Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
As shown in fig. 1, the utility model discloses an anti-interference door lock, which comprises a lock body, a touch PCB board 2 and a main control board, wherein the touch PCB board 2 is connected with the main control board to control the switch of the lock body; the touch PCB 2 is provided with a front side, the front side is arranged to face the outer side of the door when the anti-interference door lock is installed and fixed on the door, and the touch PCB 2 is also provided with a back side which faces the inner side of the door and is opposite to the front side when the anti-interference door lock is installed and fixed on the door; the touch PCB 2 is provided with a touch key 1 positioned on the front surface and a card swiping antenna 3 positioned on the back surface.
Through arranging the card swiping antenna 3 and the touch keys 1 on the back and the front of the touch PCB board 2, a certain distance exists between the card swiping antenna 3 and the touch keys 1, the mutual interference between the card swiping antenna 3 and the touch keys 1 on the touch PCB board 2 is reduced, the noise immunity of the card swiping antenna 3 to an external interference source is improved, meanwhile, the influence of a card swiping signal on the touch keys 1 is reduced, and the safety and reliability of the intelligent lock are improved.
The touch PCB board 2 is connected with the main control board, and a user can input a preset password through the touch key 1 or use a chip to control the lock body to be opened through a card swiping signal by the main control board. The lock body can adopt the structure disclosed in the Chinese patent with the publication numbers CN207485114U and CN207436686U, and also can adopt other existing mature schemes, which are not described in detail in the utility model.
The touch key 1 is arranged on the front surface of the touch PCB 2, and a user can input an unlocking password through the touch key 1. The card-swiping antenna 3 can be arranged in an area outside the horizontal plane of the touch key 1, such as the area of the back surface. In this embodiment, the card swiping antenna 3 is disposed on the back surface of the touch PCB 2, so that the touch PCB 2 is disposed between the card swiping antenna 3 and the touch key 1, and mutual interference signals between the two are reduced. Meanwhile, the card swiping antenna 3 and the outside have an extra PCB, so that the immunity of the card swiping antenna 3 to external interference sources such as electrostatic interference, interphone interference, Tesla coil interference, electric impact drill interference and the like is enhanced, the identification efficiency of the card swiping antenna 3 to a chip is improved, and the use safety of the anti-interference door lock is enhanced.
