Movable lifting device comprising auxiliary travel system capable of adjusting rotating force

Abstract

The present invention relates to a movable lifting device comprising an auxiliary travel system capable of separately adjusting rotating force. Disclosed is a movable lifting device comprising an auxiliary travel system capable of adjusting rotating force, wherein the movable lifting device comprises: a base having a plurality of moving wheels; a lifting unit including a bed part on which a user lies, and an elevating frame which is coupled to the base and extends in an upward direction, wherein the elevating frame supports the bed part such that the bed part is located at a predetermined height or higher from the ground, and the elevating frame is arranged to selectively adjust the height of the bed part; an auxiliary travel unit including a driving wheel which is coupled to the base and which contacts the ground, and a driving motor for providing power to the driving wheel, the auxiliary travel unit selectively adjusting the rotating force of the driving wheel; and a control unit including a handle connected to the lifting unit so as to be gripped by a user, a sensor arranged on the handle to sense the working external force and transmit an electrical signal, and a control part for controlling whether to operate the driving wheel and rotating force of the driving wheel based on the electrical signal measured by the sensor.

Description

[0001] technology area [0002] The present invention relates to a mobile lifting device, in more detail, to a mobile lifting device with a driving assistance system with adjustable rotational force. The strength of the external force is used to change the rotational force of the driving wheel for assisting the travel of the lifting device. Background technique [0003] Recently, with the rapid increase of the elderly population, more interest has been shown in the research and development of age-friendly products that can improve user convenience and reduce the economic burden caused by medical care protection. [0004] The recuperation protection of the elderly is generally realized at home or in a nursing home for the elderly. In terms of self-care ability in daily life, the main behaviors are eating, bathing, defecating, and transferring and moving. [0005] In particular, elderly people who have limited mobility by themselves urgently need help from around them. It is...

Problems solved by technology

[0008] But for existing device, although when the user moves the bed that the person under guardianship rides, realizes the assistance to driving by the user, it is difficult for the user to adjust the driving speed and the rotational force of the driving assistance unit one by one. question

In particular, when climbing a sloping road, the user needs more strength due to the load on the bed, so there is a problem that it is difficult to control the driving speed and rotational force of the driving assistance unit accordingly.
