Technical Field

[0001] This utility model relates to the field of charging rack technology, specifically a battery swapping station charging rack with a battery thermal runaway handling channel. Background Technology

[0002] New energy vehicles are generally powered by charging. However, due to issues such as long charging times and uneven distribution of charging stations, new energy vehicle users still face range anxiety and charging anxiety. Battery swapping, as a more efficient way to replenish energy, has many advantages. A battery swapping station is an energy station that centrally stores and charges batteries. It provides battery replacement services for electric vehicles by simply swapping a fully charged battery from the charging rack into the car to meet driving needs.

[0003] Currently, battery thermal runaway refers to the uncontrolled chemical reaction process inside the battery, which leads to an increase in battery temperature and may cause dangerous situations such as fire and explosion. Overcharging or discharging of the battery or puncture damage can cause thermal runaway. The existing treatment method is generally to use a dry powder fire extinguisher to treat the battery. The thermal runaway battery is located inside the charging rack, and the treatment will contaminate the external surface of the other batteries in the charging rack, affecting the normal use of other battery boxes and causing inconvenience. Utility Model Content

[0004] The purpose of this invention is to provide a battery swapping station charging rack with a battery thermal runaway handling channel to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery swapping station charging rack with a battery thermal runaway treatment channel, comprising a charging rack body, wherein a plurality of battery placement cavities are arranged sequentially from top to bottom at the front end of the charging rack body, and a thermal runaway treatment cavity is arranged through the front end of the charging rack body below the lowest battery placement cavity, wherein guide plates are installed on both sides inside the thermal runaway treatment cavity, and two support plates are installed at the bottom end of the thermal runaway treatment cavity between two guide plates, wherein a limiting component is installed between the two support plates, and a treatment sandbox is placed at the rear of the thermal runaway treatment cavity.

[0006] Preferably, the upper end of the support plate is provided with a plurality of mounting slots arranged sequentially from back to front, and each mounting slot is rotatably mounted with a guide wheel through a rotating shaft, and the surface of each guide wheel extends to the outside of the mounting slot.

[0007] 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 between the two support plates and in front 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.

[0008] Preferably, side plates are installed on both sides of the battery placement cavity, and a number of guide wheels are installed on the opposite surfaces of the two side plates from back to front. A charging and discharging connector is installed at the rear end of the battery placement cavity.

[0009] Preferably, a liquid cooling plate is installed at the bottom of the battery placement cavity.

[0010] Preferably, the upper end of the support plate is inclined from high to low from front to back.

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

[0012] 1. This battery swapping station charging rack with a battery thermal runaway handling channel has a thermal runaway handling chamber set on the charging rack. When a new energy battery experiences thermal runaway, the battery that has experienced thermal runaway slides into the handling sandbox through a support plate. The handling sandbox can move the battery that has experienced thermal runaway to the outside of the charging rack for handling, so as to avoid affecting the other batteries.

[0013] 2. This battery swapping station charging rack with a battery thermal runaway treatment channel is equipped with a limiting component. The elastic spring in the limiting component generates elastic force so that the height of the pressure block and the limiting block on the lifting plate is higher than the support plate. When the lifting plate is not pressed, the new energy battery box cannot be put into the thermal runaway treatment chamber, thus avoiding the possibility of putting a good new energy battery into the thermal runaway treatment chamber due to operational errors during battery swapping.

[0021] like Figures 1 to 4 As shown, the battery swapping station charging rack with a battery thermal runaway handling channel in this embodiment includes a charging rack body 1. Several battery placement cavities 2 are arranged sequentially from top to bottom at the front end of the charging rack body 1. The battery placement cavities 2 are used to place new energy batteries. A thermal runaway handling cavity 3 is arranged through the front end of the charging rack body 1 below the lowest battery placement cavity 2. The thermal runaway handling cavity 3 is used to place new energy batteries that have experienced thermal runaway. Guide plates 4 are installed on both sides inside the thermal runaway handling cavity 3. The guide plates 4 are used to guide the batteries placed inside the thermal runaway handling cavity 3. Two support plates 5 are installed at the bottom of the thermal runaway handling cavity 3 between the two guide plates 4. The support plates 5 are used to support the new energy batteries that have experienced thermal runaway. A limiting component is installed between the two support plates 5. The limiting component limits the thermal runaway handling cavity 3 to prevent battery swapping personnel from accidentally placing intact new energy batteries into the thermal runaway handling cavity 3. A processing sandbox 7 is placed at the rear of the thermal runaway handling cavity 3. The processing sandbox 7 is used to receive the new energy batteries that have experienced thermal runaway.

[0022] Specifically, the upper end of the support plate 5 is provided with several mounting slots 8 arranged from back to front. Inside each mounting slot 8, a guide wheel 9 is rotatably mounted via a rotating shaft. The surface of the guide wheel 9 extends to the outside of the mounting slot 8. The setting of the guide wheel 9 facilitates the sliding of the thermally runaway new energy battery on the support plate 5 into the processing sandbox 7.

[0023] Furthermore, the limiting assembly includes a mounting plate 601, a guide post 602, a spring spring 603, a lifting plate 604, a pressure block 605, and a limiting block 606. The mounting plate 601 is installed between the two support plates 5 and in front of the thermal runaway treatment chamber 3. A guide post 602 is movably mounted above the mounting plate 601 through a through hole. A lifting plate 604 is installed at the upper end of the guide post 602. A spring spring 603 is installed between the lifting plate 604 and the mounting plate 601 and outside the guide post 602. A pressure block 605 is installed on the upper end of the lifting plate 604, and a limit block 606 is installed on the upper end of the lifting plate 604 behind the pressure block 605. In the natural state, the elastic spring 603 generates elastic force so that the height of the pressure block 605 and the limit block 606 on the lifting plate 604 is higher than that of the support plate 5. When the lifting plate 604 is not pressed, the new energy battery box cannot be put into the thermal runaway treatment chamber 3, so as to avoid putting the intact new energy battery into the thermal runaway treatment chamber 3 due to operational errors during the battery swapping operation.

[0024] Furthermore, side plates 10 are installed on both sides inside the battery placement cavity 2. Several guide wheels 11 are installed on the opposite surfaces of the two side plates 10 from back to front. The guide wheels 11 are used to support the new energy battery box. A charging and discharging connector 12 is installed at the rear end inside the battery placement cavity 2. The charging and discharging connector 12 is used to connect with the new energy battery box to realize the charging and discharging of the new energy battery box.

[0025] Furthermore, a liquid cooling plate 13 is installed at the bottom of the battery placement cavity 2. The liquid cooling plate 13 is connected to the liquid cooling equipment on the charging rack. The liquid cooling plate 13 is in contact with the bottom of the battery placed inside the battery placement cavity 2 to prevent the surface temperature of the battery box from being too high during charging and discharging.

[0026] Furthermore, the upper part of the support plate 5 is arranged at an angle from high to low from front to back, so that the new energy battery placed inside the thermal runaway treatment chamber 3 can slide into the treatment sandbox 7 on its own without the need for external force.

[0027] The usage method of this embodiment is as follows: In daily use, the new energy battery is placed inside the battery placement cavity 2 and connected to the charging and discharging connector 12. The charging and discharging connector 12 charges the battery box, while the liquid cooling plate 13 cools the bottom of the battery box. When thermal runaway occurs inside the battery, the robotic arm uses a battery retrieval rack to retrieve the thermally runaway battery box. The battery retrieval rack presses down on the pressure block 605 on the lifting plate 604, and the pressure block 605 causes the lifting plate 604 and the guide column 602 to move downward. Simultaneously, the elastic spring 603 is compressed, so that the height of the limiting block 606 is lower than that of the support plate 5. The battery retrieval rack pushes the battery box that has caused thermal runaway into the thermal runaway treatment chamber 3. The battery box that has caused thermal runaway contacts the guide wheel 9 on the support plate 5 and slides into the outside of the treatment sand box 7 at the rear of the thermal runaway treatment chamber 3. The staff moves the treatment sand box 7 to the position of the charging rack body 1, and then treats the battery box inside the treatment sand box 7 to prevent the battery box that has caused thermal runaway from affecting the other battery boxes.

[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.
