Description

Technical Field

[0001] This utility model relates to the field of toy technology, specifically to a track assembly and a track toy. Background Technology

[0002] Existing track toys mainly consist of several magnetic frames and track components, with each track component containing multiple track pieces. During actual assembly, the magnetic frames attract each other to form a track support. Each track piece rests on this support, and at least two track pieces connect to form a complete track. Some track pieces penetrate the magnetic frames, are snapped into the middle, and extend out of the frames at one or both ends, resulting in some parts of the track piece being located on the outside of the magnetic frame and others on the inside. There are also track pieces that are entirely located on the outside of the magnetic frame. When different types of track pieces connect to form a complete track, the small size of each track piece and the lack of effective support points at the connection points between adjacent pieces lead to poor stability and a tendency for the track to fall apart, resulting in a poor user experience.

[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0049] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0050] Example 1: See Figures 6 to 13As shown, Embodiment 1 of this application provides a track assembly 1, including: a plurality of inner tracks 11 and a plurality of outer tracks 12. The inner tracks 11 have an inner track shell 111 and insertion seats 112 disposed at both ends of the inner track shell 111 along its length direction, the protruding direction of the insertion seats 112 being perpendicular to the extending direction of the inner track shell 111. The outer tracks 12 include an outer track shell 121, a bonding plate 122, and frame connecting blocks 123. The bonding plate 122 is disposed at at least one end of the outer track shell 121, and the bonding plate 122 has a clearance notch to avoid the track groove of the outer track shell 121. Only two frame connecting blocks 123 are disposed on the side of the bonding plate 122 facing away from the outer track shell 121, with the two frame connecting blocks 123 respectively disposed on both sides of the bonding plate 122. Multiple inner tracks 11 and multiple outer tracks 12 can be connected to a support structure composed of multiple magnetic frames 2. The inner tracks 11 are located inside the magnetic frames 2, and the outer tracks 12 are located outside the magnetic frames 2. Several inner tracks 11 and several outer tracks 12 can be assembled to form a complete track. The complete track is a structurally connected track, and multiple complete tracks can be installed on the support structure composed of multiple magnetic frames 2. The inner tracks 11 of the track assembly 1 of this application can be plugged into the inner side of the magnetic frames 2 for stable installation. The outer tracks 12 can be directly connected to the magnetic frames 2 via frame connecting blocks 123, allowing the magnetic frames 2 to provide stable support for the outer tracks 12, greatly improving the stability of the connection structure and significantly enhancing the structural stability of the track toy, providing users with a better assembly and usage experience.

[0051] like Figure 6 , Figure 7 and Figure 8 As shown, the inner track 11 includes: a unidirectional straight track 11a, a unidirectional curved track 11b, and a multidirectional straight track 11c. The unidirectional straight track 11a extends in a straight line, and each end of the unidirectional straight track 11a has a connector 112 at its bottom. The unidirectional curved track 11b extends along an arc, and each end of the unidirectional curved track 11b has a connector 112 at its bottom, with the two connectors 112 being perpendicular to each other. The multidirectional straight track 11c includes four track segments, with one end connected and the other ends extending in different directions. Each track segment has a connector 112 at its bottom. During assembly, users can use the unidirectional straight track 11a, the unidirectional curved track 11b, and the multidirectional straight track 11c to assemble different shapes, which is beneficial for developing children's thinking and hands-on abilities.

[0052] In one possible implementation, such as Figure 8As shown, the multi-directional straight track 11c includes two sub-shells with identical shapes, which are joined together to form a complete multi-directional straight track 11c. If the multi-directional straight track 11c were a single integral structure, its size would be too large to fit inside the magnetic frame 2 when installed. By configuring the multi-directional straight track 11c as two sub-shells, the structure is simplified and the size is reduced. During installation, one sub-shell can be installed inside the magnetic frame 2 first, followed by the installation of the other sub-shell. The smaller size of the sub-shells facilitates insertion into the magnetic frame 2, making the installation of the multi-directional straight track 11c simple, convenient, quick, and efficient.

[0053] like Figure 1 and Figure 11 As shown, one end of the outer track 12 is provided with a bonding plate 122, and the other end is provided with a funnel shell 124, with a drop opening 1241 in the middle of the funnel shell 124. When the track is set up for play, the balls or rollers that enter the funnel shell 124 can fall through the drop opening 1241 onto another complete track.

[0054] In one possible implementation, such as Figure 1 and Figure 13 As shown, the track assembly 1 includes a centrifugal shell 13 with a drop hole 131. The centrifugal shell 13 can be supported on the magnetic frame 2 and is used to guide objects so that objects leaving through the drop hole 131 enter the complete track. The objects can be spheres or ball bearings.

[0055] Example 2: See Figures 1 to 14 As shown, Embodiment 2 of this application also provides a track toy, including: multiple magnetic frames 2 and a track assembly 1 as described above. Each magnetic frame 2 is attracted and connected to form a support, and each magnetic frame 2 has a cavity. Multiple openings communicating with the cavities are provided on the magnetic frame 2. Several inner tracks 11 of the track assembly 1 are disposed inside the corresponding magnetic frames 2 and are inserted into the inner track fixing slots on the magnetic frames 2 via connectors 112. Several outer tracks 12 of the track assembly 1 are disposed outside the magnetic frames 2 and are inserted into the outer track fixing slots 2113 on the magnetic frames 2 via frame connecting blocks 123. The multiple inner tracks 11 and multiple outer tracks 12 on the support can be assembled to form a complete track.

[0056] In one possible implementation, such as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the magnetic frame 2 includes two main frames 21 and four connectors 22. The two main frames 21 are structurally identical, each including a side frame 211 and four extending protrusions 212. Each extending protrusion 212 is located at one of the four corners of the side frame 211 and is perpendicular to the side frame 211. Each extending protrusion has a slot 2121, and each slot 2121 accommodates a magnetic component. Each connector 22 has a post 221 at both ends. The posts 221 at both ends of each connector 22 are inserted into the slots 2121 of two opposite extending protrusions 212 on the two main frames 21, and the connector 22 closes the opening of the slots 2121. The two main frames 21 and the four connectors 22 are welded together using ultrasonic welding equipment to form an integral structure, allowing each magnetic component to be freely rotated and accommodated within the slots 2121. The two main frames 21 and the four connecting bodies 22 are welded and fixed together by ultrasonic welding equipment to form an integrated structure. The integrated structure has the appearance of a cube-shaped frame structure.

[0057] The ultrasonic welding process involves the welding head contacting the object to be welded. Under pressure, high-frequency vibrations are transmitted to the contact surface of the object. Due to the high vibration frequency, the molecules on the object's surface undergo violent movement, generating heat through friction. This heat causes the material on the object's surface to reach its melting or softening point. Simultaneously, under pressure, the molecules on the two object surfaces permeate and diffuse, forming intermolecular bonds, thus achieving welding. After welding is completed, vibration and pressure are stopped, and the welded area cools to form a strong connection. This connection structure is highly stable and cannot be disassembled. The main frame 21 and the connecting body 22 can be made of plastic parts, welded together using ultrasonic welding equipment to form a fixed, integrated structure with excellent structural stability. During the assembly of multiple magnetic frames 2 to form a track toy, the magnetic components within each magnetic frame 2 can freely rotate and automatically adjust their positions. Precise alignment is not required between two assembled magnetic frames 2; the corresponding magnetic components can automatically adhere to their positions, reducing assembly difficulty and making it especially suitable for younger children, saving time and effort. The magnetic frame 2 is an integral structure with good structural stability, and is not prone to disintegration or cracking. It also eliminates the need for tedious assembly operations, greatly saving time and effort, allowing users to quickly get into a playful state, and enhancing the product's attractiveness and usability.

[0058] like Figure 1 and Figure 2As shown, the magnetic frame 2 has six faces and twelve edges. Each face has a cutout and an outer track fixing groove 2113, and each edge has an inner track fixing groove. The inner track 11 and the outer track 12 are in contact and connected at the cutout. The insertion seats 112 at both ends of the inner track 11 are inserted into the inner track fixing grooves on the corresponding edges.

[0059] In each of the surfaces of the magnetic frame 2, four outer track fixing slots 2113 are provided on two opposite surfaces, with each outer track fixing slot 2113 on each surface located near one of the four corners of the corresponding surface. When the outer track 12 and the magnetic frame 2 are connected, the bonding plate 122 of the outer track 12 is bonded to the corresponding surface, and the two frame connecting blocks 123 on the bonding plate 122 are respectively inserted into the two outer track fixing slots 2113 on the same surface of the magnetic frame 2.

[0060] like Figure 4 and Figure 5 As shown, the connector 22 includes a central body 222, with insertion posts 221 disposed on both sides of the central body 222. The insertion posts 221 are inserted into the slots 2121 of the corresponding extension protrusions 212, and the central body 222 covers the opening of the slots 2121 of the extension protrusions 212. The end of the central body 222 is limited to the opening of the slots 2121.

[0061] like Figure 2 and Figure 4 As shown, the central body 222 includes two end pieces 2221 and two side pieces 2222. The two insertion posts 221 of the connecting body 22 are respectively vertically connected to the corresponding end pieces 2221. The two side pieces 2222 are vertically connected and located between the end pieces 2221, and the side pieces 2222 are respectively vertically connected to the two end pieces 2221. With the connector 22 and the main frame 21 connected, the insert 221 is inserted into the slot 2121 of the corresponding extension protrusion 212. The end piece 2221 fits against the end of the extension protrusion 212 and covers the slot 2121. The two side pieces 2222 are smoothly spliced ​​with the two shell walls perpendicular to the extension protrusion 212. The smooth splicing forms a smooth weld. The smooth weld is then welded using an ultrasonic device. The welding is convenient and the welding effect is good, so that the overall appearance of the magnetic frame 2 of this application presents a unified effect. The surface of the magnetic frame 2 has no protruding structure and the appearance is beautiful.

[0062] An inner track fixing groove is formed between the two end pieces 2221 of the central body 222. The inner track fixing groove is used to fix the track assembly 1 in the track toy.

[0063] In one possible implementation, such as Figure 2 , Figure 4 and Figure 5 As shown, a positioning rib 2223 is provided at the end of the middle body 222, so a positioning notch 2122 is provided on one side of the slot 2121 of the extended protrusion 212. When the connecting body 22 and the main frame 21 are connected, the positioning rib 2223 is inserted into the positioning notch 2122. This makes the connection between the middle body 222 and the main frame 21 easier to align and improves the assembly accuracy.

[0064] like Figure 5 As shown, the insert 221 is a cylindrical shaft, and one end of the positioning rib 2223 extends to the surface of the cylindrical shaft and connects to it. The extension line of the positioning rib 2223 passes through the center line of the cylindrical shaft. The end piece 2221 has a square structure, and the positioning rib 2223 extends from one corner of the end piece 2221 to the surface of the cylindrical shaft and connects to it, increasing the structural strength of the cylindrical shaft.

[0065] like Figure 4 As shown, the side frame 211 includes four frame edges arranged sequentially along the circumference. An extension protrusion 212 is provided between two adjacent frame edges, and an inner track fixing groove is provided in the middle of each frame edge. The four frame edges together form a square structure of the side frame 211, and an extension protrusion 212 is provided at each of the four corners of the side frame 211.

[0066] like Figure 4 As shown, the frame edge includes two partitions 2111 and two strips 2112 that are perpendicularly connected to each other. The two partitions 2111 are arranged sequentially along the length direction of the strips 2112, and the partitions 2111 are respectively connected to the two strips 2112. The inner track fixing groove is formed between the two partitions 2111.

[0067] In one possible implementation, such as Figure 2 As shown, an outer track fixing groove 2113 is provided on the outer surface of the side frame 211. The outer track fixing groove 2113 is used to connect the outer track 12.

[0068] like Figure 2 and Figure 3As shown, the outer track fixing groove 2113 is an isosceles trapezoid. A tight-fitting protrusion 2113a is provided on the inner wall of the outer track fixing groove 2113. A guide slope is provided on the side of the tight-fitting protrusion 2113a near the opening of the outer track fixing groove 2113. When the frame connecting block 123 is inserted into the outer track fixing groove 2113, the tight-fitting protrusion 2113a fits tightly against the frame connecting block 123. The guide slope guides the frame connecting block 123 to slide along the guide slope, facilitating the smooth insertion of the frame connecting block 123 into the outer track fixing groove 2113. The tight-fitting protrusion 2113a ensures a tight fit between the frame connecting block 123 and the outer track fixing groove 2113, resulting in a better fit between the outer track 12 and the magnetic frame 2, making it less prone to disintegration and collapse.

[0069] like Figure 13 As shown, an annular retaining edge 132 is provided on the outer surface of the centrifugal shell 13 of the track assembly 1 around the drop hole 131. When the centrifugal shell 13 and the magnetic frame 2 are connected, the annular retaining edge 132 is inserted into the hollow opening of the magnetic frame 2. The plug-in fit is simple in structure and easy to connect. After connection, the centrifugal shell 13 can be stably supported on the corresponding magnetic frame 2.

[0070] In one possible implementation, such as Figure 14 As shown, the magnetic frame 2 includes a sealing plate 23, and an annular rib 231 is provided on one side of the sealing plate 23 along its thickness direction. The sealing plate 23 can be attached to any surface of the magnetic frame 2, and the annular rib 231 is inserted into the corresponding cutout on the surface. The magnetic frame 2 has a cubic structure, and the sealing plate 23 can cover the cutout, making the magnetic frame 2 of this application aesthetically pleasing. The sealing plate 23 can be welded to and fixed to any surface of the magnetic frame 2, or it can be inserted and fixed.

[0071] The preferred embodiments disclosed above are merely illustrative of this application. These preferred embodiments do not exhaustively describe all details, nor do they limit the application to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
