DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1, a hidden image capturing device applied to a display, wherein the image capturing module of the hidden image capturing device is in an activation status. On the other hand, in FIG. 2, it shows the image capturing module in a stored status. The hidden image capturing device 20 disclosed herein is used in a display 10, particularly to that of a laptop computer. However, it is also applicable to an independent display (not shown) of a desktop computer.
As shown in FIG. 3 and FIG. 4, a three-dimensional exploded view and a three-dimensional assembled view of the hidden image capturing device are shown respectively. The display 10 includes at least a first shell 21, a control module 22, a slide module 23, and an image capturing module 24.
The first shell 21 is the outer case of the display 10, with at least a first panel 211 and a second panel 212. In addition, the first panel 211 is provided with a buckle member 213. When the display 10 is placed on a desk, the first panel 211 refers to the panel surface on top of the first shell 21. On the other hand the second panel 212 refers to the panel surface on the bottom of the first shell 21. Generally speaking, the first panel 211 and second panels 212 are integrally formed, in a roughly perpendicular configuration. The buckle member 213 is a push-type buckle with a buckle opening. Besides, shafts 215 are disposed at the positions corresponding to that of each slide groove 234 of the second panel 212.
The control module 22 has a fix board 221, at least one stand 222, and at least one contractible member 223.
The fix board 221 is a flat board, and it is fixed on the second panel 212 by the shafts 215 and kept a distance away from the second panel 212. The shaft 215 is an object with specific width and height. Its width just fits the slide groove 234, so that the slide module 23 can slide in the slide groove 234 smoothly, and its height has to let the fix board 221 keeps a distance away from the first shell 21. The distance is used to provide a space for the slide module 23 moving.
The stands 222 are fixed on the fix board 221 and it is a rectangular hollow bar. A guide rod 224 is disposed on the inner side of each stand 222. The guide rod 224 is suspended in the stand 222 to let the contractible member 223 install in the guide rod 224. Moreover, the axial orientation of each stand 222 is parallel to the sliding direction of the slide module 23.
Each of the contractible members 223, such as a spring, is slipped on the guide rod 224 respectively. It has a first end 225 and a second end 226. Also, the first end 225 is in touch with the inner side of a stand bottom 227. When the image capturing element 242 is not in use, the slide module 23 slides toward the lower side of the display 10. Therefore, the contractible member 223 is compressed. On the other hand, when the image capturing element 242 is in use, the slide module 23 slides toward the upper side of the display 10. Therefore, the image capturing element 242 can be extended out by the contractible member 223.
The slide module 23 comprises a slide board 231, at least one clamp member 232, and a combining member 233.
The slide board 231 is a flat board and disposed between the second panel 212 and the fix board 221. Sliding grooves 234 are respectively formed at the places corresponding to each shaft 215 on the slide board 231. Each shaft 215 is disposed inside the slide groove 234 and in touch with the two inner sides of the slide groove 234 by its outer edge in a movable way. The combination of the slide grooves 234 and the shafts 215 enables the slide board 231 to slide within a fixed range of the opening of the slide grooves 234. When the top end of the opening of the slide groove 234 of the slide board 231 is in touch with the shaft 215, the image capturing module 24 reaches its stored position. On the other hand, when the lower end of the opening of the slide groove 234 of the slide board 231 is in touch with the shaft 215, the image capturing module 24 reaches its activation position. The size of the opening of the slide groove 234 is the range that the image capturing module 24 reaches its activation position when being use and aligns with the surface of the first panel 211 when being stored.
Each of the clamp members 232 is disposed on the slide board 231 at a position corresponding to that of each second end 226 of the contractible member 223 respectively. The clamp member 232 has an opening, so that the guide rod 224 can be moved therein; therefore, when the image capturing element 242 is in a stored status, the slide board 231 moves toward the lower side of the display 10, and the clamp member 232 moves with the slide board 231 in the same direction. Besides, the second ends 226 of the contractible members 223 are respectively disposed at the clamp members 232. Therefore, as the clamp member 232 moves with the slide board 231 in the same direction, the contractible member 223 is compressed to an energy-storing state.
The combining member 233 is fixed on the slide board 231 at a position corresponding to that of the buckle member 213. The combining member 233 and the buckle member 213 can be easily connected together or separated. The combining member 233 is a rod. Since it is disposed on the slide board 231, it moves with the slide board 231 in the same axial direction. The end of the combining member 233 is provided with a combining buckle, so that the combining buckle can be inserted into the opening of the buckle member 213 to buckle up. Therefore, when the image capturing element 242 is not in use, the slide board slides toward the lower side of the display 10 and thereby gets fixed. The energy-storing state of the contractible member 223 is thus maintained.
Once a user wants to use the image capturing element 242, the user can push the shell of the image capturing module 24. The force of the push is transferred by the image capturing module 24 to the slide board 231, and then to the combining member 233. Since the buckle member 213 is a push-push connector, the combining member 233 and the buckle member 213 will depart from each other when a force is imposed thereon, and the contractible member 223 in the energy-storing state extends. The slide board 231 is pushed toward the upper side of the display 10, so as to let the image capturing module 24 out of the first panel 211.
The image capturing module 24 is disposed on the slide board 231. It has a second shell 241 provided with an image capturing element 242. The image capturing module 24 is mainly composed of an image capturing element 242 and a conventional control circuit coupled to the image capturing element 242. The image capturing element 242 may be a charge-coupled device (CCD) or a complementary metal-oxide semiconductor (CMOS) device.
Please refer to FIGS. 5A and 5B, the other embodiment of a hidden image capturing device when it is stored and how an actuating plate turns off a switch are shown. When the user is not using the image capturing element 242, for reasons of saving power and showing the status of the image capturing element 242 on a user interface, an actuating plate 235 is provided on one side end of the slide board 231 of the slide module 23. The actuating plate 235 slides with the slide board 231 in the same axial direction, so that a switch 214 (e.g. a micro switch) can be disposed on the second panel 212 beside the moving line of the actuating plate 235. Therefore, when the image capturing element 242 is not in use, the slide board 231 slides toward the lower side of the display 10, driving the actuating plate 235 to turn off the switch 214.
On the other hand, please refer to FIGS. 6A and 6B, a hidden image capturing device when it is activated and how an actuating plate in FIG. 6A turns on a switch are shown. If the image capturing element 242 is in use, the slide board 231 slides toward the upper side of the display 10, driving the actuating plate 235 to turn on the switch 214. Since the switch 214 is electrically coupled to and controlling the control circuit (not shown) of the image capturing module 24, the on or off of the switch 214 serves as a means for the control circuit to activate or store the image capturing element 242, so that the user can see the status of the status of the hidden image capturing device through the user interface.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
