Description

Technical Field

[0001] This application relates to the field of earphones, and particularly to an earphone case and an earphone case assembly. Background Art

[0002] With the continuous development of electronic technology and the increasing demand for portability by users, wireless earphones are favored by more and more users. Generally, wireless earphones are used in conjunction with an earphone case, which can store the wireless earphones and charge the wireless earphones. The earphone case is provided with a first charging pin group and a second charging pin group at the same time. The first charging pin group is matched to charge the left earphone, and the second charging pin group is matched to charge the right earphone. When one of the first charging pin group and the second charging pin group fails, one of the left earphone or the right earphone cannot be charged. Summary of the Invention

[0003] This application provides an earphone case and an earphone case assembly.

[0004] In a first aspect, 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 charging pin group and the second charging pin group are arranged on the case body at intervals in 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, and the first positive charging pin and the first negative charging pin are arranged at intervals in a second direction, where the second direction is different from the first direction. The second charging pin group includes a second positive charging pin and a second negative charging pin, and the second positive charging pin and the second negative charging pin are arranged at intervals in a third direction, where the third direction is different from the first direction. The connection line between the first positive charging pin and the second positive charging pin is a first connection line, and the connection line between the first negative charging pin and the second negative charging pin is a second connection line, and the first connection line and the second connection line are arranged in a cross manner.

[0005] It can be understood that the arrangement directions of the first positive charging pin and the first negative charging pin in the first charging slot and the arrangement directions of the second positive charging pin and the second negative charging pin in the second charging slot are set to be opposite. In this way, when the earphone case is used to charge the first earphone and the second earphone, the first earphone can be charged in the first charging slot or in the second charging slot. In other words, when charging the first earphone and the second earphone, there is no need to distinguish between the left and right ears. For example, the first positive charging pin and the first negative charging pin 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 charging pin and the second negative charging pin relative to the first earphone can be the same as the directions of the first positive charging pin and the first negative charging pin relative to the first earphone. Therefore, the second charging pin group can also charge the first earphone. The charging of the second earphone is the same. In this way, when the earphone case charges the first earphone and the second earphone, when one of the first charging pin group and the second charging pin group fails, the first earphone and the second earphone can be charged through the other intact charging pin group.

[0006] In a possible implementation manner, 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.

[0007] It can be understood that when the first earphone and the second earphone are charging, the first earphone can rotate a certain angle in a direction away from the second charging pin group. The second earphone body can rotate a certain angle in a direction away from the first charging pin group. In this way, when the distance between the first positive charging pin and the second negative charging pin remains unchanged, the distance of the earphone case in the first direction can be reduced.

[0008] In a possible implementation manner, 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.

[0009] In a possible implementation manner, the first positive charging pin and the second negative charging pin are symmetric about a symmetry plane, and the first negative charging pin and the second positive charging pin are symmetric about the symmetry plane. The symmetry plane is perpendicular to the first direction.

[0010] It can be understood that when the first earphone and the second earphone are charging in the earphone case, the first earphone and the second earphone can be symmetrically arranged about the symmetry plane, which is convenient for the user to pick up and place.

[0011] In a possible implementation, the case body includes a headphone holder and a housing. The headphone holder is connected to the inner side of the housing, and the headphone holder and the housing enclose a receiving space. The headphone case further includes a battery disposed in the receiving space. The headphone holder is provided with a first charging slot and a second charging slot, and the first charging slot, the second charging slot and the receiving space are spaced apart from each other. A first positive charging pin and a first negative charging pin are disposed on the headphone holder. One end of the first positive charging pin and one end of the first negative charging pin are exposed relative to the first charging slot, and the other end of the first positive charging pin and the other end of the first negative charging pin are located in the receiving space and are electrically connected to the battery. A second positive charging pin and a second negative charging pin are disposed on the headphone holder. One end of the second positive charging pin and one end of the second negative charging pin are exposed relative to the second charging slot, and the other end of the second positive charging pin and the other end of the second negative charging pin are located in the receiving space and are electrically connected to the battery.

[0012] In a possible implementation, the housing is provided with a charging channel, and the charging channel communicates with the receiving space. The headphone case includes a USB male head, and the USB male head and the battery are spaced apart. A part of the USB male head is disposed in the receiving space, and a part is disposed in the charging channel. The USB male head is electrically connected to the first positive charging pin, the first negative charging pin, the second positive charging pin and the second negative charging pin. In this way, the headphone case can be charged by using the USB wired charging method.

[0013] In a possible implementation, the headphone case includes a speaker disposed in the receiving space, and the speaker, the USB male head and the battery are spaced apart from each other. There is a gap between the USB male head and the wall surface of the charging channel, and the sound emitted by the speaker is transmitted to the outside of the case body through the gap and the charging channel.

[0014] It can be understood that the sound emission of the speaker and the charging of the headphone case can share the charging channel, which can avoid opening an additional hole in the housing for the sound emission of the speaker, reduce one process, and save the manufacturing cost of the headphone case.

[0015] In a possible implementation, the headphone case includes a wireless charging coil located in the receiving space, and the wireless charging coil and the battery are spaced apart from each other. The wireless charging coil is electrically connected to the first positive charging pin, the first negative charging pin, the second positive charging pin and the second negative charging pin. In this way, the headphone case can be charged by using the wireless charging method.

[0016] In a possible implementation, the headphone case further includes a protective cover and a first rotating shaft, and the protective cover is rotatably connected to one end of the housing. The middle part of the first rotating shaft is fixed to the housing, the first end part of the first rotating shaft and the second end part of the first rotating shaft rotatably connect the protective cover, and the middle part of the first rotating shaft is connected between the first end part and the second end part of the first rotating shaft.

[0017] It can be understood that using the housing to fix the first rotating shaft can eliminate the need for an additional fixing structure to fix the first rotating shaft, and the connection strength between the first rotating shaft and the housing is better, and the assembly process is simpler.

[0018] In a possible implementation manner, the housing includes a body portion and a convex portion. The convex portion protrudes from the surface of the body portion facing the protective cover, and the earphone bracket is connected to the inner side of the body portion. The middle part of the first rotating shaft is fixed to the convex portion.

[0019] It can be understood that the convex portion protrudes from the surface of the body portion facing the protective cover, and the middle part of the first rotating shaft is fixed to the convex portion. That is, the first rotating shaft is fixedly connected to one side of the body portion close to the protective cover. Compared with the technical solution of fixing the first rotating shaft to the side of the body portion away from the protective cover, this solution can save the internal space of the housing and prevent the first rotating shaft and the corresponding fixing structure from occupying the internal space of the housing.

[0020] In a possible implementation manner, the earphone bracket is inclined relative to the side wall of the housing.

[0021] It can be understood that when the first earphone and the second earphone are located in the earphone box, the first earphone and the second earphone are arranged on the earphone bracket. When the earphone bracket is placed inclined relative to the side wall of the housing, the first earphone and the second earphone can also be placed inclined relative to the side wall of the housing. In the height direction of the earphone box, the height of the earphone in the earphone box can be reduced, which is beneficial to reducing the height of the earphone box.

[0022] In a second aspect, the present application provides an earphone box assembly. The earphone box assembly includes an earphone and an earphone box, and the earphone is arranged in the earphone box. It can be understood that the earphone box can be used to protect the earphone.

[0060] The embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0061] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. 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. Among them, "fixed connection" means that the components are connected to each other and the relative positional relationship after connection remains unchanged. It should be understood that when component A is fixedly connected to component C through component B, a change in the relative positional relationship due to the deformation of component A, component B, and component C itself is allowed. Among them, the integration of two components through an integral molding process means that during the process of forming one of the two components, the component is connected to the other component together without the need to connect the two components through a reprocessing method (such as bonding, welding, snap connection, screw connection).

[0062] The orientation terms mentioned in the embodiments of the present application, such as "upper", "lower", "side", etc., are only with reference to the direction of the accompanying drawings. Therefore, the orientation terms used are for better and clearer description and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the embodiments of the present application.

[0063] The term "a plurality of" means at least two. The term "above" includes the number itself. The term "and / or" is an associative relationship describing associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The terms "first", "second", etc. are used only for descriptive purposes and should not be construed as implying or suggesting relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first", "second" may explicitly or implicitly include one or more of such features.

[0064] Figure 1 It is a schematic structural diagram of an implementation manner of the earphone case assembly 1000 provided by an embodiment of the present application. Figure 2a is Figure 1 A schematic structural diagram of an implementation manner of the earphone case 100 shown in [Figure] in the closed state. Figure 2b is Figure 1 A schematic structural diagram of an implementation manner of the earphone case 100 shown in [Figure] in the open state.

[0065] As Figure 1 , Figure 2a and Figure 2b 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 the wireless earphones. The earphones can be in-ear earphones, semi-open earphones or open earphones 200. In the present application, clip-on wireless earphones are taken as an example for introduction.

[0066] Exemplarily, the earphone case 100 can store two earphones 200 at the same time and charge the two earphones 200. For convenience of description, these two earphones 200 are respectively referred to as the first earphone and the second earphone (the first earphone is Figure 1 the left earphone in [Figure], and the second earphone is Figure 1 the right earphone in [Figure]).

[0067] In some implementation manners, the first earphone and the second earphone can be the same, that is, the outer shapes and the internal device arrangements of the first earphone and the second earphone can be the same.

[0068] The earphone case 100 can have a storage space 40, and the storage space 40 can be used to accommodate the earphones 200. The earphone case 100 can include a closed state (as Figure 2a shown) and an open state (as Figure 2b shown). When the earphone case 100 is in the open state, the storage space 40 is exposed. When the earphones 200 are in the earphone case 100, the earphones 200 in the earphone case 100 can be presented, and the user can take out the earphones 200, or the user can place the earphones 200 in the storage space 40.

[0069] The earphone case 100 can be a vertically opening and closing earphone case, a push-pull opening and closing earphone case, etc. In this application, the vertically opening and closing earphone case 100 is taken as an example for introduction.

[0070] For convenience of description, the width direction of the earphone case 100 is defined as the X-axis, the thickness direction of the earphone case 100 is defined as the Y-axis, and the height direction of the earphone case 100 is defined as the Z-axis.

[0071] In some embodiments, 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, and the relationship among the three satisfies W > H > D.

[0072] Figure 3 Yes Figure 2a It is an exploded schematic diagram of an embodiment of the earphone case 100 shown in

[0073] As Figure 3 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 achieve relative rotation through the rotating assembly 30, and thus the earphone case 100 can be switched between a closed state and an open state.

[0074] Figure 4 Yes Figure 3 It is a structural schematic diagram of an embodiment of the charging case 10 shown in Figure 5 Yes Figure 4 It is an exploded schematic diagram of an embodiment of the charging case 10 shown in

The battery module 4, the main board 5, the charging coil module 6, the first bracket 7, the antenna 8, the speaker 9, the magnet 19, and the first flexible circuit board 18 may be disposed inside the case body 1. The first charging pin group 2 can be used to charge the first earphone. The second charging pin group 3 can be used to charge the second earphone. Exemplarily, the case body 1 may include an earphone bracket 11 and a housing 12. The earphone bracket 11 is connected to the inner side of the housing 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.

The second receiving groove 24 may cooperate with the second charging slot 14 to receive the second earphone.

[0085] Exemplarily, the first receiving groove 23, the second receiving groove 24, the first charging slot 13, and the second charging slot 14 are arranged at intervals. The first receiving groove 23 may be provided on a side of the first charging slot 13 away from the second charging slot 14. The second receiving groove 24 may be provided on a 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 groove 23 and the second receiving groove 24.

[0086] In other embodiments, the first receiving groove 23 may be provided on a side of the first charging slot 13 close to the second charging slot 14. The second receiving groove 24 may be provided on a side of the second charging slot 14 close to the first charging slot 13.

[0087] In some embodiments, the first receiving groove 23 and the second receiving groove 24 may be symmetric about the symmetry plane S.

[0088] The earphone holder 11 may further have a first groove 1121, a second groove 1122, a third groove 1123, and a fourth groove 1124 that are arranged at intervals. 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 earphone holder 11.

[0089] In some embodiments, the earphone holder 11 may further include a first positioning post 113. The first positioning post 113 may be adjacent to and spaced from the first charging hole 115. The first positioning post 113 is located on one side of the bottom surface 112 of the earphone holder 11.

[0100] The connection line between the first positive charging pin 21 and the second positive charging pin 31 is the first connection line. The connection line between 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 arranged in a cross manner. It should be noted that the cross arrangement here means that the projection of the first connection line on the X-Y plane and the projection of the second connection line on the X-Y plane cross. In space, the first connection line and the second connection line may intersect or may not intersect.

[0101] It can be understood that the arrangement directions of the first positive charging pin 21 and the first negative charging pin 22 in the first charging groove 13 and the arrangement directions of the second positive charging pin 31 and the second negative charging pin 32 in the second charging groove 14 are set to be opposite. In this way, when the earphone case 100 is used to charge the first earphone and the second earphone, the first earphone can be charged in the first charging groove 13 or can be rotated by an angle and charged in the second charging groove 14 (for example, the first earphone can be charged in the first charging groove or can be rotated 180° in the X-Y plane and charged in the second charging groove). The same applies to the second earphone. In other words, when charging the first earphone and the second earphone, it is not necessary to distinguish between the left and right ears. The first positive charging pin 21 and the first negative charging pin 22 can charge the first earphone or can charge the second earphone. The second positive charging pin 31 and the second negative charging pin 32 can charge the first earphone or can charge the second earphone. In this way, the user experience is better.

[0102] Exemplarily, the line connecting the centers of the first positive charging pin 21 and the second positive charging pin 31 is the first line. The line connecting the centers of the first negative charging pin 22 and the second negative charging pin 32 is the second line.

[0103] 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.

[0104] In some embodiments, the first positive charging pin 21 and the second negative charging pin 32 may be symmetric about the symmetry plane S. The first negative charging pin 22 and the second positive charging pin 31 may be symmetric about the symmetry plane S.

[0105] In some embodiments, the distance between the second positive charging pin 31 and the first negative charging pin 22 may 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 may be arranged in an "eight" shape. That is, the first line and the second line may be arranged in an "eight" shape.

[0106] In some embodiments, the projection of the first line on the X-Y plane is the first projection. The first projection may be arranged at an angle with the Y axis. Exemplarily, the angle may be 2°, 5°, or 8°.

[0107] In some embodiments, the projection of the first line on the Y-Z plane is the second projection. The second projection may be arranged at an angle with the Y axis. Exemplarily, the angle may be 5°, 10°, 15°, 20°, etc. When the first earphone is charging, it can be placed obliquely relative to the X-Y plane, which can reduce the height of the charging case 10.

[0109] As Figure 5 and Figure 10 shown, the 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 correspondingly arranged in the first groove 1121. The second magnet 192 is correspondingly arranged in the second groove 1122. The third magnet 193 is correspondingly arranged in the third groove 1123. The fourth magnet 194 is correspondingly arranged in the fourth groove 1124. Exemplarily, the first magnet 191, the second magnet 192, the third magnet 193, and the fourth magnet 194 may be arranged at intervals in the first direction.

[0110] The magnet 19 may further include a first attracting magnet 19. When the earphone case 100 is switched from the open state to the closed state, the first attracting magnet 19 can be used to help the protective cover 20 reset.

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. Exemplarily, when the first charging pin is disposed in the first charging hole 115, the second end 212 of the first positive charging pin 21 is exposed on 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 and electrically connected to the first electrical connection portion 182 of the first flexible circuit board 18.

When the flexible circuit is fixedly connected to the bottom surface 112 of the earphone bracket 11, the positioning post is located in the avoidance hole 181. In this way, the first positioning post 113 can be used to assist in positioning the first flexible circuit board 18 when installing the first flexible circuit board 18, and help the first positive charging pin 21 quickly locate to the connection position with the first flexible circuit board 18. At the same time, it can also reduce the risk that the displacement of the first flexible circuit board 18 causes the disconnection of the connection between the first positive charging pin 21 and the first flexible circuit board 18.

[0124] In some embodiments, the cover plate 412 of the battery case 41 may be made of stainless steel. When the batteries 42 catch fire, the cover plate 412 made of stainless steel can block the spread of the fire.

[0125] In other embodiments, the battery case 41 may not include the cover plate 412.

[0126] Figure 15 Yes Figure 4 It is a partial sectional view of an embodiment of the charging case 10 at the section line B - B shown in Figure 4 .

[0127] As Figure 15 shown, the earphone bracket 11 may be connected to the inner side of the housing 12, and the earphone bracket 11 and the housing 12 enclose an accommodation space 130.

The top surface 71 of the first bracket 7 faces the main board 5.

[0143] In some embodiments, there is a gap S1 between the USB male connector 531 and the wall surface of the charging channel 125. The gap S1 communicates the accommodation space 130 and the outside of the housing 12. The sound emitted by the speaker 9 can be transmitted to the outside of the housing 12 through the gap S1 and the charging channel 125.

[0144] Exemplarily, the bottom surface of the fifth groove 74 is provided with a second through hole 75, and the second through hole 75 communicates the fifth groove 74 and the charging channel 125. The sound emitted by the speaker 9 can be transmitted 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 be provided with the fifth groove 74 either.

The second through hole 75 communicates the second space 15. The charging channel 125 also communicates the second space 15. The sealing foam 161 can help fix the relative positions of the first bracket 7 and the housing 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 transmitted to the outside of the housing 12 through the second through hole 75, the second space 15, the gap S1, and the charging channel 125. The sound propagation path of the speaker 9 is shown by the dotted arrow in the figure.

[0146] In some embodiments, the charging case 10 may further include a waterproof breathable membrane (not shown in the figure). The waterproof breathable membrane can be connected to the USB male connector 531 and the housing 12 to cover the gap S1 between the USB male connector 531 and the charging channel 125. The waterproof breathable membrane can be used to prevent external water vapor and dust from entering the second space 15 through the charging channel 125 and interfering with the operation of the components inside the housing 12.

[0149] In other embodiments, the charging coil module 6 may not include a magnetic shielding plate.

[0150] In some embodiments, the earphone bracket 11 is inclined with respect to the side wall of the housing 12. When the first earphone and the second earphone are located within the earphone case 100, they can be placed inclined relative to the X-Y plane, which can reduce the height of the charging case 10.

[0151] Exemplarily, the top surface 111 forms an acute angle with the second side wall 1212. For example, the angle between the top surface 111 and the second side wall 1212 can be 5°, 10°, 15°, 20°, etc.

[0152] In some embodiments, the charging case 10 may further include a dust-proof net 170. The dust-proof net 170 can be fixedly connected to the first bracket 7 and cover the second through hole 75. The dust-proof net 170 can prevent dust from entering the fifth groove 74 through the charging channel 125 and the second through hole 75 while not affecting the communication between the fifth groove 74 and the charging channel 125, thus interfering with the operation of the speaker 9.

[0153] In some embodiments, the charging case 10 may further include an indicator light module 162. The indicator light module 162 can be fixedly connected to the earphone bracket 11. The indicator light module 162 can be partially located within the first through hole 123 and exposed outside the housing 12.

[0179] As Figure 28 and Figure 29 shown, the rotor 310 includes a rotor body 311, a first extension part 312 and a second extension part 313. The first extension part 312 and the second extension part 313 are arranged at intervals. The first extension part 312 and the second extension part 313 are respectively connected to both ends of the rotor body 311. The first extension part 312 is provided with a first connection hole 3121, and the second extension part 313 is provided with a second connection hole 3131. Exemplarily, the rotor body 311 includes a first side surface 3111 and a second side surface 3112 arranged opposite to each other. The first extension part 312 and the second extension part 313 are connected to the first side surface 3111 of the rotor body 311. The first extension part 312 and the second extension part 313 can be arranged at intervals in the first direction.

[0180] The rotor body 311 bulges towards the direction of the second side surface 3112 to form a convex part 3113. The rotor body 311 is provided with a seventh groove 3114, and the seventh groove 3114 is located in the convex part 3113. The convex part 3113 and the first extension part 312, the second extension part 313 are arranged at intervals. 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 part 312 and the second extension part 313.

[0181] The rotor body 311 can be provided with a third connection hole 3115 and a fourth connection hole 3116. Both the third connection hole 3115 and the fourth connection hole 3116 communicate with the seventh groove 3114. The third connection hole 3115 and the fourth connection hole 3116 are arranged at intervals. Exemplarily, the third connection hole 3115 and the fourth connection hole 3116 can be arranged at intervals in the first direction and are located on both sides of the seventh groove 3114.

[0182] Figure 30 is Figure 26Assembly schematic diagram of an embodiment of the second rotating shaft 330 and the housing 12 shown in the figure.

[0183] As Figure 30 shown, the second rotating shaft 330 is fixedly connected to the rotor body 311. Exemplarily, one end of the second rotating shaft 330 is located in the third connecting hole 3115, and the other end is located in the fourth connecting hole 3116. The middle part of the second rotating shaft 330 is exposed in the seventh groove 3114.

[0184] Figure 31 is Figure 2a Partial sectional view of an embodiment of the earphone case 100 shown in the figure at the section line F-F. Figure 32 It is a partial structural schematic diagram of an embodiment in which the rotating assembly 30 is connected to the housing 12 of the charging case 10.

[0185] As Figure 31 and Figure 32 shown, when the rotating assembly 30 is rotatably connected to the charging case 10 and the protection cover 20, the rotor body 311 can be fixedly connected to the protection cover 20. Exemplarily, the rotor body 311 can be fixedly connected to the inner surface 2114 of the outer cover body 2111 and is located in the sixth groove 2115.

[0186] The middle part of the first rotating shaft 320 is fixed to the first rotating hole 1221 of the convex part 122 ( Figure 31 the convex part 122 and the body part 121 are schematically distinguished by a dotted line in the figure). The first end of the first rotating shaft 320 is rotatably connected to the first extension part 312, and the second end of the first rotating shaft 320 is rotatably connected to the second extension part 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. Exemplarily, one end of the first rotating shaft 320 is rotatably connected in the first connecting hole 3121, and the other end can be rotatably connected in the second connecting hole 3131. In this way, the middle part of the first rotating shaft 320 is fixed to the housing 12, and the first end and the second end of the first rotating shaft 320 are rotatably connected to the protection cover 20. The charging case 10 and the protection cover 20 are rotatably connected.

[0187] In some embodiments, the convex part 122 and the body part 121 can be an integrated structural member. It can be understood that compared with the way that the convex part 122 is connected to the body part 121 by gluing or welding, etc., the convex part 122 can be prevented from falling off the body part 121, and the connection strength between the rotating assembly 30 and the housing 12 is better. In addition, one assembly process is saved, and the cost can be reduced.

[0188] In some embodiments, the convex portion 122 may be connected to the top surface 1219 of the main body portion 121. The top surface 1219 of the main body portion 121 faces the protective cover 20. It can be understood that, compared with disposing the convex portion 122 provided with the first rotation hole 1221 on the side of the top surface 1219 of the main body portion 121 away from the protective cover 20, disposing the convex portion 122 on the side of the top surface 1219 of the main body portion 121 close to the protective cover 20 can save the internal space of the charging case 10 and prevent the convex portion 122 from occupying the accommodation space 130 of the charging case 10.

[0189] The torsion spring 340 may include a first connecting portion 341, a second connecting portion 342, and a deformation portion 343. The deformation portion 343 is fixedly connected between the first connecting portion 341 and the second connecting portion 342. The deformation portion 343 has the ability to deform. When the deformation portion 343 is subjected to an external force, it will deform, and when the external force is removed, the deformation portion 343 returns to its original shape. The first connecting portion 341 is rotatably connected to the first rotating shaft 320. The second connecting portion 342 may be rotatably connected to the second rotating shaft 330. Exemplarily, the first connecting portion 341 is located in the second rotation hole 1222 of the convex portion 122. The first connecting portion 341 may be rotatably connected to the convex portion 122. The second connecting portion 342 may be located in the seventh groove 3114 and rotatably connected to the second rotating shaft 330.

[0190] When the earphone case 100 is switched from the closed state to the open state, the protective cover 20 is rotatably connected to the charging case 10 through the first rotating shaft 320, and the torsion spring 340 is deformed by the force; when the earphone case 100 is switched from the open state to the closed state, the protective cover 20 is reset by the force of the torsion spring 340 to recover its original shape after deformation.

[0191] Figure 33 Yes Figure 26 A schematic structural diagram of an embodiment of the limiting member 350 shown in

[0192] As 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.

[0193] Figure 34 A partial structural schematic diagram of an embodiment of the rotating assembly 30 connected to the housing 12 of the charging case 10. Figure 35 Yes Figure 34 A partial cross-sectional view of an embodiment of the structure shown in

[0194] As 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 within the first limiting hole 3511, and the other end can be located within the second limiting hole 3521. The limiting member 350 can be used to limit the lengths of the two ends of the first rotating shaft 320 extending out of the first rotating hole 1221 respectively.

[0195] Exemplarily, the first limiting portion 351 can be located between the convex portion 122 of the housing 12 and the first extending portion 312 of the rotor 310. The second limiting portion 352 can be located between the convex portion 122 of the housing 12 and the second extending portion 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 in the length direction.

[0196] In some embodiments, the rotating assembly 30 can further include a first elastic ring 36 and a second elastic ring 37. Among them, the first elastic ring 36 is sleeved on the first rotating shaft 320, and the first elastic ring 36 is located between the first rotating shaft 320 and the wall surface of the first limiting hole 3511. The second elastic ring 37 can be sleeved on the first rotating shaft 320. The second elastic ring can be located between the first rotating shaft 320 and the wall of the second limiting hole 3521. The first elastic ring 36 and the second elastic ring 37 have the ability to deform. When a force is applied to the first elastic ring 36 and the second elastic ring 37, the first elastic ring 36 and the second elastic ring 37 can deform. The first elastic ring 36 abuts against the first rotating shaft 320 and the wall surface of the first limiting hole 3511. The second elastic ring 37 can abut against the first rotating shaft 320 and the wall of the second limiting hole 3521. In this way, by providing 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 made better, and further reduce the risk of displacement of the first rotating shaft 320 in the length direction.

[0197] In some embodiments, the first elastic ring 36 can be made of silicone. The second elastic ring 37 can also be made of silicone.

[0198] In the present application, a headphone case 100 is specifically introduced with reference to relevant drawings. The headphone 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 arranged on the case body 1 at intervals. The first charging pin group 2 and the second charging pin group 3 are arranged at intervals in a first direction. The first charging pin group 2 is used to charge the first earphone, and the second charging pin group 3 is used to charge the 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 line between the first positive charging pin 21 and the second positive charging pin 31 is the first connection line. The connection line between 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 arranged in a cross manner.

[0199] It can be understood that 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 set to be opposite. In this way, when the earphone case 100 is used to charge the first earphone and the second earphone, the first earphone can be charged in the first charging slot 13 or in the second charging slot 14. In other words, when the first earphone and the second earphone are charged, there is no need to distinguish between the left and right ears. The first positive charging pin 21 and the first negative charging pin 22 can charge the first earphone or the second earphone. The second positive charging pin 31 and the second negative charging pin 32 can charge the first earphone or the second earphone. In this way, the user experience is better.
