[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] See also Figures 1 to 7 As shown, an embodiment of the present application provides a building block assembly, including a main block 1 and a plurality of wheel axles 2. Wheel axle grooves 11 are respectively provided on both sides of the main block 1, and the wheel axle grooves 11 include a plurality of annular grooves 111, each of which has a different diameter and is concentrically arranged. Various wheel axles 2 include an inserting tube portion 21, and the outer diameters of the inserting tube portions 21 of various wheel axles 2 are different. Each wheel axle is selectively inserted into the corresponding annular groove 111 through its inserting tube portion 21. The main block 1 and the wheel axle 2 of the building block assembly of the present application are independent structures, and wheel axles 2 of different sizes can be installed on the main block 1, so that wheels of different sizes can be adapted, which can greatly increase the number of scenes in which the building block assembly can be used, and also greatly improve the design space and interest of assembly. If the wheel axle 2 is broken, only the wheel axle 2 needs to be replaced. A plurality of annular grooves 111 are provided on the main block 1 for different wheel axles 2 . The annular grooves 111 are targeted to ensure that the wheel axles 2 are inserted into the corresponding annular grooves 111 with the best connection stability.

[0039] In some possible implementations, among the annular grooves 111 of the wheel axle groove 11, the groove depth of the annular groove 111 with a small diameter is less than the groove depth of the annular groove 111 with a large diameter. The annular groove 111 with a small diameter corresponds to the wheel axle 2 with a smaller diameter, and is matched with a wheel with a smaller diameter. The width of a wheel with a smaller diameter is also smaller. Therefore, the use of annular grooves 111 with a shallower groove depth can ensure a stable connection. The annular groove 111 with a large diameter corresponds to the wheel axle 2 with a larger diameter, and is matched with a wheel with a larger diameter. The width of a wheel with a larger diameter is also larger. Therefore, the use of annular grooves 111 with a deeper groove depth is required to ensure a stable connection.

[0040] In some possible implementations, the wheel axle groove 11 includes three annular grooves 111, the groove depth of the annular groove 111 with the smallest diameter is 1.5mm-2.5mm, the insertion depth of the annular groove 111 with the largest diameter is 5.5mm-6.5mm, and the groove depth of the annular groove 111 with the middle diameter is 4.5mm-5.5mm. After a large number of use experiments, it is concluded that the above groove depth range is the most stable plug-in range for different wheel axles 2. Preferably, the groove depth of the annular groove 111 with the smallest diameter is 2.0mm, the insertion depth of the annular groove 111 with the largest diameter is 6.0mm, and the groove depth of the annular groove 111 with the middle diameter is 5.0mm.

[0041] In some possible implementations, the annular groove 111 has a tapered notch section 1111, and the width of the tapered notch section 1111 gradually increases in the direction from the bottom wall of the annular groove 111 to the outside of the main block 1. When the wheel axle 2 is installed in the annular groove 111, the tapered notch section 1111 has a guiding function, which saves time and effort when aligning the wheel axle 2 with the annular groove 111.

[0042] In some possible implementations, a cylindrical body 12 is formed between adjacent annular grooves 111, and the thickness of the cylinder wall at one end of the cylindrical body 12 gradually decreases in the direction from the bottom wall of the annular groove 111 to the outside of the main block 1. The tapered notch section 1111 is formed by gradually decreasing the thickness of the end of the cylindrical body 12, and the transition of the end of the cylindrical body 12 is relatively smooth, so that it is not easy to get stuck or damaged when the wheel axle 2 is plugged in.

[0043] In some possible implementation schemes, the inner wall of the annular groove 111 is provided with a convex rib 13, and the inserting tube portion 21 is provided with a strip groove 211. When the wheel axle 2 is inserted into the annular groove 111, the convex rib 13 is embedded in the strip groove 211. The convex rib 13 cooperates with the strip groove 211 to play the role of installation guidance and rotation limit. When the wheel axle 2 is installed in the annular groove 111, the convex rib 13 guides, making the installation smoother and smoother. During the rotation of the wheel, the convex rib 13 and the strip groove 211 limit to ensure that the wheel axle 2 and the main block 1 do not rotate relative to each other, which can improve the connection stability between the wheel axle 2 and the main block 1. In addition, the convex rib 13 also plays the role of a reinforcing rib, which improves the overall strength of the cylinder 12 and prolongs its service life.

[0044] In some possible implementations, each of the annular grooves 111 may be formed by being recessed on the surface of the main block 1. This arrangement has high structural strength. Alternatively, a plurality of cylindrical bodies 12 are protruding from the surface of the main block 1. The outer diameters of the cylindrical bodies 12 are different. The cylindrical bodies 12 are concentrically arranged. The annular groove 111 is formed between two adjacent cylindrical bodies 12. This arrangement is convenient for production and the wheel axle 2 is easy to install. The two structures can be selected according to the size, shape, usage scenario, etc. of the building blocks.

[0045] In some possible implementations, the inserting tube portion 21 of some of the wheel axles 2 has at least two inserting rings 212, each inserting ring 212 has a different outer diameter, and each inserting ring 212 is concentrically arranged. When the wheel axle 2 is inserted into the wheel axle groove 11, each inserting ring 212 is respectively inserted into the corresponding annular groove 111. The wheel axle 2 can be a hollow tube with only one inserting ring 212, which is directly inserted into the matching annular groove 111. The wheel axle 2 can also be provided with an end face at the plug-in end, and at least two inserting rings 212 are provided on the end face. Different inserting rings 212 are inserted into different annular grooves 111, thereby improving the connection stability between the wheel axle 2 and the main block 1. A wheel with a larger diameter requires a greater connection force. Preferably, a wheel axle 2 with a smaller diameter includes one inserting ring 212, and a wheel axle 2 with a larger diameter includes at least two inserting rings 212.

[0046] In some possible implementations, the main block 1 is provided with a plurality of bosses 14. Insertion spaces are formed between the bosses 14, and slots matching the bosses 14 are provided on other building block particles, and the slots can be inserted into the bosses 14 on the main block 1, so that various shapes can be assembled, making the building blocks more playable.

[0047] In some possible implementations, an extension plate 15 is provided at one end of the main block 1, and a plurality of bosses 14 are provided on the extension plate 15. The main block 1 is mainly a partial structure of the chassis of a vehicle, etc., on which two wheels can be connected, and the extension plate 15 can be plugged with the extension plate 15 on another main block 1 to form a complete chassis and achieve a walking effect.
