CN2437363Y - Front two- and rear one-wheels scooter turning device - Google Patents

Abstract

The utility model discloses a turning device for two-front wheel and one-rear wheel scooters, which comprises a vehicle frame, a handle, a transverse rod, a transverse draw rod, a wheel frame and wheels. The wheel frame is provided with a first plane and a second plane which are mutually vertical and adjacent. The transverse rod is fixedly connected with the front end of the vehicle frame, and both ends of the transverse rod are slantwise pivoted on one side of the first plane. Both ends of the transverse draw rod are respectively pivoted on the other side of the first plane. Therefore, when using, both ends of the transverse rod can be positioned at a high-low state by pressing the handle slantwise to make the vehicle incline towards one side, and the wheel also inclines and deflects. The rotating radius of the wheel frame is reduced, and the safety of turning is also guaranteed.

Description

A kind of tumbler of the first two back one wheel-type scotter

The utility model relates to a kind of the first two back one wheel-type scotter, refers to its tumbler especially.

Existing the first two back one wheel-type scotter is to establish the leader in a vehicle frame the place ahead, establish the front-wheel of two parallel pivot joints again at the vehicle frame front end, the rear end trailing wheel that is pivoted, vehicle frame stage casing appropriate location is established a pedal, being available for users to one rides on pedal, another pin is trampled ground and scooter is supportted forwards, when scooter slides forward, the user can both feet all receives and steps on pedal, treat that scooter was decelerated to the stopping time, trample ground forwards with other pin, both feet are all received stepped on pedal again the scooter support.So repetitiousness operation can reach motion and the dual purpose of lying fallow.But this structure can only support sliding, unidirectional advancing smooth-goingly, can not turn to, and is interesting less, for the teenager, lacks excitant.Therefore, the someone establishes the leader and a rotating shaft allows two front-wheels directly be turned to, but is parallel to each other and tool one spacing because of two front-wheels, make that its radius of turn becomes big when turning to, the wheel shaft because of two front-wheels is coaxial pivot joint again, turns to uncertain, overturning when causing easily that a front-wheel is liftoff to be lifted is absolutely unsafe.

The purpose of this utility model is exactly the tumbler that a kind of the first two back one wheel-type scotter will be provided, and the radius of turn in the time of can reducing the car body turning prevents and topples over, and has security.

For reaching above-mentioned purpose, the solution that the utility model is taked is as follows: a kind of tumbler of the first two back one wheel-type scotter, comprise members such as vehicle frame, handle, wheel carrier and wheel, its wheel carrier is provided with vertical and adjacent first plane and second plane mutually, wheel is articulated on second plane of wheel carrier, and handle stands on the vehicle frame front end admittedly; It also is provided with cross bar and drag link, and cross bar is fixed in the vehicle frame front end, and the cross bar two ends each tilt to be articulated in a side on wheel carrier first plane, the two ends of drag link are articulated in the opposite side on wheel carrier first plane respectively.

Described cross bar be provided with one with the wheel carrier first parallel plane pivot joint plane, the two articulate to link to each other, and the pivot joint plane of cross bar and vehicle frame are skewed affixed.

A buffering grain is respectively established in described vehicle frame front end both sides.

After adopting said structure, the user can utilize a side of the effect squeeze grip of self body weight or external force, can make the amesiality inclination of vehicle frame, make the cross bar two ends be the height shape, thereby make also tilted deflecting of wheel carrier, and, make the wheel body of two front-wheels also tilt because of drag link also deflection synchronously.Therefore, during turning, the wheel body of two front vehicle wheels both can reduce its radius of turn in rotation, can guarantee the security of turning again.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is a side-looking partial sectional view of the present utility model;

Fig. 4 is that master of the present utility model looks operation chart;

Fig. 5 is the operation chart of overlooking of the present utility model.

As Figure 1-3, the utility model comprises members such as vehicle frame 1, handle 2, cross bar 3, drag link 4, wheel carrier 5 and wheel 6.Its wheel carrier 5 tools are vertical and adjacent first plane 51 and second plane 52 mutually, and wheel 6 is articulated by second plane 52 of a wheel shaft 61 with wheel carrier 5, and handle 2 stands on vehicle frame 1 front end vicinity admittedly.Wherein:

Cross bar 3 is fixed in vehicle frame 1 front end, and cross bar 3 two ends each tilt to be articulated in first plane, 51 1 sides of wheel carrier 5, drag link 4 two ends also are articulated in the opposite side on first plane 51 of wheel carrier 5 respectively by a trunnion 41; Cross bar 3 as shown in FIG. is provided with and articulates plane 31, and at the two ends that articulate plane 31 each with first plane 51 pivot joints of a trunnion 311 with wheel carrier 5,31 on the pivot joint plane of cross bar 3 and 1 one-tenth of vehicle frame skewed affixed (being that cross bar 3 is skewed affixed with 1 one-tenth of vehicle frame); Respectively establish the buffering grain 11 that rubber or similar material are made in vehicle frame 1 front end both sides in addition, play cushioning effect when bumping for wheel carrier 5.

Shown in Fig. 4,5, the user utilizes self body weight or a side of squeeze grip 2 under the effect of external force, can make vehicle frame 1 amesiality inclination, make cross bar 3 two ends be the height shape, thereby make also tilted deflecting of wheel carrier 1, and because of drag link 4 also deflection synchronously, the wheel body 6 of two front-wheels is also tilted, when turning, still rotate, both can reduce radius of turn, guaranteed the security of turning again.

Claims (3)

1, a kind of tumbler of the first two back one wheel-type scotter, comprise members such as vehicle frame, handle, wheel carrier and wheel, its wheel carrier is provided with vertical and adjacent first plane and second plane mutually, and wheel is articulated on second plane of wheel carrier, and handle stands on the vehicle frame front end admittedly; It is characterized in that: also be provided with cross bar and drag link, cross bar is fixed in the vehicle frame front end, and the cross bar two ends each tilt to be articulated in a side on wheel carrier first plane, the two ends of drag link are articulated in the opposite side on wheel carrier first plane respectively.
