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, and four brackets fixedly disposed on the sidewall of the first housing, the four brackets are respectively disposed on the a fourth side of the side wall, the first housing includes a bottom plate and a side wall extending from an edge of the bottom plate, the top end of the side wall is formed with a welding surface, and an edge of the second housing abuts the welding surface, the bracket The upper limit portion is extended, and the limit portion is connected to the second housing.

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

The electronic device housing of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

Referring to FIG. 3 to FIG. 5 , the electronic device housing 30 of the first embodiment of the present invention includes a first housing 31 and a second housing 32 that are connected by soldering, and connects the first housing 31 and the second housing. The first bracket 33 and the second bracket 34 of the body 32. In this embodiment, the first housing 31 is a bottom case, and the second housing 32 is a top cover. The electronic device housing 30 includes four first brackets 33 and two second brackets 34. The four first brackets 33 are distributed at the corners of the first housing 31, and the second brackets 34 are distributed at the first two adjacent positions. The brackets 33 are disposed opposite each other.

The first housing 31 includes a bottom plate 311 and a side wall 312 extending from an edge of the bottom plate 311. A welding surface 3112 is formed at the top end of the side wall 312. In this embodiment, the bottom plate 311 is substantially rectangular, and the side wall 312 is a curved side wall.

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 bottom surface of the second housing 32 is provided with a plurality of limiting holes (not labeled) distributed around the mounting hole 320. The edge of the second housing 32 abuts the soldering surface 3121 of the curved sidewall 312.

The first bracket 33 includes a first welded portion 331 and a first limiting portion 332 extending from one end of the first welded portion 331 . The first 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 formed by a substantially vertical extension of one end of the first welding portion 3311, A welded section 3311 and a second welded section 3312 are both curved sheets. The first limiting portion 332 includes a body 3321 and a limiting piece 3322 extending from the first end of the body 3321 away from the first welding portion 331 . In the present embodiment, the body 3321 is substantially arcuately arched, and the limiting piece 3322 is in the shape of a rectangular plate.

The second bracket 34 includes a second welded portion 341 and is extended by one end of the second welded portion 341 The second limiting portion 342. The second 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. The second limiting portion 342 includes a body 3421 and a limiting piece 3422 extending from the second end of the body 3421 away from the second welding portion 341 . In the present embodiment, the body 3421 is substantially arcuately arched, and the limiting piece 3422 is in the shape of a rectangular plate.
