[0002] In the field of automobile wiper technology, the wiping angle of the wiper plays a key role in its performance and safety. However, the existing wiper angle detection device can only be limited to detecting the wiping angle of a single position of the wiper, and cannot comprehensively and accurately obtain the angle information of the wiper at different positions in the entire wiping area, resulting in serious data omissions when evaluating the performance of the wiper, and it is difficult to determine whether it can effectively wipe water at different positions. At the same time, when it is necessary to have an in-depth understanding of the wiping angle of the wiper at multiple positions, due to the single function of the existing device, different angle detection devices have to be frequently replaced. This process is not only cumbersome and complicated to operate, and consumes a lot of time and manpower, but is also very likely to cause large deviations in the detection results due to errors and inconsistencies in the device replacement process, which seriously restricts the efficiency and accuracy of wiper detection technology and is difficult to meet the growing demands of modern automobile wiper research and development, production and quality control.

The first special-shaped portion 1215 and the second special-shaped portion 1216 are perpendicular to each other, which cleverly changes the force transmission direction and angle, making the movement of the entire connecting rod assembly 121 more flexible and diverse to meet different simulated wiping action requirements. One end of the fourth connecting rod 1213 and the other end of the second connecting rod 1211 are connected to the first special-shaped portion 1215 of the third connecting rod 1212, and one end of the support rod 120 is connected to the second special-shaped portion 1216 of the third connecting rod 1212; the first connecting rod 121 0 is fixedly connected to the output shaft of the gear box 111, and the other end thereof is rotatably connected to one end of the second connecting rod 1211 by means of a shaft pin or the like, so that the two can rotate relative to each other; the other end of the second connecting rod 1211 is rotatably connected to the first special-shaped portion 1215 of the third connecting rod 1212, the second special-shaped portion 1216 of the third connecting rod 1212 is rotatably connected to one end of the support rod 120, and one end of the fourth connecting rod 1213 is also connected to the first special-shaped portion 1215 of the third connecting rod 1212, and is arranged opposite to the second connecting rod 1211; the other end of the fourth connecting rod 1213 is rotatably connected to one end of the fifth connecting rod 1214, and the other end of the fifth connecting rod 1214 is rotatably connected to the other end of the support rod 120 Dynamic connection. Through this sequential connection mode, when the gear box 111 drives the first connecting rod 1210 to rotate, the support rod 120 is driven to realize a swing similar to that of a wiper through the transmission between the connecting rods. Since the movement of the first connecting rod 1210 is directly related to the movement state of the entire swing arm assembly 12, the detection device 3 can indirectly obtain the wiping angle of the wiper by detecting the swing angle of the first connecting rod 1210. Through the coordinated work and clever connection of multiple connecting rods, the complex swing trajectory of the wiper in actual use can be accurately simulated, making the simulation effect more realistic, providing a reliable and convenient data acquisition method, and helping to improve the quality control level of wiper research and development and production.
