The specific embodiment

Consult Fig. 1, this is that figure is last to be the transparent view of this two-wheeled Kickboard Scooter 100 according to a kind of embodiment proposed by the invention.Two-wheeled Kickboard Scooter 100 includes parts such as vehicle frame 113, front component 110 and wheel assembly 111.Vehicle frame 113 needs to carry standing of operator, and the flat of vehicle frame can be used as tread plate and uses; The front end of vehicle frame 113 is connected with front component 110 through steering column jacket 160; The rear end of vehicle frame 113 is connected with wheel assembly 111.Front component 110 can supply the operator to control that Kickboard Scooter 100 directions use, and makes the operator can stably handle the operation of Kickboard Scooter 100.

In this embodiment, front component 110 is to include parts such as front-wheel 112, vertical handgrip 151 and handle pipe 150.Front-wheel 112 is the ends that are arranged on vertical handgrip 151 regularly.Handle pipe 150 is matched with vertical handgrip 151.Make the operator rotate handle pipe 150, front-wheel 112 is turned to, reach and handle the effect that Kickboard Scooter 100 turns to.

In this embodiment, the trailing wheel in the wheel assembly 111 is to adopt conventional wheel 122.

In the front component 110, when front-wheel 112 rotations, it is around 140 rotations of spin axis; When the operator turned to handle pipe 150, front-wheel 112 integral body were being followed and are being turned to, and it rotates and turns to axis 141.It is to be noted that especially front-wheel 112 is rearmounted, promptly is spin axis 140 and steer axis 141 mutually exclusives, and steer axis 141 is positioned at the front of spin axis 140, as shown in Figure 1.The postposition of front-wheel 112 makes it have the function (being that wheel both can spin, the function that can whole turn to again) of similar castor (Caster).Front component 110 also includes a spring 130, and its end is connected with front component 110, and the other end is connected with vehicle frame 113.130 pairs of front components 110 of spring are applied with bias voltage, after making front-wheel 112 turn to capable cancelling because the bias effect of spring 130, can make front-wheel 112 recover to get back to original towards.In other words, 130 pairs of front-wheels of spring 112 produce the directed effect of bias voltage, make front-wheel 112 tend to the position that keeps rearmounted.Because front-wheel 112 is parts of front component 110,, make vertical handgrip 151 and handle pipe 150 all trend towards recovering the position that moves ahead towards straight so 130 pairs of front components 110 of spring all produce the directed effect of bias voltage.The operator no matter when; With vertical handgrip 151 or handle pipe 150 behind operator's a left side or right steering; When the power that turns to when removing subsequently because the effect of above-mentioned bias voltage, front component 110 keep rearmounted in; And can be returned to they original towards, keep towards Kickboard Scooter rectilinear direction longitudinally.

On the two-wheeled Kickboard Scooter 100, the postposition of front-wheel 112 and the mechanism that the bias voltage oriented phase combines make operator's pin stand on the tread plate of vehicle frame 113, and laterally swinging with pin just can produce power to Kickboard Scooter, drive Kickboard Scooter 100 and have advanced.Said mechanism makes two-wheeled Kickboard Scooter 100 except the type of drive of routine with the feet step on the ground, has increased a kind of type of drive without the feet step on the ground.Be noted that the Kickboard Scooter 100 of this structure, different with the two-wheeled Kickboard Scooter of routine, it can also make the action of diversified " spin " or " drift ".

The last represented spring 130 of Fig. 1 is coil springs that are connected with front component 110, yet also can adopt other elastic element to reach same effect, comprises elastic elements such as available rubber tape, bellows.Also can realize the effect that bias voltage is directed with the elastic element that is attached to point-like, hoop shape or ring-type torsional spring type in the handlebar rotating shaft 151.Be pointed out that in passing on the front-wheel 112 of front component, parts such as wheel guard and brake facing can be set, prior art in the industry can both realize, has no longer detailed at this.It should be appreciated that; Can replace single front-wheel or trailing wheel with two wheels arranged side by side; This is the stability that increases operation with the method for ground area of contact with increasing, and two-wheel arranged side by side is actually the structure that equals single-wheel, and this technology is also known by the insider.

Fig. 2 illustrates the two-wheeled Kickboard Scooter 200 according to another kind of embodiment proposed by the invention.Equally, two-wheeled Kickboard Scooter 200 includes parts such as vehicle frame 213, front component 210, wheel assembly 211.Vehicle frame 213 also is to want to carry standing of operator; The front end of vehicle frame 213 is connected with front component 210 through steering column jacket 260; The rear end of vehicle frame 213 is connected with wheel assembly 211.Front component 210 also can supply the operator to control that Kickboard Scooter 200 directions use.Front component 210 is made up of front-wheel 212,

vertical handgrip

251 and 250 of the handle pipe matched with it.The trailing wheel 222 of wheel assembly 211 also is to adopt conventional wheel.

The configuration of the last handle pipe 250 of Fig. 2 is somewhat different with Fig. 1, and this is because there has been an angle front of steer axis 241, makes the operator feel comfortable place for handle pipe 250 is arranged on, and makes the operator be convenient to control the direction of Kickboard Scooter 200.The scheme of Fig. 2 is to be designed to interconnected two parts up and down to the vertical handgrip in the front component 210 251, and is middle with universal rotating shaft connection, and some angles are arranged between two parts up and down slightly.Handle pipe 250 with the first half of vertical handgrip 251 attached to; The latter half of vertical handgrip 251 is connected with vehicle frame 213 through steering column jacket 260, with steer axis 241 in-lines.Certainly, for this purpose, also have the design plan of other prior aries also can reach similar effects.The technology of universal rotating shaft is known by the insider.

The steer axis 141 of two-wheeled Kickboard Scooter 100 shown in Figure 1; Generally perpendicular basically with ground, or steer axis has an angle that retreats (on vertical vertical plane surface of Kickboard Scooter, to say that the upper end of vertical handgrip is near the operator; After; The lower end of vertical handgrip is slightly away from the operator, preceding, so we claim that steer axis has an inclination angle backward).With the above-mentioned angle that retreats Comparatively speaking, and front-wheel 212 is not only rearmountedly on the Kickboard Scooter 200 shown in Figure 2, and steer axis 241 is with respect to ground-surface perpendicular line an angle that turns forward (seeing the lower part of vertical handgrip 251) being arranged.This angle that leans forward of the steer axis 241 of front-wheel in the front component makes front component utilize the effect of gravity to have the directed function of bias voltage.

Postposition of this programme and the design at inclination angle forward; Make front-wheel 212 obtain the functional similarity of bringing into play with Fig. 1 medi-spring 130; Here be that gravity (terrestrial attraction) provides bias voltage, replaced the bias voltage that provides by elastic element, make front-wheel 212 and whole front component 210 have the directed function of bias voltage.

Because on the two-wheeled Kickboard Scooter 200, front-wheel 222 has same bias voltage orientating function, when the power that turns to when removing subsequently, front component 210 also can be returned to they original towards, make front-wheel 212 tend to the position that keeps rearmounted.So the operator can drive Kickboard Scooter 200 equally and do " S " having advanced of shape.
