Because the AGV robot 500 has a navigation module to drive the AGV robot 500 to displace to the battery position 510 of the electric vehicle 100 to be replaced, there is no special limitation on the parking of the electric vehicle 100 to be replaced, and after the electric vehicle 100 to be replaced is parked in place, the AGV robot 500 actively identifies the vehicle position to perform navigation driving.

Example two

Referring to fig. 1, 2 and 3, a second embodiment of the present application provides a battery replacement method for replacing a battery of a vehicle 100 to be replaced. The method for replacing batteries of the vehicle 100 to be replaced by using the battery replacement station 001 provided in the first embodiment includes:

s101: the vehicle 100 to be switched enters the battery switching parking place 200 in any posture;

s301: the electricity taking device 400 takes out the first battery from the battery compartment 310 of the power vending apparatus 300;

s302: the AGV robot 500 receives a first battery of the power taking device 400 to a battery position 510;

s303: the AGV robot 500 moves to a battery vacant position of the electric vehicle 100 to be replaced through the driving module and the navigation module;

s304: the AGV robot 500 transfers the first battery in the battery position 510 to a battery empty position;

s401: the standby electric vehicle 100 locks the first battery.

The driver or the unmanned vehicle 100 to be switched drives into the battery changing parking space 200, and the battery changing parking space 200 has surplus space after the vehicle 100 to be switched is parked. The battery replacing vehicle space 200 can reduce the technical requirements of the driver because a larger space is provided for parking the vehicle 100 to be replaced, and can also reduce the manual intelligent calculation amount when the vehicle 100 to be replaced is an unmanned vehicle. The vehicle 100 to be switched does not have specific parking requirements in the battery switching space 200, and only needs to enter the battery switching space 200, and the battery switching station 001 can be started to switch the battery when the vehicle 100 to be switched is parked in any posture on the battery switching space 200.

After the battery replacing station 001 is started to perform battery replacing operation, the AGV robot 500 takes down the first battery from the power taking device 400, guides the driving module to operate through the navigation module, conveys the first battery to the battery vacant position of the vehicle 100 to be replaced, and transmits the first battery to the battery vacant position, so that the vehicle 100 to be replaced has the first battery installed. The navigation module and the drive module of AGV robot 500 self are passed through in whole process and are treated the affirmation of trading electric vehicle 100 position for AGV robot 500 can find the electric vehicle 100 that waits to trade of arbitrary gesture on trading electric parking stall 200, consequently has no restriction to the parking gesture of vehicle in this great region of trading electric parking stall 200, as long as in trading electric parking stall 200, AGV robot 500 can both initiatively go to look for the vehicle and match the parking gesture of vehicle.

If the location where the first battery needs to be installed on the electric vehicle 100 to be replaced already has the second battery, the second battery on the electric vehicle 100 to be replaced also needs to be taken down, so the method further comprises the following steps before step S202:

s201: the AGV robot 500 moves to a battery loading position of the electric vehicle 100 to be replaced through the driving module and the navigation module; and the combination of (a) and (b),

s202: the AGV robot 500 takes the second battery from the battery loading position to the battery station 510.

The navigation module and the driving module of the AGV robot confirm the position of the vehicle 100 to be replaced, so that the AGV robot 500 can find the vehicle 100 to be replaced in any posture on the battery replacing vehicle space 200 and butt-joint the battery loading position of the vehicle 100 to be replaced. After the AGV robot 500 completes docking with the battery loading position, the AGV robot 500 takes out the second battery at the battery loading position.

In order to further reduce the size of the AGV robot 500, the AGV robot 500 only has one battery position 510, and the size reduction of the robot can make the AGV robot 500 move in a narrower place, but the AGV robot 500 having only one battery position 510 cannot simultaneously carry the first battery and the second battery. Therefore, after step S202, the method further includes the steps of:

s203: the AGV robot 500 moves to the transfer bay 600 and the transfer bay 600 receives the second battery from the battery bay 510.

Temporary storage of the battery is achieved by the transfer bin 600, and the battery 510 of the AGV robot 500 can be left empty for subsequent first battery transportation.

In order to provide a straight path as much as possible while the AGV robot 500 is displacing to the battery empty position of the vehicle 100 to be changed, it is necessary that the AGV robot 500 have an overall path plan. For this purpose, step S303 specifically includes the steps of:

s303 a: the navigation module shoots the appearance information of the electric vehicle 100 to be replaced through the camera 550 to provide a driving signal for the driving module.

The camera 550 is used for shooting the shape information of the electric vehicle 100 to be replaced to determine the approximate range of the battery vacant position, so as to provide a straight path for the driving module to approach the approximate range of the determined battery vacant position.

After the AGV robot 500 approaches the approximate range of the battery empty position, the AGV robot 500 needs to perform fine adjustment again to dock the battery position 510 with the battery empty position, and therefore the step S303 specifically further includes:

s303 b: the navigation module is butted with a positioning piece of the vehicle 100 to be changed through the laser positioning head 530;

s303 c: when the laser positioning heads 530 with the preset number on the navigation module and the positioning pieces are in a butt joint state at the same time, the AGV robot 500 is in butt joint with the vacant battery position;

s303 d: when the laser positioning heads 530 and the positioning members in the preset number on the navigation module cannot be in the butt joint state at the same time, the AGV robot 500 continuously adjusts the posture.

Wherein, the steps S303c and S303d include a determination behavior, and the AGV robot 500 repeatedly performs S303d to approach the implementation condition of S303c before implementing S303c in the fine adjustment process.

Similarly, in order to provide a path as straight as possible while the AGV robot 500 is moving to the battery loading position of the vehicle 100 to be replaced, it is necessary that the AGV robot 500 have an overall path plan. For this purpose, step S201 specifically includes the steps of:

s201 a: the navigation module shoots the appearance information of the electric vehicle 100 to be replaced through the camera 550 to provide a driving signal for the driving module.

s201 b: the navigation module is butted with a positioning piece of the vehicle 100 to be changed through the laser positioning head 530;

s201 c: when the laser positioning heads 530 with the preset number on the navigation module and the positioning pieces are in a butt joint state at the same time, the AGV robot 500 is in butt joint with the battery loading position;

s201 d: when the laser positioning heads 530 and the positioning members in the preset number on the navigation module cannot be in the butt joint state at the same time, the AGV robot 500 continuously adjusts the posture.

Wherein, the steps S201c and S201d include a determination behavior, and the AGV robot 500 repeatedly performs S201d to approach the implementation condition of S201c before implementing S201c in the fine adjustment process.

It should be noted that, in other embodiments, after the AGV robot 500 and the vehicle 100 to be powered off are docked once in step S201, the path in step S201 is used in step S303 without performing navigation again, but in this way, there is a case where the path is changed due to other circumstances, for example, when the AGV robot 500 executes step S303, the power change car space 200 enters a dynamic object to block the movement of the AGV robot 500, so that the path is changed.

In order to reduce the overall thickness of the AGV robot 500 and enable the AGV robot 500 to perform a battery replacement operation for a vehicle with a lower chassis, please refer to fig. 4, 5, 6 and 7, a lifting mechanism is installed in the AGV robot 500 to lift the battery in the battery position 510, so that the step S304 includes the steps of:

s304 a: the AGV robot 500 lifts the first battery in the battery bay 510 into a battery empty position via the lifting structure 570.

After the first battery is transferred to the battery empty position, the vehicle 100 to be powered off needs to lock the first battery to drive the first battery to move synchronously. The electric vehicle 100 to be replaced needs to be locked after confirming that the first battery has entered the battery empty position and can be locked, and therefore, after step S304, the method further includes the steps of:

s305: the AGV robot 500 sends a locking signal to the vehicle 100 to be replaced, so that the vehicle 100 to be replaced locks the first battery in the battery empty position.

In order to confirm whether the path of the AGV robot 500 is correct, the end of the electric vehicle 100 to be replaced needs to confirm the path, and for this reason, the electric vehicle 100 to be replaced needs to exchange information with the AGV robot 500, specifically, the step S303 further includes:

s303 e: the near field communication module of the AGV robot 500 exchanges the confirmation information to the vehicle 100 to be changed, and the AGV robot 500 determines whether to approach the battery vacant position according to the confirmation information.

Whether the traveling direction of the AGV robot 500 is correct or not can be judged by docking the near field communication module with the vehicle, and if the near field communication module is successfully docked with the vehicle, it is indicated that the AGV robot 500 has the correct traveling direction and has traveled to the vicinity of the battery vacant position.
