Description

Technical Field

[0001] This invention relates to the field of photovoltaic module application technology, and in particular to a photovoltaic handbag. Background Technology

[0002] A photovoltaic handbag is a portable electronic device that combines a solar panel with a handbag. It absorbs light energy through the solar panel, converts it into electrical energy, and then stores it in a storage battery after being regulated by a controller. When it is necessary to charge electronic devices, the electrical energy in the storage battery can be transferred to the device through output ports such as the USB interface in the bag to provide power. Therefore, the photovoltaic handbag charges various electronic devices using solar energy, which is both practical and environmentally friendly.

[0003] In the prior art, Chinese patents such as CN221616430U, CN213604873U, and CN120052654A disclose a variety of photovoltaic handbags. Although these photovoltaic handbags can absorb solar energy through solar cells and convert it into electrical energy to power other electronic devices, the photovoltaic panels are usually fixed on the surface of the handbag, resulting in a limited light-receiving area. This leads to limited energy conversion efficiency of the internal energy storage battery, making it difficult to achieve continuous operation of electrical products. Moreover, the fixed installation of the solar panels and energy storage batteries in these handbags makes it difficult to clean them. During the cleaning process, water can easily enter and damage the solar panels and energy storage batteries, affecting the continuous use of the photovoltaic handbag.

[0004] Therefore, it is necessary to improve the existing photovoltaic handbag technology. Summary of the Invention

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] like Figures 1-11 As shown, a photovoltaic handbag of the present invention includes: The package 1 has an open top and an outer surface including opposing main side surfaces 11. At least one of the main side surfaces 11 has a mounting through hole 111. The length and width directions of the mounting through hole 111 are consistent with the length and width directions of the main side surface 11, respectively. A mounting frame 2 is fixedly connected to its inner wall inside the mounting through hole 111. The top cover 3 and the fastener 4 are fixedly connected to one of the main side surfaces 11 on one side, and the other side is detachably connected to the other main side surface 11 through the fastener 4, so as to close or seal the opening of the bag body 1. The photovoltaic module 5 includes at least two solar cells 51 that are rotatably connected in sequence. The rotation axes of two adjacent solar cells 51 are parallel. All solar cells 51 are bifacial photovoltaic cells 51. One of them is detachably connected to the mounting frame 2. The photovoltaic module 5 has a folded-down form and an unfolded form. In the folded-down form, two adjacent solar cells 51 are arranged opposite each other on the inner side of the mounting frame 2. In the unfolded form, the solar cell 51 detachably connected to the mounting frame 2 is located on the inner side of the mounting frame 2, and the remaining solar cells 51 are located on the outer side of the mounting frame 2 and the package 1. Locking component 6 is used to lock the folded photovoltaic module 5 to the inside of the mounting frame 2; The storage battery 7 is detachably installed inside the housing 1 and electrically connected to the photovoltaic module 5. The storage battery 7 is provided with a power connector 71.

[0020] Compared with the prior art, the photovoltaic handbag of the present invention has the following advantages: First, the solar cell 51 in the photovoltaic module 5 is a bifacial photovoltaic cell 51, and both sides of the solar cell 51 can be used to receive light to generate electricity, thereby increasing the power generation. Secondly, the photovoltaic module 5 is composed of multiple solar cells 51 connected by rotation, and has both a folded and unfolded form. When used in a handbag, the photovoltaic module 5 adopts the folded form, such as... Figure 1 and Figure 2 As shown, the photovoltaic module 5 is locked and fixed within the mounting frame 2 by the locking component 6; when the handbag is not in use, the photovoltaic module 5 can be switched to the unfolded form, as shown. Figures 3-6 As shown, in this configuration, the originally folded battery cell 51 unfolds, thereby significantly increasing the light absorption area, increasing power generation, and thus improving the energy storage efficiency of the battery 7 inside the housing 1, meeting the power supply requirements of various electronic products. Finally, the photovoltaic module 5 is detachably connected to the mounting frame 2, and the battery 7 is removably and washably housed inside the case 1. With the above structure, it is convenient to remove the photovoltaic module 5 from the mounting frame 2 and take out the battery 7 from the case 1 when the case 1 needs to be cleaned, so as to avoid the photovoltaic module 5 and the battery 7 getting wet and damaged when the case 1 is cleaned. After the case 1 is cleaned, the battery 7 is put back into the case 1 and the photovoltaic module 5 is installed in the mounting frame 2.

[0021] The mounting frame 2 of the present invention is preferably made of lightweight aluminum alloy or reinforced plastic material, so as to ensure the lightweight nature of the mounting frame 2 while meeting the structural strength requirements, thereby reducing the burden on the user.

[0022] Specifically, the package body 1 of the present invention is elongated, and its outer surface includes a main bottom surface 13, two opposing main side surfaces 11, and two opposing main end surfaces 12. The two main end surfaces 12 are arranged opposite each other along the length direction of the package body 1, and the two main side surfaces 11 are arranged opposite each other along the width direction of the package body 1. The bottom of the two main end surfaces 12 and the two main side surfaces 11 are smoothly connected to the four sides of the main bottom surface 13. The two main end surfaces 12 and the two main side surfaces 11 are connected end to end, thereby making the top of the package body 1 open to form a package opening.

[0023] Both main sides 11 are integrally connected to the upper part of a U-shaped handle 16, and the two ends of the handle 16 are respectively connected to the corresponding main side 11, which facilitates the carrying of the photovoltaic handbag of the present invention.

[0024] The top cover 3 is made of the same material as the bag body 1 and runs along the same length as the top cover 3. One side of the top cover 3 is integrally connected to the main side 11 away from the photovoltaic module 5. Three pairs of fasteners 4 are provided, distributed along the length of the bag body 1. The fasteners 4 include a male buckle 41 fixed to the main side 11 of the bag body 1 away from the photovoltaic module 5 and a female buckle 42 fixed to the top cover 3. The male buckle 41 engages with the female buckle 42 to form a male-female buckle, securing the top cover 3 away from the side integrally connected to the main side 11 of the bag body 1, thus closing and covering the opening of the bag body 1. When the user needs to take or put away the bag, the male buckle 41 and the female buckle 42 are separated, and the top cover 3 is opened.

[0025] A further improvement is that each of the two main side surfaces 11 is provided with a mounting through hole 111, and a mounting frame 2 is fixedly connected to the circumferential inner wall of the mounting through hole 111. A photovoltaic module 5 is installed in one of the mounting frames 2, and a light-transmitting sheet 8 is detachably installed in the other mounting frame 2. The circumferential outer edge of the light-transmitting sheet 8 is sealed to the circumferential inner wall of the mounting frame 2. Two locking components 6 are provided, which are used to set the light-transmitting sheet 8 and the folded photovoltaic module 5 in the mounting frame 2 respectively.

[0026] With the above design, the light-transmitting sheet 8 installed in the mounting frame 2 on the other main side 11 allows external light from the other side to pass through the light-transmitting sheet 8 and enter the interior of the housing 1, illuminating the side of the solar cell 51 closest to the interior cavity of the housing 1. This increases the amount of light received by the side of the solar cell 51 closest to the interior cavity of the housing 1 (regardless of whether the photovoltaic module 5 is in a folded or unfolded state). Therefore, with the above structure, the amount of light absorbed can be significantly increased, the power generation efficiency can be improved, and the energy storage efficiency of the battery 7 can be improved to meet the power supply needs. Moreover, the light-transmitting sheet 8 can be detachably installed in its corresponding mounting frame 2, which facilitates the individual disassembly, cleaning and maintenance of the light-transmitting sheet 8 to ensure its light transmission efficiency and prevent the amount of light entering the housing 1 from being affected by wear of the light-transmitting sheet 8.

[0027] A further improvement is that the light-transmitting sheet 8 is a one-way light-transmitting sheet 8, and the light transmission direction is from the outside of the package 1 through the plane where the main side 11 is located to the inside of the package 1.

[0028] With the above design, light inside the bag 1 can be prevented from being transmitted to the outside through the light-transmitting sheet 8. On the one hand, it ensures that there is enough light inside the bag 1 to illuminate the back of the battery cell 51 to ensure the power generation efficiency of the battery cell 51. On the other hand, it can prevent other people from observing the items stored inside the user's bag 1, thereby protecting the user's privacy information.

[0029] Preferably, the light-transmitting sheet 8 uses a PC board composite layer and a one-way transparent film stacked on the side of the PC board composite layer facing away from the inner cavity of the package 1 to improve light transmittance and meet the needs of outdoor power generation. In addition, the PC board composite layer is scratch-resistant, impact-resistant, and relatively lightweight.

[0030] To further ensure the power generation efficiency of the photovoltaic module 5 in this invention, the two ends of the mounting frames 2 on both sides of the package 1 are respectively adjacent to the two main end faces 12, and one side is adjacent to the main bottom face 13. In this way, it is ensured that the solar cells 51 in the photovoltaic module 5 have sufficient power generation area and the light-transmitting sheet 8 has a large light-transmitting surface and light transmission amount.

[0031] A further improvement is that the locking assembly 6 includes a locking arm 61 that rotates on the mounting frame 2 with its rotation axis perpendicular to the opening of the mounting frame 2. The movement path of the locking arm 61 includes a locking position and a disassembly position. In the locking position, the locking arm 61 intersects with the opening of the mounting frame 2. In the disassembly position, the locking arm 61 is separated from the opening of the mounting frame 2. A central shaft 21 is integrally connected to the side of the mounting frame 2 away from the inner cavity of the package 1. An elastic damping sleeve 62 is sandwiched between the locking arm 61 and the central shaft 21. An elastic pressure plate 63 is provided on the side of the locking arm 61 away from the central shaft 21 and close to the inner cavity of the package 1. An inner convex frame 22 is provided on the circumferential inner wall of the mounting frame 2. In the two locking assemblies 6, the locking arm 61 in the locking position cooperates with the inner convex frame 22 to clamp the light-transmitting sheet 8 and the folded photovoltaic module 5.

[0032] Specifically, in this invention, the mounting frame 2 is a rectangular frame, and the central shaft 21 is integrally formed. At the four corners of the side of the outer mounting frame 2 facing away from the package body 1, the locking arm 61 is sleeved on the outside of the central shaft 21. By rotating the locking arm 61, the position of the locking arm 61 can be adjusted, so that the locking arm 61 can switch between the locking position and the disassembly position. In the disassembly position, the photovoltaic module 5 and the light-transmitting sheet 8 can be taken out from the frame opening of the mounting frame 2. In the locking position, the locking arm 61 cooperates with the inner convex frame 22 to clamp the photovoltaic module 5 and the light-transmitting sheet 8, thereby fixing the position of the photovoltaic module 5 and the light-transmitting sheet 8. The damping sleeve 62 is a silicone sleeve that is sealed between the central shaft 21 and the locking arm 61. The damping sleeve 62 can limit the rotation of the locking arm 61 and prevent the locking arm 61 from rotating without being affected by external force, thus facilitating the fixing of the position of the locking arm 61. The pressure plate 63 is a rubber plate with elasticity, thus preventing the rigid locking arm 61 from rigidly contacting the light-transmitting sheet 8 or photovoltaic module 5. The pressure plate 63 provides cushioning while locking, preventing damage to the light-transmitting sheet 8 and photovoltaic module 5.

[0033] A further improvement is that a suction cup 24 is provided on the side of the inner convex frame 22 of one of the mounting frames 2 that faces away from the inner cavity of the package body 1, and a protective frame 52 is provided on the circumferential outer edge of the battery cell 51. The protective frame 52 is detachably connected to the mounting frame 2 through the suction cup 24.

[0034] Specifically, in the photovoltaic module 5, the surface of the cell 51 is covered with a transparent and wear-resistant polycarbonate protective film to prevent the cell 51 from being scratched and damaged on both sides. A protective frame 52 is fixed to the outer circumferential edge of the cell 51. The two ends of two adjacent protective frames 52 are hinged to each other by a connecting rod 54 to realize the rotational connection of adjacent cells 51.

[0035] In one of the two mounting frames 2, the inner convex frame 22, facing away from the inner cavity of the package body 1, has multiple suction cups 24 distributed along the circumference of the mounting frame 2. The suction cups 24 are used to connect with the protective frame 52. In this way, the mounting frame 2 and the battery cell 51 can be detachably and fixedly connected through the suction cups 24. After the suction cups 24 are connected to the protective frame 52, the thickness and strength of the protective frame 52 are greater than the thickness and strength of the battery cell 51, which avoids the battery cell 51 being damaged by pressure during disassembly.

[0036] The other mounting frame 2 corresponds to the light-transmitting sheet 8. The side of the light-transmitting sheet 8 facing away from the package body 1 is fixed with a buffer pad 81. The buffer pad 81 is a rectangular rubber frame. With this structure, when the light-transmitting sheet 8 is locked, both sides are connected to the elastic buffer pad 81 and the elastic pressure plate 63 respectively, avoiding damage to both sides of the light-transmitting sheet 8 due to rigid compression contact.

[0037] A further improvement is that both ends of the outer periphery of the mounting frame 2 are provided with an outer protruding frame 23. The outer protruding frame 23 is provided with a number of first through holes 231 distributed along its own periphery. The side wall of the package 1 where the main side 11 is located is sandwiched between the outer protruding frames 23 and has a second through hole 112 corresponding to the first through hole 231. A fastener 25 formed by curable material is provided between the first through hole 231 and the second through hole 112. The side wall where the main side 11 is located is sandwiched between the outer protruding frames 23.

[0038] With the above structure, the fastener 25, which is formed by curing a curable material, is filled between the first through hole 231 and the second through hole 112, thereby fixing the outer convex frame 23 to the side wall where the main side 11 is located, and preventing the mounting frame 2 from detaching from the package body 1 during the cleaning process.

[0039] A further improvement is that the outer diameter of the first through hole 231 is larger than the outer diameter of the second through hole 112.

[0040] With the above design, the fastener 25, which is formed by curing the curable material, has a structure that is thick at both ends and thin in the middle. This prevents the fastener 25 from detaching from the first through hole 231 and the second through hole 112, further strengthening the connection structure between the mounting frame 2 and the package 1 and preventing them from detaching from each other.

[0041] It should be noted that the curable material used for the fastener 25 in this invention has multiple options. For example, UV-curable acrylic adhesive has a fast curing speed, high bonding strength, low volume shrinkage after curing, and strong weather resistance, making it particularly suitable for the connection between the mounting frame 2 made of metal or plastic and the package 1 made of nylon or Oxford cloth. Alternatively, the curable material can be a two-component epoxy adhesive, which has a wide bonding range and is suitable for bonding between plastics, fabrics, and metals. After curing, it has high hardness, high shear strength, and excellent water and aging resistance, making it suitable for the connection between the package 1 and the mounting frame 2. Alternatively, the curable material can be a hot melt adhesive, which has good fluidity after heating, can quickly fill the first through hole 231 and the second through hole 112, and can be easily and quickly cured. When the package 1 is made of fabric and the mounting frame 2 is made of plastic, a fast and firm connection between the two can be achieved.

[0042] Further improvements include, for example Figures 7-10As shown, a screw 14 is provided on the inner bottom wall of the package 1. In the photovoltaic module 5, the battery cell 51, which is detachably connected to the corresponding mounting frame 2, is connected to a power supply board 53 via a wire 55. The power supply board 53 is sleeved on the screw 14 and is provided with a power supply connector 531 that is electrically connected to the battery cell 51 via the wire 55. The bottom of the battery 7 is provided with a power supply interface 73 that is compatible with the power supply connector 531. The battery 7 is fixedly connected to a clamp 72 sleeved on the screw 14. The screw 14 is threaded with a screw sleeve 15 to lock the clamp 72 and the power supply board 53 to the bottom of the package 1.

[0043] With the above structure, by sequentially sleeved the power supply board 53 and the clamping plate 72 from bottom to top onto the screw 14, the power supply connector 531 on the power supply board 53 is precisely inserted into the power supply interface 73. This allows the electrical energy generated by the photovoltaic module 5 to be transmitted to the battery 7 through the wire 55 and the power supply connector 531. Furthermore, the power supply connector 531 and the power supply interface 73 of the battery 7 are located at the bottom and are fixed in position, preventing the power supply connector 531 from detaching due to collisions with items placed inside the case 1. This ensures a firm connection between the power supply connector 531 and the power supply interface 73. By rotating the screw sleeve 15 downwards, the clamping plate 72 and the power supply board 53 are locked and fixed from top to bottom, further ensuring the fixed position of the battery 7 and preventing the battery 7 from shaking inside the case 1.

[0044] When cleaning the housing 1 is required, rotate the screw sleeve 15 in the opposite direction to disengage it from the screw rod 14. Then, remove the battery 7, which is fixedly connected to the clamp plate 72, from the housing 1. Remove the power supply board 53 from the screw rod 14. Rotate each locking arm 61 on the mounting frame 2 to the disassembly position. Remove the protective frame 52 from the suction cup 24. Then, remove the power supply board 53 from the housing 1 and the battery cell 51 from the mounting frame 2. This completes the disassembly of the photovoltaic module 5 and facilitates cleaning of the housing 1.

[0045] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
