Description

Technical Field

[0001] The utility model relates to the technical field of automotive radar damping sheets, in particular to an efficient noise-reducing automotive radar damping sheet. Background Technique

[0002] The damping sheet, also known as mastic or damping block, is a viscoelastic material pasted on the inner surface of the vehicle body. The damping sheet made of polymer material or rubber material has stable physical and chemical properties, excellent vibration and noise reduction performance, heat resistance, cold resistance, anti-aging property and strong adhesiveness. When installing automotive radar, noise reduction is usually achieved through the damping sheet.

[0003] After retrieval, the patent with the publication number CN211280895U discloses a damping sheet for automobiles with shock absorption and noise reduction, especially related to the technical field of damping sheets, including a damping sheet body and a fixing sheet. The fixing sheet is bonded above the damping sheet body, and fixing caps are embedded at the four corners of the upper end of the fixing sheet, and screw holes are opened at the upper end of each fixing cap. By fixing the fixing sheet with a screw head and then attaching the damping sheet body to the fixing sheet, the damping sheet body can be installed. When disassembling, since the damping sheet body and the fixing sheet are adhered as the upper magnetic strip and the lower magnetic strip attract each other, it is more convenient to disassemble the damping sheet body; through the heat insulation layer in the fixing sheet, not only the heat insulation property of the damping sheet body can be improved, but also the sound insulation effect of the damping sheet body can be further enhanced through the first sound insulation layer and the second sound insulation layer, solving the problems that the existing damping sheet is not easy to disassemble and the sound insulation effect is average.

[0004] The following problems exist in the use of the damping sheet in the prior art:

[0005] Although it is convenient to disassemble and replace the damping sheet, the strength of the damping sheet is low during use, and it is easy to break, resulting in a short service life. Content of the Utility Model

[0006] The purpose of the utility model is to solve the shortcomings that although it is convenient to disassemble and replace the damping sheet in the prior art, the strength of the damping sheet is low during use, and it is easy to break, resulting in a short service life, and to propose an efficient noise-reducing automotive radar damping sheet.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] An efficient noise-reducing automotive radar damping sheet, including a damping sheet main body, the damping sheet main body is composed of a first damping sheet and a sound insulation layer, and the sound insulation layer is arranged below the first damping sheet;

[0009] A fracture prevention mechanism, which is arranged on the first damping sheet to strengthen the fracture prevention of the damping sheet main body.

[0010] In a possible design, the anti-breakage mechanism includes two anti-breakage rings for strengthening the anti-breakage of the damper plate body. One side of the two anti-breakage rings close to each other is fixedly connected to the bottom and top of the first damper plate respectively, and the top of the sound insulation layer is fixedly connected to the bottom of the anti-breakage ring.

[0011] In a possible design, a second rubber ring for increasing the friction between the sound insulation layer and the device for anti-slip is fixedly arranged at the bottom of the sound insulation layer, and a first rubber ring for increasing the friction between the anti-breakage ring and the device for anti-slip is fixedly arranged at the top of the anti-breakage ring above the first damper plate.

[0012] In a possible design, the anti-breakage ring is made of nylon cloth.

[0013] In a possible design, the sound insulation layer is made of sound insulation felt.

[0014] In a possible design, grooves for further increasing the friction are provided at the top of the first rubber ring and the bottom of the second rubber ring.

[0015] In this application, through the provided anti-breakage ring, the strength of the damper plate body can be effectively improved during use, avoiding the breakage of the damper plate body, extending the service life. Since the anti-breakage ring is made of nylon cloth, nylon cloth has excellent strength and durability, is wear-resistant and has a long service life. Of course, other materials such as natural rubber can also be selected. (It should be noted that the top of the sound insulation layer is fixed to the bottom of the anti-breakage ring and the bottom of the first damper plate, so that the anti-breakage ring is wrapped between the sound insulation layer and the first damper plate, and the first rubber ring is between the anti-breakage ring and the first damper plate). Through the provided sound insulation layer, the sound insulation layer can improve the noise reduction effect of the damper plate body. The sound insulation layer is made of sound insulation felt, and the sound insulation felt can effectively reduce the spread of noise for noise reduction. Cooperating with the use of the first damper plate, the noise reduction effect is better and more efficient. Among them, the first damper plate is made of rubber material.

[0016] The beneficial effects in this utility model are as follows:

[0017] In this utility model, for the high-efficiency noise reduction type automotive radar damper plate, through the anti-breakage mechanism and the anti-breakage ring, the strength of the damper plate body can be effectively improved during use, avoiding the breakage of the damper plate body and extending the service life;

[0018] In this utility model, through the anti-breakage mechanism, the strength of the damper plate body can be effectively improved during use, avoiding the breakage of the damper plate body and extending the service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Embodiment

[0025] Refer to Figures 1-4 , an efficient noise-reducing damping sheet, comprising: a damping sheet main body 1 and an anti-break mechanism. The damping sheet main body 1 includes a first damping sheet 5 and a sound insulation layer 6. The sound insulation layer 6 is arranged below the first damping sheet 5 and is used to reduce the noise transmission generated by the radar.

[0026] The anti-break mechanism is provided to enhance the anti-break performance of the damping sheet main body 1. Specifically, the anti-break mechanism includes two anti-break rings 4, which are respectively fixed to the bottom and top of the first damping sheet 5. The sides of the two anti-break rings 4 close to each other are tightly connected to the first damping sheet 5 to form a strengthened structure, improving the overall strength of the damping sheet main body 1. At the same time, the top of the sound insulation layer 6 is fixedly connected to the bottom of the lower anti-break ring 4, further enhancing the structural stability of the damping sheet main body 1.

[0027] This application is used in the field of automotive radar and can also be used in other fields applicable to this application. Embodiment

[0028] Refer to Figures 1-4 , on the basis of Embodiment 1, an improvement is made: an efficient noise-reducing automotive radar damping sheet, which is applied in the field of automotive radar,

[0029] The material of the anti-break ring 4 is nylon cloth. Nylon cloth has excellent strength and durability, and can effectively prevent the damping sheet main body 1 from breaking when subjected to external impact or vibration.

[0030] In order to increase the frictional force between the damper sheet main body 1 and the mounting device and prevent sliding or falling off during use, in this embodiment, a second rubber ring 7 is provided at the bottom of the sound insulation layer 6. The second rubber ring 7 is fixedly connected to the sound insulation layer 6 to form a soft contact surface, increasing the frictional force with the mounting device. At the same time, a first rubber ring 3 is provided at the top of the anti-breaking ring 4 above the first damper sheet 5, which also plays the same anti-slip role.

[0031] In order to further increase the frictional force, in this embodiment, grooves 2 are opened at the top of the first rubber ring 3 and the bottom of the second rubber ring 7. These grooves 2 can increase the contact area between the rubber ring and the mounting device, further improving the anti-slip effect.

[0032] The material of the sound insulation layer 6 is sound insulation felt. Sound insulation felt is an efficient sound insulation material that can effectively absorb and isolate the transmission of sound. Using sound insulation felt as the material of the sound insulation layer 6 can significantly improve the noise reduction effect of the damper sheet main body 1 and provide a quieter working environment for automotive radars.

[0033] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
