The invention discloses a joint energy storage adjustable device and a robot. The joint energy storage adjustable device comprises a joint load part, a joint output part, an output motor, an energy storage assembly, a gear assembly and a transmission assembly; the gear assembly comprises a spline shaft, a first spline connecting rod, a second spline connecting rod and a spline ring gauge; the first spline connecting rod is connected with the energy storage assembly, and the second spline connecting rod is fixedly connected with the joint output part; a second external spline, a first external spline and a third external spline are arranged at intervals in the axial direction of the spline shaft; the spline ring gauge and the spline shaft are coaxially arranged, and a first internal spline and a second internal spline are arranged at intervals; and the transmission assembly is connected with the spline ring gauge and can drive the spline ring gauge to move in the axis direction of the spline shaft. The transmission assembly can adjust the spline ring gauge to different positions, flexible adjustment of the joint energy storage adjustable device among an initial zero returning state, an energy keeping state, an energy storage state or an energy release state is achieved, and adjustability of the working state of the energy storage device is achieved.
Description
Technical field [0001] The present application relates to the field of robotics, in particular to a joint of the robot and the energy storage device is adjustable. Background technique [0002] In operation the robot joints required in the case of certain specific locations of speed and acceleration of a particular large force, the joint common way to increase the power source output force alone, but will significantly increase the mass and volume of the joint, will increase cost joints. In the conventional robot joint and, in specific locations, gravitational potential energy can not be saved, leading to energy loss. [0003] For this reason, in the related art, some of the joints of the robot is provided with an energy storage member, like the joint gravitational potential energy for storage. However, this related art, the compression spring energy storage member only immediately after the stored energy to release energy, for example, immediately after the release force of a co...
