Embodiment 1

[0031] Such as image 3 , Figure 4 As shown, the motion control mechanism of the baffle 10 mainly includes an electromagnet 8 and a spring 9. One end of the spring 9 is fixed on the door frame 4 or the wall where the door frame 4 is located, and a mechanical mechanism is formed between the other end of the spring 9 and the baffle 10. Connection structure. Such as Figure 5 As shown, the door closing signal sensing module 3 adopts a proximity switch, such as a commonly used infrared proximity switch, and the infrared proximity switch is electrically connected to the electromagnet 8.

[0032] The implementation method for preventing accidental closing of the smart door lock system is:

[0033] When someone approaches the infrared proximity switch, if the distance between the person and the infrared proximity switch is less than or equal to the expected distance calibrated by the infrared proximity switch, for example, 5cm, the infrared proximity switch outputs an electrical signal w...

Embodiment 2

[0037] Compared with Embodiment 1, the door closing signal sensing module 3 uses a pressure sensor, such as Figure 5 As shown, the others are the same as in Example 1.

[0038] It should be noted that in this embodiment, the door-closing signal sensing module 3 is a pressure-sensing signal, that is, a signal of the force when a person applies force to the door 2 instead of the distance between the person and the door 2 signal. The door closing signal sensor module 3 is used to detect the force between the person and the door body 2 and output the corresponding door closing signal to define the door closing behavior caused by human and accidental door closing caused by non-human factors. When the smart door lock system judges that the door is closed manually, the electromagnet 8 can be energized, so that the lock box 6 is in an open state, and the door is closed; on the contrary, when the smart door lock system judges that the door is closed accidentally, the electromagnet 8 is n...

Embodiment 3

[0040] Compared with embodiment 1, a comparator is added between the amplifying filter module and the electromagnet 8, such as Image 6 As shown, the others are the same as in Example 1.

[0041] Generally, when the distance between a person and the proximity switch reaches a certain distance, for example, when the distance is 5 cm, the proximity switch correspondingly outputs a certain voltage. After the certain voltage is calibrated, the corresponding proximity distance is the expected distance calibrated by the proximity switch. In this embodiment, when a person approaches the proximity switch, the proximity switch outputs the sensed door closing signal, that is, the distance signal between the person and the door 2 as a voltage signal, and the output voltage U is output to the amplifying and filtering module, After being processed by the amplifying and filtering module, the voltage U'is output. The voltage U'signal is first output to the comparator. In the comparator, U'is com...

Abstract

The invention provides an intelligent door lock system and an implementation method of preventing a door from being closed accidentally. The intelligent door lock system comprises a box striking plate, a baffle, a baffle motion control mechanism and a door-closing signal induction module, wherein a door-closing signal sensed by the door-closing signal induction module is output to the baffle motion control mechanism; when the specified door-closing signal input exists in the baffle motion control mechanism, the baffle is controlled to move relative to the box striking plate by the baffle motion control mechanism till the box striking plate is opened; when the baffle motion control mechanism has no specified door-closing signal input, the baffle is controlled to move opposite to the box striking plate by the baffle motion control mechanism till the box striking plate is closed. In the invention, according to the features of closing the door on purpose and closing the door accidentally, the specified door-closing behavior intensions are converted into the corresponding specified door-closing signals so that the door is effectively prevented from being closed accidentally based on different features of different door-closing intentions.

Description

Technical field [0001] The present invention relates to the technical field of door closing action control, and in particular to an intelligent door lock system that prevents unintentional closing of a door body in an open and unfixed state and an implementation method for preventing accidental door closing. Background technique [0002] Generally, a movable connection structure is formed between the door body and the door frame through hinges and other connecting pieces. When the door body is opened and not fixed, it is easy to accidentally close due to touch or other external forces. [0003] Statistical studies have found that when the door is accidentally closed, the door closes unintentionally, mainly because the door is subjected to external forces such as wind, accidental impact, and light touch. The intentional closing behavior, that is, when the door is intentionally closed, usually It is because of using limbs or tools to continuously exert force on the door handle on the...
