[0049] In the related art, the mounting assembly for installing the high-voltage circuit management module in the energy storage high-voltage box often uses a conventional mounting bracket to fix the mounting plate to the high-voltage box body. However, since the area near the mounting bracket is easily damaged, it does not meet the stability and safety requirements of the energy storage high-voltage box. To this end, the embodiment of the present application provides a mounting assembly, an energy storage high-voltage box, and an energy storage system. In the present application, the mounting assembly has multiple first mounting brackets and second mounting brackets, and the multiple first mounting brackets are respectively arranged near the top corners of the mounting plate, and the second mounting brackets are arranged near the second side of the mounting plate, while the circuit breaker is arranged near the first side of the mounting plate, wherein the second side is arranged opposite to the first side. Therefore, the arrangement of the second mounting bracket can effectively share the stress between the multiple first mounting brackets and the mounting plate, avoiding the occurrence of stress concentration between the first mounting brackets and the mounting plate, thereby optimizing the connection relationship between the mounting assembly structures, reducing the probability of damage in the area near the mounting brackets, and improving the stability and safety of the energy storage high-voltage box. For specific solutions, please refer to the following detailed description.

[0050] For details, please refer to Figure 1-2 The mounting assembly 100 specifically includes a mounting plate 101 and a mounting bracket 102; wherein the mounting plate 101 is configured to mount a high-voltage circuit management module 200; the high-voltage circuit management module 200 includes a circuit breaker 103, and the circuit breaker 103 is arranged close to the first side 105 of the mounting plate 101; the mounting bracket 102 is arranged on a side of the mounting plate 101 away from the high-voltage circuit management module 200, and can be fixedly connected to the bottom plate 104 of the high-voltage box body to fix the mounting plate 101 to the bottom plate 104; the mounting bracket 102 includes a plurality of first mounting brackets 106 and a second mounting bracket 107, and the plurality of first mounting brackets 106 are respectively arranged close to the top corners of the mounting plate 101, and the second mounting bracket 107 is arranged close to the second side 108 of the mounting plate 101, and the second side is arranged opposite to the first side.

[0051] The mounting assembly 100 provided in the present application has multiple first mounting brackets 106 and second mounting brackets 107, and the multiple first mounting brackets 106 are respectively arranged close to the top corners of the mounting plate 101, and the second mounting bracket 107 is arranged close to the second side 108 of the mounting plate 101, and the circuit breaker 103 is arranged close to the first side 105 of the mounting plate 101, wherein the second side 108 is arranged opposite to the first side 105. Therefore, through the arrangement of the second mounting bracket 107, the stress between the multiple first mounting brackets 106 and the mounting plate 101 can be effectively shared, and the stress concentration between the first mounting bracket 106 and the mounting plate 101 can be avoided, thereby optimizing the connection relationship between the structures of the mounting assembly 100, reducing the probability of damage in the area near the mounting bracket 102, and improving the stability and safety of the energy storage high-voltage box 10.

[0052] It should be noted that the high-voltage circuit management module 200 in the embodiment of the present application may also include a fuse (not marked in the figure), a relay (not marked in the figure), a pre-charge resistor (not marked in the figure), a battery management system (not marked in the figure) and a copper bus (not marked in the figure).

[0053] In some embodiments, as Figure 3 As shown, the second mounting bracket 107 includes a first connecting portion 109 and a plurality of first supporting portions 110, each of the first supporting portions 110 being connected to the first connecting portion 109; wherein the first connecting portion 109 is configured to be connected to the mounting plate 101;

[0054] The connection between the first connection portion 109 and the mounting plate 101 includes welding and bolt connection. When the bolt connection is adopted, a screw hole structure can be further provided on the first connection portion 109, wherein the number of screw holes includes at least one, for example Figure 3 In the embodiment, there are two screw holes on the first connecting portion 109.

[0055] It should be noted that the number of screw holes should tend to a balanced state, because the more screw holes there are, the higher the preparation cost of the second mounting bracket 107 is, but its stability is stronger.

[0056] Therefore, under the premise of ensuring the stability between the support plate and the second mounting bracket 107 , the fewer the screw holes, the better.

[0057] In the embodiment of the present application, by providing a plurality of first support portions 110 , the stress between the second mounting bracket 107 and the mounting plate 101 can be effectively shared, thereby preventing stress concentration between the second mounting bracket 107 and the mounting plate 101 .

[0058] In some embodiments, as Figure 3 As shown, the first supporting portion 110 includes a first transition portion 111 and a second connecting portion 112 . The first transition portion 111 is disposed between the first connecting portion 109 and the second connecting portion 112 .

When the bolt connection is adopted, the second connection portion 112 may also be provided with a screw hole structure, wherein the number of screw holes includes at least one, for example Figure 3 In the embodiment, there is one screw hole on the second connecting portion 112 .

[0060] It should be noted that the number of screw holes should tend to a balanced state, because the more screw holes there are, the higher the preparation cost of the second mounting bracket 107 is, but its stability is stronger.

[0061] Therefore, under the premise of ensuring the stability between the base plate 104 and the second mounting bracket 107 , the fewer the screw holes, the better.

[0062] Similarly, the number of the first supporting portions 110 depends on the stability between the second mounting support frame and the base plate 104 .

[0063] In the embodiment of the present application, by disposing the first adapter portion 111 , a certain distance can be maintained between the base plate 104 and the mounting plate 101 , thereby providing a certain redundant space therebetween.

[0064] In some embodiments, as Figure 3 As shown, the first connecting portion 109 has a third side 113, a fourth side 114, a fifth side 115 and a sixth side 116 connected end to end in sequence; wherein, the third side 113 is arranged opposite to the fifth side 115, the fourth side 114 is arranged opposite to the sixth side 116, and the length of the fourth side 114 is greater than the length of the third side 113; the number of the plurality of first supporting portions 110 is three, and the three first supporting portions 110 are respectively connected to the third side 113, the fourth side 114 and the fifth side 115.

[0065] The fourth side 114 of the second mounting bracket 107 is disposed close to the second side 108 of the bottom plate 104 , and the sixth side 116 of the second mounting bracket 107 is disposed close to the first side 105 of the bottom plate 104 .

[0066] In an embodiment of the present application, by setting the fourth side 114 of the second mounting bracket 107 close to the second side 108 of the base plate 104, and setting the sixth side 116 of the second mounting bracket 107 close to the first side 105 of the base plate 104, the stability between the base plate 104 and the mounting plate 101 can be effectively improved.

[0067] In some embodiments, as Figure 4 As shown, the first mounting bracket 106 includes a third connecting portion 117 and a plurality of second supporting portions 118 , each second supporting portion 118 is connected to the third connecting portion 117 ; wherein the third connecting portion 117 is configured to be connected to the mounting plate 101 .

[0068] The connection between the third connection portion 117 and the mounting plate 101 includes welding and bolt connection. When the bolt connection is adopted, the third connection portion 117 may also be provided with a screw hole structure, wherein the number of screw holes includes at least one, for example Figure 4 In the embodiment, there is one screw hole on the third connecting portion 117.

[0069] It should be noted that the number of screw holes should tend to a balanced state, because the more screw holes there are, the higher the preparation cost of the first mounting bracket 106 is, but its stability is stronger.

[0070] Therefore, under the premise of ensuring the stability between the support plate and the first mounting bracket 106 , the fewer the screw holes, the better.

[0071] In some embodiments, as Figure 4As shown, the second supporting portion 118 includes a second transition portion 119 and a fourth connecting portion 120 . The second transition portion 119 is disposed between the third connecting portion 117 and the fourth connecting portion 120 .

[0074] The number of the second supporting portions 118 is two, and the two second supporting portions 118 are connected to the seventh side 121 and the ninth side 123 respectively.

[0075] The ninth side 123 of the first mounting bracket 106 is disposed close to the second side 108 of the bottom plate 104 , and the seventh side 121 of the second mounting bracket 107 is disposed close to the first side 105 of the bottom plate 104 .

[0076] In this embodiment of the present application, by setting the ninth side 123 of the first mounting bracket 106 close to the second side 108 of the base plate 104, and setting the seventh side 121 of the second mounting bracket 107 close to the first side 105 of the base plate 104, the stability between the base plate 104 and the mounting plate 101 can be effectively improved.
