Description

Technical Field

[0001] The utility model relates to the technical field of cameras, in particular to a camera module. Background Art

[0002] With the development of optical imaging technology, camera modules are widely used in various imaging devices such as digital cameras and camcorders. With the continuous development of digital camera technology, the body of the camera is often small and light, which is easy to cause the light to shift corresponding to the imaging position on the camera module due to vibration during the imaging process, thus causing the captured image to be blurred. The current anti-shake methods are mainly divided into electronic and optical methods, among which optical anti-shake has a better effect. Optical anti-shake can traditionally be divided into two types: one is lens anti-shake, that is, according to the direction and degree of camera vibration, the position and angle of the lens are adjusted accordingly to make compensation so that the optical path remains stable; the other is imaging device anti-shake, that is, after sensing the camera vibration, the image sensor actively moves in the opposite direction to keep the image stable. Whether it is lens anti-shake or imaging device anti-shake, a brake needs to be set in the camera module to drive the lens or image sensor to move to compensate for the vibration.

[0003] The existing brakes for camera modules are mostly used for autofocus, that is, to drive the lens module or image sensor to move along the optical axis of the camera module. However, for traditional camera modules, manual or XYZ direction driving is adopted. However, if threaded rods and sliding rods are used at both ends of the longitudinal direction during the movement, unbalanced movement may occur. For example, Figure 5 The YAZ shaft structure in the prior art has a relatively poor stabilizing effect compared to the lack of a transmission shaft. Utility Model Content

[0004] The purpose of the utility model is to provide a camera module, which drives the belt to rotate through the drive of the X-axis motor, thereby rotating the transmission shaft, and then drives the threaded rod at the end to rotate through the transmission shaft. After the rotation, the threaded rod can be rotated, and after the rotation, the Y-axis can be rotated, so as to facilitate the completion of longitudinal position movement, improve the rotation drive effect at both ends, and have better stability.

[0005] To achieve the above-mentioned purpose, a camera module is provided, comprising: a first X-axis, a second X-axis and a Y-axis, the other side of the first X-axis is matched with the second X-axis, and the second X-axis has the same structure as the first X-axis, one end of the first X-axis and the second X-axis are slidably matched with an XY-axis connecting plate, the top end of the XY-axis connecting plate is fixedly connected with the Y-axis, the front side of the Y-axis is slidably matched with a sliding plate, the front side of the sliding plate is fixedly connected with a Z-axis, and the other ends of the first X-axis and the second X-axis are rotatably matched with a transmission shaft.

[0006] According to the camera module, a Y-axis motor is fixedly connected to the top of one end of the Y-axis.

[0007] According to the camera module, the top end of the sliding plate is fixedly connected to a Z-axis motor.

[0008] According to the camera module, the outer portion of the Z-axis is slidably matched with a camera mounting plate.

[0009] According to the camera module, the bottom ends of the first X-axis and the second X-axis are fixedly connected to a plurality of support seats.

[0010] According to the camera module, one end of the first X-axis is fixedly connected to an X-axis motor, and the driving end of the X-axis motor is matched with a transmission shaft belt sleeve.

[0012] 1. The utility model is provided with an X-axis motor and a transmission shaft. The belt is driven by the X-axis motor to rotate, thereby rotating the transmission shaft. The threaded rod at the end is then driven by the transmission shaft to rotate. After the rotation, the threaded rod can be rotated, and the Y-axis can be rotated after the rotation, which is convenient for completing the longitudinal position movement, improving the rotation drive effect at both ends, and having better stability.

[0013] 2. The utility model is provided with an X-axis, a Y-axis and a Z-axis. The X-axis, Y-axis and Z-axis structures are used in conjunction with the camera module to ensure shooting stability, achieve an anti-shake effect and improve use efficiency.
