Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
As shown in Figure 1 to Figure 3, vibration absorber 10 of the invention, including air spring 11, cross brace 12, have bullet
Spring 13, upper backup pad 14, pedestal 15, damping system 20, detection part 30, controller 40.Seat 60
The cross brace 12 is arranged between the upper backup pad 14 and pedestal 15, and cross brace 12 includes left support frame
121 and right support frame 122, upper end, the lower end of left support frame 121 and right support frame 122 can be respectively along upper backup pads 14, pedestal 15
On slideway movement, be rotatably coupled by crossbeam 123, can be rotated around crossbeam 123 between the two, passed through and adjust crossbeam
123 upper and lower position can realize that the cross angle of left support frame 121 and right support frame 122 reduces or increases.Pass through left support frame
121 and right support frame 122 to guarantee that upper backup pad 14 is in a horizontal position, and by left support frame 121 and right support frame 122 around
Crossbeam 123 is close to each other or far from movement, realizes and moves to the up and down adjustment of upper backup pad 14.
Described 11 one end of air spring is connected on pedestal 15, and the other end is connected on crossbeam 123.Pass through air spring 11
Upward thrust can be applied to crossbeam 123, reduce the cross angle of left support frame 121 and right support frame 122, support upper backup pad
14 move upwards or are maintained at the state moved upwards, to fight the trend that upper backup pad 14 moves downward, reduce upper backup pad
14 amplitude.
Detection part 30 is connected with cross brace 12, for detecting the displacement and/or angle of cross brace 12.
Damping system 20, including damping vibration attenuation part 21 and damping vibration attenuation part 22, damping vibration attenuation 22 are only detecting impact work
Start to act under condition.
21 one end of damping vibration attenuation part is connected on pedestal 15, and the other end is connected on crossbeam 123；22 one end of damping vibration attenuation part
It is connected on crossbeam 123, the other end is connected on upper backup pad 14.
Damping vibration attenuation part 21 is the common damping structure of vibration absorber 10, in general job operating condition, plays vibration damping
Effect.
Damping vibration attenuation part 22 has two grades of designs, is the 1st grade in general job operating condition, does not provide damping force at this time.
Only when detection part 30 detects impact operating condition, enter the 2nd grade, intervenes work and damping force is provided.
In the case where detecting impact operating condition, 11 automatic adjustment spring inflation rate of air spring stretches to maximal work location boundary
14 direction of upper backup pad is stretched to, to reduce the amplitude of vibration absorber 10.
On the upper beam 1211,1221 for having 13 one end of spring connection left support frame 121 or right support frame 122, the other end

When air spring 11 reaches shock resistance location boundary, has spring 13 and be in starting operating position, and intervene work, locate
In tensional state, increase vibration absorber rigidity.
Shock resistance location boundary in air spring maximum inflation rate 85% or more.
Controller 40 receives the signal that detection part 30 detects, the displacement that controller 40 detect according to detection part 30 with/
Or angle changing, and with displacement preset value and/or angle preset value compared with, displacement and/or angle be greater than displacement preset value and/or
When angle preset value, judge that vibration absorber is to be in impact operating condition in general job operating condition, to control damping system
20, the movement of air spring 11.
When controller judges that vibration absorber is general job operating condition, at this point, only damping vibration attenuation part 21 and air spring 11
It plays a role, air spring 11 reduces spring inflation rate, so that its rigidity is become smaller, to improve vibration isolation rate, promote vibration comfort；
Damping vibration attenuation part 21 only provides the single damping force of needs.
When controller judges that vibration absorber is impact operating condition, controller 40 controls air spring 11 and improves spring inflation
Rate, stretches to shock resistance location boundary, and the control intervention of damping vibration attenuation part 22 is made with providing the damping force opposite with air spring 11
It has spring 13 and intervenes work.
As shown in Figure 4 and Figure 5, a kind of engineering machinery 50 uses above-mentioned vibration absorber 10 in the lower part of seat 60, in order to
Vibration absorber 10 is protected, protective case is set outside it.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
