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 almost exhausted 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 swap stations. Since the batteries of electric vehicles need to be charged frequently, there are high requirements for the number and distribution of battery swap stations. Battery swap stations often need to be set up in an open-air environment and face the influence of natural factors, while the inside of the battery swap station needs to ensure a dry and stable working environment. In the prior art, battery swap stations are often due to rain, accumulated rain and other reasons. The watertightness of the existing battery swap station is poor. Water can easily penetrate from the battery swap station from the battery swap station to the inside of the battery swap station, causing the battery swap station to fail to work normally and bring safety hazards.

[0117] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0118] Figure 2 An embodiment of the present invention illustrates a battery swap station.

[0119] The battery swap station 100 includes a battery swap platform 101, two charging rooms 102 respectively arranged on both sides of the battery swap platform 101, and a battery swap vehicle that travels between the battery swap platform 101 and the charging rooms 102 for disassembling and installing the battery pack of the vehicle. The battery swap station 100 may also include a monitoring room, a storage room, etc.

[0120] The battery swap platform 101 is used to carry vehicles whose battery packs need to be replaced. The vehicles drive into and dock at the battery swap platform 101. 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 102 for charging.

[0121] The charging room 102 is equipped with a charging rack, an elevator, a main control box and other equipment. The charging rack is used to accommodate battery packs and charge old battery packs. The elevator is used to exchange battery packs with the battery swapping vehicle and to take the battery packs out of the charging rack or put them into the charging rack.

[0122] like Figure 3 As shown, the battery swap station 100 of this embodiment 1 is supported by a frame 105 and divided into multiple functional rooms such as a charging room 102, a monitoring room, etc., and its outer surface is covered with a storage plate 112 to isolate the inside and outside of the functional room to prevent external impurities such as rainwater and dust from entering the interior of the battery swap station 100 and causing damage to electrical components in the battery swap station 100 such as a charging rack and a main control box.

[0123] The battery swap station 100 has a top surface, a side surface and a bottom surface. The top surface and the side surface of the battery swap station 100 are covered with a panel assembly unit 111. The panel assembly unit 111 is connected to the frame 105 of the battery swap station 100 by means of snap-fit ​​or the like.

[0125] like Figure 4 As shown, the frame 105 includes a plurality of beams 107 and columns 108 combined with each other.

[0126] The storage board assembly unit 111 can be connected to the crossbeam 107 and the column 108 of the frame 105 through the storage board 112. For example, the storage board 112 is provided with a buckle, and the frame 105 is provided with a slot corresponding to the buckle, and the two are assembled together by the engagement of the buckle and the slot.

[0127] like Figures 2 to 5 As shown, the top surface of the battery swap station is covered with a roof 200, which is composed of a plurality of roof panel and warehouse panel combination units 210. The warehouse panels in the roof panel and warehouse panel combination units 210 constituting the roof 200 are roof panel and warehouse panels 220. Unless otherwise specified, the "warehouse panels" described below refer to "roof panel and warehouse panels".

[0128] like Figures 2 to 5 As shown, the top plate warehouse panel combination unit 210 of the present embodiment includes a plurality of top plate warehouse panels 220 connected to form a connection, and each top plate warehouse panel 220 is provided with a protruding end 240 and a mating end 230 at opposite ends, respectively, and the protruding end 240 and the mating end 230 both protrude outward from the same side surface of the top plate warehouse panel 220 and extend in the same direction, and a protruding hollow cavity 247 is formed in the mating end 230, and the protruding hollow cavity 247 in the mating end 230 is used to accommodate the protruding end 240 of the adjacent top plate warehouse panel 220.

[0129] The raised end 240 and the mating end 230 are used to control rainwater from the two ends of the extension direction of the raised end 240 and the mating end 230 to discharge from the panel assembly unit, so as to prevent rainwater from penetrating into the panel from the connection between the panels in the panel assembly unit. The instantaneous rainfall needs to at least overflow the highest point of the raised end 240 or the mating end 230 before it can flow to the connection between the two, thereby enhancing the waterproof effect. Moreover, even if the rainwater overflows the highest point, the raised end 240 and the mating end 230 can guide the rainwater to flow downward, which is convenient for the timely discharge of rainwater. At the same time, the structural strength of the panel assembly unit is improved through the superimposed and mating structure of the raised end 240 and the mating end 230, so as to meet the strength requirements and waterproof requirements of the battery swap station or energy storage station.

[0130] In the present embodiment, the top plate storage plate 220 is a rectangular structure having a first end 281 and a second end 282 opposite to each other and a third end 283 and a fourth end 284 opposite to each other.

In this embodiment, the top plate storage panel 220 is a multi-layer composite structure, and the top and bottom are composed of the first layer 221 and the second layer 222. At the raised end 240 and the mating end 230 of the top plate storage panel 220, the first layer 221 is bent to form a raised portion 241 and a mating portion 231 of corresponding shapes. At the raised end 240, the first layer 221 is raised in a direction away from the second layer 222 to form a raised portion 241, and at the mating end 230, the first layer 221 is raised in a direction away from the second layer 222 to form a mating portion 231. The raised portion 241 of the first layer 221 of the raised end 240 is wrapped by the mating portion 231 of the first layer 221 of the mating end 230 of the adjacent connected panel to form a superimposed structure, which can not only play a connecting role, connecting the two ends of the adjacent panels to form a panel assembly unit, but also play a waterproof role. Through the superimposed method, the raised end 240 of the top panel 220 and the mating end 230 of the adjacent top panel 220 are staggered and connected, and the joint of the two panels is wrapped in the raised superimposed structure, so that water cannot directly penetrate into the joint from the outside of the panel, thereby improving the water tightness of the panel connection.

[0135] The mating end 230 protrudes outward from the surface of the main body 290 , and includes a third bending portion 232 bent away from the main body 290 and a fourth bending portion 233 bent toward the main body 290 , with a second transition portion 234 between the third bending portion 232 and the fourth bending portion 233 .

[0136] The matching portion 231 of the first layer 221 also has a trapezoidal structure, and its shape matches the raised portion 241. It also has a third bend 232 and a fourth bend 233 as two oblique sides, and a second transition portion 234 as a top side. The third bend 232 first extends upward in a direction away from the main body 290, and the fourth bend 233 extends in a direction close to the main body 290. When matched, the matching portion 231 covers and overlaps the raised portion 241, and the three sides of the trapezoid are in contact with each other, so that the connection effect is better. In this embodiment, both the raised portion 241 and the matching portion 231 are raised with a trapezoidal structure, which can not only wrap and cover the joints of the warehouse board, but the raised structure can also play a role in diversion, so that rainwater at the joints can flow down along the oblique sides of the trapezoid to avoid siltation. At the same time, the top side of the trapezoid is a plane, which can also be used to install other components.

[0137] In other embodiments, the raised portion 241 and the matching portion 231 may be set to a triangle or a semicircle according to different needs and situations. As long as they are raised in the vertical direction and wrap the joint of the storage panel, the corresponding effect can be achieved.

[0138] like Figure 1 , 7 As shown in FIG. 8, the connection between the first bending portion 242, the second bending portion 243 and the first transition portion 244 has an arc chamfer, and the connection between the third bending portion 232, the fourth bending portion 233 and the second transition portion 234 also has an arc chamfer. This structure can increase the strength of the connection, and at the same time make the protrusion 241 and the matching portion 231 more closely fit in the overlapping state, further improving the water tightness.

[0139] like Figure 8As shown, when connected, the outer wall of the first bend 242 of the protrusion 241 fits the inner wall of the fourth bend 233 of the matching portion 231. This can play a waterproof role, preventing the rainwater level of the panel assembly unit from rising when it rains and seeping into the interior of the panel through the gap.

[0140] like Figure 1 As shown, in the stacked structure, a hollow cavity 247 is provided between the first layer board 221 and the second layer board 222 .

[0141] like Figure 1 As shown, at the mating end 230, the third bend 232 of the mating portion 231 of the first layer plate 221 extends along the second bend 243 of the protrusion 241 of the adjacent panel, and the fourth bend 233 extends along the first bend 242 of the protrusion 241 of the adjacent panel to below the first bend 242. The connection opening between the water protrusion 241 and the mating portion 231 can be located at the bottom of one side, and the opening has a height difference with the joint of the two panels, so that water cannot directly enter the joint of the two panels through the opening.

[0142] like Figures 1 to 12 As shown, at the raised end 240, the edge of the first layer 221 is bent and extended from the side of the raised portion 241 of the adjacent library plate close to the mating end 230 to the side of the raised end 240 away from the mating portion 231, and the inner surface of the edge of the first layer 221 fits the outer surface of the side of the raised portion 241 away from the mating portion 231.

[0143] At the mating end 230, the edge of the second layer 222 is bent and extended toward the first layer 221, and the edge of the second layer 222 is clamped between the edge of the first layer 221 and the side surface of the raised portion 241 of the adjacent storage plate close to the mating end 230, and the outer surface of the edge of the second layer 222 fits the outer surface of the edge of the first layer 221 of the raised end 240 of the adjacent storage plate.

[0144] In this embodiment, at the raised end 240, the edge of the second layer plate 222 is bent toward the first layer plate 221, and the edge of the second layer plate 222 extends toward the first layer plate 221 at a right angle to the second layer plate 222, and the edge of the first layer plate 221 is bent toward the second layer plate 222, and the edge of the first layer plate 221 extends toward the second layer plate 222 at a right angle to the first layer plate 221, so that the edge of the first layer plate 221 is sleeved on the outside of the edge of the second layer plate 222 at this position, and the inner surface of the edge of the first layer plate 221 is attached to the outer surface of the edge of the second layer plate 222, forming a staggered structure, and the inner cavity between the first layer plate 221 and the second layer plate 222 is closed from the side. At the mating end 230, the edge of the second layer plate 222 bends and extends toward the first layer plate 221, and the edge of the second layer plate 222 extends toward the first layer plate at a right angle to the second layer plate 222 for a distance, and then extends upward along the direction of the second bent portion 243 of the protrusion 241 of the adjacent panel. The vertically extending portion of the edge of the second layer plate 222 fits the edge of the first layer plate 221 of the protrusion 241 of the adjacent panel, and together with the edge of the second layer plate 222 of the protrusion 241 of the adjacent panel, the edge of the first layer plate 221 of the protrusion 241 of the adjacent panel is sandwiched in the middle. The seam of the two panels is closed, filling the gap between the protrusion 241 and the mating portion 231. At the same time, the portion of the edge of the second layer 222 that extends upward in the direction of the second bend 243 of the raised portion 241 of the adjacent panel is sandwiched between the third bend 232 of the mating portion 231 and the second bend 243 of the raised portion 241 of the adjacent panel, and the outer surface of the edge of the second layer 222 simultaneously fits the outer surface of the edge of the first layer 221 of the raised end 240 of the adjacent panel. The gap between the first layer 221 and the second layer 222 at the mating end, as well as the gap between the third bend 232 of the mating portion 231 and the second bend 243 of the raised portion 241 of the adjacent panel are further filled. The panel is closed at the mating end 230, and the joint between the two panels is also made smaller, preventing water from seeping into the battery swap station or energy storage station from the joint. The structure of the second layer is as follows: Fig.11 As shown, Fig.11 This is an oblique downward viewing angle, showing the internal structure of the second layer board 222.

[0145] like Figure 1 , 7As shown in Figures 8 and 9, the top of the raised portion 241 has a groove 245 along the extension direction of the storage panel, and a sealing strip 246 is installed in the groove 245. One side of the sealing strip 246 is stuck inside the groove 245, and the other side is against the inner side of the top of the matching portion 231. The sealing strip is arranged between the top of the raised portion 241 and the top of the matching portion 231. When rainwater accumulates on the storage panel assembly unit and causes water to rise from the gap between the raised portion 241 and the matching portion 231, it is blocked by the sealing strip 246 arranged on the top and cannot flow over the raised portion 241 and penetrate into the battery swap station or energy storage station from the joint between the raised portion 241 and the matching portion 231, thereby improving the waterproofness of the storage panel assembly unit. The sealing strip 246 can be a rubber waterproof strip, or other waterproof materials can be used.

[0146] In this embodiment, the groove 245 is disposed on the outer surface of the first transition portion 244 of the protrusion 241 , and the sealing structure is the sealing strip.

[0147] In other embodiments, a sealing strip may be provided between 242 and 233 . Preferably, the sealing strip is provided close to the end of 233 and between 243 and 232 .

[0148] like Figure 1 As shown, the storage board also has a column 224, and the column 224 is used to install the assembly part 260. The column 224 mainly performs the assembly function. The column 224 is installed on the second layer board 222 and extends toward the first layer board 221. An assembly hole 261 opening toward the second layer board 222 is provided in the column 224, and a corresponding through hole is also provided at a corresponding position on the second layer board 222 to the assembly hole 261 of the column 224, so that the assembly hole 261 can be connected to the outside of the second layer board 222. The assembly part 260 is installed in the assembly hole 261. In this embodiment, the assembly hole 261 is a threaded hole, and the assembly part 260 is a buckle, which is used to clamp the storage board in a matching slot at a corresponding position on the frame. The assembly hole 261 is not directly opened on the surface of the storage panel, but by setting the assembly hole 261 in the column 224 inside the storage panel, there will be no loss of strength of the storage panel, the strength of the storage panel is higher, and deformation of the storage panel due to excessive local force during use is avoided, thereby improving the overall strength of the battery swap station or energy storage station.

[0149] In other embodiments, the assembly hole 261 may be replaced by other conventional connection structures, and the assembly part 260 may be replaced by other conventional connection structures.

[0150] like Fig.12As shown, the assembly part 260 of this embodiment is a buckle, including a connecting part 610 and a clamping part 620. The clamping part 620 is provided with a through hole for the connecting part 610 to pass through. The connecting part 610 of the buckle 600 in this embodiment is a bolt, and the connecting part 610 passes through the through hole on the clamping part 620 to achieve fixation with the second layer plate 222. The connecting part 610 passes through and screws into the through hole on the clamping part 620, the through hole on the second layer plate 222, and the assembly hole 261 in the column 224 from bottom to top, thereby fixing the buckle on the top plate warehouse plate 220. The clamping part 620 of the buckle is located on the outside of the second layer plate 222 (the side facing the inside of the battery swap station), and is used to connect with the frame 105 or other internal equipment of the battery swap station. In other alternative embodiments, the assembly hole 261 and the through hole on the second layer plate 222 can be replaced by other structures that can achieve the connection of the top plate warehouse plate 220 with the frame 105 or other internal equipment of the battery swap station.

[0151] This embodiment provides a buckle form, but the present invention is not limited thereto, and other existing buckle forms may also be used.

[0152] like Figure 1 , 7 As shown in FIG. 8 , the column 224 of this embodiment extends toward the first layer board 221 and abuts against the first layer board 221 , and is connected and fixed to the first layer board 221 by gluing. The column 224 can also play the role of supporting and connecting the first layer board 221 and the second layer board 222 .

[0153] In other embodiments, the column 224 may only serve the function of installing the assembly part 260, without being abutted and fixed to the first layer plate 221, or being connected to the first layer plate 221 by other means, such as welding, threaded bolt connection, etc., or the column 224 and the first layer plate 221 and the second layer plate 222 may be directly cast together by an integral molding method.

[0154] like Figure 1 As shown, the wall surface of the assembly hole 261 is flush with the wall surface of the through hole, so that the buckle can be inserted more easily during installation, and fits the wall surface of the assembly hole 261 and the through hole at the same time.

[0155] like Figure 1 As shown, the assembly hole 261 inside the column 224 is a blind hole, which has only one opening and does not pass through the column 224. Using a blind hole as the assembly hole 261 can prevent water from penetrating into the battery swap station through the assembly hole 261, further improving the waterproofness of the battery swap station.

[0156] like Figure 1 , 7As shown in Figures 8 and 9, the storage board of this embodiment also includes a plurality of connecting columns, which include a first connecting column 225 and a second connecting column 226. The structures of the first connecting column 225 and the second connecting column 226 are similar to the column 224, but they only bear the supporting function and do not have the assembly hole 261, and are not used for installing the buckle. The first layer 221 and the second layer 222 of the storage board are connected by the first connecting column 225 and the second connecting column 226. The first connecting column 225 and the second connecting column 226 are arranged between the first layer 221 and the second layer 222. The first connecting column 225 is arranged on the first layer 221 and extends to the second layer 222. The second connecting column 226 is arranged on the second layer 222 and extends to the first layer 221.

[0157] Optionally, only the first connecting column 225 may be provided at the same position of the storage board, and the first connecting column 225 may be directly abutted and fixed on the second layer board 222, supported between the first layer board 221 and the second layer board 222. It is integrated with the first layer board 221 and fixed to the inner surface of the second layer board 222 by means of gluing or the like.

[0158] Optionally, only a second connecting column 226 may be provided at the same position of the storage board, and the second connecting column 226 may be directly abutted and fixed on the first layer board 221, supported between the first layer board 221 and the second layer board 222. It is integrated with the second layer board 222 and fixed to the inner surface of the first layer board 221 by means of gluing or the like.

[0159] Optionally, a pair of first connecting columns 225 and second connecting columns 226 may be respectively set on the first layer 221 and the second layer 222 at the same position of the storage plate. The two connecting columns are arranged opposite to each other, respectively extending from the inner surfaces of the first layer 221 and the second layer 222 to the opposite layer, and are fixed to each other.

[0160] A plurality of first connecting posts 225 and second connecting posts 226 are evenly distributed at various positions of the storage board, which play the role of connecting and fixing the storage board and strengthening the strength of the storage board. In this embodiment, the storage board has first connecting posts 225 fixedly abutting against the second layer board 222, second connecting posts 226 fixedly abutting against the first layer board 221, and first connecting posts 225 and second connecting posts 226 fixedly abutting against each other.

[0161] In other embodiments, only one or two of the three types of connection column settings may be included.

[0162] Optionally, the first connecting column 225 and the second connecting column 226 are arranged in the hollow cavity 247 in the raised portion 241, and the hollow cavity 247 is connected and fixed by the first connecting column 225 and the second connecting column 226, which can make the strength of the warehouse plate combination unit higher and also cover the connecting gap between the two warehouse plates to prevent liquid from penetrating from the gap, thereby making the warehouse plate combination unit more watertight.

[0163] Optionally, the first connecting column 225 and the second connecting column 226 may also be disposed at other positions of the main body 290 to respectively connect the first layer board 221 and the second layer board 222 to support the storage board.

[0164] In this embodiment, the hollow cavity 247 and the main body 290 of the storage plate are both provided with a plurality of first connecting columns 225 and second connecting columns 226, which support the storage plate from multiple points and increase the strength of the storage plate.

[0165] In other embodiments, the first connecting pillar 225 and the second connecting pillar 226 may be provided only locally, or other supporting structures may be used.

[0166] like Figure 1 , 7 As shown in Figures 8 and 9, the first connecting column 225 and the second connecting column 226 are connected and fixed by gluing, snap-fitting, beads or bolts. The connection method of the connecting column has a simple process, is more convenient to assemble and manufacture, and has a good fixing effect. In this embodiment, the first connecting column 225 and the second connecting column 226 are connected and fixed to the first layer 221, the second layer 222, or each other by gluing. In other embodiments, they can also be connected and fixed by snap-fitting, beads or bolts or other conventional connection methods, as long as the connection strength meets the requirements.

[0167] like Figure 1 , 7 As shown in FIG. 8 , the first connecting column 225 and the second connecting column 226 of this embodiment are integrally molded and cast with the storage board. When preparing the first layer board 221 or the second layer board 222, the mold hole of the first connecting column 225 or the second connecting column 226 is directly reserved in the mold to achieve one-time molding. This type of storage board has a simple process and higher strength.

[0168] In other embodiments, the connection column may also be installed on the first layer board 221 or the second layer board 222 by welding, gluing, or the like.

[0169] like Figure 1 , 7As shown in Figures 8 and 9, the storage panel further includes an insulation layer 223, which is sandwiched between the first layer 221 and the second layer 222 to form a three-layer composite sandwich structure with the first layer 221 and the second layer 222. The insulation layer 223 is made of a material with good thermal insulation properties. In this embodiment, the insulation layer 223 is made of aerogel material, which has good thermal insulation effect and is light in weight.

[0170] In other embodiments, conventional thermal insulation materials such as rock wool or polyurethane foam may also be used.

[0171] like Figure 1 , 7 As shown in Figures 8 and 9, the insulation layer 223 is provided with through holes corresponding to the positions of the first connecting column 225 and the second connecting column 226, and the first connecting column 225 and the second connecting column 226 of the storage board are connected and fixed to the first layer 221 or the second layer 222 through these through holes, so as to connect and fix the insulation layer 223, the first layer 221 and the second layer 222. The first layer 221, the second layer 222 and the insulation layer 223 form a sandwich structure, and the first layer 221 and the second layer 222 are located on both sides of the insulation layer 223, and the insulation layer 223 is sandwiched in the middle to form a three-layer structure, and the first layer 221 and the second layer 222 are respectively connected through the insulation layer 223 by the connecting column passing through the middle, so that the strength of the storage board itself is better.

[0172] In other embodiments, the insulation layer 223 is also fixed to the first layer 221 and the second layer 222 by other means, such as fixing the first layer 221 and the second layer 222 on both sides of the insulation layer 223 by threads, or by bonding, etc.

[0173] like Figure 5 As shown, the first layer board 221 and the second layer board 222 of this embodiment are made of SMC resin material.

[0174] In other embodiments, carbon fiber, polymer composite materials, etc. can also be selected. The column 224 and the connecting column material can be selected from the same material as the layer plate. The first layer plate 221, the second layer plate 222 and the column 224 are selected from the above materials, which are lighter and more convenient to install while ensuring that the strength meets the requirements.

[0175] like Figures 5 to 11 As shown, the two ends of the storage plate along the first direction X are respectively a protruding end 240 and a mating end 230, and the two ends along the second direction Y perpendicular to the first direction X are respectively provided with side portions 237, the side portion 237 of the protruding end 240 is a first side portion 271, and the side portion 237 of the mating end 230 is a second side portion 272, and the second side portion 272 covers part of the outer side of the first side portion 271 of the adjacent storage plate.

[0176] The raised end 240 and the mating end 230 of the storage board are respectively located at the first end 281 and the second end 282 opposite to each other, and the first end 281 and the second end 282 are arranged along the first direction X. The two ends perpendicular to the first direction are the third end 283 and the fourth end 284, and the third end 283 and the fourth end 284 are provided with a side surface portion 237, which is arranged on the side of the third end 283 and the fourth end 284 of the storage board to close the third end 283 and the fourth end 284 of the storage board. The part of the side surface portion 237 located at the raised end 240 is the first side surface portion 271, and the part of the side surface portion 237 located at the mating end 230 is the second side surface portion 272, and the second side surface portion 272 covers part of the outer side of the first side surface portion 271 of the adjacent storage board. The first side surface portion 271 is spliced ​​and wrapped so that the joints of the two are staggered to prevent liquid from penetrating into the storage board from the joints of the sides of the two storage boards.

[0177] like Fig. 9 As shown, the first side portion 271 has a step portion 274, and the second side portion 272 has an opening groove 273, the shape of the opening groove 273 matches the step portion 274, and the opening groove 273 is used to clamp the step portion 274 of the adjacent storage plate when assembling multiple storage plates.

[0178] The first side surface portion 271 further includes a bottom plate 275 . A step portion 274 is formed on a surface of the bottom plate 275 . The height of the step portion 274 relative to the bottom plate 275 is the same as the thickness of the second side surface portion 272 .

[0179] The end surface of the step portion 274 and the second side surface portion 272 are located on the same plane.

[0180] In this embodiment, the first side surface portion 271 has a bottom plate 275 and a step portion 274. The step portion 274 is formed on the bottom plate 275 and extends upward in a direction perpendicular to the bottom plate 275. The surface of the step portion 274 is higher than the bottom plate 275. The inner surface portion of the second side surface portion 272 corresponding to the bottom plate 275 of the first side surface portion 271 is also recessed downward (see Figure 7), its thickness also becomes thinner, so that it can fit and splice with the concave part of the first side part 271. And the edge position of the second side part 272 is provided with an open groove 273 whose shape matches the shape of the step part 274 of the first side part 271. When connected, the open groove 273 just fits with the step part 274, and the concave parts of the two side surface parts 237 fit and splice each other inside and outside. The height of the step part 274 relative to the bottom plate 275 is just equal to the thickness of the second side part 272 after the concave, so that the end face of the step part 274 of the first side part 271 and the second side part 272 are located in the same plane after the connection. The side part 237 of the protruding end 240 and the mating end 230 cooperate through the step part 274 and the open groove 273, so that the other two ends of the warehouse plate form a clamping structure, prevent the relative movement of the connection between the warehouse plates, and improve the water tightness of the connection between the warehouse plates. Furthermore, the connection between the protruding end 240 and the side surface 237 of the mating end 230 is in the same plane, which facilitates water to flow out from the side and avoids water accumulation on the surface of the connection.

[0181] This embodiment provides a form of engaging the side surfaces of two adjacent storage panels, but the present invention is not limited thereto.

[0182] In other embodiments, the side portions of two adjacent storage plates can also be engaged in other forms, for example, only the side portion at the protruding end is recessed inward in the extension direction of the protruding end to form a shape that matches the side portion at the mating end, or the side portion at the protruding end and the side portion at the mating end form mutually matching teeth in the extension direction of the side portions.

[0183] like Figure 5 , Fig. 9 As shown, one end of the side portion 237 close to the upper surface of the storage board is flush with the upper surface, while the other end thereof extends toward the lower surface of the storage board and exceeds the lower surface of the storage board, thereby preventing rainwater from penetrating into the interior of the storage board from the connection between the side portion 237 and the second layer board 222, thereby enhancing the waterproof effect.

[0184] like Fig.10 , Fig.11As shown, the battery swap station also has a top plate corner 250, which is arranged at the position of the first end 281 of the storage panel at the edge of the top plate 200, and is sleeved on the protrusion 241 of the storage panel at the outermost end of the top plate storage panel 220 combination unit and wraps the protrusion 241. The top plate corner 250 is formed by a plurality of corner bends connected to each other, and the plurality of corner bends are respectively attached to several outer surfaces of the protrusion 241, and are connected to form a receiving cavity 254 for accommodating the protrusion 241. The protrusion 241 is located in the receiving cavity 254 of the top plate corner 250, and its top and two side edges are in contact with the inner wall of the receiving cavity 254. The outward side of the top plate corner 250 extends along the outward side edge of the protrusion 241 and extends to the bottom of the edge of the protrusion 241. By setting the corner wrap on the edge of the panel, the corner wrap protrudes along the top surface of the panel and covers the side of the panel. The raised structure can divert rainwater from the edge of the panel or flow into the rain trough of the panel, making it easier to drain rainwater. At the same time, the corner wrap also covers the side of the panel, which can close the side of the panel to prevent rainwater from penetrating into the panel from the side of the panel and then into the battery swap station or energy storage station, thereby improving the waterproofness of the battery swap station or energy storage station. In this embodiment, the overall shape of the corner wrap is similar to the structure of the matching portion 231 of the panel. Covering the three faces of the raised portion 241.

[0185] In other embodiments, the top plate corner wrap 250 may only cover the top and the outside to prevent liquid from penetrating from the outside edge of the storage plate or from the top.

[0186] like Fig.10 , Fig.11 As shown, the top plate corner 250 has three corner bends, the first corner bend 251 fits the inner oblique edge (first bend 242) of the protrusion 241, the second corner bend 252 fits the top of the protrusion 241 (first transition portion 244), and the third corner bend fits the outer oblique edge (second bend 243) of the protrusion 241. The three corner bends also form a trapezoidal structure, which is consistent with the shape of the protrusion 241. This structure also better covers the side of the warehouse board and fits with the warehouse board, improving waterproofness.

[0187] In other embodiments, the corner wrap may not be limited to being formed by a plurality of bends, and may not be limited to a trapezoidal structure but may adopt other structures, as long as the side of the storage panel can be covered and closed to ensure water tightness.

[0188] like Fig.10 , Fig.11As shown, an angle greater than 90° is formed between the first corner bend 251, the second corner bend 252 and the third corner bend 253 in the present embodiment, the inner surface of the first corner bend 251 can be fitted with the outer surface of the first bend 242 of the raised portion 241, the inner surface of the second corner bend 252 can be fitted with the outer surface of the first transition portion 244 of the raised portion 241, and the inner surface of the third corner bend 253 can be fitted with the outer surface of the second bend 243 of the raised portion, thereby making the gap between the top plate corner 250 and the corresponding raised portion 241 smaller, preventing liquids such as rainwater from seeping into the interior of the top plate storage panel 220 from the gap at the connection between the two.

[0189] Since an angle greater than 90° is formed between the first bending portion 242, the first transition portion 244 and the second bending portion 243 of the protrusion 241 in this embodiment, and the inner surface of the top plate corner 250 is in contact with the outer surface of the protrusion 241, an angle greater than 90° is also formed between the first corner bending portion 251, the second corner bending portion 252 and the third corner bending portion 253 in this embodiment. However, in other alternative embodiments, when an angle less than or equal to 90° is formed between the first bend portion 242, the first transition portion 244 and the second bend portion 243 of the protrusion 241, the angles between the first corner bend portion 251, the second corner bend portion 252 and the third corner bend portion 253 in the top plate corner 250 may also change accordingly, so that the inner surface of the top plate corner 250 is always in contact with the outer surface of the protrusion 241, that is, the inner surface of the first corner bend portion 251 is always in contact with the outer surface of the first bend portion 242 of the protrusion 241, the inner surface of the second corner bend portion 252 is always in contact with the outer surface of the first transition portion 244 of the protrusion 241, and the inner surface of the third corner bend portion 253 is always in contact with the outer surface of the second bend portion 243 of the protrusion. Alternatively, no matter how the angles among the first bend portion 242, the first transition portion 244 and the second bend portion 243 of the raised portion 241 change, the angles among the first corner bend portion 251, the second corner bend portion 252 and the third corner bend portion 253 are always greater than 90°, so as to achieve the effect of diverting rainwater, so that rainwater cannot accumulate on the top of the top plate corner 250 but flows down along the first corner bend portion 251 and the third corner bend portion 253 and is discharged.

[0190] like Fig.10 , Fig.11As shown, the edge of the third corner bend 253 exceeds the edge of the first corner bend 251 to form an edge extension 257, which extends downward from the edge of the third corner bend 253. The edge extension 257 can be attached to the side of the top plate 220 and extend downward along the side of the top plate 220 to below the lowest point of the side of the top plate 220, so that the edge of the lowest point of the top plate corner 250 can be lower than the lowest point of the top plate 220, so that liquids such as rainwater can flow down along the third corner bend 253 and flow down from the edge extension 257 instead of flowing to the bottom surface of the top plate 220, further improving the waterproof performance. In other alternative embodiments, the edge extension 257 can also continue to extend from the side of the top plate 220 along the bottom surface of the top plate 220 to completely wrap the outermost end of the top plate 220 to achieve a better waterproof effect.

[0191] The connection between the first corner bend 251 and the second corner bend 252 and the connection between the second corner bend 252 and the third corner bend 253 are both provided with arc chamfers to make the connection smoother, and the top plate corner 250 and the protrusion 241 have a better fit. At the same time, the flow diversion effect on the outside of the top plate corner 250 is also better. In other alternative embodiments, an arc chamfer may be provided only at the connection between the first corner bend 251 and the second corner bend 252, or only at the connection between the second corner bend 252 and the third corner bend 253, or no arc chamfer may be provided at the connection between the first corner bend 251 and the second corner bend 252 and the connection between the second corner bend 252 and the third corner bend 253. The chamfer shape of the connection is not limited to an arc, and a planar chamfer may also be used.

[0192] In this embodiment, the first corner bend 251, the second corner bend 252 and the third corner bend 253 are integrally formed, and the top plate corner 250 is formed by stamping on the plate. The integral molding method is simple in process and has higher strength, and no seams are formed between the bends, and the waterproof property is better. In other alternative embodiments, the top plate corner 250 can also be integrally formed by mold casting, or the first corner bend 251, the second corner bend 252 and the third corner bend 253 can be assembled by welding or other processes.

[0193] like Fig.10As shown, the side panel 255 has a top panel corner opening groove 256, and the top panel corner opening groove 256 is used to engage with the end portions at both ends of the extension direction of the corresponding protrusion 241, that is, the top panel corner opening groove 256 is used to engage with the step portion 274 of the protrusion 241 to achieve the coordination between the top panel corner 250 and the protrusion 241, prevent relative movement at the connection between the two, and improve the water tightness of the storage panel combination unit.

[0194] The material of the top plate corner 250 can refer to the material that can be selected for the first layer 221 of the top plate 220, such as carbon fiber, polymer composite material or SMC resin material, which can not only meet the strength of the top plate corner 250, but also reduce the weight of the top plate corner 250 and facilitate installation. The top plate corner 250 and the first layer 221 and the second layer 222 can use the same material or different materials.

[0195] like Fig.11 As shown, when the top plate corner 250 is assembled with the top plate storage plate 220, the first corner bend 251 is attached to one end of the side of the protrusion 241 away from the top plate storage plate 220 (the first bend 242 of the protrusion 241), the first corner bend 251 is attached to one end of the side of the protrusion 241 close to the top plate storage plate 220 (the second bend 243 of the protrusion 241), and the second corner bend 252 is attached to the top of the protrusion 241 (the first bend 242 of the protrusion 241). The sides of the top plate corner 250 and the sides of the protrusion 241 are attached to each other, and liquids such as rainwater are difficult to penetrate from the joint between the top plate corner 250 and the protrusion 241, further improving the waterproof effect.

[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 105, storage panel 112, etc. provided by the present invention are also applicable to battery swap stations adopting other structures or layouts.

[0197] Similarly, the storage panel combination unit, frame, storage panel and other structures provided by the present invention are also suitable for energy storage stations with storage and charging functions.

[0198] In this embodiment, the panel assembly unit for the top surface of the battery swap station is different from the panel assembly unit for the side surface. However, in other embodiments, the panel assembly unit for the top surface of the battery swap station can also be used for the side surface, and the panel assembly unit for the side surface of the battery swap station can also be used for the top surface. The two can be selected to use the same panel assembly unit, or the panel assembly units can be interchanged.

[0199] In the description of the present invention, it is necessary to understand that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships of the devices or components during normal use, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
