Non-attachment power supply and signal transmission device

Abstract

The invention belongs to the technical field of non-contact power supply and signal transmission, particularly, relates to a non-attachment power supply and signal transmission device. The non-attachment power supply and signal transmission device comprises an emission apparatus and a receiving apparatus. The non-attachment power supply and signal transmission device is characterized in that the emission apparatus is composed of an over-voltage protection circuit, an intermediate-frequency pulse generator, a power conversion circuit and a primary coil iron core, which are connected orderly; the receiving apparatus is formed by connection of a secondary coil iron core and a power restoring circuit, and the primary coil iron core and the secondary coil iron core are not interconnected, and are spaced by a certain gap. The non-attachment power supply and signal transmission device has the advantages of simple structure, convenience in use, steady operation, strong environmental suitability, long service life and the like.

Description

technical field [0001] The invention belongs to the technical field of contactless power supply and signal transmission, in particular to a wireless power supply and signal transmitter. Background technique [0002] In the prior art, power transmission mainly adopts fixed wire transmission or contact power transmission, but in many products, there are situations where signals need to be transmitted between two moving parts, such as a relatively fixed bottom part and a The situation where the upper rotating parts need to transmit signals, such as lighting systems, radar systems and other products. The above-mentioned products all need not only power supply, but also relative movement between parts, and the solution currently adopted is mainly realized through the slip ring structure. The principle of the slip ring structure is to set a contact on a conductive On the ring-shaped or other existing conductors, it can maintain contact during the sliding process, thus achieving t...

Problems solved by technology

The above-mentioned products all need not only power supply, but also relative movement between parts, and the solution currently adopted is mainly realized through the slip ring structure. The principle of the slip ring structure is to set a contact on a conductive On the ring-shaped or other existing conductors, it can maintain contact during the sliding process, thus achieving the function of transmitting electric energy; but the problems with this transmission structure are: first, two objects move with each other to generate friction, making the object very Fast damage and limited service life; second: poor contact is likely to occur between conductors that move with each other, resulting in sparks and large currents that accelerate the damage of objects; third: due to mutual movement, they are not isolated from the air in many cases working under the state, so it is easy to be corroded in the harsh environment
