[0002] Toy cars are miniature versions of real motor vehicles. Traditional toy cars have relatively simple structures, merely mimicking the appearance of motor vehicles, and are primarily for display with limited playability. Therefore, some toy cars that can actually drive have appeared on the market. However, the suspension mechanisms of these toy cars are either overly complex, making assembly extremely difficult and hindering the addition of other accessories, or overly simple, resulting in a loose overall structure with poor impact and shock resistance. Furthermore, existing suspension structures often use plastic components, which are prone to deformation and breakage, leading to a poor user experience. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, this utility model provides a toy car suspension structure, including a suspension device with a front axle and a rear axle connected to both ends of the suspension device; a fixing member connected to the suspension device; and a shock-absorbing device placed around the suspension device for shock absorption of the toy car.

[0004] The beneficial effects of this utility model are as follows: This utility model provides a toy car suspension structure, including a suspension device with a front axle and a rear axle connected to both ends of the suspension device; a fixing member connected to the suspension device; and a shock-absorbing device placed around the suspension device for shock absorption of the toy car. The suspension device is made of aluminum alloy, which improves durability and strength. The suspension device is curved, which increases the gap between the chassis and the ground, improving the toy car's ability to avoid obstacles. Attached Figure Description
