Vehicle-mounted mobile video monitoring system based on streaming media technology

Abstract

The invention discloses a vehicle-mounted mobile video monitoring system based on streaming media technology, which comprises a video monitoring device and a mounting device fixedly connected to the top end of the video monitoring device, the outer wall of a connecting rod is movably sleeved with a sleeve, the side wall of the sleeve is fixedly connected with an auxiliary rod, and the tail end of the auxiliary rod is movably sleeved with a telescopic rod. The telescopic rod is pulled out to fix the buckle on the connecting rod of the automobile reflective mirror, the auxiliary rod and the telescopic rod can guarantee that the device and the reflective mirror are located in the middle of the windshield, repeated observation in a visual mode is avoided, and after fixing is completed, the installation base is pushed towards the windshield to be fixed. Because the telescopic rod is in a pulling-out state, the piston moves upwards through a traction rope until the piston blocks a channel. And in the movement process, the sealed size in the suction cup is reduced, air is exhausted, the telescopic rod and the reset spring can reset the piston, the size in the suction cup is increased, at the moment, the suction cup is in a sealed state, the air pressure difference is formed between the interior of the suction cup and the outside, and arrangement and installation are more stable.

AI Technical Summary

Problems solved by technology

[0003] During the installation process of the existing vehicle-mounted mobile video monitoring system based on streaming media technology, its installation position is strictly required, and it is usually installed in the middle of the windshield to avoid blocking the driver's line of sight. However, the current installation method is Finding the middle point by visual method requires repeated adjustments. There is no good auxiliary mechanism to clarify the position of the middle point, so that the installation position has a certain position offset due to visual reasons, which may affect the driving line of sight. At the same time, During the long-term fixation of the suction cup, there is a phenomenon of deflation. The existing suction cup cannot increase the fastness by means of external force. Over time, it is easy to fall off, and there is a certain safety hazard.
