Abstract

A wireless charging apparatus includes a first body, a second body and a plug unit. The first body has a placement area on surface and a charging module inside. The charging module is located correspondingly to placement area and includes at least a transmitting induction coil and a control circuit unit. The second body is coupled to first body on one side. When flipped open, the two bodies form an angle, and the placement area is horizontal so as to place electronic device on placement area. The plug unit is on second body, located at back of second body facing away from first body. The plug unit includes at least two metal insertion elements, electrically connected to charging module internally. As such, when in use, the plug unit is plugged into wall socket, and the electronic device is placed on placement area of first body for wireless charging.

Claims

1. A wireless charging apparatus, comprising:

a first body, a second body and a plug unit;

wherein the first body having a placement area on a surface, and having a charging module inside the first body;

the charging module being located at a location corresponding to the placement area and having at least a transmitting induction coil and a control circuit unit;

the second body having a side coupled to the first body;

when flipped open, the first body and the second body forming an angle, and the placement area of the first body being along the horizontal direction so that an electronic device able to placed on the placement area; and

the plug unit being disposed on the second body, located at back of the second body facing away from the first body;

the plug unit having at least two metal insertion elements;

the metal insertion elements being electrically connected to the charging module inside the first body through internal path.

2. The wireless charging apparatus as claimed in claim 1, wherein the plug unit further comprises a plurality of trenches, with each trench corresponds to a metal insertion element;

the metal insertion element is partially coupled to the inner wall of the trench, and can be housed inside the trench when flipped.

3. The wireless charging apparatus as claimed in claim 2, wherein the plug unit further comprises a rotatable element, the plurality of trenches is located at rotatable element and the metal insertion elements are partially coupled to the plurality of trenches at the rotatable element;

the rotatable element is disposed on the second body, located on a same side as the plug unit, and the rotatable element can change the orientation of the metal insertion elements by rotation.

4. The wireless charging apparatus as claimed in claim 3, wherein the rotatable element can rotate between 0°

-90°

.

5. The wireless charging apparatus as claimed in claim 1, wherein the first body and the second body can press tightly against each other than folded, and can be expanded to form an angle preferably between 85°

-95°

.

6. The wireless charging apparatus as claimed in claim 1, wherein the coupling of the first body and the second body demonstrates a rigidity so that when an external force applied to adjust the angle between the two bodies vanishes, the two bodies maintain the adjusted angle.

7. The wireless charging apparatus as claimed in claim 1, wherein the second body further comprises at least a stop element, partially coupled to the second body and located on a same side as the plug unit;

and the stop element, after flipped, protrudes above the surface of the second body.
