Problems solved by technology

[0002] Recently, the rapid development of miniaturization technology has enabled the application of optical drive devices on miniature cameras. Generally, the movement angle of optical drive devices is about 5 degrees, which mainly plays the role of anti-shake for static cameras, and cannot take into account the tracking function of dynamic cameras.

Embodiment 1

[0050] In this embodiment, the X-axis and the Y-axis are located on a horizontal plane, and they are vertically connected, while the Z-axis is perpendicular to the intersection of the X-axis and the Y-axis, and the Z-axis can be understood as an optical axis.

[0051] Such as figure 1 and figure 2 As shown, an optical drive device of the present invention includes a top cover 1, a fixed outer frame 6 and a bottom cover 7, and the fixed outer frame 6 is provided with an inner ball bracket A and an anti-shake middle frame 5 sequentially from inside to outside.

[0052] Such as image 3 and Figure 4 As shown, the anti-shake middle frame 5 includes a first ear cover 51 and a second ear cover 52 , and the first ear cover 51 and the second ear cover 52 are respectively distributed on both sides of the X axis. The first ear cover plate 51 and the second ear cover plate 52 are connected together to form an integrated structure, and the outer wall of the first ear cover plate 51 i...

Embodiment 2

[0068] Such as Figure 10 As shown, this embodiment provides a lens driving device, which has the optical driving device described in Embodiment 1, and

[0069] The lens carrier is fixed in the inner ball bracket A of the optical driving device. The lens carrier can be an AF motor or a single carrier.

[0070] Further, the lens driving device further includes a sensor assembly fixed on the lower end of the lens carrier, and the sensor assembly is connected to the bent flexible power supply board. The sensor component may be a Hall sensor, which is used to detect the position of the lens carrier after movement, ie, the position on the optical axis.

Embodiment 3

[0072] Based on Example 2, such as Figure 11 As shown, this embodiment provides an imaging device, which has the lens driving device described in the second embodiment. For example, mods with lenses, etc.

Abstract

The invention relates to an optical driving device, an imaging device and electronic equipment. The optical drive device includes a fixed outer frame and an anti-shake middle frame, which is located in the fixed outer frame; the anti-shake middle frame and the fixed outer frame are rotatably connected and the anti-shake middle frame rotates around the X axis; the outer wall of the anti-shake middle frame has an anti-shake When the middle frame rotates around the X axis, the avoidance structure prevents the anti-shake middle frame from contacting the inner wall of the fixed outer frame; the inner ball bracket is located in the anti-shake middle frame; the shape of the inner ball bracket is spherical, and the inner ball bracket is used to carry optical components The inner ball bracket and the anti-shake middle frame are rotatably connected and the inner ball bracket rotates around the Y axis; the anti-shake middle frame driving mechanism drives the anti-shake middle frame to rotate around the X axis; the inner ball bracket driving mechanism drives the inner ball The bracket rotates around the Y axis. The present invention is an optical drive device for large-angle motion. With the viewing angle of the lens, the viewing angle of the present invention can cover 175 degrees, and can simultaneously realize the optical anti-shake of static photography and the tracking function of dynamic photography.

Description

technical field [0001] The invention belongs to the technical field of motors, and in particular relates to an optical driving device, an imaging device and electronic equipment. Background technique [0002] Recently, the rapid development of miniaturization technology has enabled the application of optical drive devices in miniature cameras. Generally, the movement angle of optical drive devices is about 5 degrees, which mainly plays the role of anti-shake in static cameras, and cannot take into account the tracking function of dynamic cameras. Nowadays, micro-cameras are more widely used in sports situations, and the technology of optical drive devices with larger movement angles is currently in demand in the market. Contents of the invention [0003] The purpose of the present invention is to address the above problems and provide an optical drive device, an imaging device and an electronic device that can solve the above technical problems. The optical driving device...
