Description

Corner braced thin-walled shell construction

technical field

The utility model relates to a thin-walled shell structure, in particular to an angle-supported thin-walled shell structure.

Background technique

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.

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.

Two types of thin-walled shell structures are generally used in the prior art. A thin-walled shell structure is realized by integrated processing, that is, all or part of the shell is processed by casting or monolithic cutting. The disadvantages of this solution are:

The structural size is limited, the cost is high, the production cycle is long, and it is not suitable for high-tech small-batch products such as instruments and meters; the internal components of the product are difficult to install, and it is not easy to connect the components; the filling ratio of the internal cavity of the structure is low, resulting in the overall size of the product. Large and redundant in shape, it is not conducive to participating in market competition.

Another product shell structure is shown in Figure 1, which is composed of multiple panels spliced together, and the adjacent panels are 90° to each other. At each seam, secure the connection with screws from the side. When connected as a whole, the plates support each other and have a certain overall rigidity; at the same time, the sealing strips buried at each joint are compressed to form a sealing effect. This technique has at least the following disadvantages:

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. The appearance of the casing is monotonous and lacks aesthetic feeling.

Utility model content

The purpose of this utility model is to provide a corner with a stable and reliable mechanical structure, which can improve the stability and rigidity of the overall structure of the shell, ensure the structural position relationship between the panels of the shell, reduce the number of screw holes on the outer surface, and have a beautiful appearance. Supports thin-walled shell structures.

The purpose of this utility model is achieved by the following technical solutions:

The angular support thin-walled shell structure of the utility model includes a shell, the shell is mainly composed of a plurality of panels, and the top angles of three adjacent panels are connected by an angular support structure, and the angle support structure has three The mating surfaces of the three panels are matched with the mating surfaces of the three panels respectively and fixed by mechanical connectors.

It can be seen from the above-mentioned technical solution provided by the utility model that the angle-supported thin-walled shell structure provided by the embodiment of the utility model can improve the overall rigidity of the shell due to the stable and reliable mechanical structure of the corner-supported parts, and there is no need to provide The additional shell connection and supporting frame can reliably ensure the relative positional relationship between the shell panels, take into account the structural strength of the shell and the size and weight of the equipment, facilitate the installation of various components in the equipment, improve the space utilization rate inside the equipment, and reduce the screw holes on the outer surface Quantity makes the appearance rich in changes and has a sense of the times.

The preferred embodiment of the angle-supported thin-walled shell structure of the present utility model is:

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.

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

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

The outer contour surface is flush with the panel.

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

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

The three panel mating surfaces of the corner support structure are perpendicular to each other or form an acute angle or an obtuse angle.

As shown in Figures 2a and 2b, in the corner-supported thin-walled shell structure of the present invention, corner-supported parts are provided at the eight corners of the original thin-walled shell structure, which can improve the overall rigidity of the shell and ensure that the plates of the shell are The relative positional relationship between them, reducing the number of screw holes on the outer surface, makes the appearance rich in changes, and has a sense of the times.

Specific embodiment one:

As shown in Figure 3a, Figure 3b, and Figure 3c, the corner support components include: 1 piece of corner support and 3 pieces of bolts.

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.

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 are effectively connected and fixed with each shell panel.

With the application of the utility model, after the corner supporting parts and the shell panels are installed in place, the four corners of each panel have a larger contact area, the anti-overturning moment is greatly improved, and the overall rigidity is enhanced. The four corners of each panel are firmly fixed on the corner support by bolts; and the uniqueness of the assembly position is guaranteed through the cooperation of the cylindrical surface. The three mutually perpendicular installation surfaces of the corner support ensure that the three adjacent panels are 90° to each other. Thereby, the relative positional relationship between the plates of the housing is ensured.

As shown in Figure 4, using the corner support structure, each shell panel can be fully positioned with four bolts. Another screw is reserved in the middle of each side for compressing the sealing strip. Therefore, the number of screw holes on the outer surface is greatly reduced. At the same time, the corner supports play a decorative role on the shell, making the shape of the whole machine rich in changes, with a simple and generous aesthetic feeling of softness and rigidity.

Specific embodiment two:

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