Therefore, they should not be construed as limitations on this application.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0021] Figures 1 to 9 As shown, this application provides a retractable flexible solar lighting device, including a solar energy mechanism 1, an energy storage control mechanism 2, and a luminaire 3. The solar energy mechanism 1 includes a first cylindrical body 11, two end caps 12, a notch 13, a spring-loaded assembly 14, a flexible base layer 15, multiple flexible solar panels 16, and a support assembly (not shown in the figure). The first cylindrical body 11 is axially continuous. The two end caps 12 are respectively installed at both ends of the first cylindrical body 11. The notch 13 is opened in the first cylindrical body 11. The spring-loaded assembly 14 is installed between the two end caps 12 and located inside the first cylindrical body 11. The flexible base layer 15 is installed on the spring-loaded assembly 14. Multiple flexible solar panels 16 are all installed on the surface of the flexible base layer 15. The support assembly is installed on the first cylindrical body 11 or the two end caps 12. The energy storage control mechanism 2 includes a second cylindrical body 21, an energy storage module 22, and a control module (not shown in the figure). The second cylindrical body 21 is installed at one end of the first cylindrical body 11, the energy storage module 22 is installed inside the second cylindrical body 21, and the control module is installed inside the second cylindrical body 21 and electrically connected between the multiple flexible solar panels 16 and the energy storage module 22. A lighting device 3 is installed at the end of the second cylindrical body 21 away from the first cylindrical body 11 and is electrically connected to the control module.

[0022] This application provides a retractable flexible solar lighting device that, with the help of flexible solar panels 16, converts solar energy into electrical energy and stores it in an energy storage module 22 via a control module. The energy storage module 22 then provides power to the lighting unit 3 for illumination. With the help of a spring-loaded component 14, multiple flexible solar panels 16 are wound around a first cylindrical body 11 via a flexible base layer 15. Compared to existing technologies, this effectively reduces the size and weight of the lighting device, making it easier to store and carry, applicable to a wider range of scenarios, and improving usability. With the help of a support component, the flexible base layer 15 is supported after it is unfolded, facilitating the absorption of solar energy by the multiple flexible solar panels 16 and improving power generation efficiency. Furthermore, the support component also facilitates the placement of the retractable flexible solar lighting device, allowing it to be installed in different scenarios and further enhancing usability.

[0023] In one embodiment of this application, please refer to Figures 1 to 9 The support assembly includes multiple fixing plates 17, two folding brackets 18 and folding bracket 19. The multiple fixing plates 17 are all installed on the side of the flexible base layer 15 facing away from the flexible solar panel 16. The two folding brackets 18 are all installed on the outer periphery of the first cylinder 11 and are configured to support the flexible base layer 15 through the multiple fixing plates 17 and are arranged at intervals along the axial direction of the first cylinder 11. The folding bracket 19 is installed on the end cap 12 away from the second cylinder 21 and is used to support or suspend the first cylinder 11.

[0024] This configuration, with the assistance of folding bracket 18, allows the flexible base layer 15 to be supported by multiple fixing plates 17 after it is unfolded, preventing it from retracting back into the first cylinder 11 under the action of the rebound component 14. It also allows multiple flexible solar panels 16 to unfold, facilitating their absorption of solar energy. Folding bracket 2 19 allows the lighting device to be suspended and supported. Furthermore, it can be folded for handheld use, enabling different placement methods depending on the application scenario, thus offering a wide range of applications. Both folding bracket 18 and folding bracket 2 19 are foldable, reducing their footprint and making them easy to carry and use.

[0025] In one embodiment of this application, please refer to the following: Figures 1 to 9The folding bracket 18 includes a mounting block 181, a rotating shaft 182, a locking structure 183, a swing rod 184, a telescopic bracket 185, and multiple fixing parts 186. The mounting block 181 is mounted on the outer periphery of the first cylinder 11. The rotating shaft 182 passes through the mounting block 181. The locking structure 183 is mounted on one end of the rotating shaft 182 and can lock the rotating shaft 182 to the mounting block 181. The swing rod 184 is mounted on the end of the rotating shaft 182 away from the locking structure 183. The telescopic bracket 185 is mounted on the swing rod 184 and can extend and retract along the axial direction of the rotating shaft 182. Multiple fixing parts 186 are all mounted on the telescopic bracket 185 and can move equidistantly along the axial direction of the rotating shaft 182 under the drive of the telescopic bracket 185, and are correspondingly arranged with multiple fixing plates 17.

[0026] With this configuration, under the action of the rotating shaft 182, the swing rod 184 can rotate relative to the mounting block 181, and the telescopic bracket 185 can swing relative to the first cylinder 11, facilitating the storage of the telescopic bracket 185, making adjustment convenient, and easy to store. Under the action of the telescopic bracket 185, it can retract relative to the swing rod 184, further reducing the space occupied. Under the action of multiple fixing members 186, after the flexible base layer 15 is unfolded, it can be fixed by multiple fixing plates 17, thereby preventing the flexible base layer 15 and multiple flexible solar panels 16 from retracting into the first cylinder 11.

[0027] In one embodiment of this application, see [reference] Figures 1 to 9 The mounting block 181 has a limiting hole 187. The rotating shaft 182 includes a limiting rod 1821 and a locking rod 1822. The limiting rod 1821 is mounted on the swing rod 184 and slidably engaged in the limiting hole 187. The locking rod 1822 is mounted on the end of the limiting rod 1821 away from the swing rod 184 and is configured to lock the limiting rod 1821 in the limiting hole 187 by a locking structure 183.

[0028] It should be noted that in this embodiment, the locking structure 183 is a locking nut, which is screwed onto the outer periphery of the locking rod 1822 to lock the limiting rod 1821 into the limiting hole 187. Of course, in other embodiments, the locking structure 183 can also be a pin, which passes through the locking rod 1822 to lock the limiting rod 1821 into the limiting hole 187.

[0029] With this configuration, the mounting block 181 and the rotating shaft 182 can be engaged by the limiting hole 187 and the limiting rod 1821, allowing the folding bracket 18 to be stably held in either the unfolded or folded state. Furthermore, the limiting rod 1821 can slide within the limiting hole 187, and by removing the locking structure 183, the folding bracket 18 can be switched between the unfolded and folded states for convenient adjustment.

[0030] In one embodiment of this application, please refer to Figures 1 to 9 The telescopic support 185 includes multiple hinge rods 1851 and multiple hinge rods 1852. The multiple hinge rods 1851 are arranged in parallel, and one end of one of the hinge rods 1851 is hinged to the swing rod 184. The multiple hinge rods 1852 are arranged in parallel, and one end of one of the hinge rods 1852 is hinged to the swing rod 184. The multiple hinge rods 1851 and multiple hinge rods 1852 are interleaved and hinged to each other.

[0031] This configuration allows multiple hinge rods 1851 and 1852 to combine and form a parallelogram mechanism, facilitating retraction, expansion, and adjustment. Furthermore, as the hinge rods 1851 and 1852 retract and expand, they drive multiple fixing members 186 to move axially along the rotation axis 182, enabling the fixing members 186 to align with the fixing plates 17, thus facilitating the fixation of the flexible base layer 15.

[0032] In one embodiment of this application, please refer to the following: Figures 1 to 9 The fastener 186 includes a connecting frame 1861, a fixing rod 1862, and a locking structure 2 (not shown in the figure). The connecting frame 1861 is hinged to one end of the hinge rod 1851 near the flexible base layer 15 and the other end of the hinge rod 2 1852 near the flexible base layer 15. The fixing rod 1862 is installed on the connecting frame 1861 and passes through the fixing plate 17. The locking structure 2 is installed on the fixing plate 17 and is located on the side of the fixing plate 17 facing away from the telescopic bracket 185, and is configured to lock the fixing plate 17 to the fixing rod 1862.

[0033] It should be noted that in this embodiment, the second locking structure is a pin, which passes through the fixing rod 1862 to lock the fixing rod 1862 to the fixing plate 17. Of course, in other embodiments, the second locking structure can also be a locking nut, which is screwed onto the outer periphery of the fixing rod 1862 to lock the fixing rod 1862 to the fixing plate 17.

[0034] This configuration, under the action of the connecting frame 1861, prevents the fixed rod 1862 from directly contacting the hinge rod 1851 and the hinge rod 2 1852, thus avoiding interference with the rotation of the hinge rod 1851 and the hinge rod 2 1852, and facilitating the adjustment of the hinge rod 1851 and the hinge rod 2 1852. Under the action of the locking structure 2, the fixed rod 1862 can be locked to the fixed plate 17, which helps to improve the structural stability between the fixed rod 1862 and the fixed plate 17. During use, it can prevent the fixed plate 17 from detaching from the fixed rod 1862, thereby preventing the flexible base layer 15 and the multiple flexible solar panels 16 from retracting.

[0035] In one embodiment of this application, see [reference] Figures 1 to 9 The folding bracket 18 also includes a slide groove 188 and a limiting bracket 189. The slide groove 188 is formed on the swing rod 184, and the limiting bracket 189 is connected to the end of the swing rod 184 away from the rotation axis 182. The telescopic bracket 185 also includes a connecting bracket 1853, a slide rod 1854, a screw rod 1855, and a rotating sleeve 1856. The connecting bracket 1853 is hinged to the hinge rod 1852. The slide rod 1854 is installed on the connecting bracket 1853 and passes through the slide groove 188. The screw rod 1855 is connected to the slide rod 1854 and passes through the connecting bracket 1853. The rotating sleeve 1856 is screwed to the screw rod 1855 and is limited within the limiting bracket 189.

[0036] This configuration, under the action of the limiting bracket 189, prevents the slide rod 1854 and screw rod 1855 from directly contacting the hinge rod 1852, thus avoiding interference with the rotation of the hinge rod 1852. The slide rod 1854 facilitates the installation of the screw rod 1855, and the slide groove 188 guides the movement of the screw rod 1855, ensuring it can only move along the slide groove 188, thus improving the stability of its movement. The rotating sleeve 1856 drives the screw rod 1855 to move along the slide groove 188, which in turn drives the rotation of multiple hinge rods 1851 and multiple hinge rods 1852, allowing the telescopic bracket 185 to unfold and retract easily. Furthermore, the rotating sleeve 1856 and screw rod 1855 provide self-locking, ensuring the telescopic bracket 185 remains stably in the unfolded or folded state.

[0037] In one embodiment of this application, please refer to Figures 1 to 9The folding bracket 19 includes a threaded sleeve 191, a fixed plate 192, a sliding plate 193, multiple hinge rods 194, multiple hinge rods 195, multiple snap-fit ​​grooves 196, snap-fit ​​pieces 197, a screw 198, and a hook 199. The threaded sleeve 191 is installed on the end cover 12. The fixed plate 192 is connected to the end of the threaded sleeve 191 away from the end cover 12. The sliding plate 193 is sleeved on the threaded sleeve 191 and can slide along the axial direction of the threaded sleeve 191. One of the multiple hinge rods 194... One end is hinged to the sliding disk 193. Each hinge rod 194 and the fixed disk 192 are hinged to a hinge rod 195. Multiple snap-fit ​​grooves 196 are opened on the outer periphery of the threaded sleeve 191 and are spaced apart along the axial direction of the threaded sleeve 191. The snap-fit ​​member 197 is installed on the sliding disk 193 and is configured to snap onto the threaded sleeve 191 through any snap-fit ​​groove 196. The screw 198 is screwed into the threaded sleeve 191. The hook 199 is installed at the end of the screw 198 away from the end cover 12.

[0038] With this configuration, under the action of the sliding disc 193, the multiple hinge rods 194 can be brought together facing each other or unfolded facing away from each other through the fixed disc 192 and multiple hinge rods 195, making adjustment convenient. When the multiple hinge rods 194 are unfolded, they can support the first cylinder 11 effectively. Under the action of the snap-fit ​​member 197, the sliding disc 193 can be fixed to the outer periphery of the threaded sleeve 191 through multiple snap-fit ​​grooves 196, thus ensuring that the multiple hinge rods 194 are stably held in the unfolded or gathered state. Furthermore, under the action of the snap-fit ​​member 197, the angle between the multiple hinge rods 194 and the sliding disc 193 can be adjusted, thereby adjusting the position of the illuminator 3 and improving ease of use. Under the action of the hook 199, the first cylinder 11 can be suspended at a designated position. By rotating the second screw 198, the screw 198 can be moved relative to the screw sleeve 191, thereby adjusting the position of the hook 199 and controlling the position of the lighting, which helps to improve ease of use. In addition, the screw sleeve 191 and the second screw 198 can achieve self-locking, which helps to improve the structural stability between the hook 199 and the first cylinder 11.

[0039] In one embodiment of this application, please refer to the following: Figures 1 to 9 The snap-fit ​​component 197 includes a snap-fit ​​rod 1971, a screw 1972, and an elastic structure 1973. The snap-fit ​​rod 1971 passes through the sliding disk 193 and snaps into any snap-fit ​​groove 196. The screw 1972 is screwed into the sliding disk 193. The elastic structure 1973 abuts between the snap-fit ​​rod 1971 and the screw 1972 and is disposed within the sliding disk 193.

[0040] This configuration, with the action of the locking rod 1971 and the locking groove 196, enables locking, thereby fixing the sliding disc 193 to the outer periphery of the threaded sleeve 191. The action of the screw 1972 facilitates the installation of the elastic structure 1973 and prevents it from dislodging from the sliding disc 193. The elastic structure 1973 ensures that the locking rod 1971 always tends to move towards the threaded sleeve 191, guaranteeing that the locking rod 1971 can be locked into any locking groove 196 after alignment, making it convenient to use.

[0041] In one embodiment of this application, see [reference] Figures 1 to 9 The springback assembly 14 includes a central shaft 141 and a plurality of rewind springs 142. The central shaft 141 is mounted between two end caps 12 and located inside the first cylinder 11. The plurality of rewind springs 142 are mounted on the central shaft 141 and are configured to drive the flexible base layer 15 to wind through the notch 13 into the first cylinder 11.

[0042] With this configuration, multiple retraction springs 142 can be fixed under the action of the central shaft 141. Under the action of the multiple retraction springs 142, the flexible base layer 15 always has a tendency to retract into the first cylinder 11. After the fixing plate 17 is removed from the fixing rod 1862, the flexible base layer 15 can automatically wrap around the outer periphery of the multiple retraction springs 142, which is convenient to store and use.

[0043] The working principle of the stretchable and flexible solar lighting device provided in this application is as follows: In use, the user first removes the two locking structures 183 from the locking rod 1822, then pulls the limiting rod 1821 out of the limiting hole 187 on the mounting block 181. After rotating the swing rod 184 ninety degrees, the limiting rod 1821 is re-inserted into the limiting hole 187, and the locking structure 183 is installed back onto the locking rod 1822. At this time, the swing rod 184 is erected from the surface of the first cylinder 11. The user rotates the rotating sleeve 1856 to move the screw 1855 along the slide groove 188 toward the mounting block 181. Driven by the screw 1855, multiple hinge rods 1851 and multiple hinge rods 1852 begin to rotate until the slide rod 1854 moves to the end of the slide groove 188 away from the limiting frame 189, at which point the telescopic bracket 185 is fully extended. After the telescopic bracket 185 is deployed, the user pulls out the flexible base layer 15 from the notch 13 and aligns the multiple fixing plates 17 with the multiple fixing rods 1862. After the multiple fixing plates 17 are fitted onto the multiple fixing rods 1862, the fixing plates 17 and the fixing rods 1862 can be locked by the second locking structure.

[0044] When the first cylinder 11 needs support, the user pulls the sliding plate 193, causing it to move along the threaded sleeve 191 towards the fixed plate 192. Multiple hinge rods 194 and 195 unfold in opposite directions until they stably support the first cylinder 11. When the first cylinder 11 needs suspension, the user pulls the sliding plate 193, causing it to move along the threaded sleeve 191 away from the fixed plate 192 until the hinge rods 194 and 195 are fully converged. The first cylinder 11 is then suspended to the target position via the hook 199.

[0045] One or more embodiments in this application are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of this application. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments in this application should be included within the protection scope of this application.
