[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0028] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0029] In order to solve the problem of poor thermal management effect in air-cooled energy storage electric cabinets in the prior art, the utility model provides an electric cabinet.

[0030] like Figures 1 to 8 An electric cabinet shown in the figure includes a cabinet body 10, an electric box 20 and a guide structure 30, wherein the cabinet body 10 has an installation position with an opening on one side; the electric box 20 is movably installed in the installation position; the guide structure 30 includes a first guide portion 31 and a second guide portion 32, wherein the first guide portion 31 and the second guide portion 32 are respectively located on the installation position and the electric box 20, and at least one of the first guide portion 31 and the second guide portion 32 has a guide slope 33, and when the electric box 20 extends into the installation position, the first guide portion 31 abuts against the second guide portion 32, and the gap between the electric box 20 and the inner wall of the installation position is adjusted under the guidance of the guide slope 33.

[0031] In this embodiment, the cabinet 10 and the electrical box 20 are provided with a first guide portion 31 and a second guide portion 32 respectively, the first guide portion 31 and the second guide portion 32 constitute a guide structure 30, and one of the first guide portion 31 and the second guide portion 32 is further provided with a guide slope 33. Figure 3 As shown, when the electric box 20 is pushed into the installation position in the cabinet 10, the first guide portion 31 and the second guide portion 32 abut against each other. Due to the setting of the guide bevel 33, the first guide portion 31 and the second guide portion 32 move relative to each other under the guidance of the guide bevel 33. Since the first guide portion 31 is fixedly installed on the cabinet 10, the second guide portion 32 will be offset under the action of the guide bevel 33, so that the position of the electric box 20 is automatically adjusted, and then the electric box 20 can automatically adjust its position while being pushed into the cabinet 10, so that the gap between the left and right sides of the electric box 20 and the left and right sides of the installation position is basically equal, thereby ensuring that the sealing interfaces on the left and right sides are basically the same, thereby ensuring the thermal management effect of the electric cabinet.

[0032] In this embodiment, there are multiple guide structures 30, and the guide structures 30 are provided on both sides of the electric box 20 that are opposite to each other in the transverse direction. In this way, both sides of the electric box 20 that are opposite to each other in the transverse direction can be guided by the guide structures 30, thereby ensuring that the left and right sides of the electric box 20 can maintain a positional relationship with the inner wall of the installation position under the action of the guide structures 30 on both sides, thereby ensuring that the gaps on the left and right sides are substantially equal, further ensuring the thermal management effect. Of course, if the distance between one side of the electric box 20 and the inner wall of the cabinet 10 is already a fixed size, the guide structure 30 can be provided only on the other side of the electric box 20. For example, a fixed gap is formed between one side of the electric box 20 and the cabinet 10 by providing a guide rail or other structure. In this case, the guide structure 30 can be provided only on the other side, thereby ensuring that the gaps between the two sides of the electric box 20 and the cabinet 10 are substantially equal.

[0033] It should be noted that the two sides of the electric box 20 in this embodiment are the left and right sides of the electric box 20, that is, the left and right sides when a person normally operates the electric box 20, that is, when facing the electric box 20, or Figure 1 Correspondingly, the side of the electric box 20 facing the personnel, that is, the side of the electric box 20 located on the opening side is the outer side, that is, Figure 2 The upper side of the cabinet 10 is the inner side, and the side of the cabinet 20 away from the personnel, that is, the side of the cabinet 20 located deepest in the cabinet 10 is the inner side. Figure 2 The lower side of the .

[0034] Preferably, the guide slopes 33 of the guide structures 30 on both sides are inclined toward each other along the direction in which the electrical box 20 extends into the installation position. That is to say, along the direction from the outside to the inside, the guide slopes 33 of the guide structures 30 on the left and right sides of the electrical box 20 are inclined in the direction from the left and right sides to the middle axis, so that when the first guide portion 31 is abutted with the second guide portion 32, the guide slope 33 can guide the second guide portion 32 to move toward the center direction of the installation position, so that the gap on the side with a larger gap is reduced and the gap on the other side with a smaller gap is increased, so that the gaps on both sides are adjusted to be substantially the same in size.

[0035] In this embodiment, the installation position has an opening side and a positioning side that are relatively arranged. When the electrical box 20 is installed in the installation position, it has a first side located at the opening side and a second side located at the positioning side. The first side here is the outer side mentioned above, and the second side is the inner side mentioned above. The opening side and the outer side are Figure 2 The upper side, the in-position side and the inner side are Figure 2 The lower side of the. In this embodiment, the first guide portion 31 is located at the side in place, and the second guide portion 32 is located at the second side, that is, the guide structure 30 is arranged at the inner side of the electric box 20 and the corner of the side in place of the installation position, so that when the electric box 20 begins to be pushed into the installation position, the distance between the first guide portion 31 and the second guide portion 32 is relatively far, and there is no abutment relationship between the two. When the electric box 20 is about to be completely pushed into place, the first guide portion 31 and the second guide portion 32 will abut, and then the guide structure 30 will play a role in adjusting the position of the electric box 20, so as to achieve the effect that the size of the gap on the left and right sides of the electric box 20 is basically the same. The above-mentioned setting method can ensure that the position of the electric box 20 is accurate and reliable when it is in place. Of course, in addition to setting the guide structure 30 on the side in place, the guide structure 30 can also be set at other positions in the front-to-back direction, so that the position of the electric box 20 can be adjusted during the pushing process.

[0036] like Figures 3 to 5 As shown, in this embodiment, the first guide portion 31 is a guide block, which is located at the corner of the side in place, that is, at the left and right ends of the side in place, and the second guide portion 32 is a guide recess, which is located at the corner of the second side, that is, at the left and right ends of the inner side. In addition, in this embodiment, guide slopes 33 are provided on both the first guide portion 31 and the second guide portion 32, so that when the first guide portion 31 and the second guide portion 32 are in contact, the guide slopes 33 of the two guide portions contact and cooperate with each other, thereby ensuring the reliability of the guiding effect.

[0037] Of course, in addition to the above-mentioned guide blocks and guide recesses, other structural forms may also be used. For example, a groove is provided on the seating side of the installation position, and a protrusion is provided on the inner side of the electrical box 20. The guiding adjustment function of the guide structure 30 is achieved through the cooperation of the groove and the protrusion.

[0038] like Figure 5 As shown, in the present embodiment, the end of the first guide portion 31 facing the opening side of the installation position has a rounded structure 34, that is, the end of the first guide portion 31 facing the outside has a rounded structure 34, so that when the electrical box 20 is extended into the installation position, since the electrical box 20 is generally not aligned when manually pushed in, the guide slope 33 of the second guide portion 32 will generally contact the rounded structure 34 first, so that the second guide portion 32 moves toward the guide slope 33 of the first guide portion 31 under the guidance of the rounded structure 34, so that the guide slope 33 of the second guide portion 32 abuts against the guide slope 33 of the first guide portion 31, and then the reliable adjustment of the left and right position of the electrical box 20 is achieved through the guiding effect of the guide slope 33.

[0039] In this embodiment, since both the first guide portion 31 and the second guide portion 32 have a guide slope 33, this embodiment adopts a setting mode in which the guide slope 33 of the first guide portion 31 and the guide slope 33 of the second guide portion 32 are parallel to each other. Figure 4 and Figure 5 As shown, the guide slope 33 of the first guide part 31 forms an angle b with the direction in which the electric box 20 extends into the installation position, and the guide slope 33 of the second guide part 32 forms an angle a with the direction in which the electric box 20 extends into the installation position, and the angle a=angle b. In this way, the guide slope 33 of the first guide part 31 and the guide slope 33 of the second guide part 32 are in surface contact, thereby ensuring the smoothness and reliability of the guide. The first guide part 31 of this embodiment is wedge-shaped, and the second guide part 32 is formed by cutting off a part of the inner corner of the electric box 20. Of course, in addition to setting the guide slope 33 on both the first guide part 31 and the second guide part 32, the guide slope 33 can also be set on only one of them, for example, the guide slope 33 is set only on the second guide part 32, and the first guide part 31 is a rectangular block structure. At this time, the guide slope 33 of the second guide part 32 abuts against the corner of the first guide part 31, and the guide adjustment of the left and right positions of the electric box 20 can also be achieved.

[0040] Preferably, the direction in which the electrical box 20 extends into the installation position forms an angle of 10-30 degrees with the guiding inclined surface 33, so that the smoothness of the relative movement when the guiding inclined surface 33 contacts can be ensured.

[0041] like Figures 6 to 8 As shown, in this embodiment, when the electrical box 20 is installed in the installation position, due to the adjustment of the guide structure 30, when it is finally pushed into place, the sizes of the two gaps formed between the two opposite sides of the electrical box 20 and the inner wall surface of the installation position are equal, that is, Figure 7 and Figure 8 The gap m=n in the heat dissipation controller, thereby improving the thermal management effect.

[0042] The electric cabinet of this embodiment also includes a sealing structure, and there is a sealing structure between the two sides of the electric box 20 that are opposite to each other in the horizontal direction and the inner wall surface of the installation position. With the arrangement of the aforementioned guide structure 30, the sealing interface conditions on the left and right sides of the electric box 20 can be made almost the same, thereby reducing the impact on the thermal management of the air-cooled electric cabinet system.

[0043] It should be noted that, the multiple in the above embodiments refers to at least two.

[0044] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0045] 1. Solve the problem of poor thermal management effect in the air-cooled energy storage cabinet in the prior art;

[0046] 2. The electric box can automatically adjust its position when it is pushed into the cabinet, so that the gaps between the left and right sides of the electric box and the left and right sides of the installation position are basically equal, thereby ensuring that the sealing interfaces on the left and right sides are basically the same, thereby ensuring the thermal management effect of the electric cabinet.
