Description

Pedal scooter

Technical field

The utility model relates to a kind of Kickboard Scooter, particularly a kind of foot-driven Kickboard Scooter.

Background technology

Kickboard Scooter since have light and handy flexibly, good, the recreational characteristics such as strong of maneuvering performance, all over the world fashionable in recent years.Present Kickboard Scooter generally needs the single pin of user to stand on the Kickboard Scooter, and an other pedal is stepped on ground and produced thrust, promotes Kickboard Scooter and user and advances; The user also need control direction and guarantee the Kickboard Scooter balance when promotion is advanced, the coordination ability requires high, influences safe reliability, can bring certain difficulty to the beginner like this; In order to make Kickboard Scooter continue to advance, the user needs constantly to step on ground with pedal, and the movement range size directly influences the speed of advance of Kickboard Scooter, and prolonged exercise also will consume a large amount of physical efficiencys, can only be used for the body building equipment, can not be as user's walking-replacing tool.For this reason, many manufacturers and knowledgeable people research and develop at the problems referred to above, but do not have the Kickboard Scooter that can body-building can ride instead of walk again to emerge on market so far as yet.

Summary of the invention

For overcoming the above-mentioned disadvantage that existing Kickboard Scooter exists, the purpose of this utility model provide a kind of simple and reasonable, easy for operation, speed fast, the Kickboard Scooter that can body-building can ride instead of walk again.

The technical scheme that its technical matters that solves the utility model adopts, it comprises handle, standpipe, vehicle frame, front and back wheel, brake gear, described vehicle frame is provided with foot drive device, this device comprises step; rocking arm; torsion spring; one-level sprocket wheel; main shaft; minor sprocket; secondary sprocket wheel; countershaft; the major-minor axle is arranged on the vehicle frame; an end and the one-level sprocket wheel of rocking arm are arranged on the main shaft; step is arranged on the other end of rocking arm; torsion spring one end is arranged on the rocking arm; the other end is provided with on the vehicle frame; minor sprocket and secondary sprocket wheel are arranged on the countershaft, and the one-level sprocket wheel is connected with minor sprocket by the one-level chain, and the secondary sprocket wheel is connected with trailing wheel by the secondary chain.

When being advanced, the secondary sprocket wheel can drive the trailing wheel rotation, idle running when retreating, and described secondary sprocket wheel is provided with unidirectional needle bearing.

In order to protect foot drive device, to be convenient to the user and to stand, described foot drive device top is provided with the pedal of captiveing joint with vehicle frame.

In order to improve safety performance, described brake gear comprises brake handgrip, brake shoes, retracing spring, the brake handgrip is arranged on the handle, brake shoes is arranged on the vehicle frame by brake axle and is corresponding with trailing wheel, retracing spring one end is arranged on the brake shoes, the other end is fixed on the vehicle frame, and the brake handgrip is connected with brake shoes by brake cable.

For the ease of packing, transportation, collection, be provided with fold mechanism between the described vehicle frame and the person in charge's the breeches pipe.

After adopting said structure, because the utility model is provided with foot drive device, the user is by the foot-operated power that advances that provides, having overcome common Kickboard Scooter steps on ground with pedal and drives that the effort brought, speed are slow, the disadvantage of poor stability, not only easy and simple to handle, laborsaving during driving, and can improve speed of advance greatly and the ability that continues, and using thereby make the utility model both can be used as the body building equipment, the walking-replacing tool that can be used as fashion again uses.
