[0002] The adjustable mattress market has grown rapidly in recent years, especially in the smart home sector. For people with special needs, such as the elderly or patients with chronic back pain, personalized support is needed to help improve their quality of life.

[0003] Existing adjustable mattresses have installed lumbar support devices, but due to their unreasonable structural design, the lumbar support is unstable or too expensive, making it difficult to popularize. Furthermore, when installed on an adjustable mattress, it can only support the lumbar spine at one angle, failing to meet the needs of supporting the lumbar spine at different angles.

[0004] Therefore, this utility model is proposed. Utility Model Content

[0005] To address the aforementioned technical problems in the prior art, the purpose of this utility model is to provide a single-motor lumbar support device and its mattress. It uses a single drive motor to achieve smooth lifting and lowering of the lumbar support device, which is stable in use and low in cost. It can also provide lumbar support at any lifting position, achieving more precise support. This not only improves comfort but also allows users to flexibly adjust the shape of the mattress according to their own needs, making it especially suitable for people who need additional lumbar support.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution:

Detailed Implementation

[0025] The present invention will be further described below with reference to specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0026] like Figure 1-4 As shown, the single-motor lumbar support device 1 of this utility model includes a bed frame connecting plate 11, a drive motor 12 is provided on the bed frame connecting plate 11, the drive motor 12 is installed in the motor mounting slot 20, the drive motor 12 has an output end 13, a worm gear 131 is provided in the output end 13, a transmission rod 14 is fixed in the worm gear 131, and both ends of the transmission rod 14 pass through the worm gear 131. The drive motor 12 is provided with a worm 121, and the worm gear 131 meshes with the worm 121.

[0027] Both ends of the transmission rod 14 are provided with lifting components 15. The lifting components 15 include a lead screw 151. The end of the transmission rod 14 is provided with a first transmission gear 152, and the end of the lead screw 151 is provided with a second transmission gear 153. The first transmission gear 152 and the second transmission gear 153 mesh with each other, and the first transmission gear 152 and the second transmission gear 153 are provided with a housing 154 on their exterior.

[0028] The upper end of the lifting assembly 15 is provided with a connecting plate 110, which is installed below the top and waist support plate 16, meaning the lifting assembly 15 is connected to the top and waist support plate 16 through the connecting plate 110. A threaded sleeve 17 is installed below the bed frame connecting plate 11, and threaded sleeve mounting parts 19 are installed on both sides of the threaded sleeve 17, which are fixed to the lower part of the bed frame connecting plate 11. The lower end of the lead screw 151 passes through the bed frame connecting plate 11 and is inserted into the threaded sleeve 17. The threaded sleeve 17 has an internal thread that meshes with the external thread of the lead screw 151, driving the lead screw 151 to move up and down. A limiting retaining ring 18 is provided at the lower end of the lead screw 151, located below the threaded sleeve 17.

[0029] In use, after the drive motor 12 is working, the worm gear 121 rotates, driving the worm wheel 131 to rotate, which in turn drives the transmission rod 14 to rotate. The transmission gear 152 at both ends of the transmission rod 14 rotates with the transmission rod 14, driving the transmission gear 153 to rotate, thereby driving the lead screw 151 to move up and down within the bed frame connecting plate 11. One end of the lead screw 151 is fixed to the top and waist support plate 16 through the lifting assembly 15 and the connecting plate 110, and the other end is equipped with a limit ring 18. When the lead screw 151 moves up and down, it drives the top and waist support plate 16 to move up and down, performing the waist support function. At the same time, the limit ring 18 at the other end can prevent the lead screw 151 from leaving the range of motion.

[0030] To enhance user comfort, this invention incorporates a vibration massage motor 111 mounted on the side of the connecting plate 110, allowing for simultaneous lumbar support and massage. Furthermore, the upper surface of the lumbar support plate 16 is curved and made of glass fiber reinforced nylon, which is more ergonomic and conforms better to the curvature of the human waist. Glass fiber reinforced nylon is a blend of nylon with added glass fiber and toughening agents. As the glass fiber content increases, the tensile and flexural strength of the material can be significantly improved, while impact strength is more complex due to multiple factors. The addition of toughening agents also significantly improves the material's toughness. Optimal comprehensive mechanical properties are achieved when 30%–35% glass fiber and 8%–12% toughening agent are added.

[0031] like Figure 5As shown, the mattress of this utility model includes a bed frame 2 and a single-motor lumbar support device 1. The bed frame 2 is equipped with a first bed board 3, a second bed board 4, a third bed board 5, a fourth bed board 6, and a fifth bed board 7, which are movably connected. The single-motor lumbar support device 1 is installed on the second bed board 4, and is located on the side of the second bed board 4 closest to the third bed board 5. In use, the single-motor lumbar support device 1 supports the lower back. The mattress of this utility model also includes a controller, which can adjust the distance between the lumbar support plate 16 and the second bed board 4, ranging from 4.2 cm to 14.2 cm. The initial distance between the lumbar support plate 16 and the second bed board 4 is preferably 4.2 cm, and the travel provided by the lead screw 151 is preferably 10 cm. Furthermore, the adjustment process will not affect the mattress padding material, nor will it cause damage or breakage. The mattress width can range from 75-180 cm, such as 75cm, 90cm, 100cm, 110cm, 120cm, 150cm, 160cm, 170cm, or 180cm. When the width is too small, the single-motor lumbar support device 1 occupies too large a proportion of the mattress area, which will cause discomfort to the user. When the mattress width is too large, the single-motor lumbar support device 1 occupies too small a proportion of the mattress area, which makes it inconvenient for the user to find the appropriate position of the lumbar support board 16. Therefore, when the mattress width is preferably 75-180cm, the proportion of the single-motor lumbar support device 1 in the mattress area is the most moderate, and the lumbar support board 16 is located right at the user's waist after lying down, making it very convenient to use.

[0032] This utility model uses a single drive motor 12 to achieve smooth lifting and lowering of the single-motor lumbar support device 1, which is stable and low in cost. It can also achieve lumbar support function at any lifting position, achieving more precise support, which not only improves comfort, but also allows users to flexibly adjust the shape of the mattress according to their own needs, making it especially suitable for people who need extra lumbar support.

[0033] In addition, the single-motor lumbar support device 1 in this utility model can also be applied to electric chairs, electric beds or electric chairs. When the back is bent at any angle, the height of the top lumbar support plate 16 can be adjusted at any time. The purpose is to make different lumbar vertebrae (such as lumbar vertebrae changes in different age groups, individual differences in lumbar vertebrae curvature, etc.) fit completely with the mattress, effectively support the waist, and avoid the lumbar spine being suspended and thus causing various discomforts.

[0034] The above embodiments are only used to explain the inventive concept of this utility model, and are not intended to limit the protection of this utility model. Any non-substantial modifications made to this utility model using this concept should fall within the protection scope of this utility model.
