The electronic device of the present invention can be an electronic device such as a computer host, a mobile phone, an MP3, a digital photo frame, a liquid crystal display, and a remote controller. In the present embodiment, the electronic device 100 will be described by taking a computer host as an example. Referring to FIGS. 1 and 2 , the electronic device 100 includes a housing 20 , a light guide post 30 , and a bonding member 50 . The housing 20 and the light guide post 30 are integrally fixed by the adhesive member 50. In order to save space, other components of the electronic device 100, such as a circuit board disposed in the housing 20, are not described.

Referring to FIG. 3 together, the housing 20 is substantially square and includes a bottom wall 21, a peripheral wall 23 extending from the edge of the bottom wall 21 toward one side thereof, and a top wall 25 opposite the bottom wall 21. The peripheral wall 23 includes an inner side surface 231 and an outer side surface 233 opposite to the inner side surface 231. A mounting hole 235 is formed through the outer side surface 233 to mount the light guiding rod 30. The mounting hole 235 is a stepped hole having an annular positioning surface 2351 facing the inner side of the housing 20. The top wall 25 is formed to extend inward from the one end of the peripheral wall 23 away from the bottom wall 21. Opened in the middle of the top wall 25 The opening allows the bottom wall 21, the peripheral wall 23 and the top wall 25 to define a receiving space 251 having an opening.

Referring to FIG. 4 to FIG. 6 together, the light guide column 30 includes a light guiding portion 31, a fixing portion 33, and a connecting portion 35 connecting the light guiding portion 31 and the fixing portion 33. The light guiding portion 31 is partially mounted in the mounting hole 235 of the housing 20, and includes a main body 311 and a flange 313 disposed around a substantially intermediate portion of the main body 311. The body 311 is substantially cylindrical and includes an outer end surface 3111 adjacent to the outer side surface 233 of the housing 20 and an inner end surface 3113 opposite the outer end surface 3111. The flange 313 forms a fitting surface 3131 corresponding to the positioning surface 2351 of the mounting hole 235 adjacent one end of the outer end surface 3111. The distance from the mounting surface 3131 to the outer end surface 3111 is the same as the distance from the positioning surface 2351 to the outer side surface 233 of the peripheral wall 23 such that the outer end surface 3111 is flush with the outer side surface 233 of the peripheral wall 23. The fixing portion 33 is provided around the light guiding portion 31, which is substantially square. A through hole 331 is defined in a middle portion of the fixing portion 33, and the light guiding portion 31 protrudes toward the both ends through the through hole 331. The fixing portion 33 includes an adhesive surface 332 adjacent to the mounting surface 3131 and a top surface 333 opposite to the bonding surface 332. The connecting portion 35 includes four connecting arms 351 that are symmetrically disposed. The connecting arm 351 has elasticity. One end of each connecting arm 351 extends from the edge of the flange 313 of the light guiding portion 31, and the other end is connected to the edge of the through hole 331 of the fixing portion 33. In the present embodiment, the material of the light guiding rod 30 is PMMA (polymethyl methacrylate), and the connecting arm 351 and the light guiding portion 31 are integrally formed.

Referring to FIG. 2 and FIG. 3 again, the bonding member 50 is used to fix the fixing portion 33 of the light guiding rod 30 and the housing 20. The thickness of the bonding member 50 plus the distance from the positioning surface 2351 to the inner side surface 231 is smaller than the distance between the bonding surface 332 and the mounting surface 3131. In the present embodiment, the adhesive member 50 is a double-sided tape having a shape that matches the fixing portion 33 of the light guide post 30, and a avoidance hole 501 corresponding to the through hole 331 of the fixing portion 33 is opened at the intermediate portion. It will be understood that the adhesive member 50 can also be formed by solidification of liquid glue.

When assembling, the adhesive member 50 is first adhered to the inner side surface of the peripheral wall 23 of the casing 20, and the avoidance hole 501 is corresponding to the mounting hole 235 of the peripheral wall 23; and the light guiding portion of the light guiding column 30 is further disposed. 31 is inserted into the mounting hole 235 at one end of the mounting surface 3131, so that the mounting surface 3131 is correspondingly engaged with the positioning surface 2351 of the mounting hole 235, so that the fixing portion 33 and the bonding member 50 are correspondingly bonded, thereby guiding the light guiding column 30 and the shell. The bodies 20 are fixed together.

Since the electronic device 100 of the embodiment of the present invention uses the positioning surface 2351 on the peripheral wall 23 to position the light guiding column 30 together with the mounting surface 3131 of the light guiding column 30, since the positioning surface 2351 can be more accurately sized by the opposite inner side surface 231, the outer surface 233 As the processing reference surface, the size of the positioning surface 2351 is also more accurate than the inner side surface 231, so that the assembly accuracy of the light guide bar 30 is higher, and the appearance of the electronic device 100 is better. In addition, the electronic device 100 fixes the light guide bar 30 by using a fixing portion 33 connected to the elastic connecting arm 351. When the thickness of the peripheral wall 23 is equal to or smaller than a predetermined standard thickness of the peripheral wall 23, the connecting arm 351 faces the peripheral wall 23. The elastic deformation occurs, and the fixing portion 33 is fixedly bonded to the bonding member 50. When the thickness of the peripheral wall 23 is slightly larger than the predetermined standard thickness of the peripheral wall 23, since the thickness of the bonding member 50 plus the distance from the positioning surface 2351 to the inner side surface 231 is smaller than the distance between the bonding surface 332 and the mounting surface 3131, the adhesion is made. A gap is still left between the connecting surface 332 and the bonding member 50, so that the connecting arm 351 is elastically deformed toward the peripheral wall 23, so that the fixing portion 33 and the bonding member 50 are fixedly bonded, thereby overcoming the processing of the housing 20. The error is such that there is no difference between the outer end surface 3111 of the light guiding rod 30 and the outer side surface 233 of the peripheral wall 23, which further improves the assembly precision of the light guiding rod 30, and the appearance of the electronic device 100 is better.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
