[0031] The present utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0032] As Figure 3 shown, a vehicle according to an embodiment of the present utility model includes a roof mounting beam 110 and a radar component 120.

[0033] Furthermore, in combination with Figure 1 and Figure 2, the vehicle further includes a mounting plate 130. The mounting plate 130 is connected to the side of the roof mounting beam 110 where the radar assembly 120 is provided, and the mounting plate 130 is used to shield the radar assembly 120, so as to play a role in protecting the radar assembly 120, reducing the risk of damage to the radar assembly 120, and the mounting plate 130 can play a role in decorating the vehicle, preventing the radar assembly 120 from being exposed, which is beneficial to improving the aesthetics of the vehicle.

[0034] A first noise reduction layer 131 is provided on the surface of the mounting plate 130 opposite to the roof mounting beam 110. The first noise reduction layer 131 is arranged between the mounting plate 130 and the roof mounting beam 110.

[0035] Since the position where the radar is provided on the vehicle protrudes compared with other positions of the vehicle, when the vehicle is driving at high speed, when the airflow passes through the radar, it will cause the airflow field to be disordered, resulting in the formation of high-speed wind noise. In the related art, the top cover exterior panel directly covers the radar, and no structure with a sound absorption function is provided, resulting in a large amount of noise transmitted into the vehicle, which affects the driving and riding experience of users.

[0036] In this application, by providing the first noise reduction layer 131 on the mounting plate 130, the first noise reduction layer 131 can play a role in sound absorption to consume the energy excited on the mounting plate 130, improve the sound absorption performance of the mounting plate 130, reduce the noise transmitted into the vehicle, and is beneficial to improving the driving and riding experience of users.

[0037] Refer to Figure 3 , in some embodiments of the present utility model, the radar assembly 120 includes a radar body 121 and a second noise reduction layer 122. The second noise reduction layer 122 is provided on the radar body 121. The radar body 121 is used to detect obstacles. By providing the second noise reduction layer 122 on the radar body 121, the second noise reduction layer 122 has a sound absorption function to absorb the noise transmitted to the radar body 121, so as to be beneficial to further reducing the noise transmitted into the vehicle, and the second noise reduction layer 122 can play a vibration damping effect, reducing the interference generated by vibration on the radar body 121, so as to be beneficial to reducing the risk of damage to the radar body 121.

[0038] The second noise reduction layer 122 is provided to cover at least part of the radar body 121. For example, the second noise reduction layer 122 can be provided on the surface of the radar body 121 opposite to the mounting plate 130. And in the direction where the mounting plate 130 extends towards the roof mounting beam 110, the orthographic projection surface of the second noise reduction layer 122 can completely coincide with the orthographic projection surface of the surface of the radar body 121 opposite to the mounting plate 130, that is, the second noise reduction layer 122 can completely cover the surface of the radar body 121 opposite to the mounting plate 130 to improve the sound absorption and vibration damping effect of the second noise reduction layer 122; or the second noise reduction layer 122 can be provided to cover multiple surfaces of the radar body 121 to further improve the sound absorption and vibration damping effect of the second noise reduction layer 122.

[0039] It can be understood that the specific setting manner of the second noise reduction layer 122 can be determined according to actual production requirements and is not specifically limited herein.

[0040] As Figure 3 shown, in some embodiments of the present utility model, the second noise reduction layer 122 is clamped between the first noise reduction layer 131 and the radar body 121 to facilitate the arrangement of the second noise reduction layer 122. And when the noise passes through the first noise reduction layer 131, the second noise reduction layer 122 can further absorb the noise to reduce the noise transmitted into the vehicle, improve the noise reduction effect, and the second noise reduction layer 122 can reduce the interference of vibration on the radar body 121.

[0041] The second noise reduction layer 122 is clamped between the roof mounting beam 110 and the radar body 121, that is, the second noise reduction layer 122 is provided on the surface of the radar body 121 opposite to the roof mounting beam 110. The second noise reduction layer 122 can absorb the noise transmitted to the roof mounting beam 110 to reduce the noise transmitted into the vehicle, and can reduce the interference of vibration on the radar body 121.

[0042] Optionally, the second noise reduction layer 122 can be separately provided on the surface of the radar body 121 opposite to the first noise reduction layer 131, or the second noise reduction layer 122 can be separately provided on the surface of the radar body 121 opposite to the roof mounting beam 110, which is beneficial to reducing the production cost of the vehicle and simplifying the assembly steps of the vehicle; the second noise reduction layer 122 can be provided on both the side of the radar body 121 opposite to the first noise reduction layer 131 and the side of the radar body 121 opposite to the roof mounting beam 110 to improve the sound absorption and vibration damping effect.

[0043] It can be understood that the specific setting manner of the second noise reduction layer 122 can be determined according to actual production requirements and is not specifically limited herein.

[0044] In some embodiments of the present utility model, the second noise reduction layer 122 located between the radar body 121 and the roof mounting beam 110 is provided with an avoidance hole through which a connecting member can pass, and the connecting member is used to fixedly connect the radar body 121 and the roof mounting beam 110.

[0045] The radar body 121 can be fixedly connected to the roof mounting beam 110 through a connecting member (such as a bolt, etc.). By providing an avoidance hole in the second noise reduction layer 122 located between the radar body 121 and the roof mounting beam 110, it is convenient for the connecting member to pass through the second noise reduction layer 122, thereby facilitating the connecting member to fixedly connect the radar body 121 and the roof mounting beam 110, and is beneficial to ensuring the effect of the rigid connection between the radar body 121 and the roof mounting beam 110, thus being beneficial to improving the assembly reliability of the radar body 121.

[0046] In some embodiments of the present utility model, the second noise reduction layer 122 is configured as a PU foam layer.

[0047] It should be noted that PU is a polyurethane material, which is the abbreviation of polyaminoester, and its full English name is polyurethan.

[0048] The PU foam layer has good sound insulation performance, which is beneficial to improving the noise reduction effect of the second noise reduction layer 122. Moreover, the cost of the PU foam layer is low and the material is light, which is beneficial to reducing the material cost required for producing the second noise reduction layer 122 and is beneficial to achieving weight reduction and cost reduction of the vehicle.

[0049] And the second noise reduction layer 122 can be a low-density PU foam layer to further improve the sound absorption effect of the second noise reduction layer 122 and reduce the interference of vibration on the radar body 121.

[0050] As Figure 3 shown, in some embodiments of the present utility model, the roof mounting beam 110 includes: a front crossbeam upper plate 111, and the front crossbeam upper plate 111 is used to mount the radar assembly 120 and the mounting plate 130.

[0051] For example, the radar body 121 can be rigidly connected to the front crossbeam upper plate 111 through a connecting member (such as a bolt, etc.), which is beneficial to improving the assembly reliability of the radar assembly 120. And the second noise reduction layer 122 can be clamped between the radar body 121 and the front crossbeam upper plate 111 to facilitate the fixing of the second noise reduction layer 122. When the second noise reduction layer 122 is provided on the surface of the radar body 121 opposite to the mounting plate 130, the second noise reduction layer 122 located between the radar body 121 and the mounting plate 130 can be bonded to the surface of the radar body 121 and the mounting plate 130 opposite to each other to facilitate the installation of the radar assembly 120 onto the front crossbeam upper plate 111.

[0052] The mounting plate 130 can be installed on the front crossbeam upper plate 111 by means of threaded connectors (such as screws, bolts, etc.), which is beneficial to improving the assembly convenience of the mounting plate 130. It can be understood that the specific assembly method of the mounting plate 130 can be determined according to actual production requirements and is not specifically limited here.

[0053] like Figure 3 As shown, the roof mounting beam 110 further includes a front cross beam lower plate 112 , which is connected to a side of the front cross beam upper plate 111 away from the radar assembly 120 and the mounting plate 130 to prevent the front cross beam lower plate 112 from interfering with the assembly of the radar assembly 120 and the mounting plate 130 .

[0054] Further, refer to Figure 3 The roof mounting beam 110 further includes a noise reduction component 113 , and the noise reduction component 113 is filled and arranged between the front cross beam upper plate 111 and the front cross beam lower plate 112 .

[0055] An installation space can be defined between the front cross beam lower plate 112 and the front cross beam upper plate 111 for filling the noise reduction component 113. The noise reduction component 113 can absorb the noise transmitted to the roof mounting plate 130 to further reduce the noise transmitted to the interior of the vehicle, thereby helping to further improve the user's driving experience.

[0056] like Figure 3 As shown, in some embodiments of the present invention, the noise reduction component 113 includes a third noise reduction layer 1131, a fourth noise reduction layer 1132 and a fifth noise reduction layer 1133. The third noise reduction layer 1131 is bonded to the front cross beam upper plate 111, the fourth noise reduction layer 1132 is bonded to the front cross beam lower plate 112, and the fifth noise reduction layer 1133 is disposed between the third noise reduction layer 1131 and the fourth noise reduction layer 1132.

[0057] By making the third noise reduction layer 1131 and the fourth noise reduction layer 1132 fit with the front cross beam upper plate 111 and the front cross beam lower plate 112 respectively, it is beneficial to improve the filling effect of the noise reduction component 113 and to ensure the sound absorption effect of the third noise reduction layer 1131 and the fourth noise reduction layer 1132. At the same time, the fifth noise reduction layer 1133 is arranged between the third noise reduction layer 1131 and the fourth noise reduction layer 1132, so that the noise reduction component 113 forms a multi-layer noise reduction structure, which is beneficial to improve the noise reduction effect of the noise reduction component 113, thereby helping to further reduce the noise transmitted into the vehicle.

[0058] In some embodiments of the present invention, the third noise reduction layer 1131 is constructed as a sound-absorbing cotton layer to consume the energy excited on the front crossbeam upper plate 111, improve the sound absorption performance of the roof crossbeam, and reduce the noise transmitted into the vehicle.

[0059] The fourth noise reduction layer 1132 is configured as a cotton block layer, so that the fourth noise reduction layer 1132 can play a sound absorption role while having a supporting force, facilitating the setting of the fifth noise reduction layer 1133 on the fourth noise reduction layer 1132, and being conducive to ensuring the supporting effect of the fourth noise reduction layer 1132 on the fifth noise reduction layer 1133.

[0060] The fifth noise reduction layer 1133 includes a plurality of resonance rubber particles. The plurality of resonance rubber particles are laid between the third noise reduction layer 1131 and the fourth noise reduction layer 1132 to form the fifth noise reduction layer 1133. When energy is transmitted on the noise reduction component 113, it can cause the plurality of resonance rubber particles to vibrate to consume energy, thereby reducing the noise transmitted into the vehicle.

[0061] Optionally, the third noise reduction layer 1131 is configured as a sound-absorbing cotton layer, the fourth noise reduction layer 1132 is configured as a cotton block layer, and at the same time the fifth noise reduction layer 1133 is formed by laying a plurality of resonance rubber particles, so that the noise reduction component 113 is formed into a composite multi-layer noise reduction structure with sound absorption - sound insulation - sound absorption effects, improving the noise reduction effect of the noise reduction component 113.

[0062] In addition, the first noise reduction layer 131 can be configured as a sound-absorbing cotton layer to consume the energy excited on the mounting plate 130 and improve the sound absorption performance of the mounting plate 130.

[0063] As Figure 4 shown, in some embodiments of the present utility model, a plurality of weight reduction holes 1111 are provided on the front crossbeam upper plate 111 to achieve weight reduction and cost reduction of the roof mounting beam 110, and noise can be transmitted to the noise reduction component 113 through the weight reduction holes 1111. The noise reduction component 113 can absorb the noise transmitted to the roof mounting beam 110. Thus, the roof mounting beam 110 achieves weight reduction and cost reduction while also having a noise reduction effect.

[0064] Among them, the plurality of weight reduction holes 1111 can be arranged at intervals along the length direction of the front crossbeam upper plate 111, so as to improve the effect of weight reduction and cost reduction of the front crossbeam upper plate 111 while being conducive to ensuring the structural strength of the front crossbeam upper plate 111 and reducing the risk of deformation of the front crossbeam upper plate 111.

[0065] Optionally, the number of the weight reduction holes 1111 can be 3, 4, 5, etc. The specific number of the weight reduction holes 1111 can be determined according to actual production requirements and is not specifically limited herein.

[0066] Referring to Figure 5 , in some embodiments of the present utility model, no weight reduction holes 1111 are provided on the front crossbeam lower plate 112 to avoid noise directly transmitted into the vehicle through the weight reduction holes 1111 on the front crossbeam lower plate 112, which is conducive to further reducing the noise transmitted into the vehicle and improving the driving and riding experience of users.

[0067] Combined Figures 1 to 3 Figures 1 to 3 , in some embodiments of the present utility model, the mounting plate 130 is provided with a raised portion 132 which bulges towards the side away from the roof mounting beam 110, and the raised portion 132 and the roof mounting beam 110 define a mounting cavity 140, and the radar assembly 120 is arranged in the mounting cavity 140.

[0068] By providing the raised portion 132 on the mounting plate 130, the mounting plate 130 can avoid the radar assembly 120, facilitating the installation of the radar assembly 120 onto the roof mounting beam 110. Moreover, the raised portion 132 and the roof mounting beam 110 can jointly define the mounting cavity 140, and the radar assembly 120 can be arranged in the mounting cavity 140 so that the mounting plate 130 can shield the radar assembly 120, enabling the mounting plate 130 to play a role in protecting the radar assembly 120.

[0069] Among them, a transmitting surface 1211 is provided on the radar body 121, and the transmitting surface 1211 is disposed opposite to the side of the raised portion 132 perpendicular to the noise reduction component 113, facilitating the radar body 121 to emit signals to detect obstacles.

[0070] Optionally, the raised portion 132 can be integrally formed with the mounting plate 130 for easy vehicle assembly, or the raised portion 132 can be detachably provided and fixedly connected to the mounting plate 130 for easy replacement and repair of the mounting plate 130 or the raised portion 132.

[0071] Next, combined with Figure 1 and Figure 3 briefly describe the structure of the vehicle implemented by the present utility model and the achieved noise reduction effect.

[0072] The vehicle includes a roof mounting beam 110, a radar assembly 120, and a mounting plate 130. A radar assembly 120 is provided on one side of the roof mounting beam 110, and the mounting plate 130 is located on the side of the radar assembly 120 away from the roof mounting beam 130. A first noise reduction layer 131 is provided on the side of the mounting plate 130 opposite to the radar assembly 120, and second noise reduction layers 122 are respectively provided on both sides of the radar body 121 opposite to the mounting plate 130 and the roof mounting beam 110.

[0073] A third noise reduction layer 1131, a fifth noise reduction layer 1133, and a fourth noise reduction layer 1132 are successively provided between the front crossbeam upper plate 111 and the front crossbeam lower plate 112 of the roof mounting beam 110.

[0074] When the vehicle is traveling at high speed, noise is transmitted to the first noise reduction layer 131 through the mounting plate 130. The first noise reduction layer 131 consumes the energy excited on the mounting plate 130. The energy consumed by the first noise reduction layer 131 is further transmitted to the second noise reduction layer 122, which can further absorb the noise and at the same time reduce the interference of vibration to the radar body 121.

[0075] When the noise is transmitted to the roof mounting beam 110, the third noise reduction layer 1131 absorbs a part of the noise transmitted to the roof mounting beam 110. When the noise is further transmitted to the fifth noise reduction layer 1133, the noise causes the vibration of multiple resonance rubber particles to further consume the noise. When the noise is further transmitted to the fourth noise reduction layer 1132, the fourth noise reduction layer 1132 further absorbs the noise.

[0076] Thus, by setting multiple noise reduction layers, the noise is gradually weakened on the transmission path of the noise, so as to improve the sound absorption and noise reduction performance of the vehicle, reduce the noise transmitted to the cabin, which is beneficial to improving the NVH performance of the front windshield area of the vehicle and enhancing the driving and riding experience of users.

[0077] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
