Description

Technical Field

[0001] This application relates to the field of electronic device technology, and more specifically, to a damping element, a charging case, and an 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 moving relative to the base to open and close the case. The lid and base usually employ a gap fit to improve the smoothness of the lid's movement relative to the base. However, a gap between the lid and base can lead to poor stability during lid movement and an unpleasant tactile experience. Utility Model Content

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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] Please combine Figure 4 In some embodiments, the charging case 100 includes a rechargeable battery 110 and a charging circuit 120. When the earphone 200 is placed in the charging case 100, the charging circuit 120 can deliver electrical energy from the rechargeable battery 110 to the earphone 200 to charge the earphone 200.

[0043] 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.

[0044] 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 120 can transmit the electrical energy of the rechargeable battery 110 to the battery compartment 220 of the earphone 200 through the first electrical connector 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.

[0045] 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.

[0046] 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.

[0047] Please see Figure 4 The charging case 100 provided in this embodiment includes a base 10, a cover 20, and a damping member 30. The base 10 includes a connector 13. The cover 20 is movably connected to the base 10 and includes an extension 23, which partially extends into the connector 13 and is clearance-fitted with the connector 13. The damping member 30 is used to restrict the degree of freedom of the extension 23 in the horizontal direction, which is perpendicular to the height direction Z of the charging case 100.

[0048] Since the charging box 100 in this embodiment includes a damping element 30, it is understood that the charging box 100 has at least the same beneficial effects as the damping element 30. Therefore, for the beneficial effects of the charging box 100, please refer to the beneficial effects of the damping element 30 described below.

[0049] Specifically, the base 10 is the structure in the charging case 100 used to support the earphones. 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 of this application, the base 10 also includes a seat 11, and a connector 13 extends from the seat 11 toward the cover 20. The rechargeable battery 110 and the charging circuit 120 are both disposed in the seat 11, which makes the base 10 heavier and reduces the possibility of the charging case 100 tipping over when the earphones are stored in it. The connector 13 may have a movable space, and a portion of the extension 23 can extend into the movable space and fit with the inner wall 131 of the connector with a clearance, so that the extension 23 can move relative to the connector 13 within the movable space.

[0050] The cover 20 is a structure in the charging case 100 that can cooperate with the base 10 to restrict the earphones. 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. In some embodiments of this application, the cover 20 also includes a main body 21, and an extension 23 extends from the main body 21 toward the base 10. 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. The main body 21 and the extension 23 can be connected together using a detachable or non-detachable connection method. The detachable connection methods include, but are not limited to, snap-fit ​​connections or bolt connections; the non-detachable connection methods include, but are 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 again here.

[0051] A movable connection refers to a connection method between two or more components that allows relative movement between the connected components. In this case, the cover 20 and the base 10 are movably connected, meaning that the cover 20 and the base 10 can rotate, slide, or lift relative to each other. In some embodiments of this application, the charging case 100 may further include a lifting assembly 40, which is 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 against the earphone 200. Figure 1 (As shown); with the cover 20 in the released position, the cover 20 releases the earphone 200.

[0052] 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.

[0053] 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.

[0054] The damping element 30 is a structure in the charging box 100 that restricts the degree of freedom of the extension 23 in the horizontal direction. In some embodiments of this application, the damping element 30 may be disposed in the moving space and cooperate with the inner wall 131 of both the extension 23 and the connector. In this way, the damping element 30 can restrict the degree of freedom of the extension 23 in the horizontal direction. That is, the damping element 30 can block the movement of the extension 23 in the horizontal direction, thereby improving the stability of the cover 20 when it moves relative to the base 10 (e.g., lifting).

[0055] Please see Figure 4 and Figure 5 The damping member 30 provided in this embodiment includes a damping body 31 and an elastic protrusion 33. The damping body 31 includes a first mating surface 311. The elastic protrusion 33 protrudes from the damping body 31 and includes a second mating surface 331. The first mating surface 311 and the second mating surface 331 are located on opposite sides of the damping member 30.

[0056] The damping body 31 is a structure in the damping member 30 that can mate with the extension member 23. In some embodiments of this application, the damping body 31 is connected to the side wall 231 of the extension member, and when the damping body 31 and the extension member 23 are connected, the first mating surface 311 abuts against the side wall 231 of the extension member. The damping body 31 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.

[0057] For example, the damping body 31 is provided with a through connection hole 317, through which a fastener can connect the damping body 31 to the side wall 231 of the extension. It should be noted that in some embodiments, the fastener may be a bolt or screw, etc.

[0058] The elastic protrusion 33 is a structure in the damping member 30 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 331 can cooperate (abut) with the inner wall 131 of the connector. In this way, the provision of the elastic protrusion 33 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.

[0059] It is understandable that the elastic protrusion 33 can undergo elastic deformation and generate elastic restoring force, and the elastic restoring force generated by the elastic protrusion 33 can keep the second mating surface 331 in contact with the inner wall 131 of the connector.

[0060] Specifically, when the extension 23 extends into the connector 13, the inner wall 131 of the connector can exert pressure on the elastic protrusion 33. Under the pressure, the elastic protrusion 33 elastically deforms towards the first mating surface 311 and generates an elastic restoring force. The elastic restoring force can keep the second mating surface 331 in contact with the inner wall 131 of the connector. Therefore, compared to the elastic protrusion 33 not being able to generate elastic deformation, the elastic protrusion 33 in this embodiment can avoid the problem that the second mating surface 331 cannot mate with the inner wall 131 of the connector due to unevenness of the inner wall 131 of the connector, effectively preventing the extension 23 from moving or swaying in the horizontal direction, and improving the stability of the cover 20 relative to the base 10 when moving.

[0061] In some embodiments, the damping element 30 is made of metal.

[0062] Specifically, in some embodiments, the damping body 31 and the elastic protrusion 33 are made of the same material. For example, both the damping body 31 and the elastic protrusion 33 are made of elastic metal, in which case the damping element 30 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 31 and the elastic protrusion 33 are made of different materials. For example, the damping body 31 may be made of a non-elastic metal or an elastic metal; the elastic protrusion 33 may be made of an elastic metal.

[0063] It is understood that in other embodiments, the damping element 30 may also be made of a non-metallic material. For example, the damping element 30 may also be made of at least one of non-metallic elastic materials such as rubber and silicone.

[0064] In some embodiments, the damping body 31 and the elastic protrusion 33 are integrally stamped structures. That is, the damping body 31 and the elastic protrusion 33 can be integrally stamped to form a whole structure. This facilitates the processing and manufacturing of the damping component 30 and improves the production efficiency of the damping component 30. On the other hand, it can improve the connection strength between the damping body 31 and the elastic protrusion 33, reduce the possibility of the elastic protrusion 33 falling off the damping body 31, and extend the service life of the damping component 30.

[0065] In other embodiments, the damping body 31 and the elastic protrusion 33 are separate structures, that is, the damping body 31 and the elastic protrusion 33 are two different structures. The damping body 31 and the elastic protrusion 33 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 bonding or welding.

[0066] In the damping member 30 of this application embodiment, the damping member 30 includes a damping body 31 and an elastic protrusion 33. The first mating surface 311 of the damping body 31 can mate with the extension member 23. The elastic protrusion 33 protrudes from the damping body 31 and the second mating surface 331 of the elastic protrusion 33 can mate with the inner wall 131 of the connector. Thus, the provision of the elastic protrusion 33 can restrict the degree of freedom of the extension member 23 in the horizontal direction, prevent the extension member 23 from moving or shaking in the horizontal direction, thereby improving the stability of the cover 20 when moving relative to the base 10 and improving the operating feel.

[0067] In addition, the damping component 30 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, which would cause excessive noise and thus improve the user experience.

[0068] The damping element 30 will be further explained below with reference to the accompanying drawings.

[0069] Please see Figure 4 and Figure 5 If the elastic protrusion 33 includes only one; or if the elastic protrusion 33 includes at least two, and the at least two elastic protrusions 33 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 the elastic protrusion 33 includes three, and the three elastic protrusions 33 are collinearly arranged along the height direction Z of the charging case 100, the extension 23 is prone to deflection in the connector 13 about the height direction Z of the charging case 100 during the movement of the cover 20 relative to the base 10.

[0070] In some embodiments of this application, the elastic protrusions 33 include at least three, and the centers of the at least three elastic protrusions 33 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, uncurved line that can simultaneously pass through all the elements. The fact that the centers of the at least three elastic protrusions 33 are not collinear means that the centers of the at least three elastic protrusions 33 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.

[0071] For example, in some embodiments, when the elastic protrusions 33 include three and the centers of the three elastic protrusions 33 are not collinear, the line connecting the centers of the three elastic protrusions 33 can form a triangle. Thus, compared to the three elastic protrusions 33 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.

[0072] In some embodiments, the resilient protrusions 33 include at least three, which are evenly distributed around the center of the sidewall 231 of the extension. 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.

[0073] Please see Figure 5 In some embodiments, the elastic protrusion 33 includes a first sub-part 333 and a second sub-part 335 that are bent together. The first sub-part 333 extends from the damping body 31 in a direction away from the first mating surface 311, and the second sub-part 335 extends from the end of the first sub-part 333 away from the damping body 31 toward the first mating surface 311. The connection 337 of the first sub-part 333 and the second sub-part 335 is configured to participate in forming the second mating surface 331.

[0074] Specifically, please combine Figure 4In some embodiments, the free end 339 of the elastic protrusion 33 is spaced apart from the first mating surface 311, that is, the end of the second sub-part 335 away from the first sub-part 333 is spaced apart from the first mating surface 311. This ensures that the elastic protrusion 33 can undergo elastic deformation when subjected to force. The connection 337 between the first sub-part 333 and the second sub-part 335 is the bend between the first sub-part 333 and the second sub-part 335. When the extension 23 extends into the connector 13, the connection 337 between the first sub-part 333 and the second sub-part 335 can abut against the inner wall 131 of the connector. That is, the contact surface between the elastic protrusion 33 and the inner wall 131 of the connector can be an arc surface. This reduces the friction between the elastic protrusion 33 and the connector 13, preventing excessive friction between the elastic protrusion 33 and the connector 13 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.

[0075] It should be noted that in some embodiments, when there are multiple elastic protrusions 33, the connection points 337 of the multiple elastic protrusions 33 (the connection points 337 of the first sub-part 333 and the second sub-part 335) can jointly form the second mating surface 331.

[0076] In some embodiments, the damping body 31 is provided with a clearance space 315, at least a portion of the elastic protrusion 33 is disposed in the clearance space 315, and the free end 339 of the elastic protrusion 33 is spaced apart from the bottom wall of the clearance space 315.

[0077] Specifically, in some embodiments, the damping body 31 further includes a third mating surface 313 opposite to the first mating surface 311, and the clearance space 315 can be recessed from the third mating surface 313 toward the first mating surface 311. The clearance space 315 provides deformation space for the elastic protrusion 33, preventing it from directly contacting the third mating surface 313 when deformed under force; it also reduces the space occupied by the damping body 31 and the elastic protrusion 33, facilitating miniaturization of the damping component 30; and it further reduces the weight of the damping component 30, contributing to its lightweight design.

[0078] In some embodiments, the clearance space 315 may be a through groove, that is, the clearance space 315 penetrates through the first mating surface 311 and the third mating surface 313. In this case, the bottom wall of the clearance space 315 coincides with the first mating surface 311. In other embodiments, the clearance space 315 may be a blind groove, that is, the clearance space 315 is recessed from the third mating surface 313 toward the first mating surface 311 and does not penetrate the first mating surface 311.

[0079] In some embodiments, the damping body 31 has a flat plate structure. This facilitates the fabrication of the elastic protrusions 33, ensuring that when there are multiple elastic protrusions 33, the connection points 337 of the multiple elastic protrusions 33 can be in the same plane, thereby improving the product yield of the damping component 30.

[0080] Please see Figure 3 and Figure 4 In some embodiments, a clearance groove may be provided on the side wall 231 of the extension member, the clearance groove being recessed from the side wall 231 of the extension member toward the center of the extension member 23, and at least a portion of the damping member 30 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 30, 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 30, thereby improving the assembly efficiency of the charging box 100.

[0081] In some embodiments, the damping element 30 includes two damping elements 30, 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.

[0082] 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 30 are respectively disposed on the first side 2311 and the third side 2315 of the extension; or, the two damping members 30 are respectively disposed on the second side 2313 and the fourth side 2317 of the extension.

[0083] In some embodiments, a first guide 41 is provided on the side wall 231 of the extension member, and a second guide 43 is provided on the inner wall 131 of the connector member. The first guide 41 and the second guide 43 cooperate to guide the extension member 23 to rise and fall relative to the connector member 13.

[0084] Specifically, in some embodiments, the lifting assembly 40 may include a first guide 41 and a second guide 43. The first guide 41 is disposed on the side wall 231 of the extension member, and the second guide 43 is disposed on the inner wall 131 of the connector member. Thus, the first guide 41 and the second guide 43 cooperate to guide the lifting and lowering of the extension member 23 relative to the connector member 13. In addition, the cooperation of the first guide 41 and the second guide 43 can also limit the horizontal movement of the cover 20 relative to the base 10, thereby preventing the cover 20 from loosening or shaking during movement relative to the base 10, and thus improving the stability of the opening and closing of the charging case 100.

[0085] More specifically, 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. In this application, the embodiments are described only with the example of the first guide member 41 being a groove and the second guide member 43 being a protrusion.

[0086] The first guide member 41 is recessed from the side wall 231 of the extension member toward the center of the extension member 23; the second guide member 43 is protruding from the inner wall 131 of the connector toward the center of the connector 13. When the extension member 23 is inserted into the connector 13, the second guide member 43 can be inserted into the first guide member 41 to guide the extension member 23 to rise and fall relative to the connector 13.

[0087] In some embodiments, two damping elements 30 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. The second side 1313 of the inner wall of the connector is opposite to the second side 2313 of the extension, and the fourth side 1317 of the inner wall of the connector is opposite to the fourth side 2317 of the extension. This prevents interference between the first guide element 41 and the damping element 30, 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 30, thus improving the stability of the cover 20 relative to the base 10.

[0088] 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; 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.

[0089] 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.

[0090] In other embodiments, two damping elements 30 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. The first side 1311 of the inner wall of the connector is opposite to the first side 2311 of the extension, and the third side 1315 of the inner wall of the connector is opposite to the third side 2315 of the extension. The first guide element 41 and the damping element 30 are spaced apart. This prevents interference between the first guide element 41 and the damping element 30, 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 30, thereby improving the stability of the cover 20 relative to the base 10.
