The wireless charging receiver realizes wireless conduction of electric energy by receiving electromagnetic waves transmitted by the wireless charging transmitter, and further wirelessly charges equipment (such as a vehicle or an unmanned vehicle).

In the creation process of implementing the technical solution of the present application, the inventor finds that, in the process of performing wireless charging, the electromagnetic wave transmitted by the wireless charging transmitter is difficult to be completely received by the wireless charging receiver, so that a stray magnetic field generated by the wireless charging transmitter also exists around the wireless charging receiver, which causes that components around the wireless charging receiver (for example, components on a device where the wireless charging receiver is located, when the wireless charging receiver is installed on a vehicle, the components may be a controller, a frame, a part, and the like, but are not limited thereto) are susceptible to the magnetic field, and the components around the wireless charging receiver may also generate electromagnetic interference to affect the wireless charging efficiency, especially metal components.

To solve the above problems, the inventors have tried the following solutions: the electromagnetic shielding member adopting a plate-shaped structure or a sheet-shaped structure is installed on the wireless charging receiver to electromagnetically shield components around the wireless charging receiver. However, the inventor found that although the electromagnetic shielding member with the plate-shaped structure or the sheet-shaped structure can achieve electromagnetic shielding, the electromagnetic shielding member with the plate-shaped structure or the sheet-shaped structure has a protruded corner, and is relatively sharp, and is easily damaged to external objects (for example, when the wireless charging receiver 20 is disposed at the bottom of a vehicle, the electromagnetic shielding member 01 with the plate-shaped structure or the sheet-shaped structure is suspended at the bottom of the vehicle, has a certain killing property, and is easily damaged to living things or other objects in the surrounding environment, as shown in fig. 1); and the wireless charging receiver is exposed to the outside and is easily damaged by the influence of external objects (for example, when the wireless charging receiver is arranged at the bottom of the vehicle, namely, the wireless charging receiver is exposed between the chassis of the vehicle and the ground, the wireless charging receiver is easily corroded by silt, and is easily collided by an obstacle higher than the ground, so that the service life is seriously influenced).

Based on this, in order to improve the technical problems that the components around the wireless charging receiver in the related art are easily interfered by the magnetic field and easily affect the wireless charging efficiency, so as to achieve electromagnetic shielding under the conditions of improving the protection effect on the wireless charging receiver and reducing the influence on the outside, the inventor proposes the following scheme.

Referring to fig. 2 to 5, an electromagnetic shielding case 10 for electromagnetically shielding components around a wireless charging receiver is provided in an embodiment of the present application, and a wireless charging receiver 20 is exemplarily shown in fig. 5 and 7. The electromagnetic shield 10 has a first end 11 and a second end 12 disposed opposite to each other, and an outer sidewall 13 located between the first end 11 and the second end 12. The cross-sectional perimeter of the end of the outer sidewall 13 near the second end 12 is smaller than the cross-sectional perimeter of the other end near the first end 11. The electromagnetic shielding case 10 has an accommodating space 101 for accommodating the wireless charging receiver 20 therein, the second end 12 is opened with an opening 102 communicated with the accommodating space 101, and the opening 102 is used for the wireless charging receiver 20 to receive electromagnetic waves.

It will be appreciated that the outer side wall 13 is the side wall surrounding the outside of the electromagnetic shield 10. The perimeter of the cross section of the outer sidewall 13 is the outer perimeter of the cross section of the outer sidewall 13, wherein the cross section is a section perpendicular to the height direction of the electromagnetic shield 10, i.e. a section perpendicular to the direction of the second end 12 towards the first end 11.

It should be understood that, since the electromagnetic shielding case 10 has the electromagnetic shielding function, the electromagnetic shielding case 10 is made of a material having the electromagnetic shielding effect, for example, the electromagnetic shielding case may be made of a metal material, and the electromagnetic shielding case may be made of a non-metal material with a metal layer disposed on the surface.

As can be seen from the above, the electromagnetic shielding case 10 provided in the embodiment of the present application has the first end 11 and the second end 12 which are oppositely disposed, and the accommodating space 101 is provided inside the electromagnetic shielding case, and the opening 102 communicated with the accommodating space 101 is provided at the second end 12, so that the wireless charging receiver 20 can be accommodated in the accommodating space 101 and receive external electromagnetic waves through the opening 102, and the electromagnetic shielding case 10 can perform electromagnetic shielding on the periphery of the wireless charging receiver, thereby being beneficial to reducing interference of a magnetic field on components around the wireless charging receiver, reducing influence of the components around the wireless charging receiver on the wireless charging efficiency, and improving stability of wireless charging. Compared with an electromagnetic shielding part with a plate-shaped structure or a sheet-shaped structure, the electromagnetic shielding case 10 with the accommodating space 101 can surround and protect the wireless charging receiver, so that the electromagnetic shielding effect is better, the influence and damage of the outside on the wireless charging receiver can be effectively reduced, the interference of external objects such as silt and obstacles higher than the ground on the wireless charging receiver can be reduced, and the safety and the service life of the wireless charging receiver are improved.

Meanwhile, by arranging the electromagnetic shielding case 10 to have the outer side wall 13 located between the first end 11 and the second end 12, the perimeter of the cross section of the end, close to the second end 12, of the outer side wall 13 is smaller than the perimeter of the cross section of the other end, close to the first end 11, of the outer side wall 13, which is beneficial to reducing the occupation of the peripheral volume of the part, close to the second end 12, of the electromagnetic shielding case 10, compared with the situation that the perimeters of the cross sections of all places of the outer side wall 13 are consistent and the situation that the perimeter of the cross section of the end, close to the second end 12, of the outer side wall 13 is larger than the perimeter of the cross section of the other end, close to the first end 11, the size of the electromagnetic shielding case 10 can be reduced, the second end 12, where the opening 102 is located, can be more easily kept away from external objects, the possibility of collision with the external objects is reduced, and the damage to the external can be reduced.

Furthermore, the object can move along the first end 11 toward the second end 12 when the object contacts the outer sidewall 13, thereby reducing the possibility that the object stays on the outer sidewall 13. In addition, when the electromagnetic shield case 10 is mounted on a device, for example, a bottom of a vehicle, the first end 11 may face the vehicle, the second end 12 may face away from the vehicle, and the electromagnetic shield case 10 may be substantially depressed, so that it is visually integrated with the bottom of the vehicle, and the appearance may be more beautiful.
