[0049] Figure 1 is a structural schematic diagram of a camera module according to an exemplary embodiment, Figure 2 is an exploded schematic diagram of a camera module according to an exemplary embodiment. As shown in Figure 1 and Figure 2 The camera module includes a fixing seat 1, a lens 2 and a carrier 3, wherein the fixing seat 1 is the appearance structure of the camera module, such as the shell, and the relative fixation between the camera module and the internal parts of the electronic device can be realized through the fixing seat 1, and the camera module is stably arranged in the electronic device. The carrier 3 is fixedly connected with the lens 2, and in the direction of the optical axis of the lens 2, the carrier 3 is movably arranged between the fixing seat 1. In this way, when the carrier 3 moves relative to the fixing seat 1 in the direction of the optical axis, the lens 2 can be moved in the direction of the optical axis, and the distance between the lens 2 and the image sensor located on the light-emitting side of the lens 2 is adjusted to realize focusing.

[0050] For example, the carrier 3 can include a carrier cavity 31, and the lens 2 can be fixedly arranged in the carrier cavity 31, such as the lens 2 can be assembled into the carrier cavity 31 from the opening end of the carrier cavity 31, and automatically buckled with the buckle in the carrier cavity 31, thereby realizing the fixed arrangement of the lens 2; or the camera module further includes a limiting plate 7, which is detachably connected with the carrier 3. When the lens 2 needs to be assembled, the limiting plate 7 is detached, and after the lens 2 is assembled, the limiting plate 7 is connected with the carrier 3 to limit the lens 2 in the carrier cavity 31 through the limiting plate 7. Of course, in other embodiments, the limiting plate 7 can also be movably connected with the carrier 3, so as to realize the opening and closing of the carrier cavity 31 through the movement of the limiting plate 7 relative to the carrier 3.

[0051] Further, the camera module further comprises a first ball group 4, a second ball group 5 and a third ball group 6, the first ball group 4, the second ball group 5 and the third ball group 6 are arranged between the carrier 3 and the fixing base 1, the centers of the first ball group 4, the second ball group 5 and the third ball group 6 are located in the same plane parallel to the optical axis direction of the lens 2, so that the three ball groups are located at the same height and support the carrier 3 to the same extent. The first ball group 4, the second ball group 5 and the third ball group 6 each comprise at least one ball, and the centers of the first ball group 4, the second ball group 5 and the third ball group 6 can serve as the vertices of a triangle, that is, the first ball group 4, the second ball group 5 and the third ball group 6 are not arranged on the same straight line. By using the stability of the triangle, the structural stability of the camera module can be improved, and the relative movement between the carrier 3 and the fixing base 1 in the optical axis direction is realized by the first ball group 4, the second ball group 5 and the third ball group 6, which is simple in structure, small in rolling friction and conducive to reducing the focusing power consumption.

[0052] Herein, the first ball group 4, the second ball group 5 and the third ball group 6 are taken as an example for description, in other embodiments, the camera module can also comprise four or more ball groups, and the centers of the four or more ball groups can form at least one vertex of a triangle, and the centers of the four or more ball groups are located in the same plane.

[0053] When each ball group comprises a plurality of balls, the plurality of balls are arranged side by side in the optical axis direction of the lens 2, for example Figure 2 As shown, the first ball group 4 and the second ball group 5 each comprise two balls arranged in the optical axis direction of the lens 2, and the third ball group 6 comprises three balls arranged in the optical axis direction of the lens 2, which is conducive to realizing the relative movement between the carrier 3 and the fixing base 1 in the optical axis direction.

[0054] In some embodiments, the fixed seat 1 comprises a mounting cavity 11, and the carrier 3 is arranged in the mounting cavity 11. In order to ensure that the carrier 3 can be pressed on the first, second and third ball groups 4, 5 and 6, the camera module further comprises a first suction member 8 and a second suction member 9. The first suction member 8 is arranged on the bottom surface of the mounting cavity 11, and the second suction member 9 is arranged on the side surface of the carrier 3 facing the bottom surface of the mounting cavity 11. The first suction member 8 and the second suction member 9 can be arranged in an attractive manner within the range of the carrier 3 and the fixed seat 1 in the optical axis direction. In this way, the carrier 3 can be pressed on the ball groups by the attractive force between the first suction member 8 and the second suction member 9, so as to ensure that the carrier 3 and the fixed seat 1 can move relative to each other in the optical axis direction. The first suction member 8 and the second suction member 9 can be the attraction between a magnet and another magnet, or the attraction between a magnet and a metal piece, and the disclosure does not limit this.

[0055] In some embodiments, the camera module further comprises a first electromagnetic assembly 10, which comprises a first coil 101 and a first magnet 102 arranged opposite to each other. One of the first coil 101 and the first magnet 102 can be fixedly arranged relative to the fixed seat 1, and the other one can be fixedly arranged relative to the carrier 3. Through the interaction between the first magnet 102 and the first coil 101, the carrier 3 can be driven to move relative to the fixed seat 1 in the optical axis direction, thereby realizing the auto-focusing function of the camera module.

[0056] Further, the camera module further comprises a position sensor 13 for feeding back an electrical signal about the relative position relationship between the fixed seat 1 and the carrier 3. The number of the position sensor 13 can be one or more. The position sensor can be a Hall sensor, which detects the relative position relationship between the fixed seat 1 and the carrier 3 by detecting the magnetic field strength.

[0057] In the above various embodiments, the camera module further comprises a reflecting member 14 and a bracket 15. The bracket 15 is arranged on the fixed seat 1, and the reflecting member 14 is fixedly arranged on the bracket 15. The light emitting direction of the reflecting member 14 is arranged in parallel with the optical axis direction of the lens 2, so that the light emitted from the reflecting member 14 can enter the lens 2. The bracket 15 and the fixed seat 1 can be fixedly arranged, or the bracket 15 and the fixed seat 1 can have a rotational freedom in at least one direction perpendicular to the optical axis of the lens 2, so as to realize the anti-shake function of the camera module.

[0058] The support 15 and the carrier 3 are arranged in the mounting cavity 11 of the fixing base 1, and the support 15 and the carrier 3 are arranged side by side along the optical axis direction of the lens 2, and the light entering direction of the reflecting component 14 is perpendicular to the optical axis direction of the lens 2, so that the light path direction can be changed through the arrangement of the reflecting component 14, which is beneficial to realize the periscope structure of the camera module and reduce the thickness requirement of the electronic equipment. The camera module can further include a shell 21 fixedly connected with the fixing base 1, so as to protect the support 15 and the carrier 3 arranged in the mounting cavity 11 through the shell 21. The camera module further includes a sealing ring 22 which can be arranged between the lens 2 and the fixing base 1 to realize the sealed connection therebetween.

[0059] In order to realize the relative movement between the support 15 and the fixing base 1, the camera module is configured with an anti-shake function. As shown in Figures 3-6 The support 15 includes a first guide groove 151, and the fixing base 1 includes a second guide groove 12. The reflecting assembly further includes a cross shaft 16 including a first shaft 161 and a second shaft 162 arranged orthogonally, and the first shaft 161 penetrates the first guide groove 151 and is rotationally matched with the first guide groove 151, and the second shaft 162 penetrates the second guide groove 12 and is rotationally matched with the second guide groove 12. The cross shaft 16 realizes the rotational freedom in the first axial direction and the rotational freedom in the second axial direction between the support 15 and the fixing base 1, realizes the rotation of the support 15 in two orthogonal directions, and the movements in the two orthogonal directions are relatively independent and do not interfere with each other; and the second guide groove 12 and the first guide groove 151 have mature groove processing technology and small tolerance, so as to improve the production yield of the reflecting assembly.

[0060] In this embodiment, the first guide groove 151 of the support 15 is recessed inward from one side of the bottom surface of the support 15 toward the mounting cavity 11, and the second guide groove 12 is recessed inward from a part of the surface of the fixing base 1 toward the support 15. The bottom surface of the support 15 is arranged opposite to the bottom surface of the mounting cavity 11, and the first guide groove 151 is recessed inward from the bottom surface of the support 15. The fixing base 1 further includes a fixing block arranged on the bottom surface of the mounting cavity 11, and the second guide groove 12 is recessed inward from the surface of the fixing block, for example, the fixing block can be arranged opposite to the side surface of the support 15, and the surface of the fixing plate away from the bottom surface of the mounting cavity 11 is recessed inward to form the second guide groove 12.

[0061] In some embodiments, the bracket 15 further comprises a limiting groove 152 and at least one protrusion 153 protruding towards the inside of the limiting groove 152, the second rotating shaft 162 passes through the limiting groove 152 and the protrusion 153 is in contact with the second rotating shaft 162 for limiting, so that a relatively stable positional relationship is formed between the second rotating shaft 162 and the bracket 15, that is, a relatively stable positional relationship is formed between the cross rotating shaft 16 and the bracket 15, and subsequently the bracket 15 and the cross rotating shaft 16 can be driven to rotate around the first axis relative to the fixed seat 1. Alternatively, in other embodiments, the limiting groove 152 and the second rotating shaft 162 can be tightly fitted, thereby realizing synchronous rotation of the bracket 15 and the cross rotating shaft 16 relative to the fixed seat 1 around the first axis.

[0062] In the above embodiments, the first guide groove 151 can be a groove structure capable of cooperating with the outer circumferential surface of the first rotating shaft 161. For example, the first guide groove 151 can be a circular groove, or for example, the first guide groove 151 can comprise a first inclined surface 154 and a second inclined surface 155, which are respectively tangent to the first rotating shaft 161, so that the first inclined surface 154 and the second inclined surface 155 are both in line contact, which is beneficial to reduce the frictional force required to be overcome during the rotation of the first rotating shaft 161 relative to the fixed seat 1. Among them, the first inclined surface 154 and the second inclined surface 155 can directly intersect, or be connected through a transition inclined surface or a transition arc surface or a transition bending surface. For another example, the first guide groove 151 can comprise one or more second arc-shaped inner walls, which are tangent to the first rotating shaft 161.

[0063] Similarly, the second guide groove 12 can be a groove structure capable of cooperating with the outer circumferential surface of the second rotating shaft 162. For example, the second guide groove 12 can be a circular groove, or the second guide groove 12 can comprise a first inclined surface 154 and a second inclined surface 155, which are respectively tangent to the second rotating shaft 162, so that the first inclined surface 154 and the second inclined surface 155 are both in line contact, which is beneficial to reduce the frictional force required to be overcome during the rotation of the bracket 15 around the second rotating shaft 162. Among them, the first inclined surface 154 and the second inclined surface 155 can directly intersect, or be connected through a transition inclined surface or a transition arc surface or a transition bending surface. For another example, the second guide groove 12 can comprise one or more first arc-shaped inner walls, which are tangent to the second rotating shaft 162.

[0064] In some embodiments, as Figures 7-9As shown, the camera module further comprises a second electromagnetic assembly 17 and a third electromagnetic assembly 18, the second electromagnetic assembly 17 comprises a second coil 171 and a second magnet 172, the third electromagnetic assembly 18 comprises a third coil 181 and a third magnet 182, the second magnet 172 and the third magnet 182 have the same pole arrangement direction, for example, the pole arrangement direction of the second magnet 172 and the third magnet 182 are both arranged along the up-down direction in the figure, and the S pole is above and the N pole is below. Figure 10 The axial directions of the second coil 171 and the third coil 181 are parallel, and the axial directions of the second coil 171 and the third coil 181 are perpendicular to the pole arrangement directions of the second magnet 172 and the third magnet 182.

[0065] The second coil 171 and the third coil 181 are arranged side by side and located on both sides of the rotation axis of any one of the rotation degrees of freedom of the support 15, when the second magnet 172 and the third magnet 182 are subjected to forces in opposite directions, the support 15 rotates around the rotation axis of any one of the rotation degrees of freedom; when the second magnet 172 and the third magnet 182 are subjected to forces in the same direction, the support 15 rotates around the rotation axis of another rotation degree of freedom perpendicular to the rotation axis of any one of the rotation degrees of freedom.

[0066] For example, taking the support 15 having the rotation degrees of freedom around the rotation axis of the second rotation shaft 162 and the rotation degrees of freedom around the first rotation shaft 161 as an example, the second coil 171 and the third coil 181 are located on both sides of the first rotation shaft 161. As shown in Figure 8 When the second magnet 172 and the third magnet 182 are subjected to forces in the same direction, the support 15 rotates around the axis of the second rotation shaft 162 under the action of the force; as shown in Figure 9 When the second magnet 172 and the third magnet 182 are subjected to forces in opposite directions, the support 15 rotates around the first rotation shaft 161 under the action of the two opposite forces. The direction of the force between the second magnet 172 and the third magnet 182 can be adjusted by adjusting the current direction of the second coil 171 and the third coil 181, and the size of the force can be adjusted by adjusting the current size of the second coil 171 and the third coil 181.
