Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of backpacks, and particularly to a solar backpack. Background Art
[0002] The key component of a solar backpack is an internal or external solar panel, which usually adopts monocrystalline silicon, polycrystalline silicon or flexible thin-film solar cell materials. Among them, the monocrystalline silicon solar panel has a relatively high photoelectric conversion efficiency and can convert solar energy into electrical energy more efficiently under certain lighting conditions; while the flexible thin-film solar panel has better flexibility, can adapt to the bending and folding of the backpack surface, and is convenient for carrying and using.
[0003] However, such designs have obvious limitations: the exposed solar panels are vulnerable to external force impacts and may break. The mainstream solar panels (such as crystalline silicon cells) use silicon wafers as the core photoelectric conversion layer, and their Mohs hardness is 6.5 - 7 (glass is 5.5). Although the surface is covered with tempered glass (hardness 7) for protection, the silicon wafer is still a brittle material in nature. When subjected to local impacts (such as stone impacts or point loads generated by dropping), the stress concentrates at the impact point. When the stress exceeds the bending strength of the silicon wafer (≥150 MPa), microcracks will be generated, and the cracks will spread along the crystal cleavage plane, resulting in fragmentation.

A protective shell 20 is placed in the sub-storage layer 19, and a transparent cover 21 is placed in the protective shell 20. A buffer mechanism 10 is provided around the protective shell 20;
[0040] The buffer mechanism 10 includes a top plate 101. A docking plate 106 is slidably connected inside the top plate 101. A limit pin 107 is rotatably connected to the middle of the docking plate 106. Limit plates 108 are fixedly connected to both sides of the limit pin 107. One end of the docking plate 106 is fixedly connected to the transparent cover 21. A limit groove 109 is provided in the middle of the top plate 101;
[0041] The limit pin 107 rotates for the docking of the transparent cover 21 and the protective shell 20 to realize the protection of the solar panel 4.
[0042] It should be noted that a non-slip inner lining matching the protective shell 20 is provided in the sub-storage layer 19. One side of the sub-storage layer 19 is provided with a mesh for sunlight to shine through;
[0043] Grooves for the sliding of the top plate 101 are provided around the protective shell 20 to avoid interference;
[0044] The transparent cover 21 is made of a transparent material.
[0045] In the present invention, preferably, the buffer mechanism 10 further includes a bottom plate 100, which is fixedly connected to the middle of the protective shell 20 and damping rods 104 are fixedly connected to the periphery of the surface.
[0046] A spring 105 is sleeved on the damping rod 104.
[0047] A limiting post 103 is fixedly connected inside the limiting post 103.
[0048] A sliding plate 102 slides on the surface of the limiting post 103.
[0049] It should be noted that the bottom plate 100 is arranged in the groove of the secondary storage layer 19.
[0050] In the present invention, preferably, the top plate 101 slides in the protective shell 20, and a limit pin 107 is movably installed in the middle of the docking plate 106.
[0051] The limit pin 107 and the limit plate 108 are slidably connected in the limit groove 109, and ventilation holes 22 are provided on the protective shell 20.
[0052] It should be noted that the shape of the limit groove 109 is adapted to the limit pin 107 and the limit plate 108. If the limit pin 107 and the limit plate 108 rotate and change shape, they cannot be taken out from the limit groove 109.
[0053] The limit plate 108 is arranged between the docking plate 106 and the limit pin 107 to prevent the limit pin 107 from detaching from the docking plate 106.
[0054] The provision of the ventilation holes 22 can not only ventilate but also thread connecting wires.
[0055] In the present invention, preferably, the bottom plate 100 and the top plate 101 are arranged in parallel.
[0056] The other end of the damping rod 104 is connected to the top plate 101, and the sliding plate 102 is slidably connected to the chute opened in the protective shell 20.

[0059] During the implementation process, the solar panel 4 is placed in the protective shell 20, and the transparent cover 21 with the docking plate 106 is placed in the groove in the middle of the top plate 101. The limiting pin 107 and the limiting plate 108 pass through the limiting groove 109. The limiting pin 107 and the limiting plate 108 are rotated to stagger the limiting plate 108 and the limiting groove 109, so that the transparent cover 21 is connected to the protective shell 20 to protect the solar panel 4 and prevent the surface of the solar panel 4 from being contaminated by dust. The transparent cover 21 is made of transparent material, which allows sunlight to pass through and illuminate the solar panel 4 to achieve photoelectric conversion, and also protects the solar cells.
[0060] The solar panel 4 enclosed by the protective shell 20 and the transparent cover 21 is placed in the secondary storage layer 19. When the transparent cover 21 is squeezed, the transparent cover 21 and the docking plate 106 squeeze the top plate 101. The top plate 101 and the sliding plate 102 move downward along the sliding groove formed by the limiting column 103 and the protective shell 20, and are buffered by the damping rod 104 and the spring 105, which can effectively improve the protective effect of the transparent cover 21.
[0061] Example 2
[0062] In the present invention, preferably, the bag body 1 further includes a handle 2 fixed to the upper portion of the bag body 1 , an S-shaped simulated shoulder strap 3 connected to both sides of the bag body 1 , and a main storage layer 15 located inside the bag body 1 .
[0063] It should be noted that the handle 2 is made of thickened PU leather with a non-slip texture on the surface, providing short-distance carrying function to meet the needs of quick access; the non-slip design ensures grip stability, and is reinforced with the top edge of the bag through high-density stitching, with a flexible steel bar support structure embedded inside.
[0064] In the present invention, preferably, a waterproof zipper 5 is provided at the opening of the main storage layer 15, and the waterproof zipper 5 extends along the top edge of the bag body 1 to the connection of the S-shaped simulated shoulder straps 3 on both sides;
[0065] The S-shaped simulated shoulder strap 3 is provided with a double adjustment buckle 6, which includes two sets of independently adjustable sliding buckles, one upper and one lower.
[0066] It should be noted that the S-shaped simulated shoulder strap 3 is connected to the two sides of the bag body 1 with a Y-shaped force distribution. The material is a composite layer of memory foam and nylon mesh. It is designed to imitate the human shoulder and neck curve to disperse shoulder pressure. The breathable mesh improves long-term carrying comfort. It is connected to the bag body through a metal Japanese buckle. A length adjustment ring is set at the end of the shoulder strap to adapt to users of different heights.
[0067] In the present invention, preferably, side bands 7 are provided on both sides of the bag body 1 , and a detachable interlayer board 16 is provided in the main storage layer 15 .
[0068] In the present invention, preferably, a mesh storage bag 12, a card storage bag 11 and a mesh pocket zipper 18 are provided inside the bag body 1.
[0069] In the present invention, preferably, a charging device storage bag 14 and a USB junction box 13 are provided inside the secondary storage layer 19, and a bottom data line perforation 9 is provided at the bottom of the secondary storage layer 19 for threading a data line to be connected to the USB junction box 13.
[0070] In the present invention, preferably, the bottom data line perforation 9 is embedded with a silica gel wire fixer, which is injection-molded with food-grade liquid silica gel, with a pore diameter of 8 mm ± 0.5 mm, for fixing the data line interface to prevent it from falling off. The silica gel elastomer protects the surface of the wire from abrasion, and is hot-pressed and embedded after opening a hole at the bottom of the bag body, and an annular anti-pulling convex structure is provided inside.
[0071] During the implementation process, a heat-sealed rubber strip is formed at the joint of the waterproof zipper 5 of the main storage layer 15 and the bag body to form a complete waterproof barrier. When the user closes the zipper, the TPU sealing strip inside the zipper head is compressed and expanded, forming a triple waterproof structure with the track, which can achieve the effect of waterproofing and water blocking in a short time;
[0072] After the mobile power supply is placed in the charging device storage bag 14, the data line is led out through the bottom perforation, and the silica gel wire fixer locks the interface position. At this time, the Type-C female socket of the USB junction box 13 is connected to an external device, and the system automatically identifies the load and activates overcurrent protection. During the charging process, the temperature sensor inside the bag body monitors in real time, and automatically cuts off the circuit when it exceeds 45 °C;
[0073] The S-shaped simulation shoulder strap 3 optimizes the curvature radius through finite element analysis, and pressure dispersion convex points are provided at the turning points of the shoulder strap. When the user carries the bag, the pressure in the contact area between the shoulder strap and the collarbone is reduced to below 0.15 MPa (the traditional straight shoulder strap is 0.28 MPa). With the length-curvature linkage mechanism of the double adjustment buckle 6, the weight distribution is more in line with biomechanical characteristics.
[0074] The above has described the embodiments of the present invention in detail, but the above content is only the preferred embodiments of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equal changes and improvements made according to the scope of the present invention application shall still fall within the scope covered by the patent of the present invention.
