DETAILED DESCRIPTION OF THE INVENTION
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.
Referring to FIG. 2, a clipping communication device 3 according to the preferred embodiment of the invention includes a first clipping arm unit 31, a second clipping arm unit 32, an antenna module 33 and a pivot unit 34.
The first clipping arm unit 31 has a first force exerting portion 311 and a first clipping portion 312, and the second clipping arm unit 32 has a second force exerting portion 321 and a second clipping portion 322. The first force exerting portion 311 is disposed corresponding to the second force exerting portion 321, and the first clipping portion 312 is disposed corresponding to the second clipping portion 322. In addition, the antenna module 33 is disposed in the first clipping arm unit 31, and the pivot unit 34 pivots on the first clipping arm unit 31 and the second clipping arm unit 32.
In this embodiment, the pivot unit 34 is disposed between the first force exerting portion 311 and the first clipping portion 312, and the pivot unit 34 is disposed between the second force exerting portion 321 and the second clipping portion 322. So, the user may exert forces to the first force exerting portion 311 and the second force exerting portion 321 to drive the first force exerting portion 311 and the second force exerting portion 321 toward each other, thus parting the first clipping portion 312 from the second clipping portion 322. On the contrary, as shown in FIG. 3, if the user applies forces to the first force exerting portion 311 and the second force exerting portion 321 to part the first force exerting portion 311 from the second force exerting portion 321, the first force exerting portion 311 and the second force exerting portion 321 drive the first clipping portion 312 and the second clipping portion 322 toward each other.
In addition, as shown in FIG. 4, the clipping communication device 3 may cooperate with an object 4, which may be a casing, such as a casing of a display, a casing of a lamp holder, a computer casing or a window casing. Of course, the object 4 may also be a table frame, a lamp stand, a book shelf or a window frame. In this embodiment, the object 4 is the casing of a notebook computer. At this time, the user may part the first force exerting portion from the second force exerting portion. In this case, the first clipping portion 312 and the second clipping portion 322 approach each other to clip the object 4 so as to support the weight of the clipping communication device 3, to prevent the socket (not shown) from being stressed, and thus to lengthen the product lifetime. In addition, the user may also clip the clipping communication device 3 at a position with the better signal receiving quality to enhance the communication quality. Furthermore, the user may also choose to clip the clipping communication device 3 at a proper position according to his/her convenience and usage requirements.
Referring to FIG. 5, the clipping communication device 3 may further include an elastic unit 37, which houses the pivot unit 34 and has one end 371 connected to an inner side of the first clipping arm unit 31 and the other end 372 connected to an inner side of the second clipping arm unit 32. The elastic unit 37 may be a spring or an elastic sheet. In this embodiment, the elastic unit 37 is a spring.
As shown in FIGS. 3 and 5, the user may exert forces to the first force exerting portion 311 and the second force exerting portion 321 to drive the first force exerting portion 311 and the second force exerting portion 321 toward each other. At this time, the two ends 371 and 372 of the elastic unit 37 are pressed to store the elastic potential energy. When the user stops exerting the forces to the first force exerting portion 311 and the second force exerting portion 321, as shown in FIGS. 2 and 5, the elastic unit 37 releases the elastic potential energy and parts the first force exerting portion 311 from the second force exerting portion 321 through the two ends 371 and 372. Thus, the first clipping portion 312 and the second clipping portion 322 approach other to clip the object subsequently.
In addition, as shown in FIG. 5, the first clipping arm unit 31 further includes a first containing portion 313. The first containing portion 313 is a concave portion or a closed chamber. The antenna module 33 is disposed in the first containing portion 313. In this embodiment, if the first containing portion 313 is a concave portion, a side surface of the antenna module 33 is exposed from the concave portion and thus the antenna module 33 can be assembled or replaced conveniently. Alternatively, if the first containing portion 313 is a closed chamber, the antenna module 33 is covered by the first clipping arm unit 31. So, it is possible to prevent the antenna module 33 from being influenced by environmental factors, such as the dust or moisture.
Furthermore, referring to FIGS. 6 and 7, the clipping communication device 3 further includes a circuit board 35, which is electrically connected to the antenna module 33. The circuit board 35 may be flexibly disposed according to the actual condition. For example, as shown in FIG. 6, the circuit board 35 may be disposed in the first containing portion 313 of the first clipping arm unit 31. Alternatively, as shown in FIG. 7, the circuit board 35 may also be disposed in a second containing portion 323 of the second clipping arm unit 32.
Also, as shown in FIG. 7, the clipping communication device 3 further includes a transmission cable 36 and a connector 36′. The transmission cable 36 is electrically connected to the circuit board 35 and the connector 36′. The transmission cable 36 transmits the signal, which is received or transmitted by the antenna module 33, through the circuit board 35. The transmission cable 36 may have different designs, such as a RS232 transmission cable, a 1394 transmission cable or a USB transmission cable, according to the actual requirement. In this embodiment, the transmission cable 36 is the USB transmission cable, and the connector 36′ is the USB connector.
In addition, at least one portion of the transmission cable 36 may be retracted in the pivot unit 34 to facilitate the management of the transmission cable 36. Of course, as shown in FIG. 8, the clipping communication device 3 may further include a retracting unit 38 for retracting at least one portion of the transmission cable 36. In this embodiment, the retracting unit 38 includes a reel 381 and a vortex spring 382. The reel 381 pivots on the pivot unit 34 and has a vortex groove 3811 for accommodating the vortex spring 382. The transmission cable 36 surrounds the outer edge of the reel 381. The vortex spring 382 has sufficient resilience to rotate the reel 381, so the transmission cable 36 can be easily retracted on the reel 381, or the transmission cable 36 retracted on the reel 381 may be pulled out for use. For example, the user can pull out the transmission cable 36 retracted on the reel 381, connect the connector 36′ to a socket (not shown) of the notebook computer, and then clip the clipping communication device 3 on the casing (not shown) of the notebook computer to support the weight of the clipping communication device 3, to prevent the socket of the notebook computer from being stressed, and thus to lengthen the product lifetime. In addition, the user may also clip the clipping communication device 3 at a position with the good signal reception so as to enhance the communication quality. Furthermore, the user may also dispose the clipping communication device 3 at a proper position according to his/her convenience.
In summary, the clipping communication device of the invention has the first clipping portion and the second clipping portion, so the user can bring the first clipping portion to the second clipping portion together in order to clip the object, to support the weight of the clipping communication device, and thus to prevent the socket from being stressed and lengthen the product lifetime. In addition, the user may also clip the clipping communication device at position with the good signal reception so as to enhance the communication quality. Furthermore, the user may also dispose the clipping communication device at the proper position according to his/her convenience.
