Description

[Technical Field]

[0001] This invention relates to a case for a smartphone, a mobile terminal that combines various functions with a conventional mobile phone, such as computer functionality, voice calls, SMS, Internet connectivity, a camera, GPS, and a music player. [Background technology]

[0002] In recent years, a wide variety of smartphones (hereafter referred to as "smartphones") with various functions have been released on the market, and a wide variety of cases have also been proposed to cover these smartphones, taking into consideration the shape, color, material, and structure that can be combined with the smartphone. Furthermore, many cases used for smartphones have an exterior shape similar to the smartphone itself, and are designed to fit into the smartphone.

[0003] However, these various smartphone cases are not designed with power generation / charging functions in mind, either structurally or functionally, and as a result, smartphone users who use such cases are burdened with the mental burden of constantly having to be mindful of their smartphone's battery consumption.

[0004] However, while conventional smartphones have been designed with a lens to enlarge the smartphone display surface (front surface) to make it easier for the other person to see, as in Utility Model Registration No. 3244931, such designs are designed to make the information easier to see and do not take into consideration the consumption of the smartphone's battery power, so smartphone users still have to constantly worry about battery drain.

[0005] [Patent Document 1] Utility Model Registration No. 3244931 Summary of the Invention [Problem to be solved by the invention]

[0006] Therefore, this invention focuses on the fact that organic perovskite is structurally thin and flexible among types of solar cells, and by integrating this perovskite solar cell with a transparent smartphone case, charging occurs when light is present, eliminating the need to constantly worry about the smartphone's battery charge, and providing a lightweight, simple structure and overall smart smartphone case. [Means for solving the problem]

[0007] The main feature of this device is that it is a very smart smartphone case that can always charge a smartphone in the presence of light, and that comprises a flat, rectangular smartphone body, a camera unit including a light located at a specific corner on the back of the smartphone body, a smartphone case with a peripheral structure that fits and fits to the peripheral shape of the smartphone body and has a frame through which the camera unit of the smartphone body can be viewed, a thin perovskite photovoltaic unit located within the smartphone case, and a transmission coil located between the thin perovskite and the charging function within the smartphone body and that charges the charging function within the smartphone body. [Effects of the Invention]

[0008] According to the claimed invention, a thin and flexible thin perovskite is placed on the inside surface of a transparent smartphone case, and the charger inside the smartphone body is charged via a similarly placed power transmission coil.This means that the smartphone body can be charged at all times as long as there is light, so smartphone users do not need to constantly worry about the smartphone's discharge status, and a smartphone case can be provided that maintains the convenience of using the smartphone. [Brief explanation of the drawings]

[0009] [Figure 1] FIG. 1 is an assembly diagram illustrating the structure of assembling a smartphone case and a smartphone body according to one embodiment of the present invention. [Figure 2] Figure 2 shows a plan view of the thin perovskite photovoltaic unit. [Figure 3] FIG. 3 is a plan view of the power transmission coil of FIG. DETAILED DESCRIPTION OF THE INVENTION

[0010] The smartphone case of this invention employs a structure that fits snugly with the smartphone body, ensuring a strong connection between the two. Furthermore, because the smartphone case is transparent, light shines on the thin perovskite panel placed inside without loss, generating electricity. This electricity is then supplied without loss via a power transmission coil to the charger inside the smartphone body, which is tightly fitted into the smartphone case. This means that users do not need to constantly worry about the charge level of the smartphone body. [Example]

[0011] Figures 1, 2, and 3 show one embodiment of the present invention, in which 1 in Figure 1 is a flat, approximately rectangular smartphone body (hereinafter referred to as the smartphone body) 1, and the opposite side (not shown in the figure) of the smartphone body 1 is a display unit for information, etc. A camera 2 is located in a corner on the back side of the smartphone body 1, and a light 3 is provided nearby.

[0012] A smartphone case 4 is provided on the periphery of the smartphone body 1, with a peripheral structure that fits thereto and has an opening in the shape of a viewing window 5 that corresponds to the location of the camera 2 and light 3 of the smartphone body 1. Furthermore, a thin perovskite 6 that is a photovoltaic unit is disposed between the smartphone case 4 and the smartphone body 1.

[0013] Furthermore, a power transmission coil 7, which is a wireless power supply coil, is arranged between the back surface of the smartphone body 1 and the thin perovskite 6. That is, the back surface of the smartphone body 1 has an arrangement structure in which the power transmission coil 7, the thin perovskite 6, and the smartphone case 4 are stacked in this order.

[0014] The power transmission coil 7 transmits the electricity generated by the photovoltaic unit (the perovskite) 6 to the charger of the smartphone body 1 to charge it, so there is no need to worry about the smartphone battery running out all the time, and the charge can be maintained even with little light. [Industrial Applicability]

[0015] The smartphone case of this invention is capable of generating electricity even with minimal light, and takes advantage of its transparency. By placing a thin perovskite between the smartphone case and the back of the smartphone body, its flexibility and power generation function are utilized, creating an interlocking structure between the peripheral structure of the smartphone case and the peripheral structure of the smartphone body. As a result, a smartphone case can be provided in which, with just a little light, the thin perovskite generates electricity, allowing the smartphone body's charger to be charged using a transmission coil.
