[0030] Reference below Figures 1 to 5 A camera module 100 according to the present invention is described.

[0031] like Figures 1 to 3 As shown, the camera module 100 according to the first embodiment of the present invention includes: a lens module 110, an elastic carrier 120, a base 130 and an electromagnetic driving device.

[0032] The elastic carrier 120 includes a first connecting portion 121, a frame portion 122, a second connecting portion 123, a first torsion arm 124 and a second torsion arm 125. The first connecting portion 121 is arranged on the inner side of the frame portion 122, and the second connecting portion 123 is arranged on the outer side of the frame portion 122. The first connecting portion 121 and the frame portion 122 are connected through the first torsion arm 124, and the second connecting portion 123 and the frame portion 122 are connected through the second torsion arm 125. The lens module 110 is installed on the first connecting portion 121, and the lens module 110 can rotate around the first torsion arm 124 or the second torsion arm 125; a ball 133 is arranged on the base 130, and the ball 133 is arranged below the first connecting portion 121 and is used to support the first connecting portion 121; the electromagnetic driving device is arranged at the bottom of the lens module 110, and is used to drive the lens module 110 to rotate around the first torsion arm 124 and / or the second torsion arm 125.

[0033] Specifically, the electromagnetic drive device is a VCM motor, the first connection part 121 is connected to the frame part 122 through the first torsion arm 124, the second connection part 123 is connected to the frame part 122 through the second torsion arm 125, and the first connection part 121 is supported on the ball 133 and connected to the base 130, and the second connection part 123 can be fixedly installed on the base 130, so that when the first torsion arm 124 and / or the second torsion arm 125 are twisted, the lens module 110 installed on the first connection part 121 can rotate. The electromagnetic drive device is arranged between the elastic carrier 120 and the base 130. During handheld shooting, the electromagnetic drive device drives the lens module 110 to rotate to the side opposite to the shaking direction, which plays a role in compensating for the displacement of the camera module 100 caused by shaking during shooting, thereby improving the anti-shake performance of the camera module 100 and improving the quality of the photos taken by the camera module 100.

[0034] In some embodiments of the present invention, two first torsion arms 124 are provided, and the two first torsion arms 124 are arranged opposite to each other and located on both sides of the first connecting portion 121. Figure 5 As shown, two first torsion arms 124 are provided, and the two first torsion arms 124 are relatively provided on both sides of the first connection portion 121. Specifically, the first torsion arms 124 are provided in the Y-axis direction of the first connection portion 121. By providing two first torsion arms 124 with opposite positions on both sides of the first connection portion 121, when the electromagnetic driving device drives the lens module 110 installed on the first connection portion 121 to rotate, the first torsion arms 124 are twisted, and the lens module 110 can rotate around the Y-axis direction.

[0035] In some embodiments of the present invention, two second torsion arms 125 are provided. The two first torsion arms 124 are oppositely arranged and located on both sides of the frame portion 122. The first torsion arm 124 and the second torsion arm 125 are perpendicularly arranged to each other in the horizontal plane. For example, as Figure 5 shown, two second torsion arms 125 are provided.

The first torsion arm 124 and the second torsion arm 125 are perpendicularly arranged to each other in the horizontal plane. Specifically, the second torsion arms 125 are arranged in the X-axis direction of the frame portion 122. By providing two second torsion arms 125 with opposite positions in the X-axis direction of the frame portion 122, during the process of the electromagnetic driving device driving the lens module 110 to rotate, the second torsion arms 125 generate torsion, so that the lens module 110 can also rotate around the X-axis direction.

[0036] In some embodiments of the present invention, a first connecting member 131 is provided on the base 130, and a second connecting member 132 is provided on the first connecting portion 121. Both the first connecting member 131 and the second connecting member 132 are arranged in a "Ji" shape. The openings of the first connecting member 131 and the second connecting member 132 are oppositely arranged. The elastic carrier 120 is arranged on the base 130 through the first connecting member 131 and the second connecting member 132. A gap is left between the first connecting member 131 and the second connecting member 132 so that the second connecting member 132 can rotate as the elastic carrier 120 rotates. For example, as Figures 2 to 4 shown, a first connecting member 131 is provided on the base 130, and a second connecting member 132 is provided on the first connecting portion 121. Both the first connecting member 131 and the second connecting member 132 are arranged in a "Ji" shape. The openings of the first connecting member 131 and the second connecting member 132 are oppositely arranged. The elastic carrier 120 is arranged on the base 130 through the first connecting member 131 and the second connecting member 132. A gap is left between the first connecting member 131 and the second connecting member 132. Specifically, by arranging the openings of the first connecting member 131 and the second connecting member 132 oppositely, the ball 133 is arranged on the first connecting member 131. The ball 133 is used to support the first connecting portion 121 and will not affect the rotation of the first connecting portion 121 and the lens module 110; a gap is left between the first connecting member 131 and the second connecting member 132, so that the second connecting member 132 can rotate as the elastic carrier 120 rotates, which is convenient for the electromagnetic driving device to drive the lens module 110 to rotate in the direction opposite to the jitter and improves the anti-shake performance.

[0037] In some embodiments of the present invention, the bottom of the ball 133 is fixedly installed on the first connecting member 131.

Specifically, a mounting hole is provided on the first connecting member 131, and the bottom of the ball 133 is fixedly mounted on the first connecting member 131, thereby limiting the movement of the ball 133 on the first connecting member 131, ensuring that the ball 133 can support the first connecting portion 121 and the lens module 110, and will not affect the rotation of the first connecting portion 121 and the lens module 110.

Among the four coils 151, two adjacent coils 151 are installed perpendicularly to each other on the base 130, and the positions of the four coils 151 and the magnetic body 152 are opposite. Specifically, by arranging the four coils 151 and the magnetic body 152 oppositely, after power is turned on, the base 130 and the elastic carrier 120 can be attracted or repelled from each other through the attractive force or repulsive force between the coils 151 and the magnetic body 152. Two coils 151 are arranged along the Y-axis direction, and the force between one coil 151 and the magnetic body 152 is an attractive force, and the force between the other coil 151 and the magnetic body 152 is a repulsive force, so that the lens module 110 rotates around the X-axis direction, that is, it rotates around the second torsion arm 125; two coils 151 are arranged along the X-axis direction, and the force between one coil 151 and the magnetic body 152 is an attractive force, and the force between the other coil 151 and the magnetic body 152 is a repulsive force, so that the lens module 110 rotates around the Y-axis direction, that is, it rotates around the first torsion arm 124.

Figure 2 As shown, the flexible circuit is disposed between the base and the coil 151. Specifically, the flexible circuit board 153 mainly energizes the coil 151, so that the energized coil 151 and the magnetic body 152 have a magnetic force of mutual attraction or mutual repulsion, so as to drive the lens module 110 to rotate, so that the lens module 110 compensates for the position deviation caused by shaking.

[0040] In some embodiments of the present invention, a plurality of angle detection members 160 are further included. The angle detection members 160 are disposed in the coil 151 and are used to detect the rotation angle of the lens module 110.

Specifically, the angle detection member 160 is a Hall device, and two Hall devices are provided, and the Hall devices are respectively provided on any two adjacent coils 151. Under the action of the Hall device and the magnetic body 152, the magnetic changes of the coil 151 on the Y axis and the coil 151 on the X axis are respectively detected, and the force between the coil 151 and the magnetic body 152 is controlled according to the magnetic changes, so as to adjust the rotation direction of the lens module 110, so that the lens module 110 moves in the direction opposite to the shaking direction, thereby improving the anti-shake performance of the camera module 100.

[0041] In some embodiments of the present invention, a housing 140 is further included.
