[0002] As people's needs for access control systems evolve in different scenarios, door lock designs are becoming increasingly diverse. Doors can be categorized by the number of leaves, typically single-leaf, double-leaf, or double-leaf doors. Double-leaf doors have one wide door, called the main door, and a narrower, called the sub-door. The main door is equipped with a door lock and handle, allowing it to be opened and closed relative to the sub-door. The sub-door is equipped with a latch, typically locked in place by the building wall or door frame. In current access control systems, sub-doors can be automatically locked and unlocked using an electric latch.

[0003] However, when an electric bolt is in adverse working conditions such as power outage / power failure, motor damage, damage or jamming of the motor transmission rack / gear (reduction box), the electric bolt may not work properly due to the failure of the motor drive, causing the door control system to be unable to open / close the access channel provided by the door leaf, and it lacks reliability and safety.

In a specific embodiment, Figure 1 For example, four fixing plates 15 are provided, and the four fixing plates 15 are provided in the four inner corner areas of the latch box 1; there are two fixing plates 15 used only to connect the main frame 11 and the cover plate 12, and the fixing plates 15 are provided in a U-shaped structure, and one fixing plate 15 has two connecting holes, one connecting hole connects the main frame 11 and the fixing plate 15 through the first locking member 16, and the other connecting hole connects the cover plate 12 and the fixing plate 15 through the first locking member 16, thereby fixing the main frame 11 and the cover plate 12 together; it is only used to connect the main frame 11 and the cover plate 12. There are two fixing plates 15 for the plate 12 and the latch panel 13. The fixing plates 15 are arranged in a U-shaped structure. One fixing plate 15 has three connecting holes. One connecting hole connects the main frame 11 and the fixing plate 15 through a first locking member 16, another connecting hole connects the latch panel 13 and the fixing plate 15 through a second locking member 18, and the third connecting hole connects the cover plate 12 and the fixing plate 15 through the first locking member 16, thereby fixing the main frame 11, the cover plate 12 and the latch panel 13 together. Of course, more fixing plates 15 can be provided.

[0053] In this embodiment, the locking mechanism provides an automatic locking scheme and an automatic unlocking scheme; the driving component is installed in the latch box 1, the upper locking component and the lower locking component are slidably arranged in the latch box 1, and the linkage member 24 is transmission-connected between the upper locking component and the lower locking component to link the upper locking component and the lower locking component to slide; the upper locking component or the lower locking component is arranged on the driving path of the driving component.

[0054] See also Figure 1 and Figure 3 The upper locking component includes an upper locking slide 221 and an upper locking hook 222. The upper locking slide 221 is slidably arranged in the latch box 1. One end of the upper locking hook 222 is fixedly connected to the upper locking slide 221, and the other end passes through the latch box 1 and extends to the external space of the latch box 1; the lower locking component includes a lower locking slide 231 and a lower locking hook 232. The lower locking slide 231 is slidably arranged in the latch box 1. One end of the lower locking hook 232 is fixedly connected to the lower locking slide 231, and the other end passes through the latch box 1 and extends to the external space of the latch box 1.

[0055] In this embodiment, a manual unlocking solution is provided by an unlocking assembly; the unlocking assembly includes a fixedly connected lever 31 and a paddle 32, the lever 31 can be rotated to engage or deviate from the latch panel 13, the lever 31 has an operating end and a transmission end that are relatively set, the paddle 32 is connected to the transmission end, and the operating end is suitable for deviating from the extension plane of the latch panel 13 when the lever 31 rotates relative to the latch panel 13, so that the transmission paddle 32 acts on the upper locking component and the lower locking component to slide and jointly unlock the central control latch.

[0056] As an exemplary embodiment, the driving component drives the lower locking component, which then drives the upper locking component via the linkage member 24 to implement automatic locking or unlocking. The driving component is suitable for driving the lower locking sliding member 231 to slide.

[0057] As a specific implementation, see Figure 10 The lower locking slider 231 is provided with a force transmission portion 2311, which is arranged on the driving path of the driving component and the movement path of the paddle 32. The unlocking portion 2312 is adapted to slide and abut against the paddle 32. In this manner, the automatic locking and unlocking paths and the manual unlocking path share a common path, which can improve the structural integration.

[0058] As another specific embodiment, see Figure 6The lower locking slider 231 is provided with a force transmission portion 2311 and an unlocking portion 2312. The force transmission portion 2311 and the unlocking portion 2312 are spaced apart from each other. The force transmission portion 2311 is provided on the driving path of the driving component, and the unlocking portion 2312 is provided on the motion path of the paddle 32. The unlocking portion 2312 is adapted to slide and abut against the paddle 32. The spaced apart arrangement of the force transmission portion 2311 and the unlocking portion 2312 prevents interference between the automatic locking and unlocking paths and the manual unlocking path.

[0059] In some embodiments, see Figure 5 The locking slide 221 includes a firing portion 2211, an upper guide portion 2212 and an upper rack portion 2213. The firing portion 2211 is used to contact the micro switch 43 so that the micro switch 43 can detect the position information of the locking slide 221; the upper guide portion 2212 is used to slide with the cover plate 12, and two upper guide portions 2212 can be provided to improve the sliding movement accuracy of the locking slide 221; the upper rack portion 2213 is used to transmit with the linkage member 24.

[0060] In some embodiments, see Figure 6 and Figure 10 The lower locking sliding member 231 also includes a lower guide portion 2313, a lower rack portion 2314 and a connecting portion 2315. The lower guide portion 2313 is used to slide with the cover plate 12. Two lower guide portions 2313 can be provided to improve the sliding movement accuracy of the lower locking sliding member 231; the upper rack portion 2213 is used to transmit with the linkage member 24; the connecting portion 2315 is used to connect the reset component.

[0061] See also Figure 1 The drive components include a locking drive member 211, an output force transmission member 212, a moving member 213, and a release member 214. The locking drive member 211 and the output force transmission member 212 are installed in the latch box 1. The output force transmission member 212 and the moving member 213 are in driving connection. The moving member 213 is slidably connected to the latch box 1. The release member 214 is mounted on the moving member 213. Under the driving action of the locking drive member 211, the release member 214 is adapted to slide synchronously with the moving member 213 and abut against the force transmission portion 2311, thereby causing the upper and lower locking members to unlock the central control latch. When the locking mechanism is automatically unlocked, the moving plate 2131 and the release member 214 can jointly drive the lower lock sliding member 231 to slide synchronously.

[0062] In some embodiments, the locking driver 211 is configured as a drive reduction motor, the output transmission member 212 is configured as an output gear connected to the output end of the drive reduction motor, and the moving member 213 is provided with meshing teeth 2132 that mesh with the output gear for transmission. A mounting base 216 is fixed within the latch box 1, and the locking driver 211 and the mounting base 216 are fixedly disposed.

[0063] In this embodiment, the release member 214 and the moving member 213 are movably connected; as a preferred embodiment, see Figure 4 The release member 214 includes an action portion 2141 and a guide wall 2142 that are fixedly connected. The action portion 2141 is suitable for approaching the abutment force transmission portion 2311 or moving away from the release force transmission portion 2311 on the moving path of the moving member 213.

[0064] In some embodiments, see Figure 13 The guide wall 2142 has a guide surface extending toward the force transmission part 2311. The paddle 32 is suitable for sliding and abutting against the guide surface under the transmission action of the paddle rod 31. After the action part 2141 on the release member 214 is dislocated and exits the working position, the paddle 32 abuts against the force transmission part 2311 to implement manual unlocking.

[0065] In some embodiments, see Figure 4 The guide wall 2142 has a guide surface extending toward the unlocking portion 2312. The paddle 32 is adapted to slide against the guide surface under the action of the lever 31, thereby abutting the unlocking portion 2312. When the locking mechanism is automatically unlocked, the action portion 2141 contacts the force transmission portion 2311 of the lower lock slider 231, causing the lower lock slider 231 to move. When the user manually unlocks the lock using the unlocking assembly, the guide wall 2142 guides the paddle 32, ensuring that it can reliably abut the unlocking portion 2312.

[0066] As a preferred technical solution, see Figure 4 The movable member 213 comprises a fixedly connected movable plate 2131, an assembly plate 2133, and a connecting plate 2134. The connecting plate 2134 is bent and disposed on the movable plate 2131. The assembly plate 2133 is connected to the side of the connecting plate 2134 away from the movable plate 2131. The movable plate 2131 and the assembly plate 2133 are spaced relative to each other to form a mounting space for the release member 214. The release member 214 and the assembly plate 2133 are fixedly connected. This arrangement creates a partially shielded space through the movable plate 2131, the assembly plate 2133, and the connecting plate 2134, which helps block external interference and ensures smooth operation of the drive and unlocking paths.

[0067] As a specific implementation method, see Figure 4 and Figure 6 The release member 214 and the movable plate 2131 are spaced apart, and the lower locking slide 231 is mounted between the release member 214 and the movable plate 2131. The force transmission portion 2311 and the unlocking portion 2312 are respectively provided as protrusions on the side of the lower locking slide 231 facing the release block. In other embodiments, the force transmission portion 2311 can be provided as the end of a groove, and the release block can be provided with a protrusion that slides within the groove. When the locking mechanism is automatically unlocked, the protrusion abuts against the end of the groove to transmit force.

[0068] As a further technical solution, see Figures 11 to 13 The drive component also includes an elastic member 215, which is crimped and disposed between the release member 214 and the movable member 213. The movable member 213 is provided with a sliding groove structure, through which the release member 214 and the movable member 213 are slidably arranged. The paddle 32 is adapted to contact the release member 214 and compress the elastic member 215. The release member 214 can slide through the sliding groove structure, causing the action portion 2141 and the force transmission portion 2311 to be dislocated and disengaged, so that the paddle 32 contacts the force transmission portion 2311. This structure enables the automatic locking and unlocking structure of the drive component to exit the working position and facilitate the manual unlocking structure to enter the working position. During manual unlocking, the paddle 32 acts on the release member 214 to slide along the guide surface and compress the elastic member 215. After the paddle 32 is manually unlocked and withdrawn, the elastic member 215 acts on the release member 214 to slide back, causing the action portion 2141 to enter the working position. Specifically, the elastic member 215 may be crimped and disposed between the releasing member 214 and the connecting plate 2134 of the moving member 213 .

[0069] In a specific embodiment, see Figure 12 and Figure 13 The chute structure includes a first chute 2135, a second chute 2136, and a third chute 2137. The first chute 2135 and the second chute 2136 are provided on the movable plate 2131, and the third chute 2137 is provided on the assembly plate 2133. The release member 214 is provided with three sliding posts 2143, which are respectively slidably connected to the three chute structures. The first chute 2135 is configured as a closed slot, while the second chute 2136 and the third chute 2137 are configured as semi-closed slots to facilitate disassembly and assembly between the release member 214 and the movable member 213.

[0070] As a further technical solution, see Figure 4The drive component also includes an elastic member 215, which is crimped and disposed between the release member 214 and the assembly plate 2133 of the movable member 213. The elastic member 215 is used to elastically force the release member 214 toward the lower locking slide 231. The paddle 32 is adapted to contact the release member 214 and compress the elastic member 215, causing the action portion 2141 and the force transmission portion 2311 to disengage from each other, thereby causing the automatic locking and unlocking mechanism of the drive component to exit the working position and facilitate the manual unlocking mechanism to enter the working position. The elastic member 215 establishes a flexible connection between the release member 214 and the lower locking slide 231, acting as a flexible buffer when the drive member contacts the lower locking slide 231 and slides, thereby extending the service life of the transmission mechanism between the drive member and the lower locking slide 231. In a specific embodiment, two elastic members 215 are provided, which can strengthen the alignment of the release member 214 with the lower locking slide 231, thereby improving assembly accuracy.

[0071] In some embodiments, the linkage member 24 is configured as a lock hook gear; the lock hook gear and the upper rack portion 2213 and the lower rack portion 2314 are respectively engaged with each other for transmission, and a shaft body that is rotatably connected to the lock hook gear is provided on the main frame 11.

[0072] As a preferred technical solution, see Figure 1 and Figure 3 The locking mechanism also includes a reset component, which includes a reset spring 251 and a reset bracket 252. The reset bracket 252 is installed in the latch box 1. The reset spring 251 is sleeved on the reset bracket 252. One end of the reset spring 251 is connected to the reset bracket 252, and the other end of the reset spring 251 is connected to the lower locking component, specifically the lower lock slider 231. The reset spring 251 is used to reset the lower lock slider 231. During automatic unlocking, the driving component causes the lower locking component to move and compress the reset spring 251. During automatic locking, the driving component causes the lower locking component to reset, and at the same time, the reset spring 251 elastically resets the lower lock slider 231. During manual unlocking, the paddle 32 causes the lower locking component to move and compress the reset spring 251. After manual unlocking, the reset spring 251 resets the lower lock slider 231, allowing the locking mechanism to automatically and smoothly lock.

[0073] As a preferred embodiment, the latch box 1 is provided with a guide structure for guiding the sliding movement of the locking mechanism. The guide structure includes guide grooves provided on the cover plate 12. The guide grooves are provided corresponding to the upper guide portion 2212 and the lower guide portion 2313 and are slidably connected. On the one hand, the guide grooves guide the upper guide portion 2212 and the lower guide portion 2313, allowing the upper locking slide 221 and the lower locking slide 231 to slide in an aligned manner. On the other hand, the guide grooves limit the movement of the upper locking slide 221 and the lower locking slide 231 to the extreme positions, ensuring the rationality and reliability of the movement range. Figure 1 The guide structure also includes a guide column 14 arranged in the latch box 1, which is fixedly connected to the main bracket 11. The guide column 14 can be used to guide the sliding of the limiting moving part 213 in the latch box 1. A guide groove can be set on the moving part 213, and the guide column 14 is provided with the guide groove.

[0074] In some embodiments, the central control latch further includes a control component, see Figure 1 The control assembly includes a control circuit board 41, a push button switch 42, and a micro switch 43. The control circuit board 41 and the micro switch 43 are installed in the latch box 1. The control circuit board 41 is electrically connected to the drive component, the control circuit board 41 is electrically connected to the push button switch 42, and the control circuit board 41 is electrically connected to the micro switch 43. The micro switch 43 is used to obtain the working position of the locking mechanism. The micro switch 43 is arranged on the sliding path of the upper locking component or the lower locking component. In a specific implementation process, when the micro switch 43 is triggered, it can indicate that the automatic unlocking is in place, controlling the closing of the locking drive 211. The push button switch 42 is installed on the latch panel 13 for user triggering operation.

[0075] In a specific embodiment, see Figure 1 A sealing plate 17 is provided in the latch box 1. The sealing plate 17 is provided adjacent to the latch panel 13. The sealing plate 17 can be used to install the driving rod 31. The latch panel 13 is provided with a mounting notch for the driving rod 31. When the driving rod 31 is rotated, the user can see the inside of the latch box through this notch. The sealing plate 17 closes and blocks this notch to avoid the inside; and the sealing plate 17 can limit the driving rod 31 so that the driving rod 31 is flush with the horizontal plane of the latch panel 13.

[0076] The central control latch provided in this embodiment provides an automatic locking scheme and an automatic unlocking scheme by the locking mechanism; specifically, Figure 1 and Figure 3For example, the locking drive member 211 is controlled to drive the output force transmission member 212 to rotate, and the output force transmission member 212 drives the moving member 213 to move up and down; when the moving member 213 moves up and down, the release member 214 can squeeze / release the lower locking slide 231, so that the lower locking slide 231 and the lower locking hook 232 move up and down, thereby realizing the opening and closing of the lower end pin; the lower locking slide 231 drives the upper locking slide 221 and the upper locking hook 222 through the linkage member 24, and moves up and down synchronously to realize the opening and closing of the upper end pin; at the same time, the micro switch 43 will detect whether the upper locking slide 221 has moved into place, and feed back the signal to the control circuit board 41, and the control circuit board 41 can control the output parameters of the locking drive member 211 according to the signal.

[0077] As a variation, the upper locking member is driven by the driving member, and then the upper locking member is linked to the lower locking member through the linkage member 24 to implement automatic locking or unlocking. The driving member is suitable for driving the locking sliding member 221 to slide.

[0078] The central control latch provided in this embodiment provides a manual unlocking solution by the unlocking component. Specifically, Figures 1 to 3 The lower lock slide 231 drives the upper lock slide 221 and the upper lock hook 222 to move upward synchronously through the linkage component 24, realizing the closing of the upper end latch.

[0079] When the locking drive member 211 resumes operation, the locking drive member 211 will drive the output force transmission member 212 to return to the initial position, and the release member 214 will be reset to the initial position. At this time, the electric switch can work normally.

[0080] The central control latch provided in this embodiment provides an automatic locking scheme and an automatic unlocking scheme through the locking mechanism. The driving component drives the upper locking component or the lower locking component to slide in the latch box 1, and the upper locking component and the lower locking component are linked by the linkage member 24, so that the locking mechanism implements automatic locking and unlocking; a manual unlocking scheme is provided by the unlocking component. The user operates the lever 31 to rotate relative to the latch panel 13, and causes the lever 31 to drive the paddle 32 to slide the upper locking component and the lower locking component to jointly unlock the central control latch. This setting can solve the problem that the electric latch cannot work normally due to a motor drive failure, causing the door control system to be unable to open / close the access channel provided by the door leaf, thereby improving the reliability and safety of the central control latch.

[0081] This embodiment also provides a door control system, including the central control latch. The door control system has good reliability and safety.

[0082] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
