Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Traditional engine compartment soundproofing solutions typically involve installing a soundproof cover on top of the engine, which can only reduce near-field noise above the engine but cannot effectively block noise around the engine. The following is for reference. Figures 1-4 Describes a vehicle according to an embodiment of the present utility model.

[0020] The vehicle 1 according to the present invention includes: a frame, an engine 11, a body component 12, and a sound insulation component 13. The engine 11 is disposed on the frame; the body component 12 is connected to the frame and is disposed around at least a portion of the outer periphery of the engine 11; the sound insulation component 13 is disposed on the side of the body component 12 facing the engine 11 and is located at the bottom and / or side of the engine 11 to absorb noise transmitted by the engine 11.

[0021] According to the present invention, the vehicle 1 has an engine 11 mounted on a frame. The frame has two longitudinal beams that extend in the length direction of the vehicle body and are spaced apart from each other in the width direction of the vehicle body. The engine 11 is located between the longitudinal beams. The two ends of the body component 12 are connected to the two longitudinal beams on the frame. When the body component 12 is assembled with the frame, the body component 12 surrounds at least part of the outer periphery of the engine 11. The body component 12 can be simply regarded as a protective cover for the engine 11. The body component 12 is also provided with a sound insulation component 13. The sound insulation component 13 can be arranged on the side of the engine 11 (i.e., both sides in the width direction of the vehicle body) and the bottom of the engine 11. When the engine 11 is working, the sound insulation component 13 can absorb the noise transmitted by the vibration of the engine 11 and prevent the noise from being further transmitted to the interior of the vehicle body, thereby improving the driving experience of the vehicle.

[0022] Vehicle 1 incorporates a body component 12 surrounding at least a portion of the outer periphery of engine 11, and a sound-insulating component 13 located at the bottom and / or side of engine 11 on the side of body component 12 facing engine 11. This allows vehicle 1 to absorb noise transmitted from engine 11 from multiple locations, helping to reduce noise transmitted from engine 11 to the surrounding environment during operation and improving the overall quietness of the vehicle. Furthermore, the sound-insulating component 13 is directly positioned at the bottom and / or side of engine 11, allowing for more effective noise blocking and absorption, thus significantly improving the sound insulation effect of the sound-insulating component 13.

[0023] Since the body component 12 is arranged around at least part of the outer periphery of the engine 11, and the sound insulation component 13 can be arranged at the bottom and / or side of the engine 11, the arrangement of the sound insulation component 13 is flexible. In actual assembly, the position of the sound insulation component 13 can be adjusted and optimized according to different vehicle models and the specific layout of the engine 11 to adapt to various complex vehicle structures.

[0024] According to one embodiment of the present invention, the sound insulation component 13 includes: a housing 131 and a sound-absorbing component 132. The housing 131 is disposed on the body component 12, and a sound-absorbing cavity is formed inside the housing 131. The sound-absorbing component 132 is disposed in the sound-absorbing cavity to absorb the noise transmitted from the engine 11 to the housing 131, and a cavity 133 is formed between the sound-absorbing component 132 and the body component 12.

[0025] As a structure for absorbing engine noise 11, the sound insulation component 13's construction affects the overall noise reduction effect of the vehicle 1. Specifically, the sound insulation component 13 has a housing 131, within which a sound-absorbing cavity is provided. A sound-absorbing component 132 is installed within the sound-absorbing cavity. The sound-absorbing component 132 can be constructed using a special sound-absorbing material so that it can effectively absorb the noise transmitted from the engine 11 to the housing 131, thereby significantly reducing the outward propagation of noise generated during engine operation, reducing noise pollution to the surrounding environment, and improving the noise reduction effect of the vehicle 1. A cavity 133 is formed between the sound-absorbing component 132 and the main body component 12. The structure of the cavity 133 further optimizes the sound absorption performance of the sound insulation component 13. For example, compared to the solid housing 131, the cavity 133 can reduce the sound wave transmission speed and slow down the outward transmission of noise; or a vacuum environment can be constructed within the cavity 133 to hinder noise transmission. The cavity 133 and the sound-absorbing component 132 work together to more effectively absorb and consume noise energy, thereby improving the overall sound insulation and noise reduction effect of the vehicle 1.

[0026] According to one embodiment of the present invention, the sound insulation component 13 is provided with a plurality of sound-absorbing units 130, each sound-absorbing unit 130 is provided with a sound-absorbing element 132, and a sound-absorbing gap 136 is formed between two adjacent sound-absorbing units 130. Figures 2-3As shown, each sound insulation component 13 is provided with multiple sound-absorbing units 130. Each sound-absorbing unit 130 contains a sound-absorbing cavity and a sound-absorbing component 132 housed within the cavity. The design of multiple sound-absorbing units 130 improves the sound absorption effect of each sound insulation component 13, thereby improving the overall sound insulation and noise reduction effect of the vehicle 1. The sound-absorbing gap 136 formed between two adjacent sound-absorbing units 130 allows noise generated by the engine 11 to be further reflected and scattered when transmitted to the sound insulation component 13. This increases the opportunity and time for sound to come into contact with the sound-absorbing component 132, making the noise energy more effectively absorbed and consumed during propagation, further optimizing the noise absorption effect.

[0027] According to one embodiment of this utility model, the sound-absorbing unit 130 extends toward the engine 11 and its thickness gradually decreases in the extending direction. Extending toward the engine 11 brings the sound-absorbing unit 130 closer to the noise source of the engine 11, helping to guide the noise along the extending direction of the sound-absorbing unit 130, and gradually absorbing it during propagation, thus optimizing the noise absorption path and improving sound absorption efficiency. Simultaneously, the gradually decreasing thickness of the sound-absorbing unit 130 in the extending direction forms a wedge-like structure. This variation in thickness makes the structure of the sound-absorbing unit 130 more complex, allowing noise to be reflected at more angles on the sound-absorbing unit 130, increasing the opportunity and time for sound to contact the sound-absorbing component 132, and enabling the noise energy to be absorbed and consumed more effectively during propagation, further optimizing the noise absorption effect.

[0028] Furthermore, the thickness of the sound-absorbing unit 130 gradually decreases in the extension direction, which can reduce the overall volume and weight of the sound-absorbing unit 130 while ensuring the sound absorption effect. This can reduce the overall weight of the vehicle 1 and thus improve the fuel economy and operating efficiency of the vehicle 1.

[0029] According to one embodiment of the present invention, the sound insulation component 13 is constructed in multiple ways, and the multiple sound insulation components 13 are staggered on the body component 12, with the sound-absorbing units 130 in adjacent sound insulation components 13 being orthogonal to each other. The staggered arrangement of the multiple sound insulation components 13 on the body component 12 increases the coverage area and blocking effect of the sound insulation components 13 on the engine noise 11. Simultaneously, the orthogonal arrangement of the sound-absorbing units 130 in adjacent sound insulation components 13, i.e., the different arrangement directions of the sound-absorbing units 130 in adjacent sound insulation components 13, allows for noise absorption from multiple angles and directions, thereby more comprehensively capturing and consuming noise energy and significantly improving the noise reduction effect of the vehicle 1. Furthermore, the different arrangement directions of the sound-absorbing units 130 in adjacent sound insulation components 13 create a more complex sound-absorbing structure, causing more directional reflections when noise is transmitted to the sound insulation components 13, increasing the opportunity and time for sound to contact the sound-absorbing components 132, making the noise energy more effectively absorbed and consumed during propagation, further optimizing the noise absorption effect.

[0030] According to one embodiment of the present invention, the surface of the housing 131 is provided with a plurality of through holes spaced apart from each other. The design of the through holes allows sound waves to be directly transmitted to the sound-absorbing component 132, reducing the reflection of sound waves by the housing 131, increasing the direct contact area between the sound-absorbing component 132 and the sound waves, and improving the noise reduction effect.

[0031] According to one embodiment of the present invention, the body component 12 includes: a first side plate 121, a second side plate 122, and a connecting plate 123. The first side plate 121 and the second side plate 122 are respectively connected to the vehicle frame, and the first side plate 121 and the second side plate 122 are spaced apart on both sides of the engine 11 in the vehicle width direction. The connecting plate 123 is connected to the first side plate 121 and the second side plate 122 respectively. At least one of the first side plate 121, the second side plate 122, and the connecting plate 123 is provided with a sound insulation component 13. Figure 2 As shown, the main body 12 is provided with a first side plate 121 and a second side plate 122. The first side plate 121 and the second side plate 122 are respectively connected to two longitudinal beams on the frame. The connecting plate 123 connects the first side plate 121 and the second side plate 122 to each other. The arrangement of the first side plate 121, the second side plate 122 and the connecting plate 123 makes the entire main body 12 surround at least part of the outer periphery (side and bottom) of the engine 11. At this time, the sound insulation component 13 is provided on the first side plate 121, the second side plate 122 and the connecting plate 123, which can effectively absorb the noise transmitted from the side and bottom of the engine 11, thereby improving the sound insulation and noise reduction effect of the entire vehicle 1.

[0032] In some embodiments, the sound insulation component 13 can be installed on one or more of the first side plate 121, the second side plate 122, and the connecting plate 123 according to the actual needs of the engine 11, thus providing greater flexibility.

[0033] According to one embodiment of the present invention, the sound insulation component 13 includes: a first sound insulation component 134 and a second sound insulation component 135. Multiple first sound insulation components 134 are configured, arranged in multiple rows and columns on the first side plate 121 and / or the second side plate 122. A second sound insulation component 135 is disposed between two adjacent first sound insulation components 134 in each column, and between two adjacent first sound insulation components 134 in each row. Figure 2 As shown, sound insulation components 13 can be disposed on the first side panel 121 and the second side panel 122 to absorb noise transmitted from the side by the engine 11. The sound insulation components 13 include first sound insulation components 134 and second sound insulation components 135. In arrangement, multiple first sound insulation components 134 can be arranged in multiple rows and columns on the first side panel 121 and / or the second side panel 122, with a second sound insulation component 135 disposed between each pair of adjacent first sound insulation components 134 in each row and column, thereby making the sound-absorbing units 130 within adjacent sound insulation components 13 orthogonal. This dense and orderly layout of the sound insulation components 13 can absorb and isolate engine noise from multiple directions and angles, significantly improving all-around noise reduction capabilities. The orderly arrangement of multiple sound insulation components 13 on the side panels not only improves noise reduction performance but also enhances the structural strength of the main body component 12. The interaction between the sound insulation components 13 and the main body component 12 helps to disperse and absorb vibrations and stresses generated during engine 11 operation, thereby enhancing the structural stability of the entire vehicle 1.

[0034] According to one embodiment of this utility model, the length of the sound-absorbing component 132 in the extending direction is L, and the distance between the sound-absorbing component 132 and the main body component 12 is d, satisfying: 0.2≤d / L≤0.25. By specifying that the ratio of the length L of the sound-absorbing component 132 in the extending direction to the distance d between the sound-absorbing component 132 and the main body component 12 satisfies 0.2≤d / L≤0.25, it can be ensured that the sound-absorbing component 132 performs optimally in a limited space. The value of d / L in the range of 0.2~0.25 ensures that the sound-absorbing component 132 has sufficient length to effectively absorb noise, while also considering a reasonable distance between the sound-absorbing component 132 and the main body component 12, avoiding a decrease in sound absorption efficiency or waste of space due to excessively close or far distances.

[0035] In some embodiments, L can be 50mm, 55mm, or 60mm, and d can be 10mm or 15mm.

[0036] According to one embodiment of this utility model, the sound-absorbing component 132 is glass wool. As a porous sound-absorbing material, glass wool has excellent sound absorption performance. Using it as the sound-absorbing component 132 in the vehicle 1 can effectively absorb the noise generated by the engine 11, significantly reducing the noise level and improving the comfort of the user environment. Moreover, glass wool is lightweight, not adding excessive weight to the vehicle 1, which helps maintain the overall lightweight design of the vehicle 1. At the same time, glass wool has a stable structure, maintaining its sound absorption performance during engine 11 operation and is not easily deformed or damaged by vibration or temperature changes.

[0037] In some embodiments, the housing 131 may be constructed of metal.

[0038] In some embodiments, there are cavities (gap) between the sound-absorbing element 132 and the housing 131 and the body 12. Since the sound-absorbing element 132 is made of glass wool, it has a low acoustic impedance, while the housing 131 and the body 12 are rigid and have very high acoustic impedance. When sound encounters interfaces with different acoustic impedances during propagation, it will be reflected. If the sound-absorbing element 132 is directly attached to the housing 131 or the body 12, there will be a huge change in acoustic impedance between the wedge material and the rigid wall. This change will cause a considerable portion of the sound wave energy to be reflected back at the body 12 or the housing 131, thereby reducing the sound absorption effect. The cavity can be simply understood as an air layer that acts as a transition layer between the wedge and the body 12 or the housing 131.
