Description

Technical Field

[0001] This utility model relates to the field of infrared sensing technology, specifically to an infrared sensing device for fully automatic folding doors. Background Technology

[0002] Fully automatic roller shutters are a highly efficient entrance solution widely used in commercial and residential areas. They improve convenience and security by managing the opening and closing of the door through an automated control system. These doors are typically equipped with infrared sensors that use infrared technology to automatically detect objects or people approaching the door area, triggering the door to open or close.

[0003] While existing infrared sensing devices offer certain conveniences for automation, they also have significant limitations. The main problem is that once installed, the sensing area is fixed, and users cannot adjust the sensing range or direction according to actual needs. This fixed nature limits the flexibility and adaptability of fully automatic folding doors, especially when the sensing area needs to be adjusted according to different environmental conditions or specific scenario requirements.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4This utility model provides a technical solution: a fully automatic folding door infrared sensing device. The device includes an infrared light-transmitting cover 1, a back plate 2 fixedly installed inside the cover 1, and a support plate 3 fixedly installed at the lower end of the back plate 2. The support plate 3 has several through holes 4. The infrared light-transmitting cover 1 is connected to the support plate 3 via bolts passing through the through holes 4. The back plate 2 is connected to the wall via fastening bolts 5. Two brackets 6 are fixedly installed at the front end of the back plate 2. An infrared sensing device body 7 is rotatably mounted in the middle of the brackets 6. The lower surface of the infrared sensing device body 7 has a sensing surface 8 for emitting and receiving infrared signals. The angle of the sensing surface 8 can be adjusted by adjusting the components to adjust the sensing area. The infrared light-transmitting cover 1 protects the internal components from dust, moisture, and direct impact, ensuring accurate infrared transmission. Due to interference, the back plate 2, as the main support structure, provides a stable installation base for the infrared sensing device. The support plate 3 enhances the structural stability of the entire device and provides additional support for the back plate 2 and the infrared light-transmitting cover 1. The through hole 4 allows bolts to pass through to connect the support plate 3 and the back plate 2, achieving a stable structural connection. The bolts are used to fix the support plate 3 and the back plate 2 through the through hole 4, ensuring the stability and safety of the device. The fastening bolt 5 fixes the back plate 2 to the wall, providing stability and structural strength during installation. The two side brackets 6 provide support for the main body 7 of the infrared sensing device and allow the rotation rod 9 to be connected to adjust the angle of the sensing area. The rotation rod 9 serves as the axis connecting the two side brackets 6 and the main body 7 of the infrared sensing device, allowing the sensing device main body 7 to be angled. The sensing surface 8 captures infrared signals to detect and respond to moving objects passing through its sensing area.

[0025] The adjustment assembly includes a rotating rod 9. The infrared sensor body 7 and the two side supports 6 are rotatably connected via the rotating rod 9. A gear 10 is fixedly installed at the right end of the rotating rod 9. A bracket 11 is fixedly installed at the right end of the support 6. A knob 12 is rotatably installed at the right end of the bracket 11. A button 13 is movably installed at the upper end of the knob 12. A movable rod 14 is rotatably installed inside the knob 12. The gear 10 meshes with the teeth 15 on the movable rod 14 to transmit the adjustment force of the knob 12 to adjust the sensing angle. The knob 12 provides the user with an interface to manually adjust the angle of the infrared sensor body 7. By rotating the knob 12, the user can precisely control the direction of the sensing area. The movable rod 14 responds to the operation of the knob 12 through an internal mechanical connection.

[0026] A toothed buckle 15 is fixedly provided at the end of the movable rod 14 away from the button 13. The toothed buckle 15 meshes with the gear 10. A first spring 16 is provided between the button 13 and the movable rod 14. A second spring 17 is provided between the movable rod 14 and the inner wall of the knob 12. The movable rod 14 is fixed to the inner wall of the knob 12 by a rotating shaft 18. The toothed buckle 15 is located at the end of the movable rod 14 and meshes or disengages with the gear 10 to participate in locking or releasing the sensing angle. The button 13 controls the movement of the movable rod 14, allowing the user to release or lock the sensing angle by pressing the button 13. The second spring 17 causes the movable rod 14 to reset after the button 13 is released, ensuring that the toothed buckle 15 re-meshes with the gear 10 and maintaining the stability of the angle. The rotating shaft 18 provides a fulcrum for the movable rod 14, supporting its rotation or movement under the operation of the knob 12, thereby adjusting the angle of the sensing device.

[0027] Working principle: A back plate 2 is fixedly installed inside the infrared light-transmitting cover 1. The lower end of the back plate 2 is connected to the support plate 3 through the through hole 4 and bolts to achieve overall fixation. The back plate 2 is connected to the wall by fastening bolts 5 to provide installation stability. The two side brackets 6 at the front end of the back plate 2 are rotatably connected to the main body 7 of the infrared sensing device through the rotating rod 9, so that the sensing surface 8 can be oriented and adjusted to adjust the sensing area. During the adjustment process, the gear 10 at the right end of the rotating rod 9 and the toothed buckle 15 at the end of the movable rod 14 inside the knob 12 form a linkage. When the button 13 is pressed, one side of the movable rod 14... When the end is subjected to pressure, it moves towards the center, and one end of the movable rod 14 tilts up, causing the toothed buckle 15 to disengage from the gear 10. At this time, the angle of the infrared sensing device body 7 can be manually adjusted to change the sensing area. After releasing the button 13, the second spring 17 pushes the movable rod 14 to reset, causing the toothed buckle 15 to re-engage with the gear 10 to complete the locking. The rotating shaft 18 provides a rotation fulcrum for the movable rod 14. The support plate 3 is fixed by bolts through the through hole 4 to ensure the structural rigidity of the infrared light-transmitting cover 1 and the back plate 2. Finally, the precise engagement of the gear 10 and the toothed buckle 15 achieves the adjustment of the sensing angle and maintains the positioning stability.
