[0002] With the rapid development of the social economy, the scale of the automobile transportation industry is growing larger and larger. Tailgates, which are hydraulic lifting and loading / unloading devices powered by onboard batteries and installed at the rear of trucks and various vehicles, can greatly improve the efficiency and convenience of loading and unloading as a vehicle-mounted loading and unloading tool. However, because tailgates require a large space to open or close, and the tailgates themselves are quite heavy, if operators mistakenly stand within the rotating area of ​​the tailgate during opening or closing, it can lead to injury, posing a safety hazard. Furthermore, existing tailgates lack complete mechanisms to prevent injury from being pinched.

[0003] Chinese Patent Publication No. CN211468596U discloses an electric opening and closing mechanism for a car tailgate, including a main body fixedly connected to the car tailgate. The main body includes a bracket and an outer cover surrounding the bracket. An electric telescopic rod is disposed inside the outer cover. One end of the electric telescopic rod is rotatably connected to the bracket, with the rotatable connection point set as a first rotatable stop point. The other end is rotatably connected to a connector, with the rotatable connection point set as a second rotatable stop point. The connector is fixedly connected to the tailgate. The electric telescopic rod is electrically connected to a controller. The tailgate and the car floor are rotatably connected via a pivot. This utility model uses an electric telescopic rod to assist in opening and closing the car tailgate. During the opening and closing process, not only is manual operation unnecessary, making operation convenient and quick, but it also effectively avoids injury from being pinched, showcasing the automated style of luxury cars and effectively improving the cost-effectiveness of automobiles. Although this patent avoids injury through the opening and closing mechanism, it does not detect the open or closed state of the tailgate or the surrounding environment. Incorrect operation may pose a safety hazard. Utility Model Content
