example 1

[0056] Take a metal wire with the same wire diameter (0.10mm) and wind it 13 times to make a coil. In this example, the ceramic back cover of the present invention is used. Compared with the traditional method of bonding the wireless charging RX coil and the magnetic plate together and fixing it on the battery back cover, in terms of power output, the input voltage and output voltage are set to 12V, and at 0.1A, the coil in the example of the present invention The efficiency of the coil is 58%, and the efficiency of the traditional method coil is 45%; at 0.5A, the efficiency of the coil in the example of the present invention is 81%, and the efficiency of the traditional method coil is 75%; at 1.0A, the coil in the example of the present invention The efficiency of the coil is 86%, and the efficiency of the traditional method coil is 78%. It can be seen from the data that the wireless charging efficiency of the coil corresponding to the example of the present invention is obvi...

Abstract

The invention discloses a ceramic back cover for electronic equipment, and electronic equipment with same. The inner surface of the ceramic back cover is provided with a wireless charging RX coil. Themiddle area of the inner surface of the ceramic back cover is provided with one trough for placing a wireless charging RX coil. Furthermore the inner surface of the ceramic back cover is provided with at least two wireless charging RX electrode troughs which outward extend from the middle area of the trough and the edge area of the trough, wherein the electrodes which are formed in at least two wireless charging RX electrode troughs are used as the leading-out ends of the wireless charging RX coil that is placed in the trough. Two ends of the wireless charging RX coil are soldered on the leading-out ends. The ceramic back cover of the invention is directly used as the back cover of portable electronic products such as smart phone, panel computer and wearable device. The ceramic back coverand the electronic equipment have advantages of satisfying requirements for small size and small thickness of the electronic product, and realizing relatively high wireless charging efficiency.

Description

technical field [0001] The invention relates to a housing structure of an electronic device and components thereof, a ceramic back cover used for the electronic device and the electronic device. Background technique [0002] With the widespread and high-frequency use of portable electronic devices such as smartphones, tablet computers, and wearables, people's requirements for charging are getting higher and higher. Smartphones, in particular, have powerful functions, rich software, and high frequency of use, resulting in high power consumption and short standby time. When using these products, they must be recharged repeatedly, which has become a very troublesome thing in practice. [0003] Existing portable electronic devices such as smartphones, tablet computers, and wearables do not integrate the main antenna, NFC, and wireless charging RX coil (receiving coil) into one component, but make the LDS antenna on the plastic bracket first, and use screws to Fixing together by...
