The invention relates to the technical field of vehicle engineering, and discloses a vehicle empennage system and an empennage lifting mechanism, the vehicle empennage system comprises a top support, a bottom support, a first connecting rod, a second connecting rod, a first driving rod and a second driving rod, the bottom support, the first connecting rod, the top support and the second connecting rod form a four-bar mechanism; the first driving rod and the second driving rod are sequentially connected end to end, and when the top support is in a completely-lifted or completely-closed state, the first driving rod drives the second driving rod to rotate beyond a dead point. When the first driving rod rotates, the second driving rod drives the first connecting rod and the second connecting rod to rotate, so that the top support and the spoiler are driven to move according to a set movement track, and the first driving rod rotates forwards and backwards to drive the spoiler to ascend or descend. Due to the fact that the first driving rod drives the second driving rod to rotate to exceed the dead point, mechanical self-locking is formed between the first driving rod and the second driving rod, and except the first driving rod is rotated, external force cannot be applied to lift or close the streaming plate from other structures.
本发明涉及车辆工程技术领域,公开了一种车辆尾翼系统及尾翼升降机构,包括顶部支架、底部支架、第一连杆、第二连杆、第一驱动杆和第二驱动杆,底部支架、第一连杆、顶部支架与第二连杆形成四连杆机构;第一驱动杆与第二驱动杆首尾顺次连接,顶部支架位于完全升起或者完全关闭状态时第一驱动杆均带动第二驱动杆转动超过死点。第一驱动杆转动时通过第二驱动杆带动第一连杆、第二连杆转动,从而带动顶部支架以及扰流板按照既定运动轨迹进行运动,第一驱动杆正反转带动扰流板举升或者下降;由于第一驱动杆带动第二驱动杆转动超过死点,第一驱动杆和第二驱动杆之间形成机械自锁,除了转动第一驱动杆外无法从其他结构上施加外力抬升或者关闭绕流板。
