Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0029] It should be noted that in the description of this utility model, the terms "upper", "lower", "top", "bottom", "one side", "the other side", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not mean that the device or component must have a specific orientation, or be constructed and operated in a specific orientation.

[0030] See appendix Figure 1-7 The present invention proposes a solar-powered, portable recliner, which includes three sets of outer frames 9, a polymer composite inner panel 4, a solar panel 11, support legs 1, aluminum foil heat sinks 15, and a battery 18.

[0031] Three sets of outer frame frames 9 are arranged adjacent to each other in sequence, and the ends of two adjacent sets of outer frame frames 9 are hinged by rotating hinges 6; the two ends of the rotating hinges 6 are respectively fixed to the ends of the two adjacent sets of outer frame frames 9 by fixing bolts 5.

[0032] In this embodiment, the polymer composite inner plate 4 is a PEEK plastic sheet, capable of withstanding temperatures above 100℃ while also being resistant to low temperatures. It also possesses high strength and rigidity and will not be damaged within a reasonable load-bearing range. The polymer composite inner plates 4 are respectively and correspondingly arranged inside the three sets of outer frame plates 9, with the middle portion of each inner plate 4 rotatably connected to the corresponding outer frame plate 9 via a long cylindrical damping pivot 12. Support legs 1 are rotatably connected to the left and right sides of the outer ends of the outer frame plates 9 at both ends via short cylindrical damping pivots 2, and support legs 1 are rotatably connected to the left and right sides of the front and rear ends of the middle outer frame plate 9 via short cylindrical damping pivots 2. The support legs 1 are rotatably connected to the outer frame plates 9, enabling multi-angle rotation.

[0033] The back of the polymer composite inner panel 4 has a hollowed-out area, which is sealed by the solar panel 11. The hollowed-out area can be machined using a high-precision CNC machining center. First, the hollowed-out area is marked on the panel surface using laser positioning. Then, using a carbide cutting tool with a rotation speed of 3000-5000 rpm, it is milled layer by layer to a depth of 0.5-1 mm, achieving a machining accuracy of ±0.1 mm. After hollowing out, the surface is sanded step by step, and then the solar panel 11 is glued and sealed with high-temperature resistant waterproof sealant. The sealant thickness is controlled at 0.3-0.5 mm, and after curing, a waterproof structure is formed.

[0034] The aluminum foil heat sink 15 and the battery 18 are arranged sequentially from top to bottom within the hollowed-out area of ​​the polymer composite inner plate 4 and are interconnected. The battery 18 is fixed inside the polymer composite inner plate 4 by a battery frame 19. A mineral wool insulation layer 14 is provided between the aluminum foil heat sink 15 and the battery 18, effectively isolating the 40-50℃ heat generated by the heating element and preventing heat transfer to the battery 18 and causing damage. In this embodiment, the battery 18 has a capacity of 20Ah and provides a low voltage of 24V. The battery is adjacent to the 20mm thick mineral wool insulation layer 14 and connected to the positive and negative terminals of the aluminum foil heat sink 15 above the mineral wool insulation layer 14. The solar panel 11 is connected to the battery 18 to charge it. When the battery 18 has sufficient power, it can supply power to the aluminum foil heat sink 15; when the power is insufficient, the solar panel 11 can be charged by flipping the polymer composite inner plate 4 so that it faces upwards.

[0035] Each polymer composite inner plate 4 contains a battery 18 that can provide 50W of power, and three batteries 18 can provide 150W of power.

[0036] The aluminum foil heat sink 15 is composed of carbon fiber heating wire 15a and knitted non-woven fabric 15b. The carbon fiber heating wire 15a is evenly coiled on the upper part of the mineral wool insulation layer 14 in an S-shaped structure. The knitted non-woven fabric 15b is sleeved on the outside of the carbon fiber heating wire 15a and is attached to it for insulation.

[0037] When installing the aluminum foil heat sink 15, the layout of the S-shaped heating wires with a spacing of 22mm is first determined using CAD layout. The carbon fiber heating wire 15a is then fixed using ultrasonic welding, and an insulation test of over 100MΩ is performed after welding. Next, silicone with a thermal conductivity of 3.5W / (m·K) is used to adhere it to the mineral wool insulation layer 14, and L-shaped clips are used for fixation. The aluminum foil heat sink 15 uses an S-shaped arrangement of heating wires. Due to its relatively dense arrangement and a 22mm spacing between the heating wires, it can quickly heat up and release heat to heat the seat, providing 40-50℃ of heat. A temperature sensor 13 is placed on the carbon fiber heating wire 15a to monitor the temperature and transmit the monitored temperature to the temperature controller 10.

[0038] In this embodiment, the aluminum foil heat sink 15 is sequentially covered with an aluminum foil reflective film 17 and a silicone waterproof sleeve 16 to achieve a waterproof effect.

[0039] A temperature sensor 13 is installed on the aluminum foil heat sink 15, and a temperature controller 10 is installed on the uppermost outer frame 9. The temperature controller 10 is connected to the temperature sensor 13 and the battery 18. Each circuit is connected to the external temperature controller 10 to achieve automatic temperature adjustment. The temperature controller 10 has a built-in STM32 microprocessor and uses a PID control algorithm. When the temperature sensor 13 detects that the actual temperature is lower than the set value, the microprocessor increases the circuit current through a PWM pulse signal; when the temperature reaches or exceeds the set value, the current decreases, achieving constant temperature control with an accuracy of ±1℃. The polymer composite inner plate 4 can be heated under low voltage (24V).

[0040] The thermostat 10 has four settings: on, off, heat up, and cool down. During operation, the user sets the target temperature using these settings. Based on feedback from the temperature sensor 13, the thermostat adjusts the output current at a frequency of [number] times per second. For example, if the temperature is set to 45℃, the current increases when the actual temperature is below 44℃ and decreases when it is above 46℃ to maintain a stable temperature. The thermostat 10 can adjust the current to regulate the temperature of the heat sink, allowing the user to rest at a comfortable temperature.

[0041] In this embodiment, fixing hooks 7 are welded to the left and right sides of one end of the outer frame 9. When in seat mode, to withstand the force of a large human body, an adjustable chain 8 connects the two fixing hooks 7 on adjacent outer frames 9 for fixation. When fully unfolded and folded, the adjustable chain 8 can be removed to allow free flipping. Hook rings 3 are rotatably connected to both ends of the outer surface of one side of the polymer composite inner plate 4, which can hook with the fixing hooks 7 on the outer frame 9 to prevent tipping.

[0042] In this embodiment, a USB interface 20 connected to the battery 18 is provided on one side of the outer frame 9, which can be connected to an external charging device to charge the battery 18 as a second power source.

[0043] This utility model can freely transform the form of a seat or bed. When the outer frame 9 is completely folded, the three outer frames 9 can be attached in sequence and can be easily carried into a portable case.

[0044] All matters not detailed in this utility model are common knowledge.

[0045] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
