These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, a solar-powered electric canopy is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a solar-powered electric canopy according to an embodiment of the present invention includes a protective shell 1 and a solar panel 13. The protective shell 1 has two sets, and a winding drum 12 is installed inside each set. One end of the winding drum 12 passes through one side of the protective shell 1 and is connected to a motor 2. A fabric body 4 is wound and connected to the surface of the winding drum 12. Multiple sets of fabric bodies 4 are provided. A mating groove 5 is formed on one side of each set of fabric bodies 4. A fastening groove 6 is formed at the top of the mating groove 5. A connecting metal strip 18 is sewn at the bottom of the mating groove 5. A connecting metal strip 18 is sewn on the other side of the fabric body 4. There is a connecting strip 8, and the inside of the connecting strip 8 is wrapped with a filler metal strip 19. Several sets of threaded holes 20 are opened on the surface of the filler metal strip 19 and the surface of the connecting metal strip 18. The connecting groove 5 and the connecting strip 8 are connected by fastening screws 7. A shielding strip 17 is pasted on the surface of the fastening groove 6. The shielding strip 17 is set to shield the fastening groove 6 to avoid the exposure of the structure. At the same time, the connection between the shielding strip 17 and the fastening groove 6 can be adjusted by personnel according to needs, such as sewing or pasting. The specific method can be adjusted according to personnel needs.

[0028] In one embodiment, a solar panel 13 is provided on one side of the protective shell 1. The solar panel 13 is electrically connected to the control box 15 via wires. The control box 15 is electrically connected to the battery 14 via wires. Both the control box 15 and the battery 14 are electrically connected to the motor 2 via wires. The control box 15 contains an inverter and a controller. The solar panel 13, the inverter, and the controller are all common devices, and both are of various types with mature application technologies. Therefore, personnel can select them according to their needs and implement them through programming.

[0029] In one embodiment, a slot is provided on one side of the protective shell 1 for the fabric body 4 to enter and exit, and a rotating shaft 9 is symmetrically connected to both sides of the slot. Several sets of limiting wheels 10 are evenly installed on the surface of the rotating shaft 9. The limiting wheels 10 are in contact with the surface of the fabric body 4. The limiting wheels 10 are provided to assist the fabric body 4 in moving and to limit the position of the fabric body 4 to prevent it from being misaligned.

[0030] In one embodiment, the protective shell 1 has an installation cavity 11 for mounting the winding drum 12.

[0031] In one embodiment, a sealing cover 16 is rotatably connected to one side of the top of the mounting cavity 11. The sealing cover 16 is provided to seal the mounting cavity 11. By opening the sealing cover 16, it is convenient for personnel to inspect and maintain components such as the winding drum 12.

[0032] In one embodiment, magnetic strips 3 are installed at both ends of one side surface of the mating strip 8 and at both ends of one side surface inside the mating groove 5. The magnetic strips 3 are provided to improve the connection stability of the two through magnetic adsorption.

[0033] In one embodiment, the size of the mating strip 8 is larger than the size of the mating groove 5. The larger size of the mating strip 8 compared to the mating groove 5 is designed to ensure that the connection stability can be improved by compression when the two are mated. Since both the mating strip 8 and the mating groove 5 are made of the same material as the main body of the fabric 4, the mating strip 8 only needs to be compressed to a certain extent during connection. At this time, the mating strip 8 can be inserted into the mating groove 5, and then it can be firmly locked in the mating groove 5 by the deformation and reset of the mating strip 8, which facilitates subsequent fastening and enhances the connection stability.

[0034] In one embodiment, the orientation of the connecting metal strip 18 and the orientation of the filling metal strip 19 are both parallel to the rotation trajectory of the winding drum 12. The orientation of the connecting metal strip 18 and the filling metal strip 19 is to ensure that they can fit against the surface of the winding drum 12 when it rotates, thereby avoiding the misalignment and bending of the fabric surface during winding due to the perpendicular orientation, which would affect the fabric winding operation.

[0035] Working Principle: In actual use, two sets of protective shells 1 can be installed in designated positions for convenient subsequent use. Solar panels 13 can then be installed in locations that receive sunlight. The solar panels 13 can perform photoelectric conversion to generate solar power. The generated electricity is converted by the inverter inside the control box 15 and stored in the battery 14. The battery 14 can then power the motors 2 and other equipment, thus reducing overall energy consumption. The rotation of the two motors 2 causes the fabric body 4 to move via the winding drum 12, achieving the shading operation. As usage time increases, when the fabric body 4 becomes damaged, personnel only need to remove the fastening screws 7 on the corresponding surface of the fabric body 4 to replace the damaged fabric. Then, simply reinstalling the intact fabric completes the canopy reconstruction. Overall maintenance reduces waste of intact fabric and eliminates the need for processing the entire fabric, improving maintenance convenience and overall practicality, making it easier to use. During replacement, simply insert the butt joint strip 8 at one end of the intact fabric surface into the butt joint groove 5 of another set of intact fabric surfaces to achieve the fabric butt joint operation. Since both the butt joint strip 8 and the butt joint groove 5 are equipped with magnetic strips 3, a certain degree of pre-fixation can be achieved through magnetic adsorption when the two are aligned, thereby reducing the support effect on the fabric surface afterward. Then, the fastening screw 7 can be installed through the fastening groove 6. At this time, the fastening screw will pass through the filler metal strip 19 in the butt joint strip 8 and the connecting metal strip 18 in the butt joint groove 5 to form a threaded connection, so that the butt joint strip 8 and the butt joint groove 5 are aligned. The docking groove 5 can be used stably, thus avoiding breakage during subsequent pulling and moving, which would damage the fabric and cause loss of the shielding effect. At the same time, the metal setting of the filling metal strip 19 and the connecting metal strip 18 can improve the connection strength between the fabric surfaces. The structure of the metal strip will not affect the subsequent winding and coiling operation of the winding spool 12, thus ensuring that the structure can be used normally. After the connection is completed, the fastening groove 6 can be sealed by the shielding strip 17 to prevent the structure from being exposed. The device as a whole has the advantages of convenient maintenance, low maintenance loss, and strong practicality.
