AI Technical Summary
The complexity of the camera driving module in portable optical products leads to difficulties in assembly and low product yield due to the integration of various functions and the need for precise assembly.
The imaging device is composed of three independent modules: a lens module, a focus driving module, and an anti-shake driving module. Each module is assembled separately before being combined, simplifying the assembly process and improving yield. The focus driving module uses a lens barrel, focus coil, focus magnetic steel, and circuit board to achieve focus, while the anti-shake driving module uses an image sensor, anti-shake coil, anti-shake magnetic steel, and planar circuit board to provide anti-shake functionality.
This modular design simplifies the assembly process, enhances product yield, and ensures effective focus and anti-shake performance, thereby guaranteeing high-quality images.

[0002] At present, the optical systems of portable optical products commonly found on the market, such as digital cameras, video cameras, and mobile phones, are composed of an optical lens module and a camera driving module.

For example, shaking (shaking) of the device due to hand-holding, vehicle driving, and external environmental factors can cause problems such as not being able to obtain clear images or blurred images. Therefore, the camera driving module often has an anti-shake function. However, since various functions are integrated, the structure of the camera driving module is relatively complex, and since it is assembled from many parts, the assembly process of the camera driving module is also relatively complex, and even a little carelessness can affect the product yield and lead to improper assembly of the portable optical product.

The anti-shake driving module 30 includes an image sensor 31, an anti-shake coil 32, an anti-shake magnetic steel 33, and a second circuit board 34, in which the anti-shake coil 32 and the anti-shake magnetic steel 33 are provided corresponding to each other, the second circuit board 34 is planar, and the second circuit board 34 and the anti-shake coil 32 are electrically connected, and the second circuit board 34 is further electrically connected to the image sensor 31. When the anti-shake coil 32 is energized, a magnetic force generated between the anti-shake coil 32 and the anti-shake magnetic steel 33 drives the image sensor 31 to move around the optical axis relative to the lens module 10, or drives the image sensor 31 to move in a direction perpendicular to the optical axis relative to the lens module 10.
[0019] In this embodiment, as shown in FIG. 1 and FIG. 4, the lens module 10, the focus driving module 20, and the anti-shake driving module 30 are three independent modules. When assembling, each module is assembled separately, and then the three modules are combined, so that the assembly is easy and the product yield rate can be effectively improved. In addition, the focus driving module 20 can realize the focus effect by driving the lens barrel 21 to move along the optical axis direction of the lens module 10 in the first bracket 22.

The second circuit board 34 includes a circuit board body 341 and a circuit board fixing part 342, and the circuit board fixing part 342 is elastically connected to the outside of the circuit board body 341, and both the circuit board fixing part 342 and the spring plate fixing part 352 are fixed to the first housing 36. The circuit board body 341 is provided with a recessed through-hole 3411, which corresponds to the image sensor 31. The image sensor 31 is connected in the recessed through-hole 3411 and attached to the spring plate body 351. The anti-shake coil 32 is fixed to the circuit board body 341, and the anti-shake magnetic steel 33 is fixed to the first housing 36.
[0023] In this embodiment, the image sensor 31 is attached later and bonded to the spring plate body 351. In order to facilitate the attachment of the image sensor 31 later, the circuit board body 341 is provided with a recessed through-hole 3411, and the circuit board body 341 is made hollow, so that the image sensor 31 can be recessed as far as possible. In one example, the spring plate body 351 is formed with a recessed surface 3511, which is lower than the surface of the spring plate body 351. The recessed surface 3511 is formed by performing a half-etching process on the surface of the spring plate body 351, and the image sensor 31 is bonded to the recessed surface 3511 of the spring plate body 351.
[0024] In this embodiment, the anti-shake driving module 30 is flat and has a structure in which the second circuit board 34 and the spring plate 35 are combined, thereby effectively reducing the thickness of the anti-shake driving module 30 and effectively supporting the image sensor 31, and the module has a small volume and a stable structure.
