[0024] The utility model will be further described in detail below in combination with the drawings and specific embodiments.

[0025] Embodiment 1

[0026] As Figure 1 and2 As shown, the embodiment provides a kind of energy storage cabinet convenient to maintain, including cabinet 1 and cabinet door, cabinet 1 is divided into battery cabin, electrical cabin and liquid cooling machine cabin from top to bottom, battery cabin is used to set up energy storage battery 2, electrical cabin is used to set up high voltage box 3, DCDC 4, PCS 5, liquid cooling machine cabin is used to set up liquid cooling machine 6;Cabinet door has two front cabinet doors and rear cabinet doors 7.The high voltage box 3, DCDC 4 and PCS 5 are set in electrical cabin, close to the side of front cabinet door, the upper portion of the side close to rear cabinet door 7 of electrical cabin is equipped with support 8, and switch 9 is used to be set on support 8, distribution board 10 is hinged below support 8, and air switch, circuit breaker and other switch components are used to be set on distribution board 10, distribution board fixing piece 11 is equipped on the bottom surface of electrical cabin, and limiting structure is equipped between rear cabinet door 7 and cabinet 1, to maintain at least 90 degrees opening angle when rear cabinet door is opened.Such, when the electrical equipment in electrical cabin needs to be maintained, for example, line fault etc., only need to remove the connecting relationship between the lower end of distribution board 10 and distribution board fixing piece 11, and disconnect the wire harness 17 introduced from below distribution board 10, and open rear cabinet door 7 at least 90 degrees, the opening state of rear cabinet door 7 is fixed by limiting structure, then distribution board 10 is rotated outward, to expose the electrical equipment inside electrical cabin, and corresponding maintenance operation is carried out.Because the wire harness introduced from the upper portion of distribution board 10 is not pulled during the outward rotation of distribution board 10, the part of wire harness does not need to be disconnected, so that the operation of disconnecting and connecting wire harness is greatly reduced.When maintenance work is completed, only need to rotate distribution board 10 inward and reset, then the lower end thereof is connected and fixed with distribution board fixing piece 11 by bolt component, finally wire harness introduced from below is connected to distribution board 10.Therefore, in the whole maintenance process, the distribution board is avoided to be completely disassembled, and the plug and unplug and disassembly operation of a large number of wire harnesses is avoided, so that the overall maintenance efficiency is effectively improved.

[0027] As Figure 3 And 4As shown, the limiting structure comprises a limiting rod 12, a first connecting piece 13 and a second connecting piece 14 arranged on the rear cabinet door 7 and the cabinet body 1 respectively, the limiting rod 12 is rotatably connected with the first connecting piece 13, and the limiting rod 12 is detachably connected with the second connecting piece 14. In this way, the limiting rod 12 can be accommodated on the rear cabinet door 7, and when needed, it can be rotated outward at one end and connected with the second connecting piece. Specifically, the limiting rod 12 comprises a rod body 121, a first bending part 122 and a second bending part 123 arranged at two ends of the rod body 121, both of the two bending parts are arranged downward, the first bending part 122 is rotatably connected with the first connecting piece 13, the second connecting piece 14 is provided with a limiting hole 141 on the upper side, and the second bending part 123 is inserted and matched with the limiting hole 141. When in use, the end of the limiting rod 12 is rotated to the second connecting piece 14, and then the second bending part 123 is inserted downward into the limiting hole 141, so that the effective fixation of the limiting rod 12 can be realized, and the reset operation of the limiting rod 12 is also more convenient. Since the limiting rod 12 needs to be moved up and down by a certain distance during the insertion and matching process with the limiting hole 141, in order to avoid the limiting rod 12 from falling off the first connecting piece 13 during the process, a limiting ring 124 is arranged on the first bending part 122, and the first connecting piece 13 is limited between the rod body 121 and the limiting ring 124, and has an axial movement space.

[0028] In order to ensure the stability of the storage state of the limiting rod 12, the rear cabinet door 7 is provided with a limiting rod 12 storage part 15, the upper side of the limiting rod 12 storage part 15 is provided with a storage hole 151, and the second bending part 123 is inserted and matched with the storage hole 151, that is, when the limiting rod 12 is stored on the rear cabinet door, the second bending part 123 can be inserted downward into the storage hole 151 to realize stable storage.

[0029] In order to make the cooperation process of the limiting rod 12 and the second connecting piece 14 smooth, the second connecting piece 14 is provided with an upper limiting guide plate 142 above the edge away from the first connecting piece 13, and the limiting hole 141 is arranged on the second connecting piece 14 close to the upper limiting guide plate 142. In this way, the limiting rod 12 can move to the limiting hole 141 along the upper limiting guide plate 142, avoiding the limiting rod 12 from being too far or too close, and improving the assembly efficiency. In order to avoid the limiting rod 12 from extending below the second connecting piece 14, the second connecting piece 14 is provided with a lower limiting guide plate 143 below the edge close to the first connecting piece 13, and the lower limiting guide plate 143 is arranged obliquely, that is, the upper end is closer to the side of the second connecting piece 14 than the lower end, so as to guide the limiting rod 12 to the upper side of the second connecting piece 14.

[0030] As shown in the drawings, Figure 5As shown, the distribution board fixing member 11 comprises a first fixing plate 111 and a second fixing plate 112 connected perpendicularly to each other, and a reinforcing plate 113 is arranged between the first fixing plate 111 and the second fixing plate 112, and the first fixing plate 111 and the second fixing plate 112 are both provided with fixing holes to connect the distribution board 10 and the bottom surface of the electrical cabin by connecting members such as bolts.

[0031] Embodiment 2

[0032] For some relatively simple and quick maintenance work, since the power supply needs to be disconnected before the maintenance work, a single hand can be used to support the distribution board, and a single hand can be used to perform the maintenance operation; or the safety helmet on the head is used for support, and both hands are used to perform the maintenance operation; or two maintenance personnel cooperate to complete the maintenance work.

[0033] For some relatively complex and long duration maintenance work, the distribution board needs to be supported by a support rod, and the support rod 16 shown in the drawing can be used. Figure 6 As shown, the support rod 16 is provided with a support plate 161 near both ends, and the two ends of the support rod 16 are respectively matched with the hole on the distribution board for connecting the distribution board fixing member 11 and the limiting hole 141 on the second connecting member 14, the end of the support rod 16 is inserted into the hole, and at the same time, the support plate 161 abuts against the side surface of the distribution board 10 and the upper surface of the second connecting member 14, so as to support the state of the distribution board turned outwards.

[0034] The above is only a preferred specific embodiment of the present application, which is an implementation method based on the overall concept of the present application, and the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
