[0068] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0069] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values ​​set forth in these embodiments do not limit the scope of the present disclosure. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to actual proportional relationships. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0070] In the related art, the adjustment mechanism used in the child safety seat with adjustable seat tilt angle needs to withstand the pressure from the seat and provide guidance for the relative movement between the seat and the base. If the material of the adjustment mechanism is too small, it will not be able to complete the above functions. Therefore, the adjustment mechanism is usually heavy and costly, which is not conducive to the lightweighting of the child safety seat.

[0071] FIG1 is a schematic structural diagram of some embodiments of a child safety seat according to the present disclosure. Referring to FIG1 , the child safety seat includes a seat body 1 , a base assembly 2 , and a bracket assembly 3 .

[0072] Base assembly 2 includes, but is not limited to, an arcuate shape to conform to the curved bottom of seat body 1, thereby supporting the bottom of seat body 1. Bracket assembly 3 is located between base assembly 2 and seat body 1 and is removably connected to base assembly 2; bracket assembly 3 includes, but is not limited to, being positioned near the bottom of seat body 1. Seat body 1 is movably connected to bracket assembly 3 and is configured to adjust its tilt angle relative to base assembly 2 under the guidance of bracket assembly 3.

[0073] The force of the seat body 1 is transmitted to the base assembly 2 through the bracket assembly 3. Since the bracket assembly 3 does not need to bear the supporting force, the bracket assembly 3 can be made of lighter materials such as plastic, thereby reducing the weight of the child safety seat and making it easier for users to carry.

[0074] In this embodiment, by providing a support assembly 3 connected to the base assembly 2 and movably connected to the seat body 1, the user can adjust the tilt angle of the seat body 1 relative to the support assembly 3 and the base assembly 2 by operating the seat body 1, thereby adjusting the tilt posture of the seat body 1 to meet the user's diverse usage needs. The support assembly 3 is arranged between the base assembly 2 and the seat body 1, and the seat body 1 is supported by the base assembly 2 rather than the support assembly 3. The support assembly 3 does not need to be subjected to force, which allows the support assembly 3 to be made of lighter materials, thereby achieving a lightweight child safety seat. In addition, because the support assembly 3 avoids the situation where local force affects the smoothness of angle adjustment, it also makes the tilt angle adjustment of the seat body 1 more convenient and flexible, and the support assembly 3 has higher reliability.

[0075] FIG2 is a schematic diagram of the structure of a bracket assembly according to some embodiments of the child safety seat disclosed herein. FIG3A is a schematic diagram of the structure of a seat body according to some embodiments of the child safety seat disclosed herein. Referring to FIG1 to FIG3A , in some embodiments, a slide groove group 11 is provided on both sides of the bottom of the seat body 1. The slide groove group 11 includes, but is not limited to, a position near the bottom of the seat body 1. The length of the slide groove group 11 corresponds to the range of adjustment of the tilt angle of the seat body 1 relative to the base assembly 2.

[0076] The bracket assembly 3 includes a bracket body 31 and a sliding rod 32, which is mounted on the bracket body 31. The two ends of the sliding rod 32 slide within the guide grooves 11 on either side of the seat body 1, respectively, to facilitate sliding engagement between the seat body 1 and the bracket assembly 3. The user can manipulate the seat body 1 to adjust the position of the sliding rod 32 within the guide grooves 11. Different positions of the sliding rod 32 within the guide grooves 11 correspond to different tilt angles of the seat body 1 relative to the base assembly 2.

[0077] In this embodiment, the sliding cooperation between the sliding rod 32 and the sliding groove assembly 11 can realize flexible adjustment of the tilting posture of the seat body 1 relative to the base assembly 2, and the tilting angle adjustment process is more stable.
