[0046] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0047] The following detailed description of the fire-fighting device for the battery swapping station and the overall structure, working principle, and technical effects of the battery swapping station provided by this utility model, through embodiments and in conjunction with the accompanying drawings, is a practical example.

[0048] A battery swapping station is an energy station that provides rapid battery swapping for electric vehicles (or other vehicles equipped with rechargeable batteries).

[0049] Power batteries (such as lithium batteries) can suffer damage to some extent due to various factors during frequent charging and discharging in daily use. For example, prolonged high-current charging and discharging can gradually change the structure of the electrode materials inside the battery, leading to a decline in battery performance. Poor heat dissipation during use can also accelerate battery aging and damage due to excessively high temperatures. If a lithium battery is damaged and continues to be charged, it is highly likely to trigger a series of serious problems. Therefore, battery swapping stations need to be equipped with appropriate fire-fighting devices.

[0050] Currently, fire-fighting equipment includes methods such as water flooding of batteries, aerosol fire suppression, and safety carpet fire suppression. However, because the batteries are inside the battery swapping station, fire suppression is difficult; or when the fire is large, it is difficult to completely extinguish.

[0051] To ensure the safety of the battery swapping station as a whole and its surrounding environment, this utility model provides a battery swapping station fire protection device and a battery swapping station to improve the above-mentioned problems.

[0052] Please see Figure 1 This embodiment provides a battery swapping station fire protection device and a battery swapping station equipped with the battery swapping station fire protection device. The battery swapping station fire protection device is used for battery fire protection work in the battery swapping station. When the battery pack 300 is detected to be in an abnormal state, it can promptly transfer the abnormal battery pack 300 to the outside of the battery swapping station, thereby facilitating the timely elimination of the abnormal state of the battery pack 300, such as replacement or extinguishing the fire.

[0053] This embodiment provides a battery swapping station fire-fighting device, including a fixing mechanism 100, a battery pack moving and lifting mechanism 200, and a driving component 400. The fixing mechanism 100 includes a first fixing component 110 and a second fixing component 120. The battery pack moving and lifting mechanism 200 is movably mounted on the fixing mechanism 100 and includes a moving component 210 and a lifting component 220 mounted on the moving component 210. The lifting component 220 is used to load the battery pack 300. The driving component 400 drives the battery pack moving and lifting mechanism 200 to move from the first fixing component 110 to the second fixing component 120 or back from the second fixing component 120 to the first fixing component 110.

[0054] like Figures 1 to 4 As shown, in this embodiment, the first fixing component 110 and the second fixing component 120 are arranged at intervals, and a partition protection structure 500 is provided between the first fixing component 110 and the second fixing component 120.

[0055] Specifically, the first fixing component 110 and the second fixing component 120 can be set on the inside and outside of the battery swapping station, respectively, wherein the partition protection structure 500 is a liftable roller shutter structure.

[0056] When the battery pack 300 is in a normal state, it is located at the first fixed component 110, i.e., inside the battery swapping station. When the battery pack 300 is in an abnormal state, the battery pack moving and lifting mechanism 200 moves from the first fixed component 110 to the second fixed component 120 through the driving component 400 (at this time, the partition protection structure 500 automatically rises), i.e., moves the battery pack 300 from the inside of the battery swapping station to the outside of the battery swapping station.

[0057] It is understood that, in other embodiments, the second fixing component 120 may also be located in other locations, such as in specific fire protection or isolation structures inside or outside the battery swapping station.

[0058] In addition, in this embodiment, the fixing mechanism 100 also includes a protective cover 140, which is semi-open and fixed on the second base plate 121, and is used to accommodate the abnormal battery pack 300.

[0059] The semi-open setting of the protective cover 140 means that, under normal circumstances, the protective cover 140 is a three-dimensional box-shaped structure composed of multiple partitions. In particular, the partitions are not provided on the side near the first fixing component 110, so that the battery pack moving lifting mechanism 200 can move the battery pack 300 into the box-shaped structure.

[0060] Specifically, when the battery pack 300 is in normal condition, the battery pack 300 is supported by the first fixing component 110;

[0061] When the battery pack 300 is in an abnormal state, the battery pack lifting mechanism 200 lifts the battery pack 300 and moves it to the second fixing component 120, and then lowers the battery pack 300 to the second fixing component.

[0062] In this embodiment, the first fixing component 110 includes a first base plate 111 and a first track 112 and a plurality of first support seats 113 respectively disposed on the first base plate 111; the second fixing component 120 includes a second base plate 121 and a second track 122 and a plurality of second support seats 123 respectively disposed on the second base plate 121.

[0063] Specifically, the first track 112 and the second track 122 are both used to support the movable component 210 and enable the movable component 210 to be movably mounted on the first track 112 and the second track 122.

[0064] The first support 113 and the second support 123 mentioned above are both used to support the battery pack 300. In this embodiment, there can be two first support 113 and two support 123, which are symmetrically arranged on the first base plate 111 and the second base plate 121 respectively, so as to stably fix the battery pack 300.

[0065] In addition, a fixing seat 130 is provided on the first base plate 111 or the second base plate 121, and the fixing seat 130 is used to install the driving component 400.

[0066] In this embodiment, one end of the driving member 400 is fixedly connected to the fixed base 130, and the other end is connected to the battery pack moving lifting mechanism 200 to drive the battery pack moving lifting mechanism 200 to slide on the first track 112 and the second track 122.

[0067] In this embodiment, the driving component 400 can be a cylinder.

[0068] Specifically, the cylinder body is fixedly mounted on the aforementioned fixed base 130, and the piston rod of the cylinder is connected to the battery pack moving lifting mechanism 200 to drive the movement of the battery pack moving lifting mechanism 200.

[0069] It is understood that in other embodiments, the drive element 400 may also be other telescopic structures, such as an electrically driven telescopic rod.

[0070] Please see Figure 2 and Figure 4 The battery pack moving lifting mechanism 200 includes a moving component 210 and a lifting component 220 disposed on the moving component 210; wherein, the lifting component 220 is used to load the battery pack 300, and the moving component 210 is used to drive the lifting component 220 and the battery pack 300 to move under the action of the driving component 400.

[0071] In this embodiment, the moving component 210 includes a walking base plate 211 and a plurality of wheels 212 disposed on the walking base plate 211; the plurality of wheels 212 are respectively connected to the corresponding first track 112 or second track 122.

[0072] It should be noted that the width of the wheel 212 should be greater than the gap between the first track 112 and the second track 122, so as to prevent the wheel 212 from getting stuck in the gap. In addition, the number of wheels 212 can be adapted to the actual working needs, and usually there are 4, which are respectively set at the four corners of the lower end face of the walking base plate 211.

[0073] In this embodiment, the lifting assembly 220 includes a support plate 221, multiple lifting components 222, and multiple guide components 223. The support plate 221 is fixed to the aforementioned walking base plate 211 by the multiple lifting components 222, and the support plate 221 is used to place and fix the battery pack 300.

[0074] Specifically, the lifting component 222 can be a lifting cylinder, with its cylinder body fixed on the traveling base plate 211 and the piston connected to the support plate 221.

[0075] Under normal conditions, the battery pack 300 is supported by the first support base 113 (i.e., at the first fixing component 110). When an abnormal state is detected in the battery pack 300, the lifting device 222 lifts upward, so that the support plate 221 contacts the battery pack 300 until the battery pack 300 disengages from the first support base 113. Then, under the action of the driving device 400, it moves to the second fixing component 120, and finally lowers the battery pack 300 until it contacts the second support base 123.

[0076] In this embodiment, the guide member 223 is used to provide limiting guidance to the support plate 221; specifically, the guide member 223 can be a linear bearing, and the support plate 221 is provided with a corresponding guide rod structure. The guide rod is connected to the linear bearing to realize the positioning guidance of the support plate 221 in the height direction.

[0077] It is understandable that the number of guide members 223 and guide rods can be adaptively selected according to actual needs. In this embodiment, the number of guide members 223 and guide rods is 4, which are respectively set at the four corners of the lower end face of the support plate 221.

[0078] In this embodiment, the battery pack 300 is connected to the fixing mechanism 100 or the lifting assembly 220 via a battery pack support base 310. The battery pack support base 310 includes a support base plate 311 for supporting the battery pack 300.

[0079] In this embodiment, positioning pins are provided on the first support base 113, the second support base 123, and the support plate 221, and corresponding pin holes are provided on the lower end face of the support base plate 311 so that the battery pack support base 310 can be accurately placed on the first support base 113, the second support base 123, or the support plate 221.

[0080] Please see Figure 5In this embodiment, in order to isolate the abnormal battery pack 300, the battery pack support 310 further includes a protective cover 312 disposed on one side of the support base plate 311. When the battery pack moving lifting mechanism 200 moves to the second fixing component 120, the protective cover 140 and the protective cover 312 form a sealed structure covering the battery pack 300. This sealed structure can isolate the abnormal battery pack 300 on the one hand, and on the other hand, when the abnormal battery pack 300 is in a fire state, the sealed space can play a certain role in controlling the fire.

[0081] It should be noted that in other embodiments, the protective cover 140 can also be other fire protection or isolation structures. It is understood that it can also be installed inside the battery swapping station to complete the isolation and fire protection work of the abnormal battery pack 300.

[0082] It is understood that, in order to isolate and fire the abnormal battery pack 300, this embodiment also includes multiple other sensors, such as smoke sensors and temperature sensors. These sensors should be electrically connected to the battery pack moving and lifting mechanism 200 and the drive unit 400, respectively. In order to identify the working status of the battery pack 300, this embodiment also includes at least one control structure, such as a programmable logic controller.

[0083] The aforementioned sensors and control structures can be conventional technologies, and will not be described in detail here.

[0084] The specific working process of the fire-fighting device for a battery swapping station provided in this embodiment is as follows:

[0085] When the battery pack 300 is in normal condition, the battery pack 300 is located at the first fixing component 110 and fixed to the first support base 113 by the battery pack support base 310.

[0086] When an abnormal state is detected in the battery pack 300, the isolation protection structure 500 opens, and the lifting assembly 220 lifts the battery pack support 310 until it detaches from the first support 113. Then, the drive component 400 drives the moving assembly 210 to move the battery pack support 310 to the second fixing assembly 120. At this time, the protective cover 140 and the protective cover plate 312 form a sealed structure covering the battery pack 300. After reaching the position, the lifting assembly 220 lowers the battery pack support 310 until it contacts the second support 123. Finally, the drive component 400 drives the battery pack moving lifting mechanism 200 back to the first fixing assembly 110.

[0087] This embodiment can achieve at least the following technical effects:

[0088] When the battery pack 300 malfunctions, the lifting assembly 220 lifts the battery pack 300 to detach it from the fixing mechanism 100. At this time, the moving assembly 210, in conjunction with the driving component 400, pushes the battery pack 300 from its original position to another position, thereby preventing the fire caused by the battery pack 300 malfunctioning and catching fire from spreading.

[0089] By using the protective cover 140 installed on the second base plate 121, the battery pack 300 that is in an abnormal state or on fire can be moved into the protective cover 140 under the action of the drive unit 400, thereby isolating the abnormal battery pack 300 and reducing potential hazards.

[0090] The battery pack 300 is fixed to the lifting assembly 220 by the battery pack support 310. On the one hand, this isolates the battery pack 300 from the lifting assembly 220 and improves the positioning and fixing performance of the battery pack 300. On the other hand, when the battery pack 300 is pushed out of the battery swapping station by the drive unit 400, the protective cover 312 and the protective cover 140 on one side of the battery pack 300 fixing base 130 together form a sealed structure to cover the battery pack 300, thereby isolating the abnormal battery pack 300 and preventing the spread of fire caused by its ignition. At the same time, the sealed structure can also play a certain role in controlling the fire.

[0091] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
