Structure for mounting batteries onto electric vehicles

1. A structure for mounting a battery to an electric vehicle, comprising:

a body member forming a body of the electric vehicle;

a battery case containing the battery, said battery case having a front-end wall extending substantially in a vertical direction of the electric vehicle;

a supporting member, which is connected to said body member, fixed to a bottom of said battery case; and

a clash-proof block connecting between the battery case and the body member, wherein

said body member includes,

a pair of first body members extending in a longitudinal direction of said electric vehicle, and

a second body member which extends in the transversal direction of the electric vehicle and provided across said pair of first body members, forming said body of said electric vehicle,

said battery case is disposed between said pair of first body members and the rear of said second body member while forming a gap between said battery case and the rear of said second body member, and

said clash-proof block includes a first clash-proof block attached to and extending from said front-end wall and connecting said front-end wall of said battery case to said second body member, said first clash-proof block maintaining the gap and preventing said battery case from colliding with said second body member,

wherein said supporting member includes,

a plurality of first supporting members which extend in the transversal direction of said electric vehicle and connects between said pair of first body members, and

a second supporting member which extends in the longitudinal direction of the electric vehicle, and connects to only one of said first supporting members, which is disposed at the front row, to said second body member, and

said supporting member and said clash-proof block are made of metal.

2. The structure for mounting the battery to the electric vehicle according to claim 1 wherein

said first supporting members, being plate-shaped members, which are provided across said pair of first body members, supporting the bottom of said battery case.

3. The structure for mounting the battery to the electric vehicle according to claim 2 wherein

said battery case is disposed between said pair of first body members and the rear of said second body member while forming a gap between said battery case and at least one of said pair of first body members, and

said clash-proof block includes a second clash-proof block connecting a side surface of said battery case to said one of the pair of first body members, said second clash-proof block maintains the gap between said battery case and said one of the pair of first body members and prevents said battery case from colliding with said second body member.

4. The structure for mounting the battery to the electric vehicle according to claim 3 wherein

said supporting member and said clash-proof block are made from metal, and

said battery case is made from resin.

5. The structure for mounting the battery to the electric vehicle according to claim 2 wherein

said supporting member and said clash-proof block are made from metal, and

said battery case is made from resin.

6. The structure for mounting the battery to the electric vehicle according to claim 1 wherein

said clash-proof block includes a second clash-proof block connecting between said battery case and one of said pair of first body members.

7. The structure for mounting the battery to the electric vehicle according to claim 6 wherein

said supporting member and said clash-proof block are made from metal, and

said battery case is made from resin.

8. The structure for mounting the battery to the electric vehicle according to claim 1 wherein

said supporting member and said clash-proof block are made from metal, and

said battery case is made from resin.

9. The structure for mounting the battery to the electric vehicle according to claim 1 wherein

said supporting member and said clash-proof block are made from iron.

10. A structure for mounting a battery to an electric vehicle, comprising:

a battery case containing the battery, said battery case having a front-end wall extending substantially in a vertical direction of the electric vehicle;

a first supporting member, which extends in a transversal direction of the electric vehicle, for supporting said battery case on a pair of first body members extending in the longitudinal direction of the electric vehicle;

a second supporting member, which extends in a front direction of the electric vehicle from said first supporting member, for supporting said battery case on a second body member, said second body member extending in a transversal direction of the electric vehicle and connecting said pair of first body members, and forming a gap between said battery case and said second body member; and

a first clash-proof block attached to and extending from said front-end wall and connecting said front-end wall of said battery case to said second body member, said first clash-proof block maintaining the gap and preventing said battery case from colliding with said second body member.

11. The structure for mounting the battery to the electric vehicle according to claim 10 wherein

said first supporting member and said second supporting member are fixed to a bottom of said battery case.

12. The structure for mounting the battery to the electric vehicle according to claim 10 , wherein

said first supporting member supports said battery case on said pair of first body members while forming a gap between said battery case and at least one of said pair of first body members,

the structure further comprising:

a second clash-proof block connecting a side surface of said battery case to said one of the pair of first body members, said second clash-proof block maintains the gap between said battery case and said one of the pair of first body members and preventing said battery case from colliding with said one of the pair of first body members.

13. The structure for mounting the battery to the electric vehicle according to claim 12 wherein

said first supporting member, said second supporting member, said first clash-proof block, and said second clash-proof block are made from metal, and

said battery case is made from resin.
