Problems solved by technology

[0007] In order to overcome the problem that the energy-absorbing characteristics of the middle part of the hatch cover in the prior art cannot effectively support the pedestrian’s head impact, which will cause the first peak value of the head acceleration to be too low and the second peak value to be too high, which will cause high head injuries. The invention provides an engine compartment cover structure and a vehicle

Embodiment Construction

[0061] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0062] Front herein refers to the orientation of the vehicle when it is moving forward.

[0063] like Figure 1-Figure 10 As shown, the engine compartment cover structure in this example includes: an outer panel 100 arranged above the front of the vehicle, and an inner panel 200 disposed on the lower surface side of the outer panel 100, and the inner panel 200 includes: a circumferential sealing surface 20 , connecting surface 30 and supporting surface 40 .

[0064] The circumferential sealing surface 20 is arranged around the lower surface of the outer panel 100 to jo...

Abstract

The present invention provides an engine compartment cover structure and a vehicle. The engine compartment cover structure includes: an outer panel arranged above the front part of the vehicle, and an inner panel arranged on the lower surface side of the outer panel. The inner panel Including: circumferential sealing surface, connecting surface and supporting surface. The engine hatch structure disclosed by the present invention can effectively absorb impact energy when the head hits the area around the hatch cover because of the relatively gentle slope of the connecting surface supported by the outer panel around the inner panel, and reduce the risk of head injury; the middle structure of the inner panel It is tightly attached to the outer plate, which can effectively absorb the impact energy while forming an effective support for the central area of ​​the hatch cover, and reduce the risk of head injury when the head impacts the central area of ​​the hatch cover.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an engine compartment cover structure and a vehicle. Background technique [0002] As the proportion of pedestrian casualties caused by collisions between pedestrians and vehicles in the number of traffic accident deaths is increasing year by year, countries around the world have successively formulated regulations or standards to improve the ability to protect automobiles and pedestrians. The European Union and Japan have enforced pedestrian protection standards , China released the recommended national standard GB / T 24550-2009 in 2009. The New Car Assessment Program (NCAP) puts forward higher requirements for pedestrian protection. In 2002, Euro-NCAP and A-NCAP were the first to include pedestrian protection in the evaluation program. The US NCAP added pedestrian protection evaluation in 2016. China will include pedestrian protection in 2018. Pedestrian protection is...
