The charging box 1000 is used to charge the earphone 2000. Among them, since the earphone system 3000 in the embodiment includes the charging box 1000, it can be understood that the earphone system 3000 at least includes the same beneficial effects as the charging box 1000, therefore, the beneficial effects of the earphone system 3000 please refer to the beneficial effects of the charging box 1000 introduced below.

[0046] In some embodiments of the present application, the earphone 2000 can be worn on the ear of the user, 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 devices, and virtual reality devices.

[0047] Specifically, in some embodiments, the earphone 2000 includes an air conduction earphone and a bone conduction earphone. Among them, the air conduction earphone, i.e. the air conduction earphone, is a kind of earphone that transmits sound through air vibration. The bone conduction earphone, i.e. the bone conduction earphone, is a kind of earphone that converts sound into different mechanical vibrations, and transmits sound waves through the human skull, bone labyrinth, inner ear lymph, spiral organ, auditory center, etc.

[0048] It is to be noted that the ear of the user includes the external auditory canal, the concha cavity, the cymba concha, the triangular fossa, the helix, the antihelix, and the tragus, etc. Among them, the concha cavity, the cymba concha, the triangular fossa, etc. have certain depth and volume in the three-dimensional space. The external auditory canal is a curved duct extending from the external auditory meatus at the deep part of the concha cavity to the eardrum.

[0049] Further, in some embodiments, the earphone 2000 includes a transducing assembly 2100 (including a first transducing assembly 2101 and a second transducing assembly 2103), which is a structure in the earphone 2000 for enabling the user to hear sound. In one example, in the case where the earphone 2000 is a bone conduction earphone 2000, the transducing assembly 2100 is configured to be located at the front side of the ear when the earphone 2000 is in the wearing state, at which time the transducing assembly 2100 does not block the external auditory canal. In another example, in the case where the earphone 2000 is an air conduction earphone 2000, the transducing assembly 2100 is configured to at least partially extend into at least one of the concha cavity, the cymba concha, the triangular fossa, etc. when the earphone 2000 is in the wearing state. It is to be noted that the following embodiments are described only by way of example with the earphone 2000 being a bone conduction earphone 2000.

[0050] Further, in some embodiments, the earphone 2000 includes a battery compartment 2200, a control compartment 2300, a first ear-hanging assembly 2400, a second ear-hanging assembly 2500, and a rear-hanging assembly 2600 disposed between the first ear-hanging assembly 2400 and the second ear-hanging assembly 2500. The first ear-hanging assembly 2400 and the second ear-hanging assembly 2500 are respectively hung on the left ear and the right ear. The battery compartment 2200 can be disposed between the first ear-hanging assembly 2400 and the rear-hanging assembly 2600, and the control compartment 2300 can be disposed between the second ear-hanging assembly 2500 and the rear-hanging assembly 2600. The first transducing assembly 2101 and the second transducing assembly 2103 are both used to convert electrical signals into mechanical vibrations to enable the user to hear sound. Among them, the first transducing assembly 2101 and the second transducing assembly 2103 are both located at the front side of the ear when the earphone 2000 is in the wearing state.

[0051] Please refer to Figure 1 and Figure 4 In some embodiments, the charging case 1000 includes a charging battery 400 and a circuit board 500, which can deliver the electrical energy of the charging battery 400 to the earphone 2000 to achieve charging of the earphone 2000 when the earphone 2000 is placed in the charging case 1000.

[0052] Further, please refer to Figure 2 and Figure 3In some embodiments, the charging case 1000 is provided with a first electrical connector 250, and the earphone 2000 is provided with an electrical connection terminal 2700. When the earphone 2000 is placed in the charging case 1000, the charging terminal 250 and the electrical connection terminal 2700 are electrically connected.

[0053] Specifically, in some embodiments, when the charging terminal 250 and the electrical connection terminal 2700 are electrically connected, the charging case 1000 and the earphone 2000 can achieve functions such as power transmission and / or data transmission. For example, when the charging terminal 250 and the electrical connection terminal 2700 are electrically connected, the circuit board 500 can transmit the power of the charging battery 400 to the battery compartment 2200 of the earphone 2000 through the charging terminal 250 and the electrical connection terminal 2700, thereby charging the earphone 2000. It should be noted that in some embodiments, the charging terminal 250 can be at least one of a spring needle and a spring sheet, etc. which can achieve electrical connection; the electrical connection terminal 2700 can be a device that can be electrically connected with the charging terminal 250.

[0054] Further, in some embodiments, the charging terminal 250 can include a plurality of charging terminals, and the electrical connection terminal 2700 can also include a plurality of electrical connection terminals. When the earphone 2000 is placed in the charging case 1000, the plurality of charging terminals 250 and the plurality of electrical connection terminals 2700 are electrically connected one by one.

[0055] Specifically, in some embodiments, a part of the plurality of charging terminals 250 is used for power transmission, and the other part is used for signal transmission; accordingly, a part of the plurality of electrical connection terminals 2700 is used for power transmission, and the other part is used for signal transmission. Among them, the plurality of charging terminals 250 are arranged side by side on the charging case 1000. In this way, compared with the non-side-by-side arrangement of the plurality of charging terminals 250 on the charging case 1000, on the one hand, it can reduce the space occupied by the charging terminal 250, make the structure more compact, and be conducive to the miniaturization of the charging case 1000; on the other hand, it can facilitate the alignment of the charging terminal 250 and the electrical connection terminal 2700, and improve the convenience of electrical connection.

[0056] Further, in some embodiments, the charging case 1000 further includes a prompt assembly 600. The prompt assembly 600 can emit an indication signal to represent different parameters of the charging case 1000. The parameters of the charging case 1000 include but are not limited to the consumed power, the remaining power, and the temperature, etc. The indication signal emitted by the prompt assembly 600 includes but is not limited to an indication light and an indication sound, etc. The present application is described by taking the indication light assembly 610 which can emit an indication light as an example. It should be noted that the prompt assembly 600 includes the indication light assembly 610, and in other embodiments of the present application, the prompt assembly 600 can be other forms of assemblies that can emit an indication signal.

[0057] Please refer toFigure 1 、 Figure 3 、 Figure 4 and Figure 5 The application provides a charging box 1000. The charging box 1000 comprises a body 100 and an indicator light assembly 610. The indicator light assembly 610 is at least partially arranged in a receiving cavity 205. The indicator light assembly 610 comprises an indicator light 611 and a light guide 613. The body 100 is provided with the receiving cavity 205. The light guide 613 covers the indicator light 611. The indicator light 611 is configured to emit an indicator light. The light guide 613 is configured to guide the indicator light out of the seat body 210.

[0058] Specifically, the indicator light assembly 610 is at least partially arranged in the receiving cavity 205. The indicator light 611 is arranged in the receiving cavity 205 and electrically connected to the circuit board 500. The indicator light 611 comprises, but is not limited to, an LED light, a laser diode or other types of light-emitting elements. In one example, the number of the indicator lights 611 in the indicator light assembly 610 can be one. In another example, the number of the indicator lights 611 in the indicator light assembly 610 can be at least two. In the embodiment in which the number of the indicator lights 611 is more than one, the types of the indicator lights 611 can be the same or different. The cross-sectional shape of the indicator light 611 can be circular, elliptical, triangular, quadrilateral or other polygonal shapes, which are not limited herein.

[0059] The light guide 613 is at least partially arranged in the seat body 210 and covers the indicator light 611. The number of the light guides 613 can be one or more, which is not limited herein. The light guide 613 can at least change the light path of the indicator light, so as to guide the indicator light out of the seat body 210. In one example, one light guide 613 covers one indicator light 611. In another example, a plurality of light guides 613 cover one indicator light 611. In yet another example, one light guide 613 covers a plurality of indicator lights 611. In addition, in other embodiments, the light guide 613 can also change the color and / or brightness of the indicator light and other parameters of the indicator light.

[0060] The light guide 613 covers the indicator light 611 and is configured to guide the indicator light out of the seat body 210, i.e., the light guide 613 can change the light path of the indicator light. The light path of the indicator light is changed at least once in the light guide 613, and the change mode comprises, but is not limited to, reflection and refraction. That is, one light guide 613 can change the light path of the indicator light multiple times.

[0061] The indicator light is ensured to be emitted to a preset area and direction, and the accuracy of the indicator signal (i.e., the indicator light) transmitted by the indicator light assembly 610 is improved.

[0062] The light guide member 613 has a guiding effect on the indicating light emitted by the indicating lamp 611. In the case that the indicating lamp 611 emits indicating light, the light guide member 613 can change the light path of the indicating light, so that the indicating light can be emitted to the outside of the charging box 1000, so that the user can accurately identify the information of the indicating light. In addition, the light guide member 613 changes the light path of the indicating light, so that the space layout inside the charging box 1000 and the placement position of the indicating lamp assembly 610 are more flexible.

[0063] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the angle between the central axis M of the indicating light emitted by the indicating lamp 611 and the central axis N of the indicating light emitted from the light guide member 613 is greater than or equal to 30° and less than or equal to 120°.

[0064] Specifically, the light guide member 613 can change the light path of the indicating light, that is, the central axis M (that is, the central axis of the light path) of the indicating light emitted by the indicating lamp 611 and the central axis N of the indicating light emitted from the light guide member 613 do not coincide and have a certain angle.

[0065] The angle between the central axis M of the indicating light emitted by the indicating lamp 611 and the central axis N of the indicating light emitted from the light guide member 613 can be 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, or 120°. If the angle between the central axis M of the indicating light emitted by the indicating lamp 611 and the central axis N of the indicating light emitted from the light guide member 613 is less than 30°, the change of the light path of the indicating light by the light guide member 613 is limited, and the indicating light is not easy to be emitted to the outside of the charging box 1000. If the angle between the central axis M of the indicating light emitted by the indicating lamp 611 and the central axis N of the indicating light emitted from the light guide member 613 is greater than 120°, the light path of the indicating light emitted from the light guide member 613 and the light path of the indicating light emitted from the indicating lamp 611 deviate too much, which is easy to mislead the user about the position of the indicating light, and is not conducive to the user to identify the information of the indicating light. In the case that the angle between the central axis M of the indicating light emitted by the indicating lamp 611 and the central axis N of the indicating light emitted from the light guide member 613 is greater than or equal to 30° and less than or equal to 120°, the light guide member 613 changes the light path of the indicating light emitted by the indicating lamp 611, and the change angle is moderate, which is conducive to the user to identify the information of the indicating light, and can also make the installation of the indicating lamp 611 flexible, so as to leave more installation space for other components.

[0066] Please refer to Figure 4 , Figure 5 and Figure 6In some embodiments, the side wall of the body 100 is provided with a through hole 215, and the light guide 613 is at least partially accommodated in the through hole 215. The indicator light assembly 610 is provided with a sealing member 615, which is sleeved on the light guide 613 and located between the inner wall of the through hole 215 and the outer wall of the light guide 613.

[0067] Specifically, the shape and size of the cross section of the light guide 613, which is cut by a plane perpendicular to the third direction (Y1 / Y2), are substantially the same as the shape and size of the cross section of the through hole 215, which is cut by a plane perpendicular to the third direction (Y1 / Y2), so as to reduce the gap between the light guide 613 and the inner wall of the through hole 215, and to reduce or even avoid the external water or dust entering the base 200 through the gap between the light guide 613 and the first through hole 215, thereby ensuring the normal operation of the structures (such as the charging battery 400 and the circuit board 500) in the base 200.

[0068] The sealing member 615 is sleeved on the light guide 613 and located between the outer side wall of the light guide 613 and the inner side wall of the through hole 215, so as to seal the gap between the outer side wall of the light guide 613 and the inner side wall of the through hole 215.

[0069] The material of the sealing member 615 includes but is not limited to metal, plastic, rubber, etc., which is not limited in the present application. The cross-sectional shape of the sealing member 615 can be circular, elliptical, triangular, quadrilateral, polygonal, etc., which is not limited herein. In one example, the number of the sealing member 615 can be one. In another example, the number of the sealing member 615 can be at least two. In the embodiment in which the number of the sealing member 615 is multiple, the cross-sectional shapes of the multiple sealing members 615 can be the same or different.

[0070] Therefore, in the case that the external fluid enters the through hole 215, the sealing member 615 can block the external fluid near the part of the through hole 215 close to the outside, so as to prevent the external fluid from entering the inside of the base 210 through the through hole 215, thereby causing damage to the structures such as the indicator light assembly 610, the charging battery 400 and the circuit board 500, and ensuring the normal operation of the charging box 1000.

[0071] Please refer to Figure 3 and Figure 4 In some embodiments, the body 100 includes the base 210 and a cover 300, and the cover 300 is connected with the base 210 and can move relative to the base 210 to change the relative position with the base 210.

[0072] Specifically, the body 100 includes a base 200 and a cover 300. The base 200 includes a seat 210 and a connecting piece 230, and the base 200 is a structure for carrying earphones 2000 in the charging box 1000. In some embodiments of the present application, the charging battery 400 and the circuit board 500 are arranged in the base 200, so that the weight of the base 200 is relatively large, and the possibility of the charging box 1000 being tilted when the earphones 2000 are stored in the charging box 1000 is reduced. The material of the base 200 includes but is not limited to plastic, aluminum alloy, copper, iron, steel, and carbon fiber composite material, etc. For example, the material of the base 200 is plastic, so that the charging box 1000 is more portable and convenient for users to carry.

[0073] The cover 300 is a structure in the charging box 1000 that can cooperate with the base 200 to limit the earphones 2000. In some embodiments of the present application, the projection of the cover 300 in the vertical direction of the height of the charging box 1000 coincides with the projection of the base 200 in the vertical direction of the height of the charging box 1000; or, the projection of the cover 300 in the vertical direction of the height of the charging box 1000 is located within the projection of the base 200 in the vertical direction of 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 material, etc. For example, the material of the cover 300 is plastic, so that the charging box 1000 is more portable 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.

[0074] The cover 300 includes a main body 310 and an extension piece 330, and the extension piece 330 extends from the main body 310 to the base 200. The base 200 includes a seat 210 and a connecting piece 230, and the connecting piece 230 extends from the seat 210 to the cover 300. The extension piece 330 partially extends into the connecting piece 230 and can move relative to the connecting piece 230. Specifically, in some examples, the extension piece 330 can be lifted relative to the connecting piece 230 along a first direction (Z1 / Z2) to change the moving distance of the cover 300 relative to the seat 210. In other examples, the extension piece 330 can also move relative to the connecting piece 230 along a second direction (X1 / X2). In still other examples, the extension piece 330 can also move relative to the connecting piece 230 along a third direction (Y1 / Y2).

[0075] Specifically, in the embodiment that the extension member 330 is lifted along the first direction (Z1 / Z2) relative to the connecting member 230, the extension member 330 can extend into the connecting member 230 and be lifted relative to the connecting member 230, so that the connecting member 230 can guide and limit the lifting of the extension member 330, preventing the extension member 330 from being stuck during lifting, thereby improving the stability of the lifting of the cover body 300 relative to the base 200. It can be understood that the projection of the extension member 330 on the seat body 210 is located in the connecting member 230, so as to ensure that the extension member 330 can extend into the connecting member 230, and thus the extension member 330 can be lifted relative to the connecting member 230.

[0076] More specifically, in some embodiments, the seat body 210 includes a seat body 211 and an upper cover 213 connected to each other, and the charging battery 400 and the circuit board 500 are arranged in the seat body 210. Among them, the seat body 211 and the upper cover 213 are detachably connected, so as to facilitate the installation of the charging battery 400 and the circuit board 500.

[0080] Specifically, the number of the light guide portions 6131, the through holes 215 and the connecting portion 6133 is not limited in the present application. The number of the through holes 215 can or can not correspond to the number of the light guide portions 6131. In the present application, the number of the through holes 215 corresponds to the number of the light guide portions 6131, which can simplify the assembly process of the light guide portions 6131, each through hole 215 corresponding to each light guide portion 6131 helps to isolate the indicator light of different light guide portions 6131, reducing light leakage and mutual interference. The first end of the light guide portion 6131 is placed in the through hole 215, which can constrain the indicator light emitted from the light guide portion 6131, further controlling the direction of the emitted indicator light and avoiding the scattering of the indicator light. The second end of each of the plurality of light guide portions 6131 is connected to the connecting portion 6133, which can make the light guide member 613 formed by the light guide portions 6131 and the connecting portion 6133 become an integral structure, facilitating the molding process, and the design of connecting the light guide portions 6131 to the connecting portion 6133 simplifies the assembly process, which only needs to connect the connecting portion 6133 to the circuit board without the need to separately connect each light guide portion 6131.

[0081] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the indicator light assembly 610 comprises a plurality of indicator lights 611, and the indicator light assembly 610 further comprises a first spacer 617. The plurality of indicator lights 611 are mounted on the circuit board 500, the first spacer 617 is mounted on the circuit board 500, the light guide member 613 is mounted on the first spacer 617, the first spacer 617 is provided with a plurality of spaced apart spacing grooves 6171, and the plurality of indicator lights 611 are respectively accommodated in different spacing grooves 6171.

[0082] Specifically, the first spacer 617 can be one or multiple, and the application takes one first spacer 617 as an example. The light guide member 613 is installed on the first spacer 617. In some embodiments, the light guide member 613 and the first spacer 617 are an integral structure, that is, the light guide member 613 and the first spacer 617 are an integral structure, thereby improving the bonding strength between the light guide member 613 and the first spacer 617, preventing the light guide member 613 and the first spacer 617 from separating during the operation of the indicator light assembly 610, and ensuring the stability and reliability of the operation of the indicator light assembly 610. In other embodiments, the light guide member 613 and the first spacer 617 are separate structures, that is, the light guide member 613 and the first spacer 617 are two different structures. In one example, the light guide member 613 and the first spacer 617 can be combined together by a detachable connection mode, which includes but is not limited to a buckle connection or a threaded connection, etc. In another example, the light guide member 613 and the first spacer 617 can be combined together by a non-detachable connection mode, which includes but is not limited to bonding or welding, etc.

[0083] The plurality of spacing grooves 6171 are spaced from each other, and the plurality of spacing grooves 6171 are not communicated in the second direction (X1 / X2) or the third direction (Y1 / Y2), thereby preventing the indicator lights 611 accommodated in different spacing grooves 6171 from interfering with each other during the emission of the indicator light from the indicator light 611 to the light guide member 613.

[0084] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the first spacer 617 is made of light-absorbing material.

[0085] Specifically, the light-absorbing material includes but is not limited to black plastic and rubber. The first spacer 617 is made of light-absorbing material, which can be that the first spacer 617 is entirely made of light-absorbing material, thereby improving the light-blocking effect and preventing the indicator lights 611 from interfering with each other; or the first spacer 617 is partially made of light-absorbing material, thereby preventing the indicator lights 611 from interfering with each other while reducing the cost.

[0086] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the inner side wall of the spacing groove 6171 is made of light-absorbing material.

[0087] Specifically, the inner side wall of the spacing groove 6171 can absorb at least part of the indication light emitted by the indicator light 611, so as to avoid part of the indication light entering the light path of other indication light and forming stray light affecting the indication signal emitted by the indicator light assembly 610, thereby further enhancing the light shielding effect of the spacing groove 6171.

[0088] Please continue to refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the inner side wall of the spacing groove 6171 is provided with a light-absorbing layer.

[0089] Specifically, the light-absorbing layer can absorb at least part of the indication light emitted by the indicator light 611, so as to avoid part of the indication light entering the light path of other indication light and forming stray light affecting the indication signal emitted by the indicator light assembly 610, thereby further enhancing the light shielding effect of the spacing groove 6171. The light-absorbing layer can be one layer or multiple layers. The light-absorbing layer is easy to disassemble and replace.

[0090] Please continue to refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the indicator light assembly 610 further comprises a second spacing piece 619, which is arranged on the first spacing piece 617 and at least between two adjacent light guide pieces 613 or light guide portions 6131.

[0091] The second spacing piece 619 arranged on the first spacing piece 617 and at least between two adjacent light guide pieces 613 / light guide portions 6131 can prevent mutual light interference of the indication light during the process of emitting from the light guide piece 613 to the outside of the seat body 210, thereby further preventing the indication light from the light guide piece 613 / light guide portion 6131 from being interfered.

[0092] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the second spacing piece 619 is made of light-absorbing material.

[0093] Specifically, the light-absorbing material includes but is not limited to black plastic and rubber. The second spacing piece 619 made of light-absorbing material can be made of light-absorbing material all over the second spacing piece 619, thereby improving the light shielding effect and preventing mutual light interference between the indicator lights 611; or the second spacing piece 619 can be made of light-absorbing material partially, thereby reducing the cost while ensuring the effect of preventing mutual light interference between the indicator lights 611.

[0094] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the outer side wall of the second spacing piece 619 is provided with a light-absorbing layer.

[0095] Specifically, the light-absorbing material includes but is not limited to black plastic and rubber. The second spacer 619 is made of light-absorbing material, which can be made of light-absorbing material throughout the second spacer 619 to improve the light-blocking effect and prevent mutual light interference between the indicator lights 611; or the second spacer 619 can be made of light-absorbing material partially, while ensuring the effect of preventing mutual light interference between the indicator lights 611, and reducing the cost.

[0096] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the indicator light has different brightness, and the different brightness represents different parameter values of the same parameter of the charging box 1000.

[0097] Specifically, the parameter of the indicator light includes the brightness of the indicator light. In the case that the movement distance represents that the cover 300 moves to the predetermined position, the state of the indicator light assembly 610 is the triggering state and the indicator light emits the indicator light, the indicator light represents different parameter values of the same parameter of the charging box 1000 through different brightness. At this time, the parameters of the charging box 1000 include but are not limited to the consumed power, the remaining power and the temperature of the charging box 1000, and the corresponding parameter values include but are not limited to the consumed power value, the remaining power value and the temperature value. The brightness and the different parameter values of the same parameter of the charging box 1000 can be positively correlated or negatively correlated.

[0098] For example, in the embodiment in which the parameter of the charging box 1000 is the remaining power, the parameter value is the remaining power value, and the brightness of the indicator light is positively correlated with the remaining power, the brightness of the indicator light includes at least a first brightness, a second brightness and a third brightness, wherein the first brightness is greater than the second brightness, and the second brightness is greater than the third brightness. The remaining power value of the charging box 1000 includes at least a first remaining power value, a second remaining power value and a third remaining power value, wherein the first remaining power value is greater than the second remaining power value, and the second remaining power value is greater than the third remaining power value. Thus, in the case that the movement distance represents that the cover 300 moves to the predetermined position, the brightness of the indicator light is the first brightness (for example, 100), which represents that the remaining power of the charging box 1000 is the first remaining power value (for example, 90%); the brightness of the indicator light is the second brightness (for example, 80), which represents that the remaining power of the charging box 1000 is the second remaining power value (for example, 80%); and the brightness of the indicator light is the third brightness (for example, 60), which represents that the remaining power of the charging box 1000 is the third remaining power value (for example, 60%). Thus, the charging box 1000 can represent different parameter values of the same parameter of the charging box 1000 through different brightness of the indicator light, so that the user can obtain different states of the charging box 1000 according to the different brightness of the indicator light.

[0099] Please refer to Figure 4 , Figure 5 and Figure 6In some embodiments, the indication light has different colors, and the different colors represent different parameter values of the same parameter of the charging case 1000.

[0100] Specifically, the parameter of the indication light includes the color of the indication light. In the case that the movement distance represents that the cover 300 moves to the predetermined position, the state of the indication light assembly 610 is the triggered state and the indication light is emitted, the indication light represents different parameter values of the same parameter of the charging case 1000 by different colors. At this time, the parameters of the charging case 1000 include, but are not limited to, the consumed power, the remaining power, and the temperature of the charging case 1000, and correspondingly, the parameter values include, but are not limited to, the consumed power value, the remaining power value, and the temperature value.

[0101] For example, in the embodiment in which the parameter of the charging case 1000 is the temperature and the parameter value is the temperature value, the color includes at least a first color (for example, red), a second color (for example, yellow), and a third color (for example, blue). The temperature value includes at least a first temperature value, a second temperature value, and a third temperature value, wherein the first temperature value is greater than the second temperature value, and the second temperature value is greater than the third temperature value. Thus, in the case that the movement distance represents that the cover 300 moves to the predetermined position, the color of the indication light is the first color, representing that the temperature of the charging case 1000 is the first temperature value (for example, 40°C); the color of the indication light is the second color, representing that the temperature of the charging case 1000 is the second temperature value (for example, 30°C); and the color of the indication light is the third color, representing that the temperature of the charging case 1000 is the third temperature value (for example, 25°C). Thus, the charging case 1000 can represent different parameter values of the same parameter of the charging case 1000 by different colors of the indication light, so that the user can obtain different states of the charging case 1000 according to the different colors of the indication light.

[0102] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the indication light has different flashing frequencies, and the different flashing frequencies represent different parameter values of the same parameter of the charging case 1000.

[0103] Specifically, the parameter of the indication light includes the flashing frequency of the indication light. In the case that the movement distance represents that the cover 300 moves to the predetermined position, the state of the indication light assembly 610 is the triggered state and the indication light is emitted, the indication light represents different parameter values of the same parameter of the charging case 1000 by different flashing frequencies. At this time, the parameters of the charging case 1000 include, but are not limited to, the consumed power, the remaining power, and the temperature of the charging case 1000, and correspondingly, the parameter values include, but are not limited to, the consumed power value, the remaining power value, and the temperature value. The flashing frequency and the different parameter values of the same parameter of the charging case 1000 can be positively correlated or negatively correlated.

[0104] For example, in the embodiment where the parameter of the charging case 1000 is the remaining power, the parameter value is the remaining power value, and the flashing frequency of the indicator light is negatively correlated with the remaining power, the flashing frequency at least includes a first flashing frequency, a second flashing frequency, and a third flashing frequency, wherein the first flashing frequency is less than the second flashing frequency, and the second flashing frequency is less than the third flashing frequency. The remaining power value at least includes a first remaining power value, a second remaining power value, and a third remaining power value, wherein the first remaining power value is greater than the second remaining power value, and the second remaining power value is greater than the third remaining power value. Thus, in the case where the movement distance represents that the cover 300 moves to the predetermined position, the flashing frequency of the indicator light is the first flashing frequency (10 MHZ), representing that the remaining power of the charging case 1000 is the first remaining power value (90%); the flashing frequency of the indicator light is the second flashing frequency (50 MHZ), representing that the remaining power of the charging case 1000 is the second remaining power value (50%); and the flashing frequency of the indicator light is the third flashing frequency (80 MHZ), representing that the remaining power of the charging case 1000 is the third remaining power value (20%). Thus, the charging case 1000 can represent different parameter values of the same parameter of the charging case 1000 by different flashing frequencies of the indicator light, so that the user can obtain different states of the charging case 1000 according to different flashing frequencies of the indicator light.

[0105] Referring to Figure 4 , Figure 5 and Figure 6 In some embodiments, the indicator light assembly 610 includes a plurality of indicator lights 611, and the indicator lights 611 are configured to emit the indicator light. Different numbers of indicator lights 611 emit the indicator light to represent different parameter values of the same parameter of the charging case 1000.

[0106] Specifically, the indicator light assembly 610 includes a plurality of indicator lights 611, and the number of the indicator lights 611 is not limited. In the case where the movement distance represents that the cover 300 moves to the predetermined position, the state of the indicator light assembly 610 is the triggered state and the indicator light assembly 610 emits the indicator light, the indicator light assembly 610 can represent different parameters of the charging case 1000 by the number of the indicator lights 611 in the triggered state and emitting the indicator light. The parameters of the charging case 1000 include but are not limited to the consumed power, the remaining power, and the temperature of the charging case 1000, and correspondingly, the parameter values include but are not limited to the consumed power value, the remaining power value, and the temperature value. The relationship between the number of the indicator lights 611 and the parameter values of the same parameter includes but is not limited to positive correlation and negative correlation.

[0107] For example, in the embodiment where the parameter of the charging case 1000 is temperature, the parameter value is a temperature value, and the number of the indicator lights 611 positively correlates with the temperature, the number of the indicator lights 611 emitting the indicator light includes at least a first number, a second number, and a third number, where the first number is greater than the second number, and the second number is greater than the third number. The temperature value includes at least a first temperature value, a second temperature value, and a third temperature value, where the first temperature value is greater than the second temperature value, and the second temperature value is greater than the third temperature value. Thus, in the case where the movement distance represents that the cover 300 moves to the predetermined position, the number of the indicator lights 611 emitting the indicator light is the first number (e.g., 4) representing that the temperature of the charging case 1000 is the first temperature value (e.g., 40°C); the number of the indicator lights 611 emitting the indicator light is the second number (e.g., 3) representing that the temperature of the charging case 1000 is the second temperature value (e.g., 30°C); and the number of the indicator lights 611 emitting the indicator light is the third number (e.g., 2) representing that the temperature of the charging case 1000 is the third temperature value (e.g., 25°C). Thus, the charging case 1000 can represent different parameter values of the same parameter of the charging case 1000 through the number of the indicator lights 611 emitting the indicator light in the indicator light assembly 610, so that the user can obtain different states of the charging case 1000 according to the number of the indicator lights 611.

[0108] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the indicator light assembly 610 includes a plurality of indicator lights 611, and the indicator lights 611 are configured to emit indicator light, and the indicator light of different indicator lights 611 is configured to represent different parameters of the charging case 1000.

[0109] Specifically, the indicator light assembly 610 includes a plurality of indicator lights 611, and the number of the indicator lights 611 is not limited. In the case that the moving distance representation cover 300 moves to a predetermined position, the state of the indicator light assembly 610 is triggered and the indicator light assembly 610 emits an indication light, different indication lights can represent different parameters of the charging case 1000. The parameters of the charging case 1000 include, but are not limited to, the consumed power, the remaining power and the temperature of the charging case 1000, and the corresponding parameter values include, but are not limited to, the consumed power value, the remaining power value and the temperature value. Wherein, when different indication lights represent the parameters of the charging case 1000, the parameters of the indication lights used can be the same or different. For example, in the case that the indicator light assembly 610 includes a first indicator light 6111, a second indicator light 6112 and a third indicator light 6113, the parameters of the charging case 1000 include a first parameter (such as the consumed power) of the charging case 1000, a second parameter (such as the remaining power) of the charging case 1000 and a third parameter (such as the temperature) of the charging case 1000, wherein the first parameter, the second parameter and the third parameter are different. In one embodiment, the indication light emitted by the first indicator light 6111 is used to represent the consumed power of the charging case 1000, the indication light emitted by the second indicator light 6112 is used to represent the remaining power of the charging case 1000, and the indication light emitted by the third indicator light 6113 is used to represent the temperature of the charging case 1000. In one example, different brightness of the indication light emitted by the first indicator light 6111 represents different consumed power values of the consumed power of the charging case 1000, different colors of the indication light emitted by the second indicator light 6112 represent different remaining power values of the remaining power of the charging case 1000, and different flashing frequencies of the indication light emitted by the third indicator light 6113 represent different temperature values of the temperature of the charging case 1000. The indicator light assembly 610 represents different parameters of the charging case 1000 through the indication light of different indicator lights 611, so that the indicator light assembly 610 can deliver at least one state of the charging case 1000, and enrich the information delivered by the indicator light assembly 610.

[0110] Please refer to Figure 4 , Figure 5 and Figure 6 Figure 4 Figure 5 Figure 6 Figure 4 Figure 5 Figure 6 Figure 4 Figure 5 Figure 6 Figure 4 Figure 5 Figure 6 Figure 4 Figure 5 Figure 6 Figure 4 Figure 5 Figure 6 Figure 4 Figure 5 Figure 6 Figure 4 Figure 5 Figure 6 Figure 4 Figure 5 Figure 6 Figure 4 Figure 5 Figure 6 Figure 4 Figure 5 Figure 6 Figure 4 Figure 5 Figure 6 Figure 4 In some embodiments, the indicator light assembly 610 includes a plurality of indicator lights 611, and the indicator lights 611 are used to emit indication lights, and the number of flashes of the indication lights of different indicator lights 611 represents different parameters.

[0111] Specifically, the indicator light assembly 610 includes a plurality of indicator lights 611, and the number of the indicator lights 611 is not limited. The number of times of flashing represents the flashing frequency. In the case that the cover 300 moves to the predetermined position, the state of the indicator light assembly 610 is triggered and the indicator light assembly 610 emits the indicator light, the indicator light emitted by different indicator lights 611 can represent different parameters of the charging case 1000 through different flashing frequencies. The parameters of the charging case 1000 include, but are not limited to, the consumed power, the remaining power and the temperature of the charging case 1000, and the parameter values include, but are not limited to, the consumed power value, the remaining power value and the temperature value.

[0112] For example, in the case that the indicator light assembly 610 includes a first indicator light 6111, a second indicator light 6112 and a third indicator light 6113, the flashing frequency of the first indicator light 6111 is a first flashing frequency, the flashing frequency of the second indicator light 6112 is a second flashing frequency, and the flashing frequency of the third indicator light 6113 is a third flashing frequency, wherein the first flashing frequency, the second flashing frequency and the third flashing frequency are different. The parameters of the charging case 1000 include a first parameter (for example, the consumed power) of the charging case 1000, a second parameter (for example, the remaining power) of the charging case 1000 and a third parameter (for example, the temperature) of the charging case 1000, wherein the first parameter, the second parameter and the third parameter are different. In one of the embodiments, the first flashing frequency represents the consumed power of the charging case 1000, the second flashing frequency represents the remaining power of the charging case 1000, and the third flashing frequency represents the temperature of the charging case 1000. The indicator light assembly 610 represents different parameters of the charging case 1000 through the number of times of flashing of the indicator light emitted by different indicator lights 611, thereby the indicator light assembly 610 can deliver at least one state of the charging case 1000, and enrich the information delivered by the indicator light assembly 610.
