Description

Title of the invention: Fastening assembly technical field

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

[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 [Fig. 2], a known prior art fastening assembly comprises: - a bodywork element of a vehicle, comprising a sheet metal part having an opening; the sheet metal having a constant thickness; - a clip, including elastic interlocking means arranged to fix the clip in the hole in 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 located within the given range of values.

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

[0005] One possible solution to circumvent this problem is to provide a dedicated support piece to fix the clip to the bodywork element. This solution entails significant additional costs (design, materials, management, assembly, etc.). 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 a fastening assembly comprising: - a bodywork element of a vehicle, comprising a sheet metal part having an opening; the sheet metal having a constant thickness; - a clip, including elastic interlocking means arranged to fix the clip in the hole in 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; remarkable in that: - the constant thickness of the sheet metal has a value located outside the range of given values; - the sheet metal has stamped areas arranged to deform the interface so that the interface has a thickness with a value within the given range of values.

[0007] Thus, such a fastening assembly according to the invention allows, thanks to the stamped areas, the thickness of the interface to be adjusted so as to guarantee the interface thickness, that is to say, that the interface has a thickness with a value within a given range of values. The given range of values ​​is predetermined so as 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 value of the constant thickness of the sheet metal with respect to the range of given values.

[0009] The fastening assembly according to the invention may include one or more of the following characteristics.

[0010] According to one feature of the invention, the elastic interlocking means comprise elastically deformable elements, arranged to penetrate into the orifice of the sheet metal.

[0011] According to a feature of the invention: - the constant thickness of the sheet metal has a value located below the range of given values; - the embossed areas are arranged to deform the interface so that: the interface has raised patterns and hollow patterns, and the elastically deformable elements rest on the raised patterns when the clip is fixed in the hole in the sheet metal.

[0012] Thus, one advantage provided is to guarantee the interface thickness for thin sheets. The protruding patterns form bearing surfaces for the elastically deformable elements.

[0013] According to a feature of the invention: - the constant thickness of the sheet metal has a value located beyond the range of given values; - The embossed areas are arranged to deform the interface so that: the interface has raised and recessed patterns, and The elastically deformable elements rest on the hollow patterns when the staple is fixed in the hole in the sheet metal.

[0014] Thus, one advantage provided is to guarantee the interface thickness for thick sheets. The hollow patterns form bearing surfaces for the elastically deformable elements.

[0015] 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 come to rest against the sheet metal.

[0016] Thus, one advantage provided is excellent stability of the clip on the sheet metal. The range of values ​​given is predetermined so as to ensure satisfactory tensioning of the clip between the lugs and the tabs.

[0017] 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 box.

[0018] According to a 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.

[0019] 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.

[0020] The invention also relates to a vehicle, comprising a fastening assembly according to the invention.

[0021] 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
