2. Related Art
Laptop computers have the advantages of being light and compact. For the sake of mobility, some of them have fewer peripheral input/output (I/O) ports in order to reduce the number of elements and the size. For non-mobile applications, the laptop computer can be connected to an I/O port extending base for complete peripheral I/O functions.
Generally speaking, the I/O port extending base has specific sizes for specific models of laptop computers. For example, the extending base for a 14-inch laptop computer usually cannot connect with a 15-inch laptop computer. In that case, the manufacturers have to make extending bases for each size laptop computer. This inevitably increases the product cost.
Moreover, various types of I/O ports (e.g., RS-232, RJ-45, PS2, VGA, USB, etc) on the usual extending base are directly exposed. Although it is easier for the user to plug in or unplug cables, the overall appearance of the laptop computer suffers due to the exposed I/O ports. Moreover, dust is likely to accumulate thereon. If these I/O ports are hidden inside a case, the appearance is improved. However, the space of such a case is limited and it is more difficult for the user to plug in or unplug cables.
Therefore, it is an important subject to provide a case of an extending base for an electronic device that can solve the above mentioned problems.
In view of the foregoing, the invention is to provide a case of an extending base for an electronic device that can be easily opened.
To achieve the above, the invention discloses a case of an extending base including a body, a cover, and at least two link elements. The body has a hollow, and the cover is disposed aside the hollow. Each link element has a first pivot part, a first block part, a second pivot part, and a first elastic member. The first pivot part has a first end pivoted on the body and a second end connected to the first block part. The second pivot part has a first end pivoted on the cover and a second end connected to the first block part. The first elastic member provides a force to push the first block part from a first position to a second position so as to correspondingly push the cover. Herein, when the first block part is positioned at the first position, the first block part is separated from the body and the cover covers the body. In addition, when the first block part is positioned at the second position, the first block part is in contact with the body and the cover is separated from the body.
As mentioned above, the case of an extending base for an electronic device according to the invention has the link elements to help to open its cover. The hollow of the body can be exposed once the cover is opened. Thus, it is convenient for the user to plug/remove cables into/from the I/O ports of the case.
The invention will become more fully understood from the detailed description given herein below illustration only, and thus is not limitative of the present invention, and wherein:
The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.
When the first block part 130 is positioned at the first position, the first block part 130 is separated from the body 11 and the cover 12 covers the body 11. When the first block part 130 is pushed by the first elastic member 133 and then positioned at the second position, the first block part 130 is in contact with the body 11 and the cover 12 is separated from the body 11.
In this embodiment, the cover 12 and the first block part 130 of the link element 13 are respectively installed on two opposite surfaces of the body 11. The cover 12 is disposed on the outer surface of the body 11 and partially covers the hollow 111. The first block part 130 of the link element 13 is disposed on the inner surface of the body 11. To connect the link element 13 and the cover 12, the second pivot part 132 of the link element 13 goes through the through hole 114 and extends toward the hollow 111. In addition, the second pivot part 132 of the link element 13 pivots about the cover 12.
The first end of the first pivot part 131 pivots on the base 112 of the body 11. In more detailed, the base 112 has small holes 113, and the first pivot part 131 has protruding parts 134. The first end of the first pivot part 131 of the link element 13 can be pressed inward before it is put into the base 112. Accordingly, the protruding parts 134 of the link element 13 can be inserted into the small holes 113 on the base 112. Therefore, the link element 13 can rotate about the axis of the first end of the first pivot part 131, which is also the center of the small holes 113. In this case, the axis is parallel to the body 11.
The first elastic member 133 is a torsion spring disposed by the base 112. Its one end is connected to the first block part 130, and its other end is disposed on the body 11 or connected to the body 11. When the cover 12 covers the body 11, the first block part 130 is positioned at the first position (the first block part 130 is separated from the body 11). In this case, the first elastic member 133 is depressed and produces an elastic restoring force. To open the cover 12 with respect to the body 11, the link element 13 rotates along a first direction D1 so that the first block part 130 touches the body 11. Additionally, the second pivot part 132 pushes the cover 12 away from the hollow 111. The elastic restoring force helps rotate the link element 13 along the first direction D1. Therefore, the cover 12 can be readily opened, exposing the hollow 111. It this thus convenient for the user to plug/remove a cable into/from the I/O port in the hollow 111 of the body 1.
Moreover, the user can exert a force on the cover 12, so that it moves toward the body 11. In this case, the link element 13 rotates along a second direction D2, while the first block part 130 departs from the body 11 until the cover 12 covers the body 11.
Since the elastic restoring force of the first elastic member 133 tends to push the cover 12 away from the body 11, the cover 12 has a plurality of hooks 120 in order to fix the cover 12 to the body 11. The hooks 120 can catch the body 11, so that the cover 12 can be fixed to the body 11.
Moreover, the first end of the second pivot part 132 is pivoted on a base 121 of the cover 12. The base 121 has small holes 122, and the second pivot part 132 has protruding parts 135. The first end of the second pivot part 132 of the link element 13 can be pressed inward before it is put into the base 121. Accordingly, the protruding parts 135 of the link element 13 can be inserted into the small holes 122 on the base 121. Therefore, the link element 13 can rotate about the axis of the first end of the second pivot part 132, which is also the center of the small holes 122. In this case, the axis is parallel to the cover 12.
After the cover 12 is departed from the hollow 111, it can rotate about the first end of the second pivot part 132 to expose the whole hollow 111. This makes it convenient for the user to use elements disposed inside the hollow 111 of the body 11.
Moreover,
When the second block part 140 is positioned at the first position, the second block part 140 is separated from the body 11 and the cover 12 covers the body 11. When the second block part 140 is positioned at the second position, the second block part 140 is in contact with the body 11 and the cover 12 is separated from the body 11.
The first end of the third pivot part 141 is pivoted on a base 115 of the body 11. In the embodiment, the third pivot part 141 has protruding parts 144. The third pivot part 141 can be pressed inward before it is put into the base 115. The protruding parts 144 can be inserted into the small holes 116 on the base 115. Therefore, the auxiliary positioning element 14 can rotate about the axis of the first end of the first pivot part 141, which is also the center of the small holes 116. The rotational axis is parallel to the body 11.
The auxiliary positioning element 14 is disposed on the inner surface of the body 11. In order for the auxiliary positioning element 14 and the cover 12 to be combined together, the fourth pivot part 142 of the auxiliary positioning element 14 goes through a through hole 117 of the body 11 and extends toward the hollow 111. In addition, the fourth pivot part 142 of the auxiliary positioning element 14 pivots on the cover 12.
The first end of the fourth pivot part 142 is pivoted on a base 123 of the cover 12. The base 123 has small holes 124, and the fourth pivot part 142 has protruding parts 145. The second end on the fourth pivot part 142 of the auxiliary positioning element 14 can be pressed inward before it is put into the base 123. The protruding parts 145 of the auxiliary positioning element 14 can be inserted into the small holes 124 on the base 123. Therefore, the auxiliary positioning element 14 can rotate about the axis of the second end of the fourth pivot part 142, which is also the center of the small holes 124. The rotational axis is parallel to the cover 12.
The second elastic member 143 is an extension spring, with its both ends connecting to the base 115 and the second block part 140. The second elastic member 143 has a larger elastic restoring force than the first elastic member 133. The restoring forces of the two elastic members are in opposite directions.
When the second block part 140 is positioned at the first position, the second block part 140 is separated from the body 11 and the cover 12 covers the body 11. The second elastic member 143 pulls the second block part 140 so that the cover 12 stably covers the body 11.
When the second block part 140 is positioned at the second position, the second block part 140 is in contact with the body 11 and the cover 12 is separated from the body 11. The elastic restoring force of the second elastic member 143 has a zero or almost zero component along the second direction D2. Therefore, the second elastic member 143 does not pull the second block part 140 to rotate along the second direction D2.
Furthermore, to cover the body 11 with the cover 12, the second elastic member 143 with a larger elastic restoring force helps pull the second block part 140 to rotate along the second direction D2 and to move the cover 12 toward the hollow 111. Therefore, the second block part 140 departs from the body 11, and the cover 12 covers the body 11.
In this embodiment, the case 1 is the case of the extending base of an electronic device (e.g., a laptop computer). The hollow 111 of the body 11 accommodates the RS-232, RJ-45, PS2, VGA, and USB I/O ports. The user can plug/remove cables into/from the I/O ports.
In summary, the case of an extending base for an electronic device according to the invention has the link elements to help to open its cover. The hollow of the body can be exposed once the cover is opened. Thus, it is convenient for the user to plug/remove cables into/from the I/O ports of the case.
Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense. Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to persons skilled in the art. It is, therefore, contemplated that the appended claims will cover all modifications that fall within the true scope of the invention.
