Problems solved by technology

[0002] The detection of the rotation angle of the camera of the existing smart terminal is usually detected by the Hall sensor, but the data detected by the Hall sensor is a sine wave, so the Hall sensor can only detect the rotation angle of 0 to 180 degrees , when it exceeds 180 degrees, the detected data will be repeated with the previous detection data

Abstract

The invention discloses a rotation angle detection device comprising: a housing, the housing includes a first accommodation groove and a second accommodation groove; a resistance disc is arranged in the first accommodation groove and fixed on the On the side wall; the rotating device, the rotating device is arranged in the second accommodating groove, and can rotate in the second accommodating groove, the rotating device is provided with a toggle lever, when the rotating device rotates in the second accommodating groove, The toggling rod is rotated in the second accommodating groove to change the resistance between the toggling rod and the resistance disc, thereby detecting the rotation angle.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a rotation angle detection device. Background technique [0002] The detection of the rotation angle of the camera of the existing smart terminal is usually detected by the Hall sensor, but the data detected by the Hall sensor is a sine wave, so the Hall sensor can only detect the rotation angle of 0 to 180 degrees , when it exceeds 180 degrees, the detected data will be repeated with the previous detection data. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a rotation angle detection device, which can detect the camera from 0° to 360°. [0004] In the first aspect, the embodiment of the present invention provides a rotation angle detection device, comprising: a housing, the housing includes a first accommodation groove and a second accommodation groove; a resistance disk is arranged in the fir...
