Description

Technical Field

[0001] The present invention relates to the field of battery swap stations, and in particular to a corner wrap, a storage plate combination unit and a battery swap station or an energy storage station. Background Art

[0002] Now 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 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. Prior art CN203977726U discloses a steel structure factory building colored tile edge drainage structure, the structure is provided with a five-end face combination edge structure at the end face of the colored tile plate, which is composed of an upper end face, a right end face, a lower end face, a bending section 1 and a bending section 2, the bending section 1 is arranged on the left side of the lower end face and is arranged perpendicular to the lower end face, the bending section 2 is arranged perpendicular to the bending section 1, the upper end face, the right end face and the lower end face are arranged perpendicularly, the lower end face is arranged in an arc structure, and in the arc A drain outlet is provided at the lowest point, and a drain pipe is connected to the drain outlet. The lower end surface is provided with a V-shaped structure, which wraps the edge of the colored tile board from the side, and has a certain waterproof effect. However, the upper end surface of the edge is parallel to the upper surface of the colored tile board, and the joint between it and the upper surface of the colored tile board is directly exposed to the outside without a corresponding waterproof mechanism, resulting in water entering the edge and soaking the side edge of the colored tile board, and possibly seeping in along the lower end surface of the edge and the joint of the lower surface of the colored tile board, resulting in poor water tightness. Summary of the invention

[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 1 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 2 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.

[0124] The storage plate assembly unit 111 can be detachably installed on the periphery of the frame 105 .

[0125] like Figure 3 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 1 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. At the same time, the roof panel and warehouse panel 220 at the outermost end of the roof panel and warehouse panel combination units 210 are provided with a roof panel corner 250. Unless otherwise specified, the "warehouse panel" described below refers to the "roof panel and warehouse panel".

[0128] like Fig.15 , Fig.16 As shown, the corner wrap of the battery swap station in this embodiment is arranged at the edge position of one side of the storage plate, and the corner wrap includes a plurality of bent portions, and the plurality of bent portions are interconnected to form a receiving cavity for accommodating the raised portion at one end of the storage plate, and the extension direction of the corner wrap is the same as the extension direction of the raised portion, and the edge portion on one side of the corner wrap extends beyond the edge portion on the other side.

[0129] In this embodiment, the corner is a top plate corner 250, which is arranged at the position of the first end 281 of the storage board at the edge of the top plate 200, and is sleeved on the protrusion 241 of the storage board at the outermost end of the top plate storage board 220 combination unit and wraps the protrusion 241. The top plate corner 250 is formed by connecting multiple corner bending parts, and the multiple corner bending parts 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 sides are in contact with the inner wall of the receiving cavity 254. The edge of the top plate corner 250 on the outward side extends beyond the edge of the inward side opposite to it, and extends along the edge of the outward side of the protrusion 241 and extends to the bottom of the edge of the protrusion 241.

[0130] By setting the top plate corner wrap 250 on the edge of the panel, the corner wrap is raised 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 rainwater trough of the panel, which is convenient for rainwater discharge. At the same time, the corner wrap also covers the side of the panel, which can close the side of the panel, preventing 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 surfaces of the raised portion 241.

[0131] 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.

[0132] like Fig.15 , Fig.16 As shown, the corner includes a first corner bend portion 251, a second corner bend portion 252 and a third corner bend portion 253. The first corner bend portion 251 and the third corner bend portion 253 are respectively connected to two ends of the second corner bend portion 252 to form a trapezoidal cross-section.

[0133] In this embodiment, the first corner bend 251 fits the inner oblique edge (first bend 242) of the protruding portion 241, the second corner bend 252 fits the top (first transition portion 244) of the protruding portion 241, and the third corner bend fits the outer oblique edge (second bend 243) of the protruding portion 241. The three corner bends also form a trapezoidal structure, which is consistent with the shape of the protruding portion 241. This structure also better covers the side of the storage board and fits with the storage board, improving the waterproof performance.

[0134] 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.

[0135] like Fig.15 , Fig.16 As 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; and / or, the inner surfaces of the first corner bend 251, the second corner bend 252 and the third corner bend 253 are in contact with the outer surface of the raised portion 241 of the storage plate.

[0136] In this embodiment, the first corner bend 251 and the second corner bend 252 respectively form an angle greater than 90° with the third corner bend 253. 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 rainwater and other liquids from seeping into the interior of the top plate storage panel 220 from the gap at the connection between the two.

[0137] 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.

[0138] like Fig.15 , Fig.16 As shown, the edge of the third corner bend 253 exceeds the edge of the first corner bend 251 .

[0139] In this embodiment, the edge of the third corner bend 253 exceeds the edge of the first corner bend 251 to form an edge extension 257, and the edge extension 257 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 will 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.

[0140] like Fig.15 , Fig.16 As shown, arc chamfers are provided at the connection between the first corner bending portion 251 and the second corner bending portion 252 and at the connection between the second corner bending portion 252 and the third corner bending portion 253 .

[0141] The arc chamfer can make the connection smoother, and the top plate corner 250 and the raised portion 241 can fit better. At the same time, the flow guidance effect on the outer side of the top plate corner 250 is also better.

[0142] 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 at 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.

[0143] like Fig.15 , Fig.16 As shown, the first corner bending portion 251, the second corner bending portion 252 and the third corner bending portion 253 are integrally formed.

[0144] In this embodiment, the top plate corner 250 is formed by punching on the plate. The one-piece molding method is simple in process, has higher strength, does not form seams between the bent parts, and has better waterproof performance.

[0145] In other alternative embodiments, the top plate corner 250 may be integrally formed by mold casting, or the first corner bend 251, the second corner bend 252 and the third corner bend 253 may be assembled by welding or other processes.

[0146] like Fig.15 As shown, the top plate corner 250 has side panels 255 at both ends along its extension direction. The side panels 255 are formed at both ends of the accommodating cavity, and the side panels 255 are used to cover both ends of the storage plate along the extension direction of the protrusion 241.

[0147] In this embodiment, the side panels 255 cover the ends of both sides of the storage plate, and the raised portions 241 on the edge of the storage plate are entirely wrapped and embedded into the accommodating cavity.

[0148] By closing the corner with the side panel 255, the corner can be entirely covered on the raised portion of the storage board. The side panel covering the side of the raised portion can also enhance the waterproof effect and prevent rainwater from entering through the side gaps between the corner and the storage board.

[0149] like Fig.15 As shown, the side panel 255 has a top panel corner opening groove 256 for engaging with the end portions of the protrusion 241 at both ends of the extension direction.

[0150] In this embodiment, the top plate corner opening groove 256 is used to engage with the step portion 274 of the protrusion 241 to achieve the coordination between the top plate corner 250 and the protrusion 241, prevent relative movement at the connection between the two, and improve the water tightness of the storage panel assembly unit.

[0151] like Fig.14 As shown, the side surface of the top plate storage panel 220 has a step portion 274, and the shape of the top plate corner opening groove 256 matches the step portion 274. The top plate corner opening groove 256 is used to clamp the step portion 274 of the storage panel when assembling with the storage panel.

[0152] The top plate corner wrap 250 and the side surface 237 of the storage plate cooperate with each other through the step portion 274 and the top plate corner wrap opening groove 256, so that the other two ends of the storage plate form a snap-fit ​​structure with the corner wrap.

[0153] The material of the top plate corner 250 can be aluminum alloy, carbon fiber, polymer composite material or SMC resin material.

[0154] In this embodiment, the material of the top plate corner 250 can be the same material as the material of the warehouse plate, which can not only meet the strength of the top plate corner 250, but also reduce the weight of the top plate corner 250, making it easier to install.

[0155] In other embodiments, the top panel corner 250 and the first layer panel 221 and the second layer panel 222 may be made of different materials.

[0156] like Fig.16As shown, the first corner bend 251 fits one end of the protrusion 241 away from the side of the storage plate, the third corner bend 253 fits one end of the protrusion 241 close to the side of the storage plate, and the second corner bend 252 fits the top of the protrusion 241.

[0157] In this embodiment, 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 it is difficult for liquids such as rainwater to penetrate from the joint between the top plate corner 250 and the protrusion 241, thereby further improving the waterproof effect.

[0158] like Figure 4 , Fig.16 As shown, the storage panel combination unit of the present embodiment includes a storage panel 220 and a top corner wrap 250. A plurality of storage panels 220 are combined with each other. The top corner wrap 250 is arranged at the edge of the storage panel 220. The storage panel 220 includes a protrusion 241. The protrusion 241 is arranged at the edge of one side of the storage panel 220. The protrusion 241 protrudes along the surface of the storage panel 220. The protrusion 241 is embedded in the accommodating cavity 254 of the top corner wrap 250. The top corner wrap 250 covers the protrusion 241.

[0159] The top corner 250 is raised along the top surface of the panel 220 and covers the side of the panel 220. The raised structure can guide rainwater to flow out from the edge of the panel 220 or flow into the rainwater trough of the panel 220, which is convenient for rainwater discharge. At the same time, the top corner 250 also covers the side of the panel 220, which can close the side of the panel 220, preventing rainwater from penetrating into the panel 220 from the side of the panel 220 and then penetrating into the battery swap station or energy storage station, and the panel combination unit has better waterproof performance.

[0160] like Figure 5 As shown, the top plate storage plate 220 of the present embodiment 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.

[0161] like Figures 4 to 12 As shown, the first end 281 and the second end 282 are respectively the raised end 240 and the mating end 230 of the top plate warehouse plate 220, the raised end 240 and the mating end 230 are located on both sides of the top plate warehouse plate 220, and multiple top plate warehouse plates 220 are connected to each other through the raised end 240 and the mating end 230, and the raised end 240 and the mating end 230 overlap with each other.

[0162] like Figures 8 to 13 As shown, the top plate warehouse plate 220 includes a first layer plate 221 and a second layer plate 222. The first layer plate 221 protrudes in a direction away from the second layer plate 222 to form a protrusion 241. The edge of the second layer plate 222 is bent and extended toward the first layer plate 221. The edge of the first layer plate 221 is bent and extended toward the second layer plate 222 at the protruding end. 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.

[0163] In this embodiment, the top plate storage panel 220 is a multi-layer composite structure, with the top and bottom formed by 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 away from the second layer 222 to form the raised portion 241, and at the mating end 230, the first layer 221 is raised away from the second layer 222 to form the mating portion 231. The raised portion 241 of the first layer board 221 of the raised end 240 is wrapped by the matching portion 231 of the first layer board 221 of the matching end 230 of the adjacent connected panel to form a stacking structure. This stacking structure can not only play a connecting role, connecting the two ends of the two adjacent panels to form a panel combination unit, but also play a waterproof role. Through the stacking method, the raised end 240 of the top panel panel 220 and the matching end 230 of the adjacent top panel panel 220 are staggered and connected, and the joint of the two panels is wrapped in the raised stacking 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.

[0164] like Fig.16 As shown, the third corner bend portion 253 of the top corner 250 covers the outer surface of the first layer board 221 , and the bottom of the third corner bend portion 253 extends beyond the bottom surface of the second layer board 222 .

[0165] In this embodiment, the bottom of the third corner bend 253 is an edge extension 257. The third corner bend 253 extends in contact with the outer surface of the first layer 221, and the edge extension 257 at the bottom also extends downward in contact with the first layer 221, and finally extends to the bottom of the second layer 222. This can prevent liquid from penetrating into the interior of the storage panel, further improving the waterproofness of the storage panel assembly unit.

[0166] like Figures 7 to 12 As shown, the structure of the first layer board 221 is as follows Fig. 9 As shown, Fig. 9 This is an oblique upward perspective, showing the internal structure of the first layer 221. The raised portion 241 of the first layer 221 is generally in a trapezoidal structure, and is formed by connecting two bent portions. Fig.10, the first layer 221 first bends upward toward the edge and extends to form a first bending portion 242. When the first bending portion 242 extends to the highest point, it extends outward in the horizontal direction to form a first transition portion 244. At the farthest end of the first transition portion 244, the first layer 221 extends obliquely downward in the figure to form a second bending portion 243. The first bending portion 242 and the second bending portion 243 form two oblique sides of the trapezoid, and the first transition portion 244 constitutes the top side of the trapezoid. 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 bending portion 232 and a fourth bending portion 233 as two oblique sides, and a second transition portion 234 as the top side. When mating, 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 protrusion 241 and the matching portion 231 are trapezoidal protrusions, which can not only cover the joints of the storage panels, but also play a role in diversion, so that rainwater at the joints can flow down along the inclined 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.

[0167] 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.

[0168] like Figures 8 to 10 As shown, the connection between the first bend portion 242 and the second bend portion 243 and the first transition portion 244 has an arc chamfer, and the connection between the third bend portion 232 and the fourth bend 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 overlapped state, further improving the water tightness.

[0169] like Figure 8 As 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.

[0170] like Figure 8 As shown, in the stacked structure, there is a hollow cavity between the first layer board 221 and the second layer board 222 .

[0171] like Figure 8As 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.

[0172] like Figures 8 to 12 As shown, 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.

[0173] like Figure 8-10 As shown, a sealing strip 246 is provided on the top of the raised portion 241 , and the sealing strip 246 abuts against the raised portion 241 and the top corner 250 , respectively.

[0174] In this embodiment, the top of the protrusion 241 has a groove 245 along the extension direction of the storage plate, and a sealing strip 246 is installed in the groove 245. One side of the sealing strip 246 is stuck in the groove 245, and the other side is against the inner side of the top of the top corner 250.

[0175] In this embodiment, the sealing strip 246 is also arranged between the top of the raised part 241 and the top of the matching part 231. When rainwater accumulates on the storage panel assembly unit and causes water to rise from the gap between the raised part 241 and the matching part 231, it is blocked by the sealing strip 246 arranged at the top and cannot flow over the raised part 241 and penetrate into the battery swap station or energy storage station from the joint between the raised part 241 and the matching part 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.

[0176] In other embodiments, a sealing strip may be provided between the first bending portion 242 and the fourth bending portion 233 , and a sealing strip may be provided between the second bending portion 243 and the third bending portion 232 .

[0177] like Figures 4 to 14 As shown, the top plate storage plate 220 has side portions 237 at both ends along the extension direction of the protrusion 241, and the side portions 237 are used to cover the gap between the first layer plate 221 and the second layer plate 222, and form a hollow cavity with the first layer plate 221 and the second layer plate 222.

[0178] In this embodiment, the protruding end 240 and the mating end 230 of the storage plate are respectively located at the opposite first end 281 and the second end 282, 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 plate and is used to close the third end 283 and the fourth end 284 of the storage plate.

[0179] like Fig.14 As shown, the side portion 237 has a first side portion 271 and a second side portion 272. The end surface of the step portion 274 of the top plate storage plate 220 is located in the same plane as the second side portion, and the first side portion 271 has a bottom plate 275, and the step portion 274 is formed on the 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 portion 272.

[0180] In this embodiment, the part of the side surface portion 237 located at the protruding 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. The second side surface portion 272 covers part of the outer side of the first side surface portion 271 of the adjacent storage plate. The first side surface portion 271 is spliced ​​and wrapped so that the seams of the two are staggered to prevent liquid from penetrating into the storage plate from the seams on the sides of the two storage plates.

[0181] like Fig.14 As shown, 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 Fig. 9 ), 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.

[0182] This embodiment provides a form of engaging the side surfaces of two adjacent storage panels, but the present invention is not limited thereto.

[0183] 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.

[0184] like Fig.17 As shown, the top plate corner opening groove 256 of the side panel 255 of the top plate corner 250 is engaged with the side surfaces of the top plate storage panel 220 at both ends along the extension direction of the protrusion 241.

[0185] In this embodiment, as shown above, the top plate corner opening groove 256 can also cooperate with the step portion 274 of the top plate storage panel 220. The top plate corner 250 and the side portion 237 of the top plate storage panel 220 cooperate with each other through the step portion 274 and the top plate corner opening groove 256, so that the other two ends of the storage panel and the top corner 250 form a snap-fit ​​structure, preventing the relative movement of the connection between the storage panels and improving the water tightness of the connection between the storage panels.

[0186] like Figure 4 , Fig.14 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.

[0187] like Figure 8 , Fig.11 and Fig.13 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.

[0188] 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.

[0189] like Fig.18 As shown, the assembly part 260 of this embodiment is a buckle, including 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 layer board 222. Fig.18As 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 layer 222, and the assembly hole 261 in the column 224 from bottom to top, thereby fixing the snap-fit ​​on the top plate warehouse plate 220. The snap-fit ​​portion 620 of the snap-fit ​​is located on the outside of the second layer 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 222 can be replaced by other structures that can realize the connection between the top plate warehouse plate 220 and the frame 105 or other internal equipment of the battery swap station.

[0190] This embodiment provides a buckle form, but the present invention is not limited thereto, and other existing buckle forms may also be used.

[0191] like Figure 8 , Fig.11 and Fig.13 As shown, 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.

[0192] 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.

[0193] like Figure 8 , Fig.13 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.

[0194] like Figure 8 , Fig.11 and Fig.13 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.

[0195] like Figure 8 , Fig. 9 and Fig.11As shown, the storage board of this embodiment also includes a plurality of first connecting columns 225 and second connecting columns 226. The structures of the first connecting columns 225 and the second connecting columns 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 columns 225 and the second connecting columns 226. The first connecting columns 225 and the second connecting columns 226 are arranged between the first layer 221 and the second layer 222. The first connecting columns 225 are arranged on the first layer 221 and extend toward the second layer 222. The second connecting columns 226 are arranged on the second layer 222 and extend toward the first layer 221.

[0196] 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.

[0197] 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.

[0198] 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.

[0199] 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.

[0200] In other embodiments, only one or two of the three types of connection column settings may be included.

[0201] like Figure 8 , Fig. 9 and Fig.11As shown, 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 is simple in process, more convenient in assembly and manufacturing, 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.

[0202] like Figure 8 , Fig. 9 and Fig.11 As shown, the first connecting column 225 and the second connecting column 226 of this embodiment are integrally molded and cast with the warehouse 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 method of warehouse board has simple process and higher strength.

[0203] 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.

[0204] like Figure 7 , Figure 8 and Fig.13 As shown, the storage panel also 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.

[0205] In other embodiments, conventional thermal insulation materials such as rock wool or polyurethane foam may also be used.

[0206] like Figure 7 , Figure 8 and Fig.13 As shown, the thermal 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 plate 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 thermal insulation layer 223, the first layer 221 and the second layer 222. The first layer 221, the second layer 222 and the thermal insulation layer 223 form a sandwich structure, and the first layer 221 and the second layer 222 are located on both sides of the thermal insulation layer 223, and the thermal 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 thermal insulation layer 223 by the connecting column passing through the middle, so that the strength of the storage plate itself is better.

[0207] 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.

[0208] like Figures 4 to 14 As shown, the first layer board 221 and the second layer board 222 of this embodiment are made of SMC resin material.

[0209] 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.
