The seat bidirectional folding structure provided by the invention is suitable for infant carriers such as high-leg chairs for children, infant strollers and the like. As shown in fig. 1-5, it can be understood that the infant carrier includes a front foot joint 110 disposed at an upper end of a front foot frame 100, a rear foot joint 210 disposed at an upper end of a rear foot frame 200, and a seat support joint 310 for supporting a carrying portion, wherein the front foot joint 110 and the rear foot joint 210 are rotatably connected along a rotation axis, the seat support joint 310 can rotate relative to the front foot joint 110 and the rear foot joint 210, and the seat support joint 310 protrudes towards two sides to form a first support portion 311 and a second support portion 312 respectively; the forefoot joint 110 is provided with a first support 113 in a direction parallel to the rotation axis toward one side of the front foot stool 100, and a second support 213 in a direction parallel to the rotation axis toward one side of the rear foot stool 200 of the rear foot joint 210; when the front foot joint 110 and the rear foot joint 210 rotate to the state that the infant carrier is folded, the first supporting part 113 and the second supporting part 213 are close to each other, and the seat supporting joint 310 can rotate forwards relative to the front foot joint 110 and the rear foot joint 210 to realize forward folding or rotate backwards to realize backward folding; when the front foot joint 110 and the rear foot joint 210 rotate to the state that the infant carrier is in the open state, the first supporting portion 113 and the second supporting portion 213 are far away, the first supporting portion 311 abuts against the first supporting portion 113, and the second supporting portion 312 abuts against the second supporting portion 213, so as to position the seat supporting joint 310. As shown in connection with fig. 6-7, more specifically:
preferably, as shown in fig. 3-6, the forefoot joint 110 and the rearfoot joint 210 are rotatably coupled along a rotational axis; the front leg joint 110 has a first sliding slot 112, and the rear leg joint 210 has a second sliding slot 212. The first runner 112 and the second runner 212 have an overlapping area in a plane perpendicular to the axis of rotation; a connecting pin 313 is fixedly connected to one side of the seat support joint 310 facing the forefoot joint 110 and the rearfoot joint 210, and the connecting pin 313 is inserted into the first sliding groove 112 and the second sliding groove 212, so that the seat support joint 310 is connected to the forefoot joint 110 and the rearfoot joint 210. In the preferred embodiment, the overlapping area of the first sliding slot 112 and the second sliding slot 212 changes with the rotation of the front foot joint 110 and the rear foot joint 210, and the connecting pin 313 inserted into the first sliding slot 112 and the second sliding slot 212 locks or unlocks the relative rotation of the front foot joint 110 and the rear foot joint 210 while realizing the rotatable connection of the seat supporting joint 310 with the front foot joint 110 and the rear foot joint 210.
In one embodiment shown in fig. 4a and 4 b: the first chute 112 and the second chute 213 are both arc-shaped with the rotation axis as the center; when the front foot joint 110 and the rear foot joint 210 rotate to the state that the infant carrier is in the opening state, the overlapping area of the first sliding groove 112 and the second sliding groove 213 is reduced, the connecting pin 313 is limited by the first sliding groove 112 and the second sliding groove 213, and the connecting pin 313 limits the front foot joint 110 and the rear foot joint 210 to be locked and further opened, so that the infant carrier is kept in the preset opening state; when the front foot joint 110 and the rear foot joint 210 rotate to the state that the infant carrier is folded, the overlapping area of the first sliding groove 112 and the second sliding groove 213 is enlarged, and the connecting pin 313 can slide in the overlapping area; in this embodiment, when the infant carrier is folded, the position of the seat supporting joint 310 is changed along with the sliding of the connecting pin 313 in the first sliding slot 112 and the second sliding slot 213, so as to facilitate folding.
Further, as shown in fig. 4a to 6, the cross section of the connecting pin 313 is non-perfect circular, and the width of a partial area of the cross section of the connecting pin 313 is greater than the width of the first runner 112 or the second runner 212; according to this structure, the connecting pin 313 is not rotatable relative to the first and second sliding grooves 112 and 212. When the front foot joint 110 and the rear foot joint 210 rotate to the folded state of the infant carrier and the overlapping area of the first sliding chute 112 and the second sliding chute 212 is increased, the connecting pin 313 can slide in the overlapping area, so that the seat supporting joint 310 can rotate forwards or backwards relative to the front foot joint 110 and the rear foot joint 210 to fold; when the front foot joint 110 and the rear foot joint 210 rotate to the state that the infant carrier is in the open state and the overlapping area of the first sliding chute 112 and the second sliding chute 212 is reduced, the connecting pin 313 is limited by the first sliding chute 112 and the second sliding chute 212, and meanwhile, the connecting pin 313 also limits the further open of the front foot joint 110 and the rear foot joint 210, and at this time, the connecting pin 313 can play a role in auxiliary limiting for the seat support joint 310.
In another embodiment shown in fig. 7 a-7 c: the first runner 112 and the second runner 212 are linear, and the diameter of the cross section of the connecting pin 313 is smaller than or equal to the width of the first runner 112 and the second runner 212; the connecting pin 313 can rotate in the first sliding slot 112 and the second sliding slot 212 to fold the seat support joint 310 by rotating forward or backward relative to the forefoot joint 110 and the rearfoot joint 210. In this embodiment, the seat support joint 310 is not restricted from rotating even when the infant carrier is in the open state.
In other embodiments different from the two embodiments, the first sliding groove 112 and the second sliding groove 212 may also be arc-shaped or have other shapes.
As shown in fig. 2, 6 and 7: a first support part 113 is provided on the side of the forefoot joint 110 facing the front foot rest 100 in a direction parallel to the rotation axis, and a second support part 213 is provided on the side of the rearfoot joint 210 facing the rear foot rest 200 in a direction parallel to the rotation axis. When the front foot joint 110 and the rear foot joint 210 rotate to the state that the infant carrier is in the open state, the first supporting part 113 and the second supporting part 213 are far away from each other; when the front foot joint 110 and the rear foot joint 210 rotate until the infant carrier is in the folded state, the first supporting part 113 and the second supporting part 213 approach each other. The seat support joint 310 is formed with a first support arm 311 and a second support arm 312 protruding towards two sides, and when the front leg joint 110 and the rear leg joint 210 rotate to the state that the infant carrier is in the open state, the first support arm 311 abuts against the first support part 113, and the second support arm 312 abuts against the second support part 213.
It will be appreciated that the first support 113 and the second support 213 are disposed in the path of rotation of the seat support joint 310 relative to the forefoot joint 110 and the rearfoot joint 210. When the infant carrier is in the unfolded state, the front foot joint 110 and the rear foot joint 210 are unfolded, the first supporting part 113 and the second supporting part 213 are far away, the first supporting part 311 abuts against the first supporting part 113, and the second supporting arm 312 abuts against the second supporting part 213, so that the rotation of the seat supporting joint 310 relative to the front foot joint 110 and the rear foot joint 210 is limited, and the reliable limit of the seat supporting joint 310 is realized. When the infant carrier is in the folded state, the front foot joint 110 and the rear foot joint 210 are folded, and the first supporting portion 113 and the second supporting portion 213 are close to each other, and at this time, the seat supporting joint 310 can rotate relative to the front foot joint 110 and the rear foot joint 210 to realize forward folding or backward folding.
Specifically, as shown in fig. 2 and 3, in the present embodiment, the first supporting portion 113 and the second supporting portion 213 are respectively in a tubular structure, and in other embodiments different from the present embodiment, the first supporting portion 113 and the second supporting portion 213 may also be in a long rod shape. The first support arm 311 and the second support arm 312 are respectively bent towards the first support part 113 and the second support part 213, so that when the front foot joint 110 and the rear foot joint 210 rotate to the infant carrier in the open state, the first support arm 311 and the second support arm 312 correspondingly clamp the first support part 113 and the second support part 213.
