Embodiment Construction

[0025] The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0026] like Figure 7 As shown, when the user approaches the door lock and intends to find the lock cylinder 8 and open the door, the photosensitive control part in the HC-SR501 infrared sensor module 4 can determine whether the lighting system works according to whether the light is dim: during the daytime or when the light is relatively bright, the lighting system Does not work; when the light is dim and the user cannot see the keyhole clearly, the HC-SR501 infrared sensor module 4 senses that the human body is within a certain range near the door lock, outputs a high level, and controls the LED to turn on. At this time, the user can easily find the lock cylinder 8 and insert the key 10 into the lock cylinder 8 when the light is bright or the light is dim but the LED is on. When th...

Abstract

The invention provides a door lock device with an alarming function and an illuminating function. The door lock device comprises a door lock, a buzzing device, a mechanical triggering switch device and an illuminating system; the mechanical triggering switch device is installed in a groove of a metal sheet in the door lock, and is connected with a power supply device and buzzers to form a closed loop; when a key is inserted into a lock cylinder to be in contact with a key contact point of the mechanical triggering switch device, a circuit is closed and a time delay module VCC in the power supply device is started, if the key is not pulled out within the set time of the time delay module VCC, the buzzers are started, and then the alarming function is completed; the illuminating system comprises an infrared sensing module, a photosensitive control part in the infrared sensing module determines whether the illuminating system works or not according to whether the light is dim or not, andthe infrared sensing module controls an LED to be lighted when sensing that a human body is located nearby the door lock within a certain range. The door lock device is simple and reasonable in structure, relatively low in cost, safe and reliable, and has good convenience, practicability and economic benefits.

Description

technical field [0001] The invention belongs to the field of anti-theft door locks, and in particular relates to a door lock device with alarm function and lighting function. Background technique [0002] With the rapid development of today's world, various anti-theft door locks emerge in an endless stream, such as Bluetooth locks, face recognition door locks and so on. However, due to reasons such as high cost and difficult installation, various high-end door locks have not been popularized.
