Background
the automobile front water flowing groove is positioned at the lower part of the front windshield and the upper part of the front wall of the engine room, and as the name suggests, the front water flowing groove has the simplest function of draining water left on the front windshield and the ventilation cover plate to prevent the water from entering the engine room and the cab, and is mainly used for installing parts such as a plastic ventilation cover plate, a front windscreen wiper and the like
In recent years, the requirements of consumers on the quality, comfort and safety performance of automobiles are higher and higher, in order to improve the satisfaction degree of the consumers and simultaneously meet the stricter regulations of the country, in the research and development process of an automobile body, the strength and rigidity of the whole automobile, NVH (noise, vibration and roughness) and the pedestrian protection safety are three important indexes for measuring the performance of the automobile body, a water flowing groove is used as one part of the automobile body, the strength and the rigidity of the water flowing groove are firstly required to be ensured in the structural design of the automobile body and are required to meet the collision requirement of CNCAP, and then proper and reasonable optimization is carried out according to the index requirements of pedestrian protection and NHV on the basis of meeting the rigidity and the strength;
In the aspect of the rigidity and the strength of the whole vehicle, the rigidity of the water flowing groove in the prior art is insufficient. Because the launder plays the effect of holding up and down in the automobile body front portion, connect the left, right wheel casing of cabin in the automobile body lower part, connect the left, right A post of side wall in the automobile body upper portion, because of this kind of special position of launder, in the collision process, the launder both sides (A post joint) need have sufficient intensity, with the collision energy of locomotive effectively, the balanced transmission to the back of car from the left and right sides. The upper part of the water flowing groove needs to provide a supporting surface for bonding the front windshield glass, so that the front water flowing groove also needs to have enough rigidity to ensure that the front windshield glass cannot deform, crack and other failures when a vehicle is in a twisting working condition.
Under the condition of ensuring enough rigidity, in terms of NVH (solving NVH problems, generally from three parts of an excitation source-a transmission path-responding), if vibration generated by the excitation source (mainly wind noise, excitation of a road surface to a tire, vibration generated by motor operation and the like) is relatively close to the frequency of a vehicle body structure, resonance is easy to generate, the comfort of passengers and a driver is seriously reduced, and the excitation source cannot be controlled and is only optimized on the transmission path, so that the related vehicle body structure needs to be optimized to avoid the frequency of the excitation source as far as possible.
However, prior art front flume assemblies are primarily directed to fuel vehicles. The power output of an electric automobile is different from that of a fuel automobile, the fuel automobile is engine output power, the electric automobile is motor output power, the mechanical performance and the torque output characteristic of the engine and the motor are completely different, the noise and the vibration of the engine are mainly concentrated in a low-frequency section, and the noise and the vibration of the motor are mainly concentrated in a high-frequency section, so that the body structures of the fuel automobile and the electric automobile on a transmission path are slightly different, and the difference between the structure of the body front water flowing groove of the electric automobile and the structure of the body front water flowing groove of the fuel automobile is reflected.
Meanwhile, the front water channel assembly of the prior art is insufficient in pedestrian protection, and when a vehicle collides with a pedestrian, the windshield at the front water channel is usually the most easily contacted area by the head of the pedestrian. In the prior art front gutter channel assembly, when the head part impacts the area, the gutter channel does not have enough free space to buffer the collision energy, so that the pedestrian can be fatally injured, and the gutter channel area is generally a serious area for protecting and safety deducting the pedestrian in the CNCAP.
