[0037] In some embodiments of the present invention, a boss 162 is provided on the first mounting plate 161.

The bottom of the ball 133 is fixedly mounted on the first connecting member 131, and the first mounting plate 161 rotates with the ball 133 as the rotation center. Specifically, by providing a boss 162 on the first mounting plate 161 and the center of the boss 162 being recessed inward, the ball 133 can be disposed in the recess of the boss 162, so that the ball 133 is used to support the first mounting plate 161. The second connecting portion 123 can be fixedly mounted on the base 130, so that the lens module 110 can rotate around the first torsion arm 124 and / or the second torsion arm 125.
[0038] In some embodiments of the present invention, the first electromagnetic driving device includes a first coil 151 and a first magnetic body 152. The first magnetic body 152 is disposed on the first vertical portion, and the first coil 151 is disposed opposite to the first magnetic body 152.

Specifically, since the lens module 110 is arranged on the first horizontal portion, and the first vertical portion is connected to the side of the lens module 110, the first magnetic body 152 is connected to the lens module 110 through the first mounting plate 161. The first electromagnetic driving device is arranged in the X-axis direction of the first vertical portion, and the positive and negative poles of the first magnetic body 152 are distributed in the vertical direction, so that after power is turned on, when the first magnetic body 152 and the first coil 151 generate mutual attraction or mutual repulsion in the vertical direction, the lens module 110 can be driven to rotate around the Y-axis.
[0039] In some embodiments of the present invention, the second electromagnetic driving device includes a second coil 153 and a second magnetic body 154. The second magnetic body 154 is disposed on the first vertical portion, and the second magnetic body 154 is disposed adjacent to the first magnetic body 152.

Specifically, since the lens module 110 is arranged on the first horizontal portion, and the first vertical portion is connected to the side of the lens module 110, the second magnetic body 154 is connected to the lens module 110 through the first mounting plate 161. The second electromagnetic driving device is arranged in the Y-axis direction of the first vertical portion, and the positive and negative poles of the second magnetic body 154 are distributed in the vertical direction, so that after power is turned on, the second magnetic body 154 and the second coil 153 can generate mutual attraction or mutual repulsion in the vertical direction, driving the lens module 110 to rotate around the X-axis.
[0040] In some embodiments of the present invention, the third electromagnetic driving device includes a third coil 155 and a third magnetic body 156. The third magnetic body 156 is disposed on the first vertical portion, and the third magnetic body 156 is disposed adjacent to the second magnetic body 154. The third magnetic body 156 and the third coil 155 are disposed opposite to each other. The third electromagnetic driving device is used to drive the lens module 110 to rotate around the Z axis. For example, Figures 2 to 4As shown, the positive and negative poles of the third magnetic body 156 are distributed in the horizontal direction and are arranged on the first vertical portion. The third magnetic body 156 is arranged adjacent to the second magnetic body 154, and the third magnetic body 156 is arranged opposite to the third coil 155. Specifically, since the lens module 110 is arranged on the first horizontal portion, and the first vertical portion is connected to the side of the lens module 110, the third magnetic body 156 is connected to the lens module 110 through the first mounting plate 161. Since the positive and negative poles of the third magnetic body 156 are distributed in the horizontal direction, after power is turned on, the third magnetic body 156 and the third coil 155 can generate mutual attraction or mutual repulsion in the horizontal direction, driving the lens module 110 to rotate around the Z axis.
[0041] In some embodiments of the present invention, a second mounting plate 163 is further included. The second mounting plate 163 includes a second vertical portion and a second horizontal portion. The second horizontal portion is mounted on the base 130. The first coil 151, the second coil 153 and the third coil 155 are all disposed on the second vertical portion.

Specifically, by mounting the second horizontal portion on the base 130, after the first coil 151, the second coil 153 and the third coil 155 are mounted on the second vertical portion, the positional relationship between the first coil 151 and the first magnetic body 152, the second coil 153 and the second magnetic body 154, and the third coil 155 and the third magnetic body 156 can be maintained, thereby ensuring that the first electromagnetic driving device, the second electromagnetic driving device and the third electromagnetic driving device can drive the lens module 110 to rotate.
[0042] In some embodiments of the present invention, two first torsion arms 124 and two second torsion arms 125 are provided, the two first torsion arms 124 are arranged opposite to each other and are located on both sides of the frame portion 122, and the two second torsion arms 125 are arranged opposite to each other and are located on both sides of the first connecting portion 121.

Specifically, the first torsion arm 124 is arranged in the X-axis direction of the first connecting portion 121. By arranging two first torsion arms 124 with opposite positions on both sides of the frame 122, when the first electromagnetic driving device drives the lens module 110 to rotate, the first torsion arm 124 is twisted, and the lens module 110 can rotate around the X-axis direction. The second torsion arm 125 is arranged in the Y-axis direction of the frame 122. By arranging two second torsion arms 125 with opposite positions on the Y-axis direction of the frame 122, when the second electromagnetic driving device drives the lens module 110 to rotate, the second torsion arm 125 is twisted, and the lens module 110 can rotate around the Y-axis direction. Since the first torsion arm 124 and the second torsion arm 125 can be bent, the third electromagnetic driving device can drive the lens module 110 to rotate around the Z axis. The lens module 110 can rotate around the X axis, the Y axis and the Z axis at the same time, and has a high degree of freedom. It can compensate for the position deviation caused by shaking from multiple directions, thereby improving the anti-shake performance and imaging effect of the camera module 100.
[0043] The electronic device according to the second embodiment of the present invention includes the camera module 100 according to the first embodiment of the present invention.
[0044] According to the electronic device of the embodiment of the present invention, by adopting the above-mentioned camera module 100, when the camera module 100 of the electronic device is shooting, the anti-shake performance of the camera module 100 can be improved, thereby improving the imaging effect after shooting by the camera module 100.
