[0022] As an optional embodiment, the swimming goggles frame includes a frame, a waterproof rubber ring 11 arranged on one side of the frame, and a lens arranged between the frame and the waterproof rubber ring. In this embodiment, the waterproof rubber ring is made of silicone. In this embodiment, the frame is provided with a support frame / support, and the support frame is hung on the human face, especially the nose.

[0023] As an optional embodiment, the swimming goggle strap is a two-section structure, and a fixed adjustment buckle 5 is provided at the connection of the two-section structure, and the tightness of the swimming goggle strap is adjusted by adjusting the relative length between one section of the swimming goggle strap and the fixed adjustment buckle. Specifically, there are annular connection holes 4 at the ends of the swimming goggle frame body, and the ends of the swimming goggle strap are provided with a fixed adjustment buckle near the connection of the swimming goggle frame. The swimming goggle strap is connected to the swimming goggle frame as a whole by passing through the annular connection hole, and then the fixed adjustment buckle can be used to adjust the length of the swimming goggle strap according to the needs of the user.

[0024] As an optional implementation, the other swimming lens of the non-XR visualization lens is a common polycarbonate swimming lens. Both lenses are transparent, ensuring that the user can still clearly observe the environment outside the swimming goggles when wearing them.

[0025] In this embodiment, the connection relationship between the XR visualization lens and the main control module is a conventional application of the prior art. The XR visualization lens is connected to the optical waveguide module and the image source device in the goggle frame to jointly construct an XR display system, which works together to generate an XR display interface on the XR visualization lens.

[0026] The XR visualization lens is a full-color Micro LED micro display screen. The full-color Micro LED micro display screen cooperates with the optical waveguide module in the swimming goggle frame to realize the display of virtual scenes on the XR visualization lens. The optical waveguide technology uses the principle of waveguide to guide the image generated in the image source device through the optical waveguide, so that the image is transmitted inside the optical waveguide and finally projected onto the XR visualization lens for real-time observation by the user.

[0027] Example 2

[0028] On the basis of Example 1, in this embodiment, at least one monitoring sensor is disposed in the temple area on the inner side of the swimming goggle frame, and at least one monitoring sensor is attached to the occipital area on the rear side of the swimming goggle strap.

[0029] In this embodiment, the motion sensor in the occipital area is equipped with environmental sensing technology, which can monitor environmental parameters such as water temperature, water quality, and light. The two sensors collect data according to the best collection position of different parameters. For example, the temple area of ​​the head may be suitable for monitoring blood pressure, heart rate, blood oxygen saturation, body temperature, breathing and other index parameters, especially in the frontal and temporal areas; while the occipital area at the back of the head can be used to collect motion posture, speed, distance, water temperature, water quality and other motion and environmental index parameters.

[0033] In this embodiment, multiple sensors may be provided for monitoring, or only one or several items may be monitored through a specific sensor, or various sensors may be integrated into an integrated monitoring sensor to centrally monitor several items.

[0034] In this embodiment, a multifunctional motion sensor 8 is also attached to the back side of the goggle strap, i.e., the occipital region. The multifunctional motion sensor integrates an inertial measurement unit and environmental perception technology. Here, the left and right sides of the multifunctional motion sensor are connected in series with the goggle strap through an annular hole 7.

[0035] In this embodiment, two multifunctional motion sensors are attached to the user's skin surface to obtain accurate motion data of the user. The monitoring sensors used in this embodiment can all be common sensors on the market.

[0036] Example 3

[0037] On the basis of Example 1, a bone conduction audio device is provided on the goggle strap, and the bone conduction audio device 10 is electrically connected to the main control module. The bone conduction audio device is connected to the goggle strap through a sliding buckle, and the position of the bone conduction audio device is adjusted and fixed by adjusting the position of the sliding buckle 6 and the tightness of the goggle strap.

[0038] Specifically, the bone conduction audio device is attached to the side of the swimming goggle strap, that is, the protrusion of the temporal bone in front of the ear. The built-in bone conduction audio device is attached to the hollow structure inside the adjustable swimming goggle strap and is connected to the swimming goggle strap through a sliding buckle. The position of the bone conduction audio device can be adjusted and fixed by adjusting the position of the sliding buckle and the tightness of the swimming goggle strap. Users can adjust the position of the bone conduction audio device front and back according to different head shapes to provide a more comfortable wearing experience and improve audio clarity.

[0039] As an optional implementation, the data source of the bone conduction audio device is the same as that of the aforementioned XR display system, using data information from a lidar sensor and / or a multi-function motion sensor and / or a cloud platform to generate an audio signal that is transmitted to the bone conduction audio device for the user to listen to, thereby achieving auditory guidance.

[0040] Example 4

[0041] It also includes a laser radar sensor 2, which is arranged at the front end of the swimming goggle frame. The laser radar sensor is electrically connected to the main control module, and is used to detect the distance and speed between the user and the surrounding objects in real time.

[0042] Example 5

[0043] It also includes a positioning module, which is arranged inside the swimming goggles frame or integrated with the main control module, and is used to track the device through a satellite navigation system (Beidou satellite, GPS satellite, etc.).

[0044] Example 6

[0045] It should be noted that any one of the above-mentioned solutions has formed a sufficiently complete technical solution. As an additional expandable technical solution, it can also include a terminal APP, which analyzes and processes the collected motion data to obtain further different guidance feedback information. These data information are processed in the functional module of the terminal APP. At the same time, the bone conduction audio device also has a voice interaction function, which can collect the user's voice commands and transmit them to the terminal APP, thereby realizing voice-operated data display, mode switching and other functions.

[0046] The terminal APP can be installed on mobile communication devices, computers and other operational interface devices. The terminal APP includes a swimming navigation and deviation warning module, a safe swimming warning module, a health data detection and reminder function module, a sports data intelligent analysis and training module, a sports data display and storage module, and a terminal audio input and output module.

[0047] Among them, the swimming navigation and deviation warning module is used for open water swimming. It is completed by the positioning chip implanted in the smart goggles body and the swimming navigation system of the APP. The swimming navigation system is realized by combining the open water electric map (the electric map data information comes from the national geographic information resource directory service system platform data) with the satellite navigation system (Beidou satellite, GPS satellite, etc.). Through the intelligent matching function of the swimming navigation system, the best swimming route can be determined. By pre-setting the deviation warning threshold distance in the swimming navigation and deviation warning module, users will prevent deviation under the dual warnings of vision and hearing during the swimming process, ensuring that they swim according to the optimal route set initially.

[0048] Safe swimming warning module: The safe swimming warning module includes dangerous area warning and climate forecast warning functions.

[0049] The dangerous areas include whirlpools, tides, and previous accident cases in open waters (data information on whirlpools, tides, etc. comes from the global tidal forecast service platform; information on previous accident cases comes from relevant platform data). By matching the positioning chip of the above-mentioned smart goggles with the climate forecast data information platform, the real-time climate change at the user's location can be obtained (the climate forecast data information comes from the "World Weather Information Service Official Forecast" platform). By feeding back the location to the safe swimming warning module in real time through the positioning chip, the water area and climate conditions on the optimal route can be evaluated or forecasted in real time. For example, when preparing to swim or during swimming, the safe swimming warning module predicts that there are dangerous areas (such as tides) or dangerous climates (such as thunderstorms) on the optimal route, the system will give the user the best recommended plan, including recommendations to prohibit swimming or take backup plans.

[0050] Health data detection and reminder function module: The health data detection and reminder function module combines the sports data collected by the monitoring sensor with the terminal APP. In the health data detection and reminder function module, the collected sports physiological parameters will be compared and analyzed, including swimming-related data and user health data monitoring. Through analysis and comparison, the system will remind users to pay attention to their physical health, thereby realizing real-time monitoring and reminders for users.

[0051] For example, heart rate monitoring: used to accurately monitor the user's heart rate. These heart rate data will be displayed in real time on the goggles to help users control the intensity and rhythm of swimming and ensure that their physical condition remains within the appropriate range. Smart goggles also have built-in intelligent algorithms to monitor the user's swimming status. If abnormal conditions occur during swimming, such as excessive fatigue or abnormal heart rate, the health data detection and reminder function module will trigger a warning signal to guide the user to take appropriate rest and adjustment measures to ensure the user's safety and health during swimming.

[0052] Intelligent analysis and training module for sports data: The intelligent analysis and training module for sports data includes intelligent analysis and training functions for sports data. The intelligent analysis function for sports data is connected to the cloud platform through the intelligent swimming goggles, and the sports data collected by the multifunctional sensor is intelligently compared and analyzed with the personalized standard model of the cloud platform. With the help of built-in intelligent methods, the user's swimming posture is evaluated in real time through computer vision and deep learning technology, thereby obtaining a personalized recommendation report; if the user's posture is found to be incorrect, the swimming goggles will issue a warning and provide improvement suggestions, such as adjusting arm movements, kicking amplitude, etc., to provide users with professional improvement suggestions for improving swimming skills. Help users better understand their own swimming performance.

[0053] The smart training function can provide rhythm guidance according to the user's goals and water conditions, helping the user to stabilize the swimming rhythm and improve swimming efficiency.

[0054] The smart swimming goggles have built-in advanced swimming style simulation function. The advanced swimming style simulation function is connected to the cloud platform through the image source device. Through augmented reality technology, users can see the swimming style demonstrations of professional swimmers on the cloud platform through the XR visualization lens, helping them learn and imitate more standardized swimming movements.

[0055] Terminal audio input and output module: Through the bone conduction audio device, users can obtain voice interaction commands, which will be transmitted to the terminal APP to realize the voice interaction function. The voice interaction function allows users to control various operations of the multi-functional smart swimming goggles through voice commands, such as starting timing, pausing, switching display information, etc.

[0056] At the same time, the terminal system audio can also be output to the bone conduction audio device to achieve audio feedback guidance. The terminal system audio output includes the audio generated by the terminal device, such as downloaded music or sports beats. In addition, the control end of the terminal APP also provides a voice call outgoing function, so that people can have real-time voice communication. This series of designs not only enhances the user experience, but also provides more convenience for users' operations and communication during swimming.

[0057] Example 7

[0058] The main control module also integrates a sports data display and storage module, so users can observe the data in real time on the XR display lens. The real-time display of sports data includes more important indicators during exercise, such as swimming speed, heart rate, body temperature, water depth, etc.

[0059] As an optional implementation, a large-capacity memory is embedded in the smart goggles as a sports data storage module to record the user's historical data. At the same time, the storage module will synchronize data with the connected terminal APP device, which means that the goggles and the terminal device will save the same data record. This design ensures the security and reliability of the data.

[0060] Smart goggles also support Bluetooth connection or USB interface, which can transfer data to smartphones or computers for easy data analysis, comparison and sharing. This flexible connection method also enables smart goggles to synchronize and interact with other smartphones or devices, including overall sports data, such as total swimming distance, swimming route records and heart rate information. At the same time, the terminal APP that comes with the smart goggles also has a smart sharing social function. With this function, users can share their swimming data and pool pictures on social media platforms, share their swimming experience with friends and family, and increase the fun of interaction and socializing.

[0061] The image source device obtains image data through the terminal APP. The data sources of the terminal APP include user motion data collected from the lidar sensor and multi-function motion sensor on the smart goggles body, as well as data imported from the terminal APP cloud platform. These data are transmitted to the terminal APP via Bluetooth connection, and the functional modules of the terminal APP process and analyze the acquired motion data to generate feedback and guidance information. Finally, this information is transmitted to the XR display system. Under the processing of the XR display system, the user can holographically observe the acquired motion data and feedback guidance information displayed on the XR visualization lens in real time.

[0062] It also includes a function operation touch key module, which is used to operate and control various functions of the smart swimming goggles. Specifically:

[0063] The function operation touch key module is located on the upper outer side of the smart goggles. It is a control module integrated in the XR display system, and the function operation interface can be observed on the XR visualization lens. The touch key module can easily control the functions of the goggles during swimming without stopping to operate or use external devices. Optionally, the touch key module should be equipped with a set of function keys that are easy to identify and operate. The number and layout of function keys can be determined according to design requirements and the functions of goggles. Optionally, the function keys below can be integrated according to different operating methods to reduce the number of touch keys and make the module more compact and convenient. For example, touching the key once is a return command, twice is a confirmation command, and long pressing is a power on and off. The touch key module usually includes the following functions:

[0064] a. Power: used to turn on and off the smart goggles. b. Function switch: used to switch between different function modes, such as swimming data display, music playback, Bluetooth connection, navigation interface, etc. c. Volume adjustment: used to adjust the volume. d. Confirm / Select: used to confirm the selection of menus or functions. e. Return / Cancel: used to return to the previous menu or cancel the current operation.

[0065] Example 8

[0066] As an optional implementation, the smart goggles are equipped with an emergency button 14. When a user encounters an emergency, he can send an emergency signal by pressing the button. The signal will immediately notify the emergency contact set in advance and provide the user's accurate location information. If an excessive danger signal appears and the user cannot adjust it by himself, the health data detection and reminder function module will automatically call the emergency contact set in advance and provide the user's accurate location information for timely rescue.

[0067] Example 9

[0068] like Figure 3 As shown, the multifunctional smart swimming goggles also include a magnetic wireless charging device 3 that can be detached from the goggles, and the components on the swimming goggles are charged by the magnetic wireless charging device. Specifically, the end of the charging head 31 is connected to a plurality of magnetic charging pads 32.

[0069] Specifically, the smart goggles, bone conduction audio device, and the multifunctional motion sensor on the back of the goggle strap all use magnetic wireless charging technology, which can provide good waterproofness and convenient charging. Users do not need to frequently replace batteries, saving maintenance costs and usage costs. With a multi-stick magnetic charger, users only need to bring the charging sticker close to the three devices, and the magnetic charging modules of the three devices will absorb the charging stickers to achieve automatic connection, thereby charging the smart goggles. When charging is complete, users can easily remove the charging sticker without additional operations, which improves the convenience of charging.
