[0037] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0038] In the description of this application, it should be noted that, unless otherwise clearly specified 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 mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] The fence assembly, the children's bed and the method for unfolding the children's bed in the present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] In the prior art, during the unfolding process, the fence has a high degree of freedom, that is, the top of the supporting leg is unstable and easily tilted, which increases the difficulty of unfolding the child bed.

[0041] In order to solve the above technical problems, the embodiment of the present application provides a fence assembly, which is applied to a children's bed, and the fence assembly includes a connecting member, a connecting rod and a limiting structure; the connecting member is provided with a sliding groove; the connecting rod is slidably connected to the sliding groove; the limiting structure includes a first limiting member and a second limiting member, the first limiting member is arranged at one of the connecting member and the connecting rod, and the second limiting member is arranged at the other of the connecting member and the connecting rod; the children's bed has an expanded form and a folded form, and during the process of switching between the expanded form and the folded form, 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. The following is a detailed description.

[0042] See also Figure 1-4 The surrounding rod assembly 20 includes a connecting member 21, a connecting rod 22 and a limiting structure 40; the connecting member 21 is provided with a sliding groove 211; the connecting rod 22 is slidably connected to the sliding groove 211; the limiting structure 40 includes a first limiting member 41 and a second limiting member 42, the first limiting member 41 is arranged at one of the connecting member 21 and the connecting rod 22, and the second limiting member 42 is arranged at the other of the connecting member 21 and the connecting rod 22; the child bed has an expanded form and a folded form. During the switching process of the child bed between the expanded form and the folded form, the first limiting member 41 and the second limiting member 42 are configured to be engaged with each other so that the child bed is in a temporarily fixed form.

[0043] When the child's bed is in a temporarily fixed form, the relative position between the connecting member 21 and the connecting rod 22 is limited by the snap-fit ​​cooperation between the first limiting member 41 and the second limiting member 42, that is, the connecting member 21 and the connecting rod 22 are relatively stationary, which can maintain the stability of the surrounding rod assembly 20 during the form switching process of the child's bed, avoid excessive tilting of the top of the supporting leg 30 during the form switching process, reduce the difficulty of operating the child's bed form switching, and is conducive to improving the user experience.

[0044] When there is no limiting structure 40, the connecting rod 22 will move relative to the connecting piece 21 during the unfolding operation of the child bed, making the top of the child bed unstable, the surrounding rod assembly 20 has a large degree of freedom, the supporting legs 30 of the child bed are easy to tilt, and the child bed cannot be unfolded smoothly, which increases the difficulty of unfolding the child bed and provides a poor user experience.

[0045] In this embodiment, when preparing to unfold the child's bed, first rotate the connecting rod 22 (the connecting member 21 moves upward) to a preset position (the child's bed is in a temporarily fixed form, the same below). At this time, the top of the child's bed is in an open state, and the relative displacement between the connecting rod 22 and the connecting member 21 is limited by the limiting structure 40, and the surrounding rod assembly 20 connected to the top of the supporting leg 30 is in a stable state, that is, the top of the supporting leg 30 can ensure a stable state; then move the base frame assembly 10 (including the base 11 and the bottom rod 12 hinged to the base 11) downward, and the bottom of the supporting leg 30 is stretched away from the base 11 under the action of the bottom rod 12. At this time, the child's bed is close to the unfolded form, and the limiting state of the limiting structure 40 on the connecting rod 22 and the connecting member 21 is released (the clamping state between the first limiting member 41 and the second limiting member 42 is released), and the base frame assembly 10 continues to move downward until the child's bed is in the unfolded form.

[0046] It should be noted that after the connecting rod 22 is rotated to the preset position, the position is limited by the limiting structure 40. The preset position here can be that the connecting rod 22 is rotated to a horizontal state in some embodiments. At this time, the surrounding rod assembly 20 is fully unfolded, and the base frame assembly 10 is moved downward to achieve the full unfolding of the children's bed.

[0047] In some embodiments, the temporary fixed form can also be that the connecting rod 22 rotates to a non-horizontal state (not reaching the horizontal state or continuing to rotate beyond the horizontal state after reaching the horizontal state); for example, when the child bed is in the unfolded form, the connecting rod 22 is in a horizontal state, and when the child bed is in the temporary fixed form, the connecting rods 22 on both sides of the connecting member 21 are arranged in a Λ shape, that is, after the connecting rod 22 rotates to the preset position, the relative position between the connecting member 21 and the connecting rod 22 is limited, and the connecting member 21 is located above the child bed; in the process of folding the child bed, the connecting member 21 moves directly downward from the horizontal state (the connecting rods 22 on both sides of the connecting member 21 are in a horizontal state), and the connecting rod 22 and the connecting member 21 will not pass through the restricted state (that is, the connecting rods 22 on both sides of the connecting member 21 are in a Λ shape), that is, in the process of folding the child bed, the first limit member 41 and the second limit member 42 will not cause restrictions between the connecting rod 22 and the connecting member 21, and the child bed can be folded smoothly and quickly.

[0048] In this embodiment, when the connecting rod 22 rotates to a horizontal state, the surrounding rod assembly 20 is unfolded, that is, the child bed is fully unfolded; in some embodiments, the connecting rod 22 may also be in a non-horizontal state when the child bed is fully unfolded, and relevant designs are made according to the specific structure of the child bed, etc., but are not limited to this.

[0049] In some embodiments, the limiting structure 40 temporarily fixes the connecting rod 22 and the connecting member 21 not only when the child bed is unfolded, but also when the child bed is in the folded form. When the child bed is in the folded form, the limiting structure 40 limits the relative rotation between the connecting rod 22 and the connecting member 21, thereby ensuring the stability of the folded form of the child bed.

[0050] In some embodiments, the temporary fixing effect of the limiting structure 40 on the connecting rod 22 and the connecting member 21 can also be in the process of folding the child bed; for example, when the child bed is in the unfolded state, the connecting rods 22 on both sides of the connecting member 21 are arranged horizontally; when the child bed is in the temporary fixed state, the connecting rods 22 on both sides of the connecting member 21 are V-shaped, such as Fig. 9 As shown ( Fig. 9 Only the schematic diagram related to the fence assembly 20 is given).

[0051] When the child bed is in a temporarily fixed form, the connecting rods 22 on both sides of the connecting piece 21 are V-shaped. In the process of switching the child bed from the temporarily fixed form to the unfolded form, the connecting piece 21 moves upward until the connecting 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 bed, and can improve the stability of the top of the child bed during the unfolding process, and can also improve the stability of the child bed during the folding process.

[0052] When the child bed starts to fold from the unfolded state, the connecting piece 21 moves downward, the horizontally arranged connecting 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.

[0053] In some embodiments, the surrounding rod assembly 20 further includes an auxiliary rod 23 to ensure the stability of the surrounding rod assembly 20 when it is unfolded.

[0054] When the child bed is in the unfolded form, the auxiliary rod 23 is arranged at the bottom of the connecting rod 22, and one end of the auxiliary rod 23 is hinged on the supporting leg 30, and the other end is hinged on the connecting member 21. Through the setting of the auxiliary rod 23, it can be ensured that when the child bed is unfolded, the connecting rod 22 can smoothly enter the groove section used for limiting in the sliding groove 211.

[0055] See also Figure 3 , Figure 5 and Fig. 9 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 the folded form, the connecting pin of the connecting rod 22 is slidably connected to the first guide groove section 2112; when the child bed is in the temporarily fixed form, the connecting rod 22 is connected to the second guide groove section 2113.

[0056] The groove walls of the first guide groove section 2112 and the second guide groove section 2113 are arranged at an angle, which increases the difficulty of the connecting rod 22 sliding from the first guide groove section 2112 to the second guide groove section 2113, that is, the connecting rod 22 is not easy to slide from the first guide groove section 2112 to the second guide groove section 2113.

[0057] During the actual unfolding operation of the child bed, there may be cases of misoperation or not knowing how to unfold the child bed, and the base 11 may be moved downward directly. As the base 11 moves, the connecting 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 connecting 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 connecting rod 2 2 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 and engaging position. If the base 11 continues to move downward, the top of the child bed will continue to expand outward, which is prone to shaking; 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 connecting rod 22 from continuing to move, thereby avoiding shaking of the top of the child bed (tilting of the support leg 30) due to misoperation, which is not conducive to improving the user experience.

[0058] 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 connecting 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 connecting 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 connecting 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.

[0059] It should be noted that the connecting pin of the connecting rod 22 is used for the connecting rod 22 to slide in the sliding groove 211, which is not marked in the figure.

[0060] 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 connecting rod 22 is clamped in the limiting groove section 2111.

[0061] By setting the limiting groove section 2111, the stability of the child bed in the expanded form can be ensured. During the process of switching the child bed from the temporary fixed form to the expanded form, the connecting pin of the connecting rod 22 can autonomously slide from the second guide groove section 2113 into the limiting groove section 2111 and be clamped in the limiting groove section 2111. The stability of the child bed in the expanded form can be achieved without the need for additional structure.

[0062] In some embodiments, the length of the first guide slot segment 2112 is substantially equal to the length of the second guide slot segment 2113 .

[0063] When the child bed is in the folded form, the connecting pin of the connecting rod 22 slides in the first guide groove section 2112, and when the child bed is in the expanded form, the connecting pin of the connecting rod 22 slides in the limiting groove section 2111; when the connecting pin of the connecting rod 22 is at the connection between the first guide groove section 2112 and the second guide groove section 2113, and because the length of the first guide groove section 2112 is substantially equal to the length of the second guide groove section 2113, the child bed is in a semi-expanded form between the folded form and the expanded form; when the child bed is in the semi-expanded form, the mutual distance between the supporting legs 30 is not far, the child bed has a certain stability, and at the same time, it also provides sufficient operating space for moving the connecting member 21 upward, and when the child bed is in the semi-expanded form, the connecting rods 22 on both sides of the connecting member 21 are easier to rotate relative to the connecting member 21, thereby reducing the labor intensity when the connecting member 21 is moved upward.

[0064] When the length of the first guide groove section 2112 is less than the length of the second guide groove section 2113, and the connecting pin of the connecting rod 22 is clamped between the first guide groove section 2112 and the second guide groove section 2113, the child bed is in a state between the folded state and the semi-expanded state, and the connecting rods 22 on both sides of the connecting member 21 are closer to the ends away from the connecting member 21 (the angle between the connecting rods 22 on both sides of the connecting member 21 is smaller), which will increase the difficulty of moving the connecting member 21 upward; when the length of the first guide groove section 2112 is greater than the length of the second guide groove section 2113, and the connecting rod 22 is clamped between the first guide groove section 2112 and the second guide groove section 2113, the child bed is in a state between the semi-expanded state and the expanded state, the top of the child bed has a larger expansion range, the top of the child bed is unstable, and it is not conducive to the expansion operation of the child bed.

[0065] It should be noted that, in the present embodiment, the unfolding operation of the children's bed is to first move the base 11 downward until the connecting pin of the connecting rod 22 is engaged between the first guide groove section 2112 and the second guide groove section 2113, and then move the connecting member 21 upward until the first limit member 41 and the second limit member 42 are engaged and engaged, and finally move the base 11 downward to achieve full unfolding of the children's bed.

[0066] In addition, the length of the first guide groove segment 2112 is substantially equal to the length of the second guide groove segment 2113 , and the length of the first guide groove segment 2112 may be slightly greater than or slightly less than the length of the second guide groove segment 2113 .

[0067] See also Figure 5 and Figure 6 The first limiting member 41 is a clamping block 50, the second limiting member 42 is a clamping hole 60, the clamping block 50 is arranged on the connecting rod 22 through an adjusting structure 70, and the clamping hole 60 is arranged on the connecting member 21; the adjusting structure 70 is configured to adjust the radial position of the clamping block 50 on the connecting rod 22; when the child bed is in a temporarily fixed form, the clamping block 50 is clamped in the clamping hole 60.

[0068] In this embodiment, the relative position between the connecting member 21 and the connecting rod 22 is limited by the engagement between the engaging block 50 and the engaging hole 60 , so that the surrounding rod assembly 20 can be kept stable during the unfolding of the child bed.

[0069] When in use, first move the connecting piece 21 upward, the connecting rod 22 rotates relative to the connecting piece 21, the clamping block 50 contacts the side wall of the connecting piece 21, and the clamping block 50 moves along the radial direction of the connecting rod 22 toward the side away from the clamping hole 60 under the adjustment of the adjustment structure 70, and the connecting rod 22 continues to be rotated. The clamping block 50 moves with the connecting rod 22 to be arranged opposite to the clamping hole 60. Under the action of the adjustment structure 70, the clamping block 50 is clamped in the clamping hole 60 to complete the restriction of the relative position between the connecting rod 22 and the connecting piece 21; in the subsequent unfolding process, the clamping block 50 is moved out of the clamping hole 60, and the restriction between the connecting piece 21 and the connecting rod 22 is released until the surrounding rod assembly 20 (children's bed) is fully unfolded.

[0070] It should be noted that, in some embodiments, the clamping block 50 may also move along other directions, not limited to the radial direction of the connecting rod 22 .

[0071] In some embodiments, when the child bed is in the unfolded state, the clamping block 50 is pressed against the side wall of the connecting member 21 facing the clamping block 50 .

[0072] When the child bed is in the unfolded state, the clamping block 50 is pressed against the side wall of the connecting member 21, thereby increasing the static friction between the clamping block 50 and the side wall of the connecting member 21 (such as Figure 5 As shown in the figure, it is beneficial to stabilize the relative position between the connecting rod 22 and the connecting member 21, that is, it is beneficial to maintain the stability of the unfolded form of the child bed, and in the process of switching the child bed from the temporary fixed form to the unfolded form, the clamping block 50 is always pressed against the side wall of the connecting member 21, which is beneficial to the stability of the child bed during the form switching process.

[0073] See also Figure 6-8The adjustment structure 70 includes a compression spring 71 and a through hole 72 ; the through hole 72 is disposed on the peripheral wall of the connecting rod 22 , and the clamping block 50 is connected to the inside of the connecting rod 22 through the compression spring 71 and passes through the through hole 72 .

[0074] The end of the clamping block 50 is placed on the outside of the connecting rod 22 by the compression spring 71. During the rotation of the connecting rod 22 relative to the connecting member 21, the clamping block 50 abuts against the side wall of the connecting member 21, so that the compression spring 71 is compressed by force, and the clamping block 50 moves along the radial direction of the connecting rod 22. The connecting rod 22 continues to rotate until the clamping block 50 is opposite to the clamping hole 60. Under the action of the compression spring 71, the clamping block 50 is reset and clamped in the clamping hole 60, thereby limiting the relative position between the connecting member 21 and the connecting rod 22. The structure is simple and easy to use. It can realize the switching of the states (locked state and unlocked state) between the connecting rod 22 and the connecting member 21, which is beneficial to the unfolding operation of the children's bed.

[0075] In some embodiments, the clamping block 50 includes a connected limiting portion 52 and a clamping portion 53, and the clamping portion 53 is inserted into the through hole 72; the cross-sectional area of ​​the clamping portion 53 is smaller than the cross-sectional area of ​​the connecting portion 51, so as to form a contact surface 54 at the connection between the clamping portion 53 and the connecting portion 51; the contact surface 54 abuts against the inner circumferential wall of the connecting rod 22.

[0076] By setting the abutment surface 54 to abut against the inner wall of the connecting rod 22, the compression spring 71 is prevented from having excessive pressure so that the clamping block 50 is ejected from the through hole 72, which is beneficial to the stable installation of the clamping block 50 on the connecting rod 22, and further beneficial to the stability of the connecting piece 21 and the connecting rod 22 when they are in a locked state.

[0077] In some embodiments, the clamping block 50 also includes a connecting portion 51, and a limiting portion 52 is arranged between the connecting portion 51 and the clamping portion 53; the cross-sectional area of ​​the connecting portion 51 is smaller than the cross-sectional area of ​​the limiting portion 52, so as to form a mounting surface 55 at the connection between the connecting portion 51 and the limiting portion 52; the compression spring 71 is sleeved on the connecting portion 51 and crimped on the mounting surface 55.

[0078] The arrangement of the connecting portion 51 is conducive to the stable installation of the compression spring 71 , and the force exerted by the compression spring 71 on the clamping block 50 is also relatively stable, which is conducive to the stability of the connecting member 21 and the connecting rod 22 in the locked state.

[0079] In some embodiments, the outer peripheral wall of the engaging portion of the engaging portion 53 and the engaging hole 60 is tapered, so that the engaging block 50 can smoothly enter and exit the engaging hole 60 without manual intervention, thereby ensuring the smoothness of the unfolding operation of the child bed.

[0080] The adjustment structure 70 also includes a mounting block 73 , which is disposed inside the connecting rod 22 and has a mounting hole 731 , to which the clamping block 50 is connected; the outer diameter of the compression spring 71 is substantially equal to the diameter of the mounting hole 731 .

[0081] By setting the size of the mounting hole 731, it can be ensured that the compression spring 71 moves axially along the mounting hole 731 when subjected to compression, thereby reducing the radial displacement of the compression spring 71 in the mounting hole 731, which is beneficial to the stability of the force applied by the compression spring 71 to the clamping block 50, and further beneficial to the stability of the connecting member 21 and the connecting rod 22 when in a locked state.

[0082] It should be noted that the outer diameter of the compression spring 71 is substantially equal to the diameter of the mounting hole 731 , that is, the outer diameter of the compression spring 71 is slightly smaller than the diameter of the mounting hole 731 . To ensure that the compression spring 71 can be smoothly installed into the mounting hole 731 , a certain amount of assembly margin needs to be reserved.

[0083] In the axial direction of the connecting rod 22 , one end of the mounting block 73 is provided with a weakened countersunk hole 732 .

[0084] When the mounting block 73 is installed inside the connecting rod 22, the end of the mounting block 73 provided with the weakened countersunk hole 732 can produce a slight deformation, so that the mounting block 73 can be smoothly installed into the connecting rod 22, reducing the difficulty of installation.

[0085] In some embodiments, a plurality of mounting grooves 733 are provided at intervals on the outer peripheral wall of the mounting block 73, which separates the outer peripheral wall opposite to the mounting block 73 and the connecting rod 22 into multiple parts, thereby reducing the friction between the mounting block 73 and the inner peripheral wall of the connecting rod 22 and facilitating the smooth installation of the mounting block 73.

[0086] In some embodiments, the mounting block 73 is fixed to the connecting rod 22 by a pin, and the axial direction of the pin is perpendicular to the moving direction of the snap-in block 50 (the axial direction of the mounting hole 731). When installing the mounting block 73 and the snap-in block 50, the relative position of the snap-in block 50 can be determined by the pin to ensure that the snap-in block 50 can pass through the through hole 72.

[0087] In some embodiments, four groups of the surrounding rod assemblies 20 are provided, and the relatively arranged surrounding rod assemblies 20 are provided with limiting structures 40.

[0088] A limiting structure 40 is provided by relatively arranging the surrounding rod assembly 20. When the connecting 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 child bed is uniform, which is beneficial to the stability of the child bed during the unfolding process; and during the unfolding process of the child bed, it can be convenient for the operator to operate the connecting members 21 on both sides of the child bed at the same time, which is beneficial to the smooth unfolding of the child bed.

[0089] In some embodiments, in the enclosure rod assembly 20 provided with a limiting structure 40, the length of the connecting rod 22 is a first length; in the enclosure rod assembly 20 not provided with a limiting structure 40, the length of the connecting rod 22 is a second length; the first length is less than the second length.

[0090] The limiting structure 40 is arranged on the shorter connecting rod 22. When the child bed is in the folded form, the connecting piece 21 connected to the shorter connecting rod 22 is located higher and is easier to be touched by the operator when the child bed is unfolded. The connecting piece 21 on the longer connecting rod 22 is not easy to be touched. Such a setting is conducive to the unfolding operation of the child bed. At the same time, in the process of switching the child bed from the folded form to the temporarily fixed form, the connecting piece 21 needs to be moved upward. In the process of the connecting piece 21 moving upward, the connecting rod 22 will push the support leg 30 outward. The longer connecting rod 22 will push the support leg 30 outward a farther distance. When the limiting structure 40 is arranged on the longer connecting rod 22, the support leg 30 needs to move a greater distance to realize the switching of the child bed from the folded form to the temporarily fixed form.

[0091] On the other hand, the present application also relates to a children's bed, comprising any of the aforementioned guardrail assemblies 20, the children's bed also comprising a base assembly 10 and support legs 30, the base assembly 10 comprising a base 11 and a bottom rod 12 spaced apart on the periphery of the base 11, the bottom rod 12 being hinged to the base 11; 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 connecting rod 22 away from the connecting member 21.

[0092] On the other hand, the present application also relates to a method for unfolding a child's bed, comprising the following steps: the child's bed is in a folded form; the connecting member 21 provided with a limiting structure 40 is driven to move upward, and while the connecting member 21 moves upward, the connecting rod 22 is pushed to move the top of the supporting leg 30 in a direction away from the connecting member 21; until the first limiting member 41 and the second limiting member 42 are engaged and snap-fitted, and the tops of adjacent supporting legs 30 are temporarily fixed, the child's bed is in a temporarily fixed form; the base 11 is driven to move downward, and drives the bottom rod 12 to move the bottom of the supporting leg 30 to the side away from the base 11, the base frame assembly 10 is stretched open, and the snap-fitting 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 child's bed is in an unfolded form.

[0093] When the child's bed is in a temporarily fixed form, the relative position between the connecting member 21 and the connecting rod 22 is limited by the snap-fit ​​cooperation between the first limiting member 41 and the second limiting member 42, that is, the connecting member 21 and the connecting rod 22 are relatively stationary, which can maintain the stability of the surrounding rod assembly 20 during the form switching process of the child's bed, avoid excessive tilting of the top of the supporting leg 30 during the form switching process, reduce the difficulty of operating the child's bed form switching, and is conducive to improving the user experience.

[0094] When there is no limiting structure 40, the connecting rod 22 will move relative to the connecting piece 21 during the unfolding operation of the child bed, making the top of the child bed unstable, the surrounding rod assembly 20 has a large degree of freedom, the supporting legs 30 of the child bed are easy to tilt, and the child bed cannot be unfolded smoothly, which increases the difficulty of unfolding the child bed and provides a poor user experience.

[0095] In some embodiments, the first limit member 41 and the second limit member 42 are engaged and snap-fitted, including: the snap-fit ​​block 50 moves into the snap-fit ​​hole 60; the snap-fitting between the first limit member 41 and the second limit member 42 is released, including: the base 11 is driven to continue to move downward, the bottom of the support leg 30 continues to move toward the side away from the base 11, the top of the support leg 30 drives the connecting rod 22 to move relative to the connecting member 21, the inclined surface of the snap-fit ​​portion 53 slides with the hole wall of the snap-fit ​​hole 60, and exits from the snap-fit ​​hole 60.

[0096] The clamping portion 53 has an inclined surface, which can facilitate the clamping block 50 (the inclined surface of the clamping portion 53) to move under compression when the clamping block 50 contacts the connecting piece 21, and can automatically realize the clamping block 50 entering and exiting the clamping hole 60 during the form switching process; the inclined surface can be a conical surface, a spherical surface, etc.

[0097] In some embodiments, the base 11 is driven to continue moving downward, the bottom of the support leg 30 continues to move toward the side away from the base 11, and the top of the support leg 30 drives the connecting rod 22 to move relative to the connecting member 21, including: the support leg 30 rotates relative to the auxiliary rod 23, and the top of the support leg 30 drives the connecting rod 22 to move toward the direction close to the connecting member 21.

[0098] It should be noted that when the child's bed is in the unfolded form, the auxiliary rod 23 is arranged at the bottom of the connecting rod 22, and one end of the auxiliary rod 23 is hinged on the supporting leg 30, and the other end is hinged on the connecting member 21. Through the setting of the auxiliary rod 23, it can be ensured that when the child's bed is unfolded, the connecting rod 22 can smoothly enter the groove section used for limiting in the sliding groove 211.

[0099] In some embodiments, before driving the connecting member 21 provided with a limiting structure 40 to move upward, it also includes: driving the base 11 to move downward, and driving the bottom rod 12 to move the bottom of the supporting leg 30 toward the side away from the base 11, and the top of the supporting leg 30 drives the connecting rod 22 to move relative to the connecting member 21, so that the connecting pin of the connecting rod 22 cooperates with and slides in the first guide groove section 2112 until the connecting pin of the connecting rod 22 is engaged with the connection between the first guide groove section 2112 and the second guide groove section 2113; driving the connecting member 21 to move upward, and while the connecting member 21 moves upward, it pushes the connecting rod 22 to move the top of the supporting leg 30 away from the connecting member 21, and the connecting pin of the connecting rod 22 slides toward the second guide groove section 2113, thereby releasing the engagement of the connecting pin of the connecting rod 22 at the connection between the first guide groove section 2112 and the second guide groove section 2113.

[0100] During the actual unfolding operation of the child bed, there may be cases of misoperation or not knowing how to unfold the child bed, and the base 11 may be moved downward directly. As the base 11 moves, the connecting 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 connecting 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 connecting rod 2 2 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 and engaging position. If the base 11 continues to move downward, the top of the child bed will continue to expand outward, which is prone to shaking; 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 connecting rod 22 from continuing to move, thereby avoiding shaking of the top of the child bed (tilting of the support leg 30) due to misoperation, which is not conducive to improving the user experience.

[0101] 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 connecting 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 connecting rods 22 in the same surrounding rod group 20 becomes larger, which saves more effort when moving the connecting piece 21 upward; the subsequent unfolding operation of the children's bed will not be repeated here.

[0102] 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.

[0103] 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 connecting 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 connecting rod 22 are relatively stationary, which can maintain the stability of the surrounding rod assembly 20 during the process of switching 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.
