图4及图5为本实用新型的婴儿车架在展开及收合状态之枢接关节位置图。本实用新型的婴儿车架中，手轨40的后端枢接至车手10的中间处(D位置)及其前端枢接至前脚20的上端(B位置)，下杆50的前端枢接至前脚20的下端(A位置)，后脚30的上端枢接至前脚20设于中间处的枢接座21(C位置)。配合图7，连杆130的枢接孔133枢接至车手10的下端(F位置)，连杆130的枢接孔134枢接至下杆50设于中间处的枢接座54(G位置)，以及，连杆130的枢接孔135枢接至后脚30的中间处(E位置)。藉由上述构件相互间的枢接，促成本实用新型的婴儿车架可在展开状态与收合状态之间转换并自动锁定。当车架在使用状态时，第一凸台111与第一凹槽131卡合，而滑块120的下端122位于收合固定座140的孔141中。Fig. 4 and Fig. 5 are the positions of the pivotal joints of the stroller frame of the present invention in unfolded and folded states. In the baby carriage frame of the present utility model, the rear end of the hand rail 40 is pivotally connected to the middle of the rider 10 (position D) and its front end is pivotally connected to the upper end of the front leg 20 (position B), and the front end of the lower rod 50 is pivotally connected to The lower end of the front foot 20 (position A) and the upper end of the rear foot 30 are pivotally connected to the pivot seat 21 provided in the middle of the front foot 20 (position C). 7, the pivot hole 133 of the connecting rod 130 is pivotally connected to the lower end of the rider 10 (position F), and the pivot hole 134 of the connecting rod 130 is pivotally connected to the pivot seat 54 (position G) of the lower rod 50 in the middle. ), and the pivot hole 135 of the link 130 is pivotally connected to the middle of the rear foot 30 (position E). Through the pivotal connection between the above-mentioned components, the stroller frame of the present utility model can be switched between the unfolded state and the folded state and can be automatically locked. When the frame is in use, the first boss 111 engages with the first groove 131 , and the lower end 122 of the sliding block 120 is located in the hole 141 of the retractable fixing seat 140 .

在车架的收合过程中，如图1、2、8(a)及8(b)所示，首先，致动车手10上的收合机构60，以使钢线51朝着箭头X方向拉动滑块120(参照图2)，而滑块120同步带动滑套110沿着车手10向上方(X方向)移动，以使滑块120的下端122脱离收合固定座140的孔141(参照图6(a)及6(b))，而滑套110的第一凸台111也同时脱离连杆130的第一凹槽131(参照图7)，藉此使车架释锁，使车手10朝向手轨40及下杆50靠近，进而使车手10可沿着图8(a)中箭头B所示的方向转动。此时，连杆130的曲面136与滑套110的第二凸台112相接触滑动(如图8(a)所示)，进而使滑套110的第二凸台112落入连杆130的第二凹槽132(如图8(b)所示)，以使车架处于收合锁定状态。连杆130于滑套110的卡合，可以避免收合后婴儿车架意外展开，而维持收合状态。In the folding process of the vehicle frame, as shown in Figures 1, 2, 8(a) and 8(b), firstly, actuate the folding mechanism 60 on the driver 10 so that the steel wire 51 faces the direction of the arrow X Pull the slider 120 (refer to FIG. 2 ), and the slider 120 synchronously drives the sliding sleeve 110 to move upwards (X direction) along the driver 10, so that the lower end 122 of the slider 120 breaks away from the hole 141 of the retractable fixing seat 140 (refer to 6(a) and 6(b)), and the first boss 111 of the sliding sleeve 110 also breaks away from the first groove 131 of the connecting rod 130 (refer to FIG. 7 ) at the same time, thereby releasing the vehicle frame and allowing the rider to 10 approaches the hand rail 40 and the lower rod 50, so that the rider 10 can turn in the direction indicated by arrow B in FIG. 8(a). At this time, the curved surface 136 of the connecting rod 130 contacts and slides with the second boss 112 of the sliding sleeve 110 (as shown in FIG. The second groove 132 (as shown in FIG. 8( b )) enables the vehicle frame to be in a folded and locked state. The engagement of the connecting rod 130 with the sliding sleeve 110 can prevent the baby carriage frame from unfolding accidentally after being folded, and maintain the folded state.

图6至图8为为本实用新型的婴儿车架在展开状态与收合状态之间转换的过程图。在车架的展开过程中，首先，致动车手10上的收合机构60(参照图1)，以使钢线51朝着箭头X方向拉动滑块120(参照图2)，同时滑块110的第二凸台112脱离连杆130的第二凹槽132(参照图8(b))，藉此使车架释锁，进而使车手10沿着图6(b)中箭头A所示的方向转动。此时，滑块120的下端122及滑套110的第一凸台111分别在收合固定座140的斜面142上及连杆130的曲面136上之接触滑动作用下(如图6(b)所示，其中未显示第一凸台111)，当滑块120的下端122到达收合固定座140上方时，滑块120的下端122在弹簧52的弹力作用下落入收合固定座140的孔141内(如图6(a)所示)，而滑套110上的第一凸台111也同时落入连杆130的第一凹槽131内(如图7所示)，藉此使车手10固定位，以使车架处于展开锁定状态。FIG. 6 to FIG. 8 are diagrams showing the transition process of the stroller frame of the present invention between the unfolded state and the folded state. During the unfolding process of the vehicle frame, at first, actuate the folding mechanism 60 on the driver 10 (refer to FIG. 1 ), so that the steel wire 51 pulls the slider 120 (refer to FIG. 2 ) toward the arrow X direction, and the slider 110 The second boss 112 of the connecting rod 130 disengages from the second groove 132 (refer to FIG. 8(b)), thereby releasing the frame, and then allowing the driver 10 to move along the direction indicated by arrow A in FIG. 6(b). direction to turn. At this time, the lower end 122 of the slider 120 and the first boss 111 of the sliding sleeve 110 are respectively under the action of contact and sliding on the inclined surface 142 of the retractable fixing seat 140 and the curved surface 136 of the connecting rod 130 (as shown in Figure 6(b) As shown, wherein the first boss 111 is not shown), when the lower end 122 of the slider 120 reaches the top of the folding fixing seat 140, the lower end 122 of the sliding block 120 falls into the hole of the folding fixing seat 140 under the elastic force of the spring 52 141 (as shown in Figure 6(a)), and the first boss 111 on the sliding sleeve 110 also falls into the first groove 131 of the connecting rod 130 at the same time (as shown in Figure 7), so that the driver 10 fixed positions, so that the frame is in the unfolded and locked state.

后脚30的前段可连接座板70或座布，而下杆50则可连接菜篮(未显示)。The front section of the rear foot 30 can be connected to the seat plate 70 or seat cloth, and the lower rod 50 can be connected to a vegetable basket (not shown).

惟以上所述者，仅为本实用新型之较佳实施例而已，当不能以此限定本实用新型实施之范围，即大凡依本实用新型申请专利范围及实用新型说明书内容所作之简单的等效变化与修饰，皆应仍属本实用新型专利涵盖之范围内。But the above is only a preferred embodiment of the utility model, and should not limit the scope of the utility model implementation with this, that is, all simple equivalents made according to the scope of the utility model patent application and the content of the utility model description Changes and modifications should still fall within the scope covered by the utility model patent.
