Description

Anti-shake drive device Technical Field

[0001] This invention relates to the field of drive technology, and more particularly to a shake-stabilizing drive device. Background Technology

[0002] As consumers demand a better shooting experience, image stabilization features of lens drive mechanisms are widely used in various video recording devices. The integration of lens drive mechanisms with various portable electronic devices such as mobile phones, camcorders, and computers is also gaining popularity among consumers. (Technical issues)

[0003] The image stabilization mechanism of a lens drive unit in related technologies typically consists of a coil and a magnet forming a drive structure. A support frame is mounted on a base, and a lens barrel bracket is located in the center hole of the base. The drive coil and drive magnet are fixed to the lens barrel bracket and support frame, respectively. The OIS coil (image stabilization coil) is fixed to the housing and located above the support frame, while the image stabilization magnet is fixed to the side of the support frame away from the base. When current is applied to the image stabilization coil, an electromagnetic field is generated between the coil and the magnet. The coil experiences a Lorentz force from this electromagnetic field, driving the magnet to move in a direction perpendicular to the optical axis, thereby stabilizing the lens barrel.

[0004] However, in the image stabilization devices of related technologies, the use of a single image stabilization coil and a driving magnet to generate a magnetic field to drive each other to achieve image stabilization results in a single image stabilization function and poor image stabilization effect. At the same time, if there is a deviation between the assembly position of the image stabilization coil and the driving magnet and the predetermined position, the image stabilization direction will deviate from the original preset path.

[0005] Therefore, it is necessary to provide a new anti-shake drive device to solve the above-mentioned technical problems. Technical solutions

[0006] The purpose of this invention is to provide a stabilization drive device that can achieve stabilization and stabilization correction.

[0007] To achieve the above objectives, the present invention provides an image stabilization driving device for driving an optical component to perform image stabilization movement. The optical component has an optical axis. The image stabilization driving device includes an image stabilization fixing part, an image stabilization movable part, a coil group, a magnet group, and a driver movably supported on the image stabilization fixing part. The optical component is fixed to the image stabilization movable part. One of the coil group and the magnet group is fixed to the image stabilization fixing part, and the other of the coil group and the magnet group is fixed to the image stabilization movable part. The magnet group and the coil group are spaced apart and opposite each other. The coil group and the magnet group interact to generate an electromagnetic force to drive the image stabilization movable part to move. The driver is mounted on the image stabilization fixing part and is used to control the driving direction of the coil group.

The third driver generates a third driving signal to drive the third coil group to interact with the third magnet group to generate a third driving force. The directions of the second driving force and the third driving force are at an angle to the direction of the first driving force. The second driving force and the third driving force work together to drive the anti-shake movable part to move along the second direction. Alternatively, the second driving force and the third driving force work together to drive the anti-shake movable part to rotate around the optical axis while moving along the second direction to achieve anti-shake in the second direction.

[0011] Preferably, when the second driving force and the third driving force are in the same direction or the second driving force and the third driving force are in opposite directions and unequal in magnitude, and the directions of the second driving force and the third driving force are both perpendicular to the direction of the first driving force, the second driving force and the third driving force work together to drive the anti-shake movable part to move along the second direction.

[0012] Preferably, when the second driving force and the third driving force are in the same direction or the second driving force and the third driving force are in opposite directions and unequal in magnitude, and the directions of the second driving force and the third driving force are both at acute angles to the direction of the first driving force, the second driving force and the third driving force work together to drive the anti-shake movable part to rotate around the optical axis to correct the direction of the anti-shake movement of the anti-shake driving device and make the anti-shake movable part move along the second direction.

[0020] Compared with the prior art, in the anti-shake driving device of the present invention, one of the coil group and the magnet group is fixed to the anti-shake fixing part, and the other of the coil group and the magnet group is fixed to the anti-shake movable part. The magnet group and the coil group are spaced apart and opposite each other. The interaction between the coil group and the magnet group generates an electromagnetic force to drive the coil group or the magnet group to move. The driver is installed on the anti-shake fixing part and is used to control the driving direction of the coil group. The second coil group and the third coil group are arranged spaced apart relative to each other along a first direction. The first direction and the second direction are perpendicular to each other and both are perpendicular to the optical axis. The first driver is used to generate a first driving signal to drive the first coil group and the first... The interaction of the magnets generates a driving force along a first direction, which drives the anti-shake movable part to move along the first direction, thus achieving anti-shake in the first direction.

The second magnet group 52 and the third magnet group 53 are opposite to each other, and both the second magnet group 52 and the third magnet group 53 are disposed on the side of the support frame 12 along the second direction. The first magnet group 51 is located on one side of the first coil group 41 and is spaced apart from each other, such that the first coil group 41 is within the magnetic field range of the first magnet group 51.

The resultant force of the fifth traction force F5 and the sixth traction force F6 is the first driving force. The magnitude and direction of the fifth traction force F5 and the sixth traction force F6 can be different.

The third driver is used to generate a third driving signal to drive the third coil group and the third magnet group to interact, thereby generating a third driving force. The directions of the second driving force and the third driving force are at an angle to the direction of the first driving force. The second driving force and the third driving force work together to drive the anti-shake movable part to move along the second direction to achieve anti-shake in the second direction. Alternatively, the second and third driving forces work together to drive the anti-shake movable part to rotate around the optical axis while moving along the second direction, correcting the movement of the anti-shake movable part that deviated from the original predetermined path back to the second direction. This novel rotary anti-shake device can achieve both anti-shake and anti-shake correction.

[0056] The above description is merely an embodiment of the present invention. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of the present invention, but these improvements all fall within the protection scope of the present invention.
