Swinging driving device taking magnet and hall sensor as detection elements

Abstract

The invention discloses a swinging driving device taking a magnet and a hall sensor as detection elements. The magnet is fixed on a swinging arm of the swinging device such as a swing, the Hall sensor is fixed on a driving motor case of the swing, and a surface of the Hall sensor is close to a surface of the magnet; when the swing swings, the Hall sensor is close to different positions of the surface of the magnet when the swing swings to different angles, different voltages are induced by the Hall sensor, and the voltages represent the positions of the swing. A swinging direction and a swinging peak point of the swing can be calculated by utilizing the absolute position of the swing, an output voltage or a push period of a driving motor can be adjusted by a driving controller of the swing according to the swinging direction or the swinging peak point, and flexible swinging adjustment of the swing can be realized to adapt to use requirements of different users.

Description

Technical field [0001] The invention relates to an electric swing device, a swing drive device using magnets and Hall sensors as detection elements. Background technique [0002] Existing driver solutions for electric swings, cradles, cradles and rocking chairs (hereinafter referred to as swings) can only detect the approximate position of the swing, or detect the relative position of the speed and swing of the swing, or detect the swing of the swing Neither direction nor detection of the swing of the swing can accurately detect the absolute position of the swing. Summary of the invention [0003] In order to solve the above technical problems, the technical problem to be solved by the present invention is to provide a swing driving device that uses a magnet and a Hall sensor as detection elements. [0004] The technical scheme adopted by the present invention is: [0005] A swing drive device using magnets and Hall sensors as detection elements, applied to an electric swing device,...
