Description

Technical Field

[0001] This utility model relates to the field of security access control technology, specifically an arc-shaped rotating telescopic high-security AB door access gate. Background Technology

[0002] To enhance security, security turnstiles are installed at train stations, bus stations, and building entrances. Existing security turnstiles, including tripod turnstiles, swing gates, and sliding gates, all have limitations. Tripod turnstiles use a rotating mechanical barrier, which can prevent tailgating, but the small spacing between the gate arms can easily cause luggage to get stuck, and they cannot meet the needs of large items. Swing gates create a dynamic protective zone during opening, occupying 30-50% of the passage space, reducing the effective passage width, and the swing angle affects the opening and closing speed. While sliding gates solve the problem of excessively large dynamic protective zones, the parallel telescopic mechanism of the gate increases the equipment width by 40-60%, seriously affecting space utilization and aesthetics. Existing anti-pinch systems mostly use single-point infrared sensors with a response time >50ms, failing to meet the anti-pinch performance requirements of the EN12453 standard. Anti-tailgating monitoring relies on single-modal sensors, resulting in a 20-30% false alarm rate, and cannot identify new tailgating behaviors such as crossing gates. Utility Model Content

[0025] To enhance understanding of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described and introduced below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this utility model, not all embodiments, and are not intended to limit the embodiments in any way. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Please see Figure 1-11 This utility model provides a technical solution: an arc-shaped rotating telescopic high-security AB door access gate, including a dual-channel gate, which is composed of two symmetrical single-sided gates. Each single-sided gate is composed of a control head 1, a gate control body 200, and a tail 300. The two single-sided gates are symmetrically arranged to form a dual-channel control structure, and the symmetrical arrangement of the two channels forms a complete channel. Both the control head 1 and the tail 300 are equipped with touch screens and control systems, and passage indicator lights 130. An emergency door opening button 310 is installed inside the tail 300. Pressing the emergency door opening button 310 can quickly cut off the power and open the door in dangerous situations, facilitating rapid passage. The door control unit 200 is provided with a lower chassis left panel 2001, a lower chassis protective panel 2002, a lower chassis right panel 2003, an upper chassis 2004, a lower chassis, an arc-shaped door 230, a door control unit base plate 240, and a door control unit column 250, which are combined to form the door control unit 200 frame structure. The door control body column 250 is equipped with a motor maintenance plate 2501 and a side maintenance plate 2502. Inside the motor maintenance plate 2501, a DC servo motor 260, a lower chassis slide rail module 282 and a lower arc-shaped slide rail module mounting bracket 270 are installed. The lower chassis slide rail module 282 is equipped with a synchronous pulley 2821, a synchronous idler wheel 2822, a synchronous belt 2823, a belt connector 2824, a crank arm linkage mechanism 2825, and a lower slide block connector 2826. The upper chassis 2004 has a side indicator light 20042 on its side end. The upper chassis 2004 is equipped with an upper arc-shaped slide rail module mounting bracket 2852. Arc-shaped slide rail modules 283 are installed in both the upper chassis 2004 and the lower chassis.

[0027] The left protective explosion-proof glass 2005 and the right protective explosion-proof glass 2006 are fixedly connected to both sides of the lower chassis protective panel 2002 by pressure plates, which serves a protective function. The left protective explosion-proof glass 2005 and the door control body column 250 are provided with a gap to allow the curved door 230 to pass through when running. The left panel 2001 and the right panel 2003 of the lower chassis are fixed to both sides of the lower chassis protective panel 2002 by screws for installation and maintenance. The upper chassis 2004 is provided with an upper chassis maintenance panel 20041. The upper chassis maintenance panel 20041 is provided with an upper chassis slide rail module 281. The lower chassis protective panel 2002 is provided with an arc-shaped clearance groove, and its radius of curvature matches the arc trajectory of the curved door 230 and the arc-shaped slide rail module 283, so that the curved door 230 can move smoothly along the arc-shaped clearance groove, thereby opening or closing the curved door 230.

[0028] A synchronous belt pulley adjustment device 271 is fixedly connected to the top of the lower arc-shaped slide rail module mounting bracket 270. The door control body base plate 240 is fixedly connected to the mounting lower chassis slide rail module 282 by screws. The synchronous pulley 2821 is connected and fixed to the DC servo motor 260 on the lower arc-shaped slide rail module mounting bracket 270. The DC servo motor 260 is equipped with a torque sensing module to realize automatic retraction when encountering resistance. The synchronous idler wheel 2822 is fixedly connected to the synchronous belt pulley adjustment device 271. When the arc-shaped door 230 is rotating and closing, after the rotating door 230 clamps the object, the torque sensing module senses the pressure and automatically retracts. When the arc-shaped trajectory of the arc-shaped door 230 contacts the obstacle, the contact force is decomposed into a sliding component along the tangent direction of the door and a squeezing component perpendicular to the door through the arc surface of the radius of curvature, so as to avoid the arc-shaped door 230 forming a rigid clamp between the obstacle and the obstacle.

[0029] The synchronous idler wheel 2822 is connected to the synchronous belt 2823 via the belt connector 2824. The synchronous belt 2823 is connected to the synchronous idler wheel 2822 and the synchronous pulley 2821. The crank arm linkage mechanism 2825 is connected and fixed to the lower slider connector 2826. The other end of the crank arm linkage mechanism 2825 is also fixed to the belt connector 2824 to form a transmission mechanism. The arc-shaped slide rail module 283 consists of an arc-shaped slide rail 2831 and a slider 2832. The central angle of the arc structure of the arc-shaped slide rail module 283 is less than 90°. The arc-shaped slide rail 2831 is fixed on the lower arc-shaped slide rail module mounting bracket 270. The lower slider connector 2826 is fixedly connected to the side end of the slider 2832. Through the eccentric design of the arc center of the arc-shaped door body and the drive shaft, the clamping force application point is dynamically offset with the movement trajectory of the door body, avoiding the formation of a fixed clamping point in the closed position.

[0030] A DC servo motor 260 drives a crank arm linkage mechanism 2825 via a synchronous pulley 2821 to form the lower chassis drive mechanism. The synchronous belt 2823, crank arm linkage mechanism 2825, and arc-shaped slide rail module 283 are matched together and, in conjunction with a pre-set arc-shaped guide rail, convert the rotational motion of the arc-shaped door 230 into arc-shaped telescopic translation. The lower slide block connector 2826 is fixedly connected to the lower end of the arc-shaped door 230 with screws, and the upper end of the arc-shaped door 230 is fixedly connected to the upper slide block connector 286 with screws. The door control body 200 is equipped with a right-symmetrical arc-shaped door 230, made of stainless steel or glass, with a central angle of less than 90°. When closed, the arc-shaped door 230 forms a continuous physical barrier; when open, it retracts into the chassis. The clear width of the passage is not less than 1.2 meters, meeting the needs of large luggage passage. The arc height of the standard arc-shaped guide rail is less than the width of the chassis, achieving 80% clearance through optimized guide rail layout. To maximize the utilization of chassis space, the drive system adopts a standard arc-shaped guide rail and synchronous pulley-crank arm connecting rod combination transmission structure, combined with DC servo motor and closed-loop control strategy, to achieve rapid response of door movement and millimeter-level positioning accuracy.

[0031] The curved door body 230, the upper slider connector 286, and the lower slider connector 2826 are all provided with corresponding mounting holes and matching curved surfaces. The upper and lower ends of the curved door body 230 are connected to the door control body 200 through guide rails, forming a three-point support linkage structure in the vertical and horizontal planes to ensure that the curved door body 230 runs smoothly along the preset curved trajectory.

[0032] like Figure 9 and 10As shown, the lower part of the door control unit 200 is equipped with a matrix infrared light curtain protection system B1 / B2 / B3 / B4, and the upper part is equipped with millimeter-wave radar safety protection systems D1 and D2. The control head 1 and the tail 300 are equipped with supercapacitor modules for emergency door opening in case of fire or other dangerous situations. The control head 1 is equipped with an integrated multimodal recognition module 120, which adopts face and fingerprint recognition modes, and has a more advanced recognition function to avoid recognition problems. The control head 1 is equipped with a matrix infrared light curtain protection system A1 / A2 and an audible and visual passage indication alarm system, a front indicator light 2 and a 7-inch touch screen 140. The tail 300 is equipped with a matrix infrared light curtain protection system C1 / C2, an audible and visual passage indication alarm system and a tail light 320. The matrix infrared light curtain and millimeter-wave radar monitor the passage area to prevent people from taking the opportunity to break through the gate.
