[0007] The guardrail assembly includes two sets of side bottom railings, which are respectively hinged to the front and rear ends of the top of the main frame. Two sets of first railing latches are installed at the front and rear ends of the back panel. A side top railing is hinged to the top of the side bottom railing. A rear bottom railing is hinged to the left side of the top of the main frame. A rear top railing is hinged to the top of the rear bottom railing. Second railing latches are installed on the left side of the side bottom railing and the side top railing.

[0008] As a further technical solution of this utility model, the first drive wheel and the second drive wheel are the same size, and the first drive axle and the second drive axle have the same specifications.

[0009] As a further technical solution of this utility model, the connecting seat and the leaf spring suspension are movably connected, and the connecting frame is movably connected to the bottom end of the first drive axle and the second drive axle respectively.

[0010] As a further technical solution of this utility model, the top ends of the first drive wheel and the second drive wheel are lower than the bottom end of the main frame, and the bottom ends of the first drive wheel and the second drive wheel are flush.

[0011] As a further technical solution of this utility model, the tops of the side bottom fence and the rear bottom fence are flush, and the tops of the side top fence and the rear top fence are flush.

[0012] As a further technical solution of this utility model, the side bottom fence and the rear bottom fence are locked by the second railing buckle, and the side top fence and the rear top fence are locked by the second railing buckle. The first railing buckle and the second railing buckle are of the same specification.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the dual-drive off-road electric vehicle with guardrail structure not only realizes the function of strong dual-drive off-road capability, but also realizes the function of raising the guardrail to protect the cargo.

[0014] By setting up a connecting seat, a first drive axle, a first drive wheel, a second drive axle, a second drive wheel, a drive motor, a leaf spring suspension, and a connecting frame, when in use, the driver sits in the seat and controls the direction of the vehicle. The two sets of drive motors drive the first and second drive wheels to operate continuously through the first and second drive axles. The drive wheels are changed from one set to two sets. Even if either the first or second drive wheel gets stuck in mud or a pit, the other set can provide power to bring the vehicle out, thus enhancing its off-road capability. The leaf spring suspension and connecting frame work together to make the wheels move up and down smoothly, realizing the function of strong dual-drive off-road capability.

[0015] By incorporating side bottom railings, first side panel latches, side top railings, rear bottom railings, rear top railings, and second side panel latches, goods are stacked at the bottom of the main frame during use. The side bottom railings and rear bottom railings can surround the goods to prevent them from slipping during transportation. The side top railings and rear top railings enhance the protective capabilities of the railings. The first and second side panel latches can lock the railings, thus achieving the function of raising the railings to protect the goods. Attached Figure Description
