DETAILED DESCRIPTION OF THE INVENTION
The following description is one of the embodiments of the invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims.
FIG. 2 is a schematic bottom view showing a disassembling device of the present invention, FIGS. 3A and 3B show partially enlarged views of the disassembling device in FIG. 2. A disassembling device 100 of the present invention can be applied to a portable computer, and the disassembling device 100 includes a housing 110, a battery module 120, and a rotating element 130, wherein the battery module 120 is disposed in the housing 110 in a detachable manner, so that a user can detach the battery module 120 from the housing 110 by merely rotating the rotating element 130 (as shown in FIGS. 3A and 3B). In this embodiment, the rotating element 130 is a baffle pad, so that when the disassembling device 100 is placed on a plane, the baffle pad prevents a surface of the disassembling device 100 from being damaged. In other words, the disassembling device 100 utilizes the baffle pad, i.e. rotating element 130, as a detaching button, wherein a surface of the baffle pad is aligned with the housing 110 to hide the detaching button, which overcomes the unappealing structural issue found in the art.
FIGS. 4A and 4B show partially schematic views of an inner structure of the disassembling device of the present invention, wherein the rotating element 130 includes a rod 131, a rotating body 132, a pin 133, and a first flexible part S1. The rod 131 is rotatably disposed in the housing 110, and the rotating body 132 is connected to the rod 131 and exposed outside of the housing 110. After rotating the rotating body 132, the rod 131 is triggered to rotate and enabling the pin 133, connected to the rod 131, to be rotated between a first position P1 (as shown in FIG. 4A) and a second position P2 (as shown in FIG. 4B). Additionally, the first flexible part S1 is disposed on the rod 131, and when the rod 131 is rotated to the second position P2 from the first position P1, the first flexible part S1 is compressed, resulting a restoring force actuating the rod 131 to reversely rotate to the first position P1 from the second position P2.
The housing 110 includes a first engaging portion 140. The first engaging portion 140 includes a body 141, a catch interlocker 142, a first positioning portion 143 and a flexible arm 144. The body 141 of the first engaging portion 140 is abutted against the pin 133 of the rotating element 130, and the catch interlocker 142 is formed on the body 141. When the pin 133 is rotated to the second position P2 from the first position P1, the first engaging portion 140 is pushed, enabling the first positioning portion 143 to be connected to the body 141 by the flexible arm 144.
Referring to FIG. 5, FIGS. 4A and 4B. FIG. 5 shows a schematic view of the disassembling device of the present invention in a state when the first engaging portion 140 is engaged with a second engaging portion 150. The battery module 120 includes a second engaging portion 150. The second engaging portion 150 includes a hook 151, a second positioning portion 152, and a slant side 153. Wherein the battery module 120 is engaged with the housing 110 by an engagement between the first engaging portion 140 and the second engaging portion 150, as shown in FIG. 4A. Specifically, it is the hook 151 of the second engaging portion 150 interlocking the catch interlock 142 of the first engaging portion 140 that enables the battery module 120 to be fixed in the housing 110. Referring to FIG. 4B, when the pin 133 is rotated to the second position P2 from the first position P1, the first engaging portion 140 is pushed by the pin 133, resulting a movement of the first engaging portion 140, which pushes the second engaging portion 150 along the slant side 153, making the hook 151 detach from the catch interlock 142, while at the same time, the second engaging portion 150 is pushed away from the first engaging portion 140, making the battery module 120 detach from the housing 110. Also, after the hook 151 is detached from the catch interlock 142, due to an interlocking fit between the first positioning portion 143 and the second positioning portion 152, an engagement occurs therebetween, and the battery module 120 and the housing 110 are kept in a predetermined position, which prohibits the second engaging portion 150 from going back to a state of being engaged with the first engaging portion 140. Thus, a user can easily withdraw the battery module 120 from the housing 110.
It should be noted that, as shown in FIG. 5, a hollowing out structural design is applied between the body 141 and the flexible arm 144. When the slant side 153 of the second engaging portion 150 is abutted against the first positioning portion 143, by utilizing the restoring force of the flexible arm 144, a user can push the second engaging portion 150 with minimal force.
Additionally, the disassembling device 100 further includes a second flexible part S2, disposed in the housing 110 and abutted against the housing 110 and the body 141 of the first engaging portion 140, respectively. When the first engaging portion 140 is pushed by the rotating element 130, the second flexible part S2 is compressed by the first engaging portion 140 and provides a restoring force to the body 141, which enables the body 141 to be reversely moved to an original position.
While the invention has been described by way of example and in terms of embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
