Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a sealing and decorative component for an automotive engine compartment. Background Technology

[0002] To make the engine compartment look neat and clean, improve NVH performance, and meet consumer requirements, some domestic car brands have developed front engine compartment trim panels. However, to meet requirements such as visibility of coolant and other filler lines, these trim panels are generally designed with detachable modular structures in the corresponding locations.

[0003] A document with publication number CN221718467U discloses a novel automotive front engine compartment trim panel with a viewing window function. The panel includes a trim panel body, a maintenance cover, and protective components. Several mounting holes ensure the stability of the trim panel body's installation in the automotive front engine compartment. Sealing strips at the bottom and top of the trim panel body enhance the seal between the trim panel body and the automotive front engine compartment, preventing damage to internal engine components. Furthermore, the protective panel, sound-absorbing layer, and several ventilation holes reduce noise from the automotive engine while preventing insufficient engine cooling. This technical solution addresses the problem in existing technologies where the automotive engine is not further decorated, and the engine generates noise during operation, affecting the driving experience.

[0004] However, the protective plate of the device is fitted to the engine hood at the bottom. Although ventilation holes are opened on the protective plate, the air flow rate of the ventilation holes is low, which reduces the air exchange speed on the top of the engine and thus leads to poor heat dissipation.

[0005] Therefore, it is necessary to provide an automotive engine compartment sealing trim to solve the above-mentioned technical problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the existing technology, this utility model provides an automotive engine compartment sealing decoration part that can help the engine dissipate heat.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] Preferably, shock-absorbing cotton is installed at the bottom of the cover.

[0010] Preferably, a reducer is installed between the exhaust pipe and the intake shroud.

[0011] Preferably, the bottom of the decorative panel body has an embedding groove.

[0012] Preferably, the decorative panel body has mounting holes.

[0013] Preferably, the air intake cover is provided with a first connection hole, and the cover is provided with a second connection hole.

[0014] Preferably, sound-absorbing cotton is installed inside the housing.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) By setting up a decorative panel body, an air intake cover, a cover, an exhaust pipe, and a connecting pipe, this utility model can conveniently guide high-speed airflow to extract hot air above the engine and discharge the hot air to the top of the decorative panel body, which is beneficial to the heat dissipation of the engine and prevents the engine from experiencing high temperature failure.

[0017] (2) By installing shock-absorbing cotton at the bottom of the cover, this utility model can help reduce the vibration of the decorative panel body, reduce noise, and make the connection between the decorative panel body and the engine compartment more stable.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0028] Example 1:

[0029] like Figure 1-5As shown, this utility model provides a sealing and decorative component for an automotive engine compartment, comprising: a decorative panel body 1, which is sealed to the engine compartment on all four sides. Its structure can adopt existing sealing structure designs, which will not be elaborated here. A heat dissipation mechanism is provided on the decorative panel body 1, including multiple air intake hoods 2 located on the front side of the decorative panel body 1. The air intake hoods 2 are installed behind the front air intake grille of the automotive engine compartment. When the car is moving, front air enters the air intake hoods 2. A cover 3 is installed at the bottom of the decorative panel body 1 (located above the engine). The bottom edge of the cover 3 conforms to the engine hood design, and air intakes are provided on the sides of the cover 3. Multiple exhaust pipes 4 are installed on the top of the cover 3. Each exhaust pipe 4 has a sufficiently large diameter outlet 5 located above the decorative panel body 1. The exhaust pipes 4 communicate with the air intake hoods 2. Multiple connecting pipes 6 are installed obliquely between the exhaust pipes 4 and the cover 3, allowing air to pass through the connecting pipes 6. Air below the cover 3 can be discharged into the exhaust pipe 4. It is worth noting that the inner diameter of the connecting pipe 6 is much smaller than the inner diameter of the exhaust pipe 4. When the car is moving forward, the compressed air in front enters the air intake cover 2 through the air intake grille. The airflow is compressed again in the air intake cover 2. The high-speed airflow passes through the exhaust pipe 4 and is discharged from the air outlet 5 to the space above the decorative panel body 1. Finally, the airflow is discharged from the gap between the hood and the engine compartment. At the same time, according to the Bernoulli and Venturi tube principles, the high-speed airflow flows in the exhaust pipe 4, which creates a negative pressure at the connection between the connecting pipe 6 and the exhaust pipe 4. The air in the connecting pipe 6 is drawn into the exhaust pipe 4, which in turn causes the air in the cover 3 connected to the connecting pipe 6 to be continuously drawn into the exhaust pipe 4. Fresh air from the outside enters the cover 3 through the side air intake, which allows the hot air at the top of the engine to dissipate quickly, which is beneficial for engine cooling and prevents the engine from overheating.

[0030] By setting up the decorative panel body 1, air intake cover 2, cover 3, exhaust pipe 4, and connecting pipe 6, it is possible to conveniently guide high-speed airflow to draw hot air above the engine and exhaust the hot air to the top of the decorative panel body 1, which is beneficial to the heat dissipation of the engine and prevents the engine from overheating.

[0031] Example 2:

[0032] Shock-absorbing cotton is installed between the bottom edge of the cover 3 and the engine hood. When the engine is running, the vibration generated is damped by the shock-absorbing cotton, which reduces the vibration of the cover 3, thereby reducing the vibration of the decorative panel body 1. This ensures that the connecting screws between the decorative panel body 1 and the engine compartment will not loosen or even fall off.

[0033] By installing damping cotton at the bottom of the cover 3, it is possible to reduce the vibration of the decorative panel body 1, reduce noise, and make the connection between the decorative panel body 1 and the engine compartment more stable.

[0034] Example 3:

[0035] like Figure 1-5 As shown, a reducer pipe 7 is installed between the exhaust pipe 4 and the intake shroud 2. In use, compressed air in the intake shroud 4 enters the exhaust pipe 4 through the reducer pipe 7. Since the diameter of the end of the reducer pipe 7 connected to the intake shroud 2 is larger than that of the other end, the air velocity will be further increased when passing through the reducer pipe 7, thereby increasing the air velocity in the exhaust pipe 4, which in turn accelerates the air exchange speed at the top of the engine and speeds up the heat dissipation.

[0036] By installing a reducer 7 between the exhaust pipe 4 and the intake shroud 2, the airflow velocity entering the exhaust pipe 4 can be further increased, which is beneficial to improving the heat dissipation speed.

[0037] Example 4:

[0038] like Figure 4 As shown, an embedding groove 9 is provided at the bottom of the decorative panel body 1, and the top of the exhaust pipe 4 is embedded in the embedding groove 9, which makes it easier to reduce the space occupied by the exhaust pipe 4 and facilitates installation in the engine compartment where space is limited.

[0039] By opening an embedding groove 9 at the bottom of the decorative panel body 1, part of the exhaust pipe 4 can be easily embedded and installed at the bottom of the decorative panel body 1, thereby reducing the space occupied by the exhaust pipe 4 and making it easier to install the exhaust pipe 4 in the engine compartment.

[0040] Example 5:

[0041] like Figure 4 As shown, a mounting hole 10 is provided on the decorative panel body 1, and the air outlet 5 passes through the mounting hole 10.

[0042] By opening mounting holes 10 on the decorative panel body 1, it is easy for the exhaust pipe 4 to pass through the decorative panel body 1.

[0043] Example 6:

[0044] like Figure 3 and Figure 5 As shown, a first connecting hole 11 is provided on the air intake hood 2, and a second connecting hole 12 is provided on the cover 3. During installation, screws are used to pass through the first connecting hole 11 and the second connecting hole 12 to connect the air intake hood 2 to the cabin frame and the cover 3 to the decorative panel body 1.

[0045] By providing the first connecting hole 11 and the second connecting hole 12, the installation of the air intake cover 2 and the cover 3 can be facilitated.

[0046] In Example 7, sound-absorbing cotton is installed inside the housing 3, avoiding the location of the connecting pipe 6. The sound-absorbing cotton reduces the noise of the housing 3, which helps to reduce engine noise pollution.

[0047] By installing sound-absorbing cotton inside the housing 3, the outward transmission of noise can be reduced, achieving the effect of noise reduction.

[0048] Working principle: When the car is moving forward, the compressed air in front enters the air intake hood 2 through the air intake grille. The airflow is compressed again in the air intake hood 2. The high-speed airflow passes through the exhaust pipe 4 and is discharged from the air outlet 5 to the space above the decorative panel body 1. Finally, the airflow is discharged from the gap between the hood and the engine compartment. At the same time, according to the Bernoulli and Venturi tube principles, the high-speed airflow flows in the exhaust pipe 4, the temperature decreases, and a negative pressure is created at the connection between the connecting pipe 6 and the exhaust pipe 4. The air in the connecting pipe 6 is drawn into the exhaust pipe 4, which in turn draws the air in the cover 3 connected to the connecting pipe 6 into the exhaust pipe 4. Fresh air from the outside enters the cover 3 through the side air intake, which allows the hot air on the top of the engine to dissipate as quickly as possible, which is beneficial for engine heat dissipation and prevents the engine from overheating.
