Description

Technical Field

[0001] This invention relates to a fully automatic lock body, and more particularly to a mechanism for separating the motor from the mechanical structure of a fully automatic lock body. Background Technology

[0002] Currently, fully automatic lock bodies are becoming increasingly popular. The fully automatic lock body can control the rotation of the motor through the motor circuit board 35 program, which in turn drives the related accessories to open and close the lock body; the fully automatic lock body can also be mechanically unlocked by inserting a key into the lock cylinder.

[0003] When the motor of the fully automatic lock body is powered off or in an accident, it may suddenly jam. Because the motor is jammed, the transmission mechanism inside the fully automatic lock body cannot move. At this time, the key cannot be used to mechanically unlock the lock, causing the fully automatic lock body to fail to unlock, which causes trouble for users. Summary of the Invention

[0004] To overcome the above-mentioned defects, the present invention provides a fully automatic lock body motor separation mechanism, which can separate the motor from the transmission mechanism when mechanically unlocking with a key, ensuring that mechanical unlocking can still be performed with a key even when the motor is jammed.

[0005] The technical solution adopted by this invention to solve its technical problem is: a fully automatic lock body motor separation mechanism, including a lock head dial, a motor, a gear set, and a main lock tongue assembly. The motor's power output shaft can rotate in both directions. The rotation of the gear set and the lock head dial can drive the main lock tongue on the main lock tongue assembly to extend and retract, thereby unlocking or locking. It also includes a clutch, a clutch transmission assembly, and a push plate. The clutch is movably installed in the fully automatic lock body and can be circumferentially stopped by the power input end of the motor's power output shaft and the gear set. The push plate is movably installed in the fully automatic lock body. The movement of the push plate can push the clutch to move, thereby disengaging it from the power input end of the gear set or the motor's power output shaft. The rotation of the lock head dial also drives the push plate to move synchronously through the clutch transmission assembly.

[0006] As a further improvement of the present invention, the clutch is circumferentially stopped and axially slidable by a set distance on the outside of the motor power output shaft. An eccentric protrusion is provided on the axial end face of the clutch facing away from the motor, and an eccentric groove is provided on the power input end of the gear set. The eccentric protrusion on the clutch is inserted into or separated from the eccentric groove on the power input end of the gear set as the clutch slides back and forth along the axial direction of the motor power output shaft.

[0007] As a further improvement of the present invention, a clutch limiting plate is also provided. The clutch limiting plate is fixedly installed in the fully automatic lock body. A motor mounting plate and a gear mounting plate are fixedly installed parallel to each other along the axial direction of the motor power output shaft on the clutch limiting plate. A first through hole is formed on the motor mounting plate, and a second through hole is provided on the gear mounting plate. The motor is fixedly installed on the motor mounting plate, and the motor power output shaft extends through the first through hole into the space between the motor mounting plate and the gear mounting plate. The clutch component is sleeved on the outside of the motor power output shaft, and both axial ends of the clutch component are respectively stopped between the motor mounting plate and the gear mounting plate. The power input end of the gear set is axially stopped. The clutch is rotatable in the circumferential direction and inserted into the second through hole. The eccentric protrusion on the clutch can be inserted into or withdrawn from the eccentric groove on the power input end of the gear set as the clutch moves between the motor mounting plate and the gear mounting plate. The clutch has a radial concave ring or a radial convex ring on its side wall. The push plate can slide a set distance along the axial direction of the motor power output shaft and is mounted on the clutch limiting plate. The push plate has a moving protrusion or a moving groove. The moving protrusion or moving groove on the push plate can be inserted with the radial concave ring or radial convex ring on the side wall of the clutch to achieve axial moving and synchronous movement.

[0008] As a further improvement of the present invention, the structure of the gear set, which is axially stopped and circumferentially rotatable and inserted into the second through hole, is as follows: the gear set includes a main gear and a transmission gear knob. The transmission gear knob is rotatably mounted on the inner wall of the fully automatic lock body. The transmission gear knob is provided with a transmission gear and an eccentric actuating part that can slide the main lock tongue assembly to realize unlocking and locking. The drive gear is rotatably mounted in the fully automatic lock body. The drive gear meshes with the transmission gear of the transmission gear knob. The eccentric groove is provided on the end face of one axial end of the drive gear. One end of the drive gear is inserted into the second through hole. An annular limiting groove is formed on the outer circumferential wall of the drive gear. A retaining spring is rotatably sleeved in the annular limiting groove. The retaining spring is fixedly connected to the gear mounting plate.

[0009] As a further improvement of the present invention, the push plate is provided with at least two elongated holes extending axially along the motor power output shaft, and at least two connecting screws are threadedly connected to the clutch limiting plate. The connecting screws are slidably inserted into the elongated holes of the push plate, and the heads of the connecting screws are stopped on the surface of the push plate opposite to the clutch limiting plate. The clutch limiting plate is also provided with a reset slot extending axially along the motor power output shaft. A reset baffle is provided on the side wall of the push plate. The reset baffle is slidably inserted into the reset slot. A push plate reset spring is also provided in the reset slot. The two ends of the push plate reset spring in the elastic extension direction are respectively pressed against the side wall of the reset slot and the reset baffle on the push plate, thereby giving the push plate a state in which the eccentric protrusion on the clutch is inserted into the eccentric groove of the power input end of the gear set.

[0010] As a further improvement of the present invention, the clutch transmission assembly includes a transmission baffle and a connecting member for blocking the extension and retraction of the latch of the fully automatic lock body. The transmission baffle is installed in the automatic lock body and can slide linearly a set distance to block and disengage the latch of the fully automatic lock body from retracting inward. The connecting member is rotatably installed in the fully automatic lock body. The side wall of the connecting member is hinged to the transmission baffle and can slide relative to it along the sliding direction perpendicular to the transmission baffle. The connecting member rotates as the transmission baffle slides linearly. The rotation of the connecting member can actuate the push plate to move linearly. The rotation of the lock head dial can drive the transmission baffle to slide linearly.

[0011] As a further improvement of the present invention, the connector forms a lever structure with the pivot connected to the fully automatic lock body as the fulcrum, with a hinge shaft formed on one end and a lever formed on the other end. The transmission baffle is provided with a long slot extending perpendicular to its sliding direction. The hinge shaft on one end of the connector can be slidably inserted into the long slot. The push plate is provided with a toggle protrusion. The lever at the other end of the connector can push the outer surface of the toggle protrusion to make the push plate slide.

[0012] As a further improvement of the present invention, a transmission baffle reset elastic element is also provided. The transmission baffle reset elastic element provides the transmission baffle with an elastic reset force along its sliding direction, so that the transmission baffle maintains the state of blocking the tongue retraction and the connecting member is in the state of stopping the connection between the motor power output shaft and the gear set power input end in the circumferential direction.

[0013] As a further improvement of the present invention, the transmission baffle reset elastic element is a torsion spring installed in the fully automatic lock body. The transmission baffle is formed by bending to form a limiting wall perpendicular to its sliding direction. The two elastic legs of the torsion spring are respectively pressed against the inner wall of the fully automatic lock body and the surface of the limiting wall of the transmission baffle.

[0014] As a further improvement of the present invention, an unlocking baffle, an unlocking baffle reset elastic element, and an opening / closing baffle positioning post are also provided. The unlocking baffle is installed on the main lock tongue assembly and can slide linearly a set distance along the direction of extension and retraction of the main lock tongue. The unlocking baffle and the main lock tongue assembly are respectively provided with elongated clearance holes extending along the direction of extension and retraction of the main lock tongue. The side wall of the elongated clearance hole of the unlocking baffle along the sliding direction of the unlocking baffle is also provided with a positioning opening groove. The opening / closing baffle positioning post is fixedly installed in the fully automatic lock body. The opening / closing baffle positioning post can be slidably inserted into the elongated clearance hole of the main locking assembly. The opening / closing baffle positioning post can be relatively stopped and inserted into the positioning opening groove or can be slidably inserted into the elongated clearance hole of the unlocking baffle as the unlocking baffle slides. The unlocking baffle reset elastic element provides the unlocking baffle with an elastic holding force to keep the positioning opening groove and the opening / closing baffle positioning post in a stopped insertion state.

[0015] The beneficial effects of this invention are as follows: By designing a clutch component, this invention enables the separation or transmission connection between the motor power output shaft and the gear set used for power transmission. Furthermore, by incorporating a clutch transmission assembly and a push plate within the fully automatic lock body, when the key is used for unlocking, the lock head dial, through the clutch transmission assembly, drives the push plate to push the clutch component to the position separating the motor and the gear set. This achieves automatic separation of the motor and gear set. Even if the motor is jammed, it will not interfere with the rotation of the gear set, thus satisfying the key unlocking requirement. This avoids the problem of fully automatic locks being unable to be mechanically unlocked by key due to motor malfunction and jamming. Moreover, it eliminates the need for manual or other operations to separate the motor and gear set; the motor and gear set achieve automatic separation simultaneously with key unlocking, improving the ease of use of the fully automatic lock.

[0025] Example: A fully automatic lock body motor-mechanical separation mechanism includes a lock head dial 1, a motor 2, a gear set, and a main lock tongue assembly 3. The motor's power output shaft 6 can rotate in both directions. The rotation of the gear set and the lock head dial 1 can drive the main lock tongue on the main lock tongue assembly 3 to extend and retract, thereby unlocking or locking. The mechanism is characterized by further including a clutch 4, a clutch transmission assembly, and a push plate 5. The clutch 4 is movably mounted within the fully automatic lock body and can be circumferentially stopped by the power input end of the motor's power output shaft 6 and the gear set. The push plate 5 is movably mounted within the fully automatic lock body. The movement of the push plate 5 can push the clutch 4 to disengage from the power input end of the gear set or the motor's power output shaft 6. The rotation of the lock head dial 1 also drives the push plate 5 to move synchronously through the clutch transmission assembly.

[0026] When mechanical unlocking is performed using a key, the key drives the lock head dial 1 to rotate. As the lock head dial 1 rotates, it drives the push plate 5 to move through the clutch transmission assembly. The push plate 5 pushes the clutch 4 to move, causing the motor 2 and the gear set to be separated. Continuing to turn the key causes the main lock tongue assembly 3 to retract into the fully automatic lock head, thereby unlocking. During the key unlocking process, since the motor 2 and the gear set are separated, the gear set is in an idle state. Even if the power output shaft of the motor 2 is jammed, it will not affect the key's mechanical unlocking.

[0027] The clutch 4, which is circumferentially stopped and axially slidable by a set distance, is sleeved on the outside of the motor power output shaft 6. An eccentric protrusion 7 is provided on the axial end face of the clutch 4 facing away from the motor 2, and an eccentric groove 8 is provided on the power input end of the gear set. The eccentric protrusion 7 on the clutch 4 engages or disengages with the eccentric groove 8 on the power input end of the gear set as the clutch 4 reciprocates axially along the motor power output shaft 6. While sliding on the motor power output shaft 6, the clutch 4 maintains a circumferentially stopped connection with the motor power output shaft 6. The two can achieve the above function by using a non-circular cross-section fit. The axial sliding of the clutch 4 allows the eccentric protrusion 7 on its axial end face to insert into or exit the eccentric groove 8 on the power input end of the gear set, thereby achieving engagement or disengagement between the clutch 4 and the gear set. In addition, the clutch 4 can also move in other directions. After the clutch 4 moves to the designated position, it can simultaneously engage with the motor power output shaft 6 and the gear set power input end. When it leaves the designated position, it disengages from one or both of the motor power output shaft 6 and the gear set power input end. This is an equivalent replacement structure that can be easily conceived by those skilled in the art based on this application, and it also falls within the protection scope of this application.

[0028] A clutch limiting plate 9 is also provided, which is fixedly installed in the fully automatic lock body. A motor mounting plate 10 and a gear mounting plate 11 are fixedly installed on the clutch limiting plate 9 at parallel intervals along the axial direction of the motor power output shaft 6. A first through hole 12 is formed on the motor mounting plate 10, and a second through hole 13 is formed on the gear mounting plate 11. The motor 2 is fixedly installed on the motor 2 fixing plate. The motor power output shaft 6 extends through the first through hole 12 between the motor mounting plate 10 and the gear mounting plate 11. The clutch 4 is sleeved on the outside of the motor power output shaft 6, and the two ends of the clutch 4 are respectively stopped between the motor mounting plate 10 and the gear mounting plate 11. The power input end of the gear set is axially stopped and circumferentially stopped. The clutch 4 is rotatably inserted into the second through hole 13. The eccentric protrusion 7 on the clutch 4 can be inserted into or withdrawn from the eccentric groove 8 on the power input end of the gear set as the clutch 4 moves between the motor mounting plate 10 and the gear mounting plate 11. The clutch 4 has a radial concave ring 14 or a radial convex ring on its side wall. The push plate 5 can slide a set distance along the axial direction of the motor power output shaft 6 and is installed on the clutch limiting plate 9. The push plate 5 has a toggle protrusion 15 or a toggle groove. The toggle protrusion 15 or the toggle groove on the push plate 5 can be inserted with the radial concave ring 14 or the radial convex ring on the side wall of the clutch 4 to achieve axial toggle and move synchronously. The clutch 4 can only slide between the motor mounting plate 10 and the gear mounting plate 11 of the clutch limiting plate 9, which limits the sliding distance of the clutch 4 and prevents it from disengaging from the power output shaft of the motor 2. The push plate 5 is inserted into the radial concave ring 14 or radial convex ring on the side wall of the clutch 4 by actuating the protrusion 15 or actuating the groove, so that the clutch 4 slides linearly synchronously with the push plate 5. The push plate 5 can also adopt a swing structure, which is connected to the clutch 4 by a hinge structure.

[0029] The structure of the gear set, which is axially stopped and circumferentially rotatable and inserted into the second through hole 13, is as follows: The gear set includes a main gear 16 and a transmission gear knob 17. The transmission gear knob 17 is rotatably mounted on the inner wall of the fully automatic lock body. The transmission gear knob 17 is provided with a transmission gear and an eccentric actuating part that can slide the main lock tongue assembly 3 to realize unlocking and locking. The drive gear is rotatably mounted in the fully automatic lock body and meshes with the transmission gear of the transmission gear knob 17. The eccentric groove 8 is provided on the end face of one axial end of the drive gear. One end of the drive gear is inserted into the second through hole 13. An annular limiting groove 18 is formed on the outer circumferential wall of the drive gear. A retaining spring 19 is rotatably sleeved in the annular limiting groove 18. The retaining spring 19 is fixedly connected to the gear mounting plate 11. The drive gear is rotatable in the circumferential direction and axially stopped by the snap ring 19. The structure is simple and easy to install. The second through hole 13 of the gear mounting plate 11 can be a countersunk hole to accommodate and position the snap ring 19. In addition, the main gear 16 can also be connected to the gear mounting plate 11 axially stopped and rotatable in the circumferential direction by means of bushing and step surface cooperation. This is an equivalent replacement structure that can be easily thought of by those skilled in the art based on this application, and it also falls within the protection scope of this application.

[0030] The push plate 5 is provided with at least two elongated holes 20 extending axially along the motor power output shaft 6. The clutch limiting plate 9 is threaded with at least two connecting screws 21. The connecting screws 21 are slidably inserted into the elongated holes 20 of the push plate 5, and the heads of the connecting screws 21 stop on the surface of the push plate 5 facing away from the clutch limiting plate 9. The clutch limiting plate 9 is also provided with a reset slot 22 extending axially along the motor power output shaft 6. The push plate 5 is provided with a reset baffle 23 on its side wall. The reset baffle 23 is slidably inserted into the reset slot 22. The reset slot 22 is also provided with a push plate reset spring 24. The two ends of the push plate reset spring 24 in the elastic extension direction respectively press against the side wall of the reset slot 22 and the reset baffle 23 on the push plate 5, thereby giving the push plate 5 a state in which the eccentric protrusion 7 on the clutch 4 is inserted into the eccentric groove 8 of the power input end of the gear set. The push plate 5 is connected and positioned by sliding a set distance with the clutch limit plate 9 through the elongated hole 20 and the connecting screw 21. The push plate 5 is also automatically reset by the push plate reset spring 24, so that the clutch 4 automatically engages with the main gear 16 after the key unlocking is completed, ensuring that the next electric unlocking is successful.

[0031] The clutch transmission assembly includes a transmission baffle 25 and a connector 26 for blocking the extension and retraction of the latch of the automatic lock body. The transmission baffle 25 is installed in the automatic lock body and can slide linearly a set distance to block and disengage the latch of the automatic lock body from retracting inward. The connector 26 is rotatably installed in the automatic lock body. The side wall of the connector 26 is hinged to the transmission baffle 25 and can slide relative to it in the direction perpendicular to the sliding direction of the transmission baffle 25. The connector 26 rotates as the transmission baffle 25 slides linearly. The rotation of the connector 26 can actuate the push plate 5 to move linearly. The rotation of the lock head dial 1 can drive the transmission baffle 25 to slide linearly.

[0032] When unlocking, the transmission baffle 25 used to unlock the inclined lock becomes part of the clutch transmission assembly. After extending a certain distance in the opposite direction, it transmits power to the connecting piece 26. When unlocking, the transmission baffle 25 slides a certain distance in a straight line, which simultaneously drives the connecting piece 26 to rotate a certain angle. Then, the connecting piece 26 pushes the push plate 5 to slide in a straight line. This structure is simple, makes full use of the existing structure in the fully automatic lock body, and saves more internal space in the fully automatic lock body.

[0033] The connector 26 forms a lever structure with its pivot point connected to the automatic lock body as the fulcrum. One end has a hinge shaft 27, and the other end has a lever. The transmission baffle 25 has an elongated slot 28 extending perpendicular to its sliding direction. The hinge shaft 27 at one end of the connector 26 can slidably insert into the elongated slot 28. The push plate 5 has a lever-like protrusion 29. The lever at the other end of the connector 26 can push the outer circumferential surface of the lever-like protrusion 29 to slide the push plate 5. Using this lever structure, the clutch 4 can be moved with relatively small force, avoiding significant resistance to turning the key.

[0034] A reset elastic element is also provided for the transmission baffle 25. This reset elastic element provides the transmission baffle 25 with an elastic reset force along its sliding direction, so that the transmission baffle 25 remains in a state of blocking the retraction of the inclined tongue and keeps the connecting member 26 in a state of circumferential stop connection between the motor power output shaft 6 and the gear set power input end by the clutch 4. The reset elastic element of the transmission baffle 25 can realize the automatic reset of the transmission baffle 25 after unlocking, so that the inclined tongue is automatically locked, and will not interfere with the automatic restoration of the engagement state of the clutch 4.

[0035] The reset elastic element of the transmission baffle 25 is a torsion spring 30 installed in the automatic lock body. The transmission baffle 25 has a limiting wall 31 perpendicular to its sliding direction formed by bending. The two elastic legs of the torsion spring 30 are respectively pressed against the inner wall of the automatic lock body and the surface of the limiting wall 31 of the transmission baffle 25.

[0036] The system also includes an unlocking baffle 32, an unlocking baffle reset elastic element 33, and an opening / closing baffle positioning post 34. The unlocking baffle 32 is mounted on the main bolt assembly 3 and can slide linearly a set distance along the direction perpendicular to the extension and retraction of the main bolt. Both the unlocking baffle 32 and the main bolt assembly 3 have elongated clearance holes extending along the extension and retraction direction of the main bolt. The elongated clearance holes of the unlocking baffle 32 also have positioning opening slots on the side walls along the sliding direction of the unlocking baffle 32. The opening / closing baffle positioning post... 34 is fixedly installed in the fully automatic lock body. The opening and closing baffle positioning post 34 can be slidably inserted into the long strip clearance hole of the main locking assembly. The opening and closing baffle positioning post 34 can be relatively stopped inserted into the positioning opening groove or slidably inserted into the long strip clearance hole of the unlocking baffle 32 as the unlocking baffle 32 slides. The unlocking baffle reset elastic member 33 provides the unlocking baffle 32 with an elastic holding force to keep the positioning opening groove on it and the opening and closing baffle positioning post 34 in a stopped insertion state. When the key is used to open the door, the lock cylinder dial 1 will drive the unlocking baffle 32 upward. At this time, the unlocking baffle 32 will disengage from the closing baffle positioning post 34, so that the lock cylinder dial 1 can move the main bolt assembly 3 back and forth. When the door lock is in the locked state, under the action of the unlocking baffle reset elastic element 33, the unlocking baffle 32 will automatically reset to the state of being locked with the opening and closing baffle positioning post 34. At this time, the main bolt assembly 3 cannot slide to unlock and remains in the locked state.
