Description

Technical Field

[0001] The utility model relates to the technical field of solar foldable bags, in particular to a solar foldable bag. Background Art

[0002] A solar backpack is a foldable solar power generation product that typically includes multiple foldable light-emitting units. It can be folded for easy storage and carry, and unfolded when in use. To ensure optimal absorption of sunlight, existing foldable solar backpacks often feature a stand to provide optimal sunlight exposure.

[0003] Existing foldable solar bags typically have a support frame installed on the side of the solar bag, which is used to support the solar bag on the ground or other flat surface when unfolded. This type of support frame is generally fixed to the solar bag by connecting it with an elastic band or limiting it with a limiter. However, the elastic band of this type of support frame is generally pre-set at the connection position, and is fixed by the maximum opening position of the elastic band. When the opening angle of the support frame needs to be changed, the elastic band cannot be tightened, resulting in instability of the support frame, and the opening angle of the support frame cannot be adjusted. Using a limiter to fix the support frame also maintains stability only when it is in the supporting position. The support frame is also unstable at other opening angles. In addition, the limiter is easily damaged or loosened, resulting in a loss of fixing ability, and the service life cannot be guaranteed. Utility Model Content

[0004] The present invention aims to at least partially address one of the problems in the related art. To this end, one of the objectives of the present invention is to provide a foldable solar bag that allows the support frame of the foldable solar bag to be opened at an adjustable angle, allowing for different placement angles while maintaining stability at different opening angles. The foldable solar bag utilizes a mutual elastic force as a limiting force, avoiding the use of mechanical devices and increasing its service life.

[0005] A solar foldable bag, comprising:

[0006] plate body;

[0007] a support plate, one end of which is rotatably connected to the plate body;

[0008] a first elastic band, one end of the first elastic band being connected to the plate body, and the other end being connected to a side of the support plate away from the support plate;

[0009] A second elastic band, one end of the second elastic band is connected to a side of the support plate close to the support plate, and the other end is connected to a movable part, and the movable part is movably sleeved on the first elastic band.

[0010] Furthermore, the movable part is a movable buckle.

[0011] Furthermore, the second elastic band is further provided with an elastic buckle, which is connected to the second elastic band, and the other end of the second elastic band is passed through the movable part and connected to the elastic buckle.

[0012] Furthermore, the first elastic band and the second elastic band are made of nylon, polyester, silicone or thermoplastic polyurethane.

[0013] Furthermore, the support plate further includes a rotating shaft, both ends of the rotating shaft are connected to the plate body, and the side surface of the rotating shaft is rotatably connected to the support plate.

[0014] Furthermore, the solar foldable bag further comprises a Velcro, wherein the sub-surface of the Velcro is arranged on the plate body, and the main surface of the Velcro is arranged on a side of the support plate away from the plate body.

[0015] Furthermore, two ends of the first elastic band are respectively arranged close to the sub-surface of the Velcro and the main surface of the Velcro.

[0016] Furthermore, the support plate is made of polyester fiber, polycarbonate or nylon.

[0017] Furthermore, the width of the support plate is greater than the width of the first elastic band.

[0018] Furthermore, a handle is provided on the top of the board.

[0019] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0020] The present application comprises a plate body, a support plate, a first elastic band, and a second elastic band. One end of the support plate is rotatably connected to the plate body, allowing the support plate to be rotated open or closed. One end of the first elastic band is connected to the plate body, and the other end is connected to a side of the support plate away from the support plate. One end of the second elastic band is connected to a side of the support plate close to the support plate, and the other end is connected to a movable member, which is movably sleeved on the first elastic band. When the support plate is opened, the first and second elastic bands are simultaneously tensioned. When the solar foldable bag is placed on the ground or other flat surface, the bottom two sides of the plate body and the other end of the support plate serve as three fulcrums to achieve a support effect. The first and second elastic bands also have a mutually pulling and stabilizing effect on the two ends of the support plate and the plate body, maintaining the stability of the placement action. Furthermore, the movable part on the second elastic band can change the position of contact with the first elastic band, thereby not only changing the opening angle of the support plate and maintaining the stability of the placement after the angle is changed, but also maintaining the interactive tensioning effect between the first elastic band and the second elastic band, keeping the first elastic band and the second elastic band in tension after the support plate is opened, thereby maintaining the mutual tension between the support plate, the first elastic band and the second elastic band during placement, and achieving overall stability. In summary, the solar foldable bag of the present application realizes that the opening angle of the support frame of the solar foldable bag is adjustable, achieving different placement tilt angles, and maintaining stability when placed at different opening angles. The mutual elastic force is used as the limiting force, avoiding the use of machinery, and improving the service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0032] like Figure 1 - Figure 4 As shown, the present application provides a foldable solar bag 1, comprising:

[0033] plate body 10;

[0034] A support plate 20, one end of which is rotatably connected to the plate body 10;

[0035] A first elastic band 30, one end of the first elastic band 30 is connected to the plate body 10, and the other end is connected to the side of the support plate 20 away from the support plate 20;

[0036] The second elastic band 40 has one end connected to the side of the support plate 20 close to the support plate 20 , and the other end connected to a movable member 41 , which is movably sleeved on the first elastic band 30 .

[0037] As the carrier of the solar panel, the panel 10 not only carries the heavy responsibility of photoelectric conversion but also cleverly connects to the support plate 20, together forming a stable support structure. One end of the support plate 20 is connected to the panel 10 via a precise rotating connection mechanism. This design allows the support plate 20 to flexibly rotate open or close to the panel 10, easily adapting to the needs of different usage scenarios.

[0038] Next, let's look at the functions of the first elastic band 30 and the second elastic band 40. One end of the first elastic band 30 is firmly fixed to the plate body 10, and the other end is cleverly connected to the side of the support plate 20 away from the support plate 20. When the support plate 20 is opened, the first elastic band 30 responds immediately, and through its elastic force, it generates an outward pulling force on the support plate 20, which helps the support plate 20 to remain stable. The second elastic band 40 further enhances the stability of the entire structure. One end of it is connected to the side of the support plate 20 close to the support plate 20, and the other end is connected to a flexible movable part 41. This movable part 41 is cleverly and movably mounted on the first elastic band 30, and the abutment position with the first elastic band 30 can be adjusted as needed, thereby achieving precise adjustment of the opening angle of the support plate 20.

[0039] By changing the contact position between the movable member 41 and the first elastic band 30, users can not only adjust the opening angle of the support plate 20 as needed to accommodate varying lighting conditions and usage requirements, but also ensure stable placement even after the angle is changed. This stability comes not only from the mutual pulling action between the first and second elastic bands 30 and 40, but also from their all-around stable support of both ends of the support plate 20 and the plate body 10. Even in strong winds or uneven terrain, the solar foldable bag remains rock-solar, ensuring maximum photovoltaic conversion efficiency. Furthermore, this solar foldable bag cleverly avoids the complexity and fragility of traditional mechanical structures. It utilizes mutual elastic force as the limiting force, eliminating the need for complex mechanical transmission components and significantly simplifying the structural design and manufacturing process. This design also improves the product's service life and reliability, reducing maintenance and replacement costs.

[0040] The design of the support plate 20 is equally ingenious. Not only does it structurally coordinate perfectly with the plate body 10 to form a stable support structure, but it is also constructed from a high-strength, corrosion-resistant alloy. This material not only effectively resists the harsh outdoor environment but also maintains stable mechanical properties over extended use, ensuring that the support plate 20 firmly supports the plate body 10.

[0041] The selection of the first and second elastic bands 30 and 40 has also been carefully considered. They are made of high-quality, highly elastic, fatigue-resistant rubber material, ensuring stable elastic properties during extended use. Furthermore, the elastic bands have been specially surface-treated to increase friction with the connecting components, preventing them from loosening or falling off during use.

[0042] The design of movable member 41 further demonstrates the designer's ingenuity. It utilizes a flexible sliding mechanism and locking mechanism, allowing the user to easily adjust the opening angle of support plate 20 and quickly lock it into position once the adjustment is complete. This design not only enhances the user experience but also ensures the stability and safety of support plate 20 during the opening process.

[0043] Furthermore, the movable part 41 is a movable buckle.

[0044] There are many types of snap fasteners, including spring fasteners, snap fasteners, hasps, and press studs. These fasteners offer flexibility, reliability, ease of operation, and relatively low production costs. They can be opened and closed as needed, facilitating assembly, repair, and replacement. They can withstand significant tension and torque, ensuring a secure connection.

[0045] Furthermore, the second elastic band 40 is further provided with an elastic buckle 43 , which is connected to the second elastic band 40 , and the other end of the second elastic band 40 is passed through the movable part 41 and connected to the elastic buckle 43 .

[0046] In this embodiment, the elastic buckle 43 is provided to adjust the extension length of the second elastic band 40, thereby cooperating with the movable member 41 to change the opening angle of the support plate 20, thereby achieving an adjustable opening angle of the support frame of the solar foldable bag, achieving different placement tilt angles, and maintaining stability when placed at different opening angles.

[0047] Furthermore, the first elastic band 30 and the second elastic band 40 are made of nylon, polyester, silicone or thermoplastic polyurethane.

[0048] Nylon, a synthetic fiber, is renowned for its high strength, abrasion resistance, aging resistance, and excellent elasticity. In elastic band applications, nylon not only effectively withstands high levels of stretch and rebound, but also maintains stable performance over long periods of use, resisting deformation or breakage. Furthermore, nylon elastic bands are water-resistant, maintaining excellent performance even in humid environments.

[0049] Polyester, another common elastic band material, also offers excellent abrasion and wrinkle resistance. Its dense fiber structure and smooth surface allow it to rebound quickly when stretched while maintaining a low coefficient of friction. Furthermore, polyester offers high UV resistance, effectively resisting aging in direct sunlight and extending the life of the elastic band.

[0050] Silicone is soft, non-toxic and environmentally friendly. It also has good high and low temperature resistance, and can maintain stable performance whether it is cold winter or hot summer.

[0051] Thermoplastic polyurethane (TPU) is a thermoplastic elastomer that combines the elasticity of rubber with the processability of plastic, offering excellent wear resistance, oil resistance, chemical resistance, and high elasticity. In the field of elastic bands, TPU stands out for its exceptional tensile strength and resilience. TPU elastic bands can not only withstand high tensile loads but also return to their original shape in a very short time.

[0052] Furthermore, the support plate 20 further includes a rotating shaft 21 , both ends of the rotating shaft 21 are connected to the plate body 10 , and a side surface of the rotating shaft 21 is rotatably connected to the support plate 20 .

[0053] The rotating shaft 21 is a component that can rotate freely about its axis. In the application scenario of the support plate 20, the rotating shaft 21 is cleverly designed and installed at both ends of the plate body 10, and its side is tightly connected to the support plate 20 through a precise rotational connection. This design not only ensures that the rotating shaft 21 can rotate smoothly within the predetermined track, but also greatly enhances the overall flexibility and adaptability of the support plate 20.

[0054] Furthermore, the design of shaft 21 fully considers key factors such as durability and stability. Shaft 21 is typically constructed from high-strength, wear-resistant alloys to ensure optimal performance even under long-term, high-load operating conditions. Furthermore, through precise machining and strict quality control, every detail of shaft 21 is polished to perfection, ensuring smooth and accurate rotation.

[0055] Furthermore, the solar foldable bag further includes a Velcro 50 , the sub-surface of the Velcro 50 is arranged on the plate body 10 , and the main surface of the Velcro 50 is arranged on a side of the support plate 20 away from the plate body 10 .

[0056] Velcro 50, also known as snap fasteners or hook and loop fasteners, is an extremely practical fastening material. It consists of a hook surface with fine, soft fiber nap on one side and a stiff, hook-like loop surface on the other. With a simple press, the two sides quickly adhere and can be separated with a simple tear without damaging the attached items. This design is not only durable but also easy to use, making it widely used in clothing, shoes, hats, luggage, and other fields.

[0057] In the foldable solar bag, Velcro 50 is cleverly applied between the panel 10 and the support plate 20. Specifically, the sub-surface of the Velcro 50 is carefully placed on the panel 10, while the main surface is located on the side of the support plate 20 away from the panel 10. This design allows the user to easily connect the panel 10 and the support plate 20 with the Velcro 50 when using the foldable solar bag, forming a stable whole. When folding or storing, the two can be quickly separated for quick and convenient storage.

[0058] It's worth noting that the Velcro 50 design not only enhances the foldable solar panel's portability but also enhances its durability and stability. Thanks to its strong adhesive strength, the Velcro 50 ensures a tight connection between the panel 10 and the support plate 20, even in complex and changing outdoor environments, preventing loosening or detachment that could affect the solar panel's power generation efficiency. Furthermore, the reusability of the Velcro 50 significantly reduces maintenance costs for users and extends the product's lifespan.

[0059] Furthermore, two ends of the first elastic band 30 are respectively arranged close to the sub-surface of the Velcro 50 and the main surface of the Velcro 50 .

[0060] Before delving into the ingenious design of the elastic band and Velcro 50, we must first examine its fundamental structure. The elastic band, a seemingly simple yet powerful item, requires a crucial design at its ends, as they directly impact its ease of use and stability. Specifically, the ends of the elastic band are meticulously designed to approach and closely adhere to the inner and outer surfaces of the Velcro 50, respectively. This design not only demonstrates the ingenuity of the engineers but also demonstrates unparalleled convenience and efficiency in practical application.

[0061] First, let's take a look at the basic structure of Velcro 50. This everyday item consists of two main parts: a "sub-surface" (typically with tiny hook-like fibers) and a "sub-surface" (covered with a soft, fleece-like layer that tightly bonds with the sub-surface's hook-like fibers). This design allows Velcro 50 to be easily and quickly attached and detached, making it widely used in clothing, footwear, backpacks, and sports equipment.

[0062] In the design of the elastic band, the two ends are tightly connected to the sub-surface and the main surface of the Velcro 50 respectively. This design enables the elastic band to be quickly and firmly fixed to the desired position during use, greatly improving the convenience of use.

[0063] Furthermore, the support plate 20 is made of polyester fiber, polycarbonate or nylon.

[0064] Polyester fiber is known for its excellent corrosion resistance, wear resistance, and excellent insulation properties. In the application of support plate 20, polyester fiber's lightweight and high-strength properties are particularly prominent, making the support plate 20 made from it both light and strong, making it ideal for applications that need to withstand certain loads but do not require excessive weight. Furthermore, polyester fiber has excellent aging resistance and can maintain stable performance in harsh environments, further extending the service life of the support plate 20.

[0065] Polycarbonate is a thermoplastic with exceptional transparency and impact resistance. The polycarbonate support plate 20 not only offers excellent impact resistance, but can withstand significant external impact without breaking. It's also worth noting that polycarbonate also offers excellent processability, allowing it to be formed into various complex shapes through various molding processes, such as injection molding and extrusion, meeting the personalized needs of various industries.

[0066] Nylon, a synthetic polymer material, holds a special place in the support plate 20 market due to its excellent wear resistance, oil resistance, and self-lubrication. Nylon's high wear resistance ensures low wear rates for these components even during extended operation, thereby extending the overall service life of the equipment. Nylon also exhibits excellent heat and chemical resistance, enabling stable operation in a variety of harsh environments.

[0067] Furthermore, the width of the support plate 20 is greater than the width of the first elastic band 30 .

[0068] In this embodiment, the width of the support plate 20 is greater than the width of the first elastic band 30. When the support plate 20 is stored, it can cover the first elastic band 30 to prevent the first elastic band 30 from being exposed, thereby protecting the first elastic band 30 and the second elastic band 40 from being affected by the external environment when the support plate 20 is in the stored state.

[0069] Furthermore, a handle 11 is provided on the top of the board body 10 .

[0070] The handle 11 is located at the top of the plate 10, which is convenient for users to lift it easily without any effort. Whether it is moving furniture for cleaning or adjusting the placement according to space requirements, it can be easily handled.

[0071] The handle 11 is typically made of metal, solid wood, or environmentally friendly plastic. These materials are not only durable but also offer user-friendly designs tailored to the user's grip. For example, a metal handle 11 might have a frosted finish for increased grip comfort, while a solid wood handle 11 might mimic the texture and color of natural wood, creating a warm and natural feel. The handle 11 also comes in a variety of shapes, ranging from rounded and smooth to sleek and flowing, each offering its own unique characteristics.

[0072] To further enhance the practicality of handle 11, some designers incorporate anti-slip features. These features typically utilize soft materials such as rubber and silicone as the anti-slip layer, effectively preventing accidents caused by slipping during handling. Furthermore, the anti-slip design reduces the stress on the hand caused by prolonged gripping of handle 11, making furniture handling more comfortable and effortless.

[0073] It can be understood that the above embodiments only express the preferred implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
