Each mounting bracket 30 comprises a mounting plate 31 mounted to the corresponding side wall 23, and a receiving shell 33 coupled to the mounting plate 31. Each receiving shell 33 can be positioned beyond the front end of the corresponding side wall 23, such that the receiving shells 33 can face each other. The receiving shells 33 and the front wall 25 cooperatively bound an installing space 35. Each receiving shell 33 comprises a coupling plate 331 substantially perpendicular to the front wall 25, two side plates 332 extending substantially perpendicularly from the coupling plate 331, a top plate 333 coupled between top portions of the side plates 332, and a bottom plate 335 coupled between bottom portions of the side plates 332.

The coupling pole 3314 is located between the through hole 3313 and the guiding slot 3312. A distal end of the coupling pole 3314 axially defines a fastening hole 3315. A lower portion of each side plate 332 defines a mounting hole 3322. A block 3325 located adjacent to the corresponding mounting hole 3322 protrudes from one of the side plates 332 into the receiving slot 336.
Each latching apparatus 50 comprises a latching member 52, a first resilient member 53, a fastening member 54, an operating member 56, a shaft 57, and a second resilient member 58.

An adjusting plate 525 extends substantially perpendicularly from the circumference of the rotating portion 522, such that the adjusting plate 525 is substantially perpendicular to the extending pole 523. A latching pole 526 extends substantially perpendicularly from a distal end portion of the extending pole 523. The rotating portion 522 axially defines a shaft hole 527.

Referring to FIG. 3, the panel 70 comprises a front surface 711, a rear surface 712 opposite to the front surface 711, a bottom surface 713 coupled between bottom sides of the front surface 711 and the rear surface 712, and two opposite end surfaces 714. A latching bar 72 and a positioning bar 75 protrude from each end surface 714. Each latching bar 72 is adjacent to the rear surface 712, and each positioning bar 75 is adjacent to the front surface 711. Each latching bar 72 and the corresponding positioning bar 75 cooperatively bound a sliding slot 76. Each latching bar 72 comprises a positioning portion 721 mounted to an upper portion of the corresponding end surface 714, and a guiding portion 723 slantingly extending from a bottom end of the positioning portion 721 toward the rear surface 712. Each positioning bar 75 comprises a coupling portion 752 substantially parallel to the positioning portion 721, and a substantially triangular latching portion 753 extending toward the front surface 711 from an upper end of the coupling portion 752. The latching portion 753 forms a slanted guiding surface 755, and an abutting surface 756 is formed between the guiding surface 755 and the coupling portion 752.
In assembly, the main body 532 of each first resilient member 53 is fitted about the corresponding coupling pole 3314. Each latching member 52 is received in the receiving slot 336 of the corresponding receiving shell 33, such that the latching pole 526 extends through the corresponding guiding slot 3312, and the shaft hole 527 of the rotating portion 522 aligns with the fastening hole 3315 of the coupling pole 3314. Each fastening member 54 extends through the shaft hole 527 of the corresponding latching member 52 and engages in the fastening hole 3315 of the corresponding coupling pole 3314. Thus, each latching member 52 is rotatably coupled to the corresponding coupling pole 3314, and each latching member 52 can rotate to move the corresponding latching pole 526 along the corresponding guiding slot 3312. The first abutting pole 533 of each first resilient member 53 abuts against the corresponding block 3325, and the second abutting pole 535 resiliently abuts against the corresponding extending pole 523, to drive the corresponding extending pole 523 to rotate the corresponding latching pole 526 toward the chassis 20 until the latching pole 526 is stopped by an end of the corresponding guiding slot 3312.
The main body 582 of each second resilient member 58 is received in the cutout 568 of the corresponding operating member 56 such that the first abutting pole 583 abuts against an inner surface of the corresponding operating plate 563, the second abutting pole 585 abuts against the corresponding block 3325, and the through hole 568 of the main body 582 is aligned with the rotating hole 567. Each operating member 56 is received in the receiving slot 336 of the corresponding receiving shell 33 such that the resisting plate 562 extends through the through hole 3313, the abutting piece 565 abuts against a bottom portion of the corresponding adjusting plate 525, and the rotating hole 567 aligns with the mounting holes 3322 of the corresponding receiving shell 33. Each shaft 57 extends through the mounting hole 3322 of one of the side plate 332 of the corresponding receiving shell 33, the rotating hole 567, and the corresponding second resilient member 58, and engages in the mounting hole 3322 of the other side plate 332 of the receiving shell 33.
FIGS. 4-6 illustrate a process of assembling the panel 70 to the chassis 20. The bottom surface 713 of the panel 70 is first inserted into the installing space 35 from above the chassis 20. The guiding portions 723 slidably abut against the corresponding latching poles 526 to slide the latching poles 526 along the corresponding guiding slots 3312 away from the front wall 25 of the chassis 20 until the latching poles 526 are received in the corresponding sliding slots 76. Thus, the latching members 52 are rotated forward, and the first resilient members 53 are deformed. The panel 70 is pressed down, causing the latching poles 526 to slide further along the sliding slots 76, until each latching pole 526 exits out of a top end of the corresponding sliding slot 76. The first resilient members 53 are restored to bias the latching members 52 to rotate back, causing each latching pole 526 to engage with a top portion of the corresponding positioning portion 721. Thus, the bottom surface 713 of the panel 70 is located above the resisting plates 562 of the operating members 56, and the panel 70 is assembled between the receiving shells 33.
FIGS. 7-8 illustrate a process of disassembling the panel 70 from the chassis 20. The operating plates 563 are rotated away from the corresponding receiving shells 33 about the corresponding shafts 57, thereby causing the abutting pieces 565 of the operating members 56 to slidably abut against the adjusting plates 525 of the latching members 52. Thus, the latching members 52 are rotated toward the front surface 711 of the panel 70, thereby causing each latching pole 526 to disengage from the corresponding positioning portion 721 and slidably abut against the corresponding guiding surface 755. In this position, the resisting plates 562 abut against the bottom surface 713 of the panel 70, and the first resilient members 53 and the second resilient members 58 are deformed. The operating members 56 are further rotated away from the corresponding receiving shells 33, thereby causing the resisting plates 562 to lift up the panel 70. Thus, the latching poles 526 are slid along the corresponding guiding surfaces 755, thereby further deforming the first resilient members 53 and the second resilient members 58 until the latching poles 526 align with the corresponding abutting surfaces 756. The first resilient members 53 are partially restored to bias the latching members 52 to rotate back, until the latching poles 526 are latched to the corresponding abutting surfaces 756. Thus, the panel 70 is supported on the latching poles 526 of the latching members 52. The operating members 56 are released, the panel 70 can be detached from the receiving shells 33, and the first resilient members 53 and the second resilient members 54 are restored to rotate the operating members 56 toward the corresponding receiving shells 33 about the shafts 57, and rotate back the latching members 52.
Even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the present disclosure is illustrative only, and changes may be made in detail, including in the matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
