The utility model provides a multifunctional vehicle-mounted magnetic wireless charger, which relates to the technical field of magnetic wireless chargers, and comprises an adjusting mechanism, one side of the adjusting mechanism is provided with an auxiliary mechanism, the adjusting mechanism comprises a shell, the bottom end of the shell is provided with a bottom support, the bottom end of the shell is correspondingly contacted with the top end of the bottom support, and the bottom end of the shell is connected with the bottom end of the bottom support. A lead screw is arranged on the inner wall of the center of the bottom support, and the inner wall of the center of the bottom support is connected with the outer side of the lead screw in a penetrating and threaded mode. The screw rod is rotated and moves on the original basis by screwing the rotating handle, the top end of the screw rod is connected with the fixed disc, and the fixed disc is positioned at the center of the adsorption part, so that the height of the adsorption part in the shell is increased, and the distance between the adsorption part and the top side in the shell is shortened; therefore, the adsorption capacity of the mobile phone is improved, the mobile phone is immovable during jolting, the falling risk caused by vibration is fundamentally eradicated, and a safe driving environment is created for a driver.

This invention relates to the technical fields of tunnel safety control, intelligent transportation, vehicle-road cooperation, and tunnel safety early warning. Specifically, it relates to a tunnel active safety control system and method based on vehicle-road cooperation. Key technical points include: a multi-source data fusion module: integrating data from roadside equipment (including radar, cameras, and fiber optic sensors) and vehicle-mounted terminals to construct a four-dimensional perception network of people, vehicles, roads, and the environment; a dynamic risk assessment module: quantifying the probability of an accident (P) and collision energy loss (E) based on an equivalent traffic conflict number (ECN) model to achieve risk-level early warning; and a vehicle-road cooperative intervention module: triggering early warning and control strategies from both the roadside and vehicle perspectives through two-way communication between roadside smart guidance signs, information boards, and vehicle-mounted terminals. This invention improves the ability to respond to tunnel risks.
