The invention discloses a dual-mode electric control shock absorber and a dual-mode control method, and relates to the field of shock absorbers, the dual-mode electric control shock absorber comprises a piston valve, a piston rod, a compression valve, a working cylinder and an oil storage barrel, the working cylinder is sleeved with the oil storage barrel to form a dual-barrel structure, the piston valve and the piston rod are arranged in an inner cavity of the working cylinder, and the piston rod is connected with and drives the piston valve through a valve assembly; the valve assembly comprises a low-pressure valve arranged on the piston valve in a sleeving mode and an electromagnetic valve fixed to the piston rod, a low-damping channel used for communicating the piston upper cavity with the piston lower cavity is formed in the valve assembly, and the low-damping channel is controlled by the ECU to be opened and closed. A plurality of piston throttling holes are formed in the piston valve, and a normally-opened high-damping channel is formed. The invention provides an electric control shock absorber technology with a built-in electromagnetic switch, requirements are set for a user through damping of a motion mode and a comfortable mode which are preset after adjustment, actual selection is provided, opening and closing of an electromagnetic valve are selected in a simple mode of a current switch, and adjustment of the damping is achieved.

    本发明公开了一种双模电控减震器及双模式控制方法,涉及减震器领域,包括活塞阀、活塞杆、压缩阀、工作缸和贮油筒,贮油筒套设在工作缸外形成双筒式结构,工作缸内腔置入活塞阀和活塞杆,活塞杆通过阀组件连接带动活塞阀;阀组件包括套设在活塞阀上的低压阀和固定在活塞杆上的电磁阀,在阀组件内设有用于连通活塞上腔和活塞下腔的低阻尼通道,该低阻尼通道并由ECU控制单元控制启闭;活塞阀上开设若干活塞节流孔,形成常开启的高阻尼通道。本发明提供一种内置电磁开关的电控减震器技术,通过调校后预置的运动与舒适两种模式的阻尼来为用户设定需求并供实际选择,采用电流开关的简易方式来选择电磁阀的开合,实现阻尼的调节。
