[0008] a supporting frame, rotatably connected to the frame and located on a side of the frame facing toward or away from the wearer, wherein the solar charging element is mounted on the supporting frame;

[0009] The support frame is used to drive the solar charging element to flip along the first direction or the second direction under the action of an external force, so that the solar charging element is arranged at an angle with the frame, or the solar charging element covers the side of the frame facing toward or away from the wearer;

[0034] like Figure 1 As shown, an embodiment of the present application provides a charging component 1, which is applied to a wearable device 100. The wearable device 100 is a smart device with a display function such as AR, VR or XR. The charging component 1 can use solar energy to charge the wearable device 100. The wearable device 100 can be smart glasses such as AR glasses and VR glasses. Specifically, the wearable device 100 includes a charging component 1, a frame 2, a controller (not shown) and an energy storage element (not shown). The controller and the energy storage element are both arranged in the frame 2; wherein, the charging component 1 includes a solar charging element 10 and a supporting frame 20, the solar charging element 10 and the energy storage element are electrically connected to the controller, and the supporting frame 12 is rotatably connected to the frame 21 and is located on the side of the frame 21 facing or away from the wearer; the solar charging element 11 is installed on the supporting frame 12; the supporting frame 20 is used to drive the solar charging element 10 to flip along the first direction or the second direction under the action of external force, so that the solar charging element 10 is set at an angle to the frame 2, or the solar charging element 10 covers the side of the frame 2 facing or away from the wearer; the first direction and the second direction are opposite.

[0035] like Figure 1 As shown, in one embodiment of the present application, a first mounting hole (not shown) is provided on the frame 2, and the inner side of the frame 2 is configured to be worn by the user; the wearable device also includes a display lens 3, which is used to display images, and the display lens 3 is installed in the first mounting hole of the frame 2 through a mounting portion (not shown); optionally, the display lens 3 is a resin lens containing a waveguide.

[0036] In this embodiment, the charging assembly 1 is used in a wearable device 100 such as AR glasses or VR glasses. Based on the principle of solar charging and related charging and discharging technologies, the controller of the wearable device 100 can process the electrical signals transmitted from the solar charging element 10 and manage the charging and discharging of the energy storage element. The energy storage element of the wearable device 100 can store and release electrical energy. In the charging assembly 1, the solar charging element 10 is used to receive solar energy and convert it into electrical energy. The charging assembly 1 converts light energy into electrical energy to charge the wearable device 100. This allows for continuous power supply to the wearable device 100 without the need for an external power source, eliminating the need to carry a charging cable or charging box, making charging convenient.

[0037] Furthermore, the charging assembly 1 is provided with a support frame 20 for mounting and supporting the solar charging element 10, thereby improving the installation stability of the solar charging element 10. The support frame 20 is rotatably connected to the frame 2, so that the support frame 20 can drive the solar charging element 10 to flip in the first direction or the second direction under the action of an external force. Furthermore, the solar charging element 10 is mounted on the side of the frame 2 away from the wearer via the support frame 20, thereby facilitating the solar charging element 10 to receive sunlight. Thus, when the wearable device 2 is worn and used, the support frame 20 can be flipped so that the solar charging element 10 is positioned at an angle to the frame 2, so that the side of the solar charging element 10 away from the frame 2 faces the sun. This facilitates the solar charging element 10 to receive solar energy and continuously charge the wearable device 100. The wearable device 100 can then continue to be worn and used during the charging process, thereby extending the use time of the wearable device 100 and improving the user experience.

[0038] The first direction may be understood as a direction away from the lens frame 2 , and the second direction may be understood as a direction close to the lens frame 2 .

[0039] It can be seen that, compared to installing the solar charging element 10 on the side of the frame 2 facing the wearer, the solar charging element 10 is installed on the side of the frame 2 facing away from the wearer via the support frame 20. This allows the wearable device 100 to be worn without removing the wearable device 100. The support frame 20 can be flipped along the first direction, thereby flipping the solar charging element 10, so that the solar charging element 10 is arranged at an angle with the frame. It should be noted that when the solar charging element 10 is installed on the side of the frame 2 facing the wearer and the wearable device 100 needs to be charged, the user can first remove the wearable device 100, then flip the support frame 20 along the first direction to flip the solar charging element 10. Specifically, the support frame 20 can be flipped to the side of the frame 2 facing away from the wearer, so that the solar charging element 10 forms an angle with the frame 2, and then the wearable device 100 can be worn again, which can also achieve continued wear and use of the wearable device 100 during the charging process.

[0040] Combine Figure 1 In some embodiments, the solar charging element 10 may be a semi-transparent solar lens or a solar panel, such as a miniaturized, high-efficiency flexible solar panel. Specifically, the solar charging element 10 may be an amorphous silicon (a-Si) flexible film or a copper indium gallium selenide (CIGS) flexible film, capable of receiving solar energy and converting it into electrical energy. Specifically, the energy storage element may be a supercapacitor or a micro lithium battery, capable of storing electrical energy and providing electrical energy to electrical components in the wearable device 100. In some embodiments, the solar charging element 10 is electrically connected to the controller via a wiring element (not shown), and the energy storage element is electrically connected to the controller via a wiring element. Specifically, the wiring element may be a flexible printed circuit (FPC) or a transparent indium tin oxide (ITO) conductive film.

[0041] Combine Figure 1 In another embodiment of the present application, the mirror frame 2 is further provided with a buck regulator (not shown) and a charging management chip (not shown), and the buck regulator and the charging management chip are electrically connected to the controller and the solar charging element 10 through wiring elements respectively.

[0042] The buck regulator is used to convert the higher voltage generated by the solar cell into a stable voltage suitable for storage and use; the charging management chip is used to control the charging process of electrical energy to the energy storage element to ensure safe and efficient charging.

[0043] Combine Figure 1 In some application scenarios, when a user wears the wearable device 100 and walks in the sun, and the frame 2 is worn on the user's head, the solar charging element 10 covers the side of the frame 2 away from the human eye, and the solar charging element 10 is located in front of the human eye. In this way, when charging with the charging component 1, the user can flip the supporting frame 20 to form an angle between the solar charging element 10 and the frame 2, so that the side of the solar charging element 10 away from the frame 2 faces the sky and receives sunlight. In this way, when the user wearing the wearable device 100 is walking, the charging component 1 can also continue to charge the wearable device 100.

[0044] Combine Figure 1 In some embodiments, a plurality of solar charging elements 10 are mounted on the carrier 20. The plurality of solar charging elements 10 receive solar energy together, which can improve charging efficiency and save charging time.

[0045] like Figure 1 and Figure 3As shown, in some embodiments, the support frame 20 includes a first support portion 201 and a second support portion 202 , and the first support portion 201 and the second support portion 202 are both mounted with a solar charging element 10 , and the first support portion 201 and the second support portion 202 are rotatably connected to the mirror frame 2 .

[0046] like Figure 3 and Figure 6 As shown, in some embodiments, a second mounting hole 20 a is defined on the first supporting portion 201 and / or the second supporting portion 202 , and the solar charging element 10 is received in the first supporting portion 201 and / or the second supporting portion 202 through the second mounting hole 20 a .

For example, the first supporting portion 201 and the second supporting portion 202 can both be mirror structures made of glass or resin. Specifically, the first supporting portion 201 and the second supporting portion 202 each have a first surface (not shown) facing the frame 2 and a second surface (not shown) facing away from the frame 2, and the solar charging element 10 is connected to the first surface or the second surface. In some embodiments, the solar charging element 10 is attached to the first surface or the second surface using adhesive. In other embodiments, the solar charging element 10 is magnetically connected to the first surface or the second surface.

[0048] Combine Figure 3 In some embodiments, the first supporting portion 201 and the second supporting portion 202 each include two fixing frames (not shown).

The multiple snap-fitting portions are spaced apart around the centerline of the fixing frames. The solar charging element 10 is sandwiched between the two fixing frames, and the multiple snap-fitting portions are snap-fitted to the edges of the solar charging element 10 to secure the solar charging element 10 between the two fixing frames. Exemplarily, the snap-fitting portions are buckles.

[0049] like Figure 3 As shown, in some embodiments, the supporting frame 20 further includes a first connecting portion 203 , and the first connecting portion 203 is used to connect the first supporting portion 201 and the second supporting portion 202 .

[0050] Combine Figure 1 In some embodiments, the charging assembly 1 further includes at least one hinge mechanism 30, with both ends of the hinge mechanism 30 connected to the support frame 20 and the frame 2, respectively, so that the support frame 20 can rotate relative to the frame 2, thereby driving the solar charging element 10 to flip relative to the frame 2 in the first direction or the second direction. Exemplarily, the hinge mechanism 30 can be a hinge.

[0051] like Figure 2 As shown, in some embodiments, each hinge mechanism 30 includes a first hinge member 31 and a second hinge member 32, and the first hinge member 31 and the second hinge member 32 are rotatably connected. One of the first hinge member 31 and the second hinge member 32 is provided on the supporting frame 20 and the other is provided on the frame 2, so that the supporting frame 20 can rotate relative to the frame 2.

[0052] like Figure 3 and Figure 4 As shown, in one embodiment of the present application, in the same hinge mechanism 30, the number of the second hinges 32 is two, and the two second hinges 32 are respectively located on both sides of the first hinge 31. The same hinge mechanism 30 also includes a hinge shaft 33, and the first hinge 31 and the second hinge 32 are hinged through the hinge shaft 33. Specifically, the hinge shaft 33 passes through the first hinge 31, and the two ends of the hinge shaft 33 are respectively connected to the two second hinges 32, so that the second hinge 32 rotates around the hinge shaft 33 relative to the first hinge 31. In the length direction of the hinge shaft 33, the first hinge 31 and the second hinge 32 are spaced apart, the first hinge 31 is provided on the frame 2, and the second hinge 32 is provided on the carrier 20.

[0053] like Figure 4 As shown, in one embodiment of the present application, the first hinge 31 is integrally connected to the frame 2 and extends from the frame 2 toward or away from the wearer, so that the first hinge 31 protrudes from the frame 2, and the second hinge 32 is rotatably connected to the portion of the first hinge 31 protruding from the frame 2, so as to prevent the frame 2 from hindering the second hinge 32 from rotating in the second direction after charging is completed, thereby preventing the frame 2 from hindering the support frame 20 from driving the solar charging element 10 to flip along the second direction to cover the frame 2.

[0054] like Figure 1 As shown, in some embodiments, the number of the articulated mechanisms 30 is at least two, and at least two articulated mechanisms 30 are spaced apart along the length direction of the frame 2. At least two articulated mechanisms 30 respectively connect the frame 2 and the supporting frame 20, thereby improving the connection stability between the supporting frame and the frame 2, and the flipping stability of the supporting frame 20.

[0055] Combine Figure 1 and Figure 3 In some embodiments, there are two hinge mechanisms 30 , the first bearing portion 201 is connected to the frame 2 through one hinge mechanism 30 , and the second bearing portion 202 is connected to the frame 2 through the other hinge mechanism 30 , thereby realizing the connection between the bearing frame 20 and the frame 2 .

[0056] Combine Figure 1In some embodiments, the solar charging element 10 is rotatably connected to the side of the frame 2 away from the wearer via the support frame 20. The angle at which the solar charging element 10 rotates relative to the frame 2 following the support frame 20 is within a range of 0° to 90°. In this embodiment, by placing the solar charging element 10 on the side of the frame 2 away from the wearer, the solar charging element 10 can rotate a certain angle following the support frame 20 under the action of an external force, effectively ensuring that the solar charging element 10 can fully receive solar energy.

[0057] Combine Figure 1 In other embodiments, the solar charging element 10 is rotatably connected to the side of the frame 2 facing the wearer through the supporting frame 20. The angle range of the solar charging element 10 following the supporting frame 20 to flip relative to the frame 2 is 0° to 270°, so that the solar charging element 10 can follow the supporting frame 20 to flip relative to the frame 2 to the side of the frame 2 away from the wearer, so that when the wearable device 100 is worn, the solar charging element 10 can receive solar energy.

[0058] like Figure 1 and Figure 3 As shown, an embodiment of the present application also provides a wearable device 100, including a frame 2, a controller, an energy storage element and the above-mentioned charging component 1, the frame 2 includes a frame 21 and temples (not shown), the controller and the energy storage element are both arranged in the temples of the frame 2, the solar charging element 10 and the energy storage element are both electrically connected to the controller, and the solar charging element 10 is rotatably connected to the frame 21 of the frame 2 through the supporting frame 20.

[0059] The wearable device 100 of this embodiment uses the above-mentioned charging assembly 1, and utilizes the solar charging element 10 to receive solar energy and convert the solar energy into electrical energy, which is then processed by the controller and stored in the energy storage element. In this way, the wearable device 100 can be continuously powered without the use of an external power supply, thereby eliminating the need to carry charging cables or charging boxes and other devices, making charging convenient. Among them, the controller is used to process the electrical signals transmitted from the solar charging element 10 and manage the charging and discharging of the energy storage element. The energy storage element is used to store and release electrical energy. The solar charging element 10 can receive solar energy and continuously charge the wearable device 100. As a result, the wearable device 100 can continue to be worn and used during the charging process, which helps to extend the use time of the wearable device 100 and improve the user experience.
