[0002] Modular housing system

[0003] The present invention relates to a modular, waterproof housing system for accommodating electronic components for the operation of electrical devices under harsh and humid environmental conditions.

[0004] Circuits that can be integrated into such housings are particularly suitable for use in environments where the system is not constantly accessible or in wet, adverse conditions, such as during the operation of unmanned marine surface vehicles. These vehicles have a multitude of sensors and measuring systems, the electronics of which each require complex, waterproof installation and connection. Furthermore, the mechanical stresses acting on the components and electrical connections in the form of rapid changes in impulse or shocks from wind, waves, or collisions pose a problem. While waterproof housings for electronics with interfaces for connecting cables do exist, they are not modular and cannot be readily used for such operation.The setup and connection of the entire measurement system used has so far been a complex and costly individual solution for each of these vehicles, requiring electrically trained specialists for modifications, for example when replacing measuring devices.

[0005] Therefore, the object of the invention is to propose a housing system with which all necessary electronic components of external devices used on such vehicles, in particular measuring instruments and probes, can be assembled and integrated in a modular, simple, waterproof, and robust manner, thus enabling the easy replacement and integration of external devices, as well as electronic components, or the simple addition of further devices.

[0006] This problem is solved according to the invention by a housing system according to claim 1.

[0007] According to the invention, a housing system comprising at least two openable, enclosed housings for receiving electronic components is provided. The term "housing" is not defined by a specific shape, but simply refers to a watertight sealed space. The housing system according to the invention is advantageously modular, allowing any number of housings to be combined depending on the electronic components required. These housings are identical in the properties described below, but do not necessarily have to be identical in their geometry, particularly their length.

[0008] The housings according to the invention each have a first connection side with a coupling arranged thereon, wherein the coupling has at least one sealed connector, and a second connection side with at least one further connector arranged thereon, wherein a watertight electrical connection can be established between each of the two housings by means of a mechanical connection of the coupling of one housing with the second connection side of the other housing, which can be established by means of mechanical connecting means, and by plugging the connectors of one housing and the further connectors of the other housing into each other, wherein the transmission of a current signal and a data signal is made possible via the electrical connection.

[0009] In a manufacturing step of the housings according to the invention, the housing is connected at the first connection side, in particular by a mechanical connection, to the coupling to be connected in a watertight manner. VKK Patent Attorneys PartG mbß Our sign: 7038. Thus, a housing according to the invention has one coupling and at least one free connector. In the assembled housing system, a free connector of one housing is thus connected to a coupling of another housing, so that each connection between two housings has exactly one coupling.

[0010] The use of housings protects the electronic components and their connections from splashing water, external weather conditions, and similar influences. When the housings are unplugged (i.e., with one connection side open), they already have an IP53 protection rating; after the connectors are plugged in, they achieve an IP68 protection rating. This enables low-maintenance, long-term operation of the installed electronic components and connections, as well as the connected electrical devices that require them, even under adverse external conditions.

[0011] The matching connectors of the two connection sides of the housings to be connected, or between the free side of the coupling of one housing and the second connection side of the other housing to be connected, enable a simple combination and connection of several housings and thus a high degree of modularity.

[0012] Furthermore, no external cables are required for the electrical and logical connection of the components of two housings. All necessary cables, such as power supply and data lines, are integrated into the connectors and routed between the housings, making a connection simple, robust, and interchangeable. The use of the coupling also provides enhanced protection for the connection between the two housings, particularly against contact with water. VKK Patent Attorneys PartG mbß Our reference: 7038

[0013] At the last housing of an enclosure system, where there is no connection to another housing on one side, a blanking cap is provided to protect the contacts from water ingress if they are not plugged in. In particular, a power cable connection or a connection to a power supply is also provided at another free end of the enclosure system, as well as a data line for transmitting data from the electronic components and connected electrical devices, especially to and from a central control unit.

[0014] In this embodiment of the invention, each housing is equipped with a microcontroller. This microcontroller is configured to control the electronic components installed within the respective housing and to communicate with other microcontrollers in all other housings of the housing system. This enables the formation of a network. Furthermore, the housing system can initially operate autonomously, i.e., without direct intervention or switching by a user, and can react automatically to changes. Simultaneously, remote control is enabled by transmitting data to a central control unit. By forwarding data from the central control unit to a remote receiving device, all components of the system can be switched and controlled remotely. This allows, among other things, for the protection of the system in the event of unforeseen changes in environmental conditions (temperature, humidity, etc.).) to change the settings of the installed electronic components and electrical devices, or to compensate for component failures or malfunctions. In this way, a reliable, long-lasting VKK Patent Attorneys PartG mbß our reference: 7038.

[0015] The use of the housing system and the electrical devices connected and operated by it is made possible.

[0016] Furthermore, the system incorporates control software that generates a digital copy of the enclosure system. This copy is accessible via a user interface, enabling continuous and easy remote monitoring and control of the system.

[0017] In an embodiment of the invention, it is provided that the first connecting side and the second connecting side are offset by 180° and / or wherein the housing is made of powder-coated aluminum or of PA12GB30.

[0018] A 180-degree offset of the two connection sides enables a classic block connection of the interconnected housings within the enclosure system. A lateral arrangement is also possible, resulting in an angled connection between the interconnected housings. This also allows for branching in the form of a connecting branch, expanding the enclosure system's application possibilities to more complex circuits.

[0019] The use of aluminum as the housing material offers the advantage of high hardness and durability at a low weight. PA12GB30 housings are easy to manufacture, further reducing weight and offering high heat and chemical resistance.

[0020] Furthermore, in a further development of the invention, it is provided that the coupling has a rubber-metal connection, in particular wherein the coupling has a first and a second metal plate, consisting in particular of 5083 aluminium or steel type A4 or A5, between which a plastic vulcanization is located, in particular an EPDM70 plastic vulcanization.

[0021] In this way, a connection between housings can be implemented not only in a watertight and modular manner, but also with exceptional flexibility and adaptability. The outer metal plates enable a simple and secure connection to the housings and stabilize the plastic connection from the outside. The plastic damping material located between the metal plates is bonded firmly and watertight to the metal plates, primarily through vulcanization. A particular advantage of this damping is that it absorbs external movements, vibrations, and shocks to the system, thus protecting the actual electrical connections between the housings. Furthermore, these external forces are also absorbed by the seals between the coupling and the respective metal plates, resulting in a particularly tight and durable connection.

[0022] To manufacture a coupling according to the invention, it is particularly advisable to produce the plastic-metal connections of the coupling using adhesive methods. Compression molding, injection molding, or injection compression molding processes are applicable for this purpose, after the metal plates of the coupling, which are to be firmly bonded to the plastic damping material, have been arranged in a mold. In this way, a bond is created with the plastic material to be vulcanized, in particular EPDM70.

[0023] These processes are common and proven in the production of a rubber-metal bond by means of vulcanization.

[0024] In an embodiment of the invention, it is also provided that the first and second metal plates have a border with a sealing ring and / or an applied EPDM seal on their respective outer sides facing the housing connecting to VKK Patentanwälte PartG mbß our sign: 7038.

[0025] In this way, a connection between metal plates and the first and second connecting sides of housings, which can be created via any mechanical connecting means, is designed to be waterproof.

[0026] According to a particularly advantageous embodiment of the invention, the side of the first metal plate of the coupling facing the first connection side of the housing to be connected has threaded openings, so that the first metal plate can be screwed to the first connection side of the housing. To ensure watertightness, the first metal plate has a sealing ring arranged around the openings. Alternatively, the use of an EPDM seal applied to the first metal plate is provided.

[0027] Furthermore, it is provided that mechanical connecting means are provided for connecting the second metal plate of the coupling of one housing to the second connecting side of the further housing to be connected, in particular designed as cotter pins, buckles or screws.

[0028] In this way, several housings can be easily connected to form a housing system. In particular, threaded openings can be provided in the second metal plate for this purpose.

[0029] It is also provided that the housings of a fully developed housing system according to the invention have an openable and closable cover on their upper side, through which the interior of the housing is accessible. VKK Patent Attorneys PartG mbß our reference: 7038

[0030] A major advantage is that the enclosures are easily accessible from the outside for installing, replacing, or performing maintenance on components.

[0031] It is further provided in an embodiment of the invention that the housing has an externally visible screen on which status information of the housing and contained electronic components can be displayed.

[0032] This allows the condition of the housing components to be viewed from the outside without requiring an opening. Furthermore, it is possible to display physical parameters such as humidity or temperature if appropriate measuring devices are installed inside the housing.

[0033] The invention also provides that the interior of a housing comprises a humidity sensor and / or a desiccant, in particular silica gel, and / or a water cooling system, which is in particular installed in a housing base.

[0034] This makes it possible to identify, particularly during extended use of the system, when a housing requires maintenance due to the ingress of small amounts of water or a leak occurring over its service life. The use of cooling in the housing base allows for the use of devices that generate more heat without the housings becoming excessively hot.

[0035] Furthermore, it is planned that the housings will have interchangeable panels that allow access to the inside of the housing.

[0036] This additional access point is particularly advantageous for routing cables. Specifically, the plates are arranged laterally, between the first and second connection sides, such that a main part of the housing can be manufactured in one piece, without interruptions or joints. This is achieved by increasing the surface area on portions of the housing's side surfaces. The plates are advantageously easy to replace or retrofit. In particular, the plates are screwed to the housing. A sealing surface, especially in the form of a sealing ring, is provided on the back of each plate facing the housing.

[0037] In an advantageous further development of the invention, it is also provided that the plates have a waterproof cable connection, in particular in the form of connectors or a cable gland.

[0038] The cable connection allows for the connection of external devices. The panels thus enable the easy addition and switching of external devices from the outside, while simultaneously connecting them to electronics installed inside the housing. The panels are modularly configurable and can have a smooth surface if no additional cable connection is required. They can also be equipped with connectors or cable glands. A particularly advantageous feature of the panels is their resealability and replaceability. Should a cable connection be damaged or need to be replaced, simply removing the panel and replacing the connection or inserting a different panel is sufficient. The rest of the housing remains unaffected by this replacement. With integrally manufactured housings, this can sometimes eliminate the need to replace the entire housing.The removal of the entire switching and electronics system allows for easier maintenance and a longer service life. Furthermore, connections of external devices are better protected against shocks and vibrations during operation, as the plate (VKK Patentanwälte PartG, our reference: 7038) has a damping effect and, compared to a surface of the overall housing, is excited to lower vibration amplitudes when external forces occur.

[0039] The invention is described in a preferred embodiment by way of example with reference to a drawing, further advantageous details of which can be seen in the figures of the drawing.

[0040] Functionally identical parts are marked with the same reference symbols.

[0049] Figure 5: another embodiment of a coupling.

[0050] Figure 1 shows a possible embodiment of a housing 1 of a housing system according to the invention. This housing 1 is provided on a first connecting side A for connection to a coupling 12 (not shown) with pins 20 as a mechanical connecting element 6. Corresponding openings 22 are arranged on a first and second connecting side A, B of the housing 1. In the operating state of the housing system according to the invention, electronic components 7 for operating external devices 8 (not shown) connected to the housing 1 are installed in the housing 1. According to the invention, it is also possible to install a device to be operated, such as a measuring probe, within a housing 1. To allow easy access to the interior 11 of the housing, the housing 1 has a screw-on, openable cover 10 on its upper surface 9.In this way, the installed electronic components 7 are easily accessible for maintenance and assembly purposes without affecting the overall structure. On the first connection side A, the housing 1 has connectors 2 for power supply and for data input and output of the connected electronic components 7. In a preferred embodiment, the housing 1, when ready for use, has a microcontroller 8 (not visible here) that controls the installed electronic components 7. A screen 15 is also arranged on the top 9 of the housing 1, which displays the status of the installed electronic components 7, such as on / off or error messages. Furthermore, with the installation of appropriate measuring instruments, physical states such as humidity or temperature can be displayed via this screen 15. In particular, this screen is designed as a resistive touchscreen and is coupled to the microcontroller 8 of the housing 1.On the side surfaces 23 of the housing 1, a surface of the housing is advantageously enlarged in a stepped manner in the illustrated embodiment. Several plates 16 are located here, which are screwed to the housing 1. A watertight connection between the plate 16 and the housing 1 is ensured by sealing surfaces formed on the back of the plates 16, in particular in the form of inserted sealing rings. The interior of the housing 11 is accessible via the plates 16 insofar as external devices 18 can be connected to it. (VKK Patentanwälte PartG, our reference: 7038.)

[0051] The electronic components 7 contained within the housing 11 can be accessed at this location. This applies at least if the plate 16, as shown, is designed with a cable connection 17. However, the invention also encompasses plates 16 without a cable connection 17, i.e., with a smooth surface. Due to the integrated cable connection 17 in the plate 16, replacing it during repair, maintenance, or modification of the assembly does not require opening or replacing the entire corresponding side of the housing 1. The housing surface remains untouched except for the comparatively small surface area of ​​the plate 16. In particular, cable connections 17 can thus be replaced individually without affecting any other cable connections 17. In the illustrated embodiment, the cable connection 17 on each plate 16 is provided as a cable gland.Integrating connectors as cable connections 17 is also possible, but this is significantly more complex and expensive. The embodiment shown, with cable connections integrated into plates 16, offers the additional advantage of reduced vibrations of the surfaces supporting the connections. This reduces the force exerted on the connections and increases their durability. The plates 16 are arranged at an angle on the housing 1, such that their surface normals each form an acute angle with the surface normal of a top surface 9 of the housing 1. This provides further protection for the installed connections.

[0052] Figure 2 shows a top view of a housing system according to the invention. In the embodiment shown, the housing system comprises three interconnected housings 1, 1'. According to the invention, the housings 1, 1' are connected watertight via couplings 12. According to the invention, the integration of further housings 1 is possible with minimal effort using additional couplings 12. Each coupling 12 is connected to a first housing 1. [VKK Patentanwälte PartG mbß unser Zeichen: 7038]

[0053] The connecting side A of a housing 1 is connected to the housing 1 via a mechanical connection. The coupling 12, according to the illustrated embodiment, has a first metal plate 13A and a second metal plate 13B. A plastic damper 20 is arranged between these. In the illustrated embodiment, the coupling 12 and the housing 1 are connected via pins 21, four of which are arranged on each side of the first and second metal plates 13A and 13B facing away from the plastic damper 20. The housing 1 connected to the coupling 12 has corresponding openings 22. According to a further advantageous embodiment of the invention, the openings 22 of the housing are provided with threads into which the coupling can be screwed. In this way, further such housings 1' can be connected to the arrangement shown, thus enabling the modular production of a housing system according to the invention.The connection via the coupling 12 and the mechanical connecting elements 6, which in the illustrated embodiment are designed as pins 21, is initially a mechanical connection. This connection is watertight; the external seal is achieved via sealing rings at the transitions between the first and second metal plates 13A, 13B of the coupling 12 and the first and second connection sides A and B of the two connected housings 1, 1'. The coupling 12 itself is also watertight; for this purpose, a bond was created between a rubber layer of the plastic damping 20 and the first and second metal plates 13A, 13B of the coupling 12 by means of vulcanization. In this way, two housings 1 can be connected simply and watertight according to the invention. In addition, the connection by means of the flexible coupling 12 is able to absorb vibrations or shocks and dissipate them from within the housings 1, 1' or 1'.to keep away from the connections and cable connections contained in the coupling. A connection of power signal 4 and data signal 5 in housing 1 in the operating state VKK Patentanwälte PartG mbß our reference: 7038 installed, not shown, electronic components 7 takes place via plug connections, which are made by plugging together connectors 2 (not shown) and further connectors 3 of the connected housings 1, 1'.

[0054] Figure 3 shows a circuit diagram of an embodiment of the housing system according to Figure 2. Electronic components 7 installed within the housings 1, 1' connected by the couplings 12 are shown. These components can be, for example, voltage converters, computers, or measuring instruments. In principle, the invention provides for the integration of all electronic components 7 and their circuits and connections necessary for the operation of electrical devices connected to the housings 1, 1', which are to be operated, for example, on an unmanned, maritime surface vehicle, within the housing system. This protects the electronic components 7 and circuits from environmental influences. The aforementioned electrical devices can be either external devices 18 connected to the side plates 16 of the housings 1 via cable connections 17 or devices installed within the respective housing 1.Within the housings, microcontrollers 8 are also sketched, which independently control and switch the electronic components 7 installed in the housing 1. They exhibit, among other things, the following characteristics:

[0055] Humidity sensors, current and voltage measuring devices. Furthermore, the microcontrollers 8 connected to one another in the housing system according to the invention form a network, for which, in the embodiment shown, they are connected to a central control unit 9 via data signals 5 routed through the housings 1. The respective microcontrollers 8 identify the corresponding segment consisting of housing 1 and the installed electronic components 7. For the sake of simplicity, the circuits and wiring of the individual elements contained in the housings 1 are not shown; moreover, they vary depending on the application. Essential to the invention is the transmission of the current signal 4 and the data signal 5 through the couplings 12 between the housings 1, 1'. Only these enable the modular use of the housings 1, 1'.The housing system can be powered during operation via connectors on a second connection side B of the housing 1, or alternatively via a cable connection 4' on one of the plates 16. At the opposite end of the housing system, where no further housing 1 ' is connected, the plug contacts 2 of the housing 1 are protected by a blanking cap 14.

[0056] Figure 4a shows an embodiment of a coupling 12 of a housing system according to the invention. This coupling has a first metal plate 13A and a second metal plate 13B. In the housing system constructed according to the invention, the first metal plate 13A of the coupling 12 is connected to the first connecting side A of the housing 1. A connection to a further housing 1 can be made by connecting the second metal plate 13B of the coupling 12 to the second connecting side B of the further housing 1' using mechanical connecting means 6. In the illustrated embodiment, these are designed as pins 21, which are to be inserted into corresponding openings 22 of the further housing 1'. A plastic damper 20 is arranged between the first and second metal plates 13A, 13B. This damper is flexible, i.e., expandable and compressible, and thus able to compensate for forces occurring between the housings 1, 1' connected by the coupling 12 shown.In the embodiment shown, the second metal plate 13B is closed except for connector 2. These are connected to further connector 3 on the second connection side B of the VKK Patentanwälte PartG mbß our reference: 7038 when the coupling 12 is connected to a further housing 1'.

[0057] Housing 1' is connected. This ensures a data and power connection between housings 1, 1' via coupling 12.

[0058] Figure 4b shows a side view of the embodiment of the coupling 12 shown in Figure 4a. The sequence of metal and rubber is visible in the form of the first and second metal plates 13A, 13B and the plastic damping 20. In a preferred embodiment of the coupling 12 according to the invention, the tight and watertight connection between the metal and rubber is achieved by vulcanization, in particular by compression molding, degassing, or injection molding. EPDM70 is preferably used as the material for the plastic damping 20 due to its tightness, weather resistance, and resistance to UV radiation and ozone. The metal plates 13A provide the coupling 12 with the stability and rigidity necessary for the mechanical connection with the housing 1.Also shown are connectors 2,3 arranged on the sides of the first and second metal plates 13A, 13B in the operating state of the coupling 12 in the direction of the housings 1 , 1' to be connected, with the help of which a power and data connection between the housings 1 , 1 ' is made possible.

[0059] Fig. 5 shows a further embodiment of a coupling 12 according to the invention. In this embodiment, the first and second metal plates 13A, 13B do not have any mechanical connecting means for connecting to a first and second connection side A, B of the housings 1, 1' to be coupled. The coupling is achieved solely via additional connectors 3 designed as bulkhead connectors, which are connected to the connector clamps 2 on the first and second connection sides A, B of the housings 1 and 1', respectively. Thus, mechanical and electrical coupling is achieved solely via the plug connection. To seal the connection, the outer surfaces of the first and second metal plates are [VKK Patentanwälte PartG mbß unser Zeichen: 7038]

[0060] Seals 24 in the form of sealing rings are arranged 13A and 13B. This embodiment has the advantage that couplings 12 only need to be plugged in and no further mechanical connection is required. This simplifies both the assembly of the housing system according to the invention and the manufacture of the housings 1 themselves.
