Abstract

The utility model provides a magnetically coupled rotating cloud platform. Composed of a fixed body and a rotating body, the feature is that there is a rotary transformer inside the pan-tilt, half of a set of magnetic cores of the rotary transformer is fixed on the fixed body, and the other half is fixed on the rotating body. It uses the working principle of the resolver to realize the brushless and wireless transmission of power supply and signals between the fixed body and the rotating body, reducing the failure rate, so that the rotating body can continue to rotate in one direction without restriction; when it is necessary to transmit multiple signals or power, This can be achieved using a corresponding number of resolvers.

Description

A magnetic coupling transmission rotating platform

technical field

The utility model relates to a rotatable cloud platform, in particular to a platform for transmitting power and signals in a magnetic coupling manner.

Background technique

So far, the power and signal transmission between the fixed body and the rotating body of the rotating pan/tilt has relied on slip rings or direct wires to complete. The former has problems of electromagnetic interference and mechanical wear; the latter has the problem that the pan/tilt cannot continue to rotate in one direction. Defects. After searching the patent database and searching on the Internet, no patent application or article or product for the pan/tilt that realizes the power supply and signal transmission between the fixed body and the rotating body of the rotating pan/tilt by magnetic coupling has not been found. The utility model adopts the magnetic coupling mode to realize the power supply and signal transmission between the fixed body and the rotating body of the rotating platform, and solves the defects in the power supply and signal transmission of the existing platform.

Contents of the invention

The utility model provides a pan platform which uses a rotary transformer group to realize the power supply and signal transmission between the fixed body and the rotating body of the rotating pan platform. Its basic structure is composed of a fixed body and a rotating body. There is a rotary transformer inside the table, and one half of a set of magnetic cores of the rotary transformer is fixed on the fixed body, and the other half is fixed on the rotary body.

The working principle of the utility model is: when the power supply or signal is input into the primary winding of the rotary transformer, through electromagnetic coupling, the secondary winding will output corresponding electric energy or signal, thereby realizing the power supply and signal between the fixed body and the rotating body of the rotary pan/tilt. Brushless and wireless transmission; when multiple signals or power needs to be transmitted, a corresponding number of resolvers can be used to achieve.

The beneficial effect of the utility model is that the failure rate of the platform can be greatly reduced, and the service life of the platform can be prolonged; the rotating body of the platform can continuously rotate in one direction without limitation.
