[0211] (I) First Aspect of the Application

[0212] According to a first embodiment of the present disclosure, a baby carrier is provided. Figure 1 to Figure 2 As shown, the infant carrier includes a waist belt A1, a shoulder belt A2, and a child support piece A3 connected to the waist belt A1 and the shoulder belt A2, respectively. The shoulder belt A2 is arranged roughly along the depth direction of the child support piece A3. One side of the child support piece A3 is connected to the waist belt A1, and the side of the child support piece A3 away from the waist belt A1 is detachably or non-detachably connected to the shoulder belt A2. That is, the upper side of the child support piece A3 is connected to the shoulder belt A2, and the lower side of the child support piece A3 is connected to the waist belt A1. In this embodiment, the upper side of the child support piece A3 is detachably connected to the shoulder belt A2 via a connector (such as a buckle). In other embodiments, the child support piece A3 may be fixedly connected to the shoulder belt A2. This application does not limit the specific connection method between the child support piece A3 and the shoulder belt A2. Refer to Figure 1 to Figure 2The child support A3 includes a buttocks support portion A31 and a trunk support portion A32 connected to each other. In this embodiment, the child support A3 is integrally formed. The side of the buttocks support portion A31 away from the trunk support portion A32 is connected to the waist belt A1, and the side of the trunk support portion A32 away from the buttocks support portion A31 is connected to the shoulder belt A2.

[0213] It is worth noting that the depth direction of the child support part A3 described in the previous paragraph and below specifically refers to the direction from the side where the child support part A3 is connected to the waist belt A1 to the side where the child support part A3 is connected to the shoulder belt A2, that is, the direction from the lower side to the upper side or the upper side to the lower side of the child support part A3.

[0214] Furthermore, if Figure 1 , Figure 2 and 5 As shown, the infant carrier also includes a connection portion A4 connected to the waist belt A1 and the shoulder belt A2. A storage space for accommodating infants is formed between the connection portion A4 and the child support A3. Among them, the connection portion A4 includes a first connection portion A41 and a second connection portion A42, and the first connection portion A41 is a substantially rectangular piece of cloth. The number of the first connection portions A41 is two, and the two first connection portions A41 are arranged at intervals and connected to the corresponding shoulder belts A2. One side of the second connection portion A42 is respectively connected to the two second connection portions A42, and the other side of the second connection portion A42 is respectively connected to the two shoulder belts A2. In one embodiment, the connection portion A4 can also be an integrated piece of cloth, one side of the connection portion A4 is connected to the waist belt A1, and the other side of the connection portion A4 is connected to the shoulder belt A2. In another embodiment, the infant carrier may also not include the connection portion A4, but the shoulder belt A2 directly extends to the waist belt A1 and is connected to the waist belt A1.

[0215] Reference Figure 1 , Figure 2 and Figure 5 , the side of the trunk support part A32 away from the hip support part A31, that is, the side of the child support part A3 away from the waist belt A1, is detachably connected to the shoulder belt A2, so that it is convenient for infants to enter and exit the accommodation space. When in use, the waist belt A1 can be fixed to the waist of the caregiver first, and the shoulder belt A2 can be hung on the shoulders of the caregiver. At this time, the connecting part A4 is close to the trunk of the caregiver, and then the infant can be picked up, and the side of the child support part A3 away from the waist belt A1 is connected to the shoulder belt A2, 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 part A4 and the child support part A3, which has a good wrapping and protection effect on the infant.

[0216] Furthermore, if Figure 1 and Figure 2As shown, the infant carrier also includes a leg support portion A51 (arranged on the left and right sides relative to the hip support portion A31). The leg support portion A51 is connected to the hip support portion A31 and can be switched between an expanded state and a folded state. The hip support portion A31 and the leg support portion A51 form a seat portion A6 for supporting infants. When the leg support portion A51 is in the expanded state, at least a portion of the leg support portion A51 (in this embodiment, the middle portion of the leg support portion A51) is substantially away from the hip support portion A31 in the lateral width direction of the child support A3 to increase the width of the seat portion A6. When the leg support portion A51 is in the folded state, at least a portion of the leg support portion A51 (in this embodiment, the middle portion of the leg support portion A51) is substantially close to the hip support portion A31 in the lateral width direction of the child support A3 to reduce the width of the seat portion A6.

[0217] It should be noted that the lateral width direction of the child support member A3 described in the previous paragraph and below specifically refers to the direction from the left side to the right side or from the right side to the left side of the child support member A3.

[0218] In this embodiment, if Figure 1 and Figure 2 As shown, the leg support part A51 is elastically connected to the buttocks support part A31 and can be switched between an expanded state and a folded state. Specifically, an elastic member A7 is connected between the buttocks support part A31 and the leg support part A51, and the elastic member A7 can be switched between an extended state and a non-extended state, so that the leg support part A51 can be switched between an expanded state and a folded state, thereby adjusting the width of the seat A6 in the lateral width direction, that is, adjusting the sitting width of the infant. Among them, the elasticity of the elastic member A7 is greater than the elasticity of the buttocks support part A31 and the leg support part A51, so that when the seat A6 is subjected to an external force, the elastic member A7, the buttocks support part A31 and the leg support part A51 are all stretched, and the elastic deformation of the elastic member A7 is greater than the elastic deformation of the buttocks support part A31 and the leg support part A51. It should be noted that the extended state of the elastic part A7 refers to the state in which the elastic part A7 is stretched under the action of an external force (for example, the action of the infant's own weight); the non-extended state of the elastic part A7 includes the natural extension state of the elastic part A7 when there is no external force or the force direction is inward squeezing, or the folded state in which the elastic part A7 is at least partially folded.

[0219] The infant carrier of this embodiment can automatically switch the leg support part A51 between the expanded state and the folded state under the weight of the infant, and can provide a suitable sitting width for the infant without manually adjusting the width of the seat part A6, which well meets the needs of infants of different body shapes and infants in different sitting directions for the sitting width, provides good support for the infant's buttocks and legs, and improves the comfort of the infant's sitting. The infant carrier of this embodiment has a simple structure and is easy to use. In this embodiment, the elastic member A7 can better wrap the infant's buttocks and legs, further increase the supporting effect of the seat part A6 on the infant, and improve the comfort of the infant's sitting.

[0220] Furthermore, the elastic member A7 can be switched between an extended state and a non-extended state according to the body shape of the infant or the sitting direction of the infant. Figure 1 When the infant sits forward, the sitting width required by the infant is small, the downward curvature of the seat A6 is small, and the tension F generated by the infant's gravity on the two sides of the elastic member A7 connected to the leg support A51 and the hip elastic member A7 is small (or because the elastic member A7 is still in a folded state, the two sides of the elastic member A7 have not yet been acted by the tension F), so that the elastic member A7 is generally in a non-extended state. Figure 2 When an infant sits with his back facing away, the width of the seat required by the infant is larger, and the downward curvature of the seat A6 is larger. The gravity of the infant generates a large pulling force F on both sides of the connection between the elastic member A7 and the leg support part A51 and the buttocks elastic member A7, so that the elastic member A7 is stretched to an extended state.

[0221] Similarly, when the infant is smaller in size, the sitting width required by the infant is smaller, and the pulling force F generated by the infant's gravity on the two sides where the elastic part A7 is connected to the leg support part A51 and the buttocks elastic part A7 is smaller (or because the elastic part A7 is still in a folded state, the two sides of the elastic part A7 have not yet been acted upon by the pulling force F), so that the elastic part A7 is roughly in a non-extended state; when the infant is larger in size, the pulling force F generated by the infant's gravity on the two sides where the elastic part A7 is connected to the leg support part A51 and the buttocks elastic part A7 is larger, so that the elastic part A7 is stretched to an extended state.

[0222] Furthermore, if Figure 1 and Figure 2 As shown, the two outer edges of the hip support part A31 in the transverse direction are arc-shaped edges that are recessed toward the middle of the child support part A3. This can facilitate the arrangement of the leg support part A51, and also enable the width of the seat part A6 to be reduced to a smaller size when the infant sits with his back to the caregiver or when the infant is small in size, so as not to cause the leg constriction phenomenon of the infant's legs.

[0223] like Figure 1 to Figure 2 As shown, both sides of the hip support part A31 in the transverse width direction are provided with a leg support part A51, that is, the two leg support parts A51 are respectively arranged on both sides of the outer edge A311 of the hip support part. The distance in the transverse width direction between the outer edges A513 of the two leg support parts forms the width of the seat part A6. Among them, the outer edge A513 of the leg support part refers to the side of the leg support part A51 away from the hip support part A31 in the transverse width direction of the child support part A3. When the leg support part A51 is in the unfolded state, the middle parts of the outer edges A513 of the two leg support parts are relatively far away from the hip support part A31, and when the leg support part A51 is in the folded state, the middle parts of the outer edges A513 of the two leg support parts are relatively close to the hip support part A31. The elastic part A7 is correspondingly arranged in two or two groups. Each leg support part A51 is connected to the hip support part A31 with an elastic part A7. For ease of description, the following description will be made by taking the leg supporting portion A51 and the elastic member A7 located on one side of the hip supporting portion A31 as an example.

[0224] Specifically, Figure 4 , Figure 6 and Figure 7 As shown, the leg support part A51 can be a multi-layer structure. A filling layer or filler is provided in the leg support part A51, so that the leg support part A51 can provide better support for infants and young children, and also make the infants and young children sit more comfortably. Among them, the filling layer or filler includes at least one of a hard sheet and an elastic filler. Similarly, the hip support part A31 can also be a multi-layer structure. A filling layer or filler is provided in the hip support part A31, so that the hip support part A31 can provide better support for infants and young children, and also make the infants and young children sit more comfortably.

[0225] The elastic member A7 connected between the leg support portion A51 and the hip support portion A31 can be a single-layer structure with a thickness less than that of the leg support portion A51 and the hip support portion A31, so as to improve the comfort of the infant. The elastic member A7 includes an elastic sheet made of a flexible elastic cloth, so that the elastic member A7 can be better switched between an extended state and a non-extended state. In other embodiments, the elastic member A7 includes at least one elastic belt made of a flexible elastic cloth or a combination of at least one elastic belt and at least one elastic sheet.

[0226] like Figures 3 to 6As shown, one end of the leg support portion A51 is used as the first connection end A511 and is connected to the child support member A3, and the other end of the leg support portion A51 is used as the second connection end A512 and is connected to the child support member A3 or the waist belt A1. Specifically, the first connection end A511 can be connected to the outer edge of one side of the hip support portion A31 close to the trunk support portion A32, and the second connection end A512 can be connected to the side of the waist belt A1 close to the hip support portion A31, that is, the first connection end A511 and the second connection end A512 are roughly distributed along the depth direction, and the first connection end A511 is located on the side of the second connection end A512 away from the waist belt A1. The portion of the leg support portion A51 between the first connection end A511 and the second connection end A512 is not directly connected to the hip support portion A31, so that at least part of the leg support portion A51 (the middle portion of the leg support portion A51 in this embodiment) can be moved away from or close to the seat portion A6 in the lateral width direction of the child support A3, thereby adjusting the width of the seat portion A6. In this embodiment, the first connection end A511 and the second connection end A512 of the leg support portion A51 are both fixedly or detachably connected to the child support A3 or the waist belt A1, so the first connection end A511 and the second connection end A512 of the leg support portion A51 are fixed relative to the child support A3. Therefore, the middle portion of the leg support portion A51 described in this paragraph and the foregoing specifically refers to the portion of the leg support portion A51 between the first connection end A511 and the second connection end A512. Of course, in other embodiments, the other end of the leg support portion A51 can also be connected to the hip support portion A31 at a position close to the waist belt A1. Or the other end of the leg support part A51 is connected to both the hip support part A31 and the waist belt A1. The present application does not limit the specific connection position of the leg support part A51, as long as the portion of the leg support part A51 between the first connection end A511 and the second connection end A512 can be relatively far away from or close to the seat part A6 in the lateral width direction of the child support part A3.

[0227] Reference Figures 3 to 6, the leg support part A51 has a linear first connection position A514, and the first connection position A514 deviates from the outer edge A513 of the leg support part A51. One side of the elastic member A7, such as an elastic sheet, in the transverse width direction of the child support part A3 is connected to the first connection position A514. Specifically, one side of the elastic member A7 in the transverse width direction is connected to the back side of the leg support part A51 (that is, the side of the leg support part A51 facing the infant). The elastic member A7 and the leg support part A51 can be connected by, for example, sewing. The hip support part A31 has a linear second connection position A312. The second connection position A312 is located at or near the outer edge of the hip support part A31 opposite to the first connection position A514. The second connection position A312 is spaced apart from the first connection position A514. The other side of the elastic member A7 (such as an elastic sheet) in the transverse width direction of the child support part A3 is connected to the second connection position A312. Specifically, the other side of the elastic member A7 in the lateral width direction of the child support member A3 can be connected to the back side of the hip support portion A31 (i.e., the side of the hip support portion A31 facing the infant), or can be connected to the inside of the hip support portion A31, i.e., connected to the multi-layer structure of the hip support portion A31. The elastic member A7 and the hip support portion A31 can be connected by, for example, sewing. In an embodiment where the elastic member A7 includes, for example, a plurality of elastic bands, one end of each elastic band can be connected to the back side of the leg support portion A51, and the other end can be connected to the inside of the hip support portion A31 or the back side of the hip support portion A31.

[0228] Reference Figure 4 , Figure 6 and Figure 7 , the portion of the leg support portion A51 close to the first connection end A511, the upper side of the elastic member A7, and the outer edge A311 of the hip support portion together enclose a first opening A81. This increases the elastic activity gap of the leg support portion A51. Correspondingly, the portion of the leg support portion A51 close to the second connection end A512, the lower side of the elastic member A7, and the outer edge A311 of the hip support portion together enclose a second opening A82. This increases the elastic activity gap of the leg support portion A51. Of course, in other embodiments, the first opening A81 and the second opening A82 may not be provided, or only the first opening A81 or the second opening A82 may be provided.

[0229] In one embodiment, if Figures 1 to 4As shown, the seat portion A6 also includes a wing portion A52, and the wing portion A52 is connected to the leg support portion A51 on one side in the lateral width direction of the child support member A3, and the wing portion A52 extends toward the hip support portion A31 on the other side in the lateral width direction of the child support member A3. Specifically, the wing portion A52 is connected to the first connection position A514 of the leg support portion A51 and at least partially covers the elastic member A7, the first opening A81 or the second opening A82, so that when the infant carrier is observed from the front (i.e., the side facing away from the infant), the infant carrier is more beautiful. In addition, by extending the wing portion A52 toward the hip support portion A31 in the lateral width direction, the support area at the first opening A81 and the second opening A82 is increased, so that the infant leg support is more comfortable. In this embodiment, the wing portion A52 is integrally formed with the leg support portion A51. In another embodiment, the wing portion A52 can be connected to the leg support portion A51 by, for example, sewing. Continue to refer to Figures 1 to 4 The wing portion A52 is correspondingly set to two, and the two wing portions A52 are respectively connected to the corresponding first connecting positions A514 in the two leg supporting portions A51.

[0230] In other embodiments not shown, the wing portion A52 may also be connected to the hip support portion A31 on one side of the child support member A3 in the lateral width direction and at least partially cover the elastic member A7, the first opening A81 and the second opening A82, so that the infant carrier is more beautiful when viewed from the front. In this embodiment, the wing portion A52 is integrally formed with the hip support portion A31. In other embodiments, the wing portion A52 may be connected to the hip support portion A31 by, for example, sewing.

[0231] The operating principle of the infant carrier in this embodiment is as follows:

[0232] Reference Figure 2 When the sitting width required for the infant's buttocks and legs is larger, for example, when the infant sits with his back to the caregiver (i.e., facing the caregiver), the downward curvature of the seat A6 is larger, and the pulling force F generated by the infant's gravity on both sides of the connection between the elastic member A7 and the leg support member A51 and the buttocks elastic member A7 is larger. The elastic member A7 is stretched to an extended state to better wrap the infant's legs and buttocks. At this time, the leg support member A51 is in an expanded state, and the middle parts of the two leg support members A51 are relatively far away from the buttocks support member A31. Correspondingly, the width of the seat A6 is increased, thereby ensuring that the baby's legs are in an M-shaped structure instead of hanging directly, which can provide good support for the infant's thighs. Figure 1When the sitting width required for the buttocks and legs of an infant is small, for example, when the infant sits with his back to the seat (i.e., facing the caregiver), the downward curvature of the seat portion A6 is small, and the pulling force F generated by the infant's gravity on both sides of the connection between the elastic member A7 and the leg support portion A51 and the buttocks elastic member A7 is small (or because the elastic member A7 is still in a folded state, the two sides of the elastic member A7 have not yet been affected by the pulling force F), and the elastic member A7 is in a non-extended state, so that the leg support portion A51 is in a retracted state, and the middle parts of the two leg support portions A51 are relatively close to the buttocks support portion A31, and correspondingly the width of the seat portion A6 is reduced, thereby not causing the leg to be strangled, making the infant sit more comfortably.

[0233] Of course, the width adjustment of the seat A6 is not limited to the situations where the infant sits with his back facing or facing forward. For example, under the same sitting mode, for infants of different sizes, larger infants have larger hips and legs, so the required width of the seat A6 is correspondingly larger. Larger infants have a larger weight, so when they sit, the elastic member A7 can be extended and partially wrap the infant's legs and buttocks, so that the leg support portion A51 is in an expanded state, thereby providing the infant with a larger seat A6 width, which can ensure that the baby's legs are in an M-shaped structure instead of hanging down directly, and can provide good support for the infant's thighs. Similarly, smaller infants and young children have smaller hip and leg sizes, so the required width of the seat portion A6 is correspondingly smaller. Smaller infants and young children have smaller weight, so when they sit, the elastic member A7 can be in a non-extended state, so that the leg support portion A51 is in a retracted state, and the middle portion of the leg support portion A51 is relatively close to the hip support portion A31, so that the width of the seat portion A6 is reduced, which will not cause the leg to be strangled, thereby making the infant and young child more comfortable to sit.

[0234] Figures 8 to 14 The second embodiment of the present application is shown in the figure. This embodiment is different from the previous embodiment in at least the following aspects:

[0235] In this embodiment, the seat A6 is not provided with the elastic member A7. The portion between the first connection end A511 and the second connection end A512 of the leg support A51 is spaced apart from the hip support A31 to form an adjustment port A83. The adjustment port A83 is in the open state (refer to Fig. 9 , Fig.13 and Fig.17 ) and closed state (refer to Figure 8 , Fig.10 and Fig.12 ) so that the leg support portion A51 can be switched between the expanded state and the folded state, so that the middle part of the leg support portion A51 can be moved away from or close to the seat portion A6, thereby adjusting the width of the seat portion A6.

[0236] In this embodiment, refer to Fig.10 and Fig.12 When the infant carrier is laid flat, adjust the opening A83 (refer to Fig.11 ) is blocked by the wing portion A52. Figure 8 When the infant sits forward, the sitting width required for the infant's buttocks and legs is small, the leg support part A51 is in a retracted state, and the middle part of the leg support part A51 is relatively close to the buttocks support part A31. At this time, the adjustment port A83 ( Figure 8 (not shown) is blocked by the leg support portion A51 or the wing portion A52. Fig. 9 and Fig.17 When the infant sits with his back facing the seat, the sitting width required for the infant's buttocks and legs is relatively large, the leg support part A51 is in an unfolded state, and the middle part of the leg support part A51 is relatively far away from the buttocks support part A31. At this time, the adjustment port A83 may be exposed (refer to Fig. 9 ) or may be blocked by the leg support portion A52 or the wing portion A52 (refer to Fig.14 ), and this application does not limit this. The arrangement of other components in this embodiment can refer to the above-mentioned embodiment, and will not be repeated here.

[0237] Figures 15 to 18 The third embodiment of the present application is shown in the figure. This embodiment is different from the first embodiment described above in at least the following aspects:

[0238] In this embodiment, if Fig.15 and Fig.16 As shown, the seat A6 is not provided with an elastic member A7. The leg support portion A51 is generally in a trapezoidal structure, including a first side A515 and a second side A516 that are relatively arranged and are generally parallel, and a third side A517 and a fourth side A518 that are relatively arranged and arranged at an angle. Among them, the first side A515 forms the outer edge A513 of the leg support portion, the length of the second side A516 is less than the length of the first side A515 and extends toward the middle of the horizontal width direction of the child support member A3, the third side A517 and the fourth side A518 are respectively connected between the first side A515 and the second side A516, and the third side A517 is relatively far away from the waist belt A1 relative to the fourth side A518.

[0239] like Fig.16As shown, the two ends of the first side A515 of the leg support part A51 are respectively the first connection end A511 and the second connection end A512. Similar to the first embodiment, the first connection end A511 is connected to the child support part A3, and the second connection end A512 is connected to the child support part A3 or the waist belt A1. The first connection end A511 is located on the side of the second connection end A512 away from the waist belt A1, and the position where the child support part A3 is connected to the first connection end A511 is the third connection position A313. The second side A516 of the leg support part A51 is connected to the fourth connection position A314 of the child support part A3. Specifically, the fourth connection position A314 is linear and is located on the back of the child support part A3 (that is, the side of the child support part A3 facing the infant). The fourth connection position A314 is specifically located on the hip support part A31 and is set away from the outer edge A311 of the hip support part. In this embodiment, the second side A516 of the leg support portion A51 is sewn and connected to the fourth connection position A314 of the child support member A3. Fig.17 The sewing lines of the second side A516 and the fourth connection position A314 cannot be seen from the front side of the child support A3 (i.e., the side of the child support A3 facing away from the infant), which can make the appearance of the child support A3 look more beautiful and neat when in use.

[0240] like Fig.16 As shown, the length of the leg support portion A51 from the first side A515 to the second side A516 is greater than the length from the third connection position A313 to the fourth connection position A314 of the child support A3, so that the leg support portion A51 can be switched between the unfolded state and the folded state. When the leg support portion A51 is in the unfolded state, the first side A515 of the leg support portion A51, that is, the outer edge A513 of the leg support portion is away from the hip support portion A31 in the lateral width direction of the child support A3 to increase the width of the seat portion A6. When the leg support portion A51 is in the folded state, the first side A515 of the leg support portion A51, that is, the outer edge A511 of the leg support portion is close to the hip support portion A31 in the lateral width direction of the child support A3 to reduce the width of the seat portion A6.

[0241] It should be understood that the length of the leg support portion A51 from the first side A515 to the second side A516 referred to herein specifically refers to the actual length of the fabric forming the leg support portion A51 between the first side A515 and the second side A516. Similarly, the length of the child support member A3 from the third connection position A313 to the fourth connection position A314 refers to the actual length of the fabric forming the child support member A3 between the third connection position A313 and the fourth connection position A314. In this embodiment, the leg support portion A51 includes a filling portion A5191 and a deformation portion A5192 adjacently arranged along the lateral width direction of the child support member A3. Specifically, the leg support portion A51 has a separation position A5193 between the first side A515 and the second side A516, the portion of the leg support portion A51 from the first side A515 to the separation position A5193 forms a filling portion A5191, and the portion of the leg support portion A51 from the separation position A5193 to the second side A516 forms a deformation portion A5192. Specifically, the filling portion A5191 is a multi-layer structure and a filling layer or filler is provided inside to provide sufficient support for the legs of infants and young children. The deformation portion A5192 is made of ordinary woven fabric. The separation position A5193 is a separation sewing line, and the filling portion A5191 and the deformation portion A5192 are separated by the separation sewing line.

[0242] The deformation part A5192 can be switched between a curled state and an extended state, so that the deformation part A5192 can be switched between an expanded state and a folded state. When the infant carrier is free of external force or the force direction is inwardly squeezed, when the deformation part A5192 is in a naturally curled state, the first side A515 of the leg support part A51, that is, the outer edge A513 of the leg support part, moves closer to the hip support part A31 in the lateral width direction of the child support part A3 to reduce the width of the seat part A6. When the infant carrier is subjected to external force, for example, when the infant is sitting on the infant carrier, the deformation part A5192 is appropriately stretched and in an extended state, and the first side A515 of the leg support part A51, that is, the outer edge A511 of the leg support part, moves away from the hip support part A31 in the lateral width direction of the child support part A3 to increase the width of the seat part A6.

[0243] Furthermore, if Fig.16 As shown, the length of the first side A515 of the leg support portion A51 is L1, and the length of the second side A516 of the leg support portion A51 is L2, then L1 and L2 satisfy the following relationship:

[0244] L2 / L1=1 / 3~1 / 2.

[0245] Such arrangement enables the second side A516 of the leg support portion A51 to have an appropriate length. Since the leg support portion A51 is used to connect to the fourth linear connection position A314 on the child support piece A3, the connection strength between the leg support portion A51 and the child support piece A3 and the supporting stability of the leg support portion A51 can be ensured.

[0246] Furthermore, if Fig.16 As shown, similar to the first embodiment, both sides of the hip support portion A31 in the transverse direction are provided with leg support portions A51. The distance between the second sides A516 of the two leg support portions A51 is W1, and the distance between the first sides A515 of the two leg support portions A51 is W2, then W1 and W2 satisfy the following relationship:

[0247] W1 / W2=1 / 3~2 / 3

[0248] Such arrangement enables the dimension of the leg support portion A51 in the lateral width direction and the dimension of the entire seat portion A6 in the lateral width direction to be maintained within a reasonable range, thereby ensuring the comfort and flexibility of the support of the seat portion A6 in the lateral width direction.

[0249] Furthermore, if Fig.17 and Fig.18 As shown, the third side A517 and the child support A3 are spaced apart to form a first opening A81, and the fourth side A518 and the child support A3 are spaced apart to form a second opening A82. The infant carrier also includes a wing portion A52, one side of the wing portion A52 is connected to the fifth connection position A615 of the hip support A31, and the side of the wing portion A52 away from the hip support A31 in the width direction forms a movable side A521, and the movable side A521 is spaced apart from the leg support A51 to form a third opening A84. The third opening A84 is connected to both the first opening A81 and the second opening A82, and the first opening A81 and the second opening A82 can be exposed through the third opening A84. The wing portion A52 at least partially covers the first opening A81 or the second opening A82 to keep the appearance of the child support A3 neat and beautiful, and the wing portion A52 can also play a certain supporting role. In this embodiment, the fifth connection position A315 and the fourth connection position A314 are actually located at the same position on the back and front sides of the child support member A3. Fig.17 and Fig.18As shown, when the infant carrier is naturally flat, the first opening A81 and the second opening A82 are blocked by the wing portion A52. When the infant is sitting forward, the sitting width required for the infant's buttocks and legs is small, and the leg support portion A51 is in a folded state, that is, the leg support portion A51 is curled because the length from the first side A515 to the second side A516 is greater than the length from the third connection position A313 to the fourth connection position A314 of the child support A3, so that the middle part of the leg support portion A51 is relatively close to the buttocks support portion A31. At this time, the first opening and the second opening A82 are blocked by the wing portion A52. When an infant sits with his back to the seat, the sitting width angle required for the infant's buttocks and legs is larger, and the leg support part A51 is in an expanded state, that is, the leg support part A51 is stretched out by the infant's buttocks and legs, so that the middle part of the leg support part A51 is relatively far away from the buttocks support part A31. At this time, the first opening A81 and the second opening A82 may be exposed through the third opening A84 or may be at least partially blocked by the wing part A52.

[0250] (II) Second Aspect of the Application

[0251] Embodiment 1

[0252] The first embodiment of the present disclosure provides a child carrier B1000. Figure 19 to Figure 20 As shown, the child carrier B1000 includes a waist belt B120, a shoulder strap B110, and a bearing assembly B200 respectively connected to the waist belt B120 and the shoulder strap B110. The shoulder strap B110 is arranged roughly along the depth direction of the bearing assembly B200. One side of the bearing assembly B200 is connected to the waist belt B120, and the side of the bearing assembly B200 away from the waist belt B120 is detachably connected to the shoulder strap B110. That is, the upper side of the bearing assembly B200 is connected to the shoulder strap B110, and the lower side of the bearing assembly B200 is connected to the waist belt B120. In this embodiment, the upper side of the bearing assembly B200 is detachably connected to the shoulder strap B110 via a connector (such as a buckle). In other embodiments, the bearing assembly B200 may also be fixedly connected to the shoulder strap B110. This application does not limit the specific connection method between the bearing assembly B200 and the shoulder strap B110. Refer to Figure 19 to Figure 20 The bearing assembly B200 includes a buttocks support portion B210 and a trunk support portion B220 connected to each other. In this embodiment, the bearing assembly B200 is formed in one piece. The side of the buttocks support portion B210 away from the trunk support portion B220 is connected to the waist belt B120, and the side of the trunk support portion B220 away from the buttocks support portion B210 is connected to the shoulder belt B110.

[0253] It is worth noting that the depth direction of the load-bearing component B200 described in the previous paragraph and the following text specifically refers to the direction from the side where the load-bearing component B200 is connected to the waist belt B120 to the side where the load-bearing component B200 is connected to the shoulder strap B110, that is, the direction from the lower side to the upper side or the upper side to the lower side of the load-bearing component B200.

[0254] Furthermore, if Fig.19 , Fig. 20 and 23 As shown, the child carrier B1000 also includes a connection portion B4 connected to the waist belt B120 and the shoulder strap B110. A storage space for accommodating infants is formed between the connection portion B4 and the load-bearing assembly B200. Wherein, the connection portion B4 includes a first connection portion B41 and a second connection portion B42, and the first connection portion B41 is a substantially rectangular piece of cloth. There are two first connection portions B41, and the two first connection portions B41 are arranged at intervals and connected to the corresponding shoulder straps B110. One side of the second connection portion B42 is respectively connected to the two second connection portions B42, and the other side of the second connection portion B42 is respectively connected to the two shoulder straps B110. In one embodiment, the connection portion B4 can also be an integrated piece of cloth, one side of the connection portion B4 is connected to the waist belt B120, and the other side of the connection portion B4 is connected to the shoulder straps B110. In another embodiment, the child carrier B1000 does not include the connecting portion B4, but the shoulder straps B110 extend to the waist belt B1 and are connected to the waist belt B120.

[0255] Reference Fig.19 , Fig. 20 and Fig.23 , the side of the trunk support part B220 away from the hip support part B210, that is, the side of the bearing assembly B200 away from the waist belt B120 is detachably connected to the shoulder belt B110, so as to facilitate the infant (also called child) to enter and exit the storage space. When in use, the waist belt B120 can be fixed to the waist of the caregiver first, and the shoulder belt B110 can be hung on the shoulders of the caregiver. At this time, the connecting part B4 is close to the trunk of the caregiver, and then the infant can be picked up, and the side of the bearing assembly B200 away from the waist belt B120 is connected to the shoulder belt B110, so that the infant can sit in the storage space. In the child carrier B1000 in this embodiment, the storage space is formed by the connecting part B4 and the bearing assembly B200, which has a good wrapping and protection effect on the infant.

[0256] Furthermore, if Fig.19 and Fig. 20As shown, the child carrier B1000 also includes a leg support portion B230 (arranged on the left and right sides relative to the hip support portion B210). The leg support portion B230 is connected to the hip support portion B210 and can be switched between an expanded state and a folded state. Specifically, the leg support portion B230 has a first connection end B231 and a second connection end B232, the first connection end B231 is connected to the bearing assembly B200, and the second connection end B232 is connected to the waist belt B120 or the bearing assembly B200. In the depth direction, at least a portion of the leg support portion B230 located between the first connection end B231 and the second connection end B232 is not connected to the hip support portion B210. The hip support portion B210 and the leg support portion B230 form a seat portion B6 for supporting infants and young children. When the leg support portion B230 is in the unfolded state, at least a portion of the leg support portion B230 (in this embodiment, the middle portion of the leg support portion B230) is approximately away from the hip support portion B210 in the lateral width direction of the load-bearing component B200, so that the seat portion B6 has a larger width. When the leg support portion B230 is in the folded state, at least a portion of the leg support portion B230 (in this embodiment, the middle portion of the leg support portion B230) is approximately close to the hip support portion B210 in the lateral width direction of the load-bearing component B200, so that the seat portion B6 has a smaller width.

[0257] It is worth noting that the lateral width direction of the carrier assembly B200 described in the previous paragraph and below specifically refers to the direction from the left side to the right side or from the right side to the left side of the carrier assembly B200.

[0258] In this embodiment, if Fig.19 and Fig. 20 As shown, the leg support part B230 is elastically connected to the buttocks support part B210 and can be switched between an expanded state and a folded state. Specifically, an elastic member B7 is connected between the buttocks support part B210 and the leg support part B230, and the elastic member B7 can be switched between an extended state and a non-extended state, so that the leg support part B230 can be switched between an expanded state and a folded state, thereby adjusting the width of the seat B6 in the horizontal width direction, that is, adjusting the sitting width of the infant. Among them, the elasticity of the elastic member B7 is greater than the elasticity of the buttocks support part B210 and the leg support part B230, so that when the seat B6 is subjected to an external force, the elastic member B7, the buttocks support part B210 and the leg support part B230 are all stretched, and the elastic deformation of the elastic member B7 is greater than the elastic deformation of the buttocks support part B210 and the leg support part B230. It should be noted that the extended state of the elastic part B7 refers to the state in which the elastic part B7 is stretched under the action of external force (for example, the action of the infant's own weight); the non-extended state of the elastic part B7 includes the natural extension state of the elastic part B7 when there is no external force or the force direction is inward squeezing, or the folded state in which the elastic part B7 is at least partially folded.

[0259] The child carrier B1000 of this embodiment can automatically switch the leg support part B230 between the expanded state and the folded state under the weight of the infant, without manually adjusting the width of the seat part B6, so as to provide a suitable sitting width for the infant, and well meet the needs of infants of different body shapes and infants in different sitting directions for the sitting width, provide good support for the infant's buttocks and legs, and improve the comfort of the infant's sitting. The child carrier B1000 of this embodiment has a simple structure and is easy to use. In this embodiment, the elastic member B7 can better wrap the infant's buttocks and legs, further increase the supporting effect of the seat part B6 on the infant, and improve the comfort of the infant's sitting.

[0260] Furthermore, the elastic member B7 can be switched between an extended state and a non-extended state according to the body shape of the infant or the sitting direction of the infant. Fig.19 When the infant sits forward, the required sitting width is small, the downward curvature of the seat B6 is small, and the tension F on both sides of the elastic member B7 connected to the leg support B230 and the hip elastic member B7 by the infant's gravity is small (or because the elastic member B7 is still in a folded state, the two sides of the elastic member B7 have not been acted by the tension F), so that the elastic member B7 is generally in a non-extended state. Fig. 20 When an infant sits with his back to the seat, the width of the seat required by the infant is larger, and the downward curvature of the seat B6 is larger. The gravity of the infant generates a large pulling force F on both sides of the connection between the elastic part B7 and the leg support part B230 and the hip elastic part B7, so that the elastic part B7 is stretched to an extended state.

[0261] Similarly, when the infant is smaller in size, the sitting width required by the infant is smaller, and the pulling force F generated by the infant's gravity on both sides of the connection between the elastic part B7 and the leg support part B230 and the hip elastic part B7 is smaller (or because the elastic part B7 is still in a folded state, the two sides of the elastic part B7 have not yet been affected by the pulling force F), so that the elastic part B7 is roughly in a non-extended state; when the infant is larger in size, the pulling force F generated by the infant's gravity on both sides of the connection between the elastic part B7 and the leg support part B230 and the hip elastic part B7 is larger, so that the elastic part B7 is stretched to an extended state.

[0262] Furthermore, if Fig.19 and Fig. 20 As shown, the two outer edges B214 of the hip support part B210 in the horizontal width direction are arc-shaped edges that are recessed toward the middle of the bearing assembly B200. This facilitates the arrangement of the leg support part B230, and also enables the width of the seat part B6 to be reduced to a smaller size when the infant sits with his back to the caregiver or when the infant is small in size, so as not to cause leg constriction on the infant's legs.

[0263] like Figure 19 to Figure 20 As shown, both sides of the hip support part B210 in the transverse width direction are provided with leg support parts B230, that is, the two leg support parts B230 are respectively arranged on both sides of the outer edge B214 of the hip support part. The distance in the transverse width direction between the outer edges B236 of the two leg support parts forms the width of the seat part B6. Among them, the outer edge B236 of the leg support part refers to the side of the leg support part B230 away from the hip support part B210 in the transverse width direction of the bearing assembly B200. When the leg support part B230 is in the unfolded state, the middle parts of the outer edges B236 of the two leg support parts are relatively far away from the hip support part B210, and when the leg support part B230 is in the folded state, the middle parts of the outer edges B236 of the two leg support parts are relatively close to the hip support part B210. The elastic member B7 is correspondingly arranged in two or two groups. Each leg support part B230 is connected to the hip support part B210 with an elastic member B7. For ease of description, the following description will be made by taking the leg supporting portion B230 and the elastic member B7 located on one side of the hip supporting portion B210 as an example.

[0264] Specifically, Fig. 22 , Fig.24 and Fig.25 As shown, the leg support part B230 can be a multi-layer structure. A filling layer or filler is provided in the leg support part B230, so that the leg support part B230 can provide better support for infants and young children, and also make the infants and young children sit more comfortably. Among them, the filling layer or filler includes at least one of a hard sheet and an elastic filler. Similarly, the hip support part B210 can also be a multi-layer structure. A filling layer or filler is provided in the hip support part B210, so that the hip support part B210 can provide better support for infants and young children, and also make the infants and young children sit more comfortably.

[0265] The elastic member B7 connected between the leg support portion B230 and the hip support portion B210 can be a single-layer structure with a thickness less than that of the leg support portion B230 and the hip support portion B210 to improve the comfort of the infant. The elastic member B7 includes an elastic sheet made of flexible elastic cloth, so that the elastic member B7 can be better switched between an extended state and a non-extended state. In other embodiments, the elastic member B7 includes at least one elastic belt made of flexible elastic cloth or a combination of at least one elastic belt and at least one elastic sheet.

[0266] like Figure 21 to Figure 24As shown, one end of the leg support part B230 serves as the first connection end B231 and is connected to the bearing assembly B200, and the other end of the leg support part B230 serves as the second connection end B232 and is connected to the bearing assembly B200 or the waist belt B120. Specifically, the first connection end B231 can be connected to the outer edge of one side of the hip support part B210 close to the trunk support part B220, and the second connection end B232 can be connected to the side of the waist belt B120 close to the hip support part B210, that is, the first connection end B231 and the second connection end B232 are roughly distributed along the depth direction, and the first connection end B231 is located on the side of the second connection end B232 away from the waist belt B120. The portion of the leg support portion B230 between the first connection end B231 and the second connection end B232 is not directly connected to the hip support portion B210, so that at least part of the leg support portion B230 (the middle portion of the leg support portion B230 in this embodiment) can move away from or close to the seat portion B6 in the lateral width direction of the support component B200, thereby adjusting the width of the seat portion B6. In this embodiment, the first connection end B231 and the second connection end B232 of the leg support portion B230 are both fixedly or detachably connected to the support component B200 or the waist belt B120, so the first connection end B231 and the second connection end B232 of the leg support portion B230 are fixed relative to the support component B200. It is worth noting that the middle portion of the leg support portion B230 specifically refers to the portion of the leg support portion B230 between the first connection end B231 and the second connection end B232. Of course, in other embodiments, the other end of the leg support part B230 may also be connected to the position of the hip support part B210 close to the waist belt B120. Or the other end of the leg support part B230 is connected to both the hip support part B210 and the waist belt B120. The present application does not limit the specific connection position of the leg support part B230, as long as the portion of the leg support part B230 located between the first connection end B231 and the second connection end B232 can be relatively far away from or close to the seat part B6 in the horizontal width direction of the bearing assembly B200.

[0267] Reference Figure 21 to Figure 24, the leg support part B230 has a linear first connection position B237, and the first connection position B237 deviates from the outer edge B236 of the leg support part. One side of the elastic member B7, such as an elastic sheet, in the transverse width direction of the bearing assembly B200 is connected to the first connection position B237. Specifically, one side of the elastic member B7 in the transverse width direction is connected to the back side of the leg support part B230 (that is, the side of the leg support part B230 facing the infant). The elastic member B7 and the leg support part B230 can be connected by, for example, sewing. The hip support part B210 has a linear second connection position B215. The second connection position B215 is located at or near the outer edge of the hip support part B210 opposite to the first connection position B237. The second connection position B215 is spaced apart from the first connection position B237. The other side of the elastic member B7 (such as an elastic sheet) in the transverse width direction of the bearing assembly B200 is connected to the second connection position B215. Specifically, the other side of the elastic member B7 in the lateral width direction of the bearing assembly B200 can be connected to the back side of the hip support portion B210 (i.e., the side of the hip support portion B210 facing the infant), or can be connected to the inside of the hip support portion B210, i.e., connected to the multi-layer structure of the hip support portion B210. The elastic member B7 and the hip support portion B210 can be connected by, for example, sewing. In an embodiment in which the elastic member B7 includes, for example, a plurality of elastic bands, one end of each elastic band can be connected to the back side of the leg support portion B230, and the other end can be connected to the inside of the hip support portion B210 or the back side of the hip support portion B210.

[0268] Reference Fig. 22 , Fig.24 and Fig.25 , the portion of the leg support portion B230 close to the first connection end B231, the upper side of the elastic member B7, and the outer edge B214 of the hip support portion together enclose a first opening B233. This increases the elastic activity gap of the leg support portion B230. Correspondingly, the portion of the leg support portion B230 close to the second connection end B232, the lower side of the elastic member B7, and the outer edge B214 of the hip support portion together enclose a second opening B234. This increases the elastic activity gap of the leg support portion B230. Of course, in other embodiments, the first opening B233 and the second opening B234 may not be provided, or only the first opening B233 or the second opening B234 may be provided.

[0269] In one embodiment, if Figures 19 to 22As shown, the seat B6 also includes a wing portion B52, and the wing portion B52 is connected to the leg support portion B230 on one side in the horizontal width direction of the bearing assembly B200, and the wing portion B52 extends to the hip support portion B210 on the other side in the horizontal width direction of the bearing assembly B200. Specifically, the wing portion B52 is connected to the first connection position B237 of the leg support portion B230 and at least partially covers the elastic member B7, the first opening B233 and the second opening B234, so that when the child carrier B1000 is observed from the front side (i.e., the side facing away from the infant), the child carrier B1000 is more beautiful. In addition, the wing portion B52 extends toward the hip support portion B210 in the horizontal width direction, increasing the support area at the first opening B233 and the second opening B234, so that the infant's leg support is more comfortable. In this embodiment, the wing portion B52 is integrally formed with the leg support portion B230. In another embodiment, the wing portion B52 can be connected to the leg support portion B230 by, for example, sewing. Figures 19 to 22 The wing portion B52 is correspondingly set to two, and the two wing portions B52 are respectively connected to the corresponding first connecting positions B237 in the two leg supporting portions B230.

[0270] In other embodiments not shown, the wing portion B52 may also be connected to the hip support portion B210 on one side of the load-bearing assembly B200 in the lateral width direction and at least partially cover the elastic member B7, the first opening B233 and the second opening B234, so that the child carrier B1000 is more beautiful when viewed from the front. In this embodiment, the wing portion B52 is integrally formed with the hip support portion B210. In other embodiments, the wing portion B52 may be connected to the hip support portion B210 by, for example, sewing.

[0271] The operating principle of the child carrier B1000 in this embodiment is as follows:

[0272] Reference Fig. 20 When the sitting width required for the infant's buttocks and legs is larger, for example, when the infant sits with his back to the caregiver (i.e. facing the caregiver), the downward curvature of the seat B6 is larger, and the pulling force F generated by the infant's gravity on both sides of the connection between the elastic member B7 and the leg support member B230 and the buttocks elastic member B7 is larger. The elastic member B7 is stretched to an extended state to better wrap the infant's legs and buttocks. At this time, the leg support member B230 is in an expanded state, and the middle parts of the two leg support members B230 are relatively far away from the buttocks support member B210. Correspondingly, the width of the seat B6 is increased, thereby ensuring that the baby's legs are in an M-shaped structure instead of hanging directly, which can provide good support for the infant's thighs. Fig.19When the sitting width required for the buttocks and legs of an infant is small, for example, when the infant sits with his back to the seat (i.e., facing the caregiver), the downward curvature of the seat portion B6 is small, and the pulling force F generated by the infant's gravity on the two sides of the connection between the elastic member B7 and the leg support portion B230 and the buttocks elastic member B7 is small (or because the elastic member B7 is still in a folded state, the two sides of the elastic member B7 have not yet been subjected to the pulling force F), and the elastic member B7 is in a non-extended state, so that the leg support portion B230 is in a retracted state, and the middle parts of the two leg support portions B230 are relatively close to the buttocks support portion B210, so that the seat portion B6 has a smaller width, thereby not causing the leg to be strangled, making the infant sit more comfortably.

[0273] Of course, the width adjustment of the seat B6 is not limited to the situations where the infant sits with his back facing or facing forward. For example, under the same sitting mode, for infants of different sizes, larger infants have larger hips and legs, so the required width of the seat B6 is correspondingly larger. Larger infants have a larger weight, so when they sit, the elastic part B7 can be extended and partially wrap the infant's legs and buttocks, so that the leg support part B230 is in an expanded state, thereby providing the infant with a larger seat B6 width, which can ensure that the baby's legs are in an M-shaped structure instead of hanging down directly, and can provide good support for the infant's thighs. Similarly, smaller infants and young children have smaller hip and leg sizes, so the required width of the seat portion B6 is also correspondingly smaller. Smaller infants and young children have smaller weight, so when they sit, the elastic member B7 can be in a non-extended state, so that the leg support portion B230 is in a retracted state, and the middle part of the leg support portion B230 is relatively close to the hip support portion B210, so that the seat portion B6 has a smaller width, which will not cause the infant's legs to be strangled, thereby making the infant more comfortable to sit.

[0274] Embodiment 2

[0275] Figure 26 to Figure 32 A child carrier B1000 according to a second embodiment of the present disclosure is shown. This embodiment differs from the first embodiment described above in at least the following ways:

[0276] In this embodiment, the seat B6 is not provided with the elastic member B7. The portion between the first connection end B231 and the second connection end B232 of the leg support B230 is spaced apart from the hip support B210 to form an adjustment port B235. The adjustment port B235 is in the open state (refer to Fig. 27 , Fig.31 and Fig.32 ) and closed state (refer to Fig.26 , Fig.28 and Fig.30) so that the leg support part B230 can be switched between the expanded state and the folded state, so that the middle part of the leg support part B230 can be away from or close to the seat part B6, thereby adjusting the width of the seat part B6.

[0277] In this embodiment, refer to Fig.28 and Fig.30 When the child carrier B1000 is laid flat, the adjustment opening B235 (refer to Fig.29 ) is blocked by the wing portion B52. Fig.26 When the infant sits forward, the sitting width required for the infant's buttocks and legs is small, the leg support part B230 is in a retracted state, and the middle part of the leg support part B230 is relatively close to the buttocks support part B210. At this time, the adjustment port B235 ( Fig.26 (not shown) is blocked by the leg support portion B230 or the wing portion B52. Fig. 27 and Fig.35 When the infant sits with his back facing the seat, the sitting width required for the infant's buttocks and legs is relatively large, the leg support part B230 is in an unfolded state, and the middle part of the leg support part B230 is relatively far away from the buttocks support part B210. At this time, the adjustment port B235 may be exposed (refer to Fig. 27 ) or may be blocked by the leg support portion B230 or the wing portion B52 (refer to Fig.32 ), and this application does not limit this. The arrangement of other components in this embodiment can refer to the above-mentioned embodiment, and will not be repeated here.

[0278] Embodiment 3

[0279] The third embodiment of the present disclosure provides a child carrier B1000, such as Fig.33As shown, the child carrier B1000 includes a waist belt B120, a shoulder belt B110, a bearing assembly B200 connected to the waist belt B120 and the shoulder belt B110 respectively, and a leg support portion B230 connected to the bearing assembly B200. The shoulder belt B110 is arranged roughly along the depth direction of the bearing assembly B200. One side of the bearing assembly B200 is connected to the waist belt B120, and the side of the bearing assembly B200 away from the waist belt B120 is detachably connected to the shoulder belt B110. That is, the upper side of the bearing assembly B200 is connected to the shoulder belt B110, and the lower side of the bearing assembly B200 is connected to the waist belt B120. The part of the bearing assembly B200 close to the waist belt B120 forms a buttocks support portion B210, and the upper side of the bearing assembly B200 forms a trunk support portion B220. The leg support portion B230 is connected to the hip support portion B210 and together with the leg support portion B230 forms a seat portion B6 for supporting an infant. The leg support portion B230 can be switched between an expanded state and a folded state. When the leg support portion B230 is in an expanded state, the leg support portion B230 is away from the hip support portion B210 in the lateral width direction of the bearing assembly B200, so that the seat portion B6 has a larger width. When the leg support portion B230 is in a folded state, the leg support portion B230 moves closer to the hip support portion B210 in the lateral width direction of the bearing assembly B200, so that the seat portion B6 has a smaller width. It should be understood that the larger width and the smaller width in this article can be referred to as the first width and the second width, respectively, and the second width is smaller than the first width.

[0280] There are at least the following differences between this embodiment and the child carrier B1000 in the aforementioned embodiment.

[0281] like Fig.33 and Fig.34 As shown, the first connection end B231 of the leg support part B230 is connected to the load-bearing component B200, and the second connection end B232 of the leg support part B230 is connected to the load-bearing component B200 or the waist belt B120. In the depth direction, at least a portion of the leg support part B230 located between the first connection end B231 and the second connection end B232 is not connected to the hip support part B210. In this embodiment, the number of leg support parts B230 is two, but not limited to this. The two leg support parts B230 are respectively located on the left and right sides of the hip support part B210. Fig.33 and Fig.34 The leg supporting part B230 includes a first leg supporting part B230e located on the left side of the hip supporting part B210 and a second leg supporting part B230f located on the right side of the hip supporting part B210. Fig.34In the present embodiment, the portion of the leg support portion B230 between the first connection end B231 and the second connection end B232 is not directly connected to the hip support portion B210, so that at least a portion of the leg support portion B230 (the middle portion of the leg support portion B230 in the present embodiment) is spaced apart from the hip support portion B210 and forms an adjustment opening B235. Specifically, in the present embodiment, the leg support portion B230 is connected to the hip support portion B210 via an elastic member B7 between the approximately middle portion in the depth direction of the leg support portion B230, and the elastic member B7 at least partially covers the adjustment opening B235. The elastic member B7 is switchable between an extended state and a non-extended state, so that the leg support portion B230 can be expanded or retracted relative to the hip support portion B210 (that is, equivalent to enabling the edge line 236 of the leg support portion B230 to be away from or close to the hip support portion B210). More specifically, referring to Fig.33 , the elastic member B7 partially covers the adjustment opening B235, and the portion of the adjustment opening B235 not covered by the elastic member B7 forms a first opening B233 located on the upper side of the elastic member B7 and a second opening B234 located on the lower side of the elastic member B7. The elastic member B7, the leg support portion B230 and the hip support portion B210 together form the seat portion B6. In this embodiment, the number of elastic members B7 corresponds to the number of leg support portions B230, that is, the approximately longitudinal middle portion of each leg support portion B230 is connected to the hip support portion B210 through an elastic member B7. In other embodiments, for each leg support B230, two or more elastic members B7 may be provided in the depth portion of each leg support B230 between the first connection end B231 and the second connection end B232, and the two or more elastic members B7 are provided at intervals in the depth direction, and the leg support B230 is connected to the hip support through these elastic members B7, so that at least a portion of the leg support B230 between the first connection end B231 and the second connection end B232 is not connected to the hip support B210. In an alternative embodiment, the elastic member B7 may not be provided between the leg support B230 and the hip support B210, and the leg support B230 may be switched between the open state and the closed state through the adjustment port B235, so that the leg support B230 can be expanded or retracted relative to the hip support B210.

[0282] like Fig.33As shown, the child carrier B1000 is also provided with an adjustment mechanism B800, and the adjustment mechanism B800 is configured to expand or fold the hip support part B210. Among them, when the leg support part B230 is in the expanded state, the leg support part B230 is away from the hip support part B210 in the horizontal width direction of the bearing assembly B200, which is equivalent to the outer edge B236 of the leg support part B230 being away from the hip support part B210 in the horizontal width direction. In this way, the width of the seat B6 can be increased, that is, the seat B6 has a larger width. When the leg support part B230 is in the folded state, the leg support part B230 is close to the hip support part B210 in the horizontal width direction of the bearing assembly B200, which is equivalent to the outer edge B236 of the leg support part B230 being close to the hip support part B210 in the horizontal width direction. In this way, the seat B6 can have a smaller width. Among them, the adjustment mechanism B800 has an open state and a locked state. When the adjustment mechanism B800 is in the open state, the leg support part B230 can be expanded relative to the hip support part B210, so that the seat part B6 has a larger width; when the adjustment mechanism B800 is in the locked state, the leg support part B230 is retracted relative to the hip support part B210, so that the seat part B6 has a smaller width.

[0283] like Figure 34 to Figure 35As shown, the adjustment mechanism B800 includes a first adjustment member B810 and a second adjustment member B820. The first adjustment member B810 is connected to the first leg support portion B230e, and the second adjustment member B820 is connected to the second leg support portion B230b. Among them, the first adjustment member B810 includes a first adjustment belt B811 and a first matching portion B812 arranged on the first adjustment belt B811, and the first adjustment belt B811 is connected between the first leg support portion B230e and the first matching portion B812. That is, it is equivalent to the first matching portion B812 being connected to the first leg support portion B230e through the first adjustment belt B811. The second adjustment member B820 includes a second adjustment belt B821 and a second matching portion B822 arranged on the second adjustment belt B821, and the second adjustment belt B821 is connected to the second leg support portion B230f. That is, it is equivalent to the second matching portion B822 being connected to the second leg support portion B230f through the second adjustment belt B821. The second matching portion B822 is suitable for matching with the first matching portion B812 to detachably connect the first adjustment belt B811 and the second adjustment belt B821 together, so that the adjustment mechanism B800 can be switched between an open state and a locked state. When the first matching portion B812 and the second matching portion B822 match each other (that is, the adjustment mechanism B800 is in a locked state), the two leg support portions B230 are relatively close to each other, thereby reducing the width of the seat portion B6 (that is, even if the seat portion B6 has a relatively small width). When the first matching portion B812 and the second matching portion B822 are separated from each other (that is, the adjustment mechanism B800 is in an open state), the two leg support portions B230 are relatively far away from each other, thereby increasing the width of the seat portion B6 (that is, even if the seat portion B6 has a relatively large width).

[0284] It should be noted that, in this embodiment, when the adjustment mechanism B800 is in the open state, the relative position adjustment between the leg support part B230 and the hip support part B210 (i.e., the width adjustment of the seat part B6) is the same as the aforementioned first embodiment or the second embodiment, and will not be repeated here.

[0285] like Fig.34 and Fig.35As shown, one end of the first adjustment belt B811 is connected to the first leg support portion B230e and formed as a first fixed end B8111. The first matching portion B812 is arranged on the first adjustment belt B811. One end of the second adjustment belt B821 is connected to the second leg support portion B230f and formed as a second fixed end B8211, and the second matching portion B822 is arranged on the second adjustment belt B821. Furthermore, the first matching portion B812 is movably arranged on the first adjustment belt B811 to allow adjustment of the length of the first adjustment belt B811 between the first fixed end B8111 and the first matching portion B812 (i.e., the first adjustment length), thereby adjusting the width of the seat portion B6 when the adjustment mechanism B800 is in a locked state. The second matching portion B822 can be movably disposed on the second adjustment band B821 to allow adjustment of the length of the second adjustment band B821 between the second fixed end B8211 and the second matching portion B822 (ie, the second adjustment length), thereby adjusting the width of the seat B6 when the adjustment mechanism B800 is in a locked state.

[0286] Of course, in some alternative embodiments, it can be that: the first matching part B812 is fixedly set on the first adjustment band B811, the second matching part B822 is fixedly set on the second adjustment band B821, and the first adjustment length and the second adjustment length are both fixed; or: the first matching part B812 is movably set on the first adjustment band B811, the second matching part B822 is fixedly set on the second adjustment band B821, the first adjustment length can be adjusted and changed, and the second adjustment length is fixed; or: the second matching part B822 is movably set on the second adjustment band B821, the first matching part B812 is fixedly set on the first adjustment band B811, the second adjustment length can be adjusted and changed, and the first adjustment length is fixed.

[0287] Reference Fig.34 In this embodiment, the first matching part is a male buckle, and the second matching part is a female buckle suitable for buckling with the male buckle. In some alternative embodiments, the first matching part is, for example, a hook, and the second matching part is, for example, a hanging ring. Alternatively, the first matching part and the second matching part are a pair of snaps that can buckle with each other. Alternatively, the first matching part and the second matching part are Velcro that match each other.

[0288] Back to Fig.34 and Fig.35As shown, the first adjustment belt B811 and the second adjustment belt B821 are respectively connected to the middle part of the corresponding leg support part B230, specifically, the first fixed end B8111 and the second fixed end B8211 are respectively connected to the middle part of the corresponding leg support part B230 in the depth direction. The leg support part B230 includes a first side B238 close to the hip support part B210 and a second side B239 away from the hip support part B210. Among them, the first fixed end B8111 is connected to the second side B239 of the first leg support part B230e, or connected to its first side B238, or connected between its second side B239 and its first side B238; the second fixed end B8211 is connected to the second side B239 of the second leg support part B230f, or connected to its first side B238, or connected between its second side B239 and its first side B238. In this embodiment, the second side B239 of the leg support part B230 forms the outer edge B236 of the leg support part B230. The first fixed end B8111 and the second fixed end B8211 are respectively connected to the first side B238 of the corresponding leg support part B230. The first adjustment belt B811 is connected to the front of the leg support part B230 (i.e., the side of the leg support part B230 facing away from the infant when in use) or connected to the inside of the leg support part B230 (i.e., when the leg support part B230 is a multi-layer structure, it is connected between the multi-layer structures), and the first adjustment belt B811 is at least partially located on the front of the hip support part B210 (i.e., the side of the hip support part B210 facing away from the infant when in use). The second adjustment belt B821 is connected to the front of the leg support part B230 or connected to the inside of the leg support part B230 through the second fixed end B8211. The second adjustment belt B821 is at least partially located on the front of the hip support portion B210, so that the first adjustment member B810 and the second adjustment member B820 can be operated conveniently, and the first adjustment member B810 and the second adjustment member B820 can be prevented from interfering with the infant riding on the child carrier B1000.

[0289] like Fig.34As shown, the bearing assembly B200 is also provided with a first limiting ring B911 and a second limiting ring B912, and the first adjustment belt B811 is inserted in the first limiting ring B911 to limit and guide the first adjustment belt B811. The second adjustment belt B821 is inserted in the second limiting ring B912 to limit and guide the second adjustment belt B821, and can limit the extension direction of the second adjustment belt B821. Furthermore, the size of the first matching portion B812 in the depth direction is greater than the size of the first limiting ring B911 in this direction, so that the movement of the first matching portion B812 toward the first fixed end B8111 is limited by the first limiting ring B911; similarly, the size of the second matching portion B822 in the depth direction is greater than the size of the second limiting ring B921 in this direction, and the movement of the second matching portion B822 toward the second fixed end B8211 is also limited by the second limiting ring B912. Among them, the first limiting ring B911 and the second limiting ring B912 have the same structure, and the number of the first limiting ring B911 can be one or more; the number of the second limiting ring B912 can be one or more, and this application does not limit this. The first limiting ring B911 and the second limiting ring B912 are, for example, cloth rings sewn on the front of the hip support part B210, but are not limited to this. The first limiting ring B911 and the second limiting ring B912 are spaced apart in the horizontal width direction. The first fixed end B8111, the first limiting ring B911, the second limiting ring B912 and the second fixed end B8211 are roughly located on the same straight line (or the same arc) along the horizontal width direction.

[0290] like Fig.33As shown, optionally, a shielding member B920 is also provided on the bearing assembly B200, and the shielding member B920 is connected to the front of the bearing assembly B200 to cover the first adjustment member B810 and the second adjustment member B820, so that the front of the child carrier B1000 is neater and more beautiful. At least a part of the shielding member B920 is not connected to the bearing assembly B200, so that an operating port B921 is formed between the shielding member B920 and the bearing assembly B200, thereby allowing the first adjustment member B810 and the second adjustment member B820 to be operated through the operating port B921. Specifically, the shielding member B920 is, for example, a shielding cloth piece. The shielding member B920 has an upper end 922 and a lower end 923 that are opposite in the depth direction, and the upper end 922 and the lower end 923 of the shielding member B920 are respectively fixed to the bearing assembly B200 by, for example, sewing. At least a portion of both sides of the shielding member B920 in the horizontal width direction is not connected to the bearing assembly B200, so that two operation ports B921 that are interconnected in the horizontal width direction are formed between the shielding member B920 and the bearing assembly B200. More specifically, the first adjustment member B810 and the second adjustment member B820 extend between the shielding member B920 and the bearing assembly B200 through the corresponding operation ports B921, and the sizes of the two operation channels are suitable for the user to extend his hand to operate the first adjustment member B810 and the second adjustment member B820. In this embodiment, the shielding member B920 and the bearing assembly B200 form a pocket 925 to accommodate the first adjustment member B810 and the second adjustment member B820. Among them, the operation port B921 forms the opening of the pocket 925, and the first adjustment member B810 and the second adjustment member B820 accommodated in the pocket 925 can be operated through the operation port B921. In an alternative embodiment, the shielding member B920 is a multi-layer woven fabric structure, a pocket 925 is formed inside the shielding member B920 (ie, between the multi-layer woven fabric), and an opening of the pocket 925 is provided between the multi-layer woven fabric.

[0291] The operating principle of the child carrier B1000 in this embodiment is as follows.

[0292] When the width of the seat B6 required by the infant is relatively small (for example, the infant is sitting in the child carrier B1000 in the forward direction, or the infant is relatively small), the adjustment mechanism B800 is kept in a locked state (that is, the first matching portion B812 and the second matching portion B822 are matched with each other), and the outer edges B236 of the two leg support portions B230 are both close to the hip support portion B210, so that the outer edges B236 of the two leg support portions B230 are close to each other, thereby reducing the width of the seat B6 (that is, making the seat B6 have a relatively small width). In this embodiment, the setting of the adjustment mechanism B800 can limit the width of the seat B6 to a relatively small range, so as to better meet the infant's requirements for the width of the seat B6 and avoid repeated adjustment of the leg support portion B230, so that the child carrier B1000 can be used more conveniently. At the same time, when the adjustment mechanism B800 is in the locked state, it also provides a certain support for the seat B6 area, thereby reducing the probability of deformation and failure of the seat B6 and the elastic member B7.

[0293] When the width of the seat B6 required by the infant is larger (for example, the infant is sitting on the child carrier B1000 with his back facing away, or the infant is larger in size), the following different adjustment methods can be used.

[0294] Method 1: Switch the adjustment mechanism B800 to the open state (that is, separate the first matching part B821 and the second matching part B822), the width of the seat B6 can be adjusted by the method in the aforementioned embodiment 1 or embodiment 2, which will not be repeated here.

[0295] Method 2: Keep the adjustment mechanism B800 in a locked state (that is, the first mating part B812 is engaged with the second mating part B822), and change the first adjustment length (and / or the second adjustment length) by adjusting the position of the first mating part B812 on the first adjustment band B811 (and / or the position of the second mating part B822 on the second adjustment band B821), so that the seat B6 has a larger width.

[0296] Embodiment 4

[0297] The fourth embodiment of the present disclosure provides a child carrier B1000, such as Fig.36As shown, the child carrier B1000 includes a waist belt B120, a shoulder belt B110, a bearing assembly B200 connected to the waist belt B120 and the shoulder belt B110 respectively, and a leg support portion B230 connected to the bearing assembly B200. The shoulder belt B110 is arranged roughly along the depth direction of the bearing assembly B200. One side of the bearing assembly B200 is connected to the waist belt B120, and the side of the bearing assembly B200 away from the waist belt B120 is detachably connected to the shoulder belt B110. That is, the upper side of the bearing assembly B200 is connected to the shoulder belt B110, and the lower side of the bearing assembly B200 is connected to the waist belt B120. The part of the bearing assembly B200 close to the waist belt B120 forms a buttocks support portion B210, and the upper side of the bearing assembly B200 forms a trunk support portion B220. The leg support portion B230 is connected to the hip support portion B210 and together with the leg support portion B230 forms a seat portion B6 for supporting infants and young children. The leg support portion B230 can be switched between an expanded state and a folded state. When the leg support portion B230 is in an expanded state, the leg support portion B230 is away from the hip support portion B210 in the lateral width direction of the bearing assembly B200, so that the seat portion B6 has a larger width. When the leg support portion B230 is in a folded state, the leg support portion B230 moves closer to the hip support portion B210 in the lateral width direction of the bearing assembly B200, so that the seat portion B6 has a smaller width.

[0298] There are at least the following differences between this embodiment and the child carrier B1000 in the aforementioned third embodiment.

[0299] Reference Fig.37, the second connection end B232 of the leg support part B230 is connected to the bearing assembly B200 or the waist belt B120. At least a part of the first connection end B231 is formed as a movable end B231a, which is not connected to the bearing assembly B200, that is, it is equivalent to the movable end B231a not being connected, so that the first connection end B231 can move relative to the leg support part B230. In the depth direction, the part of the leg support part B230 located between the first connection end B231 and the second connection end B232 is not directly connected to the hip support part B210, so that at least part of the leg support part B230 (in this embodiment, the middle part of the leg support part B230) is spaced apart from the hip support part B210 and forms an adjustment port B235. Specifically, the leg support part B230 and the hip support part B210 are connected by an elastic member B7, and the elastic member B7 at least partially covers the adjustment port B235. The elastic member B7 can be switched between an extended state and a non-extended state, so that the leg support portion B230 can be expanded or retracted relative to the hip support portion B210. That is, in this embodiment, the middle portion of the leg support portion B230 is connected to the hip support portion B210 through the elastic member B7. In an alternative embodiment, the elastic member B7 may not be provided between the leg support portion B230 and the hip support portion B210, and a portion of the middle portion of the leg support portion B230 is directly connected to the hip support portion B210.

[0300] like Fig.36 and Fig.37 As shown, the child carrier B1000 is also provided with an adjustment mechanism B800, and the first connection end B231 of one of the two leg support parts B230 is suitable for connecting with the first connection end B231 of the other of the two leg support parts B230 through the adjustment mechanism B800. The adjustment mechanism B800 has an open state and a locked state. When the adjustment mechanism B800 is in the open state, the width of the seat B6 is relatively large. When the adjustment mechanism B800 is in the locked state, the first connection ends B231 of the two leg support parts B230 are connected to each other through the adjustment mechanism B800, and the width of the seat B6 is relatively small at this time, which is smaller than the width of the seat B6 when the adjustment mechanism B800 is in the open state.

[0301] The adjustment mechanism B800 includes a first adjustment member B810 and a second adjustment member B820. The first adjustment member B810 includes a first adjustment belt B811 and a first matching portion B812 arranged on the first adjustment belt B811. One end of the first adjustment belt B811 is connected to the movable end B231a of the first leg support portion B230e, and the other end extends in the direction of the second leg support portion B230f. The second adjustment member B820 includes a second adjustment belt B821 and a second matching portion B822 arranged on the second adjustment belt B821. One end of the second adjustment belt B821 is connected to the movable end B231a of the second leg support portion B230f, and the other end extends in the direction of the leg support portion B230 connected to the first adjustment belt B811. Among them, the first adjustment belt B811 and the first leg support portion B230e form an integral component, and the second adjustment belt B821 and the second leg support portion B230f form an integral component. The first matching portion B811 is suitable for matching with the second matching portion B821 to connect the first adjustment belt B811 and the second adjustment belt B821 together. It is worth noting that in the present embodiment, the mobility of the two movable ends B231a of the leg support portion can be limited in a suitable manner, so that when the two adjustment members B810 and B820 are not connected, the movable end B231a of the leg support portion can provide appropriate support, and the width of the seat portion B6 is relatively large. For example, a limiting structure is provided at a position corresponding to the movable end B231a of the hip support portion B210 or the shielding piece B920, and the limiting structure can be used to limit the mobility of the movable end B231a; or, there is a large friction force between the movable end B231a and the hip support portion B210 and / or the shielding piece B920 under normal conditions, so that the large friction force can be used to limit the mobility of the movable end B231a. In other embodiments, the movable end B231a of the leg support portion is highly movable, so that when the two adjustment members B810 and B820 are not connected, the movable end B231a of the leg support portion cannot provide support and the width of the seat portion B6 is relatively small.

[0302] Optionally, the number of at least one of the second matching part B822 and the first matching part B812 is at least two, so that the first adjustment band B811 and the second adjustment band B821 can be connected to each other at different positions through the mutual cooperation between the second matching part B822 and the first matching part B812, that is, the adjustment mechanism B800 has different width adjustment gears of the seat B6.

[0303] Reference Figure 36 to Figure 37, the number of the first matching parts B812 is, for example, one, and the number of the second matching parts B822 is, for example, at least two. The at least two second matching parts B822 include a second matching part B822a and a second matching part B822b, and the second matching part B822a is closer to the first adjustment belt B811 in the horizontal width direction than the second matching part B822b. When the first matching part B812 is matched with the second matching part B822a, the adjustment mechanism B800 is in the first locking state, the leg support part B230 is in the first folded state, and the seat part B6 has a relatively large folded width, which is smaller than the width when the adjustment mechanism B800 is in the open state. When the first matching part B812 is matched with the second matching part B822b, the adjustment mechanism B800 is in the second locking state, the leg support part B230 is in the second folded state, and the seat part B6 has a relatively small folded width, which is smaller than the above-mentioned relatively large folded width.

[0304] In some alternative embodiments, the number of the first matching parts B812 is at least two, and the number of the second matching parts B822 is one, so that the adjustment mechanism B800 has at least a first locked state and a second locked state. In some other alternative embodiments, the number of the first matching parts B812 is at least two, and the number of the second matching parts B822 is at least two, so that the adjustment mechanism B800 has at least three seat width adjustment gears, so that the child carrier B1000 can better meet the infant's riding width requirements. In some other alternative embodiments, one of the first matching parts B812 and the second matching parts B822 is one, and the other is multiple, which can also achieve multiple seat width adjustment gears of the adjustment mechanism B800.

[0305] Reference Fig.37 In this embodiment, the first adjustment belt B811 and the second adjustment belt B821 are woven fabrics respectively. The first matching portion B812 is, for example, a connecting buckle, which is fixed to the first adjustment belt B811 by, for example, sewing. The second matching portion B822 is, for example, a buttonhole provided through the second adjustment belt B821. In an alternative embodiment, the second matching portion B822 and the first matching portion B812 are, for example, snaps that can be buckled with each other. In another alternative embodiment, the second matching portion B822 is, for example, a hook, and the first matching portion B812 is, for example, a hook, which is suitable for hooking on the hook.

[0306] like Figure 36 to Figure 38As shown, two first adjustment members B810 and two second adjustment members B820 are at least partially located on the front of the bearing assembly B200. A shielding member B920 is also provided on the bearing assembly B200, and the shielding member B920 is connected to the front of the bearing assembly B200 to cover the first adjustment member B810 and the second adjustment member B820, so that the front of the child carrier B1000 is neater and more beautiful. At least a part of the shielding member B920 in the depth direction is not connected to the bearing assembly B200, so that an operating port B921 is formed between the shielding member B920 and the bearing assembly B200, thereby allowing the first adjustment member B810 and the second adjustment member B820 to be operated through the operating port. The size of the operating port is suitable for the user to put his hand in, so as to operate the first adjustment member B810 and the second adjustment member B820.

[0307] Embodiment 5

[0308] The fifth embodiment of the present disclosure provides a child carrier B1000, such as Fig.39 As shown, the child carrier B1000 includes a waist belt B120, a shoulder belt B110, a bearing assembly B200 connected to the waist belt B120 and the shoulder belt B110 respectively, and a leg support portion B230 connected to the bearing assembly B200. The shoulder belt B110 is arranged roughly along the depth direction of the bearing assembly B200. One side of the bearing assembly B200 is connected to the waist belt B120, and the side of the bearing assembly B200 away from the waist belt B120 is detachably connected to the shoulder belt B110. That is, the upper side of the bearing assembly B200 is connected to the shoulder belt B110, and the lower side of the bearing assembly B200 is connected to the waist belt B120. The part of the bearing assembly B200 close to the waist belt B120 forms a buttocks support portion B210, and the upper side of the bearing assembly B200 forms a trunk support portion B220. The leg support portion B230 is connected to the hip support portion B210 and together with the leg support portion B230 forms a seat portion B6 for supporting infants and young children. The leg support portion B230 can be switched between an expanded state and a folded state. When the leg support portion B230 is in an expanded state, the leg support portion B230 is away from the hip support portion B210 in the lateral width direction of the bearing assembly B200, so that the seat portion B6 has a larger width. When the leg support portion B230 is in a folded state, the leg support portion B230 moves closer to the hip support portion B210 in the lateral width direction of the bearing assembly B200, so that the seat portion B6 has a smaller width.

[0309] This embodiment is different from the aforementioned fourth embodiment in at least the following aspects.

[0310] like Fig.39 and Fig.40As shown, the first connection end B231 of one of the two leg support parts B230 is suitable for connecting with the first connection end B231 of the other of the two leg support parts B230 through the adjustment mechanism B800. The adjustment mechanism B800 includes a first adjustment member B810 and a second adjustment member B820. The first adjustment member B810 includes a first adjustment belt B811 and a first matching portion B812 arranged on the first adjustment belt B811. One end of the first adjustment belt B811 is connected to the movable end B231a of the first leg support part B230e, and the other end is a movable end and is provided with the first matching portion B812. The second adjustment member B820 includes a second adjustment belt B821 and a second matching portion B822 arranged on the second adjustment belt B821. One end of the second adjustment belt B821 is connected to the movable end B231a of the second leg support part B230f, and the other end is a movable end and is provided with the second matching portion B822.

[0311] Reference Fig.39 and Fig.40, a shielding member B920 is also provided on the bearing assembly B200, and the shielding member B920 is connected to the front of the bearing assembly B200 to cover the first adjustment member B810 and the second adjustment member B820, so that the front of the child carrier B1000 is neater and more beautiful. In this embodiment, the bearing assembly B200 and the shielding member B920 are also provided with a limiting channel B924 and an operating port B921 connected to the limiting channel B924, so as to operate the first adjustment member B810 and the second adjustment member B820 through the operating port B921. The operating port B921 is located between the two connecting ports of the limiting channel B924, that is, the operating port B921 is located in the approximate middle of the horizontal width direction of the bearing assembly B200 and the shielding member B920 and is connected to the limiting channel B924. The limiting channel B924 is formed between the shielding member B920 and the bearing assembly B200, or is formed in the shielding member B920, and the first operating assembly and the second operating assembly are respectively arranged in the limiting channel B924. The limiting channel B924 is formed as a channel that penetrates in the horizontal width direction. In this embodiment, the shielding member B920 is sewn on the bearing assembly B200. There are a first suture line B926 and a second suture line B927 between the shielding member B920 and the bearing assembly B200. The first suture line B926 is farther away from the waistband B120 than the second suture line B927 (that is, the second suture line B927 is located below the first suture line B926). The limiting channel B924 is formed between the first suture line B926 and the second suture line B927 to limit the first adjustment member B810 and the second adjustment member B820 in the limiting channel B924. The first suture line B926 and the second suture line B927 extend linearly in the horizontal width direction. The first suture line B926 includes at least two non-continuous line segments, and an operation port B921 is formed between the two adjacent line segments. In this embodiment, the operation port B921 is located on the side of the bearing assembly B200 and the shielding member B920 close to the trunk support portion B220.

[0312] Embodiment 6

[0313] The sixth embodiment of the present disclosure provides a child carrier B1000, such as Fig.41As shown, the child carrier B1000 includes a waist belt B120, a shoulder belt B110, a bearing assembly B200 connected to the waist belt B120 and the shoulder belt B110 respectively, and a leg support portion B230 connected to the bearing assembly B200. The shoulder belt B110 is arranged roughly along the depth direction of the bearing assembly B200. One side of the bearing assembly B200 is connected to the waist belt B120, and the side of the bearing assembly B200 away from the waist belt B120 is detachably connected to the shoulder belt B110. That is, the upper side of the bearing assembly B200 is connected to the shoulder belt B110, and the lower side of the bearing assembly B200 is connected to the waist belt B120. The part of the bearing assembly B200 close to the waist belt B120 forms a buttocks support portion B210, and the upper side of the bearing assembly B200 forms a trunk support portion B220. The leg support portion B230 is connected to the hip support portion B210 and together with the leg support portion B230 forms a seat portion B6 for supporting infants and young children. The leg support portion B230 can be switched between an expanded state and a folded state. When the leg support portion B230 is in an expanded state, the leg support portion B230 is away from the hip support portion B210 in the lateral width direction of the bearing assembly B200, so that the seat portion B6 has a larger width. When the leg support portion B230 is in a folded state, the leg support portion B230 moves closer to the hip support portion B210 in the lateral width direction of the bearing assembly B200, so that the seat portion B6 has a smaller width.

[0314] There are at least the following differences between this embodiment and the child carrier B1000 in the aforementioned third embodiment.

[0315] like Figure 41 to Figure 44 As shown, the child carrier B1000 is also provided with an adjustment mechanism B800, which is provided on the leg support portion B230 to allow the leg support portion B230 to switch between an expanded state and a folded state through the adjustment mechanism B800, thereby adjusting the width of the seat portion B6. The adjustment mechanism B800 has an open state and a locked state. When the adjustment mechanism B800 is in the open state, the leg support portion B230 is in a folded state, the outer edge B236 of the leg support portion B230 is extended, at least a portion of the outer edge B236 of the leg support portion does not generate a supporting force, a portion of the leg support portion B230 and the hip support portion B210 together form the seat portion B6, and the effective width of the leg support portion B230 is reduced, so that the seat portion B6 has a smaller width. When the adjustment mechanism B800 is in a locked state, the leg support portion B230 is in an expanded state, and the outer edge B236 of the leg support portion is shortened. The outer edge B236 of the leg support portion is suitable for generating a supporting force to support an infant riding on the child carrier B1000. The leg support portion B230 and the hip support portion B210 together form a seat portion B6. The effective width of the leg support portion B230 is increased, thereby making the seat portion B6 have a larger width.

[0316] There are two leg support parts B230, and each leg support part B230 is provided with an adjustment mechanism B800. For ease of description, one leg support part B230 and the adjustment mechanism B800 configured on the leg support part B230 are used as an example for description.

[0317] like Fig.42 and Fig.43 As shown, the leg support portion B230 includes a main body piece B230a and an adjustment piece B230b. One end of the main body piece B230a is formed as a first connection end B231, and the other end of the main body piece B230a is formed as a second connection end B232. The first connection end B231 is connected to the bearing assembly B200, and the second connection end B232 is connected to the bearing assembly B200 or the waist belt B120. A portion of the adjustment piece B230b close to the second connection end B232 is directly connected to the main body piece B230a, and another portion of the adjustment piece B230b close to the first connection end B231 (i.e., the adjustment portion B230b1 of the adjustment piece B230b) is connected to the main body piece B230a through a connecting piece B230c.

[0318] Optionally, the leg support portion B230 further includes a connecting piece B230c, which is connected to at least one of the main body piece B230a and the adjustment piece B230b and shields the adjustment mechanism B800. Fig.42 and Fig.43 , the tab B230c is connected to the main body piece B230a and the adjustment piece B230b respectively. The tab B230c shields the adjustment mechanism B800 from the back of the child carrier B1000 to prevent the adjustment mechanism B800 from interfering with the child riding in the carrier 1000. In some alternative embodiments, the tab B230c is connected to one of the main body piece B230a and the adjustment piece B230b, and extends toward the other of the main body piece B230a and the adjustment piece B230b. It should be noted that "the connecting piece B230c is connected to one of the main piece B230a and the adjustment piece B230b" can be understood as: the connecting piece B230c is integrally formed with one of the main piece B230a and the adjustment piece B230b, or is fixedly connected to one of the main piece B230a and the adjustment piece B230b by means such as sewing, or is detachably connected to one of the main piece B230a and the adjustment piece B230b by means of zippers, snaps, etc.

[0319] The adjustment mechanism B800 includes a first adjustment member B810 provided on the adjustment sheet B230b and a second adjustment member B820 provided on the main sheet B230a. The first adjustment member B810 is provided at the adjustment portion B230b1 of the adjustment sheet B230b.

[0320] When the first adjustment member B810 and the second adjustment member B820 cooperate with each other (that is, the adjustment mechanism B800 is in a locked state), the connecting piece B230c is folded, and the adjustment piece B230b is connected to the main piece B230a in the depth direction to support the thigh. In this way, the seat portion B6 has a larger width.

[0321] When the first adjustment member B810 and the second adjustment member B820 are separated from each other, the connecting piece B230c naturally extends, and at least the portion of the adjustment piece B230b provided with the second adjustment member B820 is not connected to the main piece B230a and cannot provide support for the thigh. In this way, only a part of the leg support part B230 and the hip support part B210 form the seat part B6 together, so that the seat part B6 has a smaller width.

[0322] That is to say, in this embodiment, the width of the seat B6 can be changed by adjusting the width of the leg support B230 that can be used to provide supporting force (that is, the effective width of the leg support B230) through the adjustment mechanism B800, thereby meeting the requirements of the seat B6 width for children of different body shapes and different sitting methods.

[0323] The first adjustment member B810 includes a first matching portion B811. The second adjustment member B820 includes a second matching portion B812. The first matching portion B811 is suitable for matching with the second matching portion B812 so that the adjustment mechanism switches between a locked state and an open state. The first matching portion B811 and the second matching portion B812 are, for example, zippers that can be pulled together. Specifically, the first matching portion B811 is fixed on the adjustment piece B230b, for example, by sewing, and the second matching portion B812 is fixed on the main body piece B230a, for example, by sewing. In this embodiment, the second matching portion B812 is arranged on the front side of the main body piece B230a (that is, the side of the main body piece B230a facing away from the infant), and is located near the contact piece B230c. The first matching portion B811 extends roughly along the depth direction on at least a portion of the adjustment piece B230b, and the second matching portion B821 extends roughly along the depth direction on at least a portion of the main body piece B230a. In this embodiment, the first mating portion B811 roughly extends over half of the adjustment piece B230b, that is, the lower end of the first mating portion B811 is roughly located in the longitudinal middle of the adjustment piece B230b; the second mating portion B821 roughly extends over half of the main body piece B230a, that is, the lower end of the second mating portion B821 is roughly located in the longitudinal middle of the main body piece B230a.

[0324] The operating principle of the child carrier B1000 in this embodiment is as follows.

[0325] When the required width of the seat B6 is relatively large, the adjustment mechanism B800 is kept in a locked state (that is, the first matching part B811 and the second matching part B821 are pulled together). At this time, due to the pulling action of the first matching part B811 and the second matching part B821, the part where the adjustment piece B230b is pulled together (the part where the first matching part B811 is provided) also has a certain support strength, which can provide support for the child to sit. At this time, most or even all of the leg support part B230 can provide support, so that the effective width of the leg support part B230 is large, and then the width of the seat B6 is relatively large. At this time, in the case where the elastic part B7 is provided, the width of the seat B6 of the child carrier B1000 can be further adjusted. The adjustment principle and method are the same as those in the first embodiment above, and will not be repeated here.

[0326] When the required width of the seat B6 is relatively small, the adjustment mechanism B800 is switched to the open state (i.e., the first matching part B811 and the second matching part B821 are pulled apart). At this time, the first matching part B811 and the second matching part B821 no longer provide supporting strength for the opened part of the adjustment piece B230b (the adjustment part B230b1 provided with the first matching part B811), and at least a part of the leg support part B230 cannot provide supporting force, so that the effective width of the leg support part B230 is smaller, and thus the width of the seat B6 is relatively small.

[0327] In a variation of this embodiment, the leg support portion B230 includes a main body piece B230a, an adjustment piece B230b and a connecting piece B230c, the connecting piece B230c is connected between the main body piece B230a and the adjustment piece B230b and can be switched between an unfolded position and a folded and retracted position, and the upper end of the adjustment piece B230b is fixedly connected to the hip support portion B210 or the main body piece B230a. The child carrier B1000 also includes an adjustment mechanism 800 disposed on the leg support portion B230, and the adjustment mechanism B800 includes a first adjustment member B810 disposed on the adjustment piece B230b and a second adjustment member B820 disposed on the main body piece B230a. When the first adjustment member B810 is not connected to the second adjustment member B820, the connecting piece B230c is in an unfolded state; when the first adjustment member B810 is connected to the second adjustment member B820, the connecting piece B230c is in a folded and retracted state. When the required width of the seat B6 is relatively large, the adjustment mechanism B800 is kept in the open state (that is, the first matching part B811 and the second matching part B821 are kept pulled apart), and the connecting piece B230c is unfolded at this time, and both the adjustment piece B230b and the connecting piece B230c can provide support, so that the width of the seat B6 is relatively large; and when the required width of the seat B6 is relatively small, the adjustment mechanism B800 is switched to the locked state (that is, the first matching part B811 and the second matching part B821 are pulled together), and the adjustment piece B230b can provide support, while the connecting piece B230c cannot provide support due to folding and contraction, so that the width of the seat B6 is relatively small.

[0328] Embodiment 7

[0329] The seventh embodiment of the present disclosure provides a child carrier B1000, such as Figure 45 to Figure 47 As shown, the child carrier B1000 includes a waist belt B120, a shoulder belt B110, a bearing assembly B200 connected to the waist belt B120 and the shoulder belt B110 respectively, and a leg support portion B230 connected to the bearing assembly B200. The shoulder belt B110 is arranged roughly along the depth direction of the bearing assembly B200. One side of the bearing assembly B200 is connected to the waist belt B120, and the side of the bearing assembly B200 away from the waist belt B120 is detachably connected to the shoulder belt B110. That is, the upper side of the bearing assembly B200 is connected to the shoulder belt B110, and the lower side of the bearing assembly B200 is connected to the waist belt B120. The part of the bearing assembly B200 close to the waist belt B120 forms a buttocks support portion B210, and the upper side of the bearing assembly B200 forms a trunk support portion B220. The leg support portion B230 is connected to the hip support portion B210 and together with the leg support portion B230 forms a seat portion B6 for supporting an infant.

[0330] This embodiment is different from the third embodiment described above in at least the following aspects.

[0331] like Figure 45 to Figure 47 As shown, the leg support part B230 is in the unfolded state (refer to Fig.45 and Fig.47 ) and collapsed state (refer to Fig.46 ) are switchable between the two positions. When the leg support portion B230 is in the unfolded state, the outer edge B236 of the leg support portion is at a greater distance from the hip support portion B210 in the lateral width direction of the bearing assembly B200, so that the seat portion B6 has a larger width. When the leg support portion B230 is in the folded state, the outer edge B236 of the leg support portion is close to the hip support portion B210 in the lateral width direction of the bearing assembly B200, so that the seat portion B6 has a smaller width. There are two leg support portions B230, and the two leg support portions B230 are symmetrically arranged on the left and right sides of the hip support portion B210. Each leg support portion B230 includes a first side B238 close to the hip support portion B210 and a second side B239 away from the hip support portion B210. The second side B239 forms the outer edge B236 of the leg support portion. Among them, the first side B238 is connected to the hip support portion B210 by, for example, sewing. The child carrier B1000 is provided with an adjustment mechanism B800 for adjusting the position of the outer edge B236 of the leg support portion relative to the hip support portion B210 so as to switch the leg support portion B230 between an expanded state and a collapsed state, thereby adjusting the width of the seat portion B6.
