Description
技术领域technical field
本发明涉及汽车相关技术领域，特别是一种电动汽车前流水槽总成及电动汽车。The invention relates to the technical field related to automobiles, in particular to an electric vehicle front flow tank assembly and the electric vehicle.
背景技术Background technique
汽车前流水槽位于前挡风玻璃下部和机舱前围上部，顾名思义，前流水槽最简单的作用是将前风挡玻璃和通风盖板上留下来的水排掉,，避免水进入发动机舱内和驾驶室内，同时前流水槽还主要用于安装塑料通风盖板，前雨刮器等零部件The front water tank of the car is located at the lower part of the front windshield and the upper part of the front wall of the cabin. As the name suggests, the simplest function of the front water tank is to drain the water left on the front windshield and the ventilation cover, so as to prevent water from entering the engine compartment and In the cab, at the same time, the front water tank is mainly used to install plastic ventilation covers, front wipers and other components
近几年，消费者对汽车的质量、舒适性和安全性能要求越来越高，为了提高消费者满意度，同时为了应对国家的越来越严的法规，在车身研发过程中，整车强度刚度、NVH(噪音，振动、粗糙度三大指标的简称)和行人保护安全是衡量车身性能的三个重要指标，流水槽作为车身的一部分，其强度、刚度在车身结构设计中是首先必须保证的，且需满足CNCAP的碰撞要求，然后在满足刚、强度的基础上，根据行人保护和NHV的指标要求，进行适当合理的优化；In recent years, consumers have higher and higher requirements for the quality, comfort and safety performance of automobiles. In order to improve consumer satisfaction and to cope with the increasingly stringent regulations of the country, in the process of body research and development, the strength of the whole vehicle Rigidity, NVH (the abbreviation of the three major indicators of noise, vibration and roughness) and pedestrian protection are three important indicators to measure the performance of the vehicle body. It needs to meet the collision requirements of CNCAP, and then, on the basis of satisfying rigidity and strength, according to the requirements of pedestrian protection and NHV indicators, appropriate and reasonable optimization should be carried out;
在整车刚强度方面，现有技术的流水槽刚度不足。由于流水槽在车身前部起到承上启下的作用，在车身下部连接机舱左、右轮罩，在车身上部连接侧围的左、右A柱，因流水槽的这种特殊位置，在碰撞过程中，流水槽两侧(A柱接头)需要有足够的强度，将车头的碰撞能量有效、平衡地从左右两侧传递至车后。流水槽上部需提供支持面，用于粘接前风挡玻璃，因此，前流水槽也需要有足够的刚度，保证前风挡玻璃在车辆处于扭曲工况时不会出现变形、开裂等失效的情况。In terms of the rigidity of the whole vehicle, the rigidity of the water tank in the prior art is insufficient. Since the running water tank plays a role of linking up and down at the front of the car body, the lower part of the car body is connected to the left and right wheel covers of the cabin, and the upper part of the car body is connected to the left and right A-pillars of the side wall. Due to the special position of the running water tank, during the collision process , the two sides of the water tank (A-pillar joints) need to have sufficient strength to effectively and balancedly transmit the collision energy of the front of the car from the left and right sides to the rear of the car. The upper part of the water tank needs to provide a supporting surface for bonding the front windshield glass. Therefore, the front water tank also needs to have sufficient rigidity to ensure that the front windshield glass will not be deformed or cracked when the vehicle is in a twisted condition.
在保证足够的刚强度情况下，在NVH方面(解决NVH问题，一般从激励源——传递路径——响应这三部分)下手，如果激励源(主要是风噪、路面对轮胎的激励、电机运作产生的振动等)产生的振动与车身结构的频率比较接近，就容易产生共振，这会严重降低乘客和驾驶员的舒适度，因激励源无法控制，只有在传递路径上优化，因此，需优化相关的车身结构，以尽量避开激励源的频率。In the case of ensuring sufficient rigidity, in terms of NVH (to solve the NVH problem, generally start from the three parts of excitation source-transmission path-response), if the excitation source (mainly wind noise, excitation of the road to the tire, The vibration generated by motor operation, etc.) is relatively close to the frequency of the body structure, and it is easy to generate resonance, which will seriously reduce the comfort of passengers and drivers. Because the excitation source cannot be controlled, it can only be optimized on the transmission path. Therefore, The relevant body structure needs to be optimized to avoid the frequency of the excitation source as much as possible.
然而，现有技术的前流水槽总成主要是针对燃油车的。电动汽车和燃油车的动力输出不同，燃油车是发动机输出动力，电动汽车是电机输出动力，发动机和电机的机械性能和扭矩输出特性截然不同，发动机噪音、振动主要集中在低频段，而电动机的噪音、振动主要集中在高频段，因此，燃油车和电动汽车在传递路径上的车身结构会有些差异，这也体现在电动汽车的车身前流水槽处结构会与燃油车有些差异。However, the front flow tank assembly of the prior art is mainly aimed at fuel vehicles. The power output of electric vehicles and fuel vehicles is different. Fuel vehicles output power from the engine, while electric vehicles output power from the motor. The mechanical properties and torque output characteristics of the engine and the motor are completely different. The noise and vibration of the engine are mainly concentrated in the low frequency band, while the motor's Noise and vibration are mainly concentrated in the high-frequency band. Therefore, there will be some differences in the body structure of fuel vehicles and electric vehicles on the transmission path, which is also reflected in the structure of the front water tank of electric vehicles and fuel vehicles.
同时，现有技术的前流水槽总成在行人保护方面不足，当车辆与行人发生碰撞时，前流水槽处挡风玻璃通常是行人头部最容易接触的区域。现有技术的前流水槽总成，当头部撞击到该区域时，流水槽没有足够的自由空间来缓冲碰撞能量，这就会给行人致命的伤害，流水槽区域一般是CNCAP中行人保护安全扣分的严重区域。At the same time, the front gutter assembly of the prior art is insufficient in terms of pedestrian protection. When a vehicle collides with a pedestrian, the windshield at the front gutter is usually the area where the pedestrian's head is most likely to contact. In the prior art of the front water tank assembly, when the head hits this area, the water tank does not have enough free space to buffer the collision energy, which will cause fatal injuries to pedestrians. The water tank area is generally used for pedestrian protection in CNCAP. Severe areas of deduction.
