[0035] Please refer to Figure 1 to Figure 4 An embodiment of the utility model provides a ceiling assembly 100, which includes a support assembly 10 and a cover 20. The cover 20 is arranged on the support assembly 10. The support assembly 10 can be switched between an unfolded state and a folded state. The cover 20 can be opened with the unfolding of the support assembly 10, and can also be folded and retracted with the support assembly 10. The support assembly 10 includes a first bottom bracket 11, a second bottom bracket 12, a first support frame 13, a second support frame 14 and a mounting seat 30. The second bottom bracket 12 is mounted on the mounting seat 30 and can rotate relative to the mounting seat 30. Figure 2 At this time, the support assembly 10 is in the unfolded state, the first bottom bracket 11 and the second bottom bracket 12 are respectively located on both sides of the bottom, and the first support frame 13 and the second support frame 14 can support the cover body 20. At this time, the first bottom bracket 11, the second bottom bracket 12 and the first support frame 13 are rotated in the same direction and close to the mounting seat 30, so that the support assembly 10 is converted from the unfolded state to the folded state. Figure 3 , at this time, the folding assembly is in the folded state. After the support assembly 10 is in the folded state, the entire support assembly 10 can be folded upward or downward by rotating the second bottom bracket 12. Figure 4 At this time, the folding assembly has been folded downward, freeing up the space above the stroller 200, so that parents can take care of the children in the seats and it is also convenient for the children to get on and off the stroller 200.

[0036] In one embodiment, the Figure 5-6The support assembly 10 further includes: a first support 15 fixed to the first bottom bracket 11, a second support 16 fixed to the second bottom bracket 12, a third support 17 fixed to the first support frame 13, and a fourth support 18 fixed to the second support frame 14. The first support 15, the third support 17 and the fourth support 18 can all rotate relative to the second support 16, thereby driving the first bottom bracket 11, the first support frame 13 and the second support frame 14 to rotate respectively.

[0037] In a preferred embodiment, in order to prevent the first bottom bracket 11 and the second bottom bracket 12 from easily rotating relative to each other, so that the folding assembly can remain stable when in the unfolded state and the folded state, the first support 15 is provided with a plurality of first positioning portions 151, and the second support 16 is provided with a plurality of second positioning portions 161. When the first positioning portions 151 are combined with the second positioning portions 161, the relative rotation between the second support 16 and the first support 15 can be limited.

[0038] In this embodiment, one of the first positioning portion 151 and the second positioning portion 161 is convex and the other is concave, and the shapes of the two are adapted and can be combined with each other. A plurality of first positioning portions 151 are distributed along the circumference of the first support 15, and a plurality of second positioning portions 161 are distributed along the circumference of the second support 16. The first positioning portion 151 and the second positioning portion 161 are combined to play a circumferential positioning role. Among them, the first positioning portion 151 and the second positioning portion 161 are preferably of a wave-shaped structure, so that the first support 15 and the second support 16 slide relative to each other, thereby promoting the combination of the first positioning portion 151 and the second positioning portion 161, and the convex parts in the first positioning portion 151 and the second positioning portion 161 are smoother and safer.

[0039] In a preferred embodiment, the support assembly 10 further includes a stopper 19 and a first spring 153. The first support 15 is provided with a receiving cavity 152. The stopper 19 includes a rod 191 extending into the receiving cavity 152 and a stopper head 192 located in the receiving cavity 152. The first spring 153 is located in the receiving cavity 152 and surrounds the outer circumference of the rod 191. When the first support 15 is separated from the second support 16 along the axial direction of the rod 191, the first support 15 compresses the first spring 153.

[0040] In this embodiment, the first positioning portion 151 of the first support 15 is disengaged from the second positioning portion 161 of the second support 16. After the rotation of the first support 15 is completed, the first spring 153 rebounds and drives the first support 15 to reset, so that the first positioning portion 151 of the first support 15 is re-combined with the second positioning portion 161 of the second support 16, thereby maintaining the current angle between the first bottom bracket 11 and the second bottom bracket 12.

[0041] In a preferred embodiment, reference may be made to Figure 2 , Figure 5 and Figure 6 When the support assembly 10 is in the unfolded state, the first support frame 13 is located between the first bottom support frame 11 and the second support frame 14. Since the first support frame 13 has a larger rotation stroke than the second support frame 14, in order to make it more stable, the third support 17 is provided with an arc-shaped limiting groove 171, and the second support 16 is provided with a limiting block 162 on the side away from the second positioning portion 161, and the limiting block 162 extends into the arc-shaped limiting groove 171.

[0042] In a preferred embodiment, in order to prevent the second bottom bracket 12 and the mounting base 30 from easily rotating relative to each other, reference may be made to Figure 7 and Figure 8 The second bottom bracket 12 is provided with a limiting rod 121, and the mounting seat 30 is provided with a sliding member 31 and a second spring 32 in contact with the sliding member 31. The sliding member 31 is provided with a receiving groove. When the limiting rod 121 is located in the receiving groove, the rotation of the second bottom bracket 12 is restricted. The user can slide the sliding member 31 to disengage the limiting rod 121 from the receiving groove, thereby being able to rotate the second bottom bracket 12. When the sliding member 31 disengages the limiting rod 121 from the receiving groove, the second spring 32 will be compressed, so that after the user lets go, the sliding member 31 will reset itself.

[0043] Preferably, the sliding member 31 is provided with a shift block 313 extending out of the shell of the mounting seat 30 so that the user can slide the sliding member 31, and the limiting rod 121 passes through the two ends of the second bottom bracket 12 along the radial direction of the second bottom bracket 12. Accordingly, the receiving grooves are designed in pairs so as to respectively accommodate the parts of the limiting rod 121 extending out of the two ends of the second bottom bracket 12.

[0044] Preferably, the receiving groove for receiving the limiting rod 121 includes a first positioning groove 311 and a second positioning groove 312, that is, the limiting rod 121 can be received in the first positioning groove 311 to play a limiting role, and can also be received in the second positioning groove 312 to play a limiting role. Among them, the depth of the first positioning groove 311 is greater than the radius of the limiting rod 121, and the depth of the second positioning groove 312 is less than the radius of the limiting rod 121.

[0045] In this embodiment, when the limiting rod 121 is located in the first positioning groove 311, the second bottom bracket 12 is approximately in a horizontal state, which will completely limit the rotation of the second bottom bracket 12 relative to the mounting seat 30, and the folding assembly will not rotate downward, thereby ensuring that the folding assembly will not rotate downward relative to the mounting seat 30, which is safer to use. When the limiting rod 121 is located in the second positioning groove 312, the second bottom bracket 12 is approximately in a vertical state, which will not completely limit the rotation of the second bottom bracket 12 relative to the mounting seat 30. The user applies a large force to rotate the second bottom bracket 12, which can make the limiting rod 121 slide out of the second positioning groove 312, thereby facilitating the second bottom bracket 12 to be converted to a horizontal state for use.

[0046] Preferably, when the limiting rod 121 is in the first positioning groove 311 , the axial direction angle thereof changes by 90° relative to when it is in the second positioning groove 312 .

[0047] In a preferred embodiment, reference may be made to Figures 9 to 11 The mounting seat 30 includes a first clamp arm 33, a second clamp arm 34 rotatably connected to the first clamp arm 33, an extrusion member 35 in contact with the second clamp arm 34, and a third spring 36 in contact with the extrusion member 35. The first clamp arm 33 and the second clamp arm 34 are preferably arc-shaped structures. The first clamp arm 33 and the second clamp arm 34 are enclosed, and the mounting seat 30 can be clamped on a rod-shaped structure, such as a push rod of a baby carriage 200. The extrusion member 35 includes a first extrusion head 351, which is located at one end of the extrusion member 35 facing the enclosed area of ​​the two clamp arms. The second clamp arm 34 includes a second extrusion head 341, which is located at one end of the second clamp arm 34 for clamping. When the second clamp arm 34 rotates in the closing direction, so that the second extrusion head 341 squeezes the first extrusion head 351 and does not pass over the first extrusion head 351, the third spring 36 is compressed.

[0048] In this embodiment, when the second clamp arm 34 rotates in the closing direction and the second extrusion head 341 passes over the first extrusion head 351, the third spring 36 drives the extrusion member 35 to return to its original position, so that the first extrusion head 351 restricts the first extrusion head 351 and the second clamp arm 34 from rotating in the opening direction. Therefore, as long as the second clamp arm 34 is fully closed, the extrusion member 35 will automatically lock the second clamp arm 34, so that the first clamp arm 33 and the second clamp arm 34 can be firmly held.

[0049] In a preferred embodiment, the mounting seat 30 further includes a pressing member 37 and a torsion spring 38, and the extrusion member 35 further includes an extrusion block 352 disposed on opposite sides of the third spring 36, the extrusion block 352 is provided with an extrusion slope 3521, and the pressing member 37 squeezes the extrusion slope 3521 to retract the extrusion member 35 and compress the third spring 36, and the torsion spring 38 is disposed on the first clamp arm 33 and enables the second clamp arm 34 to have an opening tendency.

[0050] In this embodiment, reference may be made to Fig.10 and Fig.11 The user can retract the extrusion member 35 by pressing the pressing member 37 downward, so that the second clamping arm 34 loses the limiting effect of the extrusion member 35, and the second clamping arm 34 automatically opens with the force of the torsion spring 38. When the user releases the pressing member 37, the third spring 36 rebounds to reset the extrusion member 35. Preferably, the bottom of the pressing block is provided with a lower inclined surface, which is parallel to the contact inclined surface and is used for extrusion matching with the contact inclined surface.

[0051] In one embodiment, reference may be made to Fig.12 , a baby stroller 200 is provided, the baby stroller 200 includes the ceiling assembly 100 in any of the above embodiments. The ceiling assembly 100 can be fixed on the push rod of the baby stroller 200 through the mounting seat 30. Of course, when the mounting seat 30 has a first clamping arm 33 and a second clamping arm 34, the ceiling assembly 100 can also be clamped and mounted on the push rod of the baby stroller 200.

[0052] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
