This invention discloses a semi-trailer logistics van that utilizes solar energy for auxiliary power. It includes a tractor unit and a semi-trailer frame connected together. Hub motors are installed in the driven wheels at the bottom of the semi-trailer frame, providing auxiliary power to the semi-trailer. Working in conjunction with the tractor unit, this enhances the vehicle's ability to navigate challenging road conditions such as inclines and declines. After the tractor unit separates from the semi-trailer, the semi-trailer can turn and move due to the speed difference between the hub motors on both sides. It can autonomously move to a designated loading / unloading position after detaching from the tractor unit, eliminating the need for reversing or other maneuvers on the tractor unit. The tractor unit simply pulls the semi-trailer to the vicinity of the designated loading / unloading position, thus improving loading and unloading efficiency to a certain extent. A generator housing with solar panels is also installed on the trailer, providing the necessary electrical energy to the hub motors and other power components, effectively increasing the vehicle's driving range. The generator housing also includes a cleaning drum, allowing the solar panels to be moved to the cleaning drum for cleaning, improving surface cleanliness and ensuring power generation performance.
