[0019] See also Figure 1-6 As shown, the utility model relates to an electronic device protective shell with an ink screen function, including a protective shell 1, wherein an ink screen 3 is arranged on the bottom surface of the protective shell 1, and the protective shell 1 is provided with a control circuit module, the control circuit module includes a main control module 43, a first connector 41, and a second interface 42, wherein the ink screen 3 is electrically connected to the main control module 43, and the first connector 41 is used for the charging interface with the electronic device 2, and the electronic device 2 realizes power supply to the main control module 43 and the ink screen 3 and data transmission through the first connector 41.
[0020] First, by integrating the ink screen 3, the electronic device 2 adds a new display function on the basis of the original function, which greatly enriches the use scenarios of the device and improves the user experience. This design not only makes the device more multifunctional, but also realizes simple and intuitive picture transmission and control through a dedicated APP, further enhancing the user's convenience and satisfaction. At the same time, the solution does not rely on the NFC function, and realizes data transmission by directly connecting the charging port of the electronic device 2, thereby improving the versatility and compatibility of the product and lowering the technical threshold. In addition, as a protective shell, it effectively provides safety protection for the electronic device 2 and reduces the risk of accidental damage. It is particularly worth mentioning that the design also retains the charging port, so that users can conveniently charge the device while enjoying the function of the ink screen 3, solving the problem of convenience of use. Finally, the energy-saving and environmentally friendly characteristics of the ink screen 3 are also in line with the current social trend of green environmental protection, which helps to reduce energy consumption and environmental pollution. In summary, your solution has shown significant beneficial effects in terms of functionality, user experience, technical compatibility, equipment protection, ease of use and environmental protection, which will greatly enhance the competitiveness and attractiveness of the product in the market.
[0021] Furthermore, a first slot 11 for placing the electronic device 2 is disposed on the surface of the protective housing 1 , and a second slot 12 for placing the control circuit module is disposed on one side of the protective housing 1 .
[0022] Through the clear design of the first slot 11 and the second slot 12, the structure of the protective shell is clearer and more reasonable. The first slot 11 ensures that the electronic device 2 can be firmly placed in the protective shell to prevent it from slipping or moving; and the second slot 12 is specifically used to place the control circuit module, so that it is separated from the electronic device 2 to reduce mutual interference and facilitate maintenance and replacement. The control circuit module is placed in the second slot 12, realizing a modular design. This design allows the control circuit module to be developed, tested and maintained as an independent unit, improving the reliability and maintainability of the product. At the same time, if the control module needs to be upgraded or replaced in the future, the user only needs to simply take out the old module and put in the new module without replacing the entire protective shell.
[0023] Furthermore, the main control module 43 is connected to the first connector 41 via a connecting wire 44, wherein an interface card slot 13 is provided on one side of the surface of the protective shell 1, the connecting wire 44 extends into the interface card slot 13 and is connected to the first connector 41, and the first connector 41 is clamped in the interface card slot 13.
[0024] The setting of the interface card slot 13 enables the connecting wire 44 and the first connector 41 to be neatly stored inside the protective shell, avoiding the mess of wires and improving the neatness and aesthetics of the product. At the same time, the design of the interface card slot 13 can also be coordinated with the overall style of the protective shell to enhance the overall appearance of the product. The first connector 41 is arranged in the interface card slot 13, so that the user can easily find and connect the electronic device 2 when using it. This design reduces the complexity of user operation and improves the convenience of use.
[0025] Furthermore, the second interface 42 extends outside the first slot 11. Extending the second interface 42 to the outside of the first slot 11 allows users to more conveniently access a charger or other device. Charging or data transmission can be performed without opening or removing the electronic device 2, which greatly improves the convenience of use. By designing the second interface 42 outside the first slot, the electronic device 2 is prevented from being frequently plugged in or moved during charging or data transmission, thereby reducing the risk of damage to the interface of the electronic device 2. At the same time, the protective case itself can also provide additional protection for the electronic device 2, reducing damage to the device interface due to accidental collisions or falls.
[0026] In addition, the second interface 42 is a USB-C interface. Due to the use of the USB-C interface, the second interface 42 is compatible with a variety of devices including the iPad, providing users with a unified charging solution. The USB-C interface supports more efficient charging standards, such as the PD fast charging protocol, to ensure that the iPad can restore power faster and reduce waiting time. USB-C headphones usually use advanced audio encoding and transmission technologies, such as USB Audio Class 2 or USB Audio Class 3, which can provide purer and higher-quality audio output, allowing users to enjoy a more realistic music experience. Compared with traditional Bluetooth or wired headphones, USB-C headphones directly transmit audio data through the USB-C interface, reducing the loss of sound quality during transmission and ensuring the integrity and originality of the audio. The charging and audio output functions are realized through a single interface, which reduces the number of cables that users need to carry, making the desktop or backpack more tidy.
[0027] Furthermore, the bottom surface of the protective shell 1 is provided with a third slot 31 for placing the ink screen 3, and a wire hole 121 connected to the third slot 31 is provided on one side of the second slot 12. The design of the third slot 31 allows the ink screen 3 to be placed inside the protective shell as an independent module. Such a modular design makes the maintenance and replacement of the ink screen 3 more convenient. If the ink screen 3 fails or needs to be upgraded, the user only needs to simply take out the old ink screen 3 and put in a new ink screen 3 without replacing the entire protective shell.
[0028] In addition, through the design of the wire hole 121, the cable can be neatly passed through the second slot 12 (where the control circuit module is located) and directly connected to the ink screen 3 located in the third slot 31. This not only simplifies the wiring process, but also ensures the neatness and orderliness of the internal circuits of the protective shell, improving the overall aesthetics of the product. The design of the wire hole 121 allows the cable to have a fixed path inside the protective shell, reducing the risk of loosening or breaking of the cable due to external factors (such as vibration, extrusion, etc.), thereby ensuring the stability of the connection between the main control module 43 and the ink screen 3.
[0029] Furthermore, the surface of the second slot 12 is covered with a sealing cover 14. The sealing cover 14 can effectively prevent dust, moisture or other contaminants from entering the second slot 12, protecting the control circuit module from damage. This is essential for maintaining the stable operation of the control circuit module and extending its service life. The design of the sealing cover 14 makes the protective shell more neat and beautiful in appearance. There is no exposed circuit or interface, making the entire product look more high-end and professional.
[0030] In the solution of this specific embodiment, in addition to connecting to the charging port of the electronic device 2 to realize data communication and power supply, a second interface 42 is also provided, which can be connected to the charger of the electronic device 2 to charge the electronic device 2, and can also be connected to the earphone to realize audio playback, so the module connection relationship of the entire system will be more complex but also more flexible.
