Description

Technical Field

[0001] The present invention relates to the field of antenna technology, and in particular to a terminal device antenna system and a control method, device, equipment and storage medium thereof. Background Art

[0002] At present, the antenna of the terminal device is a fixed-position antenna, that is, the position of the antenna is designed in the terminal development stage, and the antenna will not be changed after it is set in this position. The problem that follows is that the user may block the antenna position when using the terminal device, making the antenna signal weaker and affecting the communication effect of the terminal device. For example: when using a smartphone, the user will hold the smartphone in his hand. However, the user's holding the smartphone and the user's holding the smartphone to the ear are all normal ways of using the smartphone. However, the user's hand and the user's head will have an adverse effect on the antenna performance of the smartphone, making the antenna signal of the smartphone weaker, causing the signal to be temporarily disconnected or the signal quality to be poor in application scenarios such as using the smartphone to make calls. If it is during some important calls or video communications, the communication signal strength will be affected by the obstruction, which will easily cause communication misunderstandings or fail to achieve good communication results.

Detailed implementation manners

[0030] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] According to an embodiment of the present invention, an antenna system for a terminal device is provided. As Figure 1 shown, it is a structural diagram of the antenna system of a terminal device according to an embodiment of the present invention.

[0032] The antenna system of the terminal device includes: a feed point track and a driving device 4.

[0033] The feed point track includes: a U-shaped track 1, a metal coil 2, and a feed point unit 3. Among them, the metal coil 2 is placed inside the U-shaped track 1; a plurality of hollow positions are opened on the inner ring side wall of the U-shaped track 1, and each hollow position is provided with the feed point unit 3.

[0034] The feed point track is disposed in the middle frame of the terminal device. Each of the feed point units 3 is connected to the antenna circuit of the terminal device.

[0035] The driving device 4 is respectively connected to the feed point track and the controller of the terminal device.

[0036] Under the control of the controller, the driving device 4 drives the metal coil 2 to move inside the U-shaped track 1 so that the metal coil 2 is connected to the feed point units 3 at different positions on the inner ring side wall of the U-shaped track 1.

[0037] In the embodiment of the present invention, a feed point track and a driving device 4 are provided in the terminal device. A metal coil 2 with a movable position and a plurality of feed point units 3 connected to the antenna circuit of the terminal device are provided in the feed point track. In this way, when the communication signal strength is weak, the driving device 4 can be controlled to drive the metal coil 2 to move in the track, connect the feed point units 3 at other positions, and avoid the feed point units 3 blocked by body parts, thereby improving the communication signal strength.

[0038] Specifically for the feed point track:

[0039] The feed point track is integrally disposed in the middle frame of the terminal device; or, the feed point track with an independent structure is disposed along the inner side wall of the middle frame of the terminal device.

[0040] The U-shaped track 1 in the feed point track is a non-closed track. The U-shaped track 1 can be used as a part of the middle frame of the terminal device and integrated inside the middle frame. An opening is provided at a position on the inner side wall of the middle frame where the driving device 4 needs to be connected to expose the two track openings of the U-shaped track 1. Of course, the U-shaped track 1 can also be used as an independent pipe and disposed along the middle frame of the terminal device.

[0041] The distance between any two adjacent feed point units 3 in the feed point track is equal. In this way, under a certain air flow pressure or when the conveyor chain 22 moves at a constant speed, the movement time of the metal coil 2 from any feed point unit 3 to the next feed point unit 3 is the same.

[0042] The number of metal coils 2 in the feed point track is at least one. The metal coil 2 can be a copper coil. The metal coil 2 is filled into the feed point track through semiconductor processes and injection molding processes. The feed point track reserves a uniform and sufficient space (U-shaped track 1) to facilitate the movement of the metal coil 2 in the track. The cross-section of the U-shaped track 1 can be circular or square.

[0043] The diameter of the internal pipe of the U-shaped track 1 is uniform everywhere and the inner wall is smooth, so that the metal coil 2 can move freely under the action of air pressure. Further, there is a tolerance between the diameter (or side length) of the internal pipe of the U-shaped track 1 and the diameter of the metal coil 2, and the diameter (or side length) of the internal pipe of the U-shaped track 1 is greater than the diameter of the metal coil 2.

[0044] Specifically for the feed point unit 3:

[0045] The feed point unit 3 is an antenna feed patch. The number of the feed point units 3 is multiple.

[0046] Each feed point unit 3 is connected to the antenna matching automatic adjustment circuit (antenna circuit) of the terminal device. As Figure 2 shown, it is a schematic diagram of the antenna matching automatic adjustment circuit according to an embodiment of the present invention.

[0047] The antenna matching automatic adjustment circuit includes: an RF (Radio Frequency) system 5, an LNA (Low Noise Amplifier) module 6, a PA (Power Amplifier) module 7, and a duplexer 8. The duplexer 8 is used to connect the feed point unit 3. Among them, Figure 2 the arrow in the figure is the position for connecting the feed point unit 3.

[0048] After the metal coil 2 is connected to the feed point unit 3, the metal coil 2, the feed point unit 3, and the antenna matching automatic adjustment circuit form a complete terminal antenna, and this terminal antenna can be used for signal transmission and reception.

[0049] When receiving a signal, the signal passes through the metal coil 2, the feed point unit 3, the duplexer 8, and the LNA module 6, and reaches the RF system 5, and the RF system 5 processes the signal into the information required by the terminal device.

[0050] When sending a signal, the signal passes through the RF system 5, the PA module 7, the duplexer 8, and the feed point unit 3, and reaches the metal coil 2, and the metal coil 2 sends out the signal.

[0051] Specifically for the driving device 4:

[0052] The driving device 4 includes: a transmission mechanism 9, a stepping motor 10, and a driving chip 11. The driving device 4 can refer to Figure 3 the specific structure diagram of the terminal device antenna system shown in the figure.

[0053] The transmission mechanism 9 is respectively connected to the stepping motor 10 and the U-shaped track 1.

[0054] The driving chip 11 is respectively connected to the controller and the stepping motor 10, and under the control of the controller, supplies power to the stepping motor 10 to drive the transmission mechanism 9 by the stepping motor 10.

[0055] Driven by the stepping motor 10, the transmission mechanism 9 drives the metal coil 2 to move inside the U-shaped track 1.

[0056] Next, the specific implementation structure of the driving device 4 will be further described.

[0057] In an embodiment, the top view of the driving device 4 is as shown in Figure 4 shown, and the right view of the driving device 4 is as shown in Figure 5 shown.

[0058] In the driving device 4, the transmission mechanism 9 includes: a transmission component, a first piston device 12 and a second piston device 13. Among them, the other components of the transmission mechanism 9 except the first piston device 12 and the second piston device 13 are transmission components. The first distance is equal to the second distance. The first distance refers to the distance from the top of the cylinder to the bottom end of the first rotating rod 20 in the first piston device 12. The second distance refers to the distance from the top of the cylinder to the bottom end of the second rotating rod 21 in the second piston device 13.

[0059] The first piston device 12 is arranged at the first track opening of the U-shaped track 1; a first communication port is provided at the top of the cylinder of the first piston device 12 and is communicated with the U-shaped track 1 through the first communication port.

[0060] The second piston device 13 is arranged at the second track opening of the U-shaped track 1; a second communication port is provided at the top of the cylinder of the second piston device 13 and is communicated with the U-shaped track 1 through the second communication port.

[0061] The first piston device 12 and the second piston device 13 enclose the U-shaped track 1 to make the U-shaped track 1 a closed pipeline.

[0062] The transmission component is respectively connected to the stepping motor 10, the first piston device 12 and the second piston device 13. Driven by the stepping motor 10, it drives the first piston device 12 to pump air from the U-shaped track 1 and drives the second piston device 13 to supply air to the U-shaped track 1, or drives the first piston device 12 to supply air to the U-shaped track 1 and drives the second piston device 13 to pump air from the U-shaped track 1, so that the metal coil 2 inside the U-shaped track 1 moves.

[0063] Specifically, the stepper motor 10 includes a stepper motor 14 and a stepper gear 15 that are connected to each other; the stepper motor 14 is connected to the drive chip 11. Further, the stepper motor 14 is controlled by a pulsed current.

[0064] The transmission member includes a first rotating wheel 16, a second rotating wheel 17, a connecting rod 18, and a piston gear 19.

[0065] A first rotating rod 20 in the first piston device 12 is movably connected to the first rotating wheel 16.

[0066] A second rotating rod 21 in the second piston device 13 is movably connected to the second rotating wheel 17.

[0067] The connecting rod 18 connects the piston gear 19, the first rotating wheel 16, and the second rotating wheel 17 in series; wherein, the piston gear 19, the first rotating wheel 16, and the second rotating wheel 17 in different planes are parallel to each other; the connecting lines of the mapping points of the first connection point, the second connection point, and the third connection point in the same plane form 180 degrees; the first connection point is the connection point of the first rotating rod 20 and the first rotating wheel 16; the second connection point is the connection point of the first rotating wheel 16 or the second rotating wheel 17 and the connecting rod 18; the third connection point is the connection point of the second rotating rod 21 and the second rotating wheel 17.

[0068] The piston gear 19 meshes with the stepper gear 15.

[0069] When the drive chip 11 supplies power to the stepper motor 14, the stepper motor 14 drives the stepper gear 15 to rotate, and the stepper gear 15 drives the piston gear 19 to rotate.

[0070] Driven by the piston gear 19, the first rotating wheel 16 drives the first piston device 12 to perform a piston motion and the second rotating wheel 17 drives the second piston device 13 to perform a piston motion.

[0071] In this embodiment, the connecting lines of the mapping points of the first connection point, the second connection point, and the third connection point in the same plane form 180 degrees, that is, the first connection point and the third connection point are in a 180-degree corresponding phase on the two rotating wheels, which enables the first piston device 12 to draw air from the U-shaped track 1 through the first communication port and the second piston device 13 to supply air to the U-shaped track 1 through the first communication port, or the first piston device 12 to supply air to the U-shaped track 1 through the first communication port and the second piston device 13 to draw air from the U-shaped track 1 through the first communication port.

[0072] Specifically, the stepping motor 14 is controlled by a pulsed current. The number of rotations of the stepping motor 14 can be controlled by the power supply duration of the pulsed current. The rotation of the stepping motor 14 drives the rotation of the stepping gear 15, and the piston gear 19 rotates along with the rotation of the stepping gear 15. The rotation of the piston gear 19 drives the rotation of the first rotating wheel 16 and the second rotating wheel 17. The first rotating rod 20 and the second rotating rod 21 pull and push, respectively, to achieve the air extraction of the first piston device 12 and the air supply of the second piston device 13.

[0073] When the first rotating rod 20 pulls the piston to move leftward and the second rotating rod 21 pushes the piston to move rightward, an air flow in the direction from the second piston device 13 to the first piston device 12 is formed in the U-shaped track 1. This air flow pushes the metal coil 2 to move from the second piston device 13 to the first piston device 12.

[0074] When the first rotating rod 20 pushes the piston to move rightward and the second rotating rod 21 pulls the piston to move leftward, an air flow in the direction from the first piston device 12 to the second piston device 13 is formed in the U-shaped track 1. This air flow pushes the metal coil 2 to move from the first piston device 12 to the second piston device 13.

[0075] Furthermore, in the first piston device 12, a first air exchange hole is provided on the side wall of the cylinder between the top of the piston and the top of the cylinder. In the second piston device 13, a second air exchange hole is provided on the side wall of the cylinder between the top of the piston and the top of the cylinder. When the pistons in both the first piston device 12 and the second piston device 13 reach their limits, that is, when both rotating wheels have rotated more than half, the first air exchange hole and the second air exchange hole are opened, allowing the air between the top of the piston and the top of the cylinder to communicate with the external air, so as to ensure the next air extraction and air supply.

[0076] In this embodiment, since the first piston device 12 and the second piston device 13 seal the two track openings of the U-shaped track 1, the U-shaped track 1 is a well-sealed track. The controller of the terminal device controls the drive chip 11 according to the communication signal strength between the radio frequency system and the base station communication system, so that the drive chip 11 drives the stepping motor 10 to rotate. Then, through the stepping gear 15 and the piston gear 19, the first rotating wheel 16 and the second rotating wheel 17 are driven to rotate, realizing the piston suction and pushing the metal coil 2 inside the sealed U-shaped track 1 to move.

[0077] In another embodiment, the structural diagram of the driving device 4 is as Figure 6 shown.

[0078] In the driving device 4, the stepping motor 10 includes a stepping motor 14 and a stepping gear 15 that are connected to each other.

[0079] In the driving device 4, the transmission mechanism 9 includes a transmission chain 22 made of an insulating material.

[0080] The stepper motor 14 is connected to the driving chip 11.

[0081] The transmission chain 22 is arranged on the outer edge of the stepper gear 15, passes through the U-shaped track 1, and is connected to the metal coil 2 in the U-shaped track 1. To make the internal connection relationship in the U-shaped track 1 clearer, a perspective view is used to represent the inside of the U-shaped track 1. The metal coil 2 can be snapped onto the transmission chain 22.

[0082] When the driving chip 11 supplies power to the stepper motor 14, the stepper motor 14 drives the stepper gear 15 to rotate, and the stepper gear 15 drives the transmission gear to rotate, so that the transmission chain 22 drives the metal coil 2 in the U-shaped track 1 to move.

[0083] For the above terminal device antenna system, an embodiment of the present invention further provides a control method for the terminal device antenna system. As Figure 7 shown, it is a flowchart of a control method for a terminal device antenna system according to an embodiment of the present invention.

[0084] Step S710, read the communication signal strength of the terminal device antenna system.

[0085] Step S720, compare the communication signal strength with a preset signal strength threshold.

[0086] Step S730, when the communication signal strength is less than the preset signal strength threshold, output a current output signal to the driving device of the terminal device antenna system to control the operation of the driving device, so that the driving device drives the metal coil in the terminal device antenna system to move inside the U-shaped track until the communication signal strength of the terminal device antenna system is greater than or equal to the signal strength threshold.

[0087] The following provides two ways to output current output information to the driving device. Of course, the following two ways are only for illustrating the embodiments of the present invention and are not used to limit the embodiments of the present invention.

[0088] Way 1, when outputting a current output signal to the driving device, determine in real time whether the communication signal strength is less than the signal strength threshold; if so, continue to output a current output signal to the driving device; if not, stop outputting a current output signal to the driving device.

[0089] Mode 2: Output a current output signal to the driving device for a preset time. The preset time is the movement time of the metal coil from one feeding point unit of the terminal device antenna system to the next feeding point unit. Further, since the distances between any two adjacent feeding point units in the feeding point track are equal, the movement time of the metal coil from any feeding point unit to the next feeding point unit is the same when the air flow pressure is constant or when the conveyor chain moves at a constant speed. The movement time of the metal coil from any feeding point unit to the next feeding point unit can be obtained through pre-measurement and verification.

[0090] After outputting the current output signal to the driving device of the terminal device antenna system, the driving chip in the driving device receives the current output signal and starts to output a pulsed current to the driving motor. The driving motor drives the transmission mechanism to work, driving the metal coil in the feeding point track to move from the current feeding point unit to the next feeding point unit.

[0091] Further, after the driving chip outputs the pulsed current to the driving motor, the driving motor in the driving motor starts to work, driving the driving gear to rotate, causing the piston gear, the first rotating wheel, and the second rotating wheel to rotate accordingly, and then enabling the first piston device and the second piston device to start piston movement, generating an air flow in the U-shaped track, and causing the metal coil in the U-shaped track to move to the next feeding point unit under the action of the air flow pressure. Alternatively, after the driving chip outputs the pulsed current to the driving motor, the driving motor in the driving motor starts to work, driving the driving gear to rotate, and the driving gear drives the conveyor chain to move at a constant speed, causing the conveyor chain to drive the metal coil to the next feeding point unit.

[0092] In this embodiment, the controller of the terminal device has a learning ability. When stopping outputting the current output signal to the driving device, record the information of the feeding point unit connected to the metal coil; according to the recorded information, determine the feeding point unit to which the metal coil is most connected; when the terminal device is awakened, by outputting the current output signal to the driving device, cause the driving device to drive the metal coil to move to the position of the feeding point unit to which it is most connected.

[0093] Specifically, a unique code can be set for each feed point unit in advance, and the initial feed point unit where the metal coil is located can be set. Since the time for the metal coil to move from one feed point unit to another is known, when outputting a signal through the output current to change the feed point unit linearly connected by the metal, the unique code of the feed point unit where the metal coil stays when the current output signal stops being sent can be recorded; according to the recorded information, the feed point unit with the most stays (connections) of the metal coil is determined, that is: the feed point unit with the most recorded unique codes. Each time the terminal device is awakened, by outputting a current output signal to the driving device, the metal coil is moved to the feed point unit with the most stays, so that the metal coil is connected to the feed point unit with the strongest signal, thereby directly bringing the communication signal strength of the terminal device to the best state.
