[0050] As Figure 3 and Figure 4As shown, the rear end of the shoulder strap 11 and one end of the waist part 13 are in a webbing structure 114, and the rear end of the shoulder strap 11 is detachably connected to the middle part of the support sheet 2 by means of a second fixing buckle 112 which is adjustable in length and can be docked and engaged. The two ends of the waist part 13 are detachably connected by means of a third fixing buckle 131 which is adjustable in length and can be docked and engaged. Specifically, the second fixing buckle 112 comprises a male buckle 112a and a female buckle 112b which is docked and engaged with the male buckle 112a, and the rear end of each shoulder strap 11 is connected to a male buckle 112a through a grommet 113. The length of the shoulder strap 11 is adjusted by sliding the grommet 113 on the webbing structure 114, and the female buckle 112b which is docked and engaged with the male buckle 112a is fixed to the two sides of the middle part of the support sheet 2. The detachable connection of the rear end of the shoulder strap 11 to the middle part of the support sheet 2 is achieved by the docking and engagement of the male buckle 112a and the female buckle 112b. The third fixing buckle 131 comprises a male buckle 131a and a female buckle 131b which is docked and engaged with the male buckle 131a, and one end of the waist part 13 is connected to a male buckle 131a through a grommet 113. The length of the waist part 13 is adjusted by sliding the grommet 113 on the webbing structure 114, and the female buckle 131b which is docked and engaged with the male buckle 131a is fixed to the other end of the waist part 13. The detachable connection of the two ends of the waist part 13 is achieved by the docking and engagement of the male buckle 131a and the female buckle 131b. Of course, the second fixing buckle 112 and the third fixing buckle 131 can also be convenient and practical buckles such as plug-in buckles, snaps, magic tapes, fixing buckles and fixing holes.

[0051] In combination Figure 4 and Figure 5 As shown, the waist part 13 of the present application is provided with an adjusting fixing buckle 132 at the connection with the lower part of the support sheet 2 for adjusting the width and height of the support sheet 2. The adjusting fixing buckle 132 has a buckled state and a released state, and the width and height of the support sheet 2 are smaller when the adjusting fixing buckle 132 is in the buckled state than when the adjusting fixing buckle 132 is in the released state. As shown Figure 4 When the adjusting fixing buckle 132 is in the released state, the width and height of the lower part of the support sheet 2 are larger, and it can cover babies with larger body shapes.

More specifically, the adjusting fastener 132 consists of a drawstring 1321, a matching button 1322, and a retaining ring 1323. When the button 1322 is engaged within the retaining ring 1323, the drawstring 1321 pulls the support piece 2 to fold, reducing its width and height. When the button 1322 disengages from the retaining ring 1323, the support piece 2 returns to its original width and height. Alternatively, the adjusting fastener 132 can be a snap fastener, snap button, or Velcro, offering convenience and practicality. This adjusting fastener 132 can adaptively adjust the width and height of the support piece 2 according to the changing body shape of infants at different ages, better fitting the infant's body shape, especially providing more stable support for the infant's buttocks and legs, thus providing a safer and more comfortable riding experience.

[0052] The shoulder straps 11 of the baby carrier 100 of the present invention are crossed at the user's back by the shoulder strap fixing member 12. This crossed structure not only effectively distributes the load on the shoulders to the user's back, but also effectively prevents the shoulder straps 11 from slipping, improving the stability and firmness of the front-carrying carrier and ensuring that the baby is kept in a more stable position, thereby ensuring the baby's safety. On the other hand, the baby carrier 100 of the present invention adjusts the crossing position of the two shoulder straps 11 by sliding the shoulder strap fixing member 12. Users with different shoulder widths and heights can make adaptive adjustments to the crossing position of the two shoulder straps 11 according to their own actual situation, so that the crossing position of the two shoulder straps 11 can be adjusted and fixed at a load-bearing position suitable for the user's own conditions, thereby allowing the user's shoulders, back and waist to bear the force evenly at the same time, reducing the user's shoulder burden and delaying the time when the user feels fatigued.

[0053] like Figures 9-11 As shown, in the second embodiment of the present invention, the upper part of the support piece 2 and the front ends of the two shoulder straps 11' are integrally formed. The two ends of the upper part of the support piece 2 extend independently to form two shoulder straps 11'. In use, the two shoulder straps 11' are wrapped around to the front and detachably connected to the middle of the support piece 2 by a second fixing buckle 112 that is adjustable in length and can engage. Of course, the upper part of the support piece 2 and the front ends of the two shoulder straps 11' can also be fixedly connected by sewing to form an integral structure, but the method of achieving an integral structure between the upper part of the support piece 2 and the front ends of the two shoulder straps 11' is not limited to this. This integral structure reduces the use of buckle assemblies, making the overall structure of the baby carrier 100 simpler and easier to store and carry.

[0054] like Figures 12-14As shown, the carrying assembly 1 of the third embodiment of the present application further comprises a transition buckle 133, a sliding buckle 15 and a side shoulder strap 14, the transition buckle 133 is connected to the waist part 13, the rear end of the shoulder strap part 11 is connected to the middle part of the support sheet 2 by changing direction through the transition buckle 133, the sliding buckle 15 is slidably arranged on the rear end of the shoulder strap part 11, the sliding buckle 15 is connected to the rear end of the side shoulder strap 14, the front end of the side shoulder strap 14 is connected to the upper part of the support sheet 2, and the rear end of the side shoulder strap 14 is slidably connected to the rear end of the shoulder strap part 11 through the sliding buckle 15; specifically, the side shoulder strap 14 is in an integrated structure with the support sheet 2. The rear end of the shoulder strap part 11 is transitionally connected to the waist part 13 through the transition buckle 133, so that the force bearing area of the shoulder strap part 11 on the back of the user is larger, further reducing the burden on the shoulders and waist of the user, so that the shoulders, back and waist of the user are more balancedly stressed at the same time; the side shoulder strap 14 further strengthens the connection between the support sheet 2 and the shoulder strap part 11, effectively preventing the baby from sliding off from the side of the baby carrier 100, thereby further ensuring the safety of the baby; specifically, the rear end of the shoulder strap part 11 is in a webbing structure 114, and the webbing structure 114 is slidably arranged through the waist part 13.

[0055] In combination Figures 1-14 As shown, the shoulder strap part 11 of the baby carrier 100 of the present application is crossed on the back of the user through the shoulder strap fixing part 12, which well disperses the load on the shoulders to the back of the user, effectively prevents the shoulder strap part 11 from sliding off, improves the stability and firmness of the front-back type carrier, ensures that the baby remains in a more stable position, thereby ensuring the safety of the baby; on the other hand, the baby carrier 100 of the present application adjusts the crossing position of the two shoulder strap parts 11 through the sliding of the shoulder strap fixing part 12, so that users with different shoulder widths and different heights can adaptively adjust the crossing position of the two shoulder strap parts 11 according to their actual conditions, so that the shoulders, back and waist of the user are balancedly stressed at the same time, reducing the burden on the shoulders of the user, and delaying the time when the user feels tired; through the engagement of the male buckle and the female buckle of the first fixing buckle 111, the second fixing buckle 112 and the third fixing buckle 131, the quick disassembly and separation between the parts are realized, so that the operation of carrying the baby with the baby carrier 100 is more convenient and fast, and the adjustment fixing buckle 132 can adaptively adjust the width and height of the support sheet 2 according to the changes of the body shape of the baby at different age stages, so that the universality of the baby carrier 100 is stronger.
