In a first aspect, the present application provides a vibration-absorbing device 100, as shown in fig. 1-2, including a fixing member 110 and a vibration-absorbing member 120, the fixing member 110 including a bracket 111, a connecting member 112 and an adhesive member 113, the connecting member 112 being used to fix the vibration-absorbing device 100 to the bracket 111; the bonding member 113 is disposed on a side of the bracket 111 opposite to the shock absorbing assembly 120, the bonding member 113 includes a fixing surface 1131, and the fixing surface 1131 is attached to the vehicle body; the shock absorbing assembly 120 includes an elastic member 121 and a mass 122, the mass 122 is enclosed in the elastic member 121, and the shock absorbing assembly 120 is used to absorb vibrations generated during the operation of the vehicle body.
It should be noted that, one side of the bonding member 113 is fixed to the bracket 111, and the other side is provided with a fixing surface 1131 for bonding to the vehicle body, which is simpler and more convenient to fix through the bonding member 113 in a conventional manner of fixing through bolts, and is also easy to detach and replace, for example, when the vibration mode of the vehicle changes due to aging of the vehicle, a better vibration absorbing effect can be achieved by replacing the vibration absorbing assembly 120. By adopting the adhering mode, the arrangement of fixing structures such as bolts and the like can be reduced, the structure of the vibration absorption device 100 is simplified, and the manufacturing cost of the vibration absorption device 100 is reduced. And the mass 122 is wrapped inside the elastic member 121, so that the shock absorbing capability thereof can be improved.
It is possible that the adhesive member 113 covers the entire surface of the side of the bracket 111 opposite to the shock-absorbing assembly 120. It is understood that the larger the area of the adhesive member 113, the more firmly the vibration absorbing device 100 is adhered to the vehicle body.
Optionally, the bonding member 113 is a glue layer made of polyurethane glass glue. Because the polyurethane glass glue layer not only has better adhesive force, but also has the advantages of good wear resistance, large mechanical strength, good cohesiveness, good elasticity and the like, and has excellent recoverability, can be used for dynamic joints,
in one possible embodiment, as shown in fig. 3, the mass 122 is fixed to the contact surface of the elastic member 121.
Specifically, the elastic member 121 may be a silicone member, and the silicone member can satisfy the vibration absorption requirement of higher frequency compared to the conventional natural rubber, for example, the natural rubber may not satisfy the 78HZ frequency requirement, and the silicone rubber may satisfy the requirement. And the silica gel piece is coated on the outer surface of the mass block 122 through a vulcanization process. Compared with silica gel, obvious smell and resilience can appear in the natural rubber after the vulcanization and receive the influence, and too high hardness still can produce the phenomenon of rupture, and silica gel then can get rid of the taste completely to reach complete food level silica gel goods material with how much debris discharge in the sizing material.
Illustratively, the mass 122 may be an iron core. The iron core is selected, so that the cost can be reduced, and tests show that the iron core can adjust the higher vibration frequency of the vehicle body, so that a better vibration reduction effect is achieved.
In order to reduce the overall mass of the vibration absorbing device 100, as shown in fig. 4, the body of the bracket 111 has a plurality of lightening holes 1115, and the bracket 111 is made of plastic. The lightening holes 1115 may be arranged in a grid shape, and the positions of the lightening holes 1115 should be away from the fixing positions of the shock absorbing assembly 120 to facilitate the fixing of the shock absorbing assembly 120.
In addition, as shown in fig. 5, the bracket 111 is provided at an end region thereof near with a fixing protrusion 1116, and both ends of the shock-absorbing assembly 120 are respectively connected to the fixing protrusions 1116. The fixing protrusion 1116 is provided to facilitate the fixing of the shock absorbing assembly 120. It is understood that the fixing protrusions 1116 may be provided at either ends of the bracket 111, and a plurality of fixing protrusions 1116 may be provided in order to improve the reliability of the fixing. Generally, the fixing protrusions 1116 may be provided at both ends corresponding to the lengthwise direction of the shock absorbing member 120.
As shown in fig. 1-4, the connecting member further includes a stopper 114, the stopper 114 is disposed in the gap between the fixing protrusion 1116 and the end of the shock-absorbing device 100, and the fixing protrusion 1116 and the shock-absorbing assembly 120 are respectively fixed to opposite ends of the stopper 114. And the stopper 114 is fixed to the fixing projection 1116. The stopper 114 is used to fill up the gap between the vibration-absorbing device 100 and the stopper 114, so that the vibration-absorbing device 100 is more firmly fixed. It can be understood that the material of the stopper 114 may be an elastic member 121, which may be filled in the gap by interference, so as to achieve a more stable effect. The fixing of the fixing protrusion 1116 and the shock-absorbing assembly 120, and the fixing manner with the stopper 114, can be realized by bolts or clamping.
As for the specific fixing manner of the limiting block 114, as shown in fig. 4-5, in an alternative embodiment, at least one first fixing through hole is disposed on a side of the limiting block 114 facing the fixing protrusion 1116, and the fixing protrusion 1116 is disposed with a second fixing through hole at a position corresponding to the first fixing through hole; the connecting member 112 is sequentially disposed through the first and second fixing holes to fix the limiting block 114 to the fixing protrusion 1116.
Specifically, as shown in fig. 4, at least one of the first fixing through hole or the second fixing through hole may be configured as a nut 1141, for example, the first fixing through hole may actually be configured as a nut 1141 integrally formed with the stopper 114. The connecting member 112 further includes a bolt 115, and the stopper 114 is fixed to the fixing protrusion 1116 by the bolt 115. However, this is only one possible embodiment, and other fixing methods may be adopted, and are not particularly limited herein.
In a second aspect, as shown in fig. 6-7, the present application further provides a panoramic sunroof 200, which includes a sunroof glass 210 and the shock-absorbing device 100, wherein the shock-absorbing device 100 is directly attached to the sunroof glass 210 of the panoramic sunroof 200.
In traditional vehicle, the shock-absorbing device 100 on the panoramic sunroof 200 generally can be fixed on the framework of the vehicle ceiling through bolts, and this kind of setting mode is comparatively loaded down with trivial details when the shock-absorbing device 100 is installed or dismantled on the one hand, and is great to the limitation of the setting position of the shock-absorbing device. Since the vibration absorbing device 100 provided by the present application can be directly adhered to the skylight glass 210, the adhering position is not limited, and can be selected as required, and the above-mentioned problem can be solved well by using the vibration absorbing device 100 of the present embodiment that can be directly adhered to the panoramic skylight 200.
In the driving process, the vibration of the panoramic sunroof 200 in the state of the whole vehicle can be reduced by the reaction force generated when the glass vibration absorption device 100 resonates, and the occurrence of resonance with the whole vehicle and the generation of abnormal sound are avoided.
As shown in fig. 8, it is found through tests that if the resonant frequency of the conventional sunroof in the whole vehicle is 80HZ, and the vibration absorbing device 100 with the frequency of 80HZ is installed and developed as shown in curve a, and the vibration absorbing device 100 is installed on the panoramic sunroof 200 with the resonant frequency of 80HZ, the resonant frequency of the panoramic sunroof 200 and the vehicle body is reduced to 65HZ, and as shown in curve b, the mode is greatly reduced, and the resonance with the whole vehicle is avoided. Note that the mode is a natural vibration characteristic of the structural system. The free vibration of the linear system is decoupled into N orthogonal single degree of freedom vibration systems, corresponding to the N modes of the system. Each mode has a specific natural frequency, damping ratio and mode shape. On the other hand, when the 65HZ vibration absorbing apparatus 100 is installed in the panoramic sunroof 200 having the same frequency, the resonant frequency of the sunroof will rise instead, as shown by the curve c, and thus each vehicle should be adapted to the vibration absorbing apparatus 100 having a different vibration frequency. It should be noted that the natural frequency of the vibration absorbing device 100 must be designed and developed according to the calculated NVH theory or the measured value of the real vehicle, so as to avoid the adverse effect.
In addition, the vibration absorption device is simple and convenient to disassemble, so that the vibration absorbers with different frequencies can be selected and designed according to conditions such as different vehicle types or working conditions to meet the requirements of users on the NVH performance of the skylight.
Optionally, a plurality of shock absorbing devices 100 are attached to the skylight glass 210, and the shock absorbing devices 100 are attached to the edge of the skylight glass 210.
It is understood that a plurality of shock-absorbing devices 100 may be attached to the sunroof glass 210 as needed, and the shock-absorbing devices 100 may be disposed at the edge of the sunroof glass 210 in order to secure the aesthetic appearance of the panoramic sunroof 200 in order to prevent the panoramic sunroof 200 from being hidden.
In one embodiment, the shock-absorbing device 100 is attached to the sunroof glass 210 near the rear end of the vehicle body. Illustratively, as shown in fig. 6, the vibration absorbing devices are provided in two, and the two vibration absorbing devices are symmetrically attached to the rear end of the vehicle body.
