Description

Technical Field

[0001] The invention relates to the technical field of robot toys, in particular to a small modular robot rotary joint model. Background Art

[0002] With the rapid development and wide application of robot technology, robots have received widespread attention from the whole society and aroused great interest among people. Robot education has also received more and more attention. On the one hand, various colleges and universities have set up robot engineering majors, purchased various robot platforms, and carried out robot adult education; on the other hand, robot education has also begun to move towards younger age, through the establishment of various interest classes and small robot competitions, to provide robot education for children and teenagers, and through the robot toy, the robot is taught in an entertaining way. Children and teenagers need suitable robot teaching aids. At present, some robot toys and small robot kits are commonly used, the most typical of which is the Lego model. However, the existing robot kits and Lego models are actually too different from the actual robots in terms of appearance and configuration. There is still a long way to go from the concept and technology of robots, and it is difficult to meet the actual needs of children and teenagers for robot education.

[0003] An important development direction of robotics is modularization, which means dividing the robot into modules for unit design, designing the robot joint or end effector into an independent and complete electromechanical unit with certain functions, and building a robot system of various forms and functions through the combination and connection between modules; in other words, modular robots can change the degree of freedom and configuration by adding or removing modules and their different combinations, so as to meet the needs of multi-task, wide application and high flexibility. Modular design facilitates large-scale and standardized production, reduces production and maintenance costs, and therefore has received widespread attention. A series of robot joint modules have been developed at home and abroad. For example, ZL201010242196.7 and ZL201010242208.6 disclose a swing joint and a rotary joint module respectively. These joint modules have good performance, can meet certain requirements, and can also be used in robot scientific research and adult education.

[0004] Modular reconfigurable robots are very suitable for robot innovation education because they can be derived into a variety of robot systems. They are also very interesting because of their variable configurations and degrees of freedom. However, existing real robot modules and modular robots are not suitable for children's education because of their high technical requirements, complex structures, difficult use, high costs, large size and weight.

[0005] In view of this, in view of the shortcomings of current robot toys and models, and the incompatibility of existing robot modules in children's education, the present invention combines the modularization and toyization of robots, and discloses a small modular robot rotary joint model. The rotary joint model can be connected with other models with the same interface in sequence to form a robot model, which can be used as a robot toy, a robot configuration teaching aid, or an ornamental gift. Summary of the invention

[0006] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a small modular robot rotary joint model that can be connected to other functional module models with the same adapters through first and second adapters at both ends to form a variety of robot models.

[0011] The upper and lower ends of the complete shell are open, and the first and second adapters are respectively installed at the openings at the upper and lower ends of the complete shell, and perform rotational motion relative to the complete shell.

[0012] Furthermore, the concave circular hole and the convex circular cylinder are located at opposite positions on two opposite side walls of the same shell.

[0013] Furthermore, the first and second adapters are both three-layer structures, and the cross-section forms an "I" shape; the upper and lower bosses constitute a rotating pair to achieve relative rotation; the first and second adapters are provided with axle mounting holes at the bottom for the installation of the axles; the side is provided with circumferential fixing bayonet; the top is provided with grooves and protrusions of equal size and spacing to allow seamless docking between the adapters, and the connection of the interfaces between the modules is achieved through the limiting effect.

[0014] Furthermore, the complete shell is provided with grooves and positioning bosses at the upper and lower openings, the upper and lower bosses of the first and second adapters are respectively placed in the grooves of the corresponding openings, and the positioning bosses are clamped between the upper and lower bosses.

[0015] Furthermore, after the left and right shells and the first and second adapters are assembled, they are connected to other models with the same interface through the first and second adapters to form a variety of robot models.
