[0002] The air shield (also known as a fan guard or air collector ring) is a key component of the automotive engine cooling system. Its core function is to optimize airflow distribution, improve cooling efficiency, and ensure the safety and stability of engine operation. By wrapping around the fan, the air shield forms an airflow channel, allowing the airflow generated by the fan to flow more concentratedly to the radiator. This design can increase air pressure and air volume, ensuring that the radiator surface receives uniform airflow coverage, thereby making full use of the heat dissipation area and improving cooling efficiency.

[0003] The shortcomings of existing technology: Existing air shields are usually one-piece model structures. Due to the high temperature and vibration generated during engine use, the air shield may deform due to thermal expansion and contraction or vibration, or the installation position may be offset, affecting the performance of the air shield. In addition, the existing air shields are very inconvenient to disassemble after installation and cannot adapt to the needs of different vehicle models and installation environments. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multifunctional detachable air guard ring to solve the problem that the existing air guard rings in the background art may deform due to thermal expansion and contraction or vibration when the engine is running, or the installation position may be offset, affecting the performance of the air guard ring.

[0011] Preferably, four connecting blocks are fixedly connected to both the first mounting bracket and the second mounting bracket, and a buffer pad is fixedly connected to the end of each connecting block away from the connecting structure.

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

[0013] 1. This utility model features a first mounting bracket and a second mounting bracket, which are respectively connected to the radiator and the engine. The first and second mounting brackets are connected by a connecting structure. The distance between the first and second connecting sleeves can be adjusted according to the specific installation positions of the radiator and the engine, making the air guard suitable for different vehicle models.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The multifunctional detachable windshield involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] This utility model provides a multifunctional detachable windshield ring, such as Figure 1 - Figure 4 As shown, the device includes a first mounting bracket 1 and a second mounting bracket 2. A connecting structure 3 is provided between the first mounting bracket 1 and the second mounting bracket 2. Reinforcing plates 4 are fixedly connected to the outer surfaces of both the first mounting bracket 1 and the second mounting bracket 2. A fan bracket 5 is fixedly connected to the inner wall of the first mounting bracket 1. A positioning shaft 6 is provided at the central axis of the fan bracket 5. The first mounting bracket 1 is connected to the radiator to form an air duct inlet, and the second mounting bracket 2 is connected to the engine to form an air duct outlet. The fan in the radiator is mounted on the fan bracket 5. At the same time, the positioning shaft 6 determines the installation position of the fan to prevent it from shifting during high-speed operation and causing damage due to friction with the air guard.

[0022] Furthermore, such as Figure 1 and Figure 2As shown, the connecting structure 3 includes a first connecting sleeve 31 fixedly connected to the top of the first mounting bracket 1, and a second connecting sleeve 32 fixedly connected to the bottom of the second mounting bracket 2. The inner walls of the first connecting sleeve 31 and the second connecting sleeve 32 are jointly provided with a protective ring 33. The top of the first connecting sleeve 31 and the bottom of the second connecting sleeve 32 are each provided with four buffer grooves 34. The protective ring 33 is made of a flexible material such as a rubber ring. A protective ring 33 of appropriate size is selected and placed between the first connecting sleeve 31 and the second connecting sleeve 32 to ensure the sealing between the two. During the use of the radiator, when the cooling fan rotates at high speed, debris or gravel may fly everywhere. The protective ring 33 prevents the debris from flying everywhere and causing wear on the inner wall of the protective ring. At the same time, the protective ring 33 reduces the noise generated by the cooling fan during use.

[0023] Furthermore, such as Figure 2 and Figure 3 As shown, the inner cavities of the two adjacent buffer grooves 34 are equipped with two telescopic rods 35. The first connecting sleeve 31 and the second connecting sleeve 32 are connected by the telescopic rods 35. According to the installation distance between the radiator and the engine, the distance between the first connecting sleeve 31 and the second connecting sleeve 32 is adjusted to reduce the installation gap between the first mounting bracket 1 and the second mounting bracket 2. During adjustment, the telescopic rods 35 extend and retract, controlling the relative position of the air shield with the radiator and the engine, ensuring that the gap and position after installation are within a reasonable range. This effectively improves the accuracy of the air shield connection and the convenience of disassembly and assembly, making the relative position between the radiator and the engine more accurate after installation. At the same time, the buffer grooves 34 can reduce the impact of high temperature or vibration. The buffer grooves 34 and the telescopic rods 35 play a buffering and shock-absorbing role, avoiding the high temperature or vibration generated during engine use from affecting the performance of the air shield.

[0024] Furthermore, such as Figure 3 and Figure 4 As shown, the inner walls of the first mounting bracket 1 and the second mounting bracket 2 are both fixedly connected with inner tubes 7. The inner tubes 7 are inserted into the inner walls of the first connecting sleeve 31 and the second connecting sleeve 32. A sealing ring 8 is fixedly connected to the inner wall of the inner tube 7. After the first mounting bracket 1 and the second mounting bracket 2 are installed, they are connected to the connecting structure 3 through the inner tubes 7. The connection method is an internal insertion method. At the same time, the connection between the inner tube 7 and the first connecting sleeve 31 and the second connecting sleeve 32 is sealed with a sealing ring 8, so that the airflow can accurately pass through the air duct inlet and air duct outlet.

[0025] Furthermore, such as Figure 3 As shown, the two inner tubes 7 are connected to the upper and lower ends of the protective ring 33. The inner wall of the protective ring 33 is set to be arc-shaped. The inner tubes 7 ensure the flatness of the inner wall of the protective ring after installation. The arc-shaped inner wall of the protective ring 33 reduces the exhaust resistance when the fan is working and ensures the smoothness of airflow.

[0026] Furthermore, such as Figure 1 and Figure 3 As shown, a connecting hole 9 is provided in the middle of the reinforcing plate 4. The two adjacent reinforcing plates 4 are movably connected. The inner cavities of the two adjacent connecting holes 9 are connected and are connected together by bolt connectors 10. After the first mounting bracket 1 and the second mounting bracket 2 are installed and their positions are adjusted, the positions of the two adjacent reinforcing plates 4 are also adjusted accordingly. After the adjustment is completed, the bolt connectors 10 are inserted through the two connecting holes 9 to fix the positions of the two adjacent reinforcing plates 4. At the same time, the installation positions of the first mounting bracket 1 and the second mounting bracket 2 are reinforced to ensure the accuracy and stability of the installation position of the windshield ring.

[0027] Furthermore, such as Figure 1 As shown, four connecting blocks 11 are fixedly connected to both the first mounting bracket 1 and the second mounting bracket 2. A buffer pad 12 is fixedly connected to the end of the connecting block 11 away from the connecting structure 3. When the first mounting bracket 1 and the second mounting bracket 2 are installed, bolts and nuts are used to pass through the connecting blocks 11. During installation, the buffer pad 12 on the connecting block 11 contacts the radiator fan or engine. The buffer pad 12 is made of rubber, which increases the tightness and firmness between the connecting block 11 and the installation position, and effectively reduces the vibration of the air shield during use, so as to prevent the installation position of the first mounting bracket 1 and the second mounting bracket 2 from becoming loose.

[0028] The working principle of this utility model is as follows: First, the first mounting bracket 1 is connected to the radiator to form an air duct inlet, and the second mounting bracket 2 is connected to the engine to form an air duct outlet. During installation, the buffer pad 12 on the connecting block 11 contacts the radiator fan or engine. Bolts and nuts are used to pass through the connecting block 11, so that the first mounting bracket 1 and the second mounting bracket 2 are respectively fixed to the radiator and the engine. The buffer pad 12 is made of rubber to increase the tightness and firmness between the connecting block 11 and the installation position, and at the same time effectively reduce the vibration of the air shield during use, which could cause the installation positions of the first mounting bracket 1 and the second mounting bracket 2 to loosen. After the first mounting bracket 1 and the second mounting bracket 2 are installed, the distance between the first connecting sleeve 31 and the second connecting sleeve 32 is adjusted according to the positional relationship between the radiator and the engine. During adjustment, the telescopic rod 35 extends and retracts. By controlling the relative position of the radiator shield with the fan and engine, the gap and position after installation are ensured to be within a reasonable range, effectively improving the accuracy of the radiator shield connection and the convenience of disassembly and assembly. This makes the relative position between the radiator and engine more accurate after installation. During engine use, the buffer groove 34 and telescopic rod 35 provide buffering and shock absorption, preventing the radiator shield from deforming due to thermal expansion and contraction or displacement of the installation position caused by high temperature or vibration generated during engine use, which would affect the performance of the radiator shield. After adjustment, the position between the two adjacent reinforcing plates 4 is also adjusted accordingly. Finally, the bolt connector 10 is inserted through the two connecting holes 9 to fix the position of the two adjacent reinforcing plates 4. At the same time, the installation positions of the first mounting bracket 1 and the second mounting bracket 2 are reinforced, effectively improving the accuracy of the radiator shield connection and the convenience of disassembly and assembly.

[0029] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
