Specific embodiment

As shown in Fig. 1-5, this robot assistant wheel-chair provided in this embodiment, it includes vehicle body 1, elevating mechanism 2 With seat 3.

Vehicle body 1 includes vehicle frame 11 and the front-wheel 12, rear-wheel 13 and the sidesway wheel assembly 14 that are set under vehicle frame；Front-wheel 12 is ten thousand To wheel；Rear-wheel 13 is directional wheel；Sidesway wheel assembly 14 includes lifter plate 141 and a pair of of the sidesway wheel for being installed on lifter plate bottom 142, sidesway wheel is directional wheel and the direction of motion is vertical with rear wheel movement direction.Electric pushrod and guide sleeve are additionally provided on vehicle frame 15, lifter plate 141 is externally provided with lift rail 143, is connected between lifter plate and vehicle frame by electric pushrod when assembly, and by guide sleeve The stationarity to guarantee lifting is assembled with lift rail, prevents from rolling.Sidesway wheel assembly 14 is liftoff when normal use, by preceding Wheel, rear-wheel control the direction of motion, so that sidesway wheel assembly downlink is jacked up rear-wheel, this side by electric pushrod work when needing sidesway It moves wheel and controls the direction of motion with front-wheel, can easily realize the lateral movement of wheel-chair.

Elevating mechanism 2 includes four electric pushrods for being set to vehicle frame quadrangle, and both sides installation site is respectively from wheelchair or so There is a distance of 120mm in side, and after wheelchair rises, handrail unlock is pressed backward, can be with vehicle body same plane, wheelchair body bottom section 120mm under into bed, the plane that support people lies can also reach 120mm on bed surface, and people closely exerts oneself at station beside wheelchair People can be assisted to go to bed.The bottom of seat 3 is connected with the top of electric pushrod.In order to go up and down seat steadily, the one of seat Side is equipped with a pair of sliding rail 4 along short transverse arrangement, Vehicular side body for being equipped with a pair of of guide holder 5 at sled position, sliding rail Lower part extends in guide holder 5.

Seat 3 includes backrest 31, pedestal 32 and toeguard 33, and backrest is articulated with one end of pedestal, toeguard with its bottom It is articulated with the other end of pedestal with its top, a pair is equipped between the bottom of backrest and the top of toeguard about base width side To the link mechanism 34 of arrangement and the telescopic rod 35 of drive connecting rod mechanism movement.

Link mechanism 34 includes the first backrest connecting lever 341, the second backrest connecting lever 342, connecting rod 343 and toeguard connecting lever 344； First backrest connecting lever is postponed arrangement along backrest length direction；Second backrest connecting lever is in tilted layout, and lower part passes through connecting lever axis 345 and the One backrest connecting lever is connected, and top is towards toeguard；Toeguard connecting lever is in tilted layout, and top is connected to the top of toeguard, lower part Towards backrest；One end of connecting rod is connected with the lower part of toeguard connecting lever, and the other end is connected with the first backrest connecting lever；Telescopic rod 35 with Its body of rod is connected to the lower part of pedestal, is connected with its piston head with the second the high-end of backrest connecting lever.

In use, the piston rod for controlling telescopic rod stretches out the present embodiment, and piston rod pushes the first backrest to turn at this time Arm moves backward, rises backrest slowly, until backrest is perpendicular to seating plane, it is 90 ° of maximum angle, while connecting rod synchronizes backward Toeguard is pulled, toeguard moves downwards, and when backrest reaches 90 °, toeguard and pedestal are also in 90 °；In turn, telescopic rod is shunk When, pull the first backrest connecting lever, backrest slowly puts down, until and pedestal in same plane, which is known as 0 °, at the same backrest with Connecting rod, which synchronizes, between foot backplate travels forward, and makes backrest and pedestal and toeguard at a plane.So that backrest and toeguard Can in 0 ° -90 ° electrodeless adjustment, user can lie low on wheelchair or angle arbitrarily adjusts.

Hospitals at Present nursing bed (hospital bed) or home-use nursing bed, operating table, CT scan platform, etc. general height be 600mm~650mm high, bed base space are 450mm~500mm, and it is suitable that nursing wheelchair height, which is 400mm~450mm, Highly, to enable patient easily to reach above-mentioned height, seat and vehicle body are seperated connection, seat can vertical up-or-down movement, from a left side Four synchronous electric telescopic rods are installed apart from surrounding in the right, thrust 400Kg, raise seat and reach and need highly, and mating biography Sensor measurement is suitable highly to control adjustment.Simultaneously because the wheel being mounted laterally can be let droop by electric pushrod along sliding rail It directly pushes down, rear-wheel is lifted off ground, stress and preceding universal wheel four-wheel are taken turns coplanar in rear side position, and nursing chair can be vertical close to mesh Mark (bed etc.), chair lower part can enter 100~120mm of bed bottom, and chair top-backrest-toeguard enter 100 above bed~ 120mm, patient can lean to one side to go to bed, and the serious patient that cannot take care of oneself can easily be moved patient beside wheelchair by a caregiver Bed.It realizes general patient to take care of oneself, cannot take care of oneself serious patient, also only need a caregiver that can easily look after.

Can also connect on wheel-chair plus with communication module (4G smart card) with touch screen simultaneously, can chat on line with Watch entertainment, while convertible remote control can also be understood and grasped at any time by mobile phone in you of working work, be closed The heart, filial devotion allow patient full of warm love, solve the boring worry with household of patient.Two dimensional code, Ke Yishi can be also added simultaneously When lease.
