Problems solved by technology
[0006] However, in the case of the charging method as described above, use in places other than homes or offices where AC power is not supplied is limited, or when the vehicle is not running, it is necessary to start the vehicle independently for charging, which is troublesome.
[0007] Thus, carry the auxiliary battery separated from the mobile phone, and replace the battery when the battery installed in the mobile phone is exhausted, so that the mobile phone can continue to be used anytime and anywhere, but this battery is inconvenient due to the need to carry it, and there is also a risk of loss, and It often happens that it is broken due to carelessness or external impact during carrying
[0008] As a result, cell phone cases have been proposed to accommodate the auxiliary battery, but this has limitations as it only provides the functionality of simply housing the auxiliary battery

The present invention relates to a protective casing for a portable terminal with a built-in auxiliary battery, the casing comprising: a casing body for covering and protecting the side surfaces and the rear surface of a portable terminal; a battery mounting part, located on the rear surface of the casing body, for supporting the attachment and detachment of an auxiliary battery; a battery power supply part for applying charging power of the auxiliary battery to the portable terminal when the auxiliary battery is installed in the battery mounting part; a battery wireless charging part for receiving wirelessly transmitted power to charge the auxiliary battery; and an additional component mounting part, disposed on the rear surface of the casing body, for supporting mounting of the battery wireless charging part.
Description
technical field [0001] The present invention relates to a portable terminal protective case, in particular to a portable terminal protective case with a built-in auxiliary battery for providing auxiliary power to the portable terminal and capable of wirelessly charging the auxiliary battery. Background technique [0002] In recent years, in portable terminals such as smartphones and tablet PCs, mobile phones are used while moving, so unlike wired phones that are powered while being used at a fixed location, batteries should be used as power sources. important. [0003] As phones get miniaturized, these batteries tend to get thinner. When the battery power is exhausted due to use of the mobile phone, the battery needs to be recharged. However, not only the volume of calls itself has increased, but also various functions such as video recording, multimedia, and the Internet have been further realized, so the consumption of the battery has increased, and the importance of cha...
