[0027] Such as figure 1 As shown, the embodiment of the present invention provides a method for fixing a motor movable device, which is applied to a mobile terminal including a camera module. The camera module includes a drive IC and a motor. The motor includes: a motor housing, for The carrying part carrying the lens and the motor base connected to the above-mentioned drive IC, the carrying part can move in the space formed by the above-mentioned motor base and the motor housing, and the above-mentioned carrying part is provided with a coil, and the fixing method includes:

[0028] Step 101: Detect whether the mobile terminal is in a falling state.

[0029] Here, by detecting whether the mobile terminal is in a dropped state, it is determined whether to provide a forward driving current or a reverse driving current to the coil on the bearing part.

[0030] Specifically, whether the mobile terminal is in a falling state can be detected through a gravity sensor inside the mobi...

Abstract

The invention provides a fixing method for a moveable motor device and a mobile terminal. The invention aims to solve the problem that a present smart phone camera cannot fix a carrier in a middle motor. The fixing method provided by the invention comprises the following steps of: detecting if the mobile terminal is under a falling state; supplying a forward driving current or a backward driving current to a coil on a bearing part through a driving IC if the mobile terminal is under the falling state; and supplying the backward driving current to the coil on the bearing part through the driving IC if the mobile terminal is not under the falling state and a camera module is under non-work state. The bearing part is fixedly arranged on a motor base under the effect of the backward driving current and is fixedly arranged on a motor shell under the effect of the forward driving current. According to the invention, the bearing part is fixedly arranged on the motor base or the motor shell according to the operation condition of the mobile terminal, so that the bumping between the base in the motor and the bearing part can be effectively prevented, the cleanness of the camera is effectively guaranteed and the shooting effect is promoted.

Description

technical field [0001] The invention relates to the technical field of electronic applications, in particular to a method for fixing a motor movable device and a mobile terminal. Background technique [0002] Miniature camera modules are mainly used in consumer electronics products, especially smartphone products. In order to meet consumers' demand for light, thin and convenient electronic products, the structural space of products is getting smaller and smaller. Therefore, the large structural "motor" in the micro camera module must reduce the occupied space; while reducing the occupied space of the motor structure, in order not to Affecting the focusing effect of auto-focus AF, the center-mounted motor that arranges the lens and motor for focusing in the middle of the entire camera came into being. [0003] However, the introduction of the mid-mounted motor has brought new risks: the internal movable device (the carrying part carrying the lens) of the mid-mounted motor is...
