Problems solved by technology

[0004] In the prior art, the Hall elements are arranged on the same side of the printed coil, which leads to the design of the printed coils in different shapes to avoid the Hall elements, which makes the shapes of the printed coils on different sides different, and the control of the current is relatively complicated. , and the bottom plate needs to be installed with anti-fooling settings according to the printed coil, which further increases the production cost

Embodiment 1

[0036] In the present invention, the X direction, the Y direction and the Z direction constitute a virtual coordinate system, the Z direction is the axis direction of the base 100, the X direction and the Y direction are perpendicular to each other and constitute a horizontal plane, and the horizontal plane is parallel to the base 100 The axial direction is vertical, wherein, the X direction is the transverse direction of the horizontal plane, and the Y direction is the longitudinal direction of the horizontal plane.

[0037] see Figure 1 to Figure 5 , shows the driving assembly in the first embodiment of the present invention. In the three-dimensional XYZ rectangular coordinate system, the driving assembly includes a base 100, a carrier 200 on the base 100, and a cover on the carrier 200 and The cover plate 300 on the base 100 is provided with an upper elastic piece 220 and a suspension wire 222 connecting the upper elastic piece 220 and the base 100 on the carrier 200. The ...

Embodiment 2

[0055] The present invention also proposes a camera module, the camera module includes a lens, an imaging sensor, and the above-mentioned drive assembly;

[0056] Wherein, the lens is arranged on the carrier and can move axially under the drive of the carrier, the imaging sensor is arranged on the side of the base away from the lens, and the imaging sensor and the The lenses are arranged relatively on the path of the optical axis.

Embodiment 3

[0058] The present invention also proposes an electronic device, including the above-mentioned camera module.

[0059] To sum up, the drive assembly, camera module and electronic equipment in the above-mentioned embodiments of the present invention divide the base into a circuit layer and a bottom plate, conduct electricity through the circuit layer, and drive the magnet to move along the X direction and / or Y direction, driving the magnet where it is located. The floating device moves along the X direction and / or Y direction, so that the Hall element senses the offset in the X direction and / or Y direction, so as to realize the position compensation of the shake and enhance the anti-shake performance. At the same time, by The connecting wires are embedded in the base, which can simplify the wiring of the connecting wires and reduce the assembly process and manufacturing process; specifically, the first groove and the second groove are arranged on the lower surface of the base, s...

Abstract

The invention provides a driving assembly, a camera module and electronic equipment. The driving assembly comprises a base, a carrier and a cover plate, the carrier is provided with an upper elastic sheet and a suspension line, the base comprises a bottom plate and a circuit layer, two sides of the bottom plate are connected with a plurality of PINs, the PINs are connected with the circuit layer through connecting lines, the connecting lines are embedded in the bottom plate, the lower surface of the bottom plate is at least provided with a first groove and a second groove, the first groove is internally provided with a first Hall element, and the second groove is internally provided with a second Hall element. And a second Hall element is arranged in the second groove. The base is divided into the circuit layer and the bottom plate, and the first groove and the second groove are formed in the lower surface of the base, so that the Hall element can be accommodated in the grooves, and the problems that the printed coils on different sides are different in shape and relatively complex in current control due to the fact that the printed coils need to avoid the Hall element and are designed into different shapes are solved. In addition, the bottom plate does not need to be provided with fool-proof arrangement according to printed coils, and production cost is further saved.

Description

technical field [0001] The invention relates to the technical field of voice coil motors, in particular to a driving assembly, a camera module and electronic equipment. Background technique [0002] With the rapid development of the camera industry, products equipped with cameras are becoming more and more popular, including mobile phone cameras, IPAD cameras, etc., and have become indispensable equipment in people's lives. [0003] In the process of shooting with a product equipped with a camera, the automatic focus function of the shooting is usually completed by a voice coil driver component (VCM), through which the position of the lens can be adjusted to present a clear image. The voice coil motor has the characteristics of high frequency response and high precision. The main principle is that in a permanent magnetic field, by changing the DC current of the inner coil of the motor, the carrier and the lens fixed on the carrier are driven to move axially, so as to realiz...
