[0001] This application relates to the field of vehicle power, and more particularly to an engine intake chamber housing, an engine assembly, and a vehicle. Background Technology

[0002] The car's air intake system is an important component of the engine, mainly consisting of an air filter, intake manifold, and exhaust manifold. Its main function is to provide the engine with clean, dry, and sufficient fresh air to meet the needs of the combustion process.

[0003] Currently, air intake systems are mainly designed based on their performance. However, due to the large number of components and the large space occupied by the air intake system in the front nacelle, the overall coordination of the nacelle is poor. Utility Model Content

[0004] This application provides an engine intake chamber housing, which aims to at least solve the problem that the intake system in the prior art contains many components and occupies a large space in the front engine compartment, resulting in poor overall coordination of the engine compartment.

[0005] In a first aspect, embodiments of this application provide an engine intake chamber housing, mounted above the engine, comprising:

[0006] The housing body has an internal air filter housing for installing an air filter. An oil filler port and an oil dipstick port are provided on the side of the housing body away from the engine. The oil filler port and the oil dipstick port are located on both sides of the air filter housing. The oil filler port and the oil dipstick port are both connected to the inside of the engine's oil pan. The air filter housing, the oil filler port, and the oil dipstick port are independent of each other.

[0007] Optionally, the air filter includes an air filter outlet duct, the air filter housing includes an inlet chamber and an outlet chamber that are interconnected, the inlet chamber is provided with an air inlet, the outlet chamber is connected to the inlet end of the air filter outlet duct, and the outlet end of the air filter outlet duct is connected to the engine.

[0008] Optionally, the housing body is further provided with a resonant cavity, which is located on one side of the air outlet chamber and is connected to the end of the air filter outlet pipe away from the air outlet chamber.

[0009] Optionally, a tubular gap exists between the outer wall of the resonant cavity and the outer wall of the exhaust cavity, and the oil filler port is located at the end of the tubular gap away from the engine.

[0010] Optionally, the housing body includes an upper housing and a lower housing, the upper housing being located on the side of the lower housing away from the engine, and the oil filler port and the oil dipstick port being disposed on the upper housing.

Detailed Implementation

[0024] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0025] Currently, air intake systems are primarily designed based on their performance. However, due to the large number of components and the significant space they occupy in the engine compartment, the overall aesthetics and coordination of the engine compartment are poor. To address these issues, this application provides an engine intake chamber housing.

[0026] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0027] In a first aspect, this utility model discloses an engine intake chamber housing, referring to... Figure 1 and Figure 2 As shown, the housing body 1 includes an internal air filter housing 11 for installing an air filter. An oil filler port 12 and an oil dipstick port 13 are located on the side of the housing body 1 furthest from the engine. The oil filler port 12 and the oil dipstick port 13 are located on opposite sides of the air filter housing 11 and are both connected to the engine's oil pan. The air filter housing 11, the oil filler port 12, and the oil dipstick port 13 are independent of each other.

[0028] When installing the engine intake chamber housing, the housing body 1 is positioned above the engine, acting as an engine cover to shield the engine. Since the air filter housing 11 is located inside the housing body 1, it also covers the engine intake chamber housing itself. Furthermore, the oil filler neck 12 and oil dipstick neck 13 are located on the side of the housing body 1 furthest from the engine, allowing operators to add or check the oil level without moving surrounding engine components. By acting as an engine cover while simultaneously shielding its own chamber, the housing body 1 achieves component integration, resulting in a more compact engine intake system layout, higher space utilization, and improved functionality. This addresses the issue of cluttered components in the engine compartment, providing more space for the installation and arrangement of other vehicle components.

[0029] The oil filler cap is a key structure in the engine lubrication system used for adding engine oil. It is usually located on the top or side of the engine and connected to the oil pan. Its structure mainly consists of a circular or elliptical opening with a smooth inner wall to facilitate the smooth flow of engine oil into the oil pan. The main function of the oil filler cap is to add engine oil to the engine oil pan, ensuring the normal operation of the engine lubrication system.

[0030] The oil dipstick opening is an important structure in the engine lubrication system used to check the oil level. It is usually located on the upper or side of the engine and connected to the oil pan. Its structure mainly consists of a narrow opening for inserting the oil dipstick. The inner wall of the opening is usually designed to be smooth so that the dipstick can be easily inserted and removed. The main function of the oil dipstick opening is to provide operators with a convenient channel to check the oil level. By inserting the dipstick into the opening and extending it into the oil pan, operators can visually observe whether the oil level is within the normal range.

[0031] Air filters are a key component of the engine intake system. Their main structure includes a housing and a filter element. The main function of an air filter is to filter the air entering the engine, preventing dust and impurities from entering the engine cylinders, thereby reducing wear on engine parts and extending the engine's service life.

[0032] In a preferred embodiment, refer to Figure 1 and Figure 3 The air filter includes an air filter outlet pipe 2. The air filter housing 11 includes an intake chamber 111 and an outlet chamber 112 that are connected to each other. The intake chamber 111 is provided with an air inlet. The outlet chamber 112 is connected to the inlet end of the air filter outlet pipe 2. The outlet end of the air filter outlet pipe 2 is connected to the engine.

[0033] In this embodiment, the filter element of the air filter is located in the intake chamber 111. When the engine is running, air enters the intake chamber 111 through the intake port. The filter element in the intake chamber 111 removes dust, sand particles and other impurities from the air, thus filtering the air. The filtered air then enters the exhaust chamber 112, which is connected to the inlet end of the air filter exhaust pipe 2. The air passes through the exhaust chamber 112 and then enters the air filter exhaust pipe 2. The presence of the exhaust chamber 112 provides a buffer space for the air, slowing down the airflow speed and thus reducing the pressure on the air filter exhaust pipe 2 when the air enters it to a certain extent.

[0034] In a preferred embodiment, refer to Figure 1 and Figure 3 The housing body 1 is also provided with a resonant cavity 14, which is located on one side of the air outlet chamber 112. The resonant cavity 14 is connected to the end of the air filter outlet pipe 2 away from the air outlet chamber 112.

[0035] In this embodiment, the two ends of the air filter outlet pipe 2 are connected to the outlet chamber 112 and the resonant cavity 14, respectively. The outlet end of the air filter outlet pipe 2 is located in the middle of the air filter outlet pipe 2. When air passes through the air filter outlet pipe 2, the eddies and pressure fluctuations generated by the air flow will cause a certain noise. When the sound wave enters the resonant cavity 14 along the air filter outlet pipe 2, the air in the cavity will resonate at a certain frequency. When the frequency of the sound wave entering the resonant cavity 14 matches the resonant frequency of the resonant cavity 14, the energy of the sound wave is absorbed by the air in the resonant cavity 14 and converted into other forms of energy such as heat energy, thereby reducing the noise caused by the air flow. In addition, the connection design between the resonant cavity 14 and the air filter outlet pipe 2 allows the pressure fluctuations generated when the air passes through the air filter outlet pipe 2 to be partially absorbed and balanced by the resonant cavity 14, so that the pressure fluctuations are dispersed and buffered in the cavity, further reducing the pressure impact on the air filter outlet pipe 2.

[0036] In a preferred embodiment, refer to Figure 1 and Figure 3 There is a tubular gap 15 between the outer wall of the resonant cavity 14 and the outer wall of the exhaust chamber 112, and the oil filler port 12 is located at the end of the tubular gap 15 away from the engine.

[0037] The oil filler port 12 is located at the end of the tubular gap 15 away from the engine, so that the operator does not need to perform complicated operations around the engine when adding oil to the engine oil pan. At the same time, the oil filler port 12 is set in the gap between the outer wall of the resonant cavity 14 and the outer wall of the exhaust chamber 112, which realizes the integration and compactness of the housing body 1 design and improves the space utilization of the housing body 1.

[0038] In a preferred embodiment, refer to Figure 2 and Figure 3 The housing body 1 includes an upper housing 16 and a lower housing 17. The upper housing 16 is located on the side of the lower housing 17 away from the engine. The oil filler port 12 and the oil dipstick port 13 are located on the upper housing 16.

[0039] In this embodiment, the upper housing 16 and the lower housing 17 are snapped together. The upper housing 16 is larger than the lower housing 17, and it covers the lower housing 17. When inspecting the interior of the air filter housing 11, only the upper housing 16 needs to be disassembled to observe the interior. After the upper housing 16 and the lower housing 17 are snapped together, the upper housing 16 covers its own chamber, improving the problem of cluttered parts in the car's engine compartment. In addition, since the oil filler port 12 and the oil dipstick port 13 are located on the upper housing 16, it is convenient for operators to add oil or check the oil level in the engine oil pan. At the same time, the upper housing 16 covers the connection between the air filter outlet pipe 2, the air filter housing 11, and the engine, reducing the accumulation of dust and other impurities in these areas, thereby ensuring the cleanliness of the air flowing through the air filter outlet pipe 2 to a certain extent.

[0040] In a preferred embodiment, refer to Figure 1 and Figure 2 The oil filler neck 12 is equipped with a filler neck cap, and the oil dipstick neck 13 is equipped with a dipstick neck cap. After the engine intake chamber housing is installed on top of the engine, engine oil is added to the oil pan through the oil dipstick neck 13. Under normal conditions, the filler neck 12 and oil dipstick neck 13 are closed by the filler neck cap and dipstick neck cap, respectively. The design of the filler neck cap and dipstick neck cap effectively prevents dust, impurities, and moisture from entering the oil pan. If these contaminants enter the engine oil, they may cause oil deterioration and affect the engine's lubrication performance. By maintaining the cleanliness of the engine oil, the filler neck cap and dipstick neck cap extend the service life of the engine oil and reduce the risk of engine failure due to oil contamination.

[0041] In a preferred embodiment, refer to Figure 1 and Figure 4 The engine intake chamber housing also includes an intake pipe 3, the output end of which is connected to the air filter housing 11. The intake pipe 3 is located between the upper housing 16 and the engine.

[0042] In this embodiment, the size of the intake pipe 3 gradually increases in the direction away from the air filter housing 11. When the engine is running, air enters the intake chamber 111 through the intake pipe 3. The gradually increasing size of the intake pipe 3 can effectively reduce the resistance of air flow, allowing air to enter the engine more smoothly. In addition, the intake pipe 3 is located between the upper housing 16 and the engine, so that the upper housing 16 covers part of the structure of the intake pipe 3, further improving the problem of cluttered parts in the car's engine compartment.

[0043] In a preferred embodiment, refer to Figure 1 and Figure 4 The engine intake chamber housing also includes a heat insulation pad 4, which is located on the side of the housing body 1 closest to the engine. During engine operation, a large amount of heat is generated. The heat insulation pad 4 blocks some of this heat, reducing heat transfer to the housing body 1 and protecting it from high temperatures, thus ensuring the air filter inside the housing body 1 operates within its normal temperature range. Simultaneously, when subjected to external forces from the engine, the heat insulation pad 4 absorbs and buffers vibration energy, reducing vibration transmission.

[0044] In a preferred embodiment, refer to Figure 1 and Figure 4 The engine intake chamber housing also includes a rubber vibration damping bushing 5, which is located between the housing body 1 and the engine. The rubber vibration damping bushing 5 is made of high-performance rubber materials with good elasticity and damping properties. The elasticity of rubber allows it to deform under external force, thereby absorbing and buffering vibration energy. Simultaneously, the damping properties of rubber can convert vibration energy into heat energy, further reducing the vibration energy received from the engine and reducing vibration transmission.

[0045] In a preferred embodiment, refer to Figure 2 and Figure 3 The surface of the housing body 1 is provided with reinforcing ribs. During engine operation, the housing body 1 is subjected to various forces such as engine vibration and air pressure. These forces can cause local stress concentration on the housing body 1. The design of the reinforcing ribs can disperse these stresses to a wider area, thereby reducing local stress concentration and improving the overall compressive strength of the housing body 1.

[0046] In this embodiment, reinforcing ribs are provided on the inner surfaces of the upper housing 16 and the lower housing 17. When the housing body 1 is subjected to various forces such as engine vibration and air pressure, the reinforcing ribs on the inner surfaces of the upper housing 16 and the lower housing 17 disperse these forces and reduce local stress concentration. At the same time, since the reinforcing ribs are provided on the inner surfaces of the upper housing 16 and the lower housing 17, the amount of external dust particles adhering to the surface of the reinforcing ribs is reduced, thereby improving the overall compressive strength of the housing body 1 and enhancing the cleanliness of the engine intake chamber housing.

[0047] In another embodiment of this application, the oil dipstick opening 13 of the engine intake chamber housing can also be located at the end of the tubular gap 15 away from the engine. In this case, the oil filler port 12 and the oil dipstick opening 13 are located on the same side of the air filter housing 11.

[0048] By utilizing the gap between the outer wall of the resonant cavity 14 and the outer wall of the air outlet chamber 112, an oil filler port 12 and an oil dipstick port 13 are provided, further realizing the integration and compactness of the housing body 1 design and improving the space utilization of the housing body 1. At the same time, since the oil filler port 12 and the oil dipstick port 13 are located on the same side of the air filter housing 11, more space is provided for the air filter housing 11, allowing the filter element volume and area within the air filter housing 11 to be further increased. The increased filtration area can capture more dust, sand particles, and other impurities, thereby improving the filtration efficiency of the air filter.

[0049] In this embodiment, when installing the engine intake chamber housing, the housing body 1 is positioned above the engine, acting as an engine cover to shield the engine. Since the air filter housing 11 is located inside the housing body 1, it also covers the engine intake chamber housing itself. Furthermore, the oil filler neck 12 and oil dipstick neck 13 are located on the side of the housing body 1 furthest from the engine, eliminating the need for operators to move surrounding engine components when adding or checking oil levels. By acting as an engine cover while simultaneously shielding its own chamber, the housing body 1 achieves component integration, resulting in a more compact engine intake system layout, higher space utilization, and improved functionality. This addresses the issue of cluttered components in the vehicle's engine compartment, providing more space for the installation and arrangement of other vehicle components.
