Description

Technical Field

[0001] This utility model relates to the field of children's toy technology, specifically to an anti-tipping structure for plastic toy cars. Background Technology

[0002] Plastic toy cars are popular with children, but existing products have significant shortcomings in anti-tipping performance. Currently, plastic toy cars are prone to tipping over during children's play due to improper operation, uneven surfaces, or sudden turns. This not only affects the play experience but may also damage parts and reduce the lifespan of the toy car. Although some toy cars on the market have attempted to incorporate anti-tipping structures, the designs are simple. Relying solely on adding counterweights makes it difficult to flexibly handle different tilting states. Furthermore, the connection between the anti-tipping components and the car body lacks adjustability, making it unsuitable for diverse play scenarios. Moreover, the anti-tipping components do not automatically reset after tipping over, failing to effectively solve the problem of toy cars easily tipping over. Utility Model Content

[0003] An embodiment of this utility model provides a plastic toy car anti-tipping structure, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides a plastic toy car anti-tipping structure, including a plastic toy car body, two flip-connecting components, an elastic reset component, and an arc-shaped anti-tipping frame. The toy car body has mounting slots on both sides of its frame, and the two flip-connecting components are correspondingly installed in these slots. Each flip-connecting component has a limiting component at its top for flipping and limiting its movement. The elastic reset component is connected to the flip-connecting components via a damping pull-out telescopic rod. The elastic reset component includes a mounting base installed at one end of the damping pull-out telescopic rod. The anti-tipping frame is installed in a snap-fit ​​groove on the mounting base, and the height of the anti-tipping frame relative to the ground is adjustable.

[0005] As a preferred embodiment of this utility model, the flip connection assembly includes a U-shaped seat fixedly installed in the mounting groove, and a connecting block is rotatably installed inside the U-shaped seat through a damping pin. One end of the connecting block is fixedly connected to the damping pull-out telescopic rod.

[0006] As a preferred embodiment of this utility model, the limiting component includes a cover plate that is hinged to a groove on one side of the mounting groove by means of a hinge. The bottom of the cover plate is fixedly connected to a limiting block for limiting the damping pull-out telescopic rod to a horizontal state and cooperating with the pressing connecting block for limiting. The surface of the cover plate is provided with a limiting groove for locking and limiting the damping pull-out telescopic rod to a vertical state.

[0007] As a preferred embodiment of this utility model, the elastic reset assembly includes a reset torsion spring fitted to one end of the damping pull-out telescopic rod, and the reset torsion spring and one end of the damping pull-out telescopic rod are placed inside the mounting base, and one end of the reset torsion spring is fixedly connected to the damping pull-out telescopic rod, and the other end of the reset torsion spring is fixedly connected to the mounting base. The bottom of the mounting base is also provided with a clearance groove between the two snap-fit ​​grooves.

[0008] As a preferred embodiment of this utility model, the arc-shaped anti-tipping frame includes two arc-shaped plates respectively placed inside two snap-fit ​​grooves, and multiple guide rollers are rotatably installed between the two arc-shaped plates. The outer sides of the two arc-shaped plates are abutted and fixed by manual bolts that are threadedly connected to the mounting seat.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. This utility model utilizes the mounting groove in the middle of the frame in conjunction with the flip-over connecting component, allowing the anti-rollover structure to be flexibly flipped. When the toy car tends to roll over, the arc-shaped anti-rollover frame can promptly contact the ground to provide support. The limiting component, through the cooperation of the cover plate, limiting pressure block and limiting groove, can accurately limit the flip-over connecting component, ensuring that the damping pull-out telescopic rod can stably switch between horizontal and vertical states. This allows the anti-rollover structure to not affect the normal driving of the toy car when not in operation, and to effectively play its anti-rollover role when in operation. The elastic reset component, with the reset torsion spring and the damping pull-out telescopic rod working together, allows the anti-rollover structure to automatically reset after completing the anti-rollover function. The setting of the positioning groove avoids component interference, improves the smoothness of structural operation, greatly reduces the probability of the toy car rolling over, and ensures the play experience and the life of the toy.

[0011] 2. The flip-connecting assembly of this utility model adopts a combination of U-shaped seat, damping pin and connecting block to realize flexible rotational connection between the anti-tipping structure and the toy car body. It is convenient to adjust the angle according to the needs. The mounting seat and snap-fit ​​groove design of the elastic reset assembly, together with the manual bolt fixing of the arc-shaped anti-tipping frame, can flexibly adjust the height of the anti-tipping frame from the ground to adapt to different play scenarios and toy car status. The setting of multiple guide rollers improves the stability of the anti-tipping frame when in contact with the ground. The detachable and adjustable structural design of each component effectively enhances the maintenance convenience and functional adaptability of the anti-tipping structure, making the anti-tipping performance of the toy car more reliable and more flexible to use, meeting the diverse play needs of children, and improving the practicality and market competitiveness of the product.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] Please see Figures 1-4 This utility model provides a plastic toy car anti-tipping structure, including a plastic toy car body 100, two flip-connecting components 200, an elastic reset component 300, and an arc-shaped anti-tipping frame 400. The toy car body 100 has mounting slots 110 on both sides of the middle section of its frame. The two flip-connecting components 200 are correspondingly installed in the mounting slots 110. Each flip-connecting component 200 has a limiting component 210 at its top for limiting its flipping. The elastic reset component 300 is connected to the flip-connecting components 200 via a damping pull-out telescopic rod 310. The elastic reset component 300 includes a mounting base 320 installed at one end of the damping pull-out telescopic rod 310. The anti-tipping frame 400 is installed in a snap-fit ​​groove 321 in the mounting base 320, and the height of the anti-tipping frame 400 relative to the ground is adjustable.

[0020] Specifically, when children play with plastic toy cars, if they encounter situations such as sudden turns or bumpy roads, the toy car tends to tip over. The flip-connecting component 200 can rotate flexibly around its own connecting structure. In conjunction with the top limiting component 210, it can break through the initial limit when the toy car tilts, driving the elastic reset component 300 and the anti-tipping frame 400 to move. When the toy car tilts, the anti-tipping frame 400 contacts the ground before the wheels. Utilizing the support characteristics of the arc structure, it provides reverse support force to the toy car, preventing further tipping. Once the toy car returns to stability, the elastic reset component 300 drives all components to reset, and the anti-tipping frame 400 leaves the ground without affecting the normal driving of the toy car, achieving a continuous process of dynamic anti-tipping and reset.

[0021] In this embodiment: the flip connection assembly 200 includes a U-shaped seat 220 fixedly installed in the mounting groove 110. A connecting block 240 is rotatably installed inside the U-shaped seat 220 through a damping pin 230. One end of the connecting block 240 is fixedly connected to the damping pull-out telescopic rod 310.

[0022] Specifically, when a child is about to play with the plastic toy car, the damping pull-out telescopic rod 310 is manually operated to move the flip-connecting assembly 200 from a vertical storage state to a horizontal working state. The U-shaped seat 220 fixed in the mounting groove 110 serves as a support base. The connecting block 240 rotates within the U-shaped seat 220 via the damping pin 230. The damping force provided by the damping pin 230 makes the manual adjustment process smooth and controllable, avoiding structural collision damage caused by excessively fast adjustment. After adjusting to the horizontal state, the damping force of the damping pin 230 can keep the connecting block 240 in a stable position, ensuring that the elastic reset assembly 300 and the anti-tipping frame 400 are in an effective anti-tipping position.

[0023] When the toy car tends to tip over during play, the horizontal flipping connection component 200 can quickly transfer the tilting force to the elastic reset component 300 and the anti-tipping frame 400, triggering the anti-tipping action. After play, the connecting block 240 can be manually rotated in the opposite direction to drive the damping pull-out telescopic rod 310 back to the vertical state, reducing space occupation and not affecting the storage and normal storage of the toy car, realizing flexible switching between the anti-tipping structure working state and the storage state.

[0024] In this embodiment: the limiting component 210 includes a cover plate 211 that is hinged to one side of the mounting groove 110 by a hinge. The bottom of the cover plate 211 is fixedly connected to a limiting block 212 for limiting the damping pull-out telescopic rod 310 to a horizontal state and cooperating with the pressing connecting block 240 to limit it. The surface of the cover plate 211 is provided with a limiting groove 213 for locking and limiting the damping pull-out telescopic rod 310 to a vertical state.

[0025] Specifically, during the manual adjustment of the damping telescopic rod 310 to a horizontal working state, in the initial vertical state, the cover plate 211 covers the mounting groove 110, and the limiting block 212 presses down on the damping telescopic rod 310 to keep it vertically stable. When the damping telescopic rod 310 is manually rotated to a horizontal state, the cover plate 211 is lifted and flips around the hinge. In the horizontal state, the shape design of the limiting block 212 matches the damping telescopic rod 310 to limit its horizontal movement and prevent the connecting block 240 from rotating excessively during the anti-tipping process, which would cause the anti-tipping to fail.

[0026] When it is necessary to restore the vertical position, manually rotate the damping pull-out telescopic rod 310 upwards. The cover plate 211 falls back under the action of gravity, and the limiting groove 213 accurately engages the damping pull-out telescopic rod 310 in the vertical position, ensuring that it will not accidentally flip over when the toy car is driving normally. This achieves precise positioning and locking of the anti-tipping structure in different working states, ensuring safety and stability in use.

[0027] In this embodiment: the elastic reset assembly 300 includes a reset torsion spring 330 fitted to one end of the damping pull-out telescopic rod 310, and the reset torsion spring 330 and one end of the damping pull-out telescopic rod 310 are placed inside the mounting base 320, and one end of the reset torsion spring 330 is fixedly connected to the damping pull-out telescopic rod 310, and the other end of the reset torsion spring 330 is fixedly connected to the mounting base 320. The bottom of the mounting base 320 is also provided with a clearance groove 322 between the two snap-fit ​​grooves 321.

[0028] Specifically, when manually adjusting the length of the damping telescopic rod 310 to adapt to different anti-tipping requirements, and when it is necessary to increase the anti-tipping support range, the damping telescopic rod 310 is manually stretched. The return torsion spring 330 undergoes torsional deformation as the telescopic rod is stretched, storing elastic potential energy. After being stretched to the required length, the damping characteristics of the damping telescopic rod 310 itself keep the length fixed, and the elastic force of the return torsion spring 330 helps to maintain the stretched state.

[0029] When the toy car tipes over and triggers the anti-tipping frame 400 support, the reset torsion spring 330 deforms further to absorb impact energy and improve the anti-tipping effect. After playing, the damping pull-out rod 310 can be manually shortened, and the reset torsion spring 330 releases elastic potential energy to assist the telescopic rod in retracting, so that the structure returns to a compact state.

[0030] In this embodiment: the arc-shaped anti-tipping frame 400 includes two arc-shaped plates 410 respectively placed inside two snap-fit ​​slots 321. Multiple guide rollers 420 are rotatably installed between the two arc-shaped plates 410. The outer sides of the two arc-shaped plates 410 are abutted and fixed by manual bolts 430 that are threadedly connected to the mounting base 320.

[0031] Specifically, depending on the needs of different play scenarios, the height of the curved anti-tipping frame 400 can be manually adjusted. When encountering rough surfaces or requiring higher anti-tipping stability, the manual bolt 430 can be loosened to allow the curved plate 410 to slide and adjust within the locking groove 321. The curved plate 410 can be moved downwards to increase the contact distance between the anti-tipping frame 400 and the ground. The manual bolt 430 can be tightened to press against the outer side of the curved plate 410, fixing the position through friction. When the anti-tipping frame 400 contacts the ground, the rollers roll to reduce frictional resistance, allowing the toy car to maintain a certain degree of flexibility in the anti-tipping support state and avoiding movement jamming due to support.

[0032] If on a smooth surface or if a more compact structure is required, the operation can be reversed, and the height of the arc plate 410 can be adjusted upward to shorten the distance between the anti-tipping frame 400 and the ground. The rotation design of the guide roller 420 can also guide the anti-tipping frame 400 to smoothly detach from the ground when the toy car tilts and resets, assisting the elastic reset component 300 to complete the reset process, thus achieving the dual optimization of adjustable anti-tipping structure height and efficient anti-tipping function.
