Definitions
- the present invention relates to a housing for a control device and in particular to a seal of a housing of a brake control device by means of a wet seal.
- control units are reliably protected against external environmental influences, while at the same time they can be exposed to considerable temperature fluctuations.
- the control units are previously bolted or riveted, with sealing elements made of rubber or plastic are used to achieve a reliable seal between the components of the housing.
- the present invention solves at least some of the above-mentioned problems by a housing according to claim 1, a brake control device according to claim 7 and a utility vehicle according to claim 8.
- the dependent claims 2 to 6 relate to advantageous developments of the subject matter of claim 1.
- the present invention relates to a housing for a control unit.
- Housing includes a lid, a bottom plate and an elastic adhesive bond.
- the elastic adhesive bond forms a wet seal between the lid and the bottom plate.
- the wet seal may in particular be waterproof or airtight.
- the lid comprises a rigid material and the bottom plate forms at least partially a membrane to compensate for a pressure difference between an environment and an interior of the housing by bending or deformation of the bottom plate.
- the lid includes a groove with a
- Adhesive and the bottom plate a projection, wherein the projection of the bottom plate protrudes into the adhesive to form the elastic bond between the lid and the bottom plate.
- the projection comprises retaining means around a
- the retaining means comprise at least one of the following: a further projection, at least one opening, a roughened surface area, barbs, an irregular surface structure.
- the elastic adhesive bond is fully formed.
- the present invention also relates to a brake control apparatus having a
- control unit can in principle be any control unit of any vehicle, in particular a
- FIG. 1 shows a housing for a control device according to an embodiment of the present invention.
- Fig. 2 shows further details of the housing according to further embodiments of the present invention.
- Fig. 1 shows a housing according to an embodiment of the present invention, which is suitable for a control device in a vehicle, in particular in a commercial vehicle.
- the housing includes a lid 110, a bottom plate 120, and an adhesive bond 130 (e.g., adhesive) to allow a tight connection between the lid 110 and bottom plate 120.
- the cover 1 10 and the bottom plate 120 may in particular be connected to each other air and waterproof.
- Control unit may be any control unit, in particular a brake control unit should be included.
- the bottom plate 120 in this embodiment comprises a groove 1 15, in which an end portion of the lid 1 10 is used to form the elastic adhesive bond 130.
- Fig. 2 shows further details of the housing according to further embodiments.
- the elastic adhesive bond 130 is again formed within a groove 1 15, wherein the groove is now part of the lid 1 10.
- the bottom plate 120 includes a projection 125 which extends into the groove 1 15 and is enclosed by the elastic adhesive bond 130 so far that thereby a waterproof possible connection is achieved.
- the elastic adhesive bond 130 includes a resilient adhesive that ensures sufficient flexibility to maintain a permanently reliable bond even when repeated heat loads cause the lid 110 and bottom plate 120 to move relative to each other, which is common in commercial vehicles the case is (for example, due to different thermal expansion coefficients).
- the projection 125 includes holding means 127, which are formed, for example, at one end of the projection 125 and cause a better grip of the bottom plate 120.
- the holding means 127 can be formed of various types. Thus, for example, holes, hooking, further projections are suitable for preventing withdrawal of the bottom plate 120 from the elastic adhesive connection 130.
- the invention is not limited to this specific form. Rather, any irregular shape of the projection 125 may constitute such holding means 127 as long as it is capable of improving the holding of the bottom plate 120 in the elastic adhesive joint 130.
- the bottom plate comprises at least a portion which is formed as a membrane 121, in order to achieve a pressure equalization between an environment of the housing and a housing interior by bending or deformation of the membrane portion 121.
- the bottom plate 120 may be at least partially thinner or have a corresponding shape, which facilitates bending of the bottom plate 120.
- the bottom plate 120 may, for example, comprise a metal, which may be formed at least in sections as a sheet, in order to be able to compensate for the mentioned pressure differences.
- the bottom panel 120 may include bumps 122 (i.e., it is not necessarily planarized) which, on the one hand, provide support for members within the housing, but may also facilitate flexing of the membranous portion 121.
- conventional housings include separate pressure equalization elements. These pressure compensation elements allow a gradual pressure equalization, which can occur during assembly, for example.
- the pressure compensation elements are additional components that make the structure of the controllers more complicated and can also form an additional source of error. But they also make it difficult to manufacture the control units.
- the present invention also relates, in particular, to housings which do not have such separate pressure compensation elements.
- An advantage of embodiments is the ease of assembly. In particular, no rivets or screws are required, which allows space-saving installation.
- the groove 1 15 can according to the geometry of the bottom plate 120th be adapted (eg in terms of breadth, depth, a full education, etc.).
- embodiments achieve a reliable tightness between the lid 1 10 and the bottom plate 120, without tight tolerances would be considered.
- close tolerance dimensions are to be observed in conventional screw or rivet connections in order to ensure, for example, a reliable seat of the separate seal.
- Another advantage of embodiments is that the housing does not require a pressure compensation element, since the elasticity, for example, the bottom plate 120, a pressure equalization (eg due to the temperature variation) allows.
- the present invention also relates to a brake control device having one of the previously described housings.
- the present invention is also useful for other control devices within the vehicle (e.g., an engine control unit).
- both the bottom plate 120 and the cover 1 10 is plasma treated prior to bonding, or a plasma cleaning, in order to ensure reliable grip and tightness.
