[0089] As Figures 1 to 3 and Figure 8 and Figure 9 shown, a first aspect of the present invention provides a container door 100 for an energy storage container 1, and in particular, it can be used for a marine energy storage container 1. The container door 100 includes a door panel 110, a sill 121, and a support assembly 130. The door panel 110 extends in a first direction perpendicular to the thickness direction and the height direction, and the door panel 110 is used to be pivotally connected to the box body 20 of the energy storage container 1. The sill 121 is located below the door panel 110, and the sill 121 includes a sill main body 121a and a support portion 121b, and the support portion 121b protrudes from the sill main body 121a in the thickness direction. The support assembly 130 includes a mounting member 133, a rolling member 132, and a connecting member 131. The mounting member 133 includes a mounting plate 133a extending in the first direction and the height direction and a support plate 133b extending in the thickness direction and the height direction. Both sides of the support plate 133b in the thickness direction are fixedly connected to the door panel 110 and the mounting plate 133a respectively. The connecting member 131 is fixedly connected to the mounting plate 133a of the mounting member 133 in the thickness direction. The rolling member 132 is rotatably connected to the mounting member 133, and the rolling member 132 is rollably abutted against the support portion 121b of the sill 121.

[0090] According to the container door 100 of the present invention, its door panel 110 is stably supported on the support portion 121b of the sill 121 by the support assembly 130, preventing the container door 100 from tilting, deforming, or losing corners during use, extending the service life of the hinge 150 that hinges the fire door to the box body 20 or the door frame 120, ensuring the matching accuracy between the door lock 113 and the box body 20 or the door frame 120, reducing the shaking of the container door 100 in a bumpy environment, and improving the stability. In addition, the support assembly 130 has high strength and stable structure by itself, and at the same time, the setting of the rolling member 132 ensures that the container door 100 can be opened and closed smoothly.

[0091] It should be noted that the direction of the container door is for the container door installed on the energy storage container. Of course, for this container door product, it can exist in a state where it is not installed on the energy storage container. The "first direction" is the width direction of the container door.

[0092] The container door can be installed on the side wall of the energy storage container or on the end of the energy storage container. It can be installed on the front end of the energy storage container or on the rear end of the energy storage container. The "second direction" is the width direction of the container. When the container door is installed on the end of the energy storage container, the "second direction" is parallel to the "first direction". When the container door is installed on the side wall of the energy storage container 1, the "second direction" is perpendicular to the "first direction" and parallel to the "thickness direction" of the container door. The "height direction" of the container door is parallel to the "height direction" of the energy storage container.

[0093] Taking the example where the container door 100 is installed on the rear end of the energy storage container 1 as an example, the "second direction" is parallel to the "first direction" and parallel to the width direction of the energy storage container 1.

[0094] Figures 1 to 3 A container door 100 is shown. The container door 100 is used for the energy storage container 1. The container door 100 may include a door panel 110, a door frame 120, a support assembly 130, a seal 140, and a door lock 113.

[0095] The door panel 110 extends in a first direction perpendicular to the thickness direction and the height direction. The door panel 110 is used to be pivotally connected to the box body 20 of the energy storage container 1.

[0096] The sill 121 is located below the door panel 110. The sill 121 includes a sill main body 121a and a support portion 121b. The support portion 121b protrudes from the sill main body 121a in the thickness direction. The support assembly 130 includes a mounting member 133, a rolling member 132, and a connecting member 131. The mounting member 133 includes a mounting plate 133a extending in the first direction and the height direction and a support plate 133b extending in the thickness direction and the height direction. Both sides of the support plate 133b in the thickness direction are fixedly connected to the door panel 110 and the mounting plate 133a respectively. The connecting member 131 can be fixedly connected to the mounting plate 133a of the mounting member 133 in the thickness direction via, for example, fasteners. The rolling member 132 is rotatably connected to the mounting member 133, and the rolling member 132 is rollingly abutted against the support portion 121b of the sill 121. The rolling member 132 can be configured as a roller.

[0097] Thus, the door panel 110 of the container door 100 is stably supported by the support assembly 130 on the support portion 121b of the sill 121, preventing the container door 100 from tilting, deforming, or losing corners during use, extending the service life of the hinge 150 that hinges the fire door to the box body 20 or the door frame 120, and ensuring the matching accuracy between the door lock 113 and the box body 20 or the door frame 120. In addition, the support assembly 130 has high strength and stable structure, and the setting of the rolling member 132 ensures the smooth opening and closing of the container door 100.

[0098] Reference Figure 1 and Figure 2 , the door panel 110 may include a door body 111 and a fireproof strengthening portion 112. The door body 111 is installed within the door frame 120, and the fireproof strengthening portion 112 may protrude from the door body 111 in the thickness direction. Thus, the fireproof performance and structural strength of the container door 100 are improved. One end of the mounting plate 133a of the mounting member 133 in the first direction may be connected to the fireproof strengthening portion 112. Thus, the structure is simple, the strength and stability of the mounting member 133 are improved, and further the strength and stability of the support assembly 130 are improved.

[0099] Reference Figure 1 , in some embodiments, the connecting member 131 may include a first flat plate and two limiting plates oppositely arranged in the first direction. The first flat plate is connected between the two limiting plates in the first direction. The first flat plate is fixedly connected to the mounting plate 133a of the mounting member 133 via, for example, fasteners. The rolling member 132 may be rotatably connected to the limiting plate of the mounting member 133 via a rotating shaft (such as a rotating pin), such that the movement of the rolling member 132 in the first direction is restricted between the two limiting plates. This structure is simple, easy to manufacture, and convenient to use.

[0100] Reference Figure 1 , in some embodiments, the support portion 121b of the sill 121 may include a second flat plate and two reinforcing plates oppositely arranged in the first direction. The second flat plate is arranged horizontally, and the second flat plate is connected between the two reinforcing plates in the first direction. The rolling member 132 is rollably abutted against the surface of the second flat plate of the support portion 121b of the sill 121. It can be understood that when the container door 100 is opened or closed, the rolling member 132 can rotate in addition to rolling on the second flat plate to facilitate the opening or closing of the container door 100.

[0101] In some embodiments, the door frame 120 may be fixedly connected to the box body 20 of the energy storage container. The door panel ********** is pivotally connected to the door frame 120, and thus pivotally connected to the box body 20 of the energy storage container 1.

[0102] In some embodiments, such as Figure 1 andFigure 2 As shown, the container door 100 can be a single-opening door structure. The door frame 120 can include a sill 121, a first door post 122, a second door post 123, and a lintel 124. The sill 121 and the lintel 124 extend in the width direction and are disposed opposite to each other in the height direction. The first door post 122 and the second door post 123 extend in the height direction and are disposed opposite to each other in a first direction. The bottom ends of the first door post 122 and the second door post 123 can both be connected to the sill 121 in the height direction, and the top ends of the first door post 122 and the second door post 123 can both be connected to the lintel 124 in the height direction.

[0103] One end of the door panel 110 in the first direction can be locked to the door frame 120 via a door lock 113, for example, locked to the first door post 122. That is to say, the container door 100 can be opened or closed by operating the door lock 113. The door lock 113 can be provided with a handle to facilitate opening the container door 100, or to facilitate locking or unlocking. The other end of the door panel 110 in the first direction, which is different from this end, can be hinged to the door frame 120 via a hinge 150, for example, hinged to the second door post 123. In other words, the container door 100 can pivot around the second door post 123 to open or close.

[0104] Of course, if necessary and / or desired, the relative positions of the door lock 113 and the hinge 150 in the first direction can be interchanged.

[0105] In some embodiments, the container door 100 can include at least two door locks 113. The at least two door locks 113 are spaced apart in the height direction so as to be able to lock one end of the door panel 110 in the first direction to the box body 20, for example, can be locked to the door frame 120, and can be locked to the first door post 122 of the door frame 120. Thus, two-point or multi-point locking of the door lock 113 can be achieved, which can provide greater pressure, so that the sealing strip between the door panel 110 and, for example, the door frame 120 is pressed more tightly, thereby enhancing the sealing performance.

[0106] Of course, if necessary and / or desired, the container door 100 may not include the first door post 122 and / or the second door post 123. At this time, the container door 100 can be directly locked to the end plate of the container via the door lock 113.

[0107] Reference Figure 3 , the seal 140 of the container door 100 can connect the door panel 110 and the sill 121 to improve the waterproof performance of the container door 100.

[0108] In some embodiments, the threshold 121 may include a first vertical section 121c, a first horizontal section 121d, a second vertical section 121e, and a second horizontal section 121f. The first horizontal section 121d may be connected between the top of the first vertical section 121c and the top of the second vertical section 121e. The second horizontal section 121f may be connected to the bottom of the second vertical section 121e and extend away from the first vertical section 121c. Thus, the threshold 121 has high structural strength and is more stable.

[0109] The seal 140 (such as a sealing strip) may be connected to the first vertical section 121c and the door panel 110. Thus, the connection between the seal 140 and the threshold 121 is made more firm, and the sealing performance is improved.

[0110] In some embodiments, the top of the seal 140 may be lower than the top of the threshold 121. Thus, liquid (such as rainwater) can gather in the groove at the bottom of the door panel 110 due to gravity and flow out of the box body 20 as the door is opened, reducing the risk of water accumulation inside the box and further improving the waterproof performance of the container door 100.

[0111] Of course, if desired and / or wished, as Figure 8 shown, the container door 100 may also be of a double - door structure. The two door panels 110 are arranged along a first direction. The outer ends of the two door panels 110, which are arranged in opposite directions along the first direction, are used to be pivotally connected to the box body 20 of the energy - storage container 1.

[0112] The second aspect of the present utility model provides an energy - storage container 1, including the container door 100 according to the first aspect of the present utility model and a chassis 10. The chassis 10 includes a bottom sealing plate 11 and a bottom cross - beam 12, and the bottom sealing plate 11 is located above the bottom cross - beam 12. The bottom sealing plate 11 and the bottom cross - beam 12 do not contact each other in the height direction.

[0113] The energy - storage container 1 according to the second aspect of the present utility model can achieve technical effects similar to those of the container door 100 in the above - mentioned first aspect.

[0114] It can be understood that the energy - storage container 1 according to the second aspect of the present utility model includes all the technical features and effects of the container door 100 according to the first aspect of the present utility model. Additionally, the non - contact between the bottom sealing plate 11 and the bottom cross - beam 12 in the height direction creates an air layer between the bottom sealing plate 11 and the bottom cross - beam 12, improving the fire - proof performance and heat - preservation performance of the energy - storage container 1.

[0115] The chassis 10 may include a bottom sealing plate 11, a bottom cross - beam 12, and two bottom side beams 13 that are oppositely arranged along a second direction. Refer to Figure 6, the bottom side beam 13 can be configured as an H-shaped I-beam steel structure, thereby improving rigidity and strength to cope with the weight increase of the energy storage container 1 caused by the increase in battery capacity described below.

[0116] Optionally, a fireproof layer can be provided between the chassis 10 and the bottom cross beam 12, thereby further improving the fireproof performance of the energy storage container 1. The fireproof layer can be composed of a fireproof blanket with a fireproof rating of above A60. Since the bottom sealing plate 11 and the bottom cross beam 12 do not contact each other in the height direction, the fireproof blanket can be completely laid between them without being truncated.

[0117] Reference Figure 5 , the bottom sealing plate 11 can include a first horizontal plate 11a, a second horizontal plate 11b, and a connecting plate 11c. The first horizontal plate 11a and the second horizontal plate 11b are spaced apart in the height direction. The first horizontal plate 11a is located above the second horizontal plate 11b. The connecting plate 11c can be connected between the first horizontal plate 11a and the second horizontal plate 11b in the height direction. Thereby, the stiffness of the bottom sealing plate 11 is increased, and even when the bottom sealing plate 11 and the bottom cross beam 12 do not contact or connect in the height direction, the bottom sealing plate 11 still has sufficient stiffness. The above shape of the bottom sealing plate 11 can be formed by stamping on a flat plate.

[0118] Optionally, reference Figure 4 , the energy storage container 1 can include a box body 20, a partition 21, a liquid cooling unit 22, and a cold fluid pipeline. The partition 21 is arranged along the width direction of the energy storage container 1. The interior of the box body 20 is divided into an equipment compartment and a battery compartment arranged along the length direction of the energy storage container 1 by the partition 21. The liquid cooling unit 22 is arranged in the equipment compartment. The cold fluid pipeline is connected to the liquid cooling unit 22 in a circulating manner and extends into the battery compartment, specifically, it can extend to each battery pack respectively. Thereby, the cold fluid can circulate through the battery pack to cool the battery pack. The utility model adopts a liquid cooling method to cool the battery compartment, so that the space in the battery compartment can be more compact and more batteries can be carried.
