[0055] In order to better understand the embodiments of the present application, the carrier provided according to the embodiments of the present application will be described in detail below with reference to the drawings.

[0056] Please refer to Figure 1 、 Figure 3 And Figure 6 , the carrier 100 includes a bearing seat 1 and a seat 2, the bearing seat 1 is formed with a recess area 11 and a bearing area 12; the seat 2 includes a seat plate 21 and a back plate 22 rotationally connected with the seat plate 2, the back plate 22 has a folding state of folding to close to the seat plate 21 and an unfolded state of unfolding to form an angle with the seat plate 21, in the folding state, the back plate 22 is folded to the recess area 11, and the side of the back plate 22 away from the seat plate 21 together with the bearing area 12 forms a combined bearing surface for lying.

[0057] In the unfolded state, the seat plate 21 can be used for children to ride, and the back plate 22 provides support for the upper body of the child, in the folding state, the back plate 22 is attached to the seat plate 21, at this time, the combined bearing surface can be formed with the bearing area 12 to enable the child to lie flat, which can provide both riding function and lying plate function, and the combined form is variable, more flexible, and suitable for different use requirements.

[0058] Further, the seat can be detachably installed in the recess area 11 in a forward attitude and a reverse attitude, in the forward attitude, the seat plate 21 is located on the side away from the bearing area 12 relative to the back plate 22, in the reverse attitude, the seat plate 21 is located on the side toward the bearing area 12 relative to the back plate 22, and in the forward attitude and the reverse attitude, the back plate 22 can be folded.

[0059] In order to facilitate the understanding of the direction, it is defined that the seat plate 21 has opposite first and second ends 21a and 21b, and the back plate 22 is rotationally connected to the first end 21a of the seat plate 21 and can be rotationally adjusted and arranged, wherein, in the forward attitude, the seat plate 21 is located in the recess area 11 and the second end 21b of the seat plate 21 is arranged adjacent to the bearing area 12, in the reverse attitude, the seat plate 21 is located in the recess area 11 and the second end 21b of the seat plate 21 is arranged away from the bearing area 12, and in the forward attitude and / or the reverse attitude, and the back plate 22 is in the folding state, the outer side of the back plate 22 forms a combined bearing surface with the bearing area 12. In this structure, the seat 2 can be installed in the forward attitude or the reverse attitude respectively, so that it has two different directions during use. The seat 2 has two installation states in the forward attitude or the reverse attitude, the combined form is variable, more flexible, and suitable for different use requirements.

[0060] Correspondingly, two children can be seated in the carrier 100, and when the seat 2 and the bearing area 12 are installed in the forward and reverse positions, the two children can be seated in the same direction or opposite directions.

[0061] The bearing seat 1 can be in the form of a support or a bottom plate, and the specific size, material and shape thereof are not limited as long as it can play a supporting function.

[0062] The seat 2 is a structure with a 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's seating.

[0063] The bearing seat 1 can be provided with a groove in a local part, the groove corresponds to form the recessed area 11, and the side of the groove corresponds to form the bearing area 12. Alternatively, the local part of the bearing seat 1 can be irregularly arranged, the local part can be provided with a curved surface, and the curved surface part is concave to form the recessed area 11, and the remaining flat parts correspond to form the bearing area 12. Alternatively, the bearing seat 1 can include two seat plates 21 with different heights, the surface of the seat plate 21 with a higher height forms the bearing area 12, and the stepped space formed between the two seat plates 21 forms the recessed area 11.

[0064] It should be understood that the seat plate 21 and the back plate 22 can be rotatably connected, and in the unfolded state, the seat plate 21 and the back plate 22 should be able to be fixed at a set angle, and 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 at a certain posture, that is, they are attached, so that the back plate 22 will not suddenly open during cooperation with the bearing area 12, thereby ensuring that the child 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 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 it can also be unlocked so that the seat plate 21 and the back plate 22 can rotate relative to each other.

[0065] The present application does not limit the form of the lock structure, and the lock structure only needs to have the functions of unlocking and locking.

[0066] The recessed area 11 and the bearing area 12 are corresponding parts on the bearing seat 1, and the sizes thereof can be the same or different. The size of the recessed area 11 should consider 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.

[0067] Specifically, the shape of the backboard 22 is adapted to at least a part of the recessed area 11 adjacent to the bearing area 12, so that the backboard 22 is connected to the bearing area 12 in the folded state in the forward and / or reverse posture. This arrangement is to avoid the gap between the edge of the seat 2 and the bearing area 12 when the seat 2 is in the folded state, which affects the comfort of the child lying down.

[0068] Since the orientation of the seat 2 is different when the seat 2 is installed in the forward and reverse postures, the side end of the corresponding backboard 22 abutting the bearing area 12 is also different. When the seat 2 is installed in the forward posture, one end of the backboard 22 is connected to the first end 21a of the seat plate 21, and during the conversion from the unfolded state to the folded state, the backboard 22 needs to be flipped towards the direction of the bearing area 12, so that after the conversion to the folded state, the other end of the backboard 22 abuts the bearing area 12. When the seat 2 is installed in the reverse posture, during the conversion from the unfolded state to the folded state, the backboard 22 needs to be flipped away from the direction of the bearing area 12, so that after the conversion to the folded state, the end of the backboard 22 connected to the seat plate 21 abuts the bearing area 12. Therefore, when designing the shape of the backboard 22, the adaptation state of both ends of the backboard 22 to the recessed area 11 needs to be considered.

[0069] In other embodiments, due to the size of the recessed area 11 and the size of the backboard, there is a gap between the backboard and the edge of the bearing area when the backboard is in the folded state in the forward and reverse installation of the seat.

[0070] Based on the above embodiments, in order to ensure the continuity of the combined bearing surface, a detachable connecting plate can be provided, which is installed at the gap. When the seat 2 is in the reverse posture and in the folded state, if a gap is also formed with the bearing area 12, the connecting plate can also be installed at this position, and if there is no gap, the connecting plate can be stored and not used. It should be understood that the connecting plate can also be installed at the exposed position of the recessed area 11 when the seat 2 is in the unfolded state, which can be used as a cover, and users can place some items in the recessed area 11.

[0071] It should be noted that when the backboard 22 is in the folded state and abuts the bearing area 12, it is only necessary to ensure that the combined bearing surface is a continuous abutting plane, and at this time, there can be a fitting gap between the end of the recessed area 11 facing away from the bearing area 12 and the backboard 22, which does not affect the use of the combined bearing surface.

[0072] In some embodiments, the outer side of the backboard 22 is flush with the bearing area 12 in the forward and / or reverse posture and when the backboard 22 is in the folded state. At this time, the combined bearing surface is a plane, i.e., the outer side of the backboard 22 and the bearing area 12 are located on the same horizontal plane. When the backboard 22 is in abutting cooperation with the bearing area 12, the combined bearing surface is a continuous plane.

[0073] In other embodiments, the outer side of the backboard 22 is arranged at an angle with the plane of the bearing area 12 when in the forward and / or reverse posture, and the backboard 22 is in the folded state. That is, the backboard 22 is in an inclined state, and accordingly, the orientation of the backboard 22 when in the folded state is different when in the forward and reverse postures, and thus the inclination angle is also different. For example, when in the forward posture, the outer side of the backboard 22 is inclined upward toward the bearing area 12, which can allow the head of the child to be located in the bearing area 12, and the feet to be on the backboard 22, and thus the feet and lower legs can be lowered along the direction of inclination of the backboard 22. When in the reverse posture, the outer side of the backboard 22 is inclined downward toward the bearing area 12, which can allow the head of the child to be located on the backboard 22, and thus can be slightly raised. It should be understood that the backboard 22 has two sides opposite in the thickness direction, one side always cooperates with the seat plate 21 to provide support for the back of the child drawing, and the other side can be arranged as an inclined surface, thereby achieving the effect of local inclination of the combined bearing surface.

[0074] In other cases, the backboard 22 can also be inclined downward toward the bearing area 12 when the seat 2 is in the folded state in the forward posture, and the present application does not make a limitation in comparison.

[0075] In some embodiments, referring to Figures 1 to 2 , when the seat 2 is in the forward posture and the backboard 22 is in the unfolded state, the second end 21b of the seat plate 21 is spaced apart from the bearing area 12, so as to reserve an accommodation space between the backboard 22 and the bearing area 12. When the child sits on the seat 2 in the forward posture, the feet can be inserted into the accommodation space, so that the accommodation space can serve as a foot space, improving the comfort of the child when riding, and allowing the legs to relax. In other embodiments, the seat plate 21 can also be connected to the bearing area 12 when the seat 2 is in the forward posture, and thus the legs of the child can be placed flat on the bearing area 12 when riding.

[0076] In some embodiments, referring to Figures 4 to 5 , when the seat 2 is in the reverse posture and the backboard 22 is in the unfolded state, the second end 21b of the seat plate 21 is spaced apart from the edge of the recessed area 11, so as to reserve an accommodation space between the backboard 22 and the edge of the recessed area 11. When the child sits on the seat 2 in the reverse posture, the feet can be inserted into the accommodation space, so that the accommodation space can serve as a foot space, improving the comfort of the child when riding, and allowing the legs to relax. In other embodiments, the seat plate 21 can also be connected to the edge of the recessed area 11 when the seat 2 is in the reverse posture, and thus the legs of the child can be directly extended out of the recessed area 11 when riding. If there is space in the part of the bearing seat 1 that is opposite to the bearing area 12, the legs can be placed flat in the space, and if there is no space, the legs can be directly extended out of the vehicle 100.

[0077] In the embodiment, the recessed area 11 forms an accommodation space in the forward and reverse attitudes, so that the child has a space to place his feet when sitting in different directions.

[0078] The utility model does not limit the formation of the accommodation space, which can be the depth of the recessed area 11 itself. By setting the installation position of the seat plate 21 to have a height difference with the bottom of the recessed area 11, the child can place his feet downward in the accommodation space. In other embodiments, a section of the recessed area 11 is concave downward to form a sunken groove, and the accommodation space is arranged corresponding to the sunken groove. At this time, the seat plate 21 can be directly installed at the bottom of the recessed area 11, and the sunken groove is used for placing the child's feet.

[0079] In the embodiment, please refer to Figure 3 The recessed area 11 includes a first groove body 111, a second groove body 112, and a support boss 113 separating the first groove body 111 and the second groove body 112, which are arranged along the front and rear directions. 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 113. The first groove body 111 and the second groove body 112 are respectively used for placing the child's feet in the forward and reverse attitudes, thereby providing a comfortable riding experience for the child.

[0080] The carrier can be used for two children to ride. In some embodiments, the size of the second groove body 112 is larger than that of the first groove body 111. When installed in the forward attitude, the seat plate 2 covers part of the second groove body 112, and the first groove body 111 is exposed outward. At this time, the first groove body 111 forms an avoidance space for the child on the seat 2 to place his feet, and the other child sits on the bearing area 12, both facing forward. When installed in the reverse attitude, the seat plate covers the first groove body 111. At this time, the other child sits on the bearing area 12, and the two children ride towards each other. By setting the second groove body 112 to be larger, the second groove body 112 can be used for two children to place their feet at the same time.

[0081] It should be understood that the bottom wall of the first groove body 111 and / or the second groove body 112 can be throughly arranged, so that the child's feet can be suspended when riding.

[0082] The utility model discloses not limit seat 2 to realize the fixed mode of positive attitude and reverse attitude, specifically, the bearing seat 1 is provided with the installation portion 13, and the connecting place of seat board 21 and backboard 22 is provided with the cooperation portion 23, and the cooperation portion 23 is detachably connected with the installation portion 13. For example, the installation portion 13 can be set in the middle position of recessed area 11, and the cooperation portion 23 is correspondingly set on seat board 21, and the shape and structure of cooperation portion 23 and installation portion 13 are set to allow cooperation portion 23 to be connected and cooperated with installation portion 13 in positive or reverse, so when the positive attitude and reverse attitude of seat 2 are converted, seat 2 only needs to be lifted, so that installation portion 13 and cooperation portion 23 are separated, and then the direction of seat 2 is changed artificially.

[0083] Furthermore, please refer to Figure 4 The bearing seat 1 also has support structure 14, and the support structure 14 is used to support seat board 21 in the folded state; in the folded state, the support structure 14 supports one end of seat board 21 away from backboard 22; the support structure 14 includes a protrusion arranged on the inner wall of the recessed area 11; the support structure 14 is provided with two, and the two support structures 14 are arranged along the front and rear directions to support seat board 21 in the positive attitude installation and the reverse attitude installation respectively. Thus, seat 2 has good load-bearing effect.

[0084] In other embodiments, please refer to Figure 6 The seat 2 also includes a rotating support shaft 24, and the first end 21a of the seat board 21 and the backboard 22 can be rotatably connected with the rotating support shaft 24; the rotating support shaft 24 is provided with the cooperation portion 23. Because the interval between the rotating support shaft 24 and the edge of the recessed area 11 changes when the direction of seat 2 is changed, the size of the recessed area 11 domain needs to be reasonably set, so that the interval between the installation portion 13 and the two ends of the recessed area 11 in the front and rear directions can meet the size that can accommodate seat board 21 and backboard 22.

[0085] When the seat 2 is provided with the lock structure, the rotating support shaft 24 can be part of the lock structure, and cooperate with seat board 21 and backboard 22.

[0086] It should be understood that the installation 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 cooperation portion 23 is arranged at the side end of seat 2, and the installation portion 13 is arranged at the side wall of the recessed area 11.
