SUMMARY

[0003] The utility model aims at solving the problem that waterproof cover in prior art or related art is easily caused by waterlogging for long time and appears waterproof failure.

[0004] In a first aspect, the present application provides an energy storage device, which comprises: a main control box and a water baffle, the water baffle is connected with the main control box, the surface of the water baffle away from the main control box is a water-retaining surface, and the middle region of the water-retaining surface is higher than at least part of the edge region of the water-retaining surface in the direction away from the main control box.

[0005] Since the middle region of the water-retaining surface is higher than at least part of the edge region of the water-retaining surface, the middle region of the water-retaining surface is higher, while at least part of the edge region of the water-retaining surface is lower, and the water on the water-retaining surface will flow from the middle region of the water-retaining surface to the edge region of the water-retaining surface, so that the phenomenon of water storage on the water-retaining surface is not easy to occur, thereby avoiding the problem that the water-retaining surface is soaked by condensate water or external water for long time, preventing the water-retaining surface from being corroded, ensuring that the water-retaining surface can stably play the role of water-retaining for the main control box, and further avoiding the risk that the main control box appears short circuit or performance degradation.

[0006] The bracket supports the box, avoids the box from shaking during use, ensures the installation stability of the box, and thus is beneficial to improving the operation stability of the product.

[0007] In some embodiments, at least part of the water-retaining surface is inclined relative to the main control box, and at least part of the water baffle is protruded from the main control box in the inclined direction of the water-retaining surface.

[0025] In some embodiments, the main control box comprises a box body and a bracket, and the water blocking member is located at one side of the box body along a first direction. The bracket is connected to at least one side of the box body along a second direction, and the first direction intersects the second direction.

DETAILED DESCRIPTION

[0056] In order to enable the above object, features and advantages of the utility model to be more clearly understood, the utility model will be further described below with the drawings and specific embodiments. It should be explained that the embodiments of the application and the features in the embodiments can be combined with each other without conflict.

[0057] In the following description, many specific details are set forth in order to provide a thorough understanding of the utility model, however, the utility model can also be implemented in other ways different from the description herein, therefore, the protection scope of the utility model is not limited by the specific embodiments disclosed below.

[0058] At present, in the tide of the transformation of global energy structure to clean and low-carbon, as the core equipment for balancing energy supply and demand and improving energy utilization efficiency, the importance of energy storage device is increasingly prominent. With the continuous growth of installed capacity of renewable energy such as wind and solar energy, the intermittency, randomness and volatility problems existing in the power generation process pose a serious challenge to the stable operation of power grid, and energy storage device is the key means to solve this contradiction. By storing electric energy when energy is abundant and releasing electric energy when demand is high or power generation is insufficient, the time and space transfer and optimal allocation of energy are realized.

[0059] The main control box is an important component in the energy storage device, and the working environment of the main control box needs to be kept dry. If external water or condensed water contacts the main control box, it may cause short circuit of the main control box, and may also bring the risk of performance degradation of the main control box.

[0060] In related technologies, in order to avoid external water or condensed water contacting the main control box, a water blocking cover is installed on the top of the main control box, which blocks the top of the main control box to prevent external water or condensed water from falling onto the surface of the main control box, thereby reducing the risk of the main control box caused by water contact. However, when water accumulates on the top of the water blocking cover for a long time, the water blocking cover may be corroded, thereby causing the problem of failure of the water blocking cover, resulting in the water blocking cover being unable to effectively block external water or condensed water, and still existing the risk of short circuit or failure of the main control box.

[0061] In addition, after the problem of concave of the water blocking cover occurs, even if the water blocking cover itself is not corroded, the water blocking cover is concave in the middle, and after the upper surface of the water blocking cover is full of water, the water will flow out along the edge of the water blocking cover, and part of the water will slide down to the lowest part of the lower surface of the water blocking cover and then drop, which is just located on the main control box, resulting in the risk of short circuit or failure of the main control box caused by water contact.

[0062] Based on the above consideration, in order to reduce the risk of short circuit or failure of the main control box and make the operating environment of the main control box safer, the present application provides an energy storage device, in which a water blocking member is arranged on the top of the main control box, the water blocking member has a shape that the middle part is higher than at least a part of the edge, external water or condensed water can quickly slide down along the water blocking member, water accumulation on the top of the water blocking member is avoided, and the waterproof function of the water blocking member is prevented from failing.

[0063] Energy storage devices can be used in energy storage power stations, wind power generation systems, solar power generation systems, mobile power systems, or temporary power supply systems. Energy storage power stations can store electrical energy during off-peak hours and provide power to users or electrical equipment during peak hours. Wind power generation systems collect wind energy from wind turbines, convert it into electricity, and then store it in energy storage devices. Solar power generation systems convert solar energy into electricity, store it in energy storage devices, and supply it to users as needed. Mobile power systems can supply power to electrical equipment in areas inaccessible by the mains grid, such as remote mountainous areas and isolated wilderness areas. Temporary power supply systems can provide power to users when there is insufficient electricity.

[0064] Energy storage devices can be energy storage containers, energy storage cabinets, etc.

[0065] In the embodiments of this application, an energy storage device, an energy storage system, and a charging network are proposed.

[0066] Figure 13 This is a schematic diagram of the structure of the charging network 30 provided in some embodiments of this application. Figure 15 This is a schematic diagram of the structure of an energy storage device 10 provided in some embodiments of this application. Embodiments of this application provide a charging network 30, which includes a charging pile 310 for charging electrical equipment. The charging network 30 may also include an energy storage device 10, which is electrically connected to the charging pile 310 and provides electrical energy to the charging pile 310.

[0067] It should be noted that the charging pile 310 is electrically connected to the battery cells in the energy storage device 10 via cables, and the battery cells can supply the charging pile 310 with their stored electrical energy. The charging pile 310 has a connector that can be connected to electrical equipment, thereby replenishing the equipment's power. The application of the energy storage device 10 in this charging network 30 can effectively improve the safety of the charging network 30 and also help to improve the flexibility of the charging network 30 during deployment.

[0068] In a charging network 30, there can be one charging pile 310, and the energy storage device 10 provides power to the one charging pile 310. There can also be multiple charging piles 310, and the energy storage device 10 provides power to multiple charging piles 310.

[0069] As an example, such as Figure 13 As shown, the charging network 30 includes an energy storage device 10 and two charging piles 310, with the energy storage device 10 providing power to the two charging piles 310.

[0070] The energy storage device 10 can include a battery device 150, which is electrically connected with the charging pile 310, so as to provide the charging pile 310 with electric energy.

[0071] Figure 14 A structural schematic diagram of the energy storage system 20 is provided for some embodiments of the present application. The embodiments of the present application provide an energy storage system 20. The energy storage system 20 includes an energy storage converter 210, which can be electrically connected with a power generation device 40, so as to convert the electric power provided by the power generation device 40. The energy storage system 20 can further include an energy storage device 10, which is electrically connected with the energy storage converter 210, and the energy storage converter 210 guides the electric energy provided by the power generation device 40 to the energy storage device 10 after power conversion for storage.

[0072] The power conversion device is used to be connected between the power generation device 40 and the energy storage device 10. The power generation device 40 is used to generate electric energy, and the power generation device 40 is used to store the electric energy generated by the power generation device 40 to the energy storage device 10 through the power conversion device. The energy storage system 20 can effectively improve the operation safety of the energy storage system 20 by applying the energy storage device 10. In specific implementation, the power generation device can be a solar panel, a hydroelectric power generation device, a thermal power generation device, etc. The specific type of the power generation device is not limited in the present application.

[0073] As shown in FIG. 1, Figure 14 The energy storage system 20 includes the energy storage device 10 and the energy storage converter 210, and two power generation devices 40 respectively transmit the electric energy generated to the energy storage converter 210, and the electric energy is guided to the energy storage device 10 through the energy storage converter 210 for storage.

[0074] Please refer to FIG. 2, Figure 15 The energy storage device 10 includes an electric box 150, a main control box 110 and a water blocking member 120. The electric box 150 will generate heat during charging and discharging, and therefore a lot of condensed water will drop from the bottom of the electric box 150. The water blocking member 120 is arranged on the top of the main control box 110, and the water blocking member 120 blocks the condensed water dropped from the bottom of the electric box 150. Figure 16 The relative positions of the unit compartment 160 and the electrical compartment 170 in the energy storage device 10 are shown in FIG. 3.

[0075] In combination with Figure 1 , Figure 7 and Figure 8As shown, the energy storage device 10 comprises a main control box 110 and a water blocking member 120, the water blocking member 120 is connected with the main control box 110, the surface of the water blocking member 120 away from the main control box 110 is a water blocking surface 121, and in the direction away from the main control box 110, the middle region of the water blocking surface 121 is higher than at least a part of the edge region of the water blocking surface 121. The main control box 110 comprises a box body 111 and a bracket 112, and the water blocking member 120 is located on one side of the box body 111 along a first direction (the direction of the arrow H1). Figure 7 The bracket 112 is connected to at least one side of the box body 111 along a second direction (the direction of the arrow H2), and the first direction intersects the second direction. Figure 7

[0076] The main control box 110 is the "nerve center" that undertakes the core control, monitoring and management functions, responsible for overall operation logic of the energy storage system, to ensure that the device safely, efficiently and stably plays the role of energy storage and release. The design of the main control box 110 directly affects the reliability, response speed and intelligent level of the energy storage device 10, and its performance optimization needs to consider data processing capacity, anti-interference ability, environmental adaptability such as high and low temperature, humidity tolerance and long-term operation stability, which is the key component for the energy storage device 10 to realize precise control and safe operation.

[0077] The water blocking member 120 is installed on the top of the main control box 110, and the water blocking member 120 is used to prevent water from entering the main control box 110. The surface of the water blocking member 120 away from the main control box 110 is a water blocking surface 121, which is the top surface of the water blocking member 120. The middle region of the water blocking surface 121 is higher than at least a part of the edge region of the water blocking surface 121. The middle region of the water blocking surface 121 refers to the other region of the water blocking surface 121 except the edge region. Because the middle region of the water blocking surface 121 is higher than at least a part of the edge region of the water blocking surface 121, the middle region of the water blocking surface 121 is higher, while at least a part of the edge region of the water blocking surface 121 is lower. The water on the water blocking surface 121 will flow from the middle region of the water blocking surface 121 to the edge region of the water blocking surface 121, and it is not easy for water to accumulate on the water blocking surface 121.

[0078] By setting the structure of the water blocking surface 121 as the above form, the water blocking member 120 is not easy to have a concave middle, avoiding the problem of condensate water or external water soaking the water blocking member for a long time, preventing the water blocking member 120 from being corroded, and ensuring that the water blocking member 120 can stably prevent water from entering the main control box 110, thereby avoiding the risk of short circuit or performance degradation of the main control box 110.

[0079] Moreover, because the middle region of the water blocking surface 121 is higher than at least a part of the edge region of the water blocking surface 121, water will not flow to the lower surface of the water blocking member 120, further avoiding the risk of use caused by the contact of the main control box 110 with water. ​

[0080] The water blocking member 120 is located on one side of the box body 111 in the first direction, and in a normal use state, the water blocking member 120 is generally located on the top of the box body 111, that is, the first direction is a direction from bottom to top.

[0081] The bracket 112 is arranged on at least one side of the box body 111 in the second direction, and the first direction intersects the second direction, which means that the first direction and the second direction are different directions. The bracket 112 supports the box body 111 to avoid shaking of the box body 111 during use. In the embodiment, the bracket 112 is located on the side of the box body 111.

[0082] The first direction intersects the second direction means that the first direction and the second direction can be arranged perpendicularly, or can be arranged non-perpendicularly by only intersecting, that is, arranged by intersecting at an acute angle or an obtuse angle, for example, the first direction and the second direction can be arranged at an angle of 30°, 60°, 80°, 120°, 150° or 170°.

[0083] As shown in Figure 1 , Figure 7 and Figure 8 , in some embodiments, at least part of the water blocking surface 121 is arranged obliquely relative to the main control box 110, and at least part of the water blocking member 120 protrudes from the main control box 110 along the oblique direction of the water blocking surface 121.

[0084] At least part of the water blocking surface 121 is an inclined surface, and water falling on the surface of the water blocking surface 121 can flow along the oblique direction of the water blocking surface 121, so that the water on the water blocking surface 121 can flow to the edge of the water blocking member 120.

[0085] At least part of the water blocking member 120 protrudes from the main control box 110 along the oblique direction of the water blocking surface 121, that is, at least part of the water blocking member 120 protrudes from the main control box 110 along the oblique direction of the water blocking surface 121.

[0086] When the water on the water blocking member 120 drips from the edge of the water blocking member 120, the water on the water blocking member 120 does not contact the main control box 110, avoiding the problem of short circuit or performance degradation of the main control box 110 due to contact with water, and being beneficial to improve the waterproof effect of the water blocking member 120 on the main control box 110.

[0087] As shown in Figure 1 , Figure 7 and Figure 8 , in some embodiments, the water blocking surface 121 includes a first inclined surface 122 and a second inclined surface 123, and the first inclined surface 122 is inclined away from the main control box 110 along a direction close to the second inclined surface 123, and the second inclined surface 123 is inclined away from the main control box 110 along a direction close to the first inclined surface 122.

[0088] The water-blocking surface 121 can be composed of a first inclined surface 122 and a second inclined surface 123. One side of the first inclined surface 122 is connected to one side of the second inclined surface 123. The first inclined surface 122 is inclined in a direction away from the main control box 110. The second inclined surface 123 is inclined in a direction away from the main control box 110. The second inclined surface 123 is inclined in a direction away from the main control box 110.

[0089] From the side of the first inclined surface 122 away from the second inclined surface 123 to the side of the second inclined surface 123 away from the first inclined surface 122, the water-blocking surface 121 first tilts away from the main control box 110, and then tilts towards the main control box 110. The water-blocking surface 121 has a structure that is high in the middle and low on both sides. Water dripping onto the water-blocking surface 121 can flow along the first inclined surface 122 or the second inclined surface 123, avoiding water accumulation on the water-blocking surface 121, which helps to improve the waterproof effect of the water-blocking component 120.

[0090] In some embodiments, the first inclined surface 122 is a plane or a curved surface; and / or, the second inclined surface 123 is a plane or a curved surface.

[0091] Combination Figure 1 and Figure 7 As shown, both the first inclined surface 122 and the second inclined surface 123 are planar. In this case, the structure of the first inclined surface 122 and the second inclined surface 123 is easy to process, and the first inclined surface 122 and the second inclined surface 123 can also play a good waterproof role.

[0092] Or, such as Figure 2 As shown, both the first inclined surface 122 and the second inclined surface 123 are curved surfaces, that is, Figure 2 The first curved surface 124 and the second curved surface 125 are in this case. The edges of the first inclined surface 122 and the second inclined surface 123 have a large slope. This structure is conducive to the rapid dripping of water on the water-blocking surface 121 and prevents water from adhering to the bottom of the water-blocking member 120 under tension.

[0093] Alternatively, the first inclined surface 122 can be a plane, and the second inclined surface 123 can be a curved surface.

[0094] Of course, in other embodiments, the water-blocking surface 121 can also be Figure 3 and Figure 4 The arc-shaped surface 126 shown in the figure means that the water-blocking surface 121 does not need to be divided into two segments, but the water-blocking surface 121 is a uniformly transitioned arc-shaped structure.

[0095] Alternatively, the water-blocking surface 121 can also be a Figure 5 and Figure 6 The spherical cap 127 is a part of a spherical surface.

[0096] As shown in Figure 1 , Figure 7 and Figure 8 In some embodiments, the water-blocking member 120 includes a first water-blocking plate 128 and a second water-blocking plate 129, the second water-blocking plate 129 is connected with the first water-blocking plate 128, and the first water-blocking plate 128 is inclined away from the main control box 110 in a direction close to the second water-blocking plate 129. The second water-blocking plate 129 is inclined away from the main control box 110 in a direction close to the first water-blocking plate 128.

[0097] In the above embodiments, the top surface of the water-blocking member 120 is defined as the water-blocking surface 121, and the water-blocking surface 121 is inclined relative to the main control box 110, so that the middle region of the water-blocking member 120 is higher than at least a part of the edge region. In this case, the water-blocking member 120 can not be an inclined structure, i.e., the water-blocking member 120 is not arranged in an inclined form relative to the main control box 110, but only the top surface of the water-blocking member 120 is arranged in an inclined structure.

[0098] In the present embodiment, the water-blocking member 120 includes the first water-blocking plate 128 and the second water-blocking plate 129, and both the first water-blocking plate 128 and the second water-blocking plate 129 are inclined relative to the main control box 110. Moreover, the inclination direction of the first water-blocking plate 128 is the same as that of the first inclined surface 122, and the inclination direction of the second water-blocking plate 129 is the same as that of the second inclined surface 123.

[0099] Since the first water-blocking plate 128 and the second water-blocking plate 129 are integrally inclined structures, the top surface of the first water-blocking plate 128 and the second water-blocking plate 129 do not need to be machined separately, thereby reducing the machining difficulty of the first water-blocking plate 128 and the second water-blocking plate 129.

[0100] The first water-blocking plate 128 and the second water-blocking plate 129 can both be flat plate structures, or the first water-blocking plate 128 and the second water-blocking plate 129 can both be curved structures, or the first water-blocking plate 128 is a flat plate structure and the second water-blocking plate 129 is a curved structure.

[0101] When the water-blocking surface 121 is an arc-shaped surface 126 or a spherical cap 127, the water-blocking member 120 can also be machined into a corresponding structure.

[0102] In some embodiments, the water-blocking member 120 is made of plastic.

[0103] The water blocking piece 120 can be made of plastic material, which has the advantage of light weight. The light weight of the water blocking piece 120 can reduce the pressure borne by the main control box 110, thereby avoiding damage to the main control box 110 caused by the water blocking piece 120.

[0104] The water blocking piece 120 also has the advantage of low material cost, thereby facilitating the reduction of the processing cost of the water blocking piece 120.

[0105] If the water blocking piece 120 is made of metal material, the surface of the water blocking piece 120 made of metal material is prone to accumulate condensed water, thereby requiring additional pasting of anti-condensation felt on the surface of the water blocking piece 120. In the embodiment, the water blocking piece 120 is made of plastic material, and the surface of the water blocking piece 120 made of plastic material is not prone to accumulate condensed water, without the need for pasting of anti-condensation felt, thereby further reducing the cost of the water blocking piece 120.

[0106] Of course, the water blocking piece 120 can also be made of metal material, for example, the water blocking piece 120 is made of aluminum material.

[0107] In combination with FIGS. 1 and 2, Figure 1 and Figure 10 In some embodiments, the energy storage device 10 further includes a support piece 130 connected between the main control box 110 and the water blocking piece 120, or the water blocking piece 120 abuts against the main control box 110.

[0108] The support piece 130 can be installed between the main control box 110 and the water blocking piece 120, and the support piece 130 plays a supporting role on the water blocking piece 120, thereby avoiding deformation of the water blocking piece 120.

[0109] The supporting role of the support piece 130 is conducive to improving the structural stability of the water blocking piece 120, and ensuring that the water blocking piece 120 can stably play a water blocking role on the main control box 110.

[0110] The shape of the support piece 130 is the same as that of the water blocking piece 120, that is, the support piece 130 can also be provided in an inclined structure. The shape of the support piece 130 is adapted to the shape of the water blocking piece 120, so that the support piece 130 is attached to the bottom of the water blocking piece 120, thereby facilitating the supporting effect of the support piece 130 on the water blocking piece 120.

[0111] Of course, the support piece 130 can also be directly supported by the main control box 110 without being provided between the main control box 110 and the water blocking piece 120.

[0112] In combination with FIGS. 1 and 2, Figure 1 and Figure 10 In some embodiments, the energy storage device 10 further includes a buffer piece 140 located between the water blocking piece 120 and the support piece 130.

[0113] In the process of transporting the energy storage device 10, a collision between the water-blocking member 120 and the support member 130 can generate a large noise, and in the case of frequent vibration of the water-blocking member 120 and the support member 130, the water-blocking member 120 or the support member 130 can be damaged.

[0114] In the embodiment, the buffer member 140 can be installed between the water-blocking member 120 and the support member 130, and the buffer member 140 can buffer the water-blocking member 120 and the support member 130, so as to avoid vibration and noise generated by the collision between the water-blocking member 120 and the support member 130, and to reduce the damage rate of the water-blocking member 120 and the support member 130.

[0115] The buffer member 140 can be made of a soft material, for example, the buffer member 140 can be made of rubber, foam or silica gel.

[0116] In some embodiments, the water-blocking member 120 is detachably connected to the support member 130.

[0117] The water-blocking member 120 can be detachably connected to the support member 130, that is, the water-blocking member 120 and the support member 130 are a split structure, and the water-blocking member 120 and the support member 130 can be processed respectively, and then installed.

[0118] The above-described arrangement of the water-blocking member 120 and the support member 130 can reduce the processing difficulty of the water-blocking member 120 and the support member 130. Moreover, when the water-blocking member 120 or the support member 130 is damaged, the damaged part can be replaced separately, thereby reducing the maintenance cost of the energy storage device 10.

[0119] In some embodiments, the number of support members 130 is multiple, and adjacent two support members 130 are spaced apart.

[0120] A plurality of support members 130 are installed at the bottom of the water-blocking member 120, and the plurality of support members 130 simultaneously support the water-blocking member 120, and in the case of spaced arrangement of adjacent two support members 130, it is indicated that the plurality of support members 130 support part of the bottom of the water-blocking member 120. This arrangement can reduce the material consumption of the support member 130, thereby reducing the overall weight of the support member 130, and further reducing the pressure borne by the main control box 110.

[0121] Of course, in other embodiments, the support member 130 can also be a whole plate structure, and the support member 130 supports the entire bottom surface of the water-blocking member 120.

[0122] In combination with Figure 1 , Figure 7 , Figure 8 and Figure 11As shown in some embodiments, the box 111 is provided with a mounting portion 113 on at least one side in the second direction, and the bracket 112 is provided with a bearing surface 114 for bearing the mounting portion 113. The bearing surface 114 is provided with a first limiting portion 115 and a second limiting portion 116, and the mounting portion 113 is located between the first limiting portion 115 and the box 111, and a part of the mounting portion 113 is inserted between the second limiting portion 116 and the bearing surface 114.

[0123] The box 111 is provided with a mounting portion 113 on at least one side in the second direction, and the box 111 is fixed to the bracket 112 through the mounting portion 113.

[0124] The bearing surface 114 in the bracket 112 is used to bear the mounting portion 113, that is, the bearing surface 114 supports the mounting portion 113.

[0125] The bearing surface 114 is provided with a first limiting portion 115 and a second limiting portion 116, and a part of the mounting portion 113 is located between the first limiting portion 115 and the box 111 during the installation of the mounting portion 113. The first limiting portion 115 limits the mounting portion 113, and the first limiting portion 115 can prevent the mounting portion 113 from moving in the second direction.

[0126] A part of the mounting portion 113 is also located between the second limiting portion 116 and the bearing surface 114, and the second limiting portion 116 can limit the mounting portion 113 from being raised upward relative to the bearing surface 114, thereby preventing the mounting portion 113 from being separated from the bearing surface 114.

[0127] The first limiting portion 115 and the second limiting portion 116 limit the mounting portion 113 in different directions, which is beneficial to improve the connection stability of the mounting portion 113 and the bracket 112. Moreover, this installation method can conveniently install the mounting portion 113 on the bracket 112, and improve the assembly convenience of the energy storage device 10.

[0128] In the embodiment, the box 111 is provided with mounting portions 113 and brackets 112 on both sides, of course, in other embodiments, more mounting portions 113 and brackets 112 can be provided around the box 111.

[0129] As shown in Figure 1 , Figure 7 , Figure 8 , Figure 11 and Figure 12 , in some embodiments, the first limiting portion 115 is provided with a guide bending portion 117 on one side, and the guide bending portion 117 is used to guide the mounting portion 113 between the first limiting portion 115 and the box 111.

[0130] During the installation of the mounting portion 113, the mounting portion 113 needs to be inserted between the first limiting portion 115 and the box body 111, and the position of the mounting portion 113 needs to be frequently adjusted to ensure that the mounting portion 113 is aligned with the gap between the first limiting portion 115 and the box body 111, which brings certain difficulty to the installation of the mounting portion 113.

[0131] In the embodiment, the guide bending portion 117 is arranged on one side of the first limiting portion 115, and the guide bending portion 117 plays a guiding role for the mounting portion 113. Under the guiding role of the guide bending portion 117, the mounting portion 113 can be smoothly inserted between the first limiting portion 115 and the box body 111, and the installation position of the mounting portion 113 does not need to be frequently adjusted, thereby providing convenience for the installation process of the mounting portion 113.

[0132] For example, the guide bending portion 117 is bent away from the box body 111, and when the mounting portion 113 contacts the guide bending portion 117, the mounting portion 113 can slide along the guide bending portion 117, and the end portion of the mounting portion 113 can slide between the first limiting portion 115 and the box body 111 under the guiding role of the guide bending portion 117.

[0133] In some embodiments, the first limiting portion 115 is integrally formed on the bracket 112, or the first limiting portion 115 and the bracket 112 are in a split structure, and / or the second limiting portion 116 is integrally formed on the bracket 112, or the second limiting portion 116 and the bracket 112 are in a split structure.

[0134] The first limiting portion 115 and the bracket 112 can be in an integrated structure, for example, the bracket 112 and the first limiting portion 115 are integrally processed when the bracket 112 is processed. Alternatively, after the bracket 112 is processed, a part of the bracket 112 is bent to form the first limiting portion 115 on the bracket 112.

[0135] The first limiting portion 115 and the bracket 112 can also be in a split structure, that is, the first limiting portion 115 and the bracket 112 are respectively processed, and then the first limiting portion 115 is welded and fixed on the bracket 112, or the first limiting portion 115 is fixed on the bracket 112 by using a screw or other locking structure.

[0136] Similarly, the second limiting portion 116 and the bracket 112 can be in an integrated structure, for example, the bracket 112 and the second limiting portion 116 are integrally processed when the bracket 112 is processed. Alternatively, after the bracket 112 is processed, a part of the bracket 112 is bent to form the second limiting portion 116 on the bracket 112.

[0137] The second limiting part 116 and the bracket 112 can also be a split structure, that is, the second limiting part 116 is welded to the bracket 112 or fixed to the bracket 112 by using a screw locking structure after the second limiting part 116 and the bracket 112 are respectively machined.

[0138] The machining of the first limiting part 115 and the second limiting part 116 is flexible, so that the first limiting part 115 and the second limiting part 116 can be machined according to actual conditions.

[0139] In combination with Figure 1 , Figure 7 , Figure 8 and Figure 11 , in some embodiments, the mounting part 113 is provided with a third limiting part 118 at an end away from the second limiting part 116, an included angle is formed between the third limiting part 118 and the mounting part 113, and the third limiting part 118 is locked to a side of the bracket 112.

[0140] When the mounting part 113 is mounted, one end of the mounting part 113 is inserted between the second limiting part 116 and the supporting surface 114, but if the mounting part 113 is not further fixed, the mounting part 113 can move relative to the bracket 112, causing the mounting part 113 to be separated from the second limiting part 116, and further causing the problem that the second limiting part 116 cannot limit the mounting part 113.

[0141] In the embodiment, the third limiting part 118 is provided at an end of the mounting part 113 away from the second limiting part 116, the third limiting part 118 is bent relative to the mounting part 113, and the third limiting part 118 is fixed to a side of the bracket 112.

[0142] Since the third limiting part 118 is locked to the side of the bracket 112, the third limiting part 118 limits the movement of the mounting part 113 relative to the bracket 112, thereby avoiding the separation of the mounting part 113 from the second limiting part 116 and ensuring that the second limiting part 116 can stably limit the mounting part 113.

[0143] In related technologies, the water baffle has a high weight, which reduces the system mass energy density. The water baffle is inclined in the Y direction, the main control box 110 has a long length, and the same slope angle occupies a large height in the Z direction. As the energy density of the energy storage container becomes higher and higher, the space in each direction is very important. The metal sheet is used to make the water baffle, and the metal sheet bottom needs to be additionally provided with a condensation prevention felt, which increases the cost.

[0144] The structural defects in the related art cause water accumulation in the water shield, and the middle of the traditional sheet metal water shield is prone to sagging, causing condensate water or external water droplets to accumulate inside the water shield. Long-term soaking can cause corrosion problems, and in severe cases, it can cause the main control box cover to corrode, thereby affecting the normal operation of the electrical equipment and control system, and there is a risk of short circuit or performance degradation.

[0145] Condensed water accumulates on the upper part of the water shield, and after the water shield is corroded away by long-term soaking, water droplets fall onto the main control box. In addition, in the case of sagging of the water shield, even if the water shield itself is not corroded, but the middle of the water shield sags, after the upper surface of the water shield is full of water, the water will overflow along the edge of the water shield, and part of the water will slide down the lower surface of the water shield to the lowest point of the lower surface of the water shield and then fall. This is just above the main control box. When water droplets fall onto the main control box, the main control box cover can be corroded, or water can spread along the main control box cover to the external wiring connector of the main control box, posing a risk of short circuit of electrical equipment.

[0146] Defects of excessive weight: The density of sheet metal material is relatively high, resulting in a relatively large overall weight of the water shield, increasing the burden of the main control box 110, especially in a main control box 110 with a heavy weight, this problem is more prominent.

[0147] Defects of high cost of condensate water treatment: To prevent condensate water accumulation, the traditional scheme usually needs to additionally paste a condensation-proof felt, increasing the manufacturing cost and maintenance cost.

[0148] The scheme in the present embodiment:

[0149] The middle of the water shield is convex, which can prevent the water shield from sagging and effectively solve the problem of water accumulation in the middle of the traditional sheet metal water shield.

[0150] The sheet metal scheme is changed to a plastic water shield, reducing weight and cost.

[0151] After the water shield 120 is made of plastic material, there is no need to paste a condensation-proof felt, further reducing the cost.

[0152] The convex structure of the water shield 120 improves the drainage efficiency.

[0153] The convex design in the middle of the water shield 120 effectively prevents water accumulation and avoids the corrosion problem caused by the sagging of the middle of the traditional sheet metal water shield, prolongs the service life of the water shield 120, and improves the protection performance.

[0154] The water shield 120 made of plastic material significantly reduces the weight and manufacturing cost.

[0155] After the water shield 120 is made of plastic material, there is no need to additionally paste a condensation-proof felt, reducing the maintenance cost.

[0156] The middle of the water shield 120 is convex, preventing water droplets from accumulating.

[0157] In the embodiments of the present application, the water blocking part 120 is fixed with the support part 130 having an upper convex structure through a plastic buckle. The middle of the support part 130 is designed as an upper convex structure, which effectively prevents the water blocking part 120 from being concave and accumulating water. The shape of the upper convex structure of the support part 130 is optimized and designed to ensure good cooperation with the drainage groove of the water blocking part 120, thereby improving the drainage efficiency. The fixing mode of the water blocking part 120 and the support part 130 is not limited, and the number of fixing structures is not limited. The buckle, plastic rivet or pull rivet connection mode can be used, so as to facilitate installation and disassembly. The selection of the connection mode takes into account convenience and reliability, and ensures that the water blocking part 120 will not loosen during use. The support part 130 and the water blocking part 120 can also be provided with a foam pad in the middle, which can prevent vibration during transportation and is conducive to reducing noise. The water blocking part 120 can also be provided with an upper convex structure matching the upper convex structure of the support part 130, so as to ensure that water droplets can be quickly drained and prevent water droplets from accumulating inside the water blocking part 120. The material of the water blocking part 120 is not limited, for example, the water blocking part 120 can be made of plastic material, which has the advantages of light weight, corrosion resistance and good mechanical properties. The water blocking part 120 can also be made of metal material. The support part 130 and the bracket 112 are fixed by using a draw core rivet, and the specific fixing form can also be not limited, which can also be in the form of welding / plastic buckle, etc.

[0158] The main control box 110 is supported by the supporting surface 114 of the bracket 112. The head of the first limiting part 115 has a guide bending structure, which is convenient for the main control box 110 to enter along the Y direction. In the embodiments, the number of the first limiting part 115 is two, and the two first limiting parts 115 can limit the main control box 110 along the X direction. The second limiting part 116 can be pressed on the corresponding installation interface of the main control box 110 to limit the Z direction. The structure of the first limiting part 115 and the second limiting part 116 is not limited in form, and the number is also not limited. It can be a structure bent out of the bracket 112, or it can be a post-welding structure.

[0159] When the third limiting part 118 contacts the side of the bracket 112, the side of the bracket 112 limits the installation part 113 in the Y direction. Through the above structure, the main control box 110 is limited in X / Y / Z three directions respectively, and finally the bolt locking is completed to install the main control box 110.

[0160] In the embodiments, through the cooperation of the water blocking part 120 and the upper convex structure of the support part 130, it is ensured that the top of the water blocking part 120 is free of water accumulation, and the corrosion problem caused by long-term immersion of the main control box 110 or other devices is avoided.

[0161] The structure design of the bracket 112 in the embodiments not only facilitates the installation of the main control box 110, but also can be limited, thereby avoiding the risk problem caused by displacement during transportation and operation.
