Example 1: a wireless charger and an intelligent automatic alignment system of an automobile with a movable base are shown in figures 1, 3 and 4 and comprise a wireless charger arranged on the ground and aconvex receiver 1 arranged on anautomobile 2. The wireless charger includes abase 3, and awireless transmitter 5 disposed on thebase 3. A wireless transmitting coil is arranged in thewireless transmitter 5. The bottom of thebase 3 is provided with afixing part 28 which can move relative to thebase 3. Thebase 3 is provided with apositioning recess 26. The fixingportion 28 is provided with apositioning projection 27 which is fitted with thepositioning recess 26. A moving mechanism is arranged in thebase 3. The moving mechanism is connected to the fixedportion 28. Thewireless transmitter 5 is also provided with a controller and adistance sensor 6. The controller is electrically connected to thedistance sensor 6. The controller is electrically connected with the moving mechanism. Since thereceiver 1 protrudes from the vehicle cabin, the distance from thewireless transmitter 5 to thereceiver 1 is less than the distance from thewireless transmitter 5 to the bottom of theautomobile 2, and whether thereceiver 1 is located above thewireless transmitter 5 can be detected by thedistance sensor 6. Thedistance sensor 6 may be a distance sensor or an opto-electronic switch or a proximity switch or an ultrasonic distance measuring sensor.

The moving mechanism comprises twolead screw 7fixing seats 8 which are arranged in thebase 3 and are respectively and fixedly connected with thebase 3. Arotatable screw rod 7 is arranged between the twoscrew rod 7 fixing seats 8. One end of thescrew rod 7 is provided with afirst motor 18, and thescrew rod 7 is in transmission connection with the motor. Thescrew 7 is also sleeved with ascrew 7nut 9. Thebase 3 is provided with an opening, and thescrew 7 and thenut 9 penetrate through the opening to be fixedly connected with the fixingpart 28. The controller is electrically connected to thefirst motor 18.

Thedistance sensor 6 is provided in the center of the wireless charger.

Theproximity switch 14 is provided to prevent the wireless charger from colliding with the tires of theautomobile 2 when the wireless charger is moved laterally.

The use of this embodiment is as follows: the moving mechanism drives thebase 3 to move transversely relative to the lifting device. The lifting device and thebase 3 are fixed on the ground, when theautomobile 2 is stopped stably, the position of thebase 3 relative to theautomobile 2 is fixed, and the moving mechanism drives thebase 3 to move transversely relative to theautomobile 2. Thedistance sensor 6 can sense the relative position of thewireless transmitter 5 and thereceiver 1 on theautomobile 2, and when the left edge of thereceiver 1 is detected, namely the distance detected by thedistance sensor 6 suddenly becomes smaller and the reduction amount is approximately equal to the protrusion amount of thereceiver 1 when the left edge moves rightwards, or the distance detected by thedistance sensor 6 suddenly becomes larger and the increase amount is approximately equal to the protrusion amount of thereceiver 1 when the left edge moves leftwards, thewireless transmitter 5 is enabled to move rightwards for a distance, so that the horizontal distance between thewireless transmitter 5 and thereceiver 1 is within an error range. When detecting the right edge of thereceiver 1, that is, when moving to the left, the distance detected by thedistance sensor 6 suddenly becomes smaller and decreases by an amount approximately equal to the protrusion amount of thereceiver 1, or when moving to the right, the distance detected by thedistance sensor 6 suddenly becomes larger and increases by an amount approximately equal to the protrusion amount of thereceiver 1, thewireless transmitter 5 is moved to the left by a distance such that the horizontal distance between thewireless transmitter 5 and thereceiver 1 is within the error range.

Example 2: as shown in fig. 2, the difference between the mobile mechanism and theembodiment 1 is that the mobile mechanism includes arack 16 disposed in abase 3 and fixedly connected to thebase 3.

Both ends of thetiming belt 22 are fixedly connected to the fixingportion 28. The driving pulley 23 is connected with a third motor. The third motor is arranged in thebase 3 and is fixedly connected with thebase 3. The driven pulley 24 is disposed in thebase 3 and rotatably connected to thebase 3. Thesynchronous belt 22 is sleeved outside the driving pulley 23 and the driven pulley 24.

Example 4: as shown in fig. 5 to 6, the difference between the mobile wireless charger and the intelligent automatic alignment system for automobiles and theembodiment 1, 2 or 3 is that aprotection board 21 is disposed above thewireless transmitter 5. Theprotection plate 21 is fixedly connected with thebase 3. The number of thedistance sensors 6 is two, and the two distance sensors are respectively arranged at the top of thewireless transmitter 5 and at two ends along the translation direction of the moving mechanism.

The use of this embodiment is as follows: thedistance sensor 6 can sense the relative position of thewireless transmitter 5 and thereceiver 1 on theautomobile 2, when thedistance sensor 6 positioned on the left side of thewireless transmitter 5 detects the left edge of thereceiver 1, namely, when the distance detected by thedistance sensor 6 suddenly becomes smaller and the reduction amount is approximately equal to the protruding amount of thereceiver 1 when the distance moves rightwards, or when the distance detected by thedistance sensor 6 suddenly becomes larger and the increase amount is approximately equal to the protruding amount of thereceiver 1 when the distance moves leftwards, thewireless transmitter 5 is enabled to move rightwards for a distance, so that the horizontal distance between thewireless transmitter 5 and thereceiver 1 is within an error range. When thedistance sensor 6 located at the right side of thewireless transmitter 5 detects the right edge of thereceiver 1, that is, the distance detected by thedistance sensor 6 suddenly decreases and decreases by an amount approximately equal to the amount of protrusion of thereceiver 1 when moving to the left or the distance detected by thedistance sensor 6 suddenly increases and increases by an amount approximately equal to the amount of protrusion of thereceiver 1 when moving to the right, thewireless transmitter 5 is moved to the left by a distance such that the horizontal distance between thewireless transmitter 5 and thereceiver 1 is within an error range.
