[0032] like Figure 1 and Figure 2 As shown, the door lock state detection device in this embodiment is installed on the door lock, and is specifically fastened to the door lock through the mounting hole 10. The door lock includes a lock body 1, a lock tongue 2 arranged on the lock body 1, and a lock body fastener 3 matched with the lock tongue 2. The door lock state detection device includes: a mounting bracket 4, which is mounted on the lock body 1; a lock tongue sensor, which is arranged on the lock tongue 2 and moves with the movement of the lock tongue 2; and a fastener sensor, which is arranged on the lock body fastener 3; wherein the mounting bracket 4 has a first detection portion 41 corresponding to the position of the lock tongue sensor, and a second detection portion 42 corresponding to the position of the fastener sensor when the door body is closed, the door lock state detection device is provided with a first detection switch in the first detection portion 41, and the first detection switch is triggered by the lock tongue sensor and outputs a first detection signal when the lock tongue 2 is extended or retracted, and the door lock state detection device is provided with a second detection switch in the second detection portion 42, and the second detection switch is triggered by the fastener sensor and outputs a second detection signal when the lock body 1 is close to the lock body fastener 3 or away from the lock body fastener 3. Furthermore, by adopting the door lock state detection device in this embodiment, after the door body is closed, the door lock state detection device installed on the lock body 1 can detect the position of the lock tongue 2 in the lock body 1 through the first detection switch, and detect whether the door body is closed through the second detection switch, and then judge the state of the door body comprehensively based on the state of the door body and the state of the lock tongue 2, thereby improving the accuracy of door body detection and enhancing the safety of the door lock during use.

[0033] like Figure 2As shown, the first detection switch in this embodiment includes a first reed switch 81 arranged on the first detection part 41, and the lock tongue sensing member is a first magnetic member installed on the lock tongue 2. The first magnetic member approaches or moves away from the first reed switch 81 as the lock tongue 2 moves to trigger the first reed switch 81. A lock tongue mounting hole is provided on the lock tongue 2, and the first magnetic member is a lock tongue magnetic column 51 installed in the lock tongue mounting hole. The door lock state detection device also includes a PCB board 7 arranged on the mounting bracket 4, and a signal line 6 connected to the PCB board 7. The first reed switch 81 is arranged on the PCB board 7. When the door body is closed, the lock tongue 2 will extend and insert into the lock body fastener 3. At this time, the lock tongue magnetic column 51 will move with the lock tongue 2, and then be sensed by the first reed switch 81, and then the lock tongue 2 movement signal is transmitted through the signal line 6 through the first reed switch 81.

[0034] See also Figure 2 Specifically, the second detection switch includes a second reed switch 82 provided in the second detection part 42, and the fastener sensing member is a second magnetic member installed on the lock body fastener 3. The second reed switch 82 approaches or moves away from the second magnetic member as the lock body 1 moves to trigger the second reed switch 82. The second magnetic member is a fastener magnetic column 52 installed on the lock body fastener 3, and the fastener magnetic column 52 is provided on the back side of the lock body fastener 3 opposite to the second magnetic member. After the door body is closed, the second reed switch 82 in the lock body 1 will approach the lock body fastener 3, sense the fastener magnetic column 52 provided on the lock body fastener 3, and then obtain a signal of whether the door body is completely closed and can be transmitted through the signal line 6.

[0035] Specifically, the lock body 1 in this embodiment is installed and fixed on the door body, and the mounting bracket 4 is arranged outside the lock body 1, including a first mounting plate on which the first detection part 41 is arranged, and a second mounting plate on which the second detection part 42 is arranged, wherein the second mounting plate is installed on the side of the lock body 1 adjacent to the lock body fastener 3. While realizing the door body switch detection, since the door lock state detection device can realize the detection of the state of the lock tongue 2 and the lock body 1 by being installed on the outside of the lock body 1, the influence on the structure of the lock body 1 itself is greatly reduced, and the service life and accuracy of the lock body 1 are further improved.

[0036] Preferably, the first mounting plate and the second mounting plate are arranged vertically, which facilitates the arrangement of the door lock state detection device on the door lock.

[0037] Specifically, the door body in this embodiment is provided with mechanical structures or electronic structures for users to open and close the door inside and outside, and the first reed switch 81 and the second reed switch 82 are welded to the corresponding welding points on the PCB board 7, so that the reed switch can be used normally. The first detection part 41 and the second detection part 42 of the mounting bracket 4 are respectively provided with positioning columns 9, and the PCB board 7 has a fixing hole 71 corresponding to the position of the positioning column 9. After the signal line 6 passes through the wire groove of the mounting bracket 4, it is welded to the corresponding welding points on the PCB board 7, and the PCB board 7 is installed in the first detection part 41 and the second detection part 42. The welding surface of the reed switch is outward, and the width of the wire groove of the mounting bracket 4 does not protrude from the lower end of the top and bottom hooks in the lock body 1, so that the lock body 1 can be used normally. At the same time, the wire groove of the mounting bracket 4 does not protrude from the lock body 1, so that the lock body 1 can be normally installed on the door body after the mounting bracket 4 is installed.

[0038] See also Figure 1 and Figure 2 At the tail of the lock tongue 2, there are two lock tongue magnetic pillars 51 fixed in the lock tongue 2. After installation, the lock tongue 2 is normally extended and the lock tongue magnetic pillars 51 cannot be seen from the outside, which does not affect the appearance. The movement of extending and retracting the lock tongue 2 during use causes the two lock tongue magnetic pillars 51 in the lock tongue 2 to move away from and approach the first reed switch 81 in the first detection part 41 installed in the mounting bracket 4. The magnetic field of the lock tongue magnetic pillars 51 acts on the first reed switch 81, and the reed switch generates a closed or open signal, and the signal of the first reed switch 81 is obtained through the signal line 6.

[0039] On the lock body fastener 3, two fastener magnetic columns 52 are installed at a height position corresponding to the second detection portion 42 of the mounting bracket 4. After installation, they do not protrude from the outer surface of the lock body fastener 3 and do not affect the appearance. The lock body fastener 3 is installed and fixed in the door body. During the user's use, the action of opening and closing the door causes the second reed switch 82 in the second detection portion 42 in the mounting bracket 4 to move away from and approach the fastener magnetic column 52 installed on the lock body fastener 3. The magnetic field of the fastener magnetic column 52 acts on the second reed switch 82, and the second reed switch 82 generates a closed or open signal, and the signal of the second reed switch 82 is obtained through the signal line 6.

[0040] Combine the following Figure 1 and Figure 2 The working process of the door lock status detection device is described as follows:

[0041] When the door lock is in use, in the normal closed state, the lock tongue 2 extends out of the lock body 1, and the lock tongue magnetic column 51 is away from the first reed switch 81 installed in the first detection part 41. At this time, the reed of the first reed switch 81 in the first detection part 41 is in a disconnected state, and the lock tongue magnetic column 51 in the lock body fastener 3 is close to the first reed switch 81 in the first detection part 41 installed on the mounting bracket 4. At this time, the reed of the first reed switch 81 in the first detection part 41 is in a closed state. At this time, the signals of the two reed switches in the signal line 6 are read to comprehensively judge the normal state.

[0042] A: Normal state

By reading the signals of the first reed switch 81 and the second reed switch 82 in the signal line 6, it can be known that the door body is well closed and the lock tongue 2 is extended normally. Normal state.

[0044] B: Abnormal state

[0045] 1. When the user uses the mechanical structure or electronic structure arranged on the inner or outer side of the door body to close the door, if the door body is closed well but the lock tongue 2 is not extended normally for some reason, the lock tongue magnetic column 51 in the lock tongue 2 is close to the first reed switch 81 installed in the first detection part 41, and the reed of the first reed switch 81 in the first detection part 41 is in a closed state. At the same time, the fastener magnetic column 52 in the lock body fastener 3 is close to the second reed switch 82 in the second detection part 42 installed on the mounting bracket 4, and the reed of the second reed switch 82 in the second detection part 42 is in a closed state. By reading the signals of the first reed switch 81 and the second reed switch 82 in the signal line 6, it can be known that the door body is closed well but the lock tongue 2 is not extended. Abnormal state.

[0046] 2. When the user uses the mechanical structure or electronic structure arranged on the inner or outer side of the door body to close the door, if the lock tongue 2 is normally extended but the door body is not closed, the lock tongue magnetic column 51 in the lock tongue 2 is away from the first reed switch 81 installed in the first detection part 41, and the reed of the first reed switch 81 in the first detection part 41 is in a disconnected state. The fastener magnetic column 52 in the lock body fastener 3 is away from the second reed switch 82 in the second detection part 42 installed on the mounting bracket 4, and the reed of the second reed switch 82 in the second detection part 42 is in a disconnected state. By reading the signals of the first reed switch 81 and the second reed switch 82 in the signal line 6, it can be known that the lock tongue 2 is normally extended, but the door body is not closed in an abnormal state.

[0047] In addition, it should be noted that: based on the above description of this embodiment, technicians in this field can clearly know that the installation position can be changed, and the detection components in the embodiment can also be changed. Not only can it be a reed switch, but it can also be other switches such as photoelectric switches, etc. As long as the detection principle and installation method and method are similar to the principle of the device, they are all within the protection scope of this application.
