Abstract

The utility model relates to a scooter. The scooter comprises a handle, a front fork, a front wheel, a rear wheel frame and two rear wheels, wherein the handle, the front fork and the front wheel are arranged at the front part of a pedal; the rear wheel frame and the two rear wheels are arranged at the rear part of the pedal; an axle is fixedly arranged on the rear wheel frame; the two rear wheels are respectively arranged on the two sides of the rear wheel frame via the axle; an included angle Theta between the axes of the two rear wheels is an obtuse angle; the two rear wheels are inverted V-shaped. By adopting the structure, when the scooter takes a sudden turn or inclines, one rear wheel of the scooter raises, the point of the axle of the rear wheel in contact with the ground is opposite to the toppling direction of the scooter, as a result, the risk of the toppling of similar scooters is effectively lowered.

Description

Kickboard Scooter

Technical field

The utility model relates to a kind of Kickboard Scooter.

Background technology

Modal three-wheel scooter on market, is by pedal, is located at handlebar, front fork and the front-wheel of pedal front portion; Two trailing wheels and the mobilizable braking top of being located at pedal rear portion form.The handlebar of such Kickboard Scooter is scalable, is collapsible and is connected between handlebar and pedal, have take up room little, be convenient to the advantages such as packed and transported.But the wheelspan of two trailing wheels of such Kickboard Scooter is shorter, and two trailing wheels and ground are vertical configuration, trailing wheel perk during turning, the direction that now sensing of the axial line of trailing wheel wheel is toppled over Kickboard Scooter is consistent, the main user's of dependence manipulation makes it keep balance, but the amplitude that runs into sharply turning or turning is excessive a little, just there will be and the dangerous situation such as fall down.

Summary of the invention

In view of the deficiency that background technology exists, the technical problems to be solved in the utility model is to provide a kind of two trailing wheels and is " eight " word layout, during turning, can reduce the Kickboard Scooter of toppling over risk.

In order to solve the problems of the technologies described above, the utility model is realized by the following technical solutions: a kind of Kickboard Scooter, comprise handlebar, front fork and the front-wheel of being located at pedal front portion, be located at rear wheel frame and two trailing wheels at pedal rear portion, on described rear wheel frame, be fixedly installed wheel shaft, two described trailing wheels are located at respectively the both sides of rear wheel frame by wheel shaft, the angle theta between the axial line of the wheel of two described trailing wheels is obtuse angle, and two described trailing wheels become " eight " word shape.

Beneficial effect: two trailing wheels of the present utility model adopt " eight " character wheel layout, when this Kickboard Scooter sharply turning or appearance inclination, a trailing wheel perk of this Kickboard Scooter, the opposite direction that the sensing of the axial line of the wheel of that trailing wheel contacting with ground and Kickboard Scooter are toppled over, effectively reduces the risk that such Kickboard Scooter is toppled over.

The scope of the angle theta between the axial line of the wheel of two trailing wheels of the present utility model in the time of 115 °～155 °, its travel and the resultant effect of packed and transported best.

Wherein two that is shaped as of a class wheel shaft of the present utility model is tilted to, by-level " " shape.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:

As shown in Figure 1: Kickboard Scooter of the present utility model comprises handlebar 2, front fork 3 and the front-wheel 4 of being located at pedal 1 front portion, be located at the rear wheel frame 5 at pedal 1 rear portion, two trailing wheels 6 and mobilizable braking top 8.

With reference to Fig. 2, Fig. 3 and Fig. 4, the structure of first kind rear wheel frame of the present utility model and wheel shaft and as follows with the relation of pedal: one end of described rear wheel frame 5 is fixed on the bottom surface at pedal 1 rear portion, on the lower surface of rear wheel frame 5 other ends, offer the breach 52 mating with wheel shaft 7 external diameters, the middle part of rear wheel frame 5 is provided with the bolt hole 51 passing for bolt 81, and braking top 8 is arranged on the rear portion of pedal 1 by bolt 81; The two that is shaped as of described wheel shaft 7 is tilted to, by-level " " shape, the two ends of this wheel shaft 7 are provided with screw thread.Make wheel shaft 7 keep state vertically upward of two ends and by welding, wheel shaft 7 is fixed on to breach 52 places of rear wheel frame 5 lower surfaces.In the both sides of wheel shaft 7, be respectively charged into packing ring 10, wheel 6, then screw on nut 9.Now, the angle theta between the axial line 601 of the wheel of two trailing wheels 6 is obtuse angle, described 6 one-tenth " eight " word shapes of two trailing wheels.When the scope of angle theta is during at 115 °～155 °, its resultant effect is best: when the scope of angle theta is during >90 ° of 180 ° of > θ, when angle theta more approaches 90 °, wheel just more tilts, the overturning-preventing ability of two trailing wheels is just stronger, but the packaging volume of Kickboard Scooter also can be larger; When angle theta more approaches 180 °, wheel and ground are just more vertical configuration, and the overturning-preventing ability of two trailing wheels is just more weak, but the packaging volume of Kickboard Scooter will be less.In 40 of angle theta middle, spend just for 115 °～155 °, the resultant effect of its enforcement and packed and transported is best.

By the combination of above each parts, as shown in Figure 5, when common Kickboard Scooter sharply turning or appearance inclination, a trailing wheel perk of this Kickboard Scooter, the direction that now sensing of the axial line 602 of trailing wheel wheel is toppled over Kickboard Scooter is consistent; When adopting the Kickboard Scooter sharply turning of " eight " character wheel layout or occurring tilting, a trailing wheel perk of this Kickboard Scooter, the sensing of the axial line 601 of the wheel of that trailing wheel contacting with ground and the opposite direction that Kickboard Scooter is toppled over, effectively reduce the risk that such Kickboard Scooter is toppled over.

With reference to Fig. 6, Fig. 7, Fig. 8, the structure of Equations of The Second Kind rear wheel frame of the present utility model and wheel shaft and as follows with the relation of pedal: the fixed part 53 of pedal 1 bottom surface is fixed in one end formation one of described rear wheel frame 5, the other end of rear wheel frame 5 forms one in order to the fixing wheel shaft fixed part 54 of wheel shaft 7, the monosymmetric wheel shaft fixed orifice 55 that is provided with of wheel shaft fixed part 54, the middle part of rear wheel frame 5 is provided with the bolt hole 51 passing for bolt 81, and braking top 8 is arranged on the rear portion of pedal 1 by bolt 81; Two both sides that are fixed on wheel shaft fixed part 54 that wheel shaft 7 tilts by wheel shaft fixed orifice 55, and two wheel shafts 7 are symmetrical.On two wheel shafts 7, be respectively charged into packing ring 10, wheel 6, then screw on nut 9.Now, the angle theta between the axial line 601 of the wheel of two trailing wheels 6 is obtuse angle, described 6 one-tenth " eight " word shapes of two trailing wheels.When the scope of angle theta is during at 115 °～155 °, the resultant effect best (with noted earlier identical, repeating no more) of its enforcement and packed and transported.

Combination by above each parts, when adopting the Kickboard Scooter sharply turning of " eight " character wheel layout or occurring tilting, a trailing wheel perk of this Kickboard Scooter, the sensing of the axial line 601 of the wheel of that trailing wheel contacting with ground and the opposite direction that Kickboard Scooter is toppled over, effectively reduce the risk that such Kickboard Scooter is toppled over.
