Abstract

The present invention relates to a support structure for a high-voltage component for a vehicle. A support structure (10) for supporting a flat-plate-shaped inverter (30) between seats (11L, 11R) arranged in the vehicle width direction, wherein the inverter (30) is supported in a horizontal state by a bracket (20) so as to be separated upward from a floor tunnel (13) of a floor in a vehicle interior between the seats (11L, 11R), the bracket (20) has a pair of rear legs (21 RL, 21 RR) arranged in the vehicle width direction, the pair of rear legs (21 RL, 21 RR) is formed so as to be easily bent toward the outside or inside in the vehicle width direction at the middle portion, and when the vehicle collides with the side surface, a load is applied to the bracket (20) by the movement of the seat (11L), and the pair of rear legs (21 RL, 21 RR) are bent, whereby the horizontal state of the inverter (30) is broken.

Description

Support structure for high-voltage component for vehicle Cross Reference to Related Applications The present application claims priority based on japanese patent application No. 2022-070729, filed on 22 th 4 months of 2022, and is incorporated herein by reference in its entirety, including the specification, claims, drawings, and abstract. Technical Field The present disclosure relates to a support structure that supports a flat plate-like high-voltage component between seats aligned in a vehicle width direction. Background An electric vehicle is equipped with a large-capacity battery, and an inverter may be mounted in the vehicle cabin in order to supply electric power from the battery to various electric products and the like. In recent years, as electric vehicles in disaster require power supply to electric appliances in home and the like, converters have become larger. As an example of the arrangement of the large-sized inverter, a structure in which the inverter is arranged between seats arranged in the vehicle width direction is considered (for example, japanese patent application laid-open No. 2005-001655). Disclosure of Invention Here, the inverter is a high-voltage component that receives power from a high-voltage battery, and must be appropriately provided so as not to apply a large load. In the structure disclosed in japanese patent application laid-open No. 2005-001655, in which the inverter is disposed between the seats aligned in the vehicle width direction, the inverter is sandwiched between the seats at the time of a side collision, and a large load generated by the seats may be applied to the inverter. Accordingly, an object of the present disclosure is to provide a support structure for a high-voltage component for a vehicle that can prevent the high-voltage component from being sandwiched between a seat aligned in a vehicle width direction and a seat to apply a large load generated by the seat to the high-voltage component at the time of a side collision of the vehicle. Means for solving the problems The support structure for a vehicle high-voltage component according to the present disclosure is a support structure for a vehicle high-voltage component in a flat plate shape between seats aligned in a vehicle width direction, and is characterized in that the high-voltage component is supported in a horizontal state by a bracket separated upward from a floor in a vehicle interior between the seats, the bracket has a pair of leg portions aligned in the vehicle width direction, the pair of leg portions are formed so as to be easily bent toward an outer side or an inner side in the vehicle width direction at a middle portion, and a load is applied to the bracket by movement of the seats at the time of a side collision of the vehicle, whereby the pair of leg portions are bent, and the horizontal state of the high-voltage component is broken. With the above configuration, at the time of a side collision of the vehicle, one of the pair of legs is further bent due to the load of the seat, and the other is deformed in a linear manner, so that the horizontal state of the high-voltage member is broken. Thus, the high-voltage member is not easily held by the seat and the seat in the horizontal state, and a large load generated by the seat is not easily applied to the high-voltage member by the inclination of the high-voltage member. In the support structure for a high-voltage component for a vehicle according to the present disclosure, the bracket preferably has a bottom plate portion on which the high-voltage component is mounted, and the bottom plate portion has an opening portion exposing a bottom surface of the high-voltage component. With the above configuration, the heat dissipation performance of the high-voltage component can be improved. Effects of the invention According to the support structure of the high-voltage component for a vehicle of the present disclosure, it is possible to prevent the high-voltage component from being sandwiched by the seat aligned in the vehicle width direction and the seat at the time of a side collision of the vehicle, and to apply a large load generated by the seat to the high-voltage component.
