Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Korean Patent Application No. 10-2019-0143691, filed in the Korean Intellectual Property Office on Nov. 11, 2019, which application is hereby incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a vehicle undercover mounting bracket and a vehicle undercover assembly having the same.

BACKGROUND

A truck is a vehicle designed for transporting loads or goods. A truck frame has a pair of side rails extending in a longitudinal direction of the truck, and being spaced apart from each other in a width direction of the truck. Each side rail may be a C-shaped beam including a web having a predetermined height, and a pair of flanges formed on the top and bottom ends of the web. In addition, the truck frame has at least one crossmember connecting the side rails. The crossmember has a length corresponding to the spacing between the side rails and a height corresponding to that of the web of each side rail so that the crossmember may fill an empty space between the webs of the side rails.

Powertrain components such as an engine and a transmission may be mounted on the truck frame, and an undercover for protecting the underside of the powertrain components may be mounted to the truck frame. While the vehicle is driving, the undercover may prevent stones flying from the ground from hitting the powertrain components such as the transmission and the engine, and protect the transmission and the engine from being contaminated by mud, calcium chloride for snow removal, etc.

The undercover may have a tunnel shape so as to cover portions of the powertrain components, such as the transmission and the engine, which are exposed below the truck frame. The undercover may be mounted to the truck frame using a plurality of mounting brackets. A plurality of chassis components, such as a urea tank and an emergency steering system, may be directly attached to the side rails of the truck frame adjacent to the undercover. At least one mounting bracket among the plurality of mounting brackets may be directly coupled to the urea tank, not being directly coupled to the truck frame, so as to avoid structural interferences with the chassis components other than the urea tank.

As the mounting bracket directly coupled to the urea tank requires a number of members, the manufacturing cost thereof may be increased, and an assembly process may be cumbersome, resulting in mis-assembly or non-assembly of the undercover.

In addition, when tubes such as a brake tube and a fuel tube are mounted on at least one side rail, it is difficult to secure a space to which a fixing means (for example, brackets) for fixing the tubes is attached, so that the tubes may not be straightly arranged along a longitudinal direction of the side rail. As a result, the tubes may be bent at a certain angle on the side rail, thereby degrading the mounting quality of the tubes.

The above information described in this background section is provided to assist in understanding the background of the inventive concept, and may include any technical concept which is not considered as the prior art that is already known to those skilled in the art.
