Specific embodiment
The technical solution of the utility model is further elaborated in the following with reference to the drawings and specific embodiments.
Referring to Fig. 1 ~ kiddie car shown in Fig. 3, exist including vehicle frame 1, the seat mechanism being arranged on vehicle frame 19, setting
The front component of the bottom front of vehicle frame 1, the wheel assembly at bottom rear portion that vehicle frame 1 is set, the side for controlling kiddie car
To Direction Control Unit and footrest component 6.
Front component includes the near front wheel 21 and off-front wheel for being separately positioned on the left and right sides of bottom front of kiddie car
22, which further includes front axle 3, and the near front wheel 21 and off-front wheel 22 are rotatably arranged on front axle 3.Afterwards
Wheel assembly includes the rear-wheel 4 that the rear portion of kiddie car is arranged in, and rear-wheel 4 may be provided with one or two, after one or two
Wheel 4 is all made of universal wheel.
Direction Control Unit is rotatably arranged on vehicle frame 1, specifically, Direction Control Unit includes along the vertical direction
Extend and can be rotatably arranged at around self-axis line on vehicle frame 1 direction control lever 51, be fixed at direction control lever
The connector 53 of the steering wheel 52 of 51 upper end and the lower end for being fixed at direction control lever 51, footrest component 6 is with before
Wheel shaft 3 is rotatably arranged on connector 53.
Footrest component 6 includes the pedal spindle 61 being rotatably arranged on connector 53 and is fixed at pedal spindle 61
On foot pedal 62, in the present embodiment, pedal spindle 61 extends in left-right direction, and foot pedal 62 is separately positioned on a left side for pedal spindle 61
Right both ends.
A kind of specific embodiment, the front of vehicle frame 1 are provided with the casing 11 vertically extended, and casing 11 is set in
On direction control lever 51, direction control lever 51 can be rotationally arranged around self-axis line facing sleeve 11.
Another specific embodiment, connector 53 are equipped with the axle sleeve 531 extended in left-right direction, and pedal spindle 61 is worn
It can be arranged in axle sleeve 531 and rotationally around self-axis line with respect to axle sleeve 531.
Footrest component 6 is sequentially connected by transmission device 7 and front axle 3, can drive foot by foot-treadle 62 in this way
The rotation of axis 61 is stepped on, front axle 3 can be driven by transmission device 7 and rotate, so that the near front wheel 21 and off-front wheel 22 is driven to rotate, it is real
The traveling of existing kiddie car.
In the present embodiment, transmission device 7 uses chain and sprocket driving device, specifically, the chain and sprocket driving device include drive sprocket 71,
Driven sprocket 72 and the chain 73 being arranged on drive sprocket 71 and driven sprocket 72, drive sprocket 71 are set in pedal spindle 61
It above and with 61 phase of pedal spindle is fixedly connected, driven sprocket 72 is set on front axle 3 and is fixedly connected with 3 phase of front axle.
The kiddie car further includes being separately positioned between the near front wheel 21 and front axle 3, off-front wheel 22 and front axle 3
Unilateral bearing 8, unilateral bearing 8 include inner ring 81 and outer ring 82, and inner ring 81 is fixedly connected with 3 phase of front axle, outer ring 82 respectively with
The near front wheel 21 is fixedly connected with 22 phase of off-front wheel.By dividing between the near front wheel 21 and front axle 3, off-front wheel 22 and front axle 3
Not She Zhi unilateral bearing 8, kiddie car can be made when turning to, the revolving speed between 22 two wheels of the near front wheel 21 and off-front wheel is not
Together, and positioned at the revolving speed of a wheel of inside it is less than the revolving speed of a wheel positioned at outside, is i.e. is formed between two wheels
Differential facilitates the use of kiddie car, can also be achieved children so that the turning radius for turning to the kiddie car is smaller
The drift effect of bicycle improves the entertainment properties of the kiddie car.
Specifically, the inner ring 81 of unilateral bearing 8 is mutually fixedly connected with front axle 3 by interference fit.In unilateral bearing 8
Outer ring 82 is equipped with flange 821, which is mutually fixedly connected with the near front wheel 21 and off-front wheel 22 by bolt respectively.
When the kiddie car needs straight forward when driving, foot-treadle 62 makes pedal spindle 61 drive drive sprocket 71
It rotates counterclockwise, drives driven sprocket 72 and front axle 3 also to rotate counterclockwise by chain 73, at this point, unilateral bearing 8 is in lock
The rotation of dead state, the i.e. inner ring 81 of unilateral bearing 8 and 82 coaxial synchronous of outer ring, can drive a left side by unilateral bearing 8 in this way
Front-wheel 21 and off-front wheel 22 with front axle 3 synchronize rotate counterclockwise, in this way, the kiddie car can travel straight forward.
It when needing to turn to after kiddie car straight-line travelling a distance, such as turns to kiddie car to the left, stops
Foot pedal 62 is trampled, so that pedal spindle 61 and front axle 3 stop operating, at this point, unilateral bearing 8 is in inverted running state,
Its inner ring 81 follows front axle 3 to remain stationary, and due to the effect of inertia, it is inverse that outer ring 82 follows the near front wheel 21 and off-front wheel 22 to continue
Hour hands rotation；Steering wheel 52 is rotated counterclockwise while stopping and trampling foot pedal 62, direction control lever 51 is around self-axis line
Relative frame 1 rotates counterclockwise, inverse around the axial line relative frame 1 of direction control lever 51 with follower link 53 and front axle 3
Hour hands rotation, during the outer ring of unilateral bearing 8 82 follows the near front wheel 21 and off-front wheel 22 continues to rotate counterclockwise, due to position
The resistance that the off-front wheel 22 that the resistance ratios that the near front wheel 21 in inside is subject to are located at outside is subject to is big, this makes turning for the near front wheel 21
Speed is gradually lower than the revolving speed of off-front wheel 22, so that differential is formed between the near front wheel 21 and off-front wheel 22, to make children's foot
Turning radius when treadmill turns to the left is smaller.When the resistance that the near front wheel 21 for being located inside is subject to makes the near front wheel 21 stop operating
When, it so that the kiddie car is realized drift function, to improve the entertainment properties of the kiddie car.
It is similar with operation when turning to the left when needing to turn to the right after kiddie car straight-line travelling a distance, stop
Foot pedal 62 is only trampled, while rotating clockwise steering wheel 52, with follower link 53 and front axle 3 around direction control lever 51
Axial line relative frame 1 rotates clockwise, the outer ring of unilateral bearing 8 82 follow the near front wheel 21 and off-front wheel 22 by inertia after
Continue during rotating counterclockwise, what the near front wheel 21 that the resistance ratios that the off-front wheel 22 due to being located inside is subject to are located at outside was subject to
Resistance is big, this makes the revolving speed of off-front wheel 22 gradually be lower than the revolving speed of the near front wheel 21, thus the near front wheel 21 and off-front wheel 22 it
Between form differential, so that turning radius when turning to the kiddie car to the right is smaller.When be located inside off-front wheel 22 by
To resistance so that off-front wheel 22 is stopped operating when, can also make the kiddie car realize drift function, to improve children's foot
The entertainment properties of treadmill.
When the above-mentioned traveling about kiddie car, the definition of 22 rotation direction of the near front wheel 21 and off-front wheel, is according to people
It stands and defines from front to back in the front of kiddie car.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
