Description

Technical Field

[0001] This manual relates to the technical field of locks, and in particular to a semi-automatic smart door lock. Background Technology

[0002] Door locks, such as semi-automatic smart locks, involve electronic identification technology and a mechanical lock cylinder controlled by a motor. They improve the convenience and efficiency of opening, closing, and locking, while providing traceability and security in terms of door lock alarms and security records. Semi-automatic smart locks can be configured in a normally open mode. In this mode, the lock remains unlocked; simply pressing down on either the front or rear door handle completes the unlocking process. Users can activate the normally open mode by operating the control panel on the outer door handle or through a mobile app. Users can also deactivate the normally open mode through the app; however, activating and deactivating this mode is relatively complex.

Detailed Implementation

[0030] To more clearly illustrate the technical solutions of the embodiments in this specification, the embodiments will be described in detail below with reference to the accompanying drawings. Obviously, the content described below are some examples or embodiments of this specification. For those skilled in the art, without creative effort, the technical solutions or means disclosed in this specification can be applied to other scenarios based on this technical content.

[0031] It should be understood that the terms "system," "device," "equipment," "part" and / or "component," "unit" and / or "module" used in this specification are a method of distinguishing different components, elements, parts, sections, or assemblies at different levels. However, if other words can achieve the same purpose, they may be replaced by other expressions.

[0032] Unless otherwise specified, the technical terms used to describe components, elements, etc. in this specification are not singular but may include plural. Generally speaking, terms such as "comprising" or "including" only indicate that explicitly identified steps, elements, or components are included, and these steps, elements, and components do not constitute an exclusive list, as the described method or apparatus may also include other steps or components.

[0033] In the description of this specification, it should be understood that the directional descriptions, such as up, down, front, back, left, and right, indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. These descriptions are for the convenience of describing this application and for simplification, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In the description of this specification, unless otherwise expressly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly. Those skilled in the art can reasonably determine the specific meaning of the above terms in this specification in conjunction with the specific content of the technical solution.

[0034] Door locks, such as semi-automatic smart door locks, involve electronic identification technology and mechanical lock cylinders controlled by motors. They can improve the convenience and efficiency of opening, closing and locking the door, while providing traceability and security in terms of door lock alarms and security records.

[0035] In some use cases, the workflow of a semi-automatic smart door lock may include a user authentication stage, a successful authentication stage, and an unlocking stage. The user authentication stage may involve verifying the user's identity via fingerprint, password, card swipe, Bluetooth, etc. The successful authentication stage may involve configuring the semi-automatic smart door lock into an unlocked state after successful user authentication, linking the front door handle with the square steel bar to allow the user to operate the lock cylinder mechanism via the front door handle. The unlocking stage may involve the user pressing down on the front door handle to rotate the square steel bar and retract the bolt, completing the pressing-to-unlock process while the semi-automatic smart door lock is in the unlocked state. In some use cases, the workflow of a semi-automatic smart door lock may also include a locking stage. The locking stage may involve delaying for a preset time after completing the pressing-to-unlock process, configuring the semi-automatic smart door lock into a locked state, deactivating the front door handle from the square steel bar, and preventing other users from operating the lock cylinder mechanism via the front door handle.

[0036] In some public usage scenarios, such as dormitories and public offices where the number of people entering is not fixed, semi-automatic smart door locks cannot grant access to just anyone, yet there is a need to allow unrestricted entry. Simultaneously, there is a need to lock the door after everyone has left to prevent unauthorized personnel from entering (e.g., locking the door of a public office after get off work, or locking the door of a dormitory at night). Therefore, in some related embodiments, semi-automatic smart door locks can be configured in a normally open mode. In normally open mode, the semi-automatic smart door lock remains unlocked; that is, simply pressing down on the front or back door handle completes the unlocking process.

[0037] In some related embodiments, users can open the semi-automatic smart lock's always-open mode by operating the control panel on the outer door handle or by operating the terminal app. In some related embodiments, users can close the semi-automatic smart lock's always-open mode by operating the terminal app; however, the method of opening and closing this always-open mode is relatively complex.

[0038] Based on this, one or more embodiments of this specification provide a semi-automatic smart door lock with a normally open mode function, which can be opened in normally open mode by pressing down the inner door handle.

[0039] Figure 1 This is an exploded view of a semi-automatic smart door lock with a normally open mode function, as shown in some embodiments of this specification. Figure 2 This is an exploded view of the front door handle mechanism of a semi-automatic smart door lock with a normally open mode, as shown in some embodiments of this specification. Figure 3 This is an exploded view of the rear door handle mechanism of a semi-automatic smart door lock with a normally open mode, as shown in some embodiments of this specification. See also... Figures 1 to 3 As shown, in one or more embodiments of this specification, a semi-automatic smart door lock with a normally open mode function may include: a lock cylinder mechanism 1, a square steel 2 passing through the lock cylinder mechanism 1, a front door handle mechanism, and a rear door handle mechanism. In some embodiments, the door lock may be installed on the door body. In some embodiments, the lock cylinder mechanism 1 may include a bolt for locking the door body. In some embodiments, the bolt may include a beveled bolt and a square bolt. In some embodiments, the beveled bolt may automatically extend and retract by arranging elastic components such as springs, popping out to lock into the door frame lock slot when the door is closed to complete basic locking, and retracting by pressing the front or rear door handle when the door is opened. In some embodiments, the square bolt may not be provided with elastic components such as springs, and may extend and retract manually or by a motor to resist violent intrusion methods such as card picking.

[0040] In some embodiments, the front door handle mechanism and the rear door handle mechanism are used to operate the lock cylinder mechanism 1 from the outside and inside of the door, respectively, to realize the function of the door lock. In some embodiments, the front door handle mechanism may be a door handle mechanism located on the outside of the door. In some embodiments, the rear door handle mechanism may be a door handle mechanism located on the inside of the door. In some embodiments, the front door handle mechanism may include a front door handle 4. In some embodiments, the rear door handle mechanism may include a rear door handle 3.

[0041] In some usage scenarios, the door lock can be in the unlocked state. In some embodiments, when the door lock is in the unlocked state, the angled bolt can be extended and the square bolt can be retracted. In some embodiments, when the door lock is in the unlocked state, the user can open the door lock by pressing down the front door handle 4 or the rear door handle 3, for example, by pressing down the front door handle 4 or the rear door handle 3 to retract the angled bolt to open the door lock.

[0042] In some usage scenarios, the door lock can be in the locked state. In some embodiments, when the door lock is in the locked state, both the angled latch and the square latch can be extended. In some embodiments, when the door lock is in the locked state, the user cannot press down the front door handle 4 to open the door lock. In some embodiments, when the door lock is in the unlocked state, the user can adjust the door lock to the locked state by raising the front door handle 4 or raising the rear door handle 3.

[0043] In some embodiments, the front door handle 4 can be drivenly connected to the square steel 2. In some embodiments, the front door handle 4 can be connected to the square steel 2 via a clutch 41. In some embodiments, the clutch 41 can drive the front door handle 4 to the square steel 2 or disengage the front door handle 4 from the square steel 2. In some embodiments, the rear door handle 3 can be drivenly connected to the square steel 2. In some embodiments, the square steel 2 can pass through the lock cylinder mechanism 1, and the rotation of the square steel 2 controls the oblique locking tongue and the square locking tongue of the lock cylinder mechanism 1.

[0044] It should be noted that "square steel" is a common name for a component used as a transmission element in locks, such as door locks. In one or more embodiments of this specification, the use of "square steel" as the name of the component is for ease of understanding only and is not intended to limit the shape and / or material of the component. In some embodiments, square steel 2 is a transmission element used to transmit the power provided by the front door handle 4 and the rear door handle 3 to the lock cylinder mechanism 1, so as to facilitate the operation of the lock cylinder mechanism 1 by the front door handle 4 or the rear door handle 3. In some embodiments, square steel 2 may be in the form of a strip. In some embodiments, one end of square steel 2 may be connected to the front door handle 4, and the other end of square steel 2 may pass through the lock cylinder mechanism 1 and be connected to the rear door handle 3. In some embodiments, the cross-section of square steel 2 may be rectangular. In other embodiments, the cross-section of square steel 2 may also be other shapes, such as other non-circular shapes, such as polygons, ellipses, etc. In some embodiments, the cross-sectional shape of square steel 2 may be the same or different at various points in the axial direction.

[0045] In one or more embodiments of this specification, see Figures 4 to 7 As shown, the rear door handle mechanism may include a stop position rotating shaft 5, which is mounted on the square steel 2 and configured to rotate synchronously with the square steel 2. In some embodiments, configuring the stop position rotating shaft 5 to rotate synchronously with the square steel 2 may include the stop position rotating shaft 5 rotating with the square steel 2 and having the same rotation angle as the square steel 2. In some embodiments, the rear door handle 3 may be fixedly connected to the square steel 2, and the stop position rotating shaft 5 may rotate with the rear door handle 3 and have the same rotation angle as the rear door handle 3.

[0046] For example, the stop position pivot 5 may have a through hole through which the square steel 2 passes. In some embodiments, the shape of the through hole matches the shape of the square steel 2, thereby allowing the stop position pivot 5 to rotate with the square steel 2 when the square steel 2 rotates.

[0047] In one or more embodiments of this specification, see Figures 7 to 12 As shown, the stop position pivot 5 includes a pressing action protrusion 51. In some embodiments, a semi-automatic smart door lock with a normally open mode function may further include a pressing action sensor 6 that matches the stop position pivot 5. The pressing action sensor 6 may include a pressing action sensing structure 61 that can swing relative to a first rotation axis.

[0048] In some embodiments, the pressure action sensing structure 61 can control the on / off state of the circuit of the pressure action sensor 6 by swinging around the first rotation axis, thereby realizing the position sensing of the stop position pivot 5, and further realizing the position sensing of the front door handle 4 or the rear door handle 3.

[0049] In some embodiments, when the pressure action sensing structure 61 is in its initial position, the circuit of the pressure action sensor 6 may be open. In some embodiments, when the pressure action sensing structure 61 oscillates about a first rotation axis, the circuit of the pressure action sensor 6 may be closed to provide a first sensing signal.

[0050] In some embodiments, the pressure-sensing structure 61 can rotate about a first rotation axis, such that a portion of the pressure-sensing structure 61 forms an oscillation relative to the first rotation axis. See, for example... Figure 11 As shown, the pressing motion sensing structure 61 can be triangular in shape, and the pressing motion sensing structure 61 can rotate around the first rotation axis L1 so that the upper end of the pressing motion sensing structure 61 swings relative to the first rotation axis L1.

[0051] In some embodiments, the pressing action protrusion 51 is configured to abut against the pressing action sensing structure 61 and cause the pressing action sensing structure 61 to rotate, or to disengage from the pressing action sensing structure 61 and cause the pressing action sensing structure 61 to return to its original position.

[0052] In one or more embodiments of this specification, the door lock may have a normally open mode. In some embodiments, when the normally open mode of the door lock is activated, the door lock remains in the unlocked state. In some embodiments, when the normally open mode of the door lock is activated, the front door handle 4 can be drivenly connected to the square steel 2 via the clutch 41, and the rear door handle 3 can be drivenly connected to the square steel 2. In some embodiments, when the normally open mode of the door lock is activated, the user can open the door lock by pressing down the front door handle 4 (e.g., causing the latch to retract), or by pressing down the rear door handle 3.

[0053] In some embodiments, when the normally open mode of the door lock is closed, the door lock may be in a locked state, or the door lock may enter a locked state after a preset time following its unlocked state. In some embodiments, when the normally open mode of the door lock is closed, the front door handle 4 is configured to disengage from the square steel 2, while the rear door handle 3 may be connected to the square steel 2. In some embodiments, when the normally open mode of the door lock is closed, the user cannot open the door lock by pressing down the front door handle 4, but can open the door lock by pressing down the rear door handle 3. In some embodiments, when the normally open mode of the door lock is closed, and the user is outside the door, the user can open the door lock through user authentication, such as by fingerprint, password, card swipe, Bluetooth, etc., or by using a key.

[0054] In one or more embodiments of this specification, the pressure action sensor 6 is configured to provide a normally open mode activation signal (e.g., the aforementioned first sensing signal) based on the rotation of the pressure action sensing structure 61 (e.g., the oscillation of the pressure action sensing structure 61 about the first rotation axis L1). In some embodiments, the semi-automatic smart door lock with normally open mode functionality may further include a main control unit 100, which is signal-connected to the clutch 41.

[0055] In some embodiments, the main control unit 100 is configured to provide instructions to the clutch 41 based on a normally open mode opening signal so that the front door handle 4 and the square steel 2 are connected in the downward rotation direction, so that the downward rotation of the front door handle 4 can be transmitted to the square steel 2 in the normally open mode, thereby allowing the user to open the door lock by pressing down the front door handle 4 in the normally open mode.

[0056] In some embodiments, the main control unit 100 is configured to provide instructions to the clutch 41 based on a normally open mode opening signal, so that the front door handle 4 and the square steel 2 are connected in both the downward rotation direction and the upward rotation direction, so that in the normally open mode, both the downward rotation and the upward rotation of the front door handle 4 can be transmitted to the square steel 2, thereby allowing the user to open the door lock by pressing down the front door handle 4 in the normally open mode, and at the same time allowing the user to lock the door by pressing up the front door handle 4 (e.g., causing the square lock tongue to extend).

[0057] In one or more embodiments of this specification, see Figures 7 to 12 As shown, the stop position pivot 5 includes an upward action protrusion 52. In some embodiments, a semi-automatic smart door lock with a normally open mode function may also include an upward action sensor 7 that matches the stop position pivot 5. The upward action sensor 7 may include an upward action sensing structure 71 that can swing relative to a second rotation axis.

[0058] In some embodiments, the lifting motion sensing structure 71 can control the on / off state of the circuit of the lifting motion sensor 7 by swinging around the second rotation axis, thereby realizing the position sensing of the stop position pivot 5, and further realizing the position sensing of the front door handle 4 or the rear door handle 3.

[0059] In some embodiments, when the lifting motion sensing structure 71 is in its initial position, the circuit of the lifting motion sensor 7 may be open. In some embodiments, when the lifting motion sensing structure 71 swings about the second rotation axis, the circuit of the lifting motion sensor 7 may be closed to provide a second sensing signal.

[0060] In some embodiments, the lifting motion sensing structure 71 may rotate about a second rotation axis, such that a portion of the lifting motion sensing structure 71 forms an oscillation relative to the second rotation axis. See, for example... Figure 11 As shown, the lifting motion sensing structure 71 can be in the shape of an inverted triangle, and the lifting motion sensing structure 71 can rotate around the second rotation axis L2 so that the lower end of the lifting motion sensing structure 71 swings relative to the second rotation axis L2.

[0061] In some embodiments, the lifting action protrusion 52 is configured to abut against the lifting action sensing structure 71 and cause the lifting action sensing structure 71 to rotate, or to disengage from the lifting action sensing structure 71 and cause the lifting action sensing structure 71 to return to its original position.

[0062] In one or more embodiments of this specification, the lifting motion sensor 7 is configured to provide a normally open mode closing signal (e.g., the aforementioned second sensing signal) based on the rotation of the lifting motion sensing structure 71 (e.g., the oscillation of the lifting motion sensing structure 71 about the second rotation axis L2).

[0063] In some embodiments, the main control unit 100 is configured to provide instructions to the clutch 41 based on the normally open mode closing signal to disengage the front door handle 4 and the square steel 2 in the downward rotation direction (or to disengage the front door handle 4 and the square steel 2 in both the downward rotation direction and the upward rotation direction), so as to prevent the downward rotation of the front door handle 4 from being transmitted to the square steel 2 in the normally open mode closed, thereby preventing the user from opening the door lock by pressing down the front door handle in the normally open mode closed (e.g., when the door lock is in the locked state after the normally open mode is closed).

[0064] In some embodiments, the main control unit 100 is configured to provide instructions to the clutch 41 based on a normally open mode closing signal to disengage the front door handle 4 and the square steel 2 in the downward rotation direction (or in both the downward rotation direction and the upward rotation direction) so as to prevent the downward rotation of the front door handle 4 from being transmitted to the square steel 2 when the normally open mode is closed (e.g., when the door lock is in the locked state after the normally open mode is closed), thereby preventing the user from opening the door lock by pressing down the front door handle 4 when the normally open mode is closed.

[0065] In one or more embodiments of this specification, in some usage scenarios, a user can press down on the rear door handle 3 to cause the square steel 2 to rotate downwards, thereby operating the lock cylinder mechanism 1 (e.g., retracting the oblique bolt or retracting both the oblique bolt and the square bolt) while simultaneously driving the stop position rotating shaft 5 to rotate downwards. At this time, the downward pressing action protrusion 51 of the stop position rotating shaft 5 rotates, abuts against the downward pressing action sensing structure 61, and further causes the downward pressing action sensing structure 61 to swing around the first rotation axis L1, thereby putting the downward pressing action sensor 6 in the path to provide a normally open mode opening signal. After receiving the normally open mode opening signal, the main control unit 100 provides a command to the clutch 41, and the clutch 41 operates to drive the front door handle 4 and the square steel 2. At this time, the normally open mode is activated, and any user can open the door lock by pressing down on the front door handle 4 or the rear door handle 3, thereby allowing any user to enter freely.

[0066] In some usage scenarios, users can lift the rear door handle 3 or the front door handle 4 to rotate the square steel 2, thereby operating the lock cylinder mechanism 1 (e.g., extending the oblique bolt or both the oblique bolt and the square bolt) while simultaneously rotating the stop position pivot 5. At this time, the lifting action protrusion 52 of the stop position pivot 5 rotates, abuts against the lifting action sensing structure 71, and further causes the lifting action sensing structure 71 to swing around the second rotation axis L2, thus placing the lifting action sensor 7 in the path to provide a normally open mode closing signal. Upon receiving the normally open mode closing signal, the main control unit 100 sends a command to the clutch 41, which operates to disengage the front door handle 4 and the square steel 2 from the transmission. At this time, the normally open mode is closed, and users cannot open the door lock by pressing down the front door handle 4, thus prohibiting unauthorized users from entering and allowing specific users to enter through user authentication or a key.

[0067] In summary, in some usage scenarios, users can open the normally open mode by pressing down the rear door handle 3. When the normally open mode is open, users can unlock the door by pressing down either the front door handle 4 or the rear door handle 3. In some usage scenarios, users can lock the door from the inside and close the normally open mode by lifting the rear door handle 3. In some usage scenarios, users can lock the door from the outside and close the normally open mode by lifting the front door handle 4. When the normally open mode is closed, users cannot unlock the door by pressing down the front door handle 4, but can unlock the door through user authentication or a key. In some usage scenarios, when the normally open mode is closed, users can lift the rear door handle 3 or the front door handle 4 to trigger the lifting motion sensor 7 to provide a signal confirming the normally open mode is closed again.

[0068] In one or more embodiments of this specification, the stop position pivot 5 has a disc-shaped structure. In some embodiments, one side of the lower portion of the stop position pivot 5 protrudes outward to form a pressing action protrusion 51, and a pressing action sensor 6 is disposed below the stop position pivot 5. In this embodiment, one side of the upper portion of the stop position pivot 5 protrudes outward to form a lifting action protrusion 52, and a lifting action sensor 7 is disposed above the stop position pivot 5. In some embodiments, in the natural state, the projections of the pressing action protrusion 51 and the lifting action protrusion 52 on the horizontal plane are located on the same side of the stop position pivot 5. For example, see Figure 6 As shown, in the natural state, the projections of the downward pressing protrusion 51 and the upward lifting protrusion 52 on the horizontal plane are both located to the left of the stop position pivot 5 (e.g., Figure 8 (To the left of the dashed line). In some embodiments, the natural state may refer to the state in which the user does not operate the front door handle 4 or the rear door handle 3. In some embodiments, the natural state may refer to the initial state or the unrotated state of the stop position pivot 5.

[0069] In other embodiments, one side of the upper portion of the stop position pivot protrudes outward to form a pressing action protrusion, and a pressing action sensor is located above the stop position pivot. In this embodiment, one side of the lower portion of the stop position pivot protrudes outward to form a lifting action protrusion, and a lifting action sensor is located below the stop position pivot. In this embodiment, in the natural state, the projections of the pressing action protrusion and the lifting action protrusion onto the horizontal plane are also located on the same side of the stop position pivot.

[0070] In some embodiments, the pressing and lifting protrusions can be respectively located on the left and right sides of the upper part of the stop position pivot, or respectively located on the left and right sides of the lower part of the stop position pivot. The pressing and lifting sensors are respectively located close to the pressing and lifting protrusions. In this embodiment, in the natural state, the projections of the pressing and lifting protrusions on the vertical plane are located on the same side of the stop position pivot (e.g., both located on the upper side of the stop position pivot, or both located on the lower side of the stop position pivot).

[0071] In one or more embodiments of this specification, the pressure sensor 6 and the lifting sensor 7 may be arranged on the upper and lower sides of the stop position pivot 5 to allow the pressure sensor 6 and the lifting sensor 7 to be routed above or below the door lock and to adapt to the spatial arrangement of the door lock (the door lock is usually wider in the downward direction and narrower in the left and right direction).

[0072] In one or more embodiments of this specification, the pressing action protrusion 51 includes a pressing concave arc surface 511 for avoiding the pressing action sensing structure 61 and a pressing convex arc surface 512 capable of abutting against the pressing action sensing structure 61, wherein the pressing concave arc surface 511 and the pressing convex arc surface 512 are connected. In some embodiments, the pressing concave arc surface 511 and the pressing convex arc surface 512 form an S-shaped structure so that when the pressing convex arc surface 512 abuts against the pressing action sensing structure 61, the pressing concave arc surface 511 will not interfere with the swing of the pressing action sensing structure 61.

[0073] In some embodiments, the side of the downward concave arc surface 511 away from the downward convex arc surface 512 is provided with a downward pressure avoidance notch 513 for avoiding the downward pressure action sensing structure 61 in the non-rotated state.

[0074] In one or more embodiments of this specification, the lifting action protrusion 52 includes a lifting concave arc surface 521 for avoiding the lifting action sensing structure 71 and a lifting convex arc surface 522 capable of abutting against the lifting action sensing structure 71, wherein the lifting concave arc surface 521 and the lifting convex arc surface 522 are connected. In some embodiments, the lifting concave arc surface 521 and the lifting convex arc surface 522 form an S-shaped structure so that when the lifting convex arc surface 522 abuts against the lifting action sensing structure 71, the lifting concave arc surface 521 will not interfere with the swing of the lifting action sensing structure 71.

[0075] In some embodiments, the side of the upward concave arc surface 521 away from the upward convex arc surface 522 is provided with an upward avoidance notch 523 for avoiding the upward motion sensing structure 71 in the non-rotated state.

[0076] In one or more embodiments of this specification, see Figure 7 , Figure 8 As shown, the stop position pivot 5 includes a rotation limit part 53, which is located between the pressing action protrusion 51 and the lifting action protrusion 52.

[0077] In some embodiments, the rotation limiting portion 53 may protrude from the stop position pivot 5 along the axial direction of the stop position pivot 5. In some embodiments, the rear door handle mechanism may include an upward rotation limiting protrusion 54. In some embodiments, when the stop position pivot 5 is rotated upward, the rotation limiting portion 53 (e.g., the upper surface of the rotation limiting portion 53) may abut against the upward rotation limiting protrusion 54 to limit the angle of upward rotation. In some embodiments, the rear door handle mechanism may include a downward rotation limiting protrusion. In some embodiments, when the stop position pivot 5 is rotated downward, the rotation limiting portion 53 (e.g., the lower surface of the rotation limiting portion 53) may abut against the downward rotation limiting protrusion to limit the angle of downward rotation.

[0078] In some embodiments, the rotation limit part 53 may be formed by bending the plate of the stop pivot 5.

[0079] In one or more embodiments of this specification, see Figure 13 As shown, a semi-automatic smart door lock with a normally open mode function may further include: an authentication unit 200, which is signal-connected to the main control unit 100. In some embodiments, the authentication unit 200 may be used to perform user authentication, such as through fingerprint, password, card swipe, Bluetooth, etc.

[0080] In one or more embodiments of this specification, see Figure 13 As shown, a semi-automatic smart door lock with a normally open mode function may further include a speaker 300, which is signal-connected to the main control unit 100. In some embodiments, the speaker 300 may be used to announce the status of the door lock, such as announcing "normally open mode open" and / or "normally open mode closed".

[0081] The beneficial effects that the embodiments of this specification may bring include, but are not limited to: (1) the normal open mode can be opened at the same time as the lock cylinder mechanism is operated by pressing down the rear door handle; (2) the pressing action sensor's pressing action sensing structure detects the pressing rotation of the stop position shaft driven by the pressing rotation of the rear door handle, thereby providing a signal for the normal open mode to be opened; (3) the transmission connection or disengagement between the front door handle and the square steel is realized by the clutch, so as to adapt to the control requirements of the front door handle in different states such as normal open mode opening or normal open mode closing; (4) the front door handle is opened by lifting up or the rear door handle is opened by lifting up. The door handle can be closed in the normally open mode while locking the lock cylinder mechanism; (5) The lifting action sensor and the pressing action sensor are set on the upper and lower sides of the stop position pivot to adapt to the arrangement requirements of the door lock having a large space in the vertical direction and a small space in the horizontal direction; (6) The cooperation between the pressing convex arc surface and the pressing concave arc surface, and the cooperation between the lifting convex arc surface and the lifting concave arc surface, allow the stop position pivot to drive the pressing action sensor or the lifting action sensor without structural interference; (7) The rotation action limit part can limit the angle of the pressing rotation of the stop position pivot and / or the angle of the lifting rotation. It should be noted that different embodiments may produce different beneficial effects. In different embodiments, the beneficial effects that may be produced can be any one or a combination of the above, or any other possible beneficial effects.
