Chassis of automatic guided vehicle and automatic guided vehicle
Disclosed are a chassis of an automated guided vehicle and an automated guided vehicle. The chassis includes a front frame ( 1 ) and a rear frame ( 2 ) that are engaged with each other in a hinged joint manner, so as to allow a relative folding between the rear frame ( 2 ) and the front frame ( 1 ). The relative folding enables the driving wheels and the driven wheels to touch the ground on a sunken road at the same time to prevent that only the driven wheels ( 10 ) touch the ground while the driving wheels ( 9 ) slip, and increases the approach angle of the chassis on a convex road to prevent the front end of the chassis from touching any obstacle, which improve the safety of the vehicle. Moreover, the damping device ( 3 ) restricts the folding angle of the front frame ( 1 ) and the rear frame ( 2 ) to prevent that the relative folding angle of the front frame ( 1 ) and the rear frame ( 2 ) is too large to realize the transport function, and damps the folding angle for reducing vibration.

a front frame ( 1 );
a rear frame ( 2 ), wherein the rear frame ( 2 ) engages with the front frame ( 1 ) in a hinge joint manner to allow relative folding between the rear frame ( 2 ) and the front frame ( 1 ); and
a damping device ( 3 ) that is arranged between the front frame ( 1 ) and the rear frame ( 2 ) for generating a damping restraining force against the relative folding;
wherein an overlap area is provided in a position at which the front frame ( 1 ) engages with the rear frame ( 2 ), and a folding space (D) is reserved in the overlap area for realizing the relative folding; and
wherein the damping device ( 3 ) is located in the overlap area.

a limiting boss ( 301 b ), that is located between the damping mounting arm ( 8 ) and the damping mounting boss ( 7 ), and provides a placement plane ( 301 c ) for the second cushion ( 303 b ); and
a connecting portion ( 301 d ), that penetrates the damping mounting arm ( 8 ), and is fixed on the damping mounting arm ( 8 ) by means of the backing plate ( 302 );
wherein, the connecting portion ( 301 d ) is provided with a threaded blind hole ( 301 e ) that extends in an axial direction of the threaded blind hole ( 301 e ) and is used for mounting a locking screw ( 304 ).
7. The chassis of an automated guided vehicle according to claim 1 , wherein a circular hollow (A) is formed at the position at which the front frame ( 1 ) engages with the rear frame ( 2 ).
