[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model.

[0035] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0036] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0037] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] As mentioned in the background technology, the door panels of photovoltaic and wind turbine boxes are not strong enough and have large deformation, which may cause problems such as difficulty in opening and closing the door panels or insufficient protection level after closing. Generally, the strength of the door panels is increased by welding reinforcement ribs. However, the setting of reinforcement ribs increases the production process of the door panels, prolongs the production cycle, material costs and manufacturing costs.

[0039] In order to improve the above-mentioned problems, the present application proposes a door panel and a photovoltaic box-type transformer, which increase the strength by arranging rolled ribs on the door panel, thereby eliminating the need to weld reinforcing ribs, reducing the welding process, improving production efficiency, reducing production costs, and enhancing the three-dimensional appearance.

[0040] Figure 1 This is a schematic diagram of the structure of the door panel 10 provided in the embodiment of the utility model. Figure 2Another structural schematic diagram of the door panel 10 provided in the embodiment of the utility model is shown in FIG. Figure 3 Another structural diagram of the door panel 10 provided by the embodiment of the utility model is shown in FIG. Figures 1 to 3 The present application provides a door panel 10, which includes a body 500 and an outer roller bead 100 and an inner roller bead 300 disposed on the surface of the body 500, wherein the inner roller bead 300 is disposed inside the outer roller bead 100, and the inner roller bead 300 and the outer roller bead 100 are surrounded together to form a recess.

[0041] Based on the above configuration, the present application strengthens the door panel 10 body 500 by providing rolling ribs instead of reinforcing ribs, thereby avoiding cumbersome welding procedures and configuring a dedicated welding platform, thereby improving production efficiency and reducing production costs. At the same time, the present application also increases the three-dimensional appearance of the door panel 10, making it more beautiful.

[0042] In some embodiments, the outer roller rib 100 and the inner roller rib 300 are both made by stamping. It should be noted that the specific method is to use a stamping device to stamp the outer roller rib 100 and the inner roller rib 300 on the body 500 according to a preset programming path. After the stamping is completed, the outer roller rib 100 and the inner roller rib 300 both present a strip structure protruding toward the outer wall of the body 500. It can be understood that the strip structure has the same characteristics as the reinforcing ribs in enhancing the strength of the door panel 10, but does not have to have the material cost similar to the reinforcing ribs.

[0043] Furthermore, in order to facilitate the processing and forming of the rolling ribs, the main body 500 is made of a steel plate. It should be noted that the steel plate has excellent performance, has tensile, compressive, bending and shear strength characteristics, can withstand large plastic deformation, and is easy to process.

[0044] Please refer again Figure 1 In order to strengthen the door panel 10 body 500 in multiple directions, the outer roller 100 includes two first rollers 110 spaced apart along a first direction 710, and two second rollers 130 spaced apart along a second direction 730, and the two first rollers 110 and the two second rollers 130 are surrounded together to form a quadrilateral structure, and the first direction 710 and the second direction 730 are perpendicular to each other. Figure 1 As indicated by the arrow.

[0045] Furthermore, if Figure 4 As shown, Figure 4 for Figure 3Schematic enlarged view of the structure at position A in the [Chinese description]. The first rolling rib 110 is parallel to the wall surface of the main body 500 arranged along the second direction 730, the second rolling rib 130 is parallel to the wall surface of the main body 500 arranged along the first direction 710, and the connection part between the first rolling rib 110 and the second rolling rib 130 is arc-shaped.

[0046] Based on the above settings, it can be understood that any one of the first rolling ribs 110 extends along the second direction 730 and is parallel to the wall surface of the main body 500 arranged along the second direction 730; any one of the second rolling ribs 130 extends along the third direction and is parallel to the wall surface of the main body 500 arranged along the first direction 710. That is to say, the distance between the first rolling rib 110 or the second rolling rib 130 and the wall surface of the main body 500 on its adjacent side is fixed.

[0047] It can also be understood that the two first rolling ribs 110 and the two second rolling ribs 130 jointly form a rectangular structure, and the four corners where the first rolling rib 110 and the second rolling rib 130 are connected are arc-shaped to smoothly transition the stress and avoid local stress concentration, causing cracking of the main body 500. And, this arc-shaped structure can be the arc of the inner circle of the above rectangular structure.

[0048] As an optional embodiment, the inner rolling rib 300 straddles between the two first rolling ribs 110, and the inner rolling rib 300 is arranged along the first direction 710. It can be understood that through the above settings, the inner rolling rib 300 is arranged in parallel with the second rolling rib 130 to further strengthen the strength of the main body 500 in the first direction 710.

[0049] Furthermore, the first rolling rib 110, the second rolling rib 130, and the inner rolling rib 300 jointly enclose a rectangular recess. That is to say, the first rolling rib 110, the second rolling rib 130, and the inner rolling rib 300 jointly enclose a "day" - shaped structure, which are connected and strengthened with each other and have hierarchical concave - convex settings, thereby realizing an increase in the overall strength of the main body 500.

[0050] Similarly, as described above, to avoid stress concentration resulting in cracking of the main body 500, the connection part between the inner rolling rib 300 and the first rolling rib 110 is arc-shaped. It can be understood that this arc-shaped structure can be the arc of the inner circle of the rectangular recess.

[0051] In some embodiments, to further enhance the strength and aesthetics of the door panel 10, the number of the inner rolling ribs 300 is at least two, and at least two inner rolling ribs 300 are arranged at intervals along the second direction 730. Specifically, the number of the inner rolling ribs 300 is determined by the size of the door panel 10, and this embodiment does not make a limitation.

[0052] In summary, the present application provides a door panel 10, which includes a body 500 and an outer roller rib 100 and an inner roller rib 300 arranged on the surface of the body 500, wherein the inner roller rib 300 is arranged inside the outer roller rib 100, and the inner roller rib 300 and the outer roller rib 100 are surrounded together to form a concave portion. Based on the above configuration, the present application strengthens the body 500 of the door panel 10 by arranging roller ribs instead of reinforcing ribs, thereby avoiding cumbersome welding procedures and configuring a dedicated welding platform, thereby improving production efficiency and reducing production costs. At the same time, the present application also increases the three-dimensional appearance of the door panel 10, making it more beautiful.

[0053] In addition, the present application also provides a photovoltaic box-type transformer, which includes the door panel 10 in the above embodiment, thereby avoiding cumbersome welding procedures and the configuration of a dedicated welding platform, thereby improving production efficiency, reducing production costs, increasing the three-dimensional appearance, and making it more beautiful.

For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
