[0034] The anti-collision working process of the parking lifting column of this embodiment is as follows: after the control circuit board receives the instruction through the wireless communication module, the drive motor is started, the drive motor starts to work, drives the screw to rotate, the screw rotates in the screw fixing nut and then drives the push rod outer column to move, the push rod outer column moves upward or downward along the push rod inner column under the guidance of the convex ridge and the groove, the movement of the push rod outer column then drives the entire inner column to move, the inner column moves upward or downward relative to the outer column under the cooperation of the notch spring and the guide groove, and the guide groove has the functions of guiding, positioning and motion stroke limiting. When the inner column moves upward relative to the outer column, if it encounters a foreign object, the inner column is restricted, and the resistance of the foreign object is transmitted to the push rod inner column and the eccentric plate through the screw. Under the action of the resistance of the foreign object, the blocked spring is further compressed, and at the same time, the reset switch spring sheet is also compressed, and its contact portion contacts the reset switch, and the reset switch generates an electrical signal to the control circuit board. After receiving the electrical signal, the control circuit board controls the drive motor to stop running, thereby realizing the anti-collision function.
