Description

Device for quick locking and multifunctional communication connection of vehicle-mounted portable tablet personal computer Technical Field The invention belongs to the field of vehicle-mounted electronic equipment installation, relates to a design technology for quickly installing, reliably locking and synchronously realizing power supply and multichannel data communication of a portable reinforcement panel in a vehicle, and particularly relates to a device for quickly locking and connecting a vehicle-mounted portable panel. Background With the rapid development of intelligent cabins and vehicle-mounted informatization systems, the reinforced portable tablet is widely applied to the fields of special vehicles, engineering vehicles, police/military vehicles, logistics transportation and the like, and is used for key tasks such as navigation, task scheduling, video monitoring or man-machine interaction. In the ground control, emergency command, field exploration and other mobile operation scenes of the unmanned aerial vehicle, an operator often needs to hold a flat plate outside the vehicle to execute flight control, real-time image transmission or situation sensing tasks, and after the tasks are finished, the flat plate is put back into the vehicle to charge, synchronize data or stand by, so that a typical vehicle-machine cooperative working mode is formed. The application provides double challenges for the vehicle-mounted installation mode of the flat plate, namely, on one hand, the flat plate needs to be frequently disassembled and assembled, an installation structure is required to support rapid deployment and one-hand picking and placing, and on the other hand, in the running process of the vehicle, the flat plate needs to be firmly fixed, stable power supply and multi-channel data communication can be continuously provided, and the stable power supply and multi-channel data communication comprises high-speed data uploading, high-definition video feedback, equipment state feedback and the like. However, the current mainstream practice is still to place the tablet in a drawer or storage compartment under the instrument desk and manually connect to the vehicle interface through USB or Type-C data lines. This approach has the following significant drawbacks: (1) Each time of access, cables are required to be plugged and unplugged, the operation is complex, and quick scene switching of 'placing, locking and taking out, namely using' cannot be realized; (2) The common cable interface is easy to loosen or even fall off in a vehicle vibration environment, so that power supply interruption or communication failure is caused; (3) Only can support a single function (such as charging or low-speed data), and is difficult to simultaneously meet the multi-channel integrated transmission requirements of power supply, control signals, high-definition video and the like; (4) The drawer is lack of a special limiting structure, the flat plate is easy to slide and collide, and the risk of equipment damage exists; (5) The method does not support one-hand operation, and seriously affects task response efficiency in emergency running or rapid transition. Although some vehicle-mounted brackets in the market have a mechanical clamping function, the electric connection of the vehicle-mounted brackets still depends on an external wiring cable, and synchronous integrated butt joint of mechanical locking and multifunctional communication cannot be realized. The prior art lacks a quick docking device specially designed for high-frequency and high-reliability mobile operation, and can automatically establish a composite connection path comprising a power supply, data and video while ensuring stable structure. Disclosure of Invention The invention discloses a device for quickly locking a vehicle-mounted portable tablet and realizing multifunctional communication connection, which aims to solve the technical problems that a vehicle-mounted portable tablet in the prior art is not firm in fixation, electric connection depends on an external cable, is complex in operation, cannot quickly switch task scenes and the like in the accommodating and using process, so as to realize the purpose of meeting the comprehensive requirements of high-efficiency man-machine coordination, seamless task switching and vehicle-mounted environment adaptability in front application scenes such as unmanned aerial vehicle control and the like. Specifically, two sides of the body of the portable flat plate are symmetrically provided with a locking matching part and a guiding matching part, and the middle part of the bottom surface of the body is provided with an electric connection contact group; The fixed base is arranged in the movable carrier, a guide positioning piece, an elastic contact assembly and a locking mechanism installation area are arranged on the fixed base, and the guide positioning piece is matched with the guide matching part; The locking mechani
