Bead bouncing device

Abstract

The invention relates to a bead bouncing device. The bead bouncing device comprises a bead, a swing frame, a bouncing compensation mechanism and a swing compensation mechanism, wherein the swing frame has a support, a swing member doing reciprocating swing at a period and swing amplitude identical to bead bounce, and a bearing member arranged on the swing member, the bearing member has a rigid bearing surface forming a bead falling region, the falling region is a concave curved surface formed through molding, a normal inclination angle of a contact contacting the bead each time makes the bead generate a reverse direction horizontal motion component, an absolute value of difference between displacement of the bead in a horizontal direction and a horizontal direction component of two-times swing amplitude of the bearing member is made to smaller than a dimension of the falling region in the horizontal direction, the bearing member is driven by the bouncing compensation mechanism to do reciprocating motion up and down with the period identical to bead bounce and contacts with the bead when the swing member reaches the swing amplitude, and the swing member is driven by the swing compensation mechanism at the swing period identical to the swing member. The bead bouncing device is advantaged in that the bead can be made to continuously bounce on the swinging bearing member, and people are made to have more interests in the bead bouncing device.

Description

technical field [0001] The invention relates to the technical field of exhibition and display, in particular to a small ball bouncing device. Background technique [0002] It is a relatively common phenomenon that the ball bounces on the carrier. Some stunt performers can show some objects bouncing up and down to a higher height in a small range through the control of their hands. Such performances show the actor's control skills and give the viewers a sense of novelty and wonder. In display occasions such as showcases and exhibitions, in order to attract the curiosity of the audience, it is also desirable to set up some dynamic display scenes, such as allowing the ball to bounce on a swinging carrier, which will be fresher, more interesting, and more arousing people's interest. Although theoretically speaking, as long as the swing period of the carrier is consistent with the design of the beating period of the ball, and the normal inclination of the contact point of the ca...

AI Technical Summary

Problems solved by technology

However, there are still many factors that are not involved in theoretical explanations, which will also affect the drop point of the ball, such as whether the quality of the ball is uniform, the flatness of the bearing surface of the bearing, and the compensation movement direction of the bearing. deviation factors etc.

The accumulation of these factors will make the ball gradually deviate from the carrier, which will lead to the failure of the demonstration
