[0025] For the handle seat 1 mentioned above, please refer to Figure 2 , Figure 3 and Figure 5The handle base 1 has a first cavity 14 and a second cavity 15 that are connected to each other. The first cavity 14 extends along a first direction x, and the second cavity 15 extends along a third direction z. The second cavity 15 is used to accommodate the clutch assembly 3, and the first cavity 14 is used to accommodate the transmission assembly 4, the first drive assembly 5, and the second drive assembly 6. The handle base 1 includes a base 11, a cover plate 12, and a limiting plate 13. The cover plate 12 covers the base 11 to form the first cavity 14 and the second cavity 15. The base 11 has a screw hole 111 in the second cavity 15 for connecting with the clutch assembly 3, and a groove 112 in the first cavity 14 for accommodating a portion of the second drive assembly 6. A limiting plate 13 is located between the cover plate 12 and the base 11.

The limiting plate 13 is connected to the base 11, and its shape matches the shape of the aforementioned components. The limiting plate 13 serves to limit the clutch assembly 3, transmission assembly 4, first drive assembly 5, and second drive assembly 6, thereby enhancing structural stability. The first direction x and the third direction z are perpendicular to each other.

[0026] For the square rod 2 mentioned above, please refer to Figure 1 and Figure 5 The square rod 2 extends along the third direction z. One end of the square rod 2 is located in the second cavity 15 and is connected to the second rotating member 32. The other end of the square rod 2 extends out of the second cavity 15 and is used to connect with the door lock body, thereby realizing the connection between the handle device 1000 and the door lock body.

[0027] For the clutch assembly 3 mentioned above, please refer to Figure 4 and Figure 5 The clutch assembly 3 is located in the first cavity 14. The clutch assembly 3 includes a first rotating member 31, a second rotating member 32, and a clutch member 33. The first rotating member 31 is sleeved on the second rotating member 32 and is connected to the handle seat 1. The second rotating member 32 is used to connect to the door lock body. The first rotating member 31 is provided with a connecting through hole 311, which is used for a screw to pass through and be screwed into the screw hole 111 to fix the first rotating member 31 to the base 11. One end of the second rotating member 32 along the third direction z is located in the first rotating member 31, and the other end of the second rotating member 32 along the third direction z passes through the first rotating member 31 and is connected to the square rod 2.

[0028] The clutch component 33 includes a clutch lever 331 and a spring 332. The spring 332 is sleeved on the clutch lever 331 and abuts against the boss 3311 of the clutch lever 331. The clutch lever 331 and the spring 332 are located at one end of the first rotating component 31 along the first direction x. The clutch lever 331 can move between a first position and a second position along the first direction x.

[0029] When the clutch lever 331 is in the second position, it is not in contact with the second rotating member 32, and the spring 332 is in its initial state, holding the clutch lever 331 in the second position. At this time, the first rotating member 31 can rotate relative to the second rotating member 32, that is, the clutch assembly 3 is in the unlocked state, and the square rod 2 and the door lock body do not rotate with the rotation of the handle seat 1. When the clutch lever 331 is in the first position, one end of the clutch lever 331 along the first direction x is engaged with the second rotating member 32, and the other end of the clutch lever 331 along the first direction x is located on the first rotating member 31. The spring 332 is in the compressed state. At this time, the first rotating member 31 and the second rotating member 32 are connected through the clutch lever 331, and the second rotating member 32 can rotate with the first rotating member 31, that is, the clutch assembly 3 is in the locked state. When the handle seat 1 is rotated, the square rod 2 and the door lock body will rotate accordingly.

[0030] For the aforementioned transmission component 4, please refer to Figure 4 and Figure 5 The transmission assembly 4 includes a sliding block 41 and a limiting seat 42. The limiting seat 42 is sleeved on the sliding block 41. One end of the limiting seat 42 along the first direction x has a through hole, and both sides of the limiting seat 42 along the second direction y have limiting through holes 422. The outer walls of the sliding block 41 along both sides of the second direction y have protrusions 411 located within the limiting through holes 422. When one end of the sliding block 41 moves in and out of the sliding hole 421 along the first direction x, the protrusions 411 move along the limiting through holes 422, thereby limiting the movement of the sliding block 41 along the first direction x. A portion of the protrusions 411 extends out of the limiting seat 42 from the limiting through holes 422, and the portion of the protrusions 411 outside the limiting through holes 422 is used to connect with the second drive assembly 6.

[0031] For the first driving component 5 mentioned above, please refer to [link / reference]. Figure 4 and Figure 5 The first drive assembly 5 is located in the limiting seat 42. The first drive assembly 5 includes a motor 51 and a first elastic element 52. The rotating shaft 511 of the motor 51 extends along the first direction x. The rotating shaft 511 is provided with a first locking block 5111. The first elastic element 52 is sleeved around the rotating shaft 511 and contacts the first locking block 5111. The first elastic element 52 is connected to the sliding block 41. When the rotating shaft 511 of the motor 51 rotates, the first elastic element 52 moves along the rotating shaft 511 along the first direction x, thereby driving the sliding block 41 to move along the first direction x, thus realizing that the motor 51 drives the transmission assembly 4 to move along the first direction x.

[0032] For the second drive component 6, please refer to Figure 4 and Figure 5The second drive assembly 6 includes a handle lock cylinder 61, a connecting rod 62, and a second elastic member 63. One end of the connecting rod 62 along the first direction x is connected to the protrusion 411 of the sliding block 41, and the other end of the connecting rod 62 along the first direction x abuts against the handle lock cylinder 61. The second elastic member 63 is disposed in the groove 112 of the base 11, and one end of the second elastic member 63 abuts against the handle lock cylinder 61. The handle lock cylinder 61 is used to drive the connecting rod 62 to move along the first direction x after the key is inserted, thereby pushing the sliding block 41 to move along the first direction x, thus realizing that the handle lock cylinder 61 drives the transmission assembly 4 to move along the first direction x. The second elastic member 63 is used to reset the handle lock cylinder 61 and the connecting rod 62 after the key is disengaged from the handle lock cylinder 61.

[0033] Furthermore, the handle lock cylinder 61 includes a lock cylinder seat 611, a lock cylinder body 612, and a push rod 613. The lock cylinder seat 611 is connected to the base 11. The lock cylinder body 612 is disposed on the lock cylinder seat 611. A rotating through hole 6121 is provided on the side wall of the lock cylinder body 612. The rotating through hole 6121 extends and bends along the first direction x. The push rod 613 is sleeved on one end of the lock cylinder body 612, and a lock hole 6122 is provided on the other end of the lock cylinder body 612. The lock hole 6122 is used for key insertion to drive the push rod 613 to move. One end of the push rod 613 along the first direction x abuts against the connecting rod 62. The other end of the push rod 613 is connected to the lock cylinder body 612. A second locking block 6131 is provided on the other end of the push rod 613, and the second locking block 6131 is located in the rotating through hole 6121.

[0034] When the key is inserted into the lock cylinder 6122 and turned, the lock cylinder body 612 rotates accordingly. Since the rotating through-hole 6121 extends and bends along the first direction x, the movement of the second locking block 6131 within the rotating through-hole 6121 pushes the push rod 613 to move along the first direction x. The movement of the push rod 613 then pushes against the connecting rod 62, causing the connecting rod 62 and its connected sliding block 41 to move along the first direction x. This movement is transmitted to the clutch assembly 3 via the transmission assembly 4. Specifically, the movement of the sliding block 41 drives the clutch rod 331 to move between a first position and a second position, thereby enabling the clutch assembly 3 to switch between the locked and unlocked positions.

[0035] The linkage 62 includes a horizontal bar 621 and two vertical bars 622. The vertical bars 622 extend along a first direction x, and the horizontal bar 621 extends along a second direction y. The two vertical bars 622 are respectively connected to both ends of the horizontal bar 621 and are respectively connected to two protrusions 411. One side of the horizontal bar 621 abuts against the top rod 613 of the handle lock cylinder 61, and the other side of the horizontal bar 621 abuts against the second elastic element 63. The linkage 62 has a "U"-shaped structure, which enhances the stability of the structure and makes the force transmission during the transmission process more uniform and smooth. The first direction x, the second direction y, and the third direction z are all perpendicular to each other.

[0036] It should be noted that the handle lock cylinder 61, motor 51 and clutch assembly 3 are arranged in sequence along the first direction x. The motor 51 is located between the two vertical rods 622. The structure is compact, which improves the space utilization rate inside the handle seat 1 and is conducive to the miniaturization of the handle device 1000.

[0037] In some embodiments, the handle device 1000 further includes a control module disposed inside the handle base 1, preferably within the first cavity 14. The control module is electrically connected to the motor 51 of the first drive assembly 5. The control module is used to receive external control signals or internal sensor signals, and control the start, stop, and rotation direction of the motor 51 according to these signals. By controlling the operation of the motor 51, remote or intelligent control of the transmission assembly 4 and the clutch assembly 3 is achieved, thereby controlling the locking and unlocking states of the handle device 1000.

[0038] In this embodiment of the invention, the handle device 1000 independently drives the transmission component 4 via the first drive component 5 and the second drive component 6, thereby controlling the locking and unlocking of the clutch component 3. The first drive component 5 is electrically driven by a motor 51, and the second drive component 6 is mechanically driven by the handle lock cylinder 61, thus improving the security and reliability of the handle device 1000 when applied to a door lock. When power is sufficient, the user can quickly and conveniently open and lock the door lock using the motor 51 of the first drive component 5 via intelligent control or remote control. In emergency situations of insufficient or interrupted power, the user can still manually open and lock the door lock by operating the handle lock cylinder 61 with a key, which in turn mechanically drives the transmission component 4 via the second drive component 6, thereby controlling the clutch component 3.

[0039] This utility model also provides a door lock embodiment, which includes a door lock body and the above-mentioned handle device 1000. The structure and function of the handle device 1000 can be referred to the above embodiment, and will not be repeated here.

[0040] This utility model embodiment also provides an embodiment of opening and closing a door, which includes the door lock described above. The structure and function of the door lock can be referred to the above embodiment, and will not be repeated here.
