Description

Technical Field

[0001] This invention relates to an air vent for a motor vehicle, comprising a housing having an air passage having an inlet opening and an outlet opening at an end of an end section opposite to the inlet opening, wherein the cross-section of the air passage gradually tapers toward the outlet opening in the end section, wherein the air passage has a passage wall dividing the air passage into first and second sub-channels in its longitudinal extension from the inlet opening to the outlet opening, wherein first and second air guiding elements are arranged in the air passage between the inlet opening and the sub-channels, wherein the first air guiding element is pivotable about a first pivot axis and associated with the first sub-channel, wherein the second air guiding element is pivotable about a second pivot axis and associated with the second sub-channel, and wherein the passage wall terminates in a region of the end section, thereby allowing adjustment of the outflow direction from the outlet opening according to the pivot position of the air guiding element.

[0002] Furthermore, the present invention relates to a motor vehicle having such an air vent. Background Technology

[0003] The type of air outlet mentioned at the beginning is known from the prior art. For example, documents DE 10 2017011 180 A1, DE 10 2018 105 747 A1, DE 10 2019 130 062 A1, DE 20 2019 005119 U1 and CN 110 978 961 A respectively disclose this type of air outlet. Summary of the Invention

[0004] The purpose of this invention is to provide an improved air outlet that ensures increased flexibility when closing air passages.

[0005] The object of the invention is achieved by an air outlet having the features of claim 1. According to the invention, the pivot axis is arranged accordingly in the longitudinal extension of the respective air guide element, at the respective air guide element, and in the air passage, such that the air guide elements, respectively, at least substantially close the air passage and partially overlap each other in the first and second final pivot positions. The air outlet according to the invention provides a particularly advantageous and flexible possibility for closing the air passage, unlike the known solutions mentioned at the beginning, which ensures closure in both final pivot positions of the air guide element. Thus, the air passage can be quickly closed by corresponding selection of the pivot direction of the air guide element, independent of the actual pivot position, because at least one of the two final pivot positions can always be quickly reached with a limited pivot angle. The air guide element completely closes the air passage, particularly in the respective final pivot positions, i.e., causing complete locking. The air outlet is here constructed as a so-called flow vector outlet. The outflow direction and air deflection of an air passage with two sub-channels (i.e., a flow vector outlet) are controlled by the pivoting position of the air guiding element. For example, the sub-channels merge with each other in the end section, thereby achieving opposite outflow directions. The exhaust opening, as an outlet, can be associated with or related to the interior space of a motor vehicle.

[0006] According to a preferred embodiment of the invention, the pivot axes are arranged parallel to each other and transverse to the longitudinal extension orientation of the air passage. This arrangement and orientation provides the advantage that the air guiding elements can pivot with particular flexibility.

[0007] Particularly preferably, the pivot axis is arranged such that the parallel and opposite edges of the corresponding air guide elements are at the same distance. This advantageously maximizes the possible pivot angle of the corresponding air guide elements, as the air guide elements can thus pivot as far as possible in both pivot directions without impacting the housing.

[0008] According to a preferred improvement of the invention, the air passage leading to its outlet opening is configured such that at least one of the two sub-passages has at least one bend. This bend provides an advantageous possibility for determining the outflow direction of airflow from the respective sub-passage. The air passage has bends, particularly in both sub-passages, wherein the bends preferably open to each other, thereby achieving opposite outflow directions.

[0009] Particularly preferably, the two sub-channels are arranged such that they extend at least partially parallel to each other or at a predetermined angle. This advantageously ensures that the channel walls separating the two sub-channels are constructed with particular geometric simplicity. For example, the sub-channels extend accordingly in an arc shape. Viewed in longitudinal section of the sub-channels, the channel walls are constructed, for example, in a teardrop, oval, or elliptical shape. Preferably, the flow paths through the two sub-channels are at least approximately equal in length.

[0010] According to a preferred improvement of the invention, the air guiding element is pivoted at least 150°, preferably 180°, relative to the first final pivot position in the second final pivot position. This provides the advantage that the two final pivot positions are as far apart as possible with respect to their relative pivot angles, thereby advantageously further improving overall flexibility.

[0011] Particularly preferably, in the first final pivot position, the first air guide element is positioned such that its side facing away from the inlet opening rests against the side of the second air guide element facing the inlet opening, and in the second final pivot position, the first air guide element is positioned such that its side facing the inlet opening rests against the side of the second air guide element facing away from the inlet opening. This provides a geometrically simple solution for achieving the respective final pivot positions and closing the air passage.

[0012] According to a preferred improvement of the invention, the air guiding element is arranged such that, in the first and second final pivot positions, it abuts against the housing at its end opposite to the corresponding other air guiding element. This provides a particularly advantageous and simple geometric definition of the final pivot position. In this respect, the housing forms a stop for reaching the respective final pivot position.

[0013] Particularly preferably, at least one additional exhaust opening is arranged in the air passage between the inlet opening and the air guiding element. This additional exhaust opening advantageously ensures that the airflow can be flexibly distributed, especially in the corresponding final pivot position of the air guiding element, where only the airflow is guided through this exhaust opening.

[0014] According to a preferred embodiment of the invention, the air guiding elements can be constructed to pivot independently of each other. This further improves the flexibility in distributing airflow.

[0015] Particularly preferably, the air guiding elements are configured to be pivotally coupled to each other. This provides a particularly advantageous possibility that they can reach their respective final pivot positions simultaneously.

[0016] According to a preferred embodiment of the invention, the air guide element is associated with one or more manually operable operating elements, particularly rotary elements or operating levers, for pivoting the air guide element. This provides a particularly advantageous and simple possibility for adjusting the corresponding pivot angle of the air guide element. The operating element is particularly constructed as a mechanical (especially rotatable) operating part, such as a knob, operating wheel, operating roller, or sliding element.

[0017] Particularly preferably, the air guide element is associated with one or more operable, particularly electric, actuators for pivoting the air guide element. This provides a particularly advantageous and simple possibility for adjusting the corresponding pivot angle of the air guide element. The actuator is particularly constructed as an electric servo motor. The actuator is particularly attached to a manually operable operating element, as described above.

[0018] The motor vehicle with the features of claim 14 is characterized by the air outlet according to the invention. This results in the advantages already mentioned. Attached Figure Description

[0019] Further advantages, preferred features, and combinations thereof will be apparent, particularly from the foregoing description and from the claims. The invention will now be described in more detail with reference to the accompanying drawings. Figures 1 to 4 The advantageous air outlet is shown in different operating conditions. Detailed Implementation

[0020] Figures 1 to 4 The advantageous air outlet 1 is shown in longitudinal section. The air outlet 1 is constructed as a so-called flow vector outlet. Here, the air outlet 1 has a housing 2. The housing 2 has an air passage 3. The air passage 3 has an inlet opening 4 and an outlet opening 5.

[0021] Here, the discharge opening 5 is located at the end of the end section 6 of the air passage 3, opposite to the inlet opening 4. The cross-section of the air passage 3 gradually tapers towards the discharge opening 5 in the end section 6. Therefore, overall, the cross-section of the inlet opening 4 is larger than the cross-section of the discharge opening 5.

[0022] The air passage 3 has a passage wall 7. The passage wall 7 currently has a three-dimensional profile in the longitudinal section, at least approximately in the shape of a pointed ellipse. It is constructed in a particularly flow-advantageous manner. The passage wall 7 divides the air passage 3 into a first sub-passage 8 and a second sub-passage 9 in its longitudinal extension from the inlet opening 4 to the outlet opening 5.

[0023] Sub-channels 8 and 9 have at least segmentally identical constant cross-sections. These two sub-channels 8 and 9 extend at least locally parallel to each other and at predetermined angles to each other, thus generally creating an arc shape. Sub-channels 8 and 9 are arranged and constructed in particular with mirror symmetry, wherein the axis of symmetry extends through the channel wall 7 or in the longitudinal extension of the channel wall 7.

[0024] In air passage 3, a first air guiding element 10 and a second air guiding element 11 are arranged between the inlet opening 4 and sub-passages 8 and 9. The first air guiding element 10 is pivotable about a first pivot axis 12 and associated with the first sub-passage 8. The second air guiding element 11 is pivotable about a second pivot axis 13 and associated with the second sub-passage 9.

[0025] The air guide elements 10 and 11 are configured to pivot independently of each other or coupled to each other. For example, each air guide element 10 and 11 is associated with one or more manually operable operating elements (not shown), in particular a rotary element or operating lever, for pivoting the air guide elements 10 and 11. Alternatively or additionally, each air guide element 10 and 11 is associated with one or more equally operable, in particular electric actuators (not shown) for pivoting the air guide elements 10 and 11.

[0026] Here, the channel wall 7 terminates in the region of the end section 6, thereby adjusting the outflow direction from the discharge opening 5 according to the pivot position of the air guiding elements 10, 11. Figures 1 to 4 That's the difference.

[0027] Thus in Figure 1 As shown, the air guiding elements 10, 11 are respectively parallel to each other and parallel to the longitudinal extension orientation of the air passage 3, thereby uniformly distributing the airflow 14 (shown in dashed lines) onto the two sub-passages 8, 9 and following their curved direction until the resulting partial airflow meets again in the region of the end section 6 and leaves the exhaust opening 5 at least largely without deflection, i.e. in a straight line or in the same flow direction as it entered the inlet opening 4.

[0028] exist Figure 2 As shown, the air guiding elements 10, 11 are pivoted in a first pivot direction (clockwise with respect to the shown observation direction) such that the second sub-channel 9 is at least partially covered by the second air guiding element 11. This enhances the guidance of airflow 14 through the first sub-channel 8, wherein when the resulting partial airflow re-encounters in the region of the end section 6, it deflects downwards away from the exhaust opening 5 with respect to the shown observation direction.

[0029] This deflection is achieved by the air passage 3 leading to its exhaust opening 5 having a corresponding bend in each of the two sub-passages 8, 9, wherein the sub-passages 8, 9 bend in opposite directions. The airflow then flows, for example, along the upper and lower decorative covers 15, 16 arranged at the housing 2 into the interior space of the vehicle.

[0030] The air outlet 1 is now characterized in that it allows the air guiding elements 10, 11 to pivot to the first and second final pivot positions respectively. This is achieved by the pivot axes 12, 13 being arranged, respectively, at the corresponding air guiding elements 10, 11 in the longitudinal extension of the respective air guiding elements 10, 11.

[0031] The pivot axes 12 and 13 are arranged parallel to each other and transverse to the longitudinal extension orientation of the air passage 3. The pivot axes 12 and 13 respectively have the same distance between the first edge 20 and the second edge 21 of the corresponding air guiding elements 10 and 11. The second edge 21 is parallel to the first edge 20 and faces away from the first edge 20.

[0032] Pivoting axes 12, 13 are arranged in the air passage 3 such that the air guiding elements 10, 11, respectively, in the first and second final pivot positions, at least substantially close the air passage 3 or sub-passages 8, 9, and are partially overlapping each other. The air guiding elements 10, 11 here respectively have a first side 17 and a second side 18 facing away from each other.

[0033] Depending on the pivot position, one of the sides 17, 18 may face or be directed toward the entry opening 4 or the airflow 14. Thus, in the first final pivot position, the first side 17 of the corresponding air guide element 10, 11 faces the entry opening 4, while in the second final pivot position, its second side 18 faces the entry opening 4.

[0034] exist Figure 3 The image shows the air guide elements 10, 11 corresponding to the first final pivot position. If the air guide elements 10, 11 are moved from their respective positions... Figure 2 Starting from the pivot position shown, the elements pivot further in the same pivot direction until they are just abutting each other, reaching that position. In the first final pivot position, the first air guide element 10 is correspondingly abutted against the first side 17 of the second air guide element 11 facing the entry opening 4 with its second side 18 facing away from the entry opening 4.

[0035] exist Figure 4 The image shows the air guide elements 10, 11 in the second final pivot position. If the air guide elements 10, 11 are moved from... Figure 1 Depart along the second pivot direction or synonymously from in Figure 2Starting from the pivot position shown, pivot in the opposite pivot direction until they come into contact with each other again, reaching that position.

[0036] In this second final pivot position, the air guiding elements 10, 11 are pivoted at least 150° relative to the first final pivot position. In the second final pivot position, the first air guiding element 10 is correspondingly abutted against the first side 17 of the second air guiding element 11 opposite to the entry opening 4 with its second side 18 facing the entry opening 4.

[0037] In other words, the air guiding elements 10 and 11 abut against each other with the same sides 17 and 18 in both final pivot positions. In the first final pivot position, the first air guiding element 10 abuts against the second air guiding element 11 in the region of its first edge 20 and the region of the second edge 21 of the second air guiding element. In the second final pivot position, the first air guiding element 10 abuts against the second air guiding element 11 in the region of its second edge 21 and the region of the first edge 20 of the second air guiding element.

[0038] In the first and second final pivot positions, the air guide elements 10, 11 are respectively abutted against the housing 2 at their ends opposite to the corresponding other air guide element 10, 11, such that the air passage 3 is completely closed in the direction of at least the two sub-passages 8, 9. In other words, the air guide elements 10, 11 are respectively abutted against the housing 2 with the first or second edge 20, 21.

[0039] The first air guiding element 10 is positioned with its second edge 21 in the first final pivot position and with its first edge 20 in the second final pivot position, and the second air guiding element 11 is positioned with its first edge 20 in the first final pivot position and with its second edge 21 in the second final pivot position.

[0040] The air passage 3 currently has two additional, particularly closable, discharge openings 19 perpendicular to the inlet opening 4 and the outlet opening 5 between the inlet opening 4 and the air guide elements 10, 11. If the air guide elements 10, 11 are in one of their final pivot positions, the airflow 14 will flow through the discharge opening 19 as long as it is open.
