Description

Technical Field

[0001] This utility model relates to the field of automotive engine technology, specifically an engine intake pipe ice-breaking device. Background Technology

[0002] In 2024, domestic passenger vehicle sales reached 22.608 million units, with traditional gasoline-powered vehicles accounting for over 59.1% of sales. This was especially true in the cold Northeast region, where gasoline-powered vehicles still dominated. Gasoline-powered vehicles are driven by engine combustion, requiring the intake manifold to deliver clean, dry, sufficient, and stable air to meet the engine's needs and prevent impurities and large dust particles from entering the combustion chamber and causing abnormal engine wear. In cold regions, there is a risk of icing in the engine's intake manifold. The main reason for icing in a car engine's intake manifold is that moisture in the air condenses on the cold components of the cooling system in low-temperature environments, forming an ice layer that blocks the intake manifold, affecting the normal operation of the engine and thus impacting vehicle performance and driving safety.

[0003] The specific effects of intake manifold icing on the engine include: 1. Reduced engine power: Icing in the intake manifold reduces the area of ​​the intake passage, resulting in a decrease in the airflow into the engine, thereby reducing engine power.

[0004] 2. Increased engine vibration: Asymmetrical icing and uneven shedding of ice layers can disrupt the dynamic balance of the rotor, leading to increased engine vibration.

[0005] 3. Increased engine fuel consumption: Icing can disrupt the aerodynamic shape, increase flight drag, and lead to increased fuel consumption.

[0006] 4. Engine bearing damage: Falling ice may hit the blades, causing damage to components such as the compressor.

[0007] The current engine intake lacks the necessary structure to prevent ice from entering the engine, which is not conducive to ensuring the engine can be used on icy roads. Utility Model Content

[0008] In order to solve the above problems, the purpose of this utility model is to provide an engine intake pipe ice-breaking device.

[0009] To achieve the above objectives, the technical solution of this utility model is as follows: an engine intake pipe ice-breaking device, comprising an outer support ring and an inner ring supported in the center of the outer support ring, and a middle ring is also supported between the outer support ring and the inner ring, and the center lines of the outer support ring, the inner ring and the middle ring overlap, and multiple plate-shaped support structures penetrating the middle ring are provided around the outer periphery of the inner ring, and the plane of the plate-shaped support structure is parallel to the center lines of the outer support ring, the inner ring and the inner ring.

[0010] Furthermore, the lengths of the outer support ring, the middle ring, and the middle ring decrease sequentially.

[0011] Furthermore, the length of the plate-shaped support structure between the inner ring and the middle ring gradually widens from the inside to the outside, and the inner end length of the plate-shaped support structure is the same as the length of the inner ring.

[0012] Furthermore, the length of the plate-like support structure between the middle ring and the outer support ring is the same as the length of the middle ring.

[0013] Furthermore, the outer edge of the air intake end of the outer support ring is an outwardly inclined annular slope structure.

[0014] Furthermore, the inner ring, the middle ring, and the air intake end edge of the plate-shaped support structure are outwardly convex arc-shaped structures.

[0015] Furthermore, the outer support ring, inner ring, middle ring, and plate-shaped support structure are integrally injection molded using PA66GF30 injection molding material.

[0016] Furthermore, there are six plate-shaped support structures, which are evenly distributed between the outer support ring, the inner ring, and the middle ring.

[0017] With the above settings, this utility model designs an ice-breaking structure device inside the intake pipe, targeting the intake pipe routing. The strength of the ice-breaking structure is analyzed using CAE analysis to prevent damage to the device under high pressure and high airflow, which could then enter the engine. The blades of the ice-breaking structure are designed according to the engine's required intake volume, and pressure drop analysis is performed using CAE software. This utility model's structure ensures that the flow resistance generated by the ice-breaking structure can meet the engine's intake volume requirements. Moreover, this structural design achieves natural ice breaking without additional energy consumption, resulting in environmental protection and low cost. Attached Figure Description

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0020] like Figure 1-2As shown, an engine intake pipe ice-breaking device includes an outer support ring 1 and an inner ring 2 supported at the center of the outer support ring 1. An intermediate ring 3 is also supported between the outer support ring 1 and the inner ring 2. The center lines of the outer support ring 1, the inner ring 2 and the intermediate ring 3 overlap. Multiple plate-shaped support structures 4 are provided around the outer periphery of the inner ring 2, penetrating the intermediate ring 3. The plane of the plate-shaped support structure 4 is parallel to the center lines of the outer support ring 1, the inner ring 2 and the inner ring 2.

[0021] Specifically: the lengths of the outer support ring 1, the middle ring 3 and the middle ring 3 decrease sequentially; the length of the plate-shaped support structure 4 between the inner ring 2 and the middle ring 3 gradually increases from the inside to the outside, and the length of the inner end of the plate-shaped support structure 4 is the same as the length of the inner ring 2; the length of the plate-shaped support structure 4 between the middle ring 3 and the outer support ring 1 is the same as the length of the middle ring 3; the outer edge of the air inlet end of the outer support ring 1 is an outwardly inclined annular slope structure 5; the edges of the air inlet ends of the inner ring 2, the middle ring 3 and the plate-shaped support structure 4 are outwardly convex arc surface structures 6; the outer support ring 1, the inner ring 2, the middle ring 3 and the plate-shaped support structure 4 are integrally injection molded using PA66GF30 injection molding material; there are six plate-shaped support structures 4 in total, and they are evenly arranged between the outer support ring 1, the inner ring 2 and the middle ring 3.

[0022] The working principle of this utility model includes the following specific design steps: 1. Based on the pressure drop requirements input by the customer, use CAE analysis software to calculate the pressure drop value of the pipeline without the addition of an ice-breaking structure; 2. The ice-breaking structure was designed using CATIA 3D software. The six supports and the central ring effectively prevent ice from entering the engine, ensuring product strength while minimizing pressure drop. PA66+GF30 injection molding material was used to reduce weight while maintaining strength. 3. CAE analysis was used to assess the strength of the newly designed icebreaking structure to meet customer requirements; 4. Install the newly designed ice-breaking structure inside the pipeline and use CAE software to calculate the pipeline pressure drop value with the added ice-breaking structure. 5. Design and assemble the ice-breaking structure inside the pipeline; 6. Real vehicle testing.

Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
