[0002] This application claims the benefit of Korean Patent Application No. 10-2019-0143691 filed on November 11, 2019, in the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to a vehicle under-cover mounting bracket and a vehicle under-cover assembly having the same. Background Art

[0004] A truck is a vehicle designed for transporting loads or goods. The truck frame has a pair of side rails that extend in the longitudinal direction of the truck and are spaced apart from each other in the width direction of the truck. Each side rail may be a C-shaped beam comprising a web having a predetermined height and a pair of flanges formed at the top and bottom ends of the web. Furthermore, the truck frame has at least one cross member connecting the side rails. The cross member has a length corresponding to the spacing between the side rails and a height corresponding to the height of the web of each side rail, such that the cross member fills the space between the webs of the side rails.

[0005] Power train components such as an engine and a transmission may be mounted on the truck frame, and a lower cover for protecting the lower sides of the power train components may be mounted to the truck frame. The lower cover can prevent stones flying from the ground from hitting the power train components such as the transmission and the engine while the vehicle is being driven, and protect the transmission and the engine from contamination by mud, calcium chloride used to remove snow, and the like.

[0006] The lower cowl can have a tunnel shape to cover portions of powertrain components, such as the transmission and engine, that are exposed beneath the truck frame. The lower cowl can be mounted to the truck frame using multiple mounting brackets. Several chassis components, such as a urea tank and emergency steering system, can be directly attached to the side rails of the truck frame adjacent to the lower cowl. At least one of the multiple mounting brackets can be directly coupled to the urea tank rather than the truck frame to avoid structural interference with chassis components other than the urea tank.

[0007] Since coupling the mounting bracket directly to the urea tank requires multiple components, this may increase manufacturing costs, and the installation process may be cumbersome, resulting in incorrect assembly or non-assembly of the lower cover.

[0008] Furthermore, when pipes such as brake pipes and fuel pipes are mounted on at least one side rail, it can be difficult to secure space for attaching a fixture (e.g., a bracket) for securing the pipes. This can prevent the pipes from being arranged straight along the longitudinal direction of the side rails. Consequently, the pipes may be bent at an angle on the side rails, resulting in reduced quality of pipe installation.

[0009] The above information described in the Background Art is provided only to help with understanding of the background of the inventive concept and may contain technical concepts that are not considered to belong to the prior art already known to one skilled in the art. Summary of the Invention

[0010] The present disclosure is intended to solve the problems encountered in the prior art while maintaining the advantages that can be achieved in the prior art intact.

[0017] The second bead may be continuously connected to the first bead.

[0018] The connecting portion may have a recess in which a strap for binding the tube to the connecting portion is tightened.

[0019] The lower cover side mounting portion may be parallel to the frame side mounting portion, and the connecting portion may be orthogonal to the lower cover side mounting portion and the frame side mounting portion.

[0020] According to another aspect of the present disclosure, a vehicle undercover assembly mounted between a first side rail and a second side rail of a truck frame may include: an undercover body having a bottom, a first side portion extending upward from a first edge of the bottom, and a second side portion extending upward from a second edge of the bottom; a first front mounting bracket connecting a front end of the first side portion to the first side rail; a first rear mounting bracket connecting a rear end of the first side portion to the first side rail; a second front mounting bracket connecting a front end of the second side portion to the second side rail, and a second rear mounting bracket connecting a rear end of the second side portion to the second side rail.

[0021] The first front mounting bracket may have a first frame-side connection point connected to the first web of the first side rail and a first undercover-side connection point connected to the front end of the first side portion. The first frame-side connection point and the first undercover-side connection point may be aligned in the width direction of the truck frame.

The connecting portion 73 may have a second flat portion 73a that contacts the second bottom flange 56 of the second side rail 32 and a second bead portion 73b that rises upward from the second flat portion 73a. Specifically, the second bead portion 73b of the connecting portion 73 may be continuously connected to the first bead portion 71b of the frame-side mounting portion 71, so that the rigidity of the second rear mounting bracket 44 can be improved.

[0072] refer to Figure 12 , the lower cover side mounting portion 72 may be parallel to the frame side mounting portion 71 , and the connecting portion 73 may be orthogonal to the frame side mounting portion 71 and the lower cover side mounting portion 72 .

[0073] To space the frame-side mounting portion 71 and the lower cover-side mounting portion 72 apart in the longitudinal direction of the second side rail 32, the connecting portion 73 may extend in the longitudinal direction of the second side rail 32. Specifically, the fourth frame-side joint 44a may be offset relative to the fourth lower cover-side joint 44b by a predetermined gap g2 in the longitudinal direction of the second side rail 32. For example, the fourth frame-side joint 44a may be offset from the fourth lower cover-side joint 44b toward the rear of the vehicle. That is, the frame-side mounting portion 71 may be closer to the rear of the vehicle than the lower cover-side mounting portion 72.

[0074] When the rear end 22 b of the second side portion 22 of the lower cover body 20 is coupled to the second side rail 32 of the truck frame 30 using the second rear mounting bracket 44, specifically, the frame side mounting portion 71 and the lower cover side mounting portion 72 are spaced apart from each other, so that interference of the bracket with other components used to mount powertrain components (transmission, engine, etc.) to the truck frame 30 can be minimized.

[0075] The second rear mounting bracket 44 may have at least one recess 74 in which a strap (not shown) for bundling brake pipes, fuel pipes, etc. is tightened.

[0076] refer to Figure 9 and Figure 10 , the second rear mounting bracket 44 may have a recess 74 formed in the rear end of the connecting portion 73. The recess 74 may be defined by a protrusion 74 protruding from the rear end of the connecting portion 73 toward the rear of the vehicle.

[0077] According to an exemplary embodiment of the present disclosure, when all ends 21a, 21b, 22a and 22b of the lower cover body 20 are mounted on the truck frame 30 using multiple mounting brackets 41, 42, 43 and 44, the mounting rigidity of the lower cover body 20 and the assembly capability of the lower cover body 20 can be significantly improved.
