1. Technical Field
The present disclosure relates to a fastening assembly and an electronic device using the fastening assembly.
2. Description of Related Art
Electronic devices typically define fastening assemblies allowing external ornaments to be hung from. The fastening assembly may be formed by defining a corner hole in the housing of the electronic device. A cord connecting the ornaments can be hung through the corner hole. However, the hung ornament can be difficult to handle.
Therefore, there is room for improvement within the art.
Many aspects of the disclosure can be better understood with reference to the following figures. The components in the figures are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The housing 10 defines a hole 102 in an end wall 101 of the housing 10. The housing 10 defines an inside bottom surface 103. A mounting portion 104 is enclosed by three sidewalls vertically protruding from the inside bottom surface 103, and adjacent to the hole 102.
The fastening assembly 20 includes a fastening block 21, at least one elastic element 22, and a release element 23. In the exemplary embodiment, there are two elastic elements 22.
The release element 23 includes a pressing portion 230, and two guide columns 231, a stopper column 232, two fastening columns 233 respectively protruding from the inner surface of the pressing portion 230, and towards the fastening block 21. The two guide columns 231 are located at the two opposite sides of the pressing portion 230. The stopper column 232 is located near the center of the pressing portion 230. Each fastening column 233 is located between each guide column 231 and stopper column 232 (see
Each guide column 231 further defines an wedge-shaped portion 234 at the junction of the guide column 231 and the pressing portion 230. The two wedge-shaped portions 234 may latch the inner portion of the end wall 101 against the housing 10 to prevent the release element 23 from completely popping out of the hole 102 under the elastic expansion of the elastic elements 22.
The pressing portion 230 has a shape and a size mating with the shape and size of the hole 102, so the pressing portion 230 can pass through the hole 102 and partially latch in the housing 10.
The fastening columns 233 are shorter than the guide columns 231 and the stopper column 232. Each fastening column 233 fastens around an end of each elastic element 22.
The fastening block 21 defines a sliding groove 212 on a surface 211 of the fastening block 21. A flange 213 pointing towards release element 23 is defined at one end of the sliding groove 212, and the other end of the sliding groove 212 defines an opening. A āVā shaped stopper portion 214 is defined on the sliding groove 212, adjacent to the flange 213. The stopper portion 214 includes two stopper arms 215, 216. The stopper arms 215, 216 respectively define a guide surface 217 (see
The flange 213 defines a first recessed portion having an arcuate closed end 218 and a second recessed portion having an arcuate closed end 219 at the two shoulders of the flange 213. The arcurate closed end 219 has a larger radius than the radius of the arcuate closed end 218. The first recessed portion having an arcuate closed end 218 is opposite to the inner end of the stopper arm 215. The second recessed portion having an arcuate closed end 219 is opposite to the outer end of the stopper arm 216 (see
The surface 211 of the fastening block 21 further defines an arcuate recessed section 220. The arcuate recessed section 220 has an arc mating with the arc of the pressing portion 230, allowing the pressing portion 230 to be partially received in the recessed section 220. A step is defined and connects the recessed section 220 and the sliding groove 212. The step can restrict the movement of the pressing portion 230 to the fastening block 21.
The pressing portion 230 defines a rope hole 235 for hanging ornaments. Two arcuate notches 236 are respectively defined at the two ends of the rope hole 235 for hanging the ornaments easily. The arcuate notches 236 can decorate the pressing portion 230.
The space between the out surfaces of the two guide columns 231 matches with the width of the mounting portion 104. When the pressing portion 230 is partially received in the recessed section 220 of the fastening block 21, the two guide columns 231 respectively contact the surface 211 at the regions adjacent to the sliding groove 212. While the pressing portion 230 is pressed to be completely received in the recessed section 220, or the pressing portion 230 partially pops out of the housing 10, the two guide columns 231 respectively slide on the surface 211 to guide the movement of the pressing portion 230.
The stopper column 232 defines a stopper pin 237 at the end of the stopper column 232. The stopper pin 237 vertically extends downward from the main body of the stopper column 232. The stopper column 232 and the stopper pin 237 are both made of resilient resins.
After the ornaments are fastened to the fastening assembly 20, the pressing portion 230 of the release element 23 is pressed to the mounting portion 104. The two elastic elements 22 are gradually compressed. The stopper column 232 gradually moves to the stopper portion 214 and then contacts the guide surface 217 of the stopper arm 215. Since the stopper pin 237 and the stopper column 232 are resilient, the stopper pin 237 can further move along the guide surface 217 of the stopper arm 215 when the pressing portion 230 is further pressed and finally moves around the end of the stopper arm 215 and arrives at the first recessed portion having an arcuate closed end 218. When the pressing to the pressing portion 230 is released, the stopper pin 237 latches in the stopper portion 214, thereby the pressing portion 230 is completely mounted in the housing 10.
As discussed above, in the embodiment, ornaments can be conveniently and quickly fastened to the fastening assembly 20.
It is believed that the exemplary embodiment and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the disclosure or sacrificing all of its advantages, the examples hereinbefore described merely being preferred or exemplary embodiment of the disclosure.
