[0028] The following refers to Figure 1 - Figure 2 Describe the isolation structure 100 of the hood cable according to the embodiment of the present invention.
[0029] Refer to Figure 1 , Figure 2, An isolation structure 100 for a hood cable according to an embodiment of the present utility model includes: a body sheet metal part 10, a sound insulation layer 20, and a rubber sleeve 30.
[0030] The body sheet metal part 10 isolates a passenger compartment space 11 and an engine compartment space 12. An installation hole 13 communicating the passenger compartment space 11 and the engine compartment space 12 is formed on the body sheet metal part 10. The sound insulation layer 20 is disposed on the body sheet metal part 10. The sound insulation layer 20 is provided with an avoidance hole 21, and the avoidance hole 21 corresponds to the installation hole 13. The rubber sleeve 30 is provided with a wire hole for passing through the hood cable 200. One end of the hood cable 200 is connected to a handle in the passenger compartment space 11, and the other end is connected to a hood locking structure in the engine compartment space 12 to control the opening of the hood. The rubber sleeve 30 is inserted into the installation hole 13 and partially abuts against the sound insulation layer 20.
[0031] Among them, the body sheet metal part 10 is a part of the vehicle body. The vehicle body has a passenger compartment space 11 and an engine compartment space 12. The passengers are located in the passenger compartment space 11, and the engine compartment space 12 is used for placing components such as engines. The body sheet metal part 10 is located between the passenger compartment space 11 and the engine compartment space 12, and the body sheet metal part 10 isolates the passenger compartment space 11 and the engine compartment space 12.
[0032] The components in the engine compartment space 12 generate noise during operation. A sound insulation layer 20 is provided on the body sheet metal part 10. For example, the sound insulation layer 20 is configured as a sound insulation pad to effectively isolate noise, such as the noise generated by the engine during operation.
[0033] The engine compartment space 12 usually has an opening. The hood is movably disposed at the opening. A hood locking structure is provided in the engine compartment space 12. The hood locking structure is adapted to connect to the hood to position the hood at the opening. The hood locking structure can also disconnect from the hood, so that the hood can move freely. The specific structures of the hood locking structure and the hood are prior arts and will not be elaborated here. Part of the hood cable 200 is located in the passenger compartment space 11, and the other part is located in the engine compartment space 12. A handle is provided in the passenger compartment space 11. One end of the hood cable 200 is connected to the handle, and the other end is connected to the hood locking structure. The hood cable 200 is a flexible member. The passengers operate the handle to control the hood locking structure and indirectly control the hood.
[0034] In the related art, the opening of the hoods of various vehicle models needs to be achieved by pulling the handle. The handle is connected to the hood cable and passes through the body sheet metal part to be connected to the hood locking structure. An installation hole is provided on the body sheet metal part for avoiding the hood cable. In order to isolate noise, a sound insulation layer is attached to the body sheet metal part, and a rubber sleeve is provided in the installation hole. However, the noise in the engine compartment space can still be conducted into the passenger compartment space, and the noise in the passenger compartment space is relatively large.
[0035] After a large number of studies by the inventor, it is found that the gap between the sound insulation layer and the rubber sleeve is a sound insulation dead angle. For the convenience of installation, the sound insulation layer is usually provided with a relief hole, and the diameter of the relief hole is larger than the diameter of the rubber sleeve, resulting in part of the body sheet metal not being covered. The noise in the engine compartment leaks into the passenger space through the uncovered area, resulting in a large amount of noise.
[0036] In the embodiment of the present utility model, by providing the rubber sleeve 30 to abut against the sound insulation layer 20, no gap will be formed between the rubber sleeve 30 and the sound insulation layer 20, and the noise in the engine compartment space 12 cannot leak into the passenger space 11 through the gap between the rubber sleeve 30 and the sound insulation layer 20, thereby improving the noise problem.
[0037] Specifically, the rubber sleeve 30 can be partially extended in the direction of the sound insulation layer 20, and the extended part of the rubber sleeve 30 abuts against the sound insulation layer 20; the rubber sleeve 30 can also be provided with a notch, the volume of the rubber sleeve 30 is large, and the notch is directly sleeved on the sound insulation layer 20.
[0038] According to the isolation structure 100 of the hood cable in the embodiment of the present utility model, by providing the rubber sleeve 30 to abut against the sound insulation layer 20, the rubber sleeve 30 is in full contact with the sound insulation layer 20, and the noise in the engine compartment space 12 cannot leak into the passenger space 11 through the gap between the rubber sleeve 30 and the sound insulation layer 20, thereby improving the noise problem.
[0039] Refer to Figure 1 、 Figure 2 In some embodiments, the rubber sleeve 30 includes: a main body portion 31 and an extension portion 32.
[0040] The extension portion 32 is provided on the main body portion 31 and extends away from the main body portion 31, and at least a part of the extension portion 32 abuts against the sound insulation layer 20.
[0041] Among them, the wire hole is provided on the main body portion 31, the hood cable 200 passes through the main body portion 31, the extension portion 32 is provided on the main body portion 31 and extends away from the main body portion 31, the extension portion 32 extends from the main body portion 31 towards the sound insulation layer 20, and part of the structure on the extension portion 32 abuts against the sound insulation layer 20.
[0042] In the above solution, by providing the extension portion 32 on the main body portion 31 and using the extension portion 32 to abut against the sound insulation layer 20, no gap will be formed between the rubber sleeve 30 and the sound insulation layer 20, and the noise in the engine compartment space 12 cannot leak into the passenger space 11 through the gap between the rubber sleeve 30 and the sound insulation layer 20, thereby improving the noise problem.
[0043] Specifically, the extension portion 32 is an independently protruding part on the main body portion 31, and the whole presents a ring shape, so as to better contact the sound insulation layer 20.
[0044] Refer to Figure 1 、 Figure 2, in some embodiments, there are multiple sound insulation layers 20. The multiple sound insulation layers 20 include a first sound insulation layer 22 and a second sound insulation layer 23. The first sound insulation layer 22 is disposed in the passenger compartment space 11, and the second sound insulation layer 23 is disposed in the engine compartment space 12. The extension portion 32 includes: a first extension portion 321 and a second extension portion 322.
[0045] The first extension portion 321 is disposed in the passenger compartment space 11, and the first extension portion 321 abuts against the first sound insulation layer 22. The second extension portion 322 is disposed in the engine compartment space 12, and the second extension portion 322 abuts against the second sound insulation layer 23.
[0046] Wherein, one side of the vehicle body sheet metal part 10 faces the passenger compartment space 11, and the opposite side faces the engine compartment space 12. There are multiple sound insulation layers 20. The multiple sound insulation layers 20 include a first sound insulation layer 22 and a second sound insulation layer 23. The first sound insulation layer 22 is disposed on the side of the vehicle body sheet metal part 10 facing the passenger compartment space 11, and the second sound insulation layer 23 is disposed on the side of the vehicle body sheet metal part 10 facing the engine compartment space 12. And the extension portion 32 includes: a first extension portion 321 and a second extension portion 322. The first extension portion 321 abuts against the first sound insulation layer 22, and the second extension portion 322 abuts against the second sound insulation layer 23.
[0047] In the above solution, by providing multiple sound insulation layers 20 and multiple extension portions 32, multi-layer noise reduction is achieved, thereby further improving the noise problem.
[0048] In some embodiments, the thickness of the second extension portion 322 is greater than the thickness of the first extension portion 321.
[0049] Wherein, the second extension portion 322 is disposed in the engine compartment space 12, the second extension portion 322 abuts against the second sound insulation layer 23, and the second extension portion 322 is thicker than the first extension portion 321. Different thickness objects have different effects on noises in different frequency bands. The thicknesses of the second extension portion 322 and the first extension portion 321 are different. The second extension portion 322 is for noises in one frequency band, while the first extension portion 321 is for noises in another frequency band.
[0050] In the above solution, by providing extension portions 32 with different thicknesses, respectively targeting noises in different frequency bands, the targeting is improved, and the noise problem is further improved.
[0051] Referring to Figure 1 、 Figure 2 , in some specific embodiments, the thickness of the first extension portion 321 is h1, and 1 mm ≤ h1 ≤ 1.5 mm.
[0052] Wherein, the thickness of the first extension portion 321 is in the range of 1 mm to 1.5 mm. The first extension portion 321 is located in the passenger compartment space 11, and the first extension portion 321 abuts against the first sound insulation layer 22 to isolate noise.
[0053] In the above solution, by setting the first extension portion 321 with a thickness of 1 mm to 1.5 mm, the first extension portion 321 improves the filtering effect on noise within a frequency band.
[0054] For example, the thickness h1 of the first extension portion 321 is 1 mm; or, the thickness h1 of the first extension portion 321 is 1.1 mm; or, the thickness h1 of the first extension portion 321 is 1.2 mm; or, the thickness h1 of the first extension portion 321 is 1.3 mm; or, the thickness h1 of the first extension portion 321 is 1.4 mm; or, the thickness h1 of the first extension portion 321 is 1.5 mm.
[0055] Refer to Figure 1 、 Figure 2 In some specific embodiments, the thickness of the second extension portion 322 is h2, and 1.5 mm < h2 ≤ 2 mm.
[0056] Wherein, the thickness of the second extension portion 322 is within the range of 1.5 mm to 2 mm. The second extension portion 322 is located within the cabin space 12, and the second extension portion 322 abuts against the second sound insulation layer 23 to isolate noise.
[0057] In the above solution, by setting the second extension portion 322 with a thickness of 1.5 mm to 2 mm, the second extension portion 322 improves the filtering effect on noise within another frequency band.
[0058] For example, the thickness h2 of the second extension portion 322 is 1.6 mm; or, the thickness h2 of the second extension portion 322 is 1.7 mm; or, the thickness h2 of the second extension portion 322 is 1.8 mm; or, the thickness h2 of the second extension portion 322 is 1.9 mm; or, the thickness h2 of the second extension portion 322 is 2 mm.
[0059] Refer to Figure 1 、 Figure 2 In some embodiments, the extension portion 32, the sound insulation layer 20 and the vehicle body sheet metal part 10 jointly define a sealed cavity 24.
[0060] Wherein, the extension portion 32 abuts against the sound insulation layer 20. The extension portion 32 separately isolates a space on one side of the sound insulation layer 20 and the vehicle body sheet metal part 10 to form the sealed cavity 24, thereby exerting a sound insulation effect.
[0061] In the above solution, by setting the extension portion 32, the sound insulation layer 20 and the vehicle body sheet metal part 10 to jointly define the sealed cavity 24, the sealed cavity 24 is used to attenuate noise, thereby improving the noise problem and enhancing the noise reduction effect.
[0062] Specifically, there are multiple sound insulation layers 20. The multiple sound insulation layers 20 include a first sound insulation layer 22 and a second sound insulation layer 23. The first sound insulation layer 22 is disposed in the passenger space 11, and the second sound insulation layer 23 is disposed in the cabin space 12. The extension portion 32 includes a first extension portion 321 and a second extension portion 322. The first extension portion 321 is disposed in the passenger space 11, and the first extension portion 321 abuts against the first sound insulation layer 22. The second extension portion 322 is disposed in the cabin space 12, and the second extension portion 322 abuts against the second sound insulation layer 23. A first sealed cavity 24 is formed between the first extension portion 321, the first sound insulation layer 22, and the body sheet metal part 10. A second sealed cavity 24 is formed between the second extension portion 322, the second sound insulation layer 23, and the body sheet metal part 10.
[0063] In some embodiments, the extension portion 32 has a first posture and a second posture. When the extension portion 32 is in the first posture, as shown in Figure 1 shown, the extension portion 32 abuts against the sound insulation layer 20. When the extension portion 32 is in the second posture, as shown in Figure 2 shown, the extension portion 32 is spaced apart from the sound insulation layer 20.
[0064] Among them, the extension portion 32 has a certain elasticity, and the extension portion 32 can be switched between the first posture and the second posture, which facilitates installation.
[0065] Specifically, the extension portion 32 is a leather cup structure, and the leather cup structure is integrally injection molded with the main body portion 31, which improves the convenience.
[0066] During installation, the leather cup structure on the passenger space 11 side unfolds in the backward direction. The diameter of the leather cup structure is smaller than the maximum diameter of the main body portion 31, which is convenient for installation. After being snapped in place, the leather cup structures on both sides are adjusted back to their original positions. The edge of the leather cup structure will press against the sound insulation layer 20, covering the part of the body sheet metal part 10 that was originally exposed. The leather cup structures on both sides press against the sound insulation layer 20, forming two sealed cavities 24 outside the body sheet metal part 10. When sound propagates, the sealed cavities 24 can play a role in sound attenuation, can further insulate sound while preventing leakage, and effectively improve the sound insulation performance of this area.
[0067] In some embodiments, a weakening cavity 311 is provided on the main body portion 31, and the weakening cavity 311 is spaced apart from both ends of the main body portion 31 in the length direction.
[0068] Among them, the main body portion 31 has an end position. The weakening cavity 311 is spaced apart from both ends of the main body portion 31, and the weakening cavity 311 is disposed at the middle position of the main body portion 31. When the hood cable 200 passes through the main body portion 31, the rubber sleeve 30 compresses and stretches, which facilitates the installation of the hood cable 200.
[0069] In the above solution, by providing a weakening cavity 311 on the main body 31, the deformation of the rubber sleeve 30 is facilitated by the weakening cavity 311. The rubber sleeve 30 is compressed, stretched, and the hood cable 200 is installed in place, improving convenience.
[0070] Specifically, there are multiple weakening cavities 311, and the multiple weakening cavities 311 are sequentially arranged along the length direction of the main body 31, further improving the weakening effect and making the rubber sleeve 30 more easily deformable. For example, there are two weakening cavities 311, and the two weakening cavities 311 are sequentially arranged along the length direction of the main body 31, facilitating use.
[0071] Refer to Figure 2 As shown, in some embodiments, the main body 31 is provided with an installation groove 312, and the opposite groove walls of the installation groove 312 abut against the opposite side surfaces of the vehicle body sheet metal part 10.
[0072] Among them, the installation groove 312 is located on the main body 31. When the main body 31 passes through the installation hole 13, the vehicle body sheet metal part 10 is inserted into the installation groove 312, and the opposite groove walls of the installation groove 312 abut against the opposite side surfaces of the vehicle body sheet metal part 10. The rubber sleeve 30 has a certain elasticity, and the vehicle body sheet metal part 10 abuts against the opposite groove walls of the installation groove 312.
[0073] In the above solution, by opening the installation groove 312 on the main body 31, the vehicle body sheet metal part 10 is clamped by the installation groove 312, thereby improving the sealing performance.
[0074] The vehicle according to an embodiment of the present invention includes the isolation structure 100 of the hood cable as described above.
[0075] In the vehicle according to an embodiment of the present invention, by providing the rubber sleeve 30 to abut against the sound insulation layer 20, the rubber sleeve 30 is in full contact with the sound insulation layer 20, and the noise in the engine compartment space 12 cannot leak into the passenger space 11 through the gap between the rubber sleeve 30 and the sound insulation layer 20, thereby improving the noise problem.
