DETAILED DESCRIPTION

[0022] As shown in the accompanying drawings, this embodiment provides a communication charging slip ring, which includes a shaft component located in the middle and a rotating component that can rotate externally relative to the shaft component.

[0023] The shaft components include a communication copper ring part 1 at the bottom, a grounding copper ring part 2 in the middle and a power supply copper ring part 3 at the top. The communication copper ring part 1, the grounding copper ring part 2 and the power supply copper ring part 3 are separated by partition plates 4 respectively.

[0024] The communication copper ring portion 1 includes multiple stacked communication copper rings 24, designed to carry a rated current of 20A while also meeting light-load charging requirements. A communication separator 25 is placed between adjacent communication copper rings 24. The optimal number of communication copper rings 24 is 12. Since the theoretical maximum number of communication cores is 12, this design can meet over 95% of market requirements.

[0025] The power supply copper ring portion 3 includes two power supply copper rings 36 distributed above and below. The two power supply copper rings 36 are respectively connected to a terminal block 10. The two power supply copper rings 36 are used to pass the power supply current. A partition plate 4 is also provided between the two power supply copper rings 36. The grounding copper ring portion 2 is provided with a grounding copper ring 37 for grounding.

[0026] A lower partition 5 and a lower base 6 are arranged in sequence below the communication copper ring part 1, and an upper partition 7 and an upper base 8 are arranged in sequence above the power supply copper ring part 3. The upper base 8, the upper partition 7, the power supply copper ring part 3, the grounding copper ring part 2, the communication copper ring part 1 and the partitions 4 of each part are connected together by multiple central screws 9 and nuts.

[0027] Wiring lugs 10 are respectively led out from the two power supply copper rings 36 of the power supply copper ring part 3 and the grounding copper ring 37 of the grounding copper ring part 2. By leading the power supply copper ring 36 and the grounding copper ring 37 to the outside of the slip ring through the wiring lugs 10, wiring installation is facilitated.

[0028] The rotating parts include an upper support plate 11, an intermediate support plate 12, and a lower support plate 13. An insulating plate 14 is provided closely below the upper support plate 11. The insulating plate 14 is used to insulate the uppermost brush copper ring and other mechanisms from the support plate and increase the electrical clearance and creepage distance.

[0029] A plurality of upper fixing posts 15 are provided between the insulating plate 14 and the intermediate support plate 12. The power supply copper ring 3 and the grounding copper ring 2 are located between the insulating plate 14 and the intermediate support plate 12. Grounding brushes 16 and power supply brushes 17 are provided on the upper fixing posts 15 to match the grounding copper ring 2 and the power supply copper ring 3, respectively. Each of the two power supply copper rings 36 corresponds to a power supply brush 17.

The double-eared brush holder 30 is mounted on the upper fixed column 15 via earrings at both ends. The large brush 31 is located in a slot in the middle of the double-eared brush holder 30. The brush copper plate 34 is located above the large brush 31 and connected to the double-eared brush holder 30. The threaded terminal block 35 is located to the side of the double-eared brush holder 30 and connected to the brush copper plate 34, serving as a terminal block and cover. The two ends of the large compression spring 32 contact the large brush 31 and the threaded terminal block 35, respectively. The brush spring 33 is located below the large brush 31 and presses the large brush 31 against the brush copper plate 34.

[0031] A metal lining plate 18 is provided closely below the middle support plate 12. The metal lining plate 18 serves as a metal shielding layer and is grounded to the external shell through bolts. The influence of high-frequency charging will be blocked by the metal lining plate 18, thereby ensuring that the microcurrent of the signal line will not be disturbed.

[0032] Multiple lower fixing posts 19 corresponding to upper fixing posts 15 are positioned between the metal backing plate 18 and the lower support plate 13. The communication copper ring 1 is positioned between the metal backing plate 18 and the lower metal plate. Two communication brushes 20 are provided, which mate with the communication copper ring 24 and are connected to both the metal backing plate 18 and the lower support plate 13.

[0033] The communication brush 20 includes a multi-slot brush holder 26, multiple small brushes 27, small compression springs 28 corresponding to the small brushes 27, and a brush pressure plate 29. The multi-slot brush holder 26 is connected to the metal lining 18 and the lower support plate 13. Each small brush 27 is respectively located in each slot of the multi-slot brush holder 26 and an electronic wire is welded at the tail. Each small compression spring 28 passes through each electronic wire and presses each small brush 27 respectively. After the brush pressure plate 29 presses the small compression spring 28, it is connected and fixed to the multi-slot brush holder 26.

[0034] An outer edge screw 21 passes through the corresponding upper fixing column 15 and lower fixing column 19 at the same time. The outer edge screw 21 passes through the upper support plate 11, the insulating plate 14, the middle support plate 12, the metal lining plate 18 and the lower support plate 13 at the same time and is fixed by a nut.

[0035] The upper support plate 11 and the upper base 8 are connected by an upper bearing 22, and the lower support plate 13 and the lower base 6 are connected by a lower bearing 23, so that the rotating parts and the shaft parts can rotate relative to each other. Through the rotation of the rotating parts, the brushes and the copper rings move relative to each other to achieve work.

[0036] It can be understood that the above specific description of the present invention is only used to illustrate the present invention and is not limited to the technical solutions described in the implementation methods of the present invention. Ordinary technicians in this field should understand that the present invention can still be modified or replaced by equivalents to achieve the same technical effects; as long as the use requirements are met, they are within the scope of protection of the present invention.
