[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1 , Figure 2 , Figure 3 As shown, this safe and stable sand protection structure for beach buggies includes a vehicle body 1 and a body 2 located at the bottom of the vehicle body 1. Wheels 3 for moving the vehicle body 1 are located at both ends of the body 2. Each wheel 3 includes a hub 4 and a tire body 5. A fixed seat 6 is located at the center of the hub 4, and a through hole 7 is opened at the center of the fixed seat 6. A bearing 8 is installed inside the fixed seat 6. The wheels 3 and the body 2 are connected by a suspension assembly 9. A swing arm shaft 10 is provided on the suspension assembly 9, and a connecting rod 11 is provided on the swing arm shaft 10. The connecting rod 11 is installed in the through hole 7 of the wheel 3 and passes through the bearing 8. One end of the connecting rod 11 is connected to the swing arm shaft 10. Through the transmission action of the connecting rod 11, the up-and-down movement of the wheel 3 can be converted into elastic deformation of the suspension system, thereby buffering and absorbing impact forces. A groove 12 is formed between the connecting rod 11 and the fixed seat 6. A sand protection component 13 is installed in the groove 12 and is fitted onto the connecting rod 11.
