[0046] like Figures 1 to 3 As shown, the robot hip joint structure 100 according to an embodiment of the present invention includes a hip base 10 , a waist yaw joint module 50 , a hip yaw joint module 20 and a hip lateral swing joint module 30 .

[0047] Specifically, a mounting cavity is provided in the hip base 10. The hip yaw joint module 20 is detachably provided in the mounting cavity, and the waist yaw joint module 50 is integrated with the hip base 10 and the waist support 11 in the middle of the mounting cavity.

[0048] In other words, see Figures 1 to 3 The robot hip joint structure 100 is mainly composed of a hip base 10, a hip yaw joint module 20 and a hip lateral swing joint module 30. Among them, a mounting cavity is provided in the hip base 10. The waist yaw joint module 50 can be integrated with the hip base 10 and the waist support 11 in the middle of the mounting cavity. The hip yaw joint module 20 is detachably arranged at the front side of the mounting cavity, and the hip yaw joint module 20 extends along a first direction relative to the hip base 10. The first direction can be understood as the height direction of the robot. The hip lateral swing joint module 30 is integrated with the hip yaw joint module 20 in the hip base 10 to ensure that the robot hip joint structure 100 is more compact. The hip lateral swing joint module 30 is arranged at the rear side of the mounting cavity, and the hip lateral swing joint module 30 extends along a second direction relative to the hip base 10. The second direction can be understood as the horizontal direction of the robot.

[0049] The hip yaw joint module 20 and the hip lateral swing joint module 30 are each integrated with mounting interfaces 40 on the side facing the hip base 10. These integrated mounting interfaces 40 allow for connection to other joint structures of the robot, eliminating the need for intermediate adapters. This simplifies the overall connection method, effectively reduces joint weight, and ensures a more integrated and unified robotic hip joint structure 100, facilitating installation and improving reliability. The present robotic hip joint structure 100 effectively addresses the existing challenges of heavy-duty, lightweight, and integrated hip joint designs in pedestrian robots.

[0050] Thus, according to the robot hip joint structure 100 of the embodiment of the present invention, the hip yaw joint module 20 and the hip yaw joint module 20 are integrated into the hip base 10, ensuring that the robot hip joint structure 100 is more compact. At the same time, by integrating the mounting interface 40 on the hip yaw joint module 20 and the hip yaw joint module 20, there is no need for an intermediate adapter, which simplifies the overall connection method, effectively reduces the weight of the joint, and ensures that the robot hip joint structure 100 is more integrated, which can facilitate installation and improve reliability.

[0052] That is to say, if Figure 1 and Figure 2 As shown, the hip yaw joint module 20 and the hip lateral swing joint module 30 are each configured as a columnar structure, achieving a simple axis system design. The hip yaw joint module 20 and the hip lateral swing joint module 30 can each independently rotate along their axis, achieving effective movement of the robotic hip joint structure 100.

[0055] In other words, Figure 1 and Figure 2As shown, the hip yaw joint module 20 is mainly composed of a hip yaw actuator 21, a hip yaw joint 22 and a hip yaw torque sensor 23. Among them, the housing of the hip yaw actuator 21 is integrated with a mounting interface 40, which does not require the use of an intermediate adapter, simplifies the overall connection method, effectively reduces the weight of the joint, and ensures that the robot hip joint structure 100 is more integrated, which is both convenient for installation and improves reliability. The hip yaw joint 22 is detachably connected to the hip yaw actuator 21, and the hip yaw actuator 21 can control the movement of the hip yaw joint 22. The hip yaw torque sensor 23 is arranged on the side of the hip yaw joint 22 that is away from the hip yaw actuator 21. By arranging the hip yaw torque sensor 23, the movement accuracy of the hip yaw joint 22 can be effectively achieved.

[0056] According to one embodiment of the present invention, the hip lateral swing joint module 30 includes a hip rotation actuator 31 , a hip rotation joint 32 and a hip rotation torque sensor 33 .

[0057] Specifically, a mounting interface 40 is integrated on the housing of the hip rotation actuator 31 . The hip rotation joint 32 is detachably connected to the hip rotation actuator 31 . The hip rotation torque sensor 33 is disposed on a side of the hip rotation joint 32 facing away from the hip rotation actuator 31 .

[0058] In other words, Figures 1 to 3 As shown, the hip lateral swing joint module 30 is mainly composed of a hip rotation actuator 31, a hip rotation joint 32 and a hip rotation torque sensor 33. Among them, the housing of the hip rotation actuator 31 is integrated with a mounting interface 40, which does not require the use of an intermediate adapter, simplifies the overall connection method, effectively reduces the weight of the joint, and ensures that the robot hip joint structure 100 is more integrated, which is convenient for installation and improves reliability. The hip rotation joint 32 is detachably connected to the hip rotation actuator 31, and the hip rotation actuator 31 can control the movement of the hip rotation joint 32. The hip rotation torque sensor 33 is arranged on the side of the hip rotation joint 32 that is away from the hip rotation actuator 31. By arranging the hip rotation torque sensor 33, the movement accuracy of the hip rotation joint 32 can be effectively achieved.

[0059] According to one embodiment of the present invention, Figures 1 to 3 As shown, the axes of the hip yaw joint module 20 and the hip lateral swing joint module 30 are perpendicular to each other, ensuring that the hip yaw joint module 20 and the hip lateral swing joint module 30 can correspond to the movement direction of the human body, thereby facilitating the human-like movement of the robot hip joint structure 100.

[0060] According to one embodiment of the present invention, a waist yaw joint module 50 is provided on a side of the hip base 10 facing away from the hip yaw joint module 20 and the hip lateral swing joint module 30 .

[0061] That is to say, if Figure 1 and Figure 2 As shown, a lumbar yaw joint module 50 is installed within the hip base 10. The lumbar yaw joint module 50 is located on the side of the hip base 10 facing away from the hip yaw joint module 20 and the hip lateral swing joint module 30. The lumbar yaw joint module 50 is integrated with the hip base 10 and the lumbar support 11 within the center of the mounting cavity. By integrating the lumbar yaw joint module 50 within the hip base 10, a more integrated design is achieved for the robot hip joint structure 100, simplifying the structure while reducing the space and weight occupied by the robot hip joint structure 100.

[0062] According to an embodiment of the present invention, there are two hip yaw joint modules 20 and two hip lateral swing joint modules 30 , and each hip yaw joint module 20 corresponds to one hip lateral swing joint module 30 .

[0063] In other words, see Figure 3 The hip yaw joint module 20 and the hip lateral swing joint module 30 together constitute four joint structures. Each hip yaw joint module 20 corresponds to a hip lateral swing joint module 30. The four joint structures and the waist yaw joint module 50 are integrated into the hip base 10 and adopt a detachable installation method, which is convenient for disassembly and assembly while ensuring that the robot hip joint structure 100 is more compact as a whole, which is convenient for miniaturization and lightweight design.

[0064] According to one embodiment of the present invention, Figure 3 As shown, the robot hip joint structure 100 also includes a driver module 61, which is installed in the mounting cavity of the hip base 10. The driver module 61 can drive the movement of the hip yaw joint module 20 and the hip lateral swing joint module 30. The modular design of the driver structure greatly improves the maintainability of the robot.

[0065] According to one embodiment of the present invention, Figure 3 As shown, the robot hip joint structure 100 also includes an inertial measurement unit 62 and a heat sink module 63. The inertial measurement unit 62 is mounted on the waist support 11. The heat sink module 63 is housed within the mounting cavity of the hip base 10 and is arranged side by side with the driver module 61. The modular design of the heat dissipation structure effectively improves the robot's maintainability.

[0066] In summary, according to the embodiment of the present invention, the robot hip joint structure 100 integrates the hip yaw joint module 20 and the hip yaw joint module 20 into the hip base 10, ensuring that the robot hip joint structure 100 is more compact. At the same time, by integrating the mounting interface 40 on the hip yaw joint module 20 and the hip yaw joint module 20, there is no need to use an intermediate adapter, which simplifies the overall connection method, effectively reduces the weight of the joint, and ensures that the robot hip joint structure 100 is more integrated, which can facilitate installation and improve reliability.
