Description

Technical Field

[0001] The present invention relates to the technical field of security locks, and in particular to a manual-automatic integrated lock device. Background Art

[0002] Locks available on the market are important anti-theft devices in security. These devices can be mechanical or electric. Universal mechanical locks are low-cost, highly reliable, and adaptable to a wide range of environments. However, mechanical keys are easily copied and offer poor confidentiality, making them unsuitable for environments requiring high security and management capabilities. Therefore, smart locks, which differ from traditional mechanical locks, offer greater intelligence in terms of user identification, security, and manageability. However, currently used electric locks cannot be manually unlocked by rotating the lock. While this intelligent, electric unlocking method introduces inconvenience, it loses its speed and convenience in the event of a power outage or motor failure, making unlocking more difficult.

[0003] Therefore, for current smart locks, especially locks that use electric unlocking and locking, it is necessary to set up backup unlocking and locking means from a safety perspective. Generally speaking, mechanical key unlocking is widely used in smart electric locks as a conventional backup option. That is, electric unlocking is used in normal unlocking and locking work, and mechanical key unlocking is used outside the door in abnormal emergency situations such as failure of the electric unlocking mechanism and insufficient power. However, electric lock body structures with different structures use different backup unlocking means and methods. In particular, when unlocking electrically and manually, the connection configuration between the structural parts used for transmission connection is not tight enough. The transmission unlocking implemented separately makes the overall layout more cumbersome and space-consuming, making it difficult to meet the demands of streamlined and convenient production and operation, and greatly affects the daily switch lock operation. Summary of the Invention

[0004] In view of this, an object of the present invention is to provide a manual-automatic integrated lock device to solve the above-mentioned problem.

[0005] The present invention adopts the following scheme:

[0006] The present application provides a manual-automatic integrated lock device, comprising a housing, an oblique lock tongue member, a middle lock tongue member, a lock core, a driving mechanism and a transmission mechanism; the housing comprises an upper cover, a bottom plate and an outer lock plate, the upper cover and the bottom plate being covered together to form an internal assembly space, and the outer lock plate is provided with a plurality of lock tongue holes; the oblique lock tongue member is correspondingly mounted in the assembly space, and the oblique lock tongue member can be operatively extended from the oblique lock tongue hole located above to lock or retract to unlock; the middle lock tongue member is correspondingly mounted in the assembly space, and the middle lock tongue member can be operatively extended from the middle lock tongue hole located below to lock or retract to unlock; the lock core is arranged on one side of the upper cover and is provided with a lock hole for receiving an external key; the driving mechanism comprises a motor assembly; the transmission mechanism comprises an unlocking assembly and a first transmission assembly and a second transmission assembly; the unlocking assembly includes a first unlocking member that is linked to the middle lock tongue member and a second unlocking member that is linked to the oblique lock tongue member; the first transmission assembly includes a gear member that is transmission-connected to the motor assembly, the gear member is meshed with the first unlocking member to automatically trigger the first unlocking member to move; the second transmission assembly includes a shift block member for manually triggering the first unlocking member to move after the lock cylinder is unlocked into place; wherein, it also includes a linkage assembly that is linked to the first unlocking member to trigger the second unlocking member to move; the linkage assembly is configured to trigger the second unlocking member to move to make the oblique lock tongue member in its unlocked state after the first unlocking member moves to make the middle lock tongue member in its unlocked state.

[0007] As a further improvement, the linkage assembly includes a rocker member corresponding to the unlocking path of the first unlocking member, and a spring member providing reset movement to the rocker member. The rocker member is synchronously linked with the second unlocking member through an adapter plate, and the adapter plate and the gear member are coaxially rotatable relative to each other.

[0008] As a further improvement, the first unlocking member is constructed as a fork structure, the active end of the fork structure is directly connected to the middle lock tongue member, and the passive end of the fork structure cooperates and links with the shift block member.

[0009] As a further improvement, the shift fork structure is provided with a transmission plate that can rotate freely coaxially with it, and the transmission plate is connected to the shift block in the form of semi-tooth engagement, and a first limit point that abuts and cooperates with the transmission plate is provided on the end face of the passive end of the shift fork structure, which is used to trigger the movement of the first unlocking member after the transmission plate abuts and cooperates with the first limit point.

[0010] As a further improvement, during manual unlocking, the shift block rotates to drive the transmission plate to move to abut against the first limit point, which triggers the shift fork structure to move to its active end to center the lock tongue member to perform the unlocking operation. Then, the shift block acts on the spring member to switch the rocker member to a position so that the rocker member drives the adapter plate to move to the second unlocking member to perform the unlocking operation on the oblique lock tongue member.

[0011] As a further improvement, the shift fork structure is also provided with a second limit point on the end face between the active end and the passive end, which cooperates with the transmission plate, so that after the key is inserted to manually lock the lock, the lock cylinder drives the shift block to drive the transmission plate to move in the opposite direction to abut against the second limit point, thereby limiting the lock cylinder from continuing to rotate.

[0012] As a further improvement, the fork structure is provided with a half-tooth portion that is half-toothedly engaged with the gear member. During automatic unlocking, the power of the motor assembly is transmitted to the half-tooth portion through the gear member; wherein, the power transmitted to the gear member causes the first unlocking member to directly rotate synchronously. After the first unlocking member completes the unlocking operation of the centering lock tongue member, the first unlocking member triggers the second unlocking member through the rocker member to further unlock the oblique lock tongue member.

[0013] As a further improvement, the middle part of the rocker member is hinged on the base plate, one end of which is connected to the axial hole of the adapter plate and has an elastic tendency to swing toward the adapter plate, and the other end is engaged with a spring member to prevent the rocker member from moving along the direction of the adapter plate; the spring member is in contact with the shift block member, and the spring member releases the limiting block on the rocker member after the shift block member rotates, thereby releasing the elastic potential energy of the rocker member to make the adapter plate rotate, thereby driving the second unlocking member to move along its unlocking path.

[0014] As a further improvement, the second unlocking member is constructed as a paddle structure, which acts on the push block of the oblique lock tongue member in an axial pushing manner to trigger the oblique lock tongue member to perform elastic position switching relative to its oblique lock tongue hole.

[0015] As a further improvement, the motor assembly is arranged on the outer peripheral side of the base plate adjacent to the gear member, and the output shaft of the motor assembly is provided with a gear set meshing with the gear member.

[0016] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0017] The manual-automatic integrated lock device of the present application can be manually triggered to unlock via the lock core or automatically triggered to unlock via the motor assembly according to user needs. When manual unlocking is selected, a key is inserted into the keyhole of the lock core to trigger the dial block to rotate to drive the first unlocking member. After the first unlocking member completes the unlocking operation of the middle lock tongue member, it further triggers the second unlocking member to move through the linkage assembly to drive the oblique lock tongue member to unlock, thereby achieving manual unlocking. When automatic unlocking is selected, the motor assembly can be transmitted to the gear member, causing the first unlocking member meshed with the gear member to move along its unlocking path, thereby first triggering the first unlocking member to complete the unlocking operation of the middle lock tongue member, and then the linkage assembly triggers the second unlocking member to unlock the oblique lock tongue member, thereby achieving automatic unlocking. Moreover, the lock device has a reasonable internal structure and compact layout. Both unlocking methods use the same transmission mechanism. The transmission method is convenient and fast, making the lock opening and closing operations more convenient, improving the convenience and operability of unlocking, and making it convenient for users to choose the unlocking method according to the situation. It has high practical value and promotion value, and significantly enhances the competitiveness of the product. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention for which protection is sought, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Example

[0028] Combine Figures 1 to 7 This embodiment provides a manual-automatic integrated lock device, including: a housing, an oblique lock tongue member 4, a middle lock tongue member 6, a lock core 8, a drive mechanism and a transmission mechanism.

[0029] The housing comprises an upper cover 1, a base plate 2, and an outer lock plate 3. The upper cover 1 and base plate 2 overlap to form an internal assembly space, and the outer lock plate 3 is provided with multiple lock bolt holes. An oblique lock bolt 4 is mounted within the assembly space and can be extended from an upper oblique lock bolt hole 5 to lock or retract to unlock. A central lock bolt 6 is mounted within the assembly space and can be extended from a lower central lock bolt hole 7 to lock or retract to unlock.

[0030] The lock core 8 is disposed on one side of the upper cover 1 and has a lock hole for receiving an external key. The drive mechanism includes a motor assembly 9. The transmission mechanism includes an unlocking assembly, a first transmission assembly, and a second transmission assembly.

[0031] The unlocking assembly includes a first unlocking member 10 that cooperates with the central lock bolt 6 and a second unlocking member 11 that cooperates with the oblique lock bolt 4. The first transmission assembly includes a gear member 12 that is in transmission connection with the motor assembly 9. The gear member 12 engages with the first unlocking member 10 to automatically trigger the movement of the first unlocking member 10. The second transmission assembly includes a shifting block member 13 for manually triggering the movement of the first unlocking member 10 after the lock cylinder 8 is fully unlocked.

[0032] The transmission mechanism of the lock device further includes a linkage assembly that is linked to the first unlocking member 10 to trigger the movement of the second unlocking member 11. The linkage assembly is configured to trigger the movement of the second unlocking member 11 to bring the oblique lock bolt member 4 into its unlocked state after the first unlocking member 10 moves to bring the middle lock bolt member 6 into its unlocked state.

[0033] The manual-automatic integrated lock device described above can be manually triggered to unlock via the lock core 8 or automatically triggered to unlock via the motor assembly 9 according to user needs. When manual unlocking is selected, a key is inserted into the keyhole of the lock core 8 to trigger the shifting block 13 to rotate to drive the first unlocking member 10. After the first unlocking member 10 completes the unlocking operation of the middle lock tongue member 6, it further triggers the second unlocking member 11 to move through the linkage assembly to drive the oblique lock tongue member 4 to unlock, thereby achieving manual unlocking. When automatic unlocking is selected, the motor assembly 9 can be transmitted to the gear member 12, so that the first unlocking member 10 meshing with the gear member 12 moves along its unlocking path, thereby first triggering the first unlocking member 10 to complete the unlocking operation of the middle lock tongue member 6, and then the linkage assembly triggers the second unlocking member 11 to unlock the oblique lock tongue member 4, thereby achieving automatic unlocking.

[0034] The lock device in this embodiment has a reasonable internal structure and a compact layout. Both unlocking methods use the same transmission mechanism. The transmission method is convenient and fast, making the lock opening and closing operations more convenient, and can improve the convenience and operability of unlocking, making it convenient for users to choose the unlocking method according to the situation. It has high practical value and promotion value, and significantly enhances the competitiveness of the product.

[0035] like Figures 4 to 6As shown, in this embodiment, the linkage assembly includes a rocker member 14 positioned along the unlocking path of the first unlocking member 10, and a spring member 15 that provides return motion to the rocker member 14. The rocker member 14 is synchronously linked to the second unlocking member 11 via an adapter plate 16. The adapter plate 16 and the gear member 12 are coaxially rotatable relative to each other. Obviously, the adapter plate 16 and the gear member 12 are relatively movable, so that rotation of the gear member 12 does not cause the adapter plate 16 to rotate synchronously. The adapter plate 16 is merely coaxial with the gear member 12; the two do not rotate together. This ensures that each time the second unlocking member 11 is triggered, the adapter plate 16 receives the corresponding power from the rocker member 14. The primary purpose of coaxially arranging the adapter plate 16 and the gear member 12 via a rotating shaft is to ensure a tighter and more efficient linkage between the second unlocking member 11 and the first unlocking member 10, thereby occupying a smaller installation space and significantly improving the transmission efficiency of the transmission mechanism.

[0036] In a preferred embodiment, the first unlocking member 10 is constructed as a shift fork structure, with its active end directly connected to the middle locking bolt member 6 and its passive end cooperating with the shift block member 13. The shift fork structure is equipped with a transmission plate 17 that freely rotates coaxially with it. Obviously, the transmission plate 17 and the shift fork structure are also configured to move relative to each other, and the two do not rotate with each other. The transmission plate 17 is connected to the shift block member 13 in a semi-toothed meshing manner. The passive end of the shift fork structure is equipped with a first stop point 18A that abuts against the transmission plate 17. When the transmission plate 17 abuts against the first stop point 18A, the first unlocking member 10 is triggered accordingly.

[0037] It should be noted that in this embodiment, the shift block 13 is disposed on the outer periphery of the lock cylinder 8. Only after the key is aligned and inserted into the lock hole of the lock cylinder 8 and rotated can the shift block 13 rotate along its arrangement direction, correspondingly driving the transmission plate 17 to engage and rotate until it abuts the first limit point 18A, at which point the shift fork structure can move along its unlocking path. This configuration ensures that during automatic unlocking, the movement of the shift fork structure does not affect the transmission plate 17 and the shift block 13. At this time, the transmission plate 17 and the shift block 13 are stationary, and only the shift fork structure moves along the unlocking path. The shift block 13 and the transmission plate 17 only serve as driving elements during manual unlocking.

[0038] Specifically, during manual unlocking, the shifting member 13 rotates, driving the transmission plate 17 to abut against the first limit point 18A. This triggers the shift fork structure to move to its active end, unlocking the central locking bolt 6. Subsequently, the shifting member 13 acts on the spring member 15, shifting the rocker member 14 to a position where it drives the adapter plate 16 to the second unlocking member 11, unlocking the oblique locking bolt 4. This allows the first unlocking member 10 to unlock before the second unlocking member 11. The specific linkage mechanism of the rocker member 14 will be further explained below.

[0039] Furthermore, the shift fork structure is provided with a second limit point 18B on the end surface between the active end and the passive end, which abuts against the transmission plate 17. After the key is inserted and the lock is manually locked, the lock cylinder 8 drives the shift block 13 to drive the transmission plate 17 to move in the opposite direction until it abuts against the second limit point 18B, thereby limiting the further rotation of the lock cylinder 8. Therefore, the first limit point 18A and the second limit point 18B are provided on the end surface of the shift fork structure respectively for limiting the movable travel of the transmission plate 17. In this way, two opposing abutting forces are fed back to the lock cylinder 8 during manual unlocking, and corresponding linkage occurs for manual unlocking (achieved by the transmission plate 17 abutting against the first limit point 18A and thus triggering the movement of the first unlocking member 10) and reminding the user to complete manual anti-locking after the lock is in place (achieved by stopping the key rotation after the transmission plate 17 abuts against the second limit point 18B).

[0040] In one embodiment, the shift fork structure is provided with a half-tooth portion 19 that partially meshes with the gear member 12. During automatic unlocking, power from the motor assembly 9 is transmitted to the half-tooth portion 19 via the gear member 12. The power transmitted to the gear member 12 causes the first unlocking member 10 to directly and synchronously rotate. After the first unlocking member 10 completes the unlocking operation on the central lock bolt member 6, the first unlocking member 10 correspondingly triggers the second unlocking member 11 via the rocker member 14 to further unlock the oblique lock bolt member 4.

[0041] It should be noted that, in order to reduce the risk of power from the relatively movable shift fork structure acting on gear member 12 being directly fed back to motor assembly 9 during manual unlocking, gear member 12 can be configured as a separate component: a shift fork tooth 20 meshing with the shift fork structure, and an output tooth 21 meshing with motor assembly 9. The shift fork tooth 20 and output tooth 21 are coaxially arranged to transmit power to each other, while the output tooth 21 is equipped with a one-way bearing or a structure that only allows it to output power along the motor assembly 9. This ensures that during manual unlocking, power fed back from the shift fork structure is only transmitted to the shift fork tooth 20, while the output tooth 21 receives no power and slips relative to the shift fork tooth 20. During automatic unlocking, power from the motor assembly 9 is transmitted to the output tooth 21 and the shift fork tooth 20. Due to the power transmission method of the one-way bearing, power is then transmitted to the shift fork structure. This ensures that interference between the various transmission components during the two different unlocking modes does not occur, significantly improving the effectiveness and service life of the transmission mechanism.

[0042] like Figure 4 and Figure 5 As shown, with respect to the specific configuration of the rocker member 14 in the linkage assembly, in this embodiment, the middle portion of the rocker member 14 is hinged to the base plate 2. One end of the rocker member 14 is connected to the axial hole of the adapter plate 16 and has an elastic tendency to swing toward the adapter plate 16. The other end of the rocker member 14 is engaged with the spring member 15 to prevent the rocker member 14 from moving along the adapter plate 16. The spring member 15 abuts against the shifting block 13. When the shifting block 13 rotates, the spring member 15 releases the restraining force on the rocker member 14, releasing the elastic potential energy of the rocker member 14, allowing the adapter plate 16 to rotate, thereby driving the second unlocking member 11 to move along its unlocking path. Obviously, the rocker member 14 itself has elastic potential energy toward triggering the second unlocking member 11 to unlock. Under the constraint of the spring member 15, the elastic potential energy is stored to ensure that the rocker member 14 is in the initial position until the shift block 13 squeezes the spring member 15 to release the lock of the spring member 15 on the rocker member 14. At this time, the elastic potential energy is immediately released, and the rocker member 14 is switched to the position where it triggers the second unlocking member 11 to unlock, thereby ensuring the power transmission of the linkage assembly.

[0043] In this embodiment, the adapter plate 16 is coaxially mounted below the gear member 12 and is rotatable, without interfering with the gear member 12. The adapter plate 16 abuts the second unlocking member 11 at its end, away from the shaft hole, thereby pushing the second unlocking member 11 along its unlocking path to unlock the door.

[0044] like Figure 1 and Figure 2As shown, in this embodiment, the second unlocking member 11 is constructed as a paddle structure. This paddle structure acts axially on the push block 22 of the oblique lock bolt member 4, triggering the oblique lock bolt member 4 to elastically shift its position relative to its oblique lock bolt hole 5. The paddle structure is linked to a fixed structure 23 via a fixed column. The oblique lock bolt member 4 is mounted on the base plate 2 via the push block 22 and its spring 24, and is further controlled by the fixed structure 23 to shift between extending to lock and retracting to unlock. The coordination between the paddle structure and the oblique lock bolt member 4 is a conventional transmission connection and will not be described here.

[0045] like Figure 5 As shown, in this embodiment, the motor assembly 9 is disposed on the outer circumference of the base plate 2 adjacent to the gear member 12. The output shaft of the motor assembly 9 is provided with a gear set 25 that meshes with the gear member 12. The motor assembly 9 is concealed within a frame structure, and its gear set is at least partially exposed on an end surface of the frame structure for meshing with the gear member 12 to achieve power output from the motor.

[0046] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
