Problems solved by technology

[0004] In order to enable the motor to drive the lens to achieve position control in different directions, the 8-wire SMA motor with 8 SMA wires has become the focus of development. However, the number of SMA wires in the 8-wire SMA motor is large. Sexual connection, the structure is more complex and difficult to achieve

Embodiment Construction

[0094] Before describing the embodiments of the present application, for the convenience of understanding, first explain the terms involved in the embodiments of the present application:

[0095] Shape memory alloy wire: An actuation wire formed of a material that has a shape memory effect through thermoelasticity and martensitic transformation and its inversion. The SMA actuation wire can undergo a phase change when the temperature changes, whereby the stress state also changes. At low temperature, the SMA actuating wire is in the martensite phase state; when the temperature rises, the SMA actuating wire transforms from the martensite phase to the austenite phase, and deforms and shrinks. Therefore, an electric current can be passed through the SMA actuating wire, and the heating effect of the current can be used to heat up the SMA actuating wire, so as to realize shrinkage deformation of the SMA actuating wire. When no current is passed through the SMA actuating wire, the S...

Abstract

The invention provides a motor, a camera module and terminal equipment. The motor comprises a base, a carrier and an actuating line assembly, the actuating line assembly comprises a connecting assembly and at least one pair of SMA actuating lines forming an angle with each other, and the SMA actuating lines are connected between the base and the carrier through the connecting assembly and drive the carrier to move relative to the base through stretching and retracting of the SMA actuating lines. The connecting assembly comprises conductive clamping jaws connected to the two ends of the SMA actuating line and a conduction connecting piece with an insulating layer arranged outside, and the conductive clamping jaws are in conduction connection with the outer connecting end of the motor through the conduction connecting piece. The electric connection reliability of the motor is high.

Description

technical field [0001] The present application relates to the field of mobile terminals, in particular to a motor, a camera module and a terminal device. Background technique [0002] With the development of science and technology, mobile terminals such as mobile phones are more and more widely used, and photographing and video recording have become one of the indispensable functions of the mobile terminal. [0003] Currently, mobile terminals such as mobile phones generally implement camera and video functions through a built-in camera module. In order to meet the needs of auto focus and anti-shake of the camera module, the camera module includes a motor, and the motor moves in different directions to drive the lens of the camera module and the image sensor to move relative to each other, so that the camera can adjust to different positions. objects are clearly imaged. Among them, the SMA motor made of shape memory alloy (shape memory alloy, SMA) wire has been widely used...
