The clamping ends of the clamping assembly are close to each other so as to clamp the mobile device; wherein clamping of the mobile device by the clamp assembly can be by way of clamping of resilience of a spring, and can further be by way of the drive motor driving a left clamping frame and a right clamping frame to drive clamping;
After clamping the mobile device, step S310 is further included: a charging induction coil charges the mobile device.

The clamp assembly includes a left clamping frame and a right clamping frame, and its transmission mode with the drive motor adopts either transmission mode I or transmission mode II. Wherein, the transmission mode I is: an output shaft of the drive motor is provided with a gear. The left clamping frame and the right clamping frame are respectively abuttingly connected with a rack drivenly connected with a gear. The drive motor drives the left clamping frame and the right clamping frame to synchronously move towards or away from each other. At the same time, the left clamping frame and the right clamping frame respectively are respectively provided with a left elastic member and a right elastic member. When the motor is not working, the left clamping frame and the right clamping frame, under the action of elastic force, restore to the centre position to achieve the purpose of clamping. The transmission mode II is: an output shaft of the drive motor is provided with a worm. The left clamping frame and the right clamping frame are respectively provided with a left hand nut and a right hand nut. A screw rod having opposite thread on both ends is drivenly connected between the left hand nut and the right hand nut, and the middle portion of the screw rod is provided with a driven wheel. Alternatively, two screw rods having the same thread on both ends are drivenly connected between the left hand nut and the right hand nut. Each inner end of the two screw rods is provided with a conical driven gear arranged opposite to each other. A worm gear drivenly connected with a worm is fixedly connected with a conical main wheel. At this time, the axis of the motor is parallel to the movement direction of the left clamping frame and the right clamping frame. Because the worm gear drivenly connected with a worm is fixedly connected with a main driving wheel, adoption of this structure does not require the use of elastic members for clamping and restoration of position. In other embodiments, gears and the cooperation of screw rods and nuts can be used to achieve simultaneous drive or single drive of the left clamping frame and the right clamping frame. The transmission mode II realizes the two-way motion by the motor. Therefore, the racks need to be fixedly connected with the clamping frames. The transmission mode I realizes the motion of moving outward and opening by the motor and the motion of moving inward and closing by the elastic members. Therefore, the racks and the clamping frames need to be respectively slidably connected to the housing, and the adjacent end portions conflict with each other to achieve the motion transmission in the two directions of outward and inward. Preferably, a tension spring is used.
In other embodiments, the electric clamping bracket further includes a circuit board disposed in the housing, and a control device electrically connected with the circuit board. The control device includes an identification module, and a pressure switch disposed on the inner side of the left clamping frame and/or the right clamping frame. The pressure switch controls the drive motor to drive the left clamping frame or right clamping frame so that the left clamping frame and right clamping frame are far apart opposite to each other. Wherein, the pressure switch needs to be restarted after the mobile device is clamped, or to detect twice or more times of pulse signal in order to recognize them as control signals for picking up the mobile device. Or, by mean of feedback electric signals of the motor, the left clamping frame and the right clamping frame being pushed can be determined thereby recognizing it as a control signal for a user picking up the mobile device, wherein the movement of the left clamping frame and the right clamping frame will reversely drive the motor to rotate, thereby generating an electrical signal. This structure is suitable for the fixed connection between the left rack and the left clamping frame and between the right rack and the right clamping frame.
In other embodiments, the electric clamping bracket further includes a circuit board disposed in the housing, and a control device electrically connected with the circuit board. The control device includes an identification module and a press switch. When the identification module detects that a mobile device is approaching the housing, it controls the drive motor to drive the left clamping frame or the right clamping frame so that the left clamping frame and the right clamping frame are close to each other. When the press switch is pressed, it controls the drive motor to drive the left clamping frame or the right clamping frame so that the left clamping frame and the right clamping frame are far apart opposite to each other.
In other embodiments, the electric clamping bracket further includes a horizontally disposed left rack and a horizontally disposed right rack; the left rack and the right rack are respectively slidably connected to a housing; an output end of the drive motor is provided with a gear that is drivenly connected between the left rack and the right rack; when the drive motor drives the left rack and the right rack to move outward, the left rack and the right rack respectively press against the left clamping frame and the right clamping frame to move synchronously to both sides; the electric clamping bracket further includes a left elastic member and a right elastic member; the front end of the left elastic member presses against one end of the left clamping frame near the left rack, and the rear end of the left elastic member presses against the rear case; the front end of the right elastic member presses against one end of the right clamping frame near the right rack, and the rear end of the right elastic member presses against the rear case; when the drive motor forwardly drives the left rack and the right rack to move outward, the left rack and the right rack respectively press against inner ends of the left clamping frame and the right clamping frame so to synchronously move the two outward and apart; when the drive motor reversely drives the left rack and the right rack to move outward, the left clamping frame and the right clamping frame under the respective action of the elastic tension of the left elastic member and the right elastic member move inward and close together.
