Rotating angle sensor

Abstract

The invention discloses a rotation angle sensor which is characterized in that: the rotation angle sensor comprises a moving sleeve which is sleeved with a rotating shaft and a box body which is connected with the moving sleeve, a thread ring is arranged at the upper part of the moving sleeve, a locking mechanism which is matched with the rotating shaft by pressing is arranged inside the thread ring, a fixed ring is screwed at the periphery of the thread ring, the moving sleeve, the thread ring and the fixed ring are concentric and coaxial split-type round ring structures which are assembled by more than two arc-shaped components; teeth are distributed on the circumferential direction of the outer edge of the moving sleeve, a speed reduction device which is meshed with the teeth and mainly composed of multi-level gear groups is arranged in the box body, the speed reduction device is fixed on a circuit board component, and a sensing component is connectedly fixed at the periphery thereof. The rotation angle sensor can realize the flexible dismantlement-free installation and obtain the position sensing with any angle, the structure is simple and the cost is low, thereby having great popularization value.

Description

technical field [0001] The invention relates to the technical field of angle measuring instruments, in particular to a sensor for detecting rotation angles. Background technique [0002] At present, whether it is a locomotive, electromechanical equipment, or an automobile, a ship, or even an airplane, sensors that detect the speed and angle of rotation of its shaft-type rotating mechanism are applied. There are various types of such sensors, which can be inductive type, resistive, capacitive, photoelectric or other forms of sensors. For example, the Chinese patent number is 200720063163.X, the application date is May 5, 2007, and the name of the invention is an automobile steering wheel steering angle display device, which is characterized in that an angle sensor is installed on the steering mechanism of the automobile, and the angle sensor and signal processing The circuit is connected, and the signal processing circuit is connected with the display circuit. This patent c...

Problems solved by technology

This patent can display the turning angle of the car from the display circuit, which can improve the accuracy of controlling the driving direction of the car and improve driving safety, but the installation of the angle sensor is inconvenient. Generally, the machine must be disassembled to install it, and maintenance is very inconvenient. ; Moreover, it is generally difficult to accurately detect the rotation angle and speed of the rotating shaft type rotating mechanism directly through the sensor, and its stability is not high
