[0041] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0042] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] Referring to Figure 1, this application provides a container, including a folding door 100 and a container body 200. The folding door 100 includes a door body 10 and a door frame 20, and the door frame 20 is connected to the container body 200.

[0044] The enclosure 200 has an opening, and a folding door 100 is connected to the opening of the enclosure 200. The folding door 100 is suitable for closing and opening the enclosure 200. In the first state, the folding door 100 seals the enclosure 200. In the second state, the folding door 100 is open, and the enclosure 200 is exposed.

[0045] The material of the enclosure 200 can be stainless steel, fiberglass, aluminum alloy, steel-aluminum alloy, etc., without restriction.

[0046] The folding door 100 is installed to allow for the opening and closing of the container, in order to meet the usage requirements of the container.

[0047] In one embodiment, the door frame 20 and the container body 200 are integrated into one unit. That is, the door frame 20 and the container body 200 are a single structure, which helps to improve the space utilization rate of the container.

[0048] The extension direction of the first beam 21 of the door frame 20 is the first direction, and the extension direction of the column 22 of the door frame 20 is the second direction. The first direction and the second direction are perpendicular.

[0049] Referring to Figure 1, this application provides a door body 10, which includes a first door panel 11 and a second door panel 12. The first door panel 11 is adapted to be rotatably connected to the first beam 21 of the door frame 20, and the second door panel 12 is rotatably connected to the end of the first door panel 11 away from the first beam 21. In a first state, the first door panel 11 and the second door panel 12 have a first included angle, and both the first door panel 11 and the second door panel 12 are adapted to be connected to the door frame 20 and close the door frame 20. In a second state, the first door panel 11 and the second door panel 12 have a second included angle, and the second door panel 12 is spaced from the door frame 20. The first included angle is greater than the second included angle. During the process of switching from the first state to the second state, the end of the second door panel 12 close to the first door panel 11 moves away from the door frame 20, and the end of the second door panel 12 away from the first door panel 11 moves toward the first beam 21.

[0050] The first door panel 11 and the second door panel 12 can be made of solid wood, metal, MDF, etc. Specifically, the metal panel can be stainless steel or aluminum alloy, without limitation. Specifically, the first door panel 11 and the second door panel 12 can be formed by rectangular tubes forming a frame and then filling it with sheet metal parts, so that the door body 10 can reduce the weight of the door panel to the greatest extent while ensuring structural strength, thus saving space and weight.

[0051] Optionally, the second door panel 12 can be rotatably connected to the end of the first door panel 11 away from the first beam 21 by means of pin connection, sleeve connection, roller connection, cycloidal connection, gear connection, universal joint connection, etc., without limitation.

[0052] Optionally, the first door panel 11 and the second door panel 12 can be a single sub-door panel or multiple sub-door panels connected together in the first direction. The connection method between two adjacent sub-door panels can be screwed, welded, glued, etc., without restriction.

[0053] The first included angle is the angle between the first door panel 11 and the second door panel 12 when both the first door panel 11 and the second door panel 12 are connected to the door frame 20. Preferably, the first included angle can be 180°, that is, in the first state, the first door panel 11 and the second door panel 12 extend along a straight line and close the door frame 20.

[0054] The second included angle is the included angle between the first door panel 11 and the second door panel 12 when there is a gap between the second door panel 12 and the door frame 20.

[0055] Optionally, the door body 10 also includes a door lever lock 13. The door lever lock 13 is located at the end of the first door panel 11 near the column 22. The door lever lock 13 includes a connecting rod, a lock cover, and a lock head. When the connecting rod is pulled or pushed, the lock head performs a corresponding action to lock and unlock the door body 10. The lock cover cooperates with the connecting rod to protect the internal structure of the door lever lock 13.

[0056] The door 10 of this application achieves the closing and opening of the door frame 20 by setting a first door panel 11 and a second door panel 12 that switch between a first state and a second state. During the process of switching from the first state to the second state, the second door panel 12 moves toward the first beam 21 to reduce the included angle between the first door panel 11 and the second door panel 12, so that the door 10 is in a vertically folding form. Compared with the horizontally folding form, the door 10 of this application does not require an additional vertical beam structure. After the door 10 is applied inside the container, the space utilization rate inside the container can be increased. In the second state, the second door panel 12 of the door 10 of this application is spaced apart from the door frame 20, so that the door frame 20 can be fully opened, which is conducive to the entry and exit of products.

[0057] Referring to Figure 2, in one embodiment, in the second state, the second door panel 12 is disposed on the side of the first door panel 11 facing the ground. That is, during the process of the door body 10 opening to the door frame 20, the first door panel 11 and the second door panel 12 move away from the ground, and the second door panel 12 is located on the side of the first door panel 11 facing the ground. The door body 10 is in a vertically folded state. In the second state, the first door panel 11 covers the second door panel 12, which achieves preliminary waterproofing in terms of structure.

[0058] Referring to Figures 1 and 2, in one embodiment, the first door panel 11 includes a first end 111 and a second end 112 opposite to each other. The first end 111 is adapted to be rotatably connected to the first beam 21. The second door panel 12 includes a third end 121 and a fourth end 122 opposite to each other. The second end 112 is rotatably connected to the third end 121. The door body 10 also includes a first hinge 14, and the first door panel 11 and the second door panel 12 are connected by the first hinge 14.

[0059] There can be multiple first hinges 14, which are spaced apart. The connection between the first hinge 14 and the second end 112 and the third end 121 can be by screw connection.

[0060] Referring to Figure 1, optionally, the door body 10 also includes a second hinge 15. The first end 111 and the first beam 21 are rotatably connected through the second hinge 15. There can be multiple second hinges 15, which are spaced apart on the first beam 21 so that the first door panel 11 can be rotatably connected to the first beam 21.

[0061] By setting the first hinge 14 and the second hinge 15, the first door panel 11 is rotatably connected to the first beam 21, and the second door panel 12 is rotatably connected to the first door panel 11, so that the door body 10 can smoothly switch between the first state and the second state.

[0062] Referring to Figures 2 and 3, in one embodiment, the door body 10 further includes a first adhesive strip 16, which is disposed at the connection between the first door panel 11 and the second door panel 12, and extends along the extension direction of the first beam 21.

[0063] The material of the first adhesive strip 16 can be polyurethane, epoxy resin, polyethylene, silicone, rubber, etc., without restriction.

[0064] There may be two first adhesive strips 16, which are respectively set at the connection point of the second end 112 and the third end 121 near the door frame 20 and at the connection point of the second end 112 and the third end 121 away from the door frame 20.

[0065] Optionally, a connecting part is provided at the connection between the first door panel 11 and the second door panel 12. The connecting part has a receiving hole. The connecting part is located at the end of the second end 112 and the third end 121 in the first direction and connects the second end 112 and the third end 121. The two ends of the first adhesive strip 16 are respectively received in the receiving hole, and the receiving hole is filled with glue to ensure the waterproof effect and the installation reliability of the first adhesive strip 16.

[0066] Optionally, rain guards are also provided at the two ends of the door body 10 extending in the second direction. The rain guards can be connected to the door body 10 by means of adhesive bonding, snap-fitting, etc., without limitation. The rain guards provide initial protection against direct rainwater penetration into the container during heavy rain outdoors, and also prevent the sealing effect of the remaining rubber strips of the door body 10 from failing.

[0067] A first adhesive strip 16 is provided at the connection between the second end 112 and the third end 121 to achieve waterproofing at the connection between the first door panel 11 and the second door panel 12.

[0068] In one embodiment, the first adhesive strip 16 is a hollow structure. The hollow structure of the first adhesive strip 16 has a large compression margin, which enables it to maintain good waterproof sealing when the first door panel 11 and the second door panel 12 switch between the first state and the second state, thereby extending the service life of the door 10.

[0069] In one embodiment, the distance from the first end 111 to the second end 112 is h1, and the distance from the third end 121 to the fourth end 122 is h2, satisfying: 1.45≤h1 / h2≤1.55.

[0070] Optionally, h1 / h2 can be 1.45, 1.48, 1.5, 1.52, 155, etc., without restriction. Specifically, h1 is 1700mm and h2 is 1130mm. When h1 / h2 > 1.55, the size ratio of the first door panel 11 to the second door panel 12 is too large. In the second state, after the second door panel 12 is opened, the space reserved in the second direction of the container is small, which is not conducive to the handling of equipment inside the container. When h1 / h2 < 1.45, the size ratio of the first door panel 11 to the second door panel 12 is too small. In the second state, the fourth end 122 of the second door panel 12 may extend into the container, affecting the components of the container. When 1.45 ≤ h1 / h2 ≤ 1.55, the second door panel 12 can avoid the other components of the container, and sufficient operating space can be reserved when the container is open.

[0071] h1 can be considered as the length of the first door panel 11, and h2 can be considered as the length of the second door panel 12. The ratio of the first door panel 11 to the second door panel 12 is limited so that during the switching between the first state and the second state, the second door panel 12 can avoid other components of the container, such as the hydraulic rod 24 and the tie rod 23, to prevent the second door panel 12 from interfering with other components.

[0072] In one embodiment, in the second state, the angle between the first door panel 11 and the post 22 of the door frame 20 is a1, which satisfies: 100°≤a1≤110°.

[0073] a1 can be 100°, 103°, 105°, 108°, 110°, etc., without restriction.

[0074] Setting a1 limits the angle between the first door panel 11 and the column 22 when the container is fully opened, so that the first door panel 11 can be fully opened in the second state, and at the same time drive the second door panel 12, so that the container can be fully opened. Meanwhile, the first door panel 11 and the second door panel 12 can also avoid the components inside the container, which is conducive to improving the space utilization rate inside the container.

[0075] In one embodiment, the second included angle is a2, which satisfies: 10°≤a2≤20°.

[0076] a2 can be 10°, 12°, 15°, 18°, 20°, etc., without restriction.

[0077] In the second state, the included angle a2 between the first door panel 11 and the second door panel 12 is limited, and the size ratio between the first door panel 11 and the second door panel 12 is also limited, so that when the door body 10 opens the door frame 20, the fourth end 122 of the second door panel 12 is closer to the door frame 20 than the second end 112273 of the first door panel 11, and the fourth end 122 can be as far away from the ground as possible, which facilitates the movement of the device inside the container.

[0078] Referring to Figure 1, this application provides a folding door 100, including a door frame 20 and a door body 10 as described in any of the aforementioned embodiments. The door frame 20 includes a first beam 21 and a column 22. The first beam 21 is connected to the column 22, and the first door panel 11 is rotatably connected to the first beam 21.

[0079] Optionally, the door frame 20 is composed of multiple rectangular tubes, which can be connected by welding, screwing, etc.

[0080] Optionally, column 22 can be a first column or a second column, and one end of the first beam 21 is connected to the end of the first column away from the ground, while the other end of the first beam 21 is connected to the end of the second column away from the ground. Column 22 and the first beam 21 can be an integral structure or a separate structure, without limitation.

[0081] In the first state, the folding door 100 seals the container body 200. In the second state, the folding door 100 opens the container body 200 in an up-and-down folding state. During the transition from the first state to the second state, the second door panel 12 moves toward the first beam 21 to reduce the angle between the first door panel 11 and the second door panel 12, so that the door body 10 is in an up-and-down folding form. Compared with the left-and-right folding form, the door body 10 of this application does not need to be provided with an additional vertical beam structure, which can increase the space utilization rate inside the container after the door body 10 is applied inside the container.

[0082] Referring to Figures 2 and 3, in one embodiment, the folding door 100 further includes a pull rod 23, one end of which is rotatably connected to the first beam 21, and the other end of which is rotatably connected to the second door panel 12.

[0083] The tie rod 23 is a component with a certain structural strength. The tie rod 23 can be made of stainless steel, aluminum alloy, high-strength plastic, etc., without any restrictions.

[0084] Optionally, there are two pull rods 23, which are set at the two ends of the first beam 21 in the first direction, so that the force exerted by the pull rods 23 on the second door panel 12 can be symmetrical in the first direction, which is beneficial to the opening of the folding door 100.

[0085] During the transition from the first state to the second state, the lever 23 exerts a pulling force on the second door panel 12 due to its movement, causing the second door panel 12 to fold along with the movement of the first door panel 11. When the first door panel 11 moves to the top, the second door panel 12 is also pulled to the top by the lever 23, thereby realizing the folding action of the door 10.

[0086] Referring to Figure 3, in one embodiment, the folding door 100 further includes a first fixing seat 231 and a second fixing seat 232. The first fixing seat 231 is disposed on the first beam 21, and the second fixing seat 232 is disposed on the second door panel 12. One end of the pull rod 23 is rotatably connected to the first fixing seat 231, and the other end of the pull rod 23 is rotatably connected to the second fixing seat 232.

[0087] The connection method between the pull rod 23 and the first fixed seat 231 can be screwed, snap-fit, etc. Specifically, the first fixed seat 231 may include a base plate and a fixing part. Two fixing parts are arranged opposite each other on the base plate to form a receiving space. The fixing part has a first connecting hole, the base also has a second connecting hole, and the pull rod 23 has a third connecting hole. When the pull rod 23 is connected to the first fixed seat 231, the third connecting hole and the first connecting hole are correspondingly arranged, and bolts are provided to pass through the first connecting hole and the third connecting hole. At the same time, bolts are provided to pass through the second mounting hole to fix the first fixed seat 231 and the first beam 21. The first fixed seat 231 can be a metal component, a high-strength plastic component, etc., without limitation. Optionally, there are two first fixed seats 231, which are correspondingly arranged at the two ends of the first beam 21 in the first direction.

[0088] Optionally, the first door panel 11 is connected to the end of the first fixed base 231 furthest from the ground in the first direction, and the pull rod 23 is connected to the end of the first fixed base 231 closest to the ground in the first direction. Connecting the pull rod 23 and the first door panel 11 to the same first fixed base 231 reduces the number of connecting parts while ensuring connection strength.

[0089] The second fixing seat 232 has multiple threaded holes. Specifically, multiple countersunk bolts are used to fix the pull rod 23 to the second fixing seat 232. Optionally, there are two second fixing seats 232, which are respectively set at the ends of the second door panel 12 in the first direction.

[0090] Using the first fixing seat 231 and the second fixing seat 232 to fix both ends of the tie rod 23 helps to ensure the reliability and safety of the tie rod 23 under force.

[0091] Referring to Figure 3, in one embodiment, the folding door 100 further includes a hydraulic rod 24, one end of which is rotatably connected to the column 22, and the other end of which is rotatably connected to the first door panel 11.

[0092] Optionally, the hydraulic rod 24 can be manually driven or electrically driven. Specifically, the folding door 100 also includes a motor, which is electrically connected to the hydraulic rod 24 to enable the hydraulic rod 24 to be electrically driven, allowing the folding door 100 to fold automatically. Using the electrically driven hydraulic rod 24 to automatically open or close the folding door 100 is safer and less strenuous. The hydraulic rod 24 works in conjunction with the door lever lock 13; after the door lever lock 13 is activated, the hydraulic rod 24 opens the folding door 100.

[0093] The hydraulic rod 24, the pull rod 23, the first door panel 11 and the second door panel 12 form a four-bar linkage to realize the folding action of the second door panel 12. Compared with the folding door 100 that uses a sliding rail to limit the trajectory of the second door panel 12, this application uses a four-bar linkage to limit the trajectory of the second door panel 12, so that the folding door 100 can be fully opened, which is more conducive to the entry and exit of products from the container.

[0094] Optionally, there are two hydraulic rods 24, which are connected to the first column 22 and the second column 22 respectively.

[0095] Specifically, when transitioning from the first state to the second state, the hydraulic rod 24 extends out. At this time, the hydraulic rod 24 is at a certain angle to the second direction, and the force of the hydraulic rod 24 is mainly used to overcome the gravity of the door 10. The door 10 is slowly pushed out. During the pushing process, due to the pulling force generated by the movement of the pull rod 23 on the second door panel 12, the second door panel 12 folds along with the movement of the first door panel 11. When the first door panel 11 moves to the top, the second door panel 12 is also pulled to the top by the pull rod 23, thereby realizing the folding action of the door 10 to complete the full opening of the folding door 100.

[0096] Referring to Figure 3, in one embodiment, the folding door 100 further includes a first support member 241 and a second support member 242. The first support member 241 is disposed on the column 22, and the second support member 242 is disposed on the first door panel 11. One end of the hydraulic rod 24 is connected to the first support member 241, and the other end of the hydraulic rod 24 is connected to the second support member 242.

[0097] The connection methods between the first support member 241 and the column 22, and between the second support member 242 and the first door panel 11, can be welding, bonding, screwing, etc., without restriction. The first support member 241 and the second support member 242 can be metal components, high-strength plastic components, etc.

[0098] Using the first support member 241 and the second support member 242 to connect the two ends of the hydraulic rod 24 helps to ensure the working reliability and safety of the hydraulic rod 24.

[0099] Referring to Figure 3, in one embodiment, in the projection of the folding door 100 in the extension direction of the first beam 21, the length of the pull rod 23 is d1, the distance from the connection point of the first door panel 11 and the first beam 21 to the connection point of the pull rod 23 and the first beam 21 is d2, the distance from the connection point of the first door panel 11 and the second door panel 12 to the connection point of the pull rod 23 and the second door panel 12 is d3, and the dimension from the first end 111 to the second end 112273 of the first door panel 11 is h1, satisfying: d1+d2>h1+d3.

[0100] Specifically, when the first door panel 11 and the pull rod 23 are set in the same first fixed seat 231, d2 can be the distance from the pivot of the first door panel 11 and the first fixed seat 231 to the pivot of the pull rod 23 and the first fixed seat 231.

[0101] When d1+d2>h1+d3, the pulling force generated by the movement of the lever 23 on the second door panel 12 is sufficient to make the second door panel 12 fold along with the movement of the first door panel 11, thus realizing the folding action of the door 10.

[0102] Referring to Figure 4, in one embodiment, the door body 10 further includes a second adhesive strip 25, which is used to be disposed at the junction of the first door panel 11 and the first beam 21, and the second adhesive strip 25 extends along the extension direction of the first beam 21.

[0103] The material of the second adhesive strip 25 can be polyurethane, epoxy resin, polyethylene, silicone, rubber, etc., without restriction.

[0104] Optionally, the folding door 100 also includes a connector 251. The connector 251 is disposed on the side of the first end 111 of the first door panel 11 facing the door frame 20. The connector 251 is L-shaped, with one end connected to the first door panel 11 and the other end connected to the second adhesive strip 25. The connection method between the connector 251 and the second adhesive strip 25 can be a snap-fit ​​connection.

[0105] Using connector 251 in conjunction with the first door panel 11 makes the installation of the second adhesive strip 25 more secure, which helps to extend the service life of the second adhesive strip 25.

[0106] Referring to Figure 4, in one embodiment, the door body 10 further includes a drainage component 27, which is disposed at the junction of the first door panel 11 and the first beam 21. The drainage component 27 has a drainage groove 271, the opening of which faces the second rubber strip 25. Both the drainage component 27 and the drainage groove 271 extend along the extension direction of the first beam 21.

[0107] The drainage component 27 includes a first section 272, a second section 273, and a third section 274 connected in sequence. The first section 272 and the third section 274 extend along a second direction, while the second section 273 extends along a first direction. The drainage channel 271 has no sidewalls at both ends in the first direction, allowing for a through-flow design so that water can be discharged from both sides of the first direction to the outside of the folding door 100. The drainage component 27 can be made of aluminum-plastic pipe, polyvinyl chloride pipe, polyethylene pipe, etc., without limitation. The bottom wall of the drainage channel 271 can be arc-shaped, rectangular, etc., without limitation.

[0108] The drainage component 27 encloses and forms a drainage channel 271, allowing water to drain out of the folding door 100. At the same time, it can also prevent water from continuing to seep into the ground from inside the folding door 100, thereby damaging the sealing and service life of the folding door 100.

[0109] Referring to Figure 4, in one embodiment, the door body 10 further includes a water guide plate 26, which is disposed between the second rubber strip 25 and the drainage member 27. The water guide plate 26 is adapted to guide the water seeping into the second rubber strip 25 into the drainage groove 271.

[0110] The water guide plate 26 is connected to the first door panel 11. The water guide plate 26 is closer to the ground than the second adhesive strip 25, and there is an angle between the water guide plate 26 and the first door panel 11. The water guide plate 26 extends in the direction closest to the ground. The water guide plate 26 can be a plastic component, stainless steel component, aluminum alloy component, etc. The connection method between the water guide plate 26 and the first door panel 11 can be welding, bonding, screwing, etc., without limitation. There can be multiple water guide plates 26, which are spaced apart in the first direction. When there is only one water guide plate 26, it extends in the first direction. After the second adhesive strip 25 fails or leaks, the water guide plate 26 mainly guides the leaking water, allowing it to enter the drain groove 271 without affecting the other components of the folding door 100.

[0111] When the second rubber strip 25 fails or leaks, the water flows through the water guide plate 26 into the drainage channel 271 formed by the drainage component 27. The top of the drainage channel 271 is an open structure, which can be used to drain water to the outside of the container in the first direction, which helps to improve the waterproof effect of the folding door 100 and the container.

[0112] This application provides an energy storage system, including a battery device and a container as described in any of the foregoing embodiments, wherein the battery device is housed within the container. Multiple battery devices may be housed within the container. The energy storage system of this application has good sealing performance, making it more suitable for outdoor or humid environments.
