Abstract

The invention discloses a vehicle for the old, the weak, the sick and the disabled to go upstairs and downstairs, which is easy to manufacture, is convenient for the old, the weak, the sick and the disabled to go upstairs and downstairs, has low cost and wide application scope, and is suitable for mass production. The notices are as follows: when the vehicle is used for going upstairs and downstairs, a brake is handy; the direction is mastered through handle bars; two rear wheels simultaneously go up and down steps; and the vehicle is operated by the help of another person, and the old, the weak, the sick and the disabled can use the vehicle after mastering skilled operation.

Description

The old,weak,sick and disabled's car for going upstairs and downstairs

Technical field

The invention relates to old, a little less than, sick, on residual, car downstairs, especially a seat left side, middle part, face both sides, bottom right, each welds a seat axle sleeve, do two seat supports again, the highly moderate end seat axle sleeve of burn-oning respectively, burn-on the respectively rectangular base plate of fixation of the other end, on two screw holes are arranged, pitch-row is identical with two holes on the vehicle frame with two bearing seats respectively, two seat supports are placed on the vehicle frame both sides respectively, and on the diaxon bearing of back axle, two seat supports are wanted same vehicle frame, the car rear axle is vertical, bearing seat, vehicle frame, seat support is fixing dead with 4 screws.With the seat axle two axle sleeves of seat, two axle sleeves of seat support are together in series, general stair angle at 45, each is welded into the plate washer of 45 respectively with a block plate on each axle sleeve both sides of seat, when seat changes 45, plate washer stops operating with regard to running into seat support, back axle is by the motor drives that has storage battery, and motor controller is by on handlebar.

Background technology

Much old, weak, sick, the residual personnel that upstairs live at present, movable difficulty can not go up downstairs, and is with social isolation, very painful.

Summary of the invention

If this car owner seat can freely rotate front and back, because seat bottom is provided with former and later two 45 plate washers, so can only rotate 45 ° before and after the seat, in the time of upstairs, the people turns forward 45 °, the people is still perpendicular to the ground like this, in the time of downstairs, the people can be to 45 ° of layback, and the people also can keep vertical with ground, on this car, center of gravity is a balance in the time of downstairs, by the motor drives of band storage battery, speed is moderate in the time of upstairs, in the time of downstairs, because stair 45, car and people add very heavy together, and lower punch power is very big, so the brake on the back axle must be clever, because of one of rear wheel is fixed dead with rear axle, another can freely rotate on rear axle, for safer, establish a lock on rotating trailing wheel, be associated in the back brake, be critical in the time of downstairs and press just energy bondsman's safety of brake.

Because of stair platform Bands, highly generally about 17mm, the trailing wheel radius should be greater than platform Bands height, and back wheel diameter should be 35～40mm for well.Be better upper and lower Bands, I adopt and am combined as a front-wheel by three equal steamboats, am three horn rings, and each little wheel diameter should be left and right at 20mm.Because the car rear axle is because of there being bearing seat, vehicle frame is a little more than the trailing wheel radius, so the ground-surface distance of front wheel spindle distance is slightly larger than the trailing wheel radius for well.The bar of one mobilizable fixed seat horizontal force is established in the seat front lower place, can make seat maintenance level strengthen attitude at ordinary times, the people can go to play everywhere or work, the speed of a motor vehicle is unsuitable fast, for alleviating the vibrations in upper and lower building, seat bottom can be provided with the spring cushion, and the wheel nausea is less, also be provided with stretcher, upper and lower building is just chatted and has been obeyed.The paramedic also can help operation.The following human of the most suitable 175mm of this car is for well, and this car also can be made bullet gram crawler-mounted, available aluminium alloy plate, and light one deck rubber can be inlayed in the aluminium alloy plate bottom and hard, alleviates vibrations, and whole crawler belt front and back length should be left and right at 70mm.Because the area at general corridor turning is at a square meter, car should be slightly less than a square meter when design.This car Success in Experiment.

The specific embodiment

Back axle 4 is loaded onto two rear wheels 10 respectively, vehicle frame 2 is placed on two bearing seats of rear axle 4, bearing seat is not drawn on drawing, two seat supports 6 are contained in vehicle frame 2 both sides respectively, on the corresponding position with two bearing seats of axletree 4, respectively bearing seat, vehicle frame 2, seat support 6 are fixed extremely with 4 screws, 4 seat axle sleeves on seat 3 and the seat support 6 are cascaded with seat axle 7.Seat 3 is rotated before and after can be free to well.Front vehicle fork cover 14 is welded in the position that vehicle frame 2 is upturned previously, the necessary vertical ground in car fork cover 14 front, rear, left and right is also middle at vehicle frame 2, load onto front truck fork 8, load onto front vehicle wheel 5 in front truck fork 8 lower ends, refill handlebar 9, on the car rear axle, install brake 15, trailing wheel brake 13 is associated in together with brake 15, brake 15 and brake 13 must be clever, really play the effect of brake.Electrical motor 11 storage batterys 12 are contained on the vehicle frame 2, and motor controller is contained on the handlebar 9, and motor controller is not drawn on drawing, and the seat fixed link 16 of fixed seat 3 is contained on the vehicle frame 2 of seat front lower place, and this car assembling finishes.
