Bicycle is that occur in the recent period a kind of utilizes foot pedal to provide the roller board of onward impulse for car.The features such as Kickboard Scooter is simple to operate with it, modelling fashion, entertainment body-building are integrated sweep the country, and current Kickboard Scooter market is broadly divided into following several form by type of drive: step sliding board vehicles, manpower drive Kickboard Scooter, Segway Human Transporter etc.Nowadays foot pedal type Kickboard Scooter is seen everywhere in streets and lanes, and step sliding board vehicles is easily fallen down, very large to the infringement of knee endoprosthesis ankle, does not look at by the parent of children and the head of a family; And the fast safety of electric return board vehicle speed is not high, recreational, interesting poor, lack the function of taking exercises, Battery disposal exists pollutes, and maneuverability also affects larger by battery, be used to riding instead of walk instead of entertainment for children of short distance more; Manpower drives Kickboard Scooter all to adopt the stand-type control structure of single pedal, efficiency, handling and the recreational requirement that all can not meet customer.
Utility model content
The technical problems to be solved in the utility model is to provide one and is convenient for carrying, and drinking-water is convenient, double end two mouthfuls of multiple-purpose cups of good heat insulating.
For solving the problem, the technical solution adopted in the utility model comprises nose wheel steering, body frame structure for automotive, rear wheel drive system, it is characterized in that: described rear wheel drive system comprises primary transmission system and secondary driving system, described primary transmission system comprises one-level chain, one-level chain is driven thus flywheel driven rotation by front running board or back step, described one-level chain end is connected with retracing spring, described secondary driving system comprises secondary chain, and the hinge wheel coaxial with flywheel is rotated by secondary chain-driving minor sprocket.
Described two pedal stand two controls children's Bicycle, it is characterized in that: also comprise armchair structure, and described armchair structure comprises telescopic folding type seat, and adopts slide rail mode roll adjustment.
Described two pedal stand two controls children's Bicycle, it is characterized in that: described steering swivel system of taking turns comprises front wheel spindle, and described front wheel spindle front end arranges cardan wheel, is provided with shock-proof spring between described front wheel spindle and body frame structure for automotive.
Described two pedal stand two controls children's Bicycle, it is characterized in that: described body frame structure for automotive comprises the handle, main body body support and the trailing wheel fixed support that are fixedly connected with.
Two pedal stand two of the present utility model controls children's Bicycle, it by nose wheel steering, body frame structure for automotive, rear wheel drive system and armchair structure four part form.Nose wheel steering adopts cardan wheel and is furnished with shock-proof spring; Body frame structure for automotive comprises handrail, main body body support and trailing wheel fixed support etc., and chassis adopts Three-wheel type design, and handle three sections is flexible collapsible; Rear wheel drive system is secondary chain type; Seat Telescopic folding.Two pedal before and after Bicycle adopts, stand or sitting all can control mode, considerably increase the recreational and efficiency of the manipulation of Bicycle.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1, two pedal stand two of the present utility model controls children's Bicycle, comprise nose wheel steering, body frame structure for automotive, rear wheel drive system, described rear wheel drive system comprises primary transmission system and secondary driving system, described primary transmission system comprises one-level chain 6, one-level chain 6 is driven thus flywheel driven 9 rotates by front running board 5 or back step 7, described one-level chain 6 end is connected with retracing spring 15, described secondary driving system comprises secondary chain 12, the hinge wheel 10 coaxial with flywheel 9 drives minor sprocket 13 to rotate by secondary chain 12, to reach the object increasing transmitting ratio.
For optimizing such scheme further, also comprise armchair structure, described armchair structure comprises telescopic folding type seat 8, and adopts slide rail mode roll adjustment.Telescopic folding type seat 8 realizes up and down and front and back roll adjustment function, adopts slide rail mode roll adjustment hand switch to fix seat position.Seat support is folding and fixing by Triangle Principle.Article two, sliding rail distinguishes upper-lower height and the longitudinal separation of adjusting seat.
Described nose wheel steering comprises front wheel spindle 1, and described front wheel spindle 1 front end arranges cardan wheel 16, is provided with shock-proof spring 2 between described front wheel spindle 1 and body frame structure for automotive.To increase the stationarity that car travels.
Described body frame structure for automotive comprises the handle 3, main body body support 4 and the trailing wheel fixed support 11 that are fixedly connected with.A simple space structure, for ensureing that vehicle body overall weight and weight capacity adopt the aluminum alloy of lightweight.Chassis adopts three-wheel design to increase stationarity and the safety of car.Handle 3 is three sections of flexible folding structures, comparing general two joints, adjustable to increase to three joints adjustable, by regulating the height of handle and the front and back of seat and upper and lower distance, manipulate under the state allowing the people of the different height bodily form all be in the most comfortable, and folding square Portable belt.
The principle of work of Bicycle is shown in Fig. 2.The hand steered handle of treadmill person, pin steps on front running board 5 or former and later two pedals of back step 7(share pedal shaft 2a, tramples any one and all can give active force), drive one-level chain 6 to move on certain track.One-level chain one end is fixed, one end is connected with retracing spring 15, foot pedals makes the one-level chain movement be meshed with flywheel, thus flywheel driven 9 rotates, flywheel is coaxial with hinge wheel 10, and flywheel drives hinge wheel to rotate, minor sprocket 13 is driven to rotate by secondary chain 12 again, minor sprocket and little Lian wheel shaft 13a fix, thus drive the trailing wheel rotating in same direction being fixed on little Lian wheel shaft, and trailing wheel promotes Bicycle as active force and moves ahead.Unclamping pedal travel retracing spring pulls chain to reset, and repetitive operation can realize stepping on reforwarding and move.Establish overriding clutch in flywheel, automatically can move ahead under Gravitative Loads on acclive ground.
For vertical manipulation, concrete control mode is: fixing front running board, right crus of diaphragm tramples back step, pedal rotates around fixed pedestal axle 2a, one-level chain moves around driving chain wheel 3a and front bar sprocket wheel 13a, flywheel driven and flywheel shaft 6a rotate, and simultaneously one-level chain-driving fork 12a moves right retracing spring 15 and stretches, and completes primary transmission; Hinge wheel co-axially fixed with flywheel, rotate with cireular frequency at flywheel turns simultaneously, rotated by secondary chain-driving minor sprocket and the chainlet wheel shaft that is fixed together with it, drive the trailing wheel rotating in same direction be fixed on chainlet wheel shaft simultaneously, thus rear wheel movement, car is travelled forward, completes secondary transmission.Unclamp back step, pull chain slowly to get back to original position by spring force in car motion simultaneously.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., be all included within protection domain of the present utility model.
