Abstract

Disclosed are a wireless charging device and a notebook computer including the wireless charging device. The wireless charging device includes a device body, wherein further includes a charging board rotatablely connected with the device body; the charging board is provided with a charging-discharging coil; the device body is provided with a hollow for accepting the charging board; the hollow has a touch switch disposed therein for switching working circuit of the charging-discharging coil; the device body has a battery disposed therein and a charging circuit and a discharging circuit, both of which are connected with the battery; when the charging board is located inside the hollow, the charging-discharging coil is connected with the charging circuit so as to enter a charging mode; and when the charging board is located outside the hollow, the charging-discharging coil is connected with the discharging circuit so as to enter a discharging mode.

Claims

1. A wireless charging device, comprising a device body, wherein further comprises a charging board rotatablely connected with the device body;

the charging board is provided with a charging-discharging coil;

the device body is provided with a hollow for accepting the charging board;

the hollow has a touch switch disposed therein for switching working circuit of the charging-discharging coil;

the device body has a battery disposed therein and a charging circuit and a discharging circuit, both of which are connected with the battery;

when the charging board is located inside the hollow, the charging-discharging coil is connected with the charging circuit so as to enter a charging mode; and

when the charging board is located outside the hollow, the charging-discharging coil is connected with the discharging circuit so as to enter a discharging mode.

2. The wireless charging device according to claim 1, wherein the hollow has a locking element provided at a side thereof for locking the charging board, and the charging board has a locking hole formed thereon for corresponding to the locking element;

the locking element comprises a locking pin for sliding fit with the device body and a spring provided on inner end of the locking pin and a shifting part connected with outer side of the locking pin and extending to outer side of the device body; and

the device body is further provided with a sliding cavity for accepting the locking pin and a sliding groove and a recess for the shifting part to slide.

3. The wireless charging device according to claim 2, wherein further comprises a knockout pin disposed near the bottom of the hollow for sliding fit with the device body and the charging board is provided with a inclined surface for corresponding to the knockout pin;

and further comprises a driving lever located between the knockout pin and the locking pin, the driving lever being rotatablely connected with the device body, and having an upper end disposed inside a lower drive groove formed on the knockout pin and a lower end disposed inside an upper drive groove formed on the knockout pin.

4. The wireless charging device according to claim 3, wherein when leaving the locking hole, the locking pin transmits driving force to the driving lever via the upper drive groove, the driving lever then pushes the knockout pin to apply force to the inclined surface so that the charging board is pushed out of the hollow;

and there is a gap provided between the upper drive groove and the lower end of the driving lever, the gap being equal to or larger than a needed displacement when the locking pin leaving the locking hole.

5. The wireless charging device according to claim 1, wherein the device body is a tablet computer.

6. A notebook computer, comprising a computer body, wherein further comprises a charging board rotatablely connected with the computer body;
