Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to a door opening and closing booster structure and an energy storage cabinet. Background Technology

[0002] With the widespread application of energy storage technology, the frequency of use of energy storage cabinets is constantly increasing. During daily opening and closing, due to factors such as the weight of the cabinet door itself, installation precision, and the usage environment, corner sagging often occurs, meaning that one side or corner of the cabinet door droops, preventing the cabinet door from closing completely.

[0003] Corner chipping can prevent a tight seal between the cabinet door and the cabinet body, creating noticeable gaps. This allows external dust to easily enter the cabinet, and dust accumulation can cause short circuits in precision components, poor heat dissipation, and other problems, severely impacting performance and lifespan. Simultaneously, moisture can also seep in, creating a damp environment inside the cabinet, accelerating corrosion of metal parts and further damaging components. Furthermore, decreased sealing performance increases the risk of foreign object intrusion, especially in industrial environments or outdoor locations. Debris, small particles, and even insects can become stuck between the moving parts of the cabinet door and body, hindering normal opening and closing, and potentially causing physical damage to internal wiring and connectors, leading to system malfunctions. Long-term corner chipping also causes severe mechanical wear on the cabinet door and body. Due to uneven stress caused by the sagging door, the parts in contact with the cabinet body experience additional friction and pressure during opening and closing. In addition, poor sealing due to corner chipping reduces the thermal insulation performance of the energy storage cabinet, requiring more energy to maintain the internal temperature, resulting in energy waste and increased operating costs. Utility Model Content

[0004] The purpose of this application is to provide a door opening and closing boosting structure. By setting a first boosting component and a second boosting component between the cabinet door and the cabinet body, and utilizing a boosting ramp to raise the cabinet door to a set height when closed, this effectively solves the problem of reduced sealing caused by the corner of the cabinet door, ensuring that the cabinet door can fit tightly against the cabinet body, preventing dust and moisture from entering the cabinet, thereby improving the protective performance and service life of the energy storage cabinet. Another purpose of this application is to provide an energy storage cabinet.

[0005] To achieve the above objectives, this application provides a door opening and closing boosting structure for an energy storage cabinet, including a first boosting component and a second boosting component. The first boosting component is disposed in either the cabinet door or the cabinet body of the energy storage cabinet, and the second boosting component is disposed in the other of the cabinet door and the cabinet body.

[0006] The first pusher component is provided with a pusher ramp. When the cabinet door rotates and closes relative to the cabinet body, the second pusher component contacts the pusher ramp, causing the cabinet door to be raised to a set height under the action of the pusher ramp, thereby achieving the sealing of the cabinet door to the cabinet body.

[0007] In some embodiments, the first booster component is fixed to the cabinet door of the energy storage cabinet, and the second booster component is fixed to the cabinet body of the energy storage cabinet. The first booster component is made to climb on the second booster component by using the booster ramp, so that the cabinet door is raised.

[0008] In some embodiments, the door opening and closing assist structure further includes a support device, which is disposed on the cabinet of the energy storage cabinet and located on one side of the door hinge of the energy storage cabinet door. The support device supports the cabinet door upward from the lower side of the cabinet door.

[0009] In some embodiments, the second booster assembly includes a roller for rolling on the booster ramp.

[0010] In some embodiments, there are multiple contact points between the first booster component and the second booster component in the width direction of the cabinet door of the energy storage cabinet.

[0011] In some embodiments, the slope of the booster ramp ranges from 1° to 30°.

[0012] In some embodiments, there are multiple second booster components, which are distributed along the width direction of the cabinet door and cabinet body of the energy storage cabinet, and the first booster component extends along the width direction of the cabinet door and cabinet body of the energy storage cabinet.

[0013] In some embodiments, in the extending direction of the first booster component, the booster ramp includes multiple ramp units, each ramp unit corresponding to a plurality of second booster components, and the slope of the ramp unit gradually increases in the direction away from the door hinge of the energy storage cabinet.

[0014] In some embodiments, the first booster component includes a first sheet metal part and a second sheet metal part, the first sheet metal part is bent on three sides, the second sheet metal part is fixed inside the bent part of the first sheet metal part, and the second sheet metal part is provided with the booster ramp.

[0015] This application also provides an energy storage cabinet, including the aforementioned door opening and closing booster structure.

[0016] Compared with the above-mentioned background technology, the door opening and closing boosting structure of the energy storage cabinet provided in this application mainly includes a first boosting component and a second boosting component. The first boosting component is located in either the cabinet door or the cabinet body of the energy storage cabinet, and the second boosting component is located in the other of the cabinet door and the cabinet body. The first boosting component is provided with a boosting ramp. When the cabinet door rotates and closes relative to the cabinet body, the second boosting component contacts the boosting ramp, causing the cabinet door to be raised to a set height under the action of the boosting ramp, thereby achieving the closing of the cabinet door to the cabinet body.

[0017] In the background technology, corner sagging of energy storage cabinet doors is a common problem. Due to factors such as the weight of the cabinet door itself and installation precision, one side or corner of the door is prone to sagging, preventing the door from closing completely and creating a noticeable gap between it and the cabinet body. These gaps allow external dust and moisture to easily enter the cabinet. Dust accumulation can lead to short circuits and poor heat dissipation in precision components, severely affecting component performance and lifespan. Simultaneously, moisture creates a damp environment inside the cabinet, accelerating corrosion of metal parts and further damaging components. Furthermore, decreased sealing performance increases the risk of foreign object intrusion, potentially obstructing normal door opening and closing, and even causing system malfunctions.

[0018] To address these issues, this application provides a door-opening and closing boosting structure for an energy storage cabinet. This structure mainly includes a first boosting component and a second boosting component. The first boosting component is located on either the cabinet door or the cabinet body, while the second boosting component is located on the other. The first boosting component has a boosting ramp; when the cabinet door rotates to close relative to the cabinet body, the second boosting component contacts the boosting ramp. Under the action of the boosting ramp, the cabinet door can be raised to a set height, thereby achieving a tight seal between the cabinet door and the cabinet body. This design effectively overcomes the problem of reduced sealing caused by the corner of the cabinet door, ensuring that the cabinet door fits tightly against the cabinet body when closed, preventing dust and moisture from entering the cabinet.

[0019] This door-opening assist structure provides better protection for the components inside the energy storage cabinet. Dust and moisture cannot easily enter the cabinet, thus avoiding performance degradation and shortened lifespan caused by dust accumulation and moisture corrosion. Furthermore, this structure reduces the risk of foreign object intrusion, ensures the normal opening and closing of the cabinet door, and improves the protective performance and service life of the energy storage cabinet.

[0020] Based on the above structural and process descriptions, it can be seen that the door opening and closing booster structure has at least the following beneficial effects: By setting a first booster component and a second booster component between the cabinet door and the cabinet body, and using the booster ramp to raise the cabinet door to a set height when closed, the door opening and closing booster structure effectively solves the problem of reduced sealing caused by the corner of the cabinet door, ensuring that the cabinet door can fit tightly against the cabinet body, preventing dust and moisture from entering the cabinet, thereby improving the protective performance and service life of the energy storage cabinet.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] Please refer to Figures 1 to 3 ,in, Figure 1 This is a schematic diagram of the door opening and closing assist structure provided in an embodiment of this application. Figure 2 This is a schematic diagram of the door opening and closing booster structure provided in an embodiment of this application. Figure 3 This is a schematic diagram of the door opening / closing booster structure and energy storage cabinet provided in the embodiments of this application.

[0040] In a first specific embodiment, the door opening and closing boosting structure 100 of the energy storage cabinet provided in this application mainly includes a first booster 1 and a second booster 2. The first booster 1 is provided on either the cabinet door 4 or the cabinet body 5 of the energy storage cabinet 200, and the second booster 2 is provided on the other of the cabinet door 4 and the cabinet body 5. The first booster 1 is provided with a boosting ramp 101. When the cabinet door 4 rotates and closes relative to the cabinet body 5, the second booster 2 contacts the boosting ramp 101, so that the cabinet door 4 is raised to a set height under the action of the boosting ramp 101, thereby achieving the closing of the cabinet door 4 to the cabinet body 5.

[0041] In the background technology, corner sagging of the energy storage cabinet door 4 is a common problem. Due to factors such as the weight of the door 4 itself and installation precision, one side or corner of the door 4 is prone to sagging, causing the door 4 to fail to close completely, resulting in a noticeable gap between the door 4 and the cabinet body 5. These gaps allow external dust and moisture to easily enter the cabinet. Dust accumulation can lead to short circuits and poor heat dissipation in precision components, severely affecting component performance and lifespan. Simultaneously, moisture creates a damp environment inside the cabinet, accelerating the corrosion of metal parts and further damaging the components. Furthermore, decreased sealing performance increases the risk of foreign object intrusion, potentially obstructing the normal opening and closing of the door 4, or even causing system malfunctions.

[0042] To address these issues, this application provides a door-opening and closing assist structure 100 for an energy storage cabinet 200. This structure mainly includes a first assist component 1 and a second assist component 2. The first assist component 1 is located on either the cabinet door 4 or the cabinet body 5 of the energy storage cabinet 200, while the second assist component 2 is located on the other of the cabinet door 4 and the cabinet body 5. The first assist component 1 has an assisting ramp 101. When the cabinet door 4 rotates to close relative to the cabinet body 5, the second assist component 2 contacts the assisting ramp 101. Under the action of the assisting ramp 101, the cabinet door 4 can be raised to a set height, thereby achieving a tight seal between the cabinet door 4 and the cabinet body 5. This design effectively overcomes the problem of reduced sealing caused by the corner of the cabinet door 4, ensuring that the cabinet door 4 can tightly fit against the cabinet body 5 when closed, preventing dust and moisture from entering the cabinet.

[0043] Through this door-opening and closing booster structure 100, the components inside the energy storage cabinet 200 are better protected. Dust and moisture cannot easily enter the cabinet, thus avoiding performance degradation and shortened lifespan caused by dust accumulation and moisture corrosion. In addition, this structure also reduces the risk of foreign object intrusion, ensures the normal opening and closing of the cabinet door 4, and improves the protective performance and service life of the energy storage cabinet 200.

[0044] Based on the above structural and process descriptions, it can be seen that the door opening and closing assist structure 100 has at least the following beneficial effects: By setting a first assist component 1 and a second assist component 2 between the cabinet door 4 and the cabinet body 5, and using the assisting inclined surface 101 to raise the cabinet door 4 to a set height when closed, the door opening and closing assist structure 100 effectively solves the problem of reduced sealing caused by the corner of the cabinet door 4, ensuring that the cabinet door 4 can fit tightly against the cabinet body 5, preventing dust and moisture from entering the cabinet, thereby improving the protective performance and service life of the energy storage cabinet 200.

[0045] It should be noted that, as Figure 1 and Figure 2 As shown, in the energy storage cabinet door opening and closing booster structure 100 of this application, the fixed positions of the first booster 1 and the second booster 2 have two different configurations.

[0046] The first configuration involves fixing the first pusher 1 to the cabinet door 4 of the energy storage cabinet 200, while the second pusher 2 is fixed to the cabinet body 5. In this configuration, when the cabinet door 4 rotates to close relative to the cabinet body 5, the first pusher 1 on the cabinet door 4 moves with the rotation of the cabinet door. At this time, the pusher ramp 101 on the first pusher 1 contacts the second pusher 2 on the cabinet body 5. Under the action of the pusher ramp 101, the cabinet door 4 is raised to a set height, thereby achieving a tight seal on the cabinet body 5. This design allows the cabinet door 4 to overcome the adverse effects of corner damage when closed, ensuring that there are no gaps between the cabinet door 4 and the cabinet body 5, effectively preventing dust and moisture from entering the cabinet.

[0047] The second configuration involves fixing the first pusher 1 to the cabinet body 5 of the energy storage cabinet 200, while the second pusher 2 is fixed to the cabinet door 4. In this case, when the cabinet door 4 rotates and closes relative to the cabinet body 5, the first pusher 1 on the cabinet body 5 remains stationary, while the second pusher 2 on the cabinet door 4 moves with the rotation of the cabinet door. When the second pusher 2 contacts the pusher ramp 101 on the first pusher 1, the cabinet door 4 is also lifted to a set height under the action of the pusher ramp 101, achieving a tight seal on the cabinet body 5.

[0048] Although the first booster 1 and the second booster 2 are fixed in different positions, they both ultimately lift the cabinet door 4 through the action of the booster ramp 101, ensuring that the cabinet door 4 can fit tightly against the cabinet body 5, preventing dust and moisture from entering the cabinet, thereby improving the sealing and protection performance of the energy storage cabinet 200.

[0049] In some embodiments, such as Figure 3 As shown, the first booster 1 is fixed to the cabinet door 4 of the energy storage cabinet 200, and the second booster 2 is fixed to the cabinet body 5 of the energy storage cabinet 200. The first booster 1 is lifted on the second booster 2 by using the booster ramp 101, thereby raising the cabinet door 4.

[0050] In this embodiment, the first pusher 1 is fixed to the cabinet door 4 of the energy storage cabinet 200, while the second pusher 2 is fixed to the cabinet body 5. When the cabinet door 4 rotates and closes relative to the cabinet body 5, the first pusher 1 moves with the rotation of the cabinet door. Since the position of the second pusher 2 is fixed, it provides a stable guide for the first pusher 1. When the pusher ramp 101 on the first pusher 1 contacts the second pusher 2, the second pusher 2 applies an upward force to the first pusher 1. This force causes the first pusher 1 to climb along the pusher ramp 101 on the second pusher 2, thereby lifting the entire cabinet door 4 to a set height. Through this design, the cabinet door 4 can overcome the corner-dropping phenomenon when closed, achieving a tight fit with the cabinet body 5 and ensuring the airtightness of the energy storage cabinet 200.

[0051] It should be noted that the specific structural form of the second pusher 2 and its function on the first pusher 1 are not limited. For example, the second pusher 2 can be a block structure, in which case its interaction with the first pusher 1 is mainly achieved through sliding friction. When the cabinet door 4 is closed, the pushing ramp 101 on the first pusher 1 contacts the block surface of the second pusher 2, and the first pusher 1 climbs along the second pusher 2 through sliding friction, thereby lifting the cabinet door 4. In addition, the second pusher 2 can also be designed with a rotating structure. Whether it is sliding friction or rolling friction, both of these different structural forms and functions can effectively make the first pusher 1 climb on the second pusher 2, thereby lifting the cabinet door 4 to a set height and ensuring a tight seal between the cabinet door 4 and the cabinet body 5, and both should be within the scope of this embodiment.

[0052] Please continue to refer to this. Figure 3 In some embodiments, the door opening and closing assist structure 100 further includes a support device 3, which is disposed on the cabinet body 5 of the energy storage cabinet 200. The support device 3 is located on the door hinge side of the cabinet door 4 of the energy storage cabinet 200, and supports the cabinet door 4 upward from the lower side of the cabinet door 4.

[0053] In this embodiment, the main function of the support device 3 is to provide upward support on the underside of the cabinet door 4, thereby bearing the weight of the cabinet door 4. In this way, the support device 3 can effectively reduce the stress on the hinge side of the cabinet door 4. Because the weight of the cabinet door 4 is additionally supported, the pressure and stress on the hinge are reduced, thereby reducing the corner sagging of the cabinet door 4 due to long-term use or its own weight. This design not only improves the stability and durability of the cabinet door 4, but also ensures that the cabinet door 4 can operate more smoothly during opening and closing, further enhancing the overall performance and service life of the energy storage cabinet 200.

[0054] It should be noted that the specific structural form and function of the supporting device 3 are not limited. For example, the supporting device 3 can adopt a simple block structure, supporting the cabinet door by generating sliding friction with the contact surface on the lower side of the cabinet door 4, providing a stable supporting force for the cabinet door 4, thereby reducing the stress on the hinge side. In addition, the supporting device 3 can also be designed to include rolling elements such as rollers or bearings. In this way, during the opening and closing of the cabinet door 4, the friction between the supporting device 3 and the cabinet door 4 is transformed into rolling friction, which can more smoothly support the weight of the cabinet door 4, while reducing frictional resistance and wear, and extending the service life of the supporting device 3 and the cabinet door 4. Whether sliding friction or rolling friction is used, or any other structural form that can achieve the supporting function, as long as it can effectively reduce the axial stress of the cabinet door 4 and reduce corner chipping, it should be within the scope of this embodiment.

[0055] Please refer to Figure 4 , Figure 4 A schematic diagram of the second booster component provided in an embodiment of this application.

[0056] In some embodiments, the second booster 2 includes a roller 21 for rolling on the booster ramp 101.

[0057] In this embodiment, the second pusher 2 is specifically designed to include a roller 21. The main function of the roller 21 is to roll on the pusher ramp 101 of the first pusher 1. When the cabinet door 4 rotates and closes relative to the cabinet body 5, the pusher ramp 101 on the first pusher 1 contacts the roller 21 of the second pusher 2. The roller 21 rolls along the pusher ramp 101, thereby lifting the cabinet door 4 to a set height. This design uses rolling friction instead of traditional sliding friction, which can significantly reduce frictional resistance and wear, making the lifting process of the cabinet door 4 smoother and more efficient. At the same time, the rolling motion of the roller 21 also helps to improve the stability and durability of the door opening and closing pusher structure 100, ensuring that the cabinet door 4 can stably and tightly seal the cabinet body 5 for a long time.

[0058] In some cases, the second booster assembly 2 includes a roller 21, a bracket 22, and a fixed shaft 23. The bracket 22 serves as a support structure, and the fixed shaft 23 is positioned between the two side lugs of the bracket 22. The roller 21 is fitted onto the fixed shaft 23. The bracket 22 has mounting holes and is fixed to the energy storage cabinet 200 using fasteners. Figure 3 As shown, the bracket 22 of the second booster component 2 is fixed on the cabinet 5, and correspondingly, the first booster component 1 is fixed on the cabinet door 4.

[0059] In some embodiments, there are multiple contact points between the first pusher 1 and the second pusher 2 in the width direction of the cabinet door 4 of the energy storage cabinet 200.

[0060] In this embodiment, this means that during the closing process of the cabinet door 4, different positions on the first pusher 1 will interact sequentially or simultaneously with multiple contact points on the second pusher 2. This design allows the cabinet door 4 to be subjected to more even force during the lifting process, avoiding excessive local stress caused by force concentration, thereby reducing the risk of deformation or damage to the cabinet door 4. At the same time, the setting of multiple contact points also helps to improve the adaptability and flexibility of the pusher structure, enabling it to better cope with cabinet doors of different sizes and weights, ensuring that the cabinet door 4 can be lifted smoothly and accurately to the set height, achieving a tight seal on the cabinet 5. In addition, this multi-point contact design can also increase the redundancy of the pusher structure. Even if one contact point fails due to wear or other reasons, the other contact points can still continue to function, ensuring the reliability and durability of the door opening and closing pusher structure 100.

[0061] In some embodiments, the slope of the booster ramp 101 ranges from 1° to 30°.

[0062] In this embodiment, this design allows for flexible adjustment of the slope of the booster ramp 101 based on factors such as the specific operating environment of the energy storage cabinet 200 and the weight of the cabinet door 4, to achieve the best boosting effect. When the slope is small, such as close to 0°, the booster ramp 101 is relatively gentle, and the lifting force required for the cabinet door 4 to close is small. This is suitable for situations where the cabinet door 4 is relatively light or the sealing requirements are not particularly high. As the slope gradually increases, the booster ramp 101 becomes steeper, and the cabinet door 4 can obtain a greater lifting force when closing, thereby better overcoming the corner drop phenomenon and ensuring a tight fit between the cabinet door 4 and the cabinet body 5. This is suitable for situations where the cabinet door 4 is heavier or the sealing performance requirements are high. However, the slope cannot be too large, such as exceeding 30°; otherwise, it will be detrimental to the continuous lifting of the cabinet door 4, making the closing action difficult, and may cause the cabinet door 4 to over-lift or other unstable phenomena during the closing process. Therefore, limiting the slope of the booster ramp 101 to the range of 1° to 30° can meet different usage requirements and ensure the stability and reliability of the door opening and closing booster structure 100.

[0063] Preferably, the slope of the booster ramp 101 is 15°.

[0064] In some embodiments, there are multiple second boosters 2, which are distributed along the width direction of the cabinet door 4 and cabinet body 5 of the energy storage cabinet 200, and the first booster 1 extends along the width direction of the cabinet door 4 and cabinet body 5 of the energy storage cabinet 200.

[0065] In this embodiment, this design first creates multiple contact points, thereby dispersing the force on the cabinet door 4 during closing. This avoids deformation or damage to the cabinet door 4 due to excessive local force, improving the stability and durability of the cabinet door 4.

[0066] Furthermore, this design fully utilizes the rotational characteristics of the cabinet door 4. When the cabinet door 4 rotates to close, the first pusher 1 sequentially contacts the rollers 21 on each of the second pushers 2. Each time they contact, the rollers 21 roll on the pusher ramp 101, generating an upward lifting force on the cabinet door 4. As the cabinet door 4 continues to rotate, the contact point between the first pusher 1 and the second pusher 2 gradually moves towards the closing direction of the cabinet door 4, and the rollers 21 gradually correct any potential corner slippage that might occur with the cabinet door 4. This gradual correction process allows the cabinet door 4 to be lifted more smoothly and accurately to the set height, ultimately achieving a tight seal on the cabinet body 5.

[0067] In some cases, the second booster assembly 2 is fixed to the cabinet 5, and multiple second booster components 2, i.e., rollers 21, are distributed along the width direction of the cabinet 5 of the energy storage cabinet 200.

[0068] Preferably, multiple second booster elements 2 are evenly distributed.

[0069] Furthermore, the spacing between the multiple second booster components 2, i.e., the rollers 21, is 600mm.

[0070] Furthermore, the number of the second booster 2, namely the roller 21, is three, and the distance between adjacent rollers 21 is equal at 600mm.

[0071] Furthermore, roller 21 is a silent roller, which reduces noise when opening and closing the door and provides a smooth pushing force.

[0072] In some embodiments, in the extending direction of the first booster 1, the booster ramp 101 includes multiple ramp units, each ramp unit corresponding to a plurality of second boosters 2, and the slope of the ramp unit gradually increases in the direction away from the door hinge of the cabinet door 4 of the energy storage cabinet 200.

[0073] In this embodiment, this design cleverly utilizes the closing process of the cabinet door 4, so that when the cabinet door 4 closes, the slope provided by the first contacting second push member 2, i.e., the roller 21, is relatively small. As the cabinet door 4 continues to close, the slope provided by the subsequent contacting second push member 2, i.e., the roller 21, gradually increases. This design allows the cabinet door 4 to undergo a smooth lifting process during the closing process.

[0074] Specifically, when cabinet door 4 begins to close, the first inclined unit of the first pusher 1 first contacts the first second pusher 2 closest to the door hinge of cabinet door 4. At this time, due to the small slope of this inclined unit, the lifting force of the roller 21 on cabinet door 4 is relatively gentle, which helps cabinet door 4 to begin to rise smoothly. As cabinet door 4 closes further, the other inclined units of the first pusher 1 gradually contact the subsequent second pushers 2, and the slope of the inclined units corresponding to these second pushers 2 gradually increases. This means that the lifting force of the roller 21 on cabinet door 4 is also gradually increasing, thereby more effectively overcoming the corner drop phenomenon of cabinet door 4 and ensuring that cabinet door 4 can be lifted to the set height.

[0075] Finally, when the cabinet door 4 is closed to a near-completely sealed position, the last inclined unit of the first booster 1 contacts the last second booster 2, at which point the slope of the inclined unit reaches its maximum. Through the last contacting second booster 2, i.e., the roller 21, the cabinet door 4 can complete the corner correction, achieving a tight fit with the cabinet body 5. The entire process is smooth and continuous, ensuring that the cabinet door 4 can smoothly overcome the corner problem when closing, improving the sealing and protection performance of the energy storage cabinet 200.

[0076] In some embodiments, the first booster assembly 1, the second booster assembly 2, and the support device 3 are manufactured from materials with good wear resistance in order to improve their service life and reduce maintenance costs.

[0077] Preferably, the second booster assembly 2, i.e., the roller 21, is made of high-strength TPU polyurethane to produce a silent roller. A wear-resistant layer can be provided on the surface of the first booster assembly 1 and the support device 3.

[0078] Please refer to Figure 5 , Figure 5 A schematic diagram of the first booster component provided in an embodiment of this application.

[0079] In some embodiments, the first booster 1 includes a first sheet metal part 11 and a second sheet metal part 12. The first sheet metal part 11 is bent on three sides, and the second sheet metal part 12 is fixed inside the bent part 11. The second sheet metal part 12 is provided with a booster ramp 101.

[0080] In this embodiment, the first sheet metal part 11 has a three-sided bending design. This structure provides additional reinforcement to the first pusher 1, significantly improving the overall structural strength. This reinforced structure allows the first pusher 1 to withstand greater forces, ensuring stable performance and a longer service life even when facing heavy cabinet doors or significant external pressure during the closing process of the cabinet door 4. The second sheet metal part 12 is fixed in the internal space formed by the bending of the first sheet metal part 11. The pusher ramp 101 is located on the lower side of the second sheet metal part 12. Correspondingly, the second sheet metal part 12, i.e., the roller 21, contacts the pusher ramp 101 on the lower side of the pusher ramp 101 to provide a lifting effect.

[0081] The second sheet metal part 12 and the first sheet metal part 11 together constitute the overall structure of the first booster 1. Both are sheet metal structural parts, which makes the first booster 1 simple in structure and low in cost. Because the processing technology for sheet metal parts is mature and cost-effective, the first booster 1 is easy to mass-produce and widely apply. This not only reduces equipment maintenance costs caused by cabinet door corner damage, but also reduces the failure rate, providing a strong guarantee for the long-term stable operation of the energy storage cabinet 200.

[0082] In some cases, the first sheet metal part 11 can be fixed to the cabinet door 4 by fasteners or welding. Fastener fixing facilitates installation and disassembly, and makes maintenance and replacement convenient, while welding provides a more robust connection and is suitable for applications requiring high stability and durability. Both fixing methods provide flexible options for the installation of the first booster 1 to adapt to different usage needs and production conditions.

[0083] Please refer to Figure 6 , Figure 6A schematic diagram of the support device provided in the embodiments of this application.

[0084] In some cases, in addition to the first push-up component 1 using sheet metal structural components, the supporting device 3 also uses sheet metal structural components. This design choice ensures consistency in materials and manufacturing processes throughout the entire door opening and closing push-up structure 100, further reducing production costs and manufacturing difficulty. Sheet metal structural components have good mechanical and processing properties, and can be efficiently processed into the required shapes and sizes through processes such as stamping and bending to meet the strength, rigidity, and stability requirements of the supporting device 3.

[0085] Please refer to Figure 7 , Figure 7 This is a schematic diagram of an energy storage cabinet provided in an embodiment of this application.

[0086] This application also provides an energy storage cabinet 200, including the aforementioned door opening and closing booster structure 100.

[0087] The energy storage cabinet 200 includes the aforementioned door opening and closing booster structure 100 and should have all the beneficial technical effects of the aforementioned door opening and closing booster structure 100.

[0088] Specifically, during use, the energy storage cabinet 200 effectively solves the problem of corner sagging caused by the weight of the cabinet door 4 and installation errors. Through the coordinated action of the first pusher 1 and the second pusher 2, and the auxiliary support of the support device 3, the cabinet door 4 can be smoothly lifted to the set height when closed, achieving a tight fit with the cabinet body 5. This not only improves the sealing performance of the energy storage cabinet 200, preventing the intrusion of dust, moisture, and other impurities, but also reduces the risk of foreign object intrusion due to poor sealing, ensuring the safe and stable operation of the components inside the cabinet.

[0089] Furthermore, the adoption of the door-opening assist structure 100 enhances the durability and reliability of the energy storage cabinet 200 during long-term use. Because the assist structure effectively distributes the force on the cabinet door 4, reducing stress concentration on the door hinge side, it lowers the likelihood of door deformation or damage, thus extending the service life of the energy storage cabinet 200. Simultaneously, the use of sheet metal structural components keeps the manufacturing cost of the energy storage cabinet 200 low, facilitating its widespread application and providing users with a cost-effective energy storage solution. In conclusion, the energy storage cabinet 200, with its unique door-opening assist structure 100, meets the comprehensive requirements of modern energy storage equipment for performance, reliability, and economy.

[0090] Please refer to Figure 8 , Figure 8 This is a cross-sectional view of the energy storage cabinet provided in an embodiment of this application.

[0091] Cabinet door 4 includes front door panel 41 and rear door panel 42, which are located on the front and rear sides of cabinet body 5.

[0092] In some cases, door opening and closing assist structures 100 are provided at two locations: between cabinet 5 and front door panel 41 and between cabinet 5 and rear door panel 42. The door opening and closing assist structure 100 referred to here includes a first assist component 1, a second assist component 2 and a support device 3.

[0093] Taking the front door panel 41 as an example, when the user closes the front door panel 41, the first pusher 1 and the second pusher 2 interact, and through the lifting action of the pusher ramp 101, the front door panel 41 can overcome the corner drop phenomenon, smoothly rise to the set height, and fit tightly against the cabinet body 5. At the same time, the support device 3 provides support on the lower side of the front door panel 41, reducing the stress on the door hinge side and ensuring the stable closing of the front door panel 41. Similarly, the door opening and closing pusher structure 100 set between the rear door panel 42 and the cabinet body 5 can also achieve smooth lifting and tight closing of the rear door panel 42.

[0094] By incorporating door-opening assist structures 100 between the front door panel 41 and the rear door panel 42 and the cabinet body 5, the sealing performance of the energy storage cabinet 200 is comprehensively improved. Whether the cabinet door is closed from the front or rear, it ensures no gaps between the door and the cabinet body, effectively preventing the intrusion of dust, moisture, and other impurities, while also reducing the risk of foreign objects entering the cabinet. This design allows the energy storage cabinet 200 to maintain excellent sealing and protective performance under various operating environments, providing a safer and more stable operating environment for the components inside the cabinet.

[0095] Please refer to Figure 9 and Figure 10 , Figure 9 This is a schematic diagram of unlocking the energy storage cabinet provided in an embodiment of this application. Figure 10 This is a schematic diagram of the locking mechanism of the energy storage cabinet provided in an embodiment of this application.

[0096] In some cases, the energy storage cabinet 200 also includes a mounting base 6, a door lock 7, and a locking rod 8. The mounting base 6 is located on the cabinet door 4, and the door lock 7 and locking rod 8 are installed as a set on the door panels (front door panel 41, rear door panel 42).

[0097] In this embodiment, the locking rod 8 is equipped with a latch, and the door lock 7 has the function of controlling the up and down movement of the locking rod 8. When the cabinet door 4 is fully closed, the center positions of the locking rod 8 and the fixing seat 6 need to be precisely on the same longitudinal axis. At this time, the user can operate by rotating the door lock 7. The rotation of the door lock 7 will drive the locking rod 8 to move up and down accordingly, thereby causing the latch on the locking rod 8 to move as well. When the latch successfully enters the fixing seat 6, the locking process of the cabinet door is completed, ensuring that the cabinet door 4 and the cabinet body 5 are tightly sealed, preventing the cabinet door from being opened accidentally, and enhancing the safety and reliability of the energy storage cabinet 200.

[0098] This lock structure design, working in conjunction with the door-opening push structure 100, not only improves the sealing performance of the cabinet door but also ensures its secure locking. During the closing process, the door-opening push structure 100, through the action of the first pusher 1, the second pusher 2, and the support device 3, smoothly raises the cabinet door 4 and tightly fits against the cabinet body 5; while the cooperation of the door lock 7 and the locking rod 8 provides reliable locking protection after the cabinet door is fully closed. The combination of these two features provides a safer, more stable, and more convenient experience for using the energy storage cabinet 200.
