The shield part 126 has a mounting tab 1260 formed on a top edge thereof and approximated to the inner shaft 27. The second end 282 of the torsion spring is fixed in the mounting tab 1260.
Please refer to FIG. 2B. The holding portion 22 has a stopping member 23 formed a top edge thereof, and faced to the first end edge 111 of the base plate 11. The stopping member 23 is disposed in the switch recess 20 and against an inner edge of the covering plate 12. As shown in FIG. 2B, the holding portion 22 further includes an anti-sliding portion 222 formed on the bottom edge of the holding portion 22 and opposite to the stopping member 23. In this embodiment, the stopping member 23 is extended to two sides and against an edge of the pair of pivoting boards 124. The covering plate 12 of this embodiment is inwardly protruded with a flange 123 along a top edge of the switch recess 120 corresponding to the stopping member 23. The stopping member 23 is arranged against the flange 123, so that the top edge of the switch module 2 is blocked by the edge of the switch recess 120.
The stopping member 23 of this embodiment has a pushing block 232 protruded inward and approximated to the retaining portion 111. The pushing block 232 and the hooking end 244 are located at two sides of the retaining portion 111 respectively. When the hooking end 244 is moved away from the retaining portion 111, the pushing block 232 is against the retaining portion 111. According to this embodiment, when the hooking end 244 left the retaining portion 111 of the base plate 11, that means it is in unlocking condition, a force exerted by user on the switch module 2 will directly act on the hook piece 24 through the pushing block 232 of the stopping member 23, and the covering plate 12 will leave immediately the retaining portion 111 of the base plate 11. In other words, this embodiment has advantages of direct-operation and effort-saving, when opening the covering plate 12.
Please refer to FIGS. 3A to 3F, which show cross-sectional views of different actions during opening the covering plate 12. The retaining portion 111 is substantially L-shaped in a cross-sectional view, including a vertical portion extended downward from a side edge of the base plate 11, and a horizontal portion inwardly extended toward the housing. A distance between the pushing block 232 and the hooking end 244 is larger than the length of the horizontal portion of the retaining portion 111, as shown in FIG. 3A.
Please refer to FIG. 3A, which shows the switch module 2 in a locking position. The rotating axis X, which is located on a center of axle portion 25, is substantially arranged under the retaining portion 111. In this position, the top end of the holding portion 22, which is formed with the stopping member 23, is extended to an outer side of the retaining portion 111. The pushing block 232 faces the retaining portion 111. Besides, the hooking end 244 of the hook piece 24 is hooked to an inner side of the retaining portion 111.
Please refer to FIG. 3B, which shows the holding portion 22 which is pulled outward by user to open the switch module 2. The hook piece 24 is rotated in clockwise direction along the rotating axis X, so that the hooking end 244 can leave the retaining portion 111. In the meantime, the pushing block 232 on the top end of the holding portion 22 exerts an action force on the retaining portion 111 of the base plate 11. According to law of action and reaction, the retaining portion 111 of the base plate 11 therefore exerts a reaction force on the holding portion 22, which is on the covering plate 12. Thus, the covering plate 12 simultaneously moves outward away from the base plate 11. In other words, the opening action by user pulling the holding portion 22 also makes the covering plate 12 to move outward. Comparing some traditional computer housing, user not only needs to turn a switch, but also needs to exert force to pull the covering plate outward away from the housing. The opening action of prior art is not direct and not simple.
Please refer to FIG. 3C, which shows the covering plate 12 left outward the base plate 11 with a predetermined distance. In this condition, the elastic element 28 is twisted and stores elasticity because of the rotation of the holding portion 22. The hooking end 244 of the hook piece 24 slides over a bottom side of the retaining portion 111.
Please refer to FIG. 3D, which shows the holding portion 22 of the switch module 2 rotating into the switch recess 120 in counterclockwise direction along the rotating axis X. The holding portion 22 shown in this condition can be deemed as being released by user. In this condition, the plug portions 1222 of the covering plate 12 is still wedged in the inserting holes 1520 of the bottom plate 15, so that the covering plate 12 can be pushed outward about its bottom end as the fulcrum. Through the recovering elasticity from the elastic element 28, the oblique surface 242 of the hook piece 24 contacts and exerts an action force on a bottom of the retaining portion 111. The retaining portion 111 provides a reaction force on the hook piece 24, which is also on the covering plate 12. Even user did not exert force, and the covering plate 12 can be continuously pushed outward so as to disengage the covering plate 12 from the base plate 11 effortlessly, as shown in FIG. 3E, until the holding portion 22 of the switch module 2 completely coming into the switch recess 120. The present disclosure therefore provides an effortless operation for user.
Please refer to FIG. 3F, showing the switch module 2 completely away from the base plate 11. In this condition, the covering plate 12 is slanted and a little distance from the base plate 11a, so that user can conveniently take the covering plate 12 outward. In the meantime, even the user did not exert force on the covering plate 12, the covering plate 12 is still able to be pushed outward by gravity and more far away the base plate 11. The user can take the covering plate 12 outward more conveniently.
Refer to FIGS. 4A to 4F, which are different conditions about the covering plate 12 being pushed until closed the covering plate 12 on the base plate 11.
Please refer to FIG. 4A. When user wants to close the covering plate 12 to the base plate 11, the second end edge 122 of the covering plate 12 is firstly inserted into an outer edge of the bottom plate 15 (see FIG. 2), so the covering plate 12 can be rotated about the second end edge 122. Then, the user only needs to push the covering plate 12 toward the base plate 11.
Please refer to FIG. 4B. The oblique surface 242 of the hook piece 24 is pushed to against the retaining portion 111 and slide on the retaining portion 111 so as to correspondingly rotate the hook piece 24 about the rotating axis X. Until the hooking end 244 of the hook piece 24 contacts and exerts an action force to a bottom of the retaining portion 111, the retaining portion 111 will produce a reaction force to the hook piece 24. In the same time, the hook piece 24 is rotating clockwise about the rotating axis X, as shown in FIG. 4C. During the process of closing the covering plate 12, the user is not required to pull the holding portion 22, just push the covering plate 12. The hook piece 24 will continuously rotate until the condition as shown in FIG. 4D, and the hooking end 244 of the hook piece 24 contacts the bottom of the retaining portion 111. In the meantime, the elastic element 28 is stretched by the rotation of the holding portion 22 and has elastic potential energy.
As shown in FIG. 4E, when the covering plate 12 is continuously pushed toward the base plate 11, the hooking end 244 of the hook piece 24 slides over the bottom of the retaining portion 111, and enters into the retaining portion 111.
As shown in FIG. 4F, by the elastic potential energy provided form the elastic element 28, the holding portion 22 can rotate counterclockwise about the rotating axis X and come back into the switch recess 120. The hooking end 244 of the hook piece 24 moves upward to engage with the retaining portion 111. Therefore, the covering plate 12 is locked with the base plate 11 by the switch module 2.
When the holding portion 22 is moved outside, the hook piece 24 shifts accordingly and the hooking end 244 is disengaged with the retaining portion 111 to dismount the covering plate 12. When the covering plate 12 is pushed toward the base plate 11 and the hooking end 244 is against the retaining portion 111, the hook piece 24 is rotated correspondingly and engaged with the retaining portion 111 for closing the covering plate 12 to the base plate 11.
In conclusion, the present disclosure provides the housing having quick-dismounting structure, when the holding portion 22 is opening by user, the covering plate 12 is pushed outward in the same time. Therefore, the housing with quick-dismounting structure of the present disclosure can be directly and simply open or close the covering plate 12. Further, the elastic potential energy from the elastic element 28 not only helps the holding portion 22 back to the original position, but also provides action and reaction forces between the switch module 2 and the retaining portion 111. Thus, the present disclosure can open or close the covering plate 12 effortlessly.
