Description

Technical Field

[0001] The utility model belongs to the technical field of infrared sensors, and particularly relates to an angle-adjustable sensor. Background Art

[0002] Infrared sensors are widely used in many fields, including medicine, military, space technology, and environmental engineering. Different application scenarios may require different detection angles. For example, in military applications, infrared sensors may need to adjust the angle to detect targets in different directions. In environmental monitoring, the angle may need to be adjusted to cover a wider detection range. Existing infrared sensors usually do not have angle adjustment functions.

[0003] For example, a Chinese patent with publication number CN217818795U discloses an infrared sensor, including an infrared sensor body, a rectangular heat sink fixedly connected to the left outer surface of the infrared sensor body, an infrared emitting head fixedly connected to the rear end outer surface of the infrared sensor body, a fixed wiring port movably connected to the front end inner surface of the infrared sensor body, a threaded clamping piece fixedly connected to the rear end inner surface of the fixed wiring port, a threaded rotating piece threadedly connected to the inner wall of the threaded clamping piece, a circular stopper fixedly connected to the outer wall of the threaded rotating piece, and a connecting wire fixedly connected to the rear end outer surface of the fixed wiring port.

[0004] The above-mentioned infrared sensor cannot be adjusted in angle. When the angle of the infrared sensor cannot be adjusted, its detection range will be fixed at a specific angle, which means that the sensor can only detect targets within this angle range and cannot cover a wider area. Its flexibility in different application scenarios will be limited. Utility Model Content
