[0040] In the description of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.
[0041] The children's bed and the unfolding method of the children's bed in the present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0042] In the prior art, during the unfolding process, the freedom degree of the railing is high, that is, the top of the support leg is unstable and prone to swaying, which increases the difficulty of unfolding the children's bed.
[0043] To solve the above technical problems, an embodiment of the present application provides a children's bed, including a chassis assembly, a railing group, support legs, and a limiting structure; the chassis assembly includes a base and bottom rods spaced around the base, and the bottom rods are hinged to the base; the railing group includes a connecting member and two first railings arranged oppositely, the connecting member is provided with a sliding groove, and the first railing is slidably connected to the sliding groove; one end of the 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 railing away from the connecting member; the limiting structure includes a first limiting member and a second limiting member, the first limiting member is arranged on one of the connecting member and the first railing, and the second limiting member is arranged on the other of the connecting member and the first railing; the children's bed has an unfolded form and a folded form, and during the process of the children's bed switching between the unfolded form and the folded form, the first limiting member and the second limiting member are configured to be clamped and matched with each other to make the children's bed in a temporarily fixed form. The following is a detailed description.
[0044] Refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 8 and Figure 9, the baby cot includes a chassis assembly 10, a railing group 20, support legs 30 and a limiting structure 40; the chassis assembly 10 includes a base 11 and bottom rods 12 spaced around the periphery of the base 11, and the bottom rods 12 are hinged to the base 11; the railing group 20 includes a connecting member 21 and two first railings 22 arranged opposite to each other, and the connecting member 21 is provided with a sliding groove 211, and the first railing 22 is slidably connected to the sliding groove 211; one end of the support leg 30 is hinged to the end of the bottom rod 12 away from the base 11, and the other end is hinged to the end of the first railing 22 away from the connecting member 21; the limiting structure 40 includes a first limiting member 41 and a second limiting member 42, the first limiting member 41 is arranged on one of the connecting member 21 and the first railing 22, and the second limiting member 42 is arranged on the other of the connecting member 21 and the first railing 22; the baby cot has an unfolded form and a folded form, and during the process of the baby cot switching between the unfolded form and the folded form, the first limiting member 41 and the second limiting member 42 are configured to be clamped and matched with each other so that the baby cot is in a temporarily fixed form.
[0045] When the baby cot is in the temporarily fixed form, through the clamping cooperation between the first limiting member 41 and the second limiting member 42, the relative position between the connecting member 21 and the first railing 22 is restricted, that is, the connecting member 21 and the first railing 22 are relatively stationary, which can keep the railing group 20 stable during the process of the baby cot form switching, avoid excessive inclination of the top of the support leg 30 during the form switching process, reduce the operation difficulty of the baby cot form switching, and is beneficial to the improvement of the user experience.
[0046] When there is no limiting structure 40 for limiting, when the baby cot switches forms, the base 11 is directly moved downward, and the first railing 22 will move relative to the connecting member 21, making the top of the baby cot unstable and the railing group 20 having a large degree of freedom, making the support leg 30 prone to inclination, and the baby cot cannot be smoothly unfolded, increasing the unfolding difficulty of the baby cot.
[0047] When preparing to unfold the baby cot, move the connecting member 21 upward until the first limiting member 41 and the second limiting member 42 are clamped and matched to realize the restriction of the relative position between the first railing 22 and the connecting member 21, ensure the stability of the top of the baby cot (the top of the support leg 30), and then move the base 11 downward. The base 11 drives the bottom rod 12 to push the bottom of the support leg 30 outward (in the direction away from the connecting member 21, the same below). At this time, the baby cot is close to the unfolded form. Release the clamping state between the first limiting member 41 and the second limiting member 42, 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 railing 22 moves relative to the connecting member 21 until the baby cot is in the unfolded form.
[0048] 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 bottom rod 12 and the first surrounding rod 22 respectively through the connecting sleeves, which can protect the ends of the support leg 30, the bottom rod 12 and the first surrounding rod 22 and prevent users from being injured.
[0049] In some embodiments, the surrounding rod group 20 further includes a second surrounding rod 23. When the children's bed is in the unfolded state, the second surrounding rod 23 is arranged at the bottom of the first surrounding rod 22, and one end of the second surrounding rod 23 is hinged to the support leg 30 and the other end is hinged to the connecting member 21. By providing the second surrounding rod 23, it can be ensured that when the children's bed is unfolded, the first surrounding rod 22 can smoothly enter the limiting groove section 2111.
[0050] Refer to Figure 10 and Figure 11 , in some embodiments, the first limiting member 41 and the second limiting member 42 can be the settings of a clamping pin 53 (the first limiting member 41) and a clamping hole 54 (the second limiting member 42). The clamping pin 53 is arranged on the first surrounding rod 22 through a spring 51, the clamping hole 54 is arranged on the connecting member 21, and the clamping pin 53 has an inclined surface 531, and the inclined surface 531 is slidably connected to the hole wall of the clamping hole 54.
[0051] During use, first move the connecting member 21 upward, the first surrounding rod 22 rotates relative to the connecting member 21, the clamping pin 53 contacts the side wall of the connecting member 21, the spring 51 is compressed, and the clamping pin 53 is retracted by the side wall of the connecting member 21. Continue to rotate the first surrounding rod 22, and the clamping pin 53 moves to be opposite to the clamping hole 54. Under the action of the spring 51, the clamping pin 53 is clamped in the clamping hole 54, realizing the restriction between the connecting member 21 and the first surrounding rod 22; during the subsequent form switching process, as the support leg 30 moves outward, the first surrounding rod 22 rotates relative to the connecting member 21, and the clamping pin 53 moves out of the clamping hole 54 (that is, the clamping state between the first limiting member 41 and the first limiting member 41 is released), and the unlocking of the clamping state between the first limiting member 41 and the second limiting member 42 can be realized without manual intervention.
[0052] When the children's bed is in the unfolded state, the clamping pin 53 is pressed against the side wall of the connecting member 21 under the action of the spring 51, increasing the static friction force between the connecting member 21 and the clamping pin 53 (as shown in Figure 8 and Figure 9 ), which is beneficial to the stability of the relative position between the first surrounding rod 22 and the connecting member 21, that is, beneficial to maintaining the stability of the unfolded state of the children's bed; and during the switching process of the children's bed from the temporarily fixed state to the unfolded state, the clamping pin 53 is always pressed against the side wall of the connecting member 21, which is beneficial to the stability of the children's bed during the form switching process.
[0053] It should be noted that the clamping pin 53 is installed and fixed through the mounting member 52 provided inside the first surrounding rod 22. There is a mounting hole on the mounting member 52, and the spring 51 and the clamping pin 53 are arranged in the mounting hole. The mounting hole can limit the deformation amount of the spring 51 in the upward direction of the mounting hole diameter within a certain range (determined by the diameter size of the mounting hole), which is beneficial to the stability of the clamping pin 53, and further realizes the stability of the temporary fixed form of the children's bed (the clamping pin 53 is stably inserted into the clamping hole 54). In addition, the inclined surface 531 of the clamping pin 53 can facilitate the movement of the clamping pin 53 in the direction towards the spring 51 when the clamping pin 53 contacts the connecting member 21, and the clamping pin 53 can automatically enter and exit the clamping hole 54 during the process of form switching; the inclined surface 531 can be in the shape of a conical surface, a spherical surface, etc.
[0054] In some embodiments, the cooperation between the clamping pin 53 and the clamping hole 54 may not be automatically switched; for example Figure 12 as shown, the clamping pin 53 does not have an inclined surface 531 and is a cylindrical surface (or Figure 12 the horizontal plane in the perspective view, etc.). When it is necessary to release the temporary fixed form of the children's bed, it is necessary to manually intervene to move the clamping pin 53 to the left so that the clamping pin 53 exits the clamping hole 54.
[0055] Refer to Figure 3 and Figure 4 When the children's bed is in the unfolded form, the first surrounding rods 22 on both sides of the connecting member 21 are horizontally arranged; when the children's bed is in the temporary fixed form, the first surrounding rods 22 on both sides of the connecting member 21 are in a Λ shape.
[0056] When the first limiting member 41 and the second limiting member 42 are clamped and connected, that is, when the children's bed is in the temporary fixed form, the first surrounding rods 22 on both sides of the connecting member 21 are in a Λ shape, and when the relative position between the first surrounding rod 22 and the connecting member 21 is restricted, the connecting member 21 is located above the children's bed (as Figure 3 shown). During the process of the children's bed switching from the temporary fixed form to the unfolded form, the connecting member 21 moves downward until the first surrounding rod 22 is horizontally arranged; when the children's bed needs to be folded, the connecting member 21 directly moves downward, and the first surrounding rods 22 on both sides of the connecting member 21 rotate relative to the connecting member 21. During the folding process of the children's bed, the first surrounding rod 22 and the connecting member 21 will not pass through the restricted state (that is, the state where the first surrounding rods 22 on both sides of the connecting member 21 are in a Λ shape). That is, during the folding process of the children's bed, the first limiting member 41 and the second limiting member 42 will not restrict the first surrounding rod 22 and the connecting member 21, and the children's bed can be folded smoothly and quickly.
[0057] It should be noted that, in the present embodiment, when the first enclosure rod 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 enclosure rods 22 on both sides of the connecting member 21 can also be arranged at an angle (not an angle of 180°), and the two first enclosure rods 22 are not parallel, but are not limited to this.
[0058] In some embodiments, when the child bed is in the unfolded state, the first surrounding bars 22 on both sides of the connecting member 21 are arranged horizontally; when the child bed is in the temporarily fixed state, the first surrounding bars 22 on both sides of the connecting member 21 are V-shaped, such as Figure 13 As shown ( Figure 13 Only the schematic diagram related to the fence group 20 is given).
[0059] When the child's bed is in a temporarily fixed form, the first surrounding rods 22 on both sides of the connecting piece 21 are V-shaped. In the process of switching the child's bed from the temporarily fixed form to the unfolded form, the connecting piece 21 moves upward until the first surrounding rods 22 on both sides of the connecting piece 21 are horizontally arranged. With this arrangement, the connecting piece 21 does not need to be lifted above the child's bed, and can improve the stability of the top of the child's bed during the unfolding process, and can also improve the stability of the child's bed during the folding process.
[0060] When the child bed starts to fold from the unfolded state, the connecting piece 21 moves downward, the horizontally arranged first surrounding rod 22 rotates into a V shape, the first limit piece 41 and the second limit piece 42 cooperate to engage, and then the base 11 is pulled upward, the bottom of the supporting leg 30 is folded inward through the bottom rod 12, and then the direct engagement state between the first limit piece 41 and the second limit piece 42 is released, and the connecting piece 21 continues to move downward until the child bed is in the folded state; the stability of the surrounding rod group 20 during the folding process of the child bed is improved, and the instability of the top of the child bed during the folding process is avoided.
[0061] See also Figures 4 - 6 The sliding groove 211 has a second guide groove section 2113 and a first guide groove section 2112 which are arranged in sequence from top to bottom and connected to each other. The groove walls connected to 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 child bed is in a folded form, the connecting pin of the first surrounding rod 22 is slidably connected to the first guide groove section 2112; when the child bed is in a temporarily fixed form, the first surrounding rod 22 is connected to the second guide groove section 2113.
[0062] By setting the groove walls of the first guide groove section 2112 and the second guide groove section 2113 at an angle, the difficulty of the first surrounding rod 22 sliding from the first guide groove section 2112 to the second guide groove section 2113 is increased, that is, the first surrounding rod 22 is not easy to slide from the first guide groove section 2112 into the second guide groove section 2113.
[0063] During the actual unfolding operation of the child bed, there may be misoperation or people may not know how to unfold the child bed, and the base 11 may be moved downward directly. As the base 11 moves, the first enclosure rod 22 slides from the first guide groove section 2112 toward the second guide groove section 2113. When sliding to the connection between the first guide groove section 2112 and the second guide groove section 2113 (the connecting pin of the first enclosure rod 22 slides to the connection between the first guide groove section 2112 and the second guide groove section 2113), the sliding is restricted because the groove wall connecting the first guide groove section 2112 and the second guide groove section 2113 is set at an angle, and the first enclosure rod 22 is The connecting pin of the first surrounding rod 22 cannot smoothly enter the second guide groove section 2113, that is, the base 11 cannot continue to move downward to perform the operation of unfolding the child bed; at this time, the first limit member 41 and the second limit member 42 have not reached the matching position. If the base 11 continues to move downward, the top of the child bed will continue to expand outward and it is easy to shake; the groove wall connected by the first guide groove section 2112 and the second guide groove section 2113 is set at an angle, which limits the connection pin of the first surrounding rod 22 from continuing to move, thereby avoiding the shaking of the top of the child bed (the supporting leg 30 is tilted) due to misoperation, which is not conducive to improving the user experience.
[0064] In this embodiment, it is necessary to move the connecting member 21 upward until the first limit member 41 and the second limit member 42 are engaged and engaged, so that the first surrounding rod 22 and the connecting member 21 are temporarily fixed, and then the base 11 is moved downward to realize the unfolding operation of the child bed; in this embodiment, before moving the connecting member 21 upward to the child bed in a temporarily fixed state, the base 11 can be moved downward first until the connecting pin of the first surrounding rod 22 is stuck at the connection between the first guide groove section 2112 and the second guide groove section 2113. At this time, the support leg 30 of the child bed will have a certain displacement to the surroundings, which provides operating space for moving the connecting member 21 upward, facilitates the operation of moving the connecting member 21 upward, and after the support leg 30 has a certain displacement to the surroundings, the angle between the two first surrounding rods 22 in the same surrounding rod group 20 becomes larger, and it is more labor-saving to move the connecting member 21 upward; the subsequent unfolding operation of the child bed will not be repeated here.
[0065] It should be noted that the connecting pin of the first enclosure rod 22 is used for the first enclosure rod 22 to slide in the sliding groove 211, which is not marked in the figure.
[0066] In some embodiments, the sliding groove 211 also has a limiting groove section 2111, and the second guide groove section 2113 is arranged between the first guide groove section 2112 and the sliding groove 211; when the children's bed is in the unfolded form, the connecting pin of the first surrounding rod 22 is clamped in the limiting groove section 2111.
[0067] Through the provision of the limit groove section 2111, the stability of the children's bed in the unfolded state can be ensured. During the process of the children's bed switching from the temporarily fixed state to the unfolded state, the connecting pin of the first railing 22 can automatically slide from the second guiding groove section 2113 into the limit groove section 2111 and be clamped in the limit groove section 2111, achieving the stability of the children's bed in the unfolded state without additional structures.
[0068] In some embodiments, the length of the first guiding groove section 2112 is substantially equal to the length of the second guiding groove section 2113.
[0069] When the children's bed is in the folded state, the connecting pin of the first railing 22 is slidably connected to the first guiding groove section 2112. When the children's bed is in the unfolded state, the connecting pin of the first railing 22 is slidably connected in the limit groove section 2111; when the connecting pin of the first railing 22 is at the connection of the first guiding groove section 2112 and the second guiding groove section 2113, and since the length of the first guiding groove section 2112 is substantially equal to the length of the second guiding groove section 2113, the children's bed is in a semi-unfolded state between the folded state and the unfolded state; when the children's bed is in the semi-unfolded state, the distance between the support legs 30 is not far, the children's bed has a certain stability. At the same time, it also provides sufficient operating space for moving the connecting member 21 upward. Moreover, when the children's bed is in the semi-unfolded state, the first railings 22 on both sides of the connecting member 21 are more likely to rotate relative to the connecting member 21, reducing the labor intensity when moving the connecting member 21 upward.
[0070] When the length of the first guiding groove section 2112 is less than the length of the second guiding groove section 2113, and the connecting pin of the first railing 22 is clamped between the first guiding groove section 2112 and the second guiding groove section 2113, the children's bed is in a state between the folded state and the semi-unfolded state. The ends of the first railings 22 on both sides of the connecting member 21 that are far from the connecting member 21 are relatively close (the included angle between the first railings 22 on both sides of the connecting member 21 is small), which will increase the difficulty of moving the connecting member 21 upward; when the length of the first guiding groove section 2112 is greater than the length of the second guiding groove section 2113, and the first railing 22 is clamped between the first guiding groove section 2112 and the second guiding groove section 2113, the children's bed is in a state between the semi-unfolded state and the unfolded state. The top of the children's bed has a large unfolding range, and the top of the children's bed is unstable, which is not conducive to the unfolding operation of the children's bed.
[0071] It should be noted that in this embodiment, for the unfolding operation of the children's bed, first move the base 11 downward until the connecting pin of the first railing 22 is clamped between the first guiding groove section 2112 and the second guiding groove section 2113, then move the connecting member 21 upward until the first limiting member 41 and the second limiting member 42 are cooperatively clamped, and finally move the base 11 downward again to complete the unfolding of the children's bed.
[0072] In addition, the length of the first guiding groove section 2112 is substantially equal to that of the second guiding groove section 2113, or the length of the first guiding groove section 2112 may be slightly greater or slightly less than that of the second guiding groove section 2113.
[0073] See Figure 2 , when the children's bed is in the folded state, the first guardrails 22 on both sides of the connecting member 21 are in a V shape.
[0074] The first guardrails 22 on both sides of the connecting member 21 are in a V shape, that is, the distance between the two first guardrails 22 is set to be wider at the top and narrower at the bottom. The wider setting at the top provides an operating space for moving the connecting member 21 upward, facilitating the operation of the user; at the same time, the V-shaped setting is beneficial to the first guardrail 22 rotating away from the connecting member 21 when the connecting member 21 is moved upward (the first guardrails 22 on both sides of the connecting member 21 rotate outward), reducing the labor intensity when the connecting member 21 is moved upward.
[0075] In some embodiments, there are four sets of guardrail groups 20, and the oppositely arranged guardrail groups 20 are provided with limiting structures 40.
[0076] By providing the limiting structures 40 on the oppositely arranged guardrail groups 20, when the first guardrail 22 and the connecting member 21 are limited by the first limiting member 41 and the second limiting member 42, the force on both sides of the children's bed can be ensured to be uniform, which is beneficial 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 members 21 on both sides of the children's bed at the same time, which is beneficial to the smooth unfolding of the children's bed.
[0077] In some embodiments, in the guardrail group 20 provided with the limiting structure 40, the length of the first guardrail 22 is the first length; in the guardrail group 20 not provided with the limiting structure 40, the length of the first guardrail 22 is the second length; the first length is less than the second length.
[0078] The limiting structure 40 is arranged on the shorter first guardrail 22. When the children's bed is in the folded state, the position of the connecting member 21 connected to the shorter first guardrail 22 is higher and is more easily touched by the operator during the unfolding operation of the children's bed, while the connecting member 21 on the longer first guardrail 22 is not easily touched. Such a setting is beneficial to the unfolding operation of the children's bed; at the same time, when the children's bed is switched from the folded state to the temporarily fixed state, it is necessary to move the connecting member 21 upward. During the upward movement of the connecting member 21, the first guardrail 22 will push the support legs 30 outward. The longer first guardrail 22 will push the support legs 30 outward to a farther distance. When the limiting structure 40 is arranged on the first guardrail 22 with a longer length, the support legs 30 need to move a greater distance to realize the switching of the children's bed from the folded state to the temporarily fixed state.
[0079] On the other hand, the present 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; The connecting member 21 provided with the limiting structure 40 is driven to move upward. While the connecting member 21 moves upward, it pushes the first surrounding rod 22 to move the top of the support leg 30 away from the connecting member 21; Until the first limiting member 41 and the second limiting member 42 are engaged and clamped, and the tops of adjacent support legs 30 are temporarily fixed, the children's bed is in a temporarily fixed state; The base 11 is driven to move downward, and drives the bottom rod 12 to move the bottom of the support leg 30 away from the side of the base 11, and the bottom frame assembly 10 is expanded, and the clamping cooperation between the first limiting member 41 and the second limiting member 42 is released; The base 11 is driven to continue to move downward until the children's bed is in an unfolded state.
[0080] When the children's bed is in a temporarily fixed state, the relative position between the connecting member 21 and the first surrounding rod 22 is restricted by the clamping cooperation between the first limiting member 41 and the second limiting member 42, that is, the connecting member 21 and the first surrounding rod 22 are relatively stationary. During the process of the children's bed changing its form, the stability of the surrounding rod group 20 can be maintained, the top of the support leg 30 is prevented from tilting excessively during the form switching process, the operation difficulty of the children's bed form switching is reduced, and the user experience is improved.
[0081] When there is no limit structure 40 for limiting, when the children's bed changes its form, the base 11 is directly moved downward, and the first surrounding rod 22 will move relative to the connecting member 21, making the top of the children's bed unstable, and the surrounding rod group 20 has a large degree of freedom, making the support leg 30 prone to tilting, and the children's bed cannot be unfolded smoothly, increasing the unfolding difficulty of the children's bed.
[0082] In some embodiments, the cooperation and clamping of the first limiting member 41 and the second limiting member 42 include: The clamping pin 53 moves into the clamping hole 54; Releasing the clamping cooperation between the first limiting member 41 and the second limiting member 42 includes: The base 11 is driven to continue to move downward, the bottom of the support leg 30 continues to move away from the side of the base 11, the top of the support leg 30 drives the first surrounding rod 22 to move relative to the connecting member 21, the inclined surface 531 of the clamping pin 53 slides with the hole wall of the clamping hole 54, and exits from the clamping hole 54.
[0083] The inclined surface 531 of the clamping pin 53 can facilitate the movement of the clamping pin 53 when it comes into contact with the connecting member 21 and is squeezed. During the process of form switching, the clamping pin 53 can automatically enter and exit the clamping hole 54; The inclined surface 531 can be in the shape of a conical surface, a spherical surface, etc.
[0084] In some embodiments, the base 11 is driven to continue moving downward, the bottom of the support leg 30 continues to move away from the side of the base 11, and the top of the support leg 30 drives the first surrounding rod 22 to move relative to the connecting member 21, including: the support leg 30 rotates relative to the second surrounding rod 23, and the top of the support leg 30 drives the first surrounding rod 22 to move toward the direction close to the connecting member 21.
[0085] It should be noted that when the crib is in the unfolded state, the second surrounding rod 23 is arranged at the bottom of the first surrounding rod 22, and one end of the second surrounding rod 23 is hinged to the support leg 30 and the other end is hinged to the connecting member 21. Through the arrangement of the second surrounding rod 23, it can be ensured that when the crib is unfolded, the first surrounding rod 22 can smoothly enter the limiting groove section 2111.
[0086] In some embodiments, before driving the connecting member 21 provided with the limiting structure 40 to move upward, it further includes: driving the base 11 to move downward, and driving the bottom rod 12 to move the bottom of the support leg 30 away from the side of the base 11. The top of the support leg 30 drives the first surrounding rod 22 to move relative to the connecting member 21, so that the connecting pin of the first surrounding rod 22 slides in cooperation with the first guiding groove section 2112 until the connecting pin of the first surrounding rod 22 is clamped at the connection between the first guiding groove section 2112 and the second guiding groove section 2113; driving the connecting member 21 to move upward. While the connecting member 21 moves upward, it pushes the first surrounding rod 22 to move the top of the support leg 30 away from the connecting member 21, and the connecting pin of the first surrounding rod 22 slides toward the second guiding groove section 2113, thereby releasing the clamping of the connecting pin of the first surrounding rod 22 at the connection between the first guiding groove section 2112 and the second guiding groove section 2113.
[0087] During the actual unfolding operation of the child bed, there may be misoperation or people may not know how to unfold the child bed, and the base 11 may be moved downward directly. As the base 11 moves, the first enclosure rod 22 slides from the first guide groove section 2112 toward the second guide groove section 2113. When sliding to the connection between the first guide groove section 2112 and the second guide groove section 2113 (the connecting pin of the first enclosure rod 22 slides to the connection between the first guide groove section 2112 and the second guide groove section 2113), the sliding is restricted because the groove wall connecting the first guide groove section 2112 and the second guide groove section 2113 is set at an angle, and the first enclosure rod 22 is The connecting pin of the first surrounding rod 22 cannot smoothly enter the second guide groove section 2113, that is, the base 11 cannot continue to move downward to perform the operation of unfolding the child bed; at this time, the first limit member 41 and the second limit member 42 have not reached the matching position. If the base 11 continues to move downward, the top of the child bed will continue to expand outward and it is easy to shake; the groove wall connected by the first guide groove section 2112 and the second guide groove section 2113 is set at an angle, which limits the connection pin of the first surrounding rod 22 from continuing to move, thereby avoiding the shaking of the top of the child bed (the supporting leg 30 is tilted) due to misoperation, which is not conducive to improving the user experience.
[0088] In this embodiment, before moving the connecting piece 21 upward to the temporary fixed form of the children's bed, the base 11 can be moved downward first until the connecting pin of the first surrounding rod 22 is stuck at the connection between the first guide groove section 2112 and the second guide groove section 2113. At this time, the support leg 30 of the children's bed will have a certain displacement in all directions, which provides operating space for moving the connecting piece 21 upward, facilitates the operation of moving the connecting piece 21 upward, and after the support leg 30 has a certain displacement in all directions, the angle between the two first surrounding rods 22 in the same surrounding rod group 20 becomes larger, and it is more labor-saving to move the connecting piece 21 upward; the subsequent unfolding operation of the children's bed will not be repeated here.
[0089] It should be noted that, in some embodiments, before the aforementioned unfolding step of the child bed, the base 11 needs to be unlocked, and the base 11 includes an upper support and a lower support which are socketed with each other, which will not be described in detail here.
[0090] The technical solution provided in the embodiment of the present application is intended to limit the relative position between the connecting member 21 and the first surrounding rod 22 by the snap-fitting cooperation between the first limiting member 41 and the second limiting member 42, that is, the connecting member 21 and the first surrounding rod 22 are relatively stationary, which can maintain the stability of the surrounding rod group 20 during the switching of the shape of the child bed, avoid excessive tilting of the top of the supporting leg 30 during the shape switching process, reduce the operational difficulty of switching the shape of the child bed, and is conducive to improving the user experience.
