Problems solved by technology

[0007] The structure is unstable, and the mating surfaces between adjacent panels are small. When the shell receives a large impact force in a certain direction, the small mating surface cannot provide sufficient anti-overturning moment, resulting in some shell panels The shell structure is deformed by tilting after being stressed; in the structural design, it is necessary to provide an additional structural frame to connect or support the shell; due to the error in the machining dimensions of each panel, it is difficult to ensure that the adjacent panels are 90 to each other after splicing °; There are many screw holes on the outer surface, and it is difficult to design various changes in the shape
Make the appearance of the shell monotonous and lack aesthetic feeling

specific Embodiment approach

[0021] The angle support thin-wall shell structure of the present invention, its preferred embodiment is:

[0022] It includes a shell, the shell is mainly composed of a plurality of panels, the top corners of three adjacent panels are connected by a corner support structure, and the corner support structure has three panel mating surfaces, and the three panels are respectively connected with After the mating surfaces of the three panels are mated, they are fixed by mechanical connectors.

[0023] The panel mating surface is the outer contour surface or the inner contour surface of the corner support structure.

[0024] The panel and the matching surface of the panel are positioned by pins and fastened by threads.

[0025] The outer contour surface is flush with the panel.

[0026] The panel and the panel mating surface are positioned and screwed together by the mating surface.

[0027] The outer contour surface is provided with a step structure matched with the panel.

specific Embodiment 1

[0030] Such as Figure 3a , Figure 3b , Figure 3c As shown, the corner support components include: 1 corner support and 3 bolts.

[0031] Corner Support - The exterior has three mutually perpendicular mounting surfaces for the installation of three adjacent panels. The contact area of ​​the installation surface is relatively large, and the mutual vertical precision between the panels can be effectively guaranteed. The three edges of the corner support protrude from each installation plane, and its outline matches with the shell panel, which can effectively locate the position of each panel. The three edges and sharp corners can be designed with rounded corners, chamfered corners and bevels of various sizes according to the shape of the whole machine.

[0032] Bolts - Install after housing panels are installed. The screw thread is connected with the corner support, and the round platform is centered with the round hole of the panel, so that the corner support components ...

specific Embodiment 2

[0035] Such as Figure 5 As shown, the angular support structure is designed as an obtuse angle. In practical applications, the angular support structure can be designed in the form of multiple angles as required, thereby forming shells of various shapes.

Abstract

The invention discloses a corner supporting thin-wall shell structure which comprises a shell structure body. The shell structure body is formed by connecting a plurality of panels. Connecting corners of every three adjacent panels are connected through a corner supporting component, the corner supporting components comprise corner supports, each corner support comprises three intersection faces, each intersection face is provided with a connecting hole position, and every three panels are fixedly connected with the corresponding three intersection faces through bolts. Through the corner supporting structure, the overall rigidity of the thin-wall shell structure can be improved, the relative position relation between the panels of a shell can be guaranteed, the number of screw holes in the outer surface can be reduced, the appearance is made to be changeable, and the period feel is achieved.

Description

technical field [0001] The invention relates to a thin-walled shell structure, in particular to an angle-supported thin-walled shell structure. Background technique [0002] Thin-walled shells are currently widely used in various instrumentation products. The thin-walled shell can provide installation space for the internal parts of the product; form an overall protection for the product; provide an installation reference for the interior and exterior of the equipment; conduct internal heat to the outside world; at the same time, it will not increase the weight of the product too much. Thin-wall housings are an important part of instrumentation products. [0003] For airborne and vehicle-mounted instruments, the operating environment is relatively harsh (vibration, dust, temperature changes, etc.), and there are strict requirements on the quality of the whole machine. Therefore, the instrument shell adopts a thin-walled shell, which requires good rigidity and sealing. [...
