[0002] In recent years, with the rapid development of artificial intelligence, robotics and human-computer interaction, humanoid robots, as intelligent devices with human form and movement capabilities, are being widely used in various scenarios such as medical assistance, service robots and rehabilitation training. As one of the key components of humanoid robots, the functionality, modularity and human-machine adaptability of the robotic arm have become one of the key directions of current research and product development.

[0003] Existing humanoid robot arms mostly adopt an integral structure with finger components molded as a single piece, resulting in high maintenance and replacement costs, poor flexibility, and difficulty in meeting personalized needs. In addition, traditional products are usually designed with fixed functions and limited functionality, making it difficult for users to replace parts or expand functions according to specific needs, thus limiting their application scope and user experience.

[0004] Meanwhile, with the increasing market demand for rehabilitation aids and high-performance bionic systems, modular prosthetic structures with higher customization, more convenient maintenance, and lower manufacturing costs have gradually become a research hotspot. Currently, there is still a lack of an arm prosthetic structure that can achieve finger-level hot-swappable, customizable shape and function, and has both high degree of freedom and easy maintenance. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a finger module that supports hot-drawing, aiming to improve the problem that existing humanoid robot arms mostly adopt an integral structure with the finger components molded as a single piece, resulting in high maintenance and replacement costs, poor flexibility, and difficulty in meeting personalized needs.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see the appendix Figure 1 - Appendix Figure 3 An embodiment of this utility model provides a finger module that supports hot drawing, including a structural shell 2, a structural shell 15 fixedly connected to the top of the structural shell 2, an elastic joint connector 4 rotatably connected to the left side of the structural shell 15, a finger structure 1 rotatably connected to the outer wall of the elastic joint connector 4, a steel cable 5 provided on the inner side of the finger structure 1, a module main control board 12 fixedly connected to the bottom inner side of the finger structure 1, an elastic brush 9 fixedly fixed to the top front side of the module main control board 12, a micro motor 11 fixedly connected to the inner right side of the structural shell 2, a lead screw 16 fixedly connected to the output end of the micro motor 11, a threaded slider 8 threadedly connected to the outer wall of the lead screw 16, a steel cable pulley 7 provided on the top rear side of the threaded slider 8, and an FPC cable 13 provided in the middle of the bottom inner side of the structural shell 2.

[0030] Specifically, the steel cable is fixed inside the structural housing 2 by the steel cable fixing screw 26, and then fixed on the threaded slider 8 by the steel cable pulley 7. The elastic brush 9 is built into the threaded slider 8, so that the slider is grounded and connected to the contacts on the module main control board 12. The receiver or other connectors are connected to the module. In the working state, the receiver and connectors supply power to the module and send commands, which reach the module main control board 12 through the communication circuit board 14.

[0031] Please see the appendix Figure 3 - Appendix Figure 5 A U-shaped plate 17 is fixedly connected to the bottom right side of the inner side of the structural shell 12. The inner side of the U-shaped plate 17 is fixedly connected to the outer wall of the micro motor 11. A communication circuit board 14 is fixedly connected to the right side of the structural shell 12. A support bearing 10 is fixedly connected to the other end of the lead screw 16.

[0032] Specifically, the outer shell 12 contains a supporting bearing 10, a lead screw 16, and a micro motor 11 for controlling the movement of the slider. The main control board 12 and the communication circuit board 14 are connected by an FPC cable 13, and together with the outer shell 2 15, they form an outer shell.

[0033] Please see the appendix Figure 5 - Appendix Figure 7 The adjacent direct threaded connections of structural shell 1 2 and structural shell 2 15 are provided with steel cable fixing screw 2 6, and the bottom front and rear sides of finger structure 1 are both threaded with steel cable fixing screw 1 3.

[0034] Specifically, the cable fixing screw 26 is a high-strength fastener specifically designed for securing the cable 5 or connecting components. It is typically made of high-strength alloy steel with a special rust-proof and wear-resistant surface treatment to ensure it will not be damaged by environmental factors or frequent stress during long-term use. During installation, threaded holes matching the cable fixing screw 26 are pre-drilled at the adjacent connection points of structural housing 12 and structural housing 25.

[0035] Working principle: The basic mechanical structure is formed by connecting the finger structure 1 and the outer shell 2 with the elastic joint connector 4. The end of the finger structure 1 is fixed with a steel cable 5 by a steel cable fixing screw 3. The steel cable 5 passes through the entire basic mechanical structure and around the steel cable pulley 7. It is then fixed inside the outer shell 2 by a steel cable fixing screw 6, and then fixed to the threaded slider 8 with the steel cable pulley 7. The elastic brush 9 is built into the threaded slider 8, so that the slider is grounded and connected to the contacts on the main control board 12 of the module. The outer shell 2 also contains a support bearing 10, a lead screw 16, and a micro motor 11 to control the movement of the slider. The main control board 12 of the module and the communication circuit board 14 are connected by an FPC cable 13. The outer shell 2 15 and the outer shell 2 form the outer shell. The receiver or other connectors are connected to the module. In operation, the receiver and connector power the module and send commands, which reach the module's main control board 12 via the communication circuit board 14. At this time, the module's main control board 12 determines the position of the slider based on the current conductive contact position and compares it with the received command. Then, the micro motor 11 is activated to make the lead screw 16 drive the slider to move to the target position. In conjunction with the sliding of the steel cable 5 on the threaded slider 8, the steel cable 5 is pulled, thereby pulling the basic mechanical structure to achieve flexion and extension movements. Thus, a modular hot-swappable design at the single-finger level is realized. Users can quickly disassemble, replace, and upgrade a single finger module without complicated operations or professional tools, greatly improving the maintenance efficiency and ease of use of the prosthesis. In addition, users can freely configure the shape, functional modules, and control scheme of the prosthesis according to different application scenarios and individual needs, thereby achieving personalized adaptation and functional expansion.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
