Detailed Description

The present invention will be further described with reference to the following drawings and examples, which should be understood as illustrative and not restrictive.

The separable power supply connection mechanism, as shown in fig. 1, includes an upper component 10 connected to a functional module circuit (not shown) and a lower component 20 connected to a seat power supply, wherein the upper component 10 and the lower component 20 are kept in contact when in use, and are kept separated when not in use.

As shown in fig. 2, the upper member 10 includes an upper member bottom cover 11, a first conductive copper ring 12, and a magnet 13. The upper part bottom cover 11 is fixed with the first conductive copper ring 12 through a buckle, and the magnet 13 is accommodated in the first conductive copper ring 12 and fixed on the upper part bottom cover 11 through double faced adhesive tape, glue, clamping or insert injection molding. The negative pole of the functional module circuit (not shown) is welded to the first conductive copper ring 12, and the positive pole is welded to the magnet 13. According to different requirements of users, different functional module circuits can be selected, such as a wireless charging module circuit, an electronic screen module circuit and the like. The magnet 13 is made of a conductive metal material, and a material having a better conductivity, for example, a copper sheet, may be attached to the surface thereof.

As shown in fig. 3, the lower member 20 includes a lower member top cover 21, a second conductive copper ring 22, a third conductive copper ring 23, and an iron block 24. A second conductive copper ring 22 is fixed to one side of the lower-part top cover 21 by snap-fitting, and a third conductive copper ring 23 is snap-fitted to the other side of the lower-part top cover 21. The iron block 24 is fixed to the lower member top cover 21 by snap-fitting through the third conductive copper ring 23. The negative pole of the seat power supply (not shown) is welded to the second conductive copper ring 22 and the positive pole is welded to the third conductive copper ring 23.

The iron block 24 is a cylindrical boss structure and is a movable connecting conductor, as shown in fig. 4, and includes an iron block main body 25 and two symmetrical sound-deadening blocks 26. The sound damping mass 26 may be a compressible, flexible material such as PUR, TPU, TPV, or the like.

The upper part bottom cover 11 and the lower part top cover 21 are made of insulating plastic.

In use, the upper member 10 is placed directly on the lower member 20, and both members are brought into contact by magnetic force to energize the upper member 10. At the end of use, the upper part 10 is removed and the two parts are separated against the action of the magnetic force. The operation is simple, and the appearance of the whole seat is not affected.

When the upper and lower parts are separated, both parts are in an independent state. When the lower part is in an independent state, as shown in fig. 5, the top cover 21 of the lower part is used as an insulating material to block the positive power supply carried by the second conductive copper ring 22, and the iron block 24 is separated from the third conductive copper ring 23 due to the self-gravity. Therefore, in the state, no forward current exists in the exposed area, short circuit of the lower component cannot be caused, and the user does not have electric shock risk.

When the upper and lower parts are in contact, the mechanism is in an operative state. As shown in fig. 6, the magnet 13 magnetically attracts the iron block 24, so that the iron block 24 moves upward by a distance (e.g., 2mm) to be in contact with the magnet 13 and the third conductive copper ring 23. The iron block 24 serves as a conductor to transmit the forward power of the seat on the third conductive copper ring to the magnet 13, thereby energizing the upper member 10.

If water drops inadvertently enter the mechanism, the upper part bottom cover 11 and the lower part top cover 21 will naturally separate the water, separating the positive and negative poles of the overall circuit and placing them in different water zones, so that the circuit will not fail due to short circuit.

If the conductor falls into the mechanism carelessly, a gap exists between the magnet 13 and the iron block 24, so that the iron block 24 cannot be in contact with the anode of the whole chair, the power supply connection mechanism is in an open circuit state, short circuit cannot be caused, and system safety is guaranteed.

First electrically conductive copper ring 12, second electrically conductive copper ring 22 and third electrically conductive copper ring 23 also can adopt other good metal material of electric conductive property as required.

What has been described above is only the preferred embodiment of the present invention, not for limiting the scope of the present invention, but various changes can be made to the above-mentioned embodiment of the present invention. All the simple and equivalent changes and modifications made according to the claims and the content of the specification of the present invention fall within the scope of the claims of the present invention. The present invention is not described in detail in the conventional technical content.
