The second end of the catheter tube 61 extends into the receiving cavity, and a sealing ring 62 may be provided between the catheter tube 61 and the through hole 413 to improve the sealing performance of the liquid flow. When the driving motor 20 is switched between the first state and the second state, the liquid is introduced into the accommodation chamber through the catheter 61, or the liquid in the accommodation chamber is guided back to the installation chamber 14 through the catheter 61, so that the movable bracket 42 is The fixed bracket 41 is movable so as to adjust the distance between the second lens assembly 52 and the first lens assembly 51 , so as to realize the adjustment of the focal length of the camera module 100 .

Specifically, the vertical gear 71 is connected to the drive motor 20 , and the horizontal gear 72 is meshed with the vertical gear 71 . The first end of the guide rod 73 is connected to the horizontal gear 72 , and the second end of the guide rod 73 is connected to the first hydraulic gear 31 , so that the horizontal gear 72 drives the first hydraulic gear 31 to rotate.

When the drive motor 20 rotates in the forward direction, the first hydraulic gear 31 and the second hydraulic gear 32 form a positive pressure at the liquid outlet, and a negative pressure at the liquid inlet, so that the liquid in the liquid storage tank 13 is introduced into the first hydraulic gear 31 The meshing gap with the second hydraulic gear 32 simultaneously squeezes the fluid between the first hydraulic gear 31 and the second hydraulic gear 32 into the catheter tube 61 .

Since the catheter 61 is inserted into the accommodating cavity, the extruded liquid enters between the first lens assembly 51 and the second lens assembly 52 in the accommodating cavity, and the first lens assembly 51 and the second lens assembly 52 can form a zoom module. The hydraulic pressure pushes the movable bracket 42 out, and the second lens assembly 52 is fixed on the movable bracket 42 , while the first lens assembly 51 is installed on the fixed bracket 41 . The resulting pressure pushes the sliding bracket to take the second lens assembly 52 away from the first lens assembly 51, thereby increasing the zoom factor, and then taking pictures of distant scenery.

The cover 12 is provided with a connection hole 15, and the guide rod 73 connects the first hydraulic gear 31 and the horizontal gear 72 through the connection hole 15, so that the drive motor 20 can indirectly drive the first hydraulic gear 31 to rotate, and realize the first lens assembly 51 and the second lens assembly 51. The distance between lens assemblies 52 is adjusted.

According to an embodiment of the present invention, the fixed bracket 41 is a square frame body, and the square frame body is provided with a light hole 412 communicating with the first chamber 411 , and light can be introduced into or out of the fixed bracket 41 through the light hole 412 .

Of course, in this application, a concave lens 521 may also be provided in the first lens assembly 51 , and a convex lens 511 may be provided in the second lens assembly 52 , which will not be described in detail in this application.

This application mainly utilizes the telescope principle by using the concave lens 521 and the convex lens 511 to form a zoom. The real image formed by the refraction of light through the objective lens is on the focal point behind the eyepiece (near the back of the human eye), and this image is a virtual image to the eyepiece. Therefore, it becomes a magnified upright virtual image after being refracted by it. The magnification of a telescope is equal to the ratio of the focal length of the objective lens to the focal length of the eyepiece. Its advantage is that the lens barrel is short and can form a positive image, but its field of view is relatively small. The telescope made of a concave lens 521 (eyepiece) and a convex lens 511 (objective lens) has the advantage of simple structure and can directly form a positive image.
