A light new energy equipment shell heat preservation layer structure

Abstract

This utility model provides a lightweight insulation layer structure for the outer shell of new energy equipment, belonging to the field of new energy equipment protection technology. It includes a lightweight shell, in which a lightweight base layer, a low-weight composite insulation layer, and a protective layer are sequentially fixed from the inside out within the lightweight shell's inner cavity. A docking chamber is formed between the semi-groove cavity and the low-weight composite insulation layer. Pre-connecting components within the docking chamber allow adjacent insulation layer structures to be joined together, and then fixed to the outside of the new energy equipment. Through the lightweight design of each component and the assembly of the pre-connecting components, the installation of the insulation layer structure on the new energy equipment is more convenient. The protruding ridges increase the space occupied by the low-weight composite insulation layer while reducing the space occupied by the lightweight base layer. Furthermore, the low-weight composite insulation layer is lighter than the lightweight base layer, thus achieving a weight reduction effect for the overall insulation layer structure, making it more portable.

Description

Technical Field

[0001] This utility model relates to the field of new energy equipment protection technology, specifically a lightweight new energy equipment shell insulation layer structure. Background Technology

[0002] The stable operation of new energy equipment is highly dependent on a suitable operating temperature environment. Low temperatures can lead to battery capacity decay and reduced energy storage efficiency, while high temperatures may cause thermal runaway and component aging. Therefore, the outer shell insulation layer has become a key component to ensure the performance and lifespan of the equipment.

[0003] The following problems were found in the relevant technologies: the pain points of traditional new energy equipment shell insulation layers in terms of weight, installation, structure and protection have seriously restricted the performance improvement and portability of new energy equipment. The many technical pain points are difficult to adapt to the development requirements of modern new energy equipment. In response, we have proposed a lightweight new energy equipment shell insulation layer structure.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the issue of lightweight insulation layers in the prior art, this utility model provides a lightweight insulation layer structure for the outer shell of new energy equipment. This structure employs a layered, overlapping, and pre-connected structure for adjacent insulation layers to facilitate construction. The specific technical solution is as follows: A lightweight new energy equipment shell insulation layer structure includes a lightweight shell. The inner cavity of the lightweight shell is sequentially fixed with a lightweight base layer, a low-weight composite insulation layer, and a protective layer from the inside to the outside. The protective layer has a semi-groove cavity on its side wall, and the semi-groove cavity and the low-weight composite insulation layer form a docking chamber. The docking chamber is provided with a pre-connection component for splicing with the adjacent insulation layer. The low-weight composite insulation layer has protruding ridges evenly arranged on the side near the lightweight base layer. The side wall of the lightweight base layer has weight-reducing grooves that interlock with all the protruding ridges.

[0006] In the above technical solution, the operating end of the pre-connected component extends out of the lightweight housing after penetrating the protective layer, and the outer wall of the lightweight housing is provided with a splicing clearance groove for hiding the operating end of the pre-connected component.

[0007] The pre-connection assembly includes a connector that is slidably disposed inside the docking chamber, and the lightweight cover has an insertion hole on the side away from the connector that is inserted into the connector. The protective layer has a pre-connection drive member with an operating end extending to the outside of the lightweight cover, and the output end of the pre-connection drive member is connected to the connector through a transmission member.

[0008] The pre-connected drive component includes a drive shaft threadedly connected to the inner cavity of the protective layer, and the drive shaft passes through the side wall of the lightweight housing and extends to the outside.

[0009] The length of the drive shaft extending outward corresponds to the depth of the insertion hole, and an operating wheel that fits into the splicing clearance groove is sleeved on the outer wall of one end of the drive shaft outside the lightweight cover.

[0010] The transmission component includes a linkage frame for connecting two plug-in parts, and the linkage frame is located inside the lightweight housing. The linkage frame is rotatably connected to the drive shaft via a universal joint.

[0011] The universal joint includes a universal base fixed to the end of the drive shaft, and a steering component movably embedded inside the universal base is fixedly installed on the linkage frame.

[0012] The lightweight casing has sliders and grooves on both sides of its outer wall for splicing.

[0013] The docking chamber is equipped with lightweight reinforcing ribs.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The interlocking of the raised ribs of the low-weight composite insulation layer and the weight-reducing grooves of the lightweight base layer ensures the stability of the connection between the two while reducing the amount of material used in the lightweight base layer (the weight-reducing grooves reduce the base layer material by 15%-20%). In addition, the raised ribs of the insulation layer are made of lightweight insulation material, which reduces the weight by 40%-50% compared with the base layer material of the same volume, further achieving weight reduction without compromising stability.

[0015] Second, the connectors in the docking chamber achieve synchronous extension and retraction through pre-connected drive components (drive shaft + linkage frame). Twisting the drive shaft can drive the two connectors to be inserted into the insertion holes of adjacent insulation layers. A single person can complete the operation of a single splicing point within 1 minute. Taking energy storage equipment as an example, the installation time of the insulation layer of a single device is shortened to less than 1 hour, and no mechanical hoisting is required, reducing installation costs.

[0016] Third, the drive shaft operating end is hidden by the splicing groove. After splicing, the operating wheel fits into the surface of the lightweight cover, with no exposed parts. On the one hand, it avoids external environmental corrosion and extends service life; on the other hand, it achieves seamless splicing, reduces heat leakage rate to below 5%, improves insulation efficiency by 25%-30%, and has a neat appearance, meeting the requirements of integrated design.

[0017] Fourth, the lightweight casing integrates a lightweight base layer, a low-weight composite insulation layer, and an ultra-thin protective layer, resulting in an overall insulation layer weight of ≤4.85kg per square meter, which is more than 60% lighter than the traditional rock wool + sheet metal insulation structure. The weight of the insulation layer in portable energy storage equipment can be controlled below 5kg, making it easy for a single person to carry and offering a portability advantage.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The following are specific implementation cases and appendices. Figure 1-5The present invention will be further described below, but the present invention is not limited to these embodiments.

[0021] A lightweight new energy equipment shell insulation layer structure includes a lightweight shell 1. The inner cavity of the lightweight shell 1 is sequentially fixed with a lightweight base layer 2, a low-weight composite insulation layer 3, and a protective layer 4 from the inside to the outside. The lightweight base layer 2, which is close to the shell of the new energy equipment, is made of a high-strength lightweight plastic board such as PP / ABS composite board with a density of ≤1.2g / cm³, a thickness of 1-3mm, and a weight of ≤3.6kg per square meter. The low-weight composite insulation layer 3 consists of, from the inside out, an aerogel felt layer with a density ≤150g / m² and a thickness of 2-5mm; a vacuum insulation board core material with a density ≤30kg / m³ and a thickness of 3-8mm, and a vacuum degree ≤1Pa; and a low-density polyurethane foam layer with a density of 30-60kg / m³, a thickness of 5-10mm, and a foam pore diameter of 0.5-1mm. The overall weight per square meter is ≤1.2kg. The protective layer 4 uses a polyurea coating with a solid content ≥95%, formed by high-pressure airless spraying, with a thickness of 1-3mm and a weight per square meter of ≤0.05kg. This makes the overall insulation layer structure weigh ≤4.85kg per square meter, which is more than 60% lighter than the traditional rock wool + sheet metal insulation structure.

[0022] The lightweight casing 1 is bonded to the outer shell of the new energy equipment using an environmentally friendly lightweight strong adhesive with a solid content of ≥80% and a density of ≤1.0g / cm³ after curing, with an adhesive consumption of ≤100g per square meter; the layers of the low-weight composite insulation layer are bonded to each other using a low-viscosity, high-temperature resistant adhesive with a density of ≤0.9g / cm³, with an adhesive consumption of ≤80g per square meter.

[0023] A semi-groove cavity 5 is formed on the side wall of the protective layer 4, and a docking chamber 6 is formed between the semi-groove cavity 5 and the low-weight composite insulation layer 3. A semi-groove cavity 5 occupying half a plane is formed on the side of the protective layer 4 facing the low-weight composite insulation layer 3, thus forming a docking chamber 6 between the semi-groove cavity 5 and the low-weight composite insulation layer 3. The docking chamber 6 contains pre-connection components for splicing with adjacent insulation layers. These pre-connection components allow for splicing between the lightweight casing 1 containing two adjacent insulation layer structures, which are then securely fixed to the exterior of the new energy equipment. The lightweight design of each component and the splicing of the pre-connection components make the installation of the insulation layer structure of the new energy equipment more convenient.

[0024] The low-weight composite insulation layer 3 has evenly distributed protruding ribs 7 on the side near the lightweight base layer 2, and the side wall of the lightweight base layer 2 has evenly distributed weight-reducing grooves 8 that interlock with all the protruding ribs 7. The protruding ribs 7 increase the space occupied by the low-weight composite insulation layer 3, while reducing the space occupied by the lightweight base layer 2. Moreover, the low-weight composite insulation layer 3 is lighter than the lightweight base layer 2, thus achieving a weight reduction effect for the overall insulation layer structure, making the whole structure lighter.

[0025] The operating end of the pre-connected component extends through the protective layer 4 and out of the lightweight housing 1. The outer wall of the lightweight housing 1 is provided with a splicing clearance groove 9 for concealing the operating end of the pre-connected component. Through the design of the splicing clearance groove 9, the drive shaft 12, after operation, can be housed inside the splicing joint when splicing with adjacent insulation layer structures, achieving a seamless connection between the insulation layer structures and ensuring the protective effect.

[0026] The pre-connection assembly includes a connector 10 that is slidably positioned inside the docking chamber 6, and a socket 11 for interlocking with the connector 10 is provided on the side of the lightweight cover 1 away from the connector 10. Two supports are fixedly installed on the inner wall of the semi-groove 5, and each support has a through hole penetrating the inner cavity. The connector 10 can be inserted into the support, allowing it to slide on the support. The two connectors 10 slide parallel to each other inside the docking chamber 6. A through hole corresponding to the connector 10 is provided on the outer wall of the lightweight cover 1, allowing the connector 10 to pass through the through hole and be inserted into the socket 11 on the adjacent insulation layer structure, thereby achieving the splicing between two adjacent insulation layer structures.

[0027] The protective layer 4 has a pre-connected drive member with an operating end extending to the outside of the lightweight cover 1, and the output end of the pre-connected drive member is connected to the plug-in 10 through a transmission member. The pre-connected drive member enables the transmission member to drive the two plug-in 10 to simultaneously pass through the lightweight cover 1 from inside the protective layer 4 and insert into the socket 11 on the adjacent insulation layer structure.

[0028] The pre-connected drive component includes a drive shaft 12 that is threaded into the inner cavity of the protective layer 4. The drive shaft 12 passes through the side wall of the lightweight cover 1 and extends to the outside. The outer wall of the drive shaft 12 is provided with a partial external thread, and the inner cavity of the protective layer 4 is provided with a threaded through hole, so that the drive shaft 12 is threadedly connected to the protective layer 4.

[0029] It is worth noting that the length of the drive shaft 12 extending outward corresponds to the depth of the insertion hole 11, and an operating wheel that fits into the splicing clearance groove 9 is sleeved on the outer wall of the end of the drive shaft 12 located outside the lightweight cover 1. When the operating wheel is turned outside the lightweight cover 1, the distance between the operating wheel and the lightweight cover 1 is the same as the depth of the insertion hole 11. After the drive shaft 12 drives the connector 10 to be inserted into the insertion hole 11 through the linkage frame 13, the operating wheel is now in contact with the surface of the lightweight cover 1.

[0030] Furthermore, the transmission component includes a linkage frame 13 for connecting the two connectors 10, and the linkage frame 13 is located inside the lightweight housing 1. The linkage frame 13 is rotatably connected to the drive shaft 12 via a universal joint. Both ends of one side of the linkage frame 13 are fixedly connected to the ends of the two connectors 10 located inside the lightweight housing 1. A spherical steering member 15 is fixedly mounted on the other side of the linkage frame 13 via a support column. One side of the outer wall of the universal joint 14 is fixed to one end of the drive shaft 12 extending into the docking chamber 6. The other side of the outer wall of the universal joint 14 has a spherical groove corresponding to the shape of the steering member 15, allowing the steering member 15 to rotate inside the universal joint 14.

[0031] The universal joint includes a universal carrier 14 fixed to the end of the drive shaft 12, and a steering component 15 movably embedded inside the universal carrier 14 is fixedly installed on the linkage frame 13.

[0032] In addition, the outer walls of the lightweight casing 1 are respectively provided with sliders 16 and grooves 17 for splicing. The sliders 16 and grooves 17 make it easier to splice two adjacent insulation layer structures.

[0033] Furthermore, the interior of the docking chamber 6 is provided with lightweight reinforcing ribs 18. The lightweight reinforcing ribs 18 are provided inside the docking chamber 6 through a molding process. The miniature lightweight reinforcing ribs 18 provide support for the interior of the docking chamber 6 and improve the overall stability.
