The utility model content
The utility model provides a kind of reasonable in design, and is with low cost, and control operation is convenient, it is little to take volume, can realize the wheeled portable car that short distance is ridden instead of walk, and it adopts manpower to drive, safety and environmental protection can be carried, better realization with being used of existing urban transportation tool.
The technical solution adopted in the utility model is as follows:
A kind of wheeled portable car, comprise a vehicle frame, it is characterized in that by a wheel shaft one roller being set on the described vehicle frame, the vehicle frame lower end of described roller both sides arranges pedal, a miniature gears is established on described roller right side, described miniature gears is connected with roller with ratchet by flower-drum, described miniature gears and ratchet combination, miniature gears and ratchet, described roller coaxial rotation.The front end of described vehicle frame connects a steady wheel, described steady wheel is connected with vehicle frame with pivot by a wheel carrier, the diameter of described roller is greater than the diameter of steady wheel, the right side of described vehicle frame connects a rocking bar, described rocking bar is connected with vehicle frame by a pivot, described rocking bar lower end connects a connecting rod, described connecting rod is connected with vehicle frame by a bent axle, and the inboard of described bent axle connects a big gear wheel, described big gear wheel and described pinion, by rocking bar drivening rod bent axle, crank motion is converted to circular movement, drives large pinion rotation, thereby drive the roller motion, it is characterized in that utilizing lever principle, hand rocking bar drives the lower end connecting bar and crankshaft and rotates, and rotates thereby drive described big gear wheel, by big or small meshed transmission gear, drive described roller motion.
Concretely, described vehicle frame comprises the housing that is symmetricly set on the roller left and right sides, sets up wheel shaft between the housing of described both sides, and described roller is located at the centre of vehicle frame by axle stand.
The bottom of described vehicle frame outwards arranges the pedal of placing for foot, and described pedal is symmetricly set on the roller both sides of vehicle frame bottom, is reduced volume, and described pedal is designed to foldable.
The housing of the left and right sides of described composition vehicle frame is combined into one on the top of roller, and the top of described vehicle frame arranges one can supply portable handle.
The front end bottom of described vehicle frame arranges a wheel carrier, and described steady wheel is connected with wheel carrier by the pivot that arranges on the wheel carrier.
The diameter of described roller is 20～40cm, and the diameter of described steady wheel is 8-15cm.
Described roller and steady wheel arrange in same plane, the wheel shaft of described installation roller and the pivot that steady wheel is installed, connect that connecting rod is connected bent axle with big gear wheel, the pivot that connects rocking bar and vehicle frame be arranged in parallel.
Described miniature gears and described roller are connected with flower-drum on the roller by ratchet, and miniature gears and ratchet combination are rotated synchronously with roller, and miniature gears, ratchet, roller are coaxial.
Described rocking bar is scalable, the length when adjusting different conditions.
This wheeled portable car does not have vehicle seat and handlebar, and the user can by pin being placed on the pedal on the vehicle frame, realize the load-bearing of this Portable vehicle.Roller and steady wheel make this Portable vehicle realize displacement simultaneously as road wheel and ground touch scrolling, and roller is bull wheel, mainly advances and load-bearing by it, and steady wheel is steamboat, and it is mainly used in stablizing this Portable vehicle.Steady wheel can rotate around itself and vehicle frame connecting portion with wheel carrier, when turning to, keep the stable of this Portable vehicle, the user is placed on two pin on the pedal of roller both sides, with the hand bar that shakes, drive the connecting bar and crankshaft of rocking bar lower end, move ahead by big or small meshed transmission gear driving rolls, the miniature gears place on roller right side is provided with ratchet, realized the function of similar spider handle for bicycle, realized advancing easily flexibly.
But user's nationality is realized turning to of this Portable vehicle by shank to the application of force of vehicle frame.Steady wheel forms two fulcrums with roller in traveling process, the stability of advancing and the stability that turns to are provided.The top of vehicle frame can arrange handle, and pedal is collapsible, also capable of regulating of rocking bar length, is easy to carry.
The beneficial effects of the utility model are, the reasonable in design of this wheeled portable car is novel, can realize that control operation is convenient, take the little advantage of volume, with low cost, adopt manpower as action power, safety, fashion, health, environmental protection can be carried by simply folding and operation.In addition, the utility model has changed the foot-operated type of drive that people commonly use, and adopts driven by shaking, for people provide a kind of new selection, when being used for body-building, riding instead of walk also better realization with being used of existing urban transportation tool.
