Example Embodiment
[0015] Example 1
[0016] Such as figure 1 As shown, the multi-degree-of-freedom parallel mechanism damping platform for motor vehicle seats includes a fixed platform 4 and a bearing platform 3 above the fixed platform 4. The bearing platform 3 is connected to the motor vehicle seat, and the bearing platform 3 and the fixed platform 4 The three branches are connected by three branches with the same structure. The three branches are uniformly distributed around the vertical center line of the fixed platform 4 at 120°. The three branches all include a spring 7, a damper 8, a moving pair, a cylindrical pair and a rotating pair;
[0017] The fixed platform 4 is provided with a bracket 5, and the bracket 5 is equipped with a moving pair. The moving pair includes a sliding shaft 10 and a sliding block 6. The sliding shaft 10 is fixed on the supporting frame 5, and the sliding block 6 slides axially on the sliding shaft 10. A spring 7 and a damper 8 are installed between 6 and the bottom...
Example Embodiment
[0021] Example 2
[0022] On the basis of Embodiment 1, the damper 8 is a controllable passive electromagnetic damper, which is connected to the current regulating unit and the force sensor, and the current regulating unit and the force sensor are connected to the controller.
[0023] The control system can be turned on or off selectively. When the control system is closed, the electromagnetic damper itself has certain damping characteristics and works in a passive damping state; when the control system is turned on, the electromagnetic damper detected by the force sensor The data is transmitted to the controller, and the controller determines the current input to the electromagnetic damper according to the data simulation calculation, thereby changing the damping value, and optimizing the vibration reduction effect while avoiding the resonance frequency of the human body.
