AI Technical Summary
Smartphones malfunction due to water droplets on the screen during rainy weather, causing 'ghost touch', and existing waterproof solutions trap heat, leading to thermal runaway.
A frame with a translucent sheet attached to the smartphone's outer periphery forms a gap to prevent water droplets from touching the screen and allows for heat dissipation by keeping the back open.
Prevents smartphone malfunctions and reduces overheating risks during rainy weather by using a frame with a translucent sheet that forms a gap and maintains heat dissipation.

Abstract
Description
Technical Field
[0001] The present invention relates to a rain operation assistive device for smartphones for assisting screen operations of smartphones during rainy days or the like.
Background Art
[0002] In recent years, opportunities to use smartphones for navigation and business management outdoors, such as in the delivery business of food and beverages, have been increasing. During rainy days, water droplets adhere to the screen of the smartphone, and there has been a problem of "ghost touch (malfunction)" in which the touch panel misidentifies the water droplets as fingers and causes unexpected operations. To prevent this, waterproof pouches that cover the entire smartphone are known, but there has been another problem that heat inside the device becomes trapped during summer or while charging, causing the device to stop functioning due to thermal runaway.
Summary of the Invention
Problems to be Solved by the Invention
[0003] The present invention has been made to solve the above problems, and an object thereof is to provide a rain operation assistive device for smartphones that can prevent malfunction due to water droplets on the screen during rainy days and at the same time ensure the heat dissipation of the terminal.
Means for Solving the Problems
[0004] To achieve the above object, the rain operation assistive device for smartphones of the present invention includes a frame body that is attached to the outer peripheral portion of the smartphone, and a translucent sheet that is stretched on the front side of the frame body, and is configured such that a space (gap) is formed between the translucent sheet and the screen. As a result, raindrops are received by the translucent sheet and do not directly touch the screen, preventing malfunction, and touch operations on the screen are possible by pressing the translucent sheet with a finger. Further, the frame body has a structure with an open back side, so as not to interfere with the heat dissipation of the smartphone.
Effects of the Invention
[0005] This invention reliably prevents smartphone malfunctions during outdoor work such as delivery services, especially in rainy weather. Furthermore, because the back is open, the risk of overheating due to charging or direct sunlight is significantly reduced. [Brief explanation of the drawing]
[0006] [Figure 1] This is a diagram showing the configuration of a rainy-weather operation aid (frame only) for smartphones according to an embodiment of the present invention. [Figure 2] This is a front view showing the attached state of a rain-resistant smartphone operation aid according to an embodiment of the present invention. [Figure 3] This is a cross-sectional view showing the wearing state along line AA in Figure 2. [Figure 4] Figure 2 is a cross-sectional view showing the mounting state on the BB line. [Modes for carrying out the invention]
[0007] Embodiments of the present invention will now be described with reference to the drawings. As shown in Figures 1 to 4, the rainy-weather operation aid for smartphones according to the present invention comprises a frame (1) and a translucent sheet (2). The frame (1) is attached to the outer periphery of the smartphone (10). The translucent sheet (2) is stretched over the front side of the frame (1). As shown in the cross-sectional views of Figures 3 and 4, a space is formed between the translucent sheet (2) and the screen when it is attached. [Explanation of Symbols]
