Abstract
The utility model relates to a multi-functional stair climbing vehicle. Friction movement is generated by a stair climbing wheel and the ground surface or the stair edges of stairs. The stair climbing wheel is prompted to move forwards smoothly. The utility model alters that the previous vehicle can not run along stairs. The wheel of the stair climbing vehicle is led to cross the stairs, which avoids that vertical surfaces of the stairs hinders the wheel. A moving adhesive tape is used to form a rotation plane which is laid among the stair edges. (A plane can be determined if two parallel lines among the stair edges.) The stair climbing vehicle can smoothly move on the stair edges. The utility model is convenient for people to go upstairs and go downstairs to pull and convey articles or to carry babies. The multi-functional stair climbing vehicle can also run. Goods can be loaded and unloaded on the vehicle. People's inconvenience of carrying the articles to go upstairs and go downstairs is relieved. Work efficiency is improved.
Description
The utility model is about the haul article, carry the baby, travelling is gone out on the running tool, particularly stairway step can conveying objects up and down the time multi-functional Stairs climbing vehicle.
Cars such as waggon, perambulator, suitcase are made up of two wheels or four wheels, produce friction with ground and order about the car ahead running.The wheel of its car all is circular, is made up of the axis of rolling, bearing, wheel rim, when wheel and ground generation friction, forms frictional transmission, and wheel rim rotates with antifriction-bearing box, is the center with the axle, moves in a circle along straight line, so just drives car and moves ahead.But its wheel has such problem, when meeting stairway step, because interlacing, the height between the step but can not move up and down with step, wheel will produce friction drag and just can impel wheel to move, when wheel is done operation on a vertical plane, wheel and vertical plane surface can not produce friction drag, and wheel just can not produce motion like this.The formed vertical surface of height between the step has just in time stoped the motion of wheel in fact.Therefore waggon, perambulator, suitcase move when meeting stair and step and are hindered, and people have only or carry or lifting car stair activity step and solve the inconvenience of hauling article for this reason.
The purpose of this utility model is the car that a kind of improved waggon, perambulator, suitcase will be provided, and it can be integrated waggon, perambulator, suitcase effectively, makes its wheel reach the instrument that can both directly move up and down at stairway step on the ground.
The purpose of this utility model is to reach by following measure: be skeleton with the waggon, by the movable suitcase of dress energy, can take off suitcase when the haul article on its supporting plate, being used as whilst on tour can be by last suitcase.Simultaneously in the both sides of supporting plate respectively by adorning a portable bar, an end is by on supporting plate, the then same tetragonal framework of the other end connects, tetragonal framework is on one side with the pull bar, portable bar forms baby's frame with tank bracket like this, as placing baby's use.When pull bar moved up and down, baby's frame can move and mobile with pull bar, and this is to exercise because of car to change on ground and between stairway step.Its wheel is as a kind of power wheel, form two pairs of scroll-up/down wheels in the both sides of car, connect by a motion adhesive tape between every pair of scroll-up/down wheel, its effect is across stairway step, because of the rank of step along by as two parallel liness, article two, parallel lines is determined a plane, and the low-order and high-order edge of stair has been avoided on the plane that the motion adhesive tape forms, and drives by scroll wheel it can smoothly be rotated on step.Is made up of the sliding wheel and the frame plate that slides fixedly between the inboard of motion adhesive tape and scroll-up/down wheel, slip is the fixing sliding wheel of frame plate fixedly, and sliding wheel supporting movement adhesive tape makes it be unlikely to cave in.Scroll wheel, motion adhesive tape, sliding wheel and the fixedly frame plate composition ascending stair wheel integral body of sliding, the ascending stair wheel is connected to the bottom of supporting plate mutually by pipe link.When Stairs climbing vehicle moved on ground or on stairway step, the motion adhesive tape of ascending stair wheel and ground or stairway step produced frictional rotation and drive scroll wheel and sliding wheel, and the transmission of scroll wheel and sliding wheel impels the motion adhesive tape to rotate, and formed smoothly and moved.
The utility model is based on waggon, and the usefulness of perambulator, suitcase is integrated, and circular wheel is changed over the wheel of adhesive tape type, no matter is the haul article, still carries the baby and can move up and down smoothly on step when meeting stairway step.Because circular wheel is subjected to the obstruction of step height on step, can not do straight-line motion along step.The wheel of adhesive tape type difference, adhesive tape can be across the rank of step along last, form a kind of rotational plane (two parallel lines is determined a plane) and avoided the obstruction of step height, the running of the wheel of adhesive tape type can be done the effect of running body building and automobile loading and unloading article in addition, so the level and smooth rotation energy of adhesive tape is realized the requirement of ascending stair and motion.
The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the constructional drawing according to the multi-functional Stairs climbing vehicle that the utility model proposes, and Fig. 2 is the cutaway view according to the multi-functional Stairs climbing vehicle that the utility model proposes.
Describe the structure and the running condition of the concrete Stairs climbing vehicle that the utility model proposes in detail below in conjunction with Fig. 1 and Fig. 2.
This Stairs climbing vehicle comprises main body rack plate (1), upper end at supporting plate connects pull bar (2), the pull bar top is angular adjustment handle (3), the supporting plate lower end baffle plate frame (4) that joins, the quadrilateral frame that the portable bar of supporting plate both sides and pull bar connect and compose is baby's frame (5), direct coupled with the supporting plate bottom is two pairs of scroll wheels (6), its inside is ordered about by antifriction-bearing box (7), every pair of scroll wheel is connected a motion adhesive tape (8), between every pair of scroll wheel and the supporting movement adhesive tape be sliding wheel (9) and slide shaft (10), the axis of rolling of fastening scroll wheel (11) is directly connected in supporting plate and fixedly frame plate (12) and fixed connecting rod (13) interconnect with the slip of fixing sliding wheel.
Suitcase (not drawing among the figure) on the supporting plate (1) of Stairs climbing vehicle forms one with baby (5), the baby can be carried and article can be consigned again, when car is met stairway step, pull pull bar (2) and drive motion adhesive tape (8) translation rotation scroll wheel (6) formation drive manner, sliding wheel (9) supporting movement adhesive tape (8) also can slide its unlikely depression on the edge, rank.Because of the gradient that stairway step and ground form, Stairs climbing vehicle and human body are adapted and adopt angular adjustment handle (3) to regulate.Single motion adhesive tape (8) is with scroll wheel (6) and the mutual transmission of sliding wheel (9) can make the people do running in place body building and automobile loading and unloading weight is effective equally.
