Referring to fig. 1, fig. 2, fig. 3 and fig. 4, the wireless charger 1000 of the present embodiment may be used to charge the electronic device 500. When performing wireless charging, the electronic device 500 is placed on the wireless charger 1000. The wireless charger 1000 includes a clamping assembly 100. The clamping assembly 100 includes a floating plate 10, a clamping mechanism 20, and a clamping plate 30. The floating plate 10 is used to set the electronic device 500, and the floating plate 10 can move by the gravity of the electronic device 500. The chucking mechanism 20 rotates when the floating plate 10 moves.

The clamping assembly 100 and the wireless charger 1000 of the embodiment of the present application enable the floating plate 10 to move by using the gravity action of the electronic device 500, so as to drive the clamping mechanism 20 and the clamping plate 30 to rotate to enable the clamping plate 30 to clamp the electronic device 500, enable the electronic device 500 to be located at a preset position so that the electronic device 500 is aligned with the wireless charger 1000, and further improve the charging efficiency of the wireless charger 1000.

It is understood that the electronic device 500 of the embodiment of the present application includes, but is not limited to, a mobile terminal such as a mobile phone, a tablet, or other portable electronic devices, and the electronic device 500 is taken as an example and described herein.

Specifically, referring to fig. 1 and fig. 2 together, fig. 1 and fig. 2 are schematic diagrams of the wireless charger 1000 in an unused state. The wireless charger 1000 includes a clamping assembly 100, the clamping assembly 100 including a floating plate 10. When the wireless charger 1000 is in an unused state, the floating plate 10 is in a freely stretched state. Referring to fig. 3 and 4 together, fig. 3 and 4 are schematic views of the wireless charger 1000 in a use state. When the wireless charger 1000 is in a use state, the electronic device 500 is placed on the wireless charger 1000, and the floating plate 10 is moved downward by the self-weight of the electronic device 500. When the floating plate 10 moves downward, the clamping mechanism 20 and the clamping plate 30 are driven to rotate so that the clamping plate 30 clamps the electronic device 500. Thus, the electronic device 500 is located at a predetermined position so that the electronic device 500 and the wireless charger 1000 are aligned, thereby improving the charging efficiency of the wireless charger 1000. It should be noted that the preset position may refer to a centering position of a charging coil of the electronic device 500 to a charging coil of the wireless charger 1000, so that the electronic device 500 and the wireless charger 1000 are aligned by using the self weight of the electronic device 500, and the charging efficiency of the wireless charger 1000 may be improved.
