Description

Technical Field

[0001] The present application relates to the technical field of educational toys, and in particular to a building block car. Background Art

[0002] Building blocks were originally simple toys used to inspire the intelligence of infants and young children. Usually, the edges of the building blocks are 90 degrees, but the finished products are not limited to squares. By connecting enough 90-degree building blocks tightly together, you can build objects with both spherical and curved shapes. As long as you have enough building blocks, you can build almost anything.

[0003] Therefore, with the continuous development, the group of people who like building blocks is no longer limited to infants and young children, and the assembly of building blocks has gradually become more complicated, such as car models, airplane models, etc. The difficulty of assembling these models is obviously too high for infants and young children, and the finished products after assembly are fixed in shape, lacking linkage with other building blocks, and low playability, which limits the creativity of infants and young children and is not conducive to the development of intelligence. Utility Model Content

[0004] The embodiment of the present application provides a building block car to at least solve the technical problems in the related art such as the building block car being difficult to assemble, having a fixed assembly shape, lacking linkage with other building blocks, and having low playability.

[0006] In some embodiments, a second connecting portion is provided at the lower portion of the vehicle body, and the rotating shaft is rotatably snap-fitted or plugged into the second connecting portion.

[0007] In some embodiments, connecting ends connected to the wheels are respectively provided at both ends of the rotating shaft, a connecting piece is detachably provided in the wheel, and the connecting end is rotatably provided in the connecting piece.

[0008] In some of the embodiments, a clamping portion is provided on the connecting end, a connecting hole matching with the clamping portion is provided on the connecting piece, and an avoidance groove extending along the depth direction of the connecting hole is distributed on the inner wall of the connecting hole. The avoidance groove can facilitate the deformation of the connecting hole so that the clamping portion can enter the connecting hole.

[0009] In some embodiments, a positioning portion parallel to the rotating shaft is provided on the outer edge of the connecting member, and positioning grooves cooperating with the positioning portion are distributed circumferentially on the inner wall of the wheel, so that the connecting member and the wheel are relatively fixed in the circumferential direction.

[0010] In some embodiments, the connecting member is provided with an abutment portion extending radially outward, and the abutment portion abuts against the inner wall of the wheel, so that the connecting member and the wheel are firmly matched.

[0011] In some embodiments, the plug posts are arranged in at least two rows and are equidistantly extended along the length direction of the vehicle body.

[0012] In some embodiments, the plug-in column is hollow inside and has an opening at the top.

In this embodiment, the plug posts 1.2 are arranged in two rows and are equidistantly arranged in six rows in the direction extending toward the vehicle body 1, with a total of 12.

[0031] Specifically, the plug-in column 1.2 is hollow inside and has an opening at the top. The plug-in column 1.2 can also be solid.

[0032] Furthermore, two groups of anti-skid grooves 2.3 are spaced apart from each other along the circumferential direction on the surface of the wheel 2.

[0033] Furthermore, the vehicle body 1 is provided with an escape portion 1 . 3 for accommodating the wheel 2 .

[0034] Working method and principle: After the building block car is assembled, it can be used for children to push and play.
