Problems solved by technology

[0004] When the existing encoder is in use, its rotation stroke is very large, and it needs to rotate 360°, which is inconvenient to use. Because the traditional mechanical encoder uses mechanical contacts, its life is short

Abstract

The invention provides a pressure encoder. The pressure sensor comprises a conductive shell, a rotating shaft with a contact, a pressure sensing module and a circuit board. The contact on the rotatingshaft is arranged opposite to the pressure sensing module, the circuit board is electrically connected with the pressure sensing module, and the conductive shell wraps the rotating shaft, the pressure sensing module and the circuit board. The pressure sensing module is a capacitor formed by two metal plates, one metal plate is grounded, the capacitance change value of the capacitor is detected byextruding the metal plates, then the capacitance change value is converted into a pressure change value, and a corresponding signal is output according to the pressure value. The stroke of the encoder is small, the operation is convenient, and the service life of the product is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a pressure encoder. Background technique [0002] With the rapid development of sensing technology, computer technology and communication technology, the life of equipment is particularly important, and of course the required accuracy is getting higher and higher. [0003] An encoder is a device that compiles and converts signals or data into signal forms that can be used for communication, transmission and storage. The encoder converts angular displacement or linear displacement into an electrical signal, the former is called a code disc, and the latter is called a yardstick. [0004] When the existing encoder is in use, its rotation stroke is very large, and it needs to rotate 360°, which is inconvenient to use. Because the traditional mechanical encoder uses mechanical contacts, its service life is relatively short. Contents of the invention [0005] In view o...
