Description

Technical Field

[0001] This invention relates to the field of sunshade component technology, specifically to a retractable sunshade component and method for RVs. Background Technology

[0002] As a special type of vehicle that combines living and mobility, motorhomes have been widely used in recent years due to the continued growth of the outdoor camping and long-distance travel market. The windshield of a motorhome is much larger than that of a regular passenger car, and it typically forms a steep angle with the dashboard. Its sunshade requirements differ significantly from those of passenger cars: when parked and camping, occupants want sufficient natural light to maintain a sense of openness, but also need effective sunshade to reduce interior temperature when exposed to direct sunlight; they need complete blackout to ensure privacy during nighttime rest, while also needing flexible adjustments to the range and degree of sunshade to adapt to changes in light intensity at different times of day and in different orientations. For example, patent application CN118238589A discloses an adaptive retractable sunshade for car windows. The fixing mechanism of this adaptive retractable sunshade includes a central beam and two side beams, which are connected by an adjusting assembly located inside the fixing mechanism. The following mechanism includes an inner beam and an outer beam, with the inner beam slidably inserted into the outer beam. The connection between the inner and outer beams is made of elastic material. The following mechanism contains multiple suspension mechanisms that engage with the top of the car window glass. The bottom of the fixing mechanism has multiple tensioning mechanisms. This design can meet the practical needs of various car window specifications. However, the installation methods of the above adaptive retractable sunshade curtains are relatively simple, such as horizontal pull-up installation and vertical lift installation on the windshield, and installation on the window glass between the A-pillar and B-pillar. When a single connection structure or installation posture cannot be adjusted, it is impossible to switch between different installation methods according to different usage scenarios, resulting in poor adaptability. Based on this, the present invention designs a retractable sunshade component and method for RVs to solve the above problems. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the prior art, the present invention provides a retractable sunshade component and method for RVs.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A retractable sunshade assembly for a motorhome includes a first side beam, a second side beam, and a retractable curtain, with both ends of the retractable curtain fixedly installed on the first side beam and the second side beam, respectively. A winding module is installed between the first side beam and the second side beam; Both the first and second side beams are equipped with adjustable adsorption modules. Each adjustable adsorption module includes a rotating plate, a first rotating shaft, and an adsorption unit. The rotating plate is fixedly connected to the first rotating shaft. The two first rotating shafts in the two sets of adjustable adsorption modules are rotatably connected to the first and second side beams, respectively. The adsorption unit is installed on the surface of the rotating plate. An adjustable hook module is installed on the side of the rotating plate.

[0005] Furthermore, a storage compartment is provided on the side of the first side beam near the winding module. The winding module includes a reel, a spool, a damping structure, a coil spring, an elastic rope, and a fixed shell. The fixed shell is fixedly installed inside the storage compartment. The coil spring is embedded in the fixed shell. The reel is fixedly installed on the spool. Both ends of the spool are rotatably connected to the storage compartment. The coil spring is sleeved on the surface of the spool. One end of the elastic rope is wound around the reel, and the other end is fixedly connected to the second side beam. The damping structure is installed between the spool and the storage compartment. The elastic rope passes through a through hole on the surface of the telescopic curtain.

[0006] Furthermore, the adsorption unit includes a base shell and a silicone suction cup. The base shell is embedded in the surface of the rotating plate, and a sealed adsorption cavity is formed inside the base shell. A silicone suction cup is fixedly installed on the side of the base shell near the sealed adsorption cavity, and the silicone suction cup is in communication with the sealed adsorption cavity.

[0007] Furthermore, the adsorption unit also includes a piston block and a pre-tightening spring. A variable volume compensation cavity is provided on the side of the base shell away from the silicone suction cup. The piston block is slidably connected in the variable volume compensation cavity. A vent is provided between the variable volume compensation cavity and the sealed adsorption cavity. The side of the piston block away from the vent is connected to the variable volume compensation cavity through the pre-tightening spring.

[0008] Furthermore, the rotating plate has a recess and a slot on its side, and an installation hole is provided in the recess. The adjustable hook module is installed in the installation hole. The adjustable hook module includes a frustum, a second rotating shaft, a limiting member, a hook body, and a third rotating shaft. The second rotating shaft is rotatably connected in the installation hole. One end of the second rotating shaft is fixedly connected to the frustum. The end of the hook body near the frustum is fixedly connected to the third rotating shaft. The third rotating shaft is rotatably connected to the surface of the frustum. The limiting member is installed on the end of the second rotating shaft away from the frustum.

[0009] Furthermore, a limiting groove is formed on the side of the first side beam near the second side beam, and a first magnetic attractor is installed in the limiting groove. A second magnetic attractor is installed on the second side beam at the position corresponding to the first magnetic attractor.

[0010] Furthermore, it also includes a curtain fixing plate. One end of the telescopic curtain is clamped between the first side beam and the curtain fixing plate, and the other end is clamped between the second side beam and the curtain fixing plate. Fasteners are installed on the surface of the curtain fixing plate, and both the first and second side beams are fixedly connected to the curtain fixing plate by fasteners.

[0011] Furthermore, both the first and second side beams are fixedly connected to rope fixing plates, and fasteners are installed on the surface of the rope fixing plates. Both the first and second side beams are fixedly connected to the rope fixing plates through fasteners. The rope fixing plate on the first side beam slides in contact with the elastic rope, and one end of the elastic rope on the derailleur is fixed to the fastener on the second side beam.

[0012] A retractable sunshade method for RVs includes: S100. Manually rotate the rotating plate with the first rotating shaft as the axis so that the adsorption surfaces of the adsorption units at the first and second side beams are parallel to the telescopic curtain. Adsorb the adsorption unit at the first side beam to one side of the windshield. Pull the second side beam toward the other side to unfold the telescopic curtain and adsorb the adsorption unit at the second side beam to the other side of the windshield. S200. Manually rotate the rotating plate with the first rotating shaft as the axis, so that the adsorption surface of the adsorption unit at the first side beam is perpendicular to the telescopic curtain, and adsorb it at the bottom of the windshield near the RV dashboard. Pull the second side beam toward the RV sun visor to unfold the telescopic curtain. Manually adjust the angle of the rotating plate with the first rotating shaft as the axis, and adjust the angle of the adjustable hook module in conjunction with the adjustment of the angle of the adjustable hook module to hang the adjustable hook module on the RV sun visor.

[0013] Compared with the prior art, the beneficial effects of this invention are as follows: 1. Through the combination of adjustable adsorption module and adjustable hook module, when the user needs to install the sunshade component in different positions, such as the sides of the windshield, between the bottom of the windshield and the sunshade, or between the A-pillar and B-pillar, the adjustable adsorption module and adjustable hook module can be adjusted to different postures according to the needs of the installation scenario, which greatly improves the adaptability of the sunshade component in the RV. 2. By setting up the adsorption unit, under high temperature exposure, when sunlight causes the air in the sealed adsorption chamber to expand due to heat, some of the excess gas will enter the variable volume compensation chamber through the vent. The gas entering the variable volume compensation chamber pushes the piston block to slide upward, and the pre-tightening spring further compresses the volume of the variable volume compensation chamber, thereby increasing the volume and accommodating the thermally expanded air. By maintaining the high temperature pressure difference through passive physical volume change, the stability of the adsorption state is improved. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-8 A retractable sunshade assembly for a motorhome includes a first side beam 1, a second side beam 3, and a retractable curtain 4, with both ends of the retractable curtain 4 fixedly installed on the first side beam 1 and the second side beam 3, respectively. A winding module 2 is installed between the first side beam 1 and the second side beam 3; The first side beam 1 and the second side beam 3 are both equipped with adjustable adsorption modules 7. The adjustable adsorption module 7 includes a rotating plate 71, a first rotating shaft 72 and an adsorption unit 73. The rotating plate 71 is fixedly connected to the first rotating shaft 72. The two first rotating shafts 72 in the two sets of adjustable adsorption modules 7 are respectively rotatably connected to the first side beam 1 and the second side beam 3. The adsorption unit 73 is installed on the surface of the rotating plate 71. An adjustable hook module 8 is installed on the side of the rotating plate 71; The adsorption unit 73 includes a base shell 731 and a silicone suction cup 732. The base shell 731 is embedded in the surface of the rotating plate 71. A sealed adsorption cavity 733 is formed inside the base shell 731. A silicone suction cup 732 is fixedly installed on the side of the base shell 731 near the sealed adsorption cavity 733. The silicone suction cup 732 is in communication with the sealed adsorption cavity 733. A limiting groove 12 is formed on the side of the first side beam 1 near the second side beam 3. A first magnetic attractor 13 is installed in the limiting groove 12. A second magnetic attractor 31 is installed on the second side beam 3 at the position corresponding to the first magnetic attractor 13. The specific form of the first magnetic attractor 13 and the second magnetic attractor 31 is not limited. The first magnetic attractor 13 and the second magnetic attractor 31 can be magnetic blocks, and two sets of magnetic blocks are respectively embedded in the limiting groove 12 and the surface of the second side beam 3. The first magnetic attractor 13 and the second magnetic attractor 31 can be flexible magnetic strips, and two sets of flexible magnetic strips are respectively embedded in the surface of the limiting groove 12 and the second side beam 3. The strips are respectively pasted on the surface of the limiting groove 12 and the second side beam 3. When the second side beam 3 is fixed in the limiting groove 12 by the magnetic attraction of the first magnetic member 13 and the second magnetic member 31, the folded telescopic curtain 4 is compressed between the first side beam 1 and the second side beam 3. The limiting function of the limiting groove 12 can prevent the first side beam 1 and the second side beam 3 from sliding relative to each other. When the first side beam 1 or the second side beam 3 is hit by an external force, if the two slide relative to each other or are misaligned, the telescopic curtain 4 is prone to damage or tearing. In this embodiment, when a retractable sunshade component for a motorhome is working normally, the rotating plate 71 is manually rotated with the first rotating shaft 72 as the axis, so that the adsorption surfaces of the adsorption units 73 at the first side beam 1 and the second side beam 3 are parallel to the retractable curtain 4, and the adsorption units 73 at the first side beam 1 are adsorbed and fixed to one side of the windshield. The second side beam 3 is pulled to the other side to unfold the retractable curtain 4, and the adsorption units 73 at the second side beam 3 are adsorbed and fixed to the other side of the windshield. This is suitable for situations where the width of the retractable curtain 4 is smaller than the width of the motorhome windshield. Manually rotate the rotating plate 71 with the first rotating shaft 72 as the axis, so that the adsorption surface of the adsorption unit 73 at the first side beam 1 is perpendicular to the telescopic curtain 4, and adsorb it at the bottom of the windshield near the RV dashboard. Pull the second side beam 3 towards the RV sun visor to unfold the telescopic curtain 4. Manually adjust the angle of the rotating plate 71 with the first rotating shaft 72 as the axis, and adjust the angle of the adjustable hook module 8 in conjunction with it to hang the adjustable hook module 8 on the RV sun visor. This method is suitable for situations where the width of the telescopic curtain 4 is not less than the width of the RV windshield, and has the characteristics of flexible adjustment, wide applicability and strong practicality.

[0019] Example 2: In some embodiments, such as Figures 1-8 As shown, in a preferred embodiment of the present invention, a storage compartment 11 is provided on the side of the first side beam 1 near the winding module 2. The winding module 2 includes a reel 21, a spool 22, a damping structure 23, a coil spring 24, an elastic rope 25, and a fixing shell 26. The fixing shell 26 is fixedly installed in the storage compartment 11, and the coil spring 24 is embedded in the fixing shell 26. The reel 21 is fixedly installed on the spool 22, and both ends of the spool 22 are rotatably connected to the storage compartment 11. The coil spring 24 is sleeved on the surface of the spool 22. One end of the elastic rope 25 is wound around the spool 21, and the other end is fixedly connected to the second side beam 3. The damping structure 23 is installed between the spool 22 and the storage compartment 11. The damping structure 23 can be designed as a friction damper. Specifically, the friction damper is a shell filled with a high-viscosity fluid. A rotating rod is rotatably connected inside the shell. The shell is fixedly connected to the storage compartment 11. One end of the spool 22 is fixedly connected to the rotating rod. The spool 22 can rotate synchronously with the rotating rod. The elastic rope 25 passes through the through hole on the surface of the telescopic curtain 4. The first side beam 1 and the second side beam 3 are both fixedly connected to the curtain fixing plate 5. One end of the telescopic curtain 4 is clamped between the first side beam 1 and the curtain fixing plate 5, and the other end is clamped between the second side beam 3 and the curtain fixing plate 5. Fasteners 9 are installed on the surface of the curtain fixing plate 5. The first side beam 1 and the second side beam 3 are both fixedly connected to the curtain fixing plate 5 by the fasteners 9. Both the first side beam 1 and the second side beam 3 are fixedly connected to a rope fixing plate 6. Fasteners 9 are installed on the surface of the rope fixing plate 6. The first side beam 1 and the second side beam 3 are both fixedly connected to the rope fixing plate 6 via the fasteners 9. The rope fixing plate 6 on the first side beam 1 is in sliding contact with the elastic rope 25. A guide groove is provided on the surface of the rope fixing plate 6 at this location, and the elastic rope 25 is specifically slidably connected within the guide groove. One end of the elastic rope 25 is fixed to the pulley 21 on the second side beam 3 via a fastener 9, which is a screw. (The last sentence appears to be incomplete and possibly refers to a curtain fixing plate.) The screws on the 5 are threaded through the through holes on the surface of the telescopic curtain 4 and connected to the second side beam 3. Both the curtain fixing plate 5 and the second side beam 3 are provided with anti-slip grooves to prevent the ends of the telescopic curtain 4 from falling off or misaligning. After the screws are installed on the rope fixing plate 6 on the first side beam 1, the end of the elastic rope 25 will be tied in the thread groove on the surface of the screw. When the rope fixing plate 6 is fixed to the second side beam 3 by the screws, the part of the elastic rope 25 near the screw will be squeezed between the rope fixing plate 6 and the second side beam 3, which improves the firmness of the connection. In this embodiment, when the user moves the second side beam 3, the elastic rope 25 and the telescopic curtain 4 can be pulled. The pulled elastic rope 25 drives the spool 21 and the roller 22 to rotate. When the roller 22 rotates, one end of the coil spring 24 sleeved on its surface rotates with the roller 22, and the other end is fixed in the fixed shell 26. The rotation of the roller 22 forcibly twists the coil spring 24, causing the coil spring 24 to undergo elastic deformation. The pulling force applied by the user is converted into the elastic potential energy of the coil spring 24 and stored. The farther it is pulled, the tighter the coil spring 24 is twisted, and the greater the pull-back force. After the second side beam 3 is released, the elastic deformation of the coil spring 24 controls the spool 21 and the roller 22 to rotate in opposite directions. The rotating spool 21 pulls the second side beam 3 by winding the elastic rope 25. When the elastic deformation of the coil spring 24 drives the rotation speed of the spool 21 and the roller 22 to increase, the viscous resistance of the high-viscosity fluid filled inside the friction damper will increase sharply, thereby causing the telescopic curtain 4 to slowly and gently fold back, and finally the second side beam 3 enters the limiting groove 12.

[0020] Example 3: In some embodiments, such as Figure 6 As shown, in a preferred embodiment of the present invention, the adsorption unit 73 further includes a piston block 735 and a pre-tightening spring 736. A variable volume compensation cavity 737 is provided on the side of the base shell 731 away from the silicone suction cup 732. The piston block 735 is slidably connected in the variable volume compensation cavity 737. A vent hole 734 is provided between the variable volume compensation cavity 737 and the sealed adsorption cavity 733. The side of the piston block 735 away from the vent hole 734 is connected to the variable volume compensation cavity 737 through the pre-tightening spring 736. In this embodiment, at room temperature, the pre-tension spring 736 pushes the piston block 735 downward, compressing the variable volume cavity to its minimum state. Under high temperature exposure, when sunlight causes the air in the sealed adsorption cavity 733 to expand due to heat, some excess gas enters the variable volume compensation cavity 737 through the vent 734. The gas entering the variable volume compensation cavity 737 pushes the piston block 735 upward, and the pre-tension spring 736 further compresses the volume of the variable volume compensation cavity 737, thereby increasing its volume to accommodate the thermally expanded air. Throughout the process, because the excess hot gas is squeezed into the variable volume compensation cavity 737, the pressure difference between the inside and outside of the sealed adsorption cavity 733 remains relatively stable, which solves the problem of the silicone suction cup 732 easily falling off under high temperature exposure and improves the stability of the adsorption state.

[0021] Example 4: In some embodiments, such as Figures 3 to 5 As shown, in a preferred embodiment of the present invention, the rotating plate 71 has a recessed groove 711 and a slot 713 on its side. The recessed groove 711 has a mounting hole 712. The adjustable hook module 8 is installed in the mounting hole 712. The adjustable hook module 8 includes a frustum 81, a second rotating shaft 82, a limiting member 83, a hook body 84, and a third rotating shaft 85. The second rotating shaft 82 is rotatably connected in the mounting hole 712. One end of the second rotating shaft 82 is fixedly connected to the frustum 81. The end of the hook body 84 near the frustum 81 is fixedly connected to the third rotating shaft 85. The third rotating shaft 85 is rotatably connected to the surface of the frustum 81. The limiting member 83 is installed at the end of the second rotating shaft 82 away from the frustum 81. The limiting member 83 can be designed as a nut to prevent the second rotating shaft 82 from disengaging from the mounting hole 712. The nut is threadedly connected to the end of the second rotating shaft 82 away from the frustum 81. In this embodiment, the user can not only rotate the hook body 84 around the second pivot 82 as the axis to adjust the orientation of the hook body 84, but also rotate the hook body 84 around the third pivot 85 as the axis to adjust the tilt angle of the hook body 84. In the initial state, by rotating the third pivot 85, the hook body 84 can be hidden in the slot 713, which is convenient for daily carrying and storage. With the second side beam 3 pulled to unfold the telescopic curtain 4, the hook body 84 can be connected to the hook on the B-pillar of the RV, the inside of the sun visor, or a hook pre-installed in the RV interior by adjusting the orientation and tilt angle of the hook body 84 around the second pivot 82 and the third pivot 85.

[0022] A retractable sunshade method for RVs includes: S100. Manually rotate the rotating plate 71 with the first rotating shaft 72 as the axis, so that the adsorption surfaces of the silicone suction cups 732 at the first side beam 1 and the second side beam 3 are parallel to the telescopic curtain 4, and the silicone suction cups 732 at the first side beam 1 are adsorbed and fixed to one side of the windshield. Pull the second side beam 3 towards the other side to unfold the telescopic curtain 4, and the silicone suction cups 732 at the second side beam 3 are adsorbed and fixed to the other side of the windshield. S200. Manually rotate the rotating plate 71 with the first rotating shaft 72 as the axis, so that the adsorption surface of the silicone suction cup 732 at the first side beam 1 is perpendicular to the telescopic curtain 4, and adsorb it at the bottom of the windshield near the RV dashboard. Pull the second side beam 3 towards the RV sun visor to unfold the telescopic curtain 4. Manually adjust the angle of the rotating plate 71 with the first rotating shaft 72 as the axis, and adjust the orientation and tilt angle of the hook body 84 around the second rotating shaft 82 and the third rotating shaft 85. Hang the hook body 84 on the RV sun visor or in the hook pre-installed on the sun visor. S300. When it is necessary to use the sunshade assembly to shade the windows, manually rotate the rotating plate 71 with the first rotating shaft 72 as the axis, so that the adsorption surface of the silicone suction cup 732 at the first side beam 1 is perpendicular to the telescopic curtain 4, and adsorb it on the windshield near the A-pillar; when the hook is pre-installed on the A-pillar, adjust the orientation and tilt angle of the hook body 84 around the second rotating shaft 82 and the third rotating shaft 85, or hang the hook body 84 at the first side beam 1 in the hook; pull the second side beam 3 towards the B-pillar of the RV to unfold the telescopic curtain 4, manually adjust the angle of the rotating plate 71 with the first rotating shaft 72 as the axis, adjust the orientation and tilt angle of the hook body 84 around the second rotating shaft 82 and the third rotating shaft 85, and hang the hook body 84 in the hook on the B-pillar.
