Abstract
The present invention is further configured by welding the reinforcement block formed to be assembled on the front center upper portion of the bumper beam, and additionally increases or decreases the number of reinforcement blocks to correspond to the bumper beams having various lengths for each vehicle. It can be used in multiple vehicles, and its structural rigidity is improved without increasing the overall size of the bumper beams, thereby improving the impact absorption performance of the bumper beams against frontal collisions. To prevent underriding
In the vehicle bumper beam unit comprising a bumper beam that is integrally formed by extrusion molding and disposed in the vehicle width direction, a locking protrusion is integrally formed at a rear upper portion along the longitudinal direction of the bumper beam, and a plurality of mutually assembleable configurations are possible. And a reinforce block which is assembled in an optional number according to the collision demand performance of the bumper beam and is mounted along the longitudinal direction in the upper center of the bumper beam.
Description
The present invention relates to a bumper beam unit for a vehicle, and more particularly, a reinforce block that can be selectively assembled according to the bumper beam collision demand performance on the front center of the bumper beam to improve rigidity of the bumper beam against frontal collision. A bumper beam unit for a vehicle is provided.
In general, a bumper in a vehicle absorbs an impact when a vehicle collides with another vehicle or a fixed body to promote passenger safety, and at the same time, a predetermined portion of the front and rear ends of the vehicle can be minimized to minimize deformation of the vehicle body. The buffer unit is arranged.
As shown in FIG. 1, the
Here, the above-mentioned conventional
The corner reinforcement
On the other hand, the linear beams such as the
In addition, in recent years, in accordance with the trend toward lighter weight of vehicles, the bumper beam is manufactured and applied integrally by extrusion molding from aluminum.
However, when the material is changed to reinforce the stiffness of the
In addition, the conventional vehicle
Therefore, the present invention has been invented to solve the problems as described above, the problem to be solved by the present invention by additionally configured by welding the reinforcement block formed to be assembled on the front center upper portion of the bumper beam, The number of reinforced blocks can be selectively increased or applied to the bumper beams having various lengths, so that they can be applied to multiple vehicles, and the structural rigidity is increased without increasing the overall size of the bumper beams. It is to provide a vehicle bumper beam unit to improve the absorption performance.
In the bumper beam unit for a vehicle according to an embodiment of the present invention for achieving the above object in the vehicle bumper beam unit comprising a bumper beam is formed integrally by extrusion molding in the vehicle width direction, the longitudinal direction of the bumper beam Accordingly, the locking protrusion is integrally formed at the rear upper portion, and is configured to be assembled to a plurality of mutually, and is assembled in an optional number according to the collision demand performance of the bumper beam through the locking protrusion along the longitudinal direction in the upper center of the bumper beam. It further includes a fixed reinforcement block.
Each of the reinforcement blocks may include: a main body having a locking groove formed at a rear side thereof in a longitudinal direction corresponding to the locking protrusion; A fitting protrusion protruding from one side of the main body; And fitting grooves formed on the other side of the main body in correspondence with the fitting protrusions.
The main body has a predetermined height from the top surface of the bumper beam, characterized in that formed in a hollow block shape.
The fitting protrusion extends protruding from one side of the main body; And a fitting portion formed at an end of the extension portion in a vertical direction with the extension portion.
The fitting groove is formed as a groove having the same shape as the fitting protrusion, characterized in that the locking end is formed on each side so that the fitting portion is caught around the extension of the fitting protrusion.
Each of the reinforcement block is characterized in that the fitting protrusion of one reinforcement block is fitted into the fitting groove of the other reinforcement block is assembled with each other.
The locking projection includes a bending end that is bent toward the front surface of the bumper beam, and the bending end is inserted into the locking groove of the main body.
The reinforce block is characterized in that the front lower portion of the main body in contact with the bumper beam is welded and fixed along the longitudinal direction of the bumper beam in a state in which the bent end of the locking projection is fitted in the locking groove.
The bumper beam and the reinforce block are made of aluminum.
As described above, according to the vehicle bumper beam unit according to the embodiment of the present invention, by additionally configured by welding the reinforcement block formed so as to be assembled to the upper front center of the bumper beam, the configuration without increasing the overall size of the bumper beam Increasing the structural rigidity has the effect of improving the shock-absorbing performance of the bumper beam against the frontal impact.
In addition, since the reinforce block is formed of an aluminum material having the same material as that of the bumper beam in a prefabricated structure that can be assembled together without bolting or welding, the overall weight of the bumper beam unit is reduced, and at the same time, the quality of corrosion prevention such as corrosion The problem can be prevented in advance, and the number of reinforce blocks can be selectively increased or decreased according to the collision demand performance in response to bumper beams having various lengths for each vehicle type, thereby making it common to multiple vehicles.
In addition, by configuring a plurality of reinforcement block in the upper part of the center of the bumper beam in the assembled state, the under-ride that pushes into the lower part of the opponent vehicle when the front or rear collision with a vehicle with a relatively high garage (Under) It also has the effect of improving the structural stability of the bumper beam, such as preventing the shape of the riding to prevent damage to the vehicle body.
