The ports 13 and 23 of the first storage device 1 and the second storage device 2 are all interfaces such as SATA specifications.

In this embodiment, the protective cover 3 is made of a soft material and is shock absorbing, and includes a substrate 31, a set of body units 32, and two pad thickness units 33. . In this embodiment, the soft material of the protective cover 3 can be silicone rubber, rubber, or Thermoplastic Polyurethane (TPU) or other materials, and the first storage device 1 or the second storage can be absorbed due to material properties. The vibration energy generated by the operation of the device 2 can be used to mitigate the shock caused by falling or being subjected to external force, and has the effect of earthquake resistance. Moreover, the friction between the protective cover 3 made of a soft material and the surface of a contact surface (not shown) provides the protective cover 3 with anti-slip effect.

The substrate 31 has a frame-shaped frame portion 310, and the frame portion 310 defines a substrate opening 311. In this embodiment, the top view of the substrate opening 311 is rectangular, but not limited thereto, and may be a triangle, a pentagon, a hexagon or the like. The substrate 31 further has a first surface 312, a second surface 313 opposite to the first surface 312, two long sides 314 respectively located on opposite sides of the frame portion 310, and two opposite ends of the two connecting long sides 314. Side 315, and four inner edges 316 surrounding substrate opening 311.

The sleeve unit 32 is connected to the substrate 31 and protrudes from the first surface 312 to define an accommodating space 34. The sleeve unit 32 has a sleeve opening 322 that communicates with the accommodating space 34, and a housing unit 32. A barrier 323 spaced from the first surface 312 of the substrate 31. In the present embodiment, the sleeve unit 32 has two sleeves 321 which are spaced apart from each other and are respectively connected to the substrate 31. The two sleeves 321 are respectively connected to opposite sides of the substrate 31, that is, the two short sides 315 of the substrate 31. And extending to a portion of the adjacent two long sides 314 and protruding from the first surface 312. And the two sets of bodies 321 are jointly defined Out of the sleeve opening 322, the sleeve opening 322 is provided for the first storage device 1 or the second storage device 2. Since the connecting ports 13 and 23 of the first storage device 1 and the second storage device 2 are disposed on one of the short sides 12 and 22, the sleeve body 321 forms a retaining groove on the side corresponding to the connecting ports 13 and 23. 324, in order to facilitate the insertion of the first storage device 1 or the second storage device 2, the connection port 13 forms a good electrical connection with the external connector (not shown), and can cover the first storage device 1 or the second Four corners of the storage device 2. Although the two sleeves 321 of the present embodiment are exemplified by the four corners of the first storage device 1 or the second storage device 2, the two sleeves 321 may be disposed only at two opposite corners of the substrate 31.

The angle between the first surfaces 312 is greater than or equal to 180 degrees, and even the two body portions 331 may flatten the second surface 313 of the substrate 31 (not shown). Preferably, the two body portions 331 are horizontally disposed with the frame portion 310 of the substrate 31 in the initial position. At this time, the substrate 31, the second sleeve unit 32 and the two body portions 331 collectively define the accommodating space 34. The first storage device 1 is housed, and the distance between the inner surface of the barrier wall 323 of each sleeve 321 and the first surface 312 of the substrate 31 is defined as a first distance D1. That is, when the sheet portion 331 of the two pad thickness unit 33 is in the initial position, the first storage device 1 can be mounted in the protective cover 3. Referring to FIG. 1, FIG. 2, FIG. 7, and FIG. 8, if the second storage device 2 is to be mounted in the protective cover 3, the first portion of the frame portion 310 stacked on the substrate 31 in the direction of the arrow I is reversed. The surface 312 positions the two body portions 331 at the overlapping position, and defines that the distance between the blocking wall 323 and the body portion 331 is a second distance D2, and the second distance D2 is smaller than the first distance D1, so that the accommodating space 34 is vertical. The distance in the direction of the substrate 31 can be adjusted to accommodate the second storage device 2. Moreover, the two body portions 331 can be reversed back to the initial position in the direction of the arrow II. Thereby, the user can select the first storage device 1 to position the two body portions 331 in the initial position or select the second storage device 2 to position the two body portions 331 in the overlapping position.

It is to be noted that since the two pad thickness units 33 are connected to the substrate 31 symmetrically, the heights of the opposite sides of the substrate 31 can be evenly thickened when the two body portions 331 are in the overlapping position. The storage device 2 can be smoothly placed in the accommodating space 34, which is more beneficial to the improvement of the seismic effect.

Therefore, the size of the accommodating space of the protective cover 3 can be adjusted by the two-piece body 331 in an initial position or a folded position, so as to facilitate the installation of the first storage device 1 or the second storage device 2 having different thicknesses.
