[0033] Embodiments of the present invention will now be described with reference to the accompanying drawings, wherein like reference numerals represent like elements throughout the several views.

[0034] First combine Figure 1-Figure 8 As shown, a baby carrier 100 provided by the present invention includes a waist belt 110, a vest 120 and a back bag 130 respectively connected to the waist belt 110. The waist belt 110 and the vest 120 are used for being worn by a user. At the same time, the vest 120 and the back bag 130 are detachably connected to form a riding space for infants and young children to ride therebetween.

[0035] See also Figure 1-Figure 8 As shown, the vest 120 includes a back connecting piece 121, two shoulder straps 122, and two connecting straps 123. The two shoulder straps 122 are symmetrically connected to one end of the back connecting piece 121, and one end of each shoulder strap 122 away from the back connecting piece 121 is connected to the waist belt 110, and a head wearing space 124 is formed between the two shoulder straps 122 and the back connecting piece 121 (see FIG. Figure 3-4 , Figure 7-8 The two connecting straps 123 are symmetrically connected to the other end of the back connecting piece 121, and the end of each connecting strap 123 away from the back connecting piece 121 is detachably connected to the waist belt 110 or the backpack 130, and an arm wearing space 125 is formed between the connecting strap 123 and the shoulder strap 122 (see Figure 3-4 , Figure 7-8The vest 120 is connected to the shoulder straps 122 and the connecting belt 123 on the left and right sides through the back connecting piece 121. During use, the two shoulder straps 12 are pulled by the back connecting piece 121 to prevent them from sliding down along the user's arms, making the use process more convenient and labor-saving.

[0036] In the present invention, the back connecting piece 121, the shoulder straps 122, and the connecting belt 123 of the vest 120 may be an integrally formed structure, or may be formed separately and then sewn and fixed.

[0037] Continue to view Figure 1-Figure 6 As shown, in the baby carrier 100 of the present invention, the shoulder strap 122 is detachably connected to the top of the back bag 130 via a first connecting structure 140, specifically forming the riding space between the shoulder strap 122 and the back bag 130; at the same time, the connecting belt 123 is detachably connected to the waist belt 110 or the back bag 130 via a second connecting structure 150.

[0038] like Figure 4-6 As shown, the first connection structure 140 includes a first connection member 141 and a second connection member 142 that are detachably connected. One of the first connection member 141 and the second connection member 142 is connected to the shoulder strap 122, and the other of the first connection member 141 and the second connection member 142 is connected to the top of the backpack 130. In a specific embodiment, the first connection member 141 is fixed to the two shoulder straps 122, and at the same time, the top of the backpack 130 is protrudingly provided with first connection ends 1311 on both sides of the horizontal width direction, and each first connection end 1311 is adjustably connected to the second connection member 142. After the first connection member 141 and the second connection member 142 are connected, the height of the backpack 130 and the size of the riding space can be adjusted by adjusting the position of the second connection member 142.

[0039] Combination Figure 1 , Figure 4-6As shown, the second connection structure 150 includes a detachably connected third connection member 151 and a fourth connection member 152, one of which is fixed to or adjustably connected to the connection belt 123, and the other of which is fixed to or adjustably connected to the backpack 130 or the waist belt 110. In a specific embodiment, the third connection member 151 is adjustably connected to the connection belt 123. Specifically, the second connection structure 150 also includes a first adjustment buckle 153 fixed to the connection belt 123 and a first adjustment belt 154 passed through the first adjustment buckle 153. One end of the first adjustment belt 154 is connected to the third connection member 151. When the other end of the first adjustment belt 154 is pulled to move along the first adjustment buckle 153, the position of the third connection member 151 can be adjusted; the fourth connection member 152 is fixed to the backpack 130. When the third connecting member 151 and the fourth connecting member 152 are connected, the overall length of the shoulder straps 122 and the connecting straps 123 can be adjusted by pulling the first adjusting belt 154, that is, the position of the back connecting piece 121 can be adjusted so that the vest 120 can adapt to different users.

[0040] It is understandable that connecting the fourth connecting member 152 to the waist belt 110 does not affect the realization of the function of the vest 120 .

[0041] In the present invention, the first connector 141 and the second connector 142 are preferably male and female buckles of detachable magnetic buckles, which can easily realize the detachable connection between the backpack 130 and the shoulder strap 122, and are more stable when connected. Of course, the first connector 141 and the second connector 142 can also be matching buckles, snaps, buttons, zippers or Velcro, etc. At the same time, the third connector 151 and the fourth connector 152 are preferably male and female buckles of detachable plug-in buckles, which make the connection and disassembly operations more convenient. Among them, the third connector 151 and the fourth connector 152 can also be matching magnetic buckles, buckles, snaps, buttons, zippers or Velcro, etc. The first connection structure 140 and the second connection structure 150 are not limited to the aforementioned connection structures, and other connectors can also be used to achieve detachable connection.

[0042] Continue to view Figure 1-Figure 6 As shown, the baby holding carrier 100 of the present invention has a waist belt 110 including a waist belt body 111 and a waist guard plate 112. The two ends of the waist belt body 111 are detachably connected via a third connecting structure 160. The waist guard plate 112 can be connected to the waist belt body 111 or be independently provided. When the two ends of the waist belt body 111 are connected via the third connecting structure 160, the waist guard plate 112 is padded between the third connecting structure 160 and the user's waist to increase the force-bearing area for more comfortable use.

[0043] Combination Figure 3-Figure 6 As shown, in one embodiment of the present invention, the waist guard plate 112 is adjustably connected to one end of the waist belt body 111 , and the waist guard plate 112 and the other end of the waist belt body 111 are detachably connected via a third connecting structure 160 . Specifically, the third connection structure 160 includes a detachably connected fifth connection member 161, a sixth connection member 162, a second adjustment buckle 163 fixed to the waist guard plate 112, and a second adjustment belt 164 inserted into the second adjustment buckle 163. One end of the second adjustment belt 164 is connected to one end of the waist belt body 111, and the other end protrudes out of the second adjustment buckle 163. By pulling the second adjustment belt 164 to move along the second adjustment buckle 163, the position between the waist guard plate 112 and the waist belt body 111 can be adjusted. At the same time, the fifth connection member 161 is adjustably connected to the other end of the waist belt body 111 through the third adjustment belt, and the sixth connection member 162 is fixed to the waist guard plate 112. Of course, the positions of the fifth connection member 161 and the sixth connection member 162 are interchangeable. When the fifth connection member 161 and the sixth connection member 162 are connected, the connection of the waist belt body 111 can be realized, and then the position of the fifth connection member 161 and the position of the waist guard plate 112 can be adjusted to adapt to different users.

[0044] Preferably, the fifth connecting member 161 and the sixth connecting member 162 are male and female buckles of plug-in buckles, but are not limited thereto. For example, they may be any one of matching magnetic buckles, snaps, buttons, zippers, and Velcro.

[0045] Combine again below Figure 1-6 As shown, the baby carrier 100 of the present invention has a back bag 130 including a back support portion 131, a hip support portion 132 and two leg support portions 133. The hip support portion 132 is fixed to the waist belt body 111, and the two leg support portions 133 are symmetrically arranged on both sides of the hip support portion 132 in the horizontal width direction, and both can be folded relative to the hip support portion 132 to jointly enclose a seating space for infants and young children to sit on; the back support portion 131 is arranged above the hip support portion 132, and the top of the back support portion 131 is detachably connected to the shoulder strap 122.

[0046] See also Figure 1 , Figure 4-6As shown, in the present invention, the top of the back support part 131 is respectively provided with the aforementioned first connection ends 1311, and the two first connection ends 1311 both extend upward from the back support part 131. At the same time, the back support part 131 is also provided with two second connection ends 1312, and the two second connection ends 1312 are respectively provided above the two leg support parts 133, and the fourth connection member 152 is fixed to the second connection ends 1312. In this way, when the connection belt 123 is connected to the fourth connection member 152, a space for the thighs of infants and young children to extend is formed between the connection belt 123, the second connection ends 1312 and the leg support parts 133, thereby limiting the sliding of infants and young children to the side, and ensuring their safety and comfort when riding.

[0047] Combine the following Figure 1 , Figure 7 As shown, the backpack 130 further includes a neck guard 134, which is foldably connected to the top of the back support portion 131 and is located between the two first connection ends 1311. The neck guard 134 has a first position and a second position. Figure 7 The figure shows the state where the neck guard piece 134 is in the first position, in which the neck guard piece 134 extends upward along the back support portion 131, and is used to strengthen the support for the neck and head of the infant and young child, thereby improving the comfort and safety of riding. When the neck guard piece 134 is folded downward and overlapped on the back support portion 131, it is in the second position, so that the neck guard piece 134 has an optional non-use position, which is more flexible and convenient to use.

[0048] In one embodiment of the present invention, the neck guard piece 134 is fixed to the top of the back support part 131 and can be folded along the connection line between the two. At the same time, matching connection holes and connection buckles are provided between the two ends of the neck guard piece 134 and the back support part 131, and the connection holes and connection buckles at each end can be provided with only one pair or multiple pairs arranged along the longitudinal direction of the back bag 130. In this embodiment, each end of the neck guard piece 134 is provided with a connection hole 1341, and each side of the back support part 131 is provided with multiple connection buckles 1313 arranged along the longitudinal direction of the back bag 130, and there are two in this embodiment. When the neck guard piece 134 is in the first position, the connection hole 1341 can be buckled onto the upper connection buckle 1313 to fix the position of the neck guard piece 134 (see Figure 1 , Figure 7 ), when the neck guard piece 134 is folded toward the bottom of the back bag 130 and is in the second position, the connecting hole 1341 can be fastened to the connecting buckle 1313 below (see Figure 7 ) to fix its position.

[0049] In this embodiment, the connecting buckle 1313 is preferably a button, but is not limited thereto. For example, the neck guard 134 and the back support portion 131 can also be fixed by magnetic buckles, snaps, Velcro, zippers, straps, etc.

[0050] Continue to combine Figure 1 , Figure 7 As shown, in the baby carrier 100 of the present invention, the hip support portion 132 of the back bag 130 is further provided with an adjustment structure 170, which is used to adjust the width and / or height of the hip support portion 132 to accommodate infants of different body shapes or different sitting styles. In one embodiment, the adjustment structure 170 includes an adjustment member 171 arranged along the lateral width direction of the back bag 130 and having at least one adjustment section, and the adjustment member 171 is used to adjust the width of the hip support portion 132.

[0051] More specifically, there is at least one adjusting member 171, and at least one end of each adjusting member 171 is detachably connected to the hip support portion 132 and extends along the lateral width direction of the backpack 130. Each adjusting member 171 has at least one adjustment section. The width of the hip support portion 132 is adjusted by buckling the adjusting member 171 at different sections. Moreover, the width of the hip support portion 132 when the adjusting member 171 is buckled is smaller than that when the adjusting member 171 is released.

[0052] like Figure 1 , Figure 7 As shown, in this embodiment, there are two adjusting members 171, one end of each adjusting member 171 is fixed to one side of the hip support portion 132 in the width direction, and in this embodiment, it is fixed at the connection position of the hip support portion 132 and the leg support portion 133. At the same time, the other end of each adjusting member 171 is also provided with at least one fixing hole, and the distance from the fixing hole to the fixing end of the adjusting member 171 is smaller than the width of the hip support portion 132. The two adjusting members 171 are symmetrically arranged along the width direction of the hip support portion 132. At the same time, the adjusting structure 170 also includes at least one fixing buckle 172 fixed to the hip support portion 132. In this embodiment, two fixing buckles 172 are arranged at intervals, and the two fixing buckles 172 are fixed to the approximately middle part of the hip support portion 132 in the width direction. In this way, when the fixing hole of each adjusting member 171 is buckled on the corresponding fixing buckle 172, the width of the hip support portion 132 is smaller than when the fixing hole is separated from the fixing buckle 172. Of course, the setting positions of the fixing hole and the fixing buckle 172 can be interchanged; at the same time, both ends of the adjustment member 171 can be set as a detachable connection structure, which can also achieve the width adjustment of the hip support part 132.

[0053] It is understandable that the adjustment member 171 is not limited to two. Only one adjustment member 171 is provided, and at least one end of the adjustment member 171 is detachably connected to the hip support portion 132, so that the width of the hip support portion 132 can also be adjusted. In addition, the adjustment member 171 and the hip support portion 132 can also be connected in other ways, for example, they can also be connected by matching buckles, Velcro, zippers, straps, buttons, snaps, etc.

[0054] Combine again below Figure 1-8 As shown, when the baby carrier 100 of the present invention is used, the first connecting member 141 and the second connecting member 142 are buckled together, and the third connecting member 151 and the fourth connecting member 152 are buckled together to achieve the connection between the vest 120 and the backpack 130. The head wearing space 124 between the back connecting piece 121 of the vest 120 and the two shoulder straps 122 is provided for the user to wear the head (see Figure 7 ), the arm wearing space 125 between the shoulder strap 122 and the connecting strap 123 (see Figure 3-4 , Figure 7 ) for the user to wear on his / her arms, and a space for infants to sit is formed between the vest 120 and the backpack 130, such as Figure 7 As shown. When the user wears the waist belt 110 and the vest 120, the user can pull the first adjustment belt 154 to move it along the first adjustment buckle 153 to adjust the position of the back connecting piece 121 according to the needs, that is, adjust the overall length of the shoulder strap 122 and the connecting end 123 to adapt to the user; at the same time, the fifth connecting member 161 and the sixth connecting member 162 are connected, and the waist belt body 111 and the waist guard plate 112 are arranged around the waist of the user, and the waist guard plate 112 is arranged between the fifth connecting member 161, the sixth connecting member 162 and the waist of the user, and then the position of the waist guard plate 112 is adjusted by adjusting the position of the fifth connecting member 161 and by pulling the second adjustment belt 164 to move it along the second adjustment buckle 163, so that the waist belt 110 can adapt to different users, wherein the setting of the waist guard plate 112 can increase the force-bearing area, thereby making the process of carrying infants and young children more comfortable.

[0055] In addition, the width of the hip support portion 122 can be adjusted by engaging the adjusting member 171 with the fixing buckle 172 or releasing the engagement according to different infants or different sitting styles of infants. For example, when the infant is sitting with his back to the caregiver, the adjusting member 171 is engaged with the fixing buckle 172 to reduce the width of the hip support portion 122, thereby making the infant sit more comfortably. Correspondingly, when the infant is sitting facing the caregiver, his hips are wider, and the engagement of the adjusting member 171 with the fixing buckle 172 is released to increase the width of the hip support portion 132, thereby making the infant sit more comfortably.

[0056] In summary, the baby carrier 100 of the present invention has a vest 120 including a back connecting piece 121 and two shoulder straps 122 and two connecting belts 123 connected to the back connecting piece 121. One end of the two shoulder straps 122 away from the back connecting piece 121 is connected to the waist belt 110, and one end of the two connecting belts 123 away from the back connecting piece 121 is detachably connected to the back bag 130 or the waist belt 110. An arm wearing space 125 is formed between the shoulder straps 122 and the connecting belts 123. The shoulder straps 122 and the connecting belt 123 on the left and right sides are connected. During use, the back connecting piece 121 has a pulling effect on the shoulder straps 122 on the left and right sides, which can prevent the shoulder straps 122 from sliding down along the user's arms, thereby reducing unnecessary pulling and adjustment of the shoulder straps 122, making it more convenient to use. At the same time, it can ensure the balance of force on both sides, thereby ensuring the comfort of infants and young children. In addition, the back connecting piece 121 can distribute the force to the user's back, thereby reducing the force on his shoulders, so it is more labor-saving during use.

[0057] The structures and connection methods of other parts of the baby carrier 100 involved in the present invention are conventional settings well known to ordinary technicians in the field and will not be described in detail here.

[0058] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
