Description

Technical Field

[0001] This invention specifically relates to door locks, and more particularly to door locks that integrate key-operated and motor-operated automatic opening mechanisms. Background Technology

[0002] Door locks are a common device in our lives. In normal life, we use door locks every day, whether we are going out or coming in.

[0003] At the same time, door locks are also an important device to ensure the safety of our home life. Door locks play a role in protecting our home safety and preventing others from illegally entering our home and other private spaces.

[0004] Since door locks are used very frequently, whether going out or coming in every day, their design must be very convenient so that they don't take up too much of our time and energy during high-frequency use.

[0005] Among existing door lock technologies, mechanical locks that use keys still dominate the market. The advantages of key-operated locks are: 1. Reliable opening; the lock structure is relatively simple, and mechanical failures are generally rare. 2. Low manufacturing and production costs, making them inexpensive to purchase.

[0006] However, mechanical keys are increasingly unsuitable for people's demands for a high-quality modern life, mainly because: 1. Keys are relatively cumbersome to use, requiring the insertion of a key and manual turning. 2. Keys must be carried at all times when leaving home, but in reality, people often forget their keys, resulting in being locked out. 3. Because mechanical keys are inconvenient, they are unsuitable for the elderly and children.

[0007] Therefore, in order to solve the above problems, smart locks have appeared on the market. They can be opened by fingerprints, iris scans, chip cards, passwords, etc., which greatly saves people's time and steps in unlocking, and can be unlocked without carrying a key.

[0008] However, the smart locks currently on the market have the following problems:

[0009] 1. The structure of smart locks is relatively complex, which makes the production cost of smart locks relatively high.

[0010] 2. The smart lock opens the door by driving the bolt with a motor. However, sometimes the motor drive may malfunction, such as when the battery is dead, the motor drive has a mechanical failure, or the power connection is broken.

[0011] Therefore, it is necessary to provide a door lock with a simpler structure, lower production costs, and the ability to be opened with a key in case of motor drive failure or other situations, namely a door lock that integrates key opening and automatic motor opening. Summary of the Invention

[0012] To address the aforementioned issues, ensure the safety and peace of mind of electronic lock users, and make the lock simple in structure, low in production cost, reliable in structure, and secure, the purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated intelligent lock core that combines automatic motor opening and key opening.

[0013] The present invention relates to an integrated smart lock body that combines automatic motor opening and key opening, comprising a lock shell, the inner surface of which is a main mounting plate. A lock cylinder lever, a drive motor, and a main bolt are disposed on the main mounting plate. The front end of the main bolt extends outward from the lock shell, and the rear end is the tail end of the main bolt.

[0014] A cylinder latch is located at the end of the main bolt near the cylinder derailleur. The cylinder latch engages with the cylinder derailleur to push the main bolt back and forth within the lock housing. The cylinder latch has at least one protrusion that engages with the cylinder derailleur.

[0015] It also features a movable motor mounting plate, which is parallel to the main mounting plate and the main lock tongue, with the tail end of the main lock tongue intersecting the motor mounting plate.

[0016] The motor mounting plate is divided into a left side and a right side with the extension and retraction direction of the main lock tongue as the central axis. A drive motor and a dial wheel driven by the drive motor are fixed on the right side of the motor mounting plate. A dial tooth is provided on the tail end of the main lock tongue. The dial wheel and the dial tooth mesh together to drive the extension and retraction of the main lock tongue.

[0017] The left edge of the motor mounting plate is the lock cylinder paddle pushing edge. The lock cylinder paddle pushing edge engages with the lock cylinder paddle. The left and right movement of the motor mounting plate is caused by the lock cylinder paddle pushing the motor mounting plate, which causes the paddle wheel to disengage from the paddle teeth.

[0018] The integrated smart lock body that combines automatic motor opening and key opening, as described above, is further explained as follows: the lock cylinder dial is composed of several first notches opened at the tail end of the main lock tongue. The first notches are distributed on the left side of the tail end of the main lock tongue in a direction parallel to the central axis, and the lock cylinder dial engages with the first notches.

[0019] The aforementioned integrated smart lock body, combining automatic motor opening and key opening, is further described as follows: a damping positioning device is fixed at the end of the main lock tongue. This damping positioning device includes several second notches at the end of the main lock tongue, distributed parallel to the central axis on the left side of the end of the main lock tongue, with raised arc surfaces connecting the notches, and spring pins installed within the notches.

[0020] The aforementioned integrated smart lock body combining automatic motor opening and key opening is further described as follows: the spring pin is vertically mounted on the damping plate, the damping plate is parallel to the main mounting plate, and the damping plate has a damping groove perpendicular to the extension and retraction direction of the main bolt. A damping pin perpendicular to the main mounting plate is provided, and the damping groove is fitted onto the damping pin. A damping spring is provided on the damping plate.

[0021] The aforementioned integrated smart lock body combining automatic motor opening and key opening is further described as follows: the motor mounting plate is positioned between the main bolt and the main mounting plate. The sliding edge is a concave arc, with the center of rotation of the lock cylinder lever as its center.

[0022] The integrated smart lock body that combines automatic motor opening and key opening, as described above, is further explained as follows: a small latch and a small latch fork are also provided on the right side of the main mounting plate. The small latch fork is fitted onto the fork shaft in the middle and rotates around the fork shaft. The fork shaft is vertically set on the main mounting plate.

[0023] The small latch fork is equipped with a fourth protrusion and a fifth protrusion, and the fourth protrusion engages with the tail of the small latch.

[0024] A push rod is installed on the main bolt, perpendicular to the direction of extension and retraction of the main bolt. One end of the push rod engages with the fifth protrusion, and the other end engages with the lock cylinder lever. A first cam is installed on the main bolt, and the first cam engages with the middle part of the push rod.

[0025] The aforementioned integrated smart lock body, combining automatic motor opening and key opening, is further described as follows: the dial tooth is a first rack, and a second rack is movably mounted on the first rack, with the first and second racks arranged side by side. The dial wheel is a gear, simultaneously meshing with both the first and second racks. The front end of the second rack meshes with a first cam.

[0026] The integrated smart lock body with automatic motor opening and key opening, as described above, is further explained as follows: The motor mounting plate is equipped with a first return spring, which returns the motor mounting plate to the main bolt, keeping the dial wheel and dial teeth engaged. The tail of the small bolt is equipped with a second return spring, which pushes the small bolt towards the lock housing, keeping the small bolt in the locked state. The push rod is equipped with a third return spring, which keeps the push rod in the ready-to-engage state with the lock cylinder dial. The second rack is equipped with a fourth return spring, which keeps the front end of the second rack separated from the first cam.

[0027] A main pin is vertically mounted on the main mounting plate, and a first slide groove is provided on the main lock tongue. The first slide groove is parallel to the extension and retraction direction of the main lock tongue and is fitted onto the main pin.

[0028] The motor mounting plate is provided with a second slide groove, which is perpendicular to the extension and retraction direction of the main locking tongue and is fitted onto the main pin.

[0029] A third pin is provided on the main latch, and a third slide groove is provided on the push rod, with the third slide groove perpendicular to the extension and retraction direction of the main latch. The third slide groove is fitted onto the third pin, causing the push rod to move perpendicular to the extension and retraction direction of the main latch.

[0030] A fourth pin is provided on the first rack, and a fourth groove is provided on the second rack, with the fourth groove parallel to the direction of extension and retraction of the main latch. The fourth groove is fitted onto the fourth pin, causing the second rack to move parallel to the direction of extension and retraction of the main latch.

[0031] The aforementioned integrated smart lock body, combining automatic motor opening and key opening, is further described as follows: a protrusion is provided in the middle of the push rod, and a first cam extends into the protrusion to engage. The drive motor is connected to the dial wheel via a gear mechanism to transmit power. The first and second racks are located on the side of the main lock tongue near the dial wheel at the tail end, parallel to the direction of extension and retraction of the main lock tongue. The first rack has a tooth gap near the first cam.

[0032] The aforementioned integrated smart lock body combining automatic motor opening and key opening is further described as follows: the dial tooth is a third protrusion, and at least one third protrusion is arranged side-by-side on the main bolt. The dial wheel is a second cam, which engages with the third protrusion and the first cam.

Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will describe them in conjunction with specific embodiments and corresponding appendices. Figure 1-11 The technical solution of the present invention will be clearly and completely described.

[0050] The present invention includes a lock shell, the inner surface of which is a main mounting plate 1; a lock cylinder lever 5, a drive motor 6, and a main lock tongue 2 are provided on the main mounting plate; the front end of the main lock tongue is the main lock tongue end that extends outward from inside the lock shell, and the rear end is the main lock tongue tail end 3.

[0051] The main bolt is a flat block, generally rectangular. When locked, the part that extends out of the lock case is the main bolt end, and the corresponding rear end is the main bolt tail end. For ease of description, the line connecting the head end to the tail end of the main bolt is the central axis, which is divided into the left end and the right end of the main bolt. The part closer to the lock cylinder lever 5 is the left end of the main bolt.

[0052] refer to Figure 2 On the left side of the rear end of the main bolt of the present invention, a lock cylinder aperture 7 is provided to engage with the lock cylinder paddle. The lock cylinder aperture is a notch directly opened on the left side of the rear end of the main bolt. There are at least two notches, and the edges of the notches form protruding parts. The lock cylinder paddle drives the protruding parts to paddle the large bolt, so that the large bolt extends and retracts.

[0053] refer to Figure 4 To enhance the sense of position when opening the lock with a key, allowing the key to feel its positioning with each turn, remember the number of turns, and ensure the key is turned to the correct release position (the key cannot be removed if the lock cylinder is not turned to the correct position), a damping positioning device is required. This device could be a row of notches at the end of the main bolt, with damping spring pins installed inside. However, since other components and devices are located on both sides of the invention, there are limited spaces for adding notches. Therefore, this invention features a protruding strip-shaped structure parallel to the central axis of the main bolt on its surface (back side). A second notch 14 is then created on this strip-shaped structure, distributed parallel to the central axis, with raised arc surfaces connecting the notches to facilitate smoother sliding of the spring pin between them.

[0054] A spring pin is vertically mounted on the damping plate, which is parallel to the main mounting plate. A damping groove 16 is provided on the damping plate, perpendicular to the extension and retraction direction of the main latch. A damping pin is provided perpendicular to the main mounting plate, and the damping groove is fitted onto the damping pin. A damping spring is provided on the damping plate, which is used for the damping plate to reset by pulling the spring pin into the second notch. One end of the resistance spring is hooked onto the damping plate, and the other end is hung on the main mounting plate at an appropriate position.

[0055] refer to Figure 1 , Figure 2 The motor mounting plate 4 is located between the main lock tongue 2 and the main mounting plate 1. The tail end 3 of the main lock tongue covers the motor mounting plate. With the extension and retraction direction of the main lock tongue as the central axis, the motor mounting plate is divided into the left side of the motor mounting plate and the right side of the motor mounting plate.

[0056] To enable the motor mounting plate to move horizontally on the main mounting plate, a moving track needs to be installed on the motor mounting plate. There are various ways to install this track, such as using a slide rail between the motor mounting plate and the main mounting plate, or using a track groove to allow the motor mounting plate to move on the main mounting plate. However, using a track or track groove method makes processing difficult and is inconvenient for installation. Therefore, this invention uses a method of setting a pin on the main mounting plate and creating a slot in the motor mounting plate. Specifically, a second sliding groove 9 is provided on the motor mounting plate. The second sliding groove is an elongated hole on the motor mounting plate, with the slot direction perpendicular to the central axis and a slot length of 10-15 mm, allowing the motor mounting plate to move 10-15 mm left and right. The width of the second sliding groove is approximately equal to the diameter of the main pin and is at least a clearance fit. To prevent the motor mounting plate from rotating during operation, at least two to three second slides are provided on the motor mounting plate, and correspondingly multiple pins are provided on the main mounting plate to prevent the motor mounting plate from deflecting during movement. The second slides are positioned on the motor mounting plate to avoid collisions or conflicts with other parts, so any appropriate location on the motor mounting plate can be chosen for the second slides.

[0057] refer to Figure 3 The translational movement of the motor mounting plate is driven by the lock cylinder lever 5. On the right side of the motor mounting plate, there is a push edge 12. The push edge is an arc that is recessed towards the center of the motor mounting plate on the right side. The center of the arc is centered on the rotation center of the lock cylinder lever. The lock cylinder lever is similar to a rotating cam. When the lock cylinder lever rotates to the push edge, it pushes the arc-shaped push edge 12, causing the entire motor mounting plate 4 to move 50-10 mm to the right.

[0058] refer to Figure 2 The right side of the motor mounting plate is used to mount the drive motor 6, the speed gear 29, and the dial wheel. The drive motor uses a transmission mechanism such as the speed gear to transmit driving force to the dial wheel. Moving the motor mounting plate can simultaneously move the drive motor, speed gear, and dial wheel on the motor mounting plate.

[0059] The drive motor is a small 12V-24V motor. The motor output shaft is a worm gear, which drives the gear set. Through gear shifting and power transmission, the dial wheel rotates. The drive motor is located in the lower right corner of the motor mounting plate, with the output worm gear facing left. A worm gear meshes with the worm gear, and through the worm gear and other gears, the rotational speed reaches the dial wheel at less than 30 revolutions per minute, allowing the dial wheel to provide greater torque. In this invention, the drive motor, gear shifting gears, and dial wheel are all arranged near the left edge of the motor mounting plate, with the dial wheel positioned at the front edge of the motor mounting plate.

[0060] The motor mounting plate is a metal plate with a thickness of 1-2 mm. To enable left and right movement of the motor mounting plate, a first return spring 11 is also required. The first return spring can be configured in various ways, such as a compression spring on the right side of the motor mounting plate, or a torsion spring on the main pin shaft or other locations, in conjunction with a hook on the motor mounting plate. All these methods can drive the motor mounting plate to return to its leftward position. Because the left side of the lock housing in this invention has a relatively large clearance, and the working stability of the tension spring is relatively high, the first return spring in this invention is a tension spring. A hook is provided on the left side of the motor mounting plate. When the lock cylinder lever stops pushing the motor mounting plate, the tension spring is used to return the motor mounting plate to its leftward position.

[0061] The front end of the main bolt 2 is the bolt tip that extends outward from inside the lock housing, and the rear end is the bolt tail end 3. To enable the main bolt to extend and retract within the lock housing, a moving track needs to be provided on the main bolt. There are various ways to set the moving track, such as setting a slide rail between the main bolt and the main mounting plate. Using a slide rail or track groove, the main bolt can extend and retract within the lock housing. However, using a track or track groove increases the processing difficulty and makes installation inconvenient, increasing the overall production cost. Therefore, this invention uses a pin on the main mounting plate and a slot at the bolt tail end. Specifically, a first sliding groove 8 is provided on the bolt tail end. The first sliding groove is an elongated hole on the bolt tail end, with the groove direction parallel to the central axis of the main bolt (i.e., the groove direction is front-to-back). The groove length is greater than or equal to the length of the main bolt that finally extends out of the lock housing. In this invention, it is 25-30 mm. The width of the first sliding groove 8 is equivalent to the diameter of the main pin and is at least a clearance fit.

[0062] Therefore, the first slide groove 8 and the second slide groove 9 of the present invention are both fitted onto the main pin shaft. Ultimately, this achieves the main locking tongue 2 moving back and forth parallel along the main pin shaft 13, and the motor mounting plate 4 moving left and right parallel along the main pin shaft.

[0063] The motor mounting plate has an inwardly recessed arc (pushing edge) on the right side. During operation, the lock cylinder lever 5 will slide along this arc edge. Because the lock cylinder lever has a certain thickness, and the main bolt is superimposed on the motor mounting plate, it is necessary to prevent the lock cylinder lever from colliding with the tail end 3 of the main bolt when pushing the motor mounting plate. This leaves the rear end of the main bolt empty, providing working rotation space for the lock cylinder lever.

[0064] The thickness of the main lock tongue end of this invention is 10mm, the length is 25mm, and the width exceeds 50mm. The main lock tongue end can be a single piece or a three-pronged structure. The thickness of the main lock tongue tail end is 1.5-3mm, and the length is 60-80mm.

[0065] refer to Figure 7 , Figure 8 In this invention, the small latch 23 is located on the right side of the main mounting plate. The small latch fork 24 is L-shaped, with its middle part fitted onto the fork shaft and rotating around the fork shaft. The fourth protrusion 25 on the small latch fork extends to the right, with its front end 30mm from the center of the fork shaft, and engages with the tail of the small latch. The fifth protrusion 22 extends forward, with its front end 30mm from the center of the fork shaft, and engages with the right end of the push rod 17. The fork shaft of this invention can be integrated with the door handle. The door handle drives the small latch fork 24 to rotate, thus opening the small latch. Therefore, it is possible to open the door by using the door handle to open the small latch while the main latch is already open.

[0066] The push rod 17 of this invention spans the left and right sides of the large latch and is movably mounted on the large latch 2. Its direction of movement is perpendicular to the extension and retraction direction of the large latch, i.e., left-right translation. To achieve this left-right translation of the push rod, a moving track needs to be provided on the push rod or the main latch. There are various ways to set up the moving track, such as setting a slide rail between the main latch and the push rod. Using a slide rail or track groove, the push rod can achieve reciprocating motion on the main latch. However, using a track or track groove increases the processing difficulty and installation inconvenience, increasing production costs. This invention provides a third pin 18 on the large latch and a third sliding groove 20 on the push rod. The third sliding groove is fitted onto the third pin, and its length is 15mm, with the groove direction perpendicular to the central axis of the large latch. To prevent the push rod from deflecting during translation, this invention provides two third pins in the direction of push rod movement.

[0067] The left end of the push rod engages with the lock cylinder paddle 5, and the right end engages with the fourth protrusion 25. When the lock cylinder paddle rotates, it will push the push rod to the right. During the translation, it will push the small lock tongue fork 24 to rotate, thereby transmitting the rotational power of the lock cylinder paddle to the small lock tongue, causing the small lock tongue to retract backward.

[0068] In order to make the lock cylinder paddle hit the left side of the push rod when it rotates, and the right side of the push rod hit the fifth protrusion, a collision rod can be added to each of the left and right ends of the push rod, so that the push rod is generally U-shaped and the total length of the push rod is 50mm, which is made of sheet metal.

[0069] A first cam 19 is provided on the main latch, which engages with the middle part of the push rod 17. When the first cam rotates, it can push the push rod to the right. A recess is provided in the middle of the push rod, and the first cam 19 extends into the recess to form engagement.

[0070] In order to drive the rotation of the first cam and enable the shift wheel to drive the shift teeth to extend and retract the main latch, the present invention provides the following two examples of shift wheel and shift tooth designs:

[0071] refer to Figure 5 , Figure 6 , Figure 11 Example 1 of the design of the shift wheel and shift teeth: The shift wheel is a gear 28, and the shift teeth are racks (first rack 34). The first rack 34 is located on the right side of the tail end 3 of the large latch, and its length is 30-35mm. Parallel to the first rack is the second rack 30, which is movably mounted on the first rack. The direction of movement of the second rack 30 is parallel to the extension and retraction direction of the large latch, and the distance of its parallel back-and-forth movement is 15mm. The length of the second rack is longer than that of the first rack, reaching 40-45mm; the tail of the second rack is aligned with that of the first rack, and the front of the second rack extends by 10-15mm. A seventh protrusion 29 is provided at the front end of the second rack, meshing with the first cam 19. When the second rack moves towards the tail relative to the large latch, the seventh protrusion 29 pulls the first cam to rotate. In order to enable the second rack to move independently relative to the first rack, a fourth pin 32 is provided on the first rack, and a fourth slide groove 31 is provided on the second rack. The fourth slide groove is parallel to the extension and retraction direction of the main locking tongue. The fourth slide groove is sleeved on the fourth pin, and a fourth return spring 33 is provided on the second rack.

[0072] refer to Figure 9 , Figure 10 Example 2 of dial and gear design:

[0073] The shift tooth is a protrusion (third protrusion 26), the third protrusion 26 is located on the right side of the tail end of the large lock tongue, and at least 2-3 third protrusions are arranged side by side in the front-back direction; the shift wheel is a second cam 27, which meshes with the third protrusion 26 and the first cam.

[0074] The working principle of this invention is as follows:

[0075] The unlocking / closing method of the present invention includes two schemes: automatic unlocking / closing via a drive motor and unlocking / closing via a key.

[0076] 1. Automatic opening / closing of the drive motor:

[0077] The drive motor is connected to the fingerprint recognition system, ultrasonic remote key, facial recognition system, and password system outside the door. When it receives the unlock / close command, the drive motor starts to rotate.

[0078] Status: The large latch 2 is retracted inside the lock case, the small latch 23 extends outside the lock case under the support of the second return spring 21, the dial wheel and the dial tooth are in a meshing state, and the lock cylinder dial 5 is in a separated state from the push rod 17, the lock cylinder dial, and the push edge 12.

[0079] Locking process: The motor rotates clockwise, transmitting power to the dial wheel via the gearbox. As the dial wheel rotates, it engages the gear teeth, causing the large latch to move forward and extend from the lock housing. (Under this principle, if the dial wheel and gear teeth use a gear and rack design, then gear 28 drives rack 34, pushing the large latch forward. If the dial wheel and gear teeth use a second cam 27 and a third cam 26 design, the dial wheel, during rotation, engages the first third cam at the front, causing the large latch to extend forward a certain distance. Then the dial wheel continues rotating, disengaging from the first third cam, and after another full rotation, engages the second third cam, causing the large latch to extend forward a further distance.)

[0080] The bolt extends forward, completing the locking process. At this time, the push rod, first cam, first rack, and second rack (or second cam and third protrusion) set on the bolt are all driven forward by the bolt.

[0081] Unlocking process: The motor reverses (counter-clockwise), transmitting power to the dial wheel via the transmission gear 10. As the dial wheel rotates, it engages the gear teeth, causing the bolt to move backward and retract from the lock case. (Under this principle, if the dial wheel and gear teeth use a gear and first rack design, the gear drives the first rack, pushing the bolt backward; if the dial wheel and gear teeth use a second cam and third protrusion design, the dial wheel, during rotation, engages the second and third protrusions at the rear, causing the bolt to retract a short distance. Then the dial wheel continues rotating, disengaging from the second and third protrusions, and after another full rotation, engages the first third protrusion, causing the bolt to retract a further distance.) The bolt is then unlocked.

[0082] At this time, the push rod 17, the first cam 19, the first rack 34, and the second rack 30 (or the second cam 27 and the third protrusion 26) set on the large latch are all driven to move backward by the large latch. After moving to the corresponding position, the right end of the push rod 17 engages with the fifth protrusion 22. 1. When the gear is a gear and the first rack is a tooth with a second rack on it, the continued rotation of the gear causes the first rack to continue moving backward. Since the front tooth of the first rack is empty, at this position, the gear 28 disengages from the first rack 34, the large latch stops moving, and the gear 28 engages with the second rack 30 alone, driving the second rack to continue moving backward. Therefore, the second rack, relative to the large latch, moves and actuates the first cam 19, which is also on the large latch. The first cam actuates the push rod to the right, pushing the small latch fork, which in turn pushes the small latch into the lock case, unlocking the small latch and completing the unlocking process. 2. When the dial wheel is in the second cam position and the shift tooth is in the third protrusion position, the large latch retracts, causing the first cam 19 on the large latch to reach the engagement position with the dial wheel. After the dial wheel continues to rotate, it engages with the first cam and shifts the first cam. The first cam shifts the push rod to the right, pushing the small latch shift fork 24, which in turn pushes the small latch into the lock case, unlocking the small latch. The unlocking process is completed.

[0083] II. Key to open / close the lock:

[0084] Status: The large latch is retracted inside the lock case, the small latch is extended outside the lock case, the shift wheel and shift teeth are engaged, and the lock cylinder shift plate, push rod, lock cylinder shift hole, and push edge are disengaged.

[0085] Locking process: The key is inserted into the lock cylinder and turned, causing the lock cylinder lever to rotate counter-clockwise. As it rotates, the lever engages with the push-side and pushes the motor mounting plate to the right. This causes the drive motor, transmission gears, and dial wheel on the motor mounting plate to move to the right, disengaging the dial wheel from the teeth. The lock cylinder lever continues to rotate, engaging with the lock cylinder latch. By actuating the protrusion on the latch, it drives the main bolt, which in turn pushes the tail end of the main bolt, causing it to extend slightly outwards from the lock housing. After the lock cylinder lever rotates another full turn, the same process drives the motor mounting plate and the second protrusion, causing the main bolt to extend slightly outwards from the lock housing again, completing the locking process.

[0086] Unlocking Process: The lock cylinder lever rotates clockwise. During rotation, the lever reaches the engagement point with the pusher edge and pushes the motor mounting plate to the right. This causes the drive motor, transmission gear, and shift wheel on the motor mounting plate to move to the right, disengaging the shift wheel from its engagement with the shift teeth. The lock cylinder lever continues to rotate, engaging with the lock cylinder latch. By actuating the protrusion on the latch, it drives the main bolt, causing it to retract slightly into the lock housing. After the lock cylinder lever completes one full rotation, the same process pushes the motor mounting plate and lock cylinder latch, causing the main bolt to retract further into the lock housing, completing the main bolt unlocking process. When the main bolt reaches its final position, it moves the push rod on the main bolt backward. The collision rod at the left end of the push rod engages with the lock cylinder lever. When the lock cylinder rotates again, it pushes the push rod to the right, which in turn rotates the small bolt fork, opening the small bolt. The unlocking process is complete.

[0087] The above embodiments are used to explain and illustrate the present invention, but not to limit the present invention. Any modifications and changes made to the present invention within the spirit and scope of the claims shall fall within the protection scope of the present invention.
