Abstract

A vehicle chassis including a vehicle frame defining an inner space and being operable to switch between a first expanded state and a collapsed state, and a loading device mounted to the inner space and removably connected to the vehicle frame. The loading device defines a first loading surface when the vehicle frame is in the first expanded state, and the loading device defines a second loading surface that is smaller than the first loading surface when the vehicle frame is in the collapsed state.

First claim

What is claimed is:

wherein, when said vehicle frame ( 10 ) is in the collapsed state, said second loading assembly ( 3 ) is separated from said first loading assembly ( 2 ), and said first loading assembly ( 2 ) is in an assembled state and defines said second loading surface ( 202 ).

2. The vehicle chassis ( 100 ) as claimed in claim 1 , wherein:
said first loading assembly ( 2 ) includes a plurality of first loading boxes ( 21 ) removably connected to said vehicle frame ( 10 ), and a plurality of first battery modules ( 23 ) removably and respectively disposed in said first loading boxes ( 21 ), each of said first loading boxes ( 21 ) being permitted to be removably coupled to adjacent ones of said first loading boxes ( 21 );
when said first loading assembly ( 2 ) is in the separated state, said first loading boxes ( 21 ) are spaced apart from each other to define said mounting space ( 25 ) thereamong; and
when said first loading assembly ( 2 ) is in the assembled state, said first loading boxes ( 21 ) are coupled to each other to cooperatively define said second loading surface ( 202 ).

3. The vehicle chassis ( 100 ) as claimed in claim 2 , wherein:
said vehicle frame ( 10 ) is permitted to be telescopic in at least a front-rear direction (X);
said vehicle frame ( 10 ) is formed with at least one lateral opening ( 16 ) that is registered with said mounting space ( 25 );
said second loading assembly ( 3 ) includes at least one second loading box ( 31 ) and at least one second battery module ( 33 ) removably disposed in said at least one second loading box ( 31 ), said at least one second loading box ( 31 ) being permitted to be removably coupled between corresponding two of said first loading boxes ( 21 ); and
when said vehicle frame ( 10 ) is in the first expanded state, said second loading box ( 31 ) is permitted to be uncoupled from said first loading boxes ( 21 ) in a lateral direction (Y) perpendicular to the front-rear direction (X) through said lateral opening ( 16 ).

4. The vehicle chassis ( 100 ) as claimed in claim 3 , wherein:
said vehicle frame ( 10 ) is formed with two of said lateral openings ( 16 ) respectively at two opposite sides thereof, said lateral openings ( 16 ) being spaced apart in the lateral direction (Y);
said second loading assembly ( 3 ) includes two of said second loading boxes ( 31 ) and two of said second battery modules ( 33 ) removably and respectively disposed in said second loading boxes ( 31 ); and
when said vehicle frame ( 10 ) is in the first expanded state, each of said second loading boxes ( 31 ) is permitted to be respectively uncoupled from corresponding two of said first loading boxes ( 21 ) through a respective one of said lateral openings ( 16 ).

5. The vehicle chassis ( 100 ) as claimed in claim 4 , wherein:
said vehicle frame ( 10 ) is telescopic in the front-rear direction (X) and the lateral direction (Y), such that said vehicle frame ( 10 ) is operable to switch between the first expanded state and the collapsed state;
said vehicle frame ( 10 ) is substantially rectangular, includes four casing members ( 11 ) respectively disposed at four corners of said vehicle frame ( 10 ), and is further formed with an end opening ( 17 ) that is permitted to be registered to said mounting space ( 25 );
said first loading assembly ( 2 ) includes four of said first loading boxes ( 21 ) removably and respectively connected to said casing members ( 11 );
said second loading assembly ( 3 ) further includes a third loading box ( 34 ) and at least one third battery module ( 36 ) removably disposed in said third loading box ( 34 ), said third loading box ( 34 ) being permitted to be removably coupled among said first loading boxes ( 21 ) and said second loading boxes ( 31 ); and
when said vehicle frame ( 10 ) is in the first expanded state, said first, second and third loading boxes ( 21 , 31 , 34 ) cooperatively define said first loading surface ( 201 ), and said third loading box ( 34 ) is permitted to be uncoupled from said first and second loading boxes ( 21 , 31 ) in the front-rear direction (X) through said end opening ( 17 ).

6. The vehicle chassis ( 100 ) as claimed in claim 5 , wherein:
said first, second and third battery modules ( 23 , 33 , 36 ) are electrically connected to each other in parallel when said vehicle frame ( 10 ) is in the first expanded state; and
