[0002] In modern life, the bed pad is an essential furniture in people's bedding. Especially with the increase of people's life pressure, in order to relax in sleep, the elastic bed pad with elastic components is more and more popular. The elastic components of the existing elastic bed pad mostly adopt independent bagged springs, each spring is individually packaged in a spring bag, and then the spring bag is arranged in a pattern, and the arranged spring bag group is covered by a whole piece of foam rubber to form an elastic bed pad.

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.

[0039] Example 1

[0040] Reference Figures 1-11 This embodiment provides an elastic module, including a base plate 1 and elastic units 2 arrayed on the base plate 1; the elastic unit 2 includes a fixed end 21 and a flexible end 22;

[0041] The base plate 1 is provided with a locking structure for limiting and cooperating with the fixed end 21, and the fixed end 21 is provided with a locking engagement structure that forms a detachable engagement with the locking structure.

[0042] In the released state, the elastic unit 2 is positioned on the base plate 1 in a first direction through the limiting engagement of the locking structure and the locking engagement structure, so that the elastic end is located on the side away from the base plate 1; the elastic unit 2 is positioned on the base plate 1 in a second direction, and is fixed in a compressed state through the limiting engagement of the locking structure and the locking engagement structure along the release direction of the elastic unit 2; the first direction and the second direction are opposite.

[0043] The aforementioned elastic module features an elastic unit 2 with a fixed end 21 and a flexible end 22. During normal use, the fixed end 21 connects to the base plate 1, allowing the flexible end 22 to face the user for increased comfort. When the elastic unit 2 is compressed and stored, it is inverted, and the fixed end 21 is then connected to the base plate 1 or the waist ring to fix the elastic unit 2 in a compressed state. This design allows the elastic unit 2 to be compressed and stored while maintaining user comfort during use.

[0044] The above structure is fixed to the base plate 1 by the locking structure of the fixed end 21 when the spring is in the compressed state. Therefore, as long as the fixation between the two is released, the elastic unit 2 can be restored to the released state and the elastic unit 2 can be removed from the base plate 1. Then, the user can rotate the released elastic unit 2 180° and then connect the fixed end 21 and the base plate 1 to complete the installation of the elastic unit 2 in the released state.

[0045] To restore the elastic unit 2 to its released state, this embodiment also includes a release member 3. The release member 3 is used to drive the locking structure to retract radially relative to the locking engagement structure, thereby releasing the limiting engagement between the locking structure and the locking engagement structure. As a simple alternative to this embodiment, the release member 3 can also be used to drive the locking structure to rotate circumferentially relative to the locking engagement structure, thereby releasing the limiting engagement between the locking structure and the locking engagement structure.

[0046] Specifically, the locking structure includes ribs 11 spaced circumferentially. One end of each rib 11 is fixed to the base plate 1, and the other end is a free end. The outer surface of the free end is a first inclined surface 12, and the lower end of the first inclined surface 12 forms a limiting surface 13 with the rib 11 body. Correspondingly, the fixed end 21 is provided with a clearance opening 23 for the locking structure to pass through. The inner diameter of the clearance opening 23 is smaller than the outer diameter of the locking structure in its natural state. This ensures that when the locking structure is not subjected to compression, the limiting surface 13 can engage with the outer surface of the clearance opening 23, i.e., the locking engagement structure. Furthermore, the first inclined surface 12 allows the ribs 11 to contract due to compression as the locking structure passes through the clearance opening 23, enabling it to pass through.

[0047] In order to ensure that the rib 11 is compressed and contracted during the process of the locking structure passing through the relief opening 23, the inner wall of the relief opening 23 forms a second inclined surface 24 that cooperates with the first inclined surface 12. The second inclined surface 24 is in the opposite direction to the first inclined surface 12.

[0048] Similarly, the release element 3 also causes the rib 11 to contract by squeezing the first inclined surface 12, thereby releasing the limiting surface 13 and the outer part of the clearance opening 23, i.e., the locking and fitting structure, from the limiting fit.

[0049] Example 2

[0050] refer to Figures 12-22 The difference between this embodiment and Embodiment 1 is that the base plate 1 in Embodiment 1 is omitted, and a waist ring 4 is used instead. The waist ring 4 is provided with a locking structure for limiting and cooperating with the fixed end 21.

[0051] In this way, elastic units 2 can be installed on both the upper and lower sides of the waist ring 4, thus forming a double-layered elastic module. This differs from the single-layered module in Embodiment 1. Furthermore, different needs can be met by releasing the upper or lower elastic module separately.

[0052] Example 3

[0053] refer to Figures 23-24 This embodiment provides an elastic pad, including the elastic module and soft pad described in Embodiment 2. Of course, the elastic module in Embodiment 1 can also be used.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Any technically equivalent modifications made based on the content of this specification shall fall within the protection scope of the present invention.
