Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an engine hood heat insulation pad assembly. Background Technology

[0002] The car hood is an important component in the car body structure used to cover the engine. The engine generates a lot of heat during operation. By installing a heat insulation pad inside the hood, the heat generated by the engine can be effectively prevented from being conducted into the surrounding environment, thereby improving the passenger's driving experience.

[0003] Existing engine heat shields are prone to bending and damage during installation and removal, resulting in high consumption and poor heat and sound insulation performance, leading to very low utilization. Therefore, this paper proposes an engine hood heat shield assembly that facilitates multi-layered heat and sound insulation, further blocking noise and heat generated during engine operation, preventing breakage during assembly, extending service life, and demonstrating strong practicality.

[0005] (2) The technical solution adopted by this utility model to solve its technical problem is an engine hood heat insulation pad assembly, including an upper cover plate, a clamping frame, a lower cover plate and a sound-absorbing layer. The upper cover plate has air holes at the top, a clamping frame at the bottom, and a lower cover plate at the bottom.

[0006] (3) An installation groove is provided in the lower cover plate, a sound insulation board core is placed in the installation groove, a heat insulation board is provided between the sound insulation board cores, and a sound absorption layer is adhered to the bottom of the lower cover plate.

[0012] (9) The beneficial effects of this utility model:

[0013] (10) The engine hood heat insulation pad assembly described in this utility model places the clamping frame on top of the sound insulation board core. By setting the clamping frame, the long bolt is rotated to press the sound insulation board core and the heat insulation board together, so that the two are fixed in the mounting groove to prevent slippage.

Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] To facilitate the installation of multiple layers of heat and sound insulation, further blocking the noise and heat generated during engine operation, and to prevent breakage during assembly, the service life can be extended, making it highly practical. Figure 1-4 As shown, the engine hood heat insulation pad assembly of this utility model includes an upper cover plate 1, a clamping frame 7, a lower cover plate 9 and a sound-absorbing layer 17. The upper cover plate 1 has an air hole 3 at the top, a clamping frame 7 at the bottom, and a lower cover plate 9 at the bottom.

[0023] An installation groove 10 is provided in the lower cover plate 9, and a sound insulation board core 12 is placed in the installation groove 10. A heat insulation board 13 is provided between the sound insulation board cores 12, and a sound absorption layer 17 is adhered to the bottom of the lower cover plate 9.

[0024] In use, the sound insulation core 12 and the heat insulation board 13 are placed in the mounting groove 10 in the lower cover plate 9 respectively. The clamping frame 7 is placed on top of the sound insulation core 12. By setting the clamping frame 7 and rotating the long bolt 8, the sound insulation core 12 and the heat insulation board 13 are clamped together, so that the two are fixed in the mounting groove 10 to prevent slippage.

[0025] During installation, when the upper cover plate 1 and the lower cover plate 9 are subjected to pressure, the elasticity of the shock-absorbing spring 14 squeezes the buffer block 15 close to both sides of the heat insulation plate 13, so that the internal pressure is distributed and the force is evenly distributed. This can reduce the impact force, increase the bending resistance of the upper cover plate 1 and the lower cover plate 9, avoid breakage during assembly, and extend the service life.

[0026] The silicone sleeve 6 has good elasticity and anti-slip properties, which increases the friction between the outer periphery of the locking post 5 and the locking groove 11, thereby reducing the phenomenon of slippage between the locking post 5 and the locking groove 11, and facilitating the stable connection of the upper cover plate 1 and the lower cover plate 9.

[0027] Then, pass the bolts through the mounting lugs 4 and install the upper cover plate 1 and the lower cover plate 9 onto the mounting bracket of the engine hood. This makes assembly convenient and the operation simple.

[0028] During vehicle movement, the design of the air vents 3 is to achieve better heat insulation. Usually, the upper cover plate 1 and the lower cover plate 9 are made of PVC material. These air vents 3 can effectively block the heat generated by sunlight. The inner layer of the air vents 3 is fitted with a dustproof mesh by bolts, which can filter the dust carried in the airflow.

[0029] Then, a special polyvinyl alcohol adhesive is used to bond the lower cover plate 9, the sound-absorbing layer 17, and the engine hood together, which can effectively isolate the noise generated when the engine is running.

[0030] For ease of assembly, as exemplified, such as Figure 1 , Figure 2 , Figure 3As shown, the present invention also includes the upper cover plate 1 and the lower cover plate 9 being connected to the mounting ears 4 by bolts around their respective perimeters.

[0031] In use, by setting the mounting ears 4, the upper cover plate 1 and the lower cover plate 9 are installed on the mounting bracket of the engine hood, which is convenient for assembly and simple to operate.

[0032] For example, such as Figure 1 , Figure 3 As shown, the present invention also includes slots 11 formed on the periphery of the mounting groove 10 at the top of the lower cover plate 9.

[0033] For example, such as Figure 1 , Figure 2 , Figure 3 As shown, this utility model also includes, the bottom four sides of the upper cover plate 1 are all bolted with locking posts 5, the outer periphery of the locking posts 5 is fitted with a silicone sleeve 6 that fits with the locking groove 11, and the top of the upper cover plate 1 is tightened with bolts 2 through the reserved openings around the locking posts 5.

[0034] When in use, the silicone sleeve 6 has good elasticity and anti-slip properties, which increases the friction between the outer periphery of the locking post 5 and the locking groove 11, thereby reducing the phenomenon of slippage between the locking post 5 and the locking groove 11, and facilitating a stable connection between the upper cover plate 1 and the lower cover plate 9.

[0035] For example, such as Figure 2 , Figure 3 , Figure 4 As shown, this utility model also includes limiting holes 16 respectively opened on the surfaces of the sound insulation core 12 and the heat insulation plate 13, and long bolts 8 through the reserved opening on the top surface of the clamping frame 7 are threadedly connected to the sound insulation core 12 and the heat insulation plate 13 respectively.

[0036] For example, such as Figure 3 , Figure 4 As shown, the present invention also includes shock-absorbing springs 14 installed at the top and bottom of the inner cavity of the heat insulation plate 13 by bolts, and one end of the shock-absorbing spring 14 is connected to the buffer block 15 by screws.

[0037] During use, by setting up the clamping frame 7 and rotating the long bolt 8, the sound insulation core 12 and the heat insulation plate 13 are pressed and fixed in the mounting groove 10 to prevent slippage. When the car is driving, there will be a bumpy phenomenon. When the upper cover plate 1 and the lower cover plate 9 are under pressure, the elasticity of the shock-absorbing spring 14 squeezes the buffer block 15 close to both sides of the heat insulation plate 13, so that the internal pressure is distributed and the force is evenly distributed. This can reduce the impact force, increase the bending resistance of the upper cover plate 1 and the lower cover plate 9, and prevent breakage during installation.

[0038] In use, the sound insulation core 12 and the heat insulation board 13 are placed in the mounting groove 10 in the lower cover plate 9, and the clamping frame 7 is placed on top of the sound insulation core 12. By setting the clamping frame 7 and rotating the long bolt 8, the sound insulation core 12 and the heat insulation board 13 are clamped together, so that the two are fixed in the mounting groove 10 and prevented from sliding.

[0039] During installation, when the upper cover plate 1 and the lower cover plate 9 are subjected to pressure, the elasticity of the shock-absorbing spring 14 squeezes the buffer block 15 close to both sides of the heat insulation plate 13, so that the internal pressure is distributed and the force is evenly distributed. This can reduce the impact force, increase the bending resistance of the upper cover plate 1 and the lower cover plate 9, avoid breakage during assembly, and extend the service life.

[0040] The silicone sleeve 6 has good elasticity and anti-slip properties, which increases the friction between the outer periphery of the locking post 5 and the locking groove 11, thereby reducing the phenomenon of slippage between the locking post 5 and the locking groove 11, and facilitating the stable connection of the upper cover plate 1 and the lower cover plate 9.

[0041] Then, pass the bolts through the mounting lugs 4 and install the upper cover plate 1 and the lower cover plate 9 onto the mounting bracket of the engine hood. This makes assembly convenient and the operation simple.

[0042] During vehicle movement, the design of the air vents 3 is to achieve better heat insulation. Usually, the upper cover plate 1 and the lower cover plate 9 are made of PVC material. These air vents 3 can effectively block the heat generated by sunlight. The inner layer of the air vents 3 is fitted with a dustproof mesh by bolts, which can filter the dust carried in the airflow.

[0043] Then, a special polyvinyl alcohol adhesive is used to bond the lower cover plate 9, the sound-absorbing layer 17, and the engine hood together, which can effectively isolate the noise generated when the engine is running.
