Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0058] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0059] Referring to Figures 1-21, this embodiment provides a multi-functional mattress frame 5 that can be used in both high and low positions. The mattress frame 5 is composed of several mattress frame units 1 spliced ​​together.

[0060] The mattress frame 5 also includes a first connector 2 and a second connector 3. When several mattress frame units 1 are spliced ​​together in pairs in an array, the first connector 2 and the second connector 3 are used for row and column connections respectively. The first connector 2 splices the mattress frame units 1 along the row direction, and the second connector 3 splices the mattress frame units 1 along the column direction.

[0061] The mattress frame unit 1 includes a base plate 11 and several supporting structures mounted on the base plate 11. The base plate 11 serves as the main body for placing and supporting the mattress 6, and the supporting structures serve as the main supporting components for placing the mattress 6. The splicing of the several mattress frame units 1 is mainly achieved through the splicing of the base plates 11.

[0062] On the four sides of the base plate 11, a first connector 2 and a second connector 3 are respectively arranged on opposite sides. The two sides of the first connector 2 are opposite sides in the row direction, and the two sides of the second connector 3 are opposite sides in the column direction.

[0063] The first connecting member 2 is a snap fastener 23. A snap fastener 21 is provided on one side of a single base plate 11, and a snap fastener 23 is provided on the other side. The snap fastener 21 and the snap fastener 23 constitute the first connecting member 2. Two adjacent mattress frame units 1 are spliced ​​together by the snap fastener 23 on the other base plate 11 and the snap fastener 21 on one of the base plates 11.

[0064] The specific structure of the locking element 21 and the fastener 23 is as follows: two locking elements 21 or two fasteners 23 are provided on each side of the base plate 11 to form a stable snap-fit ​​connection. A locking block 22 is horizontally provided on the locking element 21. The locking block 22 is strip-shaped, with both ends protruding from the main body of the locking element 21. The fastener 23 includes a insertion slot 24 and an elastic release element 25. The insertion slot 24 has an upward-facing insertion port, an outward-facing clearance opening, and an inward-facing space for accommodating the elastic release element 25, allowing the elastic release element 25 to be pressed inwards.

[0065] During assembly, the locking piece 21 is inserted into the fastener 23 from top to bottom, and the locking block 22 is inserted into the insertion slot 24. The main body of the locking piece 21 is locked at the clearance opening, and the insertion slot 24 restricts the movement of the locking block 22 laterally. The elastic release member 25 is provided with a protruding edge 26, which is located on the outer side of the elastic release member 25. The upper end of the protruding edge 26 is provided with a slope. When the locking block 22 is inserted from top to bottom, the locking block 22 squeezes the slope, which acts on the protruding edge 26, causing the elastic release member 25 to deform inward. The protruding edge 26 retracts inward to allow the downward pressing movement of the locking block 22. After the locking block 22 is locked into the insertion slot 24, the protruding edge 26 loses the inward squeezing force and returns to its original position under the elastic action of the elastic release member 25, abutting against the upper end of the locking block 22, thereby restricting the movement of the locking block 22 to be pulled out of the insertion slot 24. During disassembly, simply apply external force to the elastic release member 25, causing the protruding edge 26 to retract inward again to create space, releasing the locking block 22, and then pull it upward.

[0066] The second connector 3 is an independent connector. Pin holes 111 are provided on opposite sides of the base plate 11 to mate with the second connector 3. A resilient pin 31 is provided on the second connector 3 corresponding to each pin hole 111. Four resilient pins 31 are arranged in a matrix on the second connector 3. Two pin holes 111 are provided on each base plate 11 corresponding to each resilient pin 31. One second connector 3 can connect two base plates 11. Two sets of pin holes 111 are provided on one side of the base plate 11, with one set of pin holes 111 corresponding to one second connector 3, forming a stable connection.

[0067] In this embodiment, a mattress frame 5 that can be adjusted to high or low positions is provided, mainly to address the limitations of traditional mattress frames 5 due to their fixed height. Therefore, the support structure provided on the base plate 11 has two sets of structures, namely a first support structure 12 and a second support structure 13. The first support structure 12 is a low-position support structure, and the second support structure 13 is a high-position support structure.

[0068] To facilitate height conversion between high and low positions and subsequent storage and transportation, both the first support structure 12 and the second support structure 13 are designed to be foldable.

[0069] Six support structures are arranged along two rows and three columns on the base plate 11. Each support structure consists of a first support structure 12 and a second support structure 13. Through holes are provided on the base plate 11 corresponding to the support structures. This saves costs and allows for stacking and storage. The structures can be placed on the elastic unit 4 for storage, saving storage space.

[0070] The first support structure 12 is configured as an arc-shaped structure, with two first hinge seats 112 located near the central diameter of the through hole. The two first hinge seats 112 are arranged opposite each other on both sides. The arc-shaped ends of the first support structure 12 are rotatably mounted in the two first hinge seats 112 on both sides, and the first support structure 12 can be flipped up or down relative to the base plate 11 through the hinge connection.

[0071] The base plate 11 has a first slot 113 along the edge of the through hole, and the first support structure 12 has a first protrusion 121 that engages with the first slot 113. A first abutment 114 protrudes inward from the inner edge of the through hole to abut against the arc-shaped structure of the first support structure 12. The first protrusion 121 is perpendicular to the arc-shaped structure of the first support structure 12 and is positioned at the top of the arc-shaped structure. The first slot 113 is positioned to match the position of the first protrusion 121.

[0072] When the first support structure 12 flips upwards by 180°, its curved edge engages with the first abutment 114, preventing further flipping. After flipping 180°, the first protrusion 121 is vertically upwards for assembling the elastic unit 4, at which point the mattress frame 5 transforms into a low mattress frame 5. The first hinge seat 112 protrudes from the base plate 11. The height of the first hinge seat 112 matches the thickness of the first support structure 12, ensuring that after flipping upwards by 180°, the first support structure 12 rests flat on the first abutment 114, preventing instability and tilting when supporting the mattress 6.

[0073] When the first support structure 12 is flipped downwards, it flips 180° back, and the first protrusion 121 is inserted into the first slot 113. The first slot 113 forms a storage for the first protrusion 121, which can protect the first protrusion 121 from bumps and damage, and the first slot 113 provides storage space for the first protrusion 121, which can make the overall storage aesthetically pleasing.

[0074] As shown in Figures 12-18, this embodiment also includes a second support structure 13, which is a folding frame. This support frame is disposed on one side of each row of base plates. The support structure includes a pair of U-shaped frames 131 and a pair of double U-shaped frames 132. The pair of U-shaped frames 131 and the pair of double U-shaped frames 132 are respectively rotatably connected to the top of each row of the two-row, three-column base plates 11. The pair of U-shaped frames 131 are flipped upwards from their bottoms, and one of the U-shaped frames is moved to the other end of the same row of the base plate and abuts against the second slot 115. The pair of U-shaped frames 131 and the base plate 11 form a triangular support structure.

[0075] Specifically, the two ends of a pair of U-shaped frames 131 are rotatably hinged to one side of the base plate 11, which is the side where the first slot 113 is set. Two U-shaped frames 132 are the same size as the U-shaped frames 131. The pair of U-shaped frames 131 and 132 are rotatably hinged at the connecting part, which is opposite to the connecting ends on both sides of the U-shape. A second slot 115 is provided on the side of the base plate 11 opposite to the first slot 113. The second slot 115 protrudes from the lower end of each row of the base plate 11 and has a U-shaped latch structure, with the latch facing the first slot 113. A crossbar 133 is provided at the U-shaped opening of the U-shaped frames 132 and 131, as shown in Figure 13. One of the U-shaped frames 131 and 132 is moved to the bottom of each row of the base plate, and its crossbar 133 is engaged in the second slot 115.

[0076] When the second support structure 13 opens, first flip a pair of U-shaped frames 131 upwards to an angle of approximately 60 degrees, move one of the U-shaped frames to the other end of the base plate in this row, and place its crossbar 133 against the second slot 115 in this row. The three second support structures 13 in this row are opened and erected in the same way. Similarly, open the two U-shaped frames 132 in the second row. After the two U-shaped frames 132 are flipped, move one of the U-shaped frames of the two U-shaped frames 132 to the lower end of the row, and lock the crossbar 133 of the two U-shaped frames 132 into the second slot 115. The second slot 115 restricts the tendency of the two U-shaped frames 132 to open further outwards. At this time, the two U-shaped frames 132 and the base plate 11 form a triangular support structure for high-position support of the mattress 6 structure. At this time, the mattress frame 5 is transformed into a high mattress frame 5. When the second support structure 13 is folded, hold the crossbar 133 and squeeze it inward. The crossbar 133 will disengage from the second slot 115 and fold inward to one side of the U-shaped frame 131, 132. Then flip the U-shaped frame 131, 132 downward and attach it to the base plate 11.

[0077] A second protrusion 134 is provided at the rotational hinge position of the two U-shaped frames 132 and 131. When the pair of U-shaped frames 131 and the pair of two U-shaped frames 132 respectively form a triangular support structure with the base plate 11, the second protrusion 134 is set vertically upward for assembling the elastic unit 4. In this embodiment, the fastener 23 protrudes on the base plate 11, and the fastener 23 is set on the same side as the first slot 113. In order to form a folding mechanism, the second protrusion 134 of the two U-shaped frames 132 is a U-shaped protrusion, and a U-shaped clearance opening 135 is provided on the crossbar 133 of the two U-shaped frames 132. When the second support structure 13 is folded, the U-shaped clearance opening 135 and the U-shaped protrusion can be locked on the side of the fastener 23 to form a perfect storage fit. In order to better fold the second protrusion 134, a placement space 116 is provided in the middle of the base plate 11. The U-shaped structure of the second protrusion 134 can be locked on the side of the corresponding fastener 23 of the adjacent base plate 11 when the base plate 11 is spliced. The reasonable space coordination makes the splicing more convenient.

[0078] The first embodiment is shown in Figure 6-21.

[0079] The first embodiment provides a mattress assembled using a multi-functional mattress frame 5 that can be used for both high and low positions.

[0080] The modular mattress includes several modular mattress frame units 1 and several modular elastic units 4, which can be assembled such that mattress frame units 1 can be assembled with mattress frame units 1, elastic units 4 can be assembled with elastic units 4, and mattress frame units 1 and elastic units 4 can be assembled.

[0081] The elastic unit 4 includes a spring and a cover or flexible support for the built-in spring, wherein the spring is a conical spring. The mattress frame 5 of the mattress is assembled from several mattress frame units 1, and the mattress 6 of the bed is assembled from several elastic units 4, and the mattress 6 also includes a soft padding layer 61 laid on the elastic pad.

[0082] The splicing structure of the mattress frame unit 1 and the elastic unit 4 is as follows: the first support structure 12 and the second support structure 13 of the mattress frame unit 1 are provided with a first protrusion 121 and a second protrusion 134, and the bottom of the conical sleeve of the elastic unit 4 is provided with a groove 41. The groove 41 is inserted into the first protrusion 121 or the second protrusion 134 to form the splicing structure of the elastic unit 4 and the mattress frame unit 1.

[0083] The first embodiment provides a modular mattress with two usable heights. When the first support structure 12 is flipped upwards by 180° and the second support structure 13 is folded up, the first support structure 12 serves as a support connector for the elastic unit 4, and the assembled bed is a low mattress. When the second support structure 13 is folded open a second time and the first support structure 12 is flipped and folded, the second support structure 13 serves as a support connector for the elastic unit 4, and the assembled bed is a high mattress.

[0084] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
