Description

Technical Field

[0001] This application relates to the field of electronic device technology, specifically to a wearable electronic device, a charging device, and an electronic product. Background Technology

[0002] Wearable electronic devices such as smartwatches are portable electronic products that can be worn on the wrist or other parts of the body. They can not only perform the functions of traditional watches, such as checking the time and keeping time, but also provide a variety of functions such as notification reminders, call control, vital sign monitoring, and mobile payment, greatly facilitating users' lives.

[0003] Wearable electronic devices are charged via a charging device. The wearable electronic device has a first electrical connection and a contact portion that can contact the user's skin. Correspondingly, the charging device has a second electrical connection and a positioning groove. The first electrical connection is used to electrically connect with the second electrical connection, enabling the charging device to charge the wearable electronic device. The contact portion mates with the positioning groove to ensure accurate positioning between the charging device and the device body, thus ensuring the stability of the connection between the first and second electrical connections. However, the contact portion and the first electrical connection occupy a large area of ​​the device body surface, which is detrimental to the miniaturization of the wearable electronic device. Utility Model Content

[0004] In view of the above-mentioned shortcomings in related technologies, this application provides a wearable electronic device that is beneficial to the miniaturization of wearable electronic devices.

[0005] To address the aforementioned technical problems, this application provides a wearable electronic device, including a housing and electronic functional components. The electronic functional components include a first electrical connection portion and a user vital sign detection unit. The first electrical connection portion is used for electrical connection with a charging device. The housing has a contact portion facing the user, which includes a positioning boss and a positioning protrusion. The positioning boss is configured to contact the user, and the user vital sign detection unit is disposed on the positioning boss. The first electrical connection portion is disposed on the positioning protrusion. The end face of the positioning boss is circular, and the positioning protrusion is connected to the outer edge of the positioning boss in the circumferential direction. When the first electrical connection portion is electrically connected to the charging device, the contact portion and the charging device are relatively fixed.

[0006] With the above configuration, the wearable electronic device and the charging device are fixed together by the contact part cooperating with the positioning groove, so that the first electrical connection part can be connected to the second electrical connection part more stably. This is beneficial to ensuring the charging efficiency between the charging device and the wearable electronic device, as well as the stability of data transmission between the wearable electronic device and the external device.

[0007] Meanwhile, the structure between the first electrical connection part and the contact part is relatively compact, which can save space for wearable electronic devices, which is conducive to the miniaturization of wearable electronic devices, as well as the miniaturization of charging devices and electronic products.

[0008] Optionally, the edge of the positioning protrusion away from the positioning boss is arc-shaped, and the edge of the positioning protrusion away from the positioning boss is concentric with the positioning boss.

[0009] The above settings can improve the visual effect of wearable electronic devices, and reduce user discomfort and enhance user experience when the positioning protrusion comes into contact with the user.

[0010] Optionally, there are multiple first electrical connections, which are circumferentially spaced around the center of the positioning boss, and each first electrical connection is distributed in a fan-shaped area concentric with the positioning boss.

[0011] The above-described design makes the structure between the first electrical connection part and the contact part more compact, which is beneficial for the miniaturization of wearable electronic devices, and consequently, for the miniaturization of charging devices and electronic products. At the same time, it improves the visual appeal of wearable electronic devices.

[0012] Optionally, the positioning protrusion is provided with multiple connecting grooves, which are circumferentially spaced around the center of the positioning protrusion, and each first electrical connection part is located in a different connecting groove.

[0013] With the above configuration, each connecting groove can protect each first electrical connection part, which helps reduce the probability of damage to the first electrical connection part. At the same time, the second electrical connection part needs to extend into the connecting groove to connect with the first electrical connection part, which helps ensure the stability of the connection between the first electrical connection part and the second electrical connection part.

[0014] Optionally, the end face of the positioning boss is provided with a first opening and a second opening, and a lens is provided on the housing, which covers the first opening and the second opening. The user vital sign detection unit includes a light emitter and a light sensor. The light emitter is located inside the wearable electronic device and is positioned facing the first opening. The light emitter is used to emit light to the user's skin through the first opening. The light sensor is located inside the wearable electronic device and faces the second opening. The light sensor is used to receive the reflected light through the second opening to detect the user's vital signs.

[0015] The above design allows for a more compact structure in wearable electronic devices, saving space and facilitating miniaturization, as well as the miniaturization of charging devices and other electronic products. Furthermore, when worn, the end face of the positioning protrusion contacts the user, improving the accuracy of the user's vital signs detected by the vital sign detection unit.

[0016] Optionally, multiple light sensors and multiple second openings are provided, with multiple light sensors arranged at intervals around the light emitter, multiple second openings arranged at intervals around the first opening, and multiple light sensors facing different second openings.

[0017] With the above settings, the processor can integrate and process information transmitted from different light sensors, which helps to improve the accuracy of user vital signs detected by the user vital signs detection unit.

[0018] Optionally, the wearable electronic device includes an adsorption magnetic component for attracting a connection magnetic component within the charging device, thereby detachably connecting the charging device and the wearable electronic device. When the charging device is connected to the wearable electronic device, the first electrical connection portion is electrically connected to the charging device. Multiple adsorption magnetic components are provided, some of which are located on the first side of the contact portion, and others are located on the second side of the contact portion. Compared to the second side of the contact portion, the first electrical connection portion is closer to the first side of the contact portion, and the number of multiple adsorption magnetic components located on the first side of the contact portion is greater than the number of multiple adsorption magnetic components located on the second side of the contact portion.

[0019] The above configuration ensures a more stable connection between the charging device and the wearable electronic device near the first electrical connection, preventing the first and second electrical connections from separating during charging or data transmission. This helps ensure the charging efficiency between the charging device and the wearable electronic device, as well as the stability of data transmission between the wearable electronic device and external devices.

[0020] Optionally, the plurality of magnetic adsorption elements located on the first side of the contact portion include a first magnetic adsorption element, a second magnetic adsorption element, and a third magnetic adsorption element. The first and second magnetic adsorption elements are spaced apart, and the third magnetic adsorption element is located between the first and second magnetic adsorption elements. The magnetic pole direction of the first magnetic adsorption element is the same as that of the second magnetic adsorption element and opposite to that of the third magnetic adsorption element.

[0021] The above configuration ensures a more stable connection between the charging device and the wearable electronic device near the first electrical connection, preventing the first and second electrical connections from separating during charging or data transmission. This helps ensure the charging efficiency between the charging device and the wearable electronic device, as well as the stability of data transmission between the wearable electronic device and external devices.

[0022] Secondly, embodiments of this application provide a charging device, including: a charging head and a power cord connected to the charging head. The power cord is used to connect to an external power source. The charging head is used to charge a wearable electronic device. The charging head is provided with a positioning groove, which includes a first circular groove and a second groove connected to the outer periphery of the first groove. A second electrical connection portion is provided on the groove wall of the second groove. The second electrical connection portion is used to electrically connect with the wearable electronic device. The contour of the positioning groove matches the contour of the contact portion on the wearable electronic device. When the second electrical connection portion is electrically connected to the wearable electronic device, the positioning groove is used to accommodate the contact portion, and the positioning groove and the contact portion are relatively fixed.

[0023] With the above configuration, the positioning groove and the contact part cooperate to fix the charging device and the wearable electronic device relatively, thereby enabling the first electrical connection part to be connected to the second electrical connection part more stably, which helps to ensure the charging efficiency between the charging device and the wearable electronic device.

[0024] Meanwhile, the structure between the second electrical connection and the positioning groove is relatively compact, which can save space in the charging device, facilitate the miniaturization of the charging device, and also facilitate the miniaturization of wearable electronic devices and electronic products.

[0025] Thirdly, embodiments of this application provide an electronic product, including: a wearable electronic device according to any of the above embodiments and a charging device according to any of the above embodiments.

[0026] With the above configuration, the wearable electronic device and the charging device are fixed together by the contact part cooperating with the positioning groove, so that the first electrical connection part can be connected to the second electrical connection part more stably. This is beneficial to ensuring the charging efficiency between the charging device and the wearable electronic device, as well as the stability of data transmission between the wearable electronic device and the external device.

[0027] Meanwhile, the structure between the first electrical connection part and the contact part is relatively compact, and the structure between the second electrical connection part and the positioning groove is relatively compact, which can save space for wearable electronic devices and charging devices, and is conducive to the miniaturization of wearable electronic devices and charging devices, as well as the miniaturization of electronic products.

[0028] The wearable electronic device provided in this application embodiment has a first electrical connection portion for electrical connection with a charging device. The housing has a user-facing contact portion, which includes a positioning boss and a positioning protrusion. The positioning boss is configured to contact the user, and a user vital sign detection unit is disposed on the positioning boss. The first electrical connection portion is disposed on the positioning protrusion. The end face of the positioning boss is circular, and the positioning protrusion is connected to the outer edge of the positioning boss in the circumferential direction. When the first electrical connection portion is electrically connected to the charging device, the contact portion and the charging device are relatively fixed. By cooperating with the positioning groove, the wearable electronic device and the charging device are relatively fixed, thereby enabling the first electrical connection portion to be stably connected to the second electrical connection portion. This is beneficial for ensuring the charging efficiency between the charging device and the wearable electronic device, as well as the stability of data transmission between the wearable electronic device and external devices. Simultaneously, the structure between the first electrical connection portion and the contact portion is relatively compact, saving space in the wearable electronic device and facilitating miniaturization of both the wearable electronic device and the charging device / electronic product.

Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0041] As used herein, terms such as “equal,” “parallel,” and “perpendicular” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, “equal” includes absolute equality and approximate equality, where an acceptable range of deviation for approximate equality may be, for example, a difference between the two equal items less than or equal to 5% of either one.

[0042] In the embodiments of this application, the directional indications used to explain the structure and movement of different components, such as up, down, left, right, front, and back, are relative. These indications are appropriate when the components are in the positions shown in the figures. However, if the description of the component positions changes, these directional indications will also change accordingly.

[0043] Please refer to Figures 1 to 3 This application provides a wearable electronic device 10. A first electrical connection part 123 is used to electrically connect with a charging device 20 and is disposed on a contact part 111. The structure between the first electrical connection part 123 and the contact part 111 is relatively compact, which can save space in the wearable electronic device 10, which is conducive to the miniaturization of the wearable electronic device 10, as well as the miniaturization of the charging device 20 and the electronic product 1.

[0044] like Figure 1 As shown, this application embodiment provides an electronic product 1, which includes a wearable electronic device 10 and a charging device 20. The wearable electronic device 10 provided in this application embodiment may include at least one of the following: a smartwatch, a sports watch, a smart bracelet, a virtual reality (VR) terminal device, or an augmented reality (AR) terminal device. This application embodiment does not limit the type of wearable electronic device 10 or the wearing location.

[0045] The following embodiments of this application will use a smartwatch as an example to describe the wearable electronic device 10. It should be understood that the wearable electronic device 10 in these embodiments is not limited to a smartwatch. The charging device 20 is used to connect to an external power source and charge the wearable electronic device 10. Alternatively, the charging device 20 is used to connect to an external device, enabling the wearable electronic device 10 to transmit data with the external device. The external device may include at least one of the following: a mobile phone, computer, tablet computer, smartwatch, smart bracelet, in-vehicle equipment, virtual reality (VR) terminal device, or augmented reality (AR) terminal device.

[0046] For example, such as Figure 3 As shown, the charging device 20 may include a charging head 210 and a power cord 220 connected to the charging head 210. The power cord 220 is used to connect to an external power source or external device, and the charging head 210 is detachably connected to the wearable electronic device 10, thereby enabling the charging device 20 to charge the wearable electronic device 10 or to enable the wearable electronic device 10 to transmit data with external devices.

[0047] This application embodiment does not limit the method of connecting the power cord 220 to an external power source or external device. For example, the power cord 220 can be connected to an external power source or external device through at least one of the following connectors: Universal Serial Bus (USB), DC Barrel Connector, or plug. The Universal Serial Bus (USB) interface can include at least one of the following: USB Type-A, USB Type-B, or USB Type-C. This application embodiment also does not limit the number of power cords 220; for example, there can be one power cord 220, or there can be two or more. In examples where there are multiple power cords 220, each power cord 220 can be connected to an external power source or external device in a different way.

[0048] like Figure 1 and Figure 2 As shown, the wearable electronic device 10 includes a housing 110 and electronic functional components disposed on the housing 110. The electronic functional components can perform functions such as time display, timing, message notification, voice call, and user vital sign detection. The housing 110 supports and fixes the electronic functional components, and also protects them to ensure normal and stable operation. This application does not limit the shape of the housing 110; for example, the housing 110 can be circular, elliptical, rectangular, or approximately rectangular.

[0049] The wearable electronic device 10 also includes a strap 130, which is attached to the housing 110. The strap 130 can be wrapped around the user's wrist, ankle, or upper arm to wear the wearable electronic device 10 on the user's body.

[0050] The housing 110 has an upper surface 110a and a lower surface 110b, which are located opposite each other on both sides of the housing 110. When the wearable electronic device 10 is worn by a user, the lower surface 110b can face the user and make contact with the user. Correspondingly, the upper surface 110a is positioned outwards. Electronic functional components may include a display screen 121, which is disposed on the upper surface 110a and can display information such as time, weather, communication, or user vital signs.

[0051] In one example, the electronic functional component may also include earphones 122, with a storage slot on the housing 110 that matches the shape and size of the earphones 122, in which the earphones 122 can be stored.

[0052] The belt body 130 includes a first belt body 131 and a second belt body 132. Both the first belt body 131 and the second belt body 132 are connected to the housing 110 and are disposed opposite each other on both sides of the housing 110. This application embodiment does not limit the materials of the first belt body 131 and the second belt body 132; the materials used to make the first belt body 131 and the second belt body 132 can include at least one of the following: metal, leather, rubber, canvas, or nylon.

[0053] The first strap 131 and the second strap 132 are detachably connected to allow the wearable electronic device 10 to be worn by a user or to be removed from the user. This application embodiment does not limit the method of detachable connection between the first strap 131 and the second strap 132. In some implementations, the first strap 131 and the second strap 132 can be detachably connected via a buckle and a hole. The buckle is located on one of the first strap 131 and the second strap 132, and the hole is located on the other. In other implementations, the first strap 131 and the second strap 132 can be detachably connected via Velcro. For example, one of the first strap 131 and the second strap 132 may include the hook side of the Velcro, and the other may include the loop side of the Velcro.

[0054] like Figure 2 As shown, the electronic functional components also include a battery (not shown) and a first electrical connection portion 123. The battery is located inside the housing 110 and supplies power to other electronic functional components such as the display screen 121 and earphones 122 to enable their normal operation. The first electrical connection portion 123 is electrically connected to the battery and may be exposed on the surface of the housing 110. Correspondingly, as... Figure 3As shown, the charging device 20 has a second electrical connection portion 211, which can be disposed on the charging head 210 and exposed on the surface of the charging head 210. When the wearable electronic device 10 is connected to the charging device 20, the first electrical connection portion 123 can be connected to the second electrical connection portion 211, so that the charging device 20 can charge the battery of the wearable electronic device 10. After the charging device 20 is removed from the wearable electronic device 10, the first electrical connection portion 123 and the second electrical connection portion 211 are separated.

[0055] In some implementations, the first electrical connection 123 and the second electrical connection 211 may each include either a pogo pin connector or a metal contact. For example, the first electrical connection 123 may include a pogo pin connector, and correspondingly, the second electrical connection 211 may include a metal contact. Alternatively, the first electrical connection 123 may include a metal contact, and correspondingly, the second electrical connection 211 may include a pogo pin connector. When the wearable electronic device 10 is connected to the charging device 20, the first electrical connection 123 may contact the second electrical connection 211 to allow the charging device 20 to charge the battery of the wearable electronic device 10.

[0056] In other implementations, the first electrical connection 123 and the second electrical connection 211 may respectively include either a USB Type-C interface or a USB Type-C connector. For example, the first electrical connection 123 may include a USB Type-C interface, and correspondingly, the second electrical connection 211 may include a USB Type-C connector. Alternatively, the first electrical connection 123 may include a USB Type-C connector, and correspondingly, the second electrical connection 211 may include a USB Type-C interface. When the wearable electronic device 10 is connected to the charging device 20, the first electrical connection 123 may plug into the second electrical connection 211 to allow the charging device 20 to charge the battery of the wearable electronic device 10.

[0057] In the above example, the first electrical connection 123 can be disposed on the lower surface 110b of the housing 110. Therefore, when the wearable electronic device 10 is worn by a user, the first electrical connection 123 is covered between the housing 110 and the user's skin, preventing the first electrical connection 123 from being exposed and reducing the risk of damage to the first electrical connection 123. Simultaneously, this improves the visual appeal of the wearable electronic device 10.

[0058] Correspondingly, when the charging device 20 is connected to the wearable electronic device 10, the charging head 210 contacts the lower surface 110b of the housing 110. For example, the housing 110 may have a first arc surface 118, and the charging head 210 may have a second arc surface 215. The shape, size, and curvature of the second arc surface 215 are all matched with the first arc surface 118. Thus, when the charging device 20 is connected to the wearable electronic device 10, the first arc surface 118 can fit against the second arc surface 215, allowing the charging head 210 to connect to the housing 110 relatively stably. This, in turn, allows the first electrical connection part 123 to connect to the second electrical connection part 211 relatively stably, which helps to ensure the charging efficiency between the charging device 20 and the wearable electronic device 10, and also helps to ensure the stability of data transmission between the wearable electronic device 10 and external devices.

[0059] Please combine Figure 2 and Figure 3 The housing 110 has a contact portion 111 protruding from its surface. Correspondingly, the charging head 210 has a positioning groove 212 for accommodating the contact portion 111. When the charging device 20 is connected to the wearable electronic device 10, that is, when the first electrical connection portion 123 is connected to the second electrical connection portion 211, the contact portion 111 is located within the positioning groove 212, and the contact portion 111 is relatively fixed to the positioning groove 212 and the charging device 20. Thus, by the cooperation of the contact portion 111 and the positioning groove 212, the wearable electronic device 10 and the charging device 20 are relatively fixed, thereby enabling the first electrical connection portion 123 to be stably connected to the second electrical connection portion 211. This is beneficial for ensuring the charging efficiency between the charging device 20 and the wearable electronic device 10, and for ensuring the stability of data transmission between the wearable electronic device 10 and external devices.

[0060] The contour of the positioning groove 212 matches the contour of the contact portion 111. Here, "matching" can be understood as the shape and size of the contour of the positioning groove 212 and the contour of the contact portion 111 being the same; or it can be understood as the contour of the positioning groove 212 and the contour of the contact portion 111 having the same shape, with the contour of the positioning groove 212 being slightly larger than the contour of the contact portion 111. Therefore, when the contact portion 111 is located within the positioning groove 212, the contact portion 111 and the positioning groove 212 are less likely to wobble relative to each other, allowing the wearable electronic device 10 to be connected to the charging device 20 more stably. This helps ensure the charging efficiency between the charging device 20 and the wearable electronic device 10, and also helps ensure the stability of data transmission between the wearable electronic device 10 and external devices.

[0061] The contact portion 111 is located on the lower surface 110b of the housing 110. When the wearable electronic device 10 is worn by a user, the contact portion 111 faces the user and makes contact with the user. The contact portion 111 includes a positioning boss 112 and a positioning protrusion 113 that are interconnected, both of which are used for contact with the user. Correspondingly, the positioning groove 212 includes a first groove 213 and a second groove 214 that are interconnected. When the contact portion 111 is located in the positioning groove 212, the positioning boss 112 is located in the first groove 213, and the positioning protrusion 113 is located in the second groove 214.

[0062] Please combine Figure 3 and Figure 4 The end face of the positioning boss 112 is circular. This improves the visual effect of the wearable electronic device 10 and reduces user discomfort when the positioning boss 112 comes into contact with the user, thus enhancing the user experience. Correspondingly, the contour of the first groove 213 matches the positioning boss 112 and can also be circular.

[0063] The positioning protrusion 113 is connected to the outer edge of the positioning boss 112 in the circumferential direction and protrudes to one side of the positioning boss 112. Correspondingly, the contour of the second groove 214 matches the positioning protrusion 113, and the second groove 214 is connected to the outer edge of the first groove 213 in the circumferential direction. Thus, the user can easily align the positioning groove 212 with the contact portion 111 and easily connect the charging device 20 to the wearable electronic device 10. When the contact portion 111 is located in the positioning groove 212, the positioning protrusion 113 can prevent the wearable electronic device 10 and the charging device 20 from rotating relative to each other, so that the wearable electronic device 10 can be stably connected to the charging device 20, which is beneficial to ensuring the charging efficiency between the charging device 20 and the wearable electronic device 10, and also beneficial to ensuring the stability of data transmission between the wearable electronic device 10 and external devices.

[0064] In one embodiment, the edge of the positioning protrusion 113 away from the positioning boss 112 is arc-shaped, and the edge of the positioning protrusion 113 away from the positioning boss 112 is concentrically arranged with the positioning boss 112. This arrangement improves the visual effect of the wearable electronic device 10 and reduces user discomfort when the positioning protrusion 113 comes into contact with the user, thus enhancing the user experience.

[0065] In the above embodiments, the first electrical connection portion 123 can be disposed on the contact portion 111. For example, the first electrical connection portion 123 can be disposed on the positioning protrusion 113. Correspondingly, the second electrical connection portion 211 can be disposed on the groove wall of the positioning groove 212. For example, the second electrical connection portion 211 can be disposed on the groove wall of the second groove 214. With the above arrangement, the structure between the first electrical connection portion 123 and the contact portion 111 is more compact, which can save space in the wearable electronic device 10, which is conducive to the miniaturization of the wearable electronic device 10, as well as the miniaturization of the charging device 20 and the electronic product 1.

[0066] In one embodiment, there can be multiple first electrical connection portions 123 and second electrical connection portions 211, and the number of second electrical connection portions 211 can be equal to the number of first electrical connection portions 123. Each first electrical connection portion 123 is used to connect to a different second electrical connection portion 211. For example, there can be four first electrical connection portions 123 and four second electrical connection portions 211. Of course, there can also be six, eight, or other numbers of first electrical connection portions 123 and second electrical connection portions 211. With the above arrangement, the charging efficiency between the charging device 20 and the wearable electronic device 10 can be improved, or the data transmission efficiency between the wearable electronic device 10 and the external device can be improved. Furthermore, when any first electrical connection portion 123 has poor contact with its corresponding second electrical connection portion 211, the charging device 20 can still charge the wearable electronic device 10 through other first electrical connection portions 123 and second electrical connection portions 211, or the wearable electronic device 10 can still transmit data with the external device through other first electrical connection portions 123 and second electrical connection portions 211.

[0067] In the above example, the charging device 20 can charge the wearable electronic device 10 through at least two pairs of the plurality of first electrical connections 123 and the plurality of second electrical connections 211, namely two first electrical connections 123 and two corresponding second electrical connections 211. At the same time, the wearable electronic device 10 can also transmit data with external devices through at least two other pairs of the plurality of first electrical connections 123 and the plurality of second electrical connections 211.

[0068] In the above example, multiple first electrical connection portions 123 can be arranged circumferentially around the center of the positioning protrusion 112, and each first electrical connection portion 123 is distributed within a fan-shaped area concentric with the positioning protrusion 112. For example, multiple first electrical connection portions 123 can be arranged sequentially at intervals along the extending direction of the positioning protrusion 113. This makes the structure between the first electrical connection portions 123 and the contact portion 111 more compact, which is beneficial for the miniaturization of the wearable electronic device 10, and consequently for the miniaturization of the charging device 20 and the electronic product 1. At the same time, it improves the visual effect of the wearable electronic device 10.

[0069] Correspondingly, a plurality of second electrical connections 211 can be arranged circumferentially around the center of the first groove 213. For example, a plurality of second electrical connections 211 can be arranged circumferentially along the extension direction of the second groove 214. This makes the structure between the second electrical connections 211 and the positioning groove 212 more compact, which is beneficial to the miniaturization of the charging device 20, and further beneficial to the miniaturization of the electronic product 1.

[0070] In one embodiment, please refer to Figure 5 The positioning protrusion 113 is provided with multiple connecting grooves 114, which are circumferentially spaced around the center of the positioning protrusion 112. Each first electrical connection 123 is located in a different connecting groove 114. For example, each first electrical connection 123 can be located at the bottom of a different connecting groove 114. Through this arrangement, each connecting groove 114 can protect a different first electrical connection 123, which helps reduce the probability of damage to the first electrical connection 123. At the same time, the second electrical connection 211 needs to extend into the connecting groove 114 to connect with the first electrical connection 123, which helps ensure the stability of the connection between the first electrical connection 123 and the second electrical connection 211.

[0071] In one implementation, please combine Figure 5 and Figure 6 The charging device 20 and the wearable electronic device 10 can be detachably connected by the connecting magnetic component 230 and the adsorption magnetic component 140. The materials used to make the connecting magnetic component 230 and the adsorption magnetic component 140 can include at least one magnetic material such as iron, cobalt or nickel.

[0072] The connecting magnetic component 230 can be disposed within the charging device 20, and the adsorption magnetic component 140 can be disposed within the wearable electronic device 10. For example, the adsorption magnetic component 140 can be disposed on the housing 110 of the wearable electronic device 10. The adsorption magnetic component 140 is arranged correspondingly to the connecting magnetic component 230, and the magnetic poles of the adsorption magnetic component 140 are opposite to those of the connecting magnetic component 230, so as to attract the connecting magnetic component 230. When the charging device 20 and the wearable electronic device 10 are connected, the connecting magnetic component 230 and the adsorption magnetic component 140 are magnetically connected. With the above arrangement, the user can easily connect the charging device 20 to the wearable electronic device 10 and can easily remove the charging device 20 from the wearable electronic device 10.

[0073] Multiple magnetic adsorption components 140 and multiple magnetic connection components 230 can be provided, and each magnetic adsorption component 140 can be magnetically connected to a different magnetic connection component 230. This allows the charging device 20 to be securely connected to the wearable electronic device 10, which helps to ensure the charging efficiency between the charging device 20 and the wearable electronic device 10, and also helps to ensure the stability of data transmission between the wearable electronic device 10 and external devices.

[0074] In one example, the contact portion 111 has a first side and a second side disposed opposite to each other, and the first electrical connection portion 123 is disposed closer to the first side of the contact portion 111 than the second side of the contact portion 111. Some of the plurality of magnetic adsorption elements 140 are located on the first side of the contact portion 111, and others are located on the second side of the contact portion 111, and the number of magnetic adsorption elements 140 located on the first side of the contact portion 111 is greater than the number of magnetic adsorption elements 140 located on the second side of the contact portion 111. At the same time, the number and arrangement of the connecting magnetic elements 230 match the magnetic adsorption elements 140.

[0075] For example, the magnetic adsorption element 140 may include a first magnetic adsorption element 141, a second magnetic adsorption element 142, a third magnetic adsorption element 143, a fourth magnetic adsorption element 144, and a fifth magnetic adsorption element 145. The first magnetic adsorption element 141, the second magnetic adsorption element 142, and the third magnetic adsorption element 143 may be disposed on the first side of the contact portion 111, and the fourth magnetic adsorption element 144 and the fifth magnetic adsorption element 145 may be disposed on the second side of the contact portion 111.

[0076] A first magnetic adsorption element 141 and a second magnetic adsorption element 142 are spaced apart. A third magnetic adsorption element 143 is located between the first and second magnetic adsorption elements 141 and 142. The magnetic pole direction of the first magnetic adsorption element 141 is the same as that of the second magnetic adsorption element 142 and opposite to that of the third magnetic adsorption element 143. A fourth magnetic adsorption element 144 and a fifth magnetic adsorption element 145 are spaced apart, and the magnetic pole direction of the fourth magnetic adsorption element 144 is opposite to that of the fifth magnetic adsorption element 145.

[0077] Correspondingly, the connecting magnetic component 230 includes a first connecting magnetic component 231, a second connecting magnetic component 232, a third connecting magnetic component 233, a fourth connecting magnetic component 234, and a fifth connecting magnetic component 235. The first connecting magnetic component 231, the second connecting magnetic component 232, and the third connecting magnetic component 233 are disposed on one side of the positioning groove 212 and are respectively disposed corresponding to the first adsorption magnetic component 141, the second adsorption magnetic component 142, and the third adsorption magnetic component 143. The fourth connecting magnetic component 234 and the fifth connecting magnetic component 235 are disposed on the other side of the positioning groove 212 and are respectively disposed corresponding to the fourth adsorption magnetic component 144 and the fifth adsorption magnetic component 145.

[0078] The above configuration ensures a more stable connection between the charging device 20 and the wearable electronic device 10 near the first electrical connection 123, preventing the first electrical connection 123 and the second electrical connection 211 from separating during charging or data transmission. This helps ensure the charging efficiency between the charging device 20 and the wearable electronic device 10, as well as the stability of data transmission between the wearable electronic device 10 and external devices.

[0079] Of course, in other implementations, the charging device 20 and the wearable electronic device 10 can also be detachably connected by at least one of other methods such as plug-in, snap-fit, or bolt connection.

[0080] Please continue to refer to Figure 5 The electronic functional components also include a user vital signs detection unit 124, which can be located inside the housing 110 and is used to detect user vital signs such as heart rate or blood oxygen saturation.

[0081] In one example, the user vital sign detection unit 124 may include a light emitter 125, a photosensor 126, and a processor 127. The light emitter 125 can be used to emit light towards the user's skin, and the photosensor 126 can be used to receive the light reflected by the user's skin and convert the light signal into an electrical signal before transmitting it to the processor 127 to detect the user's vital signs. The light emitter 125 may include at least one of a light-emitting diode (LED) or a laser diode; the photosensor 126 may include at least one of a photodiode, a phototransistor, or a photodetector; and the processor 127 may include at least one of a central processing unit (CPU), a system-on-chip (SOC), or an application-specific integrated circuit (ASIC).

[0082] Accordingly, the housing 110 may have a first opening 115 and a second opening 116. The light emitter 125 may be positioned facing the first opening 115 and emit light towards the user's skin through the first opening 115. The light sensor 126 may be positioned facing the second opening 116 and receive light reflected from the user's skin through the second opening 116. The housing 110 may have a lens 117, which may cover the first opening 115 and the second opening 116 to include the light emitter 125 and the light sensor 126. In one example, the lens 117 may be integrally formed with the housing 110, that is, the housing 110 and the lens 117 together constitute a single molded part.

[0083] In one embodiment, the first opening 115 and the second opening 116 can be located on the end face of the positioning boss 112. This makes the structure of the wearable electronic device 10 more compact, saving space and facilitating miniaturization of the wearable electronic device 10, as well as the charging device 20 and the electronic product 1. Furthermore, when the wearable electronic device 10 is worn by the user, the end face of the positioning boss 112 contacts the user, which helps improve the accuracy of the user's vital signs detected by the user vital sign detection unit 124.

[0084] In some implementations, multiple photosensors 126 and multiple second openings 116 can be provided. The number of second openings 116 can be equal to or unequal to the number of photosensors 126. The multiple photosensors 126 can each face different second openings 116. The multiple photosensors 126 can be spaced around the light emitter 125, and correspondingly, the second openings 116 can be spaced around the first opening 115. For example, there can be three photosensors 126 and four second openings 116, with each photosensor 126 corresponding to three of the four second openings 116.

[0085] With the above settings, the processor 127 can process the information transmitted by different light sensors 126, which helps to improve the accuracy of the user's vital signs detected by the user vital signs detection unit 124.

[0086] In the above example, the light emitter 125 can be positioned close to the center of the positioning protrusion 112, and the plurality of light sensors 126 and the processor 127 can be spaced apart around the center of the positioning protrusion 112. Correspondingly, the first opening 115 can coincide with the center of the positioning protrusion 112, and each of the second openings 116 can be positioned around the center of the positioning protrusion 112. This facilitates the light reception of each light sensor 126 and improves the visual effect of the wearable electronic device 10.

[0087] This application embodiment also provides a charging device 20, which includes a charging head 210 and a power cord 220 connected to the charging head 210. The power cord 220 is used to connect to an external power source. The charging head 210 is used to charge a wearable electronic device 10. The charging head 210 is provided with a positioning groove 212. The positioning groove 212 includes a circular first groove 213 and a second groove 214 connected to the outer periphery of the first groove 213. A second electrical connection portion 211 is provided on the groove wall of the second groove 214. The second electrical connection portion 211 is used to electrically connect with the wearable electronic device 10. The contour of the positioning groove 212 matches the contour of the contact portion 111 on the wearable electronic device 10. When the second electrical connection portion 211 is electrically connected with the wearable electronic device 10, the positioning groove 212 is used to accommodate the contact portion 111, and the positioning groove 212 and the contact portion 111 are relatively fixed.

[0088] With the above configuration, the positioning groove 212 cooperates with the contact part 111 to fix the charging device 20 and the wearable electronic device 10 relatively, thereby enabling the first electrical connection part 123 to be connected to the second electrical connection part 211 more stably. This is beneficial to ensuring the charging efficiency between the charging device 20 and the wearable electronic device 10, as well as the stability of data transmission between the wearable electronic device 10 and external devices.

[0089] Meanwhile, the structure between the second electrical connection part 211 and the positioning groove 212 is relatively compact, which can save space in the charging device 20, which is conducive to the miniaturization of the charging device 20, as well as the miniaturization of the wearable electronic device 10 and the electronic product 1.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or as many of the technical features as possible; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
