Description

Technical Field

[0001] This utility model relates to the field of engine cover technology, and in particular to a dustproof and waterproof sealed engine cover. Background Technology

[0002] In today's rapidly developing automotive industry, the engine, as the "heart" of a car, is directly affected by the quality of its operating environment, impacting vehicle power performance, reliability, and lifespan. During daily urban commutes, frequent starts and stops cause road dust to accumulate, and rainwater kicked up by wheels directly impacts the engine compartment. However, traditional engine covers lack a sealing structure, allowing external dust and rainwater to easily enter through the gaps between the cover and the engine compartment, adhering to the surfaces of engine components, accelerating wear and aging, reducing engine efficiency, and even causing malfunctions. Furthermore, traditional engine covers have limited structural strength and are prone to deformation under impact or pressure, failing to effectively protect components within the engine compartment. Therefore, we have introduced a dustproof and waterproof sealed engine cover. Utility Model Content

[0003] The main objective of this invention is to provide a dustproof and waterproof sealed engine cover, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A dustproof and waterproof sealed engine cover includes a first fixing plate and a second fixing plate. The upper ends of the first fixing plate and the second fixing plate are both provided with through fixing holes. A sealing component is fixedly connected between the first fixing plate and the second fixing plate. A protective component is sleeved on the upper end of the sealing component. Bolts are threaded to the four corners of the upper end of the protective component.

[0006] Preferably, the sealing assembly includes a base plate, a sealing gasket is fixedly connected to the upper edge of the base plate, a sealing ring is fixedly sleeved inside the sealing gasket, positioning sleeves are fixedly connected to the four corners of the upper part of the base plate, and the upper ends of the four positioning sleeves are each provided with a first screw hole. The base plate is fixedly connected between a first fixing plate and a second fixing plate.

[0007] By adopting the above technical solution: the sealing gasket is made of "ethylene propylene diene monomer (EPDM) rubber", which can resist the corrosion of ultraviolet rays, rainwater and oil and gas in the engine compartment for a long time; the sealing ring is made of "hydrogenated nitrile butadiene rubber", which has excellent high temperature resistance, oil resistance and chemical corrosion resistance, effectively resisting the corrosion of engine oil and coolant, while maintaining good sealing elasticity.

[0008] Preferably, the protective component includes an aluminum alloy shell, an anti-deformation reinforcing rib is fixedly connected to the inner wall of the aluminum alloy shell, a flame-retardant inner shell is fixedly connected to the inner wall of the anti-deformation reinforcing rib, positioning sleeve holes are opened at the four corners of the lower end of the aluminum alloy shell, and second screw holes that pass through the inner and outer sides are opened at the four corners of the upper end of the aluminum alloy shell.

[0009] By adopting the above technical solution: the flame-retardant inner shell is made of polyetheretherketone, which can withstand the extreme high temperature environment of the engine compartment and can effectively block the spread of flames.

[0010] Preferably, the anti-deformation reinforcing rib is configured as a grid structure formed by interlacing several horizontal bars and several vertical bars.

[0011] By adopting the above technical solution: the anti-deformation reinforcing ribs of the grid structure formed by the interlacing of horizontal and vertical bars can quickly disperse the concentrated stress to the entire cover plate when the aluminum alloy shell is subjected to external impact, reducing stress concentration and effectively avoiding local deformation.

[0012] Preferably, the sealing gasket is located between the base plate and the aluminum alloy outer shell, and the sealing ring is fitted inside the flame-retardant inner shell.

[0013] By adopting the above technical solution: the sealing gasket is sandwiched between the base plate and the aluminum alloy shell, and forms a planar sealing barrier after being compressed, blocking external dust and moisture from entering through the gap between the base plate and the aluminum alloy shell. The sealing ring is fitted inside the flame-retardant inner shell, filling the internal gaps and forming a three-dimensional protection. The double defense improves the waterproof and dustproof effect and effectively isolates external pollutants.

[0014] Preferably, the four positioning sleeve rods are respectively fitted into the four corresponding positioning sleeve holes.

[0015] By adopting the above technical solution, the sleeve structure and bolt fastening form a "double insurance". Under the bumpy and vibrating environment of vehicle driving, the positioning sleeve and the sleeve hole are tightly engaged, which effectively restricts the relative displacement of the components, improves the vibration resistance of the cover plate connection, and ensures the reliability of long-term use.

[0016] Preferably, the outer surfaces of the four bolts are threaded to the inner walls of the corresponding four second screw holes and extend into the corresponding four first screw holes.

[0017] By adopting the above technical solution, the bolts pass through the second screw hole and the positioning sleeve in sequence and are screwed into the first screw hole, forming a coaxial triple constraint, so that the protective component and the sealing component can be reliably locked in the axial direction.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this utility model, the positioning sleeve hole of the protective component is connected to the positioning sleeve rod of the sealing component. The bolts are then screwed into the first screw hole through the second screw hole and the positioning sleeve hole in sequence to achieve fastening. As the bolts are tightened, the protective component presses down on the sealing component. The sealing gasket is squeezed and undergoes elastic deformation, tightly adhering to the lower end face of the aluminum alloy shell, forming an elastic barrier that blocks external dust and moisture outside the edge of the cover plate. At the same time, the sealing ring is squeezed by the flame-retardant inner shell, filling the gap between the sealing gasket and the flame-retardant inner shell, building a second sealing defense line. This effectively avoids engine failure due to poor heat dissipation caused by dust accumulation and short circuit caused by water vapor corrosion, extending the maintenance cycle and service life of the engine.

[0020] 2. In this utility model, the protective component adopts a composite design of an aluminum alloy shell, a mesh-like anti-deformation reinforcing rib, and a flame-retardant inner shell. After installation, the aluminum alloy shell, with its high strength and corrosion resistance, directly resists the impact of sand and gravel and the erosion of rainwater. Its smooth surface allows rainwater to slide off quickly, avoiding water accumulation and corrosion. When subjected to external impact, the mesh-like anti-deformation reinforcing rib, composed of interwoven horizontal and vertical bars, forms a sturdy skeleton that can evenly distribute the impact force to the entire aluminum alloy shell. Compared with traditional covers, the impact resistance is improved, effectively preventing dents and deformation. The flame-retardant inner shell fits tightly against the inner wall of the anti-deformation reinforcing rib. In the event of a sudden high temperature or open flame in the engine compartment, it can effectively exert its flame-retardant properties, block the spread of flames, and improve the safety of engine use.

[0031] Please see Figure 1-6 This utility model provides a technical solution:

[0032] A dustproof and waterproof sealed engine cover includes a first fixing plate 1 and a second fixing plate 2. The upper ends of the first fixing plate 1 and the upper ends of the second fixing plate 2 are both provided with through fixing holes 3. A sealing component 4 is fixedly connected between the first fixing plate 1 and the second fixing plate 2. A protective component 5 is sleeved on the upper end of the sealing component 4. Bolts 6 are threadedly connected to the four corners of the upper end of the protective component 5.

[0033] In this embodiment, the sealing assembly 4 includes a base plate 41, a sealing gasket 42 fixedly connected to the upper edge of the base plate 41, a sealing ring 43 fixedly sleeved inside the sealing gasket 42, and positioning sleeve rods 44 fixedly connected to the four corners of the upper end of the base plate 41. Each of the four positioning sleeve rods 44 has a first screw hole 45 at its upper end. The base plate 41 is fixedly connected between the first fixing plate 1 and the second fixing plate 2. The protective assembly 5 includes an aluminum alloy shell 51, an anti-deformation reinforcing rib 52 fixedly connected to the inner wall of the aluminum alloy shell 51, and a flame-retardant inner shell 53 fixedly connected to the inner wall of the anti-deformation reinforcing rib 52. 1. Positioning sleeve holes 55 are opened at the four corners of the lower end, and second screw holes 54 with internal and external penetration are opened at the four corners of the upper end of the aluminum alloy shell 51; the anti-deformation reinforcing ribs 52 are set as a grid structure formed by several horizontal bars and several vertical bars interwoven with each other; the sealing gasket 42 is located between the bottom plate 41 and the aluminum alloy shell 51, and the sealing ring 43 is sleeved in the flame-retardant inner shell 53; the four positioning sleeve rods 44 are respectively sleeved in the corresponding four positioning sleeve holes 55; the outer surfaces of the four bolts 6 are respectively threaded to the inner wall surface of the corresponding four second screw holes 54 and extend into the corresponding four first screw holes 45.

[0034] It should be noted that this utility model is a dustproof and waterproof sealed engine cover. During installation, align the positioning sleeve holes 55 at the four corners of the lower end of the aluminum alloy shell 51 of the protective component 5 with the positioning sleeve rods 44 at the four corners of the upper end of the base plate 41. Slowly and vertically lower the protective component 5, allowing the positioning sleeve rods 44 to smoothly insert into the positioning sleeve holes 55, thus completing the positional calibration of the protective component 5 and the sealing component 4, ensuring that the sealing component and the protective component correspond and fit together. Pick up the bolt 6, align its outer surface with the second screw holes 54 at the four corners of the upper end of the aluminum alloy shell 51, and rotate the bolt 6 clockwise to allow the bolt 6 to pass through the second screw holes 54 in sequence. 4. The positioning sleeve hole 55 is finally screwed into the first screw hole 45 of the positioning sleeve rod 44. As the bolt 6 is tightened, the protective component 5 gradually presses down on the sealing component 4. The sealing gasket 42 is compressed and undergoes elastic deformation, tightly fitting the lower end face of the aluminum alloy shell 51, preventing external dust and moisture from entering through the gap between the base plate 41 and the aluminum alloy shell 51. At the same time, the sealing ring 43 is compressed by the flame-retardant inner shell 53, filling the gap between the sealing gasket 42 and the flame-retardant inner shell 53, forming a second line of defense. Finally, the entire assembly is installed in the appropriate position on the engine through the fixing hole 3 and the fastener, completing the cover installation. In the engine compartment, the aluminum alloy shell 51, with its high strength and excellent corrosion resistance, directly resists external impacts from sand and gravel, scratches, and rainwater intrusion. Its smooth surface allows rainwater to quickly slide off, preventing water accumulation and erosion of the cover, thus constructing the first physical protective barrier for the engine compartment. The mesh-like anti-deformation reinforcing ribs 52 on the inner wall of the aluminum alloy shell 51, formed by interwoven horizontal and vertical bars, create a robust skeleton, greatly enhancing the structural strength of the shell. When the engine cover is subjected to external pressure or impact, the anti-deformation reinforcing ribs 52 quickly disperse stress, evenly transmitting the impact force to the entire aluminum alloy shell 51, effectively... To prevent local dents or deformations in the outer shell and ensure the structural integrity of the protective component 5, the flame-retardant inner shell 53 fits tightly against the inner wall of the anti-deformation reinforcing rib 52. When exposed to high temperatures or open flames, it effectively blocks the spread of flames to the engine compartment by utilizing its own flame-retardant properties, reducing the risk of fire. At the same time, the flame-retardant inner shell 53 and the sealing ring 43 fit tightly together, further compressing the sealing ring 43 and strengthening the internal sealing effect. Even in complex environments such as bumpy and humid conditions, it can prevent dust and moisture from seeping into the engine compartment from the internal gaps of the protective component 5, providing comprehensive protection for the engine compartment from external environmental interference and ensuring the normal and stable operation of the engine.
