Description

Technical Field

[0001] This utility model relates to the technical field of furniture, and in particular to a silent lift-up bed frame. Background Technology

[0002] As people's living standards improve, their demands for beds are also increasing. Bed frames have evolved from a single, non-deformable structure to a foldable and deformable one, allowing them to better conform to the human body's physiological curves and meet new user needs. Specifically, by making the backrest and legroom of the bed frame foldable, the back and legs can be appropriately raised when a person lies down, thus relieving spinal discomfort.

[0003] However, existing bed frames that can be folded upwards at both ends have the following shortcomings: To allow the backrest and legroom to fold upwards in a controllable manner, actuators are installed to move these positions. However, since a mattress is placed on the bed frame, a high-powered actuator is required to ensure stable upward folding of the backrest and legroom. Therefore, the actuators are often large and heavy. Consequently, the size and weight of the bed beams used to install the actuators also need to be increased accordingly. Since bed frames are typically made of steel, increasing the size and weight of the bed beams not only significantly increases the overall weight of the bed frame but also increases material costs. Therefore, to address these shortcomings, the silent lift bed frame of this application is proposed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a silent lifting bed frame that effectively reduces the size and weight of the bed beams while ensuring the structural strength of the bed frame.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A silent lift-up bed frame includes:

[0007] Base frame; and

[0008] At least one support assembly, wherein each support assembly is spaced apart on the base frame, and in one of the support assemblies, the support assembly includes a main frame, a back frame, a first folding frame, a second folding frame, a connecting rod, a support rod, two support seats, and two drive members. The main frame is disposed on the base frame, one end of the back frame is rotatably disposed on one end of the main frame, both ends of the first folding frame are rotatably connected to the end of the main frame away from the back frame and the second folding frame, respectively, both ends of the connecting rod are rotatably connected to the end of the main frame away from the back frame and the second folding frame, respectively, the two support seats are respectively disposed on opposite ends of the main frame, the support rod is respectively connected to the two support seats, and the two drive members are rotatably disposed on the two support seats, and the output shafts of the two drive members are respectively rotatably connected to the back frame and the first folding frame.

Each crossbar is provided with at least two support columns, and the end of each support column away from the crossbar is connected to the main frame. The main frame is rotatably connected to the back frame / first folding frame, and the end of the crossbar is rotatably connected to the connecting rod.

[0010] Optionally, the support base includes two support plates, both of which are disposed on the main frame and located on opposite sides of the support rod, and both support plates are rotatably connected to the drive member.

[0011] Optionally, the support plate is welded to the main frame and the support rod.

[0012] Optionally, the support piece has a slot, and a portion of the main frame is adapted to be accommodated in the slot.

[0013] Optionally, a top support is provided on the end of the first folding frame / back frame away from the main frame, and the top support is rotatably connected to the output shaft of the drive component.

[0014] Optionally, the top support includes two top support plates, which are spaced apart on the first folding frame / back frame, so that the output shaft of the drive member is located between the two top support plates for rotatable connection with the two top support plates.

[0028] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0029] like Figures 1 to 6 As shown, a silent lifting bed frame 10 includes a base frame 100 and at least one support assembly 200. Each support assembly 200 is spaced apart on the base frame 100. One of the support assemblies 200 includes a main frame 210, a back frame 220, a first folding frame 230, a second folding frame 240, a connecting rod 250, a support rod 260, two support seats 270, and two driving components 280. The main frame 210 is mounted on the base frame 100, and one end of the back frame 220 is rotatably mounted on one end of the main frame 210. The first folding frame... The two ends of 230 are rotatably connected to the end of the main frame 210 away from the back frame 220 and the second folding frame 240, respectively. The two ends of the linkage rod 250 are rotatably connected to the end of the main frame 210 away from the back frame 220 and the second folding frame 240, respectively. The two support seats 270 are respectively set on the opposite ends of the main frame 210. The support rod 260 is respectively connected to the two support seats 270. The two drive members 280 are respectively rotatably set on the two support seats 270, and the output shafts of the two drive members 280 are respectively rotatably connected to the back frame 220 and the first folding frame 230.

[0030] It should be noted that the number of support components 200 is set to at least one. For example, one support component 200 can be set on the base frame 100; two support components 200 can also be set on the base frame 100. When two support components 200 are set, there is a gap between the two support components 200, and they are independent of each other. In any specific support component 200, the main frame 210 is fixedly installed in the middle position of the base frame 100 by bolts, the back frame 220 is rotatably installed on one end of the main frame 210, the first folding frame 230 is rotatably installed on the other end of the main frame 210, and the second folding frame 240 is rotatably installed on the end of the first folding frame 230 away from the main frame 210. Thus, when the first folding frame 230, the second folding frame 240, and the back frame 220 are all laid flat on the base frame 100, the first folding frame 230, the second folding frame 240, the back frame 220, and the main frame 210 form a planar structure. Furthermore, the two ends of the linkage 250 are rotatably connected to the main frame 210 and the second folding frame 240, respectively. Furthermore, two support seats 270 are installed at opposite ends of the main frame 210, and the two ends of the support rod 260 are fixedly connected to the two support seats 270, respectively. Two drive members 280 are rotatably installed on the two support seats 270, wherein the output shaft of the drive member 280 located on the side of the back frame 220 is rotatably connected to the back frame 220, and the output shaft of the drive member 280 located on the side of the first folding frame 230 is rotatably connected to the first folding frame 230. In one embodiment, the drive member 280 is an electric cylinder; thus, when the two drive members 280 are activated, they push the back frame 220 and the first folding frame 230 upwards relative to the main frame 210, causing the back frame 220 and the first folding frame 230 to form an angled structure with the main frame 210, respectively. Since the second folding frame 240 is connected to the main frame 210 via the connecting rod 250, the second folding frame 240 will fold downward relative to the first folding frame 230, ultimately transforming the support assembly 200 from a planar structure into a curved structure conforming to a human lying position. During deformation, the drive member 280 pushes the back frame 220 and the first folding frame 230 upwards, so the forces exerted on the drive member 280 by the back frame 220 and the first folding frame 230 are applied to the two support seats 270. Since the two support seats 270 are fixedly installed at both ends of the straight support rod 260, the forces exerted by the back frame 220 and the first folding frame 230 during upward folding are effectively offset by the support rod 260. Because the support rod 260 has a stronger axial load-bearing capacity, and in the prior art, the drive member 280 is directly rotatably mounted at the end of the main frame 210, the dimensions of the bed beam of the main frame 210 need to be designed to be larger to ensure sufficient radial load-bearing capacity.Therefore, in the silent lifting bed frame 10 of this application, through the cooperation of the support rod 260 and the two support seats 270, the force exerted when the back frame 220 and the first folding frame 230 are folded upward can be offset along the axial direction of the support rod 260. Therefore, the bed beams of the main frame 210 and other structures do not need to have their diameter increased, thus effectively reducing the overall weight and material cost of the silent lifting bed frame 10.

[0031] like Figure 5 As shown, in one embodiment, the main frame 210 includes a main frame 211, two crossbars 212 and several support columns 213. The two crossbars 212 are spaced apart on the base frame 100. Each crossbar 212 is provided with at least two support columns 213, and the end of each support column 213 away from the crossbar 212 is connected to the main frame 211. The main frame 211 is rotatably connected to the back frame 220 / first folding frame 230, and the end of the crossbar 212 is rotatably connected to the connecting rod 250.

[0032] It should be noted that the two crossbars 212 are bolted to the base frame 100, and each support column 213 is vertically welded and fixed to the crossbars 212. The main frame 211 is then welded and fixed to the top of each support column 213. This allows the main frame 211 to be supported by the support columns 213 and suspended relative to the base frame 100, thus facilitating the installation of the connecting rod 250, support rod 260, support seat 270, and drive component 280 at the bottom of the main frame 211.

[0033] like Figure 5 As shown, in one embodiment, the support base 270 includes two support plates 271, both of which are disposed on the main frame 211 and are located on opposite sides of the support rod 260. Both support plates 271 are rotatably connected to the drive member 280.

[0034] It should be noted that the two support plates 271 are welded and fixed to the main frame 211 at intervals, and the two support plates 271 are located on opposite sides of the support rod 260, and both support plates 271 are welded and fixed to the support rod 260. The driving component 280 is rotatably installed between the two support plates 271 by bolts. In this way, setting the support base 270 as a combination of two support plates 271 can reduce weight while effectively ensuring the structural strength of the support base 270. When the driving component 280 drives the back frame 220 and the first folding frame 230 to fold upward, the reaction forces applied by the two driving components 280 to the support plates 271 at both ends are transmitted to the support rod 260 to cancel them out.

[0035] like Figure 5 As shown, in one embodiment, the support piece 271 has a slot 2711, and part of the main frame 211 is adapted to be placed in the slot 2711.

[0036] It should be noted that, in order to enhance the structural strength between the support piece 271 and the main frame 211, a slot 2711 is provided on the support piece 271, so that a part of the structure of the main frame 211 fits into the slot 2711, and then the support piece 271 and the main frame 211 are welded and fixed.

[0037] like Figure 5 As shown, in one embodiment, a top support 290 is provided on the end of the first folding frame 230 / back frame 220 away from the main frame 210, and the top support 290 is rotatably connected to the output shaft of the drive member 280.

[0038] It should be noted that in order to enable the drive unit 280 to stably push the first folding frame 230 / back frame 220, a top support seat 290 is welded on the first folding frame 230 / back frame 220 respectively, wherein the top support seat 290 is located on the end of the first folding frame 230 / back frame 220 away from the main frame 210.

[0039] Furthermore, such as Figure 5 As shown, in one embodiment, the top support 290 includes two top support pieces 291, which are spaced apart on the first folding frame 230 / back frame 220, so that the output shaft of the drive member 280 is located between the two top support pieces 291 for rotatable connection with the two top support pieces 291.

[0040] It should be noted that the two top support plates 291 are welded and fixed to the first folding frame 230 / back frame 220 at intervals, and the output shaft of the drive unit 280 is rotatably connected to the two top support plates 291 by passing through bolts.

[0041] Furthermore, such as Figure 5 As shown, in one embodiment, the top support piece 291 has a retaining groove 2911, and the first folding frame 230 / back frame 220 is structurally adapted to be accommodated in the retaining groove 2911.

[0042] It should be noted that a retaining groove 2911 is provided on the top support piece 291, making the top support piece 291 have an L-shaped structure. After the inner sidewall of the retaining groove 2911 abuts against the first folding frame 230 / back frame 220, the top support piece 291 is welded and fixed to the first folding frame 230 / back frame 220. In this way, the structural strength between the top support piece 291 and the first folding frame 230 / back frame 220 can be improved. In one embodiment, a bolt is passed through the output shaft of the drive member 280 and the top support piece 291, so that the output shaft of the drive member 280 is rotatably connected to the top support piece 291.

[0043] like Figures 1 to 6As shown, in one embodiment, a single support component 200 is provided on the base frame 100. Thus, by setting the main frame 210, back frame 220, first folding frame 230, and second folding frame 240 to different widths, the silent lift bed frame 10 can be configured as a single-person or double-person foldable bed frame. Further, in one embodiment, two support components 200 are provided, each independently mounted on the base frame 100. In this way, the silent lift bed frame 10 forms a double-person partitioned foldable bed frame. Specifically, each of the two support components 200 supports an independent mattress. Therefore, in actual use, users in different positions can set the support components 200 to a folded or flat state according to their actual needs, making it more convenient to use.

[0044] like Figure 4 and Figure 5 As shown, in one embodiment, at least two support ears 214 are provided at both ends of the main frame 211, and at least two support columns 2100 are provided at the end of the first folding frame 230 and the back frame 220 near the main frame 211, and each support column 2100 is rotatably connected to each support ear 214.

[0045] It should be noted that the support ear 214 is welded and installed on the main frame 211, and the support column 2100 protrudes from the first folding frame 230 and the back frame 220. Bolts are passed through the support ear 214 and the support column 2100, so that the first folding frame 230 and the back frame 220 are rotatably connected to the main frame 210.

[0046] Furthermore, such as Figure 4 As shown, in one embodiment, the support ear 214 includes an integrally formed U-shaped block 2141 and a protrusion 2142. The protrusion 2142 is disposed on one side of the U-shaped block 2141 so that the protrusion 2142 and the side of the U-shaped block 2141 form a right angle structure.

[0047] In this way, by welding the right-angle structure formed by the protrusion 2142 and the U-shaped block 2141 to the first folding frame 230 and the back frame 220, it can be ensured that the support ear 214 is reliably and stably welded and fixed to the first folding frame 230 and the back frame 220.

[0048] like Figure 4 As shown, in one embodiment, a through hole is provided in the support column 2100, and a rubber sleeve 2110 is inserted into the through hole. The bolt passes through the rubber sleeve and the support lug 214 in sequence.

[0049] It should be noted that the bolt passes through the support lug 214 and the support column 2100, allowing the support column 2100 to rotate relative to the support lug 214. When the bolt passes through the through hole in the support column 2100, the bolt and the support column 2100 are separated by a rubber sleeve. This avoids direct contact between the bolt and the support column 2100, thus preventing noise when the first folding frame 230 and the back frame 220 fold and rotate relative to the main frame 210, enabling the silent lifting bed frame 10 to achieve silent lifting.

[0050] Furthermore, in one embodiment, the structure for the rotatable connection between the second folding frame 240 and the first folding frame 230, and the structure for the rotatable connection between the connecting rod 250 and the main frame 210 / second folding frame 240 are equivalent to the rotatable connection structure between the first folding frame 230 / back frame 220 and the main frame 210, and therefore will not be described in detail.

[0051] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood as including, but not limited to, locking and fixing with screws / bolts, welding, or bonding with adhesives, wherein the adhesives used can be commercially available finished products. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
