Description

Technical Field

[0001] This utility model relates to the field of intelligent robot technology, specifically to an intelligent light-harvesting assistant. Background Technology

[0002] With the increasing demand for higher quality living standards, indoor lighting, as a core component of the home environment, has gradually revealed many problems that urgently need to be addressed. 1. High energy consumption: Traditional electric lights are used for more than 8 hours a day, with a three-person household spending approximately 500-800 yuan annually on lighting, accounting for 15%-20% of basic household electricity consumption. Long-term use leads to persistently high household energy costs. 2. Significant health risks: LED lights generally emit blue light radiation with a peak wavelength of around 450nm. Prolonged exposure can easily cause visual fatigue, and research shows that 60% of children's myopia is directly related to unreasonable indoor lighting environments. 3. Obvious blind spots: Basements, north-facing rooms, and other areas have natural light penetration rates of less than 10%, resulting in low space utilization and a poor living experience due to lack of natural light. 4. Poor scene adaptability: Traditional lighting cannot automatically adjust lighting parameters according to day-night cycles and seasonal changes, making it difficult to meet the personalized lighting needs of different scenarios such as reading, dining, and resting.

[0003] To address the aforementioned issues, existing technologies have developed solar-powered light guiding solutions, but all of them have significant drawbacks. For example, reflector-type light guiding is heavily limited by weather and light guiding distance. In cloudy or rainy weather, or during long-distance light guiding, its light guiding efficiency drops dramatically, failing to guarantee a stable light supply and making it difficult to meet the needs of daily household lighting. Fiber optic light guiding suffers from severe light loss; a large amount of light is lost during transmission, resulting in insufficient light intensity reaching the target area.

[0004] Therefore, there is an urgent need for a home light guide device that can take into account high efficiency and energy saving, health and safety, flexible adaptation and intelligent control, so as to make up for the shortcomings of existing technologies and meet the needs of modern families for low-carbon and healthy lighting.

[0035] The present invention will be further described in detail below with reference to embodiments:

[0036] Example 1

[0037] like Figure 1-8As shown, this utility model provides an intelligent light-harvesting assistant, including a light energy collection mechanism 10, a light guide path support mechanism 20, an angle adjustment mechanism 30, a circular plate 4, a bottom rotation mechanism 50, and a control module arranged sequentially from top to bottom. The control module is electrically connected to each of the mechanisms. The light energy collection mechanism 10 includes a Fresnel lens 11, a support ring 12, and several U-shaped plates 13 arranged in a ring array on its inner bottom. The outer edge of the Fresnel lens 11 is installed on the inner side of the U-shaped plates 13. The top of the support ring 12 is provided with several photovoltaic panels 14 with a projected fan shape. The system also includes a mechanism to drive all photovoltaic panels 14 to synchronously perform expansion or contraction movements radially along the support ring 12. The drive assembly 15 includes a gear ring 151 connected to the inner side of the support ring 12 and gears 152 respectively mounted on the top of the U-shaped plate 13. The gears 152 are meshed with the gear ring 151. The bottom of the photovoltaic panel 14 is connected to a rack 153 that meshes with the gears 152. The bottom of one of the U-shaped plates 13 is connected to a geared motor 154. The output shaft of the geared motor 154 is connected to the corresponding gear 152 above. The control module includes an energy storage battery and an MPPT controller. One end of the MPPT controller is electrically connected to the photovoltaic panel, and the other end is electrically connected to the energy storage battery. It also includes a control module electrically connected to the energy storage battery.

[0038] Furthermore, the Fresnel lens 11 focuses large-area natural light through a special concentric circle pattern, significantly improving light intensity and solving the problem of insufficient intensity when natural light is directly transmitted. The geared motor 2 154 drives the connected gear 3 152 to rotate. Through the meshing transmission of the gear ring 151, all gears 3 152 rotate synchronously, which in turn drives the rack 153 to cause the photovoltaic panel 14 to extend and retract radially along the support ring 12. This ensures that multiple photovoltaic panels 14 move in unison. When the light is strong, the photovoltaic panel 14 contracts to reduce the light-receiving area, and when the light is weak, it expands to increase the light-receiving area, so that the power generation efficiency is always kept in the optimal range.

[0039] Furthermore, the photovoltaic panel 14 adopts a petal-shaped layout to enhance the ability to capture scattered light. A photoelectric sensor is installed on it, including a photoresistor and a 16-bit ADC. The energy storage battery is a lithium iron phosphate battery with a capacity of 12V / 50Ah, capable of storing excess energy to power the device during nighttime or cloudy / rainy days. The control module uses an STM32F407VGT6 microcontroller and can also connect to a gyroscope, a light sensor, a Bluetooth communication module, and an OLED display. The gyroscope is an MPU6050, the Bluetooth communication module is an HC-05 / 08, and the OLED display is a 0.96-inch screen driven by an SSD1306. It receives device attitude data from the gyroscope (model MPU6050), reduces noise using a Kalman filter algorithm, and outputs attitude parameters such as roll and pitch angles to ensure stable light tracking.

[0040] Furthermore, the control module receives ambient light intensity data from a light sensor (photoresistor + 16-bit ADC chip ADS1115), with a measurement range covering 1-100,000 lux, accurately identifying the sun's position and light intensity changes. Simultaneously, it runs a motor PID dual closed-loop algorithm (position loop + speed loop), calculates the PWM duty cycle based on the deviation between the target angle and the feedback angle, and drives the angle adjustment mechanism 30 and the bottom rotation mechanism 50 to achieve sub-second attitude adjustment. It also enables wireless data interaction within 10 meters via a Bluetooth communication module (HC-05 / 08, BLE protocol), supporting users to remotely send commands such as mode switching and angle adjustment.

[0041] Furthermore, the control module is soldered onto a circuit board, which is then fixed inside the device bracket base via mounting slots. The gyroscope and light sensor (photoresistor + ADS1115) are connected to the microcontroller via an I2C bus to transmit attitude and light intensity data in real time. The OLED display is connected to the microcontroller via an SPI bus to display device operating parameters. The Bluetooth communication module is connected to the microcontroller via a UART interface for wireless data interaction. Additionally, an intelligent power management module can be installed inside the bracket base. This module integrates multiple power conversion units and a power metering unit. The multiple power conversion units include an LM2596 step-down module and an LDO regulator. The module supports 6-24V solar power, 3.7-7.4V lithium battery, and 5-24V external power input. The power metering unit uses the INA219, and the intelligent power management module is electrically connected to the energy storage battery and control module. The LM2596 step-down module and LDO regulator module of the intelligent power management module are integrated on the same circuit board, with inputs connected to the photovoltaic panel 14, lithium battery interface, and external power interface, respectively. The output supplies power to the control module and other electrical components. The INA219 power metering chip connects to the microcontroller via I2C bus to monitor the voltage and current of the energy storage battery in real time. The microcontroller controls charging and discharging based on the data to prevent overcharging and over-discharging.

[0042] Furthermore, this device is also equipped with an intelligent supplementary lighting assistant module that is electrically connected to the control module, including an auxiliary LED lighting device (color temperature adjustable from 3000K to 6500K). When the natural light intensity is below 500 lux, the control module automatically starts the auxiliary lighting to supplement the light intensity. At the same time, the auxiliary lighting device can be connected to smart home systems such as Mi Home and HomeKit to realize voice control and scene linkage.

[0043] The light energy collection mechanism 10, the light guide path support mechanism 20, the angle adjustment mechanism 30, the circular plate 4, and the bottom rotation mechanism 50 are arranged sequentially from top to bottom. Their hierarchical layout allows each mechanism to function independently yet work together. The natural light captured by the light energy collection mechanism can be directly transmitted to the room through the light guide path. The angle adjustment and bottom rotation mechanisms ensure that the device is always aligned with the light source. The control module realizes full-process automation, solving the problem of the disconnect between "capture-transmission-adaptation" in traditional light guide devices.

[0044] The control module is connected to the electrical signals of each mechanism, and can adjust the equipment status in real time according to the light intensity, angle changes and indoor needs, so as to achieve "on-demand light capture and intelligent adaptation". Compared with the traditional device with manual adjustment, the efficiency is improved by more than 40%.

[0045] Example 3

[0046] like Figure 1-8 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the light guide path support mechanism 20 includes a frame 21 and a convex lens 22 connected to its inner side. Support rods 23 are connected to the top four sides of the frame 21, and the top ends of the support rods 23 are connected to the support ring 12. L-shaped supports 24 are connected to both sides of the support ring 12, and a light guide mirror 25 is provided between the L-shaped supports 24. A light guide tube 26 is connected to one side of the top of the circular plate 4. It also includes an adjustment component 27 for driving the angle adjustment mechanism 30 to swing left and right. The adjustment component 27 includes a mounting seat 271 mounted on the circular plate 4 and a connecting seat 272 assembled with the angle adjustment mechanism 30. A drive motor 273 is mounted on the mounting seat 271, and the output shaft of the drive motor 273 is connected to the connecting seat 272.

[0047] Furthermore, frame 21 provides a mounting base for convex lens 22, and at the same time, by connecting with support rod 23, it connects the entire light guide path support mechanism 20 with the light energy collection mechanism 10 above, playing a role in bearing and supporting, ensuring the stability of the entire structure, and further converging and guiding the light focused by light energy collection mechanism 10. The convex lens has the function of converging light, and can refocus the light that has been initially focused by the Fresnel lens 11, making the light more concentrated, reducing the divergence of light during transmission, improving the transmission efficiency of light, and ensuring that the light can reach the light guide mirror 25 or light guide tube 26 below more effectively. The light guide mirror 25 reflects or refracts the light transmitted from the convex lens 22, changes the direction of light propagation, and guides the light into the light guide tube 26. The light guide mirror 25 can be designed with different reflection or refraction angles according to actual needs. The light guided by the light guide mirror 25 is transmitted to the area that needs illumination or other target positions, and the drive motor 273 drives the frame 21 to swing horizontally, which, together with the 360° rotation of the bottom rotation mechanism 50, allows the device to cover the changes in the solar azimuth angle throughout the day.

[0048] Furthermore, the light guide tube is made of high-transmittance PC material, with a reflective coating sprayed on the inner wall. The drive motor 273 is a closed-loop stepper motor (model 86J12103-345-12(K-SCG)). The control module sends electrical pulse signals to the closed-loop stepper motor, which converts the electrical pulses into angular displacement to drive the angle adjustment mechanism 30 to adjust the angle, ensuring that the beam is accurately transmitted to the indoor target area. When the power is off, the motor self-locks through electromagnetic force to fix the position of the angle adjustment mechanism 30, preventing shaking from causing the light guide to deviate. The frame 21 and support rod 23 are lightweight alloy main frames with a hollow biomimetic structure design, which reduces weight while ensuring load-bearing capacity.

[0049] Example 2

[0050] like Figure 1-8As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the angle adjustment mechanism 30 includes a frame 2 31 and a drive structure 32. The right-angle ends of the L-shaped supports 24 are respectively provided with guide tubes 33. The opposite ends of the guide tubes 33 are respectively provided with cup bearings 34 connected to the L-shaped supports 24. One of the L-shaped supports 24 has a base 35 mounted on the frame 2 31 on the side away from the cup bearings 34. A reduction motor 36 is connected to the base 35. The output shaft of the reduction motor 36 passes through the guide tubes 33 and is connected to the light guide mirror 25. The drive structure 32 includes two bearing seats 321 spaced apart on the frame 2 31 and located away from the reduction motor 36. A bearing seat 322 is provided between the bearing seats 321 and interleaved with them. A common optical axis 323 is mounted on both bearing seats 321, and one end of the optical axis 323 passes through one of the bearing seats 321. The conduit 33 extends to the opposite side of the L-shaped support 24. The other end of the optical axis 323 extends to the outermost side of the bearing housing 321. Three gears 324 are spaced apart on the optical axis 323. One gear 324 is located between the bearing housings 321, and the other two gears 324 are installed at both ends of the optical axis 323. One gear 324 is connected to the light guide mirror 25. The optical axis 325 is connected to the bearing housing 322. Gears 326 that match the gears 324 are spaced apart on the optical axis 325. The gears 326 mesh with the corresponding gears 324. A mounting plate 327 is provided on the side of the bearing housing 322 away from the bearing housing 321. A micro motor 328 is connected to the mounting plate 327. A drive gear 329 is connected to the output shaft of the micro motor 328. The drive gear 329 meshes with one of the gears 326.

[0051] Furthermore, the angle adjustment mechanism 30, through frame support and multi-stage gear transmission, achieves precise pitch adjustment of the light guide mirror 25 around the horizontal axis, ensuring that natural light always strikes the surface of the light guide mirror at a vertical angle. This solves the problem of "incident angle shift → increased light loss" caused by changes in the solar altitude angle over time and season. Bearing housing 1 321 and bearing housing 2 322 are staggered, providing two-point support for optical axis 1 323 and optical axis 2 325 respectively. Deep groove ball bearings control the radial runout of the shaft system within 0.01mm, ensuring stable gear meshing backlash and light... The three gears 324 on shaft 323 mesh with the three gears 326 on optical shaft 325 to form a symmetrical transmission structure. The gears at both ends are connected to the light guide mirror and the drive end respectively, and the middle gear plays a synchronizing role to make the force on both sides of the light guide mirror balanced, avoiding the mirror tilt caused by unilateral drive, and ensuring that the reflected light spot offset is ≤0.3mm / m. The micro motor 328 transmits power through the drive gear 329. With the help of the light sensor data of the control module, the angle of the light guide mirror can be corrected in real time to ensure that efficient light guiding can still be maintained in unstable lighting scenarios such as cloudy weather.

[0052] Furthermore, the angle adjustment mechanism 30 is also equipped with a four-stage slope truncated beam photoelectric sensor, a cylindrical structure precision tracking device, and a four-stage slope truncated beam photoelectric sensor with 16 silicon photovoltaic cells arranged symmetrically in four groups along the east, west, south, and north directions on the four-stage slope surface for coarse positioning of the sun's position. It is electrically connected to the control module and outputs a light intensity signal. Specifically, the photovoltaic panel 14 is in a four-stage slope shape with photoelectric sensors on its surface. The cylindrical structure precision tracking device includes a cross-shaped light-transmitting aperture, a Fresnel lens, a rotating shaft with black and white coating, and four silicon photovoltaic cells. The control module controls the micro motor 328 and the geared motor 36 to rotate by comparing the output signals of the four silicon photovoltaic cells, achieving an accuracy of ±0.1°. Angle adjustment: During operation, the photoelectric sensor of the four-sided truncated pyramid first detects the light intensity in the four directions of east, west, south, and north. The control module compares the signal differences and drives the geared motor 36 to drive the light energy collection mechanism 10 to quickly adjust the angle through gears 324 and 326, thus achieving coarse positioning of the sun. Subsequently, the black and white paint on the rotating shaft of the cylindrical fine tracking device causes the surrounding silicon photovoltaic cells to receive light intermittently, outputting square wave signals. The control module calculates the square wave amplitude deviation and drives the drive motor 273 to finely adjust the angle of the light energy collection mechanism 10 until the output amplitude of the four silicon photovoltaic cells is all 0.25U0 (U0 is the full-amplitude voltage), completing the fine positioning and ensuring that the light energy collection mechanism 10 is accurately aligned with the sun.

[0053] Example 4

[0054] like Figure 1-8 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the bottom rotating mechanism 50 includes a bracket 51 and a rotating base 52 with a top opening and a D-shaped projection connected above it. The rotating base 52 contains a worm gear 53 installed at the bottom of the circular plate 4. A first mounting tube 54 is symmetrically arranged within the arc surface of the rotating base 52, and a second mounting tube 55 is symmetrically arranged within the horizontal plane of the rotating base 52. The first mounting tube 54 and the second mounting tube 55 are respectively arranged opposite to each other. Mounting shafts 56 are respectively provided on the inner sides of the first mounting tube 54 and the second mounting tube 55 on the same axis. A worm gear 57 is connected between the mounting shafts 56. The worm gear 57 is located on both sides of the worm gear 53 and meshes with it. The worm gear 57 is fixedly connected to one end of the mounting tube 55 with a rotating gear 58. A fixing plate 59 is installed on the outer side of the horizontal plane of the rotating base 52. A drive motor 5a is installed on the fixing plate 59. A limiting bushing 5b is provided on the outer side of the output shaft of the drive motor 5a and passes through the rotating base 52. The output shaft of the drive motor 5a extends into the rotating base 52 and is connected to a drive gear 5c. Driven gears 5d are meshed on both sides of the drive gear 5c. The driven gears 5d are meshed with the corresponding rotating gears 58. The driven gears 5d are connected to the rotating base 52 through connecting rods and are rotatably connected to the connecting rods.

[0055] Furthermore, the worm gear 53 and worm 57 are noise-reducing, with operating noise controlled below 40dB. Based on the solar azimuth angle change data, the control module drives the drive gear 5c to rotate via the drive motor 5a, which in turn drives the driven gear 5d and the rotating gear 58 to rotate the worm 57, which in turn drives the worm gear 53 to rotate, causing the circular plate 4 and the upper mechanism to rotate horizontally 360°, ensuring that solar energy can be captured at different times of the day. The self-locking characteristics of the worm gear 53 and worm 57 can also fix the rotation angle in the event of power failure or wind interference, preventing the device from shifting.

[0056] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
