Arm mechanism for bathing robot, and bathing robot

Abstract

The invention discloses an arm mechanism for a bathing robot, and the bathing robot, belonging to the technical field of service robots. The bathing robot comprises a supporting base, a hydraulic cylinder and a lying plate assembly, wherein one end of the hydraulic cylinder is fixedly connected with the arm mechanism; a mounting shell is rotationally matched with a transmission assembly; a driving assembly is arranged between and is in sliding fit with the inner walls of the mounting shell; the driving assembly is meshed and matched with the transmission assembly; a connecting piece is in sliding fit with a first clamping assembly; a rotating sleeve is rotationally matched with a second clamping assembly; and the second clamping assembly is engaged and matched with a driving gear. According to the invention, the two ends of a towel are fixed to the two clamping assemblies correspondingly, and the towel is straightened under the acting force of connecting springs; a servo motor is started to drive the driving assembly to rotate, and meanwhile, under the acting force of a reset spring, the two clamping assemblies move back and forth to rub the back of a patient; and the driving motor is started to drive the second clamping assembly to rotate, so the towel is cleaned and wrung dry, and the back of a patient is wiped dry.

Description

technical field [0001] The invention belongs to the technical field of service robots, in particular to an arm mechanism for a bathing robot and a bathing robot.
