Description

Field of the Invention

[0001] The present invention relates to a fluid connection system for a cleaning system for motor vehicles and vehicles, in particular motor vehicles, the cleaning system comprising tubes, nozzles and a fluid connection system according to the invention. Background of the Invention

[0002] The fluid connection system of a cleaning system for motor vehicles serves to connect a plurality of tubes via the fluid connection system. Here, a correct connection is mandatory for the function of the cleaning system. If the tubes are connected incorrectly, the cleaning system may not work or, in the worst case, may be damaged because the wrong fluid and / or the wrong pressure is applied to the tubes.

[0003] Therefore, it is very important to ensure that the connecting parts are connected correctly. Here, in the prior art, tubes and connecting parts of different diameters are used. A system is known from US 7,472,929 B2 which comprises two connecting parts with different outer diameters. Accordingly, the tubes connected to the two connecting parts also have different inner diameters. In this way, it is ensured that the tubes are correctly connected to the connecting parts.

[0004] US 7,472,929 B2 discloses a system having at least two connecting parts. Here, the outer diameter of each connecting part varies with the length of the connecting part. Accordingly, tubes with different inner diameters can be connected to the connecting parts.

[0005] However, in the prior art, tubes with different inner diameters are required. Due to the different diameters, the flow rate, the pressure and / or the volume flow rate change. Therefore, the known system complicates the rule of uniform fluid flow through all tubes.

[0006] In addition, the inner diameter of the tubes varies only slightly, so that errors often occur during the assembly of the tubes. Although the tubes and the connecting parts have different diameters, an incorrect connection can still be established by applying too much force to the tubes during the connection process. Therefore, the fluid connection system does not work or may be damaged.

[0007] Based on this prior art, it is an object of the present invention to provide a durable and cost-effective fluid connection system which is an error-proof system and easy to assemble, while at the same time the fluid connection system guarantees the function of the fluid connection system and uniform fluid flow. Summary of the Invention

[0008] According to a first aspect of the present invention, the above object is solved by a fluid connection system for an automotive cleaning system, wherein the fluid connection system comprises at least two connectors, wherein each of the at least two connectors comprises a male connector and a female connector, wherein for each of the at least two connectors, the male connector comprises an outlet opening and the female connector comprises an inlet opening, wherein for each of the at least two connectors, the male connector and the female connector are configured to fluidly connect the outlet opening to the inlet opening in an assembled state, wherein for each of the at least two connectors, the length of the male connector is adapted to the length of the female connector, and wherein for each of the at least two connectors, the lengths are different.

[0009] The fluid connection system provides the advantage that the fluid connection system can prevent misconnection, thus ensuring the function of the fluid connection system. Therefore, the fluid connection system provides good durability. In addition, since the lengths are the same, only the correct male connector and the correct female connector can be connected, so the fluid connection system is easy to assemble. Moreover, the fluid connection system provides uniform fluid flow. Further, the fluid connection system can be cost-effective.

[0010] The fluid connection system can be a system for supplying fluid from a central supply source to various fluid outlets. The various fluid outlets can be, for example, nozzles of a cleaning system. The fluid connection system can be configured to provide uniform fluid flow through all pipes. For example, the cleaning system can be configured to clean the windshield, sensors, and / or headlights.

[0011] The at least two connectors can be, for example, a fluid connection of a pipe or a fluid connection between a pipe and a distributor. The at least two connectors can be configured to fluidly connect, for example, a pipe or a pipe and a distributor.

[0012] The male connector can have a protruding portion that can be inserted into a receiving space of the female connector. The shape of the male connector can be adapted to the shape of the female connector.

[0013] The outlet opening can be configured to output the fluid that can be within the fluid connection system. The inlet opening can be configured to receive the fluid that can be within the fluid connection system. The outlet opening and the inlet opening can have the same cross-section. The outlet opening can be arranged at an end of the male connector. The inlet opening can be arranged to be spaced apart from an end of the female connector. In particular, the inlet opening can be arranged to be spaced apart from the end of the female connector into which the male connector can be inserted.

[0014] The male connector and the female connector are configured to fluidly connect the outlet opening to the inlet opening in the assembled state. The assembled state can be a state in which the male connector and the female connector can be connected to each other, in particular in a form-fitting and / or force-fitting manner. The outlet opening and the inlet opening can be fluidly connected if fluid can be transferred from the outlet opening to the inlet opening without loss of part of the fluid.

[0015] The length of the male connector is adapted to the length of the female connector. The length of the male connector can be the length of the protruding part of the male connector that can be inserted into the female connector, in particular into the 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 to lock to each other only if the lengths of the male connector and the female connector can be the same.

[0016] For each of at least two connecting elements, the lengths are different. For example, there can be only one male connector and one female connector with the same length. The length of the male connector of the first of the at least two connecting elements can be different from the length of the male connector of the second of the at least two connecting elements and from the length of the female connector of the second of the at least two connecting elements. That the lengths are different for each of at least two connecting elements can mean that for each of at least two connecting elements, the lengths of the male connectors of the at least two connecting elements can be different and that for each of at least two connecting elements, the lengths of the female connectors of the at least two connecting elements can be different.

[0017] For example, a fluid connection system may include at least two connection members, wherein a first connection member of the at least two connection members may include a first male connector and a first female connector, wherein the first male connector may be configured to be fluidly connected to the first female connector, wherein the first male connector may include an outlet opening and at least one restricting element, wherein the at least one restricting element may be arranged in front of the outlet opening in the flow direction, wherein the first female connector may include an inlet opening and at least one constraining device, wherein the at least one constraining device may be arranged in front of the inlet opening in the flow direction, wherein in the assembled state, the at least one constraining device may abut against the at least one restricting element, wherein in the assembled state, the outlet opening may be connected to the inlet opening, and wherein a second connection member of the at least two connection members may include a second male connector and a second female connector, wherein the second male connector may be configured to be fluidly connected to the second female connector, wherein the second male connector may include an outlet opening and at least one restricting element, wherein the at least one restricting element may be arranged in front of the outlet opening in the flow direction, wherein the second female connector may include an inlet opening and at least one constraining device, wherein the at least one constraining device may be arranged in front of the inlet opening in the flow direction, wherein in the assembled state, the at least one constraining device may abut against the at least one restricting element, wherein in the assembled state, the outlet opening may be connected to the inlet opening, wherein the length from the at least one restricting element to the outlet opening may correspond to the distance from the at least one constraining device to the inlet opening, and wherein the length of the first connection member of the at least two connection members may be different from the length of the second connection member of the at least two connection members.

[0018] In an embodiment, the male connector of one of the at least two connection members can only be mated with the female connector of the same connection member among the at least two connection members.

[0019] In this way, the fluid connection system can prevent misassembly, thus ensuring the function of the fluid connection system. In addition, since only the male and female connectors can be correctly connected, the fluid connection system can be easily assembled. In addition, the fluid connection system can provide uniform fluid flow.

[0020] One connection member and the same connection member can be the same connection member. One connection member can be one of the at least two connection members. In particular, since their lengths are all different, all connection members can be different from each other, thus one connection member can be one of the at least two connection members. For one or rather the same connection member, the length of the male connector can correspond to the length of the female connector.

[0021] In an embodiment, the male connector may include at least one restricting element, wherein the at least one restricting element may be spaced apart from the outlet opening, wherein the female connector may include at least one restraining means, wherein the at least one restraining means may be spaced apart from the inlet opening, and wherein the length may be the distance from the at least one restricting element to the outlet opening and the distance from the at least one restraining means to the inlet opening.

[0022] [[ID=*3]]In this way, the fluid connection system can be error-proof, and thus the function of the fluid connection system can be ensured. In addition, due to the at least one restricting element and the at least one restraining means, only the male connector and the female connector can be correctly connected, so that the fluid connection system can be easily assembled. In addition, the fluid connection system can provide uniform fluid flow.

[0023] The at least one restricting element may be configured to restrict the movement of the male connector into the female connector, particularly into the receiving space of the female connector. The movement of the male connector into the female connector may be along the flow direction of the fluid in the fluid connection system. To restrict the movement of the male connector, the at least one restricting element may have a contact surface that may interact with the female connector, particularly with the at least one restraining means. The at least one restricting element may contact the surface of the female connector, so that due to the contact, the movement of the male connector into the female connector, particularly into the receiving space of the female connector, can be restricted.

[0024] The male connector may include at least one restricting element, which means that the male connectors of at least two connecting members may each include at least one restricting element.

[0025] The female connector may include at least one restraining means, which means that the female connector of at least one of the at least two connecting members may include at least one restraining means.

[0026] The length may be the distance from the at least one restricting element to the outlet opening and the distance from the at least one restraining means to the inlet opening, which means that the length of each male connector of at least two connecting members may be the distance from the at least one restricting element to the outlet opening, and wherein the length of the female connector of at least one of the at least two connecting members may be the distance from the at least one restraining means to the inlet opening.

[0027] At least one restraint device may be configured to restrict the movement of the male connector into the female connector, in particular the movement into the receiving space of the female connector. The movement of the male connector into the female connector may be along the flow direction of the fluid of the fluid connection system. To restrict the movement of the male connector, at least one restraint device may have a contact surface that may interact with the male connector, in particular at least one limiting element. At least one restraint device may contact the surface of the male connector, and thus, due to the contact, may restrict the movement of the male connector into the female connector, in particular into the receiving space of the female connector.

[0028] At least one limiting element and at least one restraint device may be configured to restrict the movement of the male connector into the female connector, in particular the movement into the receiving space of the female connector, in a form-fitting manner. For example, the contact surface of at least one limiting element may contact the contact surface of at least one restraint device to restrict the movement of the male connector into the female connector. For example, the contact surface may face the outlet opening and / or the contact surface may face the inlet opening.

[0029] At least one limiting element may be spaced apart from the outlet opening. For example, at least one limiting element may be arranged in front of the outlet opening in the flow direction. In particular, at least one limiting element and the outlet opening may be separated.

[0030] At least one restraint device may be spaced apart from the inlet opening. For example, at least one restraint device may be arranged in front of the inlet opening in the flow direction. In particular, at least one restraint device and the inlet opening may be separated.

[0031] In an embodiment, at least one limiting element may have an outer diameter, wherein for each male connector of at least two connectors, the outer diameter of at least one limiting element may be different, wherein the female connector of at least one of the at least two connectors may include an insertion space, wherein the insertion space may be arranged between at least one restraint device and the open end of the female connector of at least one of the at least two connectors, wherein the insertion space may have an inner diameter, and wherein the inner diameter of the insertion space of the female connector of at least one of the at least two connectors may be the same as the inner diameter of at least one limiting element of the male connector of the same connector of the at least two connectors only.

[0032] By doing so, the fluid connection system may provide the advantage that the fluid connection system can prevent misconnection, and thus the function of the fluid connection system can be ensured. Therefore, good durability of the fluid connection system can be ensured. In addition, since only the correct male connector and the correct female connector can be connected, the fluid connection system can be easily assembled. In addition, the fluid connection system may be cost-effective.

[0033] The outer diameter of at least one restricting element can be the spatial extent of the at least one restricting element transverse to, in particular perpendicular to, the fluid flow direction. The outer diameter of at least one restricting element can be the spatial extent of the at least one restricting element transverse to, in particular perpendicular to, the direction connecting the male connector and the female connector. The outer diameter can be the distance between two outer edges of the at least one restricting element connected via the center of the at least one restricting element.

[0034] The insertion space can be the area into which a part of the male connector is inserted. The insertion space can be part of the receiving space. The insertion space can be arranged between at least one restraining means and the open end. The at least one restraining means can be a restraining means that interacts with at least one restricting element. The open end can be the open end of the female connector into which the male connector can be inserted.

[0035] The inner diameter of the insertion space can be the spatial extent of the insertion space transverse to, in particular perpendicular to, the fluid flow direction. The inner diameter of the insertion space can be the spatial extent of the insertion space transverse to, in particular perpendicular to, the direction connecting the male connector and the female connector. The inner diameter can be the distance between two inner walls of the insertion space connected via the center of the insertion space.

[0036] The inner diameter of the insertion space of the female connector of at least one of the at least two connecting elements can be the same only as the outer diameter of at least one restricting element of the male connector of the same connecting element among the at least two connecting elements. Thus, only at least one restricting element having an outer diameter the same 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, enabling insertion of the male connector into the female connector.

[0037] In an embodiment, in the assembled state, at least one restraining means can abut against at least one restricting element, and / or wherein in the assembled state, the outlet opening can be adjacent to the inlet opening.

[0038] If in the assembled state at least one restraining means can abut against at least one restricting 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 easy. In addition, the assembly can be error-proof because correct assembly can be easily checked.

[0039] If in the assembled state the outlet opening can be adjacent to the inlet opening, the fluid connection system can provide a uniform fluid flow.

[0040] If, in the assembled state, at least one restraint device can bear against at least one limiting element, and if, in the assembled state, the outlet opening can be adjacent to the inlet opening, then the fluid connection system can be very effective because correct assembly can be ensured while good fluid connection can be guaranteed. In addition, since, in the assembled state, at least one restraint device can bear against at least one limiting element, and since, 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.

[0041] In the assembled state, at least one restraint device can bear against at least one limiting element. Thus, the contact surface of at least one limiting element can contact the contact surface of at least one restraint device to limit the movement of the male connector into the female connector.

[0042] In the assembled state, the outlet opening can be adjacent to the inlet opening. Thus, the outlet opening can be very close to the inlet opening, so that good fluid flow from the outlet opening to the inlet opening can be ensured. This can mean that no liquid will be lost.

[0043] In an embodiment, the inner diameter of the outlet opening and the inner diameter of the inlet opening can be the same, especially for all the connectors of at least two connectors.

[0044] By doing so, the fluid flow within the fluid connection system can be uniform, and thus, due to the uniform fluid flow, the efficiency of the fluid connection system can be improved. For all the connectors of at least two connectors, if the inner diameter of the outlet opening and the inner diameter of the inlet opening can be the same, then the fluid flow within the entire fluid connection system can be uniform, and thus, due to the uniform fluid flow, the efficiency of the fluid connection system can be further improved.

[0045] The inner diameter can be the length of a straight line passing from one side of the outlet opening, through the center of the outlet opening, to the opposite side of the outlet opening. The inner diameter can be the length of a straight line passing from one side of the inlet opening, through the center of the inlet opening, to the opposite side of the inlet opening. For all the connectors of at least two connectors, if the inner diameter of the outlet opening and the inner diameter of the inlet opening can be the same, then each outlet opening of all the male connectors of the fluid connection system and each inlet opening of all the female connectors of the fluid connection system can be the same.

[0046] In an embodiment, the male connector can be detachably connected to the female connector, and / or the male connector can be connected to the female connector in a form - locking and / or force - locking manner.

[0047] If the male connector can be detachably connected to the female connector, the components of the fluid connection system can be easily replaced. Thus, the durability of the fluid connection system can be improved.

[0048] Assembly can be made very easy if the male connector can be connected to the female connector in a form - locking and / or force - locking manner.

[0049] If the male connector can be detachably connected to the female connector and the male connector can be connected to the female connector in a form - locking and / or force - locking manner, the connection of the female connector can be very durable and easy to close and open. Thus, the assembly and disassembly of the fluid connection system can be very easy, thereby improving durability.

[0050] The male connector can be detachably connected to the female connector so that the male connector can be detached from the female connector without damage.

[0051] In an embodiment, the female connector can include an opening that extends at least partially from an inlet opening to at least one restraint device. In particular, a fixing element can be arranged within the opening. In particular, in the assembled state, the fixing element can fix the male connector to the female connector, in particular in a form - locking and / or force - locking manner.

[0052] If the female connector can include an opening that extends at least partially from an inlet opening to at least one restraint device, the female connector can be light, and thus the handling and assembly of the fluid connection system can be very easy.

[0053] If the female connector can include an opening that extends at least partially from an inlet opening to at least one restraint device, in particular a fixing element can be arranged within the opening, and in particular in the assembled state, the fixing element can fix the male connector to the female connector, in particular in a form - locking and / or force - locking manner, the male connector can be easily connected to the female connector. In addition, the fixing element can be arranged within the opening, so the fixing element can be visible. Thus, the connection between the male connector and the female connector can be inspected. In addition, the fixing element can be used for assembly. Thus, the assembly of the fluid connection system can be simplified.

[0054] The opening can be a material extraction opening within the female connector. The opening can connect the interior of the female connector to the exterior of the female connector. The opening can extend at least partially from the inlet opening to at least one restraint device. Thus, at least one opening can be arranged in front of the inlet opening so that fluid flow is not obstructed by the opening. In particular, in the assembled state, the outlet opening of the male connector can be arranged behind the opening in the flow direction.

[0055] The fixing element can be arranged within the opening. In particular, the fixing element can be arranged within two openings, where the two openings are arranged on opposite sides of the female connector, where the fixing element can have two activation surfaces, where the activation surfaces can be arranged within the two openings, where the fixing element can have two arched members, where each arched member can connect the end of one activation surface to the end of the other activation surface, and where the arched members can be configured to move to the outside of the female connector when the two activation surfaces are pressed into the interior of the female connector.

[0056] For example, the two arched members can each have retaining means, and the male connector can have two receiving means, where in the assembled state, the retaining means can interact with the receiving means to fix the male connector within the female connector.

[0057] In an embodiment, the female connector can include a sealing element, particularly a D-ring, where the sealing element can be arranged at the inlet opening.

[0058] If the female connector includes a sealing element, the fluid flow from the male connector to the female connector can be improved, such that the fluid connection system can provide very good fluid flow. If the sealing element is a D-ring, the connection between the outlet opening and the inlet opening can be impermeable, thus further enhancing the fluid flow of the fluid connection system.

[0059] The sealing element can be, for example, an O-ring. The D-ring can have the shape of a D, where the flat surface can press against the surface of the female connector, and the arched surface can point towards the center of the female connector.

[0060] In an embodiment, the male connector can be integral.

[0061] In this way, the male connector can be very durable, and the male connector can be produced in a very cost-effective manner. Thus, the fluid connection system can be very durable and cost-effective.

[0062] Integral can mean that the male connector can be made in one piece.

[0063] In an embodiment, the fluid connection system can include a valve, where the valve can be fluidly connected to at least two connectors.

[0064] By doing so, the fluid connection system can provide a very uniform fluid flow. The valve can be configured to regulate the fluid flow through each of the at least two connectors. The valve can be arranged along the flow direction before the connectors.

[0065] In an embodiment, the fluid connection system can be designed for a fluid pressure from 5 bar to 12 bar, particularly from 8 bar to 12 bar.

[0066] By doing so, the fluid connection system can provide very good fluid flow. For example, the fluid flow is sufficient for the cleaning system of an automobile.

[0067] In this way, the fluid connection system can have the advantage that the fluid connection system can prevent misassembly, thus ensuring the function of the fluid connection system. Therefore, the fluid connection system can provide good durability. In addition, since the lengths are the same, only the male connector and the female connector can be connected, so the fluid connection system can be easily assembled. In addition, the fluid connection system can provide uniform fluid flow. In addition, the fluid connection system can be cost-effective.

[0068] In an embodiment, the male connector and the female connector of each of at least two connecting members can have corresponding rotational symmetries.

[0069] By doing so, another anti-misassembly system can be added, thus further improving and simplifying the correct assembly. Therefore, the function of the fluid connection system can be ensured. Therefore, the fluid connection system can have good durability. In addition, since only the male connector and the female connector can be connected with the same rotational symmetry, the fluid connection system can be easily assembled. In addition, the fluid connection system can be cost-effective because the additional rotational symmetry can be produced cost-effectively.

[0070] Rotational symmetry can be the property that a shape looks the same after a partial rotation. The degree of rotational symmetry of the male connector and the female connector can be the number of different orientations in which they look exactly the same with each rotation.

[0071] In an embodiment, the rotational symmetry can be achieved by a rotationally symmetric cross-section, where in particular, the rotationally symmetric cross-section can be achieved by a notch and / or a polygonal cross-section.

[0072] In this way, another anti-misassembly system can be added, thus facilitating the correct assembly. Therefore, the function of the fluid connection system can be ensured. Therefore, the fluid connection system can provide good durability. In addition, since only the male connector and the female connector can be connected with the same rotational symmetry, the fluid connection system can be easily assembled. In addition, the fluid connection system can be cost-effective because the additional rotational symmetry can be cost-effective.

[0073] The rotationally symmetric cross-section can be the cross-section of the male connector and the female connector perpendicular to the flow direction. The polygonal cross-section can be in the shape of, for example, a rectangle, a triangle or a square, which can correspond to a degree of rotational symmetry of two, three or four respectively. By means of a notch, a degree of rotational symmetry can be achieved.

[0074] In an embodiment, the fluid connection system can consist of three connecting members.

[0075] The fluid connection system provides the advantage that the fluid connection system is error-proof, thus ensuring the function of the fluid connection system. Therefore, the fluid connection system can provide good durability. In addition, since the lengths are the same, only the male connector and the female connector can be connected, so the fluid connection system can be easily assembled. Moreover, the fluid connection system can provide uniform fluid flow. Additionally, the fluid connection system can be cost-effective. In particular, through three connecting pieces, a very good fluid supply can be ensured, such as for a cleaning system in a vehicle.

[0076] According to a second aspect of the present invention, the above object is solved by a vehicle, in particular an automobile, which includes a pipe, a nozzle, and the fluid connection system according to the present invention, wherein the pipe, the nozzle, and the fluid connection system are fluidly connected.

[0077] The fluid connection system provides the advantage that the fluid connection system is error-proof, thereby ensuring the function of the fluid connection system. Therefore, the fluid connection system and thus the vehicle provide good durability. In addition, since the lengths are the same, only the male connector and the female connector can be connected, so the fluid connection system and thus the vehicle are also easily assembled. Moreover, the fluid connection system provides uniform fluid flow. Therefore, a very good fluid flow distribution is provided in the vehicle. Additionally, the fluid connection system and thus the vehicle are cost-effective.

[0078] According to a third aspect of the present invention, the above object is solved by using the fluid connection system of the present invention in a cleaning system.
