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

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

In some embodiments of the present application, the antenna assembly 30 includes a plurality of antenna coils 31, and 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 coil 31 can increase the spatial arrangement of the antenna assembly 30.

Alternatively, the plurality of antenna coils 31 have the same length, that is, 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 of the sleeve 21 and extends and forms along the telescopic direction of the sleeve 21, so that the spatial arrangement of the antenna assembly 30 can be enlarged, the induction area of the antenna assembly 30 is increased, the magnetic field flux is increased, and the communication efficiency is improved.

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

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 two by two to form a closed loop path. In addition, this application can also be through adjusting the quantity of antenna coil 31 for antenna module 30 has different coil density and different inductance values, thereby according to actual need, with the communication function module of different working frequency bands of adaptation.

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

In some alternative embodiments, in the case where two sleeves 21 connected to each other are in the 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 sleeves 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 sleeves 21 are overlapped. It can be understood 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 are overlapped, and the at least two antenna coils 31 are approximately in the same horizontal plane, so as to form a multi-layer antenna coil 31 structure with a high coil density. When the external device 200 is close, the magnetic field flux of the multi-layer antenna coil 31 is increased 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. When the at least two sleeves 21 are moved relatively, that is, when the at least two sleeves 21 are in the 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. In this case, it is not necessary to align the external device 200 with the antenna coil 31 completely, and the magnetic induction line of the external device 200 can penetrate the antenna coil 31, thereby 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 expansion of the two interconnected sleeves 21.

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

In the embodiment of the present application, in the telescopic direction of the sleeve 21, the moving distance of the sleeve 21 may be controlled 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 at this position, 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 the sleeve 21 corresponding thereto, so that the overall coil density can be increased and the wireless communication function can be enhanced.

Fig. 5 is a schematic structural diagram of an antenna assembly of the electronic device according to the embodiment of the present application.

In some alternative embodiments, as shown in fig. 5, in the case that at least two sleeves 21 connected with each other are in the contracted state, the length of each antenna coil 31 is smaller than the length of the 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 on the premise of improving the wireless communication effect between the electronic device 100 and the external device 200, which is convenient for realizing the lightness and thinness of the electronic device 100.

In some alternative embodiments, as shown in fig. 1, 4 and 5, the projections of the antenna coils 31 on the central axis of the sleeve 21 are not coincident.

In the embodiment of the present application, the projections of the antenna coils 31 on the central axis of the sleeve 21 are not overlapped, and it can be understood that the projections of the two antenna coils 31 on the central axis of the sleeve 21 are not overlapped when at least two sleeves 21 are in the contracted state or when 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 antenna coils 31 provided on the at least two sleeves 21 in the telescopic direction 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 the contracted state, the lengths of the antenna coils 31 provided on the at least two sleeves 21 in the telescopic direction of the sleeves 21 are different.

Alternatively, in the case where the two sleeves 21 connected to each other are in the contracted state, the total length of the at least two antenna coils 31 is equal to the length of the sleeves 21, and the lengths of the sleeves 21 are all 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 the antenna coils 31 on the central axis of the sleeve 21 are not coincident. Alternatively, the projection of each antenna coil on the central axis of the sleeve 21 may be continuous or discontinuous. So set up, can reduce the winding density of antenna coil 31, be favorable to realizing to a certain extent that electronic equipment 100 is frivolous, mainly because the increase of antenna coil 31 density often needs reserve more spaces for antenna module 30 on casing 10, will be unfavorable for realizing that electronic equipment 100 is frivolous like this. Furthermore, the projections of the antenna coils 31 on the central axis of the sleeve 21 do not overlap, and when at least two sleeves 21 are in the contracted state, at least two antenna coils 31 can assume a three-dimensional shape, and the effect of wireless communication between the electronic apparatus 100 and the external apparatus 200 can be improved even if the sleeves 21 do not move.

In some alternative embodiments, as shown in fig. 1 and 4, the radial dimensions of at least two sleeves 21 are sequentially increased or sequentially decreased in a case where the two sleeves 21 connected to each other are in a contracted state.

In these alternative embodiments, the radial dimensions of at least two sleeves 21 are sequentially increased or sequentially decreased, and it can be understood that, in the retracted state of the sleeve assembly 20, at least two sleeves 21 are sleeved layer by layer to collect the other sleeves 21 in one sleeve 21, so as to reduce the space occupancy of the electronic device 100 to a certain extent, and make the electronic device 100 lighter, thinner and more miniaturized. Even if the sleeve assembly 20 is disposed on the outer surface of the electronic apparatus 100, the overall appearance of the electronic apparatus 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, the at least two first magnetic members 40 are disposed corresponding to the surfaces of the 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. Thus, the antenna coil 31 can be sleeved on the first magnetic element 40. In addition, the first magnetic member 40 may also be a rectangular magnetic member or a circular magnetic member, or the like.

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

Optionally, the first magnetic member 40 is ferrite. The ferrite can absorb the electromagnetic wave energy projected to the surface of the ferrite and the electromagnetic radiation leaked by other devices, thereby achieving the purpose of eliminating the electromagnetic interference.

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, because the magnetic permeability of the first magnetic member 40 is high, it can be used to focus the magnetic field flux, so as to enhance the magnetic field strength of the antenna coil 31, and also effectively increase the communication induction distance, and to some extent, improve the effect of wireless communication between the electronic device 100 and the external device 200. In addition, the antenna coil 31 is sleeved on the first magnetic member 40, and the antenna coil 31 can protect the first magnetic member 40.

Moreover, the second magnetic member 50 is fixedly disposed at the end of the sleeve assembly 20, so that the effect of improving wireless communication is achieved, the process complexity is reduced, 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, and the protective layer 32 covers the antenna coil 31.

Optionally, the protective layer 32 is an electroplated layer, a paint layer, a silk-screen printing ink layer, and the like, so that the protective layer 32 well protects the antenna coil 31 and prevents the antenna coil 31 from being exposed.

In these alternative embodiments, the protective layer 32 covers the antenna coil 31, so that the antenna coil 31 is folded in the protective layer 32, which can be understood that the antenna coil 31 is disposed in the accommodating space of the protective layer 32, and in the process of moving the sleeve 21, the antenna coil does not separate from the accommodating space and shake or deform back and forth, so as to ensure that the magnetic field strength is stable.
