[0023] See also Figure 1-6 , an embodiment provided by the utility model:

[0024] A chassis of a four-way shuttle vehicle: comprising a chassis inner frame 1, a connecting bottom plate 11 is fixedly connected to the surface of the chassis inner frame 1, a chassis outer frame 12 is fixedly connected to the surface of the connecting bottom plate 11, a part of a transmission mechanism is formed between the chassis inner frame 1 and the chassis outer frame 12, and a collision prevention mechanism is arranged on the surface of the chassis outer frame 12, and the collision prevention mechanism comprises a guide frame 2, the guide frame 2 is fixedly connected to the surface of the chassis outer frame 12, a reinforcing plate 21 is fixedly connected to the surface of the guide frame 2, a protective plate 22 is slidably connected to the surface of the guide frame 2, a telescopic damper 23 is fixedly connected to the surface of the chassis outer frame 12, and a spring 24 is fixedly connected to the surface of the chassis outer frame 12, and the collision prevention mechanism can reduce the probability of the protective plate 22 being dented by impact, thereby reducing the frequency of replacement of the protective plate 22 by the staff and avoiding the trouble of frequent replacement of the protective plate 22.

[0025] Furthermore, a reinforcement mechanism is provided on the surface of the chassis inner frame 1, and the reinforcement mechanism includes a first nut 3, the first nut 3 is fixedly connected to the surface of the chassis inner frame 1, a first hexagonal bolt 31 is threadedly connected to the surface of the first nut 3, a second nut 32 is fixedly connected to the surface of the chassis outer frame 12, a second hexagonal bolt 33 is fixedly connected to the surface of the second nut 32, and a reinforcement rod 34 is connected to the surface of the second hexagonal bolt 33 through a hole, and the reinforcement mechanism improves the connection strength between the chassis inner frame 1 and the chassis outer frame 12, thereby improving the overall structural strength of the four-way shuttle.

[0026] Furthermore, the reinforcing plate 21 is in the shape of a right-angled triangle, one right-angled side of the reinforcing plate 21 is fixedly connected to the guide frame 2, and the other right-angled side of the reinforcing plate 21 is fixedly connected to the chassis outer frame 12. The reinforcing plate 21 strengthens the stability of the guide frame 2 on the chassis outer frame 12, and the protective plate 22 slides on the surface of the chassis outer frame 12 through the guide frame 2. After being hit, the protective plate 22 will slide on the guide frame 2 toward the chassis outer frame 12.

[0027] Furthermore, the piston rod of the telescopic damper 23 is fixedly connected to the surface of the protective plate 22, the end of the spring 24 away from the chassis outer frame 12 is fixedly connected to the protective plate 22, the spring 24 is sleeved on the outer surface of the telescopic damper 23, and two groups of telescopic dampers 23 and springs 24 are arranged on the protective plate 22 and are symmetrically distributed on the protective plate 22.

[0028] Furthermore, the elastic force of the spring 24 acts on the protective plate 22. There are four groups of protective plates 22 distributed on the four sides of the chassis outer frame 12. The telescopic damper 23 and the spring 24 can cushion the protective plate 22 after the protective plate 22 is hit, thereby preventing the protective plate 22 from directly sinking and reducing the probability of the protective plate 22 sinking.

At this time, the protective plate 22 is buffered with the cooperation of the telescopic damper 23 and the spring 24 to prevent the protective plate 22 from directly sinking, thereby reducing the probability of the protective plate 22 being sunken, thereby reducing the frequency of replacement of the protective plate 22 by the staff and avoiding the trouble of frequent replacement of the protective plate 22.
