[0002] When relaxing outdoors, you often need to use a recliner or other equipment for temporary sitting or lying down. In addition, when you are indoors, you sometimes need to use a recliner. Recliners are generally large in size, take up space, and are not easy to use. In order to solve the above technical problems of customers, related technologies have developed similar devices such as inflatable recliners (inflatable beds, inflatable sofas). When the inflatable recliner is not in use, the internal air can be released to reduce the volume of the inflatable recliner, making the inflatable recliner easy to store and store. When in use, inflate the inflatable recliner to make it expand, thereby achieving the effect of controlling the inflatable recliner to be fixed and usable.

[0003] Reference Figure 9 The existing inflatable bed includes a backrest 10 and a lying body 20 that are integrally formed. The backrest is suspended. The backrest 10 can be suspended mainly by the tension between the fabrics. On the one hand, it can save materials. On the other hand, because the volume is reduced, the inflation time can also be relatively reduced.

[0004] With respect to the above-mentioned related art, the angle between the backrest portion 10 and the body portion 20 cannot be adjusted. Summary of the invention

[0005] In order to allow the backrest angle of the inflatable bed to be adjusted when in use, the present application provides a combined inflatable bed.

[0006] The present application provides a combined inflatable bed, which adopts the following technical solution: A combined inflatable bed comprises an independently inflatable backrest and a lying body portion, wherein the backrest can be detachably mounted on the lying body portion, a mounting groove is provided at one end of the lying body portion in the length direction, a mounting plate extends from the lower surface of the end of the lying body portion provided with the mounting groove, the vertical cross-section of the backrest is an elliptical structure, the arc surface of the backrest always remains tangent to the mounting plate, the angle between the major axis of the elliptical structure of the backrest and the lower surface of the lying body portion is greater than 90°, and a fixing piece is provided between the lying body portion and the backrest.

[0007] By adopting the above technical solution, the backrest can be freely installed or disassembled according to the needs of the user, which is convenient for carrying and storing. The elliptical backrest provides better support and comfort, is more ergonomic, supports the human waist, and the design with an angle greater than 90° enables the backrest to more effectively support the user's back. The backrest can be installed on the lying body part at different angles, so that the angle of the backrest can be adjusted when the inflatable bed is in use.

[0019] By adopting the above technical solution, the design of the support airbag can enhance the support ability of the mounting plate and prevent the backrest from deforming during installation; at the same time, the setting of the two air nozzles enables the user to conveniently adjust the inflation degree of the support airbag, thereby adjusting the support strength of the backrest.

[0020] Optionally, two filling airbags are provided on the mounting plate. When the backrest is mounted on the lying body part, the two filling airbags clamp the backrest, and the elastic rope loop partially adheres to the filling airbag.

[0021] By adopting the above technical solution, the design of the filling airbag can further increase the stability and tightness between the backrest and the lying body part, preventing the backrest from shaking or falling off during use; the elastic rope loop adhering to the filling airbag also enhances the fixing effect.

[0022] Optionally, after both the filling airbag and the support airbag are inflated, the filling airbag and the support airbag fill the mounting groove.

[0023] By adopting the above technical solution, the filling airbag and the support airbag jointly fill the mounting groove, making the whole structure more compact and stable. This design not only improves the overall stability and durability of the product, but also makes the appearance more beautiful and tidy.

[0024] In summary, the present application includes at least the following beneficial effects: 1.

Detailed implementation manners

[0027] The following will further elaborate on the present application in conjunction with the attached Figures 1-8 drawings.

[0028] The embodiment of the present application discloses a combined inflatable bed. Referring to Figure 1 , a combined inflatable bed includes a separately inflatable backrest 10 and a lying body part 20. After the backrest 10 and the lying body part 20 are filled with gas, the backrest 10 is detachably mounted on the lying body part 20. The lying body part 20 has a rectangular body structure after inflation, and an installation groove 21 is provided at one end in the length direction of the lying body part 20. The installation groove 21 is a concave arc-shaped groove. The vertical cross-section of the backrest 10 after inflation is an elliptical structure, and a part of the arc surface of the backrest 10 can be completely fitted into the installation groove 21. The backrest 10 and the lying body part 20 maintain a specific included angle, and the specific included angle is greater than 90 degrees and less than 180 degrees.

[0029] Since the vertical cross-section of the backrest 10 is an elliptical structure, at least two-thirds of the arc surface of the backrest 10 close to the lying body part 20 is located outside the installation groove 21, which conforms to ergonomics. When the human back leans against the backrest 10, the waist can be strongly supported, so that the backrest 10 can play the role of supporting the human back.

[0030] Referring to Figure 1 and Figure 2, a rigid mounting plate 22 is connected to the lower surface of the lying body part 20. The mounting plate 22 is located below the mounting groove 21, and the mounting plate 22 is joined to the edge of the mounting groove 21. When the backrest 10 is mounted on the lying body part 20, the arc surface of the backrest 10 is tangent to the mounting plate 22, so that the backrest 10 has a support point at any angle, and can stably support the human back. The included angle between the major axis of the elliptical structure of the backrest 10 and the lower surface of the lying body is in the range of 90° - 180°. However, since the mounting groove 21 has an arc surface structure, when different arc surface positions of the backrest 10 are tangent to the mounting plate 22, the backrest 10 may not be completely in contact with the inner wall of the mounting groove 21. A fixing member is provided between the lying body part 20 and the backrest 10.

[0031] Refer to Figure 1 , the fixing member is an elastic rope loop 30 for sleeving the backrest 10. The head and tail ends of the elastic rope loop 30 are fixedly mounted on the mounting plate 22, and the elastic rope loop 30 has a certain width in the radial direction. The elastic rope loop 30 fits on the arc surface of the backrest 10, and the elastic rope changes adaptively according to the arc surface of the backrest 10.

[0032] Refer to Figure 1 and Figure 2 , the backrest 10 is provided with a first positioning strip 40, and the lying body part 20 is provided with a second positioning strip 50. A magic male sticker is fixedly mounted on the first positioning strip 40, and a magic female sticker is fixedly mounted on the second positioning strip 50. The magic male sticker is a furry surface, and the magic female sticker is a burr surface, and the burr surface faces the arc surface of the backrest 10.

[0033] Refer to Figure 1 , when the first positioning strip 40 and the second positioning strip 50 are pasted, the backrest 10 and the lying body part 20 are initially fixed, and then the elastic rope loop 30 is fixedly sleeved on the backrest 10.

[0034] Refer to Figure 3 , in an embodiment, a plurality of first positioning strips 40 are arranged at intervals along the extending direction of the arc surface of the backrest 10. The first positioning strips 40 at different positions are pasted with the second positioning strip 50, and the backrest 10 is tangent to the mounting plate 22 at different angles, so that backrest functions at different angles can be formed.

[0035] Refer to Figure 4 and Figure 5, in one embodiment, mounting rings 11 are installed on the backrest 10. There are two mounting rings 11, and the radial directions of the mounting rings 11 are the same as the radial direction of the elastic cord loop. Both ends of the first positioning strip 40 are connected to the mounting ring 11. The first positioning strip 40 is slidably mounted on the backrest 10 through the mounting ring 11. The first positioning strip 40 is fixedly connected with a connecting ring 41, and the connecting ring 41 is made of hard plastic. The connecting ring 41 is sleeved on the mounting ring 11, and the connecting ring 41 drives the first positioning ring to slide in the circumferential direction of the mounting ring 11. The slidable setting of the first positioning strip 40 can flexibly change the angle of the backrest 10, so that the backrest 10 can be adjusted at more angles.

[0036] Refer to Figure 6 , further, in order to better support the obliquely arranged backrest 10, a support airbag 60 is arranged on the upper surface of the mounting plate 22. The support airbag 60 has two air nozzles (not shown in the figure). When the backrest 10 abuts against the mounting plate 22, the backrest 10 squeezes part of the support airbag 60, and the support airbag 60 is often divided into two parts. The two air nozzles are respectively located at both ends of the support airbag 60. When the support airbag 60 is inflated, both air nozzles are connected to an air inflation pump. The air inflation pump for inflating the support airbag 60 is an external air inflation pump. The two air nozzles enable the divided support airbag 60 to bulge and wrap part of the outer arc surface of the backrest 10. The part of the support airbag 60 close to the mounting groove 21 fills the mounting groove 21, and the mounting groove 21 also has a limiting effect on the support airbag 60. The support airbag 60 can stably support and reinforce the backrest 10, so that the backrest 10 and the lying body part 20 are stably combined.

[0037] Refer to Figure 1 , the backrest 10 can be completely attached to the inner wall of the mounting groove 21 at only one angle. The backrest 10 squeezes part of the support airbag 60, and part of the support airbag 60 is squeezed on the inner wall of the mounting groove 21. After the support airbag 60 is inflated, it is all located outside the mounting groove 21 and plays a role in supporting and wrapping the arc surface of the backrest 10.

[0038] Refer to Figure 7 , more specifically, filling airbags 70 are also arranged at both ends of the mounting plate 22 along the width direction of the lying body part 20. After the filling airbags 70 are inflated, they abut against the opposite sides of the backrest 10. The filling airbags 70 are also sleeved by the elastic cord loop 30, so that the filling airbags 70 can further strengthen the relationship between the backrest 10 and the lying body part 20.

[0039] Refer to Figure 8, the fabrics used for the support airbag 60 and the filling airbag 70 have a certain elasticity. When the backrest 10 leaves the lying body part 20, after the support airbag 60 and the filling airbag 70 are fully inflated, and then sleeved with the elastic rope loop 30 and the filling airbag 70, the support airbag 60 and the filling airbag 70 can also be used as part of the lying body part 20 to lengthen the length of the lying body part 20. The backrest 10 can be used as a backrest or a pillow.

[0040] The implementation principle of a combined inflatable bed according to an embodiment of the present application is as follows: The design of the inflatable bed is based on the concepts of modularization, detachable and adjustable, aiming to provide users with a comfortable and convenient rest solution. Users can choose whether to install the backrest 10 according to their needs, use an air pump to inflate the lying body part 20 and the backrest 10. After determining the inclination angle of the backrest 10, first use the first positioning strip 40 and the second positioning strip 50 to fix the lying body part 20, and then adjust the inflation degree of the support airbag 60 and the filling airbag 70 according to needs; the backrest 10 and the filling airbag 70 are sleeved on the elastic rope loop 30 and fixed on the mounting plate 22. During use, users can adjust the inflation degree of the support airbag 60 at any time according to needs to obtain the best comfort; after use, deflate the lying body part 20 and the backrest 10 and fold them up for easy carrying and storage.

[0041] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
