Description

Technical Field

[0001] This utility model relates to hotel locks, and more particularly to a door lock with electronic deadbolt function. Background Technology

[0002] Some existing door locks suitable for hotels include a lock housing, a bolt mechanism, a handle drive mechanism, a clutch device, and a deadbolt module. The bolt mechanism includes a bolt body that is retractably connected to the lock housing and an elastic element for driving the bolt body to extend. The handle drive mechanism includes a handle lever and a transmission assembly. When the clutch is engaged, the handle lever can be driven by the clutch and transmission assembly, causing the bolt body to retract; when the clutch is disengaged, the handle lever can only rotate freely and cannot drive the bolt body to retract. The deadbolt module includes a deadbolt switch mechanism and an electric push rod. When the deadbolt switch mechanism is activated, the electric push rod can be used to restrain the position of the bolt body, preventing the door from opening. Currently, the structure of this type of door lock is still relatively complex. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a door lock with an electronic deadbolt function, which has a relatively simplified structure.

[0004] A door lock with electronic deadbolt function according to an embodiment of the present invention includes a lock housing, a bolt mechanism, a handle drive mechanism, a control module, and a deadbolt switch mechanism. The bolt mechanism is disposed on the lock housing and includes a bolt body and a first elastic element. The bolt body is retractably disposed on the lock housing, and the first elastic element drives the bolt body to extend. The handle drive mechanism is disposed on the lock housing and includes a handle lever and a transmission assembly. The handle lever is rotatably disposed on the lock housing, and the transmission assembly is in transmission cooperation with the bolt mechanism. A clutch device is disposed on the lock housing and has an engaged state and a disengaged state. In the engaged state, the handle lever is in transmission cooperation with the transmission assembly through the clutch device; in the disengaged state, the handle lever is in an idle position. The deadbolt switch mechanism is closable disposed on the lock housing and electrically connected to the clutch device. The deadbolt switch mechanism and the clutch device form an electronic deadbolt module. When the bolt body extends, the deadbolt switch mechanism can be activated, preventing the clutch device from switching to the engaged state.

[0005] The door lock with electronic deadbolt function according to the present utility model embodiment has at least the following beneficial effects: the electronic deadbolt module is formed by combining the deadbolt switch mechanism and the clutch device. When the lock tongue is extended, if the user inside the room needs to deadbolt the door, the deadbolt switch mechanism can be activated to directly restrict the clutch device from switching to the engaged state, so that the handle head is kept in the free-spinning position. At this time, the door cannot be opened by unauthorized personnel, thus forming the electronic deadbolt function. The electronic deadbolt module uses the clutch device itself to generate the deadbolt function without the need for an additional actuator to realize the deadbolt function, thereby simplifying the door lock structure.

[0006] According to some embodiments of this utility model, a card reader controller is also included. The card reader controller is disposed in the lock housing and electrically connected to the clutch device. The card reader controller can read the first sensor card or the second sensor card. When the deadbolt switch mechanism is closed, the card reader controller can read the first sensor card or the second sensor card and drive the clutch device to switch to the engaged state. When the deadbolt switch mechanism is activated, the card reader controller can read the second sensor card and drive the clutch device to switch to the engaged state.

[0007] According to some embodiments of the present invention, the deadbolt switch mechanism includes a deadbolt sensing head and a detection switch. The deadbolt sensing head is rotatably disposed on the lock housing and has a reset position and a deadbolt position. The detection switch is used to detect the position of the deadbolt sensing head. The detection switch is electrically connected to the clutch device. When the lock tongue is in the extended position, the deadbolt sensing head is allowed to rotate from the reset position to the deadbolt position.

[0008] According to some embodiments of this utility model, the detection switch is a micro switch. In the reset position, the anti-locking sensing head presses the micro switch; in the anti-locking position, the anti-locking sensing head separates from the micro switch.

[0009] According to some embodiments of this utility model, during the retraction of the locking tongue, the anti-locking sensor head can be driven to rotate from the anti-locking position to the reset position.

[0010] According to some embodiments of this utility model, the latch mechanism further includes a latch transmission component, which is rotatably connected to the lock housing and drives the latch body. The latch transmission component is also driven by the transmission assembly. When the latch transmission component rotates, it can drive the latch body to extend or retract. A first elastic element is disposed between the lock housing and the latch transmission component. The first elastic element is used to drive the latch transmission component to rotate in the forward direction and extend the latch body. When the latch transmission component rotates in the reverse direction, it can drive the latch body to retract and push the anti-locking sensor head to rotate from the anti-locking position to the reset position.

[0011] According to some embodiments of the present invention, the rotation axis of the anti-lock sensing dial is collinear with the rotation axis of the latch transmission member, and the latch transmission member is provided with a first push block, which is circumferentially opposite to the anti-lock sensing dial along the rotation axis of the latch transmission member.

[0012] According to some embodiments of this utility model, the lock housing is rotatably provided with a reset dial, and the reset dial is provided with a toggle block. When the lock tongue is in the extended position, the reset dial can push the lock tongue transmission component to rotate in the opposite direction through the toggle block.

[0013] According to some embodiments of this utility model, the transmission assembly includes an unlocking dial and a transmission frame; the clutch device includes a clutch element, a reset elastic element, and a clutch driver; the unlocking dial is rotatably connected to the lock housing; the rotation axis of the unlocking dial is collinear with the rotation axis of the handle dial; the transmission frame is slidably disposed on the lock housing and can drive the bolt body to retract; the unlocking dial can drive the transmission frame to slide; the clutch element is slidably disposed on the unlocking dial; in the engaged state, the clutch element is connected to the handle dial so that the unlocking dial and the handle dial rotate synchronously; in the disengaged state, the clutch element is separated from the handle dial; the reset elastic element is disposed on the unlocking dial and is used to drive the clutch element to slide to a position separated from the handle dial; the clutch driver is used to drive the clutch element to slide to a position connected to the handle dial; the clutch driver is electrically connected to the deadbolt switch mechanism and the card reader controller.

[0014] According to some embodiments of the present invention, a latch mechanism is also included. The latch mechanism is disposed on the lock housing. The latch mechanism includes a latch body and a second elastic member. The latch body is retractably disposed on the lock housing. The second elastic member is used to drive the latch body to extend.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0030] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0031] Reference Figures 1 to 3 This utility model discloses a door lock with electronic deadbolt function, comprising a lock housing 100, a bolt mechanism 200, a handle drive mechanism 300, a control module, and a deadbolt switch mechanism 500. The bolt mechanism 200 is disposed on the lock housing 100 and includes a bolt body 210 and a first elastic element 220. The bolt body 210 is retractably disposed on the lock housing 100, and the first elastic element 220 drives the bolt body 210 to extend. The handle drive mechanism 300 is disposed on the lock housing 100 and includes a handle lever 310 and a transmission assembly 320. The handle lever 310 is rotatably disposed on the lock housing 100, and the transmission assembly 320 is in transmission cooperation with the bolt mechanism 200. A clutch device 400 is disposed on the lock housing 100. The lock housing 100 has an engaged state and an disengaged state. In the engaged state, the handle 310 is engaged with the transmission assembly 320 via the clutch 400. In the disengaged state, the handle 310 is in an idle position. The deadbolt switch mechanism 500 is closably disposed on the lock housing 100 and electrically connected to the clutch 400. The deadbolt switch mechanism 500 and the clutch 400 form an electronic deadbolt module. When the bolt 210 is extended, the deadbolt switch mechanism 500 can be activated to prevent the clutch 400 from switching to the engaged state.

[0032] An electronic deadbolt module is formed by combining a deadbolt switch mechanism 500 and a clutch device 400. When the bolt body 210 is extended, if the user inside the room needs to deadbolt the door, the deadbolt switch mechanism 500 can be activated to directly restrict the clutch device 400 from switching to the engaged state, so that the handle head 310 remains in the free-spinning position. At this time, the door cannot be opened by unauthorized personnel, thus forming an electronic deadbolt function. The electronic deadbolt module uses the clutch device 400 itself to generate the deadbolt function without the need for an additional actuator, thereby simplifying the door lock structure.

[0033] In this embodiment, a card reader controller is also included. The card reader controller is disposed in the lock housing 100 and electrically connected to the clutch device 400. The card reader controller can read the first sensor card or the second sensor card. When the deadbolt switch mechanism 500 is closed, the card reader controller can read the first sensor card or the second sensor card and drive the clutch device 400 to switch to the engaged state. When the deadbolt switch mechanism 500 is activated, the card reader controller can read the second sensor card and drive the clutch device 400 to switch to the engaged state.

[0034] Specifically, the first access card is a guest card, and the second access card is the room owner card corresponding to that room.

[0035] When the deadbolt switch mechanism 500 is closed, the card reader can read two types of cards and switch the clutch device 400 to the engaged state. Then, the handle can be turned to unlock the door, preventing unauthorized personnel from unlocking it. When the deadbolt switch mechanism 500 is open, the card reader can only use the second sensor card to switch the clutch device 400 to the engaged state. Then, the handle can be turned to unlock the door, preventing unauthorized personnel from unlocking it. This further improves security and the flexibility of the door lock, making it suitable for complex usage scenarios such as hotels.

[0036] Specifically, the second access card can also be a master security card. When guests are unable to open the door themselves in an emergency, hotel staff can use the master security card to unlock and open the door.

[0037] In this embodiment, the deadbolt switch mechanism 500 includes a deadbolt sensing dial 510 and a detection switch 520. The deadbolt sensing dial 510 is rotatably mounted on the lock housing 100 and has a reset position and a deadbolt position. The detection switch 520 is used to detect the position of the deadbolt sensing dial 510. The detection switch 520 is electrically connected to the clutch device 400. When the latch body 210 is in the extended position, the deadbolt sensing dial 510 is allowed to rotate from the reset position to the deadbolt position.

[0038] The electronic deadbolt function is controlled by detecting the position of the deadbolt sensor dial 510 via the detection switch 520. The switch structure is relatively simple and easy to implement. Specifically, the user inside the room can turn the deadbolt sensor dial 510 to open or close the deadbolt switch mechanism 500, thereby opening or closing the electronic deadbolt module, which is relatively convenient to use.

[0039] It is conceivable that in other embodiments, the deadbolt switch mechanism 500 may also be directly linked to the latch body 210. When the latch body 210 extends, the deadbolt switch mechanism 500 is directly activated; when the latch body 210 retracts, the deadbolt switch mechanism 500 is directly deactivated.

[0040] In this embodiment, the detection switch 520 is a micro switch. In the reset position, the deadbolt sensing head 510 presses the micro switch; in the deadbolt position, the deadbolt sensing head 510 separates from the micro switch. The deadbolt switch uses a micro switch, and by rotating the deadbolt sensing head 510, the micro switch is pressed or released, thereby closing and actuating the deadbolt switch mechanism 500. The structure of the deadbolt switch is relatively simple and easy to implement. When the deadbolt sensing head 510 presses the micro switch, the deadbolt switch mechanism 500 is closed; conversely, when it is released, the deadbolt switch mechanism 500 is open. It is conceivable that in other embodiments, the detection switch 520 could also be, for example, a push-button switch or a rotary switch; those skilled in the art can choose according to actual needs.

[0041] In this embodiment, the retraction of the latch 210 drives the deadbolt sensor 510 to rotate from the deadbolt position to the reset position. When the room card is swiped by the card reader outside the door, or when someone inside the room opens the door directly, the latch 610 retracts. During the retraction of the latch 610, the deadbolt sensor 510 is directly driven to rotate to the reset position, thus preventing the problem of hotel staff being unable to enter the room to clean or deliver food if the user forgets to turn off the electronic deadbolt module when leaving.

[0042] In this embodiment, the latch mechanism 200 further includes a latch transmission member 230, which is rotatably connected to the lock housing 100 and drives the latch body 210. The latch transmission member 230 is also connected to the transmission assembly 320. When the latch transmission member 230 rotates, it can drive the latch body 210 to extend or retract. A first elastic member 220 is disposed between the lock housing 100 and the latch transmission member 230. The first elastic member 220 is used to drive the latch transmission member 230 to rotate in the forward direction and extend the latch body 210. When the latch transmission member 230 rotates in the reverse direction, it can drive the latch body 210 to retract and push the anti-locking sensor dial 510 from the anti-locking position to the reset position.

[0043] The locking tongue mechanism 200 has a relatively simple and compact structure because the locking tongue transmission component 230 rotates to drive the locking tongue body 210 to extend and retract.

[0044] Specifically, the first elastic element 220 is a torsion spring, and the latch transmission component 230 drives the latch body 210 to extend and retract via a sliding block structure. It is conceivable that in other embodiments, the first elastic element 220 could also be a spring or a sheet, with one end abutting against the latch body 210 and the other end abutting against the lock housing 100, directly pushing the latch body 210 out. In this case, the transmission component 320 can drive the latch body 210 to retract via the sliding block structure.

[0045] In this embodiment, the rotation axis of the deadbolt sensor 510 is collinear with the rotation axis of the latch transmission member 230. The latch transmission member 230 is provided with a first push block 231, which is circumferentially opposite to the deadbolt sensor 510 along the rotation axis of the latch transmission member 230. During the reverse rotation of the latch transmission member 230, the latch body 210 is driven to retract. Since the first push block 231 and the deadbolt sensor 510 are circumferentially opposite to each other along the rotation axis of the latch transmission member 230, and the deadbolt sensor 510 and the latch transmission member 230 are coaxially arranged, the deadbolt sensor 510 can be pushed to the reset position by the first push block 231 when the latch transmission member 230 rotates, thereby automatically closing the deadbolt switch mechanism 500.

[0046] It is conceivable that in other embodiments, a first push block 231 may be provided on the deadbolt sensor 510, so that when the lock tongue transmission member 230 rotates in the reverse direction, the deadbolt sensor 510 is reset by pushing the first push block 231.

[0047] It is conceivable that in some other implementations, during the retraction of the locking tongue 210, the locking tongue 210 can also be used to push the anti-locking sensor dial 510 to reset and rotate.

[0048] In this embodiment, the transmission assembly 320 includes an unlocking dial 321 and a transmission frame 322. The clutch device 400 includes a clutch element 410, a reset elastic element, and a clutch driver 420. The unlocking dial 321 is rotatably connected to the lock housing 100. The rotation axis of the unlocking dial 321 is collinear with the rotation axis of the handle dial 310. The transmission frame 322 is slidably disposed on the lock housing 100 and can drive the lock tongue 210 to retract. The unlocking dial 321 can drive the transmission frame 322 to slide. The clutch element 410 is slidably disposed on the unlocking dial 321. In the engaged state, the clutch 410 is connected to the handle lever 310, causing the unlocking lever 321 and the handle lever 310 to rotate synchronously. In the disengaged state, the clutch 410 is separated from the handle lever 310. A reset elastic element is disposed on the unlocking lever 321 and is used to drive the clutch 410 to slide to the position where it is separated from the handle lever 310. The clutch driver 420 is used to drive the clutch 410 to slide to the position where it is connected to the handle lever 310. The clutch driver 420 is electrically connected to the deadbolt switch mechanism 500 and the card reader controller. The aforementioned transmission assembly 320 and clutch device 400 have a simple and compact structure and good performance.

[0049] Specifically, when the unlocking lever 321 rotates, the push transmission frame 322 slides up and down, and the transmission frame 322 pushes the lock tongue transmission component 230 to rotate, causing the lock tongue body 210 to retract. The handle lever 310 has a clutch socket, and the clutch actuator 420 is a linear actuator, such as a small magnetostrictive actuator or a small linear motor. By pushing the clutch component 410 into the clutch socket, it enters the engaged state, causing the handle lever 310 and the clutch lever to rotate synchronously, so that the door can be opened by rotating the handle. The reset elastic element is a spring. When the clutch actuator 420 is closed, the spring pushes the clutch component 410 out of the clutch socket, causing the clutch device 400 to enter the disengaged state. At this time, the handle lever 310 is in the free-spinning position.

[0050] It is conceivable that in other embodiments, the transmission assembly 320 may also include an unlocking lever 321 and a linkage assembly. The unlocking lever 321 engages with the bolt body 210 via the linkage assembly to drive the bolt body 210 to extend or retract. The clutch device 400 may also have other structures, such as an electric push rod. One end of the electric push rod is fixed to the unlocking lever 321, and the extension rod of the electric push rod can be inserted into or disengaged from the clutch socket of the handle lever 310 to achieve engagement or disengagement. There are many types of clutch devices 400 in door locks, and no limitation is made here.

[0051] It also includes a latch mechanism 600, which is disposed on the lock housing 100. The latch mechanism 600 includes a latch body 610 and a second elastic member 620. The latch body 610 is telescopically disposed on the lock housing 100, and the second elastic member 620 is used to drive the latch body 610 to extend. The handle drive mechanism 300 can drive the latch body 610 to retract. The latch mechanism 600 improves the security of the door lock.
