Definitions
- the present invention relates to a front foot structure of a motor vehicle, aiming to limit rotation around a vertical axis of this front foot, and more particularly to a structure comprising a front foot lining on which an upright lining is secured. bay, a dashboard cross member, a door strip and a connecting element between the dashboard cross member and the front leg.
- Such a structure limits the rotation, around a vertical axis, of the front foot in the event of a frontal impact. This rotation is due to the substantially longitudinal thrust of the door strip on the one hand and to the rotation about a vertical axis of the long foot on the other hand.
- a square secured on the one hand to the dashboard cross member and on the other hand to the front foot. This connection between the bracket and the front leg is achieved by a through screw, along the transverse axis of the vehicle. This screw associated with the square thus ensures the limitation of the rotation of the front leg, through which this screw passes.
- This solution has the major drawback of ensuring the transverse link between the dashboard cross member and the front foot only by the through screw.
- One of the objectives of the invention is therefore to propose a front foot structure which has less disadvantageous geometric characteristics in the event of an impact. Obtaining the non-rotation of the front foot is indeed one of the conditions necessary for holding the passenger compartment in the event of a frontal impact. The goal is therefore to use the mechanical capacities (effort following a direction transverse and a moment around a vertical direction) of the dashboard cross member to use it as a front foot rotation limiter.
- a second objective of the invention is to provide a connection between the front foot and the dashboard, the quality of which makes it possible to eliminate the through screw known in the state of the art.
- the present invention also aims to be inexpensive and space-saving.
- the invention proposes a front foot structure of the type presented above, characterized in that an internal box, on which the dashboard is fixed, is arranged on the face of the lining facing towards 'interior of the vehicle, in that an external housing is disposed on the face of the lining facing the outside of the vehicle, and in that these two housings are linked so as to constitute a substantially closed box.
- a slot is made in the front leg lining and allows the passage of a material strip specific to one of the boxes and covering the side of the other box. This material strip may belong to the internal housing and cover the side of the external housing, or belong to the external housing and cover the side of the internal housing.
- the housings are linked by solder points at the level of lugs extending them.
- the longitudinal dimension of the bracket is greater than the longitudinal dimension of the internal housing.
- the longitudinal faces of the two housings can have a through hole to allow the passage of a through screw, be solid faces.
- FIG. 1 is a schematic view of a front side structure of a motor vehicle, comprising a left front foot similar to the present invention.
- - Figure 2 is a perspective view of a left front leg structure according to the invention, seen from outside the vehicle at the left rear.
- - Figure 3 is a schematic view of a left front leg structure according to the invention, seen from above.
- - Figure 4 is a schematic view of a left front leg structure according to a particular embodiment of the invention, seen from above.
- - Figure 5 is a schematic view of a front left foot structure according to the invention, seen from above and after an impact.
- Figure 1 describes and shows a front foot structure 1 of a motor vehicle.
- the front foot 1 shown here is a left front foot.
- This front leg 1 is a structural node on which rests, inter alia, a wing support 2, an upright of a bay 3, a body side 4, a cross member of dashboard 5, a door strip 6 (which is articulated on this front leg) and a long leg 7.
- a frontal impact the rotation of this front leg 1 along a vertical axis therefore results in the deformation of the passenger compartment , which creates a risk in relation to passenger safety and which is therefore contrary to the specifications of car manufacturers.
- two housings 11, 12 are arranged on the front leg 1, at the height of the dashboard cross member 5.
- a first housing 11, called external casing, is arranged on the face of the leg front 1 facing outwards from the vehicle.
- a second housing 12, said internal housing is disposed on the face of the front leg 1 oriented towards the interior of the vehicle.
- These housings 11, respectively 12 are functionally separated by a lining 13 of the front leg 1. They have lugs 111, respectively 121 and are arranged opposite, linked by weld points at the legs 111 and 121, so that this assembly constitutes a substantially closed box.
- a pin 16, known as an "anti-burst pin” is secured to a transverse flank 113 of the external housing 11, and serves as a guide pin with the door strip 6, so as to produce a male-female coupling in the event of impact.
- the transverse dimension of the external housing 11 is larger than that of the internal housing 12.
- FIG. 2 represents this strip 15 covering the side of the external housing 11, facing the other side of the lining 13. It will be understood that the strip of material 15 passing through may belong equivalently to the external housing 11 and cover thus the side of the internal housing 12, facing the other side of the lining 13.
- this so-called through connection (the strip of material 15 passes through the foot lining 13) is conditioned by its alignment with the dashboard crosspiece 5 on the one hand, and by the number of weld points between the strip 15 through and the housing opposite, on the other hand.
- the strip of material 15 passing through has on the one hand the same height as the dashboard crossmember 5.
- this strip 15, belonging to a first housing 11, respectively 12 is welded with the second housing opposite 12, respectively 11, by three welding points.
- the connection between the front leg 1 and the dashboard 5 is double.
- the dashboard 5 is secured to a side of the internal housing 12 by two substantially longitudinal fasteners 23, 24.
- Figure 2 shows an embodiment in which the fastener 23 is located vertically at the dashboard crosspiece 5 and the fastener 24 is located below.
- the two fasteners 23 and 24 can be arranged equidistant from the dashboard crossmember 5, symmetrically placed with respect to the axis of the dashboard crossmember 5.
- a bracket 21 is secured to the dashboard crossmember 5, and this bracket 21 is connected to the front leg 1 by a through screw 22, oriented transversely and which, in the context of the invention, passes through the internal housing 12, the lining 13 of the front leg 1 and the external housing 11.
- the bracket 21 connecting the dashboard crossmember 5 and the front leg 1 is contained in a substantially horizontal plane and its length of cantilever L in the longitudinal direction of the vehicle is slightly greater than the length of the longitudinal faces 112, 122 boxes 11 and 12.
- Such geometrical arrangements allow, during an impact and the beginning of the rotation of the front leg 1, a support of the bracket 21 on the internal box 12 (cf. FIG. 5).
- the nature of this structure offers the possibility of eliminating the through screw 22.
- the internal box 12 passing through the lining 13 of the front foot 1 replaces the through screw 22 (cf. FIG. 5).
- This modification, associated with the square 21 of the dashboard 5, contributes by its geometric qualities, to improve the isostatism of the front foot.
- the front leg 1 is better locked in rotation around the vertical tax and promotes the good behavior of the passenger compartment in the event of a frontal impact.
- the significant reduction in the rotation of the front leg 1 along a vertical axis in the event of an impact thus makes it possible to remove the through screw 22, or, if this screw 22 is preserved, to relieve it from the absorption of the shock. It can also make it possible to remove the “anti-burst” pin 16, guide pin between the front leg 1 and the door strip 6 in the event of an impact.
