Problems solved by technology

[0002] In the related art, when the motor is in use, most of the driven parts are driven by a transmission mechanism such as a slide rail device. As time increases, due to the aging of the transmission mechanism, the motor cannot realize the normal action of the driven part; for example, In order to achieve a full-screen design, some mobile terminal devices such as smart phones adopt a pop-up camera design, which drives the camera up through a motor, thereby avoiding opening holes in the screen, and then with the increase of use time, the transmission mechanism will age and the motor will run When the resistance increases, the motor cannot drive the camera to rise normally, making the electronic equipment unable to continue to use normally, which affects the user experience

Abstract

The application discloses a motor control device, electronic equipment and its control method. The motor control device includes a switching module and a motor driver. The switching module includes a control circuit and a switching switch. The control circuit has an output terminal, and the switching switch has multiple gears. bit, and the switching switch can switch the reference voltage of the output terminal, the motor driver is connected to the output terminal of the switching module, and the motor driver is adapted to be connected to the motor so as to load the output current of the motor driver to the motor. According to the motor control device of the present application, the driving force of the motor can be adjusted so as to match the driving force of the motor with the resistance encountered by the motor.

Description

technical field [0001] The present application relates to the technical field of electronic devices, in particular to a motor control device, electronic equipment and a control method thereof. Background technique [0002] In the related art, when the motor is in use, most of the driven parts are driven by a transmission mechanism such as a slide rail device. As time increases, due to the aging of the transmission mechanism, the motor cannot realize the normal action of the driven part; for example, In order to achieve a full-screen design, some mobile terminal devices such as smart phones adopt a pop-up camera design, which drives the camera up through a motor, thereby avoiding opening holes in the screen, and then with the increase of use time, the transmission mechanism will age and the motor will run When the resistance increases, the motor cannot drive the camera to rise normally, so that the electronic equipment cannot continue to be used normally, which affects the us...
