The invention provides a vibration damper.
Referring to fig. 1 to 6, the vibration damping device is used for a vehicle seat, and comprises a seat support plate 100, a vehicle body connecting plate 200, an elastic bearing assembly 300 and a driving assembly 400. The elastic carrier assembly 300 has one end connected to the seat support plate 100 and the other end connected to the vehicle body attachment plate 200. A driving assembly 400 extending from a region below a vehicle body facing side of the vehicle body attachment plate to a side of the seat support plate facing the vehicle body attachment plate (i.e., from a region below a lower surface of the vehicle body attachment plate 200 to a lower surface of the seat support plate 100), the driving assembly 400 driving the seat attachment plate 100 to move in a telescoping direction of the elastic carrier assembly 300. When the vehicle runs to the condition that the pit of the road surface is uneven or needs to go up and down a slope, the vehicle can generate acceleration in the vertical direction and then generate exciting force in the vertical direction, in the prior art, the exciting force acts on the elastic bearing assembly, the elastic bearing assembly stretches or shortens and attenuates the exciting force to realize passive vibration reduction, however, the elastic bearing assembly has rigidity, the vibration reduction effect is limited, and particularly when the vehicle encounters a bumpy road surface, the damping of the elastic bearing assembly cannot be adjusted, so that the elastic bearing assembly cannot attenuate the exciting force or needs longer attenuation time, and passengers are easy to fatigue. The technical scheme provided by the invention is that the relative height of the seat support plate and the vehicle body connecting plate is changed through the driving component, so that the up-and-down shaking condition of the vehicle body caused by bumpy road conditions is changed, namely, the reverse motion of the vehicle body and the motion direction of the vehicle body is given, so that most of external excitation is counteracted, active vibration reduction is realized, the vibration reduction effect is improved, the technical problem of poor vibration reduction effect of a spring in the prior art is overcome, and the elastic bearing component plays roles of auxiliary bearing and certain guiding.
Alternatively, the two elastic bearing assemblies 300 are disposed on two sides of the driving assembly 400 with the axis of the driving assembly 400 as a symmetry axis, and in the implementation process, the axis of the driving assembly 400 may be the geometric center line of the driving assembly 400 or the axis of the telescopic component of the driving assembly 400, and the axes of the two elastic bearing assemblies 300 are consistent with the geometric center line of the driving assembly 400. In consideration of the fact that the seat has a certain weight, if the elastic bearing assemblies 300 are asymmetrically arranged or simultaneously arranged at one side of the driving assembly 400, the seat support plate has a risk of tilting and swinging during vibration reduction, in the present invention, the elastic bearing assemblies 300 are arranged at both sides of the driving assembly 400 mainly to enable the variation amounts of the two elastic bearing assemblies 300 during auxiliary vibration reduction to be uniform as much as possible, and the elastic deformation of the elastic bearing assemblies 300 is prevented from being unsynchronized during external excitation attenuation to cause the seat support plate 100 to swing.
Optionally, each elastic bearing assembly 300 includes a spring 300a and two spring limiting tubes 300b, wherein the two spring limiting tubes 300b are fixedly connected with the seat support plate 100 and the vehicle body connecting plate 200 respectively, two ends of the spring 300a extend into the two spring limiting tubes 300b and are fixedly connected with the seat support plate 100 and the vehicle body connecting plate 200 respectively, and the extending and retracting direction of the spring 300a is the extending and retracting direction of the elastic bearing assembly 300, in the specific implementation process, the two spring limiting tubes 300b are coaxially arranged to limit the extending and retracting direction of the spring 300a, namely the extending and retracting direction of the elastic bearing assembly 300, and by adopting the spring limiting tubes 300b, the non-axial force of the spring 300a can be reduced, so that the seat cannot swing when the external exciting force is attenuated.
Alternatively, the drive assembly 400 is a linear motor, which does not require a transmission structure to convert the rotational motion into a linear motion, thus making the structure of the vibration damping device simple. In a specific implementation process, the linear motor includes an electromagnetic coil assembly and a magnetic steel expansion plate 400a, and traveling wave magnetic fields generated by a mover (the magnetic steel expansion plate 400 a) and a stator (the electromagnetic coil assembly is not shown) cause the magnetic steel expansion plate 400a to move bi-directionally in an expansion direction. The majority of the external vibration amplitude is counteracted by the linear motor, namely the relative motion of the electromagnetic coil and the magnetic steel expansion plate, in the implementation process, the linear motor can adopt the existing product, and the details are not repeated, in the implementation process, the magnetic steel expansion plate 400a is provided with 4 sliding rails 400a-1, the sliding rails 400a-1 are in sliding connection with the sliding rail sliding blocks 400b, the sliding rail sliding blocks 400b are kept fixed, a moving pair between the sliding rails 400a-1 and the sliding rail sliding blocks 400b can keep the expansion direction of the magnetic steel expansion plate 400a, and in the implementation process, the magnetic steel expansion plate 400a is fixedly connected with the seat connecting plate 100. Because the linear motor is easy to support the rotor by magnetic suspension, a certain air gap is always kept between the rotor and the stator without contact, the contact friction resistance between the stator and the rotor is eliminated, the sensitivity, the rapidity and the follow-up performance of the system are greatly improved, and the driving assembly can rapidly respond to the randomness of the road surface condition.
Optionally, the vibration damping device further comprises a guide assembly 500, wherein the guide assembly 500 comprises a guide pillar 500a and a mounting seat 500b, one end of the guide pillar 500a is movably connected with the mounting seat 500b and moves bi-directionally in the telescopic direction of the elastic bearing assembly 300, the other end of the guide pillar 500a is fixedly connected with the seat support plate 100, the bottom end of the mounting seat 500b is fixedly connected with the car body connecting plate 200, in the specific implementation process, the mounting seat 500b can be welded to the car body connecting plate 200 or fixedly connected through threads, the guide pillar 500a can be welded to the seat support plate 100 or fixedly connected through threads, the mounting seat 500b is a part with a hollow structure such as a graphite copper pillar (self-lubricating bearing) or a guide seat hole, the hollow structure of the guide pillar 500a and the mounting seat 500b is movably connected, such as clearance fit or transition fit, the axial direction of the guide pillar 500a is the telescopic direction of the elastic bearing assembly 300, the guide pillar 500a slides in the hollow structure when the driving assembly 400 is executed, and the guide pillar can be moved by a rigid component (understood to be a rigid component which can be understood as a rigid component) which can be effectively prevented from damping the vibration of the seat support plate 300 when the bearing assembly is elastically and is elastically loaded. Alternatively, two other elastic bearing assemblies are disposed on both sides of the guide assembly 500 with the axis thereof as a symmetry axis.
Optionally, the vibration damping device further comprises a support assembly 600; the first end surface 600a of the support member 600 is fixed to the side of the vehicle body connection plate 200 where the elastic bearing member 300 is provided, and the support member 600 extends in the telescopic direction without contacting the seat support plate 100, and in a specific implementation, the first end surface 600a of the support member 600 is screwed to the side of the vehicle body connection plate 200 where the elastic bearing member 300 is provided; the support assembly 600 extends in the telescoping direction of the elastic bearing assembly 300 but the second end surface 600b thereof is not in contact with the seat support plate 100, the opposite first side surfaces 600c of the support assembly 600 are respectively in contact with the rail sliders 400b at both sides of the drive assembly 400, specifically, the first side surfaces 600c are in surface contact with the rail sliders 400b and are fixed by threads, while the rail sliders 400b remain stationary, the second side surfaces 600d of the support assembly 600 are in contact with the outer walls 400d of the drive assembly 400, specifically, the second side surfaces 600d are perpendicular to each other, the magnetic steel telescoping plates 400a are in sliding contact with the second side surfaces and the second side surfaces 600d are in fixed contact with the outer walls of the electromagnetic coils, and the support assembly 600 can prevent the drive assembly from losing stability due to being excessively compressed when the drive assembly 400 is subjected to axial magnetic steel tensile force due to the vertical installation of the drive assembly 400, and maintain the drive assembly 400 from being deflected when the drive assembly is not subjected to compressive force.
Alternatively, the distance between the seat support plate 100 and the second end surface 600b of the support assembly 600 is greater than the maximum compression of the resilient load bearing assembly 300. In this way, even if the driving assembly 400 pulls the seat support plate 100 toward the vehicle body connection plate 200 (the elastic bearing assembly 300 is compressed), the seat support plate 100 does not rigidly contact the support assembly 600, preventing the seat support plate 100 from rigidly striking, and thus effectively preventing the occupant from being subjected to a rigid impact load.
