Description

Technical Field

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

[0002] The arc-shaped rotating telescopic high-security AB gate access control system is a pedestrian access control device specifically designed for high-security locations such as airports, subways, and rail transit hubs. It typically employs an arc-shaped gate structure and an electromechanical integrated drive system, offering both efficient passage and high security. With the increasing demands for intelligence, integration, and space utilization efficiency in security access control technology, some access control systems have incorporated modules such as biometrics and infrared sensors to enhance both passage efficiency and security levels.

[0003] In practical applications, to balance traffic efficiency and spatial layout, sliding or rotating gate designs are often used in turnstile structures to achieve rapid opening and closing and effective closure of passageways. However, traditional turnstiles have obvious limitations in structural design: for example, the spacing between the gate arms of tripod turnstiles is small, which can easily cause luggage to get stuck; swing gates have a large swing angle and occupy a lot of space; while sliding gates solve the problem of excessively large dynamic areas, they significantly increase the width of the equipment and reduce space utilization. In addition, existing security protection systems mostly use single-point sensors, resulting in long anti-pinch response times and high false alarm rates for anti-tailgating monitoring, making it difficult to meet the real-time and accuracy requirements of high-security locations. At the same time, traditional turnstiles lack effective linkage with fire protection systems and security platforms, have limited identity recognition functions, and are not sufficiently intelligent. Summary of the Invention

[0004] The purpose of this invention is to provide an arc-shaped rotating telescopic high-security AB gate access control to solve the prominent problems of existing technologies in terms of structure, safety and intelligent linkage, and improve the applicability and reliability of access control in complex and high-density environments.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an arc-shaped rotary telescopic high-security AB door access gate, comprising two single-sided gates symmetrically arranged to form a dual channel, wherein each single-sided gate comprises a detachably connected control head, a gate control body, and a tail. The gate control body includes a frame structure, an arc-shaped gate body, and a drive mechanism; The drive mechanism includes a DC servo motor installed in the lower chassis of the door control unit, a synchronous pulley mechanism consisting of synchronous pulleys, synchronous idlers and synchronous belts, and a crank arm linkage mechanism; The output shaft of the DC servo motor is connected to the synchronous pulley, and the synchronous belt is fitted on the synchronous pulley and the synchronous idler wheel. One end of the crank arm linkage mechanism is fixedly connected to the synchronous belt through a belt connector. The door control unit is also equipped with an arc-shaped slide rail module, which consists of an arc-shaped slide rail and a matching slider. The other end of the crank arm linkage mechanism is hinged to the lower slider connector, and the lower slider connector is fixedly connected to the slider. The lower end of the arc-shaped door is fixedly connected to the lower slider connector, and the upper end of the arc-shaped door is fixedly connected to the slider of another arc-shaped slide rail module located in the upper housing of the door control unit through the upper slider connector.

[0006] Preferably, the frame structure of the door control unit is assembled from the door control unit base plate, door control unit columns, lower chassis left panel, lower chassis protective panel, lower chassis right panel, and upper chassis.

[0007] Preferably, the lower chassis protective panel is provided with an arc-shaped clearance groove, and the radius of curvature of the arc-shaped clearance groove matches the movement trajectory of the arc-shaped door.

[0008] Preferably, the upper and lower ends of the arc-shaped door are connected to the upper and lower arc-shaped slide rail modules respectively through the lower slider connector and the upper slider connector, forming a three-point support linkage structure, so that the arc-shaped door can move smoothly along the preset trajectory of the arc-shaped slide rail.

[0009] Preferably, the drive mechanism further includes a lower arc-shaped slide rail module mounting bracket fixedly mounted on the bottom plate of the door control body. The DC servo motor, synchronous pulley, and synchronous belt pulley adjustment device are all mounted on the lower arc-shaped slide rail module mounting bracket, and the synchronous idler wheel is mounted on the synchronous belt pulley adjustment device.

[0010] Preferably, the DC servo motor integrates a torque sensing module, which is used to trigger automatic retraction when the arc-shaped gate encounters resistance during operation.

[0011] Preferably, the control head integrates a multimodal biometric module, a touch screen, a main control module, and a matrix infrared light curtain protection system.

[0012] Preferably, the tail section integrates an emergency door opening button, an anti-tailgating matrix infrared light curtain sensor, and a supercapacitor module for opening the door after a power failure.

[0013] Preferably, the door control unit also integrates a matrix infrared light curtain for anti-pinch protection and a millimeter-wave radar for anti-tailgating monitoring.

[0014] Preferably, the arc height of the arc-shaped slide rail is less than the width of the door control unit chassis.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes an arc-shaped rotating telescopic mechanism, which allows the door to retract completely into the chassis after opening, greatly satisfying the barrier-free passage requirements for large luggage in airports, subways, and other locations. At the same time, the compact layout of the arc-shaped guide rail, with an arc height less than the width of the chassis, improves the overall space utilization of the equipment compared to traditional sliding gates and swing gates, effectively saving installation space.

[0016] 2. This invention uses a DC servo motor in conjunction with a synchronous pulley and a crank arm linkage transmission structure for the drive mechanism, and achieves precise control through a closed-loop control system, which shortens the opening and closing time of the gate and improves the passage efficiency compared with traditional turnstiles, effectively alleviating the pressure on personnel passage during peak hours.

[0017] 3. This invention integrates a dual anti-pinch system consisting of a matrix infrared light curtain and door resistance and motor torque sensing. The anti-pinch response time is fast, and the safety performance meets the standards. Combined with the matrix infrared light curtain and millimeter-wave radar, the channel is monitored in three dimensions, which effectively identifies tailgating, gate crossing and other behaviors, with a low false alarm rate and significantly improves the anti-tailgating capability.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This invention provides a technical solution: in an embodiment of an arc-shaped rotating telescopic high-security AB gate access control, such as... Figure 1 As shown, an arc-shaped rotary telescopic high-security AB gate is disclosed, including two single-sided gates symmetrically arranged to form a dual channel. Each single-sided gate adopts a detachable modular design and consists of a control head 100, a gate control body 200 and a tail 300 that are detachably connected by fasteners.

[0031] like Figure 1 and Figure 9 As shown, the control head 100 integrates a multimodal biometric module 120, a 7-inch touch screen 140, a main control module, and a matrix infrared light curtain protection system A1 / A2. The front panel of the control head 100 is equipped with a front indicator light and a passage indicator light. It also has a supercapacitor module for opening the door when the power is off, which is used to maintain system operation in an emergency.

[0032] like Figure 2 , Figure 3 , Figure 4 As shown, the door control body 200 constitutes the main frame of the equipment, which is assembled from the door control body base plate 240, door control body column 250, lower chassis left panel 2001, lower chassis protective panel 2002, lower chassis right panel 2003 and upper chassis 2004. The door control unit 200 is equipped with symmetrical arc-shaped door bodies 230, made of stainless steel or glass, with a central angle of less than 90°. The left and right protective explosion-proof glass are fixedly installed on both sides of the lower chassis protective panel 2002 by pressure plates. A gap is reserved between the left protective explosion-proof glass and the door control unit column 250 to allow the arc-shaped door body 230 to pass through. An arc-shaped clearance groove is provided on the lower chassis protective panel 2002. The radius of curvature of the arc-shaped clearance groove matches the movement trajectory of the arc-shaped door body 230 and the arc shape of the arc-shaped slide rail module 283.

[0033] like Figure 5 As shown, the door control body 200 has an openable motor inspection plate and a side inspection plate on its door control body column 250 for installing and maintaining the internal drive mechanism; a lower arc-shaped slide rail module mounting bracket 270 is fixedly installed on the door control body base plate 240 by screws.

[0034] like Figure 7 As shown, the drive mechanism includes a DC servo motor 260, a synchronous belt pulley mechanism, and a crank arm linkage mechanism 2825. The DC servo motor 260 is fixedly mounted on the lower arc-shaped slide rail module mounting bracket 270 by bolts, and its output shaft is connected to the synchronous pulley 2821. The synchronous idler wheel 2822 is mounted on the synchronous belt pulley adjustment device 271, which is also fixed to the lower arc-shaped slide rail module mounting bracket 270. The synchronous belt 2823 is fitted onto the synchronous pulley 2821 and the synchronous idler wheel 2822. One end of the crank arm linkage mechanism 2825 is fixedly connected to the synchronous belt 2823 through the belt connector 2824, and the other end is hinged to the lower slide block connector 2826.

[0035] like Figure 6 As shown, the arc-shaped slide rail module 283 consists of an arc-shaped slide rail 2831 and a matching slider 2832; the arc-shaped slide rail 2831 is fixedly installed on the lower arc-shaped slide rail module mounting bracket 270, and the slider 2832 is fixedly connected to the lower slider connector 2826. The arc height of the arc-shaped slide rail 2831 is less than the width of the door control body 200 chassis; the lower slider connector 2826 is fixedly connected to the lower end of the arc-shaped door body 230 by screws.

[0036] like Figure 6 As shown, another set of arc-shaped slide rail modules 283 is installed in the upper housing 2004 of the door control body 200 via an upper arc-shaped slide rail module mounting bracket; the slider 2832 of this module is fixedly connected to the upper slider connector 286, and the upper slider connector 286 is then fixedly connected to the upper end of the arc-shaped door body 230 by screws, thereby forming a three-point linkage structure that supports the arc-shaped door body 230 together with the lower drive mechanism, so that it can move smoothly along the preset arc trajectory.

[0037] The DC servo motor 260 drives the crank arm linkage mechanism through the synchronous belt pulley to form the lower chassis drive mechanism. The synchronous belt pulley, crank arm linkage and arc slide rail module combined transmission structure, together with the preset arc guide rail, converts the rotational motion into the arc extension and translation of the door.

[0038] like Figure 9 As shown, the door control unit 200 also integrates matrix infrared light curtains B1 / B2 / B3 / B4 and millimeter-wave radars D1 / D2 for safety protection, which are respectively set in different positions in the channel area to achieve anti-pinch and anti-tailgating monitoring.

[0039] In a preferred embodiment of the method for implementing a high-safety AB gate access control with arc-shaped rotary telescopic movement, the trajectory of the motion mechanism is converted through an innovative synchronous pulley and crank arm linkage transmission mechanism a, which couples the rotational motion d of the arc-shaped gate 230 with the arc telescopic motion b / c, thereby achieving a fusion of efficient passage and high safety during the opening and closing of the arc-shaped gate 230 during telescopic translation d1 / d2 / d3 / d4.

[0040] The curved door 230 adopts a streamlined curved design, forming a continuous physical barrier when closed. When opened, it smoothly retracts into the upper and lower compartments of the equipment along the preset curved slide rail module 283 trajectory b1 / b2 / b3 / b4, ensuring unobstructed passage of large luggage and other wide items.

[0041] The drive system a, combined with the arc-shaped slide rail module 283, synchronous pulley, and crank arm connecting rod transmission structure, along with the DC servo motor 260 and closed-loop control strategy, achieves rapid response and millimeter-level positioning accuracy for the door movement. The standard arc-shaped guide rails set in the lower and upper housings of the door control unit, along with the arc shape of the door, are set as concentric circle central axes. The door can rotate around the central axes d1 / d2 / d3 / d4 and extend along the arc-shaped guide rails b1 / b2 / b3 / b4 along the extension trajectory c1 / c2 / c3 / c4, realizing the combination of rotation and extension conversion of the motion mechanism, and realizing the rotation, extension, and translation switch of the arc-shaped door.

[0042] like Figure 1 and Figure 2 As shown, the tail section 300 integrates an emergency door opening button 310, an anti-tailgating matrix infrared light curtain sensor C1 / C2, and a supercapacitor module for opening the door after power failure. Externally, it is equipped with a taillight 320 and a passage indicator light 130. The door control body 200 also integrates a matrix infrared light curtain for anti-pinch protection and a millimeter-wave radar for anti-tailgating monitoring.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
