Description

Technical Field

[0001] The invention relates to a novel sheet metal panel distribution box, belonging to the technical field of distribution box manufacturing. Background Art

[0002] The new power distribution box is a structural component of an aviation control device, used for inputting, transmitting and protecting high-power power on board. The existing power distribution box has the following problems: 1. The structural assembly of the distribution box is more complicated. The left side panel, right side panel and front panel need to be assembled on the bottom plate. At the same time, the weight is heavier than the panel box composed of the same structural material. Since the left side panel, right side panel and front panel are assembled, the mechanical strength is poor, and the appearance is irregular and unsightly; 2. The upper part of the distribution box uses a whole cover plate, which needs to be opened to inspect the internal parts, thus greatly reducing the safety and maintainability of the product and making it inconvenient for field maintenance of the distribution box; 3. The distribution box is integrated, which is not easy to disassemble, install and repair; 4. The front panel of the power distribution box does not have an electrical interface diagram based on actual usage, which is not convenient for users to install and use; 5. The front panel of the power distribution box is not equipped with a terminal assembly, and cannot be conveniently connected to the aircraft electrically. The front panel is not designed with a high-power power socket installation hole, so the aircraft cannot be directly powered by an external power supply connected through the power socket, which reduces the practicality of the power distribution box. Summary of the invention

[0003] The present invention aims to solve the technical problems that the box is heavy, has poor mechanical strength, and has an irregular and unsightly appearance; has poor safety and maintainability, and is inconvenient for field maintenance of the distribution box; is not easy to disassemble, install and repair; is not convenient for users to install and use; and the distribution box has poor practicality.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: A new sheet metal panel distribution box, comprising a rear panel, a cover plate C, a cover plate A, a cover plate B, a sheet metal integrated front panel and a bottom plate; a sheet metal integrated front panel is fixed on the top of the bottom plate by screws, a cover plate A and a cover plate B are fixed on the top of the sheet metal integrated front panel by screws, and the mating point between the cover plate A and the cover plate B is the dividing line of the distribution box; a rear panel is fixed to the rear of the sheet metal integrated front panel by screws, and a cover plate C is fixed on the rear panel by screws.

[0005] The sheet metal integrated front panel is made of 5A05-O aluminum alloy with a thickness of 1.5 mm.

[0006] The sheet metal integrated front panel is equipped with a terminal assembly, a high-power power socket mounting hole, and a device mounting hole.

[0007] The beneficial effects of adopting the above technical solution are: 1. The present invention optimizes the structure of the distribution box, optimizes the design of each component, and integrates the left side panel, the right side panel, and the front panel into a front panel using sheet metal parts. The weight is about 9% lighter (about 80g) than the panel box composed of the same structural material. The mechanical strength of the sheet metal integrated front panel is also better than that of the panel, and the appearance is regular and beautiful. 2. The distribution box of the present invention uses the seam between cover A and cover B as the dividing line, and cover B can be opened to inspect the internal parts. This greatly improves the safety and maintainability of the product and facilitates the field maintenance of the distribution box; 3. The distribution box of the present invention is a modular box, and the cover plate assembly, cover plate B, rear panel, bottom plate and sheet metal integrated front panel are assembled into a box structure by screws. The cover plate assembly, cover plate B and rear panel assembly can be disassembled, installed and repaired by a screwdriver; 4. The front panel of the power distribution box of the present invention is provided with an electrical interface schematic diagram according to the actual usage, which is convenient for users to install and use; 5. The sheet metal integrated front panel of the power distribution box of the present invention is installed with a terminal assembly to be electrically connected to the aircraft. The sheet metal integrated front panel is designed with a high-power power socket installation hole. The installed power socket can be connected to an external power source to directly supply power to the aircraft, thereby increasing the practicality of the power distribution box. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 This is a schematic diagram of the structure of the new sheet metal panel distribution box of the present invention.

[0009] In the figure: 1-rear panel, 2-cover C, 3-cover A, 4-cover B, 5-sheet metal integrated front panel, 6-bottom plate. DETAILED DESCRIPTION

[0010] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0011] A new type of sheet metal panel distribution box, such as Figure 1As shown: it includes a rear panel 1, a cover plate C2, a cover plate A3, a cover plate B4, a sheet metal integrated front panel 5, and a bottom plate 6; the sheet metal integrated front panel 5 is fixed on the top of the bottom plate 6 by screws. Since the front panel, the left panel, and the right panel are replaced by the sheet metal integrated front panel 5, the mechanical strength of the sheet metal integrated front panel 5 is better than that of the panel-type distribution box. The cover plate A3 and the cover plate B4 are fixed on the top of the sheet metal integrated front panel 5 by screws. The matching place of the cover plate A3 and the cover plate B4 is the dividing line of the distribution box. The cover plate B4, the cover plate C2, and the rear panel 1 can be opened to inspect and replace the internal devices and parts, which greatly improves the safety and maintainability of the product and facilitates the field maintenance of the distribution box; the rear panel 1 is fixed on the rear of the sheet metal integrated front panel 5 by screws, and the cover plate C2 is fixed on the rear panel 1 by screws. The present invention is a modular type, with a higher installation integration, a shorter assembly time than the panel-type box structure, and a regular and beautiful appearance. Its installation method is to connect the box body by screws, which is simple and reliable for installation and maintenance; The sheet metal integrated front panel 5 is made of 5A05-O aluminum alloy, has a thickness of 1.5 mm, and is about 9% lighter (about 80 g lighter) than a panel box made of the same structural material.

[0012] The sheet metal integrated front panel 5 is installed with a terminal assembly and a high-power power socket installation hole and a device installation hole. The terminal assembly installed on the sheet metal integrated front panel 5 is electrically connected to the aircraft, and the high-power power socket installation hole and the device installation hole provided on the sheet metal integrated front panel 5. The installation socket can be connected to an external power supply to directly power the aircraft, and the internal device can provide protection for the electrical equipment, thereby increasing the compatibility and integration of the distribution box.

[0013] The structure of the new sheet metal panel distribution box is a combination of sheet metal parts and panels. This structure can not only meet the mechanical strength requirements, but also meet the weight limit requirements. The new distribution box is used as a supporting product for a certain type of aircraft, for internal load power supply and protection, and realizes aircraft power distribution integration and compatibility functions.

[0014] The present invention is mainly mechanically connected to the aircraft equipment compartment through the mounting ears provided on the bottom plate 6 .
