[0022] The above-mentioned parts are mature existing technologies, which have been disclosed in Chinese patent with authorization announcement number CN208209325U, and will not be described again in this technical solution;

[0023] The core of this technical solution is that an air outlet is provided on one side of the adjustable air outlet 4. The vertical cross-sectional dimension of the air outlet is adjustable, thereby adjusting the air outlet area and area of ​​the adjustable air outlet 4, so that the air outlet of the adjustable air outlet 4 is compatible with the position of the electrical components inside the distribution box 1, and better heat dissipation of the electrical components inside the distribution box 1.

[0024] Specifically, such as Figures 1-3 As shown, the adjustable air outlet 4 includes an air outlet shell 5 fixedly connected to the inner wall of the distribution box 1. The air outlet shell 5 is connected to the air radiator 3. An opening area 6 is opened on one side of the air outlet shell 5. Two baffles 8 are slidably connected to the side of the air outlet shell 5 with the opening area 6. Linear movement groups 7 are fixedly connected to the upper and lower sides of the air outlet shell 5. The linear movement groups 7 are connected to the baffles 8 through a transmission. The linear movement groups 7 can be electric push rods or linear motors, as long as they can drive the baffles 8 to move vertically. By moving the baffles 8, the obstruction of the opening area 6 by the baffles 8 is adjusted. The area of ​​the opening area 6 that is not obstructed by the baffles 8 is the air outlet of the adjustable air outlet 4, thereby effectively controlling the height of the air outlet.

[0025] like Figures 2-3As shown, the inside of the air outlet shell 5 is provided with a retractable wind shielding structure on both sides, which can be expanded towards the center of the opening area 6, so as to adjust the shielding of the opening area 6 by the retractable wind shielding structure. At this time, the area of the opening area 6 not shielded by the wind shielding plate 8 and the retractable wind shielding structure is the air outlet of the adjustable air outlet 4, so that the width of the air outlet can be controlled.

[0028] The horizontal moving mechanism includes a connecting piece 13 fixedly connected to the movable end of the flexible wind shielding belt 9. A return spring 14 is fixedly connected between the connecting piece 13 and the side wall of the air outlet shell 5. By providing the return spring 14, the movable end of the flexible wind shielding belt 9 can be automatically moved towards the center of the opening area 6 after the flexible wind shielding belt 9 is unwound.

[0029] The inside of the air outlet shell 5 is also fixedly connected with a guide rod 15. The connecting piece 13 is slidingly connected to the outside of the guide rod 15, and the return spring 14 is sleeved on the outside of the guide rod 15, which is used to limit and guide the connecting piece 13 and the return spring 14.
