when the light signal detecting unit detects that the effective light signal is switched to the state of intermittent type, the control module controls the motor 30 to continue rotating; when the light signal detecting unit detects that the effective light signal is in a state of being maintained or absent, the control module controls the motor 30 to stop rotating.
Usually, the housing 10 is further provided with at least one trigger switch for triggering when the mobile phone is taken or placed, and the trigger switch is connected to the control module. The trigger switch can be a contact trigger switch or a non-contact trigger switch, wherein the contact trigger switch can be a touch switch, a button, a gravity switch and the like, and the non-contact trigger switch can be NFC, Wi-Fi, an infrared sensor, a pressure sensor, voice, gestures and the like; when the mobile phone is put in and the trigger switch is triggered, the motor rotates in the forward direction, the clamping arm 21 is folded, and in the process of folding the clamping arm 21, the optical signal detection unit side detects that the effective optical signal is in an intermittent switching state or a non-intermittent switching state (namely, the optical signal is received, the optical signal is not received, and the optical signal is received). When the clamping arm 21 clamps the mobile phone, the clamping arm 21 does not move within a certain time, and the optical signal detection unit side detects that an effective optical signal is in a state of being maintained or absent within a certain time, the control module controls the motor 30 to stop rotating; the clamp arms 21 maintain a clamped state to the handset.
Next, the working process of the light-sensing controlled electric clamping bracket will be briefly described with reference to fig. 1 and 7:
