Abstract
The utility model relates to a bicycle for children, which has a bicycle frame, a steering handlebar, a front fork, a front wheel, a rear wheel, a rocker arm and a crank connecting rod mechanism. The lower end of the front fork is mutually connected with the wheel shaft of the front wheel. The upper end of the rocker arm is mutually connected with the steering handlebar, and the lower end is mutually connected with the upper end of the front fork through a universal joint. The two ends of the crank connecting rod mechanism are respectively mutually connected with the rocker arm and the wheel shaft of the rear wheel, the connecting end of the rocker arm is hinged with a sliding ring which is sheathed and positioned at the middle part of the rocker arm, and the sliding ring can slide backwards and forwards along the longitudinal direction of the rocker arm. The bicycle for children can realize manual control steering at the same time hand driving; the bicycle for children has the characteristics of convenient operation, safety and reliability, and can make the bicycle models more diversified.
Description
The utility model relates to a kind of carriage for children.
China's utility application discloses a kind of dual-purpose toy tricycle for No. 8721568, and this perambulator mainly is made of vehicle frame, handlebar, front fork, joystick, piston crank mechanism and forward and backward wheel.By rocking back and forth joystick and through the transmission of crank connecting rod mechanism, can drive trailing wheel and rotate, car is moved ahead.In this perambulator, when driving with joystick, joystick and front fork are disengaged position, and the bicyclist can only utilize the travel direction that is fixed in the foot-operated control car on the front-wheel.Obviously, the operating mode of this kind foot control direction certainly will cause difficulty to the operator, even causes the accident thus., safety more convenient for the use that makes this type of perambulator are necessary it is further improved.
The purpose of this utility model is that the steering structure to above-mentioned existing perambulator improves, and a kind of easy to operate, safe and reliable hand carriage for children is provided.
Carriage for children of the present utility model has vehicle frame, bogie car handle, front fork, front-wheel, trailing wheel, rocking arm and piston crank mechanism.The upper end of front fork is installed in turning in the axle bed of vehicle frame, and its lower end and car front-wheel wheel shaft join.The two ends of piston crank mechanism link to each other with rear axle with rocking arm respectively.The upper end of rocking arm links to each other with the bogie car handle, and the lower end joins by the upper end of universal-joint and front fork especially.The rocking arm coupling end of piston crank mechanism is hinged with slip ring, and this slip ring sleeve is located at the rocking arm middle part, can slide along vertical front and back of rocking arm.When using carriage for children of the present utility model, because the lower end of rocking arm joins by universal-joint and front fork, so rocking arm both can rock back and forth, and can drive the front fork rotation again.Also that is to say that rocking arm both can drive rear wheel movement by piston crank mechanism, realize the driven by shaking function of similar perambulator, front fork is rotated, realize the control that turns to of perambulator.Owing to be connected by the above-mentioned slip ring that is placed on the rocking arm between rocking arm and the piston crank mechanism, thereby can guarantee that rocking arm can rotate and shake neatly.In the utility model, piston crank mechanism can directly adopt the version of existing similar perambulator.
Perambulator of the present utility model is compared with existing similar perambulator owing in hand process, still can manual control turn to, thereby have be convenient to operate, safe and reliable characteristics.Simultaneously, change into after manual control turns to, this carriage for children not only can be made into the three-wheel vehicle form, also can be made into two comparatively short wheel bicycle forms, makes vehicle more diversified.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
Fig. 1 is the structural representation of carriage for children among the embodiment 1.
Fig. 2 is the structural representation of carriage for children among the embodiment 2.
Embodiment 1:
As shown in Figure 1, in the present embodiment carriage for children have vehicle frame 1, bogie car 2, front fork 3, front-wheel 4, trailing wheel 5, rocking arm 6 and piston crank mechanism.Piston crank mechanism is made of montant 9, cross bar 10 and crank 11.The upper end of front fork 3 is installed in turning in the axle bed 16 of vehicle frame, and the wheel shaft of its lower end and front-wheel 4 joins.The upper end of rocking arm 6 links to each other 2 with bogie car, and the lower end joins by the universal-joint 8 of special setting and the upper end of front fork 3.The two ends of piston crank mechanism link to each other with the wheel shaft of rocking arm 6 with trailing wheel 5 respectively.Be hinged with the slip ring 7 that is placed on the rocking arm middle part at the rocking arm coupling end (being the upper end of montant 9 herein) of piston crank mechanism, piston crank mechanism is realized and being connected of rocking arm by this slip ring.Slip ring 7 can slide along vertical front and back of rocking arm 6.In the present embodiment, when rocking arm 6 is shaken in front and back,, can drive trailing wheel 5 and rotate by the transmission of piston crank mechanism.When rotating rocking arm, can drive front fork 3 and rotate, the control direction of traffic.Certainly, from the angle of being convenient to operate, the user normally makes rocker arms roll and rotation by handlebar 2.In rocking arm rocked back and forth process, slip ring 7 was along the vertical upper and lower slip of rocking arm, and the maintenance piston crank mechanism is connected with rocking arm.Simultaneously, when rocking arm rotated, movable sleeve slip ring placed on it also can not hinder its rotation.Carriage for children among the embodiment has set up foot-operated 12 and guard bar 13.Foot-operated 12 are fixed on the front wheel spindle, so that the beginner drives with pin.After the beginner learns the driven by shaking driving, also can shed riding 12.The setting of guard bar 13 is in order to adapt to child's needs.The front end of guard bar 13 is articulated on the rocking arm, and insert in the guard bar sliding sleeve 14 on the handrail be fixed in vehicle frame seat 15 rear end.In rocking arm rocked back and forth process, can slide front and back in guard bar sliding sleeve 14 in the rear end of guard bar 13, thereby can not cause obstacle to shaking of rocking arm.
Embodiment 2:
As shown in Figure 2, the carriage for children in the present embodiment has vehicle frame 1, handlebar 2, front fork 3, front-wheel 4, trailing wheel 5, rocking arm 6, slip ring 7, universal-joint 8 and piston crank mechanism, and its body construction is similar to embodiment 1.Different is that the piston crank mechanism in the present embodiment has also been set up auxiliary montant 17 and auxiliary cross bar 18 except that having montant 9, cross bar 10 and crank 11, its objective is the lower length that reduces montant 9, drives perambulator not hinder the child with pin.
