Description

Technical Field

[0001] This invention relates to the field of solar power generation, and more particularly to a solar-powered outdoor portable power source. Background Technology

[0002] Solar-powered portable power banks are essential energy equipment for fieldwork, outdoor activities, and emergency power supply. Their performance and reliability directly affect the continuous operation of electrical equipment and the user experience. In off-grid power supply scenarios, the solar charging system and battery energy storage unit need to work together to ensure efficient energy collection and stable output. Due to the complex and variable outdoor environment and the intermittent nature of energy demand, portable power banks must possess good environmental adaptability, efficient energy management capabilities, and convenient operation.

[0003] Traditional solar-powered outdoor portable power banks generally suffer from limitations such as low heat dissipation efficiency and insufficient ease of operation. Their cooling systems typically rely on passive or independently controlled active cooling methods, making it difficult to respond promptly to the instantaneous heat generated by high-rate charging and discharging, potentially leading to overheating, frequency throttling, or battery life degradation. Furthermore, deploying the solar panel and activating the cooling system often require separate operations, increasing usage steps and reducing overall energy efficiency. The design of the cooling ducts lacks adequate airflow optimization, resulting in a simplistic airflow guide structure that negatively impacts heat dissipation. In addition, the device lacks stability when tilted, and the absence of integrated support and adjustment mechanisms limits its applicability in complex terrain. Adjusting the angle of the deployed solar panel also largely relies on manual fixing, failing to establish effective linkage support with the device itself. Summary of the Invention

A mechanical linkage mechanism seamlessly integrates the unfolding of the solar panel assembly with the opening of the air-cooling system's air intake and the start of the fan. Users only need to unfold the solar panel to automatically open the air inlet and start the cooling fan, requiring no additional operation.

[0024] 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.

[0025] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] As attached Figures 1 to 8 The illustrated solar-powered outdoor portable power supply, when the solar panel assembly 4 moves from a folded state to an unfolded state, the base plate 401 and the extension plate 402 unfold via a connecting hinge to form a light-receiving plane. At this time, the first hinge seat 602 fixed to the extension plate 402 displaces with the unfolding action, driving the linkage rod 601 to move in a plane via the first pin 604. The other end of the linkage rod 601 pushes the second hinge seat 603 via the second pin 605, causing the air guide plate 503 to rotate around its axis and open the air inlet. Simultaneously, the unfolding movement of the extension plate 402 causes the trigger cam 610 to rotate synchronously. When a predetermined unfolding angle is reached, the trigger cam 610 presses the contacts of the micro switch 609 to connect the fan 502 circuit. At this time, the return spring 606 is stretched and stores energy, which applies a continuous closing torque to the air guide plate 503 via the spring lug 608.

[0028] When fan 502 starts, airflow flows along duct 501. Guide fins 506 within duct 504 optimize airflow distribution, and a protective mesh 505 prevents foreign objects from entering. Heat generated by battery pack 2 is conducted to heat dissipation fins 8 via heat-conducting bracket 7. Heat dissipation fins 8 release heat into the airflow through duct 501 for cooling. Support mechanism 9 adjusts the device tilt angle via support rod 901, and locking knob 902 fixes the support angle to maintain optimal solar panel orientation. Control circuit 3 monitors battery pack 2 temperature in real time via temperature sensor 303, and charging management integrated circuit 302 dynamically adjusts charging parameters based on temperature data.

[0029] When the solar panel assembly 4 is folded, the extension plate 402 retracts via the connecting hinge. The first hinge seat 602 drives the linkage rod 601 to move in the opposite direction. The reset spring 606 releases its elastic potential energy, pulling the guide plate 503 to close the air inlet. This triggers the cam 610 to separate from the micro switch 609, cutting off the circuit of the fan 502 and completing the system reset. Throughout the process, the limit rotation shaft 403 and the limit baffle 404 work together to control the unfolding angle, the anti-slip pad 104 ensures the stability of the equipment, and the handle 103 provides a convenient carrying function. All components work together through mechanical linkage and electrical control.

[0030] Specifically, the unfolding motion of the solar panel assembly 4 is converted into the opening motion of the guide plate 503 via the mechanical linkage mechanism 6: when the extension plate 402 rotates around the limiting rotation shaft 403, the first hinge seat 602 at its edge moves in an arc, transmitting power to the second hinge seat 603 on the guide plate 503 via the linkage rod 601. Since the second hinge seat 603 is fixed at a non-central position of the guide plate 503, the linear push-pull motion of the linkage rod 601 is converted into the rotational motion of the guide plate 503. This transmission design ensures that the solar panel unfolding angle is proportional to the opening degree of the guide plate 503, guaranteeing that the heat dissipation system starts synchronously with the power generation system. The cooperation between the limiting baffle 404 and the limiting rotation shaft 403 precisely controls the maximum unfolding angle, preventing over-unfolding and structural damage.

[0031] The air-cooled system operates as follows: After the air deflector 503 opens, it forms an air intake channel. Simultaneously, the microswitch 609 is triggered, activating the fan 502. The fan 502 generates negative pressure, drawing external air through the air deflector 503 into the flow channel 504. The guide fins 506 on the wall of the flow channel 504 direct the airflow towards the densely packed area of ​​the heat dissipation fin assembly 8. The heat-conducting bracket 7 evenly transfers heat from the battery pack 2 to the heat dissipation fin assembly 8, and the hydrophilic coating on the fin surface enhances heat exchange efficiency. The protective mesh 505 forms a protective barrier at the air inlet, and its quick-release structure facilitates regular cleaning and maintenance. This multi-stage, interconnected cooling design ensures the equipment maintains a stable temperature even at high power output.

[0032] The linkage between the support mechanism 9 and the solar panel assembly 4 is as follows: when the support rod 901 adjusts the tilt angle of the equipment, the light-receiving angle of the solar panel assembly 4 changes synchronously. The locking knob 902 locks the angle of the support rod 901 through a ratchet mechanism, and the capillary drainage structure of the anti-slip pad 104 ensures the stability of the equipment at different tilt angles. This linkage design ensures that the solar panel always maintains the optimal orientation, maximizing the light energy conversion efficiency.

[0033] Temperature sensor 303 collects real-time temperature data from battery pack 2, and charging management integrated circuit 302 dynamically adjusts the charging current based on temperature changes. When the temperature exceeds a threshold, circuit board 301 can increase the speed of fan 502 to enhance heat dissipation; when the temperature returns to normal, the system automatically reduces the speed of fan 502 to save energy. This intelligent linkage management ensures charging safety while optimizing energy utilization efficiency.

[0034] When the solar panel assembly 4 is folded, the extension plate 402 retracts, causing the first hinge seat 602 to reset, and the linkage rod 601 releases the thrust on the guide plate 503. At this time, the elastic potential energy of the reset spring 606 is released, pulling the guide plate 503 to close the air inlet through the spring lug 608. Simultaneously, the trigger cam 610 disengages from the micro switch 609, cutting off the circuit of the fan 502 and stopping its operation. This reverse linkage ensures that the equipment is completely sealed when not in operation, effectively preventing dust intrusion and component aging.

[0035] The deployment of the solar panel simultaneously triggers the opening of the air guide plate 503 and the start of the fan 502. The heat dissipation system automatically adjusts according to the battery temperature, the support mechanism 9 maintains the optimal working posture, and the control circuit 3 coordinates the operation of the entire system. This multi-system collaborative design achieves an organic unity of energy harvesting, thermal management, and structural stability, significantly improving the reliability and efficiency of the equipment in outdoor environments.

[0036] Example 2

[0037] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 8 As shown below, see details: The linkage rod 601 is designed as a telescopic structure to adapt to transmission requirements at different deployment angles. The surface of the linkage rod 601 is treated with anti-corrosion to improve its outdoor service life. The first hinge seat 602 is fixed to the edge of the substrate 401 of the solar panel assembly 4 by bolt connection. The second hinge seat 603 is welded to the reinforcing rib of the guide plate 503 to enhance the connection strength. Both the first pin 604 and the second pin 605 are equipped with anti-dislodgement snap rings to ensure hinge reliability. A spherical bearing is provided at the connection between the linkage rod 601 and the first hinge seat 602 to accommodate small displacements in multiple dimensions. The connection of 603 adopts a copper bushing structure to ensure smooth rotation. When the solar panel assembly 4 is unfolded, the linkage rod 601 generates a pulling force through the first hinge seat 602, which pulls the second hinge seat 603 to open the guide plate 503 outward. When the solar panel assembly 4 is folded, the linkage rod 601 generates a pushing force through the first hinge seat 602, which pushes the second hinge seat 603 to close the guide plate 503 inward under the action of the return spring 606. An eccentricity is set between the rotation axis of the guide plate 503 and the installation position of the second hinge seat 603 to produce a force-saving effect. The movement trajectory of the linkage rod 601 is limited by the guide groove to prevent movement interference.

[0038] Furthermore, the return spring 606 is made of multi-strand wound piano wire to provide a stable elastic coefficient. The bottom of the spring fixing post 607 is injection molded into the outer shell 1 to ensure connection strength. The connection between the spring lug 608 and the guide plate 503 is chamfered to avoid stress concentration. The end of the return spring 606 is bent to form a hook-like structure to enhance the reliability of the hook. The surface of the spring fixing post 607 is polished to reduce frictional loss with the return spring 606. When the guide plate 503 is extended under the pull of the linkage rod 601, the return spring 606 gradually stretches as the spring lug 608 moves. The spring force acts on the guide plate 503 through the spring lug 608 to generate a continuous closing torque. When the linkage rod 601 releases the pull on the guide plate 503... When the force is applied, the return spring 606 drives the guide plate 503 to rotate around the pivot to the fully closed position. The installation angle of the spring lug 608 is optimized to ensure that the direction of the spring force is always tangent to the movement trajectory of the guide plate 503. A limit ring is provided around the return spring 606 to prevent the spring from being overstretched and causing plastic deformation. A heat dissipation fin group is designed around the spring fixing post 607 to accelerate the dissipation of heat when the spring is working. A rotary bearing is provided at the connection between the spring lug 608 and the return spring 606 to allow the spring to rotate freely during operation and avoid torque accumulation. The extension and retraction stroke of the return spring 606 is mechanically limited by the stroke limit block provided inside the outer shell 1. The installation position of the spring fixing post 607 avoids the main airflow path in the air duct 501 to reduce airflow resistance.

[0039] Furthermore, the micro switch 609 adopts a waterproof sealing structure to adapt to outdoor use environments. The connection between the trigger cam 610 and the solar panel assembly 4 is equipped with an adjustment elongated hole for precise adjustment of the trigger position. The inner wall of the switch mounting groove 611 is provided with guide ribs to ensure the micro switch 609 is properly installed. The contact surfaces between the contacts of the micro switch 609 and the trigger cam 610 are made of wear-resistant material to improve service life. The working curved surface of the trigger cam 610 is precisely calculated to have progressive triggering characteristics. As the solar panel assembly 4 unfolds, the trigger cam 610 rotates with the assembly and gradually approaches the micro switch 609. When the predetermined unfolding angle is reached, the protruding part of the trigger cam 610 presses against the contact arm of the micro switch 609, causing the internal spring of the micro switch 609 to deform and achieve circuit conduction. The switch mounting groove 611... 1. A waterproof rubber ring is provided at the bottom to prevent moisture intrusion. The lead wire of the micro switch 609 is neatly routed through a wire groove and connected with a plug-in terminal. A counterweight is provided on the back of the trigger cam 610 to ensure motion balance. The trigger pressure of the micro switch 609 is optimized by adjusting the curvature of the trigger cam 610. Heat dissipation holes are provided around the switch mounting slot 611 to dissipate the heat generated by the micro switch 609 during operation. The contact point between the trigger cam 610 and the micro switch 609 is coated with grease to reduce friction loss. The force of the return spring 606 of the micro switch 609 is matched with the pressure characteristics of the trigger cam 610 to ensure trigger reliability. When the solar panel assembly 4 is folded, the trigger cam 610 and the micro switch 609 gradually separate, and the internal spring of the micro switch 609 returns to its original state to automatically cut off the fan 502 circuit.

[0040] Furthermore, a shock-absorbing pad is provided at the connection between the base plate 401 and the outer shell 1 to buffer vibration and impact. Reinforcing ribs are arranged on the back of the extension plate 402 to improve structural rigidity. A rolling bearing is installed inside the limiting rotation shaft 403 to ensure smooth rotation. Wear-resistant material is inlaid on the working surface of the limiting baffle 404 to extend its service life. The surface of the base plate 401 is embossed to enhance anti-slip performance. Chamfers are provided at the edges of the extension plate 402 to prevent scratches. A waterproof sealing ring is provided at the end of the limiting rotation shaft 403 to prevent water ingress. The limiting baffle 404 is connected to the outer shell 1 in an adjustable manner for easy angle calibration. When the extension plate 402 is extended, it rotates around the limiting rotation shaft 403. Plate 404 limits the rotation range by mechanical blocking. The base plate 401 and the extension plate 402 are electrically connected by a flexible wire. After the extension plate 402 is unfolded, it forms a continuous light-receiving plane with the base plate 401. A torsion spring is set inside the limiting rotation shaft 403 to assist the unfolding action. A buffer layer is set on the contact surface of the limiting baffle 404 to reduce impact noise. A positioning pin is set at the installation position of the base plate 401 to ensure assembly accuracy. The surface of the extension plate 402 is coated with a self-cleaning coating to reduce dust adhesion. An angle scale mark is set on the limiting rotation shaft 403 to intuitively display the opening and closing angle. The limiting baffle 404 adopts a visual design to facilitate observation of the working status.

[0041] Furthermore, the flow channel 504 adopts a tapered cross-section design to accelerate airflow. The protective net 505 is woven from stainless steel and treated with anti-corrosion measures. The guide fins 506 are arranged radially and use an airfoil profile to reduce flow resistance. The inner wall of the flow channel 504 is polished to reduce surface roughness. The protective net 505 is easy to disassemble and clean using a snap-on structure. The guide fins 506 and the wall of the flow channel 504 are integrally molded to ensure structural strength. A guide plate 503 is installed at the bend of the flow channel 504 to eliminate vortex phenomena. The mesh size of the protective net 505 is calculated to prevent foreign objects from entering without affecting ventilation efficiency. The height of the flow fins 506 gradually changes along the airflow direction to maintain boundary layer stability. A rain baffle is provided at the inlet of the flow channel 504 to prevent liquid backflow. A shock-absorbing pad is added to the back of the protective net 505 to reduce resonance noise. The surface of the flow fins 506 is coated with a thermally conductive material to enhance heat dissipation. A sealing strip is used at the connection between the flow channel 504 and the outer shell 1 to ensure airtightness. The edges of the protective net 505 are rolled to prevent scratches. The ends of the flow fins 506 are provided with turbulence teeth to enhance airflow mixing. A temperature sensor 303 is installed inside the flow channel 504 to monitor the operating condition of the air duct 501. An antifreeze device can be added to the protective net 505 to prevent icing in winter from affecting ventilation.

[0042] Furthermore, the heat-conducting bracket 7 is die-cast from aluminum alloy and anodized on the surface. The heat dissipation fin assembly 8 is composed of multiple layers of thin aluminum sheets with the spacing between the sheets optimized by hydrodynamics. Thermal grease is applied to the contact surface between the battery pack 2 and the heat-conducting bracket 7 to reduce contact thermal resistance. One end of the heat dissipation fin assembly 8 is connected to the heat-conducting bracket 7, and the other end extends into the air duct 501. An interlocking fixing structure is adopted so that the airflow passing through the air duct 501 can pass over the surface of the heat dissipation fin assembly 8 for heat exchange.

[0043] The heat-conducting bracket 7 has mounting lugs on its edge, which are connected to the base of the outer shell 1 via anti-loosening bolts. The portion of the heat dissipation fin assembly 8 extending into the air duct 501 is arranged in a wave-like pattern to enhance the turbulence effect. The heat generated by the battery pack 2 is quickly conducted to the heat dissipation fin assembly 8 through the heat-conducting bracket 7. The heat dissipation fin assembly 8 accelerates heat dissipation by increasing the contact area with the airflow. A temperature sensor 303 is embedded inside the heat-conducting bracket 7 to monitor the operating temperature of the battery pack 2 in real time. The surface of the heat dissipation fin assembly 8 is treated with black paint to improve the radiation heat dissipation efficiency. An elastic heat insulation pad is set at the contact point between the heat-conducting bracket 7 and the outer shell 1 to prevent reverse heat conduction. The arrangement of the heat dissipation fin assembly 8 in the air duct 501 avoids airflow dead zones to ensure heat dissipation effect. The heat-conducting bracket 7 has multiple positioning posts to ensure accurate installation of the battery pack 2. The ends of the heat dissipation fin assembly 8 adopt a flanged design to increase structural rigidity. Auxiliary heat dissipation fins are arranged on the back of the heat-conducting bracket 7 to form a double-sided heat dissipation structure.

[0044] Furthermore, the circuit board 301 is made of glass fiber substrate and treated with a moisture-proof coating. A heat sink is mounted on the surface of the charging management integrated circuit 302 and it contacts the housing 1 via thermally conductive adhesive. The temperature sensor 303 is mounted on the circuit board 301, and its probe is thermally coupled to the battery pack 2 via a thermally conductive material. Multiple mounting holes are provided along the edge of the circuit board 301, and it is fixed to the housing 1 via insulating gaskets. A group of filter capacitors is arranged around the charging management integrated circuit 302 to ensure operational stability. The probe of the temperature sensor 303 is tightly attached to the surface of the battery pack 2 via thermally conductive silicone. The wiring layer of the circuit board 301 is optimized to reduce electromagnetic interference. The charging management integrated circuit 302 has… The multi-stage charging mode can automatically adjust parameters according to the temperature signal. The data line of the temperature sensor 303 is shielded to prevent signal distortion. The front of the circuit board 301 is covered with a conformal coating to resist environmental corrosion. The charging management integrated circuit 302 and the temperature sensor 303 exchange data through a digital bus. Test points are set on the back of the circuit board 301 to facilitate fault diagnosis. The temperature sensor 303 has a self-calibration function to ensure measurement accuracy. The charging management integrated circuit 302 drives the on / off of the fan 502 circuit to achieve intelligent temperature control. The power input terminal of the circuit board 301 is equipped with an overvoltage protection element. The data monitored by the temperature sensor 303 is displayed on the external indicator light in real time.

[0045] Furthermore, the joint between the bottom shell 101 and the top shell 102 adopts a labyrinth-style sealing structure to enhance waterproof performance. The anti-slip pad 104 is made of high-friction rubber and is reliably connected to the bottom shell 101 through a buckle.

The bottom of the anti-slip pad 104 is designed with drainage grooves to prevent water accumulation and slippage. When the handle 103 is folded up, it fits the contour of the top shell 102 without taking up extra space. The front cover 102 is secured with concealed quick-release screws for easy maintenance. The anti-slip pad 104 is installed in a position calculated by the center of gravity to ensure stability. The handle 103 has a soft pad inside to improve grip comfort. The edges of the front cover 102 are rounded to prevent scratches. The bottom cover 101 has lifting feet at the four corners to ensure ventilation space at the bottom. When the handle 103 is unfolded, it is automatically locked at the optimal angle by a limiting mechanism. The bottom cover 101 is made of flame-retardant engineering plastic to meet safety standards. The anti-slip pad 104 is detachable for easy replacement of worn parts. The handle 103 has a waterproof bearing at the pivot to ensure smooth operation over long-term use.

[0046] Furthermore, the support rod 901 is connected to the bottom of the outer casing 1 via a hinge point, and adopts a telescopic multi-section structure to achieve stepless height adjustment. The locking knob 902 has a nylon anti-loosening washer inside to prevent accidental loosening. The hinge of the support rod 901 uses a copper-based self-lubricating bearing to ensure smooth rotation. The end of the support rod 901 is equipped with an anti-sinking foot to increase the ground contact area. The surface of the locking knob 902 is knurled to enhance the operating friction. When the support rod 901 is retracted, it stays in contact with the bottom surface of the outer casing 1 through a magnetic attraction device. The threaded part of the locking knob 902 is rust-proofed to adapt to outdoor environments. After unfolding, the support rod 901 forms a triangular support structure to enhance stability. The contact surface between the locking knob 902 and the support rod 901 has textured surfaces to increase friction. A grip groove is provided in the middle section of the support rod 901 for easy operation. The locking knob 902 has a built-in limiting mechanism to prevent over-tightening and damage to the threads. The angle adjustment range of the support rod 901 is controlled by a physical limiting block. The locking knob 902 uses color to indicate different locking states. The internal wiring of the support rod 901 accommodates the solar panel extension cable. The operating direction of the locking knob 902 and the movement trajectory of the support rod 901 conform to ergonomics.
