## Background
BACKGROUND
1. Technical Field
The disclosure relates to an electronic device and a releasing apparatus of the electronic device.
2. Description of Related Art
An electronic device, such as a server, may include a plurality of modules inserted in the housing of the electronic device. Each module often includes a hook to be locked to the housing. However, when the module needs to be pulled out from the housing, the space between the module and the housing may be too small to grasp and remove the module without great difficulty.

DETAILED DESCRIPTION
The disclosure, including the accompanying drawings, is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to FIG. 1 and FIG. 2, an exemplary embodiment of an electronic device includes a housing 10, an electronic module 20, a locking member 30, a bracket 40, and a releasing apparatus 50.
The housing 10 includes a side plate 14 and a receiving portion 12 bounded on one side by the side plate 14. A locking slot 142 is defined in the side plate 14.
In the disclosure, the electronic module 20 is a power supply unit received in the receiving portion 12 of the housing 10. A first end of the locking member 30 is fixed to an outer surface of the electronic module 20. The locking member 30 is a metal piece and includes a locking piece 32 adjacent to a second end of the locking member 30 opposite to the first end, to engage in the locking slot 142 of the housing, thereby fixing the module 20 in the receiving portion 12.
The bracket 40 is fixed to an outer surface of the side plate 14 of the housing 10. In the disclosure, the bracket 40 is a slide rail for slidably mounting the housing 10 to a cabinet (not shown in figures). The releasing apparatus 50 is fixed to the bracket 40 and faces the side plate 14 of the housing 10.
Referring to FIG. 3 and FIG. 4, the releasing apparatus 50 includes a mounting member 51, an operation member 53, a first connecting member 55, a second connecting member 57, and a resilient member 58.
The mounting member 51 is substantially a plate and defines a plurality of mounting holes 511 for mounting the mounting member 51 to the bracket 40. Three coaxial pivot portions 516 are formed at a first end of the mounting member 51. Two pairs of L-shaped locating portions 512 are formed on a second end of the mounting member 51. A tab 514 protrudes from a middle of the mounting member 51, between the pivot portions 516 and the locating portions 512.
The operation member 53 is slidably arranged between the locating portions 512 and the mounting member 51. A handle 536 is set at a first end of the operation member 53. Two coaxial pivot portions 534 are formed from a second end of the operation member 53. The operation member 53 longitudinally defines a slot 531 therein. A pin 532 extends from one sidewall bounding the slot 531 adjacent to the handle 536.
In the disclosure, the resilient member 58 is a helical spring. The resilient member 58 is received in the slot 531 of the operation member 53, with a first end of the resilient member 58 fitting about the tab 514 of the mounting member 51. A second end of the resilient member 58 resists against the tab 514 of the mounting member 51 away from the handle 536.
Two spaced pivot portions 551 are formed from a first end of the first connecting member 55. The first end of the first connecting member 55 is pivotably connected to the first end of the mounting member 51 through a shaft 60 extending through pivot portions 551 and the pivot portion 516 adjacent to the first distal end of the mounting member 51. A pivot portion 553 is formed from a middle of a second end of the first connecting member 55. The second connecting member 57 is similar as the first connecting member 55 in structure. The second connecting member 57 includes two pivot portions 571 at a first end and a pivot portion 573 at a second end. The first end of the second connecting member 57 is pivotably connected to the second end of the first connecting member 55 through a shaft 70 extending through the pivot portion 553 of the first connecting member 55 and the pivot portions 571 of the second connecting member 57. The second end of the second connecting member 57 is pivotably connected to the second end of the operation member 53 through a shaft 80 extending through the pivot portions 534 of the operation member 53 and the pivot portion 573 of the second connecting member 57. The pivot portion 553 of the first connecting member 55 and the pivot portions 571 together form an engaging part 59.
Referring to FIG. 5, to release the electronic module 20 from the housing 10, the handle 536 is operated to deform the resilient member 58 and slide the operation member 53 inward relative to the mounting member 51, thereby driving the first connecting member 55 and the second connecting member 57 to rotate to raise the engaging part 59 away from the mounting member 51. The engaging part 59 resists against the locking member 30 to deform the locking member 30 toward the electronic module 20, until the locking piece 32 is released from the locking slot 142. The electronic module 20 can be pulled out from the housing 10.
In an alternative embodiment, the releasing apparatus 50 may be directly fixed to the outer surface of the side plate 14 of the housing 10.
In the disclosure, the electronic device includes a releasing apparatus 50 attached to the housing 10 to release the electronic module 20 from the housing, which is convenient to use.
It is to be understood, however, that even though numerous characteristics and advantages of certain 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.
