The solution of the present invention is to arrange the display module and/or the control module on the upper cover 100, and the upper cover 100 can directly perform display and control, so that the upper cover 100 has both protection function and display control function.

The specific solution is that the upper cover 100 includes a cover plate 1 and a housing, the housing has an accommodating space for placing the display module and/or the control module, after the display module is placed in the accommodating space, the cover plate 1 is configured at an upper opening of the accommodating space, so that the display panel of the display module is combined with the cover plate 1, and a display area is formed at a corresponding position of the cover plate 1; similarly, after the control module is placed in the accommodating space, the cover plate 1 is disposed at the upper opening of the accommodating space, so that the control panel of the display module is combined with the cover plate 1 to form a control area at a corresponding position of the cover plate 1.

The display area and the control area can not be formed independently by cutting the cover plate 1, but can be displayed and controlled through the cover plate 1, so that the integrity of the cover plate 1 is ensured, and the aim of beautifying the appearance of the air is fulfilled.

Since the display area and/or the control area need to be assembled with the cover plate 1 to form a corresponding area, the upper portion of the receiving space has an opening, the receiving space has at least one upward opening, and the display module and/or the control module form a display and control area with the cover plate through the opening.

By technical means, the display module and the control module can be integrated into a whole, and the integrated display module and the control module are placed into the accommodating space and are referred to as a display control module 4. The display module and the control module can be respectively disposed in the housing of the upper cover 100 in the above manner, and for convenience of description, the display control module 4 is taken as an example for illustration.

In the assembling process, the display control module 4 needs to be put in from the opening at the bottom of the accommodating space, and after the display control module 4 is put in the accommodating space, in order to prevent the display control module 4 from falling off or shifting, the display control module 4 needs to be fixed in the accommodating space, so that the subsequent assembling process is facilitated.

The display control module 4 is detachably disposed in the space 21.

Fig. 2 is an exploded view of the upper cover structure, the housing is composed of an upper housing 2 and a lower housing 3, and the upper housing 2 and the lower housing 3 are arranged as the housing, because some other parts are arranged inside the housing, and need to be installed or arranged inside the housing during the assembly process, the upper housing and the lower housing can be arranged to seal the housing after the parts are assembled, so that the overall appearance is formed, and the parts are not exposed. This is one embodiment of the housing.

The above description is made by taking the arrangement of the case 2 and the lower case 3 as an example.

As shown in fig. 3, the upper case 2 has a first opening 21, the first opening 21 is used for forming the accommodating space for accommodating the display control module 4, and an outlet 22 is disposed at one side of the first opening 21, so that the display control module 4 is electrically connected to a computer board or other structures.
