[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] It should be noted that if a directional indication is involved in the embodiment of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0051] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0052] In common riding vehicles, such as strollers, treadmills, and tractors, the orientation of the seats is generally fixed when the seats are set. The direction of the seats can be adjusted in some strollers, usually by providing a rotating device under the seats so that the seats can be rotated a certain angle in the original installation position, thereby achieving seat rotation. At the same time, the seats generally only have two functions: folding and storing for sitting and unfolding for sitting, that is, the application function in the vehicle is single.

[0053] Some child seats can realize the functions of sitting and lying at the same time. This structure is achieved by rotating the seat and the back panel of the seat to be in the same plane, so that the seat panel and the back panel are spliced ​​together to form a bed board for the child to lie on. That is, the sitting function and the lying function are achieved by adjusting the angle between the seat panel and the back panel.

[0054] Based on this, in order to increase the diversity of uses of riding vehicles, the present invention proposes a carrier suitable for riding vehicles with load-bearing functions, for example, it can be a fixed child seat, a dining chair, etc., or it can be a movable stroller, a treadmill, a trailer, a tractor, etc.

[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 accompanying drawings.

[0056] Please refer to Figure 1 , Figure 3 and Figure 6 The carrier 100 includes a load-bearing seat 1 and a seat 2, the load-bearing seat 1 is formed with a recessed area 11 and a load-bearing area 12; the seat 2 includes a seat plate 21 and a back plate 22 rotatably connected to the seat plate 2, the back plate 22 has a folded state folded to be close to the seat plate 21, and an unfolded state at an angle to the seat plate 2121. In the folded state, the back plate 22 is folded into the recessed area 11, and the side of the back plate 22 away from the seat plate 21 together with the load-bearing area 12 forms a combined load-bearing surface for lying down.

[0057] When in the unfolded state, the seat plate 21 can be used for children to sit on, and the back plate 22 provides support for the upper body of the child. When in the folded state, the back plate 22 fits against the seat plate 21, and at this time, can form a combined bearing surface with the bearing area 12 for the child to lie flat. It can provide both a sitting function and a lying function. The combination form is changeable and more flexible to meet different usage needs.

[0058] Furthermore, the seat can be detachably installed in the recessed area 111 in a forward posture and a reverse posture. In the forward posture, the seat panel 21 is located on the side away from the load-bearing area 12 relative to the back panel 22. In the reverse posture, the seat panel 21 is located on the side facing the load-bearing area 12 relative to the back panel 22. In both the forward posture and the reverse posture, the back panel 22 can be folded.

[0059] In order to facilitate the understanding of the orientation, the seat plate 21 is defined as having a first end 21a and a second end 21b opposite to each other, and the back plate 22 is rotatably connected to the first end 21a of the seat plate 21 and can be rotatably adjusted, wherein, in the forward posture, the seat plate 21 is located in the recessed area 11 and the second end 21b of the seat plate 21 is disposed adjacent to the bearing area 12, and in the reverse posture, the seat plate 21 is located in the recessed area 11 and the second end 21b of the seat plate 21 is disposed away from the bearing area 12, and in the forward posture and / or reverse posture, and when the back plate 22 is in a folded state, the outer side surface of the back plate 22 forms a combined bearing surface with the bearing area 12. In this structural form, the seat 2 can be installed in a forward posture or a reverse posture, respectively, so as to have two different orientations during use. The seat 2 has two installation states when installed in the forward posture or the reverse posture, and the combination form is changeable, more flexible, and adaptable to different usage requirements.

[0060] Accordingly, two children can ride in the vehicle 100 , respectively on the seat 2 and the carrying area 12 . When the vehicle 100 is installed in the forward and reverse postures, the two children can ride in the same direction or facing each other.

[0061] The support seat 1 can be provided in the form of a bracket or a base plate. The specific size, material and shape 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 seat plate 21 and the back plate 22 can be combined to form a seat pocket structure, that is, the seat plate 21 has a certain curvature and can fit the child's buttocks, thereby providing a comfortable riding experience for the child.

[0063] The bearing seat 1 may be partially provided with grooves, the grooves correspondingly form the recessed area 11, and the side of the grooves correspondingly form the bearing area 12. The bearing seat 1 may also be partially provided with irregular settings, partially provided with curved surfaces, and the curved surface portion is concave to form the recessed area 11, and the remaining flat portions correspondingly form the bearing area 12. The bearing seat 1 may also be provided with two seat plates 21 of different heights, the surface of the seat plate 21 with the 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 rotated and matched. In the unfolded state, the seat plate 21 and the back plate 22 should be fixed at a set angle, and the 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 fixed in a certain posture, that is, the two fit together, so that the back plate 22 will not suddenly flip open during the cooperation process with the load-bearing area 12, thereby ensuring that children can lie safely on the combined load-bearing surface without worrying about the back plate 22 suddenly changing its state due to external forces. Based on this requirement, a locking structure should be set on the seat 2, and the locking structure needs to be able to lock the seat plate 21 and the back plate 22 in a folded state or an unfolded state, so that the angle of the seat plate 21 and the back plate 22 is fixed, and can be unlocked so that the seat plate 21 and the back plate 22 can rotate relative to each other.

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

[0066] The recessed area 11 and the bearing area 12 are both corresponding parts on the bearing seat 1. The sizes of the two can be the same or different. The size of the recessed area 11 should take into account the design size of the back panel 22 when designing. The depth of the recessed area 11 also needs to adapt to the thickness of the seat 2 when it is in a folded state, so as to avoid a height difference between the outer side of the back panel 22 and the bearing area 12 when the seat 2 is in a folded state.

[0067] Specifically, the shape of the back plate 22 is adapted to at least a portion of the recessed area 11 adjacent to the carrying area 12, so that in the forward posture and / or the reverse posture, and when the back plate 22 is in the folded state, the back plate 22 is connected to the carrying area 12. This arrangement is to avoid the formation of a gap between the edge of the seat 2 and the carrying 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 posture and the reverse posture, the side ends of the corresponding back panel 22 adjacent to the load-bearing area 12 are also different. When the seat 2 is installed in the forward posture, one end of the back panel 22 is connected to the first end 21a of the seat panel 21. In the process of converting from the unfolded state to the folded state, the back panel 22 needs to be flipped in the direction where the load-bearing area 12 is located. Therefore, after converting to the folded state, the other end of the back panel 22 is adjacent to the load-bearing area 12; when the seat 2 is installed in the reverse posture, in the process of converting from the unfolded state to the folded state, the back panel 22 needs to be flipped away from the direction where the load-bearing area 12 is located. Therefore, after converting to the folded state, the end of the back panel 22 connected to the seat panel 21 is adjacent to the load-bearing area 12. Therefore, when designing the shape of the back panel 22, it is necessary to simultaneously consider the adaptation state of its two ends with the recessed area 11.

[0069] In other embodiments, due to the size setting of the recessed area 11 and the size matching of the back panel, when the seat is installed in the forward and reverse directions, there is a situation where the back panel is in a folded state and the edge of the load-bearing area is spaced apart.

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

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

[0072] In some embodiments, in the forward posture and / or the reverse posture, and when the back panel 22 is in the folded state, the outer side surface of the back panel 22 is flush with the carrying area 12. At this time, the combined carrying surface is a plane, that is, the outer side surface of the back panel 22 and the carrying area 12 are located in the same horizontal plane. When the back panel 22 and the carrying area 12 are in engagement, the combined carrying surface is a continuous plane.

[0073] In other embodiments, in the forward posture and / or reverse posture, and when the backboard 22 is in the folded state, the outer side surface of the backboard 22 is set at an angle with the plane where the load-bearing area 12 is located. That is, the backboard 22 is in an inclined state. Accordingly, in the forward posture and the reverse posture, the orientation of the backboard 22 when folded is different, so the inclination angle is also different. For example, in the forward posture, the outer side surface of the backboard 22 is tilted upward toward the load-bearing area 12, so that the child's head can be located in the load-bearing area 12, and the feet are on the backboard 22. At this time, the feet and calves can droop along the inclination direction of the backboard 22; in the reverse posture, the outer side surface of the backboard 22 is tilted downward toward the load-bearing area 12, so that the child's head can be located on the backboard 22, so that it can be slightly raised. It should be understood that the backboard 22 has two side surfaces opposite to each other in the thickness direction, one side surface is always in cooperation with the seat plate 21 to provide support for the back of the child, and the other side surface can be set as an inclined surface, so as to achieve the above-mentioned partial inclination effect of the combined load-bearing surface.

[0074] In other cases, it may also be in the forward posture, when the seat 2 is in the folded state, the back panel 22 is tilted downward toward the carrying area 12, and the present invention does not limit this.

[0075] In some embodiments, please refer to Figure 1 to Figure 2 , when the seat 2 is in the forward posture and the back plate 22 is in the unfolded state, the second end 21b of the seat plate 21 is spaced from the load-bearing area 12, so that a storage space is reserved between the back plate 22 and the load-bearing area 12. When a child sits on the seat 2 in the forward posture, his feet can be extended into the storage space, so that the storage space can be used as a footrest, improving the comfort of the child and allowing the legs to relax. In other embodiments, when the seat 2 is in the forward posture, the seat plate 21 can also be connected to the load-bearing area 12, and the child's legs can be placed flat on the load-bearing area 12 when sitting.

[0076] In some embodiments, please refer to Figures 4 to 5 , when the seat 2 is in the reverse posture and the back plate 22 is in the unfolded state, the second end 21b of the seat plate 21 is spaced from the edge of the recessed area 11, so that an accommodation space is reserved between the back plate 22 and the edge of the recessed area 11. When a child sits on the seat 2 in the reverse posture, his feet can be extended into the accommodation space, so that the accommodation space can be used as a footrest space, thereby improving the riding comfort of the child and allowing the legs to relax. In other embodiments, when the seat 2 is in the reverse posture, the seat plate 21 can also be connected to the edge of the recessed area 11. At this time, when the child is sitting, the legs can be directly extended out of the recessed area 11. If there is still space in the part of the support seat 1 where the recessed area 11 is facing away from the support area 12, the legs can be placed flat in the space. If there is no space, the legs can be directly extended out of the carrier 100.

[0077] In this embodiment, when the seat 2 is in the forward posture and the reverse posture, the recessed area 11 forms an accommodation space, so that when a child sits on the seat 2 in different orientations, there is space for the feet.

[0078] The present invention does not limit the formation method 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 to form a sinking groove, and the accommodation space is set corresponding to the sinking groove. In this case, the seat plate 21 can be directly installed at the bottom of the recessed area 11, and the sinking groove is corresponding to the placement of the child's feet.

[0079] In this embodiment, please refer to Figure 3 The recessed area 11 includes a first groove body 111, a second groove body 112 and a supporting boss 113 separating the first groove body 111 and the second groove body 112, which are arranged at intervals along the front-to-back direction, wherein the second groove body 112 is located beside the load-bearing area 12. When in the unfolded state, the seat plate 2 is supported on the supporting boss 113, and the first groove body 111 and the second groove body 112 are respectively used for children to place their feet in the forward posture and the reverse posture, thereby providing a comfortable riding experience for the children.

[0080] The carrier can accommodate two children. In some embodiments, the size of the second slot 112 is larger than that of the first slot 111. When installed in the forward posture, the seat plate 2 covers part of the second slot 112, and the first slot 111 is exposed outward. At this time, the first slot 111 forms an escape space for the child on the seat 2 to place his feet, and another child sits in the carrying area 12, and both children face forward. When installed in the reverse posture, the seat plate covers the first slot 111, and at this time, another child sits in the carrying area 12, and the two children sit facing each other. By setting the second slot 112 larger, the second slot 112 can accommodate two children to place their feet at the same time.

[0081] It should be understood that the bottom wall of the first trough body 111 and / or the second trough body 112 may be arranged to be through-connected, and in this case, the feet of the child may be suspended in the air when riding.

[0082] The present invention does not limit the fixing method of the seat 2 to achieve the forward posture and the reverse posture. Specifically, the support seat 1 is provided with a mounting portion 13, and a matching portion 23 is provided at the connection between the seat plate 21 and the back plate 22, and the matching portion 23 is detachably connected to the mounting portion 13. For example, the mounting portion 13 may be provided in the middle of the recessed area 11, and the matching portion 23 may be provided on the seat plate 21 accordingly. The shape and structure of the matching portion 23 and the mounting portion 13 are such that the matching portion 23 can be connected and matched with the mounting portion 13 in the forward direction or the reverse direction. In this way, when the forward posture and the reverse posture of the seat 2 are switched, it is only necessary to lift the seat 2 to separate the mounting portion 13 and the matching portion 23, and then manually change the direction of the seat 2.

[0083] In addition, please refer to Figure 4 The bearing seat 1 also has a support structure 14, which is used to support the seat plate 21 in the folded state; in the folded state, the support structure 14 supports the end of the seat plate 21 away from the back plate 22; the support structure 14 includes a protrusion arranged on the inner wall of the recessed area 11; there are two support structures 14, which are arranged in the front-to-back direction to support the seat plate 21 respectively when installed in the forward posture and when installed in the reverse posture. Thus, the seat 2 has a good load-bearing effect.

[0084] In other embodiments, please refer to Figure 6 The seat 2 further includes a rotation support shaft 24, and the first end 21a of the seat plate 21 and the back plate 22 can be rotatably connected to the rotation support shaft 24; a matching portion 23 is provided on the rotation support shaft 24. Since the interval between the rotation support shaft 24 and the edge of the recessed area 11 will change when the seat 2 changes direction, it is necessary to reasonably set the size of the recessed area 11 so that the interval between the mounting portion 13 and the two ends of the recessed area 11 in the front-back direction can meet the size of the seat plate 21 and the back plate 22.

[0085] When a locking structure is provided on the seat 2 , the rotation support shaft 24 can serve as a part of the locking structure and cooperate with the seat plate 21 and the back plate 22 .

[0086] It should be understood that the mounting portion 13 can be disposed at the bottom of the recessed area 11 or at the side of the recessed area 11 . In one embodiment, the matching portion 23 is disposed at the side end of the seat 2 , and the mounting portion 13 is disposed on the side wall of the recessed area 11 .

[0087] Specifically, the present invention does not limit the structural form of the matching portion 23 and the mounting portion 13. In some implementations, one of the matching portion 23 and the mounting portion 13 is set as a limiting groove, and the other is set as a limiting protrusion. Considering the functions of the limiting groove and the limiting protrusion, the limiting groove can be set as a T-shaped groove, a dovetail groove, or other structural forms that can simultaneously play the role of plugging and anti-slipping, and the limiting protrusion is adapted to the shape of the limiting groove. In this embodiment, since the mounting portion 13 is set on the side of the recessed area 11, the matching direction of the limiting groove and the limiting protrusion is up and down, that is, the limiting groove is at least a structure with an open upper end, so that the limiting protrusion can be plugged in and out in the up and down directions. In this embodiment, the upper end and the side end of the limiting groove are both open.

[0088] In other implementations, one of the matching portion 23 and the mounting portion 13 is configured as a buckle, and the other is configured as a slot, and the mounting and limiting are achieved by elastic snap-fitting.

[0089] When the mounting portion 13 and the matching portion 23 are matched laterally, considering the stability of the seat 2 after installation, a supporting matching structure can be provided on the side opposite to the mounting portion 13, so as to achieve a balancing force effect when the mounting portion 13 and the matching portion 23 are connected. Alternatively, two mounting portions 13 and two matching portions 23 can be provided correspondingly, so as to achieve a balancing effect.

[0090] In some implementations, at least two mounting portions 13 are arranged at intervals along the front-back direction; in the forward posture, the matching portion 23 is connected to a mounting portion 13 close to the load-bearing area 12; in the reverse posture, the matching portion 23 is connected to a mounting portion 13 far from the load-bearing area 12. At this time, the matching portion 23 can be matched with any mounting portion 13. When the forward posture and reverse posture of the seat 2 are switched, the seat 2 needs to be lifted to separate the current mounting portion 13 and the matching portion 23, and then the direction of the seat 2 is manually changed, and the matching portion 23 is connected to another mounting portion 13, so as to achieve the direction switch.

[0091] In this embodiment, the two mounting parts 13 are both arranged on the side wall of the recessed area 11 and are spaced in the front-back direction. In one way, the two mounting parts 13 are arranged on the same side wall of the recessed area 11, and the matching part 23 is arranged on the side of the seat 2. The forward posture and the reverse posture can be adjusted by replacing the connected mounting parts 13 and the mounting direction. At this time, the support of the seat 2 needs to be considered; in another way, the two mounting parts 13 are arranged on the two opposite side walls of the recessed area 11. In this case, the matching part 23 can be arranged on the first end 21a of the seat plate 21, or on the back plate 22, or on the side surface of the rotating support shaft 24, so that the connection and matching of the mounting parts 13 and the matching part 23 can be achieved.

[0092] Considering the stability of the support, two matching parts 23 are arranged at intervals along the left-right direction, and two installation groups are arranged at intervals along the front-back direction on the bearing seat 1, and each installation group includes two installation parts 13 arranged oppositely along the left-right direction to connect with the two matching parts 23. That is, the recessed area 11 has two opposite first side walls, and each first side wall is provided with two installation parts 13 arranged at intervals in the front-back direction, so that when the seat 2 is installed in different installation directions, it can be connected with the two matching parts 23 accordingly. In one case, the two first side walls are arranged oppositely in the left-right direction, and the two matching parts 23 are arranged on the opposite sides of the seat 2. At this time, the seat 2 is provided with opposite connection and support force in the left-right direction by relying on the cooperation between the two sides of the seat 2 and the two first side walls of the recessed area 11. When the first groove body 11 and the second groove body 112 are formed on the recessed area 11, the two installation parts 13 can be respectively located above the first groove body 11 and the second groove body 112. In another case, the two first side walls are arranged opposite to each other in the front-rear direction, and the two matching portions 23 are arranged on the same side of the seat plate 21 , or on the back plate 22 , or on the side surface of the rotation support shaft 24 .

[0093] In the first embodiment, please refer to Figures 1 to 3 The bearing seat 1 has a bottom plate, and a groove is partially arranged on the upper end surface of the bottom plate to form a recessed area 11. The end surface of the bottom plate adjacent to the recessed area 11 forms a bearing area 12. A first groove body 11 and a second groove body 112 are formed on the recessed area 11. Two limiting grooves are respectively arranged on the two side walls opposite to each other in the left and right directions of the recessed area 11. The two limiting grooves on each side wall correspond to the first groove body 11 and the second groove body 112 respectively. The seat 2 consists of a seat plate 21, a back plate 22 and a rotating support shaft 24. Both side ends of the rotating support shaft 24 in the left and right directions are exposed to the seat plate 21 and the back plate 22, and limiting protrusions are respectively arranged on the two side ends.

[0094] When installed in the forward posture, the limiting protrusion is plugged into and matched with the two limiting grooves away from the load-bearing area 12. At this time, the seat plate 21 can overlap the support boss 113 between the first groove body 11 and the second groove body 112. When the seat 2 is in the unfolded state, the back plate 22 is tilted, the second groove body 112 is exposed, and the first groove body 111 is blocked by the seat 2. The child sits facing the load-bearing area 12 and the feet can be placed in the exposed groove body. When the seat 2 is in the folded state, the seat plate 21 and the rotating support shaft 24 remain stationary, and the matching state of the limiting groove and the limiting protrusion remains unchanged, driving the back plate 22 to rotate relative to each other, thereby converting to the folded state. At this time, the first groove body 11 and the second groove body 112 are both blocked by the seat 2, and the edge of the back plate 22 is connected to the load-bearing area 12 and is set flush. At this time, a complete flat plate is formed, and the child can lie down.

[0095] When the reverse posture is converted, the seat 2 is lifted upward as a whole. At this time, the seat 2 can be kept in the folded state or converted to the unfolded state. The user can choose a form that is easy to hold. In the process of lifting the seat 2 as a whole, the limiting protrusion is separated from the current limiting groove, and the direction of the seat 2 is changed so that the limiting protrusion is plugged and matched with the two limiting grooves near the load-bearing area 12. At this time, the seat plate 21 can overlap the support boss 113 between the first groove body 11 and the second groove body 112. When the seat 2 is in the unfolded state, the back plate 22 is inclined, the second groove body 112 is blocked, and the first groove body 111 is exposed. The child sits with his back to the load-bearing area 12, and his feet can be placed in the exposed groove body. When the seat 2 is in the folded state, the seat plate 21 and the rotating support shaft 24 remain stationary, and the matching state of the limiting groove and the limiting protrusion remains unchanged, driving the back plate 22 to rotate relatively, thereby converting to the folded state. At this time, the first groove body 11 and the second groove body 112 are both blocked by the seat 2, and the end of the back plate 22 connected to the seat plate 21 is connected to the bearing area 12 and arranged flush, so as to form a complete flat plate on which the child can lie.

[0096] In the second embodiment, compared with the first embodiment, two limiting grooves are respectively provided on the two side walls opposite to each other in the front and rear directions of the recessed area 11, and the two limiting grooves on each side wall correspond to the first groove body 111 or the second groove body 112 respectively, and two spaced limiting protrusions are provided on the side faces in the front and rear directions of the first end 21a of the seat 2.

[0097] When installed in the forward posture, the limiting protrusion is plugged into and matched with the two limiting grooves away from the load-bearing area 12. At this time, the seat plate 21 can overlap the support boss 113 between the first groove body 11 and the second groove body 112. When the seat 2 is in the unfolded state, the back plate 22 is tilted, the second groove body 112 is exposed, and the first groove body 111 is blocked by the seat 2. The child sits facing the load-bearing area 12 and the feet can be placed in the exposed groove body. When the seat 2 is in the folded state, the seat plate 21 and the rotating support shaft 24 remain stationary, and the matching state of the limiting groove and the limiting protrusion remains unchanged, driving the back plate 22 to rotate relative to each other, thereby converting to the folded state. At this time, the first groove body 11 and the second groove body 112 are both blocked by the seat 2, and the edge of the back plate 22 is connected to the load-bearing area 12 and is set flush. At this time, a complete flat plate is formed, and the child can lie down.

[0098] When the reverse posture is converted, the seat 2 is lifted upward as a whole, and the seat 2 is converted to the unfolded state, so that the user can intuitively observe the position of the limiting protrusion. In the process of lifting the seat 2 as a whole, the limiting protrusion is separated from the current limiting groove, and the direction of the seat 2 is changed so that the limiting protrusion is plugged and matched with the two limiting grooves near the load-bearing area 12. At this time, the seat plate 21 can overlap the support boss 113 between the first groove body 11 and the second groove body 112. When the seat 2 is in the unfolded state, the back plate 22 is tilted, the second groove body 112 is blocked, and the first groove body 111 is exposed. The child sits with his back to the load-bearing area 12, and his feet can be placed in the exposed groove body. When the seat 2 is in the folded state, the seat plate 21 and the rotating support shaft 24 remain stationary, and the matching state of the limiting groove and the limiting protrusion remains unchanged, driving the back plate 22 to rotate relatively, thereby converting to the folded state. At this time, the first groove body 11 and the second groove body 112 are both blocked by the seat 2, and the end of the back plate 22 connected to the seat plate 21 is connected to the bearing area 12 and arranged flush, so as to form a complete flat plate on which the child can lie.

In the forward posture, when the seat 2 is in the unfolded state, the back plate 22 is tilted, the second groove body 112 is exposed, and at least part of the first groove body 111 is blocked by the seat 2. The child sits facing the load-bearing area 12, and the feet can be placed in the exposed groove body. When the seat 2 is in the folded state, the seat plate 21 remains stationary, and the matching state of the limiting groove and the limiting protrusion remains unchanged, driving the back plate 22 to rotate relative to each other, thereby converting to the folded state. At least the second groove body 112 is blocked by the seat 2, and the edge of the back plate 22 is connected to the load-bearing area 12 and is set flush. At this time, a complete flat plate is formed, and the child can lie down.

[0101] When the reverse posture is converted, the seat 2 is lifted upward as a whole, the seat 2 is rotated, and then the limiting protrusion is inserted into the limiting groove. When the seat 2 is in the unfolded state, the back plate 22 is tilted, the second groove body 112 is blocked, and the first groove body 111 is exposed. The child sits with his back to the load-bearing area 12, and his feet can be placed in the exposed groove body. When the seat 2 is in the folded state, the seat plate 21 remains stationary, and the matching state of the limiting groove and the limiting protrusion remains unchanged, driving the back plate 22 to rotate relatively, thereby converting to the folded state. At this time, at least the second groove body 112 is blocked by the seat 2, and the edge of the back plate 22 is connected with the load-bearing area 12 and is set flush. At this time, a complete flat plate is formed, and the child can lie down.

That is, the carrier 100 includes a plurality of side enclosures 6 and a top cover 7 that are spliced ​​and arranged, so that the bearing area 12 and the recessed area 11 can be in a closed space, so that the child is better protected.

[0107] It should be understood that the size of the top cover 7 may be consistent with the size of the bearing seat 1, or may be different. Figure 1 In the embodiment, the size of the top cover 7 is smaller than the size of the supporting base 1.

[0108] It should be understood that the carrier 100 may be composed of a bearing seat 1 and a side enclosure 6 , or may be composed of a bearing seat 1 and a top cover 7 , or may be composed of a bearing seat 1 , a side enclosure 6 and a top cover 7 .

[0109] In some embodiments, the enclosures facing upward and near the recessed area 11 are movably arranged to form an entrance and exit. At least one enclosure is movably arranged so that the side corresponding to the enclosure movably arranged in the load-bearing area 12 forms an entrance and exit a. Specifically, the enclosures facing upward and near the recessed area 11 are movably arranged to form an entrance and exit a. The present invention does not limit the movable form of the enclosure, which can be rotatably connected at the top or bottom so as to be flipped in the up and down direction, or can be rotatably connected at the opposite sides so as to open the entrance and exit a.

[0110] When the vehicle 100 includes a plurality of spliced ​​side enclosures 6 and a top cover 7, the movable enclosure can be rotatably connected to the top cover 7, thereby realizing the opening and closing of the entrance a.

[0111] In one embodiment, please refer to Figure 1 and Figure 3 , the various parts are described with reference to the front-to-rear direction and the up-down direction. The carrier 100 is composed of an upper bracket assembly, a front canopy 5, a front bracket assembly, a bottom bracket assembly, and a rear bracket assembly.

The end of the front canopy 5 is rotatably connected to the upper bracket assembly so that it can be set at an angle to the front bracket assembly, or embedded in the front bracket assembly. The part of the front bracket assembly corresponding to the front canopy 5 is open to form an entrance and exit a.

[0112] It should be understood that, considering that the front canopy 5 is a movable component, it has a propped-up state in which it rotates to open the entrance a, and a closed state in which it rotates to close the entrance a. Therefore, the compatibility of the corresponding fabric should be considered, that is, its size should be able to adapt to the propping up and closing of the front canopy 5, and it should be well connected and matched in the closed state and the propped-up state, so as to play a shielding function.

[0113] The carrier 100 can be a fixed carrier 100 or a movable carrier 100. In some embodiments, a rolling structure 3 is provided at the bottom of the carrier 1. The rolling structure 3 is a wheel assembly, which enables the carrier 100 to move. In the embodiment of the present invention, four wheels are provided at the bottom of the carrier 1. The two wheels at the front side are universal wheels that can change the direction of travel at will, and the two wheels at the rear side are directional wheels that cooperate with the front wheels for movement.

[0114] It should be understood that for different application scenarios of the vehicle 100, the multiple wheels may be configured differently. For example, when the vehicle 100 is used as a treadmill, the diameters of the two rear wheels are larger than the diameters of the two front wheels to accommodate movement. When the vehicle 100 is used as a cart, the diameters of the four wheels are the same.

[0115] Based on the above embodiments, in one embodiment, the carrier 100 includes a handle assembly 4 disposed on the support seat 1.

[0117] In the embodiment of the present invention, the carrier 100 includes a rolling structure 3, a push handle assembly 4 and a tow bar assembly, that is, the carrier 100 is used as a tow vehicle, so as to adapt to different usage scenarios. It should be understood that, considering the conversion of different scenarios, the push handle assembly 4 can be set to be rotatably connected so that it can be folded and stored, and the tow bar assembly can be set to be detachably connected so that it can be disassembled when the carrier 100 is used only as a cart.

[0118] It should be noted that the above-mentioned carrier 100 structure can also be set as a foldable structure, that is, the support seat 1 is rotatably connected to a part of the enclosure, and the top cover 7 is rotatably connected to a part of the enclosure.

[0119] In one embodiment, the carrier 100 is composed of a bottom bracket assembly, a front bracket assembly, and a rear bracket assembly. The rear bracket assembly is composed of an upper support rod and a lower support rod that are rotatably connected. The bottom bracket assembly extends in the front-to-back direction, and the front bracket assembly and the rear bracket assembly each extend in the up-down direction. The lower portion of the lower support rod is rotatably connected to the rear portion of the bottom bracket assembly, the upper portion of the lower support rod is rotatably connected to the lower portion of the upper support rod, the lower portion of the front bracket assembly is rotatably connected to the front of the bottom bracket assembly, and the upper portion of the front bracket assembly is rotatably connected to the upper support rod. The carrier 100 has a larger riding space in the unfolded state, and the load-bearing area 12 is located in the riding space, which can improve the comfort of children riding. When the carrier 100 is folded, the front bracket assembly is flipped backwards and folded above the bottom bracket assembly, and the upper support rod and the lower support rod are relatively folded and stacked between the front bracket assembly and the bottom bracket assembly, which significantly reduces the size and provides convenience for users' daily storage and carrying.

[0120] Specifically, the bottom bracket assembly includes two groups of bottom support rods which are arranged on the left and right sides and extend in the front-back direction. The front part of each group of bottom support rods is provided with a front wheel assembly, and the rear part is provided with a rear wheel assembly. The front wheel assembly and the rear wheel assembly together constitute a rolling structure 3. The front bracket assembly includes two front support rods which are arranged on the left and right sides and extend in the up-down direction. The front support rod has a certain curvature. Two lower support rods are provided, which are arranged on the left and right sides and extend in the up-down direction. Two upper support rods are provided, which are arranged on the left and right sides and extend in the up-down direction. The push handle assembly 4 includes two push handle rods which are arranged on the left and right sides. On the left and right sides of the vehicle 100, the lower part of the lower support rod is connected to the rear part of the bottom support rod, the lower part of the front support rod is rotatably connected to the front part of the bottom support rod, the upper part of the upper support rod is rotatably connected to the upper part of the front support rod, the lower part of the upper support rod is rotatably connected to the upper part of the lower support rod, and the lower part of the push handle rod is rotatably connected to the upper part of the upper support rod.

[0121] Among them, the lower support rod, the upper support rod, and the front support rod are combined to form an enclosure. Based on the symmetrical structure, there are two enclosures of this structural form. Two upper support rods and two lower support rods form an enclosure, and two front support rods are combined to form an enclosure. The top cover 7 is installed on the part of the front support rod and the ends of the two upper support rods. The front canopy 5 is rotatably installed on the two front support rods and is located in the space defined by the two front support rods. The front canopy 5 is composed of a U-shaped frame and is arranged in an arc shape, and its curvature is adapted to the curvature of the front support rod.

[0122] In addition, considering the convenience of holding the seat 2, a card slot can be set on the outer side of the back plate 22, which can be convenient for the user to hold with his hand. The card slot is set at a position close to one end of the back plate 22, which can not only confirm whether the seat 2 is currently in a forward posture or a reverse posture through the orientation of the card slot, so that the user can judge the next action when different usage requirements are met. The card slot can also be used as a holding part for the operator. For example, when switching between the forward posture and the reverse posture, the seat 2 is pulled up through the card slot, so that the seat 2 and the bearing seat 1 are separated, and it can also be convenient for the operator to hold when the seat is switched from the folded state to the unfolded state.

[0123] Based on the structural form of setting the side enclosure on the periphery of the bearing seat, in another embodiment, please refer to Figures 7 and 8The movable enclosure arranged in the front and rear upward direction and close to the recessed area 11 is set as a front canopy 5. The front canopy 5 is opened to form an entrance and exit a. The front canopy 5 includes a first extension section 51 and a second extension section 52 arranged at an angle. The front canopy 5 includes a first extension section 51 and a second extension section 52 arranged at an angle. Under this structural form, the matching frame corresponding to the front canopy 5 is also arranged at an angle, so that a larger space is formed between the front canopy 5 and the supporting seat 1 when the front canopy 5 is opened or closed. When the seat 2 is unfolded, a larger riding space can be provided for the child, so that the backboard 22 and the second extension section 52 have sufficient space in the upper and lower directions to prevent the child's head from being against the front canopy 5, and at the same time, sufficient space is provided for the child's legs and hands.

[0124] It should be noted that the opening angle of the entrance a can be adjusted, that is, the unfolding angle of the front canopy 5 can be adjusted, so that the front canopy 5 can be fixed at a desired position as required. It should be understood that a corresponding limit stop structure needs to be provided to achieve the fixation of the front canopy 5 at a certain angle, and the specific structural form is not limited in the present invention.

[0125] In the structural setting of the front canopy 5, the front canopy 5 can be L-shaped, and the first extension section 51 and the second extension section 52 have an arc transition. In other embodiments, the second extension section 52 can also be set to be an arc shape, so that a part of the second extension section 52 protrudes away from the back panel 22, thereby making the riding space larger.

[0126] When the carrier 100 is pushed or mounted on a bicycle and driven to move, the carrier 100 further includes a laser warning device 8 for safety considerations. The laser warning device 8 is disposed on the support base 1 and is used to project a light beam toward the peripheral side of the support base 1. The laser warning device 8 can project light bars on the bottom surface of the peripheral side of the support base 1, and these light bars can form a light display frame around the support base 1, thereby alerting passing vehicles.

[0127] Thereby, a warning is given to the passing pedestrians or vehicles, and the safety performance is improved. Specifically, the laser warning device 8 can be located on the side of the enclosure in the left and right directions of the bearing seat 1, with the laser head projecting downward.

[0128] Specifically, a control warning light may be provided on the carrier 100 , and the warning light may be provided on the enclosure at the rear side of the support seat 1 , or on the enclosure at the top.

[0129] In this embodiment, a control box b is set on the supporting seat 1, and related structures are connected through lines, so that the user can control the switch of the laser warning device 8 and the warning light, or control the opening angle of the front canopy 5 by operating the buttons or touching the keys on the control box b.

[0130] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
