Description

Technical Field

[0001] This application relates to the field of children's products technology, and more particularly to a children's bed. Background Technology

[0002] A children's bed provides a space for children to sleep or play. Children's beds can be folded for storage to enhance convenience. Existing children's beds include a base structure, support legs, and foldable railings located at the top of the support legs. When unfolded, the base structure moves downwards, causing the support legs to move outwards until the folded railings are extended. However, during unfolding, the high degree of freedom of the railings means that the top of the support legs is unstable and prone to tilting, increasing the difficulty of unfolding the children's bed.

[0003] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art by providing a children's bed.

[0006] In one embodiment, when the children's bed is in its unfolded state, the first railings on both sides of the connector are horizontally arranged; when the children's bed is in its temporarily fixed state, the first railings on both sides of the connector are in a U-shape.

[0007] In one embodiment, when the children's bed is in the unfolded form, the first railings on both sides of the connector are horizontally arranged; when the children's bed is in the temporarily fixed form, the first railings on both sides of the connector are V-shaped.

[0008] In one embodiment, the sliding groove has a second guide groove segment and a first guide groove segment arranged vertically and interconnected. The groove walls of the first guide groove segment and the second guide groove segment are set at an angle, and the angle is not equal to 180°. When the children's bed is in the folded state, the connecting pin of the first railing slides into the first guide groove segment. When the children's bed is in the temporary fixed state, the connecting pin of the first railing slides into the second guide groove segment.

[0009] In one embodiment, the sliding groove further includes a limiting groove section, and the second guide groove section is disposed between the first guide groove section and the limiting groove section; when the children's bed is in the unfolded state, the connecting pin of the first railing is engaged with the limiting groove section.

[0010] In one embodiment, the length of the first guide groove is substantially equal to the length of the second guide groove.

[0011] In one embodiment, the first limiting member is a snap-fit ​​pin, the second limiting member is a snap-fit ​​hole, the snap-fit ​​pin is connected to the first retaining rod by a spring, and the snap-fit ​​hole is disposed in the connector; the snap-fit ​​pin has an inclined surface; the inclined surface of the snap-fit ​​pin slides against the wall of the snap-fit ​​hole.

[0012] In one embodiment, the fence group is provided in four groups, and the fence groups arranged opposite to each other are provided with the limiting structure.

[0013] In one embodiment, in the enclosure rod group with the limiting structure, the length of the first enclosure rod is a first length; in the enclosure rod group without the limiting structure, the length of the first enclosure rod is a second length; the first length is less than the second length.

[0014] In one embodiment, the railing assembly further includes a second railing. When the children's bed is in the unfolded state, the second railing is located below the first railing, and one end of the second railing is hinged to the connector and the other end is hinged to the top of the support leg.

[0015] The beneficial effects of this application are: by the snap-fit ​​between the first limiting member and the second limiting member, the relative position between the connecting member and the first rail is restricted, that is, the connecting member and the first rail are relatively stationary, which can maintain the stability of the rail group during the transformation of the children's bed, avoid excessive tilting of the top of the support leg during the transformation, reduce the difficulty of the operation of the transformation of the children's bed, and improve the user experience.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0038] The children's bed in this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] In existing technologies, the high degree of freedom of the support rods during the unfolding process means that the top of the support legs is unstable and easily tilts to one side, increasing the difficulty of unfolding the children's bed.

[0040] To address the aforementioned technical problems, this application provides a children's bed, including a base frame assembly, a railing assembly, support legs, and a limiting structure. The base frame assembly includes a base and bottom rods spaced apart around the base, the bottom rods being hinged to the base. The railing assembly includes a connector and two first rails arranged opposite each other, the connector having a sliding groove into which the first rails slide. One end of each support leg is hinged to the end of the bottom rod away from the base, and the other end is hinged to the end of the first rail away from the connector. The limiting structure includes a first limiting member and a second limiting member, the first limiting member being disposed on one of the connector and the first rail, and the second limiting member being disposed on the other of the connector and the first rail. The children's bed has an unfolded form and a folded form. During the switching between the unfolded and folded forms, the first limiting member and the second limiting member are configured to engage with each other, so that the children's bed is in a temporarily fixed form. This will be described in detail below.

[0041] See Figure 1 , Figure 3 , Figure 4 , Figure 8 and Figure 9 The children's bed includes a base frame assembly 10, a railing assembly 20, support legs 30, and a limiting structure 40. The base frame assembly 10 includes a base 11 and base rods 12 spaced around the base 11, with the base rods 12 hinged to the base 11. The railing assembly 20 includes a connector 21 and two first rails 22 arranged opposite each other. The connector 21 has a sliding groove 211, and the first rails 22 slide in the sliding groove 211. One end of the support leg 30 is hinged to the end of the base rod 12 away from the base 11, and the other end is hinged to the first rail 22. 2. The end away from the connector 21; the limiting structure 40 includes a first limiting member 41 and a second limiting member 42, the first limiting member 41 is disposed on one of the connector 21 and the first surrounding rod 22, and the second limiting member 42 is disposed on the other of the connector 21 and the first surrounding rod 22; the children's bed has an unfolded form and a folded form, and during the switching between the unfolded form and the folded form, the first limiting member 41 and the second limiting member 42 are configured to engage with each other so that the children's bed is in a temporary fixed form.

[0042] When the children's bed is in a temporary fixed position, the interlocking action between the first limiting member 41 and the second limiting member 42 restricts the relative position between the connecting member 21 and the first surrounding rod 22, that is, the connecting member 21 and the first surrounding rod 22 are relatively stationary. This can maintain the stability of the surrounding rod assembly 20 during the transformation of the children's bed, prevent the top of the support leg 30 from tilting excessively during the transformation, reduce the difficulty of the operation of the children's bed transformation, and improve the user experience.

[0043] When there is no limiting structure 40, the children's bed will move the base 11 downwards directly when changing its form. The first rail 22 will move relative to the connecting piece 21, making the top of the children's bed unstable. The rail group 20 has a large degree of freedom, making the support leg 30 easy to tilt. The children's bed cannot be unfolded smoothly, increasing the difficulty of unfolding the children's bed.

[0044] When preparing to unfold the children's bed, the connector 21 is moved upward until the first limiting member 41 and the second limiting member 42 engage, thereby limiting the relative position between the first support rod 22 and the connector 21 and ensuring the stability of the top of the children's bed (the top of the support leg 30). Then, the base 11 is moved downward, and the base 11 drives the bottom rod 12 to push the bottom of the support leg 30 outward (away from the connector 21, the same below). At this time, the children's bed is close to unfolded. The engagement between the first limiting member 41 and the second limiting member 42 is released, and the base 11 continues to move downward, so that the support leg 30 continues to move outward. During the movement of the support leg 30, the first support rod 22 moves relative to the connector 21 until the children's bed is in unfolded.

[0045] It should be noted that in some embodiments, a connecting sleeve is provided at each end of the support leg 30. The support leg 30 is hinged to the base rod 12 and the first surrounding rod 22 through the connecting sleeve, which can protect the ends of the support leg 30, the base rod 12 and the first surrounding rod 22 and prevent injury to the user.

[0046] In some embodiments, the support rod assembly 20 further includes a second support rod 23. When the children's bed is in the unfolded state, the second support rod 23 is located at the bottom of the first support rod 22, and one end of the second support rod 23 is hinged to the support leg 30 and the other end is hinged to the connector 21. By setting the second support rod 23, it can be ensured that when the children's bed is unfolded, the first support rod 22 can smoothly enter the limiting groove section 2111.

[0047] See Figure 10 and Figure 11 In some embodiments, the first limiting member 41 and the second limiting member 42 may be a snap-fit ​​pin 53 (first limiting member 41) and a snap-fit ​​hole 54 (second limiting member 42). The snap-fit ​​pin 53 is mounted on the first retaining rod 22 by a spring 51, and the snap-fit ​​hole 54 is mounted on the connector 21. The snap-fit ​​pin 53 has a bevel 531, which slides against the wall of the snap-fit ​​hole 54.

[0048] In use, first move the connector 21 upwards, the first retaining rod 22 rotates relative to the connector 21, the locking pin 53 contacts the side wall of the connector 21, the spring 51 is compressed, and the locking pin 53 is compressed and retracted by the side wall of the connector 21. Continue to rotate the first retaining rod 22, and the locking pin 53 moves to be positioned opposite to the locking hole 54. Under the action of the spring 51, the locking pin 53 is locked in the locking hole 54, thereby restricting the connection between the connector 21 and the first retaining rod 22. In the subsequent form switching process, as the support leg 30 moves outwards, the first retaining rod 22 rotates relative to the connector 21, and the locking pin 53 moves out of the locking hole 54 (that is, the locking state between the first limiting member 41 and the second limiting member 42 is released), and the locking state between the first limiting member 41 and the second limiting member 42 can be unlocked without manual intervention.

[0049] When the children's bed is in its unfolded position, the locking pin 53 is pressed against the side wall of the connector 21 under the action of the spring 51, increasing the static friction between the connector 21 and the locking pin 53 (e.g., Figure 8 and Figure 9 As shown, this is beneficial to the stability of the relative position between the first retaining rod 22 and the connecting piece 21, that is, to the stability of the unfolded form of the children's bed; and during the process of switching the children's bed from the temporary fixed form to the unfolded form, the locking pin 53 is always pressed against the side wall of the connecting piece 21, which is beneficial to the stability of the children's bed during the form switching process.

[0050] It should be noted that the locking pin 53 is installed and fixed by the mounting part 52 set inside the first retaining rod 22. The mounting part 52 has a mounting hole, and the spring 51 and the locking pin 53 are set in the mounting hole. The mounting hole can limit the deformation of the spring 51 in the radial direction of the mounting hole to a certain range (determined by the diameter of the mounting hole), which is beneficial to the stability of the locking pin 53, thereby achieving the stability of the temporary fixed form of the children's bed (the locking pin 53 is stably inserted into the locking hole 54). In addition, the inclined surface 531 of the locking pin 53 can facilitate the movement of the locking pin 53 toward the spring 51 when the locking pin 53 contacts the connecting part 21, and can automatically realize the entry and exit of the locking pin 53 into the locking hole 54 during the form switching process; the inclined surface 531 can be a conical surface, a spherical surface, or other shapes.

[0051] In some embodiments, the engagement between the card pin 53 and the card slot 54 may not be automatically switched; such as Figure 12 As shown, the card pin 53 does not have an inclined surface 531, which is a cylindrical surface (or Figure 12 (e.g., the horizontal plane in the field of view), when it is necessary to release the temporary fixed form of the children's bed, it is necessary to manually move the card pin 53 to the left so that the card pin 53 exits the card hole 54.

[0052] See Figure 3 and Figure 4When the children's bed is in the unfolded state, the first rails 22 on both sides of the connector 21 are horizontally arranged; when the children's bed is in the temporarily fixed state, the first rails 22 on both sides of the connector 21 are in a Λ shape.

[0053] When the first limiting member 41 and the second limiting member 42 are engaged, the children's bed is in a temporarily fixed state. The first railings 22 on both sides of the connector 21 are in a U-shape. When the relative position between the first railings 22 and the connector 21 is restricted, the connector 21 is located above the children's bed (e.g., Figure 3 As shown, during the transition of the children's bed from its temporary fixed form to its unfolded form, the connecting piece 21 moves downward until the first rail 22 is horizontally positioned. When the children's bed needs to be folded up, the connecting piece 21 moves directly downward, and the first rails 22 on both sides of the connecting piece 21 rotate relative to the connecting piece 21. During the folding up process, the first rails 22 and the connecting piece 21 do not pass through a restricted state (i.e., the first rails 22 on both sides of the connecting piece 21 are in a Λ-shaped state). In other words, during the folding up process, the first limiting piece 41 and the second limiting piece 42 do not restrict the first rails 22 and the connecting piece 21, allowing the children's bed to be folded up smoothly and quickly.

[0054] It should be noted that in this embodiment, when the first rail 22 is unfolded to a horizontal state, the children's bed is in the unfolded form; in some embodiments, when the children's bed is in the unfolded form, the first rails 22 on both sides of the connector 21 can also be set at an angle (not an angle of 180°), and the two first rails 22 are not parallel, but not limited to this.

[0055] In some embodiments, when the children's bed is in its unfolded state, the first side rails 22 on both sides of the connector 21 are horizontally arranged; when the children's bed is in its temporarily fixed state, the first side rails 22 on both sides of the connector 21 are V-shaped, such as... Figure 13 As shown ( Figure 13 Only schematic diagrams related to the retaining wall assembly 20 are provided.

[0056] When the children's bed is in the temporary fixed state, the first rails 22 on both sides of the connector 21 are V-shaped. During the process of the children's bed switching from the temporary fixed state to the unfolded state, the connector 21 moves upward until the first rails 22 on both sides of the connector 21 are horizontally set. With this setting, the connector 21 does not need to be raised above the children's bed, and it can improve the stability of the top of the children's bed during unfolding and the stability of the children's bed during folding.

[0057] When the children's bed begins to fold from its unfolded state, the connecting piece 21 moves downward, the horizontally positioned first rail 22 rotates into a V-shape, and the first limiting piece 41 and the second limiting piece 42 engage. Then, the base 11 is pulled upward, and the bottom of the support leg 30 is folded inward through the bottom rod 12. The engagement between the first limiting piece 41 and the second limiting piece 42 is then released, and the connecting piece 21 continues to move downward until the children's bed is in its folded state. This improves the stability of the rail assembly 20 during the folding process and prevents instability at the top of the children's bed during folding.

[0058] See Figure 4-6 The sliding groove 211 has a second guide groove section 2113 and a first guide groove section 2112 arranged vertically and interconnected. The groove walls of the first guide groove section 2112 and the second guide groove section 2113 are set at an angle, and the angle is not equal to 180°. When the children's bed is in the folded state, the connecting pin of the first guard rod 22 is slidably connected to the first guide groove section 2112. When the children's bed is in the temporary fixed state, the first guard rod 22 is connected to the second guide groove section 2113.

[0059] By setting the first guide groove section 2112 and the second guide groove section 2113 at an angle, the difficulty of the first guide rod 22 sliding from the first guide groove section 2112 to the second guide groove section 2113 is increased, that is, the first guide rod 22 is not easy to slide from the first guide groove section 2112 into the second guide groove section 2113.

[0060] During the actual unfolding of the children's bed, there may be instances of misoperation or confusion regarding how to unfold the bed. For example, the base 11 might be moved downwards. As the base 11 moves, the first support rod 22 slides from the first guide groove section 2112 towards the second guide groove section 2113. When it reaches the connection point between the first guide groove section 2112 and the second guide groove section 2113 (the connecting pin of the first support rod 22 slides to the connection point), the sliding is restricted because the groove walls connecting the first guide groove section 2112 and the second guide groove section 2113 are angled. The connecting pin of the first guide rod 22 cannot smoothly enter the second guide groove 2113, meaning the base 11 cannot continue to move downwards to unfold the children's bed. At this time, the first limiting member 41 and the second limiting member 42 have not yet reached the engagement position. If the base 11 continues to move downwards, the top of the children's bed will continue to expand outwards, which may cause wobbling. The groove walls connecting the first guide groove 2112 and the second guide groove 2113 are set at an angle, which restricts the connecting pin of the first guide rod 22 from continuing to move, thus preventing the top of the children's bed from wobbling (the support leg 30 tilts) due to misoperation, which is not conducive to improving the user experience.

[0061] In this embodiment, the connector 21 needs to be moved upward until the first limiting member 41 and the second limiting member 42 engage, temporarily fixing the first rail 22 and the connector 21. Then, the base 11 is moved downward to unfold the children's bed. In this embodiment, before moving the connector 21 upward to the temporary fixed position of the children's bed, the base 11 can be moved downward until the connecting pin of the first rail 22 engages at the connection between the first guide groove section 2112 and the second guide groove section 2113. At this time, the support legs 30 of the children's bed will have a certain displacement in all directions, providing operating space for moving the connector 21 upward. This facilitates the upward movement of the connector 21. After the support legs 30 have a certain displacement in all directions, the included angle between the two first rails 22 in the same rail group 20 becomes larger, making it easier to move the connector 21 upward. The subsequent unfolding operation of the children's bed will not be described in detail here.

[0062] It should be noted that the connecting pin of the first retaining rod 22 is used for the first retaining rod 22 to slide in the sliding groove 211, which is not shown in the figure.

[0063] In some embodiments, the sliding groove 211 further includes a limiting groove section 2111, and a second guide groove section 2113 is disposed between the first guide groove section 2112 and the sliding groove 211; when the children's bed is in the unfolded state, the connecting pin of the first rail 22 is engaged with the limiting groove section 2111.

[0064] By setting the limiting groove 2111, the stability of the children's bed in the unfolded form can be guaranteed. During the process of the children's bed switching from the temporary fixed form to the unfolded form, the connecting pin of the first rail 22 can slide into the limiting groove 2111 from the second guide groove 2113 and be engaged in the limiting groove 2111. The stability of the children's bed in the unfolded form can be achieved without additional structure.

[0065] In some embodiments, the length of the first guide groove segment 2112 is substantially equal to the length of the second guide groove segment 2113.

[0066] When the children's bed is in the folded state, the connecting pin of the first support rod 22 slides into the first guide groove section 2112. When the children's bed is in the unfolded state, the connecting pin of the first support rod 22 slides into the limiting groove section 2111. When the connecting pin of the first support rod 22 is at the connection between the first guide groove section 2112 and the second guide groove section 2113, and since the length of the first guide groove section 2112 and the length of the second guide groove section 2113 are basically equal, the children's bed is in a semi-unfolded state between the folded and unfolded states. When the children's bed is in the semi-unfolded state, the distance between the support legs 30 is not far, and the children's bed has a certain degree of stability. At the same time, it also provides sufficient operating space for moving the connector 21 upward. When the children's bed is in the semi-unfolded state, the first support rods 22 on both sides of the connector 21 can rotate more easily relative to the connector 21, reducing the labor intensity when moving the connector 21 upward.

[0067] When the length of the first guide groove segment 2112 is less than the length of the second guide groove segment 2113, and the connecting pin of the first retaining rod 22 is engaged between the first guide groove segment 2112 and the second guide groove segment 2113, the children's bed is in a state between the folded state and the semi-open state. The ends of the first retaining rods 22 on both sides of the connector 21 that are far from the connector 21 are relatively close (the included angle between the first retaining rods 22 on both sides of the connector 21 is small), which increases the difficulty of the connector 21 moving upward. When the length of the first guide groove segment 2112 is greater than the length of the second guide groove segment 2113, and the first retaining rod 22 is engaged between the first guide groove segment 2112 and the second guide groove segment 2113, the children's bed is in a state between the semi-open state and the open state. The top of the children's bed has a large opening range, and the top of the children's bed is unstable, which is not conducive to the opening operation of the children's bed.

[0068] It should be noted that in this embodiment, the unfolding operation of the children's bed is as follows: first, the base 11 is moved downward until the connecting pin of the first rail 22 is engaged between the first guide groove section 2112 and the second guide groove section 2113; then, the connecting piece 21 is moved upward until the first limiting piece 41 and the second limiting piece 42 engage; finally, the base 11 is moved downward to achieve the full unfolding of the children's bed.

[0069] In addition, the length of the first guide groove segment 2112 is basically equal to the length of the second guide groove segment 2113, or the length of the first guide groove segment 2112 is slightly greater than or slightly less than the length of the second guide groove segment 2113.

[0070] See Figure 2 When the children's bed is in the folded position, the first rails 22 on both sides of the connector 21 form a V-shape.

[0071] The first rails 22 on both sides of the connector 21 are V-shaped, that is, the distance between the two first rails 22 is set to be wider at the top and narrower at the bottom. The upper width provides operating space for moving the connector 21 upward, making it convenient for the user to operate; at the same time, the V-shape is set so that when the connector 21 is moved upward (the first rails 22 on both sides of the connector 21 rotate to both sides), it is beneficial for the first rails 22 to rotate to the side away from the connector 21, reducing the labor intensity when moving the connector 21 upward.

[0072] In some embodiments, the fence group 20 is provided in four groups, and the fence group 20 arranged opposite to each other is provided with a limiting structure 40.

[0073] By setting the surrounding rod assembly 20 with a limiting structure 40, when the first surrounding rod 22 and the connecting member 21 are limited by the first limiting member 41 and the second limiting member 42, it can ensure that the force on both sides of the children's bed is uniform, which is conducive to the stability of the children's bed during the unfolding process; and during the unfolding process of the children's bed, it is convenient for the operator to operate the connecting member 21 on both sides of the children's bed at the same time, which is conducive to the smooth unfolding of the children's bed.

[0074] In some embodiments, in a rod group 20 with a limiting structure 40, the length of the first rod 22 is a first length; in a rod group 20 without a limiting structure 40, the length of the first rod 22 is a second length; the first length is less than the second length.

[0075] The limiting structure 40 is located on the shorter first support rod 22. When the children's bed is in the folded state, the connector 21 connected to the shorter first support rod 22 is positioned higher, making it easier for the operator to touch during the unfolding operation. The connector 21 on the longer first support rod 22 is less likely to be touched. This arrangement facilitates the unfolding operation of the children's bed. At the same time, when switching the children's bed from the folded state to the temporary fixed state, the connector 21 needs to be moved upward. During the upward movement of the connector 21, the first support rod 22 will push the support leg 30 outward. The longer first support rod 22 will push the support leg 30 outward a greater distance. When the limiting structure 40 is located on the longer first support rod 22, the support leg 30 needs to move a greater distance to achieve the switch of the children's bed from the folded state to the temporary fixed state.

[0076] On the other hand, this application also relates to a method for unfolding a children's bed, comprising the following steps: the children's bed is in a folded state; a connector 21 with a limiting structure 40 is driven to move upward, and while the connector 21 moves upward, the first retaining rod 22 pushes the top of the support leg 30 to move away from the connector 21; until the first limiting member 41 and the second limiting member 42 engage and are temporarily fixed together, and the top of the adjacent support leg 30 is temporarily fixed, the children's bed is in a temporarily fixed state; the base 11 is driven to move downward, and the bottom rod 12 moves the bottom of the support leg 30 to the side away from the base 11, the base frame assembly 10 is opened, and the engagement between the first limiting member 41 and the second limiting member 42 is released; the base 11 is driven to continue moving downward until the children's bed is in an unfolded state.

[0077] When the children's bed is in a temporary fixed position, the interlocking action between the first limiting member 41 and the second limiting member 42 restricts the relative position between the connecting member 21 and the first surrounding rod 22, that is, the connecting member 21 and the first surrounding rod 22 are relatively stationary. This can maintain the stability of the surrounding rod assembly 20 during the transformation of the children's bed, prevent the top of the support leg 30 from tilting excessively during the transformation, reduce the difficulty of the operation of the children's bed transformation, and improve the user experience.

[0078] When there is no limiting structure 40, the children's bed will move the base 11 downwards directly when changing its form. The first rail 22 will move relative to the connecting piece 21, making the top of the children's bed unstable. The rail group 20 has a large degree of freedom, making the support leg 30 easy to tilt. The children's bed cannot be unfolded smoothly, increasing the difficulty of unfolding the children's bed.

[0079] In some embodiments, the first limiting member 41 and the second limiting member 42 engage in a locking manner, including: the locking pin 53 moving into the locking hole 54; releasing the locking engagement between the first limiting member 41 and the second limiting member 42, including: the base 11 being driven to continue moving downward, the bottom of the support leg 30 continuing to move away from the side of the base 11, the top of the support leg 30 driving the first retaining rod 22 to move relative to the connector 21, the inclined surface 531 of the locking pin 53 slidingly engaging with the hole wall of the locking hole 54, and exiting from the locking hole 54.

[0080] The inclined surface 531 of the snap-fit ​​pin 53 allows the snap-fit ​​pin 53 to move under pressure when it comes into contact with the connector 21, and can automatically move the snap-fit ​​pin 53 into and out of the snap-fit ​​hole 54 during the shape switching process; the inclined surface 531 can be a conical surface, a spherical surface or other shapes.

[0081] In some embodiments, the base 11 is driven to continue moving downward, the bottom of the support leg 30 continues to move to the side away from the base 11, and the top of the support leg 30 drives the first arm 22 to move relative to the connector 21, including: the support leg 30 rotating relative to the second arm 23, and the top of the support leg 30 driving the first arm 22 to move toward the connector 21.

[0082] It should be noted that when the children's bed is in the unfolded state, the second support rod 23 is located at the bottom of the first support rod 22, and one end of the second support rod 23 is hinged to the support leg 30 and the other end is hinged to the connector 21. The setting of the second support rod 23 can ensure that the first support rod 22 can smoothly enter the limiting groove section 2111 when the children's bed is unfolded.

[0083] In some embodiments, before driving the connector 21 with the limiting structure 40 to move upward, the method further includes: driving the base 11 to move downward, and driving the bottom rod 12 to move the bottom of the support leg 30 to the side away from the base 11; the top of the support leg 30 drives the first surrounding rod 22 to move relative to the connector 21, so that the connecting pin of the first surrounding rod 22 slides in cooperation with the first guide groove section 2112 until the connecting pin of the first surrounding rod 22 is engaged at the connection between the first guide groove section 2112 and the second guide groove section 2113; driving the connector 21 to move upward, while the connector 21 moves upward, it pushes the first surrounding rod 22 to move the top of the support leg 30 away from the connector 21; the connecting pin of the first surrounding rod 22 slides toward the second guide groove section 2113, thereby releasing the engagement of the connecting pin of the first surrounding rod 22 at the connection between the first guide groove section 2112 and the second guide groove section 2113.

[0084] During the actual unfolding of the children's bed, there may be instances of misoperation or confusion regarding how to unfold the bed. For example, the base 11 might be moved downwards. As the base 11 moves, the first support rod 22 slides from the first guide groove section 2112 towards the second guide groove section 2113. When it reaches the connection point between the first guide groove section 2112 and the second guide groove section 2113 (the connecting pin of the first support rod 22 slides to the connection point), the sliding is restricted because the groove walls connecting the first guide groove section 2112 and the second guide groove section 2113 are angled. The connecting pin of the first guide rod 22 cannot smoothly enter the second guide groove 2113, meaning the base 11 cannot continue to move downwards to unfold the children's bed. At this time, the first limiting member 41 and the second limiting member 42 have not yet reached the engagement position. If the base 11 continues to move downwards, the top of the children's bed will continue to expand outwards, which may cause wobbling. The groove walls connecting the first guide groove 2112 and the second guide groove 2113 are set at an angle, which restricts the connecting pin of the first guide rod 22 from continuing to move, thus preventing the top of the children's bed from wobbling (the support leg 30 tilts) due to misoperation, which is not conducive to improving the user experience.

[0085] In this embodiment, before moving the connector 21 upward to the temporary fixed position of the children's bed, the base 11 can be moved downward until the connecting pin of the first guide rod 22 is engaged at the connection between the first guide groove section 2112 and the second guide groove section 2113. At this time, the support legs 30 of the children's bed will have a certain displacement in all directions, providing operating space for moving the connector 21 upward. This facilitates the upward movement of the connector 21. After the support legs 30 have a certain displacement in all directions, the included angle between the two first guide rods 22 in the same guide rod group 20 becomes larger, making it easier to move the connector 21 upward. The subsequent unfolding operation of the children's bed will not be described here.

[0086] It should be noted that in some embodiments, before the aforementioned unfolding step of the children's bed, the base 11 needs to be unlocked. The base 11 includes an upper support and a lower support that are nested together, which will not be described in detail here.

[0087] The technical solution provided in this application aims to limit the relative position between the connecting member 21 and the first retaining rod 22 through the snap-fit ​​cooperation between the first retaining member 41 and the second retaining member 42. That is, the connecting member 21 and the first retaining rod 22 are relatively stationary. This can maintain the stability of the retaining rod group 20 during the transformation of the children's bed, prevent the top of the support leg 30 from tilting excessively during the transformation, reduce the difficulty of the operation of the transformation of the children's bed, and improve the user experience.
