Description

Electric intelligent massage old-people-assisting wheelchair with liftable seat and supporting standing and walking

Technical Field

The invention belongs to the technical field of intelligent old people assisting instruments, and particularly relates to an electric intelligent massage old people assisting wheelchair with a liftable seat and capable of supporting standing and walking.

Background

Although China is at the early stage of aging, the aging is developed rapidly, so that the proportion of the elderly population is getting larger and larger. According to the national population statistical data of 2019 of the State administration of statistics, 157608 ten thousand of the existing old people in China are shown, wherein the number of people aged 65 and above is 17603 ten thousand, and accounts for 12.6% of the national population, which indicates that China has entered the aging social stage.

The multifunctional old-helping wheelchair is different from a common nursing wheelchair or a nursing bed, and is a product combining machinery and electronics. It can be placed in homes, nursing homes, hospitals to help the elderly to stand up, lift/lower the back, stretch/bend the legs, move freely, go to the toilet conveniently, and the like. The development of the multifunctional aging-assisting wheelchair can greatly relieve the huge pressure on the society caused by aging, so researchers in various countries around the world continuously research intelligent nursing mechanisms, and the intelligent nursing mechanisms are more humanized and intelligent.

However, the traditional medical nursing wheelchair has a single function, a low automation level and insufficient consideration of humanization, and requires cooperation of multiple persons for operation, so that the efficiency is low.

The use method of the electric intelligent massage old-age-assisting wheelchair with the liftable seat and the standing walking support provided by the invention is explained as follows:

when the elderly sits on the opening plate 7 of the wheelchair, the waist is first tightened with the belt 24, and the feet are put on the pedals 13.

When the elderly wants to adjust the height of the seat 1, the button on the controller for controlling the scissor-holder electric push rod 16-5 on the scissor holder 16 is pressed, and the scissor-holder electric push rod 16-5 is extended or retracted outward, and the slider 16-3 is moved backward or forward along the slide rail 16-2 by connecting the ear plate 16-4 and the scissor lever 16-1, thereby raising or lowering the upper frame 5 and its components.

When the elderly want to move, the user presses a button on the controller for controlling the large motor 54 on the damper wheel 18, and the damper wheel 18 rotates, thereby completing the forward, backward, turning, etc. movements of the wheelchair.

When the old people want to lie down, the button for controlling the back electric push rod 26 and the button for controlling the lower electric push rod 15 on the controller are pressed, at this time, the back electric push rod 26 will retract, thereby transmitting the pushing force to the back plate 23 through the L-shaped rod 27 and the straight rod 28, and tilting the back plate 23 back to the horizontal state; at the same time the lower power pusher 15 will be extended outwardly thereby raising the front end of the leg plate 11 to a level flush with the rear end.

When the old people want to do leg exercise, the binding band 21 is tightly tied on the legs of the old people, at this time, the old people can actively lift the legs to lift the lower part of the recovery plate 12, thereby stretching the tension spring, and after the legs are relaxed, the recovery plate 12 is restored by the pull-back force of the tension spring.

When the old people want to assist in going to the toilet, firstly, the buttocks are lifted slightly, then a button used for controlling the small motor 8 on the controller is pressed, at the moment, the small motor 8 rotates and drives the bottom gear 10 to rotate together, so that the two racks 9 and the two opening plates 7 are enabled to translate towards two sides, finally, the toilet opening 22 is exposed, then the old people sit on the seat plate 6, and the toilet can be directly placed below the toilet opening 22 or the wheelchair is controlled to move to the upper part of the toilet, and then the old people can go to the toilet.

When the old people want to assist standing and walking, a key used for controlling a standing electric push rod 17 on a controller is pressed, at this time, the standing electric push rod 17 extends outwards, so that a turning frame 5-2 rotates around a front frame strip of a fixed frame 5-1, components such as a seat plate 6, a split plate 7 and a back plate 23 are driven to rotate together until the standing electric push rod is in an upright state, in the process, the whole height of the seat 1 can be adjusted by using a scissor frame electric push rod 16-5, an included angle between a leg plate 11 and a horizontal plane is adjusted by using a lower electric push rod 15, a small universal wheel 14 below a pedal plate 13 is enabled to contact the ground, and the small universal wheel 14 is enabled to cooperate with a large universal wheel 19 and a damping wheel 18 to realize standing and walking of the old people.

When the sun shade 3 is too hot outdoors and needs to be used, a button used for controlling the top electric push rod 35 on the controller is pressed, at this time, the top electric push rod 35 extends outwards, the top sliding block 33 is pushed, the top sliding block 33 drives the top rack 32 to slide, the top gear 34 rotates through the matching of the top gear 34 and the teeth on the top rack 32, then the connecting rod 29 in a folded state is unfolded, and the umbrella cloth 30 is stretched out of the reel 31. Alternatively, the sunshade 3 can be opened and closed by manually pulling or pushing back the support plate 36 connected to one end of the sheet 30.

When the elderly people want to use the massage device 40, the controller is pressed to control the massage motor 42, and the massage motor 42 starts to rotate, so that the massage palm 45 is driven to rotate eccentrically through the worm gear 43 and the back gear 44, and the back of the elderly people is massaged symmetrically through the back plate 23.

When encountering uneven road surfaces such as steps, the shock absorber 52 can be instantly compressed under the double action of the wheelchair and a user, the hub in the shock absorption wheel 18 can also move downwards temporarily, so that the impact force received when the wheelchair falls to the ground can be reduced, the bumpy feeling when the wheelchair falls to the steps can be reduced, after the wheelchair passes through an obstacle, the downwards-moved hub can be restored to the central position of the shock absorption wheel 18 in a very short time, and the shock absorption wheel 18 can absorb the impact force when the wheelchair falls to the ground as advancing energy, so that the technology has the advantages of energy conservation, low maintenance cost and safer use. In addition, the dual cushioning effect of the damper 52 and the tire may result in better comfort.
