Description

Technical Field

[0001] This utility model relates to the field of lock technology, specifically to an electronic fully automatic lock body. Background Technology

[0002] The lock body includes a bolt with an angled face. This angled bolt is directional, so if reverse installation is required, the lock body usually needs to be disassembled, the bolt replaced, or the bolt rotated 180°, making installation cumbersome. Furthermore, existing lock bodies require manual unlocking, typically necessitating the user's use of a key or other tools. This is inconvenient when hands are occupied or during inconvenient times (such as at night or in bad weather). Manually unlocked lock bodies cannot offer smart features such as integration into smart home systems, remote control and monitoring, or even automatic operation based on user habits. While traditional mechanical locks have their unique security mechanisms, technological advancements have led to the emergence of advanced unlocking techniques (such as key-bumping and lock-picking), compromising security. For the elderly and children, using traditional manual locks can be challenging, especially complex designs or those requiring considerable force to open.

[0003] For example, patent CN117145313A, entitled "A Bi-directional Flip Locking Mechanism and Lock Body," discloses a bi-directional flip locking mechanism and lock body. The bi-directional flip locking mechanism includes: a lock housing; a latch plate slidably disposed on the lock housing; a latch bolt rotatably mounted on the latch bolt plate, the latch bolt having a first working surface and a second working surface, the first and second working surfaces being inclined and located on opposite sides of the latch bolt; the latch bolt also having a first sliding groove and a second sliding groove, the first sliding groove being inclined to the second working surface, and the second sliding groove being inclined to the first working surface; a latch bolt plate reset elastic element; and a locking block for sliding engagement with the first or second sliding groove. This application, through a rotatable latch bolt, combined with a locking block and the first and second working surfaces, first and second sliding grooves of the latch bolt, enables relatively convenient switching between two installation directions without disassembling or replacing the latch bolt. Utility Model Content

[0004] Technical problem to be solved by the utility model

[0005] The technical problem to be solved by this utility model is to provide an electronic fully automatic lock body with a built-in geared motor and detection switch. It has multiple functions, a compact lock body, low overall power consumption, fast speed and strong unlocking force. Furthermore, through the rotatable flip tongue, it is possible to switch between two installation directions in a relatively convenient way without removing or replacing the tongue.

[0006] Technical solution

[0007] To solve the above problems, the technical solution provided by this utility model is as follows:

[0008] An electronic fully automatic lock body, including

[0009] The drive structure includes a geared motor, a motor gear, and a cam gear connected by transmission. The cam gear is fitted with a square tongue pawl and a square steel pawl. The inner sides of the cam gear and the square tongue pawl are respectively provided with inner ring protrusion one and inner ring protrusion two for abutting cooperation. The side of the cam gear is provided with protrusions.

[0010] The flip tongue structure includes a flip tongue with a bidirectional inclined surface and a fork slide groove. The flip tongue is hinged to a retractable flip plate. The flip plate is equipped with a micro switch. The fork slide groove is equipped with a locking block. The locking block is a lever structure and is driven by the protrusion to engage and lock with the slide groove of the fork slide groove.

[0011] The trigger tongue structure includes a retractable trigger tongue and a micro switch that is triggered after retraction, and the micro switch is connected to the controller;

[0012] The main bolt structure includes a retractable main bolt, which has a main lock drive groove. The two end walls of the main lock drive groove respectively engage with the extension of the square bolt lever in the corresponding retractable state. A square steel lever with a convex gear is coaxially sleeved. The square steel lever cooperates with the unlocking lever and the lock head lever to control the square bolt lever. The square bolt lever pushes the main bolt to move. The main bolt, the lock head lever, and the unlocking lever are stacked.

[0013] This lock body has a built-in high-performance geared motor and detection switch. With the help of digital communication signals, it controls the operation of the geared motor inside the lock, which drives the gear transmission to make the bolt retract or extend, so as to unlock or lock.

[0014] After the flip-tab is flipped to different directions, it can be locked by the locking block. Without removing the panel or replacing the flip-tab, it is relatively convenient to automatically switch the two installation directions of the lock body.

[0015] The lock features a convex gear, a square latch block, and a square steel lever, all nested together. The main latch, lock cylinder lever, and unlocking lever are stacked, significantly saving space and reducing the lock's size while maintaining optimal functionality. This allows for the manufacture of more compact and refined locks, and also reduces material costs to some extent. The inner sides of the convex gear and square latch block have two abutting inner ring protrusions, and the main latch has a main lock drive groove. The two ends of the main lock drive groove, in their corresponding extension and retraction states, engage with the extension of the square latch block, optimizing the force transmission path and improving the overall efficiency of the drive structure. This means the lock can achieve fast and stable locking and unlocking operations with less energy consumption. The compact design reduces gaps between moving parts, lowering the risk of loosening due to vibration or prolonged use, thus enhancing the lock's stability and reliability. The smaller lock size allows it to adapt to a wider variety of door types and installation environments, increasing the product's applicability.

[0016] Square steel levers are used for mechanical unlocking. They can be used to move square steel blocks through a transmission mechanism to unlock the main lock tongue, avoiding the risk of not being able to open the door if electronic components malfunction.

[0017] Trigger tongue function: The locking block locks and unlocks the flip tongue. Method 1: When the trigger tongue is retracted, the motor drives the gear, and the gear drives the locking block to lock and unlock the flip tongue. Method 2: When the trigger tongue is extended, the locking block is unlocked through the structural transmission of the trigger tongue bracket, and the locking block is locked when the trigger tongue is retracted.

[0018] Optionally, the output end of the geared motor is provided with a bevel gear, and the end face of the motor gear mates with the bevel gear.

[0019] By using bevel gears, the direction of force can be changed within a compact space, making the entire drive structure more compact and contributing to a further reduction in the overall size of the lock body. Bevel gears effectively convert the rotational power of the geared motor into a power form suitable for the internal mechanical structure of the lock body (such as cam gears, square latch blocks, etc.), ensuring efficient force transmission and thus improving the overall system efficiency. Bevel gears typically possess good wear resistance and strength, maintaining stable performance over long-term use, reducing functional degradation caused by wear, and enhancing the reliability and durability of the lock body.

[0020] Optionally, the rotating part of the square tongue block extends with a micro-motion trigger protrusion, and a micro switch is provided at the same plane height as the square tongue block and cooperates with the micro-motion trigger protrusion to generate a signal.

[0021] When the latch block moves, the micro-trigger protrusion touches the microswitch, generating an electrical signal. This signal can be used to accurately determine the position of the latch block (e.g., fully extended or retracted). By monitoring the latch block's state, the system can automatically execute corresponding actions, such as stopping the motor when the door is correctly locked, or adjusting the driving force and speed based on the actual position during unlocking, thereby improving the overall intelligence of the lock body. If any problems occur, such as the latch jamming and malfunctioning, the system can quickly locate the problem based on the information provided by the microswitch, simplifying maintenance and troubleshooting. Based on the accurate perception of the latch block's position, the system can more efficiently manage the geared motor's operating cycle, avoiding unnecessary energy consumption and helping to extend battery life (especially important for battery-powered lock bodies).

[0022] Optionally, the motor gear is connected to a signal gear and a signal controller.

[0023] Signal Gear: By connecting to the motor gear, the signal gear can precisely track the rotation of the motor gear. This allows the system to accurately know when the latch is fully extended or retracted, thus ensuring the accuracy of locking and unlocking operations.

[0024] Signal Controller: The signal controller receives information from the signal gear and makes corresponding control decisions accordingly. For example, when it detects that the latch has fully retracted, the signal controller can command the geared motor to stop operating, avoiding unnecessary energy consumption or mechanical wear.

[0025] Optionally, the unlocking lever is a hinged lever structure, with one end of the unlocking lever overlapping the square lever and the other end overlapping the lock head protrusion of the lock head lever.

[0026] The articulated lever structure effectively converts and amplifies the applied force, allowing for smooth unlocking even with relatively small force inputs. This improves the system's responsiveness and reliability, helps optimize the entire unlocking process, and ensures smooth and accurate execution every time. In the event of a malfunction in the electronic control system or insufficient power, the user can still manually unlock the door lock mechanically, increasing the system's security and availability. This provides users with an important backup unlocking method, which is especially crucial in emergency situations.

[0027] Optionally, the locking block is provided with a protrusion, and the protrusion is fitted with an unlocking piece. The unlocking piece is hinged and has two ends with a lever structure. The protrusion limits the unlocking piece at the middle section and drives the unlocking piece to rotate. One end of the unlocking piece overlaps with the flip plate, and the other end of the unlocking piece overlaps with the lock head protrusion of the lock head lever.

[0028] The locking block has a protrusion located in the middle of the unlocking plate to limit its movement and drive the unlocking plate to rotate. This means that when the locking block moves, the protrusion touches and pushes the unlocking plate, causing it to rotate around the hinge point. One end of the unlocking plate contacts the flip plate. When the unlocking plate rotates due to the protrusion, this action is transmitted to the flip plate, causing it to move or change its state. The other end of the unlocking plate is connected to the lock head protrusion on the lock head lever. Thus, the movement of the unlocking plate not only controls the state of the flip plate but also directly affects the position of the lock head lever, thereby influencing the state of the main bolt. The lever structure effectively converts the direction and magnitude of force, allowing a smaller input force (such as the force exerted by the protrusion on the unlocking plate) to produce a larger output effect (such as the movement of the flip plate and lock head lever). This improves the system's efficiency and response sensitivity. At the same time, it also increases the system's redundancy.

[0029] Optionally, the unlocking piece has a bent section in the middle, and the bent section overlaps with the protrusion in a crank-slider structure.

[0030] The bend in the middle of the unlocking piece allows it to form an inflection point at a specific location, which enables more precise control over the movement trajectory of the unlocking piece.

[0031] Alternatively, the trigger tongue may have a bidirectional bevel structure.

[0032] The bidirectional bevel structure means that the trigger tongue can receive and respond to forces from both directions. Whether the door is closed from the inside or the outside, or when it is pushed or pulled from any direction, the trigger tongue can effectively actuate the corresponding microswitch, thus ensuring a stable system response.

[0033] Optionally, the geared motor is positioned close to the transmission structure.

[0034] Placing the geared motor close to the transmission structure helps reduce the overall size of the lock body, making it more compact. By directly aligning the geared motor with the transmission structure, the power transmission path is shortened, reducing energy loss due to long-distance transmission and improving overall efficiency. A shorter power transmission path means a faster response time, which increases the speed at which the lock body completes locking or unlocking operations from receiving a command.

[0035] Optionally, the unlocking paddle is hinged via the main lock pin, the main lock tongue has a straight waist hole, the lock head paddle has an arc waist hole, and the main lock pin passes through the straight waist hole and the arc waist hole.

[0036] The straight bore design allows the master bolt pin to slide within it. This provides a flexible way for the master bolt to move in a straight direction while maintaining mechanical connection with the unlocking lever and lock cylinder lever. This ensures that the extension and retraction of the master bolt is both smooth and accurate. The curved bore, compared to the straight bore, allows for a greater range of angles. This means that when the lock cylinder lever rotates, the master bolt pin can rotate through the curved bore to accommodate the unlocking lever. The lower end of the unlocking lever is hinged to a torsion spring pin, around which the unlocking lever can rotate.

[0037] Beneficial effects

[0038] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0039] The technical solution provided by this utility model improves the intelligence level of locks, significantly enhances their practicality and security, and also has the advantages of small lock body, low overall power consumption, fast speed and strong unlocking force.

[0047] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0048] Example 1

[0049] Combined with appendix Figure 1 An electronic fully automatic lock body includes a panel 3, a bottom shell 1, and a cover plate 2, with the bottom shell 1 and cover plate 2 fixedly attached to the panel 3. The panel 3 has buttons with different functions, supporting multiple unlocking methods, and is electrically connected to a controller. The panel 3 has three holes (upper, middle, and lower) for the flip bolt 4, trigger bolt 5, and main locking bolt 6, respectively. The cover plate 2 is secured with rivets, and a lock hole is located at the bottom of the cover plate 2.

[0050] Combined with appendix Figure 2 The drive structure includes a geared motor 8, a motor gear 15, and a cam gear 13 connected by a transmission. The cam gear 13 is fitted with a square tongue lever 12 and a square steel lever 10. The side of the cam gear 13 has a protrusion 1301. The geared motor 8 is located above the lock body, closely attached to the transmission structure, and is basically horizontal, tilted slightly to the lower right to avoid interference with the baffle of the flip plate 19, which abuts against the upper end of the unlocking plate 18. The output end of the geared motor 8 has a bevel gear, and the end face of the motor gear 15 mates with the bevel gear. A circuit board 20 is located in front of the motor gear 15. Two microswitches 17 are mounted on the circuit board 20. One microswitch 17 detects the extension and retraction of the flip plate 19, thereby detecting the extension and retraction of the flip tongue 4. The other microswitch 17 detects the rotation of the square tongue lever 12. A micro-trigger protrusion extends from the rotating part of the square tongue lever 12. A microswitch 17 is mounted at the same plane height as the square tongue lever 12 and engages with the micro-trigger protrusion to generate a signal. The motor gear 15 is connected to a signal gear 16 and a signal controller. Rotation of the signal gear 16 triggers the signal controller, which detects the rotation of the motor gear 15.

[0051] The flip-tab 4 structure includes a flip-tab 4 with a bidirectional inclined surface and a forked slide groove 401. The bidirectional inclined surface is located on the side of the flip-tab 4 and extends out of the panel 3. The flip-tab 4 can rotate to switch between two installation directions. The bidirectional inclined surface includes a first working surface and a second working surface. When the flip-tab 4 is used in the first installation direction, the first slide groove cooperates with the locking block 14, and the flip-tab 4 can only slide along the length of the first slide groove. At this time, the second working surface is inclined relative to the door frame. When the door is closed, the second working surface cooperates with the door frame. Under the reaction force of the door frame, the flip-tab 4 can slide along the length of the first slide groove and retract into the lock body. When the flip-tab 4 is used in the second installation direction (at this time, the position of the flip-tab 4 has rotated relative to when it is used in the first installation position), the second slide groove can cooperate with the corresponding structure in the lock body. The flip-tab 4 can only slide along the length of the second slide groove. At this time, the first working surface is inclined relative to the door frame. When the door is closed, the first working surface cooperates with the door frame. Under the reaction force of the door frame, the flip-tab 4 can slide along the length of the second slide groove and retract into the lock body. The flip tongue 4 is hinged to a retractable flip plate 19, which is equipped with a micro switch 17. The forklift slide 401 is equipped with a locking block 14. The locking block 14 is a lever structure and is driven by a protrusion 1301 to engage and lock with the slide of the forklift slide 401. The locking block 14 is divided into two sections: the middle section is the hinge point, the right section is a semi-circular arc section, and the left section is a straight section. The arc end engages with the protrusion 1301 with a cam gear 13 for limiting. When the cam gear 13 rotates counterclockwise, the protrusion 1301 pushes the semi-circular arc section upward. Due to the existence of the hinge point, the left section is pressed down and disengaged from the lock of the forklift slide 401. At this time, the flip tongue 4 is in a free state and can rotate left and right.

[0052] The trigger tongue 5 structure includes a retractable trigger tongue 5 and a micro switch 17 that triggers after retraction. Both micro switches 17 are connected to the controller. The trigger tongue 5 is also fixedly connected to a trigger tongue 5 bracket. The top of the trigger tongue 5 bracket has an inclined section that cooperates with the round protrusion on the left end of the locking block 14 for limiting movement. When the trigger tongue 5 touches the door frame and retracts into the lock body, the inclined section and the round protrusion disengage, and the left end of the locking block 14 can engage and lock with the fork slide groove 401. Otherwise, the left end of the locking block 14 is limited by the inclined section and cannot be lifted. The trigger tongue 5 has a bi-directional inclined structure and cannot rotate. However, since both sides of the trigger tongue 5 are inclined, regardless of the installation direction, the trigger tongue 5 can retract into the lock body when it touches the door frame.

[0053] Combined with appendix Figure 2 , 3The main latch 6 structure includes a retractable main latch 6, which is provided with a main lock drive groove. The two end walls of the main lock drive groove respectively engage with the extension of the square latch block 12 in the corresponding retracted state. The groove wall is slightly hooked to fit the extension of the square latch block 12. The middle part of the main lock drive groove is a recessed rectangular semi-groove, and the two ends of the rectangular semi-groove are arc surfaces that extend to the end groove walls. Since the extension of the square latch block 12 needs to rotate to drive the main latch 6 to translate and retract, the shape of the main lock drive groove can still engage with the groove wall and drive the main latch 6 to translate and retract when the extension rotates to the middle of the main lock drive groove, thus avoiding interference.

[0054] Combined with appendix Figure 4 The unlocking lever 11 is a hinged lever structure. One end of the unlocking lever 11 overlaps with the square steel lever 10, and the other end of the unlocking lever 11 overlaps with the lock head protrusion 701 of the lock head lever 7. The square steel lever 10 is coaxially sleeved with a convex gear 13. The square steel lever 10 has a square steel hole 9 in the middle. The square steel lever is used to move the square steel lever block to unlock the main lock tongue 6 through the transmission mechanism. The square lever 10 has an oval-shaped weight-reducing hole and a pointed protrusion on the left side. The pointed protrusion abuts against the upper end of the unlocking lever 11. When the square lever 10 is rotated clockwise, it causes the unlocking lever 11 to rotate counterclockwise. The lower end of the unlocking lever 11 moves the lock head protrusion 701 of the lock head lever 7. The lock head lever 7 rotates clockwise. The unlocking end 703 of the lock head lever 7 moves the strip protrusion 1202 of the square tongue lever 12. The square tongue lever 12 rotates counterclockwise. The extension of the square tongue lever 12 pushes the main lock tongue 6 to retract into the lock body, thus achieving manual unlocking.

[0055] Combined with appendix Figure 4 The main bolt 6, lock cylinder lever 7, and unlocking lever 11 are stacked. The unlocking lever 11 is hinged to the main bolt pin 21. The main bolt 6 has a straight waist hole 601, and the lock cylinder lever 7 has an arc waist hole 704. The main bolt pin 21 passes through the straight waist hole 601 and the arc waist hole 704. Both the lock cylinder lever 7 and the unlocking lever 11 are smaller in area than the main bolt 6, and both are located in front of the main bolt 6, with their edges not exceeding the movable area of ​​the main bolt 6. This avoids unnecessary space waste and greatly saves space inside the lock body, reducing the lock body volume. The lower right end of the lock cylinder lever 7 is hinged to the bottom shell 1 by a torsion spring and a rivet, and the upper right end has an arc-shaped notch to allow space for the rotation of the protrusion 1202. While reducing the overall size of the lock body and making it more compact, the internal transmission structure does not interfere with each other.

[0056] The locking block 14 has a second protrusion 1402, which is combined with the attached Figure 3The second protrusion 1402 is fitted with an unlocking piece 18, which is hinged and has two ends with a lever structure. The hinge point of the unlocking piece 18 is the same as the hinge point of the locking block 14, and a torsion spring is provided at the hinge point to provide a continuous reset force. The second protrusion 1402 is limited in the middle section of the unlocking piece 18 and drives the unlocking piece 18 to rotate. One end of the unlocking piece 18 overlaps with the baffle of the flip plate 19, and the other end of the unlocking piece 18 overlaps with the second lock head protrusion 702 of the lock head lever 7.

[0057] Combined with appendix Figure 5 , 6 The inner sides of the cam gear 13 and the square tongue block 12 are respectively provided with inner ring protrusion 1201 and inner ring protrusion 1302 for abutting cooperation. After the cam gear 13 rotates, the inner ring protrusion 1201 and inner ring protrusion 1302 abut against each other, and the cam gear 13 drives the square tongue block 12 to rotate together. The extension of the square tongue block 12 can control the main locking tongue 6.

[0058] Combined with appendix Figure 2 , 3 The unlocking piece 18 has a bent section in the middle, which is connected to the second protrusion 1402 by a crank-slider structure. The bent section forms a horizontal surface that slides with the second protrusion 1402. During manual unlocking, when the lock head lever 7 is turned clockwise, the second lock head protrusion 702 turns the unlocking piece 18 counterclockwise, thereby pushing the second protrusion 1402 upward. The left end of the locking block 14 disengages from the fork slide groove 401, realizing the unlocking of the directional lock of the flip tongue 4.

[0059] Working principle:

[0060] The flip tongue 4 can flip automatically, making it relatively convenient to automatically switch the two installation directions of the lock body without removing the panel 3 or replacing the flip tongue 4.

[0061] Locking block 14 locks and unlocks flip tongue 4:

[0062] Method 1: When the trigger tongue 5 retracts, the reduction motor 8 drives the cam gear 13, and the cam gear 13 pushes the locking block 14 to lock and unlock the flip tongue 4.

[0063] Method 2: When the trigger tongue 5 extends, the locking block 14 is unlocked by the structural transmission of the trigger tongue 5 bracket; when the trigger tongue 5 retracts into the locking block 14, it is locked.

[0064] Locking and unlocking of main bolt 6:

[0065] Method 1: Electronic locking and unlocking, the motor drives the gear, the gear drives the square tongue block 12 to move the main lock tongue 6 to lock and unlock;

[0066] Method 2: Mechanical unlocking. The square steel lever can be used to move the square steel lever block to unlock the main lock tongue 6 through the transmission mechanism, avoiding the risk of not being able to open the door if the electronic components malfunction.

[0067] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
