Three-dimensional parking system

A three-dimensional parking system, comprising:

• a supporting upright column (1), an annular railway (2), a parking platform (3), a platform bracket (4), a transportation module (8), a vertical power system (5), a rotating power system (6), and a platform interlocking system, wherein
• a longitudinal channel (7) extending in an axial direction of the supporting upright column (1) is arranged on the supporting upright column (1), the transportation module (8) is arranged in the longitudinal channel (7), and the vertical power system (5) drives the transportation module (8) to reciprocate up and down along the longitudinal channel (7);
• the annular railway (2) is arranged around a periphery of the supporting upright column (1), at least one layer of the annular railway (2) is arranged in the axial direction of the supporting upright column (1), a notch (9) is formed in a position of each layer of the annular railway (2) penetrated by the longitudinal channel (7), and when the transportation module (8) moves to the notch (9) of any layer, the transportation module (8) can form a closed circular ring railway with the annular railway (2) of the current layer;
• the platform bracket (4) is movably arranged on the transportation module (8) and each layer of the annular railway (2), and a parking platform (3) is arranged on each of the platform bracket (4), the rotating power system (6) drives the platform bracket (4) to move on the closed circular ring railway, so as to realize position displacement of the platform bracket (4) between the transportation module (8) and the annular railway (2) of the current layer;
• the platform interlocking system comprises a pushing mechanism and a locking mechanism (10), each locking mechanism (10) is arranged at a position of each layer of the annular railway (2) close to the notch (9), and the locking mechanism (10) on the annular railway (2) where the transportation module (8) does not stay is in a locked position, so as to lock the platform bracket (4) on the annular railway (2) of the current layer;
• each platform bracket (4) is configured with the pushing mechanism;
• and when the transportation module (8) moves to the notch (9) of any layer and forms the closed circular ring railway, the pushing mechanism drives the platform bracket (4) on the transportation module (8) to be in a force application position, so as to trigger the locking mechanism (10) and enable the locking mechanism (10) to unlock the platform bracket (4) on the annular railway (2) of the current layer;
• each layer of the locking mechanism (10) comprises:
• a locking rod, wherein a middle part of the locking rod is hinged to the annular railway (2), one end of the locking rod is provided with a boss which can prevent the platform bracket from moving along the annular railway (2), and the other end thereof is provided with an unlocking part which is configured to be pressed in a contact manner by the platform bracket (4) on the transportation module (8);
• and
• a return spring, wherein the return spring is arranged between the locking rod and the annular railway (2), and can maintain a locking state of the boss to the platform bracket (4), and after the unlocking part is pressed in a contact manner by the platform bracket (4), the locking state is released.
