The intelligent door lock is characterized in that an unlocking function is set on a front panel of the intelligent lock panel and corresponds to emission control set on a rear panel, an unlocking instruction is sent out when the door is opened, after the unlocking instruction is received by the power adapter, the power adapter outputs power to the magnetic attraction, at the moment, a switch in the magnetic attraction is in an off state, and the magnetic attraction is attracted to a handle of the rear panel, so that a door cannot swing; when the door is closed, an unlocking signal is sent to a remote control receiver in a power adapter for providing power, at the moment, the power output of the power adapter is disconnected, and a door lock and a magnet can be separated to achieve the aim of closing the door.

The emission control board that sets up at the back of intelligent lock is connected with the unlocking function area module electric connection that the front panel set up.

The power adapter is provided with a power remote control receiving controller.

The magnetic attraction setting switch is used for controlling the door opening or closing through magnetic attraction.

Advantageous effects

The intelligent door lock capable of preventing fingers from being pinched when the door is closed solves the potential safety hazard problem that the full-automatic intelligent lock is used for preventing fingers from being pinched when the door is closed in schools, families and offices. Especially students in schools and kindergartens, when the door is closed, the door closer is not noticed, or the hands of the door closer cannot be withdrawn, the hands of the door closer are easily damaged by the door frame, and due to the potential safety hazards, the utility model overcomes the technical problem in the aspects of research and innovation, and the problem of finger damage during the door closing is eliminated by combining technical research with product application.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

The intelligent door lock for preventing fingers from being pinched when the door is closed as shown in fig. 1 to 5 comprises a lock body 1, a power adapter 4 and a magnetic attraction 5 which are connected by an intelligent lock panel, wherein an unlocking function area module 23 is arranged on a front panel 2 of the intelligent lock panel and corresponds to an emission control 35 arranged on a rear panel 3, an unlocking command is sent out when the door is opened, after the unlocking command is received by the power adapter 4, the power adapter 4 outputs power to the magnetic attraction 5, a switch 53 in the magnetic attraction 5 is in an off state, and the magnetic attraction 5 attracts a handle 32 of the rear panel 3, so that the door cannot swing; when the door is closed, an unlocking signal is sent to a remote control receiver 45 in a power adapter 4 for providing power, at the moment, the power output of the power adapter 4 is disconnected, and a door lock and a magnet can be separated, so that the aim of closing the door is fulfilled.
