Description

Technical Field

[0001] This utility model belongs to the field of bedding technology, specifically relating to a three-dimensional support pillow. Background Technology

[0002] Currently, pillows on the market are mainly divided into four types: 1. Soft pillows, such as latex pillows, memory foam pillows, 3D pillows, cotton pillows, polyester fiber pillows, etc. 2. Filled pillows, such as water-filled pillows, air-filled pillows, goose down pillows, buckwheat pillows, soft particle pillows, etc. 3. Hard pillows, such as wooden pillows, ceramic pillows, bamboo pillows, etc. 4. Composite material pillows, such as pillows composed of multiple layers of different materials or blocks of different shapes.

[0003] For flexible pillows, all load-bearing parts provide the same level of support. The support they provide depends entirely on the load exerted on the pillow by the object itself. However, the human head, neck, and spine are irregularly shaped and have uneven density. Therefore, when a person's head, neck, and spine rest on such a flexible pillow, the lowest part of the head often experiences the greatest support. This results in the flexible pillow not providing adequate support to the head, neck, and spine during sleep. Conversely, with filled pillows, if the filling is too fluid, the internal filling cannot provide effective and stable support to the head, neck, and spine, offering only weak, soft support that changes with sleeping posture. Conversely, if the filling is too fluid, the internal filling... If the filling cannot move to conform to the contours of the head, neck, and spine, it cannot provide a support surface that conforms more closely to these contours. This results in some areas having stronger support than others, affecting sleep comfort. For hard pillows, due to their high firmness, their shape does not change with head pressure during sleep, providing only surface support to flatter areas or point support to rounder parts of the head, leading to extremely poor sleep comfort. Composite material pillows suffer from similar problems to flexible pillows; their shape is fixed. Evenly applying force to their outer surfaces will not change their shape. For composite and flexible pillows to provide even support for the head, neck, and spine, the contours of the head, neck, and spine need to be similar to or identical to the pillow's design. However, everyone's body shape is different, so these types of pillows cannot provide support that conforms to the contours of the head, neck, and spine for most users. This can lead to serious sleep problems such as neck and shoulder pain, spinal fatigue, and muscle soreness after prolonged sleep, significantly impacting sleep quality. Furthermore, during prolonged sleep, heat can accumulate inside a flexible pillow, causing the temperature in the sleeping area to rise and affecting sleep quality.

[0004] In order to effectively conform to the user's various parts and provide effective support, while effectively dissipating the heat accumulated in the pillow during sleep, a three-dimensional support pillow is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by providing a three-dimensional support pillow. By combining a flexible material layer with a rigid support structure, the pillow allows the user to experience a soft and comfortable skin-like contact during sleep, while simultaneously conforming quickly to the contours of the head, neck, and spine, providing three-dimensional support. This eliminates muscle fatigue and injury caused by insufficient support for the head, neck, and spine during prolonged sleep. The heat dissipation channels on the flexible pillowcase effectively dissipate heat accumulated in the pillow during sleep, preventing oily and sweaty skin on the head and neck due to heat buildup, thus improving sleep comfort.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a three-dimensional support pillow, comprising a pillowcase and a flexible pillowcase wrapped inside the pillowcase, wherein a pillow core and a pillow core cover are provided inside the flexible pillowcase, the pillow core being a flexible material filled inside the pillow core cover, characterized in that a support module cluster is also installed at the lower end of the pillow core cover, the top and sides of the support module cluster being embedded inside the pillow core cover, and the lower end of the pillow core cover being fixedly connected to the bottom surface of the support module cluster;

[0007] The support module cluster includes a base module, a flexible support block located at the center of the base module, and support mechanisms staggered on both sides of the flexible support block. The support mechanism is a unidirectional tilting structure and has a reset function. The support mechanisms located on both sides of the flexible support block move away from the flexible support block respectively.

[0008] The support mechanism includes a support block, a first bearing rotatably connected to the support block, a support rod mounted on the first bearing, a second bearing mounted on the lower end of the support rod, and a limiting connecting block rotatably connected to the second bearing. The upper end of the support block is provided with a spring limiting hole one, the upper and lower ends of the support rod are respectively provided with spring limiting holes two and three, and the lower end of the limiting connecting block is also provided with a spring limiting hole four. A first torsion spring is fitted on the first bearing, with its two ends engaging with spring limiting holes one and two, respectively. A second torsion spring is fitted on the second bearing, with its two ends engaging with spring limiting holes three and four, respectively. The side of the limiting connecting block away from the flexible support block is provided with rounded corners. A reinforcing rib is provided on the side of the support rod closest to the flexible support block, extending from the bottom to the upper middle part to enhance structural strength and blocking the lower end of the support rod to form a one-way limiting, allowing the support mechanism to tilt only towards the side away from the flexible support block. The first and second torsion springs serve as support and reset mechanisms.

[0009] Furthermore, adhesive sections extend inward from the left and right sides of the bottom surface of the pillow core cover, and these adhesive sections are detachably connected to the bottom surface of the support module cluster.

[0010] Furthermore, a support ramp is provided on the side of the base module near the flexible support block.

[0011] Furthermore, protective bends are installed at both ends of the first and second torsion springs to prevent damage to the support block, support rod, limit connecting block, or user.

[0012] Furthermore, the support mechanism is evenly distributed in a cross shape on the base module, and is arranged alternately in the front, back, left and right directions. The distance between the left and right sides of the support mechanism is not less than the width of the support block, and the distance between the front and back sides is not less than the distance from the second bearing to the top surface of the support block.

[0013] Furthermore, the height of the limiting connecting block is the same as the height of the support block, so that when the support rod is subjected to force and fits against the base module, the upper surface of the limiting connecting block and the upper surface of the support block are on the same plane to form support.

[0014] Furthermore, the distance from the outer side of the reinforcing rib to the center of the second bearing is equal to the distance from the top surface of the limiting connecting block to the center of the second bearing, so that when the support rod is subjected to force and fits against the base module, the reinforcing rib and the upper surface of the limiting connecting block are on the same surface to form support.

[0015] Furthermore, the pillow core cover is made of high-strength fiber fabric.

[0016] Furthermore, the included angle between the two ends of the first torsion spring and the second torsion spring is 80°, so that the support block and the support rod, and the limiting connecting block and the base module maintain a 10° tilt angle when no force is applied, ensuring that the support rod will not be stuck in its original position in a vertical state when it is tilted under force.

[0017] The beneficial effects of this utility model are: 1) This utility model conforms to the human body and the support module cluster through the force deformation of the pillow core. The support module cluster provides force support, and the pillow core provides flexible cushioning. When the pillow conforms to the contour of the human body, it improves comfort and softness, eliminates fatigue and damage to the body, and quickly and efficiently conforms to the contour of the head, shoulders, neck and spine of different users during sleep and lying down, providing a three-dimensional support surface and support force, and improving sleep comfort.

[0018] 2) This utility model uses a flexible pillowcase to partially enclose the support module cluster, covering the top and four sides of the cluster. The adhesive section at the bottom of the flexible pillowcase connects to the bottom of the support module cluster, fixing them in place and preventing relative movement. This allows the support module to maintain a stable posture when no force is applied. When the user's head, shoulders, neck, and spine are pressed against the three-dimensional support pillow, the pressure exerted by the user's body during turning or moving is transmitted through the flexible pillowcase to the support module cluster. Under the influence of force, the upper surfaces of the support blocks slide and rotate on the smooth underside of the pillowcase. While maintaining contact with the flexible pillowcase, the support blocks cause the support rods to rotate. Several support rods and blocks provide support to the head, shoulders, neck, and spine on the flexible pillowcase via torsion springs in various locations.

[0019] 3) This utility model uses heat dissipation channels opened around the bottom of the flexible pillow. The increased gap due to stress deformation and displacement can accelerate the flow of air through the channels, avoiding excessive heat accumulation inside the pillow that could lead to oily head and sweating, thus affecting sleep comfort.

Detailed Implementation

[0031] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0032] Example: Figure 1-8 As shown, the present invention discloses a three-dimensional support pillow, comprising a pillowcase 1 and a flexible pillowcase 2 encased within the pillowcase 1. The flexible pillowcase 2 is composed of a pillow core outer cover 4 encasing a pillow core 3. The pillow core 3 is made of flexible material and is filled within the pillow core outer cover 4. A support module cluster 5 is also installed at the lower end of the pillow core outer cover 4. The top and sides of the support module cluster 5 are embedded within the pillow core outer cover 4, and the lower end of the pillow core outer cover 4 is fixedly connected to the bottom surface of the support module cluster 5. The support module cluster 5 is encased in the top and sides by the flexible pillowcase 2, and the pillow core 3 is filled within the pillow core outer cover 4 to form the flexible pillowcase 2. The flexible pillowcase 2 covers the support module cluster 5, and the bottom of the flexible pillowcase 2 and the support module cluster 5 are detachably connected by an adhesive section for easy cleaning. The pillowcase 1 completely encapsulates the flexible pillowcase 2, the support module cluster 5, and the pillow core outer cover 4.

[0033] Pillow core 3 is primarily made of flexible materials, such as latex, memory foam, and fiber fabrics. Its main functions are: to be sufficiently soft, providing users with ample comfort; to adapt its shape to the contours of the object it supports, creating a highly overlapping profile to conform to the supported object; and when a person lies on the pillow, pillow core 3 deforms under pressure to conform to the body and support module cluster 5, with the support module cluster 5 providing support and pillow core 3 providing flexible cushioning. This enhances comfort and softness by conforming the pillow to the body's contours, eliminating muscle fatigue and improving sleep comfort.

[0034] The support module cluster 5 includes a base module 6, a flexible support block 7 installed at the center of the base module 6, and support mechanisms 8 arranged in groups on both sides of the flexible support block 7. The support mechanisms 8 are staggered on the base module 6 and can be tilted and reset under force. The flexible support block 7 is installed parallel to the base module 6 at the center of the upper end face of the base module 6, dividing the base module 6 into an upper region and a lower region. The support mechanism 8 located in the lower region can tilt downward and automatically reset, and the support mechanism 8 located in the upper region can tilt upward and automatically reset. The central flexible support block 7 is made of flexible material, providing elastic deformation in any direction. The upper and lower support mechanisms 8 are unidirectionally limited. The upper support mechanism 8 can only tilt and deform upwards, and the lower support mechanism 8 can only tilt and deform downwards. When lying on the pillow, taking the lower end of the head in contact with the center point of the pillow as an example, the head first presses the flexible support block 7. When pressing down, the support mechanisms 8 located above and below the flexible support block 7 deform upwards and downwards respectively without interference, while conforming to the contour of the head. When the shoulders continue to press down, the lower support mechanism 8 deforms to conform to the contour of the shoulders for support. When the support mechanism 8 is no longer under force, it resets. Ultimately, the support module cluster 5 will shift with the curvature of the user's head and neck during use, forming a rigid curved surface that is exactly the same as the user's head shape, and providing rigid support for the user's head and neck through the upper flexible pillowcase 2.

[0035] A support ramp 22 is also provided on the side of the base module 6 near the flexible support block 7. The support ramp can further prevent the support rod 11 from tilting to the side near the flexible support block 7. At the same time, the support ramp 22 can add ramps to the support mechanisms 8 on both sides near the flexible support block 7. In this way, when the head squeezes the flexible support block 7, the plane of the base module 6 can avoid direct contact between the head and the head, thus increasing comfort.

[0036] The support mechanism 8 includes a support block 9, a first bearing 10 rotatably connected to the support block 9, a support rod 11 mounted on the first bearing 10, a second bearing 12 mounted on the lower end of the support rod 11, and a limiting connection block 13 rotatably connected to the second bearing 12. The upper end of the support block 9 is flat, and the lower end has bearing seats with shaft holes on both sides. The bearing seats are rotatably connected to the first bearing 10. The flat end also has a spring limiting hole 14 for installing the first torsion spring 18. Both ends of the support rod 11 have U-shaped through holes. Near the two ends, spring limiting holes 15 and 16 are respectively provided. The upper end of the support rod 11 is rotatably connected to the first bearing 10 located below the support block 9, and the lower end is rotatably connected to the second bearing 12. The first torsion spring 18 is sleeved in the middle of the first bearing 10, and its two ends are respectively engaged with the spring limiting hole 14 and the spring limiting hole 15. The limiting connecting block 13 is installed on the base module 6. The side of the limiting connecting block 13 away from the flexible support block 7 is also provided with a rounded corner 20. The flat end of the limiting connecting block 13 has a spring limiting hole 17. The second torsion spring 19 is sleeved in the middle of the second bearing 12, and its two ends are respectively engaged with the spring limiting hole 16 and the spring limiting hole 17.

[0037] The support block 9 rotates freely relative to the support rod 11. The installed first torsion spring 18 initially limits the support block 9 to the upper end of the support rod 11. Whether the support block 9 rotates clockwise or counterclockwise, it will be blocked by the first torsion spring 18. When the support block 9 is rotated under force, the first torsion spring 18 will store force. After releasing the force, the support block 9 will automatically reset. The first torsion spring 18 has a certain angle. Through the spring limiting hole 14 and the spring limiting hole 2 15, it limits the support block 9 when it is not under force, resets it when the force is reduced, and keeps the upper surface of the support block 9 in contact with the surface of the pillow core outer cover 4.

[0038] A reinforcing rib 21 is provided on the side of the support rod 11 near the flexible support block 7. The reinforcing rib 21 extends from the bottom of the support rod 11 to the upper middle part to enhance the structural strength and block the lower end of the support rod 11 to form a one-way limit, so that the support mechanism 8 can only tilt to the side away from the flexible support block 7. The first torsion spring 18 and the second torsion spring 19 play the role of support and reset.

[0039] Similarly, the support rod 11 rotates freely relative to the limiting connecting block 13. The two are initially limited and connected by the installed second torsion spring 19. The bottom of the reinforcing rib 21 is flush with the bottom of the support rod 11, so that it is close to the limiting connecting block 13. When the support rod 11 rotates along the second bearing 12, it will be blocked by the reinforcing rib 21, so that it can only rotate and move in one direction. That is, the upper support mechanism 8 can only rotate upward and the lower support mechanism 8 can only rotate downward. When rotating, the second torsion spring 19 stores force. After releasing the force, the support block 9 resets first and then the support rod 11 resets.

[0040] The pillow cover 4 has adhesive sections 23 extending inward from both sides of its bottom surface. These adhesive sections 23 are detachably connected to the bottom surface of the support module cluster 5. Specifically, the adhesive sections 23 extend inward from both sides of the pillow cover 4, and are detachably bonded by attaching male and female Velcro straps to both the adhesive sections 23 and the bottom surface of the support module cluster 5. The flexible pillowcase 2 partially encloses the support module cluster 5, covering its top surface and four sides. The flexible pillowcase 2 is connected to the bottom of the support module cluster 5 via the adhesive sections 23, fixing them relatively in place and preventing relative movement. This allows the support module to maintain a stable posture when no force is applied. When the user's head, shoulders, neck, and spine are pressed against the three-dimensional support pillow, the pressure exerted by the human body is transmitted to the support module cluster 5 through the flexible pillowcase 2. Under the action of force, the upper surface of the support block 9 slides and rotates on the smooth pillow core cover 4. While the support block 9 is always in contact with the flexible pillowcase 2, it drives the support rod 11 to rotate and shift. Several support rods 11 and support blocks 9 provide support for the head, shoulders, neck, and spine on the flexible pillowcase 2 through torsion springs in various directions, playing a supporting role in three-dimensional space.

[0041] The flexible pillowcase 2 has heat dissipation channels around its bottom, which divide the bottom of the flexible pillowcase 2 into a pair of long side sections and a pair of short side sections. The four sections are not connected to each other and are parallel to the outline of the flexible pillowcase 2. The short side sections are located on the left and right sides, and the long side sections are located on the front and back sides. The corresponding adhesive sections 23 are located on the left and right sides of the pillow core cover 2. After the pillow core cover 4 and the pillow core are assembled, the adhesive sections 23 extend outward from the short side sections and are detachably adhesive to the bottom surface of the support module cluster 5 embedded in the bottom of the flexible pillowcase 2.

[0042] The flexible pillowcase 2 deforms and shifts under stress, which increases the gaps in the heat dissipation channels and accelerates airflow. This prevents excessive heat accumulation inside the pillow, which can lead to oily head and sweating, thus affecting sleep comfort. During long periods of sleep, the heat emitted by the head can be transferred to the outside through the gaps in the support module cluster 5 and the heat dissipation channels on the flexible pillowcase 2, preventing excessive heat accumulation inside the pillow, which can lead to oily head and sweating, thus affecting sleep comfort.

[0043] Both ends of the first torsion spring 18 and the second torsion spring 19 are equipped with protective bends 25 to prevent damage to the support block 9, support rod 11, limiting connecting block 13, or the user. The bends prevent the torsion springs from excessively rubbing against the support block 9, support rod 11, or limiting connecting block 13 during deformation, thus protecting the support mechanism 8, the flexible pillow 2, and the human body. The included angle between the two ends of the first torsion spring 18 and the second torsion spring 19 is 80°, so that the support block 9 and the support rod 11, and the limiting connecting block 13 and the base module 6 maintain a 10° tilt angle when no force is applied, ensuring that the support rod 11 will not be stuck in its original position in a vertical state when it is tilted under force.

[0044] The support mechanisms 8 are evenly distributed in a cross shape on the base module 6, staggered front to back and left to right. The left-right spacing of the support mechanisms 8 is not less than the left-right width of the support block 9, and the front-back spacing is not less than the distance from the second bearing 12 to the top surface of the support block 9. After prolonged use, the support mechanisms 8 can be individually replaced with those of poorer performance to extend their service life. To improve the structural strength of the support rod 9, buckles can be arranged between the limiting connection holes 13 to restrict the lateral freedom of the first bearing 10 and the second bearing 12, preventing displacement during use and connection failure. This effectively restricts the lateral displacement of the connecting bearing between the support rod 9 and the limiting connection block 13, thus improving service life.

[0045] The height of the limiting connecting block 13 is the same as the height of the support block 9, so that when the support rod 11 is subjected to force and pressed against the base module 6, the upper surface of the limiting connecting block 13 and the upper surface of the support block 9 are on the same plane to form support. The distance from the outer side of the reinforcing rib 21 to the center of the second bearing 12 is equal to the distance from the top surface of the limiting connecting block 13 to the center of the second bearing 12, so that when the support rod 11 is subjected to force and pressed against the base module 6, the reinforcing rib and the upper surface of the limiting connecting block 13 are on the same plane to form support. The supporting force of the support mechanism 8 depends on the force of the torsion spring. When a spring with a larger torque is used, the overall force-bearing capacity of the support module cluster 5 is stronger, which is suitable for people with a larger weight. When a spring with a smaller torque is used, the overall force-bearing capacity of the support module cluster 5 is reduced, which is suitable for people with a lighter weight, such as children. When the support mechanism 8 is subjected to a larger force, the support rod 11 will fit against the base module 6, and the top surface of the support block 9, the side of the reinforcing rib 21, and the side of the limiting connecting block 13 will be on the same plane, forming a larger support plane, which will not damage the support mechanism 8 and improve its service life.

[0046] The pillow cover 4 is made of high-strength fiber fabric. When in use, the pillow cover 4 wraps around the pillow core 3, providing it with a protective layer of sufficient strength and toughness to prevent the hard outer surface of the support block 9 in the support module cluster 5 from damaging the pillow core 3 when it slides and rotates; it also provides a smooth outer surface with a low coefficient of friction, allowing the support block 9 in the support module cluster 5 to slide freely on the outer surface of the pillow cover 4.

[0047] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
