The invention provides a truck blind area monitoring auxiliary device, which comprises a clamping mechanism, a bearing plate, a turning detection mechanism, a main control unit, an object detection mechanism and an alarm, and is characterized in that the turning detection mechanism is arranged at a tire arc-shaped position of a side plate of a truck head and comprises a magnetic block, a connecting plate, a force application spring, a pressure sensor and a convex block; the metal hub of the vehicle head wheel can rotate, the spacing distance between the metal hub and the two sides of the magnetic block changes, the magnetic force of the two sides of the magnetic block to the metal hub is different, at the moment, the magnetic block drives the connecting plate to deviate with the vertical line as the axis, and therefore the pressures provided by the two force application springs above the side wall of the connecting plate to the pressure sensor are different. The turning direction and the turning amplitude of the truck can be judged according to the pressure difference, so that the main control unit can control the laser radar to rotate and emit laser to detect whether other vehicles or pedestrians exist in a blind area of the truck or not, an alarm is conveniently given out in time for prompting, and traffic accidents are avoided.
本发明提供一种货车盲区监测辅助装置,包括夹紧机构、承载板、转弯检测机构、主控单元、物体检测机构以及报警器,转弯检测机构设置在货车车头侧板轮胎弧形位处,其包括磁性块、连接板、施力弹簧、压力传感器以及凸块,当货车转弯时,车头车轮的金属轮毂会发生转动,其与磁性块两侧的间隔距离发生改变,磁性块两侧对金属轮毂的磁力会存在差异,此时磁性块带动连接板以竖直线为轴发生偏移,从而连接板侧壁上方的两个施力弹簧提供给压力传感器的压力不同,通过压力的差异可以判断出货车转弯的方向以及转弯的幅度,从而主控单元可以控制激光雷达旋转并发出激光以检测货车盲区是否存在其他车辆或行人,以便于及时发出警报进行提示,避免发生交通事故。
