Description

  The present invention relates to a charging module for charging a mobile terminal, and more specifically, it can be used for a case alone, and charging by adding an auxiliary battery while the mobile terminal is mounted in such a case. In particular, the present invention relates to a case-type charging module for a portable terminal that is designed to provide stable protection while ensuring a sufficient rear view of the portable terminal when the auxiliary battery is separated. .

  In general, mobile terminals such as smartphones are not limited to simple call functions, but can be used in a variety of ways by providing a large LCD and displaying various images and graphics. This is a portable telephone terminal.

  Such portable terminals have a large battery consumption due to the provision of images and graphics using the large liquid crystal as described above, which recently minimizes the above-mentioned battery consumption or is carried by an auxiliary battery while being carried. Various technologies such as charging have been developed.

  However, in the case of the technology for charging the portable terminal while being carried by the auxiliary battery, the auxiliary battery and the portable terminal are separately configured, so that a separate charging cable must be further provided and separated from each other. In addition, it is inconvenient to hold the auxiliary battery and the portable terminal at the same time.

  Therefore, recently, as filed by the present applicant, there has been provided a technology that enables an auxiliary battery to be integrated with a mobile phone case. In this connection, it is as presented in Korean Patent No. 10-1441677 and Korean Published Patent No. 10-2017-0058842.

  However, since these conventional technologies are actually configured to completely cover the back surface of the mobile terminal, the back surface design of the mobile terminal cannot be seen, causing some users to be dissatisfied.

  That is, recently, the back surface of the mobile terminal is configured with a design that best exposes the characteristics of the mobile terminal. However, the back surface of the mobile terminal is effectively blocked by the auxiliary battery or case. There was dissatisfaction due to the non-exposure of the design.

  Of course, there was also a method of forming the case with a transparent material, but in this case, the connection with the auxiliary battery is not stably performed, there is an unsatisfactory that is not supported by the color of the mobile terminal, Since the case made of a transparent material is weak, it has a drawback that it cannot protect the mobile terminal against bending deformation.
