12 is provided above the arc plate 14, and the surface of the inclined push plate 13 facing the arc plate 14 is an inclined surface. One side of the upper end surface of the arc plate 14 is arc-shaped, and the arc surface located on the upper end surface of the arc plate 14 fits with the inclined push plate 13; an annular groove 16 is provided below the two arc plates 14, and a synchronous annular base 17 connected to the inner wall of the annular groove 16 through a roller bearing is provided inside the annular groove 16, and both sides of the upper end surface of the synchronous annular base 17 are provided A strip groove B18, a short rod 19 is fixedly provided inside the strip groove B18, a spring 21 is sleeved on the outer surface of the short rod 19, one end of the spring 21 is connected to a metal sleeve 20 movably sleeved on the outer surface of the short rod 19, and the surface of the metal sleeve 20 facing the arc plate 14 is fixed to the arc plate 14; as the external thread circular plate 10 descends, the inclined push plate 13 fixed thereto will also move downward, and through the inclined surface located on the outer surface of the inclined push plate 13, the downward moving inclined push plate 13 can push the arc plate 14 inward, and as the arc plate 14 moves, the arc-shaped defogger cotton strip 15 located on the outer surface of the arc plate 14 will contact the shooting head 3;

[0039] Since the top end of the arc plate 14 is inserted into the strip groove A12 located at the lower end surface of the externally threaded circular plate 10, when the externally threaded circular plate 10 rotates, the arc plate 14 will rotate along with it, and when the arc-shaped defogger strip 15 in contact with the outer surface of the shooting head 3 moves downward while rotating, the outer surface of the shooting head 3 can be defogged;

[0040] When the neutral density lens 209 is moved to the top of the shooting head 3, the lower end surface of the neutral density lens 209 will contact with the cleaning sponge 24 fixed to the upper end surface of the L-shaped lens defogger rod 23. When the arc plate 14 is rotated and pushed inward, the cleaning sponge 24 will move along with it. The neutral density lens 209 being used can be defogged by the cleaning sponge 24 that is rotated and pushed inward. The above technical solution can automatically defog the lens moved above the shooting head 3 and the shooting head 3, so as to ensure that the photos taken by them will not be affected by fog, thereby ensuring the shooting quality of the camera module 1.

[0041] When the arc plate 14 is pushed inward, the metal sleeve 20 fixed thereto will also move inward and squeeze the spring 21. When the defog of the shooting head 3 and the lens is completed, the small motor 4 is started to drive the transmission shaft 5 to rotate in the opposite direction to drive the external thread circular plate 10 to move upward. When the external thread circular plate 10 moves upward, the inclined surface pushing plate 13 can be gradually pushed back to its original position through the reaction force of the squeezed spring 21. Since the synchronous annular base 17 indirectly connected to the metal sleeve 20 is connected to the annular groove 16 through a roller bearing, when the arc plate 14 is driven to rotate, the synchronous annular base 17 will rotate synchronously inside the annular groove 16. Through this roller bearing structure, the arc plate 14 is prevented from being unable to rotate due to the metal sleeve 20.
