The invention relates to a double-spring-bolt mechanism for an automobile ceiling screen, which comprises a pair of spring bolts which are respectively arranged on supports at the left end and the right end and can swing inwards and outwards, the middle parts of the spring bolts are hinged with the supports, the lower parts of the spring bolts are provided with tongues for locking the ceiling screen, and the upper parts of the spring bolts are also provided with push plates and connecting rods; the connecting rod is rotationally arranged between the pair of supports and is driven by a lock tongue actuator to rotate, eccentric wheels corresponding to the pair of lock tongues are arranged at the left end and the right end of the connecting rod respectively, the eccentric wheels at the two ends are in linkage with the connecting rod, push plates of the lock tongues correspond to the upper portions of the eccentric wheels, and the eccentric wheels at the two ends push the push plates corresponding to the lock tongues upwards; therefore, the tongue heads of the pair of lock tongues are driven to synchronously swing inwards to achieve locking, and the pair of lock tongues are driven by the elastic piece to reset to achieve unlocking. The pair of lock tongues can be simultaneously driven to rotate relatively to achieve locking or rotate oppositely to achieve unlocking, the cost is low, and the linkage performance is high.

    本发明涉及一种用在汽车吸顶屏上的双锁舌机构,包括:一对锁舌,分别装于左右两端的支座上、并可做内外摆动,锁舌中部与支座铰接、其下部具有用于锁住吸顶屏的舌头、且上部还具有推板,连杆,其转动装于一对支座之间、并由锁舌执行器驱动转动,在连杆的左右两端设有分别与一对锁舌对应的偏心轮,两端的偏心轮与连杆联动,所述锁舌的推板对应于偏心轮上方,由两端的偏心轮向上顶推对应锁舌的推板,从而驱使一对锁舌的舌头同步向内摆动实现闭锁,一对锁舌还由弹性件驱使复位实现开锁。可同时驱使一对锁舌做相对转动实现闭锁或相背转动实现开锁,成本低、联动性强。
