Description

Technical Field

[0001] The present application relates to the technical field of rainproofing of cabinets and boxes, and in particular to a sealing strip, a cabinet and an energy storage device. Background Art

[0002] Existing outdoor cabinets, such as energy storage cabinets, power cabinets, air conditioning cabinets, etc., usually install sealing strips between the cabinet body and the cabinet door for waterproof and dustproofing.

The direct impact of rainwater on the sealing strip installed between the cabinet body and the cabinet door can easily cause sealing failure. In addition, when the cabinet door is large in size, the flatness of the sealing strip is difficult to ensure, resulting in uneven contact between the cabinet door and the sealing strip, causing waterproof failure. If rainwater enters the cabinet through the gap between the cabinet, there is a risk of affecting the internal components of the cabinet. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0032] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may be an intermediate component. When a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be an intermediate component.

[0033] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used in this application includes any and all combinations of one or more of the relevant listed items.

[0034] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0035] See also Figure 1 The present application provides an energy storage device 1000 , which includes a cabinet 100 , and the cabinet 100 is used to protect internal electrical components.

[0036] In the first embodiment, see Figure 1 and Figure 2The cabinet 100 includes a cabinet body 10, a cabinet door 20 and a first rubber strip 30. The cabinet body 10 is the main body of the cabinet 100 and is used to accommodate and protect the electrical components inside. The cabinet body 10 is sturdy in design and can withstand certain external impacts and pressures. The cabinet door 20 is rotatably connected to the cabinet body 10 and can rotate relative to the cabinet body 10 to open or close the cabinet body 10. The first rubber strip 30 is located between the cabinet body 10 and the cabinet door 20. When the cabinet door 20 is closed, the first rubber strip 30 is squeezed by the cabinet door 20 and the cabinet body 10, so that it fits tightly between the surfaces of the two. This tightly fitting state can effectively seal the gap between the cabinet body 10 and the cabinet door 20, preventing the intrusion of moisture and dust, so that the cabinet 100 can achieve excellent waterproof and dustproof effects. Even in harsh outdoor environments, the electrical components inside the cabinet 100 can be well protected to ensure their normal operation, thereby improving the reliability and safety of the energy storage device 1000.

[0037] When cabinet 100 is used in an energy storage device, the cabinet body 10 houses batteries. Multiple batteries can be stacked within the cabinet body 10. A first rubber strip 30 seals the gap between the cabinet door 20 and the cabinet body 10, reducing the risk of rainwater entering the cabinet 100. It should be understood that this application is not limited to the use of the cabinet 100 assembly in energy storage devices 1000. The cabinet 100 assembly can also be used in other fields, such as the power and communications fields. The cabinet 100 can be used to house power modules, power distribution modules, air conditioning modules, and the like.

[0038] The first adhesive strip 30 is a sealing strip 30 a made of a soft and durable material, so that it can be deformed and closely fit the surface of the cabinet door 20 when squeezed.

[0039] See also Figures 2 to 5 The sealing strip 30a includes a mounting portion 31 and a sealing portion 32. A sealing edge 35 is formed on the outer surface of the sealing portion 32, which protrudes away from the cavity 34. When the door is closed, the sealing edge 35 fits with the inner side of the cabinet door 20 to form a maze structure. The sealing strip 30a and the sealing edge 35 can undergo a certain deformation, so that the sealing strip 30a, the sealing edge 35 and the cabinet door 20 form a tighter fit, thereby improving the sealing effect.

[0040] The mounting portion 31 and the sealing portion 32 define a cavity 34; the sealing edge 35 protrudes away from the cavity 34. When the cabinet door 20 is closed, the sealing strip 30a is squeezed by the cabinet door 20 and the cabinet body 10. At this time, the cavity 34 provides a certain elastic buffer space for the sealing strip 30a, allowing the sealing strip 30a to deform to a certain extent, thereby better adapting to gaps of different sizes and shapes. Furthermore, the air within the cavity 34 is compressed, which increases the contact pressure between the sealing strip 30a, the cabinet door 20, and the cabinet body 10, forming a tighter fit between the sealing strip 30a and the cabinet door 20 and improving the sealing effect.

[0041] In one embodiment, the sealing portion 32 protrudes in a direction away from the mounting portion 31 to form an annular structure. The sealing portion 32 is connected to the mounting portion 31 at both ends along its circumference to enclose a cavity 34, allowing the sealing strip 30a to deform to a certain extent.

[0042] In other embodiments, a cavity 34 may be formed in the sealing portion 32. The sealing portion 32 is annular in shape, and the outer wall of the sealing portion 32 is connected to the mounting portion 31. This application does not limit this.

[0043] It should be noted that the number of sealing edges 35 can be two, three, or even more. Multiple sealing edges 35 can provide multiple sealing functions, enhancing the sealing effect. The number of sealing edges 35 can be increased based on specific application scenarios and requirements, and this application does not impose any restrictions. This flexibility allows the sealing strip 30a to adapt to different waterproofing requirements and environmental conditions.

[0044] The outer surface of the mounting portion 31 forms at least one side wing 33 protruding outward, and the side wing 33 is inclined toward the gap between the cabinet body 10 and the cabinet door 20 of the cabinet 100 in a direction away from the sealing portion 32; when the mounting portion 31 is fixed on the cabinet body 10, the side wing 33 overlaps the sheet metal surface of the cabinet body 10, greatly reducing the risk of water entering the cabinet through the gap between the mounting portion 31 and the cabinet body 10.

[0045] This embodiment is described using as an example three sealing edges 35 formed on the outer surface of the sealing portion 32, projecting away from the cavity 34. The three sealing edges 35 are a first sealing edge 351, a second sealing edge 352, and a third sealing edge 353. When the sealing strip 30a contacts the cabinet door 20, the side of the sealing strip 30a that communicates with the interior space of the cabinet body 10 is the inner side, and the side of the sealing strip 30a that communicates with the exterior space is the outer side.

[0046] Understandably, see Figure 2 、 Figure 3 and Figure 5The sealing portion 32 is an upwardly arched arc structure, the second sealing edge 352 tends to be set at the vertex of the sealing portion 32, the first sealing edge 351 and the second sealing edge 352 are both inclined outward, and the third sealing edge 353 is inclined inward. In this application, the inclination of the gap between the cabinet body 10 and the cabinet door 20 toward the cabinet 100 is inclined outward, and the inclination of the gap between the cabinet body 10 and the cabinet door 20 away from the cabinet 100 is inclined inward. Furthermore, the heights of the ends of the second sealing edge 352, the third sealing edge 353, and the first sealing edge 351 decrease in sequence. Therefore, when closing the cabinet door 20, the end of the second sealing edge 352 first contacts the end of the second sealing edge 352, pushing the top of the sealing portion 32 downward, thereby causing the first sealing edge 351 and the third sealing edge 353 to adjust their angles. Specifically, the first sealing edge 351 rotates a certain angle, and the third sealing edge 353 rotates outward a certain angle, so that the first sealing edge 351 and the third sealing edge 353 tend to further press against the cabinet door 20, thereby enhancing the sealing performance. As the end of the second sealing edge 352 moves downward, the cabinet door 20 can eventually simultaneously press against the ends of the first sealing edge 351, the second sealing edge 352, and the third sealing edge 353 to achieve multi-stage sealing.

[0047] In a specific implementation, the angle between the first sealing edge 351 and the second sealing edge 352 ranges from 14° to 24°. This prevents the first sealing edge 351 and the second sealing edge 352 from being parallel and affecting the sealing effect, or prevents the first sealing edge 351 from having an excessively large angle with the second sealing edge 352, which could make it difficult for the first sealing edge 351 to contact the cabinet door 20. The angle between the first sealing edge 351 and the second sealing edge 352 can be 19°. Similarly, the third sealing edge 353 and the second sealing edge 352 have opposite inclinations. It should be noted that these opposite inclinations do not mean that the third sealing edge 353 and the second sealing edge 352 are 180° apart. Rather, the second sealing edge 352 is inclined outward, while the third sealing edge 353 is inclined inward. The angle between the third sealing edge 353 and the second sealing edge 352 ranges from 97° to 117°. The angle between the third sealing edge 353 and the second sealing edge 352 can be 107°.

[0048] The side wing 33 is the part of the sealing strip 30a that contacts the installation surface (such as the frame of the cabinet 10). The side wing 33 is located on the outside of the installation portion 31, and the angle formed by the side wing 33 and the outer surface of the installation portion 31 is in the range of [27°, 45°]. If the angle is too small, it may cause the side wing 33 to be difficult to form a tight fit with the installation surface during installation, affecting the installation stability; if the angle is too large, it may increase the difficulty of installation and may cause the sealing strip 30a to be excessively deformed after installation, affecting the sealing effect. Within this range, it can be ensured that the sealing strip 30a can be stably fitted to the installation surface during installation and is not easy to loosen or shift. 37° can be used in practical applications.

[0049] The angle formed between the wing 33 and the outer surface of the mounting portion 31 can also be fine-tuned based on the specific installation environment and requirements. For example, a smaller angle range can be selected when higher sealing performance is required, while a larger angle range can be selected when greater installation stability is required.

[0050] The porosity of the sealing portion 32 is greater than that of the mounting portion 31. The primary function of the sealing portion 32 is to prevent the penetration of foreign substances such as gas, liquid, or dust, and therefore requires higher sealing performance. A higher porosity means more pores within the material of the sealing portion 32, which may be used to absorb or store lubricants to enhance sealing performance. Certain rubber or elastomer materials may be used for the sealing portion 32, potentially exhibiting higher porosity while still maintaining sufficient strength and elasticity to meet sealing requirements. The sealing portion 32 may also undergo special treatment or processing to increase its porosity. For example, the porosity can be altered by increasing the number or size of pores within the material through foaming or the addition of fillers. The mounting portion 31's primary function is to secure and support the sealing strip 30a, and therefore may require higher strength and stability. A lower porosity means fewer pores within the material of the mounting portion 31, which helps improve its strength and stability. Furthermore, the mounting portion 31 may not require the same high sealing performance as the sealing portion 32, so a material with a lower porosity can be used to reduce cost and manufacturing difficulty.

[0051] Specifically, the mounting portion 31 may be made of sealant to provide greater hardness, thereby facilitating a stable connection between the mounting portion 31 and the cabinet 10. The sealing portion 32 may be made of sponge rubber, the softness and sealing properties of which ensure close contact with the sealed surface, effectively preventing the penetration of air, moisture, or other substances.

[0052] See also Figure 2 and Figure 3 The mounting portion 31 includes a clamping groove 311 and clamping teeth 312 protruding from the inner wall of the clamping groove 311. The clamping groove 311 allows for partial insertion of the cabinet 10. The clamping teeth 312 on the inner wall can abut against the inserted portion of the cabinet 10, increasing friction with the cabinet 10 and preventing the sealing strip 30a from slipping or falling off during use. The protruding design of the clamping teeth 312 also ensures close contact with the cabinet 10, forming a stable connection.

[0053] The notch of the clamping groove 311 is located at the bottom and the clamping teeth 312 are inclined toward the top, so that the edge or structural part of the cabinet 10 can be easily inserted into the clamping groove 311 from bottom to top. Once the partial structure of the cabinet 10 is inserted into the clamping groove 311, since the clamping teeth 312 are inclined toward the top, the clamping teeth 312 will gradually tighten when the cabinet 10 is inserted and tightly clamp the partial structure of the cabinet 10. This inclined design increases the friction between the clamping teeth 312 and the cabinet 10, thereby improving the stability of the connection. In addition, when the clamping teeth 312 are subjected to outward pulling force, an inward reaction force will be generated. This reaction force will help resist the tendency of the cabinet 10 to slide out of the clamping groove 311. Therefore, even when subjected to a certain external force, the connection between the sealing strip 30a and the cabinet 10 can remain stable and not easily fall off.

[0054] The inner wall of the clamping groove 311 includes a first side wall 313 and a second side wall 314 that are arranged opposite to each other; the two clamping teeth 312 in each pair of clamping teeth 312 are respectively arranged on the first side wall 313 and the second side wall 314 and are arranged facing each other. The two clamping teeth 312 facing each other will act on both sides of the cabinet 10 at the same time, increasing the contact area with the cabinet 10 while also improving the friction, thereby providing a stronger clamping force and a more stable fixing effect. In addition, because the clamping teeth 312 are arranged facing each other, they can adapt to cabinet 10 structures of different thicknesses or shapes. This design makes the sealing strip 30a more versatile and adaptable, and can adapt to a wider range of usage scenarios.

[0055] The mounting portion 31 includes a frame 37, which is embedded in the mounting portion 31. The frame 37 is usually made of a strong material, such as metal or hard plastic, and can provide strong support for the mounting portion 31. This support can prevent the mounting portion 31 from being easily deformed or damaged when subjected to external forces, thereby extending its service life. Based on the frame 37, the frame 37 is U-shaped, and the mounting portion 31 is wrapped around the periphery of the frame 37 to form a clamping groove 311. In the finished product, the frame 37 is connected to the mounting portion 31 in an embedded form, and the frame 37 and the mounting portion 31 form a tight whole. This design can reduce the shaking or loosening of the mounting portion 31 during use, thereby improving its stability.

[0056] The edge of the cabinet body 10 forms an opening, which is covered by the cabinet door 20 when closed. A connecting plate 11 is provided at the edge of the cabinet body 10, parallel to the cabinet door 20. The edge of the connecting plate 11 is bent toward the cabinet door 20 to form a mounting flange 12. The mounting flange 12 can be inserted into the clamping groove 311 of the mounting portion 31, thereby achieving a stable connection between the cabinet door 20 and the cabinet body 10. This mounting flange 12 is integral with the cabinet body 10, which can improve sealing performance.

[0057] The length of the bent edge is just enough to make the side wing 33 of the first rubber strip 30 fit closely with the connecting plate 11 so as to achieve the effect of physical structural sealing and fitting and sealing between the rubber strip and the cabinet door 20 .

[0058] In other embodiments, it is sufficient to provide a mounting flange 12 extending toward the cabinet door 20 on the cabinet body 10. The mounting flange 12 can be connected to the cabinet body 10 by welding, bolt fastening, etc., and this application does not limit this.

[0059] The cabinet door 20 has a flange 21 extending toward the cabinet body 10. When the cabinet door 20 closes the cabinet body 10, the flange 21 is positioned outside the first rubber strip 30. The flange 21 forms an additional physical barrier, narrowing the gap between the cabinet door 20 and the cabinet body 10 when closed. This reduces the amount of rainwater that enters between the cabinet door 20 and the connecting plate 11, preventing excessive rainwater from impacting the first rubber strip 30 and protecting the integrity and sealing effect of the first rubber strip 30.

[0060] Please refer again Figure 1 and Figure 2 A baffle 40 is provided on the top of the cabinet body 10. When the cabinet door 20 closes the cabinet body 10, the edge of the baffle 40 is flush with the cabinet door 20 or protrudes from the cabinet door 20. Since rainwater generally tends to fall from top to bottom, or forms a certain inclination angle under the influence of wind, when the baffle 40 blocks the gap between the cabinet door 20 and the cabinet body 10, rainwater is effectively guided to the outside of the cabinet body 10 instead of falling directly into the gap between the cabinet door 20 and the cabinet body 10, thereby effectively reducing the intrusion of rainwater and the possibility of other foreign matter such as dust and small insects entering the cabinet body 10.

[0061] In summary, in the first embodiment, the flange 21 of the cabinet door 20 forms the first layer of protection, the side wing 33 of the first rubber strip 30 abuts against the connecting plate 11 to form the second layer of protection, the mounting fold 12 and the clamping teeth 312 form the third layer of protection, and the sealing edge 35 on the outside of the sealing part 32 fits against the inside of the cabinet door 20 to form the fourth layer of protection, which can meet the IP66 cabinet protection design.

[0062] IP66 is a dust and water resistance rating standard drafted and developed by the International Electrotechnical Commission (IEC), also known as Ingress Protection Rating (IP protection rating) or international protection rating. This standard is developed to define how electrical equipment and casings prevent the intrusion of foreign objects and waterproof performance. The first number "6" represents the dustproof level, which means that dust is completely prevented from entering, that is, the cabinet 10 is in a completely closed state and no dust enters. The second number "6" represents the waterproof level, which means that the cabinet 10 can withstand strong water spray from any direction, such as heavy rain or short-term immersion in water without causing harmful effects. Specifically, the equipment can still work normally without water infiltration when it is 2.5-3 meters away from the water nozzle, receives water spray for at least 3 minutes, and the water pressure is not less than 100kPa (equivalent to 1 bar).

[0063] In the second embodiment, if Figure 6 As shown, the difference from the first embodiment is that the cabinet 100 also includes a second rubber strip 50, which is connected to the cabinet door 20. The second rubber strip 50 is used to abut the cabinet body 10 when the cabinet door 20 closes the cabinet body 10, and the second rubber strip 50 is located outside the first rubber strip 30. Based on the first embodiment, the second embodiment can add a layer of protection between the first and second layers of protection (the second rubber strip 50 is tightly attached to the connecting plate 11), forming a five-layer protection, further improving the waterproof and dustproof effects.

[0064] The second rubber strip 50 can be provided with a built-in fixing nail 61. The fixing nail 61 can be a rubber nail, which is then attached to the inside of the cabinet door 20. Alternatively, a hollow rubber strip can be affixed to the inside of the cabinet door 20 to provide additional waterproofing and dustproofing for the cabinet 100. The hollow rubber strip deforms and contracts to conform to the cabinet body 10 frame. The second rubber strip 50 can also be formed of other sealing strips or connected to the cabinet door 20 by other means, as this application is not limited thereto.

[0065] By installing the first and second rubber strips 30 and 50 on the cabinet body 10 and door 20, respectively, a dual seal is achieved. The first rubber strip 30 provides the primary seal, while the second rubber strip 50 acts as a secondary seal, further reducing gaps and the possibility of infiltration. This design provides a better seal in a variety of environmental conditions.
