Description

"Windscreen wiper and vehicle with windshield wiper"

The invention relates to a windshield wiper, a vehicle having a front hood, a windshield and a windshield wiper and a use of such a windshield wiper and methods that can be performed with such a windshield wiper.

From DE 29708554 U1 a housing for covering the rear window wiper of a motor vehicle is known. A fixed housing part is formed like a trough in the tailgate. The lid is fixedly connected to the wiper arm and, in the rest position of the wiper arm, is substantially flush with the housing opening. If the rear window wiper is put into operation, it must first be moved linearly along the drive axis of the windscreen wiper in order to leave the housing recess. The focus here is a protection of the wiper blade from dirt and a reduced air resistance.

In today's vehicles, the hood moves closer to the windshield. This has both aerodynamic reasons and pedestrian protection benefits. This results in designs with Unterhaubenwaschdüsen always unfavorable angular positions with respect to the spray angle. The tolerances resulting from adjustment of the nozzle and Fastening tolerances of the nozzle body result, are getting smaller. Depending on the construction, it is hardly possible to spray over the wiper blade.

Against this background, the present invention has the object to provide a construction in which the windshield wiper water can be better applied to the disc to be cleaned and / or the aerodynamics can be improved.

This object is achieved by the windshield wiper of claim 1 and the vehicle according to claim 9 and the use according to claim 12 and the method according to claim 13 and 14. Advantageous embodiments are given in the subclaims and the following description.

The invention is based on the idea of providing a cover covering at least one region of the wiper arm and / or at least one region of the wiper blade of a windscreen wiper arm on the wiper arm of the windscreen wiper and forming at least one windshield washer nozzle as part of this cover or fastening it to the cover. By attaching the cover to the wiper arm, the cover is moved with the wiper arm. By forming the nozzle as part of the cover, or by placing the nozzle on the cover, the nozzle is also moved with the wiper arm. This provides the ability to change the relative position of the nozzle relative to the disc and to bring the nozzle in advantageous for dispensing the windshield washer fluid positions. In particular, this creates the possibility of moving the nozzle over the vehicle window during a wiping operation, so that the wiping liquid can be applied over the entire wiping process in the vicinity of the wiper blade. In addition, the provision of the cover provides the opportunity to use as a cover for a trough of a vehicle having an upper opening which is bounded on one side by the edge of the front hood, which has the front hood at its end facing the windshield, and is bounded on the opposite side by a part of the windshield or by a part of a frame which holds the windshield. The windshield wiper according to the invention offers the possibility of a nozzle system protected by the cover. The cover can prevent damage, soiling and rapid freezing of the nozzle. The cover is attached to the wiper arm. In the majority of embodiments, the wiper arm is made so rigid that the wiping action it follows follows a fixed path. By attaching the cover to the wiper arm, it is thus possible to move the nozzle formed as part of the cover or nozzle attached to the cover along a fixed path. The wiper arm of the windshield wiper according to the invention preferably has a metal profile or a plastic profile. The metal profile or the plastic profile may have at least one linearly extending region. Embodiments are also conceivable in which the metal profile or the plastic profile has a first, linearly extending region and a second, linearly extending region. In this case, embodiments are conceivable in which the first linearly extending region merges via a bend region into the second, linearly extending region. The wiper arm may comprise a fastener and a hinge with which the metal profile or plastic profile is pivotally attached to the fastener.

In a preferred embodiment, one end of the wiper rod in the form of a hook engages in a suspension frame of a wiper blade.

The wiper blade may have a suspension frame, which is formed by two side cheeks of a central bracket.

The wiper blade may have a mehrgliediges support bracket system, which is constructed with mounted on a central bracket, lower brackets, of which at least some hold with a fastening in the form of claws at their ends a wiper strip on the head strip. The support bracket system and the spring rails enclosed in the associated head strip allow the wiper strip to be adapted to a curved windshield during wiping with a largely uniform contact pressure. This can be supported by the bias on a hinged joint by means of a tension spring. It is also conceivable to provide only a resilient head strip instead of a multi-member support bracket system. In alternative, simplified versions subordinate bracket, also called claw bracket and intermediate bracket omitted. In simple embodiments, the center bracket itself claws, with which he holds the wiper strip.

The wiper arm can be connected with its attachment part with a drive shaft which drives the wiper arm during the wiping movement. For this purpose, the fastening parts may have a receptacle which can be connected to one end of the drive shaft, for example a receptacle in an internal toothing, which can be placed on a toothed drive shaft.

Particularly preferably, the at least one nozzle for windshield washer fluid is a part of the main body or attached to the main body. In a preferred embodiment, the base body is an elongate base body which extends along a longitudinal axis. In a preferred embodiment, the maximum length of the base body in the direction of the longitudinal axis is at least about 1, 5 times, more preferably at least twice, especially preferably at least three times greater than the maximum width of the cover measured in a direction perpendicular to the longitudinal axis.

In a preferred embodiment, the cover has a smooth outer surface. A smooth outer surface is understood in particular to mean a surface which has no steps and / or from which no further elements protrude. Particularly preferably, the smooth outer surface is flat or curved. In a preferred embodiment, no nozzle is provided on the outer surface. The outer surface may be used as the surface facing out when the cover is used in a preferred embodiment to close the trough of a vehicle. A smooth outer surface provides aerodynamic benefits in such an application.

In a preferred embodiment, the outer surface of the cover is planar, the term "plane" meaning that the outer surface is in a plane, such an embodiment is particularly useful when the cover is located adjacent the windshield Extended substantially plan extending portion of a front hood to the windshield or when the trough in the rear window, the roof or in the region of a pillar of the vehicle or in the region of the door, tailgate or trunk lid of the vehicle is arranged, as far as the adjoining the trough It is also conceivable to give the outer surface of the cover a three-dimensional shape and to use the cover as a design element, for example to border the transition from one to the trough the component of the vehicle, such as the front hood, towards the window, for example, towards the windscreen, to use either as a design element or as an element to improve the aerodynamics. For example, the cover can also be part of the outer appearance of the A-pillar. Likewise, a three-dimensional shape of the outer surface can be used to form a spoiler that affects the contact pressure of the windshield wiper on the wiping wheel.

In a preferred embodiment, the base body has a peripheral edge on which a sealing lip is provided. When the cover is used in a preferred embodiment to close the trough of a vehicle, this sealing lip can be used to increase the tightness of the closure. In a preferred embodiment, the cover is made of metal or of a plastic. Conceivable here is in particular the production of integrated nozzles, channels, openings and cavities, which can be produced for example by injection molding in plastic. To avoid restricting the driver's view of the vehicle, the cover of the windscreen wiper may consist in particular of substantially transparent material, in particular plastic. Furthermore, the cover can be made in part of rubbery, elastic material, which can well seal the edges in the case of the rest position. The invention provides that at least one nozzle for washer fluid forms part of the cover or is attached to the cover. In the context of the invention, a "nozzle" is also understood to mean a hole For example, in the case of a liquid-conducting channel running in a component (for example the cover) in whose wall the hole is located, the wiping liquid can escape through the hole on a component (for example, the cover) attached hose, in the wall of which the hole is located, the wiping liquid leak through the hole.

There may be provided a plurality of holes, in particular at different points of the wall of the channel, or the wall of the tube, in particular at several in the flow direction of the wiping liquid through the channel, or seen through the hose successively arranged locations. The hole diameter can vary. By varying the hole diameter, for example, the exiting amount of liquid can be influenced. For example, holes that are closer to a lower portion of the disk during operation of the windshield wiper may be made larger, so that there will be more wiping liquid spread over the disk by the wind, while holes closer to an upper one Area of the disc can be made smaller to minimize wiper fluid loss when excess wiping liquid is carried by the wind over the upper frame of the disc. It is also possible to use the size of the hole to adapt the wiper fluid emerging from the hole, for example, to unify the pressure.

The nozzles may have rigid outlets, for example

a hole as a nozzle,

a nozzle as an insert in the bore,

- A nozzle as an insert that generates an oscillating fan beam or a non-oscillating fan beam. Likewise, the nozzle may have an adjustable insert. The setting can be adjusted directly with a tool from the outside or indirectly with a set screw. In a preferred embodiment, at least two, more preferably at least three, more preferably at least four, most preferably at least five, most preferably at least six, more preferably at least seven nozzle for washer fluid form part of the cover or are attached to the cover.

In the case of nozzles on both sides of the wiper blade, it is conceivable that the nozzles are controlled individually, in particular by a plurality of supplied to the windshield wiper hoses and / or electrical valves. For example, a spraying of the windshield is predominantly on the side of the wiper blade feasible, which points in the direction of movement, so that the rubber lip of the wiper blade remains at least substantially wetted by the wiper liquid. Further advantages for this concept of the so-called wet arm wiper, in which mainly the surface is wetted before the wiper blade, consist in the minimized obstruction of the driver, the protection of the wiper blade and the disc and in the optimal use of mop water, since the water is only passed there, where it is needed.

In one embodiment, the channels and / or tubes supplying the wiping liquid and the nozzles are located under the cover (on the side opposite an outer surface of the cover). The attachment of these elements can preferably be done on the cover, in particular with adhesive or latching attachment methods. Alternatively, the installation of the hoses on the wiper arm and / or the wiper blade is conceivable.

Fig. 10 section and perspective view of a nozzle for attachment to a fluid channel. In Fig. 1 is a section through the front portion of a vehicle 2 with a front hood 7 made of metal or plastic, a windshield wiper according to the invention 1 in a trough 7 and a windshield 3 is shown. The front hood 7 preferably terminates flush with the trough 8. Both components can be fastened to each other in particular by clamping or latching. The trough 8 is firmly connected to the front hood 7 opposite side with another component of the vehicle 2, in particular with the frame or the windshield 3 itself. The compound is preferably adhesive, wherein detent or clamping also represent possible realizations. The trough 8 or the gap between the windshield 3 and front hood 7 is at least substantially covered and filled by the windshield wiper 1. The cover 6 of the windshield wiper 1 preferably terminates flush with both outer edges of the trough 8, such that a predominantly smooth transition from the front hood 7 to the windshield 3 is provided, which offers aerodynamic advantages as well as minimizes risk of injury to pedestrians. Optionally, the cover 6 of the windshield wiper 1 closes the trough 8 tight to ensure maximum protection against contamination or driving noise.

In Fig. 2 is a sketch of the front view of a vehicle 2 with windshield 3 and front hood 7 with 2 adjacent windshield wipers 1 according to the invention shown. On the left side of Fig. 2, the windshield wipers 1 are not in operation and are therefore in their rest position. It can be seen that the associated covers 6 of the windshield wipers 1 at least partially cover the area between the front hood 7 and the windshield 3. Furthermore, mutually complementary edges on the joint of the two covers 6 in plan view can be seen. The right part of Fig. 2 shows the windshield wipers 1 in the operating state and about 90 ° rotated windscreen wiper 1, which leave an open trough 8. The limitation of the view during the wiping process is reduced in particular by foldable covers of the windshield wiper and / or a cover made of partially transparent materials.

In Fig. 3, the plan view of a windshield wiper 1 according to the invention with a wiper arm 4, a wiper blade 5 and a cover 6 is shown schematically. It shows a relative to the wiper arm 4 wide cover 6, which over the wiper blade. 5 and wiper arm 4 is attached. Preferably, the cover 6 is connected to the wiper arm 4 connected via a reversible mounting option such as a clamp, screw or a quick release fastened. The outer contour of the cover 6 is slightly sickle-shaped here on the side facing away from the wiper arm 4. This allows the smoothest possible driving in the wiper 1 in the rest position. In this case, the tip of the cover 6 preferably covers a part of the adjacent windscreen wiper 1. In the viewing direction of Fig. 3, the cover 6 at least 70% of the maximum cross section of the wiper blade in this direction and at least 70% of the maximum cross section of the wiper arm in this direction from.

4 shows a side view of a windshield wiper 1 according to the invention with a wiper arm 4, two hoses for supplying windshield washer fluid, nozzles and a cover 6. The cover 6, which is designed to be largely planar, can be seen, which holds two hoses or fluid channels on the underside which windscreen wiper water to the nozzles. The nozzles can be located along the entire windscreen wiper 1.

5 shows a side view of a windshield wiper 1 according to the invention with a wiper arm 4, a wiper blade 5 and a folded cover 6 in the operating state. In this embodiment, the cover 6 has a single fold, which is typically at least substantially parallel to the wiper arm 4 and is more or less centered in the transverse direction. The material may be made of metal, preferably plastic, in particular transparent plastic. Also conceivable is a shape memory material, which folds up for operation and is unfolded in the rest position. A folding 11 can preferably be carried out electrically and / or electromechanically, pneumatic drives are also well conceivable. Alternatively, the folding mechanism can be purely mechanical, for example via spring-loaded, prestressed joints 9, which are triggered or adjusted in particular by means of a positive mechanism. Similarly, it is conceivable for the cover 6 to resort mainly to an elastic material which provides a required restoring force. Furthermore, a sufficient dimensional stability in the case of strong wind is required. For this reason, the folded state should be as compact as possible and have a low air resistance coefficient (CW value), which can be taken into account in particular by rounded edges.

6 shows the plan view of a windshield wiper 1 according to the invention with two folds 11 in the cover 6. In this way, a particularly compact folded state can be achieved in the operating state. In addition, two folds 11 or kinks allow for increased adaptability for closing the well 8 at rest, particularly when using rigid materials such as metal in conjunction with hinges 12 in the folds 11. 7 shows a top view of a windshield wiper 1 according to the invention with two hoses attached to the underside of the cover 6 for supplying wiping liquid to the nozzles, which are preferably also protected on the rear side of the cover 6. In the embodiment shown, a hose 10 is provided as a fluid channel on both sides of the wiper blade 5, which is supported at 3 locations, preferably via a clamping or latching connection. Optional jets may be located on the brackets. Alternatively, they may be distributed along the tube 10.

The components for cleaning the glass are well protected against damage by the rear mounting even during operation and allow a uniform and economical distribution of the wiper water. In addition, the rubber-like blade of the wiper blade 5 is spared, since this is then always wetted by water when operating the windscreen wiper system.

8 shows sections of a windshield wiper 1 according to the invention with two creases or folds 11 in the cover 6. The preferably linear creases are intended to bend in operation in the direction which is advantageous in particular for space and aerodynamic reasons. On the left in FIG. 8, the unfolded state is shown, while on the right conceivable position states during operation on the mostly oblique windshield 3 are illustrated.

Fig. 9 outlines the possible embodiments in the case of one or two creases for folding the cover 6, which are realized via pivotally mounted elements such as hinges 12. It is conceivable here, for example, a folding up of both lateral elements of the cover 6 in the operating state.

For example, in the embodiment at the bottom right in FIG. 9, FIG. 9 shows that the orientation of the holes from which the wiping liquid exits can influence within the lateral elements of the cover 6 in which direction the wiping liquid exits (downward 9 at the left-hand channel in the embodiment at the bottom right in FIG. 9, at the bottom right-hand diagonally at the right-hand channel in the embodiment at the bottom right in FIG. 9). If it is provided that the position of the lateral elements of the cover is variable, then this can also be used to change the orientation of the washing liquid jet.

It can also be seen from the orientation of the hole in the left channel in the embodiment at the bottom right in FIG. 9 that the hole can be protected from dirt if the lateral element of the cover 6 in which it is located is from the bottom right in Fig. 9 pivoted position in a position in which the left side member is horizontal.

FIG. 10 illustrates a possible nozzle 13 with a nozzle outlet 14 for connection to a hose 10, as may typically be used under the cover 6. This consists essentially of an end cap or connecting element 15 for fluid channels, which in particular adhesive, hot-tacky and / or clamping can be realized. Depending on the arrangement, the fluid, preferably given by the wiping water pressurized by an associated pump, can cover an angle range of almost 360 °, in particular by means of nozzle-like outlets, which are aligned in particular in the rearward direction.
