The invention discloses a transmission structure of an electronic steering column lock of an automobile, the steering column lock is provided with a lock tongue for locking, one side of the lock tongue is provided with an extending boss, the boss is embedded into a spiral groove of a transmission column, the bottom of the transmission column is provided with a circle of transmission teeth, the transmission teeth are meshed with a worm, and the worm is provided with a transmission shaft. The worm is fixed to an output shaft of a motor used for controlling the locking state of the steering column. According to the transmission structure applied to the automobile electronic steering column lock, a primary transmission mechanism is adopted, the worm and the bevel gear are subjected to displacement parameter design, and the worm is made of brass instead of engineering plastic, so that the problems of the strength of the worm and the service life of ESCL transmission are solved, the installation space of the ESCL is greatly improved, the universality is also improved, and the service life of the ESCL is prolonged. And along with reduction of the number of stages of the internal transmission mechanism, the possibility of generating abnormal sound is reduced, and the manufacturability and the economical efficiency are also greatly improved.
本发明揭示了一种汽车电子转向柱锁的传动结构,转向柱锁具有用于锁止的锁舌,所述锁舌一侧设有伸出的凸台,所述凸台嵌入到传动柱的螺旋槽内,所述传动柱的底部设有一圈传动齿,所述传动齿与蜗杆啮合,所述蜗杆固定在用于控制转向柱锁止状态的电机的输出轴上。本发明是应用于汽车电子转向柱锁的传动结构,采用一级传动机构,将蜗杆与斜齿轮进行了变位参数设计,且蜗杆的材料用黄铜来取代工程塑料,从而解决其强度和ESCL传动的寿命问题,极大地提高了ESCL的安装空间问题,通用性也随之提高,随着内部传动机构级数的减少,其产生异响的可能性降低,制造性、经济性也得到较大的提升。
