[0028] like Figures 1 to 3As shown, an electromechanical integrated door handle locking mechanism includes a door handle 1, a key lock cylinder 3, a PCBA board 4, a motor 6, a latch 10, and a second spring 11. One end of the door handle 1 is rotatably mounted to the door handle housing 12, and the other end of the door handle 1 passes through the door handle housing 12 to form a hook arm 13. The motor 6 drives a sector gear 8 through a gear set 7. The key lock cylinder 3 is connected to the sector gear 8 through a first spring 9, and pressing the key lock cylinder 3 engages it with the sector gear 8. One end of the latch 10 is aligned with the first hook groove 14 of the hook arm 13, and the other end is connected to a protrusion 81 on the sector gear 8. The second spring 11 is installed in a groove on one side of the sector gear 8 and abuts against the other end of the latch 10, used for disengaging the sector gear 8. Simultaneously, the second spring 11 can also... The PCBA board 4 is electrically connected to the motor 6 to control the forward and reverse rotation and opening and closing of the motor 6. The key lock cylinder 3 is used to open or lock the door handle 1. When the key lock cylinder 3 is pressed down and turned, the key lock cylinder 3 engages with the sector gear 8, causing the sector gear 8 to rotate and drive the latch 10 to insert into the first hook groove 14 of the hook arm 13 to lock the door handle 1. The first spring 9 can separate the key lock cylinder 3 from the sector gear 8, thus playing a disengaging role. In addition, the PCBA board 4 can also control the motor 6 to rotate in the first direction. The motor 6 drives the gear set 7 to drive the sector gear 8 to rotate and drive the latch 10 to insert into the first hook groove 14 of the hook arm 13 to lock the door handle 1.
[0029] In one embodiment, the sector gear 8 includes a gear portion 82, a protrusion 81 on one side of the gear portion 82, and a first tooth portion 83 on the other side of the gear portion 82. The key lock cylinder 3 is installed in the receiving groove of the door handle housing 12 and has a second tooth portion 31 that engages with the first tooth portion 83. Pressing down the key lock cylinder 3 causes the second tooth portion 31 to engage with the first tooth portion 83. After the two engage, they become a whole. When the key lock cylinder 3 is rotated, the sector gear 8 will also rotate.
[0030] In one embodiment, the gear set 7 includes a worm gear 71, a first gear 72, a second gear 73, and a third gear 74. The worm gear 71 is connected to the output shaft of the motor 6 and meshes with the first gear 72. The second gear 73 meshes with both the first gear 72 and the third gear 74. The third gear 74 also meshes with the sector gear 8. The motor 6 drives the worm gear 71, thereby causing the first gear 72, the second gear 73, and the third gear 74 to rotate, which in turn drives the sector gear 8 to rotate.
[0031] In one embodiment, the PCBA board 4 is installed inside the door handle housing 12 on one side of the key lock cylinder 3.
[0032] Example 2
[0033] like Figure 1-4As shown, another aspect of this utility model also provides a lock, including the electromechanical integrated door handle locking mechanism in embodiment 1, and a latch assembly 2. The latch assembly 2 includes a connector 21, a secondary lock plate 22, and a main lock plate 23 rotatably mounted on the latch mounting plate 24. The first end of the connector 21 is located in the second hook groove 15 of the hook arm 13, and the second end of the connector 21 is engaged with the first end of the secondary lock plate 22. The second end of the secondary lock plate 22 abuts against the blocking block 25. The third end of the secondary lock plate 22 is engaged with the first end of the main lock plate 23 through a groove and a protrusion. A third spring 26 is connected between the fourth end of the secondary lock plate 22 and the second end of the main lock plate 23. Pulling the door handle 1 causes the hook arm 13 on it to drive the connector 21, which in turn drives the secondary lock plate 22, causing the secondary lock plate 22 to separate from the main lock plate 23, thereby unlocking. Conversely, when the door handle 1 is released, the secondary lock plate 22 and the main lock plate 23 are locked together under the action of the third spring 26.
[0034] In one embodiment, a position switch 5 is installed on the side of the door handle 1 near the latch assembly 2. The position switch 5 is used to detect whether the door handle 1 has returned to its original position.
[0035] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
