Description

Technical Field

[0001] This utility model relates to the field of lock technology, and in particular to a lock body in which the electric drive and lock cylinder drive are separated. Background Technology

[0002] Electronic door locks are based on traditional door locks, adding an electric unlocking mechanism. This allows for both cylinder-based unlocking and electric unlocking operations, using an internal linkage structure to drive the same bolt for both opening and closing, creating a dual unlocking path. However, existing lock body structures have the following problems: 1) The existing lock body structure does not separate from the lock cylinder dial during the operation of electric or lever lock, which greatly reduces the life of the lock cylinder dial and the hidden dangers when using the lock cylinder to open and close the lock; or, while separating from the lock cylinder, the lock cylinder unlocking becomes counterclockwise rotation, which changes the user's habits and is not conducive to the operation of unlocking the lock cylinder in normal or emergency situations.

[0003] 2) The existing lock body separates from the lock cylinder, but changes the rotation direction of the lock cylinder when opening and closing, such as rotating counterclockwise to unlock and rotating clockwise to lock, thus changing the user's usage habits. Utility Model Content

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figures 1 to 4 As shown, this utility model discloses a lock body with separate electric drive and lock cylinder drive switching mechanism, comprising a main lock rack 1, upper and lower hooks 2, lower hooks 3, handle switch lock assembly 4, lock cylinder switch lock assembly 5, electric switch lock assembly 6, latch bolt assembly 7, main bolt assembly 8, and lock housing 9. The main lock rack 1, upper and lower hooks 2, lower hooks 3, latch bolt assembly 7, and main bolt assembly 8 are movably connected within the lock housing 9. The handle switch lock assembly 4, lock cylinder switch lock assembly 5, and electric switch lock assembly 6 are installed within the lock housing 9. The manual lock assembly 4, the lock cylinder lock assembly 5, and the electric lock assembly 6 are respectively connected to the main lock rack 1. The main lock rack 1 is provided with a first S-groove 101, the lower deadbolt 3 is provided with a second S-groove 301, and the upper deadbolt 2 is provided with a third S-groove 201. The main latch assembly 8 is provided with a main latch positioning post 801, which is in movable cooperation with the first S-groove 101, the second S-groove 301, and the third S-groove 201. The latch assembly 7 is respectively connected to the main lock rack 1 and the handle lock assembly 4.

[0019] In this invention, the direction of movement of the deadbolt within the lock housing 9 is taken as vertical, and the direction of movement of the main tongue assembly 8 within the lock body is taken as horizontal. The vertical movement of the main lock rack 1 can be driven by the handle switch lock assembly 4, the lock cylinder switch lock assembly 5, and the electric switch lock assembly 6 respectively. When the main lock rack 1 moves vertically, it will simultaneously drive the latch assembly 7 and the main latch assembly 8 to complete the unlocking action, or drive the main latch assembly 8 to complete the locking action. The first S groove 101 of the main lock rack 1 drives the main latch positioning post 801 to move in the groove, thereby realizing the lateral movement of the main latch assembly 8 to complete the locking and unlocking. At the same time, due to the linkage between the second S groove 301, the third S groove 201 and the main latch positioning post 801, while the main latch assembly 8 moves laterally, the main latch positioning post 801 drives the lower hook 3 and the upper hook 2 to move vertically through the second S groove 301 and the third S groove 201 respectively. This achieves the simultaneous locking and unlocking of the lower hook 3 and the upper hook 2 while the main latch assembly 8 completes the locking and unlocking, thus achieving multi-point fixation of the lock on the door or door frame.

[0020] The lock housing 9 is provided with a main lock guide post 901 and a deadbolt guide post 902. The main lock rack 1 is provided with a vertical main lock guide hole 102. The upper deadbolt 2 and the lower deadbolt 3 are both provided with vertical deadbolt guide holes 202 / 302. The main lock guide hole 102 cooperates with the main lock guide post 901, and the deadbolt guide holes 202 / 302 cooperate with the deadbolt guide post 902. The second S groove 301 and the third S groove 201 intersect each other in space at the position of the main tongue positioning post 801.

[0021] The first S-groove 101 is inclined in both vertical and horizontal directions, which can convert the vertical movement of the main lock rack 1 into the horizontal movement of the main tongue positioning post 801, thereby driving the main tongue assembly 8 to move horizontally. The two ends of the first S-groove 101 are provided with corner positions. When the main tongue positioning post 801 moves to the two end positions of the first S-groove 101, it can be locked in the lower corner position to prevent the main tongue positioning post 801 from sliding when the main lock rack 1 is not driven. The second S-groove 301 and the third S-groove 201 also adopt a similar inclined orientation structure to the first S-groove 101, and the inclination angles of the second S-groove 301 and the third S-groove 201 are opposite, that is, they intersect each other in space at the position of the main tongue positioning post 801. While the main tongue positioning post 801 moves laterally driven by the main lock rack 1, it is linked with the second S-groove 301 and the third S-groove 201, so that the lower hook 3 and the upper hook 2 move in opposite vertical directions, so that while the main tongue assembly 8 extends laterally, the upper hook 2 extends vertically to the top of the lock housing 9, and the lower hook 3 extends vertically to the bottom of the lock housing 9. The main lock guide hole 102 and the main lock guide post 901 cooperate to limit the vertical movement trajectory of the main lock rack 1 within the lock housing 9. Thus, during vertical movement, the first S-groove 101 generates a force that is applied to the main tongue positioning post 801 to drive the main tongue to move laterally. The top and bottom hook guide holes 202 / 302 and the top and bottom hook guide post 902 cooperate to limit the vertical movement trajectory of the upper top and bottom hooks 2 and the lower top and bottom hooks 3 within the lock housing 9. Thus, the main tongue positioning post 801 generates a force that is applied to the third S-groove 201 and the second S-groove 301 to drive the upper top and bottom hooks 2 and the lower top and bottom hooks 3 to move vertically.

[0022] The lock body, which separates the electric drive and the lock cylinder drive, also includes a top and bottom hook limiting plate 10 and a top and bottom hook limiting torsion spring 1001. The lock shell 9 is provided with a top and bottom hook rotating column 903. The top and bottom hook limiting plate 10 is movably connected to the top and bottom hook rotating column 903. One end of the top and bottom hook limiting torsion spring 1001 abuts against the lock shell 9, and the other end abuts against the top and bottom hook limiting plate 10. The top and bottom hook limiting plate 10 is respectively limited and engaged with the main lock rack 1, the lower top and bottom hook 3 or the upper top and bottom hook 2.

[0023] The top and bottom hook limiting plate 10 swings around the top and bottom hook rotating column 903. Under the elastic force of the top and bottom hook limiting torsion spring 1001, the top and bottom hook limiting plate 10 is tightly attached to the main lock rack 1. When locking, the main lock rack 1 moves and pushes the top and bottom hook limiting plate 10 to swing, so that the top and bottom hook limiting plate 10 switches between the state of being locked and disengaged from the top and bottom hooks. The attached drawings of this utility model show the cooperation structure between the lower top and bottom hooks 3 and the top and bottom hook limiting plate 10. However, similarly, the position of the top and bottom hook limiting plate 10 can be adjusted to cooperate with the upper top and bottom hooks 2 as needed. Alternatively, the corresponding locking structure can be set at both the lower top and bottom hooks 3 and the upper top and bottom hooks 2.

[0024] The main lock rack 1 is provided with a limiting protrusion 103, and limiting grooves 104 are formed on both sides of the limiting protrusion 103. The lower hook 3 or the upper hook 2 is provided with hook locking positions 303. The hook limiting piece 10 is provided with a limiting protrusion 1002 and a limiting arm 1003. In the unlocked state, the limiting protrusion 1002 slides into the limiting groove 104 on one side of the limiting protrusion 103, and the limiting arm 1003 is misaligned with the hook locking position 303. In the locked state, the limiting protrusion 1002 crosses the limiting protrusion 103 and slides into the limiting groove 104 on the other side, and the limiting arm 1003 is locked into the hook locking position 303.

[0025] When the main lock rack 1 moves, the limiting protrusion 103 pushes up the limiting protrusion 1002, causing the entire locking plate 10 to tilt upwards until it crosses the limiting protrusion 103. Under the action of the locking torsion spring 1001, the limiting protrusion 1002 returns to its original position and engages with the limiting grooves 104 on both sides of the limiting protrusion 103, completing the locking and unlocking action. At the same time as the locking plate 10 tilts upwards, the limiting arm 1003 is also lifted. At this time, the lower locking plate 3 or the upper locking plate 2 will move relative to the locking plate 10, and the limiting arm 1003 is just offset so as not to obstruct the movement of the lower locking plate 3 or the upper locking plate 2. When locking, the deadbolt locking position 303 moves to align with the limiting arm 1003, and as the limiting protrusion 1002 resets, it locks into the limiting groove 104. The limiting arm 1003 also locks into the deadbolt locking position 303, locking the position of the lower deadbolt 3 or the upper deadbolt 2. When unlocking, the limiting arm 1003 is pushed up by the limiting protrusion 1002 and disengages from the deadbolt locking position 303. After the lower deadbolt 3 or the upper deadbolt 2 moves in the opposite direction, the limiting arm 1003 will be misaligned with the deadbolt locking position 303. At this time, after the deadbolt limiting piece 10 resets, it will not lock the lower deadbolt 3 or the upper deadbolt 2.

[0026] The latch assembly 7 includes a latch lever 701, a latch guide plate 702, a latch separation plate 703, a latch 704, and a latch return spring 705. The lock housing 9 is provided with a latch rotating post 904 and a latch guide post 905. The main lock rack 1 is provided with a latch lever 105. The latch lever 701 is movably connected to the latch rotating post 904. The latch guide plate 702 is provided with a transverse latch guide groove 706, which cooperates with the latch guide post 905. The lever arm on one side of the latch lever 701 is connected to the latch lever. The post 105 is connected, and the lever arm on the other side of the tongue lever 701 is connected to one end of the tongue guide plate 702. The other end of the tongue guide plate 702 is fastened to the tongue separation plate 703. The tongue separation plate 703 is provided with a transverse tongue sliding groove 707. The tongue sliding groove 707 cooperates with the tongue guide post 905. The tongue 704 is connected to the tongue separation plate 703 and passes through the side of the lock housing 9. One end of the tongue return spring 705 abuts against the lock housing 9, and the other end of the tongue return spring 705 abuts against the tongue separation plate 703.

[0027] The latch separation plate 703 guides the lateral movement of the latch separation plate 703 through the movable cooperation between the latch bolt 704 and the lock housing 9, and the cooperation between the latch bolt sliding groove 707 and the latch bolt guide post 905. The latch separation plate 703 itself can move freely under the action of external force. When there is no other external force, the latch bolt return spring 705 will push against the latch separation plate 703, so that the latch bolt 704 is in the extended state and the lock is closed. When subjected to the force of the lever switch lock assembly 4, or the force applied by the main lock through the latch bolt guide plate 702, the latch separation plate 703 will overcome the latch bolt return spring 705 and move inward towards the lock housing 9 to perform the unlocking action. When the main lock rack 1 is unlocked, its vertical movement drives the latch pin 105 to push the lever arm on one side of the latch lever 701, causing the latch lever 701 to rotate around the latch rotating column 904. Simultaneously, this rotates the lever arm on the other side of the latch lever 701, actuating the latch guide plate 702. The latch guide plate 702, in conjunction with the latch guide groove 706 and the latch guide column 905, moves laterally. This linkage between the latch lever 701 and the latch separation plate 703 is achieved through the latch guide plate 702, causing the latch separation plate 703 to move inwards towards the lock housing 9, overcoming the latch return spring 705. For spatial considerations, the latch rotating column 904 and the deadbolt rotating column 903 in this invention can share the same column.

[0028] The lever switch lock assembly 4 includes a lever head 401, a lever plate 402, and a lever positioning post 403. The lever head 401 is rotatably connected to the lock housing 9, the lever positioning post 403 is connected to the lock housing 9, and the lever plate 402 is rotatably connected to the lever positioning post 403. The two ends of the lever plate 402 relative to the lever positioning post 403 are respectively connected to one side swing arm of the lever head 401 and the tongue separation plate 703, and the other side swing arm of the lever head 401 is connected to the main lock rack 1.

[0029] The handle lever head 401 is used to assemble the handle. The handle lever head 401 may contain a handle return torsion spring 404 or a structure that does not require the handle return torsion spring 404. Unlocking is achieved by simply turning the handle clockwise. The handle positioning post 403 is essentially the lever center of the mating positions at both ends of the handle lever 402. In the locked state, one end of the handle lever 402 is within the swing range of one side of the handle lever head 401 or is in contact with one side of the handle lever head 401 without exerting force. One end of the main lock rack 1 is within the swing range of the other side of the handle lever head 401 or is in contact with the other side of the handle lever head 401 without exerting force. The tongue separation plate 703 is located at the handle lever 402. 2. Within the swing range of the other end of the swing arm or in contact with the other side of the swing arm of the handle lever 402 but without force, when the user turns the handle clockwise to unlock, the handle lever head 401 pushes the main lock rack 1 to move vertically, and the main lock rack 1 completes the unlocking of the main tongue assembly 8. Simultaneously, one end of the handle lever 402 is moved, and the other end of the swing of the handle lever 402 pushes the tongue separation plate 703 to move inward toward the lock case 9 against the tongue return spring 705, and completes the unlocking of the tongue 704. After unlocking is completed and the user releases their hand, the handle lever 402 loses its force, and the latch separation plate 703 will reset under the elastic force of the latch return spring 705. At the same time, it pushes the handle lever 402 to swing back and reset. If the handle head 401 adopts the handle return torsion spring 404 structure, the handle head 401 will reset under the action of the handle return torsion spring 404. If the handle head 401 adopts the structure without handle return torsion spring 404, while the handle lever 402 swings back and resets, one end of the handle lever 402 will also push the handle head 401 to reset. After the main latch assembly 8 is unlocked, the main lock rack 1 will be stuck in the unlocking position. At this time, the main lock rack 1 is away from the other side of the handle lever 401.

[0030] The electric switch lock assembly 6 includes a main board 601, a motor gearbox assembly, and a micro switch 604. The main board 601 and the motor gearbox assembly are installed inside the lock housing 9. The motor gearbox assembly includes a drive motor 602 and a motor gear set 603. The main board 601 connects to and controls the drive motor 602. The output end of the drive motor 602 is connected to one end of the motor gear set 603, and the other end of the motor gear set 603 meshes with the main lock rack 1. The micro switch 604 is set on the moving path of the latch guide plate 702. The latch guide plate 702 has a contact position 708. When unlocking, after the latch guide plate 702 moves into position, the contact position 708 contacts the micro switch 604. The micro switch 604 is connected to the main board 601 and transmits signals.

[0031] The main lock rack 1 has a rack structure at the position where it mates with the electric switch lock assembly 6. The main board 601 controls the forward and reverse rotation of the drive motor 602. Through the meshing transmission between the motor gear set 603 and the main lock rack 1, the main lock rack 1 is driven to move vertically, completing the locking and unlocking operation. The micro switch 604 is used to detect whether the unlocking action is completed. When the unlocking is complete, the contact position 708 on the latch guide plate 702 will contact the micro switch 604. At this time, the micro switch 604 will send a feedback signal to the main board 601, and the main board 601 will stop controlling the drive motor 602 to avoid over-driving and wearing of the motor gear set 603. After the locking action is completed, the main board 601 will control the drive motor 602 to reverse a certain angle, so that the motor gear set 603 is in an idle state. In this way, even when the handle and lock cylinder are unlocking, the drive motor 602 and the motor gear set 603 will not be driven, realizing the separation between electric drive and handle drive and lock cylinder drive operations.

[0032] The motor gear set 603 includes a motor output wheel, an upper motor drive gear, and a lower motor drive gear. (See reference...) Figure 5 The structure is such that the upper gear of the motor drive is similar to the end spur gear 505, and the lower gear of the motor drive is similar to the end semi-disengaged spur gear 506. The motor output wheel is directly connected to the output end of the drive motor 602, and the drive motor 602 drives the motor output wheel to rotate. The motor output wheel meshes with the upper gear of the motor drive, and the lower gear of the motor drive meshes with the corresponding locking teeth on the main locking rack 1. The upper gear of the motor drive is provided with a free-spinning angle groove 507 and a gear limiting block 508. The lower gear of the motor drive is provided with a protruding semi-disengaged block 509, which is inserted into the free-spinning angle groove 507. When the upper gear of the motor drive rotates until the gear limiting block 508 contacts the semi-disengaged block 509, the lower gear of the motor drive is driven to rotate. After the drive motor 602 drives the motor gear set 603 to complete the shifting and locking of the main lock rack 1, the drive motor 602 drives the motor gear set 603 to reverse a certain angle, so that the half-disengagement block 509 reverses in the idle angle groove 507, so that the half-disengagement block 509 is misaligned and does not contact the gear limit block 508, ensuring that the motor gear set 603 is in an idle state. At this time, when the main lock rack 1 is moved, it will not drive the motor output wheel or the gear on the motor drive to rotate, so that the handle / lock cylinder unlocking will not drive the motor and the gear inside the gearbox.

[0033] The lock body, which separates the electric drive and the lock cylinder drive switch, also includes a Bluetooth control component 11. The Bluetooth control component 11 includes a button mounting base 1101, a Bluetooth antenna 1102, and a Bluetooth configuration button 1103. The Bluetooth antenna 1102 and the Bluetooth configuration button 1103 are installed in the button mounting base 1101, and the Bluetooth antenna 1102 and the Bluetooth configuration button 1103 are respectively connected to the main board 601.

[0034] The mainboard 601 has a built-in Bluetooth chip, and the lock body has a Bluetooth antenna 1102 installed inside. It can connect to a mobile phone via Bluetooth, requiring only power to the lock body to operate via an app, eliminating the need for traditional inner and outer panels (which use fingerprint, password, or facial recognition) for unlocking. The Bluetooth configuration button 1103 is used for configuring the Bluetooth connection. A Hall effect button 1104 is also located on the button holder 1101, connecting to the mainboard 601. A magnet is installed on the corresponding door frame of the lock body. When the door is closed, the Hall effect button 1104 senses the magnet, generating a locked signal, which is then transmitted to the mainboard 601.

[0035] like Figure 5 As shown, the lock cylinder switch lock assembly 5 includes a lock cylinder direct drive gear 501, a lock cylinder indirect drive gear set, and an end drive gear 504. The lock cylinder direct drive gear 501 is connected to the lock cylinder. The end drive gear 504 includes an end spur gear 505 and an end semi-detached spur gear 506. The end spur gear 505 and the end semi-detached spur gear 506 are coaxially connected. The lock cylinder direct drive gear 501, the lock cylinder indirect drive gear set, and the end spur gear 505 mesh sequentially. The end semi-detached spur gear 506 meshes with the main lock rack 1. The end spur gear 505 is provided with a free rotation angle groove 507 and a gear limiting block 508. The gear limiting block 508 is set in the free rotation angle groove 507. The end semi-detached spur gear 506 is provided with a protruding semi-detached block 509. The semi-detached block 509 is inserted into the free rotation angle groove 507. When the end spur gear 505 rotates until the gear limiting block 508 contacts the semi-detached block 509, it drives the end semi-detached spur gear 506 to rotate.

[0036] The lock cylinder indirect transmission gear set includes a transmission spur gear 502 and a transmission double-layer gear 503. The lock cylinder direct transmission gear 501 meshes with the transmission spur gear 502, the transmission spur gear 502 meshes with the upper gear of the transmission double-layer gear 503, and the lower gear of the transmission double-layer gear 503 meshes with the end spur gear 505. The lock cylinder direct transmission gear 501 adopts an arc-shaped opening structure, with the opening positioned to lock the lock cylinder. When the user locks the lock cylinder by turning the key, the lock cylinder direct transmission gear 501 will rotate, and through the transmission spur gear 502 and the transmission double-layer gear 503, it will drive the end spur gear 505 to rotate. When it rotates to the gear limit block 508 and the semi-disengagement block 509... After contact, the end semi-disengaged spur gear 506 rotates in the forward direction, thereby driving the main lock rack 1 to move. In this state, if the main lock rack 1 is driven to move in the reverse direction by the handle or electric means, the end semi-disengaged spur gear 506 will rotate in the reverse direction as the main lock rack 1 moves. However, since the semi-disengaged block 509 needs to travel the travel of the idle angle groove 507 before it makes reverse contact with the gear limit block 508, this travel is sufficient to cover the rotation travel of the end semi-disengaged spur gear 506. Therefore, it cannot drive the lock cylinder direct drive gear 501 or the lock cylinder indirect drive gear set in the reverse direction, so that the lock cylinder opening / closing related structural components will not be driven when the lock is opened / closed electrically. When the user unlocks the lock cylinder by turning the key, the lock cylinder directly drives the end spur gear 505 to rotate in the opposite direction through the direct drive gear 501, drive spur gear 502, and drive double-layer gear 503 until the gear limit block 508 and the half-disengagement block 509 make reverse contact. Then, the drive continues to drive the end half-disengagement spur gear 506 to rotate in the opposite direction, which in turn drives the main lock rack 1 to move in the opposite direction to complete the unlocking.

[0037] The main tongue assembly 8 includes a main tongue 802 and a main tongue frame 803. The main tongue 802 is connected to the main tongue frame 803 and passes through the side of the lock housing 9. The main tongue positioning post 801 is provided on the main tongue frame 803. The main tongue frame 803 is also provided with a transverse main tongue guide hole 804. The lock housing 9 is provided with a main tongue guide post 906. The main tongue guide hole 804 cooperates with the main tongue guide post 906.

[0038] The main tongue frame 803, through the main tongue guide hole 804 and the main tongue guide post 906, restricts the direction of lateral movement. The main tongue frame 803 serves as the mounting structure for the main tongue 802 and the main tongue positioning post 801. Under the movement of the first S-groove 101 of the main lock rack 1, the main tongue 802 extends or retracts relative to the side of the lock housing 9, achieving the locking and unlocking effects. The main tongue 802 has a cylindrical structure.

[0039] The lock case 9 has mounting holes 907 on its side, front, and side surfaces, allowing it to be installed on different surfaces using screws to meet the installation needs of different scenarios.

[0040] Each positioning and rotating pin in the lock body is equipped with a bushing 12 to limit the corresponding parts. The lock cylinder switch lock assembly 5 and the electric switch lock assembly 6 can be installed in the lock shell 9 on one side with screws. Even when the lock cover 13 is open, the parts will not fall off, which is convenient for maintenance.

[0041] This lock body includes the following types of opening and closing mechanisms: (1) The electric locking process, such as Figures 6 to 13 As shown: The mainboard 601 supplies power and signals to drive the motor 602. The gear set of the drive motor 602 rotates counterclockwise, driving the main lock rack 1 to move to the left along the main lock guide post 901 and the main lock guide hole 102 through gear and rack transmission. This forces the deadbolt limit plate 10 to overcome the elastic force of the deadbolt limit torsion spring 1001 and move upward. Figures 7 to 8 At this time, the main lock rack 1 forces the main tongue positioning post 801 riveted to the main tongue assembly 8 to extend synchronously along the first S-groove 101 on the main lock rack 1, the lower deadbolt 3 along the second S-groove 301, and the upper deadbolt 2 along the third S-groove 201 to complete the locking action. Figures 9 to 10 At this time, the limit plate 10 of the deadbolt returns to its original position under the elastic force of the deadbolt limit torsion spring 1001, and simultaneously locks the deadbolt locking position 303 on the lower deadbolt 3 to achieve a locking effect. Figure 11 After the mainboard 601 detects the completion of the locking action, it sends a signal to the drive motor 602. The drive motor 602 drives the motor gear set 603 to reverse a certain angle, ensuring that the motor gear set 603 is in an idle state. This prevents the handle / lock cylinder from driving the motor and the internal gears of the gearbox when unlocking, thus protecting the lifespan of the motor and gears. Figures 12 to 13 At this point, pressing either the main tongue assembly 8 or the upper and lower hooks 2 and 3 will not unlock the lock. Only by using a key to drive the main lock rack 1 through the lock cylinder or by using an electric drive main lock rack 1 can the hook limit plate 10 be released from the hook position 303 on the lower hook 3.

[0042] The process of detecting the completion of the locking action signal is determined by the Hall key 1104 of the lock body and the magnet. The magnet is set on the door frame and the lock body is installed on the door leaf. After the door is closed, the Hall key 1104 of the lock body on the door leaf senses the magnet on the door frame, recognizes the locking signal, and transmits the signal to the main board 601 for recognition and judgment.

[0043] The entire electric locking action does not drive the lock cylinder's opening and closing parts; the electric locking mechanism and the lock cylinder's opening and closing mechanism have an idle angle to achieve complete separation.

[0044] (2) The electric unlocking process, such as Figures 14 to 19 As shown: The mainboard 601 supplies power and signals to drive the motor 602. The gear set of the drive motor 602 rotates clockwise, driving the main lock rack 1 to move to the right along the main lock guide post 901 and the main lock guide hole 102 through gear and rack transmission. This forces the hook limit plate 10 to overcome the elastic force of the hook limit torsion spring 1001 and move upward. At this time, the hook limit plate 10 disengages from the hook locking position 303 on the lower hook 3. Figure 15 and Figure 16 As shown; at this time, the first S-groove 101 on the main lock rack 1 forces the main tongue positioning post 801 riveted to the main tongue assembly 8 to retract synchronously along the first S-groove 101 on the main lock rack 1, the lower deadbolt 3 along the second S-groove 301, and the upper deadbolt 2 along the third S-groove 201 (see reference). Figure 9 and Figure 10 (In opposite directions), the latching pin 105 riveted to the main lock rack 1 forces the latching plate 701 to rotate around the latching pin 904, and simultaneously forces the latching guide plate 702 to move upward. At the same time, the latching guide plate 702 overcomes the elastic force of the latching return torsion spring, pulling back the latching separation plate 703 and the latching tongue 704 to complete the unlocking action. The latching guide plate 702 has a contact position 708, and a micro switch 604 is located at the position. When the latching tongue 704 is pulled back to its position, the micro switch 604 is pressed, ensuring that each time the electric unlocking latch is fully engaged, the micro switch 604 sends a signal to the main board 601 to determine that the latching tongue 704 is fully engaged. Figure 17 and Figure 18 As shown, at this time, the motherboard 601 will not continuously send a signal to the drive motor 602. The drive motor 602 exerts force to achieve the low power consumption requirement. At the same time, the deadbolt limit plate 10 returns to its original position under the action of the deadbolt limit torsion spring. After power failure, the oblique tongue 704 returns to its original position under the action of the oblique tongue reset torsion spring. Figure 19 As shown.

[0045] The entire electric unlocking action does not drive the lock cylinder's opening and closing parts; the electric and lock cylinder opening and closing structures are equipped with a free-spinning angle to achieve complete separation.

[0046] (3) The process of unlocking by holding the handle, such as Figures 20 to 24 : The handle, through the square hole, drives the handle head 401 to rotate clockwise against the elastic force of the handle return torsion spring 404, forcing the main lock rack 1 to move to the right along the main lock guide post 901 and the main lock guide hole 102. This forces the top and bottom hook limiting pieces 10 to move upward against the elastic force of the top and bottom hook limiting torsion spring 1001. At this time, the top and bottom hook limiting pieces 10 disengage from the top and bottom hook locking positions 303 on the lower top and bottom hooks 3. At this time, the first S-groove 101 on the main lock rack 1 forces the main tongue positioning post 801 riveted to the main tongue assembly 8 to move synchronously along the first S-groove 101 on the main lock rack 1, the lower top and bottom hooks 3 along the second S-groove 301, and the upper top and bottom hooks 2 along the third S-groove 201 to complete the retraction of the cylindrical tongue. Figure 21 and Figure 22 As shown; simultaneously, the handle lever 401 forces the handle lever 402 to rotate around the handle positioning post 403, forcing the latch release plate 703 to overcome the elastic force of the latch return torsion spring and move backward to complete the latch retraction action and unlock. At the same time, the top and bottom hook limit plate 10 returns to its original position under the action of the top and bottom hook limit torsion spring 1001, as shown. Figure 23 As shown, after the unlocking action is completed without force, the handle lever 401 returns to its original position under the elastic force of the handle return torsion spring 404; the latch bolt 704 returns to its original position under the elastic force of the latch bolt return torsion spring, as shown. Figure 24 As shown.

[0047] After the electric lock is engaged, the lever will not drive the lock cylinder to operate the opening and closing parts; the lever unlocking mechanism and the lock cylinder opening and closing mechanism have a free-spinning angle to achieve complete separation.

[0048] (4) The locking process of the lock cylinder, such as Figures 25 to 26 : The indoor knob / outdoor key rotates counterclockwise, causing the lock cylinder's direct drive gear 501, drive spur gear 502, drive double-layer gear 503, end spur gear 505, and end semi-disengaged spur gear 506 to rotate synchronously. Figure 26 Simultaneously, the main lock rack 1 is driven to move to the left along the main lock guide post 901 and the main lock guide hole 102 via a gear and rack transmission, forcing the deadbolt limit plate 10 to move to the left against the elastic force of the deadbolt limit torsion spring 1001. At this time, the main lock rack 1 forces the main tongue positioning post 801 riveted to the main tongue assembly 8 to move downwards along the first S groove 1011 on the main lock rack 1, the lower deadbolt 3 along the second S groove 301, and the upper deadbolt 2 along the third S groove 201 to complete the locking action. At this time, the deadbolt limit plate 10 returns to its original position under the action of the deadbolt limit torsion spring 1001 and simultaneously locks the deadbolt locking position 303 on the lower deadbolt 3 to achieve the locking effect (the principle is the same). Figures 7 to 11 same).

[0049] Locking the lock cylinder will not drive the gears inside the motor gearbox; after the electric opening and closing action is completed, the motor gearbox assembly is in an idle state.

[0050] (5) The process of unlocking the lock cylinder, such as Figures 27 to 28 : The indoor knob / outdoor key rotates clockwise, causing the lock cylinder's direct drive gear 501, drive spur gear 502, drive double-layer gear 503, end spur gear 505, and end semi-disengaged spur gear 506 to rotate synchronously. Figure 28Simultaneously, through a gear and rack transmission, the main lock rack 1 moves to the right along the main lock guide post 901 and the main lock guide hole 102, forcing the top and bottom hook limiting plate 10 to overcome the elastic force of the top and bottom hook limiting torsion spring 1001 and move upward. At this time, the top and bottom hook limiting plate 10 disengages from the top and bottom hook locking position 303 on the lower top and bottom hook 3. At this time, the first S groove 101 on the main lock rack 1 forces the main tongue positioning post 801 riveted to the main tongue assembly 8 to move upward along the first S groove 101 on the main lock rack 1. Hook 3 retracts synchronously along the second S-groove 301 and upper hook 2 retracts synchronously along the third S-groove 201. At the same time, the latching pin 105 riveted to the main lock rack 1 forces the latching plate 701 to rotate around the latching pin 904, and simultaneously forces the latching guide plate 702 to move backward. At the same time, the latching guide plate 702 pulls back the latching separation plate 703 and the latching tongue 704 to complete the unlocking action. After the force is removed, the latching tongue 704 returns to its original position under the action of the latching tongue return torsion spring (the principle is the same). Figures 15 to 19 same).

[0051] Unlocking the lock cylinder will not drive the gears inside the motor gearbox; after the electric opening and closing action is completed, the motor gearbox assembly is in an idle state.

[0052] Advantages of the lock body structure of this utility model 1) The lock body structure of this utility model realizes the complete separation of the electric drive switch lock from the lock cylinder drive switch lock; that is, the electric opening / closing will not drive the lock cylinder opening / closing related structural components; the lock cylinder opening / closing will not drive the motor gearbox related structural components, thus avoiding the inability to open / close the lock with the key / lock cylinder due to electronic / motor abnormalities.

[0053] 2) The lock body structure of this utility model achieves separation from the lock cylinder without changing the user's operating habits when using the lock cylinder to open / close the lock. Clockwise rotation of the lock cylinder unlocks the lock, and counterclockwise rotation locks it.

[0054] 3) Existing lock body structures can only fix the lock cylinder from the side of the lock body with screws, which cannot meet the installation requirements of different scenarios or doors. The lock body structure of this utility model is designed to fix the lock cylinder from both the front and the side of the lock body, meeting the installation needs of customers in different scenarios.

[0055] 4) Existing lock body structures rely on the lock cover 13 to hold down the internal structural components. When the lock cover 13 is opened, these internal components are prone to disintegration, making it difficult for on-site installers or after-sales personnel to promptly identify and resolve the problem. The lock body structure of this invention is designed with the stability of the internal components in mind. Even with the lock cover 13 open, it can still operate normally and is less prone to disintegration, facilitating timely detection and resolution of problems by on-site installers and after-sales personnel.

[0056] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
