Mechanical device for assisting the elderly to get up and down

Abstract

The invention provides a mechanical device for assisting old people to get up and down. The device includes a bed frame, a driving mechanism, a transmission mechanism, a leg plate one-way locking mechanism and a supporting rod resetting mechanism, and the bed frame includes a vertical plate, a floor plate, a bottom plate, a bed seat and a steering bearing; and the floor plate is connected with thevertical plate, the bottom plate is connected with the second end part of the vertical plate to form a bed body connection part, and the bed body connection part can be connected with an external bedbody. The driving mechanism is a power source of the device and adopts a turbine worm rod structure, and motor steering is controlled to control worm rod steering to realize the entire process of turning of a bed body and standing up and flat lying; the transmission mechanism uses a four-bar mechanism; the leg plate one-way locking mechanism uses meshing of a first one-way bearing, a cam, a gearand a rack to realize locking, and the rack moves under the action of motors to realize hooking and loosening of a hook; and in the mechanical stretching and lifting process of the supporting rod resetting mechanism, a seat plate can be always kept in a horizontal state to hold people to lift the people up.

Description

technical field [0001] The invention relates to the field of medical device manufacture and application, in particular to a mechanical device for assisting the elderly in getting up and down. Background technique [0002] The aging population in today's society is serious, and the number of elderly people has increased, making the comfort and happiness of the elderly life a hot topic. Many elderly people live alone, and because the physical condition of the elderly is generally poor, many of them have mobility problems. [0003] Nursing beds, auxiliary frames, lifting machines, etc. have been invented on the market for elderly people who have limited mobility but have a certain ability to take care of themselves. However, there are some problems. Large-scale promotion and use; although the cost of the auxiliary frame is low, its effect is relatively small and cannot solve the fundamental problem; the lift is suitable for the paralyzed elderly, but it cannot provide assistan...

Many elderly people live alone, and because the physical condition of the elderly is generally poor, many have mobility problems

[0003] Nursing beds, auxiliary frames, lifting machines, etc. have been invented on the market for elderly people who have limited mobility but have a certain ability to take care of themselves. However, there are some problems. Large-scale promotion and use; although the cost of the auxiliary frame is low, its effect is relatively small and cannot solve the fundamental problem; the lift is suitable for the paralyzed elderly, but it cannot provide assistance for the normal and healthy elderly, and there is no comfort at all. Older people are not applicable and therefore cannot be generalized
