The box body 1 includes a base 6, a box body side plate 7 vertically connected to the left and right sides of the base 6, and a box body sealing plate vertically connected to the front and rear sides of the base 6.

As shown in FIG4 , the box body side panels 7 each include a first vertical panel section 8, an inclined panel section 9, and a second vertical panel section 10. The inclined panel section 9 gradually tilts upward from the outside of the box body 1 toward the inside of the box body 1. The inclined panel section 9 is parallel to the above-mentioned inclined surface and has a set interval. The second vertical panel section 10 is parallel to the corresponding side cover body side panel 4 and is arranged at intervals. The distance between the inclined panel section 9 and the inclined surface, and the distance between the second vertical panel section 10 and the cover body side panel 4 are equal. The interval space between the inclined panel section 9 and the second vertical panel section 10 and the corresponding cover body side panel 4 forms a heat dissipation channel 5 for air circulation.

As shown in FIG1 , two baffles 12 are symmetrically arranged in the left and right directions on the base 6. The two baffles 12 are respectively parallel to the second vertical plate section 10 on the corresponding side and are arranged at intervals and connected to the box body sealing plates on the front and rear sides. The space enclosed by the two baffles 12 and the base 6 and the two box body sealing plates is used to place the controller 11. The base 6 is provided with a threading hole 13 at the position corresponding to the controller 11. The threading hole 13 is sealed, such as placing a sealing ring, and the cable passes through the sealing ring to prevent water from entering the box body from the threading hole 13. The height of the upper surface of the baffle 12 is higher than the height of the upper surface of the second vertical plate section 10. The baffle 12 and the corresponding box body side plate 7, the box body sealing plate and the bottom plate form a drainage cavity 14. A plurality of drainage holes 15 arranged in an array are provided in the area corresponding to the drainage cavity 14 on the base 6. In normal weather, the drainage hole 15 can be used as a heat dissipation hole.

As shown in Figure 5, the handle 3 includes an upper limit segment 16, a lower limit segment 17, an upper clamping segment 18, a lower clamping segment 19 and a grip segment 20. The upper limit segment 16 and the lower limit segment 17 are respectively connected to the upper and lower sides of the grip segment 20. The upper clamping segment 18 is connected to one end of the upper limit segment 16 away from the grip segment 20 and extends upward. The lower clamping segment 19 is connected to one end of the lower limit segment 17 away from the grip segment 20 and extends downward.

The cover side plate 4 and the first vertical plate section 8 are both provided with a step groove corresponding to the handle 3, as shown in Fig. 3, the step groove includes a first horizontal step surface 21, a second horizontal step surface 22, a third horizontal step surface 23, a first vertical step surface 24 and a second vertical step surface 25. The first horizontal step surface 21 and the third horizontal step surface 23 extend to the corresponding side surfaces of the cover side plate 4 and the first vertical plate section, the second horizontal step surface 22 is located on the inner side of the first horizontal step surface, the first vertical step surface 24 is connected between the first horizontal step surface 21 and the second horizontal step surface 22, the second vertical step surface 25 is connected between the second horizontal step surface 22 and the third horizontal step surface 23, and the second horizontal step surface 22, the second vertical step surface 25 and the third horizontal step surface form a clamping groove 29 for clamping with the upper clamping section 18 or the lower clamping section 19. The length of the clamping groove 29 in the front-to-back direction is adapted to the length of the upper limit segment 16 and the lower limit segment 17, and the depth of the clamping groove 29 in the left-to-right direction is adapted to the thickness of the upper clamping segment 18 and the lower clamping segment 19 in the left-to-right direction. As shown in Figures 2 and 6, the first horizontal step surface 21 is provided with a mounting groove 28 extending in the up-down direction, and a stopper 27 is slidably mounted in the mounting groove 28. A spring 26 is fixed between the stopper 27 and the mounting groove 28, and the spring 26 is used to drive the stopper 27 to press the corresponding upper limit segment 16 or the lower limit segment 17. The distance between the third horizontal step surface 23 of the step groove on the cover body side plate 4 and the third horizontal step surface 23 of the step groove on the first vertical plate segment 8 is equal to the distance between the upper limit segment 16 and the lower limit segment 17. In this way, after installation, the upper limit segment 16 is blocked and matched with the cover body side plate 4 downward, and the lower limit segment 17 is blocked and matched with the first vertical plate segment 8 upward.

When installing the vehicle control box of the utility model, the handle 3 on one side is installed first, that is, the block 27 in the box body side plate 7 is pressed downward first, the lower clamping section 19 of the handle 3 is clamped into the clamping groove 29 on the box body side plate 7, and the block 27 in the box body side plate 7 is released. Under the action of the spring 26 in the box body side plate 7, the block 27 is pressed upward against the lower limit section 17, and the lower limit section 17 and the third horizontal step surface 23 on the box body side plate 7 are blocked upward; then the block 27 in the cover body side plate 4 is pushed upward, the upper clamping section 18 of the handle 3 is clamped into the clamping groove 29 in the cover body side plate 4, and the block 27 in the cover body side plate 4 is released. Under the action of the spring 26 in the cover body side plate 4, the block 27 is pressed downward against the upper limit section 16, and the upper limit section 16 and the third horizontal step surface 23 on the cover body side plate 4 are blocked downward. The handle 3 on the right side can be installed according to the same steps. After the handle 3 is installed, the cover body is buckled on the outside of the box body as a whole. The cover body and the box body are relatively fixed by the handle 3 and are not easy to separate. No fasteners such as bolts are required, and installation and disassembly are relatively convenient. The gap between the cover body and the box body can be used for heat dissipation. A connecting hole is provided on the grip section 20, and the entire vehicle control box is connected to the frame through the grip sections 20 on the two handles 3. After long-term use, the handle 3 can be removed to blow away the dust in the control box.

The heat dissipation channel 5 on the vehicle control box can not only play a heat dissipation effect, but also form a certain barrier to rainwater when rainwater splashes, forcing rainwater to slide down the heat dissipation channel 5. Even if rainwater enters the box body through the heat dissipation channel 5, it will first flow into the drainage cavity 14 and flow out along the drainage groove, and will not enter the space where the controller 11 is placed, thereby forming a good waterproof protection for the controller 11, and the drainage groove can also be used as a heat dissipation groove in normal weather, realizing multi-purpose integration and reducing the failure rate of the controller 11 in rainy weather.
