Description
Technical Field
[0001] The utility model relates to the technical field of power sockets, in particular to a compact dual-mode charging module. Background Art
[0002] With the popularity of electronic devices, people have an increasing demand for power sockets. Traditional power strips are unable to meet the increasingly diverse charging needs due to their single functions. Modular power strips have emerged. Their feature is that they are designed to be able to freely combine different functional modules. Users can choose different functional modules according to their needs, such as power socket modules, USB charging modules, network interface modules, etc., thereby realizing the diversification and personalization of power strip functions.
[0003] Although existing modular power strips can provide multiple functional modules, they lack dual-mode charging modules that support both wired charging and wireless charging. Existing modular power strips only provide separate wired charging modules or wireless charging modules, and users need to purchase and install them separately to use both charging methods at the same time, which not only increases costs but also takes up more space on the power strip.
[0004] Therefore, a dual-mode charging module that can support both wired and wireless charging is needed to meet users' needs for different charging methods and improve the space utilization of modular power strips. Utility Model Content
[0005] In order to overcome the problems existing in the related art, one of the purposes of the present invention is to provide a compact dual-mode charging module to solve the problem in the prior art that there is a lack of dual-mode charging modules that support wired and wireless charging.

[0010] A wireless charging circuit module is stacked on the main circuit module, the wireless charging circuit module is arranged close to the front side of the module housing, and the wireless charging circuit module is electrically connected to the main circuit board.
[0011] By integrating the wired charging interface and the wireless charging function into a compact module, the problem of the lack of dual-mode charging modules in existing modular power strips is solved. The main circuit board is set near the back, the interface module passes through the front, and the wireless charging circuit module is set near the front, which maximizes the use of the internal space of the module and realizes a compact design. The wireless charging circuit module is electrically connected to the main circuit module, which not only ensures functional connection, but also maintains a certain spatial separation, which is conducive to reducing mutual interference.
[0012] Preferably, a plurality of support columns are provided between the wireless charging circuit module and the main circuit module, and the wireless charging circuit module is stacked in parallel on the main circuit module via the plurality of support columns.
[0013] Using support columns to stack the wireless charging circuit module and the main circuit module in parallel can not only ensure a stable connection between the two circuit modules, but also form a certain gap between the two circuit modules, which is conducive to heat dissipation.

[0021] Dividing the front of the module shell into a wired charging area and a wireless charging area, and arranging the corresponding charging function modules close to the center of the corresponding areas, can make the functional layout of the module more reasonable, and also avoid mutual interference between the two charging methods.
[0022] Preferably, the module housing is provided with a mounting track, the mounting track is used to clip into a predetermined installation position, the mounting track is used to cooperate with a corresponding slot on the predetermined installation position to fix the charging module at the predetermined installation position, the mounting track is arranged along the length direction of the module housing, and the side of the module housing is also provided with a heat dissipation fin.
[0023] The mounting rail can quickly and stably fix the module in the predetermined installation position, and can realize the rapid disassembly and assembly of the module, which is convenient for users to replace or upgrade according to their needs. The heat dissipation fins set on the side of the module shell can increase the heat dissipation area, improve the heat dissipation efficiency, ensure the long-term stable operation of the module, and extend the service life of the module.
[0024] Preferably, the front side of the module housing is further provided with an anti-skid layer, and the anti-skid layer is arranged in the wireless charging area.
[0025] The anti-slip layer can effectively prevent the device to be charged from sliding or shifting during the wireless charging process, ensuring the stability and safety of charging, while also improving the user experience, allowing users to perform wireless charging with greater confidence.
[0026] Preferably, the diameter of the wireless charging coil is less than 50 mm.
[0027] By reducing the diameter of the wireless charging coil, the wireless charging function can be integrated into a smaller space, thereby reducing the overall volume of the module and improving the compactness of the module.
[0028] Preferably, the interface module includes at least two wired charging interfaces, and the wired charging interface is arranged perpendicular to the board surface of the main circuit board. One end of the wired charging interface is fixed on the main circuit board, and the other end points to the interface through hole.
[0029] The wired charging interface is set perpendicular to the main circuit board, with one end fixed to the main circuit board and the other end pointing to the interface through hole. This not only facilitates the installation and fixation of the interface module, but also allows the interface to extend from the front of the module housing, making it convenient for users to plug and unplug the charging cable.
[0030] The beneficial effects of the utility model are:
[0031] The utility model provides a compact dual-mode charging module, which integrates a wired charging interface module and a wireless charging circuit module in a module housing, thereby supporting both wired charging and wireless charging modes in one module, meeting the user's demand for diversified charging methods, and solving the technical problem in the prior art that the modular power strip lacks a dual-mode charging module that supports both wired and wireless charging modes. The wireless charging circuit module is stacked on the main circuit module, which effectively saves the space occupied by the modular power strip, improves space utilization, and solves the problem in the prior art that users need to purchase and install wired charging modules and wireless charging modules separately, resulting in a large space occupation. Since the main circuit module and the wireless charging circuit module are connected by electrical connection, the two charging modes can work independently and do not interfere with each other, and will not affect each other due to simultaneous use, thereby ensuring the safety and stability of charging.
