Description

Technical Field

[0001] This utility model relates to the field of automotive parts, specifically a front bumper lower grille structure. Background Technology

[0002] Traditional gasoline-powered vehicles, whether naturally aspirated or turbocharged, require air intake for their engines. The engine is typically located at the front of the vehicle, and therefore, a grille is usually installed to provide an air intake source and cooling channel, ensuring sufficient air enters the vehicle. New energy vehicles, as proposed in current technology, have abandoned internal combustion engines and therefore employ built-in cooling systems for heat dissipation. However, the installation of these cooling systems consumes electrical energy, thus affecting the vehicle's range. In today's environment where charging stations are scarce, this severely limits the usability of new energy vehicles. Therefore, how to rationally apply a lower grille to new energy vehicles to reduce the energy consumption of the cooling system has become an urgent problem to be solved.

[0003] To address the aforementioned issues, a search revealed that CN114290891A discloses a lower grille structure for an automobile bumper. The document describes this structure as including a fixed bracket, an air intake grille, and an adjusting bracket. The fixed bracket is located on the outer side of the air intake grille and is fixedly connected to it. The adjusting bracket cooperates with the air intake grille, and is located on the inner side of the air intake grille and cooperates with it.

[0004] Although the above-mentioned device can adjust the air intake of the lower grille, as is well known, the lower grille mainly consists of the grille and the outer frame, and is a one-piece molded structure. However, in actual use, once a part of the grille or the outer frame is damaged, since it is a one-piece molded structure, it is usually impossible to replace the damaged part separately. The whole thing usually needs to be replaced, which increases maintenance costs and time costs. Utility Model Content

[0005] The purpose of this utility model is to provide a front bumper lower grille structure to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, a front bumper lower grille structure is provided, including a grille frame. Multiple sets of mounting brackets are fixedly disposed at the bottom of the grille frame, and the grille frame is secured to the front bumper via these brackets. A positioning groove is provided inside the grille frame, and a grille plate is positioned and installed inside the positioning groove. Multiple sets of ventilation holes are evenly distributed on the grille plate. An assembly block is fixedly disposed at the bottom of the grille plate, and the surface of the grille plate is covered with an insect-repellent mesh, on which multiple sets of mesh holes are evenly distributed.

[0007] Preferably, the outer frame of the grille includes a positioning groove, assembly holes and a mounting base. The positioning groove has an "L" shaped cross-section and multiple sets of assembly holes are evenly provided on the positioning groove.

[0008] Preferably, the grating includes docking holes, ventilation holes, insect-proof lint mesh, mesh holes, stabilizing base, docking blocks, and assembly blocks, with multiple sets of assembly blocks evenly distributed on the bottom of the grating.

[0009] Preferably, multiple sets of assembly blocks are arranged opposite to multiple sets of assembly holes, the size of the assembly holes is adapted to the size of the assembly blocks, the assembly blocks are inserted into the interior of the assembly holes, and the grid frame and the grid plate are spliced ​​and installed with the assembly blocks through multiple sets of assembly holes.

[0010] Preferably, the grating plate has multiple sets of ventilation holes evenly distributed, the ventilation holes are arranged in regular hexagons, the grating plate has docking holes on both sides of its surface, and the bottom sides of the insect-proof mesh on the surface of the grating plate are fixedly provided with stabilizing seats and docking blocks.

[0011] Preferably, the size of the mating block is adapted to the size of the mating hole, the size of the stabilizing seat is adapted to the size of the ventilation hole, the stabilizing seat is inserted into the interior of the ventilation hole, and the mating block is inserted into the interior of the mating hole.

[0012] Preferably, the insect-proof mesh covers the surface of the grid plate and is positioned and installed by multiple sets of stabilizing seats, connecting blocks, connecting holes, and ventilation holes, and multiple sets of mesh holes are evenly opened on the insect-proof mesh.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model combines a grille panel and a grille frame to form a lower grille assembly for the front bumper. Compared with a one-piece molded structure, when a component of the combined lower grille assembly is damaged, only the damaged grille panel or grille frame needs to be replaced, instead of replacing the entire assembly, which greatly reduces maintenance costs and time costs. For car enthusiasts or professional modifiers, this combined structure facilitates the individual upgrading or modification of the grille panel and grille frame, such as replacing the grille panel with different styles, materials, and shapes to enhance the personalization of the vehicle's appearance.

[0015] 2. To prevent poplar catkins and mosquitoes from entering the vehicle body during high-speed driving, this utility model uses an insect-proof netting covering the surface of the grille plate and is positioned and installed through multiple sets of stabilizing seats, connecting blocks, connecting holes, and ventilation holes; the insect-proof netting can block mosquitoes or poplar catkins during driving.
