Description

Technical Field

[0002] A related technology provides a magnetic frame with a cubic structure. Each of its eight corners is equipped with a magnetic component, and adjacent frames are fixed together by the magnetic attraction of their corresponding corner components. However, when this type of magnetic frame is used to assemble tracks in toy cars, it relies solely on the attraction force of the magnetic components to maintain stability. Adjacent frames are prone to separation or relative displacement after assembly, leading to a loose track structure. This severely impacts the normal play experience of the toy car, failing to meet users' needs for track assembly stability and smooth gameplay, resulting in a poor user experience.

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

Detailed Implementation

[0043] 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.

[0044] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0045] 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.

[0046] Example 1: See Figures 1 to 4As shown, Embodiment 1 of this application provides a magnetic frame assembly, including: multiple magnetic frames 2 and reinforcing members 3. The magnetic frame 2 includes a three-dimensional frame with six annular side plates 2a. Each annular side plate 2a encloses a central hollow opening 2a1. Magnetic components (not shown) are provided at each of the eight corners of the three-dimensional frame. The annular side plates 2a of two magnetic frames 2 that are magnetically attracted are in contact with each other. The reinforcing member 3 is detachably connected to two adjacent magnetic frames 2. The reinforcing member 3 is located on the central hollow opening 2a1 and has two limiting portions 31. When the reinforcing member 3 is connected to the magnetic frame 2, the two limiting portions 31 are respectively limited to the opposite sides of the two contacting annular side plates 2a. The magnetic frame assembly of this application forms a bidirectional limit on the two adjacent magnetic frames 2 through the reinforcing member 3, and achieves double fixation with magnetic attraction. It effectively solves the problem of easy separation and displacement of adjacent magnetic frames 2 in related technologies, and significantly improves the stability of the track toy assembly, the smoothness of the ride and the safety of playing, and provides a better user experience.

[0047] In one possible implementation, such as Figure 2 As shown, the reinforcing member 3 has a connecting body 32, which connects to two limiting parts 31 respectively. A slit is formed between the two limiting parts 31, and the two annular side plates 2a that are in contact with each other can be inserted into the slit. The thickness of the slit is approximately the same as the total thickness of the two annular side plates 2a that are in contact with each other. The slit of the reinforcing member 3 can be fitted onto the two annular side plates 2a after they are in contact. This not only restricts the movement of the magnetic frame 2 along the direction perpendicular to the contact surface, but also prevents adjacent magnetic frames 2 from shaking with each other through a tight fit.

[0048] Both of the two limiting parts 31 have a flat surface on their opposite sides, which can fit into the surface of the annular side plate 2a. The flat surface improves the fit and contact area, and also enhances the stability and reliability of the limiting, avoiding gaps or displacement caused by poor fit, further improving the limiting effect on adjacent magnetic frames 2, ensuring the firmness of the track splicing, and improving the play experience.

[0049] In one possible implementation, such as Figure 2 As shown, the two limiting portions 31 have recessed portions 311 on the side opposite to the connecting body 32. That is, the limiting portions 31 are hollow cavity structures, which can effectively reduce weight and save raw material costs. Moreover, due to the hollow thin-walled design, they can meet the needs of injection molding, optimize melt filling and cooling efficiency, reduce molding defects, and improve processing convenience and product qualification rate. This also meets the lightweight and easy-to-operate usage requirements of the magnetic frame assembly of this application.

[0050] In one possible implementation, such as Figure 2As shown, each of the two limiting parts 31 has a protruding strip 33 on one side facing away from each other. The protruding strip 33 makes it easier for the operator to pinch and apply force, increases the frictional resistance between the hand and the surface of the limiting part 31, effectively solves the problem of slipping on smooth surfaces, and improves the stability and convenience of holding during operation. It is especially suitable for the use of children's toys, allowing children to easily complete the pinching operation.

[0051] In the three-dimensional frame, an angular space is formed between two perpendicular annular side plates 2a, and the limiting part 31 is accommodated within the angular space. The circumferential and axial limiting effect of the angular space can accurately position the installation position of the limiting part 31, preventing it from shifting or shaking during use and improving the stability of the structural assembly.

[0052] like Figure 1 As shown, two baffles 2a2 are provided at intervals on the inner wall of the annular side plate 2a. When the reinforcing member 3 is connected to two adjacent magnetic frames 2, the limiting part 31 is located between the two baffles 2a2, forming a bidirectional limiting in the up-down or left-right direction for the limiting part 31 located therebetween, which significantly improves the limiting stability and structural positioning accuracy.

[0053] like Figure 1 and Figure 3 As shown, the magnetic frame 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 connectors 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.

[0054] 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 connector 22 can be made of plastic and are welded into a fixed, integrated structure using ultrasonic welding equipment, resulting in 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 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.

[0055] like Figure 3 and Figure 4 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 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.

[0056] In one possible implementation, such as Figure 3 and Figure 4 As shown, a positioning rib 2221 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 connector 22 and the main frame 21 are connected, the positioning rib 2221 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.

[0057] like Figure 4 As shown, the insert 221 is a cylindrical shaft, one end of the positioning rib 2221 extends to the surface of the cylindrical shaft and is connected to the cylindrical shaft, and the extension line of the positioning rib 2221 passes through the center line of the cylindrical shaft.

[0058] Example 2: See Figure 5 and Figure 10As shown, Embodiment 2 of this application also provides a track toy, including: a magnetic frame assembly as described above, multiple track blocks 1, and a toy car 4. The magnetic frames 2 of the magnetic frame assembly are arranged to form different shapes. Each track block 1 is detachably connected to its corresponding magnetic frame 2. Magnetic strips 11 are provided on each track block 1, and the magnetic strips 11 of each track block 1 are connected sequentially. The toy car has a drive mechanism and magnetic wheels. The magnetic wheels are supported by the magnetic strips 11, and the magnetic wheels and magnetic strips 11 are magnetically attracted to each other. The drive mechanism is connected to the magnetic wheels to drive the magnetic wheels to rotate. This application's track toy, through the splicing of the magnetic frames 2 and the detachable connection of the track blocks 1, allows for flexible changes in the toy's shape, enhancing its fun. The magnetic wheels attract the magnetic strips 11 of the track, and the drive mechanism ensures stable and autonomous operation of the toy car. The overall assembly is convenient and the structure is stable, which can exercise children's hands-on ability and is easy to operate.

[0059] The track block 1 has an annular rib 12. When the track block 1 is connected to the magnetic frame 2, the annular rib 12 is embedded in the central cutout 2a1 of the magnetic frame 2. The annular rib 12 is precisely matched to the central cutout 2a1 in shape and size. When the track block 1 is connected to the magnetic frame 2, the annular rib 12 can be tightly embedded in the central cutout, which not only ensures assembly stability but also simplifies disassembly and assembly operations, improving ease of use and structural reliability.

[0060] In one possible implementation, some track blocks 1 have a flat mounting surface 13, and some track blocks 1 have an arc-shaped curved mounting surface 13. A groove 131 is provided on the mounting surface 13, and the magnetic strip 11 is embedded in the groove 131. The arc-shaped curve can be either convex or concave. The overall shape of the track block 1 can include various types such as straight, triangular, fan-shaped, and semi-circular. The shape of its mounting surface 13 is adapted to the overall structural design and can be arranged in diverse ways. Furthermore, the mounting surfaces 13 of adjacent track blocks 1 can be smoothly joined, ensuring the continuity of the track toy's connection.
