[0021] The present invention will be further described below in conjunction with the accompanying drawings:

[0022] like Figures 1 to 5 As shown, a movable vehicle chassis includes two side plates 1 for connecting wheel hubs 2. The two side plates 1 are arc-shaped plates, and the wheel hubs 2 are connected to the outer sides of the side plates 1. A horizontal upper truss 3 is connected between the upper ends of the two side plates 1. The upper truss 3 is formed by welding a number of connecting rods vertically and horizontally. Both ends of the upper truss 3 are provided with hinge supports, and the upper ends of the two side plates 1 are provided with corresponding hinge supports. The upper truss 3 and the side plates 1 are hinged through a pin shaft.

[0023] The lower ends of both side panels 1 are hinged with lower trusses 4, which are arranged opposite to each other and the distal ends of the lower trusses 4 are free ends. The hinged connection between the two lower trusses 4 and the side panels 1 is the same as that of the upper trusses 3. The lower trusses 4 are formed by welding a number of connecting rods in the longitudinal and transverse directions, and the length of the lower trusses 4 is equal to one third of the length of the upper trusses 3. A middle truss 5 is hinged between the distal ends of the two lower trusses 4, which is composed of three connecting rods arranged in a triangle, and a triangular support bar 6 is welded and fixed between the three connecting rods, and the width of the middle truss 5 is slightly less than one third of the width of the upper truss 3, and the height of the middle truss 5 is equal to the height of the side panels 1. The upper end of the support bar 6 is hinged to the upper truss 3 through a pin.

[0024] A locking assembly 7 is also provided between the upper truss 3 and the middle truss 5, and the locking assembly 7 can lock the position of the upper truss 3 and the lower truss 4. The locking assembly 7 includes a guide seat 71, a pull rod 73, a bayonet seat 72 and a spring 74. The guide seat 71 includes two and is fixed to the top of the middle truss 5 at intervals. The bayonet seat 72 is provided on the upper truss 3. Relative through holes are provided on the guide seat 71 and the bayonet seat 72. The pull rod 73 is inserted into the guide seat 71 and the bayonet seat 72. The spring 74 is sleeved on the pull rod 73 at the position between the two guide seats 71.

[0025] A chassis assembly comprises the above-mentioned movable vehicle chassis, and the chassis assembly also comprises a front chassis and a front wheel.

[0026] A vehicle comprises the above-mentioned chassis assembly, and the vehicle also comprises a driving system, a steering system, a braking system and a vehicle roof.

[0027] The structural principle of the present invention is as follows:

[0028] The pull rod 73 can be connected to the pull wire. Under normal conditions, when the pull rod 73 is clamped in the bayonet seat 72, the pull rod 73 plays a limiting role, and the upper truss 3 and the lower truss 4 will not rotate relative to each other. When the pull rod 73 is pulled by the pull wire, the pull rod 73 is separated from the bayonet seat 72, and when the vehicle turns, the wheels can be tilted, effectively reducing the turning radius.

[0029] It should be noted that the above are only some embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
