The invention discloses a joint structure which comprises a front supporting rod connected with a front hinge seat, a rear supporting rod connected with a rear hinge seat and an upper supporting rod connected with an upper hinge seat, the rear hinge seat and the upper hinge seat are rotatably connected around a first axis, and the rear hinge seat and the front hinge seat are rotatably connected around a second axis parallel to the first axis. A linkage structure is arranged between the upper hinge seat and the front hinge seat, can drive the front hinge seat to drive the front supporting rod to rotate around the second axis to get close to the rear supporting rod when the upper hinge seat and the upper supporting rod rotate around the first axis to get close to the rear supporting rod, and comprises a matching wall arranged on the front hinge seat. The upper hinge seat is provided with a pushing part which can slide along the matching wall and push the matching wall to enable the front hinge seat to rotate around the second axis when the upper hinge seat rotates around the first axis. The invention further discloses a baby carrier adopting the joint structure. The joint structure and the baby carrier are simple in structure, low in cost and small in size after being folded.

    本发明公开了一种关节结构,包括连接有前铰接座的前支杆、连接有后铰接座的后支杆和连接有上铰接座的上支杆,后铰接座与上铰接座绕第一轴线可转动连接,后铰接座与前铰接座绕与第一轴线平行的第二轴线可转动连接,并且上铰接座与前铰接座之间设有在上铰接座和上支杆绕第一轴线向后支杆转动靠拢时能够驱动前铰接座带着前支杆绕第二轴线向后支杆转动靠拢的联动结构,联动结构包括设在前铰接座上的配合壁,上铰接座上设有在其绕第一轴线转动时能沿配合壁滑动并顶推配合壁而使前铰接座绕第二轴线转动的推动部。本发明还公开一种采用前述关节结构的童车。本发明关节结构及童车结构简单,成本低廉,折叠后体积小。
