The annular shell (401) is installed on the equipment housing (5) and divides the equipment housing (5) into two parts. The guide rod (305) passes through the inner ring of the rotating ring (402). The inner wall of the rotating ring (402) is fixedly installed with multiple sets of circumferentially arrayed protrusions (403), and the top of the protrusions (403) is an arc surface structure; The telescopic collision device (108) includes a telescopic device (1081). There are two sets of telescopic devices (1081), with two in each set. The two sets of telescopic devices (1081) are in opposite directions. The telescopic devices (1081) are fixed on the bottom surface of the battery transport platform (101). A collision wheel (1082) is installed at the output end of any telescopic device (1081). When the telescopic device (1081) extends, the collision wheel (1082) can contact the protrusion (403) inside the rotating ring (402). The transverse axis of the collision wheel (1082) corresponds to the transverse axis of the rotating ring (402).

8. The bump testing device for new energy batteries according to claim 7, characterized in that: The inner wall of the annular shell (401) is fixedly installed with multiple sets of support wheels (404), which clamp the rotating ring (402) to keep it rotating concentrically with the annular shell (401). The inner wall of the annular shell (401) is also fixedly installed with a motor (405), which drives the rotating ring (402) to rotate through gear meshing.

9. The bump testing device for new energy batteries according to claim 8, characterized in that: The upper end of the equipment housing (5) is equipped with multiple maintenance doors (6).
