Description

Technical Field

[0001] This utility model relates to the technical field of children's products, and in particular to a bed frame structure with auxiliary support and a bed skeleton. Background Technology

[0002] Bed surround frames are typically used for infants or toddlers to sleep and move around. They are designed to provide a safe and comfortable environment. The bed surround base frame structure, as an important component supporting the overall bed surround frame, directly affects its safety and stability. Currently, most bed surround frames on the market achieve support through the assembly of bed surround columns.

[0003] In many traditional designs, the base frame of the bed is suspended, relying mainly on the bed support columns to support the entire device. While this design simplifies the structure, the suspension of the base frame limits the stability and support strength of the entire bed, making it prone to swaying or tilting during use, thus affecting safety.

[0004] Another common design is to allow the joint seats in the bed frame structure to touch the ground directly. This design provides a certain degree of support through the combination of the bed uprights and the joint seats. However, since the joint seats are often individual support points, their bearing capacity is limited and they cannot effectively disperse or absorb the force generated by use, resulting in unsatisfactory support strength.

[0005] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0006] The existing bed frame structures mentioned above mostly rely on the connection of bed frame columns for support, resulting in insufficient support strength.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A bed frame structure with auxiliary support, rotatably connected to the bed uprights, has an unfolded state and a folded state. It includes a joint seat and a base rod assembly, the base rod assembly being rotatably connected between the joint seat and the bed uprights assembly. The base rod assembly also has auxiliary support components. The bed frame structure further includes a linkage assembly; when the bed frame structure moves...

[0009] When moving between the unfolded state and the folded state, the linkage component can move relative to the base rod assembly; when the bed frame structure is in the unfolded state, the bottom of the auxiliary support member can abut against the support plane.

[0010] As described above, in a bed frame structure with auxiliary support, the auxiliary support is rotatably connected to the base rod assembly or connected to the base rod assembly through the linkage component. When the bed frame structure is in a folded state, the auxiliary support can rotate towards the base rod assembly to achieve storage.

[0011] As described above, a bed frame structure with auxiliary support includes a sliding member, a first folding motion rod, and a second folding motion rod. The first folding motion rod is rotatably connected between the sliding member and the joint seat, and the second folding motion rod is rotatably connected between the sliding member and the bed upright assembly.

[0012] The sliding member is slidably connected to the bottom rod assembly, and the auxiliary support member is movably connected to the linkage assembly.

[0013] As described above, in a bed frame structure with auxiliary support, the linkage component further includes a support linkage rod, which is rotatably connected between the auxiliary support and the bottom rod assembly, and the auxiliary support is rotatably connected to the sliding member;

[0014] or;

[0015] The support linkage rod is rotatably connected between the auxiliary support and the sliding member, and the auxiliary support is rotatably connected to the bottom rod assembly.

[0016] As described above, in a bed frame structure with auxiliary support, the sliding member includes a sleeve fitted onto the bottom rod assembly, one end of the auxiliary support is pivotally connected to the sleeve, the other end of the auxiliary support is pivotally connected to one end of the support linkage rod, and the other end of the support linkage rod is pivotally connected to the bottom rod assembly.

[0017] As described above, a bed frame structure with auxiliary support includes a sliding member comprising a sleeve fitted onto a bottom rod assembly and a folding motion rod pivot section disposed on the sleeve. One end of the first folding motion rod and / or the second folding motion rod is pivotally connected to the folding motion rod pivot section, which is located at the top of the sleeve.

[0018] Alternatively, one end of the first folding rod and / or the second folding rod may be higher than the bottom rod assembly.

[0019] As described above, in a bed frame structure with auxiliary support, the linkage component includes a support linkage rod;

[0020] One end of the auxiliary support member near the support plane is movably connected to the support member linkage rod;

[0021] When the bed frame structure moves between the unfolded state and the folded state, the support linkage rod drives the auxiliary support to fold or unfold.

[0022] As described above, in a bed frame structure with auxiliary support, the linkage component further includes at least one folding motion rod;

[0023] One end of the at least one folding motion rod is rotatably connected to the bed frame column assembly or the joint seat;

[0024] The auxiliary support is movably connected to at least one of the folding motion rods. When the bed frame structure moves between the unfolded state and the folded state, the at least one of the folding motion rods drives the auxiliary support to move.

[0025] As described above, in a bed frame structure with auxiliary support, the linkage component further includes a sliding member, which is slidably connected to the bottom rod assembly, and the other end of at least one of the folding motion rods is rotatably connected to the sliding member;

[0026] And / or, the supporting linkage rod is rotatably connected to the bottom rod assembly.

[0027] In the above-described bed frame structure with auxiliary support, the first folding motion rod and the second folding motion rod are respectively located on both sides of the pivot section of the folding motion rod.

[0029] As described above, in a bed frame structure with auxiliary support, the base rod assembly includes multiple base frame main rods, and the auxiliary support components are correspondingly arranged with the base frame main rods.

[0030] A bed frame includes an upper bed frame structure, a bed support column assembly, and a bed base frame structure with auxiliary support as described above. The bed support column assembly is rotatably connected between the upper bed frame structure and the bottom rod assembly. The upper bed frame structure has an unfolded state and a folded state. When the joint seat is pushed down, the bottom rod assembly can respond to the movement of the joint seat and switch from the folded state to the unfolded state. The bottom rod assembly drives the upper bed frame structure to switch from the folded state to the unfolded state through the bed support column assembly.

[0031] The beneficial effects of this utility model are:

[0032] This utility model relates to the technical field of children's products, specifically a bed frame structure with auxiliary support and a bed skeleton. The bed frame structure is rotatably connected to the bed uprights, and has an unfolded and folded state. The bed frame structure includes a joint seat and a base rod assembly, which is rotatably connected between the joint seat and the bed uprights. By providing auxiliary support members on the base rod assembly, when the bed frame structure is in the unfolded state, the bottom of the auxiliary support member can abut against the supporting plane. This increases the contact area between the bed frame structure and the supporting plane in the unfolded state, providing additional support points, effectively dispersing the force borne by the bed frame structure, lowering the center of gravity of the bed, reducing the possibility of swaying and tilting, and, through the combination of the base rod assembly and the auxiliary support members, can withstand greater loads and improve overall support strength.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0039] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0040] like Figures 1 to 5As shown, this embodiment presents a bed frame structure with auxiliary support, which is rotatably connected to the bed upright assembly 2 and has an unfolded state and a folded state. It includes a joint seat 11 and a base rod assembly 12, the base rod assembly 12 being rotatably connected between the joint seat 11 and the bed upright assembly 2. Specifically, by providing an auxiliary support member 4 on the base rod assembly 12, the bed frame structure also includes a linkage component 5. When the bed frame structure moves between the unfolded and folded states, the linkage component 5 can move relative to the base rod assembly 12. When the bed frame structure is in the unfolded state, the bottom of the auxiliary support 4 can abut against the supporting plane (such as the ground). This design allows the auxiliary support 4 on the bottom rod assembly 12 to touch the ground when the bed frame is in the unfolded state, increasing the contact area between the bed frame structure and the supporting plane, providing additional support points, effectively dispersing the force borne by the bed frame structure, lowering the center of gravity of the bed, reducing the possibility of swaying and tilting, and through the combination of the bottom rod assembly and the auxiliary support, it can withstand greater loads and improve the overall support strength.

[0041] like Figures 1 to 5 As shown, the linkage component 5 in this embodiment includes a support linkage rod 54; one end of the auxiliary support 4 near the support plane is movably connected to the support linkage rod 54. With this design, when the bed frame structure moves between the unfolded state and the folded state, the linkage component 5 can move relative to the base rod assembly 12, and the support linkage rod 54 can drive the auxiliary support 4 to fold or unfold. That is, when the bed frame structure changes between the unfolded and folded states, the auxiliary support 4 can fold or unfold synchronously. This synchronicity simplifies the operation process and reduces the steps required for users to adjust the bed. Users do not need to adjust the auxiliary support 4 separately; they only need to operate the bed frame structure to complete the entire folding or unfolding process. This design reduces the complexity of manual operation, improves ease of use, and is suitable for a wide range of users.

[0042] like Figures 1 to 5 As shown, the linkage component 5 in this embodiment also includes at least one folding motion rod 52 / 53; one end of the at least one folding motion rod 52 / 53 is rotatably connected to the bed frame column assembly 2 or the joint seat 11. The introduction of the folding motion rod can simplify the overall structure of the bed frame, making the unfolding and folding process of the bed frame more efficient. Compared with complex mechanical structures, the use of the folding motion rod can reduce manufacturing costs and assembly difficulty.

[0043] Preferably, the auxiliary support 4 is movably connected to at least one of the folding motion rods 52 / 53. When the bed frame structure moves between the unfolded state and the folded state, at least one of the folding motion rods 52 / 53 drives the auxiliary support 4 to move. The folding motion rods 52 / 53 achieve mechanical movement of the auxiliary support 4 through rotational connection with the bed column assembly 2 or the joint seat 11. This allows the auxiliary support 4 to change between the unfolded and folded states under the drive of the support linkage rod 54. At least one of the folding motion rods 52 / 53 can drive the other end of the auxiliary support 4 to move on the bottom rod assembly 12 to adjust the angle between the auxiliary support 4 and the support linkage rod 54. This further simplifies the operation process of the auxiliary support 4 changing between the unfolded and folded states. This design makes the force transmission more direct and effective, ensuring that the auxiliary support can be smoothly folded or unfolded during the bed state transition.

[0044] like Figures 1 to 5 As shown, the linkage component 5 in this embodiment also includes a slider 51, which is slidably connected to the bottom rod assembly 12, and at least one of the folding motion rods 52 / 53 is rotatably connected to the slider 51.

[0045] And / or, the support linkage rod 54 is rotatably connected to the bottom rod assembly 12.

[0046] Specifically, the design of the sliding component 51 allows the folding motion rods 52 / 53 to slide freely on the base rod assembly 12. This sliding connection allows the bed enclosure to have greater flexibility between the unfolded and folded states, and its position can be adjusted according to actual needs, thereby optimizing the user experience of the bed enclosure.

[0047] Furthermore, the slider 51 provides a sliding motion, which makes the folding motion lever move more smoothly, reducing friction and wear, thereby making the unfolding and folding process of the bed frame more stable. This stability is very important for the user experience.

[0048] Furthermore, the rotatable connection between the support linkage rod 54 and the bottom rod assembly 12 improves the stability of the overall structure. This connection ensures the reliability of the support in different states, especially when the bed is in use, the support can effectively support the weight of the bed.

[0049] Specifically, such as Figures 1 to 5As shown, the linkage component 5 in this embodiment includes a slider 51, a first folding motion rod 52, and a second folding motion rod 53. The first folding motion rod 52 is rotatably connected between the slider 51 and the joint seat 11, and the second folding motion rod 53 is rotatably connected between the slider 51 and the bed frame column assembly 2. The slider 51 is slidably connected to the bottom rod assembly 12. That is, there are two folding motion rods in this embodiment. With this design, when the joint seat 11 is pushed down, the slider 51 slides on the bottom rod assembly 12, causing the first folding motion rod 52 and the second folding motion rod 53 to move away from each other, so as to drive the bottom rod assembly 12 to unfold outward. When the joint seat 11 is pushed up, the slider 51 slides in the opposite direction on the bottom rod assembly 12, causing the first folding motion rod 52 and the second folding motion rod 53 to move closer to each other, so as to drive the bottom rod assembly 12 to fold inward.

[0050] Preferably, by movably connecting the auxiliary support 4 to the linkage assembly 5, the structure of the bed frame becomes more compact, which helps to reduce the volume of the bed frame.

[0051] like Figures 1 to 5 As shown, the linkage component 5 in this embodiment includes a support linkage rod 54, which is rotatably connected between the auxiliary support 4 and the bottom rod assembly 12, and the auxiliary support 4 is rotatably connected to the sliding member 51.

[0052] With this design, when the joint seat 11 is pushed down, the sliding member 51 slides on the bottom rod assembly 12, causing the first folding motion rod 52 and the second folding motion rod 53 to move away from each other, thereby driving the bottom rod assembly 12 to unfold outward. At the same time as the bottom rod assembly 12 unfolds, the support member linkage rod 54 rotates around the connection point with the bottom rod assembly 12 in a direction away from the bottom rod assembly 12. At this time, the sliding member 51 moves towards the support member linkage rod 54. Under the linkage of the two, the auxiliary support member 4 is driven to rotate to the unfolded position.

[0053] Preferably, during this process, the support linkage rod 54 and the auxiliary support 4 move closer to each other, and the included angle between them becomes smaller and smaller.

[0054] Preferably, the support linkage rod 54 is connected between the auxiliary support 4 and the bottom rod assembly 12 to ensure that the auxiliary support 4 provides stable support after deployment.

[0055] When the joint seat 11 is pushed up, the slider 51 slides in the opposite direction on the bottom rod assembly 12, causing the first folding motion rod 52 and the second folding motion rod 53 to move towards each other, thereby driving the bottom rod assembly 12 to fold inward. At the same time as the bottom rod assembly 12 folds inward, the support linkage rod 54 rotates around the connection point with the bottom rod assembly 12 towards the bottom rod assembly 12. At this time, the slider 51 moves away from the support linkage rod 54. Under the linkage of the two, the auxiliary support 4 is driven to rotate to the storage position.

[0056] This process involves the auxiliary support 4 rotating to a position close to the bottom rod assembly 12 via the support linkage rod 54 and the sliding member 51, thereby achieving an inward retraction effect. With this design, the auxiliary support 4 can follow the bottom rod assembly 12 and synchronously switch to the unfolded or folded state without the need for secondary adjustments. This design has the advantages of simple structure and convenient operation.

[0057] Preferably, during this process, the support linkage rod 54 and the auxiliary support 4 move further apart, and the included angle between them becomes larger and larger.

[0058] In other embodiments, the support linkage rod 54 is rotatably connected between the auxiliary support 4 and the sliding member 51. The auxiliary support 4 is rotatably connected to the bottom rod assembly 12. Specifically, in this embodiment, the sliding member 51 is not connected to the auxiliary support 4. The auxiliary support 4 is rotatably connected to the bottom rod assembly 12, and the sliding member 51 is slidably connected to the main rod of the base frame. The support linkage rod 54 is rotatably connected to both the auxiliary support 4 and the sliding member 51. The sliding member 51 slides on the bottom rod assembly 12, causing the first folding motion rod 52 and the second folding motion rod 53 to unfold. During this process, the auxiliary support 4 is unfolded by the support linkage rod 54. The connection between the auxiliary support 4 and the bottom rod assembly 12 provides additional support and stability after unfolding.

[0059] When the slider 51 slides in the opposite direction, the first folding rod 52 and the second folding rod 53 begin to move closer together, causing the auxiliary support 4 to fold inward. During this process, the support linkage rod 54 plays a role in coordinating the folding of the auxiliary support 4, making it fit tightly against the bottom rod assembly 12. A suitable design can be selected according to actual needs.

[0060] In other embodiments, when the joint seat 11 is pushed down, the slider 51 slides on the bottom rod assembly 12, causing the first folding motion rod 52 and the second folding motion rod 53 to move away from each other, thereby driving the bottom rod assembly 12 to unfold outward. Simultaneously, as the bottom rod assembly 12 unfolds, the support linkage rod 54 moves away from the bottom rod assembly 12 around its connection point with the bottom rod assembly 12.

[0061] When the linkage 12 rotates, the sliding member 51 moves away from the linkage rod 54 of the support member. Under the linkage of the two, the auxiliary support member 4 is driven to rotate to the unfolded position.

[0062] Preferably, during this process, the support linkage rod 54 and the auxiliary support 4 move further apart, and the included angle between them becomes larger and larger.

[0063] When the joint seat 11 is pushed up, the slider 51 slides in the opposite direction on the bottom rod assembly 12, causing the first folding motion rod 52 and the second folding motion rod 53 to move towards each other, thereby driving the bottom rod assembly 12 to fold inward. At the same time as the bottom rod assembly 12 folds inward, the support linkage rod 54 rotates around the connection point with the bottom rod assembly 12 towards the bottom rod assembly 12. At this time, the slider 51 moves towards the support linkage rod 54. Under the linkage of the two, the auxiliary support 4 is driven to rotate to the storage position.

[0064] Preferably, during this process, the support linkage rod 54 and the auxiliary support 4 move closer to each other, the included angle between the support linkage rod 54 and the auxiliary support 4 becomes smaller and smaller, and the support linkage rod 54 and the auxiliary support 4 almost overlap, or, in some other embodiments, the user can also manually operate the auxiliary support 4 to rotate open or rotate and store on the bottom rod assembly 12 (in embodiments without the support linkage rod 54).

[0065] like Figures 1 to 5 As shown, in some other embodiments, the auxiliary support 4 is rotatably connected to the base rod assembly 12, which allows the support to rotate freely within a certain angle range.

[0066] When the bed frame structure is in the folded state, the auxiliary support 4 can rotate around the connection point toward the bottom rod assembly 12. In the fully folded state, the auxiliary support 4 can be close to or adjacent to the bottom rod assembly 12, thereby reducing the space occupied by the auxiliary support 4 in the folded bed frame structure and making the folded bed frame more compact.

[0067] Preferably, the auxiliary support 4 can be connected to the base rod assembly 12 through a hinge, pivot or other rotation mechanism. The auxiliary support 4 can be manually adjusted to be in an unfolded or folded state, or by means of linkage or other means. A suitable design can be selected according to actual needs.

[0068] like Figures 1 to 5As shown, the sliding member 51 in this embodiment includes a sleeve 511 sleeved on the bottom rod assembly 12. One end of the auxiliary support member 4 is pivotally connected to the sleeve 511, and the other end of the auxiliary support member 4 is pivotally connected to one end of the support member linkage rod 54. The other end of the support member linkage rod 54 is pivotally connected to the bottom rod assembly 12.

[0069] Specifically, when the bed frame needs to be unfolded, the joint seat 11 is pushed down, and the first folding motion rod 52 can push the sleeve 511 to slide on the bottom rod assembly 12. At the same time, the sleeve 511 drives the second folding motion rod 53 to rotate. The first folding motion rod 52 and the second folding motion rod 53 rotate and unfold in a direction away from each other under the drive of the sleeve 511, so as to realize the unfolding of the bottom rod assembly 12 between the joint seat 11 and the bed support column assembly 2.

[0070] Furthermore, as the sleeve 511 moves, it simultaneously drives the support linkage rod 54. The support linkage rod 54 coordinates the unfolding action of the auxiliary support 4 through the pivotal connection at both ends, thereby realizing the unfolding of the auxiliary support 4 and ensuring that the auxiliary support 4 provides stable support after unfolding.

[0071] When the bed frame needs to be folded, the joint seat 11 is pushed up, and the first folding motion rod 52 can push the sleeve 511 to slide in the opposite direction on the bottom rod assembly 12. At the same time, the sleeve 511 drives the second folding motion rod 53 to rotate. The first folding motion rod 52 and the second folding motion rod 53 rotate and fold towards each other under the drive of the sleeve 511, so as to realize the folding of the bottom rod assembly 12 between the joint seat 11 and the bed frame upright assembly 2.

[0072] Furthermore, as the sleeve 511 moves, it simultaneously drives the support linkage rod 54. The support linkage rod 54 coordinates the folding action of the auxiliary support 4 through the pivotal connection at both ends, thereby realizing the folding of the auxiliary support 4.

[0073] Through the design of sliding parts, folding motion rods, and support linkage rods, the bed can be folded and unfolded quickly and easily. The multi-rod linkage mechanism can effectively reduce the volume when folded, making it convenient for storage and carrying.

[0074] In the deployed state, the support linkage rod and auxiliary support provide additional support, ensuring the stability of the overall structure and the safety of use.

[0075] like Figures 1 to 5As shown, in this embodiment, one end of the first folding motion rod 52 and / or the second folding motion rod 53 is higher than the bottom rod assembly 12. The fact that one end of the folding motion rod is higher than the bottom rod assembly 12 makes the movement trajectory of the motion rod more natural during the folding or unfolding of the bed. This design can reduce movement resistance, ensure smooth movement, and avoid jamming between the folded and unfolded states.

[0076] Specifically, by designing one end of the folding motion rod to be higher than the bottom rod, the stability of the bed can be enhanced in the unfolded state. The higher connection point can better distribute the force and reduce the risk of tilting or instability caused by uneven force.

[0077] Furthermore, this design helps improve the overall space utilization efficiency of the bed frame. Since one end of the moving rod is higher than the bottom rod, the vertical space of the bed frame can be better utilized, thereby reducing the horizontal area occupied when folded up, making it convenient for storage in small spaces.

[0078] Furthermore, since one end of the folding motion rod is higher than the bottom rod, it can effectively reduce frictional contact between the rods and reduce wear. At the same time, the optimized torque and force angle can reduce component fatigue and improve the service life of the entire system.

[0079] The sliding member 51 in this embodiment also includes a folding motion rod pivot section 512 disposed on the sleeve 511. One end of the first folding motion rod 52 and / or the second folding motion rod 53 is pivotally connected to the folding motion rod pivot section 512. The folding motion rod pivot section 512 is disposed at the top of the sleeve 511. With this design, the folding motion rod pivot section 512 can provide an assembly position for the folding motion rod, so that one end of the first folding motion rod 52 and / or the second folding motion rod 53 is higher than the bottom rod assembly 12. It has the advantages of simple structure and convenient operation.

[0080] Preferably, the sliding member 51 further includes an auxiliary support pivot section 513 disposed on the sleeve 511. One end of the auxiliary support member 4 is pivotally connected to the auxiliary support pivot section 513. The auxiliary support pivot section 513 provides an assembly position for the auxiliary support member 4, which facilitates the assembly of the auxiliary support member 4 onto the sliding member 51 and also facilitates the maintenance of the auxiliary support member 4. It has the advantages of simple structure and convenient operation.

[0081] Specifically, in this embodiment, the folding motion rod pivot section 512 is located at the top of the sleeve 511, and the auxiliary support pivot section 513 is located at the bottom of the sleeve 511. This allows the folding motion rod and the support linkage rod to be in different vertical spaces during operation, avoiding collisions between them. Since the folding motion rod and the auxiliary support are connected at different positions, they rotate independently during unfolding and folding without interfering with each other, ensuring the normal operation of each component.

[0082] Preferably, this design makes the entire bed more compact when folded, taking up less storage space, while providing better support and stability when unfolded.

[0083] Specifically, when the bed frame needs to be unfolded, the joint seat 11 is pushed down, and the first folding motion rod 52 can push the sleeve 511 to slide on the bottom rod assembly 12 through the folding motion rod pivot section 512. At the same time, the sleeve 511 drives the second folding motion rod 53 to rotate. The first folding motion rod 52 and the second folding motion rod 53 rotate and unfold in a direction away from each other under the drive of the folding motion rod pivot section 512 of the sleeve 511, so as to realize the unfolding of the bottom rod assembly 12 between the joint seat 11 and the bed support column assembly 2.

[0084] Furthermore, as the sleeve 511 moves, the pivot section 513 of the auxiliary support member also drives the linkage rod 54 of the support member through the auxiliary support member 4. The linkage rod 54 of the support member coordinates the unfolding action of the auxiliary support member 4 through the pivot connection at both ends, thereby realizing the unfolding of the auxiliary support member 4 and ensuring that the auxiliary support member 4 provides stable support after unfolding.

[0085] When the bed frame needs to be folded, the joint seat 11 is pushed up. The first folding motion rod 52 can push the sleeve 511 to slide in the opposite direction on the bottom rod assembly 12 through the folding motion rod pivot section 512. At the same time, the sleeve 511 drives the second folding motion rod 53 to rotate. The first folding motion rod 52 and the second folding motion rod 53 rotate and fold towards each other under the drive of the folding motion rod pivot section 512 of the sleeve 511, so as to realize the folding of the bottom rod assembly 12 between the joint seat 11 and the bed frame column assembly 2.

[0086] Furthermore, as the sleeve 511 moves, the pivot section 513 of the auxiliary support member also drives the linkage rod 54 of the support member through the auxiliary support member 4. The linkage rod 54 of the support member coordinates the folding action of the auxiliary support member 4 through the pivot connection at both ends, thereby realizing the folding of the auxiliary support member 4.

[0087] Through the design of sliding parts, folding motion rods, and support linkage rods, the bed can be folded and unfolded quickly and easily. The multi-rod linkage mechanism can effectively reduce the volume when folded, making it convenient for storage and carrying.

[0088] In the deployed state, the support linkage rod and auxiliary support provide additional support, ensuring the stability of the overall structure and the safety of use.

[0089] like Figures 1 to 5 As shown, in this embodiment, the first folding rod 52 and the second folding rod 53 are respectively disposed on both sides of the pivot section 512 of the folding rod.

[0090] Specifically, the design of distributing the first folding rod 52 and the second folding rod 53 on both sides of the pivot section 512 allows the load to be evenly distributed, improving the stability and robustness of the entire structure. Furthermore, this design makes the force transmission more efficient and uniform, reducing unnecessary stress concentration and thus extending the service life of each component.

[0091] Specifically, the first folding rod 52 and the second folding rod 53 can be simultaneously unfolded and folded under the drive of the pivot section 512 of the folding rod, which significantly improves the operating efficiency.

[0092] Preferably, by distributing the motion rods on both sides of the folding motion rod pivot section 512, the design of the overall structure can be simplified, and the manufacturing difficulty and cost can be reduced.

[0093] Furthermore, the first folding rod 52 and the second folding rod 53 are respectively located on both sides of the pivot section 512 of the folding rod, which can also provide sufficient rotation space for the auxiliary support 4 located at the bottom of the sleeve 511, avoid the auxiliary support 4 from touching the folding rod in the folded state, and ensure that the auxiliary support 4 can be folded as close as possible to the bottom rod assembly 12 and can be fully unfolded.

[0094] like Figures 1 to 5 As shown, the number of auxiliary support members 4 in this embodiment is at least two, and the two auxiliary support members 4 are symmetrically arranged on the bottom rod assembly 12.

[0095] Specifically, at least two auxiliary support members 4 are symmetrically arranged on the bottom rod assembly 12 to make the bed frame more balanced when unfolded and folded, avoiding tilting or instability caused by unilateral support.

[0096] Preferably, the number of auxiliary support members 4 is at least two, so that the load can be evenly distributed to multiple support points, reducing the stress on a single point and extending the service life of each component.

[0097] The symmetrical arrangement of multiple auxiliary support components enhances the overall stability of the structure, thereby improving safety during use, especially in terms of load-bearing capacity.

[0098] like Figures 1 to 5As shown, the base rod assembly 12 in this embodiment includes multiple base frame main rods 121, and the auxiliary support 4 is correspondingly arranged with the base frame main rods 121.

[0099] Specifically, the design of the auxiliary support 4 corresponding to the main frame 121 is adopted, so that each main frame 121 is equipped with an auxiliary support 4. Through multiple support points, the load is distributed more evenly, reducing the stress on a single point and enhancing the stability of the entire structure.

[0100] like Figures 1 to 5 As shown, the auxiliary support 4 in this embodiment includes a support foot with a support plane at the bottom. Specifically, the support plane of the support foot provides a larger contact area, which enhances the stability of the overall structure. Multiple support points distribute the load more evenly through the support plane, reducing the force on a single point.

[0101] Preferably, the support plane can reduce pressure concentration on the support plane, reduce wear, and extend service life.

[0102] like Figures 1 to 5 As shown, this embodiment of a bed frame includes an upper bed frame structure 3, a bed support column assembly 2, and a bed base frame structure 1 with auxiliary support as described above. The bed support column assembly 2 is rotatably connected between the upper bed frame structure 3 and the bottom rod assembly 12. The upper bed frame structure 3 has an unfolded state and a folded state. When the joint seat 11 is pushed down, the bottom rod assembly 12 can respond to the movement of the joint seat 11, changing from the folded state to the unfolded state. The bottom rod assembly 12 drives the bed support column assembly 2 connected to it to move synchronously. The bed support column assembly 2 unfolds under the drive of the bottom rod assembly 12, transmitting the movement to the upper bed frame structure 3. The upper bed frame structure 3 changes from the folded state to the unfolded state, completing the unfolding of the entire bed.

[0103] Furthermore, under the action of the linkage component 5, when the bottom rod assembly 12 is fully extended, the auxiliary support 4 is also fully extended on the bottom rod assembly 12. In other words, the bed frame column assembly 2 and the bed frame structure 3 are simultaneously extended.

[0104] When the joint seat 11 is pushed up, the bottom rod assembly 12 responds to the reverse movement of the joint seat 11 by operating the joint seat 11 in the opposite direction (e.g., pushing or pulling), and changes from the unfolded state to the folded state. The bed frame assembly 2 and the auxiliary support 4 are driven by the linkage component 5 and fold synchronously with the bottom rod assembly 12. The bed frame structure 3 is driven by the bed frame assembly 2 to return from the unfolded state to the folded state, completing the entire folding process.

[0105] By adding auxiliary support 4 to the bottom of the bed frame, the bed frame can be provided with additional stability, ensuring its sturdiness and reliability in the unfolded state. The storage method is simple and convenient, improving the user experience and safety during use.

[0106] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
