Vehicle body structure and onboard battery for vehicle
View Patent ↗Some vehicles are equipped with an onboard battery. The onboard battery includes a holding frame having a frame-shaped part, a housing case that is held by the holding frame, being inserted into the frame-shaped part, and battery modules housed in the housing case. For such a vehicle with the onboard battery, the vehicle body structure includes a displacement restricting part and a disposition depression. The displacement restricting part restricts an upward displacement of the onboard battery in a collision from behind is formed at a position facing a front end portion of the holding frame. The disposition depression is formed in a floor panel and the onboard battery is disposed to be at least partly inserted into the disposition depression.

a disposition depression in a floor panel, wherein the battery is at least partly inserted in the disposition depression.
2. The vehicle body structure according to claim 1 , wherein the displacement restricting part is on a seat hinge bracket, wherein the seat hinge bracket is configured to support a turning shaft of rear seats.
3. The vehicle body structure according to claim 2 , wherein
a reinforcing member is mounted on an inner surface of a front end portion of the housing case, and
a lower end portion of the displacement restricting part is at a same height as a height of the reinforcing member.
4. The vehicle body structure according to claim 2 , wherein the seat hinge bracket is fixed to a cross-member with the floor panel, wherein the floor panel is between the seat hinge bracket and the cross-member.
5. The vehicle body structure according to claim 4 , wherein
a reinforcing member is mounted on an inner surface of a front end portion of the housing case, and
a lower end portion of the displacement restricting part is at a same height as a height of the reinforcing member.
6. The vehicle body structure according to claim 1 ,
wherein a seat hinge bracket is fixed to a cross-member with the floor panel, wherein the floor panel is between the seat hinge bracket and the cross-member, and
wherein the seat hinge bracket is configured to support a turning shaft of rear seats.
7. The vehicle body structure according to claim 6 , wherein
a reinforcing member is mounted on an inner surface of a front end portion of the housing case, and
a lower end portion of the displacement restricting part is at a same height as a height of the reinforcing member.
8. The vehicle body structure according to claim 1 , wherein
a reinforcing member is mounted on an inner surface of a front end portion of the housing case, and
a lower end portion of the displacement restricting part is at a same height as a height of the reinforcing member.
9. The vehicle body structure according to claim 1 , wherein a lower surface of a mounted part of the housing case is in contact with an upper surface of the frame-shaped part of the holding frame.
10. A battery for a vehicle including one or more battery modules, comprising:
a holding frame including a frame-shaped part;
a housing case configured to be inserted into the frame-shaped part, wherein the one or more battery modules are housed in the housing case,
wherein an outer peripheral edge part of the housing case is fixed to the frame-shaped part with a fixing member to fix the housing case to the holding frame,
wherein the battery is at least partly inserted into a disposition depression in a floor panel of the vehicle; and
a front end portion of the holding frame is at a position that faces a displacement restricting part of the vehicle, wherein the displacement restricting part restricts an upward displacement of the battery in a collision from behind the vehicle, and wherein an upper end portion of the displacement restricting part comprises a projecting part that projects rearward.
11. The battery according to claim 10 , wherein
a reinforcing member is mounted on an inner surface of a front end portion of the housing case, and
the reinforcing member is at a same height as a height of a lower end portion of the displacement restricting part.
12. A vehicle body structure for a vehicle equipped with a battery including one or more battery modules, the vehicle body structure comprising:
a holding frame that includes a frame-shaped part;
a housing case configured to be inserted into the frame-shaped part,
wherein the at least one battery module is housed in the housing case,
wherein an outer peripheral edge part of the housing case is fixed to the frame-shaped part with a fixing member to fix the housing case to the holding frame, and
wherein a lower surface of a mounted part of the housing case is in contact with an upper surface of the frame-shaped part of the holding frame;
