[0011] A logistics transportation method, which is applicable to the above-mentioned intelligent logistics transportation vehicle, comprises the following steps: S1: When the logistics transport vehicle has a tire burst during driving, the tire pressure drops rapidly, which may cause the logistics transport vehicle to shake violently. Therefore, when the logistics transport vehicle shakes, the movable ball inside the fixed frame can move, and when the movable ball triggers the corresponding trigger, the cylinder can be started; S2: When the cylinder is started, it can drive the pressing block to move downward and contact the tire surface to press the tire.

S4: When the dual-axis motor is started, the power output shaft can drive the two transmission rods to rotate. When the transmission rods rotate, the replacement plate can be turned over, thereby turning the positions of the two tires. When the position of the intact tire is adjusted, the servo motor drives the power output shaft to rotate in the opposite direction, thereby driving the wire tube to rotate in the opposite direction, reinstalling the fixing bolts, and completing the purpose of replacing the damaged tire; S5: When the tire needs to be removed, the lifting cylinder can be started. When the lifting cylinder is started, the power output shaft can drive the horizontal plate to move upward. When the horizontal plate moves upward, it can drive the moving block to move upward. When the moving block located at the top is active, the adjacent L-shaped active plate can drive the rotating plate to rotate. When the rotating plate rotates, it can drive the remaining moving blocks to move in opposite directions, thereby breaking away from the fitting state with the annular groove, so that the current tire is in a removable state.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention can realize that when a tire bursts on a logistics transport vehicle, the vehicle body can shake violently, and the movable ball can move according to the shaking of the vehicle, thereby activating the pressing block to detect the tire pressure of the four tires, thereby determining the location of the tire burst and initiating subsequent tire replacement operation steps, through the mutual cooperation between the movable ball, spring, fixed frame, balance plate, laminating plate, cylinder, pressing block, fixed block, L-shaped connecting plate and other components.

[0019] A logistics transportation method, which is applicable to the above-mentioned intelligent logistics transportation vehicle, comprises the following steps: S1: When the logistics transport vehicle has a tire burst during driving, the tire pressure of the tire 6 drops rapidly, which may cause the logistics transport vehicle to shake violently. Therefore, when the logistics transport vehicle shakes, the movable ball 28 inside the fixed frame 17 can move, and when the movable ball 28 triggers the corresponding trigger, the cylinder 14 can be started; S2: When the air cylinder 14 is started, the pressing block 32 can be driven to move downward and contact the surface of the tire 6 to press the tire 6. If the air pressure of the current tire 6 is slightly insufficient, the pressing block 32 can drive the laminating plate 27 to fit with the trigger block 29 located above, and remind the staff through the remote alarm system to inspect the current tire 6 when the vehicle returns. When the laminating plate 27 fits with the trigger block 29 located below, the dual-axis motor 5 can be started; S3: The adjacent groove wheel 11 can be driven to rotate by the power output shaft of the servo motor 26. When the front groove wheel 11 rotates, the other groove wheel 11 can be driven to rotate through the belt 10, thereby driving the connecting gear 18 to rotate. When the connecting gear 18 rotates, the movable gear 19 can be driven to rotate. When the movable gear 19 rotates, the wire tube 20 can be driven to rotate. When the wire tube 20 rotates, it can be engaged with the threaded hole and thus can be rotated and moved, thereby removing the fixing bolt 31 and making the tire 6 to be replaced active. S4: When the dual-axis motor 5 is started, the two transmission rods 3 can be driven to rotate through the power output shaft. When the transmission rods 3 rotate, the replacement plate 9 can be driven to flip, thereby flipping the positions of the two tires 6. When the position of the intact tire 6 is adjusted, the servo motor 26 drives the power output shaft to rotate in the opposite direction, thereby driving the wire tube 20 to rotate and move in the opposite direction, and the fixing bolts 31 are reinstalled, thereby completing the purpose of replacing the damaged tire 6. S5: When the tire 6 needs to be removed, the lifting cylinder 23 can be started. When the lifting cylinder 23 is started, the power output shaft can drive the horizontal plate 24 to move upward. When the horizontal plate 24 moves upward, it can drive the moving block 13 to move upward. When the moving block 13 located above is active, the adjacent L-shaped active plate 16 can drive the rotating plate 21 to rotate. When the rotating plate 21 rotates, it can drive the remaining moving blocks 13 to move in opposite directions, thereby breaking away from the fitting state with the annular groove, so that the current tire 6 is in a removable state.

[0020] Working principle: When the logistics transport vehicle has a tire burst during driving, the tire pressure of the tire 6 drops rapidly, which may cause the logistics transport vehicle to shake violently. Therefore, when the logistics transport vehicle shakes, the movable ball 28 inside the fixed frame 17 can move. When the movable ball 28 triggers the corresponding trigger, the cylinder 14 can be started. When the cylinder 14 is started, the pressing block 32 can be driven to move downward and contact the surface of the tire 6 to press the tire 6. If the current tire 6 pressure is slightly insufficient, the pressing block 32 can drive the fitting The plate 27 is fitted with the trigger block 29 located above, and the remote alarm system is used to remind the staff that when the vehicle returns, the current tire 6 is inspected. When the fitting plate 27 is fitted with the trigger block 29 located below, the dual-axis motor 5 can be started, and the adjacent groove wheel 11 can be driven to rotate through the servo motor 26 power output shaft. When the current groove wheel 11 rotates, the other groove wheel 11 can be driven to rotate through the belt 10, thereby driving the connecting gear 18 to rotate. When the connecting gear 18 rotates, the movable gear 19 can be driven to rotate. When the movable gear 19 rotates, the wire tube 20 can be driven. When the wire tube 20 rotates, it engages with the threaded hole and can be rotated to remove the fixing bolt 31, so that the tire 6 to be replaced is in an active state. When the dual-axis motor 5 is started, the two transmission rods 3 can be driven to rotate through the power output shaft. When the transmission rods 3 rotate, the replacement plate 9 can be driven to flip, thereby flipping the positions of the two tires 6. When the position of the intact tire 6 is adjusted, the servo motor 26 drives the power output shaft to rotate in the opposite direction, thereby driving the wire tube 20 to rotate in the opposite direction, and reinstalling the fixing bolt 31 is completed. For the purpose of replacing the damaged tire 6, when the tire 6 needs to be removed, the lifting cylinder 23 can be started. When the lifting cylinder 23 is started, the cross plate 24 can be driven to move upward through the power output shaft. When the cross plate 24 moves upward, it can drive the moving block 13 to move upward. When the moving block 13 located above is active, the rotating plate 21 can be driven to rotate through the adjacent L-shaped movable plate 16. When the rotating plate 21 rotates, it can drive the remaining moving blocks 13 to move in opposite directions, thereby breaking away from the fitting state with the annular groove, so that the current tire 6 is in a removable state.
