[0031] The support plate 2-3 includes an integrally formed motor-side mounting panel and a drive-side mounting panel. The motor-side mounting panel is lower than the drive-side mounting panel, and the mating position of the motor-side mounting panel and the drive-side mounting panel forms a first step. The motor-side mounting panel is provided with motor bearing sleeve mounting holes 2-5 and two motor mounting plate slots 2-6, which are located on both sides of the motor bearing sleeve mounting holes 2-5. The output shaft of the steering motor 3-1 passes through the motor bearing sleeve mounting holes 2-5. The drive-side mounting panel is provided with a drive bearing sleeve mounting hole 2-4 located in the middle.

[0032] The drive-side mounting panel is provided with a zero-point sensor mounting hole 2-8, which is located on the side of the drive bearing sleeve mounting hole 2-4 away from the motor bearing sleeve mounting hole 2-5.

[0040] The bearing structure of the second connecting shaft 3-8 is installed in the drive bearing sleeve mounting hole 2-4 to ensure stable rotation of the second connecting shaft 3-8. Specifically, the drive bearing pad 3-12 is spaced between the second bearing 3-14 and the drive synchronous pulley 3-11 to prevent misalignment of the synchronous pulley; the drive bearing sleeve 3-13 stabilizes the second connecting shaft 3-8 and ensures its concentricity; the second bearing 3-14 ensures the concentricity and rotation of the second connecting shaft 3-8; and the drive connecting shaft bearing retainer 3-15 ensures the stability of the second connecting shaft 3-8 and prevents displacement.

[0041] The drive mechanism 4 is installed below the drive mounting plate 3-9. The drive mechanism 4 includes two drive wheel fixing plates 4-1 and a drive wheel 4-2. The two drive wheel fixing plates 4-1 are symmetrically arranged on both sides below the drive mounting plate 3-9. The drive wheel 4-2 is installed between the two drive wheel fixing plates 4-1 by drive wheel locking nuts 4-3. The drive wheel 4-2 is the power source for forward or backward movement. The drive wheel locking nuts 4-3 fix and lock the drive wheel 4-2. Additionally, a drive wheel anti-rotation plate can be provided to prevent the drive wheel 4-2 from reversing.

[0042] This invention provides a simplified steering wheel design, in which the steering mechanism is designed as a motor-side assembly and a drive-side assembly. In the motor-side assembly, the output shaft of the steering motor is connected to a motor synchronous pulley via a first connecting shaft. In the drive-side assembly, the same drive synchronous belt is fitted onto both the motor synchronous pulley and the drive synchronous pulley. The drive synchronous pulley is connected downwards to a drive mounting plate via a second connecting shaft, and upwards to a second bearing, which is then mounted to a support plate. This creates two parallel linkage mechanisms on the support plate. The downward connection via the drive mounting plate enables faster rotation or movement in place, while the upward connection allows for switching between different mounting plates depending on the mounting surface. Furthermore, a buffer mechanism is provided beneath the fixed plate to reduce vibrations during rotation or movement.
