[0001] Crash damper for vehicle [

Embodiments of the present invention relate to a vehicle impact reduction device. More particularly, the present invention relates to a shock absorber capable of absorbing an impact when a vehicle collides with a pedestrian.

In general, automotive brackets and frames are being developed with high rigidity to withstand vehicle vibrations and maintain geometric dimensions between adjacent components. However, as the stiffness of these brackets increases, there is a problem that the damage of the pedestrian increases when the vehicle collides with the pedestrian.

Particularly, the development of vehicle parts is mainly focused on the safety of the vehicle and the driver, so the damage to the vehicle and the driver is reduced while the damage to the pedestrian is increasing. In recent years, in order to reduce the damage of pedestrians, the regulations relating to vehicle parts for pedestrian safety have been established. In particular, the requirements related to the upper leg form of the vehicle for absorbing the impact of the pedestrian have become important design elements of the vehicle It is emerging as one.

However, since the parts of the vehicle have to have high rigidity in order to withstand the vibration of the vehicle and maintain the shape dimensions, there is a conflict between the measures for absorbing the impact of the pedestrian, It is difficult to prepare.

FIG. 1 is a schematic perspective view of a shock absorber for a vehicle according to an embodiment of the present invention, and FIG. 2 is a perspective view for explaining the shock absorber shown in FIG.

Referring to FIGS. 1 and 2, a vehicle shock absorber 100 according to an embodiment of the present invention absorbs shock applied to an upper leg form of a vehicle from the outside, And can be used to stably support the headlamp 10.

Specifically, the shock absorber 100 may be disposed under the head lamp 10 in the interior of the vehicle, and may include a guide plate 110 and a sliding plate 120.

The lower portion 112 of the guide plate 110 may be coupled to the lower member of the vehicle. In an embodiment of the present invention, the bumper beam 20 may be used as the lower member of the vehicle to which the guide plate 110 is coupled.

The sliding plate 120 is disposed to face the guide plate 110 and the upper portion 122 is coupled to the lower portion of the head lamp 10 to support the head lamp 10. The sliding plate 120 faces the guide plate 110 so that the sliding plate 120 can slide downward along the guide plate 110. The sliding plate 120 is disposed in contact with the guide plate 110.

One of the guide plate 110 and the sliding plate 120 has a plurality of insertion holes 124 arranged in a direction in which the sliding plate 120 slides, And a fixing protrusion 114 for fixing the position of the sliding plate 120.

In one embodiment of the present invention, the insertion holes 124 are formed in the sliding plate 120, and the fixing protrusions 114 are provided in the guide plate 110.

Since the fixing protrusion 114 is inserted into the insertion holes 124 and the position of the sliding plate 120 is fixed, the impact reducing device 100 stably supports the head lamp 10 can do.

In particular, the guide plates 110 and the sliding plates 120 are in contact with the surfaces 116 and 126, and the sliding plates 120 are disposed below the guide plates 110. Since the guide plate 110 and the sliding plate 120 are formed of the inclined surfaces 116 and 126, the head lamp 10 can be more stably supported from the vibration of the vehicle.

The inclined surface 116 of the guide plate 110 and the inclined surface 126 of the sliding plate 120 are inclined at the same angle with respect to the ground surface and the inclined surfaces 116 and 126 ) May be from about 30 [deg.] To about 50 [deg.].

The fixing protrusion 114 is formed on the inclined surface 116 of the guide plate 110 and the insertion holes 124 are formed on the inclined surface 126 of the sliding plate 120.

FIG. 3 is an enlarged view for explaining the insertion holes and the fixing protrusion shown in FIG. 2, and FIG. 4 is a partial sectional view for explaining the coupling relation between the insertion holes and the fixing protrusion shown in FIG.

3 and 4, in one embodiment of the present invention, the insertion holes 124 may be formed of three insertion holes 124A, 124B, and 124B, Are not limited thereto.

Each of the insertion holes 124A, 124B, and 124C can be formed in a circular shape. Particularly, the insertion holes 124A, 124B and 124C can move downward along the guide plate 110 by the pressure applied to the headlamp 10 from the outside of the vehicle by the sliding plate 120 The two insertion holes adjacent to each other are formed to communicate with each other as shown in FIG. Accordingly, the fixing protrusion 114 can move between the insertion holes 124A, 124B and 124C by the external pressure.

That is, in the initial assembly of the vehicle, the fixing protrusion 114 may be inserted into the insertion hole 124C positioned at the lower side as shown in FIG. Thereafter, when an impact is applied to the headlamp 10 from the outside of the vehicle in the course of driving the vehicle, the sliding plate 120 is slid downward along the guide plate 110 by the impact, The insertion hole into which the fixing protrusion 114 is inserted can be changed to the insertion hole 124A located at the uppermost position or the insertion hole 124B positioned immediately below the insertion hole by the movement of the plate 120. [ At this time, the insertion hole into which the fixing protrusion 114 is inserted may vary according to the intensity of the external pressure. In addition, the hole size of the portion where the two adjacent insertion holes are connected is smaller than the diameter of the insertion holes 124A, 124B, and 124C so that the fixing protrusion 114 can be prevented from moving below an appropriate impact value have.

As described above, the vehicle impact reducing apparatus 100 includes the guide plate 110 and the sliding plate 120 that are slidably supported by the external impact while supporting the headlamp 10, It is possible to stably support the headlamp 10 in response to the vibration of the headlamp 10 and the impact applied to the headlamp 10 from the outside and effectively absorb the impact applied to the headlamp 10, It is possible to protect the pedestrian by reducing the impact of the pedestrian.

Further, since the guide plate 110 and the sliding plate 120 are provided in an inclined surface, the head lamp 10 can be more stably supported in response to vibration and external impact of the vehicle, .

The sliding plate 120 can move downward by the external pressure transmitted from the head lamp 10 while maintaining the engagement with the guide plate 110 by the fixing protrusion 114, 110). ≪ / RTI > Accordingly, the head lamp 10 can be stably supported while efficiently absorbing the impact due to the external pressure.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the present invention as defined by the following claims. It can be understood that it is possible.

10: head lamp 20: bumper beam
100: Vehicle impact reducing device 110: Guide plate
114: fixing protrusion 120: sliding plate
124: insertion hole
