Description
技术领域technical field
本实用新型属于汽车配件技术领域，具体涉及一种消除大型汽车内轮差盲区的装置。The utility model belongs to the technical field of auto parts, and in particular relates to a device for eliminating the blind spot of the inner wheel difference of a large automobile.
背景技术Background technique
大型车辆(包括城市公交车、渣土车、水泥罐车、大型客车和半挂拖车等)在转弯时，后轮并不是沿着前轮的轨迹行驶，会产生偏差，转弯形成的偏差叫“轮差”；车身越长，形成的“轮差”就越大，内轮差的范围也会跟着扩大，大型汽车的内轮差一般在2至6米。When large vehicles (including city buses, muck trucks, cement tankers, large passenger cars and semi-trailers, etc.) turn, the rear wheels do not run along the track of the front wheels, and deviations will occur. The deviations formed by turning are called "wheels". The longer the body, the greater the "wheel difference" formed, and the range of the inner wheel difference will also expand. The inner wheel difference of a large car is generally 2 to 6 meters.
如图1所示，半挂拖车后视镜的可视范围在网格区域，随着半挂拖车的右转弯，牵引车和挂车的夹角越来越大，驾驶员通过后视镜获得的车体后侧信息也就越来越少。而后视镜视野所达不到车身周边范围，恰好处在半挂拖车的转弯内轮差区域内，驾驶员也就不能及时发现内轮差区域内的行人和非机动车。As shown in Figure 1, the visible range of the rear-view mirror of the semi-trailer is in the grid area. As the semi-trailer turns right, the angle between the tractor and the trailer becomes larger and larger. There is less and less information on the rear side of the car body. The rear-view mirror field of vision does not reach the surrounding area of the body, and it happens to be in the inner wheel difference area of the semi-trailer trailer, so the driver cannot detect pedestrians and non-motor vehicles in the inner wheel difference area in time.
由于大型汽车的驾驶员不能及时发现内轮差区域内的行人和非机动车，而将行人或非机动车驾驶人撞倒，经后车轮碾压并致其重伤或死亡的恶性事故常有发生。Because the driver of a large car cannot detect the pedestrians and non-motor vehicles in the inner wheel difference area in time, and knocks down the pedestrian or non-motor vehicle driver, and the rear wheel is run over and causes serious injury or death The vicious accident often occurs .
发明内容SUMMARY OF THE INVENTION
针对现有技术的不足，本实用新型提供了一种消除大型汽车内轮差盲区的装置。解决了大型汽车转弯时，驾驶员在内轮差区域内的视觉盲区的问题，保证了大型汽车的行车安全性。Aiming at the deficiencies of the prior art, the utility model provides a device for eliminating the blind spot of the inner wheel difference of a large automobile. It solves the problem of the driver's visual blind spot in the inner wheel difference area when the large car turns, and ensures the driving safety of the large car.
为实现上述目的，本实用新型发明的一种消除大型汽车内轮差盲区的装置，包括左摄像头、右摄像头、左视频显示屏、右视频显示屏以及电源线和视频传输线。In order to achieve the above purpose, the utility model invented a device for eliminating the blind spot of the inner wheel difference of a large automobile, which includes a left camera, a right camera, a left video display screen, a right video display screen, a power cord and a video transmission line.
进一步地，所述左摄像头、右摄像头分别安装在大型汽车尾部左、右两侧，并且左摄像头、右摄像头摄影方向都朝向大型汽车车头。Further, the left camera and the right camera are respectively installed on the left and right sides of the rear of the large car, and the photographing directions of the left camera and the right camera both face the front of the large car.
进一步地，所述左摄像头、右摄像头通过视频传输线分别与驾驶室内左视频显示屏、右视频显示屏相连接。Further, the left camera and the right camera are respectively connected with the left video display screen and the right video display screen in the cab through a video transmission line.
进一步地，所述左摄像头、右摄像头、左视频显示屏、右视频显示屏用电源线与供电端子相连接。Further, the left camera, the right camera, the left video display screen, and the right video display screen are connected to the power supply terminals with power cables.
进一步地，随着大型汽车转弯，驾驶员通过后视镜获得的车体后侧信息也就越来越少，而后视镜视野所达不到车身周边范围且恰好处在大型汽车的转弯内轮差区域时，左摄像头、右摄像头将采集大型汽车的转弯内轮差区域内的路面情况，并通过视频传输线传输给左视频显示屏、右视频显示屏。Further, as the large car turns, the driver obtains less and less information on the rear side of the car body through the rearview mirror, and the rearview mirror field of view cannot reach the surrounding area of the car body and is just in the turning inner wheel of the large car. When there is a difference area, the left camera and the right camera will collect the road conditions in the wheel difference area within the turning of the large car, and transmit them to the left video display screen and the right video display screen through the video transmission line.
进一步地，在上述情况下，驾驶员通过左视频显示屏、右视频显示屏可观察到大型汽车的转弯内轮差区域内的行人和非机动车，而及时采取相应的措施，从而避免将行人或非机动车驾驶人撞倒和碾压的恶性事故的发生。Further, in the above situation, the driver can observe pedestrians and non-motor vehicles in the wheel difference area of the large vehicle through the left video display screen and the right video display screen, and take corresponding measures in time to avoid pedestrians. Or the occurrence of vicious accidents in which drivers of non-motor vehicles are knocked down and run over.
