Description

[Technical Field]

[0001] This application relates to a utility model of a peripheral device for mobile phones, in particular smartphones, which allows simultaneous charging of a mobile phone and an additional battery, and which aims to ensure the use of the device during long operation thanks to a power supply built into the charger itself. [Background technology]

[0002] With technological developments in the field of mobile telephony and the increasing availability of sophisticated devices at affordable prices, communication via mobile phones has become frequent and commonplace across various segments.

[0003] It has become common to see people in airports, restaurants, shopping centers, waiting rooms, etc., surprised by the lack of charge in their mobile phone batteries and searching for an outlet to charge their devices so they can resume an important conversation, participate in a business meeting, communicate with family, or take an online course.

[0004] To charge the battery of a mobile phone, a charger is used that connects to the device's internal circuitry via a cable that connects to a power outlet and the mobile phone, thereby charging the battery.

[0005] Typically, users charge their mobile phones overnight so they can be used the next day. Magnetic inductive chargers that can charge mobile phones without a power outlet are already available on the market, but they are quite expensive and need to be charged in advance. As a result, if there is only one available power outlet, the charger is left charging and forgotten.

[0006] To solve this problem, patent application BR 202021013847-0 U2 discloses a device that can simultaneously charge a mobile phone battery and an additional battery built into its structure. When the mobile phone is charged and its battery is discharged through use, the additional battery built into the charger charges the mobile phone through a connection cable to the mobile phone without the need to connect it to an outlet. Therefore, by using this peripheral device, users can charge their mobile phone battery and continue using the device without interrupting their ongoing activities, ensuring the freedom, independence, and flexibility of being able to charge their mobile phone anywhere without restricting the mobile phone's mobility.

[0007] Although this development is simple and solves the problem in a safe and peaceful way, there are still technical issues in its use related to its construction.

[0008] The first problem concerns the loss of battery charge that can occur while the device is not in use.

[0009] The second problem relates to the situation where the mobile phone and the additional battery are completely discharged. In this situation, two technical impracticalities arise given the way the devices are configured (i.e., two different power supply systems). The power supply and battery charging protection circuitry used for safe charging / discharging can develop a short circuit, damaging the power supply and / or the battery.

[0010] This application aims to solve this problem and will explain it in detail to provide a better understanding of the problem. Summary of the Invention

[0011] The utility model proposed in this specification relates to a peripheral device for mobile phones, in particular smartphones, intended to ensure the use of the device in long-term operation, so that when the battery of the mobile phone runs out, the user does not need an electrical network to charge the smartphone, but can simply use his own charger to accomplish this task, with more freedom, flexibility and autonomy, ensuring at least two full charges of his device.

[0013] The proposed utility model relates to a peripheral device for mobile phone devices, in particular smartphones, which is intended to ensure the use of the device during long periods of operation, so that the user no longer needs the electrical network to charge the smartphone when the battery of the mobile phone runs out. This new model is intended to ensure the use of the device during long periods of operation, and is capable of simultaneously charging the mobile phone and an additional battery and power supply built into the charger body.

[0014] In the currently proposed utility model entitled "Smart Charger for Mobile Phones", as set out in document BR 202021013847-0 U2, the above problems have been properly analyzed and solved.

[0015] To address this issue of the device losing charge while not in use, commercially available portable chargers have been introduced to peripheral devices that have hardware that can prevent the battery from potentially losing charge. Empirical testing conducted has not identified any such issues.

[0016] If the battery system is fully discharged, charging is performed independently to ensure safe use of the device. That is, when the device is plugged into a power outlet, the mobile phone battery will automatically start charging, and the auxiliary battery will be charged independently by the power source. Therefore, if the mobile phone battery runs out during use, the user does not need to use a power outlet, but simply connects it to the auxiliary battery.

[0017] Thus, the new utility model has the following characteristics: - a connection point to the electrical network, where the outlet is located and located on one side of the device; - A USB input for the mobile phone battery, located on the back of the device, for use by the user when the device is unplugged; two USB inputs for power supply and a charging point for the device, which are used when the device is plugged into a socket and are located on the side opposite the connection point to the electrical network; a USB input for a mobile phone battery located on the rear of the device, for use by the user when the device is not plugged into a power outlet; Two USB inputs for power supply when the device is plugged in and located on the side opposite the connection point to the electrical network, and a charging point for the device -Battery charge indicator light point located on the bottom of the device.

[0018] FIG. 1 is a perspective view of a smart charger C of the present disclosure, showing the area where the connection point (1) to the electrical network, i.e. the outlet, is located.

[0019] Figure 2 shows the charging point for the device, which includes a mobile phone battery input, USB A (2), located on the back of the device and used by the user when the device is unplugged, and two power inputs, USB B (3) and USB C (4), located on the opposite side of the connection point to the electricity network (1), and used when the device is plugged into a power outlet. These connections allow the user to charge a total of two devices, while also charging the battery itself, when the charger is plugged into a power outlet.

[0020] Figure 3 is a bottom view of the charger, showing the battery charge indicator light points (5).

[0021] It should be noted that the introduction of fast charging power sources has improved the charging performance of new chargers, allowing for optimized simultaneous charging of the mobile phone device and the charger's internal battery.

[0022] Additionally, the design developed on the outside of the charger offers improvements for the user, making the device more ergonomic and easier to store in a pocket, backpack or bag, and making the product easier to handle.
