[0039] Here, the technical solutions in the embodiments (or "implementation manners") of the present 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.

[0040] If there are terms related to directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, lateral, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships, motion conditions, etc. between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, terms such as "first" and "second" in the embodiments of the present application are only for the purpose of convenient description and should not be construed as indicating or implying relative importance.

[0041] Next, the embodiments of this specification will be described in detail.

[0042] Referring to Figure 1 As shown, the present application discloses a base structure, which includes a front plate 10, a rear plate 20 and a pair of side plates 30. The front plate 10, the rear plate 20 and the pair of side plates 30 enclose a frame. Among them, 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.

[0043] The base structure further includes a rear beam 40, and the rear beam 40 is assembled between the pair of side plates 30 and is disposed close to the rear plate 20. Among them, the rear beam 40 is made by an extrusion process, and the rear beam 40 can be made of metal or plastic.

[0044] Referring to Figures 2-4 As shown, a plurality of front plate buckle strip receiving grooves 111 are formed on the front plate 10. The plurality of front plate buckle strip receiving grooves 111 are arranged in parallel from top to bottom on the front side of the front plate 10. The openings of the front plate buckle strip receiving grooves 111 face forward. A front plate buckle strip 50 is disposed on one of the front plate buckle strip receiving grooves 111. By tightening the front end face sleeve with the front plate buckle strip 50, the caulking becomes more three-dimensional, ensuring that the shape does not collapse or wrinkle. Among them, the front plate buckle strip 50 is made by an extrusion process, and the material of the front plate buckle strip 50 is metal or plastic.

[0045] A support cavity 114 is further provided at the rear of the front plate buckle strip receiving groove 111. The buckle 113 extends forward from the front wall of the support cavity 114, and the rear wall of the support cavity 114 is flush with the rear wall of the partition cavity 112. In this way, by arranging the support cavity 114 at the rear end of the front plate buckle strip receiving groove 111, the structural strength of the front plate buckle strip receiving groove 111 is enhanced.

[0046] A plurality of partition cavities 112 are further provided on the vertical plate 11. The plurality of partition cavities 112 and the plurality of front plate buckle strip receiving grooves 111 are arranged at intervals in the up and down direction. In this way, the partition cavity 112 not only reduces the overall weight of the front plate 10, saves materials, but also can ensure the strength and stiffness of the front plate 10. In this embodiment, the partition cavity 112 includes end partition cavities 1121 located at the upper and lower ends and two middle partition cavities 1122 provided in the middle.

[0047] A tubular part 115 is provided in the end partition cavity 1122. An installation hole 1151 is formed in the tubular part 115, and the installation hole 1151 is assembled to a pair of side plates 30 by screws. The tubular part 115 extends from the left side to the right side of the vertical plate 11, the installation hole 1151 points to the center of the end cavity 1121, and a long notch 1152 is provided on the tubular part 115.

[0048] Three front plate buckle strip receiving grooves 111 with openings facing forward are provided on the vertical plate 11. One of the front plate buckle strip receiving grooves 111 is provided in the middle of the vertical plate 11, and the other two front plate buckle strip receiving grooves 111 are symmetrically arranged up and down with respect to the front plate buckle strip receiving groove 111 at the middle position. In this way, three different heights of shapes are satisfied, which greatly facilitates production and assembly, and the degree of standardization and integration is higher. The front plate buckle strip 50 is made by an extrusion process, and the material of the front plate buckle strip 50 is metal or plastic.

[0049] Refer to Figure 4 and Figure 7 As shown, a buckle 113 extending outward is provided in the front plate buckle strip receiving groove 111, and a card slot 51 for fixing the buckle 113 is provided on the front plate buckle strip 50. The opening sizes at both ends of the card slot 51 are larger than the opening size in the middle. In this way, the buckle 113 can be directly snapped into the card slot 51 from the front side. Among them, when the front plate buckle strip 50 is snapped into the front plate buckle strip receiving groove 111, the front surface 52 of the front plate buckle strip 50 is flush with the front surface 116 of the vertical plate 11.

[0050] A seat spring buckle strip installation rail 121 is provided on the rear side of the horizontal plate 12, and a seat spring buckle strip 60 is provided on the seat spring buckle strip installation rail 121. A front limiting piece 123 extending backward is provided on the front side of the seat spring buckle strip installation rail 121, and a rear limiting piece 124 extending forward is provided on the rear side. The front limiting piece 123 and the rear limiting piece 124 are clamped in the notch 62 of the seat spring buckle strip 60.

[0051] The above-mentioned front limiting piece 123 and rear limiting piece 124 play a limiting role in the front-rear and vertical directions. In addition, a cavity 125 is provided on the front side of the seat spring buckle strip installation rail 121, and the cavity 125 is connected to a partition cavity 112. In this way, 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 guaranteed.

[0052] Refer to Figure 4 and Figure 6 As shown, a hook 122 is provided on the horizontal plate 12. A convex hull 31 is provided on the inner side of the side plate 30, the hook 122 is hung on the convex hull 31, and the vertical plate 11 and the side plate 30 are fixed by screws. The hook 122 is in an inverted L shape and extends backward from the vertical plate 11 and then bends downward. In this way, the alignment is carried out through the convex hull 31 and the hook 122 before screwing to ensure the reliability of the installation position.

[0053] Referring to Figures 4-6 and Figure 8 As shown, barbs 21 are provided at the bottom of the rear plate 20, barbs 33 are provided at the bottom of the side plate 30, and barbs 117 are provided at the bottom of the vertical plate 11. The base structure further includes a plurality of face sleeve buckle strips 70, and face sleeve buckle strips 70 are respectively fixed on the barbs (21, 33, 117). Specifically, the face sleeve buckle strip 70 includes a connecting portion 71 and a locking portion 72. One end of the locking portion 72 is connected to the connecting portion 71, and the other end is elastically clamped with the barbs (21, 33, 117) with the connecting portion 71.

[0054] The present application also discloses a seat, including the above-mentioned base structure. A plurality of front plate buckle strip receiving grooves 111 are formed on the front plate 10. The plurality of front plate buckle strip receiving grooves 111 are arranged side by side from top to bottom on the front side of the front plate 10, and the openings of the front plate buckle strip receiving grooves 111 face forward. A front plate buckle strip 50 is provided on one of the front plate buckle strip receiving grooves 111. Furthermore, the front plate buckle strip 50 can be installed by selecting front plate buckle strip receiving grooves 111 with different heights to meet the requirements of seats with different shapes, and the compatibility is high.
