Description

Technical Field

[0001] This application relates to the technical field of energy storage, and particularly to a housing device and an energy storage device. Background Art

[0002] For the upper cover part of an energy storage device, sometimes, due to considerations of industrial design aesthetics, it is designed as a split structure. For example, the upper cover is a combined structure of an outer frame and a face cover. There will be a gap between the two split parts. When water accumulates on the top of the energy storage device, water easily enters through the gap, thereby entering the interior of the energy storage device to erode electrical components or cause electrical components to short-circuit, resulting in potential safety hazards for the energy storage device. Summary of the Utility Model

[0003] In view of this, this application provides a housing device and an energy storage device, which can improve the waterproof performance of the energy storage device and enhance the safety of using the energy storage device.

[0004] An embodiment of this application provides a housing device applied to an energy storage device. The housing device includes a cover body and a housing. The cover body includes an outer frame and a face cover. The inner edge of the outer frame is formed with a first ring edge and a second ring edge in a stepped manner from top to bottom. The face cover is arranged in the area surrounded by the first ring edge, and a gap is formed at the junction with the first ring edge. The second ring edge is formed with a water diversion structure. The water diversion structure is arranged along the extending direction of the second ring edge, and a drainage port communicating with the outside is formed at the end of the water diversion structure. The water diversion structure is configured to receive and guide the water flowing down from the gap to the drainage port. The housing and the cover body are buckled to form a containing cavity at least for containing the battery pack of the energy storage device.

[0005] In the above housing device, when water accumulates on the cover body, the water can flow from the gap to the water diversion structure on the second ring edge. Under the guiding action of the water diversion structure, the water flow can flow to the drainage port and flow to the outside from the drainage port, thereby reducing the accumulated water on the cover body, improving the waterproof performance of the energy storage device, and enhancing the safety of using the energy storage device.

[0006] In at least one embodiment, the second ring edge has a bearing surface facing the face cover. The water diversion structure includes a diversion strip. The diversion strip is arranged on the bearing surface and along the extending direction of the second ring edge. A diversion channel is formed between the diversion strip and the first ring edge. A drainage port is formed among the end of the diversion strip, the bearing surface, and the first ring edge.

[0007] In the above embodiments, the accumulated water on the cover body can enter the diversion channel through the gap. The diversion channel can accommodate water flow, and the diversion strip can restrict the water flow from flowing towards the direction away from the first ring edge, reducing the risk of water flow entering the energy storage device. The water flow in the diversion channel can flow along the extension direction of the diversion strip towards the drain outlet and be discharged to the outside from the drain outlet, thereby realizing the discharge of the accumulated water on the cover body. Through the diversion of the diversion strip and the drainage function of the drain outlet, the waterproof performance of the energy storage device is improved, thereby reducing the risk of water flow entering the accommodation cavity and improving the use safety of the energy storage device.

[0008] In at least one embodiment, the height of the diversion strip gradually increases towards its end, and the direction of the height is the direction in which the bearing surface faces the face cover.

[0009] In the above embodiments, the water flow flows along the diversion strip towards the drain outlet, so that there is more water flow near the drain outlet. The height of the diversion strip gradually increases towards the end, so that the depth of the diversion channel at the end of the diversion strip is greater than that at other positions, so as to block more water flow and make it difficult for the water flow to cross the diversion strip.

[0010] In at least one embodiment, the water diversion structure further includes a water blocking strip. The water blocking strip is arranged on the bearing surface and located in the diversion channel. An assembly groove is formed between the water blocking strip and the diversion strip, and the assembly groove communicates with the drain outlet; an installation part is arranged on one side of the face cover facing the bearing surface, and the installation part is configured to be installed in the assembly groove to connect the face cover and the outer frame.

[0011] In the above embodiments, by installing the installation part of the face cover in the assembly groove, the assembly of the face cover and the outer frame can be realized. In addition, the water blocking strip can block part of the water flow from flowing towards the diversion strip and initially block the water flow entering the diversion channel from the gap. When the water flow is not much, it can directly flow along the water blocking strip until it flows towards the drain outlet; when the water flow is more, part of the water flow enters the assembly groove and then flows towards the drain outlet.

[0012] In at least one embodiment, a holding part is formed between the outer frame and the face cover. The holding part is located at the end of the diversion strip; the cover body further includes a covering part, the covering part is connected to the face cover and is arranged opposite to the holding part, and a clearance area is formed between the holding part and the covering part.

[0013] In the above embodiments, the setting of the holding part facilitates the user to move the energy storage device, and the clearance area can avoid the user's hand and facilitate holding the holding part.

[0014] In at least one embodiment, there are two ends of the diversion strip, and there are two drain outlets. Each end of the diversion strip corresponds to one drain outlet. The holding part has opposite first end and second end. The first end is connected to the second ring edge at one end of the diversion strip, and the second end is connected to the second ring edge at the other end of the diversion strip.

[0015] In the above embodiments, the accumulated water in the diversion channel can be diverted and flow to the two drain ports, and flow out to the outside through the two drain ports. Through the combined drainage effect of the two drain ports, the drainage efficiency can be improved and the accumulated water on the cover body can be reduced.

[0016] In at least one embodiment, the covering member has a first diversion surface facing the holding portion. The first diversion surface is exposed outside the housing device and forms a clearance area with the holding portion. The holding portion is provided with a liquid leakage channel. One end of the liquid leakage channel communicates with the drain port, and the other end faces the first diversion surface. The first diversion surface is configured to guide the water flow to the outside of the energy storage device.

[0017] In the above embodiments, the water flow at the drain port can enter the liquid leakage channel and flow from the liquid leakage channel to the first diversion surface. The first diversion surface can guide the water flow to the outside of the energy storage device to achieve the drainage of the housing device. In addition, by providing the first diversion surface on the covering member to achieve drainage, the setting of additional drainage structures is reduced, which is convenient for simplifying the structure of the housing device.

[0018] In at least one embodiment, the covering member has a second diversion surface facing the accommodation cavity; the housing device further includes a support member. In the direction of gravity, the support member is disposed on the battery pack of the energy storage device. The support member has a water receiving groove, and the water receiving groove has an opening; the housing is provided with a drainage channel, and the drainage channel communicates with the opening and the outside respectively; the drain port, the second diversion surface, the water receiving groove, the opening and the drainage channel together form a drainage path, and the drainage path is for the water flow at the drain port to flow through under the action of gravity.

[0019] In the above embodiments, the water flow flowing to the drain port flows to the second diversion surface under the action of gravity, and the second diversion surface guides the water flow to the water receiving groove. The water in the water receiving groove can flow out from the opening and enter the drainage channel, and is discharged to the outside through the drainage channel to discharge the accumulated water on the cover body. The setting of the drainage path facilitates the discharge of the accumulated water by its own gravity and improves the convenience of drainage.

[0020] In at least one embodiment, the housing includes a bottom case and a water holding member. The water holding member includes a seat body and a convex platform. The seat body is assembled to the bottom case and forms a drainage gap with the bottom case. The drainage gap extends to the bottom of the bottom case and communicates with the outside; the convex platform is provided with a groove, and the groove communicates with the opening and the drainage gap respectively. The groove and the drainage gap are configured to form a partial drainage channel.

[0021] In the above embodiments, the water flow flowing out from the opening of the water receiving groove can enter the groove, and the water in the groove flows to the outside through the drainage gap. The drainage gap can guide the water flow to the bottom of the bottom case, so that the water flow is not easily in contact with components such as the battery pack in the housing device during the flowing process, reducing the occurrence of safety problems such as short circuits.

[0022] An embodiment of the present application further provides an energy storage device, including a battery pack, an inverter module, and the housing device in any of the above embodiments. The battery pack and the inverter module are disposed in the accommodation cavity.

[0023] In the above energy storage device, the housing device can provide protection for the battery pack and the inverter module. When water accumulates on the housing device, the water flow can be discharged outside the energy storage device through the water diversion structure, so that the inside of the housing device is not easily flooded, and the battery pack and the inverter module are not easily damaged due to water ingress or moisture, improving the waterproof performance of the energy storage device and enhancing the safety of use of the energy storage device.

[0054] Next, the technical solutions in the embodiments of the present application will be described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0056] In the description of this application, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings.

[0057] The upper cover part of the energy storage device is sometimes designed as a split structure for the consideration of industrial design aesthetics. For example, the upper cover is a combined structure of an outer frame and a face cover. There will be a gap between the two split parts. When water accumulates on the top of the energy storage device, water is likely to enter through the gap, thus entering the interior of the energy storage device to erode electrical components or cause electrical components to short-circuit, resulting in potential safety hazards for the energy storage device.

[0058] An embodiment of this application provides a housing device applied to an energy storage device. The housing device includes a cover body and a housing. The cover body includes an outer frame and a face cover. The inner edge of the outer frame is offset from top to bottom to form a first ring edge and a second ring edge. The face cover is disposed within the area enclosed by the first ring edge, and a gap is formed at the junction with the first ring edge. The second ring edge is formed with a water diversion structure. The water diversion structure is arranged along the extending direction of the second ring edge, and a drainage port communicating with the outside is formed at the end of the water diversion structure. The water diversion structure is configured to receive and guide the water flowing down from the gap to the drainage port. The housing and the cover body are snapped together to form a receiving cavity at least for accommodating the battery pack of the energy storage device.

[0059] In the above housing device, when water accumulates on the cover body, the water can flow from the gap to the water diversion structure on the second ring edge. Under the guiding action of the water diversion structure, the water flow can flow to the drainage port and flow to the outside from the drainage port, thereby reducing the water accumulation on the cover body, improving the waterproof performance of the energy storage device, and enhancing the use safety of the energy storage device.

[0060] The following will elaborate on some embodiments of this application with reference to the drawings. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0061] Refer to Figure 1 And Figure 2 , an embodiment of this application provides a housing device 100 and an energy storage device 1000. The energy storage device 1000 includes a housing device 100, a battery pack 200, and an inverter module 300. The battery pack 200 and the inverter module 300 are disposed within the housing device 100. The housing device 100 can provide a protective effect for the battery pack 200 and the inverter module 300.

[0062] In some embodiments, the energy storage device 1000 can be a household or industrial and commercial energy storage power supply, or a portable mobile power supply, etc., for easy use in outdoor places.

[0063] Referring to Figure 1 and Figure 2 , in some embodiments, the housing device 100 includes a cover body 10 and a housing 20. The housing 20 and the cover body 10 are snapped together to form a receiving cavity 400, and the receiving cavity 400 is at least used to receive the battery pack 200. Understandably, the inverter module 300 is also disposed in the receiving cavity 400. The cover body 10 and the housing 20 can isolate the battery pack 200 and the inverter module 300 from the outside world to reduce the risk of water ingress into the battery pack 200 and the inverter module 300. Wherein the "outside world" is the outside of the energy storage device 1000, and the outside world and the receiving cavity 400 are separated by the housing device 100.

[0064] Referring to Figures 2 to 4 , in some embodiments, the cover body 10 includes an outer frame 11 and a face cover 12. The inner edge of the outer frame 11 is formed with a first ring edge 111 and a second ring edge 112 in a stepped manner from top to bottom. The face cover 12 is disposed in the area surrounded by the first ring edge 111, and a gap 30 is formed at the junction with the first ring edge 111. Understandably, the gap 30 at the junction of the face cover 12 and the first ring edge 111 can be formed for design aesthetics, or it can be formed unavoidably after the face cover 12 and the outer frame 11 are assembled due to the split structure of the face cover 12 and the outer frame 11. Wherein the "downward" direction refers to the direction of gravity, which is the Y-axis direction shown in the figure; the "upward" direction is the opposite direction of the gravity direction, which is the X-axis direction shown in the figure. When the energy storage device 1000 is placed normally, the housing 20 is located below the cover body 10 to support the cover body 10.

[0065] The second ring edge 112 is formed with a water diversion structure 113. The water diversion structure 113 is arranged along the extending direction of the second ring edge 112, and a drain port 1131 communicating with the outside world is formed at the end of the water diversion structure 113. The water diversion structure 113 is configured to receive and guide the water flowing down from the gap 30 to the drain port 1131.

[0066] When the cover body 10 is accumulated with water, the water can flow from the gap 30 to the water diversion structure 113 of the second ring edge 112. Under the guiding action of the water diversion structure 113, the water flow can flow to the drain port 1131 and flow from the drain port 1131 to the outside world, thereby reducing the accumulated water on the cover body 10, improving the waterproof performance of the energy storage device 1000, and improving the use safety of the energy storage device 1000.

[0067] Referring to Figures 3 to 5, in some embodiments, the outer frame 11 has a hollowed-out area 114, which is generally located in the middle of the outer frame 11 and within the area enclosed by the first annular edge 111. A gap 30 is formed between the outer edge of the face cover 12 and the first annular edge 111, and the second annular edge 112 encloses the hollowed-out area 114. A part of the face cover 12 completely covers the hollowed-out area 114, and a part covers the second annular edge 112. Specifically, the first annular edge 111 and the second annular edge 112 are generally perpendicular to each other. The first annular edge 111 has an assembly surface 1111 facing the hollowed-out area 114, and a gap 30 is formed between the assembly surface 1111 and the outer edge of the face cover 12; the second annular edge 112 is supported below the face cover 12. The setting of the hollowed-out area 114 can reduce the material used for the outer frame 11 and reduce the weight of the outer frame 11; by covering the hollowed-out area 114 with the face cover 12, it is not easy for external water vapor to enter the accommodation cavity 400 from the hollowed-out area 114.

[0068] Refer to Figures 2 to 5 , in some embodiments, the second annular edge 112 has a bearing surface 1121 facing the face cover 12. The water diversion structure 113 includes a diversion strip 1132, which is arranged on the bearing surface 1121 and along the extending direction of the second annular edge 112. A diversion channel 115 is formed between the diversion strip 1132 and the first annular edge 111, and a drainage port 1131 is formed among the end of the diversion strip 1132, the bearing surface 1121 and the first annular edge 111.

[0069] The accumulated water on the cover body 10 can enter the diversion channel 115 from the gap 30. The diversion channel 115 can accommodate water flow, and the diversion strip 1132 can restrict the water flow from flowing towards the direction away from the first annular edge 111, reducing the risk of water flow entering the internal part of the energy storage device 1000. The water flow in the diversion channel 115 can flow towards the drainage port 1131 along the extending direction of the diversion strip 1132 and be discharged to the outside from the drainage port 1131, thereby realizing the discharge of the accumulated water on the cover body 10. Through the water diversion function of the diversion strip 1132 and the drainage function of the drainage port 1131, the waterproof performance of the energy storage device 1000 is improved, and further the risk of water flow entering the accommodation cavity 400 is reduced, improving the use safety of the energy storage device 1000.

[0070] In some embodiments, towards the direction close to the end of the diversion strip 1132, the bearing surface 1121 gradually inclines away from the face cover 12, that is, the bearing surface 1121 gradually inclines downward. Along the direction of gravity, the face cover 12 is located above the bearing surface 1121. Compared with other positions of the bearing surface 1121, the bearing surface 1121 at the position of the drainage port 1131 close to the end of the diversion strip 1132 is located at a lower position. It can be understood that water can flow downward under the action of gravity, so that the water can flow towards the drainage port 1131 under the action of gravity, which is conducive to the discharge of the water flow from the drainage port 1131 to the outside.

[0071] In some embodiments, the height of the diversion bar 1132 gradually increases in the direction towards its end, and the direction of the height is the direction in which the bearing surface 1121 faces the face cover 12, that is, the X-axis direction in the figure.

[0072] When the water diversion structure 113 drains water, the water flows along the diversion bar 1132 towards the drain port 1131, so that more water accumulates near the drain port 1131, and the water height at this position is likely to increase. The height of the diversion bar 1132 gradually increases towards the end, so that the depth of the diversion channel 115 at the end of the diversion bar 1132 is greater than that at other positions, in order to block more water and prevent the water from easily crossing the diversion bar 1132. The "depth" direction is the direction of gravity, and the "height" direction is the opposite direction of the gravity direction.

[0073] In some embodiments, the second ring edge 112 is provided with a water storage tank (not shown in the figure), and the water storage tank is located in the diversion channel 115. The water storage tank is formed by the bearing surface 1121 being recessed downward. The water storage tank is beneficial for the diversion channel 115 to accommodate more water, reducing the situation where more water entering from the gap 30 cannot be discharged in time, resulting in the water crossing the diversion bar 1132 and entering the accommodation cavity 400 from the hollowed-out area 114.

[0074] Refer to Figures 4 to 7 In some embodiments, the water diversion structure 113 further includes a water blocking bar 1133. The water blocking bar 1133 is disposed on the bearing surface 1121 and is located in the diversion channel 115. The water blocking bar 1133 is located between the assembly surface 1111 and the diversion bar 1132. The outer edge of the face cover 12 is located between the assembly surface 1111 and the water blocking bar 1133. An assembly groove 1134 is formed at an interval between the water blocking bar 1133 and the diversion bar 1132, and the assembly groove 1134 communicates with the drain port 1131; an installation portion 121 is provided on one side of the face cover 12 facing the bearing surface 1121, and the installation portion 121 is configured to be installed in the assembly groove 1134 to connect the face cover 12 and the outer frame 11. Exemplarily, the installation portion 121 is inserted into the assembly groove 1134 in a downward plugging manner and is in interference fit with the assembly groove 1134.

[0075] By installing the installation portion 121 of the face cover 12 in the assembly groove 1134, the assembly of the face cover 12 and the outer frame 11 can be realized. In addition, the water blocking bar 1133 can block part of the water from flowing towards the diversion bar 1132, and preliminarily block the water entering the diversion channel 115 from the gap 30. When the water flow is small, the water can directly flow along the water blocking bar 1133 until it flows to the drain port 1131; when the water flow is large, part of the water enters the assembly groove 1134 and then flows to the drain port 1131.

[0076] Refer to Figure 6 And Figure 7, in some embodiments, the bottom of the assembly groove 1134 is lower than the bearing surface 1121 to increase the depth of the assembly groove 1134, thereby increasing the assembly depth of the installation portion 121 and the assembly groove 1134, and improving the connection stability between the face cover 12 and the outer frame 11.

[0077] Refer to Figure 4 And Figure 5 , in some embodiments, the water blocking strip 1133 is arranged along the extending direction of the diversion strip 1132, and the water blocking strip 1133 is substantially parallel to the diversion strip 1132. The length of the water blocking strip 1133 is less than the length of the diversion strip 1132, and the water blocking strip 1133 does not extend to the end of the diversion strip 1132, so as to facilitate avoiding the drainage port 1131, such that the water blocking strip 1133 is not likely to occupy the space near the drainage port 1131, and it is convenient to increase the drainage speed of the drainage port 1131.

[0078] Refer to Figure 4 And Figure 5 , in some embodiments, the diversion strip 1132 is arranged along the extending direction of a part of the second loop edge 112, so that the diversion strip 1132 does not form a closed loop structure, that is, the diversion strip 1132 has two ends. A drainage port 1131 is correspondingly arranged at each end, so that the water flow entering the diversion channel 115 from the gap 30 can flow through the diversion to the two drainage ports 1131, so as to increase the drainage speed.

[0079] In some embodiments, the height of the diversion strip 1132 is greater than the height of the water blocking strip 1133, such that in the direction from the inner edge of the outer frame 11 towards the center of the hollowed-out area 114, the water flow in the diversion channel 115 can first be blocked by the water blocking strip 1133. When the water flow is too much to be blocked, when the water flow crosses the water blocking strip 1133, the diversion strip 1132 can form a secondary blockage, so that the water flow is not likely to flow towards the hollowed-out area 114.

[0080] Refer to Figure 1 , Figure 3 And Figure 4 , in some embodiments, a holding portion 122 is formed between the outer frame 11 and the face cover 12, and the holding portion 122 is located at the end of the diversion strip 1132; the cover body 10 further includes a covering member 13, the covering member 13 is connected to the face cover 12 and is arranged opposite to the holding portion 122, and a clearance area 40 is formed between the holding portion 122 and the covering member 13. The arrangement of the holding portion 122 facilitates the user to move the energy storage device 1000, and the clearance area 40 can avoid the user's hand, facilitating holding the holding portion 122.

[0081] Refer to Figure 1 , Figure 3 And Figure 4, in some embodiments, the holding portion 122 has opposite first and second ends 1221 and 1222. The first end 1221 is connected to the second loop edge 112 at one end of the diversion strip 1132, and the second end 1222 is connected to the second loop edge 112 at the other end of the diversion strip 1132. It can be understood that the two drain openings 1131 are also oppositely arranged. The accumulated water in the diversion channel 115 can be divided and flow from two directions to the two drain openings 1131, and then flow out to the outside through the two drain openings 1131. Through the combined drainage effect of the two drain openings 1131, the drainage efficiency can be improved and the accumulated water on the cover body 10 can be reduced.

[0082] Refer to Figure 1 , Figure 4 and Figure 6 , in some embodiments, the covering member 13 has a first diversion surface 131 facing the holding portion 122. The first diversion surface 131 is exposed outside the housing device 100 and forms a clearance area 40 with the holding portion 122. The holding portion 122 is provided with a liquid leakage channel 50. One end of the liquid leakage channel 50 communicates with the drain opening 1131, and the other end faces the first diversion surface 131. The first diversion surface 131 is configured to guide the water flow to the outside of the energy storage device 1000.

[0083] The water flow at the drain opening 1131 can enter the liquid leakage channel 50 and flow from the liquid leakage channel 50 to the first diversion surface 131. The first diversion surface 131 can guide the water flow to the outside of the energy storage device 1000 to achieve the drainage of the housing device 100. In addition, by providing the first diversion surface 131 on the covering member 13 to achieve drainage, the setting of additional drainage structures is reduced, which is convenient for simplifying the structure of the housing device 100.

[0084] In some embodiments, the side of the first diversion surface 131 close to the housing 20 is connected to the outer side wall 21 of the housing 20. The first diversion surface 131 is located above the housing 20, and the outer side wall 21 of the housing 20 is connected to the bottom of the housing 20. The water flow on the first diversion surface 131 flows to the outer side wall 21 of the housing 20 under the action of gravity, and then flows along the outer side wall 21 of the housing 20 to the bottom of the housing 20, so as to flow to a support surface such as the ground, realizing the discharge of the accumulated water on the cover body 10 to the outside.

[0085] In some embodiments, the housing device 100 further includes a support member 60. In the direction of gravity, the support member 60 is disposed on the battery pack 200 of the energy storage device 1000. The support member 60 divides the accommodation cavity 400 into two chambers, and one chamber is located above the other chamber. The inverter module 300 is located in the upper chamber, and the battery pack 200 is located in the lower chamber to isolate the inverter module 300 from the battery pack 200, so that the inverter module 300 and the battery pack 200 are not easily affected by each other.

[0086] Refer toFigure 6 and Figures 9 to 12 , in some embodiments, the covering member 13 has a second guiding surface 132 facing the accommodating cavity 400. The supporting member 60 has a water receiving groove 61, and the water receiving groove 61 has an opening 611; the housing 20 is provided with a drainage channel 71, and the drainage channel 71 communicates with the opening 611 and the outside respectively. The drainage port 1131, the second guiding surface 132, the water receiving groove 61, the opening 611, and the drainage channel 71 together form a drainage path 70, and the water flow of the drainage port 1131 flows through the drainage path 70 under the action of gravity. Figure 11 and Figure 12 The dotted lines and the line ends in

[0087] are used to indicate the general directions of the drainage path 70 and the drainage channel 71.

[0088] It can be understood that the second guiding surface 132 and the first guiding surface 131 are two surfaces of the covering member 13 facing away from each other. In the actual structure of the covering member 13, the first guiding surface 131 and the second guiding surface 132 are substantially parallel.

[0088] The water flow flowing to the drainage port 1131 flows to the second guiding surface 132 under the action of gravity, and the second guiding surface 132 guides the water flow to the water receiving groove 61. The water in the water receiving groove 61 can flow out from the opening 611 into the drainage channel 71 and is discharged to the outside through the drainage channel 71, so as to discharge the accumulated water on the cover body 10. The setting of the drainage path 70 facilitates the discharge of the accumulated water by its own gravity and improves the convenience of drainage.

[0089] Refer to Figure 2 and Figures 8 to 10 , in some embodiments, the energy storage device 1000 is generally arranged in a cuboid shape, so that the energy storage device 1000 has four corners, and the water receiving groove 61 corresponding to each drainage port 1131 is located at one of the corners. Along the direction of gravity, the projections of the drainage port 1131, the second guiding surface 132, and the water receiving groove 61 at least partially overlap, and this projection avoids the inverter module 300, so that the water of the drainage port 1131 can flow to the water receiving groove 61 under the action of gravity and the guiding action of the second guiding surface 132 and is not likely to fall onto the inverter module 300.

[0090] It can be understood that the water flow directly falls into the water receiving groove 61 after leaving the second guiding surface 132, and the space for the water flow to fall between the position where the water flow leaves the second guiding surface 132 and the water receiving groove 61 also constitutes a part of the drainage path 70.

[0091] Refer to Figure 2 and Figures 11 to 13, in some embodiments, the housing 20 includes a bottom case 22, a front case 23 and a water-containing member 24. The front case 23 is disposed on one side of the bottom case 22. The front case 23 is provided with a plurality of interfaces 231. The interfaces 231 are electrically connected to the battery pack 200. The interfaces 231 are used to access an external electrical device to supply power to the electrical device, or to access an external power source to charge the energy storage device 1000.

[0092] The water-containing member 24 includes a base body 241 and a boss 242. The base body 241 is assembled to the bottom case 22, and a drainage gap 2411 is formed between the base body 241 and the bottom case 22. The drainage gap 2411 extends to the bottom of the bottom case 22 and communicates with the outside. The boss 242 is provided with a groove 2421. The groove 2421 communicates with the opening 611 and the drainage gap 2411 respectively. The groove 2421 and the drainage gap 2411 are configured to form a partial drainage channel 71.

[0093] The water flowing out of the opening 611 of the water receiving tank 61 can enter the groove 2421. The water in the groove 2421 flows to the outside through the drainage gap 2411. The drainage gap 2411 can guide the water flow to the bottom of the bottom case 22, so that the water flow is not easily in contact with components such as the battery pack 200 in the housing device 100 during the flowing process, and the occurrence of safety problems such as short circuits is reduced.

[0094] It can be understood that the water flow flowing out of the opening 611 of the water receiving tank 61 continues to flow under the action of gravity until it flows into the groove 2421 of the water-containing member 24. The drainage channel 71 further includes a flow path of the water flow from the position where it discharges from the opening 611 of the water receiving tank 61 to the position of the groove 2421 of the water-containing member 24.

[0095] In addition, those of ordinary skill in the art of the present technology should recognize that the above embodiments are only used to illustrate the present application, rather than to limit the present application. As long as it is within the scope of the spirit of the present application, appropriate changes and variations made to the above embodiments fall within the disclosure of the present application.
