DETAILED DESCRIPTION
An embodiment of the electronic device and the hard disk drive mounting frame will now be described in detail below with reference to the drawings.
Referring to FIGS. 1-2, an electronic device 10 in accordance with an embodiment of the present disclosure is provided. The electronic device 10 includes a hard disk drive mounting frame 110, a hard disk drive 120 mounted on the hard disk drive mounting frame 110, and a printed circuit board 20 for supporting the hard disk drive mounting frame 110. The printed circuit board 20 includes a plurality of frame supporting poles 210 for supporting the hard disk drive mounting frame 110. Each frame supporting poles 210 defines a first screw hole 211 for a screw to pass through.
Referring also to FIG. 3, the hard disk drive mounting frame 110 include a bottom plate 111, two side plates 112 extending upwardly from the bottom plate 111, and two top plates 113 extending inwardly and horizontally from an upper end of the side plates 112. The side plates 112 and the top plates 113 define a plurality of hard disk drive supporting holes 114. Hard disk drive securing screws 130 pass through the hard disk drive supporting holes 114 to secure the hard disk drive 120 to the hard disk drive mounting frame 110. The bottom plate 111 defines a plurality of frame supporting holes 115. The frame supporting holes 115 are located directly under the hard disk drive 120 and covered by the hard disk drive 120. Frame securing screws 140 pass through the frame supporting holes 115 to secure the hard disk drive mounting frame 110 to the printed circuit board in outer environment. Each hard disk drive supporting hole 114 includes a first through hole 1141 and a second through hole 1142. The first through hole 1141 and the second through hole 1142 are communicated with each other. A diameter of the first through hole 1141 is larger than a diameter of the second through hole 1142. The frame supporting holes 115 are arranged in matrix. In this embodiment, a plurality of positioning rings 116 is formed on a bottom surface of the bottom plate 111. Each positioning ring 116 surrounds the frame supporting hole 115, and a diameter of the inner surface of the positioning ring 116 is larger than a diameter of the frame supporting hole 115. The position ring 116 is configured to position the hard disk drive mounting frame 110 when the hard disk drive mounting frame 110 is assembled to the printed circuit board 20. In positioning of the hard disk drive mounting frame 110, the frame supporting poles 210 of the printed circuit board 20 are received in the positioning rings 116. After that, the frame securing screws 140 pass through the frame supporting holes 115 and screws into the first screw hole 211 of the frame supporting pole 210.
The hard disk drive 120 defines a plurality of second screw holes 121 at side surfaces thereof. The second screw holes 121 are configured to be passed through by hard disk drive securing screws 130 positioned at the side plate 112 of the hard disk drive mounting frame 110. The hard disk drive 120 further defines a plurality of third screw holes 122 at an upper surface thereof. The third screw holes 122 are configured to be passed through by hard disk drive securing screws 130 positioned at the top plate 113 of the hard disk drive mounting frame 110.
The hard disk drive mounting frame 110 further includes a plurality of vibration pads 150. The vibration pads 150 are made of elastic materials. Referring also to FIG. 4, each vibration pad 150 includes a columned main body 151 and a central hole 152 passing through the main body 151. The main body 151 defines an annular groove 153 at outer surface thereof. The annular groove 153 is engaged with the second through hole 1142. The hard disk drive securing screws 130 pass through the central hole 152 and engage with the second screw holes 121 or the third screw holes 122 of the hard disk drive 120. In this embodiment, a diameter of the main body 151 is less than a diameter of the first through hole 1141, and larger than a diameter of the second through hole 1142. A diameter of an inner wall of the annular groove 153 is less than a distance of the connecting portion between the first through hole 1141 and the second through hole 1142. In assembling the vibration pad 150 to the hard disk drive mounting frame 110, the main body 151 of the vibration pad 150 passes through the first through hole 1141 to make the side plate 112 corresponding to the annular groove 153. Then, since the diameter of the inner wall of the annular groove 153 is less than a distance of the connecting portion between the first through hole 1141 and the second through hole 1142, the vibration pad 150 can be moved from the first through hole 1141 to the second through hole 1142. When the vibration pad 150 is positioned in the second through hole 1142, since the diameter of main body 151 of the vibration pad 150 is larger than the diameter of the second through hole 1142, the annular groove 153 can be effectively engaged in the second through hole 1142. After that, the hard disk drive securing screws 130 pass through the central hole 152 of the main body 151 and secures the hard disk drive 120 to the hard disk drive mounting frame 110. The vibration pad 150 further includes a plurality of first abutting portions 154 and a plurality second abutting portions 155. The first abutting portions 154 are formed at one end of the main body 151 to contact with the hard disk drive securing screw 130. The second abutting portions 155 are formed at the other end of the main body 151 to contact with the hard disk drive 120. In this embodiment, the first abutting portions 154 are arranged radially around the central hole 152 of the main body 151. Similarly, the second abutting portions 155 are also arranged radially around the central hole 152 of the main body 151.
In the electronic device 10 and the hard disk drive mounting frame 110 described above, a plurality of frame supporting holes 115 are formed at the bottom plate 111 to secure the hard disk drive mounting frame 110 to the printed circuit board. Since the frame supporting holes 115 are located directly under the hard disk drive 120 and covered by the hard disk drive 120, the size of the hard disk drive mounting frame 110 is decreased. In addition, the frame supporting holes 115 can also strengthen the air flow below the hard disk drive 120. Therefore, heat generated by the hard disk drive 120 can transmit through the frame supporting holes 115 to outer environment.
It is to be further understood that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
