The mounting frame 2 is mounted on the front side of the robot body 1, and the hinge seat 8 is mounted on the mounting frame 2. The hinge seat 8 has a first fixing hole 81 and a second fixing hole 82. One end of the first link assembly 3 is swayably mounted on the hinge seat 8, and the other end of the first link assembly 3 is hinged to the swing frame 5. The first link assembly 3 has a first locking hole 301, which can... The first fixing hole 81 is directly opposite to the second fixing hole 82. One end of the second connecting rod assembly 4 is swayably mounted on the hinge seat 8, and the other end of the second connecting rod assembly 4 is hinged to the swing frame 5. The second connecting rod assembly 4 is provided with a second locking hole 401, which is directly opposite to the second fixing hole 82. The support roller 6 is rotatably mounted on the swing frame 5. When the pin 7 is installed in the first fixing hole 81 and the first locking hole 301, the swing frame 5 is in a retracted state. When the pin 7 is installed in the second fixing hole 82 and the second locking hole 401, the swing frame 5 is in an extended state.In this embodiment, one end of the first connecting rod assembly 3 is swayably mounted on the top of the hinge seat 8, and one end of the second connecting rod assembly 4 is swayably mounted on the bottom of the hinge seat 8.

When the support roller 6 is in the retracted state, the second fixing hole 82 is directly opposite the second locking hole 401, and the pin 7 is inserted into the second fixing hole 82 and the second locking hole 401. At this time, under the fixation of the pin 7, the second connecting rod assembly 4 cannot swing. At the same time, the second connecting rod assembly 4 fixes the first connecting rod assembly 3 through the swing frame 5, thereby making the entire front support roller... When the wheel assembly is fixed and the support roller 6 needs to be unfolded, the pin 7 is removed from the second fixing hole 82 and the second locking hole 401, allowing the second connecting rod assembly 4 and the first connecting rod assembly 3 to swing. During the swinging process of the first connecting rod assembly 3 and the second connecting rod assembly 4, the swing frame 5 drives the support roller 6 to swing and unfold adaptively until the fixing hole 81 is aligned with the first locking hole 301. At this time, the swing frame 5 drives the support roller 6 to be in a fully unfolded state. Then, the pin 7 is inserted into the first fixing hole 81 and the first locking hole 301 to fix the first connecting rod assembly 3. The first link assembly 3 fixes the second link assembly 4 through the swing frame 5, thereby fixing the entire front support roller assembly. This application uses the robot body 1, mounting frame 2, first link assembly 3, first locking hole 301, second link assembly 4, second locking hole 401, swing frame 5, roller 6, pin 7, hinge seat 8, first fixing hole 81 and second fixing hole 82 to swing open and close the roller 6 so that it can be folded and unfolded for support.

The adjustment holes 211 are oblong holes. The mounting frame 2 is mounted to the front side of the robot body 1 through the adjustment holes 211, and the mounting frame 2 can move left and right along the length direction of the adjustment holes 211, thereby adjusting the position of the support roller 6 and ensuring the support quality of the support roller 6.
[0037] like Figure 3-4 As shown, the mounting frame 2 is provided with a reinforcing block 22. One end of the reinforcing block 22 is connected to the mounting plate 21, and the other end of the reinforcing block 22 is connected to the top surface of the mounting frame 2. In this embodiment, the reinforcing block 22 is provided on the top surface of the mounting frame 2, so that one end of the reinforcing block 22 is connected to the mounting plate 21, and the other end of the reinforcing block 22 is connected to the top surface of the mounting frame 2. This helps to strengthen the connection stability between the mounting plate 21 and the mounting frame 2, making it more integrated and structurally more stable.
