Description

Front wheel cover supporting structure

Technical Field

The invention relates to the improvement design of automobile parts, in particular to a front wheel cover supporting structure.

Background

The wading working condition of the whole vehicle: the wading problem of the vehicle is mainly to study the situation when the vehicle runs on a relatively deep water road surface at a relatively low speed, and in this case, the integrity and normal operation of a system of the vehicle OEM (Original Equipment Manufacturer) need to be ensured, for example, the tightness of a lower vehicle body of an electric car needs to be ensured, and the integrity of a high-voltage system of a battery pack and an electronic control system needs to be ensured. When the front part of the electric car and the lower bottom guard plate of the battery pack are designed, especially the water level height and the water flow incidence condition are considered, and once the sealability of the lower car body fails, the irreversible adverse effect on the power system of the electric car can be caused.

The vehicle wading working condition is a conventional working condition for evaluating the tightness of a vehicle body (electric car) and a lower vehicle body (chassis). At present, the electric vehicle is arranged with a lower vehicle body of a traditional fuel oil vehicle in a large different way, a cavity exists between a front wheel rear cover and a battery pack of the electric vehicle with a large long wheelbase, and based on the structural characteristics, under severe wading working conditions, the front wheel rear cover is easy to deform seriously, so that the tightness of the lower vehicle body is invalid. To cope with this, most of the main plants adopt foam filling spaces or change the lower vehicle body arrangement. The filling method has low cost but limited practical application effect, and the filler is limited by cost and materials and cannot cope with continuous impact of high-pressure water flow; design changes are not generally adopted due to overlong period and overhigh cost.

The current wading test working conditions adopted by the main stream host factory are shallow wading, the speeds of the wading test working conditions are 10km/h, 20km/h, 30km/h, 40km/h and 60km/h, and the water depths are 100mm, 200mm and 300mm. During the test, the flow and distribution conditions of water around key parts (front wheel cover mud guard and battery pack bottom guard) are recorded through a camera, and the deformation conditions of related parts are recorded. However, in the actual running scene of the vehicle or under the more severe water depth and vehicle speed, the common mud guard supporting structure is insufficient to cope with the huge deformation under the water pressure, so that the structure is collapsed, and the water inlet of the battery pack is invalid.

Therefore, two common problems exist in the existing vehicle wading working condition, and the two problems can not be solved well, so that the sealing performance of the lower vehicle body and the chassis is invalid when the lower vehicle body and the chassis are subjected to strong hydraulic pressure impact, the front wheel rear cover of the vehicle is seriously deformed, the battery pack is provided with a lower bottom guard plate, and further the battery pack is damaged, so that serious vehicle safety hazards are caused.

Problem one: is the energy absorption of the front wheel and the rear cover of the vehicle is insufficient. At present, when most vehicle types are subjected to wading experiments, parts of the front wheel rear cover capable of participating in energy absorption are fewer, so that high-pressure water can be caused to flow into the front wheel rear cover and the battery pack bottom guard plate after the vehicle is accelerated, the joint of the front wheel rear cover and the battery pack bottom guard plate is torn, the high-pressure water is caused to flow into the battery pack bottom guard plate, and the battery pack bottom guard plate is deformed.

And a second problem: the back supporting force of the front wheel rear cover of the electric automobile is insufficient in the design process, meanwhile, based on the difference between the electric automobile and the traditional fuel oil automobile, the back space of the structure is large, and deformation risks exist easily. Therefore, the reasonable design of the transverse support is beneficial to reducing the compression deformation of the front wheel and the rear cover and simultaneously reducing the tearing risk of the joint of the front wheel and the battery pack bottom guard plate under the wading working condition of the vehicle, and the tightness of the lower vehicle body and the battery pack is better ensured, so that the safety coefficient of the electric vehicle battery pack is improved.
