Description

Electronic device housing

The present invention relates to an electronic device housing, and more particularly to an electronic device housing formed by soldering.

Referring to FIGS. 1 and 2 , an electronic device housing 10 includes a bottom case 11 and a top cover 12 . The edge of the top cover 12 is joined to the bottom case 11 by welding. During the welding process, the top cover 12 and the bottom case 11 are fixed together by a positioning jig (not shown), and then placed in a welding device (not shown) for welding.

However, when the top cover 12 and the bottom case 11 are clamped by using the positioning jig, since the welded portion of the bottom case 11 and the top cover 12 is smoothly abutted, the bottom case 11 is easily lost and deviates from the welding position, thereby causing the bottom case 11 and the top cover 12 to be Misalignment occurs between them, affecting the appearance of the electronic device housing after soldering. In addition, since the bottom case 11 and the top cover 12 are welded only at the edge portion, the connection strength between the bottom case 11 and the top cover 12 is also relatively low.

In view of the above, it is necessary to provide an electronic device housing that does not lose stability during mounting and has a high connection strength after soldering.

An electronic device housing includes a first housing, a second housing, four brackets and a fixing member, the first housing and the second housing being welded together, the first housing comprising a bottom plate and extending from an edge of the bottom plate a sidewall, a top surface of the sidewall is formed with a soldering surface, an edge of the second housing abuts the soldering surface, and the four brackets are fixedly disposed on the first housing side Each of the brackets includes a welded portion and a fixing portion extending from one end of the welded portion, and the welded portion is welded to a corner portion of the side wall, and the fixed portion is connected to the second housing by a fixing member.

When the electronic device housing is soldered, the first housing and the second housing are mutually positioned by the bracket and the fixing member, and the first housing does not lose stability and moves relative to the second housing, so that the soldered electronic device can be The housing has a preferred appearance. In addition, the first housing and the second housing are not only connected by soldering but also connected to each other by the bracket and the fixing member, thereby increasing the connection strength between the two.

The second housing 32 is substantially rectangular, and has a mounting hole 320 for receiving a display screen (not shown) at the center thereof, and a plurality of through holes 321 are defined at the edge portion. The edge of the second housing 32 abuts the soldering surface 3121 of the sidewall 312 of the first housing 31.

The first bracket 33 includes a welded portion 331 and a fixed portion 332 formed by extending one end of the welded portion 331. The welding portion 331 is adapted to the side wall 312 of the corner portion of the second housing 32, and includes a first welding portion 3311 and a second welding portion 3312 extending substantially perpendicularly from one end of the first welding portion 3311, the first welding The segment 3311 and the second welded segment 3312 are both curved sheets. The fixing portion 332 includes a supporting piece 3321 and a connecting piece 3322 extending perpendicularly from one end of the supporting piece 3321. The connecting piece 3322 is provided with a screw hole 3324. In the present embodiment, two fixing portions 332 are formed on the welded portion 331 , and the supporting piece 3321 and the connecting piece 3322 are both in a rectangular sheet shape.

The second bracket 34 includes a welded portion 341 and a fixed portion 342 formed by extending one end of the welded portion 341. The soldering portion 341 is disposed at the center of the opposite sidewalls 312 of the second housing 32, and is in the shape of a curved sheet that fits the sidewall 312.
