[0013] Furthermore, the panel and the transverse keel rod are made of aluminum alloy.

[0014] Furthermore, the longitudinal keel rod is made of aluminum alloy or steel.

[0015] Furthermore, the longitudinal keel rod is in the shape of a U-shaped groove.

[0016] Furthermore, the longitudinal keel rod includes a top wall portion and two side wall portions, the insertion holes are provided on the two side wall portions, and the upper and lower surfaces of the top wall portion are respectively in contact with the panel and the transverse keel rod.

[0017] Furthermore, the transverse keel rod is made of a tubular profile with a rectangular cross section.

[0051] The following is a description of the implementation of the present invention by means of specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0052] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportion relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantial change of the technical content.

[0053] like Figure 1 and Figure 2 As shown, the utility model provides a folding electric bed, comprising:

[0054] Horizontal reference frame 5;

[0055] A bearing seat 4, the bearing seat 4 is arranged on a horizontal reference frame 5;

[0056] A bed board module suitable for an electric bed, the bed board module comprising five bed board modules 1 distributed in sequence, two adjacent bed board modules 1 being hinged to each other through a pin shaft 2, the five bed board modules 1 being respectively used to support the user's head, back, buttocks, thighs and legs and feet, the bed board module for supporting the head being recorded as bed board module A, the bed board module for supporting the back being recorded as bed board module B, the bed board module for supporting the buttocks being recorded as bed board module C, the bed board module for supporting the thigh being recorded as bed board module D, the bed board module for supporting the legs and feet being recorded as bed board module E, the bed board module C being arranged on a bearing seat 4;

[0057] A transmission rod 6, one end of which is hinged to the bearing seat 4 and the other end of which is hinged to the bed board module E;

[0058] The driving system 8 includes a first linear drive 81, a second linear drive 82 and a third linear drive 83. The first linear drive 81 is used to drive the bed board module A to flip relative to the bed board module B, the second linear drive 82 is used to drive the bed board module B to flip relative to the bed board module C, and the third linear drive 83 is used to drive the bed board module D to flip relative to the bed board module C.

[0059] In the folding electric bed of the utility model, the horizontal reference frame 5 can provide a stable platform for the bed board module. The bearing seat 4 is arranged on the horizontal reference frame 5, and the bearing seat 4 is the main load-bearing structure of the bed board module. The bed board module includes five bed board modules 1 distributed in sequence, and two adjacent bed board modules 1 are hinged to each other through the pin 2. The five bed board modules 1 are used to support the user's head, back, buttocks, thighs and legs and feet respectively, wherein the bed board module C is arranged on the bearing seat 4 and is in a horizontal state, and the remaining bed board modules 1 can be adjusted to a preset inclination angle according to user needs. One end of the transmission rod 6 is hinged to the bearing seat 4 and the other end is hinged to the bed board module E; in this way, when the bed board module D is flipped relative to the bed board module C, the inclination angle of the bed board module E relative to the horizontal reference frame 5 also changes. The driving system 8 includes three linear actuators (e.g. electric push rods), namely, the first linear actuator 81 is used to drive the bed board module A to flip relative to the bed board module B, the second linear actuator 82 is used to drive the bed board module B to flip relative to the bed board module C, and the third linear actuator 83 is used to drive the bed board module D to flip relative to the bed board module C. With such an arrangement, the user can adjust the bed board module A, the bed board module B, the bed board module D and the bed board module E to the most comfortable supine angle for the user.

[0060] The folding electric bed of the utility model has the following specific technical effects:

[0061] First, it solves the pain points of the product transportation process: the electric beds currently sold on the market are relatively bulky and are separated from the mattress. Even if they are integrated with the mattress, they are not conducive to transportation. The logistics cost of carrying them upstairs to the customer's home is expensive. The overall structure of the folding electric bed of the utility model is simpler and lighter than the traditional structure, and the bed board module is easy to disassemble and assemble and can be better integrated with the mattress.

[0062] Second, it solves the pain points of large production investment, low efficiency and high labor costs: the existing electric beds sold on the market need to be manually assembled after welding the iron frames, and the production process is relatively complicated; the production process of the folding electric bed of the utility model is easier, and the horizontal reference frame, bearing seat and bed board module of the folding electric bed can realize fully automated production of the production line.

[0063] Third, it solves the pain point of environmental protection: the iron frames of electric beds currently sold on the market are basically made of spraying and plastic spraying processes, which will be harmful to the human body; most of the parts of the folding electric bed of the utility model (such as the bed board module) are more suitable for using aluminum alloy. If the folding electric bed uses aluminum alloy (possibly all aluminum alloy, or a combination of aluminum alloy and steel, depending on the later sample strength test), there is no need for plastic spraying, which will not affect the health of the user.

[0064] Fourth, it solves the pain point of product aesthetics: the existing electric beds sold on the market directly place mattresses, which affects the appearance; after the bed board module and mattress of the folding electric bed of the utility model are integrated together, it is more beautiful.

[0065] Fifth, solve the problem of product improvement purchase: some consumers have already bought bed frames at home, and the existing electric beds need to be placed inside the bed frames. Some bed frames are made of solid wood and have storage boxes, etc., which are not conducive to the installation of existing electric beds; the folding electric bed of the utility model can be directly placed on any bed frame through the horizontal reference frame 5, which is convenient for users to install.

[0066] Sixth, solve the problem of product comfort: the mattress is directly placed on the electric bed currently sold on the market, and the mattress cannot fit the existing electric bed, and the ups and downs of the mattress deviate from the existing electric bed, and the comfort is relatively poor; after the bed board module and the mattress of the folding electric bed of the utility model are integrated together, the mattress will completely follow the ups and downs of the bed board module, improving the user's supine comfort. In the specific production, the five bed board modules 1 of the bed board module are all embedded in the bottom part of the existing mattress.

[0067] Therefore, compared with the traditional structure of existing electric beds, the folding electric bed of the utility model is simpler and lighter, easier to disassemble and assemble, and can be better integrated with the existing mattress. The bed board module has a variety of lying angles that make the user comfortable, and the overall structure is simpler and has better load-bearing capacity, which is especially suitable for home scenarios.

[0068] Further, such as Figure 2 As shown, in order to further simplify the structure of the horizontal reference frame 5, the horizontal reference frame 5 includes a plurality of mutually parallel horizontal beams 51. Specifically, the number of the bearing seats 4 is at least two, wherein two bearing seats 4 are correspondingly arranged on two horizontal beams 51.

[0069] Further, such as Figure 2 , Figure 4 as well as Figure 7 As shown, in order to enable the bed board module to be laid flat into a platform, the folding electric bed also includes a plurality of leg structures 3, a portion of the leg structures 3 are arranged at the bottom of the bed board module B, and the remaining leg structures 3 are arranged at the bottom of the bed board module E, and all the leg structures 3 are in contact with the horizontal reference frame 5 when the five bed board modules 1 are in a horizontal coplanar state. Furthermore, the leg structures 3 are trapezoidal structures to improve the support strength.

[0070] Furthermore, in order to facilitate the disassembly and assembly of the folding electric bed, the support base 4 is fixedly connected to the horizontal reference frame 5 and the bed board module C respectively through pins.

[0071] Further, such as Figures 3 to 8As shown, in order to simplify the structure of the bed board module 1 and facilitate disassembly and assembly, the bed board module 1 includes a panel 11 and a plug-in frame 12, and the plug-in frame 12 is fixedly connected to the panel 11 by a pin. Furthermore, the plug-in frame 12 includes a plurality of longitudinal keel rods 121 and at least one transverse keel rod 122, and the longitudinal keel rods 121 and the transverse keel rods 122 are vertically crossed to form a grid shape.

[0072] Furthermore, in order to improve the connection strength between the bearing seat 4 and the bed board module C, the bearing seat 4 has a through hole that allows the transverse keel rod 122 to vertically penetrate.

[0073] Further, such as Figure 2 As shown, the two ends of the first linear drive 81 are respectively hinged to the bed board module A and the bed board module B, the two ends of the second linear drive 82 are respectively hinged to the bed board module B and the supporting seat 4, and the two ends of the third linear drive 83 are respectively hinged to the supporting seat 4 and the bed board module D.

[0074] Further, in order to improve the installation strength of the drive system 8, the folding electric bed also includes a plurality of articulated brackets 7, which are respectively arranged on the bed board module A, the bed board module B and the bed board module D, and the articulated brackets 7 are used to articulate one of the first linear drive 81, the second linear drive 82 and the third linear drive 83. Specifically, the number of the bearing seats 4 is three and they are respectively recorded as bearing seat A, bearing seat B and bearing seat C, wherein the bearing seat A and the bearing seat B are symmetrically arranged on both sides of the bed board module C in the width direction, and the bearing seat C is arranged in the middle of the bed board module C. The two ends of the first linear drive 81 are respectively articulated to the bed board module A and the bed board module B through the articulated brackets 7; one end of the second linear drive 82 is articulated to the bed board module B through the articulated brackets 7, and the other end is directly articulated to the bearing seat C; one end of the third linear drive 83 is articulated to the bed board module D through the articulated brackets 7, and the other end is directly articulated to the bearing seat C.

[0075] See more specifically Figures 3 to 8 In order to make the bed board module suitable for the electric bed more convenient to disassemble and assemble, convenient for transportation and packaging, save welding tooling, and more integrated with the existing mattress (for example, the bed board module can be better embedded in the bottom of the existing mattress), the utility model also provides a bed board module suitable for the electric bed, including:

[0076] Panel 11, panel 11 is used to support the user's body parts (i.e. the user's head, back, buttocks, thighs, legs and feet);

[0077] The plug-in frame 12 is arranged at the bottom of the panel 11. The plug-in frame 12 includes a plurality of longitudinal keel rods 121 and at least one transverse keel rod 122. All longitudinal keel rods 121 and transverse keel rods 122 are vertically crossed to form a grid shape. The longitudinal keel rods 121 or the transverse keel rods 122 are provided with plug-in holes 123 for the transverse keel rods 122 or the longitudinal keel rods 121 to cross and pass through; at least one end of the longitudinal keel rod 121 is provided with a pin shaft hole 124;

[0078] The longitudinal keel rod 121 and the transverse keel rod 122 are both fixedly connected to the panel 11 via pins. The pins are existing structures with small sizes and are not shown in the figure.

[0079] In the present invention, the plug-in frame 12 includes a plurality of longitudinal keel rods 121 and at least one transverse keel rod 122, and the longitudinal keel rods 121 and the transverse keel rods 122 are assembled by a plug-in structure, that is, the longitudinal keel rods 121 or the transverse keel rods 122 are provided with plug-in holes 123, so that the transverse keel rods 122 or the longitudinal keel rods 121 cross and finally cross vertically into a grid shape, so that it is convenient for the staff to quickly complete the disassembly and assembly and transportation and packaging operations of the plug-in frame 12 like splicing building blocks, and the rigidity of the overall structure of the plug-in frame 12 is more reliable. Another important point is that the longitudinal keel rods 121 and the panel 11 are fixedly connected to each other by a non-welding method, and the transverse keel rods 122 and the panel 11 are fixedly connected to each other by a non-welding method, that is, the longitudinal keel rods 121 and the transverse keel rods 122 are fixedly connected to the panel 11 by pins, so that welding tooling can be omitted, the process difficulty is reduced, and the production cost is reduced.

[0080] Therefore, the bed board module suitable for an electric bed of the utility model can facilitate the staff to quickly complete the disassembly and assembly operations, is convenient for transportation and packaging, eliminates the need for welding tooling, reduces process difficulty, reduces production costs, and the rigidity of the overall structure is more reliable.

[0081] Furthermore, the staff can select the type of the pin according to the requirements, and the pin is a bolt, a screw or a rivet.

[0082] Further, such as Figure 4 , Figure 5 , Figure 6 as well as Figure 7 As shown, in order to reduce material as much as possible, when the human body part is one of the back, buttocks, thighs and legs, the number of the transverse keel rods 122 is also multiple, which can be two or three; when the human body part is the head, the number of the transverse keel rods 122 is one.

[0083] Furthermore, the panel 11 and the transverse keel rod 122 are made of aluminum alloy, which can make the overall weight of the bed board module smaller and facilitate transportation, thereby achieving lightweight.

[0084] Furthermore, the longitudinal keel rod 121 is made of aluminum alloy or steel. When the longitudinal keel rod 121 is made of aluminum alloy, the overall weight of the bed board module can be reduced, which is convenient for transportation, thereby achieving lightweight. When the longitudinal keel rod 121 is made of steel, the overall rigidity of the bed board module can be improved.

[0085] Furthermore, in order to improve the rigidity of the longitudinal keel rod 121 , the longitudinal keel rod 121 is in a U-shaped groove shape.

[0086] Furthermore, in order to improve the rigidity of the plug-in frame 12, the longitudinal keel rod 121 includes a top wall portion 121a and two side wall portions 121b, the plug-in hole 123 is opened on the two side wall portions 121b, and the upper and lower surfaces of the top wall portion 121a are respectively in contact with the panel 11 and the transverse keel rod 122.

[0087] Furthermore, in order to use existing profiles and prevent the transverse keel rod 122 from rotating relative to the longitudinal keel rod 121, the transverse keel rod 122 is made of a tubular profile with a rectangular cross section.

[0088] like Fig. 9 and Fig.10 As shown, the utility model also provides a bed board module suitable for an electric bed, comprising at least two bed board modules, the ends of the longitudinal keel rods 121 of two adjacent bed board modules 1 are opposite, and a pin 2 is passed through the pin hole 124 of the longitudinal keel rod 121, so that the two adjacent bed board modules 1 are hinged together. The bed board module of the utility model can facilitate the staff to quickly complete the disassembly and assembly operations, is convenient for transportation and packaging, saves welding tools, reduces the process difficulty, reduces the production cost, and the rigidity of the overall structure is more reliable.

[0089] In summary, the bed board module and bed board module assembly of the utility model applicable to the electric bed can facilitate the staff to quickly complete the disassembly and assembly operations, facilitate transportation and packaging, save welding tools, reduce process difficulty, reduce production costs, and the rigidity of the overall structure is more reliable. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
