[0042] See also Figures 1 to 4 The present application provides a mobile energy storage container, which includes: a frame 100 and a door assembly 200. A receiving space 140 for receiving an energy storage structure 300 is formed in the frame 100. The frame 100 includes an upper beam 110 and a lower beam 120 located on the same side of the receiving space 140. The upper beam 110 and the lower beam 120 are arranged at intervals up and down. The door assembly 200 includes a door frame 210 and a door body 220. The door frame 210 includes an upper door beam 211, a lower door beam 212 and two vertical beams 213, the upper end surface of the upper door beam 211 abuts and is connected to the upper side beam 110, and the lower end surface of the lower door beam 212 abuts and is connected to the lower side beam 120. The two vertical beams 213 are respectively located at the two ends of the upper door beam 211 and the lower door beam 212 to support the upper door beam 211 and the lower door beam 212. The door body 220 is arranged corresponding to the door frame 210. The door body 220 is rotatably connected to the vertical beam 213 so that the door body 220 can cover the door frame 210. The outer surfaces of the door body 220, the upper beam 110 and the lower beam 120 are surfaces facing outward relative to the receiving space 140. The door body has an open state and a closed state; when the door body is in the closed state, the orthographic projection of the outer surface of the door body 220 in the up-down direction is located inside the orthographic projection of the outer surfaces of the upper beam 110 and the lower beam 120; or, in the up-down direction, the orthographic projection of the outer surface of the door body 220 coincides with the orthographic projection of the outer surfaces of the upper beam 110 and the lower beam 120.

[0043] During the design and production process of the mobile energy storage container, the upper end surface of the upper door beam 211 is abutted against and connected to the upper side beam 110, and the lower end surface of the lower door beam 212 is abutted against and connected to the lower side beam 120. The door frame 210 is connected to the upper side beam 110 and the lower side beam 120, which can effectively improve the overall structural strength of the mobile energy storage container and ensure the impact resistance of the mobile energy storage container.

[0044] When the door is in a closed state, in the vertical direction, the orthographic projection of the outer surface of the door 220 is located inside the orthographic projection of the outer surface of the upper beam 110 and the lower beam 120. Or, in the vertical direction, the orthographic projection of the outer surface of the door 220 coincides with the orthographic projection of the outer surface of the upper beam 110 and the lower beam 120. While meeting the size requirements of the container, the distance from the periphery of the frame 100 to the center of the mobile energy storage container is increased, thereby increasing the effective volume of the mobile energy storage container and improving the space utilization of the mobile energy storage container.

[0045] See also Figures 1 to 4 In this embodiment, the mobile energy storage container includes a frame 100. The frame 100 includes an upper side beam 110, a lower side beam 120 and a column 130. The upper side beam 110 includes two upper longitudinal beams 111 and two upper cross beams 112. The two upper longitudinal beams 111 are arranged opposite to each other, and the two upper cross beams 112 are arranged opposite to each other. The two upper longitudinal beams 111 are respectively connected to the two ends of the two upper cross beams 112, so that the two upper longitudinal beams 111 and the two upper cross beams 112 are enclosed to form a rectangular structure.

[0046] The lower side beam 120 includes two lower longitudinal beams 121 and two lower cross beams 122. The two lower longitudinal beams 121 are arranged opposite to each other, and the two lower cross beams 122 are arranged opposite to each other. The two lower longitudinal beams 121 are respectively connected to the two ends of the two lower cross beams 122, so that the two lower longitudinal beams 121 and the two lower cross beams 122 are enclosed to form a rectangular structure.

[0047] The column 130 is located between the upper beam 110 and the lower beam 120 . The column 130 extends in the up-down direction to respectively abut and connect the vertices of the upper beam 110 and the lower beam 120 to support the upper beam 110 and the lower beam 120 .

[0049] See also Figure 1 , Figure 2 , Figures 4 to 6 In this embodiment, the door assembly 200 is located between the upper beam 110 and the lower beam 120 so as to be able to open and close the receiving space 140, thereby facilitating the installation, disassembly, use and maintenance of the energy storage structure 300.

[0051] See also Figure 1 , Figure 2 , Figure 4 , Figures 7 to 11 The door assembly 200 includes a door frame 210 and a door body 220. The door frame 210 includes an upper door beam 211, a lower door beam 212 and two vertical beams 213. The upper door beam 211 extends along the extension direction of the upper side beam 110. The lower door beam 212 extends along the extension direction of the lower side beam 120. The vertical beam 213 extends in the up-down direction to resist and support the upper door beam 211 and the lower door beam 212. The two vertical beams 213 are respectively arranged at both ends of the upper door beam 211 and the lower door beam 212.

[0052] The upper end surface of the upper door beam 211 of the door frame 210 abuts against and is connected to the upper side beam 110. The lower end surface of the lower door beam 212 abuts against and is connected to the lower side beam 120. It can increase the contact area between the door frame 210 and the upper side beam 110 and the lower side beam 120, thereby improving the structural strength of the mobile energy storage container and improving the impact resistance of the mobile energy storage container.

[0053] See also Figure 3 and Figure 4 In some embodiments, the upper end surface of the upper door beam 211 is welded to the upper side beam 110 to improve the structural strength of the door assembly 200 and the frame 100. The lower end surface of the lower door beam 212 is welded to the lower side beam 120 to improve the structural strength of the door assembly 200 and the frame 100. Because the size parameters of the container are determined, by embedding the door assembly 200 between the upper side beam 110 and the lower side beam 120, the spacing between the side walls of the container in the front-to-back direction and the left-to-right direction can be increased, thereby increasing the effective volume in the container, so that more energy storage structures 300 can be accommodated, and the space utilization efficiency of the mobile energy storage container is improved.

[0054] See also Figure 1 and Figure 2There are multiple door assemblies 200, and multiple door frames 210 are arranged in parallel along the extension direction of the upper side beam 110. The adjacent door frames 210 are tightly fitted together, so that the multiple door assemblies 200 can be combined to form the side wall of the mobile energy storage container, thereby increasing the structural strength and impact resistance of the side wall of the mobile energy storage container.

[0055] In some embodiments, the door assembly 200 is disposed between the upper longitudinal beam 111 and the lower longitudinal beam 121, so that a plurality of door assemblies 200 form two side walls in the transverse direction of the mobile energy storage container. In other embodiments, the door assembly 200 is disposed between the upper crossbeam 112 and the lower crossbeam 122, so that a plurality of door assemblies 200 form two side walls in the longitudinal direction of the mobile energy storage container. In other embodiments, the door assembly 200 is disposed between the upper longitudinal beam 111 and the lower longitudinal beam 121, and also between the upper crossbeam 112 and the lower crossbeam 122, so as to facilitate the opening and closing of the peripheral side of the mobile energy storage container.

[0056] In other embodiments, multiple door frames 210 are arranged in parallel, and the adjacent vertical beams 213 of any two adjacent door frames 210 are abutted and connected to improve the structural strength of the side wall of the mobile energy storage container. In other embodiments, the adjacent vertical beams 213 of any two adjacent door frames 210 are welded to improve the structural strength of the mobile energy storage container.

[0057] Fig.12 yes Fig.10 Enlarged view of the structure at E in the middle.

[0058] See also Figure 2 , Figures 7 to 12 In this embodiment, the door frame 210 is provided with an opening 214, and the outer wall of the door frame 210 is provided with a sealing plate 215 around the opening 214, and the sealing plate 215 extends around the circumference of the opening 214. The sealing plate 215 can be supported against the door body 220 to improve the sealing performance between the door body 220 and the door frame 210. The outer wall of the door frame 210 is arranged relative to the receiving space 140.

[0059] See also Figure 2 , Figures 7 to 12 In this embodiment, the door body 220 is rotatably connected to the door frame 210 so as to open and close the opening 214 on the door frame 210, thereby facilitating the installation, disassembly and maintenance of the energy storage structure 300. The door body 220 includes a door panel 221 and a door lock structure 222. The door panel 221 is arranged corresponding to the door frame 210, and the door panel 221 is rotatably connected to the vertical beam 213. The door lock structure 222 penetrates the door panel 221, and the door lock structure 222 can limit the door panel 221 on the door frame 210 to ensure that the door body 220 is stably in a closed state.

[0060] The door panel 221 is rotatably connected to the outer side wall of the vertical beam 213, and the door panel 221 can cover and block the opening 214 to protect the electrical components in the receiving space 140. When the door panel 221 is covered on the door frame 210, the outer side wall of the door panel 221 is located on the inner side of the outer side wall of the upper side beam 110, and the outer side wall of the door panel 221 is located on the inner side of the outer side wall of the lower side beam 120, so that the size parameters of the frame 100 structure can be increased to increase the effective volume in the container.

[0061] In some embodiments, when the door panel 221 covers the door frame 210 and the door assembly 200 is in a closed state, the outer side wall of the door panel 221 is located in the same plane as the outer side wall of the upper side beam 110. The outer side wall of the door panel 221 is located in the same plane as the outer side wall of the lower side beam 120, thereby increasing the size parameters of the frame 100 structure to increase the effective volume in the container.

[0062] See also Figure 2 , Figures 7 to 12 The door lock structure 222 includes a locking member 2221 and a locking tongue 2222. The locking member 2221 penetrates the door panel 221. The locking tongue 2222 is arranged on the inner side of the door panel 221. The locking tongue 2222 is in transmission connection with the locking member 2221. The locking tongue 2222 can rotate around the locking member 2221 to abut against the inner side wall of the door frame 210, so as to lock the door panel 221 on the door frame 210, and the door body 220 is in a closed state.

[0063] In the related art, the door body 220 of the container is generally locked by a bolt structure. The bolt structure is arranged on the outer wall of the door body 220 to facilitate the staff to open and lock the door body 220. However, the locking member 2221 of the present technical solution passes through the door panel 221, and the lock tongue 2222 is located on the inner side of the door panel 221, which is a hidden door lock structure 222. By reducing the space occupied by the door lock structure 222, the size parameters of the mobile energy storage container in the front and rear directions and the left and right directions are increased, thereby effectively increasing the effective volume in the container and improving the space utilization efficiency of the mobile energy storage container.

[0064] See also Figures 7 to 12 In this embodiment, the door lock structure 222 further includes a moving member 2223 and a limiting roller 2224. The moving member 2223 extends in the up-down direction, and is located at the inner side of the door panel 221. One end of the moving member 2223 is transmission-connected to the locking member 2221, and the locking member 2221 can drive the moving member 2223 to move in the up-down direction, and the other end of the moving member 2223 is connected to the limiting roller 2224. The limiting roller 2224 can abut against the rear side wall of the door frame 210 to limit the door body 220 on the door frame 210.

[0065] When the door panel 221 covers the outer wall of the door frame 210, the staff rotates the locking member 2221, and the locking member 2221 drives the locking tongue 2222 to rotate, so that the locking tongue 2222 abuts against the rear side wall of the door frame 210, thereby limiting the door panel 221 on the door frame 210. At the same time, the locking member 2221 can also drive the moving member 2223 to move upward, so that the limiting roller 2224 can roll upward on the rear side wall of the door frame 210 and abut against the rear side wall of the door frame 210, thereby limiting the door panel 221 on the door frame 210, improving the locking strength of the door assembly 200, and ensuring the structural strength of the mobile energy storage container.

[0066] In some embodiments, the door lock structure 222 is disposed near the lower end of the door body 220 so that the lock tongue 2222 can abut against the rear side wall of the vertical beam 213, and the limiting roller 2224 can abut against the rear side wall of the upper door beam 211. In other embodiments, the moving member 2223 can extend downward so that the limiting roller 2224 can abut against the rear side wall of the lower door beam 212.

[0067] When the mobile energy storage container is set on the vehicle body, the door lock structure 222 near the lower end of the door body 220 is convenient for the staff to open and lock the door body 220 on the road, thereby effectively improving the use efficiency of the mobile energy storage container and reducing labor costs.

[0068] In some embodiments, the door lock structure 222 further includes a support block 2225, which is disposed on the rear side wall of the door panel 221. The support block 2225 is used to support the moving member 2223 so that the moving member 2223 can stably move in the up and down directions, thereby ensuring the reliability and safety of the door lock structure 222.

[0070] See also Figures 7 to 13 In this embodiment, the door body 220 further includes a sealing ring 223 disposed on the inner side of the door plate 221. The sealing ring 223 is disposed relative to the sealing plate 215 and extends in a rectangular shape. When the door body 220 covers the door frame 210, the sealing ring 223 seals against the sealing plate 215 to improve the sealing performance between the door plate 221 and the door frame 210.

[0071] See also Figures 7 to 13 In this embodiment, the door body 220 further includes a reinforcement member 224, which is located on the inner side wall of the door panel 221 and extends in a rectangular shape. The reinforcement member 224 is located within the enclosed range of the sealing ring 223.
