Description

Technical Field

[0001] This invention relates to a deflector or similar functional element for a windshield wiper device for motor vehicles. Background Technology

[0002] As already known from DE8716154U1, there is an attachment for a windshield wiper (Scheibenwischer, sometimes also called a windshield wiper), which has a flow guiding function. The attachment is made of plastic in an extrusion process and includes a receiving portion for the wiper bar of the windshield wiper device for securing the wiper arm. Furthermore, the attachment includes a receiving portion for the hose of the windshield wiper device. Summary of the Invention

[0003] The objective of this invention is to provide a wind deflector (sometimes called a baffle) or similar functional element of the type mentioned at the beginning, which can be particularly suitably fixed to the corresponding wiper arm of a windshield wiper device.

[0004] The task described herein is solved by a flow guide or similar functional element.

[0005] The air guide or similar functional element according to the invention is characterized by a receiving portion for fixing to a structural element of the wiper arm of a windshield wiper device, particularly the wiper bar. To create an air guide that can be particularly suitably fixed to a structural element of the wiper arm, particularly the wiper bar, according to the invention, the air guide comprises at least two parts that are assembleable and engageable in a separate state to a structural element of the wiper arm, thereby allowing the air guide to be arranged at a structural element of the wiper arm of the windshield wiper device. According to the invention, the air guide or functional element is thus designed in multiple parts, and multiple components are assembled and fixed by engaging with structural elements of the wiper arm, particularly the wiper bar. This has, for example, the advantage that other forms of structural elements of the wiper bar or wiper arm do not necessarily have a constant and straight orientation, but the air guide can, for example, also be arranged in the bending area of ​​the wiper bar. Furthermore, it is possible to design the corresponding structural elements used to secure the diffuser to the wiper arm, particularly the receiving portion at the wiper bar, to be made of corresponding hard plastic parts, which would achieve a very stable and rigid connection of the diffuser to the wiper arm. Moreover, such components of the diffuser can be manufactured extremely simply and cost-effectively.

[0006] In another embodiment of the invention, it has been shown to be advantageous that the deflector can be fixed to the wiper bar of the wiper arm of the windshield wiper device. The wiper bar allows for a particularly suitable and cost-effective fixation of the deflector.

[0007] Another advantageous embodiment of the invention is configured such that the receiving portion or receiving channel in which another structural element, the wiper bar or wiper arm, is separated by two parts of the flow guide. This suitable separation of the receiving portion or receiving channel allows for easy assembly of the flow guide at the wiper arm. Separating the flow guide into at least two parts has a particular advantage here, allowing the flow guide to extend through the bending area of ​​the wiper bar and thus be suitably assembled therein.

[0008] Furthermore, it has been shown to be advantageous that the windshield cleaning device is integrated into the deflector. This allows for the provision of a deflector with corresponding dual functions.

[0009] In another embodiment of the invention, the windshield washer fluid device is integrated into one of the two parts of the deflector. This has a particular advantage that, in the case of the two parts being joined, the components of the windshield washer fluid device that guide the cleaning fluid do not necessarily have to be joined to each other, which would result in structural redundancy or, if necessary, sealing problems. However, it should be noted within the scope of the invention that, if necessary, the windshield washer fluid device can also be disposed in both parts of the deflector.

[0010] Furthermore, it is advantageous that the two parts of the flow guide are connected to each other via a film scharnier or similar connecting element. This allows the two parts to be joined together particularly easily.

[0011] Another advantageous embodiment of the invention is configured such that the two parts of the flow guide can be connected to each other via a fixing device. The fixing device functions in a closed manner, allowing the two parts to be connected to each other in a simple way. If necessary, the fixing device can also be designed to be releasable, enabling the flow guide or functional element to be subsequently removed from the wiper arm.

[0012] In this regard, it has been further shown that the fixing device for stopping the guide at the structural element of the wiper arm, especially the wiper bar, includes a corresponding stopping device. Thus, in the case of joining the two parts, not only is it achieved to fix the guide or functional element to the corresponding structural element of the wiper arm, especially the wiper bar, but also axial movement is stopped.

[0013] Finally, it has been shown to be advantageous that the corresponding locking elements for connecting the two parts are constructed from the elastic plastic parts of the diffuser, and the corresponding stop protrusions are constructed within the plastic parts of the diffuser. The locking elements can thus be easily connected to each other by being formed from the corresponding elastic plastic parts that are ultimately needed. Conversely, the stop protrusions, made of hard plastic parts, ensure particularly stable stopping of the diffuser at structural elements or the wiper bar, so as to prevent movement along the wiper bar, etc. Attached Figure Description

[0023] The embodiments described below are preferred embodiments of the present invention. In these embodiments, the described portions of the embodiments each present an individual feature of the invention that should be considered independently of each other, and each feature also extends the invention independently of each other. Therefore, the disclosure should also include features different from the combination of features shown in the embodiments. Furthermore, the described embodiments can also be supplemented by other features among the features already described in the present invention.

[0024] In the accompanying drawings, the same reference numerals indicate elements that have the same function.

[0025] Figure 1a , 1b Figure 1c shows, in a corresponding perspective view, the assembly process for arranging and securing the functional element 1, which will be explained in more detail below, to the wiper arm 2. The wiper arm 2 and the functional element 1 are shown here... Figure 1aThe first part is shown in a decomposition.

[0026] It is particularly evident here that the wiper arm 2 includes a wiper bar 3, which is angled in the bending region 4. On the side opposite the free end 5, the wiper bar 3 is fixedly connected to a spring box 6, which is at least substantially rectangular in cross-section in the connection region 7 and is coiled to the wiper bar 3, which is also at least substantially rectangular in cross-section. The spring box 6 is hingedly connected via a support opening 8 to a lever element (sometimes referred to as a retainer) of the windshield wiper device, which is itself anti-rotationally connected to the drive shaft of a mating drive motor. About an axis formed by a support pin 8, the wiper arm 2 is pivotable relative to the mating lever element against the spring force of a spring element, which itself can engage with a spring receiving portion 9 at the corresponding end of the wiper bar 3, so as to press the wiper arm 2 or the mating wiper blade against the surface of the windshield, for example, in the operating position.

[0027] The functional element 1 has a first sub-region 10 and a second sub-region 11 integrally constructed with the first sub-region. A continuous receiving channel 12 for the wiper bar 3 is provided in both the first and second sub-regions. The receiving channel 12 here, in terms of cross-section, at least substantially matches the generally rectangular cross-section of the wiper bar 3, which has at least substantially uniform cross-section along its entire length. Therefore, the receiving channel 12 also has substantially uniform cross-section along its entire length within the functional element 1.

[0028] As shown in the overview below Figure 1b and 1c As can be seen, the functional element 1 can therefore be inserted or pushed onto the wiper bar 3 from its free end 5 until the end 13 of the first sub-region 10 of the functional element 1 is at least substantially flush with the connection region 7 of the spring box 6. In order for the functional element 1 to be inserted onto the wiper bar 3 up to the spring box 6, the functional element 1 in the first sub-region 10 (starting from the end 13) is made of an elastic material, such as a corresponding plastic, at least across the bending region 4. With such a soft, elastic material, it is also conceivable that the connection region 7 of the spring box 6 extends cylindrically from the end 13 of the sub-region 10 of the functional element 1.

[0029] The end 13 of sub-region 10 extends from a conduit 14, through which windshield cleaning fluid can be supplied to functional element 1 in a manner further described below. Therefore, at least one supply channel 15 for windshield cleaning fluid is constructed within the conduit 14, through which windshield cleaning fluid can be supplied to functional element 1 in a manner further described below. The supply channel 15 also extends through sub-regions 10 and 11 of functional element 1. Therefore, a windshield cleaning device 16 or a portion thereof is constructed in functional element 1, such that, in this case, the wiper arm 2 is a so-called wet wiper arm. This means that windshield cleaning fluid can be applied to the windshield to be cleaned, particularly the front windshield of a motor vehicle, via a nozzle carried by the wiper arm 2, by means of a windshield wiping device. The end of the conduit 14 of functional element 1 is here connected to the windshield cleaning device for windshield cleaning fluid along with a mating pump via a channel assembly (not shown further). The aforementioned passageway assembly is typically located in the front space or engine compartment of a motor vehicle. For example, especially by... Figure 1c As can be seen, the conduit 14 extends further under the wiper rod 3 into the interior of the spring box 6 in the current case.

[0030] In addition, overview Figures 1a to 1c It can be seen that the movement of functional element 1 onto the scraper rod 3 is such that the scraper rod, as it is... Figure 1c As can be seen in the final assembled position of functional element 1, it extends from the receiving channel 12 over a significant length region at the free end 5. This, in turn, means that functional element 1 is connected via the receiving channel 12 to the length region of the scraper bar 3 spaced apart from the free end 5 of the scraper bar 3, with sub-regions 10, 11.

[0031] In other words, the free end 5 extends out of the sub-region 11 of the functional element 1 or from the receiving channel 12.

[0032] The windshield cleaning device 16 integrated into the functional element 1 currently includes a channel system having corresponding channels integrated into the functional element 1, the channels leading to different nozzles through which windshield cleaning fluid can be applied to the windshield to be cleaned or wiped, or to a matching wiper blade, which will be explained in more detail below.

[0033] Thus, the windshield cleaning device 16 first includes two outer circular nozzles 17 and 18, through which the wiper blade is applied to a region near its outer circumference, i.e., a region where the wiper blade passes through the maximum radius of the surface to be wiped. Outer circular nozzle 17 covers the area closer to the functional element 1, and outer circular nozzle 18 covers a region further away from the functional element 1 but closer to the outer circumference of the corresponding wiper blade.

[0034] Furthermore, the windshield cleaning device 16 includes a plurality of, currently five, intermediate nozzles 19, all of which extend at least substantially in a row along the extension direction of the functional element 1. The respective nozzles 19 are respectively positioned to mating protrusions 20 projecting from the functional element 1 or from the wiper arm 2 toward the windshield to be wiped and cleaned, as described below. Finally, the windshield cleaning device 16 includes at least one inner circular nozzle 21, via which cleaning fluid is supplied to the wiper blade of the wiper arm 2 in the following region of its inner circle, in which the wiper blade passes through the shortest radius of its corresponding wiping surface during wiping. All nozzles 17, 18, 19, and 21 can be adjusted such that, upon initiation of movement—that is, in the case of the front windshield—the nozzles apply cleaning fluid at corresponding intervals to the windshield, particularly the front windshield, before the wiper blade moving there, as the respective wiper arm 2 moves upward. If necessary, windshield cleaning fluid can also be applied directly to the wiper blade.

[0035] In addition to the integration of the windshield cleaning device 16, the functional element 1 includes an additional function of air diversion. Therefore, the functional element 1 is configured as an air diverter 22 in the present case and includes a diversion profile 23 on the front or upper side at least substantially away from the nozzle 19 and the wiper arm 3, so as to achieve a particularly suitable overflow of air that normally flows from the front to the corresponding wiper arm 2 or the corresponding wiper blade.

[0036] The current functional element 1 is therefore configured as a deflector 22 and integrated for the windshield cleaning device 16. However, within the scope of this invention, it can be considered that the functional element 1 may also perform only one of these two functions.

[0037] Figures 2a to 2c Shown in corresponding local and perspective subviews Figures 1a to 1c Functional element 1 of the embodiments described herein. (Hereinafter by...) Figure 2a In particular, the receiving channel for the scraper bar 3 and the third sub-region 24 of the functional element 1 can be seen, which is also a single-piece construction with sub-regions 10 and 11. Figure 2b and 2cThis shows the position of the functional element 1 when it is fully inserted into the wiper arm 3. In this position, the third sub-region 24 of the functional element 1, particularly with respect to the insertion position of the wiper arm 2 at its front and lower sides, covers the free end 5 of the wiper arm 3. Furthermore, it can be seen that the wiper arm 3 is arranged in a recessed manner relative to the sub-region 24.

[0038] Through Overview Figure 2a and 2b Together with Figure 2c Furthermore, it can be seen that, in the current case, functional element 1 is stopped at the scraper bar 3 of the scraper arm 2 by means of fixing device 25 along the extension direction of receiving channel 12. The stop is achieved in the current case by means of tab 26, which is pivotally arranged at functional element 1 via film hinge 27. If tab 26 is inserted into the locking receiving portion 29 provided for this purpose in the region of receiving channel 12 by means of locking element 28, the locking element 28 also engages with the groove 30 ( ) in the scraper bar 3. Figure 1a The functional element 1 is engaged. This results in a certain degree of axial stop at the wiper rod 3, so that the functional element 1 stops in a corresponding position after being pushed onto the wiper rod 3.

[0039] Fixing device 25 in Figure 3a and 3b The corresponding cross-sectional view of the arrangement of the functional element 1 at the wiper rod 3 further illustrates its mode of operation. In particular, it can be seen how the locking element 28 is axially stopped on the side of the contact piece 26 within the locking receiving part 29 or in the groove 30 of the wiper rod 3.

[0040] In addition, from Figure 3a and 3b As is evident from the different shading lines, functional element 1 is currently manufactured as a plastic part using a two-component method, such as a two-component injection molding method. Particularly noticeable here is that the receiving channel 12 is formed by a rigid component 31 in the region of the fixing device 25. Similarly, the corresponding channels for guiding the cleaning liquid in the second and third sub-regions 11, 24 of functional element 1 are formed by the same rigid component 31, at least in the regions of the corresponding nozzles 17, 18, 19, 21. In between, a portion may also be formed by a flexible plastic component 32, which, as previously explained, also forms the first sub-region 10 and the tubing component 14. This can be achieved by… Figure 3a and 3b As can be seen, the flow guide profile 23 of the functional element 1 is also constructed via the soft component 32. Components 31 and 32 are here specifically constructed to be UV resistant so as to maintain durability accordingly.

[0041] exist Figure 4aand 4b In the diagram, an alternative embodiment of functional element 1 is shown in a corresponding perspective view. This functional element 1 is substantially the same in design and function as that according to the first embodiment described, so only the differences should be discussed below. Essentially, the difference in this functional element 1 is that, in this functional element, the first sub-region 10, which extends between the second sub-region 11 and the connection region 7 of the spring box 6, is not provided. Instead, functional element 1 terminates with an end 33 spaced apart before the bending region 4, and thus terminates with a significant distance before the connection region 7 of the spring box 6. The conduit 14 of functional element 1 thus extends significantly in length, without the additional covering of the scraper rod 3, from below or inside into the spring box 6, from which further connections are made for supplying cleaning fluid.

[0042] Depending on how short the functional element 1 is constructed, one or more corresponding inner circular nozzles 21 may be omitted in some embodiments if necessary. Such a design is implemented, for example, in compact vehicles where swiping or cleaning of a relatively small windshield surface is required. This solution is also necessary on the corresponding passenger side of larger windshields. Furthermore, the windshield cleaning device 16 integrated into the functional element 1 has a connection with the already combined… Figures 1a to 3b The described embodiments are at least substantially the same design. However, a smaller number of intermediate nozzles 19 may be provided depending on the length of functional element 1, or especially sub-regions 11 and 24. In the current embodiment, a locking element 28 can also be seen, by means of which functional element 1 can be stopped after being inserted into the scraper rod 3.

[0043] Finally in Figure 5a and 5bThe image shows, in a corresponding perspective view, the assembly of the wiper blade 34 at the corresponding free end 5 of the wiper rod 3, which extends from the receiving channel 12 of the functional element 1. The wiper blade 34 here includes a wiper blade element 35 at which a base in the form of a slider 36 is fixed. This slider 36 is hingedly connected to an adapter 37, allowing the wiper blade element 35, together with the slider 36, to pivot relative to the adapter 37 within certain limits. The adapter 37 includes a receiving portion 38, which is at least partially open in this case, allowing the adapter 37, or thus the entire wiper blade 34, to be inserted into the free end 5 of the wiper rod 3 via said receiving portion. For this purpose, the receiving portion 38 (constructed as a plug-in receiving portion) is compatible with the cross-section or shape of the wiper rod 3. After the adapter 37 is inserted into the free end 5 of the wiper bar 3 over a certain length region via the receiving portion 38, the locking device 39 engages, comprising corresponding locking elements not only on the side of the adapter 37 but also on the side of the wiper bar 3. The locking device 39 may, for example, include a locking pin or the like on the side of the adapter 37, which engages with a locking recess on the side of the free end 5 of the wiper bar 3. The locking device 39 can be released here by means of an actuating element 40 in the form of a button or the like, which in this case must be pressed toward the wiper blade element 39.

[0044] In its locked position, the actuating element 40 passes through a through-hole 42 within the sub-region 24 of the functional element 1. Thus, in the locked position of the locking device 39, the actuating element 40 is at least substantially arranged within the through-hole 41 and can therefore be actuated from the front and outside to remove the squeegee blade 34 from the free end 5 of the squeegee rod 3.

[0045] Since the functional element 1 is fixed at the wiper rod 3 in a length region spaced apart from the free end 5, and the adapter 37 of the wiper blade 34 is fixed at the free end 5 of the wiper rod, the functional element 1 and the wiper blade 34 are arranged and fixed at the wiper rod 3 completely independently. This has the advantage that the wiper blade 34 can be removed and replaced, for example, from time to time, completely independently of the functional element 1, without affecting the operation of the functional element 1. In particular, it should be considered that even when the adapter 37 is removed, but the functional element 1 remains at the wiper rod 3, not only is the flow guiding function of the functional element 1 fully maintained, but also the windshield cleaning function of the functional element is fully maintained. Unlike other systems where the flow guiding device or part of the windshield cleaning device is not removed and, for example, cleaned when the wiper blade 34 is replaced, this raises corresponding economic and durability issues. Conversely, this provides a system in which the connection of the wiper blade 34 and the connection of the functional element 1, as well as the execution of the functions implemented by the functional element 1, are completely independent of each other.

[0046] In addition, other components can be integrated into functional element 1. In particular, a heating device for the windshield washer system can also be integrated together. Here, the advantages already described in conjunction with the windshield washer system are also obtained.

[0047] exist Figure 6a and 6b Another alternative embodiment of functional element 1 is shown in the corresponding perspective view. The functional element 1 is substantially the same as that described in the first embodiment in terms of design and function; therefore, only the differences will be discussed below. Essentially, the difference in functional element 1 is that it consists of two parts 42 and 43, which are connected to each other in a single piece within a region 44 by means of a thin-film hinge. If necessary, variations of a completely two-piece or multi-piece design can also be conceived here.

[0048] Overview Figures 8a to 8c (These figures show corresponding cross-sectional views through the functional element 1 or the wiper rod 3), where it can be seen how the two parts 42, 43 or the functional element 1 are generally arranged and fixed at the wiper rod 3. According to... Figure 6a Or 8a, with the functional element 1 pushed and / or inserted into the scraper rod 3 when the portions 42, 43 are open, until the scraper rod 3 (as it is made of, in particular, by) Figure 8bAs can be seen, it is arranged in its provided receiving channel 12, which is constructed similarly to the receiving channel 12 according to the first two embodiments. In other words, the two parts 42, 43 of the functional element 1 or the flow guide 22 can be assembled at the scraper bar 3 of the scraper arm 2 in a separate state.

[0049] Immediately thereafter, the two portions 42, 43 can then pivot and engage with each other about an axis formed by a membrane hinge 44 or the like, until, in the present case, the portions 42, 43 are connected to each other on the side opposite to the membrane hinge 44 by means of a fastening device 45. The fastening device 45 here includes one or more locking elements 46 at portion 43, the locking elements (such as those made of…) Figure 8c (As can be seen) It engages with one or more corresponding locking elements in the form of locking receiving parts 47. Thus, by engaging the two parts 42, 43, the deflector 22 is fixed to the structural element 3 of the wiper arm 2 of the windshield wiper device.

[0050] Furthermore, corresponding stop protrusions 48 and 49 are arranged at the two portions 42 and 43, the stop protrusions (as they are made of...) Figure 7 (As can be seen) it engages with the groove 50 in the wiper rod 3. The stop protrusions 48, 49, when acting together with the groove 50, thus act as an axial stop for the fixing device 45, so as to prevent the functional element 1 from moving along the extension direction of the wiper rod 3.

[0051] In the current configuration, the corresponding locking elements or locking receivers 46, 47 are configured to connect the two parts 42, 43 in the elastic plastic component 51 of the diffuser 22. Corresponding stop protrusions 48, 49 for fixing the functional element 1 to the wiper rod 3 are constructed in the rigid plastic component 52 of the diffuser 22.

[0052] The separate implementation of the functional element 1 with portions 42 and 43 provides the advantage that the functional element 1 can be easily fixed to the wiper rod 3, even if the wiper rod 3 has, for example, a non-linear orientation or a bent region 4. The functional element 1 can extend not only to the spring box 6 or to the connecting region 7 of the spring box, but also terminate at a distance from the connecting region 7. Currently, both portions 42 and 43 extend past the bent region 4 of the wiper rod 3 and out to the spring box 6.

[0053] In addition, especially by Figures 8a to 8cAs can be seen, in the foregoing embodiments, the functional element 1 is partially constructed of an elastic plastic component 51 and partially of a hard plastic component 52. The receiving portion or receiving channel 12, in the present case at least in sub-region 11, but also, for example, in sub-region 10, is constructed of hard plastic component 52, thereby achieving a particularly robust and reliable arrangement of the functional element 1 at the wiper bar 3. In other words, the receiving portion or receiving channel 12 is separated by two portions 42, 43 of the deflector 22.

[0054] Furthermore, in the current case, at least substantially all the components that guide the liquid in the windshield washer fluid device 16, namely, the supply channel 15 and the corresponding nozzles 17, 18, 19, 21, are made of hard plastic parts 52. The components that guide the cleaning liquid in the windshield washer fluid device 16 are thus implemented in a particularly stable and sealed manner. However, the windshield washer fluid device 16 here (as it is particularly made of...) Figures 8a to 8c (As can be seen) It is at least substantially fully integrated into the elastic plastic component 51.

[0055] Furthermore, in this embodiment, the windshield cleaning device 16 is integrated into only one of the two portions 42, 43 of the deflector 22. This is particularly advantageous due to the sealing performance, as the components of the two portions 42, 43 that guide the cleaning fluid do not need to be connected to each other.

[0056] In particular (regarding the placement of functional element 1 or deflector 22), surface 53 on its visible side is at least substantially entirely composed of resilient plastic component 51. This results in a particularly pleasing visual appearance and, moreover, provides functional element 1 that is particularly well protected from impacts, shocks, etc. The resilient plastic component 51 is preferably made of a UV-resistant material for durability. Furthermore, the resilient plastic component 51 has raised portions 54, which, for example, function as shock absorbers to protect functional element 1 or deflector 22 and the surface of the windshield to be cleaned.

[0057] Overall, it can be seen that a functional element 1 or a flow guide 22 is currently provided, which includes at least two parts 42, 43, which are assembleable and engageable in a separate state at a structural element 3 of the wiper arm 2, thereby allowing the flow guide 22 to be arranged at the structural element 3 of the wiper arm 3. This has the advantage, for example, that the wiper bar 3 or other forms of structural elements of the wiper arm 2 do not need to have a constant and straight orientation, but the flow guide 22 can also be arranged, for example, in the bending region 4 of the wiper bar 3. Furthermore, it is possible that the receiving portion or receiving channel 12 used to fix the flow guide 22 to the corresponding structural element of the wiper arm 2, especially the wiper bar 3, can be designed to be made of a hard plastic component 52, which again enables a very stable and rigid connection of the flow guide 22 at the wiper arm 3.
