## Background
BACKGROUND
1. Technical Field
The present disclosure relates to protective apparatuses and, more particularly, to a shockproof apparatus for an electronic device.
2. Description of the Related Art
To transport electronic devices, such as computers, foam or other shock-absorbing materials are often used in the packing boxes holding the electronic devices. However, for electronic devices subject to frequent relocatings, packing and unpacking the electronic devices time after time is tedious and time-consuming. Moreover, the packing material is generally fragile and has a short life span, therefore, frequent replacement of the packing material is inevitable, which brings extra cost.

DETAILED DESCRIPTION
Referring to FIG. 1, an embodiment of a protective apparatus is provided to protect an electronic device 100, such as a computer. The protective device includes a packing box 10, a base 20, a first band 30, and two second bands 40.
The packing box 10 includes a rectangular main body 11 defining an opening 112 for the computer 100 entering the main body 11, and a cover 13 to cover the opening 112. Two substantially U-shaped railways 14 are respectively attached to inner surfaces of opposite sidewalls 114 of the main body 11, adjacent to a bottom of the main body 11.
Referring to FIG. 2, the base 20 includes a first supporting bracket 21, a second supporting bracket 23, four abutting members 25, two first resilient members 27, and four second resilient members 29. The first supporting bracket 21 includes a rectangular bottom plate 211, and two sidewalls 213 perpendicularly extending up from opposite sides of the bottom plate 211, respectively. Two first bulges 2113 protrude up from the bottom plate 211, adjacent to opposite ends of the bottom plate 211, respectively. Two first positioning pins 2115 extend up from the bottom plate 211, at diagonally opposite corners of the bottom plate 211. Two second positioning pins 2117 extend from each corner of the bottom plate 211. Each of the first positioning pins 2115 and the second positioning pins 2117 defines a threaded hole (not labeled) along an axis. Two protrusions 2131 extend from a top of each of the sidewalls 213, adjacent to opposite ends of the sidewall 213. Two wheels 2133 are attached to an outer surface of each of the sidewalls 213.
The second supporting bracket 23 includes a bottom plate 231 and two end walls 233 perpendicularly extending up from opposite ends of the bottom plate 231, respectively. A transverse depressed portion 2311 is defined in the bottom plate 211, with two locking tabs 2312 extending up from a bottom of the depressed portion 2311. Each of the locking tabs 2312 defines a rectangular attachment notch 2314. Two second bulges 2316 protrude down from the bottom plate 231, adjacent to the two end walls 233, respectively. Two first positioning holes 2318 are defined in the bottom plate 231, at diagonally opposite corners of the bottom plate 231, respectively. Two second positioning holes 2319 are defined in each corner of the bottom plate 231.
Each of the abutting members 25 is substantially L-shaped, and includes an abutting portion 252 and a fixing portion 254 perpendicularly extending from a bottom end of the abutting portion 252. Each abutting portion 252 members 25 defines a rectangular engagement notch 2521, adjacent to a top end of the abutting portion 252 opposite to the fixing portion 254. A mounting post 2522 perpendicularly extends from each abutting portion 252, parallel to and above the fixing portion 254. Each fixing portion 254 defines two lengthwise fixing holes 2541, with a lengthwise direction of each of the fixing holes 2541 perpendicular to the abutting portion 252.
In one embodiment, the first resilient members 27 and the second resilient members 29 are coil springs.
Opposite ends of the first band 30 can be tied up via a latch member 32.
Two hooks 42 are respectively attached to opposite ends of each of the second bands 40.
Referring to FIGS. 2 and 3, in assembly of the base 20, the first resilient members 27 are placed around the corresponding first bulges 2113 of the first supporting bracket 21. The second supporting bracket 23 are received in the first supporting bracket 21, with the second bulges 2316 aligning with the corresponding first bulges 2113 of the first supporting bracket 21 and extending into the first resilient members 27. The first positioning pins 2115 of the first supporting bracket 21 correspondingly extend through the first positioning holes 2318 of the second supporting bracket 23, and the second positioning pins 2117 of the first supporting bracket 21 correspondingly extend through the second positioning holes 2319 of the second supporting bracket 23. Two screws 801 are respectively engaged in the threaded hole of the first positioning pins 2115, to retain the second supporting bracket 23 to the first supporting bracket 21. The first resilient members 27 are kept between the bottom plate 211 of the first supporting bracket 21 and the bottom plate 231 of the second supporting bracket 23, to absorb shock of the bottom plate 231.
Each abutting member 25 is mounted to the second supporting bracket 23, with two corresponding second positioning pins 2117 at one of the corners of the second supporting bracket 23 extending through the fixing holes 2541 of the abutting member 25. Two screws 803 are engaged in the threaded holes of the second positioning pins 2117 to secure the abutting member 25 to the bottom plate 231 of the second supporting bracket 23.
The abutting portion 252 of each of the abutting members 25 is generally perpendicular to the bottom plate 231 of the second supporting bracket 23, and the mounting posts 2522 of the abutting members 25 perpendicularly extending towards the protrusions 2131 of the sidewalls 213 of the first supporting bracket 21, respectively. The second resilient members 29 are placed around the corresponding mounting posts 2522 of the abutting members 25. Opposite ends of each of the second resilient members 29 resist against the abutting portion 252 of a corresponding one of the abutting member 25 and the corresponding protrusion 2131 of the first supporting bracket 21. Therefore, the second resilient members 29 may absorb shock to the abutting members 25.
Referring to FIGS. 1 and 4, in packing the computer 100, the computer 100 is placed on the bottom plate 231 of the second supporting bracket 23, with the end walls 233 of the second supporting bracket 23 respectively abutting against a front wall 101 and a rear wall 102 of the computer 100, and the abutting portions 252 abutting against opposite sidewalls 104 of the computer 100. The lengthwise fixing holes 2541 enable adjustments of distances between the abutting portions 252 of corresponding abutting members 25 to accommodate other computers with different thickness. Opposite ends of the first band 30 is tied with the latch member 32 after the first band 30 is wound around the computer 100 and extends through the attachment notches 2314 of the locking tabs 2312. Each of the second bands 40 is wound around the computer 100, and opposite ends of the second band 40 are respectively engaged in the engagement notches 2521 of two opposite abutting members 25. Therefore, the computer 100 is prevented from tilting.
The base 20 together with the computer 100 is slid into the main body 11, with the wheels 2133 of the first supporting bracket 21 slidably received in the railways 14 of the main body 11 of the packing box 10, respectively. The cover 13 is attached to the main body 11 of the packing box 10, to cover the opening 112 of the main body 11, and the computer 100 is prepared for transportation. During transportation, the first resilient members 27 and the second resilient members 29 can absorb shocks, therefore, shockproof protection is provided for the computer 100.
In some applications of moving the computer 100 for a short distance with the computer 100 kept in operation, the computer 100 can merely be received in the base 20 and transported, and the packing box 10, the first band 30, and the second bands 40 omitted.
It is believed that the present embodiments and their 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 description or sacrificing all of its material advantages, the examples hereinbefore described merely being exemplary embodiments.
