[0024] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.
[0025] Please see Figure 1 The handle device 1000 includes a handle seat (not shown), a clutch assembly 1, a transmission assembly 2, and a square rod 3. Both the clutch assembly 1 and the transmission assembly 2 are disposed on the handle seat. One end of the square rod 3 is connected to the clutch assembly 1, and the other end of the square rod 3 is used to connect to the lock body. The clutch assembly 1 is used to lock and disengage the handle seat and the square rod 3, thereby achieving the locking and disengagement of the handle device 1000 and the lock body. The transmission assembly 2 is used to drive the clutch assembly 1 to move.
[0026] For the clutch assembly 1 mentioned above, please refer to Figures 2 to 4 The clutch assembly 1 includes a first rotating member 11, a second rotating member 12, a first elastic member 13, and a clutch member 14. The first rotating member 11 is sleeved on the second rotating member 12. The first rotating member 11 is connected to the handle seat and is provided with a guide groove 110. The clutch member 14 is disposed in the guide groove 110 and can move along the guide groove 110 between a first position and a second position. Along the moving direction of the clutch member 14, the two ends of the guide groove 110 are provided with movable through holes 1101 for the two ends of the clutch member 14 to pass through. The second rotating member 12 is provided with a groove 120 and a square hole 121. The square hole 121 is used for inserting one end of the square rod 3. The first elastic member 13 is used to align and connect the groove 120 and the guide groove 110.
[0027] When the clutch 14 is in the first position, one end of the clutch 14 extends into the groove 120 through the movable through hole 1101, and the other end of the clutch 14 is located in the guide groove 110. At this time, the second rotating member 12 can rotate with the first rotating member 11, that is, the clutch assembly 1 is in the locked state. When the handle seat is rotated, the lock body rotates with the handle seat via the square rod 3. When the clutch 14 is in the second position, the clutch 14 is located in the guide groove 110 and the clutch 14 does not extend into the groove 120. At this time, the first rotating member 11 can rotate relative to the second rotating member 12, that is, the clutch assembly 1 is in the unlocked state. When the handle seat is rotated, the square rod 3 and the lock body do not rotate with the handle seat.
[0028] In some embodiments, please refer to Figure 2 The first rotating member 11 is provided with a cavity 111 and a first connecting through hole 112, which communicates with the cavity 111. One end of the second rotating member 12 is located in the cavity 111, and the other end of the second rotating member 12 passes through the first connecting through hole 112 and is located outside the cavity 111. A limiting step 122 is formed between one end and the other end of the second rotating member 12. The limiting step 122 abuts against the periphery of the first connecting through hole 112 facing the cavity 111, thereby restricting the axial movement of the second rotating member 12 and ensuring that the second rotating member 12 is stably sleeved inside the first rotating member 11.
[0029] For the first elastic element 13 mentioned above, please refer to Figure 2 and Figure 4In some embodiments, a first elastic member 13 is sleeved on one end of a second rotating member 12, and the two ends of the first elastic member 13 clamp the first rotating member 11 and the second rotating member 12, aligning the groove 120 and the guide groove 110. Specifically, along the circumference of the first rotating member 11, the first rotating member 11 is provided with a first through hole 113 and a second through hole 114, both of which communicate with the cavity 111. A first protrusion 115 is provided between the first through hole 113 and the second through hole 114. Along the circumference of the second rotating member 12, the second rotating member 12 is provided with a second protrusion 123, and along the radial direction of the first rotating member 11, the projection of the second protrusion 123 overlaps with the first protrusion 115. The second elastic member 15 is a torsion spring, the center of which is sleeved on one end of the second rotating member 12, and the two ends of the torsion spring clamp the first protrusion 115 and the second protrusion 123, aligning the groove 120 and the guide groove 110.
[0030] When no external force is applied to the handle assembly 1000, the first elastic member 13 remains in a naturally clamped state, and the groove 120 and the guide groove 110 are aligned and connected, allowing the clutch member 14 to smoothly slide along the guide groove 110 to enter or exit the groove 120. When the clutch assembly 1 is in the unlocked state, when the handle seat is rotated, the first rotating member 11 rotates relative to the second rotating member 12. At this time, the groove 120 and the guide groove 110 are no longer completely aligned. After the handle seat is released, under the elastic restoring force of the first elastic member 13, the first rotating member 11 gradually returns to the position aligned with the second rotating member 12. The first elastic member 13 ensures the relative stability of the positions of the first rotating member 11 and the second rotating member 12.
[0031] It is understood that the structure of the first elastic member 13 is not limited to the above-described limitations and can also be other structures. For example, in some other embodiments, the first rotating member 11 is provided with a first limiting through hole along its circumference, the first elastic member 13 is connected to the second rotating member 12, and the two ends of the first elastic member 13 respectively abut against the two end walls of the first limiting through hole along its circumference. The first elastic member 13 can be configured as a torsion spring, with the center of the torsion spring sleeved on one end of the second rotating member 12, and the two ends of the torsion spring respectively abutting against the two end walls of the first limiting through hole along its circumference. The first limiting through hole can also be as follows: Figure 2 The first through hole 113 or the second through hole 114 shown.
[0032] In some embodiments, please refer to Figure 2 and Figure 4The clutch assembly 1 further includes a second elastic element 15, which is disposed in the guide groove 110 and connected to the clutch member 14. The outer diameter of the second elastic element 15 is larger than the diameter of the movable through hole 1101. When the clutch member 14 is not subjected to driving force, the second elastic element 15 keeps the clutch member 14 in a second position; when the clutch member 14 is in the first position, after the driving force is removed, the second elastic element 15 resets the clutch member 14 to the second position. Specifically, the clutch member 14 is provided with a boss 141, the outer diameter of which is larger than the diameter of the movable through hole 1101. The second elastic element 15 is sleeved on the clutch member 14, one end of which abuts against the boss 141, and the other end of which abuts against the periphery of the movable through hole 1101. When the transmission assembly 2 drives the clutch 14 to move from the second position to the first position, the second elastic element 15 is compressed between the boss 141 and the movable through hole 1101; when the transmission assembly 2 separates from the clutch 14, under the action of the elastic restoring force of the second elastic element 15, the clutch 14 resets from the first position to the second position.
[0033] For the aforementioned transmission component 2, please refer to Figures 4 to 6 The transmission assembly 2 includes a limiting seat 21, a motor 22, a third elastic element 23, and a sliding block 24. The limiting seat 21 is connected to the handle seat and has a first cavity 210 and a second cavity 211. The limiting seat 21 includes a partition 213 located between the first cavity 210 and the second cavity 211. The partition 213 has a shaft through hole 2130 communicating with the first cavity 210 and the second cavity 211. One end of the limiting seat 21 has a sliding hole 214 communicating with the first cavity 210. The opposite side walls of the limiting seat 21 each have a second limiting through hole 215 communicating with the first cavity 210. The motor 22 is located in the second cavity 211, and the motor 22's rotating shaft 221 passes through the shaft through hole 2130 and is located in the first cavity 210. The third elastic element 23 and the sliding block 24 are located in the first cavity 210. The third elastic element 23 is sleeved on the rotating shaft 221 of the motor 22. The rotating shaft 221 of the motor 22 is provided with a locking block 2211. The locking block 2211 is in contact with the third elastic element 23. The third elastic element 23 is configured as a spring.
[0034] Please see Figure 5The sliding block 24 includes a top plate 241 and a side plate 242, which are vertically connected. The top plate 241 is used to contact and connect with the clutch 14, and can enter and exit the first cavity 210 through the sliding hole 214 of the limiting seat 21. A second connecting through hole 2420 is provided on the side of the side plate 242 parallel to the axial direction of the rotating shaft 221. The two ends of the third elastic member 23 respectively abut against the two end walls of the second connecting through hole 2420 along the axial direction of the rotating shaft 221, thereby connecting the third elastic member 23 to the sliding block 24. A third protrusion 2421 is provided on the two ends of the side plate 242 perpendicular to the axial direction of the rotating shaft 221, and the third protrusion 2421 can move within the second limiting through hole 215. The length of the second limiting through hole 215 along the axial direction of the rotating shaft 221 is equal to the distance between the first position and the second position. The axial movement of the sliding block 24 is limited by the limiting seat 21, thereby limiting the axial movement of the clutch 14, so that the clutch 14 will not move excessively, and improving the reliability of the handle device 1000.
[0035] In some embodiments, the sliding block 24 further includes a base plate 243, through which the shaft 221 of the motor 22 passes, and a third elastic member 23 is located between the base plate 243 and the top plate 241.
[0036] In some embodiments, please refer to Figure 6 The side wall of the limiting seat 21 is also provided with a third limiting through hole 216, which is used for the two ends of the third elastic member 23 to pass through. Along the axial direction of the rotating shaft 221, the length of the third limiting through hole 216 is greater than the length of the second limiting through hole 215, and the difference between the length of the third limiting through hole 216 and the length of the second limiting through hole 215 is equal to the distance between the first position and the second position. The third limiting through hole 216 further enhances the axial limiting of the sliding block 24.
[0037] It is understood that the structure of the limiting seat 21 and the sliding block 24 is not limited to the above-mentioned limitations, and can also be other structures. For example, the sliding block 24 may include one or more third protrusions 2421. The third protrusions 2421 can be disposed on the side wall of the sliding block 24 perpendicular to the axial direction, or on the side wall of the sliding block 24 parallel to the axial direction. Correspondingly, the position of the second limiting through hole 215 of the limiting seat 21 is matched and disposed.
[0038] When the motor 22 rotates, the third elastic element 23 can move axially along the shaft 221, and drive the sliding block 24 to move, thereby driving the clutch 14 to move along the guide groove 110 between the first position and the second position. Specifically, when the shaft 221 of the motor 22 rotates in one of the clockwise and counterclockwise directions, the third elastic element 23 moves along the locking block 2211 away from the motor 22, and drives the sliding block 24 to move away from the motor 22. The top plate 241 disengages from the sliding hole 214, and the top plate 241 pushes the clutch 14 to move from the second position to the first position. The second elastic element 15 is elastically compressed until the clutch 14 moves to the first position, realizing the locking function of the clutch assembly 1. When the shaft 221 of the motor 22 rotates in the other direction between clockwise and counterclockwise, the third elastic element 23 moves along the locking block 2211 toward the direction closer to the motor 22, causing the sliding block 24 to move toward the direction closer to the motor 22. The top plate 241 gradually moves toward the first cavity 210, and the clutch 14 returns to the second position under the elastic force of the second elastic element 15, and the clutch assembly 1 returns to the unlocked state.
[0039] In this embodiment of the utility model, a handle device 1000 is provided, in which the clutch component 1 is disposed in the handle seat. It has the characteristics of compact structure and reliable transmission, which is conducive to the miniaturization of door locks.
[0040] This utility model provides a door lock embodiment, which includes a lock body and the aforementioned handle device 1000. The device and function of the handle device 1000 can be referred to the above embodiment, and will not be repeated here.
[0041] In this embodiment of the utility model, by placing the clutch assembly 1 in the handle device 1000, the installation thickness of the door lock is effectively reduced, and the ease of installation of the door lock is improved.
[0042] It should be noted that while the preferred embodiments of this utility model are provided in the specification and accompanying drawings, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.
