A design method of a hinge closing hydraulic buffer comprises an oil cylinder, a piston rod, a piston, an energy storage spring and an oil seal, the oil seal divides an inner cavity of the oil cylinder into an oil-free cavity and an oil cavity located on the lower side of the oil-free cavity, the piston is located in the oil cavity, the energy storage spring is located in the oil-free cavity, and the piston divides the oil cavity into an upper oil cavity and a lower oil cavity. An oil passing channel communicated with the upper oil cavity and the lower oil cavity is formed in the oil plug rod, a valve needle capable of adjusting the oil passing amount of the oil passing channel is installed in the oil cylinder, the piston is movably installed on the piston rod, and the piston moves upwards along with the piston rod to be separated from the piston rod to form an oil passing gap communicated with the upper oil cavity and the lower oil cavity. The valve needle adjusts the oil passing amount of the oil passing channel along with downward movement of the piston rod, the rigidity of the energy storage spring is designed to adjust the oil cylinder rotating force needed for driving the piston rod to move upwards, and the shape and the position of the valve needle are designed to adjust the downward movement speed of the piston rod. The door opening is more labor-saving, the cost of the buffer is reduced, the structure is simple, and the practicability is high.
合页闭门液压缓冲器的设计方法，包括油缸，活塞杆、活塞、蓄能弹簧和油封，油封将油缸内腔分隔为无油腔和位于无油腔下侧的有油腔，活塞位于有油腔中，蓄能弹簧位于无油腔中，活塞将有油腔分隔为上油腔和下油腔，油塞杆上开设连通上油腔和下油腔的过油通道，在油缸内安装可调节过油通道过油量的阀针，活塞可活动的装在活塞杆上，活塞随活塞杆的向上运动而与活塞杆分开形成过油间隙联通上油腔和下油腔，阀针随活塞杆的向下运动而调节过油通道的过油量，设计蓄能弹簧的刚度以调节带动活塞杆向上运动所需的油缸转动力，设计阀针的形状和位置以调节活塞杆向下运动的速度。本发明使开门更省力，降低缓冲器的成本，结构简单实用性高。
