If battery replacement is to be realized, a battery swap station needs to be provided, and the vehicle realizes battery replacement in the battery swap station. Since the battery swap station needs to be powered, the waterproofness requirement is high. Once rainwater or snowwater enters the battery swap station from the outside, there is a risk of electric leakage or short circuit of the battery swap station. How to improve the waterproofness of the battery swap station is an important problem. The existing warehouse board combination unit has poor waterproofness, and the battery swap station has a risk of electric leakage or short circuit. The existing technology CN202324387U discloses a building roof panel with waterproof and heat preservation functions, which comprises a base layer.

The third end and the fourth end of the library plate form a closed structure by abutting against each other through the first surrounding plate and the second surrounding plate, so that liquid cannot penetrate into the interior of the library plate from the two ends, and at the same time, the first surrounding plate 413 and the second surrounding plate 423 abut against the gusset, which can prevent liquid from penetrating from the connection position between the library plate and the gusset, thereby improving the waterproofness and the connection strength of the library plate combination unit.

[0185] As shown in Figure 27As shown, in the embodiment, the outer surface of the first surrounding plate 413 is provided with a sealing abutting portion (not shown in the figure). The sealing abutting portion is a groove opened on the connecting surface of the first surrounding plate 413 and the second surrounding plate 423. The sealing abutting portion can further improve the waterproof effect of the third end 503 and the fourth end 504 of the battery tray 112 by abutting the sealing member thereon.

[0186] In other embodiments, the sealing abutting portion can also be provided on the second surrounding plate 423 or in other structural forms.

[0187] The battery tray 112 of the embodiment includes a first layer plate 410 and a second layer plate 420. The first layer plate 410 and the second layer plate 420 are attached to each other to form the side plate battery tray 112. Figure 20 、 21 , 23, 25, Figure 23 is a structural schematic view of the second layer plate 420, showing the inside of the second layer plate 420, Figure 25 is a structural schematic view of the first layer plate 410, showing the inside of the first layer plate 410. The side plate battery tray 112 is in the shape of a rectangle, each side of which corresponds to an end. The first end 501 and the second end 502 are arranged opposite to each other, and the third end 503 and the fourth end 504 are arranged opposite to each other.

[0188] At the first end 501, the first layer plate 410 is provided with a first protruding portion 411 which protrudes along the extension direction of the first layer plate 410 and beyond the edge of the second layer plate 420. At the second end 502, the second layer plate 420 is provided with a second protruding portion 421 which protrudes along the extension direction of the second layer plate 420 and beyond the edge of the first layer plate 410. The first protruding portion 411 is used to cover the second protruding portion 421 of the adjacent battery tray 112 when a plurality of battery trays 112 are assembled. When the two battery trays 112 are connected, the first protruding portion 411 and the second protruding portion 421 are attached to each other.

[0189] When a plurality of battery trays are connected longitudinally, the first protruding portion and the second protruding portion are staggered, which can prevent external liquid from directly penetrating into the charging station from the gap between the longitudinally connected battery trays.

[0190] In the embodiment, the battery tray 112 adopts a multi-layer structure. The first layer plate 410 and the second layer plate 420 on the outer side are tightly connected through the first protruding portion 411 and the second protruding portion 421 which extend out at the connecting position. The first protruding portion 411 and the second protruding portion 421 are staggered when the battery tray 112 is connected. When a plurality of battery trays 112 are spliced, the side edges of the battery trays 112 can be attached to each other. The connecting gap between the battery trays 112 will not directly lead to the inside of the battery swapping station. Therefore, the water tightness is better, and external liquid cannot directly penetrate into the charging station from the gap between the connected battery trays 112.

[0191] As Figure 20 , 21 shown, the library plate combination unit 111 of the embodiment is formed by splicing multiple library plates 112, and the first end of the upper library plate 112 covers the second end of the adjacent lower library plate 112.

[0192] In the embodiment, the library plate combination unit connects multiple library plates through mutual connection between the library plates and through the corner cover. The corner cover can connect the library plates in the transverse direction, improve the strength of the library plate combination unit, cover the joints between the library plates, ensure the water tightness between the library plates and the corner cover, and improve the waterproofness of the library plate combination unit. Meanwhile, the corner cover connects the third end and the fourth end of the library plate, which can avoid the structure of the library plate extension part causing the corner cover to not fully fit the library plate, resulting in reduced waterproofness at the connection between the library plate and the corner cover. Thus, the waterproofness of the library plate combination unit is improved.

[0193] As Figure 20 , 21 , 23, 25 shown, Figure 23 is a structural schematic diagram of the second layer plate 420, showing the inside of the second layer plate 420, Figure 25 is a structural schematic diagram of the first layer plate 410, showing the inside of the first layer plate 410. The library plate 112 of the embodiment includes the first layer plate 410 and the second layer plate 420, and the first layer plate 410 and the second layer plate 420 are attached in a top-to-bottom manner to form the side plate library plate 112, which is a rectangular shape, each side of which corresponds to an end. Among them, the first end 501 and the second end 502 are arranged opposite to each other, and the third end 503 and the fourth end 504 are arranged opposite to each other.

[0194] As Figure 20 , 21 shown, in the embodiment, at the first end 501, the edge part of the second layer plate 420 is bent and extended in the direction of the first layer plate 410 to form a second bending part 422, and the first extension part 411 abuts against the second bending part 422. At the second end 502, the edge part of the first layer plate 410 is bent and extended in the direction of the second layer plate 420 to form a first bending part 412, and the second extension part 421 abuts against the first bending part 412. The first bending part 412 and the second bending part 422 are at a right angle with the layer plate and are opposite to each other, and respectively abut against the first extension part 411 and the second extension part 421 at both ends, so as to completely close the library plate 112 at the first end 501 and the second end 502. This liquid cannot penetrate into the inside of the library plate 112 from the two ends, and will not damage the thermal insulation layer 430 or penetrate into the battery swap station through the library plate 112.

[0195] As Figure 21As shown, in the present embodiment, at the first end 501, the first protruding part 411 has a first protruding part 416 extending protruding from the inner surface of the first layer plate 410 towards the second layer plate 420. At the second end 502, the second protruding part 421 has a second protruding part 426 extending protruding from the inner surface of the second layer plate 420 towards the first layer plate 410. The first protruding part 416 and the second protruding part 426 protrude to a height that is just enough to abut against the second bending part 422 and the first bending part 412 respectively, and the two protruding parts can also abut against each other, so that when the adjacent storage plates 112 are connected, the first protruding part 416 and the second protruding part 426 of the two storage plates 112 abut against each other, and at the same time, the first protruding part 416 and the second protruding part 426 also abut against the first bending part 412 and the second bending part 422 (as shown in FIG. 4B), facilitating the assembly of the plurality of storage plates 112 and improving the waterproof sealing performance of the storage plate combination unit 111. Figure 21 As shown, in the present embodiment, the first protruding part 411 and the second protruding part 421 protrude to the same length, so that the first layer plate 410 and the second layer plate 420 are symmetrical to each other and have consistent structures, facilitating the production and replacement of the layer plates, and at the same time, the connection effect is better. In other embodiments, the first protruding part 411 and the second protruding part 421 can also protrude to different lengths.

[0196] In the present embodiment, the thickness of the first protruding part 416 and the second protruding part 426 is consistent. This facilitates the production and replacement of the layer plates, and at the same time, the connection effect is better. In other embodiments, the thickness of the first protruding part 416 and the second protruding part 426 can also be inconsistent.

[0197] In the present embodiment, when the two storage plates 112 are connected, one side of the first protruding part 411 abuts against the first bending part 412 of the adjacent storage plate 112, and the other side simultaneously abuts against the second bending part 422 of the same storage plate 112 and the second protruding part 421 of the adjacent storage plate 112. At the same time, one side of the first bending part 412 abuts against the first protruding part 411 of the adjacent storage plate 112, and the other side abuts against the second protruding part 421 of the same storage plate 112. This achieves a tight connection at the connection of the storage plates 112 and improves the waterproof performance.

[0198] In other embodiments, the connection mode of the protruding part and the bending part can also not be limited to this, as long as the connection part has an interleaved structure.

[0199] In the present embodiment, the end of the first protruding part 411 and the second protruding part 421 is provided with a sealing member (not shown in the figure). The sealing member is filled between the end surfaces of the first protruding part 411 and the second protruding part 421 in contact. The sealing member arranged between the protruding parts can further improve the waterproof effect of the storage plate 112.

[0200] In the present embodiment, the end of the first protruding part 411 and the second protruding part 421 is provided with a sealing member (not shown in the figure). The sealing member is filled between the end surfaces of the first protruding part 411 and the second protruding part 421 in contact.

[0201] Meanwhile, the end surface of the first protruding part 411 opposite to the adjacent battery plate 112 is provided with a sealing member (not shown in the figure). The sealing member is filled between the first protruding part 411 and the first bending part 412 of the adjacent battery plate 112, and between the first protruding part 411 and the second protruding part 421 of the adjacent battery plate 112. The sealing member is arranged on the end surface of the first protruding part 411 opposite to the adjacent battery plate 112, which can further enhance the waterproof effect of the contact position of the two battery plates 112, and the multi-point waterproofing makes the overall waterproofness of the battery plate 112 better.

[0202] In other embodiments, the sealing member can also be arranged on the outer side, the inner side or other connection positions of the battery plate 112. Meanwhile, the sealing member can also be made of other materials.

[0203] In the embodiment, the materials of the first layer plate 410 and the second layer plate 420 are carbon fiber or high polymer composite material or SMC resin material. The carbon fiber or high polymer composite material or SMC resin material has light weight and high strength. The use of the above-mentioned materials to form the battery plate can improve the structural strength of the battery plate combination unit and reduce the weight of the battery swap station or energy storage station, which is convenient for transportation.

[0204] In other embodiments, the material of the layer plate can also be selected from other materials.

[0205] As shown in Figure 20 , 21 , the battery plate 112 further comprises a first connecting column 414 and a second connecting column 424.

[0208] In other embodiments, only the first connecting columns 414 or the second connecting columns 424 can be arranged between the layer plates.

[0209] In the embodiment, the first connecting columns can be integrally formed with the first layer plate, and the second connecting columns can be integrally formed with the second layer plate.

[0210] In other embodiments, the first connecting columns and the second connecting columns can be respectively made and fixed with the first layer plate and the second layer plate by bonding, welding or other methods.

[0211] In the embodiment, the materials of the first connecting columns 414 and the second connecting columns 424 are resin materials. The resin materials are light in weight, high in strength and convenient to produce by mold pouring.

[0212] In other embodiments, the first connecting columns 414 and the second connecting columns 424 can also be made of other materials meeting the requirements of strength and quality.

[0213] In the embodiment, the battery plate 112 further comprises a thermal insulation layer 430, the thermal insulation layer 430 is arranged between the first layer plate 410 and the second layer plate 420. The thermal insulation layer 430 is filled between the first layer plate 410 and the second layer plate 420 of the battery plate 112.

[0215] In other embodiments, the thermal insulation layer 430 can also be made of rock wool, polyurethane foam or other thermal insulation materials.

[0216] As Figure 21As shown, the thermal insulation layer 430 of the embodiment also has a plurality of through holes 431 corresponding to the positions of the first connecting column and the second connecting column, and the first connecting column and the second connecting column are connected and fixed through the through holes 431.

The assembly hole 415 is not directly provided on the surface of the library plate 112, but is provided in the column in the library plate 112, such as the first connecting column or the second connecting column. This setting method does not affect the structural strength of the library plate 112, and at the same time facilitates the rapid installation of the library plate on the frame.
