Description

Technical Field

[0001] This utility model relates to the field of automotive parts decoration technology, specifically to a front bumper daytime running light decorative panel. Background Technology

[0002] The front bumper and daytime running lights are important structural components of a car. In the event of a collision, the front bumper absorbs and disperses the impact force, reducing injury to the vehicle's structure and occupants. Daytime running lights enhance the vehicle's visibility during the day, making it easier for other road users to notice the vehicle. During vehicle assembly, the daytime running lights and front bumper are combined and installed through a front trim panel. A well-designed trim panel and the installation position of the daytime running lights can help optimize the aerodynamic performance of the front bumper, reduce air resistance and turbulence, and improve the vehicle's fuel economy and driving stability.

[0003] The heat dissipation design of the front trim panel of a car is a key aspect of balancing performance and cost. Currently, the mainstream heat dissipation structure guides airflow through strip or mesh openings, effectively reducing the temperature in areas such as the engine compartment. However, as the vehicle operates at high speeds, the heat dissipation structure may be damaged by external impacts, requiring complete replacement and incurring high repair costs. In addition, the heat generated by the daytime running lights during operation, combined with the heat source in the engine compartment, causes the trim panel near the daytime running lights to have a significantly higher temperature than other parts. Targeted heat dissipation enhancements are needed for the high-temperature area near the daytime running lights, but existing trim panels lack specific heat dissipation features for the daytime running lights area.

[0029] The both sides of the plate body 1 are provided with day running light areas 4, and the partition plates 302 in the heat dissipation grilles 3 near the day running light areas 4 are obliquely installed, and the partition plates 302 are obliquely installed towards the positions of the day running light areas 4.

[0030] The heat dissipation grilles 3 in the middle positions of the cutting grooves 2 are provided with a plurality of cross panels 5, and the cross panels 5 are obliquely upwards.

[0031] The side surfaces of the partition plates 302 in the remaining heat dissipation grilles 3 are formed with obliquely upwards groove surfaces.

[0032] In the embodiment, the top and bottom of each outer support plate 301 are provided with threaded holes, the outer support plates 301 are embedded into the plate body 1 and are attached to the edges of the cutting grooves 2, and then the outer support plates 301 are fixed by bolts in sequence to realize precise embedding and to realize close attachment between the outer support plates 301 and the plate body 1, so as to ensure the structural stability, the outer support plates 301 are distributed side by side to construct a modular installation platform, and the single module can be quickly disassembled during later maintenance to reduce the maintenance cost.

[0033] The partition plates 302 in the heat dissipation grilles 3 at both ends of the cutting grooves 2 and near the day running light areas 4 are respectively obliquely towards the day running light areas 4 on both sides, and the bidirectional flow guide groove design is adopted, when the automobile is running, the air is concentrated and the flow rate is increased through the oblique groove surface, the air flow flows towards the day running light areas 4, and the overall heat dissipation efficiency of the plate body 1 near the day running light areas 4 is improved.

[0034] Further, as shown in Figure 2 and Figure 3 , the partition plates 302 in the heat dissipation grilles 3 near the day running light areas 4 are divided into inner side sub-plates 303 and outer side sub-plates 304 according to the installation positions, the inner side sub-plates 303 are obliquely installed towards the installation positions of the day running light areas 4, and the included angle between the inner side sub-plates 303 and the outer side sub-plates 304 is greater than 90°.

[0035] In the embodiment, the outer side sub-plates 304 are arranged outside the plate body 1 to increase the contact area with the air, a bending angle greater than ninety degrees is formed between the inner side sub-plates 303 and the outer side sub-plates 304, the air flow is obliquely guided towards the day running light areas 4 without affecting the passage area of the air flow, the air flows more smoothly through the heat dissipation grilles 3, the air flow is directionally and concentratedly transported to the day running light areas 4, the air is directionally blown, the heat is concentratedly dissipated, and at the same time, a physical barrier is formed to avoid the direct intrusion of external sundries.
