Furthermore, a locking assembly is further arranged on the vehicle chassis, and the locking assembly can lock the positions of the upper truss and the lower truss.

Further, locking Assembly includes guide holder, pull rod, bayonet socket and spring, the upper end of support bar is located to the guide holder, and on the truss was located to the bayonet socket, all seted up relative through-hole on guide holder and the bayonet socket, the pull rod is worn to locate in guide holder and the bayonet socket, the spring housing is located on the pull rod.

Further, the sum of the lengths of the two lower trusses and the middle truss is equal to the length of the upper truss.

Further, the side plates are arc-shaped in the vertical direction, and the arc lines are sunken towards the outer side of the chassis.

A chassis assembly comprises the movable vehicle chassis, and further comprises a front chassis and front wheels.

A vehicle comprises the chassis assembly, and further comprises a driving system, a steering system, a braking system and a vehicle roof.

The invention has the beneficial effects that: the chassis can be adjusted in a swinging mode along with the running state of a vehicle, and has self-adaptive adjusting capability; when the bicycle moves at medium and high speed, the friction force can be increased, and the turning radius can be effectively reduced; the device adopts four-bar linkage structure, and design benefit can wide application in fields such as tricycle, trailer, has extensive application prospect.

Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

as shown in fig. 1 to 5, a movable vehicle chassis includes two side plates 1 for connecting a hub 2, the two side plates 1 are arc-shaped plates, and the hub 2 is connected to the outer side of the side plates 1. The horizontal upper truss 3 is connected between the upper ends of the two side plates 1, the upper truss 3 is formed by longitudinally and transversely welding a plurality of connecting rods, hinged supports are arranged at the two ends of the upper truss 3, corresponding hinged supports are arranged at the upper ends of the two side plates 1, and the upper truss 3 is hinged with the side plates 1 through pin shafts.

The lower ends of the two side plates 1 are hinged with lower trusses 4, the two lower trusses 4 are arranged oppositely, the far ends of the lower trusses 4 form free ends, and the hinging mode of the two lower trusses 4 and the side plates 1 is the same as that of the upper trusses 3. The lower truss 4 is formed by welding a plurality of connecting rods vertically and horizontally, and the length of the lower truss 4 is equal to one third of that of the upper truss 3. A middle truss 5 is hinged between the far ends of the two lower trusses 4, the middle truss 5 is composed of three connecting rods distributed in a triangular mode, triangular supporting strips 6 are fixed between the three connecting rods in a welded mode, the width of the middle truss 5 is slightly smaller than one third of the width of the upper truss 3, the height of the middle truss 5 is equal to the height of the side plates 1, and the upper end of each supporting strip 6 is hinged with the upper truss 3 through a pin shaft.

And a locking assembly 7 is also arranged between the upper truss 3 and the middle truss 5, and the locking assembly 7 can lock the positions of the upper truss 3 and the lower truss 4. Locking assembly 7 includes guide holder 71, pull rod 73, bayonet socket 72 and spring 74, and guide holder 71 includes two and the interval is fixed in the top of well truss 5, and bayonet socket 72 is located on truss 3, all has seted up relative through-hole on guide holder 71 and the bayonet socket 72, and pull rod 73 wears to locate in guide holder 71 and the bayonet socket 72, and spring 74 cover is located the position that pull rod 73 is located between two guide holders 71.

The structural principle of the invention is as follows:

the pull rod 73 can be connected with a pull wire, and when the pull rod 73 is clamped in the bayonet seat 72 in a normal state, the pull rod 73 plays a limiting role, so that the upper truss 3 and the lower truss 4 cannot rotate relatively. When the pull rod 73 is pulled through the pull wire, the pull rod 73 is separated from the bayonet seat 72, and when the vehicle turns, the wheels can incline, so that the turning radius is effectively reduced.

It should be noted that the above are only some embodiments of the present invention, and it should be noted that, for those skilled in the art, many modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
