The invention provides a vibration damping device.
Referring to fig. 1 to 6, the vibration damping device for a vehicle seat includes a seat support plate 100, a vehicle body connection plate 200, an elastic carrier 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 connection plate 200. A driving assembly 400 extending from a region below a side of the vehicle body connecting plate facing the vehicle body to a side of the seat support plate facing the vehicle body connecting plate (i.e., from a region below a lower surface of the vehicle body connecting plate 200 to a lower surface of the seat support plate 100), the driving assembly 400 moving the seat connecting plate 100 in a telescopic direction of the elastic carrier assembly 300. When a vehicle runs to a concave pit on a road surface or needs to go up and down a slope, the vehicle can generate acceleration in the vertical direction and further generate exciting force in the vertical direction, in the prior art, the exciting force acts on the elastic bearing component, the elastic bearing component extends or shortens to attenuate the exciting force to realize passive vibration attenuation, however, the elastic bearing component has rigidity and limited vibration attenuation effect, and particularly, when the vehicle runs on a bumpy road surface, the damping of the elastic bearing component cannot be adjusted, so that the elastic bearing component cannot attenuate the exciting force or needs longer attenuation time, and the vehicle and passengers are easy to fatigue. The technical scheme provided by the invention is as follows: the relative height of the seat supporting plate and the vehicle body connecting plate is changed through the driving assembly, so that the condition of vertical shaking of the vehicle body caused by bumpy road conditions is changed, namely, the vehicle body moves in the direction opposite to the moving direction of the vehicle body, most external excitation is offset, active vibration reduction is realized, the vibration reduction effect is improved, and the technical problem that the spring vibration reduction effect is poor in the prior art is solved; and the elastic bearing component plays a role of auxiliary bearing and certain guiding.
Optionally, two elastic bearing assemblies 300 are arranged on two sides of the driving assembly 400 with the axis of the driving assembly 400 as a symmetry axis; in a specific implementation, the axis of the driving assembly 400 may be a geometric centerline of the driving assembly 400, or may be an axis of a telescopic member of the driving assembly 400; the axes of the two elastomeric bearing assemblies 300 are coincident with the geometric centerline of the drive assembly 400. Considering that the seat has a certain weight, if the elastic carrier assembly 300 is disposed asymmetrically or at the same time on one side of the driving assembly 400, the seat support plate has a risk of swinging askew when absorbing vibration; in the present invention, the elastic bearing assemblies 300 are disposed on both sides of the driving assembly 400, so that the variation of the two elastic bearing assemblies 300 during auxiliary damping can be as consistent as possible, and the seat support plate 100 is prevented from swinging due to asynchronous elastic deformation of the elastic bearing assemblies 300 during damping of external excitation.
Optionally, each elastic bearing assembly 300 comprises a spring 300a and two spring limiting pipes 300b, wherein the two spring limiting pipes 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 pipes 300b respectively and are fixedly connected with the seat support plate 100 and the vehicle body connecting plate 200, and the expansion direction of the spring 300a is the expansion direction of the elastic bearing assembly 300; in the specific implementation process, the two spring limiting pipes 300b are coaxially arranged to define the stretching direction of the spring 300a, that is, the stretching direction of the elastic bearing assembly 300, the non-axial force of the spring 300a can be reduced by adopting the spring limiting pipes 300b, and the seat cannot swing when the external excitation force is attenuated.
Optionally, the drive assembly 400 is a linear motor; the linear motor does not need to convert the rotary motion into linear motion, and does not need a transmission structure, so that the vibration damping device has a simple structure. In the specific implementation process, the linear motor includes an electromagnetic coil assembly and a magnetic steel expansion plate 400a, and the magnetic steel expansion plate 400a moves in two directions in the expansion direction due to a traveling wave magnetic field generated by a mover (the magnetic steel expansion plate 400a) and a stator (the electromagnetic coil assembly, not shown). Most of the external vibration amplitude is offset by the linear motor, i.e. the relative motion of the electromagnetic coil and the magnetic steel expansion plate, in the specific implementation process, the linear motor can adopt the existing product, and the details are not repeated; in the specific implementation process, the magnetic steel expansion plate 400a is provided with 4 sliding rails 400 a-1; the slide rail 400a-1 is connected with the guide rail slide block 400b in a sliding manner; the guide rail sliding block 400b is kept fixed, and a sliding pair between the sliding rail 400a-1 and the guide rail sliding block 400b can keep the telescopic direction of the magnetic steel telescopic plate 400 a; in a specific implementation process, the magnetic steel expansion plate 400a is fixedly connected to the seat connecting plate 100. Because the linear motor is easy to realize that the rotor of the linear motor is supported by magnetic suspension, a certain air gap is always kept between the rotor and the stator without contact, so that the contact friction resistance between the stator and the rotor is eliminated, the sensitivity, the rapidity and the follow-up property of a system are greatly improved, and the driving assembly can quickly respond to the randomness of road conditions.
Optionally, the vibration damping device further comprises a guide assembly 500, the guide assembly 500 comprises a guide pillar 500a and a mounting seat 500b, wherein one end of the guide pillar 500a is movably connected with the mounting seat 500b and moves in both directions 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, and the bottom end of the mounting seat 500b is fixedly connected with the vehicle body connection plate 200; in a specific implementation process, the mounting seat 500b may be welded to the vehicle body connecting plate 200, or may be fixedly connected through threads; the guide post 500a may be welded to the seat support plate 100, or may be fixedly connected by a screw; the mount 500b is a part having a hollow structure, such as a graphite copper cylinder (self-lubricating bearing) or a guide hole; the hollow structures of the guide post 500a and the mounting seat 500b are movably connected, such as a clearance fit or a transition fit; the axial direction of the guide post 500a is the telescopic direction of the elastic carrier assembly 300, and the guide post 500a slides in the hollow structure when the driving assembly 400 is actuated; in the present invention, since the guide post is a movable rigid member (it can be understood that rigidity is compared to a spring), it can effectively ensure the directionality of the elastic carrier assembly 300 when it attenuates, preventing the seat support plate 100 from swinging. Optionally, two more elastic load bearing assemblies are disposed on two 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 connecting plate 200 where the elastic support member 300 is disposed, and the support member 600 extends in the telescopic direction without contacting the seat support plate 100, and in the specific implementation process, the first end surface 600a of the support member 600 is connected to the side of the vehicle body connecting plate 200 where the elastic support member 300 is disposed through a screw thread; the support member 600 extends in the telescopic direction of the elastic carrier member 300 but the second end surface 600b thereof is not in contact with the seat support plate 100; two opposite first side surfaces 600c of the supporting assembly 600 are respectively contacted with the rail sliders 400b at two sides of the driving assembly 400, specifically, the first side surfaces 600c are in surface contact with the rail sliders 400b and are fixed by threads, and the rail sliders 400b are kept stationary at the time; the second side 600d of the supporting component 600 contacts with the outer wall 400d of the driving component 400, specifically, the second side 600d is perpendicular to the first side 600c, the magnetic steel expansion plate 400a is in sliding contact with the second side, and the second side 600d is in fixed contact with the outer wall where the electromagnetic coil is located; without being limited thereto, the magnetic steel expansion plate 400a and the second side surface 600d may also be not in contact; since the driving assembly 400 is vertically installed, it is under axial tension and pressure, and when it is under pressure, the support assembly 600 can prevent the driving assembly from losing stability due to over-pressure; also, the support assembly 600 can maintain the driving assembly 400 without deflection when it is extended or retracted.
Optionally, the distance between the seat support plate 100 and the second end face 600b of the support assembly 600 is greater than the maximum compression of the resilient load bearing assembly 300. As a result, even if the driving unit 400 pulls the seat support plate 100 toward the vehicle body connecting plate 200 (the elastic carrier assembly 300 is compressed), the seat support plate 100 does not rigidly contact the support member 600, and the seat support plate 100 is prevented from being rigidly impacted, thereby effectively preventing the occupant from being subjected to a rigid impact load.
Optionally, the invention also discloses a vibration damping system.
