The wireless keyboard is designed to meet the operation habits of both left and right handicaps and can be placed and charged by the discharge coils of the corresponding desk pad, and the improvement of the wireless keyboard is needed.

In view of the above, the present utility model has been made in view of the above-described drawbacks of the prior art, and an object of the present utility model is to solve the above-described problems by intensively studying and applying the same in combination with the theory.

As used herein, terms such as "first," "second," "third," "fourth," and "fifth," etc., describe various elements, components, regions, layers and/or sections that are not limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another. Unless the context clearly indicates otherwise, terms such as "first", "second", "third", "fourth" and "fifth" as used herein do not imply a sequence or order.

The detailed description and technical content of the present utility model will be described below with reference to the drawings, which are, however, for illustrative purposes only and are not intended to limit the present utility model.

The utility model provides a wireless charging keyboard which is used for being matched with a desk pad A with a wireless charging function. The desk pad A is provided with a charging area A1 provided with a discharging coil. Referring to fig. 1 to 5, the wireless charging keyboard of the present utility model mainly includes a keyboard body 10, a first induction coil 20, a second induction coil 30 and a charging circuit 40.

The keyboard body 10 includes a housing 11 and a plurality of keys 12. The keyboard body 10 has an accommodating space 13 therein. Each key 12 is arranged on the casing 11 in a pressing manner for the user to press.

The first induction coil 20 is disposed in the accommodating space 13. The second induction coil 30 is disposed in the accommodating space 13 and is spaced apart from the first induction coil 20. Specifically, in the present embodiment, the first induction coil 20 is located at one side of the accommodating space 13, and the second induction coil 30 is located at the other side opposite to the accommodating space 13, but the present utility model is not limited thereto, and the first induction coil 20 and the second induction coil 30 may be disposed at a distance other than adjacent to each other.

The charging circuit 40 is disposed in the accommodating space 13, and the charging circuit 40 is electrically connected to the first induction coil 20 and the second induction coil 30. The charging circuit 40 at least includes a circuit board 41 and a circuit 42, but the utility model is not limited thereto, and for example, the charging circuit 40 in the present embodiment further includes a power storage unit 43 electrically connected to the circuit board 41 and the circuit 42 for storing power for use, wherein the power storage unit 43 may be a battery or a capacitor. The circuit 42 is electrically connected to the circuit board 41, the first induction coil 20 and the second induction coil 30, so that the power generated by the electromagnetic induction of the first induction coil 20 and the second induction coil 30 can be transmitted to the circuit board 41 via the circuit 42.

Therefore, the first induction coil 20 and the second induction coil 30 are disposed in the accommodating space 13 at intervals and not adjacent to each other, so that the wireless charging keyboard of the utility model can have two induction coil areas capable of performing wireless charging to be placed corresponding to the charging area A1 of the table pad a, and thus can be simultaneously suitable for use in the habit of left-handed or right-handed users for placement and charging.

Specifically, please refer to fig. 4 and 5, which illustrate a usage state diagram (one) and a usage state diagram (two) of the present utility model. When the wireless charging keyboard of the present utility model is used by a right-handed person, a wireless mouse B is disposed on the right side of the wireless charging keyboard, and the wireless mouse B and the first induction coil 20 are both disposed in the charging area A1 of the table pad a for simultaneous charging and use, as shown in fig. 4. When the wireless charging keyboard of the present utility model is used by a left-handed person, the wireless mouse B is disposed on the left side of the wireless charging keyboard, and the wireless mouse B and the second induction coil 30 are still disposed in the charging area A1 of the table pad a, so that the wireless charging keyboard can be used for charging at the same time, as shown in fig. 5.

Further described, the wireless charging keyboard of the present utility model further comprises at least one switching element 50. The switching element 50 is electrically connected to the line 42, and is capable of switching the communication between the line 42 and the first induction coil 20 or the second induction coil 30. In the present embodiment, the number of the switching elements 50 is two, and the switching elements are respectively a mechanical switch and a microcontroller (MCU, microcontroller Unit) and are respectively disposed on the keyboard body 10 and the circuit board 41, but the present utility model is not limited thereto, and only one switching element 50 may be disposed. Specifically, the mechanical switch is disposed on the keyboard body 10, and the microcontroller is disposed on the circuit board 41. Therefore, the user can switch the communication between the line 42 and the first induction coil 20 or the second induction coil 30 by pulling or pressing the mechanical switch, or can automatically switch the communication between the line 42 and the first induction coil 20 or the second induction coil 30 by detecting the microcontroller, so as to avoid the first induction coil 20 or the second induction coil 30 from affecting the other induction coil during charging.

Referring back to fig. 1 to 3, the wireless charging keyboard of the present utility model further comprises an electrical connector 60. The electrical connector 60 is disposed on the keyboard body 10 and electrically connected to the charging circuit 40.
