DETAILED DESCRIPTION

[0037] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0038] Combination Figures 1 to 9 , according to the baby crib 100 of the embodiment of the present invention, the baby crib 100 includes a plurality of uprights and an upper enclosure group.

[0039] The crib 100 has a use space 101 and includes a plurality of vertical poles distributed around the use space 101. The crib 100 has a folded state and an unfolded state. In the folded state, the plurality of vertical poles are closed together. In the unfolded state, the plurality of vertical poles are away from each other. The plurality of vertical poles are away from each other relative to the plurality of vertical poles being closed together. When the plurality of vertical poles are closed together, the spacing between the plurality of vertical poles is small; when the plurality of vertical poles are away from each other, the spacing between the plurality of vertical poles is greater than the spacing when the plurality of vertical poles are closed together. The plurality of vertical poles include adjacent first vertical poles 10 and second vertical poles 20. The upper enclosure group is disposed between the first vertical poles 10 and second vertical poles 20. The first vertical poles 10 and second vertical poles 20 drive the upper enclosure group to be unfolded or folded, thereby realizing the unfolding and folding of the crib 100.

[0040] In addition, the crib 100 further includes an upper enclosure group, which includes: a first armrest 31, a second armrest 32, a first support rod 33, and a second support rod 34. The first end of the first armrest 31 is rotatably connected to the upper portion of the first vertical rod 10; the first end of the first support rod 33 is rotatably connected to the first vertical rod 10; the first end of the second armrest 32 is rotatably connected to the upper portion of the second vertical rod 20; the first end of the second support rod 34 is rotatably connected to the second vertical rod 20, wherein the first support rod 33 and the second support rod 34 are crossed and hinged, the second end of the first support rod 33 is rotatably connected to the second end of the second armrest 32, and the second end of the second support rod 34 is rotatably connected to the second end of the first armrest 31. The first vertical rod 10 drives the first armrest 31 to rotate, the first armrest 31 drives the second support rod 34 to rotate, the second vertical rod 20 drives the second armrest 32 to rotate, and the second armrest 32 drives the first support rod 33 to rotate, thereby realizing the folding and unfolding of the crib 100.

[0041] For example, when the crib 100 is folded, the first upright rod 10 and the second upright rod 20 are closed together, the first upright rod 10 drives the first armrest 31 to rotate upward around the first end of the first armrest 31, the second end of the first armrest 31 is linked to the second end of the second support rod 34, and drives the second support rod 34 to rotate upward around the first end of the second support rod 34; the second upright rod 20 drives the second armrest 32 to rotate upward around the first end of the second armrest 32, the second end of the second armrest 32 is linked to the second end of the first support rod 33, and drives the first support rod 33 to rotate upward around the first end of the first support rod 33, and the first support rod 33 and the second support rod 34 rotate with each other and close together. When the crib 100 is unfolded, the first vertical rod 10 and the second vertical rod 20 move away from each other, and the first vertical rod 10 drives the first armrest 31 to rotate downward around the first end of the first armrest 31, and the second end of the first armrest 31 is linked to the second end of the second support rod 34, driving the second support rod 34 to rotate downward around the first end of the second support rod 34; the second vertical rod 20 drives the second armrest 32 to rotate downward around the first end of the second armrest 32, and the second end of the second armrest 32 is linked to the second end of the first support rod 33, driving the first support rod 33 to rotate downward around the first end of the first support rod 33, and the first support rod 33 and the second support rod 34 rotate and move away from each other.

[0042] According to the baby crib 100 of the embodiment of the present invention, the baby crib 100 has a simple structure and simple steps for unfolding and folding, thereby improving the user experience.

[0043] In addition, in some embodiments of the present invention, the length of the first handrail 31 may be greater than, less than, or equal to the length of the second handrail 32, and the length of the first support rod 33 may be greater than, less than, or equal to the length of the second support rod 34. Of course, the present invention is mainly described by taking the example that the length of the first handrail 31 is equal to the length of the second handrail 32 and the length of the first support rod 33 is equal to the length of the second support rod 34, but this is not intended to limit the scope of protection of the present invention.

[0044] Combination Figure 1 In some embodiments, the first end of the first support rod 33 is located below the first end of the first armrest 31, and the first end of the second support rod 34 is located below the first end of the second armrest 32. When the crib 100 is in the unfolded state, the first support rod 33 stably supports the second armrest 32, and the second support rod 34 stably supports the first armrest 31. The first armrest 31 and the second armrest 32 have a certain force strength, which prevents the first armrest 31 and the second armrest 32 from flipping downward under force, thereby improving the stability of the structure of the crib 100 in the unfolded state.

[0045] Specifically, when the crib 100 is in the unfolded state, the first end of the first support rod 33 is connected to the first vertical rod 10, the first end of the second support rod 34 is connected to the second vertical rod 20, the first support rod 33 and the second support rod 34 are crossed and hinged, the first end of the first support rod 33, the first end of the second support rod 34 and the hinge points of the first support rod 33 and the second support rod 34 are respectively located at the three corner points of the triangle, forming a stable triangular structure, the first support rod 33 restricts the second armrest 32 from rotating downward, and the second support rod 34 restricts the first armrest 31 from continuing to rotate downward, thereby improving the reliability of the crib 100 in the unfolded state.

[0046] Optionally, the first end of the first support rod 33 can be located above the first end of the first armrest 31, and the first end of the second support rod 34 can be located above the first end of the second armrest 32. When the crib 100 is in the unfolded state, the first support rod 33 limits the rotation of the second armrest 32, and the second support rod 34 limits the rotation of the first armrest 31, which can also improve the firmness of the crib 100 in the unfolded state.

[0047] In some embodiments, the vertical poles include three, four, five or six, and different numbers of vertical poles can surround the crib 100 into different shapes. Three, four, five or six vertical poles can surround the crib 100 into a triangle, rectangle, pentagon or hexagon, respectively. Optionally, other numbers of vertical poles can be distributed around the use space 101, and the crib 100 can have different shapes, which increases the diversity of the shapes of the crib 100. Users can choose different shapes of the crib 100 according to their needs and preferences, thereby improving the user experience.

[0048] In some embodiments, in the direction surrounding the use space 101, an upper enclosure group is connected between each two adjacent vertical poles, and the two adjacent vertical poles drive the upper enclosure group when they move away from each other or close together, thereby realizing the folding and unfolding of the crib 100.

[0049] For example, two adjacent uprights include a first upright 10 and a second upright 20. When the crib 100 is folded, the first upright 10 and the second upright 20 are closed together, the first upright 10 drives the first armrest 31 to rotate upward, and the first armrest 31 drives the second support rod 34 to rotate upward; the second upright 20 drives the second armrest 32 to rotate upward, and the second armrest 32 drives the first support rod 33 to rotate upward, and the first support rod 33 and the second support rod 34 rotate relative to each other and close together; when the crib 100 is unfolded, the first upright 10 and the second upright 20 move away from each other, the first upright 10 drives the first armrest 31 to rotate downward, and the first armrest 31 drives the second support rod 34 to rotate downward; the second upright 20 drives the second armrest 32 to rotate downward, and the second armrest 32 drives the first support rod 33 to rotate downward, and the first support rod 33 and the second support rod 34 rotate relative to each other and move away from each other.

[0050] Combination Figure 4 In some embodiments, the crib 100 further includes a first connecting member 11, which fixes the first vertical rod 10, a first end of the first armrest 31 is rotatably connected to the first connecting member 11, and a second end of the first armrest 31 is rotatably connected to the second end of the second support rod 34. When the crib 100 is folded, the first vertical rod 10 drives the first armrest 31 to rotate through the first connecting member 11, and the first armrest 31 drives the second support rod 34 to rotate, thereby realizing the folding of the first armrest 31 and the second support rod 34.

[0051] Specifically, a first mounting hole is provided on the first connecting member 11, and the first connecting member 11 is fixed to the first vertical rod 10. When the baby bed 100 is folded, the first vertical rod 10 and the second vertical rod 20 are folded together, the first connecting member 11 moves with the first vertical rod 10, the first connecting member 11 drives the first armrest 31 to rotate upward around the first end of the first armrest 31, the second end of the first armrest 31 drives the second end of the second support rod 34, the first end of the second support rod 34 is rotatably connected to the second vertical rod 20, and the second support rod 34 rotates upward around the first end until the first armrest 31 and the second support rod 34 reach a folded state.

[0052] Optionally, the first connecting member 11 can be disposed at the top of the first upright 10, and the first connecting member 11 can have a first side portion and a second side portion, the first side portion can be perpendicular to the second side portion, the first side portion can extend in the left-right direction, and the second side portion can extend in the front-back direction, the first armrests 31 of the upper enclosure groups on the front and back sides of the crib 100 can be rotatably connected to the first side portion, and the second armrests 32 of the upper enclosure groups on the left and right sides of the crib 100 can be rotatably connected to the second side portion. The first connecting member 11 can be a plastic part, which has a long service life, is light in weight and has a low production cost, which is conducive to reducing the weight of the crib 100 and reducing the manufacturing cost of the crib 100.

[0053] Combination Figure 5 In some embodiments, the first connecting member 11 includes a first hinge point 111 and a first positioning portion 112. The first end of the first armrest 31 is rotatably connected to the first hinge point 111. The first positioning portion 112 is closer to the first upright pole 10 than the first hinge point 111. In the unfolded state, the first positioning portion 112 is positioned above the first armrest 31 to prevent the first armrest 31 from rotating downward. The first armrest 31 rotates around the first hinge point 111 between the unfolded state and the folded state. The first positioning portion 112 limits the first armrest 31 to prevent the first armrest 31 from flipping downward in the unfolded state, thereby ensuring the stability and firmness of the structure of the baby crib 100 in the unfolded state.

[0054] Specifically, when the crib 100 is unfolded, the first armrest 31 rotates downward around the first hinge point 111, from a folded state to an unfolded state, and the first positioning portion 112 is provided at the upper end of the first connecting member 11. When the first armrest 31 is in the unfolded state, the lower end of the first positioning portion 112 abuts against the upper end of the first armrest 31. When the first armrest 31 continues to rotate downward around the first hinge point 111, the lower end of the first positioning portion 112 restricts the first armrest 31 from continuing to rotate downward. The first armrest 31 is restricted in the unfolded state and cannot continue to rotate downward. The first positioning portion 112 realizes the positioning function of the first armrest 31.

[0055] Optionally, the first positioning portion 112 can be a rib, which can connect the gap inside the first connecting member 11, enhance the strength of the first connecting member 11, extend the service life and improve the reliability; the periphery below the rib can cooperate with the first armrest 31, and at the same time can limit the first armrest 31, restricting the first armrest 31 from rotating downward, thereby improving the reliability of the crib 100 in the unfolded state.

[0056] In some embodiments, the first connecting member 11 includes a first hinge point 111 and a second positioning portion 113. The first end of the first armrest 31 is rotatably connected to the first hinge point 111. The second positioning portion 113 is farther away from the first upright 10 than the first hinge point 111. In the unfolded state, the second positioning portion 113 is positioned below the first armrest 31 to restrict the first armrest 31 from rotating downward. The first armrest 31 rotates around the first hinge point 111 between the unfolded state and the folded state. The second positioning portion 113 limits the first armrest 31 to prevent the first armrest 31 from flipping downward in the unfolded state, thereby improving the structural stability of the crib 100 in the unfolded state.

[0057] Specifically, when the crib 100 is unfolded, the first armrest 31 rotates downward around the first hinge point 111, from a folded state to an unfolded state, and the second positioning portion 113 is provided on the side of the first hinge point 111 away from the first upright 10. When the first armrest 31 is in the unfolded state, the upper end of the second positioning portion 113 abuts against the lower end of the first armrest 31. When the first armrest 31 continues to rotate downward around the first hinge point 111, the upper end of the second positioning portion 113 restricts the first armrest 31 from continuing to rotate downward. The first armrest 31 is restricted in the unfolded state and cannot continue to rotate downward. The second positioning portion 113 realizes the positioning effect of the first armrest 31.

[0058] Optionally, the second positioning portion 113 can be a guide groove, and the two sides of the guide groove can be connected to the gap inside the first connecting member 11, so as to enhance the strength of the first connecting member 11, extend the service life and improve the reliability; the periphery above the guide groove can cooperate with the first armrest 31, and at the same time can limit the first armrest 31, restricting the first armrest 31 from rotating downward, thereby improving the reliability of the crib 100 in the unfolded state.

[0059] Combination Figure 4 In some embodiments, the crib 100 further includes a second connecting member 21, which fixes the second vertical rod 20, and the first end of the second armrest 32 is rotatably connected to the second connecting member 21, and the second end of the second armrest 32 is rotatably connected to the second end of the first support rod 33. When the first vertical rod 10 and the second vertical rod 20 are closed together, the second vertical rod 20 drives the second armrest 32 to rotate through the second connecting member 21, and the second armrest 32 drives the first support rod 33 to rotate, thereby realizing the folding of the second armrest 32 and the first support rod 33.

[0060] Specifically, a second mounting hole is provided on the second connecting member 21, and the second connecting member 21 is fixed to the second vertical rod 20. When the baby bed 100 is folded, the first vertical rod 10 and the second vertical rod 20 are folded together, the second connecting member 21 moves with the second vertical rod 20, the second connecting member 21 drives the second armrest 32 to rotate upward around the first end of the second armrest 32, the second end of the second armrest 32 drives the second end of the second support rod 34, the first end of the second support rod 34 is rotatably connected to the second vertical rod 20, and the second support rod 34 rotates upward around the first end of the second support rod 34 until the second armrest 32 and the second support rod 34 reach a folded state.

[0061] Optionally, the second connecting member 21 can be arranged at the top end of the second vertical pole 20, the second connecting member 21 can have a third side portion and a fourth side portion, the third side portion can be perpendicular to the fourth side portion, the third side portion can extend in the left-right direction, and the fourth side portion can extend in the front-back direction, the second armrests 32 of the upper enclosure groups on the front and rear sides of the crib 100 can be rotatably connected to the third side portion, and the first armrests 31 of the upper enclosure groups on the left and right sides of the crib 100 can be rotatably connected to the fourth side portion; the second connecting member 21 can be a plastic part, the plastic part has a long service life, a light weight and a low production cost, which is beneficial to reducing the weight of the crib 100 and reducing the manufacturing cost of the crib 100.

[0062] Combination Figure 6 In some embodiments, the second connecting member 21 includes a second hinge point 211 and a third positioning portion 212. The first end of the second armrest 32 is rotatably connected to the second hinge point 211. The third positioning portion 212 is closer to the second upright 20 than the second hinge point 211. In the unfolded state, the third positioning portion 212 is positioned above the second armrest 32 to prevent the second armrest 32 from rotating downward. The second armrest 32 rotates around the second hinge point 211 between the unfolded state and the folded state. The third positioning portion 212 limits the second armrest 32 to prevent the second armrest 32 from flipping downward in the unfolded state, thereby ensuring the stability and firmness of the structure of the crib 100 in the unfolded state.

[0063] Specifically, when the crib 100 is unfolded, the second armrest 32 rotates downward around the second hinge point 211, from a folded state to an unfolded state, and the third positioning portion 212 is located on the side of the second hinge point 211 close to the second upright 20, and the third positioning portion 212 is provided at the upper end of the second connecting member 21. When the second armrest 32 is in the unfolded state, the lower end of the third positioning portion 212 abuts against the upper end of the second armrest 32. When the second armrest 32 continues to rotate downward around the second hinge point 211, the lower end of the third positioning portion 212 restricts the second armrest 32 from continuing to rotate downward. The second armrest 32 is restricted in the unfolded state and cannot continue to rotate downward. The third positioning portion 212 realizes the positioning effect of the second armrest 32.

[0064] Optionally, the third positioning portion 212 can be a rib, which can connect the gap inside the second connecting member 21, enhance the strength of the second connecting member 21, extend the service life and improve reliability; the periphery below the rib can cooperate with the second armrest 32, and at the same time can limit the second armrest 32, restricting the second armrest 32 from rotating downward, thereby improving the reliability of the crib 100 in the unfolded state.

[0065] In some embodiments, the second connecting member 21 includes a second hinge point 211 and a fourth positioning portion 213. The first end of the second armrest 32 is rotatably connected to the second hinge point 211. The fourth positioning portion 213 is farther away from the second upright 20 than the second hinge point 211. In the unfolded state, the fourth positioning portion 213 is positioned below the second armrest 32 to restrict the second armrest 32 from rotating downward. The second armrest 32 rotates around the second hinge point 211 between the unfolded state and the folded state. The fourth positioning portion 213 limits the second armrest 32 to prevent the second armrest 32 from flipping downward in the unfolded state, thereby improving the structural stability of the baby crib 100 in the unfolded state.

[0066] Specifically, when the crib 100 is unfolded, the second armrest 32 rotates downward around the second hinge point 211, from a folded state to an unfolded state, and the fourth positioning portion 213 is provided on the side of the second hinge point 211 away from the second vertical rod 20. When the second armrest 32 is in the unfolded state, the upper end of the fourth positioning portion 213 abuts against the lower end of the second armrest 32. When the second armrest 32 continues to rotate downward around the second hinge point 211, the upper end of the fourth positioning portion 213 restricts the second armrest 32 from continuing to rotate downward. The second armrest 32 is restricted in the unfolded state and cannot continue to rotate downward. The fourth positioning portion 213 realizes the positioning effect of the second armrest 32.

[0067] Optionally, the fourth positioning portion 213 can be a guide groove, and the two sides of the guide groove can be connected to the gap inside the second connecting member 21, so as to enhance the strength of the second connecting member 21, extend the service life and improve the reliability; the periphery above the guide groove can cooperate with the second armrest 32, and at the same time can limit the second armrest 32, restricting the second armrest 32 from rotating downward, thereby improving the reliability of the crib 100 in the unfolded state.

[0068] In some embodiments, the crib 100 also includes a third connecting member 12, which fixes the first vertical rod 10, a first end of the first support rod 33 is rotatably connected to the third connecting member 12, and a second end of the first support rod 33 is rotatably connected to the second end of the second armrest 32. When the crib 100 is folded, the second armrest 32 drives the first support rod 33 to rotate, and the first support rod 33 rotates around the third connecting member 12 to achieve folding of the first support rod 33; in addition, the crib 100 also includes a fourth connecting member 22, which fixes the second vertical rod 20, a first end of the second support rod 34 is rotatably connected to the fourth connecting member 22, and a second end of the second support rod 34 is rotatably connected to the second end of the first armrest 31. When the crib 100 is folded, the first armrest 31 drives the second support rod 34 to rotate, and the second support rod 34 rotates around the fourth connecting member 22 to achieve folding of the second support rod 34.

[0069] Specifically, the third connecting member 12 is passed through the first vertical rod 10, and the fourth connecting member 22 is passed through the second vertical rod 20. When the baby bed 100 is folded, the first vertical rod 10 and the second vertical rod 20 are closed together, and the second vertical rod 20 links the second armrest 32, and the second armrest 32 rotates upward around the first end of the second armrest 32, and the second end of the second armrest 32 pulls the second end of the first support rod 33, driving the first support rod 33 to rotate upward around the third connecting member 12 until the first support rod 33 is in a folded state; the first vertical rod 10 links the first armrest 31, and the first armrest 31 rotates upward around the first end of the first armrest 31, and the second end of the first armrest 31 pulls the second end of the second support rod 34, driving the second support rod 34 to rotate upward around the fourth connecting member 22 until the second support rod 34 is in a folded state.

[0070] Optionally, the third connecting member 12 may be disposed in the middle of the first upright pole 10, and the third connecting member 12 may be disposed below the first connecting member 11. The third connecting member 12 may have a fifth side portion and a sixth side portion, the fifth side portion may be perpendicular to the sixth side portion, the fifth side portion may extend in the left-right direction, and the sixth side portion may extend in the front-back direction, the first support rods 33 of the upper enclosure groups on the front and rear sides of the crib 100 may be rotatably connected to the fifth side portion, and the second support rods 34 of the upper enclosure groups on the left and right sides of the crib 100 may be rotatably connected to the sixth side portion.

[0071] Optionally, the fourth connecting member 22 may be disposed in the middle of the second upright 20, and the fourth connecting member 22 may be disposed below the second connecting member 21.

[0072] Optionally, the third connecting member 12 and the fourth connecting member 22 may be plastic parts. Plastic parts have a long service life, are light in weight and have a low production cost, which is helpful in reducing the weight of the crib 100 and reducing the manufacturing cost of the crib 100 .

[0073] Combination Figure 7In some embodiments, the third connecting member 12 includes a third hinge point 121 and a fifth positioning portion 122. The first end of the first support rod 33 is rotatably connected to the third hinge point 121. The fifth positioning portion 122 is closer to the first upright 10 than the third hinge point 121. In the unfolded state, the fifth positioning portion 122 is positioned above the first support rod 33. The first support rod 33 rotates around the third hinge point 121 between the unfolded state and the folded state. The fifth positioning portion 122 limits the first support rod 33 to prevent the first support rod 33 from rotating downward in the unfolded state, thereby improving the reliability of the stroller in the unfolded state.

[0074] Specifically, when the crib 100 is unfolded, the first support rod 33 rotates downward around the third hinge point 121, from a folded state to an unfolded state, and the fifth positioning portion 122 is provided at the upper end of the third connecting member 12. When the first support rod 33 is in the unfolded state, the lower end of the fifth positioning portion 122 abuts against the upper end of the first support rod 33. When the first support rod 33 continues to rotate downward around the third hinge point 121, the lower end of the fifth positioning portion 122 restricts the first support rod 33 from continuing to rotate downward. The first support rod 33 is restricted in the unfolded state and cannot continue to rotate downward. The fifth positioning portion 122 realizes the positioning effect on the first support rod 33.

[0075] In addition, combined Figure 8 The fourth connecting member 22 includes a fourth hinge point 221 and a sixth positioning portion 222. The first end of the second support rod 34 is rotatably connected to the fourth hinge point 221. The sixth positioning portion 222 is closer to the second vertical rod 20 than the fourth hinge point 221. In the unfolded state, the sixth positioning portion 222 is positioned above the second support rod 34. The second support rod 34 rotates around the fourth hinge point 221 between the unfolded state and the folded state. The sixth positioning portion 222 limits the second support rod 34 to prevent the second support rod 34 from rotating downward in the unfolded state, so that the structure of the baby bed 100 is more solid in the unfolded state.

[0076] Specifically, when the crib 100 is unfolded, the second support rod 34 rotates downward around the fourth hinge point 221, from a folded state to an unfolded state, and the sixth positioning portion 222 is provided at the upper end of the fourth connecting member 22. When the second support rod 34 is in the unfolded state, the lower end of the sixth positioning portion 222 abuts against the upper end of the second support rod 34. When the second support rod 34 continues to rotate downward around the fourth hinge point 221, the lower end of the sixth positioning portion 222 restricts the second support rod 34 from continuing to rotate downward. The second support rod 34 is restricted in the unfolded state and cannot continue to rotate downward. The sixth positioning portion 222 realizes the positioning effect on the second support rod 34.

[0077] Optionally, the fifth positioning portion 122 and the sixth positioning portion 222 can be ribs, which can connect the gaps inside the third connecting member 12 and the fourth connecting member 22, enhance the strength of the third connecting member 12 and the fourth connecting member 22, extend the service life and improve the reliability; the periphery below the ribs can cooperate with the first support rod 33 and the second support rod 34, and at the same time can limit the first support rod 33 and the second support rod 34, restricting the first support rod 33 and the second support rod 34 from rotating downward, thereby ensuring the stability of the crib 100 when it is in the unfolded state.

[0078] Combination Figure 4 In some embodiments, the first support rod 33 includes a first rod portion 331 and a second rod portion 332 connected along the length direction, the first rod portion 331 is rotatably connected to the first upright rod 10, and the second rod portion 332 is arranged on the inner side of the extended position of the first rod portion 331 and is hingedly connected to the second end of the second armrest 32. The first rod portion 331 of the first support rod 33 is provided with a bending portion, which can be bent toward the inner side of the second armrest 32, the second rod portion 332 extends in the direction of the bending of the first rod portion 331, and the top end of the second rod portion 332 can be hingedly connected to the inner side of the second end of the second armrest 32. The center of gravity of the first support rod 33 is located on the inner side of the crib 100, which reduces the swaying and shaking of the second armrest 32 when subjected to force, making the structure of the crib 100 more stable; when the crib 100 is in a folded state, the second rod portion 332 can be located on the inner side of the second armrest 32, thereby saving external space.

[0079] For example, when the baby crib 100 is in the unfolded state, two groups of adjacent first vertical poles 10 and second vertical poles 20 are symmetrically arranged along the front-to-back direction, an upper encircling group is arranged between the first vertical poles 10 and the second vertical poles 20, the spacing between the front and rear groups of second armrests 32 is greater than the spacing between the front and rear groups of second rod portions 332, and the second rod portion 332 is located inside the second armrest 32. A portion of the first rod portion 331 is located inside the second armrest 32, and the other portion is located in the same plane as the first vertical pole 10. The total weight of the first rod portion 331 and the second rod portion 332 located inside the second armrest 32 is greater than the weight of the portion of the first rod portion 331 and the first vertical pole 10 located in the same plane, and the center of gravity of the first support rod 33 is located inside the second armrest 32. When the baby crib 100 is in the unfolded state, the second rod portion 332 of the first support rod 33 supports the second armrest 32. When the second armrest 32 is shaken outward by force, the first support rod 33 reduces the outward tilt angle of the second armrest 32 to prevent the baby crib 100 from tipping over.

[0080] In addition, the second rod portion 332 is located on the inner side of the second armrest 32, which ensures the flatness of the outer side of the crib 100 and makes the appearance structure of the crib 100 more beautiful; when the crib 100 is in the folded state, the second rod portion 332 is located on the inner side of the second armrest 32, thereby saving external space.

[0081] In some embodiments, the second support rod 34 includes a third rod portion 341 and a fourth rod portion 342 connected along the length direction, the third rod portion 341 is rotatably connected to the second upright rod 20, and the fourth rod portion 342 is disposed inside the extended position of the third rod portion 341 and is hingedly connected to the second end of the first armrest 31. The third rod portion 341 of the second support rod 34 is provided with a bent portion, which can be bent toward the inside of the first armrest 31, the fourth rod portion 342 extends in the direction of the bending of the third rod portion 341, and the top end of the fourth rod portion 342 can be hingedly connected to the inside of the second end of the first armrest 31. The center of gravity of the second support rod 34 is located inside the crib 100, which reduces the swaying and shaking of the first armrest 31 when subjected to force, and ensures the structural firmness of the crib 100; when the crib 100 is in the folded state, the fourth rod portion 342 is located inside the first armrest 31, thereby saving external space.

[0082] For example, when the baby crib is in the unfolded state, two groups of adjacent second vertical rods 20 and second vertical rods 20 are symmetrically arranged in the front-to-back direction, an upper encircling group is arranged between the second vertical rods 20 and the second vertical rods 20, the spacing between the front and rear groups of first armrests 31 is greater than the spacing between the front and rear groups of fourth rod portions 342, and the fourth rod portion 342 is located inside the first armrest 31. A portion of the third rod portion 341 is located inside the first armrest 31, and the other portion is located in the same plane as the second vertical rod 20. The total weight of the third rod portion 341 and the fourth rod portion 342 located inside the first armrest 31 is greater than the weight of the portion of the third rod portion 341 and the second vertical rod 20 located in the same plane, and the center of gravity of the second support rod 34 is located inside the first armrest 31. When the baby crib 100 is in the unfolded state, the fourth rod portion 342 of the second support rod 34 supports the first armrest 31. When the first armrest 31 is shaken outward by force, the second support rod 34 reduces the outward tilt angle of the first armrest 31 to prevent the baby crib 100 from tipping over. The fourth rod portion 342 is located on the inner side of the first armrest 31 , which ensures the flatness of the outer side of the crib 100 and makes the appearance of the crib 100 more beautiful.

[0083] In addition, when the crib 100 is in the folded state, the fourth rod portion 342 is located on the inner side of the first armrest 31, the extension length of the bent portion of the first rod portion 331 is greater than the extension length of the bent portion of the third rod portion 341, the second rod portion 332 extends in the direction of the bending of the first rod portion 331, and a clearance space can be formed on the front side of the second rod portion 332. The fourth rod portion 342 can be located in the clearance space on the front side of the second rod portion 332, so that the second rod portion 332 and the fourth rod portion 342 are closer together on the inner sides of the first armrest 31 and the second armrest 32, thereby saving external space.

[0084] Optionally, the length of the bent portion of the third rod portion 341 may also be greater than the length of the bent portion of the first rod portion 331, and a clearance space may be formed on the front side of the fourth rod portion 342. The second rod portion 332 may be located in the clearance space on the front side of the fourth rod portion 342, so that the second rod portion 332 and the fourth rod portion 342 can be closer together, thereby reducing the occupied space after the crib 100 is folded.

The base frame group includes a plurality of bottom support rods 41, one ends of the plurality of bottom support rods 41 are rotatably connected to the plurality of vertical poles respectively, and the other ends of the plurality of bottom support rods 41 are rotatably connected to each other. When the crib 100 is folded, the plurality of bottom support rods 41 drive the plurality of vertical poles to move closer to each other to a folded state, thereby realizing the folding of the crib 100.

[0086] Specifically, when the crib 100 is folded, the other ends of the multiple bottom support rods 41 are pulled upward, the other ends of the multiple bottom support rods 41 are folded together, one end of the multiple bottom support rods 41 rotates upward around one end of the multiple vertical rods, and one end of the multiple bottom support rods 41 drives the multiple vertical rods to close together. The multiple vertical rods include adjacent first vertical rods 10 and second vertical rods 20, and an upper surrounding group is provided between the first vertical rods 10 and the second vertical rods 20. The first vertical rods 10 and the second vertical rods 20 are closed together, and the first vertical rod 10 drives the first armrest 31 to rotate around the first armrest 31. The first end rotates upward, and the second end of the first armrest 31 is linked to the second end of the second support rod 34, driving the second support rod 34 to rotate upward around the first end of the second support rod 34; the second vertical rod 20 drives the second armrest 32 to rotate upward around the first end of the second armrest 32, and the second end of the second armrest 32 is linked to the second end of the first support rod 33, driving the first support rod 33 to rotate upward around the first end of the first support rod 33, and the first support rod 33 and the second support rod 34 rotate with each other and close together, finally realizing the folding of the baby bed 100.
