Description

FIELD OF THE INVENTION

[0001] The present invention relates to a fluid connection system for a cleaning system of an automobile and a vehicle, in particular an automobile, comprising a pipe, a nozzle and the fluid connection system according to the invention. BACKGROUND OF THE INVENTION

[0002] A fluid connection system for an automotive cleaning system is used to connect multiple pipes through the fluid connection system. Proper connection is essential for the cleaning system to function. If the pipes are connected incorrectly, the cleaning system may not function or, in the worst case, be damaged due to the pipes being exposed to the wrong fluid and / or the wrong pressure.

[0003] Therefore, it is important to ensure that the connections are correctly connected. In the prior art, different diameters of the pipe and the connector are used. US Pat. No. 7,472,929 B2 discloses a system that includes two connectors with different outer diameters. Consequently, the pipes connected by the two connectors also have different inner diameters. This ensures that the pipes are correctly connected to the connectors.

[0004] US 7,472,929 B2 discloses a system with at least two connectors. Here, the outer diameter of each connector varies along the length of the connector. This allows pipes with different inner diameters to be connected to the connectors.

[0005] US 4 953 592 A discloses a self-sealing coupling with bypass for the hydraulic circuit.

[0006] However, the current technology requires pipes with different inner diameters. These different diameters result in variations in flow, pressure, and / or volumetric flow. Therefore, the existing systems make it difficult to control a uniform fluid flow through all pipes.

[0007] In addition, the inner diameters of the pipes vary only slightly, so errors regularly occur during pipe assembly. Even though the pipes and fittings have different diameters, it is still possible to create an incorrect connection by applying too much force to the pipe during connection. The result is that the fluid connection system malfunctions or may be damaged.

[0008] In view of this state of the art, it is the object of the invention to provide a durable and cost-effective fluid connection system that is a fail-safe system and is easy to assemble, wherein the fluid connection system simultaneously ensures the function of the fluid connection system and a uniform fluid flow. SUMMARY OF THE INVENTION

[0009] According to a first aspect of the invention, the above-mentioned object is achieved by a fluid connection system for a cleaning system of an automobile, wherein the fluid connection system comprises at least two connections, wherein each of the at least two connections comprises a male connector and a female connector, wherein in each of the at least two connections the male connector comprises an outlet opening and the female connector comprises an inlet opening, wherein in each of the at least two connections the male connector and the female connector are designed to fluidically connect the outlet opening to the inlet opening in an assembled state, wherein in each of the at least two connections the length of the male connector is adapted to the length of the female connector, wherein the length is different for each of the at least two connections.

[0010] The fluid connection system offers the advantage of being fail-safe, ensuring its functionality. Consequently, the fluid connection system enables a long service life. Furthermore, the fluid connection system is easy to install, as only the correct male and female connectors can be connected due to their equal length. Furthermore, the fluid connection system enables consistent fluid flow. Furthermore, the fluid connection system can be cost-effective.

[0011] The fluid connection system can be a system for supplying a fluid from a central source to various fluid outlets. The various fluid outlets can, for example, be nozzles of a cleaning system. The fluid connection system can be configured to enable a uniform fluid flow through all pipes. For example, the cleaning system can be configured to clean a windshield, a sensor, and / or a headlight.

[0012] The at least two connections can be a fluid connection, for example, between pipes or between a pipe and a distributor. The at least two connections can be designed to fluidically connect pipes or a pipe and a distributor, for example.

[0013] The male connector may have a protruding part that can be inserted into a receiving space of the female connector. The shape of the male connector may be adapted to the shape of the female connector.

[0014] The outlet opening may be configured to discharge a fluid that may be located within the fluid connection system. The inlet opening may be configured to receive a fluid that may be located within the fluid connection system. The outlet opening and the inlet opening may have the same cross-section. The outlet opening may be arranged at the end of the male connector. The inlet opening may be arranged at a distance from an end of the female connector. In particular, the inlet opening may be arranged at a distance from an end of the female connector into which the male connector can be inserted.

[0015] The male connector and the female connector are configured to fluidically connect the outlet opening to the inlet opening in an assembled state. The assembled state can be the state in which the male connector and the female connector can be connected to one another, in particular in a form-fitting and / or force-fitting manner. The outlet opening and the inlet opening can be fluidically connected if fluid can be transferred from the outlet opening to the inlet opening without losing any of the fluid.

[0016] The length of the male connector is adapted to the length of the female connector. The length of the male connector can be the protruding part of the male connector, which can be inserted into the female connector, in particular into a receiving space of the female connector. The length of the female connector can be the length of the receiving space of the female connector into which the male connector can be inserted. The male connector and the female connector can be configured such that they only lock into each other if the length of the male connector and the female connector can be the same.

[0017] The length is different for each of the at least two connections. For example, the length may only be the same for one male connector and one female connector. The length of the male connector of the first connection of the at least two connections may differ from the length of the male connector of the second connection of the at least two connections and the length of the female connector of the second connection of the at least two connections.

[0018] For example, the fluid connection system may comprise at least two connections, wherein the first connection of the at least two connections may comprise a first male connector and a first female connector, wherein the first male connector may be configured to be fluidically connected to the first female connector, wherein the first male connector may comprise an outlet opening and at least one limiting element, wherein the at least one limiting element may be arranged upstream of the outlet opening in the flow direction, wherein the first female connector may comprise an inlet opening and at least one limiting means, wherein the at least one limiting means may be arranged upstream of the inlet opening in the flow direction, wherein in the assembled state, the at least one limiting means may bear against the at least one limiting element,wherein, in the assembled state, the outlet opening can be connected to the inlet opening, and wherein the second connection of the at least two connections can comprise a second male connector and a second female connector, wherein the second male connector can be designed to be fluidically connected to the second female connector, wherein the second male connector can comprise an outlet opening and at least one limiting element, wherein the at least one limiting element can be arranged upstream of the outlet opening in the flow direction, wherein the second female connector can comprise an inlet opening and at least one limiting means, wherein the at least one limiting means can be arranged upstream of the inlet opening in the flow direction, wherein, in the assembled state, the at least one limiting means can bear against the at least one limiting element,wherein in the assembled state, the outlet opening can be connected to the inlet opening, wherein the length from the at least one limiting element to the outlet opening can correspond to the distance from the at least one limiting means to the inlet opening, and wherein the length of the first of the at least two connections can be different from the length of the second of the at least two connections.

[0019] In one embodiment, the male connector of one connection of the at least two connections can only mate with the female connector of the same connection of the at least two connections.

[0020] In this way, the fluid connection system can be fail-safe, ensuring its functionality. Furthermore, the fluid connection system can be easy to install, as only the male and female connectors can be correctly connected. Furthermore, the fluid connection system can ensure a consistent fluid flow.

[0021] The one connection and the same connection may be the same connection. The one connection may be one of the at least two connections. In particular, all connections may be different from one another because they all differ in length, so that the one connection may be one of the at least two connections. In the one or the same connection, the length of the male connector may correspond to the length of the female connector.

[0022] The male connector comprises at least one limiting element, wherein the at least one limiting element is spaced from the outlet opening, wherein the female connector comprises at least one limiting means, wherein the at least one limiting means is spaced from the inlet opening, wherein the length is the distance from the at least one limiting element to the outlet opening and from the at least one limiting means to the inlet opening.

[0023] In this way, the fluid connection system can be fail-safe, ensuring its functionality. Furthermore, the fluid connection system can be easy to install, since the at least one limiting element and the at least one limiting means ensure that only the male connector and the female connector can be correctly connected. Furthermore, the fluid connection system can enable a uniform fluid flow.

[0024] The at least one limiting element can be designed to limit a movement of the male connector into the female connector, in particular into the receiving space of the female connector. The movement of the male connector into the female connector can occur along the flow direction of the fluid of the fluid connection system. In order to limit the movement of the male connector, the at least one limiting element can have a contact surface that can interact with the female connector, in particular with the at least one limiting means. The at least one limiting element can have contact with the surface of the female connector such that, due to the contact, the movement of the male connector into the female connector, in particular into the receiving space of the female connector, can be limited.

[0025] The at least one limiting means can be designed to limit a movement of the male connector into the female connector, in particular into the receiving space of the female connector. The movement of the male connector into the female connector can occur along the flow direction of the fluid of the fluid connection system. In order to limit the movement of the male connector, the at least one limiting means can have a contact surface that can interact with the male connector, in particular with the at least one limiting element. The at least one limiting means can have contact with the surface of the male connector, such that the movement of the male connector into the female connector, in particular into the receiving space of the female connector, can be limited due to the contact.

[0026] The at least one limiting element and the at least one limiting means can be configured to limit the movement of the male connector into the female connector, in particular into the receiving space of the female connector, in a form-fitting manner. For example, the contact surface of the at least one limiting element can touch the contact surface of the at least one limiting means to limit the movement of the male connector into the female connector. For example, the contact surface can face the outlet opening and / or the contact surface can face the inlet opening.

[0027] The at least one limiting element can be spaced apart from the outlet opening. For example, the at least one limiting element can be arranged upstream of the outlet opening in the flow direction. In particular, the at least one limiting element and the outlet opening can be separated from one another.

[0028] The at least one limiting means can be spaced apart from the inlet opening. For example, the at least one limiting means can be arranged upstream of the inlet opening in the flow direction. In particular, the at least one limiting means and the inlet opening can be separated from one another.

[0029] The at least one limiting element has an outer diameter, wherein the outer diameter of the at least one limiting element is different for each male connector of the at least two connections, wherein the female connector of at least one of the at least two connections comprises an insertion space, wherein the insertion space is arranged between the at least one limiting means and an open end of the female connector of at least one of the at least two connections, wherein the insertion space has an inner diameter, wherein the inner diameter of the insertion space of the female connector of at least one of the at least two connections is equal to the outer diameter of only the at least one limiting element of the male connector of the same connection of the at least two connections.

[0030] This allows the fluid connection system to offer the advantage of being fail-safe, thus ensuring its functionality. This ensures the longevity of the fluid connection system. Furthermore, the fluid connection system can be easy to install, as only the correct male and female connectors can be connected. Furthermore, the fluid connection system can be cost-effective.

[0031] The outer diameter of the at least one boundary element can be the spatial extent of the at least one boundary element transversely, in particular at a right angle, to the flow direction of the fluid. The outer diameter of the at least one boundary element can be the spatial extent of the at least one boundary element transversely, in particular at a right angle, to the direction for connecting the male connector to the female connector. The outer diameter can be the distance between two outer edges of the at least one boundary element that are connected via the center of the at least one boundary element.

[0032] The insertion space may be an area into which a part of the male connector is inserted. The insertion space may be part of the receiving space. The insertion space may be arranged between the at least one limiting means and the open end. The at least one limiting means may be the limiting means that cooperates with the at least one limiting element. The open end may be the open end of the female connector into which the male connector can be inserted.

[0033] The inner diameter of the insertion chamber can be the spatial extension of the insertion chamber transversely, in particular at a right angle, to the direction of fluid flow. The inner diameter of the insertion chamber can be the spatial extension of the insertion chamber transversely, in particular at a right angle, to the direction for connecting the male connector to the female connector. The inner diameter can be the distance between two inner walls of the insertion chamber that are connected via the center of the insertion chamber.

[0034] The inner diameter of the insertion space of the female connector of at least one of the at least two connections can be equal to the outer diameter of only the at least one limiting element of the male connector of the same connection of the at least two connections. Consequently, only the at least one limiting element with the same outer diameter as the inner diameter can be inserted into the insertion space and thus into the female connector. The inner diameter and the outer diameter can be the same, whereby insertion of the male connector into the female connector may be possible.

[0035] In one embodiment, in the mounted state, the at least one limiting means can abut against the at least one limiting element, and / or wherein in the mounted state the outlet opening can be adjacent to the inlet opening.

[0036] If, in the assembled state, the at least one limiting means can rest against the at least one limiting element, the connection of the male connector and the female connector can be very simple. Thus, the assembly of the fluid connection system can be very simple. Furthermore, the assembly can be error-proof, as the correctness of the assembly can be easily verified.

[0037] If the outlet port can be adjacent to the inlet port in the assembled state, the fluid connection system can enable a uniform fluid flow.

[0038] If, in the assembled state, the at least one limiting means can abut the at least one limiting element, and wherein, in the assembled state, the outlet opening can be adjacent to the inlet opening, the fluid connection system can be very efficient, since correct assembly and, at the same time, a good fluid connection can be ensured. Furthermore, since, in the assembled state, the at least one limiting means can abut the at least one limiting element, and wherein, in the assembled state, the outlet opening can be adjacent to the inlet opening, the fluid connection system can be very well aligned and very reliable.

[0039] In the assembled state, the at least one limiting means can abut the at least one limiting element. Therefore, the contact surface of the at least one limiting element can contact the contact surface of the at least one limiting means to limit the movement of the male connector into the female connector.

[0040] In the assembled state, the outlet port can be adjacent to the inlet port. Consequently, the outlet port can be so close to the inlet port that a good fluid flow from the outlet port to the inlet port can be ensured. This can mean that no fluid can be lost.

[0041] In one embodiment, the inner diameter of the outlet opening and the inner diameter of the inlet opening may be the same, in particular for all of the at least two connections.

[0042] This allows the fluid flow within the fluid connection system to be uniform, so that the efficiency of the fluid connection system can be increased due to a uniform fluid flow. If the inner diameter of the outlet opening and the inner diameter of the inlet opening can be the same for all of the at least two connections, the fluid flow within the entire fluid connection system can be uniform, so that the efficiency of the fluid connection system can be further increased due to a uniform fluid flow.

[0043] The inner diameter may be the length of a straight line passing through the center of the outlet port from one side of the outlet port to an opposite side of the outlet port. The inner diameter may be the length of a straight line passing through the center of the inlet port from one side of the inlet port to an opposite side of the inlet port. If the inner diameter of the outlet port and the inner diameter of the inlet port can be the same for all of the at least two connections, each outlet port of all male connectors of the fluid connection system and each inlet port of all female connectors of the fluid connection system can be the same.

[0044] In one embodiment, the male connector can be releasably connected to the female connector, and / or the male connector can be connected to the female connector in a positive and / or non-positive manner.

[0045] If the male connector can be releasably connected to the female connector, parts of the fluid connection system can be easily replaced. This can increase the service life of the fluid connection system.

[0046] If the male connector can be connected to the female connector in a positive and / or force-locking manner, assembly can be very simple.

[0047] If the male connector can be releasably connected to the female connector, and the male connector can be connected to the female connector in a positive and / or frictional manner, the connection of the female connector can be very durable and easy to close and open. Consequently, assembly and disassembly of the fluid connection system can be very simple, and the service life can be increased.

[0048] The male connector can be detachably connected to the female connector so that the male connector can be detached from the female connector in a non-destructive manner.

[0049] In one embodiment, the female connector may comprise an opening which extends at least partially from the inlet opening to the at least one limiting means, wherein in particular a holding element may be arranged in the opening, wherein in particular in the assembled state the holding element may fasten the male connector to the female connector, in particular in a form-fitting and / or force-fitting manner.

[0050] If the female connector may comprise an opening extending at least partially from the inlet opening to the at least one restricting means, the female connector may be lightweight so that handling and therefore assembly of the fluid connection system may be very simple.

[0051] If the female connector can comprise an opening which extends at least partially from the inlet opening to the at least one limiting means, wherein in particular a retaining element can be arranged in the opening, wherein in particular in the assembled state the retaining element can fasten the male connector to the female connector, in particular in a form-fitting and / or force-fitting manner, the male connector can be easily fastened to the female connector. Furthermore, the retaining element can be arranged in the opening such that the retaining element can be visible. Consequently, it is possible to check the connection of the male connector to the female connector. Furthermore, the retaining element can be used for assembly. Consequently, the assembly of the fluid connection system can be simplified.

[0052] The opening may be a removal of material in the female connector. The opening may connect the interior of the female connector to the exterior of the female connector. The opening may extend at least partially from the inlet opening to the at least one restricting means. Consequently, the at least one opening may be arranged upstream of the inlet opening so that fluid flow through the opening cannot be obstructed. In particular, in the assembled state, the outlet opening of the male connector may be arranged downstream of the opening in the flow direction.

[0053] The retaining element can be arranged in the opening. In particular, the retaining element can be arranged in two openings, wherein the two openings are arranged on opposite sides of the female connector, wherein the retaining element can have two actuating surfaces, wherein the actuating surfaces can be arranged in the two openings, wherein the retaining element can have two arcs, wherein each arc can connect one end of one actuating surface to one end of the other actuating surface, wherein the arcs can be configured to move towards the exterior of the female connector when the two actuating surfaces can be pressed into the interior of the female connector.

[0054] For example, the two arches may each have a holding means, wherein the male connector may have two receiving means, wherein in the assembled state the holding means may cooperate with the receiving means to fix the male connector in the female connector.

[0055] In one embodiment, the female connector may comprise a sealing element, in particular a D-ring, wherein the sealing element may be arranged at the inlet opening.

[0056] If the female connector can include a seal, the fluid flow from the male connector to the female connector can be improved, allowing the fluid connection system to provide excellent fluid flow. If the sealing element is a D-ring, the connection between the outlet port and the inlet port can be impermeable, allowing the fluid flow of the fluid connection system to be further improved.

[0057] A sealing element can be an O-ring, for example. A D-ring can be shaped like a D, with the flat surface being able to be pressed against the surface of the female connector and the arc pointing toward the center of the female connector.

[0058] In one embodiment, the male connector may be monolithic.

[0059] This allows the male connector to be very durable and manufactured very cost-effectively. Thus, the fluid connection system can be very durable and cost-effective.

[0060] Monolithic can mean that the male connector can be formed as a single piece.

[0061] In one embodiment, the fluid connection system may comprise a valve, wherein the valve may be fluidly connected to the at least two connections.

[0062] This allows the fluid connection system to provide a very uniform fluid flow. The valve can be configured to regulate the fluid flow through each of the at least two connections. The valve can be arranged upstream of the connections in the flow direction.

[0063] In one embodiment, the fluid connection system can be designed for a fluid pressure of 5 bar, in particular 8 bar, to 12 bar.

[0064] This allows the fluid connection system to provide very good fluid flow. For example, the fluid flow may be sufficient for an automobile cleaning system.

[0065] In this way, the fluid connection system can offer the advantage of being fail-safe, thus ensuring the functionality of the fluid connection system. Consequently, the fluid connection system can provide a long service life. Furthermore, the fluid connection system can be easy to assemble, as only the male and female connectors can be connected due to their equal length. Furthermore, the fluid connection system can provide a uniform fluid flow. Furthermore, the fluid connection system can be cost-effective.

[0066] In one embodiment, the male connector and the female connector of each of the at least two connections may have matching rotational symmetry.

[0067] This further improves and simplifies correct assembly by adding another fail-safe system. Consequently, the functionality of the fluid connection system can be ensured. This allows the fluid connection system to have a long service life. Furthermore, the fluid connection system can be easy to assemble because only the male and female connectors can be connected with the same rotational symmetry. Furthermore, the fluid connection system can be cost-effective because additional rotational symmetry can be manufactured inexpensively.

[0068] Rotational symmetry can be the property that a shape can exhibit if it looks the same after a certain partial rotation of a full revolution. The degree of rotational symmetry of the male and female connectors can be the number of different orientations per revolution in which they can look exactly the same.

[0069] In one embodiment, the rotational symmetry can be realized by a rotationally symmetrical cross-section, wherein in particular the rotationally symmetrical cross-section can be realized by a notch and / or a polygonal cross-section.

[0070] This facilitates correct assembly by adding another fail-safe system. Consequently, the functionality of the fluid connection system can be ensured. This allows the fluid connection system to have a long service life. Furthermore, the fluid connection system can be easy to assemble, as only the male and female connectors can be connected with the same rotational symmetry. Furthermore, the fluid connection system can be cost-effective, as additional rotational symmetry can be manufactured inexpensively.

[0071] The rotationally symmetrical cross-section can be the cross-section of the male and female connectors at right angles to the flow direction. The polygonal cross-section can, for example, be in the shape of a rectangle, triangle, or square, which can correspond to a degree of rotational symmetry of two, three, or four, respectively. A notch can achieve a degree of rotational symmetry of one.

[0072] In one embodiment, the fluid connection system may consist of three connections.

[0073] The fluid connection system offers the advantage of being fail-safe, thus ensuring its functionality. Consequently, the fluid connection system can ensure a long service life. Furthermore, the fluid connection system can be easily assembled because only the male and female connectors can be connected due to their equal length. Furthermore, the fluid connection system can ensure a uniform fluid flow. Furthermore, the fluid connection system can be cost-effective. In particular, three connections can ensure a very good fluid supply, for example, for an automotive cleaning system.

[0074] According to a second aspect of the invention, the above-mentioned object is achieved by a vehicle, in particular an automobile, comprising a pipe, a nozzle and the fluid connection system according to the invention, wherein the pipe, the nozzle and the fluid connection system are fluidically connected.

[0075] The fluid connection system offers the advantage of being fail-safe, thus ensuring its functionality. Consequently, the fluid connection system and thus the vehicle have a long service life. Furthermore, the fluid connection system and thus the vehicle are easy to install, as only the male and female connectors can be connected due to their equal length. Furthermore, the fluid connection system enables uniform fluid flow. Consequently, a very good fluid flow distribution is achieved within the vehicle. Furthermore, the fluid connection system and thus the vehicle are cost-effective.

[0076] According to a third aspect of the invention, the above-mentioned object is achieved by using a fluid connection system according to the invention for a cleaning system.

DETAILED DESCRIPTION OF THE INVENTION

[0080] Fig. 1 shows a schematic view of a fluid connection system 2 for a cleaning system of an automobile. The fluid connection system 2 comprises three connections 4, each of the three connections 4 comprising a male connector 6 and a female connector 8. The female connectors 8 are not shown. In each of the three connections 4, the male connector 6 comprises an outlet opening 10, and the female connector 8 comprises an inlet opening 12. In each of the three connections 4, the male connector 6 and the female connector 8 are designed to fluidly connect the outlet opening 10 to the inlet opening 12 in an assembled state. In each of the three connections 4, the length of the male connector 6 is adapted to the length of the female connector 8. The length is different for each of the three connections 4.

[0081] The fluid connection system comprises a valve 24, wherein the valve 24 is fluidly connected to the three connections 4. The fluid connection system 2 is designed for a fluid pressure of 5 bar, in particular 8 bar, to 12 bar.

[0082] Fig. 2 shows a schematic view of a part of the fluid connection system 2. The fluid connection system 2 comprises three connections 4, each of the three connections 4 comprising a male connector 6 and a female connector 8. In each of the three connections 4, the male connector 6 comprises an outlet opening 10, and the female connector 8 comprises an inlet opening 12. In each of the three connections 4, the male connector 6 and the female connector 8 are designed to fluidly connect the outlet opening 10 to the inlet opening 12 in an assembled state. In each of the three connections 4, the length of the male connector 6 is adapted to the length of the female connector 8. The length is different for each of the three connections 4.

[0083] Fig. Figure 3 shows a schematic view of the three connections 4. Here, three different male connectors 6 are connected to the same female connector 6. Each male connector 6 comprises an outlet opening 10, and the female connector 8 comprises an inlet opening 12. In Fig. 3, the male connector 6 and the female connector 8 fit together on the left side. The male connector 6 and the female connector 8, which fit together, are designed to fluidly connect the outlet opening 10 to the inlet opening 12 in an assembled state. Here, with the male connector 6, which fits the female connector 8, the length of the male connector 6 is adapted to the length of the female connector 8.

[0084] As in Fig. 3, only the male connector 6 of the left connection 4 among the three connections 4 fits the female connector 8.

[0085] Each male connector 6 comprises limiting elements 14, wherein the limiting elements 14 are spaced from the outlet opening 10. The female connector 8 comprises limiting means 16, wherein the limiting means 16 are spaced from the inlet opening 12. The length is the distance from the limiting element 14 to the outlet opening 10 and from the limiting means 16 to the inlet opening 12.

[0086] In the assembled state, for the left connection 4, the limiting means 16 abut the limiting elements 14, and in the assembled state, the outlet opening 10 abuts the inlet opening 12.
