Description

Technical Field

[0001] This invention relates to the field of lock technology, specifically to a door lock. Background Technology

[0002] A door lock is a device used to protect property, premises, or information security. The function of a lock is to provide a means of restricting and controlling access, ensuring that only authorized persons or individuals can use or enter the protected area or items. Locks can be used in various applications, such as home door locks, office door locks, vehicle locks, safe locks, computer combination locks, etc.

[0003] In the current technological landscape, smart locks are becoming an increasingly popular choice for homeowners. Smart locks utilize non-mechanical key unlocking methods such as fingerprints, Bluetooth, and passwords, offering significant convenience and a substantial improvement in security compared to traditional mechanical locks. However, when the lock experiences electronic malfunctions or low battery power, it may become inaccessible. While a spare mechanical key is typically used, users often don't carry it with them or leave it in an inconvenient location, preventing them from using it in an emergency. Summary of the Invention

[0004] In view of this, the present invention provides a door lock to solve the problem that users generally do not carry mechanical keys with them or leave mechanical keys in a spare location where they are inconvenient to retrieve, thus making it impossible for users to unlock the door in an emergency.

[0005] This invention provides a door lock, comprising:

[0006] case;

[0007] A lever, which is rotatably connected to one side of the housing;

[0008] The transmission structure is housed within the housing and located on one side of the paddle.

[0009] A drive mechanism is disposed within a housing and connected to a transmission structure or a paddle. The drive mechanism has a first state in which the transmission structure and the paddle are linked together, and a second state in which the linkage between the transmission structure and the paddle is released.

[0010] Multiple acquisition modules are housed within the casing;

[0011] The control structure, connected to the housing, is adapted to switch between multiple acquisition modules and the side of the transmission structure away from the paddle. The control structure is adapted to engage with the transmission structure when moved to the side of the transmission structure away from the paddle and be manipulated to drive the transmission structure to rotate.

[0012] The control module communicates with multiple acquisition modules and can control the drive mechanism to switch to the first state when the multiple acquisition modules acquire the control structure in a predetermined order.

[0013] Beneficial effects:

[0014] When the door lock of this invention experiences an electronic malfunction or insufficient power, the operator can drive the operating mechanism through multiple data acquisition modules in a predetermined sequence. This causes the control module to switch the drive mechanism to a first state and link the transmission structure with the paddle. The predetermined sequence can be entered by the user and pre-stored in the control module. Next, the operator can move the operating mechanism to the side of the transmission structure away from the paddle, enabling a transmission connection between the drive structure and the transmission structure. Rotating the operating mechanism causes the transmission structure to rotate, carrying the paddle, thus completing the emergency unlocking. This allows the operator to unlock the door in an emergency without carrying a mechanical key, improving the user experience.

[0015] When multiple acquisition modules fail to acquire the control structure in the predetermined order, the drive structure can switch the transmission structure to the second state and release the linkage between the transmission structure and the lever. At this time, even if the control structure is connected to the transmission structure and the control structure is rotated, the lever cannot be rotated. The operator can only unlock the door by moving the control structure in the preset order, thus ensuring the security of the door lock.

[0016] Furthermore, the door lock of the present invention can be unlocked by directly driving the lock body through a paddle, eliminating the need for components such as the lock body and lock cylinder, thereby reducing the manufacturing cost of the lock body.

[0017] In one alternative implementation, the control module includes a circuit board disposed within the housing, and the multiple acquisition modules include multiple spring switches disposed on the circuit board. The insertion end of the actuation structure is adapted to move on the side of the spring switch away from the circuit board to trigger the spring switch.

[0018] In one alternative implementation, the door lock is characterized by further comprising:

[0019] A guide plate, which is connected to the housing and is located on the side of the circuit board away from the lever, has multiple clearance openings formed on the guide plate. These clearance openings expose multiple spring switches and transmission structures respectively. The clearance openings are interconnected. The insertion end of the operating structure is adapted to pass through the clearance openings and move along the clearance openings.

[0020] Beneficial effects:

[0021] With this design, the sidewall of the clearance opening guides the control mechanism as the operator moves it, ensuring the operator accurately moves it to the corresponding spring switch. This facilitates use by the elderly or visually impaired. Furthermore, the combination of the control mechanism and the guide plate makes the user experience of this door lock similar to that of a tractor's gear shifter, conforming to user habits.

[0022] In one alternative embodiment, the door lock is characterized by further comprising an unlocking box disposed within and connected to the housing, a paddle passing through one side wall of the unlocking box, a transmission structure and a circuit board disposed within the unlocking box, and a guide plate on the side wall of the unlocking box away from the paddle.

[0023] In one alternative implementation, the door lock is characterized by further comprising:

[0024] The limiting sleeve is located inside the unlocking box and surrounds the transmission structure. The insertion end of the operating structure passes through the limiting sleeve and is connected to the transmission structure.

[0025] Beneficial effects:

[0026] In its initial state, the control structure can be inserted into the limiting sleeve, thus avoiding the control structure occupying too much space. When an unlocking operation is required, the operator can pull the control structure out of the limiting sleeve, so that the insertion end of the control structure moves between the circuit board and the guide plate, and drives the insertion end of the control structure to pass through multiple acquisition modules in sequence, and then return to the limiting sleeve, where it is connected to the transmission structure. Finally, the control structure is rotated within the limiting sleeve, so that the transmission structure drives the lever to unlock.

[0027] The limiting sleeve can both limit and guide the transmission and control structures, and can also be used to accommodate the insertion end of the control structure.

[0028] In one alternative embodiment, a first abutting protrusion is formed on the inner circumference of the limiting sleeve, and a second abutting protrusion is formed on the outer circumference of the transmission structure. The second abutting protrusion is located on the side of the first abutting protrusion away from the paddle, and a first elastic support is sandwiched between the first abutting protrusion and the second abutting protrusion.

[0029] Beneficial effects:

[0030] With this configuration, the first elastic support can drive the transmission structure to move away from the lever through its own elastic restoring force, thereby causing the transmission structure to abut against the operating structure and avoiding poor contact between the transmission structure and the operating structure, which would hinder the operator's unlocking operation. The first elastic support is preferably, but not limited to, a spring.

[0031] In one alternative embodiment, an anti-detachment edge is formed on the outer periphery of the insertion end of the operating structure, the anti-detachment edge being adapted to abut against the side of the guide plate that is close to the circuit board.

[0032] Beneficial effects:

[0033] With this design, the anti-detachment edge and the anti-detachment ring can work together to prevent the insertion end of the control structure from falling off through the clearance opening during the operator's movement of the control structure, thus improving the operator's user experience.

[0034] In one alternative embodiment, an abutment ring wall is formed on the insertion end of the operating structure, an anti-disengagement ring sleeve is fitted on the outer periphery of the operating structure, an anti-disengagement edge is formed on the outer periphery of the anti-disengagement ring sleeve, and a second elastic support member is sandwiched between the anti-disengagement edge and the abutment ring wall.

[0035] Beneficial effects:

[0036] When the operating structure is inside the limiting sleeve, the anti-detachment edge can abut against the guide plate under the support of the second elastic support member, and the anti-detachment ring can move towards the transmission structure under the support of the second elastic support member and abut against the transmission mechanism to avoid poor contact between the transmission structure and the operating structure, thus hindering the operator's unlocking operation.

[0037] When the operator pulls the operating mechanism out of the limiting sleeve and moves it between the circuit board and the guide plate, the abutment ring wall can press against the circuit board with the support of the second elastic element, ensuring that the operating mechanism can trigger the spring switch when passing by the spring switch. In addition, the operating mechanism can be hidden inside the lock through the second elastic structure, reducing the impact of the operating mechanism on the lock's appearance.

[0038] In one alternative embodiment, a partition plate is connected to the outer periphery of the limiting sleeve, the partition plate is located between the unlocking box and the circuit board, the spring switch passes through the partition plate, and the insertion end of the operating structure is adapted to move between the partition plate and the guide plate.

[0039] Beneficial effects:

[0040] The limiting sleeve can be connected to the unlocking box via a partition plate, thereby limiting the position of the limiting sleeve. Preferably, a connecting wall is also formed around the partition plate, one end of which is connected to the partition plate, and the other end abuts against the side of the unlocking box near the lever.

[0041] In one alternative embodiment, the door lock is characterized by further comprising a battery disposed on one side of the circuit board and electrically connected to the circuit board.

[0042] Beneficial effects:

[0043] The door lock of this invention uses a battery to independently power the control module, thereby ensuring that in the event of an electronic malfunction or insufficient battery power, the operator can use the control mechanism in conjunction with the circuit board for emergency unlocking. A button cell battery is preferred. Since the operation of driving the lever in this door lock is done manually by the operator, the power consumption during use is low. Furthermore, because the emergency unlocking mechanism is used infrequently, using a button cell battery to power the door lock ensures a service life of 5-10 years.

[0044] In one alternative embodiment, a shaped hole is formed on one of the operating structure and the transmission structure, and a transmission protrusion matching the shaped hole is formed on the other of the operating structure and the transmission structure.

[0045] Beneficial effects:

[0046] When the operating structure abuts against the transmission structure, the transmission protrusion can be inserted into the irregular hole, which allows the transmission structure to rotate along with the operating structure when the operating structure rotates under the action of external force.

[0047] In one alternative implementation, the door lock is characterized by further comprising:

[0048] The first mating part is located inside the housing and is connected to one end of the paddle near the transmission structure;

[0049] The second mating part is located on one side of the first mating part and is connected to the transmission structure. The drive mechanism is connected to the second mating part. In the first state, the power output end of the drive mechanism passes through the second mating part and the first mating part in sequence. In the second state, the power output end of the drive mechanism disengages from the first mating part.

[0050] Beneficial effects:

[0051] The first and second mating parts are respectively formed with a first through hole and a second through hole, which are interconnected. In the first state, the power output end of the drive mechanism passes through the second through hole and the first through hole in sequence. When the transmission structure is rotated by an external force, the paddle can rotate synchronously with the transmission structure. In the second state, the power output end of the drive mechanism is withdrawn from the first through hole. At this time, when the operator rotates the operating mechanism, the transmission mechanism will not drive the paddle to rotate. Attached Figure Description

[0072] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0073] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0074] According to an embodiment of the present invention, a door lock is provided, including a housing 1, a lever 2, a transmission structure 3, a drive mechanism 4, multiple acquisition modules 5, an operating structure 6, and a control module 7. The lever 2 is rotatably connected to one side of the housing 1. The transmission structure 3 is disposed within the housing 1 and located on one side of the lever 2. The drive mechanism 4 is disposed within the housing 1 and connected to either the transmission structure 3 or the lever 2. The drive mechanism 4 has a first state in which the transmission structure 3 and the lever 2 are linked, and a second state in which the linkage between the transmission structure 3 and the lever 2 is released. The multiple acquisition modules 5 are disposed within the housing 1. The operating structure 6 is connected to the housing 1 and is adapted to switch between the multiple acquisition modules 5 and the side of the transmission structure 3 away from the lever 2. The operating structure 6 is adapted to engage with the transmission structure 3 when moved to the side of the transmission structure 3 away from the lever 2 and be manipulated to drive the transmission structure 3 to rotate. The control module 7 is communicatively connected to the multiple acquisition modules 5 and is able to control the drive mechanism 4 to switch to the first state when the multiple acquisition modules 5 acquire data from the operating structure 6 in a predetermined sequence.

[0075] The door lock of this invention can respond to electronic malfunctions or insufficient power, such as... Figure 4 and Figure 5 As shown, the operator can drive the operating structure through multiple acquisition modules 5 in a predetermined order, so that the control module 7 controls the drive mechanism 4 to switch to the first state and links the transmission structure 3 with the lever 2. The predetermined order can be selected by the user and pre-stored in the control module 7. Then, as... Figure 2 and Figure 3As shown, the operator can move the control structure 6 to the side of the transmission structure 3 away from the paddle 2, so that the drive structure and the transmission structure 3 are connected, and rotate the control structure 6 to make the transmission structure carry the paddle 2 to rotate, thereby completing the emergency unlocking. This allows the operator to unlock in an emergency without having to carry a mechanical key, which can improve the user experience.

[0076] When multiple acquisition modules 5 fail to acquire the control structure 6 in the predetermined order, the drive structure can switch the transmission structure 3 to the second state and release the linkage between the transmission structure 3 and the lever 2. At this time, even if the control structure 6 is connected to the transmission structure 3 and the control structure 6 is rotated, the lever 2 cannot be rotated. The operator can only unlock the door by moving the control structure 6 in the preset order, thus ensuring the security of the door lock.

[0077] Furthermore, the door lock of the present invention can be directly driven to unlock the lock body by the lever 2, eliminating the need for components such as the lock body and lock cylinder, thereby reducing the manufacturing cost of the lock body.

[0078] In one embodiment, the control module 7 includes a circuit board disposed within the housing 1, and the plurality of acquisition modules 5 include a plurality of spring switches disposed on the circuit board. The actuating structure 6 is adapted to move on the side of the spring switches away from the circuit board to trigger the spring switches. The spring switches are preferably soldered to the circuit board.

[0079] As an alternative implementation, the acquisition module 5 may also be a sensor, such as a proximity switch, micro switch, or photoelectric sensor, which can detect the sensor when the operating structure 6 moves to the corresponding position of the sensor and send a signal to the control module 7.

[0080] The number of acquisition modules 5 is preferably, but not limited to, three, four, five, six, or more, for example, in... Figure 1 In the embodiment shown, the number of acquisition modules 5 is six, which can ensure that the password has sufficient complexity without excessively increasing the area occupied by the door lock.

[0081] In one embodiment, the door lock further includes a guide plate 801. The guide plate 801 is connected to the housing 1 and is disposed on the side of the circuit board away from the lever 2. A plurality of clearance openings 8011 are formed on the guide plate 801, which are adapted to expose a plurality of spring switches and clearance openings 8011 of the transmission structure 3, respectively. The plurality of clearance openings 8011 are interconnected, and one end of the operating structure 6 is adapted to pass through and move along the clearance openings 8011.

[0082] With this design, the side wall of the clearance opening 8011 guides the control structure 6 as the operator moves it, guiding the operator to accurately move the control structure 6 to the corresponding spring switch, thus facilitating use by the elderly or visually impaired. Simultaneously, the cooperation between the control structure 6 and the guide plate 801 makes the user experience of the door lock similar to that of a tractor gear shifter, conforming to user habits. The control structure 6 is preferably, but not limited to, a lever or wrench.

[0083] In one embodiment, the door lock further includes an unlocking box 8 disposed within and connected to the housing 1. A lever 2 passes through one side wall of the unlocking box 8, and a transmission structure 3 and a circuit board are disposed within the unlocking box 8. The side wall of the unlocking box 8 away from the lever 2 is a guide plate 801.

[0084] In one embodiment, the door lock further includes a limiting sleeve 901. The limiting sleeve 901 is disposed inside the unlocking box 8 and surrounds the transmission structure 3. One end of the operating structure 6 passes through the limiting sleeve 901 and is connected to the transmission structure 3 in a driving connection.

[0085] In the initial state, such as Figure 2 and Figure 3 As shown, the operating structure 6 can be inserted into the limiting sleeve 901, thus avoiding the operating structure 6 occupying too much space. When an unlocking operation is required, the operator can pull the operating structure 6 out of the limiting sleeve 901, so that the insertion end of the operating structure 6 moves between the circuit board and the guide plate 801 (see...). Figure 4 and Figure 5 ), and drive the insertion end of the manipulation structure 6 to pass sequentially through multiple acquisition modules 5 (see Figure 6 and Figure 7 Then, it returns to the limiting sleeve 901 and is connected to the transmission structure 3. Finally, the operating structure 6 is rotated in the limiting sleeve 901 so that the transmission structure 3 drives the paddle 2 to unlock.

[0086] The limiting sleeve 901 can limit and guide the transmission structure 3 and the operating structure 6, and can also be used to accommodate the insertion end of the operating structure 6.

[0087] In one embodiment, a first abutting protrusion 9011 is formed on the inner periphery of the limiting sleeve 901, and a second abutting protrusion 301 is formed on the outer periphery of the transmission structure 3. The second abutting protrusion 301 is located on the side of the first abutting protrusion 9011 away from the paddle 2, and a first elastic support member 11 is sandwiched between the first abutting protrusion 9011 and the second abutting protrusion 301.

[0088] With this configuration, the first elastic support 11 can drive the transmission structure 3 to move away from the lever 2 through its own elastic restoring force, thereby causing the transmission structure 3 to abut against the operating structure 6, avoiding poor contact between the transmission structure 3 and the operating structure 6, and preventing the operator from hindering the unlocking operation. The first elastic support 11 is preferably, but not limited to, a spring.

[0089] An abutment ring wall 601 is formed at the first end of the operating structure 6. An anti-detachment ring sleeve 602 is fitted on the outer periphery of the operating structure 6. An anti-detachment edge 6021 is formed on the outer periphery of the anti-detachment ring sleeve 602. The anti-detachment edge 6021 is adapted to abut against the side of the guide plate 801 that is close to the circuit board. A second elastic support member 12 is sandwiched between the anti-detachment edge 6021 and the abutment ring wall 601.

[0090] With this configuration, the anti-detachment edge 6021 and the anti-detachment ring 602 can cooperate with each other to prevent the insertion end of the control structure 6 from falling out through the clearance opening 8011 during the operator's movement of the control structure 6, thus improving the operator's user experience. When the control structure 6 is located within the limiting sleeve 901, the anti-detachment edge 6021 can abut against the guide plate 801 under the support of the second elastic support member 12, and the anti-detachment ring 602 can move towards the transmission structure 3 under the support of the second elastic support member 12 and abut against the transmission mechanism to prevent poor contact between the transmission structure 3 and the control structure 6, thus preventing the operator's unlocking operation from being hindered.

[0091] When the operator pulls the operating structure 6 out of the limiting sleeve 901 and moves it between the circuit board and the guide plate 801, the abutment ring wall 601 can press against the circuit board with the support of the second elastic element, ensuring that the operating structure 6 can trigger the spring switch when passing the spring switch. In addition, the operating structure 6 can be hidden inside the lock through the second elastic structure, reducing the impact of the operating structure 6 on the overall appearance of the lock.

[0092] In one embodiment, a partition plate 902 is connected to the outer periphery of the limiting sleeve 901. The partition plate 902 is located between the unlocking box 8 and the circuit board. The spring switch passes through the partition plate 902, and the end of the operating structure 6 is adapted to move between the partition plate 902 and the guide plate 801. The partition plate 902 can be used to abut against the insertion end of the operating structure 6, thereby protecting the circuit board and preventing the insertion end of the operating structure 6 from damaging the circuit board.

[0093] The limiting sleeve 901 can be connected to the unlocking box 8 through the partition plate 902, thereby achieving the limiting of the limiting sleeve 901. Preferably, a connecting wall is also formed around the partition plate 902, one end of the connecting wall is connected to the partition plate 902, and the other end abuts against the side of the unlocking box 8 near the lever 2.

[0094] In one embodiment, the door lock further includes a battery 10, which is disposed on one side of the circuit board and electrically connected to the circuit board. The door lock of the present invention independently powers the control module 7 via the battery 10, thereby ensuring that in the event of an electronic malfunction or insufficient power, the operator can use the operating structure 6 in conjunction with the circuit board for emergency unlocking. The battery 10 is preferably a button battery 10. Since the operation of rotating the drive lever 2 in this door lock is performed manually by the operator, the power consumption during use is low. Furthermore, because the emergency unlocking structure is used infrequently, using a button battery 10 to power the door lock ensures a service life of 5-10 years.

[0095] In one embodiment, a shaped hole 603 is formed on one of the operating structure 6 and the transmission structure 3, and a transmission protrusion 303 matching the shaped hole 603 is formed on the other of the operating structure 6 and the transmission structure 3. When the operating structure 6 and the transmission structure 3 abut against each other, the transmission protrusion 303 can be inserted into the shaped hole 603, so that when the operating structure 6 rotates under the action of an external force, the transmission structure 3 rotates with the operating structure 6.

[0096] The transmission protrusion 303 is preferably, but not limited to, a non-rotating structure such as a triangular prism, a quadrangular prism, a pentagonal prism, or a cross-shaped flower.

[0097] In one embodiment, the door lock further includes a first mating part 201 and a second mating part 302. The first mating part 201 is disposed within the housing 1 and connected to one end of the lever 2 near the transmission structure 3. The second mating part 302 is located on one side of the first mating part 201 and connected to the transmission structure 3. A drive mechanism 4 is connected to the second mating part 302. In a first state, the power output end of the drive mechanism 4 passes sequentially through the second mating part 302 and the first mating part 201. In a second state, the power output end of the drive mechanism 4 disengages from the first mating part 201.

[0098] The first mating part 201 and the second mating part 302 are, but are not limited to, mutually abutting disc structures. The first mating part 201 and the second mating part 302 are respectively formed with a first through hole and a second through hole, which are interconnected. In the first state, the power output end of the drive mechanism 4 passes through the second through hole and the first through hole in sequence. When the transmission structure 3 is rotated by an external force, the paddle 2 can rotate synchronously with the transmission structure 3. In the second state, the power output end of the drive mechanism 4 is withdrawn from the first through hole. At this time, when the operator rotates the operating mechanism, the transmission mechanism will not drive the paddle 2 to rotate.

[0099] As a variable implementation, the drive mechanism 4 is connected to the first mating part 201. In the first state, the power output end of the drive mechanism 4 passes sequentially through the first mating part 201 and the second mating part 302. In the second state, the power output end of the drive mechanism 4 is disengaged from the second mating part 302. The drive mechanism 4 can be a device capable of outputting linear motion, such as a hydraulic cylinder, pneumatic cylinder, electric cylinder, or a combination of a motor and a rack and pinion. Preferably, in this embodiment, the drive mechanism 4 is a push-pull electromagnet.

[0100] In addition, such as Figure 1 and Figure 2 As shown, the lock of the present invention also incorporates conventional smart lock unlocking modules such as the touch digital password module 14, the face recognition unlocking module 13, and the fingerprint unlocking module 15, which are well known to those skilled in the art and will not be described in detail here.

[0101] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
