Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to fan blade assemblies, engine fans, and vehicles. Background Technology

[0002] The cooling fan is a crucial component of the engine cooling system. Its performance directly impacts the engine's heat dissipation, thus affecting its overall performance. Inappropriate fan selection can lead to insufficient or excessive cooling, deteriorating the engine's operating environment and consequently impacting its performance and lifespan.

[0003] For traditional ring fans, the fan frame has an outer cylindrical surface and an outer conical surface. The ends of the fan blades are connected to the inner surface of the outer cylindrical surface. Because the outer cylindrical surface of the fan frame is relatively long, when the vehicle is driving on muddy roads, mud will accumulate at the junction of the fan blades on the engine fan and the outer cylindrical surface of the fan frame. After the mud cools and solidifies, it forms mud blocks, causing the imbalance of the engine fan to exceed the limit, thus affecting the reliability of the engine.

[0004] Therefore, there is an urgent need for fan blade assemblies, engine fans, and vehicles to solve the above problems. Utility Model Content

[0005] According to one aspect of the present invention, the present invention provides a fan blade assembly that ensures that no mud or impurities accumulate at the junction between the fan blade and the fan frame, thereby maintaining the imbalance of the engine fan and the reliability of the engine.

[0037] like Figures 1-3 As shown, in this embodiment, the fan blade assembly includes a fan frame, a hub 3, fan blades 4, and a guide plate 5. The fan frame includes a fan frame body 1 and a guide ring 2, which is connected to the fan frame body 1. The guide ring 2 has an air inlet 21, and the fan frame body 1 has an air outlet 11. The hub 3 is located inside the fan frame, and the fan blades 4 are disposed between the guide ring 2 and the hub 3. The fan blades 4 have a first end 41 and a second end 42, with the first end 41 connected to the hub 3. The guide plate 5 is connected between the guide ring 2 and the second end 42, and is inclined towards the air inlet 21 along the extending direction of the fan blades 4. Specifically, the fan frame has a ring structure, and the two ends of the fan frame are the air inlet 11 and the air outlet 11, respectively. The guide ring 2 is fixedly connected to the fan frame body 1. Along the circumferential direction of the guide ring 2, a fan blade 4 is disposed between the guide ring 2 and the hub 3. The fan blade 4 is inclined relative to the end face of the hub 3. The drive motor drives the hub 3 to rotate, and the air generated by the fan blade 4 flows from the air inlet 21 to the air outlet 11. The first end 41 of the fan blade 4 is fixedly connected to the outer circumference of the hub 3, and the second end 42 of the fan blade 4 is fixedly connected to the guide plate 5. (Refer to...) Figure 3 Along the extension direction of the fan blade 4, the guide plate 5 is tilted to the right and connected to the guide ring 2. During operation, when mud and impurities fall onto the fan blade 4, under the action of the fan's centrifugal force, the mud and impurities will be discharged to the outside of the fan frame along the guide plate 5 and the guide ring 2. The guide ring 2 and the guide plate 5 play a guiding role, thereby ensuring that mud and impurities do not accumulate at the junction between the fan blade 4 and the fan frame, and always maintaining the imbalance of the engine fan and the reliability of the engine.

[0038] Furthermore, continue to refer to Figures 1-3 The guide ring 2 has a curved surface structure. Specifically, along the direction from the air outlet 11 to the air inlet 21, the diameter of the guide ring 2 gradually increases. Compared with the traditional ring fan, the curved surface length of the guide ring 2 is increased, that is, the length of the outer ring conical surface is increased, and the straight surface length of the fan frame body 1 itself is reduced, that is, the length of the outer ring cylindrical surface is reduced. When mud and impurities fall onto the fan blade 4, under the action of the fan's centrifugal force, the mud and impurities are discharged outward in sequence along the inclined guide plate 5 and the curved guide ring 2. The guide ring 2 and the guide plate 5 play a guiding role, ensuring that mud and impurities do not accumulate at the junction between the fan blade 4 and the fan frame.

[0039] Furthermore, continue to refer to Figures 1-3 Along the direction from the second end 42 toward the guide ring 2, the width of the guide plate 5 gradually increases. Specifically, the guide plate 5 has an inverted trapezoidal structure, that is, the width of the end of the guide plate 5 near the fan blade 4 is smaller than the width of the end near the guide ring 2. During normal operation, mud and impurities fall onto the fan blade 4. Then, under the action of the centrifugal force of the fan, the mud and impurities are quickly discharged outward along the extension direction of the fan blade 4 through the gradually widening guide plate 5 and the curved guide ring 2, ensuring that no mud or impurities accumulate at the junction between the fan blade 4 and the fan frame. The guide ring 2 and the guide plate 5 play a guiding role.

[0040] Furthermore, continue to refer to Figures 1-3 The flow guide plate 5 and the guide ring 2 are smoothly connected. Specifically, the connection between the flow guide plate 5 and the guide ring 2 is smooth, ensuring that mud impurities can be smoothly and quickly discharged through the flow guide plate 5 and the guide ring 2 under the action of centrifugal force. The guide ring 2 and the flow guide plate 5 play a guiding role, and no mud impurities are left at the junction between the fan blade 4 and the fan frame, making it smooth and silky.

[0041] Furthermore, continue to refer to Figures 1-3 The guide vane 5 and the fan blade 4 are integrally formed. Specifically, the guide vane 5 and the fan blade 4 are integrally formed by casting or other methods, resulting in high structural strength, resistance to breakage, and reduced installation costs.

[0042] Furthermore, continue to refer to Figures 1-3 The guide plate 5 and the guide ring 2 are welded together. Specifically, the guide plate 5 and the guide ring 2 are fixedly connected by welding. The connection is firm and the transition of the weld is smooth, ensuring that mud impurities can pass through quickly without getting stuck, and without affecting the guiding effect of the guide plate 5 and the guide ring 2 themselves or the transition effect between them.

[0043] Furthermore, continue to refer to Figures 1-3 There are multiple fan blades 4, which are spaced apart along the circumference of the guide ring 2. There are also multiple guide plates 5, which are respectively positioned between the fan blades 4 and the guide ring 2. Specifically, during operation, when mud and impurities fall onto the multiple fan blades 4, under the action of centrifugal force, the mud and impurities will be simultaneously discharged to the outside of the fan frame along the corresponding guide plates 5 and guide ring 2 of each fan, ensuring that no mud or impurities accumulate at the junction of the fan blades 4 and the fan frame, thus guaranteeing the reliability of the engine.

[0044] This embodiment also provides an engine fan, including a motor, a protective cover, and the aforementioned fan blade assembly. The protective cover is fitted over the fan blade assembly, the fixed end of the motor is mounted on the protective cover, and the driving end of the motor is connected to the fan blade assembly and used to drive the fan blade assembly to rotate. Specifically, the protective cover is usually welded from steel plates and serves as the outer shell of the fan blade assembly, covering the outer periphery of the fan frame for protection. The motor is the driving power source, which drives the fan blade assembly to rotate and generate wind power through power supply. The output end of the motor is connected to the hub 3 and used to drive the hub 3 to rotate, causing the fan blades 4 and the fan frame to rotate. Under the action of the fan blades 4, a strong wind is generated, flowing from the air inlet 21 to the air outlet 11.

[0045] This embodiment also provides a vehicle, including an engine and the aforementioned engine fan, which is used to cool the engine. Specifically, during operation, when mud and impurities fall onto the engine fan, under the centrifugal force of the fan, the mud and impurities are discharged to the outside of the fan frame under the guidance of the guide plate 5 and the guide ring 2, ensuring that no mud or impurities accumulate at the junction between the fan blade 4 and the fan frame, thereby maintaining the imbalance of the engine fan and the reliability of the engine.
