Description of the Invention: [Technical Field] The present invention relates to a dual antenna module, and more particularly to an expandable antenna module. [Prior Art] In the prior art, a personal computer is used to watch a television by externally connecting a television box to a computer system, or inserting a television card into a computer system and receiving a wired or wireless television signal. Use your computer as a TV to watch cable or wireless TV programs. For applications where a computer is used to watch a television program, the antenna device of the built-in or external television card of the notebook computer can be used to receive the wireless television signal for viewing the television program. The existing antenna device is equipped with a double-open antenna, and the antenna can be separately opened by manual. Since the double-opening antennas of the antenna device are symmetrically deployed with each other, the receiving quality is better, and therefore, the user must manually and adjust the antenna to be symmetrically spread. Φ It can be seen that the double-opening antenna of the above antenna device cannot be automatically and symmetrically unfolded and cannot be repeatedly deployed to the same angle. Therefore, the above-mentioned antenna device still has inconvenience and defects, and needs to be further improved. Therefore, how to effectively eliminate the above inconveniences and defects is one of the current important research and development topics, and it has become an urgent need for improvement in related fields. SUMMARY OF THE INVENTION The present invention discloses a dual antenna module that can be automatically deployed to the outside, and is provided with a dual-opening dual antenna module that can be automatically opened in 201230486, so as to increase the user's willingness to use. The present invention discloses a dual antenna module that can be automatically deployed to provide a dual open antenna module that can be symmetrically opened for better reception quality. The invention discloses a dual antenna module which can be automatically deployed to provide an opening angle of an appropriate frequency. In one embodiment of the present invention, the double antenna module that can be automatically deployed to the outside comprises a housing, two gears, two antennas, a first elastic component, a release portion, and a limiting portion. The two gears are pivotally disposed within the housing and are intermeshing with each other, wherein one of the gears has at least one stop projection. The two antennas are located on opposite sides of the housing and are respectively secured to the gears such that they rotate out of the housing synchronously with the rotation of the gears. The two ends of the first elastic element are respectively connected to the housing and one of the gears. The release portion is located on the surface of the housing. One end of the limiting portion is connected to the release portion, and the other end is abutted against the stopper projection. Thus, when the first elastic member is deformed, the limiting portion abuts against the stopper projection, and the rotation of the first elastic member and the rotation of the gear can be prevented, thereby controlling the two antennas to be temporarily located in the casing. Conversely, when the limiting portion is away from the stopper projection, the first elastic member that returns to rotate the gear, the two antennas can be synchronously driven to rotate out of opposite sides of the housing. In one embodiment of this embodiment, the dual antenna module that can be automatically deployed to the outside further includes a second elastic component. The second elastic member is located in the housing, and the two ends of the second elastic member are respectively connected to the release portion and the housing. In one embodiment of this embodiment, the gear with the stop projection includes a gear body of 201230486. The gear body has a front surface, a circumferential surface and a plurality of gear teeth, the circumferential surface surrounding the front surface, the teeth are spaced apart from the circumferential surface, wherein the stop projection protrudes from the front surface and adjacent to the circumference The position of the face is used to be abutted by the limit portion. In another embodiment of this embodiment, the gear having the stop projection includes a gear body having a front face, a circumferential face and a plurality of gear teeth. The circumferential bread is surrounded by the front faces, and the teeth are arranged at intervals on the circumferential surface. A plurality of stop bumps are arranged at intervals on the front side and adjacent to the circumferential surface for being sequentially abutted by the limiting portion. In this embodiment, the stop bumps each have an abutment surface for contacting the limit portion. The height of these abutment surfaces is gradually increased in accordance with the order of the contact limit portions. In addition, each of the stop projections has a return slope. The return slope abuts the abutment surface for lifting the limit portion. In still another embodiment of this embodiment, the teeth have the same size, and the antennas are all turned out of the housing at the same angle. The antennas are turned out of the housing at an angle of 90 degrees, 105, 120, 135, 150, 165 or 180 degrees, respectively. In still another embodiment of this embodiment, each antenna includes an antenna post, a connecting portion, and a pivot. One end of the connecting portion is fixed to the corresponding gear. The pivot pivots the antenna column and the other end of the connecting portion. In another embodiment of the present invention, a dual antenna module that can be automatically deployed to the outside is provided. The dual antenna module comprises a housing, two gears and two antennas. The two gears are of the same size and are respectively pivoted on one side of the housing and are coupled to each other. The two antennas are located on opposite sides of the housing, and the gears are fixed one by one. The antennas are all turned out of the housing at the same angle. In summary, the dual antenna module 201230486 which can be automatically deployed by the present invention can be symmetrically deployed, automatically deployed, and multi-segmented antenna design, and the user only needs to release the limit of the first gear by one hand. A gear and a second gear automatically, symmetrically and synchronously drive the deployment of the first antenna and the second antenna to quickly achieve better reception quality, thereby increasing the user's willingness to use. BRIEF DESCRIPTION OF THE DRAWINGS The spirit of the present invention will be apparent from the following description of the embodiments of the present invention. It does not depart from the spirit and scope of the invention. Since the double-opening antenna of the conventional antenna device cannot be automatically abducted, the present invention provides a dual antenna module that can be automatically deployed to the outside, and provides an antenna design that is more convenient and more quickly provided by an automatically abducted driving design. In order to quickly achieve better reception quality, thereby increasing the user's willingness to use. Please refer to Figure 1 and Figure 2. FIG. 1 is a schematic diagram showing the appearance of a dual antenna module 100 that can be self-expanded according to an embodiment of the present invention. FIG. 2 is a schematic view showing the dual antenna module 100 viewed from the first cover 210 in the direction D1 of FIG. 1 . FIG. 3A is a schematic view showing the dual-antenna module 100 viewed through the second cover in the direction D2 of FIG. 1 . The dual antenna module 100 can be automatically deployed to include a housing 200, a first gear 310, a second gear 320, a first antenna 410, a second antenna 420, and a first elastic component 500. A release portion 600 and a limiting portion 700. 201230486 The housing 200 includes an upper cover 21〇 and a lower cover 220. The upper cover 210 and the lower cover 220 are covered with each other to form an internal space 23〇, and the first gear 310, the first gear 320, and the first antenna 41 are respectively arranged. The second antenna 420, the first elastic element 500, and the limiting portion 7 are disposed in the internal space 23A. The first gear 310 and the second gear 32 are respectively pivoted inside the casing 2 and are engaged with each other so as to be mutually rotatable and synchronously rotated. The first antenna 410 is located on one side of the housing 200 and is fixed to the first gear 31〇, and synchronously rotates out of the thin side of the housing as the first gear 310 rotates. The second antenna 420 is located on the other side of the housing 200 and is fixed to the second gear (10), and synchronously rotates out of the other side of the housing 2 with the rotation of the second gear 320. The lower cover 220 has a first receiving slot and a second receiving slot 222. The first receiving slot 221 and the second receiving slot are configured to receive the first antenna 410 and the second antenna 42. In other words, the first blade and the second antenna 420 can be housed in the casing 2b. The antenna 41 is connected to both ends of the first housing 200 by the two ends of the first elastic member 500. The non-moving member generally refers to a component such as the first member 10 and the stationary member when rotating, for example, the convex member 2^the wheel 31 of the inner wall of the housing is shown in the drawing, so that the first elastic member has the second restoring force. . In this embodiment, the first elastic member 5 is "", and a contraction spring is generated. However, the present invention is not limited thereto, and the first elastic-spin-like extension type may also be a tension-like tension spring, a c-type elastic piece, an element 5's organ buckling piece, or the like. The organ buckling piece is considered to be composed of multiple? Type of shrapnel or shrapnel structure. The object is formed such that one end of the release portion 700 is exposed on the surface of the casing 2, and the mountain 200 is connected to the stopper portion 700. The upper cover 21 cooker is also connected to the hub body, and the internal space of the opening of the opening of the 201230486 230 is 211. The releasing portion 600 is movably disposed in the opening 211 (Fig. 3A), and is connected to the limiting portion 700 through the opening 211. A second elastic member 620 is further included between the release portion 600 and the housing 200. The second elastic member 620 is located in the housing 200 adjacent to the opening 211 and is sleeved on one of the fixing posts 610 of the release portion 600. Both ends of the second elastic member 620 are respectively connected to the releasing portion 600 and the stationary member inside the casing 200. The movable member generally refers to a stationary member when the displacement portion 600 is displaced, for example, an inner wall of the housing (as shown in FIG. 3A), so that the second elastic member 620 can release the displaced portion 600 and the limiting portion 700. Bring back to the original position. In this way, the release portion 600 can be realized as a button (as shown in FIG. 1) or a handle (not shown) according to different designs, thereby driving the limiting portion 700 to be synchronously displaced in the direction D1. In this embodiment, the second elastic member 620 is a spiral telescopic spring. However, the present invention is not limited thereto, and the second elastic member 620 may be of a type such as a spiral bracing spring, a C-shaped elastic piece, a U-shaped elastic piece or an organ buckling piece, or the like. The organ buckling piece is regarded as a shrapnel structure composed of a plurality of sheet-like objects. Please refer to Figures 3A and 3B. FIG. 3B is a first view. The second cover 220 and the limiting portion 700 are seen in the direction D2 to view the dual antenna module 100. In this embodiment, the second gear 320 has at least a first stop projection 330 (or only one stop projection). The first stop projection 330 protrudes from the surface of the second gear 320. One end of the limiting portion 700 away from the releasing portion 600 is located on a rotation stroke of the first stopping projection 330 as the second gear 320 rotates to limit the second gear 320 by resisting the first stopping projection 330 Rotation, at the same time, because the second gear 320 is coupled to the first gear 310, the 201230486 limit portion 700 also indirectly limits the rotation of the first gear 310. In other embodiments, the stop projections may also be located on the first gear 31〇' on the same gear as the first elastic member 500, or may limit the rotation of the second gear 320 by restricting the rotation of the first gear 310. . The first antenna 410 and the second antenna 420 are rotated in the clockwise directions R2 and R4 to accommodate the first antenna 410 and the second antenna 420 in the first receiving slot 221 and the second receiving slot 222, respectively. At the time (Fig. 2 and Fig. 3A), the first gear 310 deforms the first elastic member 500 due to the rotation, and the limiting portion 700 abuts against the first stop projection 330 of the second gear 320 (the third eight In order to prevent the rotation of the second gear 320 and the first gear 310, the return of the first elastic member 5 can also be restricted. On the contrary, refer to FIG. 4A, FIG. 4B and FIG. 5A. Fig. 4a is a schematic view showing the operation of the release portion of Fig. 1 after being pressed. The first potential /1 Λ Figure % is not shown in Figure 4. When the release part is pressed, the second cover is seen in the direction D2 to see the operation diagram of the dual antenna module. The fifth drawing shows that the two antennas of the dual antenna module that can be automatically unfolded are respectively unfolded at a 90 degree operation. 'After the release portion 600 is pressed, the release portion 600 can be displaced in the direction of the internal space 3 (such as the direction D1), thereby driving the limiting portion 700 away from the first stop projection 33 (Fig. 4A and 4B) ). Since the limiting portion 7 抵 abuts against the first stop projection 330 of the second gear 320 (Fig. 4B), the special limiting portion 7 〇〇 no longer blocks the movement of the second gear 320. At this time, the first elastic element 500 is rotated to drive the first gear 310 to rotate in the hour hand direction R1 (FIG. 5A). Then the first gear 31 〇 synchronously rotates the second gear 32 〇, so the first antenna 410 and the second antenna The antenna 420 is rotated in the hour hand direction R1 and the 201230486, respectively, and then the first 2 picture and the 5A picture are respectively turned out.

The first stop projection 330 and the first stop projection 350 respectively have an abutment surface 360 and a return slope 36 to return to the abutment surface 360. The gear body 340 has a front surface 341, a circumferential surface 342, and a plurality of gear teeth 343. The circumferential surface 342 surrounds the front surface 341 ′ and the teeth 343 are spaced apart from each other on the circumferential surface 342 . The first stop projections 330 and the second stop projections 350 protrude from the front surface 341 of the second gear 350 . Specifically, the stop projections (e.g., the first stop projection 330 and the second stop projection 350) are spaced apart from the front surface 341 of the gear body 340 and adjacent the circumferential surface 342. Thus, when the second gear 350 rotates in the hour hand direction R3, the abutment faces 360 of the stop protrusions (for example, the first stop protrusions 330 and the second stop protrusions 350) will be sequentially restricted. 7〇〇 abuts 'because the height of the abutment surface 360, that is, the top edge of the abutment surface 360 to the vertical length L of the front surface 341 of the gear body 340, will gradually increase in accordance with the order of contact with the limiting portion 700. To produce the effect of segmented rotation. When the release portion 600 is pressed for the first time, the stopper portion 700 moves with the release portion 6〇〇 without abutting against the first stopper projection 33〇 (FIG. 4A and FIG. 4B FIG. 201230486) because the second gear 320 does not The rotation of the first gear 31 is restricted, so that the restored first elastic member 500 can pull the first gear 310 to rotate the first gear 310 in the hour hand direction ri, thereby synchronously interlocking the second gear 320 to rotate accordingly. The first stop projection 330 passes through the limiting portion 7〇〇 (Fig. 4B) as the second gear 32 turns. However, since the abutment surface 360 of the second stop projection 350 has a higher height than the first The height of the abutment surface 360 of the stop projection 330 causes the limiting portion 7 to pass the first stop projection 330 again, and then abuts against the abutment surface 360 of the second stop projection 350 again. To limit the rotation of the first gear 31〇 and the second gear 320 again, and thus the angle of the first antenna 41〇 and the second antenna 42〇 may be limited to provide a multi-segment option for outreach (No. 5A). In this embodiment, refer to FIG. 5A. When the release unit 600 is pressed for the first time, The angles 0 1 and 02 of the antenna 41 〇 and the second antenna 42 对外 from the corresponding sides of the casing 2 对外 are 9 degrees, respectively. See FIGS. 5B and 6 . FIG. 5B Figure 5a is a schematic view showing the operation of the dual antenna module in the direction of the second cover when the release portion is pressed again. Figure 6 is a schematic view of the present invention, which can be automatically deployed to the outside world. Schematic diagram of operation at 135 degrees. When the release portion 6 is pressed a second time, the stopper portion 700 moves without releasing against the second stopper projection 350 (Figs. 4A and 5B) as the release 600 moves, due to the The two gears 320 no longer limit the rotation of the first gear 31, so that the first-elastic rotation of the recovery can pull the first wheel 3ig to rotate in the clockwise direction, and then synchronously rotate the second gear 32 to rotate accordingly. The stop projection 350 passes through the limiting portion 7〇〇 (Fig. 6) as the second gear 320 rotates, and further the first antenna and the second antenna object are further extended outward in 201230486 (Fig. 6 In this embodiment, the reference to Fig. 6 is repeated. When the release unit 600 is pressed for the second time, The angles β 1 and β 2 of the antenna 410 and the second antenna 420 from the corresponding sides of the housing 2 are respectively 135 degrees. Thus, when the second gear 320 includes more than two stop bumps, The dual antenna module 本 of the present invention can be designed with an antenna having a multi-segment abduction angle option. For example, the first antenna 410 and the second antenna 420 can be set at 15 degrees and set according to a desired angle. When the plurality of stop projections are on the front surface 341 of the gear body 340, the angles of the first antenna and the second antenna can be sequentially increased, for example, 90 degrees, 105 degrees, 120 degrees, 135 Degree, 150 degrees, 165 degrees and 180 degrees. However, the invention is not limited to this. Conversely, see Figures 5B and 7 for details. FIG. 7 is a schematic diagram showing the relationship between the limiting portion 700 of the dual antenna module 100 and the locking projections 330 and 350 of the dual antenna module 100 of the present invention. When the first antenna 410 and the second antenna 420 are rotated in the clockwise directions R2 and R4 to accommodate the first antenna 410 and the second antenna 420 in the first accommodating slot 221 and the second accommodating slot 222, respectively ( 2 and 3A), the first gear 310 and the second gear 320 are rotated in the hour hand directions R2 and R4, respectively (Fig. 5A and Fig. 3A). In particular, when the second gear 32 is rotated in the clockwise direction R4, each of the stop projections 330, 350 approaches the limiting portion 700, and the return inclined surface 361 contacts the inclined surface 701 of the limiting portion 7 (the seventh) Figure (丨)). Since the return slope 361 of each of the stop bumps 330, 350 and the slope 701 of the limiting portion 7 are matched with each other (FIG. 7 (ϋ)), the return slope 361 of each of the stop bumps 33, 350 can be The inclined surface 7〇1 of the contact contact portion 7〇〇 is moved along the inclined surface 701 to push up the limiting portion 7〇〇 (Fig. 7(ϋ)) until the first antenna 410 and the second antenna 420 are The receiving portion 700 is received in the first receiving groove 411 and the second receiving groove 412, and the limiting portion 700 abuts against the abutting surface 360 of any of the stop projections (Fig. 7(iii)). Referring to FIG. 2 , in the above embodiments, the first gear 310 and the second gear 320 are similarly disposed on the same surface of the lower cover 220 , and the first gear 310 and the second gear 320 have the same size. That is, the same number of teeth and pitch (ie, W1 is equal to W2), so that the first antenna 410 and the second antenna 420 can be synchronously and symmetrically transferred out of the casing 200, in other words, the first day. The angle θ 1 of the wire 410 out of the housing 200 can be the same as the angle 0 2 of the second antenna 420 out of the housing 200. Therefore, in view of the fact that the first antenna 410 and the second antenna 420 are symmetrically deployed with each other, the dual antenna module of the present invention can achieve better reception quality. However, it is to be understood that the present invention is also not limited to the fact that the first antenna 410 and the second antenna 420 cannot be rotated out of the housing 200 asymmetrically, in other words, when the first gear 410 and the second gear 420 do not have the same number of teeth. When the pitch (ie, W1 is not equal to W2), the angle θ 1 of the first antenna 410 to the housing is different from the angle Θ 2 of the second antenna 420 to the housing. In addition, as shown in FIG. 2, in an alternative embodiment of the present invention, each antenna 410, 420 includes an antenna post 43 and a connecting portion 432 and at least one pivot 433. One end of the connecting portion 432 is fixed to the corresponding gear 310 or 320, and the other end is pivotally connected to the antenna post 431 by a pivot 433. In this way, regardless of whether the first antenna 410 and the second antenna 420 are symmetrically outwardly developed at the same angle, the antenna pillars 431 of the first antenna 410 and the second antenna 420 can be respectively adjusted to be different. Angle to more flexibly reinforce the dual antenna module 100 of the present invention. 14 201230486 In addition, as shown in FIG. 2, in the embodiment, the first gear 31 〇 and the second gear 320 are respectively provided with an arcuate guide groove 370, and the arc of the curved guide sample 370 is equivalent to the first gear 310. The arcuate degree of the second gear 320 and the length of the arcuate guide groove 370 can be designed according to the maximum angle at which the antennas 41, 42 are outwardly deployed. The lower cover 220 has a blocking rod 224 corresponding to each of the arcuate guiding grooves 37, and the blocking rod 224 extends into the curved guiding groove 37〇, which can limit the maximum rotation angle of the 坌-gear 310 and the second gear 32〇, In order to ensure that the gear 3"0 and the second gear 32 are not excessively rotated, damage is caused: In summary, the antenna can be automatically extended to the symmetry, automatically expand, and multi-segmented antenna by the present invention. The release-release section automatically 'symmetrically and synchronously drives the gearwheel and the first deployment' for the limit gears of the first gear to quickly obtain a better reception, and the intention to use the two antennas. . </ RTI> </ RTI> </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> </ RTI> <RTIgt; The scope of protection is as follows [simplified description of the drawing] In order to make the above-mentioned invention of the present invention more: easy to understand 'the drawing: detailed: 22, advantages and real-actual external expansion % line - 2nd riding Figure 1 is a perspective view of the line module.
