Description

Technical Field

[0001] The present invention relates to the field of battery replacement for electric vehicles, and in particular to a battery replacement station or energy storage station for a battery replacement panel, a battery replacement panel combination unit, and an energy replacement station or an energy storage station. Background Art

[0002] New energy vehicles are becoming more and more popular among consumers. The energy used by new energy vehicles is basically electricity. New energy vehicles need to be charged after the electricity is used up. Due to the limitations of current battery technology and charging technology, it takes a long time to fully charge new energy vehicles, which is not as simple and fast as refueling cars directly. Therefore, in order to reduce the waiting time of users, replacing the battery when the power of new energy vehicles is running out is an effective means. In order to facilitate battery replacement and meet the battery replacement needs of more and more new energy vehicles, it is necessary to build battery replacement stations or energy storage stations.

[0003] Since battery swap stations and energy storage stations are generally set up in the open air and are equipped with a large number of battery packs and electrical equipment for charging the battery packs, the waterproof performance of battery swap stations and energy storage stations is particularly critical to avoid failures of battery packs and electrical equipment inside the battery swap stations and energy storage stations. Solar energy and other equipment are usually installed outside the battery swap station or energy storage station to provide power for the battery swap station or energy storage station. The equipment is generally fixed to the top plate of the battery swap station or energy storage station through fixings. Therefore, in order to enhance the waterproof performance of the battery swap station or energy storage station, it is also necessary to prevent rainwater and other liquids from penetrating into the interior of the battery swap station or energy storage station through the connection between the equipment and the top plate of the battery swap station or energy storage station, thereby preventing rainwater and other liquids from penetrating from the installation gap of the battery swap station or energy storage station into the interior of the battery swap station or energy storage station and causing equipment failure. The patent with application number CN203188396U discloses a sandwich-structured insulation board, including two layers of panels, an insulation layer sandwiched between the two layers of panels, a plurality of through holes in the insulation layer, and connecting columns with two ends fixedly connected to the two layers of panels respectively inserted in the through holes, the two layers of panels and the connecting columns are made of inorganic gelling materials, and the insulation layer is made of XPS board, EPS board, polyurethane or phenolic material. The patent with application number CN211313108U discloses a mounting structure for bakelite corrugated board, including a bakelite corrugated board body, a first folding part is integrally formed on the left side of the bakelite corrugated board body, and a first mounting through hole arranged at an equal distance is opened on the top of the first folding part, and a second folding part is integrally formed on the right side of the bakelite corrugated board body, and a second mounting through hole arranged at an equal distance is opened on the top of the second folding part. When installed, the second folding part covers the first folding part. The sandwich insulation board or bakelite corrugated board structure in the above-mentioned prior art cannot meet the requirements of taking into account the overall strength and waterproof sealing performance of the battery swap station or energy storage station. Summary of the invention

[0004] The technical problem to be solved by the present invention is to improve the overall strength and waterproof sealing performance of a battery swap station, and to provide a storage panel, a storage panel combination unit, and a battery swap station or energy storage station.

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

[0007] In this solution, a column is provided between the first layer and the second layer to improve the strength of the panel while connecting other equipment installed outside the battery swap station or energy storage station. Since the assembly hole is not directly opened on the surface of the panel, but is provided in the column inside the panel, the strength of the panel will not be reduced, and deformation of the panel due to excessive local force during use will be avoided, thereby improving the structural strength of the panel itself and the structural strength of the panel connection, and improving the overall strength of the battery swap station or energy storage station. And because the assembly hole is a blind hole, even if rainwater penetrates into the interior of the assembly hole from the gap between the assembly hole and the assembly part, it will not further enter the interior of the battery swap station or energy storage station, thereby improving the waterproof sealing performance of the battery swap station or energy storage station.

[0008] Preferably, the column extends to the second layer board and abuts against or adheres to the second layer board.

[0009] In this solution, the column connects the first layer of panels and the second layer of panels into a whole, thereby improving the strength of the warehouse panel.

[0012] Preferably, the first layer and the second layer are made of carbon fiber, polymer composite material or SMC resin material;

[0013] And / or, the column is made of resin material.

[0014] In this solution, the above-mentioned materials are used for the first layer plate, the second layer plate and the column, which can achieve lightweight storage panels while meeting the structural strength requirements of the battery swap station or energy storage station, and is more convenient to install.

[0015] Preferably, the storage panel also has an insulation layer, which is sandwiched between the first layer of panels and the second layer of panels, and the insulation layer includes inorganic foaming material, rock wool, polyurethane foam or aerogel felt.

[0016] In this solution, the panel adopts a three-layer composite structure to enhance the strength of the panel. The insulation layer is used to insulate and keep the temperature inside the power swap station or energy storage station from being too high or too low, thus reducing the impact of the temperature on the internal equipment of the power swap station or energy storage station.

[0017] Preferably, the storage plate further comprises a first connecting column and / or a second connecting column;

[0018] The first connecting column is arranged on the first layer board, the second connecting column is arranged on the second layer board, and the first layer board and the second layer board are abutted and fixed by the first connecting column and / or the second connecting column.

Therefore, the above-mentioned arrangement facilitates the first connecting column and / or the second connecting column to pass through the insulation layer to realize the connection between the first layer of boards and the second layer of boards, so as to improve the connection strength between the first layer of boards and the second layer of boards.

[0024] Preferably, the opposite ends of the storage plate are provided with a raised end and a mating end, and the raised end and the mating end both protrude from the same side surface of the storage plate and extend in the same direction, so that the raised end and the mating end on two adjacent storage plates can overlap each other when multiple storage plates are assembled.

[0025] In this solution, multiple warehouse panels are connected by overlapping the protruding ends and the matching ends. The warehouse panels are easy to assemble, and the production cost is low after the warehouse panels are modularized. In addition, the strength of the connecting parts after assembly by overlapping is higher, and the connection is more stable. At the same time, the connecting gaps can also be covered to make the water tightness better.

The arrangement of the above-mentioned multiple bending portions on the edge of the storage panel improves the structural strength of the storage panel and the connection strength of the connection. The third bending portion and the fourth bending portion facilitate the flow of rainwater on the second transition portion, avoid water accumulation on the surface of the storage panel, and improve the waterproof performance.

[0038] Preferably, at the mating end, the edge of the second layer of board is bent toward the first layer of board, and the edge of the second layer of board is clamped between the edge of the first layer of board and the side surface of the raised portion of the adjacent library board close to the mating end, and the outer surface of the edge of the second layer of board is in contact with the outer surface of the edge of the first layer of board at the raised end of the adjacent library board.

[0039] In the present solution, the first layer and the second layer of the panel at the mating end of the panel are bent to form a structure in which the upper and lower layers are joined, so that a sealing structure is formed at the edge of the mating end, and the edge of the second layer of the panel at the mating end fits with the edge of the second layer of the panel at the raised end and the edge of the first layer of the panel to minimize the gap between the three, and the panel is completely sealed at the side connection to prevent rainwater and other liquids from seeping into the battery swap station or energy storage station from the connection.

[0118] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0119] Figure 2-4 An embodiment of the present invention illustrates a battery swap station.

[0120] like Figure 2 As shown, the battery swap station includes a battery swap platform 110 and two charging rooms 120 respectively arranged on both sides of the battery swap platform 110, and a battery swap vehicle (not shown) that travels between the battery swap platform 110 and the charging room 120 for disassembling and installing the battery pack of the vehicle. The battery swap station may also include a monitoring room, a storage room, etc.

[0121] The battery swap platform 110 is used to carry vehicles whose battery packs need to be replaced. The vehicles drive into and dock at the battery swap platform 110, and the battery swap cart removes the old battery packs to be charged on the vehicle and installs fully charged new battery packs. After removing the old batteries from the vehicle, the battery swap cart transports them to the charging room 120 for charging.

[0122] like Figure 3As shown, the charging room 120 is used to place equipment such as a charging rack 121, a lift 122, and a main control box 123. The charging rack 121 is used to accommodate battery packs and charge old battery packs. The lift 122 is used to exchange battery packs with the battery swapping vehicle, and to take the battery packs out of the charging rack 121 or put them into the charging rack 121. At least two rows of charging racks 121 are arranged side by side in the charging room 120 perpendicular to the direction of vehicle travel. The lift 122 is arranged in the lifting area 124 between the two rows of charging racks 121. The main control box 123 is arranged on one side of the charging room 120 close to the battery swapping platform 110. The main control box 123 is used to control the electrical equipment in the battery swapping station.

[0123] like Figure 4 As shown, the battery swap station of this embodiment is supported by a plurality of frames 130 and is divided into a plurality of functional rooms such as a charging room 120, a monitoring room (not shown in the figure), etc. The outer surface of the frame 130 is covered with a storage panel combination unit to isolate the inside and outside of the functional room and prevent external impurities such as rainwater and dust from entering the interior of the battery swap station and causing damage to the electrical components in the battery swap station such as the charging rack 121 and the main control box 123.

[0124] The battery swap station has a top surface, a side surface and a bottom surface, and the top surface and the side surface of the battery swap station are covered with a storage panel assembly unit, and the storage panel assembly unit is connected to the frame 130 of the battery swap station by means of snap-fitting, etc. This embodiment provides a storage panel assembly unit covering the top surface of the battery swap station, and the storage panel assembly unit is assembled from a plurality of separate storage panels 140.

[0125] like Figure 1 and Figure 5-8 As shown, the storage plate 140 includes a first plate 410 and a second plate 420. The first plate 410 is provided with a plurality of protruding units 200 protruding in a direction away from the second plate 420 and extending in the same direction. Figure 5 As shown, a plurality of protrusion units 200 are arranged along the second direction ( Figure 5 The storage plate 140 further includes a main body 320 located between the protrusion 210 and the matching portion 220, and a strip groove 310 is formed between two adjacent protrusion units 200. The strip groove 310 is formed above the main body 320, and the two ends of the strip groove 310 in the second direction are connected. Among them, "extending along the second direction" in this embodiment means that the extension direction is roughly parallel to the second direction, including but not limited to being parallel, and the angle between the extension direction and the second direction within 45° can be considered as extending along the second direction.

[0126] When rainwater or other liquids from the outside fall to the top of the battery swap station, they can first flow into the strip groove 310 under the guidance of the raised unit 200, and then flow out of the storage plate 140 through the two ends of the strip groove 310, so as to ensure that the water flow on the storage plate 140 can be discharged in time, thereby enhancing the waterproof effect of the storage plate 140, thereby enhancing the waterproof effect of the battery swap station, and at the same time, improving the structural strength of the storage plate 140 itself and the structural strength of the connection of the storage plate 140.

[0127] like Figure 6 As shown, the first layer plate 410 is provided with a plurality of first columns 530 extending toward the second layer plate 420, and a first assembly hole 531 is provided in the first column 530. A through hole is provided on the first layer plate 410 of the main body 320, and the first assembly hole 531 is connected to the outside of the first layer plate 410 of the main body 320 (the side located outside the battery swap station) through the through hole on the first layer plate 410 of the main body 320. The first assembly hole 531 is a blind hole, and the first assembly hole 531 is used to install an assembly part to connect other equipment installed outside the battery swap station, such as solar power generation equipment. By setting the first column 530 between the first layer plate 410 and the second layer plate 420, it is possible to achieve the connection of other equipment installed outside the battery swap station while improving the strength of the warehouse plate. Since the first assembly hole 531 is not directly opened on the surface of the storage plate 140, but is set in the first column 530 inside the storage plate 140, the strength of the storage plate 140 will not be reduced, and the deformation of the storage plate 140 due to excessive local force during use will be avoided, thereby improving the structural strength of the storage plate 140 itself and the structural strength of the connection of the storage plate 140, and improving the overall strength of the battery swap station. And because the first assembly hole 531 is a blind hole, even if rainwater penetrates into the interior of the assembly hole from the gap between the assembly hole and the assembly part, it will not further enter the interior of the battery swap station or energy storage station, thereby improving the waterproof sealing performance of the battery swap station or energy storage station.

[0128] In this embodiment, the first column 530 is installed on the first layer plate 410 corresponding to the main body 320, that is, the first column 530 is arranged on the first layer plate 410 of the storage plate 140 at intervals from the protrusion unit 200. In other alternative embodiments, the first column 530 can also be installed on the first layer plate 410 of the protrusion unit 200, and is arranged inside the protrusion unit 200.

[0129] The wall surface of the first assembly hole 531 is flush with the wall surface of the through hole on the corresponding first layer plate 410, which facilitates the rapid positioning of the assembly parts during installation, and the first column 530 is not displayed on the outside of the battery swap station, making the structure more flat.

[0130] The aperture of the first assembly hole 531 is the same as the aperture of the corresponding through hole on the first layer board 410, so that the inner wall of the first assembly hole 531 and the inner wall of the through hole on the corresponding first layer board 410 can fit tightly with the outer wall of the corresponding assembly part, reducing the size of the gap and further improving the waterproof performance.

[0131] In this embodiment, the first assembly hole 531 and the through hole on the first layer plate 410 are both threaded holes, which can be installed with assembly parts such as bolts. In other alternative embodiments, the first assembly hole 531 and the through hole on the first layer plate 410 can be replaced with other structures that can realize the connection between the storage plate 140 and the external equipment of the battery swap station.

[0132] One end of the first column 530 is fixed on the first layer plate 410, and the other end of the first column 530 extends toward the second layer plate 420 and extends to the second layer plate 420 to be connected to the second layer plate 420. The first column 530 connects the first layer plate 410 and the second layer plate 420 into a whole, thereby improving the strength of the storage plate 140.

[0133] The connection and fixing method between the first column 530 and the first layer 410 and the second layer 420 can be one or more of the methods of gluing, clamping, beads or bolting. The above fixing methods are simple in process, more convenient in assembly and manufacturing, and have good fixing effects. In addition, the first column 530 can also be integrally formed with the first layer 410. When preparing the first layer 410, the mold hole for the first column 530 is directly reserved in the mold, and one-time molding is achieved by casting. The one-piece connection and fixing method has a simple process and high connection strength. It can omit the assembly steps of the first column 530 and the first layer 410, and shorten the production time of the storage plate 140.

[0134] This embodiment does not have any clear restrictions on the materials of the first layer 410 and the second layer 420. It is preferred to use carbon fiber, polymer composite material or SMC resin material, which can meet the structural strength requirements of the battery swap station while achieving lightweight storage panel 140, and is more convenient to install. The SMC composite material is a sheet-shaped molded material formed by unsaturated polyester resin, reinforcing material and auxiliary material, which is formed by cutting and molding. The first layer 410 and the second layer 420 are preferably made of the same material to facilitate production and procurement. In other alternative embodiments, the first layer 410 and the second layer 420 can also be made of different materials, but at least the strength of the first layer 410 and the second layer 420 must meet the requirements.

[0135] Since the first column 530 and the first layer plate 410 in this embodiment are integrally formed, the material of the first column 530 is the same as that of the first layer plate 410. In other alternative embodiments, when the first column 530 is connected and fixed to the first layer plate 410 by other means, the first column 530 and the first layer plate 410 can be made of different materials. The first column 530 can be made of resin material, wherein the resin can be unsaturated polyaldehyde resin, and the resin material is light in weight, high in strength, and low in cost, thereby reducing the production cost of the storage plate 140.

[0136] like Figure 7 As shown, the second layer plate 420 is provided with a plurality of second columns 540 extending toward the first layer plate 410, the second columns 540 are provided with second assembly holes 541, the second layer plate 420 is provided with through holes, the second assembly holes 541 are connected to the outside of the second layer plate 420 (the side located inside the battery swap station) through the through holes on the second layer plate 420, and the second assembly holes 541 are used to connect with the frame 130 or other internal equipment of the battery swap station to fix the storage plate 140 to the battery swap station. Since the second assembly holes 541 are not directly provided on the surface of the storage plate 140, but are provided in the columns inside the storage plate 140, the strength of the storage plate 140 will not be reduced, and deformation of the storage plate 140 due to excessive local force during use will be avoided, thereby improving the overall strength of the battery swap station.

[0137] In this embodiment, the second column 540 is installed on the second layer plate 420 corresponding to the body 320, that is, the second column 540 is spaced apart from the protrusion unit 200. In other alternative embodiments, the second column 530 can also be installed on the second layer plate 420 corresponding to the protrusion unit 200, and is arranged inside the protrusion unit 200.

[0138] The second assembly hole 541 is a blind hole. Even if rainwater or other liquids can enter the interior of the storage plate 140, they cannot penetrate into the interior of the battery swap station through the gap between the second assembly hole 541 and the assembly part, thereby improving the waterproof performance of the battery swap station.

[0139] The wall surface of the second assembly hole 541 is flush with the wall surface of the through hole on the corresponding second layer plate 420, which facilitates the rapid positioning of the assembly parts during installation, and the second column 540 is not displayed inside the battery swap station, making the structure more flat.

[0140] The aperture of the second assembly hole 541 is the same as the aperture of the corresponding through hole on the second layer board 420, so that the inner wall of the second assembly hole 541 and the inner wall of the through hole on the corresponding second layer board 420 can fit tightly with the outer wall of the corresponding assembly part, reducing the size of the gap and further improving the waterproof performance.

[0141] The material of the second column 540 and the connection and fixing method between the second column 540 and the first layer board 410 and the second layer board 420 can refer to the material of the first column 530 and the connection and fixing method between the first column 530 and the first layer board 410 and the second layer board 420 mentioned above.

[0142] In this embodiment, the second assembly hole 541 and the through hole on the second layer board 420 are both threaded holes, and the assembly part that matches the second assembly hole 541 is a buckle 600. Figure 8 As shown, the buckle 600 includes a connecting portion 610 and a clamping portion 620. The clamping portion 620 is provided with a through hole for the connecting portion 610 to pass through. The connecting portion 610 of the buckle 600 in this embodiment is a bolt, and the connecting portion 610 passes through the through hole on the clamping portion 620 to achieve fixation with the second connecting plate 440. Figure 6 As shown, the connecting portion 610 passes through and screws into the through hole on the snap-fit ​​portion 620, the through hole on the second connecting plate 440, and the second assembly hole 541 in the second column 540 from bottom to top, thereby fixing the snap 600 on the storage plate 140. The snap-fit ​​portion 620 of the snap 600 is located on the outer side of the second layer plate 420 (the side facing the inside of the battery swap station), and is used to connect with the frame 130 or other internal equipment of the battery swap station.

[0143] In other alternative embodiments, the second assembly hole 541 and the through hole on the second layer plate 420 may be replaced by other structures that can connect the storage plate 140 to the frame 130 or other internal equipment of the battery swap station.

[0144] This embodiment provides a buckle form, but the present invention is not limited thereto, and other existing buckle forms may also be used.

[0145] In other alternative embodiments, the second column 540 may not be provided between the first layer 410 and the second layer 420. Alternatively, only one end of the column is connected to the first layer 410 or the second layer 420, and the other end of the column is not abutted. In this case, the column only serves to install the assembly.

[0146] The assembly holes in this embodiment are only provided on the column located in the main body 320. In other alternative implementations, the column with the assembly holes may also be provided in the protrusion unit 200. The main reason for providing the assembly holes on the column is that the structure of the main body 320 is flatter and the equipment installed thereon is more stable.

[0147] like Figure 6As shown, the panel 140 also has an insulation layer 700, which is sandwiched between the first layer 410 and the second layer 420. The insulation layer 700 is used to provide heat insulation and ensure that the temperature inside the battery swap station is not too high or too low, thereby reducing the impact of the temperature on the internal equipment of the battery swap station. The first layer 410 of the panel 140, the insulation layer 700, and the second layer 420 of the panel 140 form a three-layer composite structure, further enhancing the strength of the panel 140.

[0148] The thermal insulation layer 700 is preferably made of a material with good thermal insulation properties, such as inorganic foam material, rock wool, polyurethane foam or aerogel felt, etc., which not only has good thermal insulation effect but also is light in weight.

[0149] The thermal insulation layer 700 has a through hole corresponding to the position of the column (the first column 530 and the second column 540) located in the main body 320, and the column is connected and fixed through the through hole. Since the first layer 410, the second layer 420 and the thermal insulation layer 700 of the storage plate 140 form a three-layer composite structure, the first layer 410 and the second layer 420 are located on both sides of the thermal insulation layer 700, and the thermal insulation layer 700 is sandwiched in the middle, the through hole is opened on the thermal insulation layer 700 to facilitate the column to penetrate the thermal insulation layer 700 to achieve the connection between the first layer 410 and the second layer 420, thereby improving the connection strength between the first layer 410 and the second layer 420, and can keep the position of the thermal insulation layer 700 relative to the first layer 410 and the second layer 420 fixed. In other alternative embodiments, in order to further ensure the position of the insulation layer 700 relative to the first layer 410 and the second layer 420, the first layer 410 and the second layer 420 can be respectively fixed on both sides of the insulation layer 700 by threads, or the first layer 410, the second layer 420 and the insulation layer 700 can be connected by bonding or the like.

[0150] The storage plate 140 further includes a plurality of connecting columns, which are disposed in the protruding unit 200 of the storage plate 140, one end of which is connected to the inner surface of the first layer plate 410, and the other end of which is abutted against the corresponding second layer plate 420. The connecting columns are used to connect the first layer plate 410 and the second layer plate 420, and to enhance the strength of the storage plate 140.

[0151] Specifically, the storage plate 140 includes a plurality of first connecting columns 510 and a plurality of second connecting columns 520, the first connecting columns 510 and the second connecting columns 520 correspond to each other one by one, and the first connecting columns 510 and the second connecting columns 520 are both arranged in the protruding unit 200. The first connecting columns 510 are arranged on the first layer plate 410, and the second connecting columns 520 are arranged on the second layer plate 420. The first layer plate 410 and the second layer plate 420 are abutted and fixed by the first connecting columns 510 and the second connecting columns 520. The first connecting columns 510 and the second connecting columns 520 connect the first layer plate 410 and the second layer plate 420 as a whole, thereby improving the strength of the storage plate 140.

[0152] Specifically, the first connecting column 510 and the second connecting column 520 are arranged between the first layer board 410 and the second layer board 420, one end of the first connecting column 510 is fixed on the side of the first layer board 410 facing the second layer board 420, and the other end of the first connecting column 510 extends in the direction of the second layer board 420, one end of the second connecting column 520 is fixed on the side of the second layer board 420 facing the first layer board 410, and the other end of the second connecting column 520 extends in the direction of the first layer board 410, and the end of the first connecting column 510 away from the first layer board 410 is abutted and fixed with the corresponding end of the second connecting column 520 away from the second layer board 420.

[0153] In other alternative embodiments, the first layer board 410 and the second layer board 420 may also be connected and fixed in abutment by only a single connecting column, that is, the first connecting column 510 mentioned above may directly extend to the second layer board 420 and be fixed in abutment with the second layer board 420. In this connection mode, it is not necessary to set up the second connecting column 520. Alternatively, the second connecting column 520 mentioned above may directly extend to the first layer board 410 and be fixed in abutment with the first layer board 410. In this connection mode, it is not necessary to set up the second connecting column 520.

[0154] Of course, in actual production and use, the storage plate 140 can simultaneously include one or more of the three connection methods between the first layer plate 410 and the second layer plate 420 (the first connecting column 510 and the second connecting column 520 abut against each other, the first connecting column 510 directly abuts against the second layer plate 420, and the second connecting column 520 directly abuts against the first layer plate 410).

[0155] The connection and fixation between the first connection column 510 and the first layer board 410, the connection and fixation between the second connection column 520 and the second layer board 420, the connection and fixation between the first connection column 510 and the second connection column 520, the connection and fixation between the first connection column 510 and the second layer board 420, and the connection and fixation between the second connection column 520 and the first layer board 410 can be selected by one or more of the following methods: gluing, snap-fitting, beading or bolting, that is, the above five connection and fixation can use the same fixing method or different fixing methods. The above fixing method has simple process, more convenient assembly and manufacturing, and good fixing effect.

[0156] The first connecting column 510 and the first layer 410 and / or the second connecting column 520 and the second layer 420 can also be integrally formed. When preparing the first layer 410 or the second layer 420, the mold hole of the first connecting column 510 or the second connecting column 520 is directly reserved in the mold, and one-time molding is achieved by pouring. The integrally formed connection and fixing method has a simple process and high connection strength, and can omit the assembly steps of the first connecting column 510 and the first layer 410 and / or the assembly steps of the second connecting column 520 and the second layer 420, thereby shortening the production time of the storage board 140.

[0157] This embodiment only involves three types of connection and fixation, namely, the connection and fixation between the first connection column 510 and the first layer plate 410, the connection and fixation between the second connection column 520 and the second layer plate 420, and the connection and fixation between the first connection column 510 and the second connection column 520. In this embodiment, the first connection column 510 and the first layer plate 410 are integrally formed, the second connection column 520 and the second layer plate 420 are integrally formed, and the first connection column 510 and the second connection column 520 are glued and fixed. The connection and fixation method in this embodiment does not need to be secondary processed on the first connection column 510 and / or the second connection column 520 and / or the first layer plate 410 and / or the second layer plate 420, such as opening a connection hole for bolts to pass through, or processing and forming a clamping part on it, etc., thereby shortening the production time of the warehouse plate 140 and improving efficiency.

[0158] The requirements on the materials of the first connecting pillar 510 and the second connecting pillar 520 may refer to the requirements on the first pillar 530 mentioned above.

[0159] In other alternative embodiments, the first connecting column 510 and the second connecting column 520 can be made of the same material or different materials, and technicians can flexibly adjust according to actual needs, but at least the strength of the first connecting column 510 and the second connecting column 520 meets the requirements when needed.

[0160] The thermal insulation layer 700 has through holes corresponding to the positions of the first connecting column 510 and the second connecting column 520, and the first connecting column 510 and the second connecting column 520 are connected and fixed through the through holes. Since the first layer 410, the second layer 420 and the thermal insulation layer 700 of the storage plate 140 form a three-layer composite structure, the first layer 410 and the second layer 420 are located on both sides of the thermal insulation layer 700, and the thermal insulation layer 700 is sandwiched in the middle, the through holes are opened on the thermal insulation layer 700 to facilitate the first connecting column 510 and the second connecting column 520 to penetrate the thermal insulation layer 700 to achieve the connection between the first layer 410 and the second layer 420, thereby improving the connection strength between the first layer 410 and the second layer 420, and enabling the thermal insulation layer 700 to remain fixed relative to the first layer 410 and the second layer 420. In other alternative embodiments, in order to further ensure the position of the insulation layer 700 relative to the first layer 410 and the second layer 420, the first layer 410 and the second layer 420 can be respectively fixed on both sides of the insulation layer 700 by threads, or the first layer 410, the second layer 420 and the insulation layer 700 can be connected by bonding or the like.

[0161] like Figure 6 As shown, the storage plate 140 includes a protruding end 141 and a mating end 142 that are arranged opposite to each other, and the protruding end 141 and the mating end 142 are respectively arranged to extend along the first direction ( Figure 5 The protruding end 141 and the mating end 142 are opposite to each other in the X direction in the direction of the storage plate 140, and a protruding cavity is formed in each of the protruding end 141 and the mating end 142. Both the protruding end 141 and the mating end 142 protrude from the same side surface of the storage plate 140 and extend in the same direction. The mating end 142 is used to match with the protruding end 141 of the adjacent storage plate 140 when multiple storage plates 140 are assembled. In this embodiment, multiple storage plates 140 are connected by overlapping the protruding end 141 and the mating end 142. The storage plates 140 are easy to assemble, and the production cost is low after the modularization of the storage plates. In addition, the strength of the connecting part after the overlapping assembly is higher, and the connection is more stable. At the same time, the connecting gap can also be covered to make it more watertight. Among them, "extending in the same direction" in this embodiment means that the extending directions are roughly parallel, including but not limited to parallel, and the extending directions are considered to be extending in the same direction at an angle of less than 45°.

[0162] like Figure 5 and Figure 6As shown, the plurality of protruding units 200 include a protruding portion 210 disposed at a protruding end 141 of the storage panel 140, and a matching portion 220 disposed at a matching end 142 of the storage panel 140. At the protruding end 141, the edge of the storage panel 140 protrudes upward to form the protruding portion 210; at the matching end 142, the edge of the storage panel 140 protrudes upward to form the matching portion 220, and the matching portion 220 is used to cover the outer side of the protruding portion 210 of the adjacent storage panel 140 when the plurality of storage panels 140 are assembled. When two adjacent storage panels 140 are connected, the matching portion 220 of one storage panel 140 will cover and be sleeved on the outer side of the protruding portion 210 of another adjacent storage panel 140 to form a superimposed structure, so that the connection strength of the two adjacent storage panels 140 is higher, and the connection gap between the two storage panels 140 can also be covered to prevent liquids such as rainwater from penetrating from the gap, thereby improving the waterproof performance of the storage panel 140.

[0163] like Figure 6 As shown, when two storage panels 140 are assembled, the inner surface of the matching portion 220 of one storage panel 140 is fitted to the outer surface of the raised portion 210 of another adjacent storage panel 140, so that the matching portion 220 can cover the outer side of the raised portion 210 of the adjacent storage panel 140 when multiple storage panels 140 are assembled, and prevent the rainwater level of the storage panel 140 from rising when it rains, thereby preventing the accumulated water from seeping into the interior of the storage panel 140 through the gap.

[0164] like Figure 6 As shown, at the raised end 141, the first layer plate 410 is raised in a direction away from the second layer plate 420 to form a raised portion 210, and the side of the first layer plate 410 facing the second layer plate 420 forms a cavity 240 (corresponding to the raised cavity of the raised end 141 mentioned above) due to the raised portion 210. At the mating end 142, the first layer plate 410 is raised in a direction away from the second layer plate 420 to form a mating portion 220, and the mating portion 220 is used to cover the outer side of the raised portion 210 of the adjacent library plate 140. Both the raised portion 210 and the matching portion 220 are formed by the raised portion of the first layer 410. When the two storage panels 140 are connected, the matching portion 220 of the storage panel 140 will cover and be sleeved on the outer side of the raised portion 210 of another adjacent storage panel 140 to form a stacked structure, which can make the connection stronger and can also cover the connecting gap between the two storage panels 140 to prevent rainwater and other liquids from seeping into the gap, thereby improving the waterproof performance of the storage panel 140.

[0165] like Figure 6As shown, at the protruding end 141, the edge of the second layer plate 420 is bent toward the first layer plate 410 of the protruding end 141, and the edge of the first layer plate 410 of the protruding end 141 is bent toward the second layer plate 420 of the protruding end 141, and the first layer plate 410 of the protruding end 141 covers the outer surface of the second layer plate 420 of the protruding end 141, and the inner surface of the edge of the first layer plate 410 is attached to the outer surface of the edge of the second layer plate 420. By bending the first layer plate 410 and the second layer plate 420 of the protruding end 141 of the storage plate 140 toward each other to form a structure in which the upper layer covers the lower layer, the edge of the protruding end 141 forms a sealing structure to prevent liquids such as rainwater from penetrating into the interior of the storage plate 140.

[0166] like Figure 6 As shown, the first layer plate 410 of the raised end 141 is bent to form a trapezoidal structure. At the raised end 141, the edge portion of the first layer plate 410 includes a first bent portion 211 bent in a direction away from the second layer plate 420 (towards the outside of the battery swap station) and a second bent portion 212 bent in a direction toward the second layer plate 420 (towards the inside of the battery swap station). A first transition portion 213 is provided between the first bent portion 211 and the second bent portion 212. The first transition portion 213 extends in a horizontal direction and is used to connect the first bent portion 211 and the second bent portion 212, thereby connecting the raised end 141 as a whole. The first bending portion 211 and the second bending portion 212 constitute two oblique sides of the trapezoid, and the first transition portion 213 forms the top side of the trapezoid. The arrangement of multiple bending portions forms a structure that matches the shape of the mating end 142, which facilitates the connection and assembly between adjacent storage panels 140. The arrangement of multiple bending portions at the edge of the storage panel 140 improves the structural strength of the storage panel 140 and the connection strength of the joints, thereby improving the waterproof performance.

[0167] like Figure 6As shown, the outer surface of the first transition portion 213 is provided with a groove 214, and the two ends of the groove 214 along the second direction penetrate the first layer plate 410 of the protruding end 141, and the groove 214 is used to install the sealing member 215, and one side of the sealing member 215 is clamped inside the groove 214, and the other side can be pressed against the inner side of the top of the matching end 142 of another adjacent storage plate 140. When the two storage plates 140 are assembled, the sealing member 215 is sandwiched between the outer surface of the protruding end 141 of one storage plate 140 and the inner surface of the matching end 142 of the adjacent storage plate 140. When the accumulated water rises from the gap between the raised end 141 and the mating end 142 of the two storage panels 140, it can be blocked by the sealing member 215 disposed on the top and cannot enter the interior of the power exchange station from the gap between the raised end 141 and the mating end 142, further strengthening the sealing performance of the connection between the two adjacent storage panels 140, preventing rainwater and other liquids from entering the interior of the storage panels 140 from the gap at the connection between the raised end 141 and the mating end 142, and improving the waterproof effect of the storage panels 140. In other alternative embodiments, the groove 214 can also be disposed on the first bending portion 211 or the second bending portion 212, and the position of the sealing member 215 also changes accordingly with the position of the groove 214.

[0168] In this embodiment, the sealing component 215 is a rubber waterproof strip. In other alternative implementations, the sealing component 215 can also be made of other waterproof materials.

[0169] like Figure 6 As shown, at the mating end 142, the inner surface of the edge of the first layer of panel 410 fits against the outer surface of the raised portion 210 of the adjacent panel 140 away from the mating end 142 to prevent the rainwater level of the panel 140 from rising when it rains, thereby preventing accumulated water from seeping into the interior of the panel 140 through the gap.

[0170] At the mating end 142, the edge of the first layer plate 410 is bent toward the second layer plate 420, and the first layer plate 410 forms a raised cavity 224 (corresponding to the raised cavity of the mating end 142 mentioned above), and the cavity 224 is used to accommodate the raised portion 210 of the adjacent panel 140 when the two panels 140 are assembled, and the inner surface of the first layer plate 410 at the mating end 142 can cover the outer surface of the first layer plate 410 at the raised end 141 of the adjacent panel 140. The connection of the two adjacent panels 140 is achieved by mating the cavity 224 of the mating end 142 of one panel 140 with the raised end 141 of another adjacent panel 140. The connection method is simple and easy to operate, which can improve the assembly efficiency of the panels 140 and prevent the rainwater level from rising when the panels 140 are in the rainy state and seeping into the interior of the panels 140 from the gap between the two panels 140.

[0171] like Figure 6As shown, the first layer plate 410 of the mating end 142 is also bent to form a trapezoidal structure, and the edge portion of the first layer plate 410 of the mating end 142 includes a third bending portion 221 bent in a direction away from the second layer plate 420 (towards the outside of the battery swap station) and a fourth bending portion 222 bent in a direction toward the second layer plate 420 (towards the inside of the battery swap station), and a second transition portion 223 is provided between the third bending portion 221 and the fourth bending portion 222. The second transition portion 223 extends in a horizontal direction and is used to connect the third bending portion 221 and the fourth bending portion 222, thereby connecting the mating end 142 as a whole. The third bend portion 221 and the fourth bend portion 222 constitute two oblique sides of the trapezoid, and the second transition portion 223 forms the top side of the trapezoid. The arrangement of multiple bend portions, on the one hand, forms a structure that matches the shape of the raised end 141, which facilitates the connection and assembly between adjacent storage panels 140. The arrangement of multiple bend portions at the edge of the storage panel 140 improves the structural strength of the storage panel 140 and the connection strength of the connection. The third bend portion 221 and the fourth bend portion 222 facilitate the flow of rainwater on the second transition portion 223 to avoid water accumulation on the surface of the storage panel 140 and improve the waterproof performance.

[0172] At the mating end 142, the edge of the second layer plate 420 is bent toward the first layer plate 410 of the mating end 142, and the second layer plate 420 of the mating end 142 covers the inner surface of the first layer plate 410 of the mating end 142 to close the end of the mating end 142 away from the main body 320. By bending the first layer plate 410 and the second layer plate 420 of the mating end 142 of the storage plate 140 to form a structure where the upper and lower layers are joined, the edge of the mating end 142 forms a sealing structure, thereby ensuring that the side edge of the storage plate 140 on the side where the protruding end 141 is set is closed to prevent liquids such as rainwater from penetrating. The edge of the second layer plate 420 at the mating end 142 is clamped between the edge of the first layer plate 410 and the side surface of the raised portion 210 of the adjacent panel 140 close to the mating end 142 when the two panels 140 are assembled. The outer surface of the edge of the second layer plate 420 fits against the outer surface of the edge of the first layer plate at the raised end 141 of the adjacent panel 140, minimizing the gap between the three and completely sealing the panel 140 from the side connection to prevent rainwater and other liquids from seeping into the battery swap station from the connection.

[0173] In this embodiment, both the raised end 141 and the mating end 142 are trapezoidal structured protrusions, which can not only wrap and cover the seam of the storage board 140, but the raised structure can also play a role in diversion, so that rainwater and other liquids at the seam can flow down along the hypotenuse of the trapezoid to avoid siltation. At the same time, the top edge of the trapezoid is a plane, which can also be used to install other components, such as the sealing member 215. In other alternative embodiments, the raised end 141 and the mating end 142 can also be set to a triangle, a semicircle, etc. according to different needs and situations, as long as it is ensured to be raised in the vertical direction and wrap the seam of the storage board 140, the corresponding effect can be achieved.

[0174] The connection between the first bending portion 211 and the second bending portion 212 and the first transition portion 213 is an arc-shaped chamfer, and the connection between the third bending portion 221 and the third connecting portion 610 and the second transition portion 223 is also an arc-shaped chamfer, which can increase the strength of the connection and make the protrusion 210 and the matching portion 220 fit better in the overlapping state, further improving the water tightness.

[0175] The first connecting column 510 is arranged on the inner surface of the first layer plate 410 of the protruding portion 210 and extends in the direction of the second layer plate 420. The second connecting column 520 is arranged on the inner surface of the second layer plate 420 of the protruding portion 210. The end of the first connecting column 510 away from the first layer plate 410 abuts and is fixed to the end of the corresponding second connecting column 520 away from the second layer plate 420. Along the second direction, a plurality of first connecting columns 510 and second connecting columns 520 evenly arranged along the second direction are arranged inside the protruding portion. The plurality of first connecting columns 510 and the plurality of second connecting columns 520 are evenly distributed in the protruding portion 210, and play the role of connecting, fixing and strengthening the protruding unit 200.

[0176] In other alternative embodiments, the first connecting column 510 and the second connecting column 520 may also be disposed in other protrusion units 200 .

[0177] The diameter of the first connecting column 510 is the same as the diameter of the corresponding second connecting column 520. On the one hand, the outer contours of the first connecting column 510 and the corresponding second connecting column 520 can be aligned to achieve rapid positioning of the first connecting column 510 relative to the corresponding second connecting column 520, thereby improving the assembly efficiency of the storage plate 140. On the other hand, the internal space of the protrusion 210 can be fully utilized to increase the optional range of the diameter size of the first connecting column 510 and the second connecting column 520, and the diameters of the first connecting column 510 and the second connecting column 520 can be set to a larger value to improve the strength of the protrusion 210.

[0178] Reinforcing ribs 511 are also provided on both sides of the first connecting column 510. The reinforcing ribs 511 are arranged in the cavity 240. One side of the reinforcing rib 511 abuts against the first connecting column 510, and the other side of the reinforcing rib 511 abuts against the inner side surface of the first layer plate 410 to further enhance the strength of the storage plate.

[0179] like Figure 6 As shown, the plurality of protrusion units 200 further include a plurality of intermediate protrusions 230 disposed between the protrusion portion 210 and the matching portion 220. The first layer 410 protrudes in a direction away from the second layer 420 to form an intermediate protrusion. The intermediate protrusion 230 and the protrusion portion 210 face the same direction (second direction / Figure 5 The protrusion 210 and the matching portion 220 are both higher than the middle protrusion 230 to prevent the depth of water accumulation on the outer surface of the storage plate 140 from overflowing the highest point of the connection between the two storage plates 140, so that the accumulated water penetrates from the gap at the connection between the two storage plates 140 into the space between the first layer 410 and the second layer 420.

[0180] Specifically, the first layer 410 of the middle protrusion 230 protrudes in a direction away from the second layer 420, and the second layer 420 is in the shape of a flat plate. The side of the first layer 410 facing the second layer 420 also forms a cavity 240 due to the middle protrusion 230. Since the first layer 410 of the middle protrusion 230 faces the outside of the battery swap station, it is convenient to drain water in time. The second layer 420 of the middle protrusion 230 faces the inside of the battery swap station. The flat plate shape can increase the connection area between the storage plate 140 and other components inside the battery swap station. The storage plate 140 is connected to the column inside the battery swap station through the second layer 420. The second layer 420 is set to a flat plate structure, which is convenient for the connection and fixation of the storage plate 140 with the column inside the battery swap station.

[0181] In this embodiment, the inner surface of the first layer plate 410 of the middle protrusion 230 is also provided with a first connecting column 510, which is arranged in the cavity corresponding to the middle protrusion 230, and the inner surface of the second layer plate 420 of the middle protrusion 230 is also provided with a second connecting column 520, and the first connecting column 510 abuts against the second connecting column 520, and is used to connect the first layer plate 410 and the second layer plate 420 of the middle protrusion 230, thereby improving the strength of the middle protrusion 230. In other alternative embodiments, since the protrusion height of the middle protrusion 230 is small, the first connecting column 510 can be provided only on the inner surface of the first layer plate 410 of the middle protrusion 230, and the other end of the first connecting column 510 abuts against the second layer plate 420 of the middle protrusion 230, so as to realize the connection between the first layer plate 410 and the second layer plate 420 of the middle protrusion 230. Alternatively, the second connecting column 520 may be provided only on the inner surface of the second layer plate 420 of the middle protrusion 230 , and the other end of the second connecting column 520 abuts against the first layer plate 410 of the middle protrusion 230 to achieve the connection between the first layer plate 410 and the second layer plate 420 of the middle protrusion 230 .

[0182] The requirements on the material, size, connection method with the middle protrusion 230 and the like of the first connecting column 510 and the second connecting column 520 arranged at the middle protrusion 230 may refer to the relevant requirements on the first connecting column 510 and the second connecting column 520 arranged at the protrusion part mentioned above.

[0183] The thermal insulation layer 700 has a through hole corresponding to the position of the first connection column 510 and the second connection column 520 disposed at the middle protrusion 230, and the first connection column 510 and the second connection column 520 disposed at the middle protrusion 230 are connected and fixed through the through hole. The convenient column penetrates the thermal insulation layer 700 to achieve the connection between the first layer 410 of the middle protrusion 230 and the second layer 420 of the middle protrusion 230, thereby further improving the connection strength of the first layer 410 and the second layer 420, and can keep the position of the thermal insulation layer 700 relative to the first layer 410 and the second layer 420 fixed.

[0184] In this embodiment, an insulation layer 700 is disposed between the first layer plate 410 and the second layer plate 420 of the protruding unit 200 and between the first layer plate 410 of the main body 320 and the second layer plate 420 of the main body 320, which can enhance the insulation effect of the storage panel 140 on the battery swap station, and can make the insulation effects of various parts of the storage panel 140 roughly the same, thereby reducing the temperature difference of each part. In other alternative embodiments, the insulation layer 700 may not be disposed everywhere between the first layer plate 410 and the second layer plate 420 of the storage panel 140, and the insulation layer 700 may be disposed only between the first layer plate 410 and the second layer plate 420 of the protruding unit 200 or only between the first layer plate 410 of the main body 320 and the second layer plate 420 of the main body 320.

[0185] like Figure 1 As shown, the storage panel 140 further includes a side portion 800, which is located at opposite ends of the storage panel 140 along the extension direction (second direction) of the protruding unit 200, and the side portion 800 is used to close the gap between the first layer plate 410 and the second layer plate 420. The side portion 800 covers the two side edges of the storage panel 140 to close the side edge ends of the storage panel 140, preventing liquids such as rainwater from penetrating into the storage panel 140 from the side edges of the storage panel 140, and then entering the interior of the battery swap station.

[0186] The side portion 800 close to the protrusion 210 is the first side portion 810, and the side portion 800 close to the matching portion 220 is the second side portion 820. The second side portion 820 can cover part of the outer side of the first side portion 810 of the adjacent storage plate 140 when the two storage plates 140 are assembled to achieve the connection between the two adjacent storage plates 140.

[0187] Specifically, the first side portion 810 has a step portion, and the second side portion 820 has an opening groove 821. Part of the outer surface of the first side portion 810 is recessed inward (along the inner side of the second direction) to form a step portion, and the part of the outer surface of the first side portion 810 at the step portion is higher than the part of the outer surface of the first side portion 810 at the recessed portion. The bottom end of the second side portion 820 is recessed upward to form an opening groove 821. The shape of the opening groove 821 matches the step portion, and the opening groove 821 is used to clamp the step portion of the adjacent storage plate 140 when multiple storage plates 140 are assembled. The first side portion 810 of the protrusion 210 of one storage plate 140 and the second side portion 820 of the matching portion 220 of another adjacent storage plate 140 are matched through the step portion and the opening groove 821, so that the two ends of the storage plate 140 form a clamping structure, prevent the relative movement of the connection between the storage plates 140, and improve the water tightness of the connection between the storage plates 140.

[0188] In a preferred embodiment, the first side portion 810 has a bottom plate, and the step portion is formed on the surface of the bottom plate. The height of the step portion relative to the bottom plate is the same as the thickness of the second side portion 820, so that the end face of the step portion and the second side portion 820 are located in the same plane, so that when the two storage plates 140 are assembled, the first side portion 810 and the corresponding second side portion 820 can be flush, which facilitates water flow out from the side and avoids water accumulation on the surface of the connection. In other alternative embodiments, the molding method of the step portion is not limited to the above method, and other structures or molding methods can be used, but it is necessary to ensure that the end face of the step portion and the second side portion 820 are located in the same plane.

[0189] In this embodiment, one end of the side portion 800 close to the first layer plate 410 is flush with the outer surface of the first layer plate 410, and one end of the side portion 800 close to the second layer plate 420 is flush with the outer surface of the second layer plate 420, that is, the upper end of the side portion 800 is flush with the upper end of the corresponding first layer plate 410, and the lower end of the side portion 800 is flush with the lower end of the corresponding second layer plate 420, so that both sides of the storage plate 140 are closed to prevent rainwater and other liquids from entering the interior of the battery swap station from the side of the storage plate 140. In other alternative embodiments, one end of the side portion 800 close to the first layer plate 410 can also be flush with the outer surface of the first layer plate 410, and the other end of the side portion 800 can extend toward the second layer plate 420 and extend out of the lowermost end of the second layer plate 420, that is, extend out of the outer surface of the second layer plate 420, so as to prevent rainwater and other liquids from penetrating into the interior of the storage plate 140 from the connection between the side portion 800 and the second layer plate 420, thereby enhancing the waterproof effect.

[0190] The present embodiment provides a snap-fitting form between a first side portion 810 and a second side portion 820 of an adjacent storage plate 140, but the present invention is not limited thereto. The first side portion 810 and the second side portion 820 of an adjacent storage plate 140 may also be snap-fitted in other forms, for example, the first side portion 810 is merely recessed inwardly in the extension direction of the protrusion 210 to form a shape matching the second side portion 820, or the first side portion 810 and the second side portion 820 of the adjacent storage plate 140 form mutually matching teeth in the first direction.

[0191] The warehouse panel combination unit is formed by connecting multiple warehouse panels 140 to each other, which is convenient to assemble, and the cost of a single warehouse panel 140 can be lowered through modular production. After assembly, the warehouse panel combination unit has higher strength and better waterproof performance. Multiple warehouse panels 140 are assembled in sequence along the first direction, and the raised ends 141 and the matching ends 142 on the two sides of any two adjacent warehouse panels 140 are connected to each other to form a warehouse panel combination unit. The warehouse panels 140 cooperate and overlap with each other through the raised ends 141 and the matching ends 142, so that the combined warehouse panel combination unit has higher strength and better waterproof performance. The assembly position relationship between two adjacent warehouse panels 140 is as follows:

[0192] like Figure 6 As shown, the raised end 141 of one storage plate 140 is accommodated in the cavity 224 of the mating end 142 of the adjacent storage plate 140, the first bent portion 211 of the raised end 141 is adjacent to the fourth bent portion 222 of the mating end 142, the second bent portion 212 of the raised end 141 is adjacent to the third bent portion 221 of the mating end 142, the second layer plate 420 of the mating end 142 is clamped between the second bent portion 212 of the raised end 141 and the third bent portion 221 of the mating end 142, the first transition portion 213 of the raised end 141 is adjacent to the second transition portion 223 of the mating end 142, and the sealing member 215 is arranged on the top of the first transition portion 213 of the raised end 141, and the two ends of the sealing member 215 are respectively abutted against the first transition portion 213 and the second transition portion 223.

[0193] The frame 130 of the battery swap station in this embodiment is detachably connected to the panel assembly unit, making the assembly between the frame 130 and the panel assembly unit more convenient, and facilitating the installation and maintenance of the battery swap station. The panel assembly unit is used to prevent liquids such as rainwater from entering the frame 130 and the interior of the battery swap station, thereby improving the waterproof performance of the battery swap station.

[0194] Specifically, Figure 6 As shown, a slot is provided on the frame 130 at a position corresponding to the buckle 600 of the second connecting plate 440, and the engaging portion 620 of the buckle 600 is inserted into the slot on the frame 130. The storage plate assembly unit is clamped in the slot of the frame 130 by the buckle 600, which is convenient to connect and has high strength. In other alternative embodiments, the frame 130 of the battery swap station can also be detachably connected to the storage plate assembly unit by other connection methods, such as bolt connection.

[0195] Although the present embodiment provides a storage panel combination unit for covering the top surface of a battery swap station, in actual use, the storage panel combination unit in the present embodiment can also be used to cover the side of the battery swap station.

[0196] The battery swap station of the present invention is not limited to Figure 2-4 In the form shown, the structures such as the storage panel combination unit, frame 130, storage panel 140 provided by the present invention are also applicable to battery swap stations adopting other structures or layouts.

[0197] Likewise, the structures of the storage panel combination unit, frame 130, storage panel 140, etc. provided by the present invention are also applicable to energy storage stations with storage and charging functions.
