Technical Field

[0003] The present application relates to the field of electronic devices, and in particular to a wearable device. Background Art

[0004] With the rapid development and widespread adoption of wearable devices such as smartwatches and smart bracelets, their functionality is becoming increasingly comprehensive. For example, some existing smartwatches not only display basic time and date functions but also enable health monitoring and network communication. The more features a smartwatch has, the greater its power consumption. Due to the size limitations of smartwatches, batteries cannot be very large, and battery chemistry itself evolves slowly. Therefore, solar power has become an important means of improving the battery life of smartwatches. Therefore, solar power for wearable devices is an urgent issue that needs to be addressed.

[0005] Summary of the Invention

[0006] The present application provides a wearable device that enables the wearable device to achieve a high-efficiency solar charging function while ensuring the mechanical reliability of the wearable device.

[0007] In a first aspect, the present application provides a wearable device comprising a housing, a display screen, and a battery. The display screen and the housing can be fixedly connected and enclosed to form a storage space, and the battery is accommodated in the storage space. The display screen comprises a display panel, a transparent substrate, a first solar panel, and a first cover plate, wherein the transparent substrate is arranged on the side of the display panel facing away from the storage space, and the transparent substrate comprises a first surface facing the storage space; the first solar panel is arranged in a first area of ​​the first surface, and the first solar panel is electrically connected to the battery; the first cover plate is arranged on the side of the first solar panel facing away from the storage space, and optical glue is filled between the first cover plate and the transparent substrate to improve the structural reliability of the display screen while ensuring light transmittance. It can be seen that in this application, the first solar panel is integrated into the display screen. This design can, on the one hand, achieve a high level of waterproof and dustproof effect for the first solar panel and improve the mechanical reliability of the wearable device. On the other hand, it can also improve the solar energy receiving efficiency of the first solar panel, so that the wearable device can use the first solar panel to achieve high-efficiency charging. Moreover, this solar charging method can be realized while the user is wearing it, thereby improving the charging convenience of the wearable device and effectively improving the battery life of the wearable device.

[0008] In some embodiments, the transparent substrate has a complete planar structure, and the first surface of the transparent substrate further includes a second region. The second region is located radially inward of the first region, or the first region can be understood as surrounding the second region. The projection of the display area of ​​the display panel onto the first surface is located within the second region, so that light from the display area of ​​the display panel can be sequentially emitted from the transparent substrate and the first cover plate to exit the display screen.

[0009] In some embodiments, the projection of the display panel on the first surface of the transparent substrate coincides with the first surface of the transparent substrate, that is, the cross-sectional dimensions of the display panel are the same as the cross-sectional dimensions of the transparent substrate. This design allows the surface of the transparent substrate facing the accommodating space to be fully bonded to the display panel, and has low requirements on the thickness of the transparent substrate. Therefore, the transparent substrate can be designed with a relatively small thickness, which helps to reduce the overall thickness of the display screen.

[0010] In some embodiments, there may be multiple first solar panels, each of which may be spaced apart along the circumference of the transparent substrate within the first region. The first cover plate includes an ink layer on a surface facing the accommodating space. The projection of the ink layer on the first surface of the transparent substrate can cover the gaps between adjacent first solar panels, and the projection of the ink layer on the first surface does not overlap with the projection of the first solar panel on the first surface, nor does it overlap with the projection of the display area of ​​the display panel on the first surface. This allows the gaps between adjacent first solar panels to be shielded without affecting the display function of the display screen or the light absorption function of the first solar panel, thereby improving the appearance of the wearable device.

[0011] In one implementation, adjacent first solar panels are electrically connected. For example, wiring is provided in an area of ​​the first region corresponding to the gap between two adjacent first solar panels. The two adjacent first solar panels are electrically connected via the corresponding wiring, thereby connecting multiple first solar panels in series using these wirings. The first and last first solar panels in the multiple series-connected first solar panels can be electrically connected to a battery, respectively, so that all electrical energy generated by the multiple first solar panels is transmitted to the battery for storage.

[0012] In another implementation, multiple first solar panels can also be arranged in parallel, and each first solar panel can be electrically connected to a battery respectively, so that the electrical energy generated by the multiple first solar panels can be transmitted to the battery respectively for storage.

[0013] In some embodiments, there is a gap between the laminated structure formed by the display panel, the transparent substrate, and the first solar panel and the inner wall of the shell, and a first wire is provided in the gap. The two ends of the first wire are electrically connected to the first solar panel and the battery respectively, thereby electrically connecting the first solar panel and the battery through the first wire.

[0014] In some embodiments, the first solar panel is a flexible gallium arsenide solar panel. Gallium arsenide solar material has a high solar energy conversion efficiency. Therefore, the first solar panel made of gallium arsenide solar material can achieve a relatively high power generation capacity within a relatively limited size. Furthermore, the flexible design of the first solar panel can also improve the reliability and impact resistance of the first solar panel.

[0015] In a second aspect, the present application further provides a wearable device comprising a housing, a display, a solar film, and a battery. The display and the housing are fixedly connected to form a storage space, and the battery is accommodated in the storage space. The housing includes a fixing ring, which is arranged around the display. The fixing ring is made of a transparent material and at least partially covers the side of the display facing away from the storage space. The solar film is arranged on the inner surface of the fixing ring and is electrically connected to the battery. In the present application, placing the solar film on the inner surface of the fixing ring not only improves the light absorption effect of the solar film, but also provides a high level of waterproof and dustproof properties for the solar film, thereby ensuring the mechanical reliability of the wearable device.

[0016] In some embodiments, the housing includes a middle frame that can be combined with the display screen to form the aforementioned accommodation space. The fixing ring includes a top wall and side walls, wherein the top wall covers the side surface of the display screen facing away from the accommodation space, and the side walls are arranged around the outer periphery of the display screen. The inner surface of the fixing ring includes a first inner surface, a second inner surface, and a third inner surface, wherein the first inner surface at least partially covers the side surface of the display screen facing away from the accommodation space, the second inner surface at least partially covers the periphery of the middle frame, and the third inner surface connects the first inner surface and the second inner surface. The solar film can be provided on at least one of the first, second, and third inner surfaces. This structural design can effectively increase the coverage area of ​​the solar film, thereby helping to increase the power generation of the solar film.

[0017] In some embodiments, the first inner surface and the side of the display screen facing away from the accommodating space are filled with waterproof glue, thereby using the waterproof glue to seal between the first inner surface and the side of the display screen facing away from the accommodating space, thereby improving the waterproof and dustproof effect of the solar film. In addition, the second inner surface and the middle frame may also be filled with waterproof glue to seal between the second inner surface and the middle frame, thereby improving the waterproof and dustproof effect of the solar film.

[0018] In some embodiments, the solar film comprises multiple segments along the circumference of the retaining ring, with the segments spaced apart on the inner surface of the retaining ring. The segments can be arranged in parallel, with each segment electrically connected to a battery, so that the electricity generated by the multiple segments is transmitted to the battery for storage.

[0019] In some embodiments, the wearable device may further include one or more functional films disposed on the inner surface of the retaining ring, and the functional films may be adjacent to the solar film. If there are multiple functional films and the solar film includes multiple segments, the multiple functional films and the multiple segments may be alternately disposed. This design can create an alternating color change effect on the outer surface of the retaining ring.

[0020] In one implementation, the functional film can be a conductive film, and the fixing ring can realize the antenna function through the conductive film. In another implementation, the functional film can be a decorative film. By selecting a suitable decorative film and solar film, the outer surface of the fixing ring can achieve a good appearance.

[0021] In some embodiments, a first lead hole is provided in the housing, the first lead hole being in communication with the accommodating space, a second wire is provided in the first lead hole, and two ends of the second wire are electrically connected to the solar film and the battery, respectively, thereby electrically connecting the solar film and the battery via the second wire.

[0022] In other embodiments, the housing includes a middle frame, which encloses the display screen to form a housing space, and the fixing ring may cover at least a portion of the middle frame. A second gap may be defined between the middle frame and the display screen, and a second wire may be disposed in the second gap. The ends of the second wire are respectively electrically connected to the solar film and the battery, thereby electrically connecting the solar film and the battery via the second wire.

[0023] In some embodiments, the wearable device further includes a fixing strap, at least one of the shells includes a connecting portion, the fixing strap is fixedly connected to the shell through the connecting portion, and the fixing strap can be wrapped around the user's wrist or arm to thereby wear the wearable device on the user's body.

[0024] In some embodiments, the wearable device may further include a second solar panel and a second cover, wherein the second cover is made of a transparent material. At least one connecting portion is provided with a receiving groove, and the second cover is provided to cover the notch of the receiving groove. The second solar panel is provided within the receiving groove, and the second solar panel is electrically connected to the battery. Placing the second solar panel within the receiving groove of the connecting portion not only improves the light absorption efficiency of the second solar panel, but also allows the second cover to provide a high level of waterproof and dustproof protection for the second solar panel, thereby enhancing the mechanical reliability of the wearable device.

[0025] In some embodiments, the notch of the receiving slot is positioned toward the outside of the wearable device. Here, the outside of the wearable device can be understood as the side of the wearable device facing the external environment, or the side of the wearable device facing away from the user's body when worn. In this case, the second cover plate can serve as part of the exterior surface of the wearable device, allowing sunlight to directly illuminate the second cover plate, which in turn penetrates the second cover plate and illuminates the second solar panel within the receiving slot.

[0026] In some embodiments, the second cover is a convex lens, and the focus of the second cover is located on the surface of the second solar panel. By utilizing the distance of the convex lens to focus light, the solar energy density on the surface of the second solar panel can be effectively improved, thereby helping to increase the power generation of the second solar panel.

[0027] In some embodiments, the notch of the receiving groove is arranged toward the inner side of the wearable device. Here, the inner side of the wearable device can be understood as the side of the wearable device facing away from the external environment, or can be understood as the side of the wearable device facing the user's body when worn. The end of the fixing strap connected to the connecting portion can be at least partially opposite to the second cover plate. The outer side of the fixing strap includes a concentrating layer, which can be used to reflect light to the second solar panel. In other words, the second solar panel can receive solar energy through the concentrating layer.

[0028] In addition, the fixing belt may further include a support layer, which is arranged on the inner side of the fixing belt and fixedly connected to the light-collecting layer so as to support and fix the light-collecting layer through the support layer, thereby improving the structural strength of the fixing belt.

[0029] In some embodiments, a second lead hole is provided in the housing, with both ends of the second lead hole communicating with the accommodating space and the accommodating groove, respectively. A third wire is provided in the second lead hole, with both ends of the second wire electrically connected to the second solar panel and the battery, respectively, thereby electrically connecting the second solar panel and the battery via the second wire.

[0030] In some embodiments, the wearable device may further include a third solar panel, which is made of a flexible material. The fixing strap includes a first sub-fixing strap and a second sub-fixing strap, and the first sub-fixing strap and the second sub-fixing strap are detachably connected by a magnetic member. The third solar panel can be arranged on the outside of the first fixing strap, or on the outside of the second sub-fixing strap, or can be arranged on the outside of the first sub-fixing strap and the outside of the second sub-fixing strap respectively. When the user wears the wearable device, the third solar panel can be directly exposed to the outside of the wearable device, so the third solar panel can directly receive solar energy, thereby achieving a better light absorption effect. In addition, by designing the first sub-fixing strap and the second sub-fixing strap to be detachably connected by magnetic attraction, the outer area of ​​the first sub-fixing strap and the second sub-fixing strap can be fully utilized to arrange the third solar panel, thereby increasing the area of ​​the third solar panel and then increasing the power generation of the third solar panel.

[0031] In some embodiments, the fixing belt can be connected to the connecting part through a connecting member, which includes a first end and a second end. The first end is electrically connected to the battery, and the second end is electrically connected to the third solar panel. Therefore, the electrical connection between the third solar panel and the battery can be achieved using the connecting member.

[0064] In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as being limited to the embodiments set forth herein. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted. The words expressing position and direction described in the embodiments of the present application are all explained using the accompanying drawings as examples, but changes may be made as needed, and the changes made are all included in the scope of protection of the present application. The drawings in the embodiments of the present application are only used to illustrate the relative position relationship and do not represent the true proportion.

[0065] It should be noted that the following description sets forth specific details to facilitate understanding of the present application. However, the embodiments of the present application can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotations of the embodiments of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0066] The wearable device provided in the embodiments of the present application can be a portable device or a device that can be integrated into a user's clothing or accessories. The wearable device has computing capabilities and can be connected to a mobile phone and various terminal devices. For example, the wearable device can be a smart watch, smart bracelet, sports bracelet, smart wristband, accessories, etc.

[0067] FIG1 is a schematic structural diagram of a wearable device 1000 provided in an embodiment of the present application. The wearable device 1000 of the embodiment shown in FIG1 is described by taking a smart watch as an example. The wearable device 1000 includes a main body 100 and a fixing strap 200. The fixing strap 200 is connected to both sides of the main body 100. The fixing strap 200 can be wrapped around the user's wrist, arm, leg or other body parts to fix the wearable device 1000 to the user. Among them, the main body 100 can be approximately circular, rectangular or other polygonal shapes, which is not shown in this application. FIG1 shows a case where the main body 100 is circular. It is easy to understand that when the wearable device 1000 is a device such as a smart watch or a bracelet, the main body 100 of the wearable device 1000 is the watch head, and the fixing strap 200 of the wearable device 1000 is the watch strap.

[0068] In some embodiments, the main body 100 includes a shell 110 and a display screen 120, which are fixedly connected and enclosed to form a housing space. The display screen 120 can be used to display images, videos, etc. The display screen 120 can be circular, rectangular, or other regular or irregular shapes. The housing space formed by the display screen 120 and the shell 110 can be used to accommodate various functional modules and electronic components of the wearable device 1000, such as but not limited to circuit boards, processors, batteries, charging management modules, communication modules, sensor modules, audio modules, speakers, receivers, microphones, etc., so that the wearable device 1000 can achieve multiple functions.

[0069] In addition, in this embodiment, the wearable device 1000 can be divided into an inner side and an outer side. The inner side of the wearable device 1000 can be understood as the side of the wearable device 1000 facing away from the external environment, or the side of the wearable device 1000 facing the user's body when worn. Correspondingly, the outer side of the wearable device 1000 can be understood as the side of the wearable device 1000 facing the external environment, or the side of the wearable device 1000 facing away from the user's body when worn. For example, the light-emitting side of the display screen 120 can be understood as facing the external environment and away from the user's body.

[0070] Among them, the communication module may include a mobile communication module and a wireless communication module. The mobile communication module can provide wireless communication solutions including 2G / 3G / 4G / 5G applied on the wearable device 1000, and the wireless communication module can provide wireless communication solutions including wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) network), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication technology (NFC), infrared technology (IR), etc. applied on the wearable device 1000. The sensor module may include one or more of the following: pressure sensor, gyroscope sensor, heart rate sensor, magnetic sensor, motion sensor, distance sensor, proximity light sensor, fingerprint sensor, temperature sensor, touch sensor, ambient light sensor, bone conduction sensor, etc.

[0071] In some embodiments, the housing 110 may include a middle frame 1101 and a back shell (not shown in the figure). Along the thickness direction of the main body 100, the back shell is arranged opposite to the display screen 120, one end of the middle frame 1101 is fixedly connected to the display screen 120, and the other end of the middle frame 1101 is fixedly connected to the back shell. Among them, the side where the back shell is located can be the side that contacts the user when the wearable device 1000 is worn. For example, when the wearable device 1000 is a smart watch, the outer surface of the back cover can contact the user's wrist. The outer surface of the back shell can be understood as the side facing the user's body, facing away from the external environment. In one implementation, the back shell and the middle frame 1101 can be integrally formed, that is, the back shell and the middle frame 1101 are an integral structure. In another implementation, the back shell and the middle frame 1101 are split structures, and the back shell can be fixedly connected to the middle frame 1101 by bonding or other means.

[0072] The housing may also include a retaining ring 130, which is arranged in an annular shape around the display screen 120 and is fixedly connected to the middle frame 1101. The retaining ring 130 at least partially covers the surface of the display screen 120 facing away from the storage space, that is, partially covers the light-emitting side of the display screen 120. In one implementation, the retaining ring 130 and the middle frame 1101 can be integrally formed. In another implementation, the retaining ring 130 and the middle frame 1101 can be separate structures. For example, the retaining ring 130 and the middle frame 1101 can be adhesively fixed to each other. The retaining ring 130 can be part of the appearance of the main body 100. For example, if the main body 100 is a smartwatch head, the retaining ring 130 can be considered the bezel of the head. The retaining ring 130 can protect the display screen 120 by reducing the risk of collisions, scratches, or other external damage to the edge of the display screen 120. Furthermore, the retaining ring 130 can enhance the appearance of the wearable device 1000 by adopting different designs and materials. In addition, the surface of the fixing ring 130 may be designed with scales, numbers, or marks to facilitate users to read the time.

[0073] In addition, the middle frame 1101 can be provided with an operation button 11011, which can be electrically connected to the functional module accommodated in the accommodating space. It can perform specific functions in response to the user's rotation or pressing operation, such as controlling the sliding of the display interface of the display screen 120, selecting interactive controls in the display interface of the display screen 120, etc.

[0074] Figure 2 is a schematic structural diagram of the main body of the wearable device provided in an embodiment of the present application. Referring to Figures 1 and 2 together, in an embodiment of the present application, a connecting portion 111 is provided on at least one side of the shell 110, and the fixing belt 200 can be fixedly connected to the shell 110 through the connecting portion 111. For example, in the embodiment shown in Figure 2, connecting portions 111 can be provided on opposite sides of the shell 110, respectively. In one implementation, the connecting portion 111 and the shell 110 can be an integrally molded structure. In another implementation, the connecting portion 111 and the shell 110 can be a split structure, and the connecting portion 111 and the shell 110 can be fixedly connected, or can be detachably connected or movably connected, and this application does not impose any restrictions on this.

[0075] Furthermore, the connection between the fixing strap 200 and the connecting portion 111 may be fixed or detachable, and this application is not limited thereto. In the example where the fixing strap 200 and the connecting portion 111 are detachably connected, the user can replace the fixing strap 200 according to their needs or preferences, thereby helping to expand the application scenarios of the wearable device 1000.

[0076] In one implementation, the fixing strap 200 can be a single piece, with both ends of the fixing strap 200 respectively connected to the two connecting portions 111 of the housing, thereby enclosing the housing 110 to form a wearing space 300. For example, the fixing strap 200 can be made of an elastic material, and the elasticity of the fixing strap 200 can be used to adjust the size of the wearing space 300, so that the wearable device 1000 can meet the wearing requirements of different users.

[0077] In another implementation, the strap 200 includes two sub-straps, defined as a first sub-strap 210 and a second sub-strap 220. One end of the first sub-strap 210 is connected to one connection portion 111 of the housing 110, and one end of the second sub-strap 220 is connected to another connection portion 111 of the housing 110. The first sub-strap 210 and the second sub-strap 220 are detachably connected. When the first sub-strap 210 and the second sub-strap 220 are connected, the first sub-strap 210 and the second sub-strap 220, together with the housing 110, form a wearing space 300, allowing the wearable device to be worn on the user. For example, the first sub-strap 210 and the second sub-strap 220 can be detachably connected via a clasp or magnetically. Both connection methods allow the wearable space 300 of the wearable device 1000 to be adjusted, thereby enabling the wearable device 1000 to meet the wearing needs of different users.

[0078] As mentioned above, the main body of the wearable device 1000 integrates multiple functional modules, and almost all of the functional modules require electric power to operate, so the power consumption demand of the wearable device 1000 is relatively high. Due to the volume limitation of the wearable device 1000, the size of its internal battery is relatively small. It is difficult to ensure that the wearable device 1000 has sufficient battery life by relying solely on the primary storage capacity of the battery. Based on the above considerations, in the embodiment of the present application, the wearable device 1000 can also use solar power generation technology to power its internal modules to improve battery life. The exemplary design of solar technology applied to the wearable device 1000 is specifically described below in conjunction with specific embodiments.

[0079] Figure 3 is a schematic diagram of a cross-sectional structure taken along line AA in Figure 2. Referring to both Figures 2 and 3, in the embodiment of the present application, the display screen 120 includes a display panel 121, a transparent substrate 122, a first solar panel 123, and a first cover plate 124. The display panel 121, the transparent substrate 122, the first solar panel 123, and the first cover plate 124 are stacked in this order, facing away from the accommodating space 140.

[0080] The first cover plate 124 is made of a transparent material, for example, glass. The first cover plate 124 can provide protection and dustproofing for the first solar panel 123, transparent substrate 122, and display panel 121 therein. The display panel 121 includes a display area 121a, which is used to display images or videos. In addition, the display panel 121 may also include a peripheral area 121b, which is arranged around the display area 121a and can be used for wiring. The display panel 121 can be a liquid crystal display (LCD), an organic light emitting diode (OLED), an active-matrix organic light emitting diode or an active-matrix organic light emitting diode (AMOLED), a flexible light emitting diode (FLED), a sub-millimeter light emitting diode (Mini-Led), a micro light emitting diode display (MicroLed), a micro organic light emitting diode (Micro-OLED), a quantum dot light emitting diode (QLED), etc. In addition, in some implementations, the display panel 121 can also integrate a touch function.

[0081] Continuing with FIG. 3 , in the embodiment of the present application, the transparent substrate 122 includes a first surface 1221 facing away from the accommodating space. The first surface 1221 includes a first region 1221a. The first region 1221a may be annular, and the first region 1221a and the projection of the display area 121a of the display panel 121 on the first surface 1221 do not overlap. A first solar panel 123 is disposed within the first region 1221a. The first solar panel 123 can receive solar energy through the first cover 124 and convert the received solar energy into electrical energy. For example, the first solar panel 123 can be bonded to the first region 1221a using optical adhesive or other types of adhesive. Furthermore, the first solar panel 123 can be fixed to the first cover 124 on the side facing the first cover 124, and the transparent substrate 122 can be fixed to the display panel 121 on the side facing the accommodating space 140 using optical adhesive.

[0082] In this embodiment, the first solar panel 123 can have a relatively small thickness, so the first solar panel 123 does not occupy too much of the thickness of the display screen 120, which helps to reduce the space occupied by the display screen 120 in the wearable device. For example, the thickness of the first solar panel 123 can be less than or equal to 0.02 mm. In addition, the first solar panel 123 can be a flexible gallium arsenide solar panel. Gallium arsenide solar material has a high solar energy conversion rate, so the first solar panel 123 made of it can achieve a relatively high power generation capacity with a relatively limited size. In addition, by designing the first solar panel 123 as a flexible structure, the reliability and impact resistance of the first solar panel 123 can be improved.

[0083] Continuing to refer to FIG3 , in the embodiment of the present application, the first solar panel 123 is electrically connected to the battery 150 housed in the accommodating space 140 to transmit the converted electrical energy to the battery 150 to charge the battery 150. Therefore, the wearable device provided in the embodiment of the present application can not only charge the battery 150 through a conventional charger charging method, but also use the first solar panel 123 to replenish the battery 150 in a sunlight environment. Moreover, this solar charging method can be implemented while the user is wearing the wearable device, thereby improving the charging convenience of the wearable device and effectively improving the battery life of the wearable device, thus providing consumers with a better user experience. In addition, if the wearable device runs out of power while the user is wearing it, the solar charging technology can be used to charge the battery 150 in a timely manner, thereby ensuring the user's usage needs at a critical moment. For example, in an extreme outdoor environment and when the wearable device runs out of power, the user can use the power provided by the solar charging technology to enable the wearable device to send a distress signal to ensure their own life safety.

[0084] It should be noted that Figure 3 only shows the battery 150 in the accommodating space 140 by way of example. In a specific implementation, the actual shape, actual size, actual position and actual structure of the battery 150 are not limited by Figure 3. Other functional modules of the wearable device can also be set in appropriate positions according to the internal layout and functional requirements of the accommodating space 140. For example, the space between the battery 150 and the display screen 120 can be used to set up a circuit board and a battery holder.

[0085] In some embodiments, the wearable device further includes a photovoltaic controller (not shown), which can also be housed within the housing space 140. The photovoltaic controller has an input electrically connected to the first solar panel 123, and an output electrically connected to the battery 150. The photovoltaic controller can be used to convert the electrical energy output by the first solar panel 123 into power and output it to the battery 150, thereby controlling parameters such as charging current and voltage to ensure charging stability.

[0086] In some embodiments, the first surface 1221 of the transparent substrate 122 may further include a second region 1221b. The second region 1221b is located on the inner side of the first region 1221a along the radial direction of the transparent substrate 122. This may also be understood as the second region 1221b and the first region 1221a being distributed along the radial direction of the transparent substrate 122. The projection of the display panel 121 on the first surface 1221 is located within the second region 1221b. Thus, in the direction from the first cover plate 124 to the accommodating space 140, the display area 121a of the display panel 121 can be completely exposed within the second region 1221b, allowing light from the display area 121a of the display panel 121 to be sequentially emitted from the transparent substrate 122 and the first cover plate 124 to the outside of the display screen 120. In this embodiment, since the first solar panel 123 has a certain thickness, a certain gap will be formed between the area of ​​the first surface 1221 of the transparent substrate 122 where the first solar panel 123 is not provided and the first cover plate 124. In this embodiment, the gap between the transparent substrate 122 and the first cover plate 124 can be filled with optical glue 125. The filled optical glue 125 can not only improve the structural strength of the display screen 120, but also avoid the gap from having an adverse effect on the display effect of the display screen 120.

[0087] In addition, in this embodiment, the projection of the display panel 121 on the first surface 1221 may overlap with the first surface 1221. In other words, the radial dimension of the display panel 121 is substantially equal to the radial dimension of the transparent substrate 122. In this case, the projection of the peripheral area 121b of the display panel 121 on the first surface 1221 may overlap with the first region 1221a, and the projection of the display area 121a of the display panel 121 on the first surface 1221 may overlap with the second region 1221b. In other embodiments, the radial dimension of the display panel 121 may be slightly smaller than the radial dimension of the transparent substrate 122. The projection of the display panel 121 on the first surface 1221 may be entirely within the second region 1221b. Alternatively, the edge of the projection of the display panel 121 on the first surface 1221 may fall within the first region 1221a. Alternatively, the radial dimension of the display panel 121 may be slightly larger than the radial dimension of the transparent substrate 122, with the projection of the display panel 121 on the first surface 1221 extending beyond the outer edge of the first region 1221a.

[0088] In the aforementioned designs, by designing the transparent substrate 122 as a complete planar structure, the surface of the transparent substrate 122 facing the accommodating space 140 can be fully bonded to the display panel 121. This reduces the thickness requirement for the transparent substrate 122, and thus allows the transparent substrate 122 to be designed to be relatively thin. This helps reduce the overall thickness of the display screen 120, further reducing the space occupied by the display screen 120 in the wearable device. For example, the thickness of the transparent substrate 122 can be less than or equal to 0.05 mm.

[0089] During the assembly process of the display screen 120, the first solar panel 123 can be first bonded and fixed to the first area 1221a of the first surface 1221. Then, the first surface 1221 and the first cover plate 124 are bonded together, and the gap between the two is filled with optical adhesive 125. Finally, the display panel 121 is bonded to the other surface of the transparent substrate 122, thereby forming the display screen 120 integrated with the first solar panel 123. By integrating the first solar panel 123 into the display screen 120, not only can the solar energy receiving efficiency be improved, but the first solar panel 123 can also achieve a high level of waterproof and dustproof effect, thereby helping to improve the overall mechanical reliability of the wearable device.

[0090] Figure 4 is a schematic diagram of a cross-sectional structure at point AA in Figure 2 . Referring to Figure 4 , in some other embodiments of the present application, the transparent substrate 122 may be annular. In this case, the entire area of ​​the first surface 1221 of the transparent substrate 122 may serve as the first area 1221a. The projection of the display area 121a of the display panel 121 onto the first surface 1221 is located within the hollowed-out area within the annular shape of the transparent substrate 122, so that light from the display area 121a of the display panel 121 can be sequentially emitted from the hollowed-out area of ​​the transparent substrate 122 and the first cover plate 124 to exit the display screen. Due to the presence of the transparent substrate 122 and the first solar panel 123, a certain gap is formed between the display panel 121 and the first cover plate 124. In this embodiment, the gap between the display panel 121 and the first cover plate 124 may be filled with optical adhesive 125. This filler can enhance the structural strength of the display screen while maintaining the display quality. Furthermore, the dimensions of the display panel 121 in this embodiment can be designed with reference to the previous embodiments and will not be repeated here.

[0091] Please refer to Figure 3 again. In the embodiment of the present application, in addition to the first cover plate 124, a first gap 112 may be provided between the laminated structure formed by the display panel 121, the transparent substrate 122, and the first solar panel 123 and the inner wall of the housing 110. A first wire 160 may be provided in the first gap 112. One end of the first wire 160 is electrically connected to the first solar panel 123, and the other end of the first wire 160 is electrically connected to the battery 150, thereby electrically connecting the first solar panel 123 and the battery 150 through the first wire 160. It should be noted that in the case where the wearable device includes a photovoltaic controller, the other end of the first wire 160 can be electrically connected to the photovoltaic controller and further electrically connected to the battery 150 through the photovoltaic controller.

[0092] In some embodiments, there can be one first solar panel 123. In this case, the first solar panel 123 can be annular in shape, and the width of the ring of the first solar panel 123 (hereinafter referred to as the "ring width") can be substantially the same as the ring width of the first region 1221a of the transparent substrate 122, or can be slightly smaller than the ring width of the first region 1221a. This can maximize the area of ​​the first solar panel 123 without affecting the display effect of the display area 121a of the display panel 121, thereby increasing the power generation of the first solar panel 123.

[0093] In other embodiments, there may be multiple first solar panels 123, as shown in Figures 5a and 6a, which respectively illustrate schematic planar partial structural diagrams of two display screens 120 provided in embodiments of the present application. Figure 5a illustrates an example of four first solar panels 123, while Figure 6a illustrates an example of eight first solar panels 123. When there are multiple first solar panels 123, the multiple first solar panels 123 may be spaced apart along the circumference of the transparent substrate 122 within the first region 1221a. The first solar panels 123 may be in a fan-shaped ring shape, and the ring width of the first solar panel 123 may be slightly less than or equal to the ring width of the first region 1221a of the transparent substrate 122. Furthermore, the multiple first solar panels 123 may be of the same size, which facilitates control over the size of each first solar panel 123 and helps simplify the manufacturing process and production cost of the display screen 120.

[0094] Figures 5b and 6b respectively show schematic planar structures of two first cover plates provided in embodiments of the present application. Referring to Figures 5a and 5b, and Figures 6a and 6b, in order to prevent the gaps between adjacent first solar panels 123 from being exposed to the light-emitting side of the display screen 120 through the first cover plate 124, in some implementations, the first cover plate 124 has an ink layer 1241 on one side of the surface facing the accommodating space 140. The projection of the ink layer 1241 on the first surface 1221 can cover the gaps between adjacent first solar panels 123, and the projection of the ink layer 1241 on the first surface 1221 does not overlap with the projection of the first solar panel 123 on the first surface 1221. Therefore, the ink layer 1241 can block the gaps between any two adjacent first solar panels 123 without affecting the first solar panel 123 receiving light, thereby improving the appearance of the wearable device. In addition, the projection of the ink layer 1241 on the first surface does not overlap with the projection of the display area of ​​the display panel on the first surface, thereby preventing the ink layer 1241 from affecting the display effect of the display screen. It should be understood that in the example where the first solar panel 123 is in the shape of a full ring, the ink layer may be omitted.

[0095] In some embodiments, adjacent first solar panels 123 can be electrically connected. Within the first region 1221a, the areas corresponding to the gaps between two adjacent first solar panels 123 are provided with traces 12211. These traces 12211 can be electrically connected to two circumferentially adjacent first solar panels 123, respectively. Alternatively, it can be understood that two adjacent first solar panels 123 can be electrically connected via the traces 12211 within the corresponding gaps. In this way, multiple first solar panels 123 can be connected in series. The two first solar panels 123 at the head and tail of the multiple first solar panels 123 connected in series can be electrically connected to a battery, thereby transmitting all the electrical energy generated by the multiple first solar panels 123 to the battery for storage.

[0096] Each trace 12211 can be formed within the first region 1221a by printing, thereby simplifying the manufacturing and assembly process of the display screen 120. Furthermore, because the gaps between adjacent first solar panels 123 are shielded by the ink layer 1241, the traces 12211 located within each gap are also covered by the ink layer 1241 and are not exposed on the light-emitting side of the display screen 120.

[0097] In some other embodiments, multiple first solar panels 123 can be arranged in parallel. In this case, adjacent first solar panels 123 do not need to be electrically connected through the wiring 12211. Each first solar panel 123 is electrically connected to the battery respectively, so that the electric energy generated by each first solar panel 123 is transmitted to the battery for storage.

[0098] In the embodiment of the present application, the first solar panels 123 can be cut from a whole solar panel. By adopting a multi-segment design for the first solar panels 123 within the first region 1221a, the area occupied by each first solar panel 123 is relatively small within the entire solar panel, and the cutting lines of each first solar panel 123 can be arranged relatively densely, thereby effectively improving the utilization rate of the entire solar panel, thereby helping to reduce the production cost of the display screen 120.

[0099] FIG7 is a schematic structural diagram of the light-emitting side of the display screen 120 of the wearable device provided in an embodiment of the present application. Referring to FIG7 , since the gallium arsenide solar material itself has a metallic texture, the first solar panel 123 can achieve a visual effect similar to a metal decorative ring when viewed from the light-emitting side of the display screen 120. In addition, when the first solar panel 123 adopts a multi-segment design, the gaps between adjacent first solar panels 123 can correspond to the characters or scales on the outer fixing ring 130, thereby cooperating with the fixing ring 130 to achieve a good appearance effect for the wearable device. For example, when there are six first solar panels 123, the gaps between adjacent first solar panels 123 correspond to the scales 0, 10, 20, 30, 40, and 50 on the fixing ring 130, respectively.

[0100] Figure 8 is a schematic diagram of another cross-sectional structure taken at point AA in Figure 2 . Referring to Figure 8 , in the embodiment of the present application, the fixing ring 130 is made of a transparent material. For example, the fixing ring 130 can be made of Kunlun glass, sapphire, or other materials with high transmittance to achieve both high appearance and high strength. The wearable device may also include a solar film 400 disposed on the inner surface of the fixing ring 130. This solar film 400 can receive solar energy through the transparent fixing ring 130 and convert the received solar energy into electrical energy. The inner surface of the fixing ring 130 is relative to its outer surface. The outer surface of the fixing ring 130 can be understood as the surface of the fixing ring 130 that serves as the partial exterior surface of the main body 100, i.e., the surface exposed to the outside of the main body 100. The inner surface of the fixing ring 130 can be understood as the surface not exposed to the outside of the main body 100. For example, the solar film 400 can be formed on the inner surface of the fixing ring 130 through an electroplating process.

[0101] The solar film 400 is electrically connected to the battery 150 housed in the housing 140 to transfer the converted electrical energy to the battery 150, thereby charging the battery 150. Similarly, the solar film 400 can also be electrically connected to the battery 150 via a photovoltaic controller, so that the photovoltaic controller can convert the electrical energy output by the solar film 400 and output it to the battery 150 to ensure charging stability. In this embodiment, the wearable device can be charged using conventional charging methods or can use the solar film 400 to replenish the battery in a sunny environment, thereby effectively improving the wearable device's battery life.

[0102] It should be noted that Figure 8 only shows the battery 150 in the accommodating space by way of example. Other functional modules of the wearable device can also be set in appropriate positions according to the internal layout and functional requirements of the accommodating space 140. For example, the space between the battery 150 and the display screen 120 can be used to set up a circuit board and a battery holder.

[0103] FIG9 is an enlarged view of point C in FIG8 . Referring to both FIG8 and FIG9 , in some embodiments, the fixing ring 130 may include a top wall 131 and a side wall 132 , wherein the top wall 131 covers a surface of the display screen 120 facing away from the accommodating space 140 , and the side wall 132 surrounds the outer periphery of the display screen 120 . The inner surface of the fixing ring 130 includes a first inner surface 1311, a second inner surface 1321 and a third inner surface 1322, wherein the first inner surface 1311 is a side surface of the top wall 131 facing the display screen 120, and at least a portion of the first inner surface 1311 covers a side surface of the display screen 120 facing away from the accommodating space 140. The second inner surface 1321 is a side surface of the side wall 132 facing away from the top wall 131, and the second inner surface 1321 at least partially covers the middle frame 1101. The third inner surface 1322 is a surface of the side wall 132 facing the peripheral side of the display screen 120, and the third inner surface 1322 connects the first inner surface 1311 and the second inner surface 1321, and is arranged around the peripheral side of the display screen 120. The solar film 400 can be arranged on at least one of the first inner surface 1311, the second inner surface 1321 and the third inner surface 1322. For example, Figure 9 shows an example in which the first inner surface 1311, the second inner surface 1321 and the third inner surface 1322 are all provided with the solar film 400. This design can effectively increase the coverage area of ​​the solar film 400, thereby helping to increase the power generation of the solar film 400.

[0104] In one implementation, the middle frame 1101 includes a first end surface 113 facing the display screen 120, and the display screen 120 is fixedly connected to the first end surface 113. For example, the first cover plate 124 of the display screen 120 can be used to be fixedly connected to the first end surface 113 of the middle frame 1101, while other layers of the display screen 120, including the display panel, can be located inside the middle frame 1101. For example, the display screen 120 and the first end surface 113 can be fixedly connected using adhesive. In the radial direction of the display screen 120, the edge of the first end surface 113 extends beyond the edge of the display screen 120. Alternatively, the projected edge of the display screen 120 on the first end surface 113 is spaced apart from the edge of the first end surface 113. The second inner surface 1321 of the fixing ring 130 is connected to the area of ​​the first end surface 113 that extends beyond the edge of the display screen 120, thereby positioning the solar film 400 disposed on the second inner surface 1321 between the second inner surface 1321 and the first end surface 113.

[0105] In some embodiments, the edge of the display screen 120 facing away from the accommodating space 140 has a first recessed step 1242. The first inner surface 1311 can be fixed to the stepped surface of the first recessed step 1242, so that the solar film 400 disposed on the first inner surface 1311 is positioned between the first inner surface 1311 and the stepped surface of the first recessed step 1242. The first inner surface 1311 and the stepped surface of the first recessed step 1242 can be sealed with waterproof adhesive 1243, which can wrap around the solar film 400 on the first inner surface 1311 to improve its waterproof and dustproof properties. In one implementation, the stepped surface of the top wall 131 facing away from the first recessed step 1242 is flush with the light-emitting surface of the display screen 120, giving the wearable device a smooth exterior.

[0106] The edge of the first end surface 113 may have a second sunken step 1131. The second inner surface 1321 may be fixed to the stepped surface of the second sunken step 1131. Accordingly, the solar film 400 on the second inner surface 1321 is disposed between the second inner surface 1321 and the stepped surface of the second sunken step 1131. In this case, the third inner surface 1322 partially surrounds the periphery of the display screen 120 and partially surrounds the side of the second sunken step 1131. Similarly, the second inner surface 1321 and the stepped surface of the second sunken step 1131 may be sealed with waterproof adhesive 1132. This waterproof adhesive 1132 can wrap around the solar film 400 on the second inner surface 1321 to enhance its waterproof and dustproof properties.

[0107] The waterproof glue between the first inner surface 1311 and the step surface of the first sunken step 1242, and the waterproof glue between the second inner surface 1321 and the step surface of the second sunken step 1131 can both be formed by dispensing glue. Alternatively, in other implementations, glue can also be poured through the gap between the top wall 131 of the fixing ring 130 and the side surface of the first sunken step 1242, so that the glue fills the gap between the top wall 131 and the side surface of the first sunken step 1242, the gap between the first inner surface 1311 and the step surface of the first sunken step 1242, the gap between the third inner surface 1322 and the peripheral side of the display screen 120, the gap between the third inner surface 1322 and the side surface of the second sunken step 1131, and the gap between the second inner surface 1321 and the step surface of the second sunken step 1131.

[0108] Referring again to FIG8 , in some embodiments of the present application, the solar film 400 and the battery 150 can be electrically connected via a second wire. In specific implementations, the second wire can be arranged within existing gaps between the various structures within the main body, or a lead hole can be provided to accommodate the second wire. This application does not impose any restrictions on this, as long as the second wire can electrically connect the solar film and the battery.

[0109] For example, in one implementation, a first lead hole 114 may be provided in the housing 110, which communicates with the accommodating space 140. Exemplarily, one end of the first lead hole 114 is provided at the first end surface 113 of the middle frame 1101, and the other end of the first lead hole 114 is provided at the inner wall surface of the middle frame 1101. A second wire 170 is provided in the first lead hole 114, one end of the second wire 170 being electrically connected to the solar film 400, and the other end of the second wire 170 being electrically connected to the battery 150. Thus, the solar film 400 and the battery 150 are electrically connected via the second wire 170. This design is equivalent to the aforementioned method of providing additional lead holes.

[0110] In another implementation, a second gap 11012 is provided between the middle frame 1101 and the display screen 120, and a second wire 170 is disposed in the second gap 11012. One end of the second wire 170 is electrically connected to the solar film 400, and the other end of the second wire 170 is electrically connected to the battery 150, thereby electrically connecting the solar film 400 to the battery 150 through the second wire 170. This design is the above-mentioned method of utilizing the existing gaps between the structures.

[0111] In some embodiments, the solar film 400 may include multiple segments 410, as shown in Figures 10a, 10b, 10c, and 10d, respectively, which illustrate schematic planar structural diagrams of four types of fixing rings 130 provided in embodiments of the present application. Figures 10a, 10b, and 10c illustrate exemplary designs of the solar film 400 including two segments 410, four segments 410, and six segments 410, respectively, when the fixing ring 130 is a circular ring. The segments 410 are spaced apart on the inner surface of the fixing ring 130 along the circumference of the fixing ring 130, and the spacing between the segments 410 may be equal or unequal, which is not limited in this application. Figure 10d shows an example in which the solar film 400 includes two segments 410 when the fixing ring 130 is a rectangular ring. The two segments 410 can be respectively arranged on two opposite sides of the fixing ring 130, such as the left and right sides or the upper and lower sides, or the two segments 410 can be respectively arranged on two adjacent sides of the fixing ring 130, such as the left side and the upper side, the right side and the lower side, etc. The example in Figure 10d is a case in which the two segments 410 are respectively arranged on the left and right sides of the fixing ring 130.

[0112] In addition, in the embodiment of the present application, the segments 410 can be arranged in parallel, and each segment 410 is electrically connected to a battery, so that the electrical energy generated by each segment 410 is transmitted to the battery for storage.

[0113] In some embodiments, the wearable device may further include one or more functional films 500 . The one or more functional films 500 may also be disposed on the inner surface of the fixing ring 130 , and the functional films 500 are adjacent to the solar film 400 .

[0114] In one implementation, the functional film 500 may be a conductive film, which may also be formed on the inner surface of the fixing ring 130 by electroplating. The conductive film may enable the fixing ring to function as an antenna, and further enable the wearable device to function as a communication device.

[0115] In another embodiment, the functional film 500 can also be a decorative film, which can also be formed on the inner surface of the fixing ring 130 through electroplating. By selecting a suitable decorative film to match the solar film 400, the outer surface of the fixing ring 130 can achieve a good appearance.

[0116] When the solar film 400 includes multiple segments 410 and there are multiple functional films 500, the multiple segments 410 and the multiple functional films 500 are alternately arranged in sequence along the circumference of the fixing ring 130. This design can make the outer surface of the fixing ring 130 present alternating color changes, giving users a good visual experience.

[0117] FIG11 is a schematic diagram of a partial decomposition structure of the main body 100 of the wearable device provided in an embodiment of the present application. Referring to FIG11 , as previously mentioned, the housing 110 includes at least one connecting portion 111 for connecting to a fixing strap. In an embodiment of the present application, at least one connecting portion 111 may be provided with a receiving groove 1111. The wearable device includes a second solar panel 600 and a second cover plate 700. The second solar panel 600 is disposed in the receiving groove 1111, and the second cover plate 700 covers the notch of the receiving groove 1111. For example, the second cover plate 700 and the notch of the receiving groove 1111 may be sealed with glue to improve the waterproof and dustproof effect of the second solar panel 600.

[0118] In addition, the second cover 700 is made of a transparent material. This allows the second solar panel 600 to receive solar energy through the transparent second cover 700 and convert it into electrical energy. The second cover 700 can be made of Kunlun glass, which, by leveraging its high transmittance, strength, and drop resistance, provides excellent protection for the second solar panel 600 within the receiving slot 1111. Furthermore, because the receiving slot 1111 is formed by a subtractive process in the connection portion 111 of the housing 110, the overall weight of the device is reduced to a certain extent, helping to enhance the user experience.

[0119] The second solar panel 600 can be a flexible gallium arsenide solar panel, so the second solar panel 600 can not only achieve a higher solar energy conversion rate, but also has reliable impact resistance. The second solar panel 600 is electrically connected to the battery contained in the accommodating space to transmit the converted electric energy to the battery to charge the battery. Similarly, the second solar panel 600 can also be electrically connected to the battery through a photovoltaic controller to convert the electric energy output by the second solar panel 600 into power and output it to the battery through the photovoltaic controller to ensure charging stability. In this embodiment, the wearable device can be charged by conventional charging methods, or it can use the second solar panel 600 to supplement the battery with electric energy in a sunlight environment, thereby effectively improving the battery life of the wearable device.

[0120] Continuing to refer to Figure 11, in this embodiment, the notch of the receiving groove is set toward the outside of the wearable device. At this time, the second cover plate 700 can serve as part of the appearance surface of the wearable device, so that sunlight can directly shine on the second cover plate 700, and then penetrate the second cover plate 700 into the receiving groove 1111, and be received by the second solar panel 600 in the receiving groove 1111.

[0121] In one implementation, the second solar panel 600 can be fixed to the bottom of the accommodating groove 1111, the bottom of the accommodating groove 1111 is roughly parallel to the second cover plate 700, and the depth of the accommodating groove 1111 is relatively small. After the second solar panel 600 is set in the accommodating groove 1111, the second solar panel 600 can be fitted with the side of the second cover plate 700 facing the accommodating groove 1111, which can shorten the propagation path of sunlight, thereby reducing the energy loss of sunlight and improving the solar energy receiving efficiency of the second solar panel 600.

[0122] Figure 12 is a schematic diagram of a cross-sectional structure at point BB in Figure 2. Referring to Figure 12, in the embodiment of the present application, the second cover plate 700 is a convex lens structure. In this case, the receiving groove 1111 has a relatively large groove depth. After the second solar panel 600 is placed in the receiving groove 1111, a certain distance can be opened between the second solar panel 600 and the second cover plate 700, so that the focus of the second cover plate 700 can fall on the surface of the second solar panel 600, thereby effectively improving the solar energy density on the surface of the second solar panel 600, so that the second solar panel 600 can achieve a relatively high power generation capacity with a relatively limited size.

[0123] In one implementation, the second solar panel 600 can be fixed to the bottom of the receiving groove 1111 to improve the position stability of the second solar panel 600 in the receiving groove 1111. For example, the second solar panel 600 and the bottom of the receiving groove 1111 can be fixed by bonding.

[0124] In another embodiment, the receiving groove 1111 can also be a through groove, or it can be understood that the receiving groove 1111 extends from the side of the connecting portion 111 facing away from the wearing space to the side of the connecting portion 111 facing the wearing space. In this case, in order to secure the second solar panel 600, a support plate 11111 can be provided in the receiving groove 1111. The support plate 11111 is located on the side of the second solar panel 600 facing away from the second cover plate 700 to support and position the second solar panel 600. For example, the second solar panel 600 and the support plate 11111 can be bonded and fixed, and the support plate 11111 and the groove wall of the receiving groove 1111 can be sealed by dispensing glue.

[0125] In addition, in the two embodiments shown in Figures 11 and 12, the housing 110 may have a second lead hole 115, the two ends of which are respectively connected to the accommodating space 140 and the accommodating groove 1111. A third wire 180 is provided in the second lead hole 115, one end of the third wire 180 is electrically connected to the second solar panel 600, and the other end of the third wire 180 is electrically connected to the battery 150, thereby electrically connecting the second solar panel 600 and the battery 150 through the third wire 180. It should be noted that in the case where the wearable device includes a photovoltaic controller, the other end of the third wire 180 can be electrically connected to the photovoltaic controller, and further electrically connected to the battery 150 through the photovoltaic controller.

[0126] FIG13 is a partial structural cross-sectional view of another wearable device 1000 provided in an embodiment of the present application, and FIG14 is an enlarged view of point D in FIG13 . Referring to FIG13 and FIG14 , in this embodiment, the notch of the receiving groove 1111 is arranged toward the inner side of the wearable device. At this time, the end of the fixing strap 200 connected to the connecting portion 111 is at least partially opposite to the second cover plate 700. The outer side of the fixing strap 200 includes a light-collecting layer 230. After being irradiated by the light-collecting layer 230, light can be reflected within the light-collecting layer 230 and, after being reflected by the light-collecting layer 230, penetrate the second cover plate 700 into the receiving groove 1111 and be received by the second solar panel 600 in the receiving groove 1111. Exemplarily, the material of the light-collecting layer 230 can be polydimethylsiloxane (PDMS). The outer side of the fixing band 200 can be understood as the side of the fixing band 200 formed on the outer side of the wearable device 1000, that is, the side of the fixing band 200 facing the external environment.

[0127] In addition, in this embodiment, the inner side of the fixing strap 200 further includes a support layer 240, and the support layer 240 is fixedly connected to the light-gathering layer 230. For example, the support layer 240 and the light-gathering layer 230 can be fixed by bonding. The material of the support layer 240 is not limited, for example, it can be rubber, leather, nylon, etc., and this application does not impose any restrictions on this. Among them, the inner side of the fixing strap 200 can be understood as the side of the fixing strap 200 that forms the inner side of the wearable device 1000, that is, the side of the fixing strap 200 that faces away from the external environment.

[0128] In the case where the housing 110 includes two connecting portions 111, and the two connecting portions 111 are respectively provided with a receiving groove 1111 for accommodating the second solar panel 600, in one implementation, the wearable device 1000 includes a fixing strap 200, and the entire area outside the fixing strap 200 can be covered by a light-collecting layer 230 to facilitate reflecting light toward the second solar panels 600 in the receiving grooves 1111 of the two connecting portions 111. In another implementation, the wearable device 1000 includes a first sub-fixing strap and a second sub-fixing strap, and the outer sides of the first sub-fixing strap and the outer sides of the second sub-fixing strap can be provided with a light-collecting layer 230 to facilitate reflecting light toward the second solar panels 600 in the receiving grooves 1111 of the two connecting portions 111.

[0129] FIG15 is a partial structural cross-sectional view of another wearable device 1000 provided in an embodiment of the present application. Referring to FIG15 , in an embodiment of the present application, the wearable device 1000 includes a first sub-strap 210, a second sub-strap 220, and a third solar panel 800. The third solar panel 800 is made of a flexible material and can be disposed on the outside of the first sub-strap 210, or on the outside of the second sub-strap 220. Alternatively, the third solar panel 800 can be disposed on the outside of the first sub-strap 210 and the outside of the second sub-strap 220, respectively. When the user wears the wearable device 1000, the third solar panel 800 can be exposed to light, so that the third solar panel 800 can directly receive solar energy and convert the received solar energy into electrical energy.

[0130] Exemplarily, the third solar panel 800 can be a flexible gallium arsenide solar panel, so the third solar panel 800 can not only achieve a higher solar energy conversion rate, but also have reliable impact resistance. The third solar panel 800 is electrically connected to the battery 150 housed in the accommodating space 140 to transmit the converted electric energy to the battery to charge the battery. Similarly, the third solar panel 800 can also be electrically connected to the battery 150 through a photovoltaic controller, so that the photovoltaic controller can convert the electric energy output by the third solar panel 800 into power and output it to the battery 150 to ensure charging stability. In this embodiment, the wearable device 1000 can be charged by conventional charging methods, or the third solar panel 800 can be used to supplement the battery 150 with electric energy in a sunlight environment, thereby effectively improving the battery life of the wearable device 1000.

[0131] It should be noted that Figure 15 only shows the battery 150 in the accommodating space 140 by way of example. In a specific implementation, other functional modules of the wearable device 1000 can also be set in appropriate positions according to the internal layout and functional requirements of the accommodating space 140. For example, the space between the battery 150 and the display screen 120 can be used to set up a circuit board and a battery holder.

[0132] In some embodiments, when the first sub-strap 210 is provided with the third solar panel 800, the side of the first sub-strap 210 facing away from the wearing space 300 has a first groove 211. This first groove 211 may extend along the length of the first sub-strap 210, and the third solar panel 800 of the first sub-strap 210 is secured within the first groove 211. For example, the third solar panel 800 of the first sub-strap 210 may be adhesively secured within the first groove 211, and the edge of the third solar panel 800 may be sealed to the wall of the first groove 211 using glue dispensed. Similarly, when the second sub-strap 220 is provided with the third solar panel 800, the side of the second sub-strap 220 facing away from the wearing space 300 has a second groove. This second groove extends along the length of the second sub-strap 220, and the third solar panel 800 of the second sub-strap 220 is secured within the second groove. For example, the third solar panel 800 of the second sub-fixing belt 220 can be adhesively fixed in the second groove, and the edge of the third solar panel 800 and the groove wall of the second groove can be sealed by dispensing glue.

[0133] Continuing with FIG15 , in some embodiments, the first sub-strap 210 and the second sub-strap 220 can be connected to corresponding connecting portions via connectors. For example, the first sub-strap 210 can be connected to one connecting portion 111 of the housing 110 via a first connector 250, and the second sub-strap 220 can be connected to another connecting portion 111 of the housing via a second connector 260. For example, both the first connector 250 and the second connector 260 can be spring ears. Among them, each connecting member includes a first end and a second end. For the first connecting member 250, when the first sub-fixing belt 210 is provided with a third solar panel 800, the first end of the first connecting member 250 can be electrically connected to the battery 150, and the second end of the first connecting member 250 can be electrically connected to the third solar panel 800 of the first sub-fixing belt 210; for the second connecting member 260, when the second sub-fixing belt 220 is provided with a third solar panel 800, the first end of the second connecting member 260 can be electrically connected to the battery 150, and the second end of the second connecting member 260 can be electrically connected to the third solar panel 800 of the second sub-fixing belt 220.

[0134] Alternatively, in some other embodiments, when the third solar panel 800 is disposed in the first sub-fixing strap 210, a third lead hole 212 may be provided in the first sub-fixing strap 210, and a fourth lead hole 116 may be provided in the housing 110. The third lead hole 212 communicates with the fourth lead hole 116, and the third lead hole 212 communicates with the first groove 211, while the fourth lead hole 116 communicates with the accommodating space 140 of the housing 110. A fourth wire 190 is disposed in the third lead hole 212 and the fourth lead hole 116. One end of the fourth wire 190 is electrically connected to the third solar panel 800 in the first groove 211, and the other end of the fourth wire 190 is electrically connected to the battery 150. Thus, the third solar panel 800 in the first groove 211 is electrically connected to the battery 150 via the fourth wire 190.

[0135] When the second sub-fixing band 220 is provided with the third solar panel 800, a fifth lead hole may be provided in the second sub-fixing band 220, and a sixth lead hole may be provided in the housing 110. The fifth lead hole and the sixth lead hole are connected, and the fifth lead hole is connected to the second groove, and the sixth lead hole is connected to the accommodating space 140 of the housing 110. A fifth wire is provided in the fifth and sixth lead holes. One end of the fifth wire is electrically connected to the third solar panel 800 in the second groove, and the other end of the fifth wire is electrically connected to the battery 150, thereby electrically connecting the third solar panel 800 in the second groove to the battery 150 through the fifth wire. It should be noted that when the wearable device 1000 includes a photovoltaic controller, the other end of the fifth wire can be electrically connected to the photovoltaic controller and further electrically connected to the battery 150 through the photovoltaic controller.

[0136] In the embodiment of the present application, the first sub-strap 210 and the second sub-strap 220 are detachably connected via magnetic attraction. For example, a first magnetic member is embedded in the first sub-strap 210, and a second magnetic member is embedded in the second sub-strap 220. When the first sub-strap 210 and the second sub-strap 220 are overlapped, the first magnetic member and the second magnetic member are magnetically attracted to each other, thereby connecting the first sub-strap 210 and the second sub-strap 220.

[0137] In addition, there can be multiple first magnetic members, arranged in sequence along the length of the first sub-strap 210. Similarly, there can be multiple second magnetic members, arranged in sequence along the length of the second sub-strap 220. With this design, the first and second sub-straps 210, 220 can be connected using the magnetic members within their respective overlapping areas at different overlap lengths, thereby enabling the wearable device 1000 to adjust the size of the wearing space 300 to meet the wearing needs of different users. Furthermore, taking the example of the first sub-strap 210 overlapping the second sub-strap 220 when the first sub-strap 210 and the second sub-strap 220 are connected, as the overlap length of the first and second sub-straps 210, 220 changes, the size of the area exposed by the third solar panel 800 on the second sub-strap 220 also changes, thereby varying the amount of power generated by the third solar panel 800 on the second sub-strap 220.

[0138] In this embodiment, the first sub-fixing strap 210 and the second sub-fixing strap 220 are designed to be connected by magnetic attraction. Since there is no need to drill holes in the first sub-fixing strap 210 or the second sub-fixing strap 220, the area on the side of the first sub-fixing strap 210 and the second sub-fixing strap 220 facing away from the wearing space 300 can be fully utilized to arrange the third solar panel 800, thereby increasing the coverage area of ​​the third solar panel 800 and further increasing the power generation of the third solar panel 800.

[0139] The above embodiments respectively introduce several solar charging solutions in which solar panels or solar films are arranged on the display screen, fixing ring, shell and fixing belt of the wearable device. Although the specific implementation forms of each solution are slightly different, they all have the advantages of high solar energy conversion efficiency, good mechanical reliability, support for high-level waterproof and dustproof, and saving internal stacking space of the whole device. It should be noted that any one of the solar charging solutions provided in the above embodiments can be applied to the wearable device alone or in combination with one or more other solutions. In other words, the wearable device can have at least one of the above-mentioned first solar panel, second solar panel, third solar panel, solar film and their related designs, thereby effectively improving the battery life of the wearable device.

[0140] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
