Joint member for coupling chassis frame and variable chassis module of vehicle using the same

A variable chassis module of a vehicle, in which a plurality of frames coupled to each other form a chassis module, the variable chassis module comprising:

• a main frame which has a substantially rectangular shape;
• joint frames each extending from edges of the main frame outward in a lateral direction which is a width direction of the chassis module;
• and
• joint members each coupled to the joint frames,
• wherein each of the joint members includes a first insertion groove which is formed in plural on one surface facing the joint frame so that an end portion of the joint frame is inserted thereinto, and the plurality of first insertion grooves are formed in a longitudinal direction of the chassis module so that a length of the chassis module is changed according to a position at which the joint frame is inserted.

A joint member for coupling a chassis frame, which couples frames composing a chassis, the joint member comprising:

• a main body which has a block shape;
• a first insertion groove into which one end portion of a horizontal frame, which is a width-directional frame of the chassis, is inserted and which is formed in plural on a first side surface of the main body;
• and
• a second insertion groove into which one end portion of a vertical frame, which is a longitudinal direction of the chassis, is inserted and which is formed on a second side surface of the main body, the second side surface being adjacent to the first side surface,
• wherein the plurality of first insertion grooves are formed in a longitudinal direction of the chassis so that a length of the chassis is changed according to a position at which the horizontal frame is inserted.

A variable chassis module of a vehicle, in which a plurality of frames coupled to each other form a chassis module, the variable chassis module comprising:

• a pair of horizontal frames disposed to be spaced apart from each other in a vertical direction;
• a pair of vertical frames each disposed on the left and right of the horizontal frame;
• and
• joint members each connected to edges of a rectangular shape so that the horizontal frames and the vertical frames are coupled to each other in the rectangular shape,
• wherein each of the joint members includes a first insertion groove formed in plural on a first side surface facing the horizontal frame so that one end portion of the horizontal frame is inserted thereinto, and a second insertion groove formed on a second side surface facing the vertical frame so that one end portion of the vertical frame is inserted thereinto,
• wherein the plurality of first insertion grooves are formed in a longitudinal direction of the chassis module so that a length of the chassis module is changed according to a position at which the horizontal frame is inserted.
