In general, a notebook computer can receive signals from a wireless access point (AP) or a third-generation mobile communication via a built-in antenna, which is quite convenient for use. If an external antenna is used, it is not convenient to use the antenna to manually connect the antenna to the notebook. However, antennas that receive signals from third-generation mobile communication services often require a more southerly increase, while built-in antennas are lower in gain than external antennas. When the signal is weak, the signal received by the built-in antenna is easily interrupted, which affects the quality of the Internet.

FIG. 2 is a side view of the folding electronic device of FIG. Referring first to FIG. 1, the folding electronic device 1 includes a first body 110, a second body 120, a pivot mechanism 130, an antenna Μ0, and a transmission element U0. In the present embodiment, the first body (4) is, for example, a display of a notebook computer, and the second body 12 is, for example, a host of a notebook computer. The pivoting mechanism 13 is configured to pivotally connect the first body ΐι and the second body 120. 200910680 ^466twf.doc/p In detail, the pivoting mechanism 130 includes a turn # i32 and a bearing 134. The rotating shaft 132 is coupled to the first body n-bearing 134 body (10). The transfer is 132 and the axis * 134 is substantially bit = suitable for the second machine in the second line = : 2 ^ 2 I The first body 110 is relatively far from the side of the transfer (10). The end of the transmission 7G member 150 is connected to the carrier 134 and connected to the antenna 140. . It is also known that the first body 110 is opposite to the second body 120 and the shaft 132 produces a 1-rotational displacement with respect to the hemp 134. The rotational displacement causes the transmission element 15G to be linearly displaced toward the antenna. The first secret agent will cause the field 14 () to be privately shifted, and the antenna 140 is partially extended out of the first body. The stroke of the body is changed differently, that is, the rotation of the bearing 134 is equal to the m of the rotating shaft 132. In other words, the first body 110 in FIG. 2 is rotated relative to the second body member Γ2 with respect to the shaft (four), and the first machine=:::4° is retracted by the transmission element 150. A schematic diagram of the pivoting relationship of the pivoting machine of the above-mentioned folded electronic device. Referring to Figure 3, there is shown, for example, a connector 160' connector 160 that is snapped onto the spindle 132 and the transmission member 150 is secured to the bearing 134 by the connector 160. 200910680 --------..-466twf.doc/p In this example, the connecting member 160 is configured by a protrusion 162 and the vehicle, so that the connecting member (10) and the bearing 134, ^4 solid. When the ancient first body 11〇 is relative to the second body ί2, the special axis m can be moved relative to the connecting body brain to move the transmission body-four body. In addition, the transmission element (10) is fixed to the other protrusion 164. The rotation of the shaft 132 is the same angle = lower. The larger the diameter of the connector 16G is, the longer it is, the more the displacement of the transmission element 150 can be increased, and the distance over which the antenna 14 is extended is increased. FIG. 4 is a schematic diagram showing a connection relationship of the antenna disk of the folding electronic device of the above embodiment. Figure 5 is the (4) of the situation in Figure 4. Referring to FIG. 4 and FIG. 5, the antenna (10) can slide along the limit '184 in the body-body 11G, and is stopped by the limiting portion i84 on the moving path of the antenna H0 to define the moving path of the antenna 14〇. . The drive 150 can be located between the two limiting portions 182 to be arranged in parallel on the sliding path of the antenna 4〇. In addition to the manner in which the transmission element 15() is directly connected to the antenna 140, a displacement displacement (4) 17G' can be disposed between the transmission element 15A and the antenna 14A such that the antenna (10) (four) displacement is greater than the linear displacement of the transmission element 150. In order to increase the stretching distance and receiving effect of the antenna 14〇. In the present embodiment, the transmission element 15 is, for example, a spring piece, and when the driving element 15 is applied, the mineral-sized rack-and-pinion 172 can be formed directly on the transmission tree 15 (), and the first-gear 176 Sorry. When the antenna = is processed, the second wire rod 4' of the woven shape may be formed on the side of the antenna 14G to be sprayed with the second gear 178. The first gear 丨% and the second gear 200910680 t466twf.doc/p 178 are coaxially pivoted to the first body m, and can be rotated synchronously. In the present embodiment, the first gear 176 can be integrally formed with the second gear 178. Further, when the first body 11 is opened relative to the second body 12, the transmission element 15 of FIG. 4 is driven by the cabinet rotation mechanism 13〇 to be displaced toward the antenna direction D, so that the first The rack 172 drives the first gear Μ. The L first gear 178 rotates synchronously with the first gear 172 to drive the second rack 178 to be displaced. Since the second gear 178 has a larger radius than the first gear 176, the displacement of the second rack 172 can be greater than that of the first rack 178, so that the extension distance of the antenna 14〇 can be increased to enhance the signal receiving capability of the antenna 140. . For example, if the ratio of the diameter of the first gear π to the second gear 178 is 2:1, and the displacement of the transmission element 15〇 is increased, the extension distance of the antenna 14〇 can be enlarged to 1 〇 . In summary, the present invention has the following advantages due to the fact that the antenna can automatically extend out of the body by the pivoting mechanism, so that the antenna can be extended beyond the body, and can be improved. The gain of the antenna 'has a better reception effect. 2. When the body is turned on or when the body is turned on, the antenna can be automatically extended or incomeed into the body, so that the operator can manually operate the antenna, so it is quite convenient to use. First, the displacement of the antenna can be increased by the displacement amplifying mechanism, so that the receiving effect of the antenna can be further enhanced. <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; And the retouching, 11 200910680 466 tw.
