Description

Telescopic cleaning device for motor vehicle and associated motor vehicle

[0001] The present invention falls within the field of devices for cleaning motor vehicle equipment.

[0002] Motor vehicles increasingly include detection or vision equipment with a protective optical surface, the cleanliness of which affects the performance of this equipment, so it is necessary to provide a cleaning device to keep its optical surfaces clean.

[0003] Furthermore, the size of these optical surfaces is increasingly large, so that it becomes difficult to cover all of these surfaces with the devices known from the state of the art such as fixed spray nozzles. It is also appropriate to limit the number of these nozzles so as to limit the consumption of cleaning liquid.

[0004] Furthermore, it is also important not to distort the visual appearance and aerodynamics of the vehicles on which the devices are fitted.

[0005] Finally, it is appropriate to limit the energy consumption of these cleaning devices, particularly with a view to their installation on electric vehicles since this could impact the vehicle's autonomy.

[0006] The aim of the present invention is therefore to find a solution making it possible to at least partially resolve the technical problems mentioned above.

[0007] To this end, the present invention relates to a telescopic cleaning device intended to project a cleaning and / or drying fluid towards an optical surface of a motor vehicle, said telescopic cleaning device comprising a hydraulic actuator configured to move a fluid distribution element, said hydraulic actuator comprising a piston of generally cylindrical shape configured to move axially from a retracted position to a deployed position under the action of the cleaning or drying fluid, said piston being mechanically and fluidically connected to the fluid distribution element and comprising a guide relief, in which the guide relief comprises at least one curved section extending over the cylindrical surface of the piston so as to drive the piston in rotation about the axis of the cylinder during the axial movement of the piston.

[0008] The use of a guide relief with a curved section allows the distribution element comprising projection nozzles to rotate and thus allow spraying over a large area. In addition, the telescopic device allows for a compact and concealed device in the retracted position.

[0009] According to another aspect of the present invention, the curved section has a helical shape.

[0010] According to another aspect of the present invention, the guide relief comprises at least one straight section extending over the cylindrical surface of the piston so as to drive the piston in translation along the axis A of the cylinder during an axial movement of the piston.

[0011] Thanks to these features, the piston can undergo additional translation so that the fluid distribution element is at an optimal distance from the surface to be cleaned when spraying fluid.

[0012] According to another aspect of the present invention, during a movement of the piston between the retracted position and the deployed position, the piston performs a translation only along the axis A then a translation along the axis A and a rotation around the axis A.

[0013] Thanks to these features, the piston can be extracted from the housing before spraying fluid onto the surface to be cleaned.

[0014] According to another aspect of the present invention, the hydraulic actuator comprises a casing, said casing comprising an orifice provided at one end of the casing and said orifice being configured to allow the passage of the piston, said orifice comprising a shape substantially complementary to the section of the guide relief of the piston to allow precise guiding of the piston.

[0015] For example, when moving the piston from the retracted position to the extended position, the piston movement is guided by the cooperation of the complementary shape of the orifice and the straight section or the curved section.

[0016] For example, when moving the piston from the retracted position to the extended position, the piston movement is guided first by the cooperation of the complementary shape of the orifice and the straight section and then by the cooperation of the complementary shape of the orifice and the curved section.

[0017] For example, when moving the piston from the retracted position to the extended position, the piston movement is guided first by the cooperation of the complementary shape of the orifice and the curved section and then by the cooperation of the complementary shape of the orifice and the straight section.

[0018] For example, in the retracted position, the straight section is closer to the complementary shape of the orifice than the curved section.

[0019] For example, in the retracted position, the curved section is closer to the complementary shape of the orifice than the straight section.

[0020] For example, in the deployed position, the curved section is closer to the complementary shape of the orifice than the straight section.

[0021] For example, in the deployed position, the straight section is closer to the complementary shape of the orifice than the curved section.

[0022] For example, the straight section and the curved section are joined.

[0023] For example, the guide relief includes an alternation of straight and curved sections.

[0024] For example, the curved section SC has an irregular curvature.

[0025] According to another aspect of the present invention, the piston is formed by a hollow body arranged around a central cylinder, said hollow body comprising a central axial portion whose internal section is complementary to the central cylinder and a first extreme axial portion whose internal section is greater than the internal section of the central axial portion.

[0026] According to another aspect of the present invention, at least one peripheral fluid circulation channel is provided in the first extreme axial portion.

[0027] According to another aspect of the present invention, the piston also comprises a second extreme axial portion in which a central channel for circulating the fluid is provided.

[0028] According to another aspect of the present invention, the hydraulic actuator also comprises a seal disposed radially between the central cylinder and the piston.

[0029] According to another aspect of the present invention, the hydraulic actuator is configured so that between the retracted position and an intermediate position, the seal faces the central axial portion of the piston and is configured to block the passage of the cleaning and / or drying fluid from the at least one peripheral fluid circulation channel to the central fluid circulation channel of the second extreme axial portion and, between the intermediate position and the deployed position, the seal faces the first extreme axial portion allowing the passage of the cleaning and / or drying fluid from the at least one peripheral fluid circulation channel to the central fluid circulation channel of the second extreme axial portion.

[0030] According to another aspect of the present invention, the fluid distribution element comprises an internal fluid distribution conduit and is configured to be fixed on the second axial end portion of the piston and to put the internal fluid distribution conduit in fluid communication with the central fluid circulation channel of the piston.

[0031] According to another aspect of the present invention, the fluid distribution element extends at least partially in a direction substantially perpendicular to the axial direction.

[0032] According to another aspect of the present invention, the fluid dispensing element comprises a plurality of nozzles distributed along the length of the dispensing element.

[0033] According to another aspect of the present invention, at least one of the nozzles has a different orientation from the other nozzles so as to project the cleaning and / or drying fluid over a larger area.

[0034] According to another aspect of the present invention, the hydraulic actuator also comprises an elastic return means configured to constrain the piston in its retracted position.

[0035] According to another aspect of the present invention, the elastic return means is a helical spring disposed around the piston.

[0036] According to another aspect of the present invention, a first end of the helical spring bears against the housing of the hydraulic actuator and a second end, opposite the first end, bears on a collar of the piston.

[0037] According to another aspect of the present invention, the cleaning device also comprises a reservoir of the cleaning fluid in fluid communication with the hydraulic actuator and a pumping device configured to allow the supply of cleaning and / or drying fluid to the hydraulic actuator.

[0038] The present invention also relates to a motor vehicle comprising a cleaning device as described above.

[0051] The following embodiments are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the features apply only to a single embodiment. Single features of different embodiments may also be combined or interchanged to provide other embodiments.

[0052] The present invention relates to a telescopic cleaning device for a motor vehicle, in particular for optical surfaces associated with sensors of the motor vehicle such as lidar sensors, cameras or laser sensors. Such a telescopic cleaning device can also be used for cleaning a windshield or a headlight lens.

[0053] Figures 1 and 2 show a telescopic cleaning device 1 according to an embodiment of the present invention. In the, the fluid projections 10 are represented by triangles.

[0054] The telescopic cleaning device 1 comprises a hydraulic actuator 3 and a fluid distribution element 5 configured to be moved by the hydraulic actuator 3.

[0055] The distribution element 5 can extend perpendicular to the axis A of the hydraulic actuator 3 as shown in the. However, an angle other than 90° can also be chosen.

[0056] The distribution element 5 has for example a length between 5cm and 50cm, for example between 15cm and 25cm for example 20cm.

[0057] The distribution element 5 corresponds for example to a spray bar comprising a plurality of nozzles 7 (visible in the). In the example of Figures 1 and 2, the distribution element 5 comprises five nozzles but a different number of nozzles 7 is possible, for example a single nozzle 7. In addition, at least one of the nozzles 7 may have a different orientation from the other nozzles 7. For example in the present case, the nozzle 7 located at the end of the distribution element 5 is arranged on a surface having a different orientation from the other nozzles 7. The other nozzles 7, although positioned on a common surface, may have different orientations to cover a larger spraying surface.

[0058] The distribution element 5 comprises for example an internal conduit 9 (visible in the sectional view of the) configured to supply the different nozzles 7 with fluid.

[0059] The hydraulic actuator 3 comprises a piston 11 configured to be moved between a retracted position and an extended position under the action of a cleaning and / or drying fluid.

[0060] The hydraulic actuator 3 also comprises a casing 13 in which the piston 11 is partially arranged. The casing 13 has, for example, a generally cylindrical shape and comprises, for example, a nozzle 15 arranged at its first end. The nozzle 15 is configured to receive one end of a supply conduit 16 (visible in the) for the cleaning and / or drying fluid. The other end of the supply conduit 16 is, for example, connected to a reservoir 18 for the cleaning and / or drying fluid. A pumping device 20 such as a pump is arranged between the reservoir 18 and the hydraulic actuator 3 to allow the cleaning and / or drying fluid to be supplied into the supply conduit 16. Several supply conduits may be connected to the same reservoir 18 and the same pump 20. In addition, one or more valves, in particular solenoid valves, may be used to manage the supply of the different conduits.In the example of the, a three-way valve 22 is arranged between the reservoir 18 and the pump 20 to select the supply fluid for the hydraulic actuator 3. Depending on the position of the three-way valve 22, the pump 20 sucks in the cleaning liquid 10 arranged in the reservoir 18 or sucks in air to be used for drying the optical surface associated with the telescopic cleaning device 1.

[0061] Alternatively, the casing 13 may comprise two end pieces 15 arranged at its first end and configured to be connected to two separate conduits to allow a supply of two separate fluids, for example a cleaning fluid and a drying fluid such as air or a cleaning fluid and a rinsing fluid.

[0062] The casing 13 also comprises at its second end, opposite the first end, an orifice 14 (visible on the) configured to allow the passage of the piston 11. The piston 11 is configured to protrude from the second end of the casing 13.

[0063] The piston 11 has a generally cylindrical shape. The piston 11 also comprises a guide relief 17, for example a bulge or rib (visible on the) which extends on its cylindrical external face. Alternatively, the guide relief 17 can be produced by a groove (hollow relief) formed on the cylindrical surface of the piston 11.

[0064] The orifice 14 of the casing 13 comprises a shape complementary to the guide relief 17 of the piston 11, for example a notch 12 complementary to the rib 17 as shown in the figure or a protuberance complementary to the groove in the case of a groove.

[0065] The piston 11 may comprise several guide reliefs 17 arranged symmetrically with respect to the axis A, for example two diametrically opposed ribs 17 as shown in the.

[0066] In addition, the guide relief 17 comprises at least one curved section SC extending over the cylindrical surface, i.e. a section not parallel to the axis A of the cylinder of the piston 11 so that the piston 11 rotates around the axis A when it is moved to its deployed position, which also causes the rotation of the distribution element 5 and thus makes it possible to increase the spraying surface. The rotation of the piston 11 is for example between 30° and 100°, in particular between 60 and 80°, for example 70°.

[0067] In the example of 1a, the guide relief 17 comprises a straight section SD associated with a translation of the piston 11 without rotation around the axis A and a curved section SC of helical shape associated with a translation of the piston 11 coupled with a rotation of the piston 11 around the axis A. Thus, during its movement between the retracted position and the deployed position, the piston 11 is first translated (without rotation) during the projection of the straight section SD through the second end of the casing 13 then the piston 11 is translated with rotation around the axis A during the projection of the curved section SC through the second end of the casing 13. The distribution element 5 is coupled in rotation to the piston 11 and therefore also translated then subjected to a translation-rotation like the piston 11.

[0068] Alternatively, the guide relief 17 may comprise a single curved section SC, an alternation of straight sections SD and curved sections SC or a curved section SC whose curvature is irregular or a combination of these alternatives.

[0069] The piston 11 is formed by a hollow body, more specifically a hollow cylinder comprising a central channel 19 (visible in the sectional view of the) configured to receive a central cylinder 21 of the hydraulic actuator 3. The central cylinder 21 is configured to be fixed relative to the casing 13. The central channel 19 can extend over the entire length of the piston 11.

[0070] The piston 11 comprises a first axial end portion 11a whose internal section is greater than the external section of the central cylinder 21. This first axial end portion 11a comprises for example at least one peripheral channel 23 for circulation of the fluid (the peripheral channel(s) 23 may be in fluid communication with the central channel 19 of the first axial end portion 11a, the latter receiving the central cylinder 21 in the retracted position). In the example of 1a, the first axial end portion 11a comprises a plurality of peripheral channels 23 distributed around the central channel 19. Indeed, the section of the first axial end portion 11a is configured to allow the passage of the cleaning and / or drying fluid inside and along the piston 11 around the central cylinder 21.

[0071] The piston 11 also comprises a central axial portion 11b whose internal section is complementary to the external section of the central cylinder 21 and a second extreme axial portion 11c which comprises a central channel 19 configured to be in fluid communication with the internal conduit 9 of the distribution element 5. The section of the central channel 19 at the level of the second extreme axial portion 11c may be smaller than the external section of the central cylinder 21 because this second extreme axial portion 11c is not intended to receive the central cylinder 21 but is only intended to transmit the fluid coming from the first extreme axial portion 11a and from the central axial portion 11b towards the distribution element 5.

[0072] The hydraulic actuator 3 may also comprise a seal 25 such as an O-ring arranged radially between the central cylinder 21 and the piston 11. A groove is for example provided at the end of the central cylinder 21 and configured to receive the seal 25 as shown in the figure.

[0073] The seal 25 makes it possible to prevent the passage of fluid from the first end axial portion 11a to the second end axial portion 11c when the central axial portion 11b of the piston 11 is positioned around the seal 25. Thus, when the central axial portion 11b of the piston 11 is positioned around the seal 25, the fluid received at the first end of the casing 13 tends to move the piston 11 axially without the cleaning or drying fluid being transmitted to the distribution element 5. When the first end axial portion 11a reaches the seal 25 due to the axial movement of the piston 11, the fluid located in the first end axial portion 11a is transmitted to the second end axial portion 11c via the central axial portion 11b and then to the nozzles 7 of the distribution element 5 via the internal conduit 9.

[0074] The lengths of the first extreme axial portion 11a, of the central axial portion 11b and of the central cylinder 21 can be determined so as to obtain the projection of the fluid in the desired positions of the distribution element 5. For example, in the present example, the spraying can begin when the piston 11 begins its rotation around the axis A because the curved section SC of the guide relief 17 reaches the orifice 14 of the casing 13.

[0075] A different configuration of the piston 11 is also possible, for example an alternation of internal sections complementary to the external section of the central cylinder 21 and internal sections greater than that of the external section of the central cylinder 21 to obtain several projection ranges.

[0076] As shown in Figures 5 and 6, the hydraulic actuator 3 also comprises an elastic return means 27 such as a helical spring configured to constrain the piston 11 into the retracted position, in particular in the absence of fluid supply to the hydraulic actuator 3. The helical spring 27 is for example positioned radially between the piston 11 and the casing 13. More precisely, a first end of the helical spring 27 may bear against the casing 13 of the hydraulic actuator 3 and a second end, opposite the first end, of the helical spring 27 may bear on a collar 29 of the piston 11.

[0077] The elastic return means 27 thus makes it possible to return the piston 11 to the retracted position after the projection of the cleaning and / or drying liquid without requiring an electric motor.

[0078] Thus, in operation, when a command to clean the optical surface is received, the pump 20 is activated (or a supply valve is opened) to transmit cleaning liquid 10 from the reservoir 18 to the hydraulic actuator 3 via the supply conduit 16. In the absence of transmission of cleaning liquid 10, that is to say before the activation of the pump 20 (or before the opening of the supply valve), the piston 11 is in its retracted position (mostly inside the casing 13) due to the action of the helical spring 27. In this retracted position, the central cylinder 21 and the seal 25 are opposite the central axial portion 11b of the piston 11. The central cylinder 21 and the seal 25 are thus configured to block the passage of the cleaning and / or drying fluid from the peripheral fluid circulation channels 23 to the central fluid circulation channel 19. of the second extreme axial portion 11c.

[0079] After actuation of the pump 20, the cleaning liquid 10 is transmitted to the hydraulic actuator 3 via the end piece 15 of the casing 13. The cleaning liquid 10 is then transmitted to the peripheral channels 23 of the first end axial portion 11a. However, the cleaning liquid 10 cannot be transmitted to the central channel 19 of the second end axial portion 11c due to the presence of the central cylinder 21 so that the inflow of cleaning liquid 10 causes the piston 11 to move in translation towards its deployed position. The piston 11 is moved to an intermediate position in which the first end axial portion 11a exceeds the position of the seal 25 (or even the end of the central cylinder 21).Furthermore, in the present example, this intermediate position also corresponds to the position in which the start of the curved section SC of the guide relief 17 reaches the orifice 14 of the casing 13, which causes the piston 11 to rotate around the axis A. Thus, from the intermediate position, the distribution element 5 begins its rotation around the axis A.

[0080] After passing the intermediate position, the cleaning liquid 10 passes from the peripheral channels 23 to the central channel 19 of the central axial portion 11b and the second extreme axial portion 11c. When the cleaning liquid 10 reaches the end of the second extreme axial portion 11c, it is transmitted to the conduit 9 of the distribution element 5 which allows the supply of the different projection nozzles 7.

[0081] From the intermediate position, the translation-rotation of the piston 11 and the guide element 5 fixed on the piston 11 is accompanied by the spraying of the cleaning liquid 10 by the projection nozzles 7 thus making it possible to effectively spray the cleaning liquid 10 onto a large optical surface. When the piston 11 reaches its deployed position, its translation-rotation is stopped. The pump 20 can be configured so as to be deactivated when the piston 11 reaches this deployed position (or the supply valve configured to close). The pump 20 (or the supply valve) is for example configured to pump a volume of cleaning liquid 10 making it possible to reach the deployed position of the piston 11. It is also possible to provide a position sensor for the piston 11 connected with the pump 20 (or the supply valve) to stop the pumping when the piston 11 reaches the deployed position.

[0082] Once the pumping has stopped, the piston 11 (and therefore the distribution element 5) is returned to its retracted position under the action of the helical spring 27. The retracted position of the distribution element 5 may correspond to a position in which the distribution element 5 is flush with the bodywork elements of the motor vehicle surrounding said distribution element 5, which makes it possible not to degrade the aerodynamics of the vehicle. In addition, the passage of the piston 11 from its retracted position to its intermediate position makes it possible to move the distribution element 5 so that it projects from the bodywork elements and the optical surface to be cleaned, thus making it possible to spray the cleaning liquid 10 effectively onto the optical surface when the piston 11 passes beyond the intermediate position.

[0083] Similarly, pumping air (e.g., by changing the position of the three-way valve 22) can allow air to be sprayed onto the optical surface to allow the optical surface to be dried, for example, after spraying the cleaning liquid 10. As with the cleaning liquid 10, the piston 11 will be moved from its retracted position to its intermediate position by the pressure of the air supplied via the supply duct 16 and then the air will pass into the central channel 19 and towards the distribution element 5 to be sprayed by the projection nozzles 7 towards the optical surface.

[0084] The present invention also relates to a motor vehicle comprising a telescopic cleaning device 1 as described previously.

[0085] Thus, the use of a telescopic cleaning device 1 as described above makes it possible to obtain effective spraying over a large surface area due to the rotation of the piston 11 and the distribution element 5 during spraying while limiting the consumption of cleaning liquid due to the fact that the projection nozzles 7 are close to the optical surface to be cleaned, which limits projections outside the optical surface. In addition, in the retracted position, the distribution element 5 can be flush with the bodywork (or even retracted into an internal housing of the bodywork) so that the aerodynamics and visual appearance of the vehicle are preserved. Finally, such a cleaning device 1 has limited energy consumption since its operation can be carried out via the activation of a single pump 20 and without any other device requiring an electrical power supply.
