The invention discloses an electro-hydraulic cylinder and belongs to the technical field of automobile parts. The invention aims to provide an electro-hydraulic cylinder which integrates an electric pump, a manual pump, an oil pipe and a hydraulic cylinder, not only can supply oil automatically, but also can realize the function of a hydraulic lifting system. A motor is arranged on the side face of a hydraulic cylinder body, a buffering blocking piece is installed between the motor and the hydraulic cylinder body, the side face of a pump body is fixedly connected with the side face of a U-shaped clamp at the lower end of the hydraulic cylinder, and a sealed self-oil-supply tank is installed between the motor and the pump body; the upper half part of the pump body is a self-oil-supply mechanism, and the lower half part is a pump body oil way; the pump body and the pump body protruding ring are integrated to form the whole pump body. The electro-hydraulic cylinder is developed, equivalently, an electric pump, a manual pump, an oil cylinder, a hydraulic cylinder and the like are integrated, and the electro-hydraulic cylinder has the advantages of being integrated, few in parts, low in management cost, easy to assemble, high in efficiency, small in occupied space, convenient to arrange a whole vehicle, light in weight and the like.

    一种电液缸,属于汽车零部件技术领域。本发明的目的是将电动泵、手动泵、油管和液压缸集成在一起,既能自供油,又能实现液压举升系统功能的电液缸。本发明的电机在液压缸缸体侧面,并且它们之间安装有缓冲阻隔件,泵体本体侧面与液压缸下端的U型夹侧面固定连接,电机与泵体本体之间安装有密封的自供油箱;泵体本体上半部分为自供油机构,下半部分为泵体油路;泵体本体与泵体突出环为一体,构成整个泵体。本发明开发电液缸,相当于将电动泵、手动泵、油缸及液压缸等集成在一起,具有集成化、零件少、管理成本低、装配简单、效率高、占据空间小、便于整车布置、质轻等优点。
