The application discloses a kind of electric vehicle double battery switching endurance methods.The application is independently set by lead-acid battery group, lithium battery group on electric vehicle, respectively configure exclusive independent control switch, corresponding switch is manually operated and is started and stopped operation by key, the independent on-off and switching use of two groups of batteries are realized, the battery functions of two electric vehicles are combined, the endurance capability of electric vehicle is significantly improved.The method avoids existing automatic switching, parallel switching and other technologies, adopts pure manual independent switching mode, the structure is simple, convenient to operate, switching logic is clear, and endurance capability can be doubled through test verification, and through specific switch linkage design avoids circuit conflict in switching process, solves the drawbacks that double battery switching in existing technology is prone to power supply anomaly and cannot be switched stably, and is suitable for various electric bicycles, electric motorcycles and other electric vehicle models.

The utility model relates to the technical field of furniture hardware fittings, propose a kind of hinge with opening and closing buffer, including the bufferer being arranged in hinge casing and the hinge cup being connected with outer rocker arm assembly, outer rocker arm assembly one end rotationally arranged in hinge casing;The bufferer is transversely arranged along the length direction of hinge casing, and cooperate with it when outer rocker arm assembly rotates, outer rocker arm assembly rotates to the position of bufferer when in hinge opening process, to realize the buffer opening of hinge.The hinge with opening and closing buffer is transversely arranged along the length direction of hinge casing, so that outer rocker arm assembly can interact with bufferer in opening and closing process.Compared with the bufferer of traditional vertical arrangement, this transverse arrangement can more effectively utilize the internal space of hinge casing, so that the installation position of bufferer is more reasonable.
