Description

Technical Field

[0001] This invention relates to the field of power supply technology for electric vehicles, and in particular to an intelligent and safe battery swapping cabinet. Background Technology

[0002] A battery swapping cabinet is a device used to store and charge batteries. When using a battery swapping cabinet, the depleted battery is placed inside, and the fully charged battery is removed, which makes people's lives more convenient and improves their quality of life.

[0003] The battery swapping cabinet resembles a storage locker, containing different battery compartments, each holding one power battery. The cabinet door is controlled by a controller to open and close, allowing for battery retrieval and storage. Each battery compartment is connected to a charger, automatically charging the batteries within. Electric vehicles can use these cabinets for self-service battery swapping, eliminating the need for long charging times. In current battery swapping cabinets, if a battery abnormality is detected, such as overheating or combustion, the power is typically cut off, and a fire extinguishing device installed inside the cabinet is used to extinguish the fire.

[0004] However, when a battery malfunctions, it remains inside the battery compartment. If the fire extinguishing device cannot effectively stop the battery from burning, the battery may reignite, potentially damaging batteries and electrical control equipment in adjacent battery compartments, resulting in poor reliability of the battery swapping cabinet.

[0005] Chinese patent application CN202010373743.9 discloses a battery swapping cabinet. The cabinet includes: a cabinet body; a battery compartment with an openable and closable emergency opening on its rear face opposite the battery insertion end, allowing the battery to fall out; an explosion-proof compartment located within the cabinet body and below the battery compartment, with an explosion-proof opening at the bottom of the battery's fall path from the emergency opening; a battery condition acquisition unit; and a controller electrically connected to both the battery condition acquisition unit and the battery compartment, and used to control the emergency opening of the battery compartment to open when the battery condition value acquired by the acquisition unit exceeds a preset value, allowing the battery falling out of the emergency opening to enter the explosion-proof compartment through the explosion-proof opening.

[0006] However, when performing emergency battery operations, the aforementioned battery swapping cabinet directly drops the battery from the battery compartment into the explosion-proof compartment, posing a significant safety hazard. For example, batteries falling from a height already possess inherent dangers and can easily explode due to direct impact. Even if the battery falls into the explosion-proof compartment, there is still a large explosive impact that can damage the equipment. Summary of the Invention

[0007] To address the above problems, this invention provides an intelligent and safe battery swapping cabinet. Addressing the shortcomings of existing technologies, a receiving channel is installed between the battery compartment and the explosion-proof compartment. This allows the battery to slide from the battery compartment into the explosion-proof compartment via the receiving channel, avoiding strong impacts and reducing the risk factor. Furthermore, the additional extended melt-spraying component in this application, based on battery monitoring data from the battery condition acquisition unit, simultaneously performs fire-fighting and cooling treatment on both the battery compartment and the battery during the transfer from the battery compartment to the explosion-proof compartment, further enhancing the overall safety and reliability of the equipment.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A smart and safe battery swapping cabinet includes a swapping cabinet body, a battery compartment, and an explosion-proof compartment, characterized in that:

[0010] The battery compartment is tilted and placed on the battery swapping cabinet body. The battery compartment is used to house the battery. The battery compartment includes an outer compartment and an inner compartment. The outer compartment is fixedly connected to the battery swapping cabinet body. The inner compartment is slidably disposed relative to the outer compartment, and an emergency opening is provided at the rear of the inner compartment.

[0011] The explosion-proof compartment is installed on the rear side of the battery compartment. The explosion-proof compartment has an explosion-proof opening and an explosion-proof door. The explosion-proof compartment extends upward and is connected to a receiving channel. The receiving channel is inclined. After the inner compartment slides to connect with the receiving channel, the batteries in the inner compartment are transferred through an emergency opening into the receiving channel and slide down the slope into the explosion-proof compartment.

[0012] As an improvement, the inner sidewall of the outer compartment is provided with inwardly protruding guide strips, and the inner compartment is provided with corresponding slots that cooperate with the guide strips.

[0013] The battery is positioned and held in place within the inner compartment by the slot.

[0014] As an improvement, a fire-fighting solvent spraying assembly is installed on the top of the outer compartment, which sprays fire-fighting solvent downwards into the interior of the outer compartment.

[0015] As an improvement, an extended aerosol spraying assembly is provided at the bottom of the outer chamber. This extended aerosol spraying assembly expands as the inner chamber slides, spraying aerosol into both the outer and inner chambers respectively.

[0016] As an improvement, the extended aerosol spray assembly includes a fixed cavity, a movable cavity, and an aerosol propellant column;

[0017] The fixing cavity is fixedly installed at the bottom of the outer compartment;

[0018] The movable cavity is movably disposed on the fixed cavity, and the movable cavity is moved synchronously with the inner compartment;

[0019] The aerosol drug column is respectively disposed in the fixed cavity and the movable cavity, and a thermal initiator is disposed in the aerosol drug column.

[0020] As an improvement, the extended spray adhesive assembly is provided with a drive device that drives the movable cavity and the inner chamber to move synchronously. The drive device includes a drive motor, a lead screw, a lead screw nut, and a drive block.

[0021] The drive motor is disposed within the extended solvent spraying assembly, and the drive motor drives the lead screw to rotate.

[0022] The lead screw is arranged along the sliding direction of the inner chamber, and the lead screw nut is fitted on the lead screw;

[0023] The drive block is fixedly connected to the bottom of the inner compartment and the inner side wall of the inner compartment, respectively, and the lead screw nut is embedded in the drive block.

[0024] As an improvement, an emergency door is provided at the emergency opening of the inner compartment, and the emergency door is raised and lowered to open the emergency opening.

[0025] As an improvement, a receiving opening is provided at the connection point between the receiving channel and the emergency opening of the inner chamber. A sealing door is provided at the receiving opening, and the sealing door is opened synchronously with the emergency door.

[0026] As an improvement, the emergency door is provided with a magnetic metal strip facing the sealing door, and the sealing door is provided with a positioning groove that interlocks with and is magnetically attracted to the magnetic metal strip, and a magnet is provided in the positioning groove.

[0027] The sealing door has several round magnets evenly distributed on its surface, which are attracted to and resisted by the emergency door.

[0028] As an improvement, the sealing door is installed on the receiving channel via a lifting mechanism, which includes a lifting motor, a lifting screw, and a guide screw.

[0029] The lifting motor is located at the top of the explosion-proof compartment, and the lifting motor drives the lifting screw to rotate;

[0030] The lifting screw is arranged on one side of the material receiving channel along the conveying direction, and the sealing door is provided with a screw nut that corresponds to and cooperates with the lifting screw.

[0031] The guide screw is arranged parallel to the lifting screw on the other side of the receiving channel, and the sealing door is provided with a guide sleeve that corresponds to and cooperates with the guide screw.

[0032] The beneficial effects of this invention are as follows:

[0033] (1) By setting up a receiving channel between the battery compartment and the explosion-proof compartment, the present invention changes the existing direct drop method to allow the battery to slide from the battery compartment into the explosion-proof compartment through the receiving channel, thereby avoiding the strong impact caused by falling from a height, reducing the risk factor of battery transfer after combustion and high temperature, and ensuring the safety and reliability of the battery swapping cabinet equipment.

[0034] (2) The present invention, through the additional extended spray aerosol assembly, will spray aerosol on the battery compartment and the battery simultaneously during the process of transferring the battery from the battery compartment to the explosion-proof compartment based on the battery monitoring data collected by the battery condition acquisition unit. This will carry out fire-fighting and cooling treatment, eliminate potential hazards in the battery compartment and the battery, and further improve the overall safety and reliability of the equipment. It should be noted that during the fire-fighting and cooling treatment, the outer compartment and the inner compartment are separated before fire-fighting treatment. The outer compartment is equipped with a circuit structure for charging the battery in the inner compartment, which fully protects the structure of the outer compartment.

[0035] (3) When loading the battery into the inner compartment of the present invention, the battery is positioned and supported by the slots in the inner compartment, so that there is a certain space between the battery and the inner wall of the inner compartment. This allows the aerosol to quickly fill the inner compartment and surround the battery during fire fighting, so that the battery can be quickly and thoroughly fire fought.

[0036] (4) When the movable inner chamber is connected to the receiving channel, the present invention uses the synchronously moving movable cavity below to support the inner chamber and the battery, so as to avoid the weight of the inner chamber and the battery from damaging the stability of the inner chamber during the movement process. Furthermore, the support arm set on the receiving channel is interlocked with the slots on both sides of the inner chamber to further support the inner chamber and the battery and provide stability.

[0037] (5) The present invention uses a lifting mechanism to simultaneously move the sealing door and the emergency door, so that the two open at the same time, improving coordination and allowing the battery to be quickly transferred to the receiving channel along the inclined bottom of the inner compartment, with a tight connection.

[0038] In summary, this invention has advantages such as safety, reliability, and good stability, and is particularly suitable for the field of battery charging and discharging swapping cabinet technology. Attached Figure Description

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention 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 invention.

[0054] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0055] Example 1:

[0056] like Figures 1 to 11 As shown, an intelligent safety battery swapping cabinet includes a battery swapping cabinet body 1, a battery compartment 2, and an explosion-proof compartment 3. The battery compartment 2 is tilted on the battery swapping cabinet body 1 and is used to accommodate a battery 20. The battery compartment 2 includes an outer compartment 21 and an inner compartment 22. The outer compartment 21 is fixedly connected to the battery swapping cabinet body 1, and the inner compartment 22 is slidably disposed relative to the outer compartment 21. An emergency opening 221 is provided at the rear of the inner compartment 22.

[0057] The explosion-proof compartment 3 is installed on the rear side of the battery compartment 2. The explosion-proof compartment 3 is provided with an explosion-proof compartment opening 31, and an explosion-proof door 311 is provided on the explosion-proof compartment opening 31. The explosion-proof compartment 3 extends upward and is connected to a material receiving channel 32. The material receiving channel 32 is inclined. After the inner compartment 22 slides to connect with the material receiving channel 32, the battery 20 in the inner compartment 22 is transferred to the material receiving channel 32 through the emergency opening 221 and slides down the slope into the explosion-proof compartment 3.

[0058] It should be noted that the difference between this application and existing battery swapping cabinets is that this application can isolate the battery 20 that has triggered an alarm. Before isolation, the battery 20 is first subjected to fire suppression to ensure that the isolated battery 20 will not be at risk of combustion or explosion during the isolation process. Furthermore, this application involves an orderly sliding transfer of the battery 20 during the transfer process, rather than directly dropping the battery 20 out of the battery compartment 2. This application guides the battery 20 to prevent it from falling or being impacted during the isolation process. Once the battery 20 triggers an alarm signal, it indicates that there is already a safety hazard inside the battery 20, and it is essential to resolutely prevent the battery 20 from falling from a height and being impacted.

[0059] Furthermore, the battery swapping cabinet is also equipped with a temperature acquisition unit (not shown), a temperature adjustment unit 100, and a controller (not shown). Since the controller controls the temperature adjustment unit to cool or heat the battery compartment 2 based on the temperature acquired by the temperature acquisition unit, independent temperature control of each battery compartment 2 can be achieved, keeping the charging temperature of the battery 20 in the battery compartment 2 at a relatively constant state, thus ensuring the charging efficiency of the battery 20. The temperature adjustment unit 100 includes a cooling fan and an electric heating element.

[0060] Furthermore, the controller is electrically connected to the battery condition acquisition unit (not shown) and the battery compartment 2. When the battery condition value acquired by the battery condition acquisition unit exceeds the preset value, the controller controls the outer compartment 21 and the inner compartment 22 of the battery compartment 2 to start moving relative to each other, so that the inner compartment 22 is separated from the outer compartment 21 to ensure the safety of the outer compartment 21. At the same time, the emergency opening 221 on the inner compartment 22 opens, so that the battery 20 leaves the inner compartment 22 through the emergency opening 221 and enters the receiving channel 32.

[0061] The top of the battery swapping cabinet body 1 is equipped with a rain shelter 101, a 4G antenna module 102, and a speaker assembly 103.

[0062] The front of the battery compartment 2 is equipped with a door, which has an indicator light and a door lock.

[0063] Furthermore, a fire-fighting spraying solvent assembly 211 is provided on the top of the outer compartment 21, which sprays fire-fighting solvent into the outer compartment 21 from a downward direction.

[0064] A fire-fighting spray gel assembly 211 and a charger assembly 200 are installed at the top of the battery compartment 2. After the battery 20 alarms, the fire-fighting spray gel assembly 211 will fire the outer compartment 21 and the charger assembly 200 at the same time.

[0065] The fire-fighting spray aerosol assembly 211 is also composed of an aerosol propellant column and a thermal initiator, and its principle is similar to that of the extended spray aerosol assembly 212.

[0066] In addition, an extended aerosol spraying assembly 212 is provided at the bottom of the outer chamber 21. The extended aerosol spraying assembly 212 expands as the inner chamber 22 slides, and sprays aerosol into both the outer chamber 21 and the inner chamber 22 respectively.

[0067] Specifically, the extended aerosol spray assembly 212 includes a fixed cavity 213, a movable cavity 214, and an aerosol propellant column 215;

[0068] The fixed cavity 213 is fixedly installed at the bottom of the outer compartment 21;

[0069] The movable cavity 214 is movably disposed on the fixed cavity 213, and the movable cavity 214 is synchronously moved along with the inner compartment 22;

[0070] The aerosol propellant column 215 is respectively disposed in the fixed cavity 213 and the movable cavity 214. A thermal initiator is disposed in the aerosol propellant column 215. The thermal initiator has a thermal control line extending through the side wall of the box to the outside of the box. The thermal initiator is activated by the thermal control line and ignites the aerosol propellant column 215 to generate a large amount of aerosol material, which is sprayed out from the nozzle to realize automatic fire extinguishing of the outer compartment, inner compartment and battery.

[0071] The extended spray adhesive assembly 212 is provided with a drive device 4 that drives the movable cavity 214 and the inner chamber 22 to move synchronously. The drive device 4 includes a drive motor 41, a lead screw 42, a lead screw nut 43 and a drive block 44.

[0072] The drive motor 41 is disposed inside the extended spray adhesive assembly 212, and the drive motor 41 drives the lead screw 42 to rotate.

[0073] The lead screw 42 is arranged along the sliding direction of the inner chamber 22, and the lead screw nut 43 is fitted on the lead screw 42.

[0074] The drive block 44 is fixedly connected to the bottom of the inner compartment 22 and the inner side wall of the inner compartment 22 respectively, and the lead screw nut 43 is embedded in the drive block 44.

[0075] It should be noted that the difference between this application and the existing battery swapping cabinet is that this application also provides an extended spray adhesive assembly 212 that can move along with the inner compartment 22 of the battery compartment 2, so that when the inner compartment 22 moves and adjusts relative to the outer compartment 21, the movable cavity 214 can also move along with it, and the movable cavity 214 can support the inner compartment 22.

[0076] To further explain, the inner compartment 22 and the outer compartment 21 are staggered to ensure that the abnormal battery 20 in the inner compartment 22 will not affect the outer compartment 21, thus ensuring the normal operation of the charging components on the outer compartment 21.

[0077] The specific working process is as follows: when an abnormality is detected in the battery 20 inside the inner chamber 22, the drive motor 41 is controlled by the control component to operate. With the setting of the lead screw 42 and lead screw nut 43, the drive block 44 drives the inner chamber 22 and the movable chamber 214 to move backward synchronously. The inner chamber 22 is separated from the outer chamber 21, and the movable chamber 214 is located just below the inner chamber 22. The movable chamber 214 and the fixed chamber 213 are each equipped with a set of aerosol propellant columns 215. With the setting of the thermal initiator, the aerosol propellant columns 215 are quickly ignited to generate a large amount of aerosol material, which enters the outer chamber 21 and the inner chamber 22 respectively for fire fighting. At the same time, the inner chamber 22 also completes the contact docking with the receiving channel 32. After the fire fighting is completed, the battery 20 can be quickly transported into the explosion-proof chamber 3 through the receiving channel 32.

[0078] Example 2:

[0079] like Figure 6 As shown, the differences between Embodiment 2 and Embodiment 1 are described below:

[0080] The inner sidewall of the outer compartment 21 is provided with inwardly protruding guide strips 210, and the inner compartment 22 is provided with corresponding slots 220 that cooperate with the guide strips 210.

[0081] The battery 20 is supported and positioned within the inner compartment 22 by the slot 220.

[0082] It should be noted that when the outer compartment 21 and the inner compartment 22 move relative to each other, the guide protrusion 210 and the slot 220 cooperate to achieve the purpose of guidance. Due to the setting of the slot 220, a certain space is left between the battery 20 and the side wall of the inner compartment 22, so that the battery 20 can be well wrapped by aerosol during the fire treatment process, thus achieving the purpose of fire treatment.

[0083] In addition, when the inner chamber 22 moves, the receiving channel 32 is provided with a support arm 329 for interlocking and cooperating with the slot 220 to provide support.

[0084] Example 3:

[0085] like Figure 12 and Figure 13 As shown, the differences between Embodiment 3 and Embodiment 1 are described below:

[0086] An emergency door 222 is provided at the emergency opening 221 of the inner compartment 22, and the emergency door 222 is used to open and close the emergency opening 221.

[0087] Furthermore, a receiving opening 33 is provided at the junction of the receiving channel 32 and the emergency opening 221 of the inner chamber 22. A sealing door 34 is provided at the receiving opening 33, and the sealing door 34 is opened synchronously with the emergency door 222.

[0088] Furthermore, the emergency door 222 is provided with a magnetic metal strip 223 facing the sealing door 34, and the sealing door 34 is provided with a positioning groove 341 that intersects and magnetically attracts the magnetic metal strip 223, and a magnet is provided in the positioning groove 341.

[0089] The sealing door 34 has a number of round magnets 342 evenly distributed on its surface, which are attracted to and resisted by the emergency door 222.

[0090] Specifically, the sealing door 34 is installed on the receiving channel 32 via a lifting mechanism 5, which includes a lifting motor 51, a lifting screw 52, ​​and a guide screw 53.

[0091] The lifting motor 51 is located on the top of the explosion-proof chamber 3, and the lifting motor 51 drives the lifting screw 52 to rotate.

[0092] The lifting screw 52 is arranged on one side of the material receiving channel 32 along the conveying direction, and the sealing door 34 is provided with a screw nut that corresponds to and cooperates with the lifting screw 52.

[0093] The guide screw 53 is arranged parallel to the lifting screw 52 on the other side of the receiving channel 32, and the sealing door 34 is provided with a guide sleeve that corresponds to and cooperates with the guide screw 53.

[0094] To ensure seamless connection, when setting the sealing door 34 and emergency door 222 on the receiving channel 32, the lifting mechanism 5 is used to drive them simultaneously, so that the emergency opening 221 and the receiving opening 33 open at the same time. Then, the battery 20 can slide along the inclined bottom of the inner chamber 22 into the receiving channel 32. The battery 20 then slides along the receiving channel 32 into the explosion-proof chamber 3. The explosion-proof door 311 on the explosion-proof chamber 3 seals the explosion-proof chamber opening 31 to isolate the abnormal battery 2.

[0095] In the specific operation process, after the inner chamber 22 is connected to the receiving channel 32, the sealing door 34 is connected to the emergency door 222. The sealing door 34 and the emergency door 222 are magnetically connected to form an integral connection. Then, the lifting motor 51 drives the lifting screw 52 to rotate, and with the screw nut, the sealing door 34 is lifted and opened. At the same time, the emergency door 222 is also lifted and opened. Then, the battery 20 is fed into the receiving channel 32 along the inclined bottom of the inner chamber 22. After that, the sealing door 34 and the emergency door 222 are reset, the inner chamber 22 is reset, and it is combined with the outer chamber 21 to form the battery compartment 2.

[0096] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
