Description

Technical Field

[0001] The present invention relates to a sealing device, in particular to a sealing device for isolating a first fluid chamber from a second fluid chamber or a plurality of fluid chambers. The sealing device comprises a sealing element arranged between a first object and a second object. Background Art

[0002] So-called bearing seals or metal-elastomer seals are known from the prior art and are used for isolating between two components or objects.

[0003] The bearing seals or metal-elastomer seals known from the prior art usually have, in particular, a metallic base body and an elastic sealing body arranged on the base body. With the aid of such bearing seals or metal-elastomer seals, two objects can be connected to one another in a sealed manner in the region of a flat connection surface, wherein preferably the introduction of grooves into the components for fixing the sealing element can be avoided. Tolerance problems when introducing the grooves thus do not arise. In comparison with liquid seals, which are often selected when the components to be connected have flat connection surfaces, bearing seals or metal-elastomer seals can also be disassembled again relatively easily.

[0004] Furthermore, objects to be connected to one another, in particular metallic objects to be connected to one another, can be connected via the metallic base of the support seal or metal-elastomer seal. Thus, an improved electromagnetic compatibility (EMC) can be provided by means of the support seal or metal-elastomer seal. Therefore, support seals or metal-elastomer seals are also becoming increasingly popular.

[0005] The sealing body of the support seal or metal-elastomer seal is usually injection-molded onto an especially annular, preferably metallic base body in an injection molding process. The size of the injection mold to be used, especially the size of the required injection molding machine, is mainly determined by the size or dimensions of the base body.

[0006] Therefore, it has not been possible to produce support seals or metal-elastomer seals for battery boxes of electric vehicles so far, because they cannot be produced in known injection molds and / or injection molding machines due to their size and / or dimensions. Summary of the invention

[0007] The object of the present invention is therefore to provide a sealing device which, on the one hand, can be produced simply and cost-effectively and which, in addition, enables a reliable separation between a first fluid chamber and a second fluid chamber.

[0008] This object is achieved by a sealing device having the features of technical solution 1.

[0016] Since the sealing element components can be connected to each other, wherein the base part forms the base and wherein the sealing body part forms the sealing body, it is preferably possible to achieve that the elastic sealing body part can be correspondingly injection-molded onto the base part in an injection molding process based on the smaller size or dimensions of the individual sealing element components. The individual sealing element components can then be connected to form a sealing element. It is therefore possible in particular to produce the elastic sealing body part in a relatively small injection mold and / or a relatively small injection molding machine.

[0029] In the context of this description and the present application, a direct connection is understood in particular to mean that the base parts are directly connected to one another, ie in particular no elastic sealing body part is required for connecting the base parts.

[0050] Preferably, only two connecting sections are respectively constructed to be complementary to each other, i.e., the two connecting sections comprise mutually complementary connecting section geometries with a punch and a die complementary to the punch. In particular, different connecting section geometries are provided. This can avoid incorrect connection of the base part and / or the sealing element components to each other.

[0051] This preferably makes it possible to provide a sealing element which is easy to produce and in particular easy to mount.

[0052] In one embodiment of the invention, it is provided that the elastic sealing body parts each comprise a connecting section for connecting the elastic sealing body parts which abut against each other or overlap each other.

[0057] Preferably, the base part can be connected to the elastic sealing body part arranged thereon by means of the connecting section in a direction perpendicular to the main extension plane, without the connection of the base part being hindered by undercut structures of the connecting geometry.

[0058] The connecting geometry is designed, for example, as a chamfer or a bevel, ie as a surface arranged obliquely to the main extension surface.

[0125] Figure 1 A sealing device, generally designated 100 , is shown.

[0126] The sealing device 100 is used in particular to seal a first fluid chamber 102 from a second fluid chamber 104 , for example in a battery compartment or a control compartment 106 of a motor vehicle 108 , in particular an electric vehicle.

[0127] The sealing device 100 includes a sealing element 110 for being arranged between a first object 112 , such as a cover of a battery box or a control box 106 , and a second object 114 , such as a body portion of the battery box or the control box 106 .

[0128] The sealing element 110 comprises a preferably dimensionally stable main body 116 and an elastic sealing body 118 arranged on the main body 116 .

[0129] The sealing element 110 is therefore in particular a so-called seat seal and / or a so-called metal-elastomer seal.

[0130] The sealing element 110 comprises a total of four through-holes 120 on the base body 116 , through which connecting elements, in particular screws, for connecting the first object 112 to the second object 114 can be respectively inserted and passed.

[0131] The sealing element 110 includes two Figure 1 The sealing element components 122 are shown already connected to each other.

[0132] The sealing element components 122 each include a base component 124 and an elastic sealing body component 126 arranged on the base component 124 .

[0133] The base part 124 of the sealing element component 122 forms the base body 116 and thus provides a load-bearing function for the sealing element 110 .

[0134] The elastic sealing body part 126 of the sealing element component 122 forms the elastic sealing body 118 and thus provides the sealing function of the sealing element 110 .

[0135] In particular, base parts 124 of base body 116 each include two connecting sections 128 for connecting base parts 124 to one another.

[0136] The base member 124 may be arranged along a direction perpendicular to the sealing element 110. Figure 4 The directions of the main extension surfaces 130 shown in FIG. 1 , in particular along an assembly direction 132 , are connected to one another, in particular plugged into one another.

[0137] The elastic sealing body 118 and / or the elastic sealing body part 126 preferably include an elastomeric material 133 or are formed by an elastomeric material 133. The elastomeric material 133 includes or is in particular ethylene acrylate rubber (AEM). Alternatively or in addition to this, the elastomeric material 133 is ethylene propylene diene monomer rubber (EPDM), acrylate rubber (ACM), fluororubber (FKM), hydrogenated acrylonitrile butadiene rubber (HNBR) or silicone rubber (MVQ), in particular vinyl methyl silicone rubber (Vinyl-Methyl-Polysiloxan).

[0138] Main body 116 and / or main body part 124 are produced in particular from or include a metallic main body material 135. Metallic main body material 135 is in particular steel or aluminum.

[0139] As an alternative or in addition thereto, it is conceivable for base body 116 and / or base body part 124 to be produced from a plastic material or to include a plastic material.

[0140] Preferably, base body 116 and / or base part 124 are produced completely by punching and / or laser cutting from a metallic base material 135 , for example a sheet metal material, so that in particular no further process steps are required for producing base body 116 and / or base part 124 .

[0141] In this case, connecting section 128 of base part 124 is preferably also produced by punching and / or laser cutting.

[0142] The elastic sealing body parts 126 of the elastic sealing body 118 are preferably each injection-molded onto the base part 124 using an injection molding process. When the elastic sealing body parts 126 are injection-molded onto the base part 124, the elastic sealing body parts 126 are in particular not connected to one another.

[0143] In the injection molding process, in particular only a separate elastic sealing body part 126 is injection molded onto the base part 124 and thus forms the sealing element component 122 .

[0144] exist Figures 1 to 8 In the sealing element 110 shown in FIG. 8 , the sealing element components 122 are already connected to one another by means of a connecting section 128 .

[0145] The main body 116 of the sealing element 110 is preferably designed in an annular shape, in particular in an annular closed shape.

[0146] Since base body 116 and / or base part 124 are produced in particular from an at least substantially inflexible or hard material, preferably from a metallic base material 135 , base body 116 can in particular provide a load-bearing function for sealing element 110 .

[0147] As from Figure 1 and 4 It can be clearly seen from FIGS. 8 to 8 that sealing element 110 and / or base body 116 are preferably designed to be flat.

[0148] The sealing element 110 and / or the base body 116 extend in particular at least approximately along a main extension surface 130 (see Figure 4 ).

[0149] In order to produce the annular closed shape of the main body 116 shown in the figures, the sealing element components 122 can be connected to one another in a jigsaw-like manner, in particular in a form-fitting manner.

[0150] In particular, a jigsaw-like connection of the sealing element component 122 is achieved via the connecting section 128 of the base part 124 .

[0151] The sealing element components 122 , which are in particular releasably connectable to one another, may preferably be connected to one another indirectly or directly, in particular at a joining region 134 of the base part 124 .

[0152] In the exemplary embodiment of sealing element 110 shown in the figures, base parts 124 are connected to one another indirectly via elastic sealing body parts 126 arranged on base part 124 .

[0153] For this purpose, the elastic sealing body part 126 is preferably not injection-molded only onto the circumferential inner edge 136 of the main body 116 .

[0154] Furthermore, elastic sealing body part 126 is also injection-molded onto edge 138 of main body 116 or main body part 124 in the region of connecting section 128 .

[0155] However, it is also conceivable that the base body parts 124 are directly connected to one another in the joining region 134 and that the elastic sealing body part 126 is therefore arranged only on the inner edge 136 of the annularly closed base body 116 .

[0156] As can be clearly seen in the figure, base parts 124 can be connected to one another by means of connecting sections 128 , preferably in a jigsaw-like manner, in particular in a form-fitting manner.

[0157] In particular, connecting sections 128 are designed to be complementary, so that when base parts 124 are connected to one another along assembly direction 132 , connecting sections 128 and / or elastic sealing body parts 126 arranged therein engage with one another in a form-fitting manner.

[0158] In order to connect the base parts 124 to one another, the connecting sections 128 have in particular two undercut sections 140 in each case.

[0159] As in Figure 3As can be clearly seen in FIG. 1 , the connecting section 128 is preferably designed symmetrically with respect to the plane of symmetry 142 .

[0160] In particular, undercut section 140 is arranged and designed such that base parts 124 connected to one another are coupled, in particular connected in a form-fitting manner, in the region of connecting section 128 in a direction parallel to main extension surface 130 of sealing element 110 .

[0161] For this purpose, the undercut section 140 is undercut along a direction extending parallel to the symmetry plane 142 .

[0162] The base parts 124 connected to one another are therefore fixed in the region of the connecting section 128 in a direction parallel to the main extension surface 130 of the sealing element 110 , in particular in a form-fitting manner.

[0163] The connecting sections 128 preferably each include a connecting section geometry 144 .

[0164] The two connecting sections 128 are in particular designed to be complementary to one another, so that each connecting section 128 comprises a positive mold 145 of the connecting section geometry 144, wherein each connecting section 128 comprises a negative mold 147 of the connecting section geometry 144 (see Figure 2 ).

[0165] In the exemplary embodiment of the sealing element 110 shown in the figures, the connecting section geometry 144 is designed in particular in the manner of a jigsaw puzzle.

[0166] As an alternative to this, it is conceivable that the connecting section geometry 144 , ie the punch 145 and / or the die 147 , has, in particular, a dovetail geometry.

[0167] In order to be able to simplify the assembly of the sealing element 110 , it is provided in particular that only two connecting sections 128 in each case correspond to one another, that is to say that only two connecting sections 128 in each case comprise a connecting section geometry 144 that is complementary to one another.

[0168] In particular, only one connecting section geometry 144, namely a mutually complementary punch 145 and a die 147 of the connecting section 128, is provided for the sealing element component 122 to be connected and / or the base part 124 to be connected. Therefore, the sealing element component 122 and / or the base part 124 can be connected to each other in particular without errors.

[0169] As can be clearly seen in the drawings, the elastic sealing body part 126 is preferably interrupted in the joining area 134 and forms a seam 149 there (see Figure 2 ).

[0170] The elastic sealing body parts 126 therefore extend in particular in each case along an edge 138 of the respective base part 124 .

[0171] As described above, in the exemplary embodiment of sealing element 110 shown in the figures, elastic sealing body part 126 extends along inner edge 136 and along edge 138 of connecting section 128 of base part 124 .

[0172] In particular, the elastic sealing body part extends here in the region of the connecting section 128 of the connecting section geometry 144 .

[0173] In the exemplary embodiment shown in the figures of sealing element 110 , elastic sealing body part 126 is arranged both on punch 145 and on die 147 of connecting section geometry 144 of connecting section 128 , i.e., elastic sealing body part 126 is arranged on punch 145 and on die 147 , respectively.

[0174] As an alternative to this, it is conceivable to arrange the elastic sealing body part 126 only on the punch 145 or the die 147 of the connecting section geometry 144 of the connecting section 128 .

[0175] If an elastic sealing body part 126 is arranged in each case on both base parts 124 in the joining region 134 of the base parts 124 , the elastic sealing body parts 126 in particular each comprise a connecting section 146 for connecting the elastic sealing body parts 126 which are in contact with or overlap each other.

[0176] Especially in Figure 5 Neutral Figures 6 to 8 Such a connecting section 146 can be clearly seen in the alternative detailed view of FIG.

[0177] The connecting section 146 is particularly designed so that when the sealing element component 122 and / or the base part 124 are connected to each other, in particular when the sealing element 110 is arranged between the first object 112 and the second object 114, the elastic sealing body parts 126 are sealed against each other in the area of ​​the connecting section 146.

[0178] The coupling sections 146 each have a coupling geometry 148 .

[0179] As in Figures 6 to 8 It can be clearly seen in FIG. 1 that two elastic sealing body parts 126 each have a connecting geometry 148 which is complementary to one another.

[0180] In particular, the coupling geometry 148 of the coupling section 146 has no undercuts along the assembly direction 132 of the sealing element component 122 and / or the base part 124 .

[0181] Preferably, the elastic sealing body parts 126 can bear against one another in a sealing manner during assembly or connection of the base part 124 in a direction perpendicular or oblique to, ie transverse to, the main extension plane 130 of the sealing element 110 .

[0182] In particular, base part 124 can be connected to elastic sealing body part 126 arranged thereon by means of connecting section 128 along assembly direction 132 , without the connection of base part 124 being impeded by undercuts of connecting geometry 148 .

[0183] In the sealing element 110 Figures 1 to 6 In the exemplary embodiment shown in FIG. 1 , the connecting geometry 148 is designed, for example, as a chamfer 150 or a bevel 152. The chamfer 150 or the bevel 152 is arranged in particular at an angle β in the range of about 40° to about 70° relative to the main extension surface 130 of the sealing element 110.

[0184] In the vicinity of the sealing element 110 Figure 7 and 8 In the embodiment shown in FIG. 1 , the coupling geometry 148 is designed in a stepped manner and has a step 154 ​​(see Figure 7 ) or two or more steps 154 (see Figure 8 ) However, it is also conceivable that the connecting geometry 148 is designed to be corrugated.

[0185] If an elastic sealing body part 126 is provided in each joining region 134 only on one base part 124 , preferably no connecting geometry 148 is required.

[0186] As in Figure 5 It can be clearly seen in FIG. 1 that the elastic sealing body 118 has a sealing body height 156 in a direction perpendicular to the main extension plane 130 of the sealing element 110 .

[0187] The base body 116 has a base body height 158 ​​along a direction perpendicular to the main extension plane 130 of the sealing element 110 .

[0188] The sealing body height 156 is preferably greater than the base body height 158 ​​, in particular by about 15% to about 40%, preferably by about 25%.

[0189] The base height 158 ​​of the base 116 is preferably in the range of about 1 to about 3 mm, and in particular in the range of about 1.5 to about 2 mm.

[0190] In particular, it is thereby possible for the elastic sealing body 118 to be compressed at least in regions when the sealing element 110 is arranged between two objects 112 , 114 .

[0191] In the region of the sealing lip 160 arranged at the inner edge 136 of the base body 116 , the elastic sealing body 118 has a sealing body height 156 which is greater than the sealing body height 156 in the region of the connecting section 128 and / or the coupling section 146 (see Figure 5 ).

[0192] exist Figure 1 and 3 It can be clearly seen in FIG. 1 that the sealing element components 122 are constructed to be almost identical.

[0193] In the exemplary embodiment shown in the figures, the sealing element 110 comprises two identical base parts 124 .

[0194] The elastic sealing body parts 126 of the sealing element 110 are virtually identical, but are designed differently in the joining region 134 , in particular in the region of the connecting section 146 .

[0195] Each base part 124 is assigned a respective elastic sealing body part 126 , so that the number of elastic sealing body parts 126 corresponds in particular to the number of base parts 124 .

[0196] In summary, the present invention provides a sealing device 100 having a sealing element 110 that can be produced simply and cost-effectively and that enables simple and reliable sealing between a first fluid chamber and a second fluid chamber.
