Description

Technical Field

[0001] The utility model relates to the technical field of wind shields, and more specifically, to a lightweight and flexible wind shield for a diesel engine. Background Art

[0002] As emission and fuel consumption regulations become increasingly stringent, diesel engine power and load continue to increase, and the requirements for the engine's cooling system capacity are becoming increasingly higher. Generally, the engine is connected to the vehicle's cooling package through a fan guard. Figure 1-2 As shown, existing windshields typically consist of a fixing bracket 1, a metal ring 2, and a rubber ring 3. The rubber ring 3 is directly riveted into the axial U-shaped structure of the metal ring 2. During vehicle operation, the metal ring and the rubber ring experience relative displacement, causing the metal windshield to wear the rubber ring. This can lead to damage to the rubber ring after prolonged use, affecting engine cooling.

[0003] Therefore, it is urgent to design a lightweight and flexible wind shield for diesel engines to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a lightweight and flexible wind shield for a diesel engine in response to the above-mentioned deficiencies in the prior art, thereby reducing the relative displacement problem caused by the different vibration amplitudes of the engine and the cooling pack, and lowering the risk of the wind shield breaking.

[0005] The technical solution of the present utility model is as follows: a lightweight flexible wind shield ring for a diesel engine, comprising a fixed bracket and a rubber ring, and also comprising a plastic wind ring, wherein the fixed bracket is detachably connected to the plastic wind ring, and the outer wall of the plastic wind ring is provided with a plurality of reinforcing ribs, a first annular groove is radially opened on the outer wall of one end of the plastic wind ring away from the fixed bracket, and a first annular insert is formed on one side of the first annular groove, a second annular groove is radially opened on the inner wall of one end of the rubber ring, and a second annular insert is formed on one side of the second annular groove, the first annular insert is inserted into the second annular groove, and the second annular insert is inserted into the first annular groove.

[0006] As a further improvement, the plurality of reinforcing ribs are evenly distributed on the outer wall of the plastic air ring, and the plurality of reinforcing ribs and the plastic air ring are an integrally formed structure using a plastic material.

[0007] Furthermore, there is interference fit between the first annular insert and the second annular groove, and between the second annular insert and the first annular groove.

[0008] Furthermore, the fixing bracket and the plastic air ring are connected by a plurality of bolts.

[0009] Furthermore, the inner wall of the rubber ring is an inclined surface whose inner diameter gradually increases along the side away from the plastic wind ring; the inner wall of the plastic wind is an inclined surface whose inner diameter gradually increases along the side away from the rubber ring.

[0010] Furthermore, the wall thickness of the rubber ring gradually decreases along the side away from the plastic air ring.

[0011] Beneficial effects

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The flexible wind shield of the present invention changes the metal ring into a plastic wind shield and adds reinforcing ribs, making the entire wind shield lighter while ensuring strength. The flexible wind shield made of rubber is connected to the cooling pack of the entire vehicle, which can reduce the relative displacement problem caused by the different vibration amplitudes of the engine and the cooling pack, and reduce the risk of wind shield breakage.

[0014] 2. The flexible wind protection ring of the utility model adopts two radial annular grooves and two inserts to connect the plastic wind ring and the rubber ring. The axial U-shaped structure directly riveted to the metal ring is changed to a radial double U-shaped connection structure, which increases the anti-pullout ability of the rubber ring, prevents the rubber ring from being worn, and further extends the service life.

[0020] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0021] See Figure 3-4The utility model provides a lightweight flexible wind shield for a diesel engine, comprising a fixing bracket 1 and a rubber ring 3, and also comprising a plastic wind ring 4. The plastic wind ring 4 is made of plastic or rubber material, and the fixing bracket 1 is detachably connected to the plastic wind ring 4, which is convenient for disassembly and maintenance. A plurality of reinforcing ribs 5 are provided on the outer wall of the plastic wind ring 4 to ensure the structural strength of the plastic wind ring 4. A first annular groove 6 is radially opened on the outer wall of the end of the plastic wind ring 4 away from the fixing bracket 1, and a first annular insert 7 is formed on one side of the first annular groove 6. A second annular groove 8 is radially opened on the inner wall of one end of the rubber ring 3, and a second annular insert 9 is formed on one side of the second annular groove 8, wherein the first annular insert 7 is inserted into the second annular groove 8, and the second annular insert 9 is inserted into the first annular groove 6 to realize the connection between the plastic wind ring 4 and the rubber ring 3.

[0022] The flexible wind shield of the utility model modifies the metal ring into a plastic wind shield and adds reinforcing ribs, making the entire wind shield lighter while ensuring strength. The flexible wind shield made of rubber material is connected to the cooling pack of the entire vehicle, which can reduce the relative displacement problem caused by the different vibration amplitudes of the engine and the cooling pack, and reduce the risk of failure of the wind shield breaking.

[0023] At the same time, the plastic air ring and the rubber ring are connected by two radial annular grooves and two inserts, changing the axial U-shaped structure directly riveted to the metal ring to a radial double U-shaped connection structure, which increases the rubber ring's anti-pullout ability, prevents the rubber ring from being worn, and further extends its service life.

[0024] Preferably, multiple reinforcing ribs 5 are evenly distributed on the outer wall of the plastic air ring 4 to further improve the structural strength of the plastic air ring 4, and the multiple reinforcing ribs 5 and the plastic air ring 4 are an integrally molded structure using plastic material, which facilitates production while further improving the structural strength of the plastic air ring 4.

[0025] Preferably, there is interference fit between the first annular insert 7 and the second annular groove 8, and between the second annular insert 9 and the first annular groove 6, so that the connection between the plastic air ring 4 and the rubber ring 3 is more stable without axial movement, further preventing the problem of wear.

[0026] Preferably, the fixing bracket 1 and the plastic air ring 4 are connected by multiple bolts to achieve a detachable connection between the fixing bracket 1 and the plastic air ring 4, which is convenient for disassembly and maintenance.

[0027] Preferably, the inner wall of the rubber ring 3 is an inclined surface with an inner diameter gradually increasing along the side away from the plastic air ring 4; the inner wall of the plastic air ring 4 is an inclined surface with an inner diameter gradually increasing along the side away from the rubber ring 3. This facilitates the connection between the rubber ring 3, the plastic air ring 4, and the pipeline, making it easier to insert the pipeline into the plastic air ring 4 or the rubber ring 3. Furthermore, the wall thickness of the rubber ring 3 gradually decreases along the side away from the plastic air ring 4, making the side of the rubber ring 3 away from the plastic air ring 4 easier to deform, further facilitating the insertion of the pipeline.

[0028] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These modifications and improvements will not affect the effect of the implementation of the present invention and the practicality of the patent.
