Description

Technical Field

[0001] This utility model belongs to the field of door lock technology, and in particular relates to a lock. Background Technology

[0002] Locks are devices that serve a sealing function. They include locks, keys, and their accessories. Existing locks generally have automatic unlocking and manual key unlocking functions.

[0003] Existing technology, such as CN114658294B, utilizes a linkage component to cause the first actuating block to slide the latch; similarly, existing technology, such as CN203175173U, uses a slanted latch guide clutch connected to an inner and outer linkage plate to transmit power. It is evident that the first actuating block and the slanted latch guide clutch in these existing technologies are irregularly shaped parts, which are not only disadvantageous for production but also result in higher processing costs. In particular, the existing technologies employ a large number of components and have a complex structure to achieve the sliding of the latch within the housing, leading not only to congestion within the housing but also to increased production costs. Summary of the Invention

[0004] The purpose of this utility model is to overcome the defects of the prior art by providing a lock that solves the problem of a large number of parts used when the lock tongue slides inside the lock, resulting in crowded internal space and high production costs.

[0005] The technical solution of this utility model is as follows: A lock includes a lock body and a magnetic latch that extends and retracts into and out of the lock body. The lock body is provided with a driving component and a toggle component. The magnetic latch extends between the driving component and the toggle component. The driving component and the magnetic latch are connected by a transmission component.

[0006] The transmission component rotates on the lock body after being driven by the driving component. The transmission component and the actuating component rotate independently. After the actuating component or the transmission component rotates, it independently pushes the magnetic latch to move within the lock body.

[0007] The lock body is also provided with a control unit for controlling the operation of the drive components. The control unit includes a battery box that supplies power to the lock. The battery box is detachably installed in the lock body. The battery box is inserted and removed along the extension and retraction direction of the magnetic latch, and the insertion and removal interface is located on the same side end face of the lock body where the magnetic latch enters and exits.

[0008] By adopting the above technical solution, the lock body integrates a drive component, actuating component, and transmission component in a coordinated design. The transmission component and actuating component rotate independently, allowing the transmission component to cause the magnetic latch to slide, and the actuating component to cause the latch to slide independently. In practical use, the lock can be unlocked by inserting an external key to drive the actuating component to rotate, or the lock can be unlocked automatically by driving the transmission component to rotate. This achieves both automatic and manual dual-drive modes for the magnetic latch, providing strong flexibility. The overall design has fewer parts and a simplified structure, saving lock body space. Furthermore, the battery box is inserted and removed along the extension and retraction direction of the latch, and the interface is on the same end face of the lock body as the magnetic latch. Therefore, when the door is closed, the battery box is located inside the door body, making it less likely for the battery box or even the batteries inside to come out even under strong shaking. This also prevents accidental disassembly by children, thus ensuring reliable power supply to the lock body from the battery box.

[0009] A further feature of this invention is that the actuating element is rotatably engaged with the lock body, the transmission element is sleeved on the outside of the actuating element, and the transmission element and the actuating element are rotatably arranged relative to each other.

[0010] By adopting the above-mentioned further configuration, a layered coaxial structure with an embedded toggle component and an outer sleeve for the transmission component is used to optimize space utilization, avoid motion interference, and ensure that manual and automatic operations are independent of each other, resulting in overall reliability.

[0011] A further feature of this invention is that both ends of the actuating member are provided with first shoulders for contacting the upper and lower end faces of the lock body cavity, respectively, and the inner cylindrical surface of the first shoulder fits into the openings provided on the upper and lower end faces of the lock body.

[0012] The transmission component is sleeved on the outer cylindrical surface of the first shoulder and is rotatably disposed relative to it. A second shoulder is also disposed between the two first shoulders. The transmission component is constrained between the second shoulder and the end face of the inner cavity of the lock body.

[0013] With the above-mentioned further configuration, the contact between the first shoulder and the end face of the lock body is used to achieve precise axial positioning of the actuating component, and the inner cylindrical surface of the first shoulder fits into the opening of the housing to achieve radial support. The second shoulder limits the axial displacement of the transmission component, thereby effectively preventing the movement of parts and making the transmission more stable.

[0014] A further feature of this invention is that the transmission component includes an arc-shaped rack, the output end of the drive component meshes with the arc-shaped rack, and the transmission component and the magnetic locking tongue are provided with a slotted-post engagement structure. After the transmission component rotates, it drives the magnetic locking tongue to move through the slotted-post engagement structure.

[0015] With the above-mentioned further configuration, the arc-shaped rack meshes with the output end of the drive component, and provides direct mechanical driving force through the slotted column mating structure, which efficiently converts the rotational motion into the linear extension and retraction action of the magnetic locking tongue. The transmission path is simple and reliable, with fast response speed and low energy consumption.

[0016] A further feature of this invention is that the groove-column mating structure includes a protrusion on the transmission component and a groove on the magnetic locking tongue. The transmission component abuts against the front or rear face of the groove through the protrusion to drive the magnetic locking tongue.

[0017] With the above-mentioned further design, the selective contact design between the protrusion and the front and rear end faces of the groove allows the transmission component to push the magnetic latch to retract into the lock body in one direction. It can also reset the transmission component when the magnetic latch extends under the action of magnetic force, thus realizing the automatic unlocking drive mode.

[0018] A further feature of this invention is that the groove-column mating structure includes an arc-shaped groove on the transmission component and a protrusion on the magnetic locking tongue. The transmission component abuts against the protrusion through the wall of the arc-shaped groove to drive the magnetic locking tongue.

[0019] With the above-mentioned further configuration, the combination of the arc-shaped groove and the protrusion transmits the thrust through the groove wall. The arc-shaped trajectory matches the rotational motion characteristics, making the thrust on the magnetic latch smooth. Moreover, both sides of the arc-shaped groove have side walls, which allows the transmission component to push the magnetic latch back into the lock body in one direction. It can also reset the transmission component when the magnetic latch extends under the action of magnetic force, realizing the automatic unlocking drive mode.

[0020] A further feature of this invention is that the actuating element contacts a protrusion on the magnetic latch via a toggle block, thereby actuating the magnetic latch. A return spring is provided on one side of the actuating element, with its two ends connected to the actuating element and the lock body, respectively. The return spring is used to ensure that the actuating element returns to its original position when no external force is applied.

[0021] With the above-mentioned further settings, the reset spring automatically returns to the toggle mechanism, ensuring that the lock returns to standby mode after the key is removed, avoiding accidental operation. The two ends of the reset spring are connected to the lock body and the toggle mechanism respectively, making the overall installation simple, the spring force direction controllable, and improving the reliability of manual unlocking.

[0022] A further feature of this invention is that the control unit also includes a circuit board and a socket, and the battery box and the socket are locked or released by pressing a spring-loaded snap-fit ​​structure.

[0023] When the battery box is locked in the socket, the battery box is electrically connected to the conductive contacts inside the socket and supplies power to the circuit board.

[0024] After the battery box is released from the socket, it pops out toward the lock body.

[0025] With the above-mentioned further design, the spring-loaded snap-on structure enables the battery box to pop out with one click, eliminating the need for additional tools during replacement. The conductive contacts and snap-on design are linked, ensuring that power is switched on and off simultaneously during insertion and removal, thus eliminating the risk of short circuits.

[0026] A further feature of this invention is that two sensors are provided on the circuit board, and a detection part is provided extending outward on the transmission component. The sensors are located at the position of the detection part when the magnetic locking tongue moves to the upper or lower limit.

[0027] With the above-mentioned further configuration, the dual sensors detect the rotation limit of the transmission component, which can provide feedback on the position status of the magnetic latch to control whether the drive component rotates, preventing overload or insufficient stroke of the magnetic latch. In addition, the non-contact detection between the sensors and the detection unit can reduce mechanical wear and improve the decision accuracy of the control unit.

[0028] A further feature of this invention is that the socket has an open structure, and the spring-pressing buckle structure includes a pin on the battery box and a rebound device on the socket. The pin and the rebound device are compatible, and the circuit board is connected to the power supply inside the battery box through an electrode assembly.

[0029] The electrode assembly includes pins, conductive posts, and springs. The pins are fixed to the circuit board, and the springs are installed between the conductive posts and the pins. The springs cause the conductive posts to slide into the socket without external force.

[0030] With the above-mentioned further configuration, the spring-push conductive post structure of the electrode assembly, after being inserted into the battery box, the conductive post abuts against the conductive contact inside the battery box under the action of the spring, realizing electrical connection. At the same time, it can compensate for the positional tolerance when the battery box is inserted and removed, ensuring the stability of electrical contact. The pin, spring and conductive post form a three-level buffer design, which has strong anti-vibration performance, can extend electrical life and reduce the failure rate of poor contact.

[0040] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

If the specific posture changes, the directional indicator will also change accordingly.

In the description of this utility model, "a number" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0044] like Figure 1-8As shown, a lock includes a lock body 1 and a magnetic latch 2 that extends and retracts into and out of the lock body 1. The lock body 1 is provided with a drive component 3 and a lever component 4, wherein the lever component 4 rotates with the lock body 1. The transmission component 5 is sleeved on the outside of the lever component 4. The lock body 1 adopts a layered coaxial structure with the lever component 4 embedded inside and the transmission component 5 outside, which optimizes space utilization and avoids motion interference.

[0045] In this embodiment, the transmission component 5 and the actuating component 4 are rotatably arranged relative to each other. Both ends of the actuating component 4 are provided with first shoulders 41 to contact the upper and lower end faces of the inner cavity of the lock body 1, thereby achieving precise axial positioning of the actuating component 4. The inner cylindrical surface of the first shoulders 41 fits with the openings provided on the upper and lower end faces of the lock body 1, thereby achieving radial support of the actuating component 4.

[0046] The transmission component 5 is sleeved on the outer cylindrical surface of the first shoulder 41 and is rotatably disposed relative to it. Based on the relative rotation of the two, the sleeve can constrain the circumferential sway of the transmission component 5. A second shoulder 42 is also provided between the two first shoulders 41. The transmission component 5 is constrained between the second shoulder 42 and the inner cavity end face of the lock body 1, thereby limiting the axial displacement of the transmission component 5, thus effectively preventing the movement of the parts and making the transmission more stable.

[0047] The magnetic latch 2 extends between the drive member 3 and the actuating member 4. The lock body 1 is provided with a guide member 8. The side of the guide member 8 facing the magnetic latch 2 has a groove, and the groove guides the magnetic latch 2 to slide linearly in a directional manner.

[0048] The driving component 3 and the magnetic latch 2 are connected by a transmission component 5. The transmission component 5 rotates on the lock body 1 after being driven by the driving component 3. The actuating component 4 can be driven to rotate by inserting an external key. The transmission component 5 and the actuating component 4 rotate independently. After the actuating component 4 or the transmission component 5 rotates, it independently pushes the magnetic latch 2 to move inside the lock body 1.

[0049] Thus, the magnetic latch 2 can be pulled back by the drive component 3 to achieve automatic unlocking of the lock, or it can be manually unlocked by inserting an external key and rotating the drive toggle component 4 to achieve manual unlocking of the lock.

[0050] Automatic unlocking of the lock: The transmission component 5 includes an arc-shaped rack 51, the output end of the drive component 3 meshes with the arc-shaped rack 51, and the transmission component 5 and the magnetic latch 1 are provided with a slotted-post engagement structure. After the transmission component 5 rotates, it pushes the magnetic latch 1 to unlock through the slotted-post engagement structure.

[0051] An embodiment of the slotted column mating structure: as shown in the attached figure. Figure 7As shown, the device includes a protrusion 52 on the transmission component 5 and a groove 21 on the magnetic latch 2. The transmission component 5 abuts against the front or rear face of the groove 21 through the protrusion 52 to drive the magnetic latch 2. Through the selective abutment design between the protrusion 52 and the front and rear faces of the groove 21, the transmission component 5 can push the magnetic latch 2 to retract into the lock body 1 in one direction. Alternatively, the transmission component 5 can be reset when the magnetic latch 2 is extended by magnetic force, thus realizing the automatic unlocking drive mode.

[0052] Another embodiment of the slotted column mating structure: as shown in the attached figure. Figure 8 As shown, the device includes an arc-shaped groove 53 on the transmission component 5 and a protrusion 22 on the magnetic latch 2. The transmission component 5 abuts against the protrusion 22 through the wall of the arc-shaped groove 53 to push the magnetic latch 2 to move. The thrust is transmitted through the groove wall by the cooperation of the arc-shaped groove 53 and the protrusion 22. The arc trajectory matches the rotational motion characteristics, so that the thrust received by the magnetic latch 2 is smooth. Both sides of the arc-shaped groove 53 are supported by side walls, so that the transmission component 5 can push the magnetic latch 2 to retract into the lock body 1 in one direction. The transmission component 5 can also be reset when the magnetic latch 2 is extended by magnetic force, so as to realize the automatic unlocking drive mode.

[0053] Manual unlocking of the lock: The actuating element 4, through the contact of the protrusion 23 on the magnetic latch 2 via the actuating block 43, pushes the magnetic latch 2 to move. A return spring 7 is provided on one side of the actuating element 4, and the two ends of the return spring 7 are respectively connected to the actuating element 4 and the lock body 1. The return spring 7 is used to make the actuating element 4 reset when there is no external force. After unlocking, the key inserted from the outside is released, and the actuating element 4 is not subject to external force, so it resets. At the same time, when the door moves to the door lock area, the magnetic latch is attracted out by magnetic force. In this solution, the return spring 7 automatically returns the actuating element 4 to its original position, ensuring that the lock returns to the standby state after the key is removed, avoiding accidental operation. The two ends of the return spring 7 are respectively connected to the lock body 1 and the actuating element 4. The overall installation is simple, the spring force direction is controllable, and the reliability of manual unlocking is improved.

[0054] The lock body 1 is also provided with a control unit 6 for controlling the operation of the drive component 3. The control unit 6 includes a battery box 63 for powering the lock. The battery box 63 is detachably installed in the lock body 1. The battery box 63 is inserted and removed along the extension and retraction direction of the magnetic latch 2, and the insertion and removal interface is located on the same side end face of the lock body 1 where the magnetic latch 2 enters and exits.

[0055] Furthermore, the control unit 6 also includes a circuit board 61 and a socket 62 fixed in the lock body 1. The battery box 63 and the socket 62 are locked or released by pressing the spring-pressing buckle structure 64. When the battery box 63 is locked in the socket 62, the battery box 63 is electrically connected to the conductive contacts in the socket 62 and supplies power to the circuit board 61. After the battery box 63 is released from the socket 62, the battery box 63 pops out of the lock body 1.

[0056] Therefore, this embodiment achieves one-click pop-out of the battery box 63 by adopting a spring-pressing buckle structure 64, which eliminates the need for additional tools when replacing the battery box 63. The conductive contacts are linked with the buckle, and the power is turned on and off simultaneously when plugging and unplugging the battery box, thus eliminating the risk of short circuit.

[0057] In this embodiment, the socket 62 has an open structure. The spring-pressing buckle structure 64 includes a pin 641 disposed on the battery box 63 and a rebounder 642 disposed on the socket 62. The pin 641 and the rebounder 642 are adapted to each other. The circuit board 61 is connected to the power supply in the battery box 63 through the electrode assembly 611.

[0058] As attached Figure 5 As shown, the electrode assembly 611 includes pins 612, conductive posts 613, and springs 614. The pins 612 are fixed to the circuit board 61, and the springs 614 are installed between the conductive posts 613 and the pins 612. The springs 614 cause the conductive posts 613 to slide into the socket 62 without external force.

[0059] In this embodiment, the conductive post 613 is pushed by the spring 614 of the electrode assembly 611. After the battery box 63 is inserted, the conductive post 613 abuts against the conductive contact inside the battery box 63 under the force of the spring 614, realizing electrical connection. At the same time, it can compensate for the positional tolerance when the battery box 63 is inserted and removed, ensuring the stability of electrical contact. The pin 612, spring 614 and conductive post 613 form a three-level buffer design, which has strong anti-vibration performance, can extend electrical life and reduce the failure rate of poor contact.

[0060] Furthermore, two sensors are provided on the circuit board 61, and a detection part 54 is provided on the transmission member 5 extending outward. In this embodiment, the detection part 54 is placed opposite the arc-shaped rack 51. The circuit board 61 and its sensors are both located on the other side of the toggle member 4 relative to the magnetic latch 2, making reasonable use of the space inside the lock body 1.

[0061] The sensor is positioned at the detection unit 54 when the magnetic latch 2 moves to the upper or lower limit. After the magnetic latch 2 is driven to the unlock position by the transmission component 5, the sensor detects the position of the detection unit 54. At this time, the locking of the drive component 3 is released. When the door is closed, the magnetic latch 2 extends after being subjected to the magnetic force on the door frame, pushing the drive component 3 to rotate and reset. If the drive component 3 and the transmission component 5 are overloaded due to inertial force, another sensor can detect the position of the detection unit 54 and send a locking signal to the drive component 3 in time to stop the travel.

[0062] Therefore, by using dual sensors to detect the rotation limit of the transmission component 5, the position status of the magnetic latch 2 can be fed back to control whether the drive component 3 rotates, preventing overload or insufficient stroke of the magnetic latch 2. Furthermore, the non-contact detection of the sensors and the detection unit 54 can reduce mechanical wear and improve the decision-making accuracy of the control unit 6.

[0063] Specifically, by integrating the drive component 3, the actuating component 4, and the transmission component 5 within the lock body 1, the transmission component 5 and the actuating component 4 rotate independently. This allows the transmission component 5 to cause the magnetic latch 2 to slide, and the actuating component 4 to cause the latch to slide independently. In practical use, the lock can be unlocked by inserting an external key to drive the actuating component 4 to rotate, or the lock can be unlocked automatically by driving the transmission component 5 to rotate through the drive component 3. This achieves both automatic and manual dual-drive modes for the magnetic latch 2, providing strong flexibility. Furthermore, the overall design has fewer parts, a simplified structure, and saves space in the lock body 1.

[0064] Furthermore, the battery box 63 can be inserted and removed along the extension and retraction direction of the latch, and the interface is located on the same end face of the lock body 1 as the magnetic latch 2. Therefore, after the door is closed, the battery box is located inside the door body, and it is not easy for the battery box or even the batteries inside to come out even if it is shaken strongly. This also prevents children from accidentally disassembling the battery box, thereby ensuring reliable power supply to the lock body.
