The liquid-cooled heat dissipation component is used to dissipate heat from the energy storage units. The control components can be located inside the door panel and are used to monitor the system's operating status. The protective cover covers the control components and prevents condensation on the surface of the liquid-cooled heat dissipation component from coming into contact with the control components.

[0004] However, in the above structure, the protective cover and the door panel are usually connected by bolts, which makes it difficult to disassemble and assemble the protective cover, resulting in low maintenance efficiency of the control components. Utility Model Content

[0050] Currently, liquid-cooled energy storage systems are common outdoor energy storage systems. A typical liquid-cooled energy storage system includes a housing, door panel, control components, energy storage units, liquid cooling heat dissipation components, and a protective cover. The door panel is usually installed perpendicular to the ground and rotatably connected to the housing, and can be opened or closed relative to the housing. The energy storage units and liquid cooling heat dissipation components are both located inside the housing; the liquid cooling heat dissipation components are used to cool the energy storage units. The control components may be located inside the door panel and are electrically connected to both the energy storage units and the liquid cooling heat dissipation components. The control components are used to monitor the system's operating status. The protective cover covers the control components to prevent condensation on the surface of the liquid cooling heat dissipation components from contacting the control components. When the energy storage unit and / or liquid cooling heat dissipation components fail, maintenance personnel typically need to open the door panel, remove the protective cover from the door panel, and then determine the location of the fault based on the monitoring data displayed by the control components. When the control components fail, maintenance personnel also need to remove the protective cover from the door panel and then replace the control components. However, in the above structure, the protective cover and the door panel are usually connected by bolts, which makes it difficult to disassemble and assemble the protective cover, resulting in low maintenance efficiency of the liquid-cooled energy storage system.

[0051] To address the aforementioned problems, this disclosure provides a protective shield assembly, such as... Figure 1 As shown, the protective cover assembly includes a plate 100, a connector 1, and a cover 2.

[0052] Among them, plate 100 is a component used to install connector 1. Plate 100 can be the wall panel of the liquid-cooled energy storage system box or the plate of the liquid-cooled energy storage system.

[0053] Connector 1 is a component in the protective cover assembly that provides installation space for the cover 2. In some examples, the panel 100 is the door panel of a liquid-cooled energy storage system, and connector 1 is located on the inner side of the door panel, that is, near the housing. Figure 1 (Not shown) On one side inside, and the connector 1 is fixedly connected to the plate 100.

[0054] Among them, the cover 2 is a component in the protective cover assembly used for the cover control assembly 200, see [link / reference] Figure 2 The control component 200 includes the wiring side of EMS (Energy Management System), indicator lights and emergency stop button. The cover 2 is snapped into the aforementioned connector 1. The cover 2 and the plate 100 enclose a receiving space for accommodating the control component 200.

[0055] Using the technical solution provided in this embodiment, in the protective cover assembly, the cover 2 and the plate 100 house the control component 200. The cover 2 and the plate 100 are connected by a connector 1, rather than by bolts. This allows maintenance personnel to quickly and easily disassemble and reassemble the cover 2 and the plate 100 when the control component, energy storage unit, and / or liquid cooling heat dissipation component fail, thereby improving the maintenance efficiency of the liquid-cooled energy storage system.

[0056] For example, both the connector 1 and the cover 2 can be made of stainless steel, such as SPCC (Steel Plate Cold Commercial, generally made of cold-rolled carbon steel sheet and strip). The connection between the connector 1 and the plate 100 can be welding or bolted.

[0057] See in some examples Figure 2 The plate 100 has a receiving groove 1001 on the side near the cover 2. The receiving groove 1001 is used to receive at least a portion of the control component 200. The cover 2 covers the opening of the receiving groove 1001. The groove wall of the receiving groove 1001, the portion of the wall of the plate 100 near the cover 2, and the cover 2 enclose the aforementioned receiving space, and the control component 200 is located in the receiving space.

[0058] In some examples, the thickness of the cover 2 can be within the range of [0.3mm, 1.3mm], and the thickness of the connector 1 can be within the range of [0.5mm, 1.5mm]. That is, the thickness of the SPCC plate used to make the cover 2 can be within the range of [0.3mm, 1.3mm], and the thickness of the SPCC plate used to make the connector 1 can be within the range of [0.5mm, 1.5mm].

[0059] For example, the thickness of connector 1 can be 1.0 mm, and the thickness of cover 2 can be 0.8 mm.

[0060] In some possible implementations, the cover 2 includes a cover body 21 and a flange 22.

[0061] like Figure 3 As shown, the cover body 21 has a hollow cubic structure with an opening on one side. The cover body 2 includes multiple flanges 22, which are located on different walls of the cover body 21 and are connected to the cover body 21 respectively. The flanges 22 are engaged with the connectors 1.

[0062] In some examples, connector 1 includes multiple connecting plates 11 that snap into flange 22. See specifically... Figure 4 and Figure 5 ( Figure 5 for Figure 4(In the cross-sectional view along the AA direction), the connecting plate 11 includes a connecting part 111 and a limiting part 112. The connecting part 111 is connected to the plate body 100, and the limiting part 112 is connected to the connecting part 111 and is arranged at intervals from the plate body 100.

[0063] Furthermore, the limiting part 112 and the plate 100 can be arranged in parallel.

[0064] In implementation, the gap 110 between the limiting part 112 and the plate 100 accommodates the flange 22, and the wall surface of the limiting part 112 near the plate 100 can abut against the flange 22, thereby limiting the flange 22 in a direction perpendicular to the plate 100. That is, a single connecting plate 11 can engage the cover 2 in a direction perpendicular to the plate 100. It is easy to understand that through the cooperation between multiple connecting plates 11, the cover 2 can be engaged in a direction parallel to the plate 100.

[0065] In some examples, the cover 2 includes three flanges 22.

[0066] like Figure 3 As shown, the cover 2 includes a cover body 21 and three flanges 22. The three flanges 22 are located on the bottom wall, the first side wall and the second side wall of the cover body 21, respectively, and are connected to the cover 2.

[0067] The first sidewall and the second sidewall are two opposite sidewalls in the cover 2. For example, the first sidewall can be the left sidewall of the cover body 21 and the second sidewall can be the right sidewall of the cover body 21.

[0068] Correspondingly, such as Figure 4 As shown, connector 1 includes three connecting plates 11, each connecting plate 11 being arranged opposite to and snapped into a flange 22. The specific structure of the connecting plate 11 can be found in the description above, and will not be repeated here.

[0069] Optionally, multiple flanges 22 can be provided on any side wall of the cover body 21, and the multiple flanges 22 are engaged with a connecting plate 11. Specifically, the connector 1 may include three connecting plates 11, which may correspond to the bottom wall, the first side wall, and the second side wall of the cover body 21, respectively. For the cover body 21, its bottom wall, first side wall, and second side wall may each be provided with two flanges 22, and the two flanges 22 located on the same wall surface are spaced apart in a direction perpendicular to the plate 100.

[0070] In practice, the two flanges 22 on the bottom wall can be located on both sides of a connecting plate 11 and are respectively engaged with the connecting plate 11. The two flanges 22 on the first side wall can be located on both sides of a connecting plate 11 and are respectively engaged with the connecting plate 11. The two flanges 22 on the second side wall can be located on both sides of a connecting plate 11 and are respectively engaged with the connecting plate 11.

[0071] In one example, the cover body 21 and multiple flanges 22 are integrally formed. This improves the overall strength of the cover body 2.

[0072] For example, the cover body 21 and multiple flanges 22 can be formed by a stamping and bending process.

[0073] In one example, see Figure 3 The cover 2 includes two flanges 22, which are located on two opposite side walls of the cover body 21. See also Figure 4 The connector 1 includes three connecting plates 11, two of which are arranged opposite each other, with limiting portions 112 of each connecting plate 11 located between the two connecting portions 111. For the two oppositely arranged connecting plates 11, each connecting plate 11 corresponds to a flange 22, and each connecting plate 11 is engaged with a flange 22. The third connecting plate 11 is located below the two oppositely arranged connecting plates 11 and between the two oppositely arranged connecting plates 11, and the third connecting plate 11 abuts against the bottom wall of the cover body 21.

[0074] Optionally, the two connecting plates 11 arranged opposite each other can both extend in a vertical direction.

[0075] Specifically, see Figure 3 The cover body 21 has adjacent first sidewalls, second sidewalls, and a bottom wall. The first and second sidewalls are arranged opposite to each other, and each of the first and second sidewalls has a flange 22. See also Figure 4 The plate 100 is provided with three connecting plates 11, which correspond to the first side wall, the second side wall, and the bottom wall of the cover body 21, respectively. For example... Figure 3 and Figure 4 As shown, for two connecting plates 11 arranged opposite each other, the distance between the two connecting parts 111 is L1, and the distance between the two limiting parts 112 is the first distance L2. For two flanges 22 provided on the first side wall and the second side wall, the distance between the two flanges 22 is the second distance L3.

[0076] The first distance L1, the second distance L2, and the third distance L3 satisfy the following condition: L2 < L3 < L1. The first distance L1 refers to the distance between the edges of the two connecting parts 111 that are close to each other, the second distance L2 refers to the distance between the edges of the two limiting parts 112 that are close to each other, and the third distance L3 refers to the distance between the edges of the two flanges 22 that are far from each other.

[0077] Thus, the two connecting plates 11 arranged opposite to each other can limit the cover 2 in the horizontal direction. The third connecting plate 11 of the connector 1 can abut against the bottom wall of the cover body 21, thereby limiting the cover 2 in the vertically downward direction. Referring to the above description, the connector 1 can limit the cover 2 in the horizontal direction parallel to the plate 100, the vertically downward direction, and the direction perpendicular to the plate 100. The cover 2 can be stably connected to the plate 100 by the connector 1, and the cover control assembly 200.

[0078] In practice, when the control components, energy storage unit, and / or liquid cooling components malfunction, maintenance personnel can open the plate 100 and then simply lift the cover 2 upwards. This allows the cover 2 to move upwards along the gap 110 between the limiting part 112 and the plate 100, thereby separating the cover 2 from the connector 1. Compared to related technologies that use bolts to fasten the plate and cover together, the technical solution provided in this disclosure eliminates the need to tighten bolts, thus improving the maintenance efficiency of the liquid-cooled energy storage system.

[0079] In one example, see Figure 3 and Figure 4 A flange 22 may be provided on the bottom wall of the cover body 21. The third connecting plate 11 mentioned above includes a connecting part 111 and a limiting part 112. The specific structure of the connecting part 111 and the limiting part 112 can be referred to the above description, and will not be repeated here.

[0080] In this way, the limiting part 112 of the third connecting plate 11 can limit the flange 22 provided on the bottom wall in the direction perpendicular to the plate 100, thereby improving the connection stability and fit between the cover 2 and the plate 100.

[0081] In some examples, the limiting part 112 has a first snap-fit ​​structure 1121, and the flange 22 has a second snap-fit ​​structure 221.

[0082] In this design, the first snap-fit ​​structure 1121 is either a notch structure or a protrusion structure, and the second snap-fit ​​structure 221 is either a notch structure or a protrusion structure. That is, the first snap-fit ​​structure 1121 is a notch structure and the second snap-fit ​​structure 221 is a protrusion structure, or the first snap-fit ​​structure 1121 is a protrusion structure and the second snap-fit ​​structure 221 is a notch structure. Below, we will use the example of the first snap-fit ​​structure 1121 being a notch structure and the second snap-fit ​​structure 221 being a protrusion structure for further explanation.

[0083] like Figure 3 As shown, the flange 22 has multiple second snap-fit ​​structures 221 on the side away from the cover body 21, and the multiple second snap-fit ​​structures 221 are spaced apart along the length direction of the flange 22. See Figure 4 The limiting part 112 has a plurality of first snap-fit ​​structures 1121 on the side away from the connecting part 111, and the plurality of first snap-fit ​​structures 1121 are distributed at intervals along the length direction of the limiting part 112.

[0084] In practice, the protruding structure can pass through the notch structure, so that the flange 22 extends into the gap 110 between the limiting part 112 and the plate 100, or the flange 22 disengages from the gap 110 between the limiting part 112 and the plate 100.

[0085] In this way, when disassembling and assembling the cover 2, the maintenance personnel do not need to lift the cover 2 completely above the connector 1. Instead, they only need to lift the cover 2 upwards until the protruding structure and the notch structure are flush. Then, they can move the cover 2 along the direction perpendicular to the plate 100 to complete the disassembly and assembly of the cover 2, which further improves the convenience of disassembling and assembling the cover 2.

[0086] In one example, see Figure 3 The connector 1 includes two connecting plates 11 arranged opposite to each other. Each connecting plate 11 includes a connecting part 111 and a limiting part 112. The two limiting parts 112 have multiple spaced notch structures.

[0087] Optionally, the multiple notch structures on the two limiting parts 112 correspond one-to-one in the horizontal direction.

[0088] In another example, the connector 1 includes two connecting plates 11 arranged opposite to each other. One connecting plate 11 has a limiting portion 112 with a plurality of spaced notch structures, and the other connecting plate 11 has a limiting portion 112 without notch structures and may not be parallel to the plate body 100, that is, the limiting portion 112 without notch structures has an angle with the plate body 100.

[0089] In this way, when disassembling the cover 2, the cover 2 can be lifted upward until the protruding structure is flush with the notch structure. Then, the cover 2 is rotated slightly so that the protruding structure passes through the notch structure and extends out of the gap 110. Then, the cover 2 is moved along the extension direction of the limiting part 112 without the notch structure to complete the disassembly of the cover 2.

[0090] For example, see Figure 3 and Figure 4 The flange 22 may have five protruding structures arranged at intervals, and correspondingly, the limiting part 112 may have five notch structures arranged at intervals.

[0091] For example, the multiple protruding structures and multiple notch structures may all have rectangular structures, the multiple protruding structures have the same size, and the multiple notch structures have the same shape.

[0092] For example, the length of the first snap-fit ​​structure 1121 can be within the range of [40mm, 60mm]. It is easy to understand that when the length of the notch structure is too large, the improvement in the assembly and disassembly efficiency of the cover 2 is limited; when the length of the first snap-fit ​​structure 1121 is too small, the cover 2 is prone to detachment, resulting in poor connection stability. According to experimental data, when the length of the first snap-fit ​​structure 1121 is within the range of [40mm, 60mm], the assembly and disassembly efficiency of the cover 2 is significantly improved. Compared to the related technology that uses bolts to fasten the cover and the plate, the assembly and disassembly time can be shortened from 20 minutes to 8 minutes. Furthermore, the connection stability between the cover 2 and the plate 100 is also significantly improved.

[0093] For example, the length of the first snap-fit ​​structure 1121 can be 50 mm.

[0094] In some possible embodiments, the protective cover assembly also includes a positioning element 3.

[0095] like Figure 6 As shown, the connector 1 has a first limiting hole 101, and the flange 22 has a second limiting hole 222. The first limiting hole 101 and the second limiting hole 222 are arranged opposite to each other. The positioning member 3 passes through the first limiting hole 101 and the second limiting hole 222 in sequence to restrict the relative sliding between the flange 22 and the connector 1.

[0096] Specifically, see Figure 3 The second limiting hole 222 is located on the protruding structure, see [reference]. Figure 4 The first limiting hole 101 is located on the limiting part 112.

[0097] In this way, by setting the first limiting hole 101, the second limiting hole 222 and the positioning element 3, the cover 2 can be limited in the vertical upward direction, thereby further improving the connection stability between the cover 2 and the plate 100.

[0098] For example, both the first limiting hole 101 and the second limiting hole 222 are circular holes.

[0099] Optionally, the positioning element 3 can be a knurled screw, and the second limiting hole 222 can be a threaded hole. This can improve the connection stability between the positioning element 3 and the cover 2.

[0100] In some examples, such as Figure 2 As shown, a plurality of heat dissipation holes 211 are provided on the third side wall of the cover body 21. The plurality of heat dissipation holes 211 are arranged at intervals and are all arranged opposite to the EMS of the control component.

[0101] The third sidewall is the sidewall of the cover body 21 that is opposite to the plate body 100.

[0102] Specifically, see Figure 2 Multiple heat dissipation holes 211 can all be elongated.

[0103] In some examples, such as Figure 7 As shown, the top wall of the cover body 21 has a cable inlet hole 212. The cable inlet hole 212 can be a square hole, and the cable inlet hole 212 is used for the cable harness connecting the control component 200 to pass through.

[0104] The technical solutions provided in this disclosure have at least the following beneficial effects:

[0105] This disclosure provides a protective shield assembly in which a control component 200 is housed within a shield 2 and a plate 100. The shield 2 and the plate 100 are connected by a connector 1, rather than by bolts. This allows maintenance personnel to quickly and easily disassemble and reassemble the shield 2 and the plate 100 when the control component, energy storage unit, and / or liquid cooling heat dissipation component fail, thereby improving the maintenance efficiency of the liquid-cooled energy storage system.

[0106] This disclosure provides a liquid-cooled energy storage system, which includes a housing, a control component, an energy storage unit, a liquid-cooled heat dissipation component, and the aforementioned protective shield component.

[0107] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
