Track toys

Abstract

A track toy includes a track body and a toy body. The track body comprises multiple basic track units, each with a guide rail arranged in a front-to-back direction. The toy body has a power mechanism capable of moving along the guide rails. The track body further includes at least one intersecting track unit, each with two guide rails arranged in a cross shape, forming an intersecting guide rail segment at the intersection. This intersecting guide rail segment consists of four guide rail protrusions arranged in a rectangular array. This track toy can be freely assembled into tracks of various shapes as needed, and only a single intersecting track unit is required to assemble a track with an intersecting guide rail segment, offering greater versatility in assembly.

Claims

1. A track toy, comprising a track body and a toy body, the track body comprising multiple basic track units, each basic track unit being provided with a guide rail arranged in a front-back direction; the toy body being provided with a power mechanism capable of moving along the guide rail; characterized in that: the track body further comprises at least one intersecting track unit, the intersecting track unit being provided with two of the guide rails, the two guide rails being intersected to form a cross shape and forming an intersecting guide rail segment at the intersection, the intersecting guide rail segment being composed of four guide rail protrusions arranged in a rectangular array.

2. The track toy as claimed in claim 1, wherein, Each of the basic track units has a guide groove arranged in the front-to-back direction. The guide rail is located in the middle of the bottom wall of the guide groove. The two side walls of the guide groove have slots extending in the length direction. The lower surface of the toy body has two downwardly extending block structures. The lower end of the block structure has an outwardly protruding part that matches the slot.

3. The track toy as claimed in claim 2, wherein, The cross track unit is provided with two guide grooves and two guide rails, with each guide groove and guide rail corresponding to the other. The two guide grooves are arranged in a cross shape and form a cross area at the intersection. The two guide rails are arranged along the length direction of the corresponding guide grooves, and the two guide rails form the cross guide rail segment in the cross area.

4. The track toy as claimed in claim 3, wherein, The four perimeters of the intersection area are respectively provided with guide block groups, each guide block group includes at least two guide blocks, each guide block includes a vertical section and a horizontal section. The vertical section is set on the bottom wall of the guide groove in the up-down direction and is located on the side of the corresponding guide rail. One end of the horizontal section is connected to the upper end of the vertical section, and the other end of the horizontal section faces the intersection guide rail section and is flush with the groove wall of the guide groove. There is a gap between each guide block and the groove wall of the adjacent guide groove, and the size of the gap is greater than the thickness of the locking block structure.

5. The track toy as claimed in claim 2, wherein, The guide rail is a rack; the power mechanism includes a power source, a motor and a gear set. The power source is electrically connected to the motor. The output shaft of the motor is connected to the first gear of the gear set. A portion of the last gear of the gear set extends out of the toy body and meshes with the guide rail. The portion of the last gear of the gear set that protrudes from the toy body is located between the two locking structures.

6. The track toy as claimed in claim 5, wherein, The spacing between two adjacent guide rail protrusions is the same as the tooth pitch of the last stage gear of the gear set.

7. The track toy as claimed in claim 2, wherein, The upper side of the protrusion slopes outward from top to bottom, and the lower side of the protrusion slopes outward from bottom to top. The upper and lower edges of the sidewall of the guide groove are both arc-shaped.

8. The track toy as claimed in claim 2, wherein, The toy body has a through hole, the locking block structure is hinged to the toy body, and the lower end of the locking block structure protrudes from the lower end of the toy body through the through hole.

9. The track toy as claimed in claim 8, wherein, The locking structure includes a rotating shaft, an upper extension plate, a lower extension plate, a guide post, and a compression spring. The upper and lower extension plates are respectively located at the upper and lower ends of the rotating shaft and are hinged to the toy body through the rotating shaft. The lower extension plate protrudes from the lower end of the toy body through the through hole. The guide post is horizontally arranged on the upper extension plate, and the compression spring is sleeved on the guide post. One end of the compression spring is connected to or in close contact with the upper extension plate, and the other end of the compression spring is connected to or in close contact with the toy body. The protrusion is located at the lower end of the lower extension plate.
