The present embodiment relates to a middle support structure of an instrument panel reinforcement beam, which can improve the stability of the instrument panel reinforcement beam 1 in supporting the instrument panel 6 and the overall structural rigidity of the mounting point; an exemplary configuration of which is shown in fig. 1 and 2.

In general, the middle support structure of the instrument panel reinforcement beam includes a main bracket 2 provided between the floor assembly and the instrument panel reinforcement beam 1, and a sub-bracket 5 provided on the main bracket 2. Wherein, the main support 2 supports in the middle part of instrument board stiffening beam 1, and auxiliary support 5 locates on the main support 2, and the one side of auxiliary support 5 towards instrument board 6 is equipped with the mounting point that is used for connecting instrument board 6 moreover.

There are of course various options for the placement and connection of the secondary support 5 on the primary support 2. For example, the sub-bracket 5 may be provided at a middle position of the main bracket 2, so long as the sub-bracket 5 has a portion protruding to the outside of the main bracket 2 on the side facing the instrument panel 6; this facilitates the installation of the mounting point at a position on the protruding portion of the sub-mount 5 where the instrument panel 6 is easily attached. Alternatively, the sub-bracket 5 is directly attached to the side of the main bracket 2 facing the instrument panel 6 to simplify the structural form of the sub-bracket 5.
