本实用新型属于电动汽车技术领域，具体地说，本实用新型涉及一种四轮驱动电动越野车。The utility model belongs to the technical field of electric vehicles, in particular, the utility model relates to a four-wheel drive electric off-road vehicle.
背景技术Background technique
随着人们生活水平的提高，越野汽车在我们的生活中成为了必不可少的一部分。节假日出玩的人也越来越多，但是现在市面上的越野车基本上只能穿越相对复杂的路面，并不能做到真正意义上的越野。对于爬坡度来说，现在的越野车只能越过相对较小的坡度，对于坡度相对较大的山路，现在的越野车根本就不能轻松越过，驾驶员必须谨慎驾驶，如果稍有不注意就有可能翻车，对人造成很大的伤害。With the improvement of people's living standards, off-road vehicles have become an indispensable part in our lives. There are more and more people going out on holidays, but the off-road vehicles currently on the market can basically only cross relatively complicated roads, and cannot do off-road in the true sense. For climbing, current off-road vehicles can only cross relatively small slopes. For mountain roads with relatively large slopes, current off-road vehicles cannot easily cross them at all. Drivers must drive carefully. It may overturn and cause great injury to people.
对于路面的凹凸不平，现在的越野车也只能在一定的程度上减少车身的震动，使驾驶员处于紧张的环境，容易产生疲劳驾驶从而产生危险。对于路面上比较大的深坑来说，驾驶员只能绕道而行，稍微不注意就有可能掉入坑中，浪费很长时间从而摆脱大的坑道。而对于越野性能相对较好的越野汽车来说，其整个汽车车身的结构都比较复杂，生产技术难度增加从而使得生产成本增加。For the unevenness of the road surface, the current off-road vehicles can only reduce the vibration of the vehicle body to a certain extent, so that the driver is in a tense environment, which is prone to fatigue driving and thus danger. For relatively large deep pits on the road surface, the driver can only take a detour, and may fall into the pit without paying attention a little, wasting a long time to get rid of the big pit. For off-road vehicles with relatively good off-road performance, the structure of the entire vehicle body is more complicated, and the difficulty of production technology increases so that the production cost increases.
