[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] like Figure 1-3As shown, the present invention relates to an assembled lens module motor, comprising a base bracket 1, a voice coil motor 2, and a lens 3. The voice coil motor 2 is mounted at the top of the base bracket 1, and the lens 3 is detachably and fixedly mounted at the center of the voice coil motor 2. An assembly groove 4 is provided at the center of the base bracket 1, and a photosensitive chip 5 and a driver chip 6 are sequentially and fixedly embedded in the assembly groove 4 from top to bottom. An output interface 7 is fixedly mounted at the bottom of the base bracket 1. Assembly rods 8 are fixedly provided at the four corners of the top of the base bracket 1, and support rod slots 9 are provided at the four corners of the bottom of the voice coil motor 2. The four assembly rods 8 are inserted into the support rod slots 9 and fixedly positioned by a limiting component.

[0019] Specifically, the base bracket 1 and the voice coil motor 2 are connected by an assembly rod 8 and a rod slot 9, and the assembly rod 8 is fixed by a limiting component inside the rod slot 9, which improves the stability of the assembly between the base bracket 1 and the voice coil motor 2 and improves the structural strength of the lens module motor.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention relates to a prefabricated lens module motor, wherein the limiting component includes multiple arc-shaped protrusions 11, and multiple arc-shaped protrusions 11 are equidistantly inserted into one side of the support rod slot 9. Multiple arc-shaped grooves 12 are equidistantly provided on the alignment surface of the assembly support rod 8 and the arc-shaped protrusions 11, and the ends of the multiple arc-shaped protrusions 11 are nested and connected to the corresponding arc-shaped grooves 12.

[0021] The voice coil motor 2 has mounting slots 13 at each of its four corners. A first connecting plate 15 is nested inside one side of the mounting slot 13. The other ends of multiple arc-shaped protrusions 11 extend into the mounting slot 13 and are fixedly connected to the side of the first connecting plate 15.

[0022] Specifically, the arc-shaped protrusion 11 and the arc-shaped groove 12 are nested and fixed, which makes it easy to fix the assembly rod 8 inside the rod slot 9.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, in the assembled lens module motor of this utility model, a second connecting plate 16 is nested and connected to the other side of the mounting groove 13. A reset spring 14 is fixedly installed between the second connecting plate 16 and the first connecting plate 15, and the reset spring 14 is distributed along the four corners of the first connecting plate 16 and the second connecting plate 15.

[0024] A limiting block 10 is fixedly provided on one side of the second connecting plate 16. One end of the limiting block 10 extends through the mounting groove 13 to the assembly point of the voice coil motor 2 and the lens 3. A corrugated groove adapted to the outer surface coil of the lens 3 is opened on the end face of the limiting block 10.

[0025] Specifically, the corrugated groove can cooperate with the coil on the surface of the lens 3 to facilitate the positioning and fixing of the lens 3.

[0026] A suction block 18 is fixedly provided at the center of the other side of the second connecting plate 16. An electromagnetic sheet 17 is provided at the position of the suction block 18 and is fixedly connected to the first connecting plate 15. The electromagnetic sheet 17 is attracted and connected to the suction block 18.

[0027] The attraction force between the electromagnetic plate 17 and the suction block 18 is greater than the sum of the elastic forces of the multiple return springs 14.

[0028] Specifically, the electromagnetic plate 17 and the suction block 18 are attracted by the combination of the return spring 14, which facilitates the control of the movement of the first connecting plate 15 and the second connecting plate 16. The movement of the first connecting plate 15 and the second connecting plate 16 drives the movement of the limiting block 10 and the arc-shaped protrusion 11, which facilitates the fixing and disassembly of the assembly support rod 8.

[0029] In specific implementation, when the lens module motor needs to be assembled, firstly, the power is turned on and the electromagnetic plate 17 is turned on. Through the attraction between the electromagnetic plate 17 and the suction block 18, the first connecting plate 15 and the second connecting plate 16 move towards the center. At this time, the return spring 14 between the first connecting plate 15 and the second connecting plate 16 is in a compressed state. Then, the assembly support rods 8 provided at the four corners of the top of the base bracket 1, which is equipped with the photosensitive chip 5 and the driver chip 6, are manually inserted into the corresponding support rod slots 9. The lens 3 is nested into the center of the voice coil motor 2. Then, the power to the electromagnetic plate 17 is turned off. At this time, the first connecting plate 15 and the second connecting plate 16 move to the sides. The movement of the first connecting plate 15 causes the arc-shaped protrusion 11 to extend and nest with the arc-shaped groove 12. The movement of the second connecting plate 16 drives the limit block 10 to move, so that the corrugated groove on the end face of the limit block 10 abuts and fixes against the coil on the surface of the lens 3, thus completing the assembly of the lens module motor.
