Figure 1 As shown in the figure, the through holes 110 and the bosses 120 are arranged on the bottom plate 100 in a row-column manner.

[0028] The fixing device 200 comprises a suction accessory 210 and a fixing piece 220. The suction accessory 210 has a first contact surface 211 which can be connected to one side of the bottom plate 100, the fixing piece 220 has a second contact surface 221 which can be connected to the other side of the bottom plate 100, and the first contact surface 211 and the second contact surface 221 can cover the through holes 110. Meanwhile, the suction accessory 210 and the fixing piece 220 are provided with a connecting structure corresponding to the through holes 110, the connecting structure comprises a first connecting part and a second connecting part which are separately arranged on the suction accessory 210 and the fixing piece 220, and the first connecting part and the second connecting part are detachably fixedly connected. It can be understood that the first connecting part and the second connecting part are detachably fixedly connected in one or more connecting modes such as threaded connection, buckle connection, inner and outer thread connection, magic tape connection, magnetic attraction connection, plug-in connection and adhesive connection. Therefore, through the above arrangement, the suction accessory 210 and the fixing piece 220 can be detachably connected to any through hole 110, so that the player can adjust the number and position of the fixing device 200 on the bottom plate 100 as needed, so as to facilitate use.

[0029] It can be understood that the suction accessory 210 further has a suction part 212 which can be adsorbed and fixed to an external contact surface. In the embodiment, the suction part 212 is composed of a magnet embedded in the suction accessory 210, and the bottom plate 100 can be adsorbed and fixed to an iron material, for example, a refrigerator door, an iron blackboard and the like, through the magnet. In other embodiments of the utility model, the suction part 212 can be composed of a suction disc fixed to the suction accessory 210, and the bottom plate 100 can be adsorbed and fixed to a contact surface with a flat surface, for example, a glass plane, a ceramic tile surface and the like, through the suction disc.

[0030] In the embodiment, the first connecting part is a connecting groove 213 arranged on the suction accessory 210, the connecting groove 213 is arranged inwardly recessed along the first contact surface 211, and the inner wall of the connecting groove 213 is provided with a buckle step 2131, which is used for detachably fixing the second connecting part in the connecting groove 213. Correspondingly, the second connecting part is a buckle column 222 arranged on the fixing part 220, the buckle column 222 is arranged outwardly protruded along the second contact surface 221, the buckle column 222 can be elastically opened and closed, and can be inserted into the connecting groove 213 and buckled on the buckle step 2131. Through the above arrangement, when it is needed to fix the fixing device 200 on the bottom plate 100, the first contact surface 211 and the second contact surface 221 are placed relative to the two side surfaces of the bottom plate 100, and then the suction accessory 210 and the fixing part 220 are moved towards any through hole 110, so that the buckle column 222 can pass through the through hole 110 and enter the connecting groove 213, until the buckle column 222 is buckled on the buckle step 2131, thereby fixing the fixing device 200 on the bottom plate 100. When it is needed to disassemble the fixing device 200 from the bottom plate 100, the suction accessory 210 and the fixing part 220 are relatively separated, so that the buckle column 222 is elastically deformed to be separated from the buckle step 2131, then the buckle column 222 can be pulled out from the connecting groove 213, thereby the fixing device 200 can be disassembled from the bottom plate 100. In other embodiments of the utility model, the first connecting part can be arranged as a structure corresponding to other connecting modes, such as a threaded hole, a plug-in column or a plug-in groove, a magic tape, a gluing surface, a magnetic suction surface, etc., and correspondingly, the second connecting part is arranged as a structure which can be detachably connected with the first connecting part.

[0031] In the embodiment, the connecting groove 213 extends through the other side away from the first contact surface 211, and a positioning step 2132 is arranged in the connecting groove 213, and the adsorption part 212 is clamped and fixed on the positioning step 2132, so that the adsorption part 212 can be firmly connected in the adsorption accessory 210. It can be understood that the main body of the adsorption accessory 210 includes an integrally formed center block 214 and an extension block 215, the center block 214 is provided with the connecting groove 213 and the first fixing groove 217, and the side of the center block 214 away from the first contact surface 211 is covered with a non-slip pad 218, which is used to contact the external contact surface when the adsorption accessory 210 is adsorbed and fixed on the external contact surface, and plays a role in preventing the adsorption accessory 210 from sliding. The side of the center block 214 extends outwardly and is provided with at least two extension blocks 215, and in the embodiment, the number of the extension blocks 215 is four and is distributed in a cross shape, and each extension block 215 is also provided with the first fixing groove 217, which is used to be detachably fixed on the external building block (such as a Lego basic building block) by a latch (such as a mushroom-shaped latch), so that the bottom plate 100 can also be detachably connected to the external building block through the first fixing groove 217 and the latch. It can be understood that, in the embodiment, the center block 214 and the extension block 215 are both provided with the first fixing groove 217, so that the adsorption accessory 210 can be detachably fixed on the external building block through the latch, and thus the external building block can be adsorbed and fixed on the external contact surface through the adsorption accessory 210. That is, the adsorption accessory 210 can also be used to adsorb and fix the external building block on the external contact surface, so that the applicability and practicability of the fixing device 200 are higher. In other embodiments of the utility model, the connecting groove 213 can not be provided in a through structure, and other structures for fixing and connecting the adsorption part 212 are arranged on the adsorption accessory 210, such as other groove structures or clamping column structures. The main body of the adsorption accessory 210 can only include the center block 214, or the main body can have other appearance structures, the main body of the adsorption accessory 210 can not be provided with the first fixing groove 217, or the center block 214 can not be provided with the first fixing groove 217 and / or the non-slip pad 218.

[0032] It can be understood that the body of the fixing part 220 is flat, and the thickness of the body is less than the height of the boss 120 on the bottom plate 100, so that when the fixing part 220 is connected to the bottom plate 100, the fixing part 220 can not affect the fixation of the electronic building block assembly. One side of the body is a second contact surface 221, and in the embodiment, the fixing part 220 is provided with a positioning ring 224 outwardly protruding along the second contact surface 221, which can be adaptively connected in the through hole 110 to prevent the fixing device 200 from moving in the through hole 110, thereby avoiding the case that the fixing device 200 shakes on the bottom plate 100 and affects the use effect. In other embodiments of the utility model, the body of the fixing part 220 can not be provided with the positioning ring 224.

[0033] For clarity, certain features of the present application that are, for brevity, described in relation to only one or a few embodiments, can be combined with features of other embodiments.
