Therefore, they should not be construed as limitations on this application.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] Please refer to the following: Figure 1 and Figure 2 The earphone charging case assembly provided in this application embodiment will now be described. The earphone charging case assembly includes a charging case body 100, a charging case lid 200, and an earphone body 300; the opening end of the charging case body 100 has a notch 101 that penetrates through the charging case body 100; the charging case lid 200 covers the opening end of the charging case body 100; the earphone body 300 is placed in the charging case body 100, and the handle 302 of the earphone body 300 is located at the notch 101.

[0023] Compared with the prior art, the headphone charging case assembly provided in this application provides a through-hole 101 at the opening of the charging case body 100, which naturally exposes the handle 302 of the headphone body 300 in the area of ​​the through-hole 101. Users can directly grasp the handle 302 to complete the take-out and put-in operation without having to penetrate deep into the charging case body, effectively solving the problem of difficulty in taking out the headphones caused by traditional closed compartment designs and greatly improving the convenience of taking out the headphones. At the same time, this through-hole 101 design, combined with the structural layout of the headphone body 300, allows users to quickly enter the wearing process after taking out the headphones, reducing operation steps and further optimizing the user experience. In addition, the unique shape of the through-hole 101 also creates a differentiated feature in the product's appearance, enhancing product recognition and solving the problem of homogeneous appearance in traditional charging cases.

[0024] In one embodiment of this application, please refer to the following: Figure 2 and Figure 5 The head of the earphone body 300 is the ear inlet 301, and the tail of the earphone body 300 is the hand-held part 302; the hand-held part 302 is rotatably connected to the ear clip bracket 303, and the ear clip bracket 303 can be swung to cooperate with the earphone body 300 and clamp on the user's ear.

[0025] In this embodiment, the rotation angle of the ear clip 303 can be flexibly adjusted within a preset range to adapt to the shape and size of different users' earlobes. When a user wears the headphones, they only need to swing the ear clip 303 according to their own ear structure to form a stable clamp with the inner side of the earlobe or the concha, which can effectively enhance the stability of the headphones and prevent them from easily falling off in dynamic scenarios such as exercise and walking. This rotatable ear clip 303 design not only accommodates the ear characteristics of more people, but also balances the stability and comfort of wearing the headphones by adjusting the clamping force, solving the problems of poor fit and easy slippage of traditional headphones.

[0026] In one embodiment of this application, please refer to Figure 5 The handheld part 302 is provided with a connecting shaft 304, and one end of the clamp bracket 303 is hinged to the connecting shaft 304.

[0027] In this embodiment, the hinged connection between the connecting shaft 304 and the ear clip bracket 303 provides a stable rotation fulcrum for the ear clip bracket 303, ensuring smooth rotation and preventing loosening during adjustment. The hinge structure of the connecting shaft 304 and the ear clip bracket 303 employs a damping design, allowing the ear clip bracket 303 to maintain any adjustment angle during rotation. This avoids arbitrary wobbling in the undamped state and provides users with a smooth and controllable adjustment feel. Compared to traditional fixed-angle designs or elastic buckle structures, this damping hinge method not only simplifies the adjustment operation but also extends the service life of the ear clip bracket 303, reduces structural wear caused by frequent adjustments, and ensures the structural stability of the headphones under different wearing conditions.

[0028] In one embodiment of this application, the ear clip bracket 303 has a clamping state and a placement state. In the clamping state, the ear clip bracket 303 is set at an acute angle to the handheld part 302; for example... Figure 2 As shown, in the placement state, the ear clip bracket 303 is set perpendicular to the hand-held part 302.

[0029] In this embodiment, the ear clip 303 is designed to switch between a clamping state and a placement state, achieving multi-functionality. When the user needs to wear the headphones, the ear clip 303 is adjusted to a clamping state at an acute angle with the handheld part 302. At this time, the ear clip 303 can closely fit the head contour and maintain a stable angle with the damping hinge structure, ensuring that the headphones are securely worn and do not slip off. When the headphones are not in use, the user can rotate the ear clip 303 to a placement state perpendicular to the handheld part 302. In this state, the overall structure of the headphones is more regular, making it easier to store and reducing the space occupied in storage. At the same time, it avoids unnecessary angular displacement of the ear clip 303 due to external impact when idle, further improving the convenience of product use and the reliability of the structure.

[0030] In one embodiment of this application, a limiting structure is provided on the handheld part 302, which is used to limit the rotation angle of the ear clip bracket 303 when it is placed.

[0031] In this embodiment, the limiting structure can be specifically set as a protruding stop or an arc-shaped limiting groove. When the ear clip bracket 303 rotates from the clamping state to the placement state to a vertical position, the side wall of the ear clip bracket 303 will abut against the stop or embed into the limiting groove, thereby precisely limiting its continued rotation. This ensures that the ear clip bracket 303 can be stably kept in a vertical state each time it is stored, avoiding structural damage due to excessive rotation or interference with the internal structure of the charging case 100 during storage. This design not only simplifies the user's storage operation, allowing the placement of the earphone body 300 without deliberately aligning the angle, but also improves the consistency and reliability of the product structure through mechanical limiting, solving the storage difficulties or structural collision problems caused by angular deviation of the ear clip bracket 303 in the placement state.

[0032] In one embodiment of this application, please refer to Figure 4 The charging case 100 has a first receiving groove 102 inside, which is adapted to the contour of the earpiece 301.

[0033] In this embodiment, the first receiving slot 102 is precisely modeled based on the three-dimensional contour of the earpiece 301 and integrally molded using injection molding. This ensures that the earpiece 301 fits tightly against the slot wall after being placed inside, thus positioning and fixing the earphone body 300. This contour-fitting design not only prevents the earphone from shifting laterally or vertically within the charging case but also ensures precise alignment between the earphone's charging contacts and the corresponding contacts within the charging case, guaranteeing stability during charging. Simultaneously, the fitted receiving structure reduces the gap between the earphone and the slot wall, minimizing noise caused by shaking during transportation or carrying, and enhancing the overall quality of the product.

[0034] In one embodiment of this application, the inner wall of the first receiving groove 102 is provided with a flexible buffer layer, which can form a wrap-around protection for the earphone body 301 when the earphone body 300 is placed in.

[0035] In this embodiment, the flexible buffer layer is made of high-density memory foam, which has numerous tiny pores inside. It can absorb the impact when the earphone body 300 is inserted through its own elastic deformation, preventing rigid collision between the earpiece 301 and the inner wall of the first receiving groove 102. Simultaneously, the memory foam material possesses excellent resilience and plasticity, allowing it to adaptively adjust its fit according to the specific contours of the earpiece 301, forming a 360-degree seamless enclosure. This not only prevents scratches and pressure damage that may occur during daily use but also effectively isolates external dust and moisture from intruding into the acoustic components of the earpiece 301, extending the earphone's lifespan. Furthermore, the surface of this flexible buffer layer is treated with antibacterial agents to inhibit bacterial growth, maintaining the cleanliness and hygiene of the contact area of ​​the earpiece 301 and improving the user's health and safety during wear.

[0036] In one embodiment of this application, please refer to Figure 4 The bottom of the notch 101 is provided with a second receiving groove 103, which is adapted to the contour of the clip bracket 303.

[0037] In this embodiment, the contour design of the second receiving slot 103 strictly matches the external dimensions of the ear clip bracket 303 in its placed state. When the earphone body 300 is placed into the charging case 100, the vertically positioned ear clip bracket 303 can be precisely embedded in the second receiving slot 103, achieving independent positioning and fixation of the ear clip bracket 303. This independent receiving structure avoids contact and collision between the ear clip bracket 303 and other parts of the charging case 100. At the same time, in conjunction with the positioning of the ear inlet 301 by the first receiving slot 102, the earphone body 300 forms a stable "two-point support" placement state in the charging case, effectively preventing the earphone from shifting during transportation or shaking. The depth and width of the second receiving slot 103 are optimized to ensure that the ear clip bracket 303 can be smoothly inserted and removed, and the slight interference fit between the slot wall and the ear clip bracket 303 enhances the structural stability, further improving the storage and protection effect of the charging case on the earphone body 300.

[0038] In one embodiment of this application, the cross-sectional shape of the notch 101 is rectangular or semi-circular. A rectangular notch 101 is easy to mold and form, has a simple manufacturing process, and its smooth edges create a unified visual effect with the overall angular style of the charging case 100, making it suitable for products pursuing a minimalist industrial design. A semi-circular notch 101, on the other hand, reduces sharp edges through a rounded transition, improving the tactile safety when users take out and put away the earphones. Simultaneously, the rounded contour blends naturally with the rounded shape of the earphone body 300's handle 302, enhancing the overall aesthetics of the product. The design of these two cross-sectional shapes can be flexibly selected according to the appearance positioning and usage scenarios of different products. A rectangular notch 101 is more suitable for business-style earphones, emphasizing structural rigidity and functionality, while a semi-circular notch 101 is more suitable for fashionable consumer earphones, highlighting the softness and approachability of the design.

[0039] In one embodiment of this application, please refer to the following: Figure 3 and Figure 4 The edge of the opening end of the charging box 100 is provided with a hinge seat 104. One end of the charging box cover 200 is rotatably connected to the hinge seat 104 through a hinge shaft, so that the charging box cover 200 can be flipped open and closed relative to the charging box 100 around the hinge shaft.

[0040] In this embodiment, the hinge base 104 is integrally molded with the charging case body 100 using an integrated injection molding process, ensuring the strength and stability of the connection structure and preventing loosening or breakage during long-term flipping. The diameter of the hinge shaft and the shaft hole size of the hinge base 104 are precisely calculated, and combined with a wear-resistant material with a low coefficient of friction, the flipping action of the charging case cover 200 is smooth and without jamming, and can be suspended at any angle, making it convenient for users to take out and put in the earphones with one hand. At the same time, anti-detachment baffles are provided at both ends of the hinge shaft to prevent the charging case cover 200 from axially displacing during opening and closing, which could cause it to fall off, further improving the reliability and service life of the overall structure of the charging case.

[0041] In one embodiment of this application, two earphone bodies 300 are provided, and the two earphone bodies 300 are placed in a straight line inside the charging case 100. This straight-line arrangement makes full use of the internal longitudinal space of the charging case 100, allowing the two earphone bodies 300 to be arranged sequentially along the length of the charging case 100. This avoids the problem of excessive case width that may be caused by traditional side-by-side designs, effectively reducing the overall size of the charging case and making it more convenient for users to carry around. At the same time, the straight-line placement ensures that the retrieval and placement paths of each earphone body 300 are independent, so that the user will not interfere with the other when taking out one earphone, making the operation process smoother.

[0042] In one embodiment of this application, the charging case 100 is provided with a magnetic structure, which can attract and fix the earphone body 300 to the charging case 100 to prevent the earphone body 300 from shaking.

[0043] In this embodiment, the magnetic attraction structure includes a first magnet disposed at the bottom of the charging case 100 and a second magnet embedded in the outer shell of the earphone body 300. The magnetic poles of the first and second magnets are arranged with opposite polarities, using strong magnetic force to achieve rapid alignment and stable attraction between the earphone body 300 and the charging case 100. The arrangement of the magnets matches the center of gravity of the earphone body 300, ensuring that the earphone body 300 can naturally fall into the receiving slot and maintain an upright posture during attraction, avoiding poor charging contact due to positional misalignment. At the same time, the magnetic strength of the magnetic attraction structure has been adjusted multiple times to ensure that the earphone body 300 will not accidentally fall off during daily use, while allowing users to easily separate it with only a slight external force when taking it out or putting it in, thus balancing ease of use and structural stability.

[0044] In one embodiment of this application, the inner wall of the charging case 100 is further provided with a guide slope. This guide slope extends inclinedly inward from the opening end of the charging case 100, guiding the earphone body 300 during placement. This allows the earphone body 300 to quickly slide into the first receiving slot 102 and complete positioning, reducing the need for manual alignment by the user. The guide slope features a smooth arc transition design, preventing sharp edges from scratching the surface of the earphone body 300. Combined with the magnetic structure, it forms a dual positioning mechanism of "mechanical guidance + magnetic adsorption," further improving the convenience and accuracy of placing the earphone body 300.

[0045] In one embodiment of this application, the inner side of the charging case lid 200 is provided with a sealing ring that matches the opening of the charging case body 100. When the charging case lid 200 is closed, the sealing ring can fit tightly against the edge of the opening of the charging case body 100, forming a waterproof and dustproof sealed environment. This effectively prevents external liquids and dust from entering the charging case, protecting the earphone body 300 and internal electronic components from corrosion. The sealing ring is made of food-grade silicone, which has good elasticity and aging resistance, and can maintain a stable sealing effect during long-term opening and closing. At the same time, the silicone material is soft and will not cause squeezing damage to the charging case body 100 or the earphone body 300 when closed. In addition, the cross-section of the sealing ring is designed to be semi-circular, which fits tightly with the groove of the charging case lid 200, making installation and replacement convenient and further improving the ease of maintenance of the earphone charging case.

[0046] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
