Intelligent power supply induction closing circuit for electric sliding rail of drawer

Abstract

The invention discloses an intelligent power supply induction closing circuit for an electric sliding rail of a drawer. The intelligent induction closing circuit is composed of electronic components including a trigger chip U1, a normally-closed switch S, a triode VT1, a triode VT2 and the like. According to the intelligent power supply induction closing circuit for the electric drawer sliding rail, a battery can be automatically switched from a main storage battery to an auxiliary storage battery for power supply when the main storage battery cannot supply power, normal operation of the operation is guaranteed, the use intelligence of the electric sliding rail is greatly improved, therefore, the electric sliding rail can judge whether the drawer needs to be closed or not according to induction to the surrounding environment, and the defect that the intelligence of an existing electric sliding rail is low is well overcome.

Description

technical field [0001] The invention relates to an intelligent induction closing circuit, in particular to an intelligent power supply induction closing circuit for slide rails of electric drawers. Background technique [0002] A box for storing things in furniture such as drawers, tables, and cabinets. It has a bottom and no cover, and can be pulled out and pushed in. Drawers can be seen everywhere in life, and they are also one of the most frequently used things. [0003] In actual use, people often forget to close the drawer after using it for various reasons, and the open drawer can easily affect people's actions, and even people can easily bump into the open drawer when they are not paying attention, which is not conducive to Protect people's health. [0004] In order to reduce the impact on others due to the user forgetting to close the drawer, many manufacturers will install electric slide rails at the bottom of the drawer. impact. [0005] However, in the process...
