Description

Charging case and earphone system Technical Field

[0001] This application relates to the field of electronic device technology, and more specifically, to a charging case and earphone system. Background Technology

[0002] In related technologies, users typically utilize charging cases for functions such as charging or storing earphones. For example, when the earphones are low on battery or no longer needed, users can place them in the charging case. The charging case includes a base and a lid, with the lid capable of lifting relative to the base to facilitate the placement and removal of the earphones. However, if the lifting range of the lid relative to the base is unrestricted, excessive force applied by the user to the charging case may cause the lid to exert excessive impact on the base or excessive pressure on the earphones, resulting in damage to the charging case and / or the earphones.

[0003] Summary of the Invention

[0004] This application provides a charging case and earphone system to solve at least one of the aforementioned technical problems.

[0005] The charging case provided in this application includes a base, a cover, a rechargeable battery, and a limiting component. The base has a bearing surface for supporting a component to be charged. The cover is connected to the base and can move up and down relative to the base to switch between a pressed position and a released position. When the cover is in the pressed position, it presses the component to be charged against the bearing surface. The rechargeable battery is disposed in the base. The limiting component is disposed on the cover and / or the base, and limits the lifting range of the cover relative to the base.

[0006] The headphone system provided in this application includes headphones and a charging case, the charging case being used to charge the headphones. The charging case includes a base, a cover, a rechargeable battery, and a limiting component. The base has a bearing surface for supporting the component to be charged. The cover is connected to the base and can be raised and lowered relative to the base to switch between a pressed position and a released position. When the cover is in the pressed position, the cover presses the component to be charged against the bearing surface. The rechargeable battery is disposed in the base. The limiting component is disposed in the cover and / or the base, and the limiting component is used to limit the lifting stroke of the cover relative to the base.

[0007] In the charging case and earphone system of this application embodiment, the setting of the limiting component can limit the lifting stroke of the cover relative to the base. This can prevent the cover from generating excessive impact force on the base or excessive pressure force on the earphone when the user applies too much force to the charging case, thereby reducing the possibility of damage to the charging case and / or earphones and extending the service life of the charging case and earphones.

Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly. In one example, they can be a fixed connection, a detachable connection, or an integral connection; they can be a mechanical connection, an electrical connection, or a connection that allows communication between them; they can be a direct connection or an indirect connection through an intermediate medium; they can be the internal connection of two elements or the interaction between two elements.

[0031] Referring to Figure 1, the headphone system 300 provided in this embodiment includes a device to be charged and a charging case 100. The charging case 100 is used to charge the device to be charged. It should be noted that in some embodiments, the device to be charged includes, but is not limited to, headphones, watches, wristbands, game controllers, and cameras. In the embodiments shown below, only headphones 200 are used as an example of the device to be charged.

[0032] Since the headphone system 300 in this embodiment includes a charging case 100, it is understood that the headphone system 300 has at least 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 described below.

[0033] In some embodiments of this application, the device to be charged includes air conduction headphones and bone conduction headphones. Air conduction headphones are headphones 200 that transmit sound through air vibrations. Bone conduction headphones are headphones 200 that convert sound into different mechanical vibrations and transmit sound waves through the skull, bony labyrinth, inner ear synovial fluid, cochlea, auditory center, etc. It is understood that the headphones 200 can be worn on the user's ear and can be used with devices such as mobile phones, computers, smart wearable devices (such as smartwatches, smart bracelets, smart glasses, smart helmets, etc.), head-mounted displays, and virtual reality devices.

[0034] It should be noted that the user's ear includes the external auditory canal, concha, cymba conchae, triangular fossa, helix, and antitragus. Among these, 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 extending medially from the external auditory meatus deep within the concha to the tympanic membrane.

[0035] Furthermore, in some embodiments, the earphone 200 includes a transducer assembly 210 (including a first transducer assembly 2101 and a second transducer assembly 2103), which is a structure in the earphone 200 used to enable 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 worn, in which case 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 part of the concha, cymba conchae, and triangular fossa when the earphone 200 is worn. It should be noted that the embodiments described below only use a bone conduction earphone as an example.

[0036] Furthermore, 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 back 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 attached to the left and right ears. The battery compartment 220 may be disposed between the first ear hook assembly 240 and the back hook assembly 260, and the control compartment 230 may be disposed between the second ear hook assembly 250 and the back hook assembly 260. 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.

[0037] Referring to 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 transfer the electrical energy of the rechargeable battery 110 to the earphone 200 to charge the earphone 200.

[0038] Furthermore, referring to Figures 2 and 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.

[0039] Specifically, in some embodiments, when the first electrical connector 17 and the second electrical connector 280 are electrically connected, the charging case 100 and the earphone 200 can perform functions such as power transmission and data transmission. For example, when the first electrical connector 17 and the second electrical connector 280 are electrically connected, the circuit board 120 can transmit the power 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.

[0040] Furthermore, in some embodiments, the first electrical connector 17 includes a plurality of components, and the second electrical connector 280 includes a plurality of components. When the earphone 200 is placed in the charging case 100, the plurality of first electrical connectors 17 and the plurality of second electrical connectors 280 are electrically connected in a one-to-one correspondence.

[0041] Specifically, in some embodiments, a portion of the plurality of first electrical connectors 17 is used for power transmission, and another portion is used for signal transmission; correspondingly, a portion of the plurality of second electrical connectors 280 is used for power transmission, and another portion is used for signal transmission. The plurality of first electrical connectors 17 are arranged side-by-side on the charging case 100. This arrangement, compared to a non-side-by-side arrangement, reduces the space occupied by the first electrical connectors 17, making the structure more compact and facilitating the miniaturization of the charging case 100. Furthermore, it facilitates the alignment of the first electrical connectors 17 and the second electrical connectors 280, improving the convenience of electrical connection.

[0042] Please refer to Figures 1, 3, and 4. The charging box 100 provided in this embodiment includes a base 10, a cover 20, and a limiting component 30. The base 10 has a bearing surface 103 for bearing the component to be charged. The cover 20 is connected to the base 10 and can be raised and lowered relative to the base 10 to switch between a pressed position and a released position. When the cover 20 is in the pressed position, the cover 20 presses the component to be charged against the bearing surface 103. The limiting component 30 is disposed on the cover 20 and / or the base 10, and the limiting component 30 is used to limit the lifting stroke of the cover 20 relative to the base 10.

[0043] The base 10 is a structure in the charging case 100 used to support the earphones 200. In some embodiments of this application, the rechargeable battery 110 and the circuit board 120 are both disposed in the base 10, which makes the base 10 heavier and reduces the possibility of the charging case 100 tipping over when the earphones 200 are stored in it. The base 10 is made of materials including but not limited to plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, the base 10 is made of plastic, which makes the charging case 100 lighter and easier for users to carry. In some embodiments, the bearing surface 103 may be the surface on the base 10 that abuts against the earphones 200 (the device to be charged). The bearing surface 103 may match the outer contour of the earphones 200, that is, the shape, size, and contour of the bearing surface 103 may be exactly the same or almost exactly the same as the shape, size, and contour of the side of the earphones 200 that abuts against the bearing surface 103. This facilitates the installation and positioning of the earphones 200 on the charging case 100, and also improves the stability of the earphones 200 stored in the charging case 100.

[0044] The cover 20 is a structure in the charging case 100 that can cooperate with the base 10 to confine the earphones 200. The cover 20 is made of materials including, but not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, the cover 20 is made of plastic, which makes the charging case 100 lighter and easier for users to carry. It is understood that the material of the cover 20 and the base 10 can be the same or different. The cover 20 can be raised and lowered relative to the base 10, which improves the usability of the charging case 100 and prevents the charging case 100 from being unable to charge the earphones 200 due to the large size of the bone conduction earphones.

[0045] In some embodiments, the charging case 100 may include a lifting assembly 40 disposed on the base 10 and / or the cover 20. The lifting assembly 40 is used to lift the cover 20 relative to the base 10 to switch between a pressed position and a released position. When the cover 20 is in the pressed position, the cover 20 presses the earphone 200; when the cover 20 is in the released position, the cover 20 releases the earphone 200.

[0046] The pressing position can be: along the lifting direction of the cover 20 (the same as the height direction (Z1 / Z2) of the charging case 100), the lifting component 40 allows the cover 20 to move downward relative to the base 10 (the cover 20 moves relative to the base 10 in the direction from the cover 20 to the base 10) to its limit; the releasing position can be: along the lifting direction of the cover 20, the lifting component 40 allows the cover 20 to move upward relative to the base 10 (the cover 20 moves relative to the base 10 in the direction from the base 10 to the cover 20) to its limit. It can be understood that in the normal state (e.g., when the charging case 100 does not contain the earphones 200), the cover 20 can be in the pressing position, thus reducing the space occupied by the charging case 100 and making it easier for the user to carry.

[0047] Specifically, in some embodiments, when the cover 20 is in the pressed position, it can press down on the earphone 200, thereby limiting the earphone 200 and preventing it from moving or shaking within the charging case 100, thus improving the stability of the earphone 200 stored in the charging case 100. Simultaneously, the pressed position of the cover 20 also prevents the earphone 200 from moving or shaking within the charging case 100, which could lead to poor contact between the charging terminal of the earphone 200 (i.e., the second electrical connector 280) and the charging terminal of the charging case 100 (i.e., the first electrical connector 17), thereby improving the stability of the charging of the earphone 200 by the charging case 100 and ensuring the normal operation of the charging function and / or signal transmission function. When the cover 20 is in the released position, the earphone 200 can be placed into the charging case 100; or, the earphone 200 can be removed from the charging case 100.

[0048] The limiting component 30 is a structure in the charging case 100 used to limit the lifting and lowering of the cover 20 relative to the base 10. In some embodiments of this application, the limiting component 30 can limit the downward movement of the cover 20 relative to the base 10, so that the farthest position that the cover 20 can move relative to the base 10 in the direction from the cover 20 to the base 10 is the pressing position; the limiting component 30 can also limit the upward movement of the cover 20 relative to the base 10, so that the farthest position that the cover 20 can move relative to the base 10 in the direction from the base 10 to the cover 20 is the releasing position.

[0049] In the charging case 100 of this application embodiment, the limiting component 30 can limit the lifting stroke of the cover 20 relative to the base 10. This can prevent the cover 20 from generating excessive impact force on the base 10 or excessive pressure force on the earphone 200 when the user applies too much force to the charging case 100, thereby reducing the possibility of damage to the charging case 100 and / or the earphone 200 and extending the service life of the charging case 100 and the earphone 200.

[0050] In addition, the limiting component 30 can prevent the cover 20 from falling off the base 10 due to excessive upward travel of the cover 20 relative to the base 10, thereby ensuring the stability and reliability of the charging case 100.

[0051] The charging case 100 will be further explained below with reference to the accompanying drawings.

[0052] Please refer to Figures 1, 3 and 4. In some embodiments, the cover 20 includes a main body 21 and an extension 23. The extension 23 extends from the main body 21 toward the base 10. The base 10 includes a seat 11 and a connector 13. The connector 13 extends from the seat 11 toward the cover 20. The extension 23 partially extends into the connector 13 and is able to move up and down relative to the connector 13 to selectively release or press the earphone 200.

[0053] Specifically, in some embodiments, the connector 13 may be provided with a movable space, and the extension 23 extends into the movable space and can move relative to the connector 13 within the movable space. The movable space can guide and limit the lifting and lowering of the extension 23, preventing the extension 23 from deviating and getting stuck during the lifting and lowering process, thereby improving the stability of the cover 20 lifting and lowering relative to the base 10.

[0054] In some embodiments, the main body 21 and the extension 23 are an integral structure, that is, the main body 21 and the extension 23 can be integrally molded to form a whole, which can improve the stability of the connection between the main body 21 and the extension 23. In other embodiments, the main body 21 and the extension 23 are separate structures, that is, the main body 21 and the extension 23 are two different structures. In one example, the main body 21 and the extension 23 can be joined together by a detachable connection method, including but not limited to snap-fit ​​connections or bolt connections. In another example, the main body 21 and the extension 23 can be joined together by a non-detachable connection method, including but not limited to adhesive or welding. It is understood that the connection method between the base 11 and the connector 13 is basically the same as the connection method between the main body 21 and the extension 23, and will not be described in detail here.

[0055] Furthermore, in some embodiments, both the rechargeable battery 110 and the circuit board 120 are disposed within the base 11. The base 11 includes a base body 111 and a top cover 113, with a connector 13 extending from the top cover 113 toward the cover body 20. The base body 111 and the top cover 113 are detachably connected, thereby facilitating the installation of the rechargeable battery 110 and the circuit board 120 within the base 11.

[0056] Referring to Figures 3 and 4, in some embodiments, the cover 20 and the base 10 together form an earphone compartment 101, which is used to house the earphones 200. It should be noted that in some embodiments, the first electrical connector 17 partially passes through the bearing surface 103 and extends into the earphone compartment 101. When the earphones 200 are supported on the bearing surface 103, that is, when the earphones 200 are housed in the earphone compartment 101, the first electrical connector 17 is electrically connected to the second electrical connector 280. In other words, when the earphones 200 are supported on the bearing surface 103, multiple first electrical connectors 17 and multiple second electrical connectors 280 are electrically connected one-to-one.

[0057] Specifically, in some embodiments, the main body 21, the extension 23, the connector 13, and the base 11 can collectively form the earphone compartment 101. When the cover 20 is raised relative to the base 10, the size of the earphone compartment 101 in the height direction (Z1 / Z2) of the charging case 100 increases, and the cover 20 changes from a pressed position to a released position. In this case, the earphone 200 can be placed into the earphone compartment 101; or, the earphone 200 can be removed from the earphone compartment 101. When the cover 20 is lowered relative to the base 10, the size of the earphone compartment 101 in the height direction (Z1 / Z2) of the charging case 100 decreases, and the cover 20 changes from a released position to a pressed position. In this case, the cover 20 can press the earphone 200 into the earphone compartment 101, and the charging case 100 can charge the earphone 200.

[0058] In some embodiments, the earphone case 101 includes a first side 1011, a second side 1013, a third side 1015, and a fourth side 1017 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 earphone case is open to allow the earphone 200 to be inserted into the earphone case 101.

[0059] Specifically, in some embodiments, in the direction perpendicular to the height (Z1 / Z2) of the charging case 100, the earphone compartment 101 includes a first side 1011, a second side 1013, a third side 1015, and a fourth side 1017 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 earphone compartment is open. Thus, when the cover 20 is raised relative to the base 10, the earphones 200 can be placed into the earphone compartment 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), thereby enabling the charging case 100 to charge and store the earphones 200.

[0060] In some embodiments of this application, the first side 1011 of the earphone compartment is closed, while the second side 1013, the third side 1015, and the fourth side 1017 of the earphone compartment are open. In this case, when the cover 20 rises relative to the base 10, the earphone 200 can be inserted into the earphone compartment 101 through the second side 1013 along the direction from the second side 1013 to the fourth side 1017 of the earphone compartment; or, the earphone 200 can be inserted into the earphone compartment 101 through the third side 1015 along the direction from the third side 1015 to the first side 1011 of the earphone compartment.

[0061] In some embodiments, the extension 23 is disposed on the side edge of the main body 21, and the connector 13 is disposed on the side edge of the base 11. Therefore, compared to a position where the extension 23 is disposed on the main body 21 away from the side edge (such as the center of the main body 21), and the connector 13 is disposed on a position on the base 11 away from the side edge (such as the center of the base 11), the earphone case 101 is larger, thereby facilitating the installation of the earphones 200 on the charging case 100 and improving the applicability of the charging case 100.

[0062] Please refer to Figure 4. In some embodiments, the limiting component 30 includes a limiting member and a locking member 33. One of the limiting member and the locking 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 locking member 33 cooperate to limit the upward and downward stroke of the cover 20 relative to the base 10.

[0063] It should be noted that in some embodiments, one of the limiting member and the locking 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 locking member 33 is disposed on the inner wall 131 of the connector 13 and the other is disposed on the outer wall of the extension member 23.

[0064] Specifically, in some embodiments, the limiting member and the locking member 33 cooperate to limit the upward movement 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 cover 20 from falling off the base 10 due to excessive upward movement, thereby ensuring the stability and reliability of the charging box 100. The limiting member and the locking member 33 cooperate to limit the downward movement of the cover 20 relative to the base 10, so that the farthest position that the cover 20 can move downward relative to the base 10 is the pressing position, preventing the cover 20 from continuing to descend under the force generated by the collision of the charging box 100 when the charging box 100 is dropped, which would cause the cover 20 to generate excessive 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.

[0065] In some embodiments, the limiting member is disposed on the inner wall of the base 10, and the locking member 33 is disposed on the outer wall of the cover 20. Specifically, the limiting member is disposed on the connector 13, and the locking member 33 is disposed on the extension 23.

[0066] Furthermore, in some embodiments, when the limiting member is disposed on the inner wall of the base 10 and the locking member 33 is disposed on the outer wall of the cover 20, the limiting member and the base 10 are an integral structure or a separate structure, and the locking member 33 and the cover 20 are an integral structure or a separate structure.

[0067] Specifically, the limiting component and the base 10 are an integral structure, meaning the limiting component and the connecting component 13 can be integrally molded to form a whole. This improves the connection strength between the limiting component and the connecting component 13, preventing the limiting component from detaching from the connecting component 13 when it engages with the locking component 33, thus ensuring the stability and reliability of the limiting component 30 during operation. Alternatively, the limiting component and the base 10 can be separate structures, meaning the limiting component and the connecting component 13 are two different structures, and they can be connected using either a detachable or non-detachable connection method. Detachable connection methods include, but are not limited to, snap-fit ​​connections or bolt connections; non-detachable connection methods include, but are not limited to, bonding or welding.

[0068] It is understandable that the connection and engagement method between the locking component 33 and the cover 20 is basically the same as the connection and engagement method between the limiting component and the base 10, and will not be described again here.

[0069] In other embodiments, the limiting member is disposed on the outer wall of the cover 20, and the locking member 33 is disposed on the inner wall of the base 10. Specifically, the limiting member is disposed on the extension 23, and the locking member 33 is disposed on the connector 13.

[0070] Furthermore, in some embodiments, when the locking 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 locking member 33 and the base 10 are an integral structure or a separate structure, and the limiting member and the cover 20 are an integral structure or a separate structure.

[0071] Specifically, the limiting member and the cover 20 are an integral structure, meaning the limiting member and the extension 23 can be integrally molded to form a whole. This improves the connection strength between the limiting member and the extension 23, preventing the limiting member from detaching from the extension 23 when it engages with the locking member 33, thus ensuring the stability and reliability of the limiting assembly 30. Alternatively, the limiting member and the cover 20 can be separate structures, meaning the limiting member and the extension 23 are two different structures, and they can be connected using either a detachable or non-detachable connection method. Detachable connection methods include, but are not limited to, snap-fit ​​connections or bolt connections; non-detachable connection methods include, but are not limited to, bonding or welding.

[0072] It is understandable that the connection and engagement method between the locking component 33 and the base 10 is basically the same as the connection and engagement method between the limiting component and the cover 20, and will not be described again here.

[0073] In the embodiments described below, only the example of the limiting member being disposed on the outer wall of the cover 20 and the locking member 33 being disposed on the inner wall of the base 10 is used for illustration.

[0074] In some embodiments, the limiting member may include two, and correspondingly, the locking member 33 also includes two; the two limiting members are respectively disposed on opposite sides of the extension member 23 in the height direction (Z1 / Z2) perpendicular to the charging box 100; the two locking members 33 are both disposed on the connector 13 and respectively cooperate with the two limiting members. Thus, compared to having only one limiting member, the setting of two limiting members can improve the stability of the cooperation between the limiting member and the locking member 33, and avoid the problem that the cover 20 is only subjected to force on one side (limited on one side) during the lifting and lowering process relative to the base 10, which would cause the cover 20 to tilt relative to the base 10. This ensures that the limiting component 30 can effectively limit the lifting and lowering stroke of the cover 20 relative to the base 10, and improve the stability and reliability of the charging box 100.

[0075] Please refer to Figures 4 and 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 spaced apart along the lifting direction of the cover 20. The first limiting member 311 is closer to the bottom of the base 10 than the second limiting member 313. The locking member 33 is located between the first limiting member 311 and the second limiting member 313.

[0076] 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 spaced apart along the lifting direction of the cover 20. The first limiting member 311 is closer to the bottom of the base 10 than the second limiting member 313. The locking member 33 is located between the first limiting member 311 and the second limiting member 313.

[0077] Specifically, in some embodiments, the outer wall of the extension member 23 is provided with two protrusions, both of which extend from the outer wall of the extension member 23 in a direction away from the center of the extension member 23, and the two protrusions are spaced apart along the lifting direction of the cover 20. The two protrusions are respectively formed as the first limiting member 311 and the second limiting member 313. The inner wall 131 of the connector 13 is provided with a protrusion, which extends from the inner wall 131 of the connector 13 towards the center of the connector 13, and the protrusion is formed as the locking member 33. When the charging box 100 is assembled, the protrusion can extend into the gap between the two protrusions, that is, the locking member 33 is located between the first limiting member 311 and the second limiting member 313. In this way, both the first limiting member 311 and the second limiting member 313 can cooperate with the locking member 33 to limit the upward and downward strokes of the cover 20 relative to the base 10.

[0078] In other embodiments, the outer wall of the extension member 23 is provided with a groove, which is recessed from the outer wall of the extension member 23 toward the center of the extension member 23. The two side walls of the groove in the lifting direction of the cover 20 are respectively formed as a first limiting member 311 and a second limiting member 313. The inner wall 131 of the connector 13 is provided with a protrusion, which protrudes from the inner wall 131 of the connector 13 toward the center of the connector 13 and forms a locking member 33. When the charging box 100 is assembled, the protrusion can extend into the groove, that is, the locking member 33 is located between the first limiting member 311 and the second limiting member 313. In this way, both the first limiting member 311 and the second limiting member 313 can cooperate with the locking member 33 to limit the rising and falling strokes of the cover 20 relative to the base 10.

[0079] Referring to Figure 5, in one example, a groove is provided on the outer wall of the extension 23, and the two side walls of the groove in the lifting direction of the cover 20 are respectively formed as the first limiting member 311 and the second limiting member 313. The groove is provided with a guide protrusion 315 extending in the lifting direction of the cover 20, and the protrusion is provided with a guide groove 331. The guide protrusion 315 cooperates with the guide groove 331 to guide and limit the lifting of the cover 20 relative to the base 10, prevent the cover 20 from deviating and getting stuck during the lifting process relative to the base 10, thereby improving the stability of the lifting of the cover 20 relative to the base 10 and ensuring the normal operation of the charging box 100.

[0080] 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, while the other of the first limiting member 311 and the second limiting member 313 is a separate structure with the extension member 23. This can reduce the number of parts in the charging box 100 and improve the assembly efficiency of the charging box 100.

[0081] In some embodiments, when the first limiting member 311 cooperates with the locking member 33, the limiting component 30 is used to limit the upward stroke of the cover 20 relative to the base 10; when the second limiting member 313 cooperates with the locking member 33, the limiting component 30 is used to limit the downward stroke of the cover 20 relative to the base 10.

[0082] Specifically, in some embodiments, when the cover 20 moves in the upward direction relative to the base 10 until the first limiting member 311 engages with the locking member 33, the limiting component 30 can limit the upward stroke of the cover 20 relative to the base 10, that is, the cover 20 cannot continue to rise relative to the base 10; when the cover 20 moves in the downward direction relative to the base 10 until the second limiting member 313 engages with the locking member 33, the limiting component 30 can limit the downward stroke of the cover 20 relative to the base 10, that is, the cover 20 cannot continue to descend relative to the base 10.

[0083] More specifically, in some embodiments, when the cover 20 is in the released position, the locking member 33 abuts against the first limiting member 311, in which case the cover 20 can release the earphone 200, that is, the earphone 200 can be taken out from the earphone compartment 101; when the cover 20 is in the pressed position, the locking member 33 abuts against the second limiting member 313, in which case the cover 20 can press the earphone 200, that is, the earphone 200 can be pressed into the earphone compartment 101.

[0084] Please refer to Figures 4 and 5. In some embodiments, the limiting component 30 further includes a shock absorber 105. The shock absorber 105 is disposed on the first limiting member 311 and / or the locking member 33, and when the cover 20 is in the released position, the shock absorber 105 is located between the first limiting member 311 and the locking member 33.

[0085] The shock absorber 105 prevents damage caused by rigid collision between the first limiting member 311 and the locking member 33 when they come into contact, thereby extending the service life of the limiting assembly 30 and ensuring the stability and reliability of the charging box 100. It should be noted that in some embodiments, the shock absorber 105 is made of at least one of silicone, rubber, resin, and polyurethane.

[0086] In some embodiments, the shock absorber 105 is disposed on the side of the first limiting member 311 opposite to the locking member 33. In other embodiments, the shock absorber 105 is disposed on the side of the locking member 33 opposite to the first limiting member 311. In still other embodiments, two shock absorbers 105 are included, with the two shock absorbers 105 respectively disposed on the side of the first limiting member 311 opposite to the locking member 33 and on the side of the locking member 33 opposite to the first limiting member 311.

[0087] In some embodiments, the shock absorber 105 and the first limiting member 311 can be detachably connected. The detachable connection includes, but is not limited to, snap-fit ​​connections or threaded connections. In other embodiments, the shock absorber 105 and the first limiting member 311 can be non-detachably connected. The non-detachable connection includes, but is not limited to, adhesive bonding. It is understood that the connection method between the shock absorber 105 and the locking 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 again here.

[0088] In some embodiments, the shock absorber 105 is disposed on the second limiting member 313 and / or the locking 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 locking member 33. The shock absorber 105 prevents rigid collisions between the second limiting member 313 and the locking member 33 when they come into contact, thus extending the service life of the limiting assembly 30 and ensuring the stability and reliability of the charging box 100.

[0089] In some embodiments, the shock absorber 105 is disposed on the side of the second limiting member 313 opposite to the locking member 33. In other embodiments, the shock absorber 105 is disposed on the side of the locking member 33 opposite to the second limiting member 313. In still other embodiments, the shock absorber 105 includes two shock absorbers 105, each disposed on the side of the second limiting member 313 opposite to the locking member 33, and on the side of the locking member 33 opposite to the second limiting member 313, respectively.

[0090] It is understandable 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 again here.

[0091] Please refer to Figures 1 and 3. In some embodiments, the charging box 100 further includes a fastener 106, which is disposed on the base 10 and / or the cover 20, and is used to fix the component to be charged to the bearing surface 103.

[0092] Referring to Figure 2, the fastener 106 is a structure in the charging case 100 used to secure the earphone 200. In some embodiments of this application, the earphone 200 is provided with a mating part 270, and the fastener 106 cooperates with the mating part 270 to secure the earphone 200. Specifically, when the earphone 200 is placed in the charging case 100, the fastener 106 can cooperate with the mating part 270 to secure the earphone 200. This prevents the earphone 200 from moving or shaking in the charging case 100, which could lead to 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). This improves the stability of the charging of the earphone 200 by the charging case 100 and ensures the normal operation of the charging function and / or signal transmission function.

[0093] It should be noted that, in some embodiments, the engagement method of the fastener 106 and the mating part 270 includes, but is not limited to, snap-fit ​​engagement and magnetic engagement. In one example, when the engagement method of the fastener 106 and the mating part 270 is magnetic engagement, one of the fastener 106 and the mating part 270 is a first magnetic material, and the other is a second magnetic material or ferrous component that is attracted to the first magnetic material.

[0094] In some embodiments, the fastener 106 is a magnetic component, and the mating component 270 is a magnetic attractant, with the magnetic poles of the magnetic component and the magnetic attractant having opposite poles. This ensures the stability of the mating of the magnetic component and the magnetic attractant, thereby preventing the earphone 200 from moving or shaking within the charging case 100, which could lead to poor contact between the second electrical connector 280 and the first electrical connector 17, thus improving the stability of the charging case 100 in charging the earphone 200. Exemplarily, both the magnetic component and the magnetic attractant can be magnets, and when the earphone 200 is positioned in the contoured groove, the S pole of the magnetic component is opposite to the N pole of the magnetic attractant.

[0095] In some embodiments, the cover 20 and / or the base 10 are provided with a contoured groove 1019, which is used to limit the earphone 200 and matches the outer contour of the earphone 200. A fastener 106 is provided on the base 10 and / or the cover 20, and the fastener 106 is used to fix the earphone 200 to the contoured groove 1019. It should be noted that in some embodiments, the bearing surface 103 may be the bottom wall of the contoured groove 1019.

[0096] The contoured groove 1019 is a recess or cavity manufactured according to a specific shape (such as the outer contour of the earphone 200). In some embodiments of this application, the contoured groove 1019 matches the outer contour of the earphone 200; that is, the shape, size, and contour of the contoured groove 1019 are exactly the same or almost exactly the same as the shape, size, and contour of the earphone 200. The contoured groove 1019 facilitates the installation and positioning of the earphone 200 on the charging case 100 and limits the installation of the earphone 200 on the charging case 100, thereby improving the stability of the earphone 200 stored in the charging case 100.

[0097] In some embodiments, when the earphone 200 includes a battery compartment 220, the contoured 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 contoured groove 1019 are exactly the same or almost exactly the same as the shape, size, and contour of the battery compartment 220, which can improve the stability of the battery compartment 220 stored in the charging case 100. It is understood that the second electrical connector 280 is disposed in the battery compartment 220 and electrically connected to the battery in the battery compartment 220.

[0098] In some embodiments, the base 10 is provided with a contoured groove 1019. In other embodiments, the cover 20 is provided with a contoured groove 1019. In still other embodiments, both the base 10 and the cover 20 are provided with contoured grooves 1019. The contoured grooves 1019 on both the base 10 and the cover 20 match the outer contour of the earphone 200. It is understood that the orthographic projection of the contoured groove 1019 on the cover 20 onto the base 10 at least partially overlaps with the contoured groove 1019 on the base 10. The shape, size, and contour of the contoured groove 1019 on the base 10 and the contoured groove 1019 on the cover 20 may be the same or different.

[0099] Referring to Figure 6, in some embodiments, the cover 20 further includes a first protrusion 25, which extends from the main body 21 toward the base 10 and participates in forming the earphone compartment 101.

[0100] Specifically, in some embodiments, when the cover 20 presses against 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 coming off the charging case 100, and ensuring the stability of the charging case 100 in charging and housing the earphone 200.

[0101] More specifically, in some embodiments, when the cover 20 includes a first protrusion 25, the first protrusion 25 and the extension 23 are respectively disposed on opposite sides of the main body 21. In this way, when the cover 20 presses against the earphone 200, the first protrusion 25 and the extension 23 can jointly limit the earphone 200, reducing the possibility of the earphone 200 detaching from the charging case 100.

[0102] In some embodiments, the base 10 further includes a second protrusion 15 extending from the base 11 toward the cover 20, the second protrusion 15 contributing to the formation of the earphone compartment 101.

[0103] Specifically, in some embodiments, when the cover 20 presses against 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 in charging and housing the earphone 200.

[0104] More specifically, in some embodiments, when the base 10 includes a second protrusion 15, the second protrusion 15 and the connector 13 are respectively disposed on opposite sides of the base 11. In this way, when the cover 20 presses the earphone 200, the second protrusion 15 and the connector 13 can jointly limit the earphone 200, reducing the possibility of the earphone 200 detaching from the charging case 100.

[0105] In some embodiments, a buffer 107 is provided on the side of the cover 20 facing the base 10, and the buffer 107 is located between the device to be charged and the cover 20 when the device to be charged is supported on the support surface 103.

[0106] The buffer 107 prevents damage caused by rigid collision between the cover 20 and the earphone 200 when the cover 20 presses against the earphone 200, thereby extending the service life of the earphone 200 and the charging case 100 and ensuring their normal operation. It should be noted that in some embodiments, the buffer 107 is made of materials including, but not limited to, silicone, rubber, and resin.

[0107] Specifically, in some embodiments, when the earphone 200 is supported on the support surface 103, the buffer 107 is located between the earphone 200 and the cover 20; that is, the buffer 107 is disposed on the cover 20 and located in the earphone compartment 101. In one example, the shape, size, and contour of the buffer 107 match the shape, size, and contour of the earphone 200. In another example, when the cover 20 presses against the earphone 200, the buffer 107 can undergo elastic deformation, and the shape, size, and contour of the deformed buffer 107 still match the shape, size, and contour of the earphone 200.

[0108] In some embodiments, a buffer 107 is provided on the side of the base 10 facing the cover 20, and the buffer 107 is located between the charging component and the base 10 when the component to be charged is supported on the bearing surface 103.

[0109] The buffer 107 prevents damage caused by rigid collision between the base 10 and the earphone 200 when the earphone 200 is placed in the earphone case 101, thereby extending the service life of the earphone 200 and the charging case 100 and ensuring their normal operation. It should be noted that in some embodiments, the buffer 107 is made of materials including, but not limited to, silicone, rubber, and resin.

[0110] Specifically, in some embodiments, when the earphone 200 is supported on the support surface 103, the buffer 107 is located between the earphone 200 and the base 10; that is, the buffer 107 is disposed on the base 10 and located in the earphone compartment 101. In one example, the shape, size, and contour of the buffer 107 match the shape, size, and contour of the earphone 200. In another example, when the cover 20 presses against the earphone 200, the buffer 107 can undergo elastic deformation, and the shape, size, and contour of the deformed buffer 107 still match the shape, size, and contour of the earphone 200.

[0111] In related technologies, the charging case includes a metal pillar that guides the movement of the cover relative to the base. However, due to limitations in the size of the metal pillar, the cover is prone to loosening or wobbling during movement relative to the base, affecting the stability of the charging case's opening and closing.

[0112] Therefore, referring to Figures 3 and 7, in some embodiments of this application, the lifting assembly 40 includes a first guide 41 and a second guide 43. The first guide 41 is disposed on the side wall 231 of the extension 23 of the cover 20, and the second guide 43 is disposed on the inner wall 131 of the connector 13 of the base 10. The first guide 41 and the second guide 43 cooperate to restrict the movement of the cover 20 relative to the base 10 in the horizontal direction, which is perpendicular to the lifting direction of the cover 20. Therefore, the arrangement of the first guide 41 and the second guide 43 can, on the one hand, restrict the horizontal movement of the cover 20 relative to the base 10, that is, prevent the cover 20 from moving horizontally relative to the base 10. Thus, compared with the charging box 100 in the related art that includes a metal column, the arrangement of the first guide 41 and the second guide 43 can prevent the cover 20 from loosening or shaking during the movement of the base 10, thereby improving the stability of the opening and closing of the charging box 100. On the other hand, it can provide guidance for the lifting and lowering movement of the cover 20 relative to the base 10, thereby also improving the stability of the opening and closing of the charging box 100.

[0113] In addition, compared with the metal pillars in related technologies that guide the movement of the cover 20 relative to the base 10, the charging box 100 in this embodiment has a lower production cost, which helps to improve product competitiveness.

[0114] In some embodiments, one of the first guide member 41 and the second guide member 43 is a protrusion, and the other is a groove. In one example, the first guide member 41 is a protrusion, and the second guide member 43 is a groove. In another example, the first guide member 41 is a groove, and the second guide member 43 is a protrusion.

[0115] In the case where the first guide 41 is a groove and the second guide 43 is a protrusion, the first guide 41 can be recessed from the side wall 231 of the extension 23 toward the center of the extension 23; the second guide 43 can protrude from the inner wall 131 of the connector 13 toward the center of the connector 13. When the extension 23 extends into the connector 13, the second guide 43 can extend into the first guide 41 to guide the lifting and lowering of the extension 23 relative to the connector 13.

[0116] In other embodiments, one of the first guide member 41 and the second guide member 43 is a slider, and the other is a slide rail. In one example, the first guide member 41 is a slider, and the second guide member 43 is a slide rail. In another example, the first guide member 41 is a slide rail, and the second guide member 43 is a slider.

[0117] In some embodiments, the first guide member 41 and the extension member 23 are an integral structure. That is, the first guide member 41 and the extension member 23 can be integrally molded to form a whole, which can improve the stability of the connection between the first guide member 41 and the extension member 23. Furthermore, compared with the charging box 100 including metal pillars in related technologies, the integral structure of the first guide member 41 and the extension member 23 can also reduce the assembly steps of the charging box 100, thereby improving the assembly efficiency of the charging box 100.

[0118] It is understood that in other embodiments, the first guide member 41 and the extension member 23 may be separate structures, that is, the first guide member 41 and the extension member 23 are two different structures. The first guide member 41 and the extension member 23 may be connected together by a detachable connection method or a non-detachable connection method. Among them, the detachable connection method includes, but is not limited to, snap-fit ​​connection or bolt connection; the non-detachable connection method includes, but is not limited to, adhesive or welding.

[0119] In some embodiments, the second guide 43 and the connector 13 are integrally formed. That is, the second guide 43 and the connector 13 can be integrally molded to form a whole, which can improve the stability of the connection between the second guide 43 and the connector 13. Furthermore, compared with the charging box 100 including metal pillars in related technologies, the integral structure of the second guide 43 and the connector 13 can also reduce the assembly steps of the charging box 100, thereby improving the assembly efficiency of the charging box 100.

[0120] It is understood that in other embodiments, the second guide 43 and the connector 13 may be separate structures, that is, the second guide 43 and the connector 13 are two different structures. The second guide 43 and the connector 13 may be combined using a detachable connection method or a non-detachable connection method. The detachable connection method includes, but is not limited to, snap-fit ​​connection or bolt connection; the non-detachable connection method includes, but is not limited to, bonding or welding.

[0121] In some embodiments, the extension 23 includes a first side 2311, a second side 2313, a third side 2315 and a fourth side 2317 connected in sequence, and a first guide 41 is disposed on at least one of the first side 2311, the second side 2313, the third side 2315 and the fourth side 2317 of the extension.

[0122] For example, the first guide member 41 can be disposed on opposite sides of the extension member 23. For instance, 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. This ensures the balance of the cover 20 during movement relative to the base 10, thereby improving the stability of the opening and closing of the charging case 100. Wherein, 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.

[0123] In some embodiments, at least one first guide 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, at least one first guide member 41 is provided on the same side of the extension member 23 (e.g., the first side 2311, the second side 2313, the third side 2315, or the fourth side 2317 of the extension member), which can prevent the extension member 23 from deflecting or shaking in the connector 13 during the movement of the cover 20 relative to the base 10, thereby further improving the stability of the cover 20 when moving relative to the base 10.

[0124] In related technologies, the base 10 and the cover 20 are usually joined together by magnetic attraction. However, the magnetic attraction is easily affected by external factors. For example, when the magnetic attraction decreases due to external factors, the cover 20 may be accidentally opened under slight external force or vibration, affecting the stability of the earphones 200; or, when the magnetic attraction increases due to external factors, the cover 20 may be difficult to open, affecting the taking and putting away of the earphones 200.

[0125] Referring to Figures 3, 6, and 7, in some embodiments of this application, the charging case 100 further includes a button structure 60. The button structure 60 includes a locking member 61, a mating member 63, and a resetting member 65. The locking member 61 reciprocates between a locked position and a first unlocked position along a first direction (Z1 / Z2), and is used to connect one of the base 10 and the cover 20. The mating member 63 reciprocates between a locked position and a second unlocked position along a second direction (X1 / X2), and is used to connect the other of the base 10 and the cover 20. The resetting member 65 is connected between the mating member 63 and the base 10 or the cover 20, and is used to hold the mating member 63 in the locked position. The first direction (Z1 / Z2) and the second direction (X1 / X2) intersect; when the locking member 61 and the mating member 63 are in the locked position, they engage in a locking mechanism. 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 box 100.

[0126] In some embodiments, the engaging member 61 is connected to the cover 20, the mating member 63 is connected to the base 10, and the resetting member 65 is connected between the mating member 63 and the base 10. In other embodiments, the engaging member 61 is connected to the base 10, the mating member 63 is connected to the cover 20, and the resetting member 65 is connected between the mating member 63 and the cover 20. This application only describes an example where the engaging member 61 is connected to the cover 20, the mating member 63 is connected to the base 10, and the resetting member 65 is connected between the mating member 63 and the base 10.

[0127] 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 engaged, and in this case, the cover 20 can press the earphone 200. In other words, when the cover 20 is in the pressed position, the engaging member 61 and the mating member 63 are in the locked position. When the engaging member 61 is in the first unlocked position and the mating member 63 is in the second unlocked position, the engaging member 61 and the mating member 63 are disengaged, and in this case, the cover 20 can release the earphone 200. In other words, when the cover 20 is in the released position, the engaging member 61 is in the first unlocked position and the mating member 63 is in the second unlocked position. The first direction (Z1 / Z2) is the lifting direction of the cover 20.

[0128] It is understood that in some embodiments, the reciprocating movement of the mating member 63 along the second direction (X1 / X2) between the locked position and the second unlocked position requires manual intervention. That is, the mating member 63 is manually switched between the locked position and the second unlocked position along the second direction (X1 / X2); or, the mating member 63 is manually switched between the locked position and the second unlocked position along the second direction (X1 / X2) with the aid of a tool. For example, when the user applies force to the mating member 63, the mating member 63 can move relative to the base 10 along the second direction (X1 / X2) from the locked position to the second unlocked position; when the user does not apply force to the mating member 63, the mating member 63 can move along the second direction (X1 / X2) from the second unlocked position to the locked position under the action of the reset member 65. When the mating part 63 moves along the second direction (X1 / X2), the base 10 will not move along the second direction (X1 / X2) with the mating part 63. In other words, the mating part 63 can move relative to the base 10 along the second direction (X1 / X2).

[0129] The reciprocating movement of the engaging component 61 along the first direction (Z1 / Z2) between the locked position and the first unlocked position requires manual intervention. Specifically, the engaging component 61 is manually switched between the locked and unlocked positions along the first direction (Z1 / Z2); or, a tool is used to manually switch the engaging component 61 between the locked and unlocked positions along the first direction (Z1 / Z2). For example, when the user applies force to the engaging component 61, the engaging component 61 can move from the first unlocked position to the locked position along the first direction (Z1 / Z2); when the user does not apply force to the engaging component 61 and the mating component 63 is in the second unlocked position, the engaging component 61 can move from the locked position to the first unlocked position along the first direction (Z1 / Z2). When the engaging component 61 moves along the first direction (Z1 / Z2), the cover 20 moves along the first direction (Z1 / Z2) along with the engaging component 61.

[0130] 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 15°, 30°, 45°, 60°, 75°, 100°, 115°, 120°, or 135°, etc. In this application embodiment, only the example of the first direction (Z1 / Z2) and the second direction (X1 / X2) being perpendicular is used for illustration.

[0131] In summary, the engaging component 61 reciprocates between the locked position and the first unlocked position along the first direction (Z1 / Z2), connecting one of the base 10 and the cover 20. The mating component 63 reciprocates between the locked position and the second unlocked position along the second direction (X1 / X2), connecting the other of the base 10 and the cover 20. When the engaging component 61 and the mating component 63 are in the locked position, they engage and cooperate. Therefore, compared with the charging case 100 in related technologies, the button structure 60 can prevent the relative movement between the cover 20 and the base 10 from becoming unstable due to changes in magnetic attraction, thereby improving the stability of the charging case 100.

[0132] Referring to Figures 3, 6, and 7, in some embodiments, the button structure 60 further includes an elastic element 67 connected between the base 10 and the cover 20, extending along a first direction (Z1 / Z2). A reset element 65 is connected between the mating element 63 and the base 10, extending along a second direction (X1 / X2). When the cover 20 is in the pressed position, the elastic element 67 has a first length, and the reset element 65 is in a first state; when the cover 20 is in the released position, the elastic element 67 has a second length, and the reset element 65 is in a second state, the second length being greater than the first length.

[0133] Specifically, in some embodiments, since the size of the earphone compartment 101 in the height direction (Z1 / Z2) of the charging case 100 increases when the cover 20 switches from the pressed position to the released position, and the second length of the elastic member 67 when the cover 20 is in the released position is greater than the first length of the elastic member 67 when the cover 20 is in the pressed position, the elastic member 67 is in a compressed state when the cover 20 is in the pressed position; and the elastic member 67 is in a normal state (not stretched or compressed) or a compressed state (at which 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 pressed position). Thus, during the process of the cover 20 switching from the pressed position to the released position, the elastic member 67 can provide elastic force to the cover 20, thereby ensuring that the cover 20 can rise smoothly relative to the base 10.

[0134] In some embodiments, during the process of switching the cover 20 from the pressed position to the released position, the reset member 65 sequentially switches between a first state, a second state, and a first state. During the process of switching the cover 20 from the released position to the pressed position, the reset member 65 sequentially switches between a first state, a second state, and a first state. 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.

[0135] Specifically, in some embodiments, when the reset member 65 is in the first state, both the engaging member 61 and the mating member 63 are in the locked position; when the reset member 65 is in the second state, the engaging member 61 is in the first unlocked position and the mating member 63 is in the second unlocked position.

[0136] Specifically, when the cover 20 switches from the pressed position to the released position, the reset member 65 sequentially switches between a first state, a second state, and a third state; that is, the mating member 63 sequentially switches between a locked position, a second unlocked position, and a locked position. When the mating member 63 moves from the locked position to the second unlocked position, the mating member 63 and the engaging member 61 are released from their engaging position, and the engaging member 61 moves from the locked position to the first unlocked position. It is 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. Thus, the reset member 65 can generate a reset force on the mating member 63, which is used to keep the mating member 63 in the locked position.

[0137] Furthermore, in some embodiments, when the cover 20 is in the pressed position and the mating member 63 is subjected to a first force, the mating member 63 can move in the positive direction X1 along the second direction (X1 / X2), the reset member 65 switches from the first state to the second state, and the elastic member 67 extends and pushes the cover 20 to move in the upward direction of the cover 20; when the first force disappears, the reset member 65 switches from the second state to the first state, the mating member 63 moves in the opposite direction X2 along the second direction (X1 / X2) and is located below the engaging member 61.

[0138] Specifically, in some embodiments, when the mating member 63 is subjected to a first force and moves in the positive direction X1 of the second direction (X1 / X2), the reset member 65 generates a reset force, and the mating member 63 moves from the locked position to the second unlocked position to release the engagement between the mating member 63 and the engaging member 61. The elastic force of the elastic member 67 can push the cover 20 to move in the upward direction of the cover 20. When the first force disappears, the reset force of the reset member 65 can cause the mating member 63 to move in the opposite direction X2 of the second direction (X1 / X2), that is, the reset force can cause the mating member 63 to move from the second unlocked position to the locked position. In this case, the mating member 63 is located below the engaging member 61. Thus, when the mating member 63 is subjected to the first force, the cover 20 can switch from the pressed position to the released position.

[0139] In some embodiments, when the cover 20 is in the released position and the cover 20 is subjected to a second force, the elastic member 67 is compressed, the cover 20 moves in the descending direction of the cover 20, the engaging member 61 pushes the mating 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 locked position, the mating member 63 moves in the opposite direction X2 of the second direction (X1 / X2), and the reset member 65 switches from the second state to the first state.

[0140] Specifically, in some embodiments, when the cover 20 is subjected to a second force and moves along the downward direction of the cover 20 (the direction from the cover 20 to the base 10), the engaging member 61 exerts a pushing force on the mating member 63 to push the mating member 63 to move along the positive X1 direction of the second direction (X1 / X2). At this time, the resetting member 65 generates a resetting force, and the mating member 63 moves from the locked position to the second unlocked position. When the engaging member 61 moves to the locked position along the downward direction of the cover 20, the engaging member 61 does not exert a pushing force on the mating member 63, and the resetting force of the resetting member 65 can cause the mating member 63 to move in the opposite direction X2 of the second direction (X1 / X2). That is, the resetting force can cause the mating member 63 to move from the second unlocked position to the locked position. In this case, the engaging member 61 and the mating member 63 are engaged. Thus, when the cover 20 is subjected to the second force, the cover 20 can switch from the released position to the pressed position.

[0141] Please refer to Figures 3 to 7. In some embodiments, the first force on the mating member 63 is pressure. The length of the reset member 65 in the first state is greater than the length of the reset 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 negative direction X2 of the second direction (X1 / X2) is the direction towards the outside of the base 10.

[0142] Specifically, referring to Figures 6 and 7, 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. In this case, the reset member 65 can be a compression spring. When the reset member 65 is in the first state, the mating member 63 is in the locked position, and the reset member 65 is in the normal state (not stretched or compressed) or in the first compressed state. When the reset member 65 is in the second state, the mating member 63 is in the second unlocked position, and the reset member 65 is in the second compressed state. The length of the reset member 65 in the first compressed state is greater than the length of the reset member 65 in the second compressed state.

[0143] Please refer to Figures 3 and 9. In some embodiments, the first force on the mating member 63 is a tensile force, the length of the reset member 65 in the first state is less than the length of the reset 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 negative direction X2 of the second direction (X1 / X2) is the direction towards the inside of the base 10.

[0144] Specifically, referring to Figure 9, in some embodiments, when the engaging member 61 and the mating member 63 are engaged, the resetting member 65 is located on the side of the mating member 63 opposite to the engaging member 61. In this case, the resetting member 65 can be a tension spring. When the resetting member 65 is in the first state, the mating member 63 is in the locked position, and the resetting member 65 is in the normal state (not stretched or compressed) or in the first stretched state. When the resetting member 65 is in the second state, the mating member 63 is in the second unlocked position, and the resetting member 65 is in the second stretched state. The length of the resetting member 65 in the first stretched state is less than the length of the resetting member 65 in the second stretched state.

[0145] Please refer to Figures 3 to 7, and in conjunction with Figure 8 or 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 engages with the engaging portion 613 so that the mating member 63 and the engaging member 61 are engaged.

[0146] Specifically, in some embodiments, when both the engaging member 61 and the mating member 63 are in the locked position, the hook portion 633 engages with the engaging member 613; when the engaging member 61 is in the first unlocked position and the mating member 63 is in the second unlocked position, the hook portion 633 disengages from the engaging member 613.

[0147] 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 integrally formed into a whole, which can improve the stability of the connection between the mating body 631 and the hook portion 633, prevent the hook portion 633 from falling off the mating body 631 when it is engaged with the engaging portion 613, thereby ensuring the stability and reliability of the button structure 60 in operation.

[0148] In other embodiments, the mating body 631 and the hook portion 633 are separate structures, meaning they are two distinct structures. In one example, the mating body 631 and the hook portion 633 can be joined together in a detachable manner, including but not limited to snap-fit ​​connections or bolt connections. In another example, the mating body 631 and the hook portion 633 can be joined together in a non-detachable manner, including but not limited to adhesive bonding or welding. It is understood that the connection method between the engaging body 611 and the engaging portion 613 is essentially the same as that between the mating body 631 and the hook portion 633, and will not be elaborated upon here.

[0149] Furthermore, in some embodiments, the engaging portion 613 is provided with a first inclined surface 6131, and the hook portion 633 is provided with a second inclined surface 6331. During the process of the cover 20 switching from the release position to the pressing position, the first inclined surface 6131 and the second inclined surface 6331 abut against each other.

[0150] If the engaging portion 613 does not have a first inclined surface 6131 and the hook portion 633 does not have a second inclined surface 6331, then when the engaging portion 613 moves along the descending direction of the cover 20 to make the engaging portion 613 abut against the hook portion 633, the engaging portion 613 can only generate a pushing force on the hook portion 633 in the first direction (Z1 / Z2) (i.e., the lifting direction of the charging box 100), and this pushing force cannot push the hook portion 633 to move in the second direction (X1 / X2). Therefore, the provision of the first inclined surface 6131 and the second inclined surface 6331 allows the engaging portion 613 to generate a pushing force on the hook portion 633 when the first inclined surface 6131 and the second inclined surface 6331 abut against each other. The component of this pushing force in the second direction (X1 / X2) can push the hook portion 633 to move in the second direction (X1 / X2).

[0151] Specifically, in some embodiments, the angle between the first inclined plane 6131 and the positive X1 of the second direction (X1 / X2) is a first acute angle, and the angle between the second inclined plane 6331 and the positive X1 of the second direction (X1 / X2) is also a second acute angle. It should be noted that in some embodiments, the first acute angle and the second acute angle may be the same or different.

[0152] In some embodiments, the engaging portion 613 has a first plane 6133, and the hook portion 633 has a second plane 6333. When the cover 20 is in the pressed position, the first plane 6133 and the second plane 6333 abut against each other. Both the first plane 6133 and the second plane 6333 are perpendicular to the first direction (Z1 / Z2). Therefore, the abutment between the first plane 6133 and the second plane 6333 achieves a locking engagement between the engaging portion 613 and the mating portion 63, thereby restricting the lifting and lowering of the cover 20 relative to the base 10.

[0153] Referring to Figures 6 and 7, in some embodiments, the base 10 or the cover 20 is provided with a first guide 108. The first guide 108 extends along a first direction (Z1 / Z2) and cooperates with the elastic member 67 to guide the extension and retraction of the elastic member 67. The first guide 108 can restrict and guide the deformation of the elastic member 67, reducing or even preventing deformation of the elastic member 67 in directions other than the first direction (Z1 / Z2), ensuring that the elastic member 67 can provide effective elastic force to the cover 20, so that the cover 20 can switch from a pressed position to a released position. It should be noted that the number of first guides 108 and elastic members 67 is in a one-to-one correspondence, that is, one first guide 108 corresponds to one elastic member 67.

[0154] In some embodiments, the first guide member 108 is a column, and the elastic member 67 is sleeved on the side wall of the column.

[0155] Specifically, in one example, the outer contour of the column's sidewall is a continuous, uninterrupted closed ring. Exemplarily, the column can be cylindrical, in which case the outer contour of the column's sidewall is circular. In another example, the outer contour of the column's sidewall is a non-closed ring with at least one discontinuity. Thus, when the elastic member 67 is fitted onto the sidewall of the column, the contact area between the elastic member 67 and the sidewall of the column is small, thereby reducing the frictional force between the elastic member 67 and the column, ensuring the stability of the elastic member 67's expansion and contraction along the first direction (Z1 / Z2). Exemplarily, the column is provided with at least one groove, which is recessed from the outer side of the column's sidewall toward the center of the column.

[0156] In other embodiments, the first guide member 108 is a column with a receiving space inside, and the elastic member 67 is received in the receiving space.

[0157] Specifically, in one example, the inner contour of the sidewall of the column is a continuous, uninterrupted closed ring. Exemplarily, the accommodating space can be cylindrical, in which case the inner contour of the sidewall of the column is circular. In another example, the inner contour of the sidewall of the column is a non-closed ring with at least one discontinuity. Thus, when the elastic member 67 is accommodated within the accommodating space, the contact area between the elastic member 67 and the sidewall of the column is small, thereby reducing the frictional force between the elastic member 67 and the column, ensuring the stability of the elastic member 67's expansion and contraction along the first direction (Z1 / Z2).

[0158] In some embodiments, the base 10 or the mating member 63 is provided with a second guide 109. The second guide 109 extends along a second direction (X1 / X2) and engages with the reset member 65 to guide the extension and retraction of the reset member 65. The second guide 109 provides restriction and guidance for the deformation of the reset member 65, reducing or even preventing deformation of the reset member 65 in directions other than the second direction (X1 / X2), ensuring that the reset member 65 can provide an effective reset force to the mating member 63, so that the mating member 63 remains in the locked position. It should be noted that the number of second guides 109 and reset members 65 is in a one-to-one correspondence; that is, one second guide 109 corresponds to one reset member 65.

[0159] In some embodiments, the second guide member 109 is a column, and the reset member 65 is sleeved on the side wall of the column.

[0160] Specifically, in one example, the outer contour of the sidewall of the column is a continuous, uninterrupted closed ring. For example, the column may be cylindrical, in which case the outer contour of the sidewall is circular. In another example, the outer contour of the sidewall of the column is a non-closed ring with at least one discontinuity. Thus, when the reset member 65 is fitted onto the sidewall of the column, the contact area between the reset member 65 and the sidewall of the column is small, thereby reducing the friction between the reset member 65 and the column and ensuring the stability of the reset member 65's extension and retraction along the second direction (X1 / X2).

[0161] In other embodiments, the second guide member 109 is a column with a receiving space inside, and the reset member 65 is received in the receiving space.

[0162] Specifically, in one example, the inner contour of the sidewall of the column is a continuous, uninterrupted closed ring. Exemplarily, the accommodating space can be cylindrical, in which case the inner contour of the sidewall of the column is circular. In another example, the inner contour of the sidewall of the column is a non-closed ring with at least one discontinuity. Thus, when the elastic member 67 is accommodated within the accommodating space, the contact area between the elastic member 67 and the sidewall of the column is small, thereby reducing the frictional force between the elastic member 67 and the column, ensuring the stability of the elastic member 67's expansion and contraction along the first direction (Z1 / Z2).

[0163] Please refer to Figures 6 and 7. In some embodiments, the base 10 is provided with a blocking member 51 and a support member 53. One end of the resetting member 65 is connected to the blocking member 51, and the other end is connected to the mating member 63. The mating member 63 is supported on the support member 53 and can move along the second direction (X1 / X2) on the support member 53.

[0164] 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, and the blocking body 511 is spaced apart from the side wall of the base 10 in the second direction (X1 / X2). One end of the reset member 65 is connected to the blocking body 511, and the other end is connected to the mating member 63. Thus, when the mating member 63 moves from the locked position to the second unlocked position along the second direction (X1 / X2), the reset member 65 can generate a reset force, which can reset the mating member 63 from the second unlocked position to the locked position.

[0165] Along the height direction (Z1 / Z2) of the charging box 100 (i.e., the first direction (Z1 / Z2)), the reset member 65 is located below the mating member 63, and the support member 53 can support the mating member 63. In this way, the support member 53 can guide the movement of the mating member 63 and prevent the mating member 63 from shifting during the movement. For example, the mating member 63 may shift downwards during the movement along the second direction (X1 / X2), thereby ensuring the stability of the movement of the mating member 63 and improving the stability and reliability of the button structure 60.

[0166] Furthermore, in some embodiments, the mating member 63 includes a contact surface opposite to the support member 53 (the side of the mating 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. Therefore, compared to a situation where the contact area between the support member 53 and the contact surface is equal to the area of ​​the contact surface, the friction between the mating member 63 and the support member 53 is smaller, thereby facilitating the movement of the mating member 63 relative to the support member 53 along the second direction (X1 / X2).

[0167] As described above, when the mating part 63 is subjected to the first force, the cover 20 can switch from the pressed position to the released position. In other words, in order to switch the cover 20 from the pressed position to the released position, the first force needs to be applied to the mating part 63. However, since the mating part 63 is located inside the base 10, it may be difficult for the user to reach into the base 10 to apply force to the mating part 63, which will affect the normal use of the charging case 100.

[0168] In some embodiments of this application, the button structure 60 further includes a pressing member 69, which is connected to the mating member 63 and can move along the second direction (X1 / X2) together with the mating member 63. The pressing member 69 is exposed from the side wall of the base 10. Thus, the user can apply a first force to the mating member 63 without reaching into the base 10; that is, the user can apply a first force to the mating member 63 through the pressing member 69, thereby ensuring the normal use of the charging case 100.

[0169] In some embodiments, the pressing member 69 and the mating member 63 are an integral structure, that is, the pressing member 69 and the mating member 63 can be integrally formed into a whole, which can improve the stability of the connection between the pressing member 69 and the mating member 63 and prevent the pressing member 69 from falling off the mating member 63 when the user presses it.

[0170] In other embodiments, the pressing member 69 and the mating member 63 are separate structures, 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 joined together by a detachable connection method, including but not limited to snap-fit ​​connections or bolt connections. In another example, the pressing member 69 and the mating member 63 can be joined together by a non-detachable connection method, including but not limited to bonding or welding.

[0171] Please refer to Figures 7, 12, and 14. In some embodiments of this application, the base 10 is provided with at least one through hole 104. The charging case 100 also includes a sealing assembly 50, which is disposed on the base 10 and serves to prevent external fluid from entering the interior of the base 10 through the through hole 104. This prevents external fluid from damaging the internal components of the base 10, enhances waterproofing, and ensures the normal operation of the charging case 100.

[0172] It should be noted that in some embodiments of this application, 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 also 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.

[0173] Referring to Figure 7, in some embodiments, the base 10 is provided with a first through hole 1041, which penetrates the side wall and / or bottom wall of the base 10. At least a portion of the mating member 63 is located within the base 10, and the pressing member 69 passes through the first through hole 1041 and is connected to the mating member 63. It is understood that in some embodiments, the pressing member 69 can achieve reciprocating movement in the first through hole 1041 through its cooperation with the mating member 63 and the reset member 65.

[0174] Specifically, in some embodiments, the shape and size of the cross-section of the pressing member 69 cut by a plane perpendicular to the second direction (X1 / X2) are approximately the same as the shape and size of the cross-section of the first through hole 1041 cut by a plane perpendicular to the second direction (X1 / X2). This not only ensures that the pressing member 69 can slide relative to the base 10 within the first through hole 1041 when pressed, but also reduces the gap between the pressing member 69 and the inner wall of the first through hole 1041, reducing or even preventing external water or dust from entering the base 10 through the gap between the pressing member 69 and the first through hole 1041. This ensures the normal operation of the structures inside the base 10 (such as the rechargeable battery 110 and the circuit board 120).

[0175] In some embodiments, the first through hole 1041 penetrates the side wall of the base 10, which can improve the user's ease of use, for example, making it easier for the user to operate the charging case 100 with one hand.

[0176] In other embodiments, the first through hole 1041 penetrates the bottom wall of the base 10. This reduces the possibility of water or dust entering the base 10 through the first through hole 1041, preventing damage to the internal structure of the base 10 and ensuring the normal operation of the charging box 100. On the other hand, it facilitates the outflow of liquid inside the base 10 through the first through hole 1041, preventing liquid from accumulating inside the base 10 and causing damage to the internal structure of the base 10.

[0177] In some other embodiments, the first through hole 1041 penetrates both the side wall and the bottom wall of the base 10. This increases the size of the first through hole 1041, allowing the user to insert their arm into the base 10 through the first through hole 1041 to apply a first force to the mating part 63, thus facilitating user operation. Furthermore, it allows liquid inside the base 10 to flow out through the first through hole 1041, preventing liquid accumulation inside the base 10 from damaging its internal structure.

[0178] In some embodiments, the two 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 mating member 63 and the resetting member 65 are both housed in the first cavity 1021, and the first through hole 1041 communicates with the first cavity 1021.

[0179] Specifically, in some embodiments, the base 10 is provided with a receiving cavity 102 for accommodating structures such as the rechargeable battery 110 and the 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. The mating member 63 and the resetting member 65 are both housed in the first cavity 1021, the first through hole 1041 communicates with the first cavity 1021, and the rechargeable battery 110 and the circuit board 120 are housed in the second cavity 1023. Therefore, when external liquid enters the receiving cavity 102 through the first through hole 1041, the blocking member 51 can block the external liquid within the first cavity 1021, preventing damage to the rechargeable battery 110 and the circuit board 120, thereby ensuring the normal operation of the charging box 100.

[0180] In some embodiments, the base 10 is provided with a limiting member 55, and the pressing member 69 includes an extension wall 691. The limiting member 55 partially encloses the extension wall 691 to at least limit the extension wall 691 from tilting toward the cover 20.

[0181] Specifically, in some embodiments, the limiting member 55 is disposed in the first cavity 1021. One end of the limiting 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 extension wall 691 can be the side wall of the pressing member 69 in the third direction (Y1 / Y2), which is perpendicular to the first direction (Z1 / Z2) and also perpendicular to the second direction (X1 / X2).

[0182] Among them, the limiting member 55 partially encloses the extension wall 691. That is, the shape, size and outline of the side of the limiting member 55 opposite to the extension wall 691 are exactly the same or almost exactly the same as the shape, size and outline of the extension wall 691. In this way, the limiting member 55 can cooperate with the extension wall 691 to prevent the extension wall 691 from tilting towards the cover 20 and causing the movement of the pressing member 69 to deviate. This ensures the stability of the movement of the pressing member 69 and the mating member 63, thereby improving the stability and reliability of the button structure 60.

[0183] Furthermore, in some embodiments, the limiting member 55 includes a first limiting member 551 and a second limiting member 553, and the extension wall 691 includes a first extension wall 693 and a second extension wall 695. The first limiting member 551 covers at least a portion of the first extension wall 693 and at least limits the first extension wall 693 from tilting toward the cover 20. The second limiting member 553 covers at least a portion of the second extension wall 695 and at least limits the second extension wall 695 from tilting toward the cover 20.

[0184] Specifically, in some embodiments, the first extension wall 693 and the second extension wall 695 may be two opposite sidewalls of the pressing member 69 in a third direction (Y1 / Y2). Compared to the limiting member 55 including only the first limiting member 551 or the second limiting member 553, the provision of the first limiting member 551 and the second limiting member 553 can further improve the stability of the pressing member 69 moving along 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 button structure 60 in operation.

[0185] In some embodiments, the first limiting member 551, the second limiting member 553, and the blocking member 51 together form a sub-cavity 10211, and the first through hole 1041 communicates with the sub-cavity 10211.

[0186] Specifically, in some embodiments, the sub-cavity 10211 is located inside the first cavity 1021, and at least a portion of the mating member 63 is located in the sub-cavity 10211. This further prevents external liquids from entering the second cavity 1023, which could damage the rechargeable battery 110 and circuit board 120 in the second cavity 1023, thereby ensuring the normal operation of the charging box 100.

[0187] In related technologies, the cover 20 and the base 10 are usually fitted with a gap to improve the smoothness of the movement of the cover 20 relative to the base 10. However, a gap between the cover 20 and the base 10 will result in poor stability and a poor user experience when the cover 20 moves relative to the base 10. Referring to Figures 3 and 10, in some embodiments of this application, the charging case 100 also includes a damping element 70, which is used to limit the degree of freedom of the extension 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. This can prevent the extension 23 from moving or wobbling in the horizontal direction, thereby improving the stability of the cover 20 moving relative to the base 10 and improving the user experience; on the other hand, it can avoid the extension 23 wobbling relative to the base 10 in the horizontal direction during the lifting and lowering of the cover 20 relative to the base 10, which would cause excessive noise, 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).

[0188] Specifically, in some embodiments, the damping member 70 may be disposed in the moving space and cooperate with the inner wall 131 of both the extension 23 and the connector 13. In this way, the damping member 70 can restrict the degree of freedom of the extension 23 in the horizontal direction. That is, the damping member 70 can block the movement of the extension 23 in the horizontal direction, thereby improving the stability of the cover 20 when it moves (e.g., lifts or lowers) relative to the base 10.

[0189] Referring to 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, which mates with the extension 23 of the cover 20. The elastic protrusion 73 protrudes from the damping body 71 and includes a second mating surface 731, which mates with the inner wall 131 of the connector 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.

[0190] The damping body 71 is a structure in the damping member 70 that can mate with the extension member 23. In some embodiments of this application, the damping body 71 is connected to the side wall 231 of the extension member 23, and when the damping body 71 and the extension member 23 are connected, the first mating surface 711 abuts against the side wall 231 of the extension member 23. The damping body 71 and the extension member 23 can be connected together using a detachable or non-detachable connection method. Detachable connection methods include, but are not limited to, snap-fit ​​connections or bolt connections; non-detachable connection methods include, but are not limited to, adhesive or welding.

[0191] For example, the damping body 71 is provided with a through connection hole 717, through which the fastener 106 can connect the damping body 71 to the side wall 231 of the extension 23. It should be noted that in some embodiments, the fastener 106 may be a bolt or screw, etc.

[0192] The elastic protrusion 73 is a structure in the damping member 70 that can cooperate with the connector 13. In some embodiments of this application, when the extension 23 extends into the connector 13, the second mating surface 731 can cooperate (contact) with the inner wall 131 of the connector 13. In this way, the provision of the elastic protrusion 73 can restrict the degree of freedom of the extension 23 in the horizontal direction, prevent the extension 23 from moving or swaying in the horizontal direction, thereby improving the stability of the cover 20 when moving relative to the base 10 and improving the operating feel.

[0193] It is understood that the elastic protrusion 73 can undergo elastic deformation and generate elastic restoring force, and the elastic restoring force generated by the elastic protrusion 73 can keep the second mating surface 731 in contact with the inner wall 131 of the connector 13.

[0194] Specifically, when the extension 23 extends into the connector 13, the inner wall 131 of the connector 13 can exert pressure on the elastic protrusion 73. Under the pressure, the elastic protrusion 73 elastically deforms towards 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 connector 13. Therefore, compared to the elastic protrusion 73 not being able to generate elastic deformation, the elastic protrusion 73 in this embodiment can avoid the problem that the second mating surface 731 cannot mate with the inner wall 131 of the connector 13 due to unevenness of the inner wall 131, effectively preventing the extension 23 from moving or wobbling in the horizontal direction and improving the stability of the cover 20 relative to the base 10 when moving.

[0195] In some embodiments, the damping element 70 is made of metal.

[0196] Specifically, in some embodiments, the damping body 71 and the elastic protrusion 73 are made of the same material. For example, both the damping body 71 and the elastic protrusion 73 are made of elastic metal, in which case the damping element 70 is an elastic metal element. Elastic metals include, but are not limited to, titanium bronze, phosphor bronze, beryllium bronze, manganese steel, and stainless steel. In other embodiments, the damping body 71 and the elastic protrusion 73 are made of different materials. For example, the damping body 71 may be made of a non-elastic metal or an elastic metal; the elastic protrusion 73 may be made of an elastic metal.

[0197] It is understood that in other embodiments, the damping element 70 may also be made of a non-metallic material. For example, the damping element 70 may also be made of at least one of non-metallic elastic materials such as rubber and silicone.

[0198] In some embodiments, the damping body 71 and the elastic protrusion 73 are integrally stamped structures. That is, the damping body 71 and the elastic protrusion 73 can be formed into an integral structure by integral stamping. This facilitates the processing and manufacturing of the damping component 70 and improves the production efficiency of the damping component 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 the damping body 71, and extend the service life of the damping component 70.

[0199] In other embodiments, the damping body 71 and the elastic protrusion 73 are separate structures, that is, the damping body 71 and the elastic protrusion 73 are two different structures. The damping body 71 and the elastic protrusion 73 can be connected together using either a detachable or non-detachable connection method. Detachable connection methods include, but are not limited to, snap-fit ​​connections or bolt connections; non-detachable connection methods include, but are not limited to, adhesive or welding.

[0200] In summary, the damping component 70 includes a damping body 71 and an elastic protrusion 73. The first mating surface 711 of the damping body 71 can mate with the extension 23. The elastic protrusion 73 protrudes from the damping body 71 and the second mating surface 731 of the elastic protrusion 73 can mate with the inner wall 131 of the connector 13. Thus, the elastic protrusion 73 can restrict the degree of freedom of the extension 23 in the horizontal direction, preventing the extension 23 from moving or swaying in the horizontal direction, thereby improving the stability of the cover 20 when moving relative to the base 10 and improving the operating feel.

[0201] In addition, the damping component 70 can prevent the extension component 23 from shaking horizontally relative to the base 10 during the lifting and lowering of the cover 20 relative to the base 10, thus avoiding excessive noise and improving the user experience.

[0202] If there is only one elastic protrusion 73, or if there are at least two elastic protrusions 73, and the at least two elastic protrusions 73 are collinearly arranged, the extension 23 is prone to deflection or wobbling in the connector 13 during the movement of the cover 20 relative to the base 10, which will affect the stability of the cover 20 during the movement relative to the base 10. For example, if there are three elastic protrusions 73, and the three elastic protrusions 73 are collinearly arranged along the height direction (Z1 / Z2)Z of the charging case 100, the extension 23 is prone to deflection in the connector 13 about the height direction (Z1 / Z2)Z of the charging case 100 during the movement of the cover 20 relative to the base 10.

[0203] In some embodiments of this application, the elastic protrusions 73 include at least three, and the centers of the at least three elastic protrusions 73 are not collinear. Non-collinear arrangement means that the arrangement of two or more elements (e.g., structural members) in space does not satisfy the collinearity condition; that is, there is no single, straight, unbent line that can simultaneously pass through all the elements. The fact that the centers of the at least three elastic protrusions 73 are not collinear means that the centers of the at least three elastic protrusions 73 can collectively form a stable geometry, thereby preventing the extension 23 from deflecting or wobbling in the connector 13 during the movement of the cover 20 relative to the base 10, and further improving the stability of the cover 20 during movement relative to the base 10.

[0204] For example, in some embodiments, when the elastic protrusions 73 include three and the centers of the three elastic protrusions 73 are not collinear, the line connecting the centers of the three elastic protrusions 73 can form a triangle. Thus, compared to the three elastic protrusions 73 being collinear, the extension 23 is less likely to deflect or wobble in the connector 13 during the movement of the cover 20 relative to the base 10, thereby further improving the stability of the cover 20 when it moves relative to the base 10.

[0205] In some embodiments, the resilient protrusions 73 include at least three, which are evenly distributed around the center of the sidewall 231 of the extension 23. This provides more stable support for the extension 23 while preventing it from deflecting or wobbling in the connector 13, thereby further improving the stability of the cover 20 relative to the base 10 during movement.

[0206] Referring to Figure 11, in some embodiments, the elastic protrusion 73 includes a first sub-part 733 and a second sub-part 735 that are bent together. The first sub-part 733 extends from the damping body 71 in a direction away from the first mating surface 711, and the second sub-part 735 extends from the end of the first sub-part 733 away from the damping body 71 toward the first mating surface 711. The connection 737 of the first sub-part 733 and the second sub-part 735 is configured to participate in forming the second mating surface 731.

[0207] Specifically, referring to the figures, in some embodiments, the free end 739 of the elastic protrusion 73 is spaced apart from the first mating surface 711, that is, the end of the second sub-part 735 away from the first sub-part 733 is spaced apart from the first mating surface 711. This ensures that the elastic protrusion 73 can undergo elastic deformation when subjected to force. The connection 737 between the first sub-part 733 and the second sub-part 735 is the bend between them. When the extension 23 extends into the connector 13, the connection 737 between the first sub-part 733 and the second sub-part 735 can abut against the inner wall 131 of the connector 13. That is, the contact surface between the elastic protrusion 73 and the inner wall 131 of the connector 13 can be an arc surface. This reduces the friction between the elastic protrusion 73 and the connector 13, preventing excessive friction from 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.

[0208] It should be noted that in some embodiments, when there are multiple elastic protrusions 73, the connection points 737 of the multiple elastic protrusions 73 (the connection points 737 of the first sub-part 733 and the second sub-part 735) can jointly form the second mating surface 731.

[0209] In some embodiments, the damping body 71 is provided with a clearance space 715, at least a portion of the elastic protrusion 73 is disposed in the clearance space 715, and the free end 739 of the elastic protrusion 73 is spaced apart from the bottom wall of the clearance space 715.

[0210] Specifically, in some embodiments, the damping body 71 further includes a third mating surface 713 opposite to the first mating surface 711, and a clearance space 715 is recessed from the third mating surface 713 toward the first mating surface 711. The clearance space 715 provides deformation space for the elastic protrusion 73, preventing it from directly contacting the third mating surface 713 when deformed under force; it also reduces the space occupied by the damping body 71 and the elastic protrusion 73, facilitating miniaturization of the damping component 70; and it further reduces the weight of the damping component 70, contributing to its lightweight design.

[0211] In some embodiments, the clearance space 715 may be a through groove, that is, the clearance space 715 penetrates through the first mating surface 711 and the third mating surface 713. In this case, the bottom wall of the clearance space 715 coincides with the first mating surface 711. In other embodiments, the clearance space 715 may be a blind groove, that is, the clearance space 715 is recessed from the third mating surface 713 toward the first mating surface 711 and does not penetrate the first mating surface 711.

[0212] In some embodiments, the damping body 71 has a flat plate structure. This facilitates the fabrication of the elastic protrusions 73, ensuring that when there are multiple elastic protrusions 73, the connection points 737 of the multiple elastic protrusions 73 can be in the same plane, thereby improving the product yield of the damping component 70.

[0213] Referring to Figures 10 and 11, in some embodiments, a clearance groove may be provided on the side wall 231 of the extension 23. The clearance groove is recessed from the side wall 231 of the extension 23 toward the center of the extension 23, and at least a portion of the damping member 70 is disposed in the clearance groove. Thus, the provision of the clearance groove can, on the one hand, reduce the space occupied by the damping member 70, which is beneficial to the miniaturization of the charging box 100; on the other hand, it can facilitate the installation and positioning of the damping member 70, thereby improving the assembly efficiency of the charging box 100.

[0214] In some embodiments, the damping element 70 includes two damping elements 70, which are respectively disposed on opposite sides of the extension 23 in the horizontal direction. This can further improve the stability of the cover 20 when moving relative to the base 10 and improve the operating feel.

[0215] For example, the extension 23 includes a first side 2311, a second side 2313, a third side 2315 and a fourth side 2317 connected in sequence, and two damping members 70 are respectively disposed on the first side 2311 and the third side 2315 of the extension; or, the two damping members 70 are respectively disposed on the second side 2313 and the fourth side 2317 of the extension.

[0216] In some embodiments, two damping elements 70 are respectively disposed on the first side 2311 and the third side 2315 of the extension, a first guide element 41 is disposed on the second side 2313 and / or the fourth side 2317 of the extension, and a second guide element 43 is disposed on the second side 1313 and / or the fourth side 1317 of the inner wall of the connector 13. The second side 1313 of the inner wall of the connector 13 is opposite to the second side 2313 of the extension, and the fourth side 1317 of the inner wall of the connector 13 is opposite to the fourth side 2317 of the extension. This prevents interference between the first guide element 41 and the damping element 70, thereby ensuring the fit between the first guide element 41 and the second guide element 43, and ensuring the normal assembly of the damping element 70, thus improving the stability of the cover 20 relative to the base 10.

[0217] Specifically, in some embodiments, when the first guide 41 is disposed on the second side 2313 of the extension, the second guide 43 is disposed on the second side 1313 of the inner wall of the connector 13; when the first guide 41 is disposed on the fourth side 2317 of the extension, the second guide 43 is disposed on the fourth side 1317 of the inner wall of the connector 13.

[0218] It should be noted that, in some embodiments, the first guide 41 includes at least one on the same side of the extension 23 (e.g., the first side 2311, the second side 2313, the third side 2315, or the fourth side 2317 of the extension). The quantitative relationship between the first guide 41 and the second guide 43 can be one-to-one or one-to-many, that is, one first guide 41 corresponds to one second guide 43; or, one first guide 41 corresponds to multiple second guides 43.

[0219] In other embodiments, two damping elements 70 are respectively disposed on the first side 2311 and the third side 2315 of the extension, a first guide element 41 is disposed on the first side 2311 and / or the third side 2315 of the extension, and a second guide element 43 is disposed on the first side 1311 and / or the third side 1315 of the inner wall of the connector 13. The first side 1311 of the inner wall of the connector 13 is opposite to the first side 2311 of the extension, and the third side 1315 of the inner wall of the connector 13 is opposite to the third side 2315 of the extension. The first guide element 41 and the damping element 70 are spaced apart. This prevents interference between the first guide element 41 and the damping element 70, thereby ensuring the cooperation between the first guide element 41 and the second guide element 43, and ensuring the normal assembly of the damping element 70, thereby improving the stability of the cover 20 relative to the base 10.

[0220] Please refer to Figures 3, 4, and 6. In some embodiments, the weight of the cover 20 is less than the weight of the base 10. This prevents the charging case 100 from having a high center of gravity, thereby reducing the possibility of the charging case 100 tipping over when placed and improving the stability of the charging case 100 when placed.

[0221] In addition, the weight of the cover 20 is less than the weight of the base 10. On the one hand, compared with the weight of the cover 20 being greater than or equal to the weight of the base 10, the overall weight of the charging case 100 is smaller, making it easier for users to carry. On the other hand, it can prevent the cover 20 from being too heavy, making it difficult or even impossible for the cover 20 to move relative to the base 10, thereby ensuring the normal use of the charging case 100.

[0222] Specifically, in some embodiments, the weight of the cover 20 being less than the weight of the base 10 can be: the weight of the cover 20 itself is less than the weight of the base 10 itself; or, the weight of the overall structure formed by the cover 20 and the structures disposed on the cover 20 is less than the weight of the base 10 itself; or, the weight of the overall structure formed by the cover 20 and the structures disposed on the cover 20 is less than the weight of the overall structure formed by the base 10 and the structures disposed on the base 10 (e.g., the structure formed by the base 10, the circuit board 120 disposed on the base 10, and the rechargeable battery 110). It is understood that in some embodiments of this application, no additional structures are provided on the cover 20.

[0223] In some embodiments, the orthographic projection of the cover 20 onto the base 10 lies entirely within the area of ​​the base 10. That is, the projection of the cover 20 in the height direction (Z1 / Z2) perpendicular to the charging case 100 lies within the projection of the base 10 in the same height direction (Z1 / Z2). This ensures that the center of gravity of the charging case 100 is within the area of ​​the base 10. Compared to the case where the center of gravity is outside the base 10, the charging case 100 is less likely to tip over when placed, thus improving its stability. It should be noted that the height direction (Z1 / Z2) of the charging case 100 can be: the direction from the cover 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 20.

[0224] In other embodiments, the projection of the cover 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. This ensures that the center of gravity of the charging case 100 is located within the area of ​​the base 10, reducing the likelihood of the charging case 100 tipping over when placed compared to when its center of gravity is outside the area of ​​the base 10, thereby improving the stability of the charging case 100.

[0225] In this embodiment, the example given is that the cross-section of the cover 20 cut by a plane perpendicular to the height direction (Z1 / Z2) of the charging box 100 is smaller than the cross-section of the base 10 cut by a plane perpendicular to the height direction (Z1 / Z2) of the charging box 100.

[0226] In some embodiments, at least a portion of the cover 20 is a hollow structure.

[0227] Specifically, in some embodiments, the cover 20 may have a cavity inside (including a first cavity 210 and a second cavity 230). Therefore, compared to a solid structure, the cover 20 is lighter, preventing the center of gravity of the charging case 100 from being closer to the cover 20 than the base 10, thereby improving the stability of the charging case 100. Furthermore, at least a portion of the cover 20 being hollow can reduce material usage, thereby lowering the production cost of the charging case 100.

[0228] Further, referring 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. In this case, the interior of the main body 21 may have a first cavity 210. In another example, the extension 23 is a hollow structure. In this case, the interior of the extension 23 may have a second cavity 230. In yet another example, both the main body 21 and the extension 23 are hollow structures. In this case, the interior of the main body 21 may have a first cavity 210, and the interior of the extension 23 may have a second cavity 230.

[0229] More specifically, the main body 21 may include a first sub-part 211 and a second sub-part 213. If the main body 21 has 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 together form a first cavity 210. Therefore, compared to a solid structure for the cover 20, that is, compared to a structure where the first sub-part 211 and the second sub-part 213 are combined and there is no first cavity 210, the cover 20 is lighter in weight.

[0230] 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 integral molding, which can improve the sealing of the main body 21 and prevent external water or dust from entering the main body 21, thereby improving the stability and reliability of the charging box 100.

[0231] In another example, the first sub-part 211 and the second sub-part 213 are separate structures, that is, the first sub-part 211 and the second sub-part 213 are two different structures. The first sub-part 211 and the second sub-part 213 can be combined by a detachable connection method or a non-detachable connection method. The detachable connection method includes, but is not limited to, snap-fit ​​connection or bolt connection; the non-detachable connection method includes, but is not limited to, adhesive or welding.

[0232] Referring to Figure 6, in some embodiments, the cover 20 is provided with reinforcing ribs 27, which protrude from the inner wall of the cover 20 toward the center of the cover 20. The reinforcing ribs 27 increase the structural strength of the cover 20 and reduce the possibility of deformation and damage. Furthermore, compared to reinforcing ribs 27 protruding away from the cover 20, the reinforcing ribs 27 in this embodiment are not visible to the user, thus improving the appearance of the charging case 100.

[0233] In some embodiments of this application, the reinforcing rib 27 may extend from the first sub-part 211 toward the center of the cavity (the first cavity 210 formed by the combination of the first sub-part 211 and the second sub-part 213); and / or, the reinforcing rib 27 may extend from the second sub-part 213 toward the center of the cavity, thereby improving the structural strength of the cover 20 while achieving a lightweight design. It is understood that when the cover 20 is provided with the reinforcing rib 27, the overall weight of the cover 20 and the reinforcing rib 27 is also less than the weight of the base 10.

[0234] Please refer to Figures 3 and 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 makes the cover 20 lighter, thereby preventing the center of gravity of the charging case 100 from being closer to the cover 20 than the base 10. That is, it makes the center of the charging case 100 lower, which reduces the possibility of the charging case 100 tilting when placed and improves the stability of the charging case 100 when placed.

[0235] For example, when the volume of the cover 20 is smaller than the volume of the base 10 and the cover 20 and the base 10 are made of the same material, 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 less than the wall thickness of the base 10, the weight of the cover 20 is less than the weight of the base 10.

[0236] 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 makes the cover 20 lighter, 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, thereby reducing the possibility of the charging case 100 tilting when placed and improving the stability of the charging case 100 when placed.

[0237] For example, 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 is 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.

[0238] In summary, in some embodiments of this application, the weight of the cover 20 is less than the weight of the base 10 when at least one of the following conditions is met: at least a portion 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.

[0239] For example, if at least a portion of the cover 20 is a hollow structure, the volume of the cover 20 is smaller than the volume of the base 10, the wall thickness of the cover 20 is smaller than the wall thickness of the base 10, and the density of the material of the cover 20 is smaller than the density of the material of the base 10, then the weight of the cover 20 is less than the weight of the base 10. This can prevent the center of gravity of the charging box 100 from being too high, reduce the possibility of the charging box 100 tilting when placed, and improve the stability of the charging box 100 when placed.

[0240] Referring to Figures 6 and 12, in some embodiments, the charging case 100 further includes a position detection component 80 and a prompting component 90. The position detection component 80 is disposed on the cover 20 and the base 10, and is used to detect the movement distance of the cover 20 relative to the base 10. The prompting component 90 changes its state based on the movement distance detected by the position detection component 80, and the state of the prompting component 90 includes at least a triggered state.

[0241] The position detection component 80 is a structure used to detect the movement 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 movement distance of the cover 20 relative to the base 10 through the cooperation between a first detection element (e.g., a magnetic element 83) disposed in the cover 20 and a second detection element (e.g., a Hall sensor 81) disposed in the base 10.

[0242] Specifically, the position detection component 80 detects the moving distance by methods including, but not limited to, detecting magnetic flux, detecting pressure, and detecting infrared radiation. The number of the first and second detection elements can be one or more, and is not limited in this application. In one example, the number of the first and second detection elements is the same; in another example, the number of the first and second detection elements is different.

[0243] The prompt component 90 changes its state based on the movement distance detected by the position detection component 80. That is, the state of the prompt component 90 can be different depending on the movement distance of the cover 20 relative to the base 10. The state of the prompt component 90 includes at least a triggered state, in which the prompt component 90 can emit an indication signal to characterize different parameters of the charging case 100, including but not limited to power consumption, remaining power, and temperature.

[0244] The prompting component 90 includes at least one prompting element, which changes its state based on the movement distance detected by the position detection component 80. The indication signals emitted by the prompting element include, but are not limited to, indicator lights and indicator sounds. In one example, the prompting component 90 may have one prompting element. In another example, the prompting component 90 may have at least two prompting elements. In embodiments with multiple prompting elements, the indication signals emitted by the multiple prompting elements may be the same or different.

[0245] In summary, the charging case 100 can use the position detection component 80 set on the cover 20 and the base 11 to detect the movement distance of the cover 20 relative to the base 10. The prompting component 90 changes its state based on the detected movement distance to represent different parameters of the charging case 100. This allows users to intuitively obtain the state of the charging case 100 corresponding to the parameters of the charging case 100, and realize real-time monitoring of the charging case 100.

[0246] Referring to Figure 6, in some embodiments, the position detection component 80 includes a Hall sensor 81 and a magnetic element 83. The magnetic element 83 is disposed inside the cover 20 and moves with the cover 20. The Hall sensor 81 is disposed inside the base 10. The Hall sensor 81 cooperates with the magnetic element 83. The Hall sensor 81 detects the moving distance of the cover 20 relative to the base 10 by the change in magnetic flux.

[0247] Specifically, in this application, the position detection component 80 detects the movement distance of the cover 20 relative to the base 10 by the change in magnetic flux. The change in magnetic flux characterizing the movement distance of the cover 20 relative to the base 10 can be characterized by the change in magnetic flux of a set of Hall sensors 81 and magnetic elements 83, or it can be characterized by the change in magnetic flux of multiple sets of Hall sensors 81 and magnetic elements 83 in a certain combination.

[0248] In one example, a magnetic element 83 is disposed within the cover 20, and a Hall sensor 81 is disposed within the base 10. The Hall sensor 81 disposed within the base 10 senses changes in the magnetic flux of the magnetic element 83 disposed within the cover 20 to detect the movement distance of the cover 20 relative to the base 10. In another example, a Hall sensor 81 is disposed within the cover 20, and a magnetic element 83 is disposed within the base 10. The Hall sensor 81 disposed within the cover 20 senses changes in the magnetic flux of the magnetic element 83 disposed within the base 10 to detect the movement distance of the cover 20 relative to the base 10. In yet another example, a magnetic element 83 and a Hall sensor 81 are disposed within the cover 20, and a magnetic element 83 and a Hall sensor 81 are also disposed within the base 10. The Hall sensor 81 disposed within the base 10 senses changes in the magnetic flux of the magnetic element 83 disposed within the cover 20, and the Hall sensor 81 disposed within the cover 20 senses changes in the magnetic flux of the magnetic element 83 disposed within the base 10. The Hall sensor 81 is small in size and easy to integrate into the charging case 100. The Hall sensor 81 has low power consumption, making it suitable for portable devices such as the charging case 100 and helping to extend the battery life of the charging case 100.

[0249] In some embodiments, when the movement distance indicates that the cover 20 is in the pressed position, the state of the prompting component 90 is in the dormant state; when the movement distance indicates that the cover 20 has moved to a predetermined position, the state of the prompting component 90 is in the triggered state, and an indication signal is issued to indicate the charging parameters of the charging box 100. The pressed position is the position where the cover 20 is pressed against the component to be charged placed on the base 10.

[0250] The predetermined positions include the release position and any position between the pressing position and the release position. The release position is the position where the cover 20 has moved the maximum distance relative to the base 10, and the pressing position is the position where the cover 20 presses against the charging component placed on the base 10. This allows for more diverse and flexible settings for when the indicator light assembly 91 emits an indicator signal.

[0251] Specifically, when the cover 20 is in the pressed position, the indicator component 90 is in a dormant state, which indicates that the cover 20 is in the pressed position; when the cover 20 is in a predetermined position, the indicator component 90 is in a triggered state and issues an indication signal to indicate the parameters of the charging case 100. That is, in the triggered state, the indicator component 90 can issue an indication signal to indicate the parameters of the charging case 100, thereby indicating the state of the charging case 100.

[0252] Please refer to Figures 6 and 12. In some embodiments, the prompt component 90 is an indicator light component 91. The state of the prompt component 90 includes a sleep state and a triggered state. The indication signal includes an indicator light. When the movement distance indicates that the cover 20 is in the pressed position, the state of the indicator light component 91 is the sleep state. When the movement distance indicates that the cover 20 has moved to a predetermined position, the state of the indicator light component 91 is the triggered state and emits an indicator light to indicate the charging parameters of the charging box 100.

[0253] The indicator light assembly 91 includes at least one prompting element, which changes its state based on the movement distance detected by the position detection assembly 80. In one embodiment, the prompting element emits an indicator light signal, and the prompting element includes, but is not limited to, an LED, a laser diode, or other types of light-emitting elements. In one example, the prompting assembly 90 may have one prompting element. In another example, the prompting assembly 90 may have at least two prompting elements. In embodiments with multiple prompting elements, the multiple prompting elements may be of the same or different types. The cross-sectional shape of the prompting element may be circular, elliptical, triangular, quadrilateral, or other polygonal, etc., and is not limited thereto.

[0254] When the cover 20 is in the pressed position, the indicator light assembly 91 is in a sleep state. In the sleep state, the indicator light assembly 91 does not emit any indicator light; that is, the indicator light assembly 91 is off. When the cover 20 moves from the pressed position to a predetermined position, the indicator light assembly 91 switches from the sleep state to the triggered state and emits an indicator light; that is, the indicator light assembly 91 is lit. In the triggered state, the parameters of the indicator light emitted by the indicator light assembly 91 include, but are not limited to, the brightness, color, and flashing frequency of the indicator light. These parameters of the indicator light reflect the parameters of the charging case 100.

[0255] In some implementations, the indicator light has different brightness levels, with different brightness levels representing different parameter values ​​of the same parameter of the charging case 100.

[0256] Specifically, the parameters of the indicator light include its brightness. When the cover 20 moves to a predetermined position and the indicator light assembly 91 is in a triggered state and emits an indicator light, the indicator light, through different brightness levels, represents different parameter values ​​of the same parameter of the charging case 100. At this time, the parameters of the charging case 100 include, but are not limited to, the power consumed, the remaining power, and the temperature of the charging case 100. Correspondingly, the parameter values ​​include, but are not limited to, the power consumed value, the remaining power value, and the temperature value. The brightness and the different parameter values ​​of the same parameter of the charging case 100 can be positively correlated or negatively correlated.

[0257] 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 indicator light is positively correlated with the remaining power, the brightness of the indicator light includes at least a first brightness, a second brightness, and a third brightness, wherein 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 includes at least a first remaining power value, a second remaining power value, and a third remaining power value, wherein 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 represents the cover 20 moving to a predetermined position, if the brightness of the indicator light is the first brightness (e.g., 100), the remaining power of the charging case 100 is represented by the first remaining power value (e.g., 90%); if the brightness of the indicator light is the second brightness (e.g., 80), the remaining power of the charging case 100 is represented by the second remaining power value (e.g., 80%); and if the brightness of the indicator light is the third brightness (e.g., 60), the remaining power of the charging case 100 is represented by the third remaining power value (e.g., 60%). Therefore, the charging box 100 can represent different parameter values ​​of the same parameter by different brightness of the indicator light, so that the user can obtain different states of the charging box 100 according to different brightness of the indicator light.

[0258] In some implementations, the indicator light has different colors, and the different colors represent different parameter values ​​of the same parameter of the charging box 100.

[0259] Specifically, the parameters of the indicator light include its color. When the cover 20 moves to a predetermined position and the indicator light assembly 91 is in a triggered state and emits indicator light, the indicator light uses different colors to represent different parameter values ​​of the same parameter of the charging case 100. At this time, the parameters of the charging case 100 include, but are not limited to, the power consumed, the remaining power, and the temperature of the charging case 100. Correspondingly, the parameter values ​​include, but are not limited to, the power consumed value, the remaining power value, and the temperature value.

[0260] For example, in an embodiment where the parameter of the charging case 100 is temperature, and the parameter value is a temperature value, the color includes at least a first color (e.g., red), a second color (e.g., yellow), and a third color (e.g., blue). The temperature value includes at least a first temperature value, a second temperature value, and a third temperature value, wherein the first temperature value is greater than the second temperature value, and the second temperature value is greater than the third temperature value. Therefore, when the moving distance represents the cover 20 moving to a predetermined position, if the indicator light is the first color, it represents the temperature of the charging case 100 as the first temperature value (e.g., 40°C); if the indicator light is the second color, it represents the temperature of the charging case 100 as the second temperature value (e.g., 30°C); and if the indicator light is the third color, it represents the temperature of the charging case 100 as the third temperature value (e.g., 25°C). Thus, the charging case 100 can represent different parameter values ​​of the same parameter using different colors of the indicator light, allowing the user to obtain different states of the charging case 100 based on the different colors of the indicator light.

[0261] In some implementations, the indicator light has different flashing frequencies, and the different flashing frequencies characterize different parameter values ​​of the same parameter of the charging box 100.

[0262] Specifically, the parameters of the indicator light include its flashing frequency. When the moving distance represents the cover 20 moving to a predetermined position, and the indicator light assembly 91 is in a triggered state and emits an indicator light, the indicator light, through different flashing frequencies, represents different parameter values ​​of the same parameter of the charging case 100. At this time, the parameters of the charging case 100 include, but are not limited to, the power consumed, the remaining power, and the temperature of the charging case 100. Correspondingly, the parameter values ​​include, but are not limited to, the power consumed value, the remaining power value, and the temperature value. The flashing frequency and the different parameter values ​​of the same parameter of the charging case 100 can be positively correlated or negatively correlated.

[0263] 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 flashing frequency of the indicator light is negatively correlated with the remaining power, the flashing frequency includes at least a first flashing frequency, a second flashing frequency, and a third flashing frequency, wherein the first flashing frequency is less than the second flashing frequency, and the second flashing frequency is less than the third flashing frequency. The remaining power value includes at least a first remaining power value, a second remaining power value, and a third remaining power value, wherein 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 has moved to a predetermined position, if the flashing frequency of the indicator light is the first flashing frequency (10MHz), the remaining power of the charging case 100 is indicated by the first remaining power value (90%); if the flashing frequency of the indicator light is the second flashing frequency (50MHz), the remaining power of the charging case 100 is indicated by the second remaining power value (50%); and if the flashing frequency of the indicator light is the third flashing frequency (80MHz), the remaining power of the charging case 100 is indicated by the third remaining power value (20%). Therefore, the charging box 100 can characterize different parameter values ​​of the same parameter by the different flashing frequencies of the indicator light, so that the user can obtain different states of the charging box 100 according to the different flashing frequencies of the indicator light.

[0264] In some embodiments, the indicator light assembly 91 includes a plurality of indicator lights 911, which are used to emit indicator light, and the indicator light emitted by different numbers of indicator lights 911 represents different parameter values ​​of the same parameter of the charging box 100.

[0265] Specifically, the indicator light assembly 91 includes multiple indicator lights 911, and the number of indicator lights 911 is unlimited. When the cover 20 moves to a predetermined position, and the indicator light assembly 91 is in a triggered state and emits an indicator light, the number of indicator lights 911 in the triggered state and emitting indicator light can represent different parameters of the charging case 100. The parameters of the charging case 100 include, but are not limited to, the consumed power, the remaining power, and the temperature of the charging case 100. Correspondingly, the parameter values ​​include, but are not limited to, the consumed power value, the remaining power value, and the temperature value. The relationship between the number of indicator lights 911 and the parameter value of the same parameter includes, but is not limited to, positive correlation and negative correlation.

[0266] For example, in an embodiment where the parameter of the charging case 100 is temperature, the parameter value is a temperature value, and the number of indicator lights is positively correlated with the temperature, the number of indicator lights 911 emitting indicator light includes at least a first number, a second number, and a third number, wherein the first number is greater than the second number, and the second number is greater than the third number. The temperature value includes at least a first temperature value, a second temperature value, and a third temperature value, wherein 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 represents the cover 20 moving to a predetermined position, the number of indicator lights 911 emitting indicator light being the first number (e.g., 4) represents the temperature of the charging case 100 as the first temperature value (e.g., 40°C); the number of indicator lights 911 emitting indicator light being the second number (e.g., 3) represents the temperature of the charging case 100 as the second temperature value (e.g., 30°C); and the number of indicator lights 911 emitting indicator light being the third number (e.g., 2) represents the temperature of the charging case 100 as the third temperature value (e.g., 25°C). Therefore, the number of indicator lights 911 emitting indicator light in the indicator light assembly 91 can represent different parameter values ​​of the same parameter in the charging box 100, so that the user can obtain different states of the charging box 100 according to the number of indicator lights 911.

[0267] Please refer to Figures 6 and 12. In some embodiments, the indicator light assembly 91 includes a plurality of indicator lights 911, which are used to emit indicator light. The indicator light of different indicator lights 911 is used to characterize different parameters of the charging case 100.

[0268] Specifically, the indicator light assembly 91 includes multiple indicator lights 911, and the number of indicator lights 911 is unlimited. When the moving distance represents the cover 20 moving to a predetermined position, and 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 consumed, the remaining power, and the temperature of the charging case 100. Correspondingly, the parameter values ​​include, but are not limited to, the power consumed value, the remaining power value, and the temperature value. 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 (e.g., power consumed), a second parameter (e.g., remaining power), and a third parameter (e.g., temperature), wherein the first parameter, the second parameter, and the third parameter are different. In one embodiment, the indicator light emitted by the first indicator light 9111 is used to indicate the power consumed by the charging case 100, the indicator light emitted by the second indicator light 9112 is used to indicate the remaining power of the charging case 100, and the indicator light emitted by the third indicator light 9113 is used to indicate the temperature of the charging case 100. In one example, different brightness levels of the indicator light emitted by the first indicator light 9111 indicate different power consumption values ​​of the charging case 100, different colors of the indicator light emitted by the second indicator light 9112 indicate different remaining power values ​​of the charging case 100, and different flashing frequencies of the indicator light emitted by the third indicator light 9113 indicate different temperature values ​​of the charging case 100.

[0269] The indicator light assembly 91 represents different parameters of the charging box 100 through the indicator light of different indicator lights 911. Thus, the indicator light assembly 91 can convey the status of at least one charging box 100, enriching the information conveyed by the indicator light assembly 91.

[0270] In some embodiments, the indicator light assembly 91 includes a plurality of indicator lights for emitting indicator light, and the number of flashes of the indicator light of different indicator lights characterizes different parameters.

[0271] Specifically, the indicator light assembly 91 includes multiple indicator lights 911, the number of which is unlimited, and the number of flashes represents the flashing frequency. When the cover 20 moves to a predetermined position, and 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 flashing frequencies. The parameters of the charging case 100 include, but are not limited to, the power consumed, the remaining power, and the temperature of the charging case 100. Correspondingly, the parameter values ​​include, but are not limited to, the power consumed value, the remaining power value, and the temperature value.

[0272] 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 flashing frequency of the first indicator light 9111 is a first flashing frequency, the flashing frequency of the second indicator light 9112 is a second flashing frequency, and the flashing frequency of the third indicator light 9113 is a third flashing frequency, wherein the first, second, and third flashing frequencies are different. The parameters of the charging case 100 include a first parameter (e.g., consumed power), a second parameter (e.g., remaining power), and a third parameter (e.g., temperature), wherein the first, second, and third parameters are different. In one embodiment, the first flashing frequency represents the consumed power of the charging case 100, the second flashing frequency represents the remaining power of the charging case 100, and the third flashing frequency represents the temperature of the charging case 100. The indicator light assembly 91 represents different parameters of the charging case 100 by the number of flashes of the indicator light emitted by different indicator lights. Therefore, the indicator light assembly 91 can convey the state of at least one charging case 100, enriching the information conveyed by the indicator light assembly 91.

[0273] In some embodiments, the indicator light assembly 91 includes an indicator light 911 and a light guide 913. The light guide 913 covers the indicator light 911, which emits indicator light, and the light guide 913 guides the indicator light to the outside of the base 10. Thus, the light guide 913 can control the propagation direction of the indicator light, ensuring that the indicator light is emitted to a preset area and direction, thereby improving the accuracy of the indicator signal (i.e., indicator light) transmitted by the indicator light assembly 91.

[0274] Specifically, the indicator light 911 is disposed within the base 10 and electrically connected to the circuit board 120. The indicator light 911 includes, but is not limited to, LEDs, laser diodes, or other types of light-emitting elements. In one example, the indicator light assembly 911 may contain one indicator light 911. In another example, the indicator light assembly 911 may contain at least two indicator lights 911. In embodiments where there are multiple indicator lights 911, the multiple indicator lights 911 may be of the same type or different types.

[0275] The light guide 913 is at least partially located within the base 10 and covers the indicator light 911. The number of light guides 913 can be one or more, and is not limited in this application. The light guide 913 can at least change the optical path of the indicator light, thereby guiding the indicator light outside the base 10. In one example, one light guide 913 covers one indicator light 911; in another example, multiple light guides 913 cover one indicator light 911; and in yet another example, one light guide 913 covers multiple indicator lights 911. Furthermore, in other embodiments, the light guide 913 can also change parameters of the indicator light, such as its color and / or brightness.

[0276] Referring to Figure 13, in some embodiments, the central axis M of the indicator light emitted by the indicator light 911 has an angle with the central axis N of the indicator light emitted from the light guide 913.

[0277] Specifically, the light guide 913 can change the optical path of the indicator light. That is, the central axis M (i.e., the central axis of the optical path) of the indicator light emitted by the indicator light 911 and the central axis N of the indicator light emitted from the light guide 913 do not coincide and have a certain angle. The light guide 913 changes the transmission path of the indicator light emitted by the indicator light 911, making the installation of the indicator light 911 more flexible and freeing up more installation space for other components. In this embodiment, the angle between the central axis M and the central axis N is 90 degrees. In other embodiments, the angle between the central axis M and the central axis N can also be 45 degrees, 60 degrees, or 75 degrees, etc.

[0278] Furthermore, in some embodiments, the angle between the central axis M of the indicator light emitted by the indicator light 911 and the central axis N of the indicator light emitted from the light guide 913 is greater than or equal to 30° and less than or equal to 120°.

[0279] The angle between the central axis M of the indicator light emitted by the indicator light 911 and the central axis N of the indicator light emitted from the light guide 913 can be 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, or 120°. If the angle between the central axis M of the indicator light emitted by the indicator light 911 and the central axis N of the indicator light emitted from the light guide 913 is less than 30°, the light guide 913 has limited effect on changing the optical path of the indicator light, and the indicator light is not easily emitted outside the charging box 100. If the angle between the central axis M of the indicator light emitted by the indicator light 911 and the central axis N of the indicator light emitted from the light guide 913 is greater than 120°, the optical path of the indicator light emitted from the light guide 913 and the optical path of the indicator light emitted by the indicator light 911 deviates too much, which can easily cause users to misunderstand the position of the indicator light and is not conducive to users recognizing the information of the indicator light. When the angle between the central axis M of the indicator light emitted by the indicator light 911 and the central axis N of the indicator light emitted from the light guide 913 is greater than or equal to 30° and less than or equal to 120°, the light guide 913 changes the light path of the indicator light emitted by the indicator light 911. The change in angle is moderate, which is beneficial for users to identify the information of the indicator light and also makes the installation of the indicator light 911 more flexible, freeing up more installation space for other components.

[0280] Please refer to Figures 12 and 13. In some embodiments, the base 10 has a second through hole 1043 on its side wall. The light guide 913 is at least partially accommodated in the second through hole 1043. The indicator light assembly 91 has a first sealing member 56, which is sleeved on the light guide 913 and located between the inner wall of the second through hole 1043 and the outer wall of the light guide 913.

[0281] Specifically, the shape and size of the cross-section of the portion of the light guide 913 located inside the second through hole 1043, cut by a plane perpendicular to the third direction (Y1 / Y2), are approximately the same as the shape and size of the cross-section of the second through hole 1043 cut by a plane perpendicular to the third direction (Y1 / Y2). This reduces the gap between the light guide 913 and the inner wall of the second through hole 1043, reducing or even preventing external water or dust from entering the base 10 through the gap between the light guide 913 and the second through hole 1043, thereby ensuring the normal operation of the structures inside the base 10 (such as the rechargeable battery 110 and the circuit board 120).

[0282] Referring to Figures 14 and 15, the first sealing member 56 is sleeved on the light guide member 913 and is located between the outer sidewall 1711 of the light guide member 913 and the inner sidewall of the second through hole 1043, which can seal the gap between the outer sidewall 1711 of the light guide member 913 and the inner sidewall of the second through hole 1043.

[0283] The material of the first seal 56 includes, but is not limited to, metal, plastic, or rubber, and is not limited in this application. In one example, the number of first seals 56 may be one. In another example, the number of first seals 56 may be at least two. In embodiments where there are multiple first seals 56, the cross-sectional shapes of the multiple first seals 56 may be the same or different.

[0284] Therefore, when external fluid enters the second through hole 1043, the first seal 56 can block the external fluid at the part of the second through hole 1043 near the outside, preventing the external fluid from entering the base 10 through the second through hole 1043 and damaging the indicator light assembly 91, the rechargeable battery 110 and the circuit board 120, thereby ensuring the normal operation of the charging box 100.

[0285] In some embodiments, the indicator light assembly 91 includes a plurality of indicator lights 911 and a plurality of light guides 913. The plurality of light guides 913 are arranged sequentially at intervals along a moving direction perpendicular to the moving direction of the cover 20 relative to the base 10. The indicator lights and the light guides 913 are respectively arranged correspondingly in the moving direction.

[0286] Specifically, in embodiments where the indicator light assembly 91 includes multiple indicator lights 911 and multiple light guides 913, the multiple light guides 913 are arranged sequentially at intervals along a direction perpendicular to the movement of the cover 20 relative to the base 10. It should be noted that in some embodiments, the direction of movement of the cover 20 relative to the base 10 may be a first direction (Z1 / Z2); the direction of movement perpendicular to the cover 20 relative to the base 10 may include, but is not limited to, a second direction (X1 / X2) and a third direction (Y1 / Y2). This embodiment will only use the third direction (Y1 / Y2) as an example.

[0287] The spaced light guides 913 are neatly arranged and easily identifiable, improving the readability of the indicator signals emitted by the indicator light assembly 91 and providing a good visual effect. The indicator lights 911 and light guides 913 are respectively positioned correspondingly in the direction of movement, ensuring that each indicator light 911 is uniformly guided by a light guide 913. Each indicator light 911, in conjunction with its corresponding light guide 913, ensures that the indicator light propagates along a specific direction, reducing scattering and waste of the indicator light.

[0288] In some embodiments, the base 10 has a second through hole 1043 on its side wall, the indicator light assembly 91 includes a plurality of indicator lights 911, and the light guide 913 includes a plurality of light guide portions 9131 and a connecting portion 9133. The plurality of light guide portions 9131 are arranged sequentially at intervals along the moving direction perpendicular to the moving direction of the cover 20 relative to the base 10. The first end of the light guide portion 9131 is housed in the second through hole 1043, and the second ends of the plurality of light guide portions 9131 are all connected to the connecting portion 9133. The plurality of indicator lights 911 and the plurality of light guide portions 9131 are respectively arranged correspondingly in the moving direction.

[0289] Specifically, the number of light guide portions 9131, second through holes 1043, and connecting portions 9133 is not limited in this application. The number of second through holes 1043 may or may not correspond to the number of light guide portions 9131. In this application, the number of second through holes 1043 corresponds to the number of light guide portions 9131, which simplifies the assembly process of the light guide portions 9131. Each light guide portion 9131 corresponds to one second through hole 1043, which helps to isolate the indicator light from different light guide portions 9131 and reduce crosstalk and mutual interference. The first end of the light guide portion 9131 is placed inside the second through hole 1043, which can constrain the indicator light emitted from the light guide portion 9131, further controlling the direction of indicator light emission and preventing indicator light scattering. The second ends of multiple light guides 9131 are all connected to the connecting part 9133, which allows the light guide 913 formed by the light guide 9131 and the connecting part 9133 to become an integral structure, which is convenient for processing and molding. The design of connecting the light guide 9131 to the connecting part 9133 simplifies the assembly process. During installation, it is only necessary to connect the connecting part 9133 to the circuit board 120, without having to connect each light guide 9131 separately.

[0290] In some embodiments, the indicator light assembly 91 includes a plurality of indicator lights 911 and a first spacer 915. The plurality of indicator lights 911 are mounted on the circuit board 120, the first spacer 915 is mounted on the circuit board 120, and the light guide 913 is mounted on the first spacer 915. The first spacer 915 is provided with a plurality of spacer slots 9151 that are spaced apart from each other, and the plurality of indicator lights are respectively housed in different spacer slots 9151.

[0291] Specifically, there may be one or more first spacers 915; this application will describe them as one. A light guide 913 is mounted on the first spacer 915. In some embodiments, the light guide 913 and the first spacer 915 are an integral structure, which improves the bonding strength between them and prevents separation during the operation of the indicator light assembly 91, thereby ensuring the stability and reliability of the indicator light assembly 91. In other embodiments, the light guide 913 and the first spacer 915 are separate structures, i.e., they are two different structures. In one example, the light guide 913 and the first spacer 915 can be joined together using a detachable connection method, including but not limited to snap-fit ​​connections or threaded connections. In another example, the light guide 913 and the first spacer 915 can be joined together by a non-detachable connection method, including but not limited to bonding or welding.

[0292] Multiple spacer slots 9151 are spaced apart from each other, and the multiple spacer slots 9151 are not connected in the second direction (X1 / X2) or the third direction (Y1 / Y2). Thus, the indicator light emitted by the indicator lights housed in different spacer slots 9151 does not interfere with each other, and the spacer slots 9151 can prevent the indicator light from crossing each other during the process of being emitted from the indicator light to the light guide 913.

[0293] In some embodiments, the first spacer 915 is made of a light-absorbing material.

[0294] Specifically, the light-absorbing materials include, but are not limited to, black plastic and rubber. The first spacer 915 is made of light-absorbing material. The first spacer 915 can be entirely made of light-absorbing material to improve the light blocking effect and prevent light from crossing between indicator lights; or the first spacer 915 can be partially made of light-absorbing material to reduce costs while preventing light from crossing between indicator lights.

[0295] In some embodiments, the inner wall of the spacer 9151 is made of a light-absorbing material.

[0296] Specifically, the inner wall of the spacer 9151 can absorb at least part of the indicator light emitted by the indicator light, preventing some of the indicator light from entering the optical path of other indicator lights and forming stray light that affects the indicator light assembly 91 from emitting indicator signals, so as to further enhance the light blocking effect of the spacer 9151.

[0297] In some embodiments, the inner wall of the spacer 9151 is provided with a light-absorbing layer.

[0298] Specifically, the light-absorbing layer can absorb at least a portion of the indicator light emitted by the indicator light 911, preventing some indicator light from entering the optical path of other indicator lights and forming stray light that affects the indicator signal emitted by the indicator light assembly 91, thereby further enhancing the light-blocking effect of the spacer slot 9151. The light-absorbing layer can be a single layer or multiple layers. In an embodiment with multiple light-absorbing layers, the structures of different layers can have different characteristics to absorb indicator light of different wavelengths. The light-absorbing layer is easy to install and remove, and convenient to replace.

[0299] In some embodiments, the indicator light assembly 91 further includes a second spacer 917 disposed on the first spacer 915 and located at least between two adjacent light guides 913 or light guide portions 9131.

[0300] The second spacer 917 is disposed on the first spacer 915 and is located at least between two adjacent light guides 913 or light guide portions 9131. It can prevent the indicator light from crossing each other during the process of the indicator light being emitted from the light guide 913 to the base 10, thereby further preventing the indicator light exposed from the light guide 913 or light guide portion 9131 from crossing.

[0301] In some embodiments, the second spacer 917 is made of a light-absorbing material.

[0302] Specifically, the light-absorbing materials include, but are not limited to, black plastic and rubber. The second spacer 917 is made of light-absorbing material. It can be entirely made of light-absorbing material to improve the light-blocking effect and prevent light from crossing between indicator lights; or it can be partially made of light-absorbing material to reduce costs while ensuring the effect of preventing light from crossing between indicator lights.

[0303] In some embodiments, the outer wall 1711 of the second spacer 917 is provided with a light-absorbing layer.

[0304] Specifically, the light-absorbing materials include, but are not limited to, black plastic and rubber. The second spacer 917 is made of light-absorbing material. The second spacer 917 can be entirely made of light-absorbing material to improve the light-blocking effect and prevent light from crossing between indicator lights; or the second spacer 917 can be partially made of light-absorbing material to reduce costs while ensuring the effect of preventing light from crossing between indicator lights.

[0305] Referring to Figures 6 and 12, in some embodiments, the prompting component 90 is a response component 93. The state of the prompting component 90 includes a sleep state and a triggered state, and the indication signal includes an indication tone. When the movement distance indicates that the cover 20 is in the pressed position, the response component 93 is in the sleep state; when the movement distance indicates that the cover 20 has moved to a predetermined position, the response component 93 is in the triggered state and emits an indication tone to indicate the charging parameters of the charging case 100. The pressed position is the position where the cover 20 is pressed against the component to be charged placed on the base 10.

[0306] The response component 93 includes at least one prompting element, which changes its state based on the movement distance detected by the position detection component 80. In one embodiment, the indication signal emitted by the prompting element is an indication tone, and the prompting element includes, but is not limited to, a buzzer 931, a speaker, a voice chip, or other types of sound-producing elements. In one example, the response component 93 may have one prompting element. In another example, the response component 93 may have at least two prompting elements. In embodiments with multiple prompting elements, the multiple prompting elements may be of the same or different types.

[0307] For example, when the cover 20 is in the pressed position due to the movement distance, the response component 93 is in a dormant state. In the dormant state, the response component 93 does not emit an indicator sound; when the cover 20 moves from the pressed position to a predetermined position, the response component 93 switches from the dormant state to a triggered state and emits an indicator sound. In the triggered state, the parameters of the indicator sound emitted by the response component 93 include, but are not limited to, the duration, decibels, and frequency of the indicator sound. These parameters of the indicator sound reflect the parameters of the charging case 100.

[0308] Please refer to Figures 6 and 12. In some embodiments, the indicator tone has different durations, and the different durations represent different parameter values ​​of the same parameter of the charging box 100.

[0309] Specifically, the parameter of the indicator tone includes the duration of the indicator tone. When the moving distance represents the cover 20 moving to a predetermined position, and the response component 93 is in a triggered state and emits an indicator tone, the indicator tone, through different durations, represents different parameter values ​​of the same parameter of the charging case 100. At this time, the parameters of the charging case 100 include, but are not limited to, the power consumed, the remaining power, and the temperature of the charging case 100, and correspondingly, the parameter values ​​include, but are not limited to, the power consumed value, the remaining power value, and the temperature value. 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 indicator tone.

[0310] For example, in an embodiment where the parameter of the charging case 100 is the remaining battery power, the parameter value is the remaining battery power value, and the duration of the indicator tone is negatively correlated with the remaining battery power, the duration of the indicator tone includes at least a first duration, a second duration, and a third duration, wherein the first duration is less than the second duration, and the second duration is less than the third duration. The remaining battery power value of the charging case 100 includes at least a first remaining battery power value, a second remaining battery power value, and a third remaining battery power value, wherein the first remaining battery power value is greater than the second remaining battery power value, and the second remaining battery power value is greater than the third remaining battery power value. Thus, when the moving distance represents the cover 20 moving to a predetermined position, if the duration of the indicator tone is the first duration (e.g., 3 seconds), it represents the remaining battery power of the charging case 100 as the first remaining battery power value (e.g., 90%); if the duration of the indicator tone is the second duration (e.g., 5 seconds), it represents the remaining battery power of the charging case 100 as the second remaining battery power value (e.g., 80%); and if the duration of the indicator tone is the third duration (e.g., 10 seconds), it represents the remaining battery power of the charging case 100 as the third remaining battery power value (e.g., 5%). Therefore, the charging box 100 can represent different parameter values ​​of the same parameter by the different durations of the indicator sound, so that the user can obtain different states of the charging box 100 according to the different durations of the indicator sound.

[0311] Please refer to Figures 6 and 12. In some embodiments, the indicator tone has different frequencies, and the different frequencies represent different parameter values ​​of the same parameter of the charging box 100.

[0312] Specifically, the parameter of the indicator tone includes the frequency of the indicator tone. When the moving distance represents the cover 20 moving to a predetermined position, and the response component 93 is in a triggered state and emits an indicator tone, the indicator tone, through different frequencies, represents different parameter values ​​of the same parameter of the charging case 100. At this time, the parameters of the charging case 100 include, but are not limited to, the power consumed, the remaining power, and the temperature of the charging case 100, and correspondingly, the parameter values ​​include, but are not limited to, the power consumed value, the remaining power value, and the temperature value. The frequency and the different parameter values ​​of the same parameter of the charging case 100 can be positively correlated or negatively correlated.

[0313] 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 frequency of the indicator tone is negatively correlated with the remaining power, the frequency of the indicator tone includes at least a first frequency, a second frequency, and a third frequency, wherein 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, wherein 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 represents the cover 20 moving to a predetermined position, when the frequency of the indicator tone is the first frequency (20 Hz), the remaining power of the charging case 100 is represented by the first remaining power value (80%); when the frequency of the indicator tone is the second frequency (40 Hz), the remaining power of the charging case 100 is represented by the second remaining power value (60%); and when the frequency of the indicator tone is the third frequency (60 Hz), the remaining power of the charging case 100 is represented by the third remaining power value (40%). Therefore, the charging box 100 can represent different parameter values ​​of the same parameter by different frequencies of the indicator tone, so that the user can obtain different states of the charging box 100 according to the different frequencies of the indicator tone.

[0314] Referring to Figure 6, in some embodiments, the response component 93 includes a plurality of buzzers 931 for emitting indicator tones, and the indicator tones emitted by different numbers of buzzers 931 represent different parameter values ​​of the same parameter of the charging box 100.

[0315] Specifically, the response component 93 includes multiple buzzers 931, and the number of buzzers 931 is unlimited. When the cover 20 moves to a predetermined position, and the response component 93 is in a triggered state and emits an indicator tone, the response component 93 can characterize different parameters of the charging case 100 by the number of buzzers 931 in the triggered state emitting the indicator tone. The parameters of the charging case 100 include, but are not limited to, the consumed power, the remaining power, and the temperature of the charging case 100. Correspondingly, the parameter values ​​include, but are not limited to, the consumed power value, the remaining power value, and the temperature value. The relationship between the number of buzzers 931 and the parameter value of the same parameter includes, but is not limited to, positive correlation and negative correlation.

[0316] For example, in an embodiment where the parameter of the charging case 100 is temperature, the parameter value is a temperature value, and the number of buzzers 931 is positively correlated with the temperature, the number of buzzers 931 emitting an indicator tone includes at least a first number, a second number, and a third number, wherein the first number is greater than the second number, and the second number is greater than the third number. The temperature value includes at least a first temperature value, a second temperature value, and a third temperature value, wherein 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 represents the cover 20 moving to a predetermined position, the number of buzzers 931 emitting an indicator tone being the first number (e.g., 4) represents the temperature of the charging case 100 being the first temperature value (e.g., 40°C); the number of buzzers 931 emitting an indicator tone being the second number (e.g., 3) represents the temperature of the charging case 100 being the second temperature value (e.g., 30°C); and the number of buzzers 931 emitting an indicator tone being the third number (e.g., 2) represents the temperature of the charging case 100 being the third temperature value (e.g., 25°C). Therefore, the charging box 100 can characterize different parameter values ​​of the same parameter by the number of buzzers 931 in the response component 93 that are in the triggered state and emit indicator light, so that the user can obtain different states of the charging box 100 according to the number of buzzers 931.

[0317] Referring to Figure 5, in some embodiments, the response component 93 includes a plurality of buzzers 931, which are used to emit indicator sounds. The indicator sounds of different buzzers 931 are used to characterize different parameters of the charging case 100.

[0318] Specifically, the response component 93 includes multiple buzzers 931, and the number of buzzers 931 is unlimited. When the moving distance represents the cover 20 moving to a predetermined position, and the response component 93 is in a triggered state and emits an indicator tone, different indicator tones can represent different parameters of the charging case 100. The parameters of the charging case 100 include, but are not limited to, the power consumed, the remaining power, and the temperature of the charging case 100. Correspondingly, the parameter values ​​include, but are not limited to, the power consumed value, the remaining power value, and the temperature value. When different indicator tones represent the parameters of the charging case 100, the parameters of the indicator tones 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 (e.g., power consumed), a second parameter (e.g., remaining power), and a third parameter (e.g., temperature), wherein the first parameter, the second parameter, and the third parameter are different. In one embodiment, the indicator tone emitted by the first buzzer 931 is used to represent the power consumed by the charging case 100, the indicator tone emitted by the second buzzer 931 is used to represent the remaining power of the charging case 100, and the indicator tone emitted by the third buzzer 931 is used to represent the temperature of the charging case 100. In one example, different durations of the indicator tone emitted by the first buzzer 931 represent different power consumption values ​​of the charging case 100, different frequencies of the indicator tone emitted by the second buzzer 931 represent different remaining power values ​​of the charging case 100, and different decibels of the indicator tone emitted by the third buzzer 931 represent different temperature values ​​of the charging case 100. The response component 93 represents different parameters of the charging case 100 through the indicator tones of different buzzers 931, thereby enabling the response component 93 to convey the state of at least one charging case 100, enriching the information conveyed by the response component 93.

[0319] Please refer to Figures 3 and 14. In some embodiments, the base 10 is provided with a third through hole 1045. The charging box 100 also includes a data exchange terminal 901 and a second sealing member 57. The second sealing member 57 is sleeved on the data exchange terminal 901 and located between the outer sidewall 1711 of the data exchange terminal 901 and the inner sidewall of the third through hole 1045. The second sealing member 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.

[0320] Specifically, the shape and size of the cross-section of the data exchange terminal 901 cut by a plane perpendicular to the third direction (Y1 / Y2) are approximately the same as the shape and size of the cross-section of the third through hole 1045 cut by a plane perpendicular to the third direction (Y1 / Y2). This reduces the gap between the data exchange terminal 901 and the inner wall of the third through hole 1045, reducing or even preventing external water or dust from entering the base 10 through the gap between the data exchange terminal 901 and the third through hole 1045, thereby ensuring the normal operation of the structures inside the base 10 (such as the rechargeable battery 110 and the circuit board 120).

[0321] The second sealing element 57 is sleeved on the data exchange terminal 901 and located between the outer wall of the data exchange terminal 901 and the inner wall of the second through hole 1043, sealing the gap between the outer wall of the data exchange terminal 901 and the inner wall of the second through hole 1043. Therefore, when external fluid enters the third through hole 1045, the second sealing element 57 can block the external fluid at the portion of the third through hole 1045 near the outside, preventing external fluid from entering the base 10 through the third through hole 1045 and damaging structures such as the rechargeable battery 110 and circuit board 120, thus ensuring the normal operation of the charging box 100.

[0322] Please refer to Figures 3, 14, 16, and 17. In some embodiments, the base 10 is provided with a fourth through hole 1047. The first electrical connector 17 includes a charging terminal 171, one end of which is located inside the base 10, and the other end of which extends out of the fourth through hole 1047 to the outside of the base 10. The charging box 100 also includes a third seal 58, which is disposed between the inner wall of the fourth through hole 1047 and the outer wall 1711 of the charging terminal 171. The third seal 58 is used to prevent fluid from entering the base 10 from between the inner wall of the fourth through hole 1047 and the outer wall 1711 of the charging terminal 171.

[0323] The fourth through-hole 1047 connects the interior and exterior of the charging case 100. The fourth through-hole 1047 is located 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 polygonal, and is not limited thereto. In one example, there may be one fourth through-hole 1047, in which a charging terminal 171 is installed. In another example, there may be at least two fourth through-holes 1047, in which case one charging terminal 171 is installed in each fourth through-hole 1047. This increases the density of the charging terminals 171 and improves the electrical connection stability of the charging case 100 assembly.

[0324] Referring to Figure 2, the charging terminal 171 is installed within the fourth through hole 1047 to achieve 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 extends from the fourth through hole 1047 to the outside of the base 10. The end of the charging terminal 171 located outside the base 10 is used to connect to the second electrical connector 280 to achieve electrical connection with the earphone 200, and the 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 into the fourth through hole 1047 is the first direction (Z1 / Z2).

[0325] There is a certain difference in size between the fourth through hole 1047 and the charging terminal 171, which serves as a reserve size for installation, allowing the charging terminal 171 to be installed inside 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 wall of the fourth through hole 1047 and the outer wall 1711 of the charging terminal 171.

[0326] The third sealing element 58 is disposed between the fourth through hole 1047 and the charging terminal 171, and is used to seal the gap between the inner wall of the fourth through hole 1047 and the outer wall 1711 of the charging terminal 171 to prevent fluid from flowing into the charging box 100 through the gap. The third sealing element 58 can be made of various materials such as rubber, silicone, and polypropylene. There can be one or more third sealing elements 58, which is not limited in this application. In the embodiments of this application, the number of third sealing elements 58, the number of charging terminals 171, and the number of fourth through holes 1047 are in a one-to-one correspondence.

[0327] The third sealing element 58 can be molded separately and then fitted onto the charging terminal 171, or it can be fitted onto the outer wall 1711 of the charging terminal 171 in the form of encapsulation, or it can be directly molded onto the outer wall 1711 of the charging terminal 171 through a two-color injection molding process. In this case, the materials of the charging terminal 171 and the third sealing element 58 can be the same or different.

[0328] The third seal 58 is installed in the gap between the inner wall of the fourth through hole 1047 and the outer wall 1711 of the charging terminal 171 in the charging case 100. It seals the gap between the inner wall of the fourth through hole 1047 and the outer wall 1711 of the charging terminal 171, preventing fluid from flowing into the charging case 100 and improving the waterproof rating of the charging case 100. Furthermore, the third seal 58 is low-cost and does not occupy additional installation space.

[0329] In some embodiments, the third seal 58 and the charging terminal 171 are separate structures. The third seal 58 is sleeved on the outer side wall 1711 of the charging terminal 171 and is located between the outer side wall 1711 of the charging terminal 171 and the inner side wall of the fourth through hole 1047.

[0330] The third seal 58 and the charging terminal 171 are separate structures, meaning they are two distinct components. In one example, the third seal 58 and the charging terminal 171 can be detachably connected, including but not limited to snap-fit ​​connections or threaded connections. In another example, the third seal 58 and the charging terminal 171 can be non-detachably connected, including but not limited to adhesive bonding or welding. This separate structure facilitates the replacement of both the third seal 58 and the charging terminal 171.

[0331] In some embodiments, the third seal 58 is a sealing ring.

[0332] 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 wall 1711 of the charging terminal 171 to seal the gap between the inner wall of the fourth through hole 1047 and the outer wall 1711 of the charging terminal 171. The sealing ring is easy to replace and has low cost.

[0333] The sealing ring can be made of a material with a certain degree of elasticity, such as rubber. Rubber materials include, but are not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber. The elastic sealing ring not only provides waterproofing but also absorbs vibration and impact for the charging terminal 171, preventing deformation of the charging terminal 171 under external forces.

[0334] In some embodiments, the third seal 58 is an integral structure with the charging terminal 171.

[0335] Specifically, the third seal 58 and the charging terminal 171 are an integral structure, that is, the third seal 58 and the charging terminal 171 are an integral structure, which can improve the bonding strength between the third seal 58 and the charging terminal 171, prevent the third seal 58 and the charging terminal 171 from separating during the operation of the charging box 100, thereby ensuring the stability and reliability of the operation of the charging box 100, and further improving the sealing and waterproof effect.

[0336] In some embodiments, both the third seal 58 and the charging terminal 171 are made of metal.

[0337] Specifically, metals have high strength and good wear resistance, and using metal as the material for the third seal 58 and the charging terminal 171 can extend the service life of both. In embodiments 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 is understood that the material of the charging terminal 171 can be a material with good 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 resistance and will not be corroded by impurities in water, thus ensuring the waterproof effect of the third seal 58.

[0338] In embodiments where the third seal 58 and the charging terminal 171 are integrally formed and both the third seal 58 and the charging terminal 171 are made of metal, the integrally formed and metal third seal 58 and the charging terminal 171 can form an interference fit with the fourth through hole 1047, thereby sealing the gap between the outer sidewall 1711 of the charging terminal 171 and the inner sidewall of the fourth through hole 1047, achieving a waterproof effect.

[0339] In the embodiment where the third sealing element 58 and the charging terminal 171 are integrally formed and both the third sealing element 58 and the charging terminal 171 are made of copper, the integrally formed and copper-made third sealing element 58 and the charging terminal 171 can not only form an interference fit with the fourth through hole 1047, thereby sealing the gap between the outer side wall 1711 of the charging terminal 171 and the inner side wall of the fourth through hole 1047 to achieve a waterproof effect, but also copper has strong conductivity and strong rust resistance, and will not be corroded by impurities in water. This not only ensures the waterproof effect, but also ensures the stability of the connection between the charging terminal 171 and the second electrical connector 280.

[0340] In some embodiments, the first electrical connector 17 includes an electrical connector 173, which is mounted on the circuit board 120 (received in the base 10) and electrically connected to the charging terminal 171. It should be noted that in some embodiments, each first electrical connector 17 includes a charging terminal 171 and an electrical connector 173.

[0341] Electrical connector 173 connects charging terminal 171 to circuit board 120. There can be one or more electrical connectors 173. One electrical connector 173 can correspond to multiple charging terminals 171, 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 embodiment 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, or nickel. The electrical connector 173 has a certain elastic deformation capability, capable of elastic deformation in a first direction (Z1 / Z2), thereby better connecting the charging terminal 171 and circuit board 120. When the charging terminal 171 is inserted into the fourth through hole 1047, the charging terminal 171 applies a force in the first direction (Z1 / Z2) to the electrical connector 173. The electrical connector 173 can elastically deform according to the insertion depth of the charging terminal 171 in the first direction (Z1 / Z2) (i.e., the distance between the charging terminal 171 and the circuit board 120), thereby allowing the electrical connector 173 to better fit with the charging terminal 171. That is, the electrical connector 173 can adjust its elastic deformation degree according to the distance between the charging terminal 171 and the circuit board 120, thereby ensuring the stability of the electrical connection between the charging terminal 171 and the circuit board 120.

[0342] After the charging terminal 171 is installed into the fourth through hole 1047, if the charging terminal 171 is subjected to a force in the first direction (Z1 / Z2) and moves towards the circuit board 120, the electrical connector 173 can provide an opposite force and isolate the charging terminal 171 and the circuit board 120, preventing the charging terminal 171 from directly pressing the circuit board 120 and causing damage to the circuit board 120. After the charging terminal 171 is installed into the fourth through hole 1047, if the charging terminal 171 is subjected to a force opposite to the first direction (Z1 / Z2), causing the distance between the charging terminal 171 and the circuit board 120 in the first direction (Z1 / Z2) to increase, the electrical connector 173 can recover some of its elastic deformation and continue to maintain an electrical connection with the charging terminal 171, thereby ensuring the stability of the electrical connection between the charging terminal 171 and the circuit board 120.

[0343] Electrical connector 173 is mounted on circuit board 120 and electrically connected to charging terminal 171. Electrical connector 173 can adapt to different distances between charging terminal 171 and circuit board 120 through elastic deformation, thereby maintaining a stable electrical connection between charging terminal 171 and circuit board 120. Furthermore, using electrical connector 173 avoids the need for SMT (Surface Mount Technology) processes to connect charging terminal 171 and circuit board 120, saving costs.

[0344] In some embodiments, the electrical connector 173 includes a conductive body 1731 and a conductive spring 1733. The conductive body 1731 is mounted on the circuit board 120. The conductive spring 1733 extends from the conductive body 1731 in a direction away from the circuit board 120 and then bends back in a direction close to the circuit board 120 to form a protrusion. The protrusion abuts against the engaging portion 613 of the charging terminal 171.

[0345] Specifically, the conductive spring 1733 has a certain elastic deformation capability, and can elastically deform in the first direction (Z1 / Z2) to better contact the charging terminal 171, thereby better connecting the charging terminal 171 and the circuit board 120. The conductive body 1731 is mounted on the circuit board 120, which can ensure a stable connection between the electrical connector 173 and the circuit board 120, making it difficult for the electrical connector 173 to fall off the circuit board 120.

[0346] In the embodiments of this application, the conductive body 1731 and the conductive spring 1733 are an integral structure, that is, the conductive body 1731 and the conductive spring 1733 are a single unit. This improves the bonding strength between the conductive body 1731 and the conductive spring 1733, preventing separation of the conductive body 1731 and the conductive spring 1733 during the operation of the electrical connector 173, thereby ensuring the stability and reliability of the electrical connector 173. In other embodiments, the conductive body 1731 and the conductive spring 1733 are separate structures, that is, the conductive body 1731 and the conductive spring 1733 are two different structures.

[0347] In one example, the conductive body 1731 and the conductive spring 1733 can be detachably connected, including but not limited to snap-fit ​​connections or threaded connections. In another example, the conductive body 1731 and the conductive spring 1733 can be non-detachably connected, including but not limited to bonding or welding. The protrusion abuts against the charging terminal 171 and has a certain degree of elasticity; that is, the conductive spring 1733 can elastically deform in the first direction (Z1 / Z2) to change its relative position with the charging terminal 171, adapting to different relative positions to ensure electrical connection with the charging terminal 171, thereby making the connection between the electrical connector 173 and the charging terminal 171 more stable.

[0348] In some embodiments, the outer surface of the top wall of the base 10 is curved, there are multiple charging terminals 171 and multiple electrical connectors 173, and at least two electrical connectors 173 have different contact positions with the corresponding charging terminals 171 at different heights relative to the circuit board 120, so that the outer surfaces of the multiple charging terminals 171 are flush.

[0349] Specifically, in some embodiments, the outer surface of the base 10 is curved, that is, the outer surface of the base 10 is not planar, which allows the outer surface of the base 10 to adapt to different environments, such as adapting to headphones 200 with different shapes and contours. The outer surfaces of the multiple charging terminals 171 are flush, which allows for good electrical connection with the second electrical connector 280 on the headphones 200. Furthermore, the distance between the outer surfaces of the multiple charging terminals 171 and the outer surface of the base 10 is the same, which allows the outer surfaces of the multiple charging terminals 171 to be flat, avoiding the charging terminals 171 from protruding and being bumped.

[0350] Please refer to Figure 14. In some embodiments, the top of the base body 111 is provided with a fifth through hole 1049, and the top cover 113 is provided on the fifth through hole 1049. The charging box 100 also includes a fourth sealing member 59, which is disposed on the top of the base body 111 and located between the base body 111 and the top cover 113. The fourth sealing member 59 is used to seal the gap between the base body 111 and the top cover 113.

[0351] The base body 111 and the top cover 113 can be joined together by a detachable connection method, including but not limited to snap-fit ​​connections or threaded connections. In another example, the base body 111 and the top cover 113 can be joined together by a non-detachable connection method, including but not limited to adhesive bonding or welding.

[0352] The fourth sealing element 59 is disposed on the top of the base body 111 and located between the base body 111 and the upper cover 113. Therefore, when external fluid enters the fifth through hole 1049, the fourth sealing element 59 can block the external fluid from entering the base 10 through hole 1049 and preventing it from damaging the rechargeable battery 110 and circuit board 120, thus ensuring the normal operation of the charging box 100.

[0353] In some embodiments, the fourth seal 59 is a sealing ring.

[0354] Specifically, in the embodiment where the fourth seal 59 is formed separately, the fourth seal 59 can be a sealing ring. The fourth seal 59 is disposed on the top of the seat body 111 and 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. The sealing ring is easy to replace and has low cost.

[0355] The sealing ring can be made of a material with a certain degree of elasticity, such as rubber. Rubber materials include, but are not limited to, natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber, or silicone rubber. The elastic sealing ring not only provides waterproofing but also absorbs vibration and impact for the charging terminal 171, preventing deformation of the charging terminal 171 under external forces.

[0356] In some embodiments, the fourth seal 59 is a sealant. Specifically, in embodiments where the fourth seal 59 is a sealant, the sealant is easy to apply. After the sealant is applied directly to the seat body 111 and / or the top cover 113, the seat body 111 and the top cover 113 can be directly closed and connected without an alignment process, making installation simple.
