[0051] Further, the door extension section 52 and the door body section 51 are integrally formed, and the door body 5 further has an arc-shaped connecting section connecting between the door extension section 52 and the door body section 51. That is, the door body 5 is a whole part, and the size of the arc-shaped connecting section is determined according to the included angle between the door extension section 52 and the door body section 51. The arc-shaped transition makes the connection in two directions smoother, and the part of the arc-shaped connecting section protruding outward can also increase the carrying space.

[0052] Please refer to Figures 1 to 3The carrier further comprises a seat 2, the seat 2 comprising a seat plate 21 and a back plate 22 arranged on the seat plate 21, the carrying space having a first side and a second side arranged opposite in the front-rear direction; the seat 2 is detachably installed on the carrying seat 1 in a forward attitude and a reverse attitude, in the forward attitude, the seat plate 21 is located close to the first side of the carrying space relative to the back plate 22, in the reverse attitude, the seat plate 21 is located close to the second side of the carrying space relative to the back plate 22; the back plate 22 has a folded state of being folded to be close to the seat plate 21 and an unfolded state of being unfolded to form an angle with the seat plate 21, in the forward attitude and the reverse attitude, the back plate 22 can be folded; in the unfolded state, the seat plate 21 can be used for a child to sit, and the back plate 22 provides support for the upper body of the child, and in the folded state, the back plate 22 is attached to the seat plate 21, facilitating storage.

[0053] Specifically, when the recessed area is arranged on the carrying seat 1, in the folded state, the back plate 22 is folded to the recessed area 11, and the side of the back plate 22 away from the seat plate 21 together with the carrying area 12 forms a combined carrying surface for lying, for the child to lie flat. The recessed area 11 is located close to the front frame body 6 of the carrying seat 1. Thus, the carrier can provide both seating function and lying board function, and the combined form is variable, more flexible, and suitable for different use requirements.

[0054] It should be noted that the seat 2 is a structure with seating function, and the combination of the seat plate 21 and the back plate 22 can form the structure of a seat pocket, that is, the seat plate 21 has a certain curvature and can be adapted to the hips of a child, thereby providing a comfortable experience for the child to sit.

[0055] Further, in the unfolded state, the carrier can simultaneously seat two children, one on the seat and the other on the carrying seat, and in the forward and reverse attitudes, the two children can sit in the same direction or opposite directions.

[0056] Specifically, when the door body is in the open state, a larger seating space can be provided for the child, so that the back plate 22 and the door body segment have sufficient space in the up-down direction, avoiding the head of the child from being pressed against the door body, and providing sufficient space for the legs and hands of the child.

[0057] In the embodiment, the carrying seat 1 is formed with a recessed area 11 and a carrying area 12; in the folded state, the back plate 22 is folded to the recessed area 11, and the side of the back plate 22 away from the seat plate 21 together with the carrying area 12 forms a combined carrying surface for lying. Thus, the seat 2 has two installation states when installed in the forward attitude or the reverse attitude, the combined form is variable, more flexible, and suitable for different use requirements.

[0058] The recessed area 11 and the bearing area 12 are both corresponding parts on the bearing seat 1, and the sizes of the two can be the same or different, the size of the recessed area 11 should be considered the design size of the back plate 22 when designing, and the depth of the recessed area 11 also needs to adapt to the thickness of the seat 2 in the folded state, so as to avoid the height difference between the outer side of the back plate 22 and the bearing area 12 when the seat 2 is in the folded state.

[0059] It should be understood that the seat plate 21 and the back plate 22 can be rotationally matched, in the unfolded state, the seat plate 21 and the back plate 22 should be able to be fixed at a set angle, the included angle between the planes where the seat plate 21 and the back plate 22 are located is an obtuse angle; in the unfolded state, the seat plate 21 and the back plate 22 should be able to be fixed in a certain posture, that is, they are attached, so that the back plate 22 will not be suddenly turned over during cooperation with the bearing area 12, thereby ensuring that children can safely lie on the combined bearing surface without worrying that the back plate 22 will suddenly change state due to external force. Based on this requirement, a lock catch structure should be provided on the seat 2, which needs to be able to lock the seat plate 21 and the back plate 22 in the folded state or the unfolded state, so that the angle of the seat plate 21 and the back plate 22 is fixed, and also can be unlocked to enable the seat plate 21 and the back plate 22 to rotate relative to each other.

[0060] The utility model does not limit the form of the lock catch structure, which only needs to have the functions of unlocking and locking.

[0061] Due to the size setting of the recessed area 11 and the size cooperation of the back plate, when the seat 2 is installed in the forward direction and the reverse direction, there can be a case where the back plate 22 is in the folded state and the edge of the back plate 22 seamlessly connects with the edge of the recessed area 11, or there can be a case where the edge of the back plate 22 is spaced apart from the edge of the recessed area 11.

[0062] In some embodiments, the recessed area 11 includes a first groove body 111, a second groove body 112 and a support boss separating the first groove body 111 and the second groove body 112, which are arranged in the front-rear direction, wherein the second groove body 112 is located beside the bearing area 12, in the unfolded state, the seat plate 2 is supported on the support boss, and the first groove body 111 and the second groove body 112 are respectively used for placing the feet of children in the forward posture and the reverse posture, so that the recessed area 11 forms an accommodation space in both the forward posture and the reverse posture of the seat 2, so that the feet of children have a placing space when sitting on the seat 2 in different directions, thereby providing a comfortable riding experience for children.

[0063] The carrier can accommodate two children, in some embodiments, the size of the second groove 112 is larger than the size of the first groove 111, when installed in the forward position, the seat plate 2 covers part of the second groove 112, and the first groove 111 is exposed outward, at this time, the first groove 111 forms a space for the child on the seat 2 to place his feet, and the other child sits in the carrying area 12, both children face forward. When installed in the reverse position, the seat plate covers the first groove 111, at this time, the other child sits in the carrying area 12, and the two children sit facing each other. By setting the size of the second groove 112 larger, the second groove 112 can accommodate the feet of two children at the same time.

[0064] It should be understood that the bottom wall surface of the first groove 111 and / or the second groove 112 can be through, at this time, the child's feet can be suspended when sitting.

[0065] In order to facilitate the quick disassembly and attitude adjustment of the seat, the carrying seat and the seat are provided with a mounting part and a cooperating part respectively, and the cooperating part is detachably connected with the mounting part. For example, a mounting part 13 can be provided at the middle position of the recessed area 11, and a cooperating part 23 is correspondingly provided on the seat plate 21. The shape and structure of the cooperating part 23 and the mounting part 13 are arranged to allow the cooperating part 23 to be connected and cooperated with the mounting part 13 in both forward and reverse directions. In this way, when converting the seat 2 from the forward position to the reverse position, only the seat 2 needs to be lifted to separate the mounting part 13 and the cooperating part 23, and then the direction of the seat 2 can be changed manually.

[0066] Furthermore, the carrying seat 1 also has a support structure for supporting the seat plate 21 in the folded state; in the folded state, the support structure supports the end of the seat plate 21 away from the back plate 22; the support structure includes a protrusion provided on the inner wall of the recessed area 11; the support structure is provided with two, which are arranged in the front-rear direction to support the seat plate 21 in the forward position and the reverse position respectively. Thus, the seat 2 has good load-bearing effect.

[0067] In other embodiments, please refer to Figure 3 , the seat 2 also includes a rotating support shaft 24, and the seat plate 21 and the back plate 22 are rotatably connected with the rotating support shaft 24; the rotating support shaft 24 is provided with a cooperating part 23. Since the distance between the rotating support shaft 24 and the edge of the recessed area 11 changes when the direction of the seat 2 is changed, the size of the recessed area 11 needs to be reasonably set so that the distance between the mounting part 13 and the two ends of the recessed area 11 in the front-rear direction can accommodate the size of the seat plate 21 and the back plate 22.

[0068] It should be understood that the mounting portion 13 can be arranged at the bottom of the recessed area 11 or at the side of the recessed area 11, and in an embodiment, the fitting portion 23 is arranged at the side end of the seat 2, and the mounting portion 13 is arranged at the side wall of the recessed area 11.

[0069] Specifically, the utility model is not limited to the structure of the fitting portion 23 and the mounting portion 13, and in some embodiments, one of the fitting portion 23 and the mounting portion 13 is arranged as a limiting groove, and the other is arranged as a limiting protrusion. Considering the functions of the limiting groove and the limiting protrusion, the limiting groove can be arranged as a T-shaped groove, a dovetail groove or other structure that can simultaneously play the roles of insertion and anti-disengagement, and the limiting protrusion is matched with the shape of the limiting groove. In this embodiment, since the mounting portion 13 is arranged at the side of the recessed area 11, the fitting direction of the limiting groove and the limiting protrusion is upward and downward, that is, the limiting groove is at least open at the upper end, so that the limiting protrusion can be inserted and pulled in the upward and downward direction, and in this embodiment, the upper end and the side end of the limiting groove are both arranged as open.

[0070] In other embodiments, one of the fitting portion 23 and the mounting portion 13 is arranged as a buckle, and the other is arranged as a clamping groove, so as to realize installation and limiting through elastic clamping

[0071] When the mounting portion 13 and the fitting portion 23 are fitted laterally, considering the stability of the seat 2 after installation, a supporting fitting structure can be arranged at the opposite side of the mounting portion 13, so as to balance the force when the mounting portion 13 and the fitting portion 23 are connected. Alternatively, two mounting portions 13 and two fitting portions 23 can be arranged correspondingly, so as to balance the force.

[0072] In some embodiments, the mounting portion 13 is arranged at least two along the front and back direction; in the forward posture, the fitting portion 23 is connected with the mounting portion 13 close to the bearing area 12; and in the reverse posture, the fitting portion 23 is connected with the mounting portion 13 away from the bearing area 12. At this time, the fitting portion 23 can be fitted with any one of the mounting portions 13, and when the forward posture and the reverse posture of the seat 2 are converted, the seat 2 needs to be lifted to separate the current mounting portion 13 and the fitting portion 23, and then the direction of the seat 2 is changed artificially, and the fitting portion 23 is connected with the other mounting portion 13, so as to realize the conversion of the direction.

[0073] In the embodiment, the two mounting portions 13 are arranged on the side walls of the recessed area 11 and are spaced apart in the front-rear direction. In one way, the two mounting portions 13 are arranged on the same side wall of the recessed area 11, and the matching portion 23 is arranged on the side of the seat 2, and the adjustment of the forward and reverse attitudes is realized by changing the connection of the mounting portions 13 and the mounting direction, and at this time, the support of the seat 2 needs to be considered; in another way, the two mounting portions 13 are arranged on the opposite side walls of the recessed area 11, and at this time, the matching portion 23 can be arranged on the seat plate 21, or arranged on the back plate 22, or arranged on the side surface of the rotating support shaft 24, so that the connection and matching of the mounting portion 13 and the matching portion 23 can be realized.

[0074] In view of the stability of the support, the matching portion 23 is spaced apart in the left-right direction and has two, and the bearing seat 1 is spaced apart in the front-rear direction and has two mounting groups, each mounting group includes two mounting portions 13 arranged opposite to each other in the left-right direction, so as to be connected with the two matching portions 23.
