In order to describe the present invention in detail, the application environment of the present invention is first described in detail:

For electric vehicles, the slow charging speed affects the travel and use of electric vehicles, and directly replacing the battery of electric vehicles is a technical way to solve the slow charging speed of electric vehicles. As an emerging product, the public has a low level of understanding of electric vehicles. Therefore, many automobile manufacturers often invite the public to visit the production, after-sales, and maintenance of electric vehicles to increase the understanding and cognition of new products and new technologies from all walks of life, so as to obtain more resource investment. As a technical way to solve the slow charging speed of electric vehicles, the battery replacement of electric vehicles is also often used in the display scene. However, in the field of electric vehicle production, the actual battery replacement station has high investment cost, long cycle, and large area. It is difficult to build and put into use in a short time, which is not enough to meet the exhibition needs of enterprises.

In view of the above situation, in some embodiments, a car battery replacement demonstration method is provided, please refer to Figures 1 to 6, a demonstration battery replacement station is used to replace the battery of a car model 6, the demonstration battery replacement station includes a battery warehouse 5, a battery replacement device 3 and a robot 4, the battery 2 warehouse is used to store batteries 2, and the battery replacement device 3 is provided with a battery placement position 1.

Please refer to FIG. 7 , the battery replacement demonstration method includes the following steps:

S10: Place the car model 6 to be replaced with battery in the battery replacement device 3.

S20: The battery replacement device 3 removes the battery 2 to be replaced from the car model 6.

S30 : The robot 4 transports the removed battery 2 from the battery placement position 1 of the battery replacement device to the battery warehouse 5 , and transports the battery 2 for replacement from the battery warehouse 5 to the battery placement position 1 of the battery replacement device 3 .

S40 : The battery replacement device 3 installs the battery 2 for replacement into the car model 6 .

The demonstration battery swap station is used to swap the battery of the car model to demonstrate the battery swap process of the electric vehicle. Compared with the actual vehicle battery swap station, it has the advantages of simple structure, low cost, short development cycle, small space occupation, easy layout, etc., and is suitable for demonstration use. At the same time, the demonstration battery swap station uses a robot 4 to carry the battery 2, and the battery warehouse 5 and the battery placement position 1 are all moved within the handling range of the robot 4, which is convenient for visitors to observe, visual and intuitive, and conducive to visitors' understanding.

As shown in Fig. 2 to Fig. 6, in one embodiment, the battery replacement device 3 includes a first bracket 8, a clamping assembly 7 and a disassembly assembly 10. The clamping assembly 7 is arranged above the first bracket 8, and the disassembly assembly 10 is arranged below the first bracket 8. The first bracket 8 is provided with an opening matching the size of the battery 2. The clamping assembly 7 is used to clamp the car model 6, and the disassembly assembly 10 is used to disassemble and assemble the battery 2 of the car model 6. The first bracket 8 supports the clamping assembly 7 and the disassembly assembly 10.

When the car model 6 is clamped on the clamping assembly 7, the position of the car model 6 is fixed, which facilitates the disassembly assembly 10 to align with the battery 2. In some embodiments, the clamping assembly 7 includes a pressure head and a positioning structure, the positioning structure positions the car model 6, and the pressure head fixes the car model 6 to prevent the car model 6 from moving when the disassembly assembly 10 disassembles and assembles the battery 2.

After step S10, that is, after the car model is placed in the battery replacement device 3, the clamping assembly 7 positions the car model 6, and the battery 2 to be replaced is aligned with the opening on the first bracket 8. After the clamping assembly 7 positions the car model 6, the disassembly assembly 10 removes the battery 2 to be replaced in the car model 6, and installs the battery 2 for replacement into the car model 6.

Since the disassembly and assembly component 10 is arranged below the clamping component 7, when the disassembly and assembly component 7 removes the battery 2 to be replaced from the car model 6, the removed battery 2 can move downward under the action of gravity without providing additional power, which is conducive to simplifying the structure of the disassembly and assembly component.

Due to the spacing between the battery placement position 1 and the disassembly assembly 10, the space around the battery placement position 1 is large, which increases the spacing between the robot 4 and the disassembly assembly 10 when the robot 4 takes and places the battery to the battery placement position 1, which is conducive to avoiding interference between the robot 4 and the disassembly assembly 10, and facilitating the taking and placing of the battery. In this embodiment, a positioning structure is provided on the battery placement position 1. When the battery 2 is on the battery placement position 1, the positioning structure constrains the position of the battery, which is convenient for the robot 4 to grasp.

In some embodiments, the battery replacement device 3 further includes a second bracket 11, which is lower than the first bracket 8, and the battery placement position 1 is disposed on the second bracket 11. The second bracket 11 raises the height of the battery placement position 11, so that the battery placement position 11 and the disassembly assembly 10 are close in height.

In some embodiments, the disassembly and assembly component 10 includes a locking mechanism and a supporting mechanism. The locking mechanism is arranged around the supporting mechanism. When the disassembly and assembly component 10 disassembles the battery 2 to be replaced from the car model 6, the locking mechanism unlocks the connection between the battery 2 and the car model 6; when the disassembly and assembly component 10 installs the battery 2 to be replaced into the car model 6, the locking mechanism locks the battery 2 to the car model 6.

Specifically, the locking mechanism includes a locking head 14 , and the lifting mechanism includes a lifting rod 15 . The locking head 14 and the lifting rod 15 are respectively arranged on the lifting unit 13 , and the locking head 14 and the lifting rod 15 can be lifted and lowered respectively under the action of the lifting unit 13 .

Step S20, i.e., the step of disassembling the battery 2 to be replaced of the automobile model 6 by the disassembling assembly 10, includes the following steps:

The lifting unit 13 pushes the locking head 14 and the lifting rod 15 to rise respectively. After the locking head 14 unlocks the connection between the battery 2 and the car model 6 , the lifting rod 15 lifts the battery 2 and descends under the action of the lifting unit 13 .

Step S40, i.e. the step in which the disassembly assembly 10 installs the battery 2 for replacement into the car model 6, includes the following steps:

The lifting unit 13 pushes the locking head 14 and the lifting rod 15 to rise respectively, and after the lifting rod 15 pushes the battery 2 to be replaced into the car model 6, the locking head 14 locks the connection between the battery 2 and the car model 6. In this embodiment, the battery 2 and the car model 6 are connected by screws, and the locking head 14 locks the battery 2 on the car model 6 by screws.

In some embodiments, the transfer assembly is two conveyor belts 9 arranged in parallel, and the top supporting rod 15 is spatially arranged in the middle of the two conveyor belts 9 arranged in parallel.

In step S20, that is, the step of disassembling the battery 2 to be replaced of the automobile model 6 by the disassembly assembly 10, the following steps are included: the battery 2 to be replaced is lowered along the supporting rod 15 until the battery 2 to be replaced stops on the two conveyor belts 9, and the conveyor belts 9 move the battery 2 to be replaced to the battery placement position 1.

In step S40, that is, the step in which the disassembly and assembly component 10 installs the battery 2 for replacement into the car model 6, the following steps are included: the conveyor belt 9 moves the battery 2 for replacement to above the supporting rod 15, and the supporting rod 15 rises to support the battery 2 for replacement until it enters the car model 6.

The top supporting rod 15 of the top supporting mechanism has an upper limit and a lower limit under the action of the lifting unit 13. The position of the conveyor belt 9 is between the upper limit and the lower limit of the top supporting rod 15.

Specifically, as shown in FIG6 , when the disassembly assembly 10 removes the battery 2 unit from the car model 6, the lifting rod 15 first moves to the upper limit to hold the battery 2. Then the locking head 14 rises, aligns with the connection position between the battery 2 and the car model 6, and cancels the connection between the battery 2 and the car model 6. The lifting rod 15 is lowered by the lifting unit 13, and the battery 2 on the lifting rod 15 moves with the lifting rod 15 under the action of gravity until the lifting rod 15 is lower than the position of the conveyor belt 9, and the battery 2 stays on the conveyor belt 9, completing the removal of the battery 2.

When the battery 2 is transported to the lifting mechanism by the conveyor belt 9, it is aligned with the lifting rod 15, and the lifting rod 15 rises under the action of the lifting unit 13, lifting the battery 2 from the conveyor belt 9. At this time, the car model 6 is clamped on the clamping assembly 7, and the lifting rod 15 continues to rise until the upper limit. At this time, the battery 2 enters the battery compartment of the car model 6 under the action of the lifting rod 15. The locking head 14 rises under the action of its lifting unit 13, aligns with the connection position of the battery 2 and the car model 6, and fixes the battery 2 in the car model 6.

In some embodiments, the battery 2 and the car model 6 are provided with mutually cooperating positioning structures. When the battery 2 enters the battery 2 compartment, the positioning structure positions the battery 2 and the car model 6 to ensure that the battery 2 is aligned with the car model 6, making it easier for the locking assembly to lock the battery 2 on the car model 6 and complete the installation of the battery 2.

In this embodiment, the lifting unit 13 is a cylinder, which is small in size and sensitive in response, and the medium can be air, which is pollution-free and suitable for demonstration. The battery 2 and the car model 6 are connected by screws, and the locking head 14 is a screw gun for removing and installing screws.

In some embodiments, the battery warehouse 5 includes a storage position, and a restraining mechanism for restraining the position of the battery is provided on the storage position. The battery 2 in the battery warehouse 5 is fixedly stored in the storage position by the restraining mechanism, and the restraining mechanism restrains the position of the battery 2 to facilitate the grasping of the robot 4. A charging device is provided in the battery warehouse 5 to charge the battery 2 in the battery warehouse 5.

Specifically, the restraining mechanism may be a positioning groove, the shape of which matches the shape of the battery 2, so as to constrain and position the battery 2 placed therein. A spring for electrical connection may be provided in the positioning groove, and when the battery 2 is placed in the positioning groove, the battery 2 is connected to the battery warehouse 5, and the battery warehouse 5 can charge the battery 2 through the spring.

As shown in FIG. 1 , in some embodiments, the robot 4 is a robotic arm. When the car model 6 needs to be replaced, the battery replacement device 3 removes the battery 2 from the car model 6 and places it on the battery placement position 1. The robotic arm grabs the replaced battery 2 from the battery placement position 1 and transfers it to the battery warehouse 5. Then the robotic arm grabs the battery 2 from the battery warehouse 5 and transfers it to the battery placement position 1. The battery 2 is installed in the car model 6 by the battery replacement device 3 to complete the replacement of the battery 2. The battery placement position 1 and the battery warehouse 5 are both fixedly set, and their position information can be preset in the robotic arm to facilitate the robotic arm to grab and place.

In some embodiments, the robot 4 is provided with an image acquisition device, and step S30 includes the following steps:

The image information of the battery 2 on the battery placement position 1 is obtained by an image acquisition device.

Analyze the image information, obtain the position information of the battery 2 and determine whether to perform position correction.

The moving path of the robot 4 is planned according to the preset location information of the battery warehouse 5 and the location information of the battery 2 to complete the transportation of the battery 2 to the battery warehouse 5 .

Among them, the position of the battery warehouse 5 is usually fixed, and its position information can be obtained and set in advance. At the same time, after the robot arm obtains the image information of the battery 2 through the image acquisition device, the image information of the battery 2 can be analyzed to obtain the real-time position information of the battery 2. Compared with directly pre-setting the position information of the battery 2, the position information of the battery 2 obtained by analyzing the image information of the battery 2 has higher accuracy, and the running trajectory of the robot arm can be corrected to improve the grasping accuracy of the robot arm.

In some embodiments, before acquiring the image information of the battery 2 by the image acquisition device, the following steps are included:

Preset battery 2 position information, and then determine the collection position according to the preset battery 2 position information and the mapping relationship between the preset battery 2 position information and the collection position;

The robot 4 moves to the acquisition position and obtains the image information of the battery 2 through the image acquisition device. The robot 4 first moves to the acquisition position and then acquires the image information of the battery 2, which is conducive to improving the acquisition quality of the image. At the same time, the acquisition position is obtained according to the preset battery 2 position information and the mapping relationship between the preset battery 2 position information and the acquisition position. When the preset battery 2 position information is changed, the acquisition position is also changed accordingly. There is no need to additionally acquire and process external information, which reduces the operation of the robot 4 and is conducive to increasing the reaction speed of the robot 4.

In some embodiments, the demonstration battery swap station further includes a display screen, which is used to display battery swap progress information and battery 2 information in the battery warehouse 5. The display screen is intuitive and convenient for visitors to observe, which helps visitors understand the role of image acquisition and deepen their understanding of automobile production.

In summary, the present embodiment provides a method for demonstrating battery replacement of a car, which uses a demonstration battery replacement station to replace the battery of a car model, and is used to demonstrate the battery replacement process of an electric car. Compared with the actual vehicle battery replacement station, the demonstration battery replacement station has a simple structure, low cost, short development cycle, small space occupation, easy layout, and is suitable for demonstration use. At the same time, robots are used to transport batteries, and the battery warehouse and battery placement position are all moved within the robot's handling range, which is convenient for visitors to observe, visually intuitive, and conducive to visitors' understanding.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention.
