Abstract

A structure for mounting a battery onto an electric vehicle comprises: a body member forming a body of the electric vehicle; a battery case containing a battery; a supporting member, which is projected outward from the battery case and is disposed under the body member, fixed to a bottom of said battery case; and a clash-proof block connecting between the battery case and the body member.

Claims

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;

a supporting member, which is projected outward from said battery case and is disposed under the body member, fixed to a bottom of said battery case;

a metal frame which is embedded in a wall of said battery case, said metal frame having a first fixing member attached to and extending from said metal frame, said first fixing member being a nut that is welded to said metal frame and is embedded in the wall of said battery case together with the metal frame; and

at least one clash-proof block directly attached to said wall of said battery case and said supporting member, said at least one clash-proof block being attached to said wall by a second fixing member that engages said first fixing member,

wherein said body member includes,

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

a second body member, connected to said pair of first body members, extending in a transversal direction of the electric vehicle,

said battery case is disposed between said pair of first body members and rear of said second body member, and

wherein said at least one clash-proof block includes,

a first clash-proof block connected to said battery case and said second body member, and

a second clash-proof block connected to said wall of said battery case having the metal frame embedded therein and one of said pair of first body members.

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

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

said battery case is made from resin.

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

said supporting member includes at least one first supporting member that extends toward said pair of first body members.

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

said supporting member includes a second supporting member that extends toward said second body member.

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

said supporting member and said at least one 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 3 wherein

said at least one first supporting member includes a plurality of first supporting members which connect to said pair of first body members,

said supporting member further includes 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 a front row, to said second body member, and

said supporting member and said at least one clash-proof block are made from metal.

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

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

8. The structure for mounting the battery to the electric vehicle according to claim 1, wherein said second fixing member is a bolt engaged with said nut.

9. The structure for mounting the battery to the electric vehicle according to claim 1, wherein said first fixing member comprises a plurality of nuts welded to said metal frame and embedded in the wall of said battery case together with the metal frame, and said second fixing member comprises a plurality of bolts engaged with said nuts.

10. 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 a battery;

a supporting member, which is projected outward from said battery case and is disposed under the body member, fixed to a bottom of said battery case;

a metal frame which is embedded in a wall of said battery case, said metal frame having a first fixing member attached to and extending from said metal frame, said first fixing member being a nut that is welded to said metal frame and is embedded in the wall of said battery case together with the metal frame; and

a clash-proof block directly attached to said wall of said battery case and spaced apart from said supporting member, said clash-proof block being attached to said wall by a second fixing member that engages said first fixing member,

wherein said supporting member and said clash-proof block are attached to said body member, and

said clash-proof block is connected to said body member and said wall of said battery case having the metal frame embedded therein.

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

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

said battery case is made from resin.

12. The structure for mounting the battery to the electric vehicle according to claim 10, wherein said second fixing member is a bolt engaged with said nut.

13. The structure for mounting the battery to the electric vehicle according to claim 10, wherein said first fixing member comprises a plurality of nuts welded to said metal frame and embedded in the wall of said battery case together with the metal frame, and said second fixing member comprises a plurality of bolts engaged with said nuts.
