Abstract

The invention relates to an infrared camera mechanical structure, belongs to the infrared field, and solves the problems of high processing precision requirement and high cost brought by adoption of a cam focusing mechanism and lens barrel inner wall cylinder guiding by most infrared cameras. The infrared camera mechanical structure includes a lens cover, a pressing ring I, a lens I, a lens barrel, a pressing ring II, a lens II, a linear motor assembly, a guiding assembly, a force bearing plate, a rear cover, a detector seat, a detector, a wire protecting cover, a separation blade installation seat, a photoelectric switch seat, two photoelectric switches, a separation blade and a focusing lens seat. The linear motor assembly provides power drive for linear motion required by focusing of the infrared camera. The guiding assembly provides necessary linear guiding for linear motion required by focusing of the infrared camera. The infrared camera mechanical structure provided by the invention adopts a miniature linear motor to directly drive an axis linear drive mode of a focusing lens and adopts a linear motion pair formed by a guiding shaft and a linear bearing to complete focusing motion required by the infrared camera, completely gets rid of a traditional cam drive mode, and the manufacturing cost of the camera is substantially reduced.

Description

technical field [0001] The invention belongs to the field of infrared technology, and in particular relates to a mechanical structure of an infrared camera. Background technique [0002] Infrared technology is more and more applied to people's daily life, such as security monitoring, forest fire prevention, temperature monitoring, etc. Therefore, the use of infrared cameras is becoming more and more common, but traditional infrared cameras are Factors such as mechanical structure limitations and dependence on imported detectors make the cost of traditional infrared cameras high, which limits the application of infrared cameras. Most of them are in the military field, but rarely in the civilian field. If you want to further expand the application range of infrared cameras, you must reduce its production costs from all aspects. [0003] At present, most infrared cameras use a cam focusing mechanism. The processing of the cam focusing mechanism requires high precision, and the...
