A Circuit Alternative to Brush Structure in Slip Ring

Abstract

The invention discloses a circuit for replacing an electric brush structure in a slip ring. The circuit comprises a transmitting module and a receiving module. The transmitting module comprises a front-end digital processor, an optical signal transmitter and a wireless power transmitter, wherein the front-end digital processor is provided with three output ends, the first output end is connected with the optical signal transmitter, and the second output end and the third output end are connected with the wireless power transmitter. The receiving module comprises an optical signal receiver, a rear-end digital processor, a wireless power receiver, a DC-DC converter and a power source, wherein the output end of the optical signal receiver is connected with the rear-end digital processor, the output end of the wireless power receiver is connected with the DC-DC converter, and space transmission is adopted between the wireless power transmitter and the wireless power receiver as well as between the optical signal transmitter and the optical signal receiver. The circuit for replacing the electric brush structure in the slip ring has the advantages that the electric brush structure in the traditional slip ring is replaced, the problems that due to the electric brush structure, heat dissipation is difficult, and friction loss is large are avoided, the service life of the slip ring is prolonged, and the reliability of the slip ring is improved.

Description

Technical field [0001] The invention relates to a circuit that replaces the brush structure in a slip ring, in particular to a circuit that uses wireless transmission instead of wired transmission. Background technique [0002] The existing slip ring belongs to the application category of contact sliding connection, also known as slip ring or adapter, which is a precision power transmission device that realizes the data signal and power transmission of two relative rotating mechanisms. The existing slip ring includes a slip ring ring body, multiple input wires, multiple output wires, multiple conductive rings, a brush holder and multiple brushes located in the slip ring ring body. The brush holder is a cantilever beam structure supported by a single end. It has multiple cantilevers. The number of input wires, output wires, conductive rings, brush holder cantilevers and brushes are the same. The brushes are installed on the top of the cantilever of the brush holder. Multiple condu...
