[0105] Further, as shown in Figure 6 and Figure 18 When the baby bed is used for lulling or used as a diaper table, the carrier 11 is arranged horizontally. When the baby is feeding, the carrier 11 can also be adjusted to one side to make the carrier 11 arranged at an angle with the horizontal plane, thereby preventing spitting.

[0106] When the carrier 11 is adjusted to one side, the carrier 11 is gradually inclined. In order to ensure that the connection between the carrier 11 and the supporting unit 122 does not affect the one-side adjustment of the carrier 11, in the embodiment, the carrier 11 can rotate relative to the supporting unit 122 about a preset axis extending along the first horizontal direction. The carrier 11 can move relative to the supporting unit 122 along the second horizontal direction, so that when the zipper handle 42 on one side of the carrier 11 is pulled upward, the carrier locking assembly 4 on the side will unlock the supporting unit 122, the carrier 11 can move relative to the supporting unit 122 along the second horizontal direction, the carrier 11 rotates relative to the supporting unit 122 about the preset axis, thereby adjusting the height of the one side of the carrier 11, so that the carrier 11 is arranged at an angle with the horizontal plane, and then the supporting unit 122 and the connecting unit 121 are locked through the carrier locking assembly 4 on the side.

[0107] Specifically, when the second moving part 1221c is a roller groove and the first moving part 112 is a roller, the groove width L1 of the roller groove along the second horizontal direction is greater than the width L2 of the first moving part 112 along the first direction, one end of the first moving part 112 is in rolling engagement with the second moving part 1221c along the first horizontal direction, and the other end is rotatably connected to the carrier 11 about a preset axis, and the difference between L1 and L2 is used to move the carrier 11 relative to the support unit 122 along the second horizontal direction when the carrier 11 is adjusted in height on one side, so as to meet the requirement of the inclined arrangement of the carrier 11.

[0108] In other embodiments, one end of the first moving part 112 can also be a spherical rolling element, the rolling element is in rolling engagement with the second moving part 1221c along the first horizontal direction, and the spherical rolling element is rotatable relative to the second moving part 1221c about a preset axis, and L1>L2.

[0109] In other embodiments, the carrier 11 can also be telescopic relative to the support unit 122 along the second horizontal direction, specifically, the first moving part 112 is telescopic along the second horizontal direction, the mounting end of the first moving part 112 is movable relative to the support unit 122 along the first horizontal direction, and the telescopic end of the first moving part 112 is rotatably connected to the carrier 11 about a preset axis.

[0110] In other embodiments, the part of the carrier 11 connected to the support unit 122 can be elastically deformed, so that the carrier 11 can be arranged at an angle with the horizontal plane. Specifically, the first moving part 112 is rotatably connected to the carrier 11 about a preset axis, the part of the first moving part 112 connected to the carrier 11 can be elastically deformed, the height of one side of the carrier 11 is adjusted, and the part of the first moving part 112 connected to the carrier 11 is elastically deformed, so that the carrier 11 is arranged at an angle with the horizontal plane. The part of the support unit 122 connected to the carrier 11 can also be elastically deformed, so that the carrier 11 can be arranged at an angle with the horizontal plane.

[0111] It should be noted that when the support unit 122 adopts a U-shaped structure with the opening facing upward, in order to avoid interference of the support unit 122 with the angle adjustment of the carrier 11, the second mounting part 1222 is movably connected to the two first mounting parts 1221 at the two ends thereof along the second horizontal direction, and the connection between the first mounting part 1221 and the second mounting part 1222 is the same as the connection between the carrier 11 and the support unit 122, so that the second mounting part 1222 can follow the carrier 11 to switch between the horizontal arrangement and the arrangement at an angle with the horizontal plane. In other embodiments, the second mounting part 1222 can also be omitted to avoid interference of the second mounting part 1222 with the one-side height adjustment of the carrier 11.
