[0037] Such as Figures 1 to 8As shown in the figure, the present utility model provides an external sealing structure, which includes a surrounding member 1 and a top cover 2. The surrounding member 1 is configured to surround and be fixed to the side end of the frame 101. The surrounding member 1 includes a surrounding portion 11 and a first resisting portion 12. One end of the surrounding portion 11 close to the frame 101 extends upward to form the first resisting portion 12. The top surface of the surrounding portion 11 is communicated with the side surface of the first resisting portion 12 to form a surrounding groove 13. The top cover 2 is detachably connected to the surrounding member 1 and is configured to cover the top end of the frame 101. The top cover 2 includes a cover body 21 and a fitting portion 22 fixed to the outer edge of the cover body 21. The fitting portion 22 is located in the surrounding groove 13, and the bottom surface of the fitting portion 22 can be attached to and tightly pressed against the top surface of the surrounding portion 11. As Figure 2 and Figure 4 shown in the figure, by providing the surrounding groove 13, when rainwater enters the cargo box through the gap between the surrounding member 1 and the top cover 2, due to the upward extension of the first resisting portion 12, the rainwater will be blocked by the first resisting portion 12 and flow out through the gap between the surrounding member 1 and the top cover 2, thereby preventing the rainwater from flowing into the cargo box. In addition, when rainwater enters the cargo box through the gap between the surrounding member 1 and the top cover 2, since the bottom surface of the fitting portion 22 is attached to and tightly pressed against the top surface of the surrounding portion 11, the difficulty of rainwater entering is increased, and the rainwater can be further prevented from flowing into the cargo box.

[0038] On the basis of not adding components, the external sealing structure of the present utility model can ensure the sealing performance of the cargo box by improving the internal structure of the cargo box, that is, the existing top plate and side plate. The structure of the cargo box is simple, with a high degree of integration, reducing the assembly process and development cycle of the cargo box, and the sealing effect of the cargo box is good.

[0039] Optionally, in this embodiment, as Figure 4 shown in the figure, one end of the surrounding portion 11 close to the frame 101 extends upward in the vertical direction to form the first resisting portion 12. The first resisting portion 12 extends upward in the vertical direction, which is convenient for processing the first resisting portion 12 and can better prevent rainwater from entering the frame 101 from the top of the first resisting portion 12. Further, a chamfer is provided at the connection between the top surface of the surrounding portion 11 and the side surface of the first resisting portion 12 to avoid rainwater accumulation at the connection. In other embodiments, one end of the surrounding portion 11 close to the frame 101 extends obliquely upward to form the first resisting portion 12, and the included angle between the top surface of the surrounding portion 11 and the side surface of the first resisting portion 12 is an acute angle or an obtuse angle. When the included angle is an acute angle, the first resisting portion 12 inclines towards the direction close to the fitting portion 22, and when the included angle is an obtuse angle, the first resisting portion 12 inclines towards the direction away from the fitting portion 22, as long as it can block rainwater from entering, and this embodiment is not limited thereto.

[0040] Optionally, in this embodiment, the fitting portion 22 is a V-shaped bent plate. One end of the V-shaped bent plate is fixed to the cover body 21. The opening of the V-shaped bent plate faces the first blocking portion 12, and the bottom surface of the V-shaped bent plate fits against the top surface of the enclosure portion 11. The fitting portion 22 being a V-shaped bent plate saves materials, is convenient for processing, and can reduce the weight of the overall structure. The opening of the V-shaped bent plate facing the first blocking portion 12 can prevent rainwater from accumulating on the top cover 2. In addition, in this embodiment, the cover body 21 and the fitting portion 22 are integrally provided, which is more convenient for processing the top cover 2. In other embodiments, the fitting portion 22 is a V-shaped bent plate. One end of the V-shaped bent plate is fixed to the cover body 21. The opening of the V-shaped bent plate faces away from the first blocking portion 12, that is, the opening of the V-shaped bent plate faces outward, and the bottom surface of the V-shaped bent plate fits against the top surface of the enclosure portion 11. The side surface of the V-shaped bent plate close to the first blocking portion 12 fits against the side surface of the first blocking portion 12. This setting makes the V-shaped bent plate fit completely with the groove surface of the enclosure groove 13 and can also prevent rainwater from flowing into the cargo box.
