Description

Technical Field

[0001] The present invention relates to the field of battery replacement, and in particular to an emergency processing device and a battery replacement station or an energy storage station. Background Art

[0002] Electric vehicles have the advantages of zero emissions, low noise, and economical operation and maintenance, and are becoming more and more popular among users. The energy used by electric vehicles is the electricity provided by the power battery pack on board. Electric vehicles need to be charged after the electricity is used up. Due to the limitations of existing battery technology and charging technology, it takes a long time to fully charge an electric vehicle, which is not as simple and fast as refueling a fuel vehicle directly. Therefore, in order to reduce the waiting time of users, replacing the battery when the electric vehicle is running out of power is an effective means. In order to facilitate the replacement of batteries for electric vehicles and meet the battery replacement needs of electric vehicles, it is necessary to build battery replacement stations. With the rapid popularization of electric vehicles, more battery replacement stations need to be built to meet the demand.

[0003] On the one hand, the battery swap station is used to store a number of batteries to meet the needs of electric vehicles for rapid battery swapping, and on the other hand, it is also used to maintain and charge the replaced batteries. However, when storing or charging, very individual batteries may have problems and generate high temperatures, release toxic gases, and even cause fires or explosions. For this type of thermal runaway battery, emergency treatment is required. The usual practice is to remove the thermal runaway battery from the charging rack by a palletizer and transfer it to a battery swap cart, and then use the battery swap cart to quickly transport it from the entrance door of the battery swap station to the outside of the battery swap station for safe treatment, or transfer the thermal runaway battery to an explosion-proof fire extinguishing device. For example, in patent publication number CN111921134A, an explosion-proof fire extinguishing device and an explosion-proof treatment method are disclosed. The explosion-proof fire extinguishing device is used to carry and store power batteries. When the power battery is in an abnormal state, the support bracket can be driven to move to an explosion-proof position by an actuator. However, this explosion-proof fire-extinguishing device cannot automatically and quickly transfer the thermal runaway battery to an explosion-proof position when a thermal runaway battery on a battery rack or in a battery swap station is transferred thereto. The thermal runaway battery must first be placed on the explosion-proof fire-extinguishing device, and then manual operation is required to use the actuator to drive the support bracket to move to the explosion-proof position. This firstly increases the number of operating steps, prolongs the time for emergency response, and increases the safety risk of the battery swap station. Secondly, manual operation is required, which increases the safety risk of the operator if the battery condition further deteriorates during the process of handling the thermal runaway battery. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defect that the explosion-proof fire extinguishing device in the prior art cannot automatically and quickly handle the thermal runaway battery, and to provide an emergency handling device and a battery swap station or energy storage station.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] An emergency handling device, used in a battery swap station or an energy storage station, the emergency handling device comprises a box, a guide slide assembly and a trigger assembly, the box has a receiving cavity with an upper opening, the guide slide assembly is located above the receiving cavity, the trigger assembly is located below the guide slide assembly and abuts against the guide slide assembly, and the guide slide assembly and the trigger assembly are respectively arranged to be movably connected to the box; the upper surface of the guide slide assembly is provided with a guide slide surface, and the guide slide surface is extended from a first side of the box toward the direction of the trigger assembly;

[0007] When the heavy object slides onto the trigger assembly along the guide sliding surface, the trigger assembly is displaced so that the guide sliding assembly is separated from the abutment of the trigger assembly, so that the heavy object falls into the accommodating cavity.

[0008] In this solution, when a heavy object is placed on the emergency handling device, it will automatically slide along the guide surface to the trigger assembly. The trigger assembly is displaced under load, so that the guide surface and the trigger assembly are separated, and the heavy object automatically slides from the trigger assembly to the accommodating chamber of the emergency handling device; and because the guide surface is set, the heavy object can slide a certain distance along the setting direction of the guide surface before falling into the accommodating chamber, which is convenient for dropping a heavy object at the near end to the far end through the guide surface, and the operation is convenient, and no manual intervention is required, which greatly improves safety. At the same time, the guide surface on the guide assembly also allows the heavy object to slide along the setting direction of the guide surface, which is convenient for accurately triggering the trigger assembly and accurately falling into the box, thereby improving the reliability of the device.

[0009] Preferably, the movable connection is a hinge.

[0010] In this solution, the above structure is adopted to limit the movement of the guide assembly and the trigger assembly within a certain range, and also facilitate the subsequent reset. When the guide assembly and the trigger assembly are out of contact, they can rotate around their own hinge points respectively, and the movement is stable and reliable.

[0011] Preferably, the guide slide assembly includes a first hinged end and a contact end, the first hinged end is located on a first side of the box body and hinged to an upper end of the box body, and the contact end is located on the other side opposite to the first hinged end and abuts against the trigger assembly.

[0012] In this solution, the above-mentioned structural form is adopted. When the contact end is separated from the trigger assembly, the guide slide assembly can be turned downward by gravity without external force driving.

[0013] Preferably, the guide sliding surface is arranged between the first hinge end and the contact end, and is arranged to extend obliquely downward in a direction from the first hinge end toward the contact end.

[0014] In the present solution, the above-mentioned structural form is adopted. When a heavy object is placed on the guide slide, due to the inclined guide slide, the heavy object can slide toward the trigger assembly by gravity without external force.

[0015] Preferably, the guide sliding assembly includes a bracket, the two ends of the bracket located at the first hinged end are respectively hinged to the upper ends of the opposite side walls of the box body, at least one end of the bracket located at the contact end is abutted against the trigger assembly, and the guide sliding surface is arranged on the upper surface of the bracket.

[0016] In this solution, the bracket has a simple structure, is easy to support and rotates smoothly, thereby improving the stability and reliability of the device.

[0017] Preferably, the guide slide assembly includes a bracket and a guide rail, the two ends of the bracket located at the first hinged end are respectively hinged to the upper ends of the opposite side walls of the box body, at least one end of the bracket located at the contact end abuts against the trigger assembly, the number of the guide rails is two, the two guide rails are arranged in parallel and installed on the bracket, the guide rails are arranged to extend downwardly in an inclined manner from the first hinged end toward the contact end, and the guide slide surface is arranged on the upper surface of the guide rail.

[0018] In this solution, the bracket has a simple structure, is easy to support and rotates smoothly, thereby improving the stability and reliability of the device. In addition, the sliding speed of the heavy object can be adjusted by setting different inclination angles of the guide rail.

[0019] Preferably, a plurality of rollers arranged side by side are mounted on the guide surface of each guide rail.

[0020] In this solution, the above-mentioned structural form is adopted to reduce the friction between the heavy object and the guide rail, making it easier for the heavy object to slide smoothly into the box.

[0021] Preferably, the trigger assembly includes a second hinged end, a supporting end and a trigger end, the trigger end is located on the second side of the box body opposite to the first side of the box body, and the trigger end is located at the lower end of the box body and has a first preset distance from the bottom surface of the box body, the supporting end is arranged below the contact end to support the contact end, and the second hinged end is located below the supporting end and is hinged to the lower end of the box body.

[0022] In the present solution, since the trigger end is arranged on the second side of the box body, and the second hinge end is arranged between the first side of the box body and the second side of the box body, when the heavy object slides onto the trigger end, the trigger assembly loses balance and flips outward around its own hinge point, and the supporting end is separated from the contact end, causing the guide sliding assembly to lose balance and flip downward around its own hinge point under the action of gravity, thereby causing the heavy object to fall into the box body.

[0023] Preferably, the value of the first preset distance is between 1 / 10 and 1 / 5 of the length from the second hinge end to the trigger end.

[0024] In this solution, the above structure is adopted to control the flipping angle of the trigger assembly to a preset angle value, and this preset angle value only needs to satisfy the separation of the support end and the contact end. When the trigger end moves downward by the first preset spacing value, it will be blocked by the bottom surface of the box and stop flipping outwards. At this time, the support end and the contact end have been separated, so that the heavy object flips toward the middle of the box and finally falls into the middle of the box.

[0025] Preferably, the trigger assembly comprises a rotating shaft, a support member and a trigger member, the rotating shaft is located at the second hinged end and extends along the width direction of the box body, both ends of the rotating shaft are hinged to the inner wall of the box body, the lower end of the support member is connected to the rotating shaft, and the upper end of the support member forms the supporting end and supports the contact end from below, one end of the trigger member is connected to the rotating shaft, the other end of the trigger member extends toward the second side of the box body and gradually increases the distance from the bottom surface of the box body, and the other end of the trigger member forms the trigger end;

[0026] When the heavy object slides onto the trigger member, the support member flips around the rotation axis toward the second side of the box body, and the support member is separated from the contact end.

[0027] In this solution, the above-mentioned structural form is adopted so that the support member can rotate smoothly with the rotating shaft. Since the trigger end of the trigger member is arranged on the second side of the box body, and the rotating shaft is arranged between the first side of the box body and the second side of the box body, when the heavy object slides onto the trigger end, the trigger member loses balance, driving the rotating shaft to rotate outward, and at the same time, the support member rotates synchronously with the rotating shaft because it is connected to the rotating shaft, so that the support end is separated from the contact end, causing the guide slide assembly to lose balance and flip downward around its own hinge point under the action of gravity, thereby causing the heavy object to fall into the box body.

[0028] Preferably, an upper end of a side wall of the support member facing the first side of the box body is provided with an abutment portion extending toward the first side of the box body, and the abutment portion and the side wall of the support member form a limiting step to support the contact end.

[0029] In this solution, the above-mentioned structural form is adopted. When the contact end of the guide slide assembly abuts against the limiting step, the limiting step supports and limits the contact end of the guide slide assembly to prevent the guide slide assembly from flipping downward. When the heavy object slides from the guide slide surface to the trigger end of the trigger member, causing the support member to flip, the contact end of the guide slide assembly slides off the support member and flips around its own hinge point, and the heavy object falls into the box.

[0030] Preferably, the trigger assembly also includes a limiting portion, which is arranged at the upper end of the support member and extends toward the outside of the box body along the width direction of the box body, and the limiting portion is located above the upper frame of the box body and is separated from the upper frame of the box body by a second preset distance; the upper frame of the box body is provided with a limiting member, and the limiting member is located at a position where an extension line of the contact end along the width direction of the box body intersects with the upper frame of the box body when the contact end is supported by the support member, and the limiting member cooperates with the limiting portion so that the trigger assembly is limited when it is flipped toward the first side of the box body.

[0031] In this solution, the above-mentioned structural form is adopted, and the limiting member cooperates with the limiting portion so that the trigger assembly is limited when it flips toward the first side of the box body, so that the trigger assembly remains in a state of supporting the guide slide assembly when not triggered by a heavy object, thereby improving the stability of the device.

[0032] Preferably, the value of the second preset distance is not less than 10 mm.

[0033] In this solution, the above-mentioned structural form is adopted to ensure that the support member has a sufficient flipping path so that the contact end of the guide slide assembly is completely separated from the support member after flipping, thereby realizing the downward flipping of the guide slide assembly.

[0034] Preferably, the trigger assembly further includes an elastic element, one end of which is connected to the support member, and the other end of which is connected to the box body, and the elastic element applies a force to prevent the trigger assembly from flipping toward the second side of the box body when the trigger assembly is not triggered.

[0035] In this solution, the elastic element applies a force to make the limit portion abut against the limit member, and the support member remains in a state of supporting the contact end of the guide slide assembly, so that the emergency handling device is in a state to be triggered. After the heavy object falls into the accommodating chamber, the elastic element provides a restoring force to restore the trigger assembly to its initial position.

[0036] Preferably, there are two supporting members, and the two supporting members are respectively disposed at two ends of the rotating shaft.

[0037] In this solution, the above-mentioned structural form is adopted to improve the stability and reliability of the emergency handling device in the two states of flipping and supporting.

[0038] Preferably, the distance between the two support members is not less than the outer diameter of the weight.

[0039] In this solution, the above-mentioned structural form is adopted to facilitate the heavy object to flip backward and fall into the middle part of the box body without being blocked by the support member.

[0040] Preferably, the number of the triggering members is one or more, and the triggering members are arranged at intervals along the axial direction of the rotating shaft, and connecting members are arranged between adjacent triggering members.

[0041] In this solution, the above-mentioned structural form is adopted to form a trigger frame with a wider area, so that heavy objects sliding down from the guide slide surface can slide onto the trigger frame and trigger the rotation axis to flip.

[0042] Preferably, the upper end of the box body has a blocking wall, the blocking wall is arranged on a second side of the box body opposite to the first side of the box body, and the height of the blocking wall is higher than the height of the guide slide assembly.

[0043] In this solution, the above-mentioned structural form is adopted, and the blocking wall is used to block the heavy object from falling into the box body and prevent the heavy object from sliding out of the box body.

[0044] Preferably, a drain valve is provided at the bottom of the box.

[0045] In this solution, the drain valve is used to drain the water in the box.

[0046] Preferably, the emergency handling device further comprises a plurality of legs, and the plurality of legs are spaced apart at the bottom of the box body so that there is a gap between the bottom surface of the box body and the bottom surface on which the box body is placed.

[0047] In this solution, the above-mentioned structural form is adopted, which, on the one hand, facilitates the arrangement of the drain valve at the bottom of the box body, and on the other hand, also protects the bottom of the box body and reduces corrosion.

[0048] A battery swap station or energy storage station, comprising the above-mentioned emergency processing device.

[0049] In this solution, the thermal runaway batteries in the battery swap station can be put into the emergency treatment device, and the water installed in the box can be used to cool them down and isolate them from the air to prevent the thermal runaway batteries from burning or exploding, thereby improving the safety of the battery swap station.

[0050] Preferably, the battery swap station also includes a battery swap station body, and the energy storage station also includes an energy storage station body. An emergency exit is provided on the side wall of the battery swap station body or the energy storage station body. The emergency handling device is provided outside the battery swap station body or the energy storage station body and is adjacent to the emergency exit, and is used to receive and dispose of batteries transferred from the emergency exit to the outside of the battery swap station body or the energy storage station body.

[0051] In this solution, the above-mentioned structural form is adopted to facilitate the transfer of the thermal runaway battery in the battery swap station body or the energy storage station body to the outside of the battery swap station body or the energy storage station body through the emergency exit, shortening the transportation path of the thermal runaway battery, reducing the transportation time, and improving the disposal efficiency of the thermal runaway battery.

[0052] On the basis of being in accordance with the common sense in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present invention.

[0053] The positive and progressive effects of the present invention are: when a heavy object is placed on the emergency handling device, it will automatically slide along the guide surface to the trigger assembly, and the trigger assembly will be displaced under load, so that the guide surface and the trigger assembly are separated, and the heavy object will automatically slide from the trigger assembly to the accommodating chamber of the emergency handling device; and because the set guide surface allows the heavy object to slide a certain distance along the setting direction of the guide surface before falling into the accommodating chamber, it is convenient to drop the heavy object at the near end to the far end through the guide surface, which is easy to operate and does not require manual intervention, greatly improving safety. At the same time, the guide surface on the guide assembly also allows the heavy object to slide along the setting direction of the guide surface, which is convenient for accurately triggering the trigger assembly and accurately falling into the box, improving the reliability of the device.

[0082] The present invention will be described more clearly and completely below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0083] like Figure 1-Figure 7 As shown, the present invention discloses an emergency handling device, which can be used in a battery swap station or an energy storage station to perform emergency treatment on thermal runaway batteries. The emergency handling device includes a housing 1, a guide slide assembly 2, and a trigger assembly 3. The housing 1 has a accommodating cavity with an upper opening, the guide slide assembly 2 is located above the accommodating cavity, the trigger assembly 3 is located below the guide slide assembly 2 and abuts against the guide slide assembly 2, and the guide slide assembly 2 and the trigger assembly 3 are respectively configured to be movably connected to the housing 1, so that when the trigger assembly 3 is displaced by a loaded weight, the guide slide assembly 2 is separated from the trigger assembly 3 to allow the weight to fall into the housing 1.

[0084] like Figure 1As shown, in order to enable the heavy object to accurately trigger the trigger assembly 3, a guide sliding surface 201 is provided on the upper surface of the guide sliding assembly 2, and the guide sliding surface 201 is extended from the first side 11 of the box body toward the trigger assembly 3, so that the heavy object can automatically slide along the setting direction of the guide sliding surface 201 after being placed on the emergency handling device, and can trigger the trigger assembly 3. The setting of the guide sliding surface 201 can also enable the heavy object to slide a certain distance along the setting direction of the guide sliding surface 201 before falling into the accommodating cavity, so that the heavy object can be dropped to the far end through the guide sliding surface 201 when dropped at the near end, and the operation is convenient.

[0085] When the heavy object slides along the guide surface 201 onto the trigger component 3, the trigger component 3 is displaced to allow the guide surface 2 to break away from the abutment of the trigger component 3, so that the heavy object automatically falls into the accommodating cavity, thereby improving the disposal efficiency of the thermal runaway battery and preventing the heavy object from falling directly from a height into the box body 1, reducing the impact force on the heavy object and improving safety.

[0086] For a battery swap station or energy storage station, the battery swap station also includes a battery swap station body, and the energy storage station also includes an energy storage station body. Batteries are stored in the battery swap station body or the energy storage station body. The battery may have problems during charging or storage, causing the temperature to rise and requiring emergency treatment. In this embodiment, the heavy object is a thermal runaway battery. In order to quickly transfer the thermal runaway battery from the battery swap station body or the energy storage station body to the outside, it is only necessary to transfer the thermal runaway battery to the guide surface 201 on the guide assembly 2, and the thermal runaway battery can slide along the guide surface 201 to the emergency treatment device provided outside the battery swap station or the energy storage station. When the thermal runaway battery slides onto the trigger component 3, the trigger component 3 is separated from the guide component 2, and the thermal runaway battery automatically falls into the box 1. The box 1 contains water or other fire extinguishing materials. Water and other fire extinguishing materials can cool the thermal runaway battery and isolate it from the air, thereby preventing the thermal runaway battery from burning or exploding, and improving the safety of the battery swap station or energy storage station. At the same time, due to the structural design of the emergency handling device, after the thermal runaway battery is transferred to the outside of the battery swap station or energy storage station and enters the emergency handling device, no human intervention is required, thereby avoiding personal accidents and greatly improving safety.

[0087] In this embodiment, the movable connection is a hinge to limit the movement of the guide assembly 2 and the trigger assembly 3 within a certain range, and also facilitate the subsequent reset. When the guide assembly 2 and the trigger assembly 3 are out of contact, they can rotate around their own hinge points respectively, and the movement is smooth and reliable. Of course, in other embodiments, the movable connection can also be a sliding connection.

[0088] like Figure 1 and Figure 4As shown, the guide assembly 2 includes a first hinge end 2a and a contact end 2b, wherein the first hinge end 2a is located at the first side 11 of the box body and is hinged to the upper end of the box body 1, and the contact end 2b is located at the other side opposite to the first hinge end 2a and abuts against the trigger assembly 3. When the contact end 2b is separated from the trigger assembly 3, the guide assembly 2 can be turned downward by gravity without external force.

[0089] like Figure 4 As shown, the guide sliding surface 201 is arranged between the first hinge end 2a and the contact end 2b, and is arranged to extend downwardly along the first hinge end 2a toward the contact end 2b. When a heavy object is placed on the guide sliding surface 201, due to the inclined guide sliding surface 201, the heavy object can slide toward the trigger assembly 3 by gravity without external force.

[0090] like Figure 5 As shown, in this embodiment, the guide assembly 2 includes a bracket 21 and a guide rail 22. The two ends of the bracket 21 located at the first hinge end 2a are respectively hinged to the upper ends of the opposite side walls of the box body 1, and at least one end of the bracket 21 located at the contact end 2b is abutted against the trigger assembly 3. The bracket 21 has a simple structure, is easy to support and rotates smoothly, and improves the stability and reliability of the device.

[0091] like Figure 4 and Figure 5 As shown, the guide rail 22 is arranged to extend downwardly from the first hinge end 2a toward the contact end 2b, and the guide sliding surface 201 is arranged on the upper surface of the guide rail 22, so that the heavy object can slide along the setting direction of the guide rail 22 by gravity without external force. There are two guide rails 22, which are arranged in parallel and installed on the bracket 21, which can effectively support the heavy object and reduce the contact area between the heavy object and the guide sliding surface 201, thereby reducing friction. At the same time, the sliding speed of the heavy object can be adjusted by setting different inclination angles of the guide rail 22.

[0092] In other embodiments, the guide sliding assembly includes a bracket, and the two ends of the bracket located at the first hinged end are respectively hinged to the upper ends of the opposite side walls of the box body, and at least one end of the bracket located at the contact end is abutted against the trigger assembly. The guide sliding surface is directly arranged on the upper surface of the bracket, and the structure is simple.

[0093] like Figure 5 As shown, in order to reduce the friction between the heavy object and the guide rail 22, a plurality of rollers 23 arranged side by side are installed on the guide surface of each guide rail 22.

[0094] like Figure 1 and Figure 4As shown, the trigger assembly 3 includes a second hinge end 3a, a support end 3b and a trigger end 3c, the trigger end 3c is located at the second side 12 of the box body opposite to the first side 11 of the box body, and the trigger end 3c is located at the lower end of the box body 1 and has a first preset distance from the bottom surface of the box body 1, the support end 3b is arranged below the contact end 2b to support the contact end 2b, and the second hinge end 3a is located below the support end 3b and is hinged to the lower end of the box body 1. Since the trigger end 3c is arranged at the second side 12 of the box body, and the second hinge end 3a is arranged between the first side 11 of the box body and the second side 12 of the box body, when the heavy object slides onto the trigger end 3c, the trigger assembly 3 loses balance and turns outward around its own hinge point, then the support end 3b is separated from the contact end 2b, causing the guide assembly 2 to lose balance and turn downward around its own hinge point under the action of gravity, thereby causing the heavy object to fall into the box body 1.

[0095] The value of the first preset spacing is between 1 / 10 and 1 / 5 of the length from the second hinge end 3a to the trigger end 3c, so that the flip angle of the trigger assembly 3 is controlled within the preset angle value, and this preset angle value only needs to satisfy the separation of the support end 3b from the contact end 2b. When the trigger end 3c moves downward by the first preset spacing value, it will be blocked by the bottom surface of the box body 1 and stop flipping outwards, and at this time, the support end 3b and the contact end 2b have been separated, so that the heavy object flips toward the middle of the box body 1 and finally falls into the middle of the box body 1.

[0096] like Figure 1 , Figure 4 and Figure 6 As shown, the trigger assembly 3 includes a rotating shaft 31, a support member 32 and a trigger member 33. The rotating shaft 31 is located at the second hinge end 3a and extends along the width direction 100 of the box body. Both ends of the rotating shaft 31 are hinged to the inner wall of the box body 1. The lower end of the support member 32 is connected to the rotating shaft 31, and the upper end of the support member 32 forms a support end 3b and supports the contact end 2b from below. One end of the trigger member 33 is connected to the rotating shaft 31, and the other end of the trigger member 33 extends toward the second side 12 of the box body and gradually increases the distance from the bottom surface of the box body. The other end of the trigger member 33 forms a trigger end 3c. Since the trigger end 3c of the trigger member 33 is arranged on the second side 12 of the box body, and the rotating shaft 31 is arranged between the first side 11 of the box body and the second side of the box body, when the heavy object is placed on the guide sliding assembly 2 from the first side of the box body and slides to the trigger end 3c through the guide sliding assembly 2, the trigger member 33 loses balance, driving the rotating shaft 31 to rotate outward, and at the same time, the support member 32 rotates synchronously with the rotating shaft 31 due to being connected to the rotating shaft 31, so that the support end 3b is disengaged from the contact end 2b, causing the guide sliding assembly 2 to lose balance and flip downward around its own hinge point under the action of gravity, thereby causing the heavy object to fall into the box body 1.

[0097] like Figure 2-Figure 4As shown, the upper end of the side wall of the support member 32 facing the first side 11 of the box body is provided with a supporting portion 321 extending toward the first side 11 of the box body, and the supporting portion 321 and the side wall of the support member 32 form a limiting step to support the contact end 2b. When the contact end 2b of the guide slide assembly 2 abuts against the limiting step, the limiting step supports and fixes the contact end 2b of the guide slide assembly 2 to prevent the guide slide assembly 2 from flipping downward. When a heavy object slides from the guide slide surface 201 to the trigger end 3c of the trigger member 33, causing the support member 32 to flip, the contact end 2b of the guide slide assembly 2 slides off the limiting step of the support member 32 and flips around its own hinge point, and the heavy object falls into the box body 1.

[0098] like Figure 2 and Figure 3 As shown, in order to control the angle of the trigger assembly 3 flipping toward the direction close to the first side wall at an appropriate position, the trigger assembly 3 also includes a limiter 322, which is arranged at the upper end of the support member 32 and extends toward the outside of the box body 1 along the width direction 100 of the box body, and the limiter 322 is located above the upper frame of the box body 1 and is separated from the upper frame of the box body 1 by a second preset spacing. The upper frame of the box body 1 is provided with a limiter 14, which is located at a position where the extension line of the contact end 2b along the width direction 100 of the box body intersects with the upper frame of the box body when the contact end 2b is supported by the support member 32, and the limiter 14 cooperates with the limiter 322 to limit the trigger assembly 3 when flipping toward the first side 11 of the box body, so that the trigger assembly 3 can remain in the state of supporting the guide slide assembly 2 when it is not triggered by a heavy object, thereby improving the stability of the device.

[0099] The value of the second preset spacing is not less than 10 mm, so as to ensure that the support member 32 has a sufficient flipping path, so that the contact end 2b of the guide slide assembly 2 is completely separated from the support member 32 after flipping, thereby realizing the downward flipping of the guide slide assembly 2. At the same time, when the support member 32 flips to the limit portion 322 against the side wall edge of the box body 1, the limit portion 322 prevents the support member 32 from further flipping, so as to control the flipping angle of the support member 32 within a suitable range. When a heavy object falls into the box body 1, it is convenient for the support member 32 to quickly reset under the action of external force.

[0100] like Figure 3 As shown, in order to keep the trigger assembly 3 in the state to be triggered, the trigger assembly 3 also includes an elastic element 34, one end of the elastic element 34 is connected to the support member 32, and the other end of the elastic element 34 is connected to the box 1. The elastic element 34 applies a force to make the limit portion 322 abut against the limit member 14, so as to prevent the trigger assembly 3 from turning toward the second side 12 of the box when the trigger assembly 3 is not triggered, and keep the support member 32 in the state of supporting the contact end 2b of the guide slide assembly 2, so that the emergency handling device is in the state to be triggered. After the heavy object falls into the accommodating chamber, the elastic element 34 also provides a restoring force to restore the trigger assembly 3 to its initial position.

[0101] like Figure 4 and Figure 6 As shown, in order to improve the stability of the support, there are two support members 32, which are respectively arranged at both ends of the rotating shaft 31, so as to improve the stability and reliability of the emergency handling device in the two states of flipping and supporting. In addition, the distance between the two support members 32 is not less than the outer diameter of the weight, so that the weight can flip backward and fall into the middle of the box body 1 without being blocked by the support members 32.

[0102] The number of the trigger members 33 is one or more, and each trigger member 33 is arranged at intervals along the axial direction of the rotating shaft 31. Connectors are provided between adjacent trigger members 33 to form a trigger frame with a wider area, so that heavy objects sliding down from the guide surface 201 can slide onto the trigger frame and trigger the rotating shaft 31 to flip.

[0103] like Figure 1 and Figure 2 As shown, in order to prevent heavy objects from sliding out of the box body 1, the upper end of the box body 1 has a blocking wall 13, which is arranged on the second side 12 of the box body opposite to the first side 11 of the box body, and the height of the blocking wall 13 is higher than the height of the sliding guide assembly 2.

[0104] like Figure 7 As shown, a drain valve 15 is provided at the bottom of the box body 1 for draining water in the box body 1 .

[0105] like Figure 1 , Figure 2 and Figure 7 As shown, the emergency treatment device further includes a plurality of legs 16, which are arranged at intervals at the bottom of the box body 1 so that there is a gap between the bottom surface of the box body 1 and the bottom surface on which the box body 1 is placed. The arrangement of the legs 16, on the one hand, facilitates the arrangement of the drain valve 15 at the bottom of the box body 1 so that the water in the box can be completely drained, and on the other hand, the bottom of the box body 1 is protected to reduce corrosion.

[0106] The present invention also discloses a battery swap station or energy storage station, which includes the above-mentioned emergency treatment device and a battery swap station body or energy storage station body. When a problem occurs in the battery in the battery swap station body or energy storage station body and leads to thermal runaway, the thermal runaway battery can be promptly put into the emergency treatment device and placed on the guide slide assembly 2. The thermal runaway battery slides on the guide slide assembly 2 toward the second side 12 of the box of the emergency treatment device until it touches the trigger end 3c of the trigger assembly 3. The trigger end 3c of the trigger assembly 3 is compressed, causing the trigger assembly 3 to rotate around its own hinge point, so that the guide slide assembly 2 switches from being supported by the trigger assembly 3 to the guide slide assembly 2 being separated from the abutment of the trigger assembly 3, so that the guide slide assembly 2 flips and cannot support the thermal runaway battery, and the thermal runaway battery falls into the box of the emergency treatment device. Water or other fire extinguishing substances can be pre-injected into the box of the emergency treatment device. The thermal runaway battery is cooled and isolated from the air by the fire extinguishing substances such as water set in the box 1, so as to prevent the thermal runaway battery from burning or exploding, thereby improving the safety of the battery swap station.

[0107] In order to facilitate the rapid transfer of thermal runaway batteries, an emergency exit is set on the side wall of the battery swap station body or the energy storage station body, and the emergency handling device is arranged outside the battery swap station body or the energy storage station body and adjacent to the emergency exit, so as to receive the batteries transferred from the emergency exit to the outside of the battery swap station body or the energy storage station body and dispose of them, thereby shortening the transportation path of the thermal runaway batteries, reducing the transportation time, and improving the disposal efficiency of the thermal runaway batteries.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
