In order to facilitate the adjustment of the normal state and the lying position, as shown in FIG. 2, the adjusting component 3 includes a push-pull element 6, which is connected with the first slider 1 and is movable in a direction away from the first slider 1. The push-pull element 6 is arranged on the housing 4. The design of the push-pull element 6 is convenient for moving the first slider 1 through the push-pull element 6, thereby changing the included angle between the first slider 1 and the second slider 2, and realizing the adjustment of the normal state and the lying position. The push-pull element 6 is arranged on the housing 4 and outside the housing 4, which is convenient for users to use and does not affect the sitting and lying of children inside.

[0052] Specifically, the outer surface of the housing 4 is provided with a guide groove 16, and part of the push-pull member 6 is arranged on the guide groove 16, so that the moving direction of the push-pull member 6 is guided by the guide groove 16, and the reliable movement of the push-pull member 6 is ensured. In order to facilitate the adjustment between the normal state and the lying position, it also includes a limit block 7, and the limit block 7 is used to limit the maximum extension range of the first slider 1. The limit block 7 is arranged on the first slider 1, and the housing 4 is provided with a limit groove 8 matched with the limit block 7. The opening of the limit groove 8 faces away from the push-pull element 6, and the limit block 7 is arranged on the limit groove 8. The design of the limit block 7 limits the maximum outward movement distance of the push-pull element 6, which is convenient for controlling the deformation from the normal state to the lying position. The limit groove 8 and the limit block 7 are matched, so that the movement of the first slider 1 is limited by the limit groove 8, and the opening direction of the limit groove 8 is far away from the push-pull element 6, so that the push-pull element 6 pushes outward, so that the limit block 7 moves towards the bottom of the limit groove 8, and finally abuts against the bottom of the limit groove 8 to reach a limited position.

[0053] In order to improve the support of lying position, as shown in FIG. 3, the housing 4 is provided with a raised support block 9, which is arranged below the first slider 1 or the second slider 2, and the bottom surface of the first slider 1 or the bottom surface of the second slider 2 abuts against the support block 9 when the first slider 1 and the second slider 2 are unfolded. The design of the support block 9 enables the first slider 1 or the second slider 2 to be supported, ensuring the support reliability in normal state or lying position.

[0054] In this embodiment, the support block 9 is arranged below the first slider 1, and the housing 4 includes a bracket 17. The bottom surface of the first slider 1 is provided with a downward protruding abutment block 18, and the support block 9 is arranged on the bracket 17.

[0055] When in use, it only needs to pull the push-pull element 6, and the push-pull element 6 will drive the first slider 1 to extend outwards, so that the included angle between the first slider 1 and the second slider 2 is increased, and the normal state of the seat can be adjusted to the lying position.

[0056] Embodiment 2:

[0057] As shown in FIG. 4 to FIG. 6, a lying position adjusting structure of a carrier provided by this embodiment includes: [0058] a first slider 1 used for the upper body of a child to lean against; [0059] a second slider 2 used for the lower body of the child to lean against; [0060] an adjusting component 3 used for adjusting the included angle between the first slider 1 and the second slider 2; [0061] a housing 4 for providing installation positions.

[0062] The first slider 1, the second slider 2 and the adjusting component 3 are all arranged on the housing 4. One end of the second slider 2 is hinged with the housing 4, and the other end of the second slider 2 is hinged with the first slider 1 through the rotating shaft 5. Part of the adjusting component 3 is arranged between the first slider 1 and the housing 4 or between the second slider 2 and the housing 4. In order to facilitate the adjustment of normal state and lying position, the adjusting component 3 includes a safety belt 10, and the housing 4 includes two side guard plates 11. One side guard plate 11 is provided with a fixing point 12, and the other side guard plate 11 is provided with an adjusting button 13. One end of the safety belt 10 is connected with the fixing point 12, and part of the safety belt 10 passes under the first slider 1 or the second slider 2 and passes through the adjusting button 13. The design of the guard plate 11 can protect both sides. The design of the safety belt 10 can not only fix children, but also adjust the included angle between the first slider 1 and the second slider 2, and also support under the first slider 1 or the second slider 2. The fixing point 12 is used to fix the safety belt 10 to prevent the safety belt 10 from moving, and the adjusting button 13 is used to control the tightness of the safety belt 10. Part of the safety belt 10 is under the first slider 1 or the second slider 2, which is convenient for pulling up the first slider 1 or the second slider 2 after the safety belt 10 is tightened, so as to adjust the included angle between the first slider 1 and the second slider 2. The adjusting button 13 is a commonly used structure on the safety belt 10, and will not be described in detail in this application.

[0063] For more reliable support, a part of the first slider 1 and a part of the second slider 2 overlap, and part of the safety belt 10 is arranged between the first slider 1 and the second slider 2. Part of the first slider 1 and part of the second slider 2 overlap, so that the strength of the main stressed part is strengthened. The safety belt 10 is arranged between the first slider 1 and the second slider 2, so that when the safety belt 10 is pulled up, only the first slider 1 or the second slider 2 is pulled, which can prevent the first slider 1 and the second slider 2 from colliding or crashing. Moreover, the safety belt 10 has a small space in the middle and is not easy to fold.

[0064] In order to ensure the safety belt 10 to be set reliably, as shown in FIGS. 7 to 9, the adjusting component 3 further includes guide sheets 14, which are arranged on both sides of the first slider 1. The guide sheets 14 are sleeved on the rotating shaft 5, and are provided with openings 15 matched with the safety belt 10, and the openings 15 are arranged above the rotating shaft 5. The design of the guide sheet 14 can make the passing of the safety belt 10 be reliable. The guide sheets 14 are arranged on both sides of the first slider 1, so that the safety belt 10 can be straight between the two guide sheets 14, and the effect of pulling the first slider 1 or the second slider 2 is good. The guide sheet 14 is sleeved on the rotating shaft 5, which can ensure that the guide sheet 14 moves with the rotating shaft 5, so that the safety belt 10 moves with the rotating shaft 5, thus ensuring the arrangement of the safety belt 10.

[0065] In order to set the safety belt 10 reliably, the first slider 1 is set above the second slider 2, and part of the upper surface of the safety belt 10 abuts against the bottom surface of the first slider 1. The upper surface of the safety belt 10 abuts against the bottom surface of the first slider 1, so that the safety belt 10 can always be attached to the bottom surface of the first slider 1, and the safety belt 10 can be prevented from being folded.
