[0048] Now, refer to Figures 1 to 6 Exemplary embodiments according to the present invention are described in more detail.

[0049] On one hand, the present application provides a door sealing structure, which includes a door frame portion 110 and a door portion 130. The door frame portion 110 has a doorway, and the door frame portion 110 is provided with a first elastic sealing portion 111. The door portion 130 is openably and closably arranged on the door frame portion 110 to open or close the doorway, and a second elastic sealing portion 131 is provided on the surface of the door portion 130 facing the door frame portion 110. When the door portion 130 closes the doorway, the first elastic sealing portion 111 is connected to the second elastic sealing portion 131, and the first elastic sealing portion 111 and the second elastic sealing portion 131 form an interference fit.

[0050] According to the door sealing structure of the present application, two elastic sealing parts form a sealing structure, which improves the sealing redundancy, avoids the overall sealing failure caused by the failure of a single sealing part, and has high reliability. In addition, the butt-sealing form of the two elastic sealing parts can also compensate for the flatness error of the door part, further improving the sealing reliability.

[0051] Specifically, refer to Figure 2 and Figure 3 The door frame part 110 has a first bending portion 114 extending toward the door part 130, and a first flange 115 is provided at the end of the first bending portion 114. The first flange 115 extends in a direction away from the center of the door part 130, and the first elastic sealing portion 111 is provided at the first flange 115. The first elastic sealing portion 111 includes a mounting portion 112 and a sealing portion 113 connected to the mounting portion 112, and the mounting portion 112 is sleeved on the first flange 115. Preferably, the first bending portion 114 is perpendicular to the main surface of the door frame part 110, and the first flange 115 is perpendicular to the first bending portion 114. In other words, the first flange 115 is preferably provided parallel to the main surface of the door frame part 110.

[0052] The door portion 130 is provided with a second bent portion 132 extending toward the door frame portion 110, and a second flange 133 is provided at the end of the second bent portion 132, and the second flange 133 extends in a direction close to the center of the door portion 130. In addition, the second elastic sealing portion 131 is spaced apart from the second bent portion 132. The second bent portion 132 is perpendicular to the inner surface of the door portion 130 or the surface facing the door frame portion 110, and the second flange 133 is perpendicular to the second bent portion 132. In other words, the second flange 133 is preferably arranged parallel to the inner surface of the door portion 130.

[0053] And further preferably, the first flange 115 and the second flange 133 extend toward each other, thereby increasing the degree of tortuosity of liquid entering through the doorway and reducing the probability of water leakage.

[0054] As an implementation form, the first elastic sealing portion 111 is continuously arranged around the door opening, and the second elastic sealing portion 131 is continuously arranged along the circumference of the door portion 130. Thus, the complete sealing of the entire door frame portion 110 is achieved.

[0055] Among them, Figure 3 In the illustrated embodiment, when the door portion 130 and the door frame portion 110 are closed, the sealing portion 113 of the first elastic sealing portion 111 extends toward the door portion 130 and tightly abuts against the second elastic sealing portion 131 provided on the inner surface of the door portion 130 to form a seal.

[0056] As another optional implementation, refer to Figure 2 , in addition to having Figure 3 In addition to the first elastic sealing part 111 and the second elastic sealing part 131 similar to the embodiment shown in the figure, a groove structure 234 is also provided. The groove structure 234 is provided on the inner surface of the door part 130, and the opening of the groove structure 234 is provided toward the door frame part 110. In addition, the second elastic sealing part 131 is provided on the bottom wall of the groove structure 234. Therefore, the groove structure 234 can not only serve as a structure for strengthening the door plate of the door part 130, but also further increase the degree of tortuosity for liquid to enter, making it more difficult for liquid to enter.

[0057] Further preferably, when the door portion 130 and the door frame portion 110 are closed, the first elastic sealing portion 111 is also sealed and connected to the inner side wall of the groove structure 234. That is, the outer periphery of the sealing portion 113 of the first elastic sealing portion 111 is interference-fitted with the side wall of the groove structure 234 to achieve sealing, so that another sealing is added on the basis of the sealing between the first elastic sealing portion 111 and the second elastic sealing portion 131, further ensuring redundancy in preventing leakage.

[0058] In addition, as a preferred embodiment, the sealing performance can be improved by improving the degree of locking between the door portion 130 and the door frame portion 110. Figure 6 The door portion 130 is provided with a locking device 135, and the door frame portion 110 is provided with a matching device 116 matching with the locking device 135, and the number of the matching devices 116 corresponds to the number of the locking devices 135. Among them, a plurality of locking devices 135 are arranged at intervals along the height direction of the door portion 130. And the number of the locking devices 135 is at least four. That is, the number of the locking devices 135 is four, five, six, seven, etc., and the more the number, the higher the degree of locking between the door portion 130 and the door frame portion 110.

[0059] The second aspect of the present invention provides a container 10, which includes the door sealing structure of the first aspect. Figure 1The door 12 of the container 10 includes a door portion 130 , and the body 11 of the container 10 includes a door frame portion 110 .

[0060] The container 10 according to the present invention has a technical effect similar to that of the above-mentioned door sealing structure.

[0061] The container 10 is preferably constructed as an energy storage container, in particular a flat cabinet door energy storage container. That is, the door structure may be a flat cabinet door for opening and closing an energy storage cabinet.

[0062] As an optional embodiment, a stepped water retaining structure can be provided at the threshold of the box body 11 of the container 10 to further increase the difficulty of liquid infiltration. Exemplarily, the box body 11 includes a chassis structure 13, and since the first elastic sealing portion 111 and the second elastic sealing portion 131 are preferably configured as an annular continuous shape around the doorway. Therefore, the first bending portion 114 and the first flange 115 at the end thereof, the second bending portion 132 and the second flange 133 at the end thereof are also preferably configured as a circumferential annular continuous shape around the doorway. In other words, the side of the chassis structure 13 also has a first bending portion 114.

[0063] The first flange 115 located at the bottom frame structure 13 extends downward, and the upper surface of the first bent portion 114 located at the bottom frame structure 13 is higher than the first elastic sealing portion 111 and the second elastic sealing portion 131 located at the bottom frame structure 13. In addition, the upper surface of the bottom frame structure 13 is higher than the upper surface of the first bent portion 114 located at the bottom frame structure 13. Thus, a two-step stepped water retaining structure is formed. Preferably, as Figure 4 , Figure 5 and Figure 6 As shown, the upper surface of the base frame structure 13 is provided with a water retaining rib 14, which preferably extends along the width direction of the doorway or door panel, thereby further increasing the water retaining step and improving the waterproof capability.
