Description

Technical Field

[0001] The utility model relates to the technical field of toys, in particular to a track building block and a track car toy. Background Art

[0002] Track toys are widely popular among children and can be broadly categorized as fixed track toys and interlocking track toys. Interlocking track toys are particularly popular because they not only develop children's practical skills but also foster active thinking and maximize their imagination and creativity. Track car toys with magnetic tracks are particularly popular because they can be assembled into various three-dimensional structures. By arranging the magnetic tracks in different directions, the track car can travel above, below, or to the side of the track blocks.

[0003] There are two main types of tracks for existing track car toys. One is a plurality of sheet track pieces spliced ​​together. This type of track needs a lot of brackets to be matched with the three-dimensional track. If there are not enough brackets, it is easy to collapse. The splicing is very troublesome and cannot be moved after splicing.

[0004] Another approach involves joining multiple thicker building blocks together, with magnetic tracks and connecting structures on several surfaces. However, existing thicker building blocks connect adjacent track blocks magnetically. This magnetic connection is prone to inaccurate and unstable magnetic positioning, resulting in unstable joints and a track that easily falls apart. Furthermore, the three-dimensional track requires numerous supports, and even after assembly, it can be difficult to move.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0038] By adopting the above technical solution, this application has the following beneficial effects:

[0039] First, when playing with the track car toy provided by the present application, it is necessary to plug the first coupling seat of one track building block into the second coupling seat of another track building block. During plugging, the adjacent building blocks are squeezed toward each other along the thickness extension direction of the protrusions, and the smooth protrusions on the second coupling seat will slide into the slots on the first coupling seat and engage with the edges of the slots for stability.

DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0051] In the description of the present invention, it should be noted that the terms "upper", "lower", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0052] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0053] Example 1: Figures 2 to 7 As shown, an embodiment of the present application provides a track building block, comprising a building block shell 1, a first magnetic strip 2, a first binding seat 3, and a second binding seat 4. The first magnetic strip 2 is arranged on the building block shell 1, and the first magnetic strip 2 extends along the extension direction of the building block shell 1. The first binding seat 3 is arranged on the building block shell 1, and the first binding seat 3 is located at one end of the first magnetic strip 2. The first binding seat 3 has a protrusion 31, and a slot 32 is provided on the lateral end face of the protrusion 31. The second binding seat 4 is arranged on the building block shell 1, and the second binding seat 4 is located at the other end of the first magnetic strip 2. The second binding seat 4 has a groove 41, and a hollow opening 42 and an elastic sheet 43 are provided on the inner wall of the groove 41. The elastic sheet 43 extends to the hollow opening 42, and a smooth protrusion 44 is provided on one side of the elastic sheet 43 along the thickness direction. Multiple track building blocks are detachably connected. When two track building blocks are connected, the protrusion 31 of the first coupling seat 3 of one is inserted into the groove 41 of the second coupling seat 4 of the other, and the smooth protrusion 44 of the elastic piece 43 in the groove 41 is snapped into the slot 32 of the protrusion 31; under the action of external force along the length direction of the track building blocks, the smooth protrusion 44 slides away from the slot 32, and the two track building blocks are separated.

[0054] When playing with the track car toy provided by the present application, the first coupling seat 3 of one track building block needs to be plugged into the second coupling seat 4 of another track building block. During the plugging, the adjacent building blocks are squeezed toward each other along the thickness extension direction of the protrusion 31, and the smooth protrusion 44 on the second coupling seat 4 will slide into the slot 32 on the first coupling seat 3 and be stably engaged with the edge of the slot 32. The two adjacent building blocks are connected by inserting and engaging, and the two adjacent building blocks can be connected firmly. When splicing into a three-dimensional track, no brackets or very few brackets can be used to ensure the stability of the track. Moreover, the track has a strong integrity after being spliced ​​and formed, and it is not easy to fall apart even if it is taken or moved at will.

[0055] To separate two adjacent building blocks, the blocks are pulled in opposite directions along the thickness of the protrusion 31. Since both sides of the smooth protrusion 44 are smooth, applying a force along the thickness of the protrusion 31 facilitates assembly and disassembly. The hollow opening 42 and elastic sheet 43 increase the elasticity of the smooth protrusion 44, making assembly and disassembly of adjacent building blocks smoother.

[0056] Among them, the first combination seat 3 and the second combination seat 4 are respectively arranged at the two ends of the first magnetic strip 2, which can ensure that after the first combination seat 3 of one track building block is plugged into the second combination seat 4 of another track building block, the first magnetic strips 2 of the two adjacent track building blocks are spliced ​​into a continuous track.

[0057] Preferably, the cross section of the smooth protrusion 44 is semicircular.

[0058] In some possible embodiments, the slot 32 extends along the protruding direction of the protrusion 31. The smooth protrusion 44 is provided on one side of the elastic sheet 43 along the thickness direction. The smooth protrusion 44 is a ridge extending along the width direction of the elastic sheet 43. When two adjacent building blocks are plugged together, the slot 32 abuts against the smooth protrusion 44, causing the elastic sheet 43 to deform. When the smooth protrusion 44 slides into the recessed groove at the bottom of the slot 32, the smooth protrusion 44 sinks, and the elastic sheet 43 recovers its deformation, ensuring a secure connection between the two adjacent building blocks. To disassemble the adjacent building blocks, the blocks are pulled away from each other, causing the elastic sheet 43 to deform, and the smooth protrusion 44 to disengage from the recessed groove and enter the slide groove, where it slides out, separating the two adjacent building blocks.

[0059] The smooth protrusion 44 extends along the width direction of the elastic piece 43, so that the smooth protrusion 44 is long enough to ensure stability during the clamping process. When disassembling two adjacent building blocks, the force will be more uniform, which can reduce the occurrence of jamming.

[0060] In some possible embodiments, the peripheral sidewall 11 of the slot 32 includes an end wall 34 and side walls 35 located on either side of the end wall 34. The side walls 35 extend along the protruding direction of the protrusion 31. The end wall 34 is located on the side of the side wall 35 facing away from the building block housing 1 and has an inclined wall surface. Under the action of an external force, the smooth protrusion 44 of one of the two track building blocks can slide away from the slot 32 along the end wall 34 of the other. The side walls 35 on both sides can limit the ends of the smooth protrusion 44, ensuring that the smooth protrusion 44 slides along the slide groove and ultimately smoothly enters the slot for engagement when installing or disassembling adjacent building blocks. The angle between the end wall 34 and the bottom wall of the slot 32 is an obtuse angle. Preferably, the angle between the end wall 34 and the bottom wall of the slot 32 is between 125° and 145°. In this way, when the smooth protrusion 44 is released from the sliding groove, it will be very smooth without any jamming.

[0061] In some possible embodiments, the first coupling seat 3 has a boss 36, which is connected to the building block shell 1. The boss 36 has a flange 37 surrounding the boss 36. The building block shell 1 is provided with an annular groove corresponding to the flange 37. The building block shell 1 includes at least two parts. When the first coupling seat 3 is connected to the building block shell 1, the flange 37 is inserted into the annular groove and buckles the parts of the building block.

[0062] The protrusion 31 is arranged on the boss 36, and the boss 36 is provided with a first deformation opening 33 at a position corresponding to the slot 32. The first deformation opening 33 is connected to the slot 32, and the embedding groove is located in the deformation opening. The bottom wall of the groove 41 of the second coupling seat 4 is provided with a second deformation opening 45, and the second deformation opening 45 is connected to the hollow opening 42. The first deformation opening 33 and the second deformation opening 45 can both enhance the deformation capacity of the setting position. When the first coupling seat 3 and the second coupling seat 4 are plugged in or disassembled, the structures at the first deformation opening 33 and the second deformation opening 45 will be deformed by the squeezing of the smooth protrusion 44. The provision of the first deformation opening 33 and the second deformation opening 45 can enhance the deformation capacity of the outer wall of the protrusion 31 and the inner wall of the groove 41, thereby reducing the possibility of the outer wall of the protrusion 31 and the inner wall of the groove 41 being subjected to stress cracking.

[0063] In some possible embodiments, the first and second coupling seats 3 and 4 are respectively provided at both ends of the building block along the length direction, and the first and / or second coupling seats 3 and / or 4 are also provided at the portion between the two ends of the building block shell 1. In this way, a building block shell 1 is provided with multiple first coupling seats 3 and / or multiple second coupling seats 4, which allows track building blocks to be connected not only sequentially but also cross-connected, increasing the number of possible splicing combinations between track building blocks and making the track building blocks more interesting.

[0064] In some possible embodiments, the building block shell 1 has four side walls 11 and two end walls 12. The four side walls 11 are arranged in sequence around the circumference of the building block shell 1, and two adjacent side walls 11 are vertically connected. The two end walls 12 are respectively located at the two ends of the side wall 11, and the first binding seat 3 and the second binding seat 4 are respectively provided on the two end walls 12. The first binding seat 3 and / or the second binding seat 4 can be provided on the side wall 11. The first binding seat 3 and the second binding seat 4 respectively provided on the two end walls 12 can ensure that the two track building blocks can be connected. The first binding seat 3 and / or the second binding seat 4 can be provided on the side wall 11, or they may not be provided. For example, it may be inconvenient to provide a binding seat on the side wall 11 for corner building blocks or special-shaped building blocks. Whether to provide the first binding seat 3 and / or the second binding seat 4 can be selected according to the shape and function of the building blocks.

[0065] In some possible implementations, the track building block includes a second magnetic strip 5. The second magnetic strip 5 is disposed on the building block shell 1, perpendicular to the first magnetic strip 2. The building block shell 1 is provided with a first coupling seat 3 and a second coupling seat 4 at either end of the second magnetic strip 5. This not only allows for more possibilities in building block splicing but also in track configuration. After splicing, multiple magnetic track vehicles can be used on different tracks, creating more ways to play and further enhancing the fun of the track building block.

[0066] In some possible embodiments, the second magnetic strip 5 includes side strips located on both sides of the first magnetic strip 2 along the width direction, and the side strips are fixedly connected to the first magnetic strip 2. This arrangement prevents the two magnetic strips from overlapping to form a bulge, and makes the intersection of the first magnetic strip 2 and the second magnetic strip 5 smooth, so that the magnetic rail vehicle will not get stuck or fall when passing through.

[0067] In some possible embodiments, the first magnetic strip 2 and the second magnetic strip 5 are integrally formed. This eliminates the need for a joint seam, and the intersection of the first magnetic strip 2 and the second magnetic strip 5 is smoother, further enhancing the smoothness of the magnetic railcar passing through the intersection.

[0068] Example 2: Figure 1 As shown, an embodiment of the present application provides a track car toy, comprising a plurality of track building blocks 100 as described in Example 1 and a toy car. The track building blocks 100 are spliced ​​together to form different shapes, and the first magnetic strips 2 on the spliced ​​track building blocks 100 are connected. The toy car has rollers and a magnetic body. The magnetic body and the first magnetic strip 2 are magnetically attracted to each other, and the rollers are rotatably supported on the first magnetic strip 2.

[0069] The track of the track car toy provided in this embodiment is formed by splicing the track building blocks 100 in the first embodiment. When splicing the track, the first coupling seat 3 of one track building block 100 is plugged into the second coupling seat 4 of another track building block 100. When plugging in, the adjacent building blocks are squeezed toward each other along the thickness extension direction of the protrusion 31, and the smooth protrusion 44 on the second coupling seat 4 will slide into the slot 32 on the first coupling seat 3 and be stably engaged with the edge of the slot 32. The two adjacent building blocks are connected by inserting and engaging, and the two adjacent building blocks can be connected firmly. When splicing into a three-dimensional track, no brackets or very few brackets can be used to ensure the stability of the track. Moreover, the track has a strong integrity after being spliced ​​and formed, and it is not easy to fall apart even if it is taken or moved at will.

[0070] To separate two adjacent building blocks, the blocks are pulled in opposite directions along the thickness of the protrusion 31. Since both sides of the smooth protrusion 44 are smooth, applying a force along the thickness of the protrusion 31 facilitates assembly and disassembly. The hollow opening 42 and elastic sheet 43 increase the elasticity of the smooth protrusion 44, making assembly and disassembly of adjacent building blocks smoother.

[0071] Thereby, the track car toy is more interesting when played.
