Embodiment Construction

[0045] In a traffic accident, when a vehicle collides with a pedestrian, the lower leg is vulnerable to fractures or even more serious injuries. Especially when the vehicle collides with children, the strengthening of the leg protection also protects the children and reduces children's penetration under the car Causes secondary damage from crushing. Therefore, the pedestrian leg protection structure has attracted the attention of major automobile manufacturers, so the improvement of pedestrian protection will be considered in the development of new products.

[0046] The inventor has conceived two schemes for the structure of the vehicle's front protection system. The first one is to arrange the hard objects that are easy to cause damage, such as the vehicle's front protection beam, hair cover lock, and front protection skin bracket, at a position relatively behind the front of the vehicle. , and increase the structural size of the front energy-absorbing foam, energy-absorbing...

Abstract

The invention provides a protection structure for vehicles and a design method thereof and relates to the field of vehicle components. The protection structure is located at the front end of the vehicle and is used to protect the tibias and knees of a pedestrian's calf in the event of a collision between the vehicle and the pedestrian; the protection structure comprises a support body whose surface is provided with multiple first reinforcing ribs; a plurality of the first reinforcing ribs are configured to be arranged from one end of the support body along the length direction of the surface of the bracket body to the other end of the support body; adjacent two first reinforcing ribs are arranged crosswise so that the support body does not generate a local bending moment when the collisionoccurs, thereby protecting the calf shank of the pedestrian; the surface is the largest surface area of the support body. The invention solves the dangerous problems of fracture of lower tibia and knee of calf caused by collision between vehicle and pedestrian due to unreasonable protection structures in the prior art.

Description

technical field [0001] The invention relates to the field of vehicle components, in particular to a protective structure for vehicles and a design method thereof. Background technique [0002] With the rapid increase of vehicle ownership, accidents such as car accidents occur frequently. Due to the complex traffic situation in our country, there are often accidents where motor vehicles collide with non-motor vehicles and pedestrians. In such accidents, non-motor vehicle drivers and pedestrians are vulnerable groups, and their heads are hit by vehicles to cause death and serious injuries. Although injuries such as fractures of the femur and calf and tibia are not life-threatening, such accidents occur frequently and lead to many disabilities, which are also worthy of attention. EuroNCAP, the European new car evaluation organization, incorporated vehicle pedestrian protection performance into the evaluation system many years ago. Since 2010, my country has also promulgated th...
