Bed-chair integration robot based on omnidirectional mobile chassis

Abstract

The invention discloses a bed-chair integration robot based on an omnidirectional mobile chassis, belonging to the field of health care instruments. The bed-chair integration robot comprises a bed-chair conversion mechanism and a bed body, wherein the bed-chair conversion mechanism can move out or move in the bed body, and the bed-chair conversion mechanism comprises an integrated frame, a parallel mechanism, a linkage mechanism and an omnidirectional chassis mechanism. The integrated frame also comprises a chair frame, a leg bending frame, a back plate frame, a leg plate frame and a foot plate frame, wherein the relative movement among the frames is realized through the linkage mechanism composed of a plurality of electric pushing rods, and a bed-chair conversion function is realized; and the bottom of the chair frame is connected with the omnidirectional chassis mechanism through the parallel mechanism, so that the left and right rollover, the front and back inclination and the lifting and drop of the whole frame can be realized at the same time through the parallel mechanism. The omnidirectional chassis mechanism realizes the omnidirectional movement of the bed-chair conversion mechanism. According to the bed-chair integration robot, the conversion and separation combination among a bed and a chair can be realized. The bed-chair integration robot has a perfect bed-chair conversion function and a turning function, the safety and the comfort are greatly increased, and the structure is simple.

Description

technical field [0001] The invention relates to the field of health care equipment, in particular to an integrated robotic mechanical care device with both the function of turning over and the function of converting a bed and chair. Background technique [0002] Existing nursing beds are mostly provided with movable bed boards on the bed body to help patients sit up or change their lying positions, but their functions are relatively simple. Some products combine the functions of nursing beds and wheelchairs to improve the mobility of users, but most of them are less intelligent and their use is also subject to certain restrictions. There are also products that realize a simple auxiliary turning function to reduce the occurrence of bedsores, improve the breathing conditions of users during sleep, and reduce the work intensity of nursing staff. However, due to structural limitations, the range of motion of the turning bed board is very small, and the turning axis Located in t...
