Description

Technical Field

[0001] The utility model belongs to the technical field of toy cars, in particular to a toy car bottom structure and a toy track racing car. Background Art

[0002] Toy track racing is a competitive toy. In an era of rapid technological advancement, toy racing has become not only a leisurely toy for children but also an educational competition. It not only promotes teamwork but also tests both hands-on and thinking skills. For example, during racing, children need to observe with their eyes and control with their hands. Only with a high degree of eye-hand coordination can their car run fast and steadily, which helps children develop their brains and strengthen their body coordination.

[0003] When toy track racing cars are traveling at high speeds on the track, they will constantly encounter turns and bumps. In related art, the principle by which toy racing cars can travel along the track is that iron bars are provided on the track and magnets are provided on the bottom of the toy racing car. The interaction between the magnets and the iron bars enables the racing car to travel at high speed along the preset track. However, because the height position of the magnets in the prior art cannot be adjusted, when encountering non-uniform speed conditions, the centrifugal force or rapid acceleration or deceleration generated by the high-speed motion can cause the racing car to experience abnormal operation. For example, the racing car cannot follow the track turns, or it may become unstable during turns, or it may deviate from the track and rub against the track sidewalls. When such abnormal conditions occur, the racing car's speed may be reduced at the least, and in serious cases, it may derail or overturn.

[0004] Therefore, it is urgent to design an adjustable magnet height position to change the gravitational force between the bottom of the racing car and the track. Utility Model Content

DETAILED DESCRIPTION

[0028] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The following is combined with Figure 1 To the attached Figure 4 And specific embodiments discuss the present invention in detail.

[0030] like Figure 1-4 As shown, the present invention provides a toy car bottom structure, which can be assembled with the toy car body to form a toy car for children to play with. The bottom structure includes a bottom shell 1, a magnet 2 and a power assembly 3. The bottom shell 1 has an installation cavity 11 with an upper opening. The power assembly 3 is arranged in the installation cavity 11. The front ends of both sides of the bottom shell 1 are provided with rotatable front wheels 4, and the rear ends of both sides of the bottom shell 1 are provided with rotatable rear wheels 5. The power assembly 3 can drive the front wheels to rotate, or drive the rear wheels to rotate, or drive the front and rear wheels to rotate at the same time. In this embodiment, the power assembly 3 drives the rear wheels 5 to rotate as an example. The magnet 2 is movably arranged under the bottom shell 1 through the adjustment assembly 6. The adjustment assembly 6 is used to adjust the height of the magnet 2 in the vertical direction. It can be known that the toy track racing car is usually equipped with a track during play. The track is usually changeable, with uphill slopes, etc. , downhill, turning and other different road conditions. If you want the toy track car to run along the track, you need to set a magnet 2 at the bottom of the toy track car and set an iron bar (not shown in the figure) on the track. The toy track car can run quickly along the track through the attraction between the magnet 2 and the iron bar; and the size of the attraction between the magnet 2 and the iron bar will affect the driving stability of the toy track car, especially in the turning process. If the attraction is small, the driving stability is poor, and even worse, it will cause rollover. Based on this, the present application arranges the magnet 2 into an adjustable structure. During the play process, the user can appropriately adjust the attraction between the magnet 2 and the iron bar according to various road conditions during the driving process to ensure stability during the driving process.

[0031] In some embodiments, see Figure 3 、 Figure 4The adjustment assembly 6 includes a mounting seat 61 and a limiting member 62 that drives the mounting seat 61 to move vertically; one end of the limiting member 62 is clamped on the mounting seat 61, and the other end is retractably arranged on the bottom shell 1. The magnet 2 is mounted on the mounting seat 61 and moves vertically with the mounting seat 61. In other words, the mounting seat 61 is relatively fixedly arranged at one end of the limiting member 62, while the other end of the limiting member 62 is movably arranged on the bottom shell 1. The user can adjust the expansion and contraction of the limiting member 62 to achieve the up and down movement of the mounting seat 61, thereby adjusting the position of the magnet 2. When the user finds that the toy track car cannot turn along the track or is unstable during the turning process during play, the user can adjust the position of the magnet 2 through the adjustment assembly 6 to shorten the distance between it and the iron bar, thereby increasing the attraction of the toy track car to the track, making the toy track car more stable when turning. It should be noted that the limiter 62 of the present application only emphasizes its restriction on the vertical freedom of the mounting seat 61, and does not limit whether the freedom in other directions is restricted. As long as the limiter 62 can realize the up and down adjustment of the mounting seat 61, it falls within the protection scope of the present application. In other words, the limiter 62 can also be understood as a lifting component, such as the limiter 62 is a nut and screw component, but is not limited to this.

[0032] Specifically, in this embodiment, the magnet 2 is located between the front wheel 4 and the rear wheel 5. Since the power assembly 3 drives the rear wheel 5 to rotate, and the rear wheel 5 drives the front wheel 4 to rotate, the magnet 2 is arranged close to the rear wheel 5, which can maximize the stability of the rear wheel 5 during driving, and thus ensure the stability of the entire bottom structure during driving.

[0033] In some embodiments, see Figure 2The bottom 1 is provided with a raised seat 12 on both sides. The raised seat 12 protrudes outward from the side wall of the bottom shell 1, and the raised seat 12 has a certain thickness. A screw hole 121 is provided on the raised seat 12. The screw hole 121 extends from top to bottom and can pass through the raised seat 12 or not, so as to achieve a certain adjustable range; each screw hole 121 corresponds to a limit member 62, and the mounting seat 61 and the raised seat 12 are connected together by the limit member 62. Preferably, the limit member 62 is a bolt, and the nuts 621 of the two bolts are respectively clamped at the two ends of the length direction of the mounting seat 61, and the mounting seat 61 only limits the vertical freedom of the nut 621, but does not limit its rotational freedom, that is, the bolt can rotate relative to the mounting seat 61, and the stud 622 of the bolt is screwed in the screw hole 121. The mounting seat 61 is raised or lowered by adjusting the depth of the bolt in the screw hole 121, thereby achieving the raising or lowering of the magnet 2 on the mounting seat 61. As is known to all, the bottom of a toy track race car is relatively close to the ground, and the installation space for the stopper 62 is relatively small, making it unsuitable to design it into a complex structure. On the other hand, the adjustable range of the magnet 2 is usually also relatively small. Therefore, the present application uses bolts as the stopper, which has a simple structure, is easy to adjust, and has little impact on the cost of the toy track race car.

[0034] In some embodiments, see Figure 4 The mounting base 61 has slots 611 with side openings at both ends in the width direction. A notch 612 is formed at the bottom of the slot 611. The opening direction of the notch 612 is the same as that of the slot 611. The nut 621 of the bolt enters through the opening of the slot 611, while the stud 622 of the bolt enters through the opening of the notch 612. An adjustment hole 613 is formed at the top of the slot 611. The nut 621 is confined within the slot 611 and cannot be removed from the adjustment hole 613. The nut 621 is positioned directly opposite the adjustment hole 613, allowing the nut 621 to rotate freely within the slot 611. The stud 622 extends downward from the notch 612 and connects to the screw hole 121. When the height of the magnet 2 needs to be adjusted, a tool is inserted through the adjustment hole 613 to position it on the nut 621. The tool is rotated to rotate the nut 621, thereby rotating the bolt upward or downward in the screw hole 121. The present application sets the limiting member 62 as a bolt, which has a simple structure and is easy to adjust. Even children can complete the adjustment by themselves.

[0035] It should be noted that, in this embodiment, when installing the magnet 2 on the bottom of the vehicle, the magnet 2 is first installed on the mounting seat 61, and then the bolt is placed in the slot 611 through the side opening of the slot 611 and the opening of the notch 612. Finally, the two bolts installed on the mounting seat 61 are aligned with the corresponding screw holes 121 respectively, and the bolts are rotated with a tool to screw them into the screw holes 121 on the raised seat 12 to complete the installation and adjustment.

[0036] In a specific embodiment, a side of the slot 611 opposite to the opening is a limiting side wall, which limits the lateral movement of the bolt to avoid shaking during driving.

[0037] In some embodiments, a mounting slot 614 is defined in the center of the mounting base 61. This slot 614 is a through-slot extending vertically. The magnet 2 is mounted within the slot 614, with the side of the magnet 2 facing the track exposed, allowing it to interact directly with the iron bars on the track. The bottom of the slot 614 is provided with a retaining step 615, and the top of the slot 614 is provided with elastic blocks 616 on both sides. The elastic blocks 616 include hooks 6161. The magnet 2 is installed downward from the top of the slot 614 until its lower end abuts the retaining step 615 and its upper end abuts the hooks 6161 of the elastic blocks 616.

[0038] In some embodiments, see Figure 3 、 Figure 4 The center portion of the mounting base 61 is provided with an outwardly extending limiting protrusion 617, and the lower surface of the bottom shell 1 is provided with a limiting notch 13 that matches the limiting protrusion 617. The cooperation between the limiting protrusion 617 and the limiting notch 13 prevents the mounting base 61 from shaking along its length or losing engagement with the limiting member 62, thereby ensuring stability during driving.

[0039] The vehicle bottom structure of the present application is applied to a toy track racing car. By designing the magnet 2 into an adjustable structure, it is ensured that the toy track racing car can run stably when passing through complex road conditions.

[0040] In some embodiments, see Figure 1 、 Figure 2 The bottom shell 1 is detachably connected to an upper shell 7, and the power assembly 3 is disposed within a cavity defined by the bottom shell 1 and the upper shell 7. The power assembly 3 includes a motor 31, a first gear 32 connected to the motor shaft of the motor 31, and a second gear 33 meshing with the first gear 32. The second gear 33 is fixedly mounted on a power shaft 34. The two ends of the power shaft 34 extend through the shaft holes 14 on either side of the bottom shell 1 and are connected to the rear wheel 6. The shaft holes 14 on either side of the bottom shell 1 are half-holes with upper openings. The power shaft 34 can be inserted into the shaft holes 14 from the upper openings and is retained within the shaft holes 14 by the cooperation of the upper shell 7 and the bottom shell 1. It should be noted that during the continuous use of the track racing car, the power assembly 3 is a consumable item. In particular, the second gear 33 and the rear wheel 5 will wear out during long-term use, resulting in reduced playability. In this case, the upper shell 7 can be removed and replaced to improve performance and enhance playability.

[0041] In the preferred embodiment, see Figure 1The upper shell 1 is provided with downwardly extending connecting portions 71 on either side, each with a buckle hole 72. The bottom shell 1 is provided with barbed mounting protrusions 15 on either side, corresponding to the buckle holes 71. The upper shell 7 and bottom shell 1 are assembled and disassembled via a snap-fit ​​mechanism, making it quick and easy for consumers to replace the rear wheel 5, power shaft 34, and second gear 33, thereby indirectly extending the life of the toy car.

[0042] Specifically, when the buckle hole 72 is buckled onto the mounting protrusion 15, the inner side surface of the connecting portion 71 is in close contact with the outer side surface of the bottom shell 1, thereby improving the stability of the connection. Optionally, when the inner side surface of the connecting portion 71 is in close contact with the outer side surface of the bottom shell 1, a gap is formed between the lower portion of the inner side surface of the connecting portion 71 and the bottom shell 1, allowing the user's fingers to enter the gap to quickly remove the upper shell 7 from the bottom shell 1.

[0043] The present invention also provides a toy track race car comprising any of the above-mentioned toy car underbody structures. The toy track race car of the present application utilizes all of the technical solutions of all of the above-mentioned toy car underbody structure embodiments, and thus possesses at least all of the beneficial effects brought about by the technical solutions of the above-mentioned toy car underbody structure embodiments, which will not be detailed here.

[0044] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
