The invention discloses a telescopic control device of a mobile phone lens, comprising a controller, a sensor, a reflector and a lens driving device, wherein, the controller is used for providing working power supply and sending out control signals; the sensor is electrically connected with the controller, is used for receiving induction signals reflected by the reflector and then feeds back the signals to the controller; the reflector is arranged on the lens; and the lens driving device is connected with the sensor and is used for driving the telescope of the driving lens. By adopting the control of an accurate four-phase stepping motor and an infrared receiving sensor, the telescopic control device accurately realizes the driving of mobile phone telescopic lens camera motor, and has thecharacteristic of high-accuracy controllable stepping.
Description
technical field [0001] The invention relates to a telescopic control device for a mobile phone lens, in particular to a stepping motor control device for a mobile phone with a telescopic lens. Background technique [0002] At present, camera technology has been widely used in mobile phones, but due to many factors such as the camera module (sensor) on the mobile phone, the integration level of the control chip, the size of the chip package, the size of the mobile phone, and the cost of the high-pixel sensor, etc. The camera lens of the mobile phone cannot be retracted, thus becoming a bottleneck for improving the imaging effect of the mobile phone camera. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a stepping motor control device for a mobile phone with a telescopic lens with high-precision stepping control, in order to overcome the defect that the lens of the existing mobile phone camera technology cannot be...
