Detailed Description
In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention to those skilled in the art. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. Furthermore, it is to be understood that the invention is not to be limited to the specific embodiments described. Rather, any combination of the following features and elements, whether related to different embodiments or not, is contemplated to implement the present invention. Thus, the following aspects, features, embodiments and advantages are merely illustrative and should not be considered elements or limitations of the claims except where explicitly recited in a claim.
Fig. 1 illustrates a three-dimensional schematic view of an electronic device housing in accordance with one or more embodiments of the present disclosure. Fig. 2 illustrates a three-dimensional schematic view of a housing in accordance with one or more embodiments of the present invention.
Fig. 3 illustrates a three-dimensional schematic view of a cover plate in accordance with one or more embodiments of the present invention. Referring collectively to fig. 1-3, the electronic device 10 includes a housing 100. In one or more embodiments, the electronic device 10 may be a smart antenna. The housing 100 includes a case 110 and a cover plate 120.
The housing 110 is used to accommodate the printed circuit board 200. The housing 110 has an opening 111 with a chamfered corner and an engagement groove 112 located in a chamfered corner region. In one or more embodiments, the housing 110 may be fabricated from multiple pieces. For example, the upper casing and the lower casing are combined. In one or more embodiments, the housing 110 may be integrally formed. The housing 110 may be made of one or more insulating materials. For example, the housing 110 may be made of plastic.
The cover plate 120 is used to cover the opening 111. The cover plate 120 has an engaging portion 121 at a corner corresponding to the corner cut. When the cover plate 120 covers the opening 111, the engaging portion 121 is inserted into the engaging groove 112, so that the corner of the cover plate 120 is engaged with the housing 110. In one or more embodiments, the cover plate 120 is provided with screw holes 123 at portions of a plurality of corners other than the corner where the engaging portion 121 is located. The cover plate 120 is fixed to the case 110 by screws or the like at corners other than the corner where the engaging portion 121 is located. In one or more embodiments, the cover plate 120 may be made of metal.
One corner of the cover plate 120 is fixed by the engaging portion 121 and the engaging groove 112 of the housing 110, which has good stability. Further, even if the screw for fixing the cover plate 120 is loosened after the cover plate 120 is assembled to the housing 110, the engaging portion 121 restricts the movement of the cover plate 120 in the vertical direction of the surface on which the opening 111 is located, and thus noise is less likely to be generated.
fig. 4 illustrates a schematic cross-sectional view of a snap-fit portion of a cover plate in accordance with one or more embodiments of the present disclosure. Referring to fig. 4, the engaging portion 121 includes a first bending portion 121a and a second bending portion 121 b. The first bending portion 121a is connected to the main body of the cover plate 120, and the second bending portion 121b is connected to the first bending portion 121 a. The included angle α between the first bent portion 121a and the body of the cover plate 120 is between 90 ° and 150 °. For example, the included angle α may be 120 °. An included angle β between the second bending portion 121b and the first bending portion 121a is smaller than the included angle α. For example, when the angle α is 120 °, the angle β may be 113 °.
In one or more embodiments, the thickness h of the engaging portion 121 is smaller than the distance from the engaging groove 112 to the pcb 200. Thus, when the cover plate 120 is mounted on the housing 110, the engaging portion 121 does not press against the printed circuit board 200.
In one or more embodiments, the length 1 of the engaging portion 121 is less than the distance from the engaging groove 112 to the printed circuit board 200. Thus, during assembly, when the engaging portion 121 is inserted into the engaging groove 112, the engaging portion 121 does not touch the printed circuit board 200, thereby preventing the printed circuit board 200 from being scratched by the cover plate 120.
In one or more embodiments, the cover plate 120 also has a heat conducting portion 122 that protrudes inward of the housing 110. The heat conduction portion 122 is used to conduct heat of the printed circuit board 200 for heat dissipation. Since the cap plate 120 may be made of metal, the entire cap plate 120 may serve as a heat dissipation component of the printed circuit board 200. In one or more embodiments, a thermally conductive elastomer, such as a thermally conductive gel GF1500, may be disposed between the thermal conductor portion 122 and the printed circuit board 200. In one or more embodiments, the heat conducting portion 122 may be formed by stamping the cover plate 120. In one or more embodiments, the cover plate 120 has one or more screw holes 123 at the edge of the heat-conducting portion 122. The heat conducting portion 122 or the heat conducting elastic body can be stably attached to the printed circuit board 200 through the screw hole 123 and the screw at the edge of the heat conducting portion 122, so as to stably dissipate heat for the printed circuit board 200.
Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited thereto. Various changes and modifications can be made by one skilled in the art without departing from the spirit and scope of the invention, and the scope of the invention is to be determined by the appended claims.
