Abstract

The invention discloses a circuit structure of a light curtain wireless connection device. The circuit structure is characterized in that the receiving end of a light curtain is connected with a left electric storage box, and the transmitting end of the light curtain is connected with a right electric storage box; a charging box is arranged between the left electric storage box and the right electric storage box; charging sockets are positioned on the two sides of the charging box, and the left electric storage box and the right electric storage box are provided with charging plugs matched with the charging sockets. The left electric storage box is provided with an infrared emission head, the charging box is provided with a first infrared receiving head, and the right electric storage box is provided with a second infrared receiving head. The light curtain wireless connection device of an elevator door not only can provide power supply box control signals necessary for normal working of the light curtain, but also can improve reliability and prolong the service life of the light curtain.

Description

technical field [0001] The present application relates to the field of elevator doors, in particular to a wireless connection device for an infrared protector of an elevator door (the infrared protector is referred to as a light curtain hereinafter), and in particular to its electrical connection structure. Background technique [0002] At present, the conventional elevator door light curtain is composed of a host, a transmitter and a receiver. The main engine is installed on the top of the elevator door car, the power is input by the main engine, the transmitter and the receiver are installed on the two elevator car doors respectively, and the three must be connected with each other by cables to ensure the power supply and signal transmission. When the elevator door can be opened and closed, when people or objects enter the light curtain protection area, the elevator door will automatically open to prevent people and objects from being run over. During the long-term use of...
