Positioning buffer structure of driver's door of bus
A positioning buffer structure of a driver's door of a bus belongs to the technical field of buses and overcomes the problems in the prior art that the operating force of closing the driver door is increased in order to reduce noise, which affects the operation flexibility of the driver door, and that the existing buffer block can only provide outward pressure and cannot provide inward pulling force, which is not suitable for positioning buffer of the driver's door of the bus, wherein the left side of a first door frame column is provided with a C-shaped groove with an open end at the left, the C-shaped groove is installed with a positioning buffer bar, the main body of the cross section of the positioning buffer bar is a C-shaped open ring with a lower end opening, a first protrusion, a second protrusion, a third protrusion and fourth third protrusion are provided on the outer circumference of the C-shaped open ring of the positioning buffer bar, and the first door column is providedwith a round head protrusion matching the inner circle of the C-shaped open ring. The invention has the beneficial effect of not only improving the suppression of vibration shock between a lock tongueand a lock hole and reducing noise, but also not increasing the operating force of closing the driver's door, and not affecting the operation flexibility of the driver's door.
一种公交车司机门定位缓冲结构，属于公交车技术领域，克服了现有技术为了降低噪音增大了关闭司机门的操作力，影响司机门操作灵活性以及现有缓冲块只能提供向外侧的压力，不能提供向内侧的拉力，不适合公交车司机门定位缓冲的问题，特征是在第一门框立柱的左侧设有下端开口的C型凹槽，在C型凹槽内安装有定位缓冲条，定位缓冲条的截面主体部分为下端开口的C型开口圆环，在定位缓冲条的C型开口圆环外圆周上设有第一凸起、第二凸起、第三凸起和第四凸起，在第一门立柱上设有与C型开口圆环的内圆配合的圆头凸起，有益效果是既能提高对锁舌和锁孔之间的振动冲击的抑制作用,降低噪音，又不增大关闭司机门的操作力，不影响司机门操作的灵活性。
