In the present invention, the main body of the wireless charging device is composed of a base body 100 and a movable support member 200 , the base body 100 is provided with a receiving slot 110 , and the movable support member 200 is movably installed in the storage slot 110 . It should be noted that the first end 210 and the second end 220 are not limited to the end surfaces of the movable support member 200 , but refer to the solid parts of the movable support member 200 close to the two end surfaces, and the movable support member 200 passes through the support position of the first end 210 . 211 supports the device to be charged, and is movably connected to the storage slot 110 through the second end 220, so that the movable support 200 has a use state and a storage state. In the storage state, the movable support 200 is stored in the storage slot 110, and in use In the state, the support position 211 of the movable support member 200 can be exposed outside the receiving slot 110 .

Without loss of generality, in this embodiment, when the movable support member 200 is in the storage state, the movable support member 200 can be switched to the use state by pulling the movable support member 200 outward in the storage slot 110 . In other embodiments, the movable support 200 can also be connected to the base body 100 by pressing the buckle. When the movable support 200 is in the storage state, the movable support 200 can be pressed to pop up; when the movable support 200 is in use In the state, the movable support 200 can be pressed until it is accommodated in the receiving slot 110 .

In the technical solution of the present invention, the movable support 200 in the wireless charging device is movably connected to the storage slot 110, so that the support position 211 on the movable support 200 can enter and exit the storage slot 110. When the wireless charging device needs to be used for charging When the device is charging, the movable support 200 can be pulled and switched to the use state, so that the support position 211 is exposed to the receiving slot 110, and the device to be charged can be placed on the support position 211, so that the wireless charging device can use the charging The module charges the device to be charged; and after the charging is completed, the movable support 200 can be pushed until the support position 211 is received in the storage slot 110, so that the movable support 200 is switched to the storage state, thereby reducing the size of the wireless charging device Therefore, the volume of the wireless charging device can be much smaller than the existing integrated wireless charging device, which is convenient for users to store or carry out.

Further, in this embodiment, as shown in FIGS. 5 and 6 , the base body 100 is provided with two guide ribs 111 arranged in parallel in the receiving groove 110 , and the guide ribs 111 face the receiving groove 110 . The groove 110 extends in the direction of the notch, and the second end 220 is slidably connected between the two guide ribs 111 . On the one hand, the guide ribs 111 can guide the movable support 200 when the movable support 200 is pushed into or pulled out of the receiving slot 110 . The ribs 111 can also limit the movable support 200 to limit the movable support 200 from shifting in the storage slot 110 , so that the movable support 200 cannot be pulled out from the storage slot in the next use.

Further, in this embodiment, as shown in FIG. 3 and FIG. 4 , the second end 220 is sleeved with a damping limiting ring 221 , and the damping limiting ring 221 abuts against the guide rib 111 to The second end 220 is connected between the two guide ribs 111 in a damping sliding manner. The damping limiting ring 221 elastically abuts between the guide rib 111 and the second end 220 of the movable support member 200 to limit the movement of the movable support member 200 in the extending direction of the guide rib 111 , if the external force is not large enough to resist When damping the damping force of the limiting ring 221 , the movable support 200 will remain in the original position. Therefore, the movable support 200 will not easily come out of the receiving groove 110 . In addition, in the use state, the supporting position 211 is exposed outside the receiving groove 110 . When the movable support member 200 is not easily retracted into the receiving groove 110 . Therefore, the damping limiting ring 221 can stably maintain the movable support 200 in the storage state or the use state, so that the user can conveniently store, carry or use the wireless charging device.

Further, in this embodiment, as shown in FIG. 3 , the second end 220 is provided with a limit ring groove 222 , and the damping limit ring 221 is clamped in the limit ring groove 222 . The limiting ring groove 222 can limit the damping limiting ring 221 to prevent the damping limiting ring 221 from shifting or even falling off on the movable support 200 , so as to ensure the effect of the damping limiting ring 221 on the movable support 200 . Of course, in other embodiments, it is also possible that the second end 220 is provided with a plurality of limit locking protrusions, and the damping limit ring 221 is correspondingly provided with limit holes. The installation position of the limit damping limit ring 221 on the movable support 200 .

Further, in this embodiment, as shown in FIG. 1 and FIG. 3 , the support position 211 is provided with a limit groove 212 , and in the use state, the limit groove 212 is used for the waiting Charging device limit card setting. When the volume of the device to be charged is relatively small, for example, when the device to be charged is a mobile phone, it can be clamped in the limiting groove 212. In this way, the device to be charged can be relatively fixed to the movable support 200 so that it can be Stable charging on the wireless charging device. Of course, in other embodiments, the seat body 100 may also be provided with a limiting groove, which can also limit the position of the device to be charged when it is being charged.

Further, in this embodiment, as shown in FIG. 1 and FIG. 3 , the bottom of the first end 210 is provided with a first supporting protrusion 213 . Because the movable support 200 needs to be accommodated in the receiving groove 110, and in this embodiment, the bottom wall of the receiving groove 110 has a certain thickness. 200 cannot touch the table, and when the device to be charged is placed on the support position 211 , the movable support 200 will exert force on the receiving slot 110 , which may damage the connection stability of the movable support 200 and the base 100 in the long run. In this embodiment, the bottom of the first end 210 of the movable support member 200 is provided with the first support protrusion 213 . Therefore, when the movable support member 200 is exposed outside the receiving groove 110 , the movable support member 200 can pass through the first support protrusion 213 is in contact with the table. When the device to be charged is placed on the support position 211, the movable support 200 can also be supported by the table, and will not generate excessive force on the base 100, which is beneficial to ensure the movable support 200 and the storage. The connection stability between the grooves 110. Of course, in other embodiments, the movable supporting member 200 may not be provided with the first supporting protrusion 213, and the receiving slot 110 may not be provided with a bottom wall, and the bottom wall of the movable supporting member 200 and the bottom wall of the base body 100 may be at the same level.

After the user places the smart glasses on the wireless charging device, the charging switch can be turned on, so that the transmitting coil 400 starts to discharge and the wireless charging device starts charging The smart glasses are wirelessly charged; when the charging is completed, the user can turn off the charging switch, so that the transmitting coil 400 stops discharging.

The above descriptions are only optional embodiments of the present invention, and are not intended to limit the scope of the present invention. Under the inventive concept of the present invention, any equivalent structural transformations made by using the contents of the description and drawings of the present invention, or direct/indirect Applications in other related technical fields are included in the scope of patent protection of the present invention.
