[0073] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

[0074] The first aspect of this utility model provides a sealing door assembly 100. (See reference...) Figures 1 to 5 The sealing door assembly 100 includes a door frame 110, a door body 120, a seal, a pre-locking assembly 130, and a locking mechanism. The door frame 110 includes a first beam 111, a second beam 112, a third beam 113, and a fourth beam 114, wherein the first beam 111 and the second beam 112 extend vertically and are spaced apart, and the third beam 113 and the fourth beam 114 connect the ends of the first beam 111 and the second beam 112. The door body 120 is pivotally mounted on the first beam 111. The seal is disposed around the perimeter of the door frame 110 and / or the perimeter of the door body 120, and when the door body 120 is closed, the seal connects between the door frame 110 and the door body 120. The pre-locking assembly 130 includes a lock seat portion 131 and a locking portion 134. The lock seat portion 131 is disposed on the third beam 113 and the fourth beam 114, and the locking portion 134 is movably disposed on the door body 120. The pre-locking assembly 130 is used to initially lock the door body 120 to the door frame 110. The secondary locking assembly is at least partially disposed on at least one of the first beam 111, the second beam 112, the third beam 113, and the fourth beam 114. The secondary locking assembly is used to lock the door body 120 to the door frame 110 a second time after the initial locking.

[0075] According to the sealing door structure of this application, the double locking mechanism enables the door structure to not only have waterproof sealing but also airtightness.

[0076] Specifically, refer to Figure 2 and Figure 3 The door frame 110 has a folded edge 115 extending in a first direction D1 and forming a first groove 116 around its periphery. The door body 120 has a flanged edge 124 extending in a second direction D2 and forming a second groove 125 around its periphery. A seal is disposed in the first groove 116 and the second groove 125. The second direction D2 is opposite to the first direction D1. When the sealing door assembly 100 is located in the container, the first direction D1 is towards the outside of the container, and the second direction D2 is towards the inside of the container.

[0077] The first beam 111, second beam 112, third beam 113, and fourth beam 114 of the door frame 110 may each have an inner beam 117 and an outer beam 118, wherein the inner beam 117 is located inside the outer beam 118 along the second direction D2. The two sides of the inner beam 117 are bent towards the first direction D1 to form the aforementioned folded edge portion 115, and the outer beam 118 is connected to the inner beam 117 and located between the two folded edge portions 115. Thus, the outer beam 118 and the folded edge portion 115 near the door body 120 form the aforementioned first groove 116.

[0078] The door body 120 includes an outer door panel 121, an inner door panel 122, and a back beam 123. The outer door panel 121 is connected to the side of the back beam 123 facing a first direction D1, and the inner door panel 122 is connected to the side of the back beam 123 facing a second direction D2. The back beam 123 is located around the perimeter of the door body 120, roughly forming the outline of the door body 120. The edge of the outer door panel 121 is bent towards the second direction D2 to form the aforementioned flange 124, thereby enclosing the weld of the back beam 123 internally and further reducing the risk of air leakage. Furthermore, the folded edge 115 of the door frame 110, near the side of the door body 120, is located between the flange 124 and the back beam 123. In other words, the flange 124 extends towards the first groove 116, and the folded edge 115 extends towards the second groove 125.

[0079] The sealing elements include a first sealing element 150 and a second sealing element 160. The first sealing element 150 is disposed in the first groove 116, and the second sealing element 160 is disposed in the second groove 125. When the door 120 is closed, the folded edge 115 is sealed to the second sealing element 160, and the flanged edge 124 is sealed to the first sealing element 150. This forms a double seal with high redundancy, significantly improving the airtightness.

[0080] The first seal 150 and / or the second seal 160 can be constructed as hollow structures to achieve greater elastic deformation, thereby enabling the formation of a seal with less effort. Alternatively, the first seal 150 and / or the second seal 160 can be constructed as solid structures to achieve higher airtightness.

[0081] The sealing door assembly 100 also includes a hinge assembly 170, which includes a hinge portion 171 and a lug portion 173. The door body 120 is hinged to the door frame 110 via the hinge assembly 170. The door body 120 is provided with the hinge portion 171, and the door frame 110 is provided with the lug portion 173. The lug portion 173 has hinge holes 174 / 274, and the hinge shaft 172 of the hinge portion 171 is provided in the hinge holes 174 / 274.

[0082] refer to Figure 4The locking part 134 can be configured as a locking rod; in other words, the pre-locking assembly 130 can be configured as a locking rod assembly. The locking part 134, or locking rod, includes a rod body 135 and a hook head 136. The hook head 136 is disposed at the end of the rod body 135 and offset relative to the rod body 135. The locking seat part 131 includes a base 132 and an actuating part 133. The actuating part 133 is spaced apart on the side of the base 132 along the first direction D1. When the locking rod rotates, the hook head 136 abuts against the actuating part 133. Therefore, using the hook-shaped pre-locking assembly 130 helps reduce resistance during operation, increases the locking space, and facilitates the formation of an initial seal.

[0083] In other alternative embodiments, the locking part 134 may also adopt other structures that can be connected to the lock seat part 131 to form an initial locking, such as a bolt or other component.

[0084] refer to Figure 5 The secondary locking assembly includes a fixed base, a locking part, and a locking fastening part. The fixed base is provided at least in one of the first beam 111, the second beam 112, the third beam 113, and the fourth beam 114. The locking part can be connected to the door body. The locking part is used to connect with the locking part and the fixed base to lock the locking part and the fixed base.

[0085] As an optional implementation, the secondary locking assembly includes a first locking mechanism 140. The first locking mechanism 140 includes a first fixed base 141, a first locking part 142, and a first locking part 143. The second beam 112, the third beam 113, and the fourth beam 114 are provided with the first fixed base 141. The first locking part 142 is fixedly connected to the door body 120, and the first locking part 143 is movably connected to the first locking part 142. When the door body 120 is closed, the first locking part 143 can rotate to connect with the first locking part 142. A lock slot is provided on the edge of the first locking part 142 near the door frame 110.

[0086] In this embodiment, the first locking part 143 includes a movable rod 144 and an operating member 145. One end of the movable rod 144 is pivotally connected to the first fixed base 141, and the other end is threaded. The operating member 145 is threadedly connected to the movable rod 144. When the first locking mechanism 140 is locked, the movable rod 144 rotates into the lock jaw, and the operating member 145 is located on the side of the first locking part 142 along the first direction D1. In an embodiment not shown, the first locking part 143 may also be a component with a wedge-shaped surface to form an interference fit with the first locking part 142.

[0087] In this embodiment, the first seal 150 can be constructed as a solid structure or a hollow structure, and the second seal 160 is constructed as a hollow structure. In this embodiment, after the door 120 is closed, it is initially locked using the pre-locking assembly 130. Then, the first locking mechanism 140 is locked. At this time, the hollow design of the second seal 160 near the hinge assembly 170 or near the first beam 111 has a large deformation, and its deformation can meet the sealing requirements. Therefore, this side does not need to be locked a second time. That is to say, in this embodiment, the hinge shaft 172 and the hinge hole 174 do not need to be displaced relative to each other, and the hinge hole 174 can be designed as a round hole.

[0088] refer to Figure 6 , Figure 7 , Figure 8 and Figure 9 The diagram illustrates another embodiment of the sealing door assembly 200. In this embodiment, the first seal 150 is constructed as a solid structure, and the portion of the second seal 260 near the first beam 111 is also constructed as a solid structure.

[0089] In this embodiment, since the second sealing element 260 at the first beam 111 is a solid structure with small deformation, the first locking mechanism 140 alone is insufficient to achieve a complete circumference seal of the door 120. Therefore, the first beam 111 is preferably provided with a second locking mechanism 240, which is different from the first locking mechanism 140 in the above embodiments. Figure 9 In this embodiment, the second locking mechanism 240 includes a second fixed base 241, a second locking part 242, and a second locking part 243. The second fixed base 241 is disposed on the first beam 111 and has a screw hole. The second locking part 242 and the second locking part 243 are movable parts, and the second locking part 243 is threadedly engaged with the second fixed base 241. In other words, the second locking part 242 can be completely removed.

[0090] In this embodiment, after the door 120 is closed, it is initially locked using the pre-locking assembly 130. Then, the locking mechanism near the hinge assembly 170 is locked, specifically the second locking mechanism 240. At this point, the door 130 near the hinge assembly 170, or the side near the first beam 111, is pressed down, while the door 130 near the second beam 112 tilts outwards. Then, the first locking mechanism 140 presses down the door 130 on the sides of the second beam 112, the third beam 113, and the fourth beam 114. In this embodiment, since the side near the hinge assembly 170 needs to be pressed down to achieve airtightness, the door 130 also needs a certain amount of displacement in the inward and outward directions at this location. Therefore, the hinge shaft 172 and the hinge hole 274 need relative displacement, and the hinge hole 274 is preferably designed as an oblong hole.

[0091] A second aspect of this application provides an energy storage container, which includes the sealing door assembly described in the first aspect.

[0092] The energy storage container according to this utility model has similar technical effects to the sealing door structure in the first aspect described above.
