The upper spring 16 is also electrically connected to the coil 18. The coil 18 is disposed on the lens assembly 14, and the magnet 20 is disposed on the housing 22, and the magnet 20 and the coil 18 are disposed correspondingly.

[0029] In this drive device, the electrical connection is achieved by electrically connecting the terminal 102 to the upper spring 16, which is electrically connected to the coil 18. The connection process between the terminal 102 and the upper spring 16 can be performed from above the lens assembly 14, providing ample operating space and facilitating operation. Furthermore, since the connection process is performed from above the lens assembly 14, the lower spring 12, lens assembly 14, and housing 22 can be sequentially positioned above the base 10 without the need to flip all components, making operation more convenient and simplifying the assembly process. Furthermore, since the connection process is performed from above the lens assembly 14, a protective film can be added when welding the upper spring 16 to the terminal 102 to prevent contamination of the lens assembly 14 during welding.

[0030] In this embodiment, the base 10 further includes a base 104, within which the terminals 102 are embedded. The base 104 can be formed by plastic injection molding. The terminals 102 are made of a conductive material, such as metal. Specifically, in this embodiment, there are two terminals 102 spaced apart from each other. The base 10 is provided with a first protrusion 106. Each of the four corners of the base 10 is further provided with a corner post 107, each of which is provided with a second protrusion 108.

[0031] In this embodiment, the lower spring 12 is a single unit, with one end fixedly connected to the base 10 and the other end fixedly connected to the lens assembly 14. The lower spring 12 supports the lens assembly 14 and allows the lens assembly 14 to move relative to the base 10. Specifically, the lower spring 12 includes a first inner ring, a first connecting deformable portion, and a first outer ring. The connecting deformable portion is deformable and connected between the first inner ring and the first outer ring. The first outer ring is fixedly connected to the base 10, and the first inner ring is fixedly connected to the lens assembly 14. More specifically, the lower spring 12 is provided with a first engaging hole 122, into which the first boss 106 of the base 10 engages.

[0032] In this embodiment, the lens assembly 14 includes a carrier 142 and a lens 144 fixed to the carrier 142. Specifically, in this embodiment, the carrier 142 and the lens 144 are integrally formed. It is understood that the carrier 142 and the lens 144 may also be separate structures and assembled together during assembly. When the carrier 142 and the lens 144 are integrally formed, the assembly process can be simplified. Specifically, a third protrusion 146 is provided on the carrier 142.

[0033] In this embodiment, one end of the upper spring 16 is fixedly connected to the base 10, and the other end is fixedly connected to the lens assembly 14 to allow the lens assembly 14 to move relative to the base 10.

Connect the other end of the lower spring 12 to the lens assembly 14. Specifically, the coil 18 can be assembled on the lens assembly 14 first, and then the lens assembly 14 is installed on the base 10. Alternatively, the lens assembly 14 can be installed on the base 10 first, and then the coil 18 can be assembled on the lens assembly 14.

[0046] Specifically, the lens assembly 14 includes a carrier 142 and a lens 144 fixed to the carrier 142. Specifically, in this embodiment, the carrier 142 and lens 144 are integrally formed. It will be appreciated that the carrier 142 and lens 144 may also be separate structures and assembled together during assembly. When the carrier 142 and lens 144 are integrally formed, the assembly process can be simplified. Specifically, a third protrusion 146 is provided on the carrier 142. A coil 18 is provided on the carrier 142. In this embodiment, there are two coils 18. More specifically, the two coils 18 are provided on opposite sides of the lens assembly 14. This eliminates the need for coils 18 on the other two sides of the lens assembly 14, reducing the overall dimensions of the drive device on those other two sides and facilitating miniaturization of the drive device. Of course, there may also be one, three, or more coils 18.

[0050] In step S17, the steps of electrically connecting the upper spring 16 to the terminal 102 and the coil 18 are specifically as follows: electrically connecting the two second upper spring portions 164 to the two terminals 102, specifically by welding them together; electrically connecting one end of the two coils 18 to the two second upper spring portions 164, and electrically connecting the other ends of the two coils 18 to the first upper spring portion 162. In this way, the two coils 18 are connected in series, and current flows into one terminal 102, then passes through one second upper spring portion 164, the first upper spring portion 162, the other second upper spring portion 164, and finally flows out through the other terminal 102. When there is one coil 18, the upper spring 16 can be divided into two parts, and the two parts of the upper spring 16 are electrically connected to the two ends of the coil 18 respectively. When there are three or more coils 18, this is also possible. The circuit connection relationship can be adjusted accordingly, and no further details are given here.

[0051] More specifically, the upper spring 16 includes a second inner ring, a second connection deformable portion, and a second outer ring.

The housing 22 can be fixedly connected to the base 10. The terminal 102 is electrically connected to the upper spring 16 through the gap between the lens assembly 14 and the housing 22.

[0054] Using this drive device assembly method, the electrical connection is achieved through the upper spring 16 by electrically connecting the terminal 102 to the upper spring 16, which is electrically connected to the coil 18. The connection process between the terminal 102 and the upper spring 16 can be performed on top of the lens assembly 14, providing ample operating space and facilitating operation. Furthermore, since the process is performed on top of the lens assembly 14, the lower spring 12, lens assembly 14, and housing 22 can be sequentially positioned above the base 10 without the need to flip all components, making operation more convenient and simplifying the assembly process. Furthermore, since the process is performed on top of the lens assembly 14, a protective film can be added when welding the upper spring 16 to the terminal 102 to prevent contamination of the lens assembly 14 during welding.
