The conical triangular frame 51 is arranged on the limiting support plate 2 at one end away from the outer guard plate 1, and the conical triangular frame 51 is adapted to the outer wall of the conical triangular buffer tube 3, that is, the inner walls of each side of the conical triangular frame 51 are respectively in contact with the outer walls of each side of the conical triangular buffer tube 3. The conical triangular buffer tube 3 is made of metal, such as copper, and the conical triangular buffer tube 3 adopts a thin-wall structure, so that the conical triangular buffer tube 3 has good elasticity.

[0032] See also Figure 1-Figure 5 When the head of the sightseeing car collides with an external object, the outer guard plate 1 is subjected to the collision impact, thereby causing the first U-shaped metal sheet 41 connected to the outer guard plate 1 to deform, prompting each second U-shaped metal sheet 42 and the first U-shaped metal sheet 41 connected to the limiting support plate 2 to deform, so as to alleviate the collision impact on the outer guard plate 1; at the same time, since the outer conical triangular buffer tube 3 is provided with a conical triangular frame 51, when the outer guard plate 1 is subjected to the impact, the conical triangular buffer tube 3 will squeeze the conical triangular frame 51, thereby causing each conical triangular buffer tube 3 to deform, and further The impact strength is further reduced; the conical triangular buffer tube 3 and the conical triangular frame 51 are both triangular tubular structures with a certain taper.
