[0002] Robot foot assembly refers to the component installed at the end of the robot's legs. It typically includes a foot shell, a foot plate, and multiple gravity sensors. The main function of the foot assembly is to provide a contact point with the ground and monitor the center of gravity of the foot through gravity sensors, thereby helping the robot maintain balance and stability.

[0003] To this end, patent No. 202020225436.1 discloses a self-balancing footplate for robots, including a robot body with a controller for controlling the operation of various components, a footplate body fixedly installed below the robot body, and a toe structure connected to the footplate body. The footplate body has a concave opening on its end face near the toe structure; the toe structure connects to the footplate body at the concave opening; the footplate body includes a rectangular footplate and a leg connecting column, which connects the footplate to the robot body; the toe structure includes toes covered with strain gauges and a servo structure, which connects the toes to the footplate; and toe connecting pieces located on both sides of the concave opening, which connect the footplate to the servo structure. The advantages of this invention are: simple mechanical structure, low manufacturing cost, and easy to promote and utilize; the double-toe design allows the two toes to rotate at different angles, improving balance.

[0004] The existing technical solutions mentioned above have the following drawbacks: Although the two-toe design can be used to enable the two toes to rotate at different angles and improve balance, due to the special overall structure of the robot foot plate assembly, the internal installation space is not only relatively narrow, but the structure in which the gravity sensor is installed is also relatively complex. It requires the staff to use external tools to disassemble and assemble the robot in a relatively narrow space, which is inconvenient for the staff to operate and increases the difficulty of the work.

[0048] The threaded rod 24 and the screw block 25 are set on the same central axis. There are two sets of screw blocks 25. The insert frame 22 is used to provide space for the tooth block 26 to be inserted, so that the tooth block 26 can be precisely meshed with the rotating gear 23.

[0049] With the auxiliary cooperation between the toothed block 26 and the insert frame 22, the heel shell 12 can be pulled out upwards, while the toothed block 26 and the rotating gear 23 can be meshed and connected, and the two sets of screw blocks 25 can be released from the clamping of one end of the gravity sensor 17.

[0050] Working principle: When staff disassemble and repair the robot's rubber sheet assembly;

[0051] First, by removing the installation between the heel shell 12 and the sole plate 11, the staff can lift the heel shell 12 upwards, while the toothed block 26 slides vertically inside the insert frame 22, allowing the toothed block 26 to mesh with the rotating gear 23, and the screw block 25 to slide vertically inside the placement groove 21 along the threaded trajectory outside the threaded rod 24.

[0052] Next, the clamping force formed by the two sets of screw blocks 25 on one end of the gravity sensor 17 can be released, thereby allowing...

[0053] This releases the limiting position between the placement slot 21 and the gravity sensor 17, making it easier for staff to pick up the gravity sensor 17.

[0054] This step can help staff to quickly disassemble and retrieve the gravity sensor 17, and provide staff with ample space for inspection and disassembly.

[0055] Please see Figure 4-5 As shown, this embodiment, based on the above embodiment, also includes a disassembly and assembly component;

[0061] With the auxiliary cooperation between the slide groove 31 and the slider 32, the position of the slider 32 can be slid according to the actual installation requirements, and at the same time, the sliding movable block 33 makes the movable block 33 and the slot 36 engage.

[0062] Working principle: When the staff installs the drive motor 15;

[0063] First, according to the specifications of the installed parts and drive motor 15, the staff slides the slider 32 inside the sliding groove 31 so that the slider 32 can slide to the appropriate position. Then, the staff slides the movable block 33 inside the slider 32 so that one end of the movable block 33 extends and engages with the inside of the slot 36.

[0064] Next, by sliding the movable block 33, the retaining strip 35 can be slid inside the mounting frame 14. This allows the retaining strip 35 to drive the mounting piece 34, which is fixedly connected at one end, to slide horizontally, aligning the groove on the mounting piece 34 with the mounting groove 16.
