Description

Technical Field

[0001] The invention relates to a guide device for guiding a vehicle headlight in the event of a collision. The invention also relates to a vehicle having a front compartment structure and a vehicle headlight, wherein such a guide device is arranged between the vehicle headlight and the front compartment structure. Background Art

[0002] The vehicle has a front compartment which is formed by a bumper beam or bumper beams and longitudinal beams made of metal. The bumper beam and the longitudinal beams are connected to each other by diagonal braces in order to form a rigid front compartment structure in the event of a crash. The headlights are connected to the front compartment structure. Such a front compartment structure is known from DE 198 56 350 A1.

[0003] Furthermore, DE 10 2018 208 194 A1 discloses a fixing element for fixing a headlamp on a longitudinal beam in a front compartment of a motor vehicle. The fixing element comprises a connecting section extending in the longitudinal direction and a supporting arm extending in a direction transverse to the connecting section, wherein the connecting section extends from a rear region having a first contact surface for contacting a first surface of the longitudinal beam to a front region having a coupling section for fixing the headlamp, and a second contact surface is formed on the supporting arm for contacting a second surface of the longitudinal beam oriented offset from the first surface.

[0004] In the event of a crash, known front compartment structures have the disadvantage that the headlights penetrate and irreparably damage the support beams of the wheel arches that are fixed to the vehicle body, which results in a higher classification within the scope of the primary insurance classification, which leads to increased insurance costs. Summary of the invention

[0005] The object of the present invention is to provide a guide device and a vehicle which, in the event of a crash, prevent damage to the supporting beam of a wheel arch or limit it in such a way that no irreparable structural damage occurs.

[0006] To achieve this object, a guide device having the features of claim 1 and a vehicle having the features of claim 10 are proposed.

[0007] Advantageous embodiments of the guide device are the subject matter of the dependent claims.

[0008] According to a first aspect of the invention, a guide device for guiding a vehicle headlight in the event of a crash is provided, the guide device having a fastening section for fastening the guide device to the vehicle headlight and having a guide mechanism which is designed to transmit forces introduced into the vehicle headlight to a front compartment structure in the event of a crash.

[0009] Since the guide device reduces the forces introduced into the vehicle headlights via the front compartment structure in the event of a collision, the guide device prevents the vehicle headlights from penetrating the front compartment structure. As a result, the front compartment structure, in particular the support beams of the wheel arches, remain intact.

[0010] Currently, the vehicle headlamp is a front lighting lamp having a housing connected to a front compartment structure and at least one light-emitting device arranged in the housing.

[0011] Advantageously, the fastening section of the guide device is connected to a housing of the vehicle headlight.

[0012] The front compartment structure advantageously has at least one bumper cross member and a longitudinal member connected thereto, wherein the bumper cross member is connected to the longitudinal member via a strut-lock arrangement.

[0013] In an advantageous embodiment, the fastening section is designed as a tab having at least one fastening means for fastening the guide device to the vehicle headlight. The fastening means can have at least one hole for guiding a fastening element through which the fastening element is connected to the vehicle headlight, in particular to a housing of the vehicle headlight. Advantageously, the tab has a straight section with the fastening means and a curved section which is connected to the guide means, in particular to a curved connecting section of the guide means.

[0014] In an advantageous embodiment, the guide means transfers the forces introduced into the vehicle headlight in the event of a crash to the front compartment structure by deformation work. The guide means thus reduces the forces and energy introduced into the vehicle headlight in the event of a crash by deformation of the guide means. Furthermore, the deformation ensures a controlled movement of the vehicle headlight in the event of a crash.

[0015] In an advantageous embodiment, the guide mechanism has a guide section and a contact section, the guide section having a claw section, the claw section gripping and / or cutting into the vehicle headlight in the event of a collision, and the contact section abutting against the front compartment structure in the event of a collision. Thus, in the event of a collision, the guide mechanism is supported on the front compartment structure, in particular the support-lock structure, by the contact section and simultaneously grips and / or cuts into the vehicle headlight with the claw section. This prevents the vehicle headlight from penetrating the front compartment by discharging the introduced force by the support-lock structure and the support-lock structure remains undamaged. Advantageously, the claw section grips and / or cuts into the housing of the vehicle headlight. In an advantageous embodiment, the claw section is configured as a sharp edge for gripping and / or for cutting into. Advantageously, the guide mechanism has two opposing claw sections. Advantageously, the contact section extends in the vehicle height direction and the claw section extends in the vehicle transverse direction.

[0016] In an advantageous embodiment, the claw section is designed as a conically tapering projection, which is sharp-edged at its free end. The conically tapering projection thus grips and / or cuts into the vehicle headlight, in particular into a housing of the vehicle headlight. In an advantageous embodiment, the guide device has two opposite conically tapering projections, which are sharp-edged at their free ends.

[0017] In an advantageous embodiment, the guide device has a curved connecting section which connects the guide section and the fastening section to one another. The curved connecting section ensures that the guide device is deployed in the event of a crash and thus that the vehicle headlight is pressed outward, ie away from the vehicle, in the event of a crash.

[0018] In an advantageous embodiment, the curved section has an S-shape. The S-shape or the S-shaped profile deforms during a crash, so that the forces introduced into the vehicle headlight are relieved. In addition, the vehicle headlight is pressed outwards due to the deformed S-shaped profile, so that the vehicle headlight does not penetrate the front compartment structure.

[0019] In an advantageous embodiment, the guide section is designed as a cup-shaped web which is connected to the fastening section via a curved connecting section.

[0020] In an advantageous embodiment, a section of the surrounding edge of the tub-shaped web forms the contact section, wherein a conically tapering projection projects from the surrounding edge. Advantageously, two opposite conically tapering projections project from the edge section. Advantageously, the section of the surrounding edge forming the contact section faces the support-locking structure. Furthermore, advantageously, the curved connecting section transitions into the surrounding edge forming the contact section. Furthermore, advantageously, the conically tapering projection projects vertically from the surrounding edge in the transverse direction of the vehicle. Furthermore, the projection advantageously projects from the surrounding edge at the free end of the tub-shaped web opposite the contact section.

[0021] In an advantageous embodiment, the guide device is a one-piece sheet metal part produced by bending, stamping and / or deep drawing. Advantageously, the sheet metal part has a thickness between 1.5 mm and 4 mm, in particular 2.5 mm.

[0022] According to a further aspect of the invention, a vehicle is proposed having a front compartment structure and a vehicle headlight, wherein the guide device according to the invention is arranged between the vehicle headlight and the front compartment structure.

[0031] exist Figure 1 A vehicle 10 is shown having a Figure 4 1 and 2 , a front compartment structure 12 of a pillar-lock structure 14 and a vehicle headlamp 16 arranged on the front compartment structure 12 are shown.

[0032] As in Figure 4 It can be seen that a guide device 20 is provided between the vehicle headlight 16 and the front compartment structure 12 , in particular the pillar-lock structure 14 , which prevents the vehicle headlight 16 from penetrating the front compartment structure 12 in the event of a crash, as will be explained in greater detail below.

[0033] The guide device 20 is a one-piece sheet metal part produced by bending, stamping and / or deep drawing. The sheet metal part has a thickness between 1.5 mm and 4 mm, in particular 2.5 mm.

[0034] The guiding device 20 is based on Figure 2 and Figure 3 It has a fastening section 22 for fastening the guide device 20 to the vehicle headlight 16 and has a guide mechanism 24 .

[0035] The fastening section 22 is designed as a web 26 having a straight section 34 and a curved section 36. The guide means 24 is connected to the curved section 36.

[0036] As in Figure 5, the fastening section 22 is connected to a housing 32 of the vehicle headlight 16. For this purpose, a fastening means 28 in the form of an opening 30 for guiding a fastening means (not shown) through is introduced into the straight section 34, which fastening means can be screwed into the housing 32 of the vehicle headlight 16.

[0037] The guide means 24 has a guide section 38 and a curved connecting section 40 which connects the guide section 38 to the fastening section 22 .

[0038] The curved section 36 transitions into a curved connecting section 40, wherein the curved connecting section 40 forms an S-shaped contour or S-shaped portion 42, as shown in particular in Figure 2 and 4 Visible in.

[0039] The guide section 38 is designed as a cup-shaped web 44 and has two claw sections 46 and a contact section 48 .

[0040] The claw section 46 is designed as a conically tapering projection 50 which projects from the circumferential edge 47 of the pot-shaped web 44 along the vehicle transverse axis Q, as shown in FIG. Figure 2 and 3 As can be seen in FIG. 5 , the conically tapering projection 50 is designed to be sharp-edged at its free end 52 .

[0041] The curved connecting section 40 transitions into a contact section 48, which is formed by a section of the surrounding edge 47. The contact section 48 extends on the vehicle vertical axis H, as in particular at Figure 5 and facing the pillar-lock structure 18, as shown in Figure 4 , 6 and 7.

[0042] If through Figure 6 and Figure 7 As can be seen from the overview of FIG. 5 , in the event of a crash, the sharp free end 52 of the conically tapering projection 50 grips and / or cuts into the housing 32, and at the same time the contact section 48 contacts the pillar-locking structure 18 and the S-shaped section 42 deforms. As a result, the guide device 24 transmits the forces introduced into the vehicle headlight 18 to the pillar-locking structure 18 in the event of a crash and thus prevents the vehicle headlight 16 from penetrating the front compartment structure 14, as in the case of a crash. Figure 7 As shown in . Therefore, the pillar-lock structure 18 remains intact.

[0043] Since the guide device 20 reduces the forces introduced into the vehicle headlights 16 via the front vehicle body structure 12 in the event of a crash, the guide device 20 prevents the vehicle headlights 16 from penetrating the front vehicle body structure 12. As a result, the front vehicle body structure 12, in particular the supporting beams of the wheel arches, remain intact.
