The invention discloses an automobile time-sharing four-wheel-drive switch. The four-wheel-drive switch comprises a shell; a knob; the driving part is arranged in the shell and is connected to the knob, so that the driving part is driven to rotate through the rotation of the knob; the contact mechanism comprises a first contact, a plurality of second contacts respectively corresponding to the plurality of driving modes, and a switch piece which is driven by the driving piece and is used for conducting the first contact and any second contact; the over-rotation preventing mechanism comprises a first elastic piece which is arranged on the driving piece and applies elastic force to the driving piece, and a support body arranged on the driving piece; wherein a guide plate is arranged in the shell, a first guide structure and a second guide structure are arranged on the side, facing the support body, of the guide plate, and a blocking rib used for blocking the support body from directly moving towards the 4L mode is formed at the joint of the first guide structure and the second guide structure. According to the invention, the technical defect in the prior art that when the four-wheel drive switch is rotated from 2H to 4H, the four-wheel drive switch is easy to excessively twist to turn to a 4L state can be solved.

    本发明公开了一种汽车分时四驱开关,该四驱开关包括:壳体;旋钮;驱动件,设于壳体内且连接于旋钮,以通过旋钮的转动带动驱动件转动;触点机构,包括第一触点、与多种驱动模式分别对应的多个第二触点,以及由驱动件驱动用于导通第一触点与任一个第二触点的开关件;防过转机构,包括设于驱动件之上向驱动件施加弹性力的第一弹性件,以及设于驱动件之上的支架主体;其中,壳体内设有一导向板,导向板朝向支架主体的一侧设有第一导向结构与第二导向结构,第一导向结构与第二导向结构的结合处形成有用于阻挡支架主体直接向4L模式运动的阻挡筋条。本发明能够解决现有技术中四驱开关由2H转动至4H时,比较容易过度扭转而转向4L状态的技术不足。
