Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present utility model and its application or use. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

As used here, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0032] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present utility model. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the description. In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0033] As Figures 1 to 4 shown, applying the technical solution of this embodiment, the abnormal battery handling device of the battery swapping station includes: a placement rack 10, a water tank 20, and a bracket 30. The placement rack 10 has a normal battery placement position. The water tank 20 is arranged below the normal battery placement position, and the water tank 20 has an opening facing upward. An abnormal battery placement position is provided on the bracket 30, and the bracket 30 is detachably connected to the placement rack 10 to have a connection position and a separation position. Wherein, when the bracket 30 is in the connection position, the bracket 30 is connected to the placement rack 10, and the bracket 30 is located between the normal battery placement position and the opening. When the bracket 30 is in the separation position, the bracket 30 is located inside the water tank 20. In this way, when the bracket 30 is in the connection position, the abnormal battery 50 with thermal runaway in the battery swapping station can be placed on the abnormal battery placement position of the bracket 30, so that the abnormal battery 50 can be located between the normal battery placement position and the opening of the water tank 20, reducing the interference of the abnormal battery 50 on the normal batteries in case of fire and reducing the maintenance cost of the normal batteries. Moreover, when the bracket 30 is in the connection position, placing the abnormal battery 50 on the abnormal battery placement position of the bracket 30 enables the abnormal battery 50 to be observed. When the abnormal battery 50 with thermal runaway self-repairs, it can be taken away by the staff or put back on the placement rack 10, avoiding directly pushing the abnormal battery 50 with thermal runaway into the water tank 20 as in the related art and reducing the maintenance cost of the abnormal battery 50. Further, when the abnormal battery 50 with thermal runaway catches fire, the bracket 30 can be timely switched from the connection position to the separation position, so that the bracket 30 can drive the abnormal battery 50 into the water tank 20 for fire extinguishing operation, reducing the impact of the battery fire on other normal batteries. Therefore, the technical solution of this application effectively solves the problem in the related art of directly pushing the battery with thermal runaway or on fire into the water tank 20, which increases the maintenance cost of the batteries in the battery swapping station.

[0034] It should be noted that the battery will emit a thermal runaway signal before catching fire. The battery that emits the thermal runaway signal or the battery that catches fire is the abnormal battery 50. The battery that does not emit the thermal runaway signal is the normal battery.

[0035] As Figures 1 to 5 shown, a first lapping portion is provided on the placement rack 10, and a second lapping portion is provided on the bracket 30. The second lapping portion is lapped on the first lapping portion so that the bracket 30 is connected to the placement rack 10. The second lapping portion is misaligned with the first lapping portion so that the bracket 30 can be separated from the placement rack 10. The structures of the first lapping portion and the second lapping portion are simple and convenient for processing. Moreover, when the first lapping portion and the second lapping portion are misaligned, the bracket 30 can be separated from the placement rack 10, reducing the moving distance of the bracket 30 relative to the placement rack 10. Compared with taking the entire bracket 30 out of the placement rack 10 and then putting it into the water tank 20, the setting of this embodiment simplifies the moving path of the bracket 30, improves the efficiency of switching the bracket 30 from the connected position to the separated position, enables the abnormal battery 50 to be put into the water tank 20 more quickly after catching fire, and further reduces the influence of the abnormal battery 50 on the normal battery after catching fire.

[0036] In other embodiments, an avoidance portion is provided on the placement rack 10, and a third lapping portion is provided on the bracket 30. The third lapping portion is lapped on the placement rack 10 so that the bracket 30 is connected to the placement rack 10. The third lapping portion corresponds to the avoidance portion so that the bracket 30 can be separated from the placement rack 10. In this way, when the abnormal battery 50 catches fire, the bracket 30 can be moved so that the third lapping portion on the bracket 30 corresponds to the avoidance portion of the placement rack 10, enabling the bracket 30 to be separated from the placement rack 10 and putting the burning abnormal battery 50 into the water tank 20. Compared with taking the entire bracket 30 out of the placement rack 10 and then putting it into the water tank 20, the moving path of the bracket 30 is simplified, the efficiency of switching the bracket 30 from the connected position to the separated position is improved, the abnormal battery 50 can be put into the water tank 20 more quickly after catching fire, and the influence of the abnormal battery 50 on the normal battery after catching fire is further reduced.

[0037] As Figures 1 to 5As shown, when the first lapping part is provided on the placing rack 10 and the second lapping part is provided on the bracket 30, the first lapping part is the bump 11 and the second lapping part is the lapping block 37. The structures of the bump 11 and the lapping block 37 are simple and convenient for processing. A positioning structure is provided between the bump 11 and the lapping block 37. The setting of the positioning structure makes the lapping of the bump 11 and the lapping block 37 more reliable, so that the bracket 30 can be more stably and reliably held at the connection position without external force. The positioning structure includes a positioning protrusion 371 and a positioning groove 111 that is in positioning cooperation with the positioning protrusion 371. The positioning protrusion 371 is provided on the lapping block 37, and the positioning groove 111 is provided on the bump 11. The structures of the positioning protrusion 371 and the positioning groove 111 are simple and convenient for processing, and the positioning cooperation is reliable.

[0038] In other embodiments, the positioning groove 111 is provided on the lapping block 37, and the positioning protrusion 371 is provided on the bump 11.

[0039] As Figures 1 to 5 shown, the bump 11 and the lapping block 37 are polymer material blocks. The polymer material blocks have good anti-slip performance, so that the bracket 30 can be more stably and reliably held at the connection position without external force. In this embodiment, the bump 11 and the lapping block 37 are polyurethane material blocks.

[0040] In other embodiments, either the bump 11 or the lapping block 37 is a polymer material block.

[0041] As Figures 1 to 6 shown, the bracket 30 includes a frame 31 extending in the horizontal direction, a plurality of vertical rods 32 connected below the frame 31, and a plurality of support rods 33 connected to the plurality of vertical rods 32 at an angle. The vertical rods 32 extend in the vertical direction, the plurality of support rods 33 correspond to the plurality of vertical rods 32 one by one, and the second lapping part is provided on the frame 31. The structure of the bracket 30 is simple and compact, and convenient for processing. The frame 31, the vertical rods 32 and the support rods 33 can enclose an abnormal battery placement position for accommodating the abnormal battery 50, so as to facilitate the connection between the abnormal battery 50 and the bracket 30. The abnormal battery 50 is placed on the support rods 33, and the upper surfaces of the plurality of support rods 33 support the abnormal battery 50.

[0042] As Figures 1 to 6 shown, the frame 31 includes two cross bars 311 and a connecting rod 312 connected between the two cross bars 311. The structure of the frame 31 is simple and convenient for processing. When the first lapping part is provided on the placing rack 10 and the second lapping part is provided on the bracket 30, the second lapping part is provided on the lower surface of the end of the cross bar 311, so as to facilitate the lapping cooperation between the second lapping part and the first lapping part, that is, the lapping cooperation between the lapping block 37 and the bump 11, and also facilitate the installation of the second lapping part on the frame 31.

[0043] As Figures 1 to 6As shown, the bracket 30 further includes a connecting rod 34 connected between two vertical rods 32 and a reinforcing rod 35 connected between the connecting rod 34 and the supporting rod 33, so that the structure of the bracket 30 is more reliable and can withstand greater forces, facilitating the bracket 30 to more reliably hold the abnormal battery 50. The bracket 30 further includes a reinforcing rib 36 connected between the supporting rod 33 and the vertical rod 32, so that the structure of the bracket 30 is more reliable, improving the structural strength of the bracket 30, facilitating the bracket 30 to more reliably hold the abnormal battery 50.

[0044] In other embodiments, the bracket 30 further includes a connecting rod 34 connected between two vertical rods 32 and a reinforcing rod 35 connected between the connecting rod 34 and the supporting rod 33. Alternatively, the bracket 30 further includes a reinforcing rib 36 connected between the supporting rod 33 and the vertical rod 32.

[0045] As Figures 1 to 4 shown, the abnormal battery processing device of the battery swapping station further includes moving rollers 21 arranged below the water tank 20. The arrangement of the moving rollers 21 facilitates the movement of the water tank 20, facilitating the staff to take out the water tank 20 from below the placement rack 10, so as to facilitate the replacement of the liquid in the water tank 20. In this embodiment, the water tank 20 is made by welding stainless steel plates. The depth of the liquid in the water tank 20 needs to satisfy that after the abnormal battery 50 is placed in the water tank 20, the surface of the liquid is 100 mm higher than the upper surface of the abnormal battery 50.

[0046] As Figures 1 to 4 shown, the abnormal battery processing device of the battery swapping station further includes a smoke sensor and a controller. The smoke sensor is arranged on the placement rack 10, the smoke sensor is connected to the controller, and the controller is connected to the control of the palletizer 40 of the battery swapping station. In this way, when the smoke generated by the abnormal battery 50 on the bracket 30 connected to the placement rack 10 reaches the set value, the smoke sensor arranged on the placement rack 10 can sense that the abnormal battery 50 is on fire, so that the controller can control the palletizer 40 to drive the bracket 30 to move to the separation position, so that the abnormal battery 50 generating smoke can be placed into the water tank 20. The arrangement of the smoke sensor can perform a secondary confirmation on the abnormal battery 50 with thermal runaway, avoiding the problem of increasing the battery maintenance cost by putting all the abnormal batteries 50 into the water tank 20.

[0047] In other embodiments, the smoke sensor is arranged on the bracket 30.

[0048] This application also provides a battery swapping station, as Figures 1 to 3As shown in the figure, the battery swapping station includes a palletizer 40 and an abnormal battery handling device cooperating with the palletizer 40, and the abnormal battery handling device is the abnormal battery handling device of the above-mentioned battery swapping station. Since the abnormal battery handling device of the above-mentioned battery swapping station can solve the problem in the related art that a thermally out-of-control or on-fire battery is directly pushed into the water tank 20, which increases the maintenance cost of the batteries in the battery swapping station, the battery swapping station with this abnormal battery handling device can solve the same technical problem.

[0049] In this embodiment, when the abnormal battery 50 is placed on the bracket 30, there is an insertion gap between the lower surface of the frame 31 of the bracket 30 and the upper surface of the abnormal battery 50. The fork of the palletizer 40 is inserted into the insertion gap to lift the bracket 30 and the abnormal battery 50 simultaneously for easy movement.

[0050] The inventor found that in the related art, a power mechanism is used to push the battery to fall from the placement rack 10. The power mechanism in the related art includes guiding components or auxiliary moving components such as slide rails and sliders, and its structure is complex and the transmission is unreliable. When the placement position of the battery deviates from the center, the pushing of the power mechanism on the battery is prone to jamming, and the battery cannot be pushed into the water tank 20, resulting in a high failure rate. Moreover, setting an additional power mechanism increases the cost.

[0051] Therefore, in this embodiment, the palletizer 40 of the battery swapping station is used in cooperation with the abnormal battery handling device. The palletizer 40 is used to move normal batteries, and the palletizer 40 can also be used to switch the bracket 30 between the connection position and the separation position, reducing the setting of additional power mechanisms, lowering the cost, and the movement of the palletizer 40 is reliable. Moreover, by driving the bracket 30 with the palletizer 40 to move the abnormal battery 50, the requirement for the placement position of the abnormal battery is reduced, and the situation of jamming when the abnormal battery 50 moves is reduced.

[0052] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0053] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is inverted, a device described as "above" or "over" other devices or structures will then be positioned "below" or "under" the other devices or structures. Thus, the exemplary term "above" can include both the orientations of "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the corresponding interpretations of the spatial relative descriptions used herein will be made accordingly.

[0054] In addition, it should be noted that the use of terms such as "first", "second" etc. to define components is only for the convenience of differentiating the corresponding components. Without further statement, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of the present utility model.

[0055] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
