Description

Technical Field

[0001] This utility model relates to the field of battery swapping station technology, specifically a multi-functional battery swapping station. Background Technology

[0002] Electric vehicles require their electrical energy to be replenished in order to continue driving. The existing ways to replenish electrical energy can be divided into two types: vehicle charging and battery swapping. Battery swapping stations are energy stations that provide rapid replacement of the power batteries of electric vehicles. Battery swapping stations are usually equipped with multiple battery swapping racks.

[0003] Currently, when existing battery swapping stations are in use, multiple batteries are placed inside the swapping rack for charging and discharging. During charging, the surface of the batteries generates heat. Excessive heat or damage to the surface of some batteries can cause thermal runaway. It is necessary to deal with the batteries that have thermal runaway in a timely manner and cool down the swapping station appropriately. Based on this, a multifunctional battery swapping station that solves the above problems is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a multifunctional battery swapping station to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional battery swapping station, including a base, with protective boxes placed on both sides of the upper end of the base, forming a passageway between two protective boxes, and three battery swapping racks placed inside each protective box. The three battery swapping racks are arranged in a U-shape, and a robotic arm is installed between the three battery swapping racks. A battery swapping clamp is installed on the robotic arm, and several battery swapping chambers are arranged at the front end of each battery swapping rack. A liquid cooling plate is movably installed inside each battery swapping chamber. A liquid cooling unit is installed above both protective boxes, and a thermal runaway treatment chamber is arranged at the front end of each battery swapping rack below the lowest battery swapping chamber on both sides.

[0006] Preferably, a barrier gate is installed on both sides of the passageway, and a security room is set up on one side of each barrier gate.

[0007] Preferably, each of the battery swapping chambers is equipped with a base plate at its bottom, and an inflatable airbag is installed at the top of each base plate, with the liquid cooling plate located at the top of the inflatable airbag.

[0008] Preferably, guide sleeves are installed on both sides of the upper end of the base plate, and two guide rods are installed on both sides of the lower end of the liquid cooling plate. The guide rods pass through the inflatable airbag through through holes and are located inside the guide sleeves.

[0009] Preferably, the thermal runaway treatment chamber is a through-type structure, a treatment sandbox is placed at the rear of the thermal runaway treatment chamber, a cavity is provided inside the treatment sandbox, and a protective plate is rotatably installed at the front end of the treatment sandbox in front of the cavity.

[0010] Preferably, the thermal runaway treatment chamber and the bottom of the chamber are each equipped with two support plates, and the upper end of the support plates is equipped with a number of rotating wheels in a linear array.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This multi-functional battery swapping station has a thermal runaway treatment chamber set on the battery swapping rack. Batteries that have experienced thermal runaway are placed inside the thermal runaway treatment chamber for further processing, thus preventing the batteries that have experienced thermal runaway from affecting the remaining batteries.

[0013] 2. This multi-functional battery swapping station features a liftable liquid cooling plate installed inside the battery swapping chamber of the swapping rack. When the battery is inserted, it does not come into contact with the liquid cooling plate. After the battery is inserted, the liquid cooling plate rises and contacts the bottom of the swapping box. The liquid cooling plate can cool the battery during charging and discharging. At the same time, the liquid cooling plate does not come into contact with the battery when it is inserted and removed, thus avoiding scratches on the surface of the liquid cooling plate.

[0019] 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.

[0021] like Figures 1 to 4 As shown, this embodiment of the multi-functional battery swapping station includes a base 1, which is made of cast concrete. Protective boxes 2, which are container-like structures, are placed on both sides of the upper part of the base 1 to provide overall protection for the battery swapping racks 4. A passageway 3 is formed between the two protective boxes 2, allowing vehicles requiring battery swapping to travel. Each protective box 2 contains three battery swapping racks 4 arranged in a U-shape. A robotic arm 5 is installed between the three battery swapping racks 4. One robotic arm 5 can pick up and place the batteries on the three battery swapping racks 4. The robotic arm 5 is equipped with a battery swapping clamp 6, which is used to hold the swapping battery. The front end of the battery swapping rack 4 is provided with several battery swapping chambers 7. Liquid cooling plates 8 are movably installed inside the battery swapping chambers 7. Liquid cooling units 9 are installed on top of the two protective boxes 2. The liquid cooling plates 8 and liquid cooling units 9 are connected. The liquid cooling plates 8 can cool the charging and discharging batteries. Thermal runaway treatment chambers 10 are provided at the front end of the battery swapping rack 4 below the bottom battery swapping chamber 7 on both sides. Thermal runaway treatment chambers 10 are used to treat batteries that have thermal runaway, so as to prevent the batteries that have thermal runaway from affecting the remaining swapping batteries.

[0022] Specifically, a barrier gate 11 is installed on both sides of the passageway 3. The barrier gate 11 is used to block the battery swapping vehicle and ensure that there is only one battery swapping vehicle between the two barrier gates 11. A security room 12 is set up on one side of each barrier gate 11.

[0023] Furthermore, each battery swapping chamber 7 is equipped with a base plate 13 at its bottom, and an inflatable airbag 14 is installed on the top of the base plate 13. The liquid cooling plate 8 is located on the top of the inflatable airbag 14. The inflatable airbag 14 is inflated by an inflation device. The expansion of the inflatable airbag 14 causes the liquid cooling plate 8 to rise and contact the bottom of the battery swapping chamber, thereby cooling the battery swapping chamber. The liquid cooling plate 8 only contacts the battery box after the battery is placed, to avoid scratching the liquid cooling plate 8 when the battery is inserted and removed.

[0024] Furthermore, guide sleeves 15 are installed on both sides of the upper end of the base plate 13, and two guide rods 16 are installed on both sides of the lower end of the liquid cooling plate 8. The guide rods 16 pass through the inflatable airbag 14 through the through hole and are located inside the guide sleeves 15. When the liquid cooling plate 8 rises and falls, the guide rods 16 slide inside the guide sleeves 15 to guide the liquid cooling plate 8 to rise and fall.

[0025] Furthermore, the thermal runaway treatment chamber 10 is a through-type structure, and a treatment sandbox 21 is placed at the rear of the thermal runaway treatment chamber 10. The treatment sandbox 21 has a cavity 17 inside, and a protective plate 18 is rotatably installed at the front end of the treatment sandbox 21 in front of the cavity 17. The battery swapping device placed inside the thermal runaway treatment chamber 10 will move into the cavity 17 inside the treatment sandbox 21. The protective plate 18 is used to ensure the overall protection of the thermal runaway battery by the treatment sandbox 21 and the insertion and removal of the battery swapping device.

[0026] Furthermore, both the thermal runaway treatment chamber 10 and the chamber 17 have two support plates 19 installed at their bottom ends. Several rotating wheels 20 are mounted on the upper end of the support plates 19 in a linear array. The rotating wheels 20 are in contact with the battery swapping device, which facilitates the battery swapping device that has caused thermal runaway to slide into the treatment sandbox 21.

[0027] The usage method of this embodiment is as follows: During use, the battery swapping vehicle enters between the two protective boxes 2 through the barrier gate 11. The robotic arm 5 uses the battery swapping clamp 6 to move the battery swapping device, remove the battery swapping device from the vehicle, and place it into the battery swapping chamber 7. The robotic arm 5 installs the battery swapping device inside the vehicle after charging. Then, the inflation device inflates the inflation airbag 14. The inflation airbag 14 expands and drives the liquid cooling plate 8 to rise. The liquid cooling plate 8 contacts the bottom of the battery swapping device, and the liquid cooling device cools the battery swapping box through the liquid cooling plate 8. When the battery experiences thermal runaway, the robotic arm 5 uses the battery swapping clamp 6 to remove the battery swapping device that has experienced thermal runaway from the battery swapping chamber 7. Then, the battery that has experienced thermal runaway is placed into the thermal runaway treatment chamber 10 and slides into the treatment sand box 21 through the rotating wheel 20 on the support plate 19. The treatment sand box 21 is used to transfer the battery swapping device that has experienced thermal runaway to another location to avoid affecting the remaining batteries.

[0028] 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.
