[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 4 A composite spring mattress includes a shell 1, an installation groove 2 is provided inside one side of the shell 1, an inspection cover 3 is installed on one side of the shell 1 by bolts to cover the installation groove 2, and a sliding opening 11 is provided on the side of the shell 1 near the positioning element.

[0029] Specifically, the mounting groove 2 is provided with an adjustment mechanism 4 for adjusting the spring inside the housing 1 and a connecting structure, and the outside of the housing 1 is provided with a locking structure for locking the connecting structure. In this embodiment, the adjustment mechanism 4 includes a mounting base 401 fixed to the bottom wall of the mounting groove 2, a connecting base 404 disposed above the mounting base 401, an electric push rod 402 fixed to the mounting base 401, and a slide block 403 slidably disposed on the mounting base 401. A scissor-type support arm 405 is provided between the mounting base 401, the slide block 403, and the connecting base 404. To achieve an elastic connection, the connecting structure includes a crossbar 5 slidably disposed inside the mounting groove 2 and a connecting frame 7 fixed to one side of the crossbar 5 and extending into the housing 1. The top side of the connecting base 404 is fixed to the lower surface of the crossbar 5.

[0030] Both the mounting base 401 and the connecting base 404 have internal sliding grooves 408. The top ends of the scissor-type support arm 405 are each bearing a second roller 407, and the right end of the scissor-type support arm 405 is bearing a first roller 406. The first roller 406 and the two top second rollers 407 are all in rolling connection with the inner side of the sliding groove 408. The housing 1 has a lifting groove 6 communicating with the mounting groove 2, and the connecting frame 7 extends into the housing 1 through the lifting groove 6. Driven by the electric push rod 402, the sliding position of the slide 403 on the mounting base 401 can be precisely controlled. This sliding motion is converted into vertical movement of the connecting base 404 by the scissor-type support arm 405, which in turn drives the crossbar 5 and the connecting frame 7 to move up and down. This design allows the mattress firmness to be adjusted according to the user's personal preferences, providing great flexibility and personalized choice.

[0031] In addition, the design of the scissor-type support arm 405 not only provides the necessary mechanical support, but also ensures stability during the adjustment process through its unique structure. The rolling connection between the first roller 406 and the second roller 407 and the slide 408 reduces friction, making the adjustment process smoother and increasing the durability of the structure.

[0032] It should be noted that the bottom sides of the springs inside the housing 1 are all fixed to the connecting frame 7, which consists of a connecting block and a plate.

[0033] To achieve lifting and locking, the locking structure specifically includes a locking element 8 and a positioning element. One end of the crossbar 5 extends through the sliding opening 11 to the outside of the housing 1. The locking element 8 is installed at the end of the crossbar 5, and the positioning element is installed on the outside of the housing 1. In this embodiment, the locking element 8 includes two mounting blocks 801, a return spring 802 fixed between the two mounting blocks 801, and a locking block 803 that rotates outside one of the mounting blocks 801. The other mounting block 801 is fixed to the end of the crossbar 5.

[0034] A locking rod 804, connected to a positioning element, is fixed to the edge of the locking block 803 away from the mounting block 801. The positioning element includes a locking frame 9 fixed to the side wall of the housing 1. The locking frame 9 has several equidistantly distributed locking holes 91 inside, and the locking rod 804 is inserted into the locking holes 91. The locking element 8 achieves a stable lock on the crossbar 5 through the insertion of the locking rod 804 into the locking frame 9 and its locking holes 91. This design ensures that the mattress remains stable after being adjusted to the desired firmness, preventing accidental movement or deformation.

[0035] The working principle of the above embodiments is as follows:

[0036] First, the mattress is in normal use, the electric push rod 402 is not activated, the slide 403 is located at a certain position on the mounting base 401, the scissor-type support arm 405 maintains a certain angle, the connecting frame 7 is connected to the connecting base 404 through the crossbar 5, the bottom side of the spring is fixed on the connecting frame 7, and the locking block 803, under the action of the return spring 802, the locking rod 804 is inserted into a locking hole 91 of the locking frame 9 to keep the mattress stable;

[0037] When it is necessary to adjust the spring stiffness, the contact locking part 8 is connected, and the user starts the electric push rod 402 through external operation. The electric push rod 402 pushes or pulls the slide 403 to slide on the mounting base 401. The movement of the slide 403 causes the scissor support arm 405 to deform, which in turn causes the connecting base 404 to move up and down. The up and down movement of the connecting base 404 is transmitted to the connecting frame 7 through the crossbar 5, changing the degree of spring compression, thereby adjusting the firmness of the mattress.

[0038] During adjustment, the crossbar 5 moves together with the connecting seat 404, but the locking part 8 always remains outside the housing 1. When it is necessary to lock the mattress firmness, the user releases the pressure of the locking block 803 and rotates the locking block 803 so that the locking rod 804 is inserted into the locking hole 91, thereby realizing the locking function.

[0039] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.

[0040] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
