Abstract

The present disclosure provides a battery load support structure of a fuselage, the battery load support structure including a battery mount support formed in a longitudinal direction of a floor frame of the fuselage, a battery unit inputted into an opened lower side of the floor frame and fastened to the battery mount support, and a joint unit configured to support the battery mount support and connected to a plurality of framework members that constitutes the floor frame.

Claims (37)

1. A structure, comprising:

a battery mount support coupled to a floor frame of a fuselage;

a battery unit inputted into an opened lower side of the floor frame and fastened to the battery mount support; and

a joint unit configured to support the battery mount support and connected to a plurality of framework members that constitutes the floor frame,

wherein the joint unit comprises:

a front joint mounted at a position at which the battery mount support faces a front bulkhead that constitutes at least one of the plurality of framework members;

a first center joint mounted on the battery mount support and configured to accommodate therein a first center bulkhead that constitutes at least one of the plurality of framework members;

a second center joint formed as a second center bulkhead that constitutes at least one of the plurality of framework members, wherein the second center bulkhead is connected to a connection frame, and wherein the connection frame is configured to support the battery mount support and a passenger space of the fuselage; and

a rear joint coupled to a rear bulkhead that constitutes at least one of the plurality of framework members,

wherein the front joint is provided as a skid mounting bracket for fastening a front skid member mounted on the opened lower side of the floor frame, and

wherein the battery mount support has a coupling guide extending to correspond to a shape of a coupling flange of the second center joint.

2. The structure according to claim 1 , wherein the second center joint is formed in a hemispherical shape corresponding to a shape of a lower portion of the fuselage and the connection frame is flange-coupled to the second center bulkhead.

3. The structure according to claim 1 , wherein the battery unit comprises:

a battery configured to supply electric power for operating the fuselage; and

a battery support configured to support two opposite sides of the battery, wherein the battery support is coupled to the battery mount support.

4. The structure according to claim 3 , wherein the battery support is fixed to the battery and to the battery mount support by a nut and a bolt, and wherein the bolt penetrates the battery mount support and the battery support.

5. The structure according to claim 1 , further comprising:

a fuselage lower panel configured to constitute a bottom surface of the fuselage by being coupled to a side panel of the fuselage in a state in which the battery unit is coupled to the battery mount support.

6. A vehicle, comprising:

a body;

a battery mount support coupled to a floor frame of the body;

a battery unit inputted into an opened lower side of the floor frame and fastened to the battery mount support; and

a joint unit configured to support the battery mount support and connected to a plurality of framework members that constitutes the floor frame, wherein the joint unit comprises:

a front joint mounted at a position at which the battery mount support faces a front bulkhead that constitutes at least one of the plurality of framework members; and

a rear joint coupled to a rear bulkhead that constitutes at least one of the plurality of framework members,

wherein the front joint is provided as a skid mounting bracket for fastening a front skid member mounted on the opened lower side of the floor frame, and

wherein the battery mount support has a coupling guide extending to correspond to a shape of a coupling flange of a center joint of the joint unit.

7. The vehicle according to claim 6 , wherein the joint unit further comprises:

a first center joint mounted on the battery mount support and configured to accommodate therein a first center bulkhead that constitutes at least one of the plurality of framework members; and

the center joint of the joint unit, wherein the center joint of the joint unit is a second center joint formed as a second center bulkhead that constitutes at least one of the plurality of framework members, wherein the second center bulkhead is connected to a connection frame, and wherein the connection frame is configured to support the battery mount support and a passenger space of the body.

8. The vehicle according to claim 7 , wherein the second center joint is formed in a hemispherical shape corresponding to a shape of a lower portion of the body and the connection frame is flange-coupled to the second center bulkhead.

9. The vehicle according to claim 6 , wherein the battery unit comprises:

a battery configured to supply electric power for operating the body; and

a battery support configured to support two opposite sides of the battery, wherein the battery support is coupled to the battery mount support.

10. The vehicle according to claim 9 , wherein the battery support is fixed to the battery and to the battery mount support by a nut and a bolt, and wherein the bolt penetrates the battery mount support and the battery support.

11. The vehicle according to claim 6 , further comprising:

a lower panel configured to constitute a bottom surface of the body by being coupled to a side panel of the body in a state in which the battery unit is coupled to the battery mount support.
