Abstract
An inverter buffer structure for a vehicle is provided so that even when a head-on collision occurs, no damage is caused to the inverter case and its internal contents. In one embodiment an inverter buffer structure for a vehicle is disposed with an inverter in an engine compartment and is provided with buffer member between a surface of the inverter and a radiator core support that constitutes a portion of a frame of the vehicle to reduce an incoming force to the vehicle in the event of a collision.
Claims8
An inverter buffer structure for a vehicle, comprising:
- an inverter disposed in a compartment of the vehicle;
- a radiator core support that constitutes a frame portion of the vehicle;
- and
- a buffer member that is disposed directly adjacent to the inverter and is disposed directly adjacent to the radiator core support, such that the buffer member is disposed between the inverter and the radiator core support, wherein deflection of the radiator core support in a front-to-rear direction of the vehicle during a head-on collision of the vehicle causes engagement of the buffer member with the radiator core support and the inverter such that the buffer member reduces the amount of an incoming force that is applied to the inverter during the collision, wherein the buffer member is supported by a bracket provided on the inverter itself, and an open space is provided between the buffer member and the inverter to allow movement of the buffer member with respect to the inverter in the front-to-rear direction of the vehicle during the collision.

A method of protecting an inverter of a vehicle during a head-on collision of the vehicle, comprising:
- disposing a buffer member directly adjacent to the inverter and a radiator core support that constitutes a frame portion of the vehicle by connecting the buffer member to the inverter using a bracket such that the buffer member is disposed between the inverter and the radiator core support, and restraining a lower portion of the buffer member in a front-to-rear direction of the vehicle using a structure having lower rigidity that the bracket such that the structure deforms more readily than the bracket during the collision, wherein deflection of the radiator core support in a front-to-rear direction of the vehicle during a head-on collision of the vehicle causes engagement of the buffer member with the radiator core support and the inverter such that the buffer member reduces the amount of an incoming force that is applied to the inverter during the collision.
