[0024] In combination with Figures 1 to 3 It shows one example of the high-reliability fastening assembly provided by the utility model.

[0025] As shown in the figure, the high-reliability fastening assembly of the present example is used in cooperation with the automobile radar support and the automobile body, mainly comprising a threaded rod 1, a reinforcing layer 2 and a protective layer 3.

[0026] The reinforcing layer 2 is arranged outside the nail head 11 of the threaded rod 1 and is configured in an I-shaped distribution, and the protective layer 3 is arranged on the outer circumferential surface of the reinforcing layer 2 and forms a placement cavity capable of accommodating the automobile radar support 4 between the first end surface 31 and the second end surface 32 of the protective layer 3. The bottom surfaces of the first end surface 31 and the second end surface 32 are respectively formed with a damping structure 33 and / or a waterproof structure 34 for cooperation with the automobile radar support 4 and the automobile body 5, so that the cooperation of the reinforcing layer 2 and the protective layer 3 can enhance the connection strength of the threaded rod 1 and achieve damping and waterproof, thereby improving the connection stability and reliability of the automobile radar support 4 and the automobile body 5.

[0027] In combination Figure 3 The threaded rod 1 is configured in a T-shaped distribution, and the bottom of the nail head 11 of the threaded rod 1 extends outward to form a support plate 12 for cooperation with the reinforcing layer 2, so that the reinforcing layer 2 is arranged outside the nail head 11, and the bottom surface of the reinforcing layer 2 is connected with the support plate 12, which can effectively support the reinforcing layer 2 and ensure the stable connection of the threaded rod 1 with the reinforcing layer 2.

[0028] Meanwhile, the reinforcing layer 2 is configured in an I-shaped distribution, so that the support plate 12 cooperates with the reinforcing layer 2, and the reinforcing layer 2 can effectively disperse the stress borne by the threaded rod 1. The bottom surface of the reinforcing layer 2 is further formed with a protruding tooth ring 21, so that the reinforcing layer 2 can increase the contact area between the threaded rod 1 and the automobile body 5 and increase the friction force between the threaded rod 1 and the automobile body 5, thereby improving the strength of the threaded rod 1 and making the connection of the automobile radar support 4 and the automobile body 5 stable and reliable.

[0029] Further, the nail head 11 is distributed with a plurality of connecting grooves 13, so that the reinforcing layer 2 can be embedded in the connecting grooves 13 and form interlocking connection with the nail head 11, which can not only ensure the stable connection of the threaded rod 1 with the reinforcing layer 2, but also increase the friction force between the threaded rod 1 and the reinforcing layer 2. The reinforcing layer 2 can disperse the vibration and external force received by the threaded rod 1, so as to prevent the threaded rod 1 from loosening or falling off during use, thereby enhancing the connection strength of the threaded rod 1.

[0030] In addition, the reinforcing layer 2 is composed of a plastic piece, preferably a nylon piece, so that the reinforcing layer 2 has strong anti-loosening ability and can effectively reinforce the nail head 11 of the threaded rod 1 to prevent the threaded rod 1 from loosening during connection. Meanwhile, the nylon piece has a certain elasticity, so that the reinforcing layer 2 can absorb the vibration energy of the threaded rod 1 and reduce the vibration and noise of the connection of the threaded rod 1 with the automobile radar support 4 and the automobile body 5.

[0031] The outer circumferential surface of the reinforcing layer 2 is provided with a protective layer 3, so that the protective layer 3 can effectively protect the threaded rod 1, reduce the vibration and noise generated by the connection of the threaded rod 1 with the automobile radar support 4 and the vehicle body 5, and improve the reliability of the connection of the automobile radar support 4 and the vehicle body 5.

[0032] In combination Figure 3 And Figure 4 Specifically, the protective layer 3 is wrapped around the outer circumferential surface of the protective layer 3 to form a U-shaped distribution, protecting the protective layer 3 and forming a placement cavity between the first end surface 31 and the second end surface 32 of the protective layer 3 to accommodate the automobile radar support 4. When the threaded rod 1 penetrates the vehicle body 5, the bottom surface of the second end surface 32 abuts against the vehicle body 5, and the automobile radar support 4 is embedded between the first end surface 31 and the second end surface 32, thereby connecting the automobile radar support 4 and the vehicle body 5 through the threaded rod 1.

[0033] In order to protect the automobile radar support 4 and the vehicle body 5, prevent water from entering the connection, and reduce the vibration of the automobile radar support 4, the bottom surfaces of the first end surface 31 and the second end surface 32 of the protective layer 3 are respectively formed with a damping structure 33 and a waterproof structure 34 for cooperation with the automobile radar support 4 and the vehicle body 5.

[0034] Further, the damping structure 33 is configured in an annular shape and is respectively protruded on the bottom surfaces of the first end surface 31 and the second end surface 32. As a preferred arrangement, a first damping structure 331 is arranged in the middle region of the bottom surface of the first end surface 31, so that when the automobile radar support 4 is embedded between the first end surface 31 and the second end surface 32, the first damping structure 331 on the bottom surface of the first end surface 31 protects the automobile radar support 4 from damage and absorbs the energy generated by the vibration of the automobile radar support 4, thereby reducing the vibration and noise of the automobile radar support 4.

[0035] Correspondingly, a second damping structure 332 is arranged at the end of the bottom surface of the second end surface 32 that cooperates with the tooth ring 21 of the protective layer 3, so that when the threaded rod 1 penetrates the vehicle body 5 and the bottom surface of the second end surface 32 abuts against the vehicle body 5, the second damping structure 332 can abut against the vehicle body 5 to protect the vehicle body 5 and absorb the energy generated by the vibration of the vehicle body 5.

[0036] Here, the bottom surface of the damping structure 33 is configured in an arc shape to effectively absorb and disperse energy and reduce the transmission of vibration. The first damping structure 331 and the second damping structure 332 thus formed cooperate to effectively block the vibration propagation path of the automobile radar support 4, thereby achieving damping and noise reduction.

[0037] At the same time, the second damping structure 332 also forms a sealing and waterproof structure to seal the vehicle body 5 and prevent water from entering.

[0038] Further, the waterproof structure 34 is arranged at the outer end of the bottom surface of the second end surface 32 and extends to the outside of the second end surface 32, so that when the bottom surface of the second end surface 32 abuts against the vehicle body 5, the waterproof structure 34 can abut against the vehicle body 5 and extend to the outside, effectively sealing the connection between the threaded rod 1 and the vehicle body 5, so that the second damping structure 332 and the waterproof structure 34 cooperatively form two sealing waterproof structures, ensuring the stable and reliable connection of the automobile radar support 4 and the vehicle body 5.

[0039] In addition, the protective layer 3 is composed of a rubber part, preferably EPDM rubber, which has strong high-temperature resistance, chemical resistance, aging resistance, bending performance, elasticity and wear resistance, effectively protecting the reinforcing layer 2 and preventing aging, and the bending performance, elasticity and wear resistance of the damping structure 33 and the waterproof structure 34 effectively protect the automobile radar support 4 and the vehicle body 5 to achieve damping and waterproofing, thereby improving the connection strength of the threaded rod 1 and the reliability and stability of the connection of the automobile radar support 4 and the vehicle body 5.

[0040] The reinforcing layer 2 and the protective layer 3 thus formed can cooperate with each other to improve the connection strength of the threaded rod 1 while achieving damping and waterproofing.

[0041] In combination Figure 1 and Figure 2 In some embodiments, the first end surface 31 of the protective layer 3 cooperates with the upper region of the reinforcing layer 2 to form a rectangular cross section, so that the cooperation of the first end surface 31 and the upper region of the reinforcing layer 2 can stably connect the automobile radar support 4 and improve the connection strength of the threaded rod 1, and the second end surface 32 of the protective layer 3 cooperates with the lower region of the reinforcing layer 2 to form a circular cross section, so that the cooperation of the second end surface 32 and the lower region of the reinforcing layer 2 can effectively seal the vehicle body 5.

[0042] The following illustrates the working process of the application in specific application, and it should be noted that the content described herein is only a specific application example of the application and does not limit the application.

[0043] In combination Figure 4 The threaded rod 1 penetrates into the vehicle body 5, the automobile radar support 4 is embedded between the first end surface 31 and the second end surface 32 of the protective layer 3, and the automobile radar support 4 and the vehicle body 5 are stably connected through the cooperation of the nut 6 and the threaded rod 1.

[0044] At this time, the reinforcing layer 2 outside the threaded rod 1 can effectively disperse the vibration and external force received by the threaded rod 1, preventing the threaded rod 1 from loosening or falling off during use, thereby enhancing the connection strength of the threaded rod 1.

[0045] Meanwhile, the first end surface 31 of the protective layer 3 abuts against the automobile radar support 4, and the first damping structure 331 of the first end surface 31 protects the automobile radar support 4 from being damaged, absorbs the energy generated by the vibration of the automobile radar support 4, and reduces the vibration and noise of the automobile radar support 4.

[0046] Correspondingly, when the second end surface 32 of the protective layer 3 abuts against the vehicle body 5, the second damping structure 332 of the second end surface 32 protects the vehicle body 5, absorbs the energy generated by the vibration of the vehicle body 5, cooperates with the first damping structure 331 to block the vibration propagation path, and thus realizes the damping and noise reduction.

[0047] The waterproof structure 34 at the end of the second end surface 32 abuts against the vehicle body 5 and extends outward, cooperates with the second damping structure 332 to form two sealing waterproof structures, seals the vehicle body 5, prevents water from entering, and thus ensures the connection stability and reliability of the automobile radar support 4 and the vehicle body 5.

[0048] The high-reliability fastening assembly provided by the utility model can effectively improve the connection strength of the threaded rod 1 by cooperation of the reinforcing layer 2 and the protective layer 3, ensure the damping performance and waterproof performance of the connection, and ensure the stable and reliable connection.
