Under the scorching sun, covering the first aid blanket on the body can protect the body from direct sunlight. When encountering cold weather in the wild, wrapping the first aid blanket around the body can absorb heat and reduce heat loss from the body.
[0003] However, the existing first aid blankets do not have the function of generating electricity. Especially in outdoor situations, with the continuous update and replacement of electronic devices, electronic devices have gradually become necessities of life. In the wild, it is very easy for the devices to run out of power, and it is inconvenient to obtain a power source in the wild, resulting in the devices being unable to be used.

[0017] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.
[0018] Please refer to Figure 1 , this embodiment provides a solar first aid blanket, including a first aid blanket 1 made of aluminum film. The first aid blanket 1 can also be made of tin foil paper, and its material is the same as that of the common first aid blanket 1. Both sides of the first aid blanket 1 are silver, or both sides are silver, or one side is silver and the other side is gold.
[0019] In this embodiment, the first aid blanket 1 adopts a design with one gold side and one silver side. A plurality of through holes 2 are opened at the edge of the first aid blanket 1, and a metal ring is press-fitted inside the through holes 2. The metal ring wraps the inner side of the through holes 2, making the through holes 2 have sufficient strength. When spreading out the first aid blanket 1, fingers are buckled inside the metal ring to avoid damage to the through holes 2 when spreading out the first aid blanket 1, as Figure 1 shown.
[0020] A thin-film solar panel 3 is arranged on the outer side of the first aid blanket 1, as Figure 1 shown. The thin-film solar panel 3 is arranged on the silver side, as Figure 1As shown in the figure. The thin-film solar panel 3 adopts amorphous silicon thin-film solar cells, copper indium gallium selenide thin-film solar cells (CIGS), and cadmium telluride thin-film solar cells (CdTe), and is set in the middle of the first aid blanket 1. The technology of multi-layer composite vacuum hot pressing and fusing is adopted between the thin-film solar panel and the first aid blanket, which has the characteristics of waterproof, dustproof, and abrasion-proof. When unfolding the first aid blanket 1 for charging, the rope can be tied to the metal ring (or different metal rings can be hung on the tree branches to keep the first aid blanket 1 in an open state). When the first aid blanket 1 is in an open state, the thin-film solar panel 3 is aligned with the sun, and the thin-film solar panel 3 can be used for charging.
[0021] As Figure 1 and Figure 2 As shown in the figure, a lithium battery 7 is fixedly installed on one side edge of the first aid blanket 1, and a lithium battery 7 is adhesively fixed at the back. The lithium battery 7 is connected to the thin-film solar panel 3, and the thin-film solar panel 3 is used to charge the lithium battery 7.
[0022] A housing is arranged outside the lithium battery 7, and a 5V photovoltaic controller (such as DFRO558 solar power management module) or a 12V photovoltaic controller is also arranged inside the housing. The 5V or 12V photovoltaic controller directly connects the output of the thin-film solar panel 3 to the lithium battery 7 port to charge the lithium battery 7. A charging port 6 is arranged on the housing, and the charging port 6 is used to output 5V voltage and 3A current. According to actual use requirements, the lithium battery 7 charges electronic products such as mobile phones, cameras, power banks, and LED flashlights; it can fully meet the needs in outdoor activities. The appropriate size can also be selected according to actual use requirements, which will not be elaborated here.
[0023] A positive connection port 4 and a negative connection port 5 are also installed on the housing of the lithium battery 7. As Figure 1 - Figure 2 shown in the figure, one edge of the first aid blanket 1 is wound into a hole-shaped structure, and two positive and negative connection wires 8 are installed in the hole. The positive and negative connection wires 8 can be taken out from the hole. The positive and negative connection wires 8 are used to connect the positive and negative poles of the lithium battery 7 on two first aid blankets 1, and can connect the positive and negative poles of the lithium battery 7 on the first aid blanket 1 in series, so as to meet the use requirements of different voltages.
[0024] This product not only has good heat insulation or cold insulation performance and the advantage of being completely waterproof, but also can generate emergency power to charge electronic products such as mobile phones, cameras, power banks, and LED flashlights; it can fully meet the needs in outdoor activities.
[0025] This first aid blanket can be used as a tent cover. The thin-film solar panel 3 faces the sun, and solar energy can be converted into electricity. Just connect the charging cable of the electronic device to the charging port 6 to supply power to the electronic product. If the tent is relatively high, an extended wire can be used to transmit electricity.
[0026] Since the silver coating can reflect heat, covering such a reflective film under the hot sun in summer can keep the tent cool; when camping outdoors in the cold winter, covering the tent with this reflective film can reflect most of the heat emitted by the human body back into the tent, raising the temperature inside the tent. It provides an extra barrier for the tent in hot summer or cold winter.
[0027] It can also be used as a tent groundsheet, laid on the ground inside the tent to prevent contact with damp and cold.
[0028] When using the emergency blanket as a tent cover, pass the connecting rope through the metal ring and tie it to the metal ring to fix the four corners of the emergency blanket. Tighten the tie rope and tie it to the tent to install the emergency blanket. The metal ring facilitates the installation of the emergency blanket. External installation parts such as ropes are directly set on the metal ring, which can avoid damage to the emergency blanket.
[0029] The metal ring is preferably made of magnet material. When folding the emergency blanket, after folding in half, the metal rings can directly adsorb together, thus aligning the edges of the emergency blanket and facilitating the folding of the emergency blanket.
[0030] When the emergency blanket is used as a tarpaulin, multiple emergency blankets can also be laid together. When laying, the edges of the two adjacent emergency blankets are pressed together, so that the metal rings at the pressing part of the two emergency blankets 1 adsorb together, facilitating the laying of the emergency blanket 1. After the emergency blanket is laid, directly pass the rope through the metal ring to fix the emergency blanket. For the pressing part, the rope is passed through the overlapping metal rings, which can realize the fixing of the two metal rings together.
[0031] Creases are pressed on the emergency blanket 1, such as Figure 1 and Figure 2 shown. The creases are rectangular structures, and the size of each crease is just the same as the size of the lithium battery 7, or slightly larger than the size of the lithium battery. When folding, the emergency blanket 1 can be folded into a shape similar to the size of the lithium battery 7 and folded together with the lithium battery 7, which is convenient for folding and storing the emergency blanket.
[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
