The utility model is used when in use:
1. in the horizontal direction
During the speed change driving of the transport means, in particular in the rapid acceleration state or the rapid stop state, the protected object is excited by an external force from the horizontal direction. The connecting end cap 4 is excited by external force from the protected object and then is in a left or right reciprocating motion state. The first metal rubber slider 5 and the first elastic support plate 2 are jointly in a leftward or rightward linear motion state under the excitation of external force. In this process, the first elastic support plate 2 is continuously elastically deformed in accordance with the direction of the external force. The first metal rubber slide block 5 moves towards the direction of external force excitation until colliding with the second metal rubber slide block 6, at this time, the first metal rubber slide block 5 not only can drive the second metal rubber slide block 6 to linearly slide towards the same direction of external force excitation, but also drives the second elastic support plate 3 and the spring limiting plate 10 to move towards the direction of external force excitation until the first elastic support plate 2 and the second elastic support plate 3 have enough elastic force to counteract the external force excitation from, at this time, the whole device can drive the heat exchanger to return to the original balance state, so as to achieve the effect of vibration isolation and centrifugal force impact reduction in the horizontal direction.
In the process, the mounting frame 9 can smoothly move along the moving groove 11 of the spring limiting plate 10, so that the spring is ensured not to deform. The rubber damping device 7 can support the first elastic support plate 2, so that the elastic support plate is prevented from being greatly deformed in the vertical direction when being excited by horizontal external force, a sliding rail is also designed in the rubber damping device 7 to ensure that rubber cannot be compressed, and the upper end limiting plate 73 and the sliding support rod 72 form a sliding pair to resist external force impact in the horizontal direction. And the second elastic support plate 3 is continuously elastically deformed in the process. The external force excitation consumes energy through the elastic deformation process of the first elastic support plate 2 and the second elastic support plate 3 so as to slow down the external force excitation born by the support, thereby overcoming the vibration impact caused by the left-right movement change of the heat exchanger. The first metal rubber sliding block 5 drives the second metal rubber sliding block 6 to slide in the same direction, good damping and vibration isolation effects are achieved in the process of slight vibration and strong vibration, meanwhile, the metal rubber also has excellent energy absorption and energy consumption effects, energy impact transmitted by the heat exchanger can be absorbed and converted into friction heat energy to be absorbed and dissipated, and the structure is simple.
2. In the vertical direction
When the automobile runs on a road surface with uneven pavement, the heat exchanger is excited by irregular external force in the vertical direction, the connecting end cover 4 is in an upward or downward reciprocating motion state after being excited by the external force in the vertical direction, the first metal rubber sliding block 5 and the second metal rubber sliding block 6 are slightly deformed together to counteract the external force excitation, and meanwhile, the energy impact transmitted by the heat exchanger is absorbed and converted into friction heat energy for dissipation by means of the special vibration isolation performance of the metal rubber. The rubber damper 7 near the metal rubber slider also isolates the external force excitation by the vibration isolation performance of the rubber. The first elastic support plate 2 and the second elastic support plate 3 also elastically deform downwards in the process, so that the whole height of the support is sunk. Under the effect of external force, the upper supporting tube 91 moves to the cavity part inside the lower supporting tube 92, at this time, the overall height of the mounting frame 9 is reduced, at this time, the square spring 8 deforms due to the external force excitation, and elastic force in the opposite direction is generated to offset the external force excitation. The support has excellent damping performance, and meets the special working condition that the heat exchanger is arranged in a trunk of the automobile, so that the heat exchanger can adapt to the working states of the automobile in different variable speed motions.
When the vehicle runs on an uneven road surface, the connecting end cover 4 is excited by external force from the vertical direction and then is in an upward or downward reciprocating motion state, and the protected object is impacted by the external force in the vertical direction, so that the shaking of the protected object needs to be reduced in the vertical direction. When the external force excitation is transmitted to the rubber shock absorbing device 7 by the first elastic supporting plate 2, the upper limiting plate 73 drives the sliding supporting rod 72 to move downwards, the metal rubber 75 in the bushing 76 is compressed and deformed, and the whole rubber shock absorbing device begins to sink in height. The rubber ferrule 74 deforms due to compression and provides vibration isolation.
When the transportation means runs on an uneven road surface, the connecting end cover 4 is in an upward or downward reciprocating motion state after being stimulated by external force from the vertical direction, the protected object is impacted by the external force from the vertical direction, and at the moment, the vertical shaking of the protected object needs to be reduced in the vertical direction, and the special damping performance of the metal rubber material and the deformation friction energy consumption of the spring are mainly relied on.
External force impact in the vertical direction is transmitted to the spring limiting plate 10 through the first metal rubber sliding block 5, the second metal rubber sliding block 6, the first elastic supporting plate 2 and the second elastic supporting plate 3 in sequence, and in the process, the external force is primarily isolated by the metal rubber sliding blocks. The external force excitation after vibration isolation is transmitted to the mounting frame 9 from the spring limiting plate 10, and the upper supporting tube 91 and the lower supporting tube 92 of the mounting frame 9 relatively move under the action of the external force. At this time, the elastic force generated by the elastic member 94 and the clamping post 95 to the wall surface of the cavity cannot counteract the sum of the gravity and the external force excitation, the equilibrium state of the upper support tube 91 and the lower support tube 92 is broken, and the upper support tube 91 moves to the cavity part inside the lower support tube 92. The square spring 8 starts to work while the mounting frame 9 integrally contracts, and elastic force opposite to the external force direction can be generated after the square spring 8 is deformed to counteract the external force excitation. Make this design support possess vertical direction good shock-absorbing capacity. In extremely special cases, when the mounting frame 9 is excited by an external force particularly large, the elastic force generated by the elastic element 94 and the clamping post 95 on the wall surface of the cavity cannot reduce the external force. The spring limiting plate 10 has great downward acceleration, and in order to ensure the shock absorption effect of the spring, the lower supporting tube 92 is provided with a clamping groove 96, so that the upper supporting tube 91 has a buffering effect and plays a role in protecting the spring.
After the external force excitation is counteracted, the elastic force generated by the spring can push the spring limiting plate 10 to return to the balance position, the elastic element 94 and the clamping column 95 can start to shrink under the combined action of the elastic force of the square spring and the friction force of the cavity wall surface, the clamping column 95 moves upwards in the cavity in the supporting tube 91, and when the square spring returns to the original balance position, the deformation of the square spring is finished, and the design support completes a damping function in the vertical direction.
