Technical Field

The present invention relates to a vent hole, with which, in particular, the air outflow direction can be adjusted in the vertical direction and the lateral direction.

Background

Disclosure of Invention

In contrast, it is an object of the present invention to create an alternative to known ventilation holes.

The problem addressed by the present invention is solved by a vent having the features of the independent claims. Further developments and preferred embodiments of the invention will be described in the following description and the dependent claims.

It is presented a vent comprising:

a first air passage is formed in the first air passage,

a second air passage, and

an air conditioning flap pivotable about a flap axis for setting a ratio between a first air flow through the first air passage and a second air flow through the second air passage, wherein the air conditioning flap closes the first air passage in a first position and the air conditioning flap closes the second air passage in a second position.

The vent hole further includes:

a plurality of first vanes disposed at least partially in the first air passage, wherein each first vane is pivotable about a first vane axis,

a plurality of second vanes at least partially disposed in the second air passage, wherein each second vane is pivotable about a second vane axis, an

A manipulator coupled to the first blade, the second blade, and the air conditioning flap for adjusting the first blade, the second blade, and the air conditioning flap.

The ventilation aperture is characterized by its simple design. The air conditioning flap is generally movable between a first position in which the first air passage is fully closed by the air conditioning flap and a second position in which the second air passage is fully closed by the air conditioning flap. In an intermediate position between the first position and the second position, the air flow entering the vent is divided by the air conditioning flap into two air flows, a first air flow and a second air flow. At a particular intermediate position, a ratio may be selected such that a first air flow through the first air passage and a second air flow through the second air passage are of the same magnitude. The first air passage is disposed generally vertically above the second air passage. Therefore, by pivoting the air-conditioning flap, the distribution of air flowing out of the ventilation hole in the vertical direction can be influenced. Usually, only a single air-conditioning flap is provided, whereby the ventilation aperture can have a particularly simple design.

By means of the first and second blades, the lateral direction of the air flowing out of the ventilation hole can be changed according to the direction of the first and second blades. The lateral air outflow direction can be influenced, for example, in a horizontal plane perpendicular to the vertical outflow direction by adjusting the blades.

Since the manipulator is coupled to the first blade, the second blade, and the air-conditioning flap, and is designed to adjust it, the directional characteristic of the discharged air flow in the vertical direction and the lateral direction can be changed by a single manipulator.

In one embodiment, the manipulator is displaceable in a direction parallel to the lamella axis. Displacement of the manipulator may cause pivotal movement of the first and second blades, thereby changing the lateral air outflow direction. Here, a displacement is a movement that translates laterally (e.g., to the left or right), for example.

The vent may have a coupling member connecting the first and second blades to the manipulator. The coupling member may have a first end, a second end, and an intermediate piece disposed between the first and second ends. In one embodiment, a first end of the coupling member is connected to the first blade, an intermediate piece of the coupling member is connected to the second blade, and a second end of the coupling member opposite the first end is connected to the manipulator. It may be provided that the coupling member is connected to only one of the plurality of first blades and/or one of the plurality of second blades. In this case, the plurality of first blades may be connected to each other by the first engaging coupling element so that the plurality of first blades can move in synchronization with one first blade coupled to the coupling member. It can also be provided that a plurality of second blades are connected to one another by second joint coupling elements, so that all second blades can be rotated simultaneously.

The coupling member may be connected to the first blade or the first plurality of blades in different ways. For example, the first end of the coupling member includes a first guide slot in which the first pin is engaged. The first pin is rigidly connected to the first vane or vanes, for example by a lever arm. In this way, a translational displacement of the manipulator in the transverse direction may be converted into a rotational or pivotal movement of the first blade by the coupling member. Similarly, the intermediate piece of the coupling member may have a second guide groove in which the second pin is engaged. The second pin is rigidly connected to one or more of the second plurality of vanes by a lever arm.

In one embodiment, the manipulator is rotatable about a manipulator axis. Rotation of the operator about the operator axis may cause pivotal movement of the air conditioning flap about the flap axis. In one variation, a downward or upward rotational movement of the manipulator causes a downward or upward pivotal movement of the air conditioning flap. In one embodiment, the manipulator axis and the flap axis are oriented parallel to each other.

The air vent may have a coupling rod disposed between and connected with the manipulator and the air-conditioning flap. For example, a first lever arm and a second lever arm are provided, wherein the first lever arm is rigidly connected to the air flap and is hingedly coupled to the coupling rod, wherein the second lever arm is rigidly connected to the manipulator and is hingedly coupled to the coupling rod.

The first and second blades are, for example, rotatably mounted on a first blade shaft and a second blade shaft, respectively. The vane shaft and the second vane shaft may be connected to the coupling member described above. The first vane axis generally passes through the first vane shaft from the center and the second vane axis generally passes through the second vane shaft from the center. The first vane shafts or the first vane axes are preferably parallel to one another. And the second blade axes or the second blade axes may be oriented parallel to each other. Furthermore, the first blade shaft or axis and the second blade shaft or axis may be oriented parallel to each other. The first blade axis and/or the second blade axis may be oriented perpendicular to the door blade axis and/or perpendicular to the manipulator axis. In one embodiment of the ventilation hole, the first blade is disposed above the air conditioning flap and the second blade in the vertical direction.

In another variant, the first air channel and the second air channel are separated from each other by a separating element. The separating element is preferably rigidly connected to the housing of the vent. Typically, the first air passage and the second air passage meet each other upstream of the separation element. This region before upstream (that is, before the air stream is divided into the first air stream and the second air stream) may be referred to as an air inlet. The air-conditioning flap may be provided at an end of the separating element facing the air inlet. The separating element typically forms an upper boundary of the second air channel and a lower boundary of the first air channel. Optionally, the shape of the separating element is conical in the direction of the air inlet. Furthermore, the separating element may have a cavity. In one embodiment, the manipulator, the coupling member and/or the coupling rod are arranged in the cavity of the separating element at least in some areas. The separating element can thus not only form a guide for the gas flow and separate it in two channels, but also form a housing for the coupling member and the manipulator of the coupling rod.

In one embodiment, the first blade axis lies in a first plane. The second blade axis may lie in a second plane, wherein the first plane and the second plane are different from each other. The first and second planes are preferably parallel to each other. The first and second planes may also be parallel to the lamella axis. Furthermore, the first vane may be arranged between the air-conditioning flap and the second vane in the flow direction.

In one embodiment, the first air channel and the second air channel have different lengths. In particular, they may have different lengths in the flow direction. Further, the first vane may be closer to the air inlet than the second vane.

All or a single one or several of the above-mentioned components may be produced by an injection moulding process. For example, the air-conditioning flap, the first blade, the second blade, the manipulator, the coupling member, the coupling rod, the lever arm described above, the first blade shaft, the second blade shaft, the coupling element described above, the guide groove, the pin and the separating element are injection-molded components, for example made of a thermoplastic or thermosetting material.

Furthermore, a vehicle interior trim component is proposed, which comprises a vent hole according to any of the preceding embodiments. The vent is therefore particularly suitable for mounting in a vehicle interior. Here, the vent may be fluidly connected to a fan, heater or air conditioning unit, and may be disposed behind (downstream of) one of these elements.

Of course, the above-described embodiments may be combined with each other in any manner as long as the combinations are not mutually exclusive.

Detailed Description

Hereinafter, the same elements will be denoted by the same reference numerals.

Hereinafter, fig. 1 to 4 are first referred to.

Fig. 1 to 4 show different views of the ventilation opening 1. The vent hole 1 is a part of a vehicle interior trim component, and the vent hole 1 includes a housing 33 and a separate element 30 that is rigidly arranged with respect to the housing 33. The first air passage 2 and the second air passage 3 are formed between the housing 33 and the separating member 30. Furthermore, the vent 1 has an air inlet 29, which air inlet 29 may be fluidly connected to a fan (not shown) or an air conditioning unit (not shown) or a heater. The airflow through the air inlet 29 is directed through the first air passage 2 and/or the second air passage 3 and then into the vehicle interior (not shown). The air-conditioning flap 4 is fixed to the end of the separating element 30 facing the air inlet 29 and is pivotable about the flap axis 5. If the air-conditioning flap 4 is completely pivoted downward, the second air passage 3 is closed, whereby the entire air flow flows through the first air passage 2. In contrast, if the air-conditioning flap 4 abuts fully upward against the housing 33, the first air passage 2 is closed, whereby the entire air flow is guided through the second air passage 3. Therefore, the ratio between the first air flow passing through the first air passage 2 and the second air flow passing through the second air passage 3 can be adjusted by the air-conditioning flap 4. By not pivoting the air adjustment flap fully upward or fully downward, the ratio between the first air flow and the second air flow can be set arbitrarily.

A plurality of first vanes 6 are arranged in the first air passage 2. Further, a plurality of second vanes 8 are arranged in the second air passage 3. Each first blade 6 is pivotably mounted about a first blade axis 7 and each second blade 8 is pivotably arranged about a second blade axis 9. The first blade 6 and the second blade 8 are arranged on a first blade shaft 18 and a second blade shaft 19. When the vane shaft 18 and the vane shaft 19 rotate, the first vane 6 and the second vane 8 rotate about their vane axes 7 and 9 in the air passage 2 and the air passage 3, respectively. Thus, the direction of movement of the first air flow through the first air passage 2 and the direction of movement of the second air flow through the second air passage 3 can be influenced in the lateral direction.

In order to pivot air-conditioning door leaf 4, first leaf 6 and second leaf 8 about their respective axes 5, 7 and 9, a manipulator 10 is provided which is coupled to first leaf 6, second leaf 8 and air-conditioning door leaf 4, and by means of manipulator 10, first leaf 6, second leaf 8 and air-conditioning door leaf 4 can be adjusted.

The adjustment of the first blade 6 and the second blade 8 will first be discussed below.

The manipulator 10 is displaceable in a direction 34 parallel to the lamella axis 5, wherein a displacement of the manipulator 10 causes a pivoting movement of the first blade 6 and the second blade 8. The displacement is typically performed in the transverse direction 34. The manipulator 10 is rigidly connected to the coupling member 11 in a transverse (horizontal) direction 34. The coupling member 11 connects the first blade 6 and the second blade 8 to the manipulator 10. Here, a first end 12 of the coupling member is connected to the first blade 6, an intermediate piece 13 of the coupling member 11 is connected to the blade 8, and a second end 14 of the coupling member 11 is connected to the manipulator 10. The first end 12 of the coupling member 11 comprises (see fig. 5 and 6) a guide slot 22, in which guide slot 22 a pin 23 is engaged, wherein the pin 23 is rigidly connected to the blade 31 of the first blade 6 by a lever arm 24. Since the plurality of first blades 6 are connected to each other by the first coupling elements 20, the plurality of first blades 6 can be pivoted at the same angle at the same time. The intermediate piece 13 of the coupling member 11 comprises a second guide slot 25, in which second guide slot 25 a second pin 26 engages. The second pin 26 is rigidly connected to a blade 32 from the second set of blades 8 by another lever arm 27. The second plurality of blades 8 are also connected to each other by the second engaging coupling member 21 so that the second plurality of blades 8 are rotated synchronously at the same angle. Thus, if one of the blades 6 or one of the blades 8 of the plurality of blades moves, the other blades 6 or the other blades 8 also move. By means of the coupling member 11, a translational movement of the manipulator 10 in the transverse direction 34 can be converted into a pivotal movement of the blades 6 and 8 (see fig. 10 and 11). In case of a displacement of the manipulator, the first blade 6 and the second blade 8 are thus pivoted simultaneously and synchronously in the same direction. If the manipulator 10 is moved to the left or right, the blade 6 and the end of the blade 8 disposed downstream are also moved to the left or right.

The pivotal movement of the air-conditioning flap 4 by the manipulator 10 will be described below. For this reason, fig. 7 to 11 are additionally referred to. The fundamental difference with the vent 1 of fig. 1 to 6 is that the vent 1 of fig. 7 to 11 shows the coupling of the manipulator 10 with the air conditioning flap 4 in more detail.

The manipulator 10 is rotatable about a manipulator axis 28, wherein a rotation of the manipulator 10 about the manipulator axis 28 causes a pivoting movement of the air-conditioning flap 4 about the flap axis 5. In one embodiment, the manipulator axis 28 is parallel to the lamella axis 5. A downward or upward rotational movement of the manipulator 10 may cause a downward or upward pivotal movement of the air conditioning flap 4 about the flap axis 5, respectively.

In one embodiment, the coupling rod 15 is disposed between the manipulator 10 and the air-conditioning flap 4 and connected with the manipulator 10 and the air-conditioning flap 4. The coupling rod 15 is hingedly connected to a first lever arm 16 and a second lever arm 17. Here, the first lever arm 16 is rigidly connected to the air flap 4 and the second lever arm 17 is rigidly connected to the manipulator 10. While one end of the second lever arm 17 is rigidly connected to the manipulator 10 and the second end of the second lever arm 17 is hingedly connected to the coupling rod 15 and is movable parallel to the axis of rotation. This is evident in particular from the detailed description of the coupling of the manipulator 10 with the coupling rod 15 of fig. 7 to 11. The coupling rod 15 may, for example, have a cylindrical recess 36 at one end, which passes through a rod 37 connected to the lever arm 17 via the coupling rod 15. The rod 37 is free to slide back and forth in the recess 36 in the transverse direction. By means of the described transmission of forces, a pivoting of the manipulator 10 about the manipulator axis 28 can be converted into a pivoting movement of the air-conditioning flap 4 about the flap axis 5 in the same direction. At the same time, the translational movement of the manipulator 10 is prevented from pushing the coupling rod 15 sideways in the transverse direction 34. A transverse fixing 35 is arranged in the cavity of the separating element 30 and is rigidly connected to the separating element 30, which transverse fixing 35 can contribute to transversely fixing the coupling rod 15.

As can also be seen clearly in fig. 1 to 11, the first blade 6 is rotatable about a first blade axis 7 and the second blade 8 is rotatable about a second blade axis 9. The first vane axis passes through the first vane shaft 18 from the center, and the second vane axis 9 passes through the second vane shaft 19 from the center. The first plurality of vane axes 7 are parallel to each other. Furthermore, the plurality of second blade axes 9 are parallel to each other. Furthermore, the first and second blade axes 7, 7 are oriented parallel to one another. The first blade axis 7 lies in a first plane and the second blade axis 9 lies in a second plane. In this embodiment, the first and second planes are parallel to each other and to the lamella axis 5. As can also be clearly seen from fig. 1 to 11, the first plane and the second plane are different from each other. Furthermore, the first vane 6 is arranged between the air-conditioning door leaf 4 and the second vane 8 in the flow direction. In other embodiments, it can also be provided that a second blade is arranged in the flow direction between the air-conditioning flap 4 and the first blade.

In the exemplary embodiment shown, the first air channel 2 and the second air channel 3 have different lengths. In particular, the first air channel is shorter in the flow direction than the second air channel 3. In other exemplary embodiments, the second air channel 3 may also be shorter than the first air channel 2. The first and second planes are also oriented parallel to each other.

As can also be seen from fig. 1 to 11, the first vane 6 is arranged vertically above the air-conditioning flap 4 and the vane 8. The first blade shaft 18 is rotatably mounted on the separating element 30, wherein the second blade shaft 19 is likewise rotatably mounted on the separating element 30. In another embodiment, first blade 6 and/or second blade 8 are rotatably mounted on housing 33. The separating element 30 comprises a cavity in which the vanes 6 and 8 and the different elements of the adjustment device of the air-conditioning flap 4 are arranged. Thus, the components of the manipulator 10, the coupling member 11 and the coupling rod 15 are arranged in separate elements.

The movable parts of the ventilation opening 1, i.e. in particular the air-conditioning flap 4, the first blade 6, the second blade 8, the manipulator 10, the coupling member 11, the coupling rod 15, the lever arm 16, the lever arm 17, the blade shaft 18, the blade shaft 19, the coupling element 20, the coupling element 21, the lever arm 24, the lever arm 27 and the pins 23, 26, may be injection-molded parts made of thermoplastic material.

With the above-described adjustment devices of the air-conditioning flap 4, the first blade 6, and the second blade 8, the directional characteristic of the discharged air flow in the vertical and horizontal directions can be changed by the separate manipulator 10.

As described above, the vent hole 1 can be used particularly for the vehicle interior. The invention therefore also proposes a vehicle interior trim part comprising a vent hole 1 as described above.
