The technical problem to be solved by the utility model is that the traditional passenger door has large noise in the process of opening and closing, is not suitable for high and cold areas, the locking process is complex, and the locking failure is easy to occur. In order to solve the above problems, the utility model provides an electric external swing door of a passenger car, which comprises a door plate, which is installed with an electrically driven door pump assembly, a rotating shaft assembly driven by the door pump assembly and a rotating arm assembly driven by the rotating shaft assembly, wherein the door pump assembly, the rotating shaft assembly and the rotating arm assembly are connected with the controller. The utility model can work normally in various harsh environments, reduces the noise in the switching process, and is not easy to have locking failure.
At present, the traditional passenger door pump assembly is equipped with a cylinder to realize the opening and closing of the passenger door, and the air source must be used for connection. When the vehicle runs in high cold and high temperature areas, the reliability of the cylinder will deteriorate. The problem that the passenger door cannot be opened and closed often occurs, which is easy to cause damage to the door pump. In this structure, the passenger door needs to be lifted by iomm through the operation of the door pump during the closing process of the passenger door to complete the locking of the passenger door. In the corresponding opening process, the passenger door needs to be lowered by iomm through the operation of the door pump to unlock the passenger door. If there is a problem with the lifting device, the passenger door will also fail to open and close normally. In addition, with the change of customer requirements, there are more and more high-end buses. Passengers want a quiet and comfortable environment on the bus, but the deflation of the traditional passenger door in the process of opening and closing the door will produce great noise, which will have a very bad impact on customers.
