A trapezoidal sliding fixing block 10 is installed on one side of the protective cover 1, making it easy to install the entire device on an RV or different beams, increasing the product's versatility. An opening is longitudinally formed on the other side, with a rainproof baffle 13 at the top to protect the lower bidirectional lead screw 5 from corrosion and aging caused by rainwater. The bidirectional lead screw 5 is located at the bottom of the opening. The rainproof baffle 13 and the bidirectional lead screw 5 are mounted on the protective cover 1. The main shaft 16 is longitudinally arranged inside the protective cover 1, facilitating the installation of the entire RV... The rain shelter 3 retracts; connecting blocks 17 are installed on both sides of the middle of the main shaft 16, and a universal joint 12 is installed at the front end of the main shaft 16. Through the universal joint 12, the stepper motor 18 can transmit force normally even if it is offset due to external impact; the other end of the universal joint 12 is equipped with a stepper motor 18, and the other end of the universal joint 12 is connected to the output shaft of the stepper motor 18. The surface of the stepper motor 18 has a fixing strap 15, which is used to fix the stepper motor 18 and avoid the situation where it is easily offset due to human impact; the stepper motor 18 is installed inside the housing 2 through the fixing strap 15, and a rotating block 11 is installed at the rear end of the main shaft 16. Through the rotating block 11, the main shaft 16 is fixed and the stability of the main shaft 16 during operation is increased. A bearing 4 is connected to the outside of the rotating block 11, which is used to ensure that the entire main shaft 16 can run smoothly; the bearing 4 is installed inside the protective cover 1.

[0026] In this invention, the two ends of the bidirectional lead screw 5 are threaded with movable blocks 6, which facilitate the smooth outward extension of the rain shelter 3, ensuring the product's fluidity. Furthermore, a micro motor 14 is provided at the front end of the bidirectional lead screw 5, which facilitates its operation. The micro motor 14 is connected to the bidirectional lead screw 5 via a coupling, and a fixing plate 19 is fixedly attached to the bottom surface of the micro motor 14. The micro motor 14 is installed inside the outer casing 2 via the fixing plate 19, which protects and secures the micro motor 14 from corrosion by rainwater and human-caused damage. Damage; A sliding opening is provided on one side of the main shaft 16, and a sliding block 20 is provided in the sliding opening. A slot is provided on one side of the sliding block 20, and a rain shelter 3 is installed in the slot. A support rod 7 is movably hinged to the other side of the moving block 6.

A tension rod 9 is movably hinged to the other end of the support rod. One side of the tension rod 9 is connected to the other end of the rain shelter 3.

[0027] Working principle: First, fix the main shaft 16 and connecting block 17 in place. Then, fix the main shaft 16 on the rotating block 11, ensuring that one end of the rotating block 11 is connected to the bearing 4. The other end of the main shaft 16 is fixed to the universal joint 12. One end of the universal joint 12 is connected to the stepper motor 18. A fixing strap 15 is attached above the stepper motor 18 and is installed on the fixing buckle of the outer casing 2. The sliding block 20 is located inside the main shaft 16, and the other end of the sliding block 20 is connected to the rain shelter 3. One end of the rain shelter 3 is connected to the tension rod 9. The micro motor 14 is fixed by the fixing plate 19. The support rod 7 is installed on the moving block 6. The moving block 6 is then installed... With the bidirectional lead screw 5 in place, a sliding strip 8 is installed between the two support rods 7. After the circuit wiring is completed and the trapezoidal sliding fixing block 10 is installed on the RV's matching buckle, the entire equipment is considered installed. Power on the equipment and start the stepper motor 18 and the micro motor 14, which will drive the main shaft 16 and the bidirectional lead screw 5 to rotate synchronously. The bidirectional lead screw 5 is connected to the moving block 6. The two moving blocks 6 will drive the support rod 7 to extend and retract as the lead screw moves. The sliding strip 8 will serve as the intermediate mechanism for the extension and retraction of the support rod 7. Thus, the rain shelter 3 will extend when the stepper motor 18 and the micro motor 14 rotate forward and retract when they rotate in reverse.
