Title: A Bus Door Starting Mechanism Abstract The invention discloses a bus door starting mechanism which includes a shell, a transmission shaft is penetrate-mounted on the shell, the upper end of the transmission shaft extends out of the shell and is connected with a connecting bar mechanism, the lower end of the transmission shaft is mounted on a bearing in the shell, the shell is internally provided with a bevel gear pair, the driven gear of the bevel gear pair is slidably connected with the transmission shaft, the outer diameter of the transmission shaft is sleeve-provided with a spring between the lower end of the driven gear and the bearing, a motor is horizontally arranged outside the shell, and the driving gear of the bevel gear pair is connected with the output shaft of the motor. In the invention, as the spring is arranged below the driven gear, in case of meeting barriers, the driven gear slides downwards along the transmission shaft to separate from the driving gear to realize self-protection, and therefore, the safety and reliability of the starting mechanism are improved. \1L 6---------- N_- ----------------
