[0049] Please refer to Figures 1 to 6 , this embodiment provides a fully automatic rail transit lock, including a lock body 1, a control device 2, and a switching device 3.
[0050] The lock body 1 includes a lock housing 11 and a primary lock core 12 and a secondary lock core 13 arranged inside the lock housing 11, and the secondary lock core 13 is drivingly connected to the primary lock core 12.
[0051] The control device 2 is connected to the secondary lock core 13 and is used to control the locking or unlocking of the secondary lock core 13. The control device 2 includes a first control component 21 arranged on one side inside the door, a second control component 22 and a sensing switch 23 arranged on one side outside the door, and the sensing switch 23 is triggered by non-contact sensing elements.
[0052] The switching device 3 is arranged on one side inside the door, connected to the lock body 1 and the control device 2, and is used to control the lock body 1 to switch between an open state and a closed state.
[0053] When the lock body 1 is in the open state, the first control component 21 and the second control component 22 can control the secondary lock core 13 and the primary lock core 12 to be unlocked synchronously, and the sensing switch 23 can control the switching device 3 to switch the lock body 1 to the closed state; when the lock body 1 is in the closed state, the first control component 21 can control the secondary lock core 13 to be locked, and the sensing switch 23 can control the secondary lock core 13 to be unlocked.
[0054] Among them, when the door is closed, the lock core 12 can be automatically locked, and the secondary lock core 13 is drivingly connected to the primary lock core 12. When the secondary lock core 13 is unlocked, it can drive the primary lock core 12 to be unlocked synchronously, and the primary lock core 12 can be unlocked by a separate control member such as a handle. The transmission structure of the secondary lock core 13 and the primary lock core 12 is the transmission structure of a traditional anti-theft lock, so it will not be elaborated in this embodiment. A program chip can be built into the switching device 3, and the state of the lock body 1 can be controlled through the program, and the switching device 3 can determine the functions of the first control component 21, the second control component 22, and the sensing switch 23 in different states.
[0055] In the embodiment provided by this embodiment, in the case of the lock body 1 in the open state, the first control component 21 inside the door can unlock the secondary lock cylinder 13 and the primary lock cylinder 12 synchronously. Of course, this is in the case where the secondary lock cylinder 13 is already locked. If the secondary lock cylinder 13 is not locked, the first control component 21 only unlocks the primary lock cylinder 12. The induction switch 23 is triggered by a non-contact induction element. Specifically, the non-contact induction element can be an induction card, which can be carried by the flight attendant. The lock body 1 in the open state can be switched to the closed state through the induction switch 23. Therefore, when the flight attendant closes the door, it is necessary to swipe the card to change the state of the lock body 1. If the card is not swiped, the door can be directly opened by controlling the first control component 21, avoiding the situation where the flight attendant leaves the card indoors.
[0056] In the case of the lock body 1 in the closed state, the flight attendant inside the room can lock the secondary lock cylinder 13 by controlling the first control component 21 to double-lock the door. Only by swiping the card can the door be opened outdoors, increasing the security.
[0057] A fully automatic rail transit lock provided by this embodiment, by setting the primary lock cylinder 12 and the secondary lock cylinder 13 connected by transmission, the first control component 21 and the switching device 3 on one side inside the door, and the second control component 22 and the induction switch 23 on one side outside the door, enables the switching device 3 to control the state of the lock, and then switches the functions of the first control component 21, the second control component 22 and the induction switch 23, so that the flight attendant can open or double-lock the door through the first control component 21 when inside the room, and can open the door or switch the state of the lock by swiping the card to trigger the induction switch 23 when outside the door, and can open the door through the second control component 22 when the card is not swiped, thus avoiding the situation where the flight attendant forgets the card indoors and is more intelligent.
[0058] Further, please refer to Figure 3 , the control device 2 further includes a driving motor 24, and the driving motor 24 is connected to the secondary lock cylinder 13, the first control component 21, the second control component 22 and the switching device 3.
[0059] Among them, the first control component 21 and the second control component 22 can control the driving motor 24, and the driving motor 24 can control the locking or unlocking of the secondary lock cylinder 13. The switching device 3 can control whether the secondary lock cylinder 13 is locked or unlocked when the driving motor 24 is triggered.
[0060] Further, the switching device 3 includes a control chip 31 and a changeover switch 32.
[0061] The control chip 31 is connected to the first control component 21, the second control component 22, the induction switch 23 and the driving motor 24.
[0062] The changeover switch 32 is connected to the control chip 31.
[0063] Among them, a program can be pre-written in the control chip 31. When the control switch 32 is switched, the state of the lock body 1 can be changed through the program, so as to control the functions of the first control component 21, the second control component 22, and the induction switch 23 in different states. In the open state, both the first control component 21 and the second control component 22 can cause the drive motor 24 to lock the secondary lock cylinder 13, while the induction switch 23 can switch the lock body 1 to the closed state; in the closed state, the first control component 21 can cause the drive motor 24 to lock the secondary lock cylinder 13, while the induction switch 23 can cause the drive motor 24 to unlock the secondary lock cylinder 13.
[0064] Furthermore, in the embodiment provided in this implementation manner:
[0065] The first control component 21 includes a first touch switch 211 and a handle 212. The first touch switch 211 is electrically connected to the control chip 31. By touching the first touch switch 211, the corresponding functions in the corresponding state can be realized. The handle 212 is connected to the secondary lock cylinder 13 or the primary lock cylinder 12, and the primary lock cylinder 12 can be unlocked independently through the handle 212.
[0066] The second control component 22 includes a second touch switch 221. The second touch switch 221 is electrically connected to the control chip 31. By touching the second control component 22, the corresponding functions in the corresponding state can be realized.
[0067] Furthermore, the switch 32 is of a knob structure. When the knob structure rotates to the first position, the lock body 1 switches to the closed state, and the knob structure abuts against the handle 212 to restrict its rotation.
[0068] Among them, the knob structure can be rotated to make the lock body 1 in the open state or the closed state. When the knob structure is rotated to make the lock body 1 in the closed state, at this time, the knob structure is in the first position, and it abuts against the handle 212, so that the handle 212 cannot rotate in the closed state.
[0069] Furthermore, an abutting groove 2121 is provided on one side of the rotating end of the handle 212. The knob structure includes a knob 321, an abutting block 322, and a position microswitch 323.
[0070] The abutting block 322 is connected to the knob 321 and can rotate synchronously with the knob 321, so that when the knob 321 rotates to the first position, the abutting block 322 can abut in the abutting groove 323.
[0071] The position microswitch 323 is connected to the knob 321 and the control chip 31.
[0072] Specifically, the abutting block 322 can be a convex block such as an eccentric wheel with a convex curved surface on its outer periphery. When the knob 321 rotates to the first position, the abutting block 322 touches the position micro switch 323 while abutting against the abutting groove 2121, and the position micro switch 323 transmits a signal to the control chip 31, thereby making the lock body 1 in a closed state.
[0073] Furthermore, it further includes a display device 4, and the display device 4 includes a first display element 41 and a second display element 42.
[0074] The first display element 41 is connected to the first control component 21 and is used to indicate the state of the lock body 1 to the people indoors at this time.
[0075] The second display element 42 is connected to the second control component 22 and is used to indicate the state of the lock body 1 to the people outdoors at this time.
[0076] Furthermore, in the embodiment provided by this embodiment:
[0077] The first display element 41 is an LED lamp, and the state of the lock body 1 at this time can be obtained by the color or quantity of the lit lamp.
[0078] The second display element 42 includes a rotating disk 421. A part of the rotating disk 421 is exposed to form a display area 422. The rotating disk 421 is connected to the switching device 3 and can be driven by the switching device 3 to rotate, so as to change the display content of the display area 422.
[0079] Wherein, the rotating disk 421 is arranged inside the housing of the second control component 22. An opening is formed on the housing, and a part of the rotating disk 421 is exposed from the opening to form the display area 422. When the switching device 3 drives the rotating disk 421 to rotate, the part of the rotating disk 421 exposed from the opening changes, thereby displaying the state of the lock body 1 at this time.
[0080] Furthermore, it further includes a speaker 5. The speaker 5 is connected to the switching device 3 and is used to give a voice prompt in real time.
[0081] Furthermore, it further includes a remote control device 6. The remote control device 6 is connected to the control chip 31 through a wireless network or Bluetooth. The remote control device 6 can be a remote controller or an app installed on a mobile phone. The lock body 1 can be locked or unlocked through the remote control device 6.
[0082] Working principle:
[0083] Please refer to Figure 6A control chip 31, a drive motor 24, a secondary lock core 13 and a primary lock core 12 are installed on the door, a first touch switch 211, a switching switch 32, a first display element 41, a speaker 5 and a handle 212 are arranged on the inner side of the door, and a second touch switch 221, a sensing switch 23, a second display element 42 and a speaker 5 are arranged on the inner and outer sides.
[0084] The secondary lock cylinder 13 is transmission-connected to the primary lock cylinder 12 , and the handle 212 can unlock the primary lock cylinder 12 alone. Meanwhile, the primary lock cylinder 12 can also be unlocked synchronously when the secondary lock cylinder 13 is unlocked.
[0085] The control chip 31 is pre-written with a program, and the lock body can be switched to an open state or a closed state by switching the switch 32 .
[0086] When in the open state, the first touch switch 211 and the second touch switch 221 can unlock the secondary lock cylinder 13 and the primary lock cylinder 12 together to open the door; the lock body can be switched to the closed state by triggering the sensing switch 23 through a card.
[0087] In the closed state, the secondary lock cylinder 13 and the primary lock cylinder 12 can be unlocked together by triggering the sensing switch 23 by a card; the secondary lock cylinder 13 can be locked by touching the first touch switch 211.
[0088] In any of the above processes, the first display element 41, the second display element 42 and the speaker 5 can all provide prompts.
