For example, the first object can be one or multiple. In addition, "and/or" in the description and claims indicates at least one of the connected objects, and the character "/" generally indicates that the related objects are in an "or" relationship.

The wireless charging stand and wireless charging device provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios.

Referring to FIGS. 1 to 8 , an embodiment of the present application discloses a wireless charging stand. The disclosed wireless charging stand includes a device body 100 , an electromagnetic coil 200 , an action switch 600 and a pressure-bearing member 300 . Among them, the equipment main body 100 serves as the installation basis for the electromagnetic coil 200 and the pressure-bearing part 300. The electromagnetic coil 200 and the pressure-bearing part 300 The pressing parts 300 are all arranged on the device body 100. When the electromagnetic coil 200 is energized, the electromagnetic coil 200 generates magnetic attraction, and the wireless charging stand can absorb the electronic device.

The pressure-bearing member 300 is movable relative to the equipment body 100, and at least part of the action switch 600 is connected to the pressure-bearing member 300. Therefore, at least part of the action switch 600 follows the movement of the pressure-bearing member 300, and at least part of the movement of the action switch 600 can be Switches the state of the electromagnetic coil 200. Specifically, the pressure-bearing member 300 moves between the first position and the second position relative to the equipment body 100 , the pressure-bearing member 300 can rotate relative to the equipment body 100 , and at least part of the action switch 600 can follow the pressure-bearing member 300 to rotate. ; The pressure-bearing member 300 can also move relative to the equipment body 100, and at least part of the action switch 600 can follow the movement of the pressure-bearing member 300. Alternatively, a part of the action switch 600 can be connected to the pressure-bearing member 300, and the other part of the action switch 600 can be fixed relative to the device body 100. When the pressure-bearing member 300 moves, it drives a part of the action switch 600 to move; the pressure-bearing member 300 can Connected to the entirety of the action switch 600, when the pressure-bearing member 300 moves, it drives the overall movement of the action switch 600. In short, when the pressure-bearing member 300 moves, it drives at least part of the movement of the action switch 600, so that the action switch 600 switches between the electrically conductive state and the electrically disconnected state, and further switches the electromagnetic coil 200 between the energized state and the deenergized state. .

When the pressure-bearing member 300 is in the first position, the action switch 600 is electrically turned on, so that the electromagnetic coil 200 is in the energized state; when the pressure-bearing member 300 is in the second position, the action switch 600 is electrically turned off, so that the electromagnetic coil 200 is in the energized state. The electromagnetic coil 200 is in a power-off state. In this embodiment, when the pressure-bearing member 300 is in the first position, it means that the pressure-bearing member 300 bears the pressure of the electronic device. At this time, the action switch 600 is electrically conductive and the electromagnetic coil 200 is energized to generate magnetic attraction. The charging stand can absorb electronic devices and keep the relative position of the electronic device and the wireless charging stand fixed, which helps the electronics to be accurately in the charging position and ensures the effective charging process. When the pressure-bearing member 300 is in the second position, it means that the pressure-bearing member 300 does not bear the pressure of the electronic device. Specifically, after the electronic device is charged, when the user takes the electronic device, the manual force gradually Overcoming the gravity of the electronic device, the pressure-bearing member 300 switches from the pressurized state to the unpressurized state. The pressure-bearing member 300 leaves the first position and moves to the second position. The action switch 600 also switches to the electrically disconnected state. At this time The electromagnetic coil 200 is in a power-off state, and the magnetic attraction disappears, and the electronic device will no longer be attracted. Therefore, the electronic device and the wireless charging stand can be separated directly, and there is no need to manually apply a large force to separate the wireless charging stand and the electronic device. , simplifying the operation process, making the wireless charging stand more convenient to use, and improving the user experience.

In an optional embodiment, the electromagnetic coil 200 is a magnetic adsorption coil, and the wireless charging base further includes a charging coil. The charging coil and the electromagnetic coil 200 are powered on or off at the same time. When the charging coil is in the powered state, state, the wireless charging base charges the electronic device. At this time, charging and adsorbing the electronic device are implemented by different coils, and the state of the charging coil can change with the state of the electromagnetic coil 200, thereby disconnecting when charging is not needed. charging coil to reduce the energy consumption of the wireless charging stand. In another optional embodiment, the electromagnetic coil 200 is a charging coil. In this way, switching the state of the electromagnetic coil 200 during the movement of the pressure-bearing member 300 can not only control whether the wireless charging base absorbs the electronic device, but also controls whether the wireless charging base charges the electronic device, preventing the electronic device from being separated from the wireless charging base and causing electromagnetic interference.
