Description

Vehicle for helping troops

Technical field

Utility model is about vehicle for helping troops, especially seat is left, middle part, face both sides, bottom right, each welds a seat axle sleeve, do again two seat supports, the highly moderate end seat axle sleeve of burn-oning respectively, burn-on the respectively card article 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 blocks respectively, two seat supports is placed on respectively the vehicle frame both sides, on the diaxon bearing of back axle, two seat supports are wanted same vehicle frame, the car rear axle is vertical, bearing block, vehicle frame, seat support is fixing dead with 4 screws, uses the seat axle two axle sleeves of seat, two axle sleeves of seat support are together in series.

General stair angle at 45 °, the place ahead is equipped with a hydraulic control pump and is connected with vehicle frame in the seat bottom surface, can control that seat is forward and backward respectively to be turned till 45 °, its controller is contained on the handlebar, hydraulic controller is controlled at level to seat at ordinary times, rear axle is by the motor drives with accumulator, and motor controller also is contained in (two controllers are contained in respectively the handlebar two ends) on the handlebar.

Background technology

For particularly not having people handicapped in the building of elevator in living in building, the problem of upward going downstairs has become the major obstacle of their go off dailys, and for this crowd's upper problem downstairs, I have designed this car for going upstairs and downstairs.

The utility model content

If this car owner seat can be by each can rotate 45° angle before and after the hydraulic control pump, people's steering controller makes seat turn forward 45 ° in the time of upstairs, the people is still perpendicular to the ground like this, in the time of downstairs, the people can swing back 45 °, the people also can keep vertical with ground, the center is balance when going downstairs on this car, and by the motor drives with accumulator, speed is moderate in the time of upstairs, in the time of downstairs, because stair are 45° angle, car and people are added together very heavy, and lower punch power is very large, so the brake on the rear axle must be clever, fixing dead with rear axle because of one of rear wheel, another can freely rotate on rear axle, for safer, to establish a lock at the trailing wheel that rotates and connect together with the rear braking device and must play the effect of brake, be critical in the time of downstairs and press brake with regard to energy warrantor's safety.Brake also can equally with the brake of bicycle or motorcycle be located on the handlebar.

Because of the stairway step height generally about 17cm, the trailing wheel radius should be greater than shoulder height, rear wheel diameter should be 35～40cm for well, be better up/down steps, I adopt and am combined as a front-wheel by three equal steamboats, be three horn rings, each little wheel diameter should be about 20cm, because the car rear axle is because there being bearing block, vehicle frame is a little more than the trailing wheel radius, so front axle is slightly larger than the trailing wheel radius for well apart from the distance on ground, omit lower front in the seat bottom and establish a hydraulic control pump, make at ordinary times seat remain on level, the people can go to play everywhere or work, the speed of a motor vehicle is unsuitable fast, for alleviating upper vibrations downstairs, seat bottom can be provided with spring cushion, the wheel nausea is less, also be provided with pedal so that upper more comfortable downstairs, also can help operation by the nursing staff, the following people of the most suitable 175cm of this car uses, this car also can be made the tank track formula, available aluminium alloy plate (light and hard), one deck rubber can be installed to alleviate vibrations in the aluminium alloy plate bottom, length should be about 70cm before and after the whole crawler belt, because general corridor turning area is at a square meter, so car should be slightly less than a square meter when design, vehicle for helping troops, comprise vehicle frame, a back axle (has fixedly flywheel on the back axle, fixing two bearing blocks of brake), two rear wheels, a seat, two seat supports, a seat axle, 4 seat axle sleeves, a front truck fork, a front vehicle fork sub-set, a handlebar, a front vehicle wheel that is formed by three wheels, a rear wheel brake, an electric machine controller, a hydraulic control pump, a motor, one group storage battery, it is characterized in that seat is by two axle sleeves of two seat support tops weldering and two axle sleeves of middle part, both sides, seat bottom weldering, these four axle sleeves are cascaded by a seat axle and are supporting, it is characterized in that seat can be by rotating 45 ° before and after the hydraulic control pump control, it is middle slightly forward that the control pump upper end is connected in rotatable seat (3) bottom, the other end is connected on the vehicle frame (2), it is characterized in that the easy up/down steps of the front-wheel that is formed by three trundles, can alleviate vibrations, the distance that three-wheel forms front vehicle wheel centre-to-centre spacing ground equals or is slightly larger than the trailing wheel radius for well.
