Description

Technical Field

[0001] This utility model relates to the field of adjustable mattress technology, and in particular to a pressure-adjustable mattress that combines a spring with an entire airbag. Background Technology

[0002] A mattress is an item placed between the human body and the bed to ensure comfort during sleep. It is typically composed of a combination of materials, and different materials and structural designs directly affect its support, breathability, softness, and other properties. Functionally, a high-quality mattress provides appropriate support, helps maintain the natural physiological curvature of the spine, reduces pressure on various parts of the body, and allows muscles to relax during sleep, thereby improving sleep quality. Traditional mattresses have shortcomings in terms of structure and pressure adjustment. With technological advancements, pressure-adjustable mattresses have been developed, overcoming these traditional deficiencies and enhancing the sleep experience.

[0003] An investigation revealed a Chinese utility model patent (CN213308598U) disclosing a modular mother-and-child mattress. This patent includes a support frame internally divided into a first and a second area. Each area contains a double-layer mattress, consisting of an independent sub-mattress and a mother mattress. These sub-mattresses can be interchanged vertically within the first and second areas. The sub-mattresses and mother mattresses are secured laterally using Velcro. Each sub-mattress is connected to the mother mattress on the same side via multiple evenly distributed connecting straps. A raised piece is fixedly attached to the other side of the sub-mattress, and a hook is movably installed on the other side of the mother mattress to secure the sub-mattress and mother mattress vertically. This utility model divides the mattress into two areas, each consisting of interchangeable sub-mattresses. Children and adults can adjust the mattress type and position according to their individual sleeping habits for better sleep.

[0004] When used by users, the aforementioned patents are prone to misalignment and compression, resulting in a loose overall structure. At the same time, they cause uneven distribution of support, poor local support performance, poor flexibility and precision in pressure adjustment, and inflexible pressure adjustment in different areas along the length of the mattress. They cannot provide customized support according to the needs of different parts of the body, and are prone to causing a stiff feeling during user adjustment, affecting the fit and comfort when lying down.

[0005] Therefore, there is a particular need for a pressure-adjustable mattress that combines springs with a full-length airbag. Utility Model Content

[0006] The purpose of this invention is to provide a pressure-adjustable mattress that combines a spring with an entire airbag, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pressure-adjustable mattress combining a spring and an entire airbag, comprising a mattress body, an upper pad being fitted onto the upper surface of the mattress body, a supporting main pad being fitted onto the inner ring surface of the upper pad, and an adjustment mechanism being installed on the upper surface of the mattress body.

[0008] The adjustment mechanism includes an adjustment airbag assembly, which is installed on the mattress body. A limiting sleeve is fixedly connected to one side of the mattress body, a mounting limiting plate is fixedly connected to one side of the upper pad, a fixing block is fixedly connected to one side of the mounting limiting plate, a nut is fixedly connected to one side of the fixing block, and an adjustment shock-absorbing spring is fixedly connected to the upper surface of the mattress body.

[0009] Preferably, the upper surface of the mattress body has a second mounting opening, and the size of the second mounting opening and the adjustable shock-absorbing spring are matched.

[0010] Preferably, the nut is connected to a fixing block and a mounting limiting plate, and the fixing block is symmetrically arranged with the vertical center line of the nut as the axis of symmetry.

[0011] Preferably, a threaded rod is movably connected to one side of the nut, and the threaded rod is connected to the nut and the fixing block.

[0012] Preferably, a positioning support insert is fixedly connected to the bottom surface of the supporting pad, and the positioning support insert and the second mounting opening are structurally fitted together and in contact with the adjusting damping spring.

[0013] Preferably, the upper surface of the mattress body has a first installation opening, and the size of the first installation opening and the adjustable airbag assembly are matched.

[0014] Preferably, a limiting socket is provided on one side of the limiting sleeve, and the limiting socket and the threaded rod are structurally compatible.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By designing modular spring components and a single airbag arranged vertically or side-by-side, the problem of unreasonable traditional spring and airbag combination structures is solved. The fit between the positioning support insert and the installation opening, the precise installation of the adjustable damping spring, and the stable connection between the limiting sleeve and the threaded rod form a synergistic support system. This system ensures independent elastic support for the spring components while enhancing local support performance with the overall force of the airbag, avoiding uneven support caused by a loose structure.

[0017] 2. By utilizing the mechanical action of inflating and deflating a single airbag, the force applied to the modular spring assembly can be directly altered, allowing the springs to create differentiated pressure at different locations. Compared to the limited adjustment flexibility of traditional mattresses, this design achieves precise pressure control across the mattress's length. Through the dynamic coordination of the airbag and springs, it provides customized support according to the needs of different parts of the body, while the cushioning properties of the springs neutralize the stiffness of the airbag adjustments, significantly improving the fit and comfort when lying down.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a pressure-adjustable mattress that combines a spring and an entire airbag, including a mattress body 1, an upper sleeve 2 that is fitted onto the upper surface of the mattress body 1, a support main pad 4 that is fitted onto the inner ring surface of the upper sleeve 2, and an adjustment mechanism 3 that is installed on the upper surface of the mattress body 1.

[0026] The adjustment mechanism 3 includes an adjustment airbag assembly 302, which is installed on the mattress body 1. A limiting sleeve 305 is fixedly connected to one side of the mattress body 1, and an installation limiting plate 308 is fixedly connected to one side of the upper pad 2. A fixing block 309 is fixedly connected to one side of the installation limiting plate 308, and a nut 310 is fixedly connected to one side of the fixing block 309. An adjustment cushioning spring 304 is fixedly connected to the upper surface of the mattress body 1. When a user needs to use a pressure-adjustable mattress that combines a spring with an entire airbag, the mattress needs to be installed. The mattress body 1 serves as the basic frame, and the adjustment airbag assembly 302 is installed on its upper surface through a first installation opening 301. The adjustment cushioning spring 304 is fixed through a second installation opening 303. The upper pad 2 is limitedly fitted onto the upper surface of the mattress body 1, and the main pad 4 is supported by a positioning support insert 307 at the bottom that fits into the second installation opening 303 and is also adjusted... When the shock-absorbing spring 304 contacts, the main structure assembly is completed. The mounting limiting plate 308 on one side of the upper pad 2 is connected to the nut 310 through the fixing block 309. The threaded rod 311 is passed through the limiting insertion port 306 of the limiting sleeve 305 on one side of the mattress body 1 and tightened with the nut 310 to achieve a stable connection between the upper pad 2 and the mattress body 1. The adjusting airbag assembly 302 in the adjusting mechanism 3 changes its volume by inflating and deflating, generating differentiated forces on the modularly distributed adjusting shock-absorbing springs 304. After the spring assembly is subjected to the force of the airbag, it changes its compression state and transmits the pressure to the human body contact area by supporting the main pad 4, forming a difference in support strength in different areas. When the human body weight acts on the supporting main pad 4, the positioning support insert 307 transmits the pressure to the adjusting shock-absorbing spring 304. The elastic feedback of the spring and the inflation and deflation state of the adjusting airbag assembly 302 work together to adjust the support hardness in real time, ensuring fit and comfort under different body positions.

[0027] Furthermore, a second mounting opening 303 is provided on the upper surface of the mattress body 1, and the second mounting opening 303 and the adjustable shock-absorbing spring 304 are matched in size. The second mounting opening 303 can provide precise installation positioning for the adjustable shock-absorbing spring 304, preventing the spring from shifting or shaking during use, ensuring that the spring provides stable and uniform support to the main mattress 4, and also facilitating the installation, replacement and maintenance of the spring.

[0028] Furthermore, the nut 310 is connected to the mounting limit plate 308 via the fixing block 309, and the fixing block 309 is symmetrically arranged with the vertical center line of the nut 310 as the axis of symmetry. The symmetrically distributed fixing blocks 309 can firmly fix the nut 310 to the mounting limit plate 308, which enhances the connection strength and stability between the nut 310 and the mounting limit plate 308. During the tightening or loosening of the threaded rod 311, it can effectively prevent the nut 310 from tilting or loosening, ensuring the reliability of the connection structure.

[0029] Furthermore, a threaded rod 311 is movably connected to one side of the nut 310, and the threaded rod 311 is connected to the fixing block 309 through the nut 310. The engagement of the threaded rod 311 and the nut 310 enables a detachable connection between the upper cover 2 and the mattress body 1, facilitating the installation, disassembly, and maintenance of various mattress components. At the same time, tightening the threaded rod 311 can adjust the tightness of the connection between the upper cover 2 and the mattress body 1, ensuring the stability of the connection and preventing relative displacement during use.

[0030] Furthermore, a positioning support insert 307 is fixedly connected to the bottom surface of the main support pad 4. The positioning support insert 307 and the second mounting opening 303 are structurally fitted together and contact the adjusting damping spring 304. The positioning support insert 307 fits into the second mounting opening 303, which can accurately position the main support pad 4 and prevent the main support pad 4 from shifting during use. On the other hand, it contacts the adjusting damping spring 304, which can evenly transfer the pressure borne by the main support pad 4 to the adjusting damping spring 304, so that the spring can better play its role in buffering and supporting, and improve the stability and comfort of the support.

[0031] Furthermore, a first installation opening 301 is provided on the upper surface of the mattress body 1, and the size of the first installation opening 301 and the adjustable airbag assembly 302 are matched. The first installation opening 301 provides a dedicated installation space for the adjustable airbag assembly 302, which can ensure that the adjustable airbag assembly 302 is installed in a precise position on the mattress body 1, avoid the airbag being squeezed or rubbed due to improper position during inflation and deflation, ensure the normal operation of the airbag, and also facilitate the installation, maintenance and replacement of the airbag.

[0032] Furthermore, a limiting socket 306 is provided on one side of the limiting sleeve 305, and the limiting socket 306 and the threaded rod 311 are structurally matched. The limiting socket 306 can limit and guide the threaded rod 311, ensuring that it can accurately mate with the nut 310 when the threaded rod 311 passes through. At the same time, after the connection is completed, it can restrict the radial movement of the threaded rod 311, enhance the stability of the connection between the upper sleeve 2 and the mattress body 1, and prevent the threaded rod 311 from shaking.

[0033] Working principle: When a user needs to use a pressure-adjustable mattress that combines springs and an entire airbag, the mattress needs to be installed. The mattress body 1 serves as the basic frame. The upper surface of the mattress body 1 is fitted with the adjustable airbag assembly 302 through the first installation opening 301, and the adjustable shock-absorbing spring 304 is fixed through the second installation opening 303. The upper sleeve 2 is fitted onto the upper surface of the mattress body 1, supporting the main pad 4. The positioning support insert 307 at the bottom fits into the second installation opening 303 and contacts the adjustable shock-absorbing spring 304, completing the assembly of the main structure. The installation limiting plate 308 on one side of the upper sleeve 2 is connected to the nut 310 through the fixing block 309, and the threaded rod 311 passes through the limiting sleeve on one side of the mattress body 1. The limiting insertion port 306 of the plate 305 is tightened with the nut 310 to achieve a stable connection between the upper pad 2 and the mattress body 1. The adjusting airbag assembly 302 in the adjusting mechanism 3 changes its volume by inflating and deflating, generating differentiated forces on the modularly distributed adjusting shock-absorbing springs 304. After the spring assembly is subjected to the force of the airbag, it changes its compression state and transmits the pressure to the human body contact area by supporting the main pad 4, forming a difference in support strength in different areas. When the human body weight acts on the supporting main pad 4, the positioning support insert 307 transmits the pressure to the adjusting shock-absorbing springs 304. The elastic feedback of the spring and the inflation and deflation state of the adjusting airbag assembly 302 work together to adjust the support firmness in real time, ensuring fit and comfort under different body positions.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
