Other AbstractThe invention provides an electric-hydraulic mixed power cylinder, belonging to the field of electromechanical technology the oil cylinder comprises a servo motor, a bidirectional constant rate pump, a hydraulic control check valve, a sensor, a hydraulic cylinder and an oil tank, wherein, the servo motor is connected with the bidirectional constant rate pump by a coupler the bidirectional constant rate pump is connected with two chambers of the hydraulic cylinder the oil tank is communicated with the hydraulic cylinder oil passage by the hydraulic control check valve the sensor is arranged on the hydraulic cylinder the oil cylinder is characterized in that: the oil tank is a concave structure component provided with hollow chambers where oil is arranged a concave trough of the concave structure component is internally provided with the coupler which is used for connecting the servo motor and the bidirectional constant rate pump. The oil cylinder has simple mechanical structure, integrates an installation part of the servo motor, an installation part of the constant rate pump, an installation part of the hydraulic control check valve and the oil tank into one part, has compact structure, and overcomes the shortage that each part in the prior art needs an installation part for fixing owing to the compact and simple structure, the oil cylinder has low manufacture cost, small mass, small space occupation and convenient transportation.
