A car roof ventilation system comprises a ventilation plate (11) which can be driven under the condition that a servo motor (14) outputs torque, is rigidly fixed to an executing mechanism (13) and a rotating hinge (16) and can tilt relative to a bottom plate (17), and the car roof ventilation system is technically characterized in that a gear (134) is arranged at the output end of the servo motor (14); a plurality of ventilation openings (171) are formed in the bottom plate (17) in the transverse direction at intervals. The executing mechanism (13) comprises a ventilation plate support (135) used for fixing the ventilation plate (11), a fixing support (131) used for fixing the bottom plate (17), a U-shaped rotating arm (132) driven by the servo motor (14) to rotate around the fixing support (131), and a supporting arm (133) arranged between the U-shaped rotating arm (132) and the ventilation plate support (135) in a matched mode through double pivotal shafts. The air conditioner has the advantages of being simple and compact in structure, high in ventilation efficiency and smaller in air noise.
一种车顶通风系统,包括可在伺服电机(14)输出扭矩的条件下驱动的刚性固定在执行机构(13)和旋转铰链(16)上的可相对于底板(17)起翘的通风板(11),其技术要点是:伺服电机(14)的输出端设有齿轮(134);底板(17)上沿横向间隔设有若干通风口(171);执行机构(13)包括用于固定通风板(11)的通风板支架(135)、用于固定底板(17)的固定支架(131)、由伺服电机(14)驱动的绕固定支架(131)旋转的U形转臂(132)、以双枢转轴配合在U形转臂(132)和通风板支架(135)之间的支撑臂(133)。其具有结构简单紧凑、通风换气效率高、风噪更小的优点。
