Avoidance-free three-dimensional parking garage

The invention discloses an avoidance-free three-dimensional parking garage. The avoidance-free three-dimensional parking garage comprises a horizontal guide rail which is arranged on the ground and extends along the horizontal direction, a movable chassis which slides along the length extension direction of the horizontal guide rail, an upright post which is distributed along the vertical direction and is rotatably arranged on the movable chassis along the axial lead of the upright post, a vehicle platen component which is arranged on the upright post in a vertical lifting manner, a fixed bed frame which is arranged at the top end of the upright post, and an upper guide rail which is fixedly arranged on the fixed bed frame, wherein the length extension direction of the upper guide rail is parallel to the length extension direction of the horizontal guide rail; the top end of the upright post slides along the length extension direction of the upper guide rail; the avoidance-free three-dimensional parking garage further comprises a rotary driving mechanism used for driving the upright post to rotate along the axial lead of the upright post, a lifting driving mechanism used for driving the vehicle platen component to lift vertically, and a movable driving mechanism used for driving the upright post to slide along the upper guide rail horizontally. The avoidance-free three-dimensional parking garage has the advantages of upper and lower layers of mutually independent parking spaces, convenience for operation and good using stability, and is suitable for new and old drivers.
