Problems solved by technology
Now even if some clothes mannequin robots are made into a structure with a certain degree of freedom in the joints that can realize multi-pose display, this kind of clothes mannequin robot often has defects such as a small number of degrees of freedom that can be realized, and a small range of motion for each degree of freedom. The most important thing is that the driving of the joints can only be done manually, and there is no clothing mannequin robot with joints actively driven on the market.

[0010] The two-degree-of-freedom active elbow joint of a clothes mannequin robot disclosed by the present invention mainly realizes the functions of connecting the upper arm and the forearm and transmitting the movement of the upper arm to the forearm; the active driving of the elbow joint realizes the two rotational degrees of freedom. The specific implementation of each function is as follows:
[0011] The implementation of the movement of the upper arm transmitted by the elbow joint: the movement of the upper arm is transmitted to the elbow joint through the upper arm bone, and then to the forearm. The upper arm skeleton is fixedly connected to the steering gear base of the No. 1 steering gear assembly through four bolts. The steering gear base is designed according to the shape parameters of the steering gear. The steering gear and the steering gear base are fixedly connected. The No. 1 steering gear The component is fixedly connected to the L-shaped plate through four bo...

The invention discloses a two-degree-of-freedom active elbow joint structure and a driving device of a clothing model robot, and which are used for realizing anticipant-degree-of-freedom motions of forearms of the robot to realize automatic showing of clothes in all directions and all angles through a clothing model. The elbow joint mainly realizes two functions: one is to connect big arms with the forearms, and the other one is to realize the needed-degree-of-freedom joint driving. The elbow joint can realize two degrees of freedom of rotation: lifting of the forearms and rotation of the forearms by surrounding axles of the big arms; and the two degrees of freedom of rotation are respectively driven by two steering engines. The steering engine for driving the degree of freedom of lifting the forearms directly drives joint shafts for connecting the big arms with the forearms; and the steering engine for driving the degree of freedom of rotating the forearms by surrounding the axles of the big arms is mounted at the tail ends of the big arms, and drives the forearms, the joint shafts, the steering engine for driving the joint shafts and the connected part thereof to rotate by surrounding the axles of the big arms. The structure is compact and reliable, and can be applied to various service robots and mechanical arm serial connecting structures needing to realize two degrees of freedom of rotation.
Description
(1) Technical field [0001] The invention relates to a clothes mannequin robot system, in particular to an active drive system for series mechanical arm joints. (2) Background technology [0002] Most of the current clothing model robots can only achieve a static display of a fixed posture, which is to make the clothing models into a fixed structure of different postures, and choose different postures of clothing models according to the angles that need to be displayed. Now even if some clothes mannequin robots are made into a structure with a certain degree of freedom in the joints that can realize multi-pose display, this kind of clothes mannequin robot often has defects such as a small number of degrees of freedom that can be realized, and a small range of motion for each degree of freedom. The most important thing is that the drive of the joints can only be done manually, and there is no clothes mannequin robot with joints actively driven on the market. (3) Contents of ...
