The invention will be described in detail below with reference to the drawings in connection with embodiments.
Example 1
The present embodiment relates to a decoupling film including a film body 1 in the shape of a disk, the film body 1 having a center portion 101, and an outer side portion 102 provided around the center portion 101. The thickness of the outer portion 102 is smaller than that of the central portion 101, and a liquid passage 104 is formed in the outer portion 102, and the liquid passage 104 penetrates the outer portion 102.
The thickness of the outer side 102 of the film body 1 is smaller than that of the central part 101, which is not only beneficial to fixing the central part 101, but also beneficial to reducing abnormal sound generated when the outer side 102 floats, and meanwhile, through the through liquid hole 104 penetrating the outer side 102, abnormal sound generated by the decoupling film in large amplitude can be prevented, so that the decoupling film has a good noise reduction effect.
It should be noted that, the decoupling film in this embodiment is mainly located in the damping fluid in the vibration reduction component in the prior art. When vibration excitation is transmitted to the vibration damping member, the outer portion 102 floats in the damping liquid through the decoupling film, thereby playing a role of damping vibration excitation. In order to facilitate the description of the structure of the decoupling film, the vibration damping member will be described below as a hydraulic suspension.
Based on the above general description, one exemplary structure of the decoupling film described in the present embodiment is shown in fig. 1 to 3. The disc-shaped membrane body 1 is arranged between the upper flow field plate 2 and the lower flow field plate 3, the connection of the upper flow field plate 2 and the lower flow field plate 3 here and the arrangement of the two in the hydraulic suspension are referred to in the prior art.
As a preferred embodiment, the center portion 101 in the present embodiment is located at the center position of the entire membrane body 1, is fixed between the upper flow field plate 2 and the lower flow field plate 3, and is provided corresponding to a through hole provided through the center positions of the upper flow field plate 2 and the lower flow field plate 3 to block the through hole.
An annular cavity is defined between the upper runner plate 2 and the lower runner plate 3, and an outer side 102 is specifically disposed in the cavity, the outer side 102 is integrally annular, is connected to the outer edge of the central portion 101, and has a gap with the cavity, and when high-frequency vibration is transferred to the hydraulic mount, vibration excitation is damped through floating of the outer side 102 in the cavity.
In this embodiment, the thickness of the outer portion 102 is smaller than that of the central portion 101, which is beneficial to improving the fixing effect of the central portion 101 between the upper runner plate 2 and the lower runner plate 3, and improving the floating effect of the outer portion 102 in the cavity, and reducing abnormal sound caused by collision of the outer portion 102 to the upper runner plate 2 and the lower runner plate 3, so as to improve the noise reduction effect of the decoupling film.
In particular, the membrane body 1 in this embodiment may be made of rubber, so as to facilitate the floating of the outer portion 102 with respect to the central portion 101, and the deformation and recovery of the outer portion 102 during the floating, and at the same time, reduce abnormal noise generated when the upper flow channel plate 2 and the lower flow channel plate 3 collide. Of course, the membrane body 1 may be made of other materials having elastic deformability in the prior art, as long as the outer portion 102 can float in the cavity and has better stability in use in damping fluid.
In order to improve the fixing effect and the fixing reliability of the center portion 101 between the upper flow field plate 2 and the lower flow field plate 3, convex abutting portions are formed on both side end surfaces of the center portion 101. As shown with reference to fig. 1 and 2, the abutment portion is preferably an annular abutment projection 1011 extending in the circumferential direction of the central portion 101, and the abutment projection 1011 is disposed on the side close to the outer portion 102 and is a plurality of abutment projections disposed so as to be nested in the radial direction of the central portion 101.
Here, the provision of the plurality of abutment projections 1011 facilitates an increase in friction between the center portion 101 and the upper and lower flow field plates 2 and 3, thereby facilitating an improvement in fixing effect and stability in use of the center portion 101 between the upper and lower flow field plates 2 and 3. The plurality of abutting projections 1011 are arranged on the side close to the outer side 102, so that damping fluid outside the upper flow channel plate 2 and the lower flow channel plate 3 is facilitated to act on the central part 101 through the through holes on the upper flow channel plate 2 and the lower flow channel plate 3, and the part of the central part 101 which is not fixed by the upper flow channel plate 2 and the lower flow channel plate 3 can be deformed, so that vibration excitation is attenuated.
In addition, the innermost abutment projection 1011 and the central portion 101 define a recess 1013 therebetween, which is advantageous in enhancing the vibration damping effect of the central portion 101 when impacted by the damping fluid.
It will be appreciated that the abutment projections 1011 in this embodiment may also be provided only on one side end face thereof of the central portion 101, except that the fixing effect is slightly inferior to the case where the abutment projections 1011 are provided on both side end faces of the central portion 101.
In addition, in order to further enhance the positioning effect of the center portion 101 between the upper flow field plate 2 and the lower flow field plate 3, as shown in fig. 1 and 2, at least two positioning holes 1012, as shown in the three positioning holes 1012, are provided through the center portion 101 in the thickness direction thereof. Three locating holes 1012 are disposed adjacent one side of the outer portion 102. The positioning holes 1012 are used for the positioning structure on the upper flow channel plate 2 or the lower flow channel plate 3 to pass through, thereby facilitating further improvement of the fixing effect of the center portion 101 between the upper flow channel plate 2 and the lower flow channel plate 3.
The through-liquid hole 104 in this embodiment is an arc hole extending along the circumferential direction of the outer side 102, the structure of the arc hole is simple, the arc hole is convenient for processing and forming, and the arc hole is beneficial to reducing the flow resistance when the damping liquid flows through the through-liquid hole 104, and further beneficial to the flow of the damping liquid through the through-liquid hole 104, so that the flow damping of the damping liquid is reduced.
In specific implementation, as shown in fig. 2, 3 and 4, the plurality of liquid through holes 104 are on the same circumference, the plurality of liquid through holes 104 are sequentially arranged along the circumferential direction, and connecting ribs 103 are arranged between adjacent liquid through holes 104. Here, the arrangement of the plurality of liquid through holes 104 is beneficial to improving the efficiency of the damping liquid flowing through the outer portion 102, so as to further improve the noise reduction effect of the decoupling film in use. Preferably, the positions of the liquid passing holes 104 are arranged corresponding to the damping holes on the upper runner plate 2 and the lower runner plate 3, so that the use effect of the liquid passing holes 104 is improved.
In this embodiment, the portion of the outer portion 102 located inside each of the liquid passing holes 104 and the portion of the outer portion 102 located outside each of the liquid passing holes 104 are connected together by each of the connecting ribs 103. For convenience of description, in the present embodiment, a portion of the outer side portion 102 located inside each of the via holes 104 is referred to as a first side portion 1021, and a portion of the outer side portion 102 located outside each of the via holes 104 is referred to as a second side portion 1022.
The first side portion 1021 and the second side portion 1022 are both in a ring shape, the inner edge of the first side portion 1021 is connected to the outer edge of the central portion 101, and the inner edge of the second side portion 1022 is connected to the outer edge of the first side portion 1021 via the plurality of connecting ribs 103. That is, the first side 1021, the second side 1022, and the adjacent two connecting ribs 103 define the respective liquid through holes 104 therebetween.
The plurality of connecting ribs 103 not only can realize connection between the first side 1021 and the second side 1022, but also is beneficial to forming the liquid through holes 104, so that the use effect is good. Particularly, when the damping fluid impacts the through-hole 104, the flow area of the through-hole 104 increases, so that the damping fluid can flow through the through-hole 104. And because of the arrangement of the plurality of connecting ribs 103, when the outer side 102 floats in the cavity, the second side 1022 floats by a larger extent than the first side 1021 when the first side 1021 and the second side 1022 float. So set up, not only do benefit to further reduce the abnormal sound that produces because of the collision of whole lateral part 102 to runner board 2 and runner board 3 down, but also do benefit to the damping fluid in through-liquid hole 104 to and the flow in lateral part 102 and the clearance between the cavity, and then can improve the damping effect of decoupling film to the vibration, noise reduction effect and stability in the use.
It should be noted that, the number and the specification of the connecting ribs 103 may be set according to specific use requirements, so long as the arc shape of the through-liquid hole 104 is ensured on the premise of meeting the elastic connection of the first side portion 1021 and the second side portion 1022.

When the decoupling film is attached to the upper flow field plate 2 or the lower flow field plate 3 due to vibration excitation, the damping fluid can flow through the flow field 300 and the fluid passage holes 104. Due to the impact of the damping fluid on the liquid passing hole 104, the liquid passing hole 104 is enlarged, so that more damping fluid can flow through the liquid passing hole 104, and the problem of abnormal sound generated when the damping fluid flows is reduced. And has better noise reduction effect and use stability.
