It is necessary to install an additional energy storage device on the door for power supply. This form complicates the internal circuit layout of the door and increases the cost of the energy storage device.

[0034] Reference below Figure 1-Figure 2 A wireless power supply device 1 according to an embodiment of the present invention is described.

[0035] like Figure 1-Figure 2 As shown, the wireless power supply device 1 according to the present invention includes: a transmitting part 10, a receiving part 20, a detection member 30 and a driving member. The transmitting part 10 and the receiving part 20 are wirelessly connected for power supply and can selectively move relative to each other; the detection member 30 is suitable for detecting the movement of the transmitting part 10 or the receiving part 20 and sending a control signal; the driving member is suitable for driving the receiving part 20 or the transmitting part 10 to move according to the control signal to maintain the wireless connection state between the transmitting part 10 and the receiving part 20.

[0036] Specifically, the wireless connection between the transmitting part 10 and the receiving part 20 can realize the power supply to the receiving part 20 in the case of wireless beam connection. Here, since relative movement will occur between the transmitting part 10 and the receiving part 20, in order to ensure that the transmitting part 10 and the receiving part 20 always maintain a wireless connection state, the detection member 30 and the driving member are designed to design the transmitting part 10 and the receiving part 20 to be movable together, so that the angle and / or distance between the transmitting part 10 and the receiving part 20 always maintains a state in which the transmitting part 10 and the receiving part 20 can be wirelessly connected. More specifically, the detection member 30 is designed to detect the movement of one of the transmitting part 10 and the receiving part 20 relative to the other, and the driving member is designed to drive the other of the transmitting part 10 and the receiving part 20 to move together, so as to maintain the state in which the transmitting part 10 and the receiving part 20 are wirelessly connected, thereby ensuring continuous power supply.

[0037] The driving member is suitable for driving the receiving part 20 or the transmitting part 10 to move, so that the transmitting part 10 moves synchronously with the receiving part 20, thereby maintaining a continuous and stable wireless connection state between the transmitting part 10 and the receiving part 20. The relative movement form between the transmitting part 10 and the receiving part 20 and the type of the detecting member 30 can be selected according to actual needs, ensuring that the driving member can drive the other of the transmitting part 10 and the receiving part 20 to move together according to the control signal sent by the detecting member 30 to maintain the wireless connection state between the transmitting part 10 and the receiving part 20.

[0038] Furthermore, the driving component can drive the other of the transmitting part 10 and the receiving part 20 to move together with the transmitting part 10 and the receiving part 20 according to the control signal to a range where the transmitting part 10 and the receiving part 20 can be wirelessly connected, thereby ensuring continuous power supply to the receiving part 20. Alternatively, the driving component can drive the other of the transmitting part 10 and the receiving part 20 to move together with the transmitting part 10 and the receiving part 20 according to the control signal until the transmitting part 10 and the receiving part 20 always remain in a facing state, thereby enabling the transmitting part 10 and the receiving part 20 to maintain a good wireless connection effect, thereby ensuring stable power supply.

[0039] Furthermore, there is no need to limit the timing when the driver drives the other of the transmitting part 10 and the receiving part 20 to move together. It is sufficient to ensure that the driver can drive the other of the transmitting part 10 and the receiving part 20 to move together before the wireless connection between the transmitting part 10 and the receiving part 20 is disconnected. In some embodiments, the driver can drive the transmitting part 10 and the receiving part 20 to move at the same time to maintain the wireless connection between the transmitting part 10 and the receiving part 20, thereby ensuring that the power supply structure can continuously and stably supply power to the power-consuming structure.

[0040] The wireless power supply device 1 according to the present invention is designed with a detection component 30 and a driving component to realize that when one of the receiving part 20 and the transmitting part 10 moves, the other can move along with it, so that the transmitting part 10 and the receiving part 20 are always in a range that can maintain a wireless connection state, which is conducive to realizing the dewiring of the wireless power supply device 1 and improving the working stability and safety of wireless power supply.

The driving member drives the other of the transmitting part 10 and the receiving part 20 to rotate and / or translate according to the control signal, so that the transmitting part 10 and the receiving part 20 are in a range that can maintain a wireless connection state; in other embodiments, The transmitting part 10 and the receiving part 20 can translate relative to each other. Here, translation can refer to the transmitting part 10 and the receiving part 20 moving in a direction away from each other, or it can refer to the transmitting part 10 and the receiving part 20 translating in a certain plane. At this time, the detection part 30 can use a displacement sensor to detect the movement distance of one of the transmitting part 10 and the receiving part 20 relative to the other and send a control signal.

[0047] According to some embodiments of the present invention, Figure 1-Figure 2 As shown, the drive shaft 421 is arranged parallel to the pivot axis of the transmitting part 10 or the receiving part 20.
