[0004] The present application relates to the technical field of furniture mattresses, and in particular to an elastic mattress with a modular structure. Background Art

[0005] To ensure comfort and softness, mattresses typically have a built-in support structure, typically a spring system, consisting of individual springs arranged in regular rows and columns. The most typical spring structure involves individually enclosing the springs in pockets, securing them within the pockets through ultrasonic welding. The pockets are then welded together to form a series of pocketed springs. Each string of springs is cut to the desired length and assembled in rows. After each row of pocketed springs is aligned and secured with glue, forming a vertically aligned spring structure.

[0006] However, this type of spring structure is welded and glued together to form a single piece. During mattress assembly, the spring structure is custom-made to fit the mattress's dimensions, resulting in limited adaptability and size adjustment. Furthermore, if a single-piece spring structure experiences partial collapse, the entire mattress must be replaced, increasing both its lifespan and overall cost.

[0007] Summary of the Invention

[0036] The present application is further described in detail below with reference to Figures 1-6.

[0037] As shown in Figures 1-2, the embodiment of the present application discloses an elastic mattress with a modular structure, which is provided with a comfort layer 1, a spring structure and a base 3 from top to bottom, and is covered with a bedspread to form a complete mattress.

[0038] In this embodiment, the spring structure is formed by splicing together a plurality of spring modules 2. These modules 2 are all of the same shape and size, and can be rectangular. These modules 2 are assembled on the base in a plug-in manner to form an array arrangement. This plug-in arrangement achieves plug-in engagement by providing a recess on one of the base 3 and the spring module 2, and a protrusion on the other.

[0039] A plurality of recesses 31 are further provided on the base 3 for correspondingly splicing the spring modules 2. The recesses 31 are divided and distributed in an array according to the size of the base 3, and the spring modules 2 are installed in the corresponding recesses 31 to form a support structure of the mattress, as shown in FIG3 .

[0040] In this embodiment, as shown in Figure 4 , a protrusion 21 is provided at the bottom of the spring module 2, with the protrusion 21 being positioned so as to engage with the recess 31. Sponge or silicone is embedded in the protrusion 21, forming the protrusion 21 with a certain hardness and engagement thickness, so that the protrusion 21 can be stably engaged with the corresponding recess 31, thereby preventing the spring module 2 from accidentally sliding out and causing the risk of collapse due to displacement of the spring module 2.

[0041] The recess 31 of the base 3 can be a hollow design or a design with a certain depth but not through the base 3. In order to maintain a certain hardness, the base 3 is preferably made of fabric-coated silicone or hard sponge.

[0042] In this embodiment, the four corners of the comfort layer 1 are magnetic, and the spring module 2 at the corresponding position has a magnetic structure, and the comfort layer 1 is fixed by the magnetic structure. The comfort layer 1 can further improve the softness of the mattress, and the comfort layer 1 provides the mattress with a fluffy feeling, beautifies the mattress, and provides an intuitive soft feeling visually.

[0043] The comfort layer 1 serves as the active surface in direct contact with the human body and is made of a material with elastic deformation, which may include a foam polymer. The elastic characteristics of the comfort layer 1 are different from those of the spring module 2. In other words, the elastic modulus of the comfort layer 1 is smaller than the elastic modulus of the spring module 2. However, as the direct contact surface, the comfort layer 1 is softer and fluffier than the spring module 2.

[0044] Furthermore, in order to quickly identify the spring module 2 as a module with a magnetic structure, a corresponding mark 231 is set on the spring module 2 with a magnetic structure. Preferably, a mark 231 is set on the upper cover 23 of the spring module 2 to correspond to a specified splicing position.

[0045] In this embodiment, the spring module 2 comprises a base box 22 and an upper cover 23, as shown in Figure 5. The base box 22 houses several spring cores 4, which serve as an elastic support structure and are elastically deformable in at least one direction. A zipper opens and closes the base box 22 and upper cover 23, allowing for easy replacement of the spring cores 4. It is worth noting that the spring module 2 itself is also replaceable. If the spring structure partially collapses, either the entire spring module 2 or the spring core 4 can be replaced, depending on usage. This makes the mattress easy to maintain and simple to replace, offering both selectivity and practicality.

[0046] In this embodiment, the upper cover 23 is translucent, and the bottom box 22 is a pure cotton bottom box 22. The translucent upper cover 23 can facilitate clear observation of the use and damage of the bag spring 41, making it convenient for maintenance and replacement.

[0047] Furthermore, as shown in Figure 6, the spring core 4 is composed of a number of cloth-bag springs 41, which are arranged in rows and columns according to the size of the base box 22 to avoid the spring module 2 being too large and the splicing adjustment being unchanged, or the spring module 2 being too small, resulting in too scattered splicing and a large amount of engineering work. The maximum number of combinations of the spring core 4 is 12 cloth-bag springs 41, and the minimum is 6 cloth-bag springs 41.

[0048] The pocket spring 41 includes a pocket 411 and a spring 412 . The spring 412 is placed in the pocket 411 and is welded together by ultrasonic welding to form the pocket spring 41 .

[0049] In the first embodiment, the bag spring 41 can be connected by ultrasonic welding or gluing. The spring core 4 formed by this connection method is an integrated structure. When replacing, the spring module 2 is mainly replaced.

[0050] In the second embodiment, there is no direct connection between the cloth bag springs 41. The cloth bag springs 41 are scattered parts. Compartments are set in the bottom box 22. Each compartment is correspondingly installed with a cloth bag spring 41. When replacing, the cloth bag springs 41 are replaced as the main body.

[0051] Furthermore, the compartment has a height limit, which allows the pocket spring 41 to be partially placed in the compartment, with the portion protruding from the compartment serving as the deformation amount of elastic deformation. The height difference between the compartment and the pocket spring 41 serves as the deformation of the pocket spring 41.

[0052] The compartment and the bottom box 22 are detachably connected, cooperating with the pocket springs 41 at different heights. For example, the compartment can be positioned near the ends of the pocket springs 41, allowing one end of the pocket springs 41 to have a higher elastic deformation than the other, with that end serving as the primary contact and force-bearing end. Alternatively, the compartment can be positioned in the middle of the pocket springs 41, allowing both ends of the pocket springs 41 to have a certain amount of elastic deformation. This structure allows the mattress to be used alternately on both sides.

[0053] A latching structure is provided in the cavity of the bottom box 22 so that the compartment is fixed at different positions of the bag spring. The latching structure includes a buckle structure.

[0054] In the third embodiment, the plug-in method takes the base 3 as an example, in which a recess 31 is provided and the spring module 2 is provided with a protrusion 21. The position setting of the protrusion 21 can be set at different positions on the side of the spring module 2 in the height direction of the spring module 2, so that the spring module 2 is plugged into the corresponding recess 31 with the annular boundary of the protrusion 21 in contact with the corresponding edge surface of the recess 31 and the protrusion 21 rests on the edge surface, so that the spring module 2 is stable in the corresponding recess, avoiding tilting relative to the recess 31 or sliding out of the recess 31.

[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
