Description

Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a roll-up structure for a covered wagon rain curtain. Background Technology

[0002] With the popularization of short-distance transportation, covered wagons are widely used in daily travel, logistics distribution and scenic spot sightseeing due to their economical, practical, flexible and convenient features. In order to improve the driving and riding comfort experience, especially in severe weather conditions such as rain, snow and strong winds, covered wagons are usually equipped with roof and side shielding devices to block the wind and rain. However, existing side-shading devices for covered wagons mostly use simple soft curtains or transparent plastic sheets, and their structural design is relatively simple and crude. This traditional protection method has significant technical defects: on the one hand, due to the lack of effective guidance and rigid support structure on the side, the soft curtain is only connected by the suspension point at the top. When the vehicle is traveling at high speed or encounters strong crosswinds, the soft curtain is very easy to flutter violently, bulge, or even be blown directly away from the door frame, causing rainwater to enter the vehicle with the wind, which seriously affects the shading effect and driving safety. On the other hand, the storage method of this simple soft curtain is also extremely inconvenient. When the curtain is not needed, the driver usually needs to manually roll it up layer by layer and tie it with straps or rope buckles. This process is not only cumbersome and time-consuming, but the curtain after manual rolling is often piled up messily. Hanging on the top of the door frame not only occupies the limited head space inside the car, but also destroys the overall appearance and aesthetics of the vehicle. In addition, the fixing straps that are exposed to the outside for a long time are also prone to aging and breakage, which further reduces the service life of the device. Therefore, this utility model proposes a roll-up structure for rain curtains on covered wagons to solve the shortcomings of the existing technology, such as the lack of effective guidance for the soft curtains on the sides of covered wagons, resulting in poor wind resistance and sealing performance, as well as the cumbersome and unsightly storage and fixing operations. Summary of the Invention

[0003] In view of the problems existing in the existing technology of the rain curtain retraction structure of covered wagons, such as poor wind-guiding performance, rain curtains being easily blown up by the wind leading to sealing failure, and the traditional soft curtain storage relying on manual rolling, which is cumbersome and affects the appearance of the vehicle and the driver's vision, this utility model aims to provide a rain curtain retraction structure of covered wagons with improved structure that can effectively solve the above problems.

[0004] This utility model provides a canopy rain curtain retraction structure, including: a frame, a canopy fixedly installed on the top of the frame, and a retraction mechanism installed on the canopy; The carport has vertically oriented fixing grooves on both sides of the door frame. The winding mechanism includes a long rod that is embedded and fixed inside the fixing grooves. The long rod has a long groove extending along its length on the side facing the center of the door frame. The winding mechanism also includes a storage box horizontally disposed on the top of the carport door frame. The storage box has fixing components at both ends of its openings. Each fixing component includes a fixing block fixedly connected to the end of the storage box. The storage box is fixedly connected to the top of the carport door frame via the fixing blocks on both sides. The storage box has a rotating rod inside, with both ends rotatably connected to the inner sidewalls of the fixing blocks on both sides. A roller blind is wound around the outer periphery of the rotating rod, and a bottom rod is fixedly connected to the bottom of the roller blind. The two edges of the roller blind slide into the long grooves of the long rods on both sides. Both ends of the bottom rod extend into the long grooves and can slide along them. The bottom rod has a magnetic attraction component inside. When the bottom rod slides to the bottom of the long rod, it is magnetically fixed to the bottom of the carport door frame.

[0005] Preferably, the cross-sectional shape of the long rod is adapted to the cross-sectional shape of the fixing groove, and after the long rod is embedded in the fixing groove, the outer surface of the long rod is on the same plane as the outer surface of the door frame of the carport.

[0006] Preferably, the fixing block has an L-shaped structure, with one side of the fixing block fixedly connected to the storage box, and the other side of the fixing block attached to the inner wall of the carport door frame and fixedly connected to the carport by bolts.

[0007] Preferably, a planar spiral spring is provided inside the connection between the rotating rod and the fixed block. One end of the planar spiral spring is fixedly connected to the rotating rod, and the other end is fixedly connected to the fixed block, which is used to generate a reverse rewinding torque when the roller shutter is pulled down.

[0008] Preferably, the bottom of the storage box has an opening along its length, the roller blind extends through the opening to the outside of the storage box, and the width of the bottom rod is greater than the width of the opening, so as to prevent the bottom rod from being completely retracted into the storage box.

[0009] Preferably, the inner wall of the long groove is provided with sealing strips on both sides, and the two side edges of the roller blind are clamped between the sealing strips to achieve a sliding seal between the roller blind and the long rod.

[0010] Preferably, the bottom of the door frame of the vehicle frame is provided with a matching magnet corresponding to the position of the bottom rod, for mutual attraction with the magnetic attracting component inside the bottom rod.

[0011] Preferably, the bottom rod has a handle on the side facing away from the vehicle interior. The handle is integrally formed or fixedly connected to the bottom rod, and is used for the user to manually apply downward force.

[0012] This utility model has the following beneficial effects: 1. This utility model solves the problems of existing carport rain curtains being mostly simple external hanging types, inconvenient to store, and affecting the overall appearance of the vehicle by opening a fixing groove on the carport door frame and embedding a long rod, combined with a storage box on the top and a rollable curtain. It achieves the technical effect that the rain curtain can be completely hidden and stored when not in use, maintaining the smooth and beautiful lines of the vehicle body, and can be quickly unfolded to shield against wind and rain when in use. Moreover, the guide rail structure is integrated with the vehicle body, effectively reducing wind resistance during driving.

[0013] 2. This utility model solves the problem that traditional rain curtains are easily blown up and fluttered by side winds during vehicle movement, thus losing their shielding and protective functions, by opening a long groove on the inner side of the long rod and restricting the two sides of the roller blind and the end of the bottom rod inside the long groove for sliding guidance. It achieves the technical effect of smooth and stable lifting and lowering of the roller blind, significantly enhanced wind resistance, good edge sealing, and effective prevention of rainwater intrusion from the side seams.

[0014] 3. This utility model integrates a magnetic suction component inside the base rod and sets a matching suction structure at the bottom of the frame. It uses magnetic attraction to counteract the tension of the rewind spring, solving the problem that existing roller blinds usually require cumbersome mechanical buckles or straps for fixing after being pulled down, resulting in low operating efficiency. It achieves the technical effect of automatically attracting and locking when pulled down to the bottom, fixing it firmly without rebounding, and allowing for easy opening and closing with one hand, greatly improving the convenience of use.

[0015] 4. This utility model solves the problem of difficulty in installing and positioning the winding mechanism on the specific shape of the carport door frame by bolting the two ends of the storage box to the inner side wall of the carport door frame with an L-shaped fixing block. This achieves the technical effect of making full use of the internal space of the door frame, having a stable and reliable installation structure, and being able to effectively withstand the bumps and vibrations of the vehicle.

[0018] Reference Figures 1 to 4 This utility model provides a rain curtain retraction structure for covered wagons, which aims to solve the problems of existing covered wagons lacking effective side protection in bad weather and the traditional curtains being not securely fixed and difficult to store.

[0019] like Figure 1 and Figure 2 As shown, the main structure of the canopy rain curtain retractable structure includes a frame 3, a canopy 1 fixedly installed on the top of the frame 3, and a retractable mechanism 2 installed on the canopy 1. The frame 3 serves as the supporting foundation structure of the entire vehicle, providing driving and riding space and mounting carriers for various components. The canopy 1 serves as the top cover, used to shield from rain and snow above and to provide a mounting base for the retractable mechanism 2. The retractable mechanism 2 is constructed in a gate-shaped structure to realize the retractable shielding function of the rain curtain.

[0020] To achieve integrated installation of the winding mechanism 2 and the carport 1, the two side walls of the door frame of the carport 1 are provided with fixing grooves 26 in the vertical direction. The winding mechanism 2 includes a long rod 22 that is embedded and fixed inside the fixing groove 26. The long rod 22 serves as a lateral guide rail, and its cross-sectional shape is adapted to the cross-sectional shape of the fixing groove 26. After the long rod 22 is embedded in the fixing groove 26, the outer surface of the long rod 22 is on the same plane as the outer surface of the door frame of the carport 1 to ensure the flatness of the vehicle body appearance and reduce wind resistance.

[0021] The long rod 22 has a long groove 23 extending along its length on the side facing the center of the door frame. The long groove 23 runs through the length of the long rod 22 and is used to limit and guide the edge of the rain curtain to prevent the rain curtain from coming off under the action of wind. The rolling mechanism 2 also includes a storage box 21 that is horizontally set at the top of the door frame of the carport 1. The storage box 21 is located between the tops of the two long rods 22 and is used to hold the rolled-up rain curtain assembly. The two ends of the storage box 21 are provided with fixing components 27. The storage box 21 is stably connected to the top of the door frame of the carport 1 through the fixing components 27, thereby forming a complete shelter frame at the door frame of the carport 1.

[0022] Reference Figure 3 and Figure 4The fixing component 27 includes fixing blocks 272 fixedly connected to the openings at both ends of the storage box 21. The fixing blocks 272 have an L-shaped structure and several mounting holes for fasteners are provided on the fixing blocks 272. The fixing blocks 272 are connected to the inner side of the top of the door frame of the carport 1 by bolts passing through the mounting holes in a threaded fastening manner. Its function is to firmly suspend the storage box 21 on the top of the carport 1 and close the end face of the storage box 21 to protect the internal mechanism.

[0023] The storage box 21 has a rotating rod 271 inside. The two ends of the rotating rod 271 are rotatably connected to the inner sidewalls of the two fixed blocks 272 on both sides. A planar spiral spring is provided between the rotating rod 271 and the fixed block 272. The planar spiral spring is used to store energy and provide the rotating rod 271 with the reverse winding torque. A roller blind 24 is fixedly connected to and wound around the outer circumference of the rotating rod 271. A bottom rod 25 is fixedly connected to the bottom of the roller blind 24. The bottom rod 25 is used to apply gravity traction to the roller blind 24 and serves as an operating handle.

[0024] Meanwhile, the long rod 22 is provided with a corresponding long groove 23 for accommodating the edge of the roller blind 24 and the end of the bottom rod 25. In the assembled state, the two sides of the roller blind 24 are respectively embedded and slidably fitted into the long groove 23 of the long rod 22, and the two ends of the bottom rod 25 also extend into the interior of the long groove 23 and can slide up and down along the long groove 23. This embedded track and slider structure ensures the stability of the roller blind 24 during the pulling down and retraction process, and effectively prevents the roller blind 24 from being blown away by the wind and detached from the constraint of the long rod 22.

[0025] Regarding the setting of the sealing strip, those skilled in the art can attach or embed fleece strips or rubber strips on both sides of the inner wall of the long groove 23 to further enhance the sealing performance between the roller shutter 24 and the long rod 22. The specific material selection is a well-known technology in the art and will not be elaborated here.

[0026] As a preferred embodiment, in order to ensure the integrity of the vehicle body appearance and reduce wind resistance noise during vehicle operation, the cross-sectional profile of the long rod 22 is designed to precisely match the internal profile of the fixing groove 26. When the long rod 22 is fully embedded in the fixing groove 26, the outer surface of the long rod 22 facing away from the center of the door frame is kept on the same plane as the outer surface of the door frame of the canopy 1, thereby eliminating the visual abruptness and aerodynamic interference caused by the convex structure.

[0027] As another preferred embodiment, in order to ensure reliable positioning of the roller shutter 24 after it is pulled down to the bottom and to prevent it from automatically retracting under the action of rewind torque, please refer to... Figure 3 and Figure 4The bottom rod 25 has a magnetic suction component integrated in its internal cavity. Correspondingly, a ferromagnetic metal suction surface is provided in the bottom area of ​​the frame 3 door frame below the canopy 1 for strong magnets to attract. The magnetic attraction overcomes the rewinding torque of the rotating rod 271 and firmly locks the bottom rod 25 to the bottom of the door frame, thereby ensuring the sealing and stability of the rain curtain in the closed state.

[0028] As another preferred embodiment, in order to prevent the bottom rod 25 from accidentally retracting into the storage box 21 when the roller shutter 24 is fully retracted, making it difficult to pull out again, the strip opening at the bottom of the storage box 21 along the length direction has a specific width dimension. The width dimension of the bottom rod 25 is designed to be larger than the width of the strip opening. Utilizing the principle of dimensional interference, the bottom rod 25 will be blocked outside when it rises to the bottom of the storage box 21, playing a limiting and stopping role.

[0029] As another preferred embodiment, in order to facilitate manual operation of the roller blind 24 by the user inside or outside the vehicle, the bottom rod 25 may also be integrally formed with a handle structure on the side surface or bottom surface facing away from the vehicle. The handle surface may be provided with anti-slip texture so that the user can apply force to overcome the torsion spring resistance of the rotating rod 271 and pull the roller blind 24 down.

[0030] The working principle is as follows: When encountering rainy or snowy weather, or when needing to shield from side wind and rain, the user holds the handle on the bottom rod 25 and applies downward pulling force. Under the action of pulling force, the rotating rod 271 overcomes the torque resistance of the internal planar spiral spring and begins to rotate in the forward direction, thereby gradually releasing the roller blind 24 from the storage box 21. During this process, the two sides of the roller blind 24 are always restricted to sliding inside the long groove 23 of the long rod 22, and the two ends of the bottom rod 25 also descend smoothly under the guidance of the long groove 23. This lateral limiting structure throughout the process effectively prevents the roller blind 24 from fluttering or billowing due to external wind force during the unfolding process.

[0031] When the bottom rod 25 is pulled to the bottom of the long rod 22, the powerful magnet inside the bottom rod 25 approaches the ferromagnetic metal contact surface at the bottom of the door frame of the frame 3 and generates a strong magnetic attraction force. This magnetic attraction force is greater than the return tension of the spring inside the rotating rod 271, thus firmly locking the bottom rod 25 to the bottom of the door frame, completing the unfolding and fixing of the rain curtain. At this time, the roller blind 24, the long rod 22, the storage box 21 and the bottom rod 25 together form a closed protective barrier, achieving effective shading of the side of the carport 1.

[0032] When the weather clears up or the rain curtain is no longer needed, the user only needs to pull the bottom rod 25 upwards or pry it outwards slightly to disengage the magnetic attraction between the bottom rod 25 and the frame 3. Then, under the torque released by the internal planar spiral spring of the rotating rod 271, the rotating rod 271 rotates in the opposite direction, automatically rolling up the curtain 24. The bottom rod 25 then moves upwards along the long groove 23 until it is blocked at the curtain outlet of the storage box 21, completing the storage process. At this time, the long rod 22 remains flat with the carport 1 due to its embedded design, without affecting the daily appearance and driving of the vehicle.
