A method and device for realizing single-degree-of-freedom compound cross swing

Abstract

The present invention relates to a single-degree-of-freedom compound cross swing method and device, the device includes a drive motor, a radial joint bearing assembly and an actuator ten-byte, the output shaft of the drive motor and the radial joint bearing assembly are installed at an angle of inclination to Execute on ten bytes. The present invention connects the crank with the centripetal bearing and the shaft hole that performs ten-point inclination at a certain angle, omitting the joint bearing and connecting rod in the middle, and saving the longitudinal occupied space of the whole mechanism. Change the distance between the drive motor shaft installation hole on the radial bearing crank and the execution ten-section shaft installation hole or the installation height of the twentieth-section shaft on the motor seat to adjust the angle of the compound cross swing. Both the radial spherical plain bearing assembly and the execution ten-piece are machined parts, so there is no need to worry about the adjustment during installation beyond the range of movement of the ten-piece. At the same time, the drive motor is directly installed and fixed on the execution ten-piece, which saves the vertical occupied space of the whole mechanism, and is conducive to adapting to the narrow installation space in the bionic organism.

Description

technical field [0001] The invention relates to the technical field of bionic performance of amusement facilities, in particular to a method and a device for compound cross swinging with a single degree of freedom realized by circular rotation. A typical example of the implementation of this method is to simulate a single-degree-of-freedom shaking movement of a human, such as the Korean hat dance. Background technique [0002] In the field of amusement ride bionic performance technology, compound cross swings are usually used to express the swinging motion of vertebrates. At present, there are generally two methods used to realize compound cross swing: [0003] One is to use two motors to independently drive the two joints of the ten-byte to realize the compound cross swing. The disadvantage is that the structure is complex and takes up a lot of space and requires two motors. There is not enough installation space in the bionic organism, and the single degree of freedom is ...

Problems solved by technology

[0003] One is to use two motors to independently drive two ten-byte joints to achieve compound cross swing. The disadvantage is that the structure is complex and takes up a lot of space and two motors are needed. There is not enough installation space in the bionic organism, and the single degree of freedom The multi-motor drive of the action increases the difficulty of control and wastes resources, etc.

For example, the utility model patent with the authorized announcement number of CN206355589 discloses a driving mechanism for bionic animal eyes. The two joints of the joint are used to realize the compound cross swing scheme. It can be seen from the specific scheme that there are problems such as complex structure, relatively large space occupation, two motors are required, difficulty in driving control, and waste of resources;

[0004] One is driven by a single motor, and the crank and ten joints are connected by a set of joint bearings and connecting rods. The disadvantage is that the entire mechanism space is elongated in the longitudinal direction, and the angle of the compound cross swing has a special effect on the length of the connecting rod. Sensitive, with a little adjustment, it is very likely to reach the maximum range of movement of ten bytes, and there will be a stuck problem
