Description

Technical Field

[0001] This invention relates to the field of cleaning fluid spraying systems for motor vehicles, and particularly to cleaning systems comprising nozzles on wiper arms and / or on the wiper blades themselves. Background Technology

[0002] Spraying cleaning fluid onto the wiper arms and / or blades involves delivering the cleaning fluid to the nozzles. This delivery is achieved through conduit, also known as a hose, within which the cleaning fluid flows. For example, the propulsion of the cleaning fluid in the conduit can be achieved by a pump in the cleaning system, configured to pump the cleaning fluid from a reservoir to the nozzles.

[0003] Therefore, the pipe should be attached to the wiper arm. For this purpose, clamps exist that can be evenly distributed along the pipe and wiper arm. However, existing clamps generally have certain disadvantages, such as inconvenient installation and / or requiring a long installation time, and they can obstruct the pipe when installed on the wiper arm.

[0004] Therefore, it is necessary to find a solution that facilitates attaching the pipe to the wiper arm. Summary of the Invention

[0005] To this end, a clip for attaching a fluid conduit to a wiper arm of an injection system of a motor vehicle is proposed. The clip has an overall V-shaped shape, the base of which forms a housing for a portion of the fluid conduit. It includes a first retaining arm and a second retaining arm located at a first end and a second end of the V-shaped shape and extending toward each other. The retaining arms are asymmetrical in an axial direction parallel to the fluid conduit, such that the space between the two retaining arms forms an opening with a diverging shape in the axial direction.

[0006] According to one aspect of the invention, the end of the retaining arm is straight and has an angle of inclination of 5° to 10° relative to the axial direction.

[0007] According to another aspect of the invention, at the maximum spacing of the retaining arms, the distance between the retaining arms is 90% to 110% of the width of the wiper arm.

[0008] According to another aspect of the invention, at the minimum spacing of the retaining arms, the distance between the retaining arms is 70% to 90% of the width of the wiper arm.

[0009] According to another aspect of the invention, the retaining arm has a beveled shape on its outer side to facilitate the insertion of the clip onto the wiper arm.

[0010] According to another aspect of the invention, the angle of the inclined plane shape is 15° to 20°.

[0011] According to another aspect of the invention, the overall V-shaped shape has rounded corners.

[0012] According to another aspect of the invention, the clamp includes two protrusions respectively disposed on two inner walls of a V-shape and defining a receptacle for receiving said portion of the fluid conduit.

[0013] According to another aspect of the invention, the protrusion extends from the inner wall of the V-shape at an angle of 90° to 120°, and the height of the protrusion is 0.1 to 0.3 times the diameter of the fluid conduit.

[0014] According to another aspect of the invention, the clip is made of a plastic material, particularly ethylene propylene.

[0015] The present invention also relates to a method for attaching a fluid conduit to a wiper arm of a jet system in a motor vehicle, the method comprising the steps of:

[0016] Provide at least one clip as described above.

[0017] A portion of the fluid conduit is placed in the housing of the at least one clamp, particularly by separating the ends of the V-shape or by sliding the fluid conduit into the bottom of the V-shape.

[0018] The at least one clip is placed on the wiper arm by placing the retaining arm against the wiper arm and by pushing the clip toward the wiper arm so that a portion of the wiper arm can be inserted into the V-shape. Attached Figure Description

[0022] Figure 3 A perspective diagram showing the clamp positioned on the wiper arm is shown; and

[0023] Figure 4 A flowchart is shown illustrating the steps of a method for attaching a fluid conduit to a wiper arm.

[0024] In these figures, the same elements have the same reference labels. Detailed Implementation

[0025] The following embodiments are examples. Although the specification relates to one or more embodiments, this does not necessarily mean that every reference relates to the same embodiment, or that each feature applies only to one embodiment. Features of different embodiments may also be combined or interchanged to provide other embodiments.

[0026] Embodiments and examples of the present invention relate to a clamp 1 specifically for a liquid injection system in motor vehicles. For example... Figure 3 As shown, the clip 1 is designed to be attached to a wiper arm 100 of a fluid conduit 102 for supplying cleaning fluid at a nozzle (not shown) disposed on the wiper arm 100 and / or on a wiper blade mounted on the wiper arm 100.

[0027] Figure 1 A perspective view of a clip 1 with an overall V-shaped shape is shown, including a first retaining arm 3a and a second retaining arm 3b, which are located at the first end 1a and the second end 1b of the V-shape, respectively, and extend toward each other. The space between the two retaining arms 3a and 3b forms an opening with a diverging shape in the axial direction, such that the retaining arms 3a and 3b are asymmetrical in this axial direction. The axial direction shown by the axis Δ in the figure corresponds to the direction parallel to the fluid conduit 102 or the wiper arm 100 when the clip 1 is mounted on a portion of the fluid conduit 102 and / or a portion of the wiper arm 100. Figures 1 to 3 In the example, the ends of the retaining arms 3a and 3b are straight and have an angle of 5° to 10° relative to the axial direction. However, other non-linear shapes can also be used, even if these shapes are divergent, such as curved and significantly convex shapes. The divergent shape formed by the space between the retaining arms 3a and 3b facilitates the mounting of the clip 1 on the wiper arm 100 and also allows for proper centering of the clip 1. The distance between the retaining arms 3a and 3b at their maximum spacing is, for example, 90% to 110% of the width of the wiper arm 100, so that the clip 1 can be easily inserted and positioned on the wiper arm 100. The distance between the retaining arms 3a and 3b at their minimum spacing is, for example, 70% to 90% of the width of the wiper arm 100, so that the clip 1 can be reliably attached to the wiper arm 100.

[0028] The retaining arms 3a and 3b may also have a beveled shape on their outer side to facilitate the insertion of the clip 1 onto the wiper arm 100. The angle of the bevel shape is, for example, 15° to 20°.

[0029] The V-shaped base of the clip 1 forms a reservoir 5 for a portion of the fluid conduit 102. Protrusions 7a and 7b may be formed on the inner wall of the V-shape to define the reservoir and prevent any interference with the fluid conduit 102 when the clip 1 is mounted on the wiper arm 100. The protrusions 7a and 7b extend at an angle of, for example, 90° to 120° (from the wall of the V-shape), and their height is, for example, 0.1 to 0.3 times the diameter of the fluid conduit 102, thereby allowing a portion of the fluid conduit 102 to be easily inserted into the reservoir 5 while still ensuring that the portion remains within the reservoir 5. The ends of the protrusions 7a and 7b may have a rounded shape. Figure 2 A schematic diagram shows a portion of the fluid conduit 102 positioned within the container 5.

[0030] As needed, the protrusions 7a and 7b can either allow the fluid conduit to slide or clamp the fluid conduit, which will enable the clips to be held in place on the fluid conduit.

[0031] The various corners of clip 1, especially the corners of the V-shaped part, can be rounded, such as... Figures 1 to 3 As shown in the embodiment. Furthermore, the wall thickness of the clip 1 can vary. The base of the V-shape can have a wall thinner than the two side walls, thus providing elasticity and allowing the two ends of the V-shape to be easily separated. The retaining arms 3a, 3b can also have a small thickness to facilitate positioning on the wiper arm 100.

[0032] Preferably, the clip 1 is made of plastic material, particularly ethylene propylene.

[0033] The present invention also relates to a method of attaching a fluid conduit 102 to a wiper arm 100 of an injection system of a motor vehicle using one or more clips 1 as described above. Figure 4 The steps of the method are shown.

[0034] Step 101 involves providing one or more clips.

[0035] The second step 102 involves placing a portion of the fluid conduit 102 into the housing 5 of the clamp 1 as described above, specifically by separating the ends of the V-shape or by sliding the fluid conduit into the V-shape. The clamp 1 is positioned such that the opening of the clamp 1 between the retaining arms 3a, 3b contacts the fluid conduit 102, and then the ends of the V-shape are separated by pressing the outer portion of the base of the clamp 1 in the direction of the fluid conduit 102, thereby allowing the fluid conduit 102 to be inserted into the clamp 1, specifically into the housing 5. Figure 2 As shown, the second step 102 ends when this part of the fluid conduit 102 is positioned in the container 5.

[0036] The third step 103 involves placing the retaining arms 3a, 3b against the wiper arm 100, and pushing the clip 1 against the wiper arm 100 so that, after the end of the clip 1 has been opened, a portion of the wiper arm 100 can be inserted into the V-shape, that is, between the receiver 5 and the retaining arms 3a, 3b. Figure 3 As indicated by the arrow, the clip 1 is placed on the wiper arm 100.

[0037] If multiple clips 1 are required for attachment, steps 102 and 103 can be repeated for each clip 1. The order of these steps can be different; for example, all clips 1 can be placed on the hydraulic line 102 and then each clip 1 can be attached to the wiper arm 100; or, the clips 1 can be positioned one after another on the hydraulic line 102 and the wiper arm 100.
