Abstract

An embodiment structure for reinforcing a deck of a vehicle includes chassis frames positioned on both side surfaces of a lower end of the deck of the vehicle, a wheelhouse assembly positioned on the chassis frame and defining a side surface of the deck, and a reinforcement structure positioned at an end of the wheelhouse assembly at a position where a rear gate is positioned at a rear end of the deck.

Claims (47)

1 . A structure for reinforcing a deck of a vehicle, the structure comprising:

chassis frames positioned on both side surfaces of a lower end of the deck of the vehicle;

a wheelhouse assembly positioned on the chassis frames and defining a side surface of the deck;

a reinforcement structure positioned at an end of the wheelhouse assembly at a position where a rear gate is positioned at a rear end of the deck; and

chassis mounting parts positioned on the wheelhouse assembly in contact with the chassis frames, wherein the chassis mounting parts, the reinforcement structure, and the wheelhouse assembly are integrally configured.

2 . The structure of claim 1 , wherein the reinforcement structure comprises a gradation part in which a plurality of rigid ribs are positioned in a height direction.

3 . The structure of claim 2 , wherein the reinforcement structure is fastened to a side member positioned at the rear end of the deck.

4 . The structure of claim 3 , wherein the plurality of rigid ribs are positioned at equal intervals along the height direction based on the side member.

5 . The structure of claim 4 , wherein the reinforcement structure further comprises:

a rigid part provided at an end of the gradation part;

a striker part positioned on the rigid part and fastened to a locker of the rear gate; and

a hinge part positioned between the rear gate and the rigid part to rotatably open and close the rear gate.

6 . The structure of claim 5 , wherein the equal intervals between the plurality of rigid ribs are smaller than intervals of mounting holes such that the striker part is fastened to the reinforcement structure or are smaller than a mounting hole where the hinge part is positioned.

7 . The structure of claim 5 , further comprising a rear hook part positioned adjacent to one rigid rib of the plurality of rigid ribs.

8 . The structure of claim 7 , wherein the one rigid rib and one end of the rigid part have a ‘P’-shaped cross section.

9 . The structure of claim 3 , wherein the plurality of rigid ribs have an equal angle along the height direction based on the side member.

10 . The structure of claim 1 , further comprising vertical ribs extending in a height direction of the chassis mounting parts of the wheelhouse assembly.

11 . The structure of claim 10 , further comprising a side hook part at a position corresponding to one of the vertical ribs.

12 . A structure for reinforcing a deck of a vehicle, the structure comprising:

chassis frames positioned on both side surfaces of a lower end of the deck of the vehicle;

a wheelhouse assembly positioned on the chassis frames and shaped according to a curvature of wheels of the vehicle;

a side member positioned at a rear end of the deck;

a reinforcement structure positioned at an end of the wheelhouse assembly at a position where a rear gate is positioned at the rear end of the deck;

wherein the reinforcement structure comprises a gradation part in which a plurality of rigid ribs are positioned at equal intervals in a height direction of the side member;

chassis mounting parts positioned on the wheelhouse assembly in contact with the chassis frames; and

wherein the chassis mounting parts, the reinforcement structure, and the wheelhouse assembly are integrally configured.

13 . The structure of claim 12 , wherein the reinforcement structure further comprises:

a rigid part provided at an end of the gradation part;

a striker part positioned on the rigid part and fastened to a locker of the rear gate; and

a hinge part positioned between the rear gate and the rigid part to rotatably open and close the rear gate.

14 . The structure of claim 13 , wherein the equal intervals of the plurality of rigid ribs are smaller than intervals of mounting holes such that the striker part is fastened to the reinforcement structure or are smaller than intervals of mounting holes where the hinge part is positioned.

15 . The structure of claim 12 , wherein the plurality of rigid ribs have an equal angle along the height direction based on the side member.

16 . A structure for reinforcing a deck of a vehicle, the structure comprising:

chassis frames positioned on both side surfaces of a lower end of the deck of the vehicle;

a wheelhouse assembly positioned on the chassis frames and shaped according to a curvature of wheels of the vehicle;

a side member positioned at a rear end of the deck;

a reinforcement structure positioned at an end of the wheelhouse assembly at a position where a rear gate is positioned at the rear end of the deck, wherein the reinforcement structure comprises a gradation part in which a plurality of rigid ribs are positioned at equal intervals in a height direction of the side member; and

a rear hook part positioned adjacent to one rigid rib of the plurality of rigid ribs.

17 . The structure of claim 16 , wherein:

the reinforcement structure further comprises:

a rigid part provided at an end of the gradation part;

a striker part positioned on the rigid part and fastened to a locker of the rear gate; and

a hinge part positioned between the rear gate and the rigid part to rotatably open and close the rear gate; and

the one rigid rib and one end of the rigid part have a ‘P’-shaped cross section.

18 . The structure of claim 12 , further comprising vertical ribs extending in a height direction of the chassis mounting parts of the wheelhouse assembly.

19 . The structure of claim 18 , further comprising a side hook part at a position corresponding to one of the vertical ribs.

20 . The structure of claim 12 , wherein the wheelhouse assembly and the reinforcement structure are integrally cast.
