Description

Technical Field

[0001] The present application relates to the field of controller technology, and in particular to a magnetic induction controller. Background Art

[0002] The controller can convert mechanical signals into electrical signals and output them.

[0003] In the related technology, the conversion of signals relies on the conversion of mechanical structures, that is, the controllers currently on the market rely on contacts and contact pieces to perform signal conversion. The contacts contact contact pieces at different positions, generate signals after contact and transmit the signals through the circuit board.

[0004] In the process of implementing the above, the inventors found that there are at least the following problems in this technology. The model transmission method in the prior art relies on a mechanical structure, and contact will occur between the contact point and the contact piece. Therefore, poor contact may occur, resulting in unstable signal transmission and poor stability. Summary of the invention

[0005] In order to improve the stability of signal transmission, the present application provides a magnetic induction controller.

[0006] The magnetic induction controller provided in this application adopts the following technical solution:

[0008] By adopting the above technical solution, the signal output part and the signal receiving part transmit signals through electromagnetic induction. During the signal transmission process, the signal output part and the signal receiving part will not come into contact, so there will be no signal transmission interruption or unstable signal transmission due to poor contact. At the same time, the electromagnetic induction transmission can record the signal strength of the signal source and the signal receiving part in real time, so as to judge the position change of the signal source, increase the sensitivity of signal transmission, and is suitable for scenarios with high sensitivity requirements.

The transmission disk is placed between the two obstruction parts, and the diameter of the transmission disk is larger than the diameter of the inner wall of the transmission part.

[0016] By adopting the above technical solution, the diameter of the transmission disk is larger than the diameter of the inner wall of the transmission part, so that the transmission disk will not separate from the transmission part during movement. At the same time, the transmission disk is placed between the two obstruction parts, so that the shaking amplitude of the transmission disk along the axial direction during movement is reduced, thereby improving the stability of the movement of the fixed part.

[0017] Optionally, an annular spring is provided between the upper plate and the lower plate, and the annular spring abuts against a side wall of the transmission disc.

[0018] By adopting the above technical solution, the annular spring abuts against the side wall of the transmission disc. When the transmission disc moves, the annular spring is driven to move. The annular spring provides elastic force to the transmission disc, so that the transmission disc can be reset after movement.

[0019] Optionally, a rotation recording device is fixed inside the installation body, and the signal output part drives the rotation recording device to rotate.

[0020] By adopting the above technical solution, the rotation recording device is used to record the rotation of the signal output part and convert it into an electrical signal for output.

[0022] By adopting the above technical solution, the signal output part drives the third transmission member to rotate, and the third transmission member drives the second transmission member to rotate, thereby driving the rotating recording device to rotate. At the same time, the third transmission member can slide on the second transmission member without interfering with the movement of the signal output part.

[0023] Optionally, a third transmission groove is formed on the third transmission member, and the signal output part further includes a fourth transmission member, which is inserted into the third transmission groove. The signal output part rotates to drive the fourth transmission member to rotate.

[0024] By adopting the above technical solution, the signal output part drives the fourth transmission member to rotate, and at the same time the fourth transmission member can move in the third transmission groove, and its movement direction is perpendicular to the movement direction of the third transmission member, which will not interfere with the movement of the signal output part.

[0025] Optionally, the cross section of the fourth transmission member includes at least one plane portion flush with and abutting against the inner side wall of the third transmission groove; and includes at least one abutting portion abutting against the side wall of the third transmission groove away from the plane portion.

[0026] By adopting the above technical solution, one side of the fourth transmission member is in contact with the inner wall of the third transmission groove, so that the fourth transmission member can push the inner wall of the third transmission groove to move during rotation, thereby driving the third transmission member to move.

[0046] Reference Figure 1 The side wall of the installation body 1 is also provided with a plurality of control buttons, each of which can output different signals, which are converted into electrical signals through the circuit board for output.

[0047] The implementation principle of a magnetic induction controller in an embodiment of the present application is: control the signal output part 3 to move or rotate. After the position of the signal output part 3 changes, the position signal is transmitted to the signal receiving part 2.
