Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and more specifically, to an elastic structure and an elastic pad. Background Technology

[0002] Currently, elastic pads are widely used. Comfortable elastic pads can eliminate fatigue. In traditional elastic pads, the spring assembly, filling layer, and fabric layer are tightly connected. Alternatively, all the springs used inside the elastic pad are connected in series or molded as a single piece. Therefore, when a target object is placed on a traditional elastic pad, the pad will sink down and compress all the springs, or the springs will interfere with each other, making it impossible for the elastic pad to provide personalized support for different target objects. Consequently, it cannot adapt to the weight of different target objects, making it difficult to fit different weights, resulting in poor wrapping comfort.

[0003] In summary, the existing elastic pads have the following problems: they cannot provide personalized support for the target object, have poor adaptability, low fit, and poor wrapping feel. Utility Model Content

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0039] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0040] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0041] As disclosed in the background section, existing elastic pads mostly employ a mesh-distributed spring structure, combined with an elastic pad filling layer to form the pad surface. Therefore, in traditional elastic pads, the spring assembly, filling layer, and fabric layer are tightly connected, or all the springs inside the pad are connected in series or molded as a single piece. Consequently, when a user lies on a traditional elastic pad, the pad will sink down and compress all the springs, or the springs will interfere with each other, making it impossible for the elastic pad to provide personalized support for different users. Therefore, it cannot adapt to different users' weights, making it difficult to conform to different user body weights and providing a comfortable, enveloping feel. Furthermore, most elastic pads use a fixed structure, making them difficult to clean and maintain, and resulting in a limited lifespan.

[0042] In addition, existing elastic pads are usually soft contact surfaces, which cannot specifically massage key areas such as the back, so the comfort level is difficult to meet the needs of users with high health requirements.

[0043] In view of this, the present invention provides a novel elastic structure and elastic pad. It should be noted that, unless otherwise specified, the features in the embodiments of the present invention can be combined with each other.

[0044] See Figures 1 to 4This utility model embodiment provides an elastic structure 100 for splicing to form a complete elastic pad, which can bring personalized support effects to different users, so that the elastic pad can conform to the body curves of different users, improve the user's sleep comfort, and is easy to clean and maintain.

[0045] The elastic structure 100 provided in this embodiment of the present invention includes a load-bearing layer 110 and a first support layer 130. The load-bearing layer 110 has a lattice-like structure and is configured to bear the weight of the target object. The first support layer 130 has a lattice-like structure and is distributed with a plurality of interlaced first support ribs 133. The first support layer 130 is disposed on one side of the load-bearing layer 110, and a first support surface 139 is formed on the side of the first support layer 130 away from the load-bearing layer 110. The first support surface 139 is configured to contact the target object and conform to the surface curve of the target object. The hardness of the first support layer 130 is less than that of the load-bearing layer 110.

[0046] It should be noted that the elastic pad in this embodiment can be a mattress, seat cushion, or backrest cushion, etc. The elastic pad in this embodiment can improve comfort and experience, for example, when a user is watching or playing e-sports. This application scenario is just an example and is not limited to this scenario. As for other scenarios, it can be used in home scenarios, office scenarios, or even on ships.

[0047] This embodiment uses an elastic mattress as an example. In this embodiment, both the load-bearing layer 110 and the first support layer 130 are prepared using 3D printing technology, and they can be printed in one step. The different hardnesses of the first support layer 130 and the load-bearing layer 110 are achieved by changing the material ratio and crystal structure during printing. Using 3D printing, the hardness can be configured based on the actual user's weight, or different hardnesses can be set according to different weight ranges, thus achieving personalized customization. Furthermore, the structure formed by 3D printing is easy to clean. Of course, in other preferred embodiments of this invention, other processes can also be used to prepare the load-bearing layer 110 and the first support layer 130. The target object can include, but is not limited to, at least one of the human body and animals.

[0048] Furthermore, this embodiment of the invention employs a single-unit structure, that is, multiple elastic structures 100 are spliced ​​together to form an elastic pad. During splicing, the bearing layer and the first support layer 130 are aligned with each other. This splicing method minimizes the mutual influence between the elastic structures 100, providing personalized support for different users. Moreover, the first support layer 130 has lower hardness, and the first support surface 139 conforms to the body curves of different users, improving sleep comfort. The spliced ​​single-unit structure is also easy to assemble and disassemble, making cleaning and maintenance convenient. Of course, in other preferred embodiments of this invention, the multiple elastic structures 100 can also be integrally molded to form a partial or overall elastic pad structure.

[0049] It is worth noting that in this embodiment, the hardness of the first support layer 130 is less than that of the load-bearing layer 110. Specifically, the hardness of the first support layer 130 and the load-bearing layer 110 can be determined based on the sparseness of the crystal lattice structure and the thickness of the ribs in the crystal lattice structure. Generally, the sparser the crystal lattice structure, the lower the hardness; similarly, the finer the ribs in the crystal lattice structure, the lower the hardness. Specific structural relationships can be found in subsequent explanations.

[0050] Furthermore, the first support layer 130 includes multiple first support units 131, each containing multiple interlaced first support ribs 133. These first support units 131 are spaced apart and evenly distributed on the surface of the load-bearing layer 110, with the surfaces of the multiple first support units 131 furthest from the load-bearing layer 110 flush with each other, and are joined to form a first support surface 139. Specifically, the load-bearing layer 110 is a monolithic structure, and the multiple first support units 131 are spaced apart and joined to form the first support layer 130. This allows the first support surface 139 to be divided into multiple units within a single elastic structure 100, resulting in a more refined and personalized support structure. Moreover, the spaced-apart first support units 131 allow each unit to be independently configured, unaffected by adjacent or other support units, thus providing a more personalized support effect for the target object. This also results in a higher degree of conformity to the object's curves, better matching different objects and providing a better sense of enclosure for the user.

[0051] In some embodiments, each first support unit 131 is rectangular in shape, and multiple first support units 131 are arranged in an array on the load-bearing layer 110. Specifically, the outer contour of each first support unit 131 is rectangular in shape and arranged in an array, so that the first support surface 139 formed by splicing them together is also rectangular, which better splices together to form a complete elastic pad. Of course, in other preferred embodiments of the present invention, multiple first support units 131 can also be distributed in a honeycomb pattern, with each first support unit 131 being hexagonal prism, which can also be well spliced ​​together to form a complete elastic pad. The specific shape of the first support unit 131 is not specifically limited here.

[0052] In some embodiments, each first support unit 131 includes multiple overlapping first hollow lattice layers 135, each first hollow lattice layer 135 including multiple first lattice structures 137 connected in a mesh, and each first lattice structure 137 having multiple intersecting first support ribs 133. Specifically, each first support unit 131 adopts a 3D printed layered structure, and the multiple first hollow lattice layers 135 can be interconnected to form an overall lattice structure. Each first hollow structure includes multiple repeating units, and each repeating unit forms a first lattice structure 137. Here, the first lattice structure 137 being connected in a mesh means that multiple repeating units are interconnected in a mesh pattern and evenly distributed in the same plane. Each repeating unit is composed of multiple intersecting first support ribs 133. In both the horizontal and vertical directions, the first support unit 131 is formed by multiple repeating and ordered repeating units. This structure can ensure the overall structural strength on the one hand, and the uniformity of force on the other hand.

[0053] In some embodiments, a plurality of first massage heads 170 are provided on the side of the first support layer 130 away from the load-bearing layer 110. Further, at least a portion of the first support units 131 are provided with a plurality of first massage heads 170 on the side away from the load-bearing layer 110. Each first massage head 170 protrudes relative to the first support surface 139 in a direction away from the load-bearing layer 110 and is configured to contact the target object and perform a massage function. Specifically, the first massage head 170 protrudes 2-10mm relative to the first support surface 139, enabling point-like massage of the target object surface when the first support surface 139 is in contact with it. Preferably, each surface of the first support unit 131 is provided with a plurality of first massage heads 170, thereby achieving a full-body massage. Of course, in other preferred embodiments of this invention, the first massage heads 170 can also be selectively provided, for example, the first support unit 131 in areas requiring focused massage, such as the spine, shoulders, and waist of the target object, can be provided with first massage heads 170.

[0054] It should be noted that when splicing to form the elastic pad, multiple elastic structures 100 can be spliced to form different regions. The first massage heads 170 can be provided in different regions as required. Moreover, the sizes and heights of the first massage heads 170 in different regions can also be different, so as to achieve targeted massage effects in different regions.

[0055] Furthermore, multiple first massage heads 170 are correspondingly arranged at the intersections of multiple first support ribs 133. Specifically, multiple first massage heads 170 respectively correspond to multiple first lattice structures 137 that form the first support surface 139, and each first massage head 170 is arranged at the intersection of multiple first support ribs 133 in the corresponding first lattice structure 137. At the same time, multiple first massage heads 170 can be evenly distributed in an array. This setting method, on the one hand, can provide centralized support. The intersections of multiple ribs in the first lattice structure 137 are usually the strongest parts of the whole structure, so they can provide the greatest support force. Setting the first massage heads 170 here can ensure their stability during use and prevent them from shifting or deforming due to pressure. On the other hand, this setting method can evenly disperse the pressure. The structure at the intersection can better disperse the pressure from the first massage heads 170, avoiding excessive load on a local part of the elastic pad, thereby prolonging the service life of the elastic pad. In addition, setting the first massage heads 170 at the intersections of the first support ribs 133 can make the first massage heads 170 better conform to the body curve and improve the massage effect, especially in areas such as the spine, shoulders, and waist that require key massage, and better massage effects can be achieved.

[0056] In some embodiments, the bearing layer 110 includes an outer lattice structure 111 and an inner lattice structure 113. The outer lattice structure 111 covers the outer side of the inner lattice structure 113. The outer lattice structure 111 has first bearing ribs 115 distributed in a mesh pattern, and multiple mutually intersecting second bearing ribs 117 are arranged inside the inner lattice structure 113. Specifically, the outer lattice structure 111 is relatively flat and can wrap the inner lattice structure 113 to make the whole bearing layer 110 flat. The inner lattice structure 113 is in a "rice" shape, which can achieve bearing and has a stable structure.

[0057] Furthermore, the distribution density of the first bearing ribs 115 is less than the distribution density of the second bearing ribs 117. Specifically, the outer lattice structure 111 is relatively sparse and flat, while the inner lattice structure 113 is relatively dense, which can improve the bearing effect and structural stability. It should be noted that the distribution densities of the first bearing ribs 115 and the second bearing ribs 117 here refer to the number of the first bearing ribs 115 and the second bearing ribs per unit volume.

[0058] It is worth noting that the distribution density of the second load-bearing rib 117 is greater than that of the first support rib 133, thereby ensuring greater rigidity and better load-bearing capacity of the load-bearing layer 110. Simultaneously, the diameter of the second load-bearing rib 117 is greater than that of the first support rib 133, meaning the second load-bearing rib 117 is thicker, further ensuring greater rigidity of the load-bearing layer 110. Of course, in other preferred embodiments of this invention, the first support rib 133 and the second load-bearing rib 117 may have the same distribution density, but the second load-bearing rib 117 may be thicker; or the first support rib 133 and the second load-bearing rib 117 may have the same thickness, but the second load-bearing rib 117 may have a higher distribution density.

[0059] See Figure 5 In some embodiments, the elastic structure 100 further includes a second support layer 150. The second support layer 150 has a lattice-like structure and is disposed on the side of the load-bearing layer 110 away from the first support layer 130. A second support surface is formed on the side of the second support layer 150 away from the load-bearing layer 110. The second support surface is configured to contact and conform to the curve of the target object. The hardness of the second support layer 150 is less than that of the load-bearing layer 110. Specifically, the first support layer 130 and the second support layer 150 are respectively disposed on both sides of the load-bearing layer 110, and the hardness of the second support layer 150 is also less than that of the load-bearing layer 110, so that the second support layer 150 can also support the target object through the second support surface.

[0060] Furthermore, the hardness of the second support layer 150 is different from that of the first support layer 130. Preferably, the hardness of the second support layer 150 is greater than that of the first support layer 130. By forming a first support layer 130 and a second support layer 150 with different hardnesses on both sides of the load-bearing layer 110, the user is given another option. The user can switch the elastic structure 100 according to their needs, and can use either the first support surface 139 or the second support surface to approach the target object to experience different levels of softness and hardness.

[0061] In some embodiments, the thickness of the second support layer 150 is less than or equal to the thickness of the first support layer 130. Specifically, since the second support layer 150 has a relatively higher rigidity, it requires less cushioning space, and therefore its thickness can be smaller, thereby saving materials and reducing manufacturing costs.

[0062] In some embodiments, the second support layer 150 includes a plurality of second support units 151, each of which has a plurality of interlaced second support ribs 153. The plurality of second support units 151 are spaced apart and evenly distributed on the surface of the load-bearing layer 110 away from the first support layer 130, and the surfaces of the plurality of second support units 151 away from the load-bearing layer 110 are flush with each other and spliced ​​together to form a second support surface. Specifically, the plurality of second support units 151 are spaced apart and spliced ​​together to form the second support layer 150, so that within a single elastic structure 100, the second support surface can also be divided into multiple units, thereby making the support structure more refined and more personalized. Furthermore, the plurality of second support units 151 are spaced apart, and each second support unit 151 can be set independently, and the force is not affected by adjacent or other support units, thereby further providing a personalized support effect for the target object, and the fit to the curve of the target object is higher, making it more suitable for different target objects, and giving the user a better sense of enclosure.

[0063] In other preferred embodiments of the present invention, there is no gap between adjacent second support units 151, thereby forming a continuous second support layer 150.

[0064] It should be noted that the second support unit 151 and the first support unit 131 have the same projected area on the horizontal plane. Multiple second support units 151 and multiple first support units 131 are respectively arranged opposite each other on both sides of the load-bearing layer 110, so that the partitioning effect of the first support surface 139 and the second support surface is the same. Of course, in other preferred embodiments of this invention, the projected areas of the second support unit 151 and the first support unit 131 on the horizontal plane can also be different, thereby achieving different levels of partitioning fineness and bringing different experiences.

[0065] In some embodiments, each second support unit 151 is rectangular in shape, and multiple second support units 151 are arranged in an array on the load-bearing layer 110. Specifically, the outer contour of each second support unit 151 is rectangular in shape and arranged in an array, so that the second support surface formed by splicing them together is also rectangular, which better splices together to form a complete elastic pad. Of course, in other preferred embodiments of the present invention, multiple second support units 151 can also be distributed in a honeycomb pattern, with each second support unit 151 being hexagonal prism, which can also be well spliced ​​together to form a complete elastic pad. The specific shape of the second support unit 151 is not specifically limited here.

[0066] In some embodiments, each second support unit 151 includes multiple overlapping layers of second hollow lattice layers. Each layer of the second hollow lattice layer includes multiple second lattice structures connected in a mesh pattern. Each second lattice structure contains multiple intersecting second support ribs 153. Specifically, each second support unit 151 adopts a 3D-printed layered structure, and the multiple layers of the second hollow lattice layers can be interconnected to form an overall lattice structure. Each layer of the second hollow structure includes multiple repeating units, and each repeating unit forms a second lattice structure. Here, the mesh connection of the second lattice structure refers to the multiple repeating units being interconnected in a mesh pattern and evenly distributed in the same plane. Each repeating unit is composed of multiple intersecting second support ribs 153. In both the horizontal and vertical directions, the second support unit 151 is formed by multiple repeating and ordered repeating units. This structure can ensure the overall structural strength on the one hand, and the uniformity of force on the other hand.

[0067] It should be noted that the layered structure of the second support unit 151 is similar to that of the first support unit 131, and the first support unit 131 can be referred to for details.

[0068] In some embodiments, at least a portion of the second support units 151 are provided with a plurality of second massage heads 190 on the side away from the load-bearing layer 110. Each second massage head 190 protrudes relative to the second support surface in a direction away from the load-bearing layer 110 and is configured to contact the target object and perform a massage function. The second massage head 190 protrudes 2-10mm relative to the second support surface, enabling point-like massage of the target object surface when in contact with the second support surface. Preferably, each surface of the second support unit 151 is provided with a plurality of second massage heads 190, thereby achieving a full-body massage. Of course, in other preferred embodiments of this invention, the second massage heads 190 can also be selectively provided, for example, second massage heads 190 can be provided on the second support units 151 corresponding to areas of the target object that require focused massage, such as the spine, shoulders, and waist.

[0069] In some embodiments, a plurality of second massage heads 190 are correspondingly disposed at the intersections of a plurality of second support ribs 153. Specifically, the plurality of second massage heads 190 are applied to a plurality of second lattice structures constituting the second support surface, and each second massage head 190 is disposed at the intersection of a plurality of second support ribs 153 in the corresponding second lattice structure. Simultaneously, the plurality of second massage heads 190 can be evenly distributed in an array. This arrangement provides concentrated support, as the intersections of multiple ribs in the second lattice structure are typically the strongest parts of the entire structure, thus providing maximum support force. Distributing the second massage heads 190 at these intersections ensures stability during use, preventing displacement or deformation due to pressure. Furthermore, this arrangement evenly distributes pressure; the structure at the intersections better disperses the pressure from the second massage heads 190, avoiding excessive localized load on the elastic pad, thereby extending the lifespan of the elastic pad. In addition, placing the second massage head 190 at the intersection of the second support ribs 153 allows the second massage head 190 to better conform to the body curves and improve the massage effect, especially in areas that require focused massage, such as the spine, shoulders, and waist, where a better massage effect can be achieved.

[0070] In some embodiments, the distribution density of the second load-bearing rib 117 is greater than the distribution density of the second support rib 153, and the distribution density of the second support rib 153 is greater than the distribution density of the first support rib 133. Specifically, the distribution density of the support ribs makes the hardness of the load-bearing layer 110 greater than the hardness of the second support layer 150, while the hardness of the second support layer 150 is greater than the hardness of the first support layer 130.

[0071] In some embodiments, the diameter of the second load-bearing rib 117 is larger than the diameter of the second support rib 153, and the diameter of the second support rib 153 is larger than the diameter of the first support rib 133. Specifically, by adjusting the thickness of the support ribs, the hardness of the load-bearing layer 110 can be greater than the hardness of the second support layer 150, while the hardness of the second support layer 150 can be greater than the hardness of the first support layer 130.

[0072] It is worth noting that in this embodiment, the distribution density of the second load-bearing rib 117 is greater than that of the second support rib 153, and the distribution density of the second support rib 153 is greater than that of the first support rib 133. This ensures that the load-bearing layer 110 has the maximum hardness and a better load-bearing effect, and achieves different support effects for the first support layer 130 and the second support layer 150. Simultaneously, the diameter of the second load-bearing rib 117 is greater than that of the second support rib 153, and the diameter of the second support rib 153 is greater than that of the first support rib 133. That is, the second load-bearing rib 117 is the thickest, the second support rib 153 is the second thickest, and the first support rib 133 is the thinnest. This further ensures that the load-bearing layer 110 has greater hardness and achieves different support effects for the first support layer 130 and the second support layer 150.

[0073] See Figure 6 This utility model embodiment also provides an elastic pad 200, including a plurality of the aforementioned elastic structures 100 spliced ​​together. Each elastic structure 100 includes a load-bearing layer 110 and a first support layer 130. The load-bearing layer 110 has a lattice structure and is configured to bear the weight of the target object. The first support layer 130 has a lattice structure and is disposed on one side of the load-bearing layer 110. A first support surface 139 is formed on the side of the first support layer 130 away from the load-bearing layer 110. The first support surface 139 is configured to contact the target object and conform to the curve of the target object. The hardness of the first support layer 130 is less than the hardness of the load-bearing layer 110.

[0074] In this embodiment, the elastic pad 200 can be composed of multiple elastic structures 100 to form multiple partitions, each partition including at least one elastic structure 100. This arrangement facilitates handling and cleaning. The elastic structures 100 within the same partition can have the same hardness, while the elastic structures 100 in different partitions can have different or the same hardness.

[0075] It should be noted that the multiple elastic structures 100 can be spliced ​​together to form elastic pad partitions, or multiple elastic structures 100 can be integrally formed using 3D printing technology. The specific setting method is not limited.

[0076] The elastic structure 100 and elastic pad 200 provided in this embodiment of the invention have a first support layer 130 on one side of the load-bearing layer 110. The load-bearing layer 110 is prepared by 3D printing technology and has a lattice structure, capable of bearing the weight of the target object. The first support layer 130 is also prepared by 3D printing technology and has a lattice structure. The hardness of the first support layer 130 is lower than that of the load-bearing layer 110. Furthermore, the first support layer 130 can form a first support surface 139 on the side away from the load-bearing layer 110. This first support surface 139 can contact and conform to the curve of the target object. Compared to the prior art, this embodiment of the invention uses a single-unit structure, which is spliced ​​together to form the elastic pad, resulting in less mutual influence and providing personalized support for different users. The lower hardness of the first support layer 130, combined with the first support surface 139 conforming to the body curves of different users, improves sleep comfort. The spliced ​​single-unit structure is also easy to disassemble and assemble, making cleaning and maintenance easier.

[0077] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
