Battery fixing structure
A vehicle includes: a pair of coupling brackets which face side surfaces of the battery and are fixed to inner wall surfaces of the pair of side frames, a support bracket which is coupled to inclined portions of the coupling brackets by fastening members, pin members which protrude from the inclined portions, a positioning hole with which the pin members are positioned, and a guide hole that communicates with the positioning hole and has a larger diameter than the positioning hole.
1. A battery fixing structure for fixing a battery between a pair of side frames of a vehicle body, the battery fixing structure comprising:
a pair of first brackets facing side surfaces of the battery and fixed to an inner wall surface of each of the pair of side frames;
a second bracket which supports a bottom surface of the battery and is coupled, by a fastening member, to an inclined portion inclined with respect to a vertical direction of the pair of first brackets;
a pin member protruding from the inclined portion of the first brackets;
a positioning hole provided in the second bracket and in which the pin member is positioned; and
a guide hole that communicates with the positioning hole in the second bracket and has a larger diameter than the positioning hole.
2. The battery fixing structure according to claim 1 , wherein the guide hole is an elongated hole whose longitudinal direction extends along the vertical direction.
3. The battery fixing structure according to claim 1 , wherein
the inclined portion includes an inclined surface inclined such that a distal end of the first
brackets faces the center in a vehicle width direction of the vehicle body, and the pin member protrudes in the normal direction of the inclined surface.
4. The battery fixing structure according to claim 1 , wherein
the second bracket is coupled to the inclined portion by a plurality of fastening members arranged at predetermined intervals, and
the positioning hole and the guide hole are positioned between the plurality of fastening members.
5. The battery fixing structure according to claim 1 , wherein
an outer circumferential surface of the pin member includes a groove along the circumferential direction, and
a width of the groove is greater than a thickness of the second bracket.
6. The battery fixing structure according to claim 1 , wherein
an outer circumferential surface of the pin member includes a groove along the circumferential direction, and
the groove is formed at a position where the groove of the pin can be engaged with an edge of the guide hole.
7. The battery fixing structure according to claim 1 , wherein
the second bracket includes:
a support portion that supports the bottom surface of the battery; and
a bent portion bent from an end portion of the support portion and coupled to the inclined portion.
8. The battery fixing structure according to claim 7 , wherein
the bent portion is in contact with an inclined surface of the inclined portion, and
the pin member protrudes in the normal direction from the inclined surface.
9. The battery fixing structure according to claim 1 , wherein the guide hole is positioned above the positioning hole in the vertical direction.
10. The battery fixing structure according to claim 1 , wherein the pin member is positioned by the positioning hole after being inserted into the guide hole when the battery is fixed to the side frames in an inverted state.
