Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

Furthermore, the terms "long", "short", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships illustrated in the drawings, and are only for convenience of describing the present invention, but do not indicate or imply that the device or element referred to must have the specific orientation, operate in the specific orientation configuration, and thus, should not be construed as limiting the present invention.

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

Referring to fig. 1 to 3, the present embodiment provides a concealed charger, which includes an insulating housing 1, a metal contact 2, a torsion spring, a fastening assembly 4 and a circuit board 5.

The insulating shell 1 comprises a first side surface 101, a middle frame 102 and a second side surface 103, wherein the middle frame 102 is positioned between the first side surface 101 and the second side surface 103. The circuit board 5 is electrically connected with the metal contact 2 and is located in a space enclosed by the first side surface 101, the middle frame 102 and the second side surface 103. The outer surface of the middle frame 102 is provided with an anti-slip boss 1021 so as to avoid slipping and facilitate plugging and unplugging. The contact receiving groove 1022 and the key receiving groove are formed on the same side of the middle frame 102. Optionally, the hidden charger provided in this embodiment has two metal contacts 2 (one zero one fire), so the number of the contact receiving grooves 1022 is also two, and each contact receiving groove 1022 is used for receiving one metal contact 2.

One end of the metal contact 2 is rotatably connected to one end of the contact accommodating groove 1022 around the contact rotating shaft 3, and the other end thereof is rotatably accommodated in the contact accommodating groove 1022. The torsion spring is sleeved on the contact piece rotating shaft 3, one torsion arm is fixedly connected with the insulating shell 1, and the other torsion arm is fixedly connected with the metal contact piece. In a natural state, the torsion spring drives the other end of the metal contact piece 2 to rotate in a direction away from the contact piece accommodating groove 1022, so that the function of automatically popping up the metal contact piece 2 is realized.

The latch assembly 4 includes a bottom case 401, a compression spring, a locking portion 402 located in the contact receiving groove 1022, and a key portion 403 located in the key receiving groove.

The locking part 402 is fixedly connected with the key part 403; the bottom case 401 is fixed inside the insulating housing 1 and is located on one side of the key part 403 away from the key accommodating groove; the compression spring is located between the bottom case 401 and the key portion 403, initially, the key portion 403 is located at a first limit position protruding from the surface of the middle frame 102, when the key portion 403 is pressed downward by a hand, the key portion 403 is depressed to be flush with the surface of the middle frame 102 and presses the compression spring, which is a second limit position, and after the hand is released, the compression spring drives the key portion 403 to move from the second limit position to the first limit position.

It can be understood that, when the key part 403 is located at the first limit position, the locking part 402 is located above the metal contact piece 2, so that the other end of the metal contact piece 2 is locked in the contact piece accommodating groove 1022, when the key part 403 is pressed down to the second limit position, the key part 403 moves down, the locking part 402 also moves down because the locking part 402 is fixedly connected with the key part 403, and because the locking part 402 has good deformation capability, the locking part 402 is flexibly deformed in a direction away from the metal contact piece 2, and finally the locking part 402 slides down to the side surface of the metal contact piece 2, so as to release the locking of the metal contact piece 2; then, the torsion spring drives the other end of the metal contact 2 to automatically pop up, and rotates in a direction away from the contact accommodating groove 1022.

In short, pressing the key part 403 inward releases the latch part 402 from the metal contact 2, and the torsion spring causes the metal contact 2 to automatically pop out. It can be understood that, the angle of the metal contact piece 2 automatically popping out can be adjusted by adjusting the angle of the first torsion arm and the second torsion arm in the natural state.

Optionally, the key receiving groove is located at an end of the contact receiving groove 1022 far from the contact rotating shaft 3, so that the locking portion 402 locks an end of the metal contact 2 far from the contact rotating shaft 3.

Referring to fig. 4, in this embodiment, the end surface of the metal contact piece 2 close to the locking portion 402 is an arc surface with a middle portion protruding toward the locking portion 402, so that the locking portion 402 slides from the top of the metal contact piece 2 to the side surface of the metal contact piece 2.

According to the hidden charger provided by the embodiment, when the key part 403 is pressed down to charge, the metal contact piece 2 is automatically popped out, and then the metal contact piece 2 can be inserted into the jack; when not needing to charge, order about metal contact 2 with the hand and rotate to get into contact storage groove 1022 in, collude lock portion 402 can carry out the locking with metal contact 2 automatically, and metal contact 2 no longer exposes, neither occupies the space, is convenient for accomodate again, has regular pleasing to the eye advantage.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
