Description

Lifting assembly, camera device and electronic equipment Technical Field The application relates to the technical field of camera shooting, in particular to a lifting assembly, a camera device and electronic equipment. Background With the continuous development of electronic equipment integration technology, photographing and shooting become one of the functions commonly used by electronic equipment, so that the application of cameras in the electronic equipment is more and more extensive. In order to meet different shooting requirements and appearance size requirements, a camera in the electronic equipment can have a lifting function. At present, in order to drive the camera to lift under different use environments or different use states, the power source can be designed according to the maximum set load so as to provide enough acting force for the camera, so that the output power of the power source is increased. Disclosure of Invention The application provides a lifting assembly, a camera device and electronic equipment, which are used for reducing the output power of a power source required in the process of driving a camera to lift under different use environments or different use states. In order to achieve the above purpose, the application adopts the following technical scheme: In one aspect of the application, a lift assembly is provided that includes a base, a lift bracket, a motor, and an elastic assembly. The lifting bracket and the base are stacked. The lifting support and the base enclose a containing cavity, and the containing cavity is used for containing at least part of the camera module. The motor is located and holds the chamber outside, and this motor sets up on the base, and the output shaft of motor extends along first direction. The elastic component is positioned outside the accommodating cavity. The elastic component is connected with an output shaft of the motor, and the elastic component is also connected with the lifting support in a sliding manner along the second direction. The motor is used for driving a part of the elastic component to slide along a second direction relative to the lifting support and elastically deform through rotation of the output shaft. Under the condition that the elastic deformation part of the elastic component is in a compressed state, the elastic component is used for driving the lifting support to lift or descend along a third direction relative to the base. In addition, any two directions among the first direction, the second direction, and the third direction are perpendicular. According to the above, the lifting support and the base enclose the accommodating cavity to accommodate at least part of the camera module, and the lifting support can ascend or descend along the third direction, so that the lifting support can synchronously lift along with the camera module, thereby achieving the purposes of reducing the thickness of the whole electronic equipment, changing the shooting visual angle and the like. Based on this, because the elastic component is connected with the output shaft of motor, the elastic component still follows second direction sliding connection with the lifting support, and consequently the moment that the output shaft rotation of motor produced can pass through the elastic component and transmit to the lifting support to drive lifting support and go up and down. Specifically, the output shaft of the motor may rotate about a first direction to drive a portion of the elastic assembly to slide in a second direction relative to the lifting bracket. During the sliding of the driving elastic assembly, a portion of the driving elastic assembly may be elastically deformed (e.g., compressed or stretched). In addition, when the elastic component is in a compressed state, the elastic component is used for driving the lifting support to lift or descend along a third direction relative to the base. Under the condition that the elastic component is in a compressed state, the elastic component drives the lifting support to lift, so that a force arm (namely a part which can generate elastic deformation in the elastic component) between the motor and the lifting support is reduced, the moment required by the lifting support in the lifting process is correspondingly reduced, and the reduction of the output power of the motor is facilitated. In this case, when the use environment (for example, under different hydraulic environments) or the use state (for example, different photographing angles) is changed to cause a load change, the deformation amount of the portion of the elastic member capable of being elastically deformed is also changed accordingly. In the deformation range of the elastic component elastic deformation part, the force arm between the motor and the lifting support can be reduced along with the increase of the load, and vice versa. In this way, even if the load is increased, the moment (product of the load and the moment arm)
