Contact type wire-passing hinge with protection circuit

Abstract

The invention belongs to the technical field of intelligent doors, and particularly relates to a contact type wire-passing hinge with a protection circuit. Aiming to solve the problems that a circuitneeds to penetrate into an existing wire-passing hinge, so that short circuit is caused by circuit abrasion when a door is opened and closed for a long time; the contact type wire-passing hinge has poor contact at the moment of contact, and the circuit is easily damaged; and when the wire-passing hinge is abraded and loosened, and the like, the following scheme is provided. The contact type wire-passing hinge with the protection circuit comprises a door frame; an intelligent door is hinged to one side of the door frame; and a first mounting groove is formed in one side of the door frame. According to the contact type wire-passing hinge with the protection circuit, a first touch switch can make good contact with an elastic contact through a fixing assembly when the door is closed, and whenthe door is opened, the circuit is also protected; a first sliding rail releases the contact state prior to the first touch switch, so that instant large current or signal instability caused by poor contact is prevented; and a single-chip microcomputer can recognize which line is in a disconnected state, and an error indication can be sent out in time, so that maintenance and repair are convenient, the structure is simple, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of smart doors, in particular to a contact-type over-wire hinge with a protection circuit. Background technique [0002] Smart door refers to the anti-theft door that realizes many intelligent functions on the basis of the traditional anti-theft safety door through emerging technical means and the concept of the Internet of Things, with the intelligent system host as the carrier.

[0002] Smart door refers to the anti-theft door that realizes many intelligent functions on the basis of the traditional anti-theft safety door through emerging technical means and the concept of the Internet of Things, with the intelligent system host as the carrier. The current market There are many wire passing systems on the Internet, such as wire network, eye level, networked door lock, community access control, unit system, unit intercom, etc., but most power lines are exposed between the door and the door frame through hoses

[0003] Existing thread-through hinges require circuits to penetrate into the hinges. Long-term opening and closing of the door may cause short-circuit due to wear and tear of the lines, and contact-type over-wire hinges may cause damage to the circuit due to poor contact at the moment of contact. If the door panel rotates for a long time, there will be wear and loose phenomena, which will cause damage to the hinge and reduce the service life of the hinge. Therefore, we propose a contact-type over-the-line hinge with a protection circuit to solve the above problems. mentioned problem
