[0002] At present, wireless headphones have gradually become the mainstream device for audio playback on mobile devices. However, as a precision electronic device, headphones and headphone charging devices are often less adaptable to negative impact conditions such as moisture and impact. And due to the particularity of headphone products, the failure of one headphone may often lead to the abandonment of the entire headphone assembly. How to provide better protection for wireless headphones and corresponding headphone components is a major focus that needs to be considered for products in this field. The existing headphone boxes and related components in this field usually only have the functions of storing and charging headphones, and less consideration is given to the protection of headphones and related components. However, in actual use, improving the protection level of headphones can not only reduce users' maintenance costs and avoid waste, but also expand the use scenarios of headphones and gain greater market prospects.

[0028] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. In the present disclosure, for the sake of accurate description and easy understanding, the direction in which the earphone charging box moves along the track is defined as the longitudinal direction, and the direction perpendicular to the longitudinal direction on the horizontal plane is defined as the lateral direction.

[0029] See also Figure 1 and Figure 2 , Figure 1 A stereoscopic schematic diagram of an earphone charging box provided by an embodiment of the present disclosure is shown. Figure 2 A schematic top view of an earphone charging box provided by an embodiment of the present disclosure is shown. The earphone charging box 100 of this embodiment includes an upper shell 10 and a lower shell 20, and one side of the upper shell 10 is hingedly connected to the lower shell 20 by means of a hinge 13, and can be buckled relative to the lower shell 20. The upper shell 10 also includes an upper shell flange 30 arranged on the outer periphery of the upper shell 10. The lower shell 20 is provided with an earphone accommodating cavity 25 and a charging assembly. After the upper shell 10 and the lower shell 20 are relatively buckled, the two can relatively close the earphone accommodating cavity 25 for accommodating the earphone. The lower shell 20 also includes a mating portion 40, and in the closed box state where the upper shell 10 and the lower shell 20 are relatively closed, the upper shell flange 30 and the mating portion 40 can be mated and abutted.

[0030] It is understandable that in the present disclosure, the upper shell 10 and the lower shell 20 are buckled with each other in the closed box state, and the above embodiment describes a scheme for making the upper shell flange 30 and the matching portion 40 cooperate and abut. For example, the upper shell 10 and the lower shell 20 can each include an abutment plane, so that the two can abut each other with their respective abutment planes in the closed box state. It is also possible to set corresponding contact surfaces on the opposite sides of the upper shell 10 and the lower shell 20, and to set grooves and protrusions on their respective contact surfaces, so that the two contact surfaces can fit each other through the grooves and protrusions. The above-mentioned structure including the abutment plane and / or the contact surface can be arranged on the side of the upper shell flange 30 and the matching portion 40 facing each other, and the upper shell flange 30 and the matching portion 40 can extend outward along the circumference of the earphone box according to the needs of the actual structure to provide sufficient space.

[0031] refer to Figure 3 and Figure 4 , Figure 3 A schematic diagram of an earphone charging box provided by an embodiment of the present disclosure is shown. Figure 4The figure shows a schematic diagram of the closed box state of an earphone charging box provided by an embodiment of the present disclosure. The lower shell 20 may include a bottom shell 21 and a cover plate 23 that is buckled with the bottom shell 21, and the matching portion 40 is arranged at the periphery of the junction of the bottom shell 21 and the cover plate 23. In this embodiment, the outer side of the matching portion 40 also protrudes from the lower shell 20 along the circumferential direction to form a matching portion flange 41. The bottom shell 21 can be roughly formed into a rectangular box body with one side open, and the cover plate 23 is formed into a roughly rectangular plate covering the open opening. It can be understood that in this embodiment, the outer contour of the cover plate 23, the bottom shell 21 and the upper shell 10 matched therewith in the horizontal plane direction can be set to be roughly rectangular. However, in other embodiments, the outer contour can also be formed into other shapes such as a circle, a polygon, an inclined cut arranged at an angle to the horizontal plane, etc. In the relevant embodiments of the present disclosure, the upper shell flange 30 and the matching portion 40 arranged on the outer periphery of the upper shell are matched to increase the contact area of ​​the outer edge of the upper and lower shells in the closed box state. The enlarged joint surface of the upper shell 10 and the lower shell 20 in the closed box state can make the upper shell 10 and the lower shell 20 more stable and less likely to shake in the closed box state, and also ensures that the profile of the horizontal cross-section of the upper and lower shells can be set to various shapes without affecting the stability of the earphone box.

[0032] After the bottom shell 21 and the cover plate 23 are buckled together, a circumferential groove 27 is formed on the outer circumference of the two, and the matching portion flange 41 is at least partially accommodated in the circumferential groove 27 and circumferentially covers the connection portion between the bottom shell 21 and the cover plate 23 of the housing. The cover plate 23 and the bottom shell 21 are sealed inside, thereby defining an accommodation space, which can be used to accommodate components such as batteries, control components and charging components;

[0033] Also refer to Figure 2A recessed earphone accommodating cavity 25 is formed on the surface of the cover plate 23, which is used to at least partially accommodate wireless earphones. The earphone accommodating cavity 25 is completely closed by the bottom surface of the upper shell 10 in the closed box state. The earphone accommodating cavity 25 can be formed in accordance with the shape of the earphone, so as to facilitate the placement of the earphone, and the earphone is well limited in the closed box state to prevent the earphone from moving and colliding in the box. On one side of the earphone accommodating cavity 25, a charging positioning block 233 for positioning the earphone charging part can also be provided. The charging positioning block 233 protrudes from the upper surface of the cover plate 23 toward the upper shell 10 to limit the earphone charging part from the side. A pair of laterally protruding charging pins 231 are also provided on the side of the charging positioning block 233 to facilitate contact with the terminals of the earphone charging part for charging after the earphone is placed in the earphone accommodating cavity 25. To further facilitate the positioning of the earphone, a magnetic suction piece can also be provided inside the charging positioning block 233, which can adsorb the earphone charging part by magnetic force or the like. The cover plate 23 is also provided with a physical button 238 and a charging indicator light 236 for indicating the charging status. The physical button 238 and the charging indicator light 236 are respectively electrically connected to the control components and other components inside the earphone charging box 100, so as to realize the functions of reset and charging indication. In some embodiments, the physical button is used to trigger Bluetooth pairing, or other physical buttons specifically for Bluetooth pairing can be added. By setting the button and / or other physical buttons on the upper surface of the cover plate 23, the risk of water ingress can be further reduced by sealing the closed box, thereby simplifying the waterproof design.

[0034] Refer again Figure 3, wherein the circumferential outer contour and the circumferential inner contour of the mating portion flange 41 are both roughly formed into a rectangle with rounded corners. The outer contour of the mating portion flange 41 has a fillet radius R1, and the circumferential inner contour fillet has a radius R2. In this embodiment, R1 can be set to be smaller than R2, which allows more material to be provided at the four corners of the mating portion flange 41. It is understandable that in daily use, the earphone charging box 100 may fall, and this accidental fall is a major cause of damage to the earphone charging box 100 and the earphones therein. By providing the upper shell flange 30 protruding outward in the circumferential direction and the mating portion flange 41, when the earphone charging box 100 accidentally falls, its flange portion, especially its flange corner portion, has a high probability of first contacting the ground, so that the flange corner portion replaces the weak portion of the shell to withstand the impact of the fall. Since the mating flange 41 is a strip-shaped ring-like object, more material is provided at the corners of the mating flange 41 to enhance the structural strength of the upper shell flange 30 and the mating flange 41 at this location, thereby enhancing the durability of the earphone charging box 100. In this embodiment, in order to take into account both the structural strength and the accommodation space required for the internal components, the ratio of the radius R1 of the fillet of the outer contour of the mating flange 41 to the radius R2 of the fillet of the circumferential inner contour can be selected within a setting range of: 0.4≤R1:R2≤0.7.

[0035] See also Figure 4 , wherein the upper shell flange 30 and the matching portion flange 41 overlap each other in the closed box state, and the two have a thickness D1 after overlapping in the vertical direction, and the box body of the earphone charging box 100 has an overall thickness D2 in the vertical direction. As described above, when the earphone charging box 100 falls, by providing the upper shell flange 30 and the matching portion flange 41, it can be made to contact the ground first to avoid damage to the shell. To this end, in order to increase the probability that the upper shell flange 30 and the matching portion flange 41 touch the ground before other parts of the earphone shell, the thickness of the upper shell flange 30 and the matching portion flange 41 needs to meet certain numerical requirements relative to the overall thickness of the shell. For example, in this embodiment, it is stipulated that the ratio range of the thickness D1 between the upper surface of the upper shell flange 30 and the lower surface of the matching portion flange 41 to the thickness D2 of the earphone charging box 100 can be: 1 / 3≤D1:D2≤1 / 2.

[0036] Reference Figure 4 and Figure 5 , Figure 5The side view schematic diagram of an earphone charging box provided by the embodiment of the present disclosure is shown. The mating portion flange 41 can be formed to have substantially the same outer contour and inner contour as the upper shell flange 30 of the upper shell 10. In the closed box state, the surfaces of the upper shell flange 30 and the lower shell 20 flange relative to each other can overlap each other, so that the upper shell flange 30 and the lower shell 20 flange jointly seal the interior of the earphone charging box 100. The surfaces of the upper shell flange 30 and the lower shell 20 flange relative to each other fit each other, and a surrounding sealing area can be formed on the outer side of the earphone in the circumferential direction, thereby preventing the earphone or physical button 238 and other components inside the earphone charging box 100 from being damp or water-infiltrated when the earphone charging box 100 is affected by moisture or splashing water. In addition, the mating portion flange 41 can also cover the joint of the cover plate 23 and the bottom shell 21 in the circumferential direction, so that the gap between the cover plate 23 and the bottom shell 21 is almost sealed, preventing the risk of dampness or water infiltration of the internal electronic components, and also improving the overall aesthetics. Specifically, the joint portion at the circumferential outer edge of the cover plate 23 of the lower shell 20 and the bottom shell 21 matched therewith will produce an annular joint line around the outer periphery of the lower shell 20. The joint portion can be hidden by arranging it in the circumferential groove 27 and covering it with the matching flange 41. Thereby improving the sealing and the aesthetics at the same time. On this basis, if the matching flange 41 is set to use a non-transparent material, the joint portion can be completely hidden in appearance, and visually more integrated. Even if the matching flange 41 is set to use a transparent or translucent material, the joint portion is difficult to be observed by the user at a non-direct viewing angle due to the refraction and reflection of light by the matching material, so that it can meet the transparent design requirements and obtain the visual effect of hidden seams. Also refer to Figure 1 , the inner side of the upper shell 10 can also be formed with a positioning protrusion 11 protruding inward, and the positioning protrusion 11 is roughly a rectangular block, and its interior is hollow. The overall thickness of the positioning protrusion 11 is about 1 / 2 of the thickness of the upper shell flange 30, and its interior can be used to set a magnetic part to adsorb the magnetic part corresponding to the lower shell 20 in the closed box state, thereby facilitating the maintenance of the closed box state and enhancing the sealing effect of the earphone charging box 100. The seam is covered by a solid body, which is also conducive to the dust-proof and water-draining design. Such a structural design makes it possible to only apply glue on the inside of the shell even if multiple components are spliced ​​and combined, without the need for glue reinforcement between the mating flange 41 and the lower shell 20, that is, the limiting is directly performed through the circumferential groove.

[0037] In some embodiments, in order to increase the fitting effect between the matching flange 41 and the upper shell flange 30, a plurality of magnetic parts can be arranged along the circumferential direction. In addition, a spring part can be arranged inside the hinge 13 or at the joint of the upper shell 10 and the lower shell 20 to enhance the closing retention force of the upper shell 10 and the lower shell 20 in the closed box state, and enhance the sealing and stability. An elastic part can be sandwiched between the matching flange 41 and the upper shell flange 30. For example, an elastic annular sealing part, such as a rubber sealing ring, can be added to the edges of the opposite sides of one or both of the matching flange 41 and the upper shell flange 30. When closing the lid, the magnetic attraction provided by the magnetic attraction part after closing the lid and / or the force of the rotating shaft elastic part provided by the spring part can be used to make the matching flange 41 and the upper shell flange 30 fit together, and the elastic part forms a closed ring, so that the joint surface can have a waterproof function.

[0038] See also Figure 5 , the upper part of the cover plate 23 can protrude from the upper surface of the matching part 40 in the vertical direction to form a cover plate positioning part 237. The outer edge of the cover plate positioning part 237 can be engaged with the inner edge 301 of the upper shell 10 in the closed box state, thereby improving the sealing between the upper shell 10 and the lower shell 20, and further protecting the components in the earphone charging box 100. It can be understood that the cooperation between the outer edge of the cover plate positioning part 237 and the inner edge 301 of the upper shell 10 is intended to enhance the sealing and stability of the earphone shell in the closed box state. On the premise of meeting this need, the present disclosure does not limit the specific formation method of the sealing structure. For example, the flange of the matching part can be provided to include a step portion protruding upward, and the step portion is in shape with the inner edge of the upper shell. Or the flange of the upper shell includes a downward protrusion, which cooperates with the sealing groove formed on the upper surface of the cover plate to perform sealing, etc.

[0039] It is understandable that, in this embodiment, the periphery of the mating portion 40 protrudes from the bottom shell 21 and the cover plate 23 to form a mating portion flange 41. However, the present disclosure does not limit the specific structure of the mating portion, and it is based on its ability to cooperate with the flange of the upper shell to increase the sealing of the headphone charging box and enhance the collision protection performance of the headphone charging box. For example, the mating portion can be made to surround the lower shell as a whole on the circumferential outside without providing an outwardly protruding structure. At this time, the upper side of the mating portion can still be set to fit with the bottom side surface of the flange of the upper shell, which further increases the strength of the structure without affecting the sealing.

[0040] In this embodiment, the upper shell 10 and the mating part 40 can be set to be transparent or translucent. This transparent structure can facilitate the user to observe the inside of the earphone charging box 100, confirm the charging status or whether the earphones are stored therein, etc. Further, in this embodiment, after the upper shell 10 and the mating part 40 are set to be transparent, the internal state can be presented to the outside through the lens structure formed by the transparent material at the corners due to its structural shape. For example Figure 4 The inner and outer contours of the upper shell 10 are also shown in a partial cross-sectional view. The outer contour of the upper shell is roughly arc-shaped, that is, it has an outer contour fillet A1, and correspondingly, its inner contour is also arc-shaped and has an inner contour fillet A2. The inner contour fillet A2 is aligned with the outer contour fillet A1 along the optical path, and can have different radii, for example, A1>A2, thereby forming a convex lens-like effect. With the help of the convex lens structure and the similar structure formed at the fillets of the aforementioned upper shell flange 30 and the mating portion flange 41, when it is impossible to determine whether the earphone is stored in the earphone charging box 100, the user can easily use the refraction and reflection of the transparent part of the earphone shell to clearly observe the situation in the earphone accommodating cavity from multiple angles. For example, when the earphone charging box 100 charges the earphone, the light of the charging indicator light 236 emitted by it will be transmitted to the outside of the earphone charging box 100 through the transparent part. At this time, even if part of the earphone charging box 100 is made of opaque material, or the earphone charging box 100 is inverted so that the charging indicator light 236 cannot be directly seen, the user can still confirm the charging status with the help of the transparent upper shell flange 30 and the matching part flange 41 to refract and reflect the indicator light. It can be understood that although this embodiment only cites the scheme of setting the upper shell 10, the upper shell flange 30 and the matching part 40 to be transparent, the present disclosure is not limited in this regard. For example, under the premise of meeting the observation needs, the various components of the earphone charging box 100 can also be set to be transparent or translucent separately, partially or completely.

[0041] In addition, in this embodiment, the outer contour corners of the lower shell can also have a curvature, that is, it has an outer contour fillet A3. The curvature of the outer contour of the upper shell can be greater than the curvature of the outer contour of the lower shell. For example, the radius of the outer contour fillet A1 of the upper shell 10 can be set to have a larger radius than the outer contour fillet A3 of the lower shell 20. In addition to making it easier to distinguish the front and back of the earphone charging box 100 by touch, this setting also provides a smaller fillet of the lower shell 20 to provide a larger accommodation space to accommodate internal charging components and batteries.

[0042] In some embodiments, the inner contour fillet A2 and other parts of the inner surface of the upper shell can be formed as reverse protrusions, that is, they protrude toward the inner side of the upper shell, so that a convex lens effect can be formed when the outer surface is flat. The convex lens or its equivalent structure formed by the above-mentioned various structures can be focused on a part or the whole of the earphone body, thereby forming a magnifying effect when observed from the outside of the earphone box. It can be understood that in other embodiments, the convex lens and its equivalent structure of the transparent part of the earphone box can be set to one or more. Each one or more of them corresponds to the corresponding key area of ​​the magnified product, such as the mic structure, the mesh surface, etc., so that the state of the key areas inside the earphone box can be quickly observed without opening the earphone box, including whether there is dirt or foreign matter, etc., so as to deal with it in time to avoid failures. In addition, the one or more convex lens structures can also be used to highlight the internal design of the product, enhance the attractiveness of the product, and improve the appearance of the product.

[0043] See also Figure 6 , Figure 6 A stereoscopic schematic diagram of an earphone assembly provided by an embodiment of the present disclosure is shown. The earphone assembly 200 of this embodiment may include an earphone charging box 100 according to some embodiments of the present disclosure, and an earphone 60 disposed in the earphone charging box 100. In this embodiment, a pair of exemplary earphones 60 are disposed on the upper side of the cover 23 of the earphone charging box 100. The speaker portion 63 of the earphone is matched with the shape of the earphone accommodating cavity 25, and the charging portion 61 of the earphone is adjacent to the charging positioning block 233 on the cover 23. As described above, the charging pin 231 on the charging positioning block 233 can be docked with the terminal on the earphone charging portion 61 at this time, so as to charge the earphone 60. When the upper shell 10 is closed and covered relative to the lower shell 20, and the earphone charging box 100 is in a closed box state, the sealing structure composed of the upper shell flange 30 and the matching portion 40 of the earphone charging box 100 can provide good waterproof protection for the earphone 60 and other internal components, and can prevent accidental situations such as falling and collision from causing damage to the earphone 60 and internal components, greatly improving the safety of the earphone assembly 200.
