Description

[0001] This application claims priority to Chinese Patent Application No. 202311131565.9, filed on September 1, 2023, entitled "Earphone Case and Earphone Case Assembly", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of headphones, and more particularly to a headphone case and headphone case assembly. Background Technology

[0003] With the continuous development of electronic technology and the increasing demand for portability, wireless earphones are gaining popularity. Typically, wireless earphones are used with a charging case, which stores and charges the earphones. The charging case has a first charging pin group and a second charging pin group. The first charging pin group is paired with the left earphone, and the second charging pin group is paired with the right earphone. If either the first or second charging pin group malfunctions, either the left or right earphone will not be able to charge. Utility Model Content

[0004] This application provides an earphone case and an earphone case assembly.

[0005] Firstly, this application provides an earphone case. The earphone case includes a case body, a first charging pin group, and a second charging pin group. The first and second charging pin groups are disposed on the case body and are arranged at intervals along a first direction. The first charging pin group is used to charge a first earphone, and the second charging pin group is used to charge a second earphone. The first charging pin group includes a first positive charging pin and a first negative charging pin, which are arranged at intervals along a second direction, which is different from the first direction. The second charging pin group includes a second positive charging pin and a second negative charging pin, which are arranged at intervals along a third direction, which is different from the first direction. The connection between the first positive charging pin and the second positive charging pin is a first connection, and the connection between the first negative charging pin and the second negative charging pin is a second connection. The first and second connections are intersecting.

[0006] It's understandable that the arrangement directions of the first positive and negative charging pins in the first charging slot and the second positive and negative charging pins in the second charging slot are reversed. This way, when the earphone case is used to charge the first and second earphones, the first earphone can be charged in either the first or second charging slot. In other words, there's no need to distinguish between left and right earphones when charging the first and second earphones. For example, the first positive and negative charging pins can charge the first earphone. When the first earphone is flipped and connected to the second charging pin group, the directions of the second positive and negative charging pins relative to the first earphone can be the same as the directions of the first positive and negative charging pins relative to the first earphone. Therefore, the second charging pin group can also charge the first earphone. The same applies to charging the second earphone. Thus, when the earphone case is charging the first and second earphones, if one of the first or second charging pin groups fails, the first and second earphones can be charged through the other intact charging pin group.

[0007] In one possible implementation, the distance between the second positive charging pin and the first negative charging pin is less than the distance between the second negative charging pin and the first positive charging pin.

[0008] Understandably, when the first and second earbuds are charging, the first earbud can rotate a certain angle away from the second charging pin group. The second earbud can also rotate a certain angle away from the first charging pin group. In this way, while the distance between the first positive charging pin and the second negative charging pin remains constant, the distance of the earbud case in the first direction can be reduced.

[0009] In one possible implementation, the distance between the first positive charging pin and the first negative charging pin is equal to the distance between the second positive charging pin and the second negative charging pin.

[0010] In one possible implementation, the first positive charging pin and the second negative charging pin are symmetrical about a plane of symmetry, which is perpendicular to a first direction.

[0011] Understandably, when the first and second earbuds are charging in the charging case, they can be arranged symmetrically for easy access by the user.

[0012] In one possible implementation, the case includes an earphone bracket and a shell, with the earphone bracket connected to the inside of the shell, forming an accommodating space. The earphone case also includes a battery disposed within the accommodating space. The earphone bracket has a first charging slot and a second charging slot, spaced apart from each other. A first positive charging pin and a first negative charging pin are located on the earphone bracket, with one end of each pin protruding from the first charging slot and the other ends located within the accommodating space, electrically connected to the battery. A second positive charging pin and a second negative charging pin are located on the earphone bracket, with one end of each pin protruding from the second charging slot and the other ends located within the accommodating space, electrically connected to the battery.

[0013] In one possible implementation, the outer casing has a charging channel that connects to the accommodating space. The earphone case includes a USB male connector, with the USB male connector and battery spaced apart. Part of the USB male connector is located within the accommodating space, and part is located within the charging channel. The USB male connector is electrically connected to a first positive charging pin, a first negative charging pin, a second positive charging pin, and a second negative charging pin. This allows the earphone case to be charged using a USB wired charging method.

[0014] In one possible implementation, the earphone case includes a speaker disposed within an accommodating space, with the speaker, USB male connector, and battery spaced apart from each other. A gap exists between the USB male connector and the wall of the charging channel, through which sound emitted by the speaker propagates to the outside of the case.

[0015] Understandably, the speaker output and the headphone case charging can share the same charging channel, which avoids the need to make additional holes in the outer shell for speaker output, reducing a process and saving on the manufacturing cost of the headphone case.

[0016] In one possible implementation, the earphone case includes a wireless charging coil located within an accommodating space, with the wireless charging coil and battery spaced apart from each other. The wireless charging coil is electrically connected to a first positive charging pin, a first negative charging pin, a second positive charging pin, and a second negative charging pin. This allows the earphone case to be charged wirelessly.

[0017] In one possible implementation, the earphone case further includes a protective cover and a first hinge, the protective cover being rotatably connected to one end of the outer shell. The middle portion of the first hinge is fixed to the outer shell, and the protective cover is rotatably connected to a first end and a second end of the first hinge, with the middle portion of the first hinge connecting between the first end and the second end of the first hinge.

[0018] Understandably, using the outer casing to fix the first pivot eliminates the need for an additional fixing structure, and the connection between the first pivot and the outer casing is stronger, making the assembly process simpler.

[0019] In one possible implementation, the housing includes a body portion and a protrusion, the protrusion being positioned on the surface of the body portion facing the protective cover, and the earphone bracket being connected to the inner side of the body portion. The middle portion of the first pivot is fixed to the protrusion.

[0020] Understandably, the protrusion extends from the surface of the main body facing the protective cover, and the middle of the first rotating shaft is fixed to the protrusion. That is, the first rotating shaft is fixedly connected to the side of the main body closer to the protective cover. Compared to the technical solution of fixing the first rotating shaft to the side of the main body away from the protective cover, this solution can save internal space of the housing and avoid the first rotating shaft and the corresponding fixing structure occupying internal space of the housing.

[0021] In one possible implementation, the headphone stand is tilted relative to the side wall of the housing.

[0022] It is understandable that when the first and second earbuds are located inside the earphone case, they are positioned on the earphone stand. When the earphone stand is tilted relative to the side wall of the outer casing, the first and second earbuds can also be tilted relative to the side wall of the outer casing. This reduces the height of the earbuds within the earphone case, thus helping to reduce the overall height of the earphone case.

[0023] Secondly, this application provides an earphone case assembly. The earphone case assembly includes earphones and an earphone case, with the earphones disposed inside the earphone case. It is understood that the earphone case can be used to protect the earphones. Attached Figure Description

[0061] The embodiments of this application are described below with reference to the accompanying drawings.

[0062] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after the connection. It should be understood that when component A is fixedly connected to component C via component B, changes in the relative positional relationship due to deformation of components A, B, and C are permissible. The integrated structure obtained by the two components through a one-piece molding process means that during the formation of one of the two components, that component is connected to the other component, without requiring further processing (such as bonding, welding, snap-fit ​​connections, or screw connections) to connect the two components.

[0063] The directional terms mentioned in the embodiments of this application, such as "upper", "lower", "side", etc., are only for reference to the direction of the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0064] The term "multiple" refers to at least two. The term "more than" includes the stated number. The term "and / or" describes a relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0065] Figure 1 This is a schematic diagram of one embodiment of the headphone case assembly 1000 provided in this application. Figure 2a yes Figure 1 The diagram shows a structural schematic of one embodiment of the headphone case 100 in its closed state. Figure 2b yes Figure 1 The diagram shows a structural schematic of one embodiment of the headphone case 100 in the open state.

[0066] like Figure 1 , Figure 2a and Figure 2b As shown, the earphone case assembly 1000 may include an earphone case 100 and earphones 200. The earphone case 100 can be used to store wireless earphones and charge them. The earphones can be in-ear earphones, semi-open earphones, or open earphones 200. This application uses clip-on wireless earphones as an example for description.

[0067] For example, the earphone case 100 can simultaneously store and charge two earphones 200. For ease of description, these two earphones 200 are referred to as the first earphone and the second earphone (the first earphone is...). Figure 1 The left earphone in the middle, the second earphone is Figure 1 (Right earphone).

[0068] In some implementations, the first and second earphones can be identical, meaning that the shape and internal component arrangement of the first and second earphones can be the same.

[0069] The earphone case 100 may have a storage space 40 for accommodating earphones 200. The earphone case 100 may include a closed state (e.g., Figure 2a (as shown) and open state (as shown) Figure 2b (As shown). When the earphone case 100 is in the open state, the storage space 40 is exposed. When the earphone 200 is inside the earphone case 100, the earphone 200 inside the earphone case 100 can be displayed, and the user can take out the earphone 200, or the user can place the earphone 200 in the storage space 40.

[0070] The headphone case 100 can be a vertical opening headphone case or a sliding opening headphone case, etc. This application uses the vertical opening headphone case 100 as an example for introduction.

[0071] For ease of description, the width direction of the headphone case 100 is defined as the X-axis, the thickness direction of the headphone case 100 is defined as the Y-axis, and the height direction of the headphone case 100 is defined as the Z-axis.

[0072] In some implementations, the width of the earphone case 100 is W, the thickness of the earphone case 100 is D, and the height of the earphone case 100 is H, with the relationship between the three satisfying W>H>D.

[0073] Figure 3 yes Figure 2a An exploded view of one embodiment of the headphone case 100 shown.

[0074] like Figure 3 As shown, the earphone case 100 may include a charging case 10, a protective cover 20, and a rotating assembly 30. The rotating assembly 30 is rotatably connected to the charging case 10. The rotating assembly 30 is rotatably connected to the protective cover 20. The charging case 10 and the protective cover 20 can rotate relative to each other through the rotating assembly 30, thereby allowing the earphone case 100 to switch between a closed state and an open state.

[0075] Figure 4 yes Figure 3 The diagram shows a structural schematic of one embodiment of the charging box 10 shown. Figure 5 yes Figure 4 An exploded view of one embodiment of the charging case 10 shown.

[0076] like Figure 4 and Figure 5 As shown, the charging case 10 may include a case body 1, a first charging pin group 2, a second charging pin group 3, a battery module 4, a motherboard 5, a charging coil module 6, a first bracket 7, an antenna 8, a speaker 9, a magnet module 19 (structure within the dashed box), and a first flexible circuit board 18. The first charging pin group 2 is disposed on the case body 1. The battery module 4, motherboard 5, charging coil module 6, first bracket 7, antenna 8, speaker 9, magnet 19, and first flexible circuit board 18 may be disposed inside the case body 1. The first charging pin group 2 can be used to charge a first earphone. The second charging pin group 3 can be used to charge a second earphone. Exemplarily, the case body 1 may include an earphone bracket 11 and a shell 12. The earphone bracket 11 is connected to the inside of the shell 12. Exemplarily, the first charging pin group 2 includes a first positive charging pin 21 and a first negative charging pin 22. The second charging pin group 3 includes a second positive charging pin 31 and a second negative charging pin 32.

[0077] Figure 6 yes Figure 5 The diagram shows a structural schematic of one embodiment of the headphone stand 11. Figure 7 yes Figure 6 The diagram shows the structure of the headphone stand 11 from another angle.

[0078] like Figure 6 and Figure 7 As shown, the headphone holder 11 has a top surface 111 and a bottom surface 112. The top surface 111 and the bottom surface 112 are disposed opposite to each other. The headphone holder 11 may have a first charging slot 13 and a second charging slot 14. The opening of the first charging slot 13 and the opening of the second charging slot 14 may be located on the top surface 111 of the headphone holder 11. The first charging slot 13 and the second charging slot 14 may be arranged at intervals along a first direction. It is understood that the first charging slot 13 and the second charging slot 14 can be used to accommodate headphones 200. Figure 6 The illustration uses an example where the first direction is parallel to the X-axis. In other embodiments, the first direction can be any direction in the XY plane; for example, the first direction can be at an angle to the X-axis.

[0079] The headphone stand 11 may be provided with a first charging port 115, a second charging port 116, a third charging port 117, and a fourth charging port 118. The first charging port 115, the second charging port 116, the third charging port 117, and the fourth charging port 118 connect the top surface 111 and the bottom surface 112 of the headphone stand 11. For example, the first charging port 115 and the second charging port 116 are located within the first charging slot 13 and are spaced apart. The third charging port 117 and the fourth charging port 118 are located within the second charging slot 14 and are also spaced apart.

[0080] In some embodiments, the first charging slot 13 and the second charging slot 14 may be symmetrical about the symmetry plane S. The first direction is perpendicular to the symmetry plane S. Figure 6 The diagram is illustrated using the example of a plane of symmetry S parallel to the YZ plane.

[0081] In some embodiments, the opening of the first charging slot 13 may have a first major axis L1 (the first major axis L1 is a virtual line segment, Figure 6 (Illustrated schematically using a dashed line), the first major axis L1 is the line connecting the two points furthest apart on the opening of the first charging slot 13. The projection of the first major axis L1 onto the XY plane forms an angle with the Y-axis direction. For example, the angle can be 2°, 5°, or 8°.

[0082] In some embodiments, the opening of the second charging slot 14 may have a second major axis L2 (the second major axis L2 is a virtual line segment). Figure 6(Illustrated schematically using a dashed line), the second major axis L2 is the line connecting the two points furthest apart on the opening of the second charging slot 14. The projection of the second major axis L2 onto the XY plane forms an angle with the Y-axis direction. For example, the angle can be 2°, 5°, or 8°.

[0083] In some implementations, the first charging port 115 and the fourth charging port 118 may be symmetrical about the plane of symmetry S.

[0084] In some embodiments, the second charging port 116 and the third charging port 117 may be symmetrical about the plane of symmetry S.

[0085] The headphone holder 11 may also have a first receiving slot 23 and a second receiving slot 24. The first receiving slot 23 and the second receiving slot 24 may be arranged at intervals along a first direction. The first receiving slot 23 and the second receiving slot 24 may also be used to receive headphones 200. For example, when the first and second headphones are clip-on headphones 200, the first receiving slot 23 may cooperate with the first charging slot 13 to receive the first headphones. The second receiving slot 24 may cooperate with the second charging slot 14 to receive the second headphones.

[0086] For example, the first receiving slot 23, the second receiving slot 24, the first charging slot 13, and the second charging slot 14 are arranged at intervals. The first receiving slot 23 may be located on the side of the first charging slot 13 away from the second charging slot 14. The second receiving slot 24 may be located on the side of the second charging slot 14 away from the first charging slot 13. That is, the first charging slot 13 and the second charging slot 14 may be located between the first receiving slot 23 and the second receiving slot 24.

[0087] In other embodiments, the first receiving slot 23 may be disposed on the side of the first charging slot 13 near the second charging slot 14. The second receiving slot 24 may be disposed on the side of the second charging slot 14 near the first charging slot 13. The first receiving slot 23 and the second receiving slot 24 may be located between the first charging slot 13 and the second charging slot 14.

[0088] In some embodiments, the first receiving groove 23 and the second receiving groove 24 may be symmetrical about the plane of symmetry S.

[0089] The headphone holder 11 may also have a first groove 1121, a second groove 1122, a third groove 1123, and a fourth groove 1124 spaced apart. The openings of the first groove 1121, the second groove 1122, the third groove 1123, and the fourth groove 1124 may be located on the bottom surface 112 of the headphone holder 11.

[0090] In some embodiments, the headphone holder 11 may further include a first positioning post 113. The first positioning post 113 may be adjacent to and spaced apart from the first charging port 115. The first positioning post 113 is located on one side of the bottom surface 112 of the headphone holder 11.

[0091] For example, there may be two first positioning posts 113. The two first positioning posts 113 may be arranged along a first direction and located on both sides of the first charging hole 115.

[0092] In some embodiments, the headphone holder 11 may further include a second positioning post 114. The second positioning post 114 may be adjacent to and spaced apart from the second charging port 116. The headphone holder 11 may further include a third positioning post 25. The third positioning post 25 may be adjacent to and spaced apart from the third charging port 117. The headphone holder 11 may further include a fourth positioning post 26. The fourth positioning post 26 may be adjacent to and spaced apart from the fourth charging port 118. The arrangement of the second positioning post 114, the third positioning post 25, and the fourth positioning post 26 can refer to the arrangement of the first positioning post 113, and will not be repeated here.

[0093] Figure 8 yes Figure 5 The diagram shows a partial assembly of the charging box 10.

[0094] like Figure 8 The first charging pin group 2 and the second charging pin group 3 are disposed on the earphone bracket 11. The first charging pin group 2 and the second charging pin group 3 can be arranged at intervals along a first direction. For example, one end of the first positive charging pin 21 and one end of the first negative charging pin 22 are exposed in the first charging slot 13. One end of the second positive charging pin 31 and one end of the second negative charging pin 32 are exposed in the second charging slot 14.

[0095] For example, the first positive charging pin 21 can be disposed in the first charging port 115. The first negative charging pin 22 can be disposed in the second charging port 116. The second positive charging pin 31 can be disposed in the third charging port 117. The second negative charging pin 32 can be disposed in the fourth charging port 118.

[0096] In some embodiments, the first positive charging pin 21 and the first negative charging pin 22 may be arranged at intervals along a second direction. The second direction is different from the first direction.

[0097] In some embodiments, the second positive charging pin 31 and the second negative charging pin 32 may be arranged at intervals along a third direction. This third direction differs from the first direction. It is understood that the third direction and the second direction may be the same or different. Figure 8 The third direction and the second direction shown are different.

[0098] In some embodiments, the line connecting the first positive charging pin 21 and the first negative charging pin 22 may be set at an angle to the plane of symmetry S. Similarly, the line connecting the second positive charging pin 31 and the second negative charging pin 32 may be set at an angle to the plane of symmetry S. In other embodiments, the line connecting the first positive charging pin 21 and the first negative charging pin 22 may be parallel to the plane of symmetry S.

[0099] Figure 9 yes Figure 8 The diagram shows a cross-sectional view of one embodiment of the structure at section line AA.

[0100] like Figure 8 and Figure 9 As shown, the first positive charging pin 21 may include a first end 211 and a second end 212 spaced apart along its length. The first charging pin is disposed within the first charging hole 115, with the first end 211 of the first positive charging pin 21 protruding from the first charging slot 13 and the second end 212 protruding from the bottom surface 112 of the earphone bracket 11. The arrangement of the first negative charging pin 22 and the second charging hole 116, the arrangement of the second positive charging pin 31 and the third charging hole 117, and the arrangement of the second negative charging pin 32 and the fourth charging hole 118 can refer to the arrangement of the first positive charging pin 21 and the first charging hole 115, and will not be repeated here.

[0101] The line connecting the first positive charging pin 21 and the second positive charging pin 31 is the first connection line. The line connecting the first negative charging pin 22 and the second negative charging pin 32 is the second connection line. The first connection line and the second connection line are intersecting. It should be noted that the intersecting arrangement here means that the projections of the first connection line and the second connection line on the XY plane intersect. Spatially, the first connection line and the second connection line may or may not intersect.

[0102] It is understandable that the arrangement directions of the first positive charging pin 21 and the first negative charging pin 22 in the first charging slot 13 are opposite to those of the arrangement directions of the second positive charging pin 31 and the second negative charging pin 32 in the second charging slot 14. This way, when the earphone case 100 is used to charge the first and second earphones, the first earphone can be charged in the first charging slot 13 or rotated to charge in the second charging slot 14 (for example, the first earphone can be charged in the first charging slot, or rotated 180° in the XY plane to charge in the second charging slot). The second earphone works similarly. In other words, when charging the first and second earphones, there is no need to distinguish between left and right ears; the first positive charging pin 21 and the first negative charging pin 22 can charge either the first or the second earphone. Similarly, the second positive charging pin 31 and the second negative charging pin 32 can charge either the first or the second earphone. This provides a better user experience.

[0103] For example, the line connecting the center of the first positive charging pin 21 and the center of the second positive charging pin 31 is the first connection line. The line connecting the center of the first negative charging pin 22 and the center of the second negative charging pin 32 is the second connection line.

[0104] In some embodiments, the distance between the first positive charging pin 21 and the first negative charging pin 22 may be equal to the distance between the second positive charging pin 31 and the second negative charging pin 32.

[0105] In some embodiments, the first positive charging pin 21 and the second negative charging pin 32 may be symmetrical about the plane of symmetry S. The first negative charging pin 22 and the second positive charging pin 31 may be symmetrical about the plane of symmetry S.

[0106] In some embodiments, the distance between the second positive charging pin 31 and the first negative charging pin 22 can be less than the distance between the second negative charging pin 32 and the first positive charging pin 21. The first positive charging pin 21, the first negative charging pin 22, the second positive charging pin 31, and the second negative charging pin 32 can be arranged in a figure-eight pattern. That is, the first connecting line and the second connecting line can form a figure-eight pattern.

[0107] In some implementations, the projection of the first connecting line onto the XY plane is called the first projection. The first projection may be set at an angle to the Y-axis. For example, the angle may be 2°, 5°, or 8°.

[0108] In some embodiments, the projection of the first connecting line onto the YZ plane is a second projection. The second projection can be set at an angle to the Y-axis. For example, the angle can be 5°, 10°, 15°, 20°, etc. When the first earphone is charging, it can be placed at an angle relative to the XY plane, which can reduce the height of the charging case 10.

[0109] Figure 10 yes Figure 5 The diagram shows a partial assembly of the charging box 10.

[0110] like Figure 5 and Figure 10 As shown, magnet 19 may include a first magnet 191, a second magnet 192, a third magnet 193, and a fourth magnet 194. The first magnet 191 is disposed in the first groove 1121. The second magnet 192 is disposed in the second groove 1122. The third magnet 193 is disposed in the third groove 1123. The fourth magnet 194 is disposed in the fourth groove 1124. For example, the first magnet 191, the second magnet 192, the third magnet 193, and the fourth magnet 194 may be arranged at intervals along a first direction.

[0111] Magnet 19 may also include a first attracting magnet 19. When the earphone case 100 switches from an open state to a closed state, the first attracting magnet 19 can be used to help the protective cover 20 reset.

[0112] Figure 11 yes Figure 5 The diagram shows a partial assembly of the charging box 10.

[0113] like Figure 11 As shown, the first flexible circuit board 18 can be fixedly connected to the bottom surface 112 of the earphone bracket 11. The first positive charging pin 21, the first negative charging pin 22, the second positive charging pin 31, and the second negative charging pin 32 are all connected to the first flexible circuit board 18 and are electrically connected to it. The first flexible circuit board 18 can be used to transmit electrical signals to the first positive charging pin 21, the first negative charging pin 22, the second positive charging pin 31, and the second negative charging pin 32. For example, when the first charging pin is located in the first charging hole 115, the second end 212 of the first positive charging pin 21 protrudes from the bottom surface 112 of the earphone bracket 11. The first flexible circuit board 18 has a first electrical connection portion 182. The first electrical connection portion 182 is used to transmit electrical signals to the first positive charging pin 21. The second end 212 of the first positive charging pin 21 can be connected to the first electrical connection portion 182 of the first flexible circuit board 18 and is electrically connected to it.

[0114] In some embodiments, the first flexible circuit board 18 is provided with a clearance hole 181. When the flexible circuit is fixedly connected to the bottom surface 112 of the earphone bracket 11, the positioning post is located within the clearance hole 181. Thus, the first positioning post 113 can be used to assist in positioning the first flexible circuit board 18 during installation, helping the first positive charging pin 21 to quickly position itself to connect with the first flexible circuit board 18. Simultaneously, it can reduce the risk of displacement of the first flexible circuit board 18, which could lead to a break in the connection between the first positive charging pin 21 and the first flexible circuit board 18.

[0115] Figure 12 yes Figure 5 The diagram shows a structural schematic of one embodiment of the outer casing 12. Figure 13 yes Figure 12 The diagram shows the structure of the outer casing 12 from another angle.

[0116] like Figure 12 and Figure 13 As shown, the housing 12 may include a body portion 121 and a protrusion 122. The protrusion 122 may be connected to the top surface 1219 of the body portion 121. Exemplarily, the protrusion 122 may be integrally formed with the body portion 121. For example, the housing 12 may be formed into an integral structural component by injection molding.

[0117] For example, the body portion 121 may include a first sidewall 1211, a second sidewall 1212, a third sidewall 1213, a fourth sidewall 1214, and a bottom wall 1215. The first sidewall 1211 and the second sidewall 1212 are opposite to each other and spaced apart, and the third sidewall 1213 and the fourth sidewall 1214 are opposite to each other and spaced apart. The third sidewall 1213 is connected between the first sidewall 1211 and the second sidewall 1212. The fourth sidewall 1214 is connected between the first sidewall 1211 and the second sidewall 1212. The first sidewall 1211 includes a top surface and a bottom surface that are opposite to each other. The second sidewall 1212 includes a top surface and a bottom surface that are opposite to each other. The third sidewall 1213 includes a top surface and a bottom surface that are opposite to each other. The fourth sidewall 1214 includes a top surface and a bottom surface that are opposite to each other. The bottom wall 1215 is connected to the bottom surfaces of the first side wall 1211, the second side wall 1212, the third side wall 1213, and the fourth side wall 1214. The first side wall 1211, the second side wall 1212, the third side wall 1213, the fourth side wall 1214, and the bottom wall 1215 can form a first groove 1121. The protrusion 122 can be connected to the top surface of the second side wall 1212. The top surfaces of the first side wall 1211, the second side wall 1212, the third side wall 1213, and the fourth side wall 1214 constitute the top surface 1219 of the body portion 121.

[0118] The outer casing 12 may have a first through hole 123, a second through hole 124, and a charging channel 125. The first through hole 123, the second through hole 124, and the charging channel 125 are all connected to the first groove 1121. The first through hole 123, the second through hole 124, and the charging channel 125 are spaced apart from each other. For example, the first through hole 123 may be located on the first sidewall 1211 and connected to the first groove 1121. The second through hole 124 may be located on the third sidewall 1213 and connected to the first groove 1121. The charging channel 125 may be located on the bottom wall 1215 and connected to the first groove 1121.

[0119] The protrusion 122 may be provided with a first rotating hole 1221 and a second rotating hole 1222. The first rotating hole 1221 and the second rotating hole 1222 are spaced apart along the Z-axis. For example, the length direction of the first rotating hole 1221 can be a first direction. The length direction of the second rotating hole 1222 can also be the first direction.

[0120] In some embodiments, the third sidewall 1213, the fourth sidewall 1214, and the bottom wall 1215 may be curved.

[0121] In some embodiments, the first sidewall 1211, the second sidewall 1212, the third sidewall 1213, the fourth sidewall 1214, and the bottom wall 1215 can be integrally formed structural components.

[0122] Figure 14 yes Figure 5 An exploded view of one embodiment of the battery module 4 shown.

[0123] like Figure 14 As shown, the battery module 4 may include a battery box 41 and a battery 42. The battery 42 is disposed inside the battery box 41. The battery box 41 is used to hold the battery 42 and protects the battery 42. For example, the battery box 41 may include a frame 411 and a cover 412. The cover 412 is connected to the frame 411. The frame 411 and the cover 412 enclose a first space 43. The battery 42 is located within the first space 43.

[0124] In some embodiments, the frame 411 of the battery box 41 can be made of plastic. This makes the battery box 41 lighter.

[0125] In some embodiments, the cover 412 of the battery box 41 can be made of stainless steel. When the battery 42 catches fire, the stainless steel cover 412 can help to block the fire.

[0126] In other embodiments, the battery box 41 may also exclude the cover plate 412.

[0127] Figure 15 yes Figure 4 The charging case 10 shown is a partial cross-sectional view of one embodiment at section line BB.

[0128] like Figure 15 As shown, the earphone bracket 11 can be connected to the inside of the housing 12, and the earphone bracket 11 and the housing 12 can enclose an accommodating space 130. Exemplarily, the earphone bracket 11 can be connected to the inside of the main body 121. The earphone bracket 11 and the main body 121 can enclose an accommodating space 130. The first magnet 191, the second magnet 192, the third magnet 193, the fourth magnet 194, the first flexible circuit board 18, the main board 5, and the battery module 4 can all be disposed within the accommodating space 130. The first flexible circuit board 18 is connected to the main board 5 and electrically connected to the main board 5. The battery module 4 is connected to the main board 5 and electrically connected to the main board 5. Thus, the current from the battery module 4 can be conducted through the main board 5 and the first flexible circuit board 18 to the charging pin, thereby charging the earphone 200.

[0129] For example, the first charging slot 13 and the second charging slot 14 are spaced apart from the accommodating space 130.

[0130] like Figure 8 , Figure 9 and Figure 15As shown, one end of the first positive charging pin 21 and one end of the first negative charging pin 22 protrude from the first charging slot 13, while the other ends of the first positive charging pin 21 and the first negative charging pin 22 are located within the accommodating space 130 and are electrically connected to the battery 42. One end of the second positive charging pin 31 and one end of the second negative charging pin 32 protrude from the second charging slot 14, while the other ends of the second positive charging pin 31 and the second negative charging pin 32 are located within the accommodating space 130 and are electrically connected to the battery 42.

[0131] In some embodiments, the first positive charging pin 21, the first negative charging pin 22, the second positive charging pin 31, and the second negative charging pin 32 can be connected to the first flexible circuit board 18, and are electrically connected to the first flexible circuit board 18. The first positive charging pin 21, the first negative charging pin 22, the second positive charging pin 31, and the second negative charging pin 32 can be electrically connected to the battery 42 through the first flexible circuit board 18.

[0132] For example, along the Z-axis, a first magnet 191 and a first charging slot 13 are disposed opposite each other. A second magnet 192 and a second charging slot 14 are disposed opposite each other. A third magnet 193 is located between the first charging slot 13 and a first receiving slot 23. A fourth magnet 194 may be located between the second charging slot 14 and the second receiving slot 24. It is understood that the first magnet 191 and the third magnet 193 can be used to cooperate with the magnets inside the first earphone, helping the first earphone to quickly position itself within the first charging slot 13 and the first receiving slot 23 when placed in the earphone case. The second magnet 192 and the fourth magnet 194 can be used to cooperate with the magnets inside the second earphone, helping the second earphone to quickly position itself within the second charging slot 14 and the second receiving slot 24 when placed in the earphone case.

[0133] For example, along the Z-axis, the motherboard 5, battery module 4, and headphone bracket 11 are stacked. The battery module 4 is located between the headphone bracket 11 and the motherboard 5. The motherboard 5 can be fixedly connected to the side of the battery box 41 away from the headphone bracket 11.

[0134] In some embodiments, the charging case 10 may further include a button module 17. The button module 17 may be fixed to the body portion 121. For example, the button module 17 may be partially located within the second through hole 124. One end of the button module 17 may protrude from the charging case 10 through the second through hole 124, and the other end may protrude from the receiving space 130. The button module 17 may be connected to the second electrical connection portion 183 of the first flexible circuit board 18, and is electrically connected to the second electrical connection portion 183 of the first flexible circuit board 18.

[0135] In some implementations, the button module 17 can be connected to the pairing switch of the earphone case, and the user can put the earphone case into Bluetooth pairing mode by pressing the button module 17.

[0136] Figure 16 yes Figure 5 The diagram shows a structural schematic of one embodiment of the first support 7 shown.

[0137] like Figure 16 As shown, the first support 7 includes a top surface 71 and a bottom surface 72. The first support 7 is provided with a first through hole 73, which connects the top surface 71 and the bottom surface 72 of the first support 7. The first support 7 may also be provided with a fifth groove 74, the opening of which is located on the top surface 71 of the first support 7. The fifth groove 74 and the first through hole 73 are spaced apart.

[0138] Figure 17 yes Figure 4 The charging case 10 shown is a partial cross-sectional view of one embodiment at section line BB. Figure 18 yes Figure 4 The charging case 10 shown is a partial cross-sectional view of one embodiment at section line CC.

[0139] like Figure 17 and Figure 18 As shown, the first bracket 7 is located within the accommodating space 130. Exemplarily, the first bracket 7 is fixed to the side of the motherboard 5 away from the battery module 4. Along the Z-axis, the first through hole 73 of the first bracket 7 and the charging channel 125 are opposite to each other and communicate with each other.

[0140] The motherboard 5 may include a circuit board 51 and electronic components 52 disposed on the circuit board 51. The circuit board 51 may be fixed to the battery box 41. The circuit board 51 may serve as a carrier for electronic components. Exemplarily, the electronic components may be active devices such as chips, or passive devices such as capacitors, inductors, and resistors. It is understood that the electronic components 52 can be selected and combined in different types and quantities to enable the motherboard 5 to have specific functions. Those skilled in the art can select the type and quantity of electronic components according to actual needs, and this application does not limit this selection.

[0141] Electronic device 52 may include a USB male connector 531. The USB male connector 531 is located within the accommodating space 130. The USB male connector 531 and battery 42 are spaced apart. Exemplarily, the USB male connector 531 is fixedly connected to the side of circuit board 51 away from battery module 4 and electrically connected to circuit board 51. The USB male connector 531 may be partially located within the accommodating space 130, and another portion within the first through-hole 73 and charging channel 125. The USB male connector 531 may protrude from the outer casing 12 of the charging case 10 through the charging channel 125. The USB male connector 531 can be used to connect an external USB charging cable.

[0142] The USB male connector 531 is electrically connected to the first positive charging pin 21, the first negative charging pin 22, the second positive charging pin 31, and the second negative charging pin 32. This allows the battery module 4 to be charged via USB.

[0143] The speaker 9 can be located within the accommodating space 130. The speaker 9 is spaced apart from the USB male connector and the battery module 4. Exemplarily, the speaker 9 is located within the fifth recess 74 of the first bracket 7. The motherboard 5 is located between the first bracket 7 and the battery module 4. The top surface 71 of the first bracket 7 faces the motherboard 5.

[0144] In some embodiments, a gap S1 is provided between the USB male connector 531 and the wall of the charging channel 125. The gap S1 connects the accommodating space 130 and the exterior of the housing 12. Sound emitted by the speaker 9 can be propagated to the exterior of the housing 12 through the gap S1 and the charging channel 125.

[0145] For example, the bottom surface of the fifth groove 74 is provided with a second through hole 75, which connects the fifth groove 74 and the charging channel 125. Sound emitted by the speaker 9 can be propagated to the outside of the housing 12 through the second through hole 75, the gap S1, and the charging channel 125. In other embodiments, the first bracket 7 may not have the fifth groove 74. The speaker 9 can be fixedly connected to the side of the first bracket 7 facing the charging channel 125.

[0146] In some embodiments, the charging case 10 may further include a sealing foam 161. The sealing foam 161 is connected between the bottom surface 72 of the first support 7 and the outer shell 12. The sealing foam 161, the bottom surface 72 of the first support 7, and the outer shell 12 enclose a second space 15. A first through hole 73 connects to the second space 15. A second through hole 75 connects to the second space 15. The charging channel 125 also connects to the second space 15. The sealing foam 161 can help fix the relative position of the first support 7 and the outer shell 12, and can also be used to concentrate the sound of the speaker 9, so that the sound of the speaker 9 is emitted through the charging channel 125 as much as possible. The sound emitted by the speaker 9 can be propagated to the outside of the outer shell 12 through the second through hole 75, the second space 15, the gap S1, and the charging channel 125. The sound propagation path emitted by the speaker 9 is shown by the dashed arrow in the figure.

[0147] In some embodiments, the charging case 10 may also include a waterproof and breathable membrane (not shown). The waterproof and breathable membrane may be connected to the USB male connector 531 and the housing 12, covering the gap S1 between the USB male connector 531 and the charging channel 125. The waterproof and breathable membrane can be used to prevent external moisture and dust from entering the second space 15 through the charging channel 125 and interfering with the operation of the internal components of the housing 12.

[0148] The charging coil module 6 can be located within the accommodating space 130. Exemplarily, the charging coil module 6 may include a wireless charging coil 61 and a magnetic shielding plate 62. The wireless charging coil 61 is connected to the magnetic shielding plate 62. The charging coil is electrically connected to the motherboard 5. The battery module 4 is electrically connected to the motherboard 5. The wireless charging coil 61 can be used to wirelessly charge the battery module 4. The magnetic shielding plate 62 can be used to isolate electromagnetic signals, preventing other devices from interfering with the wireless charging effect.

[0149] In some embodiments, the wireless charging coil 61 may be disposed between the magnetic shielding plate 62 and the second sidewall 1212. Exemplarily, the magnetic shielding plate 62 may be located on the side of the battery module 4 closer to the second sidewall 1212.

[0150] In other embodiments, the charging coil module 6 may also exclude the magnetic shielding plate.

[0151] In some embodiments, the earphone holder 11 is inclined relative to the side wall of the outer casing 12. When the first and second earphones are located inside the earphone case 100, they can be placed at an angle relative to the XY plane, which can reduce the height of the charging case 10.

[0152] For example, the top surface 111 forms an acute angle with the second sidewall 1212. For instance, the included angle between the top surface 111 and the second sidewall 1212 can be 5°, 10°, 15°, 20°, etc.

[0153] In some embodiments, the charging case 10 may further include a dustproof mesh 170. The dustproof mesh 170 may be fixedly connected to the first bracket 7 and cover the second through hole 75. The dustproof mesh 170 can prevent dust from entering the fifth groove 74 through the charging channel 125 and the second through hole 75 without affecting the connection between the fifth groove 74 and the charging channel 125, thus preventing it from interfering with the operation of the speaker 9.

[0154] In some embodiments, the charging case 10 may further include an indicator light module 162. The indicator light module 162 may be fixedly connected to the earphone holder 11. The indicator light module 162 may be partially located within the first through-hole 123, protruding from the outer casing 12. The indicator light module 162 may be connected to and electrically connected to the first flexible circuit board 18. The first flexible circuit board 18 may be used to transmit electrical signals to the indicator light module 162.

[0155] In some implementations, the indicator light module 162 can be used to emit different colors of light to indicate the battery level of the headphone case. For example, it can display green when the headphone case has a full battery, red when the battery is low, and yellow when the battery is moderate.

[0156] Figure 19 yes Figure 5 The diagram shows a partial assembly of the charging box 10.

[0157] like Figure 18 and Figure 19 As shown, antenna 8 can be located in accommodating space 130. Antenna 8 is electrically connected to motherboard 5. Antenna 8 can establish a communication connection with an external receiver. Exemplarily, the external receiver can be a user's electronic device (e.g., a mobile phone). Charging box 10 may also include a controller (not shown) that can be used to control antenna 8 to emit signals, and the receiver can determine the distance between antenna 8 and mobile phone based on the signals emitted by antenna 8.

[0158] In some implementations, when the distance between the antenna 8 and the user's mobile phone exceeds a preset distance, the controller can be used to enable the speaker 9 to emit a sound to alert the user, reducing the risk of the earphone box 100 being lost. In some implementations, the controller can be located on the motherboard 5.

[0159] For example, the antenna 8 can be fixedly connected to the bottom surface 72 of the first bracket 7. The charging box 10 may also include an electrical connector 163. The antenna 8 is connected to and electrically connected to the electrical connector 163. The electrical connector 163 is connected to and electrically connected to the circuit board 51. The antenna 8 can achieve electrical connection with the motherboard 5 through the electrical connector 163.

[0160] In some embodiments, the electrical connector 163 may be a flexible circuit board. In other embodiments, the electrical connector 163 may also be a metal trace or cable.

[0161] The battery case 41 can be fixedly connected to the bottom surface 112 of the headphone stand 11. For example, the battery case 41 can be fixedly connected to the bottom surface 112 of the headphone stand 11 by screws.

[0162] Figure 20 yes Figure 3 The diagram shows a structural schematic of one embodiment of the protective cover 20. Figure 21 yes Figure 20 An exploded view of one embodiment of the protective cover 20 shown.

[0163] like Figure 20 and Figure 21 As shown, the protective cover 20 may include a housing 210, a second attracting magnet 220, and a Hall magnet 230. The protective cover 20 may be provided with a third receiving groove 231 and a fourth receiving groove 241. The third receiving groove 231 and the fourth receiving groove 241 may be spaced apart along a first direction.

[0164] For example, the housing 210 of the protective cover 20 may include an outer cover 2110 and an inner cover 2120. The inner cover 2120 is connected to the inside of the outer cover 2110, and the inner cover 2120 and the outer cover 2110 enclose a third space 261. The second attracting magnet 220 and the Hall magnet 230 may be disposed within the third space 261. A third receiving groove 231 and a fourth receiving groove 241 may be located on the inner cover 2120, with the opening of the third receiving groove 231 facing away from the outer cover 2110, and the opening of the fourth receiving groove 241 facing away from the outer cover 2110.

[0165] Figure 22 yes Figure 21 The diagram shows a structural schematic of one embodiment of the outer cover 2110 shown.

[0166] like Figure 22 As shown, the outer cover 2110 may include an outer cover body 2111 and a partition 2112. The outer cover body 2111 includes an outer surface 2113 and an inner surface 2114. The partition 2112 is connected to the inner surface 2114 of the outer cover body 2111. The partition 2112 and the inner surface 2114 of the outer cover body 2111 form a sixth groove 2115.

[0167] Figure 23 yes Figure 2a The image shows a cross-sectional view of one embodiment of the headphone case 100 at section line DD.

[0168] like Figure 23 As shown, when the earphone case 100 is closed, the protective cover 20 connects to the charging case 10. The protective cover 20 and the charging case 10 enclose a storage space 40. For example, along the Z-axis, the third receiving slot 231 can be positioned opposite to the first charging slot 13 and the first receiving slot 23. The fourth receiving slot 241 can be positioned opposite to the second charging slot 14 and the second receiving slot 24. The third receiving slot 231, the first charging slot 13, and the first receiving slot 23 constitute a first storage space 401, which can be used to store the first earphone. The fourth receiving slot 241, the second charging slot 14, and the second receiving slot 24 can constitute a second storage space 402, which can be used to store the second earphone.

[0169] The first storage space 401 and the second storage space 402 can constitute the storage space 40.

[0170] In other embodiments, the third receiving slot 231 and the fourth receiving slot 241 may also be connected. Alternatively, the protective cover 20 may only have a recessed structure for cooperating with the first charging slot 13, the first receiving slot 23, the second charging slot 14, and the second receiving slot 24 to house the first and second earphones.

[0171] Figure 24yes Figure 2a The image shows a cross-sectional view of one embodiment of the headphone case 100 at section line EE.

[0172] like Figure 24 As shown, the Hall magnet 230 of the protective cover 20 can be fixed to the inner cover 2120. The charging case 10 may include a Hall sensor 164. The Hall sensor 164 may be located within the accommodating space 130. For example, the Hall sensor 164 may be fixed to the bottom surface 112 of the earphone holder 11. When the earphone case 100 is in the closed state, the Hall magnet 230 and the Hall sensor 164 of the charging case 10 are positioned opposite each other along the Z-axis. The Hall sensor 164 is used to sense changes in the magnetic field of the Hall magnet 230 and obtain the magnetic field strength. The Hall sensor 164 can be electrically connected to the main board 5 (not shown) through the first flexible circuit board 18 (not shown). The main board 5 may be equipped with a controller, which can be used to determine whether the earphone case 100 is in the closed or open state based on the magnetic field strength of the Hall sensor 164.

[0173] Figure 25 yes Figure 2a The image shows a partial cross-sectional view of one embodiment of the headphone case 100 at section line FF.

[0174] like Figure 25 As shown, the second magnetic magnet 220 can be fixed to the inner cover 2120. When the headphone case 100 switches from an open state to a closed state, the second magnetic magnet 220 can be used to help the protective cover 20 reset. For example, along the Z-axis direction, the second magnetic magnet 220 can be positioned opposite to the first magnetic magnet 19. When the headphone case 100 switches from an open state to a closed state, the first and second magnetic magnets 19 can attract each other to help the headphone case 100 quickly switch states and the protective cover 20 accurately reset.

[0175] The above describes several embodiments of the charging case 10 and the protective cover 20 with reference to the accompanying drawings. The following describes an embodiment of the rotating component 30 and a rotating connection method between the charging case 10 and the protective cover 20 with reference to the accompanying drawings.

[0176] Figure 26 yes Figure 3 An exploded view of one embodiment of the rotating assembly 30 shown.

[0177] like Figure 26 As shown, the rotating assembly 30 may include a rotor 310, a first rotating shaft 320, a second rotating shaft 330, and a torsion spring 340. Both the second rotating shaft 330 and the first rotating shaft 320 are rotatably connected to the rotor 310. One end of the torsion spring 340 is connected to the first rotating shaft 320, and the other end is connected to the second rotating shaft 330.

[0178] Figure 27 yes Figure 26 The diagram shows an assembly schematic of one embodiment of the first rotating shaft 320 and the charging box 10 shown.

[0179] like Figure 27 As shown. The first rotating shaft 320 can be fixed to the housing 12. For example, the middle part of the first rotating shaft 320 can be fixed in the first rotating hole 1221 of the protrusion 122 of the housing 12, and both ends protrude from the first rotating hole 1221.

[0180] Figure 28 yes Figure 26 The diagram shows a structural schematic of one embodiment of the rotor 310 shown. Figure 29 yes Figure 28 The diagram shows the structure of rotor 310 at another angle.

[0181] like Figure 28 and Figure 29 As shown, the rotor 310 includes a rotor body 311, a first extension 312, and a second extension 313. The first extension 312 and the second extension 313 are spaced apart. The first extension 312 and the second extension 313 are respectively connected to both ends of the rotor body 311. The first extension 312 is provided with a first connecting hole 3121, and the second extension 313 is provided with a second connecting hole 3131. For example, the rotor body 311 includes a first side surface 3111 and a second side surface 3112 disposed opposite to each other. The first extension 312 and the second extension 313 are connected to the first side surface 3111 of the rotor body 311. The first extension 312 and the second extension 313 can be arranged spaced apart along a first direction.

[0182] The rotor body 311 protrudes towards the second side surface 3112, forming a protrusion 3113. The rotor body 311 has a seventh groove 3114 located within the protrusion 3113. The protrusion 3113 is spaced apart from the first extension 312 and the second extension 313. The opening of the seventh groove 3114 is located on the first side surface 3111 of the rotor body 311. The opening of the seventh groove 3114 is located between the first extension 312 and the second extension 313.

[0183] The rotor body 311 may be provided with a third connecting hole 3115 and a fourth connecting hole 3116. Both the third connecting hole 3115 and the fourth connecting hole 3116 are connected to the seventh groove 3114. The third connecting hole 3115 and the fourth connecting hole 3116 are spaced apart. For example, the third connecting hole 3115 and the fourth connecting hole 3116 may be spaced apart along a first direction and located on both sides of the seventh groove 3114.

[0184] Figure 30 yes Figure 26 The diagram shows an assembly schematic of one embodiment of the second rotating shaft 330 and the housing 12 shown.

[0185] like Figure 30 As shown, the second rotating shaft 330 is fixedly connected to the rotor body 311. For example, one end of the second rotating shaft 330 is located within the third connecting hole 3115, and the other end is located within the fourth connecting hole 3116. The middle portion of the second rotating shaft 330 protrudes into the seventh groove 3114.

[0186] Figure 31 yes Figure 2a The image shows a partial cross-sectional view of one embodiment of the headphone case 100 at section line FF. Figure 32 This is a partial structural diagram of one embodiment of the rotating assembly 30 connecting to the outer shell 12 of the charging box 10.

[0187] like Figure 31 and Figure 32 As shown, when the rotating assembly 30 is rotatably connected to the charging box 10 and the protective cover 20, the rotor body 311 can be fixedly connected to the protective cover 20. For example, the rotor body 311 can be fixedly connected to the inner surface 2114 of the outer cover body 2111 and located in the sixth groove 2115.

[0188] The middle part of the first rotating shaft 320 is fixed to the protrusion 122. Figure 31 The first rotating hole 1221 of the protrusion 122 and the body 121 is schematically distinguished by dashed lines. The first end of the first rotating shaft 320 is rotatably connected to the first extension 312, and the second end of the first rotating shaft 320 is rotatably connected to the second extension 313. The middle part of the first rotating shaft 320 is connected between the first end and the second end of the first rotating shaft 320. For example, one end of the first rotating shaft 320 is rotatably connected to the first connecting hole 3121, and the other end can be rotatably connected to the second connecting hole 3131. In this way, the middle part of the first rotating shaft 320 is fixed to the outer shell 12, and the first end and the second end of the first rotating shaft 320 are rotatably connected to the protective cover 20. The charging case 10 and the protective cover 20 are rotatably connected.

[0189] In some embodiments, the protrusion 122 and the body portion 121 can be an integrated structural component. It is understood that, compared to connecting the protrusion 122 to the body portion 121 by means of adhesive or welding, this method prevents the protrusion 122 from detaching from the body portion 121, resulting in a stronger connection between the rotating assembly 30 and the housing 12. Furthermore, it eliminates an assembly step, reducing costs.

[0190] In some embodiments, the protrusion 122 may be connected to the top surface 1219 of the body portion 121. The top surface 1219 of the body portion 121 faces the protective cover 20. It is understood that, compared to placing the protrusion 122, which has the first rotating hole 1221, on the side of the top surface 1219 of the body portion 121 away from the protective cover 20, placing the protrusion 122 on the side of the top surface 1219 of the body portion 121 closer to the protective cover 20 can save internal space of the charging case 10 and prevent the protrusion 122 from occupying the accommodating space 130 of the charging case 10.

[0191] The torsion spring 340 may include a first connecting portion 341, a second connecting portion 342, and a deformable portion 343. The deformable portion 343 is fixedly connected between the first connecting portion 341 and the second connecting portion 342. The deformable portion 343 has the ability to deform; when the deformable portion 343 is subjected to an external force, it will deform, and when the external force is removed, the deformable portion 343 will return to its initial shape. The first connecting portion 341 is rotatably connected to the first rotating shaft 320. The second connecting portion 342 is rotatably connected to the second rotating shaft 330. For example, the first connecting portion 341 is located within the second rotating hole 1222 of the protrusion 122. The second connecting portion 342 may be located within the seventh groove 3114 and rotatably connected to the second rotating shaft 330.

[0192] When the earphone case 100 switches from the closed state to the open state, the protective cover 20 is rotatably connected to the charging case 10 via the first pivot 320, and the torsion spring 340 is deformed by force; when the earphone case 100 switches from the open state to the closed state, the protective cover 20 returns to its original shape by the force of the torsion spring 340 after deformation, thus achieving reset.

[0193] Figure 33 yes Figure 26 The diagram shows a structural schematic of one embodiment of the limiting member 350 shown.

[0194] like Figure 33 As shown, the rotating assembly 30 may further include a limiting member 350. The limiting member 350 may include a first limiting portion 351 and a second limiting portion 352. The first limiting portion 351 may be provided with a first limiting hole 3511. The second limiting portion 352 may be provided with a second limiting hole 3521.

[0195] Figure 34 This is a partial structural diagram of one embodiment of the rotating assembly 30 connecting to the outer shell 12 of the charging box 10. Figure 35 yes Figure 34 The structure shown is a partial cross-sectional view of one embodiment at section line GG.

[0196] like Figure 35 and Figure 35As shown, when the limiting member 350 is connected to the first rotating shaft 320, one end of the first rotating shaft 320 can be located in the first limiting hole 3511, and the other end can be located in the second limiting hole 3521. The limiting member 350 can be used to limit the length of the two ends of the first rotating shaft 320 extending out of the first rotating hole 1221 respectively.

[0197] For example, the first limiting portion 351 may be located between the protrusion 122 of the housing 12 and the first extension 312 of the rotor 310. The second limiting portion 352 may be located between the protrusion 122 of the housing 12 and the second extension 313 of the rotor 310. The first limiting portion 351 and the second limiting portion 352 can be used to reduce the risk of displacement of the first rotating shaft 320 along the length direction.

[0198] In some embodiments, the rotating assembly 30 may further include a first elastic ring 36 and a second elastic ring 37. The first elastic ring 36 is sleeved on the first rotating shaft 320 and located between the first rotating shaft 320 and the wall of the first limiting hole 3511. The second elastic ring 37 may be sleeved on the first rotating shaft 320. The second elastic ring may be located between the wall of the first rotating shaft 320 and the second limiting hole 3521. The first elastic ring 36 and the second elastic ring 37 have deformability. When a force is applied to the first elastic ring 36 and the second elastic ring 37, they can deform. The first elastic ring 36 abuts against the wall of the first rotating shaft 320 and the first limiting hole 3511. The second elastic ring 37 abuts against the wall of the first rotating shaft 320 and the second limiting hole 3521. In this way, by setting the first elastic ring 36 and the second elastic ring 37, the connection strength between the first rotating shaft 320 and the limiting member 350 can be better, further reducing the risk of displacement of the first rotating shaft 320 along the length direction.

[0199] In some embodiments, the first elastic ring 36 may be made of silicone. The second elastic ring 37 may also be made of silicone.

[0200] This application describes an earphone case 100 in detail with reference to the accompanying drawings. The earphone case 100 includes a case body 1, a first charging pin group 2, and a second charging pin group 3. The first charging pin group 2 and the second charging pin group 3 are disposed at intervals on the case body 1, and are arranged at intervals along a first direction. The first charging pin group 2 is used to charge a first earphone, and the second charging pin group 3 is used to charge a second earphone. The first charging pin group 2 includes a first positive charging pin 21 and a first negative charging pin 22. The second charging pin group 3 includes a second positive charging pin 31 and a second negative charging pin 32. The connection between the first positive charging pin 21 and the second positive charging pin 31 is a first connection line. The connection between the first negative charging pin 22 and the second negative charging pin 32 is a second connection line. The first connection line and the second connection line are intersecting.

[0201] Understandably, the arrangement directions of the first positive charging pin 21 and the first negative charging pin 22 in the first charging slot 13, and the arrangement directions of the second positive charging pin 31 and the second negative charging pin 32 in the second charging slot 14, are reversed. This way, when the earphone case 100 is used to charge the first and second earphones, the first earphone can be charged in either the first charging slot 13 or the second charging slot 14. In other words, when charging the first and second earphones, there is no need to distinguish between left and right ears; the first positive charging pin 21 and the first negative charging pin 22 can charge either the first or the second earphone. Similarly, the second positive charging pin 31 and the second negative charging pin 32 can charge either the first or the second earphone. This provides a better user experience.
