[0030] Reference below Figure 1-Figure 5 The acoustic package fixing structure 100 according to the embodiment of the present invention is described.

[0031] Reference Figure 1 and Figure 2 According to an embodiment of the present invention, an acoustic package fixing structure 100 includes: a protruding member 10 and a buckling member 20 .

[0032] The protruding member 10 is used to connect the noise source component 200. The buckle 20 is provided with an avoidance hole 21, and the protruding member 10 is inserted into the avoidance hole 21; wherein the buckle 20 has a first clamping portion 22 and a second clamping portion 23, the first clamping portion 22 extends in a direction away from the noise source component 200 toward the buckle 20, and the second clamping portion 23 extends in a direction toward the noise source component 200, and the first clamping portion 22 and the second clamping portion 23 clamp the protruding member 10 to position the acoustic package 300 between the buckle 20 and the noise source component 200 at the noise source component 200.

[0033] The acoustic package 300 is a component used for sound insulation and heat insulation on the vehicle. The acoustic package 300 is used to reduce the noise and vibration from the interior of the vehicle, improve the riding comfort, and improve the acoustic environment in the vehicle. The acoustic package 300 can be composed of multiple layers of materials, including sound absorbing materials (such as foam or fiber materials), sound insulation films (such as damping materials) and heat insulation materials. These materials can effectively absorb and prevent the propagation of sound waves, reduce noise from the engine, vehicle driving, wind noise, etc., and can also reduce vibration from the road surface and noise from mechanical parts inside the vehicle.

[0034] The protrusion 10 is disposed on the noise source component 200. The protrusion 10 may be integrally formed on the noise source component 200, or may be fixed to the noise source component 200 by a connecting component, such as a snap connection, a threaded connection, etc. Specifically, the noise source component 200 is a component that generates noise, such as an electric drive assembly, a compressor, a water pump, etc. The acoustic package fixing structure 100 is used to position the acoustic package 300 on the noise source component 200 to block the noise.

[0035] In the related technologies, electric vehicles are developing rapidly, and consumers have higher and higher requirements for the NVH (Noise, Vibration, and Harshness) performance of electric vehicles. Using acoustic packages to block noise has become a common solution for major automobile manufacturers. However, due to the harsh environment, accompanied by vibration, stone impact, mud and water erosion, etc., the fixing effect of existing acoustic packages is average, and they are prone to abnormal detachment during vehicle driving.

[0036] In the embodiment of the utility model, a first clamping portion 22 and a second clamping portion 23 are provided on the buckle 20, and the first clamping portion 22 and the second clamping portion 23 extend in the directions of both sides of the buckle 20 respectively, and the first clamping portion 22 extends in the direction of the buckle 20 away from the noise source component 200, and the first clamping portion 22 stops the protruding piece 10, thereby reducing the probability of the protruding piece 10 being separated from the buckle 20, and the second clamping portion 23 extends in the direction of the noise source component 200, and the second clamping portion 23 stops the protruding piece 10, thereby reducing the probability of the protruding piece 10 being further inserted into the buckle 20, and the protruding piece 10 is stationary relative to the buckle 20, so that the buckle 20 is prevented from shaking relative to the protruding piece 10 during the vibration of the vehicle, so that the acoustic package 300 is stabilized on the noise source component 200, thereby improving the reliability of the acoustic package fixing structure 100, thereby reducing the probability of abnormal detachment of the acoustic package 300.

[0037] For example, refer to Figure 2The protruding piece 10 extends in left and right directions, the snap member 20, the acoustic package 300 and the noise source component 200 are arranged from right to left in sequence, the first snap-fit ​​portion 22 extends obliquely to the right and is snap-fitted to the protruding piece 10, so that the protruding piece 10 cannot move to the left relative to the snap-fit ​​portion 20, the second snap-fit ​​portion 23 is snap-fitted to the protruding piece 10 obliquely to the left, so that the protruding piece 10 cannot move to the right relative to the snap-fit ​​portion 20, the snap-fit ​​portion 20 is stationary relative to the noise source component 200, the snap-fit ​​portion 20 is buckled on one side of the acoustic package 300, the acoustic package 300 is fixed on the noise source component 200, and the noise is blocked.

[0038] Specifically, the protruding member 10 is inserted into the avoidance hole 21 on the buckle member 20, and the first clamping portion 22 and the second clamping portion 23 can be arranged on opposite sides of the avoidance hole 21. Figure 2 The first clamping portion 22 and the second clamping portion 23 are arranged on the upper and lower sides of the avoidance hole 21, the first clamping portion 22 and the second clamping portion 23 directly stop the protruding piece 10, and the protruding piece 10 has no contact with the inner wall of the avoidance hole 21; the first clamping portion 22 and the second clamping portion 23 can also be arranged on the same side of the avoidance hole 21, the first clamping portion 22 and the second clamping portion 23 stop on the same side of the protruding piece 10, and the other side of the avoidance hole 21 stops on the opposite side of the protruding piece 10, so that the buckle 20 is stationary relative to the protruding piece 10.

[0039] According to the acoustic package fixing structure 100 of the embodiment of the utility model, by providing the first clamping portion 22 and the second clamping portion 23 on the snap member 20, the first clamping portion 22 extends in the direction of the snap member 20 away from the noise source component 200, and the second clamping portion 23 extends in the direction of the noise source component 200, the first clamping portion 22 and the second clamping portion 23 clamp the protrusion 10, thereby reducing the probability of the protrusion 10 detaching from the snap member 20, and reducing the probability of the protrusion 10 further inserting into the snap member 20, the protrusion 10 is stationary relative to the snap member, so that the acoustic package 300 is stabilized on the noise source component 200, thereby improving the reliability of the acoustic package fixing structure 100, thereby reducing the probability of abnormal detachment of the acoustic package 300.

[0040] Reference Figure 3 In some embodiments, the length of the second clamping portion 23 is smaller than the length of the first clamping portion 22 .

[0041] The second clamping portion 23 is shorter than the first clamping portion 22 , and the second clamping portion 23 extends toward the noise source component 200 , so as to facilitate the installation of the buckle 20 onto the protruding member 10 .

[0042] In the above solution, the second clamping portion 23 is relatively short and extends toward the noise source component 200 . The shorter length allows the second clamping portion 23 to avoid the protrusion 10 , thereby making it easier for the buckle 20 to be installed on the protrusion 10 .

[0043] In some embodiments, the buckle 20 includes: a buckle body 24, a avoidance hole 21 is provided in the buckle body 24, and an angle θ1 is provided between the first clamping portion 22 and the buckle body 24, 10°≤θ1≤45°.

[0044] The first clamping portion 22 is tilted on the buckle body 24 , and the angle θ1 between the first clamping portion 22 and the buckle body 24 is within a certain range, that is, the tilt angle of the first clamping portion 22 relative to the buckle body 24 is within a certain range.

[0045] In the related art, the angle θ1 between the first clamping portion 22 and the buckle body is greater than 45°. The larger angle makes the interference fit between the first clamping portion and the protruding part smaller, which may cause instability of the protruding part. Alternatively, the angle θ1 between the first clamping portion and the buckle body is less than 10°. The smaller angle makes the contact area between the first clamping portion and the protruding part smaller, which may cause instability of the protruding part.

[0046] In the above scheme, by setting the angle θ1 between the first clamping portion 22 and the buckle body portion 24 in the range of 10° to 45°, the first clamping portion 22 can better contact the protruding member 10, so that the first clamping portion 22 can be better clamped on the protruding member 10, thereby improving stability.

[0047] For example, the angle θ1 between the first clamping portion 22 and the buckle main body 24 is 10°; or, the angle θ1 between the first clamping portion 22 and the buckle main body 24 is 15°; or, the angle θ1 between the first clamping portion 22 and the buckle main body 24 is 20°; or, the angle θ1 between the first clamping portion 22 and the buckle main body 24 is 25°; or, the angle θ1 between the first clamping portion 22 and the buckle main body 24 is 30°; or, the angle θ1 between the first clamping portion 22 and the buckle main body 24 is 35°; or, the angle θ1 between the first clamping portion 22 and the buckle main body 24 is 40°; or, the angle θ1 between the first clamping portion 22 and the buckle main body 24 is 45°.

[0048] In some embodiments, an angle θ2 is defined between the second engaging portion 23 and the buckle body portion 24, and the angle θ2 is 10°≤θ2≤45°.

[0049] The second clamping portion 23 is tilted on the buckle body 24 , and the angle θ2 between the second clamping portion 23 and the buckle body 24 is within a certain range, that is, the tilt angle of the second clamping portion 23 relative to the buckle body 24 is within a certain range.

[0050] In the related art, the angle θ2 between the second clamping portion and the buckle main body is greater than 45°. The larger angle makes the interference fit between the second clamping portion and the protruding part smaller, which may cause instability of the protruding part. Alternatively, the angle θ2 between the second clamping portion and the buckle main body is less than 10°. The smaller angle makes the contact area between the second clamping portion and the protruding part smaller, which may cause instability of the protruding part.

[0051] In the above scheme, by setting the angle θ2 between the second clamping portion 23 and the buckle main body 24 in the range of 10° to 45°, the second clamping portion 23 can better contact the protruding member 10, so that the second clamping portion 23 is better clamped on the protruding member 10, thereby improving stability.

[0052] For example, the angle θ2 between the second clamping portion 23 and the buckle main body 24 is 10°; or, the angle θ2 between the second clamping portion 23 and the buckle main body 24 is 15°; or, the angle θ2 between the second clamping portion 23 and the buckle main body 24 is 20°; or, the angle θ2 between the second clamping portion 23 and the buckle main body 24 is 25°; or, the angle θ2 between the second clamping portion 23 and the buckle main body 24 is 30°; or, the angle θ2 between the second clamping portion 23 and the buckle main body 24 is 35°; or, the angle θ2 between the second clamping portion 23 and the buckle main body 24 is 40°; or, the angle θ2 between the second clamping portion 23 and the buckle main body 24 is 45°.

[0053] Reference Figure 3 In some embodiments, the buckle 20 includes: a buckle body 24, an avoidance hole 21 is provided in the buckle body 24, an angle θ1 is provided between the first buckle portion 22 and the buckle body 24, 10°≤θ1≤45°, and an angle θ2 is provided between the second buckle portion 23 and the buckle body 24, 10°≤θ2≤45°.

[0054] For example, the angle θ1 between the first clamping portion 22 and the buckle body 24 is 25°, and the angle θ2 between the second clamping portion 23 and the buckle body 24 is 15°. The smaller θ2 makes the assembly of the buckle 20 and the protruding member 10 smoother without any clamping resistance.

[0055] In some specific embodiments, the length of the first clamping portion 22 is 4 mm, and the length of the second clamping portion 23 is 2 mm.

[0056] In some specific embodiments, the first clamping portion 22 is larger than 1 mm after clamping the protruding member 10, and the second clamping portion 23 is larger than 1 mm after clamping the protruding member 10, thereby improving stability.

[0057] Reference Figure 4 , Figure 5 In some embodiments, the buckle 20 includes: a buckle body 24 , the avoidance hole 21 is provided in the buckle body 24 , and the width of the first clamping portion 22 gradually decreases in a direction away from the buckle body 24 .

[0058] Among them, the first clamping portion 22 is arranged on the buckle main body 24, and the first clamping portion 22 extends in the direction away from the buckle main body 24. In the extending direction of the first clamping portion 22, the width of the first clamping portion 22 gradually decreases. Compared with the part close to the buckle main body 24, the part of the first clamping portion 22 away from the buckle main body 24 is sharper, and the part of the first clamping portion 22 away from the buckle main body 24 clamps the protrusion 10.

[0059] In the above scheme, the width of the first clamping portion 22 is gradually reduced in the extension direction of the first clamping portion 22, so that the contact portion between the first clamping portion 22 and the protrusion 10 is sharper, making the clamping of the first clamping portion 22 more stable and improving reliability.

[0060] Specifically, the first clamping portion 22 may be configured to be a trapezoid, where the first clamping portion 22 is narrow at the top and wide at the bottom; or, the edge of the first clamping portion 22 may be configured to be an arc.

[0061] Reference Figure 4 In some embodiments, there are multiple first clamping portions 22 , wherein at least two adjacent first clamping portions 22 are connected via a middle portion 221 .

[0062] Among them, two partially adjacent first clip parts 22 may be connected via the middle part 221, for example, if there are eight first clip parts 22, two of the eight first clip parts 22 are connected via the middle part 221, or all of the first clip parts 22 may be connected via the middle part 221, for example, if there are eight first clip parts 22, two adjacent first clip parts 22 are connected via the middle part 221, and the eight first clip parts 22 are combined into four separate components.

[0063] In the above solution, two adjacent first clamping portions 22 are connected via the middle portion 221 , and the two first clamping portions 22 connected via the middle portion 221 are combined into an integral piece, thereby improving strength and stability.

[0064] Reference Figure 4 , Figure 5In some embodiments, the width of the second clamping portion 23 away from the buckle body 24 is equal to the width of the second clamping portion 23 close to the buckle body 24 .

[0065] In the extending direction of the second clamping portion 23 , the widths of the various parts of the second clamping portion 23 are the same, and the second clamping portion 23 is flush with each other from top to bottom.

[0066] In the above solution, by providing the second clamping portion 23 that is flush with the upper and lower parts, the length of the second clamping portion 23 is short, and the wider second clamping portion 23 has a larger contact area with the protruding member 10, thereby improving the clamping stability.

[0067] In some embodiments, the first clamping portion 22 is disposed on the inner wall of the avoidance hole 21 to clamp the protruding member 10 when the protruding member 10 is inserted into the avoidance hole 21 .

[0068] A first clamping portion 22 extends from the inner wall of the avoidance hole 21 , and the protruding member 10 directly contacts the first clamping portion 22 when passing through the avoidance hole 21 .

[0069] In the above solution, by arranging the first clamping portion 22 on the inner wall of the avoidance hole 21, the first clamping portion 22 directly contacts the protruding member 10, and the contact between the first clamping portion 22 and the protruding member 10 is more complete, thereby improving stability.

[0070] In other embodiments, the second clamping portion 23 is disposed on the inner wall of the avoidance hole 21 to clamp the protruding member 10 when the protruding member 10 is inserted into the avoidance hole 21 .

[0071] The second clamping portion 23 extends from the inner wall of the avoidance hole 21 , and the protruding member 10 directly contacts the second clamping portion 23 when passing through the avoidance hole 21 .

[0094] The vehicle according to the embodiment of the present utility model includes: a noise source component 200 , an acoustic package 300 and an acoustic package fixing structure 100 .

[0095] The noise source component 200 includes one or more of an electric drive assembly, a compressor, and a water pump. The acoustic package 300 is provided with a through hole. The acoustic package fixing structure 100 is constructed as the above-mentioned acoustic package fixing structure 100, the protrusion 10 is passed through the through hole, and the buckle 20 is provided on the side of the acoustic package 300 away from the noise source component 200, so as to position the acoustic package 300 on the noise source component 200.

[0096] Among them, the noise source component 200 can be an electric drive assembly, a compressor, or a water pump, or the noise source component 200 includes an electric drive assembly and a compressor, or the noise source component 200 includes an electric drive assembly and a water pump, or the noise source component 200 includes a compressor and a water pump; or the noise source component 200 includes an electric drive assembly, a compressor, and a water pump.

[0097] The snap-fit ​​member 20 is located on the side of the acoustic package 300 away from the noise source component 200 , and the snap-fit ​​member 20 cooperates with the protrusion 10 on the noise source component 200 to fix the acoustic package 300 on the noise source component 200 , thereby isolating the noise by using the acoustic package 300 .

[0098] According to the vehicle of the embodiment of the utility model, by arranging the first clamping portion 22 and the second clamping portion 23 on the snap member 20, the first clamping portion 22 extends in the direction of the snap member 20 away from the noise source component 200, and the second clamping portion 23 extends in the direction of the noise source component 200. The first clamping portion 22 and the second clamping portion 23 clamp the protrusion 10, thereby reducing the probability of the protrusion 10 being separated from the snap member 20 and the probability of the protrusion 10 being further inserted into the snap member 20. The protrusion 10 is stationary relative to the snap member, so that the acoustic package 300 is stabilized on the noise source component 200, thereby improving the reliability of the acoustic package fixing structure 100, thereby reducing the probability of abnormal detachment of the acoustic package 300.

[0099] Specifically, the acoustic package 300 is first combined with the protrusion 10 through the through hole, and then the snap member 20 is pressed vertically to the bottom. The first snap portion 22 and the second snap portion 23 will be located at the bottom of the protrusion 10. The snap member 20 and the protrusion 10 are snapped together to form a reaction force to prevent the snap member 20 from accidentally falling off.
