Description

Monitor transmission mechanism for synchronously driving three optoelectronic devices

This invention is about a monitor transmission mechanism that is suitable for synchronously driving three photoelectric devices in an industrial environment. In particular, it is a transmission mechanism that can make the overall size of the monitor more compact and concise compared with conventional similar products, and can drive three photoelectric devices. A monitor transmission mechanism that synchronously rotates the device in the first direction and/or the second direction.

With the progress of society and the development of science and technology, monitors have become a part of daily life and are widely installed in various places such as traffic intersections, homes, businesses, offices, and factories to monitor the environment and prevent potential accidents. .

Since a large part of the monitors are installed outdoors, the monitors are exposed to the sun, rain, wind and rain during long-term outdoor use, which can easily cause corrosion and damage to the monitors. In addition, outdoor sand, dust or other dirt can cause damage to the monitors. It is also easy to accumulate in gaps or lenses, thus affecting the use of the monitor. High-grade industrial monitors used in harsh environments are also required to have explosion-proof performance to prevent the monitor from being damaged when a strong explosion occurs in the industrial environment, thereby protecting the images captured by the monitor. Therefore, high-level industrial monitor transmission mechanisms that synchronously drive three optoelectronic devices generally install the monitor in a protective shell to prevent the monitor from being directly exposed to the sun and rain, being vandalized, or being affected by strong environmental explosions. .

In order to monitor the surrounding environment as widely as possible, most monitors have the function of rotating horizontally and vertically. In order to obtain clear images at night or in poor light conditions, some monitors are equipped with cameras and Infrared thermal imaging cameras (collectively, "photoelectric devices").
