Description
Technical field
The utility model belongs to safeguard for driver, three grades of shock absorbing seat systems of especially a kind of chaufeur.
Background technology
Along with the progress of science and technology, people's living standard is improving gradually, and the use of automobile is also more and more.It is particularly important that the driving safety of automobile also becomes.
People require also more and more higher to the traveling comfort of automobile, present driver's seat only has the shock mitigation system of single-stage, can pass to chaufeur by vehicle body after relatively poor or wheel is given a shock suddenly when the road surface, after this moment, chaufeur was subject to impact endurance test shock, vibration has appearred in the chaufeur health, causes thus the variation of driver's seat, and this can have a strong impact on the chaufeur operating and controlling vehicle, owing to the traffic accident that vehicle appearance vibrations cause is quite a few, and make the driver comfort variation.Serious vibrations can occur when particularly the incoming frequency on road surface is consistent with the natural frequency of driver's seat, seriously hinder the chaufeur operating and controlling vehicle.
Summary of the invention
The purpose of this utility model is to provide a kind of chaufeur three grades of shock absorbing seat systems, spring, spring housing and the damper that utilizes rigidity to vary in size forms the system of three grades of dampings, three grades of vibration dampings have been realized, can pass to according to the differential declines vehicle body of vibrations degree the vibrations of seat, the situation that can occur resonating hardly, can not affect the chaufeur operating and controlling vehicle, keep driver comfort, in addition native system also have advantages of simple in structure, be easy to realize and with low cost.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
Three grades of shock absorbing seat systems of a kind of chaufeur, comprise lower retainer, it is characterized in that, also comprise three grades of damping springs, the lower end of three grades of damping springs connects firmly together with damper by lower retainer, the upper end of three grades of damping springs connects firmly together with damper by holder, and the lower end of damper directly is fixed on the base of corresponding driver's seat, and the upper end of damper connects firmly with corresponding driver's seat.
Described three grades of damping springs comprise inner spring cover and the outer spring cover that from-inner-to-outer distributes, and the inner spring cover is nested with the outer spring cover, and wherein outer spring puts with outer spring, and the inner spring cover is with inner spring, and the rigidity of the ratio of rigidity inner spring of outer spring is large in addition.
The beneficial effects of the utility model are: the power that three grades of shock absorbing seat systems of this chaufeur pass to seat base vibrations according to vehicle body is carried out the vibration damping of different stage.When vehicle is subject to severe jolt or engine idle, the natural frequency of vehicle suspension part natural frequency and driving engine is more or less the same, it is severe especially that vehicle can vibrate, this moment, the system size spring was in parallel, the rigidity of vibration insulating system is maximum, systematic comparison " firmly ", the vibration that vehicle body is passed to seat base significantly decays; When vehicle was subject to than smaller tremors, the rigidity of vibration insulating system was little, systematic comparison " soft ", thus guarantee that amplitude variations is little.Three grades of shock absorbing seat systems of this chaufeur also have simple in structure, realize easily, the most important thing is that it can pass to according to the differential declines vehicle body of vibrations degree the vibrations of seat, the situation that can occur resonating hardly, this can improve driving safety and driver comfort.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Wherein, 1, lower retainer; 2, damper; 3, holder; 4, inner spring cover; 5, outer spring cover; 6, outer spring; 7, inner spring.
The specific embodiment
As shown in Figure 1, three grades of shock absorbing seat systems of chaufeur, comprise lower retainer 1, also comprise in addition three grades of damping springs, the lower end of three grades of damping springs connects firmly together with damper 2 by lower retainer 1, the upper end of three grades of damping springs connects firmly together with damper 2 by holder 3, and the lower end of damper 2 directly is fixed on the base of corresponding driver's seat, and the upper end of damper 2 connects firmly with corresponding driver's seat.Damper 2 is the cartridge type damper, and three grades of damping springs comprise inner spring cover 4 and the outer spring cover 5 that from-inner-to-outer distributes, inner spring cover 4 and outer spring cover 5 are embedded in the transmission that can move together with power, thereby can make outer spring 6 and inner spring 7 series, parallel or mutual not acting on and cause its global stiffness to change along with the variation of external environment condition, and realized the space overlap of two spring fittings, improved the compactedness of structure.Wherein on the outer spring cover 5 with outer spring 6, inner spring cover 4 is with inner spring 7, in addition, the rigidity of the ratio of rigidity inner spring of outer spring 6 is large, the rigidity of its outer spring 6 is K
1, the rigidity of inner spring 7 is K
2, also have s
1Distance during for the spring free state between the bottom surface of outer spring cover bottom surface and inner spring; S
2Distance during for the spring free state between the end face of inner spring cover end face and outer spring.
The principle of work of three grades of shock absorbing seat systems of chaufeur of the present utility model is:
1) and operation less when the suffered load of automotive wheel steadily and s
1＞0, s
2＞0 o'clock, the series connection of two springs, its global stiffness:
At this moment, the global stiffness of system is little, and is good to the attenuating of small size vibrations.
2) medium when the suffered load of automotive wheel or medium impact and s arranged
1=0; s
2＞0 o'clock, the inner spring compression was limited, its global stiffness: C
j=k
1
3) large when the suffered load of automotive wheel or greater impact and s arranged
1=0, s
2=0 o'clock, two springs were in parallel, its global stiffness: C
j=k
1+ k
2At this moment, system stiffness is maximum, and severe jolt is significantly decayed.
