Abstract

The invention relates to an omni-directional rollator driven by mecanum wheels and relates to a rollator. The problems are solved that the mobility of a common wheelchair is low and great damage is caused to the health if a user sits on the wheelchair for a long time. Two mecanum wheels with built-in hub motors are arranged on the front side and the back side of a chassis, a pedal mechanism and aseat mechanism are arranged on the chassis, and a kneecap mechanism comprises a kneecap supporting plate, a pad plate, an adjustment block, an adjustment bending plate and a sliding sleeve; the pad plate is fixedly connected to the back surface of the kneecap supporting plate, one end of the adjustment block is fixedly connected onto the pad plate, the other end of the adjustment block is connected with the adjustment bending plate, and the adjustment block can move leftward and rightward perpendicular to the front and back direction; one end of the adjustment bending plate is inserted in thesliding sleeve and can move forward and backward, the sliding sleeve is fixedly arranged on a connection rod mechanism on the chassis, a chest protection mechanism comprises a chest protection plate and a handle, and the handle is fixedly connected to the back surface of the chest protection plate. The omni-directional rollator driven by the mecanum wheels is suitable for old people, disabled people, hemiplegia patients and lower limb paralysis patients who have difficulty in moving.

Description

technical field [0001] The invention relates to a rollator, in particular to an omnidirectional rollator driven by a mecanum wheel. Background technique [0002] At present, most of the elderly, the disabled, stroke hemiplegia patients and paralyzed patients with limited mobility generally need specialized personnel to take care of them in their daily life, and cannot take care of their normal daily life. The common mobility aids on the market generally include wheelchairs and electric wheelchairs. It helps travel to a large extent, but sitting in a wheelchair for a long time will lead to blood blockage, pressure sores, osteoporosis and other complications, which will have a great impact on health, and wheelchairs can be used in daily life such as toileting and moving in small spaces. inconvenience in life. Contents of the invention [0003] The present invention provides a mecanum wheel-driven omnidirectional rollator in order to solve the problems of low mobility of con...
