Description

Technical Field

[0001] This invention relates to the field of wiping, and more particularly to the field of wiping systems intended for use in motor vehicles. The invention relates to a wiping system comprising a shaft and a scraper, and to the shaft and scraper themselves relating to such a wiping system. Background Technology

[0002] Motor vehicles are typically equipped with wiping systems that include at least one wiper blade for wiping polished surfaces such as windshields. The wiper blade is driven by a drive motor via an arm between two end positions. The wiper blade is attached to the arm via a ball-and-socket joint, which requires a complex connector design. These wiping solutions are well-suited for large glass surfaces but less so for small surfaces due to their size, cost, and complexity. However, there are other wiping needs, particularly for small surfaces. For example, in autonomous vehicles, it is important to ensure the surface condition of several cameras and possibly lighting systems, as the safety of these vehicles largely depends on these devices.

[0057] To simplify the description, the same reference numerals will be used to denote the same or similar elements in various embodiments of the invention.

[0058] Figure 1 and Figure 11 A wiping system according to a first embodiment of the present invention is shown. The wiping system includes, on one hand, a drive shaft 1, and on the other hand, a wiper blade 20. The drive shaft, which will also be more simply referred to as shaft 1 or arm, is designed to be driven by a motor (not shown) to rotate about its longitudinal axis. The wiper blade includes a wiping element 21 designed to maintain contact with the surface to be wiped (not shown). The wiper blade 20 is driven to rotate by shaft 1, thereby allowing the wiping element 21 of the wiper blade to wipe the surface. For ease of maintenance of the wiping system, the wiper blade 20 is releasably mounted on shaft 1 in a user-friendly, simple, and reliable manner, as will be described in detail below.

[0059] Figure 2 A base 27 for a wiper blade 20 is shown, the base including a first end forming a connecting device 22 suitable for mating with a shaft 1. Two flat, straight, and parallel wiper blades 28, separated by a slot 29, extend from this connecting device to a second end of the wiper blade 20 opposite to the connecting device 22. The connecting device 22 has a generally circular external shape in the form of a disc and includes a central opening that more specifically enables the connection function. This opening has a generally circular shape that is enlarged relative to the circular opening by rectangular portions forming two enlarged portions 23, i.e., increasing the size of the opening. Between these two enlarged portions 23, the opening includes a generally circular portion interrupted by two segments or protrusions 24, thereby narrowing the opening and extending towards the center of the connecting device 22. The base 27 forms a rigid frame for the wiper blade 20, preferably made of metal.

[0060] Figure 3A wiper blade 20 is shown, in which a wiping element 21 is mounted on a frame 27. For this purpose, the wiping element 21 includes a lateral groove that allows engagement with a wiper blade 28 on the base 27. The wiping element 21 can thus slide along the wiper blade 28 of the frame. The wiping element 21 also includes an extension opposite to the base 27, which is formed in a known manner for contacting the wiper blade with the surface to be wiped. It should be noted that an end piece (not shown) may optionally be added to lock the wiping element 21 after it has been mounted on the base 27.

[0061] Figures 4 to 6 More specifically, the shaft 1 of the wiping system is shown. This shaft includes a first end portion forming a connecting device 2 intended to mate with a wiper blade 20. The first end portion includes a first section having a groove 4 extending on its outer periphery parallel to the axis of the shaft 1. The end portion also includes a cylindrical through-hole 3 perpendicular to the axis of the shaft 1, the cylindrical through-hole being intended to receive a pin 13 (e.g., in…). Figure 9 (See in the middle).

[0062] Shaft 1 then includes a second portion 5 with a circular cross-section and a decreasing diameter, which substantially corresponds to the diameter measured from one groove 4 of the first portion to the other. The shaft then includes a third portion 6 with a diameter larger than that of the second portion, substantially corresponding to the diameter of the first portion outside the groove 4. Finally, the shaft includes a fourth portion 7 with an even larger diameter, which extends to a second end 9 intended for connection to a drive motor (not shown).

[0063] The wiping system further includes a flexible device ( Figure 7 As shown in the diagram, it is for mounting on shaft 1 to mate with the wiper blade, as will be explained later. According to this embodiment, the resilient device includes, for example, arranged in... Two flat washers 14 on both sides of the elastic washer 15.

[0064] Figure 8 and Figure 9 A shaft 1 with an elastic device mounted thereon is shown. It can be seen that a first flat washer 14 rests on the end of the fourth part 7, which has a larger diameter than the shaft, and two other washers 14 and 15 rest on the first flat washer 14. Figure 9 The pin 13, which is inserted into the cylindrical opening 3 mentioned above, is further shown.

[0065] Figure 1 A fully assembled wiping system is shown. Figure 10 and Figure 11 The wiping system is shown assembled, but some components have been removed to better reveal certain details, particularly the relative positioning of the individual components at their connection points. Specifically, Figure 11 The base 27 is positioned on axis 1 in a view taken from below.

[0066] The operation of the wiping system will now be described in detail, especially the installation and removal of the wiping blade 20 on shaft 1.

[0067] The assembly of the wiping system involves first installing a flexible device on shaft 1, and then installing pins 13 to secure everything. At this stage, the wiping system is in... Figure 9 The state shown is as follows. Now, the base 27 of the wiper blade is mounted on the shaft 1. The connecting device 22 of the base is brought close to the corresponding connecting device 2 of the shaft 1. For this purpose, the base 27 is oriented such that the widened portion 23 of the base is positioned opposite to the pin 13. The dimensions of these widened portions are designed to allow the pin 13 to pass through the opening formed in the connecting device 22 of the base, which represents the female connector of the coupling. Furthermore, in this orientation, the protrusion 24 is arranged opposite the groove 4: these shapes are designed to allow the protrusion 24 to pass into the groove 4. Thus, in this orientation of the element, the base 27 can be translated along the shaft 1. This translational movement continues until the base 27 contacts the flat washer 14 of the elastic device. The movement then continues by compressing the elastic device, more precisely the elastic washer 15, until the connecting device 22 of the base 27 reaches the second part 5 of the shaft 1: in this position, the base 27 then rotates a quarter turn and is released. Under the action of the elastic device, the base moves automatically upward until it abuts against the pin 13. In the final position or operational configuration, especially Figure 10 and Figure 11 As can be seen, the base 27 is therefore at the level of the first part of the shaft 1, and no longer at the level of the smaller diameter second part 5. As a result of this quarter turn, the enlarged portion 23 of the opening of the connecting device 22 is no longer aligned with the pin 13, but is arranged at a right angle. The smaller diameter area of ​​the opening of the connecting device 22 is then positioned in a straight line with the pin 13, thus no longer allowing the base 27 to be removed. On the other hand, the connecting device 2 of the shaft 1 includes four grooves 4 evenly distributed around the circumference of the shaft 1. Therefore, when the base 27 rotates a quarter turn, the protrusions 24 of the connecting device 22 of the base 27 move from one groove 4 to an adjacent groove. Therefore, when the base moves upward, these protrusions 24 return to their positions within the grooves 4. This geometry achieves an anti-rotation function for the base 27 relative to the shaft 1 and ensures that the base 27 can be reliably driven by the shaft 1. Finally, under the elastic pressure of the elastic device, the base 27 always remains against the pin 13, thus forming a locking device. This arrangement ensures the correct positioning of the wiper blade, so that the wiping element 21 of the wiper blade maintains effective contact with the surface to be wiped.

[0068] The removal of the wiper blade is performed by reversing the operation. First, the wiper blade is pressed against the elastic device to reach the second part 5 of the shaft 1, which allows the wiper blade to rotate a quarter turn, thereby allowing the widened part 23 to be repositioned to align with the pin 13, thus allowing the wiper blade to be translated and removed from the shaft 1.

[0069] Naturally, the present invention is not limited to the embodiments shown. In particular, the complementary shapes of the connecting device 2 of shaft 1 and the connecting device 22 of wiper blade 20 can differ from the complementary shapes shown, as these complementary shapes allow for a first assembly / disassembly position and a second operating position. On the other hand, the transition from the first position to the second position can be achieved by rotation other than a quarter turn. Finally, the geometry of the components can differ, as long as it enables the wiper blade to prevent rotation relative to the shaft in the second operating position. Therefore, any groove, notch, etc., can be used.

[0070] Figures 12 to 14 A variation of the first embodiment is shown in which the wiping blade 20 is different, while the shaft 1 remains the same. (As can be seen in...) Figure 12 and Figure 13 As seen in the previous description, the base 27 of the wiper blade 20 has the same connection device 22 as the connection device in the previously described embodiment, but includes a different wiper blade 28 for receiving the wiper element 21. Each wiper blade 28 has a grooved profile, open on the side facing the surface to be wiped. This shape allows the wiper blade 28 to have two lower retaining claws. This profile allows for insertion and translational movement of the wiper element 21, the base of which has a corresponding capital I-shaped cross-section (with two vertical bars at both ends of the I). It should be noted that the width of this wiper blade is smaller than the width of the wiper blade described above, which reduces interference with the operation of the element to be wiped (e.g., a camera in a motor vehicle).

[0071] Figures 15 to 22 A second embodiment of the invention is shown, the main difference from the first embodiment being that the second embodiment includes an anti-rotation collar 16 located between the wiper blade 20 and the pin 13, thereby achieving an anti-rotation function. This solution simplifies the geometry of the shaft 1, as will be described below.

[0072] In this second embodiment, the wiper blade 20 primarily comprises a base 27 and a wiping element 21 identical to those in the variant of the first embodiment. An anti-rotation collar 16 (more specifically in...) Figure 16 (As can be seen in the image) is intended for use on the wiper blade 20, such as Figure 18 and Figure 19As shown in the diagram. The anti-rotation collar includes two aligned recesses 17 with a V-shaped cross-section, the shapes of which are configured to mate with the two ends of the pin 13, as shown in... Figure 15 , Figure 21 and Figure 22 As seen in the image. The anti-rotation collar further includes two extensions 19 that form connecting elements for mounting the anti-rotation collar onto the wiper blade 20.

[0073] like Figures 17 to 19 As shown, the anti-rotation collar 16 is secured to the connection device 22 of the base 27 of the wiper blade. For this purpose, the connection device 22 includes two lateral openings 25 arranged opposite to the extension 19 of the anti-rotation collar 16, thereby allowing the anti-rotation collar to be secured by clamping, threaded connection, or any other mechanical solution or by gluing. The anti-rotation collar 16 includes a central opening with the same shape as the opening of the connection device 22 on the base, or a central opening with a larger surface area, which overlaps the opening of the connection device 22.

[0074] Due to the use of this additional element (i.e., the anti-rotation collar 16), compared to the shape of the shaft 1 in the first embodiment, the shaft 1 of the wiping system (especially in...) Figure 20 As can be seen in the image, it has a simplified shape. In particular, the first three sections of the shaft 1 are replaced by a single cylindrical section 6, which includes a cylindrical opening 3 for receiving the pin 13. The same resilient device, in particular the three washers 14, 15, 14 mentioned above, can be positioned around the shaft 1 as in the first embodiment.

[0075] The connecting device 22 for the wiper blade 20 is also simplified. This connecting device no longer includes the protrusion 24 because the shaft 1 no longer includes the groove 4. The connecting device includes a generally circular central portion and two enlarged portions 23, the diameter of which is slightly larger than the diameter of the cylindrical portion 6 of the shaft 1. The shapes of these two enlarged portions correspond to the shape of the pin 13. The wiper blade is thus mounted on the shaft and then rotated a quarter turn to position the housing 17 of the anti-rotation collar 16 below the end of the pin 13. When the wiper blade 20 is released, these recesses 17 engage with the pin 13, and this arrangement is firmly held in place by the elastic device 15. In this way, the wiper blade cannot disengage from the shaft 1 or rotate about the shaft 1. Figure 21 and Figure 22 The relative positioning of the anti-rotation collar 16 and the shaft 1, and especially the pin 13, is shown more precisely. It is therefore obvious that the anti-rotation collar not only participates in the aforementioned anti-rotation function, but also participates in the locking function of the wiper blade 20 in the operating configuration.

[0076] In a variant of the second embodiment (not shown), the anti-rotation collar 16 may not be a separate element, but may be integrally formed with all or part of the wiper blade, such as... Figure 28 The situation is illustrated in the embodiments shown.

[0077] Figures 23 to 35 A third embodiment of the present invention is shown.

[0078] like Figures 24 to 26 As shown, this third embodiment differs from the previous two embodiments in that shaft 1 is in the form of two separate main components attached to each other. Figure 24 As shown, the lower shaft portion 7 features a simplified perforated design. Figure 25 The upper shaft portion 6 shown includes a connector for mating with the lower shaft portion 7, for attachment by, for example, welding to form a shape. Figure 26 The resulting shaft 1 shown has a similar overall shape to the shaft of the second embodiment. In this embodiment, the pin 13 is no longer a separate element, but can be integrally formed with the upper shaft portion. In fact, therefore, before fixing the upper shaft portion 6, the elastic device, in particular the three washers 14, 15, 14 mentioned above, can be installed on the lower shaft portion 7, thereby combining the elastic device and completing the shaft 1.

[0079] Figures 27 to 35 A variation of the third embodiment is shown, in which the wiper blade is combined with a device for dispensing cleaning fluid. For this purpose, the wiping system includes a hose 30 for supplying cleaning fluid to the wiper blade 20.

[0080] Figures 28 to 31 Therefore, a base 27 for the wiper blade 20 is shown. This base includes a first end piece 32, which includes a connecting device 22 for the shaft 1, then a cleaning fluid inlet portion, and then an outlet 35. The cleaning fluid inlet portion includes an inlet connector 33, and the outlet allows the cleaning fluid to be directed toward the wiping element 21 and then toward the surface to be wiped. Two parallel wiper blades 28 can be fixed in the first end piece 32. A second end piece 34 is located at the opposite ends of the two wiper blades 28 to form a... Figure 29 and Figure 31 The base 27 is visible in the middle. The wiping element 21 is then fixed to the base 27 to form a... Figure 32 The wiper blade 20 shown. The flexible hose 30 is bent to match the shape of shaft 1. Figure 33 The device shown has one end attached to the inlet connector 33 and a second end 31 for connecting to a cleaning fluid supply device (not shown).

[0081] The shaft 1 includes a lug 8 at its second end 9 for clamping the tube 30 at the second end 31 of the tube, the second end being in a straight line shape parallel to the shaft 1, so as to minimize the total space occupied by the tube 30.

[0082] Finally, the present invention is not limited to the described embodiments. In particular, these embodiments can be combined with each other.

[0083] In all embodiments, the base 27 can be made of metal or even rigid plastic. As is known, the wiping element 21 is preferably made of rubber. The collar can be made of plastic or metal. The shaft 1 is preferably made of metal.

[0084] Furthermore, the various components of the wiping system can take other forms without departing from the concept of the invention. For example, any other resilient device can be used, such as including at least one spring, particularly a coil spring or leaf spring. Alternatively, the resilient device can be mounted on the wiper blade 20, at the wiper blade connection device 22, rather than on the shaft. The drive shaft 1 and the wiper blade 20 can take different forms. For example, the pin on the shaft 1 can take any other form to provide a stop for the wiper blade 20 in the operating configuration. In an embodiment, the pin forms two symmetrically opposite stops about the axis of the shaft to ensure stability in the operating configuration. Alternatively, the shaft can include more than two stops distributed around its axis, for example, three or four stops. Advantageously, the shaft is symmetrical about its axis, which also represents the axis of rotation of the shaft. The anti-rotation device can also take any form other than those shown: the anti-rotation device includes complementary anti-rotation devices arranged on the drive shaft 1 and the wiper blade 20. The anti-rotation device can be independent of or in combination with the wiper blade locking device. The first embodiment uses grooves evenly distributed around the shaft. Alternatively, any notch machined on the shaft can be used.

[0085] The connection between the drive shaft 1 and the wiper blade 20 can also be different, as long as the connection allows for releasable assembly of the drive shaft and wiper blade involving simple relative rotation, includes anti-rotation devices and locking devices, and involves a resilient mechanism. In the described embodiment, the wiper blade therefore includes a female connection device, and the shaft 1 includes a complementary male connection device. These female / male parts can be reversed. In any case, the wiper blade 20, or more simply, a separate part such as the base 27, or even a separate part 32 of the base 27, includes a connection device 22 suitable for releasable connection to the drive shaft 1 of the wiper blade 20, which includes a first orientation that allows installation / removal relative to the drive shaft 1 and a second orientation that does not allow such installation / removal.

[0086] This invention is particularly suitable for wiping small, effective surfaces of cameras or lighting equipment, especially those of motor vehicles. However, the invention remains compatible with any other application requiring surface cleaning.
