As a further improvement of the utility model, an installation opening is provided on the upper cover, and the inner wall around the installation opening is bent downward to form a number of support arms extending inwardly, and a signal module is installed on the installation opening. A plastic cover is clamped on the support arm.

As a further improvement of the utility model, several limiting holes are opened on the upper cover, and a limiting bending bar bent to one side is arranged in the limiting holes.

The beneficial effects of the utility model are:

(1) By setting the snapping structure on the upper cover, it is convenient for snapping and assembling with the bottom case on the chassis, so that the assembly can be completed quickly. Compared with the traditional way of fixing with multiple screws, the assembly and disassembly are greatly improved. The convenience and speed are conducive to the realization of automatic assembly;

(2) By setting the air convection heat dissipation hole group on the upper cover, it can achieve the effect of air flow heat conduction and heat dissipation, prevent a large amount of heat from being difficult to dissipate, and improve the heat dissipation effect of the chassis;

(3) With the setting of the plastic cover, the signal module can be set on the plastic cover. The plastic material has no shielding effect on the signal, so it plays the role of preventing signal shielding and ensuring the normal transmission of the signal.

The above is an overview of the technical solution of the utility model, and the utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Fig. 2 is a schematic diagram of the back structure of the utility model.

Detailed ways

In order to further explain the technical means and effects of the utility model to achieve the predetermined purpose, the specific implementation of the utility model will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

Please refer to Figure 1 and Figure 2, the embodiment of the utility model provides a multimedia navigation host chassis cover, including the cover body 2, the two ends of the cover body 2 are respectively bent to one side to form a number of upper card arms 24, and a protrusion 241 protrudes from the inner side of the upper arm 24.

In this embodiment, an opening 242 is respectively formed between two sides of the upper locking arm 24 and the upper cover body 2 .

The number of upper clamping arms 24 can be set according to specific needs. In this embodiment, the number of upper clamping arms 24 is two.

The upper cover of the host computer case provided in this embodiment can be used in conjunction with a bottom case with a special structure. Specifically, lower clamping arms matching the upper clamping arms 24 are respectively provided at both ends of the bottom case, and clamping holes for the protrusions 241 to be clamped are opened on the lower clamping arms. During assembly, as long as the upper arm 24 on the upper cover is aligned with the outer side of the lower arm on the bottom case, so that the convex point 241 on the upper arm 24 is engaged in the locking hole on the lower arm, you can quickly Completing the assembly, compared with the traditional way of fixing with multiple screws, the convenience and speed of assembly and disassembly are greatly improved.

At the same time, in order to improve the heat dissipation effect of the entire chassis, in this embodiment, a heat dissipation opening 21 is provided on the upper cover body 2 , and an air convection cooling hole group 22 is provided on the upper cover body 2 and around the heat dissipation opening 21 . At the same time, the middle part of the upper cover body 2 is bent downward to form a lower concave portion 23, the heat dissipation opening 21 is opened on the lower concave portion 23, and the air convection cooling hole group 22 includes openings on the lower concave portion 23 and located at the cooling opening 21. A plurality of cooling holes 221 around, and a plurality of air convection holes 222 opened on the upper cover body 2 and located around the lower concave portion 23 .
