[0037] The earphone charging case is used to charge the earphones when they are inserted into the charging slot. However, most current earphone charging cases focus on improving the performance and charging efficiency of the charging case, resulting in a poor user experience.

[0038] To improve the user experience of Bluetooth headphones, such as Figure 1 and Figure 2 As shown, this utility model proposes an earphone charging case 10. In one embodiment, the earphone charging case 10 includes a case body 100, a main control board 200, and a light-emitting display board 300. The light-emitting display board 300 displays a target pattern to enhance the user experience.

[0039] In this embodiment, the housing 100 has an earphone mounting slot 130 and a first mounting position 123 and a second mounting position 113 located inside the housing 100. The earphone mounting slot 130 is used to mount earphones. It can be understood that the housing 100 is the basic structure of the earphone charging case 10, providing storage space for the earphones and serving as a carrier for the internal electronic components. Optionally, the housing 100 has an earphone mounting slot 130 on its exterior for accommodating the earphone body, ensuring that the earphones can be correctly aligned with the charging contacts for charging. The housing 100 has a first mounting position 123 and a second mounting position 113 inside for mounting electronic components.

[0040] In this embodiment, the main control board 200 is located at the first mounting position 123. The main control board 200 is used to charge the earphones when they are installed in the earphone mounting slot 130. Through the electrical connection with the earphones, the main control board 200 can intelligently manage the charging process, including current adjustment and charging status monitoring, thereby ensuring charging safety and efficiency. Optionally, the main control board 200 also integrates other functions, such as power indicator and Bluetooth pairing assistance, to further enhance the user experience.

[0041] In this embodiment, the light-emitting display panel 300 is electrically connected to the main control board 200, and the light-emitting display panel 300 has a light-emitting surface 310 for displaying target patterns. Optionally, the light-emitting display panel 300 is located at the second mounting position 113 of the housing 100 and is electrically connected to the main control board 200. The light-emitting display panel 300 is used to display various target patterns through the light-emitting surface 310. Optionally, the target patterns can convey information to the user through different colors, brightness, or dynamic effects. The light-emitting surface 310 of the light-emitting display panel 300 is positioned facing the light-transmitting portion 140 on the outer surface of the housing 100 to ensure that light can pass through the light-transmitting portion 140 to clearly display the target patterns.

[0042] Optionally, the light-emitting surface 310 refers to the side of the light-emitting display panel 300 that directly faces the user, and is used to transmit the light generated by the display unit outward so that the user can clearly see the displayed content. This light-emitting surface 310 may be specially treated to ensure that light can pass through uniformly and efficiently, and to minimize light loss and distortion. Optionally, the light-emitting surface 310 can be set with a specific output viewing angle to ensure that the user can clearly see the displayed information even when viewed from different angles.

[0043] Optionally, the light-emitting surface 310 has multiple display units, which can be LED beads, LCD panels, or other types of light-emitting elements. Each display unit can be controlled independently, and different display units can be programmed to display different colors or brightness levels, thereby combining to form various complex patterns, text, or animations. This programming control can be stored in the main control board 200, which can control the light-emitting display panel 300 to display corresponding light-emitting display modes and patterns based on this programming control logic. Alternatively, the programming control can be stored in the light-emitting display panel 300 itself.

[0044] In one feasible implementation, the earphone charging case 10 can dynamically change the displayed content according to different states or user needs. For example, when the earphones are playing music, specific patterns or animations can be displayed according to the user's personalized settings. When the earphone charging case 10 is opened, specific patterns or animations can be displayed. In this way, not only is the user's convenience improved, but the interactivity and aesthetics of the product are also enhanced, providing users with a richer and more personalized user experience.

[0045] In this embodiment, the light-emitting display panel 300 is disposed at the second mounting position 113. A light-transmitting portion 140 is provided on the outer surface of the housing 100 corresponding to the second mounting position 113. The light-emitting surface 310 of the light-emitting display panel 300 faces the light-transmitting portion 140 to display the target pattern through the light-transmitting portion 140. It can be understood that the light-transmitting portion 140 allows the light generated by the light-emitting display panel 300 to pass through the housing 100, enabling the user to see the displayed target pattern and enhancing the user's interactive experience. It should be explained that the light-transmitting portion 140 is located on the outer wall of the housing 100 at a position corresponding to the second mounting position 113, and this corresponding position can be where the light-transmitting portion 140 is directly facing the light-emitting display panel 300 on the first mounting position 123.

[0046] Optionally, the light-transmitting part 140 is made of a transparent or semi-transparent material, which can clearly display the content while maintaining the overall aesthetics of the charging case.

[0047] Optionally, the light-transmitting part 140 is integrally formed with the outer surface of the box body 100, or the light-transmitting part 140 is the outer surface of the box body 100, or the outer surface of the box body 100 has a notch, and the light-transmitting part 140 can be installed at the notch.

[0048] Optionally, the size of the luminous display panel 300 can be determined based on the size of the earphone charging case 10, or based on the content or pattern to be displayed. The specific size is not limited here.

[0049] It should be noted that the specific positions of the first mounting position 123 and the second mounting position 113 inside the housing 100 are not limited here, nor is the orientation of the light-emitting surface 310 of the light-emitting display panel 300.

[0050] It should be noted that the number of light-emitting display panels 300 can be one, two, or more. When the number of light-emitting display panels 300 is greater than one, the light-emitting surfaces 310 of the multiple light-emitting display panels 300 can face different positions. That is to say, the housing 100 has multiple second mounting positions 113 for mounting the light-emitting display panels 300. At the same time, the housing 100 also has multiple light-transmitting parts 140 to match the positions of different light-emitting display panels 300.

[0051] In summary, this invention significantly enhances the user experience through three aspects: the charging case 100, the luminous display panel 300, and the main control board 200. The charging case 100 includes a first mounting position 123 and a second mounting position 113, used to mount the main control board 200 and the luminous display panel 300, respectively. The luminous display panel 300 can intuitively display various patterns. The main control board 200 not only ensures an efficient charging process but also integrates multiple functions, such as charging control and Bluetooth pairing assistance, further enhancing ease of use. It is understood that the main control board 200 and the luminous display panel 300 are electrically connected, and the main control board 200 can control the luminous display panel 300 to display corresponding patterns. Thus, the functionality and aesthetics of the earphone charging case 10 are improved, the user's interactive experience is enriched, and the overall user experience is enhanced.

[0052] In one embodiment, such as Figure 2 As shown, the housing 100 includes a bottom shell 120 and a cover shell 110; the bottom shell 120 is provided with a first groove; the cover shell 110 is provided with a second groove, and the cover shell 110 is rotatably connected to the bottom shell 120. When the cover shell 110 is rotated to the point where the bottom shell 120 is closed, the first groove and the second groove are closed to form the earphone mounting slot 130.

[0053] In this embodiment, the housing 100 adopts a split design, consisting of a bottom shell 120 and a top shell 110, which are rotatably connected to achieve the opening and closing function. When the top shell 110 rotates relative to the bottom shell 120 and is fully closed, the first groove and the second groove together form a complete earphone mounting slot 130. In this way, not only can the earphone be securely fixed in the mounting slot when charging, but the closed structure also provides additional protection for the earphone.

[0054] Furthermore, the rotatable connection between the bottom shell 120 and the cover shell 110 enhances ease of use; users can easily open and close the cover shell 110 to remove or insert the earphones, making the operation simple and intuitive. Optionally, the rotatable connection between the bottom shell 120 and the cover shell 110 is achieved through one or more hinge mechanisms, thereby enabling the opening and closing function of the charging case. The hinges can be made of durable materials such as metal or high-strength plastic to ensure long-term reliability.

[0055] It should be noted that the specific positions of the first mounting position 123 and the second mounting position 113 are not limited here. Both can be located on the bottom shell 120, both can be located on the cover shell 110, or one can be located on the cover shell 110 and the other on the bottom shell 120. Similarly, the orientation of the light-emitting surface 310 of the light-emitting display panel 300 is not limited here. It can face the outside of the earphone charging case 10 or the inside of the earphone charging case 10. Here, "outside" refers to the outside that is exposed after the bottom shell 120 and the cover shell 110 are closed, and is directly visible to the user; "inside" refers to the inside that is closed after the bottom shell 120 and the cover shell 110 are closed, and is visible to the user when the bottom shell 120 and the cover shell 110 are open. The light-transmitting part 140 is positioned directly opposite the light-emitting surface of the light-emitting display panel 300.

[0056] In this embodiment, the bottom shell 120 has a first mounting position 123 inside, and the cover shell 110 has a second mounting position 113 inside.

[0057] Understandably, the first mounting position 123 and the second mounting position 113 are respectively located in the bottom shell 120 and the cover shell 110, allowing the main control board 200 and the light-emitting display board 300 to be reasonably distributed in the two parts of the earphone charging case 10. This optimizes the use of internal space and avoids the problem of increased thickness caused by concentrating the main control board 200 and the light-emitting display board 300 in one place. If the main control board 200 and the light-emitting display board 300 were both located in the bottom shell 120 or the cover shell 110, that part would be abnormally thick and heavy, affecting the overall aesthetics and portability of the product, and may also negatively impact the user's grip and user experience. Therefore, the first mounting position 123 and the second mounting position 113 are respectively located in the bottom shell 120 and the cover shell 110, ensuring ease of use and comfort, thereby comprehensively enhancing the user experience.

[0058] Secondly, by placing the luminescent display panel 300 within the cover 110, the user's visual habits when using the earphone charging case 10 are utilized, greatly enhancing the intuitiveness and convenience of information delivery. Since the cover 110 is located on top of the charging case in most situations, and whether open, closed, or placed normally, it is usually facing the user or in a more easily visible position, allowing the luminescent display panel 300 to interact more directly with the user. For example, when the user opens the cover to take out the earphones, or simply checks the charging status without opening the cover, the luminescent display panel 300 can use its advantageous position to display images to the user. This helps enhance the user experience.

[0059] Optionally, the earphone charging case 10 has a flat design, with both the bottom shell 120 and the cover shell 110 being flat. In this way, the luminous display panel 300 can be placed in the cover shell 110, which can have a larger display area and can display more patterns or information, thus enhancing the user experience.

[0060] In one embodiment, such as Figure 2 As shown, the cover 110 includes a first cover plate 111 and a second cover plate 112, which are closed together, and the second mounting position 113 is defined between the first cover plate 111 and the second cover plate 112.

[0061] In this embodiment, the cover 110 adopts a double-layer structure design consisting of a first cover plate 111 and a second cover plate 112. The two are combined by covering each other, forming the second mounting position 113 in the middle for mounting the light-emitting display panel 300. This fully utilizes the internal space of the cover 110 and provides a stable mounting position for components such as the light-emitting display panel 300. The limiting structure between the first cover plate 111 and the second cover plate 112 ensures the accuracy and stability of component installation, while avoiding component loosening caused by external impacts or vibrations. Furthermore, the double-layer structure design also provides a certain degree of protection, preventing external dust or foreign objects from entering, further improving the durability of the earphone charging case 10.

[0062] It is understandable that the first cover plate 111 and the second cover plate 112 are the upper cover plate and the lower cover plate, respectively (these upper and lower positions can be referenced). Figure 2 (From the perspective of the viewpoint), that is, the second cover plate 112 needs to be connected to the bottom shell 120, and the first cover plate 111 is located on the side of the second cover plate 112 away from the bottom shell 120. Optionally, one of the first cover plate 111 and the second cover plate 112 is provided with a light-transmitting part 140, and the light-emitting surface 310 of the light-emitting display panel 300 is arranged facing the light-transmitting part 140; alternatively, both the first cover plate 111 and the second cover plate 112 are provided with light-transmitting parts 140, and there are multiple light-emitting display panels 300, with the light-emitting surfaces 310 of the multiple light-emitting display panels 300 respectively arranged facing the light-transmitting parts 140 of the first cover plate 111 and the second cover plate 112. The form of multiple light-transmitting parts 140 and multiple light-emitting display panels 300 not only enhances the flexibility and diversity of information display, but also provides richer and more personalized visual feedback according to the user's perspective or usage scenario, greatly improving the user's interactive experience and the aesthetics of the product.

[0063] Alternatively, to further simplify the design and enhance the visual effect, the first cover plate 111 or the second cover plate 112, which requires the light-transmitting portion 140, can be designed as a single light-transmitting portion 140. That is, the entire cover plate can be made of transparent or translucent material, eliminating the need for separate openings or localized treatments to achieve the light-transmitting function. In this way, the light from the luminous display panel 300 can pass through the entire cover plate evenly, presenting a more complete and consistent display effect. The fully transparent design not only enhances the product's aesthetics and technological feel but also reduces the complexity of the manufacturing process and lowers production costs.

[0064] In one embodiment, such as Figure 3 and Figure 4As shown, the first cover plate 111 and the second cover plate 112 are arranged in an arc shape. The first cover plate 111 includes a first main plate 1111 and a first arc-shaped plate 1112 arranged around the first main plate 1111. The second cover plate 112 includes a second main plate 1121 and a second arc-shaped plate 1122 arranged around the second main plate 1121. The first main plate 1111 and / or the second main plate 1121 are provided with recesses that are recessed in opposite directions. The second side of the first arc-shaped plate 1112 is disposed against the first side of the second arc-shaped plate 1122 and closes the recesses to define the second mounting position 113.

[0065] In this embodiment, the first cover plate 111 and the second cover plate 112 adopt an arc-shaped design, which increases the aesthetic appeal and ergonomic comfort of the earphone charging case 10. Specifically, the first cover plate 111 consists of a first main plate 1111 and a surrounding first arc-shaped plate 1112, while the second cover plate 112 includes a second main plate 1121 and a surrounding second arc-shaped plate 1122. To form the second mounting position 113, the first main plate 1111 and / or the second main plate 1121 are provided with recesses facing each other. When the first cover plate 111 and the second cover plate 112 are closed, the inner side (second side) of the first arc-shaped plate 1112 fits against the outer side (first side) of the second arc-shaped plate 1122. This not only achieves physical closure, but also defines the recess as an independent space, namely the second mounting position 113, for accommodating components such as the light-emitting display panel 300. Thus, the arc-shaped appearance enhances the overall design and the user's grip experience.

[0066] In one embodiment, such as Figure 4 As shown, the second cover plate 112 further includes a mounting ring 1123 arranged around the second arc-shaped plate 1122, and the mounting ring 1123 is provided with a plurality of mounting portions 1124; the edge of the first arc-shaped plate 1112 is provided with mating portions 1113 that are adapted to each of the plurality of mounting portions 1124, and the first arc-shaped plate 1112 is connected to the plurality of mounting portions 1124 on the mounting ring 1123 through the plurality of mating portions 1113.

[0067] In this embodiment, as Figure 5As shown, the second cover plate 112 further enhances the connection stability between the first cover plate 111 and the second cover plate 112 by adding a mounting ring 1123 to the outside of its second arc-shaped plate 1122. The mounting ring 1123 is designed with multiple mounting portions 1124, while the edge of the first arc-shaped plate 1112 is provided with corresponding mating portions 1113 that match these mounting portions 1124. By connecting the mating portions 1113 of the first arc-shaped plate 1112 with the mounting portions 1124 on the mounting ring 1123, precise assembly and tight fixing between the first cover plate 111 and the second cover plate 112 are achieved. Furthermore, the distributed design of the multiple mounting portions 1124 and mating portions 1113 makes the force distribution more uniform, avoiding deformation or loosening problems that may be caused by localized stress concentration, further improving the durability and reliability of the earphone charging case 10, and also providing a more stable protective environment for the internal components.

[0068] Optionally, the mounting portion 1124 and the mating portion 1113 are in the form of a snap-fit ​​and a slot, respectively. The mating portion 1113 on the edge of the first arc-shaped plate 1112 is designed as a protruding snap-fit ​​structure, while the mounting portion 1124 on the mounting ring 1123 is designed as a slot structure capable of accommodating the snap-fit. Alternatively, the mounting portion 1124 on the mounting ring 1123 is designed as a protruding snap-fit ​​structure, while the mating portion 1113 on the edge of the first arc-shaped plate 1112 is designed as a slot structure capable of accommodating the snap-fit.

[0069] When the first cover plate 111 and the second cover plate 112 are closed, the groove of the first arc-shaped plate 1112 aligns with and tightly engages with the buckle on the mounting ring 1123, thereby achieving a secure connection between the two. In this way, the connection between the first cover plate 111 and the second cover plate 112 is ensured to be firm and reliable.

[0070] Of course, the mounting part 1124 and the mating part 1113 can also adopt other mechanical connection methods to meet different design requirements and usage scenarios. For example, it can be designed as a screw fixing structure, that is, a threaded hole is provided in the mounting part 1124, and a through hole is reserved in the corresponding position in the mating part 1113, and the two are fastened together by screws. Although this design increases the assembly steps, it provides higher stability and facilitates maintenance and component replacement.

[0071] In one embodiment, such as Figure 2 and Figure 4 As shown, the bottom shell 120 includes an upper bottom plate 121 and a lower bottom plate 122. The connection and fixing method between the two can refer to the connection and fixing method between the first cover plate 111 and the second cover plate 112. After the upper bottom plate 121 and the lower bottom plate 122 are connected and fixed to each other, a first mounting position 123 is formed between the two to install the main control board 200.

[0072] In one embodiment, such as Figure 5As shown, the light-emitting display panel 300 also has a process surface 320 disposed opposite to the light-emitting surface 310, and an electronic device 321 is protruding on the process surface 320; the second cover plate 112 has a mounting groove on the side facing the first cover plate 111, and the electronic device 321 is disposed in the mounting groove.

[0073] In this embodiment, the light-emitting display panel 300 includes a user-facing light-emitting surface 310 and a process surface 320 on the side facing away from the light-emitting surface 310. Electronic devices 321, such as control chips, are protruding from this process surface 320, effectively utilizing the double-sided space of the light-emitting display panel 300 and ensuring the safe installation and efficient operation of the electronic devices 321. Meanwhile, the second cover plate 112 has specially designed mounting grooves on the side facing the first cover plate 111. The positions of these grooves correspond to the electronic devices 321 on the light-emitting display panel 300, allowing the electronic devices 321 to be precisely embedded into the mounting grooves when the first cover plate 111 and the second cover plate 112 are closed. This design not only helps reduce the overall thickness and avoids unnecessary volume increase due to the protruding electronic devices 321, but also provides an additional protective layer to prevent the electronic devices 321 from being affected by external impacts or vibrations during daily use.

[0074] In one embodiment, the bottom shell 120 has a first mounting position 123 inside, and the cover shell 110 has a second mounting position 113 inside; a flexible printed circuit board 400 (FPC) is provided at the connection position between the bottom shell 120 and the cover shell 110, one end of the flexible printed circuit board 400 is connected to the light-emitting display panel 300, and the other end of the flexible printed circuit board 400 is connected to the main control board 200.

[0075] In this embodiment, as Figure 2 As shown, the bottom shell 120 and the cover shell 110 are respectively provided with a first mounting position 123 and a second mounting position 113. To achieve electrical connection between these two positions, a flexible printed circuit board 400 is provided at the connection position between the bottom shell 120 and the cover shell 110. One end of the flexible printed circuit board 400 is connected to the light-emitting display board 300 located inside the cover shell 110, which can transmit the electrical signals and data required for display; the other end is connected to the main control board 200 inside the bottom shell 120, ensuring smooth and unobstructed information and power transmission from the main control system to the light-emitting display board 300. In this way, not only is the internal wiring simplified and the space occupied reduced, but the overall structural compactness and reliability are also improved. In addition, the flexible printed circuit board 400 adapts to the needs of different opening angles, providing users with a smoother and more natural operating experience, while ensuring efficient collaborative work between the electronic components inside the earphone charging case 10.

[0076] In one embodiment, the light-emitting display panel 300 includes an LED display module and a display driver module. The display driver module is electrically connected to the main control board 200, and the main control board 200 is used to control the display driver module to drive the LED display module to display a target pattern.

[0077] In this embodiment, the LED display module can be an LED dot matrix display panel, which has multiple LED beads. The combination state of these LED beads is controlled by programming, and the programming control logic is integrated into the display driver module. Thus, the display driver module can control the LED dot matrix display panel to form various patterns, text, or dynamic effects. For example, it can be used to display the battery status of the earphone charging case 10 (such as using different icons to indicate charging, fully charged, or low battery), as well as some fun animations or personalized patterns. This design is not only powerful in function but also significantly enhances the product's technological feel and user experience.

[0078] In one feasible implementation, the LED dot matrix display panel is a 16×9 LED dot matrix display panel, where SEG1-SEG16 are row activation terminals and GD1-GD9 are column activation terminals. If it is necessary to display LED beads in the second row and second column, it is only necessary to activate SEG2 and GD2 simultaneously. It is understood that the LED dot matrix display panel can have multiple positions without LED beads, such as the first and second columns in the sixth row, thus avoiding the display of patterns in positions where patterns should not be displayed. That is, 16x9 represents the number of row and column activation terminals. Furthermore, SEG1-SEG16 of the display driving module are row driving terminals, and GD1-GD9 are column driving terminals; the SEG1 row driving terminal and the SEG1 row activation terminal are connected accordingly, and so on. For ease of understanding, subsequent LED beads need to satisfy the condition that the corresponding row activation terminal is activated (first activation state) and the corresponding column activation terminal is activated (second activation state). When a row driver is activated, it sends a signal to the corresponding row activation terminal, causing all LEDs in that row to enter the first activation state. Subsequently, when a column driver is activated, it causes the LEDs in that column to enter the second activation state. If an LED is simultaneously in both the first and second activation states, it will light up.

[0079] In one embodiment, the first mounting position 123 further includes a battery 500, that is, a battery 500 is also provided inside the bottom shell 120. The bottom shell 120 has an external interface for charging the battery 500, such as a TYPE-C interface. The battery 500 is electrically connected to the main control board 200 and is used to charge the headphones, power the light-emitting display board 300, and power the entire working system of the headphone charging case 10.

[0080] This utility model also provides a Bluetooth headset, which includes a headset body and a headset charging case 10 as described in any of the above embodiments. It should be noted that the specific structure of the headset charging case 10 refers to the above embodiments. Since the Bluetooth headset proposed by this utility model includes all solutions of all embodiments of the above-described headset charging case 10, it has at least the same technical effects as the headset charging case 10, and will not be elaborated further here.

[0081] In one embodiment, the Bluetooth earphone includes an earphone body and an earphone charging case 10. In practical applications, the Bluetooth earphone can dynamically change the displayed content according to different states or user needs. For example, when the earphone body is playing music, specific patterns or animations can be displayed according to the user's personalized settings. When the Bluetooth earphone case is opened, specific patterns or animations can be displayed. In this way, not only is the user's convenience improved, but the interactivity and aesthetics of the product are also enhanced, providing users with a richer and more personalized user experience.
