It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "bottom" and "top," "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
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 a convex receiver 1 arranged on an automobile 2. The wireless charger includes a base 3, and a wireless transmitter 5 disposed on the base 3. A wireless transmitting coil is arranged in the wireless transmitter 5. The bottom of the base 3 is provided with a fixing part 28 which can move relative to the base 3. The base 3 is provided with a positioning recess 26. The fixing portion 28 is provided with a positioning projection 27 which is fitted with the positioning recess 26. A moving mechanism is arranged in the base 3. The moving mechanism is connected to the fixed portion 28. The wireless transmitter 5 is also provided with a controller and a distance sensor 6. The controller is electrically connected to the distance sensor 6. The controller is electrically connected with the moving mechanism. Since the receiver 1 protrudes from the vehicle cabin, the distance from the wireless transmitter 5 to the receiver 1 is less than the distance from the wireless transmitter 5 to the bottom of the automobile 2, and whether the receiver 1 is located above the wireless transmitter 5 can be detected by the distance sensor 6. The distance 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 two lead screw 7 fixing seats 8 which are arranged in the base 3 and are respectively and fixedly connected with the base 3. A rotatable screw rod 7 is arranged between the two screw rod 7 fixing seats 8. One end of the screw rod 7 is provided with a first motor 18, and the screw rod 7 is in transmission connection with the motor. The screw 7 is also sleeved with a screw 7 nut 9. The base 3 is provided with an opening, and the screw 7 and the nut 9 penetrate through the opening to be fixedly connected with the fixing part 28.

The proximity switch 14 is provided to prevent the wireless charger from colliding with the tires of the automobile 2 when the wireless charger is moved laterally.
The use of this embodiment is as follows: the moving mechanism drives the base 3 to move transversely relative to the lifting device. The lifting device and the base 3 are fixed on the ground, when the automobile 2 is stopped stably, the position of the base 3 relative to the automobile 2 is fixed, and the moving mechanism drives the base 3 to move transversely relative to the automobile 2. The distance sensor 6 can sense the relative position of the wireless transmitter 5 and the receiver 1 on the automobile 2, and when the left edge of the receiver 1 is detected, namely the distance detected by the distance sensor 6 suddenly becomes smaller and the reduction amount is approximately equal to the protrusion amount of the receiver 1 when the left edge moves rightwards, or the distance detected by the distance sensor 6 suddenly becomes larger and the increase amount is approximately equal to the protrusion amount of the receiver 1 when the left edge moves leftwards, the wireless transmitter 5 is enabled to move rightwards for a distance, so that the horizontal distance between the wireless transmitter 5 and the receiver 1 is within an error range. When detecting the right edge of the receiver 1, that is, when moving to the left, the distance detected by the distance sensor 6 suddenly becomes smaller and decreases by an amount approximately equal to the protrusion amount of the receiver 1, or when moving to the right, the distance detected by the distance sensor 6 suddenly becomes larger and increases by an amount approximately equal to the protrusion amount of the receiver 1, the wireless transmitter 5 is moved to the left by a distance such that the horizontal distance between the wireless transmitter 5 and the receiver 1 is within the error range.
Example 2: as shown in fig. 2, the difference between the mobile mechanism and the embodiment 1 is that the mobile mechanism includes a rack 16 disposed in a base 3 and fixedly connected to the base 3.

The protection plate 21 is fixedly connected with the base 3. The number of the distance sensors 6 is two, and the two distance sensors are respectively arranged at the top of the wireless transmitter 5 and at two ends along the translation direction of the moving mechanism.
The use of this embodiment is as follows: the distance sensor 6 can sense the relative position of the wireless transmitter 5 and the receiver 1 on the automobile 2, when the distance sensor 6 positioned on the left side of the wireless transmitter 5 detects the left edge of the receiver 1, namely, when the distance detected by the distance sensor 6 suddenly becomes smaller and the reduction amount is approximately equal to the protruding amount of the receiver 1 when the distance moves rightwards, or when the distance detected by the distance sensor 6 suddenly becomes larger and the increase amount is approximately equal to the protruding amount of the receiver 1 when the distance moves leftwards, the wireless transmitter 5 is enabled to move rightwards for a distance, so that the horizontal distance between the wireless transmitter 5 and the receiver 1 is within an error range. When the distance sensor 6 located at the right side of the wireless transmitter 5 detects the right edge of the receiver 1, that is, the distance detected by the distance sensor 6 suddenly decreases and decreases by an amount approximately equal to the amount of protrusion of the receiver 1 when moving to the left or the distance detected by the distance sensor 6 suddenly increases and increases by an amount approximately equal to the amount of protrusion of the receiver 1 when moving to the right, the wireless transmitter 5 is moved to the left by a distance such that the horizontal distance between the wireless transmitter 5 and the receiver 1 is within an error range.
