Description

Technical Field

[0001] This invention relates to the field of charging and swapping energy storage cabinet technology, specifically a car charging and swapping energy storage cabinet with a canopy structure. Background Technology

[0002] With the rapid development of the new energy vehicle industry and the continuous increase in the number of electric vehicles, users' demand for energy replenishment efficiency is constantly rising. Battery swapping, with its advantages of fast replenishment speed, standardized battery life management, and minimal impact on the power grid, has become an important component of the new energy vehicle energy replenishment system. As the core equipment of the battery swapping model, the charging, swapping, and energy storage cabinet is a standardized outdoor device integrating battery energy storage, rapid battery swapping, intelligent charging, energy dispatching, and safety protection. It primarily provides fast and convenient battery replacement services for new energy vehicles and is widely used in outdoor scenarios such as battery swapping stations, parking lots, highway service areas, and industrial parks.

[0003] Currently, outdoor charging and swapping energy storage cabinets have revealed numerous safety hazards and technical defects in rainy weather conditions during practical applications, as follows: When swapping batteries in rainy weather, the surface of the battery pack to be charged removed from the vehicle will be covered with a large amount of rainwater and water droplets. When it is directly placed into the battery compartment for charging, the large amount of moisture remaining on the circumferential side of the battery pack will increase the humidity inside the battery compartment, thereby accelerating the corrosion of the metal structure and electrical components inside the compartment. The moisture remaining on the charging side of the battery pack will enter the charging docking area, which can easily cause safety accidents such as short circuits and leakage at the charging interface, thus significantly shortening the service life of the equipment. In addition, some existing technologies only use simple ventilation structures for dehumidification, which cannot complete multi-face simultaneous water removal during the battery pack docking process. The water removal efficiency is low, the blind spot is large, and it cannot effectively remove the water droplets attached to the end face and side wall of the battery pack. The existing battery compartments of charging and swapping energy storage cabinets mostly adopt a single compartment structure. After the battery pack is put into the compartment, there is no precise centering and positioning mechanism. The battery pack is prone to placement deviation, which leads to the charging interface and charging end not being able to accurately connect, resulting in problems such as wear and tear, loose connection and overheating. The charging docking area of ​​the existing equipment lacks a graded protection structure and relies solely on the compartment door for overall sealing. In addition to the water splashing during the water removal process, water droplets and condensed water vapor inside the compartment can easily enter the docking area. It is impossible to form an independent sealed protective space for the interface plug during the charging process, resulting in insufficient insulation protection performance. Summary of the Invention

[0012] As a preferred embodiment of the charging and swapping energy storage cabinet of the present invention, the docking protection mechanism includes a frame fixed on the end face of the inner cavity of the outer compartment, an end head fixedly provided inside the frame, trapezoidal blocks movably penetrating the top and bottom of the frame, and a cover frame fixedly provided on the top and bottom surfaces of the frame, and movable plates slidably sleeved inside the corresponding cover frames fixedly provided on opposite ends of the two trapezoidal blocks, and straight springs fixedly connected between the opposite sides of the two movable plates and the outer side of the frame.

[0013] As a preferred embodiment of the charging and swapping energy storage cabinet of the present invention, the docking protection mechanism further includes an L-shaped frame integrally formed on both sides of the opening end of the frame, two sealing doors are slidably installed between the two L-shaped frames, a protruding plate is fixedly provided on the outer side of the sealing door at the upper end, and an opening and closing component for driving the two sealing doors to open and close is also fixedly installed on the outer side of the frame. The opening and closing assembly includes guide grooves formed on two L-shaped frames. Two side frames are fixedly provided in the middle of the opposite side of the two L-shaped frames. A toothed disc is rotatably installed between the two side frames on the same side. L-shaped toothed plates are fixedly connected to the opposite ends of the two sealing doors.

[0014] As a preferred embodiment of the charging and swapping energy storage cabinet of the present invention, the door is hollow, an air inlet slot is provided on the outer side of the door junction, an air duct is provided on the cabinet body, and an air outlet slot connected to the air duct is provided on the cabinet body at the position corresponding to each battery compartment, an air outlet hole is provided on one side of the door, and an exhaust hole is provided at one end of the outer compartment where the frame is installed.

[0015] The beneficial effects of this invention are: 1. This invention can use pushers that lift the battery pack from four sides simultaneously to press the corresponding sides of the battery pack, thereby lifting the battery pack to the center position and ensuring that the charging interface on the battery pack is aligned with the charging head inside the battery compartment. At the same time, the lifted battery pack will form a ventilation channel with the inner compartment, expanding the heat dissipation surface and improving heat dissipation performance. 2. During the process of using the synchronously rotating rollers on all four sides to push the battery pack closer to the end, the present invention uses four water removal units installed on the inner compartment to blow away the rainwater attached to the end face and four sides of the battery pack, and guides and drains the water droplets that fall during the blowing process, so as to reduce the water content inside the battery compartment, thereby reducing the generation of water vapor during the charging process, avoiding damage to the electrical components inside the battery compartment in a high humidity environment, and improving the service life of the equipment. 3. This invention uses two closed upper and lower doors in the initial state to seal the opening end of the enclosure, which can effectively prevent water droplets splashed up during the purging and dewatering process from falling into the end of the enclosure, thus reducing the occurrence of charging failures. 4. This invention utilizes a U-shaped rod that swings synchronously with the swing bar to contact the convex plate, thereby causing the convex plate to move upward. This causes the L-shaped toothed plate at the upper end to move upward synchronously with the upper sealing door. Under the meshing action of the toothed disc, the L-shaped toothed plate at the lower end will drive the lower sealing door to move downward, thus controlling the two sealing doors to open in opposite directions. This ensures that the charging interface of the battery pack can be smoothly inserted into the frame and connected to the end. 5. In the process of pushing the battery pack and inserting it into the end, the present invention can use the pushed battery pack to make the two trapezoidal blocks move in opposite directions, and the two movable plates that move in opposite directions can compress the gas inside the cavity on the opposite side, so that the gas is discharged from the corresponding exhaust pipe into the square ring groove, causing the elastic airbag cloth to inflate and seal the gap formed between the battery pack and the frame, preventing water vapor from entering the docking area during the charging process. 6. After the compartment door is closed, the air inlet slot on the compartment door junction is aligned with the air outlet slot of the ventilation duct, allowing the air inside the duct to enter the hollow cavity of the compartment door and then be blown out through the air outlet to the vicinity of the battery pack. The air carries the heat around the battery pack and is discharged through the exhaust port. At the same time, a small amount of water droplets remaining on the surface of the battery pack will turn into water vapor during the rising process and be blown out along with the airflow used for heat dissipation, thereby achieving the purpose of accelerating heat dissipation and dehumidification.

[0019] 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.

[0020] The charging and swapping energy storage cabinet of the present invention is a part of the energy supply device and is a type of integrated charging and swapping equipment. It is used to provide fast and convenient battery replacement services for new energy vehicles and solves the problem that water remaining on the surface of the battery pack affects the charging safety and equipment lifespan when charging in rainy weather in traditional charging and swapping energy storage cabinets. Example

[0021] Refer to the instruction manual appendix Figures 1-2 and Figure 9This embodiment is the first embodiment of the present invention, providing a car charging and swapping energy storage cabinet with a canopy structure. The charging and swapping energy storage cabinet includes a cabinet body 1 and a canopy 2 installed on the top of the cabinet body 1. The canopy 2 completely covers the battery swapping operation area in front of the cabinet body 1, effectively providing rain protection for users during battery swapping operations in rainy weather. A monitoring probe is installed under the canopy 2, which is electrically connected to the main control unit built into the cabinet body 1. It can collect the battery swapping operation screen and equipment operating status in real time, realizing early warning and tracing of abnormal situations. At the same time, the top of the canopy 2 has reserved photovoltaic module installation positions, which can be matched to install monocrystalline silicon solar panels. The solar panels are electrically connected to the energy storage battery and power supply module inside the cabinet body 1 through a photovoltaic controller. On sunny days, photovoltaic power generation can directly supply the cabinet load operation and battery replenishment, reducing the electricity drawn from the municipal power grid and achieving energy saving and consumption reduction. At the same time, it can provide backup power for the core control system and emergency lighting of the equipment in emergency situations such as municipal power outages, line maintenance, and sudden power outages, avoiding complete equipment shutdown and improving the emergency support capability of the equipment.

[0022] The front of the cabinet 1 has multiple battery compartments 3. Each battery compartment 3 includes an outer compartment 31, an inner compartment 32, and a door 33 installed on the front of the cabinet 1 to seal the battery compartment 3. The upper and lower ends of the door 33 are fixed with round rods, which are rotatably connected to the cabinet 1. The door 33 has an electronic door lock, which is electrically connected to the main control unit and can be unlocked by scanning a code, swiping a card, or remote control. The inner compartment 32 is fixedly installed inside the outer compartment 31, and the two are concentrically arranged. The inner cavity size of the inner compartment 32 matches the outer size of the battery pack to be charged, forming a space for accommodating and guiding the battery pack. The concentric arrangement between the inner compartment 32 and the outer compartment 31 can form a heat dissipation channel between the inner compartment 32 and the outer compartment 31, improving the heat dissipation of the battery pack during charging.

[0023] The battery compartment 3 also includes a positioning mechanism 34 installed between the inner compartment 32 and the outer compartment 31. The positioning mechanism 34 is used to perform four-way synchronous position adjustment and centering calibration of the inserted battery pack. The inner compartment 32 is provided with a water removal mechanism 37 at the end away from the compartment door 33. The water removal mechanism 37 is used to perform multi-face synchronous blowing and water removal of water droplets adhering to the surface of the battery pack during rainy weather. The bottom of the inner compartment 32 is also provided with a drainage component to guide, collect and discharge the accumulated water dripping from the blowing into the compartment.

[0024] It should be noted that when the battery pack to be charged is placed inside the cabinet 1 for charging in rainy weather, the main control unit will first use the positioning mechanism 34 to adjust the position of the placed battery pack in four directions synchronously so that the charging interface on the battery pack is aligned with the charging head inside the battery compartment 3. Then, during the process of driving the battery pack to feed towards the charging head to complete the insertion, the water removal mechanism 37 is activated simultaneously to thoroughly blow away and clean the rainwater adhering to the surface of the battery pack. At the same time, the drainage component drains the accumulated water out of the compartment, reducing the moisture content inside the compartment from the source and reducing the charging safety risk.

[0025] Furthermore, such as Figure 2 and Figures 4-5 As shown, the positioning mechanism 34 includes end lugs 341 fixed at both ends of the four sides of the inner cavity of the outer compartment 31 and intermediate lugs 343 fixed in the middle of the inner cavity of the outer compartment 31. The intermediate lug 343 is composed of drive seats and guide seats arranged alternately in sequence. The drive seats are installed in the middle of the four sides of the inner cavity of the outer compartment 31, and the guide seats are installed in the middle of the four corners of the inner cavity of the outer compartment 31. The alternating drive seats and guide seats form a rectangular transmission part. A gear is rotatably mounted in the middle of each drive seat and guide seat. Multiple gears are connected by a gear chain 344. A stud 342 is rotatably mounted between two end lugs 341 located on the same side. One end of the column 342 is connected to the drive motor fixedly mounted on the corresponding end ear 341 via a coupling. The drive motor is a servo motor with an encoder (model R380) and is electrically connected to the main control unit, which can achieve precise speed and angle control. The gear mounted on the drive seat is fixedly sleeved on the outside of the corresponding stud 342. The threads at both ends of the stud 342 are set in opposite directions to form a bidirectional screw structure. Two sets of slide rails 345 are installed in the middle of the four sides of the inner cavity of the outer chamber 31. The two single rails in each set are set in a U-shape. The two sets of slide rails 345 are placed on both sides of the corresponding drive seat. A pusher 346 is slidably installed between the two sets of slide rails 345.

[0026] Furthermore, the pusher 346 includes a slide block 3461 slidably mounted on the corresponding slide rail 345. Two slide blocks 3461 located on the same side are respectively threaded onto the outer ends of the corresponding studs 342. A pusher 3462 is provided between the two slide blocks 3461. A swing arm 3463 is hinged between both ends of the pusher 3462 and the corresponding slide block 3461. A rotating roller 3464 for driving the battery pack feed is rotatably mounted on the side of the pusher 3462 facing the inner compartment 32. Multiple rotating rollers 3464 are provided on each pusher 3462 and are driven to rotate by a power unit installed on the outer side of the corresponding pusher 3462. The power unit adopts a micro geared motor and is electrically connected to the main control unit. A through slot 38 for the pusher 3462 to pass through is opened in the middle of the four sides of the inner compartment 32. The length of the through slot 38 matches the stroke of the pusher 3462.

[0027] It should be noted that during the process of adjusting the position of the battery pack placed inside the battery compartment 3, the corresponding stud 342 is rotated by a drive motor. The rotation of the stud 342 drives multiple gears mounted on the intermediate lug 343 to rotate synchronously via the gear chain 344, thereby driving the rotation of the other three studs 342. During the synchronous rotation of the four studs 342, the slides 3461 sleeved at both ends of the same stud 342 will move relative to each other, causing the angle between the pusher 3462 and the swing arm 3463 to gradually increase. During this process, the pusher 3462 will move with the swing arm 3463. The angle change gradually lifts the battery pack, allowing the four pushers 3462 to simultaneously pass through the corresponding slots 38, pushing the battery pack to the center position. This ensures that the charging port on the battery pack is aligned with the charging head inside the battery compartment 3, eliminating insertion deviation. The lifted battery pack also forms a ventilation channel with the inner compartment 32 to improve heat dissipation. Once the battery pack position is adjusted, the main control unit controls the rollers 3464 on the four pushers 3462 to rotate synchronously. Utilizing the friction between the synchronously rotating rollers 3464 and the sidewalls of the battery pack, the battery pack is smoothly fed towards the charging head until the insertion and docking are completed.

[0028] Furthermore, such as Figure 3 and Figure 9-10 As shown, the water removal mechanism 37 includes a water removal assembly 371, which consists of four water removal units. These four units are respectively installed at one end of the center of the four sides of the inner cavity 32. The water removal units on the left and right sides are symmetrically arranged, while the water removal units on the upper and lower sides are staggered. Specifically, in the direction where the battery pack is pushed in and inserted, the upper water removal unit is positioned further forward than the lower water removal unit. This upper unit can be used to first blow away the water adhering to the rear end surface of the battery pack. Subsequently, the lower water removal unit can remove the water that flowed during the blowing process by the upper and left / right water removal units. The water on the lower surface of the battery pack is thoroughly blown away. Each water removal unit includes two support cylinders 3711 fixed on the side wall of the inner chamber 32. An exhaust duct 3712 is fixedly connected between the two support cylinders 3711. An air outlet 3713 is opened on the surface of the exhaust duct 3712. The angle between the air blown out of the air outlet 3713 and the horizontal plane of the battery pack feeding direction is 30°. The water droplets on the surface of the battery pack are blown away towards the opening of the outer chamber 31 by the inclined airflow, so as to prevent the water droplets from flowing towards the charging docking area. At the same time, it can improve the coverage area and impact force of the blowing, and enhance the water removal effect.

[0029] Furthermore, the dewatering mechanism 37 also includes an air source assembly 372, which includes an air pump 3721 (model STA02) fixed to the outer end of the outer chamber 31. The air pump 3721 is an oil-free silent air pump with a rated outlet pressure of not less than 0.4MPa. It is electrically connected to the main control unit and can achieve precise control of start-up, shutdown and outlet pressure. Both outlet ends of the air pump 3721 are connected to a main pipe 3722, and the ends of the two main pipes 3722 are connected to U-shaped branch pipes 3723. The air source assembly 372 also includes hollow L-shaped plates fixed at the four corners of the outer side of the inner chamber 32. Each L-shaped plate is connected to the end of the corresponding U-shaped branch pipe 3723 and two adjacent support cylinders 3711 to form a closed-loop air supply path, ensuring that the outlets 3713 of the four dewatering units can discharge air synchronously and ensuring the uniformity of the purging pressure. Furthermore, the water removal mechanism 37 also includes a cover opening assembly 373. The cover opening assembly 373 includes two swing bars 3731 hinged to the top of the inner side of the inner compartment 32. A rotating drum 3732 is rotatably installed between one end of the two swing bars 3731. The rotating drum 3732 is also covered with a layer of absorbent cotton on its circumferential side to further absorb water stains remaining on the end face of the battery pack charging interface after blowing, thus achieving physical secondary water removal. Each of the two swing bars 3731 is fixedly provided with an arc rod 3734 that moves through the top of the inner compartment 32. An arc spring 3735 is sleeved on the outside of the arc rod 3734. A ball head is fixedly provided at one end of the arc rod 3734 that passes through the inner compartment 32. The diameter of the ball head is larger than the diameter of the arc rod, so as to prevent the arc rod 3734 from slipping under the action of the arc spring 3735 and ensure the stability of the structure operation.

[0030] It should be noted that during the process of using the synchronously rotating rollers 3464 on the four-sided pusher 3462 to push the battery pack closer to the charging head, firstly, the airflow blown by the water removal unit set at the front of the upper side contacts the upper end of the rear end face of the battery pack being pushed, causing the water attached to the rear end face to flow downward to the lower side of the battery pack under the action of the airflow or to drip directly after accumulating. Then, after the airflow blown by the water removal units on the left and right sides contacts the side where the battery pack is being pushed, it will blow the water together, and after it gathers to a certain extent, it will flow to the lower end face of the battery pack and drip. Then, after the airflow blown by the water removal unit located on the lower side contacts the lower surface of the battery pack being pushed, it will also blow the water together, and after it gathers to a certain extent, it will drip directly. In addition, in order to prevent the dripping water from accumulating on the upper surface of the lower pusher 3462, the upper surface of the lower pusher 3462 can be provided with an arc surface structure. The arc surface structure will not affect the installation of the corresponding rollers 3464, that is, the multiple rollers 3464 after installation are arranged horizontally and coplanarly. When the battery pack end face is fed to contact the rotating drum 3732 after being blown, since the swing bar 3731 is initially set at an angle, the battery pack will push the rotating drum 3732 to feed and cause the swing bar 3731 to swing, thus squeezing the arc spring 3735. During this process, the rotating drum 3732 will be tightly attached to the end face of the battery pack under the action of the arc spring 3735, and will rotate as the swing bar 3731 swings, so as to better absorb the water stains remaining on the end face of the battery pack after blowing, and further enhance the water removal effect.

[0031] It should be noted that the battery pack feeding and dewatering processes described above are all started after the compartment door 33 is closed. That is, after the main control unit detects that the compartment door 33 is completely closed and locked, it simultaneously starts the drive motors of the air pump 3721 and the positioning mechanism 34. The stopping of the air pump 3721 is controlled by the main control unit. After detecting that the charging interface on the battery pack has been connected with the charging terminal inside the battery compartment 3, it immediately sends a command to stop the air pump 3721 and completes the entire dewatering process.

[0032] Furthermore, such as Figure 2 As shown, a U-shaped drainage channel 35 is provided on the bottom inner side of the inner compartment 32, and water guiding arc plates 39 are fixed on both sides of the corresponding through slot 38 on the bottom inner side of the inner compartment 32. The drainage channel 35 is inclined downward towards the opening of the outer compartment 31, with an inclination angle of not less than 3°, to ensure that the accumulated water can flow smoothly under the action of gravity. A drainage pipe 310 connected to the low end of the drainage channel 35 is fixed on the bottom outer side of the inner compartment 32. The bottom end face of the inner cavity of the outer compartment 31 is also designed to be inclined downward towards the drainage pipe 310, so as to guide the water that drips directly onto the bottom end face of the outer compartment 31 to converge with the water discharged from the drainage pipe 310 and then be discharged from the battery compartment 3.

[0033] Among them, the way to drain the accumulated water from the battery compartment 3 after the convergence can be selected according to the installation scenario: Option 1, a sealed water storage tank is set at the bottom of the inner side of the outer compartment 31 to collect water. The water storage tank has a built-in liquid level sensor that is electrically connected to the main control unit. When the accumulated water reaches the set liquid level, an alarm signal is sent, and the maintenance staff can manually open the drain valve to drain the water. Option 2, the drain pipe 310 is connected to an external water inlet pipe. The water inlet pipes of all battery compartments are connected to the main drain pipe at the bottom of the cabinet 1, which directly guides the water out to the drainage system outside the cabinet, realizing maintenance-free automatic drainage.

[0034] It should be noted that during the water removal process using the four water removal units, a small portion of the dripping water will fall through the groove 38 on the lower end face of the inner chamber 32 to the bottom of the inner cavity of the outer chamber 31, while most of the water will drip directly into the inner chamber 32 and, guided by the water guide arc plate 39, be discharged into the drainage trough 35, and finally be collected and discharged. Example

[0035] Refer to the instruction manual appendix Figure 4 and Figures 6-9 This embodiment is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the outer compartment 31 is also provided with a docking protection mechanism 36 for separating the docking area corresponding to the charging process.

[0036] Furthermore, the docking protection mechanism 36 includes a frame 361 fixed to the inner end face of the outer cavity 31. An end 362 is fixedly provided inside the frame 361, which is directly opposite the charging interface on the battery pack after the position adjustment is completed. Trapezoidal blocks 3611 are movably provided through the top and bottom of the frame 361, and a cover frame 363 is fixedly provided on the top and bottom surfaces of the frame 361. Movable plates 364 are fixedly provided at opposite ends of the two trapezoidal blocks 3611 and are slidably sleeved inside the corresponding cover frame 363. A sealing ring is covered on the outside of the movable plate 364 to seal the cavity formed between the movable plate 364 and the corresponding cover frame 363. Straight springs 365 are fixedly connected between the opposite sides of the two movable plates 364 and the outside of the frame 361 to provide a reset spring force for the trapezoidal blocks 3611. Furthermore, a square annular groove is provided at the opening end of the inner side of the frame 361, and an elastic airbag cloth is fixed at the opening of the square annular groove. Both covers 363 are connected to an exhaust pipe 366 that is connected to the square annular groove on one side. Heat-conducting columns 3612 are fixed on both sides of the frame 361, and the opposite ends of the heat-conducting columns 3612 on both sides extend into the inside of the frame 361. This can better guide the heat generated at the joint to the outside of the frame 361, avoid heat accumulation and temperature rise in the docking area, and improve charging stability. When the straight spring 365 is in the natural rebound state, the inclined surface of the trapezoidal block 3611 extends into the inner side of the frame 361, and the airbag cloth is just retracted inside the square annular groove, which does not affect the insertion of the battery pack charging interface.

[0037] It should be noted that during the process of pushing the battery pack and inserting it into the end 362 (i.e., the aforementioned charging head), the advancing battery pack will simultaneously squeeze the upper and lower trapezoidal blocks 3611, causing them to move in opposite directions and stretching the corresponding straight spring 365. The moving plate 364, which moves in opposite directions, will compress the gas inside the cavity on its opposite side, causing it to be discharged from the corresponding exhaust pipe 366 into the square annular groove. The elastic airbag cloth will quickly inflate as the air pressure in the inflation chamber increases, filling the gap between the battery pack end face and the frame 361, sealing the gap between the battery pack and the frame 361 around the entire circumference, forming an independent sealed space in the docking area, completely preventing moisture from entering the docking area, and ensuring the insulation performance and operational safety of the charging interface.

[0038] Furthermore, such as Figure 4 and Figures 6-8As shown, the docking protection mechanism 36 also includes L-shaped frames 367 integrally formed on both sides of the opening end of the frame 361. Two sealing doors 368 are slidably installed between the two L-shaped frames 367. A protruding plate 3610 is fixedly provided on the outer side of the upper sealing door 368. A U-shaped rod 3733 is fixedly provided between one side of the two swing bars 3731. The U-shaped rod 3733 moves synchronously with the swing bars 3731 to trigger the opening of the sealing doors of the docking protection mechanism 36. An opening and closing assembly 369 for driving the two sealing doors 368 to open and close is also fixedly installed on the outer side of the frame 361. The protruding plate 3610 is located on the movement trajectory of the U-shaped rod 3733 as it swings with the swing bars 3731, so as to use the swinging U-shaped rod 3733 to control the opening of the two sealing doors 368.

[0039] Furthermore, the opening and closing assembly 369 includes guide grooves 3691 formed on two L-shaped frames 367. Two side frames 3692 are fixedly provided in the middle of the opposite side of the two L-shaped frames 367. A toothed disc is rotatably installed between the two side frames 3692 on the same side. L-shaped toothed plates 3693 are fixedly connected to the opposite ends of the two sealing doors 368. The two L-shaped toothed plates 3693 on the same side are always in a meshing state with the corresponding toothed disc. The L-shaped toothed plate 3693 located at the upper end (i.e., fixedly connected to the upper sealing door 368) has a vertical through hole for the lower L-shaped toothed plate 3693 to pass through and two limiting grooves 3694. The lower L-shaped toothed plate 3693 is set with a U-shaped structure at the end near the corresponding sealing door 368, and the U-shaped end of the lower L-shaped toothed plate 3693 is slidably connected to the inside of the two limiting grooves 3694.

[0040] It should be noted that the two sealing doors 368 are initially closed, which can effectively prevent water droplets splashed during the water removal process from entering the end 362 inside the frame 361. During the process of pushing the battery pack to be inserted into the end 362, the U-shaped rod 3733, which swings synchronously with the swing bar 3731, will contact the convex plate 3610 and push the convex plate 3610 to continue to move upward. This will drive the L-shaped toothed plate 3693 at the upper end to move upward synchronously with the sealing door 368. Under the meshing action of the toothed plate, the L-shaped toothed plate 3693 at the lower end will drive the sealing door 368 at the lower end to move downward. This achieves the control of the two sealing doors 368 to open in opposite directions, ensuring that the charging interface of the battery pack can be smoothly inserted into the frame 361 and connected to the end 362. Example

[0041] Refer to the instruction manual appendix Figures 2-3 and Figures 11-12This embodiment is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the door 33 is hollow, and an air inlet slot 6 is provided on the outer side of the door 33 transition end. An air duct 4 is provided on the cabinet body 1, and an air outlet slot 5 connected to the air duct 4 is provided on the cabinet body 1 at the position corresponding to each battery compartment 3. When the door 33 is completely closed, the air inlet slot 6 on the door 33 transition end is connected to the air outlet slot 5 of the air duct 4. An air outlet is provided on one side of the door 33, and an exhaust hole is provided at one end of the outer compartment 31 where the frame 361 is installed. The exhaust hole is connected to the outside of the cabinet body 1. The above structures together constitute a heat dissipation and dehumidification linkage component, which can realize continuous heat dissipation and small amount of water vapor discharge inside the battery compartment 3 during charging.

[0042] It should be noted that during the heat dissipation process of the battery pack during charging, the battery pack to be charged is placed inside the battery compartment 3 and the compartment door 33 is closed. This allows the air inside the air duct 4 to enter the hollow cavity of the compartment door 33 and then blown out through the air outlet to the vicinity of the battery pack, carrying the heat around the battery pack and dissipating it through the exhaust vent. Conversely, when the compartment door 33 is opened, because the air inlet slot 6 and the air outlet slot 5 are misaligned, the airflow inside the air duct 4 cannot be discharged, and the heat dissipation and dehumidification components automatically stop working. This effectively prevents external humid air from entering the compartment through the air duct, preventing the components inside the compartment from getting damp and improving the protective performance of the equipment.

[0043] The working principle of the above-mentioned charging and swapping energy storage cabinet is as follows: When charging the battery pack on a rainy day, firstly, scan the code to open the door 33 of the fully charged battery compartment 3, take out the fully charged battery pack, and place the battery pack to be charged between the upper ends of the two water guide arc plates 39 on the inner side of the inner compartment 32. Then, the door 33 is closed. Then, the control terminal controls the stud 342 to rotate, so that the four pushers 3462 are gradually lifted up as the angle of the corresponding swing arm 3463 changes, and synchronously pass through the corresponding through slot 38. Then, the rotating roller 3464 on the pusher 3462 presses against the corresponding side of the battery pack, so as to lift the battery pack to the center position and ensure that the charging interface on the battery pack is aligned with the charging head inside the battery compartment 3. Then, drive the rotating roller 3464 on the four pushers 3462 to rotate, and use the rotating roller 3464 that rotates synchronously on the four sides to push the battery pack closer to the charging head. When the advancing battery pack enters the dewatering area, the airflow from the dewatering unit located at the front of the upper side contacts the upper end of the rear face of the advancing battery pack, causing the water adhering to the rear face to flow downwards to the lower side of the battery pack under the action of the airflow or to drip directly after accumulation. The airflow from the dewatering units on the left and right sides contacts the side of the advancing battery pack, blowing the water together. After it gathers to a certain extent, it flows to the lower end face of the battery pack and drips. Then, the airflow from the dewatering unit located on the lower side contacts the lower surface of the advancing battery pack, also blowing the water together. After it gathers to a certain extent, it drips directly. The water that drips is swept away by the dewatering mechanism 37 and guided back to a place for collection or directly discharged. When the battery pack end face, after being purged, contacts the rotating drum 3732, the continued advancement of the battery pack will push the rotating drum 3732 to advance, causing the swing bar 3731 to swing and compress the arc spring 3735. The U-shaped rod 3733, which swings synchronously with the swing bar 3731, will contact the convex plate 3610 and push the convex plate 3610 to move upward, thereby driving the L-shaped toothed plate 3693 located at the upper end to move upward synchronously with the sealing door 368 on the upper side. Under the meshing action of the toothed disc, the L-shaped toothed plate 3693 located at the lower end will drive the lower side... The sealing door 368 moves down, thereby controlling the two sealing doors 368 to open in opposite directions. The battery pack continues to be pushed into the frame 361. During the process of the battery pack being pushed in, it will squeeze the two trapezoidal blocks 3611 to move in opposite directions. The movable plate 364 that moves in opposite directions will compress the gas in the cavity on the opposite side, so that it will be discharged from the corresponding exhaust pipe 366 into the square ring groove. The elastic airbag cloth will bulge as the gas in the square groove increases, sealing the gap formed between the battery pack and the frame 361. Once the charging port on the battery pack is connected to the end 362 inside the frame 361, the charging process begins. During this time, after the door 33 is closed, the heat dissipation and dehumidification components will blow out the heat inside the battery compartment 3. At the same time, any remaining water droplets on the surface of the battery pack will turn into water vapor as the battery compartment 3 heats up and be blown out along with the airflow used for heat dissipation.
