Description

Technical Field

[0001] This utility model relates to the field of power distribution boxes, and specifically to a novel power distribution device structure. Background Technology

[0002] With the continuous innovation and development of aviation technology, aviation equipment is gradually being upgraded, and the demand for its power distribution devices is also constantly changing and updating. New power distribution devices have become the primary choice for supporting new aviation equipment. This new power distribution device is a structural component of a new type of aviation equipment power distribution device, used in high-power onboard power supply devices. It is small in size, light in weight, low in economic cost, and has good natural heat dissipation performance.

[0003] The new power distribution unit is a product designed to support a new type of aviation equipment. It is used to install high-power loads and possesses excellent natural heat dissipation performance. Previous power distribution units were mostly of one-piece or modular structures. One-piece structures involved complex machining methods such as milling, resulting in high costs. Modular structures typically used multiple panels connected by screws, with the panels also requiring complex machining methods such as milling, offering slightly lower costs. The new power distribution unit requires a certain level of mechanical strength, simple manufacturing processes, and excellent natural heat dissipation performance to meet the requirements of installing high-power components, maintaining low costs, and achieving good natural heat dissipation. Conventional power distribution unit structures cannot simultaneously meet the requirements of simple manufacturing processes and good natural heat dissipation, making the development of this type of power distribution unit quite challenging.

[0004] To meet the operational requirements of small size, light weight, and good natural heat dissipation performance of new power distribution boxes, and to improve the natural heat dissipation performance and structural mechanical strength of power distribution devices, the development and design of new power distribution devices is imperative. For example, Chinese invention patent CN118768870A discloses a method for processing a power distribution box for amphibious aircraft. The method involves welding two or more reinforcing ribs to the back of a stainless steel plate, drilling two or more heat dissipation holes in another stainless steel plate, welding reinforcing ribs around the perimeter of the stainless steel plate, and then welding mounting ears to the four corners of the stainless steel plate to obtain the base plate. A stainless steel plate is then bent into a U-shape using sheet metal bending. A stainless steel plate of the same size as the front panel is used as the rear panel, and the U-shape and rear panel are welded together using a seamless welding process to form an outer cover. The front panel and base plate are mechanically connected, and support frames are welded to both sides of the front panel and the base plate. Finally, the front panel and base plate, connected in step four, are bolted together to fix the outer cover into a box structure, thus obtaining the power distribution box for a certain type of amphibious aircraft. However, the invented distribution box has the problem of exceeding the weight limit. Summary of the Invention

The bottom plate is planar on one side facing the interior of the enclosed structure, and has reinforcing ribs and heat dissipation teeth on the opposite side. Mounting brackets are also provided at the four corners of the base plate.

[0007] Preferably, the mounting bracket is a trapezoidal frame structure with reinforcing ribs evenly distributed radially from the center to the three sides inside, and mounting holes are respectively opened on the top and bottom surfaces of the mounting bracket.

[0009] Preferably, the side plate has mounting holes for installing high-power wiring assemblies.

[0010] Preferably, the cover plate, side plate and bottom plate are connected and fixed to each other by screws.

[0011] Preferably, the reinforcing ribs are distributed on the base plate at equal intervals according to the mechanical strength and weight of the distribution box.
