[0036] Here, the technical solutions in the embodiments (or "implementation manners") of this application will be clearly and completely described in conjunction with the accompanying drawings. When the following description involves the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0037] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, rear, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), then such terms are only used to explain the relative positional relationships and movement conditions between components in a specific posture (as shown in the accompanying drawings); if this specific posture changes, then the directional indication or positional relationship also changes accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of this application are only for the purpose of convenient description and cannot be understood as indicating or implying relative importance.
[0038] Next, the embodiments of this specification will be described in detail.
[0039] Reference Figure 1 As shown, the present application discloses a base structure, which includes a front plate 10, a rear plate 20, a pair of side plates 30 and a rear beam 40. The front plate 10, the rear plate 20, the side plates 30 and the rear beam 40 are assembled together to form a seat frame. The front plate 10, the rear plate 20 and the pair of side plates 30 are made by injection molding, extrusion molding or blow molding processes. The rear beam 40 is made by an extrusion process and can be made of metal or plastic material.
[0040] Reference Figure 2 As shown, the front plate 10 includes a vertical plate 11 and a horizontal plate 12. At the top of the horizontal plate 12, there is a front seat spring buckle strip mounting rail 121. The opening of the front seat spring buckle strip mounting rail 121 faces upward and is assembled with a seat spring buckle strip 50. In addition, the front seat spring buckle strip mounting rail 121 extends in the left-right direction and has openings on both sides. The seat spring buckle strip 50 is inserted into the front seat spring buckle strip mounting rail 121 in the left-right direction. Thus, it is convenient to replace the seat spring buckle strip 50 later.
[0041] The front seat spring buckle strip mounting rail 121 is arranged at the rear side of the horizontal plate 12, and a partition cavity 122 is provided at the front side of the horizontal plate 12. In addition, a plurality of cavities 111 arranged vertically are provided on the vertical plate 11. Thus, not only the overall weight of the front plate 10 is reduced, but also the strength and stiffness of the front plate 10 can be ensured. At the front side of the front seat spring buckle strip mounting rail 121, there is a front limiting piece 1211 extending backward, and at the rear side, there is a rear limiting piece 1212 extending forward.
[0042] The seat spring buckle strip 50 includes a main body portion 51 and a plurality of snap rings 52 located above the main body portion 51. A cavity 511 is provided inside the main body portion 51, and notches 512 are provided at the front and rear sides of the main body portion 51. The front limiting piece 1211 and the rear limiting piece 1212 are respectively clamped in the notches 512. Thus, the front limiting piece 1211 and the rear limiting piece 1212 play a limiting role in the front-rear and vertical directions.
[0043] Reference Figure 3 As shown, at the top of the rear beam 40, there is a rear seat spring buckle strip mounting rail 41. The opening of the rear seat spring buckle strip mounting rail 41 faces upward and is assembled with a seat spring buckle strip 50. The rear seat spring buckle strip mounting rail 41 extends in the left-right direction and has openings on both sides. The seat spring buckle strip 50 is inserted into the rear seat spring buckle strip mounting rail 41 in the left-right direction. Thus, the assembly is convenient and it is easy to replace.
[0044] The rear beam 40 further includes a lower frame body 42 and an upper frame body 43. The upper frame body 43 and the rear seat spring buckle strip mounting rail 41 are located at the upper part of the lower frame body 42, and the rear seat spring buckle strip mounting rail 41 is arranged at the front side of the upper frame body 43. Among them, at the front side of the rear seat spring buckle strip mounting rail 41, there is a front limiting piece 411 extending backward, and the front limiting piece 411 is clamped in the notch 512. Thus, the front limiting piece 411 plays a limiting role in the front-rear and vertical directions for the seat spring buckle strip 50.
[0045] The top of the upper frame body 43 is provided with an upper cover plate 431. The upper cover plate 431 includes a rear limiting piece 4311 that extends forward above the recoil spring buckle strip mounting rail 41. A plurality of snap rings 52 are clamped below the rear limiting piece 4311. In this way, the recoil spring buckle strip 50 can be further limited in the vertical direction by the rear limiting piece 4311.
[0046] The upper cover plate 431 further includes a buckle strip positioning piece 4312 that protrudes obliquely downward from the upper frame body 43. A face cover buckle strip 60 is arranged on the buckle strip positioning piece 4312. In this way, the leather cover on the recoil spring 70 can be tightened to prevent the leather cover from wrinkling, enabling the user to have a certain sense of resilience when sitting on the seat and ensuring comfort.
[0047] Refer to Figures 4 - 5 As shown, the two recoil spring buckle strips 50 are respectively connected to the recoil spring 70 to form a support structure, and the recoil spring 70 can provide a comfortable sense of resilience for the user. Further, the recoil spring 70 is arranged to slope downward from front to back. In this way, when the user sits on the base structure, they will not slide out, ensuring high safety.
[0048] Refer to Figures 2 - 3 and Figures 6 - 7 As shown, barbs 13, 21, and 31 are provided at the bottoms of the front plate 10, the rear plate 20, and the side plate 30. The base structure further includes a plurality of face cover buckle strips 60, and the face cover buckle strips 60 are respectively fixed on the barbs 13, 21, and 31. In this way, the leather cover outside the seat is tightened from four directions to prevent the leather cover from wrinkling, enabling the user to have a certain sense of resilience when sitting on the sofa and ensuring comfort.
[0049] This application also discloses a seat, including the above-mentioned base structure. By providing a front recoil spring buckle strip mounting rail 121 at the top of the front plate 10 and assembling a recoil spring buckle strip 50, and providing a rear recoil spring buckle strip mounting rail 41 at the top of the rear beam 40 and assembling a recoil spring buckle strip 50, it is convenient to disassemble and replace the recoil spring buckle strip 50 later, which is simple and convenient.
[0050] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the drawings; all modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this application shall be included within the scope of protection of this application.
