Abstract
The invention discloses a baby stroller which comprises a stroller frame and a front wheel assembly arranged at the front portion of the stroller frame. The front wheel assembly comprises front wheel joints connected with the stroller frame and front wheels capable of being rotationally arranged on the front wheel joints. The baby stroller further comprises idler wheels which can be rotationally arranged on the front wheel joints through idler wheel shafts. The front edges of the idler wheels are located in front of the front edges of the front wheels. The lower edges of the idler wheels are located above the lower edges of the front wheels. When the baby stroller encounters an obstacle on the ground, the idler wheels make contact with the obstacle, the idler wheels rotate around the idler wheel shafts to drive the front wheels to ascend, and therefore the front wheels cross the obstacle. The baby stroller is simple in structure, when the baby stroller encounters the obstacle in the moving process, a push handle does not need to be pressed down, the front wheels can cross the obstacle simply by normal pushing, time and labor are saved, and the baby stroller is used quite conveniently.

Preferably, described roller can be slidably arranged on described front-wheel joint, and when described children trolley runs into the barrier on ground, described roller and bar contact make described roller upward sliding on described front-wheel joint.
Further, described front-wheel joint is provided with and tilts the chute extended from front to back from bottom to top, and described roller shaft is located in described chute and can slide in described chute along the bearing of trend of described chute.
Yet further, when described children trolley is when smooth road traveling, described roller shaft is positioned at the bottom of described chute.
Yet further, described children trolley is additionally included in after described front-wheel clears the jumps for ordering about the reset element that described roller shaft resets.
Further, described reset element adopts stage clip, described stage clip is arranged in described chute and is positioned at the top of described roller shaft, described children trolley also includes to be slidably arranged in the slide block in described chute along the bearing of trend of described chute, described roller shaft is fixedly installed on described slide block, the one end of described stage clip is connected with described slide block, and the other end of described stage clip is connected with described front-wheel joint.
Further, the telescopic direction of described stage clip is identical with the bearing of trend of described chute.
Preferably, the distance between described roller lower limb and described front-wheel lower limb is not more than 1/4th of described front wheel diameter.
Preferably, the front-wheel of the every side of described children trolley includes two wheels, and described roller is between two described wheels.
Utilization due to technique scheme, the present invention compared with prior art has the advantage that the children trolley simple in construction of the present invention, when children trolley traveling process is encountered barrier without under press handle, normal carrying out can make front-wheel clear the jumps, time saving and energy saving, very easy to use.
Accompanying drawing explanation
Accompanying drawing 1 is one of structural representation of children trolley of the present invention；
Accompanying drawing 2 is the two of the structural representation of the children trolley of the present invention；
Accompanying drawing 3 is A place partial enlarged drawing (removing front-wheel) in accompanying drawing 1；
Accompanying drawing 4 is A place phantom (enlarged drawing removes front-wheel) in accompanying drawing 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical scheme is further elaborated.
As shown in Fig. 1 ~ Fig. 4, the children trolley of the present invention includes stroller frame and the front component of the front portion, the end being arranged on stroller frame, front component includes front-wheel joint 1, front-wheel 2 and roller 3, front-wheel joint 1 is connected with stroller frame, front-wheel 2 can be rotatably arranged on front-wheel joint 1, and roller 3 can be rotatably arranged on front-wheel joint 1.
The leading edge of roller 3 is positioned at the front of the leading edge of front-wheel 2, the lower limb of roller 3 is positioned at the top of the lower limb of front-wheel 2, and the distance between the lower limb of the lower limb of roller 3 and front-wheel 2 be not more than front-wheel 2 diameter 1/4th, when children trolley runs into the barrier on ground, roller 3 first with bar contact, roller 3 is rotated, and orders about front-wheel 2 and raise so that front-wheel 2 clears the jumps.For making front-wheel to clear the jumps more easily, or cross of a relatively high barrier, roller 3 can be slidably arranged on front-wheel joint 1, now, when children trolley runs into barrier, roller 3 simultaneously opposing front wheels joint 1 upward sliding in the process rotated, so that front-wheel 2 can raise further and more convenient clear the jumps.
A kind of specific embodiment, front-wheel joint 1 is provided with chute 11, roller 3 is rotatably arranged on front-wheel joint 1 by roller shaft 4, chute 11 tilts to extend from bottom to top from front to back on front-wheel joint 1, roller shaft 4 is located in chute 11 and can slide along the bearing of trend of chute 11, when children trolley travels on smooth road surface, roller shaft 4 is positioned at the bottom of chute 11.When children trolley encounters barrier in traveling process, still normally carry out children trolley, first such roller 3 is against on barrier, the active force of the normal child of carrying out makes roller 3 roll along barrier after being delivered on roller 3, order about roller shaft 4 upward sliding in chute 11 simultaneously, front-wheel 2 is so made to raise, raising at front-wheel 2 to a certain degree to make front-wheel 2 clear the jumps afterwards, such mode crossing barrier of the front-wheel 2 of children trolley, do not need down to press the handle of children trolley, time saving and energy saving, very easy to use.
This children trolley is additionally included in the reset element 5 after the front-wheel 2 of children trolley clears the jumps for making roller shaft 4 reset, in the present embodiment, reset element 5 adopts stage clip, this stage clip is also disposed in chute 11 and is positioned at the top of roller shaft 4, the telescopic direction of stage clip is identical with the bearing of trend of chute 11, this children trolley also includes the slide block 6 that can be slidably arranged in chute 11, roller shaft 4 is fixing with slide block 6 to be connected, the one end of stage clip is fixedly connected on slide block 6, and the other end is fixedly connected on front-wheel joint 1.When in the process that children trolley clears the jumps in traveling process, roller shaft 4 makes stage clip be compressed in chute 11 during upward sliding, after front-wheel 2 clears the jumps, the power on roller 3 that acts on disappears, and roller shaft 4 resets along chute 11 slide downward under the effect of the elastic force of stage clip.It addition, by the impact arranging the front-wheel 2 that can also the reduce children trolley produced impact endurance test shock in the process the cleared the jumps child on resting in children trolley of stage clip.
A kind of specific embodiment, the front-wheel 2 of every side of this children trolley includes two wheels, and roller 3 is between two wheels, when roller 3 is positioned at middle position the best of two wheels.
In sum, the children trolley simple in construction of the present invention, when children trolley traveling process is encountered barrier without under press handle, normal carrying out can make front-wheel clear the jumps, time saving and energy saving, very easy to use；And this children trolley also can reduce the impact of the produced impact endurance test shock child on resting in children trolley when front-wheel clears the jumps.
Above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this.All equivalences made according to spirit of the invention change or modify, and all should be encompassed within protection scope of the present invention.
