Description

Technical Field

[0001] This invention relates to a roller blind assembly including a rotating wire guide for guiding a tension wire from a wire pulley at a controlled angle and guiding the tension wire onto the wire pulley. The invention also relates to a roof assembly including the roller blind assembly, and a vehicle including the roof assembly. Background Technology

[0002] Vehicles (such as passenger cars) may be equipped with a roof panel or roof panel system having one or more roof panel panels. The roof panel panels can move between a closed position and an open position, wherein the roof opening is covered or uncovered, or the roof panel panels can be fixed. In either case, one or more roof panels may be transparent to allow light into the vehicle's passenger compartment. To control the amount of light entering, the vehicle may be equipped with a roller blind assembly comprising a curtain that can move between a closed position and an open position, and any position in between (i.e., partially closed or partially open). The roller blind assembly may also be called a rollo assembly, and similarly, the curtain may be called a roller blind or roll-up curtain. The curtain is movable by being wound on or unwound from a winding tube or shaft. In the fully open position, the curtain is completely wound on the winding tube. In the closed position, the curtain is almost completely unwound from the winding tube.

[0003] In known roller blind assemblies, the blind is operated via a drive cable driven by a motor, which is connected to an operating beam of the blind via a slipper. The operating beam can also be called a pull beam because it pulls the blind, or a front beam, depending on its position relative to the front of the vehicle. The motor drives the movement of this drive cable, thereby moving the drive shoe and the connected operating beam. Therefore, pulling the operating beam away from the winding tube will disengage the blind from the winding tube, while pulling the operating beam towards the winding tube will allow the blind to wind onto the winding tube. Furthermore, the winding tube is typically equipped with a spring-like assembly to allow winding when the blind opens the top panel opening.

[0004] Alternatively, a roller blind assembly can be installed where the movement of the blind is operated by a motor that directly drives the blind's winding tube, rather than by a drive cable. To maintain the blind's tension at every possible position of the operating beam (between the fully extended and fully rolled-up blinds), a tension wire is installed between the winding tube and the operating beam. More specifically, a wire pulley is installed on the winding tube, with one end of the tension wire attached to it. The other end of the tension wire is attached to the operating beam or to a spring located inside the operating beam. During blind operation, the tension wire can be wound around or unwound from the wire pulley.

[0005] This direct-drive roller blind assembly offers improvements in noise, vibration, and acoustic roughness, as well as operational performance and cost. Furthermore, because the wire pulleys and drive motor are housed alongside the blind's winding tube, the entire assembly can be wider than conventional roller blind assemblies operated by drive cables.

[0006] Furthermore, when the entire roof panel system with a directly driven roller blind assembly also includes components such as a wind deflector mechanism, the roller blind assembly can be packaged in a separate space within the interior area of ​​the other components, resulting in a narrower daylight opening in the lateral direction of the vehicle. To maintain a wider daylight opening in the lateral direction, the roller blind assembly and other roof panel components can be packaged adjacent to each other in a combined space, resulting in a larger step in the lateral direction between the tension wire and the wire pulley. This creates a larger angle for the tension wire to roll onto the wire pulley, or requires a larger distance in the longitudinal direction of the vehicle to reduce said angle. Since the distance in the longitudinal direction is limited by vehicle dimensions, the latter is generally not an option.

[0007] A large angle between the tension wire and the wire pulley can cause numerous problems, including noise, which must be mitigated. In particular, the wire pulley is typically cylindrical or conical in shape and has a spiral winding groove. When viewed from above, the angle between the tension wire and the wire pulley becomes too large, and the tension wire may not be properly positioned within the winding groove, potentially causing a clicking sound or even worse, falling off the groove. Therefore, it is necessary to reduce or at least control the angle between the tension wire and the wire pulley. Therefore, the object of this invention is to provide a direct-drive roller blind assembly in which the angle between the tension wire and the wire pulley is reduced and / or controlled. Summary of the Invention

[0008] The object of the present invention is achieved by providing a roller blind assembly for a vehicle, wherein the roller blind assembly includes: a frame for mounting the roller blind assembly on the roof of the vehicle; at least one guide rail disposed on one side of the frame and extending in a longitudinal direction; a winding tube disposed at the rear side of the frame and extending in a transverse direction substantially perpendicular to the guide rail; a curtain, a first end of which is attached to the winding tube for winding onto and unwinding from the winding tube in a generally longitudinal direction; an operating beam attached to a second end of the curtain; and at least one wire pulley. Attached to the outer end of the winding tube; and a tension wire, the first end of which is attached to a wire pulley and the second end of which is attached to an operating beam for winding onto and unwinding from the wire pulley, wherein a rotating wire guide is disposed at the end of the guide rail closest to the winding tube, the rotating wire guide including a rotatable base portion and a guide wheel arranged on a shaft, the rotatable base portion being adaptable to the angle of the guide wheel such that the angle of the tension wire extending onto and from the wire pulley is limited within a controllable range during the winding and unwinding of the tension wire.

[0009] A frame for mounting a roller blind assembly may consist only of the roller blind assembly, such as a box including a winding tube and guide rails for guiding the blind. The frame may also include additional components such as a drive motor, a control unit for operating the roller blind assembly, a wind deflector, and / or a mechanism for holding the top panel.

[0010] The guide rails extend longitudinally to guide the blind in the longitudinal direction during operation of the roller blind assembly. Preferably, the guide rails are located on each side of the frame. The guide rails may include multiple guide channels for guiding other components besides the blind, such as tension wires. The guide rails may include inlets for the side edges of the blind to guide it into guide members.

[0011] The winding tube may include a shaft mounted on a support for rotating the winding tube. A motor may be located at the end of the winding tube or on the shaft for rotating the winding tube. The motor may be an L-shaped motor. Two motors may be provided, one at each end of the winding tube.

[0012] The first end of the curtain is attached to the winding tube so that the curtain can be rolled onto and unrolled from the winding tube. The curtain can be attached by any suitable attachment method.

[0013] The operating beam is attached to a second end of the curtain, which is opposite to the first end of the curtain attached to the winding tube. The operating beam can be a rod-shaped beam or a flat beam. The operating beam may include a spring element on its inner side. The operating beam may also be a solid beam without a spring element on its inner side.

[0014] The wire pulley can be cylindrical or conical. Preferably, the wire pulley is conical and has a spiral winding groove for winding the tension wire, so that the (unwinding) winding diameter of the tension wire on the wire pulley is always substantially equal to the (unwinding) winding diameter of the curtain on the winding tube.

[0015] The first end of the tension wire is attached to a wire pulley, and the second end is attached to the operating beam. The second end can be attached to one side of the operating beam or to a spring element located inside the operating beam. When the tension wire is attached to one side of the operating beam, and when the operating beam does not include a spring element inside, the spring assembly can be provided separately to keep the tension wire taut within the roller blind assembly. The tension wire, together with the operating beam, allows the blind to be tightened during operation of the roller blind assembly.

[0016] During operation, the tension wire winds onto and unwinds from the wire pulley following a spiral winding groove. The tension wire should be properly positioned within the winding groove without excessively crossing its flange to prevent major operational problems. When viewed from above, the tension wire should therefore form a relatively smooth angle with the wire pulley in the XY plane of the assembly. This angle varies within a certain range as the tension wire winds onto or unwinds from the wire pulley. Therefore, a rotating wire guide is provided, comprising a rotatable base portion and a guide wheel arranged on an axis. The rotatable base portion can be directly attached to or at least a portion of a frame for mounting the roller blind assembly, or attached via an intermediate base frame. The guide wheel can rotate about the axis. When the guide wheel rotates, the rotatable base portion can rotate or turn relative to the frame or the intermediate base frame to adapt to the angle of the guide wheel, thereby allowing the tension wire to be guided in different directions on the guide wheel, thus allowing the angle with the wire pulley to be limited in a controlled manner, thereby achieving the purpose of the present invention.

[0017] In one embodiment, the rotating wire guide further includes a shaft support portion for supporting the guide wheel shaft. The shaft support portion allows the shaft to be raised above the rotatable base portion. The shaft support portion can be a single shaft support or multiple shaft supports. The shaft support portion can be, for example, a single U-shaped support, wherein the shaft is positioned on the inside of the U-shape. The shaft support portion can also be, for example, two or more upright supports for holding the shaft above the rotatable base portion.

[0018] In this embodiment, the guide wheel axle and the axle support portion form an integral part. The guide wheel axle can be suitably shaped to have a generally vertical portion serving as the axle support portion and a horizontal portion for supporting the guide wheel. Such a support-shaped guide wheel axle can be shaped in such a way that the guide wheel can only move along the horizontal portion of the support-shaped axle. For example, the guide wheel axle can have a U-shaped form, wherein the transition between the horizontal and vertical portions will deform to prevent the guide wheel from transitioning from the horizontal portion to the vertical portion.

[0019] In this embodiment, two guide rails are provided, one on each side of the frame, extending longitudinally and facing each other. With the two guide rails arranged symmetrically, the blind is more securely guided within the roller blind assembly.

[0020] In this embodiment, two wire pulleys are provided, one on each side of the winding tube. Two tension wires are attached to each wire pulley, and two rotating wire guides are provided at the end portions of each guide rail. In addition to using two guide rails, this allows for more reliable operation of the roller blind assembly.

[0021] In the embodiment, the angle between the tension wire and the wire pulley in the XY plane is preferably in the range of 0° to 7° in the XY plane.

[0022] When the tension wire is viewed from above relative to the wire pulley, in the XY plane, the tension wire ideally winds around the wire pulley at a right angle. In other words, the tension wire is ideally perpendicular to the wire pulley axis, thus forming a 0° angle with the wire pulley. Due to the width of the wire pulley and the external position of the guide member that guides the tension wire, this preferred angle cannot be maintained when the tension wire is fully wound onto the wire pulley. Therefore, an angle other than 0° will be formed. To prevent the tension wire from detaching from the wire pulley, this angle is preferably at most 7° in the external position of the guide member.

[0023] In the embodiment, the angle between the tension wire and the wire pulley in the XZ plane is preferably in the range of 5° to 25° in the XZ plane.

[0024] When the tension wire is viewed from the side relative to the wire pulley, in the XZ plane, the tension wire forms a small angle from the guide member toward the wire pulley to maintain tension on the wire when it is unwound from or wound onto the wire pulley. At the same time, an angle that is too large may cause the tension wire to detach from the bottom of the wire pulley. Therefore, this angle is preferably in the range of 5° to 25°.

[0025] In one embodiment, the rotatable base portion of the rotating wire guide is directly attached to the frame for mounting the roller blind assembly.

[0026] The frame for mounting the roller blind, or at least a portion thereof, can be used to receive the rotatable base portion of the rotating wire guide. This allows for direct attachment of the rotating wire guide, thereby reducing alignment errors of the rotating wire guide within the roller blind assembly.

[0027] In one embodiment, the operating beam includes a spring element, and a tension wire is attached to the spring element.

[0028] In one embodiment, the spring assembly is located at the second end portion of the guide rail and includes a pair of guide members for guiding the tension wire. The first guide member is fixed to the spring element, and the second guide member is attached to the guide rail. The spring element is fixed to a portion of the frame. This embodiment is particularly advantageous when the operating beam does not include sufficient space for housing the spring element. Thus, the spring element can be positioned elsewhere, as shown in this particular embodiment, allowing the first guide member to move freely in the longitudinal direction and maintaining sufficient tension on the tension wire for operation.

[0029] In one embodiment, the first guide member and the spring element are disposed in a guide channel of the frame, which is suitable for guiding the windshield mechanism.

[0030] In an aspect of the invention, a roof panel assembly for a vehicle is provided, comprising a roller blind assembly as shown above, wherein the roof panel assembly further comprises a roof panel panel that is at least partially transparent. The roof panel panel can be any type of roof panel panel suitable for allowing light to pass through it. The roof panel panel can be, for example, a glass panel or a plastic panel.

[0031] In this embodiment, the roof panel is a fixed glass panel. An example of such a roof panel is a panoramic glass roof.

[0032] In this embodiment, the top panel is a movable glass panel. An example of such a top panel is a skylight.

[0033] In another aspect of the invention, a vehicle is provided that includes a roof assembly as described above.

[0044] In the following description, spatial references (e.g., front, side, and rear; or lower, bottom, and top; or forward and backward directions, and driving motion) are made relative to the overall orientation of the vehicle (e.g., a passenger car), and particularly relative to, for example, the driver behind the steering wheel. Furthermore, the X, Y, and Z directions will refer to the directions corresponding to the length, width, and height of the vehicle, or the longitudinal, lateral, and vertical directions, respectively. In the accompanying drawings, the forward driving motion of the vehicle may be indicated, for example, by arrow D1, which points towards the front of the vehicle.

[0045] Figure 1AThis diagram illustrates a vehicle roof panel according to the prior art, having an opening roof panel assembly 1 disposed therein. The opening roof panel assembly 1 includes a movable panel 2a and a fixed panel 2b. The movable panel 2a is also referred to as a closing component because it is movable over a first roof panel opening 3a, enabling it to open and close. A wind deflector 5 is disposed in front of the first roof panel opening 3a, comprising a flexible material, such as a woven or non-woven fabric with through-holes, or a mesh or wire mesh supported by a support structure 5a (e.g., a strip or tubular structure), which is directly or indirectly hinged to a frame at a hinge 5b. A roller blind assembly 4 is located below the vehicle roof panel, having a curtain movable between a closed and open position, also referred to as a sunshade or sunshade. This allows control over the amount of sunlight exposed to the interior through the roof panel opening 3a (or, in the case of a transparent panel 2a).

[0046] exist Figure 1B The text provides a more detailed explanation. Figure 1A Roller blind assembly 4. Roller blind assembly 4 is shown in an assembled state. As shown, the roller blind assembly can be used as a sunshade or shading curtain assembly and can be positioned below the movable top panel 2a, or for example, below the movable top panel 2a and the fixed top panel 2b.

[0047] The roller blind assembly 4 includes a blind 21 and a winding tube 22 rotatable about a fixed axis of rotation 23. The blind 21 extends substantially along a first direction D1 and is connected to an operating beam 24. Along the opposite second direction D2, the blind is connected to the winding tube 22. The blind 4 can be unwound from and wound around the winding tube 22. The winding tube 22 is provided with wire pulleys 25, 25' at opposite outer ends, which rotate concentrically with the winding tube 22 about the axis 23.

[0048] For mounting on the respective outer ends of the winding tube 22, each wire pulley 25, 25' may have a tube support. At least one wire pulley 25, 25' has a cavity in which the output shaft of the gearbox 26 can be disposed. The inner surface of the cavity corresponds to the outer surface of the shaft to provide a form-locking connection. Alternatively, there may be wire pulleys with shafts and gearboxes with corresponding cavities. The motor 27 is configured to drive the rotation of the winding tube 22 via the gearbox 26.

[0049] The roller blind assembly 4 also includes two parallel roller blind guides 28, two reverse pulleys 29, and two tension wires 30, 30'. Each tension wire 30, 30' extends from a wire pulley 25, 25' around a reverse pulley 29, 29' toward the operating beam 24. Furthermore, the reverse pulleys 29, 29' are rotatably attached to their respective guides 28, 28'. Each tension wire 30, 30' is attached to a respective wire pulley 25, 25' via a first end, allowing it to wind onto and unwind from the wire pulleys 25, 25'. The tension wires 30, 30' are guided through the parallel guides 28, or may at least extend through the parallel guides 28. Each wire pulley 25, 25' attached to the first end of the corresponding tension wire 30, 30' is also equipped with a spiral groove, allowing the tension wire 30, 30' to be wound onto and unwound from the wire pulley 25, 25' in a controlled manner. The groove is provided on the inclined portion of the wire pulley 25, 25' and extends spirally on the outer surface of the pulley. The tension wire 30, 30' is attached to the operating beam 24.

[0050] Figure 1C This indicates that, according to the existing technology Figure 1B An enlarged view of the wire pulley section 10 of the roller blind assembly 4. The tension wire 30 can be seen more clearly relative to the wire pulley 25 and the roller blind guide 28. It can be seen that the guide wheel 31 is configured to guide the tension wire 30. Figure 1D In the diagram, the wire pulley portion 10 is visible from above, thus simultaneously representing the first external position of the tension wire 30' and the guide wheel 31' and the second external position of the tension wire 30'' and the guide wheel 31'' in the XY plane. Dashed lines distinguish these positions, and these lines are arranged perpendicular to the axis of the wire pulley 25. The tension wires 30' and 30'' form an angle with respect to the dashed lines.

[0051] exist Figure 2A The diagram illustrates an example wire pulley portion 10 of a roller blind assembly 4 according to the invention. The wire pulley portion 10 of the roller blind assembly 4 includes a rotating wire guide 33 attached to the end of a guide rail 28. The rotating wire guide 33 includes a rotatable base portion 34, a shaft support portion 35, a shaft 32 disposed within the shaft support portion 35, and a guide wheel 31 disposed on the shaft 32. The guide wheel 31 moves freely along the shaft 32, while the rotatable base portion 34 can rotate or turn to accommodate the shaft and guide wheel 31, such that the tension wire 30 forms an angle of up to 7° between the guide wheel 31 and the wire pulley 25 at any position of the guide wheel 31. Therefore, the base portion allows the guide wheel to adapt to the angle of the tension wire by rotating to align the shaft and guide wheel with the tension wire.

[0052] Figure 2B This diagram shows a perspective view of the rotating wire guide 33, where a rotatable base portion 34 is located on a frame portion 36. Two shaft support portions 35a and 35b are disposed on the rotatable base portion 34, and a shaft 32 is disposed between the two shaft support portions 35a and 35b. A guide wheel 31 is disposed on the shaft 32. In use, the rotatable base portion 34 can rotate or turn as indicated by arrow S.

[0053] Alternatively, a single shaft support portion 35 can be implemented by, for example, an arched U-shaped support spanning the guide wheel 31 and the shaft 32. In another alternative, the shaft 32 can float at one end while being attached to the upright shaft support portion 35 at the other end. In yet another alternative, the shaft 32 can be suitably shaped to serve as both the shaft 32 and the shaft support portion 35. For example, the support-shaped shaft 32 can have a vertical portion serving as the support 35 and a horizontal portion for supporting the guide wheel 31. The support can be shaped such that the guide wheel 31 can only move along the horizontal portion of the support-shaped shaft 32.

[0054] exist Figure 3A The image illustrates an example spring assembly 40 of a roller blind assembly 4 according to an embodiment of the present invention. The spring assembly 40 is disposed at a second end portion of a guide rail 28 and includes a pair of guide members 41a and 41b for guiding the tension wire 30. The first guide member 41a is fixed to a spring element 42. The spring element 42 is preferably fixed to a portion of the frame of the roller blind assembly 4. The second guide member 41b is attached to a portion of the guide rail 28. The first guide member 41a is freely movable in the longitudinal direction, thereby allowing the spring element 42 to expand or contract while maintaining tension on the tension wire 30.

[0055] Figure 3B An example top plate assembly 4 is shown, which includes a pair of wire pulley portions 10, 10' and a pair of spring assemblies 40, 40', as shown. Figure 3A As shown. The wire pulley portions 10 and 10' can be conventional wire pulley portions or wire pulley portions according to any of the embodiments disclosed above.
