Detailed description of the invention
as shown in Figures 1 to 6, a kind of children trolley of the present invention, comprises the vehicle frame with deployed condition and folded state, the front-wheel 7 being arranged on vehicle frame lower front portion, the trailing wheel 8 being arranged on vehicle frame lower rear and the blocking device for vehicle frame being locked in expansion/folded state.Described vehicle frame comprises front-wheel support 1, rear wheel support 2 and push rod 3.Described front-wheel 7 is arranged on the bottom of front-wheel support 1, and described trailing wheel 8 is arranged on the bottom of rear wheel support 2.
described front-wheel support 1 comprises the front-wheel pole 5 that bottom is connected with front-wheel 7 and the connecting rod 6 being fixedly installed on front-wheel pole 5 top, and described connecting rod 6 intersects vertically with front-wheel pole 5.In the present embodiment, connecting rod 6 is weldingly fixed on front-wheel pole 5.Described connecting rod 6 is connected by the first sliding sleeve 4 with rear wheel support 2, and described first sliding sleeve 4 rotates and is arranged on the end of connecting rod 6 away from front-wheel pole 5.Described rear wheel support 2 is located in the first sliding sleeve 4 and also can slides in the first sliding sleeve 4.Described push rod 3 is slidably arranged on front-wheel support 1, and the bottom of described push rod 3 and the upper end of rear wheel support 2 are rotationally connected by pin.The upper end of described front-wheel pole 5 is fixedly equiped with the second sliding sleeve 9, and described push rod 3 is located in the second sliding sleeve 9 slidably.The junction of described push rod 3 and rear wheel support 2 is lower than the position at the second sliding sleeve 9 place.Described front-wheel support 1, rear wheel support 2, push rod 3 and the first sliding sleeve 4 form slider-crank mechanism.
when vehicle frame is in deployed condition, front-wheel support 1 and rear wheel support 2 support vertical mutually, and described push rod 3 stretches towards the direction away from front-wheel 7; When vehicle frame is in folded state, described front-wheel support 1 is drawn close mutually with rear wheel support 2, and described push rod 3 shrinks towards near the direction of front-wheel 7.
when blocking device unlocks, described push rod 3 can slide along the bearing of trend of front-wheel pole 5.Described push rod 3 slides and drives rear wheel support 2 to move, and when described push rod 3 slides towards near the direction of front-wheel 7, the upper end of described rear wheel support 2 is drawn close towards front-wheel 7 direction; When described push rod 3 slides towards the direction away from front-wheel 7, the upper end of described rear wheel support 2 is pulled up towards moving away from front-wheel 7 direction.
when the children trolley of deployed condition is folded, first blocking device is unlocked, then push rod 3 is promoted to front-wheel 7 direction, push rod 3 is slide downward in the second sliding sleeve 9, described front-wheel support 1, rear wheel support 2, push rod 3 and the first sliding sleeve 4 form slider-crank mechanism running, and rear wheel support 2 is drawn close to front-wheel under the drive of push rod 3, and the angle between rear wheel support 2 and push rod 2 diminishes gradually, push rod 3, front-wheel support 1 have so far folded together with mutually drawing close with rear wheel support 2.
when being launched by the children trolley of folded state, the motion of whole vehicle frame is with contrary time folding.First upwards lifted by push rod 3, push rod 3 is along the bearing of trend upward sliding of front-wheel pole 5, and rear wheel support 2 is also upwards pulled up under the drive of push rod 3, and the angle between push rod 3 and rear wheel support 2 increases to gradually and launches completely.
from above-mentioned, the vehicle frame parts of children trolley of the present invention only have limited several such as front-wheel support 1, rear wheel support 2, push rod 3, first sliding sleeve 4, second sliding sleeve 9, and vehicle frame is succinct, and structure is simple, with low cost.And folding step is simple, can a step be folding puts in place, convenient and easy.After folding, because parts are less, mutually draw close compact after folding, take up room little, be easy to carry.
as mentioned above, we are illustrated according to aim of the present invention completely, but the present invention is not limited to above-described embodiment and implementation method.Different changes and enforcement is carried out in the scope that the practitioner of correlative technology field can permit at technological thought of the present invention.
