Abstract
Description
Technical Field
[0001] This application relates to the field of awning technology, and more specifically, to a caravan awning. Background Technology
[0002] RV awnings are outdoor sunshade devices designed specifically for RVs. They can be flexibly unfolded or stored on the side of the RV. When unfolded, they can block sunlight and protect the surrounding area from a little wind and rain, creating a cool and comfortable outdoor space. When stored, they do not take up too much space in the RV. They are suitable for outdoor scenarios such as camping and resting during RV travel, combining practicality and ease of use, and enhancing the outdoor experience of RVs.
[0003] In practice, RV awnings often require manual and laborious adjustment of the support structure during deployment, making it difficult to achieve a smooth and stable deployment. Furthermore, the stability of the support structure after deployment needs improvement. When storing, not only does the awning fabric need to be manually arranged, but irregular storage can also lead to excessive space occupation. Overall, the ease of operation is insufficient, which has a certain impact on the awning needs and space utilization of RVs when used outdoors. Utility Model Content

[0018] The present application will be further described in detail below with reference to the accompanying drawings.
[0019] Reference Figures 1-3 This application provides a RV sunshade, including a drive frame 1. A storage tube 3 is fixedly connected to the upper end of the drive frame 1. A sunshade component 5 is provided inside the storage tube 3. An extension strip 6 is provided on one side of the storage tube 3. A pair of cross-shaped support strips 7 are provided between the drive frame 1 and the extension strip 6, and the middle of the two support strips 7 are hinged to each other. A flip block 8 is hinged to both ends of the support strip 7. A limit slider 9 is fixedly connected to one end of the support strip 7 near the flip block 8 on the extension strip 6. A limit groove 10 is opened on the end face of the extension strip 6 near the support strip 7, and the two limit sliders 9 are slidably connected in the limit groove 10. A double-ended threaded rod 11 is rotatably connected inside the drive frame 1, and the two ends of the double-ended threaded rod 11 have opposite thread directions. The outer walls of both ends of the double-ended threaded rod 11 are rotatably connected by threads. There is a movable block 12. The drive frame 1 has a limit groove 14 on the end face near the support bar 7. A pair of connecting blocks 13 are slidably connected inside the limit groove 14. One end of the connecting block 13 is fixedly connected to the movable block 12, and the other end of the connecting block 13 is fixedly connected to the flip block 8 at the other end of the support bar 7. One end of the drive frame 1 is fixedly connected to a servo motor 2, and the output end of the servo motor 2 is fixedly connected to a double-headed threaded rod 11. By starting the servo motor 2, the double-headed threaded rod 11 drives the movable block 12 and the connecting block 13 to move. The connecting block 13 slides in the limit groove 14 to ensure smooth movement, thereby pulling the support bar 7 to unfold through the cooperation of the flip block 8, the limit slider 9 and the limit groove 10, and pushing the extension bar 6 to smoothly pull out the sunshade component 5. No manual operation is required, and the support structure is stable after unfolding.
[0020] The sunshade assembly 5 includes a fixed rod 501 fixedly connected inside the storage cylinder 3. A rotating cylinder 502 is sleeved around the fixed rod 501. A fixed torsion spring 503 is sleeved on the outer wall of the fixed rod 501. A connecting groove 4 is opened on the lower side of one side of the outer wall of the storage cylinder 3. A waterproof sunshade cloth 504 is fixedly connected to the outer wall of the rotating cylinder 502. One end of the waterproof sunshade cloth 504 extends out of the connecting groove 4 and is fixedly connected to the extension strip 6. The inner wall of the connecting groove 4 is tightly attached to the waterproof sunshade cloth 504 to facilitate the blocking of impurities during recycling. One end of the fixed torsion spring 503 is fixedly connected to the fixed rod 501, and the other end of the fixed torsion spring 503 is fixedly connected to the rotating cylinder 502. The waterproof sunshade cloth 504 can effectively block sunlight and rain, improving the comfort of outdoor use. When storing, the servo motor 2 can be reversed to retract the support bar 7 and reset the extension bar 6. The fixed torsion spring 503 will automatically release its stored force, driving the rotating cylinder 502 to wrap and store the waterproof sunshade cloth 504 inside the storage cylinder 3. There is no need to manually arrange the cloth. After storage, the structure is compact and does not take up too much space. The overall operation is simple, taking into account both practicality and convenience.
[0021] Working Principle: Install the drive frame 1 and storage tube 3 into the designated position on the RV. When the awning is unfolded, the servo motor 2 at one end of the drive frame 1 is activated. The output of the servo motor 2 drives the double-threaded rod 11 inside the drive frame 1 to rotate. Since the threads at both ends of the double-threaded rod 11 are in opposite directions, the rotation of the double-threaded rod 11 causes the two moving blocks 12 on the outer wall to move closer to each other along the double-threaded rod 11. The moving blocks 12 drive the connecting block 13, which is fixedly connected to it, to slide within the limiting groove 14 of the drive frame 1. The connecting block 13 pulls the flipping block 8 at one end of the support bar 7 to move. The support bars 7 are hinged together in the middle. Under the pull of the flipping block 8, the two intersecting support bars 7 gradually unfold, and the flipping block 8 at the other end of the support bar 7 moves accordingly. The flipping block 8 at the end of the support bar 7 near the extension bar 6 drives the limiting slider 9 to slide within the limiting groove 10 of the extension bar 6, pushing the extension bar 6 away from the drive frame 1.
[0022] The extension bar 6 pulls one end of the waterproof sunshade cloth 504, causing the waterproof sunshade cloth 504 to be pulled out from the connecting groove 4 of the storage cylinder 3. The waterproof sunshade cloth 504 pulls the rotating cylinder 502 to rotate around the fixed rod 501 inside the storage cylinder 3. The fixed torsion spring 503 on the outer wall of the fixed rod 501 is twisted and stored until the extension bar 6 moves to the preset position, the servo motor 2 is turned off, and the sunshade is fully deployed.
[0023] When retracting the sunshade, the servo motor 2 is started in reverse, the double-headed threaded rod 11 rotates in the opposite direction, and the two moving blocks 12 move away from each other, causing the connecting block 13 to pull the support bar 7 to flip and retract. The support bar 7 pushes the extension bar 6 towards the drive frame 1, and the waterproof sunshade cloth 504 is no longer under tension. The fixed torsion spring 503 releases its stored force, causing the rotating cylinder 502 to rotate in the opposite direction, winding the waterproof sunshade cloth 504 back onto the outer wall of the rotating cylinder 502, and the waterproof sunshade cloth 504 is collected into the storage cylinder 3 through the connecting groove 4. Once the extension bar 6 is in contact with one side of the storage cylinder 3, the servo motor 2 is turned off, and the sunshade is retracted.
[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
