The function of moving the lens group makes the lens 1000 more tolerant, and the entire lens 1000 will not lose its function due to the damage of a certain sub-driver. It can be understood that, because the multiple sub-driving elements are symmetrically distributed with respect to the mirror group, they are evenly distributed on the edge of the mirror group, so that the driving force of the multiple sub-driving elements acting on the mirror group is more uniform, thereby improving the driving of the driving element 300. The stability and accuracy of the lens group.

Please also refer to FIG. 4. FIG. 4 is a cross-sectional view of the driving element 300 in the lens 1000 in the direction A-A in the third embodiment.

In one embodiment, the driving member 300 is a driving sleeve, that is, the first driving member 310 is a sleeve structure, the first driving member 310 is sleeved on the periphery of the first lens group 210, and/or the second driving member 320 is a sleeve In a cylindrical structure, the second driving member 320 is sleeved on the periphery of the second lens group 220. When the first driving part 310 and/or the second driving part 320 is a sleeve structure, since the driving part 300 is installed between the lens group and the bracket 100, the driving part 300 is in a fully covered state, that is, the driving part 300 is set in a sleeve On the lens group, the entire edge of the lens group is wrapped. It can be seen that when this type of driving member 300 drives the lens group, the driving force acting on the lens group covers the entire edge of the lens group, so that the driving member 300 The driving force acting on the lens group is more uniform, which further improves the stability and accuracy of the driving part 300 driving the lens group.

It is understandable that the first driving part 310 and the second driving part 320 may adopt micro-electromechanical technology. In one embodiment, the first driving part 310 is a MEMS driving part, and/or the second driving part 320 is a MEMS driving part. Pieces.

The second movable part can move relative to the second fixed part along the central axis of the inner space of the bracket 100 to drive the first lens group 210 to move. It can be understood that the first driving member 310 and the second driving member 320 can be any structure that satisfies the corresponding driving function, and is not specifically limited here.

Please also refer to FIG. 5. FIG. 5 is a schematic structural diagram of a lens 1000 provided with a third lens group 230 according to the second embodiment of the present application.

In an embodiment, the zoom assembly 200 further includes a third lens group 230, wherein the third lens group 230, the first lens group 210, and the second lens group 220 are arranged in sequence along the central axis of the accommodating space, and the first lens group 230 The three lens group 230 is close to the light inlet 101, and the third lens group 230 is fixedly connected to the bracket 100 for angle adjustment of the incoming light. The light will first pass through the third lens group 230 before entering the first lens group 210 and the second lens group 220. Therefore, when the third lens group 230 is present, the light can be adjusted in advance for better control. The angle of the incoming light, the coordination between the first lens group 210 and the third lens group 230 can better adjust the magnification, so that the lens 1000 can better achieve fast and stepless optical zoom.

It is understandable that the number of lenses in the third lens group 230 can also be one or more, and the surface structure and arrangement of each lens can be various, as long as the corresponding function is satisfied, it is not correct here. The number, structure and arrangement of the lenses in the third lens group 230 are specifically limited.

In one embodiment, the inner wall of the accommodating space of the bracket 100 is provided with a barrier 110 which is located between the third lens group 230 and the first lens group 210, and the barrier 110 is used to prevent the One mirror group 210 collides with the third mirror group 230 during the movement. The barrier 110 is arranged between the first lens group 210 and the third lens group 230, and can isolate the first lens group 210 and the third lens group 230, so as to effectively avoid the first lens group 210 and the third lens group 230. The lens assembly 230 collides, causing the structure of the lens 1000 to be damaged.

In an embodiment, in the direction along the central axis of the accommodating space, the projection contour of the barrier 110 on the first driving member 310 is enclosed within the contour range of the first driving member 310. It can be understood that, under the above structure, the barrier 110 can also limit the moving range of the first driving member 310, so as to isolate the first lens group 210 and the third lens group 230, effectively avoiding the difference between the lens groups. In addition, the volume of the barrier 110 is small, which reduces the manufacturing cost of the process. At the same time, since the size of the barrier 110 in the direction perpendicular to the central axis of the accommodating space is small, the existence of the barrier 110 will not affect the propagation of light, thereby avoiding its adverse effects on the function of the lens 1000.

It should be noted that when the zoom assembly 200 is installed in the bracket 100, since the space in the bracket 100 is relatively small, it is difficult to adjust the relative position between the lens groups, and it is difficult to adjust the lenses to the same optical axis. , The lens 1000 can adopt a split structure to solve this problem.

In the above-mentioned split structure, the first lens group 210 and the second lens group 220 are separately installed in the sub-brackets, and then the first sub-bracket 11 and the second sub-bracket 12 are docked to form a bracket, and the first lens group 210 and the second mirror group 220 are aligned and installed in a docking manner. Separately install and connect the first lens group 210 and the second lens group 220, which can better avoid operation errors, and make the first lens group 210 and the second lens group 220 align more accurately, so that the first lens group 210 It is precisely located on the same optical axis as the second lens group 220.

It is understandable that the split structure can be transformed in a variety of forms, including but not limited to those provided in the above-mentioned embodiments: combining the first lens group 210 and the first sub-bracket 11 with the second lens group 220 and the second sub-bracket 11 The structure in which the bracket 12 is separated; it can also be a structure in which the first mirror group 210 and the first sub-bracket 11 are separated from the third mirror group 230 and the third sub-bracket 13 (as shown in FIG. 8); and the first mirror The group 210 and the first sub-support 11, the second mirror group 220 and the second support 12, the third mirror group 230 and the third support 13 are separated from each other independently (as shown in FIG. 9).
