Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application 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, and therefore should not be construed as limiting this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them. Moreover, "above," "over," and "on top" of a second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0029] In view of the technical problems described in the background art, such as Figure 1-11 As shown, a novel toy car is provided, comprising: a toy car shell 1, the toy car shell 1 having an installation space inside; a pullback drive device 2, the pullback drive device 2 being disposed inside the toy car shell 1; a roller assembly 3, the roller assembly 3 including a drive shaft 4 and rollers 5 disposed at both ends of the drive shaft 4, the drive shaft 4 being drivenly connected to the pullback drive device 2; and ball bearings 6, the ball bearings 6 being installed inside the toy car shell 1, at least a portion of the ball bearings 6 extending beyond the bottom surface of the toy car shell 1; wherein, the ball bearings 6 and the rollers 5 form a support for the toy car shell 1.

[0030] In view of the technical problems of toy cars on the market that use four wheels as support, the above technical improvements have been made.

[0031] A novel toy car is provided. The toy car shell 1 has an internal installation space large enough to accommodate a pullback drive device 2, ball bearings 6, and a drive shaft 4. The pullback drive device 2, which can be a gear-driven pullback mechanism, is located inside the toy car shell 1. The pullback drive device 2 stores and releases kinetic energy. Its output end is connected to the drive shaft 4, driving the rollers 5 to rotate and propel the toy car forward. The pullback drive device 2 is prior art and not an improvement in this invention; therefore, it will not be described further. The ball bearings 6 are installed inside the toy car shell 1, and together with the two rollers 5, they form a support for the toy car.

[0032] In the above technical solution, by adopting a three-point support structure with a single ball bearing (6 rollers) and two double rollers (5 rollers), the number of wheel sets is reduced to two, significantly reducing material and parts procurement costs. This also reduces assembly time and improves assembly efficiency.

[0033] like Figure 7-11 As shown, the toy car shell 1 includes an upper shell 7 and a lower shell 8 disposed below the upper shell 7. The upper shell 7 includes a front shell 9 and a rear shell 10 that cooperates with the front shell 9. The front shell 9 has a first slot 11 on its inner side, the rear shell 10 has a second slot 12 on its inner shell, the lower shell 8 has a first locking part 13 at its front end that cooperates with the first slot 11, and the lower shell 8 has a second locking part 14 at its rear end that cooperates with the second slot 12.

[0034] To simplify the assembly of the toy car shell 1, reduce the number of screws, and lower costs, the first slot 11 and the second slot 12 are recessed grooves, while the first locking part 13 and the second locking part 14 are protruding structures corresponding to the contours of the grooves. The first locking part 13 of the lower shell 8 is inserted into the first slot 11, and the second locking part 14 of the lower shell 8 is inserted into the second slot 12. The front shell 9 and the rear shell 10 are then locked together with screws to complete the assembly.

[0035] By utilizing slots and clips, rapid assembly is achieved, and with the assistance of bolts for locking, assembly time is greatly reduced.

[0036] The bottom surface of the toy car shell 1 is provided with a ball groove 15 for installing the ball bearing 6, and the ball groove 15 has a downward-facing opening. The ball groove 15 facilitates the installation of the ball bearing 6.

[0037] Furthermore, the return drive device 2 includes a mounting shell 16 extending to the position of the ball 6, which is used to fix the ball 6 within the ball groove 15. To limit the movement of the ball 6 within the ball groove 15, the mounting shell 16 is used to confine the ball 6 within the ball groove 15, simplifying the structural design.

[0038] Specifically, the lower shell 8 has a third slot 17 on its front wall at the position of the bead groove 15, and the front end of the mounting shell 16 has a third locking part 18 that mates with the third slot 17. By placing the third locking part 18 into the third slot 17, one end of the mounting shell 16 is fixed, and the other end of the mounting shell 16 can be fixed to the lower shell 8 with screws, reducing the number of screws and simplifying the installation operation of the mounting shell 16.
