Detailed ways

FIG. 1 is a perspective view of an external hard disk according to an embodiment of the present invention. FIG. 2 is an exploded view of the external hard disk in FIG. 1 . Please refer to FIG. 1 and FIG. 2 at the same time. The external hard disk 100 of this embodiment includes a hard disk main body 110 , a plurality of soft elastic parts 120 and a casing 130 . The hard disk main body 110 has a plurality of assembly holes 112 , and the soft elastic members 120 are respectively disposed in the assembly holes 112 . Each soft elastic member 120 has an opening 122 , and the casing 130 has a plurality of protrusions 132 , wherein positions of the protrusions 132 correspond to positions of the assembly holes 112 of the hard disk main body 110 . The protrusions 132 are respectively inserted into the openings 122 to fix the casing 130 and the hard disk main body 110 to each other.

It should be noted that the housing 130 of this embodiment is composed of an upper housing 130a and a lower housing 130b. When assembling, first put the hard disk main body 110 into the lower case 130b, and insert the two protrusions 132 on the lower case 130b into the corresponding two openings 122 respectively. Then, cover the lower case 130b with the upper case 130a so that the hard disk main body 110 is covered by the upper case 130a and the lower case 130b together, and simultaneously pass the two protrusions 132 of the upper case 130a through the two protrusions of the lower case 130b respectively. The two corresponding openings 122 are respectively inserted through the holes H.

When the external hard disk 100 of this embodiment is impacted by an external force or vibrated by other factors, the vibration energy will be transmitted to each soft elastic member 120 through the shell 130, and the soft elastic member 120 can absorb at least part of the vibration energy to avoid It is passed to the hard disk main body 110 . In other words, compared with the prior art that fixes the casing to the hard disk body in a locking manner, and arranges elastic gaskets between the casing and the hard disk body to achieve a shock-absorbing effect, the present embodiment inserts the protrusion 132 of the casing 130 The soft elastic member 120 in the assembly hole 112 of the hard disk main body 110 is assembled in a tightly fitting manner. The soft elastic member 120 used to achieve the shock absorbing effect is located in the assembly hole 112, so it does not occupy the space between the casing 130 and the hard disk main body 110, so that the external hard disk 100 can be compared with the existing external hard disk. Has a smaller volume.

In addition, since the present embodiment uses the elastic deformation of the soft elastic member 120 to fix the housing 130 to the hard disk main body 110 in a tightly fitting manner, it is not necessary to assemble the housing 130 in a locked manner through screws and screw holes. Save assembly time and cost. In this embodiment, the material of the soft elastic member 120 may be rubber, and the material of the shell 130 may be metal (for example, the material of the shell 130 is aluminum). However, the present invention does not limit the materials of the soft elastic member 120 and the shell 130 , which can be other suitable materials that can achieve the same effect.

Please refer to FIG. 1 and FIG. 2 at the same time. In this embodiment, the external hard disk 100 further includes a circuit board 140 . The circuit board 140 is fixed on the hard disk main body 110 and is electrically connected with the hard disk main body 110 , and is covered by the casing 130 together with the hard disk main body 110 . Besides, the circuit board 140 has a transmission plug 142 and a universal serial bus (Universal Serial Bus, USB) plug 144. The circuit board 140 is electrically connected to the hard disk main body 110 through the transmission plug 142 . The housing 130 has an opening 134 to expose the USB plug 144 through the opening 134 . Therefore, the USB plug 144 can be electrically connected with an external USB connector (not shown) for data transmission with other electronic devices (such as notebook computers or desktop computers).
