At present, an antenna coil of an electronic device and an external device realize wireless communication, and the antenna coil of the electronic device is mainly aligned with the end face of the antenna coil of the external device, wherein a magnetic induction wire in one antenna coil can penetrate into the interior of the other antenna coil, so that wireless communication is realized. However, when the antenna coil of the external device and the antenna coil of the electronic device have differences in shape and size, the complete alignment cannot be ensured, and when the antenna coil of the external device and the antenna coil of the electronic device are dislocated or offset, the magnetic field flux becomes smaller, the induced voltage becomes smaller, and the problem of failure in establishing the wireless communication connection may be caused.

The electronic device 100 provided in the embodiment of the application, through setting up sleeve subassembly 20 and antenna assembly 30, antenna assembly 30 sets up on sleeve subassembly 20, and at sleeve subassembly 20 flexible in-process takes place, sleeve subassembly 20 can drive antenna coil 31 motion, can increase antenna coil 31's spatial distribution for magnetic field flux can pass antenna coil 31 from a plurality of angles, thereby realizes three-dimensional communication function, improves communication efficiency simultaneously, and the user uses more conveniently. Furthermore, the antenna assembly 30 includes at least two antenna coils 32 connected in pairs, and a multi-layered antenna coil 31 structure may be formed such that the density of the antenna assembly 30 is increased, and the magnetic field flux of the antenna assembly 30 is improved to some extent, to enhance the communication function. In addition, the matching arrangement of the sleeve assembly 20 and the antenna assembly 30 simplifies the structure of the electronic device 100, reduces the space size of the electronic device 100, and is beneficial to miniaturization of the electronic device 100.

In some alternative embodiments, as shown in fig. 1 and 4, the antenna coil 31 is disposed on a side surface of the sleeve 21 and is formed to extend in the expansion and contraction direction of the sleeve 21.

In some embodiments of the present application, the antenna coil 31 is embedded in the inner side surface of the sleeve 21, or the antenna coil 31 may be embedded in the outer side surface of the sleeve 21.

In some embodiments of the present application, the antenna assembly 30 includes a plurality of antenna coils 31, where the plurality of antenna coils 31 may be arranged at intervals along the central axis direction of the sleeve 21, or the plurality of antenna coils 31 may be arranged side by side along the central axis direction of the sleeve 21. The above arrangement of the antenna coils 31 can increase the spatial arrangement of the antenna assembly 30.

Alternatively, the lengths of the plurality of antenna coils 31 are the same, i.e., the plurality of antenna coils 31 have the same number of turns, which is convenient for industrial manufacturing.

In these alternative embodiments, the antenna coil 31 is disposed on the side surface of the sleeve 21 and is formed by extending along the telescopic direction of the sleeve 21, so that the spatial arrangement of the antenna assembly 30 can be enlarged, and the induction area of the antenna assembly 30 can be increased, thereby improving the magnetic field flux and further improving the communication efficiency.

In some alternative embodiments, as shown in fig. 1 and 4, at least two antenna coils 31 are provided corresponding to at least two sleeves 21, and each antenna coil 31 is provided to its corresponding sleeve 21.

In the embodiment of the present application, the antenna assembly 30 includes at least two antenna coils 31, and the at least two antenna coils 31 are connected in pairs to form a closed loop path. In addition, the number of the antenna coils 31 can be adjusted, so that the antenna assembly 30 has different coil densities and different inductance values, and the communication function modules with different working frequency bands can be adapted according to actual needs.

In these alternative embodiments, the antenna assembly 30 includes at least two antenna coils 31, and at least two antenna coils 31 are disposed on different sleeves 21, it will be understood that each antenna coil 31 is disposed on a different sleeve 21, so that when two sleeves 21 connected to each other are telescopic, the sleeves 21 can drive the antenna coils 31 to move, so as to further expand the spatial arrangement of the antenna assembly 30 and increase the sensing area of the antenna assembly 30.

In some alternative embodiments, in the case where the two sleeves 21 connected to each other are in a contracted state, the length of each antenna coil 31 is equal to the length of the sleeve 21 corresponding thereto in the telescopic direction of the sleeve 21.

In some embodiments of the present application, along the telescopic direction of the sleeve 21, the length of each antenna coil 31 is equal to the length of the corresponding sleeve 21, and in the case that the lengths of the sleeves 21 are equal, the lengths of the antenna coils 31 are also equal, so that when the sleeves 21 are in the contracted state, the projections of the antenna coils 31 on the central axis of the sleeve 21 overlap. It will be appreciated that in the contracted state of the sleeve assembly 20, the projections of the at least two antenna coils 31 disposed on the at least two sleeves 21 on the central axis of the sleeve 21 coincide, the at least two antenna coils 31 being approximately in the same horizontal plane, forming a multi-layered antenna coil 31 structure with a greater coil density. When the external device 200 is close, the magnetic field flux of the multi-layer antenna coil 31 is enhanced as compared to the single-layer antenna coil 31 (only one antenna coil 31), thereby improving the effect of the electronic device 100 based on wireless communication between the antenna coil 31 and the external device 200. The at least two sleeves 21 are moved relatively, i.e. when the at least two sleeves 21 are in an extended state, the three-dimensional space formed by the at least two antenna coils 31 approximates a three-dimensional annular structure, and the at least two antenna coils 31 are uniformly distributed in the three-dimensional space. At this time, the external device 200 magnetic induction line can penetrate into the antenna coil 31 without the need of completely aligning the external device 200 with the antenna coil 31, further improving the effect of wireless communication between the electronic device 100 and the external device 200. Moreover, the communication posture and position of the wireless communication can be more flexible.

Illustratively, the three-dimensional space formed by the at least two antenna coils 31 gradually increases during the extension of the two sleeves 21 that are connected to each other.

Illustratively, the three-dimensional space formed by the at least two antenna coils 31 gradually decreases during the contraction of the two sleeves 21 that are connected to each other.

In the embodiment of the present application, the moving distance of the sleeve 21 may be controlled in the telescopic direction of the sleeve 21 to change the size of the three-dimensional space formed by the antenna coil 31. Moreover, during the movement of the sleeve 21, the wireless connection effect between the electronic device 100 and the external device 200 may change, and when the electronic device 100 and the external device 200 have a relatively good wireless connection effect, the sleeve 21 may be controlled to stop, thereby effectively ensuring efficient wireless communication between the electronic device 100 and the external device 200.

In these alternative embodiments, the length of each antenna coil 31 is equal to the length of its corresponding sleeve 21, and this arrangement can increase the total coil density and enhance the wireless communication function.

Referring to fig. 5, a schematic structural diagram of an antenna assembly of an electronic device according to an embodiment of the present application is shown.

In some alternative embodiments, as shown in fig. 5, in the case where at least two sleeves 21 connected to each other are in a contracted state, the length of each antenna coil 31 is smaller than the length of its corresponding sleeve 21 in the telescopic direction of the sleeve 21.

In these alternative embodiments, the length of each antenna coil 31 is smaller than the length of the corresponding sleeve 21, so that the winding density of the antenna coil 31 can be reduced under the premise of satisfying the improvement of the wireless communication effect between the electronic device 100 and the external device 200, and the electronic device 100 is easy to be thinned.

In some alternative embodiments, as shown in fig. 1, 4 and 5, the projections of each antenna coil 31 on the central axis of the sleeve 21 do not coincide.

In the embodiment of the present application, the projections of each antenna coil 31 on the central axis of the sleeve 21 do not overlap, which is understood to mean that the projections of the two antenna coils 31 on the central axis of the sleeve 21 do not overlap, both when the at least two sleeves 21 are in the contracted state and when the at least two sleeves 21 are in the extended state.

In some embodiments of the present application, in a case where the two sleeves 21 connected to each other are in a contracted state, the lengths of the respective antenna coils 31 provided on the at least two sleeves 21 in the expansion and contraction directions of the sleeves 21 are equal.

In other embodiments of the present application, in a case where the two sleeves 21 connected to each other are in a contracted state, the lengths of the respective antenna coils 31 provided on the at least two sleeves 21 in the expansion and contraction directions of the sleeves 21 are not equal.

Alternatively, in the case where the two sleeves 21 connected to each other are in the contracted state, the total length of at least two antenna coils 31 is equal to the length of the sleeve 21, and the lengths of the respective sleeves 21 are equal. The arrangement is such that the antenna assembly 30 is reasonably arranged on the sleeve assembly 20, and the magnetic field path of the antenna assembly 30 is enhanced in a limited space.

In these alternative embodiments, the projections of each antenna coil 31 on the central axis of the sleeve 21 do not coincide. Alternatively, the projection of each antenna coil onto the central axis of the sleeve 21 may be continuous or intermittent. By the arrangement, the winding density of the antenna coil 31 can be reduced, which is beneficial to the realization of the light and thin electronic device 100 to a certain extent, mainly because of the increase of the density of the antenna coil 31, more space is often required to be reserved for the antenna assembly 30 on the housing 10, and thus the realization of the light and thin electronic device 100 is not beneficial. Further, the projections of the respective antenna coils 31 on the central axis of the sleeve 21 do not overlap, and when at least two of the sleeves 21 are in the contracted state, at least two of the antenna coils 31 can take on a three-dimensional shape, and even if the sleeves 21 do not move, the effect of wireless communication between the electronic apparatus 100 and the external apparatus 200 can be improved.

In some alternative embodiments, as shown in fig. 1 and 4, with the two sleeves 21 connected to each other in a contracted state, the radial dimensions of at least two sleeves 21 increase or decrease sequentially.

In these alternative embodiments, the radial dimensions of at least two sleeves 21 increase or decrease sequentially, which means that in the contracted state of the sleeve assembly 20, at least two sleeves 21 are sleeved layer by layer, so that other sleeves 21 are all folded in one sleeve 21, which reduces the space occupation rate of the electronic device 100 to a certain extent, and makes the electronic device 100 lighter, thinner and miniaturized. Even if the sleeve assembly 20 is provided on the outer surface of the electronic device 100, the overall appearance of the electronic device 100 is less affected.

In some alternative embodiments, as shown in fig. 4 and 5, the electronic device 100 further includes at least two first magnetic members 40, at least two first magnetic members 40 are disposed corresponding to surfaces of at least two sleeves 21, and the antenna coil 31 disposed on each sleeve 21 is disposed corresponding to the first magnetic member 40 of the sleeve 21.

In some embodiments of the present application, the first magnetic member 40 is a ring-shaped magnetic member having the same structure as the antenna coil 31. So arranged, the antenna coil 31 can be sleeved on the first magnetic member 40. In addition, the first magnetic member 40 may be a rectangular magnetic member, a circular magnetic member, or the like.

In some embodiments of the present application, the antenna coil 31 and the corresponding first magnetic element 40 are stacked, and along the axial direction of the sleeve assembly 20, the length of the antenna coil 31 is equal to the length of the corresponding first magnetic element 40, so that the first magnetic element 40 does not protrude from the antenna coil 31, and does not occupy additional space, thereby reducing the occupation of the first magnetic element 40 in the internal space of the electronic device 100, and also not affecting the arrangement of other components in the electronic device 100.

Alternatively, the first magnetic member 40 is ferrite. The ferrite can absorb electromagnetic wave energy projected to the surface of the ferrite and electromagnetic radiation leaked by other devices, so that the aim of eliminating electromagnetic interference can be achieved.

In these alternative embodiments, the first magnetic member 40 is disposed on the sleeve assembly 20, and the antenna coil 31 is disposed around the first magnetic member 40, so that the magnetic permeability of the first magnetic member 40 is high, and the first magnetic member can be used to bunch the magnetic field flux, so as to enhance the magnetic field strength of the antenna coil 31, and further effectively increase the communication induction distance, and improve the effect of wireless communication between the electronic device 100 and the external device 200 to a certain extent. In addition, the antenna coil 31 is sleeved on the first magnetic element 40, and the antenna coil 31 can protect the first magnetic element 40.

Alternatively, the second magnetic member 50 is ferrite and is identical to the first magnetic member 40.

In these alternative embodiments, the end of the sleeve assembly 20 near the housing 10 is provided with the second magnetic member 50, and the second magnetic member 50 can be used to bunch the magnetic field flux, enhance the magnetic field strength of the antenna coil 31, and also effectively increase the communication induction distance, and improve the effect of wireless communication between the electronic device 100 and the external device 200 to some extent. Moreover, the second magnetic member 50 is fixedly disposed at the end of the sleeve assembly 20, so that the process complexity can be reduced while the wireless communication effect is improved, and the second magnetic member 50 disposed at the end of the sleeve assembly 20 is easier to install and operate.

In some alternative embodiments, as shown in fig. 5 and 7, the antenna assembly 30 further includes a protective layer 32, where the protective layer 32 covers the antenna coil 31.

Optionally, the protective layer 32 is a plating layer, a paint layer, a screen printing ink layer, and the like, so that the protective layer 32 well protects the antenna coil 31 from exposure of the antenna coil 31.

In these alternative embodiments, the protection layer 32 is wrapped on the antenna coil 31, so that the antenna coil 31 is folded in the protection layer 32, and it can be understood that the antenna coil 31 is disposed in the accommodating space of the protection layer 32, and does not deviate from the accommodating space to shake or deform during the movement of the sleeve 21, so as to ensure the stable magnetic field strength.

In some alternative embodiments, sleeve assembly 20 is movably coupled to housing 10.

In the embodiment of the present application, the sleeve assembly 20 is movably connected to the housing 10, it is understood that the sleeve assembly 20 disposed on the housing 10 is rotatably connected to the housing 10, or the sleeve assembly 20 disposed on the housing 10 is hingedly connected to the housing 10, or the like.

In these alternative embodiments, the sleeve assembly 20 is movably connected with the housing 10 to adjust the positional relationship between the sleeve assembly 20 and the housing 10, so as to adjust the spatial angle of the antenna assembly 30, and when the antenna coil 31 of the external device 200 does not correspond to the position of the antenna coil 31 of the electronic device 100, or the antenna coil 31 of the external device 200 and the antenna coil 31 of the electronic device 100 have differences in shape and size, the spatial angle of the antenna assembly 30 can be adjusted, so that the magnetic field flux achieved between the antenna coil 31 of the external device 200 and the antenna coil 31 of the electronic device 100 is maximized, and in addition, the arrangement can also realize a multi-angle and multi-azimuth communication function.

In some alternative embodiments, the electronic device 100 further includes an external assembly 60, the external assembly 60 being disposed on a side of the sleeve assembly 20 facing away from the housing 10, the external assembly 60 being coupled to the sleeve assembly 20.
