[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include four major types: hybrid electric vehicles (HEV), pure electric vehicles (BEV, including solar vehicles), fuel cell electric vehicles (FCEV), and other new energy vehicles (such as supercapacitors, flywheels and other high-efficiency energy storage devices). At the same time, in a pure electric vehicle, the battery is its heart. Similarly, in a hybrid vehicle, the battery can also be considered as another heart. However, when installing lithium battery packs in existing new energy vehicles, either there is no buffer structure, which is easily damaged after long-term bumps, or the buffer structure is too simple to achieve buffering of longitudinal and lateral external forces, with a low protection factor and average effect. Therefore, a lithium battery buffer device for new energy vehicles is needed to improve the above problems. Utility Model Content

A cavity 9 is arranged between the upper buffer plate 2 and the lithium battery pack 1. A fixed vertical rod 8 is vertically installed inside the cavity 9. The top of the upper buffer plate 2 and the bottom of the lower buffer plate 3 are both provided with mounting liner 5. A first damping spring 6 is fixedly connected between the mounting liner 5 and the upper and lower buffer plates 2 and 3. The lithium battery pack 1 is externally sleeved with a buffer ring frame 4, and mounting screw holes 14 are provided at the four corners of the buffer ring frame 4.

Action rings 11 are fixedly installed on both ends of the buffer sleeve 7. A rebound ring 10 is provided on the side of the action ring 11 away from the buffer sleeve 7. A second shock-absorbing spring 13 is fixedly connected between the rebound ring 10 and the action ring 11. The mounting liner 5 is completely attached to the upper and lower side walls of the internal mounting cavity of the new energy vehicle. The lithium battery pack 1 is placed between the mounting lining plates 5, and is fixedly mounted to the interior of the vehicle by mounting screw holes 14 provided at the four corners of the buffer ring frame 4 in combination with bolts.
