Patent ID: 7497618

Claim:
A mobile vehicle inspection system comprising: a moving device; a driving device for driving the moving device to move during scanning inspection; a radiation source disposed on the moving device for emitting a ray; a rotary table pivotally disposed on the moving device; an upright post installed on the rotary table at a lower end of the upright post so as to be rotatable with the rotary table; a transverse detector beam with a first array of detectors, the transverse detector beam having an end connected with an upper end of the upright post; an upright detector beam with a second array of detectors, the upright detector beam having an upper end connected with the other end of the transverse detector beam, and extending downwards from the other end of the transverse detector beam so that the upright post, the transverse detector beams, and the upright detector beam constitute a frame of a substantially inverted “U” shape, wherein the transverse detector beam and the upright detector beam can swing, by pivoting the upright post, between a retracted position in which they are retracted to the moving device and a projected position in which they are projected from the moving device, and wherein when the transverse detector beam and the upright detector beam are located in the projected position, a ray emitted from the radiation source is located immediately opposite the first array of detectors and the second array of detectors so as to inspect a vehicle to be inspected which passes through the frame, and when the transverse detector beam and the upright detector beam are located in the retracted position, the transverse detector beam and the upright detector beam remain in the substantially inverted “U” shape.
