Description

Technical Field

[0001] This utility model relates to the field of living furniture technology, and in particular to a multifunctional bed frame and bed stand. Background Technology

[0002] Traditional bed frames, as basic bedding, are primarily designed to provide support for sleep, and their structural design typically does not allow for expansion into a work surface or desktop. In multi-functional scenarios such as hospital caregivers, homes with limited space, or dormitories, users often need to equip themselves with a separate table for writing, eating, or storing items. This separate design has significant drawbacks:

[0003] First, space utilization is low. Separate desks need to be stored separately, taking up already limited living space. According to statistics from the China Hospital Association, nearly 70% of wards are too small to accommodate both a caregiver's bed and a standard desk simultaneously, causing extreme inconvenience for nursing staff.

[0004] Secondly, the efficiency of function switching is low. Taking medical companion beds as an example, family members need to complete a series of tedious "assembly and disassembly operations" - namely, folding the bed board, disassembling the limiting parts, installing the bracket, fixing the table, etc., which is time-consuming and labor-intensive.

[0005] Therefore, existing bed frames need to be improved to address the issue that they require a separate table to meet dining or storage needs, resulting in low space utilization and low efficiency in switching between functions.

[0006] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0024] Optionally, the rotating bracket includes a first straight rod hinged at its upper end to the U-shaped frame, and a second straight rod fixed at the lower end to both the first straight rod and the movable plate.

[0025] Optionally, the first straight rod and the second straight rod are perpendicular to each other, forming an L-shaped structure;

[0026] Furthermore, the length of the first straight rod is greater than the length of the second straight rod.

[0027] Optionally, the rotating bracket further includes:

[0028] A rotary drive mechanism is mounted on the U-shaped frame, and the drive end of the rotary drive mechanism is connected to the first straight rod for driving the first straight rod to rotate.

[0029] in,

[0030] When the rotary drive mechanism drives the first straight rod to rotate downwards, the second straight rod drives the movable plate to rotate to the folded state.

[0031] When the rotary drive mechanism drives the first straight rod to rotate upward, the second straight rod drives the movable plate to rotate to the unfolded state.

[0032] Optionally, the U-shaped frame includes a headboard and two bed frame side panels located on both sides of the headboard;

[0033] The movable panel is located at the foot of the bed and is connected to the side panel of the bed frame via the rotating bracket.

[0057] This embodiment provides a multifunctional bed frame and bed stand, which can effectively solve the problem that existing bed frames need to be equipped with an independent table to meet the needs of dining or storage, resulting in low space utilization and low efficiency of function switching.

[0058] See Figures 1-3 In this embodiment, the bed frame includes a multifunctional bed frame and a slatted frame 200 detachably mounted on the U-shaped frame 1 of the multifunctional bed frame. Optionally, a plurality of support protrusions 300 are fixed inside the U-shaped frame 1 to support the slatted frame 200.

[0059] The multifunctional bed frame provided in this embodiment includes a U-shaped frame 1, a movable plate 2 located at the opening of the U-shaped frame 1, and a rotating bracket 3 connecting the U-shaped frame 1 and the movable plate 2.

[0060] The movable plate 2 has a folded state in which, when driven, it rotates downward under the guidance of the rotating bracket 3 to cover the opening of the U-shaped frame 1; and an unfolded state in which, when driven, it rotates upward under the guidance of the rotating bracket 3 to be higher than the U-shaped frame 1.

[0061] It should be noted that the core of the multifunctional bed frame lies in the ingenious rotating bracket 3 structure, which enables the movable board 2 to easily and quickly switch between "folded state" and "unfolded state". The specific working process is as follows:

[0062] 1. From folded state to unfolded state

[0063] Initial state: The movable panel 2 is in a folded state. It rotates downwards and perfectly covers the opening of the U-shaped frame 1. At this time, it forms a flat bed surface with the other parts of the bed frame, which is used to place the slatted frame 200 and the mattress 100. Its function is no different from that of an ordinary bed frame.

[0064] Trigger action: When a user needs a table, simply lift the movable board 2 upwards.

[0065] Support Guidance: During the upward lifting of the movable plate 2, the rotating support 3 connecting the movable plate 2 and the U-shaped frame 1 begins to operate. The core function of this rotating support 3 is to guide the movement trajectory of the movable plate 2, ensuring that it does not simply fold upwards, but rather achieves a combined upward and outward movement.

[0066] Reaching the limit: When the movable plate 2 rotates upward to a certain height (significantly higher than the bed surface), the movable plate 2 stops stably in that position.

[0067] Final state: At this point, movable panel 2 is in the unfolded state. It forms a stable surface raised above the bed, which can be immediately used as a dining table, desk, or shelf. The entire conversion process requires no tools and can usually be completed in one step, making it highly efficient.

[0068] II. From unfolded state to folded state

[0069] Initial state: Activity board 2 is in the unfolded state and is being used as a desktop.

[0070] Trigger action: When the user needs to restore the bed surface function, rotate the movable plate 2 downwards;

[0071] Support guidance: At this time, the rotating support 3 guides the movement trajectory of the movable plate 2 again, so that the movable plate 2 falls smoothly and controllably inward and downward.

[0072] Closure complete: The movable panel 2 finally falls back completely, covering the opening of the U-shaped frame 1, restoring a complete and flat bed surface.

[0073] Final state: Activity board 2 returns to its folded state, the tabletop function is hidden, and it does not take up any extra space.

[0074] In the above process, on the one hand, the movable board 2 is connected to the U-shaped frame 1 through the rotating bracket 3. When not in use, the movable board 2 directly serves as a component of the multifunctional bed frame, eliminating the need to find additional space to store the movable board 2 and solving the problem of low space utilization. On the other hand, the switching of the usage state of the movable board 2 can be completed by simple lifting or pressing actions, which is smooth and quick and solves the problem of low efficiency in function switching.

[0075] Therefore, the multifunctional bed frame and bed frame provided by this utility model can effectively solve the problem that existing bed frames need to be equipped with an independent table to meet the needs of dining or storage, resulting in low space utilization and low efficiency of function switching.

[0076] Optionally, when the rotating bracket 3 is in the folded state, the movable plate 2 is in a vertical state; when the rotating bracket 3 is in the unfolded state, the movable plate 2 is in a horizontal state.

[0077] In this embodiment, the rotating support 3 is mainly used to guide the movement of the movable plate 2. Its specific structural form can be a complex multi-link structure or a simple L-shaped rotating rod structure. The following will describe the multi-link structure and the L-shaped rotating rod structure respectively.

[0078] (1) Multi-link structure

[0079] See Figure 2 The rotating support 3 includes:

[0080] A first fixed base plate 301 is fixedly mounted on the U-shaped frame 1;

[0081] The second fixed base plate 302 is fixedly mounted on the movable plate 2;

[0082] The first connecting rod 303 is hinged at one end to the end of the first fixed base plate 301 away from the movable plate 2.

[0083] The second connecting rod 304 has one end hinged to the other end of the first connecting rod 303 and the other end hinged to the end of the second fixed base plate 302 near the first fixed base plate 301.

[0084] The third connecting rod 305 has one end hinged to the end of the first fixed base plate 301 near the movable plate 2, and the middle part of the third connecting rod 305 is hinged to the middle part of the second connecting rod 304.

[0085] The fourth link 306 is hinged at one end to the other end of the third link 305 and at the other end of the second fixed base plate 302 away from the first fixed base plate 301.

[0086] A direct-drive linkage mechanism 307 is rotatably mounted on the U-shaped frame 1, and the drive end of the direct-drive linkage mechanism 307 is hinged to the first linkage member 303.

[0087] in,

[0088] When the drive end of the linkage direct drive mechanism 307 retracts away from the movable plate 2, the movable plate 2 is rotated to the folded state by the rotating bracket 3;

[0089] When the drive end of the linkage direct drive mechanism 307 extends towards the movable plate 2, the movable plate 2 is rotated to the unfolded state by the rotating bracket 3.

[0090] The linkage assembly is designed so that the movable plate 2 will also have a certain lateral displacement relative to the U-shaped frame 1 in a direction away from the U-shaped frame 1 during the upward rotation. This ensures that the movable plate 2 and the U-shaped frame 1 do not overlap vertically in the unfolded state (i.e., the entire movable plate 2 is located outside the U-shaped frame 1). Users can use the movable plate 2 in a normal sitting posture (sitting on the edge of the bed with their legs hanging naturally outside the bed) for reading or working for a long time.

[0091] (2) L-shaped rotating rod structure

[0092] See Figure 3 The rotating bracket 3 includes a first straight rod 308 hinged at its upper end to the U-shaped frame 1, a second straight rod 309 fixedly connecting the lower ends of the first straight rod 308 and the movable plate 2, and a rotating drive mechanism 310. The rotating drive mechanism 310 is mounted on the U-shaped frame 1, and the drive end of the rotating drive mechanism 310 is connected to the first straight rod 308 via a transmission connection (e.g., through a belt 311 or a gear assembly), for driving the first straight rod 308 to rotate.

[0093] in,

[0094] When the rotary drive mechanism 310 drives the first straight rod 308 to rotate downward, the second straight rod 309 drives the movable plate 2 to rotate to the folded state.

[0095] When the rotary drive mechanism 310 drives the first straight rod 308 to rotate upward, the second straight rod 309 drives the movable plate 2 to rotate to the unfolded state.

[0096] The L-shaped support design allows the movable plate 2 to rotate upwards while also shifting laterally towards the U-shaped frame 1. This causes the movable plate 2 to overlap with the U-shaped frame 1 in the vertical direction (i.e., the movable plate 2 is partially or even entirely located above the U-shaped frame 1). Users can use the movable plate 2 in a cross-legged position (sitting on the bed with their legs placed in the space between the movable plate 2 and the slatted frame 200) to reduce the space occupied outside the bed.

[0097] Furthermore, the first straight rod 308 and the second straight rod 309 are perpendicular to each other, forming an L-shaped structure; and the length of the first straight rod 308 is greater than the length of the second straight rod 309, so as to prevent the second straight rod 309 from interfering with the skeleton 200 on the U-shaped frame 1 during the rotation of the first straight rod 308.

[0098] Specifically, when the movable plate 2 rotates, the second straight rod 309 moves synchronously with the first straight rod 308. If the second straight rod 309 is too long or the two rods are of equal length, it is easy for it to collide with the frame 200 on the U-shaped frame during rotation. The first straight rod 308 is longer, which allows the second straight rod 309 to always be in the outer area of ​​the frame 200 during rotation, completely avoiding collision and ensuring smooth switching.

[0099] In this embodiment, the U-shaped frame 1 includes a headboard 101 and two bed frame side panels 102 located on both sides of the headboard 101; the movable panel 2 is located at the foot of the bed and is connected to the bed frame side panels 102 via the rotating bracket 3. The movable panel 2, located at the foot of the bed and connected to the bed frame side panels 102, does not affect the use of the headboard and conforms to the user's daily routine. Operating the movable panel 2 at the foot of the bed is more convenient, and switching states will not interfere with the headboard area, optimizing the user experience and adapting to common bedroom layouts.

[0100] Of course, in some other embodiments, the movable plate 2 may also be located on the side of the bed frame, and this utility model does not limit this.

[0101] In summary, the multifunctional bed frame and bed stand provided in this embodiment have the following advantages:

[0102] ① By setting up a movable plate 2 at the opening of the U-shaped frame and matching it with a rotating bracket 3, the movable plate 2 can be quickly switched between folded and unfolded states. No extra storage space is required and no tools are needed for switching, thus improving space utilization and function switching efficiency.

[0103] ② The rotating bracket 3 adopts a multi-link structure, which allows the unfolded movable plate 2 to move laterally outward relative to the U-shaped frame without vertical overlap, adapting to the user's normal sitting posture and improving the comfort of reading or working for a long time.

[0104] ③ The rotating bracket 3 adopts an L-shaped rotating rod structure (the first straight rod 308 is longer than the second straight rod 309 to prevent interference), so that the unfolded movable plate 2 is partially or entirely located above the U-shaped frame, which can accommodate the user's cross-legged sitting posture and reduce the space occupied outside the bed;

[0105] ④ The movable board 2 is located at the foot of the bed and is connected to the side panel 102 of the bed frame through the rotating bracket 3. It does not interfere with the use of the head of the bed and is easy to operate, which conforms to the user's daily routine and optimizes the adaptability of the bedroom space layout.

[0106] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
