Problems solved by technology

The structure of the initial connection between the carrier and the base makes the carrier need to continuously consume electric energy before moving relative to the base, and at the same time generate excess heat, and the carrier that abuts on the base can only move in one direction relative to the base in the initial state. Unable to perform two-way movement, and the movement of the carrier is short, which cannot meet the various needs of the camera

Abstract

The invention provides a camera drive motor low in power consumption. Multiple elastic parts, which are disposed at two ends of a carrier, of the camera drive motor jointly acts on the carrier to allow the initial state stress of the carrier to be balanced. The carrier is suspended relative to a base by the elastic part disposed at the lower end of the carrier. When the drive motor starts to work, certain displacement, relative to the base, of the initial state of the carrier exists, the carrier starts to move under magnetic field force, idle work of the drive motor in the initial state is avoided, heat power consumption is reduced greatly, the carrier can move bidirectionally in the initial state, the moving journey of the drive motor is increased, and various shooting requirements are satisfied.

Description

technical field [0001] The invention relates to a mobile phone camera, in particular to a camera driving motor with low power consumption. Background technique [0002] After the coil of the mobile phone camera drive motor is energized, due to the action of the magnetic field, the coil is forced to drive the carrier to move, and the carrier moves the lens to achieve zooming. The initial position of the existing carrier before power-on is to abut against the base of the motor, such as Figure 4 As shown, the displacement is S0=0. When the coil is energized, the electromagnetic force first overcomes the gravity and the preset elastic force to do work. Since the current in the initial stage is small, the electromagnetic force is smaller than the gravity and the preset elastic force, and the carrier is in a static state at this time, and then The current increases gradually. When the electromagnetic force is equal to the resultant force of gravity and the preset elastic force, t...
