Abstract
A swinging tricycle comprises a frame, a saddle, a rear wheel, two front wheels and pedals, wherein the rear wheel is driven by the pedals via a chain transmission mechanism, the front end of the frame is provided with a parallel four-link mechanism, the parallel four-link mechanism consists of a first transverse bar, two lateral bars and a second transverse bar, wherein the first transverse bar is fixed at the front end of the frame, the two lateral bars are hinged on two sides of the transverse bar, the second transverse bar is hinged at the other ends of the two lateral bar, and the two front wheels are respectively mounted on the two lateral bars. When using, the two front wheels can be reversed easily under action of the parallel four-link mechanism, and then actions of the parallel four-link mechanism are controlled by swinging of the body of a user. The swinging tricycle has the advantages of novel shape, convenient operation, safe use, high entertainment and the like.
Description
Technical field:

The utility model content:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of modern design, recreational strong, easy to operate, safe in utilization, lower-cost three-wheel to wave bicycle.
The three-wheel that provides according to the utility model waves bicycle, comprise vehicle frame, seat cushion, trailing wheel, two front-wheels and stretcher, described trailing wheel is driven by chain drive by stretcher, described vehicle frame front end is provided with a parallel four-bar linkage, described parallel four-bar linkage by first cross bar that is fixed on the vehicle frame front end, be hinged on two side levers of cross bar both sides, form with two side lever other end pivotallys attached, second cross bar, described two front-wheels are installed in respectively on two side levers.
In addition, the utility model also has following attached technical characterictic:
Described first cross bar is an abundant rigidity body of rod, and described two side levers are two U-shaped plate bodys that are provided with in opposite directions, and described second cross bar is the less indent arc of a radian.
It is interior and hinged by the upper and lower end wall of rivet and two side levers to be placed in two side levers in the two ends of described first cross bar, and described second cross bar is located at the upper end of two side levers, and the two ends of second cross bar are hinged with the upper end wall of two side levers respectively.
Respectively be fixed with a screw rod on the lateral wall of described two side levers, described two front-wheels are installed in rotation on respectively on the cooresponding screw rod, and all lock by outboard nut.
Described cushion front end is installed with an arm-rest frame.
Described vehicle frame is made up of cushions support bar, protrusive rod and back vent, and described parallel four-bar linkage is arranged on the protrusive rod front end.
Described two front-wheels are less than 1/4th diameters of described trailing wheel.
The three-wheel that provides according to the utility model waves bicycle, has following advantage with respect to prior art:
At first, the utility model is provided with parallel-crank mechanism at the vehicle frame front end, and this mechanism can realize the light commutation of front-wheel, and adopts the front-wheel commutation more to meet people's operating habit, thereby one on the one hand improved the comfort feature of operation, also increased the safety in travelling on the other hand.
Secondly, tricycle of the present utility model does not have the designing car handle, modern design, during commutation, the action of controlling parallel-crank mechanism by the swing of user's health realizes, cooperation that need not handlebar, thereby improved the recreational of tricycle greatly, increased the interest when playing.
Once more, the utility model is simple in structure, and volume is little, and vehicle frame only is made up of cushions support bar, protrusive rod and back vent, thereby has also reduced the manufacturing cost of bicycle.
Description of drawings:
Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is the schematic top plan view of vehicle frame front end commutating structure in the utility model;
Fig. 3 is the stagewise cutaway view scheme drawing of A-A direction among Fig. 2.
The specific embodiment:
Referring to figs. 1 through Fig. 3, the three-wheel that provides according to the utility model waves bicycle, comprises vehicle frame 1, seat cushion 2, trailing wheel 3, two front-wheels 4 and stretcher 5, and trailing wheel 3 is driven by chain drive 6 by stretcher 5.Vehicle frame 1 front end is provided with a parallel four-bar linkage 7, parallel four-bar linkage 7 by first cross bar 71 that is fixed on vehicle frame 1 front end, be hinged on two side levers 72 and 73 of cross bar 71 both sides, form with two side levers, 72,73 other end pivotallys attached, second cross bar 74, two front-wheels 4 are installed in respectively on two side levers 72,73, during use, two front-wheels 4 can be realized light commutation under the action of parallel four-bar linkage 7, the action of parallel four-bar linkage 7 is controlled according to the swing of user's health.
As mentioned above, first cross bar 71 is an abundant rigidity body of rod, two side levers 72,73 are two U-shaped plate bodys that are provided with in opposite directions, it is interior and hinged by the upper and lower end wall of rivet and two side levers 72,73 to be placed in two side levers 72,73 in the two ends of first cross bar 71, herein, the connection structure of the structure of first cross bar 71 and two side levers 72,73 and first cross bar 71 and two side levers 72,73, can guarantee that parallel four-bar linkage 7 has enough intensity, to be suitable for the frequent commutation work of front-wheel, prolong its service life.Second cross bar 74 is the less indent arc of a radian, second cross bar 74 is located at the upper end of two side levers 72,73, and the two ends of second cross bar 74 are hinged with the upper end wall of two side levers 72,73 respectively, the arcuate structure of second cross bar 74 and can make the action of parallel four-bar linkage 7 light and handy more with the connection structure of two side levers, flexibly improves the recreational of the comfort feature of operation and use.
Respectively be fixed with a screw rod 721,731 on the lateral wall of two side levers 72,73, two front-wheels 4 are installed in rotation on the cooresponding screw rod 721,731 by bearing respectively, and all pass through outboard nut 8 lockings, this connection mode makes that the installation and removal of two front-wheels are all very convenient.Cushion 2 front ends are installed with an arm-rest frame 9, and during use, the user can guarantee the balance of health with hand steered on this arm-rest frame.
