Description

Technical Field

[0001] This application relates to the field of baby product technology, and more specifically, to a crib. Background Technology

[0002] Foldable cribs, playpens, and children's beds are widely used due to their ease of storage and transportation. The frames of these products are typically made up of multiple rods connected by pivoting joints (such as hinges and universal joints). The relative rotation of the rods and joints allows the product to switch between an unfolded, usable state and a folded, stored state.

[0003] To create enclosures or sleeping areas, frames are typically fitted with drapes made of flexible materials such as fabric or mesh. These drapes are usually threaded onto the poles or fixed to specific parts of the frame. However, when the product is folded, a large opening forms at the connection between the pivot joint and the pole, causing the drape threaded onto the pole to accumulate there due to gravity. During subsequent unfolding, this opening gradually closes as the frame expands, easily crushing or tearing the accumulated drape. Therefore, an improved solution is urgently needed to address the problem of drape damage during folding and transitioning. Utility Model Content

[0004] In view of the above problems, this application provides a crib to solve the above problems.

[0005] In a first aspect, this application provides a crib, including a carrying space, one side of which has an opening, and the crib further includes: A frame structure, comprising at least two connectors, at least two blocking members, multiple connecting rods, and multiple connecting parts; Each blocking element is located within a connecting element; The connecting part is located between adjacent connecting rods to form an opening; At least two links each include two members. In each link, one of the at least two connectors is pivotally connected to the pivot ends of the two members respectively, and the movable ends of the two members are connected to different connection parts respectively. The blocking element is located between the connector and the two rods, and is partially exposed outside the connector; When the crib is folded up, the connector moves in the opposite direction to the opening, and the connecting parts that are connected to the movable ends of the two rods move towards each other and come together. The seat fabric is fitted onto the frame structure.

[0006] In some embodiments, the connector includes a connecting body and a pivot, wherein the pivotal ends of the connecting body and the rod are pivotally connected via the pivot; In this context, along the first direction and within the same projection plane, the projection of the pivot and the projection of the connecting body both fall within the projection of the blocking member, and the first direction is parallel to the recessed direction of the opening of the bearing space.

[0007] In some embodiments, the connecting body has a shielding space, which is recessed along one side of the bottom wall of the connecting body toward the bearing space; The pivot end of the rod is provided with a pivot through hole that runs radially through the rod, and the pivot is inserted through the pivot through hole. At least a portion of the area from the pivot through hole to the end face of the pivot end of both rods is located within the shielding space.

[0008] In some embodiments, the pivot points between the two rods in each link and the connector are the first pivot point and the second pivot point, respectively. The blocking member includes a first blocking portion, which is provided between the first pivot and the seat fabric in a direction away from the bottom wall of the bearing space; and / or, the blocking member includes a second blocking portion, which is provided between the second pivot and the seat fabric in a direction away from the bottom wall of the bearing space.

[0009] In some embodiments, the blocking member includes a first blocking portion, a second blocking portion, and an elastic portion. The first blocking portion and the second blocking portion are connected by the elastic portion. The blocking member is configured such that when the crib is in a folded state and the two rods press against the blocking member, the first blocking portion and the second blocking portion move toward each other.

[0010] In some embodiments, the connector is provided with an extension groove extending along the extension direction of the rod, and the blocking member is slidably connected to the extension groove; in a first preset position, along a first direction, the projection of the pivot point of the connector and the pivot end of the blocking member is located within the projection of the blocking member; in a second preset position, along the first direction, the projection of the pivot point and the projection of the blocking member are spaced apart, and the first direction is parallel to the recessed direction of the opening of the bearing space.

[0011] In some embodiments, the edge of the blocking member along the extension direction of the rod is an arc-shaped edge.

[0012] In some embodiments, the frame structure further includes a locking component disposed on the connector, the locking component being configured to selectively lock or release the pivot connection between the rod and the connector.

[0013] In some embodiments, the connecting body includes two first parts and a second part. The two first parts are arranged opposite to each other along a second direction. The two first parts are connected to each other along the side away from the bottom wall of the bearing space through the second part. The two first parts and the second part enclose a shielding space. The recessed direction of the opening of the bearing space, the parallel arrangement direction of the two rods in the connecting rod, and the second direction intersect each other. A locking component is inserted through the first part, and a pivot end of a rod is provided between the locking component and the second part along the first direction.

[0014] In some embodiments, the locking component includes: The first locking member and the second locking member each include a connecting push part and a locking part. Along the first direction, the push part is disposed on the side of the locking part facing away from the second part. The push parts of the first locking member and the second locking member are disposed opposite to each other along the extension direction of the two rods. In the locked state, the locking part abuts against the end face of the pivot end of the rod. The first direction is parallel to the recessed direction of the opening of the bearing space. The pusher is configured such that, when pressed, it pushes the pusher portion of the first locking member and the pusher portion of the second locking member to move in opposite directions, so that the locking portion separates from the end face of the pivot end of the rod. An elastic element that connects the locking part of the first locking element and the locking part of the second locking element.

[0015] In the crib provided in this application, when the crib is in the folded state, the connector moves in the opposite direction to the opening, and a large opening is formed at the connection between the connector and the rod (i.e., the pivot joint). The seat fabric stacks towards the pivot joint due to gravity. The part of the blocking member exposed outside the connector supports the stacked seat fabric and prevents the seat fabric from stacking into the opening, thereby reducing the possibility that the seat fabric stacked at the connector will be crushed or torn during subsequent unfolding, improving the service life of the crib, reducing the frequency of seat fabric replacement, and reducing the user's maintenance costs.

[0026] In this application, "multiple" means two or more (including two).

[0027] Please refer to the following: Figures 1 to 3 According to some embodiments of this application, a crib is provided, which includes a carrying space E. One side of the carrying space E has an opening K. The crib also includes a frame structure 100 and a seat cover 200. The frame structure 100 includes at least two connectors 10, at least two blocking members 20, multiple connecting rods, and multiple connecting portions 50. Each blocking member 20 is disposed within a connector 10. The connecting portions 50 are disposed between adjacent connecting rods to form the opening K. Each of the at least two connecting rods includes two members 30. Within each connecting rod, one of the at least two connectors 10 is pivotally connected to the pivot ends of the two members 30, and the movable ends 30c of the two members 30 are respectively connected to different connecting portions 50. The blocking members 20 are located between the connector 10 and the two members 30, and are partially exposed outside the connector 10. When the crib is folded, the connector 10 moves in the opposite direction to the opening K, and the connecting part 50, which is connected to the movable end 30c of the two rods 30, moves towards each other and closes. The seat cover 200 is fitted onto the frame structure 100.

[0028] The crib may include a frame structure 100, a seat cover 200, and other components, such as the seat cover 200 supported by the frame structure 100, a mattress on the seat cover 200, parts for connecting and securing the crib covers and the frame structure 100, etc. Optionally, the crib may have wheels at the bottom of the frame structure 100 for easy movement; for example, wheels may be provided in multiple areas at the bottom of the frame structure; or, as... Figure 1 As shown, wheels are provided in a portion of the bottom area of ​​the frame structure 100, and a fixed seat is provided in another portion. When movement is required, the fixed seat can be tilted up to allow the wheels to move the crib. When the crib is fixed, the wheels can be fixed by a braking structure or the like, so that the wheels and the fixed seat together support the crib and restrict its movement. As another embodiment, the crib can also be used only in a fixed position, as shown in the crib frame structure 100 in Figure 2, where the bottom of the frame structure 100 only has a fixed seat.

[0029] It should be noted that this application is based on Figure 2 The frame structure 100 shown is used as an example for illustration.

[0030] In some examples, the frame structure 100 can have a usable state. The usable state is the state in which the crib is used normally. Of course, the frame structure 100 can also have a folded state, which is for the convenience of transporting or storing the crib. The folded state can have a much smaller volume than the usable state. The process of changing from the usable state to the folded state is called the folded state, and the process of changing from the folded state to the usable state is called the unfolded state.

[0031] The frame structure 100 may include handrail assemblies, column assemblies, and a bottom assembly. The handrail assemblies are connected to the bottom assembly via the column assemblies. The handrail assemblies enclose an opening K in the load-bearing space E. The bottom assembly encloses the bottom of the load-bearing space E and provides support for the entire frame structure 100. Optionally, the handrail assembly may include connecting rods. Optionally, the column assembly and the handrail assembly may be fixedly connected or pivotally connected. Optionally, the column assembly and the bottom assembly may be fixedly connected or pivotally connected.

[0032] For example, the load-bearing space E is a rectangular space with an opening K (first opening) on ​​one side. The connecting rod includes multiple first connecting rods 1 located at the upper part of the frame structure 100 (first opening), which are connected end-to-end by connecting parts 50 to form the rectangular opening K. The connecting rod also includes multiple second connecting rods 2 located at the bottom of the frame structure 100 (away from the first opening), which are connected by connectors 10 to form a rectangular bottom. The connecting rod also includes multiple third connecting rods 3 connecting the first connecting rods 1 and the second connecting rods 2. The multiple third connecting rods 3 connect at least the four corners of the rectangular opening K and the rectangular bottom. It can be understood that the rectangular bottom can be a rectangle formed by multiple second connecting rods 2 connected end-to-end by connecting parts 50, or it can be an "X" shape formed by multiple second connecting rods 2 connected by connecting parts 50, with the four ends of the "X" shape being the four corners of the rectangular bottom. Furthermore, the rectangular bottom can also have transverse connecting rods (or longitudinal connecting rods) added to the "X" shaped frame to further enhance the support performance of the bottom.

[0033] The first link 1 and the third link 3 can be connected by a connecting part 50. Optionally, the first link 1 and the third link 3 can also be pivotally connected by the connecting part 50 so that the first link 1 and the third link 3 can rotate relative to each other.

[0034] The second link 2 and the third link 3 can be connected by a connecting part 50. Optionally, the second link 2 and the third link 3 can also be pivotally connected by the connecting part 50, so that the second link 2 and the third link 3 can rotate relative to each other.

[0035] Multiple first links 1 can be connected to each other via connecting parts 50. Optionally, one side edge of the rectangular opening K can be formed by a first link 1, and two rods 30 within the first link 1 are pivotally connected by a connector 10, so that the edge of the rectangular opening K can be folded.

[0036] Optionally, the first opening K includes two first edges opposite each other along the length of the rectangle. Each first edge can be formed by a first link 1; in other words, two rods 30 within a first link 1 together form the first edge.

[0037] For example, when the connecting rod forms the first edge, the two first edges can rotate around the pivot point P of the pivot end of the connector 10 and the rod 30 as the pivot point, so that the first edge can be unfolded and folded, so that the crib can be switched between the use state and the folded state.

[0038] Optionally, the first opening K includes two opposing second edges along the width direction of the rectangle. Each second edge can be formed by a first link 1; in other words, two members 30 within a first link 1 together form the second edge.

[0039] For example, when the linkage forms the second edge, the two second edges can rotate around the pivot point P of the pivot end of the connector 10 and the rod 30 as the pivot point, so that the second edge can be unfolded and folded, thereby allowing the crib to switch between the use state and the folded state.

[0040] Within each link, at least one of the two connectors 10 is pivotally connected to the pivot end 30a of each of the two links 30. In other words, the two links 30 can rotate about the pivot point P with the connector 10 as the fulcrum, so that the movable ends 30c of the two links move closer to each other (folded state) or further apart (use state). Here, "pivot" refers to the connection method in which the pivot end 30a of the link 30 rotates around an axis or a point. Here, "pivot point P" refers to the position where the link 30 and the connector 10 are connected together.

[0041] The movable ends 30c of the two rods 30 are respectively connected to different connecting parts 50. In other words, the movable end 30c of one of the two rods 30 is connected to one connecting part 50, and the rod 30 can pivot relative to the connecting part 50; the movable end 30c of the other rod 30 is connected to another connecting part 50, and the rod 30 can pivot relative to the other connecting part 50.

[0042] Each blocking element 20 is disposed within a connecting element 10, that is, a blocking element 20 is disposed within a connecting element 10.

[0043] The blocking member 20 is located between the connector 10 and the two rods 30, and is partially exposed outside the connector 10. In other words, the pivot ends 30a of the connector and the rods 30 are arranged side by side along the first direction X, and at least a portion of the pivot ends 30a of the rods 30 is located on the side of the connector 10 facing the bottom wall of the bearing space E. Along the first direction X, the blocking member 20 is located between the connector 10 and the pivot ends 30a of the two rods 30, and a portion of the blocking member 20 is exposed outside the connector 10. The portion of the blocking member 20 exposed outside the connector 10 can be referred to as the shielding portion. The shielding portion extends from the blocking member 20 along the extension direction of the rods 30, and the projection of the shielding portion in the first direction X covers at least a portion of the projection of the pivot ends 30a of the rods 30 along the first direction X. The first direction X is parallel to the recessed direction of the opening K of the bearing space E.

[0044] When the crib is in the folded state, the connector 10 moves in the opposite direction to the opening K (i.e., the concave direction of the opening K), and the connecting portion 50 connected to the movable ends 30c of the two rods 30 moves towards each other and closes. Exemplarily, one rod forms one edge of the opening K, two adjacent rods form two adjacent edges of the opening K, and one of the two connecting portions 50 connected to the movable ends 30c of the two rods 30 is a corner of the two adjacent edges. When the connector 10 moves in the opposite direction to the opening K, it moves closer to the bottom wall of the bearing space E, and the two corners of this edge move closer together, causing the edge to fold with the middle as the folding point. This causes the two third connecting rods connected to the two corners of this edge to move closer together, forming multiple edges of the opening K. Repeating the same action can reduce the overall volume of the frame structure.

[0045] When the crib is folded, the connector 10 moves in the opposite direction to the opening K (i.e., in the concave direction of the opening K); when the crib is unfolded, the connector 10 moves in the forward direction of the opening K. Therefore, the connector 10 can reciprocate along the first direction X. When the connector 10 reciprocates along the first direction X, the blocking member 20 reciprocates along with the connector 10.

[0046] Optionally, the blocking member 20 can be fixedly connected to the connecting member 10. Of course, the blocking member 20 can also be movably connected to the connecting member 10. When the connecting member 10 moves along the first direction X, the blocking member 20 moves with the connecting member 10.

[0047] Optionally, the blocking member 20 can be a plate-shaped structural member.

[0048] The seat cover 200 is used to form a barrier to reduce the risk of an infant or items within the carrying space E falling out of the carrying space E. The seat cover 200 may be installed only on the side wall of the carrying space E. The seat cover 200 may also consist of two parts, one part installed on the side wall of the carrying space E and the other part installed on the bottom wall of the carrying space E.

[0049] Optionally, the seat cover 200 may include a shielding body and a shielding connecting part. The shielding body is disposed on the side wall of the bearing space E, and the shielding connecting part is connected to the linkage assembly. Optionally, the shielding connecting part may enclose a connecting space, in which the linkage, connector 10, and blocking member 20 pass through. Optionally, the shielding connecting part may also cover one side of the linkage assembly along the first direction X.

[0050] In the above embodiment, the connector 10 and the blocking member 20 can move up and down along the first direction X. The blocking member 20 can be disposed on the upper side of the pivot end 30a of the rod 30, that is, the blocking member 20 is disposed on the side of the pivot end 30a of the rod 30 away from the bottom wall of the bearing space E.

[0051] The pivot point P of the pivot end 30a of the connector 10 and the rod 30 includes a first side and a second side opposite to each other along a first direction X. The first side is the side facing away from the bottom wall of the bearing space E, and the second side is the side facing the bottom wall of the bearing space E. It is understood that the seat fabric 200 is sleeved on the frame structure, and the first side of the pivot point P has the seat fabric 200, and the second side of the pivot point P also has the seat fabric 200. The blocking member 20 is only provided between the first side of the pivot point P and the seat fabric 200. When the crib is folded, the connector 10 moves in the opposite direction to the opening K, and a large opening is formed at the connection between the connector 10 and the rod 30 (i.e., the pivot point P). The seat cloth 200 stacks towards the pivot point P due to gravity. The part of the blocking member 20 exposed outside the connector 10 supports the stacked seat cloth 200 and prevents the seat cloth 200 from stacking into the opening. This reduces the possibility that the seat cloth 200 stacked at the connector 10 will be crushed or torn during subsequent unfolding, improves the service life of the crib, reduces the frequency of seat cloth 200 replacement, and reduces the user's maintenance costs.

[0052] In some alternative embodiments, please refer to Figure 1 and Figure 4 The connector 10 includes a connecting body 11 and a pivot 12. The connecting body 11 and the pivot end 30a of the rod 30 are pivotally connected via the pivot 12. Along the first direction X and within the same projection plane, the projections of the pivot 12 and the connecting body 11 both fall within the projection of the blocking member 20. The first direction X is parallel to the recessed direction of the opening K of the bearing space E.

[0053] Optionally, such as Figure 3 and Figure 4As shown, the connecting body 11 has two connecting holes 13, and a pivot end 30a of the rod 30 is provided between the two connecting holes 13. A pivot 12 passes through the two connecting holes 13 and the pivot end 30a of the rod 30 located between the two connecting holes 13, connecting the connecting body 11 and the rod 30. The rod 30 can rotate about the pivot 12 as the fulcrum.

[0054] Along the first direction X and within the same projection plane, the projections of the pivot 12 and the connecting body 11 both fall within the projection of the blocking member 20. In other words, the projection plane perpendicular to the first direction X is the first projection plane, and the orthographic projection of the pivot 12 in the first projection plane falls within the orthographic projection of the blocking member 20 in the first projection plane, and the orthographic projection of the connecting body 11 in the first projection plane also falls within the orthographic projection of the blocking member 20 in the first projection plane. Here, "falling within the orthographic projection of the blocking member 20 in the first projection plane" means that the orthographic projection area of ​​the blocking member 20 in the first projection plane is larger than the orthographic projection area of ​​the pivot 12 (and / or the connecting body 11) in the first projection plane, and the outline of the orthographic projection of the pivot 12 (and / or the connecting body 11) in the first projection plane is located within the orthographic projection of the blocking member 20 in the first projection plane.

[0055] In these embodiments, since the connecting body 11 is pivotally connected to the pivot ends 30a of the two rods 30, the blocking member 20 needs to block the two pivot points P. With the above arrangement, it is advantageous to block the two pivot points P with one blocking member 20, thereby simplifying the overall structure of the blocking member 20 and reducing the manufacturing cost of the blocking member 20.

[0056] In some alternative embodiments, please refer to Figure 4 and Figure 5 The connecting body 11 is provided with a shielding space 111, which is recessed along the bottom wall of the connecting body 11 facing the bearing space E. The pivot end 30a of the rod 30 is provided with a pivot through hole 30b that extends radially through the rod 30. The pivot 12 passes through the pivot through hole 30b. At least a portion of the area from the pivot through hole 30b of the two rods 30 to the end face of the pivot end 30a is provided within the shielding space 111.

[0057] like Figure 4 and Figure 5As shown, the pivot end 30a is provided with a pivot through hole 30b. The pivot 12 passes through the pivot through hole 30b and is connected to the connecting body 11. The pivot through hole 30b is formed by penetrating the pivot end 30a radially along the rod 30. There is a certain distance between the end faces of the pivot through hole 30b and the pivot end 30a (that is, the structure between the end faces of the pivot through hole 30b and the pivot end 30a is called the pivot end 30a). The pivot end 30a and other parts of the rod 30 along their own extension direction rotate around the pivot 12 as the rotation fulcrum. The movement direction of the pivot end 30a along the first direction X (such as moving towards the bottom wall of the bearing space E) is opposite to the movement direction of other parts of the rod 30 along its own extension direction (such as the movable end 30c) along the first direction X (such as moving away from the bottom wall of the bearing space E).

[0058] The two adjacent pivot ends 30a refer to the pivot ends 30a of the two rods 30 that are pivotally connected to a connector 10. The two pivot ends 30a are set in the shielding space 111. The connecting body 11 forming the shielding space 111 is located between the seat cloth 200 and the pivot ends 30a, which reduces the possibility of the pivot ends 30a directly contacting the seat cloth 200 during rotation, causing the seat cloth 200 to be punctured, and improves the service life of the crib.

[0059] Optionally, the blocking member 20 is provided with a first mounting hole 24, and the blocking member 20 can be connected to the connecting member 10 by a fixed mounting structure. Further, the connecting member 10 is provided with a second mounting hole 15 that matches the first mounting hole 24; the fixed mounting structure (such as a rivet) passes through the second mounting hole 15 and the first mounting hole 24 in sequence to connect the blocking member 20 to the connecting member 10.

[0060] In some alternative embodiments, such as Figure 6 As shown, the pivot points P between the two rods 30 in each connecting rod and the connector 10 are the first pivot point and the second pivot point, respectively. The blocking member 20 includes a first blocking part 21, which is provided between the first pivot point and the seat fabric 200 along the direction away from the bottom wall of the bearing space E; and / or, the blocking member 20 includes a second blocking part 22, which is provided between the second pivot point and the seat fabric 200 along the direction away from the bottom wall of the bearing space E.

[0061] In some examples, the blocking member 20 includes a first blocking portion 21, which is provided between the first pivot and the seat fabric 200 along the direction away from the bottom wall of the bearing space E. Furthermore, the blocking member 20 includes a second blocking portion 22, which is provided between the second pivot and the seat fabric 200 along the direction away from the bottom wall of the bearing space E. In other examples, the blocking member 20 includes a first blocking portion 21, which is provided between the first pivot and the seat fabric 200 along the direction away from the bottom wall of the bearing space E. In still other examples, the blocking member 20 includes a second blocking portion 22, which is provided between the second pivot and the seat fabric 200 along the direction away from the bottom wall of the bearing space E.

[0062] In some examples, continue to refer to Figure 5 The first blocking part 21 and the second blocking part 22 can be an integral structure, that is, the first blocking part 21 and the second blocking part 22 are connected. In other examples, continue to refer to Figure 6 The first blocking part 21 and the second blocking part 22 are separate structures, and the first blocking part 21 and the second blocking part 22 are respectively connected to the connector 10.

[0063] In the above embodiment, the first blocking part 21 is disposed between the first side of the first pivot and the seat cloth 200, and the second blocking part 22 is disposed between the first side of the second pivot and the seat cloth 200. The two blocking parts can respectively prevent the seat cloth 200 from stacking towards the two pivots P. The two blocking parts can be designed independently according to the size of the pivot P, thereby improving the design flexibility of the blocking member 20 and increasing the applicability of the blocking member 20.

[0064] In some alternative embodiments, reference continues to be made to Figure 6 As shown, the blocking member includes a first blocking part, a second blocking part, and an elastic part. The first blocking part 21 and the second blocking part 22 are connected by the elastic part 23. The blocking member 20 is configured such that when the crib is in the folded state and the two rods 30 press against the blocking member 20, the first blocking part 21 and the second blocking part 22 move toward each other.

[0065] Optionally, the elastic part 23 may include a spring, rubber, bellows, magnetic repulsion mechanism, etc.

[0066] When the stroller is folded, the areas of the two rods 30 near the pivot end 30a approach each other. As the degree of folding increases, the exposed portions of the rods 30 and the blocking members 20 outside the connector 10 come into contact, and the two rods 30 press against the blocking members 20. At this time, the first blocking part 21 and the second blocking part 22 move towards each other, thereby further reducing the overall size after folding and ensuring that the first blocking part 21 and the second blocking part 22 respectively cover the openings of the two pivot points P. This reduces the possibility that the stacked seat cloth 200 will be crushed or torn during subsequent unfolding, improves the service life of the stroller, reduces the frequency of seat cloth replacement, and reduces the user's maintenance costs.

[0067] When the stroller is in the unfolded state, the pressure exerted by the rod 30 on the blocking member 20 gradually decreases, and the elastic potential energy of the elastic part 23 decreases, so that the first blocking part 21 and the second blocking part 22 move in opposite directions, increasing the blocking area of ​​the first blocking part 21 and the second blocking part 22, reducing the possibility of the stacked seat cloth 200 falling into the opening during the unfolding process, and improving the reliability of the blocking member 20.

[0068] In some alternative embodiments, such as Figure 7 As shown, the connector 10 has an extension groove 14 extending along the extension direction of the rod 30, and the blocking member 20 is slidably connected to the extension groove 14. In a first preset position, along the first direction X, the projection of the pivot point P between the connector 10 and the pivot end 30a is located within the projection of the blocking member 20. In a second preset position, along the first direction X, the projections of the pivot point P and the blocking member 20 are spaced apart. The first direction X is parallel to the recessed direction of the opening K of the bearing space E. Optionally, the extension direction of the rod 30 can be the extension direction of the rod 30 in the use state.

[0069] Optionally, the blocking member 20 may be provided with a slider, which is slidably connected to the extension groove 14.

[0070] For example, the first blocking part 21 is provided with a first slider on the side facing the connector 10, and the first slider is slidably connected to the extension groove 14. The first blocking part 21 can move along the extension direction of the extension groove 14 so that the blocking member 20 switches between a first preset position and a second preset position.

[0071] For example, the second blocking part 22 is provided with a second slider on the side facing the connector 10, and the second slider is slidably connected to the extension groove 14. The second blocking part 22 can move along the extension direction of the extension groove 14 to switch the blocking member 20 between a first preset position and a second preset position.

[0072] In the first preset position, along the first direction X, the projection of the pivot P is located within the projection of the blocking member 20. That is, when the blocking member 20 slides to the first preset position, it can be used to fold the two rods 30, thereby blocking the enlarged opening and reducing the possibility of the seat cloth 200 being stacked into the opening. In the second preset position, along the first direction X, the projection of the pivot P and the projection of the blocking member 20 are set at an interval. That is, when the blocking member 20 slides to the second preset position, it can be used to expose the pivot P, so as to facilitate cleaning of the pivot P and disassembly and replacement, thus improving the maintainability of the crib.

[0073] The projection of the pivot point P and the projection of the blocking member 20 along the first direction X are spaced apart. This means that the projection of the pivot point P along the first direction X and the projection of the blocking member 20 along the first direction X are spaced apart. That is, along the direction away from the bottom wall of the bearing space E, the line connecting the pivot point P and the seat cloth 200 is staggered with the blocking member 20.

[0074] Optionally, the second preset position can be the area between two pivot points P in a connector 10, that is, the entire blocking member 20 is located within the connector 10. For example, when the blocking member 20 is in the second preset position, the projection of the first blocking portion 21 along the first direction X is located in the gap between the projections of the first pivot point along the first direction X and the projections of the second pivot point along the first direction X. The projection of the second blocking portion 22 along the first direction X is located in the gap between the projections of the first pivot point along the first direction X and the projections of the second pivot point along the first direction X.

[0075] In some alternative embodiments, please continue to refer to Figure 7 The edge of the blocking member 20 along the extension direction of the rod 30 is an arc-shaped edge.

[0076] For example, the edge of the blocking member 20 along the extension direction of the rod 30 refers to the extension direction of the edge formed by the linkage assembly in the use state.

[0077] The edge of the blocking member 20 along the extension direction of the rod 30 is an arc-shaped edge, for example, the edge of the blocking member 20 along the extension direction of the rod 30 is a rounded arc edge.

[0078] In these alternative embodiments, the above-described configuration effectively reduces the risk of the edge of the blocking member 20 puncturing the seat fabric 200, while its smooth edge transition (such as chamfering or rounding) also avoids accidental scratching with the user's skin, thereby significantly improving the overall safety and user experience of the crib.

[0079] In some alternative embodiments, please continue to refer to Figure 4 and Figure 6The frame structure 100 also includes a locking component 40 disposed on the connector 10, and the locking component 40 is configured to selectively lock or release the pivotal connection between the rod 30 and the connector 10.

[0080] For example, when the crib is in use, the locking assembly 40 can lock the pivotal connection between the rod 30 and the connector 10 so that the rod 30 and the connector 10 are fixed at the pivot 12 and cannot rotate, thereby improving the rigidity and stability of the frame structure 100 in use.

[0081] For example, when the crib is in the folded or unfolded state, the locking assembly 40 can release the pivotal connection between the rod 30 and the connector 10, so that the rotational constraint between the rod 30 and the connector 10 is contacted, restoring the normal rotation of the pivot 12, thereby allowing for smooth folding or unfolding.

[0082] In the above embodiments, by setting the locking component 40, it is beneficial to reduce the possibility of the frame structure 100 being folded due to accidental external forces and improve the active safety of the frame structure 100.

[0083] In some alternative embodiments, please refer to Figure 7 and Figure 8 The connecting body 11 includes two first parts 112 and a second part 113. The two first parts 112 are arranged opposite each other along the second direction Y. The two first parts 112 are connected by the second part 113 along the side away from the bottom wall of the bearing space E. The two first parts 112 and the second part 113 enclose a shielding space 111. The recessed direction of the opening K of the bearing space E, the side-by-side arrangement direction of the two rods 30 in the connecting rod, and the second direction Y intersect each other. The locking component 40 passes through the first part 112. Along the first direction X, a pivot end 30a of the rod 30 is provided between the locking component 40 and the second part 113.

[0084] For example, the connecting body 11 can be a U-shaped groove structure. The two first parts 112 can be upright plates on both sides, and the second part 113 is a bottom plate connecting the upright plates on both sides. The shielding space 111 is a U-shaped groove space formed by the two upright plates and the bottom plate. The opening K of the U-shaped groove faces the bottom wall of the bearing space E.

[0085] The concave direction of the opening K of the bearing space E, the side-by-side arrangement direction of the two rods 30 within the connecting rod, and the second direction Y intersect each other. Specifically, the two rods 30 within the connecting rod refer to the two rods 30 connected to the connecting member 10. The second direction intersects each other with the concave direction of the opening K of the bearing space E and the side-by-side arrangement direction of the two rods 30 within the connecting rod, i.e., along the projection of the first direction X, the extension direction of the edge formed by the connecting rod intersects with the second direction Y. Optionally, the concave direction of the opening K of the bearing space E, the side-by-side arrangement direction of the two rods 30 within the connecting rod, and the second direction Y are perpendicular to each other. Specifically, one of the two first portions 112 is closer to the interior of the bearing space E, and the other of the two first portions 112 is farther from the interior of the bearing space E.

[0086] The second part 113 can act as a stop. When the pivot end 30a of the rod 30 has an upward tendency, the second part 113 blocks the movement path of the pivot end 30a from above, thereby constraining the rotational degree of freedom of the rod 30. Optionally, a blocking element is provided between the second part 113 and the pivot end 30a along the first direction X.

[0087] Optionally, the connecting body 11 includes a connecting hole 13, which is disposed in the first part 112. The end of the rod 30 is inserted into the U-shaped groove space. The weight of the rod 30 and its load is borne by the first part 112. When the rod 30 is subjected to downward (opposite to the opening K) pressure, the first part 112 can disperse the pressure to the entire connecting body 11, thereby reducing the possibility of stress concentration and improving the overall stability and structural strength.

[0088] The locking assembly 40 passes through the first part 112. A pivot end 30a of the rod 30 is provided between the locking assembly 40 and the second part 113 along the first direction X. In other words, the locking assembly 40 can pass through both first parts 112 and the pivot end 30a of the rod 30 sandwiched between them. In the locked state, the locking assembly 40, by being positioned on the rotation path of the pivot end 30a of the rod 30, prevents the rod 30 from rotating around the pivot 12, thereby achieving locking. Through this arrangement, the load-bearing capacity of the rod 30 is borne by the first part 112, while the locking of the rod 30 is borne by the locking assembly 40. Separating these two functions helps reduce the risk of shear failure of the locking assembly 40 under long-term heavy loads and improves the service life of the locking assembly 40.

[0089] Optionally, the connector 10 may also include a housing that covers the connector body 11. For example... Figure 3 As shown, the blocking member 20 can be disposed between the housing and the connecting body 11. For example... Figure 9 As shown, the blocking member 20 can also be provided on the side of the housing facing away from the connecting body 11.

[0090] In some alternative embodiments, please continue to refer to Figure 6 , Figure 8 , Figure 9 as well as Figure 10 The locking assembly 40 includes a first locking member 41, a second locking member 42, a pushing member 43, and an elastic member 44. Both the first locking member 41 and the second locking member 42 include a connected pushing portion and a locking portion. Along a first direction X, the pushing portion is located on the side of the locking portion facing away from the second part 113. The pushing portions of the first locking member 41 and the second locking member 42 are arranged opposite each other along the extension direction of the two rods 30. In the locked state, the locking portion abuts against the end face of the pivot end 30a of the rod 30. The first direction X is parallel to the recessed direction of the opening K of the bearing space E. The pushing member 43 is configured such that, when pressed, it pushes the pushing portions of the first locking member 41 and the second locking member 42 to move away from each other, thereby separating the locking portion from the end face of the pivot end 30a of the rod 30.

[0091] Optionally, the first locking member 41 and the second locking member 42 are symmetrically or mirror-imagely arranged. The push portion may include a first push portion 411, which is the push portion of the first locking member 41. The push portion may include a second push portion 421, which is the push portion of the second locking member 42. The locking portion may include a first locking portion 412, which is the locking portion of the first locking member 41. The locking portion may include a second locking portion 422, which is the locking portion of the second locking member 42. Specifically, the first locking member 41 includes a first push portion 411 and a first locking portion 412. The second locking member 42 includes a second push portion 421 and a second locking portion 422. Two rods 30 pivotally connected to a connector 10 are a first rod 31 and a second rod 32. A first locking part 412 abuts against the end face of the pivot end 30a of the first rod 31, and a second locking part 422 abuts against the end face of the pivot end 30a of the second rod 32. Along the first direction X, a first pushing part 411 is disposed on the side of the first locking part 412 facing away from the second part 113. Along the first direction X, a second pushing part 421 is disposed on the side of the second locking part 422 facing away from the second part 113. The first locking part 412 and the second locking part 422 are arranged opposite to each other along the extending direction of the two rods 30. The first pushing part 411 and the second pushing part 421 are arranged opposite to each other along the extending direction of the two rods 30.

[0092] The pusher 43, acting as a trigger element, is configured to abut against the pusher portion of the first locking member 41 and the pusher portion of the second locking member 42 when pressed, thereby separating the locking portion from the end face of the pivot end 30a of the rod 30. In the locked state, the first locking portion 412 abuts against the end face of the pivot end 30a of the first rod 31, thereby restricting the rotation of the first rod 31 and locking the first rod 31. In the locked state, the second locking portion 422 abuts against the end face of the pivot end 30a of the second rod 32, thereby restricting the rotation of the second rod 32 and locking the second rod 32. At this time, the thrust of the elastic member 44 causes the first locking portion 412 and the second locking portion 422 to abut against the end faces of the pivot end 30a of the first rod 31 and the second rod 32, respectively, thereby preventing the rod 30 from rotating. The pusher 43 may be spaced apart from the pusher portion, or the pusher 43 may be in contact with the pusher portion, but the pusher 43 does not apply force to the pusher portion.

[0093] During unlocking, pressure is applied to the pusher 43 to push the first pusher 411 and the second pusher 421 to move in opposite directions. Since the first pusher 411 and the first locking part 412 are an integral structure, when the first pusher 411 moves away from the second pusher 421, the first locking part 412 moves towards the second locking part 422, so that the first locking part 412 separates from the end face of the pivot end 30a of the first rod 31. Similarly, when the second pusher 421 moves away from the first pusher 411, the second locking part 422 moves towards the first locking part 412, so that the second locking part 422 separates from the end face of the pivot end 30a of the second rod 32, thereby achieving unlocking.

[0094] Optionally, the surface of the pusher 43 that contacts the pusher portion can be an inclined surface, allowing the first pusher portion 411 and the second pusher portion 421 to move in opposite directions by inserting a gap between them. Alternatively, the first pusher portion 411 and the second pusher portion 421 can also move in opposite directions by inserting a space between them. Further, the surface of the pusher portion that contacts the pusher 43 can be an inclined surface. For example, the first pusher portion 411 includes a first inclined surface that abuts against the pusher 43. The inclination direction of the first inclined surface and the moving direction of the pusher 43 form an angle. The second pusher portion 421 includes a second inclined surface that abuts against the pusher 43. The inclination direction of the second inclined surface and the moving direction of the pusher 43 form an angle.

[0095] Optionally, the locking component 40 may further include a self-locking structure 47, which is disposed in the moving direction of the pushing member 43, and the cross-sectional shape of the self-locking structure 47 along the moving direction of the pushing member 43 is triangular, conical, or other shapes. When the pushing member 43 tends to move away from the pushing part, the self-locking structure 47 locks the pushing member 43, preventing the pushing member 43 from continuing to move away from the pushing part.

[0096] Optionally, the locking assembly 40 may further include a cover 46 and a positioning member 45. The positioning member 45 is fixedly connected to the first portion 112 of the connecting body 11. The cover 46 is accommodated in the positioning member 45 and covers the portion of the positioning member 45 that is fixedly connected to the connecting body 11. Optionally, the positioning member 45 is provided with a connecting structure 451, through which the positioning member 45 is connected to the first portion 112 of the connecting member 10.

[0097] In the above embodiment, by performing a single action (such as pressing) on ​​the pusher 43, both locking members can be driven to move simultaneously, thus achieving overall unlocking and reducing the operation process. At the same time, the restoring force of the elastic member 44 ensures that the entire locking mechanism remains in the locked state by default, i.e., a fail-safe design. When an accident occurs (such as the user forgetting to lock), the locking mechanism will automatically return to the safe state (locked state), reducing the possibility of accidental folding of the frame structure 100 and improving the safety of the crib.

[0098] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0099] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
