Abstract: Provided is an anti-vibration device, including a housing, a base fixed to the housing, and an anti-vibration mechanism accommodated in the housing. The anti-vibration mechanism includes a lens, a rolling member, a movable frame, an image sensor, and an electric actuator. The electric actuator includes a coil and a magnet, and the magnet and the coil are arranged opposite to each other to actuate the movable frame to drive the image sensor to move along the first direction and the second direction orthogonal to the optical axis. The anti-vibration mechanism adopts two coils arranged at intervals along the first direction two coils arranged at intervals along the second direction, so that the electric actuator drives the image sensor to rotate in the plane of the first direction and the second direction, which helps to improve the shooting effect.

Abstract: Provided is a lens drive including: a housing; a focus adjustment mechanism including a lens assembly having an optical axis and a fixing member fixed to the housing, the lens assembly is movably connected to the fixing member, and the lens assembly includes at least one lens piece movable along an optical axis; an anti-shake mechanism including a bottom plate fixed on the housing and an image sensor module movable relative to the bottom plate in a direction perpendicular to the optical axis; and a shock absorbing gel provided between the fixing member and the image sensor module. The shock absorbing gel can absorb the interaction force between the anti-shake mechanism and the focus adjustment mechanism when the lens drive is impacted by the external environment, thereby reducing the possibility of damage to the components in the lens drive.

Abstract: Provided is a camera device, including: a camera lens having an optical axis; a lens driving mechanism configured to drive the camera lens to move along the optical axis; an image stabilization mechanism including a movable frame, and an image sensor chip and a first flexible substrate arranged at the movable frame. The image stabilization mechanism is movable in a plane of the image sensor chip, and the first flexible substrate is made of liquid crystal polymer. The use of the LCP substrate for the first flexible substrate can greatly reduce elasticity of existing flexible substrates due to polyimide, so it has frequency characteristics similar to other rigid bodies and system resonance is not easily generated during movement of the image stabilization mechanism. Therefore, more precise servo control of the movable frame can achieved, thereby enabling camera device to have higher-quality hand-shake correction control and image stabilization control.
