Description

Technical Field

[0001] This application relates to the field of waterproof wearable device technology, and more particularly to a charging interface and a wearable device. Background Technology

[0002] With the development of technology, wearable devices are becoming increasingly popular, such as wearable smart glasses, smartwatches, and headphones. Wearable devices are typically equipped with rechargeable batteries and charging ports. The use cases for wearable devices are very wide-ranging. Among these scenarios, some involve contact with significant amounts of water, such as when using wearable devices outdoors in the rain or while swimming. In these situations, the wearable device may come into contact with water, and the charging port often becomes wet. Therefore, preventing short circuits in the charging port during charging is a pressing issue that needs to be addressed. Summary of the Invention

[0003] In a first aspect, embodiments of this application provide a charging interface for a wearable device, including a charging female connector, a charging terminal, and a data transmission terminal. The charging female connector includes a charging female connector base, a first mounting portion, a second mounting portion, and a third mounting portion. The first mounting portion, the second mounting portion, and the third mounting portion are connected to a first side of the charging female connector base, wherein the first side faces the outside of the wearable device. A third-party charging plug connects to the charging interface from the first side. The first mounting portion and the second mounting portion are spaced apart, such that water adhering to the surface of the first mounting portion facing the charging plug and water adhering to the surface of the second mounting portion facing the charging plug are not in communication.

[0016] According to some embodiments of this application, the charging interface further includes a data transmission terminal, which is mounted on the third mounting portion. The third mounting portion is located between the first mounting portion and the second mounting portion. The third mounting portion protrudes away from the first side relative to the first mounting portion and the second mounting portion, such that the first mounting portion and the second mounting portion are spaced apart. Alternatively, the third mounting portion is recessed towards the first side relative to the first mounting portion and the second mounting portion to form a gap between the first mounting portion and the second mounting portion, thereby spaced apart.

Therefore, when water adheres to the positive and negative terminals, because the first and second mounting portions are spaced apart, the water adhering to the positive and negative terminals is not communicating. When the charging interface is charging, the positive and negative terminals will not short-circuit due to water adhering to their surfaces, thus improving the safety performance of the charging interface and expanding the application scenarios of the wearable device.

[0039] The following description provides specific application scenarios and requirements for this specification, intended to enable those skilled in the art to make and use the contents of this specification. Various partial modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principles defined herein can 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 rather to the widest scope consistent with the claims.

[0040] The terminology used herein is for the purpose of describing particular exemplary embodiments only and is not restrictive. For example, unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” used herein may also include the plural forms. When used in this specification, the terms “comprising,” “including,” and / or “containing” mean that the associated integers, steps, operations, elements, and / or components are present, but do not exclude the presence of one or more other features, integers, steps, operations, elements, components, and / or groups, or that other features, integers, steps, operations, elements, components, and / or groups may be added to the system / method.

[0041] 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. That is, X can include any combination of A, B, and C, or any combination of A, B, and C, as well as other possible content / elements. The arbitrary combination of A, B, and C can be A, B, C, AB, AC, BC, or ABC.

[0042] In this application, unless explicitly stated otherwise, the relationships between structures can be direct or indirect. For example, when describing "A is connected to B," unless it is explicitly stated that A and B are directly connected, it should be understood that A can be directly connected to B or indirectly connected to B. Similarly, when describing "A is above B," unless it is explicitly stated that A is directly above B (AB is 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.

[0043] Considering the following description, these and other features of this specification, as well as the operation and function of related structural elements, and the economy of assembly and manufacture of components, can be significantly improved. This description also includes all figures and text in the accompanying drawings, all of which form part of this specification. However, it should be clearly understood that the drawings are for illustrative and descriptive 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.

[0044] The wearable device provided in this application is a waterproof wearable device. The wearable device provides a certain degree of waterproofing, allowing it to be used in specific scenarios to prevent water from entering the device from the outside, such as during rain, swimming, or brief submersion. The wearable device may include AR / VR / MR headsets, smart audio glasses, Bluetooth headphones, wearable speakers, smartwatches, smart bracelets, smart rings, smart clothing, smart sneakers, etc. For ease of demonstration, the following description uses waterproof headphones as an example. It should be noted that those skilled in the art should understand that wearable devices are also within the scope of protection of this specification.

[0045] The waterproof headphones can be of any form. For example, they can be wired. The receiver in a wired waterproof headphone can receive electrical signals from a media player via wired transmission, thus converting the electrical signals into sound waves audible to the human ear. Alternatively, they can be wireless. The receiver in a wireless waterproof headphone can receive electrical signals from a media player via wireless transmission, thus converting the electrical signals into sound waves audible to the human ear. They can also be air-conduction waterproof headphones. Air-conduction waterproof headphones can convert electrical signals into air vibration signals. These air vibration signals can be transmitted to the ear canal. The eardrum in the ear can convert these air vibration signals into sound. Furthermore, they can be bone-conduction waterproof headphones. Bone-conduction waterproof headphones can convert electrical signals into mechanical vibration signals. These mechanical vibration signals can cause vibrations in the skull, causing the perilymph to oscillate at the same frequency, and stimulating the spiral organ in the cochlea to produce hearing. It should be noted that the waterproof headphones provided in this application include a data storage unit. At this point, the waterproof headphones can play audio data stored in the built-in data storage unit without relying on an external media player, even when not transmitting signals with an external media player. This specification does not limit the type of waterproof headphones.

[0046] As mentioned above, the wearable device is a waterproof headset. Figure 1 An exploded structural diagram of a waterproof earphone 001 provided according to some exemplary embodiments of this application is shown. Figure 1 As shown, the waterproof earphone 001 may include a mechanism assembly 100 and a main body 300. In some embodiments, the waterproof earphone 001 may also include a back-hook assembly 500.

[0047] The mechanism assembly 100 can also be called a speaker assembly. The mechanism assembly 100 converts electrical signals into sound waves that can be heard by humans. The number of mechanism assemblies 100 can be one or two. When there is only one mechanism assembly 100, the waterproof earphone 001 can be used in applications where stereo sound requirements are not particularly high, such as hearing aids for hearing-impaired patients or prompting for live broadcasts. When a user wears the waterproof earphone 001, the mechanism assembly 100 can be worn in either the user's left or right ear. When there are two mechanism assemblies 100, the two mechanism assemblies 100 are worn in different ears. In this case, both mechanism assemblies 100 can produce sound, thus giving the waterproof earphone 001 a stereo sound effect and improving user experience. In some embodiments, the two mechanism assemblies 100 can be set independently. That is, the two mechanism assemblies 100 can exist independently and can be worn separately. For example, the two mechanism components 100 can be worn on different ears or on the ears of different users, making the waterproof headphones 001 more flexible in use. In this case, the two mechanism components 100 can operate independently. In some embodiments, the two mechanism components 100 can also be connected together (e.g., via a rear-hook component 500). In this case, the two mechanism components 100 can operate simultaneously and can be uniformly controlled to obtain better sound effects. In some embodiments, the mechanism component 100 can be an air conduction mechanism. In this case, when the user wears the waterproof headphones 001, the mechanism component 100 can be in-ear or open-ear. In some embodiments, the mechanism component 100 can also be a bone conduction mechanism. In this case, when the user wears the waterproof headphones 001, the mechanism component 100 can be attached to the outside of the user's ear. For example, the mechanism component 100 can be attached to the outside of the ear and close to the skin to transmit sound waves to the inside of the ear through vibrations of the skin and bones. In some embodiments, the mechanism component 100 can be a combination of an air conduction mechanism and a bone conduction mechanism.

[0048] The main body 300 can be electrically connected to the mechanism assembly 100 to control the mechanism assembly 100. In the waterproof earphone 001, the main body 300 can be the ear hook assembly of the waterproof earphone 001. In some embodiments, the main body 300 can receive electrical signals sent by an external media player and send the electrical signals to the mechanism assembly 100. The main body 300 can have a built-in data storage unit. At this time, the main body 300 can send the audio data from the built-in data storage unit to the mechanism assembly 100. The number of main bodies 300 can be one or more. In some embodiments, each mechanism assembly 100 can be connected to one main body 300. In some embodiments, the waterproof wearable device is a waterproof earphone 001, and the waterproof earphone 001 can consist of two mechanism assemblies 100, wherein the two mechanism assemblies 100 can share one main body 300. When the waterproof earphone 001 includes two mechanism assemblies 100 and two main bodies 300, the two mechanism assemblies 100 are electrically connected to the two main bodies 300 respectively. At this time, the two main bodies 300 can be set independently to independently control the mechanism assembly 100. The two main bodies 300 can also be connected together, for example, by connecting the two main bodies 300 through a cable assembly 500, so as to achieve unified control of the two mechanism assemblies 100.

[0049] like Figure 1 As shown, the main body 300 includes a housing 320, electronic components 340, and a charging interface 380. In some embodiments, the main body 300 may also include control buttons 360.

[0050] The housing 320 can serve as a mounting base for electronic component 340. The housing 320 can be a hollow, thin-walled shell structure. Electronic component 340 can be installed inside the housing 320. The shape of the housing 320 can be arbitrary to accommodate the installation of other components. The shape of the housing 320 can be ergonomic to facilitate user operation. The material of the housing 320 can be any material, such as metal, plastic, polymer, etc. This manual does not limit the shape or material of the housing 320.

[0051] In some embodiments, the housing 320 may be integrally formed. In some embodiments, the housing 320 may include at least two housings. For example, the housing 320 may include two housings, namely a main housing 321 and a housing cover 323. The main housing 321 and the housing cover 323 are installed together to form an internally hollow housing structure. In some embodiments, the housing 320 may also be composed of more than two housings installed together, which will not be elaborated in this specification. The main housing 321 and the housing cover 323 are thin-walled parts. The main housing 321 and the housing cover 323 can be installed together to form a receiving compartment inside. The receiving compartment allows for the accommodation of other components and allows other components to be installed in the receiving compartment, thereby protecting and dustproofing other components. For example, electronic component 340 can be installed inside the housing 320, for example, inside the receiving compartment. The connection between the main housing 321 and the housing cover 323 can be sealed with sealant to improve the waterproof performance of the housing 320.

[0052] Electronic component 340 may include a circuit board. The mechanism assembly 100 may be electrically connected to the circuit board. The mechanism assembly 100 and the circuit board are electrically connected via a cable assembly 500. The circuit board can control the mechanism assembly 100. The circuit board is a chip integrated circuit integrating waterproof headphone functionality. In some embodiments, the circuit board includes a radio frequency unit for receiving and transmitting signals, such as Bluetooth, NFC, Wi-Fi, or other communication elements, to enable communication with an external media player. The circuit board also includes a data storage unit for storing audio data. In some embodiments, the circuit board further 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 networking, etc. 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 can be any circuit or processor capable of performing one or more functions, or any combination thereof.

[0053] 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 a circuit board. Users can operate the control button 360 to control the circuit board, enabling the waterproof earphone 001 to perform functions such as turning it on / off, adjusting volume, and switching modes, thereby enhancing the intelligence of the waterproof earphone 001 and improving the user experience.

[0054] The main body 300 also includes a charging interface 380. When the waterproof earphone 001 comprises two main bodies 300, the charging interface 380 can be located in either main body 300 and electrically connected to the electronic component 340. The charging interface 380 can be mounted on the housing 320 and partially exposed outside the housing 320 for electrical connection with the charging plug (which will be described later). The charging interface 380 can be electrically connected to the electronic component 340 to provide power to the electronic component 340. The power can be transferred through the electronic component 340 to other components, such as the mechanism assembly 100. The fixing connection between the charging interface 380 and the housing 320 can be any form, including but not limited to adhesive, riveting, welding, threaded connection, snap-fit ​​connection, etc. The connection between the housing 320 and the charging interface 380 can also be sealed with sealant to improve the waterproof performance of the waterproof earphone 001.

[0055] In some embodiments, the waterproof earphone 001 may further include a back-hook assembly 500. The back-hook assembly 500 can connect two mechanism assemblies 100. For example, when the two mechanism assemblies 100 are electrically connected to two bodies 300 respectively, the back-hook assembly 500 can electrically connect the two bodies 300. Alternatively, when the two mechanism assemblies 100 share a single body 300, the body 300 can be close to either of the two mechanism assemblies 100, and the back-hook assembly 500 can electrically connect the body 300 to the other of the two mechanism assemblies 100.

[0056] In some embodiments, the rear-mounted component 500 may include a cable. The cable can be any conductive material, such as a conductor. The cable is primarily used to achieve electrical connections between the various electronic components of the waterproof earphone 001. For example, when two mechanism components 100 are electrically connected to two main bodies 300 respectively, the cable can electrically connect the two main bodies 300. Alternatively, when two mechanism components 100 share a single main body 300, the main body 300 can be close to either of the two mechanism components 100, and the cable can electrically connect the main body 300 to the other mechanism component 100. The cable can be one or more strands. When there are multiple circuits requiring electrical connections in the waterproof earphone 001, the cable can be configured with multiple strands accordingly; for example, the cable can be configured with any number of strands, such as 1, 2, 3, 5, 6, or 8 strands.

[0057] In some embodiments, the back-hook assembly 500 may also include an elastic metal wire. The elastic metal wire may have an arc-shaped design to provide a certain clamping force when the user wears the waterproof headphones. 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. In this case, when the user wears the waterproof headphones 001, the two main bodies 300 can be hung on the outside of the user's ears, and the back-hook assembly 500 is used to wrap around the back of the user's head, with the two core components 100 located near the two ears respectively. At this time, the elastic metal wire can provide a certain clamping force, allowing the two core components 100 to fit snugly against the user's skin, thereby improving wearing reliability.

[0058] In some embodiments, the waterproof earphone 001 may further include a protective cover 600. The protective cover 600 may cover the outer surface of the mechanism assembly 100. The protective cover 600 may also cover the outer surface of the main body 300. The protective cover 600 may also cover the outer surface of the rear-hook assembly 500. The protective cover 600 may be integrally molded or may be composed of multiple protective covers joined together. The protective cover 600 may be sealed to the mechanism assembly 100, the main body 300, and the rear-hook assembly 500 using sealant to improve the waterproof performance of the waterproof earphone 001. The protective cover 600 may be made of a soft material with a certain degree of elasticity, such as soft silicone or rubber.

[0059] It should be noted that the connection between the mechanism assembly 100 and the main body 300 can also be sealed with sealant to improve the waterproof performance of the waterproof earphone 001. Similarly, the connection between the main body 300 and the rear-mount assembly 500 can also be sealed with sealant to improve the waterproof performance of the waterproof earphone 001.

[0060] Figure 2 This illustration shows a front view of a charging interface 380 provided according to some exemplary embodiments of this application; Figure 3 It shows Figure 2 Sectional view AA; Figure 4 A bottom view of a charging interface 380 provided according to some exemplary embodiments of this application is shown; Figure 5 A rear view of a charging interface 380 provided according to some exemplary embodiments of this application is shown. Figures 2 to 5 As shown, the charging interface 380 includes a charging female connector 382, ​​a charging terminal 384, and a data transmission terminal 386. In some embodiments, the charging interface 380 may further include an adapter plate 387. In some embodiments, the charging interface 380 may further include a magnetic device 388.

[0061] The charging female connector 382 can serve as the base for the charging interface 380. Other components of the charging interface 380 (such as the charging terminal 384, data transmission terminal 386, adapter plate 387, and magnetic device 388) can use the charging female connector 382 as a base and be mounted on it. The charging female connector 382 is mounted on the housing 320 of the main body 300. To improve the waterproof performance of the waterproof earphone 001, the charging female connector 382 and the waterproof earphone 001 can be sealed together with sealant. One side of the charging female connector 382 can be exposed outside the housing 320 for connection with an external charging plug. The other side of the charging female connector 382 can face the inside of the housing 320 or extend into the housing 320. The charging female connector 382 can be a thin-walled, plate-like structure, which can be integrally molded or molded separately and then assembled, with each part sealed and bonded together with sealant during assembly. The shape of the charging female connector 382 can be arbitrary to accommodate the installation of other components. The base material of the charging female connector 382 can be an insulating material, such as plastic, polymer material, resin, etc., and the shape can be rectangular, circular or other irregular shapes.

[0062] Charging terminal 384 is mounted on charging socket 382. Specifically, charging socket 382 has a hole through which charging terminal 384 passes, with one end of charging terminal 384 located on one side of the hole and the other end on the other side. The contact portion of charging terminal 384 is sealed to the hole with sealant. Charging terminal 382 can be electrically connected to electronic component 340. Specifically, charging terminal 382 can be electrically connected to electronic component 340 to supply power to electronic component 340. When charging interface 380 is connected to an external charging plug for charging, charging terminal 384 can be electrically connected to the power source of the charging plug. Charging terminal 384 may include a positive terminal 3841 and a negative terminal 3843. Positive terminal 3841 and negative terminal 3843 are at least partially exposed outside of charging socket 382. When charging interface 380 is connected to an external charging plug for charging, 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 terminal of the external power supply. The positive terminal 3841 and the negative terminal 3843 are spaced apart to prevent short circuits between the positive and negative terminals. In the scenario where the user is swimming, although most of the water on the charging port 380 is cleaned off after swimming, a small amount of water still remains attached to the positive terminal 3841 and the negative terminal 3843. Specifically, when the user holds the backrest assembly 500 and forcefully shakes off the water attached to the waterproof earphone 001, the backrest assembly 500 will rotate around the wrist. At this time, the water accumulated in the charging port 380 will be subjected to centrifugal force. A large amount of water experiences a centrifugal force greater than the adhesion between the water and the charging port 380 and detaches from the charging port 380, while a small amount of water experiences a centrifugal force less than the adhesion between the water and the charging port 380 and remains on the surface of the charging port 380. This water remaining on the surface of the charging port 380 easily connects the positive terminal 3841 and the negative terminal 3843. To prevent water adhering to the positive terminal 3841 and the negative terminal 3843 from causing a short circuit 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 adhering to the positive terminal 3841 and the negative terminal 3843 cannot be connected.

[0063] Data transmission terminal 386 can be mounted on charging connector 382. Data transmission terminal 386 can be electrically connected to electronic component 340. For example, data transmission terminal 386 can be electrically connected to data storage unit on circuit board to perform data transmission with data storage unit. Data transmission terminal 386 may include first terminal 3861 and second terminal 3863. When charging interface 380 is connected to charging plug, data transmission terminal 386 can communicate with electronic device connected to charging plug to realize data transmission between electronic device and storage unit.

[0064] It should be noted that the charging terminal 384 and the data transmission terminal 386 can perform their respective functions individually or jointly. Specifically, the charging terminal 384 and the data transmission terminal 386 can perform the charging function and the data transmission function respectively; 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.

[0065] In some embodiments, the charging interface 380 further includes an adapter plate 387. The adapter plate 387 may 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 may be sealingly connected to the charging socket 382 to prevent water from entering the wearable device (e.g., the interior of the housing 320) through the charging socket 382 from the outside. The adapter plate 387 may be sealingly connected to the charging socket 382 using sealant.

[0066] As previously described, charging terminal 384 and data transmission terminal 386 can be electrically connected to electronic component 340. Specifically, charging terminal 384 and data transmission terminal 386 can be electrically connected to electronic component 340 via cables. To ensure the sealing between adapter plate 387 and charging socket 382, ​​charging terminal 384 and data transmission terminal 386 can be soldered to the cables on adapter plate 387. The surface of adapter plate 387 facing the inside of housing 320 is covered with sealant to seal the solder joints of charging terminal 384 and data transmission terminal 386 to the cables.

[0067] 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 inside of the wearable device (e.g., inside the housing 320). The charging plug is equipped 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 securing the charging interface 380 and the charging plug together. The connection between the charging interface 380 and the charging plug via the adsorption device and the magnetic device 388 not only fixes the charging interface 380 to the charging plug, but also allows for quick alignment of the charging interface 380 and the charging plug through the corresponding positions of the adsorption device and the magnetic device 388, achieving accurate connection and increasing connection reliability and ease of operation. The adsorption device and the magnetic device 388 can be two magnets that attract each other. It should be noted that the magnetic device 388 can be located on the charging plug, and the adsorption device can be located on the charging interface 380; this is not limited.

[0068] The magnetic device 388 can be located anywhere on the charging interface 380, such as on the charging socket 382. Furthermore, the magnetic device 388 can be located anywhere on the charging socket 382, ​​such as between the charging terminal 384 and the data transmission terminal 386, or between the positive terminal 3841 and the negative terminal 3843.

[0069] like Figures 2 to 5 As shown, the charging female connector 382 includes a charging female connector base 3825, a first mounting portion 3821, a second mounting portion 3822, and a third mounting portion 3823. In some embodiments, the charging female connector base 3825, the first mounting portion 3821, the second mounting portion 3822, and the third mounting portion 3823 are an integral unit, i.e., integrally formed. In some embodiments, the charging female connector base 3825, the first mounting portion 3821, the second mounting portion 3822, and the third mounting portion 3823 are separate units but fixedly connected together. The fixed connection methods include, but are not limited to, bonding, welding, riveting, threaded connection, etc. Figures 2 to 5 In the illustrated embodiment, the charging female base 3825, the first mounting part 3821, the second mounting part 3822, and the third mounting part 3823 are integrally formed.

[0070] As previously mentioned, the charging female connector 382 can be installed on the housing 320. Specifically, the charging female connector 382 can be installed on the housing 320 via a charging female connector base 3825. The charging female connector base 3825 and the housing 320 are sealed together with sealant. The charging female connector 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 exterior of the wearable device (e.g., waterproof earphone 001), and the second side 3825-2 faces the interior of the wearable device (e.g., waterproof earphone 001). When the charging interface 380 is connected to a third-party charging plug, the third-party charging plug connects to the charging interface 380 from the first side 3825-1.

[0071] In some embodiments, the charging female base 3825 further includes a sidewall 3825-5. The sidewall 3825-5 is located at the edge of the charging female base 3825 and protrudes from the first side 3825-1 of the charging female base 3825 in a direction away from the charging female base 3825 to form a positioning groove for positioning when connected to a charging plug. The sidewall 3825-5 may be located at the edge of the charging female base 3825 and form a closed groove along the edge. When the charging female base 3825 is installed with the housing 320, the outer side of the sidewall 3825-5 can be used for installation with the housing 320 and sealed with sealant.

[0072] As previously described, the adapter plate 387 can be sealingly connected to the side of the charging female connector 382 facing the interior of the wearable device. Specifically, the adapter plate 387 can be sealingly connected to the second side 3825-2 of the charging female connector base 3825. For example, the second side 3825-2 of the charging female connector base 3825 can have a protrusion extending away from the second side 3825-2. The adapter plate 387 can be sealingly connected to the protrusion to seal the charging terminal 384 and the data transmission terminal 386 within the space formed by the protrusion and the adapter plate 387. As previously described, the magnetic device 388 can be installed on the side of the charging female connector 382 facing the interior of the wearable device (e.g., inside the housing 320). Specifically, the magnetic device 388 can be installed on the second side 3825-2 of the charging female connector base 3825. For example, the magnetic device 388 can be installed around the protrusion.

[0073] 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 female base 3825 and 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 has a mounting hole. The positive terminal 3841 can be fixedly mounted on the mounting hole on the first mounting portion 3821, and the positive terminal 3841 is at least partially exposed outside the first mounting portion 3821 for electrical connection with the charging plug. The fixing methods of the positive terminal 3841 and the first mounting portion 3821 include, but are not limited to, bonding, snap-fitting, welding, and interference fit. To improve the waterproof performance of the charging interface 380, 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 has a mounting hole. The negative terminal 3843 can be fixedly mounted on the mounting hole on the second mounting portion 3822, and the negative terminal 3843 is at least partially exposed outside the second mounting portion 3822 for electrical connection with the charging plug. The fixing methods between the negative terminal 3843 and the second mounting portion 3822 include, but are not limited to, bonding, snap-fitting, welding, and interference fit. To improve the waterproof performance of the charging interface 380, sealant can be filled between the negative terminal 3843 and the mounting hole of 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 has mounting holes. The data transmission terminal 386 can be fixedly mounted on the mounting hole on the third mounting portion 3823, and the data transmission terminal 386 is at least partially exposed outside the third mounting portion 3823 for electrical connection with the charging plug. The fixing methods between the data transmission terminal 386 and the third mounting portion 3823 include, but are not limited to, bonding, snap-fitting, welding, and interference fit. To improve the waterproof performance of the charging interface 380, sealant can be filled between the data transmission terminal 386 and the mounting hole of the third mounting portion 3823 to form a sealed connection. As mentioned above, the data transmission terminal 386 includes a first terminal 3861 and a second terminal 3863. Correspondingly, the third mounting portion 3823 may be provided with two mounting holes for mounting the first terminal 3861 and the second terminal 3863, respectively.

[0074] As mentioned earlier, to prevent water adhering to the positive and negative terminals 3841 and 3843 from causing a short circuit during charging, the positive and negative terminals 3841 and 3843 need to be spaced apart to prevent the water adhering to them from communicating. Therefore, the first mounting part 3821 and the second mounting part 3822 are spaced apart to prevent the water adhering to the surface of the first mounting part 3821 facing the charging plug and the water adhering to the surface of the second mounting part 3822 facing the third-party charging plug from communicating. 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 the water adhering to the surface of the first mounting portion 3821 facing the charging plug and the water adhering to the surface of the second mounting portion 3822 facing the third-party charging plug are not in communication, the water adhering to the portion of the positive terminal 3841 exposed outside the first mounting portion 3821 and the water adhering to the portion of the negative terminal 3843 exposed outside the second mounting portion 3822 are also not in communication.

[0075] The spacing between the first mounting portion 3821 and the second mounting portion 3822 can be achieved in various 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. Figures 2 to 5 In the illustrated embodiment, 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.

[0076] like Figures 2 to 5 As shown, 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 causing 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 protrude. 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 protrude. Yet another example is that both the first mounting portion 3821 and the second mounting portion 3822 protrude in a direction away from the first side 3825-1.

[0077] When both the first mounting portion 3821 and the second mounting portion 3822 protrude away from the first side 3825-1, the heights of the protrusions of the first mounting portion 3821 and the second mounting portion 3822 can be the same or different. When the charging female base 3825 includes a side wall 3825-5 and the heights of the protrusions of the first mounting portion 3821 and the second mounting portion 3822 are the same, the heights of the protrusions of the first mounting portion 3821 and the second mounting portion 3822 can be higher than the height of the side wall 3825-5, or the heights of the protrusions of the first mounting portion 3821 and the second mounting portion 3822 can be equal to or lower than the height of the side wall 3825-5. In the scenario described above, after the user swims ashore, a large amount of water on the charging port 380 is cleaned off, but a small amount of water remains attached to the first mounting portion 3821 and the second mounting portion 3822. The relationship between the heights of the protrusions of the first mounting portion 3821 and the second mounting portion 3822 and the height of the side wall 3825-5 can be arbitrary, such as higher than, lower than, or equal to. At this time, the water stains on the surfaces of the first mounting part 3821 and the second mounting part 3822 facing the charging plug cannot communicate, and the positive terminal 3841 and the negative terminal 3843 installed on the first mounting part 3821 and the second mounting part 3822 will not communicate to form a short circuit during charging. In some scenarios, a large amount of water accumulates and gathers in the charging female base 3825, potentially flooding the surfaces of the first mounting part 3821 and the second mounting part 3822 facing the charging plug simultaneously. In this case, the height of the protrusions of the first mounting part 3821 and the second mounting part 3822 is higher than the height of the side wall 3825-5. When water enters and accumulates in the charging female base 3825, the surfaces of the first mounting part 3821 facing the charging plug and the second mounting part 3822 facing the charging plug will not be submerged by water. That is, the water stains in the side wall 3825-5 cannot be connected. During charging, the positive terminal 3841 and the negative terminal 3843 installed on the first mounting part 3821 and the second mounting part 3822 will not be connected to form a short circuit.

[0078] When the charging female base 3825 includes a side wall 3825-5, and the heights of the protrusions of the first mounting portion 3821 and the second mounting portion 3822 are not the same, the protrusion height of the one with the higher height of the first mounting portion 3821 and the second mounting portion 3822 is greater than the height of the side wall 3825-5. In this case, when water enters and accumulates inside the charging female base 3825, the surfaces of the first mounting portion 3821 and the second mounting portion 3822 facing the charging plug will not be simultaneously submerged. During charging, the positive terminal 3841 and the negative terminal 3843 mounted on the first mounting portion 3821 and the second mounting portion 3822 will not connect to form a short circuit.

[0079] 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, the size of the gap 3828 between the first mounting portion 3821 and the second mounting portion 3822 should be as large as possible within the allowable dimensional range. A larger gap 3828 allows for a greater volume of water to be contained within it, making it less likely for 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 to communicate. In some embodiments, the size of the gap 3828 is related to the material of the first mounting portion 3821 and the second mounting portion 3822. For example, the materials of the first mounting portion 3821 and the second mounting portion 3822 may be hydrophobic materials, such as polyolefin, polycarbonate, polyamide, polyacrylonitrile, polyester, fluorinated polyethylene, fluorocarbon wax, etc. Furthermore, the roughness of the surfaces of the first mounting portion 3821 and the second mounting portion 3822 facing the charging plug should be as small as possible within acceptable limits, so as to form a glossy surface on the surfaces of the first mounting portion 3821 and the second mounting portion 3822 facing the charging plug, thereby increasing hydrophobicity. Further, the surfaces of the first mounting portion 3821 and the second mounting portion 3822 facing the charging plug can be nano-treated to further increase hydrophobicity.

[0080] In some embodiments, hydrophobicity can be measured using a contact angle measurement method. Further, the contact angle can be calculated based on the Young-Laplace equation and the concept of surface tension. Specifically, the surface energy of a water droplet on the surface of the first mounting part 3821 facing the charging plug and the surface of the second mounting part 3822 facing the charging plug can be measured, and the contact angle can be calculated according to the Young-Laplace equation. Alternatively, the contact angle can be measured directly. Specifically, after cleaning and drying the surfaces of the first mounting part 3821 and the second mounting part 3822 facing the charging plug to ensure there are no impurities or dirt, a drop of water is carefully placed on the surface using a dropper or syringe. The shape of the droplet on the surface is recorded using a microscope or camera, and the angle between the water droplet and the contact line with the surface is measured. The measured angle is the contact angle of the water droplet.

[0081] A large contact angle between a water droplet and a surface indicates good hydrophobicity, meaning the water droplet is difficult to spread on the surface. For example, if a 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. Similarly, if a water droplet forms a large contact angle on the surface of the second mounting portion 3822, it indicates that the second mounting portion 3822 has good hydrophobicity. Furthermore, if a 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. The contact angle of the water droplet is at least 60°, for example, 60°, 70°, 80°, 90°, 100°, etc. Those skilled in the art should understand that other methods of measuring contact angles are also within the scope of this specification.

[0082] It should be noted that the above-mentioned range of contact angle values ​​and measurement methods apply to any structure in this specification with water droplets adhering to its surface, such as the third mounting part 3823, the gap 3828, the sidewall 3825-5, etc. Specifically, the contact angle of the surface of the first mounting part 3821 is at least 60° and / or the contact angle of the surface of the second mounting part 3822 is at least 60° and / or the contact angle of the surface of the gap 3828 is at least 60°. That is, the contact angles of the surfaces of the first mounting part 3821, the second mounting part 3822, and the gap 3828 can all simultaneously satisfy at least 60°, or they can each satisfy at least 60°. When at least one of the contact angles of the surfaces of the first mounting part 3821, the second mounting part 3822, and the gap 3828 satisfies at least 60°, the water stains on the first mounting part surface and the second mounting part surface will not connect, thus avoiding a short circuit.

[0083] The more easily water adheres to the materials of the first mounting portion 3821 and the second mounting portion 3822, the larger the size of the gap 3828. In some embodiments, to ensure that the water adhering to the surface of the first mounting portion 3821 facing the charging plug and the water adhering to the surface of the second mounting portion 3822 facing the charging plug are not in communication, the depth of the gap 3828 is greater than 0.6 mm, and the width of the gap 3828 is greater than 0.6 mm. The width direction of the gap 3828 can be the direction in which the first mounting portion 3821 and the second mounting portion 3822 are arranged. The depth direction of the gap 3828 can be the direction in which the first mounting portion 3821 and the second mounting portion 3822 protrude.

[0084] In some embodiments, to increase the width of the gap 3828, the first mounting portion 3821 and the second mounting portion 3822 may be arranged in the length direction of the charging female base 3825 to increase the distance between the positive terminal 3841 and the negative terminal 3843. Additionally, to further increase the width of the gap 3828, a third mounting portion 3823 may be disposed between the first mounting portion 3821 and the second mounting portion 3822 to act as a separator between them. In some embodiments, the first terminal 3861 and the second terminal 3863 may be arranged in the width direction of the charging female base 3825 to reduce the overall size of the charging female base 382.

[0085] In some embodiments, to reduce processing difficulty and improve ease of use, the third mounting portion 3823 may be integrally connected with 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 is the same as the height of the first mounting portion 3821 or the second mounting portion 3822 connected to it.

[0086] This application also provides a charging plug that connects to the charging interface 380 during operation. The charging interface 380 connects to external power supply devices and / or data transmission devices via the charging plug. Figure 6 This illustration shows a front view of a charging plug 600 provided according to some exemplary embodiments of this application; Figure 7 It shows Figure 6 BB (sectional view); Figure 8 A cross-sectional view is shown showing a charging interface 380 connected to a charging plug 600 according to some exemplary embodiments of this application. For example... Figures 6 to 8 As shown, 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 further includes a charging circuit board assembly 670. In some embodiments, the charging plug also includes a transmission interface 680. In some embodiments, the charging plug 600 further includes an adsorption device 690.

[0087] The charging probe 640 includes a positive probe 641 and a negative probe 643. When the charging interface 380 is connected to the charging plug 600, the positive terminal 3841 contacts the positive probe 641 to achieve electrical connection. The negative terminal 3843 contacts the negative probe 643 to achieve electrical connection. The positive probe 641 and the negative probe 643 can be flexible probes to ensure reliable contact between the positive terminals 3841 and 641, and between the negative terminals 3843 and 643, when the charging interface 380 is connected to the charging plug 600.

[0088] 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 probe 661 and the second probe 663 can be flexible probes to ensure 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.

[0089] The charging case 620 can serve as a mounting base for the charging probe 640 and the data transmission probe 660. The charging case 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 case 620. The shape of the charging case 620 can be arbitrary to accommodate the installation of other components. The base material of the charging case 620 can be an insulating material, such as plastic, polymer material, resin, etc., and its shape can be rectangular. The shape of the charging case 620 can be adapted to the shape of the charging socket 382.

[0090] The charging case 620 includes a charging case base 625, a fourth mounting part 621, a fifth mounting part 622, and a sixth mounting part 623. The charging case base 625 can serve as a carrier for the other components, such as the charging probe 640, the data transmission probe 660, the fourth mounting part 621, the fifth mounting part 622, and the sixth mounting part 623.

[0091] The fourth mounting portion 621, the fifth mounting portion 622, and the sixth mounting portion 623 are connected to the externally facing side (charging interface 380) of the charging compartment base 625. 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 electrode probe 641 can be mounted on the fourth mounting portion 621. The negative electrode 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. 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.

[0092] 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 ensuring that water adhering to the surfaces of the first mounting portion 3821 and the second mounting portion 3822 is not connected, thereby ensuring that the positive terminal 3841 and the negative terminal 3843 do not form a short circuit during charging. The baffle 624 may be made of an insulating material.

[0093] In some embodiments, the charging plug 600 further includes a charging circuit board assembly 670. The charging circuit board assembly 670 is mounted on the charging compartment 620 and electrically connected to the charging probe 640 and the data transmission probe 660.

[0094] 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.

[0095] 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.

[0096] As mentioned above, the spacing between the first mounting part 3821 and the second mounting part 3822 can also be achieved in other ways, such as by setting an insulating barrier between the first mounting part 3821 and the second mounting part 3822. Figure 9 A cross-sectional view of another charging interface 380 provided according to some exemplary embodiments of this application is shown. For ease of description, we will... Figure 9 The charging interface shown is defined as charging interface 380a. For example... Figure 9 As shown, an insulating plate 3829 can be provided between the first mounting portion 3821 and the second mounting portion 3822 in the charging interface 380a.

[0097] The charging female connector 382 also includes an insulating plate 3829. The insulating plate 3829 is located 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 mounting portion 3821 and the second mounting portion 3822, such that the first mounting portion 3821 and the second mounting portion 3822 are spaced apart. At this time, water adhering to the surface of the first mounting portion 3821 facing the charging plug will not communicate with water adhering to the surface of the second mounting portion 3822 facing the charging plug, and the positive terminal 3841 and the negative terminal 3843 mounted on the first mounting portion 3821 and the second mounting portion 3822 will not communicate, thereby preventing a short circuit when the charging connector 380a is connected to the charging plug.

[0098] 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 set away from the rear mounting assembly 500 to drain water, thereby preventing a short circuit when the charging connector 380a is connected to the charging plug.

[0099] 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, the size of the insulating plate 3829 between the first mounting portion 3821 and the second mounting portion 3822 should be as large as possible within the allowable size range. The larger the size of the insulating plate 3829, the less likely 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. In some embodiments, the size of the insulating plate 3829 is related to the material of the first mounting portion 3821 and the second mounting portion 3822. The larger the size of the insulating plate 3829, the more easily water adheres to the material of the first mounting portion 3821 and the second mounting portion 3822. In some embodiments, to ensure 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 do not communicate, the height of the protrusion of the insulating plate 3829 relative to the first mounting portion 3821 and the second mounting portion 3822 is greater than 0.6 mm. In some embodiments, the thickness of the insulating plate 3829 is greater than 0.6 mm.

[0100] To further improve waterproof performance, the insulating board 3829 can be made of a hydrophobic material. Furthermore, the contact angle of water droplets adhering to the insulating board 3829 is at least 60°, for example, 60°, 70°, 80°, 90°, 100°, etc. The method for measuring the contact angle of water droplets adhering to the insulating board 3829 is consistent with the aforementioned method and will not be repeated here. Those skilled in the art should understand that other methods for measuring contact angles are also within the scope of this specification.

[0101] Specifically, 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°. That is, the contact angles of the surfaces of the first mounting portion 3821, the second mounting portion 3822, and the insulating plate 3829 can all simultaneously satisfy at least 60°, or they can each satisfy at least 60°. When at least one of the contact angles of the surfaces of the first mounting portion 3821, the second mounting portion 3822, and the insulating plate 3829 satisfies at least 60°, water stains on the surface of the first mounting portion 3821 and the second mounting portion 3822 will not connect, thus preventing a short circuit.

[0102] It should be noted that, in order to match the charging interface 380a, a groove is provided between the fourth mounting portion 621 and the fifth mounting portion 622. When the charging interface 380a is connected to the charging plug, the insulating plate 3829 is located in the groove. The insulating plate 3829 matches the groove, which can be used for positioning the charging interface 380a when connected to the charging plug. Matching can mean that the shape and size of the mating surface of the insulating plate 3829 and the groove match. When the insulating plate 3829 mates with the groove, the insulating plate 3829 is engaged in the groove.

[0103] In some embodiments, the spacing between the first mounting portion 3821 and the second mounting portion 3822 can be achieved by disposing a third mounting portion 3823 between the first mounting portion 3821 and the second mounting portion 3822. Figure 10 A cross-sectional view of another charging interface 380 provided according to some exemplary embodiments of this application is shown. For ease of description, we will... Figure 10 The charging interface shown is defined as charging interface 380b. For example... Figure 10 As shown, 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 away from the first side 3825-1 relative to the first mounting portion 3821 and the second mounting portion 3822, such that the first mounting portion 3821 and the second mounting portion 3822 are spaced apart 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 as described above and will not be repeated here.

[0104] Figure 11 A cross-sectional view of another charging interface 380 provided according to some exemplary embodiments of this application is shown. For ease of description, we will... Figure 10 The charging interface shown is defined as charging interface 380c. For example... Figure 11As shown, the third mounting portion 3823 is recessed relative to the first mounting portion 3821 and the second mounting portion 3822 towards the first side 3825-1, forming a gap 3828 between the first mounting portion 3821 and the second mounting portion 3822, thereby allowing the first mounting portion 3821 and the second mounting portion 3822 to be spaced apart. In this case, the recess at the third mounting portion 3823 can function as the aforementioned gap 3828. The principle for preventing short circuits is as described above and will not be repeated here.

[0105] The sealants used for the above-mentioned bonding include instant adhesives (such as 502 glue), epoxy resin adhesives, anaerobic adhesives, UV adhesives (ultraviolet light curing type), hot melt adhesives, pressure-sensitive adhesives, latex adhesives, silicone adhesives, etc.

[0106] In summary, this specification provides a charging interface 380 and a wearable device. By providing multiple mounting portions on the charging socket 382 of the charging interface 380, wherein the first mounting portion 3821 and the second mounting portion 3822 for mounting the positive terminal 3841 and the negative terminal 3843 of the charging terminal 384 are spaced apart, thereby preventing water adhering to the first mounting portion 3821 and the second mounting portion 3822 from communicating. Therefore, when water adheres to the positive terminal 3841 and the negative terminal 3843, because the first mounting portion 3821 and the second mounting portion 3822 are spaced apart, the water adhering to the positive terminal 3841 and the negative terminal 3843 is not communicating. When the charging port 380 is charging, the positive terminal 3841 and the negative terminal 3843 will not short-circuit due to water adhering to their surfaces, thereby improving the safety performance of the charging port 380 and expanding the application scenarios of wearable devices. This ensures that even if the wearable device is used underwater and the positive terminal 3841 and the negative terminal 3843 become wet, it will not cause a short circuit in the charging port 380 during charging. Furthermore, the charging port 380 and wearable device provided in this application enhance the user experience. After using the wearable device underwater, users do not need to wipe, clean, or dry the water in the charging port 380 before charging, greatly improving convenience.
