Description

Technical Field

[0001] The present invention relates to the field of earphone testing technology, and in particular to a heart rate monitoring function testing device for a smart wearable product. Background Art

[0002] Whether the heart rate is normal or not is one of the key indicators to measure the health status of an individual. Continuous monitoring and in-depth understanding of changes in personal heart rate, through adjusting diet structure, increasing physical exercise and other lifestyle improvement measures, are crucial to maintaining the overall health of the human body. Given that human body functions are not static and constant, but show differences in heart rate with changes in different time periods and physiological states, timely capturing and understanding these heart rate fluctuations is of forward-looking significance for preventing potential health problems.

[0003] At present, the vigorous development of smart wearable technology has promoted the continuous emergence of smart wearable products such as sports bracelets and smart watches in the market. Among them, a considerable number of smart wearable products focus on monitoring human health indicators, covering multiple dimensions such as sports performance, heart rate monitoring, and sleep quality. In this context, heart rate sensors have become an indispensable and important part of these smart wearable products and have been widely used.

[0004] In the manufacturing process of smart wearable products, in order to ensure the accuracy of its heart rate monitoring function, the heart rate sensor must be strictly tested using professional testing equipment. However, in existing technical means, the gray card reflectance value test and light leakage test for the heart rate sensor often need to rely on two different testing devices to complete. This means that the same smart wearable product needs to be placed in two testing devices for testing separately. This process not only significantly increases production costs, but also prolongs the test cycle, thereby reducing overall work efficiency.

[0005] Therefore, it has become an urgent problem to optimize and improve the current technical solutions.

For technicians in the technical field to which the present application belongs, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0081] In view of the defects of the above-mentioned prior art, the applicant, based on many years of rich practical experience and professional knowledge in this field, and in conjunction with the application of theory, actively conducts research and innovation in the hope of creating a technology that can solve the defects of the prior art. After continuous research and design, and after repeated trial production and improvement, the present invention with real practical value was finally created.

[0082] Please refer to Figure 1-2 The embodiment of the present invention provides a heart rate monitoring function test device for a smart wearable product, including a test bench 1, a host computer 2, a bearing mechanism 3, a light leakage detection mechanism 4 and a gray card reflection value detection mechanism 5. These components perform their respective functions on the test bench 1 and are reasonably arranged.

[0083] Specifically, the host computer 2, the carrying mechanism 3, the light leakage detection mechanism 4 and the gray card reflection value detection mechanism 5 are respectively arranged on the test bench 1, ensuring the high integration and test efficiency of the entire test process;

[0084] The supporting mechanism 3 is used to place the smart wearable product to be tested, providing a stable foundation for subsequent tests;

[0085] The light leakage detection mechanism 4 is arranged outside the carrying mechanism 3 and can move toward or away from the carrying mechanism 3. When approaching the carrying mechanism 3, it is used to fit with the window of the heart rate sensor of the smart wearable product to cover the window and perform light leakage detection on the heart rate sensor, thereby facilitating screening out poor optical structure between the LED and the heart rate sensor caused by assembly, thereby ensuring the reliability of the heart rate sensor in actual use;

[0086] The gray card reflection value detection mechanism 5 is arranged outside the carrying mechanism 3, and can move toward or away from the carrying mechanism 3, and is used to face the window of the heart rate sensor when approaching the carrying mechanism 3, so as to reflect the light emitted by the heart rate sensor, and perform gray card reflection value detection on the heart rate sensor, so as to facilitate the detection of whether the reflection values ​​of the three-color LED and the heart rate sensor are normal, ensure the consistency after wearing, and ensure its accuracy in actual use;

[0087] The host computer 2 plays the role of the central nervous system in the entire test device. It is electrically connected to the supporting mechanism 3, the light leakage detection mechanism 4, the gray card reflection value detection mechanism 5 and the heart rate sensor, respectively, to coordinate the work of each mechanism to ensure the smooth progress of the test process, and receive the detection data of the heart rate sensor and analyze it, thereby providing strong data support for the screening or optimization of the heart rate monitoring function of smart wearable products.

[0088] During the execution of the test process, all test data will be displayed in real time and recorded and saved by the host computer 2. This step ensures the integrity and traceability of the data. The saved data is not only convenient for subsequent analysis and reference, but also can be compared and verified with the data before saving. Through this comparison mechanism, we can effectively prevent the problem of failure to successfully save test data due to operational errors, system failures or other potential factors, thereby greatly improving the accuracy and reliability of the test results.

[0089] It is understandable that when dealing with specific types of smart wearable products, such as TWS (True Wireless Stereo) headphones, in order to further improve the test efficiency, the present invention can flexibly make adaptive improvements and design an innovative 1-to-2 test device. Specifically, the device configures the supporting mechanism 3 and the gray card reflection value detection mechanism 5 into two, corresponding to the test requirements of the left earphone and the right earphone respectively. This design enables the left earphone and the right earphone to perform gray card reflection value detection at the same time, greatly improving the test efficiency.

[0090] At the same time, the light leakage detection mechanism 4 has also been specially designed to be able to perform light leakage detection on both the left and right earphones at the same time. This improvement not only maintains the high accuracy of the test, but also significantly shortens the test time, providing strong technical support for the rapid development and launch of TWS earphones.

[0091] It is worth noting that the test device of the present invention is not only applicable to various styles of TWS headphones currently on the market, but also shows extremely high flexibility and scalability. This means that as TWS headphone technology continues to develop and new styles continue to emerge, the test device of the present invention can quickly adapt to these changes without a lot of redesign and development work, thereby greatly shortening the product development cycle and testing costs.

[0092] In addition, the present invention can also serve as a reference standard for industry solutions, providing valuable reference experience for other manufacturers. Chip manufacturers can promote the design concept and technical solution of this test device to the entire industry, helping other manufacturers to save tedious feasibility analysis and device development cycle, and jointly promote the rapid development and popularization of TWS headset technology. This contribution not only reflects the technical value of the present invention, but also highlights its positive role in promoting industry progress.

[0093] Please refer again Figure 1-2 , and combined with reference Figure 3 , in order to deeply understand a specific implementation of this embodiment. In this embodiment, the bearing mechanism 3 is cleverly subdivided into two functional modules: a bearing component 31 and a fixing component 32.

[0094] The bearing assembly 31, as the core supporting part of the test device, is mainly responsible for providing a stable and adaptable placement platform for accurately placing the smart wearable product to be tested. This design ensures the stability of the smart wearable product during the test process and lays a solid foundation for the subsequent light leakage detection and gray card reflection value detection.

[0095] The fixing component 32 is cleverly arranged outside the bearing component 31 and has the ability to move toward or away from the bearing component 31. When the fixing component 32 is close to the bearing component 31, it can form a tight contact with the smart wearable product placed on the bearing component 31, thereby achieving a tight fixation of the smart wearable product. This design not only ensures that the smart wearable product will not be displaced or shaken during the test, but also greatly improves the accuracy and reliability of the test.

[0096] It is worth noting that the movement mode of the fixing component 32 can be flexibly designed according to actual needs, such as using mechanical transmission, pneumatic or electric methods to achieve fast, stable and accurate fixing operations. At the same time, the material and structure of the fixing component 32 also need to be carefully selected according to the characteristics and test requirements of the smart wearable product to ensure that the smart wearable product will not be damaged during the fixing process.

[0097] In summary, through the coordinated work of the bearing assembly 31 and the fixing assembly 32, the bearing mechanism 3 in this embodiment not only provides a stable and reliable test platform for the smart wearable product, but also ensures the accuracy and efficiency of the test through a flexible fixing method. This design not only improves the overall performance of the test device, but also provides strong technical support for the quality control of smart wearable products.

[0098] Please refer again Figure 3 , and combined with reference Figure 4-5 , in order to deeply understand another specific implementation detail in this embodiment. In this embodiment, the bearing assembly 31 is carefully designed as a complex system composed of multiple key components, aiming to meet the diverse needs of smart wearable products during the detection process.

[0099] The base block 311, as a stable foundation for the bearing assembly 31, not only bears the weight of the entire system, but also provides a precise installation position for other components. Below the base block 311, a first driver 315 is cleverly placed, which serves as a power source and provides the necessary driving force for the movement of the entire system.

[0100] The adjustment hole 316 is carefully opened on the base block 311. Its design not only takes into account the accuracy of movement, but also takes into account the stability of the structure. The first connecting member 314, as a key component connecting the first driver 315 and the second bearing block 313, is cleverly inserted into the adjustment hole 316 to achieve stable power transmission.

[0101] The first bearing block 312 is fixedly arranged on the base block 311, providing a stable support point for the smart wearable product. The second bearing block 313 is movably arranged on the base block 311, and is connected to the first bearing block 312 by a clever rotation connection. This design enables the second bearing block 313 to move smoothly and stably along the adjustment hole 316 under the drive of the first driver 315.

[0102] It is particularly worth mentioning that when the gray card reflection value is detected, the coordinated movement of the second bearing block 313 and the first connecting member 314 can accurately adjust the relative angle between the second bearing block 313 and the first bearing block 312. This function is undoubtedly a huge advantage for smart wearable products, especially headphones, which require a specific opening angle for detection. By adjusting the opening angle, it can be ensured that the window of the heart rate sensor of the smart wearable product forms the best alignment relationship with the gray card reflection value detection module 5, thereby improving the accuracy and reliability of the detection.

[0103] In summary, the bearing assembly 31 in this embodiment not only realizes the stable support of the smart wearable product through its ingenious design, but also meets the diverse needs in the gray card reflection value detection process through its flexible adjustment function.

[0104] Please refer again Figure 3 , and combined with reference Figure 6 , in order to deeply understand the detailed structure and working principle of the fixing component 32 in this embodiment. In this embodiment, the fixing component 32 is designed to include a pressing member 321, a second connecting member 322 and a second driver 323, in order to achieve stable compression and fixation of the smart wearable product.

[0105] The second driver 323, as the power core of the fixed assembly 32, is cleverly placed on one side of the base block 311. The selection of this position not only ensures the stable transmission of the driving force, but also avoids interference with other components in the bearing assembly 31, thereby ensuring the compactness of the structure of the entire test device and the smoothness of movement.

[0106] The second connecting member 322, as a key bridge connecting the second driver 323 and the pressing member 321, is located above the first bearing block 312. One end of the second connecting member 322 is closely connected to the output end of the second driver 323, and the other end is firmly connected to the pressing member 321. This design enables the driving force of the second driver 323 to be efficiently transmitted to the pressing member 321, thereby achieving stable compression of the smart wearable product.

[0107] The pressing member 321, as the actuator of the fixing assembly 32, is located below the second connecting member 322 and immediately above the first bearing block 312. Its shape and size are carefully designed to ensure close contact with the smart wearable product and provide sufficient pressure during the pressing process, thereby effectively preventing the displacement or shaking of the smart wearable product during the test.

[0108] It is worth mentioning that the pressing member 321 can move with the second connecting member 322 in a direction close to or away from the first bearing block 312 under the drive of the second driver 323. When the smart wearable product needs to be pressed and fixed, the second driver 323 is started to drive the pressing member 321 to move in a direction close to the first bearing block 312 until it forms a tight contact with the smart wearable product. At this time, the pressure provided by the pressing member 321 firmly fixes the smart wearable product on the bearing assembly 31, providing stable support for subsequent testing work.

[0109] In summary, the fixing component 32 in this embodiment, through its ingenious design, not only achieves stable compression and fixation of the smart wearable product, but also ensures the stability and reliability of the smart wearable product during the test process.

[0110] In one implementation of this embodiment, for the components that are in direct contact with the smart wearable product, namely the first bearing block 312, the second bearing block 313 and the pressing member 321, we use a flexible material with a low friction coefficient to manufacture them. In particular, the material mentioned here can be Teflon (also known as polytetrafluoroethylene, PTFE), which is a material widely used to reduce friction, prevent wear and provide good sliding performance.

[0111] It should be noted that the selection of Teflon material is mainly based on its several key characteristics:

[0112] Low coefficient of friction: Teflon has an extremely low coefficient of friction, which means that when smart wearable products come into contact with these parts, the friction between them is significantly reduced, thereby reducing the possibility of scratches or wear caused by friction.

[0113] Flexibility: Teflon material has a certain degree of flexibility, which enables it to provide better fit and cushioning effect when in contact with smart wearable products. This flexibility helps to evenly distribute pressure during the compression process and avoid product damage caused by excessive local pressure.

[0114] Corrosion resistance: Teflon has good corrosion resistance to a variety of chemicals, which means it can maintain stable performance in a variety of test environments and will not deteriorate or be damaged by chemical erosion.

[0115] High temperature stability: Teflon can maintain stable physical and chemical properties at higher temperatures, which is especially important for smart wearable products that need to be tested under specific temperature conditions.

[0116] By using Teflon materials to manufacture these key components, we can not only protect the appearance of smart wearable products from damage, but also ensure the accuracy and reliability during the testing process. In addition, the easy processing and cost-effectiveness of Teflon materials also make this choice more feasible and efficient in practical applications.

[0117] Please refer again Figure 1-2 , and combined with reference Figure 7-8 , in order to deeply understand the detailed structure and working principle of the light leakage detection mechanism 4 in this embodiment. In this embodiment, the light leakage detection mechanism 4 is designed to include a first motion component 41, a second motion component 42 and a light shielding member 43, aiming to achieve accurate light shielding and light leakage detection of the window of the heart rate sensor of the smart wearable product.

[0118] The light shielding member 43, as a core component of the light leakage detection mechanism 4, is carefully designed and manufactured. It is arranged on the second motion component 42 and can move toward or away from the window of the heart rate sensor under the drive of the second motion component 42, so that when it approaches the window of the heart rate sensor, it fits with the window of the heart rate sensor and thus shields the window;

[0119] It is understandable that its shape, size and material have been strictly screened and tested to ensure that it can fit tightly into the window of the heart rate sensor and effectively block external light, so as to accurately detect light leakage of the heart rate sensor in a dark environment.

[0120] The second motion component 42 is disposed on the first motion component 41, and can move together with the light shielding member 43 toward or away from the supporting mechanism 3 under the drive of the first motion component 41. This design ensures that the light shielding member 43 can be accurately positioned in front of the heart rate sensor window, providing a solid foundation for subsequent light shielding and light leakage detection.

[0121] During the detection process, the first motion component 41 starts working, driving the entire second motion component 42 and the shading member 43 to move toward the direction close to the supporting mechanism 3 until the shading member 43 is accurately positioned directly in front of the heart rate sensor window. Subsequently, the second motion component 42 starts working, driving the shading member 43 to move toward the direction close to the window of the heart rate sensor until it is tightly fitted with the window of the heart rate sensor.

[0122] In summary, the light leakage detection mechanism 4 in this embodiment, through its ingenious design, not only realizes the precise light shielding and light leakage detection of the heart rate sensor window of the smart wearable product, but also ensures the stability, accuracy and reliability of the detection process.

[0123] Please refer again Figure 7-8 , in order to further understand the detailed structure and operation mechanism of the first motion component 41 in this embodiment. In this particular embodiment, the first motion component 41 is carefully conceived to be composed of core components such as a support frame 411, a third driver 412, a screw rod 413 and a fixing block 414.

[0124] The support frame 411, as a stable foundation of the entire first motion assembly 41, provides accurate installation positions and reliable support for other components. Its structural design not only takes into account stability, but also takes into account the requirements of easy installation and maintenance.

[0125] The third driver 412, as the source of driving force, is cleverly placed on the support frame 411. It establishes a tight transmission connection with the screw rod 413 to ensure efficient power transmission. This design enables the third driver 412 to accurately control the rotation speed and direction of the screw rod 413.

[0126] The screw rod 413, as a key transmission component in the first motion assembly 41, is vertically arranged on the support frame 411. Its surface is precisely processed to ensure that the threaded connection with the fixed block 414 is both tight and smooth. When the screw rod 413 rotates under the drive of the third driver 412, the fixed block 414 will perform stable linear motion along the axial direction of the screw rod 413.

[0127] The fixed block 414, as a platform for carrying the second motion assembly 42, is cleverly sleeved on the screw rod 413 and is threadedly connected to the screw rod 413. This design enables the fixed block 414 to move accurately in a straight line along the axial direction of the screw rod 413 when the screw rod 413 rotates. At the same time, the structural design of the fixed block 414 also takes into account stability and load-bearing capacity, ensuring that the second motion assembly 42 and the light shielding member 43 thereon can operate smoothly and reliably.

[0128] After the second motion component 42 is mounted on the fixed block 414, the entire light leakage detection mechanism 4 forms a complete motion system. When the third driver 412 is started, it drives the screw 413 to rotate, thereby driving the fixed block 414, the second motion component 42 and the light shielding member 43 to perform linear motion along the axial direction of the screw 413. This motion process is both smooth and precise, ensuring that the light shielding member 43 can be accurately positioned in front of the heart rate sensor window, providing a solid foundation for subsequent light shielding and light leakage detection work.

[0129] In summary, the first motion component 41 in this embodiment, through its ingenious design, not only realizes the stable and precise driving of the second motion component 42 and the shading member 43, but also provides a strong guarantee for the high-performance operation of the entire light leakage detection mechanism 4.

[0130] Please refer again Figure 7-8 , in order to have a deeper understanding of the detailed structure and working principle of the second motion component 42 in this embodiment. In this particular embodiment, the second motion component 42 is designed to include a fourth driver 421 and a third connecting member 422, in order to achieve precise control and driving of the shading member 43.

[0131] The fourth driver 421, as the power core of the second motion assembly 42, is firmly mounted on the fixed block 414. Its output end is closely connected to one end of the third connecting member 422, ensuring efficient transmission of the driving force. This design enables the fourth driver 421 to accurately control the movement speed and direction of the third connecting member 422 and the shading member 43 thereon.

[0132] The third connecting member 422, as a key bridge connecting the fourth driver 421 and the shading member 43, not only bears the weight of the shading member 43, but is also responsible for transmitting the driving force of the fourth driver 421 to the shading member 43. Its structural design takes into account both strength and stability, as well as flexibility and precision. When the fourth driver 421 is started, it drives the third connecting member 422 to move linearly along a preset path, thereby driving the shading member 43 to move toward the window close to the heart rate sensor.

[0133] The light shielding member 43, as the core component of the light leakage detection mechanism 4, is cleverly connected to the other end of the third connecting member 422. Driven by the fourth driver 421, the light shielding member 43 can accurately reach the position of the heart rate sensor window and fit closely therewith, thereby effectively shielding external light, providing a solid foundation for subsequent light leakage detection work.

[0134] It is worth noting that a close cooperation relationship is formed between the second motion component 42 and the first motion component 41. When the first motion component 41 drives the fixed block 414 and the second motion component 42 and the shading member 43 to perform linear motion along the axial direction of the screw rod 413, the second motion component 42 is responsible for further fine-tuning the position of the shading member 43 on the fixed block 414 to ensure that it is precisely aligned with the heart rate sensor window.

[0135] In summary, the second motion component 42 in this embodiment realizes stable and precise control and driving of the light shielding member 43 through its ingenious design. This design not only improves the accuracy and reliability of the test device, but also provides a more efficient and accurate solution for light leakage detection of smart wearable products.

[0136] In a specific implementation of this embodiment, the shading member 43 is cleverly designed to be a contoured black silicone material. This design choice not only reflects the careful consideration of material properties, but also fully considers various requirements in practical applications.

[0137] First, black silicone has excellent light-shielding performance. Due to its deep color and dense material, black silicone can effectively absorb and block light, ensuring that when the light shielding member 43 is attached to the heart rate sensor window, external light cannot penetrate and interfere with the light leakage detection result.

[0138] Secondly, the contoured design enables the shading piece 43 to fit closely to the window of the heart rate sensor. By precisely imitating the shape and size of the heart rate sensor window, the shading piece 43 can ensure seamless contact when fitted, thereby minimizing the possibility of light leakage. This design not only improves the shading effect, but also enhances the stability and reliability between the shading piece 43 and the heart rate sensor window.

[0139] In addition, the choice of silicone material also brings good flexibility and durability to the light shielding member 43. Silicone has excellent elasticity and resilience, and can maintain the stability of its shape and performance during long-term use. This means that the light shielding member 43 can maintain its accuracy and integrity during multiple bonding and separation processes, thereby extending the service life of the light leakage detection mechanism.

[0140] In summary, the shading member 43 in this embodiment is made of contoured black silicone material, which not only improves the shading performance and stability, but also provides a more efficient and accurate solution for light leakage detection of smart wearable products. This design innovation not only reflects a deep understanding of material properties, but also fully considers various needs in practical applications.

[0141] Please refer again Figure 2 and 5 , and combined with reference Fig. 9 , in order to gain a deeper understanding of the detailed structure and working principle of the gray card reflection value detection mechanism 5 in this embodiment. In this particular embodiment, the gray card reflection value detection mechanism 5 is cleverly designed to include a fifth driver 51 and a gray card 52, in order to achieve accurate measurement of the reflection value of the heart rate sensor.

[0142] The fifth driver 51, as the power source of the gray card reflection value detection mechanism 5, is carefully placed under the base block 311. Its output end is closely connected to the gray card 52, ensuring that the driving force can be efficiently and stably transmitted to the gray card 52. This design enables the fifth driver 51 to accurately control the movement speed and direction of the gray card 52, thereby meeting the high-precision requirements of the reflection value measurement.

[0143] The base block 311, as the basic component that carries the heart rate sensor and fixes the entire test device, has a structural design that not only takes into account stability, but also takes into account the requirements of easy installation and maintenance. In particular, a avoidance hole 317 is opened on the base block 311. This design cleverly provides the necessary space for the movement of the gray card 52, so that the gray card 52 can smoothly pass through the avoidance hole 317 and face the window of the heart rate sensor under the drive of the fifth driver 51.

[0144] The gray card 52, as the core component for measuring the reflection value, has a surface that has been specially treated to have a constant reflectivity. When the gray card 52 moves toward the direction close to the base block 311 under the drive of the fifth driver 51, it will pass through the avoidance hole 317 and face the window of the heart rate sensor. At this time, the heart rate sensor will emit light and shine it on the surface of the gray card 52. Since the gray card 52 has a constant reflectivity, it will reflect the light back in a certain proportion, so that it will be received by the heart rate sensor and converted into an electrical signal for subsequent processing.

[0145] In summary, the gray card reflection value detection mechanism 5 in this embodiment realizes accurate measurement of the reflection value of the heart rate sensor through its ingenious design. This design not only improves the accuracy and reliability of the test device, but also provides a more efficient and accurate solution for the reflection value detection of smart wearable products.

[0146] It is worth noting that a close cooperative relationship is formed between the gray card reflection value detection mechanism 5 and the light leakage detection mechanism 4. After the gray card reflection value detection is completed, the light leakage detection mechanism 4 will be immediately started to accurately detect the light leakage of the heart rate sensor. This design not only improves the overall performance of the test device, but also provides more comprehensive and sophisticated technical support for the quality control of smart wearable products.

[0147] Although the terms such as test bench, host computer and supporting mechanism are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.

[0148] An embodiment of the present invention provides a device for testing the heart rate monitoring function of a smart wearable product. Through a highly integrated structure, it innovatively integrates a light leakage detection mechanism and a gray card reflection value detection mechanism on a test bench, and is assisted by a host computer and a bearing mechanism, thereby realizing a comprehensive and efficient test of the heart rate monitoring function of the smart wearable product. Specifically, the same smart wearable product only needs to be placed in a single test device to complete two necessary tests on the same test bench: on the one hand, the light leakage detection mechanism is used to perform light leakage detection on the heart rate sensor built into the smart wearable product to ensure that the smart wearable product does not leak light, so as to ensure its reliability in actual use; on the other hand, the heart rate sensor is tested for gray card reflection value through an integrated gray card reflection value detection mechanism, and compared with the reflectivity of a standard gray card to verify the performance of the sensor under different reflectivity conditions, so as to ensure its accuracy in actual use.

[0149] This innovative design not only significantly reduces production costs, but also greatly saves valuable space in the production site by reducing the number of test devices and repeated setup steps in the test process. More importantly, since both necessary test steps can be completed at one time in a single test device, the test cycle can be effectively shortened, thereby greatly improving overall work efficiency and providing solid technical support for quality control and rapid market launch of smart wearable products.
