The design of the reversal trigger block 832, that is, the reversal trigger block 832 is designed in the third housing 3, so that it can rotate as the third housing 3 is reversed. When the third housing 3 is in the third position (for example When it is housed horizontally on the second surface 12 of the first housing 1 )When the inversion trigger block 832 is in its initial state, the third power supply circuit of the third wireless charging unit 6 does not operate to supply power. When the inversion trigger block 832 rotates to the fourth position as the third housing 3 inverts, the inversion trigger block 832 rotates with it, triggering the first push-button switch 831, the third power supply circuit supplies power to the third wireless charging unit 6, and the third wireless charging unit 6 operates normally.

[0044] Referring to Figures 13, 14, and 15, Figure 13 shows a rotating swing arm 91 in a wireless charger according to one embodiment of the present invention. (For example, a plate) A schematic diagram illustrating this configuration is shown. Figure 14 shows a partially enlarged schematic diagram of C in Figure 13. Figure 15 shows a schematic diagram illustrating a second power supply protection assembly 9 in a wireless charger according to one embodiment of the present application. In some embodiments, the wireless charger further includes a second power supply protection assembly 9, and when the second housing 2 is in the first position, the second power supply protection assembly 9 shuts off the first power supply circuit of the first wireless charging unit 4. (For example, block, cut) do It is configured in such a way When the second housing 2 is in the second position, the second power supply protection assembly 9 conducts the first power supply circuit. It is configured in such a way ru.

[0045] In some embodiments, the second power supply protection assembly 9 includes a rotary swing arm 91 and a second push-button switch 92. A push-button communication groove 13 is provided on the first surface 11 of the first housing 1, and the rotary swing arm 91 is fixedly connected at one end to the second housing 2 and extends into the interior of the first housing 1 through the push-button communication groove 13 at the other end. The second push-button switch 92 is connected to the first power supply circuit and is located inside the first housing 1.

[0046] Referring to Figures 16 and 17, Figure 16 shows a schematic diagram of the rotating swing arm 91 in the initial position in a wireless charger according to one embodiment of the present invention.

A second trigger member 921 is provided on the side wall of the second push-button switch 92, and the second trigger member 921 is elastically connected to the second push-button switch 92 and can retract after being pressed. When the second housing 2 is in the first position, the rotary swing arm 91 is separated from the second push-button switch 92 and is in its initial position, the second push-button switch 92 is off, and the first power supply circuit is interrupted. When the second housing 2 is in the second position, the rotary swing arm 91 contacts the second trigger member 921 of the second push-button switch 92, the second push-button switch 92 is triggered and turned on, and the first power supply circuit is restored. Specifically, the rotary swing arm 91 is fixedly connected to the second housing 2 and changes position in accordance with the change in position of the second housing 2, thereby realizing triggering and control of the second push-button switch 92.

[0047] In a wireless charger, if the second housing 2 is housed on the first surface 11 of the first housing 1, if the operation of the coil of the first wireless charging unit 4 cannot be stopped in a timely manner, the coil of the first wireless charging unit 4 will overheat and burn out because its upper half is covered with a metallic medium. do The design of the rotating swing arm 91, that is, the design of the rotating swing arm 91 to be integrated with the second housing 2, allows it to be displaced as the second housing 3 rotates and moves. When the second housing 2 is in the first position, that is, when it is housed horizontally on the first surface 11 of the first housing 1, the rotating swing arm 91 is in its initial state, and the first power supply circuit of the first wireless charging unit 4 does not operate to supply power. When the rotating swing arm 91 rotates with the second housing 2 to the second position, the rotating swing arm 91 moves with it, triggering the second push-button switch, the first power supply circuit supplies power to the first wireless charging unit 4, and the first wireless charging unit 4 operates normally.

[0048] The wireless charger in this application has multiple operating states.

[0050] Referring to Figure 19, which shows a schematic diagram of a wireless charger according to one embodiment of the present invention when it is folded in half and stored. When the second housing 2 is in the second position and the third housing 3 is in the third position, the wireless charger is folded in half and stored. In this state, the second wireless charging unit 5 in the second housing 2 can perform wireless charging, the first wireless charging unit 4 in the first housing 1 can perform wireless charging, and the first wireless charging unit 4 and the second wireless charging unit 5 can perform wireless charging simultaneously.

[0051] Referring to Figure 20, which shows a schematic diagram of a wireless charger according to one embodiment of the present invention when it is folded in half and stored. When the second housing 2 is in the first position and the third housing 3 is in the fourth position, the wireless charger is folded in half and stored. In this state, the second wireless charging unit 5 in the second housing 2 can perform wireless charging, the third wireless charging unit 6 in the third housing 3 can perform wireless charging, and the second wireless charging unit 5 and the third wireless charging unit 6 can perform wireless charging simultaneously.

[0052] Referring to Figure 21, which shows a schematic diagram of a wireless charger according to one embodiment of the present application when it is not folded and stored. When the second housing 2 is in the second position and the third housing 3 is in the fourth position, the wireless charger is not folded and stored, i.e., fully unfolded. In this state, the first wireless charging unit 4 in the first housing 1 can perform wireless charging, the second wireless charging unit 5 in the second housing 2 can perform wireless charging, and the third wireless charging unit 6 in the third housing 3 can perform wireless charging. The first wireless charging unit 4, the second wireless charging unit 5, and the third wireless charging unit 6 can perform wireless charging simultaneously.
