Embodiment 1

[0033] Embodiment 1: as Figure 1 to Figure 6 As shown, a multi-stage telescopic structure proposed by the present invention includes a base 1, a telescopic mechanism disposed between the base 1 and the lens driving assembly, and an anti-shake mechanism for anti-shaking the image sensor.

[0034] The telescopic mechanism includes a first telescopic assembly and a second telescopic assembly, and the first telescopic assembly and the second telescopic assembly have different structures. The first telescopic assembly includes a first support body 2 and a first driving structure arranged on the base 1 and driving the first support body 2 to move perpendicularly to the base 1 . The first driving structure includes two symmetrically arranged driving rods 3 with one end connected to the first support body 2, a slider 4 connected to the other end of the driving rod 3, arranged on the base 1 and allowing the two sliders 4 to slide The sliding seat 5 that moves, the first driving eleme...

Embodiment 2

[0038] Embodiment 2 is different from Embodiment 1 in that several groups of the second telescopic assembly can be provided, that is, the second supports 7 of several groups of the second telescopic assembly are mutually socketed, and the lens carrier structure is installed on the innermost second Support 7.

Embodiment 3

[0039] Embodiment 3: a kind of lens driving device, such as Figure 7 with Figure 8 As shown, it has the multi-stage telescopic structure described in Embodiment 1 or Embodiment 2, and also includes a lens drive assembly arranged on the second support body 7. The lens drive assembly includes a frame body 19 connected to the second support body 7, several settings The magnet 20 on the frame body 19 , the carrier 21 arranged in the inner cavity of the frame body 19 for mounting the lens, and the coil 22 arranged on the carrier 21 and corresponding to the magnet 20 . And the end of the second supporting body 7 away from the base 1 is integrally formed with an inward-turning flange 23. The frame body 19 includes an upper sub-frame 24 and a lower sub-frame 25. The upper sub-frame 24 is fixed to the flange 23, and the flange 23 protrudes from the The inner side wall of the upper sub-frame 24 and the inner side wall of the lower sub-frame 25 are integrally formed with a protruding ...

Abstract

The invention discloses a multi-section telescopic structure, a lens driving device, a photographing device and an electronic product, and the key points of the technical scheme are that the multi-section telescopic structure comprises a base, a telescopic mechanism arranged between the base and a lens driving assembly, and an anti-shake mechanism used for preventing an image sensor from shaking; the telescopic mechanism comprises a first telescopic assembly and a second telescopic assembly. The first telescopic assembly comprises a first supporting body and a first driving structure which is arranged on the base and drives the first supporting body to move perpendicular to the base. The second telescopic assembly comprises a second supporting body connected with the first supporting body in a sleeved mode and a second driving element arranged between the first supporting body and the second supporting body and used for driving the second supporting body to stretch out and draw back. According to the invention, a multi-section continuous telescopic function is realized, and a large-stroke and long-focusing function is achieved; the translation anti-shake function of the image sensor is realized, the focal length of the lens is precisely adjusted, and the camera shooting precision is improved.

Description

technical field [0001] The invention relates to the field of photographic equipment, in particular to a multi-stage retractable structure, a lens driving device, a photographic device and electronic products. Background technique [0002] Camera modules with auto focusing (AF, Auto Focusing) functions are widely used in mobile electronic products such as digital cameras, mobile phones or tablet computers. [0003] With the development of high-precision and high-magnification cameras, for example, the optical image stabilization function that corrects hand-shake, vibration, etc. when using a smartphone to take pictures or video is using more complicated hand-shake, vibration, etc. correction methods . The existing lens driving device is limited by the volume size, it is difficult to move the lens in a large stroke, and the existing segmented lens driving device has a complex structure and a large volume, which is not conducive to the development trend of thinner and smaller ...
