Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of smart home and ergonomic products, and particularly relates to a headrest capable of automatically and intelligently adjusting support height and support hardness according to the sleep posture of a user. BACKGROUND

[0002] Traditional headrests or pillows mostly use fixed fillers such as sponge, memory foam, down or buckwheat shells. The support height and hardness of these headrests are fixed and cannot adapt to the frequent changes in posture (such as lying flat and lying on one's side) of the user during sleep. When the human body changes from lying flat to lying on one's side, the width of the shoulders will significantly increase the actual height that the head needs to be supported, and a headrest with a fixed height will cause the user's head to tilt and the cervical spine to bend, which can easily cause problems such as cervical discomfort and stiff neck if used for a long time.

[0003] To solve this problem, a small number of height-adjustable headrests have appeared on the market, but most of them are manually filled or adjusted by mechanical structures and cannot achieve non-invasive and automatic adjustment during sleep. Some products have also tried to use air bags or water bags as adjustment media, but due to the strong fluidity of gas and liquid, it is difficult to accurately control and quickly respond, and problems such as unstable support, excessive wrapping, and slow response are likely to occur, resulting in poor comfort and an unsatisfactory user experience.

[0004] Therefore, there is an urgent need in the art for an intelligent headrest that can real-time perceive changes in user posture and quickly, accurately and automatically adjust support performance while maintaining stable support feeling. SUMMARY

[0018] Specifically, by powering on the intelligent control machine 3, the intelligent control machine 3 controls the electromagnetic valve 8, the booster pump 28, the pressure controller 29, the pull cord recorder 30, etc. through processing the pressure signal conducted by the sensor 5, and the high-pressure gas is supplied to the booster support cylinder 9 from the high-pressure tank 25 through the circulation pipe 6 and the electromagnetic valve 8, the booster support cylinder 9 is driven to rise after being boosted, and the supply of gas is stopped when the support pad 7 reaches the required support height of the headrest body 1 when the human body is lying flat or lying on one side, when the support pad 7 needs to be lowered, the booster support cylinder 9 is depressurized, the electromagnetic valve 8 on the supply circulation pipe 6 is closed, and the high-pressure gas in the booster support cylinder 9 flows back to the low-pressure tank 26 through the three-way valve, another electromagnetic valve 8 and the circulation pipe 6, until the booster support cylinder 9 reaches the required lowering height, and another electromagnetic valve 8 is closed, the height of the support pad 7 is stable, and through the above-mentioned process of boosting or depressurizing the gas in the booster support cylinder 9, the function of the booster support device to intelligently adjust the support height of the headrest body 1 is achieved, and the purpose of adjusting the support height and softness of the headrest body 1 required by the user's head at any time is achieved. By arranging the upper cover 10 and the lower cover 11 at the upper and lower ends of the booster support cylinder 9, respectively, the combination and connection of the booster support cylinder 9, the support bottom plate 2 and the support pad 7 are more convenient, the maintenance and repair of the booster support cylinder 9 are facilitated, the control spring 12 is arranged between the upper cover 10 and the lower cover 11, the elastic pull belt 13 is combined and connected with the control spring 12 and the booster support cylinder 9, respectively, the middle part of the booster support cylinder 9 can be prevented from being deformed or folded, the control spring 12 also has a certain auxiliary support effect. The booster support pipe 18 is arranged above the support pad 7, and after the booster support pipe 18 is filled with appropriate booster gas through the circulation pipe 6 and the electromagnetic valve 8, the booster support pipe 18 has a good effect of soft support for the head, which can reduce the use of other materials such as sponge which is easy to deform and pollute, and achieve the more environmentally friendly requirement of the headrest body 1.

[0019] By setting the pull rope positioner 22 and multiple positioning pull ropes 19, the support height of the supporting pad 7 is determined by adjusting the length of the positioning pull rope 19, and the oblique pulling force of the multiple positioning pull ropes 19 on the supporting pad 7 can reduce the left-right or front-back direction shaking when the headrest is used, which is beneficial to improve the comfortable supporting effect of the headrest body 1. When the support height of the supporting pad 7 is positioned, the pressure of the gas supplied into the pressurized supporting cylinder 9 can be adjusted to adjust the soft or hard supporting effect of the headrest body 1. The function of the pull rope positioner 22 is to drive the pneumatic winding wheel 23 to rotate by the high-pressure gas supplied through the circulation pipe 6 and another electromagnetic valve 8, and the pneumatic winding wheel 23 can also be locked by the air pressure valve provided on the pull rope positioner 22. When the supporting pad 7 rises or falls, the pull rope recorder 30 will transmit the moving distance of the positioning pull rope 19 to the intelligent control machine 3 through the connection of the positioning pull rope 19 and the pull rope recorder 30, and the intelligent control machine 3 controls the opening and closing process of multiple electromagnetic valves 8 to achieve the functions of timely controlling the forward or reverse rotation or locking of the pneumatic winding wheel 23. The pressure controller 29 adjusts the pressure of the gas in the high-pressure tank 25 and the low-pressure tank 26 in time through the control of the intelligent control machine 3. After the above-mentioned pressurized supporting device is combined with the intelligent control machine 3, the intelligent adjustment process is achieved, the headrest body 1 has the functions of intelligent adjustment of lifting and soft or hard support, and has a good effect of comfortable support for the head of the user. The headrest structure is simple, pollution-free and noiseless, which is suitable for better rest and sleep of the user, and is more suitable for use by teenagers or the elderly, and has the characteristics of wide adaptability, environmental protection and no pollution.

[0020] The pressurized supporting cylinder is the core of adjusting the overall height of the headrest. It includes at least one vertically arranged pressurized supporting cylinder 9, the upper end of which is connected with the supporting pad 7 through the upper cover 10, and the lower end is connected with the supporting bottom plate 2 through the lower cover 11. The inside of the pressurized supporting cylinder 9 is a cavity, which is connected with the pressure control circulation system through the circulation pipe 6. When high-pressure gas is filled into the inside, the cylinder body expands and elongates, lifts the supporting pad 7, and increases the height of the headrest; when the gas is released, the cylinder body contracts, and the height of the headrest is reduced. In order to ensure that the pressurized supporting cylinder 9 remains straight during the charging and discharging process and prevents the middle part from bending or folding, a control spring 12 is arranged between the upper and lower covers, and the control spring 12 is connected with the cylinder wall of the pressurized supporting cylinder 9 through the elastic pull belt 13, forming a radial constraint.

[0021] The pressurized supporting pipe is used for optimizing the contact comfort of the surface of the headrest. It is composed of flexible pressurized supporting pipes 18 arranged in a coil or array on the upper surface of the supporting pad 7, which is covered by the elastic pillow cover 16. The pressurized supporting pipe 18 is also connected with the pressure control circulation system through the circulation pipe 6. By filling different pressure gases into these pipes, the softness of the top layer of the headrest can be adjusted, so that the touch feeling is more in line with the head contour, and the oppression caused by the hard support is avoided.

[0022] Positioning ropes 19 are used to improve the stability and high accuracy of the headrest shape change. Multiple rollers 21 are arranged on the edge of the support bottom plate 2, and each roller 21 is wound with a positioning rope 19. One end of the positioning rope 19 is connected to the side or bottom of the support pad 7 at an angle, and the other end is connected to an integrated rope positioner 22. The rope positioner 22 contains a pneumatic winding wheel 23 and a rope length recorder 30 inside. The pneumatic winding wheel 23 is driven by gas and is responsible for winding and unwinding the positioning rope 19; the rope length recorder 30 (such as an encoder) accurately measures the extension and contraction length of the rope. By cooperatively controlling the length of multiple positioning ropes 19, the inclination angle and height of the support pad 7 can be fine-tuned to ensure smooth and stable use.

[0023] The intelligent control system is the "brain" of the headrest, including an intelligent control machine 3 (such as a microprocessor MCU) and sensors 5 (such as pressure distribution sensors or thin film pressure sensor arrays) integrated on the upper surface or inside the headrest. The sensors 5 collect real-time pressure signals when the head contacts the headrest, and transmit the data to the intelligent control machine 3. The intelligent control machine has built-in algorithms that determine whether the user is lying flat, lying on the left side, or lying on the right side based on the pressure distribution pattern, and generates corresponding control instructions.

[0024] The pressure control circulation system is the "power source" of the headrest, including a high-pressure tank 25, a low-pressure tank 26, a booster pump 28, and a pressure controller 29. The booster pump 28 is used to pump gas from the low-pressure tank 26 into the high-pressure tank 25 to maintain system pressure. The high-pressure tank 25 is responsible for providing pressurized gas, and the low-pressure tank 26 is responsible for recovering discharged gas. The pressure controller 29 is used to accurately monitor and adjust the pressure of the two gas storage tanks.

[0025] After the user lies down, the head generates pressure on the sensors 5. The intelligent control machine 3 receives the pressure distribution map from the sensors 5. For example, when the pressure is evenly distributed, it is determined to be lying flat; when the pressure is concentrated on the left side, it is determined to be lying on the left side.

[0026] Scenario A: From lying flat to lying on the left side 1. Signal detection and processing: The sensors 5 detect that the pressure center moves to the left, and the signal is transmitted to the intelligent control machine 3.

[0027] 2. Height adjustment instructions: The intelligent control machine 3 calculates the height that needs to be raised on the left side of the headrest. It first sends instructions to the rope positioner 22 to control the pneumatic winding wheel 23 connected to the left side to appropriately release the positioning rope 19, preparing for the left side to be raised.

[0028] 3. Pressurization execution: The intelligent control machine 3 opens the electromagnetic valve 8 connected to the left pressurization support cylinder 9. High-pressure gas from the high-pressure tank 25 enters the left pressurization support cylinder 9 through the circulation pipe 6 and the opened electromagnetic valve 8. The gas pressure in the cylinder rises, the cylinder body expands axially, and the upper cover 10 and the left side of the support pad 7 move upward.

[0029] 4. Stable control: During this process, the pull rope recorder 30 monitors the moving length of the positioning pull rope 19 in real time and feeds back to the intelligent control machine 3. When the preset height is reached, the intelligent control machine 3 closes the corresponding electromagnetic valve 8 and stops the gas supply. At the same time, the control of the pneumatic winding wheel 23 can be slightly reversed to tighten the positioning pull rope 19, so that the left side of the supporting pad 7 is stably kept at a new height and the shaking is prevented.

[0030] 5. Hardness fine adjustment (optional): At the same time, the intelligent control machine 3 can fill an appropriate amount of gas into the pressurized supporting pipe 18 coiled on the left side of the upper surface of the supporting pad 7, so that it becomes softer and better fits the side of the head.

[0031] Scenario B: Recovery from lateral lying to flat lying 1. The sensor 5 detects that the pressure distribution tends to be uniform.

[0032] 2. The intelligent control machine 3 issues a lowering instruction. It opens the return pipeline electromagnetic valve 8 connected to the left side pressurized supporting cylinder 9, and may control the pneumatic winding wheel 23 to recover the positioning pull rope 19.

[0033] 3. The high-pressure gas in the left side pressurized supporting cylinder 9 is discharged to the low-pressure tank 26 through the circulation pipe 6 and the electromagnetic valve 8. The pressure in the cylinder decreases, and the cylinder body shrinks under the auxiliary contraction force of the control spring 12 and the self-weight action of the supporting pad 7, and the height of the headrest on the left side decreases.

[0034] 4. The pull rope recorder 30 monitors the lowering process, and when the required height for flat lying is reached, the electromagnetic valve 8 is closed, and the adjustment is completed.

[0035] The user can preset the headrest mode through the mobile phone APP or the bedside switch. For example, by selecting the "reading mode", the intelligent control machine 3 controls all the pressurized supporting cylinders 9 to be appropriately inflated, and the overall height of the headrest is raised, so that the user can read comfortably leaning on the bedside. By selecting the "zero pressure mode", the control of the pressurized supporting pipe 18 keeps a lower gas pressure, and an extremely soft wrapping feeling is provided.

[0036] The pressure controller 29 continuously monitors the pressure of the high-pressure tank 25 and the low-pressure tank 26. When the pressure of the high-pressure tank is insufficient, the intelligent control machine 3 starts the pressurizing pump 28 to pump the gas from the low-pressure tank into the high-pressure tank; when the pressure of the low-pressure tank is too high, the system can discharge gas through a safety valve.

[0037] In summary, through the close combination of pneumatic driving and intelligent control, the present application realizes the automatic, precise and personalized adjustment of the headrest supporting performance, and effectively improves the sleep comfort and health level.

Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the present application, and all modifications and equivalents should be included in the scope of the claims of the present application.
