Description

 mounting assembly

The present invention relates to a fastening arrangement of a component on a further component, according to the preamble of claim 1. The invention also relates to a motor vehicle having such a fastening arrangement.

Due to the higher technical requirements, in particular with regard to pressure and temperature in cycles with carbon dioxide (CO ₂ ) as a refrigerant, the CO ₂ components have a comparatively high component weight in comparison to, for example, R 134a components. Due to this higher weight and also the higher thermal and pressure-related loads, such components must be kept reliable on the one hand, but on the other hand, also cost in a motor vehicle.

JP 2004218989 A discloses a generic fastening arrangement of a cylindrical component on a further component, wherein the cylindrical component has two grooves oriented orthogonally to the cylinder axis and partially buried in a lateral surface.

From DE 200 05 887 U1, a further fastening arrangement in the manner of a bracket holder for a refrigerant tank of a vehicle air conditioning system, in particular an accumulator, is known, which has a bracket mounting holes and at least one with a closure clamped around the refrigerant tank strap. The bracket has a quick release with integrated form-fitting elements for clamping and holding. This is a mounting technology simple, but also a high level of reliability ensuring holding the refrigerant tank to be achieved. From DE 297 19 733 U1 a fastening arrangement with a holder for a dryer or accumulator container of a vehicle air conditioning system is known.

Generally, however, known from the prior art holding devices or mounting arrangements have a relatively high installation costs and are therefore expensive.

The present invention therefore deals with the problem of providing an improved or at least one alternative embodiment for a fastening arrangement of the generic type, which is in particular less expensive and easier to assemble.

This problem is solved according to the invention by the subject matter of independent claim 1. Advantageous embodiments are the subject of the dependent claims.

The present invention is based on the general idea, the attachment of a particular cylindrical component, for example. A rechargeable battery of a mobile air conditioner on another component, eg. On a body of a motor vehicle, mainly by positive (positive, positive or positive and non-positive) To realize connectors that are not only inexpensive to produce, but also are quick and easy and therefore inexpensive to install. The fastening arrangement according to the invention in this case comprises the component to be fastened, which has two orthogonal aligned to the axis, partially buried in a lateral surface and parallel grooves. In this case, the fastening arrangement serves for fastening the aforementioned component to a further component, for example a body of a motor vehicle, wherein this body or the further component is not part of the fastening arrangement. According to the invention now at least two holding elements are provided, each having a web and a complementary having the associated groove on the component formed spring and a head portion, wherein the head portion are arranged on one side and the spring on the opposite side of the web. Such holding elements can be realized relatively easily and inexpensively by means of cut extruded profiles. Furthermore, according to the invention, at least one retaining ring is provided, in which the component is at least partially positively, positively or positively and non-positively received in the installed state and the two opposite radially outwardly directed, preferably opposite, recesses and a tab for attachment to the other component. An inner diameter of the retaining ring is matched with the exception of the radially outwardly directed recesses to an outer diameter of the component, whereby the positive, non-positive or positive and non-positive reception of the component can be effected in the retaining ring. In the installed state, the at least two holding elements now engage with their springs in a form-fitting manner in the component-side grooves, while they are also arranged in the holding ring with their webs in the associated recesses, for example. With their respective head section, the retaining elements are supported on an upper edge of the associated recess on the retaining ring. To produce the fastening device according to the invention thus only the two holding elements must be inserted with their springs in the associated grooves on the component and then the component together with the two holding elements arranged in the associated retaining ring in such a way that the holding elements engage with their webs in the associated recesses , An insertion of the component in the retaining ring takes place from above and that far until the two holding elements rest with their respective head portion, which protrudes orthogonal to the web, on the upper edge of the associated recess. An inserted in the retaining ring member is thus fixed at least positively and reliably therein and can now be fixed on the tab of the retaining ring on the other component, eg. A motor vehicle body. Of course, a first-time fixation of the retaining ring to the other Component, eg. On the body of the motor vehicle, and only then subsequent insertion of the component in the retaining ring conceivable. Since the retaining ring can be produced purely theoretically as a low-cost extruded profile, which only has to be cut to length, can be achieved with the mounting arrangement according to the invention, on the one hand reliable and on the other hand easy to mount attachment.

In an advantageous development of the solution according to the invention, at least one retaining element has a web section adjoining the head section and extending parallel to the web, which web forms a groove together with the web of the retaining element. As a result, encompassing the edge of the recess in the retaining ring is achieved when the component is inserted, whereby a particularly reliable fixation of the component in the retaining ring can be achieved.

In a further advantageous embodiment of the solution according to the invention, the web / web section has / has a chamfer at its end facing away from the head section. Such a chamfer allows a simplified insertion of the component with the retaining elements arranged therein in the associated retaining ring. If, for example, the retaining element not only has the web, but also a web section, then the two bevels are aligned with the groove arranged therebetween. This also makes the assembly can be simplified and achieved.

In a further advantageous embodiment of the solution according to the invention, at least one holding element has a tab for attachment in the further component, in which case a further retaining ring is provided in addition to the aforementioned retaining ring, in which the component in the installed state form-fit, non-positive or form-fitting. and is positively received and has the two opposite, radially outwardly directed recesses, but no tab for attachment to the other component. The necessary Liehe tab is now arranged according to the invention on the holding element. Purely theoretically, it is thus conceivable that the fastening arrangement comprises only a single retaining ring with a tab arranged integrally thereon or two such retaining rings, or such a retaining ring and an additional further retaining ring, however, has no such tab, so that in this case Holding element with an integrally disposed thereon or formed thereon tab is used. Already this non-exhaustive enumeration gives an idea of the wide range of possibilities for securing the component via the fastening arrangement according to the invention to the further component, for example to a body of a motor vehicle.

In a further advantageous embodiment of the solution according to the invention / is a holding element and / or at least one retaining ring as an extruded profile, in particular as an aluminum extruded profile formed. The production of such extruded profiles is on the one hand a cost-effective and on the other hand high-quality manufacturing process, wherein the holding elements or the retaining rings need only be cut to length in terms of their length. In addition, aluminum extruded profiles have a low weight and high strength and are particularly suitable for motor vehicle construction.

It is expedient to provide at least one vibration-damping decoupling element with an outer annular groove, which passes through an associated lug on the retaining ring or on the retaining element and wherein an edge of an associated through-opening in the lug engages in the annular groove. In particular, a vibration transmission between the further component and the component, for example a motor vehicle body and an accumulator of an air conditioning system, can be minimized via such a vibration-damping decoupling element. At least two decoupling elements with different damping properties and / or different sizes are expediently provided. in the Motor vehicle act on the component to be held via the fastening arrangement according to the invention different forces, for example, the forces to be absorbed by the holding device in the vertical direction are greater than those in the horizontal direction. For this reason, for example, need-based and load-corresponding decoupling elements may be provided, so that, for example, a larger decoupling element is provided for receiving vertical forces.

The present invention is further based on the general idea to use such a mounting arrangement in a motor vehicle and for securing a battery of a mobile air conditioner to a body. As a result, the assembly of the battery to the body can be significantly simplified and accelerated at the same time.

In a further advantageous embodiment of the solution according to the invention a threaded bolt is arranged on the body, which penetrates the passage opening of the respective decoupling element. In addition, a suitable for the respective decoupling element collar sleeve is provided, which is arranged in the assembled state in the through hole of the decoupling element between the threaded bolt and the decoupling element. By means of a nut, which pretensions the respective decoupling element via the collar sleeve against the body in the state turned up on the threaded bolt, the component can be fixed relative to the body. The collar sleeve itself usually has an at least slightly shorter axial length than the associated decoupling element, whereby the collar sleeve when tightening the nut on the pin compresses the decoupling element and thus biases against the body. The collar sleeve has a hollow cylindrical shaft, which is followed by the end-side radial collar. The hollow cylindrical shaft delimits the threaded bolt with its inner lateral surface in the assembled state, whereas with its outer lateral surface it is defined in the passage opening. tion of the decoupling element is arranged. The outer radius of the shaft of the collar sleeve corresponds to the inner radius of the passage opening of the decoupling element.
