An integrated circuit with a wireless power receiving structure and its integration method

Abstract

The invention discloses an integrated circuit with a radio energy receiving structure and an integrating method thereof. The integrating method comprises the following steps: putting a wireless charger on an independent wireless charging mainboard and arranging the wireless charging mainboard with the wireless charger and an electronic equipment mainboard with electronic equipment devices in a stacking way. Space increase caused by the thickness of an electric energy receiving coil, a magnetic shielding layer and a copper shielding layer can be used adequately and space waste can be avoided. Compared with the prior art, the integrating method disclosed by the embodiment of the invention has the advantages of good heat dissipation performance and high space utilization rate and enables electronic equipment to have a compact structure and good heat dissipation performance while integrating the wireless charging function.

Description

technical field [0001] The present invention relates to the technical field of wireless charging, and more specifically, relates to an integrated circuit with a wireless energy receiving structure and an integration method. Background technique [0002] Wireless charging technology is quickly applied to the market due to its convenience and speed. The traditional wireless charging solution is to set up a power transmitting platform and a power receiving platform. The power receiving platform is generally a shell with a wireless receiving structure, and then the power receiving platform is connected to power supply to electrical equipment. [0003] The disadvantage of the above solution is that it is necessary to separately manufacture or purchase a power receiving platform, such as a mobile phone case with a wireless receiving structure or a charging module, which will bring inconvenience to the user and cannot satisfy the user's wireless charging experience. Therefore, und...

[0003] The disadvantage of the above solution is that it is necessary to separately manufacture or purchase a power receiving platform, such as a mobile phone case with a wireless receiving structure or a charging module, which will bring inconvenience to the user and cannot satisfy the user's wireless charging experience. Therefore, under the further impetus of market demand, wireless charging technicians consider integrating the wireless receiving structure into portable electronic devices such as mobile phones, so that the mobile phone itself has a wireless charging function, such as figure 1 As shown, it is a wireless charging integration method in the prior art. The interior of the mobile phone mainly includes the battery, the main board of the mobile phone and the components on the main board to realize various functions

[0004] However, this integration scheme has certain defects. First, there are hidden heat dissipation problems. The internal components of the mobile phone are the main heat source, especially the core processing devices such as CPU (Central Processing Unit) and GPU (Graphics Processing Unit). Functional components will also produce energy loss in the process of power conversion, which will bring additional heat sources, which will increase the heat dissipation burden of the mobile phone motherboard; second, the internal space of the mobile phone is not fully utilized, such as figure 2 As shown in the side view, since the power receiving coil, magnetic shielding layer and copper shielding layer all have a certain thickness, some space is not used at the position of the main board parallel to the power receiving coil, magnetic shielding layer and copper shielding layer
