[0059] In order to explain the technical content and structural features of the present invention in detail, the following is a further description in conjunction with the embodiments and the accompanying drawings.

[0060] See also Figures 1 to 6 and Figures 16 to 18 The present invention provides a child carrier 100, comprising a carrier body 101 and a seat belt adjustment structure 10 disposed on the carrier body 101. The seat belt adjustment structure 10 is suitable for adjusting the position of the seat belt of the child carrier 100. The carrier body 101 may be a baby stroller, a baby carrier, or a car seat. The seat belt adjustment structure 10 allows the position of the seat belt on the baby stroller, baby carrier, or car seat to be adjusted. Specifically, the seat belt adjustment structure 10 includes a support member 11 that is movable on the child carrier 100 and is provided with multiple rows of adjustment portions 12 at different heights for restraining the seat belt. The position of the seat belt is adjusted by the movement of the support member 11 on the child carrier 100 and the engagement of the seat belt with the adjustment portions 12 at different heights. An opening 16 may also be provided on the side of the support member 11, connecting to at least two rows of adjustment portions 12. The opening 16 allows the seat belt to engage with the adjustment portions 12 at different heights to adjust the position of the seat belt relative to the child's shoulder.

[0061] By adopting the above technical solution, the child carrier 100 of the present invention is equipped with a seat belt adjustment structure 10 on the carrier body 101, which allows the seat belt to be adjusted relative to the child's shoulders on the carrier body 101. The child carrier 100 of the present invention can accommodate children of various sizes and body shapes, and the seat belt is easily adjustable, providing a more comfortable fit. The seat belt adjustment structure 10 of the present invention includes a support member 11 that is movably mounted on the child carrier 100. The support member 11 is provided with multiple rows of adjustment sections 12 at different heights, and the seat belt can be adapted to fit the different adjustment sections 12. Specifically, the movement of the support member 11 allows the position of the seat belt to be adjusted to better suit the user. The position of the seat belt can also be adjusted by adapting the seat belt to different users. Of course, the position of the support member 11 on the carrier body 101 can also be adjusted simultaneously with the position of the different adjustment sections 12 on the support member 11, allowing the seat belt to be more adapted to children of different sizes and body shapes. The seat belt adjustment structure 10 of the present invention can adjust the position of the seat belt to adapt it to different users. The seat belt adjustment structure 10 of the present invention not only adjusts the position of the seat belt via the support member 11, but also adjusts the position of the seat belt via different adjustment portions 12 on the support member 11 in conjunction with the seat belt. It has a simple structure, is easy to operate, and offers greater adaptability.

[0062] See also Figures 1 to 8 In some optional embodiments, the vehicle body 101 is provided with a backrest 40 and a headrest 20 that is adjustable on the backrest 40. The seatbelt adjustment structure 10 can be linked to the headrest 20. When the headrest 20 is raised or lowered, the seatbelt adjustment structure 10 rises and falls with the headrest 20. For example, the support member 11 can be connected to the headrest 20, or the seatbelt adjustment structure 10 can be directly mounted on the headrest 20. Alternatively, the support member 11 and the headrest 20 can be integrally formed. In some embodiments, the support member 11 can be movable relative to the headrest 20. The specific structure and connection method of the support member 11 and the headrest 20 can be customized according to actual needs. Since the seatbelt adjustment structure 10 is linked to the headrest 20, when the headrest 20 is raised or lowered, the seatbelt adjustment structure 10 rises and falls synchronously with the headrest 20. This allows the seatbelt adjustment structure 10 and the headrest 20 to be adjusted to the appropriate position simultaneously to accommodate children of different body shapes. The safety belt can also be matched with different adjustment parts 12 according to the size of the child so that the position of the safety belt is more suitable for the user and the child can be more comfortable to use.

[0063] See also Figures 1 to 8In some optional embodiments, a first belt pass-through 211 is provided on the inner panel 21 of the headrest 20. When an older child uses the child carrier 100 of the present invention, the vehicle seat belt can be passed through the first belt pass-through 211 to provide protection for the child. On the other hand, when a younger child uses the child carrier 100 of the present invention, the first belt pass-through 211 allows for more convenient adjustment of the headrest 20, thereby more conveniently adjusting the support member 11 through the headrest 20 to position the belt within the support member 11 within an appropriate range based on the user's size and body shape. Furthermore, the coordination of the belt with the various adjustment sections 12 provides for more comfortable use. In this embodiment, a second belt pass-through 42 is provided on the backrest 40. When the belt adjustment structure 10 on the carrier body 101 is used, the vehicle seat belt can be passed through the second belt pass-through 42 to secure the child carrier 100 to the car seat, providing a safer fit. The entire carrier body 101 can also be moved more conveniently through the second seat belt passer 42. It is understandable that the safety belt of the vehicle seat will pass through the first seat belt passer 211 or the second seat belt passer 42 when it is engaged with the child carrier 100. With the help of the first seat belt passer 211 and the second seat belt passer 42, the safety belt of the vehicle seat will provide reliable protection for the child riding in the child carrier 100 without affecting the child's riding comfort. The provision of the first seat belt passer 211 and the second seat belt passer 42 can also effectively reduce the weight of the carrier body 101, making the whole body lighter and saving materials. The child carrier 100 of the present invention can be flexibly applied to children of various sizes and is comfortable to use.

[0064] See also Figure 8 and Figure 13 In some optional embodiments, the headrest 20 includes an inner plate 21 and an outer cover 22. The inner plate 21 can be connected to the support member 11, or the inner plate 21 and the support member 11 are an integral structure. The outer cover 22 is detachably mounted on the inner plate 21, and the appearance of the outer cover 22 matches the inner plate 21. The outer cover 22 has a flexible structure, which makes it more comfortable for the user to use when leaning on the headrest 20. The outer cover 22 is detachable and more convenient to clean. It can be understood that when the outer cover 22 is mounted on the inner plate 21, the adjustment part 12 on the support member 11 is located outside the outer cover 22, so that the adjustment part 12 can better cooperate with the safety belt, and the safety belt can be better adjusted between multiple adjustment parts 12. The structure is simple and the design is reasonable.

[0065] See also Figure 7 、 Figure 14 and Figure 15In some optional embodiments, the child carrier 100 is further provided with a lifting and adjusting structure 30 that cooperates with the support member 11. The support member 11 is provided with a locking member 14 that cooperates with the lifting and adjusting structure 30. The locking member 14 engages with different positions of the lifting and adjusting structure 30 to position the support member 11 at different positions on the child carrier 100. The locking member 14 can be provided on the support member 11, or when the seat belt adjustment structure 10 is provided on the headrest 20, the locking member 14 can also be provided on the headrest 20. The locking member 14 is located on the surface of the support member 11 or the headrest 20 that mates with the backrest 40. The lifting and adjusting structure 30 is located on the backrest 40. Through the cooperation of the locking member 14 and the lifting and adjusting structure 30, the headrest 20 and the support member 11 can be positioned at different positions on the backrest 40, thereby adapting the child carrier to different users. Specifically, the lifting and adjusting structure 30 is provided with a plurality of engaging holes 31 that can cooperate with the engaging member 14. The engaging member 14 engages with different engaging holes 31 to adjust the position of the support member 11. The engaging member 14 is movably disposed on the back of the headrest 20 or the support member 11 via the fixing member 15. The engaging member 14 engages with different engaging holes 31 to adjust the position of the headrest 20 and the support member 11 on the backrest 40. When the engaging member 14 moves out of the engaging hole 31, the headrest 20 and the support member 11 are released and can slide relative to the backrest 40 to adjust their positions relative to the backrest 40. When the headrest 20 and the support member 11 are slid and adjusted to the appropriate position, the engaging member 14 engages with the corresponding engaging hole 31, locking the headrest 20 and the support member 11 to the backrest 40. This simple structure and convenient adjustment are achieved.

[0066] See also Figure 6 In some optional embodiments, the carrier body 101 is provided with a mounting hole 41 for inserting and installing a seat belt, and the seat belt engages with the various adjustment portions 12 within the mounting hole 41. It will be appreciated that the seat belt is secured to the carrier body 101 and passes through the mounting hole 41 on the backrest 40 so that the seat belt can pass through the mounting hole 41 and engage with the adjustment portion 12 on the support member 11.

[0067] See also Figures 1 to 12 In some optional embodiments, the adjustment portion 12 is in the form of a through-slot structure 120 through which a horizontal safety belt can move. It is understandable that a safety belt is generally long and flat, and the adjustment portion 12 is in the form of a through-slot structure 120 so that the safety belt in a horizontal state can move through the through-slot structure 120. The through-slot structure 120 can be in the form of a long strip so as to match the safety belt in a horizontal state. Specifically, the length of the through-slot structure 120 is longer than the width of the safety belt, and the width of the through-slot structure 120 is wider than the thickness of the safety belt, so that the safety belt can move through the through-slot structure 120 smoothly, and the safety belt will not overlap when passing through the through-slot structure 120, making it more comfortable to use.

[0068] See also Figures 1 to 12 In some optional embodiments, the through-slot structures 120 of two adjacent rows of corresponding adjustment portions 12 are interconnected. Specifically, the through-slot structures 120 of two adjacent rows of corresponding adjustment portions 12 are interconnected via a vertical slot structure 13 through which the vertical safety belt slides. It is understood that the safety belt can slide from one through-slot structure 120 to another through-slot structure 120 via the vertical slot structure 13. Without removing the safety belt, the safety belt can slide from one through-slot structure 120 to another, making it easier to adjust the position of the safety belt. On the other hand, the vertical slot structure 13 only allows the vertical safety belt to slide through, preventing the safety belt from sliding from one through-slot structure 120 to another freely, making the safety belt more securely positioned within the through-slot structure 120. The connection between the through-slot structure 120 and the vertical slot structure 13 is an arc-shaped portion 121. The specific shape of each arc portion 121 can be set according to the actual transition situation. The arc-shaped transition between the through-groove structure 120 and the vertical groove structure 13 allows for smoother sliding of the safety belt, reduces friction between the through-groove structure 120 and the vertical groove structure 13, and extends the lifespan of the safety belt. For example, the vertical groove structure 13 can be a vertical strip-shaped structure, or it can be an arc-shaped structure, as long as the vertical groove structure 13 is capable of accommodating the vertical safety belt. Alternatively, the vertical groove structure 13 can be semicircular. The middle section of the semicircular vertical groove structure 13 provides a larger accommodation space, which can effectively organize the safety belt sliding within the vertical groove structure 13. The semicircular vertical groove structure 13 can be used to adjust a twisted safety belt, making the use of the safety belt more comfortable. Of course, the vertical groove structure 13 can also have other structures with a larger accommodation space in the middle section, as long as the accommodation space can be used to adjust the safety belt. The minimum width of the vertical groove structure 13 is greater than the thickness of the safety belt, so that the safety belt can slide smoothly within the vertical groove structure 13.

[0069] See also Figures 8 to 12 and Figure 17 and Figure 18 In some optional embodiments, a first limiting portion 122 may be provided between the through-groove structure 120 and the vertical groove structure 13 or the opening portion 16, and the first limiting portion 122 is used to limit the sliding of the safety belt in the through-groove structure 120. A second limiting portion 123 may also be provided between the through-groove structure 120 and the first limiting portion 122, and the second limiting portion 123 is used to limit the sliding of the safety belt in the through-groove structure 120. The height of the first limiting portion 122 and / or the second limiting portion 123 protruding in the adjustment portion 12 is higher than the thickness of the safety belt, so that the safety belt can be placed more firmly in the adjustment portion 12 and will not slide out of the adjustment portion 12 at will. In one embodiment, as Figure 9As shown, a first limiting portion 122 with a curved structure can be provided between part of the through-groove structure 120 and the vertical groove structure 13. The first limiting portion 122 protrudes from the bottom of the through-groove structure 120 to prevent the safety belt from sliding freely in the through-groove structure 120, making the structure more stable. That is, the first limiting portion 122 can be provided in part between the through-groove structure 120 and the vertical groove structure 13, while not provided in part. In another embodiment, as shown in FIG. Figure 10 As shown, a first limiting portion 122 is provided between all the through-slot structures 120 and the vertical slot structures 13, so that the safety belt will not slide freely in the through-slot structure 120, and the structure is more stable. Figure 12 As shown, a second limiting portion 123 may be provided between the through-slot structure 120 and the first limiting portion 122. The second limiting portion 123 may reinforce the parking of the safety belt in the through-slot structure 120, so that the safety belt can be more firmly parked in the through-slot structure 120 and the structure is more stable. In another embodiment, as Figure 17 As shown, a first limiting portion 122 may be provided between the through-slot structure 120 and the opening 16, and a second limiting portion 123 may also be provided between the first limiting portion 122 and the through-slot structure 120. Figure 18 As shown, a vertical slot structure 13 may be provided between the through slot structure 120 and the opening 16, and a first limiting portion 122 may be provided between the through slot structure 120 and the vertical slot structure 13, and a second limiting portion 123 may also be provided between the first limiting portion 122 and the through slot structure 120. It is understood that each adjustment portion 12 may be directly connected to the vertical slot structure 13 or the opening 16. A first limiting portion 122 may also be provided between each adjustment portion 12 and the vertical slot structure 13 or the opening 16 to limit the movement of the safety belt within the adjustment portion 12. A first limiting portion 122 and a second limiting portion 123 may also be provided between each adjustment portion 12 and the vertical slot structure 13 to allow the safety belt to be more securely positioned within the adjustment portion 12. The shape of the second limiting portion 123 may be set according to actual usage requirements. For example, the second limiting portion 123 may have a wavy structure, and the specific number of convex and concave portions in the wavy structure is not specifically limited.

[0070] See also Figure 16 and Figure 18In some optional embodiments, an opening 16 is provided on the side of the support member 11. The opening 16 connects to at least two adjacent slot structures 120, facilitating the transition of the safety belt between different adjustment sections 12. It is understood that the opening 16 can be directly provided on the side of the support member 11 and connected to multiple adjustment sections 12 on the same side. The adjustment sections 12 in the same row generally include two adjustment sections 12 for accommodating left and right shoulder straps, and the two adjustment sections 12 in the same row are not connected. The two adjustment sections 12 in the same row are connected to different openings 16 on the left and right sides, respectively. The opening 16 allows for easier transition of the safety belt between different adjustment sections 12 on the same side, making operation more convenient. Furthermore, providing the opening 16 on the support member 11 simplifies the molding process, saves material, and makes the support member 11 lighter overall, effectively reducing costs. The opening 16 also allows for easier placement and removal of the safety belt from the adjustment section 12. In other embodiments, two adjacent rows of corresponding adjustment portions 12 can be connected to each other through a vertical groove structure 13, and an opening portion 16 connected to the vertical groove structure 13 is opened on the side of the support member 11 (such as Figure 18 As shown). That is, a vertical slot structure 13 for the vertical safety belt to slide is further provided between the opening portion 16 and the through-slot structure 120. After the state of the safety belt is adjusted, the safety belt can enter the through-slot structure 120 more smoothly by providing the vertical slot structure 13, so as to prevent the safety belt from being twisted or wrinkled during the sliding process. The opening portion 16 is connected to at least two adjacent through-slot structures 120 through the vertical slot structure 13. The adjustment portions 12 located on the same side can be connected to each other through the vertical slot structure 13, and the vertical slot structure 13 is provided with an opening portion 16, so that the safety belt can be more conveniently switched between different adjustment portions 12. The provision of the opening portion 16 can well adjust the twisted safety belt, making the operation more convenient.

[0071] See also Figure 17 and Figure 18 In some optional embodiments, a guide portion 161 is provided between the opening portion 16 and the adjusting portion 12. The guide portion 161 is in a gradual structure that gradually narrows along the direction in which the opening portion 16 enters the adjusting portion 12. In the case where a vertical groove structure 13 is provided, the guide portion 161 is provided between the vertical groove structure 13 and the opening portion 16. It can be understood that the guide portion 161 has a larger opening at one end close to the opening portion 16, so that the safety belt can more conveniently enter the vertical groove structure 13 or the adjusting portion 12. The connection between the guide portion 161 and the opening portion 16 is in an arc shape, and the arc transition between the opening portion 16 and the guide portion 161 can avoid scratching the safety belt. Please refer to Figure 4 and Figure 5In some optional embodiments, the safety belt adjustment structure 10 is provided on the headrest 20, and the safety belt adjustment structure 10 rises and falls with the rise and fall of the headrest 20 so as to be better suitable for different users. In this embodiment, the adjustment portion 12 in a through groove structure 120 is arranged on the support member 11 in a structure of two rows and two columns. The adjustment portion 12 is provided with two columns to allow two safety belts to pass through, and the adjustment portion 12 is provided with two rows at different heights so that the safety belt can be suitable for children of different ages and different usage needs. Exemplarily, the child carrier 100 is a car safety seat, and when the headrest 20 is in a lower position (such as Figure 4 The child carrier 100 is suitable for smaller children. The angle of the child carrier 100 can be adjusted so that the smaller child can sleep in the child carrier 100.
