Novel anti-vibration integrated distribution box

Abstract

A novel anti-vibration integrated distribution box comprises a cover plate, a box body and a shock absorber. The cover plate and the box body are connected and combined into a relatively closed box body through screws; the matching position of the cover plate and the box body is a boundary, and shock absorbers are installed at the four corners of the bottom of the box body. The box body is an integrated box body made of 7075-T6 aluminum alloy; the shock absorber is mounted in an aircraft equipment compartment for mechanical connection; the front part and the rear part of the box body are provided with socket and binding post assembly mounting holes, the box body is connected with an external power supply to directly supply power to an airplane, and an electrical interface schematic diagram is drawn at the same time. The power distribution box is about 120g in weight compared with a jointed board box body made of materials with the same structure, and the strength of the power distribution box is superior to that of a jointed board type power distribution box; when internal devices are installed, overhauled and replaced, only the cover plate needs to be detached, and compared with assembling and overhauling of a jointed board type box body structure, the assembling and overhauling efficiency is higher, and the appearance is neat and attractive; the power distribution box has the advantages of no excessive splicing parts, good sealing performance, vibration resistance, strong impact resistance, and better strength and stability compared with a common power distribution box.

Description

Technical Field

[0001] The invention relates to a novel anti-vibration integrated power distribution box, belonging to the technical field of power distribution boxes. Background Art

[0002] As a core structural component of aviation control devices, the power distribution box is used for inputting, transmitting and protecting high-power power on board. Existing power distribution boxes are heavy and mostly split structures, resulting in poor sealing of the box, and no anti-vibration device, poor impact resistance, and relatively poor strength and stability. Summary of the invention

[0003] The present invention aims to solve the technical problems that the previous distribution boxes are heavy, mostly split structures, resulting in poor sealing of the box body, no anti-vibration device, poor impact resistance, and relatively poor strength and stability.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: A novel anti-vibration integrated power distribution box comprises a cover plate, a box body and a shock absorber; the cover plate and the box body are connected by screws to form a relatively closed box body; the joint between the cover plate and the box body is a dividing line, and shock absorbers are installed on the four corners of the bottom of the box body; the box body material is an integrated box body made of 7075-T6 aluminum alloy; the shock absorber is installed in the aircraft equipment compartment for mechanical connection; the front and rear parts of the box body are designed with sockets and terminal assembly mounting holes, which are connected to an external power supply to directly power the aircraft, and an electrical interface schematic diagram is also drawn.

[0005] The beneficial effects of adopting the above technical solution are: 1. The present invention optimizes the structure of the distribution box, and replaces the front panel, left panel, right panel and rear panel with an integrated box. The box is made of aluminum alloy (7075-T6), which is about 7% lighter (about 120g lighter) than the panel box made of the same structural material, and the mechanical strength of the integrated box is better than that of the panel distribution box; 2. The distribution box of the present invention uses the joint between the cover plate and the box body as the dividing line. The installation method is that the cover plate and the box body are connected by screws to form a box body. When installing, repairing, and replacing internal components, only the cover plate needs to be removed, and the installation and maintenance are more reliable; 3. The distribution box of the present invention is an integrated box, with a higher installation integration, higher assembly and maintenance efficiency than the panel-type box structure, and a regular and beautiful appearance. Since the integrated distribution box is integrally formed without too many splicing parts, its strength and stability are better than those of ordinary distribution boxes; 4. The front and rear parts of the power distribution box of the present invention are designed with sockets and terminal assembly installation holes according to actual usage conditions, which can be connected to an external power supply to directly power the aircraft. At the same time, a schematic diagram of the electrical interface is drawn to facilitate user installation and use; 5. The integrated power distribution box of the present invention has a high space utilization rate because there is no additional support structure and spacing caused by the splicing structure. At the same time, four shock absorbers are installed around the box body to better resist impact and vibration. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] Figure 1 This is a schematic diagram of the structure of the novel anti-vibration integrated power distribution box of the present invention.

[0007] In the figure: 1-cover plate, 2-box, 3-shock absorber. DETAILED DESCRIPTION

[0008] 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.

[0009] A novel anti-vibration integrated distribution box comprises a cover plate 1, a box body 2 and a shock absorber 3; the cover plate 1 and the box body 2 are connected by screws to form a relatively closed box body; the matching part of the cover plate 1 and the box body 2 is a dividing line, so that when installing, repairing and replacing internal components, it is only necessary to remove the cover plate 1, and the installation and maintenance efficiency is higher; shock absorbers 3 are installed on the four corners of the bottom of the box body 2; the box body 2 is an integrated box body made of 7075-T6 aluminum alloy, and the distribution box body is an integrated type, with a higher installation integration, higher assembly and maintenance efficiency than the panel-type box structure, and a regular and beautiful appearance. Since the integrated distribution box is integrally formed without too many spliced ​​parts, it has good sealing performance. At the same time, it has strong vibration and impact resistance, and its strength and stability are better than those of ordinary distribution boxes. Since the box body 2 is made of 7075-T6 aluminum alloy, its weight is about 7% lighter (about 120g lighter) than a panel box made of the same structural material. The shock absorber 3 is installed in the aircraft equipment compartment for mechanical connection. The front and rear of the box body 2 are designed with sockets and terminal assembly mounting holes to connect an external power supply to directly power the aircraft. At the same time, an electrical interface schematic diagram is drawn to facilitate user installation and use.
