[0003] 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 the replacement of batteries or charging new energy vehicles and meet the battery replacement needs of new energy vehicles, it is necessary to build battery replacement stations or energy storage stations. With the rapid popularization of new energy vehicles, more battery replacement stations or energy storage stations need to be built to meet the demand. If traditional construction methods are used for construction, not only the cost is high and the construction period is long, but it is also not conducive to later expansion and upgrading of battery replacement equipment. In the prior art, CN103669925A discloses a steel structure charging and swapping station, including a rigid frame and a side sealing plate, a top plate, a door plate and a bottom plate that are detachably fixed on the rigid frame by fasteners. The waterproofness and structural strength of the charging and swapping station of the above structure are defective. Summary of the invention

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

[0006] The present invention provides a battery swap station or energy storage station, which includes a frame, a top plate and a side plate, wherein the top plate is detachably mounted on the top surface of the frame, and the side plate is detachably mounted on the outer side surface of the frame; the top plate includes a plurality of storage panels spliced ​​in a horizontal direction; the storage panels of the top plate are provided with a protruding end and a mating end at opposite ends along a first direction, respectively, the protruding end and the mating end both protrude outward from the same side surface of the storage panel of the top plate and extend in the same direction, a protruding cavity is formed in the mating end, and the protruding cavity in the mating end is used to accommodate the protruding end of the storage panel of the adjacent top plate.

[0007] In this solution, a battery swap station or energy storage station is constructed by detachably installing the top plate and side plates on the frame, which is convenient for modular station construction. It not only has low construction cost and short construction period, but also is conducive to later maintenance and transformation. With the above-mentioned structural form, the raised end and the mating end are used to control the rainwater to be discharged from the top plate from both ends of the extension direction of the raised end and the mating end, so as to prevent the rainwater from penetrating into the interior of the panel from the connection between the panels in the top plate. The instantaneous rainfall needs to at least overflow the highest point of the raised end or the mating end 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 and the mating end can guide the rainwater to flow downward, which is convenient for the timely discharge of the rainwater. At the same time, the structural strength of the top plate is improved by the superimposed and mating structure of the raised end and the mating end, so as to meet the strength requirements and waterproof requirements of the battery swap station or energy storage station.

[0008] Preferably, the edge of the top plate extends horizontally beyond the outer surface of the side plate, and / or the edge of the top plate extends vertically downward beyond the top edge of the side plate. In this solution, the battery swap station or energy storage station adopts the above structure to prevent rainwater from penetrating into the interior of the battery swap station or energy storage station from the connection gap between the top and the side plate, thereby improving the waterproof function of the battery swap station or energy storage station and preventing rainwater from penetrating into the battery swap station or energy storage station during heavy rainfall, causing damage to the battery swap equipment and charging equipment.

[0009] Preferably, a seal is provided at the connection between the top plate and the side plate. In this solution, by providing a seal at the connection between the top plate and the side plate, the airtightness of the battery swap station or energy storage station is enhanced to avoid the temperature inside the battery swap station or energy storage station being too high or too low due to the external ambient temperature, which affects the battery charging and discharging performance and the service life of the equipment. At the same time, the waterproof function of the battery swap station or energy storage station is improved to avoid rainwater from penetrating into the battery swap station or energy storage station during heavy rainfall, causing damage to the battery swap equipment and charging equipment.

[0010] Preferably, the top plate includes multiple panels joined horizontally, and the side plates include multiple panels joined vertically. In this solution, the top plate and the side plates are joined by panels, which effectively shortens the construction period and cost of the battery swap station or energy storage station, makes the construction convenient and fast, reduces the transportation cost, and facilitates on-site assembly of the battery swap station or energy storage station.

[0011] Preferably, the plurality of top plate storage panels form a single row structure in the horizontal direction. In this solution, the top plate storage panels adopt the above-mentioned splicing method, which is simple and fast, and can greatly improve the installation speed of the top plate.

In this solution, the above-mentioned structural form is adopted to further prevent rainwater from penetrating into the interior of the battery swap station or energy storage station from the connection between the top and the side plates of the battery swap station or energy storage station, thereby improving the waterproof function of the battery swap station or energy storage station and preventing rainwater from penetrating into the battery swap station or energy storage station during heavy rainfall, causing damage to the battery swap equipment and charging equipment.

[0014] In this solution, the above-mentioned structural form is adopted, and the raised end and the mating end are used to control rainwater to be discharged from the top plate from both ends of the extension direction of the raised end and the mating end, so as to prevent rainwater from penetrating into the interior of the panels from the connection points of the panels in the top plate. The instantaneous rainfall needs to at least overflow the highest point of the raised end or the mating end before it can flow to the connection point between the two, thereby enhancing the waterproof effect. Moreover, even if the rainwater overflows the highest point, the raised end and the mating end 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 top plate is improved by the superimposed and mating structure of the raised end and the mating end, so as to meet the strength requirements and waterproof requirements of the battery swap station or energy storage station. The side portion covers the two side edges of the panel to prevent liquid from penetrating into the panel from the side of the panel, thereby preventing liquid from entering the interior of the battery swap station or energy storage station.

In this solution, the above-mentioned structural form is adopted, and the protruding end of the adjacent panel is covered by the mating end of the panel, and a covering structure is formed from the first direction and the second direction, thereby improving the connection strength between adjacent panels and further preventing rainwater from penetrating into the interior of the battery swap station or energy storage station from the connection between the top panel and the side panel.

[0016] Preferably, the top panel comprises a first layer and a second layer, a plurality of columns are provided between the first layer and the second layer, and the first layer and the second layer are fixedly connected by the columns.

The assembly hole is connected to the outside of the second layer of the board through the through hole, and the assembly hole is used to install an assembly part.

The assembly part can be a buckle or other connecting mechanism, and the assembly hole is not directly provided on the surface of the warehouse board. Instead, by providing the assembly hole in the column inside the warehouse board, the strength of the warehouse board will not be affected. The strength of the warehouse board is higher, and deformation of the warehouse board due to excessive local force during use is avoided, thereby improving the overall strength of the battery swap station or energy storage station.

When the two boards are connected, the matching portion of the storage board will cover and sleeve on the upper side of the raised portion of the other storage board to form a superimposed structure. The connection and fixation through the middle connecting column can make the strength of the top plate higher. The connecting column is provided in the cavity of the raised portion, with a larger space and a longer length, which improves the structural strength of the cavities of multiple storage boards. It can also cover the connection gap between the two storage boards to prevent liquid from penetrating from the gap, making the water tightness of the storage board combination unit better.

In this solution, the raised end of the top plate extends upward and the lowered first plate is attached to each other, which can seal the inner cavity of the raised part to prevent water from penetrating into the top plate.

In this scheme, the first layer of plate at the mating end extends along the shape of the protrusion of the protrusion of the storage panel adjacent to the top plate and wraps the protrusion to achieve the connection between the mating end and the protrusion, thereby improving the connection strength. At the same time, the edge of the first layer of plate at the mating end fits the outer surface of the side of the protrusion away from the mating part. By bending the first layer of plate and the second layer of plate at the mating end of the storage panel to form a structure in which the upper and lower layers are joined, the edge of the mating part forms a sealing structure to prevent rainwater from penetrating into the interior of the storage panel from the junction of the first layer of plate and the second layer of plate.

DETAILED DESCRIPTION

[0077] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0078] like Figure 1 and Figure 2As shown, a battery swap station is illustrated according to an embodiment of the present invention. The battery swap station includes a battery swap room 40 and at least one charging room 30 respectively arranged on one side of the battery swap room 40. The battery swap station may also include a monitoring room, a storage room, etc. The battery swap room 40 is used to carry vehicles whose battery packs are to be replaced. The vehicles drive into and dock at the battery swap room 40. 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 battery packs from the vehicle, the battery swap cart transports them to the charging room 30 for charging. Charging racks, elevators, main control boxes and other equipment are placed in the charging room 30. 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 swap cart, and to take the battery packs out of the charging rack or put them into the charging rack.

[0079] Specific as Figure 2 As shown, a charging rack 31, a lift 32, a main control box 33 and other equipment are placed in the charging room 30. The charging rack 31 is used to accommodate battery packs and charge old battery packs. The lift 32 is used to exchange battery packs with the battery swapping vehicle, and to take the battery packs out of the charging rack 31 or put them into the charging rack 31. At least two rows of charging racks 31 are arranged side by side in the charging room 30 perpendicular to the driving direction of the vehicle. The lift 32 is arranged in the lifting area 34 between the two rows of charging racks 31. The main control box 33 is arranged on one side of the charging room 30 close to the battery swapping room 30. The main control box 33 is used to control the electrical equipment in the battery swapping station.

[0080] like Figure 1 As shown, the battery swap station of this embodiment is formed of a supporting structure by multiple frames and is divided into multiple functional rooms such as a charging room 30, a monitoring room, a storage room, etc., and the top of the frame is covered with a top plate 10, and the side of the frame is covered with a side plate 20. A door 50 for personnel and equipment to enter and exit is opened on the wall of the charging room 30 of the battery swap station. Figure 1 As shown, the battery swap station includes a frame, a top plate 10 and a side plate 20. The top plate 10 can be detachably mounted on the top surface of the frame, and the side plate 20 can be detachably mounted on the outer side of the frame. By detachably mounting the top plate 10 and the side plate 20 on the frame to build the battery swap station, modular construction is facilitated, which not only has low construction costs and a short period of time, but is also conducive to later maintenance and renovation.

[0081] In this embodiment, the edge of the top plate 10 extends beyond the outer surface of the side plate 20 in the horizontal direction. Specifically, the side plate 20 has a first end and a second end in the longitudinal direction, the second end of the side plate 20 is close to the top plate 10 relative to the first end of the side plate 20, and the edge of the top plate 10 extends beyond the outer side surface of the second end of the side plate 20 in the horizontal direction. The above structure is adopted to prevent external liquid from directly penetrating into the battery swap station from the gap at the connection between the storage plates. In other embodiments, the edge of the top plate 10 is extended downward in the vertical direction beyond the top edge of the side plate 20. That is, the edge of the top plate 10 extends downward in the vertical direction beyond the upper end surface of the second end of the side plate 20. In some more preferred embodiments, while the edge of the top plate 10 extends beyond the outer surface of the side plate 20 in the horizontal direction, the edge of the top plate 10 extends downward in the vertical direction beyond the top edge of the side plate 20. That is, the edge of the top plate 10 extends downward in the vertical direction beyond the upper end surface of the second end of the side plate 20 and extends in the horizontal direction beyond the outer side surface of the second end of the side plate 20. The arrangement of the top plate 10 and the side plate 20 described above can prevent rainwater from penetrating into the interior of the battery swap station from the connection gap between the top plate and the side plate, thereby improving the waterproof function of the battery swap station and preventing rainwater from penetrating into the battery swap station during heavy rainfall, thereby damaging the battery swap equipment and charging equipment.

[0082] In this embodiment, a seal is provided at the connection between the top plate 10 and the side plate 20. By providing a seal at the connection between the top plate 10 and the side plate 20, the airtightness of the battery swap station is enhanced. The top plate 10 and the side plate 20 are used to isolate the inside and outside of each functional room of the battery swap station, preventing external rainwater, dust and other impurities from entering the interior of the battery swap station and causing damage to electrical components in the battery swap station, such as charging racks and main control boxes. At the same time, the waterproof function of the battery swap station is improved to prevent rainwater from penetrating into the battery swap station during heavy rainfall, causing damage to the battery swap equipment and charging equipment.

[0083] like Figure 1As shown, in this embodiment, the top plate 10 includes a plurality of panels spliced ​​in the horizontal direction (hereinafter, the panel of the top plate 10 is referred to as the "top panel"). The side panel 20 is formed by splicing a plurality of panels in the horizontal and longitudinal directions in the vertical direction (hereinafter, the panel of the side panel 20 is referred to as the "side panel"). The side panel has a first end and a second end arranged opposite to each other in the longitudinal direction. Among the plurality of side panels spliced ​​in the longitudinal direction, the first end of the upper side panel covers the second end of the lower side panel. The side panels are staggered when connected, so that the sides of the plurality of side panels can overlap each other when spliced, so that the connection gaps between the side panels will not directly conduct to the inside of the battery swap station, so that the water tightness is better, and the external liquid is prevented from directly penetrating into the battery swap station from the gaps at the connection of the panels. The top plate 10 and the side panels 20 adopt the panel splicing method, which effectively shortens the construction period and construction cost of the battery swap station, is convenient and quick to build, reduces the transportation cost, and facilitates the on-site assembly of the battery swap station. Among them, in this embodiment, a plurality of top panels form a single-row structure in the horizontal direction. The top warehouse plate adopts the above-mentioned splicing method, which is simple and fast, and can greatly improve the installation speed of the top plate 10.

[0084] The frame of the battery swap station is provided with a card slot, and buckles are installed on the sides of the top and side panels facing the frame, and the top and side panels are fixed to the card slots of the frame through buckles. The top and side panels are connected to the card slots on the frame of the battery swap station through buckles, making the panels easy to install. At the same time, the use of such panels can improve the strength of the top and side surfaces of the battery swap station, making the battery swap station stronger and more adaptable to the environment.

[0085] Combine the following Figure 3-10 The structure of a top panel 100 used in the battery swap station in this embodiment is described in detail. Figure 3-7 As shown, in this embodiment, the top warehouse panel 100 includes a first layer panel and a second layer panel. In this embodiment, for the convenience of distinction, according to the spatial position of the top warehouse panel 100, the first layer panel of the top warehouse panel 100 is called the upper layer panel 101, and the second layer panel is called the lower layer panel 102. A plurality of columns are arranged between the upper layer panel 101 and the lower layer panel 102, and the upper layer panel 101 and the lower layer panel 102 are fixedly connected by the columns, and an insulation layer 103 is arranged between the upper layer panel 101 and the lower layer panel 102. The top warehouse panel 100 connects the upper layer panel 101 and the lower layer panel 102 through the columns, which increases the overall strength of the top warehouse panel 100. At the same time, the insulation layer 103 is arranged between the upper layer panel 101 and the lower layer panel 102, which has the function of heat insulation and reduces heat transfer, so that the overall strength and insulation requirements of the battery swap station can be guaranteed.

[0086] In this embodiment, the material of the thermal insulation layer 103 is one or more combinations of inorganic foaming materials, rock wool, polyurethane foam or aerogel felt. The material of the thermal insulation layer 103 in this embodiment includes aerogel felt, which includes aerogel and glass fiber felt, and the aerogel is dispersed in the glass fiber felt. The use of glass fiber as a container for aerogel makes the aerogel felt high in strength, good in fireproofing effect, and not easy to damage. The thermal insulation layer 103 of the top warehouse panel 100 adopts the above materials, so that the top warehouse panel 100 has good heat insulation and thermal insulation effects. By adding aerogel felt to the thermal insulation layer 103, the fireproof function of the top warehouse panel 100 can be improved.

[0087] In this embodiment, the material of the upper plate 101 and the lower plate 102 of the top warehouse plate 100 is one or more combinations of SMC, carbon fiber or polymer composite materials. SMC composite materials are preferably used. SMC composite materials have excellent electrical insulation properties, mechanical properties, thermal stability, and chemical corrosion resistance. The SMC composite material is a sheet-shaped molded material formed by unsaturated polyester resin, reinforcing materials and auxiliary materials, which is formed by cutting and molding. In other embodiments, the upper plate 101, the lower plate 102 and the insulation layer 103 of the top warehouse plate 100 can also be other materials with excellent performance, which will not be repeated here.

[0088] In this embodiment, the column is made of resin material. The column is made of resin material, which is convenient for processing and molding, while reducing the weight of the top warehouse plate 100, making the top warehouse plate 100 lightweight and convenient for transportation and installation. Among them, the resin is preferably unsaturated polyaldehyde resin. Before placing the insulation layer 103 between the upper plate 101 and the lower plate 102, a through hole is pre-opened in the thickness direction of the insulation layer 103 to facilitate the column to pass through the through hole. By providing a through hole on the insulation layer 103, it is convenient for the column to pass through, avoiding re-drilling during construction, and improving the production efficiency of the top warehouse plate 100.

[0089] like Figure 5-7 As shown, in this embodiment, the column includes a first connecting column 105 and a second connecting column 106, a plurality of first connecting columns 105 are provided on the upper plate 101, and a plurality of second connecting columns 106 are provided on the lower plate 102. Among them, some of the second connecting columns 106 are fixedly abutted against some of the first connecting columns 105, some of the first connecting columns 105 are fixedly abutted against the lower plate 102, and some of the second connecting columns 106 are fixedly abutted against the upper plate 101. By arranging the column on the upper plate 101 and the lower plate 102, the strength of the upper plate 101 and the lower plate 102 can be increased, thereby increasing the overall strength of the top warehouse plate 100. The first connecting column 105 and the second connecting column 106 can be connected and fixed by gluing, clamping, beads, etc. The connection method of the connecting column is simple in process, more convenient in assembly and manufacturing, and has a good fixing effect.

[0090] In this embodiment, the first connecting column 105 and the second connecting column 106 are connected and fixed to the upper plate 101, the lower plate 102, or each other by gluing. In other embodiments, the first connecting column 105 and the second connecting column 106 can also be connected and fixed by snapping, beads or other conventional connection methods, as long as the connection strength meets the requirements. In other embodiments, a plurality of columns can be provided only on the upper plate 101, and the columns are fixed in abutment with the lower plate 102. Alternatively, a plurality of columns can be provided only on the lower plate 102, and the columns are fixed in abutment with the upper plate 101. By providing columns on the upper plate 101 or the lower plate 102, the strength of the upper plate 101 or the lower plate 102 and the strength of the entire top warehouse plate 100 can also be increased. In this embodiment, the first connecting column 105 is integrally formed with the upper plate 101. The second connecting column 106 is integrally formed with the lower plate 102. The above-mentioned molding method is not only convenient for processing, but also can reduce the installation process, reduce the installation difficulty, and improve the connection strength between the upper plate 101 and the lower plate 102.

[0091] In this embodiment, the material of the upper plate 101 and the lower plate 102 of the top warehouse plate 100 is made of SMC composite material, and the column is made of resin, which is convenient for injection molding. When preparing the upper plate 101 or the lower plate 102, the mold hole of the first connecting column 105 or the second connecting column 106 is directly reserved in the mold to achieve one-time molding. This method of the top warehouse plate 100 has a simple process and higher strength. In other embodiments, the first connecting column 105 and the second connecting column 106 can also be installed on the upper plate 101 or the lower plate 102 by welding, gluing, etc. Of course, the column can also be other types of materials. For example, if the upper plate 101 or the lower plate 102 of the top warehouse plate 100 is made of metal or carbon fiber material, the column can also be made of metal or carbon fiber material accordingly.

[0092] The top panel 100 in this embodiment is used to be installed on the top of the battery swap station, and multiple top panels 100 are assembled and spliced ​​into the top panel 10 of the battery swap station. The upper panel 101 of the top panel 100 serves as the upper top layer of the top panel 10, and the lower panel 102 serves as the lower top layer of the top panel 10. The lower panel 102 is fixedly mounted on the frame of the battery swap station. In this embodiment, in order to facilitate drainage, the upper panel 101 has a plurality of raised units on the surface away from the lower panel 102, and the plurality of raised units extend along the first direction of the upper panel 101 and are arranged at intervals along the second direction of the upper panel 101, and the first direction is perpendicular to the second direction. By arranging the raised units on the surface of the upper panel 101 away from the lower panel 102, not only the strength of the upper panel 101 is increased, but also drainage is facilitated. The raised units extending along the first direction of the upper panel 101 are not parallel to the first direction, as long as they are roughly parallel or the angle with the first direction is within 45°.

[0093] In this embodiment, the protruding units at the two ends of the second direction of the upper plate 101 are respectively the protruding portion 111 and the matching portion 121, and the middle protruding unit is the middle protrusion 140, and the protruding portion 111 and the matching portion 121 are both higher than the middle protrusion 140. The above-mentioned structural form is adopted to prevent the depth of water accumulation on the outer surface of the top warehouse plate 100 from overflowing the gap at the connection of the two top warehouse plates 100 and entering between the upper plate 101 and the lower plate 102 when the rain is too heavy, causing water accumulation inside the top warehouse plate 100, affecting the normal use of the top warehouse plate 100. In other embodiments, the outer surface of the upper plate 101 can also be provided with protruding units only at the two ends, and the middle part is a flat plate structure. Alternatively, the outer surface of the upper plate 101 can also be set to other structures that are conducive to drainage or increase the strength of the top warehouse plate 100.

[0094] In this embodiment, the protruding units formed on the outer surface of the upper plate 101 are formed by the inner surface of the upper plate 101 being recessed outward. The inner surface of the upper plate 101 is recessed outward so that a plurality of outwardly protruding cavities corresponding to the protruding units are formed on the inner surface of the upper plate 101 close to the lower plate 102. The upper plate 101 adopts the above-mentioned structural form to form a corrugated board structure, which can further increase the structural strength of the upper plate 101. Of course, in other embodiments, the middle protrusion 140 of the upper plate 101 can be a solid structure, that is, the area on the inner surface of the upper plate 101 corresponding to the middle protrusion 140 is a planar structure without a cavity.

[0095] like Figure 6 As shown, in the present embodiment, a part of the first connecting column 105 provided on the upper plate 101 is provided in the cavity, and a part is provided outside the cavity. The first connecting column 105 is provided in the cavity of the protrusion 111, so as to improve the structural strength of the protrusion unit of the upper plate 101, and also improve the connection strength at the connection of the multiple top warehouse plates 100. In other embodiments, the first connecting column 105 may not be provided in the cavity, but the second connecting column 106 may be provided at a position corresponding to the cavity on the lower plate 102, and the other end of the second connecting column 106 abuts against the inner surface of the cavity. Alternatively, in other embodiments, the first connecting column 105 is only provided in the cavity on the inner surface of the upper plate 101. When arranging the first connecting column 105, it is best to evenly distribute it on the inner surface of the upper plate 101. The specific arrangement method can be adjusted according to actual needs and will not be described in detail here.

[0096] In this embodiment, the column also includes an assembly column 104, and the assembly column 104 is fixed on the lower plate 102. An assembly hole (not shown in the figure) is provided in the assembly column 104, and an assembly part 150 is installed in the assembly hole. The top warehouse plate 100 is installed on the frame of the battery swap station, such as the column 70 of the battery swap station, through the assembly part 150, which facilitates the modular disassembly and assembly of the top warehouse plate 100 and the frame, and further improves the overall strength of the battery swap station. A through hole is provided on the lower plate 102, and the assembly hole is connected to the outside of the lower plate 102 through the through hole. Mounting holes are also provided on the frame at positions corresponding to the through holes on the lower plate 102. During assembly, the assembly part 150 passes through the mounting hole and the through hole on the lower plate 102 to enter the assembly hole, and then the top warehouse plate 100 is installed on the frame. The assembly part 150 can be a structure such as a bolt or a buckle. By providing assembly holes for connecting the assembly parts 150 on the columns of the lower plate 102, the assembly of the top warehouse plate 100 with other components can be facilitated and the strength of the connection can be increased.

[0097] like Fig.11 As shown, the assembly part 150 of this embodiment is a buckle, including a first connecting part 151 and a first clamping part 152. The first clamping part 152 is provided with a through hole for the first connecting part 151 to pass through. The first connecting part 151 of the buckle in this embodiment is a bolt, and the first connecting part 151 passes through the through hole on the first clamping part 152 to achieve fixation with the lower plate 102. The first connecting part 151 passes through and screws into the through hole on the first clamping part 152, the through hole on the lower plate 102 and the assembly hole on the assembly column 104 from bottom to top, thereby fixing the buckle on the top warehouse plate 100. The first clamping part 152 of the buckle is located on the outer side of the lower plate 102 (the side facing the inside of the battery swap station), and is used to connect with the frame or other internal equipment of the battery swap station.

[0098] In other alternative embodiments, the assembly holes and the through holes on the lower plate 102 can be replaced with other structures that can connect the top panel 100 to the frame or other internal equipment of the power station. In other embodiments, the assembly holes can also be replaced with other conventional connection structures, and the assembly parts 150 can be replaced with other conventional connection structures.

[0099] The top panel 100 of the top panel 10 has relative raised ends 110 and mating ends 120 along the splicing direction. The edges of the raised ends 110 and the mating ends 120 extend beyond the outer surface of the side panels 20 in the horizontal direction, and the edges of the raised ends 110 and the mating ends 120 extend beyond the top of the side panels 20 in the vertical direction. The top panel 100 of the top panel 10 adopts the above-mentioned structural form to further prevent rainwater from penetrating into the interior of the battery swap station from the connection between the top and the side panels of the battery swap station, thereby improving the waterproof function of the battery swap station and preventing rainwater from penetrating into the battery swap station during heavy rain, causing damage to the battery swap equipment and charging equipment.

[0100] like Figure 1 , Figure 8 and Fig. 9 As shown, the top plate 10 covering the top surface of the battery swap station is formed by connecting a plurality of top warehouse panels 100. When connected, the first end of a top warehouse panel 100 is matched and connected with the second end of an adjacent top warehouse panel 100. In this embodiment, the first end is called a raised end 110, and the second end is called a matching end 120. The plurality of top warehouse panels 100 are connected to each other through the raised end 110 and the matching end 120, and the raised end 110 and the matching end 120 overlap each other. The top warehouse panel 100 is a multi-layer composite structure, and the top and bottom are formed by an upper plate 101 and a lower plate 102. At the raised end 110 and the matching end 120, the upper plate 101 is bent to form a raised portion 111 and a matching portion 121 of corresponding shapes.

[0101] At the raised end 110 of the top warehouse plate 100, the upper plate 101 is raised away from the lower plate 102 to form a raised portion 111. The raised portion 111 has a cavity in it, and a connecting column is provided in the cavity to connect and fix the lower plate 102 opposite to the raised portion. At the mating end 120 of the top warehouse plate 100, the upper plate 101 is raised away from the lower plate 102 to form a mating portion 121, and the mating portion 121 is used to cover the outer side of the raised portion 111 of the adjacent top warehouse plate 100. The raised portion 111 of the upper plate 101 at the raised end 110 is covered in the mating portion 121 of the upper plate 101 at the mating end 120 of the top warehouse plate 100 connected thereto to form a superimposed structure, which can not only play a connecting role, connecting the adjacent top warehouse plates 100 through the raised end 110 and the mating end 120 to form the top plate 10, but also play a waterproof role. The raised ends 110 and the mating ends 120 of two adjacent top warehouse panels 100 are overlapped and connected, so that water cannot directly penetrate into the joint from the outside of the top warehouse panels 100, thereby improving the water tightness of the connection between the top warehouse panels 100.

[0102] like Fig. 9 As shown, the raised portion 111 of the upper plate 101 is roughly in a trapezoidal structure, which is connected by three bends. The outer end of the upper plate 101 is tilted upward and extends to form a first bend portion 112. When the first bend portion 112 extends to the highest point, it extends outward in the horizontal direction to form a first transition portion 114. At the farthest end of the first transition portion 114, the upper plate 101 extends obliquely downward to form a second bend portion 113. The first bend portion 112 and the second bend portion 113 constitute the two oblique sides of the trapezoid, and the first transition portion 114 constitutes the top side of the trapezoid. The matching portion 121 of the upper plate 101 is also in a trapezoidal structure, and its shape matches that of the raised portion 111. It also has a third bend portion 122 and a fourth bend portion 123 as two oblique sides, and a second transition portion 124 as the top side.

[0103] When mating, the mating portion 121 covers and overlaps the protrusion 111 of the adjacent top panel 100. In this embodiment, both the protrusion 111 and the mating portion 121 are protrusions of a trapezoidal structure and overlap and cover each other, which not only improves the structural strength of the connection of the top panel 100, but also the protrusion structure can play a role in diversion, so that rainwater at the joint can flow down along the inclined side of the trapezoid to avoid accumulation and cause rainwater to penetrate into the top panel 100 from the joint. At the same time, the top side of the trapezoid is a plane, which can also be used to install other components.

[0104] In other embodiments, the raised portion 111 and the mating portion 121 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 adjacent top warehouse panels 100 overlap each other.

[0105] like Fig. 9 As shown, the connection between the first bending portion 112, the second bending portion 113 and the first transition portion 114 is chamfered in an arc shape, and the connection between the third bending portion 122 and the third connecting portion and the second transition portion 124 is also chamfered in an arc shape. This structure can increase the strength of the connection, facilitate rainwater to flow down from the second transition portion 124 to both sides, and at the same time make the protrusion 111 and the matching portion 121 more closely fit in the overlapping state, further improving the water tightness. Fig. 9 As shown, the outer wall of the first bend 112 of the raised portion 111 fits the inner wall of the fourth bend 123 of the matching portion 121. This can play a waterproof role and prevent the water level from rising when the power swap station is in a rainy state and seeping into the top warehouse plate 100 through the gap. Fig. 9 As shown, at the overlapping structure of the protrusion 111 and the matching portion 121, there is a gap between the upper plate 101 and the lower plate 102. At the protrusion end 110 of the top plate 100, the edge of the lower plate 102 is bent toward the upper plate 101, and the edge of the upper plate 101 is bent toward the lower plate 102. The inner surface of the edge of the upper plate 101 is attached to the outer surface of the edge of the lower plate 102. The above structure forms a staggered structure to close the inner cavity of the protrusion between the upper plate 101 and the lower plate 102.

[0106] For example Fig. 9As shown, at the mating end 120 of the top warehouse plate 100, the edge of the upper plate 101 is bent and extended from the side of the protrusion 111 of the adjacent top warehouse plate 100 close to the mating end 120 to the side of the protrusion 111 away from the mating end 120, and the inner surface of the edge of the upper plate 101 fits the outer surface of the side of the protrusion 111 away from the mating end 120. The edge of the lower plate 102 is bent and extended toward the upper plate 101, and the edge of the lower plate 102 is sandwiched between the edge of the upper plate 101 and the side surface of the protrusion 111 of the adjacent top warehouse plate 100 close to the mating end 120. The outer surface of the edge of the lower plate 102 simultaneously fits the outer surface of the edge of the upper plate 101 of the protrusion end 110 of the adjacent top warehouse plate 100. The lower plate 102 first fits with the edge of the upper plate 101 of the adjacent top warehouse plate 100, and then continues to extend upward to fill in the space between the upper plate 101 and the upper plate 101 of the adjacent top warehouse plate 100, forming a closed structure of the top warehouse plate 100 at the mating end 120. At the same time, it also makes the joint between the two top warehouse plates 100 smaller, preventing water from seeping into the battery swap station from the joint.

[0107] Specifically, Fig. 9 As shown, at the mating end 120, the third bend 122 of the mating portion 121 of the upper plate 101 extends along the second bend 113 of the raised portion 111 of the adjacent top panel 100, and the fourth bend 123 extends along the first bend 112 of the raised portion 111 of the adjacent top panel 100 to below the first bend 112. The connecting opening of the raised portion 111 and the mating portion 121 can be located at the bottom of one side, and the opening has a height difference with the joint of the two top panels 100, so that water cannot directly enter the joint of the two top panels 100 through the opening.

[0108] like Fig. 9 As shown, at the protruding end 110, the edge of the lower plate 102 is bent toward the upper plate 101, and the edge of the lower plate 102 extends toward the upper plate 101 at a right angle to the lower plate 102. The edge of the upper plate 101 is bent toward the lower plate 102, and the edge of the upper plate 101 extends toward the lower plate 102 at a right angle to the upper plate 101, so that the edge of the upper plate 101 is sleeved outside the edge of the lower plate 102 at this position. The inner surface of the edge of the upper plate 101 is attached to the outer surface of the edge of the lower plate 102, forming a staggered structure, and the inner cavity between the upper plate 101 and the lower plate 102 is sealed from the side.

[0109] At the mating end 120, the edge of the lower plate 102 is bent and extended toward the upper plate 101. After the edge of the lower plate 102 extends a distance toward the first plate at a right angle to the lower plate 102, it extends upward along the direction of the second bent portion 113 of the raised portion 111 of the adjacent top warehouse plate 100. The vertically extending portion of the edge of the lower plate 102 fits the edge of the upper plate 101 of the raised portion 111 of the adjacent top warehouse plate 100, and together with the edge of the lower plate 102 of the raised portion 111 of the adjacent top warehouse plate 100, the edge of the upper plate 101 of the raised portion 111 of the adjacent top warehouse plate 100 is sandwiched in the middle. The seam of the two top warehouse plates 100 is closed, filling the gap between the raised portion 111 and the mating portion 121.

[0110] At the same time, the portion of the edge of the lower panel 102 that extends upward along the direction of the second bend 113 of the raised portion 111 of the adjacent top panel 100 is sandwiched between the third bend 122 of the matching portion 121 and the second bend 113 of the raised portion 111 of the adjacent top panel 100, and the outer surface of the edge of the lower panel 102 is simultaneously attached to the outer surface of the edge of the upper panel 101 of the raised end 110 of the adjacent top panel 100. The gap between the upper panel 101 and the lower panel 102 at the matching end, as well as the gap between the third bend 122 of the matching portion 121 and the second bend 113 of the raised portion 111 of the adjacent top panel 100 are further filled. The top panel 100 is closed at the matching end 120, and the joint of the two top panels 100 is also made smaller, preventing water from seeping into the battery swap station from the joint.

[0111] like Fig. 9 As shown, the top of the raised portion 111 has a groove (not shown) extending along the extension direction of the top warehouse plate 100, and a first sealing strip 160 is installed in the groove. One side of the first sealing strip 160 is stuck inside the groove, and the other side is against the inner side of the top of the matching portion 121. The seal is arranged between the top of the raised portion 111 and the top of the matching portion 121. When rainwater accumulates on the top warehouse plate 100 assembly unit and causes water to rise from the gap between the raised portion 111 and the matching portion 121, it is blocked by the first sealing strip 160 arranged on the top and cannot penetrate into the battery swap station, thereby improving the waterproofness of the top warehouse plate 100 assembly unit.

[0112] In this embodiment, the first sealing strip 160 is a rubber strip. In other embodiments, the first sealing strip 160 can be set at the entrance of the fitting part of the raised portion 111 and the matching portion 121, or other waterproof materials can be selected. In this embodiment, the splicing direction of the top warehouse panel 100 is set to the first direction, that is, the top warehouse panel 100 is provided with a raised end 110 and a matching end 120 at two opposite ends along the first direction, and the raised end 110 and the matching end 120 are both protruded outward from the same side surface of the top warehouse panel 100 and extend in the same direction. A raised cavity is formed in the matching end 120, and the raised cavity in the matching end 120 is used to accommodate the raised end 110 of the adjacent top warehouse panel 100.

[0113] like Fig.10 As shown, the top warehouse panel 100 has side portions 130 at both ends of the second direction perpendicular to the first direction, and the side portions 130 are used to close the two ends of the top warehouse panel 100 along the first direction perpendicular to the first direction, that is, the upper plate 101, the lower plate 102 and the side portions 130 constitute a closed cavity. The portion of the side portion 130 located at the protruding end 110 is the first side panel 131, and the portion of the side portion 130 located at the mating end 120 is the second side panel 132. The second side portion 132 covers part of the outer side of the first side portion 131 of the adjacent top warehouse panel 100, splices and wraps the first side panel 131, so that the joints of the two are staggered, preventing rainwater from penetrating into the top warehouse panel 100 from the joints of the sides of the two adjacent top warehouse panels 100. The side portion of the top warehouse panel 100 extends downward in the vertical direction beyond the top of the side panel 20.

[0114] The raised end 110 and the mating end 120 are used to control rainwater from being discharged from the top plate 10 at both ends of the extension direction of the raised end 110 and the mating end 120, so as to prevent rainwater from penetrating into the interior of the top plate 100 from the connection between each top plate 100 in the top plate 10. The instantaneous rainfall needs to at least overflow the highest point of the raised end 110 or the mating end 120 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 110 and the mating end 120 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 top plate 10 is improved by the superimposed and mating structure of the raised end 110 and the mating end 120, so as to meet the strength requirements and waterproof requirements of the battery swap station. The side portion 130 covers the two side edges of the top plate 100, preventing liquid from penetrating into the top plate 100 from the side edges of the top plate 100, thereby preventing liquid from entering the interior of the battery swap station.

[0115] like Fig.12 and Fig.13As shown, the battery swap station includes a first wrap angle 170, which is respectively arranged at the protruding ends 110 and the mating ends 120 of the two outermost top panels 100 of the top plate 10, and the outer edge of the first wrap angle 170 extends vertically beyond the bottom edge of the protruding end 110 or the mating end 120. The edge of the first wrap angle 170 extends horizontally beyond the outer surface of the side panel 20. In this embodiment, the side edge of the top panel 100 is covered by the first wrap angle 170, and the side edge of the top panel 100 can be closed to prevent rainwater from penetrating from the side edge of the top panel 100 into the top panel 100 and then into the battery swap station, thereby improving the waterproofness of the battery swap station.

[0116] In this embodiment, the first wrap angle 170 includes a plurality of bends, which are interconnected and extend along the top surface of the raised end 110 or the mating end 120 of the top panel 100 to the outer edge of the top panel 10, and the first wrap angle 170 covers the outer edge of the raised end 110 or the mating end 120 of the top panel 100, and a groove is formed inside the first wrap angle 170. By providing the first wrap angle 170 on the edge of the top panel 100, the side edge of the top panel 100 is covered, and the side edge of the top panel 100 can be closed to prevent rainwater from penetrating from the side edge of the top panel 100 into the top panel 100 and then into the battery swap station, thereby improving the waterproofness of the battery swap station. Fig.12 As shown, the first corner wrap 170 also has a corner wrap side panel 171, which is fitted with the first side surface portion 131 of the protruding end 110 or the second side surface portion 132 of the mating end 120, further improving the water tightness of the top plate 10. The material of the first corner wrap 170 can refer to the material that can be selected for the upper plate 101 of the middle top warehouse plate 100, such as carbon fiber, polymer composite material or SMC resin material, which can not only meet the strength of the first corner wrap 170, but also reduce the weight of the first corner wrap 170 for easy installation.

[0117] Combine the following Figure 14-16 The structure of a side panel 200 used in the battery swap station in this embodiment is described in detail. Figure 14-16 As shown, in this embodiment, the side storage plate 200 is a rectangular plate structure, which has a first end and a second end opposite to each other and a third end and a fourth end arranged perpendicular to the extension direction of the first end and the second end. In this embodiment, the side storage plate 200 also includes a first layer plate and a second layer plate. For the convenience of distinction, according to the spatial position of the side storage plate 200, the first layer plate of the side storage plate 200 is called an outer layer plate 210, and the second layer plate is called an inner layer plate 220.

[0118] In this embodiment, a heat-insulating interlayer 230 is further provided between the outer plate 210 and the inner plate 220 of the side storage panel 200. The heat-insulating interlayer 230 has the function of heat insulation and heat preservation, and reduces heat transfer, so as to ensure the heat insulation and heat preservation requirements of the battery swap station, and also avoid the temperature in the battery swap station being too high or too low due to the external ambient temperature, which affects the charging and discharging performance of the battery and the service life of the equipment. In this embodiment, the materials used for the outer plate 210, the inner plate 220 and the heat-insulating interlayer 230 of the side storage panel 200 are the same as those used for the top storage panel 100 described above, and will not be repeated here. In other embodiments, the outer plate 210, the inner plate 220 and the heat-insulating interlayer 230 of the side storage panel 200 may also be other materials having the above-mentioned functions.

[0119] In this embodiment, the outer plate 210 and the inner plate 220 are also fixedly connected by a column. The connection method of the outer plate 210 and the inner plate 220 by the column is similar to the connection method of the upper plate 101 and the lower plate 102 in the top panel 100 mentioned above, and will not be repeated here. The side panel 200 is also installed on the frame of the battery swap station, such as the column 70 of the battery swap station, through the assembly parts 150 like the top panel 100 mentioned above, which facilitates the modular disassembly and assembly of the side panel 200 and the frame, further improving the overall strength of the battery swap station.

[0120] At the first end of the side panel 200, the outer panel 210 is provided with a first extension 211, and the first extension 211 extends beyond the edge of the inner panel 220. At the second end of the side panel 200, the inner panel 220 is provided with a second extension 221, and the second extension 221 extends beyond the edge of the outer panel 210, and the first extension 211 covers the second extension 221 of the adjacent side panel 200 in the longitudinal direction.

[0121] In this embodiment, the first extension portion 211 and the second extension portion 221 extend to the same length, so that the outer plate 210 and the inner plate 220 are symmetrical and have the same structure, which facilitates the production and replacement of the plates and improves the connection effect.

[0122] The side panel 200 adopts a multi-layer structure, and the outer panel 210 and the inner panel 220 are staggered at the connection through the extended first extension part 211 and the second extension part 221, which further enhances the water tightness of multiple panels when spliced, and prevents external liquid from directly penetrating into the battery swap station through the gaps at the connection of the panels.

[0123] like Figure 14-16As shown, in this embodiment, at the first end of the side panel 200, the edge of the inner panel 220 is bent and extended toward the outer panel 210 to form a second bent portion 222, and the first extension portion 211 abuts against the second bent portion 222. At the second end of the side panel 200, the edge of the outer panel 210 is bent and extended toward the inner panel 220 to form a first bent portion 212, and the second extension portion 221 abuts against the first bent portion 212. With the above structure, the first extension portion 211 of the outer panel 210 abuts against the second bent portion 222 of the inner panel 220, and the second extension portion 221 of the inner panel 220 abuts against the first bent portion 212 of the outer panel 210, so that the two opposite sides of the side panel 200 can be closed, so that the liquid cannot penetrate into the interior of the side panel 200 from these two sides, and will not damage the insulation layer or penetrate into the battery swap station through the panel.

[0124] In other embodiments, the bending portion may not be provided at the first end or the second end of the side storage plate 200 .

[0125] In other embodiments, the connection method of the extension portion and the bending portion is not limited thereto, as long as the connection portion can have a staggered structure.

[0126] In this embodiment, a seal (not shown) is provided between the first extension 211 of the side panel 200 and the second extension 221 of the adjacent side panel 200. A seal is provided between the first extension 211 of the side panel 200 and the second end of the adjacent side panel 200. A seal is provided between the first end of the side panel 200 and the adjacent second extension 221. By providing a seal at the connection, the connection of the side panel 200 can be multi-protected and watertightness can be improved.

[0127] In other embodiments, seals may not be provided at the connection between adjacent side storage panels 200 or seals may be provided at some positions. The setting position of the seals may be selected according to actual needs and is not limited here.

[0128] like Figure 14-16 As shown, in the present embodiment, at the third end and the fourth end of the side storage plate 200, the edge of the outer layer plate 210 of the side storage plate 200 is bent toward the direction of the inner layer plate 220 to form a third bending portion 213, and the edge of the inner layer plate 220 of the side storage plate 200 is bent toward the direction of the outer layer plate 210 to form a fourth bending portion 223, and the third bending portion 213 and the fourth bending portion 223 abut against each other to close the side storage plate 200 from the third end and the fourth end.

[0129] In this embodiment, a seal abutment portion (not shown) is provided on the outer surface of the third bent portion 213. The seal abutment portion is a groove provided on the connecting surface of the third bent portion 213 and the fourth bent portion 223. The seal abutment on the seal abutment portion can further enhance the waterproof effect of the third end and the fourth end of the side panel 200.

[0130] In this embodiment, the battery swap station further includes a second corner wrap, and the multiple side panels 200 spliced ​​in the transverse direction are connected to the frame of the battery swap station through the second corner wrap. The second corner wrap is used to connect two adjacent side panels 200 in the same plane. As mentioned above, the side panel 200 has a third end and a fourth end that are relatively arranged in the transverse direction, and the third end of the side panel 200 and the fourth end of the adjacent side panel 200 are clamped and fixed by the second corner wrap and the frame. By connecting the third end and the fourth end of the adjacent side panel 200 through the second corner wrap, the airtightness of the transverse connection of the side panel 200 can be increased, and the combined positioning of the side panel 200 can be facilitated.

[0131] The third bent portion 213 and the fourth bent portion 223 of the third end of the side panel 200 abut against one side of the second wrap angle, and the third bent portion 213 and the fourth bent portion 223 of the fourth end of the adjacent side panel 200 abut against the other side of the second wrap angle. By bending and abutting the third and fourth ends of the side panel 200, the third and fourth ends of the side panel 200 can form a closed structure to prevent liquid from entering the side panel 200 from these two ends of the side panel 200, further improving the waterproof effect. At the same time, the third bent portion 213 and the fourth bent portion 223 abut against the second wrap angle, which can prevent liquid from penetrating from the connection position between the side panel 200 and the second wrap angle, thereby improving the waterproofness and connection strength of the side panel 20.

[0132] Figure 17-19 Schematic diagram of a second wrap angle 300 according to an embodiment of the present invention.

[0133] The second corner wrap 300 includes a cover plate 310 and a connection plate 320. One end of the connection plate 320 is connected to the inner surface of the cover plate 310. The connection plate 320 is provided with a connector 330. The connector 330 is used to connect and fix the second corner wrap 300 to the frame of the battery swap station. The edge of the cover plate 310 exceeds the edge of the connection plate 320. The portion of the cover plate 310 that exceeds the edge of the connection plate 320 is used to cover the third end of the side warehouse panel 200 and the fourth end of the adjacent side warehouse panel 200. The cover plate 310 and the connection plate 320 form a roughly T-shaped structure, which can facilitate the connection of two parallel side warehouse panels 200. At the same time, the connector 330 is provided on the connection plate 320 to connect the frame, which is conducive to connecting the battery swap station as a whole. At the same time, the cover plate 310 covers the side warehouse panel 200 to ensure the airtightness between the second corner wrap 300 and the side warehouse panel 200, and improve the connection strength between the warehouse panels.

[0134] The connecting member 330 is disposed on the outer surface of the connecting plate 320 away from the covering plate 310. The connecting plate 320 has a side surface adjacent to the inner surface of the covering plate 310, and the connecting member 330 extends and protrudes from the side surface of the connecting plate 320 in a direction away from the side surface. In other embodiments, the connecting plate 320 has an end surface away from the other end of the covering plate 310, and the connecting member 330 extends and protrudes from the end surface of the connecting plate 320 in a direction away from the end surface. The connecting member 330 is configured in the above-mentioned form to facilitate the assembly and connection between the second corner wrap 300 and the frame.

[0135] In this embodiment, the connector 330 is a buckle, which extends outward from the outer surface of the connector plate 320. In other embodiments, the connector 330 may also be a slot, which is recessed inward from the outer surface of the connector plate 320. The slot may be provided on the end surface of the connector plate 320 away from the other end of the cover plate 310, or on the side surface adjacent to the inner surface of the cover plate 310. The connector 330 is provided as a buckle or a slot, which can realize a snap connection, and facilitates modular assembly of the side storage panel 200.

[0136] The connecting member 330 includes a first guide surface 340 and a first engaging surface 350. The first guide surface 340 is used to guide the engaging matching portion 701 of the column 70 into the first engaging groove 360 ​​between the first engaging surface 350 and the inner surface of the cover plate 310. The first engaging surface 350 is used to abut against the engaging matching portion 701 to connect and fix the second wrap angle 300. The first guide surface 340 is inclined toward the first engaging groove 360.

[0137] The first guide surface 340 is provided to guide the snap-fitting portion 701 into the first snap-fitting groove 360 ​​, so that the connector 330 and the snap-fitting portion 701 are easier to assemble. The first guide surface 340 is provided to be inclined toward the first snap-fitting groove 360 ​​, so that the snap-fitting portion 701 can be more easily snapped into the first snap-fitting groove 360 ​​.

[0138] In this embodiment, taking the assembly of the second corner wrap 300 and the column 70 as an example, the connecting member 330 is engaged with the snap-fit ​​matching portion 701 of the column 70 to assemble the second corner wrap 300 and the column 70 .

[0139] In this embodiment, the snap-fit ​​matching portion 701 is an L-shaped structure, but the present invention is not limited thereto, and the snap-fit ​​matching portion 701 may also be formed as a strip-shaped protrusion on the surface of the column 70. When the second corner 300 is assembled with other components on the frame, it is snapped with the corresponding snap-fit ​​matching portion 701 on the other components. A first groove 370 is provided on the inner surface of the cover plate 310, and a sealing member is provided in the first groove 370. By providing a sealing member on the inner surface of the cover plate 310, rainwater is prevented from penetrating from the contact surface between the cover plate 310 and the side panel 200, thereby improving the waterproof performance.

[0140] In other embodiments, a groove may be provided on the opposite outer surface of the connecting plate 320, and a sealing member may be provided in the groove. By providing a groove for preventing the sealing member from being provided on the opposite outer surface of the connecting plate 320, rainwater is prevented from penetrating from the contact surface between the connecting plate 320 and the side storehouse plate 200, thereby improving the waterproof performance.

[0141] The first groove 370 extends along the length direction of the second corner 300 to improve the waterproof performance between the entire second corner 300 and the side panel 200. The material of the second corner 300 is aluminum alloy or plastic. Aluminum alloy and plastic are cheap and high in strength, which can improve strength and reduce production costs.

[0142] In other embodiments, the cover plate 310 may also include an inner wall and an outer wall, a hollow cavity is formed between the outer wall and the inner wall, the edge of the outer wall exceeds the edge of the inner wall, and the clamping plate is connected to the inner wall. A thermal insulation layer may be provided in the hollow cavity as required, and the thermal insulation layer is made of aerogel, rock wool or polyurethane foam material, etc., to improve the thermal insulation performance of the second corner 300. The edge of the outer wall exceeds the edge of the inner wall, thereby preventing water from penetrating from both sides of the outer wall of the second corner to a certain extent, achieving the effect of waterproofing and thermal insulation. The connecting plate 320 is connected to the inner wall.

[0143] In this embodiment, the battery swap station further includes a third wrap angle, which is used to connect the third end and the fourth end of two adjacent side panels 200 that form an angle. The third wrap angle is provided to increase the tightness of the connection at the corner of the battery swap station and facilitate the assembly and positioning of the side panels 200.

[0144] Figure 20-22 It is a structure of a third corner wrap 400 according to an embodiment of the present invention. The third corner wrap 400 includes an inner wall 410 and an outer wall 420, and a hollow cavity 430 is formed between the outer wall 420 and the inner wall 410, and the edge of the outer wall 420 exceeds the edge of the inner wall 410. Insulating materials can be arranged in the hollow cavity 430 of the third corner wrap 400 as needed, and the edge of the outer wall 420 of the third corner wrap 400 exceeds the edge of the inner wall 410, thereby preventing water from penetrating from both sides of the outer wall 420 of the third corner wrap 400 to a certain extent, achieving the effect of waterproofing and heat preservation. The inner surface 411 of the inner wall 410 facing away from the hollow cavity 430 is provided with a snap-fitting part 440. It is connected to the column 70 or frame of the battery swap station through the snap-fitting part 440, so as to facilitate the side warehouse plate 200 to be clamped and fixed between the third corner wrap 400 and the column 70. The engaging member 440 is a buckle, and the buckle is extended from the inner surface 411 to a direction away from the inner surface 411 .

[0145] In other embodiments, the engaging member 440 may also be a slot, which is recessed from the inner surface 411 toward the direction close to the hollow cavity 430. The engaging member 440 is configured as a buckle or a slot to facilitate connection to the column 70 or frame of the battery swap station.

[0146] The buckle includes a second connecting portion 441 and a second clamping portion 442. The second clamping portion 442 is connected to the inner wall 410 through the second connecting portion 441. The second clamping portion 442 has a protrusion extending outward from the second connecting portion 441. The outward extension here, such as Figure 21-22 As shown, it refers to extending toward the edge of the inner wall 410 or the outer wall 420 on the cross section of the third wrap angle 400. The second clamping portion 442 is arranged in such a structure to facilitate connection with the column 70 or frame of the battery swap station.

[0147] like Figure 21-22 As shown, the second clamping portion 442 also includes a second guide surface 443 and a second clamping surface 444. The second guide surface 443 is used to guide the clamping matching portion 701 of the column 70 into the second clamping groove (not shown in the figure) between the second clamping portion 442 and the inner surface 411. The second clamping surface 444 is used to abut against the clamping matching portion 701 to connect and fix the third wrap angle 400. The second guide surface 443 and the clamping surface are respectively arranged on opposite sides of the second clamping portion 442, and the second guide surface 443 is inclined toward the second clamping groove. By providing the second guide surface 443 so as to guide the clamping matching portion 701 into the second clamping groove, the clamping member 440 and the clamping matching portion 701 are easier to assemble. By setting the second guide surface 443 to be inclined toward the second clamping groove, the clamping matching portion 701 can be more easily clamped into the second clamping groove.

[0148] In this embodiment, taking the assembly of the third wrap angle 400 and the column 70 as an example, the engaging member 440 is engaged with the engaging matching portion 701 of the column 70 to assemble the third wrap angle 400 and the column 70 .

[0149] In this embodiment, the engaging and matching portion 701 is an L-shaped structure, but the present invention is not limited thereto. The engaging and matching portion 701 may also be a strip-shaped protrusion formed on the surface of the pillar 70 .

[0150] When the third wrap angle 400 is assembled with other components on the frame, it is engaged with corresponding engaging matching pieces on the other components.

[0151] like Figure 21-22As shown, the inner wall 410 includes at least two inner flat plate portions 412 and an inner bending portion 413, and the inner bending portion 413 is connected between two adjacent inner flat plate portions 412; the outer wall 420 includes at least two outer flat plate portions 421 and an outer bending portion 422, and the outer bending portion 422 is connected between two adjacent outer flat plate portions 421. The outer flat plate portion 421 and the outer bending portion 422 correspond to the positions of the inner flat plate portion 412 and the inner bending portion 413. The bending portion can be quasi-arc-shaped or quasi-right-angled. By setting the bending portion and the flat plate portion, the third wrap angle 400 forms an angle to facilitate the connection of the two side warehouse panels 200 at a predetermined angle.

[0152] The engaging member 440 is disposed on the inner flat plate portion 412. By disposing the engaging member 440 on the inner flat plate portion 412, it is convenient to connect with other components.

[0153] In other embodiments, the engaging member 440 may also be disposed on the inner bending portion 413.

[0154] The inner wall 410 has connecting walls 450 bent toward the outer wall 420 at both ends, and the inner wall 410 is connected to the outer wall 420 via the connecting walls 450. The third wrap angle 400 forms an annularly closed hollow cavity 430 by providing the connecting walls 450.

[0155] The portion of the outer wall 420 that exceeds the inner wall 410 is an extension portion 4201, and the inner surface of the extension portion 4201 is in contact with the outer surface of the side panel 200. The arrangement of the outer wall 420 exceeding the inner wall 410 prevents external liquid from penetrating into the third corner 400 to a certain extent.

[0156] The end surface of the side storage panel 200 abuts against the connecting wall 450 , and the inner surface of the extending portion 4201 is in contact with the outer surface of the side storage panel 200 .

[0157] By abutting the end surface of the side panel 200 against the second connection portion 441 and the outer surface of the side panel 200 against the extension portion 4201 , liquid outside the battery swap station is further prevented from penetrating into the third corner 400 .

[0158] In this embodiment, the inner surface of the extension portion 4201, i.e., the surface facing the locking member 440, may be provided with a second groove 460 for installing a sealing strip extending along the length direction of the third corner 400 to further improve the waterproof performance of the third corner 400.

[0159] The material of the third corner wrap 400 is aluminum alloy or plastic. A heat-insulating layer may be provided in the hollow cavity 430; the heat-insulating layer is made of aerogel, rock wool or polyurethane foam material. Aluminum alloy and plastic are cheap and high in strength, which can improve strength and reduce production costs; by providing a heat-insulating layer in the hollow cavity 430, the heat-insulating performance of the third corner wrap 400 can be improved.

[0160] like Figure 1 As shown, a door 50 for personnel and equipment to enter and exit is opened on the wall of the charging room 30 of the battery swap station, and at least one side of the door frame 510 of the door 50 abuts against the side panel 200. The location and structure of the door 50 are shown in FIG. Figure 23-33 shown.

[0161] In this embodiment, the door frame 510 has two opposite and vertically arranged side portions 513, a lower portion 516 located at the bottom and connected to the lower ends of the two side portions 513, and an upper portion 530 located at the top and connected to the upper ends of the two side portions 513. The two side portions 513 and the upper portion 530 of the door frame 510 are both connected to the side storage plate 200.

[0162] In this embodiment, the upper end of the door frame 510 has a door lintel 530, which is an upper edge portion 530 disposed at the top of the door frame 510. In other embodiments, the door lintel 530 may also be a separate component disposed above the upper edge portion 530 of the top of the door frame 510.

[0163] A foot 80 is also provided below the door frame 510, and the bottom of the lower edge 516 of the door frame 510 is connected and fixed to the foot 80. By providing the foot 80 below the door frame 510, it is avoided that the door frame 510 is directly installed on the ground so that the bottom height of the door frame 510 is insufficient, resulting in excessive rain overflowing the door frame 510 and entering the interior of the battery swap station.

[0164] In other embodiments, the side edges 513 of the door frame 510 and the side storage panels 200 may also be connected and fixed via other components (eg, cross beams 60 , columns 70 , etc.).

[0165] The first extension 211 of the side panel 200 abuts against the upper edge 530 of the door frame 510. The upper edge 530 of the door frame 510 forms a part of the door lintel 530, and the side of the upper edge 530 of the door frame 510 abutting against the side panel 200 is stepped, that is, the first extension 211 abuts against the stepped portion of the door lintel 530.

[0166] The side panel 200 and the door lintel 530 are installed in the above-mentioned structural form, which can prevent rainwater from flowing along the side panel 200 to the gap at the connection between the side panel 200 and the door lintel 530 and entering the battery swap station, affecting the normal operation of the battery swap equipment and charging equipment in the battery swap station.

[0167] In this embodiment, a seal (not shown in the figure) is provided between the first extension portion 211 and the step portion, and the seal is provided on the inner surface of the first extension portion 211. The seal is provided to further enhance the sealing effect between the side storage plate 200 and the door lintel 530, thereby preventing rainwater from flowing along the side storage plate 200 to the gap at the connection between the side storage plate 200 and the door lintel 530 and entering the battery swap station.

[0168] In other embodiments, the sealing member may also be provided on the surface of the step portion opposite to the first protruding portion 211. Alternatively, the surface of the step portion opposite to the first protruding portion 211 is provided with a sealing member.

[0169] The frame includes columns 70 and crossbeams 60. The crossbeams 60 are connected to the door lintel 530 and the side storage panels 200, respectively, to enhance the connection strength between the side storage panels 200 and the door lintel 530 and the frame.

[0170] like Fig.28 As shown, a second sealing strip 550 is also provided at the connection between the crossbeam 60 , the door lintel 530 and the side storage panel 200 to further enhance the sealing effect between the side storage panel 200 and the door lintel 530 .

[0171] The side panel 200 has a third end and a fourth end opposite to each other in the transverse direction, and the side edge 513 of the door frame 510 is connected to the third end or the fourth end of the side panel 200. The connection strength between the side panel 200 and the door frame 510 is enhanced.

[0172] Combine the following Figure 23-33 One implementation of the door 50 provided on the battery swap station in this embodiment is described in detail.

[0173] like Figure 23-33 As shown, a door 50 for a battery swap station of the present embodiment includes a door panel 520 and a door frame 510. The door panel 520 is located inside the door frame 510. The upper end of the door frame 510 has a lintel 530. A waterproof eave 540 is provided on the outer surface of the lintel 530. The inner surface of the lintel 530 extends downward beyond the top of the door panel 520. The waterproof eave 540 extends outward from the lintel 530 beyond the outer side surface of the door panel 520.

[0174] In this embodiment, the door lintel 530 is an upper edge portion 530 disposed at the top of the door frame 510. In other embodiments, the door lintel 530 may also be a separate component disposed above the upper edge portion 530 at the top of the door frame 510.

[0175] The door 50 of this embodiment is provided with a waterproof eaves 540 on the lintel 530, which can prevent rainwater from sliding along the outer surface of the side panel 200 of the battery swap station into the gap between the door frame 510 and the door, thereby preventing rainwater from entering the battery swap station. By extending the inner surface of the lintel 530 downward beyond the top of the door panel 520, it can effectively prevent small particles such as sand and dust from the outside from entering the battery swap station through the gap between the lintel 530 and the door panel 520 and affecting the normal operation of the internal equipment.

[0176] The waterproof eaves 540 extend horizontally beyond the outer side of the door panel 520. The outer end of the waterproof eaves 540 extends obliquely downward and exceeds the top of the door panel 520 in the vertical direction. Fig.28As shown, in this embodiment, the waterproof eaves 540 is a plate arranged obliquely downward, and the door lintel 530 is made of a hollow square tube structure. The outer side surfaces of the waterproof eaves 540 and the door lintel 530 form an L-shaped structure.

[0177] In this embodiment, by extending the waterproof eaves 540 horizontally outward beyond the door panel 520 and slanting downward so that the outer end of the waterproof eaves 540 extends downward beyond the top of the door panel 520, rain water sliding down from above the door frame 510 can be prevented from dripping directly from the door frame 510. The rain water is dripped at a distance from the door, which prevents muddy water brought up by rain water from splashing onto the door, causing mud and other materials to adhere to the door panel 520 and the door frame 510, thereby affecting the appearance.

[0178] In other embodiments, the upper end surface of the waterproof eaves 540 may also be an arc-shaped structure or other structure that is conducive to drainage.

[0179] The inner surface of the door lintel 530 extends downward to form a stopper, which abuts against the surface of the door panel 520. Fig.28 As shown, the inner side surface of the upper side portion 530 (door lintel 530 ) of the door frame 510 has an upper side stopper 531 , and the upper side stopper 531 extends downward beyond the lower end surface of the upper side portion 530 .

[0180] The upper stopper 531 can limit the opening direction of the door panel 520 on the one hand, and form a sealing surface with the closed door panel 520 on the other hand to prevent external wind or rain from entering the battery swap station along the gap between the door frame 510 and the door panel 520.

[0181] In this embodiment, a sealing strip (not shown in the figure) is provided on the surface where the upper stopper 531 contacts the door panel 520. The sealing strip is provided on the upper stopper 531 to enhance the sealing effect between the upper end of the door panel 520 and the door lintel 530, further ensuring the sealing between the inside and outside of the battery swap station after the door panel 520 is closed, so that a stable working environment is maintained inside the battery swap station.

[0182] In other embodiments, the sealing strip may also be provided on the surface where the door panel 520 abuts against the upper stopper 531. Alternatively, the sealing strip may be provided on both the door panel 520 and the upper stopper 531.

[0183] like Fig.28As shown, the upper stopper 531 is provided with a mounting groove 532, and the mounting groove 532 is provided on a side surface of the upper stopper 531 abutting against the door panel 520. In this embodiment, the mounting groove 532 is used to install a sealing strip. Of course, in other embodiments, the mounting groove 532 can also be used to install a buffering member (such as an elastic sealing body, a spring, etc.), and the buffering of the buffering member is used to prevent the door panel 520 from impacting the door lintel 530 when closing. The cross-sectional shape of the mounting groove 532 can be various, such as L-shaped, trapezoidal, T-shaped, etc.

[0184] By providing a mounting groove 532 on a side of the upper stopper 531 opposite to the door panel 520 , it is convenient to mount the buffer component or the sealing component, so that the buffer component or the sealing component is not easy to fall off.

[0185] In this embodiment, a sealing member (not shown in the figure) is provided between the door lintel 530 and the door panel 520. The sealing member is provided on the surface of the door lintel 530 facing the door panel 520.

[0186] By providing a seal between the door lintel 530 and the door panel 520, the sealing effect between the door lintel 530 and the door panel 520 is enhanced, and the sealing between the inside and the outside of the battery swap station is further ensured after the door is closed, so that a stable working environment is maintained inside the battery swap station.

[0187] In other embodiments, the sealing member disposed between the door lintel 530 and the door panel 520 may also be disposed on the surface of the door panel 520 facing the door lintel 530. Alternatively, sealing members are disposed on the surfaces of the door lintel 530 and the door panel 520 facing each other.

[0188] The outer surface of the door lintel 530 is provided with a step portion, which is used to abut against the side panel 200 of the battery swap station. The door lintel 530 and the side panel 200 abut against each other through the step-shaped structure to form a sealing structure, which effectively enhances the sealing of the connection between the door lintel 530 and the side panel 200.

[0189] In this embodiment, if Fig.28 and Fig.31 As shown, a step portion is provided on the upper surface of the door lintel 530, and the first extension portion 211 of the outer layer plate 210 of the side storage plate 200 abuts against the upper surface and side surfaces of the step portion.

[0190] In other embodiments, the door lintel 530 is a square tube structure, that is, the outer surface of the door lintel 530 is a plane, and the side storage plate 200 abuts against the plane. The door lintel 530 can also be other special-shaped structures, which will not be described in detail here.

[0191] The door frame 510 includes two oppositely arranged side portions 513, the two ends of the door lintel 530 are respectively connected to the two side portions 513, and the door panel 520 is hinged to one of the side portions 513. The side portion 513 includes a third connecting portion 511 and a covering portion 512, the third connecting portion 511 is used to connect to the crossbeam 60 and / or the column 70 of the battery swap station, and the covering portion 512 is used to cover the outer side of the side panel 200 of the battery swap station.

[0192] In this embodiment, if Fig.30 , Fig.32 and Fig.33 As shown, a hinge shaft 515 is provided on one of the side portions 513 of the door frame 510, and the door panel 520 is installed on the door frame 510 through the hinge shaft 515. The third connecting portion 511 of the side portion 513 is fixed to the crossbeam 60 and the column 70 of the frame of the battery swap station. A clamping piece (not shown in the figure) is provided at the end of the third connecting portion 511, and the clamping piece is used to clamp and fix the side portion 513 of the door frame 510 on the crossbeam 60 and the column 70, thereby enhancing the connection strength between the door frame 510 and the side panel 200. The covering portion 512 of the side portion 513 is coated on the outer surface of the side panel 200, so that the side portion 513 of the door frame 510 and the side panel 200 have better sealing performance, thereby preventing rainwater from penetrating into the side panel 200 from the connection between the two.

[0193] In other embodiments, the third connection portion 511 may also be connected to the beam 60 or the column 70 of the battery swap station.

[0194] like Fig.26 , Fig.28 and Fig.31 As shown, side stoppers 514 are also provided on the two opposite side portions 513, and the side stoppers 514 extend from the inner surface of the side portions 513 to the left and right sides respectively. The side stoppers 514 and the upper stoppers 531 together limit the opening direction of the door panel 520, and can form a sealing surface with the two sides of the closed door panel 520, thereby preventing the outside wind or rain from entering the battery swap station along the gap between the door frame 510 and the door panel 520.

[0195] In this embodiment, a sealing strip (not shown) is also provided on the surface where the side stopper 514 contacts the door panel 520. By providing the sealing strip on the side stopper 514, the sealing effect between the two side ends of the door panel 520 and the two side edges 513 of the door frame 510 is enhanced, and the sealing between the inside and the outside of the battery swap station is further ensured after the door panel 520 is closed, so that a stable working environment is maintained inside the battery swap station.

[0196] In other embodiments, the sealing strip may also be provided on the surface where the door panel 520 abuts against the side stopper 514. Alternatively, sealing strips are provided on the surfaces where the side stopper 514 and the door panel 520 abut against each other.

[0197] In this embodiment, the side stopper 514 is also provided with a mounting groove (not shown in the figure), which is provided on a side surface of the side stopper 514 abutting against the door panel 520. In this embodiment, the mounting groove is used to install a sealing strip. Of course, in other embodiments, the mounting groove can also be used to install a buffering member (such as an elastic sealing body, a spring, etc.), and the buffering of the buffering member is used to prevent the door panel 520 from impacting the side stopper 514 when closing.

[0198] like Fig.33 As shown, a second sealing strip 550 is provided between the covering portion 512 and the outer side of the side panel 200. By providing a sealing strip between the covering portion 512 and the outer side of the side panel 200, the sealing performance of the side edge portion 513 of the door frame 510 and the side panel 200 is further enhanced. The bottom of the door frame 510 includes a lower edge portion 516, which is mounted on the crossbeam 60 and / or the column 70 of the battery swap station. The lower edge portion 516 has an extension portion 518, which extends downward from the surface of the lower edge portion 516 and exceeds the top of the foot 80 of the battery swap station.

[0199] In this embodiment, if Figure 23-27 and Fig.29 As shown, both ends of the lower edge 516 of the door frame 510 are fixed on the column 70, the bottom surface of the lower edge 516 is connected to the foot 80 of the battery swap station, and the outer side surface of the lower edge 516 has an extension 518 extending downward, and the extension 518 is coated on the outer side surface of the foot 80. By providing the extension 518 that can be coated on the outer side of the foot 80 on the lower edge 516 of the door frame 510, rainwater is prevented from penetrating into the side panel 200 from the connection between the lower edge 516 of the door frame 510 and the foot 80 of the battery swap station.

[0200] like Fig.29 As shown, a second sealing strip 550 is provided between the extension portion 518 and the foot 80, and the second sealing strip 550 is provided on the surface opposite to the extension portion 518 and the foot 80. By providing a sealing strip between the extension portion 518 and the foot 80, it is prevented that when the rainwater is too heavy and overflows the height of the foot 80, the water will not penetrate into the side storage plate 200 from the gap at the connection between the lower edge portion 516 of the door frame 510 and the foot 80.

[0201] In other embodiments, the sealing strip is disposed on the surface of the foot 80 opposite to the extension 518. Alternatively, the extension 518 and the foot 80 are both provided with sealing strips. Alternatively, a sealing strip is also provided between the bottom surface of the lower edge 516 and the top of the foot 80.

[0202] In such Fig.29 As shown, the edge of the extension portion 518 is bent toward the foot 80 and abuts against the outer side of the foot 80. The extension portion 518 adopts this structural form to enhance the sealing and anti-seepage effect.

[0203] like Fig.26 , Fig.29 and Fig.33 As shown, a lower stopper 517 is also provided on the lower edge portion 516, and the lower stopper 517 is formed by extending upward from the inner surface of the lower edge portion 516. The lower stopper 517, the upper stopper 531, and the side stopper 514 together limit the opening direction of the door panel 520, and can form a sealing surface with the lower end of the closed door panel 520, further preventing the outside wind or rain from entering the battery swap station along the gap between the door frame 510 and the door panel 520.

[0204] In this embodiment, a sealing strip (not shown in the figure) is also provided on the surface where the lower stopper 517 contacts the door panel 520. The sealing strip is provided on the lower stopper 517 to enhance the sealing effect between the lower end of the door panel 520 and the lower edge 516 of the door frame 510, further ensuring the sealing between the inside and outside of the battery swap station after the door panel 520 is closed, so that a stable working environment is maintained inside the battery swap station.

[0205] In other embodiments, the sealing strip may also be provided on the surface where the door panel 520 abuts against the side stopper 514. Alternatively, the sealing strip is provided on the surface where the door panel 520 abuts against the lower stopper 517.

[0206] In this embodiment, the lower stopper 517 is also provided with a mounting groove (not shown in the figure), which is provided on the side surface of the lower stopper 517 abutting against the door panel 520. In this embodiment, the mounting groove is used to install a sealing strip. Of course, in other embodiments, the mounting groove can also be used to install a buffering member (such as an elastic sealing body, a spring, etc.), and the buffering of the buffering member is used to prevent the door panel 520 from impacting the lower stopper 517 when closing.

[0207] In this embodiment, the door panel 520 also includes a first layer and a second layer, and a plurality of columns are also provided between the first layer and the second layer, and the first layer and the second layer are fixedly connected by the columns. A heat preservation layer is also provided between the first layer and the second layer.

[0208] In other embodiments, the door panel 520 may also be a multi-layer structure or a single-layer structure.
