DETAILED DESCRIPTION OF THE INVENTION
To make the object, structure, features, and functions of the present invention more comprehensible, the present invention is illustrated in detail below with reference to the embodiments.
FIG. 1A and FIG. 1B are schematic stereograms of the first embodiment according to the present invention. As shown in the figures, the fixing boss structure 100 the present invention is disposed on a housing 200 having a plurality of blind holes 210, wherein the material of the housing 200 may be either metal material or plastic material. The fixing boss structure 100 includes a post 110 and a pressing part 120 that disposed at one end of the post 110, wherein the post 110 is a cylindrical structure, but those skilled in the art may change the design of the post 110 as a post with polygonal structure, which is not limited by the embodiment disclosed in the present invention. A combining hole 111 is opened along the axial position inside the post 110, which is used to be combined or disassembled with fixing components (not shown), e.g., fixing elements such as pin or bolt, so as to facilitate the user to add electronic component parts at the preset position. The outside diameter of the pressing part 120 is larger than the inside diameter of the blind hole 210, and the size and material hardness of the pressing part 120 is larger than those of the blind hole 210, thus the pressing part 120 is forced to be pressed and fixed inside the blind hole 210, such that the post 110 is steadily embedded and fixed on the housing 200 without being separated from it.
As shown in FIG. 1A, a screw thread 1111 is disposed on the inner side of the combing hole 111 of the post 110, so that the user may lock the bolt on the post 110. The surface of the pressing part 120 engaged with the blind hole 210 is a rough surface, so as to increase the friction between the blind hole 210 and the surface, such that the post 110 is not easy to be separated from the housing 200. The rough surface of the pressing part 120 may be formed by sand blasting process or other mechanical treatment methods. In addition, during the process of manufacturing, the fixing boss structure 110 is embedded and fixed inside the housing 200 by a tight fit manner, and a rust proof treatment is performed on the surface of the fixing boss structure 110, so as to increase the appearance quality and the service life of the fixing boss structure 110.
FIG. 2A and FIG. 2B are schematic stereograms of the second embodiment according to the present invention. As shown in the figures, the pressing part 120 has a surrounding conical gear 121 arranged in a fixed spacing around the post 110. The conical gear 121 having a tip structure is forced to be pressed inside the blind hole 210, and the tip portion and the outer edge of the blind hole 210 are deformed to be engaged with each other, so as to significantly increase the bonding strength of the pressing part 120 with respect to the blind hole 210 having lower hardness. As for the user, it is easier to force the pressing part 120 to be pressed and embedded inside the blind hole 210.
FIG. 2C is a partially enlarged schematic view of the surrounding conical gear 121 according to the second embodiment of the present invention. As shown in the figure, a zigzag texture 1211 may further be disposed at the tip of the surrounding conical gear 121, such that the friction of the pressing part 120 for engaging the blind hole 210 is increased, and the bonding strength between the post 110 and the housing 200 is increased, so as to avoid the problem of shelling because of insufficient strength.
In the present invention, the post is pressed to be disposed inside the blind hole of the housing by a tight fit method, the disposition position of the fixing boss structure of the present invention is not limited by the circuit layout of the circuit board, and the bonding strength between the fixing boss and the housing is preferable and complies the current demand for the volume of the electronic device as being light and thin.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
