2 illustrates a cow cross member according to an embodiment of the present invention.
3 illustrates the connection of a cow cross member and a steering column according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

The front module of the vehicle according to the present invention comprises an integral type crush pad 100 constituting an interior panel of the vehicle at its upper portion and extending to the bottom portion of the vehicle to form a boundary between the engine room and the driver's seat; And a crush box 210 extending across the vehicle from the engine compartment side to the integrated crushpads side 100 and provided with a crush box 210 extending toward the front of the vehicle. When an end of the crush box 210 supports the engine, And a cow cross member 200 for preventing the cow cross member 200 from being pushed by the driver's seat.

The integrated type crush pad 100 according to the present invention has a shape extending to the lower end to a position where the dash panel is present due to the removal of the dash panel which is the boundary between the engine room and the driver's seat. Therefore, it plays a role of distinguishing the engine room, which is the role of the dash panel, from the interior. Also, it plays a role of blocking the noise caused by the operation of the engine.

In the conventional case, the crush pad 100 and the dash panel are separated, but the crush pad 100 according to the present invention functions as two parts as a whole. As a result, the manufacturing process can be simplified and productivity can be expected to be improved, and the noise can be removed by the rigidity of the dash panel itself.

Also, if a dash panel is present, welding is required to join the dash panel, the cowl panel, the dash panel and the A pillar. As a result, there is a problem in that a welding fault occurs due to an increase in the number of welded portions of the multi-ply. As described above, since the crush pad 100 can be fixed to the vehicle body using bolting or the like by extending the crush pad 100, It was possible to solve it.

Furthermore, by using the carbon fiber reinforced plastic as the material of the crush pad 100, it is possible to expect the crush pad 100 having a high strength and a role as a finishing material.

In the case of the cow cross member 200 according to the present invention, since the dash panel is omitted, it is necessary to mount a function of preventing the engine from being pushed to the driver's seat during collision, which is one of the main roles of the dash panel. Therefore, the crush box 210 having the function of preventing engine thrust is provided on the cowl cross member 200.

The crush box 210 is located on the cowl cross member 200 and extends forward of the vehicle to support the engine. In the case where the dash panel performs such a role as described above, the problem of welding failure or the like, which was described above, can not sufficiently prevent the engine jamming phenomenon at the time of collision, resulting in serious consequences.

In order to solve such a problem, the cow cross member 200, which is stably mounted on the vehicle body, is provided with a function of preventing the engine from being thrown, thereby enabling the design of the vehicle in which the safety of the driver is further improved.

The technical idea of the present invention is to eliminate the dash panel having various problems as described above, and the role of the dash panel is shared by the integral type of the crush pad 100 and the cowl cross member 200, thereby solving the problems of the conventional dash panel The function of the dash panel is to construct a front module of the enhanced vehicle.

The extended lower end of the integrated crush pad 100 may be fixed to the floor panel of the vehicle.

The crush pad 100 according to the present invention, which replaces the position of the dash panel, is fixed to the cowl panel and the A pillar. In addition, the crush pad 100 is fixed to the floor panel of the vehicle.

Further, the crush pad 100 is extended to be fixed to the floor so that the engine room and the room are completely separated, thereby making it possible to more effectively block the engine noise. And also has an advantage of being able to support the engine throttle prevention function performed by the cow cross member 200. [

The integral type crush pad 100 may be formed of a carbon fiber-reinforced plastic material.

When the carbon fiber reinforced plastic is used as a material, the high strength of the vehicle can be achieved while reducing the weight of the vehicle due to the inherent characteristics of the material. Therefore, even if the dash panel requiring high strength is removed, the crush pad 100 can replace the role.

In addition, the weight of the vehicle can be reduced and the fuel efficiency of the vehicle can be expected to be improved. The carbon fiber reinforced plastic itself can also serve as a finishing material according to the texture of the carbon fiber reinforced plastic itself, thereby having an additional advantage that the design can be advanced without a separate finishing process.

The upper part of the integral type crush pad 100 is bent to protrude to the passenger side and the lower part of the integral type crush pad 100 extends in the height direction of the vehicle. In addition, a convenience device including an instrument module, an audio module, and a storage box may be installed on an upper portion of the integral type crusher 100. [

The cowl cross member comprises a horizontal bar 220 transversely transverse to the vehicle, a vertical bar 230 extending downwardly from the horizontal bar 220 and connected to the bottom, and a horizontal bar 220 connecting the horizontal bar 220 with the cowl panel. And a mounting portion 240 for fixing the mounting portion 220. The horizontal bar 220 may include a plurality of bars spaced apart from each other and mounted on the A pillars. The vertical bar 230 may extend downward from the uppermost horizontal bar 220, And a plurality of bars that intersect the bar 220.

Generally, in the case of the cow cross member 200, one horizontal bar 220 having both ends mounted on the A pillar of the car body and one vertical bar 230 mounting the lower end of the car body to the floor panel. However, in such a cow cross member 200, not only the instability of the structure itself but also insufficient torsional stiffness due to a lack of a portion to be mounted on the vehicle body.

In the case of the cow cross member 200 according to the present invention, the cow cross member 200 has a plurality of horizontal bars 220 and vertical bars 230 and has a lattice shape. Such a cow cross member 200 has a more stable structure, The mounting portion is increased, and the above-mentioned problem can be solved.

By increasing the torsional rigidity, the ability to cope with torsion at the corner is improved, driving performance is improved and steering is enhanced. Further, durability can be improved and higher stability can be obtained.

In one embodiment of the present invention, the upper portion of the integrated type crush pad 100 surrounds the plurality of horizontal bars 220 and fixes the abutting portions thereof. The lower portion of the integrated type crush pad 100 surrounds the plurality of vertical bars 230, 100 and the lattice-shaped cowl cross member 200 are more tightly adhered to each other to improve the integrity of the vehicle.

The crush box 210 may be extended from the plurality of vertical bars 230 toward the front of the vehicle.

Instead of omitting the dash panel as described above, the cow cross member 200 must perform the engine throttle prevention function of the dash panel. When the shape of the cowl cross member 200 is a lattice structure, the crush box 210 having the function of preventing engine thrust is positioned on the plurality of vertical bars 230 and extends forward of the vehicle to support the engine .

When the cow cross member 200 is in a lattice shape, a plurality of crush boxes 210 can be formed, so that the engine room can be supported more stably. As a result, it is expected that the function of preventing engine throttle will be further improved. This makes it possible to further omit the dash panel.

The plurality of horizontal bars 220 and the vertical bars 230 of the cow cross member 200 are formed in a pipe shape so that the wiring harness of the electronic equipment is penetrated into the inside of the pipe.

The wiring harness functions to drive the vehicle and deliver the necessary electricity to each part to operate the functional part. In the case of the wire harness having such an important role, the cowl cross member 200 is configured to be pipe-shaped as in the present invention so as to respond sensitively to damage, so that the wiring harness penetrates the inside and effectively protects it from external factors .

The steering column 300 is passed through the space between the plurality of horizontal bars 220 and the steering column 300 is inclined so that the plurality of horizontal bars 220 positioned above and below the steering column 300 And the upper and lower ends are supported.

One of the roles of the cowl cross member 200 is to support the steering column 300 by fixing it. In the conventional case, a separate panel is installed to fix the steering column 300 to the cowl cross member 200, The through hole of the steering column 300 must be provided in the member 200 itself.

In the case of the cow cross member 200 according to the present invention, since the plurality of horizontal bars 220 are present, the steering column 300 can pass through the plurality of horizontal bars 220 to be stably fixed and supported, . ≪ / RTI >

The integral type crush pad 100 is provided with an electric wire hole through which the electric wire of the convenience equipment can be mounted on the bottom surface where the recessed portion is formed in the front side of the vehicle so that the convenience equipment of the vehicle can be seated, (100) and a convenience device are integrally provided.

On the crush pad 100, a variety of convenience equipment such as an air conditioner audio navigation device and the like can be installed. In order that the convenience equipment can be stably stowed, a seating part depressed toward the front of the vehicle can be formed and the convenience equipment can be positioned on the seat part.

Also, since the electric wire holes are provided on the crush pad 100 so that the electric wire of the convenience device can penetrate, the effect that the crush pad 100 and the convenience equipment are stably positioned can be expected.
