[0130] This disclosure provides a camera module comprising a base, a first rolling element group, a first carrier, a second rolling element group, a second carrier, an optical path deflector, and a first driving body. The first rolling element group is disposed on the base and includes at least three first rolling elements. A virtual circle passes through the center of each first rolling element, and a first axis passes through the center of the virtual circle. The first carrier is connected to the base via the first rolling element group, which is positioned between the base and the first carrier. The first carrier rotates about the first axis. The second rolling element group is disposed on the first carrier and includes at least two second rolling elements. A second axis passes through the center of each second rolling element and is perpendicular to the first axis. The second carrier is connected to the first carrier via the second rolling element group and rotates relative to the first carrier about the second axis. The optical path deflector is fixed to the second carrier and deflects light rays from the first axis to a third axis, which is perpendicular to the second axis. The first driving body includes a first driving magnet and a first driving coil. The first driving magnet is fixed to the first carrier. The first drive coil is fixed to the base, wherein the first drive body drives the first carrier to rotate about the first axis. The second carrier includes an attraction element that attracts the first drive magnet, so that the first carrier and the second carrier simultaneously come into contact with the second rolling element.

[0131] By sharing the first driving magnet with the first driving coil, the number of components used can be reduced, thereby reducing the weight of the camera module, improving driving efficiency, and further guiding the magnetic field to improve the magnetic field distribution in space.

[0132] Specifically, the attraction element can be disposed on the second carrier to prevent changes in the pressure on the second rolling element when the carrier moves. The attraction element can be a metal element that can be attracted by a magnet, such as iron, or a magnet, but this disclosure is not limited thereto. In addition, the drive coil (e.g., the first drive coil) of this disclosure can be further fixed to the circuit board in advance, and the circuit board is fixed to the base to achieve a fixed relationship between the drive coil and the base.

[0133] The first driving magnet is a multi-pole magnet, comprising a first magnetic pole, a second magnetic pole, and a third magnetic pole. The first and second magnetic poles are arranged adjacent to each other and face the first driving coil. The third magnetic pole is arranged correspondingly to the attraction element, and is further away from the first driving coil than the first and second magnetic poles, thereby preventing the magnetic field of the first driving coil from affecting the attraction element. Specifically, the first driving magnet can be configured as a multi-pole magnet during the magnetization process, or multiple magnets can be bonded together to form a multi-pole magnetic circuit configuration.

[0134] The first driving coil is farther away from the optical path reversing element than the first driving magnet, and the attracting element is closer to the optical path reversing element than the first driving magnet. This reduces magnetic field interference between the first driving coil and the attracting element, thereby improving the accuracy of driving and sensing.

[0135] The camera module may further include a second driving element, which includes a second driving coil. The second driving coil is correspondingly disposed with the attraction element, driving the second carrier to rotate about the second axis. The attraction element may further serve as a driving magnet to reduce the use of magnets, thereby reducing magnetic field interference and improving the accuracy of driving and sensing.

[0136] The attracting element can be a multi-pole magnet, comprising a fourth pole, a fifth pole, and a sixth pole. The fourth and fifth poles are arranged adjacent to each other and face the second drive coil. The sixth pole is arranged correspondingly to the first drive magnet, and is further away from the second drive coil than the fourth and fifth poles. This reduces interference between the two drive directions.

[0137] The first driving magnet includes a first magnetic pole and a second magnetic pole. The first and second magnetic poles are arranged adjacent to each other and face the first driving coil. The direction from the first magnetic pole to the second magnetic pole is defined as a first magnetization direction. The attracting element is a magnet with a second magnetization direction, causing the attracting element to attract the first driving magnet. The first magnetization direction is parallel to the second magnetization direction. This reduces interference between magnetic fields.

[0138] The number of first rolling elements is at least four, and the distance between the at least four first rolling elements and the first shaft is equal. This improves the stability of the first carrier rotating on the first shaft.

[0139] The base may further include a base magnet, through which the first axis passes. The first carrier may include a first magnetically conductive element, which is embedded in and extends from the first carrier. The base magnet attracts the first magnetically conductive element, causing the first carrier and the base to simultaneously contact the first rolling element assembly. This improves the assembly process of the camera module. Specifically, the first magnetically conductive element may be an iron sheet, which can further attract the first driving magnet.

[0140] In a cross-section passing through one of the first rolling elements and parallel to the first axis, the first rolling element includes an upper contact point, a lower contact point, an inner contact point, and an outer contact point. The upper contact point contacts the first carrier. The lower contact point contacts the base. The inner contact point is closer to the first axis than the upper and lower contact points. The outer contact point is farther from the first axis than the upper and lower contact points. The inner and outer contact points do not simultaneously contact the first carrier or the base. This improves assembly accuracy and prevents the optical path deflection element from the rotation axis of the first carrier.

[0141] The lower contact point of each first rolling element can define a plane, wherein the plane is perpendicular to the first axis. This allows the first rolling elements to be positioned on the same plane, further improving assembly accuracy.

[0142] The camera module may also include an imaging lens, which may comprise at least two lens groups. The first axis passes through at least one of the lens groups. By pre-optimizing the light from the incident light path deflection element, optical quality can be improved and glare reduced.

[0143] The attraction element can be embedded in the second carrier through injection molding. This reduces assembly errors and further stabilizes the adsorption force.

[0144] The first, second, and third axes are perpendicular to each other. This enhances the functionality of the optical path deflection element in driving optical image stabilization (OIS).

[0145] The optical path deflector may include a reflective surface that connects the first axis and the third axis. The first axis and the second axis intersect at the reflective surface. This prevents the optical axis from shifting during driving, thereby improving image quality.

[0146] The second rolling element can be disposed between the attraction element and the first driving magnet, thereby preventing the second carrier from deforming due to force.

[0147] The second carrier may further include an assembly bump that protrudes from the second axis in a direction away from the optical path deflection element, and an attraction element is disposed on the assembly bump. The first carrier may include a receiving structure that receives the assembly bump, and a second set of rolling elements is disposed between the assembly bump and the receiving structure. This improves the assembly of the camera module.

[0148] The first driving element is symmetrically arranged on the opposite side of the optical path deflection element in the second axial direction. The attraction element is symmetrically arranged on the opposite side of the optical path deflection element in the second axial direction and corresponds to the first driving magnet of the first driving element. By symmetrically arranging the driving magnet and the attraction element, uneven magnetic force can be avoided, thereby further improving the carrier holding effect.

[0149] This disclosure provides a camera module comprising a lens group, an optical path deflection element, a base, a first rolling element group, a first carrier, a second rolling element group, a second carrier, and a first driving body. A first axis passes through a center of the lens group. The optical path deflection element is disposed on an image side of the lens group, deflecting light rays from the first axis to a third axis. The first rolling element group is disposed on the base and includes at least three first rolling elements, each equidistant from the first axis. The first carrier is connected to the base via the first rolling element group and rotates about the first axis. The second rolling element group is disposed on the first carrier and includes at least two second rolling elements. A second axis passes through the center of each second rolling element, is perpendicular to the first axis, and is also perpendicular to the third axis. The second carrier is connected to the first carrier via the second rolling element group and rotates relative to the first carrier about the second axis. The optical path deflection element is fixed to the second carrier. The first driving body includes a first driving magnet and a first driving coil. The first driving magnet is fixed to the first carrier. The first drive coil is fixed to the base, and the first drive body drives the first carrier to rotate about the first axis.
