[0002] Infant carriers, such as safety baskets and safety seats, generally consist of a seat portion and a backrest portion. In order to improve the comfort of infants and young children when riding in the carrier, the backrest portion is usually pivoted relative to the seat portion, so that the angle between the two can be adjusted according to needs, so that the infant and young children can sit or lie in the carrier. However, currently common infant carriers cannot meet the different riding posture requirements of infants and young children of different age groups, such as sitting, reclining and lying, etc., which will reduce the riding comfort of infants and young children and is not conducive to the promotion of infant carriers. Although some infant carriers (such as safety seats) on the market have an adjustable inclination angle between the backrest portion and the seat portion, the structure of the angle adjustment mechanism set inside is relatively complex, and it is easy to get stuck during adjustment, which is inconvenient to operate, resulting in poor stability of the angle adjustment of the infant carrier, and too many parts will lead to the problem of excessive weight, affecting the user experience.

In this first embodiment, the legrest portion 150 and the shell 110 are an integrally formed structure. In other embodiments, the legrest portion 150 and the shell 110 may also be fixedly connected by screwing, riveting or welding. The backrest portion 200 has at least two angular positions relative to the shell 110 to adapt to different seating needs of infants, such as sitting and lying positions at different angles. For example, Figure 1 and 3 The first use state of the backrest portion 200 and the housing 110 is suitable for a lying state of an infant. Figure 4 and Figure 5 The second use state of the backrest 200 and the shell 110 is suitable for the situation where the infant is sitting. It should be understood that the angular positions of the backrest 200 and the shell 110 can also be set to more than two or less than two as needed, and the present invention is not limited to this. In addition, it should be understood that the correspondence between the first use state and the second use state of the backrest 200 and the shell 110 and the posture of the infant on the baby carrier 1000 is merely exemplary and does not necessarily correspond to the lying state of the infant and the sitting state of the infant, respectively. For example, the first use state can also be suitable for the sitting state of the infant, and the second use state can also be suitable for the lying state of the infant, and the like, and the present invention is not limited to this.

[0118] In some embodiments, when the backrest 200 of the baby carrier 1000 is adjusted relative to the shell 110 to a lying position suitable for the infant, the angle between the backrest and the horizontal direction is greater than the angle between the leg rest and the horizontal direction, so that the legs of the infant will not be higher than the head when lying flat, thereby improving the comfort of the infant when lying flat.

[0119] A snap-fitting member 800 is provided on one side of the seat portion 100 away from the seating space 300. The snap-fitting member 800 is mainly used to snap-fit ​​with the carrier base on the car seat so that the infant carrier can be stably fixed on the car seat. Specifically, the snap-fitting member 800 is a rod-shaped structure, which is fixedly connected to the bottom of the seat portion 100 by fasteners (screws or bolts, etc.) or is directly integrally formed on the bottom of the seat portion 100.

[0120] To facilitate users to carry the baby carrier, in some examples, such as Figure 1 and Figure 3 As shown, the infant carrier also includes a handle 7000, which is connected to the seat portion 100 or the backrest portion 200. Optionally, the handle 7000 is installed on the seat portion 100 or the backrest portion 200 in a detachable or non-detachable manner. In this first embodiment, the housing 110 is provided with a handle coupling portion 102 (see Figure 6 ), the handle 7000 is detachably pivoted to the handle joint portion 102 of the seat portion 100. In this way, when the baby carrier needs to be carried, the handle 7000 is rotated to be away from the seat portion 100 or the backrest portion 200, so that it is convenient for the user to hold it; when the baby carrier does not need to be carried, the handle 7000 is rotated to be close to the seat portion 100 or the backrest portion 200, so that the handle 7000 does not block the infant's field of vision, and it is convenient for the user to put the infant into the baby carrier or take the infant out of the baby carrier.

[0121] In the first embodiment, the seat portion 100 can also be pivotally connected to the backrest portion 200. In other embodiments, the seat portion 100 and the backrest portion 200 can also be fixedly connected, that is, the seat portion 100 and the backrest portion 200 cannot move relative to each other. Specifically, in the first embodiment, one end of the seat portion 100 is pivotally connected to one end of the backrest portion 200, that is, the angle between the two can be adjusted, so that the infant carrier can have at least two usage states. For example Figure 1 and Figure 3 The first use state shown (when the infant is in a lying position in the infant carrier) or Figure 4 and Figure 5Of course, at least one transition state can be set between the first use state and the second use state. In this way, the user can adaptively adjust the angle between the seat portion 100 and the backrest portion 200 according to the state of the infant (e.g., sleeping state, awake state), thereby improving the comfort of the infant in the infant carrier.

[0122] See also Figures 4 to 7 In some examples, the backrest portion 200 and the seat portion 100 are pivotally connected via the pivot structure 400. Specifically, the front end of the backrest portion 200 is pivotally connected to the rear end of the seat portion 100 via the pivot structure 400. More specifically, the pivot structure 400 includes a first pivot fitting portion, a second pivot fitting portion, and a matching connector. The first pivot fitting portion is disposed on one of the seat portion 100 and the backrest portion 200, and the second pivot fitting portion is disposed on the other of the seat portion 100 and the backrest portion 200. The seat portion 100 and the backrest portion 200 are pivotally connected via the first pivot fitting portion and the second pivot fitting portion. The matching connector pivotally connects the first pivot fitting portion and the second pivot fitting portion.

[0123] Specifically, the first pivoting fitting portion includes a pivoting member 420, the second pivoting fitting portion includes a pivoting seat 430, the pivoting seat 430 is provided with a first engaging groove 431, the matching connecting member includes a pivoting cover 440, the pivoting cover 440 is provided with a second engaging groove 441, the first engaging groove 431 and the second engaging groove 441 are combined to form a pivoting groove 410, at least part of the pivoting member 420 is inserted into the pivoting groove 410 and can rotate in the pivoting groove 410, so that the baby carrier 1000 can be switched between the first use state and the second use state. In this first embodiment, as shown in FIG. Figure 6 and Figure 7 As shown, the pivot seat 430 is disposed on the backrest portion 200 , and the pivot member 420 is disposed on the seat portion 100 .

[0124] It should be noted that the "front end" described herein refers to the end of the seat portion 100 away from the backrest portion 200, and the "rear end" refers to the end of the backrest portion 200 away from the seat portion 100. More specifically, the "front end" refers to the end of the infant carrier that is closer to the infant's feet, and the "rear end" refers to the end that is closer to the infant's head. In addition, unless otherwise clearly specified and limited, the "front", "rear", "left", "right" and other directions of the infant carrier (i.e., the infant carrier 1000) in each embodiment of the utility model can be represented by the arrows F, B, L, and R in the figure. These directional terms are only used to make the description of the embodiments of the utility model clearer, and are not used to improperly limit the scope of protection of the utility model.

[0125] See also Figures 6 to 10Specifically, the pivot cover 440 is detachably mounted on the pivot seat 430. For example, the pivot cover 440 is mounted on the pivot seat 430 by snap-fit ​​connection; or, the pivot cover 440 is mounted on the pivot seat 430 by threaded connection. Specifically, in the first embodiment, Figure 6 and Figure 8 As shown, the pivot seat 430 is provided with a first connecting hole 432, and the pivot cover 440 is provided with a second connecting hole 442. The pivot cover 440 and the pivot seat 430 are connected by connecting screws or fasteners such as connecting screws passing through the second connecting hole 442 and the first connecting hole 432 in sequence.

[0126] See also Figures 6 to 9 In some examples, the first engaging groove 431 and the second engaging groove 441 are both arc-shaped grooves. Figure 6 and Fig.10 As shown, the pivoting member 420 has an arcuate surface 421, and the curvature of the arcuate surface 421 matches the curvature of the groove wall of the pivoting groove 410. In this way, the smoothness of the pivoting member 420 rotating in the pivoting groove 410 can be improved. Specifically, in the first embodiment, the first engaging groove 431 and the second engaging groove 441 are both semicircular grooves, so that a circular pivoting groove 410 can be formed when the two are enclosed. Of course, in other alternative embodiments, the first engaging groove 431 and the second engaging groove 441 can be other arcuate grooves, as long as the first engaging groove 431 and the second engaging groove 441 are enclosed to form a complete circular pivoting groove 410. For example, when the first engaging groove 431 is a 2 / 3 arcuate groove, the second engaging groove 441 is a 1 / 3 arcuate groove.

[0127] In some examples, one of the pivot seat 430 and the pivot member 420 is integrally formed with the seat portion 100, and the other is integrally formed with the backrest portion 200. In other words, when the pivot seat 430 is integrally formed with the seat portion 100, the pivot member 420 is integrally formed with the backrest portion 200; and when the pivot seat 430 is integrally formed with the backrest portion 200, the pivot member 420 is integrally formed with the seat portion 100. Specifically, according to the foregoing, in the first embodiment, if Figure 8 and Fig.10As shown, the pivot seat 430 is integrally formed with the backrest portion 200, and the pivot member 420 is integrally formed with the seat portion 100. In this way, the structural strength of the pivot structure 400 is improved, thereby improving the reliability of the pivot. Of course, in other alternative embodiments, one of the pivot seat 430 and the pivot member 420 is detachably connected to the seat portion 100, and the other is detachably connected to the backrest portion 200. By integrally forming the pivot structure 400 with the seat portion 100 and the backrest portion 200, the pivot connection between the backrest and the seat is achieved, and there is no need to set a separate pivot shaft and pivot hole, thereby reducing the number of parts, which not only simplifies the lying function, but also makes the adjustment more stable and reliable, and the overall weight of the baby carrier is lighter.

[0128] In the first embodiment, the pivot seat 430 is located at one end of the backrest 200 close to the seat 100, that is, the front end of the backrest 200. The pivot member 420 is located at one end of the seat 100 close to the backrest 200, that is, the rear end of the seat 100.

[0129] Specifically, the pivot seat 430 includes a through-connection portion 433 formed on both sides of the first engaging groove 431, and the first connecting hole 432 mentioned above has two and is respectively arranged on the two through-connection portions 433. In the first embodiment, a bracket 120 is formed on the seat portion 100. The bracket 120 includes a bracket body 121, a bracket bottom wall 122 and two bracket side walls 123. The bracket body 121 is connected to the bracket bottom wall 122 at an angle, and the two bracket side walls 123 are connected to both sides of the bracket body 121 and the bracket bottom wall 122 and are arranged opposite to each other. The pivot member 420 is connected between the two bracket side walls 123. The through-connection hole 130 is defined between the pivot member 420, the bracket body 121, the bracket bottom wall 122 and the two bracket side walls 123. The through-connection portion 433 is suitable for being accommodated in the through-connection hole 130 to form a connection between the backrest portion 200 and the seat portion 100.

[0130] See also Figure 8 and Fig.10 In the first embodiment, the infant carrier is provided with two sets of the above-mentioned pivot structures 400, and the two sets of the pivot structures 400 are arranged at intervals along the left-right direction of the infant carrier. In this way, the stability of the backrest portion 200 pivoting relative to the seat portion 100 can be improved. Of course, one or more sets of the above-mentioned pivot structures 400 can also be provided as needed, and the present invention is not limited thereto.

[0131] See also Figures 11 to 14The adjusting mechanism 500 is arranged between the seat portion 100 and the backrest portion 200, and is used to adjust the angle between the seat portion 100 and the backrest portion 200 and to keep the angle between the two unchanged. Specifically, the adjusting mechanism 500 includes a locking member 510, a locking member 520 and a first operating member 530. The locking member 510 is installed on one of the seat portion 100 and the backrest portion 200, and a locking recess 511 is provided on the locking member 510. In the first embodiment, the locking member 520 is a locking pin. The locking member 520 is installed on the other of the seat portion 100 and the backrest portion 200. The locking member 520 can engage and disengage with the locking recess 511 to lock and release the backrest portion 200 and the seat portion 100. In the first embodiment, the moving direction of the locking member 520 is perpendicular to the transverse width direction of the seat portion 100 or the backrest portion 200. The locking member 520 moves in a direction perpendicular to the transverse width direction of the seat portion 100 or the backrest portion 200 to lock and release the seat portion 100 and the backrest portion 200, so that the setting of the moving stroke and path of the locking member 520 can be more flexible. Specifically, the locking member 510 is a sheet-like structure and the plane where the locking member 510 is located is perpendicular to the transverse width direction of the seat portion 100 or the backrest portion 200, and the locking recess 511 and the sliding recess 512 are both provided on the sheet-like locking member, so the plane where the locking recess 511 and the sliding recess 512 are located is also perpendicular to the transverse width direction of the seat portion 100 or the backrest portion 200.

[0132] The first operating member 530 is movably mounted on the other of the seat portion 100 and the backrest portion 200, and has a locking position and an unlocking position on its moving path. The first operating member 530 is operably connected to the locking member 520 to drive the locking member 520 to move on the locking member 510. Specifically, when the first operating member 530 is in the locking position, the locking member 520 is located in the locking recess 511, and the backrest portion 200 is fixed relative to the seat portion 100, which is equivalent to the backrest portion 200 cannot rotate relative to the seat portion 100, thereby allowing the infant carrier to remain in a specific use state, such as in the first use state or the second use state. When the first operating member 530 is in the unlocking position, the locking member 520 retreats from the locking recess 511, and the backrest portion 200 can pivot relative to the seat portion 100, which is equivalent to adjusting the angle between the backrest portion 200 and the seat portion 100. At the same time, the locking member 510 is arranged on the seat portion 100 to effectively strengthen the strength of the adjustment mechanism 500. Since the adjustment mechanism 500 of the backrest portion 200 and the seat portion 100 is subjected to greater force when a collision occurs, strengthening the strength of the adjustment mechanism 500 by the locking member 510 can help prevent the baby carrier from being deformed when it is hit. In the first embodiment, the locking member 510 is mounted on the seat portion 100, but the locking member 510 can also be integrally formed on the seat portion 100, as long as it plays a role in strengthening the structural strength there. In addition, the locking member 510 is arranged at the upper edge of the seat portion 100 or the backrest portion 200 to be as far away from the pivot structure 400 as possible; such an arrangement disperses the force points of the entire baby carrier, makes the force more uniform, avoids stress concentration, and ensures the impact performance of the baby carrier when it is hit.

[0133] The structure and working principle of the above-mentioned adjustment mechanism 500 are relatively simple. It only needs to control the position of the first operating member 530 to make the locking member 520 enter or withdraw from the locking recess 511, and then the angle between the seat part 100 and the backrest part 200 can be adjusted. This process is convenient to operate and is not prone to jamming, which can effectively improve the stability of angle adjustment.

[0134] See also Figures 13 to 15 In some examples, the locking recess 511 includes at least two locking grooves 5111. The locking member 510 is further provided with a sliding recess 512, which is connected to each locking groove 5111, and the groove wall of the sliding recess 512 and the groove wall of each locking groove 5111 form a closed structure. The locking member 520 is movably disposed in the sliding recess 512 and each locking groove 5111. When the first operating member 530 is in the locking position (see Fig.11 and Fig.13), at this time, the locking member 520 is located in one of the locking grooves 5111, and the backrest portion 200 is fixed relative to the seat portion 100. When the locking member 520 is located in each of the locking grooves 5111, the angle between the backrest portion 200 and the seat portion 100 is different, which is equivalent to the baby carrier presenting different backrest angle states accordingly. When the first operating member 530 is in the unlocked position (see Fig.14 ), at this time, the locking member 520 is located in the sliding recess 512, and the backrest portion 200 can pivot relative to the seat portion 100.

[0135] Specifically, in the first embodiment, if Fig.15 As shown, one of the locking grooves 5111 is referred to as the first locking groove 5111A, and the other locking groove 5111 is referred to as the second locking groove 5111B. The sliding recess 512 is connected to the first locking groove 5111A and the second locking groove 5111B. In this way, it is considered that the locking member 520 is movably inserted into the sliding recess 512, the first locking groove 5111A, and the second locking groove 5111B. Specifically, when the first operating member 530 is in the locked position, the locking member 520 can be located in the first locking groove 5111A or the second locking groove 5111B. More specifically, when the locking member 520 is located in the first locking groove 5111A, the seat portion 100 and the backrest portion 200 are at a first angle, and the baby carrier 1000 is in a first use state. When the locking member 520 is located in the second locking groove 5111B, the seat portion 100 and the backrest portion 200 are at a second angle, the first angle is greater than the second angle, and the baby carrier 1000 is in the second use state. Fig.11 and Fig.13 As shown, when the locking member 520 is located in the first locking groove 5111A, the infant carrier is in the first usage state, at this time, the angle between the backrest portion 200 and the seat portion 100 is called the first angle; when the locking member 520 is located in the second locking groove 5111B, the infant carrier is in the first usage state, at this time, the angle between the backrest portion 200 and the seat portion 100 is called the second angle; wherein the first angle is greater than the second angle.

[0136] See also Figures 13 to 15In some examples, when the number of locking grooves 5111 is greater than three, the locking grooves 5111 other than the first locking groove A and the second locking groove B can be regarded as transition grooves 5111C. Such transition grooves 5111C are located between the first locking groove 5111A and the second locking groove 5111B and are in communication with the sliding recess 512. For example, in the first embodiment, there are three locking grooves 5111, including the first locking groove 5111A, the second locking groove 5111B and the transition groove 5111C, and the transition groove 5111C is located between the first locking groove 5111A and the second locking groove 5111B. In other embodiments, there can also be four locking grooves 5111, including the first locking groove 5111A, the second locking groove 5111B and the two transition grooves 5111C. The two transition grooves 5111C are both located between the first locking groove 5111A and the second locking groove 5111B. When the locking member 520 is located in such a transition groove 5111C, the seat portion 100 and the backrest portion 200 are at a third angle, which is greater than the second angle and less than the first angle. The infant carrier is in a transition state between the first use state and the second use state, that is, when the infant carrier is in the transition state, the angle between the backrest portion 200 and the seat portion 100 is between the first angle and the second angle. Specifically, the more transition grooves 5111C there are, the smaller the adjustment interval of the angle between the backrest portion 200 and the seat portion 100, and the user can more accurately adjust the angle between the backrest portion 200 and the seat portion 100, so that the state of the infant carrier is more in line with the riding needs of infants and young children, and the comfort is higher.

[0137] See also Figure 7 as well as Figures 13 to 15 , the sliding recess 512 is located above the first locking groove 5111A, the second locking groove 5111B and the transition groove 5111C, that is, the locking recess 511 is closer to the pivot structure 400 (or the rotation axis X1-X1 between the seat portion 100 and the backrest portion 200) than the sliding recess 512. When the angle between the seat portion 100 and the backrest portion 200 needs to be adjusted, the locking member 520 needs to be moved upward along the first locking groove 5111A or the second locking groove 5111B or the transition groove 5111C to the locking recess 511. When the angle between the seat portion 100 and the backrest portion 200 needs to be locked, the locking member 520 needs to be moved downward from the locking recess 511 to the first locking groove 5111A or the second locking groove 5111B or the transition groove 5111C.

[0138] In some examples, each locking groove 5111 (i.e., the first locking groove 5111A, the second locking groove 5111B, and the transition groove 5111C) is arranged at intervals in the circumferential direction around the rotation axis X1-X1 between the seat portion 100 and the backrest portion 200. It should be noted that the rotation axis X1-X1 is the rotation axis of the pivoting member 420 pivoting in the pivoting groove 410. The sliding recess 512 is an arc-shaped structure, and the arc center of the sliding recess 512 is located on the rotation axis X1-X1. In this way, when the locking member 520 withdraws from the first locking groove 5111A or the second locking groove 5111B or the transition groove 5111C to the sliding recess 512, the locking member 520 can be moved in the sliding recess 512 by rotating the backrest portion 200.

[0139] In this first embodiment, if Fig.15 As shown, since the arc of the sliding recess 512 is short, the sliding recess 512 is approximately linear. In other embodiments, the sliding recess 512 can also be set to a linear shape, as long as the sliding of the locking member 520 in the sliding recess 512 is not blocked by the locking grooves 5111A, 5111C, 5111B.

[0140] In some examples, the first operating member 530 may be directly operably connected to the locking member 520. Of course, in other alternative embodiments, the first operating member 530 may be indirectly operably connected to the locking member 520. Fig.13 and Fig.14 As shown, the adjustment mechanism 500 may further include a sliding transmission member 540, and the first operating member 530 is operably connected to the locking member 520 through the sliding transmission member 540. Specifically, the sliding transmission member 540 is provided with a connecting portion 541 and a transmission portion 542. The locking member 520 is disposed on the connecting portion 541, and a guide groove 543 is provided on the transmission portion 542. The guide groove 543 extends obliquely relative to the moving direction (first direction F1) of the first operating member 530. More specifically, in the first embodiment, as shown in FIG. Figures 11 to 14As shown, the locking member 510 is mounted on the seat portion 100. The first operating member 530 is movably mounted on the backrest portion 200 and has a driving member 531. The driving member 531 can slide in the guide groove 543 to drive the sliding transmission member 540 to drive the locking member 520 to move relative to the locking member 510 along the second direction F2, so that the locking member 520 switches between the sliding recess 512 and the locking recess 511. It should be noted that in the first embodiment, the moving direction of the first operating member 530 (i.e., the first direction F1) is the same as the extending direction of the backrest portion 200 along the front-back direction, and the first direction F1 is perpendicular to the horizontal width direction of the seat portion 100 or the backrest portion 200. The moving directions of the sliding transmission member 540 and the locking member 520 (i.e., the second direction F2) are perpendicular to both the first direction F1 and the horizontal width direction of the seat portion 100 or the backrest portion 200. The locking member 520 in the existing baby carrier is mostly moved in the lateral width direction of the seat portion 100 or the backrest portion 200 to lock and release the seat portion 100 and the backrest portion 200, while the locking member 520 in the first embodiment is moved in a direction perpendicular to the lateral width direction of the seat portion 100 or the backrest portion 200 to lock and release the seat portion 100 and the backrest portion 200, so that the setting of the moving stroke and path of the locking member 520 can be more flexible.

[0141] See also Fig.11 and Fig.16 In some examples, the driving part 531 includes a latch 5311 and a pulling block 5312. The pulling block 5312 is in a U-shaped structure and has a first clamping cavity 5313. The first clamping cavity 5313 is used to clamp the transmission part 542 of the sliding transmission member 540. The latch 5311 passes through a side wall of the first clamping cavity 5313 and the guide groove 543 in sequence and then connects with the other side wall of the first clamping cavity 5313. In this way, the latch 5311 is not easy to be separated from the guide groove 543 when sliding in the guide groove 543, thereby improving the stability of the driving connection between the first operating member 530 and the sliding transmission member 540.

[0142] See also Figure 2 , Fig.13 as well as Fig.14 In some examples, the first operating member 530 further includes an operating portion 532. The operating portion 532 is located at a side of the backrest portion 200 away from the seating space 300 and at a rear end of the backrest portion 200. The operating portion 532 is exposed through the operating hole 201 of the backrest portion 200 so as to be operated and connected to the driving portion 531. In this way, the user can directly control the first operating member 530 to switch between the locked position and the unlocked position through the operating portion 532, thereby controlling the sliding of the driving portion 531 in the guide groove 543.

[0143] See also Fig.13 , Fig.14 as well as Fig.17In some examples, the guide groove 543 has a first groove end 5431 and a second groove end 5432 that are arranged opposite to each other. Specifically, the first groove end 5431 is closer to the locking member 510 than the second groove end 5432, and along the moving direction (first direction F1) of the first operating member 530, the second groove end 5432 is closer to the operating portion 532 than the first groove end 5431. More specifically, when the first operating member 530 is in the locked position (see Fig.13 ), the driving portion 531 is located at the first slot end 5431. When the first operating member 530 is in the unlocking position (see Fig.14 ), the driving portion 531 is located at the second slot end 5432. Specifically, when the user pulls the operating part 532 to make the driving part 531 move from the first groove end 5431 to the second groove end 5432, the driving part 531 can drive the sliding transmission member 540 to move upward relative to the locking member 510 along the guiding direction of the locking groove 5111 (the first locking groove 5111A or the second locking groove 5111B or the transition groove 5111C), and then drive the locking member 520 to move from the locking groove 5111 to the sliding recess 512. In this way, the locking member 520 is not restricted by the locking groove 5111, so that the locking member 520 can move in the sliding recess 512 along the circumferential direction of the rotation axis X1-X1. Therefore, when the first operating member 530 is in the unlocked position, that is, when the locking member 520 moves to the sliding recess 512, the user can adjust the state of the infant carrier by pushing the backrest 200 to rotate the backrest 200 around the rotation axis X1-X1.

[0144] See also Fig.11 In some examples, when the locking member 510 is mounted on the inner wall of the seat portion 100, a gap is left between it and the inner wall. The connecting portion 541 of the sliding transmission member 540 is in a U-shaped structure and has a second clamping cavity 544. The second clamping cavity 544 is used to clamp the locking member 510. The locking member 520 passes through one side wall of the second clamping cavity 544, the locking recess 511 or the sliding recess 512 of the locking member 510 in sequence, and then connects with the other side wall of the second clamping cavity 544. In this way, the locking member 520 can be prevented from being separated from the locking recess 511 or the sliding recess 512 during the movement, thereby improving the stability of the angle adjustment of the infant carrier.

[0145] In this first embodiment, if Fig.11 and Fig.12 As shown, the locking member 520 is connected to the connecting portion 541 of the sliding transmission member 540 through the latch 570. Specifically, the locking member 520 passes through the through hole 5441 on the side wall of the second holding cavity 544 (see Fig.17) and then connected to the latch 570, the size of the latch 570 (specifically the length L1) is larger than the diameter of the through hole 5441, so that the latch 570 can abut against the edge of the through hole 5441 to prevent the locking member 520 from detaching from the connecting portion 541 from the through hole 5441.

[0146] See also Fig.11 and Fig.12 In some examples, the adjustment mechanism 500 may further include a mounting frame 550. Optionally, the mounting frame 550 is fixedly mounted on the backrest portion 200, or the mounting frame 550 is detachably mounted on the backrest portion 200. Fig.12 and Fig.18 As shown, the mounting frame 550 is provided with a strip-shaped slide groove 551, and the strip-shaped slide groove 551 extends from the locking recess 511 to the sliding recess 512. Fig.12 and Fig.13 As shown, the locking member 520 passes through the strip-shaped slide groove 551 and the connecting portion 541 and is movably inserted into the sliding recess 512 or the locking recess 511. Further, the size of the latch 570 (specifically, the length L1) is greater than the width L2 of the strip-shaped slide groove 551, so that the locking member 520 can be prevented from being separated from the strip-shaped slide groove 551 during the movement. When the locking member 520 moves to the sliding recess 512, the user pushes the backrest portion 200 to make the mounting frame 500 rotate with the backrest portion 200 around the rotation axis X1-X1. At the same time, the mounting frame 500 will push the locking member 520 to rotate around the rotation axis X1-X1 in the locking recess 511, thereby changing the angle between the backrest portion 200 and the seat portion 100.

[0147] See you again Fig.11 and Fig.12 In some examples, the adjustment mechanism 500 may further include a reset member 560. The reset member 560 abuts between the mounting bracket 550 and the sliding transmission member 540. The reset member 560 is used to drive the sliding transmission member 540 to reset so that the locking member 520 moves from the sliding recess 512 to the locking recess 511 (the first locking groove 5111A or the second locking groove 5111B or the transition groove 5111C). Specifically, the reset member 560 may be a spring or other types of elastic members. In the first embodiment, the reset member 560 is a spring. Fig.17 As shown, a third holding cavity 545 is formed on the sliding transmission member 540. Fig.12 and Fig.13 As shown, the spring is accommodated in the third holding cavity 545, one end of the spring abuts against the bottom wall of the third holding cavity 545, and the other end abuts against the mounting frame 550, so that the spring can be prevented from deflecting during compression or resetting. More specifically, there is a limiting convex column 546 in the third holding cavity 545, and the spring is sleeved on the limiting convex column 546, so that the spring can be further prevented from deflecting.

[0148] Combine the following Figure 6 , Figure 7 as well as Figure 12 to Figure 14 The working process of adjusting the state of the infant carrier (the angle between the backrest portion 200 and the seat portion 100) is described below.

[0149] like Fig.13 As shown, when the locking member 520 is located in the first locking groove 5111A, the groove wall of the first locking groove 5111A can limit the locking member 520 from moving into other locking grooves 5111, thereby limiting the backrest portion 200 from pivoting relative to the seat portion 100, thereby allowing the infant carrier to remain in a lying state.

[0150] like Fig.14 As shown, when the user needs to adjust the state of the infant carrier, that is, when the infant carrier needs to be switched from the lying state to the transition state or to the sitting state, the user can pull the operating part 532 upward along the first direction F1, so that the operating part 532 drives the driving part 531 to move upward along the first direction F1. When the operating part 532 moves upward along the first direction F1, under the action of the guide groove 543, the driving part 531 can drive the sliding transmission member 540 and the locking member 520 to move upward along the second direction F2 relative to the locking member 510, thereby causing the locking member 520 to withdraw from the first locking groove 5111A to the sliding recess 512, and at the same time, the reset member 560 is compressed. When the locking member 520 moves into the sliding recess 512, it can push the backrest portion 200, so that the backrest portion 200 rotates relative to the seat portion 100 around the rotation axis X1-X1. At the same time, the mounting frame 550 pushes the locking member 520 to move around the rotation axis X1-X1 in the sliding recess 512 while rotating with the backrest portion 200. When the locking member 520 moves to the top of the transition groove 5111C or the second locking groove 5111B, the user can release the operating part 532. At this time, the reset member 560 is reset, and the reset member 560 pushes the sliding transmission member 540 to move downward in the opposite direction of the second direction F2, so that the locking member 520 can enter the transition groove 5111C or the second locking groove 5111B from the sliding recess 512. Specifically, when the sliding transmission member 540 moves downward in the opposite direction of the second direction F2, the guide groove 543 can move the driving portion 531 downward in the opposite direction of the first direction F1, thereby resetting the operating portion 532 and placing the first operating member 530 in the locked position.

[0151] In some examples, there may be one or more adjustment mechanisms 500. Specifically, in the first embodiment, there are two adjustment mechanisms 500, and the two adjustment mechanisms 500 are arranged at intervals along the left and right directions of the infant carrier. In some examples, the first operating members 530 in each adjustment mechanism 500 are arranged in parallel, and the operating parts 532 of each first operating member 530 are independent of each other. When it is necessary to adjust the state of the infant carrier, the two operating parts 532 can be operated at the same time. In the first embodiment, Fig.16 As shown, each first operating member 530 shares one operating portion 532, which means that the driving portion 531 of each first operating member 530 is controlled by the same operating portion 532. In this way, the two driving portions 531 can be controlled simultaneously through the operating portion 532, thereby simultaneously controlling the two sliding transmission members 540 and the two locking members 520.

[0152] The baby carrier and the adjustment mechanism 500 thereof according to the first embodiment of the utility model have at least the following technical effects:

[0153] The adjustment mechanism 500 is arranged between the seat portion 100 and the backrest portion 200 for adjusting the angle between the two, wherein the locking member 510 is mounted on the seat portion 100 or the backrest portion 200, and the first operating member 530 is movably mounted on the backrest portion 200 or the seat portion 100. Since the locking member 520 is movably arranged on the locking member 510 and the first operating member 530 is operably connected to the locking member 520, the position of the locking member 520 on the locking member 510 can be directly controlled by controlling the first operating member 530. Specifically, since the first operating member 530 has a locking position and an unlocking position on its moving path, when the first operating member 530 is in the locking position, the locking member 520 is limited in the locking recess 511 on the locking member 510, so that the backrest 200 can be fixed relative to the seat 100, so that the angle between the two remains unchanged; and when the first operating member 530 moves to the unlocking position, the first operating member 530 has driven the locking member 520 to withdraw from the locking recess 511, so that the backrest 200 can be pivoted relative to the seat 100 to adjust the angle between the two. The structure and working principle of the above-mentioned adjustment mechanism 500 are relatively simple. Only by controlling the position of the first operating member 530, the locking member 520 can enter or withdraw from the locking recess 511, and then the angle between the seat 100 and the backrest 200 can be adjusted. The process is convenient to operate and is not prone to jamming, which can effectively improve the stability of angle adjustment.

[0154] like Figures 19 to 21As shown, the second embodiment of the present invention provides a baby carrier 1000. Similar to the baby carrier of the first embodiment, the baby carrier of the second embodiment of the present invention also includes a seat portion 100 and a backrest portion 200. Different from the first embodiment, in the baby carrier of the second embodiment, the backrest portion 200 and the seat portion 100 are pivotally connected at a fixed first pivot point 101, and the baby carrier of the second embodiment also includes an adjustment mechanism arranged between the backrest portion 200 and the seat portion 100, so that the backrest portion 200 can switch between at least two angular positions relative to the seat portion 100. In this second embodiment, in order to distinguish it from the first embodiment, the adjustment mechanism is referred to as an adjustment device 600. In other words, the adjustment device 600 is a modified example of the adjustment mechanism 500.

[0155] Specifically, the seat portion 100 may include a shell 110 and a leg rest portion 150. The backrest portion 200 and the shell 110 may be pivotally connected to form a seating space 300 for carrying infants. In the second embodiment, the leg rest portion 150 and the shell 110 are an integrally formed structure.

[0156] The backrest 200 has at least two angular positions relative to the housing 110 to accommodate different sitting requirements of infants and young children. Fig.19 The first angle position of the backrest portion 200 and the housing 110 is suitable for the sitting posture of infants and young children. Fig. 20 The third angle position of the backrest portion 200 and the housing 110 is suitable for a reclining position of an infant. Fig.21 The second angle position of the backrest 200 and the shell 110 is suitable for the lying posture of the infant, etc. It should be understood that the angle positions of the backrest 200 and the shell 110 can also be set to more than three or less than three as needed, and the present invention is not limited to this. In addition, it should be understood that the correspondence between the first angle position, the second angle position, and the third angle position of the backrest 200 and the shell 110 and the posture of the infant on the baby carrier 1000 is only exemplary, and does not necessarily correspond to the sitting posture of the infant, the lying posture of the infant, and the reclining posture of the infant, respectively. For example, the first angle position can also be suitable for the lying posture of the infant, the second angle position can also be suitable for the reclining posture of the infant, and the third angle position can also be suitable for the sitting posture of the infant, etc., and the present invention is not limited to this.

[0157] like Figure 22 to Figure 24As shown, the housing 110 is provided with a handle combination 102, which is used to combine with the handle 7000 of the baby carrier 1000. The direction that the infant faces when riding in the baby carrier 1000 is the front, and the direction from the bottom edge of the housing 110 to the handle combination 102 is the top. The first pivot point 101 is located in front of the handle combination 102, which is beneficial to the collision force performance of the baby carrier 1000. Furthermore, the first pivot point 101 is located near the bottom, which is beneficial to lowering the center of gravity of the infant riding in the baby carrier 1000 and improving the safety of the infant riding. Figures 19 to 24 The subsequent figures still use arrow "F" to indicate the front, arrow "B" to indicate the back, arrow "U" to indicate the top, and arrow "D" to indicate the bottom. The direction indicated by arrow "F" is the direction that the infant faces when sitting in the infant carrier 1000.

[0158] Fig.25 and Fig.26 FIG. 1 is a schematic diagram of the three-dimensional structure of the baby carrier 1000 in this embodiment. Fig.25 The first angular position of the backrest 200 and the housing 110 of the baby carrier 1000 is suitable for a sitting position of an infant. Fig.26 The second angle position of the backrest 200 and the housing 110 of the baby carrier 1000 is suitable for a lying position of an infant. Fig. 27 The backrest portion 200 includes a backrest body 210, backrest side panels 220 connected to both sides of the backrest body 210, and a backrest extension portion 230 connected to the lower side of the backrest body 210. When the backrest portion 200 is pivotally connected to the shell 110, the backrest extension portion 230 is located on the side of the shell 110 facing the seating space. A headrest portion 280 for supporting the head of an infant is provided on the side of the backrest body 210 away from the backrest extension portion 230. The headrest portion 280 is slidably connected to the backrest body 210, so that the position of the headrest portion 280 relative to the backrest body 210 can be adjusted according to the body shape of the infant. Please refer to Fig.28 The shell 110 is an integrally formed structure, generally including a shell body 112 and shell side plates 113 connected to both sides of the shell body 112. The leg support portion 150 is fixed to a side of the shell body 112 away from the back support extension portion 230, and is used to support the legs of infants and young children. In this embodiment, the leg support portion 150 and the shell body 112 are an integrally formed structure.

[0159] like Fig.29 As shown, the two backrest side plates 220 of the backrest portion 200 are pivotally connected to the two shell side plates 113 of the shell 110 respectively. Fig.30 for Fig.29The enlarged view at point A shows the specific pivot structure of one of the back-rest side plates 220 and the corresponding shell side plate 113. At least the lower end of the back-rest side plate 220 is located on the inner side of the corresponding shell side plate 113. A pivot hole 221 is provided at the lower end of the back-rest side plate 220, and a pivot protrusion 1210 is provided on the inner side of the shell side plate 113. The pivot protrusion 1210 is provided with a pivot groove (not shown in the drawings), and a pivot shaft (not shown in the drawings) passes through the pivot hole 221 and the pivot groove on the pivot protrusion 1210 to realize the pivot connection between the back-rest side plate 220 and the corresponding shell side plate 113. In other embodiments, the positions of the pivot hole 221 and the pivot protrusion 1210 can also be interchanged. Alternatively, the back-rest side plate 220 and the corresponding shell side plate 113 can also be pivoted through other structures.

[0160] like Fig.31 As shown, the adjustment device 600 includes a locking mechanism 610 and an operating mechanism 620 .

[0161] The locking mechanism 610 is disposed between the shell 110 and the backrest portion 200, and the locking mechanism 610 has a locking state that fixes the backrest portion 200 at one of at least two angular positions (such as the first angular position or the second angular position) and a releasing state that allows the backrest portion 200 to switch between at least two angular positions (such as the first angular position and the second angular position).

[0162] In this embodiment, Fig.31 As shown, the backrest side panels 220 and the shell side panels 113 on both sides of the infant carrier 1000 are provided with locking mechanisms 610 to achieve smooth adjustment of the angular position of the backrest portion 200 . Fig.32 for Fig.31 The enlarged view of the B position shows the specific structure of the locking mechanism 610 on one side. The upper edge of the housing 110 facing the passenger space is provided with the following mounting portion 710, and the mounting portion 710 is provided with at least two engagement grooves 711. The at least two engagement grooves 711 include a third engagement groove 711 and a fourth engagement groove 711. The arrangement direction of the at least two engagement grooves 711 is staggered with the front-to-back direction. Figure 32 to Figure 35, the locking mechanism 610 includes an actuator 611 and a locking pin 612. The actuator 611 includes an actuator body 6111 and a positioning protrusion 6112 protruding from one side of the actuator body 6111. In this embodiment, the actuator 611 is an integrally formed structure. In other embodiments, the actuator 611 can also be connected by welding or riveting the actuator body 6111 and the positioning protrusion 6112. The actuator body 6111 is roughly a rectangular parallelepiped structure, and the actuator body 6111 has a first side 6111a, a second side 6111b and a third side 6111c. The first side 6111a, the second side 6111b and the third side 6111c are adjacent to each other. The first side 6111a of the actuator body 6111 is provided with a mounting hole 6111d, and one end of the locking pin 612 is inserted into the mounting hole 6111d. The second side 6111b of the actuator body 6111 is provided with a substantially rectangular mounting groove 6111e, and the mounting groove 6111e is connected to the mounting hole 6111d. In the present embodiment, the mounting groove 6111e is a rectangular groove, and a side groove wall of the rectangular groove is connected with an elastic finger 6111f. One of the locking pin 612 and the elastic finger 6111f is provided with a protrusion (not shown in the accompanying drawings), and the other is provided with a recess (not shown in the accompanying drawings). When the locking pin 612 is inserted into the mounting hole 6111d, the protrusion and the recess are inserted and matched, and the locking pin 612 is pressed and fixed in the mounting hole 6111d by the elastic force of the elastic finger 6111f. In the present embodiment, the elastic finger 6111f is provided with a protrusion, and the locking pin 612 is provided with a recess. The positioning protrusion 6112 is convexly provided on the third side 6111c of the actuator body 6111. The extending direction of the mounting hole 6111d is intersected with the extending direction of the positioning protrusion 6112. The portion of the locking pin 612 located outside the mounting hole 6111d forms a locking portion 6122. The locking portion 6122 can be engaged with one of the at least two engagement grooves 711 (such as the third engagement groove 711 or the fourth engagement groove 711) to fix the backrest 200 at a certain angular position (such as the first angular position or the second angular position).

[0163] Furthermore, the mounting portion 710 is located behind the handle combination portion 102. In combination with the above, the first pivot point 101 is located at the front lower side of the handle combination portion 102, that is, the first pivot point 101 and the mounting portion 710 are respectively located on both sides of the handle combination portion 102. In this way, a better force-bearing structure is formed, which is conducive to dispersing the impact force on the baby carrier 1000 when the vehicle collides, making the baby carrier 1000 less likely to be damaged.

[0164] like Fig.33 and Fig.34 As shown, the operating mechanism 620 includes a second operating member 621 , a traction member 622 , a linkage member 623 and an operation reset member 624 .

[0165] In this embodiment, the second operating member 621 is a handle, which is operably disposed on a side of the backrest body 210 away from the backrest extension portion 230 .

[0166] There are two linkage members 623, which are respectively connected to the actuators 611 of the locking mechanism 610 on both sides. There are two traction members 622, and both ends of each traction member 622 are respectively connected to the second operating member 621 and the linkage member 623 on the corresponding side. Both linkage members 623 are movably arranged on the side of the backrest 200 facing away from the seating space. The linkage member 623 includes a mounting bracket 6231 and a linkage part 6232 connected to each other.

[0167] The mounting bracket 6231 is generally in a rectangular frame structure and extends along the longitudinal direction of the backrest portion 200. One end of the mounting bracket 6231 is connected to the traction member 622, and the other end is connected to the linkage portion 6232. An accommodating space 6231a is formed in the mounting bracket 6231, and the operating reset member 624 is accommodated in the accommodating space 6231a. In this embodiment, the operating reset member 624 is a spring. One end of the operating reset member 624 is connected or abutted to the linkage member 623, and the other end of the operating reset member 624 is connected or abutted to the stopper 240 on the backrest portion 200. The operating reset member 624 is suitable for enabling the linkage member 623 to drive the second operating member 621 to reset. In one embodiment, the stopper 240 is also arranged in the accommodating space 6231a. A mounting base 6231b is provided on one side of the mounting bracket 6231 close to the linkage portion 6232 (or close to the locking mechanism 610), one end of the operating reset member 624 is fixed to the mounting base 6231b, and the other end is fixed to the stopper 240. Further, a guide member 241 is also provided on the mounting bracket 6231 or the stopper 240, and the operating reset member 624 is sleeved on the guide member 241 to prevent the operating reset member 624 from shifting during the biasing process. The mounting bracket 6231 includes a first side portion 6231d and a second side portion 6231e that are arranged opposite to each other, and a stopper 6231c is connected to the substantially middle portion of the first side portion 6231d and the substantially middle portion of the second side portion 6231e to prevent the operating reset member 624 from escaping from the accommodating space 6231a.

[0168] like Fig.34As shown, the linkage part 6232 is also roughly rectangular in structure, and the extension direction of the linkage part 6232 is staggered with the extension direction of the mounting bracket 6231, for example, the extension direction of the linkage part 6232 and the extension direction of the mounting bracket 6231 can be set at a 45-degree angle. The linkage part 6232 is provided with a slide groove 6233 extending along its extension direction. In other embodiments, the extension direction of the linkage part 6232 may not be staggered with the extension direction of the mounting bracket 6231, as long as the setting direction of the slide groove 6233 is staggered with the extension direction of the mounting bracket 6231. The positioning protrusion 6112 of the actuator 611 forms a first sliding fit portion, and the slide groove 6233 of the linkage part 623 forms a second sliding fit portion. The positioning protrusion 6112 is inserted into the slide groove 6233 and can move along the slide groove 6233, thereby realizing the sliding fit of the actuator 611 and the linkage part 623.

[0169] Furthermore, combined with Fig.32 and Fig.34 The locking portion 6122 can move in a direction close to or away from the mounting portion 710, that is, it can move in a direction close to or away from a certain engagement groove 711 (such as the third engagement groove 711 or the fourth engagement groove 711). The setting direction of the slide groove 6233 is inclined to the moving direction of the locking portion 6122. Specifically, the slide groove 6233 is inclined upward along the direction close to the mounting portion 710, that is, in this embodiment, the slide groove 6233 is inclined upward along the direction from the inside to the outside.

[0170] Specifically, the backrest body 210 includes a backrest board 211 and a cover body 212 that is arranged on a side of the backrest board 211 that faces away from the seating space. The backrest board 211 and the cover body enclose an installation space. The actuating member 611 and at least part of the locking pin 612 in the locking mechanism 610, and the traction member 622 and the linkage member 623 in the operating mechanism 620 are all installed in the installation space, thereby making the appearance of the baby carrier more neat and tidy, and protecting the relevant parts of the locking mechanism 610 and the operating mechanism 620 from being easily damaged.

[0171] When the second operating member 621 is pulled, the second operating member 621 can pull the linkage member 623 through the traction member 622 to move in the direction close to the second operating member 621, that is, pull the linkage member 623 to move upward, and the linkage member 623 drives the actuator 611 to drive the locking pin 612 to move in the direction away from the mounting portion 710 through the sliding fit between the slide groove 6233 and the positioning protrusion 6112, that is, move in the direction away from the corresponding engagement groove 711 (such as the third engagement groove 711), until the locking portion 6122 of the locking pin 612 disengages from the corresponding engagement groove 711 (such as the third engagement groove 711), and the locking mechanism 610 is in a released state. At this time, the backrest portion 200 can be rotated relative to the housing 110. When the backrest portion 200 is rotated relative to the housing 110 to a desired angular position, the locking portion 6122 is opposite to another engagement groove 711 (such as the fourth engagement groove 711), and the force pulling the second operating member 621 can be removed. At this time, the linkage member 623 can move away from the second operating member 621 under the elastic force of the operating reset member 624, that is, move downward, so that the locking pin 612 moves toward the mounting portion 710 or another engagement groove 711 (such as the fourth engagement groove 711) until the locking portion 6122 of the locking pin 612 is inserted into another engagement groove 711 (such as the fourth engagement groove 711). In this way, the backrest portion 200 can achieve the adjustment of the angular position.

[0172] In one example, if Figure 36 to Figure 38 As shown, the infant carrier 1000 further includes a mounting plate 700 of a generally rectangular plate-like structure, the mounting plate 700 being fixedly connected to the housing 110, and a mounting portion 710 and a limiting rib 720 are respectively provided on both sides of the mounting plate 700. The mounting portion 710 and the limiting rib 720 both protrude toward the seating space. In this embodiment, the mounting plate 700 has two inner sides of two shell side plates 113 respectively fixedly connected to the housing 110. The edges of the two back-resting side plates 220 close to the back-resting extension portion 230, i.e., the lower edges of the two back-resting side plates 220, form a stop surface 222. The backrest portion 200 can be pivoted relative to the housing 110 until the stop surface 222 abuts against the limiting rib 720 to limit the pivoting angle between the backrest portion 200 and the housing 110. In this embodiment, when the backrest portion 200 is pivoted relative to the housing 110 to a sitting position suitable for infants and young children, the stop surface 222 abuts against the limiting rib 720. In this way, it is possible to prevent the backrest portion 200 from excessively pivoting relative to the shell 110, thereby preventing the backrest portion 200 from causing safety hazards or uncomfortable riding experience to the infant or young child riding there.

[0173] Furthermore, if Fig.32 As shown, the mounting portion 710 protrudes toward the backrest portion 200 , and the backrest portion 200 is provided with an avoidance recess 250 corresponding to the mounting portion 710 to allow the backrest portion 200 to pivot relative to the housing 110 .

[0174] Furthermore, if Figure 26 to Figure 28 As shown, the backrest extension 230 is provided with a sliding hole 231, and the portion of the shell body 112 relatively far from the leg rest portion 150, that is, the portion of the shell body 112 overlapping with the backrest extension 230 is provided with a connecting hole 111, one of the sliding hole 231 and the connecting hole 111 is a bar-shaped hole, and the sliding hole 231 and the connecting hole 111 at least partially overlap, and a sliding pin (not shown in the drawings) passes through the sliding hole 231 and the connecting hole 111 to guide the backrest 200 to move in the front-to-back direction relative to the shell body 110. When the backrest 200 rotates relative to the shell body 110, the backrest extension 230 or the backrest 200 is driven to move relative to the shell body 112 along the front-to-back direction of the infant carrier 1000, and the movement of the backrest extension 230 or the backrest 200 can be guided by the cooperation of the sliding pin, the sliding hole 231 and the connecting hole 111.

[0175] According to the second embodiment of the baby carrier 1000 of the present invention, the purpose of adjusting to suit the sitting posture of the infant can be achieved by simply rotating the backrest portion 200, without involving the linkage between other components (such as the backrest portion and the legrest portion), and the adjustment is convenient and the structure is simple.

[0176] In addition, it should be understood that the backrest assembly 200 shown in the second embodiment can also be applied to the baby carrier of the first embodiment. Accordingly, a sliding hole 231 is provided on the backrest extension 230, and a connecting hole is also provided on the portion of the shell 110 corresponding to the backrest extension. A sliding pin (not shown in the drawings) passes through the sliding hole 231 and the connecting hole to guide the backrest 200 to move in the front-to-back direction relative to the shell 110. When the backrest 200 rotates relative to the shell 110, the backrest extension 230 or the backrest 200 is driven to move relative to the shell 110 along the front-to-back direction of the baby carrier 1000, and the movement of the backrest extension 230 or the backrest 200 can be guided by the cooperation of the sliding pin, the sliding hole 231 and the connecting hole.

[0177] like Fig.39 and Fig.40As shown, the structure of the baby carrier 1000 proposed in the third embodiment of the utility model is substantially the same as that of the second embodiment, except that the backrest 200 and the legrest 150 of the baby carrier 1000 are connected to the front and rear sides of the shell 110, and the legrest 150 is fixedly connected to the shell 110. In this embodiment, the legrest 150 is fixedly connected to the shell 110 by fasteners such as screws. The backrest 200 and the shell 110 are pivotally connected at a fixed first pivot point 101. One of the backrest 200 and the shell 110 can also be provided with a limiting protrusion 260, and the other is provided with a limiting groove 1300, and the limiting protrusion 260 is inserted in the limiting groove 1300. When the backrest 200 pivots relative to the shell 110, the limiting protrusion 260 slides in the limiting groove 1300, thereby guiding the rotation stroke of the backrest 200, so that the rotation is more stable. Specifically, the limiting groove 1300 is provided in the arc groove of the rear edge of the shell side plate, and the arc groove has a first end 131 and a second end 132. When the pivot angle between the backrest portion 200 and the shell 110 is the smallest, that is, the infant carrier 1000 is suitable for the sitting state of the infant, the limiting protrusion 260 moves to the first end 131 of the limiting groove 1300, as shown in FIG. Fig.39 When the pivot angle between the backrest portion 200 and the housing 110 is at a maximum, that is, the infant carrier 1000 is suitable for the infant to sit or lie flat, the limiting protrusion 260 moves to the second end 132 of the limiting groove 1300, as shown in FIG. Fig.40 In this embodiment, the first end 131 is located above and in front of the second end 132. The two backrest side plates 220 of the backrest portion 200 are both provided with limiting protrusions 260, and the two shell side plates 113 of the shell 110 are correspondingly provided with limiting grooves 1300 that can slide with the two limiting protrusions 260 respectively.

[0178] The position of the first pivot point 101 between the backrest portion 200 and the shell 110 and the setting position of the engagement groove 711 in this embodiment are similar to those in the second embodiment. In this embodiment, the first pivot point 101 is located at the front lower side of the handle combination portion 102, and the mounting portion 710 is arranged behind the handle combination portion 102 and at the upper edge of the side of the shell 110 facing the seating space. Specifically, the first pivot point 101 is located at the middle lower position of the shell side plate 113. The limiting protrusion 260 and the limiting groove 1300 are arranged at the rear of the shell 110. In this embodiment, the two shell side plates 113 are provided with a matching hole 1220 located at the first pivot point 101, and the two backrest side plates 220 are correspondingly provided with a pivot pin 223 that can be inserted and matched with the pivot hole 221, so as to realize the pivot connection between the shell side plate 113 (or the shell 110) and the backrest side plate 220 (or the backrest portion 200). In this embodiment, the position of the pivot point 101 is relatively fixed, that is, the pivot pin 223 can only pivot but cannot move up and down or forward and backward.

[0179] like Fig.41 and Fig.42 As shown, the structure of the baby carrier 1000 proposed in the fourth embodiment of the present invention is substantially the same as that of the third embodiment, except that the backrest 200 and the legrest 150 are pivotally connected to the third pivot point 104 through a pin, and the legrest 150 and the housing 110 are pivotally connected to the second pivot point 103. The legrest 150 can rotate relative to the housing 110 around the second pivot point 103. Specifically, one of the legrest 150 and the housing 110 can be provided with a rotation pin (not shown in the drawings), and the other can be provided with a rotation hole (not shown in the drawings), and the legrest 150 and the housing 110 are pivotally connected to the second pivot point 103 through the insertion and matching of the rotation pin and the rotation hole. The pin at the third pivot point 104 can slide along the height direction of the housing 110. Specifically, the front sides of the two housing side plates 113 are provided with matching holes 1220, and the matching holes 1220 are arranged along the height direction of the housing 110. The rear sides of the two backrest side plates 220 are respectively pivotally connected with the legrest portion 150 at two pivot pins 223. Each pivot pin 223 is inserted into the corresponding matching hole 1220 and can move along the matching hole 1220. In this way, when the legrest portion 150 rotates relative to the housing 110, the legrest portion 150 will drive the backrest portion 200 pivotally connected thereto to flip backward, and the pivot pin 223 will slide in the matching hole 1220 along the height direction of the housing 110. The position of the third pivot point 104 of the backrest portion 200 and the legrest portion 150 and the setting position of the mounting portion 710 in this embodiment are similar to those in the second embodiment. In this embodiment, the third pivot point 104 is located at the front lower side of the handle combination portion 102, and the mounting portion 710 is arranged behind the handle combination portion 102 and at the upper edge of the side of the housing 110 facing the seating space.

[0180] Furthermore, the backrest portion 200 can move relative to the housing 110. Specifically, a moving protrusion 270 can be provided on one of the backrest portion 200 and the housing 110, and a moving long slot 140 can be provided on the other, and the moving protrusion 270 is inserted into the moving long slot 140 and can move along the moving long slot 140. When the leg rest portion 150 rotates relative to the housing 110 and the third pivot point 104 between the leg rest portion 150 and the backrest portion 200 moves in the height direction, the backrest portion 200 will move in the front-rear direction relative to the housing 110, and the setting of the moving protrusion 270 and the moving long slot 140 can guide the relative movement of the backrest portion 200 and the housing 110.

[0181] The above-mentioned adjustment device and baby carrier have at least the following technical effects:

[0182] The adjusting device 600 of the above-mentioned baby carrier selectively limits the angular position of the backrest portion 200 relative to the housing 110 through the locking mechanism 610 disposed between the housing 110 and the backrest portion 200, and drives the locking mechanism 610 to switch from a locked state to a released state through the operating mechanism 620. In this way, the user only needs to operate the operating mechanism 620 to adjust the angular position of the backrest portion 200 without performing other operations, which is convenient to use. Moreover, the angular position of the backrest portion 200 relative to the housing 110 can be adjusted to different sitting postures of infants and young children, without involving linkage between other components, and the structure is simple and easy to implement.

[0183] It is understandable that the linkage arrangement of the backrest assembly and the shell of the second to fourth embodiments of the utility model can be applied to the first embodiment, and the pivot structure of the first embodiment of the utility model can also be applied to the second to fourth embodiments, and the utility model will not repeat them.
