[0039] See also Figure 1 and Figure 2 This embodiment provides a robot 100, which includes a body 110, a foot 120, and a connection mechanism 130. The connection mechanism 130 includes a filling ring 131, a first connection part 132, and a second connection part 141. The first connection part 132 is connected to the body 110, and the second connection part 141 is connected to the foot 120. The first connection part 132 and the second connection part 141 can be firmly connected.

[0040] The filling ring 131 is disposed between the first connection portion 132 and the second connection portion 141 , and is used to fill a gap between the first connection portion 132 and the second connection portion 141 .

[0041] See also Figure 3 and Figure 4 A first hook 133 is disposed on the first connection portion 132. A second guiding inclined surface 134 is disposed on a side of the first hook 133 close to the elastic blocking piece.

[0042] The first connection portion 132 is provided with two limiting posts 135 , and the two limiting posts 135 are located at two opposite sides of the first hook 133 .

[0043] See also Figure 5 and Figure 6 The second connection portion 141 is provided with a mounting hole 142 , and the first connection portion 132 is inserted into the mounting hole 142 , so that the first connection portion 132 is fixed in a horizontal direction relative to the second connection portion 141 .

[0044] The second hook 143 and the limiting portion 144 are disposed in the mounting hole 142. The second hook 143 is formed by the side wall of the mounting hole 142, and the limiting portion 144 is disposed at the bottom of the mounting hole 142. The first hook 133 is engaged with the second hook 143, so that the first connection portion 132 is fixed in the vertical direction relative to the second connection portion 141. The limiting portion 144 enables the first hook 133 to be easily engaged with the second hook 143, and can effectively prevent the first hook 133 from being separated from the second hook 143.

[0045] Specifically, a base 146 is disposed in the mounting hole 142 . The base 146 is connected to the inner wall of the mounting hole 142 . A through hole 147 is formed on the base 146 at a position corresponding to the limiting portion 144 .

[0046] The second hook 143 is formed by the side wall of the mounting hole 142 , and the first hook 133 is engaged with the second hook 143 , that is, the first hook 133 is hooked on the edge of the side wall of the mounting hole 142 , so that the first connection portion 132 is fixed relative to the second connection portion 141 in the vertical direction.

[0047] The base 146 is provided with two limiting holes 148, which are located on opposite sides of the through hole 147. The limiting holes 148 correspond to the limiting posts 135 one by one, and the limiting posts 135 are inserted into the limiting holes 148, so that the first connection portion 132 can be effectively prevented from rotating relative to the mounting hole 142, thereby improving the stability of the connection.

[0048] In other embodiments, the limiting column 135 may also be disposed on the second connecting portion 141 , and correspondingly, the limiting hole 148 may be opened on the first connecting portion 132 .

[0049] The second hook 143 and the limiting portion 144 are arranged at intervals, and a first guiding slope 145 is arranged on one side of the limiting portion 144 close to the second hook 143. The gap between the first guiding slope 145 of the limiting portion 144 and the second hook 143 is smaller than the width of the first hook 133. When the first hook 133 is inserted between the limiting portion 144 and the second hook 143, the second guiding slope 134 of the first hook 133 will squeeze the first guiding slope 145 of the limiting portion 144, and the limiting portion 144 applies a thrust to the first hook 133, so that the first hook 133 moves toward the second hook 143. If the first hook 133 is continuously inserted into the mounting hole 142, it will be engaged with the second hook 143, and the deformation of the limiting portion 144 will be reduced or even reduced to zero. At the same time, the limiting portion 144 prevents the first hook 133 from being separated from the second hook 143, thereby ensuring that the first connecting portion 132 is firmly connected to the second connecting portion 141.

[0050] See also Figure 7 During the process of inserting the first hook 133 into the mounting hole 142, the second guide slope 134 of the first hook 133 presses the first guide slope 145 of the limiting portion 144, and the limiting portion 144 applies a thrust to the first hook 133, so that the first hook 133 moves toward the second hook 143 and engages with the second hook 143. After the first hook 133 engages with the second hook 143, the deformation of the limiting portion 144 is reduced or even reduced to zero, and at the same time, the limiting portion 144 prevents the first hook 133 from being separated from the second hook 143, ensuring that the first connection portion 132 is firmly connected to the second connection portion 141.

The first hook 133 is engaged with the second hook 143 , so that the first connection portion 132 is fixed relative to the second connection portion 141 in the vertical direction.

[0053] 2. The first hook 133 is inserted into the mounting hole 142 to fix the first connecting portion 132 in a horizontal direction relative to the second connecting portion 141 .

[0054] 3. During the process of inserting the first hook 133 into the mounting hole 142, the first hook 133 squeezes the first guide slope 145 of the limiting portion 144, and the limiting portion 144 applies a thrust to the first hook 133, so that the first hook 133 moves toward the second hook 143 and engages with the second hook 143. In this way, the limiting portion 144 can effectively prevent the first hook 133 from being separated from the second hook 143, so that the first connecting portion 132 and the second connecting portion 141 are firmly connected, and the connection strength between the body portion 110 and the foot portion 120 of the robot 100 is strengthened.
