Description

Technical Field

[0001] This utility model relates to the field of toys, and in particular to a track toy. Background Technology

[0002] Track toys consist of the toy body and the track body. The track body is usually composed of multiple different track units, which can be freely combined to form different complete tracks, effectively developing children's hands-on skills and stimulating their thinking. Currently, track units are only available in a limited variety, such as straight, sloping, or curved types. These track units have a relatively simple structure. Although they can be combined in various ways to form different complete tracks, to build the most complex tracks possible within a limited space, the tracks usually have intersecting areas. These intersecting areas are generally constructed by staggering the upper and lower track segments. This method requires the distance between the upper and lower track segments to be at least the height of the toy body. This not only requires track units with large curvatures but also a large number of track units, and additional supports to elevate the upper track segments. This assembly method has high requirements for the number, shape, and strength of the track units, presenting a certain barrier to entry and incurring high costs. For smaller track toys suitable for younger children, there are generally fewer parts, resulting in less versatility in assembly, less playability, and difficulty in maintaining children's interest. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a track toy that can be freely assembled into tracks of various shapes as needed, and only a single intersecting track unit is needed to assemble a track with intersecting track segments, thus having higher assembly versatility.

[0004] To solve the above technical problems, the following technical solution is adopted: A track toy includes a track body and a toy body. The track body includes multiple basic track units, each of which is provided with a guide rail arranged in a front-to-back direction. The toy body is provided with a power mechanism that can move along the guide rails. The track body is characterized in that: the track body also includes at least one intersecting track unit, which is provided with two guide rails. The two guide rails are intersected to form a cross shape and form an intersecting guide rail segment at the intersection. The intersecting guide rail segment is composed of four guide rail protrusions arranged in a rectangular array.

[0005] The aforementioned basic track units typically include common track units such as straight track units, turning track units, and undulating track units. When playing with these track toys, the various basic track units and intersecting track units are first assembled into tracks of different shapes. During assembly, intersecting track segments can be directly connected through intersecting track units. After assembly, the toy body can be placed on the track, and the toy body's power mechanism drives it to move along the guide rails. Because the intersecting guide rail segments are composed of guide rail protrusions, adjacent guide rail protrusions can form a guide rail segment for the power mechanism to move, ensuring that the guide rail protrusions maintain engagement with each other when the toy body passes through. Simultaneously, the spacing between the guide rail protrusions ensures that they do not obstruct the toy body when passing through from the intersecting direction. This type of track toy can be freely assembled into various shapes of tracks as needed. Furthermore, when assembling tracks with intersecting track segments, only a single intersecting track unit is needed to achieve the intersecting assembly, without the need for staggered vertical arrangement. This reduces the requirements for the number and shape of other track units, resulting in greater assembly versatility.

[0006] The aforementioned forward and backward directions are determined based on the position of the toy body as it travels on the track unit. The position the toy body passes through first is considered backward, and the position it passes through last is considered forward.

[0007] In the preferred embodiment, 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, and 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 locking structures, and the lower end of the locking structure has an outwardly protruding part that matches the slot. After the track is assembled, the toy body is placed on the track. When placed, the lower ends of the two locking structures extend into the guide groove, and the protrusions engage in the slots. With this structure, regardless of the track assembly, the toy body can always be in contact with the track and move along the track. The aforementioned up-down direction is determined by the position of the toy body when it travels on the track unit; the position of the toy body closer to the guide rail is down, and the position farther from the guide rail is up.

[0008] In a further preferred embodiment, 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. Typically, the cross area is the area without guide groove walls, only the guide rails.

[0009] In a further preferred embodiment, guide block groups are provided along the four perimeters of the intersection area. Each guide block group includes at least two guide blocks, each guide block comprising a vertical segment and a horizontal segment. The vertical segment is positioned along the bottom wall of the guide groove and on the side of the corresponding guide rail. One end of the horizontal segment connects to the upper end of the vertical segment, and the other end of the horizontal segment faces the intersection guide rail segment and is flush with the groove wall of the guide groove. A gap exists between each guide block and the groove wall of the adjacent guide groove, the gap being larger than the thickness of the locking block structure. When the toy body passes through the intersection area, the area enclosed by the vertical and horizontal segments of the guide blocks functions similarly to a locking groove, engaging with the protrusion to limit and guide the toy body, without obstructing its passage from the intersection direction.

[0010] In a further preferred embodiment, the guide rail is a rack and pinion; the power mechanism includes a power source, a motor, and a gear set. The power source is electrically connected to the motor, and the motor's output shaft 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, with the protruding portion of the last gear of the gear set positioned between the two locking blocks. Typically, the toy body also has a switch; when the switch is turned on, the motor drives the last gear of the gear set to rotate, thereby moving the toy body along the guide rail.

[0011] In a further preferred embodiment, the distance between two adjacent guide rail protrusions is the same as the tooth pitch of the last stage gear of the gear set.

[0012] In a further preferred embodiment, 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 sidewalls of the guide groove are both arc-shaped. With this structure, when the toy body needs to be placed on the track or removed from the track, only slight force is required to allow the protrusion to pass over the guide groove wall and engage or disengage from the slot, minimizing wear. The aforementioned inward and outward directions are determined based on the direction of the guide rail when the toy body travels on the track unit; the direction closer to the guide rail is inward, and the direction farther from the guide rail is outward.

[0013] In a further preferred embodiment, 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.

[0014] In a further preferred embodiment, 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 via 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 positioned 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 is connected to or in close contact with the toy body. The protrusion is located at the lower end of the lower extension plate. When the toy body needs to be placed on the track or removed from the track, only a slight force is needed to swing the rotating shaft, allowing the protrusion to smoothly pass over the groove wall of the guide groove and engage in or disengage from the locking slot. Subsequently, under the action of the compression spring, the locking structure returns to its initial state, which further reduces wear and prevents the toy body from falling off during movement.

[0015] The beneficial effects of this utility model are that this track toy can be freely assembled into tracks of various shapes as needed, and only a single intersecting track unit is needed to assemble a track with intersecting track segments, which has higher splicing diversity.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figure 1-5 The toy shown includes a track body and a toy body 1. The track body includes a cross track unit 2 and multiple basic track units 3. Each basic track unit 3 is provided with a guide rail 4 arranged in the front-back direction. The toy body 1 is provided with a power mechanism 101 that can move along the guide rail 4. The cross track unit 2 is provided with two guide rails 4, which are arranged in a cross shape and form a cross guide rail segment 5 at the intersection. The cross guide rail segment 5 is composed of four guide rail protrusions 501 arranged in a rectangular array.

[0018] The aforementioned basic track unit 3 includes straight track units, turning track units, and undulating track units. When playing with the track toy, the various basic track units 3 and intersecting track units 2 are first assembled into tracks of different shapes. During assembly, intersecting track segments can be directly connected through the intersecting track units 2. After assembly, the toy body 1 can be placed on the track, and the power mechanism 101 on the toy body 1 drives the toy body 1 to move along the guide rail 4. Since the intersecting guide rail segments 5 are composed of guide rail protrusions 501, two adjacent guide rail protrusions 501 can form a guide rail 4 segment for the power mechanism 101 to move, ensuring that the guide rail protrusions 501 maintain engagement with each other when the toy body 1 passes through. Simultaneously, the spacing between the guide rail protrusions 501 ensures that it does not obstruct the toy body 1 when it passes through from the intersecting direction. This track toy can be freely assembled into tracks of various shapes as needed. When assembling tracks with intersecting track segments, only a single intersecting track unit 2 is needed to achieve the intersecting assembly, without the need for staggered vertical arrangement. It has lower requirements for the number and shape of other track units, resulting in greater assembly diversity.

[0019] The aforementioned forward and backward directions are determined by the position of the toy body 1 when it travels on the track unit. The position that the toy body 1 passes through first is the back, and the position that it passes through last is the front.

[0020] Each basic track unit 3 has a guide groove 6 arranged in the front-to-back direction. A guide rail 4 is positioned in the middle of the bottom wall of the guide groove 6. Each side wall of the guide groove 6 has a slot 601 extending along its length. The lower surface of the toy body 1 has two downward-extending locking structures 7. The lower end of each locking structure 7 has an outwardly protruding portion 701 that matches the slot 601. After the track is assembled, the toy body 1 is placed on the track. During placement, the lower ends of the two locking structures 7 extend into the guide groove 6, and the protrusions 701 engage in the slots 601. This structure ensures that regardless of the track assembly, the toy body 1 remains in contact with the track and moves along it during operation. The aforementioned up-and-down directions are determined by the position of the toy body 1 on the track unit; the position closer to the guide rail 4 is considered down, and the position further away from the guide rail 4 is considered up.

[0021] The cross track unit 2 is provided with two guide grooves 6 and two guide rails 4. The guide grooves 6 and guide rails 4 correspond one-to-one. The two guide grooves 6 are arranged in a cross shape and form a cross area at the intersection. The two guide rails 4 are arranged along the length direction of the corresponding guide grooves 6, and the two guide rails 4 form a cross guide rail segment 5 in the cross area. The cross area is the area without the groove walls of the guide grooves 6, only the guide rails 4.

[0022] Guide block groups 201 are provided around the four perimeters of the intersection area. Each guide block group 201 includes two guide blocks 2011. Each guide block 2011 includes a vertical section and a horizontal section. The vertical section is set on the bottom wall of the guide groove 6 in the vertical direction and is located on the side of the corresponding guide rail 4. 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 5 and is flush with the groove wall of the guide groove 6. There is a gap between each guide block 2011 and the groove wall of the adjacent guide groove 6. The size of the gap is greater than the thickness of the locking block structure 7. When the toy body 1 passes through the intersection area, the area enclosed by the vertical and horizontal sections of the guide blocks 2011 can play the same role as the locking groove 601. By engaging with the protrusion 701, it limits and guides the toy body 1, and does not cause obstruction when the toy body 1 passes through the intersection direction.

[0023] The guide rail 4 is a rack and pinion mechanism; the power mechanism 101 includes a power source, a motor, and a gear set. The power source is electrically connected to the motor, and 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 1 and meshes with the guide rail 4. The portion of the last gear of the gear set protruding from the toy body 1 is positioned between two locking structures 7. A switch is also provided on the toy body 1. When the switch is turned on, the motor drives the last gear of the gear set to rotate, thereby moving the toy body 1 along the guide rail 4.

[0024] The spacing between two adjacent guide rail protrusions 501 is the same as the tooth pitch of the last stage gear of the gear set.

[0025] The upper side of the protrusion 701 slopes outward from top to bottom, and the lower side of the protrusion 701 slopes outward from bottom to top. The upper and lower edges of the sidewalls of the guide groove 6 are both arc-shaped. With this structure, when the toy body 1 needs to be placed on the track or removed from the track, only slight force is required to allow the protrusion 701 to pass over the groove wall of the guide groove 6 and engage in or disengage from the slot 601, minimizing wear. The aforementioned inward and outward directions are determined according to the direction of the guide rail 4 when the toy body 1 travels on the track unit; the direction closer to the guide rail 4 is inward, and the direction farther from the guide rail 4 is outward.

[0026] The toy body 1 has a through hole, the locking structure 7 is hinged to the toy body 1, and the lower end of the locking structure 7 protrudes from the lower end of the toy body 1 through the through hole.

[0027] The locking structure 7 includes a pivot 702, an upper extension plate 703, a lower extension plate 704, a guide post 705, and a compression spring (not shown in the figure). The upper extension plate 703 and the lower extension plate 704 are respectively disposed at the upper and lower ends of the pivot 702 and are hinged to the toy body 1 through the pivot 702. The lower extension plate 704 protrudes from the lower end of the toy body 1 through the through hole. The guide post 705 is horizontally disposed on the upper extension plate 703. The compression spring is sleeved on the guide post 705. One end of the compression spring is connected to or in close contact with the upper extension plate 703, and the other end of the compression spring is connected to or in close contact with the toy body 1. The protrusion 701 is disposed at the lower end of the lower extension plate 704. When the toy body 1 needs to be placed on the track or removed from the track, only a little force is needed to make the rotating shaft 702 swing, so that the protrusion 701 can smoothly pass over the groove wall of the guide groove 6 and be engaged in or disengaged from the slot 601. Then, under the action of the compression spring, the locking structure 7 returns to its initial state, which can further reduce wear and prevent the toy body 1 from falling off when moving.
