Description

Technical Field

[0001] The present invention relates to a device for regulating airflow in the front module of a motor vehicle and a motor vehicle including such a device. Background Technology

[0002] In modern motor vehicles, fresh air flowing in through the radiator grille or its openings is guided and delivered to the vehicle's cooling module. In particular, by specifically directing the airflow to the cooling module, it is ensured that, corresponding to the design of the cooling module, the vehicle engine and / or the engine's pressurized air and / or the vehicle's interior can be effectively cooled, for example, efficiently cooled.

[0003] The downside is that the inflowing airflow generates turbulence, which can impede the movement of the vehicle and lead to reduced mileage and increased fuel consumption. To address this issue, existing technology has developed a roller shutter system that can close the air intake located in the engine compartment as needed, thereby reducing turbulence.

[0004] However, in this case, the airflow control systems known from the prior art for motor vehicle front-end modules typically have the following problem: it is difficult to ensure a constant material tension in the sealing components. This results in the air intakes located in the engine compartment not closing properly in certain areas, and therefore turbulence generation cannot be sufficiently reduced. The reasons for insufficiently constant material tension are generally specific tolerances of the components, the diameter difference during the winding and unfolding of the roller shutter system, and especially the wear phenomena of individual components. Summary of the Invention

[0005] Therefore, the object of the present invention is to at least partially eliminate the aforementioned disadvantages of known devices for regulating airflow in the front-end module of a motor vehicle. In particular, the object of the present invention is to provide a device for regulating airflow in the front-end module of a motor vehicle that allows for as effective and reliable turbulence reduction as possible in a simple and low-cost manner, while being particularly flexible and adjustable in design.

[0006] The aforementioned task is accomplished by a device having the features of the independent device claim and a motor vehicle including such a device. Other features and details of the invention are derived from the corresponding dependent claims, description, and figures.

[0007] According to the present invention, an apparatus for regulating airflow in a vehicle front-end module is provided, comprising: a sealing member for closing an air inlet of the vehicle front-end module; a guide member for guiding the sealing member during opening and closing movements; a first control member and a second control member for controlling the opening and closing movements of the sealing member; and a first drive member and a second drive member for driving the opening and closing movements of the sealing member. According to the present invention, the airflow regulating apparatus is characterized in that the first and second control members have a multi-piece integrated tensioning and tolerance compensation mechanism for compensating for the variable preload of the first and second drive members to ensure a substantially constant tension in the sealing member.

[0008] The device of the present invention for regulating airflow in the front module of a motor vehicle is preferably arranged in the front region of the vehicle, particularly between the radiator grille or front hood and the vehicle's cooling module. Besides use in passenger cars and trucks, the device of the present invention can also be used in other motor vehicles such as ships or aircraft. The opening and closing processes of the closure are preferably achieved through the interaction between the control element, drive element, and guide element of the present invention, so as to close or open the air intake arranged along the height of the vehicle. Such an air intake can be formed, for example, in the form of a brake air duct or air supply duct for an engine compartment or for an air conditioning system.

[0009] According to the invention, the guide member is preferably arranged between the first and second control members, particularly directly between the first and second control members. Within the scope of the invention, the open position specifically refers to a state where the closure is fully wound around the guide member and air can enter the front-end module almost unimpeded. Within the scope of the invention, the closed position specifically refers to a state where the closure is fully unfolded from the guide member and at least partially, preferably completely, locks the airflow path. Within the scope of the invention, the substantially constant tension of the closure specifically refers to the substantially constant pulling force acting on the closure, which particularly results in substantially constant and as optimal aerodynamic characteristics as possible, while also minimizing turbulence as effectively as possible. Constant pretension in this case is extremely important for preventing the closure from "fluttering" and forming creases in the traveling airflow, and thus ensuring proper winding. Within the scope of the invention, a multi-piece assembly specifically refers to an assembly consisting of multiple individually manufactured parts that can be interconnected by form fit, force fit, or material bonding.

[0010] It has been recognized within the scope of this invention that the arrangement of the tensioning and tolerance compensation mechanism of this invention can compensate for the variable preload of the drive mechanism, thereby ensuring a substantially constant tension acting on the closure component of this invention even under different environmental and system conditions. In particular, due to the multi-piece design of this invention, wear adjustments to the components of the device can be made in a simple and rapid manner, thereby improving the sustainability of the system of this invention for regulating airflow.

[0011] Within the scope of simple structural design and effective force transmission, the present invention can particularly specify that the first and second control members have receiving mechanisms located at their ends, which have receiving areas for receiving the drive member, wherein the receiving mechanisms preferably have the same design. In this case, the drive member can preferably be guided or slid through the receiving area of ​​the receiving mechanism while ensuring the lowest possible static friction.

[0012] To ensure the connection between the control element and the guide element is as simple, flexible and adjustable as possible, it is conceivable that the control element has a connecting mechanism for connecting the receiving mechanism to the guide element, wherein the connecting mechanism is preferably able to be connected to the guide element in a form-fit manner, and wherein the connecting mechanisms are at least partially different from each other in terms of their shape.

[0013] Within the scope of a simple structural design, the present invention may also specify that the tensioning and tolerance compensation mechanism is connected to the drive member, preferably engaged with the drive member.

[0014] Regarding a simple, low-cost, and adjustable possible method for compensating for variable preload, the present invention may also advantageously specify that the tensioning and tolerance compensation mechanism has at least one elastic element for compensating for variable preload, wherein the elastic element is preferably formed in the form of a spring, particularly a torsion spring.

[0015] In this case, within the scope of the invention, it is advantageous to conceive of a spring force of 28N to 22N, preferably between 26N and 24N, and especially 25N.

[0016] Within the scope of possible structurally simple methods that ensure the elastic element can be detachably fixed within the control element of the invention, the invention can particularly advantageously specify that the tensioning and tolerance compensation mechanism has at least one front retaining point and a rear retaining point for fixing the front and rear ends of the elastic element, wherein the retaining points are preferably formed in the form of recesses and / or protrusions.

[0017] In this case, it is advantageous to imagine that the front holding point is arranged within the receiving mechanism, wherein the front holding point is preferably formed in the form of an elongated recess for introducing the front of the elastic member.

[0018] It is also conceivable that the rear retaining point is arranged within the connecting mechanism, wherein the rear retaining point is preferably formed in the form of an elongated recess for introducing the rear of the elastic member.

[0019] To ensure compensation for wear on the components of the airflow regulating device of the present invention in a particularly simple manner, the present invention may also specify the provision of multiple front and / or rear holding points to ensure the adjustment of different spring preload forces, wherein the front and / or rear holding points are preferably symmetrically distributed, particularly arranged symmetrically along the cross-section of the receiving mechanism and / or connecting mechanism. In this case, the holding points can be particularly formed in the form of an adjusting mechanism for compensating for wear.

[0020] In order to minimize wear on the components of the airflow regulating device, especially the elastic element, it is conceivable that the receiving mechanism and / or connecting mechanism have a limiting mechanism for restricting the working area of ​​the elastic element, wherein the limiting mechanism preferably has an end stop surface for restricting the working area, which is formed in particular in the form of a recess and a corresponding protrusion.

[0021] To ensure that the closure has a substantially constant tension even in different open and closed states, and thus prevent the possibility of incomplete closure of the air inlet, the present invention may also specify that the first and second control elements are formed such that the increase or decrease in the diameter of the guide element caused by the winding and unfolding of the closure element is compensated to minimize the difference in roll width speed when the closure element is wound and the drive element is unfolded, and when the drive element is wound and the closure element is unfolded.

[0022] Advantageously, within a range where the increase or decrease in diameter caused by the winding and unwinding of the closure is compensated, the first and second control members can have varying diameters to compensate for the increase or decrease in the diameter of the guide member caused by the winding and unwinding of the closure. The first and second control members preferably have a barrel geometry or a truncated conical geometry. The barrel geometry here exhibits at least a partially parabolic cross-section, while the truncated conical geometry has a linear slope in the cross-section.

[0023] To ensure precise and controllable guidance of the drive element, it is particularly conceivable in embodiments with control elements having varying diameters that the first and second control elements have a winding helix for accommodating the drive element, wherein the winding helix preferably has a constant pitch.

[0024] Alternatively, within the range of compensating for the diameter increase or decrease caused by the winding and unwinding of the closure, the first and second control members can be optionally specified to have constant diameters, wherein the first and second control members preferably have cylindrical geometries. To ensure precise and controllable guidance of the drive member, in embodiments with constant control member diameters, it is particularly conceivable that the first and second control members have winding helices for accommodating the drive member, wherein the winding helices have variable pitches for compensating for the diameter increase or decrease of the guide member caused by the winding and unwinding of the closure. By adjusting the shape and geometry of the control members, the geometry most suitable for the respective installation conditions can be used for the winding area of ​​the pulling material. Here, the geometry may depend on various factors such as available structural space or additional components.

[0025] To ensure minimal wear on the drive component and flexible design, the present invention may further specify the provision of a first deflector and a second deflector for deflecting the drive component, wherein the deflector is preferably formed in the form of a deflecting roller.

[0026] To achieve a stable arrangement of the various components and reliable control of the closure element of the present invention, the present invention may further specify the provision of a frame for accommodating the deflector, wherein the frame preferably has two side frame portions for guiding the deflector and a lower frame portion for arranging the end strip. In this case, the side frame portions are preferably detachably connected, particularly in a form-fit or force-fit manner, to or connected to the lower frame portion.

[0027] Regarding the simple and compact arrangement and the precise and effective control of the closure during both opening and closing movements, within the scope of the invention, it can also be specified that the frame is further provided for supporting the closure, wherein the frame preferably has a grid structure for supporting the closure.

[0028] To provide a simple, reliable, and low-cost method for the detachable fixation of the closure within the airflow regulating device of the present invention, the present invention particularly specifies that the frame and / or guide are connected to the closure in a form-fit and / or force-fit manner, wherein the closure is preferably detachably connected to the frame and / or guide by a clamping connection. In the clamping case using the clamping connection, the closure is preferably fixed by generating increased frictional force.

[0029] Regarding the separable connection between the closure and the airflow regulating device of the present invention, which can be structurally simple to produce, it is particularly conceivable to provide a mounting for connecting the frame and / or guide to the closure, wherein the mounting preferably has at least one slit-like recess for introducing the closure, and in particular at least two slit-like recesses.

[0030] In this case, the mounting component can be designed as a multi-piece unit, preferably having at least three parts.

[0031] In cases where a simple and reliable fixation is desired, it is advantageous to specify that the frame and / or guide has a recess arranged on the longitudinal side for introducing the closure and mounting member, wherein the recess is preferably designed so that the closure, when arranged in the recess, is securely fixed to the frame and / or guide member together with the mounting member in the direction of force applied to the closure in the closure. To secure the closure to the frame and / or guide member, the closure can then be moved, for example, through one or more slit-shaped recesses of the mounting member and positioned, and subsequently the mounting member, together with the inserted portion of the closure, is laterally inserted into the longitudinally located recess of the frame and / or guide member, such that the closure is securely fixed to the frame and / or guide member in the direction of force applied to the closure in the closure. In this case, the closure can also be pushed through two gaps for secure fixation, and in the case of a multi-piece design of the mounting member, it can be guided, for example, through both sides of each part of the mounting member to transmit greater force.

[0032] In this case, within the range of simultaneously stable and easily manufactured fixation, it is conceivable that the recess is designed as a wedge shape and the mounting member is at least partially designed to correspond in shape to the wedge-shaped recess to prevent the closure member from being pulled out in the direction of force applied to the closure member. In this case, the mounting member can preferably also be designed as a wedge shape in at least part, so that it can be fixed in the recess in a form-fit manner. For example, in the case of a multi-piece design, only a single part may be designed as a wedge shape.

[0033] In this context, it is particularly conceivable that the mounting component is a three-piece assembly, comprising a first cuboid portion and second and third portions designed at least partially to correspond in shape to the recess. These portions are preferably designed and arranged within the recess such that the arrangement of the second and third portions forms a gap for the closure to pass through, the gap diameter being smaller than the diameter of the first cuboid portion. This prevents the closure from being pulled out in the direction of force when the cuboid portion is surrounded by the closure and when the surrounded cuboid portion is placed in the recess.

[0034] Within the scope of particularly reliable fixation of the closure, it can be specifically stipulated that the mounting member has a recess for insertion of a portion of the closure, wherein the recess preferably has a clamping mechanism for securing the closure within the recess. In this way, the closure can, for example, be fixed in the mounting member and wound around the mounting member once or multiple times for reliable fixation, and subsequently, the portion of the closure wound together with the closure is preferably laterally pushed into the recess of the frame or guide. In this case, the recess can be designed as a wedge or a cuboid shape, wherein, when designed as a cuboid, the recess can have a locking protrusion for preventing the portion of the closure connected to the mounting member from dislodging in the direction of force.

[0035] To ensure that the drive mechanism of the closure is designed to be both flexible and structurally easy to integrate, the invention can also advantageously specify that the first and second drive components are designed as cables, particularly Bowden cables. In this case, especially regarding the particularly robust and durable design of the device of the invention, a drive component design in the form of a Bowden cable is recommended.

[0036] Regarding the space-saving compact arrangement and the efficient and low-wear guidance of the closure during both opening and closing movements, it can be advantageously specified within the scope of the invention that the guide is formed in the form of a winding shaft, on which the closure can be wound during the opening movement and unfolded from the winding shaft during the closing movement.

[0037] In cases of simple and low-cost manufacturing, particularly for mass production, the present invention can also specify that the guide member is formed in the form of an extruded profile, preferably an extruded hollow profile. In this case, complex hollow profile structures can be manufactured in a single process using common extrusion processes.

[0038] To ensure a simple, compact, and material-saving connection between the guide and the control element of the present invention, it is particularly advantageous that the guide has two recesses arranged on the outer side for receiving the control element. These recesses can be pre-formed into the guide in the form of an extruded profile, or they can be created through additional processing of the guide.

[0039] Furthermore, within the range of particularly simple connection types between the guide and the control, it can be specified that the shape of the recess arranged on the outside is designed to correspond to the shape of the control.

[0040] A particularly lightweight design for the device of the present invention can also be specified, wherein the guide element is made of a material with a density of less than 3 g / cm³. 3 Lightweight structural materials are formed, wherein the lightweight structural materials are in particular aluminum and / or plastics.

[0041] Regarding the guidance and control of the closure in a structurally simple manner via two control elements, the invention may also advantageously specify that the guide element is arranged between the first and second control elements such that the main alignment direction of the guide element is oriented substantially perpendicular to the opening and closing movement of the closure element.

[0042] Regarding the simple and compact arrangement and the precise and effective control of the closure during both opening and closing movements, within the scope of the invention, it may also be specified that the control member is connected to the closure member via a drive member, wherein the connection is preferably designed such that the drive member is wound around the control member during the opening movement and unfolded by the control member during the closing movement.

[0043] To enable remote-controlled opening and closing of the closure, it is also advantageous to provide a drive mechanism for driving the closure. In this case, the drive mechanism is preferably designed as an actuator, especially a rotary actuator.

[0044] In addition, the subject of this invention is also a front-end module for a motor vehicle, which includes the means for regulating airflow for the front-end module as described above.

[0045] In addition, the subject of this invention is also a motor vehicle, which includes means for regulating the airflow of a front-end module, particularly including the aforementioned front-end module for a motor vehicle. Attached Figure Description

[0064] Figure 1A schematic diagram of a front-end module 1 of a motor vehicle is shown, which includes a device 2 according to the invention for adjusting the airflow of the front-end module 1, wherein the device 2 adjusts the airflow by closing the air inlet 38 of the front-end module 1.

[0065] Figure 2 The diagram shows an exploded view of the device 2 for regulating airflow in a vehicle front-end module 1 according to the first embodiment of the present invention. In this case, the device 2 includes a closure 4 for closing the air inlet 38 of the vehicle front-end module, a guide 6 for guiding the closure 4 during its opening and closing movements, first and second control members 8a and 8b for controlling the opening and closing movements of the closure 4, and first and second drive members 10a and 10b for driving the opening and closing movements of the closure 4. Here, the first and second control members 8a and 8b have a multi-piece integrated tensioning and tolerance compensation mechanism 12 (not shown here) for compensating for the variable preload of the first and second drive members 10a and 10b to ensure a substantially constant tension in the closure 4.

[0066] In this case, the guide 6 of the present invention can be particularly configured as a winding shaft, on which the closure 4, preferably made of tear-resistant fabric, is wound during the opening movement, and which is unwound from the winding shaft during the closing movement. In this case, the guide 6 is arranged between the first and second controls 8a, 8b such that the main alignment axis X of the guide 6 is oriented substantially perpendicular to the opening and closing movements of the closure 4.

[0067] The first and second drive members 10a and 10b are specifically designed in the form of cables, specifically Bowden cables, by which the closure 4 can be wound and unwound.

[0068] According to this embodiment, the control members 8a and 8b are preferably connected to the closing member 4 via the drive members 10a and 10b, so that the drive members 10a and 10b are wound around the control members 8a and 8b during the opening movement and unfolded by the control members 8a and 8b during the closing movement.

[0069] The device 2 also includes a frame 30 for accommodating the deflector 20, wherein the frame 30 has two side frame portions 31 for guiding the drive members 10a and 10b and a lower frame portion 32 for accommodating the end bar 34.

[0070] Figure 3 A schematic diagram of the present invention, in a closed form, for regulating the airflow of the front module 1 of a motor vehicle, is shown according to a first embodiment.

[0071] and Figure 2 The diagram shown is the opposite, and can be seen from... Figure 3In particular, the winding spiral 13 used to deploy the drive members 10a and 10b is seen, which is part of the first control member and the second control member 8a and 8b.

[0072] Figure 4 Show Figure 3 An enlarged schematic diagram of a portion of the device 2 shown, in which the winding spiral 13 of the second drive member 8b can be seen in more detail.

[0073] Figure 5 A schematic diagram of the guide member 6 for guiding the closure member 4 according to the invention according to the first embodiment is shown in a perspective view (top) and a cross-sectional view along the longitudinal direction (bottom).

[0074] Especially from Figure 5 The first and second control members 8a and 8b are seen to have receiving mechanisms 14 located on the end sides, which have receiving areas 14' for receiving drive members 10a and 10b, and the receiving mechanisms have the same design as each other in the present case.

[0075] Figure 6 A schematic diagram of the control element 8b according to the first embodiment of the invention is shown in an assembled state (top) and a disassembled state (bottom).

[0076] As can be seen from the disassembled state shown in the figure below, the control member 8b of the present invention has a receiving mechanism 14 located on the end side and having a receiving area 14' for accommodating the drive members 10a and 10b, a connecting mechanism 16b for connecting the receiving mechanism 14 to the guide mechanism 6, and a tensioning and tolerance compensation mechanism 12 arranged between the receiving mechanism 14 and the connecting mechanism 16b. The tensioning and tolerance compensation mechanism has an elastic member 18 and a front holding point 7 and a rear holding point 9 for fixing the front end and rear end 18a and 18b of the elastic member 18. The front holding point 7 is arranged in the receiving mechanism 14 and is formed in the form of an elongated recess for introducing the front end 18a of the elastic member 18, while the rear holding point 9 is arranged in the connecting mechanism 16b and is formed in the form of an elongated recess for inserting the rear end 18b of the elastic member 18.

[0077] The receiving mechanism 14 also has two additional front retaining points 7 to ensure different spring preloads, and these front retaining points 7 are arranged symmetrically to each other in the current case. Furthermore, from... Figure 6 As can be seen, the connecting mechanism 16b has a limiting mechanism 17 for insertion into the limiting mechanism 17 disposed within the receiving mechanism 14, thereby limiting the working area of ​​the elastic member 18. For example, the limiting mechanism 17 of the connecting mechanism 16b may be configured as a protrusion in this case, while the limiting mechanism of the receiving mechanism may be designed as a corresponding recess. Finally, the bearing 19 can be seen, through which the connecting mechanism 16b can be connected to the guide member 6.

[0078] Figure 7 A schematic diagram of the control member 8b according to the invention, together with the guide member 6 according to the invention, in an assembled state (upper) and a disassembled state (lower) according to the first embodiment.

[0079] According to Figure 7 As can be seen, the second control element 8b can be connected to the guide element 6 by means of the bearing 19 via an extruded profile placed inside the guide element 6.

[0080] Figure 8 A schematic diagram of the control element 8b according to the invention is shown in a top view of the winding shaft according to the first embodiment.

[0081] If possible Figure 8 As can be seen, the front holding points 7 set in the receiving mechanism 14 are arranged symmetrically (in a triangular plane) to each other in the current case, so that the front part 18a of the elastic element 18 can also be arranged at different holding points 7 to generate different spring preload forces.

[0082] Figure 9 A schematic diagram of a first control member 8a with a variable diameter according to a first embodiment is shown.

[0083] If based on Figure 9 As can be seen, the first control member 8a here has a barrel geometry for winding the first drive member 10a, which is particularly used to compensate for the increase or decrease in the diameter of the guide member 6 caused by the winding and unfolding of the closure member 4.

[0084] Figure 10 A schematic diagram of a first control member 8a with a variable diameter according to a second embodiment is shown. According to this second embodiment, the first control member 8a has a truncated conical geometry to compensate for the increase or decrease in the diameter of the guide member 6 caused by the winding and unfolding of the closure member 4.

[0085] Figure 11 A cross-sectional schematic diagram is shown according to Figure 9 control components ( Figure 11 a) and according to Figure 10 control components ( Figure 11 b).

[0086] according to Figure 11 a can be seen from this, according to Figure 9 The barrel-shaped geometry has a parabolic cross-section about the extension axis 11 of the guide member 6, and according to Figure 10 The truncated conical geometry has a linear slope about the extension axis 11 of the guide 6.

[0087] Figure 12 A schematic diagram of a first control member 8a having a constant diameter according to a first embodiment is shown.

[0088] according to Figure 12 The first control element 8a is shown here in a cylindrical geometry, and is consistent with... Figure 9 and Figure 10 Unlike other embodiments, instead of showing a constant pitch for the winding spiral 13, a variable pitch for the winding spiral 13 is shown to compensate for the increase or decrease in the diameter of the guide 6 caused by the winding and unwinding of the closure 4.

[0089] Figure 13 A schematic cross-sectional view showing a possible manner in which the shape of the closure 4 is fixed according to the first embodiment.

[0090] according to Figure 13 In the possible configuration shown, the closure 4 is secured within the lower frame portion 32 of the frame 30 by a three-piece mounting member 44. For this purpose, before the mounting member 44, together with the insertion portion of the closure 4, is laterally inserted into the longitudinally located recess 46 of the lower frame portion 32, the closure 4 is inserted into the first and second slit-shaped recesses 48 of the multi-piece mounting member 44, thereby securing the closure 4 to the frame 30 in the force direction B of the closure 4 to prevent loss. In the present invention, the recess 46 is designed as a wedge, and the mounting member 44 is shaped to correspond to the wedge design to prevent the closure 4 from being pulled out in the force direction B of the closure 4.

[0091] Figure 14 A cross-sectional view showing a possible manner in which the shape of the closure 4 is fixed according to the second embodiment.

[0092] and Figure 13 Unlike the first variant embodiment shown, in Figure 14 In the view, the closure 4 is guided through the first and second parts of the three-piece mounting 44 to transmit greater force.

[0093] Figure 15 A cross-sectional view showing a possible manner in which the shape of the closure is fixed according to the third embodiment.

[0094] According to the third embodiment, the mounting member 44 is also formed in three parts, wherein it has a first cuboid portion 44a and second and third portions 44b designed to at least partially correspond in shape to the recess 46 of the lower frame portion 32, wherein the portions 44a and 44b are designed relative to each other and arranged in the recess 46 such that the arrangement of the second and third portions 44b forms a gap 48 for the closure member 4 to pass through, the diameter of which is smaller than the diameter of the first cuboid portion 44a, thereby preventing the closure member 4 from being pulled out along the force direction B of the closure member 4 when the cuboid portion 44a is surrounded by the closure member 4 and when the surrounding cuboid portion 44 is placed in the recess 46.

[0095] Figure 16 A schematic cross-sectional view showing a possible manner in which the shape of the closure 4 is fixed according to the fourth embodiment.

[0096] According to the fourth embodiment, the mounting member 44 has a recess 50 for inserting a portion of the closure member 4. The recess 50 may also include, for example, a clamping mechanism not shown here. Within the scope of this embodiment, the closure member 4 may be wound around the mounting member 44 once or multiple times for reliable fixation, and then the portion of the closure member 4 wound together with the mounting member 44 is laterally pushed into the recess 46 of the lower frame portion 32.
