For example, the electronic devices can realize wireless communication with near field communication (NFC) cards, wireless charging stations and other devices based on the coil antennas. The principle of wireless communication between the coil antenna of the electronic device and the external device is to align the end faces of the coil antenna of the electronic device with the coil antenna of the external device, so that the magnetic flux lines in one of the coil antennas can penetrate into the inside of the other coil antenna, thereby realizing wireless communication. However, when the coil antenna of the external device and the coil antenna of the electronic device are different in shape and size, it may cause the problem of failure to establish a wireless communication connection. Summary of the invention

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0019] The antenna and electronic device provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0020] The antenna in the embodiment of the present application can be applied to electronic devices, and the electronic devices can communicate wirelessly with external devices based on the antenna. When establishing a wireless communication connection between the electronic device and the external device in this way, it is necessary to ensure that the end faces of the two coil antennas are aligned. Among them, the external device can be a wireless charging base, various NFC cards, RFID cards, etc. Since the shapes and sizes of various cards are varied, and even there are special-shaped cards, the shapes and sizes of the coil antennas of the external devices are varied. In the related art, the shapes and sizes of the coil antennas in the electronic devices are relatively fixed. Therefore, when an external device with coil antennas of different shapes and sizes is used to establish a connection with the electronic device, there may be a problem of poor alignment between the coil antennas in some external devices and the coil antennas of the electronic device, which may lead to the problem of failure to establish the wireless communication connection.

[0021] If the size of the coil antenna in the electronic device is simply enlarged, the magnetic flux lines inside the coil antenna in the electronic device will be sparse and the magnetic field strength will not be concentrated enough, resulting in a poor card reading effect. Correspondingly, if the size of the coil antenna is simply reduced, the magnetic flux lines in the coil antenna will be too concentrated. For small-sized external devices, the difficulty of alignment will be significantly increased, and a slight offset may cause the failure of establishing a wireless communication connection. Based on this, an embodiment of the present application proposes a coil antenna with an adjustable hole cross-sectional area, so that it can adapt to external devices with coil antennas of different shapes and sizes.

[0022] See also Figure 1-6 , an antenna provided by an embodiment of the present application, comprising: a first wiring component 100 and a second wiring component 200, wherein the first wiring component 100 and the second wiring component 200 are stacked and arranged, and the second wiring component 200 can move between a first position and a second position relative to the first wiring component 100;

[0023] The first wiring assembly 100 includes at least one first conductive wire 110, and the second wiring assembly 200 includes at least one second conductive wire 210. The at least one first conductive wire 110 and the at least one second conductive wire 210 are movably connected in a one-to-one correspondence to jointly enclose a coil antenna;

[0024] Wherein, during the movement of the second wiring assembly 200 from the first position to the second position, the cross-sectional area of ​​the inner hole formed by the coil antenna gradually increases;

[0025] When the second wiring assembly 200 moves from the second position to the first position, the cross-sectional area of ​​the inner hole gradually decreases.

[0026] The first wiring assembly 100 and the second wiring assembly 200 may be different parts of the coil antenna, and the first wiring assembly 100 or the second wiring assembly 200 cannot form an independent coil antenna. For example, any coil turn in the coil antenna includes a first conductive wire 110 and a second conductive wire 210.

[0027] During the movement of the second wiring component 200 relative to the first wiring component 100 between the first position and the second position, the first wiring component 100 and the second wiring component 200 may always have an overlapping area, and the first wiring component 100 and the second wiring component 200 always maintain electrical connection through the overlapping area. Figure 2 In one embodiment of the present application, the first wiring component 100 and the second wiring component 200 together enclose a winding coil antenna that gradually expands outward.

[0028] It can be understood that the inner side of the innermost circle of the coil antenna forms the inner hole of the coil antenna. Figure 5-6 As shown, when an electrical signal is passed through the coil antenna, magnetic flux lines are formed in the inner hole of the coil antenna. When the coil antenna of the external device is aligned with the coil antenna of the electronic device, the magnetic flux lines can penetrate into the inner hole of the coil antenna of the external device, thereby realizing signal transmission.

[0029] Specifically, since the coil antennas of external devices have various shapes and sizes, when the electronic device is wirelessly connected or transmitting data with the external device based on the coil antenna, the second wiring component 200 can be controlled to move between the first position and the second position relative to the first wiring component 100 to change the size of the coil antenna. During the movement of the second wiring component 200, the effect of the wireless connection between the electronic device and the external device may change continuously. When the electronic device and the external device have a good wireless connection effect, the second wiring component 200 can be controlled to stop moving, thereby improving the effect of wireless communication between the electronic device and the external device based on the coil antenna. For example, see Figure 5 When the size of the external coil antenna 600 is large, the second wiring assembly 200 can be controlled to move to the second position, see Figure 6 When the size of the external coil antenna 600 is small, the second wiring component 200 can be controlled to move to the first position.

[0030] In addition, during the operation of the coil antenna, the magnetic induction intensity at the center position of the inner hole formed by the coil antenna is the strongest. Therefore, when the center position of the inner hole of the coil antenna of the electronic device is aligned with the center position of the inner hole of the coil antenna of the external device, the wireless communication effect between the electronic device and the external device is best. Based on this, in an embodiment of the present application, the position of the second wiring assembly 200 can also be adjusted to adjust the center position of the inner hole of the coil antenna of the electronic device, so that when the centers of the inner holes of the two coils are not aligned, the centers of the inner holes of the two coils are adjusted to the aligned position. The specific adjustment process is as follows:

[0031] Since the position of the first wiring component 100 remains unchanged during the movement of the second wiring component 200, the center position of the inner hole formed by the coil component will also shift accordingly during the movement of the second wiring component 200. Specifically, during the movement of the second wiring component 200 between the first position and the second position, the center position of the inner hole formed by the coil antenna will shift toward the moving direction of the second wiring component 200. In this way, the center position of the coil antenna can be adjusted.

[0032] In this embodiment, since the cross-sectional area of ​​the inner hole formed by the coil antenna can be scaled, when the coil antenna of the external device and the coil antenna of the electronic device have different shapes and sizes, the size of the cross-sectional area of ​​the inner hole formed by the coil antenna in the electronic device can be adjusted to make the coil antenna of the electronic device match the coil antenna of the external device, thereby improving the effect of wireless communication between the electronic device and the external device based on the coil antenna.

[0033] Optionally, the coil antenna includes a first coil turn, the first coil turn includes a first conductive wire 110 and a second conductive wire 210, wherein in the first coil turn:

[0034] The first conductive line 110 includes a first segment 111, a second segment 112 and a third segment 113 which are connected in sequence, and the first segment 111 is opposite to the third segment 113;

[0035] The first end 211 of the second conductive wire 210 is movably connected to the first segment 111 of the first conductive wire 110, the second end 212 of the second conductive wire 210 is used to be movably connected to an adjacent turn coil inside the first turn coil, the third segment 113 of the first conductive wire 110 is used to be movably connected to an adjacent turn coil outside the first turn coil, and the first turn coil is any turn coil in the coil antenna;

[0036] In which, when the second wiring assembly 200 moves between the first position and the second position, the first end 211 of the second conductive wire 210 moves along the first segment 111 of the first turn coil, and the second end 212 of the second conductive wire 210 moves along the adjacent turn coil outside the first turn coil.

[0037] It can be understood that the first end 211 of the second conductive wire 210 can be electrically connected to the first segment 111 of the first conductive wire 110 while being movably connected to the first segment 111. Correspondingly, the second end 212 of the second conductive wire 210 can be electrically connected to the adjacent turn coil inside the first turn coil while being movably connected to the adjacent turn coil inside the first turn coil; the third segment 113 of the first conductive wire 110 can be electrically connected to the adjacent turn coil outside the first turn coil while being movably connected to the adjacent turn coil outside the first turn coil, thereby forming a conductive coil antenna.

[0038] Specifically, see Figure 3 , the first end 211 of the second conductive wire 210 is electrically connected to the first conductive wire 110 through the first segment 111, and the first end 211 of the second conductive wire 210 can move along the first segment 111 toward or away from the second segment 112. During the movement of the second wiring assembly 200 from the first position to the second position, the first end 211 of the second conductive wire 210 can move along the first segment 111 away from the second segment 112, so that the cross-sectional area of ​​the inner hole formed by the coil antenna gradually increases. During the movement of the second wiring assembly 200 from the second position to the first position, the first end 211 of the second conductive wire 210 can move along the first segment 111 toward the second segment 112, so that the cross-sectional area of ​​the inner hole gradually decreases.

[0039] In one embodiment of the present application, the coil antenna further includes a second coil turn and a third coil turn, wherein the second coil turn and the third coil turn are respectively adjacent to the first coil turn, and the second coil turn is located on the inner side of the first coil turn, and the third coil turn is located on the outer side of the first coil turn;

[0040] The second coil turn and the third coil turn respectively include a first conductive wire 110 and a second conductive wire 210, the second end 212 of the second conductive wire 210 of the first coil turn is movably connected to the third segment 113 of the first conductive wire 110 of the second coil turn, and the third segment 113 of the first conductive wire 110 of the first coil turn is movably connected to the second end 212 of the second conductive wire 210 of the third coil turn.

[0041] Specifically, the second end 212 of the second conductive wire 210 of the first coil is movably connected to the third segment 113 of the first conductive wire 110 of the second coil, and is electrically connected to the third segment 113 of the first conductive wire 110 of the second coil. The third segment 113 of the first conductive wire 110 of the first coil is movably connected to the second end 212 of the second conductive wire 210 of the third coil, and is electrically connected to the second end 212 of the second conductive wire 210 of the third coil.

[0042] During the process of the second wiring assembly 200 moving from the first position to the second position, the second end 212 of the second conductive wire 210 of the first turn coil moves along the third segment 113 of the first conductive wire 110 of the second turn coil toward the side opposite to the second segment 112 of the second turn coil, and the second end 212 of the second conductive wire 210 of the third turn coil moves along the third segment 113 of the first conductive wire 110 of the first turn coil toward the side opposite to the second segment 112 of the first turn coil.

[0043] Optionally, the antenna further includes a first feed source and a second feed source, the coil antenna includes a first connection end located at the innermost side and a second connection end located at the outermost side, the first feed source is electrically connected to the first connection end, and the second feed source is electrically connected to the second connection end.

[0044] Among them, see Figure 2 The antenna may further include a third conductive line 400 and a fourth conductive line 500, the first feed source is electrically connected to the first connection end through the third conductive line 400, and the second feed source is electrically connected to the second connection end through the fourth conductive line 500.

[0045] Specifically, the third conductive wire 400 is electrically connected to the first connection end and can also be movably connected to the first connection end, and the fourth conductive wire 500 is electrically connected to the second connection end and can also be movably connected to the second connection end. In this way, during the movement of the second wiring assembly 200 relative to the first wiring assembly 100, the first connection end can move along the third conductive wire 400, and the second connection end can move along the fourth conductive wire 500. It can be understood that during the movement of the first connection end relative to the third conductive wire 400, the first connection end maintains an electrical connection relationship with the third conductive wire 400; during the movement of the second connection end relative to the fourth conductive wire 500, the second connection end maintains an electrical connection relationship with the fourth conductive wire 500.

[0046] See also Figure 2 and Figure 5The specific manner of the active connection between the first connection end and the third conductive line 400, and the specific manner of the active connection between the second connection end and the fourth conductive line 500, may be the same as the manner of the active connection between the first conductive line 110 and the second conductive line 210, and will not be described again to avoid repetition.

[0047] In this implementation, alternating current can be fed into the coil antenna through the first feed source and the second feed source respectively, so that the current fed into the coil antenna by the two feed sources can oscillate on the coil antenna, thereby improving the field strength of the coil antenna.

[0048] Optionally, the antenna also includes a rolling body 300, which is arranged between the first wiring component 100 and the second wiring component 200, and the first conductive wire 110 and the corresponding second conductive wire 210 are movably connected through at least one of the rolling bodies 300, and the rolling body 300 is used to conduct the corresponding first conductive wire 110 and the second conductive wire 210.

[0049] The rolling body 300 may be a ball bearing with conductive properties. Since the more the number of rolling bodies 300 between the first conductive wire 110 and the second conductive wire 210 is, the larger the flow area between the first conductive wire 110 and the second conductive wire 210 is, the different numbers of rolling bodies 300 may be arranged between the first conductive wire 110 and the second conductive wire 210 according to different application scenarios.

[0050] Specifically, in each turn of the coil antenna, the first end 211 of the second conductive wire 210 is movably connected to the first segment 111 of the first conductive wire 110 through the rolling body 300, the second end 212 of the second conductive wire 210 is used to be movably connected to the adjacent turn of the coil on the inner side of the first turn of the coil through the rolling body 300, and the third segment 113 of the first conductive wire 110 is used to be movably connected to the adjacent turn of the coil on the outer side of the first turn of the coil through the rolling body 300.

[0051] In this embodiment, the movable connection between the first conductive wire 110 and the corresponding second conductive wire 210 is realized based on the rolling body 300. In this way, in the process of the first conductive wire 110 in each turn of the coil moving relative to the second conductive wire 210, the rolling body 300 rolls, thereby improving the smoothness of the movement of the second wiring assembly 200 relative to the first wiring assembly 100. At the same time, the rolling body 300 can maintain the electrical connection relationship between the first conductive wire 110 and the corresponding second conductive wire.

[0052] Optionally, the first wiring assembly 100 further includes a first plate body 120, and at least one first slide groove is provided on the side of the first plate body 120 facing the second wiring assembly 200, and one of the first slide grooves is embedded with a first conductive wire 110, and at least a portion of the rolling body 300 is embedded in the corresponding first slide groove.

[0053] In addition, the second wiring assembly 200 also includes a second plate body 220, and the second plate body 220 is provided with at least one second slide groove on the side facing the first wiring assembly 100, and a second conductive wire 210 is embedded in one of the second slide grooves, and at least a part of the rolling body 300 is embedded in the corresponding second slide groove.

[0054] It can be understood that the shape of the first chute is the same as that of the corresponding first conductive line 110, and the shape of the second chute is the same as that of the corresponding second conductive line 210. For example, see Figure 1 , the first conductive wire 110 is in a "C" shape, and the first conductive wires 110 in the coil antenna are nested with each other. At this time, at least one first groove corresponding to the at least one first conductive wire 110 can be opened on the side of the first plate 120 facing the second wiring component 200, and each first conductive wire 110 can be embedded in the corresponding first groove. Since the rolling body 300 is at least partially embedded in the corresponding first groove, the rolling body 300 can contact the first conductive wire 110 in the first groove.

[0055] Accordingly, please see further Figure 1 , the second conductive wire 210 is in an inverted "C" shape, and the second conductive wires 210 in the coil antenna are nested with each other. At this time, the second plate 220 can be provided with at least one second groove corresponding to the at least one second conductive wire 210 on the side facing the first wiring component 100, and each second conductive wire 210 can be embedded in the corresponding second groove. Since the rolling body 300 is at least partially embedded in the corresponding second groove, the rolling body 300 can contact the second conductive wire 210 in the second groove, thereby realizing the function of conducting the first conductive wire 110 with the corresponding second conductive wire 210 based on the rolling body 300.

[0056] In this embodiment, by setting the first groove and the second groove, it is possible to limit the rolling body 300 and guide the second wiring assembly 200, ensuring that the second wiring assembly 200 can only move back and forth between the first position and the second position.

[0057] Optionally, in the first turn coil: the first segment 111 of the first conductive wire 110 includes a first sub-conductive wire 1111 and a second sub-conductive wire 1112 respectively connected to the second segment 112, a first slideway 1113 arranged along the moving direction of the second wiring assembly 200 is formed between the first sub-conductive wire 1111 and the second sub-conductive wire 1112, the first end 211 of the second conductive wire 210 is located in the first slideway 1113, and at least one of the first sub-conductive wire 1111 and the second sub-conductive wire 1112 is in contact with the first end 211 of the second conductive wire 210.

[0058] Specifically, see Figure 4 The first sub-conductive wire 1111 and the second sub-conductive wire 1112 may be copper wires printed on the surface of the first plate 120, and the first sub-conductive wire 1111 and the second sub-conductive wire 1112 are respectively protruded from the surface of the first plate 120, and the first sub-conductive wire 1111 and the second sub-conductive wire 1112 are arranged in parallel and spaced apart, thereby forming the first slideway 1113 between the first sub-conductive wire 1111 and the second sub-conductive wire 1112. The first end 211 of the second conductive wire 210 may be located in the first slideway 1113, and the second conductive wire 210 may contact the inner wall of the first slideway 1113, thereby realizing the electrical connection between the first conductive wire 110 and the second conductive wire 210.

[0059] Optionally, see Figure 4 In the first turn coil: the third segment 113 of the first conductive wire 110 includes a third sub-conductive wire 1131 and a fourth sub-conductive wire 1132 respectively connected to the second segment 112, and a second slideway 1133 arranged along the moving direction of the second wiring assembly 200 is formed between the third sub-conductive wire 1131 and the fourth sub-conductive wire 1132.

[0060] Specifically, see Figure 4 The third sub-conductive wire 1131 and the fourth sub-conductive wire 1132 can be copper wires printed on the surface of the first board 120, and the third sub-conductive wire 1131 and the fourth sub-conductive wire 1132 are respectively protruded from the surface of the first board 120, and the third sub-conductive wire 1131 and the fourth sub-conductive wire 1132 are parallel and spaced apart, thereby forming the second slide 1133 between the third sub-conductive wire 1131 and the fourth sub-conductive wire 1132.

[0061] In this embodiment, the second slideway 1133 is formed in the third segment 113 of the first coil turn, thereby facilitating the active connection between the third segment 113 of the first coil turn and the adjacent coil turn outside the first coil turn.

[0062] Optionally, the antenna further includes a driving component, wherein the driving component is connected to the second wiring component 200, and the driving component is used to drive the second wiring component 200 to move between the first position and the second position.

[0063] Among them, the driving component can be a common telescopic component, for example, it can be a telescopic motor, an electric telescopic rod, etc., so that the driving component performs telescopic movement, thereby driving the second wiring component 200 to move back and forth between the first position and the second position.

In addition, the features described with reference to certain examples may be combined in other examples.

[0067] Through the description of the above implementation methods, those skilled in the art can clearly understand that the above-mentioned embodiment methods can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a magnetic disk, or an optical disk), and includes a number of instructions for a terminal (which can be a mobile phone, a computer, a server, an air conditioner, or a network device, etc.) to execute the methods described in each embodiment of the present application.
