Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of bedding, and particularly relates to a three-dimensional support pillow. Background Art
[0002] At present, the existing pillows on the market are mainly divided into four types: 1. Flexible 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 different material layers or different-shaped blocks stacked together.
[0003] For flexible pillows, the support forces provided by all stressed parts are exactly the same. The support force for the object being carried completely depends on the load magnitude exerted by the object itself on the flexible pillow. However, the human head, shoulder-neck part, and spine are irregular in shape and have non-uniform density. Therefore, when the human head, shoulder-neck part, and spine press on such flexible pillows, the support force received at the lowest end of the head is usually the greatest. This will result in the flexible pillow being unable to provide a more conforming support force for the head, shoulder-neck part, and spine during sleep. For filled pillows, when the fluidity of the filling is too large, when a person's head is placed on the pillow, the internal filling cannot provide relatively effective stable support for the head, shoulder-neck part, and spine, but can only provide a very weak soft support, and the support will change constantly with the change of sleeping posture. When the fluidity of the filling is too small, the internal filling cannot move along with the contour shape of the head, shoulder-neck part, and spine, so it cannot provide a support surface that conforms more to the contour of the head, shoulder-neck part, and spine, resulting in stronger support force in some areas and weaker support force in some areas, which will affect the sleep comfort. For hard pillows, due to their high material hardness, their external shape will not change due to the pressure of the head during sleep, and they can only provide surface support for the relatively flat area of the head or point support for the relatively round part of the head, and their sleep comfort is extremely poor. Composite material pillows have similar problems to flexible pillows. Their external shape is fixed. If a uniform force is applied to the outer surface of each part, its outer surface shape will not change. If we want the composite material pillow and the flexible pillow to provide uniform support force for the head, shoulder-neck part, and spine, then the external contour of the head, shoulder-neck part, and spine needs to be similar or the same as the designed external shape of the pillow. However, there are differences in the body shapes of each person. Therefore, such pillows cannot provide support force that conforms to the contour of the head, shoulder-neck part, and spine for the vast majority of users, resulting in situations such as shoulder-neck soreness, spine fatigue, and muscle soreness that seriously affect sleep quality after a long time of sleep. And during a long sleep process, heat will accumulate inside the flexible pillow, making the temperature in the sleep area relatively high, which affects sleep quality.
[0004] In order to effectively fit the various parts of the user and provide effective support, while also effectively dissipating the heat accumulated in the pillow during sleep, a three-dimensional support pillow is needed to solve the above problems. Summary of the invention
[0005] The purpose of the present invention is to solve the problems existing in the above-mentioned background technology and provide a three-dimensional support pillow. By combining a flexible material layer with a hard support structure, the user can obtain a soft and comfortable skin contact feeling during sleep while the pillow can quickly fit the contour of the head, shoulder, neck and spine, provide three-dimensional support, and eliminate the fatigue damage to the body caused by insufficient support for the head, shoulder, neck and spine during long sleep. The heat dissipation channel set on the flexible pillow can effectively dissipate the heat accumulated in the pillow during sleep, avoid oil and sweating of the head and shoulder due to heat accumulation, and improve sleep comfort.
[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a three-dimensional support pillow, comprising a pillow case and a flexible cover pillow wrapped in the pillow case, wherein a pillow core and a pillow core cover are arranged in the flexible cover pillow, and the pillow core is a flexible material filled in 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 side of the support module cluster are embedded in the pillow core cover, and the lower end of the pillow core cover is fixedly connected to the bottom surface of the support module cluster; The support module cluster includes a base module, a flexible support block located at the center of the base module, and support mechanisms staggeredly installed on both sides of the flexible support block, the support mechanisms are one-way tilting structures and have a reset function, and the support mechanisms located on both sides of the flexible support block move in a direction away from the flexible support block respectively; The support mechanism comprises a support block, a first bearing rotatably connected to the support block, a support rod installed on the first bearing, a second bearing installed at the lower end of the support rod and a limit connecting block rotatably connected to the second bearing, the upper end of the support block is also provided with a spring limit hole 1, the upper and lower ends of the support rod are respectively provided with a spring limit hole 2 and a spring limit hole 3, the lower end of the limit connecting block is also provided with a spring limit hole 4, the first bearing is also sleeved with a first torsion spring, and its two ends are respectively clamped with the spring limit hole 1 and the spring limit hole 2, the second bearing is also sleeved with a second torsion spring, and its two ends are respectively clamped with the spring limit hole 3 and the spring limit hole 4, the side of the limit connecting block away from the flexible support block is provided with a rounded corner, and a reinforcing rib is also provided on the side of the support rod close to the flexible support block, the reinforcing rib extends from the bottom of the support rod to the middle and upper part to enhance the structural strength, and blocks the lower end of the support rod to form a one-way limit, so that the support mechanism can only tilt toward the side away from the flexible support block, and the first torsion spring and the second torsion spring play a supporting and resetting role.
[0007] Furthermore, adhesive sections are connected to extend inwards from the left and right sides of the bottom surface of the pillow core outer cover, and the adhesive sections are detachably connected to the bottom surface of the support module cluster.
[0008] Furthermore, a support inclined surface is also provided on one side of the base module close to the flexible support block.
[0009] Furthermore, protective elbows are installed at both ends of the first torsion spring and the second torsion spring to prevent damage to the support block, support rod, limit connection block or user.
[0010] Furthermore, the support mechanisms are evenly distributed in a cross shape on the base module, arranged in a staggered pattern in the front, back, left, and right directions. Among them, the left-right distance between the support mechanisms is not less than the left-right width of the support block, and the front-back distance is not less than the distance from the second bearing to the top surface of the support block.
[0011] Furthermore, the height of the limit connection block is the same as the height of the support block, so that when the support rod is stressed and fits against the base module, the upper surfaces of the limit connection block and the support block are on the same plane to form a support.
[0012] Furthermore, the distance from the outer side surface of the reinforcing rib to the center of the second bearing is equal to the distance from the top surface of the limit connection block to the center of the second bearing, so that when the support rod is stressed and fits against the base module, the reinforcing rod and the upper surface of the limit connection block are on the same plane to form a support.
[0013] Furthermore, the pillow core outer cover is a high-strength fiber fabric, made of polyester fiber textiles, high-needle-count cotton textiles, etc.
[0014] Furthermore, the inner included angle at both ends of the first torsion spring and the second torsion spring is 80°, so that a 10° inclination angle is maintained between the support block and the support rod, and between the limit connection block and the base module when not stressed, ensuring that the support rod will not be stuck in the original position in a vertical state when stressed and tilted.
[0015] The beneficial effects of the present invention are as follows: 1) By means of the pillow core deforming under force to fit the human body and the support module cluster, the support module cluster provides force support and the pillow core provides flexible buffering, improving comfort and softness when the pillow fits the human body contour, eliminating fatigue damage to the body, quickly and efficiently fitting the contours of different users' heads, shoulders, necks and spines during sleep and lying, providing a three-dimensional support surface and support force, and improving sleep comfort.
[0016] 2) In the present invention, the support module cluster is semi-wrapped by a flexible pillowcase, and the flexible pillowcase wraps the top surface and four side surfaces of the support module cluster. The bonding section at the lower part of the flexible pillowcase is connected to the bottom of the support module cluster, so that the two are relatively fixed and no relative movement will occur. In this way, the support module can maintain a stable posture when not stressed. When the user's head, shoulder and neck, and spine are pressed on the three-dimensional support pillow, when the user turns over or moves, the pressure exerted by the human body acts on the support module cluster through the flexible pillowcase. Under the action of the force, the support blocks on the upper surface slide and rotate under the lower surface of the smooth pillow core outer cover. While always fitting the flexible pillowcase, the support blocks drive the support rods to rotate and displace. A number of support rods and support blocks provide support force for the head, shoulder and neck, and spine on the flexible pillowcase through torsion springs in all directions.
[0017] 3) Through the heat dissipation channels opened around the bottom of the flexible pillowcase in the present invention, the increased gap due to force deformation and displacement can accelerate the air flow therein, avoiding the situation that affects the sleep comfort such as the head getting oily and sweating due to excessive accumulation of heat inside the pillow.

Detailed implementation mode
[0029] The present invention will be further explained and illustrated below in conjunction with the accompanying drawings and specific embodiments.
[0030] Embodiment: As Figure 1-8 shown, a three-dimensional support pillow according to the present invention includes a pillowcase 1 and a flexible pillow 2 wrapped in the pillowcase 1. The flexible pillow 2 is composed of a pillow core outer cover 4 wrapping a pillow core 3. The pillow core 3 is filled with flexible materials in 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 side of the support module cluster 5 are embedded in 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 wrapped by the flexible pillow 2 on the top and side. The pillow core 3 is filled in the pillow core outer cover 4 to form the flexible pillow 2. The flexible pillow 2 wraps the support module cluster 5 and is detachably connected to the bottom of the support module cluster 5 through a bonding section for easy cleaning. The pillowcase 1 wraps the flexible pillow 2, the support module cluster 5 and the pillow core outer cover 4 as a whole.
[0031] The pillow core 3 is mainly made of flexible materials, such as: latex, memory foam, fiber fabric, etc. Its main functions are: soft enough to provide sufficient soft comfort for users; it can change its own shape according to the contour of the object being carried, generating a highly coincident contour to fit the object being carried; when a person lies on the pillow, the pillow core 3 deforms under force to fit the human body and the support module cluster 5. The support module cluster 5 provides force support, and the pillow core 3 provides flexible buffering, improving comfort and softness when the pillow fits the human contour, eliminating fatigue damage to the body, and improving sleep comfort.
[0032] 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 staggeredly installed on the base module 6 and are tilted under force to release force and reset automatically. 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 mechanisms 8 in the lower region can be tilted downward and reset automatically, and the support mechanisms 8 in the upper region can be tilted upward and reset automatically. The flexible support block 7 in the middle is made of a flexible material to provide elastic deformation in any direction. The support mechanisms 8 on the upper and lower sides are unidirectionally limited. The support mechanism 8 in the upper part can only be tilted upward and deformed, and the support mechanism 8 in the lower part can only be tilted downward and deformed. When lying on the pillow, taking the contact between the lower end of the head and the center point of the pillow as an example, the head first presses the flexible support block 7. When continuing to press down, the support mechanisms 8 above and below the flexible support block 7 deform upward and downward respectively without interference, and at the same time conform to the head contour. When the shoulder continues to press down, the support mechanism 8 in the lower part deforms to conform to the shoulder contour for support. When the support mechanism 8 is not stressed, it resets. Eventually, the support module cluster 5 will displace along with the curved surface of the user's head and neck and shoulders during use, forming a rigid curved surface exactly the same as the user's head shape, and providing rigid support for the user's head and neck and shoulders through the upper flexible pillowcase 2.
[0033] On one side of the base module 6 close to the flexible support block 7, a support inclined plane 22 is further provided. Through the support inclined plane, the support rod 11 can be further blocked from tilting towards the side close to the flexible support block 7. At the same time, the support inclined plane 22 can add inclined planes to the support mechanisms 8 on both sides close to the flexible support block 7. In this way, when the head presses the flexible support block 7, direct contact between the plane of the base module 6 and the head can be avoided, increasing comfort.
[0034] The support mechanism 8 includes a support block 9, a first bearing 10 rotatably connected to the support block 9, a support rod 11 installed on the first bearing 10, a second bearing 12 installed at the lower end of the support rod 11, and a limit connection block 13 rotatably connected to the second bearing 12. The upper end of the support block 9 is a plane, and bearing seats with axial holes are provided on both sides of the lower end. It is rotatably connected to the first bearing 10 through the bearing seat, and a spring limiting hole 14 for installing the first torsion spring 18 is also provided on the plane. Both ends of the support rod 11 are U-shaped perforated structures, and a spring limiting hole 2 15 and a spring limiting hole 3 16 are respectively provided near the two ends. 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 the two ends are respectively clamped with the spring limiting hole 14 and the spring limiting hole 2 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 fillet 20, and a spring limiting hole 4 17 is provided on its plane. The second torsion spring 19 is sleeved in the middle of the second bearing 12, and the two ends are respectively clamped with the spring limiting hole 3 16 and the spring limiting hole 4 17.
[0035] The support block 9 rotates freely relative to the support rod 11, and the installed first torsion spring 18 initially limits the support block 9 at 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. The first torsion spring 18 will store force when rotating under force, and will automatically reset the support block 9 after releasing the force. The first torsion spring 18 has a certain angle, and through the spring limiting hole 14 and the spring limiting hole 2 15, the support block 9 plays the role of limiting when no force is applied, resetting when the force is reduced, and ensuring that the upper surface of the support block 9 always fits the surface of the pillow core jacket 4.
[0036] A reinforcing rib 21 is also provided on the side of the support rod 11 close to 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 blocks the lower end of the support rod 11 to form a one-way limit, so that the support mechanism 8 can only tilt toward the side away from the flexible support block 7. The first torsion spring 18 and the second torsion spring 19 play a supporting and resetting role.
[0037] Similarly, the support rod 11 rotates freely relative to the limit connecting block 13, and the two are initially limited and connected by the installed second torsion spring 19, and the bottom of the reinforcing rib 21 is flush with the bottom of the support rod 11, so that it is close to the limit 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 in one direction, that is, the upper support mechanism 8 can only rotate upward, and the lower support mechanism 8 can only rotate downward. The second torsion spring 19 accumulates force during rotation, and after the force is released, the support block 9 is reset first and then the support rod 11 is reset.
[0038] On the left and right sides of the bottom surface of the pillow core outer cover 4, there are adhesive sections 23 extending inwards. The adhesive sections 23 are detachably connected to the bottom surface of the support module cluster 5. Specifically, the adhesive sections 23 extend outwards from the left and right sides of the pillow core outer cover 4. By installing male and female Velcro on the bottom surfaces of the adhesive sections 23 and the support module cluster 5 respectively, detachable adhesion can be achieved. The flexible pillowcase 2 semi-wraps the support module cluster 5, and the flexible pillowcase 2 wraps the top surface and four side surfaces of the support module cluster 5. The flexible pillowcase 2 is connected to the bottom of the support module cluster 5 through the adhesive sections 23, making the two relatively fixed and preventing relative movement. In this way, the support modules can maintain a stable posture when not under force. When the user's head, shoulder and neck, and spine are pressed on the three-dimensional support pillow, the pressure exerted by the human body acts on the support module cluster 5 through the flexible pillowcase 2. Under the action of the force, the support rods 11 and support blocks 9 in different directions slide and rotate on the smooth surface of the pillow core outer cover 4 on the upper surface of the support block 9. While always conforming to the flexible pillowcase 2, the support block 9 drives the support rod 11 to rotate and displace. A number of support rods 11 and support blocks 9 provide support force for the head, shoulder and neck, and spine on the flexible pillowcase 2 in all directions through torsion springs, playing a role in supporting in three-dimensional space.
[0039] There are heat dissipation channels opened around the bottom of the flexible pillowcase 2. The heat dissipation channels divide the bottom of the flexible pillowcase 2 into a pair of long side sections and a pair of short side sections, and the four are not connected to each other and are parallel to the contour of the flexible pillowcase 2. The short side ends 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 outer cover 2. After the pillow core outer cover 4 and the pillow core are assembled, the adhesive sections 23 extend outwards from the short side sections and are detachably bonded to the bottom surface of the support module cluster 5 embedded in the bottom of the flexible pillowcase 2.
[0040] When the flexible pillowcase 2 is deformed and displaced under force, the gap of the heat dissipation channel will increase, which can accelerate the air flow through it, avoiding the situation that affects sleep comfort such as the head getting oily and sweating due to excessive accumulation of heat inside the pillow. During long-term sleep, the heat dissipated by the head can be transferred to the outside through the gaps of the support module cluster 5 and the heat dissipation channels on the flexible pillowcase 2, avoiding the situation that affects sleep comfort such as the head getting oily and sweating due to excessive accumulation of heat inside the pillow.
[0041] Protective elbows 25 are installed at both ends of the first torsion spring 18 and the second torsion spring 19 to prevent damage to the support block 9, the support rod 11, the limit connection block 13 or the user. The setting of the elbows can prevent the torsion springs from being damaged due to excessive friction with the support block 9, the support rod 11 or the limit connection block 13 during the deformation process, and can protect the support mechanism 8, the flexible sleeve pillow 2 and the human body; the inner included angle at both ends of the first torsion spring 18 and the second torsion spring 19 is 80°, so that a 10° inclination angle is maintained between the support block 9 and the support rod 11 and between the limit connection block 13 and the base module 6 when not under force, ensuring that the support rod 11 will not be stuck in the original position in a vertical state when it is tilted under force.
[0042] The support mechanisms 8 are evenly distributed on the base module 6 in a cross shape, arranged in a staggered manner in the front, back, left and right directions. Among them, the left-right distance of the support mechanisms 8 is not less than the left-right width of the support block 9, and the front-back distance is not less than the distance from the second bearing 12 to the top surface of the support block 9. After long-term use, individual support mechanisms 8 with poor performance can be replaced to extend their service life. In order to improve the structural strength of the support rod 9, buckles can be arranged between the limit connection holes 13 to limit the lateral freedom of the first bearing 10 and the second bearing 12, prevent their displacement during use from causing connection failure, effectively limit the lateral displacement of the connecting bearings between the support rod 9 and the limit connection block 13, and improve the service life.
[0043] The height of the limit connection block 13 is the same as the height of the support block 9, so that when the support rod 11 is stressed and fits the base module 6, the upper surfaces of the limit connection block 13 and the support block 9 are on the same plane to form a 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 limit connection block 13 to the center of the second bearing 12, so that when the support rod 11 is stressed and fits the base module 6, the reinforcing rod and the upper surface of the limit connection block 13 are on the same plane to form a support. The magnitude of the supporting force of the support mechanism 8 depends on the force on 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 and is suitable for people with a larger body weight. When a spring with a smaller torque is used, the overall force-bearing capacity of the support module cluster 5 decreases and is suitable for people with a lighter body weight such as children. When the support mechanism 8 is stressed greatly, the support rod 11 will fit the base module 6, and the top surface of the support block 9, the side surface of the reinforcing rib 21 and the side surface of the limit connection block 13 are on the same plane, forming a larger supporting plane, and the support mechanism 8 will not be damaged to improve the service life.
[0044] The pillow core outer cover 4 is a high-strength fiber fabric, made of polyester fiber textiles, high-needle-count cotton textiles, etc. When in use, the pillow core outer cover 4 wraps the pillow core 3, providing it with an outer protective layer with sufficient strength and toughness to prevent the hard outer surface of the support blocks 9 in the support module cluster 5 from damaging the pillow core 3 during sliding and rotation; it can also provide a smooth outer surface with a relatively low coefficient of friction, enabling the support blocks 9 in the support module cluster 5 to freely slide on the outer surface of the pillow core outer cover 4.
[0045] As described above, it is only used to illustrate the technical solution of the present invention rather than to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention shall be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
