Problems solved by technology

[0004] Existing periscope camera modules generally include a stator, a mover, a first driving mechanism (to realize the AF driving function), and a second driving mechanism (to realize the OIS driving function). Since the first driving mechanism and the second driving mechanism both use The magnetic field works, and because the structure of the periscope camera module itself is small, when the mover moves relative to the stator, after the position of the coil and the magnet in the first drive mechanism and the second drive mechanism are shifted, magnetic interference is prone to occur

Embodiment 1

[0028] Embodiment 1: as Figure 1 to Figure 5 As shown, a driving structure proposed by the present invention includes a first driving mechanism 3 and a second driving mechanism 6 arranged between the stator and the mover, and the second driving mechanism 6 and the AF moving structure are respectively arranged on the upper and lower sides of the mover . In this embodiment, the first driving mechanism 3 and the second driving mechanism 6 are arranged in two groups and arranged symmetrically with respect to the centerline of the mover.

[0029] The first driving mechanism 3 and the second driving mechanism 6 are respectively arranged on both sides of the mover, the first driving mechanism 3 includes a first driving magnet 1 and a first driving coil 2, and the second driving mechanism 6 includes a second driving magnet 4. The second driving coil 5 . The N poles and S poles of the first driving magnet 1 are arranged along the moving direction of the mover; the N poles and S pole...

Embodiment 2

[0032] Embodiment 2: a kind of lens driving device, such as Figure 6 and Figure 7 It has the drive structure described in Embodiment 1, and a front spring set and a rear spring set are arranged between the stator and the mover. The front spring set and the rear spring set have the same structure. The positions of the sidewalls at both ends of the sub-moving direction. In addition, the front spring group or the rear spring group includes two spring groups 11 respectively located on the two side walls of the mover, that is, the spring groups 11 are respectively close to the two ends of the moving direction of the mover. The first drive coil 2 is electrically connected to the FPC board of the stator. The front spring group and the rear spring group have the same structure, so that the same structure can be used, which effectively saves costs and facilitates assembly.

Abstract

The invention discloses a driving structure, a lens driving device, a photographic device and electronic equipment, and is characterized in that the driving structure comprises a first driving mechanism and a second driving mechanism which are arranged between a stator and a rotor, and the first driving mechanism and the second driving mechanism are arranged on the two sides of the rotor respectively; the first driving mechanism comprises a first driving magnet and a first driving coil, the second driving mechanism comprises a second driving magnet and a second driving coil, and the first driving coil and the second driving magnet are connected to the rotor or the first driving magnet and the second driving coil are connected to the rotor. When the rotor moves, the magnetic interference condition is effectively reduced, the product performance is improved, and the thrust required for driving the rotor to move is reduced.

Description

technical field [0001] The invention relates to the field of photographic equipment, in particular to a driving structure, a lens driving device, a photographing device and electronic equipment. Background technique [0002] Shooting equipment generally includes a lens group, through which different lenses in the lens group refract different light rays to irradiate the image sensor to form an image. A motor is provided to drive the lens group to translate along the optical axis for focusing. [0003] In order to keep the mobile terminal thin and light, it is necessary to fold the optical axis of the camera module to shorten the size of the camera module in the thickness direction of the mobile terminal. This camera module with folded optical axis is a periscope camera module. [0004] Existing periscope camera modules generally include a stator, a mover, a first driving mechanism (to realize the AF driving function), and a second driving mechanism (to realize the OIS drivin...
