[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with its embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0028] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] The "first" and "second" in the present invention do not represent specific quantities and orders, but are only used to distinguish names.

[0031] On the one hand, if Figure 1 and Figure 2As shown, a distribution box in one embodiment of the utility model includes a box body 1, a mounting base plate 2 arranged in the box body 1, and a distribution module 3 arranged on the mounting base plate 2; the distribution module 3 includes an arc extinguisher unit 32, a relay unit 33, a fuse unit 34, and a control board unit 35 connected through a copper busbar unit 31; a raised heat dissipation flange is provided on the outer side of the box body 1.

[0032] The above-mentioned distribution box increases the contact area between the box body 1 and the outside air by providing a raised heat dissipation flange on the outside of the box body 1, thereby accelerating the transfer speed of the heat generated by the distribution module 3 to the outside air and improving the heat dissipation performance of the distribution box.

[0033] In one embodiment, the box body 1 is a cast aluminum shell, which has good heat dissipation performance. In addition, the cast aluminum shell has a relatively loose structure, which can meet the sealing requirements and accelerate the heat dissipation speed.

[0034] In one embodiment, the thickness of the cast aluminum housing is 3.5 mm to 4.5 mm. Specifically, the protrusion height of the heat dissipation flange is at least 0.5 mm. In this way, by limiting the protrusion height of the heat dissipation flange, it is possible to ensure that the contact area meets the heat dissipation requirements.

[0035] In one embodiment, the outer surface of the box body 1 is provided with a mounting hole, and the heat dissipation aluminum sheet is detachably mounted on the outer surface of the box body 1 through the mounting hole. In this way, the contact area between the box body 1 and the outside air is increased by providing the heat dissipation aluminum sheet, thereby further improving the heat dissipation performance of the distribution box.

[0036] In one embodiment, a support leg unit 4 is further included. The box body 1 is provided with at least two mounting surfaces on the front and rear sides, each of which has mounting holes. The support leg unit 4 includes connecting legs 41, the number of which matches the number of mounting surfaces. The connecting legs 41 are provided with an L-shaped mounting bracket, which has positioning holes that match the mounting holes and fixing holes for fixed installation. Specifically, triangular plates are provided on both sides of the L-shaped mounting bracket. In this way, the connecting legs 41 facilitate the installation of the box body 1 in different usage environments.

[0037] In one embodiment, a box cover 5 is further included. A connection structure 11 is provided on the top of the box body 1. This connection structure 11 includes a mounting groove, a sealing ring disposed within the mounting groove, and a set of connection holes disposed outside the mounting groove. The box cover 5 is provided with connection holes adapted to fit within the set of connection holes. Thus, the box cover 5 is secured to the box body 1 using fasteners, compressing the sealing ring within the mounting groove, thereby ensuring a sealed seal within the distribution box.

[0038] On the other hand, Figure 3As shown, a distribution box in an embodiment of the present invention includes a box body 6 and a distribution box 7; the distribution box is installed in the box body 6.

[0039] In one embodiment, the housing 6 is provided with an intermediate mounting plate 61, on which the power distribution box 7 is mounted. Removable doors 62 are provided on the left and right sides of the housing 6. Thus, by providing movable doors 62 on the left and right sides of the housing 6, maintenance and inspection of the power distribution box 7 are facilitated.

[0040] In one embodiment, the bottom and top of the movable door 62 are respectively provided with heat dissipation units 63. In this way, the heat dissipation units 63 are used to circulate the air inside the box body 6, so as to dissipate heat from the outer wall of the box body 1.

[0041] In one embodiment, the movable door 62 includes a first movable door and a second movable door, and the heat dissipation unit 63 includes a blowing unit disposed on the first movable door and a suction unit disposed on the second movable door. Specifically, the intermediate mounting plate 61 is provided with a plurality of ventilation holes. This allows air to circulate within the box 6, thereby improving the heat dissipation performance of the distribution box.

[0042] In one embodiment, the system further includes a display module 64 and an input control module 65. The display module 64 comprises two display screens, one located on the front and rear sides of the housing 6. The input control module 65 comprises two input units, one located on the front and rear sides of the housing 6. The input units comprise a drawer-type pull-out panel connected to the housing 6 and an input keyboard located on the pull-out panel. Thus, using the two display screens and two input units, the installation position of the housing 6 can be adjusted, allowing the input units to be used to control the distribution box from different locations. Simultaneously, the operating status of the distribution box 7 can be viewed in real time using the display screens.

[0043] In one embodiment, the bottom of the box body 6 is provided with an external interface 66 electrically connected to the distribution box 7. Specifically, the box body 1 is provided with a plurality of electrical interfaces electrically connected to the distribution module 3, and the electrical interfaces are connected to the external interface 66.

[0044] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
