[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figure 5As shown, this utility model discloses a platform door mounting base, including a horizontal intermediate plate 6, a vertical plate 7, and a folding plate 8; there are two vertical plates 7, symmetrically arranged on both sides of the horizontal intermediate plate 6; the vertical plates 7 are perpendicular to the horizontal intermediate plate 6, and the vertical plates 7 and the horizontal intermediate plate 6 are connected by a first rounded corner 13, the cross section of the first rounded corner 13 being an arc-shaped plate; the vertical plates 7 are connected to the outer folding plate 8 on the opposite side of the first rounded corner 13 through a second rounded corner 14; the folding plate 8 is a horizontal flat plate, symmetrically arranged on both sides of the horizontal intermediate plate 6.

[0024] Two grooves 12 are provided on the outer side of the first rounded corner 13. The grooves 12 are preferably V-shaped grooves. The back of the grooves 12 extends into the inside of the 90° angle between the vertical plate 7 and the horizontal intermediate plate 6 to form the first convex bulge. The grooves 12 are formed by the first rounded corner 13 being recessed into the inside of the 90° angle between the vertical plate 7 and the horizontal intermediate plate 6, that is, concave on the outside and convex on the inside.

[0025] The first convex hull effectively acts as a structural stiffener, enhancing the constraint and control in the vertical direction, thus strengthening the ability to resist structural deformation within the cross-section. From the perspective of structural force distribution, the convex hull can fully bear the outward tension, making the structure more stable.

[0026] The second rounded corner 14 extends into the 90° angle between the vertical plate 7 and the folding plate 8 to form two second convex bulges 10. The back of the second convex bulge 10 is provided with a groove. The second convex bulge 10 is formed by the second rounded corner 14 bulging outward, that is, convex on the outside and concave on the inside.

[0027] The second convex hull 10 effectively serves as a structural reinforcing rib.

[0028] The horizontal intermediate plate 6 has two waist holes 11 extending along the length direction at its center, and the two waist holes 11 are located on the same straight line.

[0029] The folding plate 8 has two slots 9 perpendicular to the length direction. The outer side of the slots 9 has an opening, and the inner side of the slots 9 is semi-circular.

[0030] The existing design of the platform door mounting base requires 10mm of sheet metal to manufacture, while the structure of this utility model only requires 8mm of sheet metal to achieve the original parameters and performance (as shown by simulation comparison).

[0031] This utility model of a platform door mounting base has a more stable structural connection, reduces the thickness of the sheet metal, reduces the amount of sheet metal used, and saves installation space. The structure of this utility model can be processed by die stamping, which has its unique stability and production efficiency, and has a great advantage over bending machine processing.

[0032] The improved structure of this invention can be completed by die stamping. Compared with the manual focusing process of bending machine production, the stamping method is more stable. Bending machine requires four processes to form the product, while the stamping method can form it in one process, which has a great advantage in production efficiency. Furthermore, the die stamping cost is much lower for mass production.

[0033] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
