Problems solved by technology

When the user uses the camera of the mobile device to take pictures, it is easy to shake, resulting in blurred images
For this reason, an optical anti-shake motor is added to the camera of the mobile device, and an optical anti-shake drive device is used to perform shake compensation when the camera is shooting, so that the captured image is clear. Complicated, future high-end cameras have little use value

Embodiment 1

[0039] see figure 1 and figure 2 , figure 1 is a structural schematic diagram of the drive module of the present invention, figure 2 is an exploded view of the drive module of the present invention. An embodiment of the present invention provides a driving module 10, the driving module 10 can be equipped with various focus motors, so that the focus motor has optical anti-shake performance, and at the same time, after the focus motor is equipped, the optical axis accuracy of the AA process of the module can be improved . Specifically, the drive module 10 includes a stator component 101 and a mover assembly 102 .

[0040] In an embodiment of the present invention, the stator component 101 includes a casing 1011 and a driving circuit 1012. In this embodiment, the shape of the casing 1011 may be a square, or other shapes such as a circle or a hexagon. In order to facilitate the mounting of the focus motor, a mounting slot is generally provided in the middle of the housing 1...

Embodiment 2

[0065] see Figure 7 , Figure 7 It is a structural schematic diagram of the camera module of the present invention. An embodiment of the present invention provides a camera module, which includes the above driving module 10 . Specifically, the camera module 20 includes a focus motor 30 and a lens assembly 40. The lens assembly 40 includes an image sensor. The focus motor 30 is connected to the lens assembly 40. When specifically connected, the lens assembly 40 is connected to the focus motor 30 On the carrier, the image sensor is connected to the X-direction bracket 10211 of the driving module 10. When the coil of the focus motor 30 is energized, the carrier can move along the optical axis direction of the lens assembly 40, so that the lens assembly 40 can be driven to realize automatic focusing; At the same time, the driving module 10 can perform shake compensation on the image sensor.

Embodiment 3

[0067] see Figure 8 , Figure 8 It is a structural schematic diagram of the electronic equipment of the present invention. An embodiment of the present invention provides an electronic device, which includes the aforementioned camera module 20 . Specifically, the electronic device 50 can be a mobile phone, a tablet computer, a phone watch, a security camera, a vehicle camera, etc., and the electronic device includes a camera module 20 and a casing 501 , and the camera module 20 is arranged on the casing 501 .

[0068] The above-mentioned drive module, camera module and electronic equipment are equipped with various focus motors on the drive module, and use the interaction between the stator component and the mover component to make the focus motor have optical anti-shake performance. Moreover, the present invention uses the X-direction shrapnel and the Y-direction shrapnel to replace the previous suspension wires, which increases the travel space and makes the optical anti-...

Abstract

The invention discloses a driving module, a camera module and electronic equipment, the driving module comprises a stator component, the stator component comprises a shell and a driving circuit, and the driving circuit is fixed in the shell; a rotor assembly which comprises an X-direction moving unit, an X-direction elastic piece, a Y-direction moving unit and a Y-direction elastic piece, the X-direction elastic piece is connected with the X-direction moving unit and the Y-direction moving unit, the Y-direction elastic piece is connected with the shell and the Y-direction moving unit, and the X-direction moving unit and the Y-direction moving unit are connected with the driving circuit; when the driving circuit drives the X-direction moving unit and the Y-direction moving unit to move at the same time, the Y-direction moving unit can drive the X-direction moving unit to move in the Y direction, so that the X-direction moving unit does compound motion in a plane formed by the X direction and the Y direction. The invention has the advantages of good optical anti-vibration performance, simple process, low cost and the like.

Description

technical field [0001] The invention relates to the technical field of micro motors, in particular to a driving module, a camera module and electronic equipment. Background technique [0002] With the development of mobile terminal technology and shooting technology, more and more users use cameras on mobile terminals to shoot scenes they see. When a user uses a camera of a mobile device to take pictures, it is easy to shake, resulting in blurred images. For this reason, an optical anti-shake motor is added to the camera of the mobile device, and an optical anti-shake drive device is used to perform shake compensation when the camera is shooting, so that the captured image is clear. More complex, future high-end cameras have little use value. Contents of the invention [0003] Based on this, it is necessary to provide a driving module, a camera module and an electronic device for the above technical problems, which can increase the optical anti-shake stroke, improve the ...
