[0040] The following description provides specific application scenarios and requirements for this specification, with the goal of enabling those skilled in the art to make and use the contents of this specification. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of this specification. Therefore, this specification is not limited to the embodiments shown, but is intended to be accorded the broadest scope consistent with the claims.

[0041] The terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. For example, as used herein, the singular forms "a," "an," and "the" may also include the plural forms unless the context clearly indicates otherwise. When used in this specification, the terms "comprise," "include," and / or "contain" are intended to refer to the presence of the associated integers, steps, operations, elements, and / or components, but do not preclude the presence of one or more other features, integers, steps, operations, elements, components, and / or groups or the addition of other features, integers, steps, operations, elements, components, and / or groups in the system / method.

[0042] In this application, "X includes at least one of A, B, or C" means that X includes at least A, or X includes at least B, or X includes at least C. In other words, X can include only any combination of A, B, and C, or it can include any combination of A, B, and C as well as other possible contents / elements. The arbitrary combination of A, B, and C can be A, B, C, AB, AC, BC, or ABC.

[0043] In this application, unless explicitly stated otherwise, the association relationship between structures can be a direct association relationship or an indirect association relationship. For example, when describing "A is connected to B", unless it is explicitly stated that A is directly connected to B, it should be understood that A can be directly connected to B or indirectly connected to B; for another example, when describing "A is above B", unless it is explicitly stated that A is directly above B (AB are adjacent and A is above B), it should be understood that A can be directly above B or indirectly above B (AB is separated by other elements and A is above B). And so on.

[0044] These and other features of this specification, as well as the operation and function of the associated elements of the structure, and the economical assembly and manufacture of the components, can be significantly improved with consideration of the following description. The description also includes all figures and text referenced in the drawings herein, all of which form a part of this specification. However, it should be expressly understood that the drawings are for illustration and description purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not drawn to scale.

[0045] The wearable device provided in this application is a waterproof wearable device. The wearable device can provide a certain waterproof effect, so that the wearable device can be used in special scenarios to prevent water from entering the inside from the outside to a certain extent, such as scenes when it rains, scenes when it swims, and scenes when it falls into the water for a short time. The wearable device may include an AR / VR / MR head-mounted all-in-one, smart audio glasses, Bluetooth headsets, wearable speakers, smart watches, smart bracelets, smart rings, smart clothes, smart sports shoes, etc. For the convenience of demonstration, the following content is explained using the example of a wearable device being a waterproof headset. It should be noted that those skilled in the art should understand that wearable devices and others are also within the scope of protection of this specification.

[0046] The waterproof earphones can be any type of waterproof earphones. For example, the waterproof earphones can be wired. The receiver in the wired waterproof earphones can receive electrical signals from a media player via wired transmission, thereby converting the electrical signals into sound waves audible to the human ear. For example, the waterproof earphones can be wireless. The receiver in the wireless waterproof earphones can receive electrical signals from a media player via wireless transmission, thereby converting the electrical signals into sound waves audible to the human ear. The waterproof earphones can be air conduction waterproof earphones. Air conduction waterproof earphones can convert electrical signals into air vibration signals. The air vibration signals can be transmitted to the ear canal. The eardrum in the ear can convert the air vibration signals into sound. For another example, the waterproof earphones can be bone conduction waterproof earphones. Bone conduction waterproof earphones can convert electrical signals into mechanical vibration signals. The mechanical vibration signals can cause the skull to vibrate, causing the perilymph to produce fluctuations of the same frequency, and stimulating the cochlear cochlear organ to produce hearing. It should be noted that the waterproof earphones provided in this application include a data storage unit. In this case, the waterproof earphones can be independent of an external media player and can also play the audio data stored in the built-in data storage unit when no signal transmission is performed with the external media player. This specification does not limit the type of waterproof earphones.

[0047] As previously mentioned, the wearable device is a waterproof headset. Figure 1 shows an exploded view of a waterproof headset 001 according to some exemplary embodiments of this application. As shown in Figure 1, waterproof headset 001 may include a core assembly 100 and a main body 300. In some embodiments, waterproof headset 001 may also include a rear hanging assembly 500.

[0048] The core assembly 100 can also be called a speaker assembly. The core assembly 100 can convert electrical signals into sound waves that can be heard by humans. The number of core assemblies 100 can be one or two. When there is only one core assembly 100, the waterproof earphones 001 can be used in some application scenarios where stereo requirements are not particularly high, such as hearing aids for hearing-impaired patients, live broadcast prompting by hosts, etc. When the user wears the waterproof earphones 001, the core assembly 100 can be worn on the user's left ear or the user's right ear. When there are two core assemblies 100, when the user wears the waterproof earphones 001, the two core assemblies 100 are worn on different ears of the user respectively. At this time, both core assemblies 100 can make sound, thereby giving the waterproof earphones 001 a stereo sound effect, improving the user's favorability of the waterproof earphones 001. In some embodiments, the two core assemblies 100 can be set independently. That is, the two core assemblies 100 can exist independently and can be worn separately. For example, the two movement assemblies 100 can be worn on different ears, or on the ears of different users, making the waterproof earphones 001 more flexible to use. In this case, the two movement assemblies 100 can operate independently. In some embodiments, the two movement assemblies 100 can also be connected together (for example, via the back-hanging assembly 500). In this case, the two movement assemblies 100 can operate simultaneously and be controlled uniformly for better sound quality. In some embodiments, the movement assembly 100 can be an air conduction movement. In this case, when the user wears the waterproof earphones 001, the movement assembly 100 can be in-ear or open-ear. In some embodiments, the movement assembly 100 can also be a bone conduction movement. In this case, when the user wears the waterproof earphones 001, the movement assembly 100 can be mounted on the outside of the user's ear. For example, the movement assembly 100 can be mounted on the outside of the ear, close to the human skin, so that sound waves are transmitted to the inside of the ear through the vibration of the human skin and bones. In some embodiments, the movement assembly 100 can be a combination of an air conduction movement and a bone conduction movement.

[0049] The main body 300 can be electrically connected to the core assembly 100 to control the core assembly 100. In waterproof earphones 001, the main body 300 can be the ear hook component of the waterproof earphones 001. In some embodiments, the main body 300 can receive electrical signals sent by an external media player and transmit the electrical signals to the core assembly 100. The main body 300 can have a built-in data storage unit. In this case, the main body 300 can transmit audio data from the built-in data storage unit to the core assembly 100. There can be one or more main bodies 300. In some embodiments, each core assembly 100 can be connected to a main body 300. In some embodiments, the waterproof wearable device is a waterproof earphone 001. The waterproof earphone 001 can include two core assemblies 100, wherein the two core assemblies 100 can share a single main body 300. When the waterproof earphones 001 include two core assemblies 100 and two main bodies 300, the two core assemblies 100 are electrically connected to the two main bodies 300 respectively. In this case, the two main bodies 300 can be independently provided to independently control the core assembly 100. The two main bodies 300 can also be connected together, for example, by connecting the two main bodies 300 together through a cable assembly 500 to achieve unified control of the two core assemblies 100.

[0050] As shown in FIG1 , the main body 300 includes a housing 320 , electronic components 340 , and a charging port 380 . In some embodiments, the main body 300 may further include a control button 360 .

[0051] The silo 320 can be a mounting base for the electronic component 340. The silo 320 can be a thin-walled shell-like structure with a hollow interior. The electronic component 340 can be installed inside the silo 320. The shape of the silo 320 can be any shape to accommodate the installation of other components. The shape of the silo 320 can be ergonomic to facilitate user use. The material of the silo 320 can be any material, such as metal, plastic, polymer, etc. This specification does not limit the shape and material of the silo 320.

[0052] In some embodiments, the housing 320 can be integrally formed. In some embodiments, the housing 320 can include at least two housings. For example, the housing 320 can include two housings: a main housing 321 and a housing cover 323. The main housing 321 and the housing cover 323 are assembled together to form a hollow housing structure. In some embodiments, the housing 320 can also be composed of more than two housings assembled together, which is not described in detail in this specification. The main housing 321 and the housing cover 323 are thin-walled components. They can be assembled together to form a storage compartment. The storage compartment can accommodate other components and allow them to be installed within the compartment, thereby protecting them from dust. For example, the electronic component 340 can be installed within the housing 320, for example, within the storage compartment. The connection between the main housing 321 and the housing cover 323 can be sealed with sealant to enhance the waterproof performance of the housing 320.

[0053] The electronic component 340 may include a circuit board. The core assembly 100 may be electrically connected to the circuit board. The core assembly 100 and the circuit board may be electrically connected via a cable assembly 500. The circuit board may control the core assembly 100. The circuit board is a chip integrated circuit with an integrated waterproof headphone function. In some embodiments, the circuit board includes a radio frequency unit for receiving and transmitting signals, such as Bluetooth, NFC, Wi-Fi and other communication elements, to enable communication with an external media player. The circuit board also includes a data storage unit to store audio data. In some embodiments, the circuit board also includes a CPU unit for processing data and a DSP unit for audio decoding. The circuit board can be used for short-range wireless communication, audio transmission, data transmission, data storage, location services, device networks, and the like. This specification does not limit the type of circuit board. Specifically, the circuit board may include a flexible printed circuit board (FPC), a rigid printed circuit board (PCB), and a rigid-flex PCB. That is, the circuit board may be any circuit or processor capable of performing one or more functions, or any combination thereof.

[0054] In some embodiments, the main body 300 may further include a control button 360. The control button 360 may be mounted on the housing 320 and partially exposed outside the housing 320 for user operation. The control button 360 may be electrically connected to the circuit board. By operating the control button 360, the user can control the circuit board to turn the waterproof earphones 001 on and off, adjust the volume, switch modes, and perform other functions, thereby enhancing the intelligence of the waterproof earphones 001 and improving the user experience.

[0055] The main body 300 also includes a charging interface 380. When the waterproof earphones 001 include two main bodies 300, the charging interface 380 can be located in any one of the main bodies 300 and electrically connected to the electronic component 340. The charging interface 380 can be installed on the compartment body 320 and partially exposed outside the compartment body 320 to be electrically connected to the charging plug (the charging plug will be introduced later). The charging interface 380 can be electrically connected to the electronic component 340 to provide electrical energy to the electronic component 340. The electrical energy can be transmitted to other components, such as the movement assembly 100, through the electronic component 340. The fixed connection method between the charging interface 380 and the compartment body 320 can include any form, including but not limited to bonding, riveting, welding, threaded connection, snap connection, etc. The connection between the compartment body 320 and the charging interface 380 can also be sealed by a sealant to improve the waterproof performance of the waterproof earphones 001.

[0056] In some embodiments, the waterproof earphones 001 may further include a rear-mounted assembly 500. The rear-mounted assembly 500 may connect the two core assemblies 100. For example, when the two core assemblies 100 are electrically connected to the two main bodies 300, the rear-mounted assembly 500 may electrically connect the two main bodies 300. For another example, when the two core assemblies 100 share a main body 300, the main body 300 may be positioned adjacent to either core assembly 100, and the rear-mounted assembly 500 may electrically connect the main body 300 to the other core assembly 100.

[0057] In some embodiments, the rear hanging component 500 may include a cable. The cable can be any conductive wire, such as a wire. The cable is mainly used to achieve electrical connection between the various electronic components of the waterproof earphones 001. For example, when two core components 100 are electrically connected to two main bodies 300 respectively, the cable can electrically connect the two main bodies 300. For another example, when two core components 100 share a main body 300, the main body 300 can be close to any one of the two core components 100, and the cable can electrically connect the main body 300 to the other core component 100. The cable can be one strand or multiple strands. When there are multiple circuits that need to be electrically connected in the waterproof earphones 001, the cable can be set to multiple strands accordingly. For example, the cable can be set to any number of strands such as 1 strand, 2 strands, 3 strands, 5 strands, 6 strands, 8 strands, etc.

[0058] In some embodiments, the rear hanging component 500 may also include an elastic metal wire. The elastic metal wire can be designed in an arc shape to provide a certain clamping force for the user when wearing the waterproof earphones. For example, when the two core components 100 are electrically connected to the two main bodies 300 respectively, the two ends of the elastic metal wire can be connected to the two main bodies 300 respectively. At this time, when the user wears the waterproof earphones 001, the two main bodies 300 can be hung on the outside of the user's two ears respectively, and the rear hanging component 500 is used to be wrapped around the back of the user's head, and the two core components 100 are respectively located near the two ears. At this time, the elastic metal wire can provide a certain clamping force, so that the two core components 100 are close to the user's skin to improve wearing reliability.

[0059] In some embodiments, the waterproof earphones 001 may further include a protective cover 600. The protective cover 600 may be coated on the outer surface of the core assembly 100. The protective cover 600 may also be coated on the outer surface of the main body 300. The protective cover 600 may also be coated on the outer surface of the rear hanging assembly 500. The protective cover 600 may be integrally formed or may be formed by splicing multiple protective covers. The protective cover 600 may be sealed to the core assembly 100, the main body 300, and the rear hanging assembly 500 by sealant to enhance the waterproof performance of the waterproof earphones 001. The protective cover 600 may be made of a soft material with a certain degree of elasticity, such as soft silicone, rubber, etc.

[0060] It should be noted that the connection between the core assembly 100 and the main body 300 can also be sealed with a sealant to improve the waterproof performance of the waterproof earphone 001. Similarly, the connection between the main body 300 and the rear hanging assembly 500 can also be sealed with a sealant to improve the waterproof performance of the waterproof earphone 001.

[0061] Figure 2 shows a front view of a charging interface 380 provided according to some exemplary embodiments of the present application; Figure 3 shows a cross-sectional view AA of Figure 2; Figure 4 shows a bottom view of a charging interface 380 provided according to some exemplary embodiments of the present application; and Figure 5 shows a rear view of a charging interface 380 provided according to some exemplary embodiments of the present application. As shown in Figures 2 to 5, the charging interface 380 includes a charging socket 382, ​​a charging terminal 384, and a data transmission terminal 386. In some embodiments, the charging interface 380 may also include an adapter plate 387. In some embodiments, the charging interface 380 may also include a magnetic device 388.

[0062] The charging socket 382 can be the base of the charging interface 380. Other components of the charging interface 380 (such as the charging terminal 384, the data transmission terminal 386, the adapter plate 387, and the magnetic device 388) can use the charging socket 382 as a base and be installed on the charging socket 382. The charging socket 382 is installed on the housing 320 of the main body 300. To improve the waterproof performance of the waterproof earphones 001, the charging socket 382 and the waterproof earphones 001 can be sealed together using sealant. One side of the charging socket 382 can be exposed outside the housing 320 for connection to an external charging plug. The other side of the charging socket 382 can face the interior of the housing 320 or extend deep into the housing 320. The charging socket 382 can be a thin-walled plate-like structure and can be molded as a single piece or molded separately and then assembled. During assembly, the various parts are sealed and bonded using sealant. The shape of the charging socket 382 can be arbitrary to accommodate the installation of other components. The material base of the charging socket 382 can be made of insulating materials, such as plastic, polymer materials, resin, etc., and the shape can be rectangular, circular or other irregular shapes.

[0063] The charging terminal 384 is mounted on the charging socket 382. Specifically, the charging socket 382 is provided with a hole, through which the charging terminal 384 is inserted. Specifically, one end of the charging terminal 384 is positioned on one side of the hole, and the other end is positioned on the other side. The charging terminal 384 and the contact portion are sealed to the hole using a sealant. The charging terminal 382 can be electrically connected to the electronic component 340. Specifically, the charging terminal 382 can be electrically connected to the electronic component 340 to provide power to the electronic component 340. When the charging interface 380 is connected to an external charging plug for charging, the charging terminal 384 can be electrically connected to the power source of the charging plug. The charging terminal 384 may include a positive terminal 3841 and a negative terminal 3843. The positive and negative terminals 3841 and 3843 are at least partially exposed outside the charging socket 382. When the charging interface 380 is connected to an external charging plug for charging, the positive terminal 3841 is electrically connected to the positive terminal of the external power source. The negative terminal 3843 is electrically connected to the negative pole of the external power supply. The positive terminal 3841 and the negative terminal 3843 are spaced apart to prevent a short circuit between the positive and negative poles. In a scenario where the user is swimming, although a large amount of water on the charging port 380 is cleaned off after swimming ashore, a small amount of water still remains attached to the positive terminal 3841 and the negative terminal 3843. Specifically, when the user holds the rear hanging component 500 and shakes off the water attached to the waterproof earphones 001, the rear hanging component 500 rotates around the wrist. At this time, the water accumulated in the charging port 380 will be subjected to centrifugal force, wherein the centrifugal force exerted on a large amount of water is greater than the adhesion between the water and the charging port 380 and detaches from the charging port 380, while the centrifugal force exerted on a small amount of water is less than the adhesion between the water and the charging port 380 and remains on the surface of the charging port 380. The water remaining on the surface of the charging port 380 can easily connect the positive terminal 3841 and the negative terminal 3843. In order to prevent the positive and negative poles from being short-circuited by water attached to the positive terminal 3841 and the negative terminal 3843 when the charging interface 382 is charging, the positive terminal 3841 and the negative terminal 3843 need to be spaced apart so that the water attached to the positive terminal 3841 and the negative terminal 3843 cannot communicate.

[0064] The data transmission terminal 386 can be mounted on the charging socket 382. The data transmission terminal 386 can be electrically connected to the electronic component 340. For example, the data transmission terminal 386 can be electrically connected to a data storage unit on a circuit board to perform data storage with the data storage unit. The data transmission terminal 386 can include a first terminal 3861 and a second terminal 3863. When the charging interface 380 is connected to a charging plug, the data transmission terminal 386 can communicate with the electronic device connected to the charging plug to enable data transfer between the electronic device and the storage unit.

[0065] It should be noted that the charging terminal 384 and the data transmission terminal 386 can perform corresponding functions separately or jointly. Specifically, the charging terminal 384 and the data transmission terminal 386 can perform charging functions and data transmission functions separately; the charging terminal 384 can perform the charging function, and the charging terminal 384 and the data transmission terminal 386 can perform the data transmission function together.

[0066] In some embodiments, the charging port 380 further includes an adapter plate 387. The adapter plate 387 can be located on the side of the charging socket 382 facing the interior of the wearable device (e.g., the interior of the housing 320). The adapter plate 387 can be sealed to the charging socket 382 to prevent water from passing through the charging socket 382 from the outside and entering the interior of the wearable device (e.g., the interior of the housing 320). The adapter plate 387 can be sealed to the charging socket 382 using a sealant.

[0067] As previously described, the charging terminals 384 and the data transmission terminals 386 can be electrically connected to the electronic component 340. Specifically, the charging terminals 384 and the data transmission terminals 386 can be electrically connected to the electronic component 340 via a cable. To ensure the seal between the adapter plate 387 and the charging socket 382, ​​the charging terminals 384 and the data transmission terminals 386 can be welded to the cable on the adapter plate 387. The surface of the adapter plate 387 facing the interior of the chamber 320 is covered with sealant to seal the welds between the charging terminals 384 and the data transmission terminals 386 and the cable.

[0068] In some embodiments, the charging interface 380 further includes a magnetic device 388. The magnetic device 388 can be installed on the side of the charging socket 382 facing the interior of the wearable device (such as the interior of the compartment 320). In which, the charging plug is provided with an adsorption device. When the charging interface 380 is connected to the charging plug, the magnetic device 388 and the adsorption device generate an adsorption force, thereby fastening the charging interface 380 and the charging plug together. The charging interface 380 and the charging plug are connected through the adsorption device and the magnetic device 388, which not only fixes the charging interface 380 and the charging plug, but also allows the charging interface 380 to be quickly aligned with the charging plug through the corresponding positions of the adsorption device and the magnetic device 388, thereby achieving accurate connection and increasing the reliability of the connection and the convenience of operation. The adsorption device and the magnetic device 388 can be two magnets that adsorb each other. It should be noted that the magnetic device 388 can be provided on the charging plug, and the adsorption device can be provided on the charging interface 380, which is not limited here.

[0069] The magnetic device 388 can be set at any position of the charging interface 380, such as on the charging socket 382. Furthermore, the magnetic device 388 can be set at any position of the charging socket 382, ​​such as the charging terminal 384 and the data transmission terminal 386, or between the positive terminal 3841 and the negative terminal 3843.

[0070] As shown in Figures 2 to 5, the charging hub 382 includes a charging hub base 3825, a first mounting portion 3821, a second mounting portion 3822, and a third mounting portion 3823. In some embodiments, the charging hub base 3825, the first mounting portion 3821, the second mounting portion 3822, and the third mounting portion 3823 are a whole, that is, integrally formed. In some embodiments, the charging hub base 3825, the first mounting portion 3821, the second mounting portion 3822, and the third mounting portion 3823 are separate and fixedly connected together. Methods of fixed connection include but are not limited to bonding, welding, riveting, threaded connection, and the like. In the embodiments shown in Figures 2 to 5, the charging hub base 3825, the first mounting portion 3821, the second mounting portion 3822, and the third mounting portion 3823 are integrally formed.

[0071] As mentioned above, the charging socket 382 can be installed on the warehouse body 320. Specifically, the charging socket 382 can be installed on the warehouse body 320 through the charging socket base 3825. The charging socket base 3825 can be sealed with the warehouse body 320 by a sealant. The charging socket base 3825 includes a first side 3825-1 and a second side 3825-2. The first side 3825-1 and the second side 3825-2 are arranged opposite to each other. The first side 3825-1 faces the outside of the wearable device (such as the waterproof earphones 001). The second side 3825-2 faces the inside of the wearable device (such as the waterproof earphones 001). When the charging interface 380 is connected to a third-party charging plug, the third-party charging plug is connected to the charging interface 380 from the first side 3825-1.

[0072] In some embodiments, the charging hub base 3825 further includes a side wall 3825-5. The side wall 3825-5 is located at the edge of the charging hub base 3825, and protrudes from the first side 3825-1 of the charging hub base 3825 in a direction away from the charging hub base 3825 to form a positioning groove for positioning when connected to the charging plug. The side wall 3825-5 can be located at the edge of the charging hub base 3825 and form a closed groove along the edge. When the charging hub base 3825 is installed with the warehouse body 320, the outer side of the side wall 3825-5 can be used for installation with the warehouse body 320 and sealed with sealant.

[0073] As mentioned above, the adapter plate 387 can be sealed and connected to the side of the charging base 382 facing the inside of the wearable device. Specifically, the adapter plate 387 can be sealed and connected to one side of the second side 3825-2 of the charging base base 3825. For example, the second side 3825-2 of the charging base base 3825 can have a protrusion extending away from the second side 3825-2. The adapter plate 387 can be sealed and connected to the protrusion to seal the charging terminal 384 and the data transmission terminal 386 in the space formed by the protrusion and the adapter plate 387. As mentioned above, the magnetic device 388 can be installed on the side of the charging base 382 facing the inside of the wearable device (such as the inside of the tank body 320). Specifically, the magnetic device 388 can be installed on the second side 3825-2 of the charging base base 3825. For example, the magnetic device 388 can be installed on the periphery of the protrusion.

[0074] The first mounting portion 3821, the second mounting portion 3822, and the third mounting portion 3823 are located on the first side 3825-1 of the charging socket base 3825 and are connected to the first side 3825-1. The positive terminal 3841 is fixedly mounted on the first mounting portion 3821. The first mounting portion 3821 is provided with a mounting hole. The positive terminal 3841 can be fixedly mounted in the mounting hole on the first mounting portion 3821, with the positive terminal 3841 at least partially exposed outside the first mounting portion 3821 for electrical connection to the charging plug. Methods for securing the positive terminal 3841 to the first mounting portion 3821 include, but are not limited to, bonding, snapping, welding, and interference fit. To enhance the waterproof performance of the charging interface 380, a sealant can be filled between the positive terminal 3841 and the mounting hole of the first mounting portion 3821 to form a sealed connection. The negative terminal 3843 is mounted on the second mounting portion 3822. The second mounting portion 3822 is provided with a mounting hole. The negative terminal 3843 can be fixedly mounted in the mounting hole on the second mounting portion 3822, with the negative terminal 3843 at least partially exposed outside the second mounting portion 3822 for electrical connection to the charging plug. Methods for securing the negative terminal 3843 to the second mounting portion 3822 include, but are not limited to, bonding, snap-fitting, welding, and interference fit. To enhance the waterproof performance of the charging interface 380, a sealant can be filled between the negative terminal 3843 and the mounting hole in the second mounting portion 3822 to form a sealed connection. The data transmission terminal 386 is mounted on the third mounting portion 3823. The third mounting portion 3823 is provided with a mounting hole. The data transmission terminal 386 can be fixedly mounted in the mounting hole on the third mounting portion 3823, with the data transmission terminal 386 at least partially exposed outside the third mounting portion 3823 for electrical connection to the charging plug. Methods for securing the data transmission terminal 386 to the third mounting portion 3823 include, but are not limited to, bonding, snap-fitting, welding, and interference fit. To enhance the waterproof performance of charging port 380, sealant can be filled between data transmission terminal 386 and the mounting hole of third mounting portion 3823 to form a sealed connection. As previously mentioned, data transmission terminal 386 includes a first terminal 3861 and a second terminal 3863. Accordingly, third mounting portion 3823 can be provided with two mounting holes, one for mounting first terminal 3861 and the other for mounting second terminal 3863.

[0075] As previously mentioned, to prevent water from adhering to the positive and negative terminals 3841 and 3843 during charging, the positive and negative terminals 3841 and 3843 must be spaced apart to prevent any water from flowing between them. Therefore, the first mounting portion 3821 and the second mounting portion 3822 are spaced apart to prevent any water from flowing between the first mounting portion 3821 and the negative terminal 3843. This prevents any water from flowing between the first mounting portion 3821 and the negative terminal 3843, which may be adhering to the charging plug. Since the positive terminal 3841 is at least partially exposed outside the first mounting portion 3821 and the negative terminal 3843 is at least partially exposed outside the second mounting portion 3822, when water attached to the surface of the first mounting portion 3821 facing the charging plug and water attached to the surface of the second mounting portion 3822 facing the third-party charging plug are disconnected, the water attached to the portion of the positive terminal 3841 exposed outside the first mounting portion 3821 and the water attached to the portion of the negative terminal 3843 exposed outside the second mounting portion 3822 are also disconnected.

[0076] The spacing between the first mounting portion 3821 and the second mounting portion 3822 can be achieved in a variety of ways. In some embodiments, the spacing between the first mounting portion 3821 and the second mounting portion 3822 can be achieved by providing a gap between the first mounting portion 3821 and the second mounting portion 3822. In some embodiments, the spacing between the first mounting portion 3821 and the second mounting portion 3822 can be achieved by providing an insulating baffle between the first mounting portion 3821 and the second mounting portion 3822. In the embodiments shown in Figures 2 to 5, the spacing between the first mounting portion 3821 and the second mounting portion 3822 can be achieved by providing a gap between the first mounting portion 3821 and the second mounting portion 3822. Other embodiments of the spacing between the first mounting portion 3821 and the second mounting portion 3822 will be described in detail later.

[0077] As shown in Figures 2 to 5, at least one of the first mounting portion 3821 and the second mounting portion 3822 protrudes in a direction away from the first side 3825-1, thereby forming a gap 3828 between the first mounting portion 3821 and the second mounting portion 3822. The gap 3828 allows the first mounting portion 3821 and the second mounting portion 3822 to be spaced apart. For example, the first mounting portion 3821 may protrude in a direction away from the first side 3825-1, while the second mounting portion 3822 does not. For example, the second mounting portion 3822 may protrude in a direction away from the first side 3825-1, while the first mounting portion 3821 does not. For another example, both the first mounting portion 3821 and the second mounting portion 3822 may protrude in a direction away from the first side 3825-1.

[0078] When both the first mounting portion 3821 and the second mounting portion 3822 protrude in a direction away from the first side 3825-1, the protrusions of the first mounting portion 3821 and the second mounting portion 3822 may be the same height or different heights. When the charging base 3825 includes a sidewall 3825-5 and the first mounting portion 3821 and the second mounting portion 3822 protrude at the same height, the protrusions of the first mounting portion 3821 and the second mounting portion 3822 may be higher than the height of the sidewall 3825-5, or may be equal to or lower than the height of the sidewall 3825-5. In the scenario described above, after the user swims ashore, a large amount of water on the charging port 380 is cleared, but a small amount of water still remains attached to the first mounting portion 3821 and the second mounting portion 3822. The height of the protrusions of the first mounting portion 3821 and the second mounting portion 3822 may be in any relationship to the height of the sidewall 3825-5, such as higher than, lower than, or equal to. At this point, water cannot flow between the surfaces of the first mounting portion 3821 and the second mounting portion 3822 facing the charging plug. During charging, the positive terminal 3841 and the negative terminal 3843 mounted on the first and second mounting portions 3821, 3822 will not connect, causing a short circuit. In some scenarios, a large amount of water could accumulate within the charging receptacle base 3825, potentially flooding both the surfaces of the first and second mounting portions 3821, 3822 facing the charging plug. In this case, the protrusions of the first and second mounting portions 3821, 3822 are higher than the height of the sidewall 3825-5. When water enters and accumulates on the charging socket base 3825, the surface of the first mounting portion 3821 facing the charging plug and the surface of the second mounting portion 3822 facing the charging plug will not be submerged in water, that is, the water stains in the side wall 3825-5 cannot be connected, and the positive terminal 3841 and the negative terminal 3843 installed on the first mounting portion 3821 and the second mounting portion 3822 will not be connected to form a short circuit during charging.

[0079] When the charging socket base 3825 includes sidewalls 3825-5, and the protrusions of the first and second mounting portions 3821, 3822 have different heights, the higher protrusion of the first or second mounting portion 3821, 3822 should be higher than the height of the sidewalls 3825-5. In this case, if water enters and accumulates within the charging socket base 3825, the surface of the first and second mounting portions 3821, 3822 facing the charging plug will not be simultaneously submerged in water. Furthermore, the positive and negative terminals 3841, 3843 mounted on the first and second mounting portions 3821, 3822 will not connect to form a short circuit during charging.

[0080] To reduce the likelihood of water adhering to the surface of the first mounting portion 3821 facing the charging plug and water adhering to the surface of the second mounting portion 3822 facing the charging plug communicating with each other, the gap 3828 between the first mounting portion 3821 and the second mounting portion 3822 should be as large as possible within the permitted size range. The larger the gap 3828, the more water it can accommodate, making it less likely that water adhering to the surface of the first mounting portion 3821 facing the charging plug and water adhering to the surface of the second mounting portion 3822 facing the charging plug will communicate with each other. In some embodiments, the size of gap 3828 is related to the material of the first mounting portion 3821 and the second mounting portion 3822. For example, the first mounting portion 3821 and the second mounting portion 3822 may be made of a hydrophobic material such as polyolefin, polycarbonate, polyamide, polyacrylonitrile, polyester, fluorinated polyethylene, fluorocarbon wax, etc. Furthermore, the roughness of the surface of the first mounting portion 3821 and the surface of the second mounting portion 3822 facing the charging plug is preferably as small as possible within an allowable range, thereby creating a glossy surface on the surface of the first mounting portion 3821 and the surface of the second mounting portion 3822 facing the charging plug, thereby enhancing hydrophobicity. Furthermore, the surface of the first mounting portion 3821 and the surface of the second mounting portion 3822 facing the charging plug can be nano-treated to further enhance hydrophobicity.

[0081] In some embodiments, hydrophobicity can be measured by a contact angle measurement method. Furthermore, the contact angle can be calculated based on the Young-Laplace equation and the concept of surface tension. Specifically, the surface energy of the water droplet with the first mounting portion 3821 facing the surface of the charging plug and the second mounting portion 3822 facing the surface of the charging plug can be measured, and the contact angle can be calculated based on the Young-Laplace equation. The contact angle can also be measured directly. Specifically, clean and dry the first mounting portion 3821 facing the surface of the charging plug and the second mounting portion 3822 facing the surface of the charging plug to ensure that there are no impurities and dirt. Then, use a dropper or syringe to carefully drop a drop of water on the surface, use a microscope or camera to record the morphology of the droplet on the surface, and measure the angle between the water droplet and the surface contact line. The measured angle is the contact angle of the water droplet.

[0082] If the contact angle between the water droplet and the surface is large, it indicates that the surface has good hydrophobicity, that is, the water droplet is difficult to spread on the surface. For example, if the water droplet forms a large contact angle on the surface of the first mounting portion 3821, it indicates that the first mounting portion 3821 has good hydrophobicity. For another example, if the water droplet forms a large contact angle on the surface of the second mounting portion 3822, the second mounting portion 3822 has good hydrophobicity. For another example, if the water droplet forms a large contact angle on the surface of the gap 3828, it indicates that the surface of the gap 3828 has good hydrophobicity. Among them, the contact angle of the water droplet is at least 60°, such as 60°, 70°, 80°, 90°, 100°, etc. Those skilled in the art should understand that other contact angle measurement methods are also within the scope of protection of this specification.

[0083] It should be noted that the above contact angle value range and measurement method are applicable to any structure with water droplets attached to the surface described in this specification, such as the third mounting portion 3823, the gap 3828, the sidewall 3825-5, etc. Specifically, the contact angle on the surface of the first mounting portion 3821 is at least 60°, and / or the contact angle on the surface of the second mounting portion 3822 is at least 60°, and / or the contact angle on the surface of the gap 3828 is at least 60°. In other words, the contact angles on the surfaces of the first mounting portion 3821, the second mounting portion 3822, and the gap 3828 can all be at least 60°, or they can each be at least 60°. When at least one of the contact angles on the surfaces of the first mounting portion 3821, the second mounting portion 3822, and the gap 3828 is at least 60°, the water droplets on the surface of the first mounting portion and the water droplets on the surface of the second mounting portion will not be connected, thus preventing a short circuit.

[0084] The more easily water adheres to the material of first mounting portion 3821 and second mounting portion 3822, the larger the size of gap 3828. In some embodiments, to prevent water from flowing between the surface of first mounting portion 3821 facing the charging plug and the surface of second mounting portion 3822 facing the charging plug, gap 3828 has a depth greater than 0.6 mm and a width greater than 0.6 mm. The width of gap 3828 can be oriented along the alignment of first mounting portion 3821 and second mounting portion 3822. The depth of gap 3828 can be oriented along the protrusions of first mounting portion 3821 and second mounting portion 3822.

[0085] In some embodiments, to increase the width of gap 3828, the first mounting portion 3821 and the second mounting portion 3822 can be arranged in the longitudinal direction of the charging base 3825 to increase the distance between the positive terminal 3841 and the negative terminal 3843. In addition, to further increase the width of gap 3828, the third mounting portion 3823 can be arranged between the first mounting portion 3821 and the second mounting portion 3822 to serve as a partition between the first mounting portion 3821 and the second mounting portion 3822. In some embodiments, the first terminal 3861 and the second terminal 3863 can be arranged in the width direction of the charging base 3825 to reduce the overall size of the charging base 382.

[0086] In some embodiments, to reduce manufacturing difficulty and enhance ease of use, the third mounting portion 3823 may be integrally connected to the first mounting portion 3821 or the second mounting portion 3822. In this case, the third mounting portion 3823 may also protrude in a direction away from the first side 3825-1, and the height of the protrusion may be the same as that of the first mounting portion 3821 or the second mounting portion 3822 to which it is connected.

[0087] The present application also provides a charging plug, which is connected to the above-mentioned charging interface 380 during operation. The charging interface 380 is connected to an external power supply device and / or data transmission device through the charging plug. Figure 6 shows a main view of a charging plug 600 provided according to some exemplary embodiments of the present application; Figure 7 shows a cross-sectional view BB of Figure 6; and Figure 8 shows a cross-sectional view of a charging interface 380 provided according to some exemplary embodiments of the present application connected to the charging plug 600. As shown in Figures 6 to 8, the charging plug 600 includes a charging compartment 620, a charging probe 640, and a data transmission probe 660. In some embodiments, the charging plug 600 also includes a charging circuit board assembly 670. In some implementations, the charging plug also includes a transmission interface 680. In some embodiments, the charging plug 600 also includes an adsorption device 690.

[0088] Charging probe 640 includes a positive probe 641 and a negative probe 643. When charging port 380 is connected to charging plug 600, positive terminal 3841 contacts positive probe 641 to achieve electrical connection. Negative terminal 3843 contacts negative probe 643 to achieve electrical connection. Positive probe 641 and negative probe 643 can be elastic probes to ensure reliable contact between positive terminal 3841 and positive probe 641, and between negative terminal 3843 and negative probe 643, when charging port 380 is connected to charging plug 600.

[0089] The data transmission probe 660 includes a first probe 661 and a second probe 663. When the charging interface 380 is connected to the charging plug 600, the first terminal 3861 contacts the first probe 661 to achieve electrical connection. The second terminal 3863 contacts the second probe 663 to achieve electrical connection. The first and second probes 661 and 663 can be resilient probes, ensuring reliable contact between the first terminal 3861 and the first probe 661, and between the second terminal 3863 and the second probe 663, when the charging interface 380 is connected to the charging plug 600.

[0090] The charging compartment 620 can be a mounting base for the charging probe 640 and the data transmission probe 660. The charging compartment 620 can be a thin-walled plate-like structure. The charging probe 640 and the data transmission probe 660 can be mounted on the charging compartment 620. The shape of the charging compartment 620 can be any shape to accommodate the installation of other components. The material base of the charging compartment 620 can be an insulating material, such as plastic, polymer material, resin, etc., and the shape can be rectangular. The shape of the charging compartment 620 can be adapted to the shape of the charging socket 382.

[0091] The charging compartment 620 includes a charging compartment base 625, a fourth mounting portion 621, a fifth mounting portion 622, and a sixth mounting portion 623. The charging compartment base 625 can serve as a carrier for the remaining components, such as the charging probe 640, the data transmission probe 660, the fourth mounting portion 621, the fifth mounting portion 622, and the sixth mounting portion 623.

[0092] The fourth mounting portion 621, the fifth mounting portion 622 and the sixth mounting portion 623 are connected to the side of the charging compartment base 625 facing the outside (charging interface 380). The fourth mounting portion 621, the fifth mounting portion 622 and the sixth mounting portion 623 can be integrally formed with the charging compartment base 625. The positive probe 641 can be mounted on the fourth mounting portion 621. The negative probe 643 can be mounted on the fifth mounting portion 622. The data transmission probe 660 can be mounted on the sixth mounting portion 623 as an example. In order to achieve accurate connection between the charging interface 380 and the charging plug 600, the first mounting portion 3821 matches the position, shape and size of the fourth mounting portion 621. The second mounting portion 3822 matches the position, shape and size of the fifth mounting portion 622. The third mounting portion 3823 matches the position, shape and size of the sixth mounting portion 623.

[0093] In some embodiments, the charging compartment 620 may further include a baffle 624. The baffle 624 is disposed between the fourth mounting portion 621 and the fifth mounting portion 622. The baffle 624 may protrude relative to the fourth mounting portion 621 and the fifth mounting portion 622 in a direction away from the fourth mounting portion 621 and the fifth mounting portion 622. When the first mounting portion 3821 and the second mounting portion 3822 are spaced apart by a gap 3828, when the charging interface 380 is connected to the charging plug 600, the baffle 624 may be inserted into the gap 3828 between the first mounting portion 3821 and the second mounting portion 3822, further preventing water adhering to the surfaces of the first mounting portion 3821 and the second mounting portion 3822 from flowing, thereby preventing the positive terminal 3841 and the negative terminal 3843 from short-circuiting during charging. The baffle 624 may be made of an insulating material.

[0094] In some embodiments, the charging plug 600 further includes a charging circuit board assembly 670 , which is mounted on the charging compartment 620 and electrically connected to the charging probe 640 and the data transmission probe 660 .

[0095] One end of the transmission interface 680 is electrically connected to the charging circuit board assembly 670 , and the other end is used to connect to an external power supply device and / or data transmission device.

[0096] When the charging interface 380 is connected to the charging plug 600 , the adsorption device 690 can be adsorbed together with the magnetic device 388 .

[0097] As previously mentioned, the spacing between the first mounting portion 3821 and the second mounting portion 3822 can also be achieved through other means, such as by providing an insulating barrier between the first mounting portion 3821 and the second mounting portion 3822. FIG. 9 illustrates a cross-sectional view of another charging interface 380 provided according to some exemplary embodiments of the present application. For ease of description, the charging interface shown in FIG. 9 is defined as charging interface 380a. As shown in FIG. 9 , an insulating plate 3829 can be provided between the first mounting portion 3821 and the second mounting portion 3822 in the charging interface 380a.

[0098] The charging socket 382 also includes an insulating plate 3829. The insulating plate 3829 is positioned between the first mounting portion 3821 and the second mounting portion 3822 and protrudes away from the first side 3825-1 relative to the first and second mounting portions 3821, 3822, so that the first and second mounting portions 3821, 3822 are spaced apart. This prevents water adhering to the surface of the first mounting portion 3821 facing the charging plug from connecting to water adhering to the surface of the second mounting portion 3822 facing the charging plug. Furthermore, the positive terminal 3841 and the negative terminal 3843 attached to the first and second mounting portions 3821, 3822 are also disconnected, thereby preventing a short circuit when the charging connector 380a is connected to the charging plug.

[0099] Furthermore, the insulating plate 3829 can be straight or curved. When the insulating plate 3829 is curved, the center of curvature of the insulating plate 3829 can be positioned away from the rear mount assembly 500 to drain water and prevent a short circuit when the charging connector 380a is connected to the charging plug.

[0100] To reduce the possibility of water adhering to the surface of the first mounting portion 3821 facing the charging plug and water adhering to the surface of the second mounting portion 3822 facing the charging plug communicating with each other, the insulating plate 3829 between the first mounting portion 3821 and the second mounting portion 3822 should be as large as possible within the permitted size range. The larger the insulating plate 3829, the less likely water adhering to the surfaces of the first mounting portion 3821 and the second mounting portion 3822 facing the charging plug will communicate with each other. In some embodiments, the size of the insulating plate 3829 is related to the material of the first and second mounting portions 3821 and 3822. The more easily water adhering to the material of the first and second mounting portions 3821 and 3822 is achieved, the larger the insulating plate 3829 should be. In some embodiments, to prevent water adhering to the surface of the first and second mounting portions 3821 and 3822 facing the charging plug from communicating with each other, the height of the insulating plate 3829 raised relative to the first and second mounting portions 3821 and 3822 should be greater than 0.6 mm. In some embodiments, the thickness of the insulating plate 3829 is greater than 0.6 mm.

[0101] To further improve waterproofing, insulating plate 3829 can be made of a hydrophobic material. Furthermore, the contact angle of a water droplet adhering to insulating plate 3829 is at least 60°, for example, 60°, 70°, 80°, 90°, 100°, and so on. The method for measuring the contact angle of a water droplet adhering to insulating plate 3829 is consistent with the aforementioned measurement method and is not further described here. Those skilled in the art will appreciate that other contact angle measurement methods are also within the scope of this specification.

[0102] The contact angle of the surface of the first mounting portion 3821 is at least 60°, and / or the contact angle of the surface of the second mounting portion 3822 is at least 60°, and / or the contact angle of the surface of the insulating plate 3829 is at least 60°. In other words, the contact angles of the first mounting portion 3821, the second mounting portion 3822, and the insulating plate 3829 can all be at least 60°, or they can each be at least 60°. When at least one of the contact angles of the first mounting portion 3821, the second mounting portion 3822, and the insulating plate 3829 is at least 60°, water stains on the surface of the first mounting portion 3821 and the second mounting portion 3822 will not connect, preventing a short circuit.

[0103] It should be noted that, to mate with the charging port 380a, the charging plug has a groove between the fourth mounting portion 621 and the fifth mounting portion 622. When the charging port 380a is connected to the charging plug, the insulating plate 3829 is positioned within the groove. The insulating plate 3829 mates with the groove, allowing for positioning of the charging port 380a when connected to the charging plug. This matching can be achieved by matching the shape and size of the mating surfaces of the insulating plate 3829 and the groove. When mated, the insulating plate 3829 snaps into place.

[0104] In some embodiments, the spacing between the first mounting portion 3821 and the second mounting portion 3822 can be achieved by positioning a third mounting portion 3823 between the first mounting portion 3821 and the second mounting portion 3822. Figure 10 shows a cross-sectional view of another charging interface 380 provided according to some exemplary embodiments of the present application. For ease of description, the charging interface shown in Figure 10 is referred to as charging interface 380b. As shown in Figure 10, the third mounting portion 3823 is located between the first mounting portion 3821 and the second mounting portion 3822. The third mounting portion 3823 protrudes relative to the first mounting portion 3821 and the second mounting portion 3822 in a direction away from the first side 3825-1, so that the first mounting portion 3821 and the second mounting portion 3822 are separated by the third mounting portion 3823. In this case, the third mounting portion 3823 can function as the aforementioned insulating plate 3829. The principle for preventing short circuits is previously described and will not be further elaborated here.

[0105] FIG11 shows a cross-sectional view of another charging interface 380 provided according to some exemplary embodiments of the present application. For the convenience of description, we define the charging interface shown in FIG10 as a charging interface 380c. As shown in FIG11 , the third mounting portion 3823 is recessed relative to the first mounting portion 3821 and the second mounting portion 3822 in a direction close to the first side 3825-1 to form a gap 3828 between the first mounting portion 3821 and the second mounting portion 3822, so that the first mounting portion 3821 and the second mounting portion 3822 are spaced apart. At this time, the recess at the third mounting portion 3823 can serve as the aforementioned gap 3828. The principle of avoiding the formation of a short circuit is as described above and will not be repeated here.

[0106] The sealants used for the above bonding include instant glue (such as 502 glue), epoxy resin bonding, anaerobic glue, UV glue (ultraviolet light curing type), hot melt adhesive, pressure sensitive adhesive, latex, silicone and the like.

[0107] In summary, this specification provides a charging interface 380 and a wearable device. Multiple mounting portions are provided on the charging socket 382 of the charging interface 380. A first mounting portion 3821 and a second mounting portion 3822 for mounting the positive terminal 3841 and the negative terminal 3843 of the charging terminal 384 are spaced apart from each other, thereby preventing the flow of water adhering to the first mounting portion 3821 and the second mounting portion 3822. In this case, when water adhering to the positive terminal 3841 and the negative terminal 3843 is present, the water adhering to the positive terminal 3841 and the negative terminal 3843 is not connected because the first mounting portion 3821 and the second mounting portion 3822 are spaced apart from each other. When charging port 380 is charging, the positive terminal 3841 and the negative terminal 3843 will not short-circuit due to water adhering to the surface, thereby improving the safety performance of charging port 380 and expanding the use scenarios of wearable devices. Even if the wearable device is used underwater and the positive terminal 3841 and the negative terminal 3843 are stained with water, it will not cause a short circuit in charging port 380 during charging. At the same time, the charging port 380 and wearable device provided by this application can enhance the user experience. After using the wearable device underwater, the user does not need to wipe, clean, or dry the water in the charging port 380 before charging, and can charge it, which greatly improves the convenience of use.
