Description

Technical Field

[0001] This utility model relates to the field of security device technology, and in particular to a multi-functional access control and detection device for elevator lobbies. Background Technology

[0002] Elevator lobby access control detection devices are intelligent security equipment primarily used to monitor and manage the opening and closing status of elevator lobby doors and personnel access permissions. They typically integrate door magnetic sensors, facial recognition, IC card readers, or QR code scanning modules to detect abnormal door openings in real time and notify property management personnel via audible and visual alarms or remote notification. Their core function is to prevent unauthorized entry, tailgating, and other security risks. They also work in conjunction with elevator control systems to achieve access control, improving elevator safety and management efficiency. They are suitable for residential buildings, office buildings, hospitals, and other similar locations.

[0003] Traditional elevator hall access control devices lack mechanical emergency exits. When power is out, the electronic access control system fails. If the hall door cannot be opened manually by mechanical means, passengers or rescuers will be blocked outside the elevator, delaying rescue opportunities and reducing rescue efficiency. At the same time, some non-professionals may attempt to force the door open. If the access control structure and the elevator hall door are not linked properly, the hall door may deform or open unexpectedly, causing a fall into the shaft and resulting in a serious safety accident.

[0004] Therefore, in response to the problem that traditional elevator hall access control detection devices lack mechanical emergency exits, which delays rescue opportunities, reduces rescue efficiency, and may even cause serious safety accidents, a multi-functional elevator hall access control detection device with mechanical emergency exits can be designed. Utility Model Content

Meanwhile, trapped individuals can manually open the mechanical lock to release the fixing to the moving door panel, pushing it to rotate the gears and drive the moving door panel to move linearly along the rack until the exit opens, enabling safe escape. The pressure sensor in this device is model CYYZ11.

[0008] Preferably, the drive assembly includes a variable frequency motor, a drive shaft, and a drive turntable. The variable frequency motor is fixedly connected to the mounting bracket, and the output end of the variable frequency motor is fixedly connected to the drive shaft. The variable frequency motor is used to drive the drive shaft to rotate. The drive turntable is fixedly connected to the drive shaft, and a belt is sleeved on the outside of the drive turntable.

[0009] Preferably, the transmission assembly includes a driven turntable, a rotating shaft, and a rotating chain. The other end of the belt is fitted with the driven turntable, and the rotating shaft is fixedly connected to the driven turntable. The rotating shaft is rotatably connected to the elevator car body, and the rotating chain is fitted on the outside of the rotating shaft. Two connecting components are fixedly connected to the rotating chain.

A rack 14 is connected to the side meshing connection and is fixedly connected to the elevator car body 1. When a user enters the elevator and passes through the access control detection, the drive component outputs power to the belt 4, causing the belt 4 to rotate and drive the transmission component to move. The transmission component drives the two connecting components to move linearly, realizing the opening and closing of the door 8. At the same time, the pressure sensor 9 is used for real-time detection. When the door 8 experiences abnormal impact or other dangerous situations, the drive component brakes in an emergency to avoid injury to personnel. Meanwhile, trapped personnel can manually open the mechanical lock 12 to release the fixation of the moving door panel 11, push the moving door panel 11, and cause the gear 13 to rotate, driving the moving door panel 11 to move linearly along the rack 14 until the exit opens, realizing safe escape. The pressure sensor 9 in this device is model CYYZ11.

[0024] Please see Figures 1-5In this embodiment, the drive assembly includes a variable frequency motor 301, a drive shaft 302, and a drive turntable 303. The variable frequency motor 301 is fixedly connected to the mounting bracket 2, and the output end of the variable frequency motor 301 is fixedly connected to the drive shaft 302. The variable frequency motor 301 drives the drive shaft 302 to rotate. The drive shaft 302 is fixedly connected to the drive turntable 303, and the belt 4 is sleeved on the outside of the drive turntable 303. The variable frequency motor 301 outputs power to the drive shaft 302, causing the drive shaft 302 to rotate, which in turn drives the drive turntable 303 to rotate, thereby realizing the rotation of the belt 4. The transmission assembly includes a driven turntable 501, a rotating shaft 502, and a rotating chain 503. The other end of the belt 4 is sleeved on the driven turntable 501, and the rotating shaft 502 is fixedly connected to the driven turntable 501. The rotating shaft 502 is rotatably connected to the elevator car. On body 1, a rotating chain 503 is sleeved on the outer side of the rotating shaft 502. Two connecting components are fixedly connected to the rotating chain 503. The belt 4 drives the driven turntable 501 to rotate, thereby causing the rotating shaft 502 to rotate with the driven turntable 501, realizing the rotation of the rotating chain 503. The connecting components include a door clamping knife 601, a door hanging plate 602, and pulleys 603. The door clamping knife 601 is fixedly connected to the rotating chain 503, and the door hanging plate 602 is fixedly connected to the door clamping knife 601. Several pulleys 603 are rotatably connected to the inner side of the door hanging plate 602. The door clamping knife 601 and the door hanging plate 602 are both fixedly connected to the door leaf 8. The rotating chain 503 drives the door clamping knife 601 to move linearly. By clamping the door clamping knife 601, the door hanging plate 602 and the door leaf 8 move together. The pulleys 603 are used for movement limitation and support.

[0025] Please see Figures 2-5 In this embodiment, a guide rail 7 is fixedly connected to the elevator car body 1. The guide rail 7 and a pulley 603 are slidably connected. By allowing the pulley 603 to slide on the guide rail 7, the door leaf 8 moves along the guide rail 7, ensuring a smooth and safe movement. Several door shoes 10 are fixedly connected to the bottom of the door leaf 8. A door sill 101 is provided at the bottom of the elevator car body 1. The door shoes 10 and the door sill 101 are slidably connected. By using the door shoes 10 at the bottom of the door leaf 8 to slide on the door sill 101, the movement of the door leaf 8 is restricted from the bottom, making the structure more complete. The interior of the elevator car body 1 is fixed. The system is connected to a smart display screen 15 and a camera 16. The smart display screen 15 is electrically connected to a pressure sensor 9. The user receives data collected from the camera 16 and the pressure sensor 9 through multiple information processing modules inside the smart display screen 15. After the data is analyzed and processed, it is broadcast on the screen to provide real-time information and provide real-time reminders to the user. The system completes access control detection. The camera 16 performs real-time detection of the interior of the elevator car 1. When the pressure sensor 9 detects an abnormality, it transmits an electrical signal to the smart display screen 15 to trigger an alarm.

[0026] When a user enters the elevator, the user receives data collected from the camera 16 and pressure sensor 9 through multiple information processing modules inside the smart display screen 15. After analyzing and processing the data, it is broadcast on the screen to provide real-time information and reminders to the user. After completing the access control detection, the elevator starts working. The variable frequency motor 301 outputs power to the drive shaft 302, causing the drive shaft 302 to rotate, which in turn drives the drive turntable 303 to rotate, thereby rotating the belt 4. The belt 4 drives the driven turntable 501 to rotate, which in turn causes the shaft 502 to rotate with the driven turntable 501, thus rotating the chain 503. The chain 503 drives the door clamping knife 601 to move linearly. The clamping door knife 601 causes the door hanging plate 602 and the door leaf 8 to move together, and the pulley 603 slides on the guide rail 7, so that the door leaf 8 moves along the guide rail 7. The door shoe 10 at the bottom of the door leaf 8 slides on the door sill 101, restricting the movement of the door leaf 8 from the bottom, making the structure more complete. When the pressure sensor 9 detects an abnormality, it transmits an electrical signal to the intelligent display screen 15 to perform alarm processing and drive the components to brake urgently to avoid injury to personnel. At the same time, trapped personnel can manually open the mechanical lock 12 to release the fixation of the moving door panel 11, push the moving door panel 11, and make the gear 13 rotate, driving the moving door panel 11 to move linearly along the rack 14 until the exit opens, so as to achieve safe escape.

[0027] Through the above steps, a movable door panel 11, in conjunction with multiple components, is set up to create a manually operable mechanical emergency exit. In the event of a power outage or system failure, this ensures timely evacuation of personnel and avoids the risk of being trapped due to electronic system failure. At the same time, rescuers can directly and quickly open the hall door through the mechanical device, reducing demolition time, speeding up the rescue operation, avoiding delays in professional rescue due to electronic access control locks, and reducing the risk of secondary accidents. It is also compatible with multiple functions of smart access control, combining intelligence and redundant security to solve the problem that traditional elevator hall access control detection devices lack mechanical emergency exits, delaying rescue opportunities, reducing rescue efficiency, and even causing serious safety accidents.
