Description

Technical Field

[0001] The present invention relates to the technical field of furniture products, in particular to bedding. Background Art

[0002] Sleep is crucial to our physical and mental health, and the right pillow height is a key factor in ensuring good sleep quality and maintaining a healthy cervical spine. People don't always maintain a single sleeping position during sleep; instead, they constantly shift positions based on their comfort level, frequently alternating between sleeping on their back and their side.

[0003] Different sleeping positions require different pillow heights. When sleeping on your back, a pillow between 8 and 12 cm is recommended to maintain the normal curvature of the cervical spine. If the pillow is too high, the neck will be suspended in mid-air; if it is too low, the head will tend to tilt back. Both of these situations can cause morning shoulder and neck pain, affecting sleep quality and overall health. For side sleepers, a taller pillow between 12 and 15 cm is recommended to ensure full support from ear to acromion, prevent scoliosis, and maintain the natural shape of the spine.

[0004] Different users have different sleeping habits at different times. However, conventional pillows cannot adjust the height of the pillow and can only be used for a single sleeping position, but cannot adapt to different sleeping positions of users, resulting in poor adaptability. Summary of the Invention

[0005] The purpose of the present invention is to provide a bedding to solve the technical problems in the prior art that the pillow height cannot be adjusted and the adaptability is poor.

[0006] As conceived above, the technical solution adopted by the present invention is:

[0007] A bedding comprising:

[0008] Bedding body;

[0009] A bladder structure is disposed within the bedding body, the bladder structure comprising at least two layers of support bladders from top to bottom, the support bladders forming an annular loop for circulating fluid along their circumference and a non-fluid area surrounded by the annular loop, and a support plate is disposed on the top of the support bladders;

[0010] pump units, the pump units being connected to the support bladders respectively;

[0011] A control unit is configured to drive the pump unit to supply fluid to or release fluid from the balloon structure.

[0012] Preferably, the cross-section of the annular loop along its own radial direction is circular.

[0013] Preferably, at least part of the annular loops are interspersed with strip loops, both ends of the strip loops are connected to the annular loop, and radial cross-sections of the strip loops and the annular loop are circles of the same size.

[0014] Preferably, the relationship between the width of the annular loop in the unexpanded state and the height of the annular loop after expansion is:

[0015] C=πd / 2

[0016] Wherein, C is the width of the annular loop in an unexpanded state, and d is the height of the annular loop after expansion.

[0017] Preferably, the annular loops in at least some of the different support bladders have different widths in the unexpanded state.

[0018] Preferably, the width of the annular loop of at least part of the support sac in the unexpanded state gradually increases from top to bottom.

[0019] Preferably, it further includes an elastic reset structure, which surrounds the outer periphery of the sac structure and is used to apply a contraction pressure from the outside to the inside to the sac structure.

[0020] Preferably, the bedding further comprises a monitoring component, the monitoring component being arranged at the front end of the bedding body and being used to obtain the user's sleeping posture information, the sleeping posture information including side sleeping and supine lying;

[0021] The control unit includes a user interface, which is used to receive user setting information, and the user setting information includes side-lying height information and / or supine height information; the control unit is configured to adjust the height of the sac structure to the side-lying height or supine height in the user setting information according to the sleeping position information.

[0022] Preferably, the monitoring component includes a sleeping position sensor sheet having a plurality of sensing points spaced apart along the length direction of the bedding body. The sleeping position sensor sheet can obtain the sleeping position information of the user based on the pressure conditions of the sensing points.

[0023] Preferably, the pump unit includes a control pump, a control solenoid valve and a discharge solenoid valve. The output end of the control pump is respectively connected to multiple support sacs for inputting fluid into the support sacs. A control solenoid valve is provided between each support sac and the circuit of the control pump. The control solenoid valve is used to control the connection or disconnection of the circuit. Multiple control solenoid valves are connected in parallel to the discharge solenoid valve, and the discharge solenoid valve is used to discharge the fluid in the support sacs.

[0024] Beneficial effects of the present invention:

[0025] The bedding proposed in this invention utilizes at least two layers of support bladders within a bladder structure. When inflated, each layer forms a circumferential fluid loop within it, generating uniform radial support force and ensuring stable vertical expansion of the bladder without lateral deformation. The non-fluid-free regions surrounded by the loops partially secure the upper and lower surfaces of the bladders, preventing fluid from passing through. This non-fluid-free region improves the fluid filling rate of the bladders. Support plates atop each layer of support bladders form a rigid support surface. When a pump unit controls the flow of fluid into the bladders, the corresponding loops expand vertically, raising the support plates to a corresponding height. Conversely, when fluid is released, the support plates steadily descend as the bladders contract, adjusting the height of the bedding. This design principle of independent layered control allows the bedding to be filled and released through the combination of different layers of support bladders, creating a continuously variable multi-level support height. A control unit drives the pump units in real time to supply or release fluid, providing the bedding with highly responsive dynamic adjustment capabilities. When the user wants to adjust their sleeping position, the control unit can instantly control the pump unit to supply or release fluid to the support bladder, adjusting the height of the bedding body to achieve the desired height. This allows the user to adjust the height to suit their current sleeping position at any time, ensuring that no matter which sleeping position the user prefers, they will receive good support during sleep, maintaining the natural shape of the spine, and ensuring sleep quality and physical health.

[0045] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0046] See also Figures 1 to 11 The bedding provided by an embodiment of the present invention includes a bedding body 1, a bladder structure 31, a pump unit 32, and a control unit 23. The bladder structure 31 is disposed within the bedding body 1. The bladder structure 31 includes at least two layers of support bladders 311 from top to bottom. The support bladder 311 forms an annular loop 3111 for circulating fluid along its own circumference, and a non-fluid area 3113 surrounded by the annular loop 3111. A support plate 312 is provided on the top of the support bladder 311. The pump units 32 are respectively connected to the support bladders 311. The control unit 23 is configured to drive the pump units 32 to supply or release fluid to the bladder structure 31.

[0047] The bedding disclosed herein utilizes at least two layers of support bladders 311 within the bladder structure 31. When each layer of support bladders 311 expands, a circumferential fluid loop 3111 is formed within the bladder structure 31. This loop generates uniform radial support force, ensuring stable vertical expansion of the support bladder 311 without lateral deformation. The non-fluid-free regions 3113 enclosed by the loops 3111 secure the upper and lower surfaces of the support bladder 311, preventing fluid from passing through. This non-fluid-free region 3113 improves the fluid filling rate of the support bladder 311. Support plates 312 atop each layer of support bladders 311 form a rigid support surface. When the pump unit 32 controls the delivery of fluid to the support bladder 311, the loops 3111 corresponding to the support bladder 311 expand vertically, raising the support plates 312 to a corresponding height. Conversely, when the fluid is released, the support plates 312 steadily descend as the support bladder 311 contracts, adjusting the height of the bedding body 1. Through the design principle of layered independent control, the bedding body 1 can be charged and discharged through the combination of different levels of support capsules 311 to form a continuously variable multi-level support height. The control unit 23 drives the pump unit 32 in real time to perform fluid supply or release operations, so that the bedding has a highly responsive dynamic adjustment capability. When the user wants to adjust the sleeping position, the control unit 23 can instantly control the pump unit 32 to supply or release fluid to the support capsule 311 to adjust the height of the bedding body 1 to achieve an appropriate height. This bedding allows users to adjust the height to suit their current sleeping position at any time according to actual needs, so as to ensure that no matter what sleeping position the user prefers, they can get good support during sleep, maintain the natural shape of the body's spine, and ensure sleep quality and physical health.

[0048] The upper and lower surface portions of the support capsule 311 in the non-fluid region 3113 can be fixed by pressing, bonding, or the like, which is not limited here.

[0049] The specific structure and working principle of this bedding are described in detail below.

[0050] The bedding body 1 injects or releases fluid into the annular loop 3111 of the multiple support bladders 311 passing through the bladder structure 31, controls the expansion or contraction of the support bladders 311, and changes the volume of the support bladders 311, thereby changing the height of the entire bladder structure 31, and then transmits the fluid to the bedding body 1 through the support plate 312 on the top of the uppermost support bladder 311, finally adjusting the height of the bedding body 1.

[0051] It is worth noting that the fluid can be any type of gas or liquid to achieve the volume change of the support capsule 311. The specific type and material of the fluid are not limited here.

[0052] Specifically, the cross-section of the annular loop 3111 along its own radial direction is circular. The circular cross-section design along the radial direction allows the wall surface of the annular loop 3111 to expand or contract more evenly during the process of injecting or discharging fluid. When the annular loop 3111 is injected with fluid, the circular cross-section helps to distribute the pressure more evenly to the surrounding area, directly acting on the support plate 312 at its top, so that the support plate 312 can obtain uniform and smooth support, and the support force transmitted to the bedding body 1 is also more evenly and comfortably distributed, reducing the risk of localized pressure caused by the irregular shape of the support bladder 311.

[0053] Furthermore, the relationship between the width of the annular loop 3111 in the unexpanded state and the height of the annular loop 3111 after expansion is C = πd / 2, where C is the width of the annular loop 3111 in the unexpanded state, and d is the height of the annular loop 3111 after expansion. This structure avoids the inherent defect that the calculation of the height of the annular loop 3111 after expansion depends on the calculation of the fluid volume. Without the need to precisely control the amount of injected fluid and consider the influence of variables such as temperature and pressure, the adjustment accuracy is difficult to guarantee; this design, through the precise design of structural parameters, makes the width of the annular loop 3111 in the unexpanded state directly determine the height of the lifting annular loop 3111 after expansion. This design mechanism based on geometric dimensions ensures high accuracy and certainty in height adjustment, without the need for complex fluid volume monitoring or compensation algorithms, and improves the reliability of height control.

[0054] Optionally, at least part of the annular loop 3111 is interspersed with a strip loop 3112, and both ends of the strip loop 3112 are connected to the annular loop 3111, and the radial cross-sections of the strip loop 3112 and the annular loop 3111 are circles of the same size. The multiple strip loops 3112 increase the fluid flow channel, making the diffusion of the fluid in the support capsule 311 more uniform. When the pump unit 32 is working, it can make the various parts of the support capsule 311 expand or contract more synchronously, thereby improving the accuracy and consistency of the height adjustment and providing users with a more stable support that meets their needs. On the other hand, since the radial cross-sections of the strip loop 3112 and the annular loop 3111 are circles of the same size, the smoothness and coordination of the flow of fluid between different loops are guaranteed, the pressure loss and resistance difference during the fluid flow process are reduced, and the process of injecting and discharging fluid is smoother and more efficient.

[0055] Optionally, the widths of the annular loops 3111 in at least some of the different support sacs 311 in the unexpanded state are different, so that the pump unit 32 can flexibly activate different combinations of support sacs 311, for example, injecting fluid only into the support sac 311 of a larger-width annular loop 3111, or injecting fluid into the support sacs 311 of multiple smaller-width annular loops 3111 at the same time, or injecting fluid into a combination of support sacs 311 of different annular loops 3111 of large and small widths, thereby covering a wider total height adjustment range with a finer gradient, thereby improving the flexibility of the bedding body 1 in adapting to individual differences of different users and changes in sleeping height requirements.

[0056] Furthermore, the width of the annular loop 3111, which at least partially supports the bladder 311, gradually increases from top to bottom in its unexpanded state. This design conforms to ergonomic principles. The smaller width of the annular loop 3111 in the upper layer supporting the bladder 311 has a smaller range of variation and better fits the smaller force range of the head's first contact with the bedding body 1 when lying on its back or side. This can provide precise local support for the head, reduce head pressure, and improve comfort. The gradually increasing width of the annular loop 3111 in the lower layer can provide a more stable bottom support foundation when the overall height of the supporting bladder 311 changes, allowing the entire bladder structure 31 to maintain good stability during height adjustment and prevent tipping or displacement caused by upper pressure.

[0057] In this embodiment, three layers of support bladders 311 are arranged in sequence from top to bottom, and the widths of the annular loops 3111 of the three layers of support bladders 311 in the unexpanded state are 1 cm, 2 cm and 3 cm respectively. In other embodiments, the number of layers of the support bladder 311 and the width of the annular loop 3111 corresponding to the support bladder 311 in the unexpanded state can be adaptively adjusted according to actual needs, and are not limited here.

[0058] Preferably, the bedding further includes an elastic return structure 313, which surrounds the outer periphery of the bladder structure 31 and is used to apply contraction pressure from the outside inward to the bladder structure 31. On the one hand, placing the elastic return structure 313 on the outer periphery of the bladder structure 31 effectively secures the support bladder 311 and support plate 312, enhancing the stability of the overall structure and preventing them from shifting during use, which could affect the normal function of the bedding body 1. On the other hand, when the support bladder 311 is elevated due to the injection of fluid, the elastic return structure 313 correspondingly stretches, storing elastic potential energy. When the fluid is expelled from the support bladder 311, the elastic return structure 313 correspondingly contracts, utilizing this stored potential energy, applying contraction pressure from the outside inward to the support bladder 311. This additional pressure accelerates the expulsion of fluid from the support bladder 311, thereby improving the response speed of height adjustment. At the same time, the contraction pressure can ensure that no residual fluid remains after the support bladder 311 discharges the fluid, effectively avoiding height adjustment errors caused by the presence of residual fluid, making height adjustment more accurate.

[0059] The elastic restoring structure 313 may be an elastic belt, an elastic net, etc., which is not limited here.

[0060] In addition, the bedding also includes a monitoring component 2, which is arranged at the front end of the bedding body 1 and is used to obtain the user's sleeping position information, which includes side sleeping and supine sleeping; the control unit 23 includes a user interface 232, which is used to receive user setting information, and the user setting information includes side lying height information and / or supine lying height information; the control unit 23 is configured to adjust the height of the bladder structure 31 to the side lying height or supine lying height in the user setting information according to the sleeping position information.

[0061] The monitoring component 2 is arranged at the front end of the bedding body 1 and establishes a sensory basis for dynamic adjustment by acquiring real-time information about the user's side-lying or supine sleeping position. The user interface 232 configured in the control unit 23 allows for pre-storage of user-set side-lying and supine height values to form an adjustment reference. Subsequently, when the monitoring component 2 recognizes the user's current sleeping position, the control unit 23 immediately activates the pump unit 32, causing the height of the bladder structure 31 to automatically switch to the corresponding preset value based on the adjustment reference. This automatic adjustment mechanism eliminates the need for manual user operation and can automatically complete the support state switching during sleep, ensuring sleep continuity. By intelligently expanding and contracting the various layers of support bladders 311, the bedding body 1 can dynamically and timely adjust its overall support height and shape to the optimal height difference required for different sleeping positions, such as supine and side-lying, providing the user with continuous and appropriate cervical support throughout the sleep cycle, improving sleep comfort and health.

[0062] Specifically, the monitoring component 2 includes a sleeping position sensor 21 with multiple sensing points 22 spaced along the length of the bedding body 1. The sleeping position sensor 21 can obtain the user's sleeping position information based on the pressure applied to the sensing points 22. Because different parts of the human body have different weights and contact areas, the contact points and pressure distribution between the shoulders and neck and the sleeping position sensor 21 will vary depending on the sleeping position, such as supine or side sleeping.

[0063] When a user places their head on the bedding body 1 and falls asleep, their neck and shoulders exert varying pressures on the multiple sensing points 22 spaced along the length of the bedding body 1 on the sleeping position sensor sheet 21 as their sleeping position changes. For example, when a person is in a supine position, the back area is larger, and the shoulder blades are raised, resulting in higher pressure values at the two points. The sensing points 22 will synchronously calculate the position and pressure of the two points, using this pattern to identify the supine sleeping state. When sleeping on their side, the side area of the body is relatively smaller, and the pressure value at the shoulder is higher. Compared to the pressure of sleeping on their back, the pressure points are more concentrated and the value is larger. The sensing points 22 use this pattern to determine that the person is currently sleeping on their side.

[0064] In this embodiment, the control unit 23 is provided with multiple user interfaces 232, which are divided into a back sleep level 1 button, a back sleep level 2 button, a back sleep level 3 button, a back sleep level 4 button, a side sleep level 1 button, a back sleep level 2 button, a back sleep level 3 button, and a back sleep level 4 button. When a user uses the adjustable bedding body 1 for the first time, they can set the basic height levels for side and back sleep according to their needs. Each user interface 232 is provided with an indicator light 233, which can use different colors or different flashing modes to indicate the status of the user interface 232. The control unit 23 also has an on / off button 231 for turning the control unit 23 on or off.

[0065] The pump unit 32 can inject or drain fluid from the support bladders 311 based on the sleeping posture information. Specifically, the pump unit 32 includes a control pump 321, a control solenoid valve 322, and a discharge solenoid valve 323. The output end of the control pump 321 is connected to the multiple support bladders 311, respectively, for injecting fluid into the support bladders 311. A control solenoid valve 322 is provided between each support bladder 311 and the circuit of the control pump 321. The control solenoid valve 322 is used to control whether the circuit is connected or disconnected. The multiple control solenoid valves 322 are connected in parallel to the discharge solenoid valve 323, which is used to drain the fluid from the support bladders 311.

[0066] When the monitoring component 2 obtains sleeping position information indicating that the user is in a supine sleeping position, assuming that the desired height for supine sleeping is set, the control solenoid valves 322 connected to these support bladders 311 will open upon receiving an opening signal after the pump unit 32 receives the sleeping position information, connecting the control pumps 321 to the circuits of the corresponding support bladders 311. The control pumps 321 begin operating, pumping fluid into the corresponding support bladders 311, causing them to expand and thereby raising the height of the bedding body 1 to accommodate the supine sleeping position.

[0067] When the user rolls over and sleeps on their side, the monitoring component 2 transmits the new sleeping position information to the pump unit 32. If the height of the bedding body 1 needs to be lowered at this time, the pump unit 32 first sends a shutdown signal to the control solenoid valves 322 connected to the corresponding support bladders 311, severing the connection between the control pump 321 and these support bladders 311 and preventing further fluid injection. Simultaneously, the discharge solenoid valves 323 receive an open command, opening the passageway. The fluid within the support bladders 311 is discharged through the discharge solenoid valves 323, causing the support bladders 311 to contract and lower the height of the bedding body 1, meeting the required height for side sleeping.

[0068] It can be understood that when the fluid is liquid, the control pump 321 can be a liquid delivery pump such as a gear pump or a centrifugal pump, and when the fluid is gas, the control pump 321 can be an air pump, etc. The selection of the control pump 321 needs to be adaptively rotated according to the properties of the fluid, and is not limited here.

[0069] Optionally, the control pump 321 is equipped with a flexible shock-absorbing member 324. The flexible shock-absorbing member 324 can effectively buffer and absorb the vibration energy generated by the control pump 321 when it is working, reduce the vibration amplitude transmitted to the bedding body 1, and create a quieter and more stable sleeping environment for the user.

[0070] The flexible shock absorbing member 324 may be a rubber shock absorbing pad, a silicone shock absorbing ring, etc., which will not be described in detail here.

[0071] In addition, the pump unit 32 further includes a control box 325 and a PCB board 326. The PCB board 326 is used to control the operation of various components in the pump unit 32. The control pump 321, the control solenoid valve 322, the discharge solenoid valve 323, and the PCB board 326 are all integrated in the control box 325.

[0072] The bedding also includes a first flexible base plate 4 and a second flexible base plate 5. A sleeping position sensing piece 21 is provided at the front end of the first flexible base plate 4. The second flexible base plate 5 is provided on the first flexible base plate 4. A capsule structure 31 is provided on the second flexible base plate 5. Specifically, the capsule structure 31 is provided at the front end of the second flexible base plate 5, that is, on the side close to the sleeping position sensing piece 21. The bedding body 1 is provided on the capsule structure 31 to fit the sleeping posture of the human body, so that the sleeping position sensing piece 21 can sense the user's sleeping posture. The control box 325 is provided at the rear end of the second flexible base plate 5, that is, on the side away from the sleeping position sensing piece 21, so as to avoid affecting the user's sleeping process.

[0073] The first flexible bottom plate 4 and the second flexible bottom plate 5 may be sponge plates, rubber plates, etc., which are not limited here.
