[0045] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0046] In the description of the present disclosure, it should be understood that the terms "upper", "lower", and the like indicate the orientation or positional relationship defined based on the direction of the energy storage cabinet in the normal use state, and are merely for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, a particular orientation configuration and operation, and therefore cannot be understood as a limitation on the present disclosure. For example, the upper and lower directions can be the upper and lower directions when the energy storage cabinet is normally placed, and the side of the energy storage cabinet close to or located on the ground is the lower side, and the side away from the ground is the upper side. In addition, the terms "inner" and "outer" refer to the inner and outer contours of the corresponding structures. In addition, the terms "first", "second", and the like are merely for distinguishing one element from another element, and do not have sequentiality and importance.

[0047] In the description of the present disclosure, it should be understood that, unless otherwise explicitly specified and limited, the terms "provided", "connected", "connected", "mounted" should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium; can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0048] As shown in FIGS. 1-12, the present disclosure provides, in a first aspect, a housing 10, which includes a cabinet door 100 and a cabinet body 200, one side of the cabinet body 200 is provided with an opening 11, one end of the cabinet door 100 is movably connected to the cabinet body 200 and is adapted to open or close the opening 11, for example, one end of the cabinet door 100 is hinged above the opening 11 of the cabinet body 200, and the cabinet door 100 is configured as an up-down opening door 100.

[0049] By the above scheme, the cabinet door 100 and the cabinet body 200 are configured as the cabinet door 100 of the up-down opening type, so that the cabinet door 100 will not cause the area of the opening 11 of the cabinet body 200 to become smaller when being opened or closed. At the same time, since the other end of the cabinet door 100 can be connected with the cabinet body 200 to close the opening 11, it is not necessary to provide a door column at the opening 11 of the cabinet body 200 for the cabinet door 100 to be connected, avoiding the door column occupying the space inside the cabinet body 200, so that the space inside the cabinet body 200 for accommodating the battery module 600 can be increased by canceling the door column, which is beneficial to increase the volume of the battery module 600 arranged in the shell 10 and improve the energy storage capacity of the energy storage cabinet 700.

[0050] It should be noted that the battery module 600 can include a battery pack and / or a battery pack, and the battery pack or the battery pack has battery cells 610. The movable connection mode of the cabinet door 100 and the cabinet body 200 includes but is not limited to hinged or sliding connection. As shown in FIGS. 1 and 5, the cabinet door 100 and the cabinet body 200 are hingedly connected, one end of the cabinet door 100 is hingedly connected with the cabinet body 200 through the first hinge 140, and the first hinge 140 is located above the opening 11, so that the cabinet door 100 can be opened by rotating upward to expose the opening 11, and closed by rotating downward to close the opening 11. Of course, when the sliding connection is used, a sliding groove arranged in the height direction can be provided on the cabinet body 200, and the cabinet door 100 is slidingly connected in the sliding groove to achieve the opening of the cabinet door 100 by sliding upward or the closing of the cabinet door 100 by sliding downward.

[0051] When the cabinet door 100 and the cabinet body 200 are hingedly connected, since the cabinet door 100 is rotated upward when the cabinet door 100 is in the open state, after the cabinet door 100 is opened, the cabinet door 100 can form a plate-shaped shielding structure, which can play a certain rainproof and sunproof function, so that the operator can stand below the shielding structure formed by the cabinet door 100 to operate the battery module 600 in the cabinet body 200, and thus the energy storage cabinet 700 formed by the shell 10 can be used in outdoor environment.

[0052] In addition, the shell 10 can be configured as a part of the energy storage cabinet 700. In the drawings provided in the embodiment, the cabinet body 200 in the shell 10 shows a frame structure. In actual application, a skin or a decorative plate is further arranged on the outer surface or the inner surface of the cabinet body 200, so that the surface of the cabinet body 200 can form a relatively closed structure by taking the frame structure as the installation basis of the skin or the decorative plate, and the cabinet door 100 is configured to form the energy storage cabinet 700, and the inside is configured to form the accommodation cavity 250 for accommodating the battery module 600. Then, a plurality of energy storage cabinets 700 can be connected to form the energy storage device 1000. Of course, when the shell 10 is a plurality of shells, the plurality of shells 10 can be arranged side by side and connected together, and then the skin or the decorative plate is arranged to form the energy storage cabinet 700 device. In this way, the accommodation cavities 250 between the plurality of shells 10 arranged side by side can be connected to each other.

[0053] It should be noted that the opening of the cabinet body 200 is communicated with the accommodation cavity 250 inside the cabinet body 200, and the accommodation cavity 250 is used for placing the battery module 600.

[0054] In some optional embodiments, the cabinet body 200 includes a first door body 110 and a second door body 120. The first end of the first door body 110 is hinged to the cabinet body 200, and the second end of the first door body 110 is hinged to the first end of the second door body 120, so that the cabinet door 100 is configured as an up-down folding cabinet door 100.

[0055] The first door body 110 and the second door body 120 in the cabinet door 100 are folded up and down, so that when the cabinet door 100 is opened, the second door body 120 is folded relative to the first door body 110 to shorten the opening length of the cabinet door 100 after being opened. Therefore, when the energy storage cabinet 700 is arranged in multiple rows, the gap between the adjacent two rows of shells 10 can be shortened, so that the gap between the two rows of energy storage cabinets 700 is shortened, and the energy storage cabinet 700 is arranged more compactly. When the cabinet door 100 is closed, the first door body 110 and the second door body 120 are in an unfolded state.

[0056] It should be noted that when the gap between the adjacent two rows of energy storage cabinets 700 is large enough or only one row of energy storage cabinets 700 is arranged, the second door body 120 can be selectively not folded relative to the first door body 110 when the cabinet door 100 is opened, that is, the first door body 110 and the second door body 120 remain unfolded after the cabinet door 100 is opened. In this way, a larger shielding structure can be formed, and a larger shielding area can be obtained. The first door body 110 is hinged to the cabinet body 200 through the first hinge 140, and the first door body 110 is hinged to the second door body 120 through the second hinge 150.

[0057] Since the energy storage cabinet 700 formed by the shell 10 needs to be sealed when used outdoors, so as to ensure that the battery module 600 inside the cabinet 700 can normally operate. In view of this, in some optional embodiments of the present disclosure, a first sealing structure 300 is arranged on the cabinet door 100, and the first sealing structure 300 is adapted to seal the first gap 130 between the second end of the first door body 110 and the first end of the second door body 120. When the cabinet door 100 is in a closed state, the first sealing structure 300 seals the first gap 130 to prevent liquid (such as rainwater) or solid (such as dust) from entering the inside of the shell 10 from the first gap 130.

[0058] It should be noted that when the cabinet door 100 is in an open state and the first door body 110 and the second door body 120 are unfolded, the first sealing structure 300 can also seal the first gap 130 to prevent rainwater from dripping from the first gap 130 when the cabinet door 100 is in a folded structure.

[0059] For the specific structure of the first sealing structure 300, as shown in FIGS. 2-4, the first sealing structure 300 can include a first sealing member 310 and a second sealing member 320, both of which are adapted to seal the first gap 130. The cabinet door 100 has an inner side surface 170 adapted to close the opening 11, and the second sealing member 320 is closer to the inner side surface 170 than the first sealing member 310. The first sealing member 310 and the second sealing member 320 can form a double-sealing effect at the first gap 130 to improve the sealing performance of the first gap 130 between the first door body 110 and the second door body 120.

[0060] Here, the inner side surface 170 can also be understood as the surface of the cabinet door 100 facing the accommodation cavity 250 or constituting the accommodation cavity 250 in the closed state of the cabinet door 100.

[0061] Of course, in other optional embodiments, the first sealing structure 300 can also include only the first sealing member 310 or the second sealing member 320, and achieve sealing of the first gap 130 through the first sealing member 310 or the second sealing member 320. Alternatively, the first sealing structure 300 can also include another sealing member for sealing the first gap 130 to form a triple or more sealing at the first gap 130, which is not specifically limited by the present disclosure.

[0062] It should be noted that the first sealing member 310 can be fixed on any one of the first door body 110 and the second door body 120, and the second sealing member 320 can be fixed on any one of the first door body 110 and the second door body 120, which is not specifically limited by the present disclosure.

[0063] In some optional embodiments, the first seal 310 and the second seal 320 can each be an elastic seal to achieve better sealing effect through deformation of the elastic seal. Of course, in other embodiments, the first seal 310 and the second seal 320 can also be rigid seals to achieve sealing through surface contact sealing.

[0064] To improve the sealing effect of the first seal 310 and the second seal 320 on the first gap 130, as shown in FIGS. 2-4, the first seal 310 is adapted to be fixed to the second end of the first door body 110 and adapted to be in pressure sealing contact with the first end of the second door body 120; the second seal 320 is adapted to be fixed to the first end of the second door body 120 and adapted to be in pressure sealing contact with the second end of the first door body 110; wherein, when the cabinet door 100 is in a closed state, the position of the first seal 310 in pressure sealing contact with the second door body 120 is lower than the position of the second seal 320 in pressure sealing contact with the first door body 110.

[0065] Fixing the first seal 310 to the second end of the first door body 110 causes sealing between the first seal 310 and the second end of the first door body 110, and the gap between the first seal 310 and the first end of the second door body 120 constitutes a first gap segment of the first gap 130. Fixing the second seal 320 to the first end of the second door body 120 causes sealing between the second seal 320 and the first end of the second door body 120, and the gap between the second seal 320 and the second end of the first door body 110 constitutes a second gap segment of the first gap 130. By setting the position of the first seal 310 in pressure sealing contact with the second door body 120 to be lower than the position of the second seal 320 in pressure sealing contact with the first door body 110, the first gap segment is located lower than the second gap segment. Since a liquid or a solid generally does not have the ability to move upward by relying only on its own gravity, the liquid or the solid outside the housing 10 cannot enter the cabinet body 200 through the first gap segment and the second gap segment, thereby further improving the sealing effect at the first gap 130.

[0066] As shown in FIGS. 2-4, in some optional embodiments, the first sealing structure 300 further comprises a first protrusion 340, the first protrusion 340 is arranged to protrude from the end face 121 of the first end of the second door body 120, and the second seal 320 is arranged on the first protrusion 340. By arranging the first protrusion 340, the first protrusion 340 can protrude from the end face 111 of the second end of the second door body 120. After the liquid or the solid enters the first gap 130, it needs to move upward to pass over the first protrusion 340 to possibly reach the accommodation cavity 250. Thus, the first protrusion 340 can improve the sealing effect of the first gap. Even if the second seal 320 fails, the first protrusion 340 still has a certain sealing effect.

[0067] In some optional embodiments, the first protrusion 340 is integrally formed with the second door body 120 to improve the connection strength and sealing effect between the first protrusion 340 and the second door body 120. Of course, in other embodiments, the first protrusion 340 and the second door body 120 can also be connected by other connection methods such as bolting, bonding, etc. The second sealing member 320 can be fixed on the first protrusion 340 in a detachable manner, for example, by clamping or bolting.

[0068] In order to further improve the sealing effect on the first gap 130, as shown in FIGS. 2 to 4, in some optional embodiments, the first sealing structure 300 further comprises a second protrusion 330. The second protrusion 330 is arranged to protrude from the end surface 111 of the second end of the first door body 110. The second protrusion 330 cooperates with the first protrusion 340 to make the first gap 130 have an inclined gap section 131 extending obliquely upward from the outside to the inside. The first sealing member 310 is arranged on the second protrusion 330, and the second sealing member 320 is arranged on the first protrusion 340.

[0069] The second protrusion 330 is arranged to cooperate with the first protrusion 340 to form the inclined gap section 131 extending obliquely upward from the outside to the inside, which can prevent liquid or solid from entering the inside of the cabinet body 200. Even if the first sealing member 310 and / or the second sealing member 320 fails, the inclined gap section 131 still exists.

[0070] It should be noted that here, from the outside to the inside, refers to from the outer side of the cabinet door 100 to the inner side 170 of the cabinet door 100. The outer side of the cabinet door 100 is arranged opposite to the inner side 170 of the cabinet door 100.

[0071] In some optional embodiments, the second protrusion 330 is integrally formed with the first door body 110 to improve the connection strength and sealing effect between the second protrusion 330 and the first door body 110. Of course, in other embodiments, the second protrusion 330 can also be fixed on the first door body 110 by welding, bolting, etc. The first sealing member 310 can be fixed on the second protrusion 330 in a detachable manner, for example, by clamping or bolting.

[0072] As shown in FIG. 4, in some optional embodiments, the second protrusion 330 has, from outside to inside, a first mounting surface 331, a first inclined surface 332 and a first pressing surface 333 connected in sequence. The first protrusion 340 has, from outside to inside, a second pressing surface 341, a second inclined surface 342 and a second mounting surface 343 connected in sequence. The first sealing member 310 is fixed to the first mounting surface 331 and is adapted to be pressed and sealed with the second pressing surface 341, and the second sealing member 320 is fixed to the second mounting surface 343 and is adapted to be pressed and sealed with the first pressing surface 333. The first inclined surface 332 and the second inclined surface 342 are oppositely arranged to form the inclined gap section 131.

[0073] By providing the first mounting surface 331 as a mounting basis for the first sealing member 310, the first sealing member 310 is pressed and sealed with the second pressing surface 341, and by providing the second mounting surface 343 as a mounting basis for the second sealing member 320, the second sealing member 320 is pressed and sealed with the first pressing surface 333, the sealing positions of the first sealing member 310 and the first pressing surface 333 and the sealing positions of the second sealing member 320 and the second pressing surface 341 can be separated by the inclined gap section 131. Even if the first sealing member 310 fails to seal, liquid cannot directly flow to the second sealing member 320 along the first sealing member 310.

[0074] As shown in FIGS. 1-3, in some optional embodiments, the cabinet door 100 is provided with a second sealing structure 400 adapted to seal the first gap 130 between the first door body 110 and the second door body 120. The second sealing structure 400 includes a first panel 410, which includes a first portion 411 adapted to be arranged on the outer side surface 112 of the first door body 110 and a second portion 412 adapted to be attached to the outer side surface of the second door body 120.

[0075] In this way, when the first door body 110 and the second door body 120 are folded, the first panel 410 is arranged on the first door body 110 through the first portion 411 and moves with the first door body 110. When the cabinet door 100 is in a closed state, the second portion 412 of the first panel 410 is attached to the outer side surface of the second door body 120 to achieve sealing, so that the first panel 410 can block the connection position of the first door body 110 and the second door body 120, play a blocking and sealing role on the first gap 130, reduce the probability of liquid and solid entering the first gap 130, and improve the sealing effect on the first gap 130.

[0076] It should be noted that the outer side surface 112 of the first door body 110 is also a component of the outer side surface of the cabinet door 100; the inner side surface of the first door body 110 is also a component of the inner side surface 170 of the cabinet door 100. In addition, the outer side surface of the second door body 120 is also a component of the outer side surface of the cabinet door 100; the inner side surface of the second door body 120 is also a component of the inner side surface 170 of the cabinet door 100. In addition, when the first sealing structure 300 and the second sealing structure 400 are arranged on the cabinet door 100 at the same time, the sealing effect on the first gap 130 can be improved.

[0077] Optionally, the first panel 410 is a decorative plate. When the decorative plate of the cabinet door 100 is used as the first panel 410, the first panel 410 can be used in two ways, that is, the first panel 410 can not only shield and seal the first gap 130, but also improve the appearance of the cabinet door 100.

[0078] As shown in FIGS. 2 and 3, in some optional embodiments, the outer side of the second door body 120 is provided with a second panel 420, when the first panel 410 is attached to the outer side wall of the second door body 120, one end of the first panel 410 is connected to one end of the second panel 420, so that the second panel 420 cooperates with the first panel 410 to improve the sealing effect on the first gap 130.

[0079] Optionally, the second panel 420 can also be a decorative plate.

[0080] As shown in FIGS. 5 to 10, in some optional embodiments, the shell 10 is provided with a third sealing structure 500, when the cabinet door 100 is in a closed state, the third sealing structure 500 is adapted to seal the gap between the cabinet 200 and the cabinet door 100 (hereinafter referred to as the second gap). After the third sealing structure 500 seals the second gap, it can prevent liquids and solids from entering the cabinet 200 from the second gap, further improving the sealing effect of the shell 10.

[0081] Optionally, as shown in FIGS. 6 and 7, the third sealing structure 500 includes a third sealing member 510 and a fourth sealing member 520, the third sealing member 510 is arranged to extend along the length direction or the width direction of the opening 11, and the fourth sealing member 520 is configured in a U-shaped structure, when the cabinet door 100 is in a closed state, the two ends of the third sealing member 510 are sealingly connected to the two ends of the fourth sealing member 520 to form a ring-shaped structure and are adapted to seal the second gap between the cabinet 200 and the cabinet door 100. The ring-shaped structure can ensure the sealing between the cabinet 200 and the cabinet door 100.

[0082] It should be noted that the third sealing member 510 extends along the length direction or the width direction of the opening 11 according to the size of the opening 11. When the size of the opening 11 in the height direction of the cabinet 200 is greater than the size of the opening 11 in the direction perpendicular to the height direction of the cabinet 200, the third sealing member 510 extends along the width direction of the opening 11. When the size of the opening 11 in the height direction of the cabinet 200 is less than the size of the opening 11 in the direction perpendicular to the height direction of the cabinet 200, the third sealing member 510 extends along the length direction of the opening 11. It can also be understood that the third sealing member 510 extends generally along the direction perpendicular to the height direction of the cabinet 200. The third sealing member 510 and the fourth sealing member 520 can be both arranged on the cabinet door 100, or both arranged on the cabinet 200, or one of the third sealing member 510 and the fourth sealing member 520 is arranged on the cabinet door 100 and the other is arranged on the cabinet 200, which is not specifically limited by the present disclosure. The annular structure formed by the third sealing member 510 and the fourth sealing member 520 can be located outside the opening of the cabinet door 100, i.e. the opening of the cabinet door 100 is located in the area enclosed by the annular structure, so that when the cabinet door 100 is in the closed state, the opening of the cabinet door 100 is isolated from the outside through the sealing between the third sealing structure 500 and the cabinet door 100 and the cabinet 200, achieving the effect of preventing liquid or solid from entering the cabinet 200 from the second gap. Of course, in other embodiments, the annular structure formed by the third sealing member 510 and the third sealing member 510 can also be located on the inner side wall of the opening 11, and the sealing of the containing cavity 250 is achieved by inserting the cabinet door 100 into the opening 11.

[0083] As shown in FIGS. 5-7, in some optional embodiments, the inner side surface 170 of the cabinet door 100 is provided with a first mounting member 160 extending along the length direction or width direction of the opening 11, and a first flow guide groove 161 with an upward opening is formed in the first mounting member 160. The third sealing member 510 is mounted on the side of the first mounting member 160 away from the first door body 110, and the top of the third sealing member 510 is not lower than the opening of the first flow guide groove 161. When the cabinet door 100 is in the closed state, the third sealing member 510 is adapted to press seal the gap between the cabinet door 100 and the corresponding part of the cabinet body 200. The first mounting member 160 is provided on the housing 10, which can provide a mounting basis for the third sealing member 510, so that the third sealing member 510 can be mounted and fixed with the cabinet door 100 by being fixed on the first mounting member 160. By arranging the third sealing member 510 on the side of the first mounting member 160 away from the cabinet door 110 and arranging the top of the third sealing member 510 to be not lower than the opening of the first flow guide groove 161 formed in the first mounting member 160, when the third sealing member 510 is press sealed with the cabinet body 200, the liquid entering from the gap between the cabinet door 100 and the cabinet body 200 will flow into the first flow guide groove 161 through the third sealing member 510, and then be guided by the first flow guide groove 161 to other positions for drainage, for example, to the drain groove 231 shown in FIG. 8. At the same time, it also avoids the formation of a concave structure between the top of the third sealing member 510 and the first mounting member 160 caused by the third sealing member 510 being lower than the opening of the first flow guide groove 161, which in turn causes the rainwater to not flow smoothly into the first flow guide groove 161.

[0084] It should be noted that when the cabinet door 100 includes the first door body 110 and the second door body 120, and the first end of the first door body 110 is hinged to the cabinet body 200 and the second end of the first door body 110 is hinged to the first end of the second door body 120, the above-mentioned first mounting member 160 is arranged on the inner side surface of the first door body 110. The third sealing member 510 can be fixed on the first mounting member 160 by clamping, specifically, as shown in FIG. 7, the third sealing member 510 can be clamped on the side of the first mounting member 160 away from the cabinet door 110. Of course, the third sealing member 510 can also be fixed on the first mounting member 160 by bonding or bolt press sealing.

[0085] It should be noted that the gap between the third sealing member 510 and the corresponding part of the cabinet body 200 refers to the gap between the part of the cabinet door 100 provided with the third sealing member 510 and the corresponding part of the cabinet body 200.

[0086] As shown in FIGS. 5-7, in some optional embodiments, the cabinet body 200 has a crossbeam 210 adapted to be sealingly pressed against the third sealing member 510, the crossbeam 210 being located near the upper end of the cabinet body 200, and the cabinet body 200 is provided with a second flow guide groove 221, the opening of the second flow guide groove 221 being upwardly directed and located below the position where the third sealing member 510 is sealingly pressed against the cabinet body 200. The second flow guide groove 221 receives the liquid flowing from between the third sealing member 510 and the cabinet body 200 due to failure of the sealing, so as to prevent the liquid from directly dripping into the interior of the cabinet body 200.

[0087] Optionally, the cabinet body 200 is provided with a second mounting member 220, and the second flow guide groove 221 is formed in the second mounting member 220. Of course, in other embodiments, the second flow guide groove 221 can also be formed directly in the cabinet body 200.

[0088] As shown in FIG. 7, in some optional embodiments, the lower end of the crossbeam 210 extends downwardly to form a first flow guide plate 211, the lower end of the first flow guide plate 211 being projected into the opening of the second flow guide groove 221, and at least a portion of the third sealing member 510 is adapted to be sealingly pressed against the first flow guide plate 211. The first flow guide plate 211 can guide the liquid, so as to guide the leaked liquid into the second flow guide groove 221 when the sealing between the third sealing member 510 and the cabinet body 200 fails, and further prevent the liquid from flowing along the surface of the crossbeam 210 into the cabinet body 200.

[0089] As shown in FIG. 7, in some optional embodiments, the cabinet door 100 is provided with an obliquely arranged second flow guide plate 170, the first end of the second flow guide plate 170 being connected to the cabinet door 100, and the second end of the second flow guide plate 170 extending away from the cabinet door 100, the position of the second end being lower than that of the first end when the cabinet door 100 is in the closed state. The second flow guide plate 170 is used to guide the liquid into the opening of the second flow guide groove 221.

[0090] It should be noted that when the cabinet door 100 includes the first door body 110 and the second door body 120, and the first end of the first door body 110 is hingedly connected to the cabinet body 200 and the second end of the first door body 110 is hingedly connected to the first end of the second door body 120, the second flow guide plate 170 is also provided on the first door body 110, so as to relatively fix the first door body 110 with the first mounting member 160.

[0091] Optionally, the first flow guide plate 211 and the second flow guide plate 170 are oppositely arranged, and a flow channel for the liquid is defined between the first flow guide plate 211 and the second flow guide plate 170, so as to guide the leaked liquid to enter the second flow guide groove 221 through the flow channel when the third sealing member 510 fails to seal.

[0092] As shown in FIG. 10, in some optional embodiments, a fourth sealing member 520 is arranged outside the opening 11 of the cabinet body 200, and the two ends of the fourth sealing member 520 are adapted to be connected with the two ends of the third sealing member 510 to form an annular structure for sealing the second gap between the cabinet body 200 and the cabinet door 100. At least one side of the cabinet door 100 is provided with a water guide plate 230, which is arranged outside the fourth sealing member 520 and spaced apart from the fourth sealing member 520, and the water guide plate 230, part of the fourth sealing member 520 and the cabinet body 200 jointly form a drainage groove 231, and the first flow guide groove 161 and / or the second flow guide groove 221 are in communication with the drainage groove 231.

[0093] When the cabinet door 100 is in the closed state, the two ends of the fourth sealing member 520 are connected with the two ends of the third sealing member 510 to form an annular structure, which is press-sealed between the cabinet door 100 and the cabinet body 200, thereby achieving sealing of the second gap between the cabinet door 100 and the cabinet body 200, preventing liquid or solid from entering the cabinet body 200 through the second gap. The drainage groove 231 can receive the liquid in the first flow guide groove 161 and / or the second flow guide groove 221 to drain the liquid outside the energy storage cabinet 700.

[0094] It should be noted that the upper end and the lower end of the drainage groove 231 are both open ends, and the liquid flowing out of the first flow guide groove 161 and / or the second flow guide groove 221 can enter the drainage groove 231 from the upper end of the drainage groove 231, and then directly flow to the installation base such as the ground of the energy storage cabinet 700 from the lower end of the drainage groove 231. Of course, the lower end of the drainage groove 231 can also be in communication with other drainage structures to drain the liquid through the other drainage structures. The communication position of the first flow guide groove 161 with the drainage groove 231 can be at the end of the first flow guide groove 161, or at a position other than the end (for example, an opening in the groove bottom near the end of the first flow guide groove 161), and the communication position of the second flow guide groove 221 with the drainage groove 231 can be at the end of the first flow guide groove 161, or at a position other than the end (for example, an opening in the groove bottom near the end of the second flow guide groove 221).

[0095] As shown in FIGS. 8 and 10, in some optional embodiments, at least one side of the open end of the cabinet body 200 is provided with a water baffle 240, which is used to block the gap between the cabinet door 100 and the corresponding side wall of the cabinet body 200 when the cabinet door 100 is in the closed state. The water baffle 240 can block the rainwater or splashed liquid falling on the side of the energy storage cabinet 700, preventing the rainwater or splashed liquid from entering the second gap. Thus, the sealing effect of the second gap is improved to some extent.

[0096] Optionally, when the door is in the closed state, the side wall of the cabinet door 100 is attached to the weather strip 240, so as to further improve the blocking effect on rain or splashed liquid.
