[0033] Please refer to Figure 1 , the backpack 100 of the embodiment of the present utility model includes a main body portion 10, a photovoltaic module 20, a shoulder strap 30, a handle strap 40, a light-emitting structure 50 and a reflective structure 60. The photovoltaic module 20 is disposed on the outer surface 11 of the main body portion 10; the shoulder strap 30 is connected to the main body portion 10; the handle strap 40 is connected to the shoulder strap 30 or the main body portion 10; the light-emitting structure 50 is disposed on the handle strap 40; the reflective structure 60 is located on one side of the photovoltaic module 20, and the reflective structure 60 is disposed on the main body portion 10.

[0034] In the backpack 100 of the embodiment of the present utility model, the light-emitting structure 50 is disposed on the handle strap 40 of the backpack 100, which can provide an additional light source in a night or low-light environment, improve the visibility of the backpack 100 and its user, and thus reduce the safety risk. Moreover, the reflective structure 60 disposed on the main body portion 10 can further enhance the visibility of the backpack 100. Since the visibility of the backpack 100 is enhanced in a night or dim environment, passing pedestrians or vehicles can more easily identify the position of the backpack 100 and its user, thereby reducing the occurrence of accidental collisions or accidents. In addition, in an emergency, both the light-emitting structure 50 and the reflective structure 60 can be used as signal indicators to help rescue personnel quickly locate the position of the backpack 100 and its user.

[0035] The photovoltaic module 20 on the outer surface 11 of the main body 10 can convert solar energy into electrical energy, enabling the backpack 100 to achieve self - sufficiency in energy and provide electrical energy for other devices. Moreover, since the light - emitting structure 50 is provided on the carrying strap 40, the light - emitting structure 50 not only has higher visibility but also does not occupy the space on the main body 10, which provides more space for the photovoltaic module 20. Thus, it is beneficial to set a larger - area photovoltaic module 20 on the main body 10, thereby increasing the capacity of the photovoltaic module 20.

[0036] Specifically, the main body 10 is the main contour - shaped part of the backpack 100 for loading items. The main body 10 can be made of materials such as nylon, canvas, or leather. The main body 10 can include multiple pockets and compartments and can form multiple chambers or cubicles for loading different types of items.

[0037] The photovoltaic module 20 is a component for converting solar energy into electrical energy. The photovoltaic module 20 can include monocrystalline silicon, polycrystalline silicon, or thin - film solar cells, and includes a fixing part. Among them, the battery part of the photovoltaic module 20 is used for photoelectric conversion, and the fixing part of the photovoltaic module 20 is used for connecting with the outer surface 11 of the main body 10. The photovoltaic module 20 can be set in any area of the outer surface 11 of the main body 10. In order to enable the photovoltaic module 20 to have a better illumination angle, the illumination component can be set on the side of the main body 10 facing the sun, or in other words, on the side of the main body 10 away from the user's back when the backpack 100 is being carried. The photovoltaic module 20 can be flexible to adapt to the shape of the main body 10.

[0038] The photovoltaic module 20 can be set on the outer surface 11 of the main body 10 by means of adhesion, stitching, or using zippers or Velcro fasteners. For example, the fixing part of the photovoltaic module 20 can be stitched to the outer surface 11 of the main body 10. The battery part of the photovoltaic module 20 can be adhered to the outer surface 11 of the main body 10.

[0039] The shoulder straps 30 can be used to fix the backpack 100 on the user's shoulders. The shoulder straps 30 and the main body 10 can be connected by means of stitching, adhesion, etc. The shoulder straps 30 can be respectively connected to both ends of the length direction L of the main body 10. For example, each shoulder strap 30 can include opposite ends, and the two ends of the shoulder strap 30 are respectively connected to both ends of the length direction L of the main body 10. The number of shoulder straps 30 can be one or more, such as two, three, four, or even more.

[0040] The carrying strap 40 is used for the user to carry the backpack 100 by hand. Along the length direction of the backpack, the carrying strap 40 can be located at the upper part of the backpack 100 and can be set near the connection of the shoulder strap 30 and the main body 10. Among them, the length direction of the backpack 100 can be the same as the length direction L of the main body 10.

[0041] In one embodiment, the carrying strap 40 is connected to the main body portion 10. In this way, when the user extracts the backpack 100, the carrying strap 40 directly connected to the main body portion 10 can be more conveniently grasped and force can be applied. In addition, since the carrying strap 40 is directly connected to the main body portion 10, when the carrying strap 40 is lifted, the acting force exerted by the main body portion 10 on the shoulder strap 30 is smaller, thereby making the structure between the shoulder strap 30 and the main body portion 10 more stable.

[0042] Please refer to Figure 1 , in one embodiment, the carrying strap 40 is connected to the shoulder strap 30. In this way, since the carrying strap 40 is connected to the shoulder strap 30, this can disperse the acting force generated by the main body portion 10 on the carrying strap 40.

[0043] Please refer to Figure 1 , in one embodiment, the number of shoulder straps 30 can be two, and the carrying strap 40 is connected to the two shoulder straps 30. When the carrying strap 40 is lifted, the acting force exerted by the main body portion 10 is transmitted to the carrying strap 40 through the two shoulder straps 30, and the force received by the carrying strap 40 is smaller, thereby being able to extend the service life of the carrying strap 40. For the case where the number of shoulder straps 30 is multiple, the connection manner between the carrying strap 40 and the shoulder straps 30 can be the same or different. For example, the carrying strap 40 and one of the shoulder straps 30 can be connected by sewing, and the carrying strap 40 and the other shoulder strap 30 can be connected by adhesion.

[0044] The connection manner between the carrying strap 40 and the shoulder strap 30, or between the carrying strap 40 and the main body portion 10 can be sewing, adhesion, etc.

[0045] The light-emitting structure 50 can be provided on the carrying strap 40 by sewing, adhesion, coating, etc. The light-emitting structure 50 can be an LED (Light Emitting Diode) lamp or a cloth strip made of light-emitting fiber, light-emitting paint, etc. Among them, the light-emitting fiber and the light-emitting paint can be any existing fiber or paint that can emit light, and can be obtained by purchasing in the market or manufactured according to the existing process.

[0046] For example, the light-emitting structure 50 can be a fluorescent cloth strip, and the fluorescent cloth strip can be provided on the carrying strap 40 by weaving or sewing. Compared with methods such as LED lamps, the fluorescent cloth strip does not require a power source. The fluorescent cloth strip can be charged by absorbing daily light and emit light naturally in the dark, which is an energy-saving light-emitting method.

[0047] For another example, the light-emitting structure 50 can be an LED lamp, and the backpack 100 further includes an electric wire. The LED lamp is electrically connected to the photovoltaic module 20 through the electric wire, and the photovoltaic module 20 can provide electrical energy for the LED lamp. The LED lamp can provide a larger range of light source coverage, thereby being able to improve the visibility of the backpack 100.

[0048] The reflective structure 60 can be located on one side of the photovoltaic module 20 along the length direction L of the main body 10, or on one side of the photovoltaic module 20 along the width direction W of the main body 10. The reflective structure 60 can be arranged on the main body 10 by means of stitching, gluing, coating, etc.

[0049] The reflective structure 60 can be a reflective cloth, a reflective film, a reflective coating, etc. Among them, the reflective cloth, the reflective film, and the reflective coating can all be obtained by purchasing in the market or manufactured according to existing processes. For example, the reflective structure 60 can be a reflective cloth strip, and the reflective cloth strip can reflect the surrounding light, so as to provide functions such as warning. The reflective cloth strip can be arranged on the main body 10 by means of stitching, weaving, etc.

[0050] Please refer to Figure 1 , in some embodiments, the main body 10 includes a first part 12 and a second part 13 protruding from one side of the first part 12, and the photovoltaic module 20 is arranged on the second part 13.

[0051] In this way, by arranging the photovoltaic module 20 on the second part 13, this can optimize the weight distribution of the backpack 100 and improve the comfort and balance of the backpack 100. In addition, the second part 13 protruding from one side of the first part 12 is more suitable for receiving sunlight, thereby improving the energy efficiency of the photovoltaic module 20 and increasing the conversion and storage of electric energy.

[0052] Specifically, the first part 12 can be used to accommodate items. The second part 13 can be used to attach or fix other components, such as the photovoltaic module 20. The second part 13 can protrude from one side of the first part 12 along the thickness direction of the main body 10. The first part 12 and the second part 13 can be connected by means of stitching, gluing, etc.

[0053] In some embodiments, the color of the first part 12 is a first color, the color of the second part 13 is a second color different from the first color, and the second color is the same as the color of the photovoltaic module 20.

[0054] In this way, the differential design of the colors of the first part 12 and the second part 13 can increase the aesthetic degree of the backpack 100. The color of the photovoltaic module 20 is the same as the color of the second part 13 of the backpack 100, which can make the photovoltaic module 20 more visually concealed and reduce its impact on the overall aesthetics of the backpack 100.

[0055] Specifically, the first color can be any color and can be selected according to the user's preference or market trend. The second color can be a color different from the first color. For example, the first color is gray and the second color is black. The second color being the same as the color of the photovoltaic module 20 means that the two colors belong to the same color system, such as both being in the black color system or both being in the gray color system, etc., without restricting that both have the same hue, saturation, brightness or lightness, etc. For example, light gray and dark gray both belong to the gray color system.

[0056] Among them, the color can be detected by means such as a color difference meter, color card comparison, etc.

[0057] In some embodiments, the photovoltaic module 20 is stitched to the second part 13. In this way, the photovoltaic module 20 is stitched to the second part 13 of the backpack 100, which can ensure the stability of the photovoltaic module 20 during use and reduce displacement or detachment caused by activities or movements.

[0058] Specifically, the stitching method can be manual stitching or machine stitching, and different stitching stitches can be used, such as overlock stitch, backstitch, etc. The stitching thread can be nylon, polyester or other fibers with higher strength, and the color of the thread can match the second part 13 or the photovoltaic module 20. The stitching between the photovoltaic module 20 and the second part 13 can be full-area stitching or only stitching at the edge of the photovoltaic module 20. For example, a layer of fabric can be covered on the side of the photovoltaic module 20 facing the second part 13, and the fabric is stitched to the second part 13. For another example, the fixed part of the photovoltaic module 20 is stitched to the second part 13, which can reduce the adverse effect of the stitching thread on the battery part of the photovoltaic module 20.

[0059] Please refer to Figure 1 , in some embodiments, the shape of the reflective structure 60 is elongated, and the reflective structure 60 extends along the width direction W of the main body portion 10.

[0060] In this way, the reflective structure 60 extending along the width direction of the main body portion 10 can better adapt to light at different angles and ensure that light irradiated from multiple directions can be effectively reflected. No matter in what posture the backpack 100 is carried, the elongated reflective structure 60 can maintain its visibility and is not affected by the carrying method.

[0061] In addition, the elongated reflective structure 60 can be recognized at a farther distance, which helps to improve the recognition ability of the carrier of the backpack 100 by passing vehicles or pedestrians and reduces the risk of accidents at night or under poor visibility conditions.

[0062] In addition, the reflective structure 60 extending in the width direction of the main body portion 10 is conducive to the layout of the photovoltaic module 20, thereby facilitating the setting of a larger area of the photovoltaic module 20 on the main body portion 10, thus increasing the capacity of the photovoltaic module 20.

[0063] Specifically, the long strip shape can be linear, wavy, arc-shaped or any other streamline variant. The reflective structure 60 can be a continuously extending structure or a discontinuously extending structure. For example, the reflective structure 60 can include a first reflective portion, a second reflective portion and a third reflective portion that are sequentially extended along the width direction W of the main body portion 10, and the reflective portions are spaced from each other.

[0064] Extending along the width direction W of the main body portion 10 means that the opposite ends of the reflective structure 60 are arranged at intervals along the width direction W of the main body portion 10. The shape of the reflective structure 60 can be a straight line extending along the width direction W of the main body portion 10 or a wavy line extending along the width direction W of the main body portion 10.

[0065] Please refer to Figure 1 , in some embodiments, the main body portion 10 includes a first portion 12 and a second portion 13 protruding from one side of the first portion 12, and the reflective structure 60 is disposed on the second portion 13 and extends to the connection portion 14 between the first portion 12 and the second portion 13.

[0066] In this way, the reflective structure 60 extends to the connection portion 14 between the first portion 12 and the second portion 13, expanding the reflective coverage range, thereby improving the visibility of the backpack 100 in a larger range.

[0067] Please refer to Figure 2 , in some embodiments, the shape of the reflective structure 60 is a continuous ring shape, and the reflective structure 60 extends along the circumferential direction of the main body portion 10.

[0068] In this way, the ring-shaped reflective structure 60 can not only improve the visibility of the backpack 100 when the backpack 100 is carried, but also improve the visibility of the backpack 100 when the backpack 100 is not carried. For example, in a night or a dim light environment, if the backpack 100 is lost, no matter in what way the backpack 100 faces the ground, the reflective structure 60 can provide a reflective function.

[0069] Specifically, the ring shape can be a circular ring shape, an elliptical ring shape, etc.

[0070] In some embodiments, the shape of the reflective structure 60 is a text shape.

[0071] Thus, in the night or low lighting conditions, the reflective structure 60 in the shape of characters can provide clear warnings to help others identify the position of the carrier of the backpack 100. At the same time, the reflective structure 60 in the shape of characters can improve the aesthetic appearance of the backpack 100, thereby enhancing the user experience.

[0072] Specifically, the characters can be letters, numbers or symbols in any language. For example, the shape of the characters can be "Attention", "Safety", "!", etc.

[0073] Please refer to Figure 2 , in one embodiment, the number of the light-emitting structures 50 is one, and the light-emitting structure 50 extends along the extending direction of the carrying strap 40. Thus, the light-emitting structure 50 occupies a relatively large area on the carrying strap 40, thereby improving the visibility of the backpack 100.

[0074] In one embodiment, the entire area of the carrying strap 40 is provided with the light-emitting structures 50. Thus, the entire area of the carrying strap 40 can be used as the light-emitting area of the light-emitting structures 50, effectively improving the visibility of the backpack 100.

[0075] Please refer to Figure 1 and Figure 2 , in some embodiments, the number of the light-emitting structures 50 is plural, and the light-emitting structures 50 are arranged at intervals along the extending direction of the carrying strap 40.

[0076] Thus, the arrangement of the plural light-emitting structures 50 along the carrying strap 40 can provide a wider light source coverage and improve the visibility of the backpack 100. The plural light-emitting structures 50 can ensure that even if some of the light-emitting structures 50 fail, the backpack 100 still maintains a certain visibility, increasing the practicality.

[0077] Specifically, the light-emitting structures 50 are arranged at intervals along the extending direction of the carrying strap 40 to form a series of light-emitting points. The number of the light-emitting structures 50 can be two, three, four or even more, and the distance between adjacent light-emitting structures 50 can be the same or different. The shape of the light-emitting structures 50 can be strip-shaped or annular. The sizes and shapes of the plural light-emitting structures 50 can be the same or different. Among them, the extending direction of the carrying strap 40 can be the same as the width direction W of the main body portion 10 or different from the width direction W of the main body portion 10.

[0078] Please refer to Figure 1 and Figure 2 , in one embodiment, the number of the light-emitting structures 50 can be two, and the two light-emitting structures 50 are arranged on the carrying strap 40 at intervals. The two light-emitting structures 50 are both annular and extend along the circumferential direction of the carrying strap 40.

[0079] Please refer to Figure 1 and Figure 2, in some embodiments, the number of photovoltaic modules 20 is multiple, and the multiple photovoltaic modules 20 are spaced apart from each other.

[0080] In this way, the multiple photovoltaic modules 20 can increase the surface area of the backpack 100 receiving sunlight, thereby increasing the total amount of energy collection. The multiple photovoltaic modules 20 can ensure that even if some of the photovoltaic modules 20 fail, the backpack 100 still maintains a certain energy supply capacity, increasing its practicality.

[0081] The intervals between the photovoltaic modules 20 can improve heat dissipation because these intervals provide space for air circulation, which helps reduce the probability of overheating of the photovoltaic modules 20, thereby extending the service life of the photovoltaic modules 20.

[0082] Specifically, the number of photovoltaic modules 20 can be two, three, four or more. The multiple photovoltaic modules 20 can be connected in series or in parallel. The layout of the multiple photovoltaic modules 20 can be symmetrical or asymmetrical. The sizes and shapes of the multiple photovoltaic modules 20 can be the same or different.

[0083] Please refer to Figure 1 and Figure 2 , in one embodiment, the number of photovoltaic modules 20 is four. The four photovoltaic modules 20 have the same shape and size, the four photovoltaic modules 20 are connected in series with each other, and the four photovoltaic modules 20 are arranged in a rectangular array.

[0084] In the description of this specification, the description with reference to terms such as "one embodiment", "certain embodiments", "schematic embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in connection with the said embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0085] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand 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 claims and their equivalents.
