[0033] To make the purpose, technical solutions and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the drawings.

[0034] It should be noted that the embodiments in the present disclosure and the features in the embodiments can be combined with each other without conflict. The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0035] An embodiment of the present disclosure provides a wireless charging assembly, as shown in Figure 1 The wireless charging assembly includes a coil assembly 1, a protective sleeve 2 and a metal sheet 3. As shown in Figure 2 The protective sleeve 2 includes a main body part 21 and a connecting part 22 connected with each other, the main body part 21 is fixed to the outside of the coil assembly 1, and the connecting part 22 is used for fixedly connecting with the middle frame of the electronic device. The first part 31 of the metal sheet 3 is fixedly connected with the main body part 21, and the second part 32 is fixedly connected with the connecting part 22.

[0036] In the embodiment of the present disclosure, by arranging the metal sheet 3, the structure of the protective sleeve 2 can be reinforced at the transition position of the main body part 21 and the connecting part 22, so that when the electronic device is subjected to external impact, the possibility of the protective sleeve 2 being torn at the transition position of the main body part 21 and the connecting part 22 due to the shaking of the main body part 21 can be reduced.

[0037] As shown in Figure 1As shown, the coil assembly 1 includes a wireless charging coil 11 and a signal wire 12 electrically connected to each other. The signal wire 12 is fixedly connected to the main body part 21 and partially located on the first side of the connecting part 22. The part is used to be fixedly connected to the middle frame, so as to strengthen the structure of the protective sleeve 2 on the first side of the connecting part 22, thereby reducing the possibility of tearing the transition position between the first side of the connecting part 22 and the main body part 21.

[0038] Optionally, the wireless charging coil 11 is made of copper wire. Copper is a metal material with extremely low resistivity, and its electrical conductivity is only second to silver. Copper has the advantages of low cost and good ductility. In addition, copper has good heat dissipation effect, which can effectively disperse the heat generated during charging and avoid overheating.

[0039] As shown in Figure 1 , the wireless charging assembly further includes a connector assembly 4. The connector assembly 4 includes a first connector 41 fixed on the side of the signal wire 12 away from the wireless charging coil 11. The first connector 41 is used to be connected to the circuit board of the electronic device, so as to realize the transmission of electric energy between the wireless charging assembly and the circuit board.

[0040] In some embodiments, as shown in Figure 1 , Figure 2 , the second part 32 of the metal sheet 3 is located on the second side of the connecting part 22, and the second side is opposite to the first side.

[0041] In combination with the above, the signal wire 12 can strengthen the structure of the protective sleeve 2 on the first side of the connecting part 22, thereby reducing the possibility of tearing the transition position between the first side of the connecting part 22 and the main body part 21. At the same time, by arranging the second part 32 of the metal sheet 3 on the second side of the connecting part 22, the structure of the protective sleeve 2 on the second side of the connecting part 22 can be strengthened, thereby reducing the possibility of tearing the transition position between the second side of the connecting part 22 and the main body part 21.

[0042] Therefore, in the embodiments of the present disclosure, by cooperation of the signal wire 12 and the metal sheet 3, the possibility of tearing the transition position between the connecting part 22 and the main body part 21 can be reduced as a whole in the case of using a metal sheet 3 with a smaller size. In this way, on the one hand, the material cost of the metal sheet 3 can be reduced, and on the other hand, the weight of the metal sheet 3 can be reduced, thereby reducing the weight of the wireless charging assembly, and further reducing the weight of the electronic device.

[0043] In some embodiments, as shown in Figure 2 , the protective sleeve 2 further includes a transition part 23 connecting the main body part 21 and the connecting part 22. The edge of the transition part 23 close to the second side forms an obtuse angle with the edge of the connecting part 22 and the edge of the main body part 21.

[0044] In combination, the signal line 12 can strengthen the structure of the protective sleeve 2 on the first side. In the related art, on the second side, the edge of the transition portion 23 between the connecting portion 22 and the main body portion 21 forms a right angle with one of the edge of the connecting portion 22 and the edge of the main body portion 21, which causes stress concentration at this position. When an external force is applied, the stress will accumulate at the right angle edge, and tearing will occur when the stress exceeds the bearing limit of the material.

[0045] In comparison, in the embodiment of the present disclosure, on the second side, the edge of the transition portion 23 forms an obtuse angle with the edge of the connecting portion 22 and the edge of the main body portion 21, which can reduce the transition between the edge of the connecting portion 22 and the edge of the main body portion 21, and further reduce the stress concentration of the edge of the connecting portion 22 and the edge of the main body portion 21, so as to reduce the possibility of tearing of the transition portion 23 between the connecting portion 22 and the main body portion 21.

[0046] Optionally, the edge of the transition portion 23 forms an angle of 120°-150° with the edge of the connecting portion 22, and the edge of the transition portion 23 forms an angle of 120°-150° with the edge of the main body portion 21. For example, the edge of the transition portion 23 forms an angle of 135° with the edge of the connecting portion 22 and the edge of the main body portion 21.

[0047] In some embodiments, as shown in Figure 2 The third portion 33 of the metal sheet 3 is fixedly connected to the position of the transition portion 23 close to the second side.

[0048] In this way, the position of the transition portion 23 close to the second side can be further structurally strengthened by the metal sheet 3, so as to further improve the structural strength of the transition portion 23 on the second side, and further reduce the possibility of tearing of the transition portion 23.

[0049] In some embodiments, the width of the metal sheet 3 is 1mm-2mm.

[0050] If the width of the metal sheet 3 is less than 1mm, the width of the metal sheet 3 is too small, which will result in low structural strength of the metal sheet 3 itself, and thus limit the structural strengthening effect of the metal sheet 3 on the protective sleeve 2; if the width of the metal sheet 3 is greater than 2mm, the width of the metal sheet 3 is too large, and the increase in size also limits the structural strengthening effect on the edge of the protective sleeve 2, which will result in waste of material of the metal sheet 3 and increase the weight of the wireless charging coil 11, which is not conducive to the lightweight design of the electronic device. By setting the width of the metal sheet 3 to 1mm-2mm, the structural strengthening effect of the metal sheet 3 on the protective sleeve 2 can be ensured, and the situation of excessive size of the metal sheet 3 leading to material waste can be prevented.

[0051] Optionally, the width of the metal sheet 3 can be, for example but not limited to, 1.3 mm, 1.5 mm, 1.7 mm or 1.9 mm.

[0052] In some embodiments, as shown in Figure 1 The coil assembly 1 further includes an NFC (Near Field Communication) coil 13 fixed in the main body portion 21 and surrounding the wireless charging coil 11, and electrically connected with the signal line 12.

[0053] In this way, the embodiments of the present disclosure can realize the wireless charging function and the NFC function at the same time through one wireless charging assembly. The integrated design enables the NFC coil 13 and the wireless charging coil 11 to share the same space, thereby reducing the occupied space inside the electronic device and improving the utilization rate of the internal space of the electronic device.

[0054] As shown in Figure 1 The connector assembly 4 includes a second connector 42 fixed on the side of the signal line 12 away from the NFC coil 13, which is used to connect with the circuit board of the electronic device to realize the NFC signal transmission between the wireless charging assembly and the circuit board.

[0055] In some embodiments, the metal sheet 3 is located in the protective sleeve 2.

[0056] In this way, the two sides of the protective sleeve 2 can be structurally reinforced at the same time by the metal sheet 3, so that the structural reinforcement of the protective sleeve 2 by the metal sheet 3 can be further improved to further reduce the possibility of tearing at the transition position between the first side of the connecting portion 22 and the main body portion 21.

[0057] In some embodiments, the thickness of the metal sheet 3 is 0.1-0.4 mm.

[0058] If the thickness of the metal sheet 3 is less than 0.1 mm, the thickness of the metal sheet 3 is too small, which will result in a relatively low structural strength of the metal sheet 3, thereby limiting the structural reinforcement of the protective sleeve 2 by the metal sheet 3. If the thickness of the metal sheet 3 is greater than 0.4 mm, the thickness of the metal sheet 3 is too large, thereby occupying too much space. By setting the thickness of the metal sheet 3 to be 0.1-0.4 mm, the structural reinforcement of the protective sleeve 2 by the metal sheet 3 can be ensured, and the metal sheet 3 can also be prevented from occupying too much space due to its large size.

[0059] In some embodiments, the main body portion 21 has a limiting structure 211 located on the side of the main body portion 21 away from the connecting portion 22, and used to be fixedly connected with the middle frame.

[0060] Thus, by limiting structure 211, the main body 21 is fixed on the side away from the connecting portion 22, which can reduce the amplitude of the main body 21 shaking, thereby further reducing the possibility of the protective sleeve 2 being torn at the transition position of the main body 21 and the connecting portion 22 due to the shaking of the main body 21.

[0061] In some embodiments, the metal sheet 3 is a copper sheet.

[0062] In some embodiments, the copper is a better electromagnetic shielding material, and the metal sheet 3 is made of copper, which can reduce the interference of the metal sheet 3 on the NFC signal.

[0063] In some embodiments, as shown in Figure 3 The wireless charging assembly further includes a diaphragm assembly 5 fixedly connected with the protective sleeve 2 to improve the structural strength of the protective sleeve 2.

[0064] The diaphragm assembly 5 includes a first diaphragm 51 fixed to the outside of the main body 21 and partially protruding from the main body 21, and the protruding part has a positioning hole 511 for positioning the installation of the coil assembly 1.

[0065] Further, the diaphragm assembly 5 further includes a second diaphragm 52 embedded in the connecting portion 22 to enhance the structural strength of the connecting portion 22.

[0066] In the embodiments of the present disclosure, the coil assembly 1, the protective sleeve 2 and the metal sheet 3 are a whole FPC (Flexible Printed Circuit, flexible circuit board) structure, the wireless charging coil 11 and the NFC coil 13 are wound by copper wires in the FPC structure, and the metal sheet 3 is laser-engraved and formed by copper material in the FPC structure.

[0067] Thus, the assembly complexity between the wireless charging coil 11, the NFC coil 13 and the connecting wire can be further reduced to improve the efficiency of the electronic device assembly.

[0068] The FPC structure is a multi-layer structure, and the internal layers of the FPC have through holes for connecting the wires. The through holes between the internal layers of the FPC are located on the side of the transition portion 23 close to the main body 21, or on the main body 21, to prevent the through holes from reducing the structural strength of the FPC. Thus, the overall structural strength of the FPC can be ensured.

[0069] Based on the same idea, the embodiments of the present disclosure also provide an electronic device, which includes the wireless charging assembly provided above.
