Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and more specifically, to a button structure, a charging box, and an earphone system. Background Art

[0002] In the related art, users usually use a charging box to realize functions such as charging or storing earphones. For example, when the earphones are low on power or do not need to be used, users can store them in the charging box. The charging box includes a base and a cover, and the base and the cover are usually combined together by magnetic attraction. However, the magnetic attraction force is easily affected by the outside world. For example, when the magnetic attraction force is reduced due to external influences, the cover may accidentally open under slight external force or vibration, affecting the stability of the earphone storage; for another example, when the magnetic attraction force is increased due to external influences, the cover may be difficult to open, affecting the placement and removal of the earphones. In summary, the base and the cover are combined together by magnetic attraction, which is easy to affect the stability of the charging box. Utility Model Content

[0047] See also Figure 1 The earphone system 3000 provided in the embodiment of the present application includes an earphone 2000 and a charging box 1000. The charging box 1000 is used to charge the earphone 2000. Since the earphone system 3000 in this embodiment includes the charging box 1000, it can be understood that the earphone system 3000 includes at least the same beneficial effects as the charging box 1000. Therefore, for the beneficial effects of the earphone system 3000, please refer to the beneficial effects of the charging box 1000 described below.

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

[0049] Specifically, in some embodiments, the headphones 2000 include air conduction headphones and bone conduction headphones. Air conduction headphones, or air conduction headphones, are headphones that transmit sound through air vibrations. Bone conduction headphones, or bone conduction headphones, are headphones that convert sound into different mechanical vibrations and transmit sound waves through the human skull, bony labyrinth, inner ear lymph, circumflex organ, auditory center, and the like.

[0050] It should be noted that the user's ear includes the external auditory canal, cavum concha, cymba concha, triangular fossa, helix, and antitragus. The cavum concha, cymba concha, and triangular fossa have a certain depth and volume in three-dimensional space. The external auditory canal is a curved tube that extends from the external auditory meatus deep in the cavum concha to the eardrum.

[0051] Furthermore, in certain 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 the structure within the earphone 2000 that enables the user to hear sound. In one example, if the earphone 2000 is a bone conduction earphone 2000, the transducer assembly 2100 is configured to be located in front of the ear when the earphone 2000 is worn, so that the transducer assembly 2100 does not block the external auditory canal. In another example, if 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 cavum conchae, the cymba conchae, and the triangular fossa when the earphone 2000 is worn. It should be noted that the embodiments described below are based on the example of a bone conduction earphone 2000.

[0052] Furthermore, in some embodiments, the earphones 2000 include a battery compartment 2200, a control compartment 2300, a first earhook component 2400, a second earhook component 2500, and a back-hook component 2600 disposed between the first earhook component 2400 and the second earhook component 2500. The first earhook component 2400 and the second earhook component 2500 are hung on the left ear and the right ear, respectively. The battery compartment 2200 can be disposed between the first earhook component 2400 and the back-hook component 2600, and the control compartment 2300 can be disposed between the second earhook component 2500 and the back-hook component 2600. The first transducer component 2101 and the second transducer component 2103 are both used to convert electrical signals into mechanical vibrations so that the user can hear sounds. When the earphones 2000 are in a worn state, the first transducer component 2101 and the second transducer component 2103 are both located on the front side of the ear.

[0053] See also Figure 1 and Figure 4In some embodiments, the charging box 1000 includes a rechargeable battery 400 and a charging circuit 500. When the earphone 2000 is placed in the charging box 1000, the charging circuit 500 can transmit the power of the rechargeable battery 400 to the earphone 2000 to charge the earphone 2000.

[0054] Furthermore, please combine Figure 2 and Figure 3 In some embodiments, the charging box 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 box 1000, the first electrical connector 250 and the second electrical connector 2700 are electrically connected.

[0055] Specifically, in certain embodiments, when the first electrical connector 250 and the second electrical connector 2700 are electrically connected, functions such as power and data transmission can be achieved between the charging case 1000 and the earphones 2000. For example, when the first electrical connector 250 and the second electrical connector 2700 are electrically connected, the charging circuit 500 can transfer power from the rechargeable battery 400 to the battery compartment 2200 of the earphones 2000 through the first electrical connector 250 and the second electrical connector 2700, thereby charging the earphones 2000. It should be noted that in certain embodiments, the first electrical connector 250 can be at least one of a spring pin and a spring element capable of achieving electrical connection; and the second electrical connector 2700 can be a device capable of electrically connecting to the first electrical connector 250.

[0056] 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 box 1000, the multiple first electrical connectors 250 and the multiple second electrical connectors 2700 are electrically connected one by one.

[0057] 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 box 1000. Compared to a case where the plurality of first electrical connectors 250 are not arranged side by side on the charging box 1000, on the one hand, the space occupied by the first electrical connectors 250 can be reduced, making the structure more compact and facilitating the miniaturization of the charging box 1000; on the other hand, the alignment of the first electrical connectors 250 and the second electrical connectors 2700 can be facilitated, thereby improving the convenience of electrical connection.

[0058] See also Figure 1 、 Figure 3 and Figure 4The charging box 1000 provided in 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 box 1000 for carrying the earphones 2000. In some embodiments of the present application, the rechargeable battery 400 and the charging circuit 500 are both disposed in the base 200. This can make the base 200 heavier and reduce the possibility of the charging box 1000 tipping over when the earphones 2000 are stored in the charging box 1000. The material of the base 200 includes but is not limited to plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite materials. For example, the base 200 is made of plastic, which can make the charging box 1000 lighter and easier for users to carry.

[0060] The cover 300 is a structure in the charging box 1000 that can cooperate with the base 200 to restrict the earphones 2000. In some embodiments of the present application, the projection of the cover 300 in the direction perpendicular to the height of the charging box 1000 coincides with the projection of the base 200 in the direction perpendicular to the height of the charging box 1000; or, the projection of the cover 300 in the direction perpendicular to the height of the charging box 1000 is located within the projection of the base 200 in the direction perpendicular to the height of the charging box 1000. The material of the cover 300 includes but is not limited to plastic, aluminum alloy, copper, iron, steel and carbon fiber composite materials. Exemplarily, the material of the cover 300 is plastic, which makes the charging box 1000 lighter and easier for users to carry. It is understandable that the material of the cover 300 may be the same as or different from that of the base 200.

[0061] An active connection refers to a connection method between two or more parts, which allows relative movement between the connected parts. In some embodiments of the present application, the cover 300 is movably connected to the base 200, that is, the cover 300 and the base 200 can achieve relative rotation, relative sliding or relative lifting. In this way, when the cover 300 moves relative to the base 200, the cover 300 can switch between a pressing position and a release position. When the cover 300 is in the pressing position, the cover 300 can press the earphone 2000, and at this time, the earphone 2000 can be stored in the charging box 1000; when the cover 300 is in the release position, the cover 300 can release the earphone 2000, and at this time, the earphone 2000 can be taken out of the charging box 1000.

[0062] Among them, since the charging box 1000 in this embodiment includes a button structure 100, it can be understood that the charging box 1000 at least includes 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.

[0063] See also Figure 1 and Figure 4 The key structure 100 provided in the embodiment of the present application is used for a charging box 1000. The key structure 100 includes a locking member 10, a matching member 20 and a reset member 30. The locking member 10 reciprocates between a locked position and a first unlocked position along a first direction (Z1 / Z2), and the locking member 10 is used to connect one of the base 200 and the cover 300. The matching member 20 reciprocates between a locked position and a second unlocked position along a second direction (X1 / X2), and the matching member 20 is used to connect the other of the base 200 and the cover 300. The reset member 30 is connected between the matching member 20 and the base 200, or between the matching member 20 and the cover 300, and the reset member 30 is used to keep the matching member 20 in the locked position. The first direction (Z1 / Z2) and the second direction (X1 / X2) intersect, and when the locking member 10 and the matching member 20 are in the locked position, the locking member 10 and the matching member 20 are matched. It should be noted that, in some embodiments, when the engaging member 10 and the matching member 20 are in the locked position, the engaging member 10 and the matching member 20 are engaged.

[0064] 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 reset 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 reset member 30 is connected between the mating member 20 and the cover 300. In the embodiments of the present application, only the embodiment in which the engaging 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 described as an example.

[0065] 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 with each other, in which case the cover body 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 released from the engaged position, in which case the cover body 300 can release the earphone 2000.

[0066] 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, i.e., manually switching the mating member 20 between the locked position and the second unlocked position along the second direction (X1 / X2); or manually switching the mating member 20 between the locked position and the second unlocked position along the second direction (X1 / X2) with the aid of a tool. For example, when a 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 from the second unlocked position to the locked position along the second direction (X1 / X2) under the action of the reset member 30. When the mating component 20 moves along the second direction (X1 / X2), the base 200 does not move along the second direction (X1 / X2) with the mating component 20. In other words, the mating component 20 can move along the second direction (X1 / X2) relative to the base 200.

[0067] The reciprocating movement of the engaging member 10 along the first direction (Z1 / Z2) between the locked position and the first unlocked position requires manual intervention, i.e., manually switching the engaging member 10 along the first direction (Z1 / Z2) between the locked position and the first unlocked position; or, manually switching the engaging member 10 along the first direction (Z1 / Z2) between the locked position and the first unlocked position with the aid of a tool. For example, when a user applies force to the engaging member 10, the engaging member 10 can move along the first direction (Z1 / Z2) from the first unlocked position to the locked position. When the user does not apply force to the engaging member 10 and the mating member 20 is in the second unlocked position, the engaging member 10 can move along the first direction (Z1 / Z2) from the locked position to the first unlocked position. When the engaging member 10 moves along the first direction (Z1 / Z2), the cover 300 moves along the first direction (Z1 / Z2) 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) may be the height direction of the charging box 1000. In other examples, as long as the first direction (Z1 / Z2) and the second direction (X1 / X2) intersect, the angle between the two may be any angle between (0°, 180°), for example, the angle between the two may be 15°, 30°, 45°, 60°, 75°, 100°, 115°, 120°, or 135°, etc. In the embodiment of the present application, only the perpendicularity of the first direction (Z1 / Z2) and the second direction (X1 / X2) is used as an example for illustration.

[0069] In the button structure 100 of the embodiment of the present application, the engaging member 10 reciprocates between the locked position and the first unlocked position along the first direction (Z1 / Z2), the engaging member 10 is connected to one of the base 200 and the cover body 300, the mating member 20 reciprocates between the locked position and the second unlocked position along the second direction (X1 / X2), the mating member 20 is connected to the other of the base 200 and the cover body 300, and 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 with each other. Therefore, compared with the charging box in the related art, the setting of the button structure 100 can prevent the relative movement between the cover body 300 and the base 200 from being unstable due to changes in the magnetic attraction force, thereby improving the stability of the charging box 1000.

[0070] The key structure 100 is further explained below with reference to the accompanying drawings.

[0071] See also Figure 3 and Figure 4 In some embodiments, the cover body 300 can be raised and lowered relative to the base 200 to switch between a clamping position and a release position. When the cover body 300 is in the clamping position, the engaging member 10 and the mating member 20 are in the locked position. When the cover body 300 is in the release position, the engaging member 10 is in the first unlocking position and the mating member 20 is in the second unlocking position. The first direction (Z1 / Z2) is the lifting direction of the cover body 300.

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

[0073] More specifically, please combine Figure 1In some embodiments, when the cover 300 is in the compressed position, it can compress the earphones 2000, thereby limiting the position of the earphones 2000 and preventing them from moving or shaking within the charging case 1000, thereby improving the stability of the earphones 2000 stored in the charging case 1000. Furthermore, the compressed position of the cover 300 can prevent the earphones 2000 from moving or shaking within the charging case 1000, which could lead to poor contact between the charging end of the earphones 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 stability of charging the earphones 2000 by the charging case 1000 and ensuring the normal function of charging and / or signal transmission. When the cover 300 is in the released position, the earphones 2000 can be placed in the charging case 1000 or removed from the charging case 1000.

[0074] Furthermore, in some embodiments, the cover 300 and the base 200 together form an earphone compartment 201 , which is used to accommodate the earphone 2000 .

[0075] 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 body 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 box 1000 increases. In this case, the earphone 2000 can be placed in the earphone compartment 201; or, the earphone 2000 can be taken out of 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 body 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 box 1000 decreases. In this case, the cover body 300 can press the charging compartment of the earphone 2000 in the earphone compartment 201, and the charging box 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 connected in sequence, and 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 placed in 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, which are sequentially connected. 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 of the earphone compartment), thereby enabling the charging case 1000 to charge and store the earphones 2000.

[0078] In certain 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, the earphone 2000 can be placed into the earphone compartment 201 through the second side 2013 of the earphone compartment along the direction from the second side 2013 of the earphone compartment to the fourth side 2017 of the earphone compartment; or, the earphone 2000 can be placed into the earphone compartment 201 through the third side 2015 of the earphone compartment along the direction from the third side 2015 of the earphone compartment to the first side 2011 of the earphone compartment.

[0079] For further information, see Figures 3 to 5 In some embodiments, the cover 300 includes a main body 310 and an extension member 330, the extension member 330 extends from the main body 310 toward the base 200, the base 200 includes a base 210 and a connecting member 230, the connecting member 230 extends from the base 210 toward the cover 300, the extension member 330 partially extends into the connecting member 230, and can be raised and lowered relative to the connecting member 230, so that the cover 300 can switch between a compressed position and a released position.

[0080] Specifically, in certain embodiments, a portion of the extension member 330 can extend into the connector 230 and can be raised and lowered relative to the connector 230. Thus, the connector 230 can guide and limit the extension member 330 during its raising and lowering, preventing the extension member 330 from getting stuck during the raising and lowering process, thereby improving the stability of the lid 300 when it is raised and lowered relative to the base 200. It will be appreciated that the projection of the extension member 330 on the base 210 is located within the connector 230, thereby ensuring that a portion of the extension member 330 can extend into the connector 230, thereby enabling the extension member 330 to be raised and lowered relative to the connector 230.

[0081] More specifically, in some embodiments, the base 210 includes a base body 211 and a top cover 213 connected to each other, and the rechargeable battery 400 and the charging circuit 500 are both disposed within the base 210. The base body 211 and the top cover 213 are detachably connected, thereby facilitating the installation of the rechargeable battery 400 and the charging circuit 500.

[0082] In some embodiments, the key structure 100 further includes an elastic member 40 connected between the base 200 and the cover 300 and extending along a first direction (Z1 / Z2). The return member 30 is connected between the mating member 20 and the base 200 and extending along a second direction (X1 / X2). When the cover 300 is in the compressed position, the elastic member 40 has a first length and the return member 30 is in a first state. When the cover 300 is in the released position, the elastic member 40 has a second length and the return member 30 is in a second state, where the second length is greater than the first length.

[0083] 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 box 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 this 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). Therefore, in the process of switching the cover 300 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 smoothly rise relative to the base 200.

[0084] In certain embodiments, the reset member 30 switches sequentially between the first state, the second state, and the first state during the process of switching the cover 300 from the compressed position to the released position. During the process of switching the cover 300 from the released position to the compressed position, the reset member 30 switches sequentially between the first state, the second state, and the first 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.

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

[0086] When the cover 300 switches from the pressed position to the released position, the reset member 30 switches sequentially between the first state, the second state, and the first state. That is, the mating member 20 switches sequentially between the locked position, the second unlocked position, and the locked position. When the mating member 20 moves from the locked position to the second unlocked position, the engagement between the mating member 20 and the engaging member 10 is released, 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 maintain the mating member 20 in the locked position.

[0087] Furthermore, in certain embodiments, when the cover body 300 is in the clamping position and the mating member 20 is subjected to the first force, the mating member 20 can move along the positive direction X1 of the second direction (X1 / X2), the reset member 30 switches from the first state to the second state, and the elastic member 40 stretches and pushes the cover body 300 to move along the upward direction of the cover body 300; when the first force disappears, the reset member 30 switches from the second state to the first state, and the mating member 20 moves along the reverse direction X2 of the second direction (X1 / X2) and is located below the locking member 10.

[0088] Specifically, in certain 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, causing the mating member 20 to move from the locked position to the second unlocked position, thereby releasing 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 negative 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.

[0089] In some embodiments, when the cover body 300 is in the release position and the cover body 300 is subjected to the second force, the elastic member 40 is compressed, the cover body 300 moves along the downward direction of the cover body 300, the locking member 10 pushes the mating member 20 to move along 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 locking member 10 is in the locking position, the mating member 20 moves along the reverse direction X2 of the second direction (X1 / X2), and the reset member 30 switches from the second state to the first state.

[0090] Specifically, in some embodiments, when the cover 300 is subjected to the 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 reset member 30 generates a reset force, and the mating member 20 moves from the locked position to the second unlocked position. When the engaging member 10 moves in the downward direction of the cover 300 to the locked position, the engaging member 10 does not generate a thrust on the mating member 20. The reset force of the reset member 30 can move the mating member 20 in the reverse direction X2 of the second direction (X1 / X2). That is, the reset force can move the mating member 20 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 compressed position.

[0091] See also Figures 3 to 5 In some embodiments, the first force acting 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 toward the inside of the base 200, and the reverse direction X2 of the second direction (X1 / X2) is toward the outside of the base 200.

[0092] Specifically, please combine Figure 4 and Figure 5 In certain 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 the engaging member 10. In this case, the reset member 30 may be a compression spring. When the reset member 30 is in a first state, the mating member 20 is in a locked position, and the reset member 30 is in a normal state (unstretched or uncompressed) or in a first compressed state. When the reset member 30 is in a second state, the mating member 20 is in a second unlocked position, and the reset member 30 is in a 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.

[0093] See also Figure 3 and Figure 7 In some embodiments, the first force acting 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 toward the outside of the base 200, and the reverse direction X2 of the second direction (X1 / X2) is toward the inside of the base 200.

[0094] Specifically, please combine Figure 7In 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 the engaging member 10. In this case, the reset member 30 may be a tension spring. When the reset member 30 is in a first state, the mating member 20 is in a locked position, and the reset member 30 is in a normal state (not stretched or compressed) or in a first stretched state. When the reset member 30 is in a second state, the mating member 20 is in a second unlocked position, and the reset member 30 is in a second stretched state. 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] See also Figures 3 to 5 , and combined with Figure 6 or Figure 7 In some embodiments, the mating piece 20 includes a mating body 21 and a hook portion 23, and the engaging piece 10 includes a engaging body 11 and a engaging portion 13. The hook portion 23 cooperates with the engaging portion 13 to enable the mating piece 20 to be engaged with the engaging piece 10.

[0096] Specifically, in some embodiments, when the engaging member 10 and the mating member 20 are both in the locked position, the hook portion 23 engages with the engaging portion 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 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 into a whole by an integral molding method, 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 from the mating body 21 when the hook portion 23 is mated with the locking portion 13, thereby ensuring the stability and reliability of the key structure 100.

[0098] In other embodiments, the mating body 21 and the hook portion 23 are separate structures, 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 connected together using a detachable connection method, which includes but is not limited to a snap connection or a bolt connection. In another example, the mating body 21 and the hook portion 23 can be connected together using a non-detachable connection method, which includes but is not limited to bonding or welding. It is 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 described in detail here.

[0099] 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 . When the cover 300 switches from the release position to the compression position, the first inclined surface 131 and the second inclined surface 231 collide with each other.

[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 hook portion 23, then when the engaging portion 13 moves along the downward direction of the cover 300 so that the engaging portion 13 and the hook portion 23 come into contact, the engaging portion 13 can only generate a thrust on the hook portion 23 along the first direction (Z1 / Z2) (i.e., the lifting and lowering direction of the charging box 1000), and this thrust cannot push the hook portion 23 to move along the second direction (X1 / X2). Therefore, 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 hook portion 23 when the first inclined surface 131 and the second inclined surface 231 come into contact, and the component of this thrust in the second direction (X1 / X2) can push the 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 first acute angle and the second acute angle may be the same or different.

[0102] In some embodiments, the engaging portion 13 is provided with a first flat surface 133, and the hook portion 23 is provided with a second flat surface 233. When the cover 300 is in the compressed position, the first flat surface 133 and the second flat surface 233 abut against each other. Both the first flat surface 133 and the second flat surface 233 are perpendicular to the first direction (Z1 / Z2). Thus, the abutment between the first flat surface 133 and the second flat surface 233 enables a snap-fit ​​engagement between the engaging portion 13 and the mating portion, thereby limiting the lifting and lowering of the cover 300 relative to the base 200.

[0103] See also Figure 4 and Figure 5In certain 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). The first guide member 600 cooperates with the elastic member 40 and is used to guide the expansion and contraction of the elastic member 40. The first guide member 600 can limit 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 on the cover 300 to switch the cover 300 from the compressed position to the released position. It should be noted that there is a one-to-one correspondence between the number of first guide members 600 and the number of elastic members 40, i.e., one first guide member 600 corresponds to one elastic member 40.

[0104] 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.

[0105] Specifically, in one example, the outer contour of the side wall of the cylinder is a continuous, uninterrupted, closed ring. Exemplarily, the cylinder may be cylindrical, in which case 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 discontinuous opening. 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, thereby reducing the friction between the elastic member 40 and the cylinder, and ensuring the stability of the elastic member 40 in the expansion and contraction along the first direction (Z1 / Z2). Exemplarily, at least one groove is provided on the cylinder, and the groove is recessed from the outer side of the side wall of the cylinder toward the center of the cylinder.

[0106] In other embodiments, the first guide member 600 is a column, and a receiving space is defined in the column, and the elastic member 40 is received in the receiving space.

[0107] Specifically, in one example, the inner contour of the sidewall of the cylinder is a continuous, uninterrupted, closed ring. For example, the accommodating space may be cylindrical, in which case the inner contour of the sidewall of the cylinder is circular. In another example, the inner contour of the sidewall of the cylinder is a non-closed ring with at least one discontinuity. Thus, when the elastic member 40 is accommodated within the accommodating space, the contact area between the elastic member 40 and the sidewall of the cylinder is small, thereby reducing friction between the elastic member 40 and the cylinder and ensuring the stability of the elastic member 40 during expansion and contraction along the first direction (Z1 / Z2).

[0108] In certain embodiments, a second guide member 700 is provided on the base 200 or the mating member 20. The second guide member 700 extends along the second direction (X1 / X2). The second guide member 700 cooperates with the reset member 30 and is used to guide the extension and retraction of the reset member 30. The second guide member 700 can limit and guide 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 restoring force on the mating member 20, thereby maintaining the mating member 20 in the locked position. It should be noted that there is a one-to-one correspondence between the number of second guide members 700 and the number of reset members 30, i.e., one second guide member 700 corresponds to one reset member 30.

[0109] 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.

[0110] Specifically, in one example, the outer contour of the sidewall of the cylinder is a continuous, uninterrupted, closed ring. For example, the cylinder may be cylindrical, in which case the outer contour of the sidewall of the cylinder is circular. In another example, the outer contour of the sidewall of the cylinder is a non-closed ring with at least one discontinuity. Thus, when the reset member 30 is sleeved onto the sidewall of the cylinder, the contact area between the reset member 30 and the sidewall of the cylinder is small, thereby reducing friction between the reset member 30 and the cylinder and ensuring the stability of the reset member 30 when extending and retracting along the second direction (X1 / X2).

[0111] In other embodiments, the second guide member 700 is a column, and a receiving space is defined in the column, and the reset member 30 is received in the receiving space.

[0112] Specifically, in one example, the inner contour of the sidewall of the cylinder is a continuous, uninterrupted, closed ring. For example, the accommodating space may be cylindrical, in which case the inner contour of the sidewall of the cylinder is circular. In another example, the inner contour of the sidewall of the cylinder is a non-closed ring with at least one discontinuity. Thus, when the elastic member 40 is accommodated within the accommodating space, the contact area between the elastic member 40 and the sidewall of the cylinder is small, thereby reducing friction between the elastic member 40 and the cylinder and ensuring the stability of the elastic member 40 during expansion and contraction along the first direction (Z1 / Z2).

[0113] Please continue reading 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 reset member 30 is connected to the blocking member 270, and the other end is connected to the matching member 20, and the matching 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 certain embodiments, the blocking member 270 is disposed on the bottom wall of the base 200 and 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. The restoring member 30 has one end connected to the blocking body 271 and the other end connected to the mating member 20. As such, when the mating member 20 moves from the locked position to the second unlocked position along the second direction (X1 / X2), the restoring member 30 generates a restoring force that restores the mating member 20 from the second unlocked position to the locked position.

[0115] Among them, along the height direction of the charging box 1000 (that is, 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 to prevent the mating member 20 from shifting during the movement. For example, the mating member 20 shifts downward 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 key structure 100.

[0116] Furthermore, in some embodiments, the mating component 20 includes a contact surface (the side of the mating component 20 opposite the support component 280) that is opposite the support component 280, and the contact area between the support component 280 and the contact surface is smaller than the area of ​​the contact surface. Thus, compared to a case where the contact area between the support component 280 and the contact surface is equal to the area of ​​the contact surface, the friction between the mating component 20 and the support component 280 is smaller, thereby facilitating movement of the mating component 20 relative to the support component 280 in the second direction (X1 / X2).

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

[0118] In certain embodiments of the present 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) with the mating member 20. The pressing member 50 is exposed from the side wall of the base 200. Thus, the user can apply the first force to the mating member 20 without reaching into the base 200. That is, the user can apply the first force to the mating member 20 through the pressing member 50, thereby ensuring normal use of the charging box 1000.

[0119] 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 formed into a whole by one-piece molding, 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.

[0120] 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 connected together using a detachable connection method, including but not limited to a snap connection or a bolt connection. In another example, the pressing member 50 and the mating member 20 can be connected together using a non-detachable connection method, including but not limited to bonding or welding.

[0121] In some embodiments, a through hole 203 is provided on the base 200, and the through hole 203 passes through the side wall of the base 200 and / or the bottom wall of the base 200. At least a portion of the mating piece 20 is located inside the base 200, and the pressing piece 50 is passed through the through hole 203 and connected to the mating piece 20.

[0122] 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 in the through hole 203 relative to the base 200 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, thereby ensuring the normal operation of the structure in the base 200 (such as the rechargeable battery 400 and the charging circuit 500, etc.).

[0123] In some embodiments, the through hole 203 passes through the side wall of the base 200, which can improve the user's convenience of use. For example, it can facilitate the user to operate the charging box 1000 with one hand.

[0124] In other embodiments, the through hole 203 passes through the bottom wall of the base 200. This can, on the one hand, reduce the possibility of external water or dust entering the base 200 through the through hole 203, prevent damage to the structure inside the base 200, and ensure the normal operation of the charging box 1000; on the other hand, it can facilitate the liquid inside the base 200 to flow out through the through hole 203, ensuring that the liquid accumulates inside the base 200 and does not cause damage to the structure inside the base 200.

[0125] In some other embodiments, the through hole 203 passes through the side wall and the bottom wall of the base 200. This can increase the size of the through hole 203, ensuring that the user can reach into the base 200 through the through hole 203 to apply the first force to the mating component 20, thereby facilitating user operation; and can also facilitate the flow of liquid inside the base 200 through the through hole 203, preventing the accumulation of liquid inside the base 200 and causing damage to the structure inside the base 200.

[0126] In some embodiments, the opposite ends of the blocking member 270 are connected to the inner side of the side wall of the base 200, and divide the base 200 into a first cavity 2051 and a second cavity 2053. The mating member 20 and the reset member 30 are both accommodated in the first cavity 2051, and the through hole 203 is connected to the first cavity 2051.

[0127] Specifically, in some embodiments, the base 200 is provided with a receiving chamber 205 for accommodating structures such as the rechargeable battery 400 and the charging circuit 500. A blocking member 270 can separate the base 200 into a first chamber 2051 and a second chamber 2053. In other words, the blocking member 270 can separate the receiving chamber 205 into the first chamber 2051 and the second chamber 2053. The fitting member 20 and the reset member 30 are both accommodated in the first chamber 2051, the through-hole 203 is in communication with the first chamber 2051, and the rechargeable battery 400 and the charging circuit 500 are both accommodated in the second chamber 2053. Therefore, if external liquid enters the receiving chamber 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 the rechargeable battery 400 and the charging circuit 500, thereby ensuring the normal operation of the charging case 1000.

[0128] In some embodiments, a limiting member 290 is provided in the base 200 , the pressing member 50 includes an extension wall 51 , and the limiting member 290 half-covers the extension wall 51 to at least limit the extension wall 51 from tilting toward the cover 300 .

[0129] Specifically, in some embodiments, the limiting member 290 is disposed in the first cavity 2051. One end of the limiting member 290 may be connected to the blocking member 270, and the other end may be connected to the side wall of the base 200. The extension wall 51 may be a side wall of the pressing member 50 in the third direction Y. 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 half-covers the extension wall 51, that is, the shape, size and contour 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 contour 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 toward the cover body 300 and causing the movement of the pressing member 50 to be offset, thereby ensuring the stability of the movement of the pressing member 50 and the mating member 20, thereby improving the stability and reliability of the key structure 100.

[0131] 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 body 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 body 300.

[0132] Specifically, in some embodiments, the first extension wall 53 and the second extension wall 55 may be two opposite side walls of the pressing member 50 in the third direction Y. Compared to the limiting member 290 including only the first limiting member 291 or the second limiting member 293, the provision of the first limiting member 291 and the second limiting member 293 can further improve the stability of the pressing member 50 moving 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 key structure 100.

[0133] 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 is in communication with the sub-cavity.

[0134] Specifically, in some embodiments, the sub-cavity is located in the first cavity 2051, and at least part of the fitting 20 is located in the sub-cavity, thereby further preventing external liquid from entering the second cavity 2053 and causing damage to structures such as the rechargeable battery 400 and the charging circuit 500 in the second cavity 2053, thereby ensuring the normal operation of the charging box 1000.
