Problems solved by technology

However, in many cases, it is only necessary for the door to be closed intentionally, and frequent unintentional closing of the door, on the one hand, affects the efficiency of the door and causes a lot of inconvenience, on the one hand, it is also easy to generate environmental noise, and at the same time, it is easy to cause damage to the door, reducing the The service life of the door body

Embodiment 1

[0028] Such as image 3 , Figure 4 As shown, the action control mechanism of the baffle plate 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 plate 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 .

[0029] The anti-accidental closing method of the above-mentioned automatic door lock system is:

[0030] 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 ele...

Embodiment 2

[0034]Compared with Embodiment 1, the door closing signal sensing module 3 adopts a pressure sensor, such as Figure 5 Shown, others are with embodiment 1.

[0035] It should be noted that, in this embodiment, the door closing signal sensing module 3 senses a pressure signal, that is, a signal of the magnitude of the force when a person exerts force on the door body 2, rather than the distance between the person and the door body 2 Signal. The door-closing signal sensing module 3 is used to detect the magnitude of the force between the person and the door body 2 and output a corresponding door-closing signal to define human-made door-closing behavior and accidental door-closing caused by non-human factors. When the automatic door lock system judges that the door is closed manually, the electromagnet 8 is energized, so that the lock box 6 is in an open state, and the door is closed; otherwise, when the automatic door lock system judges that the door is closed accidentally, the...

Embodiment 3

[0037] Compared with Embodiment 1, a comparator is added between the amplification filter module and the electromagnet 8, such as Image 6 Shown, others are with embodiment 1.

[0038] Usually, when the distance between the person and the proximity switch reaches a certain distance, for example, 5 cm, the proximity switch 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 someone approaches the proximity switch, the proximity switch senses the door closing signal, that is, the distance signal between the person and the door body 2, and outputs the signal as a voltage signal, and the output voltage U is output to the amplification and filtering module, After being processed by the amplification and filtering module, the output voltage U', the voltage U' signal is first output to the comparator, and in the comparator, U' is compared with the...

Abstract

The invention provides an automatic door lock system and an accident-preventing door closing method. The automatic door lock system comprises a door closing signal sensing module, a first comparator,a second comparator, a logic control module, a door closing signal sensing control module, and after the door closing signal sensing control module detects that a door closing signal output by the second comparator lasts for a certain period of time, the door closing signal is output to the logic control module; the logic control module processes the door closing signals correspondingly output bythe door closing signal sensing control module and the first comparator and forms a specified door closing signal, the specified door closing signal is output to a baffle action control mechanism, andthe baffle action control mechanism controls a baffle to move relative to a latch box until the latch box is in an open state. According to the automatic door lock system, the specified door closingaction intention is converted into the corresponding specified door closing signal according to the respective characteristics of intentional door closing and unintentional door closing, and thus theunexpected closing of the door body is effectively prevented based on the different characteristics of different door closing intentions.

Description

technical field [0001] The invention relates to the technical field of door closing action control, in particular to an automatic door lock system and a method for preventing accidental door closing from unintentional closing when the door body is opened and not fixed. Background technique [0002] Usually, the door body and the door frame are connected by joints such as hinges to form a relatively rotatable movable connection structure. When the door body is opened and not fixed, it is easy to be accidentally closed due to touch or other external forces. [0003] Statistical research has found that when the door is closed accidentally, that is, the door closes unintentionally, it is mainly because the door is subject to external forces such as wind, accidental impact, and slight touch, and the door is closed intentionally, that is, when the door is closed intentionally, usually It is due to the use of limbs or tools to continuously exert force on the door handle on the door...
