[0017] Figure 2 It is a partial schematic diagram of the external electronic pen in the smart watch of the present utility model.

[0018] The descriptions of the reference numerals are as follows:

[0019] Built-in main board 10, external electronic pen 20, pen holder 21, pen cavity 22, table frame 30, feeding point 40, grounding point 50, first cable 60, second cable 61, first buckle 70, second buckle 71. DETAILED DESCRIPTION

[0020] The following is a further detailed description of the smartwatch proposed by the utility model in combination with the accompanying drawings and specific embodiments. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model. In addition, the structure shown in the accompanying drawings is often a part of the actual structure. In particular, the emphasis of each accompanying drawing is different, and sometimes different proportions are used.

[0021] Most of the existing smart watches use the wide body and the shell as the antenna or part of the antenna. As the functions of smart watches are increasing, the structure of the watch core is becoming more and more complicated, making the environment of the antenna inside the watch core more and more severe, and often causing interference problems that are difficult to solve during debugging. The utility model adds an external electronic pen 20 on the basis of the original smart watch, and uses the pen cavity 22 on the external electronic pen 20 on the smart watch as the antenna structure. On the one hand, the screen of the current smart watch is relatively small, and the existence of the external electronic pen 20 can better operate.

[0022] Specifically, the utility model provides a smart phone, which includes a watch strap and a dial, wherein the dial includes a built-in main board 10, an external electronic pen 20 and a watch frame 30 connected to the external electronic pen 20; the built-in main board 10 is electrically connected to the external electronic pen 20, the external electronic pen 20 includes a pen body 21 and a pen cavity 22, the pen body 21 is inserted and placed in the pen cavity 22, and the pen cavity 22 is configured with an external antenna; the pen cavity 22 is connected to the watch frame 30 through a connecting component, and a feeding point 40 and a grounding point 50 are provided on the pen cavity 22, and the built-in main board 10 leads out a cable to connect the feeding point 40 and the grounding point 50; the external antennas share a return point to increase the net space of the external antennas.

[0023] With such a configuration, the utility model can utilize the structural design of the external antenna to greatly improve the smart watch's antenna layout solution which is limited to the internal movement, and can also optimize the antenna layout solution, optimize the adverse effects of the antenna environment on the antenna, and reduce some of the effects of internal devices on the antenna.

[0024] Further, the connection component is configured as a first buckle 70 and a second buckle 71, the first buckle 70 is arranged at one end of the external electronic pen 20, and the second buckle 71 is arranged at the other end of the external electronic pen 20. The first buckle 70 and the second buckle 71 are both configured as annular buckles, one end of the external electronic pen 20 is connected and fixed by the first buckle 70, and the other end of the external electronic pen 20 is inserted into the buckle groove position of the watch frame 30.

[0025] Specifically, the pen cavity 22 of the external electronic pen 20 and the watch frame 30 of the smart watch are fixed by a double-headed plastic buckle, namely the first buckle 70 and the second buckle 71. One end of the external electronic pen 20 is fixed by a ring buckle connection, and the other end needs to be inserted into the buckle slot of the watch frame 30 of the smart watch. When installing, it is directly inserted, and the spring releases the tension to push the marble into the slot for fixing. When disassembling, it is necessary to press the two rebound buttons to squeeze the marble out of the slot through the spring compression, and then pull out the electronic pen fixing buckle to remove it. The spring on the rebound button realizes the resilience of the button, and the spring under the marble realizes the extrusion and the tension of the spring itself, squeezing the marble into the slot and compressing it back to the groove of the buckle rod. The marble realizes the function of fixing the buckle rod to fix the watch frame 30.

[0026] In addition, two feed cables are separated from the mainboard of the smart watch, and the cable cables include a first cable 60 and a second cable 61, wherein the first cable 60 is electrically connected to the feed point 40, and the second cable 61 is electrically connected to the ground point 50. Preferably, the feed point 40 is configured as a metal thimble; and the ground point 50 is configured as a metal thimble. In other words, the two feed cables are separated from the mainboard of the movement and connected to the antenna of the electronic pen cavity 22 through the metal thimble of the watch frame 30. Such a setting can reduce the influence and interference of various electronic devices and screen batteries inside the movement on the antenna, and the radiation performance of the antenna is much better than that of the built-in frame antenna. As the movement mechanism of existing smart watches becomes more and more complex with the increase of functions, the space inside the movement is small. The device has a greater impact on the built-in antenna, which generally has a negative impact on the performance of the antenna. The external antenna has fewer interferences and a better environment, so the antenna performance will naturally be improved.

[0027] The external antenna is configured as a combined single-pole antenna, an IFA antenna or a loop antenna. The external antenna is configured as a MAD antenna or an LDS antenna or a PDS patch antenna. The external antenna is configured as an IFA antenna, including a first radiating branch and a second radiating branch, wherein the first radiating branch controls the resonance of the 1575MHz frequency band. The first radiating branch and the second radiating branch are electrically connected, and the first radiating branch and the second radiating branch share a return point, and the feeding point 40 excites the first radiating branch to radiate, and the first radiating branch couples with the second radiating branch and transfers radiation energy.

[0028] This arrangement makes the overall efficiency of the external antenna better, the upper hemisphere drop is within 3dB, the antenna has a relatively wide bandwidth and good consistency, and solves the technical problem of poor performance in the upper hemisphere of the antenna. In addition, the ground access points between antennas are reduced, that is, a common ground solution is adopted to save space in the antenna environment, increase the motherboard clearance to achieve the purpose of improving antenna performance; at the same time, reducing one antenna return spring can also reduce design costs, and at the same time, it can also increase the clearance of two or more antennas on the motherboard, which is beneficial to antenna performance.

[0029] In summary, the utility model provides a smart watch, which includes a watch strap and a dial, wherein the dial includes a built-in mainboard 10, an external electronic pen 20, and a watch frame 30 connected to the external electronic pen 20; the built-in mainboard 10 is electrically connected to the external electronic pen 20, the external electronic pen 20 includes a pen holder 21 and a pen cavity 22, the pen holder 21 is inserted and placed in the pen cavity 22, and the pen cavity 22 is provided with an external antenna; the pen cavity 22 is connected to the watch frame 30 through a connecting component, a feeding point 40 and a grounding point 50 are provided on the pen cavity 22, the built-in mainboard 10 leads out a cable line to connect the feeding point 40 and the grounding point 50; the external antenna shares a return point to increase the net space of the external antenna.
