Description

technical field

[0001] The invention relates to the technical field of fastening assemblies comprising a clip fixed in an opening in a sheet metal of a vehicle body element.

[0002] The invention finds its application in particular in the fixing of a battery powering a telecommunications box. State of the art

[0003] As illustrated in the figure 2 A known prior art fastening system comprises: a bodywork element of a vehicle, comprising a sheet metal having an opening; the sheet metal having a constant thickness; a clip, comprising elastic interlocking means arranged to fix the clip in the opening of the sheet metal, the clip being intended to receive a battery; the sheet metal having an interface, in contact with the clip when the clip is fixed in the hole in the sheet metal, the interface being intended to have a thickness with a value within a given range of values; the constant thickness of the sheet metal having a value within the given range of values.

[0004] Such a set of prior art fixing is not entirely satisfactory insofar as the "vehicle" architects have to find a place in the body element where the constant thickness of the sheet metal has a value within the given range of values, which is not always an easy thing, especially when the given range of values ​​is restricted (e.g. [1.35 mm; 1.55 mm]).

[0005] One possible solution to circumvent this problem is to provide a dedicated support piece to attach the clip to the body panel. This solution entails significant additional costs (design, materials, management, assembly, etc.). Document DE10214048A1 shows a fastening assembly comprising a vehicle body panel, including a sheet metal part with a hole; the sheet metal having a constant thickness; a clip, including means arranged for securing the clip in the hole in the sheet metal, the clip being intended to receive a battery. Document EP0722880A2 shows elastic interlocking means arranged for securing a clip in a hole in a sheet metal part. Description of the invention

[0006] The invention aims to remedy, in whole or in part, the aforementioned drawbacks. To this end, the invention relates to fastening assemblies with the characteristics of claims 1 and 2.

[0007] Thus, such a fastening assembly according to the invention allows, thanks to the stamped areas, for the thickness of the interface to be adjusted in order to guarantee the interface thickness, that is to say, that the interface has a thickness within a given range of values. The given range of values ​​is predetermined in order to ensure satisfactory stability of the clip on the sheet metal.

[0008] Such a fixing assembly makes it possible to do without a dedicated support piece, and to free oneself from the constraint of the constant thickness value of the sheet metal with respect to the given range of values.

[0009] One advantage provided is the ability to guarantee the interface thickness for thin sheets. The raised patterns form bearing surfaces for elastically deformable elements.

[0010] One advantage provided is the ability to guarantee the interface thickness for thick sheets. The hollow patterns form bearing surfaces for elastically deformable elements.

[0011] According to one feature of the invention, the elastic interlocking means comprise: elastically deformable lugs, arranged to penetrate the opening in the sheet metal; elastically deformable tabs, arranged to rest against the sheet metal.

[0012] One advantage provided is excellent stability of the staple on the sheet metal. The range of values ​​given is predetermined to ensure satisfactory tensioning of the staple between the lugs and the tabs.

[0013] According to one feature of the invention, the fastening assembly includes a battery mounted on the clip, the battery preferably being a battery to power a telecommunications unit.

[0014] According to one feature of the invention, the constant thickness of the sheet metal has a value greater than or equal to 0.65 mm and less than or equal to 2.8 mm.

[0015] According to one feature of the invention, the given range of values ​​exhibits: a lower limit equal to 1.35 mm, and an upper limit equal to 3 mm.

[0016] The invention also relates to a vehicle, comprising a fastening assembly according to the invention.

[0017] According to one feature of the invention, the vehicle includes a quarter window; and the bodywork element is arranged under the quarter window. Brief description of the drawings

[0018] Other features and advantages will become apparent in the detailed description of different embodiments of the invention, the description being accompanied by examples and references to the accompanying drawings. Figure 1is a schematic perspective view, illustrating a clip intended to secure a battery. Figure 2 is a schematic top view, illustrating a state-of-the-art fixing assembly. Figure 3 is a schematic top view, illustrating a fastening assembly according to the invention for a thin sheet metal. Figure 4 is a schematic top view, illustrating a fastening assembly according to the invention for a thick sheet metal.

[0019] It should be noted that the drawings described above are schematic, and are not necessarily to scale for the sake of readability and to simplify their understanding. Detailed description of the implementation methods

[0020] Identical elements or elements performing the same function will bear the same references for the different embodiments, for the sake of simplification. Fastening assembly

[0021] One object of the invention is a fastening assembly, comprising: a bodywork element of a vehicle, comprising a sheet metal 1 having an opening; the sheet metal 1 having a constant thickness: a clip 2 (clearly visible at the figure 1 ), including elastic interlocking means arranged to fix the clip 2 in the hole in the sheet 1, the clip 2 being intended to receive a battery (not illustrated); the sheet 1 having an interface, in contact with the clip 2 when the clip 2 is fixed in the orifice of the sheet 1, the interface being intended to have a thickness with a value within a given range of values; remarkable in that: the constant thickness of the sheet 1 has a value outside the given range of values; the sheet 1 has stamped areas 10 arranged to deform the interface so that the interface has a thickness with a value within the given range of values.
