Description

Technical Field

[0001] This application relates to the technical field of electronic devices, and more particularly, to a charging case and a headphone system. Background Art

[0002] In related technologies, users usually use a charging case to charge or store headphones, etc. For example, when the headphone battery is low or not in use, the user can place it in the charging case. The charging case includes a base and a cover, and the cover can be lifted and lowered relative to the base to facilitate the taking and placing of the headphones. However, if there is no limit to the lifting and lowering stroke of the cover relative to the base, when the force applied by the user to the charging case is too large, the cover may exert too much impact force on the base or too much pressing force on the headphones, resulting in damage to the charging case and / or the headphones. Summary of the Invention

[0003] Embodiments of this application provide a charging case and a headphone system to solve at least one of the above-mentioned technical problems.

[0004] The charging case provided by the embodiments of this application includes a base, a cover, a charging battery, and a limiting component. The base is provided with a bearing surface for bearing the component to be charged. The cover is connected to the base and can be lifted and lowered relative to the base to switch between a pressing position and a release position. When the cover is in the pressing position, the cover presses the component to be charged onto the bearing surface. The charging battery is arranged in the base. The limiting component is arranged on the cover and / or the base, and the limiting component is used to limit the lifting and lowering stroke of the cover relative to the base.

[0005] The headphone system provided by the embodiments of this application includes headphones and a charging case, and the charging case is used to charge the headphones. The charging case includes a base, a cover, a charging battery, and a limiting component. The base is provided with a bearing surface for bearing the component to be charged. The cover is connected to the base and can be lifted and lowered relative to the base to switch between a pressing position and a release position. When the cover is in the pressing position, the cover presses the component to be charged onto the bearing surface. The charging battery is arranged in the base. The limiting component is arranged on the cover and / or the base, and the limiting component is used to limit the lifting and lowering stroke of the cover relative to the base.

[0006] In the charging case and the headphone system according to the embodiments of this application, the arrangement of the limiting component can limit the lifting and lowering stroke of the cover relative to the base, so as to avoid the cover exerting too much impact force on the base or too much pressing force on the headphones when the force applied by the user to the charging case is too large, thereby reducing the possibility of damage to the charging case and / or the headphones and extending the service life of the charging case and the headphones.

These are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the present application. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0040] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected" and "coupled" should be understood in a broad sense. In one example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection, an electrical connection or may communicate with each other; it may be directly connected or indirectly connected through an intermediate medium, and may be the internal communication of two elements or the interaction relationship between two elements.

[0041] Please refer to Figure 1 , the headphone system 300 provided by the embodiment of the present application includes a component to be charged and a charging case 100. The charging case 100 is used to charge the component to be charged. It should be noted that in some embodiments, the component to be charged includes, but is not limited to, headphones, watches, bracelets, game controllers, cameras, etc. In the embodiments shown below, only the headphones 200 are taken as an example for the component to be charged for illustration.

[0042] Among them, since the headphone system 300 in this embodiment includes the charging case 100, it can be understood that the headphone system 300 at least includes the same beneficial effects as the charging case 100. Therefore, for the beneficial effects of the headphone system 300, please refer to the beneficial effects of the charging case 100 introduced below.

[0043] In some embodiments of the present application, the device to be charged includes an air-conduction earphone and a bone-conduction earphone. Among them, the air-conduction earphone is an earphone 200 that transmits sound through air vibration. The bone-conduction earphone is an earphone 200 that converts sound into different mechanical vibrations and transmits sound waves through the human skull, bony labyrinth, endolymph of the inner ear, spiral organ, auditory center, etc. It can be understood that the earphone 200 can be worn on the user's ear and can be used in cooperation 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.

[0044] It should be noted that the user's ear includes parts such as the external auditory canal, concha, cymba conchae, triangular fossa, helix, and antitragus. Among them, parts such as the concha, cymba conchae, and triangular fossa have a certain depth and volume in three-dimensional space. The external auditory canal is a curved tube that extends medially from the external acoustic meatus deep in the concha to the tympanic membrane.

[0045] Furthermore, in some 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 in 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 on the front side of the ear when the earphone 200 is in a worn state. At this time, 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 concha, cymba conchae, and triangular fossa when the earphone 200 is in a worn state. It should be noted that in the following embodiments, only the case where the earphone 200 is a bone-conduction earphone is taken as an example for illustration.

[0046] Even further, in some embodiments, the earphone 200 includes a battery compartment 220, a control compartment 230, a first ear hook assembly 240, a second ear hook assembly 250, and a rear hook assembly 260 disposed between the first ear hook assembly 240 and the second ear hook assembly 250. The first ear hook assembly 240 and the second ear hook assembly 250 are respectively hung on the left ear and the right ear. The battery compartment 220 can be disposed between the first ear hook assembly 240 and the rear hook assembly 260, and the control compartment 230 can be disposed between the second ear hook assembly 250 and the rear hook assembly 260. Among them, both the first transducer assembly 2101 and the second transducer assembly 2103 are used to convert electrical signals into mechanical vibrations so that the user can hear sound.

[0047] Please combine Figure 4, in some embodiments, the charging case 100 includes a rechargeable battery 110 and a circuit board 120. When the earphone 200 is placed in the charging case 100, the circuit board 120 can deliver the electrical energy of the rechargeable battery 110 to the earphone 200 to charge the earphone 200.

[0048] Further, please refer to Figure 2 and Figure 3 , in some embodiments, the charging case 100 is provided with a first electrical connector 17, and the earphone 200 is provided with a second electrical connector 280. When the earphone 200 is placed in the charging case 100, the first electrical connector 17 and the second electrical connector 280 are electrically connected.

[0049] Specifically, in some embodiments, when the first electrical connector 17 and the second electrical connector 280 are electrically connected, functions such as power transmission and data transmission can be achieved between the charging case 100 and the earphone 200. For example, when the first electrical connector 17 and the second electrical connector 280 are electrically connected, the circuit board 120 can transmit the electrical energy of the rechargeable battery 110 to the battery compartment 220 of the earphone 200 through the first electrical connector 17 and the second electrical connector 280, thereby charging the earphone 200.

[0050] Furthermore, in some embodiments, there are multiple first electrical connectors 17 and multiple second electrical connectors 280. When the earphone 200 is placed in the charging case 100, the multiple first electrical connectors 17 and the multiple second electrical connectors 280 are electrically connected in one-to-one correspondence.

[0051] Specifically, in some embodiments, a part of the multiple first electrical connectors 17 is used for power transmission, and another part is used for signal transmission; correspondingly, a part of the multiple second electrical connectors 280 is used for power transmission, and another part is used for signal transmission. Among them, the multiple first electrical connectors 17 are arranged side by side on the charging case 100. In this way, compared with the case where the multiple first electrical connectors 17 are not arranged side by side on the charging case 100, on the one hand, the space occupied by the first electrical connectors 17 can be reduced, making the structure more compact and conducive to the miniaturization of the charging case 100; on the other hand, it is convenient to align the first electrical connectors 17 and the second electrical connectors 280, improving the convenience of electrical connection.

[0052] Please refer to Figure 1 , Figure 3 and Figure 4, the charging case 100 provided by the embodiment of the present application includes a base 10, a cover body 20, and a limiting component 30. The base 10 is provided with a bearing surface 103 for bearing the component to be charged. The cover body 20 is connected to the base 10 and can move up and down relative to the base 10 to switch between a pressing position and a releasing position. When the cover body 20 is in the pressing position, the cover body 20 presses the component to be charged onto the bearing surface 103. The limiting component 30 is arranged on the cover body 20 and / or the base 10, and the limiting component 30 is used to limit the lifting stroke of the cover body 20 relative to the base 10.

[0053] Among them, the base 10 is a structure in the charging case 100 for bearing the earphone 200. In some embodiments of the present application, the charging battery 110 and the circuit board 120 are both arranged in the base 10. In this way, the weight of the base 10 can be increased, and the possibility of the charging case 100 tipping over when the earphone 200 is stored in the charging case 100 can be reduced. The material of the base 10 includes but is not limited to plastics, aluminum alloys, copper, iron, steel, and carbon fiber composite materials, etc. Exemplarily, the material of the base 10 is plastic, so that the charging case 100 can be made lighter and more convenient for users to carry. In some embodiments, the bearing surface 103 can be the surface on the base 10 that abuts against the earphone 200 (the component to be charged). Among them, the bearing surface 103 can match the outer contour of the earphone 200, that is, the shape, size, and contour of the bearing surface 103 can be exactly the same or almost exactly the same as the shape, size, and contour of the side of the earphone 200 that abuts against the bearing surface 103. In this way, it is convenient for the installation and positioning of the earphone 200 on the charging case 100, and the stability of the earphone 200 stored in the charging case 100 can also be improved.

[0054] The cover body 20 is a structure in the charging case 100 that can cooperate with the base 10 to limit the earphone 200. The material of the cover body 20 includes but is not limited to plastics, aluminum alloys, copper, iron, steel, and carbon fiber composite materials, etc. Exemplarily, the material of the cover body 20 is plastic, so that the charging case 100 can be made lighter and more convenient for users to carry. It can be understood that the material of the cover body 20 can be the same as or different from the material of the base 10. Among them, the cover body 20 can move up and down relative to the base 10, so that the applicability of the charging case 100 can be improved, and it can prevent the charging case 100 from being unable to charge the earphone 200 due to the large size of the bone conduction earphone.

[0055] In some embodiments, the charging case 100 may include a lifting component 40. The lifting component 40 is arranged on the base 10 and / or the cover body 20. The lifting component 40 is used to move the cover body 20 up and down relative to the base 10 to switch between a pressing position and a releasing position. When the cover body 20 is in the pressing position, the cover body 20 presses the earphone 200; when the cover body 20 is in the releasing position, the cover body 20 releases the earphone 200.

[0056] Among them, the pressing position can be: along the lifting direction of the cover body 20 (the same as the height direction (Z1 / Z2) of the charging case 100), the limit position that the lifting assembly 40 enables the cover body 20 to move downward relative to the base 10 (the cover body 20 moves relative to the base 10 along the direction from the cover body 20 to the base 10); the release position can be: along the lifting direction of the cover body 20, the limit position that the lifting assembly 40 enables the cover body 20 to move upward relative to the base 10 (the cover body 20 moves relative to the base 10 along the direction from the base 10 to the cover body 20). It can be understood that in the normal state of the charging case 100 (for example, when the charging case 100 does not accommodate the earphone 200), the cover body 20 can be in the pressing position, so as to reduce the space occupied by the charging case 100 and facilitate the user to carry.

[0057] Specifically, in some embodiments, when the cover body 20 is in the pressing position, the cover body 20 can press the earphone 200, so as to realize the limit of the earphone 200, prevent the earphone 200 from moving or shaking in the charging case 100, and improve the stability of the earphone 200 stored in the charging case 100. At the same time, when the cover body 20 is in the pressing position, it can also prevent the earphone 200 from moving or shaking in the charging case 100, resulting in poor contact between the charging end (i.e., the second electrical connector 280) of the earphone 200 and the charging end (i.e., the first electrical connector 17) of the charging case 100, thereby improving the charging stability of the charging case 100 for the earphone 200 and ensuring the normal realization of the charging function and / or signal transmission function. When the cover body 20 is in the release position, the earphone 200 can be put into the charging case 100; or, the earphone 200 can be taken out of the charging case 100.

[0058] The limiting assembly 30 is a structure in the charging case 100 for limiting the lifting of the cover body 20 relative to the base 10. In some embodiments of the present application, the limiting assembly 30 can limit the movement stroke of the cover body 20 moving downward relative to the base 10. Thus, in the direction from the cover body 20 to the base 10, the farthest position that the cover body 20 can move relative to the base 10 is the pressing position; the limiting assembly 30 can also limit the movement stroke of the cover body 20 moving upward relative to the base 10. Thus, in the direction from the base 10 to the cover body 20, the farthest position that the cover body 20 can move relative to the base 10 is the release position.

[0059] In the charging case 100 of the embodiment of the present application, the setting of the limiting assembly 30 can limit the lifting stroke of the cover body 20 relative to the base 10. Thus, when the force applied by the user to the charging case 100 is too large, it can avoid the cover body 20 generating too large an impact force on the base 10 or too large a pressing force on the earphone 200, thereby reducing the possibility of damage to the charging case 100 and / or the earphone 200 and prolonging the service life of the charging case 100 and the earphone 200.

[0060] In addition, the provision of the limiting component 30 can also prevent the cover body 20 from rising too far relative to the base 10, resulting in the cover body 20 falling off the base 10, thereby ensuring the stability and reliability of the charging box 100 during operation.

[0061] The charging box 100 will be further explained below with reference to the accompanying drawings.

[0062] Please refer to Figure 1 、 Figure 3 and Figure 4 In some embodiments, the cover body 20 includes a main body 21 and an extension member 23. The extension member 23 extends from the main body 21 towards the base 10. The base 10 includes a base body 11 and a connecting member 13. The connecting member 13 extends from the base body 11 towards the cover body 20. A part of the extension member 23 extends into the connecting member 13 and can move up and down relative to the connecting member 13 to selectively release or press the earphone 200.

[0063] Specifically, in some embodiments, the connecting member 13 may be provided with a moving space. A part of the extension member 23 extends into the moving space and can move relative to the connecting member 13 within the moving space. Among them, the provision of the moving space can guide and limit the up and down movement of the extension member 23, preventing the extension member 23 from shifting and getting stuck during the up and down movement, thereby improving the stability of the cover body 20 moving up and down relative to the base 10.

[0064] In some embodiments, the main body 21 and the extension member 23 are of an integral structure, that is, the main body 21 and the extension member 23 can be formed as a whole by an integral molding method, which can improve the connection stability between the main body 21 and the extension member 23. In other embodiments, the main body 21 and the extension member 23 are of a split structure, that is, the main body 21 and the extension member 23 are two different structures. In one example, the main body 21 and the extension member 23 can be combined together by a detachable connection method, and the detachable connection method includes but is not limited to snap connection or bolt connection, etc. In another example, the main body 21 and the extension member 23 can be combined together by a non-detachable connection method, and the non-detachable connection method includes but is not limited to bonding or welding, etc. It can be understood that the connection method between the base body 11 and the connecting member 13 is basically the same as that between the main body 21 and the extension member 23, and will not be elaborated here.

[0065] Furthermore, in some embodiments, the rechargeable battery 110 and the circuit board 120 are both disposed within the base body 11. Among them, the base body 11 includes a base main body 111 and an upper cover 113. The connecting member 13 extends from the upper cover 113 towards the cover body 20. The base main body 111 and the upper cover 113 are detachably connected, which facilitates the installation of the rechargeable battery 110 and the circuit board 120 within the base body 11.

[0066] Please combine Figure 3 and Figure 4, in some embodiments, the cover 20 and the base 10 together form a headphone compartment 101 for accommodating the headphones 200. It should be noted that, in some embodiments, a part of the first electrical connector 17 penetrates the bearing surface 103 and extends into the headphone compartment 101. When the headphones 200 are placed on the bearing surface 103, that is, when the headphones 200 are accommodated in the headphone compartment 101, the first electrical connector 17 is electrically connected to the second electrical connector 280. In other words, when the headphones 200 are placed on the bearing surface 103, the multiple first electrical connectors 17 and the multiple second electrical connectors 280 are electrically connected in a one-to-one correspondence.

[0067] Specifically, in some embodiments, the main body 21, the extension 23, the connector 13 and the base 11 can jointly enclose the headphone compartment 101. Among them, when the cover 20 rises relative to the base 10, the size of the headphone compartment 101 in the height direction (Z1 / Z2) of the charging case 100 increases, and the cover 20 switches from the pressing position to the release position. In this case, the headphones 200 can be put into the headphone compartment 101; or, the headphones 200 can be taken out from the headphone compartment 101; when the cover 20 descends relative to the base 10, the size of the headphone compartment 101 in the height direction (Z1 / Z2) of the charging case 100 decreases, and the cover 20 switches from the release position to the pressing position. In this case, the cover 20 can press the headphones 200 in the headphone compartment 101, and the charging case 100 can charge the headphones 200.

[0068] In some embodiments, the headphone compartment 101 includes a first side 1011, a second side 1013, a third side 1015 and a fourth side 1017 that are connected in sequence. At least one of the first side 1011, the second side 1013, the third side 1015 and the fourth side 1017 of the headphone compartment is open to allow the headphones 200 to be put into the headphone compartment 101.

[0069] Specifically, in some embodiments, in a direction perpendicular to the height direction (Z1 / Z2) of the charging case 100, the headphone compartment 101 includes a first side 1011, a second side 1013, a third side 1015 and a fourth side 1017 that are connected in sequence. Among them, at least one of the first side 1011, the second side 1013, the third side 1015 and the fourth side 1017 of the headphone compartment is open. Thus, when the cover 20 rises relative to the base 10, the headphones 200 can be put into the headphone compartment 101 through the open side (including at least one of the first side 1011, the second side 1013, the third side 1015 and the fourth side 1017 of the headphone compartment), so that the charging case 100 can charge and store the headphones 200.

[0070] In some embodiments of the present application, the first side 1011 of the earphone compartment is closed, and the second side 1013, the third side 1015, and the fourth side 1017 of the earphone compartment are open. At this time, when the cover 20 rises relative to the base 10, in the direction from the second side 1013 to the fourth side 1017 of the earphone compartment, the earphone 200 can be placed into the earphone compartment 101 through the second side 1013 of the earphone compartment; or, in the direction from the third side 1015 to the first side 1011 of the earphone compartment, the earphone 200 can be placed into the earphone compartment 101 through the third side 1015 of the earphone compartment.

[0071] In some embodiments, the extension member 23 is disposed on the side edge of the main body 21, and the connecting member 13 is disposed on the side edge of the seat body 11. Thus, compared with the case where the extension member 23 is disposed at a position away from the side edge of the main body 21 (such as the central position of the main body 21), and the connecting member 13 is disposed at a position away from the side edge of the seat body 11 (such as the central position of the seat body 11), the size of the earphone compartment 101 is larger, which is convenient for the installation of the earphone 200 on the charging box 100 and improves the applicability of the charging box 100.

[0072] Please refer to Figure 4 , in some embodiments, the limiting assembly 30 includes a limiting member and a clamping member 33. One of the limiting member and the clamping member 33 is disposed on the inner wall of the base 10, and the other is disposed on the outer wall of the cover 20. The limiting member and the clamping member 33 cooperate to limit the upward and downward travel of the cover 20 relative to the base 10.

[0073] It should be noted that in some embodiments, one of the limiting member and the clamping member 33 is disposed on the inner wall of the base 10, and the other is disposed on the outer wall of the cover 20, that is: one of the limiting member and the clamping member 33 is disposed on the inner wall 131 of the connecting member 13, and the other is disposed on the outer wall of the extension member 23.

[0074] Specifically, in some embodiments, the limiting member and the clamping member 33 cooperate to limit the upward movement travel of the cover 20 relative to the base 10, so that the farthest position that the cover 20 can move upward relative to the base 10 is the release position, preventing the upward travel of the cover 20 relative to the base 10 from being too large and causing the cover 20 to fall off the base 10, thereby ensuring the stability and reliability of the charging box 100 during operation; the limiting member and the clamping member 33 cooperate to limit the downward movement travel of the cover 20 relative to the base 10, so that the farthest position that the cover 20 moves downward relative to the base 10 is the pressing position, avoiding the cover 20 from continuing to descend under the action of the impact force generated when the charging box 100 collides during a fall, resulting in the cover 20 exerting too large an impact force on the base 10, thereby reducing the possibility of damage to the charging box 100 and extending the service life of the charging box 100.

[0075] In some embodiments, the limiting member is disposed on the inner wall of the base 10, and the engaging member 33 is disposed on the outer wall of the cover 20. Specifically, the limiting member is disposed on the connecting member 13, and the engaging member 33 is disposed on the extending member 23.

[0076] Further, in some embodiments, when the limiting member is disposed on the inner wall of the base 10 and the engaging member 33 is disposed on the outer wall of the cover 20, the limiting member and the base 10 are of an integral structure or a split structure, and the engaging member 33 and the cover 20 are of an integral structure or a split structure.

[0077] Specifically, the limiting member and the base 10 are of an integral structure, that is, the limiting member and the connecting member 13 can be integrally formed as a whole by an integral molding method, so as to improve the connection strength between the limiting member and the connecting member 13, prevent the limiting member from falling off the connecting member 13 when the limiting member cooperates with the engaging member 33, and ensure the stability and reliability of the operation of the limiting assembly 30. The limiting member and the base 10 are of a split structure, that is, the limiting member and the connecting member 13 are two different structures, and the limiting member and the connecting member 13 can be combined together by a detachable connection method or a non-detachable connection method. Among them, the detachable connection methods include but are not limited to snap connection or bolt connection; the non-detachable connection methods include but are not limited to bonding or welding, etc.

[0078] It can be understood that the connection and cooperation method between the engaging member 33 and the cover 20 is basically the same as the connection and cooperation method between the limiting member and the base 10, and will not be described repeatedly here.

[0079] In some other embodiments, the limiting member is disposed on the outer wall of the cover 20, and the engaging member 33 is disposed on the inner wall of the base 10. Specifically, the limiting member is disposed on the extending member 23, and the engaging member 33 is disposed on the connecting member 13.

[0080] Further, in some embodiments, when the engaging member 33 is disposed on the inner wall of the base 10 and the limiting member is disposed on the outer wall of the cover 20, the engaging member 33 and the base 10 are of an integral structure or a split structure, and the limiting member and the cover 20 are of an integral structure or a split structure.

[0081] Specifically, the limiting member and the cover body 20 are of an integral structure, that is, the limiting member and the extension member 23 can be integrally formed into a whole. In this way, the connection strength between the limiting member and the extension member 23 can be improved, preventing the limiting member from falling off the extension member 23 when the limiting member cooperates with the clamping member 33, and ensuring the stability and reliability of the operation of the limiting component 30. The limiting member and the cover body 20 are of a split structure, that is, the limiting member and the extension member 23 are two different structures, and the limiting member and the extension member 23 can be combined together by a detachable connection method or a non-detachable connection method. Among them, the detachable connection methods include but are not limited to snap connection or bolt connection; the non-detachable connection methods include but are not limited to bonding or welding, etc.

[0082] It can be understood that the connection and cooperation method between the clamping member 33 and the base 10 is basically the same as the connection and cooperation method between the limiting member and the cover body 20, and will not be described repeatedly here.

[0083] Among them, in the following embodiments, only the example where the limiting member is arranged on the outer wall of the cover body 20 and the clamping member 33 is arranged on the inner wall of the base 10 will be described.

[0084] In some embodiments, there may be two limiting members. Correspondingly, there are also two clamping members 33; the two limiting members are respectively arranged on the opposite sides of the extension member 23 in the height direction (Z1 / Z2) perpendicular to the charging case 100; the two clamping members 33 are both arranged on the connecting member 13 and respectively cooperate with the two limiting members. Thus, compared with the case where there is only one limiting member, the arrangement of the two limiting members can improve the stability of the cooperation between the limiting member and the clamping member 33, and avoid the problem that the cover body 20 tilts relative to the base 10 due to only one-sided force (one-sided being limited) during the lifting and lowering process of the cover body 20 relative to the base 10, thereby ensuring that the limiting component 30 can effectively limit the lifting and lowering stroke of the cover body 20 relative to the base 10 and improving the stability and reliability of the operation of the charging case 100.

[0085] Please refer to Figure 4 and Figure 5 , in some embodiments, the limiting member includes a first limiting member 311 and a second limiting member 313. The first limiting member 311 and the second limiting member 313 are arranged at intervals along the lifting direction of the cover body 20. The first limiting member 311 is closer to the bottom of the base 10 than the second limiting member 313, and the clamping member 33 is located between the first limiting member 311 and the second limiting member 313;

[0086] In some embodiments, the limiting members include a first limiting member 311 and a second limiting member 313. The first limiting member 311 and the second limiting member 313 are arranged at intervals along the lifting direction of the cover body 20. The first limiting member 311 is closer to the bottom of the base 10 than the second limiting member 313. The clamping member 33 is located between the first limiting member 311 and the second limiting member 313.

[0087] Specifically, in some embodiments, two protrusions are provided on the outer wall of the extension member 23. Both protrusions protrude and extend away from the center of the extension member 23 from the outer wall of the extension member 23, and the two protrusions are arranged at intervals along the lifting direction of the cover body 20. The two protrusions respectively form the first limiting member 311 and the second limiting member 313; a convex block is provided on the inner wall 131 of the connecting member 13. The convex block protrudes and extends from the inner wall 131 of the connecting member 13 towards the center of the connecting member 13. The convex block forms the clamping member 33. Wherein, when the charging case 100 is assembled, the convex block can extend into the gap between the two protrusions, that is, the clamping member 33 is located between the first limiting member 311 and the second limiting member 313. Thus, both the first limiting member 311 and the second limiting member 313 can cooperate with the clamping member 33 to limit the upward and downward strokes of the cover body 20 relative to the base 10.

[0088] In other embodiments, a groove is provided on the outer wall of the extension member 23. The groove is recessed from the outer wall of the extension member 23 towards the center of the extension member 23. The two side walls of the groove in the lifting direction of the cover body 20 respectively form the first limiting member 311 and the second limiting member 313; a convex block is provided on the inner wall 131 of the connecting member 13. The convex block protrudes and extends from the inner wall 131 of the connecting member 13 towards the center of the connecting member 13. The convex block forms the clamping member 33. Wherein, when the charging case 100 is assembled, the convex block can extend into the groove, that is, the clamping member 33 is located between the first limiting member 311 and the second limiting member 313. Thus, both the first limiting member 311 and the second limiting member 313 can cooperate with the clamping member 33 to limit the upward and downward strokes of the cover body 20 relative to the base 10.

[0089] Please refer to Figure 5 In an example, in the case where a groove is provided on the outer wall of the extension member 23 and the two side walls of the groove in the lifting direction of the cover body 20 respectively form the first limiting member 311 and the second limiting member 313, a guiding protrusion 315 extending along the lifting direction of the cover body 20 is provided in the groove, and a guiding groove 331 is provided on the convex block. The guiding protrusion 315 cooperates with the guiding groove 331 to guide and limit the lifting of the cover body 20 relative to the base 10, preventing the cover body 20 from being stuck due to deviation during the lifting and lowering process relative to the base 10, thereby improving the stability of the lifting of the cover body 20 relative to the base 10 and ensuring the normal operation of the charging case 100.

[0090] It should be noted that in some embodiments, one of the first limiting member 311 and the second limiting member 313 is an integral structure with the extension member 23, and the other of the first limiting member 311 and the second limiting member 313 is a split structure with the extension member 23. In this way, the number of components of the charging case 100 can be reduced, which is beneficial to improving the assembly efficiency of the charging case 100.

[0091] In some embodiments, when the first limiting member 311 cooperates with the clamping member 33, the limiting assembly 30 is used to limit the upward travel of the cover body 20 relative to the base 10; when the second limiting member 313 cooperates with the clamping member 33, the limiting assembly 30 is used to limit the downward travel of the cover body 20 relative to the base 10.

[0092] Specifically, in some embodiments, when the cover body 20 moves upward relative to the base 10 until the first limiting member 311 cooperates with the clamping member 33, the limiting assembly 30 can limit the upward travel of the cover body 20 relative to the base 10, that is, the cover body 20 cannot continue to move upward relative to the base 10; when the cover body 20 moves downward relative to the base 10 until the second limiting member 313 cooperates with the clamping member 33, the limiting assembly 30 can limit the downward travel of the cover body 20 relative to the base 10, that is, the cover body 20 cannot continue to move downward relative to the base 10.

[0093] More specifically, in some embodiments, when the cover body 20 is in the release position, the clamping member 33 abuts against the first limiting member 311. In this case, the cover body 20 can release the earphone 200, that is, the earphone 200 can be taken out from the earphone bin 101; when the cover body 20 is in the pressing position, the clamping member 33 abuts against the second limiting member 313. In this case, the cover body 20 can press the earphone 200, that is, the earphone 200 can be pressed in the earphone bin 101.

[0094] Please refer to Figure 4 and Figure 5 , in some embodiments, the limiting assembly 30 further includes a shock absorber 105. The shock absorber 105 is disposed on the first limiting member 311 and / or the clamping member 33. When the cover body 20 is in the release position, the shock absorber 105 is located between the first limiting member 311 and the clamping member 33.

[0095] Among them, the setting of the shock absorber 105 can prevent rigid collision between the first limiting member 311 and the clamping member 33 when they abut against each other, so as to extend the service life of the limiting assembly 30 and ensure the stability and reliability of the charging case 100 during operation. It should be noted that in some embodiments, the shock absorber 105 is made of at least one of silica gel, rubber, resin, and polyurethane.

[0096] In some embodiments, the shock absorber 105 is disposed on the side of the first limiting member 311 opposite to the engaging member 33. In other embodiments, the shock absorber 105 is disposed on the side of the engaging member 33 opposite to the first limiting member 311. In still other embodiments, there are two shock absorbers 105, and the two shock absorbers 105 are respectively disposed on the side of the first limiting member 311 opposite to the engaging member 33 and on the side of the engaging member 33 opposite to the first limiting member 311.

[0097] In some embodiments, the shock absorber 105 and the first limiting member 311 can be combined together by a detachable connection method. Among them, the detachable connection methods include but are not limited to snap connection or screw connection, etc. In other embodiments, the shock absorber 105 and the first limiting member 311 can be combined together by a non-detachable connection method. Among them, the non-detachable connection methods include but are not limited to bonding, etc. It can be understood that the connection method between the shock absorber 105 and the engaging member 33 is basically the same as the connection method between the shock absorber 105 and the first limiting member 311, and will not be described repeatedly here.

[0098] In certain embodiments, the shock absorber 105 is disposed on the second limiting member 313 and / or the engaging member 33. When the cover 20 is in the pressed position, the shock absorber 105 is located between the second limiting member 313 and the engaging member 33. Among them, the setting of the shock absorber 105 can prevent rigid collision and damage between the second limiting member 313 and the engaging member 33 when they come into contact with each other, thereby extending the service life of the limiting component 30 and ensuring the stability and reliability of the charging box 100 during operation.

[0099] In some embodiments, the shock absorber 105 is disposed on the side of the second limiting member 313 opposite to the engaging member 33. In other embodiments, the shock absorber 105 is disposed on the side of the engaging member 33 opposite to the second limiting member 313. In still other embodiments, there are two shock absorbers 105, and the two shock absorbers 105 are respectively disposed on the side of the second limiting member 313 opposite to the engaging member 33 and on the side of the engaging member 33 opposite to the second limiting member 313.

[0100] It can be understood that the connection method between the shock absorber 105 and the second limiting member 313 is basically the same as the connection method between the shock absorber 105 and the first limiting member 311, and will not be described repeatedly here.

[0101] Please refer to Figure 1 and Figure 3 , in certain embodiments, the charging box 100 further includes a fastener 106. The fastener 106 is disposed on the base 10 and / or the cover 20, and the fastener 106 is used to fix the device to be charged on the bearing surface 103.

[0102] Among them, please combine with Figure 2 The fastener 106 is a structure in the charging case 100 for fixing the earphone 200. In some embodiments of the present application, a mating member 270 is provided on the member to be charged (earphone 200), and the fastener 106 cooperates with the mating member 270 to fix the member to be charged. Specifically, when the earphone 200 is placed in the charging case 100, the fastener 106 can cooperate with the mating member 270 to fix the earphone 200, so as to prevent the earphone 200 from moving or shaking in the charging case 100, resulting in poor contact between the charging end of the earphone 200 (i.e., the second electrical connector 280) and the charging end of the charging case 100 (i.e., the first electrical connector 17), thereby improving the charging stability of the charging case 100 for the earphone 200 and ensuring the normal realization of the charging function and / or signal transmission function.

[0103] It should be noted that, in some embodiments, the cooperation modes of the fastener 106 and the mating member 270 include but are not limited to snap-fit and magnetic attraction fit, etc. In one example, when the cooperation mode of the fastener 106 and the mating member 270 is magnetic attraction fit, one of the fastener 106 and the mating member 270 is a first magnetic material, and the other is a second magnetic material or an iron component that attracts the first magnetic material.

[0104] In some embodiments, the fastener 106 is a magnetic member, and the mating member 270 is a magnetic attraction member, and the magnetic poles of the magnetic member and the magnetic attraction member are opposite. This can ensure the stability of the cooperation between the magnetic member and the magnetic attraction member, thereby preventing the earphone 200 from moving or shaking in the charging case 100, resulting in poor contact between the second electrical connector 280 and the first electrical connector 17, thereby improving the charging stability of the charging case 100 for the earphone 200. Exemplarily, both the magnetic member and the magnetic attraction member can be magnets. When the earphone 200 is disposed in the profiling groove, the S pole of the magnetic member is opposite to the N pole of the magnetic attraction member.

[0105] In some embodiments, the cover body 20 and / or the base 10 is provided with a profiling groove 1019 for limiting the earphone 200, and the profiling groove 1019 matches the outer contour of the earphone 200. The fastener 106 is disposed on the base 10 and / or the cover body 20, and the fastener 106 is used to fix the earphone 200 in the profiling groove 1019. It should be noted that, in some embodiments, the bearing surface 103 can be the bottom wall of the profiling groove 1019.

[0106] Among them, the profiling groove 1019 is a groove or cavity manufactured according to a specific shape (such as the outer contour of the earphone 200). In some embodiments of the present application, the profiling groove 1019 matches the outer contour of the earphone 200, that is, the shape, size, and contour of the profiling groove 1019 are exactly the same or almost exactly the same as the shape, size, and contour of the earphone 200. The setting of the profiling groove 1019 can, on the one hand, facilitate the installation and positioning of the earphone 200 on the charging case 100; on the other hand, it can limit the installation of the earphone 200 on the charging case 100 and improve the stability of the earphone 200 stored in the charging case 100.

[0107] In some embodiments, when the earphone 200 includes a battery compartment 220, the profiling groove 1019 is used to limit the battery compartment 220 and matches the outer contour of the battery compartment 220, that is, the shape, size, and contour of the profiling groove 1019 are exactly the same or almost exactly the same as the shape, size, and contour of the battery compartment 220, so as to improve the stability of the battery compartment 220 stored in the charging case 100. It can be understood that the second electrical connector 280 is provided in the battery compartment 220 and is electrically connected to the battery in the battery compartment 220.

[0108] In some embodiments, the profiling groove 1019 is provided on the base 10. In other embodiments, the profiling groove 1019 is provided on the cover 20. In still other embodiments, the profiling groove 1019 is provided on both the base 10 and the cover 20. Among them, the profiling groove 1019 on the base 10 and the profiling groove 1019 on the cover 20 both match the outer contour of the earphone 200. It can be understood that the orthographic projection of the profiling groove 1019 on the cover 20 on the base 10 at least partially overlaps with the profiling groove 1019 on the base 10. The shape, size, and contour of the profiling groove 1019 on the base 10 and the profiling groove 1019 on the cover 20 may be the same or different.

[0109] Please refer to Figure 6 , in some embodiments, the cover 20 further includes a first protrusion 25, and the first protrusion 25 extends from the main body 21 toward the base 10, and the first protrusion 25 participates in forming the earphone compartment 101.

[0110] Specifically, in some embodiments, when the cover 20 presses the earphone 200, the first protrusion 25 can limit at least one side of the earphone 200, thereby improving the pressing effect of the cover 20 on the earphone 200, reducing the possibility of the earphone 200 detaching from the charging case 100, and ensuring the stability of the charging case 100 for charging and accommodating the earphone 200.

[0111] More specifically, in some embodiments, when the cover 20 includes the first protrusion 25, the first protrusion 25 and the extension 23 are respectively disposed on opposite side edges of the main body 21. Thus, when the cover 20 presses the earphone 200, the first protrusion 25 and the extension 23 can jointly limit the position of the earphone 200, reducing the possibility of the earphone 200 detaching from the charging case 100.

[0112] In some embodiments, the base 10 further includes a second protrusion 15 that extends from the seat body 11 toward the cover 20, and the second protrusion 15 participates in forming the earphone compartment 101.

[0113] Specifically, in some embodiments, when the cover 20 presses the earphone 200, the second protrusion 15 can limit at least one side of the earphone 200, thereby reducing the possibility of the earphone 200 detaching from the charging case 100 and ensuring the stability of the charging case 100 for charging and accommodating the earphone 200.

[0114] More specifically, in some embodiments, when the base 10 includes the second protrusion 15, the second protrusion 15 and the connecting member 13 are respectively disposed on opposite side edges of the seat body 11. Thus, when the cover 20 presses the earphone 200, the second protrusion 15 and the connecting member 13 can jointly limit the position of the earphone 200, reducing the possibility of the earphone 200 detaching from the charging case 100.

[0115] In some embodiments, a buffer member 107 is provided on the side of the cover 20 facing the base 10. When the device to be charged is placed on the bearing surface 103, the buffer member 107 is located between the device to be charged and the cover 20.

[0116] Wherein, the provision of the buffer member 107 can prevent rigid collision between the cover 20 and the earphone 200 when the cover 20 presses the earphone 200, resulting in damage. Thus, the service life of the earphone 200 and the charging case 100 can be extended, ensuring the normal operation of the earphone 200 and the charging case 100. It should be noted that in some embodiments, the material of the buffer member 107 includes but is not limited to silicone, rubber, resin, etc.

[0117] Specifically, in some embodiments, when the earphone 200 is placed on the bearing surface 103, the buffer member 107 is located between the earphone 200 and the cover 20, that is, the buffer member 107 is provided on the cover 20 and is located in the earphone compartment 101. In one example, the shape, size, and contour of the buffer member 107 match those of the earphone 200. In another example, when the cover 20 presses the earphone 200, the buffer member 107 can undergo elastic deformation, and the shape, size, and contour of the deformed buffer member 107 still match those of the earphone 200.

[0118] In some embodiments, a buffer member 107 is provided on the side of the base 10 facing the cover 20. When the device to be charged is carried on the carrying surface 103, the buffer member 107 is located between the device to be charged and the base 10.

[0119] Among them, the setting of the buffer member 107 can prevent rigid collision between the base 10 and the earphone 200 when the earphone 200 is put into the earphone compartment 101, so as to extend the service life of the earphone 200 and the charging case 100 and ensure the normal operation of the earphone 200 and the charging case 100. It should be noted that in some embodiments, the material of the buffer member 107 includes but is not limited to silicone, rubber, resin, etc.

[0120] Specifically, in some embodiments, when the earphone 200 is carried on the carrying surface 103, the buffer member 107 is located between the earphone 200 and the base 10, that is, the buffer member 107 is provided on the base 10 and is located in the earphone compartment 101. In one example, the shape, size and contour of the buffer member 107 match the shape, size and contour of the earphone 200. In another example, when the cover 20 presses the earphone 200, the buffer member 107 can undergo elastic deformation, and the shape, size and contour of the deformed buffer member 107 still match the shape, size and contour of the earphone 200.

[0121] In the related art, the charging case includes metal posts, and the metal posts can provide guidance for the movement of the cover relative to the base. However, limited by the size of the metal posts, the cover is prone to looseness or shaking during the movement relative to the base, affecting the stability of the opening and closing of the charging case.

[0122] Therefore, please refer to Figure 3 and Figure 7 , in some embodiments of the present application, the lifting assembly 40 includes a first guiding member 41 and a second guiding member 43. The first guiding member 41 is provided on the side wall 231 of the extension member 23 of the cover 20, and the second guiding member 43 is provided on the inner wall 131 of the connecting member 13 of the base 10. The first guiding member 41 and the second guiding member 43 cooperate to limit the movement of the cover 20 relative to the base 10 in the horizontal direction, and the horizontal direction is perpendicular to the lifting direction of the cover 20. Thus, the setting of the first guiding member 41 and the second guiding member 43 can, on the one hand, limit the movement of the cover 20 relative to the base 10 in the horizontal direction, that is, prevent the cover 20 from moving relative to the base 10 in the horizontal direction. Therefore, compared with the charging case 100 including metal posts in the related art, the setting of the first guiding member 41 and the second guiding member 43 can prevent looseness or shaking during the movement of the cover 20 relative to the base 10, thereby improving the stability of the opening and closing of the charging case 100; on the other hand, it can provide guidance for the lifting movement of the cover 20 relative to the base 10, thereby also improving the stability of the opening and closing of the charging case 100.

[0123] In addition, compared with the metal posts in the related art that provide guidance for the movement of the cover body 20 relative to the base 10, the production cost of the charging case 100 in this embodiment is lower, which is beneficial to improving the product competitiveness.

[0124] In some embodiments, one of the first guiding member 41 and the second guiding member 43 is a protrusion, and the other is a groove. In one example, the first guiding member 41 is a protrusion and the second guiding member 43 is a groove. In another example, the first guiding member 41 is a groove and the second guiding member 43 is a protrusion.

[0125] Wherein, when the first guiding member 41 is a groove and the second guiding member 43 is a protrusion, the first guiding member 41 can be recessed from the side wall 231 of the extension member 23 towards the center of the extension member 23; the second guiding member 43 can protrude from the inner wall 131 of the connecting member 13 towards the center of the connecting member 13. When the extension member 23 extends into the connecting member 13, the second guiding member 43 can extend into the first guiding member 41 to guide the lifting of the extension member 23 relative to the connecting member 13.

[0126] In other embodiments, one of the first guiding member 41 and the second guiding member 43 is a slider, and the other is a slide rail. In one example, the first guiding member 41 is a slider and the second guiding member 43 is a slide rail. In another example, the first guiding member 41 is a slide rail and the second guiding member 43 is a slider.

[0127] In certain embodiments, the first guiding member 41 and the extension member 23 are of an integral structure. That is, the first guiding member 41 and the extension member 23 can be formed into a whole by an integral molding method, so as to improve the connection stability between the first guiding member 41 and the extension member 23. Moreover, compared with the charging case 100 in the related art including metal posts, the integral structure of the first guiding member 41 and the extension member 23 can also reduce the assembly steps of the charging case 100, thereby improving the assembly efficiency of the charging case 100.

[0128] It can be understood that in other embodiments, the first guiding member 41 and the extension member 23 can be of a split structure, that is, the first guiding member 41 and the extension member 23 are two different structures. The first guiding member 41 and the extension member 23 can be combined together by a detachable connection method or a non-detachable connection method. Among them, the detachable connection methods include but are not limited to snap connection or bolt connection, etc.; the non-detachable connection methods include but are not limited to bonding or welding, etc.

[0129] In some embodiments, the second guide member 43 and the connecting member 13 are of an integral structure. That is to say, the second guide member 43 and the connecting member 13 can be integrally formed in one piece, which can improve the connection stability between the second guide member 43 and the connecting member 13. Moreover, compared with the charging case 100 including a metal post in the related art, the integral structure of the second guide member 43 and the connecting member 13 can also reduce the assembly steps of the charging case 100, thereby improving the assembly efficiency of the charging case 100.

[0130] It can be understood that in other embodiments, the second guide member 43 and the connecting member 13 can be of a split structure, that is, the second guide member 43 and the connecting member 13 are two different structures. The second guide member 43 and the connecting member 13 can be combined together by a detachable connection method or a non-detachable connection method. Among them, the detachable connection methods include but are not limited to snap connection or bolt connection, etc.; the non-detachable connection methods include but are not limited to bonding or welding, etc.

[0131] 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 that are connected in sequence, and the first guide member 41 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.

[0132] Exemplarily, the first guide member 41 can be disposed on opposite sides of the extension member 23. For example, the first guide member 41 can be disposed on the first side 2311 and the third side 2315 of the extension member; or, the first guide member 41 can be disposed on the second side 2313 and the fourth side 2317 of the extension member, which can ensure the balance during the movement of the cover body 20 relative to the base 10, thereby improving the opening and closing stability of the charging case 100. Among them, when the first guide member 41 is a groove and the second guide member 43 is a protrusion, the quantitative relationship between the first guide member 41 and the second guide member 43 can be one-to-one or one-to-many, that is, one first guide member 41 corresponds to one second guide member 43; or, one first guide member 41 corresponds to multiple second guide members 43.

[0133] In some embodiments, at least one first guiding member 41 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, on the same side of the extension member 23 (such as the first side 2311, the second side 2313, the third side 2315, or the fourth side 2317 of the extension member), there is at least one first guiding member 41, so as to prevent the extension member 23 from deflecting or shaking in the connecting member 13 during the movement of the cover body 20 relative to the base 10, and further improve the stability of the cover body 20 when moving relative to the base 10.

[0134] In the related art, the base 10 and the cover body 20 are usually combined by magnetic attraction. However, the magnetic attraction is easily affected by the outside world. For example, when the magnetic attraction decreases due to the influence of the outside world, the cover body 20 may be accidentally opened under slight external force or vibration, affecting the stability of the storage of the earphone 200; for another example, when the magnetic attraction increases due to the influence of the outside world, the cover body 20 may be difficult to open, affecting the taking and placing of the earphone 200.

[0135] Please refer to Figure 3 , Figure 6 and Figure 7 , in some embodiments of the present application, the charging case 100 further includes a button structure 60. The button structure 60 includes a engaging member 61, a cooperating member 63, and a reset member 65. The engaging member 61 reciprocates between a locking position and a first unlocking position along a first direction (Z1 / Z2), and the engaging member 61 is used to connect one of the base 10 and the cover body 20. The cooperating member 63 reciprocates between a locking position and a second unlocking position along a second direction (X1 / X2), and the cooperating member 63 is used to connect the other of the base 10 and the cover body 20. The reset member 65 is connected between the cooperating member 63 and the base 10 or the cover body 20, and the reset member 65 is used to keep the cooperating member 63 in the locking position. Wherein, the first direction (Z1 / Z2) and the second direction (X1 / X2) intersect, and when the engaging member 61 and the cooperating member 63 are in the locking position, the engaging member 61 and the cooperating member 63 are engaged and cooperated. It should be noted that, in some embodiments, the first direction (Z1 / Z2) is the same as the height direction (Z1 / Z2) of the charging case 100.

[0136] Wherein, in some embodiments, the engaging member 61 is connected to the cover body 20, the cooperating member 63 is connected to the base 10, and the reset member 65 is connected between the cooperating member 63 and the base 10. In other embodiments, the engaging member 61 is connected to the base 10, the cooperating member 63 is connected to the cover body 20, and the reset member 65 is connected between the cooperating member 63 and the cover body 20. In the embodiments of the present application, only the example where the engaging member 61 is connected to the cover body 20, the cooperating member 63 is connected to the base 10, and the reset member 65 is connected between the cooperating member 63 and the base 10 is taken for illustration.

[0137] Specifically, in some embodiments, when the engaging member 61 and the mating member 63 are in the locked position, the engaging member 61 and the mating member 63 are snap-fitted together. In this case, the cover 20 can press the earphone 200. In other words, when the cover 20 is in the pressing position, the engaging member 61 and the mating member 63 are in the locked position; when the engaging member 61 is in the first unlocking position and the mating member 63 is in the second unlocking position, the engaging member 61 and the mating member 63 are disengaged from the snap-fitting. In this case, the cover 20 can release the earphone 200. In other words, when the cover 20 is in the releasing position, the engaging member 61 is in the first unlocking position and the mating member 63 is in the second unlocking position. Wherein, the first direction (Z1 / Z2) is the lifting direction of the cover 20.

[0138] It can be understood that in some embodiments, the reciprocating movement of the mating member 63 between the locked position and the second unlocking position along the second direction (X1 / X2) requires manual intervention, that is, manually making the mating member 63 switch between the locked position and the second unlocking position along the second direction (X1 / X2); or, manually using a tool to make the mating member 63 switch between the locked position and the second unlocking position along the second direction (X1 / X2). Exemplarily, when a user applies a force to the mating member 63, the mating member 63 can move from the locked position to the second unlocking position along the second direction (X1 / X2) relative to the base 10; when the user does not apply a force to the mating member 63, the mating member 63 can move from the second unlocking position to the locked position along the second direction (X1 / X2) under the action of the reset member 65. Wherein, when the mating member 63 moves along the second direction (X1 / X2), the base 10 does not move along the second direction (X1 / X2) with the mating member 63. In other words, the mating member 63 can move relative to the base 10 along the second direction (X1 / X2).

[0139] The reciprocating movement of the engaging member 61 between the locked position and the first unlocking position along the first direction (Z1 / Z2) requires manual intervention, that is, manually making the engaging member 61 switch between the locked position and the first unlocking position along the first direction (Z1 / Z2); or, manually using a tool to make the engaging member 61 switch between the locked position and the first unlocking position along the first direction (Z1 / Z2). Exemplarily, when a user applies a force to the engaging member 61, the engaging member 61 can move from the first unlocking position to the locked position along the first direction (Z1 / Z2); when the user does not apply a force to the engaging member 61 and the mating member 63 is in the second unlocking position, the engaging member 61 can move from the locked position to the first unlocking position along the first direction (Z1 / Z2). Wherein, when the engaging member 61 moves along the first direction (Z1 / Z2), the cover 20 moves along the first direction (Z1 / Z2) with the engaging member 61.

[0140] 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) can be the height direction (Z1 / Z2) of the charging case 100. In other examples, as long as the first direction (Z1 / Z2) and the second direction (X1 / X2) intersect, the included angle between them can be any angle between (0° and 180°), such as the included angle between them can be 15°, 30°, 45°, 60°, 75°, 100°, 115°, 120°, or 135°, etc. In the embodiments of the present application, only the case where the first direction (Z1 / Z2) and the second direction (X1 / X2) are perpendicular is taken as an example for illustration.

[0141] In summary, the engaging member 61 reciprocates between the locking position and the first unlocking position along the first direction (Z1 / Z2), the engaging member 61 is connected to one of the base 10 and the cover 20, the cooperating member 63 reciprocates between the locking position and the second unlocking position along the second direction (X1 / X2), the cooperating member 63 is connected to the other of the base 10 and the cover 20, and when the engaging member 61 and the cooperating member 63 are in the locking position, the engaging member 61 and the cooperating member 63 are engaged and cooperate with each other. Thus, compared with the charging case 100 in the related art, the arrangement of the button structure 60 can prevent the relative movement between the cover 20 and the base 10 from being unstable due to the change of the magnetic attraction force, thereby improving the stability of the charging case 100.

[0142] Please refer to Figure 3 、 Figure 6 and Figure 7 , in some embodiments, the button structure 60 further includes an elastic member 67. The elastic member 67 is connected between the base 10 and the cover 20 and extends along the first direction (Z1 / Z2). The reset member 65 is connected between the cooperating member 63 and the base 10 and extends along the second direction (X1 / X2). When the cover 20 is in the pressed position, the elastic member 67 has a first length and the reset member 65 is in a first state; when the cover 20 is in the released position, the elastic member 67 has a second length and the reset member 65 is in a second state, and the second length is greater than the first length.

[0143] Specifically, in some embodiments, when the cover 20 switches from the pressing position to the releasing position, the size of the earphone compartment 101 in the height direction (Z1 / Z2) of the charging case 100 increases, and the second length of the elastic member 67 when the cover 20 is in the releasing position is greater than the first length of the elastic member 67 when the cover 20 is in the pressing position. Therefore, when the cover 20 is in the pressing position, the elastic member 67 is in a compressed state; when the cover 20 is in the releasing position, the elastic member 67 is in a normal state (a state where it is neither stretched nor compressed) or a compressed state (at this time, the compression amount of the elastic member 67 is less than the compression amount of the elastic member 67 when the cover 20 is in the pressing position). Thus, during the process of the cover 20 switching from the pressing position to the releasing position, the elastic member 67 can provide an elastic force for the cover 20, thereby ensuring that the cover 20 can smoothly rise relative to the base 10.

[0144] In some embodiments, during the process of the cover 20 switching from the pressing position to the releasing position, the reset member 65 sequentially switches between the first state, the second state, and the first state. During the process of the cover 20 switching from the releasing position to the pressing position, the reset member 65 sequentially switches between the first state, the second state, and the first state, and the length of the reset member 65 in the first state is different from the length of the reset member 65 in the second state.

[0145] Specifically, in some embodiments, when the reset member 65 is in the first state, both the engaging member 61 and the cooperating member 63 are located at the locking positions; when the reset member 65 is in the second state, the engaging member 61 is located at the first unlocking position, and the cooperating member 63 is located at the second unlocking position.

[0146] Among them, when the cover 20 switches from the pressing position to the releasing position, the reset member 65 sequentially switches between the first state, the second state, and the first state, that is, the cooperating member 63 sequentially switches between the locking position, the second unlocking position, and the locking position. When the cooperating member 63 moves from the locking position to the second unlocking position, the engaging and cooperating relationship between the cooperating member 63 and the engaging member 61 is released, and the engaging member 61 moves from the locking position to the first unlocking position. It can be understood that the length of the reset member 65 in the first state is different from the length of the reset member 65 in the second state. In this way, the reset member 65 can generate a reset force on the cooperating member 63, and the reset force is used to keep the cooperating member 63 at the locking position.

[0147] Further, in some embodiments, when the cover body 20 is in the pressing position and the fitting member 63 is subjected to a first acting force, the fitting member 63 can move in the positive direction X1 of the second direction (X1 / X2), the reset member 65 switches from the first state to the second state, and the elastic member 67 elongates and pushes the cover body 20 to move in the ascending direction of the cover body 20; when the first acting force disappears, the reset member 65 switches from the second state to the first state, the fitting member 63 moves in the reverse direction X2 of the second direction (X1 / X2), and is located below the engaging member 61.

[0148] Specifically, in some embodiments, when the fitting member 63 is subjected to a first acting force and the fitting member 63 moves in the positive direction X1 of the second direction (X1 / X2), the reset member 65 generates a reset force, and the fitting member 63 moves from the locking position to the second unlocking position to release the clamping fit between the fitting member 63 and the engaging member 61, and the elastic force of the elastic member 67 can push the cover body 20 to move in the ascending direction of the cover body 20; when the first acting force disappears, the reset force of the reset member 65 can cause the fitting member 63 to move in the reverse direction X2 of the second direction (X1 / X2), that is, the reset force can cause the fitting member 63 to move from the second unlocking position to the locking position. In this case, the fitting member 63 is located below the engaging member 61. Thus, when the fitting member 63 is subjected to a first acting force, the cover body 20 can be switched from the pressing position to the release position.

[0149] In some embodiments, when the cover body 20 is in the release position and the cover body 20 is subjected to a second acting force, the elastic member 67 is compressed, the cover body 20 moves in the descending direction of the cover body 20, the engaging member 61 pushes the fitting member 63 to move in the positive direction X1 of the second direction (X1 / X2), and the reset member 65 switches from the first state to the second state; when the engaging member 61 is in the locking position, the fitting member 63 moves in the reverse direction X2 of the second direction (X1 / X2), and the reset member 65 switches from the second state to the first state.

[0150] Specifically, in some embodiments, when the cover body 20 is subjected to a second acting force and the cover body 20 moves along the descending direction of the cover body 20 (the direction from the cover body 20 to the base 10), the engaging member 61 generates a thrust force on the mating member 63 to push the mating member 63 to move forward in the positive direction X1 of the second direction (X1 / X2). At this time, the restoring member 65 generates a restoring force, and the mating member 63 moves from the locking position to the second unlocking position; when the engaging member 61 moves along the descending direction of the cover body 20 to the locking position, the engaging member 61 does not generate a thrust force on the mating member 63, and the restoring force of the restoring member 65 can cause the mating member 63 to move in the reverse direction X2 of the second direction (X1 / X2), that is, the restoring force can cause the mating member 63 to move from the second unlocking position to the locking position. In this case, the engaging member 61 and the mating member 63 are snap-fitted. Thus, when the cover body 20 is subjected to a second acting force, the cover body 20 can be switched from the release position to the pressing position.

[0151] Please refer to Figures 3 to 7 , in some embodiments, the first acting force received by the mating member 63 is a pressure, the length of the restoring member 65 in the first state is greater than the length of the restoring member 65 in the second state, the positive direction X1 of the second direction (X1 / X2) is the direction towards the inside of the base 10, and the reverse direction X2 of the second direction (X1 / X2) is the direction towards the outside of the base 10.

[0152] Specifically, please combine Figure 6 and Figure 7 , in some embodiments, when the engaging member 61 and the mating member 63 are snap-fitted, the restoring member 65 is located on the side of the mating member 63 opposite to the engaging member 61. At this time, the restoring member 65 can be a compression spring. When the restoring member 65 is in the first state, the mating member 63 is located at the locking position, and the restoring member 65 is in a normal state (a state not being stretched or compressed) or in a first compressed state; when the restoring member 65 is in the second state, the mating member 63 is located at the second unlocking position, and the restoring member 65 is in a second compressed state. Among them, the length of the restoring member 65 in the first compressed state is greater than the length of the restoring member 65 in the second compressed state.

[0153] Please refer to Figure 3 and Figure 9 , in some embodiments, the first acting force received by the mating member 63 is a tensile force, the length of the restoring member 65 in the first state is less than the length of the restoring member 65 in the second state, the positive direction X1 of the second direction (X1 / X2) is the direction towards the outside of the base 10, and the reverse direction X2 of the second direction (X1 / X2) is the direction towards the inside of the base 10.

[0154] Specifically, please combine Figure 9, in some embodiments, when the engaging member 61 and the mating member 63 are engaged, the reset member 65 is located on the side of the mating member 63 opposite to the engaging member 61. At this time, the reset member 65 can be a tension spring. When the reset member 65 is in the first state, the mating member 63 is located at the locking position, and the reset member 65 is in the normal state (the state of not being stretched or compressed) or in the first stretched state; when the reset member 65 is in the second state, the mating member 63 is located at the second unlocking position, and the reset member 65 is in the second stretched state. Among them, the length of the reset member 65 in the first stretched state is less than the length of the reset member 65 in the second stretched state.

[0155] Please refer to Figures 3 to 7 , and in combination with Figure 8 or Figure 9 , in some embodiments, the mating member 63 includes a mating body 631 and a hook portion 633, and the engaging member 61 includes an engaging body 611 and an engaging portion 613. The hook portion 633 cooperates with the engaging portion 613 to enable the mating member 63 to be engaged with the engaging member 61.

[0156] Specifically, in some embodiments, when both the engaging member 61 and the mating member 63 are located at the locking position, the hook portion 633 cooperates with the engaging portion 613; when the engaging member 61 is located at the first unlocking position and the mating member 63 is located at the second unlocking position, the hook portion 633 is disengaged from the engaging portion 613.

[0157] In some embodiments, the mating body 631 and the hook portion 633 are an integral structure, that is, the mating body 631 and the hook portion 633 can be formed as a whole by an integral molding method. In this way, the connection stability between the mating body 631 and the hook portion 633 can be improved, and the hook portion 633 can be prevented from falling off the mating body 631 when the hook portion 633 cooperates with the engaging portion 613, so as to ensure the stability and reliability of the operation of the button structure 60.

[0158] In other embodiments, the mating body 631 and the hook portion 633 are a split structure, that is, the mating body 631 and the hook portion 633 are two different structures. In one example, the mating body 631 and the hook portion 633 can be combined together by a detachable connection method, and the detachable connection method includes but is not limited to snap connection or bolt connection, etc. In another example, the mating body 631 and the hook portion 633 can be combined together by a non-detachable connection method, and the non-detachable connection method includes but is not limited to bonding or welding, etc. It can be understood that the connection method between the engaging body 611 and the engaging portion 613 is basically the same as the connection method between the mating body 631 and the hook portion 633, and will not be elaborated here.

[0159] Further, in some embodiments, a first inclined surface 6131 is provided on the engaging portion 613, and a second inclined surface 6331 is provided on the engaging hook portion 633. During the process of the cover body 20 switching from the release position to the pressing position, the first inclined surface 6131 abuts against the second inclined surface 6331.

[0160] If the first inclined surface 6131 is not provided on the engaging portion 613 and the second inclined surface 6331 is not provided on the engaging hook portion 633, then when the engaging portion 613 moves along the descending direction of the cover body 20 so that the engaging portion 613 abuts against the engaging hook portion 633, the engaging portion 613 can only generate a thrust force on the engaging hook portion 633 along the first direction (Z1 / Z2) (i.e., the lifting direction of the charging box 100), and this thrust force cannot push the engaging hook portion 633 to move along the second direction (X1 / X2). Therefore, the provision of the first inclined surface 6131 and the second inclined surface 6331 enables the engaging portion 613 to generate a thrust force on the engaging hook portion 633 when the first inclined surface 6131 abuts against the second inclined surface 6331, and the component force of this thrust force in the second direction (X1 / X2) can push the engaging hook portion 633 to move along the second direction (X1 / X2).

[0161] Specifically, in some embodiments, the angle between the first inclined surface 6131 and the positive direction X1 of the second direction (X1 / X2) is a first acute angle, and the angle between the second inclined surface 6331 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 magnitudes of the first acute angle and the second acute angle may be the same or different.

[0162] In some embodiments, a first flat surface 6133 is provided on the engaging portion 613, and a second flat surface 6333 is provided on the engaging hook portion 633. When the cover body 20 is in the pressing position, the first flat surface 6133 abuts against the second flat surface 6333. Among them, both the first flat surface 6133 and the second flat surface 6333 can be perpendicular to the first direction (Z1 / Z2). Therefore, the abutment of the first flat surface 6133 and the second flat surface 6333 can achieve the snap-fit between the engaging portion 613 and the engaging portion 63, thereby restricting the lifting of the cover body 20 relative to the base 10.

[0163] Please refer to Figure 6 and Figure 7, in some embodiments, a first guide member 108 is provided on the base 10 or the cover 20. The first guide member 108 extends along a first direction (Z1 / Z2), and cooperates with the elastic member 67 and is used to guide the expansion and contraction of the elastic member 67. Among them, the first guide member 108 can provide limitation and guidance for the deformation of the elastic member 67, reduce or even avoid the deformation of the elastic member 67 in a direction other than the first direction (Z1 / Z2), and ensure that the elastic member 67 can provide an effective elastic force to the cover 20, so that the cover 20 can be switched from the pressed position to the released position. It should be noted that the quantity relationship between the first guide member 108 and the elastic member 67 is one-to-one correspondence, that is, one first guide member 108 corresponds to one elastic member 67.

[0164] In some embodiments, the first guide member 108 is a cylinder, and the elastic member 67 is sleeved on the side wall of the cylinder.

[0165] Specifically, in one example, the outer contour of the side wall of the cylinder is a continuous and uninterrupted closed ring. Exemplarily, the cylinder can be a cylindrical shape. At this time, the outer contour of the side wall of the cylinder is a circle. In another example, the outer contour of the side wall of the cylinder is a non-closed ring with at least one break. Thus, when the elastic member 67 is sleeved on the side wall of the cylinder, the contact area between the elastic member 67 and the side wall of the cylinder is small, so that the friction between the elastic member 67 and the cylinder can be reduced, and the stability of the elastic member 67 expanding and contracting along the first direction (Z1 / Z2) can be ensured. Exemplarily, at least one groove is provided on the cylinder, and the groove is recessed from the outside of the side wall of the cylinder towards the center of the cylinder.

[0166] In some other embodiments, the first guide member 108 is a cylinder, and an accommodation space is provided in the cylinder, and the elastic member 67 is accommodated in the accommodation space.

[0167] Specifically, in one example, the inner contour of the side wall of the cylinder is a continuous and uninterrupted closed ring. Exemplarily, the accommodation space can be a cylindrical shape. At this time, the inner contour of the side wall of the cylinder is a circle. In another example, the inner contour of the side wall of the cylinder is a non-closed ring with at least one break. Thus, when the elastic member 67 is accommodated in the accommodation space, the contact area between the elastic member 67 and the side wall of the cylinder is small, so that the friction between the elastic member 67 and the cylinder can be reduced, and the stability of the elastic member 67 expanding and contracting along the first direction (Z1 / Z2) can be ensured.

[0168] In some embodiments, a second guiding member 109 is provided on the base 10 or the fitting 63. The second guiding member 109 extends along a second direction (X1 / X2). The second guiding member 109 cooperates with the reset member 65 and is used to guide the telescopic movement of the reset member 65. Among them, the second guiding member 109 can provide limitation and guidance for the deformation of the reset member 65, reduce or even avoid the deformation of the reset member 65 in a direction other than the second direction (X1 / X2), and ensure that the reset member 65 can provide an effective reset force for the fitting 63 so that the fitting 63 is maintained at the locked position. It should be noted that the quantity relationship between the second guiding member 109 and the reset member 65 is one-to-one correspondence, that is, one second guiding member 109 corresponds to one reset member 65.

[0169] In some embodiments, the second guiding member 109 is a cylinder, and the reset member 65 is sleeved on the side wall of the cylinder.

[0170] Specifically, in one example, the outer contour of the side wall of the cylinder is a continuous and unbroken closed ring. Exemplarily, the cylinder can be a cylindrical shape. At this time, the outer contour of the side wall of the cylinder is a circle. In another example, the outer contour of the side wall of the cylinder is a non-closed ring with at least one break. Thus, in the case where the reset member 65 is sleeved on the side wall of the cylinder, the contact area between the reset member 65 and the side wall of the cylinder is small, thereby reducing the friction between the reset member 65 and the cylinder and ensuring the stability of the telescopic movement of the reset member 65 along the second direction (X1 / X2).

[0171] In other embodiments, the second guiding member 109 is a cylinder, and an accommodating space is provided in the cylinder. The reset member 65 is accommodated in the accommodating space.

[0172] Specifically, in one example, the inner contour of the side wall of the cylinder is a continuous and unbroken closed ring. Exemplarily, the accommodating space can be a cylindrical shape. At this time, the inner contour of the side wall of the cylinder is a circle. In another example, the inner contour of the side wall of the cylinder is a non-closed ring with at least one break. Thus, in the case where the elastic member 67 is accommodated in the accommodating space, the contact area between the elastic member 67 and the side wall of the cylinder is small, thereby reducing the friction between the elastic member 67 and the cylinder and ensuring the stability of the telescopic movement of the elastic member 67 along the first direction (Z1 / Z2).

[0173] Please continue to refer to Figure 6 and Figure 7 , in some embodiments, a blocking member 51 and a supporting member 53 are provided in the base 10. One end of the reset member 65 is connected to the blocking member 51, and the other end is connected to the fitting 63. The fitting 63 is carried on the supporting member 53 and can move along the second direction (X1 / X2) on the supporting member 53.

[0174] Specifically, in some embodiments, the blocking member 51 is disposed on the bottom wall of the base 10, and the blocking member 51 includes a blocking body 511 and two connecting portions 513 located at opposite ends of the blocking body 511. The connecting portions 513 are connected to the inner side of the side wall of the base 10. In the second direction (X1 / X2), the blocking body 511 is spaced apart from the side wall of the base 10. One end of the reset member 65 is connected to the blocking body 511, and the other end is connected to the cooperating member 63. Thus, when the cooperating member 63 moves from the locked position to the second unlocking position in the second direction (X1 / X2), the reset member 65 can generate a reset force, and this reset force can reset the cooperating member 63 from the second unlocking position to the locked position.

[0175] Wherein, along the height direction (Z1 / Z2) of the charging case 100 (i.e., the first direction (Z1 / Z2)), the reset member 65 is located below the cooperating member 63, and the support member 53 can support the cooperating member 63. Thus, the support member 53 can guide the movement of the cooperating member 63 and prevent the cooperating member 63 from shifting during movement. For example, when the cooperating member 63 moves in the second direction (X1 / X2), it does not shift downward, thereby ensuring the stability of the movement of the cooperating member 63 and improving the stability and reliability of the operation of the button structure 60.

[0176] Further, in some embodiments, the cooperating member 63 includes a contact surface opposite to the support member 53 (the side of the cooperating member 63 opposite to the support member 53), and the contact area between the support member 53 and the contact surface is smaller than the area of the contact surface. Thus, compared with the case where the contact area between the support member 53 and the contact surface is equal to the area of the contact surface, the frictional force between the cooperating member 63 and the support member 53 is smaller, thereby facilitating the movement of the cooperating member 63 relative to the support member 53 in the second direction (X1 / X2).

[0177] As can be seen from the above, when the cooperating member 63 is subjected to a first acting force, the cover body 20 can be switched from the pressed position to the released position. In other words, in order to switch the cover body 20 from the pressed position to the released position, a first acting force needs to be applied to the cooperating member 63. However, since the cooperating member 63 is disposed inside the base 10, it may be difficult for the user to reach inside the base 10 to apply a force to the cooperating member 63, which will affect the normal use of the charging case 100.

[0178] In some embodiments of the present application, the button structure 60 further includes a pressing member 69. The pressing member 69 is connected to the cooperating member 63 and can move along the second direction (X1 / X2) together with the cooperating member 63. The pressing member 69 is exposed from the side wall of the base 10. Thus, the user can apply a first acting force to the cooperating member 63 without reaching inside the base 10. That is, the user can apply a first acting force to the cooperating member 63 through the pressing member 69, thereby ensuring the normal use of the charging case 100.

[0179] In some embodiments, the pressing member 69 and the mating member 63 are of an integral structure, that is, the pressing member 69 and the mating member 63 can be formed as a whole by integral molding. In this way, the connection stability between the pressing member 69 and the mating member 63 can be improved, and it can be prevented that the pressing member 69 falls off from the mating member 63 when the user presses.

[0180] In other embodiments, the pressing member 69 and the mating member 63 are of a split structure, that is, the pressing member 69 and the mating member 63 are two different structures. In one example, the pressing member 69 and the mating member 63 can be combined together by a detachable connection method, and the detachable connection methods include but are not limited to snap connection or bolt connection, etc. In another example, the pressing member 69 and the mating member 63 can be combined together by a non-detachable connection method, and the non-detachable connection methods include but are not limited to bonding or welding, etc.

[0181] Please refer to Figure 7 、 Figure 12 and Figure 14 In some embodiments of the present application, the base 10 is provided with at least one through hole 104. The charging case 100 further includes a sealing assembly 50, and the sealing assembly 50 is disposed on the base 10 and is at least used to block external fluid from entering the inside of the base 10 through the through hole 104. Thereby, it can be prevented that the external fluid damages the internal components of the base 10, enhancing waterproof performance, and thus the normal operation of the charging case 100 can be ensured.

[0182] It should be noted that in some embodiments of the present application, the at least one through hole 104 includes the first through hole 1041, the second through hole 1043, the third through hole 1045, the fourth through hole 1047 and the fifth through hole 1049 described in the following embodiments; the sealing assembly 50 includes the blocking member 51 described in the above embodiments, and the sealing assembly 50 further includes the limiting member 55, the first sealing member 56, the second sealing member 57, the third sealing member 58 and the fourth sealing member 59 described in the following embodiments.

[0183] Please refer to Figure 7 In some embodiments, a first through hole 1041 is provided on the base 10, and the first through hole 1041 penetrates through the side wall and / or the bottom wall of the base 10. At least a part of the mating member 63 is located inside the base 10, and the pressing member 69 passes through the first through hole 1041 and is connected to the mating member 63. It can be understood that in some embodiments, the pressing member 69 can reciprocate in the first through hole 1041 through cooperation with the mating member 63 and the reset member 65.

[0184] Specifically, in some embodiments, the shape and size of the cross-section of the pressing member 69 intercepted by a plane perpendicular to the second direction (X1 / X2) are substantially the same as the shape and size of the cross-section of the first through-hole 1041 intercepted by a plane perpendicular to the second direction (X1 / X2). Thus, not only can it be ensured that the pressing member 69 can slide relative to the base 10 in the first through-hole 1041 when being pressed, but also the gap between the pressing member 69 and the inner wall of the first through-hole 1041 can be reduced, reducing or even avoiding the entry of external water or dust into the base 10 through the gap between the pressing member 69 and the first through-hole 1041, thereby ensuring the normal operation of the structures (such as the rechargeable battery 110 and the circuit board 120, etc.) inside the base 10.

[0185] In some embodiments, the first through-hole 1041 penetrates the side wall of the base 10, so as to improve the user's convenience of use. For example, it is convenient for the user to operate the charging case 100 with one hand.

[0186] In other embodiments, the first through-hole 1041 penetrates the bottom wall of the base 10. On the one hand, it can reduce the possibility of external water or dust entering the base 10 through the first through-hole 1041, prevent the structures inside the base 10 from being damaged, and ensure the normal operation of the charging case 100; on the other hand, it is convenient for the liquid inside the base 10 to flow out through the first through-hole 1041, ensuring that the liquid does not accumulate inside the base 10 and cause damage to the structures inside the base 10.

[0187] In still other embodiments, the first through-hole 1041 penetrates the side wall and the bottom wall of the base 10. On the one hand, it can increase the size of the first through-hole 1041, ensuring that the user can extend into the base 10 through the first through-hole 1041 to apply a first acting force to the fitting 63, facilitating the user's operation; on the other hand, it is convenient for the liquid inside the base 10 to flow out through the first through-hole 1041, ensuring that the liquid does not accumulate inside the base 10 and cause damage to the structures inside the base 10.

[0188] In some embodiments, both opposite ends of the blocking member 51 are connected to the inner side of the side wall of the base 10, and the base 10 is divided into a first cavity 1021 and a second cavity 1023. The fitting 63 and the reset member 65 are both accommodated in the first cavity 1021, and the first through-hole 1041 communicates with the first cavity 1021.

[0189] Specifically, in some embodiments, the base 10 is provided with a receiving cavity 102 for receiving structures such as a rechargeable battery 110 and a circuit board 120. The blocking member 51 can divide the base 10 into a first cavity 1021 and a second cavity 1023, that is, the blocking member 51 can divide the receiving cavity 102 into a first cavity 1021 and a second cavity 1023. Among them, the cooperating member 63 and the reset member 65 are both received in the first cavity 1021, the first through hole 1041 communicates with the first cavity 1021, and structures such as the rechargeable battery 110 and the circuit board 120 are all received in the second cavity 1023. Thus, when external liquid enters the receiving cavity 102 through the first through hole 1041, the blocking member 51 can block the external liquid in the first cavity 1021, preventing the liquid from damaging structures such as the rechargeable battery 110 and the circuit board 120, thereby ensuring the normal operation of the charging case 100.

[0190] In some embodiments, a restricting member 55 is provided inside the base 10. The pressing member 69 includes an extending wall 691, and the restricting member 55 partially wraps the extending wall 691 to at least restrict the extending wall 691 from tilting towards the cover body 20.

[0191] Specifically, in some embodiments, the restricting member 55 is disposed in the first cavity 1021. One end of the restricting member 55 can be connected to the blocking member 51, and the other end can be connected to the side wall of the base 10. The extending wall 691 can be a side wall of the pressing member 69 in the third direction (Y1 / Y2), and the third direction (Y1 / Y2) is perpendicular to the first direction (Z1 / Z2) and also perpendicular to the second direction (X1 / X2).

[0192] Among them, the restricting member 55 partially wraps the extending wall 691, that is, the shape, size and contour of the side of the restricting member 55 opposite to the extending wall 691 are completely or almost completely the same as those of the extending wall 691. In this way, the restricting member 55 can cooperate with the extending wall 691 to prevent the extending wall 691 from tilting towards the cover body 20, resulting in an offset in the movement of the pressing member 69, thereby ensuring the stability of the movement of the pressing member 69 and the cooperating member 63, and further improving the stability and reliability of the operation of the key structure 60.

[0193] Further, in some embodiments, the restricting member 55 includes a first restricting member 551 and a second restricting member 553, and the extending wall 691 includes a first extending wall 693 and a second extending wall 695. The first restricting member 551 covers at least a part of the first extending wall 693 and at least restricts the first extending wall 693 from tilting towards the cover body 20, and the second restricting member 553 covers at least a part of the second extending wall 695 and at least restricts the second extending wall 695 from tilting towards the cover body 20.

[0194] Specifically, in some embodiments, the first extension wall 693 and the second extension wall 695 may be two side walls of the pressing member 69 facing away from each other in the third direction (Y1 / Y2). Compared with the limiting member 55 only including the first limiting member 551 or the second limiting member 553, the arrangement of the first limiting member 551 and the second limiting member 553 can further improve the stability of the pressing member 69 moving in the second direction (X1 / X2), prevent the pressing member 69 from tilting relative to the base 10, and improve the stability and reliability of the key structure 60 during operation.

[0195] In some embodiments, the first limiting member 551, the second limiting member 553, and the blocking member 51 together enclose a sub-chamber 10211, and the first through hole 1041 communicates with the sub-chamber 10211.

[0196] Specifically, in some embodiments, the sub-chamber 10211 is located in the first chamber 1021, and at least a part of the mating member 63 is located in the sub-chamber 10211. Thus, it can further prevent external liquid from entering the second chamber 1023 and damaging structures such as the rechargeable battery 110 and the circuit board 120 in the second chamber 1023, thereby ensuring the normal operation of the charging case 100.

[0197] In the related art, the cover 20 and the base 10 usually adopt an interference fit to improve the smoothness of the movement of the cover 20 relative to the base 10. However, having a gap between the cover 20 and the base 10 will result in poor stability when the cover 20 moves relative to the base 10 and an unsatisfactory operating feel. Please refer to Figure 3 and Figure 10 , in some embodiments of the present application, the charging case 100 further includes a damping member 70, and the damping member 70 is used to limit the degree of freedom of the extension member 23 of the cover 20 in the horizontal direction, and the horizontal direction is perpendicular to the height direction (Z1 / Z2) of the charging case 100. On the one hand, this can prevent the extension member 23 from moving or shaking in the horizontal direction, thereby improving the stability of the cover 20 moving relative to the base 10 and enhancing the operating feel; on the other hand, it can avoid large noise caused by the extension member 23 shaking relative to the base 10 in the horizontal direction during the lifting of the cover 20 relative to the base 10, thereby improving the user experience. It should be noted that, in some embodiments, the horizontal direction includes but is not limited to the second direction (X1 / X2) and the third direction (Y1 / Y2), etc.

[0198] Specifically, in some embodiments, the damping member 70 can be disposed in the moving space and cooperate with both the extension member 23 and the inner wall 131 of the connecting member 13. In this way, the damping member 70 can limit the degree of freedom of the extension member 23 in the horizontal direction, that is, the damping member 70 can block the movement of the extension member 23 in the horizontal direction, thereby improving the stability of the cover 20 moving relative to the base 10 (such as lifting).

[0199] Please combine with Figure 11 In some embodiments, the damping member 70 includes a damping body 71 and an elastic protrusion 73. The damping body 71 includes a first mating surface 711, and the first mating surface 711 mates with the extension member 23 of the cover body 20. The elastic protrusion 73 protrudes from the damping body 71, and the elastic protrusion 73 includes a second mating surface 731, and the second mating surface 731 mates with the inner wall 131 of the connecting member 13 of the base 10. The first mating surface 711 and the second mating surface 731 are located on opposite sides of the damping member 70.

[0200] Among them, the damping body 71 is a structure of the damping member 70 that can cooperate with the extension member 23. In some embodiments of the present application, the damping body 71 is connected to the side wall 231 of the extension member 23, and when the damping body 71 is connected to the extension member 23, the first mating surface 711 abuts against the side wall 231 of the extension member 23. Among them, the damping body 71 and the extension member 23 can be connected together by a detachable connection method or a non-detachable connection method. The detachable connection methods include but are not limited to snap connection or bolt connection, etc.; the non-detachable connection methods include but are not limited to bonding or welding, etc.

[0201] Exemplarily, a through connection hole 717 is provided on the damping body 71, and the fastener 106 can connect the damping body 71 to the side wall 231 of the extension member 23 through the connection hole 717. It should be noted that in some embodiments, the fastener 106 can be a bolt or a screw, etc.

[0202] The elastic protrusion 73 is a structure of the damping member 70 that can cooperate with the connecting member 13. In some embodiments of the present application, when the extension member 23 extends into the connecting member 13, the second mating surface 731 can cooperate (abut) with the inner wall 131 of the connecting member 13. In this way, the setting of the elastic protrusion 73 can limit the freedom degree of the extension member 23 in the horizontal direction, prevent the extension member 23 from moving or shaking in the horizontal direction, and thus can improve the stability when the cover body 20 moves relative to the base 10 and improve the operation feel.

[0203] It can be understood that the elastic protrusion 73 can undergo elastic deformation and generate an elastic restoring force, and the elastic restoring force generated by the elastic protrusion 73 can keep the second mating surface 731 in abutment with the inner wall 131 of the connecting member 13.

[0204] Specifically, when the extension member 23 extends into the connecting member 13, the inner wall 131 of the connecting member 13 can exert pressure on the elastic protrusion 73. Under the action of the pressure, the elastic protrusion 73 elastically deforms in the direction close to the first mating surface 711 and generates an elastic restoring force. The elastic restoring force can keep the second mating surface 731 in contact with the inner wall 131 of the connecting member 13. Thus, compared with the situation where the elastic protrusion 73 cannot elastically deform, the elastic protrusion 73 in this embodiment can avoid the problem that the second mating surface 731 cannot cooperate with the inner wall 131 of the connecting member 13 due to the unevenness of the inner wall 131 of the connecting member 13, effectively preventing the extension member 23 from moving or shaking in the horizontal direction and improving the stability when the cover body 20 moves relative to the base 10.

[0205] In some embodiments, the material of the damping member 70 is metal.

[0206] Specifically, in some embodiments, the damping body 71 and the elastic protrusion 73 are made of the same material. For example, the damping body 71 and the elastic protrusion 73 are both made of elastic metal. At this time, the damping member 70 is an elastic metal member. Among them, elastic metal includes but is not limited to titanium bronze, phosphor bronze, beryllium bronze, manganese steel, and stainless steel, etc. In other embodiments, the damping body 71 and the elastic protrusion 73 are made of different materials. For example, the material of the damping body 71 can be non-elastic metal or elastic metal; the material of the elastic protrusion 73 can be elastic metal.

[0207] It can be understood that in other embodiments, the material of the damping member 70 can also be non-metal. For example, the material of the damping member 70 can also include at least one of non-metal elastic materials such as rubber and silica gel.

[0208] In some embodiments, the damping body 71 and the elastic protrusion 73 are an integral stamping structure, that is, the damping body 71 and the elastic protrusion 73 can be formed into a whole structure by integral stamping. Thus, on the one hand, it is convenient for the processing and manufacturing of the damping member 70 and improves the production efficiency of the damping member 70; on the other hand, it can improve the connection strength between the damping body 71 and the elastic protrusion 73, reduce the possibility of the elastic protrusion 73 falling off from the damping body 71, and extend the service life of the damping member 70.

[0209] In other embodiments, the damping body 71 and the elastic protrusion 73 are a split structure, that is, the damping body 71 and the elastic protrusion 73 are two different structures. Among them, the damping body 71 and the elastic protrusion 73 can be connected together by a detachable connection method or a non-detachable connection method. The detachable connection methods include but are not limited to snap connection or bolt connection, etc.; the non-detachable connection methods include but are not limited to bonding or welding, etc.

[0210] In summary, the damping member 70 includes a damping body 71 and an elastic protrusion 73. The first mating surface 711 of the damping body 71 can cooperate with the extension member 23. The elastic protrusion 73 protrudes from the damping body 71, and the second mating surface 731 of the elastic protrusion 73 can cooperate with the inner wall 131 of the connecting member 13. In this way, the arrangement of the elastic protrusion 73 can limit the freedom degree of the extension member 23 in the horizontal direction, prevent the extension member 23 from moving or shaking in the horizontal direction, and thus can improve the stability when the cover body 20 moves relative to the base 10 and enhance the operation feel.

[0211] In addition, the arrangement of the damping member 70 can prevent the extension member 23 from shaking relative to the base 10 in the horizontal direction during the lifting of the cover body 20 relative to the base 10, resulting in a large noise, and thus can improve the user experience.

[0212] If the elastic protrusion 73 includes only one; or, the elastic protrusion 73 includes at least two, and at least two elastic protrusions 73 are arranged collinearly, then the extension member 23 is likely to deflect or shake in the connecting member 13 during the movement of the cover body 20 relative to the base 10, which will affect the stability when the cover body 20 moves relative to the base 10. For example, when the elastic protrusion 73 includes three, if the three elastic protrusions 73 are arranged collinearly along the height direction (Z1 / Z2) Z of the charging case 100, then the extension member 23 is likely to deflect around the height direction (Z1 / Z2) Z of the charging case 100 as the axis in the connecting member 13 during the movement of the cover body 20 relative to the base 10.

[0213] In some embodiments of the present application, the elastic protrusion 73 includes at least three, and the centers of the at least three elastic protrusions 73 are arranged non-collinearly. Herein, the non-collinear arrangement means that the arrangement of two or more elements (such as structural members, etc.) in space does not satisfy the collinearity condition, that is, there is no single, non-bending straight line that can pass through all these elements simultaneously. The centers of the at least three elastic protrusions 73 are arranged non-collinearly, that is, the centers of the at least three elastic protrusions 73 are not on a straight line. In this way, the at least three elastic protrusions 73 can jointly form a stable geometric shape, thereby preventing the extension member 23 from deflecting or shaking in the connecting member 13 during the movement of the cover body 20 relative to the base 10, and further improving the stability when the cover body 20 moves relative to the base 10.

[0214] Exemplarily, in certain embodiments, when the number of elastic protrusions 73 is three and the centers of the three elastic protrusions 73 are not colinearly arranged, the line connecting the centers of the three elastic protrusions 73 can form a triangle. Thus, compared with the case where the three elastic protrusions 73 are colinearly arranged, the extension member 23 is less likely to deflect or shake in the connecting member 13 when the cover body 20 moves relative to the base 10, thereby further improving the stability of the cover body 20 when it moves relative to the base 10.

[0215] In some embodiments, the elastic protrusions 73 include at least three, and the at least three elastic protrusions 73 can be evenly distributed around the center of the side wall 231 of the extension member 23. In this way, while preventing the extension member 23 from deflecting or shaking in the connecting member 13, a more stable supporting force can be provided for the extension member 23, thereby further improving the stability of the cover body 20 when it moves relative to the base 10.

[0216] See also Figure 11 In some embodiments, the elastic protrusion 73 includes a first sub-portion 733 and a second sub-portion 735 that are bent and connected to each other. The first sub-portion 733 is bent and extends from the damping body 71 in a direction away from the first mating surface 711, and the second sub-portion 735 is bent and extends from one end of the first sub-portion 733 away from the damping body 71 toward the first mating surface 711. The connection 737 between the first sub-portion 733 and the second sub-portion 735 is configured to participate in forming the second mating surface 731.

[0217] Specifically, please refer to the figure. In some embodiments, the free end 739 of the elastic protrusion 73 is spaced from the first mating surface 711, that is, the end of the second sub-section 735 away from the first sub-section 733 is spaced from the first mating surface 711, so that the elastic protrusion 73 can be elastically deformed when subjected to force. Among them, the connection 737 between the first sub-section 733 and the second sub-section 735 is the bending part between the first sub-section 733 and the second sub-section 735. When the extension member 23 extends into the connecting member 13, the connection 737 between the first sub-section 733 and the second sub-section 735 can contact the inner wall 131 of the connecting member 13, that is, the contact surface between the elastic protrusion 73 and the inner wall 131 of the connecting member 13 can be an arc surface, so that the friction between the elastic protrusion 73 and the connecting member 13 can be reduced, and the friction between the elastic protrusion 73 and the connecting member 13 is prevented from being too large, causing the cover 20 to be unable to move relative to the base 10, thereby improving the stability and reliability of the charging box 100.

[0218] It should be noted that, in certain embodiments, when there are multiple elastic protrusions 73 , the connection points 737 of the multiple elastic protrusions 73 (the connection points 737 between the first sub-portion 733 and the second sub-portion 735 ) can jointly form the second mating surface 731 .

[0219] In some embodiments, an avoidance space 715 is provided on the damping body 71, at least a part of the elastic protrusion 73 is disposed in the avoidance space 715, and a free end 739 of the elastic protrusion 73 is spaced from a bottom wall of the avoidance space 715.

[0220] Specifically, in some embodiments, the damping body 71 further includes a third mating surface 713 opposite to the first mating surface 711, and the avoidance space 715 may be recessed from the third mating surface 713 toward the first mating surface 711. Wherein, the provision of the avoidance space 715 can, on the one hand, provide a deformation space for the elastic protrusion 73 to prevent the elastic protrusion 73 from directly contacting the third mating surface 713 when being deformed by force; on the other hand, it can reduce the space size occupied by the damping body 71 and the elastic protrusion 73, which is beneficial to the miniaturization of the damper 70; and on the still other hand, it can reduce the weight of the damper 70, which is beneficial to the lightweight of the damper 70.

[0221] In some embodiments, the avoidance space 715 may be a through groove, that is, the avoidance space 715 penetrates through the first mating surface 711 and the third mating surface 713. In this case, the bottom wall of the avoidance space 715 coincides with the first mating surface 711. In other embodiments, the avoidance space 715 may be a blind groove, that is, the avoidance space 715 is recessed from the third mating surface 713 toward the first mating surface 711 and does not penetrate through the first mating surface 711.

[0222] In some embodiments, the damping body 71 has a flat plate structure. This can facilitate the processing and manufacturing of the elastic protrusion 73, ensure that when there are multiple elastic protrusions 73, the connection portions 737 of the multiple elastic protrusions 73 can be in the same plane, and improve the product yield of the damper 70.

[0223] Please refer to Figure 10 and Figure 11 , in some embodiments, an avoidance groove may be provided on a side wall 231 of the extension member 23, the avoidance groove is recessed from the side wall 231 of the extension member 23 toward the center of the extension member 23, and at least a part of the damper 70 is disposed in the avoidance groove. Thus, the provision of the avoidance groove can, on the one hand, reduce the space size occupied by the damper 70, which is beneficial to the miniaturization of the charging case 100; on the other hand, it can facilitate the installation and positioning of the damper 70, thereby improving the assembly efficiency of the charging case 100.

[0224] In some embodiments, there are two dampers 70, and the two dampers 70 are respectively disposed on opposite sides of the extension member 23 in the horizontal direction. This can further improve the stability when the cover body 20 moves relative to the base 10 and improve the operation feel.

[0225] Exemplarily, the extension member 23 includes a first side 2311, a second side 2313, a third side 2315, and a fourth side 2317 that are connected in sequence. Two damping members 70 are respectively disposed on the first side 2311 of the extension member and the third side 2315 of the extension member; alternatively, two damping members 70 are respectively disposed on the second side 2313 of the extension member and the fourth side 2317 of the extension member.

[0226] In some embodiments, two damping members 70 are respectively disposed on the first side 2311 of the extension member and the third side 2315 of the extension member, a first guiding member 41 is disposed on the second side 2313 of the extension member and / or the fourth side 2317 of the extension member, and a second guiding member 43 is disposed on the second side 1313 of the inner wall of the connecting member 13 and / or the fourth side 1317 of the inner wall of the connecting member 13. The second side 1313 of the inner wall of the connecting member 13 is opposite to the second side 2313 of the extension member, and the fourth side 1317 of the inner wall of the connecting member 13 is opposite to the fourth side 2317 of the extension member. Thereby, interference between the first guiding member 41 and the damping member 70 can be prevented, so that the cooperation between the first guiding member 41 and the second guiding member 43 can be ensured, and the normal assembly of the damping member 70 can be ensured, and further the stability of the movement of the cover body 20 relative to the base 10 can be improved.

[0227] Specifically, in certain embodiments, when the first guiding member 41 is disposed on the second side 2313 of the extension member, the second guiding member 43 is disposed on the second side 1313 of the inner wall of the connecting member 13; when the first guiding member 41 is disposed on the fourth side 2317 of the extension member, the second guiding member 43 is disposed on the fourth side 1317 of the inner wall of the connecting member 13.

[0228] It should be noted that, in certain embodiments, on the same side of the extension member 23 (such as the first side 2311 of the extension member, the second side 2313 of the extension member, the third side 2315 of the extension member, or the fourth side 2317 of the extension member), the first guiding member 41 includes at least one. Among them, the quantitative relationship between the first guiding member 41 and the second guiding member 43 can be one-to-one or one-to-many, that is, one first guiding member 41 corresponds to one second guiding member 43; or, one first guiding member 41 corresponds to multiple second guiding members 43.

[0229] In some other embodiments, two damping members 70 are respectively disposed on the first side 2311 and the third side 2315 of the extension member. The first guiding member 41 is disposed on the first side 2311 and / or the third side 2315 of the extension member. The second guiding member 43 is disposed on the first side 1311 and / or the third side 1315 of the inner wall of the connecting member 13. The first side 1311 of the inner wall of the connecting member 13 is opposite to the first side 2311 of the extension member, and the third side 1315 of the inner wall of the connecting member 13 is opposite to the third side 2315 of the extension member. The first guiding member 41 is spaced apart from the damping member 70. Thereby, interference between the first guiding member 41 and the damping member 70 can be prevented, so that the cooperation between the first guiding member 41 and the second guiding member 43 can be ensured, and the normal assembly of the damping member 70 can be ensured. Furthermore, the stability of the movement of the cover body 20 relative to the base 10 can be improved.

[0230] Please refer to Figure 3 , Figure 4 and Figure 6 , in some embodiments, the weight of the cover body 20 is less than the weight of the base 10. Thereby, it is possible to prevent the center of gravity of the charging case 100 from being too high, so that the possibility of the charging case 100 tipping over when placed can be reduced, and the stability of the placement of the charging case 100 can be improved.

[0231] In addition, the weight of the cover body 20 is less than the weight of the base 10. In this way, on the one hand, compared with the case where the weight of the cover body 20 is greater than or equal to the weight of the base 10, the overall weight of the charging case 100 is smaller, so that it is convenient for the user to carry; on the other hand, it is possible to prevent the cover body 20 from being too heavy to move relative to the base 10 with difficulty or even impossible, so that the normal use of the charging case 100 can be ensured.

[0232] Specifically, in some embodiments, the weight of the cover body 20 being less than the weight of the base 10 may be: the weight of the structure of the cover body 20 itself is less than the weight of the structure of the base 10 itself; or, the weight of the overall structure formed by the cover body 20 and the structures disposed on the cover body 20 is less than the weight of the structure of the base 10 itself; or, the weight of the overall structure formed by the cover body 20 and the structures disposed on the cover body 20 is less than the weight of the overall structure formed by the base 10 and the structures disposed on the base 10 (for example, the structure formed by the base 10 and the circuit board 120 and the rechargeable battery 110 disposed on the base 10). It can be understood that in some embodiments of the present application, no additional structures are provided on the cover body 20.

[0233] In some embodiments, the orthographic projection of the cover body 20 on the base 10 is completely within the range of the base 10, that is, the projection of the cover body 20 in the height direction (Z1 / Z2) perpendicular to the charging case 100 is within the projection of the base 10 in the height direction (Z1 / Z2) perpendicular to the charging case 100. Thereby, the center of gravity of the charging case 100 can be within the range of the base 10. Compared with the case where the center of gravity of the charging case 100 is outside the range of the base 10, the possibility of the charging case 100 tipping over when placed is lower, thus improving the stability of the charging case 100 when placed. It should be noted that the height direction (Z1 / Z2) of the charging case 100 can be: the direction from the cover body 20 to the base 10 when the charging case 100 is in a non-operating state; or the direction from the base 10 to the cover body 20.

[0234] In other embodiments, the projection of the cover body 20 in the height direction (Z1 / Z2) perpendicular to the charging case 100 coincides with the projection of the base 10 in the height direction (Z1 / Z2) perpendicular to the charging case 100. Thereby, the center of gravity of the charging case 100 can be within the range of the base 10. Compared with the case where the center of gravity of the charging case 100 is outside the range of the base 10, the possibility of the charging case 100 tipping over when placed is lower, thus improving the stability of the charging case 100 when placed.

[0235] In the embodiments of the present application, only the cross-section of the cover body 20 intercepted by a plane perpendicular to the height direction (Z1 / Z2) of the charging case 100 is smaller than the cross-section of the base 10 intercepted by a plane perpendicular to the height direction (Z1 / Z2) of the charging case 100 is taken as an example for illustration.

[0236] In certain embodiments, at least part of the cover body 20 is a hollow structure.

[0237] Specifically, in certain embodiments, a cavity (including a first cavity 210 and a second cavity 230) can be provided inside the cover body 20. Thus, compared with the cover body 20 being a solid structure, the weight of the cover body 20 is lighter, thereby preventing the center of gravity of the charging case 100 from being closer to the cover body 20 than to the base 10, and further improving the stability of the charging case 100 when placed. In addition, at least part of the cover body 20 being a hollow structure can also reduce the material usage, thereby reducing the production cost of the charging case 100.

[0238] Further, please refer to Figure 6, in some embodiments, the main body 21 and / or the extension 23 are hollow structures. Specifically, in one example, the main body 21 is a hollow structure. At this time, a first cavity 210 may be provided inside the main body 21. In another example, the extension 23 is a hollow structure. At this time, a second cavity 230 may be provided inside the extension 23. In yet another example, both the main body 21 and the extension 23 are hollow structures. At this time, a first cavity 210 may be provided inside the main body 21, and a second cavity 230 may be provided inside the extension 23.

[0239] More specifically, the main body 21 may include a first sub - part 211 and a second sub - part 213. If the main body 21 is a hollow structure, then when the first sub - part 211 and the second sub - part 213 are combined, the first sub - part 211 and the second sub - part 213 jointly form a first cavity 210. Thus, compared with the lid 20 being a solid structure, that is, compared with there being no first cavity 210 after the first sub - part 211 and the second sub - part 213 are combined, the weight of the lid 20 is lighter.

[0240] In one example, the first sub - part 211 and the second sub - part 213 are an integral structure, that is, the first sub - part 211 and the second sub - part 213 can be formed into a whole by an integral molding method. In this way, the sealing performance of the main body 21 can be improved, preventing external water or dust from entering the main body 21, thereby improving the stability and reliability of the charging box 100 during operation.

[0241] In another example, the first sub - part 211 and the second sub - part 213 are a split structure, that is, the first sub - part 211 and the second sub - part 213 are two different structures. Among them, the first sub - part 211 and the second sub - part 213 can be combined together by a detachable connection method or a non - detachable connection method. The detachable connection methods include but are not limited to snap connection or bolt connection, etc.; the non - detachable connection methods include but are not limited to bonding or welding, etc.

[0242] Please refer to Figure 6 , in some embodiments, the lid 20 is provided with a reinforcing rib 27, and the reinforcing rib 27 protrudes and extends from the inner wall of the lid 20 towards the center of the lid 20. Among them, the setting of the reinforcing rib 27 can increase the structural strength of the lid 20 and reduce the possibility of the lid 20 deforming and being damaged. In addition, compared with the reinforcing rib 27 protruding and extending from the lid 20 in a direction away from the lid 20, the reinforcing rib 27 in this embodiment will not be seen by the user, so the appearance effect of the charging box 100 can be improved.

[0243] In some embodiments of the present application, the reinforcing rib 27 can protrude and extend from the first sub - part 211 towards the center of the cavity (the first cavity 210 jointly formed after the combination of the first sub - part 211 and the second sub - part 213); and / or, the reinforcing rib 27 can protrude and extend from the second sub - part 213 towards the center of the cavity. In this way, while enhancing the structural strength of the cover 20, the weight of the cover 20 can be reduced. It can be understood that when the cover 20 is provided with the reinforcing rib 27, the total weight of the cover 20 and the reinforcing rib 27 is also less than the weight of the base 10.

[0244] Please refer to Figure 3 and Figure 6 , in some embodiments, the volume of the cover 20 is smaller than the volume of the base 10; and / or, the wall thickness of the cover 20 is smaller than the wall thickness of the base 10. This can make the cover 20 lighter in weight, thereby preventing the center of gravity of the charging case 100 from being closer to the cover 20 than the base 10, that is, making the center of the charging case 100 lower, and further reducing the possibility of the charging case 100 tipping over when placed, and improving the stability of the charging case 100 when placed.

[0245] Exemplarily, when the volume of the cover 20 is smaller than the volume of the base 10 and the materials of the cover 20 and the base 10 are the same, the weight of the cover 20 is less than the weight of the base 10; or, when the volume of the cover 20 is smaller than the volume of the base 10 and the wall thickness of the cover 20 is smaller than the wall thickness of the base 10, the weight of the cover 20 is less than the weight of the base 10.

[0246] In some embodiments, the volume of the cover 20 is smaller than the volume of the base 10; and / or, the density of the material of the cover 20 is less than the density of the material of the base 10. This can make the cover 20 lighter in weight, thereby preventing the center of gravity of the charging case 100 from being closer to the cover 20 than the base 10, that is, making the center of the charging case 100 lower, and further reducing the possibility of the charging case 100 tipping over when placed, and improving the stability of the charging case 100 when placed.

[0247] Exemplarily, when the volume of the cover 20 is smaller than the volume of the base 10 and the density of the material of the cover 20 is less than the density of the material of the base 10, the weight of the cover 20 is less than the weight of the base 10. It can be understood that in other examples, when the volume of the cover 20 is equal to the volume of the base 10 and the density of the material of the cover 20 is less than the density of the material of the base 10, the weight of the cover 20 is also less than the weight of the base 10.

[0248] In summary, in some embodiments of the present application, when at least one of the following conditions is met, the weight of the cover 20 is less than the weight of the base 10: at least a part of the cover 20 is a hollow structure; the volume of the cover 20 is less than the volume of the base 10; the wall thickness of the cover 20 is less than the wall thickness of the base 10; the density of the material of the cover 20 is less than the density of the material of the base 10.

[0249] Exemplarily, when at least a part of the cover 20 is a hollow structure, the volume of the cover 20 is less than the volume of the base 10, the wall thickness of the cover 20 is less than the wall thickness of the base 10, and the density of the material of the cover 20 is less than the density of the material of the base 10, the weight of the cover 20 is less than the weight of the base 10, thereby preventing the center of gravity of the charging case 100 from being too high, reducing the possibility of the charging case 100 tipping over when placed, and improving the stability of the charging case 100 when placed.

[0250] Please refer to Figure 6 and Figure 12 , in some embodiments, the charging case 100 further includes a position detection component 80 and a prompt component 90. The position detection component 80 is disposed on the cover 20 and the base 10, and is used to detect the moving distance of the cover 20 relative to the base 10. The prompt component 90 changes the state of the prompt component 90 based on the moving distance detected by the position detection component 80, and the state of the prompt component 90 at least includes the triggering state of the prompt component 90.

[0251] Among them, the position detection component 80 is a structure for detecting the moving distance of the cover 20 relative to the base 10. The position detection component 80 is disposed on the cover 20 and the base 11, that is, the position detection component 80 detects the moving distance of the cover 20 relative to the base 10 through the cooperation between a first detection member (such as a magnetic member 83) disposed in the cover 20 and a second detection member (such as a Hall sensor 81) disposed in the base 10.

[0252] Specifically, the ways for the position detection component 80 to detect the moving distance include but are not limited to detecting magnetic flux, detecting pressure, detecting infrared rays, etc. Among them, the number of the first detection member and the second detection member can be one or more, which is not limited in the present application. In one example, the number of the first detection member and the second detection member is the same, and in another example, the number of the first detection member and the second detection member is different.

[0253] The prompting component 90 changes its state based on the moving distance detected by the position detection component 80. That is, when the moving distance of the cover body 20 relative to the base 10 is different, the state of the prompting component 90 can be different. Among them, the state of the prompting component 90 at least includes the triggering state of the prompting component 90. In the triggering state, the prompting component 90 can emit an indication signal to represent different parameters of the charging case 100, and the parameters include but are not limited to the consumed power, the remaining power, and the temperature, etc.

[0254] The prompting component 90 includes at least one prompting element. The prompting element changes its state based on the moving distance detected by the position detection component 80. The indication signals emitted by the prompting element include but are not limited to indication light and indication sound, etc. In one example, the number of prompting elements in the prompting component 90 can be one. In another example, the number of prompting elements in the prompting component 90 is at least two. In the embodiment where the number of prompting elements is multiple, the indication signals emitted by the multiple prompting elements can be the same or different.

[0255] In summary, the charging case 100 can use the position detection component 80 provided on the cover body 20 and the base body 11 to detect the moving distance of the cover body 20 relative to the base 10. The prompting component 90 changes its state based on the detected moving distance to represent different parameters of the charging case 100, so that the user can intuitively obtain the state of the charging case 100 corresponding to the parameters of the charging case 100, realizing real-time monitoring of the charging case 100.

[0256] Please refer to Figure 6 , in some embodiments, the position detection component 80 includes a Hall sensor 81 and a magnetic member 83. The magnetic member 83 is disposed in the cover body 20 and moves with the cover body 20. The Hall sensor 81 is disposed in the base 10. The Hall sensor 81 cooperates with the magnetic member 83, and the Hall sensor 81 detects the moving distance of the cover body 20 relative to the base 10 through the change of the magnetic flux.

[0257] Specifically, in the present application, the position detection component 80 detects the moving distance of the cover body 20 relative to the base 10 through the change of the magnetic flux. The change of the magnetic flux representing the moving distance of the cover body 20 relative to the base 10 can be represented by the change of the magnetic flux of a group of Hall sensors 81 and magnetic members 83, or can be represented by the change of the magnetic flux of multiple groups of Hall sensors 81 and magnetic members 83 in a certain combination manner.

[0258] In one example, the magnetic member 83 is disposed within the cover body 20, and the Hall sensor 81 is disposed within the base 10. The Hall sensor 81 disposed within the base 10 senses the change in the magnetic flux of the magnetic member 83 disposed within the cover body 20 to detect the moving distance of the cover body 20 relative to the base 10. In another example, the Hall sensor 81 is disposed within the cover body 20, and the magnetic member 83 is disposed within the base 10. The Hall sensor 81 disposed within the cover body 20 senses the change in the magnetic flux of the magnetic member 83 disposed within the base 10 to detect the moving distance of the cover body 20 relative to the base 10. In still another example, both the magnetic member 83 and the Hall sensor 81 are disposed within the cover body 20, and both the magnetic member 83 and the Hall sensor 81 are also disposed within the base 10. The Hall sensor 81 disposed within the base 10 senses the change in the magnetic flux of the magnetic member 83 disposed within the cover body 20, and the Hall sensor 81 disposed within the cover body 20 senses the change in the magnetic flux of the magnetic member 83 disposed within the base 10. The Hall sensor 81 is small in size, easy to integrate into the charging case 100, and has low power consumption, which is suitable for portable devices such as the charging case 100 and helps to extend the battery life of the charging case 100.

[0259] In some embodiments, when the moving distance indicates that the cover body 20 is in the pressed position, the state of the prompting component 90 is the sleep state. When the moving distance indicates that the cover body 20 moves to a predetermined position, the state of the prompting component 90 is the triggered state, and an indication signal is emitted to indicate the charging parameters of the charging case 100. The pressed position is the position where the cover body 20 presses the charging member placed on the base 10.

[0260] Wherein, the predetermined position includes the release position and any position between the pressed position and the release position. The release position is the position where the cover body 20 has the maximum moving distance relative to the base 10, and the pressed position is the position where the cover body 20 presses the charging member placed on the base 10. In this way, the timing for the indicator light component 91 to emit the indication signal can be set more diversely and flexibly.

[0261] Specifically, when the cover body 20 is in the pressed position, the state of the prompting component 90 is the sleep state, which can characterize that the cover body 20 is in the pressed position. When the cover body 20 is in the predetermined position, the state of the prompting component 90 is the triggered state, and an indication signal is emitted to indicate the parameters of the charging case 100. That is, in the triggered state, the prompting component 90 can emit an indication signal to indicate the parameters of the charging case 100 through the indication signal, thereby indicating the state of the charging case 100.

[0262] Please refer to Figure 6 and Figure 12, in some embodiments, the prompting component 90 is an indicator light component 91. The states of the prompting component 90 include a sleep state and a triggered state. The indication signal includes indication light. When the moving distance indicates that the cover body 20 is in the pressed position, the state of the indicator light component 91 is the sleep state. When the moving distance indicates that the cover body 20 moves to a predetermined position, the state of the indicator light component 91 is the triggered state, and emits indication light to indicate the charging parameters of the charging case 100.

[0263] The indicator light component 91 includes at least one prompting element. The prompting element changes its state based on the moving distance detected by the position detection component 80. In one embodiment, the indication signal emitted by the prompting element is indication light. The prompting element includes, but is not limited to, an LED lamp, a laser diode, or other types of light-emitting elements. In an example, the number of prompting elements in the prompting component 90 may be one. In another example, the number of prompting elements in the prompting component 90 may be at least two. In the embodiments where the number of prompting elements is multiple, the types of the multiple prompting elements may be the same or different. The cross-sectional shape of the prompting element may be circular, oval, triangular, quadrilateral, or other polygons, etc., which is not limited herein.

[0264] When the moving distance indicates that the cover body 20 is in the pressed position, the state of the indicator light component 91 is the sleep state. Among them, in the sleep state, the indicator light component 91 does not emit indication light, that is, the indicator light component 91 is extinguished. When the cover body 20 switches from the pressed position to the predetermined position, the indicator light component 91 switches from the sleep state to the triggered state and emits indication light, that is, the indicator light component 91 is lit. In the triggered state, the parameters of the indication light emitted by the indicator light component 91 include, but are not limited to, the brightness, color, and blinking frequency of the indication light, etc. These parameters of the indication light can reflect the parameters of the charging case 100.

[0265] In some embodiments, the indication light has different brightnesses, and different brightnesses represent different parameter values of the same parameter of the charging case 100.

[0266] Specifically, the parameters of the indication light include the brightness of the indication light. When the moving distance indicates that the cover body 20 moves to the predetermined position and the state of the indicator light component 91 is the triggered state and emits indication light, the indication light represents different parameter values of the same parameter of the charging case 100 through different brightnesses. At this time, the parameters of the charging case 100 include, but are not limited to, the power consumption, remaining power, and temperature of the charging case 100, etc. Correspondingly, the parameter values include, but are not limited to, the power consumption value, remaining power value, and temperature value. The relationship between the brightness and different parameter values of the same parameter of the charging case 100 can be positively correlated or negatively correlated.

[0267] For example, in an embodiment where the parameter of the charging case 100 is the remaining power, the parameter value is the remaining power value, and the brightness of the indicating light is positively correlated with the remaining power, the brightness of the indicating light at least includes a first brightness, a second brightness, and a third brightness, where the first brightness is greater than the second brightness, and the second brightness is greater than the third brightness. The remaining power value of the charging case 100 at least includes a first remaining power value, a second remaining power value, and a third remaining power value, where the first remaining power value is greater than the second remaining power value, and the second remaining power value is greater than the third remaining power value. Thus, when the moving distance indicates that the cover 20 moves to a predetermined position, the brightness of the indicating light is the first brightness (e.g., 100), indicating that the remaining power of the charging case 100 is the first remaining power value (e.g., 90%); the brightness of the indicating light is the second brightness (e.g., 80), indicating that the remaining power of the charging case 100 is the second remaining power value (e.g., 80%); the brightness of the indicating light is the third brightness (e.g., 60), indicating that the remaining power of the charging case 100 is the third remaining power value (e.g., 60%). Thus, the charging case 100 can represent different parameter values of the same parameter of the charging case 100 through different brightnesses of the indicating light, enabling the user to obtain different states of the charging case 100 according to the different brightnesses of the indicating light.

[0268] In some embodiments, the indicating light has different colors, and different colors represent different parameter values of the same parameter of the charging case 100.

[0269] Specifically, the parameter of the indicating light includes the color of the indicating light. When the moving distance indicates that the cover 20 moves to a predetermined position, and the state of the indicator light assembly 91 is the triggered state and emits the indicating light, the indicating light represents different parameter values of the same parameter of the charging case 100 through different colors. At this time, the parameters of the charging case 100 include but are not limited to the power consumption, remaining power, and temperature of the charging case 100. Correspondingly, the parameter values include but are not limited to the power consumption value, remaining power value, and temperature value.

[0270] For example, in an embodiment where the parameter of the charging case 100 is temperature and the parameter value is a temperature value, the colors at least include a first color (e.g., red), a second color (e.g., yellow), and a third color (e.g., blue). The temperature values at least include a first temperature value, a second temperature value, and a third temperature value, where the first temperature value is greater than the second temperature value, and the second temperature value is greater than the third temperature value. Thus, when the moving distance indicates that the cover 20 has moved to a predetermined position, the color of the indicating light is the first color, indicating that the temperature of the charging case 100 is the first temperature value (e.g., 40 °C); the color of the indicating light is the second color, indicating that the temperature of the charging case 100 is the second temperature value (e.g., 30 °C); the color of the indicating light is the third color, indicating that the temperature of the charging case 100 is the third temperature value (e.g., 25 °C). Thus, the charging case 100 can represent different parameter values of the same parameter of the charging case 100 through different colors of the indicating light, enabling the user to obtain different states of the charging case 100 based on the different colors of the indicating light.

[0271] In some embodiments, the indicating light has different blinking frequencies, and different blinking frequencies represent different parameter values of the same parameter of the charging case 100.

[0272] Specifically, the parameter of the indicating light includes the blinking frequency of the indicating light. When the moving distance indicates that the cover 20 has moved to a predetermined position, and the state of the indicator light assembly 91 is the triggered state and emits the indicating light, the indicating light represents different parameter values of the same parameter of the charging case 100 through different blinking frequencies. At this time, the parameters of the charging case 100 include but are not limited to the power consumption, remaining power, and temperature of the charging case 100. Correspondingly, the parameter values include but are not limited to the power consumption value, remaining power value, and temperature value. The relationship between the blinking frequency and different parameter values of the same parameter of the charging case 100 can be positively correlated or negatively correlated.

[0273] For example, in an implementation where the parameter of the charging case 100 is the remaining power, the parameter value is the remaining power value, and the blinking frequency of the indicating light is negatively correlated with the remaining power, the blinking frequency at least includes a first blinking frequency, a second blinking frequency, and a third blinking frequency, where the first blinking frequency is less than the second blinking frequency, and the second blinking frequency is less than the third blinking frequency. The remaining power value at least includes a first remaining power value, a second remaining power value, and a third remaining power value, where the first remaining power value is greater than the second remaining power value, and the second remaining power value is greater than the third remaining power value. Thus, when the moving distance indicates that the cover 20 moves to a predetermined position, the blinking frequency of the indicating light is the first blinking frequency (10 MHZ), indicating that the remaining power of the charging case 100 is the first remaining power value (90%); the blinking frequency (50 MHZ) of the indicating light is the second blinking frequency, indicating that the remaining power of the charging case 100 is the second remaining power value (50%); the blinking frequency of the indicating light is the third blinking frequency (80 MHZ), indicating that the remaining power of the charging case 100 is the third remaining power value (20%). Thus, the charging case 100 can represent different parameter values of the same parameter of the charging case 100 through different blinking frequencies of the indicating light, enabling the user to obtain different states of the charging case 100 according to different blinking frequencies of the indicating light.

[0274] In some implementations, the indicating light assembly 91 includes a plurality of indicating lights 911 for emitting indicating light, and the indicating light emitted by different numbers of indicating lights 911 represents different parameter values of the same parameter of the charging case 100.

[0275] Specifically, the indicating light assembly 91 includes a plurality of indicating lights 911, and the number of indicating lights 911 is not limited. When the moving distance indicates that the cover 20 moves to a predetermined position and the indicating light assembly 91 is in a triggered state and emits indicating light, the indicating light assembly 91 can represent different parameters of the charging case 100 through the number of indicating lights 911 that are in the triggered state and emit indicating light 911. The parameters of the charging case 100 include but are not limited to the power consumption, remaining power, and temperature of the charging case 100. Correspondingly, the parameter values include but are not limited to the power consumption value, remaining power value, and temperature value. The relationship between the number of indicating lights 911 and the parameter values of the same parameter includes but is not limited to positive correlation and negative correlation.

[0276] For example, in an implementation where the parameter of the charging case 100 is temperature, the parameter value is the temperature value, and the number of indicator lights is positively correlated with the temperature. Among the multiple indicator lights 911, the number of indicator lights 911 emitting indicator light at least includes a first number, a second number, and a third number, where the first number is greater than the second number, and the second number is greater than the third number. The temperature value at least includes a first temperature value, a second temperature value, and a third temperature value, where the first temperature value is greater than the second temperature value, and the second temperature value is greater than the third temperature value. Thus, when the movement distance indicates that the cover 20 moves to a predetermined position, the number of indicator lights 911 emitting indicator light being the first number (e.g., 4) indicates that the temperature of the charging case 100 is the first temperature value (e.g., 40°C); the number of indicator lights 911 emitting indicator light being the second number (e.g., 3) indicates that the temperature of the charging case 100 is the second temperature value (e.g., 30°C); the number of indicator lights 911 emitting indicator light being the third number (e.g., 2) indicates that the temperature of the charging case 100 is the third temperature value (e.g., 25°C). Thus, the charging case 100 can represent different parameter values of the same parameter of the charging case 100 through the number of indicator lights 911 emitting indicator light in the indicator light assembly 91, enabling the user to obtain different states of the charging case 100 according to the number of indicator lights 911.

[0277] Please refer to Figure 6 and Figure 12 , in some implementations, the indicator light assembly 91 includes multiple indicator lights 911, and the indicator lights 911 are used to emit indicator light, and the indicator lights of different indicator lights 911 are used to represent different parameters of the charging case 100.

[0278] Specifically, the indicator light assembly 91 includes a plurality of indicator lights 911, and the number of the indicator lights 911 is not limited. When the moving distance indicates that the cover body 20 moves to a predetermined position and the state of the indicator light assembly 91 is in a triggered state and emits an indicator light, different indicator lights can represent different parameters of the charging case 100. The parameters of the charging case 100 include but are not limited to the power consumption, remaining power, and temperature of the charging case 100, etc. Correspondingly, the parameter values include but are not limited to the power consumption value, remaining power value, and temperature value. Among them, when different indicator lights represent the parameters of the charging case 100, the parameters of the indicator lights used can be the same or different. For example, when the indicator light assembly 91 includes a first indicator light 9111, a second indicator light 9112, and a third indicator light 9113, the parameters of the charging case 100 include a first parameter (such as power consumption), a second parameter (such as remaining power), and a third parameter (such as temperature) of the charging case 100, where the first parameter, the second parameter, and the third parameter are different. In one implementation, the indicator light emitted by the first indicator light 9111 is used to represent the power consumption of the charging case 100, the indicator light emitted by the second indicator light 9112 is used to represent the remaining power of the charging case 100, and the indicator light emitted by the third indicator light 9113 is used to represent the temperature of the charging case 100. In an example, different brightnesses of the indicator light emitted by the first indicator light 9111 represent different power consumption values of the power consumption of the charging case 100, different colors of the indicator light emitted by the second indicator light 9112 represent different remaining power values of the remaining power of the charging case 100, and different blinking frequencies of the indicator light emitted by the third indicator light 9113 represent different temperature values of the temperature of the charging case 100.

[0279] The indicator light assembly 91 represents different parameters of the charging case 100 through the indicator lights of different indicator lights 911. Thus, the indicator light assembly 91 can transmit at least one state of the charging case 100 and enrich the information transmitted by the indicator light assembly 91.

[0280] In some implementations, the indicator light assembly 91 includes a plurality of indicator lights, and the indicator lights are used to emit indicator lights. The number of blinks of the indicator lights of different indicator lights represents different parameters.

[0281] Specifically, the indicator light assembly 91 includes a plurality of indicator lights 911, and the number of the indicator lights 911 is not limited. The number of blinks represents the blinking frequency. When the moving distance indicates that the cover body 20 moves to a predetermined position and the state of the indicator light assembly 91 is in a triggered state and emits an indicator light, the indicator lights emitted by different indicator lights 911 can represent different parameters of the charging case 100 through different blinking frequencies. The parameters of the charging case 100 include but are not limited to the power consumption, remaining power, and temperature of the charging case 100, etc. Correspondingly, the parameter values include but are not limited to the power consumption value, remaining power value, and temperature value.

[0282] For example, when the indicator light assembly 91 includes a first indicator light 9111, a second indicator light 9112, and a third indicator light 9113, the blinking frequency of the first indicator light 9111 is the first blinking frequency, the blinking frequency of the second indicator light 9112 is the second blinking frequency, and the blinking frequency of the third indicator light 9113 is the third blinking frequency, wherein the first blinking frequency, the second blinking frequency, and the third blinking frequency are different. The parameters of the charging case 100 include a first parameter (such as the consumed power), a second parameter (such as the remaining power), and a third parameter (such as the temperature) of the charging case 100, wherein the first parameter, the second parameter, and the third parameter are different. In one implementation, the first blinking frequency represents the consumed power of the charging case 100, the second blinking frequency represents the remaining power of the charging case 100, and the third blinking frequency represents the temperature of the charging case 100. The indicator light assembly 91 represents different parameters of the charging case 100 through the number of blinks of the indicator light emitted by different indicator lights. Thus, the indicator light assembly 91 can transmit at least one state of the charging case 100, enriching the information transmitted by the indicator light assembly 91.

[0283] In some implementations, the indicator light assembly 91 includes an indicator light 911 and a light guide member 913. The light guide member 913 covers the indicator light 911. The indicator light 911 is used to emit indicator light, and the light guide member 913 is used to guide the indicator light outside the base 10. Thus, the light guide member 913 can control the propagation direction of the indicator light, ensuring that the indicator light is emitted to a preset area and direction, and improving the accuracy of the indicator signal (i.e., the indicator light) transmitted by the indicator light assembly 91.

[0284] Specifically, the indicator light 911 is disposed inside the base 10 and electrically connected to the circuit board 120. The indicator light 911 includes, but is not limited to, an LED lamp, a laser diode, or other types of light-emitting elements. In one example, the number of indicator lights 911 in the indicator light assembly 91 can be one. In another example, the number of indicator lights 911 in the indicator light assembly 91 can be at least two. In an implementation where the number of indicator lights 911 is multiple, the types of the multiple indicator lights 911 can be the same or different.

[0285] The light guide member 913 is at least partially located inside the base 10 and covers the indicator light 911. The number of light guide members 913 can be one or multiple, which is not limited in this application. The light guide member 913 can at least change the optical path of the indicator light. Thus, the indicator light can be guided outside the base 10. In one example, one light guide member 913 covers one indicator light 911. In another example, multiple light guide members 913 cover one indicator light 911. In still another example, one light guide member 913 covers multiple indicator lights 911. In addition, in other implementations, the light guide member 913 can also change parameters of the indicator light such as the color and / or brightness of the indicator light.

[0286] Please refer to Figure 13 , in some embodiments, the central axis M of the indicating light emitted by the indicating lamp 911 and the central axis N of the indicating light emitted from the light guide member 913 have an included angle.

[0287] Specifically, the light guide member 913 can change the optical path of the indicating light, that is, the central axis M of the indicating light emitted by the indicating lamp 911 (i.e., the central axis of the optical path) and the central axis N of the indicating light emitted from the light guide member 913 do not coincide and have a certain included angle. The light guide member 913 changes the transmission path of the indicating light emitted by the indicating lamp 911, making the installation of the indicating lamp 911 flexible and leaving more installation space for other components. In this embodiment, the included angle between the central axis M and the central axis N is 90 degrees. In other embodiments, the included angle between the central axis M and the central axis N can also be 45 degrees, 60 degrees, or 75 degrees, etc.

[0288] Furthermore, in some embodiments, the included angle between the central axis M of the indicating light emitted by the indicating lamp 911 and the central axis N of the indicating light emitted from the light guide member 913 is greater than or equal to 30° and less than or equal to 120°.

[0289] Among them, the included angle between the central axis M of the indicating light emitted by the indicating lamp 911 and the central axis N of the indicating light emitted from the light guide member 913 can be 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°. If the included angle between the central axis M of the indicating light emitted by the indicating lamp 911 and the central axis N of the indicating light emitted from the light guide member 913 is less than 30°, the change of the optical path of the indicating light by the light guide member 913 is limited, and the indicating light is not easily emitted outside the charging case 100. If the included angle between the central axis M of the indicating light emitted by the indicating lamp 911 and the central axis N of the indicating light emitted from the light guide member 913 is greater than 120°, the optical path of the indicating light emitted from the light guide member 913 and the optical path of the indicating light emitted from the indicating lamp 911 deviate too much, which is likely to cause users to misunderstand the position of the indicating light and is not conducive to users to identify the information of the indicating light. When the included angle between the central axis M of the indicating light emitted by the indicating lamp 911 and the central axis N of the indicating light emitted from the light guide member 913 is greater than or equal to 30° and less than or equal to 120°, the light guide member 913 changes the optical path of the indicating light emitted by the indicating lamp 911, and the change angle is appropriate, which is conducive to users to identify the information of the indicating light and can also make the installation of the indicating lamp 911 flexible and leave more installation space for other components.

[0290] Please refer to Figure 12 and Figure 13, in some embodiments, a second through hole 1043 is provided on the side wall of the base 10. The light guide member 913 is at least partially received in the second through hole 1043. A first seal 56 is provided on the indicator light assembly 91. The first seal 56 is sleeved on the light guide member 913 and is located between the inner wall of the second through hole 1043 and the outer wall of the light guide member 913.

[0291] Specifically, the shape and size of the cross-section of the portion of the light guide member 913 located in the second through hole 1043 intercepted by a plane perpendicular to the third direction (Y1 / Y2) are substantially the same as the shape and size of the cross-section of the second through hole 1043 intercepted by a plane perpendicular to the third direction (Y1 / Y2). Thereby, the gap between the light guide member 913 and the inner wall of the second through hole 1043 can be reduced, and the entry of external water or dust into the base 10 through the gap between the light guide member 913 and the second through hole 1043 can be reduced or even avoided, so as to ensure the normal operation of the structures (such as the rechargeable battery 110 and the circuit board 120, etc.) inside the base 10.

[0292] Please refer to Figure 14 and Figure 15 , the first seal 56 is sleeved on the light guide member 913 and is located between the outer side wall 1711 of the light guide member 913 and the inner side wall of the second through hole 1043, and can seal the gap between the outer side wall 1711 of the light guide member 913 and the inner side wall of the second through hole 1043.

[0293] The material of the first seal 56 includes but is not limited to metals, plastics, rubbers, etc., and is not limited in this application. In one example, the number of the first seals 56 can be one. In another example, the number of the first seals 56 can be at least two. In embodiments where the number of the first seals 56 is multiple, the cross-sectional shapes of the multiple first seals 56 can be the same or different.

[0294] Thus, in the case where external fluid enters the second through hole 1043, the first seal 56 can block the external fluid in the portion of the second through hole 1043 close to the outside world, preventing the external fluid from entering the inside of the base 10 through the second through hole 1043 and damaging structures such as the indicator light assembly 91, the rechargeable battery 110, and the circuit board 120, so as to ensure the normal operation of the charging case 100.

[0295] In some embodiments, the indicator light assembly 91 includes a plurality of indicator lights 911, the indicator light assembly 91 includes a plurality of light guide members 913, the plurality of light guide members 913 are arranged at intervals in sequence along a direction perpendicular to the moving direction of the cover body 20 relative to the base 10, and the indicator lights and the light guide members 913 are respectively arranged corresponding to each other in the moving direction.

[0296] Specifically, in an embodiment where the indicator light assembly 91 includes a plurality of indicator lights 911 and a plurality of light guide members 913, the plurality of light guide members 913 are arranged at intervals in sequence along a direction perpendicular to the moving direction of the cover body 20 relative to the base 10. It should be noted that in some embodiments, the moving direction of the cover body 20 relative to the base 10 may be the first direction (Z1 / Z2); the direction perpendicular to the moving direction of the cover body 20 relative to the base 10 may include, but is not limited to, the second direction (X1 / X2) and the third direction (Y1 / Y2), etc. In this embodiment, only the case where the direction perpendicular to the moving direction of the cover body 20 relative to the base 10 is the third direction (Y1 / Y2) is taken as an example for illustration.

[0297] Among them, the spaced-apart light guide members 913 are arranged neatly and are easy to identify, which can improve the readability of the indication signal emitted by the indicator light assembly 91 and has a good visual effect. The indicator lights 911 and the light guide members 913 are respectively arranged corresponding to each other in the moving direction, which can ensure that each indicator light 911 has the light guide members 913 to conduct light uniformly. The cooperation of each indicator light 911 and the corresponding light guide member 913 can ensure that the indication light propagates along a specific direction, reducing the scattering and waste of the indication light.

[0298] In some embodiments, a second through hole 1043 is provided on the side wall of the base 10. The indicator light assembly 91 includes a plurality of indicator lights 911. The light guide members 913 include a plurality of light guide portions 9131 and a connecting portion 9133. The plurality of light guide portions 9131 are arranged at intervals in sequence along a direction perpendicular to the moving direction of the cover body 20 relative to the base 10. The first ends of the light guide portions 9131 are received in the second through hole 1043, the second ends of the plurality of light guide portions 9131 are all connected to the connecting portion 9133, and the plurality of indicator lights 911 and the plurality of light guide portions 9131 are respectively arranged corresponding to each other in the moving direction.

[0299] Specifically, the number of the light guide parts 9131, the second through holes 1043, and the connecting parts 9133 is not limited in this application. Among them, the number of the second through holes 1043 may or may not correspond to that of the light guide parts 9131. In this application, when the number of the second through holes 1043 corresponds to that of the light guide parts 9131, the assembly process of the light guide parts 9131 can be simplified. Each light guide part 9131 corresponds to one second through hole 1043, which helps to isolate the indicating light of different light guide parts 9131 and reduce light crosstalk and mutual interference. The first end of the light guide part 9131 is placed in the second through hole 1043, and the second through hole 1043 can restrict the indicating light emitted from the light guide part 9131, further controlling the emission direction of the indicating light and avoiding the scattering of the indicating light. The second ends of multiple light guide parts 9131 are all connected to the connecting part 9133, which can make the light guide member 913 formed by the light guide parts 9131 and the connecting part 9133 an integral structure, facilitating processing and shaping. The design of connecting the light guide parts 9131 to the connecting part 9133 simplifies the assembly process. During installation, only the connecting part 9133 needs to be connected to the circuit board 120, instead of connecting each light guide part 9131 separately.

[0300] In some embodiments, the indicator light assembly 91 includes multiple indicator lights 911. The indicator light assembly 91 further includes a first spacer 915. Multiple indicator lights 911 are mounted on the circuit board 120, the first spacer 915 is mounted on the circuit board 120, the light guide member 913 is mounted on the first spacer 915, the first spacer 915 is provided with multiple spaced-apart spacer grooves 9151, and multiple indicator lights are respectively received in different spacer grooves 9151.

[0301] Specifically, the number of the first spacers 915 may be one or multiple. In this application, the case where the number of the first spacers 915 is one is described. The light guide member 913 is mounted on the first spacer 915. In some embodiments, the light guide member 913 and the first spacer 915 are an integral structure, that is, the light guide member 913 and the first spacer 915 are a whole structure. Thereby, the bonding strength between the light guide member 913 and the first spacer 915 can be improved, preventing the separation of the light guide member 913 and the first spacer 915 during the operation of the indicator light assembly 91, and thus ensuring the stability and reliability of the operation of the indicator light assembly 91. In other embodiments, the light guide member 913 and the first spacer 915 are a split structure, that is, the light guide member 913 and the first spacer 915 are two different structures. In one example, the light guide member 913 and the first spacer 915 can be combined together by a detachable connection method, and the detachable connection method includes but is not limited to snap connection or screw connection, etc. In another example, the light guide member 913 and the first spacer 915 can be combined together by a non-detachable connection method, and the non-detachable connection method includes but is not limited to bonding or welding, etc.

[0302] The plurality of spacing grooves 9151 are spaced from each other, and the plurality of spacing grooves 9151 are not connected in the second direction (X1 / X2) or the third direction (Y1 / Y2). Thus, the indicating lights emitted by the indicating lamps accommodated in different spacing grooves 9151 do not interfere with each other, and the spacing grooves 9151 can prevent the indicating lights from being cross-lit with each other during the process of exiting from the indicating lamps to the light guide member 913.

[0303] In some embodiments, the first spacer 915 is made of a light-absorbing material.

[0304] Specifically, the light-absorbing material includes, but is not limited to, black plastics and rubbers. The first spacer 915 being made of a light-absorbing material may mean that the entire first spacer 915 is made of a light-absorbing material, thereby improving the light-blocking effect and preventing cross-lighting between the indicating lamps; or it may mean that only a part of the first spacer 915 is made of a light-absorbing material, which can reduce costs while preventing cross-lighting between the indicating lamps.

[0305] In some embodiments, the inner sidewall of the spacing groove 9151 is made of a light-absorbing material.

[0306] Specifically, the inner sidewall of the spacing groove 9151 can absorb at least part of the indicating light emitted by the indicating lamp, avoiding some of the indicating light from entering the optical path of other indicating lights and forming stray light that affects the indicating signal emitted by the indicating lamp assembly 91, so as to further enhance the light-blocking effect of the spacing groove 9151.

[0307] In some embodiments, the inner sidewall of the spacing groove 9151 is provided with a light-absorbing layer.

[0308] Specifically, the light-absorbing layer can absorb at least part of the indicating light emitted by the indicating lamp 911, avoiding some of the indicating light from entering the optical path of other indicating lights and forming stray light that affects the indicating signal emitted by the indicating lamp assembly 91, so as to further enhance the light-blocking effect of the spacing groove 9151. The light-absorbing layer can be one layer or multiple layers. In embodiments where the light-absorbing layer is multiple layers, the structures of different layers can have different characteristics to absorb indicating lights of different wavelengths. The light-absorbing layer is easy to disassemble and replace.

[0309] In some embodiments, the indicating lamp assembly 91 further includes a second spacer 917, and the second spacer 917 is disposed on the first spacer 915 and is at least located between two adjacent light guide members 913 or light guide portions 9131.

[0310] The second spacer 917 is disposed on the first spacer 915 and is at least located between two adjacent light guide members 913 or light guide portions 9131, which can prevent the indicating lights from being cross-lit with each other during the process of exiting from the light guide member 913 to the outside of the base 10, thereby further preventing the indicating lights exposed from the light guide member 913 or the light guide portion 9131 from being cross-lit.

[0311] In some embodiments, the second spacer 917 is made of a light-absorbing material.

[0312] Specifically, the light-absorbing material includes, but is not limited to, black plastics and rubbers. The second spacer 917 being made of a light-absorbing material can mean that the entire second spacer 917 is made of a light-absorbing material, thereby improving the light-blocking effect and preventing light leakage between the indicator lights; or that only a part of the second spacer 917 is made of a light-absorbing material, reducing costs while ensuring the effect of preventing light leakage between the indicator lights.

[0313] In some embodiments, a light-absorbing layer is provided on the outer sidewall 1711 of the second spacer 917.

[0314] Specifically, the light-absorbing material includes, but is not limited to, black plastics and rubbers. The second spacer 917 being made of a light-absorbing material can mean that the entire second spacer 917 is made of a light-absorbing material, thereby improving the light-blocking effect and preventing light leakage between the indicator lights; or that only a part of the second spacer 917 is made of a light-absorbing material, reducing costs while ensuring the effect of preventing light leakage between the indicator lights.

[0315] Please refer to Figure 6 and Figure 12 , in some embodiments, the prompting component 90 is the response component 93. The states of the prompting component 90 include a sleep state and a trigger state, and the indication signal includes an indication sound. When the moving distance indicates that the cover body 20 is in the pressed position, the state of the response component 93 is the sleep state. When the moving distance indicates that the cover body 20 moves to a predetermined position, the state of the response component 93 is the trigger state, and an indication sound is emitted to indicate the charging parameters of the charging case 100. The pressed position is the position where the cover body 20 presses the charging member placed on the base 10.

[0316] Wherein, the response component 93 includes at least one prompting member, and the prompting member changes its state based on the moving distance detected by the position detection component 80. In one embodiment, the indication signal emitted by the prompting member is an indication sound, and the prompting member includes, but is not limited to, a buzzer 931, a speaker, a voice chip, or other types of sound-emitting elements. In one example, the number of prompting members in the response component 93 can be one. In another example, the number of prompting members in the response component 93 can be at least two. In embodiments where the number of prompting members is multiple, the types of the multiple prompting members can be the same or different.

[0317] Exemplarily, when the moving distance indicates that the cover body 20 is in the pressed position, the response component 93 is in a sleep state. Among them, in the sleep state, the response component 93 does not emit an indication sound; when the cover body 20 switches from the pressed position to a predetermined position, the response component 93 switches from the sleep state to the trigger state and emits an indication sound. In the trigger state, the parameters of the indication sound emitted by the response component 93 include but are not limited to the duration, decibel, and frequency of the indication sound, etc. These parameters of the indication sound can reflect the parameters of the charging case 100.

[0318] Please refer to Figure 6 and Figure 12 , in some embodiments, the indication sound has different durations, and different durations represent different parameter values of the same parameter of the charging case 100.

[0319] Specifically, the parameters of the indication sound include the duration of the indication sound. When the moving distance indicates that the cover body 20 moves to a predetermined position and the response component 93 is in the trigger state and emits an indication sound, the indication sound represents different parameter values of the same parameter of the charging case 100 through different durations. At this time, the parameters of the charging case 100 include but are not limited to the power consumption, remaining power, and temperature of the charging case 100, etc. Correspondingly, the parameter values include but are not limited to the power consumption value, remaining power value, and temperature value. The relationship between the duration and the different parameter values of the same parameter of the charging case 100 can be positively correlated or negatively correlated. Thus, the charging case 100 can represent different parameter values of the same parameter of the charging case 100 through different durations of the indication sound.

[0320] For example, in an implementation where the parameter of the charging case 100 is the remaining power, the parameter value is the remaining power value, and the duration of the indication sound is negatively correlated with the remaining power, the duration of the indication sound at least includes a first duration, a second duration, and a third duration, where the first duration is less than the second duration, and the second duration is less than the third duration. The remaining power value of the charging case 100 at least includes a first remaining power value, a second remaining power value, and a third remaining power value, where the first remaining power value is greater than the second remaining power value, and the second remaining power value is greater than the third remaining power value. Thus, when the moving distance indicates that the cover 20 moves to a predetermined position, the duration of the indication sound is the first duration (e.g., 3 seconds), indicating that the remaining power of the charging case 100 is the first remaining power value (e.g., 90%); the duration of the indication sound is the second duration (e.g., 5 seconds), indicating that the remaining power of the charging case 100 is the second remaining power value (e.g., 80%); the duration of the indication sound is the third duration (e.g., 10 seconds), indicating that the remaining power of the charging case 100 is the third remaining power value (e.g., 5%). Thus, the charging case 100 can represent different parameter values of the same parameter of the charging case 100 through different durations of the indication sound, enabling the user to obtain different states of the charging case 100 based on the different durations of the indication sound.

[0321] Please refer to Figure 6 and Figure 12 , in some implementations, the indication sound has different frequencies, and different frequencies represent different parameter values of the same parameter of the charging case 100.

[0322] Specifically, the parameter of the indication sound includes the frequency of the indication sound. When the moving distance indicates that the cover 20 moves to a predetermined position and the state of the response component 93 is the triggered state and emits an indication sound, the indication sound represents different parameter values of the same parameter of the charging case 100 through different frequencies. At this time, the parameters of the charging case 100 include but are not limited to the power consumption, remaining power, and temperature of the charging case 100, and correspondingly, the parameter values include but are not limited to the power consumption value, remaining power value, and temperature value. The relationship between the frequency and different parameter values of the same parameter of the charging case 100 can be positively correlated or negatively correlated.

[0323] For example, in an implementation where the parameter of the charging case 100 is the remaining power, the parameter value is the remaining power value, and the frequency of the indication sound is negatively correlated with the remaining power, the frequency of the indication sound includes at least a first frequency, a second frequency, and a third frequency, where the first frequency is less than the second frequency, and the second frequency is less than the third frequency. The remaining power value of the charging case 100 includes at least a first remaining power value, a second remaining power value, and a third remaining power value, where the first remaining power value is greater than the second remaining power value, and the second remaining power value is greater than the third remaining power value. Thus, when the movement distance indicates that the cover 20 moves to a predetermined position, when the frequency of the indication sound is the first frequency (20 HZ), it indicates that the remaining power of the charging case 100 is the first remaining power value (80%); when the frequency of the indication sound is the second frequency (40 HZ), it indicates that the remaining power of the charging case 100 is the second remaining power value (60%); when the frequency of the indication sound is the third frequency (60 HZ), it indicates that the remaining power of the charging case 100 is the third remaining power value (40%). Thus, the charging case 100 can represent different parameter values of the same parameter of the charging case 100 through different frequencies of the indication sound, enabling the user to obtain different states of the charging case 100 according to different frequencies of the indication sound.

[0324] Please refer to Figure 6 , in some implementations, the response component 93 includes a plurality of buzzers 931, and the buzzers 931 are used to emit an indication sound, and the indication sounds emitted by different numbers of buzzers 931 represent different parameter values of the same parameter of the charging case 100.

[0325] Specifically, the response component 93 includes a plurality of buzzers 931, and the number of the buzzers 931 is not limited. When the movement distance indicates that the cover 20 moves to a predetermined position and the state of the response component 93 is the trigger state and emits an indication sound, the response component 93 can represent different parameters of the charging case 100 through the number of buzzers 931 in the trigger state and emitting an indication sound. The parameters of the charging case 100 include but are not limited to the power consumption, remaining power, and temperature of the charging case 100. Correspondingly, the parameter values include but are not limited to the power consumption value, remaining power value, and temperature value. The relationship between the number of buzzers 931 and the parameter values of the same parameter includes but is not limited to positive correlation and negative correlation.

[0326] For example, in an embodiment where the parameter of the charging case 100 is temperature, the parameter value is the temperature value, and the number of buzzers 931 is positively correlated with the temperature. Among the multiple buzzers 931, the number of buzzers 931 that emit an indication sound at least includes a first number, a second number, and a third number. Among them, the first number is greater than the second number, and the second number is greater than the third number. The temperature value at least includes a first temperature value, a second temperature value, and a third temperature value. Among them, the first temperature value is greater than the second temperature value, and the second temperature value is greater than the third temperature value. Thus, when the movement distance indicates that the cover 20 moves to a predetermined position, the number of buzzers 931 that emit an indication sound being the first number (for example, 4) indicates that the temperature of the charging case 100 is the first temperature value (for example, 40 °C); the number of buzzers 931 that emit an indication sound being the second number (for example, 3) indicates that the temperature of the charging case 100 is the second temperature value (for example, 30 °C); the number of buzzers 931 that emit an indication sound being the third number (for example, 2) indicates that the temperature of the charging case 100 is the third temperature value (for example, 25 °C). Thus, the charging case 100 can represent different parameter values of the same parameter of the charging case 100 by the number of buzzers 931 in the response component 93 that are in a triggered state and emit an indication light, enabling the user to obtain different states of the charging case 100 according to the number of buzzers 931.

[0327] Please refer to Figure 5 , in some embodiments, the response component 93 includes multiple buzzers 931, and the buzzers 931 are used to emit an indication sound, and the indication sounds of different buzzers 931 are used to represent different parameters of the charging case 100.

[0328] Specifically, the response component 93 includes a plurality of buzzers 931, and the number of buzzers 931 is not limited. When the movement distance indicates that the cover body 20 moves to a predetermined position, and the response component 93 is in a triggered state and emits an indication sound, different indication sounds can represent different parameters of the charging case 100. The parameters of the charging case 100 include but are not limited to the power consumption, remaining power, and temperature of the charging case 100, etc. Correspondingly, the parameter values include but are not limited to the power consumption value, remaining power value, and temperature value. Among them, when different indication sounds represent the parameters of the charging case 100, the parameters of the indication sounds used can be the same or different. For example, when the response component 93 includes a first buzzer 931, a second buzzer 931, and a third buzzer 931, the parameters of the charging case 100 include a first parameter (such as power consumption), a second parameter (such as remaining power), and a third parameter (such as temperature) of the charging case 100, where the first parameter, the second parameter, and the third parameter are different. In one implementation, the indication sound emitted by the first buzzer 931 is used to represent the power consumption of the charging case 100, the indication sound emitted by the second buzzer 931 is used to represent the remaining power of the charging case 100, and the indication sound emitted by the third buzzer 931 is used to represent the temperature of the charging case 100. In an example, different durations of the indication sound emitted by the first buzzer 931 represent different power consumption values of the power consumption of the charging case 100, different frequencies of the indication sound emitted by the second buzzer 931 represent different remaining power values of the remaining power of the charging case 100, and different decibels of the indication sound emitted by the third buzzer 931 represent different temperature values of the temperature of the charging case 100. The response component 93 represents different parameters of the charging case 100 through the indication sounds of different buzzers 931. Thus, the response component 93 can transmit at least one state of the charging case 100 and enrich the information transmitted by the response component 93.

[0329] Please refer to Figure 3 and Figure 14 , in some embodiments, a third through hole 1045 is provided on the base 10. The charging case 100 further includes a data exchange terminal 901 and a second seal 57. The second seal 57 is sleeved on the data exchange terminal 901 and is located between the outer sidewall 1711 of the data exchange terminal 901 and the inner sidewall of the third through hole 1045. The second seal 57 is used to seal the gap between the outer sidewall 1711 of the data exchange terminal 901 and the inner sidewall of the third through hole 1045.

[0330] Specifically, the shape and size of the cross-section of the data exchange terminal 901 intercepted by a plane perpendicular to the third direction (Y1 / Y2) are substantially the same as those of the cross-section of the third through-hole 1045 intercepted by a plane perpendicular to the third direction (Y1 / Y2). Thereby, the gap between the data exchange terminal 901 and the inner wall of the third through-hole 1045 can be reduced, and the entry of external water or dust into the base 10 through the gap between the data exchange terminal 901 and the third through-hole 1045 can be reduced or even avoided, so as to ensure the normal operation of the structures (such as the rechargeable battery 110 and the circuit board 120, etc.) inside the base 10.

[0331] The second seal 57 is sleeved on the data exchange terminal 901 and is located between the outer sidewall of the data exchange terminal 901 and the inner sidewall of the second through-hole 1043, and can seal the gap between the outer sidewall of the data exchange terminal 901 and the inner sidewall of the second through-hole 1043. Thus, when external fluid enters the third through-hole 1045, the second seal 57 can block the external fluid in the part of the third through-hole 1045 close to the outside world, preventing the external fluid from entering the inside of the base 10 through the third through-hole 1045 and damaging structures such as the rechargeable battery 110 and the circuit board 120, so as to ensure the normal operation of the charging case 100.

[0332] Please refer to Figure 3 、 Figure 14 、 Figure 16 and Figure 17 In some embodiments, a fourth through-hole 1047 is provided on the base 10. The first electrical connector 17 includes a charging terminal 171. One end of the charging terminal 171 is located inside the base 10, and the other end of the charging terminal 171 extends out of the base 10 from the fourth through-hole 1047. The charging case 100 further includes a third seal 58. The third seal 58 is provided between the inner sidewall of the fourth through-hole 1047 and the outer sidewall 1711 of the charging terminal 171, and the third seal 58 is used to block fluid from entering the base 10 between the inner sidewall of the fourth through-hole 1047 and the outer sidewall 1711 of the charging terminal 171.

[0333] The fourth through-hole 1047 communicates the inside and the outside of the charging case 100. The fourth through-hole 1047 is provided on the top wall of the base 10. The cross-sectional shape (the plane intercepted by the XY plane) of the fourth through-hole 1047 can be circular, elliptical, triangular, quadrilateral or other polygons, etc., which is not limited herein. In one example, the number of the fourth through-holes 1047 can be one, and the charging terminal 171 is installed in the fourth through-hole 1047. In another example, the number of the fourth through-holes 1047 can be at least two. At this time, each fourth through-hole 1047 is provided with a charging terminal 171. Thereby, the density of the charging terminals 171 can be increased, and the electrical connection stability of the components of the charging case 100 can be improved.

[0334] Please combine with Figure 2 , the charging terminal 171 is installed in the fourth through hole 1047 to realize the electrical connection between the internal components of the charging case 100 and the external components of the charging case 100. One end of the charging terminal 171 is located inside the base 10, and the other end of the charging terminal 171 extends out of the base 10 from the fourth through hole 1047. One end of the charging terminal 171 located outside the base 10 is used to connect to the second electrical connector 280 to realize the electrical connection with the earphone 200, and one end of the charging terminal 171 located inside the base 10 is used to connect to other components inside the charging case 100. The installation direction of the charging terminal 171 inserted into the fourth through hole 1047 is the first direction (Z1 / Z2).

[0335] There is a certain difference between the size of the fourth through hole 1047 and the size of the charging terminal 171 as a reserved size during installation, so that the charging terminal 171 can be installed in the fourth through hole 1047. Therefore, after the charging terminal 171 is installed in the fourth through hole 1047, there is a certain gap between the inner side wall of the fourth through hole 1047 and the outer side wall 1711 of the charging terminal 171.

[0336] The third seal 58 is provided between the fourth through hole 1047 and the charging terminal 171 to seal the gap between the inner side wall of the fourth through hole 1047 and the outer side wall 1711 of the charging terminal 171 to prevent fluid from flowing into the charging case 100 through the gap. The third seal 58 can be made of various materials such as rubber, silica gel, polypropylene, etc. The third seal 58 can be one or more, and is not limited in this application. In the embodiment of the present application, the number of the third seals 58, the number of the charging terminals 171, and the number of the fourth through holes 1047 correspond one by one.

[0337] The third seal 58 can be formed separately and then sleeved on the charging terminal 171, or can be sleeved on the outer side wall 1711 of the charging terminal 171 in the form of overmolding, or can be directly formed on the outer side wall 1711 of the charging terminal 171 together with the charging terminal 171 by a two-color injection molding process. At this time, the materials of the charging terminal 171 and the third seal 58 can be the same or different.

[0338] The third seal 58 is installed in the gap between the inner side wall of the fourth through hole 1047 of the charging case 100 and the outer side wall 1711 of the charging terminal 171, which can seal the gap between the inner side wall of the fourth through hole 1047 and the outer side wall 1711 of the charging terminal 171, prevent fluid from flowing into the interior of the charging case 100, and improve the waterproof level of the charging case 100. In addition, the third seal 58 has a low cost and does not occupy additional installation space.

[0339] In some embodiments, the third seal 58 and the charging terminal 171 are of a split structure. The third seal 58 is sleeved on the outer sidewall 1711 of the charging terminal 171 and is located between the outer sidewall 1711 of the charging terminal 171 and the inner sidewall of the fourth through hole 1047.

[0340] The third seal 58 and the charging terminal 171 are of a split structure, that is, the third seal 58 and the charging terminal 171 are two different structures. In one example, the third seal 58 and the charging terminal 171 can be combined together by a detachable connection method. The detachable connection methods include but are not limited to snap connection or screw connection, etc. In another example, the third seal 58 and the charging terminal 171 can be combined together by a non-detachable connection method. The non-detachable connection methods include but are not limited to bonding or welding, etc. The split structure of the third seal 58 and the charging terminal 171 facilitates the replacement of the third seal 58 and the charging terminal 171.

[0341] In some embodiments, the third seal 58 is a sealing ring.

[0342] Specifically, in the embodiment where the third seal 58 is separately formed and sleeved on the charging terminal 171, the third seal 58 can be a sealing ring. The sealing ring is sleeved on the outer sidewall 1711 of the charging terminal 171 to seal the gap between the inner sidewall of the fourth through hole 1047 and the outer sidewall 1711 of the charging terminal 171. The sealing ring is easy to replace and has a low cost.

[0343] The material of the sealing ring can be a material with certain elasticity, such as rubber. Among them, the rubber materials include but are not limited to natural rubber, nitrile rubber, fluororubber, polyurethane rubber, ethylene propylene diene monomer rubber or silicone rubber, etc. The elastic sealing ring can not only achieve a waterproof effect, but also absorb vibration and impact for the charging terminal 171, avoiding deformation of the charging terminal 171 caused by external force.

[0344] In some embodiments, the third seal 58 and the charging terminal 171 are of an integral structure.

[0345] Specifically, the third seal 58 and the charging terminal 171 are of an integral structure, that is, the third seal 58 and the charging terminal 171 are a whole structure. Thereby, the bonding strength between the third seal 58 and the charging terminal 171 can be improved, preventing the separation of the third seal 58 and the charging terminal 171 during the operation of the charging case 100, thus ensuring the stability and reliability of the operation of the charging case 100, and also being able to further improve the sealing and waterproof effect.

[0346] In some embodiments, the materials of both the third seal 58 and the charging terminal 171 are metals.

[0347] Specifically, metals have high strength and good wear resistance. Using metal as the material for the third seal 58 and the charging terminal 171 can extend the service life of the third seal 58 and the charging terminal 171. In an embodiment where both the third seal 58 and the charging terminal 171 are made of metal, the metal materials used for the third seal 58 and the charging terminal 171 can be the same or different. For example, it can be understood that the material of the charging terminal 171 can be a material with good electrical conductivity to ensure the electrical connection between the charging terminal 171 and the second electrical connector 280. The third seal 58 can be a material with good chemical stability, such as copper. Copper has strong rust prevention ability and will not be corroded by impurities in water, which can ensure the waterproof effect of the third seal 58.

[0348] In an embodiment where the third seal 58 and the charging terminal 171 are of an integral structure and both the third seal 58 and the charging terminal 171 are made of metal, the integrally formed and metal third seal 58 and charging terminal 171 can form an interference fit with the fourth through hole 1047, thereby sealing the gap between the outer wall 1711 of the charging terminal 171 and the inner wall of the fourth through hole 1047 to achieve a waterproof effect.

[0349] In an embodiment where the third seal 58 and the charging terminal 171 are of an integral structure and both the third seal 58 and the charging terminal 171 are made of copper, the integrally formed and copper-made third seal 58 and charging terminal 171 can not only form an interference fit with the fourth through hole 1047, thereby sealing the gap between the outer wall 1711 of the charging terminal 171 and the inner wall of the fourth through hole 1047 to achieve a waterproof effect, but also copper has strong electrical conductivity and strong rust prevention ability and will not be corroded by impurities in water, which can not only ensure the waterproof effect but also ensure the stability of the connection between the charging terminal 171 and the second electrical connector 280.

[0350] In some embodiments, the first electrical connector 17 includes an electrical connector 173. The electrical connector 173 is installed on the circuit board 120 (accommodated in the base 10) and is electrically connected to the charging terminal 171. It should be noted that in some embodiments, each first electrical connector 17 includes one charging terminal 171 and one electrical connector 173.

[0351] The electrical connector 173 can connect the charging terminal 171 and the circuit board 120. The electrical connector 173 can be one or more. One electrical connector 173 can correspond to multiple charging terminals 171, or one electrical connector 173 can correspond to one charging terminal 171, or multiple electrical connectors 173 can correspond to one charging terminal 171. In the implementation manner of the application, one electrical connector 173 corresponds to one charging terminal 171. The material of the electrical connector 173 includes but is not limited to copper, aluminum, nickel, etc. The electrical connector 173 has a certain elastic deformation ability and can elastically deform in the first direction (Z1 / Z2), so as to better connect the charging terminal 171 and the circuit board 120. When the charging terminal 171 is inserted into the fourth through hole 1047, the charging terminal 171 will apply a force in the first direction (Z1 / Z2) to the electrical connector 173, and the electrical connector 173 can generate elastic deformation according to the insertion depth of the charging terminal 171 in the first direction (Z1 / Z2) (that is, the distance between the charging terminal 171 and the circuit board 120), so that the electrical connector 173 and the charging terminal 171 fit better. That is, the electrical connector 173 can adjust its own elastic deformation degree according to the distance between the charging terminal 171 and the circuit board 120, so as to ensure the stability of the electrical connection between the charging terminal 171 and the circuit board 120.

[0352] After the charging terminal 171 is inserted into the fourth through hole 1047, if the charging terminal 171 is subjected to a force in the first direction (Z1 / Z2) and moves closer to the circuit board 120, the electrical connector 173 can provide an opposite force and isolate the charging terminal 171 and the circuit board 120, avoiding the charging terminal 171 directly squeezing the circuit board 120 and causing damage to the circuit board 120. After the charging terminal 171 is inserted into the fourth through hole 1047, if the charging terminal 171 is subjected to a force opposite to the first direction (Z1 / Z2), resulting in the distance between the charging terminal 171 and the circuit board 120 becoming farther in the first direction (Z1 / Z2), the electrical connector 173 can recover part of its elastic deformation and continue to maintain an electrical connection with the charging terminal 171, so as to ensure the stability of the electrical connection between the charging terminal 171 and the circuit board 120.

[0353] The electrical connector 173 is installed on the circuit board 120 and is electrically connected to the charging terminal 171. The electrical connector 173 can adapt to different distances between the charging terminal 171 and the circuit board 120 through elastic deformation, so as to maintain a stable electrical connection between the charging terminal 171 and the circuit board 120. In addition, using the electrical connector 173 can avoid connecting the charging terminal 171 and the circuit board 120 by the SMT process, saving costs.

[0354] In some embodiments, the electrical connector 173 includes a conductive body 1731 and a conductive elastic piece 1733. The conductive body 1731 is mounted on the circuit board 120. The conductive elastic piece 1733 extends away from the circuit board 120 from the conductive body 1731 and then bends back towards the circuit board 120 to form a protruding portion, and the protruding portion abuts against the engaging portion 613 of the charging terminal 171.

[0355] Specifically, the conductive elastic piece 1733 has a certain elastic deformation ability and can be elastically deformed in the first direction (Z1 / Z2), so as to better abut against the charging terminal 171, and thus better connect the charging terminal 171 and the circuit board 120. The conductive body 1731 is mounted on the circuit board 120, which can ensure the stable connection between the electrical connector 173 and the circuit board 120, and make the electrical connector 173 not easily fall off the circuit board 120.

[0356] In the embodiments of the present application, the conductive body 1731 and the conductive elastic piece 1733 are of an integral structure, that is, the conductive body 1731 and the conductive elastic piece 1733 are a whole structure, thereby improving the bonding strength between the conductive body 1731 and the conductive elastic piece 1733, preventing the conductive body 1731 and the conductive elastic piece 1733 from separating during the operation of the electrical connector 173, and thus ensuring the stability and reliability of the operation of the electrical connector 173. In some other embodiments, the conductive body 1731 and the conductive elastic piece 1733 are of a split structure, that is, the conductive body 1731 and the conductive elastic piece 1733 are two different structures.

[0357] In one example, the conductive body 1731 and the conductive elastic piece 1733 can be combined together by a detachable connection method. The detachable connection method includes but is not limited to snap connection or threaded connection, etc. In another example, the conductive body 1731 and the conductive elastic piece 1733 can be combined together by a non-detachable connection method. The non-detachable connection method includes but is not limited to bonding or welding, etc. The protruding portion abuts against the charging terminal 171 and has a certain elasticity, that is, the conductive elastic piece 1733 can be elastically deformed in the first direction (Z1 / Z2) to change its relative position with the charging terminal 171 to adapt to different relative positions with the conductive elastic piece 1733, ensuring the electrical connection with the charging terminal 171, and thus making the connection between the electrical connector 173 and the charging terminal 171 more stable.

[0358] In some embodiments, the outer side surface of the top wall of the base 10 is a curved surface. There are multiple charging terminals 171 and multiple electrical connectors 173. The contact positions of at least two electrical connectors 173 with the corresponding charging terminals 171 are at different heights relative to the circuit board 120, so that the outer side surfaces of the multiple charging terminals 171 are flush.

[0359] Specifically, in some embodiments, the outer side surface of the base 10 is a curved surface, that is, the outer side surface of the base 10 is not a flat surface, which can enable the outer side surface of the base 10 to adapt to different environments. For example, it can be adapted to earphones 200 with different outer contours. The outer side surfaces of the plurality of charging terminals 171 are flush, and can be well electrically connected to the second electrical connector 280 on the earphone 200. Further, the distances between the outer side surfaces of the plurality of charging terminals 171 and the outer side surface of the base 10 are the same, which can make the outer side surfaces of the plurality of charging terminals 171 flat and avoid the charging terminals 171 protruding and being knocked.

[0360] Please refer to Figure 14 , in some embodiments, a fifth through hole 1049 is provided at the top of the seat body 111, and the upper cover 113 covers the fifth through hole 1049. The charging box 100 further includes a fourth seal 59. The fourth seal 59 is disposed on the top of the seat body 111 and is located between the seat body 111 and the upper cover 113. The fourth seal 59 is used to seal the gap between the seat body 111 and the upper cover 113.

[0361] The seat body 111 and the upper cover 113 can be combined together by a detachable connection method. The detachable connection method includes but is not limited to snap connection or threaded connection, etc. In another example, the seat body 111 and the upper cover 113 can be combined together by a non-detachable connection method. The non-detachable connection method includes but is not limited to bonding or welding, etc.

[0362] Among them, the fourth seal 59 is disposed on the top of the seat body 111 and is located between the seat body 111 and the upper cover 113, and can be disposed on the top of the seat body 111 and is located between the seat body 111 and the upper cover 113. Thus, in the case where external fluid enters the fifth through hole 1049, the fourth seal 59 can block the external fluid from the part where the fifth through hole 1049 communicates with the outside world, preventing the external fluid from entering the inside of the base 10 through the fifth through hole 1049 and damaging structures such as the charging battery 110 and the circuit board 120, thereby ensuring the normal operation of the charging box 100.

[0363] In some embodiments, the fourth seal 59 is a sealing ring.
