s3, after the automobile body is aligned and stabilized, the first hydraulic cylinder (507) on the right side works to drive the first hydraulic rod (508) to extend, the power supply tray (5010) is further driven to be attached to the storage battery on the bottom of the automobile, the fifth motor (509) works to drive the bolt dismounting rotary head (5011) to rotate reversely, a fixing bolt for fixing the storage battery on the bottom of the automobile is unscrewed, the first hydraulic rod (508) slowly shrinks when the fifth motor (509) rotates, the power supply tray (5010) is driven to slowly descend, after the storage battery on the bottom of the automobile is dismounted, the first hydraulic rod (508) shrinks to the bottom, the first hydraulic cylinder (507) on the left side works to drive the first hydraulic rod (508) to extend, the power supply tray (5010) is further driven to be attached to the bottom of the backup storage battery (3012) of the automobile, the bolt dismounting rotary head (5011) is driven to rotate reversely by the fifth motor (509) work, the fixing bolt for fixing the automobile spare storage battery (3012) is unscrewed, the first hydraulic rod (508) is slowly contracted when the fifth motor (509) rotates, then the power supply tray (5010) is driven to slowly descend, after the automobile spare storage battery (3012) is taken down, the first hydraulic rod (508) is contracted to the bottom, then the fourth motor (501) works to drive the second threaded rotating rod (502) to rotate to drive the second threaded sleeve (504) to move towards the right side, the bolt disassembly rotating head (5011) on the left side stops moving when corresponding to the fixing bolt hole of the automobile bottom storage battery, then the first hydraulic cylinder (507) on the left side works to drive the first hydraulic rod (508) to extend to enable the battery on the bolt disassembly rotating head (5011) to be attached to the mounting position, and then the power supply on the bolt disassembly rotating head (5011) is mounted to the bottom of the automobile through the positive rotation of the fifth motor (509), simultaneously, the first hydraulic cylinder (507) on the right side works to drive the first hydraulic rod (508) to extend to enable the bolt to detach the battery attaching and installing position on the rotating head (5011), then the power supply on the bolt detaching and rotating head (5011) is installed on the inner side of the automobile standby battery fixing plate (3011) through the positive rotation of the fifth motor (509), after the automobile is replaced with the battery, the second motor (308) rotates ninety degrees, the fully charged automobile standby battery (3012) is parallel to the ground, and the power supply can be replaced next time.
