All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. Embodiments of the present application will be described in detail below with reference to the accompanying drawings.

In the description of the present application, it is to be understood that the terms "center", "longitudinal", "lateral", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are used merely for convenience in describing the present application and for simplifying the description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed in a particular orientation, and be operated, and therefore should not be construed as limiting the scope of the present application.

The present application is described in further detail below with reference to fig. 1 to 4.

As shown in fig. 1, the present application provides a rocker arm structure for a door, in an i-beam configuration, comprising:

the restraint end 1 is connected with the actuating cylinder; two connecting holes are formed in the constraint end 1 and used for being connected with the actuating cylinder.

And one end of the loading end 2 is connected with the constraint end 1, and the other end of the loading end 2 is provided with two connecting holes for connecting with the cabin door. The loading end 2 and the restraining end 1 may be integrally formed, and may adopt a stamping process or a 3D printing technology. The adoption of the integral forming reduces the connecting parts and correspondingly reduces the fatigue damage.

An included angle of 5-60 degrees is formed between the constraint end 1 and the loading end 2;

in a preferred embodiment provided by this embodiment, the hatch rocker structure is provided with an opening 3, which reduces the weight of the hatch rocker structure (referred to as this structure). In this embodiment, as shown in fig. 2, three openings 3 are provided, and from left to right, the three openings have lengths of 28mm, 26mm and 31mm, and the three openings have widths of 19.5 mm. The vertical height of the hatch door rocker arm structure is 99mm, the width of the restraint end 1 is 35mm, and the width of the loading end is 31 mm.

As shown in figure 3, the structure adopts an I-shaped beam structure, a thinning area is arranged on a middle support plate, the thickness of the area of the middle support plate is 2mm, and the thinning design is carried out twice, wherein the thicknesses are respectively 1.6mm and 1.4 mm. The i-beam configuration also has an outer frame, as shown in fig. 4, which has a width of 14mm, with a reduced frame width of 9.5 mm.

In the embodiment, the door rocker structure is obtained through topological optimization and finite element analysis, and is compared and verified with the traditional rocker in an experiment mode. The material of the structure is intensively distributed in key areas of the collection, and non-key areas adopt the design of hole opening or thinning, so that the distribution of the material is more reasonable, and the structure has the advantage of high specific strength.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application.
