In addition, the inner edge of the horizontal extension 32 may be flush with the edge of the bottom of the front bumper 1, and may also serve as a bumper and a garnish.
As shown in fig. 5, in order to combine the bottom guide plate 3 and the side guide plate 2 more reliably and reduce the overall height of the lower guide plate assembly, a limiting groove 33 is formed on the surface of the bottom guide plate 3 away from the ground, one end of the side guide plate 2 close to the ground is embedded in the limiting groove 33, and the end surface of the side guide plate 2 away from the ground is flush with the surface of the bottom guide plate 3 away from the ground. The limiting groove 33 is attached to the surface of the side guide plate 2, and the bottom guide plate 3 and the side guide plate 2 are convenient to position and assemble.
As shown in fig. 1, the side baffles 2 and bottom baffles 3 of the present invention are preferably arcuate. The structure has certain elasticity, can be more attached to the outline of a vehicle body, and can also play a certain protection function for the front bumper 1.
As shown in fig. 5 and 6, the side surface of the second body 31 is inclined with respect to the end of the second body 31 away from the ground. This configuration facilitates the introduction of a portion of the air between the bottom baffle 3 and the side baffle 2.
The invention also comprises an arc baffle 4, the arc baffle 4 is fixedly connected with the bottom guide plate 3, and the side surface of the arc baffle 4 is attached to the side surface of the bottom guide plate 3 and is positioned on the same curved surface. The end face of the arc-shaped baffle 4 is flush with the end face of the second body 31. The surface shapes of the second body 31 and the bottom guide plate 3 can be further optimized by the arc-shaped baffle plate 4, so that the air flow is facilitated, and the wind resistance of the travelling crane is further reduced.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
