Description

Technical Field

[0001] The utility model relates to a front face structure for a vehicle, belonging to the technical field of mining dump trucks. Background Art

[0002] The front face of a mining dump truck generally refers to the covering parts at the front end of the vehicle. The front face of a traditional mining dump truck is generally divided into three parts: left, middle, and right, and they are fixed to the frame by bolts. In the subsequent maintenance process, if the components and facilities on the inside of the front face need to be repaired, the front face has to be disassembled and assembled repeatedly, which reduces work efficiency and easily leads to defects such as damage to the paint surface of the covering parts, deformation of the front face, and reduced reliability of the connecting parts. In addition, due to the limited manufacturing level of the split front face, it is often difficult to ensure that the gaps between the parts are uniform, which will also affect the appearance of the product. Furthermore, in order to ensure the structural rigidity of each part and the rooting of the installation connection points, most of the area of ​​the split front face is completely covered, and there are relatively few air vents, which is not convenient for the timely heat dissipation of the heating components inside the vehicle body. Therefore, it is necessary to design an integral, movable, and breathable front face. Summary of the invention

[0003] In view of the deficiencies in the prior art, the utility model provides a front face structure for a vehicle, which solves the problems of inconvenient disassembly and assembly of the front face and defects caused by repeated disassembly and assembly through the fixing method of lock hinges; solves the problems of uneven and inconsistent gaps after assembly of the front face by designing the entire front face of the vehicle as a whole; and solves the problem of difficulty in heat dissipation of heat-generating components inside the vehicle body by adopting a large-area mesh panel as the surface skin.
