[0088] Please see now Figure 2 The door 120 includes a door panel 121 and an outer frame 131. The outer frame 131 is located on the outer periphery of the door panel 121 and connected to the door panel 121. Specifically, the outer frame 131 includes a door crossbeam 122 and a door vertical beam 123. The door crossbeam 122 is arranged along the width direction of the container 100 and connected to the door panel 121. The door vertical beam 123 is arranged along the height direction DH of the container 100 and connected to the door panel 121 and the door crossbeam 122. It should be noted that there are two door crossbeams 122 and two door vertical beams 123. Two adjacent door crossbeams 122 are spaced apart along the height direction DH of the container 100, and two adjacent door vertical beams 123 are spaced apart along the width direction DW of the container 100. Both door crossbeams 122 are located between two adjacent door vertical beams 123.

[0089] Please see now Figure 3 and Figure 4 The door panel 121 includes, from top to bottom along the height direction DH of the door panel 121, a top wave portion 124, a top plate portion 125, a first wave portion 126, a bottom plate portion 127, and a second wave portion 128. Please refer to the following reference: Figure 1and Figure 2 The two first brackets 142 are located at the top plate 125 and the bottom plate 127 of the door panel, respectively. The two second brackets 143 are located at the two door crossbeams 122, respectively.

Hinge 44 corresponds to the area where the second wave portion 128 of the door panel meets the door crossbeam 122.

[0090] The improved container structure of this utility model will be described below.

[0091] Please see Figures 5 to 8 The door panel 221 includes a top panel portion 225, a first wave portion 226, a bottom panel portion 227, and a second wave portion 228 arranged sequentially from top to bottom along the height direction DH of the door panel 221. (See also...) Figure 9 Along the height direction DH of door panel 221, the dimension of the top panel portion 225 is L1, and the dimension of the bottom panel portion 227 is L2, where L1 > L2. Further details can be found in the following section. Figure 10 The top part 325 of the door panel is provided with at least one groove 350.

[0092] Compared to the aforementioned prior art door panels, the door panel of this solution eliminates the top wave section, simplifying manufacturing. Furthermore, since the top panel is larger than the bottom panel, larger logos can be affixed to the top panel, achieving a superior visual effect. Additionally, the top panel features grooves that prevent deformation caused by welding to the door frame from extending to the bottom of the door panel, thus improving the flatness of the top panel.

[0093] Please see now Figures 5 to 9 It should be noted that the first wave position portion 226 of the door panel includes multiple wave structures 229 arranged sequentially along the height direction DH of the door panel 221. Preferably, the number of wave structures 229 is greater than or equal to three. For example... Figure 5 In the example, waveform structure 229 has three instances. Figure 8In this design, there are four wave structures 229. This is because, during container freight, the deformation is often greatest at the first wave position 226 of the door panel. This design enhances the strength of the first wave position 226 of the door panel, effectively resisting the deformation caused by the pressure of the cargo inside the container on the door end, and improving the service life of the container.

[0094] Please see Figure 10 The groove 350 is provided along the width direction DW of the door panel 321. Along the width direction DW of the door panel 321, the dimensions of the groove 350 are the same as the dimensions of the door panel 321, and the groove 350 is constructed as a through groove open at both ends. Please refer to [link / reference]. Figure 11 and Figure 12 The cross-sectional structure of the 350mm groove reinforcement is arc-shaped. Alternatively, please refer to... Figure 13 and Figure 14 , Figure 13 In the middle, the cross-sectional structure of the groove 450 is a V-shape with an opening facing the thickness direction of the door panel 321; Figure 14 In the middle, the cross-sectional structure of the groove rib 525 is a trapezoid with an opening in the thickness direction toward the door panel 321. Please refer to... Figure 15 , Figure 15 A door panel 421 is shown. Compared with the aforementioned door panel 321, the difference is that the dimension of the groove 650 at the door panel 421 along the width direction DW of the door panel 421 is smaller than the dimension of the door panel 421, and the groove 650 is constructed as a blind groove closed at both ends.

[0095] Please return to the reference section. Figure 10 and Figure 11 The number of groove ribs 350 is one, and they are arranged along the width direction DW of the door panel 321. Specifically, along the height direction DH of the door panel 321, the groove rib 350 has a first edge 351 near the first wave position portion 226 of the door panel and a second edge 352 away from the first wave position portion 226 of the door panel. The top plate portion 325 of the door panel has a bottom edge 353 that connects to the first wave position portion 226 of the door panel. The distance between the first edge 351 and the bottom edge 353 is L3, where L3 > L2. It should be noted that, regardless of whether L3 or the aforementioned L1, the height of the top plate portion of the door panel can be selectively adjusted to be greater than or much greater than the height of the bottom plate portion of the door panel, thereby giving the top plate portion of the door panel a larger flat area, allowing larger-sized trademarks to be properly pasted and achieving excellent visual effects.

[0096] Please return to the reference section. Figure 5 and Figure 6 Container 200 includes a container body and a container door 110. The container door 110 is connected to the container body. The container door 110 includes a door leaf 220 and a door frame 111, the door frame 111 being located on the outer periphery of and connected to the door leaf 220. See also... Figure 7The door leaf 220 includes an outer frame 131 and a door panel 221, with the outer frame 131 connected to the door panel 221. It should be noted that at least two first brackets 142 are located at the center of the locking rod 141, and the first brackets 142 are connected to the locking rod 141 and the bottom plate portion 227 of the door panel. At least one first bracket 142 is located at the first wave position portion 226 of the door panel, and at least one first bracket 142 is located at the bottom plate portion 227 of the door panel. It is understood that the handle and handle seat may also correspond to the position of the bottom plate portion 227 of the door panel for convenient operation. Figure 6 In this configuration, there are two first brackets 142, spaced apart along the height direction DH of the door panel 221. The upper first bracket 142 connects to the first wave position portion 226 of the door panel, specifically, it is located at the plane position where two adjacent wave structures 229 meet along the height direction DH. The lower first bracket 142 connects to the bottom plate portion 227 of the door panel. This arrangement ensures that the first brackets 142 do not occupy the area of ​​the top plate portion 225 of the door panel.

[0097] Please see Figure 6 , Figure 16 and Figure 17 The door end 110 includes multiple hinges 130. These hinges 130 are spaced apart along the height direction DH of the container 200 and are connected to the door frame 111 and the door leaf 220. It is understood that the door frame 111 is a frame structure formed by the interlocking of a lintel beam 112, a sill beam 113, and corner posts 114. It should be noted that at least two hinges 130 are positioned between the door frame 111 and the door leaf 220 corresponding to the area of ​​the first wave portion 226 of the door panel. The hinges 130 are connected to the outer frame 131 and the door frame 111. As described above, the first wave portion 226 of the door panel includes multiple wave structures 229 arranged sequentially along the height direction DH of the container 200. Along the height direction DH of the container 200, the first wave portion 226 of the door panel has a first wave structure closest to the top plate portion 225 and a second wave structure closest to the bottom plate portion 227. At least one hinge 130 is positioned corresponding to the first wave-shaped structure area, and at least one hinge 130 is positioned corresponding to the second wave-shaped structure area. The hinge 130 is spaced apart from the wave-shaped structure 229 along the width direction DW of the container 200. This arrangement can greatly reduce welding deformation at the door panel and the vicinity of the hinge 130 caused by welding of the hinge 130.

[0098] According to the present invention, the container door has superior strength, which can effectively resist the deformation caused by the pressure of the cargo inside the container on the container door, and effectively avoid the deformation caused by the welding of the hinge on the door panel. Moreover, the door panel has a larger top panel area, which allows for the proper pasting of larger trademarks and achieves excellent visual effect.
