[0057] The present invention will be further described below with reference to the accompanying drawings by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0058] Example 1

[0059] Figure 1 An embodiment according to the present invention schematically shows a battery swapping station 100.

[0060] The battery swapping station 100 includes a battery swapping platform 101, two charging rooms 102 respectively disposed on both sides of the battery swapping platform 101, and a battery swapping cart that shuttles between the battery swapping platform 101 and the charging rooms 102 and is used for disassembling and installing the vehicle's battery pack. The battery swapping station 100 may further include a monitoring room, a storage room, etc.

[0061] The battery swapping platform 101 is used to carry the vehicle with the battery pack to be replaced. The vehicle drives into and docks on the battery swapping platform 101. The battery swapping cart disassembles the old battery pack to be charged on the vehicle and installs a fully charged new battery pack. After disassembling the old battery on the vehicle, the battery swapping cart transports it to the charging room 102 for charging.

[0062] Equipment such as charging racks, elevators, and main control boxes are placed in the charging room 102. The charging racks are used to accommodate the battery packs and charge the old battery packs. The elevators are used to exchange the battery packs with the battery swapping cart and take out or put the battery packs into the charging racks.

[0063] AsFigure 2 As shown, the battery swapping station 100 of this embodiment is supported by multiple frames 105 and is divided into multiple functional rooms such as a charging room 102, a monitoring room, etc., and its outer surface is covered with storage panels 112 to isolate the inside and outside of the functional rooms, preventing external impurities such as rainwater and dust from entering the inside of the battery swapping station 100 and damaging the electrical components inside the battery swapping station 100, such as charging racks and main control boxes.

[0064] The battery swapping station 100 has a top surface 103, side surfaces 104, and a bottom surface. Both the top surface 103 and the side surfaces 104 of the battery swapping station 100 are covered with a storage panel combination unit 111. The storage panel combination unit 111 is connected to the frame 105 of the battery swapping station 100 by means such as snap-fitting.

[0065] The storage panel combination unit 111 is detachably installed around the frame 105

[0066] As Figure 3 shown, the frame 105 includes multiple cross beams 107 and columns 108 that are combined with each other.

[0067] The storage panel combination unit 111 can be connected to the cross beams 107 and columns 108 of the frame 105 through the storage panels 112. For example, snap fasteners are provided on the storage panels 112, and corresponding slots are provided on the frame 105, and the two are assembled together through the snap-fitting of the snap fasteners and the slots.

[0068] The storage panel combination unit 111 can also be connected to the cross beams 107 and columns 108 of the frame 105 through the corner angles 141. For example, the connecting members on the corner angles 141 are snap-fitted with the snap-fitting members on the columns 108 or cross beams 107, and the two are assembled together.

[0069] The storage panel combination unit 111 includes storage panels 112 and corner angles 141. The corner angles 141 are used for connecting adjacent storage panels 112 in the battery swapping station 100 or energy storage station.

[0070] The storage panel 112 is clamped and fixed between the covering plate 142 of the corner angle 141 and the frame 105.

[0071] Figures 6 - 8 Embodiment 1 according to the present invention illustrates a corner angle 141.

[0072] The corner angle 141 includes: a covering plate 142 and a connecting plate 143. One end of the connecting plate 143 is connected to the inner surface of the covering plate 142. Connecting members 145 are provided on the connecting plate 143. The connecting members 145 are used for connecting and fixing the corner angle 141 to the frame 105 of the battery swapping station 100 or energy storage station. The edge of the covering plate 142 extends beyond the edge of the connecting plate 143. The part of the covering plate 142 that extends beyond the edge of the connecting plate 143 is used for covering the storage panel 112.

[0073] The corner wrap 141 includes a covering plate 142 and a connecting plate 143 which are connected to each other, forming a substantially T-shaped structure, which can facilitate the connection of two parallel storage panels 112. At the same time, a connecting member 145 is provided on the connecting plate 143 to connect to the frame 105, which is beneficial to connecting the swapping station 100 or the energy storage station into a whole. At the same time, the covering plate 142 covering the storage panel 112 ensures the liquid tightness between the corner wrap 141 and the storage panel 112.

[0074] The connecting member 145 is arranged on the outer surface of the connecting plate 143 away from the covering plate 142.

[0075] In other embodiments, the connecting plate 143 has a side surface adjacent to the inner surface of the covering plate 142, and the connecting member 145 extends and protrudes from the side surface of the connecting plate 143 in a direction away from the side surface.

[0076] In other embodiments, the connecting plate 143 has an end surface at the other end away from the covering plate 142, and the connecting member 145 extends and protrudes from the end surface of the connecting plate 143 in a direction away from the end surface.

[0077] The connecting member 145 is arranged in the above form, which is convenient for the assembly and connection between the corner wrap 141 and the frame 105.

[0078] The connecting member 145 is a buckle, and the buckle extends and protrudes outward from the outer surface of the connecting plate 143.

[0079] Optionally, the connecting member 145 can also be a clamping groove, which is recessed inward from the outer surface of the connecting plate 143. The clamping groove can be arranged at the end surface of the connecting plate 143 at the other end away from the covering plate 142, or can be the side surface adjacent to the inner surface of the covering plate 142.

[0080] The connecting member 145 is arranged as a buckle or a clamping groove, which can achieve snap connection and is convenient for modular assembly of the storage panel 112.

[0081] The connecting member 145 includes a guiding surface 146 and a clamping surface 147. The guiding surface 146 is used to guide a clamping matching member into a clamping groove 148 between the clamping surface 147 and the inner surface of the covering plate 142. The clamping surface 147 is used to abut against the clamping matching member to connect and fix the corner wrap 141. The guiding surface 146 and the clamping surface 147 are respectively arranged on opposite sides of the connecting plate 143. Preferably, the guiding surface 146 is inclined towards the clamping groove 148.

[0082] By providing the guiding surface 146 to guide the clamping matching member into the clamping groove 148, it makes the connection member part and the clamping matching member easier to assemble. Setting the guiding surface 146 to be inclined towards the clamping groove 148 can make it easier to snap the clamping matching member into the clamping groove.

[0083] In this embodiment, taking the assembly of the corner guard 141 and the column 108 as an example, the connecting member engages with the engaging and matching member of the column 108 so that the corner guard 141 and the column 108 are assembled.

[0084] In this embodiment, the engaging and matching member is an L-shaped member, but the present invention is not limited thereto, and the engaging and matching member may also be a strip-shaped protrusion formed on the surface of the column 108.

[0085] When the corner guard 141 is assembled with other components on the frame 105, it is snap-connected to the corresponding engaging and matching members on the other components.

[0086] A groove 150 is provided on the inner surface of the cover plate 142, and a sealing member is arranged in the groove 150.

[0087] By arranging a sealing member on the inner surface of the cover plate 142, rainwater is prevented from seeping in from the contact surface between the cover plate 142 and the storage board 112, improving the waterproof performance.

[0088] In other embodiments, grooves 150 may also be provided on the opposite outer surfaces of the connecting plate 143, and sealing members are arranged in the grooves 150.

[0089] By arranging grooves 150 for preventing sealing members on the opposite outer surfaces of the connecting plate 143, rainwater is prevented from seeping in from the contact surface between the connecting plate 143 and the storage board 112, improving the waterproof performance.

[0090] The groove 150 extends along the length direction of the corner guard 141 so as to improve the waterproof performance between the entire corner guard 141 and the storage board 112.

[0091] The material of the corner guard 141 is aluminum alloy or plastic. Aluminum alloy and plastic are inexpensive and have high strength, which can improve the strength and reduce the production cost.

[0092] In other embodiments, the cover plate 142 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 extends beyond the edge of the inner wall, and the connecting plate 143 is connected to the inner wall.

[0093] Heat insulation materials can be arranged in the hollow cavity of the corner guard 141 as needed. The edge of the outer wall of the corner guard 141 extends beyond the edge of the inner wall, so as to prevent water from seeping in from both sides of the outer wall of the corner guard 141 to a certain extent, achieving the effect of both waterproofing and heat insulation.

[0094] A heat insulation layer can be arranged in the hollow cavity; the heat insulation layer is made of aerogel, rock wool or polyurethane foam material, etc. By arranging a heat insulation layer in the hollow cavity, the heat insulation performance of the corner guard 141 can be improved. (Specifically, reference can be made to Embodiment 2)

[0095] The corner piece 141 is used to connect two adjacent library plates 112 in the same plane. The inner surface of the covering plate 142 abuts against the outer surface of the library plate 112. The connecting plate 143 abuts between two adjacent library plates 112.

[0096] In this embodiment, the library plate combination unit 111 for the top surface 103 of the power exchange station 100 is different from the library plate combination unit 111 for the side surface 104 of the power exchange station 100 described above. However, in other embodiments, the library plates 112 for the top surface 103 of the power exchange station 100 can also be used for the side surface 104, and the library plates 112 for the side surface 104 of the power exchange station 100 can also be used for the top surface 103. The two can be selected from using the same library plate combination unit 111 or can be in the form of interchanging the library plate combination units 111.

[0101] The covering plate 203 includes an inner wall 205 and an outer wall 209. A hollow cavity 215 is formed between the outer wall 209 and the inner wall 205. The edge of the outer wall 209 extends beyond the edge of the inner wall 205.

[0102] Heat insulation materials can be provided in the hollow cavity 215 of the corner piece 201 as needed. The edge of the outer wall 209 of the corner piece 201 extends beyond the edge of the inner wall 205, thereby preventing water from seeping in from both sides of the outer wall 209 of the corner piece 201 to a certain extent, achieving the effect of both waterproofing and heat insulation.

[0103] The connecting plate 217 is connected to the inner wall 205. A connecting member 219 is provided on the surface of the connecting plate 217 facing away from the hollow cavity 215.

The clamping surface 222 is used to abut against the clamping matching member 228 to connect and fix the corner protector 201. The guiding surface 221 and the clamping surface 222 are respectively arranged on opposite sides of the connecting plate 217. Preferably, the guiding surface 221 is inclined towards the clamping groove 223.

[0112] By providing the guiding surface 221 to guide the clamping matching member 228 into the clamping groove 223, it makes the assembly of the connecting member part and the clamping matching member 228 easier. Setting the guiding surface 221 to be inclined towards the clamping groove 223 can make it easier to snap the clamping matching member 228 into the clamping groove.

[0113] In this embodiment, taking the assembly of the corner guard 201 and the column 227 as an example, the connecting member engages with the engaging and matching member 228 of the column 227 so that the corner guard 201 and the column 227 are assembled.

[0123] Figures 12 - 14 Embodiment 3 according to the present invention illustrates a corner guard 301.

[0124] The corner wrap 301 includes: a covering plate 303 and a connecting plate 304. One end of the connecting plate 304 is connected to the inner surface of the covering plate 303. A connecting member 305 is provided on the connecting plate 304. The connecting member 305 is used to connect and fix the corner wrap 301 to the frame of the battery swapping station or the energy storage station. The edge of the covering plate 303 extends beyond the edge of the connecting plate 304. The part of the covering plate 303 that extends beyond the edge of the connecting plate 304 is used to cover the storage board 317.

[0125] The corner wrap 301 includes a mutually connected covering plate 303 and connecting plate 304, forming a generally T-shaped structure, which can facilitate the connection of two parallel storage boards 317. At the same time, a connecting member 305 is provided on the connecting plate 304 to connect the frame, which is beneficial to connecting the battery swapping station or the energy storage station into a whole. At the same time, the covering plate 303 covering the storage board 317 ensures the liquid tightness between the corner wrap 301 and the storage board 317.

[0126] The connecting member 305 is provided on the outer surface of the connecting plate 304 away from the covering plate 303.

[0127] The connecting plate 304 has a side surface adjacent to the inner surface of the covering plate 303. The connecting member 305 extends and protrudes from the side surface of the connecting plate 304 in a direction away from the side surface.

[0128] Optionally, the connecting plate 304 has an end surface at the other end away from the covering plate 303. The connecting member 305 extends and protrudes from the end surface of the connecting plate 304 in a direction away from the end surface.

[0129] The connecting member 305 is arranged in the above form, which is convenient for the assembly and connection between the corner wrap 301 and the frame.

[0130] The connecting member 305 is a buckle, and the buckle extends and protrudes outward from the outer surface of the connecting plate 304.

[0131] The connecting member 305 is arranged as a buckle, which can achieve snap connection and is convenient for modular assembly of the storage board 317.

[0132] The connecting member 305 includes a guiding surface 307 and a engaging surface 308. The guiding surface 307 is used to guide an engaging matching member 319 into an engaging groove 309 between the engaging surface 308 and the inner surface of the covering plate 303. The engaging surface 308 is used to abut against the engaging matching member 319 to connect and fix the corner wrap 301. The guiding surface 307 and the engaging surface 308 are respectively arranged on opposite sides of the connecting plate 304. Preferably, the guiding surface 307 is inclined towards the engaging groove 309.

[0133] By providing the guiding surface 307 to guide the engaging matching member 319 into the engaging groove 309, it makes it easier to assemble the connecting member and the engaging matching member 319. Setting the guiding surface 307 to be inclined towards the engaging groove 309 can more easily snap the engaging matching member 319 into the engaging groove.

[0134] In the third embodiment, taking the assembly of the corner guard 301 and the column 318 as an example, the connecting member engages with the engaging and mating member 319 of the column 318 so that the corner guard 301 and the column 318 are assembled.

[0135] In the third embodiment, the engaging and mating member 319 is an L-shaped member, but the present invention is not limited thereto, and the engaging and mating member 319 may also be a strip-shaped protrusion formed on the surface of the column 318.

[0136] When the corner guard 301 is assembled with other components on the frame, it is snap-connected to the corresponding engaging and mating member 319 on the other components.

[0137] The end face of the connecting plate 304 away from the covering plate 303 has a groove 311 recessed towards the covering plate 303.

[0138] During the process of the connecting member 305 being snapped into the notch of other members, the connecting member 305 is squeezed and thus moves closer to the middle. By providing the groove 311 between the two connecting members 305, it is convenient for the two connecting members 305 to be squeezed and snapped into the notch of the frame towards the middle. That is, the groove 311 makes the connecting plate 304 have a certain elasticity. In addition to the U-shaped groove shown in the figure, the groove 311 may also be a V-shaped groove.

[0139] The opening cross-section of the groove 311 is larger than the bottom cross-section of the groove 311, which is convenient for the connecting member 305 to be snapped into the frame while taking into account the connection strength of the corner guard 301.

[0140] Grooves 314 are provided on the inner surface of the covering plate 303, and sealing members are arranged in the grooves 314.

[0141] By arranging the sealing members on the inner surface of the covering plate 303, rainwater is prevented from seeping in from the contact surface between the covering plate 303 and the storage plate 317, improving the waterproof performance.

[0142] Optionally, grooves may also be provided on the opposite outer surfaces of the connecting plate 304, and sealing members are arranged in the grooves.

[0143] By providing grooves for preventing sealing members on the opposite outer surfaces of the connecting plate 304, rainwater is prevented from seeping in from the contact surface between the connecting plate 304 and the storage plate 317, improving the waterproof performance.

[0144] The grooves extend along the length direction of the corner guard 301 so as to improve the waterproof performance between the entire corner guard 301 and the storage plate 317.

[0145] The material of the corner guard 301 is aluminum alloy or plastic. Aluminum alloy and plastic are cheap and have high strength, which can improve the strength and reduce the production cost.

[0146] Optionally, the cover plate 303 may also include an inner wall and an outer wall, with a hollow cavity formed between the outer wall and the inner wall. The edge of the outer wall extends beyond the edge of the inner wall, and the connecting plate is connected to the inner wall. A heat-insulating layer can be arranged in the hollow cavity as needed. The heat-insulating layer is made of aerogel, rock wool, polyurethane foam material, etc. By arranging the heat-insulating layer in the hollow cavity, the heat-insulating performance of the corner 301 can be improved. The edge of the outer wall extends beyond the edge of the inner wall, thus preventing water from seeping in from both sides of the outer wall of the corner 301 to a certain extent, achieving the effect of both waterproofing and heat preservation.

[0147] The corner 301 is used to connect two adjacent storage panels 317 in the same plane.

[0148] Those skilled in the art should understand that the corners in Embodiment 2 and Embodiment 3 can be used to replace the corner in Embodiment 1.
