DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-6 , an intelligent elevator access control safety control device, comprising a housing 1, the housing 1 is provided with a protrusion 11, the protrusion 11 is detachably connected to the elevator car through a quick release part 2, the end surface of the housing 1 is provided with an operation panel 3 and a card swiping area 4, and the end surface is slidably connected with a protective cover 5;

[0024] A driving assembly 6 is provided in the housing 1 , and the driving assembly 6 is used to drive the protective cover 5 to slide. A control unit is provided in the housing 1 .

[0025] Furthermore, the quick-release part 2 includes a base 21, which is fixed to the elevator car through fasteners and has a plug-in portion 22 fixedly connected to its end face. A cavity 23 is provided in the raised portion 11, and the plug-in portion 22 is L-shaped and slidably connected to the cavity 23.

[0026] It should be supplemented that the fastener includes a locking bolt, and the end face of the base 21 is provided with a mounting hole at the corner, and the mounting hole is threadedly connected to the elevator car through the locking bolt, wherein the housing 1 and the plug-in part 22 are quickly disassembled and assembled to facilitate maintenance and replacement of the access control.

[0027] Furthermore, the side of the cavity 23 is slidably connected to a plug rod 25 through a mounting groove 24, one end of the plug rod 25 is provided with an arc surface 251, and a spring 26 is fixedly connected between the other end and the mounting groove 24, and the end face of the plug-in portion 22 is provided with a socket 221 matching the plug rod 25.

[0028] In more detail, an electric push rod 27 is fixedly installed on the side of the cavity 23, and a slide plate 28 is slidably connected to both sides of its inner wall. The slide plate 28 is fixedly connected to the axial end of the electric push rod 27, and a guide slope 281 is provided on its side. The guide slope 281 slides against the arc surface 251.

[0029] It is worth mentioning that the electric push rod 27 and the card swiping area 4 are electrically connected to the control unit. The resident swipes the card to read the card in the card swiping area 4 to send an electrical signal to the control unit, and then the control unit sends an electrical signal to the electric push rod 27 to drive the slide plate 28 to move, thereby preventing the housing 1 from being disassembled by the outside.

[0030] The insertion rod 25 engages with the insertion hole 221 to achieve the purpose of fastening the housing 1 and the plug-in portion 22. When the slide plate 28 moves, the guide slope 281 contacts the arc surface 251 to contact and squeeze the insertion rod 25 so that the insertion rod 25 retracts.

[0031] It should be noted that a guiding slope is provided above the insertion rod 25. Specifically, after the insertion rod 25 is retracted to a suitable position, the plug-in portion 22 slides against the guiding slope, and then the shell 1 is pushed to separate the shell 1 from the plug-in portion 22.

[0032] In general, the driving assembly 6 includes a screw rod 61 and a guide rod 62. The screw rod 61 is rotatably connected to the shell 1 and is fixedly connected to the guide rod 62. Both ends of the protective cover 5 extend to form guide parts 51. A pair of guide parts 51 are respectively threadedly connected to the screw rod 61 and slidably connected to the guide rod 62.

[0033] Finally, a driving motor 63 is fixedly installed in the housing 1 , a worm 64 is fixedly connected to the shaft end of the driving motor 63 , a worm wheel 65 is fixedly installed at the bottom end of the lead screw 61 , and the worm 64 rotates in meshing engagement with the worm wheel 65 .

[0034] It is worth mentioning that the advantage of the transmission through the worm wheel 65 and the worm 64 is that the self-locking property of the worm wheel and the worm 64 is to prevent the protective cover 5 from sliding due to external force.

[0035] Specifically, the driving motor 63 is electrically connected to the control unit, and the driving motor 63 drives the worm 64 to drive the worm wheel 65 to rotate, and then the worm wheel 65 drives the screw rod 61 to rotate, so as to drive the protective cover 5 to rise and fall;

[0036] Wherein, a avoidance groove corresponding to the card swiping area 4 is provided at the bottom of the protective cover 5 .

[0037] Working mode: When working, the resident swipes the card in the card swiping area 4 to read the card, and then the control unit sends an electric signal to the electric push rod 27 to drive the slide plate 28 to move. While the slide plate 28 moves, the guide inclined surface 281 contacts the arc surface 251, and the insertion rod 25 is pressed to retract the insertion rod 25, and then the shell 1 is pushed to separate the shell 1 from the plug-in portion 22;

[0038] Then, the card reading method generates an electrical signal to drive the motor 63, which drives the worm 64 to drive the worm wheel 65 to rotate, and the worm wheel 65 drives the screw rod 61 to rotate. The protective cover 5 is driven by the screw rod 61 to rise and fall in coordination with the guide rod 62.

[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
