Technical field

The utility model relates to perambulator bearing circle ripple case, the dual-purpose ripple case of especially a kind of perambulator bearing circle.

Background technology

Perambulator is a kind ofly for play a kind of rolling cart of usefulness of children various vehicles to be arranged, and generally is the toy car that belt wheel is arranged, and perambulator bring certain benefit can for child's intelligence development, and the brains that increases child is grown.In perambulator commonly used at present, be that direction of passage dish or remote controller are controlled to change the direction of traffic of perambulator the front-wheel direction.

As, a kind of steering hardware of perambulator is disclosed in Chinese patent ZL200920180342, comprise bearing circle, rotating shaft, front fork, wheel flutter, described bearing circle is captiveed joint with described upward rotating shaft, the axle of described front fork and wheel flutter is connected, and is connected by rigid cardan between described rotating shaft and the described front fork; During operation, the hand of rotation dish drives connected rotating shaft and rotates, and by described rigid cardan the button square passed to front fork, and front fork is rotated, and drives the wheel flutter rotation that is attached thereto, thereby realizes turning to of vehicle body.Though the steering hardware of this perambulator is simple in structure, the bearing circle anglec of rotation is little, the rotation great efforts, and it is out of control to cause operator's dispersion attention to be turned round, and the child that strength is little is revolved motionless at all.

And for example, the steering apparatus that discloses a kind of remote control electric perambulator in Chinese patent ZL200520053480 comprises bearing circle, the steering box of deflecting bar and drive deflecting bar, but at the steering controller that is provided with its turning of M/C when telecar is kept straight between bearing circle and the deflecting bar, the control lid that described steering controller comprises control seat and socket-connects with it, wherein: described control seat is connected with deflecting bar, described control lid is connected with bearing circle and deflecting bar respectively, transmission device work and drive the steering hardware that perambulator is turned in the automatically starting steering box when being provided with when steering wheel rotation between control lid and the control seat.The bearing circle of this perambulator is rotatable less than wide-angle and required dynamics, but its complex structure, operates loaded down with trivial detailsly, and gear transmission exposes influence stability such as easy drop grain, is easy to generate potential safety hazard.

Summary of the invention

At the shortcoming of prior art, the purpose of this utility model provides the dual-purpose ripple case of a kind of perambulator bearing circle, and it is simple in structure, safe and reliable, but and the bearing circle easy manipulation revolve three-sixth turn.

To achieve these goals, the technical solution of the utility model is: the dual-purpose ripple case of a kind of perambulator bearing circle, comprise manual speed reduction gearing, telemotor speed reduction gearing and output mechanism, output mechanism respectively with manual speed reduction gearing, the telemotor speed reduction gearing connects, wherein, manually speed reduction gearing comprises S. A., swing pinion, transmission gear, inner gear and gear frame, captive joint with bearing circle in the S. A. upper end, captive joint with swing pinion in the lower end, swing pinion and transmission gear are connected with a joggle, transmission gear and inner gear are connected with a joggle, inner gear and gear frame are fixedly connected to form housing with swing pinion, in transmission gear was encapsulated in, gear frame was connected with output mechanism.

Described telemotor speed reduction gearing comprises ripple case upper casing, first reducing gear, second reducing gear, the 3rd reducing gear, motor gear and ripple case lower casing, first reducing gear, second reducing gear, the 3rd reducing gear, motor gear is arranged in the casing that ripple case upper casing and ripple case lower casing be combined into, the turning cylinder of telemotor is connected with motor gear, motor gear and the 3rd reducing gear are connected with a joggle, the deceleration axle center fulcrum and second reducing gear on the 3rd reducing gear are connected with a joggle, the deceleration axle center fulcrum and first reducing gear on second reducing gear are connected with a joggle, and first reducing gear is connected with output mechanism.

Described output mechanism is a shared lever, described gear frame overlays on the described ripple case upper casing, be respectively equipped with draw-in groove on gear frame, described first reducing gear, gear frame, first reducing gear are blocked the barrel bolt on the shared lever by draw-in groove respectively and are captiveed joint with shared lever.

Compared with prior art, the number of turns of S. A. of the present utility model rotation is many and the number of turns shared lever rotation is few, thereby reaches the deceleration purpose, revolves three-sixth turn but make with S. A. bonded assembly bearing circle easy manipulation.
