[0037] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0038] Embodiment 1:

[0039] Please refer to Figure 1-Figure 6 An inflatable mattress comprises: an outer frame 1, a mattress body 2, a force sharing mechanism 3 and a support mechanism 4, two mattress bodies 2 are symmetrically arranged on the inner side of the outer frame 1, and the ends of the two mattress bodies 2 close to each other are rotatably connected to the middle part of the outer frame 1, and the force sharing mechanism 3 for preventing patients from forming bedsores due to long-term bed rest is arranged above the mattress body 2, and the support mechanism 4 for facilitating patients to get up is arranged below the mattress body 2;

[0040] Specifically, the force sharing mechanism 3 includes a slide groove 5, a movable plate 7, a sliding sleeve 8, a pad assembly and a position adjustment assembly. A slide groove 5 is opened on the surface of the mattress body 2, a movable plate 7 is arranged above the mattress body 2, and a sliding sleeve 8 is fixedly connected to the mattress body 2 below the movable plate 7 and inside the mattress body 2. The sliding sleeve 8 is slidably connected to the mattress body 2 through the slide groove 5.

[0041] Furthermore, the cushion assembly includes a sheath 6, an electromagnetic valve 9, a Velcro 10 and an inflatable core 13. The sheath 6 is arranged above the movable plate 7. The bottom of the sheath 6 and the surface of the movable plate 7 are fixedly connected with the Velcro 10. The sheath 6 is detachably connected to the movable plate 7 through the Velcro 10. The inside of the sheath 6 is fixedly connected with the inflatable core 13. The inside of the inflatable core 13 is fixedly connected with an electric heater. The inflated gas inside the inflatable core 13 can be heated to a suitable temperature by starting the electric heater. The outside of the inflatable core 13 is fixedly connected with the electromagnetic valve 9, and the electromagnetic valve 9 extends to the outside of the sheath 6.

[0042] Furthermore, in order to improve the durability and comfort of the device, the sheath 6 is made of waterproof fabric, and the surface of the sheath 6 is coated with a skin-friendly coating.

[0043] Furthermore, the position adjustment mechanism includes a first dual-axis motor 11, a gear 12 and a rack 14. The first dual-axis motor 11 is fixedly connected to the bottom of the sliding sleeve 8, and the output ends on both sides of the first dual-axis motor 11 are fixedly connected to the gear 12. The rack 14 is fixedly connected to the inside of the mattress body 2 and at a position corresponding to the gear 12, and the gear 12 is meshingly connected to the rack 14.

[0044] It can be known that when in use, an external inflation device can be connected to the electromagnetic valve 9. The inflation device fills gas into the inflatable core 13 from the electromagnetic valve 9 to lift the sheath 6, and then the expanded inflatable core 13 and the sheath 6 are used to share the force under the patient's body. The electromagnetic valve 9 can be controlled to control the intermittent inflation of different areas, so that the body does not need to turn over, and the sheath 6 and the inflatable core 13 under the body can rise and fall intermittently to reduce the long-term pressure on the local area, especially the sacral coccyx, thereby avoiding the formation of bedsores. The first dual-axis motor 11 can be started according to the patient's body shape and the location of the affected area, thereby driving the gear 12 fixed to the output end of the first dual-axis motor 11 to rotate. Because the gear 12 is meshed with the rack 14 and the rack 14 is fixed to the mattress body 2, the gear 12 rotates and drives the sliding sleeve 8 and the moving plate 7 to move along the direction of the slide groove 5, so that the position of the inflatable core 13 and the sheath 6 changes, which effectively improves the applicability of the device.

[0045] Embodiment 2:

[0046] The air mattress provided in Example 1 is further optimized, specifically, as follows: Figure 7-Figure 8 As shown, further, the support mechanism 4 includes a support spring 15 and a lifting assembly, and a plurality of support springs 15 are arranged below the mattress body 2 , and the plurality of support springs 15 are all fixedly connected to the outer frame 1 .

[0047] Furthermore, the lifting assembly includes a second dual-axis motor 16, a rotating rod 17, an extension rod 18 and a fixed shaft 19. The second dual-axis motor 16 is fixedly connected to the inside of the outer frame 1, and the output ends on both sides of the second dual-axis motor 16 are fixedly connected to the rotating rod 17. The end of the rotating rod 17 away from the second dual-axis motor 16 is rotatably connected to the extension rod 18. The bottom of the mattress body 2 is fixedly connected to the fixed shaft 19, and the end of the extension rod 18 away from the rotating rod 17 is rotatably connected to the fixed shaft 19.

[0048] It can be seen that when the device is in use, when the patient needs to stand up or the upper and lower body needs to be raised, the second dual-axis motor 16 can be started to drive the rotating rod 17 connected to the output end of the second dual-axis motor 16 to rotate. Since one end of the mattress body 2 is rotatably connected to the middle part of the outer frame 1, when the rotating rod 17 rotates, it will drive the extension rod 18 connected to it to rotate and push the mattress body 2 upward, which effectively improves the practicality of the device.

[0049] Embodiment 3:

[0050] The air mattress provided in Example 1 is further optimized, specifically, as follows: Figure 1-Figure 8 As shown, further, a controller 20 is fixedly connected to the outer side of the outer frame 1, and the controller 20 is electrically connected to the electromagnetic valve 9, the first dual-axis motor 11, the second dual-axis motor 16 and the electric heater respectively.

[0051] It can be known that, during use, the electromagnetic valve 9, the first dual-axis motor 11, the second dual-axis motor 16 and the electric heater can be controlled respectively by the controller 20.

[0052] In some implementations of the present embodiment, the controller 20 may use a PCB circuit board and a single-chip microcomputer system. The single-chip microcomputer system may use a 80C51 general-purpose single-chip microcomputer, which has good applicability, low cost, and is simple and convenient to manufacture.
