Description

Programmable building block motor module, building block assembly and design method

Technical Field

The invention relates to the technical field of design of electric drive integrated products, in particular to a programmable building block motor module structure, a building block assembly and a design method.

Background

The electronic building block organically combines the electronic technology and the building block, students can build and control models created by the electronic circuit or the computer program through activities designed by courses, and the students are trained to learn, exercise, infer, think, solve problems, create inventions, cooperate with teams and other abilities in the process of building the models actually, so as to develop the scientific field, logic analysis and program concept of the students, stimulate the scientific interest of the students, enrich the scientific teaching courses of schools and enable teaching to be lively and interesting.

In STEM (science, technology, engineering, mathematics) education, practice is one of the indispensable links. The aim of the design of the STEM teaching aid is to provide a mechanical device which is not limited too much and can provide more feasibility and enable students to build self-mind at will. However, in the prior art, the respective electronic building block set teaching aid has many disadvantages in practical use, for example, the electronic building block modules have complicated parts and various varieties, the modules have poor matching performance of functions and structures and cannot be freely expanded, the electronic building blocks are single in combination form and working mode after being combined, small parts cannot be smoothly built, building and decomposition are difficult, sorting and arrangement are difficult, and the like.

The electronic building block module set product is characterized by that various electronic components and circuits are respectively placed in several plastic building blocks (blocks), and can be spliced together (including electric connection), then the complete building block combination body formed from various shapes, functions and circuits (or programmed combination) can be obtained. Because electronic building blocks module is various, the variety is various, and the user can program fast, assemble various electronic product to can audio-visual understanding splice, the sound of carrying out after the programming, light, electric effect, help the user to learn principles such as electricity, acoustics, optics, mechanical transmission, sensor, automatic control.

In current electronic toy suit module assembly product, power module (battery case) and micro motor drive module are the basic module that electronic toy is used most often, because many-sided restriction, the majority designs respectively for an independent module at present, need communicate each other with the external conductor at the user, just so lead to the external conductor too much, restricted building blocks product assembly scheme's variety. For example, the invention of chinese patent CN202020618437.2 discloses an electronic building block motor device, in which a motor and a control circuit of the motor are built in one module, and then the module is used as a whole for assembling products, and when the electronic building block motor device is used, the motor and the control circuit of the motor must be connected with a power module (a battery box), a control module and other functional modules through external wires, respectively, so that the external wires are multiple, the connection relationship is complex, the connection is easy to make mistakes, and the electronic building block motor device is not suitable for users of low ages (primary schools or kindergartens), and simultaneously the matching performance of assembling with other electronic building block modules is limited. Among current all kinds of building blocks module, including large granule building blocks and small particle building blocks two kinds, be suitable for the user at different age stages respectively, but the shape, the yardstick of current electronic building blocks motor module generally can only be compatible one kind, and can't be compatible these two kinds of building blocks module simultaneously.

The existing electronic building block motor module is only one in a set of combined products, only has a single-drive product combination scheme, and when internal elements (including a motor) and the like of the electronic building block motor module are failed and damaged, or other important modules (control, sensing and battery) and the like are missing or failed, the whole building block combination loses functions and cannot be continuously used, so that teaching can be interrupted and replaced in a whole set to influence the teaching effect for classroom teaching by using the electronic building block as a teaching aid. At present, among the set combined products produced by a plurality of manufacturers, the shapes, structures, functions, circuits and interfaces of the modules are incompatible with each other, and the modules of different models are incompatible with each other and cannot be replaced with each other, so that when a consumer purchases a first set of building block products, partial modules are missing, damaged or failed, the consumer can only integrally discard or purchase a set of building block modules of the same manufacturer and the same model for replacement, resource waste is caused, the burden of a user is increased, and the experience of the user is influenced.

The building block design method in the prior art generally adopts one-by-one design of single modules, does not consider a core module and peripheral modules, has no constraint and cooperative relationship between the core module and the peripheral modules, and has less supportable working modes and functions. The electronic building block module and the building block assembly product designed by the prior art have the defects of excessive building block modules and parts, more external leads, poor comprehensive matching performance of each module, complex connection relation and difficulty in realizing the mutual switching of various combination forms and various working modes. Meanwhile, because the power supply (battery pack), the motor and the control circuit all have certain volume and weight, if the power supply (battery pack), the motor and the control circuit are simply combined (vertically stacked) in a conventional mode, the volume is overlarge, the stability of gravity center stability, structure and operation is difficult to realize, the achievable combination schemes are few, different working modes are difficult to switch, the assembly matching degree of each electronic building block module is greatly influenced, and the flexible selection of the combination schemes and the working modes of the building block products is limited.
