Description

Technical Field

[0001] This invention relates to an air guiding device. Background Technology

[0002] This type of air intake device is typically used to regulate the air intake at the front of a vehicle. Here, air intake is regulated by means of flap-like enclosed elements. In most cases, these air intake flaps can be adjusted by an electrically driven mechanism.

[0003] FR3051735A1, DE102014106605A1, DE10306158A1 and EP0500430A1 describe air guiding devices.

[0004] Both the drive unit and the air conditioning blades must be supported accordingly within the air guiding device. Existing technology provides a dedicated support frame, which must be positioned between the air inlet component and the air guiding channel through which air enters the air guiding device from the outside. Typically, a corresponding seal must also be introduced between the support frame and the air guiding channel or air inlet component in a sandwich structure configuration. The support frame houses both a rotating support for the air conditioning blades and a mounting mechanism for the drive unit.

[0005] Based on this sandwich structure, a series of components must be installed before the air guiding device can be put into use. Naturally, the more components used, the higher the associated costs of manufacturing them. Summary of the Invention

[0006] The objective of this invention is to further improve the type of air guiding device mentioned at the beginning, so as to reduce the installation cost compared with conventional solutions.

[0007] This task is solved by an air guiding device having features according to the invention.

[0008] An air guide device, particularly suitable for regulating air intake in the front of a vehicle according to the invention, has an air intake component through which air can enter the air guide device. Furthermore, the air guide device also has an air guide channel disposed downstream of and connected to the air intake component. This air guide channel guides the air entering via the air intake component. Here, the air guide device has at least one air conditioning flap pivotally supported on a pivot support device. The at least one air conditioning flap is arranged and configured such that it can influence the airflow entering via the air intake component by changing its pivoting position. According to the invention, the pivot support device for the at least one air conditioning flap is formed by a first support section and a second support section, the first support section being part of the air intake component and the second support section being part of the air guide channel. Therefore, the pivot support device is only generated when the components of the air guide device, namely the air intake component, the air guide channel, and the air conditioning flap, are assembled. In this way, the otherwise common support frame can be eliminated without substitution. Therefore, the solution according to the invention reduces the number of required components and thus lowers the cost. In addition, structural space can certainly be saved because a component is eliminated without any alternative.

[0009] According to a preferred embodiment of the invention, a fixing element, particularly a fixing flange, is provided in the region of the end face of the air inlet component facing the air guide channel, particularly on the end face of the air inlet component facing the air guide channel, and / or in the region of the end face of the air guide channel facing the air inlet component, particularly on the end face of the air guide channel facing the air inlet component. This fixing element can, for example, be used to secure two components (one being the air guide channel and the other being the air inlet component) together. In corresponding designs with a clip function, this can also be achieved without tools. This further simplifies installation, as no additional fixing element is required. In preferred designs of components made of plastic or similar materials, this fixing element, particularly the fixing flange, can be molded onto the corresponding component.

[0010] A similar situation applies to sealing elements used to form a connection between the air inlet component and the air guide channel as airtight as possible, so that no air can escape at the connection. Therefore, according to a preferred embodiment of the invention, a sealing element, particularly a surrounding element, may be provided in the region of the end face of the air inlet component facing the air guide channel, especially on the end face of the air inlet component facing the air guide channel, and / or in the region of the end face of the air guide channel facing the air inlet component, especially on the end face of the air guide channel facing the air inlet component.

[0011] Ideally, as few components as possible should be used to maintain the lowest possible installation cost. For this purpose, for example, it can be specified that the first support section is integrally constructed with the air inlet component. Similarly, alternatively or supplementarily, it can be specified that the second support section is integrally constructed with the air guide channel. Depending on the material used, integralness can also be achieved by molding the corresponding support section or by spraying onto the corresponding component. Therefore, it is not mandatory that the support section be made of the same material as the component in which it is located. This particularly allows for the use of materials especially suitable for forming pivot supports for air conditioning blades, while the remaining material of the corresponding component, i.e., the air inlet component or the air guide channel, can be designed to be particularly suitable for conveying air.

[0012] According to the invention, air conditioning via the at least one air conditioning slat should be automatable. To this end, the air guiding device according to the invention includes a drive device coupled to at least one air conditioning slat, which, in operation, pivots the at least one air conditioning slat. This drive device (which may be, for example, an electrically operated actuator) can then be triggered by a control device in the vehicle. Therefore, the position of one or more air conditioning slats can be changed automatically or intentionally by the driver.

[0013] According to the invention, the air inlet component has a first drive device retaining section and the air guide channel has a second drive device retaining section. In this configuration, the drive device is thus housed between the first and second drive device retaining sections. This significantly simplifies installation because a separate retaining device is not required, and the drive device can be easily installed when assembling the air guide device.

[0014] According to a preferred embodiment, the drive unit is fixed to the air inlet component and / or the air guide channel. This saves structural space and a separate holding device for the drive unit, which in turn reduces the number of required components. Attached Figure Description

[0021] exist Figure 1 In the figure, the air guiding device according to the invention is indicated by reference numeral 1. Because it involves a component that can be used, in particular, at the front end of a vehicle, the direction of travel of such a vehicle is indicated by X, the vertical direction by Z, and the lateral direction perpendicular to X and Z by Y.

[0022] The air guiding device 1 according to the invention has an air inlet component 2 through which air 4 enters the air guiding device 1. After entering, the air passes through an assembly including at least one air conditioning vane 5. Air guiding is particularly possible in... Figure 3 plane B in Figure 1 As seen from the arrow in the cross-section. Figure 2 The example shown exemplarily illustrates four air conditioning flaps 5, but more or fewer such flaps may also be present. Preferably, a drive mechanism 6 is also provided, which ensures that the air conditioning flaps 5 can overlap. Preferably, the pivot axis of the air conditioning flaps 5 extends parallel to the transverse axis Y. Air 4 that has passed through the air conditioning flaps 5 enters the air guide channel 3 and further reaches the vehicle interior from there.

[0023] exist Figure 2 As shown in the exploded view, the drive device 6 is held by two drive device holding sections 2b and 3b. The first drive device holding section 2b is disposed on the air inlet component 2, and the second drive device holding section 3b is disposed on the air guide channel 3. Preferably, the drive device holding sections 2b and 3b are integrally constructed with components 2 and 3.

[0024] Furthermore, as shown herein, components 2 and 3 have flanges on their outer edges, which allow for mounting of the two components 2 and 3 by means of mutual contact of the end faces of the components and the flanges (preferably without the use of tools).

[0025] If these two components 2 and 3 are connected to each other, the drive unit 6 is simultaneously accommodated and fixed between sections 2b and 3b, a configuration particularly suitable for... Figure 4 plane A in Figure 1 This can be seen in the cross-section of the image.

[0026] Furthermore, the one or more air conditioning blades 5 are pivotally supported on the air guide device 1 by pivot support pins. For this purpose, as... Figure 5 As shown, the air inlet component 2 has a corresponding first support section 2a and the air guide channel 3 correspondingly has a second support section 3c. These two support sections 2a and 3c together form a corresponding pivot support device in which the pivot support pin 7 of the leaf 5 is accommodated. Section 2a also serves as a mating flange for section 3a of the air guide channel 3, which functions as a mating flange. These mating flanges 2a and 3a may also be constructed with a seal between them or be inherently sealing. For example, corresponding sealing lips may be installed or molded onto components 2 and 3 respectively.

[0027] Therefore, the air guiding device 1 described above can achieve corresponding air guiding by means of the air conditioning blades 5 in a manner that saves a lot of components.
