Problems solved by technology

as attached Figure 4 , the existing VCM motor adopts a straight-wound coil arrangement. Usually, 4 magnets are arranged on the 4 sides of the coil or 4 magnets are arranged at the 4 corners. greater spacing is required to avoid magnetic interference effects
Because of the magnetic flux leakage phenomenon of the motors, the distance between adjacent motors needs to be set larger to avoid excessive magnetic field interference between the motors, which will affect their motion characteristics and cause blurred images, but a large distance means that the motors need to occupy More internal space of the mobile phone runs counter to the design direction of the miniaturization and thinning of the mobile phone, and needs to be improved urgently

Abstract

The invention relates to a lens driving motor, a camera and a mobile terminal device.The lens driving motor comprises a shell, a base, an upper spring, a lower spring, a lens supporting body, a coil and a magnet module, the lens supporting body is elastically connected with the shell through the upper spring, and the lens supporting body is elastically connected with the base through the lower spring; the lens support body floats up and down along with the change of the current of the coil, the coil is vertically wound and arranged on the side wall of the lens support body, the magnet module is fixed in a magnetic conductive shell, and the magnetic conductive shell is made of a magnetic conductive material. According to the lens driving motor provided by the invention, the magnetic leakage phenomenon of a traditional motor can be effectively improved, so that the motor distance can be very small, the internal space of a mobile phone and other products is greatly saved, and the lens driving motor has very strong market competitiveness.

Description

technical field [0001] The present invention relates to the field of camera motors, in particular, to a lens driving motor, a camera and a mobile terminal device. Background technique [0002] With the development of mobile phones, multi-camera mobile phones have gradually become the mainstream. Most of the existing lens driving motors adopt the arrangement of straight-wound coils, and the phenomenon of magnetic flux leakage generally exists. as attached Figure 4 , The existing VCM motor adopts a straight-wound coil arrangement. Usually, 4 magnets are arranged on the 4 sides of the coil or 4 magnets are arranged at the 4 corners. The external magnetic flux leakage is basically the same around the entire motor. A larger distance is required to avoid the influence of magnetic interference. Due to the magnetic leakage phenomenon of the motor, the distance between adjacent motors needs to be set larger to avoid excessive magnetic field interference between the motors, which w...
