Description

Technical Field

[0001] The utility model belongs to the technical field of circuit boards, and in particular relates to a battery circuit layout and application. Background Art

[0002] Rechargeable phone cases are mobile phone accessories that combine protection and extra power, designed to address the battery life challenges faced by everyday smartphone users. As smartphone functionality continues to increase, users' demand for improved battery life is growing, especially during extended use of multimedia applications, gaming, or navigation, which can lead to battery drain. Rechargeable phone cases were developed to address this concern.

[0003] Typically, this design tightly integrates multiple components such as lithium-ion or lithium-polymer batteries, charging circuits, USB interfaces, and battery management systems into a mobile phone case to extend the battery life without affecting the normal use of the phone.

[0004] However, this battery-circuit layout has significant practical drawbacks, particularly in terms of circuit board size and space usage. Considering battery capacity, heat dissipation, and circuit stability, circuit boards are often designed to be bulky. This increases the overall thickness of the phone case, compromising portability and aesthetics.

[0005] Furthermore, oversized circuit boards occupy space that could be used for other functions or designs, limiting the trend toward thinner and lighter phone cases. For example, the increased thickness can make carrying a phone uncomfortable, especially when held for extended periods, leading to hand fatigue. Larger circuit boards also present challenges in heat management, as concentrated heat can cause battery overheating, impacting performance and safety, and even posing safety risks.

[0006] In summary, how to provide a battery circuit layout that occupies less space is a technical problem that urgently needs to be solved. Utility Model Content

[0007] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a battery circuit layout and application, which has the advantage of smaller space occupation and is conducive to reducing the volume of the circuit board.

[0008] The utility model provides a battery circuit layout, comprising a first circuit board, on which a wireless charging coil is provided;

[0009] One side of the first circuit board is electrically connected to the first battery;

[0010] One side of the first circuit board is electrically connected to the second battery pack;

[0011] The second battery pack includes at least one first battery.

[0012] Furthermore, the second battery pack includes two first batteries connected in parallel.

[0013] Furthermore, the second battery pack includes three first batteries connected in parallel.

[0014] Furthermore, it also includes a second circuit board, which is electrically connected to the second battery pack.

[0015] Furthermore, it also includes a wiring board, which spans across and contacts the second battery pack and has two ends, one end connected to the first circuit board and the other end connected to the second circuit board.

[0016] The utility model provides a battery adopting any one of the battery circuit layouts described above.

[0017] The utility model provides a mobile phone case, which adopts the battery described above.

[0018] The utility model provides a mobile phone, which adopts the mobile phone shell as described above.

[0019] As a result of adopting the above technical solution, the present invention has the following advantages and positive effects compared with the prior art, as an example:

[0020] By optimizing the battery circuit layout, the present invention can effectively reduce the volume of the circuit board, avoiding the problem of excessive circuit board size caused by battery capacity and heat dissipation requirements in traditional designs. This makes the rechargeable mobile phone case lighter and thinner, improving the user experience.

[0021] As the circuit board size decreases, the distance between the battery and the circuitry is also shortened, promoting effective heat dissipation. The optimized layout can reduce heat concentration, thereby reducing the risk of battery overheating and improving battery safety and performance.

[0022] By providing a wireless charging coil and a reasonable battery pack configuration, the present invention can achieve more efficient battery charging and management. In particular, the use of multiple first batteries in parallel can increase the total battery capacity without increasing the volume, thereby extending the battery life of the mobile phone.

[0023] The wiring board design introduced in the utility model makes the connection between the first circuit board and the second circuit board easier, simplifies the design of the overall structure, and reduces the complexity of production and maintenance.

[0024] The flexibility of the battery circuit layout enables it to be adapted to a variety of mobile phone models and brands, and has good market application prospects. BRIEF DESCRIPTION OF THE DRAWINGS
