Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as Figure 1-5 As shown, a front bumper bottom guard structure of the present invention includes a bottom guard body 2, the bottom guard body 2 is installed between the front frame 5 and the front bumper 1, the front end of the bottom guard body 2 is connected to the front bumper The bar 1 is overlapped, the rear end is fixedly connected with the lower beam 5.1 of the front-end frame 5, and the bottom guard body 2 closes the gap between the front bumper 1 and the front-end frame 5, so as to improve the wind resistance of the vehicle and the heat dissipation performance of the cabin.

[0017] The bottom guard body 2 is provided with calf support beams 2.1 and horizontal and vertical grid ribs 2.2, and the horizontal and vertical grid ribs 2.2 are arranged in the overlapping area between the bottom guard body 2 and the front bumper 1,...

Abstract

The invention relates to a bottom guard plate structure of a front bumper. The structure comprises a bottom protection plate body, the bottom protection plate body is installed between a front end frame and the front bumper, the front end of the bottom protection plate body is in lap joint with the front bumper, the rear end of the bottom protection plate body is fixedly connected with a lower cross beam of the front end frame, and a gap between the front bumper and the front end frame is sealed to achieve the effect of improving the whole vehicle wind resistance and the cabin heat dissipationperformance; and a shank supporting cross beam and transverse and vertical grid ribs are arranged on the bottom protection plate body, the transverse and vertical grid ribs are arranged in the lap joint area of the bottom protection plate body and the front bumper, and the shank supporting cross beam is arranged at the rear portions of the transverse and vertical grid ribs. When a pedestrian collides, the transverse and vertical grid ribs play a role in preliminary buffering and energy absorption, and the shank supporting cross beam behind the transverse and vertical grid ribs plays a role inmain energy absorption and supporting. In pedestrian protection leg type collision, the integrated shank supporting cross beam absorbs collision energy, so that light weight is achieved, and impact energy on the lower portion of the shank of a pedestrian can be effectively absorbed.

Description

technical field [0001] The invention relates to the technical field of automobile pedestrian protection, in particular to a front bumper bottom guard plate structure. Background technique [0002] As consumers have higher and higher requirements for automobile quality and stricter requirements for fuel consumption regulations, the wind resistance of the vehicle is getting lower and lower, and the performance requirements for NVH and heat dissipation are also getting higher and higher. Moreover, as the world pays more and more attention to the safety of pedestrians, relevant laws and regulations are gradually promoted. Parts for pedestrian protection have also been added to the front of the vehicle. The bottom guard body between the traditional front bumper and the front-end frame is mainly used to close the bottom gap and improve the drag coefficient of the vehicle. At the same time, it also forms the intake channel of the radiator together with the spoiler at the rear of t...
