Description

[0001] The present invention relates to a braking device for braking the movement of at least one movable element relative to a housing, preferably relative to the housing of an air outlet. The present invention also relates to a device having such a braking device, preferably an air outlet.

[0002] Air outlets in a vehicle are generally used for ventilating the interior space of the vehicle. For this purpose, the air outlets are arranged, for example, in the dashboard area of the vehicle, and the air flow flowing through the air channel is directed along the direction of the interior space of the vehicle. In order to deflect, throttle or completely interrupt the air flow, elements for guiding and / or restricting the air flow (also referred to as plates in the following description for simplicity) are arranged in the air channel. The elements for guiding and / or restricting the air flow can generally rotate about a pivot axis, and by rotating the element for guiding and / or restricting the air flow about its pivot axis, the direction of the outflowing air can be adjusted.

[0003] In order not to cause an undesired self-adjustment of the element for guiding and / or restricting the air flow, a minimum force required for adjusting the element for guiding and / or restricting the air flow needs to be preset.

[0004] Here, the force adjustment can be carried out, for example, by means of elastic elements (such as coupling rods), which tension the element for guiding and / or restricting the air flow in its axial direction.

[0005] However, in this embodiment, there is a problem that the coupling rods are usually made of plastic. These coupling rods made of plastic relax over time, thereby reducing the frictional force for force adjustment. Therefore, the moving force also decreases over time.

[0006] In addition, for aesthetic reasons, some outlets only have a small number of, preferably only one, horizontally arranged plate. In this case, due to the reduction in the number of friction surfaces preferably arranged at the end faces on the plate support, the operating force generated by the metal coupling rods is no longer sufficient. Also, in this case, it is disadvantageous that a (sufficiently) high braking torque cannot be obtained due to the small friction diameter. Here, it is also not possible to increase the friction by means of a greater surface pressure as a countermeasure, because such a surface pressure may cause uncontrollable wear of the friction surfaces.

[0007] Another possibility for preventing the plate from self-adjusting is to generate frictional force at the support position of the plate.

[0008] However, in the described embodiments, it is disadvantageous that, in such a configuration, in order to generate frictional or motive forces, an increasing number of bearing positions must be used simultaneously. As a result, a combination of frictional forces in the radial and axial directions is generated, and thus it is generally difficult to determine how much frictional force a particular bearing position actually contributes to the overall system.

[0009] Therefore, adjusting the force to a predetermined level involves multiple repetitive steps and, therefore, it is almost impossible to correctly predict the adjustment to a specific force level. In addition, in this case, relaxation effects and wear phenomena also occur and it becomes difficult to stably maintain the force level.

[0010] Using a brake element made of silicone in an especially long tolerance chain (where the brake element is also used to compensate for tolerances) causes problems. Therefore, a brake element made of silicone has a steep elastic deformation curve, and only a small tolerance compensation can be achieved with the aid of this elastic deformation curve.

[0011] Based on the described prior art, the object of the present invention is to provide a braking device for braking the movement of a movable element relative to a housing, which braking device overcomes the above-mentioned problems and disadvantages of the prior art. In particular, the object of the present invention is to provide a braking device that allows for compensation of tolerances in the system, enables a defined adjustment of the motive force at a defined position, and allows for a simple correction of the force adjustment.

[0012] In addition, the object of the present invention is to provide a device for a vehicle, preferably an air outlet, which device or air outlet also overcomes the above-mentioned problems and disadvantages of the prior art.

[0013] The solution according to the present invention is to provide a braking device for braking the movement of at least one movable element relative to a housing, preferably relative to the housing of an air outlet, wherein the movable element is an element for guiding and / or restricting an air flow and / or an actuating element, and wherein the braking device has at least one elastic element, characterized in that the elastic element has a main extension direction which is at least substantially perpendicular to the movement path of the at least one movable element.

[0014] The movement path or movement curve is understood to be the path along which the movable element moves. In this case, in the installed state, the main extension direction of the elastic element is always (i.e., along the entire movement path) at least substantially perpendicular to the movement path. More precisely, the main extension direction is always at least substantially perpendicular to the point on the movement path where the movable element is currently located.

[0015] Another solution according to the invention consists in providing a braking device for braking the movement of at least one movable element relative to a housing, preferably relative to the housing of an air outlet, wherein the movable element is an element for guiding and / or restricting an air flow and / or an actuating element, and wherein the braking device has at least one elastic element, characterized in that the elastic element is arranged so far away from the support position of the at least one movable element, preferably the pivot axis, that the elastic element brakes the movement in a region arranged away from the support position, preferably the pivot axis.

[0016] The movement of the movable element can involve a rotational movement about a pivot axis. Alternatively, a movement along an arbitrary curve can also be achieved. The frictional force generated during the movement causes the elastic element to be loaded transversely to the main extension direction of the spring.

[0017] The main extension direction of the elastic element is the following extension direction of the elastic element: the elastic element is the longest in this extension direction. The term "at least substantially perpendicular" is also understood to mean such a direction: the deviation of this direction from the exactly perpendicular to the movement path is at most 5 degrees.

[0018] The movable element can be an element for guiding and / or restricting an air flow. The element for guiding and / or restricting an air flow is generally a plate (preferably an H-shaped plate) of an air outlet. A plurality of plates can also be arranged, however, preferably only one plate is arranged in the air outlet.

[0019] Alternatively, the movable element can also be an actuating element, such as a sliding grip or an operating wheel. When in the description at certain places the element for guiding and / or restricting an air flow or the plate is mentioned, the teachings described also correspondingly apply to the actuating element.

[0020] For the case where the movement of the movable element is a rotational movement, the main extension direction of the elastic element is at least substantially parallel to the pivot axis of the movable element. When braking the rotational movement of the movable element in a region arranged away from the pivot axis, in the installed state the main extension direction of the elastic element is not particularly concentric with the pivot axis.

[0021] Both solutions according to the invention offer the advantage that the movement force can be adjusted in a defined manner by means of the elastic element.

[0022] Based on a simple construction, it is also possible to simply determine how much frictional force is applied to the entire system by means of the elastic element.

[0023] For the elastic element, spring steel is preferably used, so that no or hardly any relaxation occurs. Thus, a durable product is obtained, wherein the movement force itself can remain constant during continuous actuation.

[0024] Generally, it is possible to minimize the tolerances of individual components and the system tolerances, and this minimization achieves a reduction in the fluctuation of the operating force.

[0025] According to an advantageous improvement of the present invention, the elastic element is arranged in the recess of the movable element.

[0026] This enables an extremely simple (predetermined) positioning of the elastic element relative to the movable element.

[0027] Preferably, the recess is arranged on the end face side of the movable element or the element that guides and / or restricts the air flow. Particularly preferably, a recess is arranged on the end face side respectively, and the elastic element is inserted into the recess. Due to the braking moment generated by symmetry, the plate does not bend. This enables the plate to move smoothly without a sliding blockage effect and at the same time has a smooth operating feel.

[0028] In the described embodiment, the movement between the elastic element and the housing of the air discharge port is braked. Alternatively, it is conceivable that the elastic element is arranged in the housing (such as in a recess), and thus the movement between the movable element and the elastic element is braked.

[0029] According to an advantageous improvement of the present invention, the braking device further has at least one pin, and the pin is arranged on the movable element (such as a plate).

[0030] In this case, on the one hand, the pin can have the function of restricting the movement of the movable element (plate) (end stop) with an associated guiding part (such as a groove). On the other hand, the movement can be transmitted to the plate by means of the pin, so that the pin can be used to adjust the position of the plate.

[0031] In the installed state, the pin preferably extends from the end face of the plate.

[0032] Preferably, two pins are arranged on the plate, so that fixation at both end faces can be achieved.

[0033] In addition, it is conceivable that the pin can also perform other functions. For example, it may be possible to control the drag plates (Schlepplamellen) by means of the pin. Therefore, it may be possible to achieve an additional function of mechanically driving another element (such as another plate by means of a connecting rod).

[0034] According to an advantageous improvement of the present invention, the pin is also arranged in the recess, and in this case, the elastic element is at least partially arranged between the pin and the movable element.

[0035] In other words, first, the elastic element is arranged in the recess, and then the pin is arranged on the elastic element.

[0036] The plate generally has the described pins in any case. Thus, in the described embodiment, it is possible to arrange the elastic element in the plate without providing additional structural space to generate braking of the plate. In addition, in such an embodiment, it is conceivable that the plate can be retrofitted because of the corresponding elastic element.

[0037] Therefore, the pin and the elastic element preferably share a notch. By arranging the elastic element in the same area as the pin, the generation of the force of the moving force is achieved close to the force application point of the actuation.

[0038] According to an advantageous refinement of the invention, the notch, the elastic element and / or the pin have at least one retaining device which is designed to retain the elastic element and / or the pin in the notch.

[0039] In addition, such a retaining device can naturally also be designed to retain the pin on the elastic element or to retain the elastic element on the pin.

[0040] Particularly preferably, at least one (preferably two) retaining device for retaining the elastic element in the notch is arranged, and at least one (preferably two) further retaining device for retaining the pin on the elastic element is arranged. Thus, the elastic element also serves as a connecting element and a closing element between the movable element and the pin.

[0041] In addition, a particularly simple assembly can be achieved by such an embodiment. In particular, during the cost-saving assembly of purely mechanical components, the pin which independently serves as a closing element together with the elastic element also allows more options in terms of the type and sequence of the individual sub-assembly processes.

[0042] Generally speaking, the described retaining device can be manufactured, for example, as a hook element.

[0043] According to an advantageous refinement of the invention, the elastic element is in frictional contact directly or indirectly with a groove and / or a rib as a friction counterpart, such that the movement of the movable element relative to the housing, preferably relative to the housing of the air outlet, is braked.

[0044] By means of the spacing between the elastic element and the groove or the rib, the offset of the elastic element can be adjusted and thus the frictional force (and thus the moving force) can be adjusted. In addition, the moving force can also be adjusted by means of the friction surface between the two friction counterparts.

[0045] By appropriately selecting the material of the friction counterpart, it is possible in this case to achieve hardly any scratching noise or screeching noise and wear.

[0046] "Direct frictional contact" is understood to be such frictional contact in which two elements contact directly (without other elements (such as friction linings) being arranged between them). "Indirect frictional contact" is correspondingly understood to be such frictional contact in which two elements do not contact directly, but there are elements (such as friction linings, sliding coatings) arranged between them.

[0047] According to an advantageous refinement of the invention, the groove or the rib has at least one locking device by means of which the position of the movable element relative to the housing can be fixed.

[0048] By means of such a locking device it is possible to achieve that the movable element (such as a plate) repeatedly moves into or out of a predefined position.

[0049] According to an advantageous refinement, the braking device also has at least one region of the housing (of the air outlet), wherein the region of the housing has the groove or the rib.

[0050] In particular, the groove is curved and is arranged along the movement curve of the movable element. In the case of a pivotable plate, the groove is concentric with the pivot axis of the plate.

[0051] According to an advantageous refinement of the invention, the elastic element extends as at least a single-piece elastic element into the groove and forms a frictional contact with at least one inner side of the groove.

[0052] Thus, the elastic element can move in the groove in a guided manner.

[0053] By means of the above design, the braking device can be easily constructed, wherein the tolerances of the housing length and / or the plate length are no longer so important.

[0054] Preferably, the elastic element has two parts, the outer sides of which form a frictional contact with the inner side of the groove.

[0055] Thus, the width of the groove determines the offset of the elastic part and thus its frictional force relative to the housing. By means of this frictional force, the movement force can subsequently be adjusted. In addition, the force adjustment can of course also be carried out by pre-tensioning the elastic element.

[0056] This embodiment of the elastic element also has the following advantages: The elastic element has two "brakes", which can increase the required frictional torque. Since the two components of the elastic element act on two opposite braking surfaces simultaneously, extremely strong forces are further eliminated, so that no additional force impact is exerted on the surrounding mechanical system. Therefore, it is possible to avoid, to the greatest extent possible, an uncontrolled increase in additional operating forces caused by additional, unplanned, and / or uncontrolled friction counterparts. At the same time, wear caused by the force of the braking spring in the remaining mechanical system at the system outlet can also be avoided by means of this two-component spring.

[0057] Furthermore, in this embodiment, the sum of the frictional forces can be kept approximately constant. For example, if the elastic element is displaced in the direction of one component relative to the center point of the groove, the load on this one component is greater, while the load on the other component decreases. Since the elastic element has a substantially linear characteristic curve, in this case the normal force on one component decreases, and this normal force increases in the same way on the other component, so that the sum of the frictional forces can be kept constant.

[0058] Due to the compensating arrangement of the components, it is even possible to achieve a certain degree of eccentricity between the braking path and the center (pivot axis) of the plate support without changing the braking force.

[0059] According to an advantageous refinement of the invention, the elastic element is at least partially received in a region of the housing and is in frictional contact with at least one frictional surface, in particular with at least one frictional surface of an element that guides and / or restricts the air flow.

[0060] This is the reverse arrangement of the braking device described above, in which the elastic element is no longer arranged in the element that guides and / or restricts the air flow, but in the housing at the outlet. According to the embodiment, the effects described above can also be obtained here.

[0061] According to an advantageous refinement of the invention, a friction element (for example also in the form of a coating of the spring) is arranged between the elastic element and / or the rib, and this friction element acts as a brake lining.

[0062] According to an advantageous refinement of the invention, the elastic element is in direct or indirect frictional contact with at least a substantially roller-shaped friction counterpart, such that the movement of the elastic element relative to the roller-shaped friction counterpart is arrested not only in the radial direction but also in the axial direction, or vice versa.

[0063] Therefore, the braking device is also suitable in principle for braking a translational movement that takes place simultaneously with a rotational movement. In this case, the braking surface or the friction counterpart has, for example, the shape of a roller. In this embodiment, the braking force can thus be adjusted by means of the diameter of the roller. These braking forces can also be varied as a function of the axial extent of the roller, in such a way that the diameter of the roller is changed.

[0064] According to an advantageous refinement of the invention, when the elastic element moves relative to the friction counterpart, it is deflected in different directions due to frictional contact, so that the frictional force between the elastic element and the friction counterpart varies along the movement path.

[0065] In this case, uneven movement forces / operating forces of the mechanical system can be selectively compensated for.

[0066] According to an advantageous refinement of the invention, a plurality, preferably a large number, of elastic elements acting simultaneously are arranged on the movable element.

[0067] Preferably, springs (particularly preferably two springs) are each arranged on the end faces of the movable element or plate.

[0068] By arranging a plurality of elastic elements as brakes, each individual brake only has to be able to generate a desired, smaller frictional torque. Softer springs can thus be used, which in turn is associated with a number of advantages. Softer springs thus avoid excessive wear and / or deformation of the contact surfaces or friction surfaces, and the associated undesired reduction in the braking torque during continuous operation. In addition, a softer spring characteristic curve can be implemented with the aid of softer springs, which results in a direct reduction in the braking torque tolerances associated with the system. In addition, the manufacturing tolerances of the springs can be statistically compensated for by multiple arrangement, and the fluctuations in the operating force are thereby minimized.

[0069] Furthermore, the solution according to the invention consists in providing a device for a vehicle, preferably an air outlet, having: at least one movable element; a housing in which the movable element is movably arranged; and at least one of the above-described braking devices, which is designed to brake the movement of the at least one movable element relative to the housing.

[0070] Since the device or the air outlet has the braking device described, all aspects discussed in connection therewith naturally also apply here.

[0071] Overall, the object set out at the beginning of the article is achieved in a satisfactory manner by means of the braking device described and the air outlet described.

[0072] The present invention will be described in more detail below with reference to the accompanying drawings by way of examples.

[0073] In the drawings:

[0074] Figure 1 Schematic view showing a braking device for braking the movement of at least one movable element (in this case a plate) relative to a housing (in this case an air outlet);

[0075] Figure 2 Shown in enlarged view according to Figure 1 the braking device, in which the housing of the air outlet is not shown;

[0076] Figure 3 Shown according to Figure 1 the braking device, in which the elastic element and the pin of the braking device outside the notch of the element for guiding and / or restricting the air flow are shown; and

[0077] Figure 4 Enlarged view showing the elastic element of the braking device according to the present invention.

[0078] Figure 1 Shown is a braking device 100 for braking the movement of a movable element 1. The movable element 1 is a plate in this case. Therefore, it will also be referred to as plate 1 hereinafter. The plate 1 has a pivot axis A about which the plate 1 can pivot or rotate. At the end face of one end of the plate 1, a support for the plate 1 to be pivotable about the pivot axis A is realized. Preferably, such a pivotable support is realized on the two end faces of the plate 1 at one end (at the front end of the end face in the figure).

[0079] As can be better seen in Figure 2 an elastic element 4 and a pin 3 are also arranged on the end face of the plate 1. In particular, the elastic element 4 and the pin 3 are arranged at the other end of the end face of the plate 1 different from the pivot axis A.

[0080] Therefore, the braking action is not carried out at the support position of the plate 1.

[0081] Although only one end face of the plate 1 can be seen in the figure, the structure of the other end face of the plate 1 is preferably the same as the end face of the plate 1 shown in the figure.

[0082] In the assembled state (as can be seen in Figure 1 ), the pin 3 extends into the groove 5 of the housing 2 of the air outlet.

[0083] The position of the plate 1 (relative to the housing 2 of the air outlet) can be changed, for example, by an operating element (handle / sliding grip) not shown. Thus, for example, it is possible to drive a further (not shown) mechanical element by means of the pin 3.

[0084] Furthermore, by means of the pin 3, the position of the plate 1 (relative to the housing 2 of the air outlet) can be changed.

[0085] As can be seen in Figure 1 the elastic element 4 is tensioned in the groove 5, so that a frictional force is generated between the elastic element 4 and the groove 5.

[0086] In particular, the elastic element 4 has (as can be seen, for example, in Figure 2 two parts 6 and 7, the outer sides or surfaces of which are pressed against the opposite inner surfaces of the groove 5 in certain regions.

[0087] The width of the groove 5 in the housing 2 of the air outlet determines the possible displacement of the parts 6 and 7, so that the frictional force of the parts 6 and 7 relative to the groove 5 can also be adjusted by the width of the groove. In addition, the frictional force can also be changed by changing the pre-tension of the elastic element 4.

[0088] If the plate 1 does not move, a normal force is exerted on the inner side of the groove 5 by the parts 6 and 7. If the plate 1 rotates about its pivot axis A, frictional forces are caused by these normal forces, and these frictional forces determine the movement force of the plate 1. In other words, the elastic element 4 rubs with its parts 6, 7 against the inner surface or the inner side of the groove 5 and thereby generates a frictional force.

[0089] Since this is a particularly simple arrangement, it is possible to predict the movement forces in the system and to calculate these movement forces by means of the spring characteristics and the coefficient of friction. Thus, even before the start of development, it is possible to come very close to the characteristics required in mass production.

[0090] As can be seen in Figure 1 by means of the braking device 100 according to the invention, it is also possible to compensate for tolerances in production. For example, if the pivot axis A is displaced relative to the center point of the groove 5, one of the two parts (for example part 6) is less loaded, while the other part (for example part 7) is more heavily loaded. Since the spring has a substantially linear characteristic curve, the normal force decreases on one part 6 and increases in the same way on the other part 7. Thus, the frictional force remains almost constant in total.

[0091] Manufacturing-related fluctuations in the width of the groove 5 are further compensated by as soft a spring characteristic curve as possible, so that fluctuations in the movement force remain within the tolerances.

[0092] Furthermore, the spring force can be controlled by means of the groove width on the groove path and can thus compensate, for example, for tolerances related to the final position of the entire mechanical system.

[0093] As can be seen in Figure 2 the elastic element 4 is arranged together with the pin 3 in the same recess 12 of the plate 1. In the installed state, only the distal end of the pin 3 protruding from the recess 12 can be seen. Similarly, only the distal ends of the parts 6 and 7 of the elastic element 4 protruding from the plate 1 or the recess 12 can be seen.

[0094] As can also be seen in Figure 2 in the installed state, the main extension direction of the elastic element 4 and, independently thereof, also the main extension direction of the pin 3 are at least substantially perpendicular to the movement path or movement direction of the plate 1. That is, the pin 3 and, independently thereof, the elastic element 4 are arranged in the installed state such that their main extension direction (i.e., the direction in which the main extension part (the longest extension part) lies; (also the axis of symmetry in the pin)) is arranged or oriented perpendicular to the movement path.

[0095] In the case shown in the figure, in which the movement is a rotational movement about the pivot axis A, it also applies that: the pin 3 and, independently thereof, the elastic element 4 are arranged in the installed state such that their main extension direction (i.e., the direction in which the main extension part (the longest extension part) lies; (also the axis of symmetry in the pin)) is arranged or oriented parallel to the pivot axis A.

[0096] By arranging the pin 3 and the elastic element 4 in the same recess 12, the following advantage is furthermore obtained: the generation of the force of the movement force can be achieved close to the force application position of the actuation.

[0097] From Figure 3 and Figure 4 it can be seen that the pin 3 and the elastic element 4 can be firmly clamped in the plate 1 in a non-forced locking and forced locking manner by means of a suitable geometry (such as the retaining devices 8, 9, 10, and 11). Thus, the elastic element 4 is held in the recess 12 of the plate 1 by means of the hook elements 10 and 11 formed on the elastic element 4. The pin 3 is in turn held in the elastic element 4 by means of additional hook elements 8 and 9.

[0098] Here, the pin 3 supports and locks simultaneously to fix the elastic element 4 in the plate 1 by correspondingly tensioning all the hook elements 8, 9, 10, and 11 at the same time. Thus, it is ensured that the elastic element 4 and the pin 3 are held in the recess 12 in a loss-proof manner.

[0099] Naturally, it may also be conceivable in this regard that one or more hook elements acting simultaneously, similar to 8, 9, 10, and 11, can be used. It may also be conceivable to have a solution with only one elastic member or a solution with multiple elastic members or elastic arms extending in the same direction.

[0100] It may also be conceivable to use it in a linear or curvilinear guided motion. Instead of the slot 5, it may also be conceivable to have parallel ribs that, for example, guide the pin 3 and / or are actively connected to the elastic element 4. In such ribs, an embodiment may also be conceivable in which the normal force acts not from the inside but from the outside on a single rib. It may also be conceivable that the two parts of the elastic element 4 act in opposite directions.
