Description

Technical Field

[0001] This utility model relates to the field of anti-pinch technology for folding doors, specifically to a fully automatic folding door sensor-based anti-pinch device. Background Technology

[0002] Folding door anti-pinch devices typically employ dual monitoring technology, combining infrared arrays and pressure sensors. This allows for real-time detection of obstacles (such as people or objects) in the door's movement path. Upon triggering a signal, the door pauses or reverses its movement within 0.5 seconds, effectively preventing pinching injuries. The system incorporates intelligent algorithms to distinguish between false triggers (such as insects or light interference) and automatically resets. It supports multiple sensitivity levels to adapt to different door weights and operating speeds. Equipped with a self-diagnostic function, it triggers an audible and visual alarm and locks the door in case of an anomaly.

[0003] However, existing anti-pinch devices using infrared sensors can create blind spots. When a person moves into a blind spot, the sensing structure cannot receive the sensing signal, which can still cause the person to be trapped. Although pressure sensors can assist, the pressure sensor needs to be pressed before it can control the drive component of the folding door to rotate, which can easily cause minor injuries to people. In addition, existing devices are usually not easy to disassemble after installation, making maintenance or replacement more troublesome. Utility Model Content

[0023] The above scheme allows the cover to be installed using a screw assembly via a flat screw hole, and the cover to be installed using a magnetic attraction via a first magnetic plate. The cover installation allows the induction structure to be installed, the card slot can be opened via a card block, the protective box can be slidably installed via the card slot, the power cord can power the whole system, the controller can control the operation of the induction structure and send signals to control the operation of the drive device, and the connecting wire can connect the controller to the induction component to achieve anti-pinch sensing.

[0024] In this embodiment, preferably, the sensing mechanism 106 further includes a protective box 204. A connecting line 203 is fixedly installed on one side of the protective box 204, and hook blocks 205 are fixedly installed on both sides of the protective box 204 away from the connecting line 203. The hook blocks 205 are movably installed in the slot 105.

[0025] The above solution allows for the installation of the sensing components via the protective box, and the connection between the hook and the slot allows for the installation of the protective box and the cover.

[0026] In this embodiment, preferably, a light-transmitting glass 206 is fixedly installed on the side of the protective box 204 away from the hook block 205, and an installation groove 301 is opened on the side of the protective box 204 near the hook block 205. A locking pin 302 is fixedly installed in the installation groove 301, and the locking pin 302 is fixedly installed in the locking hole 303.

[0027] The above solution allows microwaves to pass through the transparent glass and reach the human body, the mounting groove allows the cover to be installed, and the pins and holes ensure the cover remains stable after installation.

[0028] In this embodiment, preferably, the card hole 303 is opened on the side of the cover plate 304, the cover plate 304 is fixedly installed in the mounting groove 301, a notch 305 is opened on one side of the cover plate 304, and a second magnetic suction plate 306 is fixedly installed on the side of the cover plate 304 near the notch 305.

[0030] In this embodiment, preferably, a support plate 401 is fixedly installed inside the protective box 204, a microwave sensing module 402 is fixedly installed inside the support plate 401, and wires 403 are fixedly installed between the microwave sensing modules 402.

[0031] The above scheme allows the microwave sensing module to be installed on a support plate. The microwave sensing module emits microwaves, and the reflected microwave signals enable the controller to control the operation of the drive device. The microwave sensing modules can be connected in series via wires to complete power supply and signal transmission.

[0032] In this embodiment, preferably, the wire 403 is fixedly installed on the conductive block 404, the top of the conductive block 404 is fixedly installed with a connection point 405, and a connecting wire 203 is fixedly installed on the connection point 405.

[0033] The above scheme allows for the setting of connection points using conductive blocks, and the welding of connecting wires can be performed through these connection points.

[0034] In this embodiment, the fully automatic folding door anti-pinch device allows the user to select the installation method based on the door frame material. When the door frame can be magnetically attached, the user can use the first magnetic plate 103 to attach and fix the cover plate 304. When the door frame cannot be magnetically attached, the cover plate 304 can be fixed using flat screws installed through the flat screw holes 102. After the cover plate 304 is fixed, the user connects the protective box 204 and the cover plate 304 by connecting the hook block 205 to the slot 105. After connection, the first magnetic plate 103 and the second magnetic plate 306 attract each other, keeping the protective box 204 stable. At this time, the user connects the power cord 201 to the drive device on the folding door. After the controller 202 is powered on, it powers the microwave sensing module 402 through the connecting line 203. The microwave sensing module 402 emits microwaves at the folding door. When a person moves, the microwaves are reflected upon contact with the person and received by the microwave sensing module 402. At this time, the microwave reflection... The signal enters the controller 202 through the connecting line 203. The controller 202 adopts the structure in application number (201822132305.4 Microwave Induction Control Device). It can send control electrical signals according to the microwave reflection signal, thereby controlling the operation of the folding door drive device. Therefore, when a person moves, it will control the drive device to open the folding door. After the person leaves, when no reflection signal is received, the folding door will close. Similarly, during the closing process of the folding door, the controller 202 receives the microwave change signal and controls the drive device to drive in reverse, so that the closing folding door will open again before it pinches the person, thereby avoiding injury. When the component is damaged and needs repair or replacement, the hook block 205 can slide in the slot 105 by pulling the protective box 204, so that the protective box 204 can be quickly removed. At the same time, the cover plate 304 can be quickly removed through the slot 305 for repair and replacement inside the protective box 204.
