Description

Technical Field

[0001] This invention relates to the field of laptop computer technology, and more particularly to a laptop computer with solar charging capability. Background Technology

[0002] Currently, some electronic devices on the market have begun to use solar cells to provide auxiliary power for portable devices. For example, some outdoor power banks, smartwatches, and a small number of tablet devices have integrated small solar panels to use solar energy for slow charging.

[0003] In the field of laptop computers, relevant technical solutions have already been disclosed. For example, patent CN201060441Y discloses a "solar-powered laptop computer" in which a solar panel is set on the outer surface of the liquid crystal display. The power generated by the solar panel is converted into the computer's operating voltage by the DC-DC converter circuit of the electronic adapter and then transmitted to the built-in battery.

[0004] Patent CN208622060U discloses a "notebook computer" including a solar panel, a solar controller, a battery, and an angle adjustment mechanism. The solar panel is tilted at an adjustable angle on the casing of the display.

[0005] However, these existing technical solutions still have the following technical problems: the output power of existing products under typical lighting conditions is still relatively low, the charging speed is slow under actual outdoor non-ideal lighting conditions, making it difficult to meet the energy consumption requirements of laptops during normal operation, and the level of intelligent energy management is insufficient. The energy management modules in existing technical solutions are relatively simple, mostly only realizing a direct or simple voltage regulation connection between the solar panel and the battery, lacking the ability to dynamically adjust the charging strategy according to conditions such as light intensity, temperature, and battery charge, resulting in low energy utilization efficiency, and the structural integration and durability need to be improved. The addition of solar components may increase the thickness and weight of the body, affecting the overall portability and durability of the product. Furthermore, the angle of the integrated solar panel cannot be adjusted, resulting in extremely poor sunlight reception during use, affecting power supply. Based on this, a laptop with solar charging function is proposed. Summary of the Invention

The solar panel is integrated on the upper surface shell of the laptop body, and the area of ​​the solar panel accounts for more than 80% of the area of ​​the upper surface shell of the laptop body.

The adjustment groove is connected to an adjustment rod via an adjustment boss. The other end of the adjustment rod is connected to a roller via a rotating shaft. An adjustment fastening stud is provided on the adjustment rod. The adjustment fastening stud passes through the adjustment boss and contacts the inner wall of the adjustment groove.

[0011] As a preferred embodiment, the segmented light energy acquisition circuit divides the solar panel into 4 to 16 independent acquisition units, each of which is equipped with an independent voltage detection circuit and a current detection circuit.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] Example, refer to Figures 1 to 9 A laptop computer with solar charging capability includes a laptop body and a solar panel 4 mounted on the laptop body. The laptop body includes a motherboard 1, a display screen 2, a built-in battery 3, a light adjustment unit, and a photovoltaic management system. The light adjustment unit includes an additional frame 5 disposed on the upper surface of the laptop body. One end of the additional frame 5 is connected to both sides of the solar panel 4 via an offset sliding member. The side of the solar panel 4 away from the offset sliding member is provided with a folding support roller. The offset sliding member includes a sliding plate 6 rotatably connected to the solar panel 4 via a connecting shaft. The additional frame 5 is provided with a sliding guide groove 7. A sliding block located in the sliding guide groove 7 is fixedly connected to the side wall of the sliding plate 6.

[0024] The folding support roller component includes an adjustment groove 8 formed on the side wall of the solar panel 4. The adjustment groove 8 is connected to an adjustment rod 10 via an adjustment boss 9. The other end of the adjustment rod 10 is connected to a roller 11 via a rotating shaft. An adjustment fastening stud 12 is provided on the adjustment rod 10. The adjustment fastening stud 12 passes through the adjustment boss 9 and contacts the inner wall of the adjustment groove 8.

[0025] The light adjustment unit allows users to manually or automatically adjust the tilt angle and extension length of the solar panel 4 according to the angle of sunlight incidence. Specifically, the sliding plate 6 can slide back and forth along the sliding guide groove 7, thereby changing the horizontal position of the solar panel 4 relative to the upper surface of the laptop body; at the same time, the solar panel 4 can rotate relative to the sliding plate 6 via the connecting shaft to achieve tilt angle adjustment. When the solar panel 4 slides outward and tilts, the folding support roller assembly unfolds from the adjustment groove 8 via the adjustment rod 10, and the roller 11 contacts the desktop or other supporting surface to provide auxiliary support for the extended solar panel 4, preventing the laptop from tipping over due to the forward shift of the center of gravity. The adjusting fastening stud 12 is used to lock the extension length of the adjustment rod 10 to ensure support stability. When not in use, the adjustment rod 10 can be folded back into the adjustment groove 8, and the roller 11 is hidden in the side wall of the solar panel 4, keeping the overall appearance of the machine neat.

[0026] This light adjustment unit enables the solar panel 4 to flexibly adjust its orientation and tilt angle according to the real-time position of the sun, maximizing the amount of light energy received per unit time. Actual measurements show that it can improve power generation efficiency by more than 30%. At the same time, the design of the folding support rollers ensures the stability of the laptop after the solar panel 4 is unfolded, avoiding the risk of tipping over due to tilting force. Furthermore, the folding does not increase the overall thickness of the laptop, thus balancing portability and power generation efficiency.

[0027] The solar panel 4 is integrated on the upper surface shell of the laptop body, and the area of ​​the solar panel 4 accounts for more than 80% of the area of ​​the upper surface shell of the laptop body.

[0028] It should be noted that the upper surface of the laptop body, commonly referred to as the A-side (the back of the display screen 2), has a solar panel 4 attached to the inner surface of the A-side shell via an optically transparent adhesive layer or directly integrated into the A-side shell. Its coverage area exceeds 80% of the total A-side area, far exceeding the 50%–70% coverage ratio of existing products. To achieve such a high area ratio, the solar panel 4 adopts a frameless or narrow bezel design, avoiding the hinge area and antenna window. Simultaneously, components such as the camera and microphone are integrated into the reserved openings of the solar panel 4 or the lower edge of the display screen 2. The solar panel 4 preferably uses flexible thin-film solar cells (such as copper indium gallium selenide or perovskite) to conform to the curved contours of the A-side while reducing overall weight.

[0029] The advantages of adopting the above structure are: the area of ​​solar panel 4 is increased to more than 80% of the area of ​​side A, which significantly increases the light energy receiving area. Under standard lighting conditions, the solar output power can reach 15 watts to 25 watts, which is more than double that of the existing technology, making solar charging truly practical for continuously replenishing the power of laptops; at the same time, the borderless or narrow bezel design maintains the aesthetics and screen ratio of the laptop without affecting the user experience.

[0030] The photovoltaic management system includes a segmented solar energy harvesting circuit, which divides the solar panel 4 into multiple independent harvesting units for separate energy harvesting; the photovoltaic management system also includes a maximum power point tracking module, which is connected to the output of the segmented solar energy harvesting circuit, and is used to adjust the circuit parameters in real time so that the solar panel 4 operates at its maximum power point; the battery management system also includes an intelligent energy management module, which is connected to the maximum power point tracking module and the battery management system, and is used to acquire ambient light intensity and battery status information, and dynamically adjust the charging strategy; the photovoltaic management system is connected to the battery management system through an energy dispatch interface, and is used to dispatch solar power to the built-in battery 3.

[0031] The photovoltaic management system is the core control unit for achieving efficient solar charging in this invention. The segmented light energy acquisition circuit divides the large-area solar panel 4 into multiple independent units (e.g., divided in a matrix). Each unit outputs power independently to avoid a sudden drop in the overall panel output due to local shading (such as leaves, cloud shadows, or user's hand blocking the light). The maximum power point tracking module tracks the voltage-current characteristic curve in real time at each acquisition unit or the overall panel output, and ensures that the solar panel 4 always outputs the maximum power under the current light conditions through pulse width modulation or switching adjustment.

[0032] As the higher-level decision-making unit, the intelligent energy management module comprehensively analyzes information such as ambient light (from the light sensor), temperature (from the temperature sensor), and the voltage, current, charge, and health status of the built-in battery 3, and outputs the optimal charging parameters (such as charging voltage, current limit, charging mode, etc.). The energy scheduling interface, according to the instructions of the intelligent energy management module, controls the DC-DC converter and switching transistor to deliver solar power to the built-in battery 3 or directly supply the laptop load with appropriate voltage and current.

[0033] By combining segmented data acquisition with maximum power point tracking, this invention can maintain more than 60% of its nominal power generation capacity even under partial shading or low light conditions, overcoming the defect of traditional solar-powered laptops that "stop completely at one level." The intelligent energy management module and the battery management system are deeply integrated to achieve dynamic optimization of the charging strategy, avoiding overcharging and overheating, and extending the battery cycle life by more than 20%. The overall photovoltaic management system has an energy conversion efficiency of more than 95%, which is far higher than the existing simple diode isolation scheme.

[0034] Furthermore, the segmented solar energy harvesting circuit divides the solar panel 4 into 4 to 16 independent harvesting units. Each independent harvesting unit is equipped with an independent voltage detection circuit and current detection circuit. The maximum power point tracking module uses the incremental conductance method, the perturbation observation method, or the constant voltage method to achieve maximum power point tracking.

[0035] The number of segments can be flexibly selected based on the physical size of the solar panel 4 and the expected usage scenario: 4 units are suitable for low-cost solutions, 8 units for balanced solutions, and 16 units for high-precision low-light optimization solutions. Each independent acquisition unit is equipped with a high-precision analog-to-digital conversion circuit to monitor the voltage and current values ​​of the unit in real time and transmit the data to the maximum power point tracking module. The maximum power point tracking module can perform maximum power point tracking independently for each unit, or connect the units in series or parallel for unified tracking. The incremental conductance method quickly locks the maximum power point by comparing the current change in conductance with the negative value of conductance, which is suitable for scenarios with rapid changes in light intensity; the perturbation observation method is simple to implement and low in cost; the constant voltage method uses empirical values ​​(approximately 76% to 80% of the open-circuit voltage) to approximate the maximum power point, resulting in the lowest power consumption. The module also has a soft-start circuit and a reverse discharge protection circuit to prevent the built-in battery 3 from discharging backwards to the solar panel 4.

[0036] By employing 4 to 16 independent acquisition units, an optimal balance between cost and performance is achieved. Independent voltage and current detection for each unit enables the maximum power point tracking module to accurately identify the optimal operating point of each unit, resulting in a 15% to 25% improvement in overall power generation efficiency compared to traditional single-board structures. Multiple maximum power point tracking algorithms can be automatically switched according to lighting conditions, employing a high-precision incremental conductance method under strong light and switching to a low-power constant voltage method under weak light, thereby reducing the overall system power consumption by approximately 30%.

[0037] The intelligent energy management module includes a light sensor and a temperature sensor. The intelligent energy management module dynamically adjusts the charging current, switches the working mode of the segmented light energy acquisition circuit, or starts and stops the maximum power point tracking function based on at least one of the parameters of light intensity, temperature, battery power, and battery temperature.

[0038] The light sensor typically uses a photodiode or digital light intensity sensor, installed on the edge of the A-side or the keyboard surface, to detect ambient light intensity (unit: lux). Its output value ranges from 0 lux (complete darkness) to 120,000 lux (strong sunlight). At least two temperature sensors are provided: one to detect ambient temperature and the other attached to the surface of the built-in battery 3 or the back of the solar panel 4 to detect operating temperature. The intelligent energy management module stores a preset decision table or fuzzy control rule base.

[0039] For example: when the light intensity is >50,000 lux and the battery charge is <30%, all acquisition units are activated and maximum power point tracking is enabled, charging at the maximum charging current (e.g., 3 amps); when the light intensity is between 2,000 and 10,000 lux and the battery charge is >80%, the constant voltage charging mode is switched and the charging current is reduced to 0.5 amps; when the battery temperature is >50℃, the maximum power point tracking function is immediately suspended and the charging current is reduced to zero. At the same time, a high temperature warning is issued to the user through the operating system. The working modes of the segmented light energy acquisition circuit include: full unit working mode, odd / even unit alternating working mode, and central unit only working mode, etc., to adapt to different light distributions.

[0040] Multi-dimensional parameter fusion decision-making makes the charging strategy more refined and intelligent, ensuring charging speed while maximizing battery health protection; dynamically adjusting the number of acquisition units based on light intensity can reduce the circuit's own power consumption by up to 40% in low light, avoiding inefficient charging that is "not enough to cover costs"; the temperature protection mechanism effectively prevents the risk of battery bulging or thermal runaway caused by charging in high-temperature environments, significantly improving equipment safety.

[0041] The battery management system is configured to allow the solar panel 4 to charge the built-in battery 3 when the battery level is below a preset threshold and the temperature is within the safe operating range; and to cut off the charging path when the battery level is fully charged or the temperature exceeds the safe operating range. The solar panel 4 has a high-transmittance reinforced glass 13 on its surface and elastic buffer strips 14 densely distributed on its bottom. The preset threshold can be set to configurable values ​​such as 20%, 30%, or 50%, which can be set by the user through the laptop's power management software. The safe operating range is typically 0℃ to 45℃ (during charging) or -10℃ to 60℃ (during discharging).

[0042] The advantage of adopting the above structure is that the battery management system physically cuts off the charging path through a built-in charging switch (such as a metal-oxide-semiconductor field-effect transistor), ensuring safety. High-transmittance tempered glass 13 covers the upper surface of the solar panel 4, with a transmittance of not less than 92%, and is treated with anti-glare, anti-fingerprint, and impact-resistant properties (such as Corning Gorilla Glass or Schott Xenon Glass), with a thickness of only 0.4 mm to 1.0 mm.

[0043] Elastic buffer strips 14 are densely distributed on the bottom of the solar panel 4 (i.e., the side facing the display screen 2). They are made of silicone, polyurethane, or thermoplastic polyurethane elastomer material, with a semi-circular or rectangular cross-section. The spacing between adjacent buffer strips is 2 mm to 5 mm, and the height of the buffer strips is 0.5 mm to 1.5 mm. Buffer adapter grooves that match the buffer strips are provided on the upper surface of the laptop body. When the laptop is subjected to external impact or closure, the elastic buffer strips 14 can absorb the impact energy and prevent the solar panel 4 from directly colliding with the display screen 2.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
