Description

Technical Field

[0001] This utility model relates to the field of electronic lock technology, specifically to an electromechanical-separated electronic lock. Background Technology

[0002] An electronic lock is an electronic product that controls the circuitry through password input or other means, thereby enabling a motor to control the opening and closing of a mechanical switch to complete the unlocking and locking tasks.

[0003] The applicant previously submitted an application for indoor electronic lock body with application number 202410380227.7. This technical solution uses a motor to drive the movable bolt. When unlocking, the motor drives the linkage slide to move towards the second mating part. After the translation output part abuts against the second mating part, it drives the swinging part to rotate. Meanwhile, the first mating part abuts against the electric linkage part, thereby causing the linkage part to drive the movable bolt to retract into the mounting cavity. After the movable bolt exits the lock groove and retracts into the mounting cavity, the unlocking action is completed. When locking, the movable bolt is aligned with the lock groove. At this time, the movable bolt extends out of the lock box and inserts into the lock groove under the magnetic attraction of the latch magnet, thereby completing the locking action. This design can complete the locking action of the movable bolt without starting the motor, thereby reducing motor noise and reducing the energy consumption of the electronic lock.

[0004] Since the extension and insertion of the moving bolt relies on magnetic attraction, additional sensors are typically required to monitor its status and ensure accurate and stable insertion into the lock slot. These sensors detect in real-time whether the bolt has extended beyond the lock housing and provide feedback signals to ensure stable operation of the electronic lock. However, while the use of sensors improves the reliability and security of electronic locks, it also increases manufacturing costs, impacting cost control and market competitiveness.

This avoids the need for additional sensors to monitor the status of the movable bolt, as required in traditional electronic locks, thus effectively reducing the manufacturing cost of electronic locks. In the event of motor malfunction or electronic control system failure, the user can operate the inner handle to rotate the unlocking shaft, thereby manually unlocking the movable bolt through the action of the gears and the linkage slide block. This provides users with an additional emergency unlocking method, enhancing the security and practicality of the electronic lock. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0026] Reference Figure 1-6 An electromechanically separated electronic lock includes a latch 1, a lock housing 2 with an internal mounting cavity, a movable latch 3 located within the mounting cavity, and a motor 4. The lock housing 2 has a latch hole 201 for the movable latch 3 to extend and retract into the lock housing 2, and the latch 1 has a lock groove 101 for the movable latch 3 to be inserted into. A drive shaft 5, driven by the motor 4, is installed inside the lock housing 2. A linkage slide 6, which can be moved by the drive shaft 5, is mounted on the drive shaft 5. The linkage slide 6 is non-rotatable and is connected to one end of the movable latch 3.

[0027] Furthermore, the linkage slide 6 is provided with a linkage engagement hole through which the drive shaft 5 passes. A spring groove 601 is provided in the linkage engagement hole. A linkage spring 7, which is a compression spring, is provided in the spring groove 601 and is fitted on the drive shaft 5. The linkage spring 7 is limited and installed in the spring groove 601. A guide post 501 with radial protrusion is provided on the outer side of the drive shaft 5. The guide post 501 passes through the pitch space of the linkage spring 7 and is movably engaged, so that the motor 4 can drive the linkage slide 6 to move.

[0028] Furthermore, a rotatable unlocking shaft 8 is installed in the mounting cavity. One end of the unlocking shaft 8 is equipped with an inner handle 9 for the user to operate the unlocking shaft 8 from outside the lock box 2. The linkage slide 6 is connected to a gear condition 10 with the same direction of movement. The gear condition 10 is guided and fitted in the mounting cavity. The gear condition 10 is provided with a straight toothed section 1001. The unlocking shaft 8 is provided with a gear section 801 that meshes with the straight toothed section 1001.

[0029] When the motor 4 of the electronic lock is unlocking normally, the motor 4 controls the movable bolt 3 to retract into the lock box 2 to achieve the unlocking action. The control circuit of the electronic lock waits for a preset time before controlling the motor 4 to reset, so that the linkage slide 6 is reset, the movable bolt 3 returns to the state of being extended outside the lock box 2, and the linkage spring 7 returns to the unfolded state. In this way, the movable bolt 3 can collide with the latch 1 during the closing process, so that the movable bolt 3 retracts into the lock box 2 and compresses the linkage spring 7. After the movable bolt 3 corresponds to the latch slot 101, the linkage spring 7 unfolds and pushes the movable bolt 3 into the latch slot 101 to complete the locking action.

[0030] When the motor 4 of the electronic lock malfunctions, the user uses the inner handle 9 to rotate the unlocking shaft 8 in the first direction. The gear condition 10, under the meshing transmission of the straight gear section 1001 and the gear section 801, moves away from the latch hole 201. At this time, the gear condition 10 synchronously drives the linkage slide 6 to move, causing the linkage slide 6 to synchronously drive the movable latch 3 back into the mounting cavity, thus achieving the unlocking action. Furthermore, during this process, since the drive shaft 5 does not rotate, the linkage spring 7 is synchronously compressed when the linkage slide 6 moves. After the user releases the inner handle 9, the linkage spring 7 unfolds, driving the linkage slide 6 and the gear condition 10 to reset, causing the movable latch 3 to extend out of the lock box 2 from the latch hole 201. This structure, through the linkage spring 7 driving the movable latch 3 to extend and insert into the latch slot 101, eliminates the need for a sensor to detect whether the movable latch 3 is in motion.

[0031] In this embodiment, the linkage slide 6 is provided with a linkage protrusion 602, and the tooth condition 10 is provided with a rack hook 1002 hooked on the linkage protrusion 602. So when the tooth condition 10 is driven away from the lock tongue hole 201 by the unlocking shaft 8, the tooth condition 10 can use the action of the rack hook 1002 to pull the linkage slide 6 to move synchronously, thereby linking the movable lock tongue 3 to retract into the mounting cavity and realize unlocking. After the user releases the inner handle 9, the linkage spring 7 unfolds and drives the linkage slide 6 to move and reset. The linkage protrusion 602 pushes the rack hook 1002 synchronously, so that the tooth condition 10 and the inner handle 9 reset at the same time.

[0032] In a preferred embodiment, the spring groove 601 is provided with a spring positioning groove 603 for limiting rotation, and both ends of the linkage spring 7 are provided with spring inserts 701 that are inserted into the spring positioning groove 603 to achieve positioning, so that the linkage spring 7 cannot rotate and the linkage spring 7 is positioned and installed.

[0033] In this embodiment, a main mounting seat 11 is provided in the mounting cavity. The main mounting seat 11 is fixed to the lock box 2 by bolt installation. The main mounting seat 11 is provided with a drive mounting groove 111 and a sliding mounting groove 112. The motor 4 is installed in the drive mounting groove 111. The linkage slide 6 is guided and fitted in the sliding mounting groove 112. The two ends of the sliding mounting groove 112 are respectively provided with a first rotation position and a second rotation position. One end of the drive shaft 5 is provided with a first shaft portion that can be rotatably fitted in the first rotation position, and the other end is provided with a second shaft portion that can be rotatably fitted in the second rotation position. The diameters of the first shaft portion and the second shaft portion are both smaller than the diameter of the drive shaft 5, so that the drive shaft 5 can be rotatably installed in the sliding mounting groove 112.

[0034] In this embodiment, the first shaft and the output shaft of the motor 4 are connected by a gear transmission structure 200. The main mounting base 11 is provided with a transmission mounting groove 113. The first rotating part communicates with the transmission mounting groove 113. One end of the drive mounting groove 111 is provided with a transmission clearance part communicating with the transmission mounting groove 113. The output shaft of the motor 4 extends into the transmission mounting groove 113 through the transmission clearance part and is connected to the action output end of the gear transmission structure 200. The first shaft is connected to the action output end of the gear transmission structure 200. Specifically, the gear transmission structure 200 includes a driving gear, a driven gear, and a transmission gear. The driving gear is fixedly sleeved on the output shaft of the motor 4. The driven gear is integrally formed on the first shaft. The transmission gear is rotatably installed in the transmission mounting groove 113. The transmission gear meshes with the driving gear and the driven gear simultaneously, thereby enabling the motor 4 to drive the shaft 5 to rotate.

[0035] In this embodiment, the main mounting base 11 is provided with a secondary mounting base 12 for closing the drive mounting groove 111, the sliding mounting groove 112, and the transmission mounting groove 113. The secondary mounting base 12 can limit the motor 4, drive shaft 5, linkage slide 6, and gear transmission structure 200 to prevent them from falling out of their mounting positions. Furthermore, the main mounting base 11 is provided with a fastening part 114, and the secondary mounting base 12 is provided with a fastening groove that forms a snap-fit ​​with the fastening part 114, thereby achieving the purpose of snap-fitting the secondary mounting base 12 onto the main mounting base 11.

[0036] In this embodiment, to facilitate the installation of the unlocking shaft 8, a shaft mounting seat 13 is fixedly installed in the mounting cavity. The shaft mounting seat 13 is integrally formed and connected with the main mounting seat 11. The shaft mounting seat 13 is provided with a gear receiving groove 131 and a first shaft hole that axially penetrates one end of the gear receiving groove 131. A second shaft hole corresponding to and communicating with the gear receiving groove 131 is provided on one outer side of the lock box 2. The first shaft hole and the second shaft hole are both used for the rotational guidance of the unlocking shaft 8. The two ends of the unlocking shaft 8 can rotatably pass through the first shaft hole and the second shaft hole, respectively. The gear part 801 is located in the gear receiving groove 131 and cannot move axially. The shaft mounting seat 13 is provided with a clearance for the gear part 801 to cooperate with the straight gear part 1001.

[0037] In this embodiment, the movable latch 3 is either a slanted latch or a three-pronged latch, preferably a three-pronged latch for higher security. Since the latching surfaces of the slanted and three-pronged latches have different orientations when colliding with the lock hole, to allow the movable latch 3 to change the orientation of its latching surface according to different door opening directions, the movable latch 3 is connected to a latch limiting member 14 and a linkage slide block 6. The latch limiting member 14 is detachable. The movable latch 3 is configured to rotate 180° to change direction after the latch limiting member 14 is removed and the movable latch 3 disengages from the latch hole 201. That is, after removing the latch limiting member 14, the movable latch 3 can first disengage from the latch hole 201 and then rotate 180°, thereby changing the orientation angle of the latch mating surface of the movable latch 3 to meet the requirements of electronic locks for different door opening methods.

[0038] In this embodiment, one end of the movable latch 3 is provided with a latch shaft 301, and the other end of the latch shaft 301 is provided with a latch insertion shaft 302. The portion of the other end face of the latch shaft 301 that is not connected to the latch insertion shaft 302 forms a latch limiting surface. The linkage protrusion 602 of the linkage slide 6 is provided with a latch shaft hole. The latch limiting surface movably presses against one end of the linkage protrusion 602. After the latch insertion shaft 302 passes through the latch shaft hole, the latch limiting member 14 is installed. The latch limiting member 14 movably presses against the other end of the linkage protrusion 602. Thus, the movable latch 3 and the linkage slide 6 are combined and connected together by the action of the latch limiting surface and the latch limiting member 14. Furthermore, the latch insertion shaft 302 is provided with a pin hole, and the latch limiting member 14 is a pin that is inserted into the pin hole.

[0039] In this embodiment, the bolt hole 201 has two first guide structures arranged symmetrically vertically and two second guide structures arranged symmetrically front to back on its hole wall. The first guide structure includes a guide protrusion 2011, and the second guide structure includes a guide groove 2012. The upper and lower sides of the movable bolt 3 are provided with bolt grooves 303 that guide and cooperate with the guide protrusions 2011, and the bolt grooves 303 on the upper and lower sides of the movable bolt 3 are symmetrically arranged. The left and right sides of the movable bolt 3 are provided with bolt mating parts 304 that guide and cooperate with the guide grooves 2012, and the bolt mating parts 304 on the left and right sides of the movable bolt 3 are symmetrically arranged. The above structure can realize the purpose of movable guide mating in the bolt hole 201, and the symmetrical design also facilitates the installation of the movable bolt 3 after reversal.

[0040] In this embodiment, a limiting seat 15 is fixedly provided in the mounting cavity. The limiting seat 15 is provided with a limiting through hole for the locking tongue shaft 301 to pass through. The limiting through hole is used to guide the axial movement of the locking tongue shaft 301, and can also prevent the linkage protrusion 602 from continuing to move towards the locking tongue hole 201, thereby ensuring the quality of the movable locking tongue 3 extending out.

[0041] In this embodiment, the inner handle 9 is located on the other side of the lock box 2. The other side of the lock box 2 is provided with a handle mounting hole. The unlocking shaft 8 is provided with a transmission linkage groove 802. The inner handle 9 is provided with a connecting shaft 901 that can be rotatably mounted on the handle mounting hole. One end of the connecting shaft 901 is provided with a handle coaxial linkage part 902 that matches the transmission linkage groove 802, so that the inner handle 9 and the unlocking shaft 8 can rotate synchronously.

[0042] In this embodiment, an outer mounting base 16 corresponding to the second shaft hole is provided on one outer side of the lock box 2. A rotatable outer drive shaft 17 is provided inside the outer mounting base 16. One end of the outer drive shaft 17 is provided with an outer linkage part 171 that engages in the transmission linkage groove 802, and the other end is provided with a rotation positioning part 172 extending out of the outer mounting base 16. A lock cylinder mating hole 173 is provided inside the outer drive shaft 17 for the mating shaft 302 of the lock cylinder 301 of the outer door handle 300 to be inserted. Thus, the lock cylinder 301 of the outer door handle 300 can control the unlocking shaft 8 to rotate and unlock via the mating shaft 302. The outer door handle 300 is provided with a rotation positioning groove for the rotation positioning part 172 to be rotatably installed, thereby improving the assembly quality of the electronic lock and the outer door handle 300. The outer mounting base 16 and the outer drive shaft 17 can shorten the length of the mating shaft 302 of the outer door handle 300, and also improve the quality of the transmission between the mating shaft 302 and the unlocking shaft 8. In addition, the outer mounting base 16 can be detachably installed on the outer side of the lock box 2 by bolt installation, so that in other embodiments, the design of the outer mounting base 16 can be directly removed and eliminated, allowing the mating shaft 302 to be mated in the transmission linkage groove 802 to realize the transmission between the mating shaft 302 and the unlocking shaft 8.

[0043] In this embodiment, the lock box 2 includes a first box body and a second box body mounted on the first box body. The inner cavity of the first box body and the inner cavity of the second box body are combined to form the mounting cavity. The main mounting seat 11 is mounted in the inner cavity of the first box body.
