Description

  The present invention relates to a toeboard reinforcing structure for a vehicle having a toeboard that partitions an engine room and a vehicle compartment in the front-rear direction.

Conventionally, as a vehicle body structure provided with the toe board of the above example, there are structures described in Patent Document 1 and Patent Document 2.
That is, the structure described in Patent Document 1 includes a toe board that partitions the engine room and the vehicle interior in the front-rear direction, and a steering support member stay that connects the steering support member and the floor tunnel portion. The tunnel portion attached to the tunnel portion is reinforced by the front and rear reinforcing plates. According to this reinforcing structure, the rigidity of the steering support member stay and the rigidity of the tunnel portion can be improved. The technical idea of preventing the toe board from retreating at the time of a collision (particularly at the time of a frontal collision) is not disclosed.

The structure described in Patent Document 2, arranged a reinforcement on the front lower side of the tunnel portion of the floor panel, projecting the front end portion of the reinforcement to the front of the vehicle body than the toe board, the reinforcement The vertical surface of the front end is opposed to the lower part of the rear surface of the power train, and the above-mentioned reinforcement is crashed at the time of a vehicle collision to absorb the load.

  According to the structure disclosed in Patent Document 2, a crash space can be secured by the above-mentioned reinforcement. However, since the reinforcement does not improve the resistance to a collision, the toe board is prevented from moving backward. There was a problem that it was difficult to balance the space for passengers and passengers.

On the other hand, although the toe board is configured so as not to retreat as much as possible in the conventional vehicle body structure, in recent years, the demand for toe board retraction prevention at the time of a collision is increasing, and the rear part in the vicinity of the toe board There is a demand for a vehicle body structure that efficiently prevents the toe board from moving backward so as not to interfere with the air conditioning unit disposed in the vehicle.

  Therefore, the present invention provides a reduction (reduced) between the toe board that partitions the vehicle compartment and the engine room and the lower member that extends in the vehicle width direction above the floor panel in the event of a vehicle collision. By arranging the air conditioning unit to interfere with this and prevent the toe board from moving backward, it is possible to efficiently prevent the toe board from moving backward by using the lower member. The purpose of the present invention is to provide a toeboard reinforcing structure for a vehicle that can secure both space and safety.

A toeboard reinforcing structure for a vehicle according to the present invention is a toeboard reinforcing structure for a vehicle provided with a toeboard that partitions a vehicle interior from an engine room, and a floor panel extends continuously rearward from the toeboard, and the floor A steering support member stay to which a steering support member is attached is provided at a position spaced apart from the toe board of the panel by a predetermined distance. The steering support member is stretched between left and right vehicle body rigid members in the vehicle interior, A lower member is provided below the steering support member and extending in the vehicle width direction at a predetermined interval above the floor panel and connected to the left and right vehicle body rigid members. The lower member has the same height as the lower member of the toe board. In this position, a dash lower cross member is extended in the vehicle width direction, and the lower When the distance between the toe board and the lower member approaches between the toe board and the toe board, an air conditioning unit is installed between the lower member and the dash lower cross member to interfere with this and prevent the toe board from moving backward. disposed at the same height position as the lower member between said lower member and the dash lower cross member, a heater core or an evaporator disposed in the air-conditioning unit case is disposed substantially horizontally, and the lower member and the toe board A reinforcing bracket is disposed between the front end of the reinforcing bracket and the rear end of the reinforcing bracket is connected to the lower lower member .

  According to the above configuration, sufficient steering support rigidity and vehicle body rigidity can be secured by a total of two members extending in the vehicle width direction of the steering support member and the lower member, and of course, between the lower member and the dash cross member. Since the air-conditioning unit is disposed in the front, the lower member can be effectively used to prevent the toe board from retreating efficiently.
