The protective member is mounted on the outer side of the working body. And forming a receiving slot together with the body, the display panel is mounted on the inner side of the housing; the configurable < electronic device comprises the dustproof structure. The portable electronic device can effectively prevent dust by using a dust-proof structure between the protective member, the housing and the display panel, and using the deformation of the dust-proof structure to fill the tilting money board. When the impurities enter the _ panel, there is a wire to protect the display panel. [Embodiment] A preferred embodiment of the present invention provides a dustproof structure suitable for mobile electronic devices such as mobile phones and personal digital assistants (PDAs). Please refer to FIG. 2 and the portable electronic device 100 including a housing 10, a protection member 2α, a dustproof structure 30, a display panel 40, and a circuit board 501. The protection member 20, the dustproof structure 3, the display panel 40, and the circuit board 50 are disposed in parallel with each other and are mounted on the casing 1〇. The housing 10 includes a first surface π and a second surface 12. The first surface Η is provided with a substantially rectangular mounting groove, and a mounting hole 112 having a substantially rectangular shape and penetrating the first surface and the second surface 12 is disposed between the middle portions of the mounting groove lu. The second surface 丨2 is disposed away from the first surface n, and the two sides are respectively provided with the holding portions 121. The holding portion 121 has a substantially rectangular sheet shape and is disposed substantially perpendicular to the second surface 12. The holding portion i2i may be integrally formed with the housing 10, or may be fixed to the second form number A0101 苐 4 pages / 15 pages 0992060528-0 201216809 surface 12 by welding or the like. [0011] Referring to FIG. 2 together, the protection member 20 is substantially rectangular and can be made of a transparent material such as glass or p〇ly methyl methacrylate (PMMA). The protection member 2 is mounted in the mounting slot, and closes one side of the mounting hole 112 toward the first surface π, and forms a substantially rectangular receiving groove 122 with the mounting hole 112. The protection member 2 is used to protect the display panel 40 to prevent the display panel 4 from being scraped during use. [0012] The dustproof structure 30 is installed in the accommodating groove 1: 22, and includes a dustproof portion 31 and a second affixing portion. 32. The dustproof portion 31 has a substantially rectangular frame shape and can be made of a material such as foam. The dustproof portion 31 includes a second dustproof strip 311 and two second dustproof strips 3'2. The two first dust-proof strips 311 and the two second dust-proof strips 312 are respectively in a rectangular strip shape. The two first dust-proof strips 311 are opposite to each other and disposed opposite to each other. The second dust-proof strips 312 are disposed on the first dust-proof strip 311. The first dust strip 311 is disposed on the side and perpendicularly. A substantially rectangular gap 3111 is disposed in each of the first dust-proof strips 311 adjacent to the two sides of the second dust-proof strip 312. An opening 3121 corresponding to the notch 3111 is disposed on each of the two sides of the first dust-proof strip 312 adjacent to the first dust-proof strip 311. The first dust-proof strip 311 and the second dust-proof strip 312 are sequentially joined end to end by the gaps 3111 of the first dust-proof strip 311 and the corresponding openings 3121 of the second dust-proof strip 312, thereby forming the rectangular frame shape. body. The two pasting portions 3 2 are each a rectangular frame body. The specific shape and structure thereof correspond to the dustproof portion 31. The two adhesive portions 3 2 are respectively fixed to both sides of the dustproof portion 31 to sandwich the dustproof portion 31 therein. The opposite surfaces of the adhesive portion 32 have adhesiveness, wherein the adhesive portion 32 facing the receiving groove 122 is used to paste the dustproof portion 31 to 099134658. Form No. A0101 Page 5 / Total 15 Page 0992060528-0 In the 201216809 4 slot 122, the other portion 32 is used to attach the dustproof portion 31 to the display panel 4G. The money protection member 2 () and the display panel are assembled from the dustproof portion 31. The gap between the protective member 2G and the display panel 4〇 is formed to form a closed area 41, so that impurities such as dust from the outside can be prevented from entering the closed area, thereby effectively protecting the display panel 40. [0014] The display panel is a liquid crystal display panel, which is disposed between the circuit board 50 and the dustproof structure 30. The circuit (10) includes a plate body 51 and an extension portion 52. The plate body 51 is substantially rectangular, and the extending portion 52 is formed by extending on both sides of the circuit board 5, and the rectangular plate-like protrusions in which the dam plate bodies 51 are in the same plane are disposed on the circuit board 5G at intervals. On both sides. The extending portion 52 corresponds to the holding portion, and can be abutted against the holding portion 121 to assemble the circuit board 50 to the casing 1 and further fix the display panel 4Q. The display panel 4G provides an electrical connection. Referring to FIG. 3 and FIG. 4 together, when the portable electronic device 1 is assembled, firstly, the protective member 20 is attached to the mounting groove 141, and one side is coated with a viscous material such as glue, and glued with glue. The protection member 2〇 of the branch is relatively firmly mounted on the housing ίο. At this time, the protection member 20 closes one side of the mounting hole 112 toward the first surface 11 and forms the above-mentioned accommodating groove 122 together with the mounting hole 112. Then, one of the adhesive portions 32 is affixed into the accommodating groove 122 to fix the dustproof structure 30 in the accommodating groove 122. The display panel 4 is aligned with the other bonding portion 32 to adhere the display panel 4A to the other side of the dustproof structure 3A. Finally, the extending portion 52 of the circuit board 50 is aligned with the holding portion 121 such that the extending portion 52 and the holding portion 121 abut each other to assemble the circuit board 5G to the housing 1Q, and further Solid (four) display panel 099134658 Form No. A0101 Page 6 / Total 15 Page 0992060528-0 201216809 40. When the display panel 40 is mounted on the dustproof structure 30, the dustproof structure 30 is deformed by the pressing action of the display panel 40 and the protective member 20, thereby filling the gap between the notch 3111 and the opening 3121. The display panel 40 is effectively protected by further preventing impurities such as dust from entering the casing 10 and the enclosed region 41 from the side of the dustproof structure 30. [0016] It can be understood that the dust-proof structure 30 of the present invention is assembled into a rectangular frame by sequentially connecting the two first dust-proof strips 311 and the second dust-proof strips 312 end to end, and has a simple structure. The utilization rate of the foam can be effectively improved, and the overall manufacturing cost of the portable electronic device 100 can be reduced. It is obvious that the portable electronic device 100 of the present invention is provided with a dustproof structure 30 between the protective member 20, the housing 10 and the display panel 40, and is deformed by the dustproof structure 30 to fill the protection. The gap between the member 20 and the display panel 40, thereby forming the closed region 41, can effectively prevent impurities such as dust from entering the display panel 40, thereby effectively protecting the display panel 40. [0017] In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
