Description

Technical Field

[0001] This utility model relates to the field of gimbal camera technology, and in particular to a dual-side four-eye gimbal integrated machine structure. Background Technology

[0002] In current technology, with the popularization of surveillance technology, it is being applied to more and more fields. Currently, most conventional cameras on the market use single lenses. Considering the limitations of lens monitoring angle and distance, multi-lens cameras and pan-tilt cameras have emerged. A pan-tilt unit is a support device for installing and fixing cameras; it is divided into fixed and motorized types. Fixed pan-tilt units are suitable for situations with a small monitoring range. After installing the camera on a fixed pan-tilt unit, the camera's horizontal and vertical angles can be adjusted to achieve the best working posture, and then the adjustment mechanism can be locked. Motorized pan-tilt units are suitable for scanning and monitoring large areas. They can expand the camera's monitoring range. The high-speed movement of a motorized pan-tilt unit is achieved by two actuator motors. The motors receive signals from the controller for precise operation and positioning. Under the control signal, the camera on the pan-tilt unit can automatically scan the monitoring area or track the monitored object under the operation of the monitoring center personnel. However, currently, most pan-tilt cameras, when used outdoors for image acquisition, suffer from low visibility in foggy weather, which is detrimental to image acquisition and may result in inaccurate image data.

[0003] Chinese utility model patent application number 201921860495.X discloses a quad-lens pan-tilt camera based on thermal infrared technology, including a base, a mounting bracket on the upper part of the base, a pan-tilt head on the upper part of the mounting bracket, and a zoom camera, a fixed-focus wide-angle camera, a thermal infrared camera, and a laser supplementary lighting device mounted on the outer end of the pan-tilt head. The fixed-focus wide-angle camera is located below the zoom camera, the thermal infrared camera is located to the right of the zoom camera, and the laser supplementary lighting device is located to the lower right of the zoom camera. A rain shield is provided on the upper part of the pan-tilt head, and a sealing gasket is fixedly connected to the bottom of the rain shield. The sealing gasket is located on the upper part of the pan-tilt head and in contact with the pan-tilt head. However, this quad-lens pan-tilt camera based on thermal infrared technology lacks a cleaning structure for cleaning the lens, which makes it susceptible to the influence of dirt adhering to the lens surface, resulting in a decrease in the image quality of the device. Furthermore, the protection of the device is poor, relying solely on the rain shield placed on the upper part of the pan-tilt head. Utility Model Content
