[0002] In recent years, with the continuous improvement of living standards, outdoor sports have gradually transformed from a niche hobby into a popular leisure activity. Outdoor air mattresses, as an indispensable piece of equipment for activities such as camping and picnics, play a crucial role in ensuring the comfort of users. Their performance, such as softness, support, and portability, directly affects the quality of the user's outdoor experience. To a certain extent, a high-quality outdoor air mattress can create a "mobile comfort space" for outdoor enthusiasts, greatly enhancing the quality of outdoor life.

[0003] However, existing outdoor air mattresses have the following shortcomings in actual use: Currently, the main function of outdoor air mattresses on the market is to provide comfortable sleep support, possessing only the function of a single mattress. When users in outdoor environments have needs for sitting or relaxing in addition to resting and sleeping, existing air mattresses cannot meet these needs. For example, in camping scenarios, people who want to sit together to chat or eat can only sit on the ground or carry extra chairs, which is both inconvenient and increases the burden of travel. This limitation of function greatly restricts the usage scenarios and user experience of outdoor air mattresses, failing to meet the diverse and personalized needs of users. In view of this, the multifunctional air mattress proposed in this application is proposed. Utility Model Content

[0046] like Figures 1 to 7 As shown, in one embodiment, a multifunctional air mattress 1 includes an inflatable gas 10 and a support assembly 20. The inflatable gas 10 includes a first air mattress 11, a second air mattress 12, and a third air mattress 13. One edge of the first air mattress 11 is fused to one edge of the second air mattress 12, allowing the first air mattress 11 to rotate about the edge fused to the second air mattress 12. One edge of the third air mattress 13 is fused to the edge of the second air mattress 12 furthest from the first air mattress 11, allowing the third air mattress 13 to rotate about the edge fused to the second air mattress 12. The first air mattress 11, the second air mattress 12, and the third air mattress 13 are parallel to each other to form the mattress body. The support assembly 20 includes a crossbar 21 and several support members 22. The crossbar 21 passes through the first air mattress 11, and each support member 22 passes through the crossbar 21 and is equidistantly distributed. Each support member 22 includes a insert rod. 221, a swing rod 222, a telescopic rod 223, a support rod 224, and a retaining ring 225. The insert rod 221 is mounted on the crossbar 21. One end of the swing rod 222 is rotatably connected to the insert rod 221. The telescopic rod 223 is slidably mounted on the swing rod 222. The telescopic rod 223 has several slots 2231 along its axial direction. The retaining ring 225 is rotatably mounted on the end of the swing rod 222 away from the insert rod 221. The retaining ring 225 engages with any one of the slots 2231, so that the extension length of the telescopic rod 223 relative to the swing rod 222 is adjustable. One end of the support rod 224 is rotatably mounted on the insert rod 221, and the other end of the support rod 224 is engaged with the swing rod 222. There is an angle between the swing rod 222 and the insert rod 221, so that the telescopic rod 223 slides out relative to the swing rod 222 to support the first air cushion 11, so that there is an angle between the first air cushion 11 and the second air cushion 12.

[0047] It should be noted that the first air cushion 11, the second air cushion 12, and the third air cushion 13 are all inflatable structures. The two opposing edges of the upper surface of the second air cushion 12 are respectively fused to one edge of the upper surface of the first air cushion 11 and the third air cushion 13, so that the first air cushion 11 and the third air cushion 13 can rotate about the edge fused to the second air cushion 12 as the axis, thereby allowing the upper surface of the second air cushion 12 to have an angle with the upper surface of the first air cushion 11 / third air cushion 13, or allowing the upper surface of the second air cushion 12 to fit against the upper surface of one of the first air cushions 11 / third air cushions 13.

[0048] like Figures 1 to 4 As shown, in one embodiment, the first air cushion 11 has a first perforation, which extends laterally through both ends of the first air cushion 11, and the crossbar 21 passes through the first perforation.

[0049] It should be noted that the first perforation passes through both ends of the opposite short sides of the first air cushion 11, and the crossbar 21 passes through the first perforation. Multiple first perforations are provided, and the first perforations are parallel to each other and spaced apart.

[0050] like Figure 2 , Figure 4 As shown, in one embodiment, the first air cushion 11 is further provided with a plurality of embedding grooves 112, each embedding groove 112 being vertically connected to the first through hole, each insert rod 221 being located in each embedding groove 112, and each insert rod 221 being connected to the crossbar 21.

[0051] It should be noted that each embedding groove 112 extends from one end of the opposite long side of the first air cushion 11 to the other end, and each embedding groove 112 is perpendicularly connected to each first through hole. The embedding grooves 112 are parallel to each other and spaced apart. Furthermore, multiple crossbars 21 are provided, each crossbar 21 is located in each first air cushion 11, and each support member 22 is parallel to each other and spaced apart. Each support member 22 is perpendicular to each crossbar 21, and each support member 22 is screwed to each crossbar 21. In this way, each support member 22 and each crossbar 21 together form a structure similar to a "well" shape.

[0052] It should be noted that the support member 22 includes an insert rod 221, a swing rod 222, a telescopic rod 223, a support rod 224, and a retaining ring 225. The insert rod 221 includes a rod body 2211 and a connecting block 2212. Two screw holes are provided on the rod body 2211, both located at one end of the rod body 2211 and spaced apart along the axial direction of the rod body 2211. When the rod body 2211 is located within the embedding groove 112, the two screw holes are located on the end of the rod body 2211 furthest from the fusion point between the first air cushion 11 and the second air cushion 12. One end of the connecting block 2212 is vertically screwed to the two screw holes, so that the connecting block 2212 is perpendicular to the rod body 2211. Furthermore, one end of the swing rod 222 is rotatably connected to the end of the connecting block 2212 furthest from the two ends of the rod body 2211, allowing the swing rod 222 to swing relative to the rod body 2211 around the connecting block 2212. Thus, when the rod 2211 is located in the embedded groove 112 and screwed to the crossbar 21, the swing arm 222 swings relative to the rod 2211 with the connecting block 2212 as the center to extend from the first air cushion 11, thereby forming an angle between the swing arm 222 and the bottom surface of the first air cushion 11.

[0053] It should be noted that an annular groove is provided on the end of the rocker arm 222 away from the connecting block 2212. The annular groove is provided along the circumference of the rocker arm 222. One end of the retaining ring 225 is engaged with the annular groove so that the retaining ring 225 can rotate around the axis of the rocker arm 222. Furthermore, two flat portions 2251 are provided on the inner wall of the other end of the retaining ring 225, and the two flat portions 2251 are arranged opposite to each other on the inner wall of the retaining ring 225. Furthermore, a telescopic groove is provided on the end of the rocker arm 222 away from the connecting block 2212. The telescopic groove extends inward from one end of the rocker arm 222 to the end of the rocker arm 222 near the connecting block 2212. It should be noted that two limiting portions 2221 are provided on the inner wall of the telescopic groove, and the two limiting portions 2221 are arranged opposite to each other, and the two limiting portions 2221 are adapted to the two flat portions 2251 on the retaining ring 225. Furthermore, two abutment portions 2232 are provided on the outer wall of the telescopic rod 223. Both abutment portions 2232 extend from one end of the telescopic rod 223 to the other end along the axial direction of the telescopic rod 223, and the two abutment portions 2232 are arranged opposite to each other. The abutment portions 2232 are adapted to the flat portion 2251 and the limiting portion 2221. In this way, when one end of the telescopic rod 223 slides through the retaining ring 225 into the telescopic groove, the abutment portions 2232 on both sides of the telescopic rod 223 abut against the two flat portions 2251 and the two limiting portions 2221 respectively, thereby making the telescopic rod 223 only able to slide along the axial direction of the swing rod 222, and unable to rotate relative to the swing rod 222.

[0054] like Figures 2 to 9As shown, in one embodiment, each slot 2231 is connected to the abutment portion 2232. When the retaining ring 225 is rotated by an external force, the flat portion 2251 is positioned in any slot 2231, thereby making the extension length of the telescopic rod 223 adjustable.

[0055] It should be noted that several slots 2231 are also provided on the outer wall of the telescopic rod 223. Each slot 2231 is opposite to the other and is located between two abutment portions 2232. Each opposite slot 2231 corresponds to the other. This results in several slots 2231 being provided on both sides of each abutment portion 2232. Furthermore, each abutment portion 2232 communicates with several slots 2231 on one side, and each abutment portion 2232 communicates with several slots 2231 on the other side. When the telescopic rod 223 slides within the telescopic groove, when the telescopic rod 223 aligns the two oppositely positioned slots 2231 with the two planes, the retaining ring 225 rotates around the axis of the swing rod 222, causing the two abutment portions 2232 to rotate from the two abutment portions 2232 of the telescopic rod 223 into the two slots 2231 of the telescopic rod 223. This allows the telescopic rod 223 to slide relative to the swing rod 222, thereby making the extension length of the telescopic rod 223 relative to the swing rod 222 adjustable. When there is an angle between the first air cushion 11 and the second air cushion 12, the swing rod 222 is swung to create an angle between the swing rod 222 and the insertion rod 221. At the same time, the telescopic rod 223 is slid out from the swing rod 222 to a suitable length so that the end of the telescopic rod 223 away from the swing rod 222 abuts against the bottom surface. Then, the extension length of the telescopic rod 223 is fixed by rotating the retaining ring 225. In this way, the angle at which the telescopic rod 223 supports the angle between the first air cushion 11 and the second air cushion 12 is adjustable.

[0056] like Figures 10 to 12 As shown, in one embodiment, the support member 22 further includes a locking block 226, which is rotatably disposed on the end of the support rod 224 away from the insertion rod 221, and is used to be inserted into the swing rod 222.

[0057] It should be noted that a cylinder is provided on the side of the rocker arm 222 facing the insertion rod 221, and a slot is formed on the cylinder. An arc-shaped stop block 2222 is provided on the inner wall of the slot. Furthermore, a rod-holding groove 2213 is formed on the side of the insertion rod 221 facing the rocker arm 222, and the rod-holding groove 2213 is formed along the axial direction of the insertion rod 221. One end of the support rod 224 is rotatably disposed at the end of the rod-holding groove 2213 away from the two screw holes, and the other end of the support rod 224 is coaxially provided with a circular groove. One end of the locking block 226 is coaxially provided with a circular protrusion, which is rotatably disposed within the groove, allowing the locking block 226 to rotate coaxially relative to the support rod 224. Furthermore, an arc-shaped locking block 2261 is provided on the end of the locking block 226 away from the circular protrusion. When the support rod 224 drives the locking block 226 to engage with the swing rod 222, the locking block 2261 on the locking block 226 extends into the slot and abuts against the stop block 2222. This causes the support rod 224 to connect the swing rod 222 and the insertion rod 221 respectively. In this way, the support rod 224 fixes the angle between the swing rod 222 and the insertion rod 221, preventing the insertion rod 221 from pushing against one end of the swing rod 222 when the first air cushion 11 is pushed by an external force. This prevents the end of the telescopic rod 223 on the other end of the swing rod 222 from sliding on the bottom surface, which would increase the angle between the swing rod 222 and the first air cushion 11, thus failing to support the first air cushion 11. Furthermore, teeth are provided on the circumferential surface at the middle position of the locking block 226 so that the locking block 226 can better receive external forces. For example, it allows the user to easily grip the locking block 226 so that the user can rotate the locking block 226 to fix the angle between the swing arm 222 and the insertion rod 221.

[0058] like Figures 2 to 3 , Figures 13 to 19 As shown, in one embodiment, the multifunctional air mattress 1 further includes two support components 30, which are rotatably mounted on the third air mattress 13.

[0059] It should be noted that the third air cushion 13 has padding grooves 131 at both ends, and the two supporting components 30 are located in the two padding grooves 131 respectively. Further, the supporting components 30 include a fourth air cushion 31, a support plate 32, a fixing rod 33, and two swinging members 34. The fourth air cushion 31 is an inflatable structure, and a second through hole 311 is formed at both ends of the fourth air cushion 31, with the second through hole 311 penetrating both sides of the long side of the fourth air cushion 31. The fixing rod 33 is located within the second through hole 311. One end of each of the two swinging members 34 passes through the fourth air cushion 31 and is connected to the fixing rod 33. The two swinging members 34 are spaced parallel to each other, and both swinging members 34 are perpendicular to the fixing rod 33. The axial direction of both swinging members 34 is parallel to the lower surface of the third air cushion 13. The end of the swinging member 34 away from the fixing rod 33 is located in the padding groove 131. Furthermore, the ends of both swing members 34 furthest from the fixed rod 33 are rotatably connected to the support plate 32, and the fourth air cushion 31 is fused to the side of the support plate 32 furthest from the swing member 34. Thus, when the swing member 34 drives the fourth air cushion 31 to be parallel to the lower surface of the third air cushion 13, the fourth air cushion 31 and the third air cushion 13 are joined together to form the lower surface of the multifunctional air mattress 1. When the third air cushion 13 rotates around the edge fused with the second air cushion 12, so that the third air cushion 13 is parallel to the second air cushion 12, the swing member 34 drives the fourth air cushion 31 to bulge relative to the lower surface of the third air cushion 13. For example, the swing arm 222 pushes the insert rod 221 to create an angle between the first air cushion 11 and the second air cushion 12, and the third air cushion 13 rotates to be above the second air cushion 12, so that the first air cushion 11, the second air cushion 12, and the third air cushion 13 together form an inflatable air mass 10 that tends towards the sofa. At this time, the swing member 34 can drive the two fourth air cushions 31 to protrude from both ends of the third air cushion 13, so that the two fourth air cushions 31 together form the two armrests of the sofa. In this way, the multifunctional air mattress 1 of this application can not only provide users with a bed to lie down and sleep on, but also provide users with a sofa to sit on, so as to meet the diverse and personalized needs of users.

[0060] like Figures 14 to 19 As shown, in one embodiment, the swing member 34 includes two sleeves 331, two slide rods 332, two elastic members 333, and several rocker arms 334.

[0061] It should be noted that one end of each of the two sleeves 331 is mounted on the fixing rod 33, and the other end of each of the two sleeves 331 is located within the padding groove 131. Furthermore, the end of the sleeve 331 located within the padding groove 131 has a semi-circular structure. A circular groove 3311 and a square groove 3312 are formed on the sleeve 331. The circular groove 3311 is located on the end of the sleeve 331 closest to the fixing rod 33, and the square groove 3312 is located on the semi-circular structure of the sleeve 331. The circular groove 3311 and the square groove 3312 are interconnected, and the diameter of the circular groove 3311 is greater than the diagonal straight-line distance of the square groove 3312. Furthermore, the slide rod 332 has a square structure and slides within the square groove 3312. A circular limiting block 3321 is provided at one end of the slide rod 332, located within the circular groove 3311. The slide rod 332 drives the limiting block 3321 to slide coaxially within the circular groove 3311. Furthermore, because the slide rod 332 has a square structure, it cannot rotate relative to the sleeve 331.

[0062] It should be noted that two rocker arms 334 are rotatably mounted on the ends of the two slide rods 332 away from the limiting block 3321. The ends of each rocker arm 334 away from the slide rod 332 are rotatably connected to the support plate 32, so that each rocker arm 334 on the two slide rods 332 can simultaneously drive the support plate 32 to swing relative to the sleeve 331, thereby causing the support plate 32 to drive the fourth air cushion 31 to protrude relative to the third air cushion 13 to form a handrail. Specifically, an L-shaped groove 3322 is opened on the end of the slide rod 332 away from the limiting block 3321, and one end of each rocker arm 334 is rotatably mounted on an inner side wall of the L-shaped groove 3322. When each rocker arm 334 causes the support plate 32 to swing relative to the slide bar 332 to bulge the fourth air cushion 31, each rocker arm 334 near the limiting block 3321 of the slide bar 332 will abut against the other inner wall of the L-shaped groove 3322, forming a Z-shaped structure between the support plate 32, each rocker arm 334, and the slide bar 332. This allows the fourth air cushion 31 to bulge relative to the third air cushion 13 and move closer to the center of the third air cushion 13. Thus, when the fourth air cushion 31 is subjected to a downward force, the support plate 32 will push each rocker arm 334 closer to the inner wall of the L-shaped groove 3322 near the limiting block 3321, thereby allowing the fourth air cushion 31 to better support the user's arm and improve the user experience. Furthermore, when the fourth air cushion 31 is driven by an external force to move each rocker arm 334 away from the L-shaped groove 3322 and closer to the inner sidewall of the limiting block 3321, each rocker arm 334 is accommodated in the L-shaped groove 3322, and thus each rocker arm 334 is accommodated in the square groove 3312. In this way, the surface of the fourth air cushion 31 can be in the same plane as the lower surface of the third air cushion 13 to form a bed.

[0063] It should be noted that the semi-circular structure of the sleeve 331 is also provided with several clearance grooves 3313. Each clearance groove 3313 is connected to the outer wall of the slide rod 332 and the square groove 3312. When each rocker arm 334 is accommodated in the square groove 3312, the connection position of each support plate 32 is located in the clearance groove 3313, thereby enabling each rocker arm 334 to be in a horizontal state with the slide rod 332, so as to ensure that the surface of the fourth air cushion 31 and the lower surface of the third air cushion 13 are on the same plane.

[0064] It should be noted that the elastic element 333 is a spring structure, and the two elastic elements 333 are respectively located in the two circular grooves 3311. When the support plate 32 drives each rocker arm 334 to approach the end of the sleeve 331 away from the limiting block 3321, each rocker arm 334 can push the slide rod 332 to slide in the direction of the fixed rod 33, thereby causing the slide rod 332 to drive the L-shaped groove 3322 to slide from the square groove 3312 into the circular groove 3311, so that the connection point between one of the rocker arms 334 and the slide rod 332 is located in the circular groove 3311. For example, one end of the L-shaped groove 3322 is connected to the end of the slide rod 332 away from the limiting block 3321, and two rocker arms 334 are rotatably connected to one inner sidewall of the L-shaped groove 3322. The two rocker arms 334 are distributed at intervals along the sliding direction of the slide rod 332, and the two rocker arms 334 have the same structure. When the ends of the two rockers 334 away from the slide bar 332 are close to the ends of the sleeve 331 away from the fixed rod 33, the two rockers 334 can push the slide bar 332 to slide towards the fixed rod 33 to compress the elastic element 333. This causes the slide bar 332 to drive the end of the L-shaped groove 3322 near the limiting block 3321 to extend from the square groove 3312 into the circular groove 3311. The connection point between the rocker 334 near the limiting block 3321 and the L-shaped groove 3322 is located in the circular groove 3311. Furthermore, a supporting part is provided on the end of the sleeve 331 away from the limiting block 3321, and the supporting part is located on the end of the square groove 3312 away from the circular groove 3311. When the two rockers 334 are accommodated in the square groove 3312, the elastic member 333 pushes the sliding rod 332 to drive the end of the rocker 334 away from the limiting block 3321 to abut against the supporting part, so as to prevent the elastic member 333 from pushing the sliding rod 334 to drive the two rockers 334 out of the square groove 3312. This prevents the rocker arm 334 from rotating relative to the slide bar 332, thus preventing the two rocker arms 334 from causing the fourth air cushion 31 to protrude relative to the third air cushion 13 to form an armrest. When one end of one rocker arm 334 is located in the circular groove 3311, the end of the rocker arm 334 connected to the support plate 32 can be engaged in the clearance groove 3313 on the sleeve 331, so that both rocker arms 334 are at the same level as the slide bar 332. This allows the surface of the fourth air cushion 31 to remain at the same level as the lower surface of the third air cushion 13, enabling the user to transform the multi-functional air mattress 1 into a bed for lying down and sleeping. In this way, the user can adjust it according to the usage scenario to meet the diverse and personalized needs.
