Description

Technical Field

[0001] This invention belongs to the field of locks. Background Technology

[0002] The unlocking process of a smart lock is automated, and at the same time, it creates a certain outward pushing effect. When locking, the user's pushing force during the locking process drives the linkage structure inside the lock body to automatically lock. However, if the user needs to apply a large amount of force throughout the entire locking process, it may affect the user's locking experience and easily cause locking failure. This solution provides a new smart lock body structure that not only achieves the above functions but also improves the user experience during the locking phase. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, the present invention provides an intelligent lock and its working method. The unlocking process is completed automatically, and at the same time, a certain outward pushing effect is formed during unlocking. When locking, the user's pushing force during the locking process drives the linkage structure inside the lock body to automatically lock.

[0004] Technical solution: To achieve the above objectives, the present invention provides an intelligent lock, comprising a lock base, a lock plate, a lock hook plate, a lock tongue plate, and a spring; the lock plate is fixedly connected to the lock base in parallel, and a U-shaped lock opening is provided on one side edge of the integral structure formed by the lock plate and the lock base.

[0005] The lock base and lock plate are integrally structured with hinge shafts a and b fixed vertically. Along the length of the latch plate, the hook plate has a protruding hook a, a protruding hook b, and a protruding hook c integrally formed. The latch plate has a protruding tongue integrally formed on the side near the hook plate. The portion of the hook plate between protruding hooks a and b is rotatably mounted on hinge shaft a. One end of the latch plate is rotatably mounted on hinge shaft b. The other end of the latch plate, tail a, is connected to the end of the hook plate away from protruding hook a, tail b, by a spring elastic pull. The end of the protruding tongue is engaged between protruding hooks b and c, and the hook plate and latch plate interlock under the tension of the spring.

[0006] Furthermore, in the interlocking state, a gap is formed between the end of the hook b and the outer contour of the locking tongue.

[0007] Furthermore, it also includes a latch arm, the end of which is provided with a locking pin that can be radially engaged into a U-shaped lock slot.

[0008] When the end of the tongue is engaged between hooks b and c, hooks b and a are located at the inner and outer ends of the U-shaped lock opening in the depth direction, and the locking pin engaged in the U-shaped lock opening is sandwiched between hooks b and a.

[0009] Furthermore, when the end of the tongue is stuck between the b-hook and the c-hook, and the locking tongue is forced to rotate clockwise around the b-hook hinge axis, the end of the tongue will push the c-hook, which in turn will push the locking hook plate to rotate counterclockwise around the a-hook hinge axis, so that the end of the tongue gradually passes over the c-hook and reaches the side of the c-hook away from the b-hook.

[0010] Furthermore, a drive post is vertically fixed to the tail of the locking tongue plate, and the drive post is pushed under the action of external force.

[0011] Furthermore, it also includes a linear slide bar, which is movably mounted on a linear guide rail on the lock seat along its length. The linear slide bar is parallel to the spring axis in its initial state. A push block is vertically fixed at one end of the linear slide bar, and the push block is located on the side of the drive post near the tail of b. The linear slide bar can drive the push block to push the drive post away from the tail of b, causing the lock tongue to rotate clockwise around the hinge axis of b. A linear array transmission tooth body is provided on one side of the linear slide bar along its length. A drive motor and a gear transmission structure are installed on the lock seat. The output end of the drive motor is driven by the gear transmission structure to cooperate with the linear array transmission tooth body on the linear slide bar, thereby driving the drive motor to drive the linear slide bar to slide along its own length.

[0012] Furthermore, a rotating shaft perpendicular to the locking tongue is provided on the side of the drive pile near the tail of b. The driver on the lock seat can drive the rotating shaft to rotate. A solenoid wheel is integrally provided on the rotating shaft. The outer contour of the solenoid wheel is a constant velocity spiral contour. The two ends of the constant velocity spiral contour are the proximal end and the distal end, respectively. The center of the vortex of the constant velocity spiral contour coincides with the rotating shaft. The drive pile, rotating shaft, and solenoid wheel are all metal conductive structures. In the initial state, when the end of the tongue is locked between the b and c protrusions, an electrically disconnected gap is formed between the proximal end of the constant velocity spiral contour and the drive pile. The solenoid wheel and rotating shaft are electrically grounded, and the drive pile is connected to the positive terminal of the power supply through a wire with a galvanometer and a protective resistor.

[0013] Furthermore, when locking, the locking pin is pushed into the U-shaped locking port along the depth direction. When the current detected by the galvanometer disappears, the driver is immediately controlled to drive the solenoid wheel to continue to rotate counterclockwise around the shaft, so that the constant velocity solenoid profile re-electrically contacts and continues to push the drive pin.

[0014] Beneficial effects: The present invention can complete the function of automatic unlocking, and at the same time, it forms a certain outward pushing effect. When locking, it uses the pushing force of the user during the locking process to drive the linkage structure in the lock body to automatically lock. At the same time, in the second embodiment, the overall resistance during the locking process is reduced, improving the user experience. Attached Figure Description

Detailed Implementation

[0016] The invention will now be further described with reference to the accompanying drawings.

[0017] As attached Figures 1 to 10 The smart lock shown includes a lock base 100, a lock plate 1, a lock hook 7, a lock tongue 8, and a spring 9; the lock plate 1 is fixedly connected to the lock base 100 in parallel, and a U-shaped lock opening 2 is provided on one side edge of the integral structure formed by the lock plate 1 and the lock base 100; it also includes a latch arm 5, and a latch post 6 perpendicular to the surface of the lock plate 1 is provided at the end of the latch arm 5, and the latch post 6 can be radially engaged into the U-shaped lock opening 2; in this case, the lock base 100 and the lock plate 1 are fixed to the cabinet body of the electric bicycle cabinet, and the latch arm 5 is fixedly connected to the cabinet door of the electric bicycle cabinet.

[0018] like Figure 4 , 56. A hinge shaft a 3 and a hinge shaft b 4 are vertically fixed on the integral structure formed by the lock base 100 and the lock plate 1. Along the length direction, the side of the lock hook piece 7 near the lock tongue piece 8 is integrally provided with a protruding hook a 20, a protruding hook b 19, and a protruding hook c 18. The side of the lock tongue piece 8 near the lock hook piece 7 is integrally provided with a protruding tongue 23. The portion of the lock hook piece 7 between the protruding hook a 20 and the protruding hook b 19 is rotatably mounted on hinge shaft a 3. One end of the lock tongue piece 8 is rotatably mounted on hinge shaft b 4. The other end of the lock tongue piece 8, tail a 12, is away from the lock hook piece 7 and away from the protruding hook a 19. One end b, tail 17 of hook 20 is elastically connected by spring 9; under the elastic pull of spring 9, the locking hook piece 7 always tends to swing clockwise around the axis of hinge shaft 3, and the locking tongue piece 8 always tends to swing counterclockwise around hinge shaft 4; under the elastic pull of spring 9, the end of the protruding tongue 23 is stuck between the protruding hook 19 and the protruding hook 18, so that the locking hook piece 7 and the locking tongue piece 8 are interlocked under the tension of spring 9; in the interlocked state, a gap 110 is formed between the end of the protruding hook 19 and the outer contour of the locking tongue piece 8 to prevent travel interference.

[0019] like Figure 5 When the end of the tongue 23 is engaged between the hook 19 (b) and the hook 18 (c), the hook 19 (b) and the hook 20 (a) are located at the inner and outer ends of the U-shaped lock opening 2 in the depth direction, respectively, and the locking pin 6, which is engaged in the U-shaped lock opening 2, is sandwiched between the hook 19 (b) and the hook 20 (a). When the end of the tongue 23 is engaged between the hook 19 (b) and the hook 18 (c), and the locking tongue plate 8 is forcibly rotated clockwise around the hinge axis 4 (b), the end of the tongue 23 will push the hook 18 (c), thereby pushing the locking hook plate 7 to rotate counterclockwise around the hinge axis 3 (a), causing the end of the tongue 23 to gradually pass over the hook 18 (c) and reach the side of the hook 18 away from the hook 19 (b). When the end of the tongue 23 passes over the hook 18 (c) and reaches the side of the hook 18 away from the hook 19 (b), the hook 20 (a) disengages outward from the outer end of the U-shaped lock opening 2, thus unlocking the lock. Figure 6 As shown.

[0020] The tail 12 of the locking tongue plate 8 is vertically fixed to the drive post 10, which is pushed by an external force.

[0021] First embodiment of the driving structure: It also includes a linear slide bar 13, which is movably mounted on a linear guide rail on the lock seat 100 along its length. The linear slide bar 13 is parallel to the axis of the spring 9 in its initial state. A push block 11 is vertically fixed at one end of the linear slide bar 13. The push block 11 is located on the side of the drive post 10 near the tail 17 of b. The linear slide bar 13 can drive the push block 11 to push the drive post 10 away from the tail 17 of b, causing the locking tongue 8 to rotate clockwise around the hinge axis 4 of b. A linear array transmission gear 14 is provided on one side of the linear slide bar 13 along its length. A drive motor 16 and a gear transmission structure 15 are mounted on the lock seat 100. The output end of the drive motor 16 is driven by the gear transmission structure 15 to engage with the linear array transmission gear 14 on the linear slide bar 13, thereby driving the linear slide bar 13 to slide along its own length.

[0022] The method of the first embodiment: In the initial state, the device is in a locked state. Under the elastic pull of the spring 9, the end of the tongue 23 is stuck between the hook 19 and the hook 18, so that the locking hook piece 7 and the locking tongue piece 8 are interlocked under the tension of the spring 9; the locking pin 6, which is inserted into the U-shaped lock mouth 2, is sandwiched between the hook 19 and the hook 20. In this state, since the hook 20 is located at the outer end of the depth direction of the U-shaped lock mouth 2, the locking pin 6 cannot be disengaged from the U-shaped lock mouth 2, thereby achieving the purpose of locking the electric bicycle cabinet door and entering the locked state. When the user issues an unlock command, automatic unlocking is required. The unlocking process is as follows: The drive motor 16 drives the linear slide bar 13 through the gear transmission structure 15, which in turn drives the push block 11 to push the drive post 10 away from the tail 17 of b. This forces the latch plate 8 to rotate clockwise around the hinge axis 4 of b. When the latch plate 8 is forced to rotate clockwise around the hinge axis 4 of b, the end of the convex tongue 23 will push the convex hook 18 of c, which in turn pushes the latch hook plate 7 around the hinge axis 3 of a. The counter-clockwise rotation causes the end of the tongue 23 to gradually pass over hook 18 (c) and reach the side of hook 18 away from hook 19 (b). When the end of the tongue 23 passes over hook 18 and reaches the side of hook 18 away from hook 19 (b), hook 20 (a) disengages outward from the outer end of the U-shaped lock 2, and the side of hook 19 (b) close to hook 20 (a) exerts a certain outward pushing force on the locking pin 6. The locking pin 6 disengages from the U-shaped lock 2, and the cabinet door opens, thus achieving unlocking and door opening. Figure 6 As shown, the drive motor 16 then drives the linear slide bar 13 back to the initial state through the gear transmission structure 15. Since the lock hook plate 7 and the lock tongue plate 8 enter a new interlocking state at this time, even if the linear slide bar 13 returns to the initial state, the lock body structure is still in the unlocked state.

[0023] After the user retrieves the item and closes the door, as the electric bicycle locker door is about to close completely, the locking pin 6 is pushed into the U-shaped lock opening 2 along the depth direction. During this process, the locking pin 6 forcibly presses the side of the protruding hook 19 (b) close to the protruding hook 20 (a) and pushes the protruding hook 19 inward, thereby forcing the locking hook piece 7 to rotate counterclockwise around the hinge axis 3 (a). At the same time, the protruding hook 18 (c) pushes the tongue 23, causing the locking tongue piece 8 to rotate clockwise around the hinge axis 4 (b). Finally, the end of the tongue 23 gradually passes over the protruding hook 18 (c), causing the end of the tongue 23 to re-lock between the protruding hook 19 (b) and the protruding hook 18 (c), restoring the initial locked state.

[0024] During the closing action described above, when the latch 6 is pushed into the U-shaped lock opening 2 along the depth direction, the latch 6 forcibly presses the side of the hook 19 (b) close to the hook 20 (a) inward, causing the locking hook piece 7 to rotate counterclockwise around the hinge axis 3 (a). During this process, the locking hook piece 7 is subjected to resistance not only from the spring 9 but also from the tongue 23. As a result, the user needs to use a large force to push the cabinet door to lock it while the latch 6 is pushed into the U-shaped lock opening 2 along the depth direction. Furthermore, the rebound force is relatively large and gradually increases throughout the process, affecting the user experience.

[0025] Second embodiment of the driving structure: A rotating shaft 25 perpendicular to the locking tongue 8 is provided on the side of the drive pile 10 near the tail 17 of b. The driver on the lock seat 100 can drive the rotating shaft 25 to rotate. A solenoid 27 is integrally provided on the rotating shaft 25. The outer contour of the solenoid 27 is a constant velocity spiral contour 26. The two ends of the constant velocity spiral contour 26 are the proximal end 26a and the distal end 26b, respectively. The center of the spiral of the constant velocity spiral contour 26 coincides with the rotating shaft 25. The drive pile 10, the rotating shaft 25 and the solenoid 27 are all metal conductive structures. In the initial state, when the end of the tongue 23 is stuck between the protrusion 19 of b and the protrusion 18 of c, an electrically disconnected gap 28 is formed between the proximal end 26a of the constant velocity spiral contour 26 and the drive pile 10. The solenoid 27 and the rotating shaft 25 are electrically grounded. The drive pile 10 is connected to the positive terminal of the power supply through a wire with a galvanometer 32 and a protective resistor.

[0026] The method of the second embodiment: In the initial state, the device is in a locked state. Under the elastic pull of the spring 9, the end of the tongue 23 is stuck between the hook 19 and the hook 18, so that the locking hook piece 7 and the locking tongue piece 8 are interlocked under the tension of the spring 9; the locking pin 6, which is inserted into the U-shaped lock mouth 2, is sandwiched between the hook 19 and the hook 20. In this state, since the hook 20 is located at the outer end of the depth direction of the U-shaped lock mouth 2, the locking pin 6 cannot be disengaged from the U-shaped lock mouth 2, thereby achieving the purpose of locking the electric bicycle cabinet door and entering the locked state; and in this state, an electrical disconnect gap 28 is formed between the proximal end 26a of the constant velocity spiral profile 26 and the drive post 10, and the galvanometer 32 cannot detect the current. When the user issues an unlock command, automatic unlocking is required. The unlocking process is as follows: The driver drives the solenoid wheel 27 to rotate counterclockwise around the shaft 25, causing the constant velocity spiral profile 26 to gradually make electrical contact and push the drive post 10, and the galvanometer 32 detects the current; the locking tongue 8 is forced to rotate clockwise around the hinge axis 4. When the locking tongue 8 is forced to deflect clockwise around the hinge axis 4, the end of the tongue 23 will push the hook 18, which in turn pushes the hook 7 to deflect counterclockwise around the hinge axis 3. The end of the tongue 23 gradually passes over the c-hook 18 and reaches the side of the c-hook 18 away from the b-hook 19; when the end of the tongue 23 passes over the c-hook 18 and reaches the side of the c-hook 18 away from the b-hook 19, the a-hook 20 disengages outward from the outer end of the U-shaped lock 2, and the side of the b-hook 19 close to the a-hook 20 exerts a certain outward pushing force on the locking pin 6, the locking pin 6 disengages from the U-shaped lock 2, the cabinet door opens, and the lock is unlocked. At this time, the rotation of the helical wheel 27 is immediately stopped. After the user retrieves the item and closes the door, as the electric bicycle locker door is about to close completely, the locking pin 6 is pushed into the U-shaped lock opening 2 along the depth direction. During this process, the locking pin 6 forcibly presses inward against the side of the protruding hook 19 closest to the protruding hook 20 (b), pushing the protruding hook 19 inward. This forces the locking hook piece 7 to rotate counterclockwise around the hinge axis 3 (a). Simultaneously, the protruding hook 18 (c) pushes the tongue 23, causing the locking tongue piece 8 to rotate clockwise around the hinge axis 4 (b). This clockwise rotation of the locking tongue piece 8 around the hinge axis 4 (b) is the initial stage of this rotation. The drive post 10 automatically and instantly disengages from the constant velocity spiral profile 26 of the helical wheel 27, causing the current detected by the galvanometer 32 to disappear immediately. When the current detected by the galvanometer 32 disappears, the driver immediately controls the helical wheel 27 to continue rotating counterclockwise around the shaft 25, causing the constant velocity spiral profile 26 to re-electrically contact and continue pushing the drive post 10, causing the latch plate 8 to actively rotate clockwise around the hinge axis 4, thus eliminating the need for the latch plate 7 to drive it. In the above process, except in the initial stage, the latch plate 7 only experiences resistance from the spring 9, without additional driving of the latch plate 8, thereby reducing the overall resistance during the closing process and improving the user experience. When the latch post 6 is fully pushed into the U-shaped lock opening 2 along the depth direction, as Figure 9As shown, the rotating shaft 25 continues to rotate counterclockwise, the drive pile 10 disengages from the distal end 26b of the constant velocity spiral profile 26, the drive pile 10 automatically loses the constraint of the constant velocity spiral profile 26, and the locking tongue 8 automatically returns to its original position under the tension of the spring 9, so that the end of the tongue 23 is once again locked between the b hook 19 and the c hook 18; returning to the initial locked state.

[0027] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
