The middle frame can be used for supporting and fixing the display module. The display module can be used for displaying image information.

Wherein the middle frame comprises a frame part 1 for forming the side wall of the electronic equipment, and a supporting structural member 2 is arranged on the inner surface of the frame part 1. The display module comprises a display screen 3 and a light-transmitting cover plate 4 covered on the display screen 3. The display module is covered on the middle frame, and the supporting structural member 2 is used for limiting the light-transmitting cover plate 4 to be in contact with the inner surface of the frame part 1; wherein, the adhesive 6 is filled between the light-transmitting cover plate 4 and the inner surface of the frame part 1 and between the light-transmitting cover plate 4 and the supporting structural member 2.

When the liquid glue is filled into the glue dispensing gap 5, the glue cannot overflow, and the design can ensure that the glue path has certain thickness and uniformity, so that the display module is stably assembled on the middle frame.

In the conventional assembly process of the display module of the electronic device, referring to fig. 1, although the glue dispensing gap 5 is preset between the middle frame and the display module, no structure which may be used for supporting is designed between the side portion of the display module and the middle frame, so that the situation that the glue dispensing gap 5 becomes smaller easily occurs in the assembly process of the display module due to the action of pressure, and poor phenomena such as glue overflow and falling easily occur, or poor tightness and poor connection stability between the display module and the middle frame can be caused due to the glue overflow.

In addition, in the dispensing sealing of the display module and the middle frame, the supporting structural member is positioned in the area filled with the adhesive (such as glue) and cannot be exposed, so that the appearance quality of the electronic equipment cannot be affected.

Therefore, in the embodiment of the application, the supporting structural member 2 is additionally arranged on the middle frame, so that the phenomena of overflow, falling off and the like of glue in dispensing sealing can be avoided, the phenomena of poor tightness between the display module and the middle frame and poor connection stability of the display module and the middle frame can be avoided, and the defects in the prior art are overcome.

Finally, the display module can be stably fixed and adhered to the middle frame, and the sealing performance between the display module and the middle frame can be improved.

In an alternative example of the application, see fig. 5, the device housing 7 of the electronic device has four side walls, i.e. the rim portion 1 has four side portions, wherein at least two of the support structures 2 are provided on the inner surface of each side portion. Thus, the support for the display module is stable.

Of course, more than two of said support structures 2 may be provided on each side. Among these, it is preferable that a plurality of the support structures 2 are uniformly arranged.

In an alternative example of the present application, referring to fig. 2 to 4, the supporting structure 2 is a protrusion structure that is higher than the inner surface of the frame portion 1. The protruding structure can be used for forming a stable dispensing gap 5 with a size which is not easy to change between the display module and the middle frame, so that an adhesive 6 (such as glue) can be filled between the transparent cover plate 4 and the inner surface of the frame part 1 and between the transparent cover plate 4 and the supporting structural member 2.

The cross section of the protruding structure can be in a regular shape such as arc, rectangle, trapezoid and the like. Of course, other shapes are also possible, as long as the display module can be stably supported, and the display module can be flexibly adjusted according to actual needs by a person skilled in the art, which is not limited by the present application.
