From another perspective, the first positioning mechanism is used for positioning the non-terminal device, so that the wireless transmitting end and the wireless receiving end are aligned. By "aligning the wireless receiving end with the wireless transmitting end" is understood that the deviation of the axis of the wireless transmitting end from the axis of the wireless receiving end is within a small range, for example, the deviation is 10% of the radial dimension of the wireless transmitting end. According to the invention, the wireless transmitting assembly is positioned by the first positioning mechanism, so that the alignment of the wireless receiving end and the wireless transmitting end is realized, and further, most of the magnetic field generated by the wireless transmitting end can pass through the wireless receiving end, and the energy of the part of the magnetic field passing through the wireless receiving end can be converted into electric energy, so that the loss of the magnetic field energy caused by the misalignment of the wireless receiving end and the wireless transmitting end is avoided, and the wireless charging efficiency of the terminal equipment is improved. And the energy loss caused by the fact that the part of the magnetic field which does not pass through the wireless receiving end is relatively weak due to the fact that the part of the magnetic field is far away from the center of the wireless transmitting end.
The terminal device can be an electronic device including a battery, such as a mobile phone, a tablet computer and a smart watch. Referring to fig. 1 and 2, in this embodiment, the terminal device 1 is a mobile phone, and includes a housing 10, a camera assembly 11, a first positioning mechanism 13, a wireless receiving end 12 disposed in a space surrounded by the housing 10, a battery assembly, a processor assembly, a memory assembly, and an antenna assembly, which are not shown in the drawings.

Preferably, the protrusion 221 has a certain elasticity and a size slightly larger than the groove 131, so as to ensure that there is enough holding force between the protrusion 221 and the groove 131, so that the terminal device 1 stably holds the wireless transmission component 2. It is easy to understand that the position of the protrusion 221 corresponds to the position of the groove 131, and the protrusion 221 and the groove 131 cooperate to ensure that the wireless transmitting end 12 is coaxial with the wireless receiving end 21. Coaxial can be understood as a preferred alignment of the wireless transmitting end 12 and the wireless receiving end 21, and the efficiency of wireless charging is higher. Of course, some deviation from coaxial alignment may also be considered as a way of alignment.
The terminal device further comprises a magnetically conductive element 15, the magnetically conductive element 15 being made of a magnetically conductive material. The magnetic conductive element 15 is disposed between the housing 10 and the wireless receiving end 12. The magnetic conducting element 15 covers the wireless receiving end 12, the radial size of the magnetic conducting element 15 is larger than that of the wireless receiving end 12 and that of the wireless transmitting end 21, and a magnetic field generated by the wireless transmitting end 21 radiates to the wireless receiving end 12 along the magnetic conducting element 15 with high magnetic conductivity, so that energy loss is reduced, and the wireless charging efficiency is further improved.
Fig. 3 and 4 show the assembled structure of the terminal device 1 and the wireless transmission component 2, wherein the wireless transmission component 2 is accommodated in the recess 102, and preferably, the outer surface of the wireless transmission component 2 is flush with the first surface 101. Compared with the prior art that the mobile phone is directly placed on the wireless transmitting assembly, the invention has the advantages that the alignment precision of the wireless receiving end 12 and the wireless transmitting end 21 is higher, most of the magnetic field generated by the wireless transmitting end can pass through the wireless receiving end, the energy loss is reduced, and the wireless charging efficiency of the terminal equipment is improved. Meanwhile, when wireless charging is performed, the user can directly hold the terminal device 1 and use the terminal device, the wireless transmitting component is also taken up at the same time, and the current is transmitted to the wireless transmitting terminal 12 through the cable component.
In one embodiment, the first positioning mechanism 13 includes a plurality of protrusions integrally formed with the housing, and the second positioning mechanism 22 includes a plurality of grooves engaged with the protrusions, and the protrusions are disposed in the recessed portion 102 and do not protrude from the first surface 101, so as not to affect the normal use of the terminal device.

In other words, the first positioning mechanism 13 attracts the second positioning mechanism 22 by magnetic force, thereby attracting the entire wireless transmission assembly 2. Due to the action of magnetic force, the first positioning mechanism 13 is matched with the second positioning structure 22 to realize axial positioning and radial positioning of the wireless transmitting assembly 2, and the alignment accuracy of the wireless receiving end 12 and the wireless transmitting end 21 is ensured. In addition, the ring magnet of the first positioning mechanism 13 surrounds the wireless receiving end 12, so that the first positioning mechanism 13 and the wireless receiving end 12 are prevented from being arranged along the thickness direction of the terminal device 1, and the thickness of the terminal device 1 is reduced. On the other hand, the first positioning mechanism 13 is provided inside the housing 10, and does not spoil the appearance of the entire terminal device. It should be noted that the ring magnet is used as a permanent magnet, and the generated magnetic field is a constant magnetic field, so that the alternating magnetic field for realizing the electric energy transmission is not influenced.
