Electronic ultrasonic range finder child intelligence teaching aid

Abstract

The invention discloses an electronic ultrasonic range finder child intelligence teaching aid. The electronic ultrasonic range finder child intelligence teaching aid is characterized in that the PCB is provided with four connecting circular holes; the PCB is fixed by eight nylon columns; on the front face, nylon columns of which the top end is provided with a 6MM screw and with the diameter of 3MM, the length of 18MM penetrates through four circular holes in the edge of the PCB to be connected with the two-way nut thread nylon columns with the diameter of the back surface of 3MM and the lengthof 24mm; a circuit board is fixed in the center, the back double-pass 24MM nylon column connecting bottom plate is connected with a machine tooth screw with the diameter of 3MM; the tail end of the 18MM-lenght nylon column is connected and fastened with a 3MM machine tooth screw of the top plate; interface grooves with a specific shape are formed in the bottom plate; two long side plates and twoshort side plates are provided; the long side plates and the short side plates are directly clamped into the corresponding interface grooves in the bottom plate through the corresponding convex parts;the top plate is provided with interface grooves with a specific shape; the top plate is directly clamped into the corresponding convex parts of the long side plate and the short side plate through the corresponding interface grooves; the electronic ultrasonic range finder child intelligence teaching aid has the beneficial effects that the design principle is novel, the structure is unique, the debugging is convenient, the learning is integrated, the commercial prospect is very wide, the relevant technical blank can be filled up, and greater social benefits and economic benefits can be generated.

Description

technical field [0001] The invention relates to the field of electronic teaching aids, in particular to an electronic ultrasonic rangefinder educational teaching aid for children. Background technique [0002] Relying on a variety of electronic teaching aids, with the educational purpose of developing creative hands and creating brainstorming, the educational concept of innovation in thinking and creation in action is introduced to cultivate and develop children's abilities. The teaching mode of "thinking in music" is different from the traditional teaching method of quantifying children's evaluation with scores. [0003] At present, educational electronic teaching aids have single functions, fewer types, high packaging level, and the electronic devices are soldered on the circuit board, so students cannot manually plug and debug. However, there are few highly flexible and pluggable modular electronic teaching aids at present. . [0004] In order to solve technical bottlen...

AI Technical Summary

Problems solved by technology

[0003] At present, educational electronic teaching aids have single functions, fewer types, high packaging level, and the electronic devices are soldered on the circuit board, so students cannot manually plug and debug. However, there are few highly flexible and pluggable modular electronic teaching aids at present.

[0004] In order to solve technical bottlenecks such as relatively backward design level, difficult debugging, and poor training effect of the existing electronic teaching aids, the present invention discloses an electronic ultrasonic rangefinder children's educational teaching aid, which has low cost, novel scheme and unique configuration. , the principle is novel, the flexibility is high, the debugging time is short, and electronic devices can be assembled repeatedly on site, which can meet the actual needs of children's educational training, fill the gaps in related technologies, and produce greater social and economic benefits.
