[0062] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present utility model is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art.

[0063] Referring Figures 1-7 , this embodiment provides a container, which includes a box body 10 and a box door 20, and the box door 20 is rotatably connected to the box body 10.

[0064] The inside of the box door 20 has a hollow interlayer; the box door 20 also has a drain hole 300, and the drain hole 300 includes a bottom hole 310, the bottom hole 310 is opened at the bottom of the box door 20, and the bottom hole 310 communicates with the hollow interlayer. A diversion part 400 is arranged in the hollow interlayer, and the diversion part 400 is located at the bottom of the box door 20, and the diversion part 400 is used to divert water droplets towards the bottom hole 310. Thus, an effective drainage system is formed inside the box door 20, and water droplets that enter the inside of the box door 20 for whatever reason can be discharged from the hollow interlayer inside the box door 20 through the drain hole 300 (specifically, the bottom hole 310 at the bottom of the box door 20). On the one hand, it reduces the erosion of the box door 20 by moisture, extends the service life of the box door 20, and reduces the maintenance cost. On the other hand, it avoids the further penetration of moisture from the box door 20 into the inside of the container, enhancing the waterproof effect of the container. In addition, the setting of the diversion part 400 can promote the flow of water droplets towards the bottom hole 310, improving the drainage effect.

[0065] In some embodiments of the present utility model, referring Figure 5 , the drain hole 300 further includes a top hole 320. The top hole 320 is opened at the top of the box door 20, and the top hole 320 communicates with the hollow interlayer.

[0066] Referring Figure 1 and Figure 3 , the box body 10 further includes a door frame 11 located above the box door 10. There is inevitably a gap between the box door 20 and the door frame 11, and the setting of the top hole 320 can deal with the situation where rainwater seeps in from the top of the box door 20. When the top of the box door 20 is wetted by rainwater, the top hole 320 can timely introduce this moisture into the hollow interlayer and guide it through the diversion part 400 to be discharged from the bottom hole 310, thereby avoiding the accumulation of moisture inside the box door 20. In some cases, the cooperation of the top hole 320 and the bottom hole 310 can also be used as a ventilation hole to help the air circulation inside the box door 20 (i.e., the hollow interlayer), reducing the risk of dampness and mildew.

[0067] Optionally, the number of bottom holes 310 and top holes 320 is multiple, and the multiple bottom holes 310 and multiple top holes 320 are arranged along the length direction DL of the door 20. The arrangement of the multiple bottom holes 310 and top holes 320 increases the number of drainage channels, enabling moisture to be discharged from the interior of the door 20 more quickly and effectively preventing moisture accumulation.

[0068] Optionally, the opening positions of the multiple top holes 320 and the multiple bottom holes 310 correspond to each other in the height direction DH of the door 20. The corresponding layout of the top holes 320 and bottom holes 310 in the height direction DH allows the water flow to follow an almost straight path from the top holes 320 to the bottom holes 310, thus encountering relatively less resistance, which helps to accelerate the drainage speed of the water flow and further improve the drainage efficiency. In addition, the symmetric layout of the top holes 320 and bottom holes 310 helps to maintain the stability and balance of the structure of the door 20.

[0069] In some embodiments of the present utility model, the door 20 includes a frame 100 and an outer door panel 200. The outer door panel 200 faces the outside of the box, and the frame 100 faces the inside of the box.

[0070] The frame 100 includes a frame body 110 and an inner door panel 120. The outer door panel 200 and the inner door panel 120 are respectively connected to both sides of the frame body 110 in the width direction, so that a hollow interlayer as described above is enclosed between the inner door panel 120, the outer door panel 200, and the frame body 110. Optionally, the drainage holes 300 and the diversion part 400 in the above embodiments can be provided on any one or more of the frame body 110, the outer door panel 200, and the inner door panel 120.

[0071] The frame body 110, as the main load-bearing structure of the door 20, can provide sufficient rigidity and stability. Through the connection of the outer door panel 200 and the inner door panel 120, a more solid overall structure is formed, effectively enhancing the anti-deformation and anti-compression capabilities of the door 20.

[0072] Optionally, the frame 100 is welded to the outer door panel 200, and the inner door panel 120 is welded to the frame body 110. Welding ensures the tight connection of the joints of each component of the door 20, thereby indirectly improving the sealing effect.

[0073] In some embodiments of the present utility model, the frame body 110 forms a corner at the bottom of the door 20. Refer to Figure 2, the diversion part 400 is arranged at the corner, and the diversion part 400 has a diversion surface 410. The diversion surface 410 is arc-shaped, and one end of the diversion surface 410 is connected to the side of the frame body 110 extending along the height direction DH of the door 20, and the other end of the diversion surface 410 is connected to the side of the frame body extending along the length direction DL of the door 20. The diversion part 400 can guide the water flow to smoothly flow along the arc-shaped diversion surface 410 to the bottom hole 310, avoiding the accumulation of water at the corner. The diversion part 400 cooperates with the drain hole 300 to form a complete drainage path. When the accumulated water is guided by the diversion part 400 to the drain hole 300, it can be quickly discharged outside the container, further enhancing the waterproof effect of the container. Optionally, the diversion part 400 is fixedly connected to the frame body 110 to prevent it from falling off due to vibration or impact during transportation. The fixing methods include but are not limited to welding and bolt connection. Optionally, the diversion part 400 is integrally formed with the frame body 110. In other alternative embodiments, the diversion part 400 can be arranged at a non-corner according to actual needs, and its specific shape (or the diversion surface 410) can also be adjusted to a straight line instead of an arc shape.

[0074] Optionally, the door 20 further includes reinforcing ribs, and the reinforcing ribs are arranged in the hollow sandwich layer. The reinforcing ribs can increase the rigidity and strength of the door 20. By firmly connecting the reinforcing ribs to the door 20, the bending resistance, torsion resistance and impact resistance of the overall door 20 can be significantly improved. The reinforcing ribs include a plurality of transverse reinforcing ribs 510 and a plurality of longitudinal reinforcing ribs 520, and the transverse reinforcing ribs 510 and the longitudinal reinforcing ribs 520 are arranged in a cross pattern. The transverse reinforcing ribs 510 extend along the length direction DL of the door 20, and the longitudinal reinforcing ribs 520 extend along the height direction DH of the door 20. The transverse reinforcing ribs 510 and the longitudinal reinforcing ribs 520 are arranged in a cross pattern. The cross arrangement of the transverse reinforcing ribs 510 and the longitudinal reinforcing ribs 520 forms a stable grid structure, which can provide effective support in both the horizontal and vertical directions, thereby enhancing the structural strength of the door 20 in all directions. Optionally, the reinforcing ribs are connected to any one or more of the frame body 110, the outer door panel 200 and the inner door panel 120.

[0075] Optionally, referring to Figure 5 , the transverse reinforcing rib 510 is provided with an avoidance hole 511, and the avoidance hole 511 penetrates the transverse reinforcing rib 510 along the height direction DH of the door 20. The opening position of the avoidance hole 511 corresponds to the opening position of the drain hole 300 in the height direction DH of the door 20. Through the setting of the avoidance hole 511, while ensuring the strength of the door 20, when the door 20 has accumulated water, the water can smoothly drain through the drain hole 300 and the avoidance hole 511, avoiding the corrosion and damage of the internal structure of the door 20 caused by the accumulated water.

[0076] Optionally, a seal 30 is provided between the box body 10 and the box door 20 to ensure a tight fit between the box door 20 and the box body 10, further preventing rainwater from invading the interior of the container through the box door 20. Specifically, the seal 30 can be a strip structure made of a highly elastic material such as rubber or silica gel.

[0077] Referring to Figure 7 , the container further includes a humidity sensor 50 for detecting the internal humidity of the box body 10. Optionally, the humidity sensor 50 is a high-precision capacitive humidity sensor 50, whose humidity-sensitive film can adsorb water vapor in the air, thereby changing the capacitance and accurately measuring the humidity. When the humidity exceeds the preset threshold, the alarm system is automatically activated to send an alarm message to the management personnel for timely handling. The high-precision capacitive humidity sensor 50 can measure a large humidity range with small errors and is suitable for the relatively humid environment inside the refrigerated container. Optionally, in this embodiment, a wireless multi-channel transceiver communication chip is used to realize the real-time transmission of humidity data.

[0078] Referring to Figure 1 , the container further includes a window 40 arranged side by side with the box door 20. When the humidity inside the container is relatively high, the internal humidity of the container can be adjusted by opening the window. Specifically, when the humidity exceeds the preset threshold, the alarm system is automatically activated to send an alarm message to the management personnel, and the window 40 is manually operated to open.
