Induction type automobile door step lamp and anti-pinch device switch based on Hall element

Abstract

The invention discloses an induction type automobile door step lamp and anti-pinch device switch based on a Hall element. The induction type automobile door step lamp and anti-pinch device switch comprises a Hall component, a signal amplifier and a wiring harness. The Hall component comprises the Hall element and a magnet. The Hall element and the magnet are mounted at corresponding positions of a door edge and a door frame correspondingly. The output of the Hall element is connected with the signal amplifier through the wiring harness. The output of the signal amplifier is connected to a finished automobile electric system through the wiring harness. The finished automobile electric system is connected to control the work states of an automobile door step lamp and an anti-pinch device. According to the induction type automobile door step lamp and anti-pinch device switch, the Hall element and the magnet are mounted at the corresponding positions of the door edge and the door frame correspondingly; in the door opening process, the Hall element moves far away from the magnet, in the door closing process, the Hall element moves close to the magnet, and variation of induction signals is generated, so that switch signals of the switch are precise and do not need to be adjusted; the situation that safety is affected due to malfunction of door caused by signal error can be effectively prevented; and meanwhile, work difficulty of site workers is lowered, and production efficiency is improved.

Description

technical field [0001] The invention relates to an inductive door step lamp and an anti-pinch device switch based on a Hall element. Background technique [0002] At present, the door step light switch and anti-pinch switch of general passenger cars are all mechanical switches installed on the door pump shaft. The switch is turned on or off depending on the specific position of the cam on the door shaft. And other factors, resulting in signal distortion amplification, can not correctly indicate the state of the door, and even can not meet the requirements of relevant regulations. Contents of the invention [0003] The purpose of the present invention is to provide an inductive door step light and an anti-pinch device switch based on a Hall element, which can more accurately transmit the door state signal, prevent the occurrence of safety accidents caused by signal errors, and avoid the difficulty of adjusting the switch by on-site personnel. Increase productivity. [000...
