[0034] Example 1:

[0035] Please refer to Figure 1-7 , this embodiment provides a rack and pinion building block mechanism with a track, comprising a rack building block 10 and a gear building block assembly meshing with each other;

[0036] A meshing portion 11 is formed on one side of the rack building block 10. The meshing portion 11 has a plurality of first meshing teeth in a linear array. The meshing portion 11 is arranged along the length direction of the rack building block 10. A first slide groove 12 is formed on one side adjacent to the meshing portion 11. The first slide groove 12 is arranged along the length direction of the rack building block 10.

[0037] The gear building block assembly includes a first mating block 20 and a first gear building block 30. The first mating block 20 has a first mating portion 21 and a first supporting portion 22. The first mating portion 21 is slidably connected to the first chute 12, thereby allowing the gear building block assembly to translate longitudinally relative to the rack building block 10. The first mating portion 21 has a sliding baffle at its end, which contacts the bottom wall and side surface of the first chute 12 to improve relative sliding stability.

[0038] The first support portion 22 is rotatably connected to the first gear building block 30 ; the first gear building block 30 has a plurality of second meshing teeth in a circumferential annular array, and the second meshing teeth mesh with the first meshing teeth for transmission.

[0039] The rack and pinion building block mechanism with tracks of this embodiment is modified on the original rack structure, and the first gear building block 30 is connected to the rack building block 10 through the first matching building block 20, and the first matching portion 21 is inserted into the end of the first slide groove 12 to realize the sliding fit between the first matching building block 20 and the rack building block 10, and the gear building block assembly is constrained in the length direction of the rack building block 10, and the function of the slide groove is added, so that when connected and used, the relative movement between the building block mechanisms is smoother and the connection is more secure; the first supporting portion 22 provides support for the first gear building block 30, improves the load-bearing capacity of the gear building block assembly, provides a foundation for the external structure, and effectively avoids the problems of tooth jumping due to overload or offset in the existing building blocks during operation, thereby achieving a functional upgrade.

[0040] Furthermore, the rack block 10 is formed with a second chute 13, which is arranged along the length of the rack block 10. The second chute 13 and the first chute 12 are symmetrically arranged on either side of the meshing portion 11. The gear block assembly also includes a second mating block 40, which is arranged on either side of the meshing portion 11 opposite the first mating block 20. The second mating block 40 has a second mating portion 41 and a second supporting portion 42, the second mating portion 41 being slidably connected to the second chute 13; the second supporting portion 42 is rotatably connected to the first gear block 30. By mating the first mating block 20 and the second mating portion 41 with the first chute 12 and the second chute 13, respectively, the rack block 10 is clamped to the gear block assembly, further improving the stability and load-bearing capacity of the building block mechanism.

[0041] The gear building block assembly in this embodiment also includes a second gear building block 50 having a plurality of second meshing teeth arranged in a circumferential annular array. The second gear building block 50 is rotatably connected to the first mating building block 20 and the second mating building block 40 on either side. The first gear building block 30 and the second gear building block 50 can be positioned at either end of the gear building block assembly to improve stability. In other embodiments, more than two gear building blocks can be positioned between the first mating building block 20 and the second mating building block 40. Persons skilled in the art can configure the gear building blocks based on the load-bearing requirements of the overall structure.

[0042] In this embodiment, the first support portion 22 is formed with a plurality of first circular connection holes 221, and the second support portion 42 is formed with a plurality of second circular connection holes 421. The first and second circular connection holes 221 and 421 are symmetrically arranged. These holes primarily serve to provide a connection base for the installation of gear blocks and link components. The number of these holes is seven, allowing users to select the appropriate location for the gear blocks, adapting to a variety of environments.

[0043] The first gear building block 30 is connected to the first matching building block 20 and the second matching building block 40 through the cross-axis building block 60. Specifically, a cross-connecting hole 31 is provided on the axis of the first gear building block 30; the gear building block assembly also includes a cross-axis building block 60; the cross-axis building block 60 is inserted into the cross-connecting hole 31, and the two ends of the cross-axis building block 60 extend from the opposite sides of the first gear building block 30 respectively; the two ends of the cross-axis building block 60 are respectively inserted into the first circular connecting hole 221 and the second circular connecting hole 421. Similarly, the second gear building block 50 is connected to the first matching building block 20 and the second matching building block 40 in the same way, which will not be repeated here. By having a cross-connecting hole 31 at both ends of the gear building block, the cross-axis building block 60 can be installed for easy reinforcement.

[0044] The gear building block assembly of this embodiment also includes a linking block 70, which is positioned between the first mating block 20 and the second mating block 40. The linking block 70 is provided with a first friction pin 71 and a second friction pin 72. The first friction pin 71 is inserted into the first circular connecting hole 221, and the second friction pin 72 is inserted into the second circular connecting hole 421. The first mating block 20 and the second mating block 40 are generally configured to be used together. During use, the linking block 70 is used to mate with the rack block 10, enabling stable sliding. Several expansion holes 73 are formed on the linking block 70, providing a foundation for structural expansion, facilitating integration with other building block structures and enhancing the playability of the building blocks.

[0045] Furthermore, the rack building block 10 is formed with a beam portion 14, located on the side opposite the meshing portion 11. Thirteen expansion holes 73 are provided on the beam portion 14, with adjacent expansion holes 73 staggered 90 degrees. Several double-ended friction pin blocks 80 are connected to the expansion holes 73. The staggered, intersecting beams facilitate expansion and construction. Cross-shaped connecting holes 31 are formed at both ends of the beam portion 14 for mounting cross-shaped accessories, facilitating reinforcement.

[0046] Based on the above structure, the rack and pinion building block structure with tracks in this embodiment can provide a variety of building block play methods:

[0047] Play method 1: Fix the rack building block 10 in the fixed building block structure, and then build the gear building block assembly as needed. You can add additional building block components to the gear building block assembly to achieve sliding, forward movement, etc.

[0048] Play method 2: You can fix the gear building block assembly in the fixed building block structure, and then turn the gear to move the rack building block 10.

[0049] The rack and pinion building block structure with tracks in this embodiment provides a new building block assembly solution, enabling the use of rack and pinion mechanisms in building blocks to more smoothly convert rotational motion into linear motion, increase load capacity, and expand upon the existing structure, achieving a functional upgrade. This assembly solution, which better meets practical needs, helps children understand basic mechanical principles such as gear ratios, power transmission, and motion conversion, enhancing the toy's educational value and fun.

[0050] Although certain components and embodiments of the present application have been illustrated and described, many modifications and changes (e.g., changes in size, dimensions, structure, shape and proportions of the various elements, mounting arrangements, use of materials, colors, orientations, etc.) may occur to those skilled in the art without actually departing from the scope and spirit of the claims.

[0051] Finally, it should be noted that the above-mentioned implementation mode is only a preferred embodiment mode of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
