The invention belongs to the field of truck transformation, and particularly relates to an automatic covering device for a truck roof. The automatic covering device comprises a front awning, a middleawning and a rear awning which are arranged on a cargo compartment, and further comprises a front supporting arm, a rear supporting arm and a hydraulic cylinder which are connected with the cargo compartment and the middle awning; and the device also includes a front connecting rod, a front driving connecting rod and a front driving rod which are connected with the middle awning and the front awning, and a rear connecting rod, a rear driving rod connecting rod and a rear driving rod which are connected with the middle awning and the rear awning. The front awning, the middle awning and the rearawning are movably connected and foldable through the supporting arms and the connecting rods, and the three awning bodies (the front awning, the middle awning and the rear awning) directly cover thecargo compartment or are folded and placed at the top of a cockpit through rotation of the supporting arms around a shaft. Automatic covering and storing of the truck roof are achieved through a four-connecting-rod mechanism combined structure driven by the hydraulic cylinder; and compared with the prior art, the automatic covering device is simple in structure, transmission of belt wheels, storing ropes and other parts in the middle link is reduced, the fault rate of the device is reduced, and the efficiency of covering and storing the roof is improved.
本发明属于卡车改造领域,具体涉及一种一种卡车顶篷自动覆盖装置。包括:设置于货厢上的前篷、中篷、后篷,还包括连接货厢和中篷的前支撑臂、后支撑臂、液压缸,还包括连接中篷和前篷的前连杆、前驱动连杆、前驱动杆,还包括连接中篷和后篷的后连杆、后驱动杆连杆、后驱动杆;即通过支撑臂和连杆将前篷、中篷、后篷活动连接可折叠,通过支撑臂绕轴旋转,直接将三块顶篷(前篷、中篷、后篷)覆盖在货厢上,或收起折叠放置于驾驶舱顶部;通过液压缸驱动的四连杆机构组合结构实现自动覆盖和收纳卡车顶篷,向比较现有技术,结构简单,减少中间环节的皮带轮、收纳绳等零部件传动,减少了装置本身的故障率,并且提高了覆盖和收纳顶篷的效率。
