[0031] In the related art, the sole of the humanoid robot can be provided with a bottom plate, which is usually made of rubber and other materials, has certain wear resistance and slip resistance, and can realize more stable operation of the robot. However, the bottom plate of the existing humanoid robot is mostly directly pasted and fixed on the sole of the robot by using adhesive, and the stability of the adhesive is poor, which can cause the bottom plate to separate from the adhesive after the robot operates for a period of time, so that the bottom plate cannot fully cover and protect the sole of the robot, and the practicability and reliability of the bottom plate of the humanoid robot are reduced. In view of the above problems, the utility model provides a humanoid robot bottom plate 100.

[0032] Please refer to Figures 1 to 8 In an embodiment of the utility model, the humanoid robot bottom plate 100 has opposite first surface 10a and second surface 10b, first surface 10a is used to connect with robot sole 200, first surface 10a is equipped with at least one limiting structure 30, limiting structure 30 is used to cooperate with robot sole 200 and is clamped, first surface 10a is formed with rough texture (not shown), second surface 10b is equipped with anti-skid structure 50.

[0033] It can be understood that a bionic machine device such as a robot can generally be provided with a bionic foot to realize the walking function. In order to improve the service life of the robot, a bottom plate 100 can generally be arranged at the bottom of the foot 200 of the humanoid robot. The wear-resistant and anti-skid properties of the bottom plate 100 can effectively prevent the robot from slipping and reduce the wear of the foot of the robot, so that the robot can operate more stably and reliably.

[0034] In the present application, the humanoid robot bottom plate 100 can be made of a plastic material with certain elasticity and flexibility, and at the same time, the humanoid robot bottom plate 100 can be made of a composite plastic material, so that the humanoid robot bottom plate 100 can have better wear-resistant performance, insulation performance and structural strength, and improve the service life of the humanoid robot bottom plate 100. The shape and size of the first surface 10a of the humanoid robot bottom plate 100 can be designed to correspond to the shape and size of the bottom of the foot 200 of the robot, so that the humanoid robot bottom plate 100 can fully cover and protect the bottom of the foot 200 of the robot, and reduce the wear of the bottom of the foot 200 of the robot. At this time, the second surface 10b of the humanoid robot bottom plate 100 can be the surface in contact with the ground when the robot walks. The anti-skid structure 50 on the second surface 10b can be designed to be an array of protrusions 51 or a groove pattern, which is beneficial to disperse contact stress and improve the gripping performance of the humanoid robot bottom plate 100, and effectively prevent the robot from slipping when walking.

[0035] The limiting structure 30 on the first surface 10a of the humanoid robot bottom plate 100 can refer to a physical member capable of forming mechanical interlocking with the bottom of the foot 200 of the robot, which can be realized by a hole or a columnar protrusion, or can be realized by a mutually cooperating buckle structure, for preventing lateral displacement between the humanoid robot bottom plate 100 and the bottom of the foot 200; the rough texture on the first surface 10a can refer to a microscopic irregular topography formed by surface processing, such as a grid-like texture or an irregular concave-convex surface texture, which can be realized by sandblasting treatment or mold forming, for increasing the friction coefficient of the contact surface. Further, when the humanoid robot bottom plate 100 is connected to the bottom of the foot 200 of the robot through the first surface 10a, the limiting structure 30 and the corresponding part of the bottom of the foot 200 are embedded with each other to form a physical constraint, which can effectively resist the relative displacement caused by shear force, and is beneficial to realize the positioning and installation of the humanoid robot bottom plate 100 and the bottom of the foot 200 of the robot, prevent the humanoid robot bottom plate 100 from being assembled to deviate, and can limit the relative movement between the humanoid robot bottom plate 100 and the bottom of the foot 200 of the robot, so as to avoid the humanoid robot bottom plate 100 from being separated from the bottom of the foot 200 of the robot. At this time, the rough texture can suppress the tendency of slight sliding by increasing the surface friction, and the limiting structure 30 on the humanoid robot bottom plate 100 can be used in cooperation with the rough texture to realize stable fixation, which can better improve the connection stability and reliability of the humanoid robot bottom plate 100 and the bottom of the foot 200 of the robot.

[0036] It should be noted that the humanoid robot bottom plate 100 can be bonded with the robot foot bottom 200 by using adhesive coated on the first surface 10a, and the adhesive bonding effect can be better enhanced by using the rough texture on the first surface 10a, and the mutual clamping and limiting of the humanoid robot bottom plate 100 and the robot foot bottom 200 by using the limiting structure 30 can reduce the shear force received by the adhesive layer, and realize more stable installation of the humanoid robot bottom plate 100; or the humanoid robot bottom plate 100 can be fastened and connected with the robot foot bottom 200 by using bolts, latches or buckles, and the humanoid robot bottom plate 100 can be better fastened and installed on the robot foot bottom 200, and the connection stability and reliability of the humanoid robot bottom plate 100 and the robot foot bottom 200 can be improved.

[0037] The technical scheme of the utility model discloses a limiting structure 30 is arranged on the first surface 10a of the humanoid robot bottom plate 100 towards the robot foot bottom 200, the limiting structure 30 can be groove or through -hole structure setting, at this time, the latch that cooperates with the limiting structure 30 can be set on the robot foot bottom 200, and the plug -in limiting fixing of the humanoid robot bottom plate 100 and the robot foot bottom 200 is realized;Or, the limiting structure 30 can be plug -in convex, at this time, the groove or the insertion hole that cooperates with the limiting structure 30 can be set on the robot foot bottom 200, and the plug -in limiting fixing of the humanoid robot bottom plate 100 and the robot foot bottom 200 is realized. In this way, the limiting structure 30 can be used to realize the stable and fixed installation of the humanoid robot bottom plate 100 and the robot foot bottom 200, effectively avoid the deviation of the humanoid robot bottom plate 100 in the assembly process, by forming rough texture on the first surface 10a of the humanoid robot bottom plate 100, the contact friction of the humanoid robot bottom plate 100 and the robot foot bottom 200 can be effectively increased, and when the humanoid robot bottom plate 100 and the robot foot bottom 200 are bonded by using adhesive, the adhesive can penetrate into the rough texture, and the relative movement of the humanoid robot bottom plate 100 and the robot foot bottom 200 is limited by the limiting structure 30, the stability and reliability of the connection of the humanoid robot bottom plate 100 and the robot foot bottom 200 can be better improved, the humanoid robot bottom plate 100 is prevented from being separated from the robot foot bottom 200, and the practical durability of the humanoid robot bottom plate 100 is effectively improved.

[0038] Referring to Figure 1 , Figure 4 , Figure 5 And Figure 6 In an embodiment of the utility model, the limiting structure 30 is a limiting hole 31, and the limiting hole 31 is used for plug-in of the convex of the robot foot bottom 200.

[0039] In the embodiment, the limiting hole 31 can refer to a hole structure formed on the first surface 10a, which can be realized by machining or mold forming, etc. At this time, a protrusion can be arranged on the robot sole 200 to cooperate with the limiting hole 31, or the limiting hole 31 can be arranged corresponding to the original protrusion position on the robot sole 200, so that the limiting hole 31 accommodates the protrusion of the robot sole 200 and forms a physical clamping, realizing the stable connection of the humanoid robot bottom plate 100 and the robot sole 200.

[0040] When the humanoid robot bottom plate 100 is in contact with the robot sole 200 through the first surface 10a, the protruding part on the robot sole 200 is guided to be inserted into the limiting hole 31, and the inner wall of the hole and the side surface of the protrusion form a close fit, which utilizes the geometric constraint of the hole structure to limit the horizontal displacement, and at the same time forms a stable supporting effect through the vertical direction of the insertion depth control. During the movement of the robot, the insertion structure bears the force from the robot sole 200, avoiding the risk of falling of the humanoid robot bottom plate 100 due to the failure of the adhesive, and further improving the structural stability and reliability of the humanoid robot bottom plate 100.

[0041] Further, in an embodiment of the utility model, the limiting hole 31 is arranged through the first surface 10a and the second surface 10b, the limiting hole 31 includes the first hole section and the second hole section that are connected, one end of the first hole section is arranged through the first surface 10a, one end of the second hole section is arranged through the second surface 10b, and the hole diameter of the first hole section is less than the hole diameter of the second hole section.

[0042] In the embodiment, by arranging the limiting hole 31 through the first surface 10a and the second surface 10b, the limiting hole 31 can be more conveniently machined on the humanoid robot bottom plate 100, and at the same time, the depth of the protrusion of the robot sole 200 inserted into the limiting hole 31 is effectively guaranteed by the through hole design, improving the stability of the humanoid robot bottom plate 100 and the robot sole 200 cooperating with the insertion.

[0043] By making the limiting hole 31 include a second hole section with a larger hole diameter and a first hole section with a smaller hole diameter, the protrusion of the robot sole 200 can be designed to include a rod portion that fits the size of the first hole section and an expansion portion that fits the size of the second hole section. After the humanoid robot base plate 100 is assembled with the sole 200, the rod portion of the protrusion passes through the first hole section, and the expansion portion is limited in the second hole section due to the size being larger than the hole diameter of the first hole section. Since the humanoid robot base plate 100 is made of an elastic material, the first hole section can elastically deform during assembly to allow the expansion portion to pass through, and restore to its original shape after the expansion portion completely enters the second hole section. Thus, the expansion portion forms a surface contact with the inner wall of the second hole section, limiting the axial movement of the humanoid robot base plate 100, while the stepped change in hole diameter generates a support force perpendicular to the axial direction, preventing the humanoid robot base plate 100 from shifting when subjected to lateral force, and can limit the humanoid robot base plate 100 from disengaging after the adhesive fails, further improving the structural stability and reliability of the humanoid robot base plate 100.

[0044] In an embodiment of the present application, the limiting structure 30 is a limiting column (not shown), which is inserted into the groove of the robot sole 200.

[0045] It can be understood that the limiting column can refer to a columnar protruding structure, which can specifically adopt a cylindrical or prismatic form, and the material can be consistent with the overall material of the humanoid robot base plate 100, adopting a plastic material with certain elasticity and flexibility; or the material can be inconsistent with that of the humanoid robot base plate 100, adopting a material with higher strength than the main body of the humanoid robot base plate 100. The structure forms spatial complementarity with the groove of the sole 200 through geometric shape, and can generate mechanical constraint during insertion. The groove can refer to a recess structure provided on the robot sole 200, the inner contour of which matches the outer surface of the limiting column, and the depth of the groove can be set to completely accommodate the insertion of the limiting column and form a support surface at the bottom.

[0046] Specifically, the insertion and cooperation of the limiting column and the groove can form a three-dimensional spatial constraint. When the humanoid robot base plate 100 is subjected to the load generated by the movement of the robot, the side wall of the limiting column contacts the inner wall of the groove to generate friction, and the end face of the column body contacts the bottom face of the groove to generate axial constraint, so that the humanoid robot base plate 100 and the robot sole 200 can form a shear-resistant structure through the geometric interfitting. Under the action of lateral load, the contact area of the limiting column and the groove extends along the load direction, and the load is dispersed to the contact area of the column body and the groove, avoiding stress concentration to cause the connection between the humanoid robot base plate 100 and the sole 200 to fail, so that the humanoid robot base plate 100 can be more stably assembled on the robot sole 200, further improving the practicability and structural reliability of the humanoid robot base plate 100.

[0047] Referring to Figure 1 And Figure 2 In an embodiment of the present application, the anti-skid structure 50 comprises a plurality of protrusions 51, which are arranged in intervals on the second surface 10b.

[0048] In the embodiment, the protrusion 51 can refer to a three-dimensional structure vertically extending from the second surface 10b of the humanoid robot base plate 100, which can be realized by regular cylinders, prisms and other structures, of course, it can also be realized by irregular block structures, and the present application does not limit the structure and shape of the protrusion 51.

[0049] By arranging the protrusions 51 in intervals to form discrete contact points, the friction can be increased by increasing the local pressure, when the humanoid robot base plate 100 is in contact with the ground, the top of the protrusion 51 deforms first to adapt to the micro profile of the ground, forming multi-point dynamic occlusion, so that the humanoid robot base plate 100 can achieve better anti-skid effect, effectively preventing the robot from slipping when walking. And the arrangement gap of the protrusion 51 can form an air flow channel when under pressure, reducing the moving resistance caused by negative pressure adsorption effect, so as to better reduce the moving load of the robot, reduce the energy consumption of the robot, and further improve the practicability and reliability of the humanoid robot base plate 100.

[0050] And when the limiting structure 30 is designed with a limiting hole 31 penetrating through the first surface 10a and the second surface 10b, the protrusion with a certain height can make the second surface 10b a certain height from the ground, which is beneficial to better avoid the friction between the structure of the robot foot bottom 200 and the limiting structure 30 and the ground, better reduce the wear of the robot foot bottom 200, and further improve the protection effect of the humanoid robot base plate 100.

[0051] Further, in an embodiment of the present application, the side of the protrusion 51 opposite to the second surface 10b is arc-shaped at the connection with the peripheral side of the protrusion 51.

[0052] In the embodiment, the arc-shaped setting of the edge of the protrusion 51 can refer to the continuous curved transition structure formed between the top edge and the side of the protrusion 51, which can be realized by chamfering process or curved surface forming process, which can eliminate the stress concentration point at the right angle connection, which is beneficial to reduce the risk of fracture of the root of the protrusion 51 caused by excessive local stress, when the protrusion 51 is in contact with the ground, the arc-shaped transition structure of the top edge can avoid the stress concentration phenomenon caused by the traditional right angle connection under pressure, thereby reducing the wear or cracking of the edge of the protrusion 51, and further improving the structural stability and reliability of the humanoid robot base plate 100.

[0053] Referring to Figure 2In an embodiment of the present application, the side of the protruding block 51 opposite to the second surface 10b is provided with a plurality of protruding point structures 53.

[0054] In the embodiment, the protruding point structure 53 can refer to a tiny protrusion distributed on the top surface of the protruding block 51, which can be formed by mold forming or surface etching process. The protruding point structure 53 can be embodied in the shape of a regular cylinder, a prism, a sphere, etc. Of course, it can also be embodied in the shape of an irregular block. The shape of the protruding point structure 53 is not limited in the present application. By increasing the microscopic contact points on the top surface of the protruding block 51, the contact pressure of the protruding block 51 can be dispersed, and the surface friction coefficient of the protruding block 51 can be increased, so that the humanoid robot base plate 100 can achieve better anti-skid performance, and the anti-skid structure 50 can maintain stable grip force under complex ground conditions, further improving the structural stability and reliability of the humanoid robot base plate 100.

[0055] Referring to Figure 4 , Figure 7 and Figure 8 In an embodiment of the present application, the humanoid robot base plate 100 further comprises a fixing member 15, which is used to connect the humanoid robot base plate 100 and the robot foot bottom 200.

[0056] In the embodiment, the fixing member 15 can refer to a physical connection member 13 independent of the adhesive. Specifically, it can be implemented by using detachable fasteners such as bolts, latches, buckles, etc. By using the fixing member 15, the physical constraint between the humanoid robot base plate 100 and the robot foot bottom 200 can be directly established by rigid locking, and the lateral load generated during movement can be borne, thereby better improving the connection stability and reliability of the humanoid robot base plate 100 and the robot foot bottom 200.

[0057] The humanoid robot base plate 100 can be connected to the robot foot bottom 200 only by the fixing member 15. In combination with the cooperation of the limiting structure 30 on the first surface 10a and the foot bottom 200, and the increased frictional force between the rough texture on the first surface 10a and the surface of the foot bottom 200, the geometric constraint between the humanoid robot base plate 100 and the foot bottom 200 can be better formed, and the humanoid robot base plate 100 can be effectively prevented from being separated from the foot bottom 200. In addition, the first surface 10a and the robot foot bottom 200 can be bonded by using the adhesive, and the humanoid robot base plate 100 and the foot bottom 200 can be connected by using the fixing member 15. This is conducive to reducing the stress concentration of the adhesive layer and reducing the risk of cracking failure of the adhesive layer under the transverse load constraint of the humanoid robot base plate 100 and the foot bottom 200 by the fixing member 15 and the limiting structure 30, thereby improving the connection stability and reliability of the humanoid robot base plate 100 and the foot bottom 200, and significantly prolonging the effective service life of the humanoid robot base plate 100.

[0058] It should be noted that the fixing member 15 can be inserted into the foot bottom 200 through the humanoid robot bottom plate 100 by means of a screw or a bolt, and fastened by pressing the second surface 10b of the humanoid robot bottom plate 100 with a nut; or the fixing member 15 can adopt a buckle structure to fasten the humanoid robot bottom plate 100 and the sidewall of the foot bottom 200; there are many ways for the fixing member 15 to connect the humanoid robot bottom plate 100 and the foot bottom 200, which are not limited in the present application.

[0059] Referring to Figure 4 , Figure 7 and Figure 8 , in an embodiment of the present application, the humanoid robot bottom plate 100 comprises a main body part 11 and a connecting part 13, the main body part 11 is provided with a limiting structure 30; the connecting part 13 is connected to the main body part 11, the tensile property of the connecting part 13 is greater than that of the main body part 11, and the fixing member 15 is connected to the connecting part 13.

[0060] It can be understood that the main body part 11 can refer to the area that constitutes the basic structure of the humanoid robot bottom plate 100, which can be realized by rubber or plastic materials, and has the functions of contact connection and anti-skid between the humanoid robot bottom plate 100 and the foot bottom 200; while the connecting part 13 can refer to the reinforced area connected to the main body part 11, which can be realized by metal inserts, fiber reinforced composites or thickened structures, and has the function of bearing the tensile force transmitted by the fixing member 15. By selecting materials or optimizing the structure to make the tensile property of the connecting part 13 higher than that of the main body part 11, the humanoid robot bottom plate 100 can form a gradient distribution of mechanical properties. The difference in tensile property refers to the difference in the ability to resist tensile fracture between the connecting part 13 and the main body part 11, which can be realized by material compounding, embedded reinforcing ribs or local thickening, so that the connecting part 13 becomes the core area of tensile force bearing.

[0061] In this way, the design of the main body part 11 and the connecting part 13 with differentiated properties can make the humanoid robot bottom plate 100 have better wear resistance, anti-skid and shock absorption performance, and at the same time, the connecting part 13 can better bear the tensile force applied by the rigid fixing member 15, so that the humanoid robot bottom plate 100 can be more stably assembled on the robot foot bottom 200 by the fixing member 15, better prevent the humanoid robot bottom plate 100 from falling off, and further improve the practicality and structural reliability of the humanoid robot bottom plate 100.

[0062] Further, in an embodiment of the present application, the main body part 11 and the connecting part 13 are integrally formed.

[0063] In the embodiment, the main body part 11 and the connecting part 13 can be formed into a seamless whole structure through a whole machining process, and can be realized by using an injection molding or die casting process, so as to eliminate the connection weakness of the split connection structure, so that the humanoid robot base plate 100 can realize better overall structural stability, so that the humanoid robot base plate 100 can better utilize the overall structure main body part 11 to realize the required anti-skid, wear-resistant, shock-absorbing and other performances, while guaranteeing the fastening connection effect of the fixing part 15 on the humanoid robot base plate 100 and the foot bottom 200, and further improving the structural stability and reliability of the humanoid robot base plate 100.

[0064] The above is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
