The rear wheel chock 52 primarily contacts the rear of the vehicle's tires to restrict backward movement of the vehicle during unloading. In this embodiment, there are two front wheel chocks 51 and two rear wheel chocks 52, spaced apart along the width of the tilting platform 30 to ensure effective contact with both tires in the width direction of the vehicle. Additionally, each rear wheel chock 52 is equipped with two second distance sensors 62. It is understood that when the first distance sensor 61 detects a vehicle, both rear wheel chocks 52 rise halfway up, exposing the second distance sensors 62, while the two front wheel chocks 51 remain stationary, allowing the rear wheels of the vehicle to move between the front wheel chocks 51 and the rear wheel chocks 52. When the second distance sensor 62 on the rear wheel chock 52 measures the appropriate distance between the wheel chock and the car tire, all the front wheel chocks 51 and rear wheel chocks 52 are raised, thereby securing the vehicle. Preferably, the two second distance sensors 62 can be of different types to reduce interference between the two sensors and improve the reliability of the reversing assist component 60.
