Problems solved by technology

[0005] In the existing electronic building block set module combination products, the power module (battery box) and the micro motor drive module are the most commonly used basic modules of electronic building blocks. Due to various restrictions, most of them are designed as an independent module respectively. Users need to use external wires to communicate with each other, which leads to too many external wires and limits the diversity of building block product assembly solutions

For example, the Chinese invention patent CN202020618437.2 discloses an electronic building block motor device, which builds the motor and the control circuit of the motor into a module, and then assembles the product as a whole. When using it, it must be connected to the power supply through external wires. Modules (battery boxes), control modules and other functional modules are connected, resulting in many external wires, complicated connection relationships, and error-prone connections. Compatibility of the assembly

Among the various types of existing building block modules, there are two kinds of large particle building blocks and small particle building blocks, which are suitable for users of different ages. However, the shape and size of the existing electronic building block motor modules are generally only compatible with one type. It cannot be compatible with these two types of building block modules at the same time

[0006] For the existing electronic building block motor modules, there is often only one product in a set combination product, and there is only a single-drive product combination solution, and when its internal components (including motors) fail or are damaged, or other important modules (control, sensor) , battery) etc. are missing or faulty, the entire building block combination loses its function and cannot be used any longer. For classroom teaching using electronic building blocks as teaching aids, the teaching can only be interrupted and the whole set replaced, which will affect the teaching effect.

At present, the shape, structure, function, circuit, and interface of each module are incompatible among the packaged combination products produced by many manufacturers, and the modules of different models are also incompatible and cannot replace each other. When some modules of a set of building block products are missing, damaged or faulty, they can only be discarded as a whole or purchased another set of building block modules of the same manufacturer and model for replacement, resulting in waste of resources, increasing the burden on users, and affecting the quality of life of users. to experience

[0007] The building block design method in the prior art usually adopts the design of a single module one by one, without considering the core module and peripheral modules, there is no constraint and synergistic relationship between them, and there are few supported working modes and functions

The electronic building block modules and building block combination products designed by the above-mentioned prior art have too many building block modules and parts, many external wires, poor comprehensive matching of each module, complicated connection relationship, and it is difficult to realize various combinations and various tasks. Switch between modes

At the same time, since the power supply (battery pack), motor and control circuit all have a certain volume and weight, if they are simply combined (stacked up and down) according to the conventional method, the volume will be too large, and it is difficult to achieve a stable center of gravity and a stable structure. And the stability of operation, resulting in less realizable combination schemes and difficulty in switching between different working modes, which greatly affects the assembly matching degree of each electronic building block module, thus limiting the combination scheme of building block products and the flexible selection of working modes
