Description

Technical Field

[0001] The utility model relates to the technical field of infrared touch screens, in particular to an angle-adjustable infrared touch frame. Background Art

[0002] The infrared touch frame is an advanced touch technology that uses infrared sensing technology to achieve touch function without physical contact. The working principle is to install an outer frame in front of the display, in which a circuit board is designed, so that infrared transmitting tubes and infrared receiving tubes are arranged on the four sides of the screen, one by one corresponding to form a horizontal and vertical infrared matrix. After each scan, if all infrared pairs of tubes are connected, the green light is on, indicating that everything is normal. If the infrared is blocked by the touched object, the infrared receiver will receive less line signals. By calculating the position where the touched object blocks the infrared signal, the position coordinates can be determined. The touch screen controller will analyze the received infrared signal and convert it into the touch position on the screen.

[0003] For example, an infrared touch frame with a publication number of CN213582136U and an authorization announcement date of 20210629 includes a frame body, an active infrared intrusion detector, a cover plate, a rotating frame and an adjustment rod; an active infrared intrusion detector is inlaid and installed on the front side of the inner circle of the frame body, mounting blocks are fixedly installed at both ends of the top of the frame body, and a cover plate is rotatably installed between the mounting blocks through an axle rod, a rotating frame is provided at the bottom of the frame body, and the two ends of the rotating frame are rotatably connected to the central positions on both sides of the frame body, an adjustment rod is fixedly installed at the central position of the bottom of the rotating frame through a threaded seat, a fixed screw sleeve is fixedly installed at a position near the bottom end of the surface of the adjustment rod, and a splint is sleeved on the surface of the adjustment rod. The utility model is provided with a cover plate, and after use, the cover plate can be rotated to clamp on the front of the frame body, so that the touch screen installed inside the frame body can be protected to prevent the touch screen from being damaged by the outside world.

[0004] In the prior art, the sensing position of the infrared touch frame is exposed to the outside world. If an accidental touch occurs or a mosquito flies towards the touch screen, it is easy to cause an error signal on the touch screen. The above-mentioned comparative document uses a cover to protect the touch screen, but the cover needs to be repeatedly opened and closed during use, which is troublesome to operate.
