Description

Assembled computer host

Technical Field

The invention relates to computer equipment, in particular to an assembled computer host.

Background

The computer is commonly called computer, and is a modern electronic computer for high-speed calculation, which can perform numerical calculation, logic calculation and memory function. The intelligent electronic device can be operated according to a program, and can automatically process mass data at a high speed. In addition to special computers that are widely used in the defense, scientific research, or industrial fields, another widespread use of computers is personal computers. A personal computer refers to a general-purpose computer of a size, price and performance suitable for personal use. Desktop, notebook, to small notebook and tablet computers and ultrabooks, etc. all belong to the personal computers. Although notebook computers and even tablet computers are extremely popular, the desktop computers are the mainstream of personal computers. Desktop computers do, however, have relatively greater performance, and with proper configuration optimization, the performance of a desktop computer will far exceed that of an equivalent laptop or tablet. However, this does not represent a competition or a replacement between desktop, notebook or tablet computers in a personal computer. Desktop computers representing higher performance are increasingly favored by more feverish people in recent years in terms of assemblability and expandability. However, for personal computers that are assembled by individuals, the bottleneck is mainly determined when the computer case is purchased, which is a hidden danger in subsequent upgrading and expanding. Taking a video card as an example, the currently recognized video cards of players are divided into sizes roughly divided into standard cards (about 28 cm), short cards (about 10-20 cm), knife cards (the length is close to that of the short cards, and the height is half of that of the standard cards) and thin cards (the length is close to that of the standard cards, but the thickness is reduced by half). That is, if the player wants to reserve the possibility of upgrading the future display card, the player has to fully consider the overall expandability, such as the size of the chassis, the rated power and installation size of the power supply, the installation size of the motherboard, and the like, when purchasing the assembled computer components. However, in fact, for the current assembled computer, the subsequent upgrade for the motherboard, CPU or graphics card is usually accompanied by the whole replacement of most of the accessories including the chassis, the power supply, the heat dissipation fan, etc., which is not economical, and brings great trouble to the host of the assembled computer. In addition, the case of the current assembled computer which meets the size installation of the standard display card is usually large in size, and the design of the internal air duct is unreasonable, so that even under the condition of ensuring the volume of a small host, the heat dissipation is often not ideal.

As can be seen from FIG. 1, the side panel unit 14 in the present invention is not much different from the side panel of the conventional computer case. In contrast, in the present invention, the main body frame 11 is formed by splicing a plurality of frame components, and as shown in fig. 4 and 5, in the present invention, a plurality of fixing holes for matching with rubber nails (not labeled in the figures) are uniformly distributed on the first frame component 111, the second frame component 112, and the third frame component 113. Specifically, the fixing holes include first fixing holes 1114 and second fixing holes 1115 arranged in rows on different sides, and the positions of the first fixing holes 1114 and the second fixing holes 1115 are staggered. Meanwhile, it can be seen that the second frame assembly 112 and the third frame assembly 113 are also provided with the first fixing holes 1114 and the second fixing holes 1115 which are identical to the first frame assembly 111. These fixing holes may also be used to cooperate with rubber pins for fixing. Fix through the rubber nail, both can realize exempting from the dismantlement or the installation of instrument, also can play isolated effect to the vibrations between the part. In order to increase the overall structural rigidity of the frame structure, as shown in fig. 3, a transverse auxiliary connecting plate 114 is provided between the front panel unit 16 and the corresponding two third frame units 113.

Similarly, as shown in fig. 2, the top plate unit 13 includes a top plate body 131 and a plurality of fan mounting brackets 132 disposed on the top plate body 131, the top plate body 131 is fixed on the two opposite second frame assemblies 112, and has a hollow portion in the middle, and the fan mounting brackets 132 are fixed on the hollow portion in the middle of the top plate body 131.

Different from the conventional arrangement mode, in the invention, the space position of the display card is in the position which is easy to radiate heat in the air duct, and can actually extend to the inner space of the whole case, so that in other words, as long as the length of the display card is not more than the size of the case, the upgrading or the extension of the display card can be realized. Similarly, for the upgrade of the power supply, unlike the prior art, as shown in fig. 3 and 4, the mid-mounting board unit 17 may be actually divided into a motherboard mounting portion 171 and a power supply mounting portion 172 with different specific specifications, and both the motherboard mounting portion 171 and the power supply mounting portion 172 have a hollow portion to increase the heat dissipation level. In addition, since the power supply is no longer located at the corner of the chassis, but is located at the center of the chassis in parallel with the main board, the volume of the chassis is almost not limited, and for convenience of wiring, as shown in the figure, the power supply mounting portion 172 is further provided with a plurality of first wiring holes 174. Of course, in order to facilitate the connection of the power supply to the external power plug, as shown in fig. 1, a power adapter unit 19 electrically connected to the power supply is disposed on the back board unit 12.

The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the scope of the present invention is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present invention, and such modifications and equivalents should also be considered as falling within the scope of the present invention.
