Description

Button structure, charging case and earphone system Technical Field

[0001] This application relates to the field of electronic device technology, and more specifically, to a button structure, 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 store them in the charging case. The charging case includes a base and a lid, which are usually connected magnetically. However, the magnetic force is easily affected by external factors. For instance, if the magnetic force decreases due to external influences, the lid may accidentally open under slight external force or vibration, affecting the stability of the earphones; conversely, if the magnetic force increases due to external influences, the lid may be difficult to open, affecting the placement and removal of the earphones. In summary, the magnetic connection between the base and lid can easily affect the stability of the charging case.

[0003] Summary of the Invention

[0004] To address at least one of the aforementioned technical problems, this application provides a button structure, a charging case, and an earphone system.

[0005] The button structure provided in this application is used in a charging case, which includes a base and a cover that are movably connected. The button structure includes a locking component, a mating component, and a resetting component. The locking component reciprocates between a locked position and a first unlocked position along a first direction, and is used to connect one of the base and the cover. The mating component reciprocates between a locked position and a second unlocked position along a second direction, and is used to connect the other of the base and the cover. One end of the resetting component is connected to the mating component, and the other end is connected to the base or the cover. The resetting component is used to hold the mating component in the locked position; wherein the first direction and the second direction intersect, and when the locking component and the mating component are in the locked position, the locking component and the mating component are engaged.

[0006] In some embodiments, the cover 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 engaging member and the mating member are in the locked position. When the cover is in the released position, the engaging member is in the first unlocked position and the mating member is in the second unlocked position. The first direction is the lifting direction of the cover.

[0007] In some embodiments, the button structure further includes an elastic element connected between the base and the cover and extending along the first direction, and a reset element connected between the mating member and the base and extending along the second direction. When the cover is in the pressed position, the elastic element has a first length and the reset element is in a first state; when the cover is in the released position, the elastic element has a second length and the reset element is in a second state, the second length being greater than the first length.

[0008] In some embodiments, during the process of the cover switching from the pressed position to the released position, the reset member sequentially switches between the first state, the second state, and the first state. During the process of the cover switching from the released position to the pressed position, the reset member sequentially switches between the first state, the second state, and the first state, and the length of the reset member in the first state is different from the length of the reset member in the second state.

[0009] In some embodiments, when the cover is in the pressed position and the mating member is subjected to a first force, the mating member can move forward along the second direction, the reset member switches from the first state to the second state, and the elastic member extends and pushes the cover to move along the upward direction of the cover; when the first force disappears, the reset member switches from the second state to the first state, the mating member moves in the opposite direction along the second direction, and is located below the engaging member.

[0011] In some embodiments, the first force acting on the mating member is pressure, the length of the reset member in the first state is greater than the length of the reset member in the second state, the positive direction of the second direction is the direction towards the inside of the base, and the negative direction of the second direction is the direction towards the outside of the base.

[0012] In some embodiments, the first force acting on the mating member is a tensile force, the length of the reset member in the first state is less than the length of the reset member in the second state, the positive direction of the second direction is the direction towards the outside of the base, and the negative direction of the second direction is the direction towards the inside of the base.

[0013] In some embodiments, the mating member includes a mating body and a hook portion, and the engaging member includes an engaging body and an engaging portion, wherein the hook portion engages with the engaging portion to engage the mating member with the engaging member.

[0014] In some embodiments, the engaging portion has a first inclined surface and the hook portion has a second inclined surface, and during the process of the cover switching from the release position to the pressing position, the first inclined surface and the second inclined surface abut against each other.

[0015] In some embodiments, the engaging portion has a first plane and the hook portion has a second plane, and when the cover is in the pressed position, the first plane and the second plane abut against each other.

[0016] In some embodiments, the base is provided with a blocking member and a supporting member. One end of the resetting member is connected to the blocking member, and the other end is connected to the mating member. The mating member is supported on the supporting member and can move along the second direction on the supporting member.

[0017] In some embodiments, the mating member includes a contact surface opposite to the support member, and the contact area between the support member and the contact surface is smaller than the area of ​​the contact surface.

[0018] In some embodiments, the button structure further includes a pressing member connected to the mating member and movable along a second direction with the mating member, the pressing member being exposed from the side wall of the base.

[0019] In some embodiments, the base has a through hole that penetrates the side wall and / or bottom wall of the base, at least a portion of the mating member is located inside the base, and the pressing member passes through the through hole and is connected to the mating member.

[0020] In some embodiments, the base is provided with a through hole that penetrates the side wall and / or bottom wall of the base; the base is also provided with a blocking member, the opposite ends of which are connected to the inner side of the side wall of the base and divide the base into a first cavity and a second cavity, the mating member and the resetting member are both housed in the first cavity, and the through hole communicates with the first cavity.

[0021] In some embodiments, the base includes a limiting member, and the pressing member includes an extension wall, the limiting member partially enclosing the extension wall to at least limit the extension wall from warping toward the cover.

[0039] Referring to Figure 1, the headphone system 3000 provided in this embodiment includes headphones 2000 and a charging case 1000. The charging case 1000 is used to charge the headphones 2000. Since the headphone system 3000 in this embodiment includes the charging case 1000, it is understood that the headphone system 3000 includes at least the same beneficial effects as the charging case 1000. Therefore, for the beneficial effects of the headphone system 3000, please refer to the beneficial effects of the charging case 1000 described below.

[0040] In some embodiments of this application, the earphone 2000 can be worn on the 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 and smart helmets), head-mounted displays and virtual reality devices.

[0041] Specifically, in some embodiments, the headphone 2000 includes air-conduction headphones and bone-conduction headphones. Air-conduction headphones, also known as air-conduction headphones, are headphones that transmit sound through air vibrations. Bone-conduction headphones, also known as bone-conduction headphones, are headphones that convert sound into different mechanical vibrations and transmit sound waves through the skull, bony labyrinth, inner ear fluid, cochlea, auditory center, etc.

[0042] 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.

[0043] Furthermore, in some embodiments, the earphone 2000 includes a transducer assembly 2100 (including a first transducer assembly 2101 and a second transducer assembly 2103), which is a structure in the earphone 2000 used to enable the user to hear sound. In one example, when the earphone 2000 is a bone conduction earphone 2000, the transducer assembly 2100 is configured to be located on the front side of the ear when the earphone 2000 is worn, in which case the transducer assembly 2100 does not block the external auditory canal. In another example, when the earphone 2000 is an air conduction earphone 2000, the transducer assembly 2100 is configured to at least partially extend into at least one part of the concha, cymba conchae, and triangular fossa when the earphone 2000 is worn. It should be noted that the embodiments described below only use a bone conduction earphone 2000 as an example.

[0044] Furthermore, in some embodiments, the earphone 2000 includes a battery compartment 2200, a control compartment 2300, a first ear hook assembly 2400, a second ear hook assembly 2500, and a back hook assembly 2600 disposed between the first ear hook assembly 2400 and the second ear hook assembly 2500. The first ear hook assembly 2400 and the second ear hook assembly 2500 are respectively hooked onto the left and right ears. The battery compartment 2200 may be disposed between the first ear hook assembly 2400 and the back hook assembly 2600, and the control compartment 2300 may be disposed between the second ear hook assembly 2500 and the back hook assembly 2600. The first transducer assembly 2101 and the second transducer assembly 2103 are both used to convert electrical signals into mechanical vibrations so that the user can hear sound. When the earphone 2000 is in the wearing state, both the first transducer assembly 2101 and the second transducer assembly 2103 are located on the front side of the ear.

[0045] Please refer to Figures 1 and 4. In some embodiments, the charging case 1000 includes a rechargeable battery 400 and a charging circuit 500. When the earphone 2000 is placed in the charging case 1000, the charging circuit 500 can deliver electrical energy from the rechargeable battery 400 to the earphone 2000 to charge the earphone 2000.

[0046] Furthermore, referring to Figures 2 and 3, in some embodiments, the charging case 1000 is provided with a first electrical connector 250, and the earphone 2000 is provided with a second electrical connector 2700. When the earphone 2000 is placed in the charging case 1000, the first electrical connector 250 and the second electrical connector 2700 are electrically connected.

[0047] Specifically, in some embodiments, when the first electrical connector 250 and the second electrical connector 2700 are electrically connected, the charging case 1000 and the earphone 2000 can perform functions such as power transmission and data transmission. For example, when the first electrical connector 250 and the second electrical connector 2700 are electrically connected, the charging circuit 500 can transmit the electrical energy of the rechargeable battery 400 to the battery compartment 2200 of the earphone 2000 through the first electrical connector 250 and the second electrical connector 2700, thereby charging the earphone 2000. It should be noted that in some embodiments, the first electrical connector 250 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 2700 can be a device that can be electrically connected to the first electrical connector 250.

[0048] Furthermore, in some embodiments, the first electrical connector 250 includes multiple components, and the second electrical connector 2700 includes multiple components. When the earphone 2000 is placed in the charging case 1000, the multiple first electrical connectors 250 and the multiple second electrical connectors 2700 are electrically connected in a one-to-one correspondence.

[0049] Specifically, in some embodiments, a portion of the plurality of first electrical connectors 250 is used for power transmission, and another portion is used for signal transmission; correspondingly, a portion of the plurality of second electrical connectors 2700 is used for power transmission, and another portion is used for signal transmission. The plurality of first electrical connectors 250 are arranged side-by-side on the charging case 1000. This arrangement, compared to a non-side-by-side arrangement, reduces the space occupied by the first electrical connectors 250, making the structure more compact and facilitating the miniaturization of the charging case 1000. Furthermore, it facilitates the alignment of the first electrical connectors 250 and the second electrical connectors 2700, improving the convenience of electrical connection.

[0050] Please refer to Figures 1, 3 and 4. The charging box 1000 provided in this embodiment includes a base 200, a cover 300 and a button structure 100. The cover 300 is movably connected to the base 200.

[0051] The base 200 is a structure in the charging case 1000 used to support the earphones 2000. In some embodiments of this application, both the rechargeable battery 400 and the charging circuit 500 are disposed in the base 200. This makes the base 200 relatively heavy, reducing the possibility of the charging case 1000 tipping over when the earphones 2000 are stored in it. The base 200 is made of materials including, but not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, the base 200 is made of plastic, which makes the charging case 1000 lighter and easier for users to carry.

[0052] The cover 300 is a structure in the charging case 1000 that can cooperate with the base 200 to confine the earphones 2000. In some embodiments of this application, the projection of the cover 300 in the direction perpendicular to the height of the charging case 1000 coincides with the projection of the base 200 in the same direction; or, the projection of the cover 300 in the direction perpendicular to the height of the charging case 1000 is located within the projection of the base 200 in the same direction. The material of the cover 300 includes, but is not limited to, plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, the cover 300 is made of plastic, which makes the charging case 1000 lighter and easier for users to carry. It is understood that the material of the cover 300 and the material of the base 200 may be the same or different.

[0053] A movable connection refers to a connection method between two or more components that allows relative movement between the connected components. In some embodiments of this application, the cover 300 and the base 200 are movably connected, meaning that the cover 300 and the base 200 can rotate, slide, or rise and fall relative to each other. Thus, when the cover 300 moves relative to the base 200, the cover 300 can switch between a pressed position and a released position. Specifically, when the cover 300 is in the pressed position, it can press the earphone 2000, at which time the earphone 2000 can be stored in the charging case 1000; when the cover 300 is in the released position, it can release the earphone 2000, at which time the earphone 2000 can be removed from the charging case 1000.

[0054] Since the charging box 1000 in this embodiment includes a button structure 100, it is understood that the charging box 1000 has at least the same beneficial effects as the button structure 100. Therefore, for the beneficial effects of the charging box 1000, please refer to the beneficial effects of the button structure 100 described below.

[0055] Please refer to Figures 1 and 4. The button structure 100 provided in this embodiment is used in a charging case 1000. The button structure 100 includes a locking member 10, a mating member 20, and a resetting member 30. The locking member 10 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 200 and the cover 300. The mating member 20 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 200 and the cover 300. One end of the resetting member 30 is connected to the mating member 20, and the other end of the resetting member 30 is connected to the base 200 or the cover 300, and the resetting member 30 is used to hold the mating member 20 in the locked position. Wherein, the first direction (Z1 / Z2) and the second direction (X1 / X2) intersect, and when the engaging part 10 and the mating part 20 are in the locked position, the engaging part 10 and the mating part 20 engage.

[0056] In some embodiments, the engaging member 10 is connected to the cover 300, the mating member 20 is connected to the base 200, and the resetting member 30 is connected between the mating member 20 and the base 200. In other embodiments, the engaging member 10 is connected to the base 200, the mating member 20 is connected to the cover 300, and the resetting member 30 is connected between the mating member 20 and the cover 300. This application only describes an example where the engaging member 10 is connected to the cover 300, the mating member 20 is connected to the base 200, and the resetting member 30 is connected between the mating member 20 and the base 200.

[0057] Specifically, in some embodiments, when the engaging member 10 and the mating member 20 are in the locked position, the engaging member 10 and the mating member 20 are engaged (click-fitted), in which case the cover 300 can press the earphone 2000; when the engaging member 10 is in the first unlocked position and the mating member 20 is in the second unlocked position, the engaging member 10 and the mating member 20 are disengaged (unlocked), in which case the cover 300 can release the earphone 2000.

[0058] It is understood that in some embodiments, the reciprocating movement of the mating member 20 along the second direction (X1 / X2) between the locked position and the second unlocked position requires manual intervention. That is, the mating member 20 is manually switched between the locked position and the second unlocked position along the second direction (X1 / X2); or, the mating member 20 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 20, the mating member 20 can move relative to the base 200 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 20, the mating member 20 can move along the second direction (X1 / X2) from the second unlocked position to the locked position under the action of the reset member 30. When the mating part 20 moves along the second direction (X1 / X2), the base 200 will not move along the second direction (X1 / X2) with the mating part 20. In other words, the mating part 20 can move relative to the base 200 along the second direction (X1 / X2).

[0059] The reciprocating movement of the engaging component 10 along the first direction (Z1 / Z2) between the locked position and the first unlocked position requires manual intervention. Specifically, the engaging component 10 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 10 between the locked and unlocked positions along the first direction (Z1 / Z2). For example, when the user applies force to the engaging component 10, the engaging component 10 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 10 and the mating part 20 is in the second unlocked position, the engaging component 10 can move from the locked position to the first unlocked position along the first direction (Z1 / Z2). When the engaging component 10 moves along the first direction (Z1 / Z2), the cover 300 moves along the first direction (Z1 / Z2) along with the engaging component 10.

[0060] 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 of the charging case 1000. In other examples, as long as the first direction (Z1 / Z2) and the second direction (X1 / X2) intersect, the angle between them can be any angle between (0° and 180°), such as 15°, 30°, 45°, 60°, 75°, 100°, 115°, 120°, or 135°, etc. This application embodiment only uses the example of the first direction (Z1 / Z2) and the second direction (X1 / X2) being perpendicular as an example for illustration.

[0061] In the button structure 100 of this application embodiment, the engaging member 10 reciprocates between a locked position and a first unlocked position along a first direction (Z1 / Z2), and the engaging member 10 connects to one of the base 200 and the cover 300. The mating member 20 reciprocates between a locked position and a second unlocked position along a second direction (X1 / X2), and the mating member 20 connects to the other of the base 200 and the cover 300. When the engaging member 10 and the mating member 20 are in the locked position, the engaging member 10 and the mating member 20 engage and cooperate. Therefore, compared with the charging box in the related art, the button structure 100 can prevent the relative movement between the cover 300 and the base 200 from being unstable due to changes in magnetic attraction, thereby improving the stability of the charging box 1000.

[0062] The button structure 100 will be further explained below with reference to the attached diagram.

[0063] Please refer to Figures 3 and 4. In some embodiments, the cover 300 can be raised and lowered relative to the base 200 to switch between a pressed position and a released position. When the cover 300 is in the pressed position, the engaging member 10 and the mating member 20 are in the locked position. When the cover 300 is in the released position, the engaging member 10 is in the first unlocked position and the mating member 20 is in the second unlocked position. The first direction (Z1 / Z2) is the direction of raising and lowering the cover 300.

[0064] Specifically, in some embodiments, the pressing position may be: the limit position to which the cover 300 can move downward relative to the base 200 along the lifting direction of the cover 300 (the same as the height direction of the charging box 1000); the releasing position may be: the limit position to which the cover 300 can move upward relative to the base 200 along the lifting direction of the cover 300 (the same as the height direction of the charging box 1000);

[0065] More specifically, referring to Figure 1, in some embodiments, when the cover 300 is in the pressed position, the cover 300 can press the earphone 2000, thereby limiting the earphone 2000 and preventing it from moving or shaking within the charging case 1000, thus improving the stability of the earphone 2000 stored in the charging case 1000. Simultaneously, the pressed position of the cover 300 also prevents the earphone 2000 from moving or shaking within the charging case 1000, which could lead to poor contact between the charging terminal of the earphone 2000 (i.e., the second electrical connector 2700) and the charging terminal of the charging case 1000 (i.e., the first electrical connector 250), thereby improving the stability of the charging of the earphone 2000 by the charging case 1000 and ensuring the normal operation of the charging function and / or signal transmission function. When the cover 300 is in the released position, the earphone 2000 can be placed into the charging case 1000; or, the earphone 2000 can be removed from the charging case 1000.

[0066] Furthermore, in some embodiments, the cover 300 and the base 200 together form an earphone compartment 201 for accommodating earphones 2000.

[0067] Specifically, in some embodiments, when the engaging member 10 moves from the locked position to the first unlocked position and the mating member 20 moves from the locked position to the second unlocked position, the cover 300 switches from the pressing position to the releasing position, and the size of the earphone compartment 201 in the height direction of the charging case 1000 increases. In this case, the earphone 2000 can be placed into the earphone compartment 201; or, the earphone 2000 can be removed from the earphone compartment 201. When the engaging member 10 moves from the first unlocked position to the locked position and the mating member 20 moves from the second unlocked position to the locked position, the cover 300 switches from the releasing position to the pressing position, and the size of the earphone compartment 201 in the height direction of the charging case 1000 decreases. In this case, the cover 300 can press the charging compartment of the earphone 2000 into the earphone compartment 201, and the charging case 1000 can charge the earphone 2000.

[0068] In some embodiments, the earphone compartment 201 includes a first side 2011, a second side 2013, a third side 2015, and a fourth side 2017 connected in sequence. At least one of the first side 2011, the second side 2013, the third side 2015, and the fourth side 2017 of the earphone compartment is open to allow the earphone 2000 to be inserted into the earphone compartment 201.

[0069] Specifically, in some embodiments, on a plane perpendicular to the height direction of the charging case 1000 (i.e., the first direction (Z1 / Z2)), the earphone compartment 201 includes a first side 2011, a second side 2013, a third side 2015, and a fourth side 2017 connected sequentially. At least one of the first side 2011, the second side 2013, the third side 2015, and the fourth side 2017 of the earphone compartment is open. Thus, when the cover 300 is raised relative to the base 200, the earphones 2000 can be placed into the earphone compartment 201 through the open side (including at least one of the first side 2011, the second side 2013, the third side 2015, and the fourth side 2017), thereby enabling the charging case 1000 to charge and store the earphones 2000.

[0070] In some embodiments of this application, the first side 2011 of the earphone compartment is closed, while the second side 2013, the third side 2015, and the fourth side 2017 of the earphone compartment are open. In this case, when the cover 300 rises relative to the base 200, the earphone 2000 can be inserted into the earphone compartment 201 through the second side 2013 along the direction from the second side 2013 to the fourth side 2017 of the earphone compartment; or, the earphone 2000 can be inserted into the earphone compartment 201 through the third side 2015 along the direction from the third side 2015 to the first side 2011 of the earphone compartment.

[0071] Furthermore, referring to Figures 3 to 5, in some embodiments, the cover 300 includes a main body 310 and an extension 330. The extension 330 extends from the main body 310 toward the base 200. The base 200 includes a seat 210 and a connector 230. The connector 230 extends from the seat 210 toward the cover 300. The extension 330 partially extends into the connector 230 and is able to move up and down relative to the connector 230 to switch the cover 300 between a pressed position and a released position.

[0072] Specifically, in some embodiments, a portion of the extension 330 can extend into the connector 230 and can move up and down relative to the connector 230. Thus, the connector 230 can guide and limit the movement of the extension 330, preventing it from jamming during lifting and lowering, thereby improving the stability of the cover 300 relative to the base 200. It is understood that the projection of the extension 330 onto the base 210 is located within the connector 230, ensuring that a portion of the extension 330 can extend into the connector 230, thereby enabling the extension 330 to move up and down relative to the connector 230.

[0073] More specifically, in some embodiments, the base 210 includes a base body 211 and a top cover 213 connected together, and the rechargeable battery 400 and the charging circuit 500 are both disposed inside the base 210. The base body 211 and the top cover 213 are detachably connected, which facilitates the installation of the rechargeable battery 400 and the charging circuit 500.

[0074] In some embodiments, the button structure 100 further includes an elastic element 40 connected between the base 200 and the cover 300 and extending along a first direction (Z1 / Z2). A reset element 30 is connected between the mating element 20 and the base 200 and extends along a second direction (X1 / X2). When the cover 300 is in the pressed position, the elastic element 40 has a first length, and the reset element 30 is in a first state; when the cover 300 is in the released position, the elastic element 40 has a second length, and the reset element 30 is in a second state, the second length being greater than the first length.

[0075] Specifically, in some embodiments, when the cover 300 switches from the pressed position to the released position, the size of the earphone compartment 201 in the height direction of the charging case 1000 increases, and the second length of the elastic member 40 when the cover 300 is in the released position is greater than the first length of the elastic member 40 when the cover 300 is in the pressed position. Therefore, when the cover 300 is in the pressed position, the elastic member 40 is in a compressed state; when the cover 300 is in the released position, the elastic member 40 is in a normal state (not stretched or compressed) or a compressed state (at which time the compression amount of the elastic member 40 is less than the compression amount of the elastic member 40 when the cover 300 is in the pressed position). Thus, during the process of the cover 300 switching from the pressed position to the released position, the elastic member 40 can provide elastic force to the cover 300, thereby ensuring that the cover 300 can rise smoothly relative to the base 200.

[0076] In some embodiments, during the process of switching the cover 300 from the pressed position to the released position, the reset member 30 sequentially switches between a first state, a second state, and a third state. During the process of switching the cover 300 from the released position to the pressed position, the reset member 30 sequentially switches between a first state, a second state, and a third state. The length of the reset member 30 in the first state is different from the length of the reset member 30 in the second state.

[0077] Specifically, in some embodiments, when the reset member 30 is in the first state, both the locking member 10 and the mating member 20 are in the locked position; when the reset member 30 is in the second state, the locking member 10 is in the first unlocked position and the mating member 20 is in the second unlocked position.

[0078] Specifically, when the cover 300 switches from the pressed position to the released position, the reset member 30 sequentially switches between a first state, a second state, and a first state again; that is, the mating member 20 sequentially switches between a locked position, a second unlocked position, and a locked position. When the mating member 20 moves from the locked position to the second unlocked position, the mating member 20 and the engaging member 10 are released from their engaging position, and the engaging member 10 moves from the locked position to the first unlocked position. It is understood that the length of the reset member 30 in the first state is different from the length of the reset member 30 in the second state. Thus, the reset member 30 can generate a reset force on the mating member 20, which is used to keep the mating member 20 in the locked position.

[0079] Furthermore, in some embodiments, when the cover 300 is in the pressed position and the mating member 20 is subjected to a first force, the mating member 20 can move in the positive direction X1 along the second direction (X1 / X2), the reset member 30 switches from the first state to the second state, and the elastic member 40 extends and pushes the cover 300 to move in the upward direction of the cover 300; when the first force disappears, the reset member 30 switches from the second state to the first state, the mating member 20 moves in the opposite direction X2 along the second direction (X1 / X2), and is located below the engaging member 10.

[0080] Specifically, in some embodiments, when the mating member 20 is subjected to a first force and moves in the positive direction X1 of the second direction (X1 / X2), the reset member 30 generates a reset force, and the mating member 20 moves from the locked position to the second unlocked position to release the engagement between the mating member 20 and the engaging member 10. The elastic force of the elastic member 40 can push the cover 300 to move in the upward direction of the cover 300. When the first force disappears, the reset force of the reset member 30 can cause the mating member 20 to move in the opposite direction X2 of the second direction (X1 / X2), that is, the reset force can cause the mating member 20 to move from the second unlocked position to the locked position. In this case, the mating member 20 is located below the engaging member 10. Thus, when the mating member 20 is subjected to the first force, the cover 300 can switch from the pressed position to the released position.

[0081] In some embodiments, when the cover 300 is in the released position and the cover 300 is subjected to a second force, the elastic member 40 is compressed, the cover 300 moves in the downward direction of the cover 300, the engaging member 10 pushes the mating member 20 to move in the positive direction X1 of the second direction (X1 / X2), and the reset member 30 switches from the first state to the second state; when the engaging member 10 is in the locked position, the mating member 20 moves in the opposite direction X2 of the second direction (X1 / X2), and the reset member 30 switches from the second state to the first state.

[0082] Specifically, in some embodiments, when the cover 300 is subjected to a second force and moves along the downward direction of the cover 300 (the direction from the cover 300 to the base 200), the engaging member 10 exerts a pushing force on the mating member 20 to push the mating member 20 to move along the positive direction X1 of the second direction (X1 / X2). At this time, the resetting member 30 generates a resetting force, and the mating member 20 moves from the locked position to the second unlocked position. When the engaging member 10 moves to the locked position along the downward direction of the cover 300, the engaging member 10 does not exert a pushing force on the mating member 20, and the resetting force of the resetting member 30 can cause the mating member 20 to move in the opposite direction X2 of the second direction (X1 / X2). That is, the resetting force can cause the mating member 20 to move from the second unlocked position to the locked position. In this case, the engaging member 10 and the mating member 20 are engaged. Thus, when the cover 300 is subjected to the second force, the cover 300 can switch from the released position to the pressed position.

[0083] Please refer to Figures 3 to 5. In some embodiments, the first force on the mating member 20 is pressure. The length of the reset member 30 in the first state is greater than the length of the reset member 30 in the second state. The positive direction X1 of the second direction (X1 / X2) is the direction towards the inside of the base 200, and the negative direction X2 of the second direction (X1 / X2) is the direction towards the outside of the base 200.

[0084] Specifically, referring to Figures 4 and 5, in some embodiments, when the engaging member 10 and the mating member 20 are engaged, the reset member 30 is located on the side of the mating member 20 opposite to the engaging member 10. In this case, the reset member 30 can be a compression spring. When the reset member 30 is in the first state, the mating member 20 is in the locked position, and the reset member 30 is in the normal state (not stretched or compressed) or in the first compressed state. When the reset member 30 is in the second state, the mating member 20 is in the second unlocked position, and the reset member 30 is in the second compressed state. The length of the reset member 30 in the first compressed state is greater than the length of the reset member 30 in the second compressed state.

[0085] Please refer to Figures 3 and 7. In some embodiments, the first force on the mating member 20 is a tensile force, the length of the reset member 30 in the first state is less than the length of the reset member 30 in the second state, the positive direction X1 of the second direction (X1 / X2) is the direction towards the outside of the base 200, and the negative direction X2 of the second direction (X1 / X2) is the direction towards the inside of the base 200.

[0086] Specifically, referring to Figure 7, in some embodiments, when the engaging member 10 and the mating member 20 are engaged, the resetting member 30 is located on the side of the mating member 20 opposite to the engaging member 10. In this case, the resetting member 30 can be a tension spring. When the resetting member 30 is in the first state, the mating member 20 is in the locked position, and the resetting member 30 is in a normal state (not stretched or compressed) or in a first stretched state. When the resetting member 30 is in the second state, the mating member 20 is in the second unlocked position, and the resetting member 30 is in a second stretched state. The length of the resetting member 30 in the first stretched state is less than the length of the resetting member 30 in the second stretched state.

[0087] Please refer to Figures 3 to 5, and in conjunction with Figure 6 or 7. In some embodiments, the mating member 20 includes a mating body 21 and a hook portion 23, and the engaging member 10 includes an engaging body 11 and an engaging portion 13. The hook portion 23 engages with the engaging portion 13 so that the mating member 20 and the engaging member 10 are engaged.

[0088] Specifically, in some embodiments, when both the engaging member 10 and the mating member 20 are in the locked position, the hook portion 23 engages with the engaging member 13; when the engaging member 10 is in the first unlocked position and the mating member 20 is in the second unlocked position, the hook portion 23 disengages from the engaging member 13.

[0089] In some embodiments, the mating body 21 and the hook portion 23 are an integral structure, that is, the mating body 21 and the hook portion 23 can be integrally formed into a whole, which can improve the stability of the connection between the mating body 21 and the hook portion 23 and prevent the hook portion 23 from falling off the mating body 21 when it is engaged with the engaging portion 13, thereby ensuring the stability and reliability of the button structure 100 in operation.

[0090] In other embodiments, the mating body 21 and the hook portion 23 are separate structures, meaning they are two distinct structures. In one example, the mating body 21 and the hook portion 23 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 21 and the hook portion 23 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 11 and the engaging portion 13 is essentially the same as that between the mating body 21 and the hook portion 23, and will not be elaborated upon here.

[0091] Furthermore, in some embodiments, the engaging portion 13 is provided with a first inclined surface 131, and the hook portion 23 is provided with a second inclined surface 231. During the process of the cover 300 switching from the release position to the pressing position, the first inclined surface 131 and the second inclined surface 231 abut against each other.

[0092] If the engaging portion 13 does not have a first inclined surface 131 and the hook portion 23 does not have a second inclined surface 231, then when the engaging portion 13 moves along the descending direction of the cover 300 to abut against the hook portion 23, the engaging portion 13 can only exert a pushing force on the hook portion 23 in the first direction (Z1 / Z2) (i.e., the lifting direction of the charging box 1000), and this pushing force cannot push the hook portion 23 to move in the second direction (X1 / X2). Therefore, the provision of the first inclined surface 131 and the second inclined surface 231 allows the engaging portion 13 to exert a pushing force on the hook portion 23 when the first inclined surface 131 and the second inclined surface 231 abut against each other, and the component of this pushing force in the second direction (X1 / X2) can push the hook portion 23 to move in the second direction (X1 / X2).

[0093] Specifically, in some embodiments, the angle between the first inclined plane 131 and the positive direction X1 of the second direction (X1 / X2) is a first acute angle, and the angle between the second inclined plane 231 and the positive direction X1 of the second direction (X1 / X2) is also a second acute angle. It should be noted that in some embodiments, the first acute angle and the second acute angle may be the same or different.

[0094] In some embodiments, the engaging portion 13 has a first plane 133, and the hook portion 23 has a second plane 233. When the cover 300 is in the pressed position, the first plane 133 and the second plane 233 abut against each other. Both the first plane 133 and the second plane 233 can be perpendicular to the first direction (Z1 / Z2). Therefore, the abutment of the first plane 133 and the second plane 233 enables a snap-fit ​​engagement between the engaging portion 13 and the mating portion, thereby restricting the lifting and lowering of the cover 300 relative to the base 200.

[0095] Referring to Figures 4 and 5, in some embodiments, a first guide member 600 is provided on the base 200 or the cover 300. The first guide member 600 extends along a first direction (Z1 / Z2) and cooperates with the elastic member 40 to guide the extension and retraction of the elastic member 40. The first guide member 600 can restrict and guide the deformation of the elastic member 40, reducing or even preventing deformation of the elastic member 40 in directions other than the first direction (Z1 / Z2), ensuring that the elastic member 40 can provide effective elastic force to the cover 300, so that the cover 300 can switch from a pressed position to a released position. It should be noted that the number of first guide members 600 and elastic members 40 is in a one-to-one correspondence, that is, one first guide member 600 corresponds to one elastic member 40.

[0096] In some embodiments, the first guide member 600 is a column, and the elastic member 40 is sleeved on the side wall of the column.

[0097] Specifically, in one example, the outer contour of the sidewall of the column is a continuous, uninterrupted closed ring. Exemplarily, the column can 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 discontinuous opening. Thus, when the elastic member 40 is fitted onto the sidewall of the column, the contact area between the elastic member 40 and the sidewall of the column is small, thereby reducing the frictional force between the elastic member 40 and the column, ensuring the stability of the elastic member 40'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 outside of the sidewall of the column towards the center of the column.

[0098] In other embodiments, the first guide member 600 is a column with a receiving space inside, and the elastic member 40 is received in the receiving space.

[0099] Specifically, in one example, the inner contour of the column's sidewall is a continuous, uninterrupted closed ring. Exemplarily, the accommodating space can be cylindrical, in which case the inner contour of the column's sidewall is circular. In another example, the inner contour of the column's sidewall is a non-closed ring with at least one discontinuous opening. Thus, when the elastic member 40 is accommodated within the accommodating space, the contact area between the elastic member 40 and the column's sidewall is small, thereby reducing the frictional force between the elastic member 40 and the column, ensuring the stability of the elastic member 40's expansion and contraction along the first direction (Z1 / Z2).

[0100] In some embodiments, the mating member 20 is provided with a second guide member 700, which extends along a second direction (X1 / X2). The second guide member 700 mates with the reset member 30 and guides the extension and retraction of the reset member 30. The second guide member 700 provides restriction and guidance for the deformation of the reset member 30, reducing or even preventing deformation of the reset member 30 in directions other than the second direction (X1 / X2), ensuring that the reset member 30 can provide an effective reset force to the mating member 20, so that the mating member 20 remains in the locked position. It should be noted that the number of second guide members 700 and reset members 30 is in a one-to-one correspondence; that is, one second guide member 700 corresponds to one reset member 30.

[0101] In some embodiments, the second guide member 700 is a column, and the reset member 30 is sleeved on the side wall of the column.

[0102] 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 30 is fitted onto the sidewall of the column, the contact area between the reset member 30 and the sidewall of the column is small, thereby reducing the friction between the reset member 30 and the column and ensuring the stability of the reset member 30's extension and retraction along the second direction (X1 / X2).

[0103] In other embodiments, the second guide member 700 is a column with a receiving space inside, and the reset member 30 is received in the receiving space.

[0104] Specifically, in one example, the inner contour of the column's sidewall is a continuous, uninterrupted closed ring. Exemplarily, the accommodating space can be cylindrical, in which case the inner contour of the column's sidewall is circular. In another example, the inner contour of the column's sidewall is a non-closed ring with at least one discontinuous opening. Thus, when the elastic member 40 is accommodated within the accommodating space, the contact area between the elastic member 40 and the column's sidewall is small, thereby reducing the frictional force between the elastic member 40 and the column, ensuring the stability of the elastic member 40's expansion and contraction along the first direction (Z1 / Z2).

[0105] Please refer to Figures 4 and 5. In some embodiments, the base 200 is provided with a blocking member 270 and a support member 280. One end of the reset member 30 is connected to the blocking member 270, and the other end is connected to the mating member 20. The mating member 20 is supported on the support member 280 and can move along the second direction (X1 / X2) on the support member 280.

[0106] Specifically, in some embodiments, the blocking member 270 is disposed on the bottom wall of the base 200, and the blocking member 270 includes a blocking body 271 and two connecting portions 273 located at opposite ends of the blocking body 271. The connecting portions 273 are connected to the inner side of the side wall of the base 200, and the blocking body 271 is spaced apart from the side wall of the base 200 in the second direction (X1 / X2). One end of the reset member 30 is connected to the blocking body 271, and the other end is connected to the mating member 20. Thus, when the mating member 20 moves from the locked position to the second unlocked position along the second direction (X1 / X2), the reset member 30 can generate a reset force, which can reset the mating member 20 from the second unlocked position to the locked position.

[0107] Along the height direction of the charging box 1000 (i.e., the first direction (Z1 / Z2)), the reset member 30 is located below the mating member 20, and the support member 280 can support the mating member 20. In this way, the support member 280 can guide the movement of the mating member 20 and prevent the mating member 20 from shifting during the movement. For example, the mating member 20 may shift downwards during the movement along the second direction (X1 / X2), thereby ensuring the stability of the movement of the mating member 20 and improving the stability and reliability of the button structure 100.

[0108] Furthermore, in some embodiments, the mating member 20 includes a contact surface opposite to the support member 280 (the side of the mating member 20 opposite to the support member 280), and the contact area between the support member 280 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 280 and the contact surface is equal to the area of ​​the contact surface, the friction between the mating member 20 and the support member 280 is smaller, thereby facilitating the movement of the mating member 20 relative to the support member 280 along the second direction (X1 / X2).

[0109] As described above, when the mating component 20 is subjected to the first force, the cover 300 can switch from the pressed position to the released position. In other words, to switch the cover 300 from the pressed position to the released position, the first force needs to be applied to the mating component 20. However, since the mating component 20 is located inside the base 200, it may be difficult for the user to reach into the base 200 to apply force to the mating component 20, which will affect the normal use of the charging case 1000.

[0110] In some embodiments of this application, the button structure 100 further includes a pressing member 50, which is connected to the mating member 20 and can move along the second direction (X1 / X2) together with the mating member 20. The pressing member 50 is exposed from the side wall of the base 200. Thus, the user can apply a first force to the mating member 20 without reaching into the base 200, that is, the user can apply a first force to the mating member 20 through the pressing member 50, thereby ensuring the normal use of the charging case 1000.

[0111] In some embodiments, the pressing member 50 and the mating member 20 are an integral structure, that is, the pressing member 50 and the mating member 20 can be integrally formed into a whole, which can improve the stability of the connection between the pressing member 50 and the mating member 20 and prevent the pressing member 50 from falling off the mating member 20 when the user presses it.

[0112] In other embodiments, the pressing member 50 and the mating member 20 are separate structures, that is, the pressing member 50 and the mating member 20 are two different structures. In one example, the pressing member 50 and the mating member 20 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 50 and the mating member 20 can be joined together by a non-detachable connection method, including but not limited to adhesive or welding.

[0113] In some embodiments, the base 200 is provided with a through hole 203, which penetrates the side wall and / or bottom wall of the base 200. At least a portion of the mating member 20 is located inside the base 200. The pressing member 50 passes through the through hole 203 and is connected to the mating member 20.

[0114] Specifically, in some embodiments, the shape and size of the cross-section of the pressing member 50 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 through hole 203 cut by a plane perpendicular to the second direction (X1 / X2). This not only ensures that the pressing member 50 can slide relative to the base 200 within the through hole 203 when pressed, but also reduces the gap between the pressing member 50 and the inner wall of the through hole 203, reducing or even preventing external water or dust from entering the base 200 through the gap between the pressing member 50 and the through hole 203. This ensures the normal operation of the structures within the base 200 (such as the rechargeable battery 400 and the charging circuit 500).

[0115] In some embodiments, the through hole 203 extends through the side wall of the base 200, which can improve the user's ease of use, for example, making it easier for the user to operate the charging case 1000 with one hand.

[0116] In other embodiments, the through hole 203 penetrates the bottom wall of the base 200. This reduces the possibility of water or dust entering the base 200 through the through hole 203, preventing damage to the internal structure of the base 200 and ensuring the normal operation of the charging box 1000. On the other hand, it facilitates the outflow of liquid inside the base 200 through the through hole 203, preventing liquid from accumulating inside the base 200 and causing damage to the internal structure.

[0117] In some other embodiments, the through hole 203 penetrates both the side wall and the bottom wall of the base 200. This increases the size of the through hole 203, allowing the user to insert their arm through the through hole 203 into the base 200 to apply a first force to the mating part 20, thus facilitating user operation. Furthermore, it allows liquid inside the base 200 to flow out through the through hole 203, preventing liquid accumulation inside the base 200 from damaging its internal structure.

[0118] In some embodiments, the two opposite ends of the blocking member 270 are connected to the inner side of the side wall of the base 200, and the base 200 is divided into a first cavity 2051 and a second cavity 2053. The mating member 20 and the resetting member 30 are both housed in the first cavity 2051, and the through hole 203 communicates with the first cavity 2051.

[0119] Specifically, in some embodiments, the base 200 is provided with a receiving cavity 205 for accommodating the rechargeable battery 400 and the charging circuit 500, etc. The blocking member 270 can divide the base 200 into a first cavity 2051 and a second cavity 2053; that is, the blocking member 270 can divide the receiving cavity 205 into a first cavity 2051 and a second cavity 2053. The mating member 20 and the resetting member 30 are both housed in the first cavity 2051, the through hole 203 communicates with the first cavity 2051, and the rechargeable battery 400 and the charging circuit 500, etc., are housed in the second cavity 2053. Therefore, when external liquid enters the receiving cavity 205 through the through hole 203, the blocking member 270 can block the external liquid within the first cavity 2051, preventing damage to the rechargeable battery 400 and the charging circuit 500, thereby ensuring the normal operation of the charging box 1000.

[0120] In some embodiments, the base 200 is provided with a limiting member 290, and the pressing member 50 includes an extension wall 51. The limiting member 290 partially encloses the extension wall 51 to at least limit the extension wall 51 from tilting toward the cover 300.

[0121] Specifically, in some embodiments, the limiting member 290 is disposed in the first cavity 2051, one end of the limiting member 290 can be connected to the blocking member 270, and the other end can be connected to the side wall of the base 200. The extension wall 51 can be the side wall of the pressing member 50 in the third direction Y, which is perpendicular to the first direction (Z1 / Z2) and also perpendicular to the second direction (X1 / X2).

[0122] Among them, the limiting member 290 partially encloses the extension wall 51. That is, the shape, size and outline of the side of the limiting member 290 opposite to the extension wall 51 are exactly the same or almost exactly the same as the shape, size and outline of the extension wall 51. In this way, the limiting member 290 can cooperate with the extension wall 51 to prevent the extension wall 51 from tilting towards the cover 300 and causing the movement of the pressing member 50 to deviate. This ensures the stability of the movement of the pressing member 50 and the mating member 20, thereby improving the stability and reliability of the button structure 100.

[0123] Furthermore, in some embodiments, the limiting member 290 includes a first limiting member 291 and a second limiting member 293, and the extension wall 51 includes a first extension wall 53 and a second extension wall 55. The first limiting member 291 covers at least a portion of the first extension wall 53 and at least limits the first extension wall 53 from tilting toward the cover 300. The second limiting member 293 covers at least a portion of the second extension wall 55 and at least limits the second extension wall 55 from tilting toward the cover 300.

[0124] Specifically, in some embodiments, the first extension wall 53 and the second extension wall 55 may be two opposite sidewalls of the press member 50 in the third direction Y. Compared to the restrictor 290 which only includes the first restrictor 291 or the second restrictor 293, the provision of the first restrictor 291 and the second restrictor 293 can further improve the stability of the press member 50 moving along the second direction (X1 / X2), prevent the press member 50 from tilting relative to the base 200, and improve the stability and reliability of the button structure 100 in operation.

[0125] In some embodiments, the first limiting member 291, the second limiting member 293, and the blocking member 271 together form a sub-cavity, and the through hole 203 communicates with the sub-cavity.

[0126] Specifically, in some embodiments, the sub-cavity is located within the first cavity 2051, and at least a portion of the mating member 20 is located within the sub-cavity. This further prevents external liquids from entering the second cavity 2053, which could damage the rechargeable battery 400 and charging circuit 500 in the second cavity 2053, thereby ensuring the normal operation of the charging box 1000.
