Description

Technical Field

[0001] This utility model relates to the field of engine room cover technology, and in particular to a temperature-resistant injection-molded engine room cover with an anti-deformation structure. Background Technology

[0002] In the manufacturing of various equipment hull components, high-temperature injection molded covers serve as critical protective and structural parts, requiring long-term operation in complex environments of high temperature and vibration. However, their molding quality and durability have consistently presented significant challenges. Traditional molding processes, failing to systematically consider the coupling effects of multiple fields such as temperature, stress, and flow, result in poor dimensional stability of the molded covers under high-temperature conditions, making them prone to defects such as cracks and shrinkage marks. Furthermore, the lack of structural reinforcement measures for high-temperature operating conditions leads to insufficient bending strength and impact resistance under prolonged high-temperature stress, resulting in a high risk of fracture. Simultaneously, the failure to effectively address stress issues caused by thermal expansion and contraction makes the covers susceptible to warping deformation during use, not only compromising assembly accuracy with surrounding components but also shortening their overall service life. Utility Model Content

[0003] The purpose of this invention is to provide a cabin high-temperature resistant injection molded cover with an anti-deformation structure, in order to solve the defect that the existing cabin high-temperature resistant injection molded cover is not easy to prevent deformation.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cabin temperature-resistant injection molded cover plate with an anti-deformation structure, including a cover plate body;

[0005] An installation groove is provided in the middle of the interior of the cover plate body, and assembly holes are provided at the edges of the interior of the cover plate body. Reinforcing structures are provided on both sides of the cover plate body. Each reinforcing structure includes a first boss located on one side of the top of the cover plate body, with arc-shaped edges on both sides of the top of the first boss. Arc-shaped grooves are provided on the edges of both sides of the cover plate body on the side of the first boss. Through grooves are provided on both sides of the interior of the cover plate body. Flanges are fixed on both sides of the cover plate body. A connecting block is fixed on one side of the first boss. A second boss is provided on the bottom of the cover plate body away from the first boss. A first transverse reinforcing rib is fixed on one side of the second boss at the bottom of the cover plate body. A second transverse reinforcing rib is fixed on one side of the first transverse reinforcing rib. A longitudinal reinforcing rib is fixed between the first and second transverse reinforcing ribs. A reinforcing ridge is fixed on one side of the second transverse reinforcing rib.

[0006] The cover plate body has a protective structure inside.

[0007] Preferably, the mounting groove is arranged in a cross shape, and the mounting holes are symmetrically distributed at the edge positions inside the cover plate body.

[0008] With the above structure, the symmetrical distribution of the mounting holes on the edge of the cover plate body during use ensures that the stress points are symmetrically arranged when the cover plate is fixed to the cabin frame with bolts. This allows the preload generated by tightening the bolts to be evenly transmitted to various areas of the cover plate edge, avoiding local overload of the cover plate due to the offset of the stress points.

[0009] Preferably, the arc-shaped edges are symmetrically distributed on both sides of the top of the first protrusion, the arc-shaped grooves are symmetrically distributed on both sides of the cover plate body, and the through grooves are evenly distributed on both sides inside the cover plate body.

[0010] With the above structure, the symmetrically distributed arc edges can ensure that the force on both sides of the boss is balanced during use, while the symmetrical arc grooves on both sides can accommodate some deformation when the edge of the cover plate is heated and expanded, avoiding warping or cracking of the edge due to excessive stretching; and the symmetrical distribution ensures that the deformation on both sides of the cover plate is uniform, and the overall structure will not shift due to unbalanced deformation on one side.

[0011] Preferably, the flanges are symmetrically distributed on both sides of the first boss, and the connecting blocks are evenly distributed on one side of the first boss.

[0012] With the above structure, the symmetrically distributed flanges ensure that the sealing layer can evenly cover the assembly gap between the cover plate and the cabin frame during use. The connecting block can distribute the stress to the entire cover plate through a uniform force transmission path, avoiding material fatigue caused by local stress concentration and indirectly extending the service life of the cover plate.

[0013] Preferably, both ends of the first and second transverse reinforcing ribs are rounded, the thickness of the first and second transverse reinforcing ribs gradually decreases from both ends to the middle, the longitudinal reinforcing ribs are evenly distributed between the first and second transverse reinforcing ribs, the longitudinal reinforcing ribs are perpendicular to the first and second transverse reinforcing ribs, and the side view of the longitudinal reinforcing ribs is triangular.

[0014] The aforementioned structure, with its gradually varying thickness of transverse and longitudinal reinforcing ribs, resists the tendency for central depression caused by equipment pressure and high-temperature expansion during use. This gradient in the thermal deformation of the reinforcing ribs along the thickness direction better matches the thermal deformation trend of the cover plate itself, reducing internal stress caused by differences in thermal deformation and lowering the risk of overall warping and deformation. Furthermore, the perpendicular intersection and equal spacing of the longitudinal and transverse reinforcing ribs create a three-dimensional "grid" support structure at the bottom of the cover plate, preventing longitudinal bending and depression caused by localized overload. Simultaneously, the grid structure reduces the "suspended area" at the bottom of the cover plate, lowering the probability of deformation due to uneven heating under high-temperature conditions.

[0015] Preferably, the reinforcing ribs are evenly distributed on one side of the second transverse reinforcing rib, and the length of the reinforcing ribs gradually increases from both ends to the middle of the second transverse reinforcing rib.

[0016] With the above structure, the reinforcing ribs are designed with a gradually changing length of "short at both ends and long in the middle". This allows the longer reinforcing ribs in the middle to form a "strong support section", increasing the contact area with the bottom of the cover plate and improving the resistance to deformation in the high-stress area in the middle. The shorter reinforcing ribs at both ends, while meeting the basic support requirements, can flexibly adapt to the small thermal deformation at the edges, avoiding the restriction of normal thermal expansion and contraction of the cover plate edges due to excessive rigidity of the reinforcing ribs, and further reducing the risk of warping and cracking of the cover plate as a whole due to temperature fluctuations.

[0017] Preferably, the protective structure includes an outer cover plate disposed inside the cover plate body, an inner cover plate disposed on one side of the outer cover plate, a heat insulation interlayer disposed between the outer cover plate and the inner cover plate, a fireproof layer disposed on the outside of the heat insulation interlayer, a high-temperature resistant layer disposed on the side of the outer cover plate and the inner cover plate that are far apart from each other, a protective layer disposed on one side of the high-temperature resistant layer, and a sealing layer disposed on one side of the flange.

[0018] Preferably, the heat insulation interlayer is an aerogel felt, the fireproof layer is a flame-retardant PET film, the high-temperature resistant layer is an organosilicon high-temperature resistant coating, the protective layer is a fluorocarbon resin coating, and the sealing layer is an EPDM rubber foam layer.

[0019] With the above structure, the heat insulation interlayer and the high temperature resistant layer can work together to control the temperature and reduce the risk of deformation due to temperature difference during use. The fireproof layer and the protective layer can improve safety and durability, indirectly prevent the cover plate from deforming due to local high temperature, extend the overall service life of the cover plate, and fill gaps through the sealing layer to strengthen the overall protective closed loop.

[0020] The advantages of the cabin temperature-resistant injection-molded cover plate with anti-deformation structure provided by this utility model are as follows:

[0021] By incorporating a reinforced structure and combining transverse and longitudinal reinforcing ribs, the overall bending and tensile strength of the cover plate can be significantly improved, preventing central depression and edge warping caused by vibration or pressure during long-term use. The fit between the reinforcing ribs and bosses strengthens the bottom support of the cover plate and disperses local pressure. Even when bearing heavy equipment or being subjected to external impacts, the structure can remain intact, extending its service life. Furthermore, the symmetrical distribution of the arc-shaped edges and arc-shaped grooves can buffer local stress during assembly and vibration impact during engine room operation, reducing the risk of edge cracking.

[0022] By incorporating a protective structure, a "double protection" is formed through an aerogel felt insulation interlayer and a flame-retardant PET film fireproof layer. This not only blocks the transmission of external high temperatures inward but also resists open flame attacks, preventing the cover from aging and burning due to high temperatures. The dual coverage of the silicone high-temperature resistant coating and the fluorocarbon resin protective layer protects the outer cover from the effects of high external environmental temperatures and the inner cover from localized high temperatures of internal equipment. This effectively prevents the cover from structural deformation or material deterioration due to excessive temperature differences. Furthermore, the EPDM rubber sealing layer not only seals gaps but also prevents heat from penetrating through assembly gaps, further enhancing the overall temperature resistance.

[0029] 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.

[0030] Please see Figures 1-5 The present invention provides a cabin temperature-resistant injection molded cover plate with an anti-deformation structure, including a cover plate body 1.

[0031] Reference Figures 1-4 As shown, a mounting groove 2 is provided in the middle of the interior of the cover plate body 1, and mounting holes 3 are provided at the edges of the interior of the cover plate body 1. The mounting groove 2 is arranged in a cross shape, and the mounting holes 3 are symmetrically distributed at the edges of the interior of the cover plate body 1. Reinforcing structures 4 are provided on both sides of the cover plate body 1. The reinforcing structure 4 includes a first boss 401 located on one side of the top of the cover plate body 1. Arc-shaped edges 402 are provided on both sides of the top of the first boss 401, and arc-shaped grooves 403 are provided on the edges of both sides of the cover plate body 1 on the side of the first boss 401. Both sides of the inner surface of the plate body 1 are provided with through grooves 404, and both sides of the cover plate body 1 are fixed with flanges 405. A connecting block 406 is fixed to one side of the first boss 401. A second boss 407 is provided on the bottom end of the cover plate body 1 away from the first boss 401. A first transverse reinforcing rib 408 is fixed to one side of the second boss 407 at the bottom end of the cover plate body 1, and a second transverse reinforcing rib 409 is fixed to one side of the first transverse reinforcing rib 408. A longitudinal reinforcing rib 410 is fixed between the first transverse reinforcing rib 408 and the second transverse reinforcing rib 409. A reinforcing rib 411 is fixed to one side of the transverse reinforcing rib 409. Arc-shaped edges 402 are symmetrically distributed on both sides of the top of the first boss 401. Arc-shaped grooves 403 are symmetrically distributed on both sides of the cover plate body 1. Through grooves 404 are evenly distributed on both sides inside the cover plate body 1. Flanged edges 405 are symmetrically distributed on both sides of the first boss 401. Connecting blocks 406 are evenly distributed on one side of the first boss 401. Both ends of the first transverse reinforcing rib 408 and the second transverse reinforcing rib 409 are rounded. The first transverse reinforcing rib 408 and the second transverse reinforcing rib 409... The thickness of the two transverse reinforcing ribs 409 gradually decreases from both ends to the middle. The longitudinal reinforcing ribs 410 are evenly distributed between the first transverse reinforcing ribs 408 and the second transverse reinforcing ribs 409. The longitudinal reinforcing ribs 410 are perpendicular to the first transverse reinforcing ribs 408 and the second transverse reinforcing ribs 409. The side view of the longitudinal reinforcing ribs 410 is triangular. The reinforcing ribs 411 are evenly distributed on one side of the second transverse reinforcing ribs 409. The length of the reinforcing ribs 411 gradually increases from both ends to the middle of the second transverse reinforcing ribs 409.

[0032] The arc-shaped grooves 403 on both sides of the cover plate body 1 can buffer assembly stress and prevent edge cracking. The equally spaced through grooves 404 on both sides inside the cover plate can reduce the overall weight of the cover plate and form an air circulation channel to assist heat dissipation and reduce the performance degradation of the cover plate caused by long-term high temperature accumulation. The equally spaced connecting blocks 406 ensure the connection strength of the cover plate. The first transverse reinforcing rib 408 and the second transverse reinforcing rib 409 at the bottom of the cover plate are both designed with "gradual thickness", thick in the middle and thin at both ends. This ensures the support strength of the middle area and absorbs the deformation force generated by vibration through the flexible structure at both ends. The triangular longitudinal reinforcing ribs 410 distributed vertically between the two further enhance the bending resistance of the transverse ribs, while the equally spaced reinforcing ribs 411 can disperse the local pressure at the bottom and prevent the bottom from sinking.

[0033] Reference Figure 5 As shown, a protective structure 5 is provided inside the cover plate body 1. The protective structure 5 includes an outer cover plate 501 disposed inside the cover plate body 1, an inner cover plate 502 disposed on one side of the outer cover plate 501, a heat insulation interlayer 503 disposed between the outer cover plate 501 and the inner cover plate 502, a fireproof layer 504 disposed on the outside of the heat insulation interlayer 503, a high temperature resistant layer 505 disposed on the side of the outer cover plate 501 and the inner cover plate 502 that are far apart from each other, a protective layer 506 disposed on one side of the high temperature resistant layer 505, and a sealing layer 507 disposed on one side of the flange 405. The heat insulation interlayer 503 is an aerogel felt, the fireproof layer 504 is a flame-retardant PET film, the high temperature resistant layer 505 is an organosilicon high temperature resistant coating, the protective layer 506 is a fluorocarbon resin coating, and the sealing layer 507 is an EPDM rubber foam layer.

[0034] The aerogel felt insulation layer 503 between the outer cover plate 501 and the inner cover plate 502 effectively blocks the transmission of external high temperature to the interior of the cover plate, reducing structural deformation caused by excessive temperature difference between the inside and outside. The flame-retardant PET film fireproof layer 504 on the outside of the insulation layer can prevent flames from directly contacting the internal structure. Even if there is an open flame outside, it can delay the spread of the flame and prevent the cover plate from being damaged by high temperature combustion. The high temperature resistant layer 505 on the outside of the outer cover plate 501 and the inner cover plate 502 is an organosilicon high temperature resistant coating, which can withstand high temperature environment and prevent the cover plate from aging and cracking due to high temperature. The protective layer 506 is a fluorocarbon resin coating, which can resist the local high temperature generated by the equipment inside the cabin and protect the stability of the inner plate structure. The sealing layer 507 on one side of the flange 405 on both sides of the cover plate is a EPDM rubber foam layer, which can fill the gap between the cover plate and the cabin during assembly, preventing external dust and liquid from entering and further blocking heat transfer at the gap, thus improving the overall temperature resistance.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
