Abstract
A protector structure for an underfloor component includes an underfloor component that is a high-voltage component or a fuel tank disposed under a floor of a vehicle, a boarding and alighting step disposed further laterally outward with respect to the underfloor component, and a protection member disposed between the underfloor component and the boarding and alighting step. The protection member includes a contact wall that laterally faces the boarding and alighting step and that is inclined laterally inward as the contact wall extends downward.
Claims5
An underfloor component protector structure comprising:
- an underfloor component disposed under a floor of a vehicle, the underfloor component being a high-voltage component or a fuel tank;
- a boarding and alighting step disposed further laterally outward with respect to the underfloor component;
- and
- a protection member disposed between the underfloor component and the boarding and alighting step,
- wherein the protection member comprises a contact wall laterally facing the boarding and alighting step, the contact wall being inclined laterally inward as the contact wall extends downward;
- wherein the boarding and alighting step comprises:
- a first attachment portion fastened to part of a vehicle body;
- and
- a second attachment portion fastened to part of the vehicle body at a location further laterally inward with respect to the first attachment portion;
- and
- wherein a downward force applied to a laterally inward end of the boarding and alighting step unfastens the second attachment portion from the vehicle body more preferentially than unfastening of the first attachment portion from the vehicle body.
An underfloor component protector structure comprising:
- an underfloor component disposed under a floor of a vehicle, the underfloor component being a high-voltage component or a fuel tank;
- a boarding and alighting step disposed further laterally outward with respect to the underfloor component;
- a protection member disposed between the underfloor component and the boarding and alighting step;
- an underfloor frame that is a vehicle body frame extending along a vehicle length under the floor of the vehicle between the contact wall and the underfloor component;
- and
- a component support member configured to support the underfloor component and attached to a bottom face of the underfloor frame,
- wherein the protection member comprises a contact wall laterally facing the boarding and alighting step, the contact wall being inclined laterally inward as the contact wall extends downward,
- wherein the protection member further comprises:
- an upper reinforcing member disposed between the contact wall and the underfloor frame, the upper reinforcing member configured to transmit a laterally inward load to the underfloor frame, the laterally inward load to be received from the contact wall;
- a lower reinforcing member disposed between the contact wall and the component support member at a location below the upper reinforcing member, the lower reinforcing member configured to transmit a laterally inward load to the component support member, the laterally inward load to be received from the contact wall;
- wherein the protection member has a bottom face including two or more cut portions at a laterally inward edge of the bottom face,
- wherein the component support member has laterally outward edges that extend into the cut portions, respectively, and
- wherein peripheral edges of the cut portions and the laterally outward edges of the component support member are laterally apart from each other.
