Description

Technical Field

[0001] This utility model relates to the field of battery swapping station technology, specifically a fully automated robotic battery swapping station. Background Technology

[0002] Electric vehicles require their electrical energy to be replenished in order to continue driving. Replenishment can be divided into two types: full vehicle charging and fast battery swapping. Battery swapping stations are energy stations that facilitate the rapid replacement of electric vehicle batteries. These stations typically have multiple swapping racks for charging, discharging, and maintaining the swapped batteries.

[0003] Currently, when existing battery swapping devices are placed in the swapping rack for charging and discharging, the batteries may experience thermal runaway due to overcharging, external damage, high-temperature environments, and inherent battery defects. Since the batteries experiencing thermal runaway are located inside the swapping rack, directly using a dry powder fire extinguisher to treat them will contaminate the surface of other batteries and the inside of the swapping rack, requiring subsequent treatment. At the same time, the surface temperature of the batteries will gradually rise during charging and discharging, necessitating cooling measures for the charging and discharging batteries. Utility Model Content

[0004] The purpose of this invention is to provide a fully automated robotic battery swapping station to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automated robot battery swapping station, comprising a base, two protective housings symmetrically mounted on the upper end of the base, each protective housing containing three battery swapping racks, a charging / discharging power module mounted on one side of each battery swapping rack, a battery swapping robot mounted between each of the three battery swapping racks, a battery swapping clamp mounted on each battery swapping robot, several battery swapping chambers sequentially mounted from top to bottom inside each battery swapping rack, a liquid cooling plate movably mounted inside each battery swapping chamber, a liquid cooling unit mounted on the upper end of the protective housing, a thermal runaway treatment chamber arranged below the lowest battery swapping chamber of one of the battery swapping racks, a limit component mounted at the front of the thermal runaway treatment chamber, and a treatment sandbox placed on one side of the thermal runaway treatment chamber.

[0006] Preferably, the three battery swapping racks are arranged in a U-shape, and the battery swapping robot is located between the three battery swapping racks.

[0007] Preferably, a support plate is installed on both sides of the inner wall of the battery swapping cavity, and a guide wheel is installed at equal intervals on the opposite surfaces of the two support plates. A base plate is installed at the bottom of the battery swapping cavity, and an inflatable airbag is installed at the upper end of the base plate. The liquid cooling plate is installed on the upper end of the inflatable airbag.

[0008] Preferably, the liquid cooling unit is equipped with a liquid cooling circulation pipe, and the liquid cooling circulation pipe is equipped with multiple branch pipes. The branch pipes are connected to the liquid cooling plate, and each branch pipe is equipped with a control valve.

[0009] Preferably, a driving passage is formed between the two protective enclosures, and a barrier gate is installed on both sides of the driving passage, with a security room located on one side of the barrier gate.

[0010] Preferably, the limiting component includes a mounting plate, a guide post, a spring, a lifting plate, a pressure block, and a limiting block. The mounting plate is installed at the front of the interior of the thermal runaway treatment chamber. A guide post is movably mounted above the mounting plate through a through hole. A lifting plate is installed at the upper end of the guide post. A spring is installed between the lifting plate and the mounting plate and outside the guide post. A pressure block is installed at the upper end of the lifting plate. A limiting block is installed at the upper end of the lifting plate behind the pressure block.

[0011] Preferably, the processing sandbox has a cavity inside, and U-shaped plates are installed inside the thermal runaway processing cavity and on both sides of the mounting plate and inside the cavity. Several guide wheels are installed in a linear array inside the U-shaped plates, and the U-shaped plates are arranged from high to low from one side to the other.

[0012] Preferably, one end of the treatment sandbox is provided with a passageway, and a baffle plate is rotatably installed inside the passageway via a rotating shaft. A top plate is placed on the upper end of the treatment sandbox, and a limit ring is installed at the lower end of the top plate. The limit ring is sleeved on the surface of the treatment sandbox.

[0013] Preferably, guide rods are installed on both sides of the lower end of the liquid cooling plate, and two sleeves are installed on the upper end of the base plate. The lower end of the guide rod passes through the inflatable airbag through a through hole and extends into the inside of the sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This fully automated robotic battery swapping station uses a robotic arm to place the battery that has experienced thermal runaway into the thermal runaway treatment chamber. The battery that has entered the thermal runaway treatment chamber then enters the treatment sandbox. After the treatment sandbox is moved, the battery that has experienced thermal runaway can be processed at a designated location, thus avoiding the impact on other batteries during fire suppression.

[0016] 2. This fully automated robot battery swapping station features a liftable liquid cooling plate installed inside the swapping chamber. This plate cools the batteries during charging and discharging, effectively preventing excessive surface temperature. The lifting design also prevents contact between the liquid cooling plate and the batteries during insertion and removal, thus avoiding scratches and extending the plate's lifespan. Furthermore, each liquid cooling plate can be individually controlled, cooling only the batteries during charging and discharging, effectively reducing the energy consumption of the liquid cooling unit.

[0017] 3. This fully automated robot battery swapping station uses a limiting component installed inside the heat treatment chamber. In its natural state, the elastic spring generates elastic force to support the lifting plate, and the limiting block on the lifting plate blocks the thermal runaway treatment chamber, preventing the swapped battery from accidentally entering the thermal runaway treatment chamber due to accidental operation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] like Figures 1 to 7As shown, this embodiment of the fully automated robot battery swapping station includes a base 1, which is made of cast concrete. Two protective housings 2 are symmetrically installed on the upper part of the base 1. These protective housings 2 are used to protect the battery swapping racks 3. The protective housings 2 are container-like structures with a certain degree of airtightness. Three battery swapping racks 3 are placed inside each protective housing 2. A charging / discharging power module 4 is installed on one side of each battery swapping rack 3. The charging / discharging power module 4 is used to charge and discharge the swapped batteries. A battery swapping robot 5 is installed between each of the three battery swapping racks 3. The battery swapping robot 5 is a robotic arm that operates according to a specific battery swapping program. A battery swapping gripper 6 is installed on the battery swapping robot 5. The gripper 6 picks up and places the swapped batteries. Several battery swapping chambers 7 are installed sequentially from top to bottom inside each battery swapping rack 3. The battery swapping chambers 7 are used to place the swapped batteries. A liquid cooling plate 8 is movably installed inside each battery swapping chamber 7. It can contact the bottom of the battery for easy cooling during charging and discharging. A liquid cooling unit 9 is installed on the upper part of the protective box 2. The liquid cooling unit 9 is used to supply the liquid cooling plate 8 for cooling and heat absorption. The specific working principle of the liquid cooling unit 9 is known existing technology, so it will not be described in detail. A thermal runaway treatment chamber 10 is arranged below the battery swapping chamber 7 at the bottom of the battery swapping rack 3. The thermal runaway treatment chamber 10 is used to place the battery that has experienced thermal runaway. A limiting component is installed at the front of the thermal runaway treatment chamber 10 to block and limit the thermal runaway treatment chamber 10, preventing the battery from being directly placed into the thermal runaway treatment chamber 10. A treatment sandbox 12 is placed on one side of the thermal runaway treatment chamber 10. The treatment sandbox 12 is used to move and transfer the battery that has experienced thermal runaway, so as to facilitate fire treatment of the battery that has experienced thermal runaway in a suitable location.

[0029] Specifically, the three battery swapping racks 3 are arranged in a U-shape, and the battery swapping robot 5 is located between the three battery swapping racks 3. One battery swapping robot 5 can take the batteries from the three battery swapping racks 3, effectively reducing the number of battery swapping robots 5 required.

[0030] Furthermore, support plates 13 are installed on both sides of the inner wall of the battery swapping chamber 7. Guide wheels 14 are installed at equal intervals on the opposite surfaces of the two support plates 13. When the battery is placed into the battery swapping chamber 7, the battery contacts the guide wheels 14, which facilitates the placement and removal of the battery from the battery swapping chamber 7. A base plate 15 is installed at the bottom of the battery swapping chamber 7. An inflatable airbag 16 is installed on the upper end of the base plate 15. A liquid cooling plate 8 is installed on the upper end of the inflatable airbag 16. The inflatable airbag 16 is inflated by an inflation device, and the expansion of the inflatable airbag 16 causes the liquid cooling plate 8 to rise. The liquid cooling plate 8 contacts the bottom of the battery swapping chamber 7. When the battery swapping chamber 7 is placed into and removed from the battery swapping chamber 7, the liquid cooling plate 8 does not contact the battery swapping chamber 7, thus avoiding scratches on the surface of the liquid cooling plate 8 when the battery swapping chamber 7 moves.

[0031] Furthermore, the liquid cooling unit 9 is equipped with a liquid cooling circulation pipe 17, which has multiple branch pipes 18 connected to the liquid cooling plate 8. Each branch pipe 18 is equipped with a control valve 19. The liquid cooling unit 9 circulates the heat exchange medium into the liquid cooling plate 8 through the liquid cooling circulation pipe 17 and the branch pipes 18 to cool the battery. The control valves 19 can control the branch pipes 18 to cool only the battery that is being charged or discharged. This allows for individual control of the multiple liquid cooling plates 8, effectively reducing the energy consumption of the liquid cooling unit 9.

[0032] Furthermore, a driving channel 20 is formed between the two protective boxes 2. Barrier gates 21 are installed on both sides of the driving channel 20. A security room 22 is set on one side of the barrier gate 21. The barrier gate 21 is used to control the number of battery swapping vehicles entering the battery swapping station.

[0033] Furthermore, the limiting assembly includes a mounting plate 1101, a guide post 1102, a spring 1103, a lifting plate 1104, a pressure block 1105, and a limiting block 1106. The mounting plate 1101 is installed at the front of the thermal runaway treatment chamber 10. A guide post 1102 is movably mounted above the mounting plate 1101 through a through hole. A lifting plate 1104 is installed at the upper end of the guide post 1102. A spring 1103 is installed between the lifting plate 1104 and the mounting plate 1101, located outside the guide post 1102. A pressure block 1105 is installed at the upper end of the lifting plate 1104. A limiting block 1106 is installed at the upper end of the lifting plate 1104 behind the pressure block 1105. In its natural state... The elastic spring 1103 generates elastic force to support the lifting plate 1104. The limiting block 1106 on the lifting plate 1104 blocks the thermal runaway treatment cavity 10 to prevent other batteries from accidentally entering the thermal runaway treatment cavity 10. When it is necessary to put the battery that has caused thermal runaway into the thermal runaway treatment cavity 10, the battery swapping robot 5 presses the pressure block 1105 through the battery swapping clamp 6. The pressure block 1105 drives the lifting plate 1104 and the limiting block 1106 to move down. At the same time, the lifting plate 1104 drives the guide column 1102 to move down and presses the elastic spring 1103, so that the limiting block 1106 does not limit the thermal runaway treatment cavity 10, and the battery that has caused thermal runaway can be put in normally.

[0034] Furthermore, the processing sandbox 12 is equipped with a cavity 23. U-shaped plates 24 are installed inside the thermal runaway processing cavity 10 and on both sides of the mounting plate 1101 and the cavity 23. Several guide wheels 25 are installed in a linear array inside the U-shaped plates 24. The U-shaped plates 24 are arranged from high to low from one side to the other. The setting of the guide wheels 25 effectively reduces the friction between the battery that has caused thermal runaway and the U-shaped plate 24 when it moves. Moreover, there is no need to push the battery that has caused thermal runaway. The battery can automatically enter the processing sandbox 12 through the thermal runaway processing cavity 10.

[0035] Furthermore, one end of the treatment sand box 12 is provided with a passage opening. Inside the passage opening, a baffle plate 30 is rotatably installed via a rotating shaft. The baffle plate 30 is used to block the passage opening and plays a protective role. A top plate 26 is placed on the upper end of the treatment sand box 12. A limit ring 27 is installed at the lower end of the top plate 26. The limit ring 27 is sleeved on the surface of the treatment sand box 12, so that the top plate 26 can be removed from the treatment sand box 12, which facilitates the use of fire-fighting sand to bury the battery inside the treatment sand box 12.

[0036] Furthermore, guide rods 28 are installed on both sides of the lower end of the liquid cooling plate 8, and two sleeves 29 are installed on the upper end of the base plate 15. The lower end of the guide rod 28 passes through the inflatable airbag 16 through the through hole and extends into the inside of the sleeve 29. The sleeve 29 and the guide rod 28 play a guiding role in the lifting and lowering of the liquid cooling plate 8, which facilitates the vertical lifting and lowering of the liquid cooling plate 8.

[0037] The usage method of this embodiment is as follows: When the battery swapping vehicle enters the driving channel 20 through the barrier gate 21 and drives to the designated position for battery swapping, the battery swapping robot 5 uses the battery swapping clamp 6 to move the battery of the battery swapping vehicle into the empty battery swapping cavity 7. Then, the battery that has been charged and discharged is installed inside the battery swapping vehicle. When the battery needs to be charged and discharged, the inflation device inflates the inflation bag 16. The inflation bag 16 expands and drives the liquid cooling plate 8 to rise. The liquid cooling plate 8 comes into contact with the battery, and the liquid cooling unit 9 discharges the heat exchange medium into the liquid cooling plate 8 for heat exchange. During this process, the control valve 19 on the corresponding branch pipe 18 opens, allowing the heat exchange medium to enter the corresponding liquid cooling plate 8, realizing individual control of each liquid cooling plate 8. When the battery is fully charged and discharged, the liquid cooling plate 8 stops cooling, and the corresponding control valve 19 closes, and the inflation device stops charging and discharging. When the bladder 16 is deflated, the liquid cooling plate 8 descends and does not contact the battery. When the battery experiences thermal runaway, the battery swapping robot 5 uses the battery swapping clamp 6 to move the battery that has experienced thermal runaway. The battery swapping clamp 6 is moved to one side of the thermal runaway treatment chamber 10, and the clamp 6 is used to press the pressure block 1105. The pressure block 1105 moves the lifting plate 1104 and the limiting block 1106 downward. At the same time, the lifting plate 1104 moves the guide column 1102 downward and presses the spring spring 1103, so that the limiting block 1106 does not limit the thermal runaway treatment chamber 10. The battery that has experienced thermal runaway is placed on the U-shaped plate 24 and contacts the guide wheel 25. Under the action of gravity, the battery that has experienced thermal runaway enters the treatment sandbox 12 through the thermal runaway treatment chamber 10. After the treatment sandbox 12 is moved to a suitable position, the top plate 26 is removed, and the battery can be sprayed with dry powder fire extinguisher or buried with fire sand.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
