[0025] The following is a more detailed description of a door structure and energy storage box according to the present invention, with reference to the accompanying drawings, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0026] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0027] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a door structure, including a door frame 1 and a door leaf 2.

[0028] Specifically, the door leaf 2 is rotatably connected to the door frame 1; a U-shaped structure 3 is provided along the edge of the door frame 1; a waterproof strip 4 is provided at the bent end of the U-shaped structure 3, which abuts against the door leaf 2 when the door leaf 2 is closed; a protrusion 6 extends outward from one side of the door leaf 2; the waterproof strip 4 abuts against the protrusion 6; a fireproof strip 5 is provided at the gap between the door frame 1 and the door leaf 2, which expands to fill the gap when exposed to fire. For example, the fireproof strip 5 is provided on the door leaf 2 and located between the U-shaped structure 3 and the door leaf 2. This embodiment, through the provision of the waterproof strip 4 and the fireproof strip 5, can simultaneously provide fireproof, waterproof, and dustproof functions.

[0029] Preferably, the fireproof strip 5 is provided at the gap between the protrusion 6 and the door frame 1. Specifically, the protrusion 6 can be a portion of the door leaf 2 protruding outward, forming a stepped structure. The waterproof strip 4 directly abuts against the surface of the protrusion 6, forming the first waterproof barrier. The fireproof strip 5 is provided at the gap between the protrusion 6 and the door frame 1, forming the first fireproof barrier. In this embodiment, the provision of the protrusion 6 increases the contact area between the door leaf 2 and the waterproof strip 4, improves the sealing effect, and provides a suitable installation position for the fireproof strip 5, thus optimizing and integrating fireproof and waterproof functions, achieving double or even multiple fireproof isolation effects. That is to say, the door structure in this embodiment is provided with double or even multiple fireproof strips 5 and a waterproof strip 4, thereby meeting both the 120-minute fire resistance requirement and the IP (International Protection, abbreviated as "IP") 55 waterproof and dustproof requirements.

[0030] In this embodiment, the door frame 1 is made of metal, such as steel or aluminum alloy, which are high-strength materials, to improve the overall rigidity and deformation resistance of the door structure. The door leaf 2 is connected to the door frame 1 via a rotating structure 10, for example, via a hinge, allowing the door leaf 2 to rotate and open around the hinge axis.

[0031] In one specific example, the U-shaped structure 3 is integrally formed with or welded to the door frame 1, and the waterproof strip 4 and fireproof strip 5 are fixed in their respective positions by embedded slots or adhesive bonding. In this embodiment, when the door leaf 2 is closed, the waterproof strip 4 is compressed by the door leaf 2 to form a sealed waterproof barrier; when a fire occurs, the fireproof strip 5 expands due to heat, filling all gaps between the door leaf 2 and the U-shaped structure 3, effectively preventing the spread of fire.

[0032] In one embodiment, the U-shaped structure 3 extends from one side of the door frame 1 toward the door leaf 2, and the U-shaped structure 3 is an inverted U-shaped structure with its opening facing the door frame 1. Specifically, the opening of the inverted U-shaped structure faces the inside of the door frame 1, forming an inwardly recessed space, so that when the door leaf 2 is closed, it can overlap with the U-shaped structure 3, thereby enhancing the waterproof sealing effect.

[0033] In a specific example, the U-shaped structure 3 includes a first segment 31, a second segment 32, and a third segment 33 (i.e., the bent end) connected in sequence; the end of the first segment 31 away from the second segment 32 is connected to the door frame 1; the second segment 32 is arranged parallel to the door frame 1; the third segment 33 is parallel to the first segment 31 and perpendicular to the second segment 32; the waterproof strip 4 is disposed on the outer wall of the third segment 33.

[0034] The first segment 31 extends perpendicularly to the door frame 1, the second segment 32 extends parallel to the door frame 1, and the third segment 33 extends perpendicularly to the door frame 1, forming a complete inverted U-shape. A waterproof strip 4 is installed on the outer wall of the third segment 33. When the door 2 is closed, the waterproof strip 4 directly contacts the door 2, forming a tightly fitting seal. This three-segment structure enhances the overall strength of the U-shaped structure 3, improves the deformation resistance of the door frame 1, and provides a stable installation base for the waterproof strip 4. Furthermore, it is worth mentioning that the waterproof strip 4 installed between the door frame 1 and the U-shaped structure 3 forms a sealed structure with the door 2, achieving an IP55 waterproof rating.

[0035] In this embodiment, the groove width of the U-shaped structure 3 is smaller than the thickness of the door leaf 2; the length of the third segment 33 is smaller than the length of the first segment 31. This arrangement is mainly used to control the size of the gap between the door leaf 2 and the U-shaped structure 3. By precisely controlling the groove width of the U-shaped structure 3 and the length of the third segment 33, precise control of the gap between the door leaf 2 and the door frame 1 is achieved, improving the overall sealing performance and optimizing the smoothness of opening and closing the door leaf 2. The groove width refers to the straight-line distance between the second segment 32 and the end of the first segment 31 furthest from the second segment 32.

[0036] Preferably, the waterproof strip 4 is an OC rubber strip. Specifically, the OC rubber strip is a rubber material with excellent elasticity and sealing performance. Its cross-sectional shape is a combination of O-shape and C-shape. This special shape allows the strip to deform well under pressure, providing a stronger sealing effect.

[0037] Preferably, the waterproof strip 4 is made of rubber, and the compression amount is not less than a set value. Those skilled in the art will know that the material of the waterproof strip 4 can be set according to actual needs, and other embodiments besides this one are also possible.

[0038] In this embodiment, the rubber strip can be solid or hollow. When the door 2 is fully closed, the waterproof strip 4 is compressed to at least a specified value to ensure an effective seal. The compression amount directly affects the waterproof performance; too little compression may result in insufficient sealing, while too much compression may increase the resistance to opening and closing the door. In this embodiment, the compression amount is not less than a set value, for example, not less than 2mm. That is, a suitable compression amount is set to provide a good sealing effect while also taking into account the ease of operation of opening and closing the door 2. As those skilled in the art will know, the compression amount can be adjusted according to the actual application environment and waterproof requirements, and other embodiments besides this one are also possible.

[0039] Preferably, the fireproof strip 5 is made of rubber and plastic, and its expansion ratio is not less than a preset ratio, for example, not less than 3 times. Those skilled in the art will know that the expansion ratio can be set according to actual fire protection requirements, and other embodiments besides this one are also included, allowing it to expand to several times its original volume at high temperatures, filling larger gaps. This embodiment can enhance the sealing ability of the fireproof strip 5 under fire conditions and also improve the overall fire resistance performance.

[0040] Preferably, both the door frame 1 and the sidewalls of the U-shaped structure 3 are provided with fire-retardant coating 7. Specifically, the fire-retardant coating 7 can be an inorganic fire-retardant coating 7 or an intumescent fire-retardant coating 7, and the coating thickness can be set according to actual needs. The fire-retardant coating 7 can be applied to all exposed surfaces of the door frame 1 and the U-shaped structure 3, forming a heat insulation layer in the event of a fire and reducing the heat conduction rate. The application of the fire-retardant coating 7 can enhance the overall fire resistance of the door structure, extend its integrity maintenance time under fire conditions, and form a synergistic fire protection system with the fire-resistant strip 5, further improving the fire resistance rating of the door structure.

[0041] In addition, in this embodiment, both the door leaf 2 and the door frame 1 are internally filled with fire-resistant materials. For example, the interior of the door leaf 2 can be filled with rock wool and nano-boards, which can improve the fire resistance and heat insulation performance of the door leaf 2. In one embodiment, the interior of the door frame 1 can also be filled with rock wool, which improves the fire resistance performance of the door frame 1 under fire conditions. As those skilled in the art will know, the selection of fire-resistant materials can be set according to actual needs, and other embodiments besides this one are also included.

[0042] Furthermore, this embodiment also proposes an energy storage box, including a box body and a door structure as described above, wherein the door structure is installed on the box body (not shown in the figure for simplicity). Specifically, the box body can be a container-type structure, with energy storage equipment, a heat dissipation system, and a control system installed inside. The door structure is installed at the opening of the box body by welding or bolting to form a complete energy storage box.

[0043] In a specific example, continue to refer to Figure 3 As shown, the door structure (or door leaf 2) is also provided with a corresponding door handle 8 and door closer 9.

[0044] In this embodiment, when the door leaf 2 is closed, the protrusion 6 presses against the waterproof strip 4 on the outer wall of the third section 33 of the U-shaped structure 3, forming a highly efficient waterproof sealing interface to prevent external moisture and dust from intruding. In the event of a fire, the fireproof strips 5 installed at the gaps between the door leaf 2 and the U-shaped structure 3, and between the protrusion 6 and the door frame 1, undergo a chemical reaction, expanding to several times their original volume and completely filling all gaps. At the same time, the fireproof coating 7 on the side walls of the door frame 1 and the U-shaped structure 3 forms a heat insulation layer, jointly constructing a fire barrier to prevent the spread of fire and heat conduction.

[0045] In summary, the door structure and energy storage box proposed in this utility model have the following advantages:

[0046] The device utilizes a door frame and door leaf design; the door leaf is rotatably connected to the door frame; a U-shaped structure is installed along the edge of the door frame; a waterproof strip is installed at the bent end of the U-shaped structure, which abuts against the door leaf when it is closed; one side of the door leaf extends outward to form a protrusion; the waterproof strip abuts against the protrusion; a fireproof strip is installed in the gap between the door frame and the door leaf, which expands and fills the gap when exposed to fire. This device simultaneously provides fireproof, waterproof, and dustproof functions, with an ingenious design, reasonable structure, and the door structure does not require excessive cabinet space.

[0047] Furthermore, by designing the U-shaped structure as a three-section inverted U-shape, and ensuring the groove width is less than the door leaf thickness, combined with the coordinated design of the door leaf protrusion and waterproof strip, the waterproof sealing effect is further enhanced. Rubber and plastic strips with an expansion ratio not less than a preset multiple are used as fireproof strips, and fire-retardant coatings are applied to the door frame and the side walls of the U-shaped structure, forming multiple fire protection barriers. This significantly improves the overall protective performance of the door structure and ensures the safe operation of the equipment inside the energy storage box. The door structure is equipped with double or even multiple fireproof strips and waterproof strips, thus meeting both the 120-minute fire resistance requirement and the IP55 waterproof and dustproof requirement.

[0048] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
