Tail door lock structure with snow loading function, tail door lock and vehicle
The tail door lock structure with the snow loading function comprises a ratchet wheel, the ratchet wheel is connected to a bottom plate through a first rotating shaft, a pawl is connected to the bottom plate through a second rotating shaft, the outer surface of the second rotating shaft is sleeved with an opening rocker arm, a clamping hook part is arranged in the middle of the opening rocker arm, and a stopping block is arranged at the tail end of the clamping hook part; a first guide convex rib is arranged on the ratchet wheel, the section of the first guide convex rib is in a right triangle shape, and when the rocker arm is started to rotate, the stopping block can cross over the first guide convex rib from the end, close to the center of the ratchet wheel, of the first guide convex rib and cannot cross over the first guide convex rib from the end, away from the center of the ratchet wheel, of the first guide convex rib. After the starting rocker arm is driven to rotate and the stop block is driven to cross the first guide convex rib, the right-angle side of the first guide convex rib abuts against the stop block, so that the stop block cannot cross the first guide convex rib in the opposite direction, a certain distance is kept between the pawl and the ratchet wheel, and the pawl and the ratchet wheel cannot be buckled again under the gravity effect of accumulated snow.
本发明提供一种具有雪载功能的尾门锁结构，包括棘轮，棘轮通过第一转轴连接于底板上，棘爪通过第二转轴连接于底板上，第二转轴外表面套设有开启摇臂，开启摇臂中部设置有卡钩部，卡钩部的末端设置有阻挡块，棘轮上设置有第一导向凸筋，第一导向凸筋的剖面呈直角三角形，当开启摇臂旋转时，阻挡块能够从第一导向凸筋靠近棘轮中心的一端越过第一导向凸筋，而不能从第一导向凸筋远离棘轮中心的一端越过第一导向凸筋。本发明通过驱动开启摇臂旋转，带动阻挡块越过第一导向凸筋后，第一导向凸筋的直角边抵住阻挡块，使得阻挡块不能反方向越过第一导向凸筋，从而保持棘爪和棘轮有一定的间距，致使棘爪和棘轮不会在积雪的重力作用下重新扣合。
