Embodiment 1

[0023] Embodiment 1: as Figure 1 to Figure 3 As shown, a ball-based four-axis Tilt OIS anti-shake structure proposed by the present invention includes a housing 1, a lens holding device 2 arranged in the inner cavity of the housing 1 (which is the prior art, and will not be described in detail here), and the housing Body and lens holding device 2 are all square. A number of magnets 3 are evenly distributed on the inner wall of the housing 1, and a number of coils 4 corresponding to the magnets 3 are evenly distributed on the side wall of the lens holding device 2. 2. The winding directions of the coils 4 on opposite side walls are set in opposite directions, and a movable mechanism for facilitating the movement of the lens holding device 2 is arranged between the housing 1 and the lens holding device 2 .

[0024] Wherein the movable mechanism includes a first bracket 5 arranged on the inner wall of the housing 1, a second bracket 6 arranged on the side wall of the lens holdi...

Embodiment 2

[0028] Embodiment 2: A lens holding device 2 movable mechanism in an OIS motor, such as image 3 As shown, it includes a first bracket 5 arranged on the inner wall of the housing 1, a second bracket 6 arranged on the side wall of the lens holding device 2, an intermediate bracket 7 arranged between the first bracket 5 and the second bracket 6, and at least two The first ball 8 arranged between the first bracket 5 and the middle bracket 7 to facilitate translation or flipping of the middle bracket 7, at least two second balls 9 arranged between the second bracket 6 and the middle bracket 7, the first ball 8 The arrangement direction is perpendicular to the arrangement direction of the second balls 9 .

[0029] Through the first bracket 5, the second bracket 6, the middle bracket 7, the first ball 8, and the second ball 9, the multi-angle rotation of the lens clamping device 2 is realized, and the displacement change of the lens clamping device 2 is realized at the same time, an...

Embodiment 3

[0030] Embodiment 3: An OIS motor using the ball-based four-axis Tilt OIS anti-shake structure of Embodiment 1. The OIS motor realizes Tilt anti-shake and Shift anti-shake on the X-axis and Y-axis.

Abstract

The invention discloses an OIS motor and a four-axis Tilt OIS anti-shake structure based on balls. The four-axis Tilt OIS anti-shake structure based on balls comprises a shell and a lens clamping device arranged in an inner cavity of the shell. Several magnets are uniformly distributed on an inner wall of the shell. Several coils corresponding to the magnets are uniformly distributed on a side wall of the lens clamping device. Winding directions of coils located on a same side wall of the lens clamping device are consistent, the winding directions of the coils located on the two opposite sidewalls of the lens clamping device are opposite, and a movable mechanism facilitating movement of the lens clamping device is arranged between the shell and the lens clamping device. In the invention,Shitf anti-shake and Tilt anti-shake on an X axis and a Y axis can be realized at the same time.

Description

technical field [0001] The invention relates to the field of voice coil motors, in particular to an OIS motor and a ball-based four-axis Tilt OIS anti-shake structure. Background technique [0002] With the increasing popularity of smart phones, people have higher and higher technical requirements for taking photos with smart phones, expecting that the camera effect of mobile phones can reach the level of digital cameras. The digital camera can achieve the functions of optical image stabilization (OIS) and tilt-shift photography because it has a relatively complex mechanical structure to control the multi-dimensional movement of the lens. [0003] In order to improve the camera's camera capability on the basis of the hardware and software of the mobile phone itself, it is also a topic that smartphone manufacturers have been working on. Currently, TDK, Mistumid and other manufacturers in the market have been able to produce motors with OIS functions. The existing motors with...
