Detailed Description
It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1 to 4, the suspension apparatus is applied to a vehicle, and includes a carrier plate 60, a driving plate 42, a first elastic member 10, and a second elastic member 20;

the bearing plate 60 is connected to one end of the first elastic member 10, and one end of the second elastic member 20 is connected to the driving plate 42.
When the bearing plate 60 is pressed by the functional element 30 requiring vibration reduction, one end of the first elastic element 10 connected with the bearing plate 60 is compressed, and the first elastic element 10 provides a buffering force for the functional element 30 requiring vibration reduction. When the first elastic element 10 and the second elastic element 20 are both under pressure, the first elastic element 10 and the second elastic element 20 together provide a damping force for the functional element 30 requiring damping. Thus, the suspension device can adapt to different road conditions, and can realize better vibration and noise reduction effects on the functional element 30 of the vehicle through the first elastic element 10 on the flat road conditions when the load of the functional element 30 is smaller than the first preset threshold value. And, on the off-road condition, when the load of the functional part 30 is greater than or equal to the first preset threshold value, the second elastic part 20 can achieve better vibration and noise reduction effects on the functional part 30 of the vehicle, so that the functional part 30 can obtain better buffering on both the flat road condition and the off-road condition, the functional part 30 of the vehicle is prevented from being damaged or even losing efficacy, and the driving safety of the vehicle is improved.
In this embodiment of the application, optionally, the first elastic element 10 includes a first end 11 and a second end 12 that are disposed opposite to each other, the second end 12 is connected to the carrier plate 60, the second elastic element 20 includes a third end 21 and a fourth end 22 that are disposed opposite to each other, the third end 21 is connected to the drive plate 42, the third end 21 is disposed on the same side as the first end 11, and the fourth end 22 is disposed on the same side as the second end 12. The driving plate 42 drives the third end 21 of the second elastic member 20 to move toward the fourth end 22, so as to enhance the damping force of the second elastic member 20.
In the embodiment of the present application, in the case that the load of the functional element 30 of the vehicle is smaller than the first preset threshold, the second end 12 of the first elastic element 10 is under pressure, and at this time, the functional element 30 abuts against the second end 12 of the first elastic element 10, and the first elastic element 10 provides a damping force for the functional element 30 which needs to damp vibration. Under the condition that the load of the functional element 30 of the vehicle is greater than or equal to the first preset threshold, the second end 22 of the first elastic element 10 and the fourth end 22 of the second elastic element 20 are both pressed, at this time, the functional element 30 abuts against the fourth end 22 of the second elastic element 20, and the first elastic element 10 and the second elastic element 20 together provide a damping force for the functional element 30 needing vibration damping.
In this way, the suspension device can be adapted to different road conditions, both flat and off-road. For example, under the flat road condition of an urban scene, the load applied by the functional element 30 to the suspension device is small, and under the condition that the load is smaller than the first preset threshold, the functional element 30 can be provided with a good vibration and noise reduction effect only through the first elastic element 10, so that the functional element 30 is prevented from being damaged or even failing, and the driving safety of the vehicle is improved.
For another example, under the off-road conditions of the scenes such as desert, jungle, mountain road, etc., the load applied by the functional element 30 on the suspension device is large, and under the condition that the load is greater than or equal to the first preset threshold, the functional element 30 abuts against the fourth end 22 of the second elastic element 20, the gap between the functional element 30 and the fourth end 22 is eliminated, the first elastic element 10 and the second elastic element 20 jointly provide sufficient vibration reduction and noise reduction effects for the functional element 30, so that the functional element 30 is prevented from being easily damaged or even losing efficacy under the off-road conditions, the driving safety of the vehicle is further improved, and the use scenes of the vehicle are enriched.

Because the vibration and noise of a larger amplitude can be generated along with the movement of the vehicle, the vibration and noise of the vehicle are reduced, so that the comfort of people riding the vehicle is improved.
In the embodiment of the present application, specifically, the first preset threshold may be set to 100N, 130N, 150N, and the like, and may be set according to a model of a vehicle, a model weight of the functional component 30, and the like, and a specific numerical value of the first preset threshold may not be limited in the embodiment of the present application.
Specifically, in the embodiment of the present application, the second elastic element 20 and the first elastic element 10 may be coaxially disposed, the first end 11 of the first elastic element 10 and the third end 21 of the second elastic element 20 are both disposed near one side of the vehicle body, and the second end 12 of the first elastic element 10 and the fourth end 22 of the second elastic element 20 are both disposed near one side of the functional element 30.

The driving mechanism 40 drives the third end 21 of the second elastic member 20 to move toward the fourth end 22, so as to enhance the damping force of the second elastic member 20.
For example, in the case that the load of the functional element 30 is greater than or equal to the second preset threshold, the actuating driving mechanism 40 drives the third end 21 of the second elastic element 20 to move towards the fourth end 22, so that the rigidity of the second elastic element 20 is enhanced, and the vibration and noise reduction effects on the functional element 30 are enhanced, so that the suspension device can adapt to more rugged and complicated off-road conditions.
In this embodiment of the application, specifically, the second preset threshold is greater than the first preset threshold, the second preset threshold may be set to 150N, 180N, 200N, and the like, and may be set according to a vehicle type of a vehicle, a model weight of the functional component 30, and the like, and a specific numerical value of the second preset threshold may not be limited in this embodiment of the application.

For example, under the flat road condition of an urban scene, the ECU of the whole vehicle can acquire the acceleration of the vehicle as 3m/s 2 And correspondingly, when the opening of the accelerator pedal is in the range of 0-30%, and the load of the functional element 30 is smaller than the first preset threshold, the first elastic element 10 provides a buffer force for the functional element 30 to reduce vibration and noise, and the driving mechanism 40 does not work.
For another example, under a light off-road condition in a desert scene, the ECU of the whole vehicle can acquire the acceleration of the vehicle as 5m/s 2 And corresponding to the range of 30% -80% of the accelerator pedal opening, at this time, the load of the functional element 30 is greater than or equal to the first preset threshold value and is smaller than the second preset threshold value, the first elastic element 10 and the second elastic element 20 jointly provide a buffer force for the functional element 30 to reduce vibration and noise, and the driving mechanism 40 does not work.
For another example, under deep off-road conditions in jungle or mountain road scenes, the entire ECU can acquire the acceleration of the vehicle as 8m/s 2 And corresponding to the range of 80% -100% of the accelerator pedal opening, at this time, the load of the functional element 30 is greater than or equal to the second preset threshold, the vehicle ECU may enable the driving mechanism 40 to drive the second elastic element 20 to move, so as to enhance the rigidity of the second elastic element 20, and enable the second elastic element 20 to provide a larger buffer force for the functional element 30 to reduce vibration and noise.
