摘　　要：针对目前主流的闭门器存在的问题,提出一种集门停、自动闭门、缓冲调速等功能为一体的自动闭门组合铰链。在设计自动闭门组合铰链基本结构的基础上,分析了它的工作原理,建立了自动闭门组合铰链与门组成的系统的物理模型和运动微分方程。为了使组合铰链运转平稳和速度可调,采用张力与速度调节机构分离的设计方法。这种方法使阻尼分支具有较大的空间容纳单向阀阀芯,增加单向阀的行程,进而提高速度调节的灵敏度,还能减少因弹簧储能和摩擦产生的热传递,降低液压阻尼机构的温度变化,提高自动闭门铰链的稳定性。文章对新型高性能闭门器的研究具有一定实用意义。This paper analyzes the present situation of door closure, and in the light of the existing problems at present, a new-style integrated hanges with door stop, automatic door closure, buffer and speed regulation and other functions is dveloped. On the design basis of the integrated hanges, this paper analyzes the operation principle and then establishes the physical model and kinematics differential equation of the system composed of integrated hanges and door. To acquire a smooth running and adjustable speed, the paper adopts separate design method for spring and damp- ing part. This method produces plenty of scope for the damping part to accommodate the disk of check valve, increases the stroke of check value and improves further the sensitivity for speed adjustment, as well as reduces spring energy storage and heat transfer cansed by friction, in consequence, reduces the change in temperature of hydraulic damping part and improves stability of integrated hanges. This paper may give the research on high-performance automatic door closers a practical significance.
