The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0061] In one aspect, the present invention provides a baby carrier. Figures 1 to 3 As shown, the infant carrier includes a waist belt 1, a shoulder belt 2, and a child support member 3 connected to the waist belt 1 and the shoulder belt 2, respectively. The shoulder belt 2 is arranged roughly along the depth direction of the child support member 3. One side of the child support member 3 is connected to the waist belt 1, and the side of the child support member 3 away from the waist belt 1 is detachably or non-detachably connected to the shoulder belt 2. That is, the upper side of the child support member 3 is connected to the shoulder belt 2, and the lower side of the child support member 3 is connected to the waist belt 1. In this embodiment, the upper side of the child support member 3 is detachably connected to the shoulder belt 2 via a connecting component (such as a buckle). In other embodiments, the child support member 3 may also be fixedly connected to the shoulder belt 2. This application does not limit the specific connection method between the child support member 3 and the shoulder belt 2. Refer to Figures 1 to 3 The child support 3 includes a buttocks support portion 31 and a trunk support portion 32 connected to each other. In this embodiment, the child support 3 is integrally formed. The side of the buttocks support portion 31 away from the trunk support portion 32 is connected to the waist belt 1, and the side of the trunk support portion 32 away from the buttocks support portion 31 is connected to the shoulder belt 2.

[0062] It is worth noting that the depth direction of the child support part 3 described in this article specifically refers to the direction from the side where the child support part 3 is connected to the waist belt 1 to the side where the child support part 3 is connected to the shoulder belt 2, that is, the direction from the lower side to the upper side or from the upper side to the lower side of the child support part 3.

[0063] Furthermore, if Figures 1 to 3 As shown, the infant carrier also includes a connector 4 connected to the waist belt 1 and the shoulder belt 2. A storage space for accommodating infants is formed between the connector 4 and the child support 3. The connector 4 includes a first connector 41 and a second connector 42, and the first connector 41 is a substantially rectangular piece of cloth. There are two first connectors 41, and the two first connectors 41 are arranged at intervals and connected to the corresponding shoulder belts 2. The two ends of the second connector 42 are respectively connected to the two first connectors 41. In one embodiment, the connector 4 may also be an integrated piece of cloth, one side of the connector 4 is connected to the waist belt 1, and the other side of the connector 4 is connected to the shoulder belt 2. In another embodiment, the infant carrier may also not include the connector 4, but the shoulder belt 2 directly extends to the waist belt 1 and is connected to the waist belt 1.

[0064] Reference Figures 1 to 3, the side of the trunk support part 32 away from the hip support part 31, that is, the side of the child support part 3 away from the waist belt 1, is detachably connected to the shoulder belt 2, so that it is convenient for infants to enter and exit the accommodation space. When in use, the waist belt 1 can be first fixed to the waist of the caregiver, and the shoulder belt 2 can be hung on the shoulders of the caregiver. At this time, the connecting member 4 is close to the trunk of the caregiver, and then the infant can be picked up, and the side of the child support part 3 away from the waist belt 1 is connected to the shoulder belt 2, so that the infant can sit in the accommodation space. In the infant carrier of this embodiment, the accommodation space is formed by the connecting member 4 and the child support part 3, which has a good wrapping and protection effect on the infant.

[0065] Furthermore, if Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the infant carrier further includes a leg support 51. In this embodiment, there are two leg supports 51, which are respectively arranged on both sides of the hip support portion 31 in the lateral width direction, that is, on the left and right sides of the hip support portion 31. The hip support portion 31 and the leg support 51 form a seat area 101 for carrying infants. One end of the leg support 51 and one end of the hip support portion 31 are connected to the waist belt 1 and form a first fixed end 511 of the leg support 51 and the hip support portion 31, and the other end of the leg support 51 is connected to the other end of the hip support portion 31 and forms a second fixed end 512 of the leg support 51 and the hip support portion 31. The natural depth dimension L1 of the leg support 51 between the first fixed end 511 and the second fixed end 512 is smaller than the natural depth dimension L2 of the hip support portion 31 between the first fixed end 511 and the second fixed end 512, so that the hip support portion 31 can be switched between the expanded state and the folded state in the depth direction of the child support 3. When the buttocks support part 31 is in an extended state in the depth direction, the seat area 101 has a larger dimension in the depth direction; when the buttocks support part 31 is in a retracted state in the depth direction, the seat area 101 has a smaller dimension in the depth direction. In actual use, when an infant sits in the seat area 101, the buttocks support part 31 is in an extended state due to the infant's own weight; and when the infant is not sitting in the seat area 101, the buttocks support part 31 is in a naturally retracted state.

[0066] It is worth noting that the lateral width direction of the child support 3 described herein specifically refers to the direction from the left side to the right side or the right side to the left side of the child support 3, and the longitudinal depth direction of the child support 3 described herein specifically refers to the direction from the side where the child support 3 is connected to the waist belt 1 to the side where the child support 3 is connected to the shoulder belt 2, that is, the direction from the lower side to the upper side or the upper side to the lower side of the child support 3. The natural longitudinal depth dimension of the leg support 51 between the first fixed end 511 and the second fixed end 512 described herein refers to the actual length of the fabric forming the leg support 51 between the first fixed end 511 and the second fixed end 512 in a non-connected state. The natural longitudinal depth dimension of the hip support portion 31 between the first fixed end 511 and the second fixed end 512 described herein refers to the actual length of the fabric forming the hip support portion 31 between the first fixed end 511 and the second fixed end 512 in a non-connected state.

[0067] In this embodiment, Figures 3 to 5 As shown, the hip support portion 31 is formed by a sheet of fabric. The hip support portion 31 is an axisymmetric figure as a whole, and its axis of symmetry is the longitudinal center line extending along the depth direction of the child support member 3. The hip support portion 31 has a first edge 311 on both sides of the child support member 3 in the transverse width direction, that is, the left and right sides of the hip support portion 31 have a first edge 311. Taking the first edge 311 on one side as an example, the first edge 311 includes an arc segment 3111 and a recessed segment 3112 connected to each other. The arc segment 3111 gradually extends from the first fixed end 511 to the second fixed end 512, deviating from the longitudinal center line of the hip support portion 31. The recessed segment 3112 is connected to the arc segment 3111 and is recessed in the direction close to the longitudinal center line of the hip support portion 31. During the manufacturing process, the hip support portion 31 can be cut out of a roughly rectangular sheet of fabric into the shape of the concave sections 3112 on both sides, then folded into the shape of the arc sections 3111 on both sides, and finally sewn to form the shape with the above-mentioned first edge 311. In this embodiment, the arc section 3111 extends outward, so as to form the widest support dimension away from the first fixed end 511, which is conducive to the widest support area for the hips of the baby when sitting. At the same time, the arc section 3111 forms the smallest support dimension near the first fixed end 511, which is convenient for the leg support member 51 to form support and fixed sewing connection with the waist belt 1. The recessed section 3112 is close to the second fixed end 512. Since the longitudinal lengths of the leg support 51 and the hip support portion 31 are different, the recessed section 3112 is provided to facilitate the fixed connection between the leg support 51 and the hip support portion 31 at the recessed section 3112 through the second fixed end 512. It is also convenient to provide the second opening 103 at the recessed section 3112, which not only ensures the convenience of production, but also makes the overall appearance beautiful.

[0068] Furthermore, the hip support portion 31 is provided with a first connection portion 312 at both sides of the hip support portion 31 in the transverse direction of the child support member 3 near the first edge 311 . The first connection portion 312 is a linear connection portion between the first fixed end 511 and the second fixed end 512 .

[0069] In this embodiment, the two leg support members 51 are both substantially long strips of fabric structure, and the shapes and structures of the two leg support members 51 are substantially the same. Figure 3 and Figure 4 As shown, the leg support 51 has a first support portion 513 and a second support portion 514. The thickness of the first support portion 513 is greater than the thickness of the second support portion 514, and the thickness of the first support portion 513 is greater than the thickness of the child support 3. In this embodiment, the thickness of the first support portion 513 may be greater than the thickness of the second support portion 514, and the thickness of the second support portion 514 may be greater than the thickness of the child support 3. In this way, the thigh support can provide stronger support for the thighs of infants and young children. In this embodiment, the first support portion 513 may be a multi-layer structure, for example, a double-layer fabric filled with hard fillers such as cardboard or elastic fillers such as cotton, so that the first support portion 513 has a greater thickness. Figure 6 As shown, the second support portion 514 covers the back of the hip support portion 31 when the infant carrier is in use to form a wing portion for auxiliary support.

[0070] Specifically, Figure 4 and Figure 6As shown, the leg support 51 includes an outer edge 515 away from the hip support portion 31 and an inner edge 516 close to the hip support portion 31, and the outer edge 515 and the inner edge 516 are respectively straight edges. In this embodiment, since one end of the leg support 51 is connected to the waist belt 1, the outer edge 515 of the leg support 51 can be designed as a straight edge, which is more beautiful and easy to process. The leg support 51 also has a dividing edge 517 located between the outer edge 515 and the inner edge 516. The portion of the leg support 51 located at the outer edge 515 and the dividing edge 517 forms the first support portion 513, and the portion of the leg support 51 located at the inner edge 516 and the dividing edge 517 forms the second support portion 514. In this embodiment, the leg support 51 is a long strip fabric structure sewn from double layers of fabric, and has an arc-shaped dividing edge 517 arranged roughly in the middle along the depth direction of the child support 3. The dividing edge 517 can be a sewing line, thereby dividing the leg support 51 into a first support portion 513 and a second support portion 514. The portion close to the outer edge 515 is the first support portion 513, which is filled with the hard filler or soft filler as described above and has a larger thickness, while the portion close to the outer edge 515 is the second support portion 514, which has no filler and is only a double-layer fabric structure, so it is smaller in thickness. Figure 3 and Figure 4 As shown, due to the arc shape of the boundary edge 517 , the first fixing end 511 is formed by one side of the first supporting portion 513 and one side of the second supporting portion 514 , while the second fixing end 512 is formed by only one side of the second supporting portion 514 .

[0071] Furthermore, if Figure 4 and Figure 6 As shown, the leg support 51 is further provided with a second connection portion 518 that can be connected to the first connection portion 312. It can be understood that the second connection portion 518 is also a linear connection portion located between the first fixed end 511 and the second fixed end 512. In this embodiment, the first connection portion 312 and the second connection portion 518 are connected by sewing. Of course, in other embodiments, the first connection portion 312 and the second connection portion 518 can also be connected by bonding or other methods. In this embodiment, the second connection portion 518 is approximately located in the middle of the leg support 51 and is approximately arranged along the dividing edge 517, that is, the second connection portion 518 is arranged away from the outer edge 515, and is also arranged away from the inner edge 516.

[0072] Furthermore, the first connection portion 312 and the second connection portion 518 may be arranged in a variety of ways, so that the leg support 51 and the hip support portion 31 have different matching conditions.

[0073] For example, in the first embodiment, if Figures 6 to 8As shown, the first connection portion 312 and the second connection portion 518 are both connected to the second fixed end 512 and spaced apart from the first fixed end 511, and the portion of the leg support 51 between the first fixed end 511 and the second connection portion 518 and the portion of the child support 3 between the first fixed end 511 and the first connection portion 312 form a first opening 102, that is, the first opening 102 is formed between the portion of the leg support 51 close to the waist belt 1 and the portion of the hip support portion 31 close to the waist belt 1.

[0074] In the second embodiment, if Fig. 9 and Fig.10 As shown, the first connection part 312 and the second connection part 518 are located between the first fixed end 511 and the second fixed end 512 and are spaced apart from the first fixed end 511 and the second fixed end 512. The portion of the leg support 51 located between the first fixed end 511 and the second connection part 518 and the portion of the hip support part 31 located between the first fixed end 511 and the first connection part 312 form a first opening 102, while the portion of the leg support 51 located between the second fixed end 512 and the second connection part 518 and the portion of the hip support part 31 located between the second fixed end 512 and the first connection part 312 form a second opening 103. That is, the first opening 102 is formed between the portion of the leg support 51 close to the waist belt 1 and the portion of the hip support part 31 close to the waist belt 1, while the second opening 103 is formed between the portion of the leg support 51 away from the waist belt 1 and the corresponding portion of the hip support part 31 away from the waist belt 1.

[0075] In a third embodiment, if Fig.11 As shown, the first connection portion 312 and the second connection portion 518 are both connected to the first fixed end 511 and spaced apart from the second fixed end 512, and a portion of the leg support 51 between the second fixed end 512 and the second connection portion 518 and a portion of the hip support portion 31 between the second fixed end 512 and the first connection portion 312 form a second opening 103, that is, a second opening 103 is formed between a portion of the leg support 51 away from the waist belt 1 and a corresponding portion of the hip support portion 31 away from the waist belt 1.

[0076] In the fourth embodiment, Fig.12 As shown, the first connection portion 312 and the second connection portion 518 both extend continuously from the first fixed end 511 to the second fixed end 512 , that is, the leg support 51 and the hip support portion 31 are completely sewn together, and no opening is formed between the leg support 51 and the hip support portion 31 .

[0077] In the above embodiment, if the first opening 102 or the second opening 103 is formed between the leg supporting member 51 and the hip supporting portion 31 , it is beneficial to the flexible connection and movable adjustment between the leg supporting member 51 and the first connecting portion 312 .

[0078] Furthermore, if Figure 5 As shown, both sides of the hip support part 31 in the horizontal width direction have first edges 311, and the distance W1 between the first fixed ends 511 of the two leg support members 51 located on both sides of the hip support part 31 in the horizontal width direction is smaller than the maximum horizontal width W2 between the two first edges 311 of the hip support part 31. In this way, when the infant is sitting, his buttocks can be seated in the widest support area, especially when the baby is sitting facing the user, the baby's thighs can be supported in the narrower area close to the waist belt, so that the thighs can form ergonomic M-shaped legs.

[0079] It is worth noting that the maximum transverse width between the two first edges 311 of the hip support portion 31 described herein refers to the dimension of the fabric forming the hip support portion 31 between the two first edges 311 in a connected state.

[0080] Furthermore, if Figure 5 As shown, the hip support portion 31 has at least one linear folding portion 313, and the linear folding portion 313 extends roughly along the depth direction of the child support member 3. Specifically, the linear folding portion 313 is formed by folding and sewing the hip support portion 31 along the transverse width direction. In this embodiment, the hip support portion 31 has two linear folding portions 313 arranged at intervals, and the two linear folding portions 313 are both located at the hip support portion 31 near the waist belt 1. The provision of the linear folding portion 313 also helps the hip support portion 31 to form a pocket-shaped structure with a concave middle.

[0081] Further, at least one position, such as Figures 5 to 7 As shown, the transverse width distance between the two second connection parts 518 of the two leg support members 51 is smaller than the natural transverse width dimension between the two first connection parts 312 of the hip support member 31. The natural transverse width dimension between the two first connection parts 312 of the hip support member 31 described herein refers to the actual length of the fabric forming the hip support member 31 between the two first edges 311 in the non-connected state. In this way, in the transverse width direction, the hip support member 31 is in a wrinkled state at at least one position. In this way, the hip support member 31 can be switched between a folded state and an expanded state in the transverse width direction of the child support member 3.

[0082] Specifically, Figure 6 As shown in FIG. 1 , when the infant carrier is not in use, the hip support portion 31 is in a retracted state in the lateral width direction of the child support member 3 . Figure 7As shown, when the infant carrier is in use, that is, when the infant sits in the infant carrier, the hip support portion 31 is in an expanded state in the lateral width direction of the child support member 3, and the expansion degree of the hip support portion 31 can be adaptively adjusted according to the different body shapes of the infant. Specifically, when a larger infant sits in the infant carrier, the infant can press down the seat area 101 with his or her own greater weight, so that the hip support part 31 will be stretched downward and be in an expanded state. The seat area 101 is larger in the depth direction. At the same time, due to the stretching deformation of the hip support part 31, the gravity of the infant generates a greater force F on the connection parts between the two sides of the hip support part 31 and the corresponding two leg support parts 51, so that the hip support part 31 is stretched to a greater extent in the horizontal width direction of the child support part 3 and has a greater degree of expansion. The two leg support parts 51 expand in the direction away from each other, and at the same time, combined with the hip support part 31 being pressed downward to form a support, the seat area 101 is enlarged, which is suitable for larger infants to sit on, and the infant's legs can form ergonomic M-shaped legs. When a smaller infant sits in the infant carrier, the hip support portion 31 will not be stretched downward too much due to the smaller gravity and smaller hip size of the infant. Therefore, the hip support portion 31 is stretched to a smaller extent in the lateral width direction of the child support 3 and has a smaller expansion degree. The seat area 101 is smaller in the depth direction. At the same time, the force F exerted by the infant's gravity on the two sides of the hip support portion 31 and the connection parts between the two corresponding leg support members 51 is smaller, so that the hip support portion 31 has a smaller expansion degree in the lateral width direction of the child support 3. The two leg support members 51 are relatively close, so that the seat area 101 is reduced, which is suitable for smaller infants to sit on, so that the infant's legs can form ergonomic M-shaped legs.

[0083] Of course, in other embodiments, the first connection portion 312 and the second connection portion 518 may not be directly connected. Fig.14 As shown, the hip support portion 31 and the leg support member 51 are elastically connected. Specifically, an elastic member 52 may be connected between the hip support portion 31 and the leg support member 51, and the elastic member 52 may be switched between an extended state and a non-extended state. In this embodiment, the elastic member 52 is a whole piece of elastic member. In other embodiments, the elastic member 52 may also be at least one strip of elastic band. Both sides or both ends of the elastic member 52 in the transverse width direction of the child support member 3 are respectively connected to the first connection portion 312 and the second connection portion 518, which can provide sufficient elastic support for the seat area 101.

[0084] Thus, when the infant carrier is not in use, the elastic member 52 is in a non-extended state. When the infant carrier is in use, that is, when the infant is riding on the infant carrier, the elastic member 52 is in an extended state, and the extension degree of the elastic member 52 can be adaptively adjusted according to the different body shapes of the infant. When the infant carrier carries a larger infant, the elastic member 52 will be in a larger extension under the action of the larger gravity and the larger hip size of the infant, so that the size of the horizontal width direction of the seat area 101 is increased, so that it is suitable for the larger infant to ride, so that the infant's legs can form an ergonomic "M"-shaped leg. When the infant carrier carries a smaller infant, because the infant has a smaller gravity and a smaller hip size, the elastic member 52 will be in a smaller extension under the action of the smaller gravity and the smaller hip size of the infant, so that it is suitable for the smaller infant to ride, so that the infant's legs can form an ergonomic "M"-shaped leg.

[0085] On the other hand, the present invention also provides an infant carrier, which, like the infant carrier in the above-mentioned embodiment, has a leg support 51, a waist belt 1, a shoulder belt 2, and a child support 3 connected to the waist belt 1 and the shoulder belt 2, respectively. The portion of the child support 3 close to the waist belt 1 also forms a hip support portion 31. Two leg supports 51 are arranged on both sides of the hip support portion 31 in the transverse width direction. One end of the leg support 51 and one end of the hip support portion 31 are connected to the waist belt 1 and form a first fixed end 511 between the leg support 51 and the hip support portion 31, and the other end of the leg support 51 is connected to the other end of the hip support portion 31 and forms a second fixed end 512 between the leg support 51 and the hip support portion 31. Both sides of the hip support portion 31 in the transverse width direction have a first edge 311, and the distance W1 between the first fixed ends 511 of the two leg supports 51 located on both sides of the hip support portion 31 in the transverse width direction is less than the maximum transverse width dimension W2 between the two first edges 311. In this way, it can be ensured that the hip support part 31 can form a concave pocket shape when the infant sits. Specifically, when the infant sits in the infant carrier, the weight of the infant presses down the seat area 101, so that the two leg support members 51 located on both sides of the hip support part 31 are separated from each other. At the same time, the hip support part 31 is pressed down to form a support, and the seat area 101 is enlarged, so that the infant can form an ergonomic M-shaped leg.

[0086] In another aspect, the present invention provides an infant carrier, which, like the infant carrier in the above embodiment, has a leg support 51, a waist belt 1, a shoulder belt 2, and a child support 3 connected to the waist belt 1 and the shoulder belt 2, respectively. One end of the leg support 51 and one end of the hip support 31 are connected to the waist belt 1 and form a first fixed end 511 of the leg support 51 and the hip support 31, and the other end of the leg support 51 is connected to the other end of the hip support 31 and forms a second fixed end 512 of the leg support 51 and the hip support 31. At at least one position, the lateral width distance between the two second connection parts 518 of the two leg supports 51 is smaller than the natural lateral width dimension between the two first connection parts 312 of the hip support 31. In this way, the hip support 31 can be switched between a folded state and an unfolded state in the lateral width direction of the child support 3.

[0087] Specifically, when the infant carrier is not in use, the hip support portion 31 is in a retracted state in the lateral width direction of the child support 3. When the infant carrier is in use, that is, when the infant is sitting in the infant carrier, the hip support portion 31 is in an expanded state in the lateral width direction of the child support 3, and the expansion degree of the hip support portion 31 can be adaptively adjusted according to the different body shapes of the infant. Specifically, when a larger infant sits in the infant carrier, the infant can press down the seat area 101 with his or her own greater weight, so that the hip support part 31 will be stretched downward and be in an expanded state. The seat area 101 is larger in the depth direction. At the same time, due to the stretching deformation of the hip support part 31, the gravity of the infant generates a greater force F on the connection parts between the two sides of the hip support part 31 and the corresponding two leg support parts 51, so that the hip support part 31 is stretched to a greater extent in the horizontal width direction of the child support part 3 and has a greater degree of expansion. The two leg support parts 51 expand in the direction away from each other, and at the same time, combined with the hip support part 31 being pressed downward to form a support, the seat area 101 is enlarged, which is suitable for larger infants to sit on, and the infant's legs can form ergonomic M-shaped legs. When a smaller infant sits in the infant carrier, the hip support portion 31 will not be stretched downward too much due to the smaller gravity and smaller hip size of the infant. Therefore, the hip support portion 31 is stretched to a smaller extent in the lateral width direction of the child support 3 and has a smaller expansion degree. The seat area 101 is smaller in the depth direction. At the same time, the force F exerted by the infant's gravity on the two sides of the hip support portion 31 and the connection parts between the two corresponding leg support members 51 is smaller, so that the hip support portion 31 has a smaller expansion degree in the lateral width direction of the child support 3. The two leg support members 51 are relatively close, so that the seat area 101 is reduced, which is suitable for smaller infants to sit on, so that the infant's legs can form ergonomic M-shaped legs.

[0088] The above-mentioned infant carrier has at least the following technical effects:

[0089] In the above-mentioned infant carrier, the waist belt 1 and the shoulder belt 2 are respectively connected to both sides of the child support 3 in the longitudinal direction, and the part of the child support 3 close to the waist belt 1 forms the hip support part 31. The leg support 51 is arranged on one side of the hip support part 31 in the transverse width direction, and the two ends of the leg support 51 are respectively connected to one end of the hip support part 31 as the first fixed end 511 and the second fixed end 512, and the natural longitudinal depth dimension of the leg support 51 between the first fixed end 511 and the second fixed end 512 is smaller than the natural longitudinal depth dimension of the hip support part 31 between the first fixed end 511 and the second fixed end 512, so that the hip support part 31 can be switched between the expanded state and the folded state in the longitudinal direction of the child support 3. In this way, when the infant carrier carries a large infant, the hip support part 31 will be stretched downward under the gravity of the infant and be in the expanded state, so that the seat area 101 has a larger dimension in the longitudinal direction to adapt to the larger size of the infant. When the infant carrier carries a small infant, the hip support portion 31 will be in a contracted state due to the small weight of the infant, so that the seat area 101 has a smaller size in the depth direction to adapt to the smaller size of the infant. In this way, the infant carrier can adaptively adjust the size of its seat area 101 according to the size of the infant, and has a simple structure and is easy to use.

[0090] In addition to the above embodiments, the present application also provides another infant carrier, Fig.15 and Fig.16, the infant carrier has the same leg support 51, waist belt 1, shoulder belt 2 and child support 3 connected to waist belt 1 and shoulder belt 2 as the infant carrier in the above embodiment. The part of child support 3 close to waist belt 1 also forms hip support part 31. Two leg support 51 are arranged on both sides of hip support part 31 in the horizontal width direction. The leg support 51 includes a first connection end 510 and a second connection end 519 arranged in the depth direction, and the leg support 51 is connected to hip support part 31 through the first connection end 510, and is pivotally connected to child support part 3 through the second connection end 519. In this embodiment, specifically, the leg support 51 is fixedly connected to hip support part 31 through the first connection end 510, therefore, the first connection end 510 is also referred to as fixed end 510, and the second connection end 519 is also referred to as pivot end 519. Of course, in other embodiments, the leg support 51 can also be non-fixedly connected to hip support part 31 through the first connection end 510. In this way, when the infant is not sitting in the infant carrier, the leg support 51 of the infant carrier is initially in a folded state; when the infant is sitting in the infant carrier, the hip support and the leg support are squeezed by the infant's own weight, and one end of the leg support 51 can be pivoted relative to the hip support 31, so that the two leg support 51 can adaptively expand in a direction away from each other, so that the leg support is in an expanded state, thereby providing good support for the infant's thighs and achieving a favorable sitting posture of M-shaped legs. In addition, since infants of different ages have different weights, the degree of squeezing the hip support and the leg support is different. Therefore, when infants of different ages sit in the infant carrier, the effective seat width presented by the infant carrier is different. Of course, the user of the infant carrier can also manually adjust the degree of expansion of the two leg support 51 in the direction away from each other to adapt to other possible usage scenarios.

[0091] Preferably, two leg supports 51 are provided, and the leg supports 51 are provided on both sides of the child support 3 along the horizontal width direction, and the two leg supports 51 expand in opposite directions relative to the child support 3. Specifically, when an infant is placed on the infant carrier, the two leg supports 51 are expanded in opposite directions relative to the child support 3. Each leg support 51 is respectively provided with a fixed end 510 and a pivot end 519. The two connection points between the child support 3 and the fixed end 510 are respectively located at the positions of the horizontal width sides of the child support 3, and the two support points between the child support 3 and the pivot end 519 are also respectively located at the positions of the horizontal width sides of the child support 3.

[0092] In some embodiments, reference Fig.18A, when the pivot end 519 of the leg support 51 is not yet connected to the child support 3, the distance between the fixed end 510 of the leg support 51 and the pivot end 519 along the depth direction is smaller than the distance between the connection with the fixed end 510 and the connection with the pivot end 519 on the child support 3. In this way, when the infant carrier is not used, that is, when the infant carrier is in the initial state, the hip support part 31 is more likely to be in a wrinkled state in the depth direction, and then it can easily form a pocket-shaped structure, thereby improving the wrapping degree and support performance of the infant's hips.

[0093] In some embodiments, reference Fig.15 , Fig.18A and Fig. 18C ,from Fig.18A From the perspective of , in the horizontal width direction, both sides of the child support member 3 form an inward concave position 310, and the connection point between the child support member 3 and the pivot end 519 of the leg support member 51 is slightly higher than the position where the inward concave position 310 is most concave. In this way, in the depth direction, the position near the middle of the buttocks support part 31 has an inwardly converging structure, which also helps to form a pocket-shaped structure when the infant is sitting, so as to further improve the wrapping degree and support performance of the infant's buttocks.

[0094] In some embodiments, the leg support 51 has a connecting section 53 and a supporting section 54, and the supporting section 54 is located on the lateral outer side of the connecting section 53. Fig.18A and Fig. 18C, similar to the above-mentioned embodiment, the leg support 51 includes an outer edge 515 away from the hip support portion 31 and an inner edge 516 close to the hip support portion 31, and the leg support 51 also has a dividing edge 517 between the outer edge 515 and the inner edge 516, and the dividing edge 517 can be a sewing line, so as to separate the connecting section 53 and the supporting section 54. In this embodiment, the leg support 51 has an arc-shaped dividing edge 517 arranged roughly along the longitudinal direction of the child support 3 in the middle. Among them, the part close to the outer edge 515 is the supporting section 54, which is filled with hard fillers or soft fillers, and the part close to the inner edge 516 is the connecting section 53, which has no fillers. The connecting section 53 is, for example, a soft fabric, so that the connecting section 53 can shrink to form folds, thereby changing its effective size in the transverse width direction, that is, the transverse width size. It can be understood that, on the one hand, in the initial state of the infant carrier, the connecting section 53 is in a wrinkled state, so that the effective transverse width of the leg support is smaller, making the infant carrier more aesthetically pleasing; on the other hand, when the infant is riding in the infant carrier, since the connecting section 53 can be unfolded in the transverse width direction, the support section can have a certain degree of pivotal freedom. With the cooperation of the pivot end 519, the degree of adaptability of the two leg supports 51 to expand away from each other is further improved, so that infants of different ages (weights) can achieve a favorable sitting posture of M-shaped legs.

[0095] refer to Fig.17A and Fig. 17B . Fig.17A It is a schematic diagram of the leg support 51 in a folded state. At this time, the leg support 51 is less expanded, and only the first support section 541 and part of the second support section 542 extend in the horizontal width direction to a degree not blocked by the hip support part 31. Fig. 17B It is a schematic diagram of the leg support 51 in the unfolded state. At this time, the leg support 51 is expanded to a greater extent, and the first support section 541, the second support section 542 and part of the connecting section 53 all extend in the horizontal width direction to a degree that they are not blocked by the hip support part 31.

[0096] Preferably, in some embodiments, the thickness of the support section 54 is greater than the thickness of the connecting section 53. The thicker support section 54 is beneficial to supporting the thighs of infants and young children, thereby achieving a favorable sitting posture of M-shaped legs. The thinner connecting section 53 is beneficial to the expansion and contraction of the connecting section 53, thereby achieving the conversion of the leg support 51 between the expanded state and the folded state.

[0097] Preferably, in some embodiments, the support segment 54 of the leg support 51 includes a first support segment 541 and a second support segment 542. Fig.18A , Fig. 18C and Fig.18DThe leg support 51 is provided with a third connection portion 5422 and a fourth connection portion 5423, both of which are linear connection portions located between the pivot end 519 and the fixed end 510, and the third connection portion 5422 and the fourth connection portion 5423 are arranged opposite to each other. The second support segment 542 is connected to the connection segment 53 through the third connection portion 5422, and the second support segment 542 is connected to the first support segment 541 through the fourth connection portion 5423, so that the first support segment 541, the second support segment 542 and the connection segment 53 are sequentially connected in the transverse width direction of the hip support portion 31. Specifically, for the leg support 51, the first support segment 541 is located at the outermost side in the transverse width direction, the connection segment 53 is located at the innermost side in the transverse width direction, and the second support segment 542 is located between the two.

[0098] Further, refer to Fig.18A , the natural dimension of the connecting section 53 in the lateral width direction will be greater than the distance between the inner edge 516 and the third connecting portion 5422. The natural dimension here refers to the dimension of the connecting section 53 when it is not connected to the child support member 3 and the leg support member 51 and is naturally unfolded. Fig.18A and 18D As shown, the connecting section 53 is wrinkled in the transverse direction so as to stretch and form a pocket-like structure when an infant sits on it.

[0099] refer to Fig.18D In this embodiment, the thickness of the first support section 541 is set to be greater than the thickness of the second support section 542. Specifically, the thickness of the first support section 54 is set to be greater than the thickness of the second support section 542, which can be either that the filling amount of the soft filler in the first support section 541 is greater than the filling amount of the soft filler in the second support section 542, or that the thickness of the hard filler in the first support section 541 itself is greater than the thickness of the hard filler in the second support section 542, and other situations in which the thickness of the first support section 541 can be greater than the thickness of the second support section 542, which are not limited in this application. It can be understood that when an infant sits on the infant carrier in this embodiment, since the thickness of the first support section 541 is greater than the thickness of the second support section 542, the first support section 541 is not easy to fold, and then the first support section 541 can play a more obvious supporting role relative to the second support section 542, and the overall structure of the leg support is more reasonable, and it is easier to form a favorable sitting posture of M-shaped legs.

[0100] In some embodiments, the thickness of the second support segment 542 is greater than the thickness of the connecting segment 53. In this setting, the thickness of the first support segment 541 is greater than the thickness of the second support segment 542, and the thickness of the second support segment 542 is greater than the thickness of the connecting segment 53. It can be understood that the thickness of the leg support 51 gradually increases in the direction toward the outer side of the transverse width direction of the infant carrier, which is particularly beneficial for forming an M-shaped leg sitting posture. At the same time, since the thickness of the connecting segment 53 is the thinnest, the connecting segment 53 is easier to expand and shrink in the transverse width direction. Preferably, the leg support 51 is provided with a first pivot hole 551, and the first pivot hole 551 can be used for riveting a pivot member such as a rivet, so that the leg support 51 is pivoted to the child support 3. In this embodiment, the first pivot hole 551 is provided on the support segment 54 of the leg support 51 instead of the connecting segment 53 because the thickness of the support segment 54 is thicker than that of the connecting segment 53, so as to provide the necessary rigidity for the connection and pivoting of the pivot end 519. Preferably, the first pivot hole 551 is arranged on the second support section 55. Compared with the first support section 54 and the connecting section 53, the thickness of the second support section 55 is moderate, which can provide necessary rigidity for the connection and pivoting of the pivot end 519 and avoid the pivot end 519 from rotating smoothly.

[0101] Optionally, refer to Fig.18A and Fig.18B In some embodiments, the child support 3 includes a body layer 33 as a body part. On the inner surface of the infant carrier, that is, the side of the infant carrier that contacts the infant when the infant is riding, a reinforcing layer 34 is connected to the body layer 33, and the reinforcing layer 34 covers a part of the body layer 33. In this embodiment, the reinforcing layer 34 is sutured and connected to the body layer 33. In other embodiments, the present application does not limit the connection form of the reinforcing layer 34 and the body layer 33. On the inner surface of the infant carrier, the area of ​​the body layer 33 not covered by the reinforcing layer 34 forms a thinning area 35. The thinning area 35 is located in the middle area of ​​the child support 3 in the horizontal width direction, and extends along the depth direction of the child support 3, so that the thinning area 35 covers most of the trunk and buttocks of the infant riding on the infant carrier, thereby providing better heat dissipation and air permeability. Preferably, the body layer 33 is formed of a breathable fabric, thereby optimizing the heat dissipation and air permeability of the thinning area 35. Preferably, the reinforcing layer 34 covers at least the shoulder strap area of ​​the child support 3 and the areas on both sides of the hip support 31, so as to provide the necessary strength for the actual use of the infant carrier. In some embodiments, the inner edge 516 of the leg support 51 extends parallel to the adjacent edge of the thinned area 35. Optionally, the connection point of the child support 3 with the pivotal ends of the two leg supports 51 is located in the area of ​​the reinforcing layer 34 and on both sides of the thinned area 35.

[0102] In some embodiments, the child support 3 and the leg support 51 are connected to the waist belt 1 in a detachable manner. Fig.16 Specifically, the child support 3 is provided with a waist belt connecting side 36 in the depth direction, and corresponding connecting parts (not shown in the figure) are provided on the waist belt connecting side 36 and the waist belt 1, and the child support 3 and the leg support 51 are detachably connected to the waist belt 1 at the waist belt connecting side 36. Of course, the child support 3 and the leg support 51 can also be fixedly connected to the waist belt 1.

[0103] like Fig.15 and Fig.18A As shown, the leg support 51 is connected to the inner surface of the child support 3. Specifically, the connecting section 53 of the leg support 51 is connected to the inner surface of the child support 3 near the transverse width edge of the hip support portion 31, the fixed end 510 of the leg support 51 is connected to the waist belt connection side 36 on the inner surface of the child support 3, and the pivot end 519 of the leg support 51 is also connected to the inner surface of the child support 3. Preferably, at the fixed end 510 of the leg support 51, or at the waist belt connection side 36 of the child support 3, the outer edge 515 of the leg support 51 is staggered from the outer edge of the corresponding hip support portion 31 in the transverse width direction. Specifically, in the transverse width direction, the outer edge 515 of the leg support 51 is located outside the outer edge 315 of the corresponding hip support portion. That is, as shown in FIG. Fig. 18C As shown, from the outside of the child support 3, in the lateral width direction, the fixed end 510 of the leg support 51 is partially exposed outside the hip support portion 31. Preferably, at the fixed end 510 of the leg support 51, in the lateral width direction, the outer edge 315 of the hip support portion is located between the outer edge 515 of the leg support 51 and the third connection portion 5422. In this way, in the initial state of the infant carrier (i.e., the unused state), a large part of the leg support 51 can be hidden in the child support 31, thereby improving the overall aesthetics of the infant carrier, and at the same time, the unfolding and folding functions of the leg support 51 will not be affected.

[0104] In some embodiments, the first support segment 541 is formed with an outer protrusion 5150. Fig.18A and Fig. 18C , the outer protrusion 5150 protrudes in a direction away from the second support section 542. It can be understood that when the pivot end 519 of the leg support member 51 and the hip support member 31 are in a pivoted state, the outer protrusion 5150 is roughly aligned with the inner concave portion 310 of the hip support member 31 in the transverse width direction. In this way, the support strength of the child support member 3 for the infant in the transverse width direction corresponding to the inner concave portion 310 can be strengthened.

[0105] In some embodiments, along the depth direction, the first end of the connecting segment 53, the supporting segment 54 and the child support 3 form a first opening 55, and the second end of the connecting segment 53, the supporting segment 54 and the child support 3 form a second opening 56. Fig. 20 In this embodiment, the first end is the lower end of the connecting section 53 in the depth direction, and the second end is the upper end of the connecting section 53 in the depth direction. Fig.18A , the first opening 55 is formed by the lower end of the connecting section 53, the supporting section 54 and the child supporting member 3, but at this time, since the pivot end 519 is not connected to the child supporting member 3, the second opening 56 is not formed. Fig. 20 When the pivot end 519 is connected to the child connector 3, the second opening 56 is formed by the upper end of the connecting section 53, the supporting section 54 and the child support 3. Since the second opening 56 is blocked by the covering portion 7, Fig. 20 The second opening 56 is shown by a dotted line, which only indicates the approximate position of the second opening 56 and does not limit the specific position and shape of the second opening 56. By forming the first opening 55 and the second opening 56, the connecting section 53 is easier to unfold or collapse, which can improve the use experience.

[0106] In some embodiments, the infant carrier further comprises a pivot assembly 6. Fig.19A In one implementation of the infant carrier of the present embodiment, the pivot assembly 6 includes a first pivot member 61 and a second pivot member 62, wherein the structure of the first pivot member 61 is similar to a rivet, and includes a pivot shaft 611 and a first stop member 612 fixedly connected to one end of the pivot shaft 611, and the first stop member 612 is approximately disc-shaped. The second pivot member 62 includes a second stop member 621 approximately disc-shaped and a fastening portion 622 protruding from the circular outer surface of the second stop member 621. The pivot shaft 611 is provided with a fastening groove (not shown in the figure), and the fastening portion 622 is inserted into the fastening groove. Preferably, the fastening portion 622 generates friction with the groove wall of the fastening groove without relative sliding, so that the first pivot member 61 and the second pivot member 62 are fixedly connected. In this embodiment, the second support section 55 is provided with a first pivot hole 551, the hip support portion 31 is provided with a second pivot hole 314, and the pivot shaft 611 is simultaneously provided through the first pivot hole 551 and the second pivot hole 314, and is clearance-matched with the first pivot hole 551 and the second pivot hole 314, so that the second support section 55 and the hip support portion 31 can rotate relative to each other around the pivot shaft 611, that is, the leg support member 51 is pivotally connected to the hip support portion 31. It can be understood that the first stopper 612 and the second stopper 621 can prevent the second support section 55 and the hip support portion from being separated from each other, and can effectively maintain the active riveting state of the second support section 55 and the hip support portion.

[0107] In another implementation of the infant carrier of this embodiment, the fastening portion 622 is not integrally provided with the second stopper 621. Fig.19B As shown, the second stopper 621 is provided with a countersunk hole, and the fastening portion 622 is provided with an external thread, and the fastening portion 622 can pass through the countersunk hole and cooperate with the inner wall thread of the fastening groove. It can be understood that tightening the fastening portion 622 can stop the second stopper 621 against the pivot shaft 611, and can also achieve the effect of fixing the first pivot member 61 and the second pivot member 62.

[0108] In some embodiments, the infant carrier is further provided with a covering portion 7, which is located on a side surface of the leg support 51 for infants to sit on, that is, the inner surface of the child support 3. Fig.15 and Fig. 20 The covering portion 7 is connected to the region of the pivot end 519 of the leg support 51, and the covering portion 7 is also formed of fabric. Specifically, the covering portion 7 covers the connecting section 53, the second supporting section 542, and a portion of the top of the supporting section 54. It can be understood that the pivot assembly 6 and the first pivot hole 551 are also covered by the covering portion 7. Therefore, when an infant rides on the infant carrier, the infant's skin is protected by the covering portion 7 and does not come into direct contact with the pivot assembly 6, thereby preventing the pivot assembly 6 from causing discomfort or even skin abrasion to the baby riding on the infant carrier.

[0109] Optionally, the covering portion 7 is in a non-completely connected state with the leg support 51. The covering portion 7 is sewn to the first support section 54 and the connecting section 53, but the covering portion 7 is not sewn to the second support section 55. Since the covering portion 7 and the second support section 55 are both formed of fabric and have plasticity, the covering portion 7 and the second support section 55 are stretched in directions away from each other, so that a pocket-like structure can be formed between the covering portion 7 and the leg support 51. In this way, when installing the pivot assembly 6, the first pivot 61 can be placed in the pocket structure, and then the first pivot 61 and the second pivot 62 are connected. Therefore, the pocket structure formed by the covering portion 7 and the leg support is convenient for installing the pivot assembly 6 and sewing, which reduces the difficulty of operation. Of course, the pivot assembly 6 can also be installed first, and then the covering portion 7 can be sewn to the pivot end of the leg support. The covering portion 7 can also be completely sewn to the leg support without forming a pocket-like structure.

[0110] In an exemplary embodiment, reference Fig.18A and Fig. 18C, the pivot end 519 is connected to a specific connection point of the child support member 3 on the child support member 3, that is, the location of the second pivot hole 314 of the present embodiment. Compared with the connection point of the pivot end 519 and the child support member 3, the connection point of the fixed end 510 and the waist belt connection side 36 is located on the outside in the transverse width direction. In other words, compared with the connection point of the fixed end 510 and the waist belt connection side 36, the connection point of the pivot end 519 and the child support member 3 is closer to the middle of the child support member 3 in the transverse width direction. In this way, when an infant sits on the infant carrier, it helps to make the infant's legs in an M-shaped posture, thereby improving the stability when sitting. The pivotable range of the leg support member 51 near the pivot end 519 is greater than the pivotable range of the leg support member 51 near the fixed end 510.

[0111] In some embodiments, Fig.21 and Fig. 22 As shown, the infant carrier also includes a height adjustment member 40, which is a fabric connected to the front side of the shoulder strap 2 along the horizontal width direction. The waist belt connection side 36 of the child support member 3 can be detachably connected to the waist belt 1 or the height adjustment member 40 so that the hip support part 31 of the child support member 3 is at different heights, thereby adjusting the different sitting heights of infants to adapt to infants of different body shapes. The position of the waist belt connection side 36 is as shown in FIG. Fig.18A and Fig. 18C shown.

[0112] refer to Fig.15 and Fig.16 , taking one of the shoulder straps 2 as an example to describe the connection relationship of the shoulder straps 2. The bottom end of the shoulder strap 2 in the depth direction is the first end, and the first end is fixedly connected to the waist belt 1. Fig.21 and Fig. 22 When using the infant carrier, if Fig. 22 As shown, the shoulder strap 2 passes through the user's shoulders and around the user's back, and then connects to the front after passing around the shoulders. The shoulder strap 2 also has a second end, and the second end of the shoulder strap 2 has a bifurcated structure, forming a first connecting strap 21 and a second connecting strap 22, and the first connecting strap 21 is fixedly connected to the front of the shoulder strap 2. The second connecting strap 22 is detachably connected to the child support 3. In this embodiment, the second connecting strap 22 is provided with a first connecting structure 221, and the trunk support portion 32 is provided with a second connecting structure 321. The second connecting structure 321 cooperates with the first connecting structure 221, so that the second connecting strap 22 can be detachably connected to the child support 3. In some embodiments, the first connecting structure 221 and the second connecting structure 321 are male and female buckles of magnetic buckles. Of course, the first connecting structure 221 and the second connecting structure 321 can also be other forms of connecting structures.

[0113] In some embodiments, the infant carrier is further provided with a leg opening restriction component 8. The leg opening restriction component 8 includes a first fixing portion 81 provided on the first connecting belt 21 and a second fixing portion 82 provided on the second connecting belt 22. Fig. 22 As shown, when the first fixing portion 81 and the second fixing portion 82 are not connected, the opening formed by the leg support 51, the trunk support portion 32 and the user's body is relatively large in the lateral width direction. Fig.21 As shown, when the first fixing portion 81 and the second fixing portion 82 form a connection relationship, the distance between the front portion of the shoulder strap 2 and the child support 3 can be shortened, thereby reducing the opening formed by the leg support 51, the trunk support portion 32 and the user's body, thereby improving the wrapping degree and support performance of the infant's legs.

[0114] In this embodiment, the first fixing portion 81 is a button, and the second fixing portion 82 is a button hole. In other embodiments, the first fixing portion 81 and the second fixing portion 82 may also be other forms of connecting components, which is not limited in the present application.

[0115] In particular, other embodiments of the present application provide another infant carrier, which is different from the above-mentioned infant carrier in that the leg support 51 of the infant carrier is respectively provided with a first connection end and a second connection end in the depth direction, and the leg support 51 is pivotally connected to the hip support part 31 through the first connection end, and is pivotally connected to the child support 3 through the second connection end. In this way, when the infant sits on the infant carrier, the two leg support members 51 can also adaptively expand in a direction away from each other, and the degree of adaptive expansion is higher, so that the leg support members are in an unfolded state, thereby achieving good support for the infant's thighs and achieving a favorable sitting posture of M-shaped legs. The other structures and features of this embodiment are the same as those of the above-mentioned embodiment.

[0116] The above aspects and technical features of each embodiment of the present invention can be arbitrarily combined. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0117] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
