The frame structure of the cube star unit is simple, the cube star unit is not easy to deform, the load plate, parts and the like of the cube star can be conveniently fixed and installed, but the combination of larger structures such as 3u and 6u is not flexible enough, and an improved space is provided.

2.2.2 disadvantages of the prior art solutions

1)3u and 6u are both designed into a whole, and the structure is complex.

2) The circuit connection wiring in the cube star is complicated

3) The circuit board layout is not flexible enough

4) For teaching cube star, the structure is time-consuming and labor-consuming to disassemble and assemble, and teaching experience is influenced

3. Contents of utility model

Aiming at the technical problems in the prior art, the cubic star frame is simple in structure, can be flexibly connected with other cubic star units for assembly, and is assembled to obtain a 2u, 3u, 6u and 12u structure; in addition, aiming at the problem of complex wiring in the original cube star, a connection mode which combines signal transmission and structural connection into a whole is provided; providing a structure for flexibly adjusting the mounting position of a circuit board; meanwhile, the specifications of the screws structurally connected are unified, so that the teaching cube star is more convenient to mount and dismount.

5. Detailed description of the preferred embodiments

The cubic star frame structure is a unit as shown in fig. 6, and can be freely assembled into structures of 2u, 3u, 6u and 12 u. The specific assembly mode is divided into a vertical direction and a horizontal direction, the connection mode in the vertical direction is as shown in fig. 10, and the connection mode in the vertical direction is realized by adopting screws; the panels and the top plate shown in fig. 8 and 9 are connected in the horizontal direction to complete the assembly of the 6u and 12u models. The assembled 3u and 6u structure is shown in fig. 11 and 12.

Fig. 4 shows the shape of the circuit board, fig. 5 shows the shape of the panel of the frame, both of which are identical, and the circuit board and the panel can be replaced to fulfill different functions.

Fig. 1 and fig. 2 are connection diagrams between circuit boards, and the connection is convenient and simple.

Fig. 3 shows the column and the connection mode of the circuit board and the column, a series of holes are designed on the column and are used for connecting the circuit board, so that the position height of the circuit board in the cube star can be selected, and the flexibility is higher.

All the screw apertures are designed consistently, so that the teaching cube satellite is simpler and more convenient to assemble and disassemble, and repeated disassembly and assembly can be realized.

6. The utility model discloses beneficial effect that technical scheme brought

Technically, the novel unit structure is simple, not easy to deform, convenient and flexible to install, strong in operability, and capable of conveniently fixing and installing the load plate and parts of the cube star.

The novel connection mode between the 3u structures is flexible and simple, the structural requirements of the 3u structures can be effectively met by simply assembling a plurality of 1u units, and the structures can be effectively converted between 1u and a plurality of u.

The shape design of the circuit board is consistent with that of the panel, and when the functions need to be added, the panel can be replaced by a circuit board part to complete the function addition.
