Description

Technical Field

[0001] This invention relates to a wiper assembly for a glass wiper with a rinsing function. More particularly, this invention relates to a wiper assembly having a particularly advantageous connection and fixation of the wiper blade assembly to the wiper arm, as well as a liquid delivery device. Background Technology

[0002] Windshield wipers for vehicles are known in a variety of embodiments. It is also known here that the windshield wipers are equipped with a rinsing function so that cleaning fluid can be directly rinsed through the wipers onto the windshield of the vehicle to be cleaned.

[0003] In this regard, a wiper blade device has been proposed, which includes a wiper blade adapter, at least one baffle unit and at least one flushing unit, the at least one flushing unit having at least one cleaning fluid channel unit, the at least one cleaning fluid channel unit at least partially forming a main longitudinal channel. Summary of the Invention

[0004] This invention relates to a windshield wiper assembly for a vehicle, comprising a wiper arm and a wiper blade assembly, wherein the wiper blade assembly includes a wiper strip, a deflector plate thereon, and a wiper blade that can be secured to the wiper strip or the deflector plate, and wherein the wiper blade assembly further includes an adapter having a liquid inlet and two liquid outlets for conducting liquid introduced into the liquid inlet through the liquid outlets into a liquid channel of the deflector plate, wherein the adapter is constructed in a multi-component manner such that the adapter has a first component having the liquid inlet, a first outlet region, and a second outlet region, wherein the first component further has deflection geometry for conducting liquid entering the liquid inlet to the first outlet region and the second outlet region, and wherein the adapter further includes a second component and a third component, wherein the second component closes the first outlet region and has the first liquid outlet, and wherein the third component closes the second outlet region and has the second liquid outlet.

[0005] This type of wiper assembly also allows for particularly easy and reliable assembly and disassembly of the wiper blades.

[0006] The aforementioned wiper assembly is particularly helpful for the use of windshield wipers for vehicles, especially motor vehicles. The wiper assembly includes a wiper arm and a wiper blade assembly. The wiper arm is particularly useful for the mechanical connection of the wiper blade assembly in a motor vehicle, and is specifically designed for: a swingable fastening adjacent to the vehicle's glass. Furthermore, the wiper arm can be driven by a windshield wiper motor in a manner known per se. The wiper blade assembly, in particular, is a portion of the wiper assembly or the windshield wiper that slides along the vehicle's glass guided by the wiper arm.

[0007] Furthermore, the wiper assembly includes a wiper strip, a baffle plate that can be fastened thereto, and a wiper blade that can be fastened to the wiper strip or the baffle plate. The wiper strip can be made of, for example, metal and can provide mechanical stability to the wiper assembly. Furthermore, the wiper strip can be used to hold the baffle plate and, if necessary, hold the wiper blade. The baffle plate is used in a manner known per se to press the glass wiper against the glass at high speeds, thereby achieving good wiping results. Furthermore, the baffle plate can have channels for guiding cleaning liquid, as this aspect will be described in more detail below. The wiper blade particularly includes a rubber lip that slides directly along the glass and thus removes liquid from the glass. The rubber lip or the wiper blade can be fastened to the baffle plate or also to the wiper arm.

[0008] Regarding the operation of the glass wiper or the wiper assembly, it is preferable to design the wiper assembly such that a cleaning liquid, such as water mixed with detergent, is applied to the glass. This ensures that dirt is cleaned from the glass particularly effectively and quickly. Because by spraying the cleaning liquid onto the glass with the wiper assembly, the cleaning liquid can be sprayed precisely and comprehensively in the desired location where the glass wiper cleans the glass. Therefore, the application of cleaning liquid to the glass is made more reliable by the wiper assembly.

[0009] To achieve this, the wiper blade assembly is configured with an adapter having a liquid inlet and two liquid outlets, so that liquid introduced into the liquid inlet is conducted through the liquid outlets to the liquid channels of the baffle. Therefore, a channel geometry or deflection geometry is provided within the adapter, allowing the cleaning liquid to be conducted from the liquid inlet to the liquid outlet. Here, the channel geometry can be designed, for example, by adapting the corresponding channel size proportions, so that the cleaning liquid is consistently distributed along the length of the baffle or at least a portion of the wiper blade, ensuring consistent water discharge along the length of the wiper blade and thus ensuring a consistent cleaning result to an equal degree.

[0010] Furthermore, the liquid inlet and the liquid outlet can have corresponding connectors for coupling with adjacent components.

[0011] Furthermore, the adapter is configured as a multi-component unit. This multi-component configuration is such that the adapter first has a first component having the liquid inlet, a first outlet region, and a second outlet region. Here, the outlet region is a region of the adapter that is located adjacent to, and particularly close to, the corresponding outlet, such as, for example, the adapter's connector.

[0012] The first component further includes a deflection geometry by means of which the cleaning liquid conducted into the liquid inlet can be conducted to the liquid outlet, or initially to the outlet region. Since the liquid inlet is preferably arranged such that the cleaning liquid flows into it at an angle rather than parallel to the main axis of the adapter, the conduction of the liquid involves a deflection, which is made possible by the deflection geometry. Therefore, the deflection geometry is used to conduct the cleaning liquid from the liquid inlet to the liquid outlet in an appropriate manner.

[0013] The adapter further comprises a second component and a third component. The second component encloses the first outlet region and has a first liquid outlet. The liquid outlet is, in particular, an opening and a component capable of connecting, in particular, to a liquid channel in the baffle plate. Correspondingly, the third component is provided: it encloses the second outlet region and has the second liquid outlet. The liquid outlet is again, in particular, an opening and a component capable of connecting, in particular, to a liquid channel in the baffle plate.

[0014] The multi-part design of the adapter, as previously described, particularly leads to advantages over the prior art. This is because the adapter can be highly adaptable to different windshield wiper designs and especially to different deflector geometries. Essentially, the adapter body can be used in standard size, and only the second and third parts are adapted to the windshield wiper environment, such as by adapting to the size, geometry, and / or position of the exhaust outlet.

[0015] This enables widespread applicability through the adaptation of the second and third components.

[0016] Furthermore, it is possible to prevent defective parts during production when necessary. Because if damage occurs, for example, only within the scope of the first, second, or third component, then only those components can be replaced. This can save costs during manufacturing.

[0017] Furthermore, it is feasible to equip at least one of the second and third components, for example, the second and third components, with a liquid nozzle for spraying liquid in relation to use, in order to further improve the cleaning results. This thus enables further improvement in versatility and adaptability on top of the already improved wiping results.

[0018] Preferably, the second component and the third component are fastened to the first component by a non-detachable connection. By providing a non-detachable connection, exceptionally high mechanical stability can be achieved when necessary. Furthermore, the risk of leakage is kept exceptionally low. This reduces the risk of damage to the desired long-term stable operation compared to solutions from the prior art. Moreover, this design resists unintentional detachment of the second component or the third component from the first component.

[0019] Examples of this type of non-detachable connection include, for example, snap-fit ​​connections, welded connections, or adhesive connections. These types of connections provide a secure and reliable permanent fixation, are simple in nature, and can be implemented using conventional methods. Furthermore, adhesive or welded connections are particularly suitable for minimizing the risk of leakage.

[0020] Furthermore, it is preferable that the adapter has a main axis extending from the first liquid outlet to the second liquid outlet, and the deflection geometry extends adjacent to both the first and second liquid outlets along the main axis, and the deflection geometry includes at least one other region in which the deflection geometry extends parallel to but differently from the main axis. This design also allows for liquid deflection within a small structural space, enabling efficient and desired distribution of the cleaning liquid even in a limited space.

[0021] Furthermore, it is advantageous that the second and third components have liquid channels entirely located on the main axis. In other words, the cleaning liquid is no longer deflected in the second and third components, but is conducted along the axis passing through them. This enables a particularly simple structure for the second and third components. Moreover, the second and third components can be designed with minimal space requirements.

[0022] Preferably, the wiper assembly has a connector that can be pivotally fixed at the adapter, and the connector has a wiper arm receiving portion in which the wiper arm can be fixed. In this design, the wiper blade assembly is fixed to the wiper arm, and thus the windshield wiper is installed. Here, it is feasible in a simple manner that the wiper arm is pushed into the wiper arm receiving portion and, particularly by means of a detachable fixing device, such as being fixed at the connector or the adapter.

[0023] For example, it is preferable that the wiper arm is secured within the wiper arm receptacle by a spring-loaded retaining element. For instance, when the wiper arm is pushed into the wiper arm receptacle, the retaining element can move against the spring force via the wiper arm or its fixed area, and when the wiper arm is in its fixed position, a correspondingly designed retaining geometry allows the retaining element to return to its fixed position by the spring force. In this position, the retaining element can lock the wiper arm to prevent it from leaving the wiper arm receptacle.

[0024] This type of design particularly provides a retaining device that reliably prevents the risk of unintentional detachment of the wiper blade assembly. Furthermore, the connection can be easily disengaged to remove the windshield wiper. To disengage the retaining device, for example, the spring-loaded retaining element can be pressed out of the fixed geometry of the wiper arm by pressing a button against the spring force. The button can be, for example, a component of the connector.

[0025] Furthermore, it is preferable that the fluid inlet of the adapter is constructed with a male connector. In this design, a hose can be pushed onto the connector, which further simplifies the structure and assembly or disassembly. It is also feasible that the fluid delivery device, such as a hose, is connected to the adapter via a corresponding adapter. The adapter can be connected to the connector, fixed at the connector, or completely independent of the connector.

[0026] Furthermore, it is preferable that the deflector has a large number of liquid nozzles for spraying liquid. This allows for particularly uniform application of the cleaning liquid to the vehicle's windshield, as the nozzles can be easily distributed on the deflector. This also allows for a simple structure or design of the wiper blade device. As described above, it is particularly preferred that the deflector carries a channel for distributing the cleaning liquid, the channel being connected to the adapter or the adapter's liquid outlet.

[0041] exist Figure 1 The design of the wiper device 10 according to the present invention is shown in the figure. Figure 1 The wiper assembly 10 is shown in either its operational or assembled state, and Figure 2 and Figure 3 The wiper assembly 10 is shown in more detail, either as a single component of the wiper assembly or in an exploded view.

[0042] The wiper device 10 is particularly used for windshield wipers of vehicles and can be installed near the glass on the vehicle itself.

[0043] It is shown that the wiper assembly 10 includes a wiper arm 12 and a wiper blade assembly 14. The wiper blade assembly 14 is further particularly capable of... Figure 2 The wiper assembly is identified as having a wiper blade 16, a baffle plate 18 thereon for fastening, and a wiper blade 20 for fastening to either the wiper blade 16 or the baffle plate 18. Furthermore, the wiper assembly 14 is provided with an adapter 22 having a liquid inlet 24 and two liquid outlets 26, 28, so that cleaning liquid introduced into the liquid inlet 24 is conducted through the liquid outlets 26, 28 to the liquid channel 30 of the baffle plate 18. This aspect is shown in more detail in the following figures.

[0044] Figure 3 The basic structure of the wiper assembly 10 is also shown. It is shown in detail that the adapter 22 can be pushed onto the wiper blade 16. Furthermore, the adapter 22 can engage or be welded to the wiper blade 16. On both sides of the adapter 22, dual-part guide vanes 18 can also be pushed or engaged onto the wiper blade 16 and contact the adapter 22, as this aspect should be illustrated by the arrows.

[0045] Figure 4 A cutaway detailed view of the adapter 22 with the liquid outlets 26, 28 is shown, which are respectively connected to components of the baffle 18 so that cleaning liquid can flow from the adapter 22 into the liquid channel 30 of the baffle 18, as this aspect should be illustrated by the arrows.

[0046] This is one aspect Figure 5 It is shown in detail in Figure 5 The image shows a side view of the deflector 18, which has a liquid channel 30 disposed therein, the liquid channel being connectable to the liquid nozzle of the deflector 18 and to the liquid outlet 28 of the adapter. A fastening geometry 19 is also shown, in which the wiper blade 20 is fastened.

[0047] In addition Figure 6 and Figure 7The diagram shows that the adapter 22 is constructed in a multi-part configuration, such that it has a first part 32 having the liquid inlet 24, a first outlet region 36, and a second outlet region 38. It further shows that the adapter 22 also has a second part 33 and a third part 34, wherein the second part 33 closes the first outlet region 36 and has the first liquid outlet 26, and wherein the third part 34 closes the second outlet region 38 and has the second liquid outlet 28. It is also shown that the second part 33 and the third part 34 are fastened at the first part 32 by a non-detachable connection, as shown in the figures, particularly by means of welding or bonding.

[0048] exist Figure 8 and Figure 9 The design of the adapter 22 or the first component 32 for guiding the cleaning liquid is shown in more detail in these figures. It is shown in these figures that the first component 32 further has a deflection geometry 40 for conducting or deflecting the liquid entering the liquid inlet 24 to the first outlet region 36 and the second outlet region 38. More specifically, the adapter 22 has a main axis 42 extending from the first liquid outlet 26 to the second liquid outlet 28, and the deflection geometry 40 extends adjacent to the first liquid outlet 26 and the second liquid outlet 28 within the main axis 42. Furthermore, the deflection geometry 40 includes at least one additional region 44 in which the deflection geometry 40 extends parallel to but differently from the main axis 42. Therefore, the cleaning liquid is redirected, particularly in the first component 32 of the adapter 22.

[0049] Conversely, the second component 33 and the third component 34 are configured to have liquid channels 44, 46 that are fully positioned within the main axis 42. In other words, the cleaning liquid flows through the second component 33 and the third component 34 without deflection.

[0050] It is also shown that the axis 66 defined by the liquid inlet 24 is at an angle to the main axis 40, and the angle can be approximately 10°.

[0051] In addition Figures 10 to 12The diagram shows that the wiper assembly 10 has a connector 48 that can be secured to the adapter 22. The connector 48 further includes a wiper arm receiving portion 50 in which the wiper arm 12 can be secured. In this regard, it is particularly preferable that the wiper arm 12 is secured in the wiper arm receiving portion 50 by a spring-loaded retaining element. To disengage the fixation, for example, the retaining element pre-loaded by the spring force can be pressed out of the fixing geometry of the wiper arm 12 by pressing the button 52 against the spring force, thus disengaging the fixation. For example, in... Figure 3 The fixed geometry is shown in the diagram. The button 52 can be, for example, a component of the connector 48, as this aspect is illustrated in... Figures 10 to 12 As shown in the diagram.
