[0036] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0038] Reference Figure 1-Figure 3 The present application discloses a mobile terminal 100, for example, the mobile terminal 100 can be a mobile phone, a tablet computer or a digital television. The mobile terminal 100 includes a body 40, a stylus 10 and a radio frequency component 5. For example, the radio frequency component 5 is used to receive and send satellite signals to communicate with the satellite. A storage slot 41 is provided on the body 40, and the storage slot 41 is adapted to the stylus 10, and the storage slot 41 is used to store the stylus 10. A radiation wire is provided on the stylus 10, and the radio frequency component 5 and the radiation wire can be electrically connected so that the radiation wire can be used as a radiator, so that the stylus 10 can be used as an external antenna, thereby improving the signal gain of the radio frequency component 5, so that the radio frequency component 5 can reliably receive and send satellite signals, and expand the effective communication distance between the radio frequency component 5 and the satellite antenna.

[0039] Reference Figure 6 The RF component 5 includes a baseband chip 52, a signal transmitting circuit 53, a signal receiving circuit 54 and a satellite antenna 55. The baseband chip 52 has a signal transmitting module 521 and a signal receiving module 522. The satellite signal emitted by the signal transmitting module 521 can be transmitted to the satellite antenna 55 through the signal transmitting circuit 53, and then transmitted to the satellite through the satellite antenna 55; the satellite signal received by the satellite antenna 55 can be transmitted to the signal receiving module 522 through the signal receiving circuit 54.

[0040] For example, the signal transmission circuit 53 may include a first filter 531 and a satellite power amplifier 532 (Staellite PA) electrically connected in sequence, wherein the first filter 531 is used to filter the satellite signal emitted by the signal transmission module 521 to shield the signal outside the preset transmission bandwidth and improve the communication quality; specifically, the frequency range of the preset transmission bandwidth can be set to be greater than or equal to 235M and less than or equal to 240M. The satellite power amplifier 532 is used to amplify the strength of the satellite signal emitted by the signal transmission module 521 to expand the effective communication distance between the RF component 5 and the satellite antenna 55.

[0041] Specifically, the signal transmitting circuit 53 may also include a signal coupler 533 (CPLR), which is connected between the satellite antenna 55 and the satellite power amplifier 532. The baseband chip 52 also includes a signal strength detection module 523 (PDET), which is connected to the signal coupler 533. After the signal coupler 533 receives the amplified satellite signal, it can transmit the signal to the satellite antenna 55 and the signal strength detection module 523 respectively. The signal strength detection module 523 can detect the signal strength of the received satellite signal and adjust the signal strength of the signal transmitting module 521 when transmitting the signal according to the signal strength, so as to limit the signal strength within a preset range and reduce the risk of damage to the signal transmitting circuit 53.

[0042] For example, the signal transmission module 521 may include multiple signal transmission modules 5211, each of which can transmit satellite signals outward, and each of which can be used individually. When the signal strength detection module 523 detects that the signal strength emitted by the signal coupler 533 is weak, the baseband chip 52 can control multiple signal transmission modules 5211 to transmit satellite signals simultaneously to increase the signal strength.

[0043] Reference Figure 6 The signal receiving circuit 54 includes a second filter 541, a low noise power amplifier 542 (Low Noise Amplifier) ​​and a third filter 543 connected in sequence. The second filter 541 is connected to the signal transmitting module 521, and the third filter 543 is connected to the antenna. The satellite signal received by the satellite antenna 55 can pass through the third filter 543, the low noise power amplifier 542 and the second filter 541 in sequence, and finally be transmitted to the signal receiving module 522 of the baseband chip 52.

[0044] The third filter 543 is used to filter the satellite signals received by the satellite antenna 55 to shield the signals outside the preset transmission bandwidth and improve the communication quality; specifically, the frequency range of the preset transmission bandwidth can be set to be greater than or equal to 280M and less than or equal to 283M.

[0045] The low noise power amplifier 542 is used to amplify the satellite signal filtered by the third filter 543 so that the baseband chip 52 can receive and identify relatively weak satellite signals, thereby extending the effective communication distance between the RF component 5 and the satellite antenna 55.

[0046] The second filter 541 is used to filter the satellite signal amplified by the low noise power amplifier 542, shield the signal outside the preset transmission bandwidth, and shield the interference signal amplified by the low noise power amplifier 542 to further improve the communication quality.

[0047] For example, the signal receiving module 522 may include two differential signal input terminals (RXP\RXN). The satellite signal filtered by the second filter 541 may be converted into two signals with the same amplitude and opposite phases, and transmitted to the signal receiving module 522 respectively. This can reduce the interference received by the signal receiving module 522 when receiving the satellite signal, thereby achieving signal gain amplification.

[0048] Reference Figure 1 and Figure 2 The present application discloses a stylus pen 10 including: a pen tip 1, a pen body 2 and a pen cap 3, wherein the pen body 2 is provided with a radiating wire, and one end of the pen body 2 is connected to the pen tip 1; for example, a touch component may be provided in the pen tip 1 so that the stylus pen 10 has a handwriting function.

[0049] The pen cap 3 is sleeved on the end of the pen body 2 away from the pen tip 1 , that is, the projection of the pen body 2 on the projection plane completely falls into the projection of the pen cap 3 on the projection plane, wherein the projection plane is perpendicular to the extension direction of the pen body 2 .

[0050] For example, the storage slot 41 may include a slot body 42 and a pen cap slot 43, the pen cap slot 43 is adapted to the pen cap 3, and the pen cap slot 43 is used to accommodate the pen cap 3, the slot body 42 is adapted to the pen body 2 and the pen tip 1 of the stylus 10, and the slot body 42 is used to accommodate the pen body 2 and the pen tip 1.

[0051] When a storage slot 41 for accommodating the stylus 10 is provided on the mobile terminal 100, since the pen cap 3 is mounted on the end of the pen shaft 2 away from the pen tip 1, in order to reduce the space occupied by the storage slot 41, the inner diameter of the slot body 42 for accommodating the pen shaft 2 and the pen tip 1 can be set to be smaller than the inner diameter of the pen cap slot 43 for accommodating the pen cap 3.

[0052] A connection part 31 is provided on the outer surface of the pen cap 3, and the connection part 31 is electrically connected to the radiation wire. The connection part 31 is used to electrically connect the RF component 5 in the mobile terminal 100; for example, the connection part 31 can be used to connect the satellite antenna 55 and the radiation wire. The pen cap 3 can be inserted upside down into the pen cap slot 43, the connection part 31 is electrically connected to the RF component 5, and the radiation wire is connected to the RF component 5, so that the radiation wire can be used as a radiator, and the overall length of the antenna of the RF component 5 is extended, so that the stylus 10 can be used as an external antenna, the signal gain of the RF component 5 is improved, so that the RF component 5 can reliably receive and send satellite signals, and the effective communication distance between the RF component 5 and the satellite antenna is extended.

[0053] By sleeve-arranging the pen cap 3 on the end of the pen barrel 2 away from the pen head 1, when the pen cap 3 is inserted upside down into the pen cap slot 43, the bottom surface of the pen cap slot 43 can limit the pen cap 3, so that the pen cap 3 can be reliably positioned relative to the mobile terminal 100, with a simple structure and convenient use. Moreover, in this way, it is unnecessary to provide an additional slot hole electrically connected to the radiation wire on the mobile terminal 100, and it is unnecessary to provide an additional limiting structure for positioning the stylus 10 under the external antenna on the mobile terminal 100, so that the overall structure of the mobile terminal 100 is simple and compact.

[0054] According to the stylus pen 10 provided by the embodiment of the present disclosure, by sleeve-arranging the pen cap 3 on the pen barrel 2, the diameter of the pen cap 3 is larger than the diameter of the pen barrel 2, the pen cap 3 can be inserted upside down into the pen cap groove 43, the connecting portion 31 is electrically connected to the RF component 5, and the radiating wire is connected to the RF component 5, so that the radiating wire can be used as a radiator, and the overall length of the antenna of the RF component 5 is extended, so that the stylus pen 10 can be used as an external antenna, the signal gain of the RF component 5 is improved, so that the RF component 5 can reliably receive and send satellite signals, and the effective communication distance between the RF component 5 and the satellite antenna is improved, and the bottom surface of the pen cap groove 43 can be used to limit the pen cap 3, so that the pen cap 3 can be reliably positioned relative to the mobile terminal 100, the structure is simple, and the use is convenient, and in this way, it is unnecessary to additionally provide a slot hole electrically connected to the radiating wire on the mobile terminal 100, and it is unnecessary to additionally provide a limiting structure for positioning the stylus pen 10 under the external antenna on the mobile terminal 100, so that the overall structure of the mobile terminal 100 is simple and compact.

[0055] Reference Figure 2-Figure 3 According to some embodiments provided by the present disclosure, the connecting portion 31 is annularly sleeved on the radially outer side of the pen cap 3. For example, referring to Figure 4 and Figure 5 The end of the radiation wire away from the pen tip 1 can be arranged on the end surface of the pen body 2 away from the pen tip 1, and the pen cap 3 can be built with an electrical connection conductor 33, which is connected to the connecting part 31 and the radiation wire.

[0056] Specifically, the electrical connecting conductor 33 includes a first conductive part 331 and a second conductive part 332. The first conductive part 331 is arranged at one end of the pen shaft 2 away from the pen tip 1, and the first conductive part 331 is connected to the connecting part 31. The second conductive part 332 extends along the axial direction of the pen shaft 2. One end of the second conductive part 332 in the extension direction is connected to the first conductive part 331, and the other end is used to electrically connect the radiation wire.

[0057] Optionally, the first conductive part 331 may be disc-shaped, the connecting part 31 is arranged around the first conductive part 331, and the end of the second conductive part 332 away from the pen body 2 is connected to the center position of the first conductive part 331, that is, the electrical connecting conductor 33 is arranged in a flat pushpin shape.

[0058] Optionally, the first conductive part 331 and the second conductive part 332 can both be conductive wires, the first conductive part 331 extends radially along the pen cap, the second conductive part 332 extends circumferentially along the pen body 2, one end of the first conductive part 331 is connected to the connecting part 31, and the other end of the first conductive part 331 is connected to an end of the second conductive part 332 away from the pen body 2, and the electrical connection conductor 33 is arranged in an L shape.

[0059] Optionally, when the first conductive part 331 and the second conductive part 332 are both conductive wires, the first conductive part 331 extends radially of the pen cap, and the second conductive part 332 extends circumferentially of the pen shaft 2. Both ends of the first conductive part 331 can be connected to the connecting part 31, and one end of the second conductive part 332 away from the pen shaft 2 is connected to the center position of the second conductive part 332 connected to the first conductive part 331, and the electrical connecting conductor 33 is arranged in a T shape.

[0060] The connecting portion 31 is arranged on the radially outer side of the pen cap 3, so that the connecting portion 31 can have a certain width in the axial direction of the stylus 10. When the distance that the stylus 10 moves along the axial direction is not greater than the width of the connecting portion 31 in the axial direction of the stylus 10, the connecting portion 31 can still maintain electrical connection with the RF component 5, thereby ensuring the reliability of the electrical connection between the radiating wire and the RF component 5. In this way, the position accuracy of the connecting portion 31 and the radiating arm contact piece 51 does not need to be set high, thereby reducing the difficulty of the production process and the assembly process, improving the production efficiency, and reducing the production cost.

[0061] Reference Figure 1-Figure 3 According to some embodiments provided by the present disclosure, the radiation wire is embedded in the pen body 2; for example, the pen body 2 may be a circuit board, and the radiation wire is a circuit etched on the pen body 2, that is, the pen body 2 and the radiation wire may be made by LDS antenna technology. This can prevent the radiation wire from being exposed and abraded, and can prevent the radiation wire from being electrically connected to an external conductor and affecting the benefit of the radiation wire when used as a radiator, thereby extending the service life of the radiation wire and improving the reliability of the stylus 10.

[0062] Reference Figure 1-Figure 3 According to some embodiments provided by the present disclosure, at least part of the radiation wire is exposed to the outer surface of the pen holder 2; for example, the radiation wire can completely cover the outer surface of the pen holder 2; for another example, the radiation wire can be used as the pen holder 2 of the stylus 10. In this way, the shielding of the radiation wire by the pen holder 2 can be reduced, and the radiation gain of the radiation wire can be improved.

For example, the positioning member 32 and the limiting member 6 can be mutually matched buckle structures. In this way, the stylus 10 can be reliably positioned relative to the body 40, and the stylus 10 can be prevented from shaking relative to the body 40, so that the connection portion 31 is reliably connected to the RF component 5, and the radiation wire can be reliably connected to the RF component 5, thereby improving the reliability of the stylus 10.

[0064] Reference Figure 1-Figure 3 According to some embodiments provided by the present disclosure, the positioning member 32 is a magnetic member, and the positioning member 32 is disposed inside the pen cap 3. For example, the positioning member 32 may be a magnet or an iron block. When the positioning member 32 is a magnet, the limiting member 6 may be a magnet or an iron block; when the positioning member 32 is an iron block, the limiting member 6 may be a magnet. Magnetic matching can reduce the difficulty of processing the clamping structure, avoid wear caused by mutual friction between the positioning member 32 and the limiting member 6 during multiple uses, so that the stylus 10 can be reliably positioned relative to the mobile terminal 100, and improve the reliability of the mobile terminal 100.

For example, the radiation arm contact piece 51 can be a metal spring sheet. When the radiation arm contact piece 51 is a metal spring sheet, the radiation arm contact piece 51 can be a copper sheet, an iron sheet, or an aluminum sheet. The elastic contact can make the radiation arm contact piece 51 reliably electrically connected to the connection part 31, so that the radiation wire can be reliably connected to the radio frequency component 5.

[0068] Reference Figure 1-Figure 3 According to some embodiments provided by the present disclosure, the radiating arm contact piece 51 is disposed at the opening of the pen cap slot 43; for example, the connecting portion 31 can be disposed at one end of the pen cap 3 close to the pen tip 1. In this way, the radiating wire can be connected to the radio frequency component 5 only when the pen cap 3 is inserted into the pen cap slot 43, which can effectively prevent the stylus pen 10 from being connected to the radio frequency component 5 in the stored state and increase the energy consumption of the mobile terminal 100, thereby reducing the energy consumption of the mobile terminal 100 when the stylus pen 10 is in the stored state, improving the battery life of the mobile terminal 100, and improving the overall performance of the mobile terminal 100.

For example, the connection portion 31 can be disposed at the end of the pen cap 3 away from the pen tip 1. In this way, the radiation wire can be connected to the radio frequency component 5 only when the pen cap 3 is inserted into the pen cap slot 43, which can effectively prevent the stylus pen 10 from being connected to the radio frequency component 5 in the stored state and increase the energy consumption of the mobile terminal 100, thereby reducing the energy consumption of the mobile terminal 100 when the stylus pen 10 is in the stored state, improving the battery life of the mobile terminal 100, and improving the overall performance of the mobile terminal 100.

That is, the stopper 6 is arranged at the middle position of the cap slot 43, and the corresponding positioning member 32 also needs to be arranged at the middle position of the cap 3.

[0072] When the stylus pen 10 needs to be stored and the stylus pen 10 is inserted into the storage slot 41 in the normal direction, that is, the pen head 1 is inserted into the end of the slot body 42 away from the pen cap slot 43, the limiting member 6 and the positioning member 32 can cooperate with each other to limit the stylus pen 10; when the stylus pen 10 needs to be used as an external antenna to use enhanced signals and the stylus pen 10 is inserted into the storage slot 41 in reverse direction, that is, the pen cap 3 is inserted in reverse direction into the pen cap slot 43, the limiting member 6 and the positioning member 32 can cooperate with each other to limit the stylus pen 10.
