Therefore, features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0047] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. In an example, it can be a fixed connection, or a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection, or can communicate with each other; it can be a direct connection, or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements.

[0048] In the related art, users usually use a charging box to charge or store earphones. For example, when the earphones are low on power or do not need to be used, the user can place them in the charging box. The charging box includes a base and a cover, and the cover can move relative to the base to open and close the charging box. Generally, the charging box also includes a metal column, which can provide a guide for the movement of the cover relative to the base. However, due to the size of the metal column, the cover is prone to loosening or shaking during the movement relative to the base. For example, there is a gap between the metal column and the base and / or the cover, which will affect the stability of the opening and closing of the charging box. To solve the above problems, please refer to Figure 1 , an embodiment of the present application provides a charging box 100 and an earphone system 1000.

[0049] See also Figure 1 The earphone system 300 provided in the embodiment of the present application includes an earphone 200 and a charging box 100. The charging box 100 is used to charge the earphone 200. Since the earphone system 300 in this embodiment includes the charging box 100, it can be understood that the earphone system 300 includes at least the same beneficial effects as the charging box 100. Therefore, for the beneficial effects of the earphone system 300, please refer to the beneficial effects of the charging box 100 described below.

[0050] In certain embodiments of the present application, the earphones 200 can be worn on the user's ears and can be used in conjunction with devices such as mobile phones, computers, smart wearable devices (such as smart watches, smart bracelets, smart glasses, smart helmets, etc.), head-mounted display devices, and virtual reality devices. Specifically, in certain embodiments, the earphones 200 include air conduction earphones and bone conduction earphones. Among them, air conduction earphones, that is, air conduction earphones, are earphones that transmit sound through air vibrations. Bone conduction earphones, that is, bone conduction earphones, are earphones that convert sound into different mechanical vibrations and transmit sound waves through the human skull, bony labyrinth, inner ear lymph, spiral organ, auditory center, etc.

[0051] It should be noted that the user's ear includes the external auditory canal, cavum concha, cymba concha, triangular fossa, helix, and antitragus. The cavum concha, cymba concha, and triangular fossa have a certain depth and volume in three-dimensional space. The external auditory canal is a curved tube that extends from the external auditory meatus deep in the cavum concha to the eardrum.

[0052] Furthermore, in certain embodiments, the earphone 200 includes a transducer assembly 210 (including a first transducer assembly 2101 and a second transducer assembly 2103). The transducer assembly 210 is a structure within the earphone 200 that enables the user to hear sound. In one example, when the earphone 200 is a bone conduction earphone, the transducer assembly 210 is configured to be located in front of the ear when the earphone 200 is worn, so that the transducer assembly 210 does not block the external auditory canal. In another example, when the earphone 200 is an air conduction earphone, the transducer assembly 210 is configured to at least partially extend into at least one of the cavum conchae, the cymba conchae, and the triangular fossa when the earphone 200 is worn. It should be noted that the embodiments described below are based on the example of the earphone 200 being a bone conduction earphone.

[0053] Furthermore, in some embodiments, the earphones 200 include a battery compartment 220, a control compartment 230, a first earhook assembly 240, a second earhook assembly 250, and a back-hook assembly 260 disposed between the first earhook assembly 240 and the second earhook assembly 250. The first earhook assembly 240 and the second earhook assembly 250 are respectively hung on the left ear and the right ear. The battery compartment 220 can be disposed between the first earhook assembly 240 and the back-hook assembly 260, and the control compartment 230 can be disposed between the second earhook assembly 250 and the back-hook assembly 260. The first transducer assembly 2101 and the second transducer assembly 2103 are both configured to convert electrical signals into mechanical vibrations so that the user can hear sound.

[0054] Please combine Figure 4 In some embodiments, the charging box 100 includes a rechargeable battery 110 and a charging circuit 120. When the earphone 200 is placed in the charging box 100, the charging circuit 120 can transmit the power of the rechargeable battery 110 to the earphone 200 to charge the earphone 200.

[0055] Furthermore, please combine Figure 2 and Figure 3 In some embodiments, the charging box 100 is provided with a first electrical connector 15, and the earphone 200 is provided with a second electrical connector 270. When the earphone 200 is placed in the charging box 100, the first electrical connector 15 and the second electrical connector 270 are electrically connected.

[0056] Specifically, in certain embodiments, when the first electrical connector 15 is electrically connected to the second electrical connector 270, functions such as power and data transmission can be achieved between the charging case 100 and the earphones 200. For example, when the first electrical connector 15 is electrically connected to the second electrical connector 270, the charging circuit 120 can transfer power from the rechargeable battery 110 to the battery compartment 220 of the earphones 200 via the first electrical connector 15 and the second electrical connector 270, thereby charging the earphones 200. It should be noted that in certain embodiments, the first electrical connector 15 can be at least one of a spring pin and a spring element capable of achieving electrical connection; and the second electrical connector 270 can be a device capable of electrically connecting to the first electrical connector 15.

[0057] Furthermore, in some embodiments, the first electrical connector 15 includes multiple components, and the second electrical connector 270 includes multiple components. When the earphone 200 is placed in the charging box 100, the multiple first electrical connectors 15 and the multiple second electrical connectors 270 are electrically connected one by one.

[0058] Specifically, in some embodiments, a portion of the plurality of first electrical connectors 15 is used for power transmission, and another portion is used for signal transmission; correspondingly, a portion of the plurality of second electrical connectors 270 is used for power transmission, and another portion is used for signal transmission. The plurality of first electrical connectors 15 are arranged side by side on the charging box 100. Compared to a case where the plurality of first electrical connectors 15 are not arranged side by side on the charging box 100, on the one hand, this can reduce the space occupied by the first electrical connectors 15, making the structure more compact and facilitating the miniaturization of the charging box 100; on the other hand, it can facilitate the alignment of the first electrical connectors 15 and the second electrical connectors 270, thereby improving the convenience of electrical connection.

[0059] See also Figures 3 to 5 The charging box 100 provided in the embodiment of the present application includes a base 10, a cover 20 and a lifting assembly 30. The base 10 includes a connector 13. The cover 20 is connected to the base 10 and can be lifted and lowered relative to the base 10. The cover 20 includes an extension 23. The extension 23 partially extends into the connector 13 and can abut against the inner wall 131 of the connector. The lifting assembly 30 includes a first guide 31 and a second guide 33. The first guide 31 is provided on the side wall 231 of the extension, and the second guide 33 is provided on the inner wall 131 of the connector. The first guide 31 and the second guide 33 cooperate to limit the movement of the cover 20 relative to the base 10 in the horizontal direction. The horizontal direction is perpendicular to the lifting direction (Z1 / Z2) of the cover 20.

[0060] The base 10 is a structure in the charging box 100 for supporting the earphones 200. The material of the base 10 includes, but is not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. Exemplarily, the base 10 is made of plastic, which makes the charging box 100 lighter and easier for users to carry. In certain embodiments of the present application, the base 10 also includes a seat body 11, and a connector 13 extends from the seat body 11 toward the cover body 20. The rechargeable battery and the charging circuit are both arranged in the seat body 11. This makes the weight of the base 10 larger, reducing the possibility of the charging box 100 tipping over when the earphones 200 are stored in the charging box 100. The connector 13 may be provided with a moving space 130, and the extension member 23 partially extends into the moving space 130 and can abut against the inner wall 131 of the connector. In this way, the extension member 23 can be raised and lowered relative to the connector 13 in the moving space 130.

[0061] The cover 20 is a structure within the charging case 100 that cooperates with the base 10 to retain the earphones 200. Materials for the cover 20 include, but are not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, the cover 20 is made of plastic, which makes the charging case 100 lighter and easier for users to carry. It is understood that the material of the cover 20 can be the same as or different from that of the base 10.

[0062] Please combine Figure 5 In certain embodiments of the present application, the cover 20 further includes a main body 21, and an extension piece 23 extends from the main body 21 toward the base 10. In some embodiments, the main body 21 and the extension piece 23 are an integral structure, that is, the main body 21 and the extension piece 23 can be formed into a whole by an integral molding method, which can improve the stability of the connection between the main body 21 and the extension piece 23. In other embodiments, the main body 21 and the extension piece 23 are split structures, that is, the main body 21 and the extension piece 23 are two different structures. The main body 21 and the extension piece 23 can be combined together by a detachable connection method or a non-detachable connection method. Among them, the detachable connection method includes but is not limited to a snap connection or a bolt connection; the non-detachable connection method includes but is not limited to bonding or welding. It can be understood that the connection method between the base 11 and the connecting piece 13 is basically the same as the connection method between the main body 21 and the extension piece 23, and will not be repeated here.

[0063] The lifting assembly 30 is a structure within the charging case 100 that allows the cover 20 to be raised and lowered relative to the base 10, as well as restricts horizontal movement of the cover 20 relative to the base 10. In certain embodiments of the present application, the cover 20 is raised and lowered relative to the base 10 to switch between a pressing position and a releasing position. When the cover 20 is in the pressing position, it presses the earphones 200; when in the releasing position, it releases the earphones 200.

[0064] The pressing position may be: along the lifting direction of the cover 20 (the same as the height direction (Z1 / Z2) of the charging box 100), the lifting assembly 30 enables the cover 20 to move downward relative to the base 10 (the cover 20 moves relative to the base 10 along the direction from the cover 20 to the base 10) to the extreme position; the releasing position may be: along the lifting direction of the cover 20, the lifting assembly 30 enables the cover 20 to move upward relative to the base 10 (the cover 20 moves relative to the base 10 along the direction from the base 10 to the cover 20) to the extreme position. It is understandable that when the charging box 100 is in a normal state (for example, when the charging box 100 does not contain the earphones 200), the cover 20 can be in the pressing position, which can reduce the space occupied by the charging box 100 and make it easier for users to carry.

[0065] Specifically, in certain embodiments, when the cover 20 is in the compressed position, it can press the earphones 200, thereby limiting the position of the earphones 200 and preventing them from moving or shaking in the charging case 100, thereby improving the stability of the earphones 200 stored in the charging case 100. Furthermore, the compressed position of the cover 20 can prevent the earphones 200 from moving or shaking in the charging case 100, which could result in poor contact between the charging end (i.e., the second electrical connector 270) of the earphones 200 and the charging end (i.e., the first electrical connector 15) of the charging case 100. This improves the stability of the charging of the earphones 200 by the charging case 100 and ensures the normal function of charging and / or signal transmission. When the cover 20 is in the released position, the earphones 200 can be placed in the charging case 100; or the earphones 200 can be removed from the charging case 100.

[0066] In some embodiments, one of the first guide 31 and the second guide 33 is a protrusion and the other is a groove. In one example, the first guide 31 is a protrusion and the second guide 33 is a groove. In another example, the first guide 31 is a groove and the second guide 33 is a protrusion.

[0067] In which, when the first guide member 31 is a groove and the second guide member 33 is a protrusion, the first guide member 31 can be recessed from the side wall 231 of the extension member toward the center of the extension member 23; the second guide member 33 can protrude and extend from the inner wall 131 of the connecting member toward the center of the connecting member 13. When the extension member 23 extends into the connecting member 13, the second guide member 33 can extend into the first guide member 31 to guide the extension member 23 to rise and fall relative to the connecting member 13.

[0068] In other embodiments, one of the first guide member 31 and the second guide member 33 is a slider and the other is a slide rail. In one example, the first guide member 31 is a slider and the second guide member 33 is a slide rail. In another example, the first guide member 31 is a slide rail and the second guide member 33 is a slider.

[0069] In some embodiments, the first guide member 31 and the extension member 23 are integrally formed. That is, the first guide member 31 and the extension member 23 can be integrally formed to form a single unit, thereby improving the stability of the connection between the first guide member 31 and the extension member 23. Furthermore, compared to the related art where the charging box 100 includes a metal post, the integral structure of the first guide member 31 and the extension member 23 can reduce the number of assembly steps for the charging box 100, thereby improving the assembly efficiency of the charging box 100.

[0070] It is understood that in other embodiments, the first guide member 31 and the extension member 23 may be separate structures, that is, the first guide member 31 and the extension member 23 may be two different structures. The first guide member 31 and the extension member 23 may be connected together using a detachable connection or a non-detachable connection. Removable connection methods include, but are not limited to, snap connections or bolt connections; non-detachable connection methods include, but are not limited to, bonding or welding.

[0071] In some embodiments, the second guide member 33 and the connector 13 are integrally formed. That is, the second guide member 33 and the connector 13 can be integrally formed to form a whole, which can improve the stability of the connection between the second guide member 33 and the connector 13. Moreover, compared to the related art in which the charging box 100 includes a metal column, the integral structure of the second guide member 33 and the connector 13 can also reduce the assembly steps of the charging box 100, thereby improving the assembly efficiency of the charging box 100.

[0072] It is understood that in other embodiments, the second guide member 33 and the connector 13 may be separate structures, that is, the second guide member 33 and the connector 13 may have two different structures. The second guide member 33 and the connector 13 may be connected together using a detachable or non-detachable connection. Removable connection methods include, but are not limited to, snap connections or bolt connections; non-detachable connection methods include, but are not limited to, bonding or welding.

[0073] In the charging box 100 of the embodiment of the present application, the lifting assembly 30 includes a first guide member 31 and a second guide member 33. The first guide member 31 is arranged on the side wall 231 of the extension member, and the second guide member 33 is arranged on the inner wall 131 of the connecting member. The first guide member 31 and the second guide member 33 cooperate with each other. On the one hand, they can limit the horizontal movement of the cover body 20 relative to the base 10, that is, prevent the cover body 20 from moving in the horizontal direction relative to the base 10. Therefore, compared with the charging box including a metal column in the related art, the setting of the first guide member 31 and the second guide member 33 can prevent the cover body 20 from loosening or shaking during the movement relative to the base 10, thereby improving the stability of the opening and closing of the charging box 100; on the other hand, it can provide guidance for the lifting and lowering movement of the cover body 20 relative to the base 10, thereby also improving the stability of the opening and closing of the charging box 100.

[0074] In addition, compared with the related art in which the metal column provides guidance for the movement of the cover 20 relative to the base 10, the production cost of the charging box 100 in this embodiment is lower, which is conducive to improving product competitiveness.

[0075] The charging box 100 is further explained below with reference to the accompanying drawings.

[0076] See also Figure 5 In some embodiments, the extension member 23 includes a first side 2311, a second side 2313, a third side 2315 and a fourth side 2317 connected in sequence, and the first guide member 31 is disposed on at least one of the first side 2311 of the extension member, the second side 2313 of the extension member, the third side 2315 of the extension member, and the fourth side 2317 of the extension member.

[0077] Exemplarily, the first guide member 31 may be disposed on opposite sides of the extension member 23. For example, the first guide member 31 may be disposed on the first side 2311 of the extension member and the third side 2315 of the extension member; or, the first guide member 31 may be disposed on the second side 2313 of the extension member and the fourth side 2317 of the extension member. This ensures the balance of the cover 20 during movement relative to the base 10, thereby improving the stability of the opening and closing of the charging box 100. In the case where the first guide member 31 is a groove and the second guide member 33 is a protrusion, the quantitative relationship between the first guide member 31 and the second guide member 33 may be one-to-one or one-to-many, that is, one first guide member 31 corresponds to one second guide member 33; or, one first guide member 31 corresponds to multiple second guide members 33.

[0078] In some embodiments, at least one first guide member 31 is provided on the first side 2311, the second side 2313, the third side 2315, or the fourth side 2317 of the extension member. That is, at least one first guide member 31 is provided on the same side of the extension member 23 (e.g., the first side 2311, the second side 2313, the third side 2315, or the fourth side 2317 of the extension member). This prevents the extension member 23 from deflecting or shaking in the connector 13 during movement of the cover 20 relative to the base 10, thereby further improving the stability of the cover 20 during movement relative to the base 10.

[0079] See also Figure 4 and Figure 5 In some embodiments, the charging box 100 further includes a button structure 40, which includes a latching member 41 and a mating member 43. The latching member 41 reciprocates between a locked position and a first unlocked position along a first direction, and is used to connect one of the base 10 and the cover 20. The mating member 43 reciprocates between a locked position and a second unlocked position along a second direction, and is used to connect the other of the base 10 and the cover 20. When the latching member 41 and the mating member 43 are in the locked position, the latching member 41 and the mating member 43 are engaged with each other, the first direction (Z1 / Z2) is the same as the lifting direction of the cover 20, and the second direction (X1 / X2) intersects with the first direction (Z1 / Z2). Therefore, compared with the charging box in the related art, the provision of the button structure 40 can prevent the relative movement between the cover 20 and the base 10 from being unstable due to changes in the magnetic attraction force, thereby improving the stability of the charging box 100.

[0080] Furthermore, in some embodiments, the button structure 40 further includes a reset member 47 , which is connected between the fitting member 43 and the base 10 or the cover 20 , and is used to keep the fitting member 43 in the locked position.

[0081] In some embodiments, the engaging member 41 is connected to the cover 20, the fitting member 43 is connected to the base 10, and the reset member 47 is connected between the fitting member 43 and the base 10. In other embodiments, the engaging member 41 is connected to the base 10, the fitting member 43 is connected to the cover 20, and the reset member 47 is connected between the fitting member 43 and the cover 20. The embodiments of this application are described only by taking the example of the engaging member 41 being connected to the cover 20, the fitting member 43 being connected to the base 10, and the reset member 47 being connected between the fitting member 43 and the base 10.

[0082] Specifically, please combine Figure 1In some embodiments, when the engaging member 41 and the mating member 43 are in the locked position, the engaging member 41 and the mating member 43 are engaged with each other, in which case the cover body 20 can press the earphone 200; when the engaging member 41 is in the first unlocked position and the mating member 43 is in the second unlocked position, the engaging member 41 and the mating member 43 are released from the engagement, in which case the cover body 20 can release the earphone 200.

[0083] It is understood that in some embodiments, the reciprocating movement of the mating member 43 along the second direction (X1 / X2) between the locked position and the second unlocked position requires manual intervention, i.e., manually switching the mating member 43 between the locked position and the second unlocked position along the second direction (X1 / X2); or manually switching the mating member 43 between the locked position and the second unlocked position along the second direction (X1 / X2) with the aid of a tool. For example, when a user applies force to the mating member 43, the mating member 43 can move relative to the base 10 along the second direction (X1 / X2) from the locked position to the second unlocked position; when the user does not apply force to the mating member 43, the mating member 43 can move from the second unlocked position to the locked position along the second direction (X1 / X2) under the action of the reset member 47. When the fitting 43 moves along the second direction (X1 / X2), the base 10 does not move along the second direction (X1 / X2) with the fitting 43. In other words, the fitting 43 can move relative to the base 10 along the second direction (X1 / X2).

[0084] The reciprocating movement of the engaging member 41 along the first direction (Z1 / Z2) between the locked position and the first unlocked position requires manual intervention, i.e., manually switching the engaging member 41 along the first direction (Z1 / Z2) between the locked position and the first unlocked position; or manually switching the engaging member 41 along the first direction (Z1 / Z2) between the locked position and the first unlocked position with the aid of a tool. For example, when a user applies force to the engaging member 41, the engaging member 41 can move along the first direction (Z1 / Z2) from the first unlocked position to the locked position; when the user does not apply force to the engaging member 41 and the mating member 43 is in the second unlocked position, the engaging member 41 can move along the first direction (Z1 / Z2) from the locked position to the first unlocked position. When the engaging member 41 moves along the first direction (Z1 / Z2), the cover 20 moves along the first direction (Z1 / Z2) with the engaging member 41.

[0085] It should be noted that, in one example, the first direction (Z1 / Z2) and the second direction (X1 / X2) are perpendicular. For example, the first direction (Z1 / Z2) may be the height direction (Z1 / Z2) of the charging box 100. In other examples, as long as the first direction (Z1 / Z2) and the second direction (X1 / X2) intersect, the angle between the two may be any angle between (0°, 180°), for example, the angle between the two may be 15°, 30°, 45°, 60°, 75°, 100°, 115°, 120°, or 135°, etc. In the embodiment of the present application, only the first direction (Z1 / Z2) and the second direction (X1 / X2) being perpendicular is used as an example for illustration.

[0086] See also Figure 3 and Figure 4 In some embodiments, the cover body 20 can switch between a clamping position and a release position relative to the base 10. When the cover body 20 is in the clamping position, the locking member 41 and the matching member 43 are in the locked position. When the cover body 20 is in the release position, the locking member 41 is in the first unlocking position and the matching member 43 is in the second unlocking position.

[0087] Specifically, in some embodiments, the pressing position may be: along the lifting direction of the cover 20 (the same as the height direction (Z1 / Z2) of the charging box 100), the cover 20 can move downward relative to the base 10 (the cover 20 moves relative to the base 10 along the direction from the cover 20 to the base 10) to the extreme position; the release position may be: along the lifting direction of the cover 20, the cover 20 can move upward relative to the base 10 (the cover 20 moves relative to the base 10 along the direction from the base 10 to the cover 20) to the extreme position.

[0088] More specifically, please combine Figure 1 In some embodiments, when the cover 20 is in the pressed position, it can press the earphones 200, thereby limiting the position of the earphones 200 and preventing the earphones 200 from moving or shaking in the charging box 100, thereby improving the stability of the earphones 200 stored in the charging box 100. At the same time, the cover 20 in the pressed position can also prevent the earphones 200 from moving or shaking in the charging box 100, which may cause poor contact between the charging end (i.e., the second electrical connector) of the earphones 200 and the charging end (i.e., the first electrical connector 15) of the charging box 100, thereby improving the stability of the charging of the earphones 200 by the charging box 100 and ensuring the normal function of the charging function and / or signal transmission function. When the cover 20 is in the released position, the earphones 200 can be placed in the charging box 100; or the earphones 200 can be taken out of the charging box 100.

[0089] Further, see Figures 3 to 5In some embodiments, the cover 20 and the base 10 together form an earphone compartment 201 for accommodating the earphone 200 .

[0090] Specifically, in some embodiments, when the engaging member 41 moves from the locked position to the first unlocked position and the mating member 43 moves from the locked position to the second unlocked position, the cover body 20 switches from the pressed position to the released position, and the size of the earphone compartment 201 in the height direction (Z1 / Z2) of the charging box 100 increases. In this case, the earphone 200 can be placed in the earphone compartment 201; or, the earphone 200 can be taken out of the earphone compartment 201; when the engaging member 41 moves from the first unlocked position to the locked position and the mating member 43 moves from the second unlocked position to the locked position, the cover body 20 switches from the released position to the pressed position, and the size of the earphone compartment 201 in the height direction (Z1 / Z2) of the charging box 100 decreases. In this case, the cover body 20 can press the charging compartment of the earphone 200 in the earphone compartment 201, and the charging box 100 can charge the earphone 200.

[0091] In some embodiments, the earphone compartment 201 includes a first side 2011, a second side 2013, a third side 2015 and a fourth side 2017 connected in sequence, and at least one of the first side 2011, the second side 2013, the third side 2015 and the fourth side 2017 of the earphone compartment is open to allow the earphone 200 to be placed in the earphone compartment 201.

[0092] Specifically, in some embodiments, on a plane perpendicular to the height direction (Z1 / Z2) of the charging case 100 (i.e., the first direction (Z1 / Z2)), the earphone compartment 201 includes a first side 2011, a second side 2013, a third side 2015, and a fourth side 2017, which are sequentially connected. At least one of the first side 2011, the second side 2013, the third side 2015, and the fourth side 2017 of the earphone compartment is open. Thus, when the cover 20 is raised relative to the base 10, the earphones 200 can be placed into the earphone compartment 201 through the open side (including at least one of the first side 2011, the second side 2013, the third side 2015, and the fourth side 2017 of the earphone compartment), thereby enabling the charging case 100 to charge and store the earphones 200.

[0093] In certain embodiments of the present application, the first side 2011 of the earphone compartment is closed, and the second side 2013, the third side 2015 and the fourth side 2017 of the earphone compartment are open. At this time, when the cover 20 rises relative to the base 10, the earphone 200 can be placed into the earphone compartment 201 through the second side 2013 of the earphone compartment along the direction from the second side 2013 of the earphone compartment to the fourth side 2017 of the earphone compartment; or, the earphone 200 can be placed into the earphone compartment 201 through the third side 2015 of the earphone compartment along the direction from the third side 2015 of the earphone compartment to the first side 2011 of the earphone compartment.

[0094] See also Figures 3 to 5 In some embodiments, the key structure 40 further includes an elastic member 45 connected between the base 10 and the cover 20 and extending in a first direction. A reset member 47 is connected between the mating member 43 and the base 10 and extending in a second direction. When the cover 20 is in the compressed position, the elastic member 45 has a first length and the reset member 47 is in a first state. When the cover 20 is in the released position, the elastic member 45 has a second length and the reset member 47 is in a second state, where the second length is greater than the first length.

[0095] Specifically, in some embodiments, when the cover 20 is switched from the pressed position to the released position, the size of the earphone compartment 201 in the height direction (Z1 / Z2) of the charging box 100 increases, and the second length of the elastic member 45 when the cover 20 is in the released position is greater than the first length of the elastic member 45 when the cover 20 is in the pressed position. Therefore, when the cover 20 is in the pressed position, the elastic member 45 is in a compressed state; when the cover 20 is in the released position, the elastic member 45 is in a normal state (not stretched or compressed) or a compressed state (at this time, the compression amount of the elastic member 45 is less than the compression amount of the elastic member 45 when the cover 20 is in the pressed position). Therefore, in the process of switching the cover 20 from the pressed position to the released position, the elastic member 45 can provide elastic force to the cover 20, thereby ensuring that the cover 20 can smoothly rise relative to the base 10.

[0096] In some embodiments, when the cover 20 switches from the compressed position to the released position, the reset member 47 switches sequentially between the first state, the second state, and the first state. When the cover 20 switches from the released position to the compressed position, the reset member 47 switches sequentially between the first state, the second state, and the first state. The length of the reset member 47 in the first state is different from the length of the reset member 47 in the second state.

[0097] Specifically, in some embodiments, when the reset member 47 is in the first state, the engaging member 41 and the matching member 43 are both in the locked position; when the reset member 47 is in the second state, the engaging member 41 is in the first unlocked position, and the matching member 43 is in the second unlocked position.

[0098] When the cover 20 switches from the pressed position to the released position, the reset member 47 switches sequentially between the first state, the second state, and the first state. That is, the mating member 43 switches sequentially between the locked position, the second unlocked position, and the locked position. When the mating member 43 moves from the locked position to the second unlocked position, the engagement between the mating member 43 and the engaging member 41 is released, and the engaging member 41 moves from the locked position to the first unlocked position. It is understood that the length of the reset member 47 in the first state is different from the length of the reset member 47 in the second state. In this way, the reset member 47 can generate a reset force on the mating member 43, and the reset force is used to maintain the mating member 43 in the locked position.

[0099] Furthermore, in some embodiments, when the cover body 20 is in the clamping position and the mating piece 43 is subjected to the first force, the mating piece 43 can move along the positive direction X1 of the second direction (X1 / X2), the reset piece 47 switches from the first state to the second state, and the elastic piece 45 stretches and pushes the cover body 20 to move along the upward direction of the cover body 20; when the first force disappears, the reset piece 47 switches from the second state to the first state, and the mating piece 43 moves along the reverse direction X2 of the second direction (X1 / X2) and is located below the locking piece 41.

[0100] Specifically, in some embodiments, when the mating member 43 is subjected to a first force and moves in the positive direction X1 of the second direction (X1 / X2), the reset member 47 generates a reset force, causing the mating member 43 to move from the locked position to the second unlocked position, thereby releasing the engagement between the mating member 43 and the engaging member 41. The elastic force of the elastic member 45 can push the cover 20 to move in the upward direction of the cover 20. When the first force disappears, the reset force of the reset member 47 can cause the mating member 43 to move in the negative direction X2 of the second direction (X1 / X2), that is, the reset force can cause the mating member 43 to move from the second unlocked position to the locked position. In this case, the mating member 43 is located below the engaging member 41. Thus, when the mating member 43 is subjected to the first force, the cover 20 can switch from the pressed position to the released position.

[0101] In some embodiments, when the cover body 20 is in the release position and the cover body 20 is subjected to the second force, the elastic member 45 is compressed, the cover body 20 moves along the downward direction of the cover body 20, the engaging member 41 pushes the mating member 43 to move along the positive direction X1 of the second direction (X1 / X2), and the reset member 47 switches from the first state to the second state; when the engaging member 41 is in the locked position, the mating member 43 moves along the reverse direction X2 of the second direction (X1 / X2), and the reset member 47 switches from the second state to the first state.

[0102] Specifically, in some embodiments, when the cover 20 is subjected to the second force and the cover 20 moves in the downward direction of the cover 20 (the direction from the cover 20 to the base 10), the engaging member 41 generates a thrust on the mating member 43 to push the mating member 43 to move in the positive direction X1 of the second direction (X1 / X2). At this time, the reset member 47 generates a reset force, and the mating member 43 moves from the locked position to the second unlocked position. When the engaging member 41 moves in the downward direction of the cover 20 to the locked position, the engaging member 41 does not generate a thrust on the mating member 43. The reset force of the reset member 47 can move the mating member 43 in the reverse direction X2 of the second direction (X1 / X2). That is, the reset force can move the mating member 43 from the second unlocked position to the locked position. In this case, the engaging member 41 and the mating member 43 are engaged. Thus, when the cover 20 is subjected to the second force, the cover 20 can switch from the released position to the compressed position.

[0103] See also Figures 3 to 5 In some embodiments, the first force acting on the mating member 43 is pressure, the length of the reset member 47 in the first state is greater than the length of the reset member 47 in the second state, the positive direction X1 of the second direction (X1 / X2) is toward the inside of the base 10, and the reverse direction X2 of the second direction (X1 / X2) is toward the outside of the base 10.

[0104] Specifically, please combine Figure 4 and Figure 5 In some embodiments, when the engaging member 41 and the mating member 43 are engaged, the reset member 47 is located on the side of the mating member 43 opposite the engaging member 41. In this case, the reset member 47 may be a compression spring. When the reset member 47 is in a first state, the mating member 43 is in a locked position, and the reset member 47 is in a normal state (not stretched or compressed) or in a first compressed state. When the reset member 47 is in a second state, the mating member 43 is in a second unlocked position, and the reset member 47 is in a second compressed state. The length of the reset member 47 in the first compressed state is greater than the length of the reset member 47 in the second compressed state.

[0105] See also Figure 3 and Figure 7In some embodiments, the first force acting on the mating member 43 is a tensile force, the length of the reset member 47 in the first state is less than the length of the reset member 47 in the second state, the positive direction X1 of the second direction (X1 / X2) is toward the outside of the base 10, and the reverse direction X2 of the second direction (X1 / X2) is toward the inside of the base 10.

[0106] Specifically, please combine Figure 7 In some embodiments, when the engaging member 41 and the mating member 43 are engaged, the reset member 47 is located on the side of the mating member 43 opposite the engaging member 41. In this case, the reset member 47 may be a tension spring. When the reset member 47 is in a first state, the mating member 43 is in a locked position, and the reset member 47 is in a normal state (not stretched or compressed) or in a first stretched state. When the reset member 47 is in a second state, the mating member 43 is in a second unlocked position, and the reset member 47 is in a second stretched state. The length of the reset member 47 in the first stretched state is less than the length of the reset member 47 in the second stretched state.

[0107] See also Figures 3 to 5 , and combined with Figure 6 or Figure 7 In some embodiments, the mating piece 43 includes a mating body 431 and a hook portion 433, and the engaging piece 41 includes a engaging body 411 and an engaging portion 413. The hook portion 433 cooperates with the engaging portion 413 to enable the mating piece 43 to be engaged with the engaging piece 41.

[0108] Specifically, in some embodiments, when the engaging member 41 and the matching member 43 are both in the locked position, the hook portion 433 cooperates with the engaging portion 413; when the engaging member 41 is in the first unlocked position and the matching member 43 is in the second unlocked position, the hook portion 433 is disengaged from the engaging portion 413.

[0109] In some embodiments, the mating body 431 and the hook portion 433 are an integrated structure, that is, the mating body 431 and the hook portion 433 can be formed into a whole by an integrated molding method, which can improve the stability of the connection between the mating body 431 and the hook portion 433, and prevent the hook portion 433 from falling off from the mating body 431 when the hook portion 433 is mated with the locking portion 413, thereby ensuring the stability and reliability of the key structure 40.

[0110] In other embodiments, the mating body 431 and the hook portion 433 are separate structures, that is, the mating body 431 and the hook portion 433 are two different structures. In one example, the mating body 431 and the hook portion 433 can be connected together using a detachable connection method, and the detachable connection method includes but is not limited to a snap connection or a bolt connection. In another example, the mating body 431 and the hook portion 433 can be connected together using a non-detachable connection method, and the non-detachable connection method includes but is not limited to bonding or welding. It is understood that the connection method between the engaging body 411 and the engaging portion 413 is basically the same as the connection method between the mating body 431 and the hook portion 433, and will not be described in detail here.

[0111] Furthermore, in some embodiments, the engaging portion 413 is provided with a first inclined surface 4131 , and the hook portion 433 is provided with a second inclined surface 4331 . When the cover 20 switches from the release position to the compression position, the first inclined surface 4131 and the second inclined surface 4331 collide with each other.

[0112] If the first inclined surface 4131 is not provided on the engaging portion 413, and the second inclined surface 4331 is not provided on the hook portion 433, then when the engaging portion 413 moves along the downward direction of the cover 20 so that the engaging portion 413 and the hook portion 433 come into contact, the engaging portion 413 can only generate a thrust on the hook portion 433 along the first direction (Z1 / Z2) (i.e., the lifting direction of the charging box 100), and this thrust cannot push the hook portion 433 to move along the second direction (X1 / X2). Therefore, the provision of the first inclined surface 4131 and the second inclined surface 4331 enables the engaging portion 413 to generate a thrust on the hook portion 433 when the first inclined surface 4131 and the second inclined surface 4331 come into contact, and the component of this thrust in the second direction (X1 / X2) can push the hook portion 433 to move along the second direction (X1 / X2).

[0113] Specifically, in some embodiments, the angle between the first inclined surface 4131 and the positive direction X1 of the second direction (X1 / X2) is a first acute angle, and the angle between the second inclined surface 4331 and the positive direction X1 of the second direction (X1 / X2) is also a second acute angle. It should be noted that in some embodiments, the first acute angle and the second acute angle may be the same or different.

[0114] In some embodiments, the engaging portion 413 is provided with a first flat surface 4133, and the hook portion 433 is provided with a second flat surface 4333. When the cover 20 is in the compressed position, the first flat surface 4133 abuts against the second flat surface 4333. Both the first flat surface 4133 and the second flat surface 4333 are perpendicular to the first direction (Z1 / Z2). Thus, the abutment between the first flat surface 4133 and the second flat surface 4333 enables a snap-fit ​​engagement between the engaging portion 413 and the mating portion, thereby limiting the lifting and lowering of the cover 20 relative to the base 10.

[0115] See also Figure 4 and Figure 5 In some embodiments, a first guide member 103 is provided on the base 10 or the cover 20. The first guide member 103 extends along a first direction. The first guide member 103 cooperates with the elastic member 45 and is used to guide the expansion and contraction of the elastic member 45. The first guide member 103 can limit and guide the deformation of the elastic member 45, reducing or even preventing deformation of the elastic member 45 in directions other than the first direction (Z1 / Z2), ensuring that the elastic member 45 can provide an effective elastic force on the cover 20 to switch the cover 20 from the compressed position to the released position. It should be noted that the number of first guide members 103 and elastic members 45 is one-to-one, that is, one first guide member 103 corresponds to one elastic member 45.

[0116] In some embodiments, the first guide member 103 is a column, and the elastic member 45 is sleeved on the side wall of the column.

[0117] Specifically, in one example, the outer contour of the side wall of the cylinder is a continuous, uninterrupted, closed ring. Exemplarily, the cylinder may be cylindrical, in which case the outer contour of the side wall of the cylinder is circular. In another example, the outer contour of the side wall of the cylinder is a non-closed ring with at least one discontinuous opening. Thus, when the elastic member 45 is sleeved on the side wall of the cylinder, the contact area between the elastic member 45 and the side wall of the cylinder is small, thereby reducing the friction between the elastic member 45 and the cylinder, and ensuring the stability of the elastic member 45 in the expansion and contraction along the first direction (Z1 / Z2). Exemplarily, at least one groove is provided on the cylinder, and the groove is recessed from the outer side of the side wall of the cylinder toward the center of the cylinder.

[0118] In other embodiments, the first guide member 103 is a column, and a receiving space is defined in the column, and the elastic member 45 is received in the receiving space.

[0119] Specifically, in one example, the inner contour of the sidewall of the cylinder is a continuous, uninterrupted, closed ring. For example, the accommodating space may be cylindrical, in which case the inner contour of the sidewall of the cylinder is circular. In another example, the inner contour of the sidewall of the cylinder is a non-closed ring with at least one discontinuity. Thus, when the elastic member 45 is accommodated within the accommodating space, the contact area between the elastic member 45 and the sidewall of the cylinder is small, thereby reducing friction between the elastic member 45 and the cylinder and ensuring the stability of the elastic member 45 when it expands and contracts along the first direction (Z1 / Z2).

[0120] In certain embodiments, a second guide member 101 is provided on the base 10 or the mating member 43. The second guide member 101 extends along the second direction. The second guide member 101 cooperates with the reset member 47 and is used to guide the extension and retraction of the reset member 47. The second guide member 101 can limit and guide the deformation of the reset member 47, reducing or even preventing deformation of the reset member 47 in directions other than the second direction (X1 / X2), ensuring that the reset member 47 can provide an effective restoring force on the mating member 43, thereby maintaining the mating member 43 in the locked position. It should be noted that the number of second guide members 101 and reset members 47 is one-to-one, i.e., one second guide member 101 corresponds to one reset member 47.

[0121] In some embodiments, the second guide member 101 is a column, and the reset member 47 is sleeved on the side wall of the column.

[0122] Specifically, in one example, the outer contour of the sidewall of the cylinder is a continuous, uninterrupted, closed ring. For example, the cylinder may be cylindrical, in which case the outer contour of the sidewall of the cylinder is circular. In another example, the outer contour of the sidewall of the cylinder is a non-closed ring with at least one discontinuity. Thus, when the reset member 47 is sleeved on the sidewall of the cylinder, the contact area between the reset member 47 and the sidewall of the cylinder is small, thereby reducing friction between the reset member 47 and the cylinder and ensuring the stability of the reset member 47 when it is extended and retracted along the second direction (X1 / X2).

[0123] In other embodiments, the second guide member 101 is a column, and a receiving space is defined in the column, and the reset member 47 is received in the receiving space.

[0124] Specifically, in one example, the inner contour of the sidewall of the cylinder is a continuous, uninterrupted, closed ring. For example, the accommodating space may be cylindrical, in which case the inner contour of the sidewall of the cylinder is circular. In another example, the inner contour of the sidewall of the cylinder is a non-closed ring with at least one discontinuity. Thus, when the elastic member 45 is accommodated within the accommodating space, the contact area between the elastic member 45 and the sidewall of the cylinder is small, thereby reducing friction between the elastic member 45 and the cylinder and ensuring the stability of the elastic member 45 when it expands and contracts along the first direction (Z1 / Z2).
