[0032] Traditional wireless charging devices can often only charge devices at a fixed angle or position, lacking flexibility and adaptability. Especially in different usage scenarios (such as on a desktop, bedside, in a car, etc.), it is difficult to meet the diverse needs of users. In addition, traditional charging devices are not convenient enough for storage and carrying, taking up a relatively large amount of space. In response to this, some multi-module wireless charging stands in the prior art adopt a soft glue connection technology, achieving folding storage between multiple modules and reducing space occupation. However, the soft glue material lacks support force and is difficult to meet the requirements of being an electronic device bracket. Therefore, it is particularly important to design a multi-module wireless charging device that can flexibly adjust the angle, is convenient for storage and carrying.

[0033] Please refer to Figures 1 to 4 , an embodiment of the present utility model discloses a multi-module wireless charging device, which includes: a first module 1 and a second module 2. A wireless transmitting coil 11 is provided in the first module 1, and the wireless transmitting coil 11 is used to convert the input electric energy into magnetic energy and emit it. A plasticizable part 4 is connected between the first module 1 and the second module 2, so that the relative angle between the first module 1 and the second module 2 is adjustable and fixable. It can be understood that one side of the first module 1 is connected to one side of the second module 2 through the plasticizable part 4. Due to the plasticity of the plasticizable part 4, the relative angle between the first module 1 and the second module 2 can change arbitrarily and be fixed. For example, the first module 1 can be attached to the second module 2, that is, the relative angle between the first module 1 and the second module 2 is 0°; for another example, the first module 1 can be perpendicular to the second module 2, that is, the relative angle between the first module 1 and the second module 2 is 90°; for another example, the first module 1 and the second module 2 can be in the same plane, that is, the relative angle between the first module 1 and the second module 2 is 180°. Therefore, in this embodiment, the first module 1 serves as a charging module that directly powers the terminal product, and the second module 2 serves as a bracket module that provides different angle supports for the first module 1, so that the first module 1 and the second module 2 can form brackets with various different angles to facilitate product charging, and the first module 1 can be completely attached to the second module 2 for convenient storage. Preferably, the first module 1 and the second module 2 have the same shape and size.

[0034] In this embodiment, the first module 1 and the second module 2 are connected by a plasticizable part 4. Initially, they can be at any relative angle, but for convenient carrying and storage, they are usually set in a fitting state (0°). According to the needs, the user manually adjusts the shape of the plasticizable part 4 to rotate the first module 1 relative to the second module 2 to the required angle (such as 90°, 180°, etc.). Due to the plasticity of the plasticizable part 4, the user can easily achieve precise angle adjustment. After adjusting to the required angle, the plasticizable part 4 will maintain its shape, thus fixing the relative positions of the first module 1 and the second module 2 to ensure stability during the charging process. Through the design of the plasticizable part 4, the user can easily adjust the relative angle between the first module 1 and the second module 2 to meet the charging requirements in different scenarios.

[0035] Furthermore, a control circuit board 12 is built into the first module 1, and the control circuit board 12 is electrically connected to a wireless transmitting coil 11. A first battery 21 is built into the second module 2, and the first battery 21 is electrically connected to the control circuit board 12. The built-in first battery 21 enables the device to still maintain a certain working ability when disconnected from an external power source, enhancing the flexibility and convenience of use. Preferably, a flexible circuit board 5 is connected between the first module 1 and the second module 2. One end of the flexible circuit board 5 is connected to the first battery 21, and the other end is connected to the control circuit board 12 to conduct the circuit between the control circuit board 12 and the first battery 21. Preferably, a soft glue layer 6 is also connected between the first module 1 and the second module 2, and both the flexible circuit board 5 and the plasticizable part 4 are wrapped in the soft glue layer 6. Preferably, the soft glue layer 6 is made of TPU / TPE material.

[0036] Furthermore, a charging output interface 14 is provided on the first module 1. The charging output interface 14 is electrically connected to the control circuit board 12 and is used to connect an external charging cable and supply power to it. By adding the charging output interface 14, the multi-module wireless charging device in this embodiment is not only limited to the wireless charging function but can also be used as a power source for traditional wired charging, improving its practicality and compatibility. The user can, according to the needs, use the multi-module wireless charging device in this embodiment as a charging center for various devices to meet the charging requirements of different devices.

[0037] Specifically, an activation switch 13 is provided on the first module 1. The activation switch 13 is electrically connected to the control circuit board 12 and is used to activate the working state of the control circuit board 12. It can be understood that in the unused or unactivated state, the multi-module wireless charging device in this embodiment will not consume energy for wireless charging or other operations, thus saving energy and extending the battery life. The activation switch 13 activates the multi-module wireless charging device in the unactivated state, enabling the first battery 21 to smoothly supply power to the wireless transmitting coil 11 and / or the charging output interface 14 through the control circuit board 12.

[0038] Specifically, a display screen 15 is provided on the side of the first module 1 facing the electromagnetic emission direction of the wireless emission coil 11. The display screen 15 is used to display the remaining power and working status of the multi-module wireless charging device. It can be understood that the control circuit board 12 continuously monitors the power and working status of the multi-module wireless charging device, such as battery voltage, charging current, charging status, etc., processes the monitored data, calculates key information such as remaining power and charging progress, and the display screen 15 presents the key information such as remaining power and charging progress in the form of numbers, icons or texts. Users can directly observe the remaining power and working status, and make corresponding decisions according to the information on the display screen 15, such as whether to charge the multi-module wireless charging device, whether to adjust the usage method, etc.

[0039] Specifically, the plastic part 4 is made of nickel-titanium metal material. It can be understood that nickel-titanium alloy has unique shape memory effect and superelasticity, and can produce large deformation under external force without breaking. Using nickel-titanium alloy material for the plastic part 4 can achieve more complex deformation while ensuring the structural strength, thus improving the overall performance and reliability of the product.

[0040] In another embodiment, a third module 3 is further included. The first module 1, the second module 2, and the third module 3 are connected in sequence. The third module 3 is internally provided with a second battery 31, and the second battery 31 is electrically connected to the first battery 21. It can be understood that by introducing the third module 3 and internally providing the second battery 31, the multi-module wireless charging device of this embodiment can have a larger battery capacity, thus extending the overall usage time. In addition, the modular design enables users to choose whether to add the third module 3 according to actual needs, improving the adaptability and scalability of the product. Preferably, a flexible circuit board 5 is provided between the second module 2 and the third module 3. One end of the flexible circuit board 5 is connected to the first battery 21, and the other end is connected to the second battery 31. Preferably, a soft glue layer 6 is provided between the second module 2 and the third module 3, and the flexible circuit board 5 is wrapped in the soft glue layer 6.

[0041] Furthermore, magnetic attraction sheets 7 are provided on the first module 1, the second module 2, and the third module 3. When any two of the first module 1, the second module 2, and the third module 3 are attached to each other, the magnetic attraction sheets 7 attract each other to provide a tightening force for the attachment. It can be understood that by providing magnetic attraction sheets 7 on the first module 1, the second module 2, and the third module 3, when these modules are attached to each other, the magnetic attraction sheets 7 can automatically tighten, ensuring a stable connection between the modules. This not only simplifies the process of manually aligning and fixing the modules by the user, but also makes the device more compact and convenient to carry and store.

[0042] Furthermore, an anti-slip layer is provided on the surface of the second module 2 and / or the third module 3. Preferably, the anti-slip layer is made of TPU / TPE material. It can be understood that the design of the anti-slip layer is aimed at increasing the friction between the module and the user's hand or other contact surfaces, preventing accidental dropping or damage caused by sliding during use. At the same time, choosing high-quality materials such as TPU / TPE as the anti-slip layer can further improve the user's holding comfort and feel.

[0043] Furthermore, the first module 1, the second module 2, and the third module 3 have the same shape and size, which enables users to more conveniently combine and stack these first module 1, second module 2, and third module 3 to adapt to different usage scenarios and requirements. In addition, the uniform shape and size also help to improve the aesthetics and neatness of the product, making the entire device more harmonious and unified visually.

[0044] Compared with the prior art, in the multi-module wireless charging device of the present utility model, due to the plasticity of the plastic part, the relative angle between the first module and the second module can be easily adjusted.
