Description

A battery integrated converting-case that turns a used smartphone into a computer and a gateway {a battery integrated converting-case that turns a used smartphone into a computer and a gateway }

The present invention is a high-capacity battery for the purpose of converting a used smartphone to a computer body and a gateway that enables WiFi, Bluetooth, RFID, and NFC to interwork with multiple communication protocols of short-distance and mobile communication such as 3G, LTE, and 5G. The pack relates to a built-in case.

A computer is used as a desktop computer that connects external devices such as a monitor, keyboard, and mouse to a main body composed of a central processing unit (CPU), memory (RAM), input/output device (I/O card), storage device, and power supply device. A smartphone has the same structure as a computer, uses a small touch panel instead of a monitor as an external storage device, functions more than a computer using various sensors and various communication protocols, and can be connected to a mobile communication network, so it can also be used as a phone. used In other words, it is the same as adding a sensor, phone function, and short-distance communication function to a computer. Smartphones basically enable protocols such as WiFi, Bluetooth, RFID, NFC, 3G, LTE, and 5G communication, so WiFi, Bluetooth, RFID, An edge gateway function that links short-distance communication such as NFC and mobile communication with 3G, LTE, and 5G is possible. As application programs used in conventional computers are possible with smartphones, they are also commonly used as mobile computers. However, there are inconveniences due to the battery capacity problem caused by long-time use and the small screen tailored to the mobile type, but these inconveniences are being resolved as various accessories are released. Although we pay attention to the durability of the product, such as being waterproof, it is difficult to use it as an industrial computer or directly as a gateway due to the limitations of the portable nature, so it is difficult to use it as a gateway. , It is the background of this development that it can serve as an industrial computer, relay device, and gateway by reinforcing durability against dust.

As IoT and cloud use increase globally, the demand for gateways connecting IoT equipment using Bluetooth and WiFi and mobile communication LTE and 5G is continuously increasing. Therefore, equipment that connects short-range communication such as Bluetooth and WiFi and mobile communication such as LTE and 5G is required, but newly developed equipment in accordance with each country's communication laws and equipment certification laws must be certified in accordance with these laws and regulations can be used in However, this certification takes a long time and costs, and since mobile communication companies provide communication network services based on IMEI (International Mobile Equipment Identity) numbers, gateways have been certified in accordance with national laws and regulations, but additionally, the country's telecommunications companies It can be used only when the equipment is licensed by the Therefore, there is a need for a gateway or method capable of solving these problems and connecting Bluetooth and WiFi, which are short-range communication, with LTE and 5G. Currently, two types of computers are used, desktop and notebook, and they are widely used as consumables as office equipment for learning. Smartphones are generally new and changed after 2 to 3 years, and there are cases where existing smartphones are used or discarded. And recently, as smart phones, notebooks, and desktops are used in synchronization based on operating systems, the distinction is ambiguous. In this situation, as personal equipment, smartphones are continuously purchased, used products are becoming more popular than computers, and as their performance is also continuously upgraded, there is a need to reuse used resources, There are cases where the performance is not lacking even when used as a computer and a gateway that uses some functions, so there is also a resource consumption aspect. Looking around the world, 3G phones are currently being used, and the present invention is to recycle these used smartphones and to efficiently use the development, production, and sales of notebooks and gateways.

A high-capacity battery, a continuous power supply device, and an all-in-one case with a function to enhance durability are integrated with a smartphone main board that does not have a high-end smartphone or liquid crystal, but the power supply and main functions operate normally. , It can be used as a main body with CPU function, storage device, and I/O output device, and when external connection devices such as monitor, mouse, storage device, and keyboard are connected using connection ports, it can be used as a small desktop or external It can be used as an edge gateway without a connection device. This is because used smartphones can be used as IoT gate devices because most of them use protocols such as Bluetooth, WiFi, RFID, NFC and mobile communication 3G, LTE, and 5G.

Since used smartphones are all-purpose computers in the palm of your hand, their use is widely increasing in healthcare, automobiles, manufacturing, the 4th industry, distribution and transportation. However, since it is recognized for personal use, if the recognition as a personal terminal is changed, it can be used as an industrial computer and also play a very important role in the IoT-based communication ecosystem. It is already playing an important role in platform services. If it is converted to industrial use, it will play a very important role in the IoT field because it can connect humans and IoT devices and use a number of wireless communication protocols (WiFi, Bluetooth, RFID, NFC, etc.) on smartphones. Therefore, if you recycle used smartphones, which increase over time, reuse and efficiency of resources can be maximized. That is, the production of computers and gateways at the most competitive cost becomes possible.

The present invention allows a used smartphone or a smartphone body with power and main functions to be fixedly mounted inside the case in a durable case equipped with a large capacity battery, power supply unit, connection line, and antenna, so that a computer or edge gateway (edge It is an invention that enables switching to a gateway). A smartphone is largely composed of a liquid crystal module, a main board, and a power board. When the liquid crystal is broken, the liquid crystal is replaced, used, or discarded. Also, if it is used for a long time, the power will not work. In this case, if you replace the power board, it will work. Therefore, you can use a used smartphone as it is, but if the liquid crystal is damaged, there is only a main board and a power board, so you can switch to use. Conventional desktop computer assembly is produced by assembling a power supply, motherboard, and storage device based on a case, and notebooks are also completed by assembling based on modularized parts. Based on this method, it is the content of the present invention to convert a smartphone into a motherboard module, and to convert the other modules into a computer and gateway by combining them with a case provided in advance.
