The batteries 9 power the drive motors 7 on the obstacle-crossing wheels 2, enabling them to rotate and, in turn, propel the entire transporter forward and backward. This design enables the transporter to not only move autonomously but also automatically adjust the wheel height when encountering obstacles, ensuring smooth traversal.

[0033] In the preferred embodiment, the two obstacle-crossing wheels 2 are connected in the middle by a rotating shaft to form a group, the rotating shaft is rotatably connected to the lifting frame 10, the drive motor 7 is fixed in the middle position of the lifting frame 10, the drive motor 7 is connected to the rotating shaft through a gear box, and the two ends of the lifting frame 10 are connected to the telescopic rod of the telescopic cylinder 3.

[0034] The two obstacle-crossing wheels 2 are connected as a group via a central rotating shaft, which is rotatably connected to the lifting frame 10, ensuring that the wheels can rotate freely. The drive motor 7 is fixed to the center of the lifting frame 10 and connected to the rotating shaft via a gearbox, providing power to rotate the obstacle-crossing wheels 2. The two ends of the lifting frame 10 are connected to the telescopic rod of the telescopic cylinder 3. When the telescopic cylinder 3 is working, the telescopic rod can be extended and retracted to drive the lifting frame 10 up and down, thereby adjusting the height of the obstacle-crossing wheels 2. The lifting frame 10 not only supports the installation of the obstacle-crossing wheels 2, but also provides a fixed position for the drive motor 7, ensuring the stability and reliability of the entire system.

[0035] In the preferred embodiment, the lower surface of the chassis 1 is provided with four obstacle-crossing wheels 2, or six obstacle-crossing wheels 2, or multiple obstacle-crossing wheels 2. The present application preferably has six obstacle-crossing wheels 2, of which four of the six obstacle-crossing wheels 2 are equipped with drive motors 7, such as Figure 1-4 shown.

[0036] In the preferred embodiment, the support base 5 includes a support frame 501, which is arranged on the bearing cover 101. The support frame 501 has a U-shaped structure. A transverse frame 504 is provided at the upper opening of the support frame 501. At least two adjustment mounting plates 502 are provided on the transverse frame 504.
