[0103] FIG. 1 shows the snap-in mounting 1 according to the invention in a first embodiment, wherein a major part of the snap-in mounting was cut out for illustrating the inner setup of the receiving part 3, wherein a part of the top cover 100 is also shown, with the bottom side of the top cover 100 facing upwards, which is the opposite direction of the normal mounting position, where the bottom side faces downwards.

[0104] The snap-in mounting 1 serves for mounting the top cover 100 onto the engine of a motor vehicle. The snap-in mounting 1 consists of the female part 50. The female part 50 consists of the holding part 2 and the receiving part 3. The holding part 2 is adapted to be fixed to the top cover's 100 bottom side, which faces the engine of a motor vehicle when mounted, and the holding part also serves for holding the receiving part 3. The receiving part 3 is adapted to receive the ball-shaped end of a male part 60 by a snap-in connection. The receiving part is formed by a thermoplast, here e.g. polyamide, using injection moulding.

[0105] The holding part 2 has a first support wall 4 and a second support wall 5, facing the first support wall 4. Both support walls are plain plates, which are arranged in a distance, thereby limiting the insert volume of the holding device 2 for inserting the receiving device 3 through an opening 9, best seen in FIG. 6, of the holding device by a lateral movement, which is parallel to the second support wall 5. Said distance substantially corresponds to the height of the receiving part 3.

[0106] The first support wall 4 and a second support wall 5 are plain plates, carried by a carrier construction, to which the support walls 4, 5 are integrally connected. The second support wall has an opening, which technically is used as a part of the restriction device, explained below, and which also serves for allowing to let the ball-shaped end of the male part passing through the housing and to engage the ball-receiving portion of the receiving part for establishing the coupling position by snap-in, and for the male part to be removed for releasing the coupling position of the female part and the male part.

[0107] As shown in FIGS. 2b and 2c, the first support wall 4 has a first portion 4a and a second portion 4b. The second portion 4b of the first support wall 4 is parallel to the second support wall 5, thereby defining a virtual support plane P, along which the receiving part and the holding part can be slidably moved in relation to each other. Also the base part 8 is parallel to the second support wall 5. The first portion 4a of the first support wall 4 is tilted by the angle a=15 with respect to the second portion 4b of the first support wall 4. Thereby, the opening 9 of the insert volume of the holding part is enlarged and a sliding ramp is defined by first portion 4a, which facilitates inserting the receiving part into the insert volume of the holding part 2. The carrier construction consists of a vertical side wall 6, a leg portion 7 and a base portion 8. The side wall 6 runs substantially parallel to the central axis A of the snap-in mounting, shown in FIG. 1, and provides housing for the receiving device 3 in combination with the second support wall 5. In the position where the receiving part 3 is properly inserted into the insert volume of the snap-in mounting, and the latter is mounted to the bottom side of the top cover of the engine of a motor vehicle, referred to as the mounting position, the housing is encompassing the receiving device 3 and is open only in one lateral direction for providing the insert opening 9, thereby providing a high mechanical stability.

[0108] The holding part 3 has a sliding portion, which is adapted to allow for a relative displacement of the receiving part 3 and the holding part 2 by a sliding motion. The sliding portion comprises the first support wall 4 and the second support wall 5, which define the insert volume, into which the receiving part 3 is inserted, while still being capable to be laterally moved, at least under the relatively high forces of positioning, when the male part enters the funnel-shaped receiving portion of the receiving part 3, which thereby is caused to slide and to align, i.e. self-center, the male part with the ball-receiving portion.

[0109] The snap-in mounting comprises a clamping device for clamping the receiving part within the holding part. The clamping device, preferably, is adapted to counteract the sliding movement of the receiving part relative to the holding part by friction, such that the receiving part may be still be laterally moved by sliding but may be fixed by friction during the normal mounting position, when the top cover is mounted on top of the engine of the motor vehicle and normally operated. The clamping device is realized here by the plain first support wall 4, which is arranged tilted with respect to the plain second support wall 5 by an angle a, here being 15. The height of the receiving part, the average distance between the first support wall 4 and the second support wall 5 and the angle a are configured such that a proper clamping effect is achieved. This configuration is facilitated by choosing a thermoplast, here polyamide, for the polymer material of the receiving part, and also for the holding part, which are each formed one-piece by injection moulding.

[0110] The holding part 2 has a restriction device to restrict the sliding movement of the receiving part 3 relative to the holding part 2 to a predetermined range of a sliding area, in particular by blocking the sliding movement by means of at least one restriction portion 10. The restriction portion 10, see FIG. 1, is an opening having a circular cross section and being provided in the second support wall 5. The restriction portion 10 restricts the sliding displacement of the receiving part 3 relative to the holding part 2 along a support plane parallel to the second support wall 5. Furthermore, the restriction portion 10 acts as a forcible control for guiding the also circular-shaped engagement projection 48, see FIG. 2c, of the receiving part 3, which is an integral part of the receiving part 3 and which engages the opening 10 of the holding part 2, when the receiving part 3 is inserted into the insert volume of the holding part 2. The displacement being limited by the restriction device serves to provide a tolerance for centring the receiving part 3, in particular the ball receiving portion, with respect to the ball-shaped end of the male part 60, when the top cover 100 is mounted onto the engine of a motor vehicle. In a similar function, the restriction device also comprises the second opening 11 being provided in the first support wall 4, which is engaged by the circular-shaped engagement projection 49 of the receiving part 3. The maximum displacement of the receiving part 3 by a sliding movement within the holding part 2, which is allowed by the receiving part 3, can be dimensioned to be 3 mm, e.g. 1.5 mm laterally in each positive or negative x and y direction of a Cartesian coordinate system, in the position where the receiving part is inserted into the holding part and centred.

[0111] The female part 50 forms a mounting system according to the invention, if in combination with a male part having a ball-shaped end, which is adapted to fit into the substantially ball-shaped inner volume of the ball-receiving portion of the receiving part 3.

[0112] Referring to FIG. 1, the receiving part 3 has one ball-receiving portion 31 and one funnel-shaped portion 32.

[0113] Referring to FIG. 4, the receiving part 3 has four click walls 33, which are arranged and shaped thin enough to be displaced by being elastically bended under the force provided by inserting the ball-shaped end of the male part 60 into the ball-receiving portion 31, such that the click walls support and retain the male part at the receiving part by engaging the undercut provided at the ball-shaped end of the male part, whereby the click walls 33 are also adapted for allowing a smooth release of the ball-shaped end of the male part from the ball-receiving portion, when the female part and the male part are decoupled.

[0114] The funnel-shaped receiving portion 32 includes a funnel-shaped inner volume, and the ball receiving portion 31 includes a ball-receiving inner volume, which is substantially ball-shaped.

[0115] The receiving part 3 has eight rib portions and the ball-receiving inner volume is defined by the surface of the eight rib portions 34, 35, which are facing the ball-receiving inner volume.

[0116] The funnel-shaped inner volume is defined by the surface of the click walls 33, which are at one end integrally connected to a substantially vertical and cylindrical side wall 36 of the receiving part, and at the other end continuously leading into the four rib portions 34, which form the lower part of the ball-shaped receiving portion and the ball-shaped inner volume, respectively.

[0117] The ball-receiving portion has an opening 37, through which the ball-shaped end of the male part 60 is inserted into the ball-receiving portion for providing coupling of the female part 50 and the male part 60. The rib portions 34, 35 are aligned at least in part around the ball-shaped inner volume in a longitudinal direction, considering the ball-shaped inner volume having a south pole, which lies in the center of the opening, and an opposing north pole, which are connected by a central linear axis running through both poles and by lines of longitude leading around the ball-shaped inner volume.

[0118] The ball-receiving inner surface of the ball-receiving portion 31 is defined by a first set of four rib portions 35, which defines a first half of the ball-shaped inner volume, and by a second set of four rib portions 34, which defines a major part of the second halfalso referred to as lower halfof the ball-shaped inner volume, considering the receiving part being divided by a virtual plane P, see dashed line P in FIG. 4, running through the centre of the ball-shaped inner volume.

[0119] The rib portions 35 of the first set of rib portions and the rib portions 34 of the second set of rib portions are respectively provided with a number N=4, and are arranged with an offset by a rotation to each other around the central axis, wherein the rotational shift preferably corresponds to an angle b=180/N=45. The distance between the longitudinal rib portions 35, 34 of the first and second set of rib portions is chosen such that the vertical projections of all rib portions onto plane P do not cross each other. This allows to mould the first set of rib portions in a first mould form and to mould the second set of rib portions in a second mould form, without creating undercut portions at the receiving part. Moreover, an optimum of mechanical stability is achieved, while providing a particular light-weight and cost saving construction. Moulding a part without undercut portions is advantageously, because, in general, undercuts may be moulded, but require a side action or side pull. This part has to be used additionally to the two mould forms for being moved separately from the two halves of mould forms, thereby increasing the cost of the moulded part due to an added cost of the mould itself and added complexity of the injection moulding machine.

[0120] The rib portions 35 of the first set of rib portions are formed to be lamellae which extend longitudinally in the direction from the equator of the spherical inner volume towards the north pole, while they are arranged self-supporting. This way, the rip portions 35 behave flexible like a spring, which contributes to dampen noise, which is associated with vibrations, which are transferred to bend the lamellae 35. Each lamella 35 is supported by a rib element at another substantially vertical side wall 39 of the receiving part 3.

[0121] FIG. 3 shows a perspective view of an embodiment of a top cover 100 according to the invention in a first embodiment, which is provided with four snap-in mountings of FIG. 1, wherein the bottom side of the top cover is shown facing upwards. The top cover 100 according to the invention for covering the engine of a motor vehicle has a top side and a bottom side, wherein multiple snap-in mountings 1 according to the invention are connected with the bottom side 101 of the top cover 100, for mounting the top cover onto the engine of a motor vehicle, see FIG. 3. The FIG. 3 indicates that the height of the leg portion 7 of the holding part 2 may be used to compensate for local differences in the distance between the male parts, provided at the engine, and the corresponding mounting side at the bottom side of the top cover 100, in the mounting position of the top cover.

[0122] FIG. 7a shows a perspective view of an embodiment of a top cover 110 according to the invention in a second embodiment, which is provided with three snap-in mountings of FIG. 1 and one snap-in mounting 1, which is not self-centring, wherein the bottom side of the top cover is shown facing upwards. The snap-in mounting 1, which is not self-centring, has a holding part and a receiving part, which are integrally formed with each other, and which are therefore not including a sliding portion, a clamping device and a restriction device.

[0123] The top cover 110 is provided with at least one snap-in mounting 1 according to the invention, which is fixed by US welding to the bottom side of the top cover. Three snap-in mountings 1 according to the invention are fixed at different positions to the bottom side 111 of the top cover 110. This allows the top cover to be mounted in a stable position on the engine of a motor vehicle.

[0124] Three snap-in mountings 1 are fixed at different positions to the bottom side 111 of the top cover, wherein exactly one snap-in mounting 1 is provided, which does not have the self-centring feature, which means that the receiving part cannot be slidably moved at the holding part of the snap-in mounting by the ball-shaped end of the male part during coupling of the female part and the male part. The snap-in mounting 1, which does not have the self-centring feature, serves as the first mounting point, where the top cover 110 is first mounted to the male part 60 at the engine, where it remains rotatable around the central axis A of the mounting point, wherein the three snap-in mountings 1 according to claim 1, having the self-centring feature, will be mounted subsequently to the residual male parts 60 at the engine, wherein possible positioning errors of the female parts of the snap-in connection according to the invention or possible positioning errors of the male parts, the errors being within the considered tolerances, will be compensated by the self-centring feature.

[0125] FIG. 7c shows, in a perspective view similar to FIG. 7b, a further snap-in mounting 1 according to the invention, which is not self-centring, because the holding part 2 and the receiving part 3 are formed integrally. The receiving portion of the receiving part 3 is formed in analogy to the receiving portion of receiving part 3. The receiving portion of receiving part 3 is integrally connected to the holding part 2 via one connecting wall.

[0126] FIG. 8a shows a perspective view of a mounting system 300 having a snap-in mounting 200 according to the invention in a second embodiment, and also shows a male part 60 having a ball-shaped end, which is coupled to the receiving part 203.

[0127] Generally, for an embodiment as shown in FIGS. 8a and 8b, the holding part 202 of the snap-in mounting (200) has an opening (206) and defines an insert volume for inserting and receiving at least a part of the receiving part (203), and the receiving part has an insert portion (203a), which may be formed as a circular-ring disc element (203a) or a circular disc element, which is dimensioned to fit into the insert volume and to remain movable within the insert volume by a sliding movement, wherein the receiving part has a receiving portion (203b), which is integrally connected to the insert portion and which at least partly protrudes through the opening (206).

[0128] In FIG. 8a, the holding part 202 has a support wall 204, see FIG. 8b, and a base portion 205, which is integrally connected with the support wall 204 by at least one connection element 207, which is a narrow side wall. The support wall 204, the connection element 207 and the base portion 206 are arranged such that theyin combination with a bottom side 101, 111 of the top coverdefine the insert volume of the holding part 2, because the holding part and in particular the support wall are configured such that the support wall is held in a distance to the bottom side of the top cover in the mounting position. The insert volume is adapted to receive at least in part the receiving part 203 by inserting the receiving part 203 at least partly into the insert volume of the holding part 202, in particular before fixing the snap-in mounting to the bottom side of the top cover. Also for this embodiment, a restriction device, here comprising opening 206, for restricting the movement and/or a clamping device for counteracting said movement in any direction in the plane parallel to the support wall is provided. The receiving part 203 has an insert portion 203a, which is formed as a circular-ring disc element, which is dimensioned to fit into the insert volume and to remain movable within the insert volume by a sliding movement. The receiving portion 203b, which is configured for receiving the ball-shaped end of the male part, may protrude from the opening 206 provided in the support wall 204. The base part 205 is a circular-ring shaped disc element, and the support wall 204 also is a circular-ring shaped disc element. The support wall has the opening 206, which also acts as a through-hole for letting the receiving part protrude from the insert volume. Such an embodiment also provides the feature of self-centring, which is advantageously for compensating positioning errors occurring during production and fixing of the snap-in mounting to the bottom side of the top cover. Said alternative embodiment is particularly low-cost in the production and light-weight. The receiving portion 203b includes a number N of rib portions, here a number N=4 of self-supporting click walls 233, which allow reliably coupling and uncoupling the female part 250 and the male part 60.

[0129] The combination of the snap-in mounting (here: 200) according to the invention and the male part 60 is a mounting system according to the invention.

[0130] The top covers 100 and 110 according to the invention both are configured to have self-dampening properties, such that sound absorption is achieved in combination with the snap-in mountings according to the invention, which are formed from a polymer material containing a thermoplast.

[0131] FIGS. 9a and 9b shows, in a perspective view similar to FIGS. 8a and 8e, a further mounting system 300 having another snap-in mounting 200 according to the invention, which is not self-centring, because the holding part 202 and the receiving part 203 are formed integrally. The receiving portion of the receiving part 203 is formed in analogy to the receiving portion of receiving part 203.

[0132] FIG. 10 shows a diagram with the method steps of an embodiment of the method according to the invention for producing a snap-in mounting according to the invention. The method 400 of producing the snap-in mounting according to claim 1, provides at least the steps of: [0133] forming the receiving part as an integral mould part by injection moulding (401), and [0134] providing the holding part (402), in particular by injection moulding the holding part as an integral mould part; [0135] preferably: assembling the receiving part and the holding part by inserting the receiving part into the holding part (403).

[0136] According to sub step (401a), an injection moulding device is used for moulding the receiving part, which comprises a first mould form and a second mould form, which can be closed to define the negative contour of the receiving part, the receiving part, the first mould form and a second mould form being respectively configured such that the receiving part does not require an undercut portion.
