Antenna device of electronic lock with metal frame
The invention discloses an antenna device of an electronic lock with a metal frame, comprising a lock main body, an indoor housing for cooperating with the lock main body to install on the inner side of the door, a metal frame which is designed by integrating with the inner housing, and a feeding point and a ground-feeding point which are arranged on the inner side of the metal frame. A radio frequency front end transmit-receive circuit is positioned on a PCB board which is arranged in the lock main body; two connectors which are a first connector and a second connector are arranged on two sides of the lock main body; at least one notch is formed on the bottom edge of the metal frame and is used as a signal radiation channel; and metal becomes part of the antenna through the notch in the metal frame, and the feeding point is connected to the radio frequency front end transmit-receive circuit through the second connector. The antenna device of the electronic lock with the metal frame solves the problem that the metal severely affects the wireless signal of the electronic lock. The metal becomes part of the antenna through the notch on the metal frame, which can solve the problem that the wireless signal is weak.
