Description

Technical Field

[0001] This application relates to the technical field of watches, and more particularly to a frame structure and a smartwatch. Background Technology

[0002] In existing technologies, to improve device integration and reduce costs, many watch models with integrated barometers employ a single unit combining the barometer and microphone. While structurally innovative, this design also presents several technical challenges. Because the barometer's air duct shares the microphone's sound guide, a conflict arises in their performance requirements. To achieve low attenuation and high sensitivity in sound wave reception, the microphone's sound guide needs to be designed to minimize sound loss during transmission and maintain a rapid response. However, the barometer requires stable and unwavering output even under changes in external airflow, such as wind, to accurately measure pressure changes and support functions like floor positioning.

[0003] In practical applications, this design conflict leads to a significant problem: when the device encounters external airflow interference such as wind, the raw data output by the barometer fluctuates. This fluctuation not only affects the measurement accuracy of the barometer but also further leads to inaccurate floor positioning. Floor positioning is an important application of barometers in smart devices, and its accuracy is crucial to user experience. Therefore, how to solve the data fluctuation problem of barometers in windy scenarios and improve the accuracy of floor positioning has become an urgent technical challenge. Utility Model Content

[0004] The purpose of this application is to provide a frame structure and a smartwatch, which adds an independent detection component and arranges the two detection components to form a phase difference. Finally, the phase difference is used to accurately identify the wind scene, and then filtering is applied to prevent the floor positioning from drifting.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] On the one hand, a frame structure is provided, including: a middle frame, a first air pressure detection component and a second air pressure detection component, the first air pressure detection component and the second air pressure detection component are both installed on the middle frame and are arranged diagonally opposite each other, the air intake direction of the first air pressure detection component is opposite to the air intake direction of the second air pressure detection component, so that the first air pressure detection component and the second air pressure detection component form an air pressure phase difference.

[0007] Furthermore, the middle frame is provided with a first air guide hole and a second air guide hole, the first air guide hole being connected to the detection end of the first air pressure detection component, and the second air guide hole being connected to the detection end of the second air pressure detection component.

[0008] Furthermore, the central axis of the first air guide hole is arranged parallel to the central axis of the second air guide hole.

[0009] Furthermore, the straight-line distance between the first air pressure detection component and the second air pressure detection component is s, where 24.73mm≤s≤44.73mm.

[0010] Furthermore, a sealing element is provided between the detection end of the first air pressure detection component and the inner wall of the middle frame.

[0011] Furthermore, the sealing element is an O-ring, the inner diameter of which is between 1.65mm and 1.85mm, and the wire diameter is between 0.5mm and 0.7mm.

[0012] Furthermore, the O-ring is made of nitrile rubber.

[0013] Furthermore, it also includes a radio receiving component, which is disposed on the first air pressure detection component.

[0014] Furthermore, it also includes a bracket, which is installed on the inner side of the middle frame, and the second air pressure detection component is installed on the bracket. The bracket is also provided with a speaker component and a button component.

[0015] Furthermore, a flexible circuit board is provided on the bracket, and the flexible circuit board is connected to the second air pressure detection component, the speaker component and the button component respectively.

[0016] On the other hand, a smartwatch is also provided, including the frame structure as described above, and a main unit disposed inside the middle frame.

[0017] The beneficial effects of this application are as follows: Traditional barometers are prone to data fluctuations in windy environments, leading to floor location drift. This solution, through its dual-detection component design, effectively reduces the impact of wind on the barometer, enhancing the stability and reliability of the device in windy conditions. Simultaneously, by utilizing the phase difference between the two detection components, the influence of wind on the barometer can be more accurately identified, effectively filtering out pressure fluctuations caused by wind and significantly improving the accuracy of floor location. Because the accuracy of floor location is significantly improved, users of smartwatches equipped with this technology will obtain more accurate and stable floor information, thereby enhancing the overall user experience.

[0025] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0028] like Figures 1-5 As shown, this embodiment provides a frame structure, including: a middle frame 1, a first air pressure detection component 2, and a second air pressure detection component 3. The first air pressure detection component 2 and the second air pressure detection component 3 are both installed on the middle frame 1 and are arranged diagonally opposite each other. The air intake direction of the first air pressure detection component 2 is opposite to the air intake direction of the second air pressure detection component 3, so that the first air pressure detection component 2 and the second air pressure detection component 3 form a 180° air pressure phase difference.

[0029] Based on the above scheme, by installing a first air pressure detection component 2 and a second air pressure detection component 3 on the middle frame 1, arranged diagonally opposite each other, the air intake directions of the two detection components are opposite, thus forming a 180° air pressure phase difference. When the device is stationary, the air pressure values ​​measured by the two detection components should be consistent or close. However, in windy conditions, due to differences in wind direction and speed, the two detection components will sense different air pressure changes, resulting in a phase difference. By comparing the air pressure output values ​​of the two detection components and their phase relationship, the system can accurately identify windy conditions. Once a windy condition is identified, the system processes the air pressure data, using the phase difference between the two detection components to filter out air pressure fluctuations caused by wind, thereby preventing floor positioning drift. This processing method effectively improves the accuracy of floor positioning, maintaining stable positioning results even in windy environments.

[0030] Through its innovative framework structure and detection component arrangement, this technical solution not only improves the accuracy of floor positioning but also enhances the stability and reliability of the equipment in windy environments. This design allows the equipment to maintain excellent performance even in complex environments, thereby greatly improving the user experience. When using a smartwatch equipped with this technical solution, users will be able to obtain more accurate and stable floor information and enjoy more convenient and reliable positioning services.

[0031] In some embodiments, the middle frame 1 is provided with a first air guide hole 101 and a second air guide hole 102. The first air guide hole 101 is connected to the detection end of the first air pressure detection component 2, and the second air guide hole 102 is connected to the detection end of the second air pressure detection component 3. The first air guide hole 101 and the second air guide hole 102 provided on the middle frame 1 serve as airflow inlets for the first air pressure detection component 2 and the second air pressure detection component 3, respectively. When external airflow (including natural wind or man-made airflow) passes through, the air guide holes can guide the airflow smoothly into the corresponding air pressure detection component. The first air guide hole 101 guides the airflow to the detection end of the first air pressure detection component 2, while the second air guide hole 102 guides the airflow to the detection end of the second air pressure detection component 3. Due to the design of the air guide holes, the airflow can act more directly and effectively on the air pressure detection component, thereby improving the response speed and accuracy of air pressure measurement.

[0032] Meanwhile, since the two air pressure detection components receive airflow through different air ducts, the changes in airflow they can sense may differ, especially in windy conditions. This difference provides the system with additional information for identifying windy scenarios, further enhancing the system's adaptability to windy environments.

[0033] It is worth noting that the central axis of the first air guide 101 is parallel to the central axis of the second air guide 102. When the central axes of the first air guide 101 and the second air guide 102 are parallel, they can guide external airflow into their respective corresponding air pressure detection components in a parallel and uniform manner. This design ensures the uniformity and stability of airflow during transmission, reducing measurement errors caused by uneven airflow distribution. The parallel arrangement of the air guides also allows the two air pressure detection components to receive similar but slightly different airflow signals. This difference provides the system with an important basis for identifying wind scenarios and calculating air pressure phase differences.

[0034] Optionally, the straight-line distance between the first air pressure detection component 2 and the second air pressure detection component 3 is s, where 24.73mm ≤ s ≤ 44.73mm. Setting the straight-line distance s between the first air pressure detection component 2 and the second air pressure detection component 3 within the range of 24.73mm to 44.73mm is based on a comprehensive consideration of airflow propagation characteristics, the sensitivity of the air pressure detection components, and the overall performance of the system. Within this distance range, the two air pressure detection components can fully detect changes in external airflow while maintaining a certain spatial distance to avoid mutual interference. When external airflow (such as wind) acts, the two detection components can respectively capture the air pressure fluctuations caused by the airflow and form a certain phase difference. This phase difference is an important basis for the system to identify windy scenarios and calculate air pressure changes.

[0035] Furthermore, a sealing element 8 is provided between the detection end of the first air pressure detection component 2 and the inner wall of the middle frame 1. The presence of the sealing element 8 effectively blocks airflow infiltration except through the first air guide hole 101, and reduces the impact of airflow leakage on air pressure measurement, thereby improving measurement accuracy. A stable measurement environment helps the air pressure detection component maintain consistent measurement performance, reduces measurement fluctuations caused by environmental changes, and enhances system stability. At the same time, the sealing element 8 also prevents dust, moisture, and other impurities from entering the interior of the air pressure detection component, reducing component wear and corrosion, and helping to extend the component's service life. By improving the accuracy of air pressure measurement and the stability of the system, more reliable and accurate floor positioning services can be provided to users, thereby improving the overall user experience.

[0036] Furthermore, the sealing element 8 is an O-ring, with an inner diameter between 1.65mm and 1.85mm and a wire diameter between 0.5mm and 0.7mm. As a commonly used sealing element, the O-ring is designed to provide a reliable seal. In this technical solution, the O-ring is installed between the detection end of the first air pressure detection component 2 and the inner wall of the middle frame 1, achieving a tight seal through appropriate compression (0.07mm compression on the inner wall and 0.08mm compression on the outer wall). Its precise dimensional design, with an inner diameter between 1.65mm and 1.85mm and a wire diameter between 0.5mm and 0.7mm, ensures that the O-ring fits tightly against the detection end and the inner wall of the middle frame 1, effectively preventing the intrusion of moisture and other impurities. When external water pressure increases, the O-ring can utilize its elasticity and compression to resist the water pressure, thereby maintaining a dry internal environment and achieving a 20-meter waterproof performance.

[0037] The O-ring is made of nitrile rubber. As a sealing element, the material selection of the O-ring is crucial to its sealing performance. Nitrile rubber, a commonly used waterproofing material, possesses excellent elasticity and water resistance. In this technical solution, the nitrile rubber O-ring is installed between the detection end of the first air pressure detection component 2 and the inner wall of the middle frame 1, achieving a tight seal through appropriate compression (0.07mm compression on the inner wall and 0.08mm compression on the outer wall). The elasticity of nitrile rubber allows the O-ring to adapt to different installation environments and compression levels, while its water resistance ensures that the O-ring maintains good sealing performance in humid or underwater environments, thereby preventing the intrusion of moisture and other impurities and achieving a 20-meter waterproof performance.

[0038] Generally, the system also includes a sound-receiving component, which is mounted on the first barometric pressure detection component 2. The sound guide hole of the sound-receiving component and the first air guide hole 101 of the first barometric pressure detection component 2 are the same, meaning they share a single hole. In this design, the sound-receiving component is cleverly positioned on the first barometric pressure detection component 2, and both share the same hole—the sound guide hole of the sound-receiving component and the first air guide hole 101 of the first barometric pressure detection component 2. This design allows external sound or airflow passing through this hole to be captured by the sound-receiving component for sound acquisition, while simultaneously entering the first barometric pressure detection component 2 for barometric pressure measurement. The shared hole design simplifies the system structure, reduces connections and interfaces between components, thereby improving the system's integration and reliability.

[0039] Preferably, the system further includes a bracket 4, which is mounted on the inner side of the middle frame 1. The second air pressure detection component 3 is mounted on the bracket 4. The bracket 4 also houses a speaker component 5 and a button component 6. A flexible circuit board 7 is mounted on the bracket 4 and connected to the second air pressure detection component 3, the speaker component 5, and the button component 6, respectively. The bracket 4 is designed and mounted on the inner side of the middle frame 1 as a basic structure supporting and connecting the various components. The second air pressure detection component 3 is mounted on the bracket 4 to ensure stable and accurate air pressure detection. Simultaneously, the speaker component 5 and the button component 6 are also integrated on the bracket 4 to meet the needs of audio output and user interaction. To simplify the connection and signal transmission between components, a flexible circuit board 7 is specially provided on the bracket 4. The flexible circuit board 7, with its flexibility and reliability, effectively connects the second air pressure detection component 3, the speaker component 5, and the button component 6, achieving efficient signal transmission and collaborative operation between components.

[0040] By designing bracket 4, multiple components are centrally mounted inside the middle frame 1, optimizing the system's structural layout and making it more compact and orderly. This not only improves the overall aesthetics of the system but also facilitates subsequent maintenance and upgrades. The use of flexible circuit board 7 avoids the limitations of traditional rigid circuit boards, making the connections between components more flexible and reliable. Even in complex operating environments, it ensures the stability and accuracy of signal transmission. Flexible circuit board 7 effectively reduces signal loss and interference during transmission, thereby improving signal transmission efficiency and quality. This is significant for improving the system's response speed and accuracy. By integrating speaker component 5 and button component 6 and optimizing the connections and signal transmission between components, this technical solution provides users with a smoother and more convenient operating experience. Both audio output and user interaction receive timely and accurate responses.

[0041] On the other hand, a smartwatch is also provided, including the frame structure as described above, and a main unit disposed inside the middle frame 1.
