It should be noted that the bottom plate of the cab 300 is arc-shaped, and the portion near the front of the vehicle is low, and the portion near the rear of the vehicle is high, so that an installation cavity is formed below the rear of the cab 300, and the engine 400 is located in the installation cavity. In this case, the upper side and the front side of engine 400 are opposite to the floor of cab 300, which can insulate noise transmitted upward and forward, reducing the interference of noise to the driver, and sound absorbing materials such as foam and heat insulating pad are also provided in the gap between the front side of engine 400 and the floor of cab 300, thereby further reducing the influence of noise. It can be understood that the vehicle of the present application further includes components such as wheels, a compartment and a transmission system, and the specific components are subject to ensure that the vehicle can be used normally, and the embodiments of the present application are not limited herein.

The engine sound-insulating device 100 of the present application is divided into the sound-insulating member 110 and the mud guard member 120, the sound-insulating member 110 is disposed on the vehicle frame 200, the mud guard member 120 is disposed on the cab 300, and the open spaces on the left and right sides of the engine 400 can be closed to insulate sound by abutting the sound-insulating member 110 and the mud guard member 120. In addition, a bottom plate of cab 300 is arranged above engine 400 for sound insulation, and a bottom plate of cab 300, and sound-absorbing materials such as foam and a heat-insulating pad are arranged in front of engine 400 for sound insulation, so that the front upper left and right directions of engine 400 can be closed by additionally arranging engine sound insulation device 100 on the vehicle, interference of noise to a driver in the driving process is reduced, and driving safety is guaranteed. Further, a cabin may be provided on frame 200 behind engine 400, and the cabin may also provide a sound insulation effect against noise.

As one possible embodiment, the outer contour of the baffle 110 surrounds the outer periphery of the engine 400.

It should be noted that, through the above arrangement, the projection of the engine 400 on the sound insulating member 110 can be completely located within the outer contour range of the sound insulating member 110, so that the noise transmitted to the left and right sides by the engine 400 can be fully intercepted and isolated by the sound insulating member 110, and the sound insulating effect is further improved.

As one possible embodiment, the outer contour of the fender 120 surrounds the outer periphery of the engine 400.

It should be noted that, through the above arrangement, the projection of the engine 400 on the fender 120 can be completely located within the range of the outer contour of the fender 120, so that the noise transmitted to the left and right sides by the fender 120 can be fully intercepted and isolated by the fender 120 after the noise is first isolated by the fender 110, and the noise is isolated for the second time, thereby further improving the sound isolation effect.

Meanwhile, the mud guard 120 can also protect the outer wall surface of the sound insulation member 110, so that when a vehicle passes through a muddy road, the outer wall surface of the sound insulation member 110 is splashed with mud, and further, the matching effect of the mud guard 120 is prevented from being influenced by the fact that the mud is stained on the outer wall surface of the sound insulation member 110.

As an implementation, at least a portion of the baffle 110 is positioned between the fender 120 and the engine 400, and the baffle 110 abuts the fender 120.

It should be noted that, by disposing the sound insulating member 110 between the mud guard 120 and the engine 400, the mud guard 120 not only can exert a sound insulating effect on noise generated by the engine 400, but also can prevent the outer wall surface of the sound insulating member 110 from being splashed with sludge. Through noise insulation 110 and fender mud piece 120 butt, can plug up the clearance between noise insulation 110 and the fender mud piece 120, avoid the noise to transmit away through the clearance between noise insulation 110 and the fender mud piece 120, and then reach the purpose that improves syllable-dividing effect.

As an implementation, the fender 120 includes a fender 121 and a fender skin 122, the fender 121 is connected to the fender skin 122, the fender skin 122 is located between the fender 121 and the sound insulator 110, and at least a part of the sound insulator 110 abuts against the fender skin 122.

It should be noted that, by dividing the fender 120 into two parts, namely, the fender 121 and the fender skin 122, and abutting the sound insulation member 110 against the fender skin 122, the frictional wear of the fender 120 can be completely transferred to the fender skin 122, and when the fender 120 is in frictional failure or fatigue failure, only the fender skin 122 needs to be shifted, so that the material cost can be reduced. Meanwhile, replacing the fender 122 mounted on the fender 121 is relatively easy compared to replacing the fender 121 mounted on the cab 300, and it is also possible to reduce labor cost and time cost.

As an embodiment, the sound insulator 110 is provided with a cavity therein, and the cavity is filled with the foaming material 111.

It should be noted that, this arrangement can make the sound insulating member 110 have a double-layer structure, and when noise passes through the sound insulating member 110, the sound insulating effect can be significantly improved by performing sound insulation twice. As an implementation manner, the cavity may be filled with a foam material 111, the foam material 111 is a loose and porous elastic material, which may have a good sound absorption effect, and when the sound insulation member 110 is deformed by an impact, the foam material 111 may also play a role in buffering, thereby reducing damage to the sound insulation member 110 caused by the impact. Specifically, the foaming material 111 may be an organic foaming material or an inorganic foaming material.

As an achievable embodiment, the wall thickness of the baffle 110 ranges from 1.5 to 2.5 mm.

It should be noted that, the wall thickness of the sound-insulating member 110 is 1.5-2.5mm, which not only can avoid the strength and sound-insulating effect of the sound-insulating member 110 being insufficient due to too thin wall thickness, but also can avoid the waste of materials and the increase of load of the vehicle due to too thick wall thickness. Illustratively, the thickness of the acoustic barrier 110 may be 1.5mm, 1.8mm, 2mm, 2.3mm, 2.5mm, and the like. When the thickness of the soundproof member 110 is less than 1.5mm, the soundproof member 110 is not only insufficient in strength due to the excessively thin thickness, so that the soundproof member 110 is easily deformed under the external force, but also reduced in soundproof effect on noise due to the excessively thin thickness. When the thickness of the soundproof member 110 is greater than 2.5mm, the soundproof member 110 is not only too thick to cause waste of material, but also too thick to cause an increase in load of the vehicle. In practical use, the user can select a specific value of the thickness of the sound-insulating member 110 within the above range according to the needs, which is not limited by the embodiment.

As an implementation, the fender 122 is U-shaped in cross-section.

It should be noted that, by providing the cross section of the mud flap 122 with a U-shaped structure, a greater elastic deformation capability of the mud flap 122 can be achieved. When the vehicle has travelled through unevenness's road surface, when the automobile body takes place to rock or violent vibrations, fender 121 and noise insulation 110's interval constantly changes, and elastic deformation takes place more easily for the fender mud skin 122 of U-shaped structure, and its deflection can change along with the change of interval, guarantees that fender mud skin 122 can and noise insulation 110 butt all the time for the vehicle also has good syllable-dividing effect under abominable driving environment.

As one possible implementation, the fender 122 includes rubber.

It should be noted that, by setting the mud guard 122 as a rubber member, the mud guard has a large elasticity, can be deformed greatly by a small external force, and can be restored to its original shape after the external force is removed. When the vehicle drives over a bumpy road surface, the mud guard 122 can automatically adapt to the change of the distance between the mud guard 121 and the sound insulation piece 110 through the elastic deformation of the mud guard 122, so that the mud guard 122 and the sound insulation piece 110 are always abutted in the driving process, and the vehicle is further ensured to have a good sound insulation effect under a severe driving environment. Simultaneously, set up to the rubber spare through keeping off the mud skin 122, make it have great elasticity, when still can reducing fender mud skin 122 and noise insulation 110 butt, cause the degree of frictional wear to noise insulation 110 surface, and then improve noise insulation 110's syllable-dividing effect and life.

Specifically, as a preferred embodiment, the material of the mud guard 122 may be Thermoplastic Vulcanizate (TPV). The arrangement can enable the mud guard 122 to have the advantages of impact resistance and shock resistance, and when the vehicle shakes or shakes violently, the damage degree of the mud guard 122 between the mud guard 121 and the sound insulation member 110 can be obviously reduced; it is also possible to provide the mud guard 122 with good flexibility, and to improve the buffering effect between the mud guard 121 and the soundproof member 110, whose relative positions are changed, when the vehicle is shaken or violently shaken.

As one possible embodiment, the sound insulator 110 comprises a plastic member.

It should be noted that, by providing the sound insulating member 110 as a plastic member, not only the weight of the sound insulating member 110 can be reduced, the load of the vehicle can be reduced, but also the difficulty and material cost for manufacturing the sound insulating member 110 can be reduced. Meanwhile, the sound insulation member 110 is formed as a plastic member, which is better in corrosion resistance and sound insulation effect than a metal member.

Specifically, as a preferred embodiment, the material of the sound-insulating member 110 may be High Density Polyethylene (HDPE). The arrangement can ensure that the sound insulation piece 110 has good wear resistance and electrical insulation, thereby being beneficial to reducing friction damage and preventing water; the sound insulation member 110 can also have good heat resistance and cold resistance, and is beneficial to being used in severe environment; the sound absorption and insulation effect is good, and the influence of noise on a driver is favorably reduced; the sound insulator 110 is also chemically stable, and is insoluble in any organic solvent at room temperature, and is resistant to corrosion by acids, alkalis, and various salts.

Further, the mudguard 121 includes a plastic member.

It should be noted that, by providing the mudguard 121 as a plastic member, not only the weight of the mudguard 121 can be reduced, the load of the vehicle can be reduced, but also the difficulty and material cost for manufacturing the mudguard 121 can be reduced. Meanwhile, the mudguard 121 is formed as a plastic member, which is better in corrosion resistance and sound insulation effect than a metal member.

Specifically, as a preferred embodiment, polypropylene (PP) may be used as the material of the mudguard 121. This arrangement can provide chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties, and good high-wear processability to the fender 121.
