Embodiment 1

[0028] like figure 2 As shown, an ultrasonic levitation toy car mainly includes a rectangular frame 1 and a toy car shell 2 . like image 3 As shown, the inside and outside of both ends of the rectangular frame 1 are pasted with piezoelectric ceramic sheets 3, the rectangular frame 1 is installed in the toy car shell 2, and its two ends are fixed in the toy car shell 2, the rectangular frame 1. The bottom is flush with the bottom plate of the toy car shell 2, so that an extruded air film can be formed between the bottom plate of the car and the ground. Four pieces of piezoelectric ceramics 3 are bonded to the inner and outer sides of the rectangular frame 1 by epoxy resin A-B glue. On the end face, the total weight of the toy car is about 40g.

[0029] like Figure 4 As shown, the positive and negative electrodes of the piezoelectric ceramic sheet 3 are arranged on the same side, and the other side is pasted on the rectangular frame 1 . A sinusoidal alternating current si...

Embodiment 2

[0032] Image 6As shown, the working principle of the toy car in this embodiment is generally the same as that of Case 1. The difference is that in this embodiment, the aluminum frame 1 in Embodiment 1 is changed to a flat plate 7, and the bottom of the toy car shell 2 is evenly distributed. A flat plate 7, the flat plate 7 is connected to the bottom plate of the toy car housing 2 through a spring 6 with a large elastic coefficient, the spring 6 is located at the center of the flat plate 7, and the upper surface of each flat plate 7 is pasted with a piezoelectric ceramic sheet by epoxy resin 51, 52, 53, 54, through the input of sinusoidal alternating current signals in the piezoelectric ceramic sheets 51, 52, 53, 54, the piezoelectric ceramic sheets vibrate along the thickness direction, further driving the vibration of the flat plate, between the flat plate 7 and the ground A thin film of squeezed air is formed to generate a squeeze force, thereby making the toy car levitate....

Abstract

The invention discloses an ultrasonic levitation toy car, which mainly consists of a rectangular frame, a toy car casing and piezoelectric ceramic pieces, wherein the piezoelectric ceramic pieces are bonded on the inner and outer side surfaces of the two ends of the rectangular frame, the rectangular frame is arranged in the toy car casing, in addition, the two ends of the rectangular frame are fixed in the toy car casing, and the bottom end of the rectangular frame is aligned with a bottom plate of the toy car casing. The piezoelectric ceramic pieces generate simple harmonic vibration at certain frequency through sinusoidal alternating current excitation, upper and lower flat plates of the rectangular frame are driven to vibrate, and the rectangular frame is driven to vibrate, so that an extrusion air film is formed between the toy car bottom plate and the ground, the extrusion force is generated, and the toy car realizes the levitation. The ultrasonic levitation toy car provided by the invention has the advantages that the structure is simple, the service life of the toy car is prolonged, the hand operation ability of a child can be trained, and certain enlightenment effects are achieved on the child intelligence development and the acquaintance on natural science.

Description

technical field [0001] The invention relates to an ultrasonic levitation toy car, specifically, it is a toy car invented by using ultrasonic near-field levitation technology, which plays a certain enlightening role in children's intelligence development and understanding of natural science . Background technique [0002] With the rapid development and combination of electronic technology, sensor technology, computer technology, automatic control technology, artificial intelligence and mechanical technology, the toy industry is developing rapidly. The market share of traditional toys is gradually declining, while electronic toys with high-tech content are gradually increasing. Smart toys have become the development trend of modern toys. Although my country is a big toy-producing country, there is still a certain gap between China and foreign countries in the development of high-tech smart toys. Therefore, research on smart toy technology, on the one hand, has certain practi...
