2results about How to "Change impact" patented technology

The application belongs to the technical field of battery accessory testing, and particularly relates to a power impact testing system for new energy vehicles, which comprises a bottom plate, a fixing mechanism for fixing the position of a power supply is arranged on the upper surface of the bottom plate, two supporting plates are fixedly connected to the bottom plate, a guide groove is arranged in the supporting plate, a top plate is fixedly connected to the two supporting plates, a hydraulic cylinder is fixedly installed on the top plate, a driving pressing plate is fixedly connected to the output end of the hydraulic cylinder, and a sliding block is slidably connected to the guide groove. The impact force of an impact head on the power supply can be changed by adjusting the hydraulic pressure of the hydraulic cylinder, the value of the impact force can be accurately measured and read by a pressure measuring plate, the power supply is limited and fixed by the fixing mechanism, so that the power supply is prevented from shaking and deviating when being impacted by the impact head, and the power supply surface can be sprayed with fire extinguishing agent by the fire extinguishing mechanism, so that the power supply is prevented from being deformed and damaged due to fire.

The utility model relates to a structure of guiding airflow shunting, which is located at the outside of the automobile rearview mirror shell, comprising a rearview mirror shell, a plurality of shunting devices of guiding airflow shunting arranged outside the rearview mirror shell, the shunting device is a plurality of convex strips or groove strips with an elongated structure from top to bottom, if the shunting device is a plurality of convex strips, the width of the convex strip from the car to the rear view increases gradually, the height increases gradually, and the length increases gradually, if the shunting device is a plurality of groove strips, the width of the groove strip from the car to the rear view decreases gradually, the height decreases gradually, and the length decreases gradually, and the spacing between adjacent convex strips or groove strips gradually increases from the car to the rear view. The structure of guiding airflow shunting provided by the utility model changes the airflow structure of the automobile rearview mirror, increases the airflow shunting structure through the appearance modeling structure design, orderly guides the airflow in the flowing process, reduces the occurrence of noise, and changes the influence of the airflow on the rearview mirror.
