[0002] The design inspiration of the anti-skid bionic foot comes from the excellent anti-skid performance of animal feet such as goats and yaks. The foot structure of these animals has unique anti-skid characteristics such as foot shape, toe bone arrangement, and hoof box material. Therefore, in the design of bionic feet, these characteristics will be imitated to enhance the friction with the ground and improve the anti-skid performance. The bionic foot can automatically adjust the force position according to the inclination angle and hardness of the ground to ensure stable contact with the ground.
[0003] However, the dynamic self-adaptive mechanism of the bionic foot can only adjust the force position and contact area within a certain range. When encountering terrain conditions beyond the adjustment range, the anti-skid performance of the bionic foot may not meet the requirements. Although the anti-skid bionic foot improves the walking ability of the robot on complex terrain to a certain extent, its adaptability is still limited.

[0042] As shown in Figures 1 to 10 The top end of the bionic foot body 1 is fixed with a first connecting block 8, the inner wall of the first connecting block 8 is fixed with a limiting disc 9, the inner wall of the limiting disc 9 is provided with a connecting ball 10, the top end of the connecting ball 10 is fixed with a mounting rod 11, the outer wall of the mounting rod 11 is fixed with a buffer mechanism 12, the top end of the mounting rod 11 is fixed with a bionic leg bone 13, the anti-skid lines 3 are provided with a plurality of groups of openings in the bottom end of the bionic foot body 1, the air inlet 5 and the air outlet 6 are symmetrically distributed about the central axis of the air pump 4, the limiting disc 9 is provided with five groups of fixed inner walls of the first connecting block 8, the inner wall of the limiting disc 9 is close to the outer wall of the connecting ball 10, and the limiting disc 9 and the connecting ball 10 are rotationally connected.
[0043] By rotationally connecting the connecting ball 10 between the five groups of limiting discs 9, the mounting rod 11 and the bionic leg bone 13 above the connecting ball 10 can be rotated at a certain angle, and the first connecting block 8 can limit the range of rotation to a certain extent to achieve the purpose of bionic movement.
[0044] As shown in Figures 1 to 10 The buffer mechanism 12 includes a fixed plate 1201, a connecting seat 1202 and a second connecting block 1203, the fixed plate 1201 is fixed on the outer wall of the mounting rod 11, the bottom end of the fixed plate 1201 is fixed with the connecting seat 1202, one end of the connecting seat 1202 is rotationally connected with the second connecting block 1203, the bottom end of the second connecting block 1203 is fixed with a damper 1204, the outer wall of the damper 1204 is sleeved with a return spring 1205, the second connecting block 1203 is provided with two groups, the second connecting block 1203 is symmetrically distributed about the central axis of the fixed plate 1201, the damper 1204 is fixed at the top end of the bionic foot body 1, the damper 1204 is provided with two groups, the damper 1204 is symmetrically distributed about the central axis of the fixed plate 1201, and the return spring 1205 is used to press the second connecting block 1203 and keep it moving upward.
[0045] When the mounting rod 11 and the bionic leg bone 13 are rotated, a certain angle is generated, at this time the return spring 1205 at the bottom of the fixed plate 1201 in the bending direction first absorbs the pressure applied at the top end and stores this part of energy by deformation, and the damper 1204 converts the energy released by the return spring 1205 into heat energy for dissipation by its damping function, thereby reducing the amplitude and frequency of the vibration generated during movement. After the action, the top end no longer applies pressure, and after the impact force disappears, the return spring 1205 will try to restore to the original state and release the stored energy. At this time, the damper 1204 will dampen the rebound of the return spring 1205, so that the rebound of the return spring 1205 becomes slow and stable, thereby avoiding causing certain damage to the device when resetting after the rebound.
[0046] The working principle and working process of the embodiment are as follows:
[0047] By setting the bionic heel 2, the bionic heel 2 can play a supporting role when the device walks, and by setting a plurality of groups of anti-skid lines 3 at the bottom end of the bionic foot body 1, the shape of the anti-skid lines 3 can make the device have an anti-skid effect when walking, effectively preventing the device from sliding and falling when walking. By starting the air pump 4, the air pump 4 supplies air to the inside of the first air inlet seat 702 and the second air inlet seat 705 through the air supply hose 701. When adjusting the stress position angle, the electromagnetic valve at the first air inlet seat 702 is opened, and the electromagnetic valves at the two groups of second air inlet seats 705 are closed. At this time, the gas will only enter the inside of the first air guide groove 703 through the first air inlet seat 702, and push the rack 704, so that the rack 704 can drive the two groups of expansion plates 706 to rotate along the central axis of the second air inlet seat 705 when moving through the shape of the rack 704 and the shape of the teeth 708. After adjusting to the appropriate stress angle, the electromagnetic valve at the first air inlet seat 702 is closed, and the electromagnetic valves at the two groups of second air inlet seats 705 are opened. At this time, the airflow can enter the inside of the third air guide groove 709 through the second air guide groove 707, and can push the bottom block 710, so that the position of the bottom block 710 is lowered to the position in contact with the ground, thereby achieving the effect of adjusting the stress position of the device.
[0048] By cooperating the structures such as the air supply hose 701, the first air inlet seat 702, and the first air guide groove 703, the device can expand the area of the device contacting the ground after the two groups of expansion plates 706 are opened to a certain angle and the bottom block 710 is extended to contact the ground by starting the air pump 4 when walking, so that the device can better bear stress when walking, and the landing position of the bottom block 710 can be adjusted by changing the angle of rotation of the expansion plate 706, the stress position of the device can be changed, and the device can adapt to different terrains and quickly adapt to the walking of the road section when walking.
[0049] By rotating the connecting ball 10 between the five sets of limiting discs 9, the mounting rod 11 and the bionic leg bone 13 above the connecting ball 10 can rotate at a certain angle, and the first connecting block 8 can limit the range of rotation to achieve the purpose of bionic movement. When the mounting rod 11 and the bionic leg bone 13 rotate, they will produce a certain angle. At this time, the reset spring 1205 at the bottom of the fixed plate 1201 in the bending direction first absorbs the pressure applied at the top and stores this part of energy through deformation. The damper 1204 converts the energy released by the reset spring 1205 into heat energy for dissipation through its damping effect, thereby reducing the amplitude and frequency of the vibration generated during movement. After the action, the top no longer applies pressure, and after the impact force disappears, the reset spring 1205 will try to return to its original state and release the stored energy. At this time, the damper 1204 will dampen the rebound of the reset spring 1205, making the rebound of the reset spring 1205 slow and stable, thereby avoiding excessive vibration and damage to the device when resetting after rebounding.
[0050] By coordinating the structures of the fixed plate 1201, the connecting seat 1202, the second connecting block 1203, etc., the device can quickly reset the entire device when in use and walk, and can support the bionic leg bone 13. After the bionic leg bone 13 is bent forward by the mounting rod 11, the connecting ball 10, and the limiting disc 9, it is reset by the damper 1204 and the reset spring 1205. Because the damper 1204 and the reset spring 1205 are provided at the same time, they can buffer the bending and resetting actions, effectively preventing the device from being damaged by excessive rotation angle rate, and also providing a buffering effect during walking to protect the bionic leg bone 13 at the top and the components mounted on the bionic leg bone 13.
