[0023] The step assembly is connected to the vehicle body by setting up a connecting frame 1 that cooperates with the trailer frame on the vehicle body. This makes it easier for users to step on the steps and increase their standing height, making it easier to retrieve and place items from the roof of the vehicle. A fastening component is installed between the connecting frame 1 and the trailer frame. After the connecting frame 1 is installed on the vehicle body, the fastening component is adjusted to fix the connecting frame 1 and the trailer frame in place. This achieves the fastening of the step assembly on the vehicle body, improves the stability of the step assembly, and prevents the connecting frame 1 from shaking and causing abnormal noise, or even affecting the use of the steps and causing injury to the user.

[0024] In the step support structure of this embodiment, the overlapping frame 1 is provided with a sleeve interface 2. The shape of the sleeve interface 2 matches the shape of the trailer frame, and the overlapping frame 1 is fitted with the trailer frame through the sleeve interface 2.

[0025] Specifically, the trailer frame includes a trailer arm 12 and a connecting seat 13 fixed to the vehicle body. The trailer arm 12 and the connecting seat 13 are detachably connected. The connecting seat 13 is a tubular structure fixed to the rear bumper of the vehicle body. The trailer arm 12 is inserted into the connecting seat 13, and then the connection and limiting of the two are achieved by a limiting pin passing through the connecting seat 13 and the trailer arm 12.

[0026] Preferably, the longitudinal sections of the trailer arm 12 and the connecting seat 13 are square.

[0027] The upper sleeve 2 of the overlapping frame 1 is square. The overlapping frame 1 is fitted onto the trailer arm 12 with a gap fit. Then the trailer arm 12 is inserted into the connecting seat 13. The square sleeve 2 cooperates with the square trailer arm 12 to initially limit the overlapping frame 1 and prevent the overlapping frame 1 from flipping in the vertical plane.

[0028] In the step support structure of this embodiment, the fastening component includes a fastening plate 3, which passes through the overlapping frame 1 and is slidably connected to the overlapping frame 1. Both sides of the fastening plate 3 are respectively abutted against the trailer frame by fasteners.

[0029] Specifically, the lap joint 1 is provided with an installation port 8 for inserting the fastening plate 3. The socket 2 and the installation port 8 are separated by a limiting block 9. The limiting block 9 limits the fastener to prevent the fastening plate 3 from detaching from the lap joint 1.

[0030] Before the connecting frame 1 is connected to the trailer arm 12, insert the fastening plate 3 into the mounting port 8. After the connecting frame 1 is installed on the trailer arm 12, adjust the fasteners on both sides to fix the connecting frame 1 and the trailer arm 12.

[0031] Preferably, after the connecting frame 1 and the trailer frame are installed, the position of the fastening plate 3 is adjusted so that the fastening plate 3 is set along the extension direction of the trailer arm 12, and the fasteners on both sides abut against the connecting seat 13 and the trailer arm 12 respectively, so as to achieve a stable connection between the step assembly and the entire trailer frame.

[0032] Specifically, the step assembly also includes a connecting frame 10 located below the connecting frame 1 and fixedly connected to the connecting frame 1, with step bodies 11 for supporting the feet fixedly installed at both ends of the connecting frame 10.

[0033] Preferably, the lap frame 1 is a square frame, the connecting frame 10 is welded to the bottom of the lap frame 1, and the two step bodies 11 are symmetrically welded to both ends of the connecting frame 10. The step is set as a split structure, and the user can step on the step bodies 11 on both sides respectively, which is convenient for standing. At the same time, the user's legs are spread apart, which provides better stability.

[0034] In the step support structure of this embodiment, the fastener includes a fixing post 4 located on one side of the fastening plate 3. The fixing post 4 is fixedly connected to the fastening plate 3, and two fixing posts 4 are arranged in a direction parallel to the overlapping frame 1.

[0035] The fixing post 4 is fixedly connected to the fastening plate 3. When the fastener on the other side is adjusted, the fixing post 4 is driven by the fastening plate 3 to press against the trailer arm 12, pressing the trailer arm 12 and the connecting frame 1, limiting the two so that they are tightly connected, and realizing the stable installation of the step assembly. Two fixing posts 4 are set to abut against the trailer arm 12 from the left and right sides to further improve stability.

[0036] In the step bracket structure of this embodiment, the fastener also includes a movable column 5 disposed opposite to the fixed column 4. The length of the movable column 5 extending out of the surface of the fastening plate 3 is adjustable so as to adjust the distance between the fastening plate 3 and the trailer frame.

[0037] Specifically, the extension length of the movable column 5 is adjusted so that its end abuts against the connecting seat 13. The movable column 5 limits the connecting seats 13 and the fastening plate 3 on both sides from the middle, so that their positions are fixed. It also drives the fixing column 4 at the other end of the fastening plate 3 to approach the trailer arm 12 and abut against it. It limits the overlap frame 1 and the trailer frame from both sides, thereby achieving stable installation of the step assembly.

[0038] In the step support structure of this embodiment, the movable column 5 is threadedly connected to the fastening plate 3, and the end of the movable column 5 is fixedly connected to the adjusting nut 6. Rotating the adjusting nut 6 causes the movable column 5 to extend and abut against the trailer frame, thereby cooperating with the fixed column 4 to fix the overlapping frame 1 to the trailer frame.

[0039] Specifically, the movable column 5 is a bolt that passes through the fastening plate 3. By rotating the adjusting nut 6 from the bottom of the movable column 5, the movable column 5 can extend out of the fastening plate 3 and further adjust the distance between the fastening plate 3 and the connecting seat 13, so as to limit and fix the fastening plate 3 and the connecting seat 13.

[0040] Preferably, there is one movable column 5, and the movable column 5 and the two fixed columns 4 are distributed in an isosceles triangle, so that the fastening plate 3 is subjected to uniform force and the connection stability of the overlapping frame 1 and the trailer arm 12 is improved.

[0041] In the step support structure of this embodiment, a locking nut 7 is threadedly connected to the periphery of the movable column 5. The locking nut 7 is located between the fastening plate 3 and the adjusting nut 6. Rotating the locking nut 7 causes the locking nut 7 to abut against the fastening plate 3, thereby locking the fastening plate 3.

[0042] With the above settings, after the movable column 5 and the connecting seat 13 are pressed together, the locking nut 7 is rotated to move it upward until it is in contact with the lower surface of the fastening plate 3, which further locks the connection between the movable column 5 and the fastening plate 3 and enhances stability again.

[0043] Based on the above structure, the locking nut 7 and adjusting nut 6 can be used to fix or loosen the connecting frame 1 and the trailer frame. With the detachable structure of the trailer arm 12 and the connecting seat 13, it is convenient to install and disassemble the step structure and the vehicle body. The step can be used as needed. At the same time, the fastening components can ensure the stability of the step structure, avoid abnormal noise or loosening, improve the use effect, and provide great convenience for users to take items on the top of the vehicle body.
