[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0026] like Figures 1 to 6 As shown, the intelligent door lock for lightweight hall door hanging plate of the utility model includes a sliding frame 1, a driving member 2, a locking member 3, a locking plate 4 and a hall door 5. The sliding frame 1 can be driven by a belt or a chain, so that the hanging wheel 6 moves on the track, and the hall door 5 is driven to open or close by the sliding frame 1.
[0027] A hanging pulley 6 is provided in the middle of the sliding frame 1 , and the hanging pulley 6 is arranged on a track, so that the weight of the hall door 5 is carried by the hanging pulley 6 .
[0028] The driving member 2 is connected to the sliding frame 1 . The driving member 2 is provided with symmetrically arranged hinge arms 7 , and a hinge area 8 is formed between the hinge arms 7 .
[0029] The locking member 3 is disposed within the hinge region 8, with one end hinged to the hinge arm 7 via a hinge rod 9. The locking member 3 comprises a hinge portion 10, a rod 11, and a locking body 12. The rod 11 connects the hinge portion 10 and the locking body 12, and the rod 11 and the locking body 12 are arranged perpendicularly. The hinge portion 10 is hinged to the hinge arm 7 via the hinge rod 9, forming a movable gap 13 between the hinge portion 10 and the hinge arm 7, allowing the locking member 3 to move left and right within the hinge region 8, facilitating movement of the locking body 12 within the first guide slot 14, the second guide slot 15, the third guide slot 16, and the fourth guide slot 17.
[0030] The locking plate 4 cooperates with the locking member 3 . The locking plate 4 is provided with a locking groove and a guide groove 19 . The locking member 3 enters the locking groove under the guidance of the guide groove 19 .
[0031] The locking groove is composed of a first guide groove 14, a second guide groove 15, a third guide groove 16 and a fourth guide groove 17. One end of the first guide groove 14 is connected to one end of the second guide groove 15, the other end of the second guide groove 15 is connected to one end of the third guide groove 16, the other end of the third guide groove 16 is connected to one end of the fourth guide groove 17, and the other end of the fourth guide groove 17 is connected to one end of the first guide groove 14. The guide groove 19 is arranged at the connection between the first guide groove 14 and the fourth guide groove 17.
[0032] First guide groove 14 consists of a first guide section 20 and a second guide section 21. The first guide section 20 is lower than the second guide section 21 and is the same height as guide groove 19. The second guide section 21 is higher than the second guide groove 15 and the third guide groove 16. This allows locking body 12 to enter first guide groove 14 from guide groove 19 and then, due to the height difference, enter second guide groove 15. Once in second guide groove 15, locking body 12 cannot return to first guide groove 14.
[0033] The first guide section 20 and the second guide section 21 are connected via a first transition section 22 .
[0034] The fourth guide groove 17 is composed of a third guide segment 23 and a fourth guide segment 24. The height of the third guide segment 23 is consistent with that of the second guide groove 15 and the third guide groove 16, while the height of the fourth guide segment 24 is higher than that of the third guide segment 23. The height of the fourth guide segment 24 is also higher than that of the guide groove 19. This allows the locking body 12 to enter the fourth guide groove 17 from the third guide groove 16 and then into the guide groove 19, maintaining reciprocating motion without being able to move back.
[0035] The third guide section 23 and the fourth guide section 24 are connected via a second transition section 25. A blocking opening 26 is formed at the connection between the third guide groove 16 and the fourth guide groove 17.
[0036] The movement sequence of the locking body 12 is that the guide groove 19 enters the first guide groove 14, enters the second guide groove 15 from the first guide groove 14, enters the third guide groove 16 from the second guide groove 15, enters the fourth guide groove 17 from the third guide groove 16, and finally enters the guide groove 19 again from the fourth guide groove 17.
[0037] A protrusion 27 and a recessed opening 28 are provided at the connection between the second guide groove 15 and the third guide groove 16. The center horizontal lines of the protrusion 27 and the recessed opening 28 do not overlap, so that the protrusion 27 is set toward the second guide groove 15 and the recessed opening 28 is set toward the third guide groove 16, so that the locking body 12 that reaches the second guide groove 15 enters the recessed opening 28 through the guidance of the protrusion 27, and the locking body 12 that comes out of the recessed opening 28 will enter the blocking opening 26 through the guidance of the third guide groove 16.
[0038] An unlocking port 29 is provided on the locking plate 4, a plate body 30 is provided on the locking member 3, and an unlocking member 31 is provided at the lower end of the unlocking port 29. The unlocking member 31 is set on the hall door 5. After the unlocking member 31 rotates, it pushes the plate body 30 upward to keep the locking member 3 out of the restriction of the locking groove.
[0039] The unlocking member 31 is composed of a rotating portion 32 and a pushing portion 33 . The rotating portion 32 is provided with a square hole 34 . The hall door 5 is also provided with a similar square hole 34 .
[0040] When the elevator breaks down, a key with a cross-section that matches the square hole 34 can be inserted into the square hole 34, and the unlocking member 31 can be rotated so that the unlocking member 31 pushes the plate 30 at the upper end of the unlocking port 29, so that the locking body 12 is lifted up from the locking groove, and the hall door 5 can be pried open.
[0041] When the hall door 5 is closed normally, the sliding frame 1 is kept driving the driving member 2, and the driving member 2 pushes the locking member 3 to move in the guide groove 19. After the hall door 5 is closed, the locking body 12 enters the first guide groove 14 along the guide groove 19 and then enters the recessed opening 28 to lock. After the hall door 5 is closed, a small gap is left between the hall doors 5, which is convenient for opening the hall doors 5 in case of elevator failure. It also makes it easier for the sliding frame 1 to push the driving member 2 to continue to bring the two hall doors 5 closer together. Then, the locking body 12 is guided by the third guide groove 16 to the fourth guide groove 17 and then enters the guide groove 19, thereby unlocking the hall door 5 and ensuring that the hall door 5 can be opened normally.
[0042] When the elevator is in normal operation, the hall door 5 is first driven to close. When the door needs to be opened, the hall door 5 is first kept moving a short distance in the closing direction so that the locking body 12 is guided into the fourth guide groove 17 through the third guide groove 16, and then the hall door 5 is opened in the reverse direction.
[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
