[0002] With the continuous development of smart home, people's requirements for the safety, aesthetics and intelligence of home devices are getting higher and higher.

This kind of camera module has broad application prospects in the field of smart home and can realize multiple functions such as home monitoring, intelligent security, and remote interaction.

[0003] At present, in the application of the hidden camera module, although a certain degree of hiding effect can be achieved, the camera module is easily affected by dust when hidden. The entry of dust may affect the imaging quality of the camera and reduce the image clarity. However, most hidden camera modules are not convenient for effectively protecting the camera module when hidden, and there are certain deficiencies. Content of the Utility Model

Detailed implementation mode

[0021] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0022] As Figures 1 to 5 shown, a hidden camera module includes a housing 1, and a through hole 2 is provided on the housing 1. The diameter size of the through hole 2 should be slightly larger than the diameter size of the camera module body 9 to avoid friction between the camera module body 9 and the inner wall of the through hole 2.

[0023] A transmission mechanism 3 is provided inside the housing 1. The transmission mechanism 3 includes a motor 301 fixedly installed on the inner wall of the housing 1. The output end of the motor 301 is fixedly connected to a rotating shaft 302, and the rotating shaft 302 is rotatable with respect to the housing 1. The end of the rotating shaft 302 away from the motor 301 is fixedly connected to a first gear 303. The outer surface of the first gear 303 is meshed with a second gear 304. The outer surface of the second gear 304 is fixedly connected to a limiting member 305, and the outer surface of the limiting member 305 is rotatable with respect to the inner wall of the housing 1. The limiting member 305 is divided into two parts, a rotating rod plus a rotating piece, which can limit the first gear 303 and improve the stability of the first gear 303 during rotation. The outer surface of the second gear 304 is meshed with a third gear 306. The end of the adjusting screw 307 close to the third gear 306 is also provided with a rotating rod plus a rotating piece, which can limit the third gear 306 and the adjusting screw 307 and improve the stability of the third gear 306 and the adjusting screw 307 during rotation.

[0024] The inner wall of the third gear 306 is fixedly connected to an adjusting screw 307. The outer surface of the adjusting screw 307 is rotatable with respect to the inner wall of the housing 1, and the adjusting screw 307 is threadedly connected to the moving plate 5.

[0025] Turn on the motor 301. At this time, the motor 301 will drive the rotating shaft 302 and the first gear 303 to rotate. Then the first gear 303 will drive the second gears 304 on both sides to rotate, and further the second gears 304 will drive the third gears 306 and the adjusting screws 307 on both sides to rotate. At this time, the adjusting screw 307 will drive the moving plate 5 to move, and further drive the column 6, the ball 7 and the camera module body 9 to move, so as to be able to adjust the working state of the camera module body 9.

[0026] Inside the housing 1, a sealing mechanism 4 is provided. The sealing mechanism 4 includes two limiting rods 401 fixedly connected to the inner wall of the housing 1. The outer surfaces of the limiting rods 401 are slidably connected with two moving frames 402, and the moving frames 402 are in rolling contact with the balls 7. The surface of the moving frame 402 in contact with the ball 7 is set as an inclined surface, so that the ball 7 can push the moving frame 402 to gradually move on the limiting rod 401. On the outer surfaces of the two moving frames 402 close to each other, a sealing door 403 is fixedly connected respectively. A elastic member 404 is sleeved on the outer surfaces of the two limiting rods 401, and the material of the elastic member 404 is a spring. The two ends of the elastic member 404 are fixedly connected to the outer surfaces of the two moving frames 402 close to each other respectively.

[0027] By moving the two moving frames 402 away from each other, the two moving frames 402 will stretch the elastic member 404. At this time, the elastic member 404 will deform and store a certain amount of elastic potential energy. When the force applied to the moving frame 402 is released, the compressed elastic member 404 will release the elastic potential energy, and then drive the two moving frames 402 to move close to each other, so as to achieve the rapid reset effect of the two moving frames 402.

[0028] A limiting chute 8 is provided on the inner wall of the housing 1, and a moving plate 5 is slidably connected to the inner wall of the limiting chute 8. The limiting chute 8 can limit the moving plate 5, so as to improve the stability of the moving plate 5 during the moving process. A column 6 is fixedly connected to the outer surface of the moving plate 5, and a ball 7 is embedded at one end of the column 6 away from the moving plate 5.

[0029] There are two columns 6, and a ball 7 is embedded at one end of each column 6 close to the moving frame 402. The ball 7 can roll in the column 6, and the column 6 can limit the ball 7 to prevent the ball 7 from slipping off. A camera module body 9 is fixedly installed on the outer surface of the moving plate 5.

[0030] Working principle: When the camera module body 9 needs to be used, the motor 301 can be turned on through an external controller. At this time, the motor 301 drives the rotating shaft 302 and the first gear 303 to rotate. Then, the first gear 303 drives the second gears 304 on both sides to rotate, and further enables the second gears 304 to drive the third gears 306 and the adjusting screw 307 on both sides to rotate. At this time, the adjusting screw 307 drives the moving plate 5 to move closer to the through hole 2, and then drives the column 6, the ball 7, and the camera module body 9 to move accordingly. During the movement, the ball 7 contacts the inclined surface of the moving frame 402 and exerts pressure on the moving frame 402, thereby pushing the two moving frames 402 to move away from each other. Further, the two moving frames 402 stretch the elastic member 404. At this time, the elastic member 404 deforms and stores a certain amount of elastic potential energy. At the same time, the two moving frames 402 drive the two sealing doors 403 to move away from each other, and then the blocked through hole 2 can be gradually opened, enabling the camera module body 9 to smoothly pass through the through hole 2, so that the camera module body 9 enters the working state. When the camera module body 9 needs to be hidden, only need to turn on the motor 301 to rotate it in the reverse direction. At this time, the adjusting screw 307 drives the moving plate 5 to move horizontally away from the through hole 2. Then, the moving plate 5 drives the column 6, the ball 7, and the camera module body 9 to move accordingly. The column 6 and the ball 7 reduce the thrust applied to the moving frame 402. At this time, the compressed elastic member 404 releases the elastic potential energy, and then drives the two moving frames 402 to move closer to each other. At the same time, the two moving frames 402 drive the two sealing doors 403 to move closer to each other, and then the through hole 2 can be timely blocked. Through the mutual cooperation of the transmission mechanism 3, the column 6, the ball 7, and the sealing mechanism 4, dust can be prevented from entering the housing 1, and then it is convenient to timely and effectively protect the camera module body 9 when it is hidden.

[0031] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
