Definitions
- the present invention relates to a front lid hinge with the features of the preamble of patent claim 1 and a motor vehicle with such a front lid hinge.
- Front lid hinges for motor vehicles for pivotally mounting a front lid on a body of the motor vehicle are known from the prior art in various configurations.
- the DE 10 2015 109 128 B3 describes a front lid hinge for a motor vehicle with a first hinge leg and a second hinge leg, which are articulated to one another for opening and closing a hood.
- one of the two hinge legs includes a base component and a pivoting element with a first storage area on the body side and a second storage area on the hood side.
- the pivoting element has a floating bearing in one of the two storage areas, so that the pivoting element can be unlocked by a rotational movement and can be raised from a basic position to an impact position.
- the floating bearing of the front flap hinge known from DE 102015 109 128 B3 enables the hood to be pivoted in a defined manner for pedestrian protection. Due to the design of the floating bearing, the floating bearing has a constant rigidity in various crash situations.
- a front lid hinge for a motor vehicle which comprises an upper hinge part and a front lid fastening element.
- the front flap fastening element can be attached to a front flap of the motor vehicle and is pivotally connected to the upper hinge part about a first pivot axis which extends in the transverse direction, in particular in a functional installed state of the front flap hinge on the motor vehicle in the transverse direction of the motor vehicle.
- the upper hinge part includes a guide element. In the guide element, a guide counter-element of the front lid fastening element is guided in a first crash event.
- the guide element and the guide counter-element are designed such that the guide counter-element can be removed from the guide element in a second crash.
- the core idea of the invention is therefore to design the guide element and the guide counter-element in such a way that they control a relative movement of the front flap fastening element to the upper hinge part in a defined manner in the first crash case, whereas in the second crash case the guide counter-element can be removed from the guide element, so that the front flap fastening element can move relative to the hinge part, without the relative movement being influenced by the guide element and the guide counter element.
- the front lid hinge according to the invention therefore has a different stiffness in the first crash case than in the second crash case.
- the transverse direction corresponds to a transverse direction of the motor vehicle in a functional installed state of the front lid hinge in the motor vehicle.
- the front flap fastening element is pivotally connected to the upper hinge part, for example about a first pivot axis extending in the transverse direction, in such a way that in the first crash case the front flap can be pivoted in such a way that a region of the front flap arranged in the longitudinal direction in front of the front flap fastening element is pivoted downwards in the vertical direction and a region of the front flap arranged in the longitudinal direction behind the front flap fastening element is pivoted upwards in the vertical direction.
- the longitudinal direction corresponds to a motor vehicle longitudinal direction in a functional installed state of the front lid hinge on the motor vehicle.
- the vertical direction corresponds to a motor vehicle vertical direction in a functional installed state of the front lid hinge in the motor vehicle.
- the guide element is in the second crash case by displacing the guide counter-element relative to the guide element in the transverse direction and / or by pivoting the guide counter-element about a second pivot axis, in particular in the vertical direction, relative to the guide element can be removed from the guide element.
- the second pivot axis can extend through a joint via which the front flap is connected to the upper hinge part so that it can pivot about the first pivot axis.
- the guide element is a guide slot, i.e. an elongated hole.
- the guide counter element is, for example, a guide pin which is arranged in the guide link.
- the guide backdrop is, for example, circular arc-shaped.
- the concave side of the guide link can be at the front in the longitudinal direction.
- the guide element is open in an upper region in the vertical direction and at the rear in the longitudinal direction, in particular in a convex region of the guide link.
- the guide element therefore comprises a recess in the upper region in the vertical direction and at the rear in the longitudinal direction. Through the recess, the guide counter element can be removed from the guide element in the second crash case.
- the guide counter element can include a bolt body and a bolt head.
- the guide element has such a length, i.e. such an extension in the transverse direction, and / or the guide counter-element has such a play in the guide element, i.e. such a distance from the guide element, that the guide counter-element in the Second crash case can be removed from the guide element by pivoting about the second pivot axis.
- the guide counter element can consist of a, in particular cylindrical, bolt body, ie it cannot include a bolt head.
- the first crash event is a front crash.
- a force acts on the motor vehicle in the longitudinal direction and/or in the vertical direction, i.e. no force in the transverse direction, or a force that acts on the motor vehicle in the transverse direction of the motor vehicle is below a threshold value.
- the front lid hinge is free from any transverse force.
- a force in the longitudinal direction and/or a force in the vertical direction acts on the front flap hinge, in particular on the upper hinge part.
- the second crash event is a front crash, a side crash or an oblique crash.
- the defined threshold value for example, has such a size that when a force equal to the defined threshold value acts on the front flap hinge, the guide counter element can be removed from the guide element.
- the guide element comprises, at its upper end in the vertical direction, a recess which extends forward in the longitudinal direction.
- the guide element can be moved into the recess, in which it is secured against being moved downwards in the guide element in the vertical direction.
- the front lid hinge according to the invention comprises a lower hinge part that can be rigidly fixed to a body of the motor vehicle.
- the upper hinge part can be pivotally connected to the lower hinge part via at least one link, in particular two links.
- the front flap can thus be mounted on the body so that it can pivot about a third pivot axis extending in the transverse direction via the front flap hinge.
- the invention further relates to a motor vehicle, comprising a front lid hinge described above.
- the motor vehicle according to the invention comprises two front lid hinges described above.
- the motor vehicle according to the invention can have a front lid and a body.
- the front flap fastening element is, for example, rigidly connected to the front flap.
- the lower hinge part can be rigidly fixed to the body of the motor vehicle.
- the front flap can thus be fixed to the body so that it can pivot relative to the body by means of the front flap hinge according to the invention.
- Fig. 1 is a perspective view of a portion of a motor vehicle according to the invention.
- Fig. 2 is a detailed view of partial area A from Fig. 1, without showing a front flap;
- Fig. 3 is a detailed view of the partial area B from Fig. 2.
- the motor vehicle 2 comprises a body 8 and a front lid 6.
- the front lid 6 is mounted on the body 8 so as to be pivotable about a pivot axis extending in the transverse direction of the motor vehicle via two front lid hinges 4.
- the front lid hinges 4 are arranged mirror-symmetrically to a motor vehicle longitudinal center plane in a rear area in the vehicle's longitudinal direction and in an outer area in the vehicle's transverse direction on an underside of the front lid 6.
- the front flap hinges 4 are designed to be mirror-symmetrical, the following description is limited to the right front flap hinge 4 in the forward direction of travel, with the following statements correspondingly applying to the left front flap hinge in the forward direction of travel.
- the front flap hinge 4 comprises, as can be seen in particular from the detailed view of the area A from FIG. 1 shown in FIG.
- the lower hinge part 22 is rigidly fixed to the body 8.
- the two links 24 connect the upper hinge part 10 to the lower hinge parts 22 about a pivot axis extending in the transverse direction of the motor vehicle.
- the upper hinge part 10 is pivotally connected to the front lid fastening element 12 about a further pivot axis extending in the transverse direction of the motor vehicle.
- the front flap fastening element 12 is rigidly fixed to an underside of the front flap 6.
- the guide element 14 is a circular arc-shaped guide link.
- the guide counter element 16 is a guide pin that extends in the transverse direction of the motor vehicle and is arranged in the guide link. In a first crash case, in which only a force acts on the front lid hinge 4 in the vehicle's longitudinal direction and in the vehicle's vertical direction, the guide counter element 16 is displaced upwards in the guide element 14 in the vehicle's vertical direction.
- the concave side of the guide link points forward in the longitudinal direction of the vehicle.
- the guide element 14 At an upper end in the vertical direction of the motor vehicle, the guide element 14 comprises a recess 20.
- the recess 20 extends forward from the guide element 14 in the longitudinal direction of the motor vehicle.
- the guide counter element 16 is moved into the recess 20 due to a relative movement of the front lid fastening element 12 to the upper hinge part 10, in particular in the context of the first crash, the guide counter element 16 and therefore the front lid fastening element 12 is protected from a relative movement in the vertical direction of the vehicle downwards by support secured on a wall defining the recess 20.
- the guide element 14 comprises a recess 18 in an upper region in the vertical direction of the motor vehicle, on the rear side in the longitudinal direction of the motor vehicle, in particular on the convex side.
- the guide element 14 is therefore in the upper region in the vertical direction of the motor vehicle in the longitudinal direction of the motor vehicle
- the rear side is open.
