Description

Technical Field

[0001] This application relates to the field of electronic devices, and particularly to a wearable device. Background Art

[0002] With the rapid development and popularization of wearable devices such as smart watches and smart bracelets, the functions of wearable devices are becoming more and more comprehensive. For example, some existing smart watches not only have basic functions of time and date display, but also can realize functions such as health monitoring and network communication. The more functions a smart watch has, the greater the power consumption. Due to the volume limitation of smart watches, the size of the battery in smart watches cannot be made very large, and the technological iteration of the battery chemical system itself is slow. Therefore, solar power supply has become an important means to improve the battery life of smart watches. Thus, the solar power supply of wearable devices is an urgent problem to be solved. Summary of the Invention

[0003] This application provides a wearable device, which can realize high-efficiency solar charging function of the wearable device on the premise of ensuring the mechanical reliability of the wearable device.

[0004] In a first aspect, this application provides a wearable device, which includes a housing, a display screen, and a battery. The display screen is fixedly connected to the housing and encloses to form an accommodation space, and the battery is accommodated in this accommodation space. The display screen includes a display panel, a transparent substrate, a first solar panel, and a first cover plate. Among them, the transparent substrate is arranged on the side of the display panel facing away from the accommodation space, and the transparent substrate includes a first surface facing the accommodation 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 accommodation space, and an optical adhesive is filled between the first cover plate and the transparent substrate to improve the structural reliability of the display screen on the premise of ensuring the 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 on the first solar panel, improve the mechanical reliability of the wearable device, and on the other hand, can also improve the solar energy reception efficiency of the first solar panel, enabling the wearable device to use the first solar panel to achieve high-efficiency charging. And this solar charging method can be realized during the user's wearing process, thus not only improving the charging convenience of the wearable device, but also effectively enhancing the battery life of the wearable device.

[0005] In some embodiments, the transparent substrate is a complete planar structure, and the first surface of the transparent substrate further includes a second area. Along the radial direction of the transparent substrate, the second area is located inside the first area, or it can be understood that the first area surrounds the second area. The projection of the display area of the display panel on the first surface is located in the second area. Therefore, the light of the display area of the display panel can be emitted out of the display screen through the transparent substrate and the first cover plate in sequence.

[0006] 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 to say, the cross-sectional size of the display panel is the same as that of the transparent substrate. This design enables the surface of the transparent substrate facing the accommodation space to be integrally attached to the display panel, with relatively low requirements for the thickness of the transparent substrate. Therefore, the transparent substrate can adopt a relatively small thickness design, which helps to reduce the overall thickness of the display screen.

[0007] In some embodiments, there may be multiple first solar panels, and the multiple solar panels may be arranged at intervals along the circumferential direction of the transparent substrate in the first region. The first cover plate includes an ink layer on the surface facing the accommodation 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 coincide with the projection of the first solar panels on the first surface and the projection of the display area of the display panel on the first surface. This can block the gaps between adjacent first solar panels without affecting the display function of the display screen and the light absorption function of the first solar panels, thereby improving the appearance quality of the wearable device.

[0008] In one implementation, adjacent first solar panels are electrically connected. For example, traces are provided in the region corresponding to the gaps between two adjacent first solar panels in the first region, and the two adjacent first solar panels are electrically connected through the corresponding traces, so as to sequentially connect multiple first solar panels in series using these traces. The first and the last first solar panels among the multiple serially connected first solar panels can be respectively electrically connected to the battery, so as to transmit all the electric energy generated by the multiple first solar panels to the battery for storage.

[0009] In another implementation, multiple first solar panels can also be arranged in parallel, and each first solar panel can be respectively electrically connected to the battery, so that the electric energy generated by the multiple first solar panels is respectively transmitted to the battery for storage.

[0010] 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 housing. A first wire is provided in this gap, and the two ends of the first wire are respectively electrically connected to the first solar panel and the battery, so as to electrically connect the first solar panel and the battery through the first wire.

[0011] In some embodiments, the first solar panel is a flexible gallium arsenide solar panel. The gallium arsenide solar material has a high solar energy conversion rate. Therefore, the first solar panel prepared from the gallium arsenide solar material can achieve a relatively high power generation with a relatively limited size. In addition, designing the first solar panel as a flexible structure can also improve the reliability and impact resistance of the first solar panel.

[0012] In a second aspect, the present application also provides a wearable device, which includes a housing, a display screen, a solar film, and a battery. The display screen is fixedly connected to the housing to form an accommodation space, and the battery is accommodated in the accommodation space. The housing includes a fixing ring that surrounds the display screen. The fixing ring is made of a transparent material and at least partially covers one side surface of the display screen facing away from the accommodation space. The solar film is disposed on the inner surface of the fixing ring and is electrically connected to the battery. In the present application, disposing the solar film on the inner surface of the fixing ring can not only improve the light absorption effect of the solar film, but also achieve high-grade waterproof and dustproof for the solar film, ensuring the mechanical reliability of the wearable device.

[0013] In some embodiments, the housing includes a middle frame, and the middle frame and the display screen can enclose to form the above-mentioned accommodation space. The fixing ring includes a top wall and a side wall. The top wall covers one side surface of the display screen facing away from the accommodation space, and the side wall surrounds the outer peripheral side 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. The first inner surface at least partially covers one side surface of the display screen facing away from the accommodation space, the second inner surface at least partially covers the circumferential side of the middle frame, and the third inner surface connects the first inner surface and the second inner surface. The solar film can be disposed on at least one of the first inner surface, the second inner surface, and the third inner surface. This structural design can effectively increase the coverage area of the solar film, thereby helping to improve the power generation of the solar film.

[0014] In some embodiments, a waterproof adhesive is filled between the first inner surface and one side surface of the display screen facing away from the accommodation space, so as to use the waterproof adhesive to seal between the first inner surface and one side surface of the display screen facing away from the accommodation space, improving the waterproof and dustproof effect on the solar film. In addition, a waterproof adhesive can also be filled between the second inner surface and the middle frame, so as to use the waterproof adhesive to seal between the second inner surface and the middle frame, improving the waterproof and dustproof effect on the solar film.

[0015] In some embodiments, along the circumferential direction of the fixing ring, the solar film includes a plurality of segments, and the plurality of segments are spaced apart and disposed on the inner surface of the fixing ring. The segments can be connected in parallel, and each segment is electrically connected to the battery respectively, so that the electric energy generated by the plurality of segment plates is respectively transmitted to the battery for storage.

[0016] In some embodiments, the wearable device may further include one or more functional films. The one or more functional films are disposed on the inner surface of the fixing ring and are adjacent to the solar film. In the case where there are multiple functional films and the solar film includes multiple segments, the multiple functional films and the multiple segments are alternately arranged in sequence. This design can make the outer surface of the fixing ring present an alternating color change effect.

[0017] In one implementation, the functional film can be a conductive film, and the fixed 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 combination of the decorative film and the solar film, a good appearance effect can be achieved on the outer surface of the fixed ring.

[0018] In some embodiments, a first lead hole is provided in the housing, and the first lead hole communicates with the accommodation space. A second wire is provided in the first lead hole, and both ends of the second wire are electrically connected to the solar film and the battery respectively, so that the solar film and the battery are electrically connected through the second wire.

[0019] In some other embodiments, the housing includes a middle frame, and the middle frame and the display screen enclose to form an accommodation space. The fixed ring can cover at least part of the middle frame. There may be a second gap between the middle frame and the display screen, and a second wire may be provided in the second gap. Both ends of the second wire are electrically connected to the solar film and the battery respectively, so that the solar film and the battery are electrically connected through the second wire.

[0020] In some embodiments, the wearable device further includes a fixing band. At least one of the housings includes a connecting portion, and the fixing band is fixedly connected to the housing through the connecting portion. The fixing band can be wound around the user's wrist or arm, so as to wear the wearable device on the user's body.

[0021] In some embodiments, the wearable device may further include a second solar panel and a second cover plate, and the second cover plate is made of a transparent material. At least one connecting portion is provided with a receiving groove, the second cover plate covers the opening of the receiving groove, the second solar panel is disposed in the receiving groove, and the second solar panel is electrically connected to the battery. Disposing the second solar panel in the receiving groove of the connecting portion can not only improve the light absorption effect of the second solar panel, but also use the second cover plate to achieve a high level of waterproof and dustproof for the second solar panel, improving the mechanical reliability of the wearable device.

[0022] In some embodiments, the opening of the receiving groove is arranged towards 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 can be understood as the side of the wearable device facing away from the user's body in the worn state. At this time, the second cover plate can be used as a part of the appearance surface of the wearable device, so that sunlight can directly irradiate on the second cover plate, and then penetrate the second cover plate to irradiate on the second solar panel in the receiving groove.

[0023] In some embodiments, the second cover plate is a convex lens, and the focal point of the second cover plate is located on the surface of the second solar panel. By using the principle of convex lens focusing, the solar energy density on the surface of the second solar panel can be effectively increased, which helps to improve the power generation of the second solar panel.

[0024] In some embodiments, the notch of the receiving groove is arranged towards 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 in the worn state. The end of the fixing band connected to the connecting part is at least partially opposite to the second cover plate. The outer side of the fixing band includes a light condensing layer, which can be used to reflect light to the second solar panel. That is to say, the second solar panel can receive solar energy through the light condensing layer.

[0025] In addition, the fixing band may further include a support layer, which is arranged on the inner side of the fixing band and fixedly connected to the light condensing layer to support and fix the light condensing layer through the support layer, thereby improving the structural strength of the fixing band.

[0026] In some embodiments, a second lead hole is provided in the housing, and both ends of the second lead hole communicate with the accommodating space and the receiving groove respectively. A third wire is arranged in the second lead hole, and both ends of the second wire are electrically connected to the second solar panel and the battery respectively, so that the second solar panel and the battery are electrically connected through the second wire.

[0027] In some embodiments, the wearable device may further include a third solar panel, which is made of a flexible material. The fixing band includes a first sub-fixing band and a second sub-fixing band, and the first sub-fixing band and the second sub-fixing band are detachably connected by a magnetic member. The third solar panel may be arranged on the outer side of the first fixing band, or may be arranged on the outer side of the second sub-fixing band, or may be respectively arranged on the outer sides of the first sub-fixing band and the second sub-fixing band. During the process of the user wearing the wearable device, the third solar panel can be directly exposed on the outer side of the wearable device, so the third solar panel can directly receive solar energy, and thus a better light absorption effect can be achieved. Moreover, by designing the first sub-fixing band and the second sub-fixing band to be detachably connected in a magnetic attraction manner, the outer regions of the first sub-fixing band and the second sub-fixing band can be fully utilized to arrange the third solar panel, thereby increasing the area of the third solar panel and further increasing the power generation of the third solar panel.

[0028] In some embodiments, the fixing band can be connected to the connecting part through a connecting member. The connecting member 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 by using this connecting member.

[0029] In some other embodiments, the inner side of the first sub-fixing band has a first groove, and the third solar panel is disposed in the first groove; a third lead hole is provided in the first sub-fixing band, a fourth lead hole is provided in the housing, the third lead hole communicates with the fourth lead hole, and the third lead hole communicates with the first groove, and the fourth lead hole communicates with the accommodating space; a fourth wire is provided in the third lead hole and the fourth lead hole, and the fourth wire is electrically connected to the third solar panel and the battery respectively; the outer side of the second sub-fixing band has a second groove, and the third solar panel is disposed in the second groove; a fifth lead hole is provided in the second sub-fixing band, a sixth lead hole is provided in the housing, the fifth lead hole communicates with the sixth lead hole, and the fifth lead hole communicates with the second groove, and the sixth lead hole communicates with the accommodating space; a fifth wire is provided in the fifth lead hole and the sixth lead hole, and the fifth wire is electrically connected to the third solar panel and the battery respectively.

[0061] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings. However, the exemplary embodiments can be implemented in various forms and should not be construed as being limited to the embodiments described herein. The same reference numerals in the drawings represent the same or similar structures, so their repeated description will be omitted. The words expressing positions and directions described in the embodiments of the present application are illustrative with reference to the drawings, but can be changed according to needs, and all changes are included in the protection scope of the present application. The drawings in the embodiments of the present application are only used to illustrate the relative positional relationship and do not represent the true proportion.

[0062] It should be noted that specific details are set forth in the following description to facilitate the understanding of the present application. However, the embodiments of the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the connotation of the embodiments of the present application. Therefore, the present application is not limited by the specific implementation manners disclosed below.

[0063] The wearable device provided by the embodiments of the present application can be a portable device, or can also be a device that can be integrated into the user's clothes or accessories. The wearable device has computing functions and can be connected to mobile phones and various terminal devices. Exemplarily, the wearable device can be a smart watch, a smart bracelet, a sports bracelet, a smart wristband, an accessory, etc.

[0064] Figure 1 The following is a schematic structural diagram of a wearable device 1000 provided by an embodiment of the present application. Figure 1 The wearable device 1000 in the illustrated embodiment is described by taking a smart watch as an example. The wearable device 1000 includes a main body 100 and a fixing band 200. The fixing band 200 is connected to both sides of the main body 100. The fixing band 200 can be wound around the user's wrist, arm, leg or other parts of the body to fix the wearable device 1000 to the user's body. Among them, the main body 100 can be approximately circular, rectangular or other polygonal shapes, and the present application does not make a display in this regard. Figure 1 One case where the main body 100 is circular is shown. It is easy to understand that in the case where 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 band 200 of the wearable device 1000 is the watch band.

[0065] In some embodiments, the main body 100 includes a housing 110 and a display screen 120. The housing 110 and the display screen 120 are fixedly connected and enclose to form an accommodation space. Among them, 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. Various functional modules and electronic components of the wearable device 1000 can be accommodated in the accommodation space formed by the display screen 120 and the housing 110, such as including but not limited to a circuit board, a processor, a battery, a charging management module, a communication module, a sensor module, an audio module, a speaker, a receiver, a microphone, etc., so that the wearable device 1000 can implement various functions.

[0066] In addition, in this embodiment, the wearable device 1000 can be divided into an inner side and an outer side. Among them, 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 can be understood as the side of the wearable device 1000 facing the user's body in the worn state. 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 can be understood as the side of the wearable device 1000 facing away from the user's body in the worn state. 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.

[0067] Among them, the communication module may include a mobile communication module and a wireless communication module. The mobile communication module may provide solutions for wireless communications such as 2G / 3G / 4G / 5G applied to the wearable device 1000. The wireless communication module may provide solutions for wireless communications applied to the wearable device 1000, including wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Bluetooth (BT), global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC), infrared technology (IR), etc. 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.

[0068] In some embodiments, the housing 110 may include a middle frame 1101 and a rear case (not shown in the figure). Along the thickness direction of the main body 100, the rear case is disposed 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 rear case. Among them, the side where the rear case is located may be the side in contact with the user when the wearable device 1000 is in a worn state. For example, when the wearable device 1000 is a smart watch, the outer surface of the rear cover may be in contact with the user's wrist. The outer surface of the rear case can be understood as the side facing the user's body and facing away from the external environment. In one implementation, the rear case and the middle frame 1101 may be integrally formed, that is, the rear case and the middle frame 1101 are a whole structure. In another implementation, the rear case and the middle frame 1101 are a split structure, and the rear case may be fixedly connected to the middle frame 1101 by means of bonding or the like.

[0069] In addition, the housing may further include a fixing ring 130. The fixing ring 130 is disposed around the display screen 120 in a circular shape, and is fixedly connected to the middle frame 1101. And at least a part of the fixing ring 130 covers one side surface of the display screen 120 facing away from the accommodation space, that is, partially covers the light-emitting side of the display screen 120. In one implementation, the fixing ring 130 and the middle frame 1101 may be an integrally formed structure. In another implementation, the fixing ring 130 and the middle frame 1101 may also be a split structure. Exemplarily, the fixing ring 130 and the middle frame 1101 may be adhesively fixed. The fixing ring 130 can be used as a part of the appearance of the main body 100. Taking the main body 100 as the watch head of a smart watch as an example, the fixing ring 130 can be regarded as the bezel in the watch head. On the one hand, the fixing ring 130 can play a role in protecting the display screen 120, reducing the risk of the edge of the display screen 120 being collided, scratched or damaged by other external factors. On the other hand, the fixing ring 130 can also improve the appearance quality of the wearable device 1000 by adopting different appearance designs, materials, etc. In addition, the surface of the fixing ring 130 can also be designed with characters such as scales, numbers or marks to facilitate the user to read the time.

[0070] In addition, the middle frame 1101 may be provided with an operation button 11011. The operation button 11011 can be electrically connected to the functional module housed in the accommodation space, and can perform specific functions in response to the rotation or pressing operation of the user, such as controlling the sliding of the display interface of the display screen 120, selecting the interactive control in the display interface of the display screen 120, etc.

[0071] Figure 2 It is a schematic structural diagram of the main body of the wearable device provided by the embodiment of the present application. Referring together Figure 1 and Figure 2 As shown, in the embodiment of the present application, a connection part 111 is provided on at least one side of the housing 110. The fixing band 200 can be fixedly connected to the housing 110 through the connection part 111. For example, in Figure 2 the shown embodiment, connection parts 111 may be respectively provided on opposite sides of the housing 110. In one implementation, the connection part 111 and the housing 110 may be an integrally formed structure. In another implementation, the connection part 111 and the housing 110 may be a split structure. The connection part 111 and the housing 110 may be fixedly connected, or may be detachably connected or movably connected. The present application does not limit this.

[0072] In addition, the fixing band 200 and the connection part 111 may be fixedly connected or may be detachably connected. The present application also does not limit this. In an example where the fixing band 200 and the connection part 111 adopt a detachable connection method, the user can replace the fixing band 200 according to the usage requirements or preferences, which helps to expand the application scenarios of the wearable device 1000.

[0073] In one implementation, there can be one fixing band 200. The two ends of the fixing band 200 are respectively connected to the two connecting parts 111 of the housing, so as to enclose a wearing space 300 with the housing 110. Exemplarily, the fixing band 200 can be made of an elastic material, and the elastic telescopic property of the fixing band 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.

[0074] In another implementation, the fixing band 200 includes two sub-fixing bands, which are defined as the first sub-fixing band 210 and the second sub-fixing band 220 respectively. Among them, one end of the first sub-fixing band 210 is connected to a connecting part 111 of the housing 110, and one end of the second sub-fixing band 220 is connected to another connecting part 111 of the housing 110. The first sub-fixing band 210 and the second sub-fixing band 220 are detachably connected. When the first sub-fixing band 210 and the second sub-fixing band 220 are connected, the first sub-fixing band 210, the second sub-fixing band 220 and the housing 110 enclose a wearing space 300, so that the wearable device can be worn on the user's body. Exemplarily, the first sub-fixing band 210 and the second sub-fixing band 220 can be detachably connected by a watch buckle or can be detachably connected by a magnetic attraction method. Both of these connection methods can adjust the wearing space 300 of the wearable device 1000, so that the wearable device 1000 meets the wearing needs of different users.

[0075] As mentioned above, a plurality of functional modules are integrated in the main body of the wearable device 1000, and almost all functional modules need to be driven by electricity to operate. Therefore, 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, and it is difficult to ensure that the wearable device 1000 has sufficient battery life solely relying on the primary battery capacity. Based on the above considerations, in the embodiments of the present application, the wearable device 1000 can also use solar power generation technology to supply power to its internal modules to improve the battery life. The following specifically describes the exemplary design of the solar technology applied to the wearable device 1000 in combination with specific embodiments.

[0076] Figure 3 For Figure 2 a schematic cross-sectional structure diagram at A-A in. Referring to Figure 2 and Figure 3 shown, in the embodiments 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, and along the direction away from the accommodation space 140, the display panel 121, the transparent substrate 122, the first solar panel 123, and the first cover plate 124 are stacked in sequence.

[0077] Among them, the first cover plate 124 is made of a transparent material. Exemplarily, the material of the first cover plate 124 can be glass. The first cover plate 124 can protect and dust-proof the first solar panel 123, the transparent substrate 122, and the display panel 121 inside it. The display panel 121 includes a display area 121a for displaying images or videos. In addition, the display panel 121 may further include a peripheral area 121b that surrounds the display area 121a and can be used to arrange traces. The display panel 121 can be a liquid crystal display (LCD), an organic light emitting diode (OLED), an active matrix organic light emitting diode (AMOLED), a flexible light emitting diode (FLED), a mini 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. Additionally, in some implementations, the display panel 121 can also integrate a touch function.

[0078] Please continue to refer to Figure 3 , in the embodiment of the present application, the transparent substrate 122 includes a first surface 1221 facing away from the accommodation space. The first surface 1221 includes a first region 1221a, which can be annularly arranged, and the projection of the first region 1221a on the first surface 1221 does not coincide with the display area 121a of the display panel 121. The first solar panel 123 is disposed within the first region 1221a. The first solar panel 123 can receive solar energy through the first cover plate 124 and convert the received solar energy into electrical energy. Exemplarily, the first solar panel 123 can be bonded within the first region 1221a by optical glue or other types of adhesives. Additionally, between the surface of the first solar panel 123 facing the first cover plate 124 and the first cover plate 124, and between the surface of the transparent substrate 122 facing the accommodation space 140 and the display panel 121, they can also be bonded and fixed by optical glue.

[0079] In this embodiment, the first solar panel 123 can have a relatively small thickness, so the first solar panel 123 will not overly occupy the thickness dimension of the display screen 120, which helps to reduce the occupied space of the display screen 120 in the wearable device. Exemplarily, the thickness of the first solar panel 123 can be less than or equal to 0.02 mm. Additionally, the first solar panel 123 can be a flexible gallium arsenide solar panel. The gallium arsenide solar material has a high solar energy conversion rate, so the first solar panel 123 prepared therefrom can achieve a relatively high power generation with a relatively limited size. Moreover, by designing the first solar panel 123 as a flexible structure, the reliability and shock resistance of the first solar panel 123 can be improved.

[0080] Please continue to refer to Figure 3 , in the embodiment of the present application, the first solar panel 123 is electrically connected to the battery 150 housed in the accommodation space 140 to deliver the converted electrical energy to the battery 150 and charge the battery 150. Therefore, for the wearable device provided in the embodiment of the present application, not only can the battery 150 be charged by the conventional charger charging method, but also the first solar panel 123 can be used to supplement electrical energy to the battery 150 in a sunny environment, and this solar charging method can be achieved during the user's wearing process, thereby improving both the charging convenience of the wearable device and effectively enhancing the battery life of the wearable device, so a better user experience can be brought to consumers. In addition, if the wearable device runs out of power during the user's wearing process, the battery 150 can be charged in time through the solar charging technology, thus ensuring the user's usage requirements at critical moments. For example, in an extreme outdoor environment and when the wearable device runs out of power, the user can use the electrical energy provided by the solar charging technology to make the wearable device send a distress signal to ensure their own life safety.

[0081] It should be noted that Figure 3 only exemplarily shows the battery 150 in the accommodation space 140. In actual implementation, the actual shape, actual size, actual position, and actual structure of the battery 150 are not limited by Figure 3 , and other functional modules of the wearable device can also be set at appropriate positions according to the internal layout and functional requirements of the accommodation space 140. For example, the space between the battery 150 and the display screen 120 can be used to arrange a circuit board and a battery holder.

[0082] In some embodiments, the wearable device further includes a photovoltaic controller (not shown in the figure), which can also be housed in the accommodation space 140. The input end of the photovoltaic controller is electrically connected to the first solar panel 123, and the output end of the photovoltaic controller is electrically connected to the battery 150. The photovoltaic controller can be used to convert the electrical energy output by the first solar panel 123 and then output it to the battery 150 to control parameters such as the charging current and voltage, ensuring the stability of charging.

[0083] In some embodiments, the first surface 1221 of the transparent substrate 122 may further include a second region 1221b. Along the radial direction of the transparent substrate 122, the second region 1221b is located inside the first region 1221a. It can also be understood that the second region 1221b and the first region 1221a are 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. In this way, in the direction from the first cover plate 124 to the accommodation space 140, the display area 121a of the display panel 121 can be completely exposed within the second region 1221b, enabling the light of the display area 121a of the display panel 121 to be emitted out of the display screen 120 successively through the transparent substrate 122 and the first cover plate 124. In this embodiment, since the first solar panel 123 has a certain thickness, there will be a certain gap between the region 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 an optical adhesive 125, which can not only improve the structural strength of the display screen 120 but also avoid the adverse effect of this gap on the display effect of the display screen 120.

[0084] In addition, in this embodiment, the projection of the display panel 121 on the first surface 1221 may coincide with the first surface 1221, that is to say, the radial dimension of the display panel 121 is basically equal to the radial dimension of the transparent substrate 122. At this time, the projection of the peripheral area 121b of the display panel 121 on the first surface 1221 may coincide with the first region 1221a, and the projection of the display area 121a of the display panel 121 on the first surface 1221 may coincide with the second region 1221b. In some other embodiments, the radial dimension of the display panel 121 may be slightly smaller than the radial dimension of the transparent substrate 122, and the projection of the display panel 121 on the first surface 1221 may also be entirely located within the second region 1221b, or the edge of the projection of the display panel 121 on the first surface 1221 may fall within the first region 1221a, or the radial dimension of the display panel 121 may also be slightly larger than the radial dimension of the transparent substrate 122, and the projection of the display panel 121 on the first surface 1221 may extend beyond the outer edge of the first region 1221a.

[0085] In the above several designs, by designing the transparent substrate 122 as a complete planar structure, the surface of the transparent substrate 122 facing the accommodation space 140 can be integrally attached to the display panel 121, and the thickness requirement for the transparent substrate 122 is relatively low. Therefore, the transparent substrate 122 can be designed to have a relatively small thickness, which helps to reduce the overall thickness of the display screen 120 and further reduces the occupied space of the display screen 120 in the wearable device. Exemplarily, the thickness of the transparent substrate 122 can be less than or equal to 0.05 mm.

[0086] During the assembly process of the display screen 120, the first solar panel 123 can be adhesively fixed in the first region 1221a of the first surface 1221 first, then the first surface 1221 and the first cover plate 124 are adhesively bonded into one body, and the gap between the two is filled with the optical glue 125. After that, the display panel 121 is adhesively 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 reception efficiency be improved, but also a high-level waterproof and dustproof effect can be achieved for the first solar panel 123, which helps to improve the overall mechanical reliability of the wearable device.

[0087] Figure 4 For Figure 2 a schematic cross-sectional structure diagram at A-A in Figure 4 As shown in the figure, in some other embodiments of the present application, the transparent substrate 122 can be annular. At this time, the entire area of the first surface 1221 of the transparent substrate 122 can be used as the first region 1221a. The projection of the display area 121a of the display panel 121 on the first surface 1221 is located in the hollow area inside the ring of the transparent substrate 122, so that the light of the display area 121a of the display panel 121 can be emitted outside the display screen through the hollow area of the transparent substrate 122 and the first cover plate 124 in sequence. Since the presence of the transparent substrate 122 and the first solar panel 123 will cause a certain gap to be 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 can be filled with the optical glue 125 to improve the structural strength of the display screen on the premise of ensuring the display effect of the display screen by using the filled optical glue 125. In addition, the size of the display panel 121 in this embodiment can be designed with reference to the foregoing embodiments and will not be repeated here.

[0088] Please refer to again Figure 3, in the embodiments of the present application, except for the first cover plate 124, there may be a first gap 112 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 disposed 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, so that the first solar panel 123 and the battery 150 are electrically connected 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 may be electrically connected to the photovoltaic controller and further electrically connected to the battery 150 through the photovoltaic controller.

[0089] In some embodiments, the number of the first solar panels 123 may be one. In this case, the shape of the first solar panel 123 may be annular, and the width of the ring of the first solar panel 123 (hereinafter referred to as "ring width") may be substantially the same as or slightly smaller than the ring width of the first region 1221a of the transparent substrate 122, so as to improve the area of the first solar panel 123 as much as possible without affecting the display effect of the display area 121a of the display panel 121, and further improve the power generation of the first solar panel 123.

[0090] In some other embodiments, the number of the first solar panels 123 may be multiple, for example Figure 5a and Figure 6a shown, Figure 5a and Figure 6a respectively show partial plane structure schematic diagrams of two display screens 120 provided by the embodiments of the present application. Among them, Figure 5a shows an example in which the number of the first solar panels 123 is four, Figure 6a shows an example in which the number of the first solar panels 123 is eight. In the case where the first solar panels 123 are multiple, the multiple first solar panels 123 may be arranged at intervals along the circumferential direction of the transparent substrate 122 in the first region 1221a. The first solar panel 123 may be fan-shaped, and the ring width of the first solar panel 123 may be slightly smaller than or equal to the ring width of the first region 1221a of the transparent substrate 122. In addition, the sizes of the multiple first solar panels 123 may be the same, which is convenient for controlling the sizes of the respective first solar panels 123 and helps to simplify the manufacturing process and manufacturing cost of the display screen 120.

[0091] Figure 5b and Figure 6b respectively show partial plane structure schematic diagrams of two first cover plates provided by the embodiments of the present application. Referring together to Figure 5a and Figure 5b , Figure 6a and Figure 6bAs shown, in order to prevent the gaps between adjacent first solar panels 123 from being exposed on the light-emitting side of the display screen 120 through the first cover plate 124, in some implementations, the surface of the first cover plate 124 facing the accommodation space 140 has an ink layer 1241. 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 coincide 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's reception of light, thereby improving the appearance effect of the wearable device. In addition, the projection of the ink layer 1241 on the first surface does not coincide with the projection of the display area of the display panel on the first surface, so as to avoid the ink layer 1241 affecting the display effect of the display screen. It should be understood that in the example where the first solar panel 123 is in a whole-ring shape, the ink layer can be omitted.

[0092] In some embodiments, adjacent first solar panels 123 can be electrically connected. Traces 12211 are provided in the region of the first area 1221a corresponding to the gaps between two adjacent first solar panels 123. These traces 12211 can be respectively electrically connected to two circumferentially adjacent first solar panels 123. Or it can be understood that two adjacent first solar panels 123 can be electrically connected through the traces 12211 in the corresponding gaps. In this way, multiple first solar panels 123 can be connected in series in sequence. The two first solar panels 123 located at the head and the end among the multiple serially connected first solar panels 123 can be electrically connected to the battery, so as to transmit all the electric energy generated by the multiple first solar panels 123 to the battery for storage.

[0093] Among them, each trace 12211 can be formed in the first area 1221a by printing to simplify the manufacturing and assembly processes of the display screen 120. In addition, since the gaps between adjacent first solar panels 123 have been blocked by the ink layer 1241, the traces 12211 located in each gap can also be covered by the ink layer 1241 and will not be exposed on the light-emitting side of the display screen 120.

[0094] In some other embodiments, multiple first solar panels 123 can be connected in parallel. In this case, adjacent first solar panels 123 do not need to be electrically connected through traces 12211. Each first solar panel 123 is respectively electrically connected to the battery, so that the electric energy generated by each first solar panel 123 is respectively transmitted to the battery for storage.

[0095] In the embodiment of the present application, the first solar panel 123 can be cut from a whole solar panel. By adopting a multi-segment design for the first solar panels 123 in the first region 1221a, the area occupied by each first solar panel 123 in the whole solar panel is relatively small, and the arrangement of the cutting lines of each first solar panel 123 can be relatively dense. Therefore, the utilization rate of the whole solar panel can be effectively improved, which helps to reduce the manufacturing cost of the display screen 120.

[0096] Figure 7 FIG. is a schematic structural diagram of the light-emitting side of the display screen 120 of the wearable device provided by the embodiment of the present application. Refer to Figure 7 As shown, since the gallium arsenide solar material itself has a metallic texture, when viewed from the light-emitting side of the display screen 120, the first solar panel 123 can achieve a visual effect similar to that of a metal decorative ring. 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, so as to cooperate 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 respectively correspond to the scales 0, 10, 20, 30, 40, and 50 on the fixing ring 130.

[0097] Figure 8 FIG. Figure 2 is another schematic cross-sectional structure diagram taken along line A-A in Figure 8 As shown, in the embodiment of the present application, the fixing ring 130 is made of a transparent material. Exemplarily, the fixing ring 130 can specifically be Kunlun glass, sapphire, or other materials with high transmittance, so as to take into account both high appearance value and high strength characteristics. The wearable device may further include a solar film 400, and the solar film 400 is disposed on the inner surface of the fixing ring 130. Therefore, the solar film 400 can receive solar energy through the transparent fixing ring 130 and convert the received solar energy into electric energy. Here, 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 a partial appearance surface of the main body 100, that is, the surface exposed outside the main body 100, and the inner surface of the fixing ring 130 can be understood as the surface not exposed outside the main body 100. Exemplarily, the solar film 400 can be formed on the inner surface of the fixing ring 130 by an electroplating process.

[0098] The solar film 400 is electrically connected to the battery 150 contained in the accommodating space 140 to transmit the converted electric energy to the battery 150 to charge the battery 150. Similarly, the solar film 400 can also be electrically connected to the battery 150 through a photovoltaic controller to convert the electric energy output by the solar film 400 through the photovoltaic controller and then output it to the battery 150 to ensure the stability of charging. In this embodiment, the wearable device can be charged by conventional charging methods, or the solar film 400 can be used to supplement the battery with electric energy in a sunlight environment, thereby effectively improving the endurance of the wearable device.

[0099] It should be noted that Figure 8 The battery 150 in the accommodating space is only shown as an 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 a circuit board and a battery holder.

[0100] Figure 9 for Figure 8 The enlarged image of the C in the middle. Please refer to Figure 8 and Figure 9 As shown, 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 is disposed around 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, and 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 the third inner surface 1322 is arranged around the peripheral side of the display screen 120. The solar film 400 may be arranged on at least one inner surface of the first inner surface 1311, the second inner surface 1321, and the third inner surface 1322, for example Figure 9 An example is shown in which the first inner surface 1311 , the second inner surface 1321 and the third inner surface 1322 are all provided with a 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 .

[0101] In one implementation, the middle frame 1101 includes a first end face 113 facing the display screen 120, and the display screen 120 is fixedly connected to the first end face 113. For example, the first cover plate 124 of the display screen 120 can be used to fixedly connect to the first end face 113 of the middle frame 1101, and other layer structures of the display screen 120 including the display panel can be located inside the middle frame 1101. Exemplarily, the display screen 120 and the first end face 113 can be fixedly connected by adhesive. Along the radial direction of the display screen 120, the edge of the first end face 113 extends beyond the edge of the display screen 120, or it can be understood that the projection edge of the display screen 120 on the first end face 113 is spaced from the edge of the first end face 113. The second inner surface 1321 of the fixing ring 130 is connected to the area where the first end face 113 extends beyond the edge of the display screen 120, so as to dispose the solar film 400 provided on the second inner surface 1321 between the second inner surface 1321 and the first end face 113.

[0102] In some embodiments, the edge of the side surface of the display screen 120 facing away from the accommodating space 140 has a first sinking step 1242, and the first inner surface 1311 can be fixed to the step surface of the first sinking step 1242, so as to dispose the solar film 400 provided on the first inner surface 1311 between the first inner surface 1311 and the step surface of the first sinking step 1242. The first inner surface 1311 and the step surface of the first sinking step 1242 can be sealed by a waterproof adhesive 1243, and the waterproof adhesive 1243 can wrap the solar film 400 on the first inner surface 1311 to improve the waterproof and dustproof effect on the solar film 400. In one implementation, the surface of the top wall 131 facing away from the step surface of the first sinking step 1242 is flush with the light-emitting side surface of the display screen 120, so that the appearance surface of the wearable device body presents a flat appearance effect.

[0103] The edge of the first end face 113 can have a second sinking step 1131, and the second inner surface 1321 can be fixed to the step surface of the second sinking step 1131. Correspondingly, the solar film 400 on the second inner surface 1321 is disposed between the second inner surface 1321 and the step surface of the second sinking step 1131. At this time, the third inner surface 1322 partially surrounds the circumferential side of the display screen 120 and partially surrounds the side surface of the second sinking step 1131. Similarly, the second inner surface 1321 and the step surface of the second sinking step 1131 can be sealed by a waterproof adhesive 1132, and the waterproof adhesive 1132 can wrap the solar film 400 on the second inner surface 1321 to improve the waterproof and dustproof effect on the solar film 400.

[0104] Among them, 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. 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 gaps between the top wall 131 and the side surface of the first sunken step 1242, between the first inner surface 1311 and the step surface of the first sunken step 1242, between the third inner surface 1322 and the peripheral side of the display screen 120, between the third inner surface 1322 and the side surface of the second sunken step 1131, and between the second inner surface 1321 and the step surface of the second sunken step 1131 respectively.

[0105] Please refer to again Figure 8 , in some embodiments of the present application, the solar film 400 and the battery 150 can be electrically connected through the second wire. In a specific implementation, the second wire can be arranged in the existing gaps between the various structures inside the main body, or lead holes can be additionally opened to arrange the second wire. The present application does not limit this, as long as the second wire can electrically connect the solar film and the battery.

[0106] For example, in one implementation, a first lead hole 114 can be provided in the housing 110, and the first lead hole 114 communicates with the accommodation space 140. Exemplarily, one end of the first lead hole 114 is provided on the first end face 113 of the middle frame 1101, and the other end of the first lead hole 114 is provided on the inner wall surface of the middle frame 1101. The second wire 170 is arranged in the first lead hole 114, 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, so that the solar film 400 and the battery 150 are electrically connected through the second wire 170. This design is the way of additionally opening lead holes as described above.

[0107] In another implementation, there is a second gap 11012 between the middle frame 1101 and the display screen 120. The second wire 170 is arranged 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, so that the solar film 400 and the battery 150 are electrically connected through the second wire 170. This design is the way of using the existing gaps between the various structures as described above.

[0108] In some embodiments, the solar film 400 can include multiple segments 410, for example Figure 10a , Figure 10b , Figure 10c , Figure 10d as shown, Figure 10a ,Figure 10b , Figure 10c , Figure 10d respectively show schematic plan views of four fixing rings 130 provided in embodiments of the present application. Among them, Figure 10a , Figure 10b , Figure 10c show exemplary designs in which, when the fixing ring 130 is a circular ring, the solar film 400 includes two segments 410, four segments 410, and six segments 410. Along the circumferential direction of the fixing ring 130, the respective segments 410 are spaced apart on the inner surface of the fixing ring 130, and the intervals between the respective segments 410 may be equal or unequal, and the present application does not make any limitation thereto. Figure 10d shows an example in which, when the fixing ring 130 is a rectangular ring, the solar film 400 includes two segments 410. The two segments 410 may be respectively disposed 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 may be respectively disposed 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, and so on. Figure 10d The example in

[0109] is the case where the two segments 410 are respectively disposed on the left and right sides of the fixing ring 130.

[0110] In addition, in embodiments of the present application, the respective segments 410 may be connected in parallel, and each segment 410 is respectively electrically connected to a battery, so that the electric energy generated by each segment 410 is respectively transmitted to the battery for storage.

[0111] In one implementation, the functional film 500 may be a conductive film, and the conductive film may also be formed on the inner surface of the fixing ring 130 by an electroplating process. The use of the conductive film can enable the fixing ring to achieve an antenna function, and further enable the wearable device to achieve a communication function.

[0112] In another implementation, the functional film 500 may also be a decorative film, and the decorative film may also be formed on the inner surface of the fixing ring 130 by an electroplating process. By selecting a suitable decorative film to match with the solar film 400, a good appearance effect can be achieved on the outer surface of the fixing ring 130.

[0113] In the case where the solar film 400 includes a plurality of segments 410 and the functional film 500 is plural, along the circumferential direction of the fixing ring 130, the plurality of segments 410 and the plurality of functional films 500 are alternately arranged in sequence. This design can make the outer surface of the fixing ring 130 present an alternating color change, bringing a good visual experience to the user.

[0114] Figure 11 This is a partial exploded structural view of the main body 100 of the wearable device provided by the embodiment of the present application. Refer to Figure 11 As shown, as described above, the housing 110 includes at least one connecting portion 111 for connecting with the fixing belt. In the 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. Exemplarily, glue can be used for sealing between the second cover plate 700 and the notch of the receiving groove 1111 to improve the waterproof and dustproof effect on the second solar panel 600.

[0115] In addition, the second cover plate 700 is made of a transparent material. In this way, the second solar panel 600 can receive solar energy through the transparent second cover plate 700 and convert the received solar energy into electric energy. The second cover plate 700 can be Kunlun glass. By using the characteristics of high transmittance, high strength, and anti-drop of Kunlun glass, a better protection effect can be achieved on the second solar panel 600 in the receiving groove 1111. In addition, since the receiving groove 1111 is formed in the connecting portion 111 of the housing 110 by a subtractive process, the weight of the whole machine is reduced to a certain extent, which helps to improve the user experience.

[0116] The second solar panel 600 can be a flexible gallium arsenide solar panel. Therefore, the second solar panel 600 can not only achieve a high solar energy conversion rate but also have reliable impact resistance. The second solar panel 600 is electrically connected to the battery housed in the accommodation space to deliver the converted electric energy to the battery for charging the battery. Similarly, the second solar panel 600 can also be electrically connected to the battery through a photovoltaic controller to output the electric energy output by the second solar panel 600 to the battery after power conversion through the photovoltaic controller, ensuring the stability of charging. In this embodiment, the wearable device can be charged either by a conventional charging method or by using the second solar panel 600 to supplement electric energy to the battery in a sunny environment, thereby effectively improving the battery life of the wearable device.

[0117] Continue to refer to Figure 11 , in this embodiment, the notch of the receiving groove is arranged towards the outside of the wearable device. At this time, the second cover plate 700 can be used as a part of the appearance surface of the wearable device. Therefore, sunlight can directly irradiate 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.

[0118] In one implementation, the second solar panel 600 can be fixed to the bottom of the receiving groove 1111. The bottom of the receiving groove 1111 is substantially parallel to the second cover plate 700, and the depth of the receiving groove 1111 is relatively small. After the second solar panel 600 is disposed in the receiving groove 1111, the second solar panel 600 can be attached to the surface of the second cover plate 700 facing the receiving groove 1111. This can shorten the propagation path of sunlight, thereby reducing the energy loss of sunlight and improving the solar energy reception efficiency of the second solar panel 600.

[0119] Figure 12 For Figure 2 a schematic cross-sectional structure view at B-B in. Refer to Figure 12 As shown, in the embodiment of the present application, the second cover plate 700 is a convex lens structure. At this time, the receiving groove 1111 has a relatively large depth. After the second solar panel 600 is disposed 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 focal point of the second cover plate 700 can fall on the surface of the second solar panel 600, thereby effectively increasing the solar energy density on the surface of the second solar panel 600, enabling the second solar panel 600 to achieve a relatively high power generation with a relatively limited size.

[0120] 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. Exemplarily, the second solar panel 600 and the bottom of the receiving groove 1111 can be adhesively fixed.

[0121] In another implementation, the receiving groove 1111 can also be a through groove, or it can be understood that the receiving groove 1111 penetrates 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. At this time, in order to fix 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. Exemplarily, the second solar panel 600 and the support plate 11111 can be adhesively fixed, and the support plate 11111 and the groove wall of the receiving groove 1111 can be sealed by dispensing glue.

[0122] In addition, in Figure 11 and Figure 12In the two embodiments shown, the housing 110 may have a second lead hole 115, and both ends of the second lead hole 115 communicate with the accommodation space 140 and the accommodation groove 1111 respectively. A third wire 180 is disposed 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, so that the second solar panel 600 and the battery 150 are electrically connected 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 may be electrically connected to the photovoltaic controller and further electrically connected to the battery 150 through the photovoltaic controller.

[0123] Figure 13 FIG. is a partial structural cross-sectional view of another wearable device 1000 provided by an embodiment of the present application. Figure 14 is Figure 13 an enlarged view of the portion at D in Figure 13 and Figure 14 As shown, in this embodiment, the notch of the accommodation groove 1111 is arranged facing the inner side of the wearable device. At this time, the end of the fixing band 200 connected to the connecting portion 111 is at least partially opposite to the second cover plate 700. The outer side of the fixing band 200 includes a light condensing layer 230. After the light irradiates the light condensing layer 230, it can be reflected in the light condensing layer 230, and after being reflected by the light condensing layer 230, it penetrates the second cover plate 700 and enters the accommodation groove 1111, and is received by the second solar panel 600 in the accommodation groove 1111. Exemplarily, the material of the light condensing layer 230 may be polydimethylsiloxane (PDMS). Wherein, the outer side of the fixing band 200 can be understood as the side where the fixing band 200 forms the outer side of the wearable device 1000, that is, the side of the fixing band 200 facing the external environment.

[0124] In addition, in this embodiment, the inner side of the fixing band 200 further includes a support layer 240, and the support layer 240 is fixedly connected to the light condensing layer 230. Exemplarily, the support layer 240 and the light condensing layer 230 may be fixedly bonded. The material of the support layer 240 is not limited. For example, it may be rubber, leather, nylon, etc., and the present application does not limit this. Wherein, the inner side of the fixing band 200 can be understood as the side where the fixing band 200 forms the inner side of the wearable device 1000, that is, the side of the fixing band 200 facing away from the external environment.

[0125] In a case where the housing 110 includes two connecting portions 111, and the two connecting portions 111 are respectively provided with receiving grooves 1111 for receiving the second solar panel 600, in one implementation, the wearable device 1000 includes a fixing band 200, and all regions on the outer side of the fixing band 200 can be covered by the light condensing layer 230, so as to respectively reflect light into 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 band and a second sub-fixing band, and the light condensing layer 230 can be provided on the outer side of the first sub-fixing band and the outer side of the second sub-fixing band, so as to respectively reflect light into the second solar panels 600 in the receiving grooves 1111 of the two connecting portions 111.

[0126] Figure 15 FIG. is a partial structural cross-sectional view of another wearable device 1000 provided by an embodiment of the present application. Refer to Figure 15 As shown, in the embodiment of the present application, the wearable device 1000 includes a first sub-fixing band 210, a second sub-fixing band 220, and a third solar panel 800. The third solar panel 800 is made of a flexible material. The third solar panel 800 can be disposed on the outer side of the first sub-fixing band 210, or disposed on the outer side of the second sub-fixing band 220. Alternatively, the third solar panel 800 can be respectively disposed on the outer sides of the first sub-fixing band 210 and the second sub-fixing band 220. During the process of the user wearing the wearable device 1000, the third solar panel 800 can be exposed to light, so the third solar panel 800 can directly receive solar energy and convert the received solar energy into electric energy.

[0127] Exemplarily, the third solar panel 800 can be a flexible gallium arsenide solar panel. Therefore, the third solar panel 800 can not only achieve a high solar energy conversion rate, but also has reliable impact resistance. The third solar panel 800 is electrically connected to the battery 150 housed in the accommodation space 140 to deliver 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 as to output the electric energy output by the third solar panel 800 to the battery 150 after power conversion through the photovoltaic controller to ensure the stability of charging. In this embodiment, the wearable device 1000 can be charged by a conventional charging method, or the third solar panel 800 can be used to supplement electric energy to the battery 150 in a sunny environment, thereby effectively improving the battery life of the wearable device 1000.

[0128] It should be noted that Figure 15Only the battery 150 within the accommodation space 140 is exemplarily shown herein. In specific implementation, other functional modules of the wearable device 1000 may also be arranged at appropriate positions according to the internal layout and functional requirements of the accommodation space 140. For example, the space between the battery 150 and the display screen 120 can be used to arrange a circuit board and a battery bracket.

[0129] In some embodiments, when the third solar panel 800 is provided on the first sub-fixing band 210, a first groove 211 is formed on the side of the first sub-fixing band 210 facing away from the wearing space 300. The first groove 211 can extend along the length direction of the first sub-fixing band 210, and the third solar panel 800 of the first sub-fixing band 210 is fixed within the first groove 211. Exemplarily, the third solar panel 800 of the first sub-fixing band 210 can be adhesively fixed within the first groove 211, and the edge of the third solar panel 800 and the groove wall of the first groove 211 can be sealed by dispensing glue. Similarly, when the third solar panel 800 is provided on the second sub-fixing band 220, a second groove is formed on the side of the second sub-fixing band 220 facing away from the wearing space 300. The second groove extends along the length direction of the second sub-fixing band 220, and the third solar panel 800 of the second sub-fixing band 220 is fixed within the second groove. Exemplarily, the third solar panel 800 of the second sub-fixing band 220 can be adhesively fixed within 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.

[0130] Please continue to refer to Figure 15 , in some embodiments, the first sub-fixing band 210 and the second sub-fixing band 220 can be respectively connected to the corresponding connection parts through connectors. For example, the first sub-fixing band 210 can be connected to a connection part 111 of the housing 110 through a first connector 250, and the second sub-fixing band 220 can be connected to another connection part 111 of the housing 110 through a second connector 260. Exemplarily, both the first connector 250 and the second connector 260 can be spring bars. Wherein, each connector includes a first end and a second end. For the first connector 250, when the third solar panel 800 is provided on the first sub-fixing band 210, the first end of the first connector 250 can be electrically connected to the battery 150, and the second end of the first connector 250 can be electrically connected to the third solar panel 800 of the first sub-fixing band 210; for the second connector 260, when the third solar panel 800 is provided on the second sub-fixing band 220, the first end of the second connector 260 can be electrically connected to the battery 150, and the second end of the second connector 260 can be electrically connected to the third solar panel 800 of the second sub-fixing band 220.

[0131] Alternatively, in some other embodiments, when the third solar panel 800 is provided on the first sub-fixed band 210, a third lead hole 212 may be provided in the first sub-fixed band 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. The fourth lead hole 116 communicates with the accommodation space 140 of the housing 110. A fourth wire 190 is provided 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, so that the third solar panel 800 in the first groove 211 is electrically connected to the battery 150 through the fourth wire 190.

[0132] When the third solar panel 800 is provided on the second sub-fixed band 220, a fifth lead hole may be provided in the second sub-fixed band 220, and a sixth lead hole may be provided in the housing 110. The fifth lead hole communicates with the sixth lead hole, and the fifth lead hole communicates with the second groove. The sixth lead hole communicates with the accommodation space 140 of the housing 110. A fifth wire is provided in the fifth lead hole and the sixth lead hole. 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, so that the third solar panel 800 in the second groove is electrically connected 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 may be electrically connected to the photovoltaic controller and further electrically connected to the battery 150 through the photovoltaic controller.

[0133] In the embodiments of the present application, the first sub-fixed band 210 and the second sub-fixed band 220 are detachably connected by a magnetic attraction method. Exemplarily, a first magnetic member is embedded in the first sub-fixed band 210, and a second magnetic member is embedded in the second sub-fixed band 220. When the first sub-fixed band 210 and the second sub-fixed band 220 overlap each other, the first magnetic member and the second magnetic member can be magnetically attracted to connect the first sub-fixed band 210 and the second sub-fixed band 220.

[0134] In addition, there may be multiple first magnetic members, and the multiple first magnetic members are arranged in sequence along the length direction of the first sub-fixing band 210. Similarly, there may also be multiple second magnetic members, and the multiple second magnetic members are arranged in sequence along the length direction of the second sub-fixing band 220. Through this design, the first sub-fixing band 210 and the second sub-fixing band 220 can be connected by the magnetic members in their respective overlapping regions at different overlapping lengths, so that the wearable device 1000 can adjust the size of the wearing space 300 to meet the wearing needs of different users. And, taking the example that the first sub-fixing band 210 overlaps on the second sub-fixing band 220 when the first sub-fixing band 210 and the second sub-fixing band 220 are connected, as the overlapping length of the first sub-fixing band 210 and the second sub-fixing band 220 changes, the size of the area exposed by the third solar panel 800 on the second sub-fixing band 220 also changes accordingly, and thus the power generation amount of the third solar panel 800 on the second sub-fixing band 220 can be changed.

[0135] In this embodiment, the first sub-fixing band 210 and the second sub-fixing band 220 are designed to be connected in a magnetic attraction manner. Since there is no need to punch holes in the first sub-fixing band 210 or the second sub-fixing band 220, the area on the side of the first sub-fixing band 210 and the second sub-fixing band 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 amount of the third solar panel 800.

[0136] The above embodiments respectively introduce several solar charging solutions for setting solar panels or solar films on the display screen, fixing ring, housing, and fixing band of the wearable device. Although the specific implementation forms of each solution are slightly different, they all have the advantages of high solar conversion efficiency, good mechanical reliability, support for high-level waterproof and dustproof, and saving the internal stacking space of the whole machine. 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 can be combined with one or more other solutions and applied to the wearable device. That is to say, the wearable device can have at least one of the above-mentioned first solar panel, second solar panel, third solar panel, and solar film and its related design, so as to effectively improve the battery life of the wearable device.

[0137] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
