Description

Technical Field

[0001] This invention belongs to the field of health pillow technology, and particularly relates to an adaptive height-adjustable support and the adaptive height-adjustable sleep health pillow composed thereof. Background Technology

[0002] Currently, most neck support pillows on the market have a fixed height or segmented height structure, which cannot dynamically change the support shape of the head and neck with sleeping posture. The human body has significantly different requirements for pillow height and support when sleeping on its back and side: when sleeping on its back, the neck naturally flexes forward, requiring a lower and flat support surface; when sleeping on its side, the width of the shoulders raises the head and neck, requiring higher and more close lateral support. Therefore, traditional fixed-structure pillows cannot meet the physiological curve requirements of both sleeping postures at the same time. Long-term use can easily cause neck muscle tension and uneven force, leading to problems such as stiff neck, neck fatigue, and shoulder and neck pain.

[0003] In response to the above issues, the applicant applied for an invention patent (CN 103330429 B) in 2013, which mainly disclosed a multifunctional sleep health pillow. It is designed with a combination of connecting rods and a reset elastic body to automatically adjust the height of the health pillow according to the change of sleeping posture, which solves the problem that traditional fixed structure pillows cannot meet the physiological curve requirements of two sleeping postures.

[0004] Although the technical solutions in the aforementioned invention patent documents have solved the shortcomings of the existing technology, their overall structure is complex and not conducive to subsequent maintenance. At the same time, they can only achieve overall vertical height adjustment and cannot form a continuous and close-fitting ergonomic support surface with the user's head and neck. They lack the function of dynamic neck support and pressure distribution, making it difficult to truly maintain the physiological curvature of the neck and thus having limited health care effects.

[0005] Based on this, the applicant designed a new type of health pillow with a simple and durable structure. The pillow can automatically adjust its height according to the pressure on the head, the support surface can adapt to the sleeping posture, and the height and support force can be precisely limited. This achieves dynamic neck protection without intervention throughout the entire process, improving sleep comfort and health benefits. Summary of the Invention

[0006] The purpose of this invention is to provide an adaptive height-adjustable support and an adaptive height-adjustable sleep health pillow, which can automatically raise and lower according to the amount of head pressure, the support surface adapts to the sleeping posture, and the height and support force can be precisely limited, achieving dynamic neck protection without intervention throughout the entire process, and improving sleep comfort and health care effects.

[0007] This solution provides an adaptive height-adjustable bracket, which includes a base plate, a compensation extension plate, and a support panel. The compensation extension plate is disposed between the base plate and the support panel. The compensation extension plate is configured to be inclined, with one end hinged to the base plate and the other end hinged to one end of the support panel through a reset elastic member, so as to place the support panel above the base plate. The support panel is configured as a support surface that can switch between an inclined position and a flat position relative to the base plate.

[0008] As the preferred embodiment of this application: Height limiting components are provided between the base plate and the support panel, and between the base plate and the compensation extension plate, respectively. The height and tilt angle of the support panel can be limited by the height limiting components.

[0009] As the preferred embodiment of this application: The height limiting component is a telescopic cylinder or a pull rope or a combination of both. When it is a telescopic cylinder, the size of the support panel is smaller than the size of the base plate. The telescopic cylinder is arranged on both sides of the support panel, with one end hinged to the base plate and the other end hinged to the side of the support panel opposite to the hinge point of the compensation extension plate. When it is a pull rope, multiple sets of pull ropes are provided, which are vertically fixed between the base plate and the support panel, and / or between the base plate and the compensation extension plate.

[0010] As the preferred embodiment of this application: The telescopic cylinder has a rated output force of 10-15N and a compression stroke of at least 7-10cm. The telescopic cylinder provides a buffering force for the support panel during the switching between tilted and flat positions.

[0011] As the preferred embodiment of this application: The width of the compensation plate is 10-12cm, and the angle between it and the base plate is 30-45°.

[0012] As the preferred embodiment of this application: When the support panel is in an inclined position, the height of its higher end from the base plate is 17-19cm, and the height of its lower end from the base plate is 11-13cm.

[0013] As the preferred embodiment of this application: The elastic reset element is a torsion spring or a spring sheet or a combination of both; when it is a torsion spring, it is a single torsion spring or a double torsion spring; when it is a spring sheet, a limiting groove is provided at the corresponding position of at least one of the support panel and the compensation extension plate, and the spring sheet can be snapped into the limiting groove.

[0014] As the preferred embodiment of this application: Ventilation holes are provided on the base plate, the compensation extension plate, and the support panel.

[0015] As the preferred embodiment of this application: The base plate, compensation extension plate, and support panel are all made of aluminum alloy, and their thickness is 1-2cm.

[0016] This solution also provides an adaptive height-adjustable sleep health pillow, comprising a pillow cushion, a pillowcase, and the aforementioned adaptive height-adjustable bracket. The pillow cushion is installed on the support panel of the health pillow bracket to form an ergonomic support surface that conforms to the human head and neck. The pillowcase is fitted over the outside of the health pillow bracket and the pillow cushion.

[0017] Compared with existing technologies, the health pillow with this structure has the following advantages: (1) The adaptive height adjustable bracket of this scheme is composed of three sets of plates with mechanical hinge and elastic reset structure. It has no complicated linkage structure, which improves the stability and durability of use and makes the production and maintenance costs controllable.

[0018] (2) The support panel and the compensation extension plate are hinged and linked, which can not only automatically adjust the up and down displacement according to the pressure of the head and neck, but also adapt to the sleeping posture to ensure that the support surface is continuous and closely fits the physiological curve of the human head and neck, improves the support force for the neck and head, maintains the physiological curvature of the neck, and can relieve shoulder and neck pain and reduce the probability of stiff neck, neck fatigue and chronic strain with long-term use.

[0019] (3) Under the action of the reset elastic element and the hinge, the support panel can automatically and freely switch between the tilted position and the flat position (flat position in contact with the bottom plate) by the pressure of the head and neck. The flat position is adapted to the physiological needs of low neck height and gentle support when lying on the back, and the tilted position matches the high support needs of the shoulder and neck height difference when lying on the side. It can effectively support the head and reduce the pulling on the neck muscles. It can be seen that this solution can adaptively adjust the position of the pillow without intervention during sleep according to the sleeping position, avoiding the shortcomings of traditional fixed height or fixed curved surface pillows.

[0020] (4) The compensation extension plate is inclined between the base plate and the support panel. The compensation extension plate can not only support the support panel, but also compensate for the front and back displacement of the support panel during the lifting or tilting adjustment of the support panel. This keeps the human head and neck in the same support area, avoids the misalignment of the neck force point and passive traction caused by the change in height, fundamentally solves the defects of the pillow in use, such as the forward movement when raised and the backward movement when lowered, and significantly improves the stability of the support.

Detailed Implementation

[0033] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0034] Example 1:

[0035] This embodiment provides an adaptive height-adjustable bracket, such as... Figure 1-3 As shown, it includes a base plate 10, a compensation extension plate, and a support panel 12. The compensation extension plate 11 is disposed between the base plate 10 and the support panel 12. The compensation extension plate 11 is configured to be inclined, with one end hinged to the base plate 10 near one end, and the other end hinged to one end of the support panel 12 through a reset elastic member, thereby forming an approximate "Z" structure. That is, this structure enables the support panel 12 to be mounted above the base plate 10. The support panel 12 is configured as a support surface that can switch between an inclined position and a flat position relative to the base plate 10.

[0036] In this embodiment, the width of the compensation extension plate 11 is preferably 10-12cm, and the included angle between it and the base plate 10 is preferably 30-45°. The compensation extension plate 11 can not only support the support panel 12 to set it above the base plate 10, but also simultaneously compensate for the front and rear displacement of the support panel 12 during the lifting or tilting adjustment, retaining only the vertical displacement, so as to ensure that the support panel 12 is not misaligned during the position switching process.

[0037] Understandably, in this embodiment, the elastic reset force of the reset elastic element can be selected according to actual needs to ensure that it can adaptively switch between tilted and flat positions according to a given external force. In this embodiment, the elastic reset element is preferably a torsion spring 141 or a spring sheet 142 or a combination of both. When it is a torsion spring 141, the torsion spring 141 is a single torsion spring or a double torsion spring, such as... Figure 8-10 As shown, the latter is preferred, employing a double torsion spring. This double torsion spring is integrally formed by two opposing wound spring bodies connected by a central connecting arm, which can provide a balanced restoring torque during bidirectional torsion, avoiding mechanical wear and jamming caused by eccentric loads, and improving the stability of the support action. When it is a spring piece 142, a limiting groove 143 is provided at the corresponding position of at least one of the support panel 12 and the compensation extension plate 11, and the spring piece 142 can be embedded in the limiting groove 143 for limiting and fixing.

[0038] In this embodiment, the hinge between two adjacent plates is formed by a combination of hinge holes 132 and hinge shafts 131 provided on each plate. Figure 3-9 As shown.

[0039] In this embodiment, the adaptive height-adjustable bracket is preferably used in combination with the traditional pillow 17 to form a sleep health pillow. The position of the support panel 12 is adjusted to form an ergonomic support surface that conforms to the human head and neck, thereby achieving effective support for the human neck. In this embodiment, the external force for switching the position of the support panel 12 comes from the pressure of the human head and neck. Of course, this height-adjustable bracket is not limited to sleep health pillows. It can also be used alone or in combination with other structures as a height-adjustable support structure for other applications, such as in the medical rehabilitation field as a head posture adjustment frame for bedridden patients, a rehabilitation nursing frame, and a postoperative leg elevation frame. It can also be used in the automotive supplies field as a support for adjusting the posture of car backrests and seats.

[0040] As a preferred embodiment, height limiting components are provided between the base plate 10 and the support panel 12, and between the base plate 10 and the compensation extension plate 11. These height limiting components can limit the height and tilt angle of the support panel 12. In other words, the height limiting components can preset the initial height and tilt angle of the adjustable bracket, improving adaptability. For example, when used as a sleep health pillow, since the preferences, height, and weight of each user are not exactly the same, the initial height and tilt angle in the tilted position can be adjusted or preset according to the actual situation to meet the needs of different users. It is understood that in actual production and sales, various specifications of sleep health pillows can be prepared through sample analysis for users to choose according to their own situation.

[0041] In this embodiment, the height limiting component is a telescopic cylinder 152 or a pull rope 151 or a combination of both.

[0042] When the pull rope is 151, multiple sets of pull ropes 151 are provided, and are vertically fixed between the base plate 10 and the support panel 12, and / or between the base plate 10 and the compensation extension plate 11, as shown. Figure 1 and Figure 11 As shown, the pull rope 151 can assist in resetting the elastic element to limit the height and tilt of the support panel 12.

[0043] When the telescopic cylinder 152 is used, the size of the support panel 12 is smaller than that of the base plate 10. The telescopic cylinder 152 is located on both sides of the support panel 12, with one end hinged to the base plate 10 and the other end hinged to the side of the support panel 12 opposite to the hinge point 13 of the compensating extension plate 11. Figure 2 and Figure 3 As shown, the telescopic cylinder can assist the reset elastic element in fixing the support panel 12, and can also provide a buffering force for the support panel 12 during the switching between tilted and flat positions. This avoids the instability caused by the different torques in the previous and subsequent stages of the position switching process when only the reset elastic element is used. In addition, the use of the telescopic cylinder 152 also facilitates the subsequent expansion to intelligence and automation.

[0044] The purpose of setting the telescopic cylinder 152 on both sides of the support panel 12 in this embodiment is to ensure that the support panel 12 and the base plate 10 are directly attached when the flat position is achieved, so as to ensure that the height of the bracket is minimized when the flat position is achieved.

[0045] Understandably, the rated output force of the telescopic cylinder 152 can be selected according to actual needs. For example, when a larger external force is required to complete the switching, a telescopic cylinder 152 with a larger rated output force is selected; when a smaller external force is required to complete the switching, a telescopic cylinder 152 with a smaller rated output force is selected. In this embodiment, when used as a sleep health pillow, the rated output force of the telescopic cylinder 152 is preferably 10-15N, and the compression stroke is at least 7-10cm.

[0046] As a preferred embodiment, the height and tilt angle of the support panel 12 can be selected according to actual needs. In this embodiment, when it is used as a sleep health pillow, the height of its high end from the bottom plate 10 is 17-19cm, and the height of its low end from the bottom plate 10 is 11-13cm, which meets the high support needs of most users when lying on their side due to the height difference between their shoulders and neck.

[0047] As a preferred embodiment, the base plate 10, the compensation extension plate 11, and the support panel 12 are all made of aluminum alloy, and their thickness is 1-2 cm. At the same time, ventilation holes 16 are provided on the base plate 10, the compensation extension plate 11, and the support panel 12. The adjustable bracket with this structure is not only lightweight and stable, but also easy to carry and transport. It is understood that in order to improve the safety of use, it is preferable to wrap the outer edges of the support panel 12 and the base plate 10 with padding to improve the smoothness of the outer edges, avoid wear, and also buffer rigid collisions, thereby improving the comfort and safety of use.

[0048] In summary, the adaptive height-adjustable bracket of this embodiment is composed of three sets of plates connected by mechanical hinges and elastic reset structures. It has no complex linkage structure, which improves the stability and durability of use and makes the production and maintenance costs controllable. In addition, the bracket of this structure can achieve continuous switching between high-position tilting posture and flat posture under the action of external force without manual operation, making it convenient to use.

[0049] Example 2:

[0050] This embodiment also provides an adaptive height-adjustable sleep health pillow, which includes a pillow cushion 17, a pillowcase, and the adaptive height-adjustable bracket described in Embodiment 1 above. The pillow cushion 17 is installed on the support panel 12 of the health pillow bracket to form an ergonomic support surface that conforms to the human head and neck. The pillowcase is fitted over the outside of the health pillow bracket and the pillow cushion 17. Preferably, in this embodiment, a cavity 171 adapted to the support panel 12 is provided at the bottom of the pillow cushion 17, and the support panel 12 is nested within the cavity 171. Figure 11 As shown.

[0051] In practical use, this sleep pillow utilizes a hinged connection between the support panel 12 and the compensation extension plate 11, with a reset elastic element between them. When the user lies on their side, the elevated and tilted support panel 12 provides high-level support to meet the height difference between the shoulder and neck, effectively supporting the head and reducing strain on the neck muscles. When the user changes from a side-lying to a supine position, the combined pressure from the head and neck pushes the support panel 12 to rotate relative to the hinge pin connected to the compensation extension plate 11, overcoming the elastic reset force. This causes the support panel 12 to lower, and simultaneously, the compensation extension plate 11 rotates relative to the hinge pin of the base plate 10 until it contacts the base plate 10, thus bringing the support panel 12 into contact with the base plate 10. This completes the shift to a flat position, satisfying the physiological need for low-height, gentle neck support. During this transition, the compensation effect of the compensation extension plate 11 ensures that the head and neck remain in the same support area, avoiding... This design avoids misalignment and passive traction of the neck's stress points due to changes in height, fundamentally solving the problem of pillows shifting forward when raised and backward when lowered, significantly improving support stability. When the user adjusts to a side-lying position, since the side-lying pillow primarily supports the head (approximately 4 kg), the pressure on the reset elastic element is reduced. The elastic reset element resets, and the support panel 12 returns to its high and tilted position, repeating this cycle. Therefore, this embodiment not only automatically adjusts its vertical displacement according to the pressure on the head and neck, but also adaptively adjusts the support surface without intervention during sleep to ensure a continuous and close fit to the physiological curves of the head and neck. This results in higher adaptability and flexibility, improving support for the neck and head, maintaining the physiological curvature of the neck, reducing traction on neck muscles, and relieving neck and shoulder pain with long-term use, reducing the probability of stiff neck, neck fatigue, and chronic strain.

It should be noted that those skilled in the art can make several improvements without departing from the present invention, and these should also be considered within the scope of protection of the present invention. These improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
