Detailed Description

As shown in fig. 1-4, an aluminum alloy section shell comprises a main body frame 1, wherein the main body frame 1 is of an open structure, a cover body 2 is detachably connected to the main body frame 1, the cover body 2 is composed of a plurality of functional cover plates with different functions, the functional cover plates are fixedly connected through connecting pieces, the cover body 2 with an integrated structure with various application functions is formed by assembling the cover body 2 and the main body frame 1, and the whole shell is formed by assembling the cover body 2.

When the electronic product is assembled, components of the electronic product are firstly arranged on the main body frame 1, the functional cover plates are fixedly connected through connecting pieces to form the cover body 2 corresponding to the functional requirements of heat dissipation, sound insulation and the like of the electronic product, and then the cover body 2 is covered on the main body frame 1 to complete the integral assembly of the electronic product. In the embodiment, the main body frame 1 is in an open structure form, so that components and parts are convenient to install, and the problem of inconvenient assembly caused by using cylindrical aluminum alloy sections in the prior art is solved. Meanwhile, the cover body structure in the multi-cover plate assembling mode is flexible in configuration, assembling of aluminum alloy sections in different extrusion directions can be achieved, and the shell with different functions is formed.

As a preferred embodiment, the functional cover plate includes a first functional cover plate 21, a second functional cover plate 22 and a third functional cover plate 23, the connecting piece includes connecting holes 24 respectively and correspondingly formed on the first functional cover plate 21, the second functional cover plate 22 and the third functional cover plate 23, connecting pins 25 are inserted into the connecting holes 24, and the connecting and fixing of the functional cover plates are realized by the pin hole cooperation of the connecting pins 25 and the connecting holes 24.

As shown in fig. 2-3, as a preferred embodiment, the connecting hole 24 is a hinged hole, the connecting pin 25 is a solid pin, and the connection and fixation of each functional cover plate are realized through the interference fit between the hinged hole and the solid pin. In this embodiment, the cooperation precision can be guaranteed through the cooperation of reaming hole and solid round pin, but there is the problem that processing cost is high, simultaneously, interference fit's solid round pin and reaming hole are inconvenient for swiftly assembling.

As another embodiment of the aluminum alloy profile shell, the connecting pin 25 is an elastic pin, and the first functional cover plate 21, the second functional cover plate 22 and the third functional cover plate 23 are connected and fixed by elastic fit of the elastic pin and the connecting hole 24. As shown in fig. 4, the elastic pin is a pin whose outer diameter can be changed according to an external force, and when the elastic pin is installed in the connection hole 24, the elastic pin is compressed to have a smaller outer diameter, and a radial expansion force to the wall of the pin hole is generated, so that the elastic pin cannot be easily separated to ensure that the parts connected by the elastic pin cannot be easily separated. Meanwhile, as the outer diameter of the elastic pin is variable, the requirement on the machining precision of the connecting hole 24 is not high, a reaming hole is not needed, the machining cost can be effectively reduced, and the assembly convenience is greatly improved. In this embodiment, since the outer diameter of the elastic pin varies with the external force, the coaxiality of the two opposite connecting holes 24 connected by the elastic pin cannot be effectively ensured, and the assembly break difference visible to the naked eye easily occurs on the connecting end faces of the cover plates with different functions, so that the appearance quality is affected.

During assembly, the cover body 2 formed by connecting and fixing the first functional cover plate 21, the second functional cover plate 22 and the third functional cover plate 23 is buckled on the main body frame 1, the locking screw penetrates through the correction through hole 11 and is screwed into the limit screw hole 26 in sequence, the preliminary pre-positioning of the cover body 2 is completed without tightening, and then after the gap between the screw and the through hole is utilized to adjust the possible gap, the screw is fastened uniformly, so that the high-precision assembly of the shell is completed.

In this embodiment, under the condition that no additional positioning structure is added, the assembly deviation generated by the connection of the first functional cover plate 21, the second functional cover plate 22 and the third functional cover plate 23 through the connecting pin 25 is corrected, the assembly precision of the housing is improved, and the processing cost of adding the positioning structure is saved.
