3 is a partial exploded perspective view of the display module and the fixing mechanism shown in FIG. 2.

4 is a partial exploded perspective view of the fixing mechanism of the embodiment of the present invention.

Referring to FIG. 1 to FIG. 3 , the electronic device 100 of the embodiment of the present invention is a tablet computer including a first housing 11 , a second housing 12 , a display module 13 , and a fixing mechanism 20 for fixing the display module 13 .

The first housing 11 is a rectangular frame that defines a rectangular opening 112 for the display module 13 to present an image. The second housing 12 is fastened to the first housing 11 to form an accommodating space (not shown). The display module 13 is received in the accommodating space.

The display module 13 includes members (not shown) such as a liquid crystal cell, a light guide plate, a reflection plate, a diffusion plate, and the like, and a frame 131 that fixes these members. Four lugs 1312 are formed on the outer side of the outer frame 131, and each of the lugs 1312 defines a first mounting hole 1313. The specific structure and function of the display module 13 are well known to those skilled in the art, and are not described herein.

Referring to FIG. 4 , the fixing mechanism 20 is configured to fix the display module 13 in the accommodating space formed by the first housing 11 and the second housing 12 . The fixing mechanism 20 includes a frame body 21 and two pairs of brackets 22 fixedly coupled to the frame body 21.

The frame 21 is fixedly coupled to the second housing 12. The frame body 21 is substantially rectangular and includes two first frames 212 and two second frames 213 disposed opposite to each other. The first frame 212 and the second frame 213 together define a rectangular receiving hole 214. The receiving hole 214 has a display ratio The periphery of the module 13 is slightly larger in size to accommodate the display module 13 therein.

The two pairs of brackets 22 are respectively welded to the bottom surface of the first frame 212 of the frame 21, and jointly fix and support the display module 13.

Each bracket 22 is a bent piece body, and includes a fixing portion 221 welded to the frame body 21, a mounting portion 223 fixedly connected to the display module 13, and a connecting portion 224 connecting the fixing portion 221 and the mounting portion 223. The mounting portion 223 extends into the frame body 21 and has a substantially flat plate shape and is substantially parallel to the frame body 21.
