Description

Technical Field

[0001] The present invention relates to the technical field of camera modules, and in particular to a camera module and a digital device. Background Art

[0002] Currently, most mobile devices, such as cell phones and tablets, are equipped with camera modules. These modules convert optical and electrical signals, recording and storing image information, enabling photography and video recording. Compared to traditional camera systems, cell phone camera modules (CCMs) are widely used in a variety of next-generation portable camera devices due to their advantages such as miniaturization, low power consumption, low cost, and high image quality.

[0003] Currently, the structure of a camera module includes a lens unit, a voice coil motor (VCM), an infrared cutoff filter, an image sensor, a flexible printed circuit board (FPC) or printed circuit board (PCB), and a connector for connecting to the mobile phone motherboard. The VCM is used to implement the lens unit's autofocus function and typically includes a magnet and coil. During camera module operation, current is first applied to the coil. The energized coil cuts through magnetic flux lines in a magnetic field, generating electromagnetic force. This electromagnetic force moves the coil or magnet, thereby driving the lens unit connected to the VCM, adjusting the camera module's image and object distances to produce clear images. A Hall effect sensor is often also included in the VCM. This Hall effect sensor measures changes in the VCM's magnetic field and determines the position of the coil or magnet based on these changes, thus achieving closed-loop control of the VCM. The autofocus function in mobile phone cameras is most commonly performed entirely by the entire driver.

[0004] With the rapid development of the smartphone industry, people's expectations for mobile phone camera imaging are also gradually increasing. Focal length and zoom range are a key factor affecting mobile phone camera imaging quality. This requires voice coil motors to have a long driving stroke.

The carrier embedded conductive block 211 is embedded in the inner wall of the support component, contacting the metal ball. The carrier embedded conductive block 211 (positive carrier embedded conductive block 2111 and negative carrier embedded conductive block 2112) has two flat surfaces, each parallel to the optical axis and tangential to the metal ball.

[0062] The base 100 further includes a conductive wire embedding layer 108 , which is embedded in the base 100 , connected to the conductive sheet 130 , and connected to the focus control chip of the camera module via a PCB circuit on the circuit board 102 .

The conductive wire embedding layer 108 is welded to the first connecting portion 31. The second connecting portion 32 is inserted into the first retaining portion 11 and contacts the metal ball 10 in the second retaining portion 12. In this embodiment, the first connecting portion 31 and the second connecting portion 32 are connected to form a right angle. The first connecting portion 31 is provided with a positioning hole 30, which is positioned relative to the base boss, and the conductive wire embedding layer 108 is exposed between the positioning hole 30 and the second connecting portion. In other embodiments, the first connecting portion 31 and the second connecting portion 32 can have other angles or be connected to a smooth surface.

[0065] Specific, combined Figures 1 to 3 ,refer to Figure 6 As shown, in this embodiment, the support assembly 101 further includes a third latching position 13, and the fixing unit further includes an iron shell assembly 300, and the iron shell assembly 300 includes:

[0066] An outer wall 302 and a snap-fit ​​component 301 connected to the outer wall;

[0067] The outer wall 302 is arranged corresponding to the periphery of the base 100 and is suitable for accommodating the mobile unit 200 therein;

[0068] The buckle component 301 is adapted to correspond to the support assembly 101 and is installed at the third locking position 13 , thereby enhancing the support strength of the support assembly.

[0069] In summary, if Figures 2 to 6 As shown, the positive and negative electrodes of the coil body 212 respectively form a conductive path through the carrier embedded conductive block 211, the metal ball 10, the conductive sheet 130, the conductive wire buried layer 108 and the positive and negative electrodes of the focus control chip of the camera module.

[0070] Based on the above settings, the conductive path provided in the camera module provided in this embodiment, through the structure and position setting of the carrier embedded conductive block 211, metal ball 10, conductive sheet 130, and conductive wire buried layer 108, can ensure that the carrier component can continuously and stably provide current to the coil when it is along the optical axis direction without hindering the movement of the carrier component.

[0071] Furthermore, by embedding the conductive block 211 , the metal ball 10 , and the conductive sheet 130 in the carrier, it is ensured that the carrier assembly can obtain a continuous and stable current even in a sufficiently long movement stroke.

[0072] Furthermore, preferably, the material of the carrier embedded conductive block 211, the conductive sheet 130 and the conductive line buried layer 108 is a conductive metal, which may be copper in this embodiment.

[0073] Furthermore, preferably, in this embodiment, the metal ball 10 is a steel ball, because steel has suitable hardness and conductivity, and the rolling friction coefficient of the steel ball is small, which can reduce the resistance of the moving parts.

[0074] Furthermore, preferably, in this embodiment, the surface of the metal ball 10 is plated with gold or silver. Preferably, in this embodiment, the surface of the metal ball 10 is also coated with conductive grease mixed with carbon powder or silver powder.

[0075] Furthermore, preferably, in this embodiment, each conductive sheet corresponds to at least one metal ball, preferably 1 to 4 metal balls. In this way, the stability of the dynamic mode power supply can be ensured within a longer travel range.

[0078] Thus, when the bottom of the movable unit 200 is subjected to a force directed to one side, the sub-elastic component 34 of the second conductive sheet 132 generates a clamping force due to the compression and deformation of the metal ball 10, ensuring that the movable unit 200 does not separate from the ball during movement, ensuring reliable electrical conduction. Furthermore, the rebound force of the sub-elastic component 34 keeps the movement direction of the lens unit 600 aligned with the optical axis.

[0079] Furthermore, the second conductive pieces 132 corresponding to the positive electrode carrier embedded in the conductive block 2111 and the negative electrode carrier embedded in the conductive block 2112 are located on the same side of the base 100. The resultant force generated by the two second conductive pieces 132 on the same side on the mobile unit 200 is perpendicular to the optical axis direction and parallel to the resultant force generated by the elastic component 502 on the mobile unit 200, so as to keep the mobile unit 200 stable during movement.

[0080] Continue to combine Figure 1 ,refer to Figures 7 to 10 As shown, preferably, the fixing unit also includes: a dustproof film and a supporting film structure; the supporting film structure is located between the iron shell assembly and the lens ring, and is fixedly connected to the iron shell assembly; the dustproof film connects the upper part of the lens and the supporting film structure to isolate the inside and outside of the camera module.

When the lens unit 600 is subjected to force toward one side, the rebound force of the elastic component 502 returns it to its original position to keep the movement direction of the lens unit 600 consistent with the direction of the optical axis.

[0083] The elastic component includes an elastic open ring 502 with an opening A. The bearing part includes an inner ring wall 532, an outer ring wall 531, and an annular ridge 533 located between the inner ring wall 532 and the outer ring wall 531.

[0086] The metal ball 10 is a steel ball. The friction between the steel ball and the moving part is rolling friction, and the friction coefficient is small, which can make the moving part move more smoothly.

[0087] The surface of the metal ball 10 is plated with gold or silver. This can increase the conductivity of the metal ball.
