Description

Technical Field

[0001] The utility model relates to the technical field of toys, in particular to an assembled wheel structure for toys. Background Art

[0002] The wheel is an important component of a toy car. Most of the existing toy car wheels on the market are plastic products, that is, processed by plastic injection molding, and most of them are solid structures formed in one piece, the wheel cover cannot be disassembled and replaced, and there is no brake disc, so the decorative effect is poor, which cannot meet the personalized decoration needs. When used on a detachable toy car, the disassembly and assembly fun of the toy car is also reduced accordingly. In this regard, some solutions are provided in the prior art. For example, the combined toy injection-molded wheel with the Chinese patent publication number "CN215916460U" has a technical solution that a shaft hole is provided at the center position of the wheel body, and the outer surface of the wheel body is recessed inward to form an assembly cavity adapted to the outer contour of the wheel cover. An insertion cavity is provided at the center position of the assembly cavity. The brake disc is located in the assembly cavity, and a through hole is provided at the center position. The wheel cover covers the opening of the assembly cavity, and an insertion post that passes through the through hole and inserts into the insertion cavity is provided. A hollow position is provided on the wheel cover. From the above technical solution, it can be seen that although the solution of the prior art solves the technical problems of non-replaceable wheel cover and overall visual effect, it has problems such as cumbersome insertion structure and poor overall simulation effect because the brake disc rotates with the rotation of the wheel.

[0021] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will further describe the present utility model in detail with reference to the Figures 1 - 3 accompanying drawings.

[0022] Referring to Figure 1 as shown, an assembled wheel structure for a toy according to an embodiment of the present utility model includes a support body 1, a tire 2, a brake disc 3, a caliper 4, and a decorative cover 5.

[0023] The outer contour of the support body 1 is cylindrical. An installation cavity 11 for accommodating the brake disc 3 and the decorative cover 5 is provided inwardly on the surface of the outer end of the support body 1. A flange 12 is provided at the edge of the inner end of the support body 1.

[0024] Combined with Figure 2 as shown, an annular recess 21 that mates with the flange 12 is provided inwardly on the surface of the inner end of the tire 2, and the annular recess 21 communicates with the hollow portion of the tire 2. When the tire 2 is sleeved on the outer periphery of the support body 1, the annular recess 21 abuts against the flange 12, thereby playing a role in positioning and limiting.

[0025] Furthermore, an annular groove 22 is provided on the inner wall of the tire 2. When the tire 2 is sleeved on the support body 1, the annular groove 22 makes it easier for the tire 2 to generate a certain deformation amplitude, which is beneficial to the installation work of the tire 2.

[0026] At the center of the inner side of the brake disc 3, there is a connecting convex column 31. In this embodiment, the connecting convex column 31 and the brake disc 3 are integrally formed by an injection molding process.

[0027] A first avoidance hole position 13 is provided at the center of the surface of the inner end of the support body 1. The first avoidance hole position 13 is provided in a through manner, and its diameter is larger than the diameter of the tail section of the connecting convex column.

[0028] During operation, the tail section of the connecting convex column 31 is disposed outside the support body 1 through the installation cavity 11 and the first avoidance hole position 13, so that the brake disc 3 is located in the installation cavity 11.

[0029] Referring to Figure 2 and Figure 3 as shown, a plurality of abutting portions 33 are protrudingly provided on the surface of one side of the brake disc 3. In this embodiment, the number of the abutting portions 33 is preferably three, and the three abutting portions 33 are distributed in a U shape with the brake disc 3 as the center.

[0030] In this embodiment, the outer contour of the abutting portion 33 is semi-spherical. When the brake disc 3 is located inside the support body 1, the abutting portion 33 abuts against the inner end face of the installation cavity 11, and the abutting portion 33 supports and balances the support body 1; at the same time, the connection between the abutting portion 33 and the support body 1 is a point connection, so the contact surface is small and the friction force is also small, and when the support body 1 rotates, it has a better rotation effect.

[0031] Furthermore, the outer contour of the tail section of the connecting stud 31 is cross-shaped for plugging into the bottom of the building block vehicle.

[0032] A number of annular ridges 34 are provided on the inner surface of the brake disc 3. The a number of annular ridges 34 are concentrically arranged, and their centers are concentric with the center of the brake disc 3. In this embodiment, the diameters of the two annular ridges 34 increase outward from the center of the brake disc 3.

[0033] A clamping groove 41 is provided inwardly at the bottom of the caliper 4, and the clamping groove 41 communicates with both ends of the caliper 4. During use, the clamping groove 41 is inserted on the outer periphery of the brake disc 3, and the annular ridge 34 is clamped with the inner side surface of the clamping groove 41 to limit the caliper 4 on the brake disc 3.

[0034] Refer to Figure 1 and Figure 2 As shown, an annular clamping position 111 is provided between the inner wall of the installation cavity 11 and the open end of the support body 1, and the annular clamping position 111 communicates with the open end of the support body 1. The inner wall of the annular clamping position 111 is inclined, and the higher end of the inner wall of the annular clamping position 111 is connected to the open end of the support body 1, thereby playing a role in guiding the installation.

[0035] In this embodiment, the decorative cover 5 is C-shaped in the vertical section. A number of limiting ridges 51 are provided on the outer periphery of the decorative cover 5, and the a number of limiting ridges 51 are circumferentially distributed along the outer periphery of the decorative cover 5. The end face of the decorative cover 5 is used as a decorative part.

[0036] During use, the decorative cover 5 is inserted into the installation cavity 11 until the bottom of the decorative cover 5 abuts against the end face of the annular clamping position 111, and the a number of limiting ridges 51 are clamped with the inner wall of the annular clamping position 111 to limit the decorative cover 5 in the annular clamping position 111.

[0037] A positioning portion 52 is axially extended outward from the center of the decorative cover 5. In this embodiment, the positioning portion 52 is T-shaped in the vertical section, and the larger diameter section of the positioning portion 52 is connected to the inner end face of the decorative cover 5.

[0038] At the center of the other surface of the brake disc 3, a second avoidance hole position 35 is provided inward. The diameter of the second avoidance hole position 35 is larger than the smaller diameter section of the positioning portion 52 and smaller than the larger diameter section of the positioning portion 52. When the decorative cover 5 is located on the annular clamping position 111, the smaller diameter section of the positioning portion 52 passes through the second avoidance hole position 35.

[0039] In this embodiment, the positioning portion 52 and the second avoidance hole position 35 cooperate to play a positioning role. When it is necessary to replace the decorative cover 5 with a different shape, the connecting convex column 31 is pushed towards the open end of the support body 1 so that the side surface of the brake disc 3 abuts against the end of the larger diameter section of the positioning portion 52. As the brake disc 3 moves outwards, the decorative cover 5 is driven to disengage from the annular clamping position 111.

[0040] The overall design of this wheel structure is ingenious and reasonable. The wheel structure is composed of a split-type detachable support body, a tire, a brake disc, a caliper and a decorative cover. In terms of use, it further increases the playability of the product, and visually, the appearance of the wheel highly restores the wheel of a real car; when the tire rotates, only point contact is achieved between the brake disc and the support body, and the brake disc and the caliper remain stationary, and the visual effect is closer to that of a real car; the assembly of the decorative cover, caliper and brake disc is simple and convenient, and can meet different personalized decoration needs.

[0041] In summary, compared with the prior art, the wheel structure of this embodiment can present a better simulation decoration effect.
