Technical Field

The utility model relates to an electronic toy field especially relates to an electronic toy that can realize electrical connection pieces together and takes interface.

Background

There are many brands of building block products in the market, as shown in fig. 1 and fig. 2, the basic splicing mode is as follows: building blocks are spliced together through the convex columns 1 and the grooves 2 on the surfaces of the building blocks, and the building of a model structure is realized.

Many electronic building block products also refer to the splicing and matching mode applying the 'le Gao-like'; the components of the electronic building blocks have their specific functions (sensors, controllers, motors, etc.), but the electrical connections between these components are made using electronic industry standard interfaces, such as: usb, dupont line, various terminal lines.

However, the electronic building block has the following defects:

1. when a user is used for building blocks and creating models, the interfaces of the electronic blocks need to be specially considered, and other blocks need to avoid the positions of the interfaces (avoid blocking the interfaces) and also need to consider the occupied space of an external plug. Often resulting in difficulties for the user to design compact building block models, only to enlarge the dimensions of the building block model as a whole, or to give up certain design ideas.

2. The number of lines is limited (for example, usb is only four lines), the communication protocol is closed, the function can hardly be expanded, and the purpose is single.

3. The line occupies the interface when connecting, therefore when multiple devices are connected together, each device needs to provide multiple groups of interfaces; even if the bus connection mode is adopted, two groups of interfaces are needed on each device.

SUMMERY OF THE UTILITY MODEL

In order to overcome the above disadvantages, an object of the present invention is to provide an electronic building block splicing interface capable of realizing electrical connection, which uses the protruding columns/grooves as electrical interfaces.

In order to achieve the above purpose, the utility model discloses a technical scheme is: an electronic building block splicing interface capable of realizing electrical connection comprises a building block body, wherein a convex column is arranged on the surface of the building block body, and a groove is formed in the lower end face of the building block body; a spring thimble is embedded in the convex column, one end of the spring thimble is exposed on the upper end face of the convex column, and the other end of the spring thimble is exposed in the groove.

Further, the spring thimble is vertically and centrally arranged in the convex column.

Further, each convex column is provided with the spring ejector pin.

Furthermore, one end of a needle tube of the spring thimble is exposed on the upper end surface of the convex column to form a metal contact, and one end of a needle shaft of the spring thimble is exposed in the groove to form a spring needle; when two electronic building blocks are spliced and inserted together, the elastic needle contacts the metal contact, and the electrical connection between the two electronic building blocks is realized.

Compared with the prior art, the utility model has the advantages of it is following:

1. through the application of the spring thimble, the convex column is used as a circuit plug, and the groove is used as an insertion hole of the circuit; when two electronic building blocks are spliced and inserted together, the plug and the jack are arranged in the building blocks, so that extra space is not occupied, and consideration on circuit layout can be reduced.

2. Each convex column is provided with an independent interface which can be used as a universal electrical interface and can be independently provided with specific input/output behaviors; the convex columns can be used independently, and can be combined randomly to realize a specific digital communication protocol (for example: 8080/6800 parallel port, usb/uart/i2c/spi serial port, and the like). Which convex columns are used for what purpose can be flexibly determined according to the model structure of a user.

3. The convex column-groove connection does not occupy the interface. When splicing and inserting, the metal contact of the convex column is contacted with the elastic needle of the groove, but the elastic needle and the metal contact on the respective reverse sides of the convex column and the elastic needle are kept outside, so that continuous splicing and inserting of a plurality of building blocks can be realized, line concentration connection of a plurality of building blocks is formed, only one interface is occupied on each building block, and the number of the building blocks participating in splicing and inserting is not limited.
