Description

Technical Field

[0001] The present invention relates to the technical field of an earphone charging box with a lighting effect, and in particular to an earphone charging box with a lighting effect. Background Art

[0002] With the rapid development of consumer electronics, wireless earphones, owing to their portability and wireless nature, have become a mainstream product in the audio market. As a core accessory for wireless earphones, earphone charging boxes are also evolving from simple charging functions to intelligent, user-friendly, and personalized features. Traditional earphone charging boxes rely primarily on physical indicators or simple LED lights for status display, but suffer from limited display information and a poor interactive experience. Users can only roughly determine whether charging is complete by the color of the light, but lack real-time access to more detailed information such as battery level, earphone charging progress, and device connection status. This results in a lack of intuitive feedback during use. Traditional lighting systems are independent of the core functional modules of the charging box, resulting in fixed lighting display modes and inability to dynamically adjust based on the charging box's real-time operating status (such as battery charging stage, earphone insertion / removal status, and user operation commands). This makes it difficult to meet users' demands for personalized appearance and intelligent interaction. To address these issues, a headphone charging box with lighting effects is proposed. Summary of the Invention

[0003] In response to the shortcomings of the existing technology, the present invention provides an earphone charging box with lighting effects, which solves the problem that the traditional lighting effect system and the core functional modules of the charging box are independent of each other, the lighting effect display mode is fixed, and it cannot be dynamically adjusted according to the real-time working status of the charging box (such as battery charging stage, earphone insertion / removal status, user operation instructions, etc.), making it difficult to meet users' needs for personalized appearance and intelligent interaction.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: an earphone charging box with lighting effects, comprising an earphone box body, an earphone charging base located in the middle of the earphone box body, a heat dissipation component arranged at the rear section of the earphone box body, a light strip control component located inside the earphone box body and arranged in a ring, as well as a power module, a battery module, a charging control module, an earphone charging interface, a lighting effect control module, a lighting effect module, an earphone insertion detection module and a user interaction module, wherein the power module is used to connect to an external power supply to power the entire system and charge the battery module; the battery module is used to store electrical energy and power other modules; the charging control module The control module is used to monitor the charging status of the battery and earphones and control the charging process; the earphone charging interface is set on the earphone charging base for charging the earphones; the lighting effect control module controls the lighting effect module to display lighting effects of different colors, brightness and flashing frequencies according to the battery charging status of the charging box, the earphone charging status, the earphone insertion status and the user operation instructions; the earphone insertion detection module detects whether the earphones are placed in the earphone charging base; the user interaction module receives user operation instructions; the heat dissipation component is used to reduce the heat generated by each module in the charging box when it is working; the light strip control component is connected to the lighting effect control module to drive the ring-shaped lighting effect modules to emit light.

[0007] A further improvement is that the heat dissipation component includes a heat sink, a heat dissipation fan and a temperature sensor. The heat sink fits tightly against the heating module in the charging box. The temperature sensor monitors the internal temperature of the charging box in real time. When the temperature exceeds the set threshold, the heat dissipation fan starts automatically. The heat dissipation fan outlet of the heat dissipation component is arranged on the rear surface of the earphone box body.

[0008] A further improvement is that the light strip control component includes a driving circuit board and a ring-shaped light strip mounting groove. The ring-shaped light strip mounting groove is arranged around the inside of the earphone box body, and the lighting effect module is installed in the ring-shaped light strip mounting groove. The driving circuit board is electrically connected to the lighting effect control module for driving the lighting effect module to display different lighting effects.

[0009] A further improvement is that the power module is connected to an external power supply through a charging cable, and outputs charging current to the battery module, and outputs operating voltage to the charging control module, lighting effect control module, etc.; the power module is provided with overvoltage protection, overcurrent protection and short-circuit protection circuits.

The centrally located charging base ensures stable charging, while the ring-shaped light strip control components surround the core area to maximize the lighting effect. The heat dissipation components are independently positioned at the rear to avoid interference. These components work closely with functional modules such as the power module and charging control module, improving space utilization while achieving deep synergy between charging management, status display, and heat dissipation protection, thereby enhancing overall product performance.

When charging is complete, the lighting effect module 10 displays a solid green light. When the headphone is placed in the charging case for charging, the lighting effect module 10 displays a blue breathing light effect.

[0021] Working principle: When the earphone charging box needs to be replenished with power, the power module 5 is connected to an external power source such as a USB charger or a mobile power supply through a charging cable. Its built-in overvoltage protection, overcurrent protection and short-circuit protection circuits first perform a safety test on the input power to ensure that abnormal voltage or current will not damage internal components; after the test is passed, the power module 5 outputs a stable charging current to the battery module 6 on the one hand, and provides a continuous working voltage for other modules such as the charging control module 7 and the lighting effect control module 9 on the other hand; the battery module 6 uses a lithium battery and integrates a battery management system BMS. During the charging process, it monitors its own power, voltage, temperature and other parameters in real time, and feeds back this status information to the charging control module 7 through the data bus; the charging control module 7 dynamically adjusts the charging strategy according to the battery status: when the battery power is lower than 20%, the power module 5 is controlled to charge quickly in a constant current mode such as 0.5C current to shorten the charging time; when the power reaches more than 80%, it switches to a constant voltage mode such as 4.2V constant voltage to avoid damage to the battery caused by overcharging; When the user places the earphones on the earphone charging base 2 in the middle of the earphone box body 1, the groove of the earphone charging base 2 is precisely adapted to the shape of the earphones, ensuring that the earphone charging interface 8 is in close contact with the earphone contacts; at this time, the earphone insertion detection module 11 on the side of the earphone charging base 2, such as a Hall sensor or a micro switch, determines whether the earphones are inserted by detecting the physical contact signal of the contacts, and simultaneously transmits the "earphones in place" signal to the charging control module 7 and the lighting effect control module 9; after receiving the earphone insertion signal, the charging control module 7 immediately sends a handshake signal to the earphone battery through the earphone charging interface 8 to confirm the charging status of the earphones, such as whether charging is required, the charging current requirement, etc., and allocates power according to the remaining power of the battery module 6; if the battery module 6 has sufficient power, such as greater than 50%, the earphones are charged first; if the power is insufficient, such as less than 20%, the earphone charging is suspended to ensure the battery life of the charging box itself; during the charging process of the earphones, the earphone charging interface 8 provides real-time feedback on the charging progress of the earphones, such as the charged amount, charging current fluctuations, etc., to the charging control module 7, which then synchronizes the information to the lighting effect control module 9; The lighting effect control module 9 serves as the core interactive hub and integrates multi-source signal processing functions; Charging status signal: receives the battery charging stage constant current charging, constant voltage charging, charging completion and earphone charging status charging, charging completion, charging abnormality sent by the charging control module 7; Device status signal: receives the headphone insertion / removal status from the headphone insertion detection module 11; User command signal: Receives operation instructions from the user interaction module 12, such as long press to check the battery level and short press to switch the lighting effect mode; based on different signal combinations, the lighting effect control module 9 sends corresponding control instructions to the light strip control component 4: When the charging box is charging its own battery module 6, the light strip control component 4 drives the ring-shaped lighting effect module 10 to flash red light at a frequency of 1Hz to prompt the user "charging"; when the battery is fully charged, the lighting effect module 10 switches to a solid green light, and at the same time displays the specific battery level through the indicator light of the user interaction module 12, such as four grid lights representing 100%; when the earphones are placed in the charging base 2 for charging, the lighting effect module 10 starts the blue breathing light effect, with the brightness gradually changing from 0% to 100% and then back down, until the earphones turn to a solid white light after charging is completed; When the user presses the physical button or touch-sensitive area of the user interaction module 12, the lighting effect module 10 can switch to a color cycle mode or a custom lighting effect that needs to be preset through the supporting APP to meet personalized needs; the annular light strip mounting groove of the light strip control component 4 surrounds the interior of the earphone box body 1. The lighting effect module 10 uses an RGB-LED array and achieves 16 million colors through the driver circuit board. Precise control ensures that the light evenly covers the edge area of the charging box and enhances the visual effect. The heat dissipation component 3 provided at the rear section of the earphone box body 1 includes a heat sink, a cooling fan and a temperature sensor, forming a temperature control system that combines passive and active heat dissipation: Passive heat dissipation: The heat sink is tightly attached to the heating components such as the battery module 6 and the charging control module 7. The heat is quickly absorbed by the thermally conductive silicone and then transferred to the outside through the metal shell of the earphone box body 1. Active heat dissipation: When the temperature sensor detects that the internal temperature of the charging box exceeds 50°C, the cooling fan is automatically triggered to start, expelling hot air through the air outlet on the rear surface, while drawing in cold air to form convection; the fan speed is intelligently adjusted according to the temperature gradient, such as low speed at 50-55°C and high speed above 55°C, to achieve a balance between heat dissipation efficiency and noise control; The earphone box body 1 adopts a split upper cover and lower box body structure, which is opened and closed by a hinge connection; the earphone charging base 2 is fixed at the center of the lower box body, and a circular space is reserved around it for installing the light strip control component 4, ensuring that the lighting effect module 10 is arranged around the charging area, visually highlighting the core functional area; the heat dissipation component 3 is located in an independent cavity at the rear section, separated from the front functional area by a guide groove, to prevent the heat dissipation airflow from affecting the charging stability of the earphone, and at the same time utilize the narrow space at the rear end of the box body to optimize the heat dissipation path and improve the heat dissipation efficiency; through the systematic coordination of the above components, the earphone charging box realizes the deep integration of charging management, status display, and heat dissipation protection, which not only meets the user's demand for device status visualization, but also ensures the reliability of long-term use through intelligent temperature control, and at the same time enhances the product's personalization and aesthetics through the ring light effect design.
