Description

Technical Field

[0001] The utility model relates to the field of camera modules, and in particular to an ultra-angle anti-shake mobile phone camera module. Background Art

[0002] There are ultra-wide-angle cameras in the prior art. The advantage of ultra-wide-angle cameras is that they can simultaneously shoot objects at ultra-wide angles and can contain a large amount of image information. However, at the same time, wide-angle cameras will also produce obvious image distortion, resulting in obvious image distortion. When we usually use mobile phones to take pictures, if we want to take pictures at certain special angles, we often need people to hold the phone and rotate it at various angles. Some angles may be tricky and difficult to shoot, or shaking may occur during shooting, resulting in poor image quality. Therefore, if a mobile phone camera module that can switch shooting angles can be provided, it will be possible to achieve ultra-angle shooting while ensuring the quality of the captured image. Utility Model Content

[0003] The utility model aims to provide a mobile phone camera module with ultra-angle anti-shake function, so as to provide a mobile phone camera module capable of switching shooting angles.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an ultra-angle anti-shake mobile phone camera module, including a sliding group and a lens group, the sliding group includes a sliding plate and a bottom plate, the lens group is fixed on the sliding plate, the cross-sectional shape of the sliding plate is an inverted trapezoid, the cross-sectional shape of the bottom plate is the same as the sliding plate, the sliding plate and the bottom plate are provided with sliding grooves on the opposite surfaces, a plurality of ball bearings are provided in the sliding grooves for sliding, the sliding plate and the bottom plate can slide relative to each other through the ball bearings, a magnet portion is embedded in the bottom of the sliding plate, and a coil portion opposite to the magnet portion is provided at the bottom of the bottom plate.

[0005] The beneficial effects of this program are:

[0006] When the coil part is energized, electromagnetic induction is generated, causing the magnet part to slide relative to the coil part, and the magnet part can drive the sliding plate to slide relative to the bottom plate. The sliding plate and the bottom plate have sliding grooves on their opposite surfaces, and a plurality of balls are provided in the sliding grooves for sliding. Therefore, the sliding plate will slide along the direction of the sliding grooves. Setting the sliding grooves can ensure the smooth sliding of the sliding plate while making it slide along the set track, preventing shaking and making the sliding process smoother, thereby ensuring a clear and complete picture.

[0007] Moreover, the cross-sectional shape of the sliding plate in the present technical solution is an inverted trapezoid, and the lens group is fixed on the sliding plate, and the cross-sectional shape of the bottom plate is the same as that of the sliding plate. When the sliding plate slides to the inclined surface of the inverted trapezoid, it will tilt, which can drive the lens to rotate to a certain angle. Through the above arrangement, the shooting angle of the lens can be switched, so that the user can achieve multi-angle shooting without turning the mobile phone, and at the same time will not cause excessive distortion of the picture.

[0008] Preferably, as an improvement, the lens group includes a protective shell, a lens, a sensor and a first flexible circuit board in sequence, one end of the head of the first flexible circuit board is a chip part, the sensor is fixed on the chip part, the lens is fixedly mounted on the protective shell, and an IR sheet is also fixedly provided between the sensor and the lens.

[0009] The beneficial effects are: the IR sheet can filter out infrared light, reduce or eliminate image distortion caused by infrared light, and improve the color reproduction of the image. The sensor is located in a protective shell, which helps protect the sensor from the influence of the external environment, such as dust, water vapor or other impurities. The compact structure of the internal components of the lens group helps the entire module to be compact, meeting the needs of mobile phones for thinness and lightness.

[0010] Preferably, as an improvement, the coil portion includes a second flexible circuit board, the magnet portion includes a plurality of magnet groups, the flexible circuit board is provided with coils having the same number as the magnet groups, each coil is opposite to a magnet group, and the coils are electrically connected to the second flexible circuit board.

[0011] The beneficial effect is that the coil on the second flexible circuit board is connected to the magnet group, and the magnetic field is generated in the coil through the change of the current, which can control the sliding direction of the magnet group and make the sliding plate float relative to the bottom plate to achieve precise control of the magnet group, thereby accurately adjusting the position of the sliding plate to achieve ultra-wide-angle anti-shake and shooting angle switching functions. Through precise electromagnetic induction control, highly controllable movement of the sliding plate can be achieved. This helps to more effectively combat the shake caused by handheld shooting during shooting and improve the performance of the anti-shake system.

[0013] The beneficial effect is: through the above-mentioned setting, the first flexible circuit board is electrically connected to the second flexible circuit board, and the picture information obtained by the sensor in the first flexible circuit board and the current information of the second flexible circuit board are transmitted to the processor of the mobile phone together, so that the user can further adjust the angle according to the picture information to achieve switching between multiple angles.

[0014] Preferably, as an improvement, the sliding plate includes a middle transverse plate portion and inclined plate portions at both ends.

[0015] The beneficial effect is that the above arrangement enables the sliding plate to slide on the transverse plate portion and the inclined plate portion, and when sliding on the inclined plate portion, it can rotate to produce an angle change.

[0016] Preferably, as an improvement, the slide groove is V-shaped.

[0017] The beneficial effect is that the slide groove is set to be V-shaped, and the ball bearings are placed on the V-shaped slide groove to play the role of automatic correction and guidance, thereby ensuring the sliding track of the sliding plate and ensuring the smoothness of the sliding.

[0018] Preferably, as an improvement, it further comprises a shell portion, which comprises an upper shell and a lower shell.

[0019] The beneficial effect is that the internal mechanism of the module can be protected by arranging the upper shell and the shell.

[0020] Preferably, as an improvement, an iron magnet is attached to the bottom of the second flexible circuit board.

[0021] The beneficial effects are: on the one hand, attaching the magnetic sheet can increase the strength of the bottom of the second flexible circuit board. Since the magnet group is magnetic, the magnetic sheet can create a force that pulls the sliding plate and the bottom plate closer to each other, preventing the sliding plate from leaving the ball track when sliding quickly, and ensuring that the sliding plate always slides against the ball.

[0022] Preferably, as an improvement, a flexible buffer sheet is further provided between the IR sheet and the housing.

[0023] The beneficial effect is that the IR sheet and the sensor can be protected.

[0024] Preferably, as an improvement, the number of magnet groups is 6, and two magnet groups are symmetrically embedded along the slide groove at the bottom of the transverse plate portion and the two inclined plate portions.

[0025] The beneficial effect is: through the above-mentioned arrangement, a magnet group is provided on the transverse plate portion and the inclined plate portion, which enables the sliding plate to slide onto the inclined plate portion, and the magnet group is symmetrically embedded along the slide groove to ensure that when the sliding plate is in contact with the bottom plate only through the ball bearings at the bottom, the forces on both sides of the sliding plate are balanced, thereby preventing it from tilting to one side.

The sliding group includes a sliding plate 1 and a bottom plate 2. The lens group is fixed on the sliding plate 1 by glue. The cross-sectional shape of the sliding plate 1 is an inverted trapezoid, that is, the sliding plate 1 includes a middle horizontal plate part and an inclined plate part at both ends. The cross-sectional shape of the bottom plate 2 is the same as that of the sliding plate 1. The sliding plate 1 and the bottom plate 2 are both provided with a slide groove 3 on the opposite surfaces. The slide groove 3 is V-shaped. A plurality of balls 4 are provided in the slide groove 3. The sliding plate 1 and the bottom plate 2 can slide relative to each other through the balls 4. The slide groove 3 is set to be V-shaped.

The magnet groups 6 are provided in the horizontal plate portion and the inclined plate portion, so that the sliding plate 1 can slide onto the inclined plate portion, and the magnet groups 6 are symmetrically embedded along the slide groove 3 to ensure that when the sliding plate 1 contacts the bottom plate 2 only through the ball bearings 4 at the bottom, the forces on both sides of the sliding plate 1 are balanced to prevent it from tilting to one side.

[0033] The lens group includes a protective shell 8, a lens 9, a sensor 10 and a first flexible circuit board 11 in sequence. One end of the head of the first flexible circuit board 11 is a chip part 12. The sensor 10 is fixed on the chip part 12. The lens 9 is fixedly mounted on the protective shell 8. An IR sheet 13 is fixedly arranged between the sensor 10 and the lens 9. The IR sheet 13 can filter out infrared light, reduce or eliminate image distortion caused by infrared light, and improve the color reproduction of the image. A flexible buffer sheet 14 is also arranged between the IR sheet 13 and the shell to protect the IR sheet 13 and the sensor 10. The sensor 10 is located in the protective shell 8, which helps to protect the sensor 10 from the external environment.

The sliding plate 1 and the bottom plate 2 have sliding grooves 3 on their opposing surfaces, and a plurality of balls 4 are provided in the sliding grooves 3 for sliding. Therefore, the sliding plate 1 will slide along the direction of the sliding grooves 3. The provision of the sliding grooves 3 can ensure the smoothness of the sliding plate 1 while making it slide along the set track, preventing shaking and making the sliding process smoother, thereby ensuring a clear and complete picture.
