At present, many toy cars are arranged on the market, mainly contain with regard to its type of drive: a kind of is by battery traction; Another kind is the transmission device that roller dish and chain are formed, and drives by riding.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of new-type children's hand-car safe in utilization that only just can advance or retreat by steering wheel rotation in waving.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: children's hand-car comprises vehicle body, is installed in a pair of rear wheel of body tail, a pair of big front vehicle wheel of vehicle body fwd that is installed in, it is characterized in that also comprising a cover auxiliary wheel device, its auxiliary wheel device comprises the front vehicle wheel support that has crossbeam, auxiliary big wheel and a pair of unsettled accessory cart wheel; The front vehicle wheel support is by perpendicular to the axle mounting of the vehicle body downside in the front portion of described vehicle body, described axle is vertically mounted on the middle place of described crossbeam, the top end of axle is provided with a bearing circle, and an end of described crossbeam is by the auxiliary a pair of auxiliary big wheel of big wheel axle mounting; Described two big front vehicle wheels run through crossbeam by big front truck wheel shaft and are installed in the vehicle body both sides.The afterbody of vehicle body also can have a push rod, and push rod is fixed on the vehicle body by blocking device.
The beneficial effects of the utility model are: adopt above-mentioned technical scheme, can described children's hand-car be advanced in wigwag motion or retreat by steering wheel rotation, both need not ride, also no longer use other power, opened up a kind of new-type carriage for children, and the adult can grasp the balance and the safety of carriage for children by the push rod of tail of body, ensures children's safety.
The utility model is described in further detail below in conjunction with the drawings and the specific embodiments.
Description of drawings
Fig. 1 is the overall schematic of a kind of embodiment of the utility model.
Fig. 2 is the bottom schematic view of Fig. 1.
Fig. 3 is an auxiliary wheel apparatus structure scheme drawing among Fig. 1.
Mechanical analysis scheme drawing when Fig. 4 is motion.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the embodiment of a kind of children's hand-car of present embodiment comprises vehicle body 1, is installed in a pair of rear wheel 2 of body tail, an a pair of big front vehicle wheel 3 of vehicle body fwd and the cover auxiliary wheel device of being installed in; Its auxiliary wheel device comprises front vehicle wheel support 4, auxiliary big wheel 5 and a pair of unsettled accessory cart wheel 6; Front vehicle wheel support 4 is by being installed in the downside of the front portion of described vehicle body 1 perpendicular to the axle 7 of vehicle body, front vehicle wheel support 4 has a crossbeam, described axle 7 is vertically mounted on the middle place of described crossbeam, the top end of axle 7 is provided with a bearing circle 8, and bearing circle drives axle can make auxiliary wheel device 360 degree rotate; One end of described crossbeam is installed a pair of auxiliary big wheel 5 by auxiliary cart wheel shaft 9; Two big front vehicle wheels 3 run through crossbeam by big front truck wheel shaft 10 and are installed in vehicle body 1 both sides; The afterbody of vehicle body 1 has a push rod 11, and push rod 11 is fixed on the vehicle body 1 by blocking device; The bottom is equipped with the stretcher 12 that can fold in the vehicle body 1 of children's hand-car.
As shown in Figure 4, the principle of work of the utility model children hand-car is: when children drive, be sitting on the seat cushion, pin steps down on the stretcher 12 of expansion, as long as with hand steering wheel rotation 8 clockwise or counterclockwise, children's hand-car just can about to put forward or move right.To clockwise rotate bearing circle is example, when clockwise rotating bearing circle, drives auxiliary big wheel 5 motions by axle 7, this moment, children's hand-car had a centripetal force to the right, so vehicle body is tilted to the right, the right redundant big wheel at Y place and ground-surface contact force are strengthened, and friction force strengthens; And the left redundant big wheel at X place and ground-surface contact force reduce accordingly, so clockwise rotating under the application force of bearing circle, are axle with the right redundant big wheel at Y place, and the left redundant big wheel at X place can move to the upper right side.Above-mentioned situation appears in meeting under spending greater than the situation of 0 degree less than 90 when α angle among Fig. 4 and β angle.Because the motion of above-mentioned wheel has one to point to the top-right F of the main force at the O at axle 7 places point place, therefrom also can see the component F of directed straight ahead
1The component F right-hand with sensing
2Under the effect of above-mentioned power, a pair of rear wheel also and then rotates, so whole children's hand-car can move to the right front.Wherein, the power of ordering about the motion of children's hand-car is to point to O to order, and that is to say, for the O point, big auxiliary big wheel is adjusted to the back that O is ordered, and when turning left and right bearing circle, children's hand-car is proal on the whole.Otherwise, for the O point, auxiliary big wheel is adjusted to the front that O is ordered, when turning left and right bearing circle again, children's hand-car then rearward moves.Rotate because children's hand-car bearing circle of the present utility model is 360 degree, assist big wheel just to adjust to the place ahead that O is ordered so steering wheel rotation surpasses 180 degree.
In like manner, when inhour is rotated bearing circle, drive auxiliary big wheel motion by axle, because be inhour, so children's hand-car moves to the left front.When a big front vehicle wheel is adjusted at O point back, during steering wheel rotation, children's hand-car can advance in wigwag motion again and again.When auxiliary big wheel being adjusted at O point front, during steering wheel rotation 8, children's hand-car can retreat in wigwag motion again and again.
The big front vehicle wheel of children's hand-car makes the car on the go stablize the left and right sides balance of vehicle body, accessory cart wheel 6 is unsettled always, when in driving children hand-car is advancing, running into uphill road, under the gradient reaches certain situation, because contacting to earth of accessory cart wheel 6 can make children's hand-car retreat, when the gradient is big, overturn to prevent children's hand-car.The afterbody of children's hand-car car vehicle body 1 has a push rod 11, and push rod 11 is fixed on the vehicle body by blocking device, and push rod makes children's hand-car and to move by adult's implementation, and can protect children's safety.For convenience, the bottom is equipped with the stretcher 12 that can fold in the vehicle body 1 of children's hand-car, and the stretcher 12 that can fold can adopt telescopic folding also can adopt collapsible folding, and the time spent can not fold stretcher, in case take up room, and the health of maintenance stretcher.
