[0040] like Figure 1 and Figure 2 As shown, the wearable device controller 100 disclosed in this embodiment is used to remotely control wearable devices such as AR glasses and VR glasses (not shown). The controller 100 is communicatively connected to the wearable device and includes a photoelectric conversion element 10 and a main control circuit board 20. Both the photoelectric conversion element 10 and the main control circuit board 20 are housed within the controller 100. The photoelectric conversion element 10 is electrically connected to the main control circuit board 20. The photoelectric conversion element 10 is used to absorb ambient light to perform photoelectric conversion and generate electrical energy. Ambient light includes at least one of natural light and artificial light. Natural light can be sunlight, and artificial light can be light generated by LED lamps, halogen lamps, etc. The ambient light provides sufficient illumination for the photoelectric conversion element 10 to generate electrical energy to at least supply the main control circuit board 20.
[0041] In this embodiment, the controller 100 can absorb outdoor sunlight during the day and artificial light at night or indoors through the photoelectric conversion element 10, so as to achieve all-weather absorption of indoor and outdoor ambient light. It also converts the absorbed light energy into electrical energy through the photoelectric conversion element 10 to supply at least the main control circuit board 20 of the controller 100. Thus, the photoelectric conversion element 10 can generate electricity on its own in the presence of light and supply power to the controller 100. The whole process does not require the use of a charger to frequently charge the controller 100, thereby reducing or even avoiding the impact of frequent charging on the long-term use of the controller 100. At the same time, the controller 100 does not need to be designed with a charging interface, and the controller 100 does not need to be carried with a charger when used outdoors, so as to improve the portability of the controller 100.
[0042] like Figure 1 and Figure 2As shown, in some embodiments, the controller 100 includes a housing 30 and an energy storage element 40. The housing 30 can be made of a transparent or semi-transparent material to allow light to pass through. The photoelectric conversion element 10, the main control circuit board 20, and the energy storage element 40 are all housed within the housing 30. The energy storage element 40 is electrically connected to the main control circuit board 20 and is used to store and release electrical energy. In this embodiment, the electrical energy generated by the photoelectric conversion element 10 can supply the main control circuit board 20 of the controller 100 and can also be stored in the energy storage element 40. This allows the controller 100 to be powered by the energy storage element 40 even when the ambient light intensity is low or in a dark environment, supporting all-weather use of the controller 100 and extending its operating time.
[0043] like Figure 1 and Figure 2 As shown, in some embodiments, the housing 30 includes a first flexible outer shell 31 and a second flexible outer shell 32. The first flexible outer shell 31 and the second flexible outer shell 32 are arranged along the thickness direction of the housing 30. The first flexible outer shell 31 is connected to the second flexible outer shell 32 and together with the second flexible outer shell 32, they enclose an accommodating space (not shown). The photoelectric conversion element 10, the main control circuit board 20, and the energy storage element 40 are all housed within the accommodating space. In this embodiment, the housing 30 can use flexible materials such as plastic or silicone to give the housing 30 a certain strength to provide protection. At the same time, the flexible material has good flexibility, allowing the housing 30 to be bent.
[0044] Combination Figure 1 In some embodiments, the controller 100 further includes at least one magnetic element (not shown), which is disposed on the housing 30. For example, multiple magnetic elements are evenly distributed on the housing 30. The magnetic elements can be attracted to the surface of a magnetic object, so that the housing 30 of the controller 100 can be attracted to the surface of an object such as a mobile phone, a laptop, a metal water cup, or a table with a metal area. The user can then indirectly hold the controller 100 by holding the attracted object, thus freeing up the other hand to operate the controller 100 when the user needs to simultaneously hold an object such as a water cup or mobile phone and the controller 100. For example, the magnetic element is a magnet.
[0045] Furthermore, when the distance between the controller 100 and the wearable device is less than a preset distance, the magnetic force of the magnetic connector can be detected by the wearable device, allowing the controller 100 to be sensed by the wearable device. The preset distance can be set as needed. In a specific application scenario, the wearable device is AR glasses. When the distance between the controller 100 and the wearable device is less than the preset distance, and the magnetic force of the magnetic connector is detected by the AR glasses, the controller 100 and the AR glasses automatically pair, or the operation menu displayed in the virtual image projected by the AR glasses is automatically opened.
[0046] Combination Figure 1 In some embodiments, along the thickness direction of the housing 30, the housing 30 has a first surface (not shown) and a second surface (not shown), both of which are opposite to the accommodating space. The first surface can be understood as the upper surface of the housing 30 when it is placed horizontally, and the second surface can be understood as the lower surface of the housing 30 when it is placed horizontally. Furthermore, the housing 30 also has a third surface (not shown), which is opposite to the accommodating space and connects to both the first and second surfaces. The third surface can be understood as the peripheral surface of the housing 30. In one implementation, multiple magnetic attractors are evenly arranged around the first surface, and / or multiple magnetic attractors are evenly arranged around the second surface; in another implementation, multiple magnetic attractors are evenly arranged on the third surface. Specifically, a groove can be formed on the outer surface of the housing 30, and the magnetic attractors can be embedded and fixed within the groove.
[0047] like Figure 1 and Figure 2 As shown, in some embodiments, the photoelectric conversion element 10 and the energy storage element 40 are stacked along the thickness direction of the housing 30, making reasonable use of the space within the housing 30. Furthermore, the energy storage element 40 and the main control circuit board 20 are spaced apart along a first direction, which is perpendicular to the thickness direction of the housing 30.
[0048] like Figure 1 and Figure 2 As shown, in some embodiments, there are two photoelectric conversion elements 10. Along the thickness direction of the housing 30, the energy storage element 40 is located between the two photoelectric conversion elements 10. Specifically, along the thickness direction of the housing 30, one of the two photoelectric conversion elements 10 is located between the first surface and the energy storage element 40, and the other photoelectric conversion element 10 is located between the second surface and the energy storage element 40. In this embodiment, the two photoelectric conversion elements 10 can respectively receive ambient light transmitted through the first and second surfaces, allowing the two photoelectric conversion elements 10 to receive ambient light from different directions. Compared to only placing the photoelectric conversion element 10 on one side of the energy storage element 40, this improves power generation efficiency.
[0049] Combination Figure 2 In some embodiments, the photoelectric conversion element 10 is one of a flexible solar cell, a copper indium gallium selenide (CIGS) flexible thin film, or a flexible solar device made of a light-collecting solar material, thereby converting light energy into electrical energy. The light-collecting solar material can be a metal, monocrystalline silicon, perovskite, or other similar materials.
[0050] Combination Figure 2In this embodiment, the photoelectric conversion element 10 is made of flexible solar energy material, which gives it good bending and flexibility, allowing it to be bent into different shapes to adapt to different housing shapes, such as card-shaped, ring-shaped, and cufflink-shaped housings 30. Cufflink-shaped refers to the shape of cufflinks such as spherical cufflinks and snap-button cufflinks. Furthermore, the copper indium gallium selenide (CIGS) flexible film can maintain high photoelectric conversion efficiency in low-light environments (such as indoors), thus enabling power generation in low-light environments by using the CIGS flexible film as the controller 100 for the photoelectric conversion element 10.
[0051] like Figure 1 and Figure 2 As shown, the photoelectric conversion element 10 is in the form of a thin film, which can be adapted to the shape of the card-shaped housing 30.
[0052] like Figure 1 and Figure 2 As shown, in some embodiments, the energy storage element 40 is a miniature thin-film lithium battery. Miniature thin-film lithium batteries have high energy density, can store sufficient electrical energy, and can also reduce the thickness of the energy storage element 40. Furthermore, the energy storage element 40 is sheet-shaped and can be adapted to the card-shaped housing 30.
[0053] like Figure 1 and Figure 2 As shown, in some embodiments, the controller 100 further includes a flexible circuit board 50 and a touch module (not shown). The flexible circuit board 50 and the main control circuit board 20 are arranged along the thickness direction of the housing 30. For example, the flexible circuit board 50 is stacked on the main control circuit board 20, covering part or all of the main control circuit board 20. The touch module is electrically connected to the main control circuit board 20 through the flexible circuit board 50. The flexible circuit board 50 has a first side (not shown) and a second side (not shown), which are arranged along the thickness direction of the housing 30. The first side faces away from the main control circuit board 20, and the second side faces the main control circuit board 20. The touch module is formed on the first side and is used to generate a first trigger command when the area of the housing 30 facing the touch module is touched. The main control circuit board 20 can send the first trigger command to the wearable device to realize scene interaction between the controller 100 and the wearable device. Further, the touch module is a multi-touch module.
[0054] In this embodiment, the area of the housing 30 facing the touch module is the touch area (not shown). The user can trigger the touch module to generate a first trigger command by touching the touch area. For example, sliding, clicking, or double-clicking the touch area can generate different first trigger commands, enabling the wearable device to perform different tasks. In some application scenarios, the wearable device is AR glasses. The user's finger sliding on the touch area can adjust the brightness of the virtual image projected by the wearable device. For example, sliding the finger in one direction (e.g., sliding downwards) can decrease the brightness of the virtual image, while sliding in another direction (e.g., sliding upwards) can increase the brightness of the virtual image.
[0055] like Figure 1 and Figure 2 As shown, in some embodiments, the main control circuit board 20 is provided with a first communication module (not shown), and the wearable device is provided with a second communication module (not shown). The first communication module is electrically connected to the main control circuit board 20 and is used to communicate with the second communication module to realize the communication connection between the controller 100 and the wearable device, thereby establishing a data connection between the wearable device and the controller 100. Furthermore, the controller 100 also includes a first inertial measurement module (not shown) disposed on the main control circuit board 20. The first inertial measurement module is electrically connected to the main control circuit board 20. The first inertial measurement module can be an IMU (Inertial Measurement Unit) sensor including a three-axis electronic gyroscope sensor and a three-axis accelerometer. The first inertial measurement module can measure the acceleration and angular velocity of the controller 100 in three-dimensional space and calculate the motion state of the controller 100 accordingly. The motion state of the controller 100 includes the speed and attitude of the controller 100.
[0056] In this embodiment, since the controller 100 moves under the action of the user's hand, the acceleration and angular velocity of the controller 100 can be measured by the first inertial measurement module, which can monitor the user's hand movements. The first inertial measurement module then generates control commands based on the user's hand movements. For example, when the user's hand causes the controller 100 to rotate, tilt, or bend, the first inertial measurement module generates control commands accordingly. These control commands can be customized based on actual needs. Furthermore, the main control circuit board 20 can also receive control commands and send them to the second communication module of the wearable device via the first communication module, thereby enabling scene interaction between the controller 100 and the wearable device. In some application scenarios, the wearable device is AR glasses, with the length of the controller 100 representing the left-right direction and the width representing the front-back direction. In this case, when the user rotates the controller 100 forward, the volume of the AR glasses can be increased; when the user rotates the controller 100 backward, the volume of the AR glasses can be decreased. When the user flips the controller 100 left or right, the virtual image projected by the AR glasses can be turned. In other application scenarios, rotating the controller 100 can change the display perspective of the virtual image projected by the AR glasses.
[0057] like Figure 2 As shown, in some embodiments, the first inertial measurement module and the first communication module are staggered, which can reduce the space occupied by the first inertial measurement module and the first communication module on the main control circuit board 20.
[0058] like Figure 2 As shown, in some embodiments, the first communication module includes at least one of an ultra-wideband (UWB) communication module and a Bluetooth module. The ultra-wideband communication module is used to locate the controller 100, and the ultra-wideband communication module is also used to wirelessly connect to the second communication module. The Bluetooth module is used to wirelessly connect to the second communication module to realize data exchange between the controller 100 and the wearable device.
[0059] In this embodiment, the communication module can be an ultra-wideband (UWB) communication module, which can be used to locate the controller 100, thereby sensing the specific location of the controller 100. In some application scenarios, the controller 100 establishes communication with a mobile phone, and the user determines the location of the controller 100 through the mobile phone, reducing the possibility of the controller 100 being lost. In other application scenarios, the wearable device is AR glasses. The controller 100 is set to pair with the AR glasses when the distance between the controller 100 and the AR glasses is less than a preset distance, thereby waking up the controller 100. The awakened controller 100 can control the AR glasses within a set area centered on the AR glasses, and will automatically go into sleep mode when the controller 100 leaves the set area.
[0060] Furthermore, the first inertial measurement module, combined with an ultra-wideband communication module (wireless carrier communication technology), can achieve virtual pointer control. Specifically, using related technologies, the wearable device is AR glasses, which can project virtual images displaying virtual pointers. The AR glasses also have a second inertial measurement module (not shown). This second inertial measurement module can be an IMU (Inertial Measurement Unit) sensor including a three-axis electronic gyroscope sensor and a three-axis accelerometer. The second inertial measurement module can monitor the user's head movement by measuring the acceleration and angular velocity of the AR glasses, and transmit the identified head movement as a signal to the controller 100 via the ultra-wideband communication module. This allows the controller 100 to also monitor the user's head movement, and thus generate control commands based on the user's head movement to control the movement of the virtual pointer in the virtual image. For example, the controller 100 can control the movement of the virtual pointer by monitoring the user's head rotation or tilt.
[0061] like Figure 1 and Figure 2 As shown, in one specific embodiment, the flexible circuit board 50 and the main control circuit board 20 are stacked. A touch module with multi-touch functionality is formed on the first side of the flexible circuit board 50. The side of the main control circuit board 20 opposite to the flexible circuit board 50 integrates an ultra-wideband communication module and a first inertial measurement module. The ultra-wideband communication module detects the position of the controller 100 to detect the user's hand position, and then the first inertial measurement module detects and analyzes the motion trajectory of the controller 100, thereby converting the user's hand movement into control commands. For example, the user can move the virtual pointer by waving their hand holding the controller 100, and the user can also click the virtual pointer by clicking the area of the housing 30 facing the touch module.
[0062] Furthermore, in some application scenarios, the wearable device is AR glasses. The controller 100 establishes communication with the AR glasses, and the AR glasses establish communication with smart home devices such as refrigerators to control the refrigerator to open or close. Specifically, the virtual screen projected by the AR glasses displays an open refrigerator icon and a close refrigerator icon. The controller 100 detects the user's hand movements to generate control commands based on the user's hand movements, thereby controlling the virtual pointer in the virtual screen to move between the open refrigerator icon and the close refrigerator icon. Depending on the actual needs, when the virtual pointer moves to the open refrigerator icon and the close refrigerator icon respectively, the user clicks the area of the housing 30 facing the touch module to click the virtual pointer, thereby clicking the open refrigerator icon and the close refrigerator icon to open or close the refrigerator.
[0063] In other application scenarios, the wearable device is AR glasses. The controller 100 establishes communication with the AR glasses. The AR glasses have a camera. When the camera scans the payment QR code, the payment screen is displayed in the virtual image projected by the AR glasses. The user can click on the area of the housing 30 facing the touch module as instructed to complete the information input and complete the mobile payment.
[0064] Combination Figure 2 In some implementations, the main control circuit board 20 is equipped with a health monitoring module (not shown) for detecting the health status of the subject. For example, the health monitoring module includes an infrared sensor (not shown) for detecting the subject's heart rate and body temperature. In some applications, the controller 100 performs functions such as adjusting display brightness or initiating health feedback based on the health status detected by the health monitoring module.
[0065] Combination Figure 2In some embodiments, the main control circuit board 20 is equipped with a light intensity sensing module (not shown) and a battery management module (not shown). The light intensity sensing module and the battery management module are staggered on the main control circuit board 20 to reduce the space occupied by the light intensity sensing module and the battery management module on the main control circuit board 20. The light intensity sensing module is used to detect the actual light intensity of the ambient light. The energy storage element 40 is used to stop supplying power when the actual light intensity is greater than or equal to the set light intensity. The set light intensity can be the ambient light intensity that can be set as needed, such as 200 lux. This embodiment does not have a specific limitation. The energy storage element 40 is also used to start supplying power when the actual light intensity is less than the set light intensity. In this way, when the ambient light intensity is high, the photoelectric conversion element 10 generates electricity efficiently and provides electrical energy to the main control circuit board 20, flexible circuit board 50 and other electrical components, reducing the use of the energy storage element 40 and extending its service life. When the ambient light intensity is weak, the photoelectric conversion element 10 and the energy storage element 40 supply power to the electrical components together to reduce the power consumption of the energy storage element 40. For example, the light intensity sensing module includes a light intensity sensor (not shown) for detecting the actual light intensity of ambient light.
[0066] Furthermore, the battery management module is used to detect the remaining power of the energy storage element 40. The battery management module is also used to ensure that the touch module, light intensity sensor module, and main control circuit board 20 operate normally when the remaining power is less than or equal to a set power level. In this case, the controller 100 can shut down the first inertial measurement module, the first communication module (such as an ultra-wideband communication module), and the health monitoring module to reduce power consumption and extend the operating time of the controller 100 in low-power mode, thereby improving the controller 100's battery life. For example, the battery management module includes a power sensor used to detect the remaining power of the energy storage element 40. The set power level can be 20% of the battery capacity, and can be designed as needed; this embodiment does not impose specific limitations.
[0067] Combination Figure 1 and Figure 2 In one specific embodiment, the light intensity sensing module, health monitoring module, battery management module, first inertial measurement module, and first communication module are disposed on the same side as the flexible circuit board 50. Alternatively, along the thickness direction of the housing 30, the light intensity sensing module, health monitoring module, battery management module, first inertial measurement module, and first communication module are all located on one side of the main control circuit board 20, and the flexible circuit board 50 is located on the other side of the main control circuit board 20.
[0068] like Figure 1 and Figure 2As shown, in some embodiments, the controller 100 further includes a button 60, which is disposed on the main control circuit board 20 and partially protrudes from the housing 30. Specifically, the housing 30 is provided with a through hole 33 for the button 60 to pass through. The button 60 is electrically connected to the main control circuit board 20. The button 60 includes at least one of a power button, a mode switching button, and a volume button.
[0069] In this embodiment, a physical button 60 can be added on top of the touch module. The button 60 is pressed by the user and generates a second trigger command. The main control circuit board 20 can also send the second trigger command to the wearable device, enabling scene interaction between the controller 100 and the wearable device. The button 60 includes at least one of a power button, a mode switch button, and a volume button. Pressing the button 60 can turn the controller 100 on / off, switch the controller 100's mode, and adjust the volume of the wearable device to adapt to different operating scenarios. In some application scenarios, the controller 100 is configured with a low-power mode and a working mode. The button 60 includes a mode switch button. When the mode switch button is pressed, the controller 100 can switch from the working mode to the low-power mode, reducing the use of functional modules such as the first inertial measurement module and the first communication module, thus reducing the power consumption of the controller 100.
[0070] like Figure 1 and Figure 2 As shown, in some embodiments, the thickness of the controller 100 is set to within 4mm, achieving an ultra-thin design of the controller 100, which makes it convenient to carry and store the controller 100. Furthermore, the thickness of the photoelectric conversion element 10 is 0.15mm to 0.25mm, for example, 0.2mm; the thickness of the energy storage element 40 is 0.49mm to 0.51mm, for example, 0.5mm; the thickness of the first flexible shell 31 and the second flexible shell 32 are both 0.6mm to 1.1mm, for example, 0.6mm; the thickness of the magnetic suction element is 0.15mm to 0.25mm, for example, 0.2mm; the total thickness of the main control circuit board 20, flexible circuit board 50, touch module, first communication module, first inertial measurement module, light intensity sensing module, health monitoring module and battery management module is 1.2mm to 1.5mm, for example, the thickness of the main control circuit board 20 is 0.8mm, and the total thickness of the flexible circuit board 50, touch module, first communication module, first inertial measurement module, light intensity sensing module, health monitoring module and battery management module is 0.4mm. The above design can reduce the overall thickness of the controller 100, making the controller 100 thinner and easier to carry and store.
[0071] Furthermore, based on the design that the thickness of the first flexible shell 31 and the second flexible shell 32 is 0.6mm, the thickness of the first flexible shell 31 and the second flexible shell 32 can be increased by 0.1mm-0.5mm to improve the protective force of the shell 30, thereby reducing the occurrence of damage to the controller 100.

Any equivalent structural transformations made based on the content of this application's specification and drawings under the concept of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
