Detailed Description

To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

As shown in fig. 1, in one embodiment, a power adapter 10 is provided, wherein the power adapter 10 can be connected between an electronic device and a power socket so that the electronic device and the power socket are electrically connected, thereby enabling the power socket to charge the electronic device through the power adapter 10. The electronic device can be a mobile phone, a tablet, a watch, an earphone or a computer.

As shown in fig. 1 and 3, in one embodiment, the power adapter 10 includes a body 100, a first pin 200, and a second pin 300. It is understood that the power adapter 10 may further include a third pin, a fourth pin, etc. according to actual needs. The first and

second pins

200 and 300 are rotatably coupled to the body 100 such that the first and

second pins

200 and 300 have first and second states.

As shown in fig. 1, the first and

second pins

200 and 300 each have a free end and a connection end. The first and

second pins

200 and 300 are connected to the body 100 through connection ends. In the first state, the first pin 200 and the second pin 300 are respectively attached to the body 100 in opposite directions, and the connection ends of the first pin 200 and the second pin 300 are in contact, and the free ends face opposite directions. It is understood that when the first pin 200 and the second pin 300 are attached to the body 100, there may be a gap between the first pin 200 and the body 100 and between the second pin 300 and the body 100, for example, 1mm to 10mm, or greater than 10mm, that is, the first pin 200 and the second pin 300 are substantially attached to the body 100. There may also be a gap between the connection ends of the first pin 200 and the second pin 300, for example, 1mm to 10mm, or more than 10mm, that is, the connection ends of the first pin 200 and the second pin 300 are approximately in contact.

As shown in fig. 3, in the second state, the first pin 200 and the second pin 300 protrude from the body 100, for example, the first pin 200 is perpendicular or approximately perpendicular to the outer surface of the body 100, and the second pin 300 is perpendicular or approximately perpendicular to the outer surface of the body 100. When the outer surface of the body 100 is a curved surface, the first pin 200 and the second pin 300 protrude from the body 100 substantially along the normal line of the outer surface of the body 100 at the first pin 200 and the second pin 300. In the second state, the first pin 200 and the second pin 300 can be inserted into the power socket, and the body 100 may be provided with an interface, which can be electrically connected to both the first pin 200 and the second pin 300. The electronic device can be electrically connected to the interface, so that the power socket can charge the electronic device.

It will be appreciated that in the second state, as shown in figure 2, the first and

second prongs

200, 300 are spaced apart such that the first and

second prongs

200, 300 can be inserted into a conventionally provided electrical outlet. In the first state, the connection ends of the first and

second pins

200 and 300 are substantially in contact, and in the second state, the first and

second pins

200 and 300 are spaced apart. That is, there is a process in which the first and

second pins

200 and 300 are moved away from each other so that a gap can exist between the first and

second pins

200 and 300.

As shown in fig. 2, in one embodiment, the first pin 200 and the second pin 300 have a third state. In the third state, the first pin 200 and the second pin 300 are respectively and approximately attached to the body 100 in opposite directions, and a gap exists between the connection ends of the first pin 200 and the second pin 300. In the first state, a user may apply opposing forces to the first and

second pins

200 and 300, causing the first and

second pins

200 and 300 to move apart, thereby causing the first and

second pins

200 and 300 to switch to the third state. The user may then rotate the first and

second pins

200 and 300 such that the first and

second pins

200 and 300 are in the second state.

As shown in FIG. 1, in one embodiment, the power adapter 10 has two perpendicular X, Y and Z directions. The power adapter 10 is arranged along the X-axis in the width direction, along the Y-axis in the length direction, and along the Z-axis in the thickness direction. The body 100 includes a first surface 101 and a second surface (not shown) disposed opposite to each other, and a first side surface 103 and a second side surface 104 disposed opposite to each other. The first surface 101 and the second surface define a thickness of the power adapter 10, and the first side 103 and the second side 104 define a width of the power adapter 10.

As shown in fig. 1, in an embodiment, in the first state, the free ends of the first pins 200 and the second pins 300 are flush with the first side surface 103 and the second side surface 104, respectively, so that the first pins 200 do not protrude from the first side surface 103, and the second pins 300 do not protrude from the second side surface 104. The sum L1 of the dimensions of the first pins 200 and the second pins 300 in the X direction is the width of the power adapter 10, and the width of the power adapter 10 is smaller.

As shown in fig. 2, in an embodiment, in the third state, the free ends of the first pins 200 and the second pins 300 protrude from the first side surface 103 and the second side surface 104, respectively. In the third state, the gap between the connection ends of the first and

second pins

200 and 300 is L3, and in the second state, the gap between the first and

second pins

200 and 300 is L4, and L3 is equal to or substantially equal to L4. That is, in the third state, the first pin 200 and the second pin 300 are switched to the second state by rotating. In the third state, the gap between the free ends of the first and

second pins

200 and 300 is L2, and L2 is equal to the sum of L1 and L3. If the width of the power adapter 10 is set to L2, the width of the power adapter 10 is greater than L1. It can be understood that, by providing the function that the first pin 200 and the second pin 300 can move relative to the body 100, when the power adapter 10 does not work, the first pin 200 and the second pin 300 can be closed to each other and substantially contact each other, so that the width of the power adapter 10 can be minimized, which is beneficial to reducing the size of the power adapter 10, and is beneficial to lightening and thinning the power adapter 10, and is convenient to use and carry. In addition, when the power adapter 10 does not work, the first pin 200 and the second pin 300 can be respectively attached to the body 100 and do not protrude from the body 100, so that the first pin 200 and the second pin 300 do not stab surrounding objects, and the carrying and storage are convenient.
