Detailed Description

The invention is further described below with reference to the accompanying drawings.

As shown in figures 1-4, a household multifunctional walking chair for old people comprises a chassis 1, a driving wheel mechanism 2, a supporting and adjusting mechanism 3, a seat 4 and an annular armrest 5.

Be equipped with seat 4 on the

chassis

1, 1 top on chassis is equipped with supports adjustment mechanism 3, it is equipped with annular handrail 5 to support adjustment mechanism 3 top, can adjust annular handrail 5's height through supporting

adjustment mechanism

3, 1 bottom on chassis is equipped with driving wheel mechanism 2, can carry out the bulk movement to chassis 1 through driving wheel mechanism 2.

The supporting and adjusting mechanism 3 comprises a group of electric push rods 301, and the group of electric push rods 301 are symmetrically arranged on the top of the chassis 1.

The chair 4 comprises a chair seat 401 and a turnover chair seat 402, wherein the turnover chair seat 402 is hinged on the chair seat 401, and the turnover chair seat can rotate 90 degrees.

The chassis 1 adopts a circular arc chassis 101, and openings are formed at two ends of the circular arc chassis 101 and used for barrier-free access.

The chassis 1 is provided with a control device (not shown in the figure), a box body of the control device can be directly fixed on the chassis 1, a single chip microcomputer and a control circuit are arranged in the control device to realize the control of the driving wheel mechanism 2, and the annular handrail 5 is provided with a remote control handle for controlling the driving wheel mechanism 2 and the supporting and adjusting mechanism 3 to work.

The chassis 1 is also provided with an infrared gait tracking device 6 which automatically tracks the gait of the old when the old walks and reacts the gait to the motor, so that the motor drives the wheat wheel to slowly rotate, thereby achieving the gait tracking effect.

The driving wheel mechanism 2 comprises four independent driving devices which are symmetrically arranged, each independent driving device comprises a motor 201 and a Mecanum wheel 202, and the motors 201 are in transmission connection with the Mecanum wheels 202. The omnibearing motion equipment based on the Mecanum wheel technology can realize the motion modes of advancing, transverse moving, oblique moving, rotating, combining and the like. The chassis is very suitable for the working environment with limited space and narrow passage in a small living room, can simplify a steering mechanism and a transmission system, has a simple structure, reduces the weight, and has obvious effects on improving the working efficiency and increasing the utilization occasions of the scooter. The 4 wheat wheels independently run through 4 sets of motors, and realize synchronous/differential control through a main single chip microcomputer system, so as to realize linear/steering motion. Therefore, the device uses the Mecanum wheels, can realize all-directional movement, and reduces the resistance generated by direction limitation. Meanwhile, the infrared gait tracking device 6 is installed on the device chassis, the walking state of the old is automatically identified, namely the old automatically follows the old through the whole device in the walking process, so that the function of saving the old is achieved, meanwhile, a protection measure is provided for the old in the walking process, and the safety of the old who is at home alone is guaranteed.

The annular handrail 5 comprises an arc-shaped fixed handrail 501 and an arc-shaped sliding handrail 502, the arc-shaped sliding handrail 502 is in sliding fit with the two ends of the arc-shaped fixed handrail 501, a clamping groove is formed in the end portion of one arc-shaped sliding handrail 502, and a buckle matched with the clamping groove is formed in the end portion of the other arc-shaped sliding handrail 502. Annular handrail 5 can realize preventing that the old person from falling down, for the old person acts as the handrail when driving/walking, and for the old person provides certain helping hand when getting up/standing up like the lavatory to for the old person provides the omnidirectional when like the lavatory and prevents falling the protection. The arc-shaped fixed handrail 501 of the annular handrail is a 240-degree annular circle, and two sides of the fixed handrail are respectively provided with a slide rail groove with a central angle of 60 degrees for installing the arc-shaped sliding handrail 502 with two sides of 60 degrees. The arc-shaped sliding handrail 502 slides in the sliding groove, and the whole arc-shaped sliding handrail just synthesizes a whole circle when sliding out of the maximum displacement at two sides; the buckle and the clamping groove are matched to enable the clamping to be carried out at the maximum displacement position, and the whole circle plays a role in protecting the old in an omnidirectional mode.

Example (b):

1) when the electric chair is used: the old person gets into the car of riding instead of walk through annular handrail breach department to fold arc slip handrail through the buckle. After the seat of the walk-substituting chair is seated, the Mecanum wheels of the chassis can be controlled by the remote control handles on the armrests, so that the vehicle can run. And simultaneously, the chassis can be controlled by an APP installed on the mobile phone. Convenient, fast and reliable operation is realized.

2) When the walking frame is used as a walking frame: the old man stands upright inside the automobile body, and the seat turns up 90 at this moment, has enlarged automobile body inner space. The old man goes up and down through 4 electric putter of lift button adjustment, makes the handrail adjustment when standing to be the most suitable old man and holds the state, and the old man holds the handrail and slowly walks, and at this moment helps the frame to trail old man's gait condition through infrared gait tracking device to react it to the motor, make the motor drive wheat wheel slow rotation, reach the gait and trail the effect, and can prevent that the old man from falling down.

3) When serving as the toilet assisting power: the old drives or holds the multifunctional chair close to the toilet seat, and extends the sliding rail right above the rear edge of the toilet seat, so that the old is protected by the armrests. The old man can be according to the action such as the handrail is turned round of holding up by oneself the condition. After finishing like the lavatory, the old man can press the flexible button of electric putter in annular handrail both sides and adjust the push rod height, adjusts to the adaptation height after the old man grabs the handrail, presses the button that rises simultaneously, and the push rod slowly rises, gives the old man a power of getting up, helps the old man to get up.
