The hydraulic pump 30 of the present application, which is an intermeshing process by 2 gears (a first hydraulic gear 31 and a second hydraulic gear 32), is also referred to as a gear pump, or as a positive displacement device. The hydraulic pump 30 of the present application acts like a piston in one cylinder, and when one tooth enters the fluid space of another tooth, the fluid is mechanically displaced.

According to an embodiment of the present invention, the camera module 100 further includes: the liquid guide pipe 61, a first end of the liquid guide pipe 61 is positioned in the installation cavity 14, the liquid guide pipe 61 corresponds to the radial center position between the first hydraulic gear 31 and the second hydraulic gear 32, and a second end of the liquid guide pipe 61 is positioned in the accommodating cavity.

In other words, as shown in fig. 1, the camera module 100 may further include a liquid guide tube 61, a first end of the liquid guide tube 61 extends into the mounting cavity 14 through the through hole 413, and the liquid guide tube 61 corresponds to a radial center position between the first hydraulic gear 31 and the second hydraulic gear 32, so that the liquid guide tube 61 is directly opposite to a position where the first hydraulic gear 31 and the second hydraulic gear 32 are meshed with each other. The second end of the liquid guide tube 61 extends into the accommodating cavity, and a sealing ring 62 can be arranged between the liquid guide tube 61 and the through hole 413, so that the flowing tightness of liquid is improved. When the driving motor 20 is switched between the first state and the second state, the liquid is introduced into the accommodating cavity through the liquid guide tube 61, or the liquid in the accommodating cavity is introduced back into the mounting cavity 14 through the liquid guide tube 61, so that the movable bracket 42 is movable on the fixed bracket 41, the distance between the second lens assembly 52 and the first lens assembly 51 is conveniently adjusted, and the size adjustment of the focal length of the camera module 100 is further realized.

According to an embodiment of the present invention, the camera module 100 further includes a vertical gear 71, a horizontal gear 72, and a guide rod 73.

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

That is, referring to fig. 1 and 2, the camera module 100 may further include a vertical gear 71, a horizontal gear 72, and a guide rod 73. Wherein the vertical gear 71 is connected to the driving motor 20, and the driving motor 20 can convert the horizontal rotation into the vertical rotation of the vertical gear 71. The horizontal gear 72 is engaged with the vertical gear 71, and the horizontal gear 72 converts the vertical rotation of the vertical gear 71 into horizontal rotation. A first end of the guide rod 73 is connected to the horizontal gear 72, and a second end of the guide rod 73 is connected to the first hydraulic gear 31. The first end and the second end of the guide rod 73 are both ends of the guide rod 73 in the length direction, respectively. Of course, the first end of the guide rod 73 and the second end of the guide rod 73 may be connected to the horizontal gear 72 and the first hydraulic gear 31 through the sealing ring 62, respectively. The horizontal gear 72 drives the first hydraulic gear 31 to rotate through the guide rod 73, so as to bring the first hydraulic gear 31 and the second hydraulic gear 32 in the hydraulic pump 30 to rotate in an engaged manner.

Alternatively, the vertical gear 71 and the horizontal gear 72 are bevel gears, respectively. Bevel gears may be used to transmit motion and power between two intersecting shafts. In a typical machine, the angle of intersection between the two axes of the bevel gear is equal to 90 ° (but may not be equal to 90 °). Like cylindrical gears, bevel gears have reference cones, addendum cones, dedendum cones, base cones, and the like. The cone has a large end and a small end, and the circles corresponding to the large end are respectively called a reference circle (the radius of the reference circle is r), an addendum circle, a dedendum circle and a base circle. The motion of a pair of bevel gears is equivalent to that of a pair of pitch cones for pure rolling. Bevel gears, also known as bevel gears, are used for transmission between intersecting shafts. Bevel gears can change the direction of transmission compared to cylindrical gears. The single stage transmission ratio can reach 6, and the maximum single stage transmission ratio can reach 8.

In the present application, referring to fig. 3, the driving motor 20 rotates in a forward direction (first state) to convert a horizontal rotation into a vertical rotation through the vertical gear 71 (bevel gear), and rotates the first hydraulic gear 31 and the second hydraulic gear 32 through the horizontal gear 72. When the driving 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 meshing gap between the first hydraulic gear 31 and the second hydraulic gear 32, and the liquid between the first hydraulic gear 31 and the second hydraulic gear 32 is pressed into the liquid guide tube 61.

Because catheter 61 inserts and holds the chamber, between first lens subassembly 51 and the second lens subassembly 52 in the liquid entering of extruding held the chamber, first lens subassembly 51 and second lens subassembly 52 can constitute the module of zooming. The pressure generated by the hydraulic pressure pushes the movable bracket 42 to extend, the second lens assembly 52 is fixed on the movable bracket 42, and the first lens assembly 51 is mounted on the fixed bracket 41. Finally, the formed pressure pushes the sliding support to drive the second lens assembly 52 to be far away from the first lens assembly 51, zooming times are increased, and then a picture can be taken of a distant scene.

On the contrary, when the drive motor 20 rotates in reverse (the second state), the first hydraulic gear 31 and the second hydraulic gear 32 of the hydraulic pump 30 are respectively rotated in reverse, and the liquid between the first hydraulic gear 31 and the second hydraulic gear 32 is introduced into the reservoir 13. Form the negative pressure at catheter 61, and then introduce hydraulic pump 30 with the liquid between first lens subassembly 51 and the second lens subassembly 52, the negative pressure of production will promote movable support 42 and take second lens subassembly 52 to be close to the activity of first lens subassembly 51, realizes reducing the zoom multiple, and then can shoot near the scenery.

In some embodiments of the present invention, referring to fig. 1 and 2, the base 10 is mainly composed of a base body 11 and a cover 12. The cross section of the base body 11 is square, the driving motor 20 is disposed on the base body 11, and the fixing bracket 41 is disposed on the first side of the base body 11. The cover 12 may be covered on a portion of the base body 11, and the cover 12 and the base body 11 cooperate to define a reservoir 13 and a mounting cavity 14. The cover body 12 is provided with a connecting hole 15, and the guide rod 73 is connected with the first hydraulic gear 31 and the horizontal gear 72 through the connecting hole 15, so that the driving motor 20 can indirectly drive the first hydraulic gear 31 to rotate, and the distance between the first lens assembly 51 and the second lens assembly 52 can be adjusted.

According to an embodiment of the present invention, the fixing bracket 41 is a square bracket body, and the square bracket body is provided with a light passing hole 412 communicated with the first chamber 411, so that light can be guided into or out of the fixing bracket 41 through the light passing hole 412. A portion of the first lens assembly 51 corresponds to the position of the light passing hole 412. The movable bracket 42 and the fixed bracket 41 are respectively arranged on the same side of the base 10, and the movable bracket 42 can be movable in the length direction of the fixed bracket 41.

In the present application, referring to fig. 1, 4 and 5, first lens assembly 51 includes a convex lens 511 and a periscope 512. The periscope 512 corresponds to the position of the light-passing hole 412. The second lens assembly 52 includes a concave lens 521 and a chip 522, wherein the concave lens 521 and the convex lens 511 are disposed oppositely, and the chip 522 is disposed on a side of the movable bracket 42 away from the fixed bracket 41. The movable bracket 42, the chip 522, the concave lens 521, the convex lens 511, the periscope 512, the fixed bracket 41, and the like may constitute the zoom system of the present application. The specific number of the convex lenses 511 and the concave lenses 521 in the first lens assembly 51 and the second lens assembly 52 can be specifically limited according to actual needs. Of course, in the present application, the concave lens 521 may be disposed in the first lens assembly 51, and the convex lens 511 is disposed in the second lens assembly 52, which are not described in detail herein.

The present application mainly utilizes the principle of a telescope by using a concave lens 521 and a convex lens 511 to form a zoom. The real image formed by the refraction of the light rays through the objective lens is at a focus behind the ocular lens (behind the ocular lens), which is a virtual image of the ocular lens. Thus, it is refracted into an enlarged orthoscopic virtual image. The magnification of the telescope is equal to the ratio of the focal length of the objective lens to the focal length of the eyepiece. Its advantage is short lens barrel for positive image, but its visual field is small. The telescope comprising a concave lens 521 (eyepiece) and a convex lens 511 (objective lens) has the advantages of simple structure and capability of directly forming positive images.
