DETAILED DESCRIPTION

The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

Example 1

As shown in Figures 1 and 2, the battery swap station of the embodiment of the present invention includes a battery swap device. The battery swap device includes a first battery swap device 1 and a second battery swap device 2, which are respectively arranged on the left and right sides of the electric vehicle 10 and are used to replace the battery from the side of the electric vehicle 10. The first battery swap device 1 and the second battery swap device 2 both include a horizontal walking mechanism, a frame 11 and a battery pick-up and placement mechanism 12. The horizontal walking mechanism is arranged at the bottom of the frame 11, and the battery pick-up and placement mechanism 12 is arranged in the frame 11. The horizontal walking mechanism drives the frame 11 to move horizontally along the left and right sides of the electric vehicle 10.

The horizontal walking mechanism will move horizontally and drive the frame 11 and the battery pick-and-place mechanism 12 to move horizontally, so that the battery pick-and-place mechanism 12 on the first battery exchange device 1 and the second battery exchange device 2 can move horizontally on the left and right sides of the electric vehicle 10. The battery pick-and-place mechanism 12 can be used to pick and place the battery pack 101 on the electric vehicle 10, thereby realizing the battery exchange operation. The first battery exchange device 1 and the second battery exchange device 2 are respectively arranged on the left and right sides of the electric vehicle 10 and perform the battery exchange operation on the electric vehicle 10, thereby reducing the time spent on the battery exchange operation of the battery exchange equipment, thereby greatly improving the battery exchange efficiency of the battery exchange station.

The tops of the first battery exchange device 1 and the second battery exchange device 2 are connected by a connector 3 so that the first battery exchange device 1 and the second battery exchange device 2 can move synchronously. The bottom of the frame 11 will be connected to the horizontal walking mechanism to achieve horizontal movement, and the tops of the first battery exchange device 1 and the second battery exchange device 2 will be connected by the connector 3, thereby omitting the need to install the upper track, the mounting bracket for installing the upper track and other installation reinforcement structures, greatly saving costs, and easy installation and use. At the same time, the first battery exchange device 1 and the second battery exchange device 2 will achieve synchronous horizontal movement to realize the replacement operation of the battery pack 101 on the left and right sides of the electric vehicle 10, greatly improving the battery replacement efficiency and stability of the battery replacement station.

In this embodiment, the battery swap station further includes a plurality of lower rails 6. Since the tops of the first battery swap device 1 and the second battery swap device 2 are connected by a connector 3, the battery swap station may not include an upper rail, and the plurality of lower rails 6 are respectively arranged on the left and right sides of the electric vehicle 10, and the horizontal walking mechanism is slidably arranged on the lower rails 6. The horizontal walking mechanism will move on the lower rails 6, which greatly improves the stability of the battery swap device.

The first battery exchange device 1 and the second battery exchange device 2 also include a car 13 and a lifting mechanism, the lifting mechanism is arranged on the frame 11, the lifting mechanism is connected to both ends of the car 13 and is used to drive the car 13 to move up and down, and the battery pick-up and placement mechanism 12 is connected to the car 13. The lifting mechanism will be used to drive the car 13 to move up and down in the frame 11, thereby driving the battery pick-up and placement mechanism 12 to move up and down, so that the battery pick-up and placement mechanism 12 can accurately locate and realize the pick-up and placement of the battery pack 101, thereby improving the stability of the battery exchange equipment.

Both ends of the car 13 are slidably mounted on the frame 11. The two ends of the car 13 are lifted and moved in the frame 11, thereby effectively avoiding the displacement and dislocation of the car 13 during the lifting and moving process, and greatly improving the stability of the battery replacement equipment. Among them, guide parts can be set at both ends of the frame 11, and the two ends of the car 13 will cooperate and move up and down on the guide parts.

During the disassembly and assembly of the battery pack 101 on the electric vehicle 10, the overall weight of the electric vehicle 10 will decrease or increase, causing the electric vehicle 10 to float. In order to limit the floating of the electric vehicle 10, the first battery exchange device 1 and/or the second battery exchange device 2 may also include a fixed arm, which is connected to the car 13, and the fixed arm is used to lift and fix the electric vehicle 10 upward. The car 13 can be lifted and moved on the frame 11, which will drive the fixed arm to move up and down together. During the battery exchange process, the fixed arm will rise upward and lift the electric vehicle 10, so that the electric vehicle 10 will be against the force on the fixed arm due to the action of gravity. The electric vehicle 10 will be positioned in the vertical direction through the fixed arm, and the electric vehicle 10 will be positioned as a rigid body, which effectively prevents the electric vehicle 10 from causing the body to deviate and tilt during the replacement of the battery pack 101, affecting the battery exchange, and greatly improving the stability and reliability of the battery exchange station. After the replacement is completed, the fixed arm will drop downward, so that the wheels of the electric vehicle 10 can touch the ground.

Of course, the battery exchange equipment does not need to be installed with a fixed arm and lift the electric vehicle 10, and a follow-up function can be added to the battery exchange equipment. The first battery exchange device 1 and the second battery exchange device 2 can also include a position detection device, which is connected to the battery pick-up and placement mechanism 12, and the position detection device is used to detect the specific position of the battery pack 101 on the electric vehicle 10. The position detection device is used to detect the specific position of the battery pack 101 on the electric vehicle 10, so that the battery pick-up and placement mechanism 12 can accurately locate the specific position of the battery pack 101 and perform pick-up and placement operations on the battery pack 101, which greatly improves the stability of the battery exchange equipment. Among them, the position detection device can be a locator, a sensor, etc.

The first battery exchange device 1 and the second battery exchange device 2 also include an unlocking mechanism, which is arranged on the battery access mechanism 12 and is used to unlock or lock the locking mechanism on the battery pack 101. When the battery exchange device replaces the battery pack 101, the unlocking mechanism is used to unlock or lock the locking mechanism on the battery pack 101.

The battery swap station may also include a battery swap room 4 and a charging room 5. Both the charging room 5 and the battery swap room 4 are located between the first battery swap device 1 and the second battery swap device 2, and the charging room 5 is disposed above the battery swap room 4. The electric vehicle 10 will drive into the battery swap room 4 to implement battery swap. By disposing the charging room 5 above the battery swap room 4, the charging room 5 no longer occupies space, thereby effectively reducing the overall footprint of the battery swap station. At the same time, when the battery swap equipment is performing a battery swap operation, the battery pick-up and placement mechanism 12 only needs to be lifted and moved to move back and forth between the charging room 5 and the battery swap room 4, so that the battery swap equipment can replace the battery pack 101 without rotating, reducing the setting and installation of the rotating mechanism, thereby reducing the overall complexity of the battery swap equipment and reducing costs.

A vehicle positioning device is provided in the battery exchange room 4, and the vehicle positioning device is used to define the position of the electric vehicle 10 when replacing the battery pack 101. The vehicle positioning device is used to fix the electric vehicle 10, thereby fixing the position of the electric vehicle 10 when replacing the battery pack 101, which greatly improves the stability and reliability of the battery exchange station.

The vehicle positioning device includes a lifting mechanism 41, which is arranged below the electric vehicle 10 and is used to lift the electric vehicle 10 upward. The lifting mechanism 41 is arranged below the electric vehicle 10 and can move up and down. After the electric vehicle 10 is stably docked, when the battery pack 101 is replaced, the lifting mechanism 41 will rise upward and lift the electric vehicle 10 to a suitable height, so that the electric vehicle 10 will be against the force on the lifting mechanism 41, and the electric vehicle 10 will be positioned in the vertical direction through the lifting mechanism 41, and the electric vehicle 10 will be positioned as a rigid body, which effectively avoids the floating phenomenon of the electric vehicle 10 during the replacement of the battery pack 101, and greatly improves the stability and reliability of the battery swap station. After the replacement is completed, the lifting mechanism 41 will fall downward, so that the wheels of the electric vehicle 10 can touch the ground, and the electric vehicle 10 can drive out of the battery swap room 4. Among them, the unlocking mechanism can also be installed on the lifting mechanism 41, so that the unlocking mechanism is separated from the battery swap device to the lifting mechanism 41, the installation position is diversified, the installation is convenient, and the space utilization rate is high.

The vehicle positioning device includes a wheel positioning mechanism, which is arranged below the electric vehicle 10 and is used to align and position the wheels of the electric vehicle 10. When the electric vehicle 10 enters the battery swap room 4, the wheel positioning mechanism is used to guide and align the wheels of the electric vehicle 10, so that the wheels move along a preset route in the battery swap room 4. After the preset route is in place, the wheels of the electric vehicle 10 are clamped and positioned. The precise positioning of the electric vehicle 10 is achieved, which effectively avoids the horizontal displacement of the electric vehicle 10 and greatly improves the stability and reliability of the battery swap station.

A driving platform 42 is also provided in the battery exchange room 4, and the driving platform 42 is located below the charging room 5. The driving platform 42 is used for the electric vehicle 10 to drive in and out. When the electric vehicle 10 needs to change the battery, it will drive onto the driving platform 42, and the driving platform 42 will guide and position the electric vehicle 10.

Among them, the vehicle positioning device can be installed on the driving platform 42, making the battery swap room 4 very convenient to install and use, and easy to transport and maintain. Of course, the battery swap room 4 may also not include the driving platform 42, and the lifting mechanism 41 and the wheel positioning mechanism and other structures can be directly sunk into the underground foundation pit during the ground construction.

The charging room 5 includes a charging machine compartment 52 and a charging rack compartment 51. Both the charging machine compartment 52 and the charging rack compartment 51 are connected to the top of the battery exchange room 4. The charging rack compartment 51 is used to place the battery pack 101, and the charging machine compartment 52 is used to place the battery pack charger module. The charging rack compartment 51 and the charging machine compartment 52 are both arranged above the battery exchange room 4. The battery pick-up and placement mechanism 12 is lifted and moved to realize the pick-up and placement of the battery pack 101 on the charging rack compartment 51 and the electric vehicle 10. The battery pack charger module in the charging machine compartment 52 will charge the battery pack 101 in the charging rack compartment 51.

The battery exchange room 4 includes a warehouse support 43, the bottom end of which is used to be installed on the support surface, and the charging room 5 is connected to the top of the warehouse support 43. The bottom end of the warehouse support 43 can be installed on the driving platform 42 to realize the integrated design of the battery exchange room 4, which is very convenient to install and use, and easy to transport and maintain. Of course, the bottom end of the warehouse support 43 can also be installed on the ground.
