The invention discloses an electric control shock absorber with a hydraulic buffering structure, a vehicle chassis and a vehicle, and relates to the technical field of vehicle chassis, the electric control shock absorber comprises a shock absorber cylinder body assembly, the shock absorber cylinder body assembly comprises a working cylinder, a middle cylinder and a shock absorber cylinder body, and the working cylinder, the middle cylinder and the shock absorber cylinder body are all cylindrical and are sequentially arranged from inside to outside; a first cavity is formed in the working cylinder, a piston rod and a hydraulic buffering mechanism are arranged in the first cavity, the hydraulic buffering mechanism comprises a hydraulic buffering sleeve and a hydraulic buffering piston assembly, the hydraulic buffering sleeve is arranged at the top end in the first cavity, and the hydraulic buffering piston assembly is arranged on the piston rod in a sleeving mode and can freely slide up and down. The hydraulic buffering piston assembly is matched with the hydraulic buffering sleeve at the limiting position. When the hydraulic buffer piston assembly is impacted, the hydraulic buffer piston assembly slides upwards along the piston rod and enters the hydraulic buffer sleeve at the limiting position to generate a nonlinear damping effect, so that damping force is improved, and impact noise is avoided.

    本发明公开了一种带液压缓冲结构的电控减振器、车辆底盘及车辆,涉及汽车底盘技术领域,其包括减振器缸体总成,减振体缸体总成包括工作缸、中间缸和减振器缸体,工作缸、中间缸和减振器缸体均呈圆筒状,且三者由内至外依次布置;于工作缸内形成有第一腔体,并于第一腔体内设有活塞杆和液压缓冲机构,液压缓冲机构包括液压缓冲套筒和液压缓冲活塞组件,液压缓冲套筒设置在第一腔体内顶端,液压缓冲活塞组件套设在活塞杆上且可自由上下滑动,液压缓冲活塞组件在极限位置处与液压缓冲套筒相配合;在受到冲击时,液压缓冲活塞组件沿活塞杆向上滑动,并在极限位置处进入液压缓冲套筒内以产生非线性阻尼作用,以此提升阻尼力,进而避免冲击噪音。
