Charging box and earphone system

Abstract

The utility model discloses a charging box and an earphone system. The charging box comprises a base, a cover body and a limiting assembly. The cover body is connected with the base and can ascend and descend relative to the base so as to selectively release or compress the to-be-charged part. The limiting assembly is arranged on the cover body and / or the base and used for limiting the lifting stroke of the cover body relative to the base. In the charging box and the earphone system provided by the embodiment of the invention, the arrangement of the limiting assembly can limit the lifting stroke of the cover body relative to the base, so that the situation that the cover body continuously descends under the acting force generated by collision of the charging box when the charging box falls off, and the cover body generates overlarge impact force on the base can be avoided; therefore, the possibility that the charging box is damaged can be reduced, and the service life of the charging box is prolonged.

Description

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 to charge or store devices such as earphones. For example, when a device's battery is low or it is no longer needed, the user can place it in the charging case. The charging case includes a base and a lid, with the lid capable of lifting relative to the base for easy placement and removal of the earphones. However, if the lid's lifting range relative to the base is unrestricted, in the event of a drop, the lid may continue to descend under the impact force, causing excessive impact on the base and potentially damaging the charging case, thus affecting its lifespan. Utility Model Content

[0003] The charging case provided in this application includes a base, a cover, and a limiting component. The cover is connected to the base and can be raised and lowered relative to the base to selectively release or press the component to be charged. The limiting component is disposed on the cover and / or the base, and is used to limit the lifting stroke of the cover relative to the base.

[0004] In some embodiments, the limiting component includes a limiting member and a locking member, one of which is disposed on the inner wall of the base and the other is disposed on the outer wall of the cover. The limiting member and the locking member cooperate to limit the upward and downward travel of the cover relative to the base.

[0005] In some embodiments, the limiting member includes a first limiting member and a second limiting member, which are spaced apart along the lifting direction of the cover. The first limiting member is closer to the bottom of the base than the second limiting member, and the locking member is located between the first and second limiting members. When the first limiting member cooperates with the locking member, the limiting component restricts the upward travel of the cover relative to the base; when the second limiting member cooperates with the locking member, the limiting component restricts the downward travel of the cover relative to the base.

[0006] In some embodiments, when the cover is in the released position, the locking member abuts against the first limiting member.

[0007] In some embodiments, when the cover is in the pressed position, the locking member abuts against the second limiting member.

[0008] In some embodiments, the limiting component further includes a buffer. The buffer is disposed on the first limiting member and / or the locking member, and when the cover is in the released position, the buffer is located between the first limiting member and the locking member.

[0009] In some embodiments, the limiting component further includes a buffer. The buffer is disposed on the second limiting member and / or the locking member, and when the cover is in the pressed position, the buffer is located between the second limiting member and the locking member.

[0010] In some embodiments, the cushioning element is made of at least one of silicone, rubber, resin, and polyurethane.

[0011] In some embodiments, when the limiting member is disposed on the inner wall of the base and the locking member is disposed on the outer wall of the cover, the limiting member and the base are an integral structure or a separate structure, and the locking member and the cover are an integral structure or a separate structure.

[0012] In some embodiments, when the locking member is disposed on the inner wall of the base and the limiting member is disposed on the outer wall of the cover, the locking member and the base are an integral structure or a separate structure, and the limiting member and the cover are an integral structure or a separate structure.

[0013] In some embodiments, the cover includes a main body and an extension, the extension extending from the main body toward the base, the base including a seat and a connector, the connector extending from the seat toward the cover, the extension partially extending into the connector and capable of rising and falling relative to the connector, one of the limiting member and the locking member being disposed on the inner wall of the connector, and the other being disposed on the outer wall of the extension.

[0014] In some embodiments, the extension is disposed on the side edge of the body, and the connector is disposed on the side edge of the seat.

[0015] The headphone system provided in this application includes headphones and a charging case as described in any of the above embodiments, wherein the charging case is used to charge the headphones.

[0016] 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 continuing to fall under the force generated by the collision of the charging case when it falls, which would cause the cover to generate excessive impact force on the base, thereby reducing the possibility of damage to the charging case and extending the service life of the charging case.

[0031] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0032] In the description of this application, it should be understood that the terms "thickness," "upper," "top," "bottom," "inner," "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. 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.

[0033] 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.

[0034] Please see Figure 1 The headphone system 300 provided in this embodiment includes headphones 200 and a charging case 100. The charging case 100 is used to charge the headphones 200. Since the headphone system 300 in this embodiment includes the charging case 100, it is understood that the headphone system 300 includes at least the same beneficial effects as the charging case 100. Therefore, the beneficial effects of the headphone system 300 are described below in relation to the beneficial effects of the charging case 100.

[0035] In some embodiments of this application, the earphone 200 can be worn on a user's ear and can be used in conjunction 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. Specifically, in some embodiments, the earphone 200 includes air-conduction earphones and bone-conduction earphones. Air-conduction earphones, also known as air-conduction headphones, are earphones that transmit sound through air vibrations. Bone-conduction earphones, also known as bone-conduction headphones, are earphones that convert sound into different mechanical vibrations and transmit sound waves through the skull, bony labyrinth, inner ear synovial fluid, cochlea, and auditory center.

[0036] 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.

[0037] 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 200 as an example.

[0038] 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.

[0039] Please see Figure 1 and Figure 4In some embodiments, the charging case 100 includes a rechargeable battery 110 and a charging circuit. When the earphone 200 is placed in the charging case 100, the charging circuit can deliver electrical energy from the rechargeable battery 110 to the earphone 200 to charge the earphone 200.

[0040] Furthermore, please combine Figure 2 and Figure 3 In some embodiments, the charging case 100 is provided with a first electrical connector 15, and the earphone 200 is provided with a second electrical connector 270. When the earphone 200 is placed in the charging case 100, the first electrical connector 15 and the second electrical connector 270 are electrically connected.

[0041] Specifically, in some embodiments, when the first electrical connector 15 and the second electrical connector 270 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 15 and the second electrical connector 270 are electrically connected, the charging circuit can transmit the electrical energy of the rechargeable battery 110 to the battery compartment 220 of the earphone 200 through the first electrical connector 15 and the second electrical connector 270, thereby charging the earphone 200. It should be noted that in some embodiments, the first electrical connector 15 can be at least one of the devices that can achieve electrical connection, such as a spring pin and a spring sheet; the second electrical connector 270 can be a device that can be electrically connected to the first electrical connector 15.

[0042] Furthermore, in some embodiments, the first electrical connector 15 includes a plurality of components, and the second electrical connector 270 includes a plurality of components. When the earphone 200 is placed in the charging case 100, the plurality of first electrical connectors 15 and the plurality of second electrical connectors 270 are electrically connected in a one-to-one correspondence.

[0043] Specifically, in some embodiments, a portion of the plurality of first electrical connectors 15 is used for power transmission, and another portion is used for signal transmission; correspondingly, a portion of the plurality of second electrical connectors 270 is used for power transmission, and another portion is used for signal transmission. The plurality of first electrical connectors 15 are arranged side-by-side on the charging case 100. This arrangement, compared to a non-side-by-side arrangement, reduces the space occupied by the first electrical connectors 15, making the structure more compact and facilitating the miniaturization of the charging case 100. Furthermore, it facilitates the alignment of the first electrical connectors 15 and the second electrical connectors 270, improving the convenience of electrical connection.

[0044] Please see Figure 1 , Figure 3 and Figure 4The charging case 100 provided in this application includes a base 10, a cover 20, and a limiting component 30. The cover 20 is connected to the base 10 and can be raised and lowered relative to the base 10 to selectively release or press the component to be charged. The limiting component 30 is disposed on the cover 20 and / or the base 10, and is used to limit the lifting stroke of the cover 20 relative to the base 10. It should be noted that in some embodiments, the component to be charged may be the earphone 200 in the above embodiments.

[0045] The base 10 is a structure in the charging case 100 used to support the earphones 200. In some embodiments of this application, both the rechargeable battery 110 and the charging circuit 120 are disposed in the base 10, which makes the base 10 relatively heavy 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.

[0046] 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.

[0047] Please combine Figure 4 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.

[0048] The pressing position can be: along the lifting direction of the cover 20 (same as the height direction Z 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.

[0049] 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 270) and the charging terminal of the charging case 100 (i.e., the first electrical connector 15), 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.

[0050] 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.

[0051] 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 continuing to descend under the force generated by the collision of the charging case 100 when the charging case 100 falls, which would cause the cover 20 to generate excessive impact force on the base 10, thereby reducing the possibility of damage to the charging case 100 and extending the service life of the charging case 100.

[0052] 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.

[0053] The charging case 100 will be further explained below with reference to the accompanying drawings.

[0054] Please see Figure 3 and Figure 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.

[0055] Specifically, in some embodiments, the connector 13 may be provided with a movable space, and a portion of the extension 23 can extend into the movable space and 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 shifting and jamming during lifting and lowering, thereby improving the stability of the cover 20 lifting and lowering relative to the base 10.

[0056] It is understood that the projection of the extension 23 on the base 11 is located inside the connector 13, thereby ensuring that part of the extension 23 can extend into the connector 13, and thus enabling the extension 23 to rise and fall relative to the connector 13.

[0057] 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.

[0058] Furthermore, in some embodiments, both the rechargeable battery 110 and the charging circuit 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 charging circuit 120 within the base 11.

[0059] Please combine Figure 1 In some embodiments, the cover 20 and the base 10 together form an earphone compartment 101 for accommodating earphones 200.

[0060] Specifically, in some embodiments, the main body 21, extension 23, connector 13, and 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 Z 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 Z 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.

[0061] 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.

[0062] Specifically, in some embodiments, in the direction perpendicular to the height direction Z 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 of the earphone compartment), thereby enabling the charging case 100 to charge and store the earphones 200.

[0063] 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.

[0064] 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.

[0065] Please see Figure 3 and Figure 4 In some embodiments, the limiting component 30 includes a limiting member 31 and a locking member 33. One of the limiting member 31 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 31 and the locking member 33 cooperate to limit the upward and downward travel of the cover 20 relative to the base 10. It should be noted that, in some embodiments, one of the limiting member 31 and the locking member 33 being disposed on the inner wall of the base 10 and the other being disposed on the outer wall of the cover 20 means that one of the limiting member 31 and the locking member 33 being disposed on the inner wall of the connecting member 13 and the other being disposed on the outer wall of the extension member 23.

[0066] Specifically, in some embodiments, the limiting member 31 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 31 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.

[0067] In some embodiments, the limiting member 31 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 31 is disposed on the connector 13, and the locking member 33 is disposed on the extension 23.

[0068] Furthermore, in some embodiments, when the limiting member 31 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 31 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.

[0069] Specifically, the limiting member 31 and the base 10 are an integral structure, meaning that the limiting member 31 and the connecting member 13 can be integrally molded to form a whole. This improves the connection strength between the limiting member 31 and the connecting member 13, preventing the limiting member 31 from detaching from the connecting member 13 when it engages with the locking member 33, thus ensuring the stability and reliability of the limiting assembly 30. Alternatively, the limiting member 31 and the base 10 can be separate structures, meaning that the limiting member 31 and the connecting member 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.

[0070] 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 31 and the base 10, and will not be described again here.

[0071] In other embodiments, the limiting member 31 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 31 is disposed on the extension member 23, and the locking member 33 is disposed on the connector 13.

[0072] Furthermore, in some embodiments, when the locking member 33 is disposed on the inner wall of the base 10 and the limiting member 31 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 31 and the cover 20 are an integral structure or a separate structure.

[0073] Specifically, the limiting member 31 and the cover 20 are an integral structure, meaning that the limiting member 31 and the extension member 23 can be integrally molded to form a whole. This improves the connection strength between the limiting member 31 and the extension member 23, preventing the limiting member 31 from falling off the extension member 23 when it engages with the locking member 33, thus ensuring the stability and reliability of the limiting assembly 30. Alternatively, the limiting member 31 and the cover 20 can be separate structures, meaning that the limiting member 31 and the extension member 23 are two different structures, and they can be connected by 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.

[0074] 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 31 and the cover 20, and will not be described again here.

[0075] In the embodiments described below, the example is that the limiting member 31 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.

[0076] Please see Figure 4 In some embodiments, the limiting member 31 may include two, and correspondingly, the locking member 33 also includes two. The two limiting members 31 are respectively disposed on opposite sides of the extension member 23 in the height direction Z 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 31. Thus, compared to having only one limiting member 31, the setting of two limiting members 31 can improve the stability of the cooperation between the limiting member 31 and the locking member 33, and avoid the problem that the cover 20 is tilted relative to the base 10 due to only one side being subjected to force (one side being limited) during the lifting and lowering process 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 improves the stability and reliability of the charging box 100.

[0077] Please continue reading Figure 4 In some embodiments, the limiting member 31 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.

[0078] 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 of the connector 13 is provided with a protrusion, which extends from the inner wall of the connector 13 toward the center of the connector 13, and the protrusion is formed as the locking member 33. Wherein, 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 rising and falling strokes of the cover 20 relative to the base 10.

[0079] 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 of the connector 13 is provided with a protrusion, which protrudes from the inner wall 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.

[0080] Please combine 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] More specifically, please combine Figure 1 In some embodiments, when the cover 20 is in the released position, the locking member 33 abuts against the first limiting member 311. In this 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 this case, the cover 20 can press the earphone 200, that is, the earphone 200 can be pressed into the earphone compartment 101.

[0085] Please see Figure 4 and Figure 5 In some embodiments, the limiting component 30 further includes a buffer 50. The buffer 50 is disposed on the first limiting component 311 and / or the locking component 33, and when the cover 20 is in the released position, the buffer 50 is located between the first limiting component 311 and the locking component 33.

[0086] The buffer 50 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 component 30 and ensuring the stability and reliability of the charging box 100. It should be noted that in some embodiments, the buffer 50 is made of at least one of silicone, rubber, resin, and polyurethane.

[0087] In some embodiments, the buffer member 50 is disposed on the side of the first limiting member 311 opposite to the locking member 33. In other embodiments, the buffer member 50 is disposed on the side of the locking member 33 opposite to the first limiting member 311. In still other embodiments, the buffer member 50 includes two buffer members 50, with the two buffer members 50 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.

[0088] In some embodiments, the buffer member 50 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 buffer member 50 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 buffer member 50 and the locking member 33 is basically the same as the connection method between the buffer member 50 and the first limiting member 311, and will not be described again here.

[0089] In some embodiments, the buffer 50 is disposed on the second limiting member 313 and / or the locking member 33. When the cover 20 is in the pressed position, the buffer 50 is located between the second limiting member 313 and the locking member 33. The buffer 50 prevents the second limiting member 313 from rigidly colliding with the locking member 33 and causing damage, thereby extending the service life of the limiting assembly 30 and ensuring the stability and reliability of the charging box 100.

[0090] In some embodiments, the buffer member 50 is disposed on the side of the second limiting member 313 opposite to the locking member 33. In other embodiments, the buffer member 50 is disposed on the side of the locking member 33 opposite to the second limiting member 313. In still other embodiments, the buffer member 50 includes two buffer members 50, each disposed on the side of the second limiting member 313 opposite to the locking member 33 and the side of the locking member 33 opposite to the second limiting member 313, respectively.

[0091] It is understandable that the connection between the buffer 50 and the second limiting member 313 is basically the same as the connection between the buffer 50 and the first limiting member 311, and will not be described again here.
