Abstract

Disclosed is a treading dynamic device of scooters which is comprised of a scooter body, a footplate, a box-shaped shell, an outer tube of the axis, a transmission gear unit, a slide sleeve, a brake rod and a compression spring. Double real wheels are arranged at the tail end of the footplate and a through hole is arranged at the terminal end of the footplate; the box-shaped shell is arranged at the bottom end on the tail of the footplate. The outer tube of the axis is sleeved on the double real wheels in linkage type; the transmission gear unit is composed of a plurality of mutually meshed small gears and large one-way gears through gear shift, so that the outer tube of the axis of the ear wheels can be turned around and transmitted forward; an open slot is arranged on one sidewall of the slide sleeve; the top end of the slot aims at the through hole of the footplate; the open slot aims at a first pinion; one side of the brake rod body is provided with row teeth; the row teeth and the first pinion meshedly arranged in the slide sleeve; the top end of the rod body passes through the through hole of the footplate and is connected with a small footplate; the compression spring is arranged on the bottom end of the brake rod so that the brake rod can be compressed and reset by the support of the spring. Through the repeated trample and release movements of the small footplate, the running scooter body can produce appropriate acceleration driving force. The utility model is safe and convenient in use.

Description

The pedal power device of Kickboard Scooter

Technical field

The utility model relates to vehicle, relates in particular to a kind of pedal power device of Kickboard Scooter.

Background technology

Existing Kickboard Scooter, mainly form by a direction lever and a wheel cap formula braking vane that supplies biped to step on upright stretcher, front and back wheel, control front vehicle wheel rotation direction, during use, draw the back of landing frequently by a pin, thrust is slided in generation, this existing Kickboard Scooter is controlled sense because of entertaining outdoor activity performance and the simple and easy of bicycle with slippery plate, so since the listing, has been subjected to all ages customer's welcome deeply.But this existing coaster plate can not be under the situation that keeps normal running, and the mode that adopts pin not land is quickened, and still have inconvenience in the use, and safety performance is relatively poor.

Summary of the invention

The purpose of this utility model is for overcoming the shortcoming that existing Kickboard Scooter pedal power mode exists, and provide a kind of pedal power device of Kickboard Scooter, it is by trampling and decontrol the action of little pedal repeatedly, make the Kickboard Scooter car body in advancing to produce the suitable propulsion power of acceleration again, the sliding action that needn't adopt pin to land is controlled the power that slides of Kickboard Scooter, and is safe and convenient to use.

The technical scheme that its technical matters that solves the utility model adopts is:

The pedal power device of the utility model Kickboard Scooter, form by Kickboard Scooter car body, stretcher, box-shaped enclosure, axle center outer tube, driving gear set, sliding sleeve, fixed pawl and compression spring, wherein, the stretcher tail end is provided with two rear wheels, and the terminal appropriate location of stretcher is provided with a through hole; Box-shaped enclosure is located at place, bottom, stretcher end; The axle center outer tube is the sheathed pair of rear wheel in linkage type ground; Driving gear set is made up of several miniature gearss and big ratchet, and miniature gears and big ratchet speed change bridle joint make rear wheel axle center outer tube turn round transmission forward; Sliding sleeve one sidewall is provided with fluting, and the stretcher through hole is aimed on its top, and fluting is aimed at first miniature gears; The fixed pawl body of rod one side is provided with toothrow, being located in the sliding sleeve of this toothrow and first pinion, and body of rod top passes and connects a little pedal along the stretcher through hole; Compression spring is located at the fixed pawl bottom, makes that fixed pawl is compressible, the bullet support resets.

The specific embodiment

Consult Fig. 1 to shown in Figure 4, the pedal power device of the utility model Kickboard Scooter, it is made up of Kickboard Scooter car body, stretcher 1, box-shaped enclosure 11, axle center outer tube 10, driving gear set, sliding sleeve 16, fixed pawl 14 and compression spring 17, wherein, stretcher 1 front end lock has held direction lever 2, and direction lever 2 bottom bearings are provided with front vehicle wheel 3, and stretcher 1 end is provided with by axle center 6 and supports two rear wheels 4, rear wheel 4 tops are hung with brake facing 5, and stretcher 1 terminal appropriate location is provided with a through hole 1a; Box-shaped enclosure 11 is located at place, bottom, stretcher 1 end; Outer tube 10 two ends in axle center are the sheathed pair of rear wheel 4 in continuous action relation ground (or direct sintering is fixed); Driving gear set is made up of several miniature gearss 12 and big ratchet 13, the coaxial first ratchet 13a of the first miniature gears 12a interlock turns round forward, the second miniature gears 2b is engaged in the first ratchet 13a, the rest may be inferred that bearing is arranged in the shell 11 for the coaxial second ratchet 13b reversed turning of transmission whereby, wherein, but the most last ratchet 13e interlock rear wheel axle center outer tube 10 turns round forward, and directly meshes with penult ratchet 13d; Sliding sleeve 16 1 sidewalls are provided with fluting 16a, and stretcher 1 through hole 1a is aimed on its top, and fluting 16a aims at the first miniature gears 12a wheel rim; Fixed pawl 14 bodies of rod one side is provided with toothrow 14a, and this toothrow 14a and the first miniature gears 12a ingear are located in the sliding sleeve 16, and body of rod top passes and connects a little pedal 15 along stretcher 1 through hole 1a; Compression spring 17 is located at fixed pawl 14 bottoms, makes that fixed pawl is 14 compressible, the bullet support resets.

Consult Fig. 3 to shown in Figure 5, when the pedal power device of the utility model Kickboard Scooter uses, when Kickboard Scooter generally slides forward, the last ratchet 13e become motionless state by rear wheel axle center outer tube 10 lost motion voluntarily, when Kickboard Scooter backward during back skating, the last ratchet 13a will drive simultaneously gyroscopic movement backward by axle center outer tube 10, at this moment, penult ratchet 13d becomes the not lost motion of interlock axle center 6a, so that the Kickboard Scooter car body has the performance of normal front and back art skating activity, when the Kickboard Scooter in advancing is tending towards slow, only need a pin is stepped down in the action of trampling repeatedly and decontroling on the little pedal 15, just can produce and quicken thrust power again, promptly, in the time of the downward pressure drop of fixed pawl 14, the first miniature gears 12a is with regard to the coaxial first ratchet 13a of interlock revolution forward together, thereby make the second miniature gears 12b that is engaged on first ratchet quicken its coaxial second ratchet 13b reversed turning of interlock, and the last ratchet 13e interlock rear wheel axle center outer tube 10 that makes by that analogy rotates forward together, thereby rear wheel 4 is produced quicken thrust power again, and shore when resetting by compression spring 17 when fixed pawl 14, the first miniature gears 12a concentric 6b, the first ratchet 13a of end in addition can keep motionless state, makes the unlikely revolution backward of power.

The pedal power device of the utility model Kickboard Scooter, the accelerating ability again of its rear wheel 4 is directly proportional with the pressure drop rate of fixed pawl 14, that is and, the pressure drop rate of fixed pawl 14 is fast more, and it is fast more that driving gear set drives the rotating speed of rear wheel 4; Otherwise these fixed pawl 14 pressure drop rates are slow more, and it is slow more that driving gear set drives the rotating speed of rear wheel 4, and therefore, the user can control the speed that slides arbitrarily by the speed of foot-operated fixed pawl.

The pedal power device of the utility model Kickboard Scooter, the power of acceleration again project organization by non-energy formula, reaching is not influencing under the existing operating conditions of Kickboard Scooter, increase pin again and do not landed practicality and the mobility of quickening again, make it use more convenient and safety, reach design purpose.
