Problems solved by technology

[0004] However, focusing with a long focal length requires an increase in the travel of the lens. However, the existing lens is driven by a single stroke, which takes a long time to focus and a relatively slow focus speed. When taking pictures, it is necessary to wait for the focus to be completed before proceeding, which seriously affects the photography. speed

Embodiment 1

[0035] Embodiment 1: as Figure 1 to Figure 5 As shown, the driving structures are set in two groups, and the two groups of driving structures are arranged in reverse, and each group of driving structures includes two coils 3 respectively installed on the side walls of the two sides of the carrier 2, and are arranged on the frame body 1. And the magnet group 4 corresponding to the carrier 2 . In this embodiment, the inner wall of the frame body 1 is provided with a mounting hole 5 for the installation of the magnet group 4, and the magnet group 4 is composed of two magnet groups 4 arranged along the optical axis direction, and the two magnet groups are closely arranged.

[0036] After the coil 3 is powered, it interacts with the magnet group 4 and drives the coil 3 and the carrier 2 to move along the optical axis to control the position of the corresponding lens and achieve the effect of focusing, and the corresponding lens is driven synchronously to move through the two sets ...

Embodiment 2

[0041] Embodiment 2, differs from Embodiment 1 in that: as Figure 6 As shown, in this embodiment, the driving structures are arranged in two groups, and the two groups of driving structures have the same direction, that is, the two carriers 2 are installed in the same direction. And the installation groove 17 in one group of driving structures of the crane is opened at the end of the frame body 1, and the step 18 is located at the middle position of the frame body 1; The groove 17 is located in the middle section of the frame body 1 .

Embodiment 3

[0042] Embodiment 3: as Figure 7 As shown, on the basis of Embodiment 1 or Embodiment 2, a casing 16 covering the frame body 1 and the driving structure is installed on the frame body 1. Both ends are equipped with a cover body 19, the cover body 19 is hollow and is convenient for light to pass through. The notch 21 where the folded edge 20 snaps into place. The shell 16 and the cover 19 play a protective role to ensure the normal operation of the present invention.

Abstract

The invention discloses a lens driving structure, a periscopic lens driving device, a photographing device and an electronic product. The lens driving structure comprises a frame body, wherein the frame body is provided with at least two groups of lens moving assemblies arranged along the optical axis direction; the lens moving assembly comprises a carrier, a driving structure which is arranged between the carrier and the frame body and drives the carrier to move along the optical axis direction, and a spring structure which is arranged between the carrier and the frame body and drives the carrier to reset. According to the lens driving structure, at least two lens moving assemblies are arranged, and the carrier is synchronously driven to move through the two lens moving assemblies, so the focusing speed is improved, and the rapid photographing effect is realized.

Description

technical field [0001] The invention relates to the field of photographic equipment, in particular to a lens driving structure, a periscope lens driving device, a photographing device and electronic products. Background technique [0002] In recent years, with the rapid development of various electronic products, people's demand for digital products is increasing, especially the quality of camera shooting is more stringent, hoping to record the details of life with high-quality images. [0003] The existing lens focusing method is to drive the lens to move through the lens driving device to achieve focusing; according to the requirements of the thickness of the mobile phone and the long focal length, a periscope lens driving device is provided. [0004] However, focusing with a long focal length requires an increase in the travel of the lens. However, the existing lens is driven by a single stroke, which takes a long time to focus and a relatively slow focus speed. When taki...
