Description

Technical Field

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

[0002] In the related art, users usually use a charging case to charge or store a headset. For example, when the headset has insufficient power or is not needed, the user can store it in the charging case. The charging case includes a base and a cover, and the base and the cover are usually combined together by magnetic attraction. However, the magnetic attraction is easily affected by the external environment. For example, when the magnetic attraction decreases due to external influence, the cover may accidentally open under slight external force or vibration, affecting the stability of headset storage; for another example, when the magnetic attraction increases due to external influence, the cover may be difficult to open, affecting the access of the headset. In summary, combining the base and the cover by magnetic attraction is likely to affect the stability of the charging case. Summary of the Invention

[0047] Please refer to Figure 1 , the headphone system 3000 provided by the implementation manner of the present application includes a headphone 2000 and a charging case 1000. The charging case 1000 is used to charge the headphone 2000. Among them, since the headphone system 3000 in this implementation manner includes the charging case 1000, it can be understood that the headphone system 3000 at least includes 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 introduced below.

[0048] In some embodiments of the present application, the headphone 2000 can be worn on the user's ear and can be used in cooperation with devices such as mobile phones, computers, smart wearable devices (such as smart watches, smart bracelets, smart glasses, and smart helmets), head-mounted display devices, and virtual reality devices.

[0049] Specifically, in some embodiments, the earphone 2000 includes an air-conduction earphone and a bone-conduction earphone. Among them, the air-conduction earphone, that is, the air-conduction earphone, is an earphone that transmits sound through air vibration. The bone-conduction earphone, that is, the bone-conduction earphone, is an earphone that converts sound into different mechanical vibrations and transmits sound waves through the human skull, bony labyrinth, inner ear lymph, spiral organ, auditory center, etc.

[0050] It should be noted that the user's ear includes parts such as the external auditory canal, concha cymba, concha cavum, triangular fossa, helix, and antitragus. Among them, parts such as the concha cymba, concha cavum, and triangular fossa have a certain depth and volume in three-dimensional space. The external auditory canal is a curved duct that extends medially from the external acoustic meatus deep in the concha cymba to the tympanic membrane.

[0051] Furthermore, in some embodiments, the earphone 2000 includes a transducer assembly 2100 (including a first transducer assembly 2101 and a second transducer assembly 2103). The transducer assembly 2100 is a structure in the earphone 2000 that enables 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 in a worn state. At this time, 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 of the concha cymba, concha cavum, and triangular fossa when the earphone 2000 is in a worn state. It should be noted that in the following embodiments, only the case where the earphone 2000 is a bone-conduction earphone 2000 is taken as an example for description.

[0052] Even further, 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 rear 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 hung on the left ear and the right ear. The battery compartment 2200 can be disposed between the first ear hook assembly 2400 and the rear hook assembly 2600, and the control compartment 2300 can be disposed between the second ear hook assembly 2500 and the rear hook assembly 2600. 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. Among them, when the earphone 2000 is in a worn state, both the first transducer assembly 2101 and the second transducer assembly 2103 are located on the front side of the ear.

[0053] Please refer to Figure 1 and Figure 4, in some embodiments, the charging case 1000 includes a charging battery 400 and a charging circuit 500. When the earphone 2000 is placed in the charging case 1000, the charging circuit 500 can deliver the electric energy of the charging battery 400 to the earphone 2000 to charge the earphone 2000.

[0054] Further, please refer to Figure 2 and Figure 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.

[0055] Specifically, in some embodiments, when the first electrical connector 250 and the second electrical connector 2700 are electrically connected, functions such as electric energy transmission and data transmission can be realized between the charging case 1000 and the earphone 2000. For example, when the first electrical connector 250 and the second electrical connector 2700 are electrically connected, the charging circuit 500 can transmit the electric energy of the charging battery 400 to the battery compartment 2200 of the earphone 2000 through the first electrical connector 250 and the second electrical connector 2700, so as to charge the earphone 2000. It should be noted that, in some embodiments, the first electrical connector 250 can be at least one of devices such as spring pins and elastic sheets that can achieve electrical connection; the second electrical connector 2700 can be a device that can be electrically connected to the first electrical connector 250.

[0056] Furthermore, in some embodiments, there are multiple first electrical connectors 250 and multiple second electrical connectors 2700. 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 one-to-one correspondence.

[0057] Specifically, in some embodiments, a part of the multiple first electrical connectors 250 is used for electric energy transmission, and another part is used for signal transmission; correspondingly, a part of the multiple second electrical connectors 2700 is used for electric energy transmission, and another part is used for signal transmission. Among them, the multiple first electrical connectors 250 are arranged side by side on the charging case 1000. In this way, compared with the non-side-by-side arrangement of the multiple first electrical connectors 250 on the charging case 1000, on the one hand, the space occupied by the first electrical connectors 250 can be reduced, making the structure more compact and beneficial to the miniaturization of the charging case 1000; on the other hand, it is convenient for the alignment of the first electrical connectors 250 and the second electrical connectors 2700, improving the convenience of electrical connection.

[0058] Please refer to Figure 1 , Figure 3 and Figure 4, the charging case 1000 provided by the embodiment of the present application includes a base 200, a cover 300 and a button structure 100, and the cover 300 is movably connected to the base 200.

[0059] Among them, the base 200 is a structure in the charging case 1000 for carrying the earphone 2000. In some embodiments of the present application, the charging battery 400 and the charging circuit 500 are both arranged in the base 200. In this way, the weight of the base 200 can be increased, and the possibility of the charging case 1000 tipping over when the earphone 2000 is stored in the charging case 1000 can be reduced. The material of the base 200 includes but is not limited to plastics, aluminum alloys, copper, iron, steel, carbon fiber composite materials, etc. Exemplarily, the material of the base 200 is plastic, so that the charging case 1000 can be more lightweight and convenient for users to carry.

[0060] The cover 300 is a structure in the charging case 1000 that can cooperate with the base 200 to limit the earphone 2000. In some embodiments of the present application, the projection of the cover 300 in the height direction perpendicular to the charging case 1000 coincides with the projection of the base 200 in the height direction perpendicular to the charging case 1000; or, the projection of the cover 300 in the height direction perpendicular to the charging case 1000 is located within the projection of the base 200 in the height direction perpendicular to the charging case 1000. Among them, the material of the cover 300 includes but is not limited to plastics, aluminum alloys, copper, iron, steel, carbon fiber composite materials, etc. Exemplarily, the material of the cover 300 is plastic, so that the charging case 1000 can be more lightweight and convenient for users to carry. It can be understood that the material of the cover 300 and the material of the base 200 can be the same or different.

[0061] Movable connection refers to a connection method between two or more components, which allows relative movement between the connected components. In some embodiments of the present application, the cover 300 is movably connected to the base 200, that is, relative rotation, relative sliding or relative lifting can be achieved between the cover 300 and the base 200. In this way, when the cover 300 moves relative to the base 200, the cover 300 can switch between the pressing position and the releasing position. Among them, when the cover 300 is in the pressing position, the cover 300 can press the earphone 2000. At this time, the earphone 2000 can be stored in the charging case 1000; when the cover 300 is in the releasing position, the cover 300 can release the earphone 2000. At this time, the earphone 2000 can be taken out from the charging case 1000.

[0062] Among them, since the charging case 1000 in this embodiment includes the button structure 100, it can be understood that the charging case 1000 at least includes the same beneficial effects as the button structure 100. Therefore, for the beneficial effects of the charging case 1000, please refer to the beneficial effects of the button structure 100 introduced below.

[0063] Please refer to Figure 1 and Figure 4 For the charging case 1000, the button structure 100 provided by the embodiment of the present application is used. The button structure 100 includes a clamping member 10, a mating member 20 and a reset member 30. The clamping member 10 reciprocates between a locking position and a first unlocking position along a first direction (Z1 / Z2), and the clamping member 10 is used to connect one of the base 200 and the cover 300. The mating member 20 reciprocates between a locking position and a second unlocking position along a second direction (X1 / X2), and the mating member 20 is used to connect the other of the base 200 and the cover 300. One end of the reset member 30 is connected to the mating member 20, and the other end of the reset member 30 is connected to the base 200 or the cover 300. The reset member 30 is used to keep the mating member 20 in the locking position. Wherein, the first direction (Z1 / Z2) and the second direction (X1 / X2) intersect, and when the clamping member 10 and the mating member 20 are in the locking position, the clamping member 10 and the mating member 20 are clamped together.

[0064] Wherein, in some embodiments, the clamping member 10 is connected to the cover 300, the mating member 20 is connected to the base 200, and the reset member 30 is connected between the mating member 20 and the base 200. In other embodiments, the clamping member 10 is connected to the base 200, the mating member 20 is connected to the cover 300, and the reset member 30 is connected between the mating member 20 and the cover 300. In the embodiment of the present application, only the case where the clamping member 10 is connected to the cover 300, the mating member 20 is connected to the base 200, and the reset member 30 is connected between the mating member 20 and the base 200 is taken as an example for illustration.

[0065] Specifically, in some embodiments, when the clamping member 10 and the mating member 20 are in the locking position, the clamping member 10 and the mating member 20 are clamped (clamping fit). In this case, the cover 300 can press the earphone 2000 tightly; when the clamping member 10 is in the first unlocking position and the mating member 20 is in the second unlocking position, the clamping member 10 and the mating member 20 are disengaged (disengaged from the clamping fit). In this case, the cover 300 can release the earphone 2000.

[0066] It can be understood that in some embodiments, the reciprocating movement of the fitting 20 between the locking position and the second unlocking position along the second direction (X1 / X2) requires manual intervention, that is, manually switching the fitting 20 between the locking position and the second unlocking position along the second direction (X1 / X2); or, manually using a tool to switch the fitting 20 between the locking position and the second unlocking position along the second direction (X1 / X2). Exemplarily, when a user applies a force to the fitting 20, the fitting 20 can move from the locking position to the second unlocking position along the second direction (X1 / X2) relative to the base 200; when the user does not apply a force to the fitting 20, the fitting 20 can move from the second unlocking position to the locking position along the second direction (X1 / X2) under the action of the resetting member 30. Wherein, when the fitting 20 moves along the second direction (X1 / X2), the base 200 does not move along the second direction (X1 / X2) together with the fitting 20. In other words, the fitting 20 can move relative to the base 200 along the second direction (X1 / X2).

[0067] The reciprocating movement of the engaging member 10 between the locking position and the first unlocking position along the first direction (Z1 / Z2) requires manual intervention, that is, manually switching the engaging member 10 between the locking position and the first unlocking position along the first direction (Z1 / Z2); or, manually using a tool to switch the engaging member 10 between the locking position and the first unlocking position along the first direction (Z1 / Z2). Exemplarily, when a user applies a force to the engaging member 10, the engaging member 10 can move from the first unlocking position to the locking position along the first direction (Z1 / Z2); when the user does not apply a force to the engaging member 10 and the fitting 20 is in the second unlocking position, the engaging member 10 can move from the locking position to the first unlocking position along the first direction (Z1 / Z2). Wherein, when the engaging member 10 moves along the first direction (Z1 / Z2), the cover 300 moves along the first direction (Z1 / Z2) together with the engaging member 10.

[0068] 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 included angle between the two can be any angle between (0°, 180°), for example, the included angle between the two can be 15°, 30°, 45°, 60°, 75°, 100°, 115°, 120°, or 135°, etc. In the embodiments of the present application, only the example where the first direction (Z1 / Z2) and the second direction (X1 / X2) are perpendicular is used for illustration.

[0069] In the button structure 100 according to the embodiments of the present application, the engaging member 10 reciprocates between the locking position and the first unlocking position along the first direction (Z1 / Z2). The engaging member 10 is connected to one of the base 200 and the cover 300. The cooperating member 20 reciprocates between the locking position and the second unlocking position along the second direction (X1 / X2). The cooperating member 20 is connected to the other of the base 200 and the cover 300. When the engaging member 10 and the cooperating member 20 are in the locking position, the engaging member 10 and the cooperating member 20 are snap-fitted. Thus, compared with the charging case in the related art, the setting of the button structure 100 can prevent the relative movement between the cover 300 and the base 200 from being unstable due to the change of the magnetic attraction force, thereby improving the stability of the charging case 1000.

[0070] The button structure 100 will be further explained below with reference to the accompanying drawings.

[0071] Please refer to Figure 3 and Figure 4 , in some embodiments, the cover 300 can move up and down relative to the base 200 to switch between the pressing position and the releasing position. When the cover 300 is in the pressing position, the engaging member 10 and the cooperating member 20 are in the locking position. When the cover 300 is in the releasing position, the engaging member 10 is in the first unlocking position and the cooperating member 20 is in the second unlocking position. The first direction (Z1 / Z2) is the lifting direction of the cover 300.

[0072] Specifically, in some embodiments, the pressing position can be: along the lifting direction of the cover 300 (the same as the height direction of the charging case 1000), the limit position that the cover 300 can move downward relative to the base 200 (the cover 300 moves relative to the base 200 along the direction from the cover 300 to the base 200); the releasing position can be: along the lifting direction of the cover 300, the limit position that the cover 300 can move upward relative to the base 200 (the cover 300 moves relative to the base 200 along the direction from the base 200 to the cover 300).

[0073] More specifically, please combine Figure 1, in some embodiments, when the cover 300 is in the pressed position, the cover 300 can press the earphone 2000, thereby realizing the limitation of the earphone 2000 and preventing the earphone 2000 from moving or shaking in the charging case 1000, and improving the stability of the earphone 2000 stored in the charging case 1000. At the same time, when the cover 300 is in the pressed position, it can also prevent the earphone 2000 from moving or shaking in the charging case 1000, which may cause poor contact between the charging end of the earphone 2000 (i.e., the second electrical connector 2700) and the charging end of the charging case 1000 (i.e., the first electrical connector 250), thereby improving the charging stability of the charging case 1000 for the earphone 2000 and ensuring the normal realization 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 taken out from the charging case 1000.

[0074] Further, in some embodiments, the cover 300 and the base 200 together form an earphone compartment 201 for accommodating the earphone 2000.

[0075] Specifically, in some embodiments, when the engaging member 10 moves from the locked position to the first unlocking position and the cooperating member 20 moves from the locked position to the second unlocking position, the cover 300 switches from the pressed position to the released 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 taken out from the earphone compartment 201. When the engaging member 10 moves from the first unlocking position to the locked position and the cooperating member 20 moves from the second unlocking position to the locked position, the cover 300 switches from the released position to the pressed 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 in the earphone compartment 201, and the charging case 1000 can charge the earphone 2000.

[0076] 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 that are 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 for the earphone 2000 to be placed into the earphone compartment 201.

[0077] 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 that are connected in sequence. Among them, 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. In this way, when the cover 300 rises relative to the base 200, the earphone 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 of the earphone compartment), so that the charging case 1000 can charge and store the earphone 2000.

[0078] In some embodiments of the present application, the first side 2011 of the earphone compartment is closed, and the second side 2013, the third side 2015, and the fourth side 2017 of the earphone compartment are open. At this time, when the cover 300 rises relative to the base 200, along the direction from the second side 2013 to the fourth side 2017 of the earphone compartment, the earphone 2000 can be placed into the earphone compartment 201 through the second side 2013 of the earphone compartment; or, along the direction from the third side 2015 to the first side 2011 of the earphone compartment, the earphone 2000 can be placed into the earphone compartment 201 through the third side 2015 of the earphone compartment.

[0079] Furthermore, please refer 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 towards the base 200. The base 200 includes a base body 210 and a connecting member 230. The connecting member 230 extends from the base body 210 towards the cover 300. A part of the extension 330 extends into the connecting member 230 and can move up and down relative to the connecting member 230, so that the cover 300 can be switched between a pressed position and a released position.

[0080] Specifically, in some embodiments, a part of the extension 330 can extend into the connecting member 230 and can move up and down relative to the connecting member 230. In this way, the connecting member 230 can guide and limit the up and down movement of the extension 330, preventing the extension 330 from getting stuck during the up and down movement, thereby improving the stability of the up and down movement of the cover 300 relative to the base 200. It can be understood that the projection of the extension 330 on the base body 210 is located within the connecting member 230, so as to ensure that a part of the extension 330 can extend into the connecting member 230, and further enable the extension 330 to move up and down relative to the connecting member 230.

[0081] More specifically, in some embodiments, the seat body 210 includes an interconnected seat main body 211 and an upper cover 213, and both the rechargeable battery 400 and the charging circuit 500 are disposed within the seat body 210. Among them, the seat main body 211 and the upper cover 213 are detachably connected, so as to facilitate the installation of the rechargeable battery 400 and the charging circuit 500.

[0082] In some embodiments, the button structure 100 further includes an elastic member 40, the elastic member 40 is connected between the base 200 and the cover body 300 and extends along the first direction (Z1 / Z2), and the reset member 30 is connected between the engaging member 20 and the base 200 and extends along the second direction (X1 / X2). When the cover body 300 is in the pressed position, the elastic member 40 has a first length and the reset member 30 is in a first state; when the cover body 300 is in the released position, the elastic member 40 has a second length and the reset member 30 is in a second state, and the second length is greater than the first length.

[0083] Specifically, in some embodiments, since when the cover body 300 is switched 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 body 300 is in the released position is greater than the first length of the elastic member 40 when the cover body 300 is in the pressed position, therefore, when the cover body 300 is in the pressed position, the elastic member 40 is in a compressed state; when the cover body 300 is in the released position, the elastic member 40 is in a normal state (a state where it is not stretched or compressed) or a compressed state (at this time, the compression amount of the elastic member 40 is less than the compression amount of the elastic member 40 when the cover body 300 is in the pressed position). Thus, during the process of the cover body 300 being switched from the pressed position to the released position, the elastic member 40 can provide an elastic force for the cover body 300, so as to ensure that the cover body 300 can smoothly rise relative to the base 200.

[0084] In some embodiments, during the process of the cover body 300 being switched from the pressed position to the released position, the reset member 30 sequentially switches between the first state, the second state, and the first state. During the process of the cover body 300 being switched from the released position to the pressed position, the reset member 30 sequentially switches between the first state, the second state, and the first state, and 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.

[0085] Specifically, in some embodiments, when the reset member 30 is in the first state, both the engaging member 10 and the engaging member 20 are in the locked position; when the reset member 30 is in the second state, the engaging member 10 is in the first unlocking position and the engaging member 20 is in the second unlocking position.

[0086] Wherein, when the cover 300 is switched from the pressing position to the release position, the reset member 30 is sequentially switched between the first state, the second state, and the first state. That is, the cooperating member 20 is sequentially switched between the locking position, the second unlocking position, and the locking position. When the cooperating member 20 moves from the locking position to the second unlocking position, the engagement between the cooperating member 20 and the engaging member 10 is released, and the engaging member 10 moves from the locking position to the first unlocking position. It can be 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 cooperating member 20, and the reset force is used to keep the cooperating member 20 in the locking position.

[0087] Further, in some embodiments, when the cover 300 is in the pressing position and the cooperating member 20 is subjected to a first acting force, the cooperating member 20 can move in the positive direction X1 of the second direction (X1 / X2). The reset member 30 is switched from the first state to the second state, and the elastic member 40 elongates and pushes the cover 300 to move in the upward direction of the cover 300. When the first acting force disappears, the reset member 30 is switched from the second state to the first state, and the cooperating member 20 moves in the reverse direction X2 of the second direction (X1 / X2) and is located below the engaging member 10.

[0088] Specifically, in some embodiments, when the cooperating member 20 is subjected to a first acting force and the cooperating member 20 moves in the positive direction X1 of the second direction (X1 / X2), the reset member 30 generates a reset force, and the cooperating member 20 moves from the locking position to the second unlocking position to release the engagement between the cooperating 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 acting force disappears, the reset force of the reset member 30 can cause the cooperating member 20 to move in the reverse direction X2 of the second direction (X1 / X2). That is, the reset force can cause the cooperating member 20 to move from the second unlocking position to the locking position. In this case, the cooperating member 20 is located below the engaging member 10. Thus, when the cooperating member 20 is subjected to a first acting force, the cover 300 can be switched from the pressing position to the release position.

[0089] In some embodiments, when the cover 300 is in the release position and the cover 300 is subjected to a second acting 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 cooperating member 20 to move in the positive direction X1 of the second direction (X1 / X2), and the reset member 30 is switched from the first state to the second state. When the engaging member 10 is in the locking position, the cooperating member 20 moves in the reverse direction X2 of the second direction (X1 / X2), and the reset member 30 is switched from the second state to the first state.

[0090] Specifically, in some embodiments, when the cover 300 is subjected to a second force and the cover 300 moves in the downward direction of the cover 300 (the direction from the cover 300 to the base 200), the engaging member 10 generates a thrust on the mating member 20 to push the mating member 20 to move in the positive direction X1 of the second direction (X1 / X2). At this time, the restoring member 30 generates a restoring force, and the mating member 20 moves from the locked position to the second unlocking position; when the engaging member 10 moves to the locked position in the downward direction of the cover 300, the engaging member 10 does not generate a thrust on the mating member 20, and the restoring force of the restoring member 30 can cause the mating member 20 to move in the reverse direction X2 of the second direction (X1 / X2), that is, the restoring force can cause the mating member 20 to move from the second unlocking position to the locked position. In this case, the engaging member 10 and the mating member 20 are snap-fitted. Thus, when the cover 300 is subjected to a second force, the cover 300 can be switched from the release position to the pressing position.

[0091] Please refer to Figures 3 to 5 , in some embodiments, the first force applied to the mating member 20 is a pressure, the length of the restoring member 30 in the first state is greater than the length of the restoring 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 reverse direction X2 of the second direction (X1 / X2) is the direction towards the outside of the base 200.

[0092] Specifically, please combine Figure 4 and Figure 5 , in some embodiments, when the engaging member 10 and the mating member 20 are snap-fitted, the restoring member 30 is located on the side of the mating member 20 opposite to the engaging member 10. At this time, the restoring member 30 can be a compression spring. When the restoring member 30 is in the first state, the mating member 20 is located at the locked position, and the restoring member 30 is in a normal state (a state not stretched or compressed) or in a first compressed state; when the restoring member 30 is in the second state, the mating member 20 is located at the second unlocking position, and the restoring member 30 is in a second compressed state. Among them, the length of the restoring member 30 in the first compressed state is greater than the length of the restoring member 30 in the second compressed state.

[0093] Please refer to Figure 3 and Figure 7 , in some embodiments, the first force applied to the mating member 20 is a tensile force, the length of the restoring member 30 in the first state is less than the length of the restoring 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 reverse direction X2 of the second direction (X1 / X2) is the direction towards the inside of the base 200.

[0094] Specifically, please combine Figure 7, 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. At this time, the reset member 30 can be a tension spring. When the reset member 30 is in the first state, the mating member 20 is located at the locking position, and the reset member 30 is in the normal state (the state of not being stretched or compressed) or the first stretched state; when the reset member 30 is in the second state, the mating member 20 is located at the second unlocking position, and the reset member 30 is in the second stretched state. Among them, the length of the reset member 30 in the first stretched state is less than the length of the reset member 30 in the second stretched state.

[0095] Please refer to Figures 3 to 5 , and in combination with Figure 6 or Figure 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 cooperates with the engaging portion 13 to enable the mating member 20 to be engaged with the engaging member 10.

[0096] Specifically, in some embodiments, when both the engaging member 10 and the mating member 20 are located at the locking position, the hook portion 23 cooperates with the engaging portion 13; when the engaging member 10 is located at the first unlocking position and the mating member 20 is located at the second unlocking position, the hook portion 23 is disengaged from the engaging portion 13.

[0097] 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 formed as a whole by an integral molding method. In this way, the connection stability between the mating body 21 and the hook portion 23 can be improved, and the hook portion 23 can be prevented from falling off the mating body 21 when the hook portion 23 cooperates with the engaging portion 13, thereby ensuring the stability and reliability of the operation of the button structure 100.

[0098] In other embodiments, the mating body 21 and the hook portion 23 are a split structure, that is, the mating body 21 and the hook portion 23 are two different structures. In one example, the mating body 21 and the hook portion 23 can be combined together by a detachable connection method, and the detachable connection method includes but is not limited to snap connection or bolt connection, etc. In another example, the mating body 21 and the hook portion 23 can be combined together by a non-detachable connection method, and the non-detachable connection method includes but is not limited to bonding or welding, etc. It can be understood that the connection method between the engaging body 11 and the engaging portion 13 is basically the same as the connection method between the mating body 21 and the hook portion 23, and will not be elaborated here.

[0099] Further, in some embodiments, a first inclined surface 131 is provided on the engaging portion 13, and a second inclined surface 231 is provided on the engaging hook portion 23. During the process of the cover 300 switching from the release position to the pressing position, the first inclined surface 131 abuts against the second inclined surface 231.

[0100] If the first inclined surface 131 is not provided on the engaging portion 13 and the second inclined surface 231 is not provided on the engaging hook portion 23, then when the engaging portion 13 moves along the descending direction of the cover 300 so that the engaging portion 13 abuts against the engaging hook portion 23, the engaging portion 13 can only generate a thrust on the engaging hook portion 23 along the first direction (Z1 / Z2) (i.e., the lifting direction of the charging case 1000), and this thrust cannot push the engaging hook portion 23 to move along the second direction (X1 / X2). Thus, the provision of the first inclined surface 131 and the second inclined surface 231 enables the engaging portion 13 to generate a thrust on the engaging hook portion 23 when the first inclined surface 131 abuts against the second inclined surface 231, and the component force of this thrust in the second direction (X1 / X2) can push the engaging hook portion 23 to move along the second direction (X1 / X2).

[0101] Specifically, in some embodiments, the angle between the first inclined surface 131 and the positive direction X1 of the second direction (X1 / X2) is a first acute angle, and the angle between the second inclined surface 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 magnitudes of the first acute angle and the second acute angle may be the same or different.

[0102] In some embodiments, a first flat surface 133 is provided on the engaging portion 13, and a second flat surface 233 is provided on the engaging hook portion 23. When the cover 300 is in the pressing position, the first flat surface 133 abuts against the second flat surface 233. Among them, both the first flat surface 133 and the second flat surface 233 can be perpendicular to the first direction (Z1 / Z2). Thus, the abutment of the first flat surface 133 and the second flat surface 233 can achieve the snap-fit between the engaging portion 13 and the mating portion, thereby restricting the lifting of the cover 300 relative to the base 200.

[0103] Please refer to Figure 4 and Figure 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), cooperates with the elastic member 40, and is used to guide the expansion and contraction of the elastic member 40. Among them, the first guide member 600 can provide limitation and guidance for the deformation of the elastic member 40, reduce or even avoid the deformation of the elastic member 40 in a direction other than the first direction (Z1 / Z2), and ensure that the elastic member 40 can provide an effective elastic force to the cover 300, so that the cover 300 can be switched from the pressed position to the released position. It should be noted that the quantity relationship between the first guide member 600 and the elastic member 40 is one-to-one correspondence, that is, one first guide member 600 corresponds to one elastic member 40.

[0104] In some embodiments, the first guide member 600 is a cylinder, and the elastic member 40 is sleeved on the side wall of the cylinder.

[0105] Specifically, in one example, the outer contour of the side wall of the cylinder is a continuous and unbroken closed ring. Exemplarily, the cylinder can be cylindrical, and at this time, the outer contour of the side wall of the cylinder is circular. In another example, the outer contour of the side wall of the cylinder is a non-closed ring with at least one break. Thus, when the elastic member 40 is sleeved on the side wall of the cylinder, the contact area between the elastic member 40 and the side wall of the cylinder is small, so that the friction between the elastic member 40 and the cylinder can be reduced, and the stability of the elastic member 40 expanding and contracting along the first direction (Z1 / Z2) can be ensured. Exemplarily, at least one groove is provided on the cylinder, and the groove depresses from the outer side of the side wall of the cylinder towards the center of the cylinder.

[0106] In some other embodiments, the first guide member 600 is a cylinder, and an accommodating space is provided inside the cylinder, and the elastic member 40 is accommodated in the accommodating space.

[0107] Specifically, in one example, the inner contour of the side wall of the cylinder is a continuous and unbroken closed ring. Exemplarily, the accommodating space can be cylindrical, and at this time, the inner contour of the side wall of the cylinder is circular. In another example, the inner contour of the side wall of the cylinder is a non-closed ring with at least one break. Thus, when the elastic member 40 is accommodated in the accommodating space, the contact area between the elastic member 40 and the side wall of the cylinder is small, so that the friction between the elastic member 40 and the cylinder can be reduced, and the stability of the elastic member 40 expanding and contracting along the first direction (Z1 / Z2) can be ensured.

[0108] In some embodiments, a second guiding member 700 is provided on the mating member 20. The second guiding member 700 extends along a second direction (X1 / X2). The second guiding member 700 cooperates with the resetting member 30 and is used to guide the telescopic movement of the resetting member 30. Among them, the second guiding member 700 can provide limitation and guidance for the deformation of the resetting member 30, reduce or even avoid the deformation of the resetting member 30 in a direction other than the second direction (X1 / X2), and ensure that the resetting member 30 can provide an effective reset force for the mating member 20 so that the mating member 20 is maintained at the locked position. It should be noted that the quantity relationship between the second guiding member 700 and the resetting member 30 is one-to-one correspondence, that is, one second guiding member 700 corresponds to one resetting member 30.

[0109] In some embodiments, the second guiding member 700 is a cylinder, and the resetting member 30 is sleeved on the side wall of the cylinder.

[0110] Specifically, in one example, the outer contour of the side wall of the cylinder is a continuous and unbroken closed ring. Exemplarily, the cylinder can be a cylindrical shape. At this time, the outer contour of the side wall of the cylinder is a circle. In another example, the outer contour of the side wall of the cylinder is a non-closed ring with at least one break. Thus, when the resetting member 30 is sleeved on the side wall of the cylinder, the contact area between the resetting member 30 and the side wall of the cylinder is small, so that the friction between the resetting member 30 and the cylinder can be reduced, and the stability of the telescopic movement of the resetting member 30 along the second direction (X1 / X2) can be ensured.

[0111] In other embodiments, the second guiding member 700 is a cylinder, and an accommodating space is provided in the cylinder. The resetting member 30 is accommodated in the accommodating space.

[0112] Specifically, in one example, the inner contour of the side wall of the cylinder is a continuous and unbroken closed ring. Exemplarily, the accommodating space can be a cylindrical shape. At this time, the inner contour of the side wall of the cylinder is a circle. In another example, the inner contour of the side wall of the cylinder is a non-closed ring with at least one break. Thus, when the elastic member 40 is accommodated in the accommodating space, the contact area between the elastic member 40 and the side wall of the cylinder is small, so that the friction between the elastic member 40 and the cylinder can be reduced, and the stability of the telescopic movement of the elastic member 40 along the first direction (Z1 / Z2) can be ensured.

[0113] Please continue to refer to Figure 4 and Figure 5 , in some embodiments, a blocking member 270 and a supporting member 280 are provided in the base 200. One end of the resetting 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 carried on the supporting member 280 and can move along the second direction (X1 / X2) on the supporting member 280.

[0114] 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. In the second direction (X1 / X2), the blocking body 271 is spaced apart from the side wall of the base 200. 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 unlocking position along the second direction (X1 / X2), the reset member 30 can generate a reset force, and this reset force can reset the mating member 20 from the second unlocking position to the locked position.

[0115] Among them, along the height direction of the charging case 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. Thus, the support member 280 can guide the movement of the mating member 20, preventing the mating member 20 from shifting during movement. For example, when the mating member 20 moves along the second direction (X1 / X2), it may shift downward, thereby ensuring the stability of the movement of the mating member 20 and improving the stability and reliability of the operation of the button structure 100.

[0116] Further, 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. Thus, compared with the case where the contact area between the support member 280 and the contact surface is equal to the area of the contact surface, the frictional force 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).

[0117] As can be seen from the above, when the mating member 20 is subjected to a first acting force, the cover 300 can be switched from the pressed position to the released position. In other words, in order to switch the cover 300 from the pressed position to the released position, a first acting force needs to be applied to the mating member 20. However, since the mating member 20 is disposed within the base 200, it may be difficult for the user to reach into the base 200 to apply a force to the mating member 20, which will affect the normal use of the charging case 1000.

[0118] In some embodiments of the present application, the button structure 100 further includes a pressing member 50. The pressing member 50 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 acting force to the mating member 20 without reaching into the base 200, that is, the user can apply a first acting force to the mating member 20 through the pressing member 50, thereby ensuring the normal use of the charging case 1000.

[0119] In some embodiments, the pressing member 50 and the mating member 20 are of an integral structure, that is, the pressing member 50 and the mating member 20 can be formed as a whole by integral molding. In this way, the connection stability between the pressing member 50 and the mating member 20 can be improved, and it can be prevented that the pressing member 50 falls off from the mating member 20 when the user presses it.

[0120] In other embodiments, the pressing member 50 and the mating member 20 are of a split structure, 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 combined together by a detachable connection method, and the detachable connection methods include but are not limited to snap connection or bolt connection, etc. In another example, the pressing member 50 and the mating member 20 can be combined together by a non-detachable connection method, and the non-detachable connection methods include but are not limited to bonding or welding, etc.

[0121] In certain embodiments, a through hole 203 is provided on the base 200. The through hole 203 penetrates the side wall and / or the bottom wall of the base 200. At least a part of the mating member 20 is located inside the base 200, and the pressing member 50 passes through the through hole 203 and is connected to the mating member 20.

[0122] Specifically, in certain embodiments, the shape and size of the cross-section of the pressing member 50 intercepted by a plane perpendicular to the second direction (X1 / X2) are substantially the same as the shape and size of the cross-section of the through hole 203 intercepted by a plane perpendicular to the second direction (X1 / X2). Thus, not only can it be ensured that the pressing member 50 can slide relative to the base 200 in the through hole 203 when being pressed, but also the gap between the pressing member 50 and the inner wall of the through hole 203 can be reduced, and the entry of external water or dust into the base 200 through the gap between the pressing member 50 and the through hole 203 can be reduced or even avoided, so as to ensure the normal operation of the structures (such as the rechargeable battery 400 and the charging circuit 500, etc.) inside the base 200.

[0123] In some embodiments, the through hole 203 penetrates the side wall of the base 200, so as to improve the convenience of use for the user. For example, it is convenient for the user to operate the charging case 1000 with one hand.

[0124] In other embodiments, the through hole 203 penetrates the bottom wall of the base 200. On the one hand, the possibility of external water or dust entering the base 200 through the through hole 203 can be reduced, the structures inside the base 200 can be prevented from being damaged, and the normal operation of the charging case 1000 can be ensured; on the other hand, the liquid inside the base 200 can be conveniently discharged through the through hole 203, and it can be ensured that the liquid accumulates inside the base 200 and causes damage to the structures inside the base 200.

[0125] In still other embodiments, the through hole 203 penetrates through the side wall and the bottom wall of the base 200. On the one hand, this can increase the size of the through hole 203, ensuring that the user can extend into the base 200 through the through hole 203 to apply a first force to the fitting 20, facilitating user operation; on the other hand, it can facilitate the liquid inside the base 200 to flow out through the through hole 203, ensuring that the structure inside the base 200 is not damaged due to the accumulation of liquid inside the base 200.

[0126] In some embodiments, both 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 chamber 2051 and a second chamber 2053. The fitting 20 and the reset member 30 are both accommodated in the first chamber 2051, and the through hole 203 communicates with the first chamber 2051.

[0127] Specifically, in some embodiments, the base 200 is provided with a receiving cavity 205 for accommodating structures such as a rechargeable battery 400 and a charging circuit 500. The blocking member 270 can divide the base 200 into a first chamber 2051 and a second chamber 2053, that is, the blocking member 270 can divide the receiving cavity 205 into a first chamber 2051 and a second chamber 2053. Among them, the fitting 20 and the reset member 30 are both accommodated in the first chamber 2051, and the through hole 203 communicates with the first chamber 2051. Structures such as the rechargeable battery 400 and the charging circuit 500 are all accommodated in the second chamber 2053. Thus, 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 chamber 2051, preventing the liquid from damaging structures such as the rechargeable battery 400 and the charging circuit 500, thereby ensuring the normal operation of the charging case 1000.

[0128] In some embodiments, a restricting member 290 is provided inside the base 200. The pressing member 50 includes an extending wall 51, and the restricting member 290 semi - wraps the extending wall 51 to at least restrict the extending wall 51 from tilting towards the cover 300.

[0129] Specifically, in some embodiments, the restricting member 290 is disposed in the first chamber 2051. One end of the restricting 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 extending wall 51 can be the side wall of the pressing member 50 in the third direction Y, and the third direction Y is perpendicular to the first direction (Z1 / Z2) and also perpendicular to the second direction (X1 / X2).

[0130] Among them, the limiting member 290 semi - wraps the extending wall 51, that is, the shape, size and contour of the side of the limiting member 290 opposite to the extending wall 51 are exactly the same or almost exactly the same as the shape, size and contour of the extending wall 51. In this way, the limiting member 290 can cooperate with the extending wall 51 to prevent the extending wall 51 from tilting towards the cover body 300, resulting in the deviation of the movement of the pressing member 50. Thus, the stability of the movement of the pressing member 50 and the cooperating member 20 can be ensured, and further the stability and reliability of the operation of the key structure 100 can be improved.

[0131] Further, in some embodiments, the limiting member 290 includes a first limiting member 291 and a second limiting member 293, and the extending wall 51 includes a first extending wall 53 and a second extending wall 55. The first limiting member 291 covers at least a part of the first extending wall 53 and at least limits the first extending wall 53 from tilting towards the cover body 300. The second limiting member 293 covers at least a part of the second extending wall 55 and at least limits the second extending wall 55 from tilting towards the cover body 300.

[0132] Specifically, in some embodiments, the first extending wall 53 and the second extending wall 55 can be two side walls of the pressing member 50 that are opposite to each other in the third direction Y. Compared with the case where the limiting member 290 only includes the first limiting member 291 or the second limiting member 293, the arrangement of the first limiting member 291 and the second limiting member 293 can further improve the stability of the movement of the pressing member 50 along the second direction (X1 / X2), prevent the pressing member 50 from tilting relative to the base 200, and improve the stability and reliability of the operation of the key structure 100.

[0133] In some embodiments, the first limiting member 291, the second limiting member 293 and the blocking member 271 together enclose a sub - cavity, and the through - hole 203 communicates with the sub - cavity.

[0134] Specifically, in some embodiments, the sub - cavity is located in the first cavity 2051, and at least a part of the cooperating member 20 is located in the sub - cavity. Thus, it can further prevent external liquid from entering the second cavity 2053, resulting in damage to structures such as the rechargeable battery 400 and the charging circuit 500 in the second cavity 2053, and thereby ensure the normal operation of the charging case 1000.
