Specific embodiments

[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0040] In the embodiment, Figure 1 and 4 give, an automobile seat cushion spring frame assembly, optionally but not limited to including: a load-bearing main body 1;

[0041] A return spring 2, arranged inside the load-bearing main body 1;

[0042] A bottom plate 3, arranged on the load-bearing main body 1, for limiting the return spring 2;

[0043] Two connection assemblies 4 symmetrically arranged inside the load-bearing main body 1, including a connection sleeve 41 arranged inside the load-bearing main body 1; a limit rod 42 slidably arranged inside the connection sleeve 41, for limiting the bottom plate 3;

[0044] A pressing plate assembly 5, slidably arranged on the load-bearing main body 1.

[0045] In this embodiment, an automobile seat cushion spring frame assembly of the present utility model is given. By arranging the bottom plate 3 on the load-bearing main body 1, and limiting the bottom plate 3 through the connection assembly 4, and through the connection assembly 4, the bottom plate 3 can be quickly detached from the load-bearing main body 1, so that the return spring 2 inside the load-bearing main body 1 can be replaced, thereby avoiding the need to replace the entire seat cushion spring frame assembly, thereby reducing the use cost of the seat cushion spring frame assembly. When the seat cushion is vibrated, the return spring 2 will buffer the pressing plate assembly 5, thereby ensuring the comfort of the automobile seat cushion spring frame assembly during use.

[0046] Further, as Figure 1 shown, the bearing body 1 in the preferred embodiment of the present utility model includes an installation groove 11 opened on the lower end surface of the bearing body 1; two installation holes 12 symmetrically opened on the outer side of the bearing body 1, and the installation holes 12 communicate with the installation groove 11 for connecting the installation of the component 4; a plurality of placement holes 13 evenly distributed and opened on the upper end surface of the bearing body 1, and the placement holes 13 communicate with the installation groove 11; four sliding grooves 14 symmetrically opened in pairs in the bearing body 1 for installing the pressing plate assembly 5.

[0047] More specifically, a connecting sleeve 41 is arranged inside the installation hole 12.

[0048] More specifically, a plurality of reset springs 2 are respectively arranged in a plurality of placement holes 13.

[0049] In this embodiment, multiple preferred embodiments of the bearing body 1 are given. By placing the bottom plate 3 in the installation groove 11, the bottom plate 3 is limited, and through the connecting component 4 in the installation hole 12, the bottom plate 3 is limited. At the same time, the reset spring 2 is placed in the placement hole 13 to ensure the stability of the reset spring 2 during use. Then, through the sliding groove 14, the pressing plate assembly 5 slides in the sliding groove 14, so that when the pressing plate assembly 5 slides, it cooperates with the reset spring 2 to buffer the car seat cushion.

[0050] Further, as Figure 3 shown, the bottom plate 3 in the preferred embodiment of the present utility model further includes a connecting groove 31 opened on the upper end surface of the bottom plate 3 for limiting the reset spring 2; two limiting grooves 32 symmetrically arranged on the outer side of the bottom plate 3, and the limiting rod 42 is located in the limiting groove 32.

[0051] Preferably, the number of the connecting grooves 31 is several, and the connecting grooves 31 are correspondingly opened on the upper end surface of the bottom plate 3 opposite to the placement holes 13.

[0052] In this embodiment, multiple preferred embodiments of the bottom plate 3 are given. Through the connecting groove 31, the lower end surface of the reset spring 2 contacts the inner side of the connecting groove 31, so as to ensure the stability of the reset spring 2 when buffering the car seat cushion. At the same time, by the limiting rod 42 of the connecting component 4 being located in the limiting groove 32, the bottom plate 3 can be limited.

[0053] Further, as Figure 4 shown, the connecting component 4 in the preferred embodiment of the present utility model further includes a blocking plate 43 arranged on the outer side of the limiting rod 42, and the blocking plate 43 is located in the connecting sleeve 41; a compression spring 44 arranged on the outer side of the limiting rod 42, and both ends of the compression spring 44 respectively contact the blocking plate 43 and the inner side of the connecting sleeve 41.

[0054] More specifically, both ends of the limiting rod 42 penetrate through the connecting sleeve 41.

[0055] In this embodiment, multiple preferred embodiments of the connecting assembly 4 are given. By pulling the limiting rod 42, the limiting rod 42 will drive the blocking plate 43 to move, and the moving blocking plate 43 will squeeze the compression spring 44. After the bottom plate 3 is placed in the installation groove 11, release the limiting rod 42. Under the action of the compression spring 44, the limiting rod 42 will automatically enter the limiting groove 32 opened on the bottom plate 3, thereby limiting the bottom plate 3. Conversely, the above operation can detach the bottom plate 3 from the bearing body 1, so as to replace the return spring 2 inside the bearing body 1, thereby reducing the use cost of the automobile seat cushion spring frame assembly.

[0056] Further, as Figure 5 shown, the pressing plate assembly 5 in the preferred embodiment of the present utility model includes four connecting rods 51, which are respectively slidably arranged in four sliding grooves 14; a pressing plate 52, which is arranged between the upper end faces of the four connecting rods 51; a mounting rod 53, which is arranged on the lower end face of the pressing plate 52, and the mounting rod 53 is located inside the return spring 2; and a pressing plate 54, which is arranged outside the mounting rod 53, and the outer side of the pressing plate 54 is in close contact with the inner side of the placing hole 13.

[0057] Preferably, the number of the mounting rods 53 is several, which are arranged on the lower end face of the pressing plate 52 corresponding to the placing holes 13, and the number of the pressing plates 54 is several, which are respectively arranged outside the several mounting rods 53.

[0058] Even further, as Figure 2 and 5 shown, the upper end face of the bearing body 1 is provided with four sliding holes, and the sliding holes are communicated with the sliding grooves 14; the four connecting rods 51 are respectively located in the four sliding holes; and four limiting plates are respectively arranged on the lower end faces of the four connecting rods 51 for limiting the connecting rods 51.

[0059] In this embodiment, multiple preferred embodiments of the pressing plate assembly 5 are given. Through the pressing plate 52, when the pressing plate 52 is squeezed, the pressing plate 52 will drive the pressing plate 54 outside the mounting rod 53 to move downward, so that the pressing plate 54 squeezes the return spring 2, causing the deformation of the return spring 2, buffering the pressing plate 52, and through the connecting rod 51 located in the sliding groove 14, limiting the pressing plate 52 to prevent the pressing plate 52 from falling off the bearing body 1 when the return spring 2 buffers the pressing plate 52.
