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. figure 1 demonstrates the achievable degrees of freedom of a two-DOF active elbow joint, figure 1 The functional components represented by the reference numerals in are as follows: 1-1 is a shoulder, 1-2 is an elbow, and 1-3 is a wrist. Figure 4 It specifically shows the structure of the two-degree-of-freedom active elbow joint described in the present invention, Figure 4 The functional parts represented by the reference signs on the board are as follows: 1 is the arm bone, 2 is the forearm, 3 is the No. 2 steering gear assembly, 4 is the L-shaped plate, 5 is the No. 1 steering gear assembly, and 6 is the arm bone .

A two-degree-of-freedom active elbow joint structure and a drive system for a clothing model robot are used to realize the desired degree-of-freedom movement of the forearm of the robot, so as to realize the automatic display of clothes by the clothing model in all directions and from multiple angles. The elbow joint mainly realizes two functions, one is to connect the upper arm and the forearm, and the other is to realize the joint drive of the required degree of freedom. The elbow joint can realize two degrees of freedom of rotation, which are respectively lifting and lowering the forearm and rotation of the forearm around the axis of the boom, and the two degrees of freedom for rotation are respectively driven by two steering gears. Among them, the steering gear that drives the degree of freedom of raising and lowering the forearm directly drives the joint shaft connecting the upper arm and the forearm, and the steering gear that drives the degree of freedom of the forearm to rotate around the axis of the forearm is installed at the end of the forearm, driving the forearm, joint shaft It rotates around the axis of the boom together with the steering gear that drives the joint shaft and its connecting parts. The above-mentioned solution is compact and reliable, and can be used in various service robots and the structure of serial manipulators that need to realize two rotational degrees of freedom.
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 ...
