Description

technical field [0001] The invention relates to a heavy-duty vehicle rear protection device, in particular to a double crank slider type heavy-duty vehicle rear protection device. Background technique [0002] At present, the rear protection devices of various heavy vehicles at home and abroad all adopt a mechanical structure of purely rigid connection. That is, the rear bumper is fixedly connected with the vehicle frame directly through the bracket. This purely rigidly connected rear protection device will not only affect the passability of heavy vehicles, but will also be damaged due to the vehicle running under harsh road conditions, thus causing it to fail to perform its protective function. At the same time, this traditional rear protection device is relatively high from the ground and cannot adjust the height of the rear bumper from the ground. When different types of vehicles such as cars or SUVs collide with heavy vehicles, it cannot achieve a good anti-penetration ...
