Heavy truck and engine hood lock body assembly thereof
The invention discloses an engine hood lock body assembly which comprises a lock bottom plate, a lock hook with a mounting hole, a pin shaft fixed on the lock bottom plate and a torsional spring witha middle hole sleeving the pin shaft. The mounting hole of the lock hook sleeves the pin shaft and can rotate, the outer side of the lock bottom plate is provided with a notch, the lock hook is provided with a hook body capable of blocking the notch, the inner side of the lock hook is provided with a stopper, the first end of the torsional spring is fixed to the lock bottom plate, and the second end of the torsional spring is fixed to the stopper. When a lock catch impacts on an outer side impact point of the hook body, the lock hook can rotate towards the opposite side of an opening of the hook body, when the lock catch impacts on an inner side impact point of the hook body, the lock hook can rotate towards the same side of the opening of the hook body, and the lock hook can be driven torotate towards the opposite side of the opening of the hook body by pulling the inner side of the lock hook. The structure is simple, when the lock hook is closed, the lock catch impacts on the lock hook, and the lock hook is not prone to deformation and damage. The invention further discloses a heavy truck comprising the engine hood lock body assembly. The heavy truck has the same beneficial effects as those of the engine hood lock body assembly.
本发明公开了一种引擎盖锁体总成，包括锁底板、具有安装孔的锁钩、固定于锁底板上的销轴、中孔套装于销轴上的扭簧，锁钩的安装孔套装于销轴上且能够转动，锁底板的外侧具有缺口，锁钩具有能够封挡缺口的钩体，锁钩的内侧具有挡块，扭簧的第一端固定于锁底板上且第二端固定于挡块上，当锁扣撞击钩体的外侧撞击点时，能够使锁钩向钩体开口的反侧转动，当锁扣撞击钩体的内侧撞击点时，能够使锁钩向钩体开口的同侧转动，拉动锁钩的内侧能够驱动锁钩向钩体开口的反侧转动。结构简单，锁钩闭合状态下，锁扣撞击锁钩，锁钩不易变形损坏。本发明还公开了一种包括上述引擎盖锁体总成的重型卡车，其有益效果与引擎盖锁体总成的有益效果相同。
