In the embodiments of the present application, the earphone system 3000 includes the charging box 1000, and 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 are described below in the beneficial effects of the charging box 1000.

[0055] In some embodiments of the present application, the earphone 2000 can be worn on the ear of a user and can be used in cooperation with a mobile phone, a computer, a smart wearable device (such as a smart watch, a smart bracelet, smart glasses, a smart helmet, etc.), a head-mounted device, a virtual reality device, and the like.

[0056] Specifically, in some embodiments, the earphone 2000 includes an air conduction earphone and a bone conduction earphone. The air conduction earphone is an earphone that transmits sound through air vibration. The bone conduction earphone is an earphone that converts sound into different mechanical vibrations and transmits sound waves through the human skull, bone labyrinth, inner ear lymph, cochlea, auditory center, and the like.

[0057] It should be noted that the ear of a user includes an external auditory canal, a concha cavity, a cymba concha, a triangular fossa, a helix, a tragus, and the like. The concha cavity, the cymba concha, the triangular fossa, and the like have a certain depth and volume in three-dimensional space.

[0058] Further, in some embodiments, the earphone 2000 includes a transduction assembly 2100 (including a first transduction assembly 2101 and a second transduction assembly 2103), which is a structure in the earphone 2000 for enabling a user to hear sound. In one example, in the case where the earphone 2000 is a bone conduction earphone 2000, the transduction assembly 2100 is configured to be located on the front side of the ear when the earphone 2000 is in a wearing state, at which time the transduction 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 transduction assembly 2100 is configured to at least partially extend into at least one of the concha cavity, the cymba concha, the triangular fossa, and the like when the earphone 2000 is in a wearing state. It should be noted that the embodiments described below are described only by way of example with the earphone 2000 being a bone conduction earphone 2000.

[0059] Further, in some embodiments, the earphone 2000 includes a battery compartment 2200, a control compartment 2300, a first ear hook assembly 2400, a second ear hook assembly 2500, and a rear hook assembly 2600 disposed between the first ear hook assembly 2400 and the second ear hook assembly 2500. The first ear hook assembly 2400 and the second ear hook assembly 2500 are respectively hung on the left ear and the right ear. The battery compartment 2200 can be disposed between the first ear hook assembly 2400 and the rear hook assembly 2600, and the control compartment 2300 can be disposed between the second ear hook assembly 2500 and the rear hook assembly 2600. The first transduction assembly 2101 and the second transduction assembly 2103 are both used to convert electrical signals into mechanical vibrations to enable a user to hear sound. In the case where the earphone 2000 is in a wearing state, the first transduction assembly 2101 and the second transduction assembly 2103 are both located on the front side of the ear.

[0060] Please see Figure 1 and Figure 4 In some embodiments, the charging case 1000 includes a rechargeable battery 400 and a circuit board 500. When the earphone 2000 is placed in the charging case 1000, the circuit board 500 can transfer electrical energy from the rechargeable battery 400 to the earphone 2000 to charge the earphone 2000.

[0061] Furthermore, please combine Figure 2 and Figure 3 In some embodiments, the charging case 1000 is provided with a first electrical connector 250, and the earphone 2000 is provided with a power terminal 2700. When the earphone 2000 is placed in the charging case 1000, the charging terminal 250 and the power terminal 2700 are electrically connected.

[0062] Specifically, in some embodiments, when the charging terminal 250 and the power receiving terminal 2700 are electrically connected, functions such as power transfer and / or data transfer can be realized between the charging case 1000 and the earphone 2000. For example, when the charging terminal 250 and the power receiving terminal 2700 are electrically connected, the circuit board 500 can transfer the electrical energy of the rechargeable battery 400 to the battery compartment 2200 of the earphone 2000 through the charging terminal 250 and the power receiving 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 the devices that can realize electrical connection, such as a spring pin and a spring contact; the power receiving terminal 2700 can be a device that can be electrically connected to the charging terminal 250.

[0063] Furthermore, in some embodiments, the charging terminal 250 may include multiple terminals, and the power connection terminal 2700 may also include multiple terminals. When the earphone 2000 is placed in the charging case 1000, the multiple charging terminals 250 and the multiple power connection terminals 2700 are electrically connected one-to-one.

[0064] Specifically, in some embodiments, a portion of the plurality of charging terminals 250 is used for power transmission, and another portion is used for signal transmission; correspondingly, a portion of the plurality of power receiving terminals 2700 is used for power transmission, and another portion is used for signal transmission. The plurality of charging terminals 250 are arranged side-by-side on the charging box 1000. This arrangement, compared to a non-side-by-side arrangement, reduces the space occupied by the charging terminals 250, making the structure more compact and facilitating the miniaturization of the charging box 1000. Furthermore, it facilitates the alignment of the charging terminals 250 and the power receiving terminals 2700, improving the convenience of electrical connection.

[0065] Please see Figure 1 , Figure 3 ,Figure 4 and Figure 5 The embodiments of the present application provide a charging box 1000. The charging box 1000 comprises a base 210, a cover 300, a position detection assembly 100 and a prompt assembly 600. 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. The position detection assembly 100 is arranged on the cover 300 and the base 210 and is used to detect the moving distance of the cover 300 relative to the base 210. The prompt assembly 600 changes the state based on the moving distance detected by the position detection assembly 100, and the state of the prompt assembly 600 at least comprises a triggered state.

[0066] Specifically, the charging box 1000 comprises a base 200 and a cover 300. The base 200 comprises a base body 210 and a connecting piece 230, and the base 200 is a structure used to carry 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 falling when the earphones 2000 are stored in the charging box 1000 is reduced. The material of the base 200 comprises but is not limited to plastic, aluminum alloy, copper, iron, steel and carbon fiber composite material, etc. Exemplarily, the material of the base 200 is plastic, so that the charging box 1000 is more portable and convenient for users to carry.

[0067] The cover 300 is a structure that can cooperate with the base 200 to limit the earphones 2000 in the charging box 1000. 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 in the projection of the base 200 in the vertical direction of the height of the charging box 1000. The material of the cover 300 comprises but is not limited to plastic, aluminum alloy, copper, iron, steel and carbon fiber composite material, etc. Exemplarily, 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 can be the same as or different from the material of the base 200.

[0068] The cover body 300 comprises a main body 310 and an extension member 330 extending from the main body 310 towards the base 200, the base 200 comprises a base body 210 and a connecting member 230 extending from the base body 210 towards the cover body 300, the extension member 330 partially extends into the connecting member 230 and is movable relative to the connecting member 230. Specifically, in some examples, the extension member 330 is movable relative to the connecting member 230 along a first direction (Z1 / Z2) to change the moving distance of the cover body 300 relative to the base body 210. In other examples, the extension member 330 is further movable relative to the connecting member 230 along a second direction (X1 / X2). In yet other examples, the extension member 330 is further movable relative to the connecting member 230 along a third direction (Y1 / Y2).

[0069] Specifically, in the embodiment where the extension member 330 is movable relative to the connecting member 230 along the first direction (Z1 / Z2), a portion of the extension member 330 is capable of extending into the connecting member 230 and is movable relative to the connecting member 230, thus the connecting member 230 is capable of guiding and limiting the movement of the extension member 330, preventing the extension member 330 from being stuck during the movement, thus the stability of the cover body 300 relative to the base 200 is improved. It is understood that the projection of the extension member 330 on the base body 210 is located within the connecting member 230, thus the portion of the extension member 330 is capable of extending into the connecting member 230, and the extension member 330 is movable relative to the connecting member 230.

[0070] More specifically, in some examples, the base body 210 comprises a base body 211 and an upper cover 213 connected to each other, the charging battery 400 and the circuit board 500 are arranged in the base body 210. The base body 211 and the upper cover 213 are detachably connected, thus the installation of the charging battery 400 and the circuit board 500 is facilitated.

[0071] The position detection assembly 100 is a structure for detecting the moving distance of the cover body 300 relative to the base body 210. The position detection assembly 100 is arranged in the cover body 300 and the base body 210, that is, the position detection assembly 100 detects the moving distance of the cover body 300 relative to the base body 210 through the cooperation between the first detection member (for example, the magnetic member 30) arranged in the cover body 300 and the second detection member (for example, the Hall sensor 10) arranged in the base body 210.

[0072] The movement distance of the cover 300 relative to the base 210 includes at least one movement distance in the first direction (Z1 / Z2), the second direction (X1 / X2), and the third direction (Y1 / Y2). The position detection assembly 100 detects the movement distance in a manner including but not limited to detecting magnetic flux, detecting pressure, and detecting infrared light, etc. The number of the first detection member and the second detection member can be one or more, which is not limited in the application. The cross-sectional shape of the first detection member and the second detection member can be circular, elliptical, triangular, quadrilateral, or other polygonal shapes, etc., which is not limited herein. In one example, the number of the first detection member and the second detection member is the same, and in another example, the number of the first detection member and the second detection member is different.

[0073] The prompt assembly 600 changes the state of the prompt assembly 600 based on the movement distance detected by the position detection assembly 100. That is, the state of the prompt assembly 600 can be different when the movement distance of the cover 300 relative to the base 210 is different. The state of the prompt assembly 600 includes at least the trigger state of the prompt assembly 600, in which the prompt assembly 600 can emit an indication signal to represent different parameters of the charging case 1000, including but not limited to the amount of power consumed, the amount of power remaining, and the temperature, etc.

[0074] The prompt assembly 600 includes at least one prompt member, which changes the state of the prompt member based on the movement distance detected by the position detection assembly 100. The indication signal emitted by the prompt member includes but is not limited to indication light and indication sound, etc. In one example, the number of the prompt member in the prompt assembly 600 can be one. In another example, the number of the prompt member in the prompt assembly 600 is at least two. In the embodiment in which the number of the prompt member is multiple, the indication signals emitted by the multiple prompt members can be the same or different. The cross-sectional shape of the prompt member can be circular, elliptical, triangular, quadrilateral, or other polygonal shapes, etc., which is not limited herein.

[0075] The cover 300 of the charging case 1000 can move relative to the base 210 to change the relative position with the base 210 to open and close the charging case 1000, thereby charging the charging object (such as the earphone 2000) in the earphone system 10000. Further, the charging case 1000 detects the movement distance of the cover 300 relative to the base 210 by using the position detection assembly 100 arranged on the cover 300 and the base 210, and the prompt assembly 600 changes the state of the prompt assembly 600 based on the detected movement distance to represent different parameters of the charging case 1000, so that the user can intuitively obtain the state of the charging case 1000 corresponding to the parameters of the charging case 1000, thereby realizing real-time monitoring of the charging case 1000.

[0076] Please refer to Figure 4 andFigure 5 In some embodiments, the position detection assembly 100 includes the Hall sensor 10 and the magnetic piece 30, the magnetic piece 30 is arranged in the cover 300 and moves with the cover 300, the Hall sensor 10 is arranged in the base 210, the Hall sensor 10 cooperates with the magnetic piece 30, and the Hall sensor 10 detects the moving distance of the cover 300 relative to the base 210 through the change of the magnetic flux.

[0077] Specifically, in the present application, the position detection assembly 100 detects the moving distance of the cover 300 relative to the base 210 through the change of the magnetic flux. The change of the magnetic flux representing the moving distance of the cover 300 relative to the base 210 can be represented by a group of Hall sensors 10 and magnetic pieces 30, or a plurality of groups of Hall sensors 10 and magnetic pieces 30 in a certain combination. The Hall sensor 10 can be S-pole triggered (when the S-pole of the magnetic piece 30 is close to the Hall sensor 10, the Hall sensor 10 can detect the change and respond accordingly), or N-pole triggered (when the N-pole of the magnetic piece 30 is close to the Hall sensor 10, the Hall sensor 10 can detect the change and respond accordingly), and the triggering mode of the Hall sensor 10 is not limited in the present application.

[0078] In one example, the magnetic piece 30 is arranged in the cover 300, and the Hall sensor 10 is arranged in the base 210. The Hall sensor 10 arranged in the base 210 senses the change of the magnetic flux of the magnetic piece 30 arranged in the cover 300 to detect the moving distance of the cover 300 relative to the base 210. In another example, the Hall sensor 10 is arranged in the cover 300, and the magnetic piece 30 is arranged in the base 210. The Hall sensor 10 arranged in the cover 300 senses the change of the magnetic flux of the magnetic piece 30 arranged in the base 210 to detect the moving distance of the cover 300 relative to the base 210. In still another example, the cover 300 is provided with the magnetic piece 30 and the Hall sensor 10, and the base 210 is also provided with the magnetic piece 30 and the Hall sensor 10. The Hall sensor 10 arranged in the base 210 senses the change of the magnetic flux of the magnetic piece 30 arranged in the cover 300, and the Hall sensor 10 arranged in the cover 300 senses the change of the magnetic flux of the magnetic piece 30 arranged in the base 210. The Hall sensor 10 has a small volume and is easy to integrate into the charging case 1000, and the power consumption of the Hall sensor 10 is low, which is suitable for portable devices such as the charging case 1000, and helps to prolong the endurance time of the charging case 1000.

[0079] Please refer to Figure 4 and Figure 5In some embodiments, the state of the prompting assembly 600 is in a dormant state when the moving distance represents that the cover 300 is in the pressing position, and the state of the prompting assembly 600 is in a triggered state when the moving distance represents that the cover 300 moves to the predetermined position, and an indication signal is sent to indicate the parameter of the charging case 1000. The pressing position is a position of the cover 300 when the cover 300 is pressed to place the earphone 2000 to be charged on the seat 210.

[0080] Specifically, the movable connection refers to a connection between two or more components, which allows relative movement between the connected components. The cover 300 is movably connected with the seat 210 and can move relative to the seat 210 to change the relative position with the seat 210, so that the cover 300 can switch between the pressing position and the releasing position when the cover 300 moves relative to the seat 210. 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 case 1000; when the cover 300 is in the releasing position, the cover 300 can release the earphone 2000, and at this time, the earphone 2000 can be taken out of the charging case 1000.

[0081] The predetermined position includes the releasing position and any position between the pressing position and the releasing position. The pressing position can be a limit position to which the cover 300 can move downward relative to the seat 210 (i.e., the cover 300 moves relative to the seat 210 in the direction from the cover 300 to the seat 210) along the lifting direction of the cover 300 (i.e., the first direction (Z1 / Z2), i.e., the height direction of the charging case 1000); the releasing position can be a position to which the cover 300 can move upward relative to the seat 210 (i.e., the cover 300 moves relative to the seat 210 in the direction from the seat 210 to the cover 300) along the lifting direction of the cover 300 when the cover 300 has the maximum moving distance.

[0082] More specifically, when the cover 300 is in the pressing position, the cover 300 can press the earphone 2000 (i.e., the earphone to be charged), so that the earphone 2000 can be limited, the movement or shaking of the earphone 2000 in the charging case 1000 can be prevented, and the stability of the earphone 2000 stored in the charging case 1000 can be improved. At the same time, when the cover 300 is in the pressing position, the movement or shaking of the earphone 2000 in the charging case 1000 can also be prevented, so that the poor contact between the charging end (i.e., the charging terminal) of the earphone 2000 and the charging end (i.e., the charging terminal 250) of the charging case 1000 can be prevented, the stability of the charging of the earphone 2000 by the charging case 1000 can be improved, and the normal implementation of the charging function and / or the signal transmission function can be ensured. When the cover 300 is in the releasing position, the earphone 2000 can be put into the charging case 1000, or the earphone 2000 can be taken out of the charging case 1000.

[0083] More specifically, in the case that the cover 300 is in the pressed position, the state of the prompting assembly 600 is the dormant state, which can be used to indicate that the cover 300 is in the pressed position; in the case that the cover 300 is in the predetermined position, the state of the prompting assembly 600 is the triggered state, and the indication signal is emitted to indicate the parameter of the charging case 1000. That is, in the triggered state, the prompting assembly 600 can emit the indication signal to indicate the parameter of the charging case 1000 through the indication signal, thereby indicating the state of the charging case 1000.

[0084] The predetermined position can be the released position, or any position between the released position and the pressed position (excluding the pressed position), and the timing at which the indication light assembly 610 emits the indication signal can be set more flexibly.

[0085] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the prompting assembly 600 is an indication light assembly 610, and the state of the prompting assembly 600 includes the dormant state and the triggered state. The indication signal includes an indication light, and in the case that the moving distance represents that the cover 300 is in the pressed position, the state of the indication light assembly 610 is the dormant state, and in the case that the moving 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 to indicate the parameter of the charging case 1000.

[0086] The indication light assembly 610 includes at least one prompting element, which changes the state of the prompting element based on the moving distance detected by the position detection assembly 100. In an embodiment, the indication signal emitted by the prompting element is an indication light, and the prompting element includes but is not limited to an LED light, a laser diode, or other types of light-emitting elements. In one example, the number of prompting elements in the prompting assembly 600 can be one. In another example, the number of prompting elements in the prompting assembly 600 can be at least two. In the embodiment in which the number of prompting elements is multiple, the types of the multiple prompting elements can be the same or different. The cross-sectional shape of the prompting element can be circular, elliptical, triangular, quadrilateral, or other polygonal shapes, which are not limited herein.

[0087] In the case that the moving distance represents that the cover 300 is in the pressed position, the state of the indicator light assembly 610 is a dormant state. In the dormant state, the indicator light assembly 610 does not emit the indicator light, i.e., the indicator light assembly 610 is off. In the case that the cover 300 is switched from the pressed position to the predetermined position, the indicator light assembly 610 is switched from the dormant state to a triggered state and emits the indicator light, i.e., the indicator light assembly 610 is on. In the triggered state, the parameters of the indicator light emitted by the indicator light assembly 610 include but are not limited to the brightness, color and flickering frequency of the indicator light, etc. These parameters of the indicator light can reflect the parameters of the charging case 1000.

[0088] Referring 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 case 1000.

[0089] Specifically, the parameters of the indicator light include the brightness of the indicator light. In the case that the moving 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 is emitted, the indicator light represents different parameter values of the same parameter of the charging case 1000 by different brightness. At this time, the parameters of the charging case 1000 include but are not limited to the consumed power, remaining power and temperature of the charging case 1000, and correspondingly, the parameter values include but are not limited to the consumed power value, remaining power value and temperature value. The brightness and the different parameter values of the same parameter of the charging case 1000 can be positively correlated or negatively correlated.

[0090] 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 brightness of the indication light positively correlates with the remaining power, the brightness of the indication light at least includes a first brightness, a second brightness, and a third brightness, where 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 case 1000 at least includes a first remaining power value, a second remaining power value, and a third remaining power value, where 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 brightness of the indication light is the first brightness (e.g., 100), representing that the remaining power of the charging case 1000 is the first remaining power value (e.g., 90%); the brightness of the indication light is the second brightness (e.g., 80), representing that the remaining power of the charging case 1000 is the second remaining power value (e.g., 80%); and the brightness of the indication light is the third brightness (e.g., 60), representing that the remaining power of the charging case 1000 is the third remaining power value (e.g., 60%). Thus, the charging case 1000 can represent different parameter values of the same parameter of the charging case 1000 by different brightness of the indication light, so that the user can obtain different states of the charging case 1000 according to different brightness of the indication light.

[0091] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the indication light has different colors, and different colors represent different parameter values of the same parameter of the charging case 1000.

[0092] Specifically, the parameter of the indication light includes the color of the indication light. In the case where 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 parameter of the charging case 1000 includes but is not limited to the consumed power of the charging case 1000, the remaining power, and the temperature, and correspondingly, the parameter value includes but is not limited to the consumed power value, the remaining power value, and the temperature value.

[0093] For example, in an embodiment where the parameter of the charging case 1000 is temperature and the parameter value is a temperature value, the color includes at least a first color (e.g., red), a second color (e.g., yellow), and a third color (e.g., blue). 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 color of the indication light is the first color, representing that the temperature of the charging case 1000 is the first temperature value (e.g., 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 (e.g., 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 (e.g., 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 different colors of the indication light.

[0094] Referring 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.

[0095] Specifically, the parameter of the indication light includes the flashing frequency of the indication light. In the case where 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 emits the indication light, the indication light represents different parameter values of the same parameter of the charging case 1000 by different flashing frequencies. At this time, the parameter of the charging case 1000 includes, but is not limited to, the consumed power of the charging case 1000, the remaining power, and the temperature, and the parameter value includes, but is 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] The indicator light assembly 610 represents different parameters of the charging case 1000 by the indication lights 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.

[0103] 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 used to emit indication lights, and the number of flashes of the indication lights of different indicator lights 611 represents different parameters.

[0104] Specifically, the indicator light assembly 610 comprises a plurality of indicator lights 611, the number of the indicator lights 611 is not limited, and the number of the flashes represents the flash frequency. When the moving distance represents that the cover 300 moves to a predetermined position, the indicator light assembly 610 is in a triggered state and emits an indication light, the indication light emitted by different indicator lights 611 can represent different parameters of the charging case 1000 through different flash 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.

[0105] For example, when the indicator light assembly 610 comprises a first indicator light 6111, a second indicator light 6112 and a third indicator light 6113, the flash frequency of the first indicator light 6111 is a first flash frequency, the flash frequency of the second indicator light 6112 is a second flash frequency, and the flash frequency of the third indicator light 6113 is a third flash frequency, wherein the first flash frequency, the second flash frequency and the third flash frequency are different. 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 first flash frequency represents the consumed power of the charging case 1000, the second flash frequency represents the remaining power of the charging case 1000, and the third flash 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 flashes of the indication 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.

[0106] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the indicator light assembly 610 comprises the indicator light 611 and the light guide 613. The light guide 613 covers the indicator light 611, the indicator light 611 is used to emit an indication light, and the light guide 613 is used to guide the indication light out of the seat body 210.

[0107] Specifically, the indicator light 611 is arranged in the seat body 210 and is electrically connected with the circuit board 500. The indicator light 611 includes, 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 light 611 in the indicator light assembly 610 can be one. In another example, the number of the indicator light 611 in the indicator light assembly 610 can be at least two. In the embodiment in which the number of the indicator light 611 is multiple, the types of the multiple 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.

[0108] 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 guide 613 can be one or multiple, which is not limited in the present application. The light guide 613 can at least change the light path of the indicator light, so that the indicator light can be guided out of the seat body 210. In one example, one light guide 613 covers one indicator light 611. In another example, multiple light guides 613 cover one indicator light 611. In yet another example, one light guide 613 covers multiple 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.

[0109] The light guide 613 covers the indicator light 611, so that the light guide 613 guides the indicator light out of the seat body 210. Thus, the light guide 613 can control the propagation direction of the indicator light, ensure that the indicator light is emitted to a predetermined area and direction, and improve the accuracy of the indicator signal (i.e., the indicator light) transmitted by the indicator light assembly 610.

[0110] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the central axis M of the indicator light emitted by the indicator light 611 and the central axis N of the indicator light emitted from the light guide 613 have an included angle.

[0111] Specifically, the light guide 613 can change the light path of the indicator light, i.e., the central axis M (i.e., the central axis of the light path) of the indicator light emitted by the indicator light 611 and the central axis N of the indicator light emitted from the light guide 613 do not coincide and have a certain included angle. The light guide 613 changes the transmission path of the indicator light emitted by the indicator light 611, making the installation of the indicator light 611 flexible and leaving more installation space for other components. In the present embodiment, the included angle between the central axis M and the central axis N is 90 degrees. In other embodiments, the included angle between the central axis M and the central axis N can also be 45 degrees, 60 degrees, or 75 degrees, etc.

[0112] Please refer to Figure 4 , Figure 5 andFigure 6 In some embodiments, the side wall of the base 210 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.

[0113] 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 that the gap between the light guide 613 and the inner wall of the through hole 215 can be reduced, and the water or dust from the outside can be prevented from entering the base 200 through the gap between the light guide 613 and the first through hole 215, so that the normal work of the structures (such as the charging battery 400 and the circuit board 500) in the base 200 can be ensured.

[0114] 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.

[0115] 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 or other polygonal shape, 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.

[0116] 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 and causing damage to the structures such as the indicator light assembly 610, the charging battery 400 and the circuit board 500, so that the normal work of the charging box 1000 can be ensured.

[0117] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the indicator light assembly 610 includes multiple indicator lights 611, and the indicator light assembly 610 includes multiple light guides 613, which are arranged in sequence and spaced apart along the moving direction perpendicular to the movement of the cover 300 relative to the base 210, and the indicator light 611 and the light guide 613 are respectively arranged in correspondence in the moving direction.

[0118] Specifically, in the embodiment in which the indicator light assembly 610 comprises a plurality of indicator lights 611 and a plurality of light guides 613, the plurality of light guides 613 are arranged in sequence and at intervals along a movement direction perpendicular to the movement of the cover body 300 relative to the seat body 210, i.e., the plurality of light guides 613 are arranged in sequence and at intervals along a movement direction perpendicular to the first direction (Z1 / Z2). The light guides 613 arranged at intervals are neat and easy to identify, which can improve the readability of the indicator signals emitted by the indicator light assembly 610 and provide a good visual effect. The indicator lights 611 and the light guides 613 are respectively arranged in correspondence in the movement direction, which can ensure that the indicator lights 611 are uniformly guided by the light guides 613. Each indicator light 611 cooperates with the corresponding light guide 613 to ensure that the indicator light propagates in a specific direction and reduces scattering and waste of the indicator light.

[0119] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the side wall of the seat body 210 is provided with a through hole 215, the indicator light assembly 610 comprises a plurality of indicator lights 611, the light guide 613 comprises a plurality of light guide portions 6131 and a connecting portion 6133, and the plurality of light guide portions 6131 are arranged in sequence and at intervals along a movement direction perpendicular to the movement of the cover body 300 relative to the seat body 210. The first end of the light guide portion 6131 is contained in the through hole 215, the second end of each of the plurality of light guide portions 6131 is connected to the connecting portion 6133, and the plurality of indicator lights 611 and the plurality of light guide portions 6131 are respectively arranged in correspondence in the movement direction.

[0120] 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 correspond to or 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 light guide portion 6131 corresponds to a through hole 215, which helps to isolate the indicator light of different light guide portions 6131 and reduce cross talk 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 control the direction of the emitted indicator light, and avoid 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 portion 6131 and the connecting portion 6133 form a whole structure, facilitate processing and molding, and simplify the assembly process by connecting the connecting portion 6133 to the circuit board without separately connecting each light guide portion 6131.

[0121] Please refer to Figure 4 , Figure 5 and Figure 6In some embodiments, the indicator light assembly 610 includes a plurality of indicator lights 611, and the indicator light assembly 610 further includes a first spacer 617. The plurality of indicator lights 611 are mounted on the circuit board 500, and the first spacer 617 is mounted on the circuit board 500. The light guide 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.

[0122] Specifically, the first spacer 617 can be one or a plurality of. The first spacer 617 is one in the present application. The light guide 613 is mounted on the first spacer 617. In some embodiments, the light guide 613 and the first spacer 617 are an integral structure, i.e., the light guide 613 and the first spacer 617 are an integral structure. Thus, the combination strength between the light guide 613 and the first spacer 617 can be improved, and the light guide 613 and the first spacer 617 are prevented from being separated during the operation of the indicator light assembly 610, thereby ensuring the stability and reliability of the operation of the indicator light assembly 610. In other embodiments, the light guide 613 and the first spacer 617 are a split structure, i.e., the light guide 613 and the first spacer 617 are two different structures. In one example, the light guide 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 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.

[0123] The plurality of spacing grooves 6171 are spaced apart 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). Thus, the indicator lights 611 accommodated in different spacing grooves 6171 emit indicator lights without interfering with each other, and the spacing grooves 6171 can prevent the indicator lights from being mutually light-strung during the process of the indicator lights emitted from the indicator lights 611 to the light guide 613.

[0124] Please refer to Figure 4 , Figure 5 and Figure 6 In some embodiments, the first spacer 617 is made of light-absorbing material.

[0125] 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 being mutually light-strung. Alternatively, the first spacer 617 can be partially made of light-absorbing material, which can prevent the indicator lights 611 from being mutually light-strung while reducing the cost.

[0126] Please see Figure 4 , Figure 5 and Figure 6 In some embodiments, the inner wall of the spacer 6171 is made of a light-absorbing material.

[0127] Specifically, the inner wall of the spacer slot 6171 can absorb at least part of the indicator light emitted by the indicator light 611, preventing some of the indicator light from entering the optical path of other indicator lights and forming stray light that affects the indicator light assembly 610 from emitting indicator signals, so as to further enhance the light blocking effect of the spacer slot 6171.

[0128] Please see Figure 4 , Figure 5 and Figure 6 In some embodiments, the inner wall of the spacer 6171 is provided with a light-absorbing layer.

[0129] Specifically, the light-absorbing layer can absorb at least a portion of the indicator light emitted by the indicator light 611, preventing some indicator light from entering the optical path of other indicator lights and forming stray light that affects the indicator signal emitted by the indicator light assembly 610, thereby further enhancing the light-blocking effect of the spacer slot 6171. The light-absorbing layer can be a single layer or multiple layers. In an embodiment where the light-absorbing layer is multi-layered, the structures of different layers can have different characteristics to absorb indicator light of different wavelengths. The light-absorbing layer is easy to install and remove, and convenient to replace.

[0130] Please see Figure 4 , Figure 5 and Figure 4 In some embodiments, the indicator light assembly 610 further includes a second spacer 619 disposed on the first spacer 617 and located at least between two adjacent light guides 613 or light guide portions 6131.

[0131] The second spacer 619 is disposed on the first spacer 617 and is located at least between two adjacent light guides 613 / light guide portions 6131. ​​It can prevent the indicator light from crossing each other during the process of the indicator light being emitted from the light guide 613 to the outside of the base 210, thereby further preventing the indicator light exposed from the light guide 613 / light guide portion 6131 from crossing.

[0132] Please see Figure 5 , Figure 4 and Figure 5 In some embodiments, the second spacer 619 is made of a light-absorbing material.

[0133] 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 entirely, so as to improve the light isolation effect and prevent the light from being mixed between the indicator lights 611; or can be made of light-absorbing material partially, so as to reduce the cost while ensuring the effect of preventing the light from being mixed between the indicator lights 611.

[0134] Referring to Figure 4 , Figure 5 and Figure 4 , in some embodiments, the outer side wall of the second spacer 619 is provided with a light-absorbing layer.

[0135] 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 entirely, so as to improve the light isolation effect and prevent the light from being mixed between the indicator lights 611; or can be made of light-absorbing material partially, so as to reduce the cost while ensuring the effect of preventing the light from being mixed between the indicator lights 611.

[0136] Referring to Figure 5 and Figure 4 , in some embodiments, the prompting assembly 600 is a responding assembly 630, and the state of the prompting assembly 600 includes a dormant state and a triggered state. The indication signal includes an indication sound. When the moving distance represents that the cover 300 is in a compressed position, the state of the responding assembly 630 is the dormant state. When the moving distance represents that the cover 300 moves to a predetermined position, the state of the responding assembly 630 is the triggered state, and the indication sound is emitted to indicate the parameter of the charging case 1000. The compressed position is the position of the cover 300 when the cover 300 is compressed and placed on the seat 210.

[0137] The responding assembly 630 includes at least one prompting element, which changes the state of the prompting element based on the moving distance detected by the position detection assembly 100. In an embodiment, the indication signal emitted by the prompting element is an indication sound, and the prompting element includes, but is not limited to, a buzzer 631, a speaker, a voice chip or other types of sound-emitting elements. In one example, the number of prompting elements in the responding assembly 630 can be one. In another example, the number of prompting elements in the responding assembly 630 can be at least two. In the embodiment in which the number of prompting elements is multiple, the types of the multiple prompting elements can be the same or different. The cross-sectional shape of the prompting element can be circular, elliptical, triangular, quadrilateral or other polygonal shapes, which are not limited herein.

[0138] In the case that the moving distance represents that the cover 300 is in the pressed position, the state of the response component 630 is a dormant state. In the dormant state, the response component 630 does not emit the indication sound. In the case that the cover 300 is switched from the pressed position to the predetermined position, the response component 630 is switched from the dormant state to a triggered state and emits the indication sound. In the triggered state, the parameters of the indication sound emitted by the response component 630 include but are not limited to the duration, decibel and frequency of the indication sound, etc. These parameters of the indication sound can reflect the parameters of the charging case 1000.

[0139] Please refer to Figure 5 and Figure 4 In some embodiments, the indication sound has different durations, and the different durations represent different parameter values of the same parameter of the charging case 1000.

[0140] Specifically, the parameters of the indication sound include the duration of the indication sound. In the case that the moving distance represents that the cover 300 moves to the predetermined position, the state of the response component 630 is the triggered state and the response component 630 emits the indication sound, the indication sound represents different parameter values of the same parameter of the charging case 1000 by different durations. 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 the corresponding parameter values include but are not limited to the consumed power value, the remaining power value and the temperature value. The duration and the different parameter values of the same parameter of the charging case 1000 can be positively correlated or negatively correlated. Thus, the charging case 1000 can represent different parameter values of the same parameter of the charging case 1000 by different durations of the indication sound.

[0141] 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 duration of the indication sound is negatively correlated with the remaining power, the duration of the indication sound at least includes a first duration, a second duration, and a third duration, where the first duration is less than the second duration, and the second duration is less than the third duration. The remaining power value of the charging case 1000 at least includes a first remaining power value, a second remaining power value, and a third remaining power value, where 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 moving distance represents that the cover 300 moves to the predetermined position, the duration of the indication sound is the first duration (e.g., 3 seconds), representing that the remaining power of the charging case 1000 is the first remaining power value (e.g., 90%); the duration of the indication sound is the second duration (e.g., 5 seconds), representing that the remaining power of the charging case 1000 is the second remaining power value (e.g., 80%); and the duration of the indication sound is the third duration (e.g., 10 seconds), representing that the remaining power of the charging case 1000 is the third remaining power value (e.g., 5%). Thus, the charging case 1000 can represent different parameter values of the same parameter of the charging case 1000 by different durations of the indication sound, so that the user can obtain different states of the charging case 1000 according to different durations of the indication sound.

[0142] Referring to Figure 5 and Figure 4 In some embodiments, the indication sound has different frequencies, and different frequencies represent different parameter values of the same parameter of the charging case 1000.

[0143] Specifically, the parameter of the indication sound includes the frequency of the indication sound. In the case where the moving distance represents that the cover 300 moves to the predetermined position, the state of the response component 630 is the triggered state, and the indication sound is emitted, the indication sound represents different parameter values of the same parameter of the charging case 1000 by different frequencies. At this time, the parameter of the charging case 1000 includes, but is not limited to, the consumed power of the charging case 1000, the remaining power, and the temperature, and correspondingly, the parameter value includes, but is not limited to, the consumed power value, the remaining power value, and the temperature value. The frequency and the different parameter values of the same parameter of the charging case 1000 can be positively correlated or negatively correlated.

[0144] 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 frequency of the indication sound is negatively correlated with the remaining power, the frequency of the indication sound at least includes a first frequency, a second frequency, and a third frequency, wherein the first frequency is less than the second frequency, and the second frequency is less than the third frequency. The remaining power value of the charging case 1000 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, when the frequency of the indication sound is the first frequency (20 HZ), it represents that the remaining power of the charging case 1000 is the first remaining power value (80%); when the frequency of the indication sound is the second frequency (40 HZ), it represents that the remaining power of the charging case 1000 is the second remaining power value (60%); and when the frequency of the indication sound is the third frequency (60 HZ), it represents that the remaining power of the charging case 1000 is the third remaining power value (40%). Thus, the charging case 1000 can represent different parameter values of the same parameter of the charging case 1000 through different frequencies of the indication sound, so that the user can obtain different states of the charging case 1000 according to different frequencies of the indication sound.

[0145] Referring to Figure 5 and Figure 4 In some embodiments, the response component 630 includes a plurality of buzzers 631, and the buzzers 631 are used to emit the indication sound. Different numbers of buzzers 631 emit the indication sound to represent different parameter values of the same parameter of the charging case 1000.

[0146] Specifically, the response component 630 includes a plurality of buzzers 631, and the number of the buzzers 631 is not limited. In the case where the movement distance represents that the cover 300 moves to the predetermined position, the state of the response component 630 is the triggered state and the indication sound is emitted, the response component 630 can represent different parameters of the charging case 1000 through the number of the buzzers 631 in the triggered state and emitting the indication sound. 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 buzzers 631 and the parameter values of the same parameter includes but is not limited to positive correlation and negative correlation.

[0147] For example, in the embodiment where the parameter of the charging case 1000 is temperature, the parameter value is temperature value, and the number of the buzzers 631 positively correlates with the temperature, the number of the buzzers 631 emitting the indication sound 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 moving distance represents that the cover 300 moves to the predetermined position, the number of the buzzers 631 emitting the indication sound 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 buzzers 631 emitting the indication sound 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 buzzers 631 emitting the indication sound 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 buzzers 631 in the response assembly 630 in the triggered state and emitting the indication light, so that the user can obtain different states of the charging case 1000 according to the number of the buzzers 631.

[0148] Referring to Figure 5 and Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 Figure 5 Figure 4 In some embodiments, the response assembly 630 includes a plurality of buzzers 631, and the buzzers 631 are configured to emit indication sounds, and the indication sounds of different buzzers 631 are configured to represent different parameters of the charging case 1000.

[0149] Specifically, the response component 630 includes a plurality of buzzers 631, and the number of the buzzers 631 is not limited. In the case that the moving distance representation cover 300 moves to the predetermined position, the state of the response component 630 is the triggering state and the indicating sound is emitted, different indicating sounds 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. In the case that different indicating sounds represent the parameters of the charging case 1000, the parameters of the indicating sounds used can be the same or different. For example, in the case that the response component 630 includes a first buzzer, a second buzzer and a third buzzer, 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, and the first parameter, the second parameter and the third parameter are different. In one of the embodiments, the indicating sound emitted by the first buzzer is used to represent the consumed power of the charging case 1000, the indicating sound emitted by the second buzzer is used to represent the remaining power of the charging case 1000, and the indicating sound emitted by the third buzzer is used to represent the temperature of the charging case 1000. In one example, the different durations of the indicating sound emitted by the first buzzer represent different consumed power values of the consumed power of the charging case 1000, the different frequencies of the indicating sound emitted by the second buzzer represent different remaining power values of the remaining power of the charging case 1000, and the different decibels of the indicating sound emitted by the third buzzer represent different temperature values of the temperature of the charging case 1000. The response component 630 represents different parameters of the charging case 1000 by the indicating sounds of different buzzers 631, so that the response component 630 can deliver at least one state of the charging case 1000, and enrich the delivered information of the response component 630.
