Description

Technical Field

[0001] The utility model belongs to the technical field of teaching tools, and in particular relates to a dynamic balancer used for teaching demonstration. Background Art

[0002] In the teaching experiments of automatic control and other related courses, it is generally necessary to combine experimental equipment to explain the composition, structure, operation and actual effects of automatic control, so that students can have a more in-depth, comprehensive and specific understanding of the course content.

[0003] In the prior art, the left and right movement of a dynamic ball in a slide rail is achieved by achieving yaw, such as a direct-drive ball club teaching device disclosed in Chinese patent CN206236343U, which uses a motor to achieve the left and right swing of a connecting rod, thereby achieving the swing of a balancing mechanism. At that time, in this structure, since the balancing rod needs to swing, the limit block will be lower than the height of the connecting rod when it is vertical, so that when the balancing mechanism is in a horizontal state, the balancing mechanism is only supported by the connecting rod and has only one supporting point. This requires a high verticality between the balancing mechanism and the connecting rod during installation, and because the balancing mechanism has a certain length, it is difficult to process. Utility Model Content

[0005] To this end, the technical solution adopted by the utility model is: a dynamic balancer for teaching demonstration, including a transparent container extending left and right, a dynamic ball is arranged in the transparent container, the transparent container is arranged on a bottom plate through a left connecting component and a right connecting component arranged at intervals on the left and right, and the left connecting component and the right connecting component can realize the up and down movement of the left and right ends of the transparent container, thereby realizing the dynamic ball rolling left and right in the transparent container.

[0006] As a preferred embodiment of the above scheme, the transparent container includes a transparent cylinder and two connecting parts, the two connecting parts are spaced apart on the left and right sides of the transparent container, or the two connecting parts are correspondingly arranged on the left and right ends of the transparent cylinder, and the lower end of each connecting part is provided with a mounting ear for installation with a corresponding connecting component.

[0007] Further preferably, the left connecting component includes a left supporting seat arranged on the base plate, the upper end of the left supporting seat is hinged on the transparent container, and the right connecting component includes a first connecting rod, a second connecting rod and a driving assembly arranged on the base plate, one end of the first connecting rod can rotate under the action of the driving assembly, the other end of the first connecting rod is hinged on the second connecting rod, and the other end of the second connecting rod is hinged on the transparent container.

[0008] Further preferably, the left connecting component and the right connecting component have the same structure and are both configured as telescopic components, and the movement directions of the telescopic components on the left and right sides are opposite.

[0009] Beneficial effects of the utility model:

[0010] 1) The left-connected component and the right-connected component are used to realize the left-right movement of the dynamic ball in the transparent container. The overall structure is simple, which is conducive to the establishment of subsequent models and the research and implementation of control algorithms.

[0011] 2) Since the transparent container is supported by the left connecting component and the right connecting component, it has two supporting points, which makes it easy to achieve the stillness of the dynamic ball when not working, making the overall processing convenient.

[0016] To facilitate the dynamic ball 2 to roll left and right in the transparent container 1, the transparent container 1 includes a transparent cylinder 1a with at least one end being open on the left and right ends and two connecting pieces 1b. To facilitate the connection between the left and right connecting components and the transparent container, a mounting ear for mounting with the corresponding connecting component is provided at the lower end of each connecting piece.

[0017] The two connectors can be spaced apart on the left and right sides of the transparent container, and at least one of the two connectors is not arranged on the end of the transparent container. The connector arranged in the middle of the transparent container can be composed of two parts that are opposite to each other and have arc grooves, that is, fixed to the transparent container by a clamp.
