[0001] Solenoid valve module, valve block and method for producing a solenoid valve module

[0002] State of the art

[0003] The invention relates to a solenoid valve module according to the preamble of claim 1, a valve block according to claim 14 and a method according to the preamble of claim 15.

[0004] A solenoid valve module has already been proposed, at least comprising a module housing delimiting the solenoid valve module to the outside and at least one coil body arranged at least partially in the module housing for receiving at least one solenoid coil winding.

[0005] The object of the invention is, in particular, to provide a generic module with advantageous properties regarding the fixation of components in a module housing. This object is achieved according to the invention by the features of patent claim 1, while advantageous embodiments and further developments of the invention can be found in the subclaims.

[0006] Advantages of the invention

[0007] The invention is based on a solenoid valve module, at least comprising a module housing delimiting the solenoid valve module to the outside and at least one coil former arranged at least partially or completely in the module housing for accommodating at least one solenoid coil winding. It is proposed that the coil former is connected directly to an inner wall of the module housing in a non-destructive, non-detachable manner, i.e. in particular cannot be detachable without causing destruction, preferably mechanically. This makes it possible to advantageously fix components of the solenoid valve module in a module housing of the solenoid valve module. Advantageously, a particularly simple and / or cost-effective fixation can be achieved, in particular in comparison to the fixation known from the prior art by means of hold-down devices such as metal plates or metal brackets, which often have to be fastened with screws, rivets or the like.Advantageously, such hold-down devices and the like can be dispensed with. Advantageously, assembly can be simplified and / or accelerated. Furthermore, when several solenoid valves are fixed in a common solenoid valve housing, simple and reliable tolerance compensation can be achieved. Advantageously, in contrast to a common hold-down device or several separately fastened hold-down devices, for example, it can be ensured that all solenoid valves are fixed with essentially identical holding forces, in particular minimum forces. This advantageously makes it possible to achieve a high level of operational reliability. Advantageously, the risk of vibrations in individual solenoid valves in a solenoid valve module with several solenoid valves, e.g. during operation of a vehicle, can be prevented.

[0008] The solenoid valve module is in particular an assembly and / or a component which is intended to be mounted in one piece into a larger system, e.g. a vehicle. The term “intended” should be understood in particular to mean specially programmed, designed and / or equipped. The fact that an object is intended for a specific function should be understood in particular that the object fulfills and / or performs this specific function in at least one application and / or operating state. The solenoid valve module can comprise a single solenoid valve. Preferably, however, the solenoid valve module comprises a plurality of solenoid valves which are identical in construction or at least partially different from one another. The solenoid valves of the solenoid valve module can be assigned to a common system, such as a fluid line system, sensor cleaning system, cooling circuit, etc.Alternatively, different solenoid valves of the solenoid valve module could also be assigned to different systems. The solenoid valve module preferably forms at least part of a sensor cleaning system based on the dispensing of washer fluids for sensors, in particular driver assistance sensors, of vehicles, in particular self-driving vehicles. A solenoid valve of the solenoid valve module can thus be provided, for example, for controlling and / or regulating a fluid flow. For this purpose, the solenoid valve of the solenoid valve module can be designed so that the washer fluid can flow through it.

[0009] The module housing can have integrated fluid line channels. The module housing can form a manifold. However, the module housing can additionally or alternatively also enclose separate fluid line channels, such as hoses or the like. The module housing can form a module housing of a valve block with multiple solenoid valves. In this case, more than one coil former can be arranged at least partially or completely in the module housing. The module housing can be made of plastic, metal, or a different material. Preferably, the module housing is formed in one piece, preferably monolithic. Alternatively, however, the module housing can also consist of several parts that can be connected to one another. “Integral” is intended to mean, in particular, materially connected, for example, by a welding process and / or adhesive process, etc., and particularly advantageously be understood as molded, such as by production from a single cast and / or by production in a single or multi-component injection molding process. An inner wall of the module housing is preferably not visible from the outside in a finished / assembled state of the module housing, in particular of the solenoid valve module. The inner wall preferably faces an electromagnet of the solenoid valve / one of the solenoid valves mounted in the solenoid valve module. The electromagnet has the coil body. The coil body is preferably made of a plastic. The coil body can be designed as an injection-molded part. The coil body forms a receiving area for at least one magnetic coil winding wound with a circular or polygonal cross-section. The electromagnet has a magnetic core. The electromagnet has a magnetic armature.The solenoid armature can be moved linearly by controlling / energizing the solenoid coil winding. Depending on the position of the solenoid armature, flow through the respective solenoid valve is enabled, blocked, or throttled. The solenoid valve is preferably a seat valve with a valve seat that can be opened and closed by the solenoid armature.

[0010] According to the invention, the non-destructively irremovable, preferably mechanical, connection cannot be released non-destructively, i.e. cannot be released without destroying part of the connection (e.g. an adhesive or solder) or at least one of the connected parts. The non-destructively irremovable mechanical connection differs in particular from a press fit. The non-destructively irremovable mechanical connection is preferably a direct connection, which is produced without the need for further solid-state elements, such as screws or the like. A “direct mechanical connection” is to be understood in particular as a connection acting between two elements, such as the coil former and the module housing. A mechanical connection is preferably different from a magnetic connection and / or a purely frictional connection.Adhesive joints, soldered joints, or other joints in which only the auxiliary material, i.e., the adhesive or solder, etc., is destroyed upon removal, while the interconnected parts (e.g., coil former and module housing) remain undamaged, are also to be understood according to the invention as "non-destructively irreversible" joints. Alternatively, the non-destructively irreversible joints could also be simply joints, such as welded joints or fused joints, in which at least one of the interconnected components must be destroyed to separate the connection.

[0011] It is further proposed that the solenoid valve module have a valve functional element designed as a separate component different from the coil body, which is connected directly to an inner wall of the module housing in a non-destructive and permanent manner, preferably mechanically. This makes it possible to advantageously fix components of the solenoid valve module in a module housing of the solenoid valve module. Advantageously, a particularly simple and / or cost-effective fixation can be achieved. Furthermore, when fixing several solenoid valves in a common solenoid valve housing, simple and reliable tolerance compensation can advantageously be achieved. In particular, the valve functional element contributes to at least fulfilling at least one essential function of the solenoid valve. Preferably, the valve functional element fulfills at least one essential function of the solenoid valve.The essential function can include enabling controllable flow through the solenoid valve.

[0012] If the coil body and the valve functional element are non-destructively and permanently connected, preferably mechanically, to the same inner wall of the module housing, in particular to a different partial area of ​​the inner wall of the module housing, a high degree of compactness and / or simple and / or cost-effective manufacture can advantageously be achieved, in particular because the connection between the coil body and the valve functional element can be established with the same element, in particular the module housing. In particular, the valve functional element is connected to the module housing in the same way / using the same connection method as the coil body is connected to the module housing. Furthermore, it is proposed that the coil body and the valve functional element be non-destructively and permanently connected, preferably mechanically, to the inner wall of the module housing by a continuous connection area.This advantageously allows for a high degree of compactness and / or simple and / or cost-effective manufacturing. Advantageously, the connection of the coil body and the valve functional element to the module housing can be carried out in a single work step. In particular, the coil body is connected to a first partial area of ​​the inner wall of the module housing. In particular, the valve functional element is connected to a second partial area of ​​the inner wall of the module housing. In particular, the first partial area and the second partial area directly adjoin one another. In particular, the coil body and the valve functional element touch one another in the region of the connection area.

[0013] If, in addition, the coil body and the valve functional element are permanently connected to the inner wall of the module housing using the same, preferably mechanical, connection type, this can advantageously achieve particularly simple and / or cost-effective manufacturing. Advantageously, the connection of the coil body and the valve functional element to the module housing can be carried out in a single work step. The mechanical connection type is preferably a material connection, an adhesive connection, or, particularly preferably, a welded connection.

[0014] It is further proposed that the valve functional element forms a valve seat and / or a valve nozzle. This enables an advantageous, particularly compact, design. The valve seat forms, in particular, an end region of a flow channel of the valve functional element, in particular of the solenoid valve, which is provided for the selective sealing seating of the movable magnet armature. The valve nozzle forms, in particular, a fluid outlet for a fluid, in particular washing fluid, flowing through the solenoid valve depending on a position of the magnet armature, in particular depending on an opening or closing of the valve seat by the magnet armature. The valve nozzle can have a flow channel with a narrowing cross-section or a flow channel with an approximately constant cross-section.The valve functional element can be designed as a one-piece component comprising the valve seat, the flow channel, and / or the valve nozzle. The valve functional element can be designed as a monolithic injection-molded part.

[0015] Furthermore, it is proposed that the non-destructively permanent, preferably mechanical, connection be a material-to-material connection. This advantageously allows for a particularly strong, durable, and / or reliable connection. Advantageously, a minimum holding force can be set and / or achieved in a particularly simple manner. Furthermore, intrinsic fluid tightness can advantageously be achieved.

[0016] The non-destructively permanent, preferably mechanical, material-to-material connection can be designed in particular as an adhesive connection or as a soldered connection or the like. However, it is preferably proposed that the non-destructively permanent, preferably mechanical, connection is a welded connection. This advantageously makes it possible to achieve a particularly strong, permanent, and / or reliable connection. Advantageously, a minimum holding force can be set and / or achieved in a particularly simple manner. In addition, intrinsic liquid-tightness can advantageously be achieved. Furthermore, the connection can be easily produced. The welded connection can be produced by laser welding, friction welding, or particularly preferably by ultrasonic welding. All of these welding types allow welding inside the module housing.

[0017] It is additionally proposed that the non-destructively permanent, preferably mechanical, connection, in particular a welded connection, be fluid-tight, in particular liquid-tight and / or gas-tight. This advantageously allows a synergistic additional benefit to be achieved for fluid-conducting solenoid valves. Advantageously, simple production of a solenoid valve module suitable for fluid conduction can be achieved. In particular, the connection region at which the non-destructively permanent mechanical connection is created is arranged in a vicinity of a fluid connection / liquid connection, for example a fluid inlet / liquid inlet or a fluid outlet / liquid outlet of the solenoid valve module. In particular, the connection region at which the non-destructively permanent mechanical connection is created is arranged in an end region of the solenoid valve module which has the fluid connection / liquid connection.The end region extends in particular at most over 25%, preferably 15%, of a total extension of the solenoid valve module parallel to an outflow direction or inflow direction of the associated fluid connection / liquid connection.

[0018] If the coil body, in particular several coil bodies of the solenoid valve module that are formed separately from one another and arranged in the same module housing, are connected to the module housing independently of separate connecting elements, such as screws, hold-down plates, hold-down brackets, etc., cost savings and / or good tolerance compensation can advantageously be achieved if several correspondingly fixed coil bodies are present in a single module housing.

[0019] Furthermore, it is proposed that at least one surface region of the inner wall of the module housing, which has the non-destructively permanent, preferably mechanical, connection, extends at least at an angle, preferably at least substantially perpendicular, to a central axis of the coil body and / or to an intended direction of movement of a magnet armature of the solenoid valve module, preferably of the magnet armature associated with the electromagnet with the coil body. This advantageously allows for a particularly good force distribution / force effect of a fixing force generated by the non-destructively permanent mechanical connection to be achieved. The holding force advantageously acts parallel to a movement force of the magnet armature.In particular, this avoids a weakening of the non-destructively irreversible mechanical connection due to frequent armature movement, particularly in comparison to a parallel arrangement of the surface region of the inner wall containing the connection to the direction of movement of the armature. The term "essentially perpendicular" is intended here to define in particular an orientation of a direction relative to a reference direction, wherein the direction and the reference direction, particularly viewed in a projection plane, enclose an angle of 90° and the angle has a maximum deviation of in particular less than 8°, advantageously less than 5°, and particularly advantageously less than 2°. The central axis of the coil body preferably runs through a center of the armature, which is movably mounted in a central opening of the coil body.In particular, the surface area of ​​the inner wall having the non-destructively irremovable mechanical connection is arranged in a lower half, preferably quarter, of the solenoid valve housing facing the fluid outlet of the associated solenoid valve.

[0020] Furthermore, it is proposed that at least one surface region of the inner wall of the module housing, which has the non-destructively undetachable, preferably mechanical, connection, runs at least substantially parallel to an opening plane of a valve opening of the valve seat and / or to a nozzle opening of the valve nozzle. This advantageously makes it possible to achieve a high level of tightness, in particular liquid-tightness, of the solenoid valve module. By "substantially parallel" here, it is meant in particular an alignment of a direction relative to a reference direction, in particular in a plane, wherein the direction has a deviation from the reference direction of in particular less than 8°, advantageously less than 5°, and particularly advantageously less than 2°. The valve opening of the valve seat is formed in particular by a (first) end of the flow channel of the valve functional element.The nozzle opening of the valve nozzle is formed in particular by a (second) end of the valve functional element, in particular opposite the (first) end of the flow channel forming the valve opening of the valve seat.

[0021] It is further proposed that the solenoid valve module have at least one further coil body which, in an identical manner to the coil body, is directly and permanently mechanically connected to a further inner wall of the module housing, spaced from the inner wall, in a non-destructive manner. This advantageously makes it possible to obtain the solenoid valve module with multiple solenoid valves. Positioning of the multiple solenoid valves / coil bodies can be carried out by an auxiliary device which can be removed again after the solenoid valves / coil bodies have been fixed, since their function is now taken over by the non-destructively and permanently mechanical connection. This advantageously eliminates the need for a complex alignment geometry in the finished solenoid valve module. The coil bodies / solenoid valves of the solenoid valve module can, for example, be arranged in a row within the module housing.However, alternative arrangements are also conceivable.

[0022] Furthermore, a valve block with one or more solenoid valve modules forming a plurality of separately controllable seat valves is proposed. This advantageously allows for a high degree of compactness and / or modularity to be achieved. The solenoid valve modules combined to form the valve block can each have, or partially have, only a single solenoid valve / seat valve, or each have, or partially have, multiple solenoid valves / seat valves.

[0023] Furthermore, a method for producing the solenoid valve module is proposed, wherein, in at least one manufacturing step, the coil body is non-destructively and permanently connected, preferably mechanically, to an inner wall of the module housing, in particular welded, preferably ultrasonically welded. This allows advantageous fixation of components of the solenoid valve module in a module housing of the solenoid valve module. Advantageously, a particularly simple and / or cost-effective fixation can be achieved. Advantageously, hold-down devices and the like can be dispensed with. Advantageously, assembly can be simplified and / or accelerated.

[0024] The solenoid valve module according to the invention, the valve block according to the invention, and the method according to the invention are not intended to be limited to the application and embodiment described above. In particular, the solenoid valve module according to the invention, the valve block according to the invention, and the method according to the invention may have a number of individual elements, components, and units that differs from the number stated herein to fulfill a function described herein.
