A new type of electronic lock body Technical Field
[0001] This invention belongs to the field of electronic locks and relates to a novel electronic lock body. Background Technology
[0002] Traditional electronic locks incorporate a clutch mechanism between the square core, square shaft, and toggle plate. However, this clutch mechanism is complex, has many parts, requires high precision, and has high production costs. Summary of the Invention
[0003] To address the aforementioned problems, this invention provides a novel electronic lock body. This device has the advantages of simple structure and unlocking by direct motor-driven reversing block to achieve internal and external reversing control.
[0004] The objective of this invention is achieved as follows:
[0005] A novel electronic lock body includes a lock shell, a latch inside the lock shell, a latch hole formed at the front end of the lock shell for the latch to extend out, and a linkage end at the rear end of the latch. Two actuating plates are also rotatably arranged inside the lock shell, namely an inner actuating plate and an outer actuating plate. An inner core hole is formed in the middle of the inner actuating plate, and an outer core hole is formed in the middle of the outer actuating plate. The inner actuating plate extends toward the linkage end to form an inner actuating end, and the outer actuating plate extends toward the linkage end to form an outer actuating end.
[0006] A motor bracket is rotatably mounted inside the lock housing, and a motor is fixed inside the motor bracket. A reversing block is connected to the output end of the motor. An inner unlocking end extends from the inner toggle plate toward the motor, and an outer unlocking end extends from the outer toggle plate toward the motor. The inner and outer unlocking ends are respectively located on both sides of the motor. In normal operation, the reversing block is located in front of the inner unlocking end and is linked with the inner unlocking end. When unlocking, the motor controls the reversing block to rotate to the front of the outer unlocking end and is linked with the outer unlocking end.
[0007] The lock housing is also provided with a square tongue, and the lock housing has a square tongue hole corresponding to the square tongue. A slanted groove is formed on the square tongue. A slider is formed on the motor bracket. The slider is slidably disposed in the slanted groove. When the inner unlocking end or the outer unlocking end pushes the reversing block to rotate the motor bracket, the slider slides in the slanted groove to retract the square tongue into the lock housing. An inner deadbolt end is formed behind the inner unlocking end of the motor bracket, and an outer deadbolt end is formed behind the outer unlocking end of the motor bracket. When the inner unlocking end pushes the inner deadbolt end to rotate the motor bracket in the opposite direction, the slider slides in the slanted groove in the opposite direction to push the square tongue out of the lock housing.
[0008] With the above settings, electronic unlocking methods such as fingerprint unlocking or facial recognition unlocking are used to control the motor to drive the reversing block to rotate, achieving inward and outward reversing control. This allows for the functionality of an electronic lock without a complex clutch structure. In normal operation, the reversing block is located on the front side of the inner unlocking end. Moving the inner handle causes the inner handle's spindle to rotate the inner actuating plate clockwise. The inner unlocking end of the actuating plate moves the reversing block, which in turn rotates the motor bracket. The slider on the motor bracket slides within the inclined groove, retracting the latch into the lock housing. Simultaneously, the inner actuating end on the inner actuating plate retracts the latch into the lock housing, thus unlocking the lock. However, in normal operation, because the outer unlocking end is not linked to the reversing block, it cannot retract the latch. During unlocking, the motor controls the reversing block to rotate to the front of the outer unlocking end. The outer handle is then activated, causing the spindle of the outer handle to rotate the outer actuating plate clockwise. The outer unlocking end of the actuating plate moves the reversing block, which in turn rotates the motor bracket. The slider on the motor bracket slides within the inclined groove, retracting the latch into the lock housing. Simultaneously, the outer actuating end on the outer actuating plate retracts the latch into the lock housing, thus unlocking the lock. After unlocking, a set time (usually 2-5 seconds) is set, and the motor controls the reversing block to rotate back to the front of the inner unlocking end.
[0009] When the inner handle is rotated in the opposite direction, the inner unlocking end pushes the inner deadbolt end, causing the motor bracket to rotate in the opposite direction. The slider then slides in the opposite direction within the inclined groove, pushing the square latch out of the lock housing, thus achieving deadbolt locking. Alternatively, when the outer handle is rotated in the opposite direction, the outer unlocking end pushes the outer deadbolt end, causing the motor bracket to rotate in the opposite direction. The slider then slides in the opposite direction within the inclined groove, pushing the square latch out of the lock housing, thus achieving deadbolt locking.
[0010] The invention is further configured such that: a battery box is provided inside the lock housing, and a power source is provided inside the battery box, which is electrically connected to the motor.
[0011] The present invention is further configured such that: the battery box extends a limiting guide end toward the commutator block, the limiting guide end is disposed in front of the commutator block and spaced apart from the commutator block; in normal state, the commutator block is disposed in front of the inner unlocking end and can slide along the inner side of the limiting guide end; when unlocking, the commutator block rotates to the front of the outer unlocking end and can slide along the outer side of the limiting guide end.
[0012] With the above settings, the limit guide end can ensure the stable movement of the reversing block during the unlocking process, thereby achieving stable unlocking.
[0013] The present invention is further configured such that: the motor bracket includes a base plate and a top cover, a motor mounting cavity is formed between the base plate and the top cover, and the motor is fixed in the motor mounting cavity.
[0014] The present invention is further configured such that: a rotating shaft is fixed on the motor bracket, and a rotating hole is formed in the lock housing, with the rotating shaft and the rotating hole rotatably engaged.
[0015] The invention is further configured such that: the lock housing corresponding to the motor bracket is also formed with an arc-shaped limiting groove, and the motor bracket extends a limiting slide post toward the arc-shaped limiting groove.
[0016] By setting the arc-shaped limiting groove, the motor bracket can be controlled to rotate according to the set shape, making the structure more stable.
[0017] The invention is further configured such that: a tongue guide groove is formed inside the lock housing, a tongue post is provided at the rear end of the tongue, the tongue post passes through the tongue guide groove, a spring is sleeved on the tongue post, one end of the spring abuts against the rear end of the tongue, and the other end of the spring abuts against the front end of the tongue guide groove.
[0018] The above settings enable the latch to automatically retract and extend out of the lock housing, and also reset the inner and outer toggle plates, making it easier to unlock next time.
[0019] The present invention is further configured such that: the linkage end is fixedly connected to the tongue post, the inner actuating end is located in front of the linkage end, the outer actuating end is located in front of the linkage end, and the inner actuating end and the outer actuating end are respectively located on both sides of the tongue post.
[0020] The above settings allow the inner and outer toggle plates to be spaced apart, reducing mutual interference.
[0021] The present invention is further configured such that: the linkage end is formed with a guide protrusion, and the lock housing is formed with a guide groove corresponding to the guide protrusion, and the guide protrusion is slidably disposed in the guide groove.
[0022] The above settings can make the movement of the tongue more stable.
[0023] The present invention is further configured such that: a deadbolt cylinder is provided inside the lock housing, the deadbolt cylinder is located behind the square tongue, and a deadbolt groove is formed at the rear end of the square tongue corresponding to the deadbolt cylinder.
[0024] By using a deadbolt lock cylinder, the lock can be opened with a key even when there is no power.
[0025] The outstanding and beneficial technical effects of this invention compared to the prior art are: by using electronic unlocking methods such as fingerprint unlocking or facial recognition unlocking, the motor is controlled to drive the reversing block to rotate, thereby realizing internal and external reversing control, thus achieving the function of an electronic lock without a complex clutch structure, and the structure is simple and reduces costs.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0039] A novel electronic lock body includes a lock shell 1, a latch 2 inside the lock shell 1, a latch hole formed at the front end of the lock shell 1 for the latch 2 to extend out, and a linkage end 3 at the rear end of the latch 2. Two actuating plates are also rotatably arranged inside the lock shell 1, namely an inner actuating plate 41 and an outer actuating plate 51. An inner core hole 42 is formed in the middle of the inner actuating plate 41, and an outer core hole 52 is formed in the middle of the outer actuating plate 51. The inner actuating plate 41 extends toward the linkage end 3 to form an inner actuating end 43, and the outer actuating plate 52 extends toward the linkage end 3 to form an outer actuating end 53.
[0040] A motor bracket 6 is rotatably mounted inside the lock housing 1, and a motor 7 is fixed inside the motor bracket 6. A reversing block 8 is connected to the output end of the motor. An inner toggle plate 41 extends toward the motor 7 to form an inner unlocking end 44, and an outer toggle plate 51 extends toward the motor to form an outer unlocking end 54. The inner unlocking end 44 and the outer unlocking end 54 are respectively located on both sides of the motor 7. In normal state, the reversing block 8 is located in front of the inner unlocking end 44 and is linked with the inner unlocking end 44. When unlocking, the motor 7 controls the reversing block 8 to rotate to the front of the outer unlocking end 54 and is linked with the outer unlocking end 54.
[0041] The lock housing is also provided with a square tongue 9, and the lock housing has a square tongue hole formed corresponding to the square tongue. A slanted groove 10 is formed on the square tongue. A slider 11 is formed on the motor bracket 6. The slider 11 is slidably disposed in the slanted groove 10. When the inner unlocking end 44 or the outer unlocking end 54 pushes the reversing block 8 to rotate the motor bracket 6, the slider 11 slides in the slanted groove 10 to retract the square tongue 9 into the lock housing 1. An inner deadbolt end 45 is formed behind the inner unlocking end 44 of the motor bracket 6, and an outer deadbolt end 55 is formed behind the outer unlocking end 54 of the motor bracket 6. When the inner unlocking end 44 pushes the inner deadbolt end 45 to rotate the motor bracket 6 in the opposite direction, the slider 11 slides in the opposite direction in the slanted groove 10 to push the square tongue 9 out of the lock housing 1.
[0042] With the above settings, the motor 7 drives the reversing block 8 to rotate through electronic unlocking methods such as fingerprint unlocking or facial recognition unlocking, thereby realizing internal and external reversing control. This achieves the function of an electronic lock without a complex clutch structure.
[0043] The lock housing also contains a battery box 12, which contains a power source that is electrically connected to the motor 7.
[0044] The battery box 12 extends a limiting guide end 13 toward the commutator block 8. The limiting guide end 13 is located in front of the commutator block 8 and spaced apart from it. In normal operation, the commutator block 8 is located in front of the inner unlocking end 44 and can slide along the inner side of the limiting guide end 13. During unlocking, the commutator block 8 rotates the front side 54 of the outer unlocking end and can slide along the outer side of the limiting guide end 13. Through the above configuration, the limiting guide end 13 ensures stable movement of the commutator block during unlocking, thereby achieving stable unlocking.
[0045] The motor bracket 6 includes a base plate 61 and a top cover 62, with a motor mounting cavity formed between the base plate 61 and the top cover 62, and the motor 7 is fixed in the motor mounting cavity.
[0046] A rotating shaft 14 is fixed on the motor bracket 6, and a rotating hole 15 is formed in the lock housing. The rotating shaft 14 and the rotating hole 15 are rotatably engaged.
[0047] The lock housing 1 also has an arc-shaped limiting groove formed corresponding to the motor bracket 6, and the motor bracket 6 extends a limiting slide post toward the arc-shaped limiting groove. By setting the arc-shaped limiting groove, the motor bracket 6 can be controlled to rotate according to the set shape, making the structure more stable.
[0048] The lock housing also has a tongue guide groove 18 formed inside. A tongue post 19 is provided at the rear end of the tongue 2, passing through the tongue guide groove 18. A spring 20 is fitted onto the tongue post 19, with one end of the spring 20 abutting the rear end of the tongue 2 and the other end abutting the front end of the tongue guide groove 18. This configuration allows the tongue 2 to automatically return to its original position and extend out of the lock housing 1 after retraction, thereby resetting the inner actuating plate 41 and the outer actuating plate 51 for easier unlocking next time.
[0049] The linkage end 3 is fixedly connected to the tongue post 19. The inner actuating end 43 is located in front of the linkage end 3, and the outer actuating end 53 is located in front of the linkage end 3. The inner actuating end 43 and the outer actuating end 53 are respectively located on both sides of the tongue post 19. Through the above arrangement, the inner actuating plate 43 and the outer actuating plate 53 can be spaced apart to reduce mutual interference.
[0050] The linkage end 3 is formed with a guide protrusion 21, and the lock housing 1 is formed with a guide groove 22 corresponding to the guide protrusion 21. The guide protrusion 21 is slidably disposed in the guide groove 22. Through the above arrangement, the movement of the latch bolt can be made more stable.
[0051] The lock housing 1 also includes a deadbolt cylinder 23, which is located behind the square latch 9. A deadbolt groove 24 is formed at the rear end of the square latch corresponding to the deadbolt cylinder 23. This deadbolt cylinder allows the lock to be opened with a key even in the event of a power outage.
[0052] Working principle of the invention:
[0053] This type of lock is commonly used on office doors. The inner and outer handles of this lock rotate independently. The inner handle rotates by inserting the inner core shaft into the inner core hole 42, which in turn rotates the inner actuating plate 41. The outer handle rotates by inserting the outer core shaft into the outer core hole 52, which in turn rotates the outer actuating plate 51.
[0054] In normal condition, the reversing block 8 is located in front of the inner unlocking end 44. When the inner handle is turned, the inner spindle of the inner handle drives the inner actuating plate 41 to rotate clockwise. The inner unlocking end 44 of the inner actuating plate 41 drives the reversing block 8 to move. The movement of the reversing block 8 drives the motor bracket 6 to rotate. The slider 11 on the motor bracket 6 slides in the inclined groove 10 to retract the square tongue 9 into the lock housing 1. At the same time, the inner actuating end 43 on the inner actuating plate 41 drives the inclined tongue 2 to retract into the lock housing, thereby unlocking. However, in normal condition, since the outer unlocking end 54 is not linked with the reversing block 8, the outer unlocking end 54 cannot drive the square tongue 9 to retract.
[0055] During unlocking, the motor 7 controls the reversing block 8 to rotate to the front of the outer unlocking end 54, and the outer handle is turned. The outer spindle of the outer handle drives the outer actuating plate 51 to rotate clockwise. The outer unlocking end 54 of the outer actuating plate 51 drives the reversing block 8 to move. The reversing block 8 drives the motor bracket 6 to rotate. The slider 11 on the motor bracket 6 slides in the inclined groove 10 to retract the square tongue 9 into the lock shell 1. At the same time, the outer actuating end 53 on the outer actuating plate 51 drives the inclined tongue 2 to retract into the lock shell 1, so that the lock can be unlocked.
[0056] After unlocking, a specified time (usually 2-5 seconds) is set, and motor 7 controls reversing block 8 to rotate back to the front of inner unlock end 44.
[0057] When the inner handle is rotated in the opposite direction, the inner unlocking end 44 pushes the inner deadbolt end 45, causing the motor bracket 6 to rotate in the opposite direction. Simultaneously, the slider 11 slides in the opposite direction within the inclined groove 10, pushing the square tongue 9 out of the lock housing, thus achieving deadbolt locking. Alternatively, when the outer handle is rotated in the opposite direction, the outer unlocking end 54 pushes the outer deadbolt end 55, causing the motor bracket 6 to rotate in the opposite direction. Simultaneously, the slider 11 slides in the opposite direction within the inclined groove 10, pushing the square tongue 9 out of the lock housing, thus achieving deadbolt locking.
[0058] This invention features a simple structure and achieves internal and external reversing control for unlocking through a motor-driven commutator block.
[0059] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
