CAMERA DEVICE AND ELECTRODE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/127921
Kind Code:
A1
Abstract:
A camera device and an electronic apparatus. The electronic apparatus comprises the camera device. The camera device comprises a lens module, a screw rod, a push block, a driving mechanism connected to the screw rod, a transmission assembly, and a detection assembly; the push block is sleeved on the screw rod, can move along the axial direction of the screw rod, and is in threaded fit with the screw rod; the transmission assembly is connected to the push block and the lens module so as to drive the lens module to make linear movement; the detection assembly is configured to detect the position of the lens module, and comprises a magnetic circuit system and a Hall element arranged at a fixed position; the magnetic circuit system comprises magnetic steel and a magnetic conductive plate having a magnetic conductive body and several protrusions protruding from the magnetic conductive plate body; the magnetic steel rotates along with the lead screw; when the magnetic conductive body is sleeved on the magnetic steel and rotates along with the magnetic steel and the screw rod drives the protrusions to rotate, the intensity of the magnetic field at the Hall element changes along with the rotation angle; the position state of the lens module can be determined by means of the change in the intensity of the magnetic field; real-time position feedback is carried out when the lens module encounters an obstacle or an external force changes the state of the lens module.
