[0002] Currently, the roads used for vehicle transportation contain easily dispersed materials such as slag, dust, ash, and willow catkins. During transportation and vehicle startup, due to the low mounting position of the vehicle's fan, the rotation of the engine fan generates airflow, which blows onto the road surface, causing dust to rise from the vehicle. This results in pollution of both the exterior and interior of the vehicle, affecting its cleanliness. Therefore, this problem needs to be addressed. Summary of the Invention

[0003] This application provides an engine fan dustproof wind shield device, an engine, and a vehicle to solve the problem in related technologies where the vehicle fan is mounted at a low position, the rotation of the engine fan generates airflow, and the airflow blown onto the road surface causes dust to rise from the vehicle, resulting in pollution of the vehicle's exterior and interior and affecting the vehicle's cleanliness.

[0004] In a first aspect, an engine fan dustproof shield device is provided, comprising:

[0005] The wind shield body has a wind deflector connected to the side facing the ground on the outer periphery of its shield ring.

[0006] Along the axial direction of the cover ring, the side of the baffle plate near the fan extends axially to form a windproof area, and the projection of the fan along the axial direction of the cover ring is located within the windproof area.

[0007] In this embodiment, the wind shield body has a wind deflector connected to the outer peripheral wall of its side facing the ground. Along the axial direction of the shield, the wind deflector extends axially towards the fan to form a wind-blocking area. The projection of the fan along the axial direction of the shield is located within this wind-blocking area. This effectively blocks the airflow generated by the fan's rotation, preventing the blowing of easily dispersed materials such as slag, dust, and willow catkins. Simultaneously, it provides protection, preventing dust from rising from the vehicle.

[0020] This application provides an engine fan dustproof wind shield device, an engine, and a vehicle. The wind shield body has a wind deflector connected to the outer periphery of its outer ring on the side facing the ground. A wind deflector extends axially along the ring, near the fan, forming a wind-blocking area. The fan's projection along the ring's axial direction lies within this area.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] It should be understood in connection with this application that:

[0031] The radiator shield is part of the cooling system of commercial vehicles. The core function of the radiator shield for diesel engines in commercial vehicles is to enhance airflow and heat dissipation. A large fan in front of the diesel engine provides airflow to the radiator. The radiator shield effectively prevents airflow loss, further improving heat dissipation performance. To quickly preheat the vehicle, especially in winter, many truck drivers choose to cover the radiator with a cloth; this is mainly because diesel engines typically preheat slower than gasoline engines. By installing a shield in front of the radiator, airflow during driving is prevented from blowing directly onto the radiator, thus helping the engine reach its optimal operating temperature more quickly. Furthermore, the cooling fan control method for trucks differs from that of passenger cars; most use a silicone oil clutch to regulate the radiator cooling fan. The characteristics of the silicone oil clutch make it easy to disengage at low temperatures, but during a cold start, the fan will still run at a low speed due to inertia. This is one of the reasons why a shield is needed in front of the radiator.

[0032] However, during transportation and vehicle startup, due to the low mounting position of the engine fan, the rotation of the engine fan generates airflow, which blows onto the road surface, causing dust to rise from the vehicle. This results in pollution of both the exterior and interior of the vehicle, affecting its cleanliness. Therefore, this application provides an engine fan dust shield device to address this problem.

[0033] Please see Figure 1 and Figure 3 An engine fan dustproof shield device, comprising:

[0034] The wind shield body 1 has a wind deflector 2 connected to the side facing the ground on the outer peripheral side wall of its shield ring 100.

[0035] Along the axial direction of the cover 100, the side of the baffle 2 closest to the fan 3 extends axially to form a windproof area, and the projection of the fan 3 along the axial direction of the cover 100 is located within the windproof area. This projection is viewed along the axial direction of the cover 100 and does not include the overall projection of the fan 3.

[0036] With the above settings, the projection of fan 3 is located within the windbreak area, which blocks the airflow generated by the rotation of fan 3 towards the ground, preventing the blowing of easily scattered materials such as slag, dust, dirt, and willow catkins from the ground; at the same time, it plays a protective role, preventing dust from rising from the vehicle.

[0037] The principle can be found in the appendix. Figure 4 The airflow directed toward the ground is represented by multiple radial arrows, which block the airflow directed toward the ground and then guide the airflow in the width and length directions of the vehicle.

[0038] In some preferred embodiments, the wind deflector 2 is provided in the following two configurations:

[0039] Form 1

[0040] The wind deflector 2 includes a rectangular plate 203, the center line of the top of the rectangular plate 203 is connected to the target position at the bottom of the outer peripheral side wall of the cover ring 100; the target position is the axial area corresponding to the bottom end of the vertical diameter of the cover ring 100.

[0041] In Form 1, see Appendix Figure 5 It forms a blocking plane area, preventing the airflow from blowing directly onto the ground, thus effectively improving the situation.

[0042] Form Two

[0043] The wind deflector 2 includes an arc-shaped wind deflector, which is concentrically arranged with the cover ring 100. While the first design initially addresses the problem of easily dispersed materials such as slag, dust, and willow catkins being blown up from the ground, this airflow remains unutilized, for example, for engine cooling. The arc-shaped wind deflector guides this airflow upwards towards the engine for cooling. Furthermore, this structure facilitates installation and connection with the cover ring 100. The arc-shaped wind deflector structure also enhances the overall strength.

[0044] It should be noted that the arc length of the curved wind deflector can be reasonably adjusted and avoided according to the specific layout of pipelines in the vehicle chassis. Therefore, there is no specific limitation on its arc length.

[0045] Furthermore, in form two, there are two more refined structures, as follows:

[0046] Structure 1

[0047] Reference Appendix Figure 1 Appendix Figure 2 Appendix Figure 3 The curved wind deflector includes a curved wind deflector portion 200 and a curved connecting strip 201; the curved connecting strip 201 has an L-shaped cross-section; the curved wind deflector portion 200 is connected to the cover ring 100 via the curved connecting strip 201. The curved connecting strip 201 and the cover ring 100 are connected by rivets; or, the curved connecting strip 201 and the cover ring 100 are connected by bolts; or, the curved connecting strip 201 is welded to the cover ring 100.

[0048] Along the axial direction of the cover ring 100, the arc-shaped windbreak portion 200 has an air guide rolled edge portion 202 on the side away from the cover ring 100. The air guide rolled edge portion 202 further improves the air guiding path.

[0049] Structure 2

[0050] The arc-shaped wind deflector includes an arc-shaped wind deflector 200; on the axial direction of the cover ring 100, one side of the arc-shaped wind deflector 200 conforms to the cover ring 100 and is connected by rivets or bolts.

[0051] In both Structure 1 and Structure 2, the curved wind deflector can be integrally cast with the shroud ring 100. This allows it to be installed not only on existing vehicle wind deflector bodies 1, but also cast as a whole during the vehicle manufacturing stage.

[0052] In structure one, the arc-shaped connecting strip 201 creates a certain gap between the arc-shaped windbreak part 200 and the outer ring formed by the movement trajectory of the fan 3, thus avoiding affecting the original heat dissipation effect of the fan 3.

[0053] The wind deflector 2 is made of fiberglass, aluminum alloy, or steel. Fiberglass, scientifically known as fiber-reinforced plastic, commonly called FRP (Fiber Reinforced Plastics), is a type of fiber-reinforced composite plastic. It generally refers to reinforced plastics using glass fibers to strengthen unsaturated polyester, epoxy resin, and phenolic resin matrices, with glass fibers or their products as the reinforcing material. This is different from tempered glass. Due to the different types of resins used, there are polyester fiberglass, epoxy fiberglass, and phenolic fiberglass. Fiberglass is lightweight yet hard, non-conductive, stable in performance, has high mechanical strength, low recyclability, and is corrosion-resistant, meeting the requirements for lightweight, strength, and protection. Sound insulation cotton can also be installed on the wind deflector 2 to reduce the transmission of noise and vibration.

[0054] This application also proposes an engine comprising: an engine fan dust shield device. (Reference) Figure 6 As shown.

[0055] This application also proposes a vehicle comprising an engine. With the above-described configuration, the projection of the fan 3 is located within the windbreak area, thereby blocking the airflow generated by the fan 3 and preventing the stirring up of easily dispersed materials such as dirt, dust, and willow catkins; simultaneously, it provides protection, preventing dust from being generated by the entire vehicle.

[0056] Based on the above explanation, the wind shield body 1 does not need to be sent to a modification shop for secondary modification. The wind deflector 2 can be added directly, which is highly feasible and simple to install. The wind deflector 2 is integrated with the fan wind shield, which has high reliability and a high degree of standardization.

[0057] The wind deflector 2 features an integrated arc mounting surface. This structure strengthens the dust baffle assembly, improves overall vehicle reliability, and enhances assembly efficiency, effectively suppressing dust from the vehicle.

[0058] Vehicles equipped with air shrouds include heavy-duty trucks and engine cooling systems. The main function of the air shroud is to protect the engine's cooling fan from direct impact from the external environment, while also improving heat dissipation efficiency. An air shroud typically consists of a fan guard ring and annular brushes. The fan guard ring houses the fan, while the annular brushes are fastened to the fan guard ring with fasteners, serving to dampen vibrations and prevent the fan blade tips from contacting the fan guard ring.

[0059] Current wind shield design features include:

[0060] Vibration damping design: The transition ring of the wind shield is equipped with a vibration damping part, which absorbs the vibration of the engine and radiator during operation through elastic vibration damping, prevents it from falling off, and improves installation strength and reliability;

[0061] Gap design: The ring-shaped brush design ensures a sufficiently small gap (3-8mm) between the shroud and the fan blade tip, improving heat dissipation efficiency while preventing the fan blade tip from contacting the shroud.

[0062] The specific application scenarios and effects of the wind shield include:

[0063] Improve heat dissipation efficiency: By reducing the contact between the fan blade tips and the air shield, the heat dissipation efficiency of the radiator is improved, thereby increasing the engine's working efficiency and lifespan;

[0064] Vibration reduction and anti-fall-off: The vibration reduction design prevents the wind shield from falling off during operation, ensuring the stable operation of the engine cooling system.

[0065] Therefore, to meet the above design requirements, the wind deflector 2 is made of fiberglass. The curved wind deflector includes a curved wind deflector part 200 and a curved connecting strip 201. The cross-section of the curved connecting strip 201 is L-shaped. The curved wind deflector part 200 is connected to the cover ring 100 through the curved connecting strip 201. The curved connecting strip 201 and the cover ring 100 are connected by rivets; or, the curved connecting strip 201 and the cover ring 100 are connected by bolts; or, the curved connecting strip 201 is welded to the cover ring 100. In the axial direction of the cover ring 100, a guide curled edge part 202 is provided on the side of the curved wind deflector part 200 away from the cover ring 100. The guide curled edge part 202 further improves the air guiding path; the curved connecting strip 201 ensures that there is a certain gap between the curved wind deflector part 200 and the outer ring formed by the movement trajectory of the fan 3, avoiding affecting the original heat dissipation effect of the fan 3.
