Problems solved by technology

[0004] The stator and the rotor require a long matching stroke, resulting in a longer length of the stator yoke and the rotor yoke in the optical axis axis, and the longer length leads to an increase in cost, and also leads to an increase in the volume of the final motor, and the design is unreasonable

Embodiment 1

[0048] like Figure 4 and Figure 9 - Figure 10 As shown, the lens driving device includes a continuous zoom driving yoke group, in particular, the continuous zoom driving yoke set of the present embodiment is located in a chamber formed by the base 1 and the outer casing 5, the yoke group including a tube 2, a rotor magnetic Yoke 70 and the stator yoke 80.

[0049] The drum 2 is built into the chamber and the axial direction is rotatably connected to the outer casing 5, and the rotor 2 is fixed axially opposite the outer casing 5, and the axial direction of the drum 2 is extended to the base 1 side and is free;

[0050] The rotor is fixed to the base and can be rotated, in which the length of the rotor is largely shortened, and the rotor yoke and the stator yoke are greatly shortened in the axial direction of the optical axis, which can be reduced. The optical axis length of the small lens driving device can be applied to a thinner or ultra-thin imaging terminal.

[0051] The rotor...

Embodiment 2

[0108] like image 3 As shown, the lens driving device has a continuous zoom driving yoke group according to the first embodiment.

Embodiment 3

[0110] like Figure 7 As shown, the imaging device has a lens driving device according to the second embodiment, and a lens is mounted on the lens driving device.

Abstract

The invention relates to a continuous zooming driving magnet yoke group. The technical problem of high cost in the prior art is solved. The continuous zooming driving magnet yoke group comprises a rotary drum, a rotor magnet yoke and stator magnet yokes; the rotary drum is arranged in the cavity, one axial end of the rotary drum is rotatably connected with the shell, and the other axial end of the rotary drum extends towards the side of a base and is in a free shape; the rotor magnet yoke is cylindrical and sleeves the outer wall of the rotary drum; the rotor magnet yoke and the rotary drum are fixedly connected in the circumferential direction; the plurality of stator magnet yokes are fixed on the base, and each stator magnet yoke is provided with a coil groove; and the stator magnet yokes are distributed on the periphery of the rotor magnet yoke with the axis of the rotor magnet yoke as the center. The continuous zooming driving magnet yoke group has the advantage that the cost is greatly reduced.

Description

Technical field [0001] The present invention belongs to the field of imaging motors, and more particularly to a continuous zoom driving yoke group, assembly method, lens driving device, and imaging device. Background technique [0002] The micro-camera long focal lens has been widely used on high-end mobile phones, and the image sensor pixels applied are also raised from 8 megapixels to more than 100 million pixels, so the equivalent focal length of the microscopic lens is far exceeding the thickness of the mobile phone body. Although the dosal motor is a mature solution for mobile phone, the pixel is greatly improved, and the outer diameter of the lens is increasingly large, and the application of the baked motor is limited. Therefore, the microbiroscope telescopic camera can not only solve the oversized pixel telephoto lens on the phone, but also greatly enhance the image quality. [0003] With the inventors, the mating drive carrier frame with the stator and the rotor is axial...
