Description

Technical Field

[0001] The present invention relates to the technical field of bedding, and in particular to a support unit, a bed body and an intelligent bed. Background Art

[0002] The bed body is the main part of the bed, which is usually placed on the ground and used to support objects such as mattresses, bedding, etc. The bed body in the prior art is usually made of wood or metal, for example, made by splicing wooden boards, or using an iron frame as the bed body.

[0003] The bed of the prior art often has the following defects:

[0004] First, due to the high density of wood and iron, the overall mass of the bed is large, and it is inconvenient to carry and move; at the same time, wood and iron are hard, and when you accidentally bump into the bed (such as the corner of the bed) while walking, it is quite painful, and there are certain safety hazards.

[0005] Second, in the prior art, some beds do not have storage functions. Although some beds are high above the ground and some items can be placed under the bed, they are prone to dust accumulation and are not clean enough. Some other beds are equipped with storage compartments, which are usually side-opening, making it difficult to effectively utilize space, and the space of a single storage compartment is small, making it difficult to store some large items such as quilts and mattresses.

[0006] Third, the existing bed body is usually fixed in size. Even if there are two single beds, they cannot be spliced ​​into a double bed because of the difficulty in moving. Even if the splicing is completed, it is difficult to have the aesthetics and comfort of a double bed. For a double bed, it is almost impossible to change it into a single bed, and the flexibility is poor.

[0007] Therefore, it is necessary to improve the prior art to overcome the above defects in the prior art. Summary of the invention

[0017] The first support plate is rectangular, the second outer plate extends downward from three sides of the first support plate, and the side where the second outer plate is not arranged is the long side of the first support plate.

[0018] Furthermore, the flexible porous material is polyester fiber, and the density is greater than or equal to 500 kg / m3, and the wall thickness of the support unit is greater than or equal to 6 mm.

[0019] In a second aspect, the present invention provides a bed body, comprising at least one supporting unit as described in any one of the above items and a bed board supported by the supporting unit.

[0020] Furthermore, the bed body includes two supporting units, the outer contours of the two supporting units are rectangular and the long sides of the two supporting units are in contact with each other.

[0021] Furthermore, the bed body also includes a decorative panel and a bed head, the decorative panel is connected to the end surface of one end of the two supporting units, and the bed body is connected to the end surface of the other end of the two supporting units.

[0043] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0044] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0045] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0046] like Figure 1 and Figure 2 As shown, the present invention proposes a support unit 1, which is used to support a bed board 2 of a bed body. The support unit 1 is used as a unit of the bed body, and a modular design is adopted. The size of the bed body can be changed by splicing multiple support units 1.

[0047] The support unit 1 is a shell structure and is made of a flexible porous material. The flexible porous material has good toughness and is not easy to break. Its microstructure has voids, low density, and lighter weight. The flexible porous material can be, for example, polyester fiber, foam rubber, and foam plastic, and its Young's modulus is greater than or equal to 1GPa to provide reliable support. Preferably, the Young's modulus of the flexible porous material is greater than or equal to 2GPa. Taking polypropylene as an example, its Young's modulus is about 3.8GPa. The modulus will decrease after foaming. By controlling the degree of foaming, the modulus can be controlled above 2GPa.

[0048] As a preferred embodiment, the flexible porous material is polyester fiber (PET). The support unit 1 can be formed by hot pressing polyester fiber through a mold. The pressed polyester fiber board is a porous structure, which has many advantages, such as low density, no large deformation and cracking due to thermal expansion, and good flexibility. Since the fibers are bent and intertwined with each other, they can withstand large deformations, and there is no problem of board breakage, let alone insects and barbs. Traditional wood will break when bent to 45°, while the polyester fiber board will not break even if it is bent to 90°.

[0049] As a preferred embodiment, the density of the polyester fiber is greater than or equal to 500 kg / m 3 The wall thickness of the support unit 1 is greater than or equal to 6 mm. At this time, it has good mechanical properties. After testing, Figure 2When a weight of 100 kg is placed on the bed board 2 of the bed body (for example, a 30 kg deformable mattress and a 70 kg person), the support unit 1 will not be deformed significantly and can reliably bear the weight. Of course, the density of the polyester fiber is not limited to this. For example, a smaller density can be selected and the thickness of the support unit 1 can be increased to ensure its load-bearing capacity. The support unit 1 is not limited to having the same wall thickness. Different parts of the support unit 1 can also be set to different thicknesses to more specifically enhance the mechanical properties of its weak points.

[0050] It can be understood that, on the one hand, the support unit 1 is a shell structure, which is not solid, so it can effectively reduce the overall weight; on the other hand, the density of the flexible porous material is low, which can further reduce the weight of the support unit 1, making it easier to move and carry the support unit 1. In addition, the support unit 1 can be pressed by a mold, which is easy to manufacture, and the integrated structure does not need to be assembled, eliminating cumbersome assembly steps, and its corners are easy to form a rounded structure, with low hardness and higher safety.

[0051] The present invention also proposes a bed body, such as Figures 2 to 13 As shown, it includes the supporting unit 1 mentioned above and a bed board 2 connected to the supporting unit 1.

[0052] When the support unit 1 is in use, it is usually placed on the ground, and the bed board 2 is placed on the support unit 1 and supported by the support unit 1. Specifically, the bed board 2 includes a plurality of ribs 20 arranged at intervals, and the ribs 20 are connected to the support unit 1 and supported by the support unit 1. A mattress, a mattress, etc. can be laid on the bed board 2 to make the bed more comfortable to use. The mattress can be an ordinary mattress, such as a latex mattress, a spring mattress, or a deformable mattress. The deformable mattress can be driven to deform, so that the mattress can switch between various postures.

[0053] As mentioned above, the bed adopts a modular design, which is more flexible. Specifically, the bed can have only one support unit 1, or it can have multiple support units 1 (including two), which are spliced ​​together by multiple support units 1. In this way, the bed can be made larger by adding support units 1, and the bed with multiple support units 1 can be made smaller by reducing support units 1.

[0054] The support unit 1 is in the shape of a cuboid as a whole, and its outer contour is rectangular, and can be spliced ​​by side fitting. Figure 2 As shown, Figure 2The figure shows a bed body of an embodiment of the present invention, which includes a support unit 1, the size of the support unit 1 is: length × width × height = 2000mm × 900mm × 285mm (length, width, height are the dimensions along the X, Y, and Z directions in the figure respectively), and the bed body can be used as a single bed. Figure 3 and Figure 4 As shown, Figure 3 and Figure 4 Another embodiment of the bed is shown, which includes two support units 1. The size of the support unit 1 is also 2000mm×900mm×285mm (length×width×height). By splicing the long sides of the two support units 1 together, a bed of 2000mm×1800mm×285mm (length×width×height) can be obtained. The bed can be used as a double bed. Figure 2 The single bed shown can be made into a double bed. Figure 3 The double bed shown can also be split into two Figure 2 The single bed shown can be easily moved and changed because the supporting unit 1 has a small mass.

[0055] It is understandable that the size of the support unit 1 is not limited to the aforementioned example, and it can be smaller or larger, and the number of support units 1 included in the bed is not limited to one or two.

[0056] like Figure 1 , Figure 5 and Figure 6 As shown, the support unit 1 includes a first support plate 4 located at the top thereof. In some embodiments, the two ends of the rib plate 20 are directly connected to the upper surface of the first support plate 4 and supported by the upper surface of the first support plate 4. In other embodiments, the support unit 1 includes a supporting member 40 protruding downward from the first support plate 4. The rib plate 20 is arranged in the supporting member 40 and supported by the supporting member 40. The supporting member 40 includes a supporting portion 400 supported at the bottom of the rib plate 20 and a side wall portion 401 extending upward from the outer periphery of the supporting portion 400 to be connected to the first support plate 4. The supporting portion 400 and the side wall portion 401 cooperate to form a recess 402 with an opening upward. The rib plate 20 is arranged in the recess 402, and at least the two ends are supported by the supporting member 40. Since the two ends of the rib plate 20 in the length direction can be abutted and limited by the side wall portion 401, its position is more stable. Preferably, the support portion 400 is plate-shaped, with arc transitions between it and the side wall portion 401 and between the side wall portion 401 and the first support plate 4. The rib plate 20 is preferably arched with the middle portion tilted upward, and the middle portion can be set higher than the first support plate 4 or flush with the first support plate 4.

[0057] Preferably, both ends of the rib plate 20 are fixedly connected to the support unit 1, for example, connected to the supporting member 40 or other parts of the support unit 1 by bolts, or for example, a clip that is engaged with the rib plate 20 is provided on the supporting member 40 or other parts of the support unit 1. In this way, the rib plate 20 can not only play a supporting role, but also hold the entire structure to reduce the expansion deformation of the support unit 1.

[0058] In order to make the bed have a storage function, the support unit 1 of the present invention is also provided with a storage cavity 3 which is open upwards, and the bed board 2 is mounted above the opening of the storage cavity 3. The storage cavity 3 has a large space and can easily accommodate quilts, mattresses or other items. Figure 1 Taking the support unit 1 shown as an example, its opening size is 1700mm×650mm. With 100mm of ground clearance (for easy cleaning under the bed), its depth is about 160mm, providing sufficient storage space. Since the bed board 2 and the mattress installed later cover the opening of the storage cavity 3, the storage cavity 3 is relatively closed to the outside world and is easier to keep clean.

[0059] It is understandable that the support unit 1 is not limited to having only one storage cavity 3, and two or more storage cavities 3 may be provided to separate different items, but only one storage cavity 3 is advantageous for accommodating larger items. Preferably, the total opening area of ​​the storage cavity 3 accounts for no less than 50% of the area enclosed by the outer contour of the first support plate 4, and the total opening area of ​​the storage cavity 3 refers to the sum of the opening areas of all storage cavities 3 on the support unit 1. For example, Figure 1 In the support unit 1 shown, the total opening area of ​​the storage cavity 3 accounts for about 58% of the area enclosed by the outer contour of the first support plate 4. Figure 7 In the support unit 1 shown, the total opening area of ​​the storage cavity 3 accounts for about 72% of the area enclosed by the outer contour of the first support plate 4.

[0060] In some embodiments, the multiple ribs 20 are independent of each other, and when installing them on the support unit 1, the ribs 20 need to be installed one by one. In other embodiments, in order to facilitate the removal and placement of the bed board 2, the bed board 2 may also include a connector (not shown) connecting the multiple ribs 20, for example, the ribs 20 located on a single support unit 1 are connected into a whole through a connector. The multiple ribs 20 are connected into a whole through the connector, so that the entire bed board 2 can be lifted at the same time, without the need to remove and place the ribs 20 piece by piece, which is more convenient for taking and placing items in the storage cavity 3. The connector can be, for example, a rod body connected to the ends of the multiple ribs 20, and a rod body can be set at both ends of the multiple ribs 20 to improve the mechanical properties.

[0061] As a preferred embodiment, the support unit 1 includes a bottom plate 30 located below the supporting member 40 and a first outer plate 31 extending upward from the outer periphery of the bottom plate 30 and connected to the supporting portion 400. The first outer plate 31 enclosed around the outer periphery of the bottom plate 30 cooperates with the bottom plate 30 to form a storage cavity 3.

[0062] In some embodiments, the bottom plate 30 can be directly supported on the ground. In other embodiments, the support unit 1 includes a plurality of hollow bed legs 5, which are sealed at the bottom and open at the top, and can be arranged on the first support plate 4 and / or the supporting member 40 and / or the bottom plate 30 so as to provide reliable support. For example, Figure 7 and Figure 8 In the embodiment of the support unit 1 shown, there are four legs 5, two of which are arranged at the two ends of the support portion 400 in the length direction and located on both sides of the storage cavity 3, and the other two legs 5 are arranged at the two ends of the bottom plate 30 in the width direction. Figure 1 and Fig. 9 In the embodiment shown, the first support plate 4 located on one side of the storage cavity 3 has a relatively Figure 7 The width B of the structure is preferably greater than 150 mm, and two bed legs 5 are arranged on the first support plate 4 on this side to provide good support. Figure 3 In the double bed shown, the two bed legs 5 on the first support plate 4 are preferably arranged near the middle of the bed body. Since the force in the middle is often greater, arranging the bed legs 5 near the middle can provide better support.

[0063] It is understandable that, due to the provision of the bed legs 5, the bottom plate 30 may not be in contact with the ground, and a space off the ground is formed between the two, which is convenient for cleaning the bottom of the bed body on the one hand, and on the other hand, it can also prevent water on the ground (such as water leaking in the room or water when mopping the floor) from entering the storage cavity 3 through the bottom plate 30 or the first outer plate 31, thereby damaging the items in the storage cavity 3. In some embodiments, a gasket, such as a silicone or rubber gasket, may be provided at the bottom of the bed legs 5 to prevent the polyester fiber material bed legs 5 from contacting the ground, and to prevent the water on the ground from wetting the bed legs 5, thereby preventing the mechanical properties of the polyester fiber sheet from decreasing.

[0064] As a preferred embodiment, the support unit 1 further includes a second outer plate 42 extending downward from the outer periphery of the first support plate 4. The second outer plate 42 can strengthen the strength of the support unit 1 and improve its supporting performance, and can also be shielded from the outer periphery of the support unit 1 to enhance the aesthetics. Preferably, the height of the second outer plate 42 from the ground is higher than the height of the bottom plate 30 from the ground to prevent the second outer plate 42 from being damaged when cleaning the bottom of the bed.

[0065] The first support plate 4 is rectangular. In a preferred embodiment, Figure 1 and Fig. 9 As shown, the second outer plate 42 completely surrounds the outer periphery of the first support plate 4, and extends downward from the four sides of the first support plate 4. In another preferred embodiment, as Figure 7 and Figure 8 As shown, the second outer plate 42 extends downward from three sides of the first support plate 4, and the side where the second outer plate 42 is not provided is the long side of the first support plate 4. Preferably, Figure 7 and Figure 8 When the support units 1 shown are assembled into a double bed, the long sides of the two support units 1 without the second outer panels 42 are fitted together to make the exterior more beautiful.

[0066] Figure 7 The support unit 1 shown can be Figure 1 The support unit 1 shown is obtained by cutting off part of the material, for example, Figure 1 The right side of the support unit 1 shown is cut off 150 mm to the left along the width direction, so that the size of the support unit 1 changes to 2000 mm×750 mm×285 mm (length×width×height). In this way, the width of the support unit 1 can be changed without changing the size of the storage cavity 3. The size of the double bed after assembly is 2000 mm×1500 mm×285 mm (length×width×height).

[0067] In order to facilitate the storage of the support unit 1, Figure 6 As shown, the cross-sectional dimensions of the side wall portion 401, the first outer plate 31 and the bed foot 5 gradually decrease from top to bottom, wherein the first outer plate 31 and the bed foot 5 are tapered with a larger top and a smaller bottom, and the longitudinal section of the side wall portion 401 is in an arc shape, so that when the support units 1 are stacked, the upper side wall portion 401, the first outer plate 31 and the bed foot 5 can extend into the opening of the corresponding part of the lower support unit 1, thereby saving the space occupied during storage, improving the space utilization rate, and facilitating transportation and storage. Fig.10 The second outer plate 42 is preferably arranged vertically to make the appearance more beautiful and reduce the floor space, and of course, it can also be arranged so that the cross-sectional size gradually decreases from top to bottom to further reduce the overall height of the stacked support units 1.

[0068] As a preferred embodiment, Figures 11 to 13As shown, the bed body also includes a headboard 7 connected to the end surface of one end of the support unit 1, and the headboard 7 can be used for people to rest their backs. The headboard 7 and the support unit 1 can be connected by Velcro or bolt connection, and the two are preferably detachably connected. When the bed body includes two or more support units 1, it is preferred that the headboard 7 is connected to the end surfaces of two or more support units 1 at the same time, and its width is adapted to the width of the bed body, which can increase the firmness between the support units 1 in the width direction and prevent the adjacent support units 1 from separating. Further, a decorative plate 6 can also be provided at the other end of the support unit 1 opposite to the headboard 7, and the decorative plate 6 is connected to the end surfaces of two or more support units 1, which can further increase the firmness between the support units 1 in the width direction, and can block the gap between the adjacent support units 1, thereby enhancing the aesthetics. The decorative plate 6 can be, for example, a polyester fiberboard, a wooden board, or a metal plate (such as an aluminum alloy plate). Of course, in addition to increasing the firmness of the connection between the two support units 1 through the headboard 7 and the decorative panel 6, buckles, Velcro or other structures can also be provided between the two support units 1 to prevent the two adjacent support units 1 from separating.

[0069] The present invention also proposes a smart bed, which includes the support unit mentioned above or the bed body mentioned above, and the smart bed also includes a deformable mattress arranged on the bed board 2, which can be switched between different postures.

[0070] The above are only specific embodiments of the present invention, and any other improvements made based on the concept of the present invention are considered to be within the protection scope of the present invention.
