## Background
BACKGROUND OF THE INVENTION
1. Field of Invention
The invention relates to a fixing structure and an electronic apparatus and, in particular, to a screw-free fixing structure for an electronic assembly.
2. Related Art
In the age of information explosion, a hard disk drive may be the most important secondary storage device in a computer system. A hard disk drive provides a storage space that is cheap, fast and large capacity, and can store operating system, application programs, and user data.
Traditionally, a detachable hard disk drive is fixed in a frame in advance. This frame may be a part of the housing of a computer system. As shown in FIG. 1, a traditional detachable hard disk drive 11 is provided in a frame 12. The lateral sides of the frame 12 has a plurality of screw holes 121, which corresponds to the fixing holes 111 on the lateral sides of the hard disk drive 11, so that the frame 12 and the hard disk drive 11 can be assembled by screws 13.
However, one needs many screws 13 to assemble the hard disk drive 11 mentioned above. This raises the assembly time required, slows down the production speed, and adds additional costs to purchase the screws, which raises the production costs. Furthermore, the thread of the screws tends to be damaged when excess forces are applied to the screws. This results in the replacement of the screws, which wastes resources and further raises the production costs.
Moreover, when replacing, maintaining or expanding the hard disk drive 11, professional tools such as screwdrivers are required. Since the size of a screwdriver is not big, it is easy for one to lose the screwdriver, which results in the idle of the assembly jobs.
It is therefore an important subject to provide a fixing structure for a detachable electronic assembly and an electronic apparatus, which can solve the above-mentioned problems.
SUMMARY OF THE INVENTION
In view of the above, the invention is to provide a screw-free fixing structure to fix a detachable electronic assembly, and an electronic apparatus having such a fixing structure.
To achieve the above, a fixing structure for fixing a detachable electronic assembly according to the invention includes a housing, a first movable member and a second movable member. The detachable electronic assembly has at least one first hole. The housing has at least one guiding bar, at least one first connecting portion, and a first opening corresponding to the first hole. The first movable member has a second opening and a second connecting portion, wherein the first movable member is pivotally connected with the housing, and the second connecting portion is locked with the first connecting portion. The second movable member has a third opening and a protrusion, wherein a part of the second movable member passes through the second opening, and the guiding bar passes through the third opening, the second movable member moves along the guide bar by the rotation of the first movable member so that the protrusion is inserted into the first opening and the first hole.
The apparatus having the fixing structure according to the invention has a detachable electronic assembly, a housing, a first movable member, and a second movable member. The detachable electronic assembly has at least one first hole. The housing has at least one guiding bar, at least one first connecting portion, and a first opening corresponding to the first hole. The first movable member has a second opening and a second connecting portion, wherein the first movable member is pivotally connected with the housing, and the second connecting portion is locked with the first connecting portion. The second movable member has a third opening and a protrusion, wherein a part of the second movable member passes through the second opening, and the guiding bar passes through the third opening, the second movable member moves along the guide bar by the rotation of the first movable member so that the protrusion is inserted into the first opening and the first hole.
As mentioned above, the fixing structure of the invention moves the second movable member by rotating the first movable member. When the first movable member rotates, the protrusion on the second movable member fixes the electronic assembly to the housing or releases the electronic assembly from the housing. Since no screw is needed, the assembly time and material costs are both reduced. Furthermore, since the second connecting portion on the first movable member is used to connect with the first connecting portion on the housing, the fixing and releasing operation of the user is easier and more convenient. Furthermore, the first movable member and the second movable member are connected directly or indirectly, or are limited to move on the housing, therefore the user does not have to worry about not being able to fix detachable electronic assembly due to part missing.

As shown in FIG. 5 and FIG. 7, to release the detachable electronic assembly 31, the first movable member 22 is rotated to move the second connecting portion 222 away from the housing 21. The guiding portion 228 pushes the second movable member 23, and makes the second movable member 23 to move away from housing 21. The detachable electronic assembly 31 is released from the housing 21 after the protrusion 232 is pulled out from the first hole 311.
To sum up, according to the embodiments of the invention, the fixing structure moves the second movable member by rotating the first movable member. When the first movable member rotates, the protrusion on the second movable member fixes the electronic assembly to the housing or releases the electronic assembly from the housing. Since no screw is needed, the assembly time and material costs are both reduced. Furthermore, since the second connecting portion on the first movable member is used to connect with the first connecting portion on the housing, the fix and release operation of the user is easier and more convenient. Furthermore, the first movable member and the second movable member are connected directly or indirectly, or are limited to move on the housing, therefore the user does not have to worry about not being able to fix detachable electronic assembly due to part missing.
