Stepless limiting stopper and automobile
The invention relates to the technical field of limiters, in particular to a stepless limiter and an automobile, and aims to solve the problem that the automobile cannot be stopped at any position in the door opening and closing process. The stepless limiting stopper comprises a cylinder barrel and a switch valve, the switch valve is inserted into the cylinder barrel, the switch valve comprises a valve sleeve, a first valve element assembly and a second valve element assembly, and the first valve element assembly and the second valve element assembly are structurally symmetrical and symmetrically arranged on the two sides of the valve sleeve; the end, away from the second valve element assembly, of the first valve element assembly is a first cavity, and the end, away from the first valve element assembly, of the second valve element assembly is a second cavity. The first valve element assembly comprises a sliding sleeve unit, a reset spring and a fixing unit. The reset spring is used for applying elastic force to the sliding sleeve unit so that the sliding sleeve unit can abut against the fixing unit. The elastic force of the reset spring enables the first cavity and the second cavity to generate a pressure difference and balance the elastic force, and meanwhile the pressure difference acts on the section of the cylinder barrel to balance the load and achieve residence at any position.
本发明涉及限位器技术领域，尤其涉及一种无级限位器及汽车，旨在解决汽车开关门过程中不能实现任意位置停止的问题。本发明提供的无级限位器包括缸筒和开关阀，开关阀插装于缸筒，开关阀包括阀套、第一阀芯组件和第二阀芯组件，第一阀芯组件和第二阀芯组件结构对称并对称设置于阀套两侧；第一阀芯组件远离第二阀芯组件的一端为第一腔，第二阀芯组件远离第一阀芯组件的一端为第二腔；第一阀芯组件包括滑套单元、复位弹簧和固定单元，复位弹簧用于向滑套单元施加弹力以使滑套单元抵接于固定单元。复位弹簧的弹力使第一腔和第二腔产生压强差并平衡弹力，同时压强差作用于缸筒截面以平衡负载，实现任意位置的驻留。
