Abstract
Description
Technical Field
[0001] This utility model belongs to the field of smart lock technology, and relates to a clutch mechanism that can control the handle to be always open and a smart lock panel. Background Technology
[0002] When a user wants to open the door from the outside, after unlocking it with a fingerprint or password, the bolt will automatically extend and close the door after a few seconds. However, when the user is cleaning or unpacking packages at the door and needs to stay there for several minutes or even longer, the door will automatically lock itself, requiring the user to re-enter their fingerprint or password to unlock it. This type of smart lock cannot remain open all the time, making it inconvenient to use.
[0003] This type of smart lock generally includes a lock body installed inside the door and panels installed on both sides of the door. The panels include an outer panel and an outer handle installed on the outside of the door, and an inner panel and an inner handle installed on the inside of the door. A square steel bar is installed on the lock body. The outer handle is connected to the square steel bar through a clutch mechanism. After the fingerprint or password is correctly entered outside the door, the clutch mechanism drives the outer handle to be fixed to the square steel bar. Rotating the outer handle drives the square steel bar to rotate synchronously to open the door. After locking, the clutch mechanism drives the outer handle to separate from the square steel bar. The outer handle cannot unlock the door by spinning freely.
[0004] Since the aforementioned clutch mechanism is installed on the outer panel, if criminals forcibly remove the outer panel of the door lock, exposing the square steel on the lock body, they can directly rotate this square steel to unlock the door, resulting in poor anti-theft performance. Utility Model Content
[0005] The first objective of this invention is to address the aforementioned problems of existing smart locks by proposing a clutch mechanism that allows the handle to be kept open.
[0006] The first objective of this utility model can be achieved through the following technical solution:
[0007] A clutch mechanism that can control the handle to be normally open is provided on a door lock panel. The handle is rotatably provided on the panel. The clutch mechanism includes a control plate, a lever, and a limiting member. The control plate is fixedly connected to the handle, and the lever and the limiting member are rotatably provided on the panel.
[0008] The control panel has a locking position, and the lever has a locking part that can cooperate with the locking position to lock the handle position. The panel has a driving component to drive the lever to rotate so that the locking part can be removed from the locking position and the handle can be released.
[0009] The clutch mechanism also includes an elastic element one and an elastic element two. The elastic element one is used to drive the paddle to rotate in the direction that makes the locking part engage with the locking position limit. The limit member is provided with a limit part. When the locking part is out of the locking position, the elastic element two drives the limit part to move to the rotation path of the paddle to prevent the locking part from engaging with the locking position limit, so as to keep the handle in the open state.
[0010] The control panel is provided with a guide. When the handle is lifted and reversed, the guide moves to abut against the limiting member and pushes the limiting member to rotate, so that the limiting part moves out of the rotation path of the lever. When the handle is rotated to reset, the locking part and the locking position can cooperate to lock the handle.
[0011] In the aforementioned clutch mechanism with a controllable normally open handle, the panel is an inner panel, the handle is an inner handle, and the inner panel is installed on the inside of the door.
[0012] In the aforementioned clutch mechanism with a controllable normally open handle, the driving component is connected to a motor drive.
[0013] In the aforementioned clutch mechanism with a normally open controllable handle, the lever is further provided with an extension that passes through the panel and extends beyond it. The lever is rotated by moving the extension. When the user is inside the door, the lever can be unlocked by moving the extension.
[0014] In the aforementioned clutch mechanism with a controllable normally open handle, the extension includes a pull rod, a long slot is provided on the panel, one end of the pull rod is mounted on the lever, and the other end extends out of the long slot.
[0015] In the aforementioned clutch mechanism with a normally open controllable handle, the extension includes a pin, and an arc-shaped groove is provided on the panel. One end of the pin is set on the lever, and the other end extends out of the arc-shaped groove. When the lever rotates back and forth, the pin moves back and forth synchronously along the arc-shaped groove.
[0016] In the aforementioned clutch mechanism with a controllable normally open handle, the control plate has two mounting holes for installing guide components. The panel has a handle shaft that is fixedly connected to the handle. The two mounting holes are symmetrically arranged above and below the handle shaft. The guide component is installed in one of the mounting holes, and the installation position of the guide component corresponds to the installation direction of the handle on the outside of the panel.
[0017] In the aforementioned clutch mechanism with a controllable normally open handle, the guide component includes a guide post mounted on the control panel; when the handle is reversed upwards, the outer wheel surface of the guide post abuts against the limiting component and pushes the limiting component to rotate and separate from the lever.
[0018] In the aforementioned clutch mechanism with a controllable normally open handle, the locking position includes a slot formed on the control panel, and the locking part includes a locking block fixed on the lever.
[0019] In the aforementioned clutch mechanism with a controllable normally open handle, a torsion spring is sleeved on the handle shaft, and two stops are provided on the panel, which are symmetrically arranged on the left and right sides of the handle shaft. The two ends of the torsion spring elastically abut against the two stops respectively. When the handle is rotated, one end of the torsion spring separates from the corresponding stop, and the other end overcomes the spring force and presses against the corresponding stop. After the handle is released, the torsion spring drives the handle shaft and the handle to reset.
[0020] In the aforementioned clutch mechanism with a controllable normally open handle, the limiting part includes a limiting pin fixed on the limiting member. When locked, the limiting pin elastically abuts against the side of the lever. After unlocking, the limiting member rotates upward, and the limiting pin moves above the lever to restrict the lever from resetting.
[0021] In the aforementioned clutch mechanism with a controllable normally open handle, the paddle is rotatably mounted inside the panel via a first rotating shaft, and the limiting member is rotatably mounted inside the panel via a second rotating shaft.
[0022] The second objective of this invention is to address the aforementioned problems of existing smart locks by proposing a smart lock panel with a clutch mechanism that allows the handle to be normally open.
[0023] The second objective of this utility model can be achieved through the following technical solution:
[0024] A smart lock panel includes an inner panel, an inner handle, an outer panel, an outer handle, and the aforementioned clutch mechanism. The inner handle is rotatably mounted on the inner panel, and the outer handle is rotatably mounted on the outer panel.
[0025] In the aforementioned smart lock panel, the outer handle is directly connected to the square steel on the lock body, and the two always rotate synchronously.
[0026] In the aforementioned smart lock panel, the outer panel is provided with a biometric module or electronic authorization module electrically connected to the aforementioned motor. The biometric module is a fingerprint recognition module or a face recognition module, and the electronic authorization module is a password module or a Bluetooth module, etc.
[0027] Compared with the prior art, the present invention has the following beneficial effects:
[0028] 1. After unlocking via fingerprint or password, the limiting component can prevent the lever from resetting and restrict the locking part from inserting into the locking position. The user can turn the handle an unlimited number of times from outside the door to open the door, thus keeping it in a constantly open state and making it more convenient to use.
[0029] 2. When locking is required, simply reverse the handle upwards. The guide post on the control panel will push the limit piece to rotate outwards and separate from the lever. After releasing the handle, the handle will automatically rotate downwards to reset, and the locking part will automatically insert into the locking position to achieve locking.
[0030] 3. After locking, because the locking part is inserted into the locking position, even if the outer panel of the door lock is forcibly removed, it cannot be unlocked by turning the square steel, so the anti-theft performance is good. Attached Figure Description

[0038] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0039] Example 1
[0040] This utility model discloses a clutch mechanism that controls the normally open handle 5, which is installed on a door lock panel 6. The handle 5 is rotatably mounted on the panel 6. The clutch mechanism includes a control plate 1, a lever 2, and a limiting member 3. The control plate 1 is fixedly connected to the handle 5. The lever 2 and the limiting member 3 are rotatably mounted on the panel 6. The lever 2 is rotatably mounted inside the panel via a first rotating shaft 19, and the limiting member 3 is rotatably mounted inside the panel via a second rotating shaft 20. The panel 6 is an inner panel, and the handle 5 is an inner handle. The inner panel is installed on the inside of the door.
[0041] like Figure 1 As shown, the control panel 1 has a locking position, and the lever 2 has a locking part that can cooperate with the locking position to lock the handle 5. The panel 6 has a driving component for driving the lever 2 to rotate, so that the locking part is disengaged from the locking position and the handle 5 is released from locking. The driving component is connected to a motor.
[0042] like Figure 2 As shown, the clutch mechanism also includes an elastic element one and an elastic element two. The elastic element one is used to drive the paddle 2 to rotate in the direction that makes the locking part cooperate with the locking position limit. The limiting element 3 is provided with a limiting part. When the locking part is out of the locking position, the elastic element two drives the limiting part to move to the rotation path of the paddle 2 to prevent the locking part from cooperating with the locking position limit, so as to keep the handle 5 in the normally open state.
[0043] like Figure 3 As shown, the control panel 1 is provided with a guide member. When the handle 5 is lifted, the guide member moves to abut against the limiting member 3 and pushes the limiting member 3 to rotate, so that the limiting part moves out of the rotation path of the lever 2. When the handle 5 rotates to reset, the locking part and the locking position can cooperate to lock the handle 5.
[0044] like Figure 3 and Figure 4 As shown, the control panel 1 has two mounting holes 12 for installing guide components. The panel 6 has a handle shaft 4 fixedly connected to the handle 5. The two mounting holes 12 are symmetrically arranged vertically relative to the handle shaft 4. The guide component is installed in one of the mounting holes 12, and the installation position of the guide component corresponds to the installation direction of the handle 5 on the outer side of the panel. The guide component includes a guide post 13 set on the control panel 1. When the handle 5 is reversed upwards, the outer wheel surface of the guide post 13 abuts against the limiting member 3 and pushes the limiting member 3 to rotate and separate from the lever 2. The installation position of the guide post 13 corresponds to the left-opening and right-opening states of the handle 5, respectively. When switching the opening direction of the handle 5, only the position of the guide post 13 needs to be changed.
[0045] like Figures 1 to 5 As shown, the locking position includes a slot 14 formed on the control plate 1, and the locking part includes a block 15 fixed on the lever 2. However, the structure of the locking position and the locking part of this utility model is not limited to this. It can also be a slot 14 formed on the lever 2 and a block 15 fixed on the control plate 1. Alternatively, the block 15 fixed on the lever 2 abuts against the control plate 1 to form a limit, or the block 15 fixed on the control plate 1 abuts against the lever 2 to form a limit. It is not limited to the structure of the block 15. It can also be other limiting structures such as a pin.
[0046] like Figures 1 to 5As shown, the limiting part includes a limiting pin 18 fixed on the limiting member 3. When locked, the limiting pin 18 elastically abuts against the side of the lever 2. After unlocking, the limiting member 3 rotates upward, and the limiting pin 18 moves above the lever 2 to restrict the lever 2 from resetting. However, the structure of the limiting part of this utility model is not limited to this. It can also be a baffle, a stop bar, or other limiting structures.
[0047] like Figures 1 to 4 As shown, the lever 2 is also provided with an extension, which passes through the panel 6 and extends out of the panel 6. The lever 2 is driven to rotate by moving the extension. When the user is inside the door, the lever 2 can be rotated by moving the extension to unlock the door. The extension includes a pull rod 8. A long groove 9 is provided on the panel 6. One end of the pull rod 8 is set on the lever 2, and the other end extends out of the long groove 9.
[0048] A torsion spring 16 is fitted onto the handle shaft 4. Two stops 17 are provided on the panel, symmetrically arranged on the left and right sides of the handle shaft 4. The two ends of the torsion spring 16 elastically abut against the two stops 17 respectively. When the handle 5 is rotated, one end of the torsion spring 16 separates from the corresponding stop 17, while the other end overcomes the spring force and presses against the corresponding stop 17. After the handle 5 is released, the torsion spring 16 drives the handle shaft 4 and the handle 5 to return to their original positions. The first and second elastic elements can be the torsion spring 16, or other elastic parts such as compression springs.
[0049] This utility model discloses a smart lock panel, comprising an inner panel, an inner handle, an outer panel, an outer handle, and the aforementioned clutch mechanism. The inner handle is rotatably mounted on the inner panel, and the outer handle is rotatably mounted on the outer panel. The outer handle is directly connected to a square steel bar on the lock body, and the two always rotate synchronously. The outer panel is equipped with a biometric module or an electronic authorization module electrically connected to the aforementioned motor. The biometric module is a fingerprint recognition module or a facial recognition module, and the electronic authorization module is a password module or a Bluetooth module, etc.
[0050] Example 2
[0051] like Figure 5 and Figure 6 As shown, the extension includes a pin 10, and an arc-shaped groove 11 is provided on the panel 6. One end of the pin 10 is set on the lever 2, and the other end extends out of the arc-shaped groove 11. When the lever 2 rotates back and forth, the pin 10 moves back and forth synchronously along the arc-shaped groove 11. When the lever 2 rotates back and forth, the arc-shaped groove 11 on the panel 6 can always be covered by the lever 2.
