Description

Technical Field

[0001] The utility model belongs to the technical field of automobile front bumpers, and particularly relates to an energy-absorbing foam device for supporting a front bumper, a front bumper and an automobile. Background Art

[0002] With the improvement of automobile technology level, the luxury degree of automobiles is getting higher and higher. Various electronic devices are added to the front face of automobiles, such as daytime running lights, through lights, AGS grilles, millimeter-wave radars, etc., resulting in heavier parts supported by the front bumper and a great risk of sinking. Even without installing additional devices, with the long-term use of the vehicle, due to vibrations and impacts during daily driving, the fixing parts of the front bumper will gradually become loose, resulting in the sinking of the bumper, causing appearance problems and increased wind resistance caused by the sinking of the front bumper. Moreover, the sinking of the front bumper will affect the performance of the vehicle's steering and suspension systems, and even further lead to detachment problems, affecting the safe driving of the vehicle. The existing front bumper system has no effective load-bearing structure and is difficult to carry the newly added electronic devices.

[0003] The Chinese patent publication number is CN116373772A, and the name of the patent application is a vehicle front-end energy-absorbing module, a vehicle frame and a vehicle. The energy-absorbing module includes: a foam main body extending along its longitudinal direction; a plurality of front vertical ribs arranged at intervals along the longitudinal direction of the foam main body, and adjacent two of the front vertical ribs are connected by a front horizontal rib, and the front horizontal rib is also connected to the foam main body, so that adjacent two of the front vertical ribs and the corresponding front horizontal rib and the foam main body enclose a front groove; a limiting column for inserting into a front anti-collision beam is arranged behind the foam main body. By arranging a plurality of front vertical ribs and front horizontal ribs on the foam main body, the rigidity of the energy-absorbing module can be improved, and the formed front groove is beneficial to improving the energy-absorbing effect. At the same time, by arranging a limiting column behind the foam main body, the front anti-collision beam can be inserted to install and fix the vehicle front-end energy-absorbing module. This patent application can improve the energy-absorbing effect of the energy-absorbing foam, but cannot solve the problem of supporting the front bumper. Summary of the Utility Model
