[0002] By taking advantage of the feature that air permeates everywhere, an inflatable bed can make the human body fit perfectly with the bed when sleeping, and all parts of the human body are evenly stressed, thus overcoming the blood circulation disorder caused by uneven stress of traditional beds. In foreign countries, the air bed is also known as a health bed. The inflatable bed gets rid of the defect of the heaviness of traditional furniture and can be placed indoors or outdoors at will.

[0003] Many inflatable beds on the market are equipped with external pillows on the bed surface. The external pillows are fixed on the bed surface and are only used as pillows for users to lie flat, with single functions. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the existing pillows are fixed on the bed surface and can only be used as pillows for lying flat, with single functions. The utility model provides an inflatable bed, in which the pillows can not only be used for lying flat, but also can be rotated to a set angle and used as backrest pillows.

[0005] To solve the above technical problems, an embodiment of the utility model discloses an inflatable bed, including in the width direction, the inflatable bed includes:

[0006] A bed body, including a bed surface;

[0007] A pillow, including a bottom surface;

[0008] A rotating assembly, including a rotating member and a fixing member, wherein the rotating member is fixedly connected to the pillow, and the fixing member is fixedly connected to the bed surface;

[0009] The rotating member is rotatably connected to the fixing member to enable the inflatable bed to switch between a first state and a second state;

[0010] In the first state, a first included angle is defined between the bottom surface of the pillow and the bed surface of the bed body;

[0011] In the second state, a second included angle is defined between the bottom surface of the pillow and the bed surface of the bed body;

[0012] Wherein, the first included angle is smaller than the second included angle.

[0013] Preferably, the first included angle is 0°; and the second included angle is 90°.

[0014] Preferably, the second included angle is 70° to 130°.

[0015] Preferably, the pillow includes a side surface, and the bottom surface of the pillow is connected to the side surface of the pillow; and the rotating member is fixedly connected to the bottom surface or the side surface of the pillow.

[0016] Preferably, the rotating member includes a plug post; the fixing member includes a plug hole; wherein, the plug post of the rotating member passes through the plug hole of the fixing member to be rotatably connected to the fixing member, and the plug post of the rotating member extends along the width direction of the air bed.

[0017] Preferably, the fixing member further includes: a first base fixedly connected to the bed surface of the bed body; a support portion connected to the first base of the fixing member, and the plug hole of the fixing member penetrates through the support portion of the fixing member along the width direction of the air bed.

[0018] Preferably, the plug post of the rotating member includes a first limiting structure and a plug portion, and the first limiting structure is connected to one end of the plug portion; the plug portion is located in the plug hole of the fixing member; the rotating member further includes a second limiting structure, and the second limiting structure is connected to the other end of the plug portion of the plug post of the rotating member; and the support portion of the fixing member is located between the first limiting structure and the second limiting structure, the first limiting structure abuts against one end of the support portion of the fixing member, and the second limiting structure abuts against the other end of the support portion of the fixing member.

[0019] Preferably, the first limiting structure includes a plurality of connected stepped cylinders, and along the width direction of the air bed and towards the direction of the plug portion, the radial dimension of each stepped cylinder gradually increases; and the maximum radial dimension of the stepped cylinder is greater than the inner diameter of the plug hole of the fixing member.

[0021] Preferably, the air bed includes two such rotating assemblies, and the two rotating assemblies are spaced apart along the width direction of the air bed.

[0022] In this application, the rotating member of the rotating assembly is fixedly connected to the pillow, and the fixing member is fixedly connected to the bed surface. The rotating member and the fixing member are rotatably connected, that is, the bed body and the pillow are rotatably connected, so that the pillow can rotate relative to the bed body. When the pillow rotates relative to the bed body by a set angle (for example, 90°), a second included angle is formed between the bottom surface of the pillow and the bed surface of the bed body. At this time, the inflatable bed is in the second state, and the pillow can lean against the wall. The user can lean back against the pillow and use the pillow as a backrest. Correspondingly, when the pillow does not rotate relative to the bed body, that is, the bed body and the pillow are parallel or substantially parallel at this time, a first included angle (for example, 0°) is formed between the bottom surface of the pillow and the bed surface of the bed body. At this time, the inflatable bed is in the first state, and the pillow can be used for the user to lie flat.

[0023] In summary, this application rotatably connects the pillow and the bed body, thereby providing different usage states of the pillow for the user, such as lying flat and leaning back, and further meeting the different usage needs of the user and improving the user experience.

[0044] To make the purpose, technical solutions, and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the drawings.

[0045] Refer to Figures 1 to 5 , in the description of the present application, the bed body 200 of the inflatable bed 100 includes at least one first wall 210, a second wall 220, and an inflatable chamber 230 for inflating defined by the first wall 210 and the second wall 220. After the pressure of the gas (for example, air) in the inflatable chamber 230 reaches the required value, the bed body 200 is in an inflated state and maintains a preset shape; and when the gas in the inflatable chamber 230 is discharged, the bed body 200 is in a deflated state, and the volume of the bed body 200 is greatly reduced compared to when it is in the inflated state, so as to facilitate the storage of the bed body 200.

[0046] A plurality of tension members are provided in the inflatable chamber 230 of the bed body 200, and the tension members are connected to the first wall 210 and the second wall 220 by high-frequency welding, hot melting, gluing or other connection methods. After the tension members are tensioned, they provide a pulling force to the first wall 210 and the second wall 220 to limit the deformation of the bed body 200, so that the bed body 200 can maintain a preset shape after being inflated.

[0047] Optionally, the plurality of tension members have different structures in different embodiments. For example, each tension member is a sheet-like tension member 241 or a linear tension member 242.

[0048] The sheet-like tension member 241 may have a single-layer or composite-layer structure according to actual needs.

[0049] When the sheet-like tension member 241 is a single-layer sheet material, it may be made of a polymer material, which may include but is not limited to one or more of polyvinyl chloride (PVC), polyurethane (PU), thermoplastic urethanes (TPU), polyethylene terephthalate (PET), ethylene-vinyl acetate (EVA) copolymer, and nylon. It can be understood that in some other embodiments, the main body of the single-layer sheet-like tension member 241 may also be made of other materials other than polymer materials, such as fabric materials, where the fabric materials are optionally finely woven or formed into a mesh structure. The fabric materials may be but are not limited to natural fiber fabrics (e.g., but not limited to, cotton fabrics, linen fabrics, wool fabrics, silk fabrics) or synthetic fiber fabrics (e.g., but not limited to, polyester fiber fabrics, polyethylene fiber fabrics, polypropylene fiber fabrics).

[0050] When the sheet-like tension member 241 is a composite sheet material, it is composed of two or more layers of sheet materials bonded, welded, or otherwise combined, and each layer of the multi-layer sheet materials can be made of the polymer materials or other materials as described above.

[0051] The linear tension member 242 includes one or more wire bodies, and these one or more wire bodies span the distance between the first wall 210 and the second wall 220 of the bed body 200 and are optionally parallel or substantially parallel in space. For example, these wire bodies are spaced apart from each other at equal distances or according to a certain pattern. The material of one or more wire bodies in the linear tension member 242 may be but is not limited to natural fibers (e.g., but not limited to, cotton fibers, linen fibers, wool fibers, silk fibers) or synthetic fibers (e.g., but not limited to, polyester fibers, polyethylene fibers, polypropylene fibers). The linear tension member 242 is usually indirectly connected to the first wall 210 and the second wall 220 through a connecting member, and the connecting member may be made of a polymer material that is not limited to facilitating the welding of the first wall 210 and the second wall 220.

[0052] Reference Figure 5 and Figure 6, an embodiment of the present application provides an inflatable bed 100, including the above-mentioned bed body 200, pillow 300 and rotating assembly 400. Among them, the bed body 200 and the pillow 300 are rotatably connected through the rotating assembly 400. In this way, the pillow 300 can rotate relative to the bed body 200, so that the pillow 300 can not only be placed flat on the first wall 210 (which can also be called the bed surface) of the bed body 200 (as shown in Figure 5 ), for the user to lie flat and rest, but also make the pillow 300 rotate a set angle (for example, 90°, as shown in Figure 6 ), and make the pillow 300 abut against the wall. The user can lean back against the pillow 300 and use the pillow 300 as a backrest.

[0053] Exemplarily, the pillow 300 in this embodiment is an inflatable pillow. However, those skilled in the art can understand that in other embodiments, the pillow 300 can also be an ordinary pillow filled with fillers (such as cotton).

[0054] The following will describe in detail how the bed body 200 and the pillow 300 are rotatably connected through the rotating assembly 400 with reference to the accompanying drawings.

[0055] As shown in Figure 7 and Figure 8 , the above-mentioned rotating assembly 400 includes a rotating member 410 and a fixing member 420; among them, the rotating member 410 is fixedly connected to the pillow 300, and the rotating member 410 includes a plug-in column 411. In this embodiment, the rotating member 410 includes a second base 412, and the second base 412 is high-frequency welded to the bottom surface 301 of the pillow 300 and near the edge of the head of the bed 202. Those skilled in the art can understand that the bottom surface 301 of the pillow 300 refers to the surface that is parallel and in contact with the first wall 210 of the bed body 200 when the pillow 300 is placed flat.

[0056] Optionally, the second base 412 is circular in shape, and it fits and is high-frequency welded to the bottom surface 301 of the pillow 300. Those skilled in the art can understand that in other embodiments, the second base 412 can also be in other shapes, such as rectangular, polygonal, etc. The second base 412 and the bottom surface 301 of the pillow 300 can also adopt other connection methods, such as bonding, etc., and the present application does not limit this.

[0057] In this embodiment, the rotating member 410 is arranged on the bottom surface 301 of the pillow 300. However, those skilled in the art can understand that in other embodiments, the rotating member 410 can be arranged on the side surface 302 of the pillow 300. The side surface 302 refers to the surface connected to the bottom surface 301, and it is also the surface that is in contact with the first wall 210 of the bed body 200 when the pillow 300 is used as a backrest. At this time, the second base 412 of the rotating member 410 is high-frequency welded to the side surface 302 of the pillow 300.

[0058] In this embodiment, the fixing member 420 is fixedly connected to the first wall 210 of the bed body 200, and the fixing member 420 includes a plugging hole 421. In this embodiment, the fixing member 420 includes a first base 422, and the first base 422 is high-frequency welded to a position near the edge of the head 202 of the first wall 210 of the bed body 200.

[0059] Optionally, the first base 422 is circular in shape, and it is attached to and high-frequency welded to the first wall 210 of the bed body 200. Those skilled in the art can understand that in other embodiments, the first base 422 can also be in other shapes, such as rectangular, polygonal, etc. The first base 422 and the first wall 210 can also adopt other connection methods, such as bonding, etc., and the present application does not limit this.

[0060] Reference Figures 8 to 11 As shown, the plugging post 411 is connected to the plugging hole 421 in a rotatable manner around the width direction X of the bed body 200 (i.e., the width direction of the inflatable bed 100), so that the inflatable bed 100 can be switched between a first state and a second state; in the first state, the bottom surface 301 of the pillow 300 and the first wall 210 of the bed body 200 define a first included angle β; in the second state, the bottom surface 301 of the pillow 300 and the first wall 210 of the bed body 200 define a second included angle α; wherein, the first included angle β is smaller than the second included angle α.

[0061] Exemplarily, the plugging post 411 is inserted into the plugging hole 421 along the width direction X of the bed body 200 and can rotate relative to the plugging hole 421, so that the pillow 300 rotates relative to the bed body 200. When the pillow 300 rotates relative to the bed body 200 by 70° to 130°, at this time the inflatable bed 100 is in the second state, that is Figure 6 as shown, the second included angle α formed between the first wall 210 of the bed body 200 and the bottom surface 301 of the pillow 300 is 70° to 130°, and at this time the pillow 300 can be used as a backrest. Optionally, Figure 6 shows a schematic diagram in which the second included angle α formed between the first wall 210 of the bed body 200 and the bottom surface 301 of the pillow 300 is 90°.

[0062] Correspondingly, when the pillow 300 does not rotate relative to the bed body 200, that is, at this time the bed body 200 and the pillow 300 are parallel, the inflatable bed 100 is in the first state, and the first included angle formed between the first wall 210 of the bed body 200 and the bottom surface 301 of the pillow 300 is 0°, and the pillow 300 is placed flat for the user to lie on. Those skilled in the art can understand that in other embodiments, the pillow 300 rotates slightly relative to the bed body 200, such as Figure 11The first included angle β formed between the first wall 210 of the bed body 200 and the bottom surface 301 of the pillow 300 is 5°, 8°, 10°, etc. At this time, the inflatable bed 100 is also in the first state and can still be used by the user to lie flat.

[0063] Optionally, the pillow 300 can rotate relative to the bed body 200 by 0° to 180°. It is easy to understand that when the pillow 300 rotates 90° relative to the bed body 200, that is, the second included angle α formed between the first wall 210 of the bed body 200 and the bottom surface 301 of the pillow 300 is 90°, as Figure 6 shown in the state, at this time the comfort of the user with their back against the pillow 300 is better.

[0064] It should be noted that in the embodiment of the present application, the pillow 300 is placed at a position close to the headboard 202 of the bed body 200, that is, the rotating assembly 400 is also arranged at a position close to the headboard 202, so that the pillow 300 rotates by a set angle, and the pillow 300 can lean against the wall at the headboard 202 or other supportable structures, so as to facilitate the user to lean against the pillow 300. However, those skilled in the art can understand that the pillow 300 can also be placed at other positions of the bed body 200, such as the foot of the bed, both sides in the width direction of the bed body 200, etc.

[0065] Optionally, as Figure 8 shown, the present application is provided with two rotating assemblies 400, and the two rotating assemblies 400 are arranged at intervals along the width direction X of the bed body 200. That is to say, there are two connections between the bed body 200 and the pillow 300, thereby ensuring the reliability of the connection between the bed body 200 and the pillow 300. Those skilled in the art can understand that in other embodiments, other numbers of rotating assemblies 400 can also be set, such as 3, 4, etc.

[0066] Adopting the above technical solution, the rotating member 410 of the rotating assembly 400 is fixedly connected to the pillow 300, the fixing member 420 is fixedly connected to the first wall 210 of the bed body 200, and the insertion column 411 of the rotating member 410 is connected to the insertion hole 421 of the fixing member 420 in a manner that can rotate around the width direction X of the bed body 200. Then the rotating member 410 and the fixing member 420 are rotationally connected, that is, the bed body 200 and the pillow 300 are rotationally connected, so that the insertion column 411 rotates in the insertion hole 421, thereby causing the pillow 300 to rotate relative to the bed body 200. When the pillow 300 rotates by a set angle relative to the bed body 200, the bottom surface 301 of the pillow 300 forms a second included angle α with the first wall 210 of the bed body 200 (for example Figure 6As shown, at 90°), the inflatable bed 100 is in the second state. At this time, the pillow 300 can be abutted against the wall, and the user can lean against the pillow 300 and use the pillow 300 as a backrest. Correspondingly, when the pillow 300 does not rotate relative to the bed body 200 or rotates slightly, that is, when the bed body 200 and the pillow 300 are parallel or substantially parallel, the bottom surface 301 of the pillow 300 forms a first included angle β (such as 0°) with the first wall 210 of the bed body 200. At this time, the inflatable bed 100 is in the first state, and the pillow 300 can be used for the user to lie flat.

[0067] In summary, in the present application, the pillow 300 and the bed body 200 are rotationally connected. On the one hand, the pillow 300 and the bed body 200 are kept connected, which is convenient for the user to use. On the other hand, different usage states of the pillow 300 are provided to the user, such as lying flat and leaning back, so as to meet the different usage needs of the user and improve the user experience.

[0068] Reference Figure 6 and Figure 12 , the fixing member 420 of the rotating assembly 400 includes a supporting portion 423. The supporting portion 423 is connected to the first base 422. The supporting portion 423 is provided with a plugging hole 421, and the plugging hole 421 penetrates through the supporting portion 423 along the width direction X of the bed body 200. Exemplarily, the supporting portion 423 is a plate-like structure with an irregular cross-section, and its cross-sectional shape is a combined figure formed by splicing a trapezoid and a semi-circle located above the trapezoid.

[0069] The supporting portion 423 extends along the height direction Z and is perpendicular to the first base 422, so that the plugging hole 421 provided thereon corresponds to the height of the plugging column 411 on the pillow 300, which is beneficial for the plugging column 411 to be inserted into the plugging hole 421 to realize the rotational connection between the pillow 300 and the bed body 200. However, those skilled in the art can understand that in other embodiments, the supporting portion 423 and the first base 422 may not be perpendicular, that is, the supporting portion 423 and the first base 422 form other angles, such as 80°, 100°, etc.

[0070] Reference Figure 7 , Figure 8 and Figure 13 , the rotating member 410 includes a first limiting structure 413, a plugging portion 415, a second limiting structure 416 and a connecting portion 417 connected in sequence. Among them, the connecting portion 417 is vertically connected to the second limiting structure 416 and the second base 412, and the first limiting structure 413 and the plugging portion 415 jointly define the plugging column 411.

[0071] In the width direction X of the bed body 200, the support portion 423 is located between the first limiting structure 413 and the second limiting structure 416, that is, the support portion 423 is located on the insertion portion 415, and the insertion portion 415 is located in the insertion hole 421. Exemplarily, the length of the insertion portion 415 is equal to the length of the insertion hole 421.

[0072] As Figure 7 and Figure 13 shown, the first limiting structure 413 includes a plurality of connected stepped cylinders 414. Along the width direction X of the bed body 200 and in the direction M towards the insertion portion 415, the radial dimension of each stepped cylinder 414 gradually increases. The maximum radial dimension of the stepped cylinder 414 is greater than the inner diameter of the insertion hole 421. The first end face 418 of the stepped cylinder 414 connected to the insertion portion 415 abuts against the first surface 424 of the support portion 423. Then the first limiting structure 413 cannot easily pass through the insertion hole 421, and the first limiting structure 413 restricts the movement of the support portion 423 along the width direction X of the bed body 200 and in the direction N towards the insertion column 411, thereby forming a one-way limit on the support portion 423 in the direction N.

[0073] Correspondingly, as Figure 12 and Figure 14 shown, the cross-section of the second limiting structure 416 is circular, its outer diameter is greater than the inner diameter of the insertion hole 421, and the second end face 419 of the second limiting structure 416 connected to the insertion portion 415 abuts against the second surface 425 of the support portion 423. That is to say, the second limiting structure 416 cannot pass through the insertion hole 421, and the second limiting structure 416 restricts the movement of the support portion 423 along the width direction X of the bed body 200 and in the direction M away from the insertion column 411, thereby forming a one-way limit on the support portion 423 in the direction M.

[0074] In this embodiment, the second limiting structure 416 is columnar, and its outer diameter is greater than the inner diameter of the insertion hole 421, thereby forming a block on the support portion 423 to achieve a one-way limit in the direction M. However, those skilled in the art can understand that in other embodiments, the cross-section of the second limiting structure 416 can be other shapes, such as rectangular, as long as the cross-sectional area of the second limiting structure 416 is greater than the cross-sectional area of the insertion hole 421, the block on the support portion 423 can be achieved.

[0075] In summary, the support portion 423 is located between the first limiting structure 413 and the second limiting structure 416. The first limiting structure 413 and the second limiting structure 416 form a clamping on the support portion 423 along the width direction X of the bed body 200, thereby preventing the insertion column 411 from detaching during the rotation in the insertion hole 421, and further causing the separation of the pillow 300 and the bed body 200.

[0076] Exemplarily, a plurality of connected stepped cylinders 414 form a serrated outer peripheral surface of the insertion post 411, and the maximum radial dimension of the stepped cylinder 414 is greater than the inner diameter of the insertion hole 421. On the one hand, this forms a limiting effect of the plurality of stepped cylinders 414 on the support portion 423 to prevent the insertion post 411 from slipping out of the insertion hole 421. On the other hand, it increases the friction force. That is, even if the first limiting structure 413 of the insertion post 411 slides into the insertion hole 421, due to the plurality of stepped cylinders 414, the friction force between the insertion post 411 and the inner wall of the insertion hole 421 increases, and the insertion post 411 is not easily detached from the insertion hole 421.

[0077] In this embodiment, a plurality of stepped cylinders 414 are provided to form a limiting effect on the support portion 423. However, those skilled in the art can understand that in other embodiments, other structures can also be provided to achieve the limiting effect on the support portion 423, such as protrusions, etc.

[0078] Optionally, both the rotating member 410 and the fixing member 420 of the rotating assembly 400 are made of PVC (Polyvinylchloride), which has elasticity, so as to facilitate inserting the insertion post 411 into the insertion hole 421 to achieve the rotational connection between the pillow 300 and the bed body 200. Those skilled in the art can understand that in other embodiments, the rotating assembly 400 made of other materials can also be selected, such as TPU (Thermoplastic Polyurethane Elastomer), etc.

[0079] So far, the present application has satisfactorily described the specific structure of the connection between the bed body 200 and the pillow 300 through the rotating assembly 400. The above embodiments achieve the rotational connection between the bed body 200 and the pillow 300, providing different usage states of the pillow 300 to the user, such as lying flat and reclining, thereby meeting the different usage needs of the user and improving the user experience.

[0080] Those skilled in the art can understand that this rotational connection solution for the bed body 200 and the pillow 300 can be applied to almost all types of beds, such as sofa beds, solid wood beds, etc.

[0081] Although the present invention has been illustrated and described by referring to certain preferred embodiments of the present invention, those of ordinary skill in the art should understand that the above content is a further detailed description of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is only limited to these descriptions. Those skilled in the art can make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
